  [HP INVENT LOGO]
                                                                   [COMPAQ LOGO]


Dear HP and Compaq shareowners:



   On behalf of the boards of directors and management teams of both
Hewlett-Packard Company and Compaq Computer Corporation, we are pleased to
deliver our joint proxy statement/prospectus for the merger involving HP and
Compaq. Upon completion of the merger, holders of Compaq common stock will be
entitled to receive 0.6325 of a share of HP common stock for each share of
Compaq common stock they hold at that time. HP common stock is listed on the
New York Stock Exchange and the Pacific Exchange under the trading symbol "HWP."


   The boards of directors of HP and Compaq strongly recommend the
merger--recommendations based upon months of analysis, investigation and
deliberation designed to reach a result to enhance shareowner value.

   The technology industry is characterized by rapid change, ever-evolving
customer demands and intense competition. Our ability to continue building
successful and sustainable enterprises requires thoughtful and strategic
responses to such challenging industry dynamics. The closer you look, the more
you will see that the merger is the very best way to:

  .   secure our market leadership in the fastest growing segments of our
      industry;

  .   strengthen and improve the profitability of our businesses;

  .   ensure continued investment in technology, research & development and
      innovation; and

  .   improve our financial strength and increase our earnings power.

   It is rare that a technology company has the opportunity to both
substantially advance its market position and substantially reduce its cost
structure through a merger. In this case, it is possible because HP and Compaq
are pursuing the same strategies and have complementary capabilities--the
hallmarks of successful mergers. We believe that the result will be enhanced
value for shareowners, a portfolio of market-leading products and services
offering compelling solutions for customers and partners, and expanded
opportunities for our employees.


   We encourage you to read this joint proxy statement/prospectus, which
includes important information about the merger. In addition, the section
entitled "Risk Factors" beginning on page 23 of this joint proxy
statement/prospectus contains a description of risks that you should consider
in evaluating the merger.





   Completion of the merger requires HP shareowners to approve the issuance of
shares of HP stock in connection with the merger and requires Compaq
shareowners to approve and adopt the merger agreement and approve the merger.
HP and Compaq have scheduled special meetings of their shareowners to obtain
these approvals on March 19, 2002 and March 20, 2002, respectively. Information
regarding these special meetings is included in this joint proxy
statement/prospectus. The HP board of directors recommends that HP shareowners
vote "FOR" the proposal to approve the issuance of shares of HP common stock in
connection with the merger. The Compaq board of directors recommends that
Compaq shareowners vote "FOR" the proposal to approve and adopt the merger
agreement and approve the merger.



   Please vote "FOR" your company's proposal by signing and dating the enclosed
WHITE proxy card or voting instruction card today and returning it in the
pre-addressed envelope provided.


   Thank you for your support.

   Sincerely,


/s/ Carleton S. Fiorina     /s/ Michael D. Capellas

    Carleton S. Fiorina         Michael D. Capellas


   Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of the shares of HP common stock to be
issued in connection with the merger or determined whether this joint proxy
statement/prospectus is truthful or complete. Any representation to the
contrary is a criminal offense.


   This joint proxy statement/prospectus is dated February 4, 2002 and is first
being mailed to shareowners of each of HP and Compaq on or about February 6,
2002.

Meeting Admission You are entitled to attend the special meeting only if you
                  were an HP shareowner or joint holder as of the close of
                  business on January 28, 2002 or hold a valid proxy for the
                  special meeting. You should be prepared to present photo
                  identification for admittance. In addition, if you are a
                  record holder or hold your shares through HP's TAXCAP or
                  Stock Ownership Plan, your name will be verified against the
                  list of record holders or plan participants on the record
                  date prior to being admitted to the meeting. If you are not a
                  record holder but hold shares through a broker or nominee
                  (i.e., in street name), you should provide proof of
                  beneficial ownership on the record date, such as your most
                  recent account statement prior to January 28, 2002, or other
                  similar evidence of ownership. If you do not provide photo

                  above upon request, you will not be admitted to the special
                  meeting.



                  The special meeting will begin promptly at 8:00 a.m., local
                  time. Check-in will begin at 6:30 a.m., local time, and you
                  should allow ample time for the check-in procedures.



Voting            Your vote is very important. Whether or not you plan to
                  attend the special meeting, we encourage you to read this
                  joint proxy statement/prospectus and submit your WHITE proxy
                  or voting instructions for the special meeting as soon as
                  possible. You may submit your proxy or voting instructions
                  for the special meeting by completing, signing, dating and
                  returning the WHITE proxy card or voting instruction card in
                  the pre-addressed envelope provided. For specific

                  The HP board of directors urges you to discard any green
                  proxy or voting instruction cards sent to you by a dissident
                  group which is soliciting proxies against the proposal to
                  approve the issuance of shares of HP common stock in
                  connection with the merger. If you have previously signed a
                  green proxy or voting instruction card sent by the dissident
                  group, the HP board of directors urges you to sign, date and
                  return the enclosed WHITE proxy card or voting instruction
                  card for the HP special meeting, which will revoke any
                  earlier dated proxy or voting instruction cards sent by the
                  dissident group which you may have signed.

                    QUESTIONS AND ANSWERS ABOUT THE MERGER

General Questions and Answers

Q: Why am I receiving this joint proxy statement/prospectus?

A: HP and Compaq have agreed to combine their businesses under the terms of a
   merger agreement that is described in this joint proxy statement/prospectus.
   A copy of the merger agreement is attached to this joint proxy
   statement/prospectus as Annex A.


   In order to complete the merger, HP shareowners must approve the issuance of
   shares of HP common stock in connection with the merger and Compaq
   shareowners must approve and adopt the merger agreement and approve the
   merger. Each of HP and Compaq will hold a special meeting of its respective
   shareowners to obtain these approvals. This joint proxy statement/prospectus
   contains important information about the merger and the special meeting of
   each of HP and Compaq, and you should read it carefully. For HP shareowners,
   the enclosed WHITE voting materials for the HP special meeting allow you to
   vote your shares of HP common stock without attending the HP special
   meeting. For Compaq shareowners, the enclosed WHITE voting materials for the
   Compaq special meeting allow you to vote your shares of Compaq common stock
   without attending the Compaq special meeting.


   Your vote is important. We encourage you to vote as soon as possible. For
   more specific information on how to vote, please see the questions and
   answers for each of HP and Compaq shareowners below.


Q: Why are HP and Compaq proposing the merger? (see page 56)


A: HP and Compaq share a conviction that advances in technology, increased
   competition and changing customer requirements are rapidly transforming the
   structure and economics of the information technology industry in ways that
   demand quick and decisive action to remain competitive. HP and Compaq also
   share a belief that failure to take quick and decisive action to
   comprehensively address these market trends will weaken our respective
   competitive positions and result in the deterioration of our respective
   businesses. After rigorously reviewing numerous strategic alternatives to
   address the opportunities and challenges facing our companies, the boards of
   directors of both HP and Compaq reached the same conclusion--this merger
   represents the single best strategic alternative for our respective
   companies and is the strategy most likely to deliver increased value to our
   respective shareowners. Specifically, we believe the merger will:

   .   enhance our competitive position in a number of important businesses;

   .   strengthen our sales force;

   .   improve our relationships with customers, partners and employees;


   .   generate annual cost savings of at least $2.5 billion--which we believe
       creates a present value to shareowners of $5-$9 per share of the
       combined company (based on the assumptions described in the section
       entitled "Reasons for the Merger--Financial Benefits of the Merger"
       beginning on page 59 of this joint proxy statement/prospectus); and


   .   improve the operating margins of our businesses.

Q: When do HP and Compaq expect to complete the merger?


A: HP and Compaq currently plan to complete the merger in the first half of
   calendar year 2002. However, we cannot predict the exact timing of the
   completion of the merger because the merger is subject to governmental and
   regulatory review processes and other conditions.


                                      1




Q: How do the boards of directors of HP and Compaq recommend that I vote? (see
   pages 36 and 41)


A: The HP board of directors recommends that HP shareowners vote "FOR" the
   proposal to approve the issuance of shares of HP common stock in connection
   with the merger.

   The Compaq board of directors recommends that Compaq shareowners vote "FOR"
   the proposal to approve and adopt the merger agreement and approve the
   merger.

Q: What should I do now?

A: Please review this joint proxy statement/prospectus carefully and sign, date
   and return each WHITE proxy card and voting instruction card you receive as
   soon as possible.


Q: What should I do if I receive more than one set of voting materials? (see
   pages 36 and 41)



A: Please complete, sign, date and return each WHITE proxy card and voting
   instruction card that you receive. You may receive more than one set of
   voting materials, including multiple copies of this joint proxy
   statement/prospectus and multiple WHITE proxy cards or voting instruction
   cards. For example, if you hold your shares in more than one brokerage
   account, you will receive a separate voting instruction card for each
   brokerage account in which you hold shares. If your shares are held in more
   than one name, or if you hold shares through HP's TAXCAP or Stock Ownership
   Plan in addition to other holdings, you will receive more than one proxy or
   voting instruction card. In addition, if you are a shareowner of both HP and
   Compaq, you may receive one or more WHITE proxy cards or voting instruction
   cards for HP and one or more WHITE proxy cards or voting instruction cards
   for Compaq. If you are a shareowner of both HP and Compaq, please note that
   a vote for the issuance of shares in connection with the merger for the HP
   special meeting will not constitute a vote for the proposal to approve and
   adopt the merger agreement and approve the merger for the Compaq special
   meeting, and vice versa. Therefore, please sign, date and return each WHITE
   proxy and voting instruction card you receive, whether from HP or Compaq.


Questions and Answers for HP Shareowners


Q: When and where is the HP special meeting? (see page 36)



A: The special meeting of HP shareowners will be held at 8:00 a.m., local time,
   on March 19, 2002, at The Flint Center, 21250 Stevens Creek Boulevard,
   Cupertino, California. Check-in will begin at 6:30 a.m. Please allow ample
   time for the check-in procedures.



Q: Does the color of the proxy card matter? (see page 36)


A: WHITE proxy cards and voting instruction cards are being solicited on behalf
   of the HP board of directors from HP shareowners in favor of the proposal to
   approve the issuance of shares of HP common stock in connection with the
   merger. The HP board of directors urges shareowners to sign, date and return
   each WHITE proxy or voting instruction card promptly.

   The green proxy cards are being sent to HP shareowners by a dissident group
   soliciting proxies against the proposal. The HP board of directors urges HP
   shareowners to discard any green proxy or voting instruction card sent by
   the dissident group.

                                      2




Q: How can I attend the HP special meeting? (see page 36)



A: You are entitled to attend the special meeting only if you were an HP
   shareowner or joint holder as of the close of business on January 28, 2002,
   or you hold a valid proxy for the special meeting. You should be prepared to
   present photo identification for admittance. In addition, if you are a
   record holder or hold your shares through HP's TAXCAP or Stock Ownership
   Plan, your name will be verified against the list of record holders or plan
   participants on the record date prior to being admitted to the meeting. If
   you are not a record holder but hold shares through a broker or nominee
   (i.e., in street name), you should provide proof of beneficial ownership on
   the record date, such as your most recent account statement prior to January
   28, 2002, or other similar evidence of ownership. If you do not provide
   photo identification or comply with the other procedures outlined above upon
   request, you will not be admitted to the special meeting.



   The special meeting will begin promptly at 8:00 a.m. Check-in will begin at
   6:30 a.m., and you should allow ample time for the check-in procedures.



Q: What is the vote of HP shareowners required to approve the issuance of
   shares of HP common stock in connection with the merger? (see page 37)


A: The issuance of shares of HP common stock in connection with the merger
   requires an affirmative vote of a majority of the votes cast at the HP
   special meeting, provided that the total vote cast on the proposal
   represents over 50% of all shares of HP common stock entitled to vote on the
   proposal.


Q: As an HP shareowner, how can I vote? (see page 36)


A: You may direct your vote without attending the HP special meeting. If you
   are a shareowner of record, you may vote by granting a proxy. If you hold
   shares in street name, you may vote by submitting voting instructions to
   your broker or nominee. Simply complete, sign and date your WHITE proxy card
   or voting instruction card, as applicable, for the HP special meeting and
   mail it in the pre-addressed envelope provided.  There will be no telephone
   or Internet voting for the HP special meeting.


   If you are a shareowner of record, you may also vote in person at the HP
   special meeting. If you hold shares in a stock brokerage account or if your
   shares are held by a bank or nominee (i.e., in street name), you may not
   vote in person at the HP special meeting unless you obtain a signed proxy
   from the record holder giving you the right to vote the shares. You will
   also need to present photo identification and comply with the other
   procedures described in "Admission to the Special Meeting" on page 36.



   For a more detailed explanation of the voting procedures, please see the
   section entitled "Voting Procedures" beginning on page 38 of this joint
   proxy statement/prospectus.



Q: As an HP shareowner, what happens if I do not vote? (see page 37)


A: Failure to vote or give voting instructions to your broker or nominee for
   the HP special meeting could make it more difficult to meet the voting
   requirement that the total vote cast on the proposal represents over 50% of
   all shares of HP common stock entitled to vote on the proposal. Therefore,
   we urge you to vote.


Q: I have received a green proxy or voting instruction card. Should I sign it
   and mail it? (see page 37)


A: No. The HP board of directors urges HP shareowners to discard any green
   proxy or voting instruction cards sent to you by the dissident group which
   is soliciting proxies against the proposal.

                                      3




Q: I have already submitted a green proxy or voting instruction card. May I
   change my vote? (see page 39)


A: Yes. You may revoke a previously granted green proxy or voting instruction
   at any time prior to the special meeting by:


   .   signing and returning a later dated WHITE proxy or voting instruction
       card for the HP special meeting; or



   .   attending the HP special meeting and voting in person, as described in
       the section entitled "The Special Meeting of HP Shareowners" beginning
       on page 36 of this joint proxy statement/prospectus.



   Only your last submitted proxy or voting instruction card will be
   considered. Please submit a WHITE proxy or voting instruction card for the
   HP special meeting as soon as possible. You do not need to contact the
   dissident group to revoke any previously granted proxy you may have given to
   the dissident group by returning a green proxy card.


Q: As an HP shareowner, who can help answer my questions?

A: If you have any questions about the merger or how to vote or revoke your
   proxy, you should contact:

Q: What is the vote of Compaq shareowners required to approve and adopt the
   merger agreement and approve the merger? (see page 42)


A: Approval and adoption of the merger agreement and approval of the merger
   requires the affirmative vote of the holders of a majority of the shares of
   Compaq common stock outstanding as of the record date for the Compaq special
   meeting.


Q: As a Compaq shareowner, what happens if I do not vote? (see page 42)


A: Failure to vote or give voting instructions to your broker or nominee for
   the Compaq special meeting will have the same effect as voting "against" the
   proposal to approve and adopt the merger agreement and approve the merger.
   Therefore, we urge you to vote.


Q: As a Compaq shareowner, what will I receive upon completion of the merger?
   (see page 90)


A: Upon completion of the merger, you will be entitled to receive 0.6325 of a
   share of HP common stock for each share of Compaq common stock you own at
   the effective time of the merger. Instead of a fractional share of HP common
   stock, you will be entitled to receive an amount of cash equal to the value
   of the fractional share remaining after aggregating all of your Compaq
   shares held in a single account, based on an average closing price of HP
   common stock as reported on the New York Stock Exchange composite
   transactions tape.


Q: As a Compaq shareowner, will I be able to trade the HP common stock that I
   receive in connection with the merger? (see page 110)


A: The shares of HP common stock issued in connection with the merger will be
   freely tradeable, unless you are an affiliate of Compaq, and will be listed
   on the New York Stock Exchange and the Pacific Exchange under the symbol
   "HWP." Generally, persons who are deemed to be affiliates of Compaq must
   comply with Rule 145 under the Securities Act of 1933 if they wish to sell
   or otherwise transfer any of the shares of HP common stock received in
   connection with the merger. You will be notified if you are an affiliate of
   Compaq.


Q: As a Compaq shareowner, how can I vote? (see page 41)


A: If you are a shareowner of record, you may submit a proxy for the Compaq
   special meeting (1) by completing, signing, dating and returning the WHITE
   proxy card in the pre-addressed envelope provided, (2) by using the
   telephone, or (3) by using the Internet. For specific instructions on how to
   use the telephone or the Internet to submit a proxy for the Compaq special
   meeting, please refer to the instructions on your proxy card.


   If you hold your shares of Compaq common stock in a stock brokerage account
   or if your shares are held by a bank or nominee (i.e., in street name), you
   must provide the record holder of your shares with instructions on how to
   vote your shares. Please check the WHITE voting instruction card used by
   your broker or nominee to see if you may vote using the telephone or the
   Internet. If you are a shareowner of record, you may also vote at the Compaq
   special meeting. If you hold shares in a stock brokerage account or if your
   shares are held by a bank or nominee (i.e., in street name), you may not
   vote in person at the Compaq special meeting unless you obtain a signed
   proxy from the record holder giving you the right to vote the shares. You
   will also need to present photo identification and comply with the other
   procedures described in "Admission to the Special Meeting" on page 41.

Q: As a Compaq shareowner, should I send in my stock certificates at this time?
   (see page 90)


A: Do not send in your stock certificates at this time. Promptly following
   completion of the merger, Computershare Trust Company of New York, the
   exchange agent for the merger, will send you written instructions for
   exchanging your Compaq stock certificates for book-entry ownership of HP
   common stock or, if you request, an HP stock certificate.


Q: What will happen to my options to acquire Compaq common stock or my Compaq
   stock appreciation rights (SARs)? (see page 98)


A: Options to purchase shares of Compaq common stock will be assumed by HP and
   become exercisable for shares of HP common stock after completion of the
   merger. The respective number of shares issuable upon the exercise of these
   options, and their respective exercise prices, will be adjusted using the
   exchange ratio for the merger of 0.6325 of a share of HP common stock for
   each share of Compaq common stock. Compaq SARs will be assumed by HP in a
   similar manner as options to purchase Compaq common stock.


Q: How will the merger affect my participation in the Compaq employee stock
   purchase plan? (see page 98)


A: Compaq will terminate the Compaq employee stock purchase plan before the
   merger is completed, and any purchase period then in effect will be
   shortened. Compaq will make adjustments under the Compaq employee stock
   purchase plan to reflect the shortened purchase period.

Q: As a Compaq shareowner, who can help answer my questions?

merger agreement between the companies that is described in this joint proxy
statement/prospectus. A copy of the merger agreement is attached to this joint
proxy statement/prospectus as Annex A. Under the terms of the merger agreement,
a wholly-owned subsidiary of HP will merge with and into Compaq and Compaq will
survive the merger as a wholly-owned subsidiary of HP. Upon completion of the
merger, holders of Compaq common stock will be entitled to receive 0.6325 of a
share of HP common stock for each share of Compaq common stock they then hold.

   Heloise Merger Corporation is a newly-formed, wholly-owned subsidiary of HP.
HP formed Heloise Merger Corporation solely to effect the merger, and Heloise
Merger Corporation has not conducted and will not conduct any business during
any period of its existence.


Recommendation of the HP Board of Directors (see page 62)



   After careful consideration, the HP board of directors unanimously
determined that the merger is advisable, and is fair to and in the best
interests of HP and its shareowners, and unanimously approved the merger
agreement. The HP board of directors recommends that the HP shareowners vote
"FOR" the proposal to approve the issuance of shares of HP common stock in
connection with the merger. Among other things considered by the HP board of
directors in making this recommendation, the HP board of directors requested
and considered the written opinion of Goldman, Sachs & Co., described below,
that, as of September 3, 2001 and subject to the assumptions, considerations
and limitations set forth in its opinion, the exchange ratio provided for in
the merger agreement is fair, from a financial point of view, to HP. The
Goldman Sachs opinion addresses the fairness of the merger to HP, and the HP
board of directors has determined that the merger is advisable, and is fair to
and in the best interests of HP and its shareowners, based upon its
consideration of the Goldman Sachs opinion and numerous other factors described
in the section entitled "Consideration of the Merger by the HP Board of
Directors" beginning on page 62 of this joint proxy statement/prospectus.


                                      9




Opinion of HP Financial Advisor Regarding the Merger (see page 65)


   On September 3, 2001, Goldman Sachs delivered its written opinion to the HP
board of directors that, as of that date and subject to the assumptions,
considerations and limitations set forth in its opinion, the exchange ratio
provided for in the merger agreement is fair, from a financial point of view,
to HP. Goldman Sachs provided its opinion for the information and assistance of
the HP board of directors in connection with the board's consideration of the
merger. The Goldman Sachs opinion is not a recommendation as to how any HP
shareowner should vote with respect to the proposal to approve the issuance of
shares of HP common stock in connection with the merger.


   The full text of the written opinion of Goldman Sachs, which sets forth
assumptions made, matters considered and limitations on the review undertaken
in connection with its opinion, is attached to this joint proxy
statement/prospectus as Annex B. Shareowners of HP are urged to read the
opinion carefully and in its entirety. HP shareowners should carefully consider
the discussion of Goldman Sachs' analysis in the section entitled "Opinion of
HP Financial Advisor" beginning on page 65 of this joint proxy
statement/prospectus.



Recommendation of the Compaq Board of Directors (see page 71)


   After careful consideration, the Compaq board of directors unanimously
determined the merger is advisable, and is fair to and in the best interests of
Compaq and its shareowners, and unanimously approved the merger agreement. The
Compaq board of directors recommends that the Compaq shareowners vote "FOR" the
proposal to approve and adopt the merger agreement and approve the merger.


Opinion of Compaq Financial Advisor Regarding the Merger (see page 74)


   On September 3, 2001, Salomon Smith Barney Inc. delivered its written
opinion to the Compaq board of directors that, as of that date and based upon
and subject to the assumptions, considerations and limitations set forth in its
opinion, the exchange ratio provided for in the merger agreement is fair, from
a financial point of view, to the holders of Compaq common stock. The opinion
of Salomon Smith Barney does not constitute a recommendation as to how any
Compaq shareowner should vote with respect to the proposal to approve and adopt
the merger agreement and approve the merger.


   The full text of the written opinion of Salomon Smith Barney, which sets
forth assumptions made, matters considered and limitations on the review
undertaken in connection with the opinion, is attached to this joint proxy
statement/prospectus as Annex C. Compaq shareowners are urged to read the
opinion carefully and in its entirety. Compaq shareowners should carefully
consider the discussion of Salomon Smith Barney's analysis in the section
entitled "Opinion of Compaq Financial Advisor" beginning on page 74 of this
joint proxy statement/prospectus.



Some HP and Compaq Directors and Executive Officers Have Interests in the
Merger (see page 83)



   Some of the directors and executive officers of HP and Compaq have personal
interests in the merger that are different from the interests of other HP and
Compaq shareowners. These interests include potential retention payments to ten
HP executive officers (excluding Ms. Fiorina) of up to $33.1 million in the
aggregate, and potential retention payments to seven Compaq officers (excluding
Mr. Capellas) of up to $22.4 million in the aggregate, with full payment of
retention bonuses for each eligible officer who remains employed by HP through
the second anniversary of the signing of the merger agreement, assuming that
the merger is completed (in the case of eight of the HP executive officers), or
through the first anniversary of the completion of the merger (in the case of
Compaq and two HP executive officers), and with severance payments being offset
by retention payments. These interests also include employment agreements to be
negotiated promptly following the


                                      10



completion of the merger with six HP officers and five Compaq officers in
connection with the merger and the acceleration in connection with the merger
of vesting of certain stock options and restricted stock held by both employees
and directors under the terms of Compaq's equity-based incentive plans. In
addition, Ms. Fiorina and Mr. Capellas both declined the right to participate
in the retention program, but would receive severance payments should their
employment be terminated for certain reasons after the merger. Ms. Fiorina's
potential severance payment equals $8.0 million, pursuant to an agreement which
existed prior to the execution of the merger agreement, and Mr. Capellas'
potential severance payment equals $14.4 million, pursuant to an agreement
which existed prior to the execution of the merger agreement. Further, upon
completion of the merger, Compaq will make charitable contributions totaling
$6.0 million in the names of its current outside directors, which would not
otherwise have been made until each individual director's death.


Share Ownership of Directors and Executive Officers of HP and Compaq (see pages
38 and 42)


   At the close of business on the record date for the HP special meeting,
directors and executive officers of HP and their affiliates beneficially owned
and were entitled to vote approximately 4.9% of the 1,941,391,000 shares of HP
common stock outstanding on that date.

   At the close of business on the record date for the Compaq special meeting,
directors and executive officers of Compaq and their affiliates beneficially
owned and were entitled to vote less than one percent of the 1,704,636,342
shares of Compaq common stock outstanding on that date.


Directors and Executive Officers of HP Following the Merger (see page 108)


   Following the merger, five directors of Compaq who are reasonably acceptable
to HP, including Michael D. Capellas, the Chairman of the Board and Chief
Executive Officer of Compaq, are expected to join the HP board of directors. In
addition, HP expects that each committee of the HP board of directors will
include at least one Compaq designee; Carleton S. Fiorina, the Chairman of the
Board and Chief Executive Officer of HP, will step down from the nominating and
governance committee to allow for an additional outside director to join that
committee; and a Compaq designee will become the chairman of at least one of
the audit, compensation, finance and investment or nominating and governance
committees of the HP board of directors. HP plans to negotiate employment
agreements promptly following the completion of the merger with certain persons
who are current senior executives of HP and Compaq and who are expected to
become, or continue to be, senior executives of HP following the merger.


What is Needed to Complete the Merger (see page 100)


   Several conditions must be satisfied or waived before we complete the
merger, including those summarized below:

    .  receipt of required approvals from HP shareowners and Compaq shareowners;

    .  absence of any law, regulation or order making the merger illegal or
       otherwise prohibiting the merger which would have a material impact on
       HP on a combined basis with Compaq;

    .  receipt of antitrust approvals from the United States, the European
       Commission and Canada, and receipt of all other material foreign
       antitrust approvals;

    .  absence of any orders or proceedings (1) prohibiting or seeking to
       prohibit the merger which would have a material impact on HP on a
       combined basis with Compaq, (2) limiting, or seeking to limit, HP's
       ownership of Compaq or (3) seeking to compel divestiture of assets or
       other remedies, that, in each case, would be reasonably likely to have a
       material adverse effect on HP or materially adversely impact the
       benefits expected to be derived by HP on a combined basis with Compaq
       following the merger;

                                      11



    .  receipt of opinions by HP and Compaq from their respective tax counsel
       that the merger will qualify as a "reorganization" under the Internal
       Revenue Code;

    .  accuracy of each party's respective representations and warranties in
       the merger agreement, except as would not have a material adverse effect;

    .  material compliance by each party with its covenants in the merger
       agreement; and

    .  absence of a material adverse effect on HP or Compaq, respectively, from
       September 4, 2001 to the completion of the merger.


HP and Compaq are Prohibited from Soliciting Other Offers (see page 95)


   The merger agreement contains detailed provisions that prohibit HP and
Compaq and the subsidiaries of each of them, and their officers and directors,
from taking any action to solicit or engage in discussions or negotiations with
any person or group with respect to an acquisition proposal as defined in the
merger agreement, including an acquisition which would result in the person or
group acquiring more than a 10% interest in the party's total outstanding
securities, a sale of more than 10% of the party's assets or a merger or other
business combination. The merger agreement does not, however, prohibit either
party or its board of directors from considering, and in the event of a tender
or exchange offer made directly to shareowners potentially recommending, an
unsolicited bona fide written acquisition proposal from a third party if
specified conditions are met.


HP and Compaq May Terminate the Merger Agreement Under Specified Circumstances
(see page 103)


   Under circumstances specified in the merger agreement, either HP or Compaq
may terminate the merger agreement. These circumstances generally include if:

    .  the merger is not completed by May 31, 2002 (which date will be extended
       to August 30, 2002 if the merger has not been completed as a result of a
       failure to obtain required antitrust approvals or the existence of a
       governmental law, regulation or order making the completion of the
       merger illegal or otherwise prohibited);

    .  a final, non-appealable order of a court or other action or inaction of
       any governmental authority has the effect of permanently prohibiting
       completion of the merger;

    .  the required approval of the shareowners of each of HP and Compaq has
       not been obtained at its duly held special meeting;

    .  the board of directors of the other party takes any of the actions in
       opposition to the merger described as a triggering event in the merger
       agreement;

    .  the other party breaches its representations, warranties or covenants in
       the merger agreement such that its conditions to completion of the
       merger regarding representations, warranties or covenants would not be
       satisfied;

    .  there is a material adverse effect on the other party since September 4,
       2001; or

    .  the other party consents to termination.


HP or Compaq May Pay a Termination Fee Under Specified Circumstances (see page
104)


   If the merger agreement is terminated, either HP or Compaq, in specified
circumstances, may be required to pay a termination fee of $675 million to the
other party.

                                      12




The Merger is Intended to Qualify as a Reorganization for United States Federal
Income Tax Purposes (see page 106)



   The merger has been structured to qualify as a reorganization for United
States federal income tax purposes under the Internal Revenue Code, and HP and
Compaq have received the opinions of their respective counsel, attached as
exhibits 8.1 and 8.2 to the registration statement on Form S-4, of which this
joint proxy statement/prospectus forms a part, regarding such qualification.
Assuming the merger so qualifies, Compaq shareowners generally will not
recognize gain or loss for United States federal income tax purposes as a
result of receiving HP common stock in exchange for their Compaq common stock
pursuant to the merger, except with respect to cash received instead of
fractional shares of HP common stock. You should carefully read the discussion
setting forth such tax opinions in the section entitled "United States Federal
Income Tax Consequences of the Merger" beginning on page 106 of this joint
proxy statement/prospectus. Further, you are encouraged to consult your tax
advisor because tax matters can be complicated, and the tax consequences of the
merger to you will depend upon your own situation.



Accounting Treatment of the Merger (see page 107)


   HP will account for the merger under the purchase method of accounting for
business combinations.


We Have Not Yet Obtained All Required Regulatory Approvals to Complete the
Merger (see page 109)



   The merger is subject to antitrust laws. HP and Compaq have made filings
under applicable antitrust laws with the United States Department of Justice
and the United States Federal Trade Commission, the European Commission and the
Canadian Competition Bureau. HP and Compaq are not permitted to complete the
merger until the applicable waiting periods associated with those filings,
including any extension of those waiting periods, have expired or been
terminated and applicable clearances have been obtained. HP and Compaq are also
required to make other applicable foreign antitrust filings and may not
complete the merger until all material foreign antitrust approvals have been
obtained. In addition, the reviewing agencies or governments, states or private
persons, may challenge the merger at any time before or after its completion.
On January 31, 2002, the European Commission issued a formal decision clearing
the merger on the basis that it does not create or strengthen a dominant
position as a result of which effective competition would be significantly
impeded in the European Economic Area (as defined by European Community
regulations) or in a substantial part of it. On December 20, 2001, the Canadian
Competition Bureau completed its review of the proposed merger and found no
issues of competitive concern. Other than the European Commission and the
Canadian Competition Bureau, HP and Compaq have not yet obtained any of the
governmental or regulatory approvals required to complete the merger.



HP Will List Shares of HP Common Stock on the New York Stock Exchange and the
Pacific Exchange (see page 110)


   HP will use all reasonable efforts to cause the shares of HP common stock to
be issued in connection with the merger to be authorized for listing on the New
York Stock Exchange and the Pacific Exchange before the completion of the
merger, subject to official notice of issuance.


No Appraisal Rights (see page 111)


   Neither HP shareowners nor Compaq shareowners are entitled to dissenters'
rights of appraisal for their shares under the General Corporation Law of the
State of Delaware in connection with the merger.

                                      13




Recent Financial Results



   Since the announcement of the merger, each of HP and Compaq has released
updated financial results. See the sections entitled "Summary Selected
Historical Consolidated Financial Data of HP" and "Summary Selected Historical
Consolidated Financial Data of Compaq" below. In addition, since the
announcement of the merger, Wall Street estimates of the future financial
performance of HP and Compaq have been available that differ from the estimates
considered by the HP board of directors at the time it approved the merger.
Specifically, First Call consensus estimates used in HP's solicitation

                    COMPARATIVE PER SHARE MARKET PRICE DATA

   HP common stock trades on the New York Stock Exchange and the Pacific
Exchange under the symbol "HWP." Compaq common stock trades on the New York
Stock Exchange under the symbol "CPQ."


   The following table shows the high and low sales prices per share of HP
common stock and Compaq common stock, each as reported on the New York Stock
Exchange composite transactions tape on (1) August 31, 2001, the last full
trading day preceding public announcement that HP and Compaq had entered into
the merger agreement, and (2) February 4, 2002, the last full trading day for
which high and low sales prices were available as of the date of this joint
proxy statement/prospectus.


   The table also includes the equivalent high and low sales prices per share
of Compaq common stock on those dates. These equivalent high and low sales
prices per share reflect the fluctuating value of the HP common stock that
Compaq shareowners would receive in exchange for each share of Compaq common
stock if the merger was completed on either of these dates, applying the
exchange ratio of 0.6325 of a share of HP common stock for each share of Compaq
common stock.

          CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

   This joint proxy statement/prospectus and the documents incorporated by
reference into this joint proxy statement/prospectus contain forward-looking
statements within the meaning of the Private Securities Litigation Reform Act
of 1995 that involve risks and uncertainties, as well as assumptions, that, if
they never materialize or prove incorrect, could cause the results of HP and
its consolidated subsidiaries, on the one hand, or Compaq and its consolidated
subsidiaries, on the other, to differ materially from those expressed or
implied by such forward-looking statements. All statements other than
statements of historical fact are statements that could be deemed
forward-looking statements, including any projections of earnings, revenues,
synergies, accretion, margins or other financial items; any statements of the
plans, strategies and objectives of management for future operations, including
the execution of integration and restructuring plans and the anticipated timing
of filings, approvals and closings relating to the merger or other planned
acquisitions; any statements concerning proposed new products, services,
developments or industry rankings; any statements regarding future economic
conditions or performance; any statements of belief; and any statements of
assumptions underlying any of the foregoing.

   The risks, uncertainties and assumptions referred to above include the
challenge of managing asset levels, including inventory; the difficulty of
keeping expense growth at modest levels while increasing revenues; the
challenges of integration and restructuring associated with the merger or other
planned acquisitions and the challenges of achieving anticipated synergies; the
possibility that the merger or other planned acquisitions may not close or that
HP, Compaq or other parties to planned acquisitions may be required to modify
some aspects of the acquisition transactions in order to obtain regulatory
approvals; the assumption of maintaining revenues on a combined company basis
following the close of the merger or other planned acquisitions; and other
risks that are described in the section entitled "Risk Factors," which follows
on the next page, and in the documents that are incorporated by reference into
this joint proxy statement/prospectus.

   If any of these risks or uncertainties materializes or any of these
assumptions proves incorrect, results of HP and Compaq could differ materially
from the expectations in these statements. HP and Compaq are not under any
obligation and do not intend to update their respective forward-looking
statements.

                                      22



                                 RISK FACTORS


   HP and Compaq will operate as a combined company in a market environment
that cannot be predicted and that involves significant risks, many of which
will be beyond the combined company's control. In addition to the other
information contained in, or incorporated by reference into, this joint proxy
statement/prospectus, you should carefully consider the risks described below
before deciding how to vote your shares. Additional risks and uncertainties not
presently known to HP and Compaq or that are not currently believed to be
important to you, if they materialize, also may adversely affect the merger and
HP and Compaq as a combined company.


Although HP and Compaq expect that the merger will result in benefits to the
combined company, the combined company may not realize those benefits because
of integration and other challenges.

   The failure of the combined company to meet the challenges involved in
integrating the operations of HP and Compaq successfully or otherwise to
realize any of the anticipated benefits of the merger, including anticipated
cost savings described in this joint proxy statement/prospectus, could
seriously harm the results of operations of the combined company. Realizing the
benefits of the merger will depend in part on the integration of technology,
operations, and personnel. The integration of the companies is a complex,
time-consuming and expensive process that, without proper planning and
implementation, could significantly disrupt the businesses of HP and Compaq.
The challenges involved in this integration include the following:

    .  demonstrating to the customers of HP and to the customers of Compaq that
       the merger will not result in adverse changes in client service
       standards or business focus and helping customers conduct business
       easily with the combined company;

    .  consolidating and rationalizing corporate IT and administrative
       infrastructures;

    .  consolidating manufacturing operations;

    .  combining product offerings;

    .  coordinating sales and marketing efforts to effectively communicate the
       capabilities of the combined company;

    .  coordinating and rationalizing research and development activities to
       enhance introduction of new products and technologies with reduced cost;

    .  preserving distribution, marketing or other important relationships of
       both HP and Compaq and resolving potential conflicts that may arise;


    .  minimizing the diversion of management attention from ongoing business
       concerns and successfully returning more than 450 HP and Compaq managers
       to regular business responsibilities from their integration planning
       activities;


    .  persuading employees that the business cultures of HP and Compaq are
       compatible, maintaining employee morale and retaining key employees;

    .  coordinating and combining overseas operations, relationships and
       facilities, which may be subject to additional constraints imposed by
       local laws and regulations; and

    .  managing a complex integration process shortly after or pending the
       completion of other independent reorganizations by each of HP and Compaq.

   The combined company may not successfully integrate the operations of HP and
Compaq in a timely manner, or at all, and the combined company may not realize
the anticipated benefits or synergies of the merger to the extent, or in the
timeframe, anticipated. The anticipated benefits and synergies relate to cost
savings associated with anticipated restructurings and other operational
efficiencies, greater economies of scale and revenue enhancement opportunities.
However, these anticipated benefits and synergies are based on projections

                                      23



and assumptions, not actual experience, and assume a successful integration. In
addition to the integration risks discussed above, the combined company's
ability to realize these benefits and synergies could be adversely impacted by
practical or legal constraints on its ability to combine operations or
implement workforce reductions.

Compaq shareowners will receive a fixed ratio of 0.6325 of a share of HP common
stock for each share of Compaq common stock regardless of any changes in market
value of Compaq common stock or HP common stock before the completion of the
merger.

   Upon completion of the merger, each share of Compaq common stock will be
converted into the right to receive 0.6325 of a share of HP common stock. The
market values of HP common stock and Compaq common stock have varied since HP
and Compaq entered into the merger agreement and will continue to vary in the
future due to changes in the business, operations or prospects of HP and
Compaq, market assessments of the merger, regulatory considerations, market and
economic considerations, and other factors. The dollar value of HP common stock
that Compaq shareowners will receive upon completion of the merger will depend
on the market value of HP common stock at the time of completion of the merger,
which may be different from, and lower than, the closing price of HP common
stock on the last full trading day preceding public announcement that HP and
Compaq entered into the merger agreement, the last full trading day prior to
the date of this joint proxy statement/prospectus or the date of the special
meetings. Moreover, completion of the merger may occur some time after
shareowner approval has been obtained. There will be no adjustment to the
exchange ratio (except for adjustments to reflect the effect of any stock split
or other recapitalization of HP common stock or Compaq common stock), and the
parties do not have a right to terminate the merger agreement, based upon
changes in the market price of either HP common stock or Compaq common stock.

Some of the directors and executive officers of HP and Compaq have interests
and arrangements that could have affected their decision to support or approve
the merger.


   The interests of some of the directors and executive officers of HP and
Compaq in the merger and their participation in arrangements that are different
from, or are in addition to, those of HP and Compaq shareowners generally could
have affected their decision to support or approve the merger. These interests
include potential retention payments to ten HP executive officers (excluding
Ms. Fiorina) of up to $33.1 million in the aggregate, and potential retention
payments to seven Compaq officers (excluding Mr. Capellas) of up to $22.4
million in the aggregate, with full payment of retention bonuses in both cases
for each eligible officer who remains employed by HP through the second
anniversary of the signing of the merger agreement, assuming that the merger is
completed (in the case of eight of the HP executive officers), or through the
first anniversary of the completion of the merger (in the case of Compaq and
two HP executive officers), and with severance payments being offset by
retention payments. These interests also include employment agreements to be
negotiated promptly following the completion of the merger with six HP officers
and five Compaq officers and the acceleration in connection with the merger of
vesting of certain stock options and restricted stock held by both employees
and directors under the terms of Compaq's equity-based incentive plans. In
addition, Ms. Fiorina and Mr. Capellas both declined the right to participate
in the retention program, but would receive severance payments should their
employment be terminated for certain reasons after the merger. Ms. Fiorina's
potential severance payment equals $8.0 million, pursuant to an agreement which
existed prior to the execution of the merger agreement, and Mr. Capellas'
severance payment equals $14.4 million, pursuant to an agreement which existed
prior to the execution of the merger agreement. Further, upon completion of the
merger, Compaq will make charitable contributions totaling $6.0 million in the
names of its current outside directors, which would not otherwise have been
made until each individual director's death. As a result of these interests,
these directors and officers may be more likely to recommend the proposals
relating to the merger than if they did not have these interests. Please see
the section entitled "Interests of HP and Compaq Directors and Executive
Officers in the Merger" beginning on page 83 of this joint proxy
statement/prospectus.


                                      24



HP and Compaq may be unable to obtain the regulatory approvals required to
complete the merger or, in order to do so, the combined company may be required
to comply with material restrictions or conditions.


   The merger is subject to review by the United States Federal Trade
Commission under the Hart-Scott-Rodino Improvements Act of 1976, and was
subject to review by the European Commission under Council Regulation No.
4064/89 of the European Community and by the Canadian Competition Bureau under
the Competition Act (Canada). Under each of these statutes, HP and Compaq were
required to make pre-merger notification filings and, in the case of the
Hart-Scott-Rodino review, HP and Compaq are awaiting the expiration or early
termination of statutory waiting periods prior to completing the merger. By
September 25, 2001, each of HP and Compaq had completed its initial
Hart-Scott-Rodino filing. On October 25, 2001, each of HP and Compaq received a
request for additional information and other documentary material from the
Federal Trade Commission under the Hart-Scott-Rodino Act in connection with the
merger. This request effectively extends the waiting period for the merger
under the Hart-Scott-Rodino Act until 30 days after both parties substantially
comply with the request for additional information. In practice, complying with
a request for additional information or material under the Hart-Scott-Rodino
Act can take a significant amount of time. HP and Compaq responded to the
request for additional information and continue to cooperate with the FTC in
its investigation. In addition, HP formally notified the European Commission of
the merger by Form CO on December 20, 2001. The merger also may be subject to
review by the governmental authorities of various other jurisdictions under the
antitrust laws of those jurisdictions. On January 31, 2002, the European
Commission issued a formal decision clearing the merger on the basis that it
does not create or strengthen a dominant position as a result of which
effective competition would be significantly impeded in the European Economic
Area (as defined by European Community regulations) or in a substantial part of
it. On December 20, 2001, the Canadian Competition Bureau completed its review
of the proposed merger and found no issues of competitive concern. Other than
the European Commission and the Canadian Competition Bureau, HP and Compaq have
not yet obtained any of the governmental or regulatory approvals required to
complete the merger.


   The reviewing authorities may not permit the merger at all or may impose
restrictions or conditions on the merger that may seriously harm the combined
company if the merger is completed. These conditions could include a complete
or partial license, divestiture, spin-off or the holding separate of assets or
businesses. Either HP or Compaq may refuse to complete the merger if
restrictions or conditions are required by governmental authorities that would
materially adversely impact the combined company's results of operations or the
benefits anticipated to be derived by the combined company. Any delay in the
completion of the merger could diminish the anticipated benefits of the merger
or result in additional transaction costs, loss of revenue or other effects
associated with uncertainty about the transaction.

   HP and Compaq also may agree to restrictions or conditions imposed by
antitrust authorities in order to obtain regulatory approval, and these
restrictions or conditions could harm the combined company's operations. No
additional shareowner approval is expected to be required for any decision by
HP or Compaq, after the special meeting of Compaq shareowners and the special
meeting of HP shareowners, to agree to any terms and conditions necessary to
resolve any regulatory objections to the merger.

   In addition, during or after the statutory waiting periods, and even after
completion of the merger, governmental authorities could seek to block or
challenge the merger as they deem necessary or desirable in the public
interest. In addition, in some jurisdictions, a competitor, customer or other
third party could initiate a private action under the antitrust laws
challenging or seeking to enjoin the merger, before or after it is completed.
HP, Compaq or the combined company may not prevail, or may incur significant
costs, in defending or settling any action under the antitrust laws.

The stock prices and businesses of HP and Compaq may be adversely affected if
the merger is not completed.

   If the merger is not completed, the price of HP common stock and Compaq
common stock may decline to the extent that the current market prices of HP
common stock and Compaq common stock reflect a market

                                      25




assumption that the merger will be completed. In addition, HP's business and
Compaq's operations may be harmed to the extent that customers, suppliers and
others believe that the companies cannot effectively compete in the marketplace
without the merger, or there is customer and employee uncertainty surrounding
the future direction of the product and service offerings and strategy of HP or
Compaq on a standalone basis. In the event the merger is not completed, HP
intends to evaluate its strategic options for addressing the lack of
profitability in certain of its businesses. These strategic options may include
further workforce reductions, but HP currently has no specific plans regarding
workforce reductions in the event that the merger is not completed. Completion
of the merger is subject to several closing conditions, including obtaining
requisite regulatory and shareowner approvals, and HP and Compaq may be unable
to obtain such approvals on a timely basis or at all. Walter B. Hewlett,
Eleanor Hewlett Gimon, Mary Hewlett Jaffe and The William R. Hewlett Revocable
Trust have announced that they intend to vote against the proposal to approve
the issuance of HP common stock in connection with the merger. In addition,
each of the William and Flora Hewlett Foundation and the David and Lucile
Packard Foundation has announced its intention to vote against the proposal to
approve the issuance of HP common stock in connection with the merger.
Mr. Hewlett (co-trustee of The William R. Hewlett Revocable Trust and Chairman
of The William and Flora Hewlett Foundation), Edwin van Bronkhorst (co-trustee
of The William R. Hewlett Revocable Trust and trustee of certain Hewlett family
trusts) and The William R. Hewlett Revocable Trust have filed a preliminary
proxy statement with the Securities and Exchange Commission stating that they
intend to solicit proxies from HP shareowners against the proposal to approve
the issuance of shares of HP common stock in connection with the merger and
have disseminated to HP shareowners soliciting materials encouraging HP
shareowners to vote against the issuance of shares in connection with the
merger. If the merger is not completed, HP would not derive the strategic
benefits expected to result from the merger, such as creating a more complete
and balanced product and services portfolio and providing economies of scale in
businesses such as PCs. HP and Compaq will also be required to pay significant
costs incurred in connection with the merger, including legal, accounting and a
portion of the financial advisory fees, whether or not the merger is completed.
Moreover, under specified circumstances described in the section entitled
"Payment of Termination Fee" beginning on page 104 of this joint proxy
statement/prospectus, HP may be required to pay Compaq a termination fee of
$675 million, or Compaq may be required to pay HP a termination fee of $675
million, in connection with the termination of the merger agreement.


Charges to earnings resulting from the application of the purchase method of
accounting may adversely affect the market value of HP's common stock following
the merger.

   In accordance with United States generally accepted accounting principles,
the combined company will account for the merger using the purchase method of
accounting, which will result in charges to earnings that could have a material
adverse effect on the market value of the common stock of HP following
completion of the merger. Under the purchase method of accounting, the combined
company will allocate the total estimated purchase price to Compaq's net
tangible assets, amortizable intangible assets, intangible assets with
indefinite lives and in-process research and development based on their fair
values as of the date of completion of the merger, and record the excess of the
purchase price over those fair values as goodwill. The portion of the estimated
purchase price allocated to in-process research and development will be
expensed by the combined company in the quarter in which the merger is
completed. The combined company will incur additional depreciation and
amortization expense over the useful lives of certain of the net tangible and
intangible assets acquired in connection with the merger. In addition, to the
extent the value of goodwill or intangible assets with indefinite lives becomes
impaired, the combined company may be required to incur material charges
relating to the impairment of those assets. These depreciation, amortization,
in-process research and development and potential impairment charges could have
a material impact on the combined company's results of operations.

Customer uncertainties related to the merger could adversely affect the
businesses, revenues and gross margins of HP, Compaq and the combined company.

   In response to the announcement of the merger or due to ongoing uncertainty
about the merger, customers of HP or Compaq may delay or defer purchasing
decisions or elect to switch to other suppliers. In particular,

                                      26



prospective customers could be reluctant to purchase the combined company's
products due to uncertainty about the direction of the combined company's
product offerings and willingness to support and service existing products. To
the extent that the merger creates uncertainty among those persons and
organizations contemplating hardware, software or service purchases such that
one large customer, or a significant group of smaller customers, delays, defers
or changes purchases in connection with the planned merger, the revenues of HP,
Compaq or the combined company would be adversely affected. Each of HP and
Compaq continues to believe that, consistent with prior assumptions, there is a
risk of customer loss due to uncertainties relating to the merger. However,
neither HP nor Compaq is aware of any loss of customers, individually or in the
aggregate, as a result of the merger process that would have a material impact
on their respective results of operations. Customer assurances may be made by
HP and Compaq to address their customers' uncertainty about the direction of
the combined company's product and related support offerings which may result
in additional obligations of HP, Compaq or the combined company. Accordingly,
quarterly revenues and net earnings of HP, Compaq or the combined company could
be substantially below expectations of market analysts and a decline in the
companies' respective stock prices could result.

Changes in our credit ratings could adversely affect the costs and expenses of
the combined company.

   Any downgrade in the credit ratings of HP, Compaq or the combined company
associated with the merger could adversely affect the ability of the combined
company to borrow and result in more restrictive borrowing terms, including
increased borrowing costs, more restrictive covenants and the extension of less
open credit. This in turn could affect the combined company's internal cost of
capital estimates and therefore operational decisions. Prior to the
announcement of the merger, HP's senior unsecured debt ratings were Aa3 (with
negative outlook) from Moody's Investors Service and AA- from Standard &
Poor's, and Compaq's senior unsecured debt ratings were Baa2 from Moody's and
BBB from Standard & Poor's. After the merger announcement, Moody's downgraded
HP to A2 (with negative outlook), and Standard & Poor's maintained its AA-
rating but placed HP on CreditWatch with negative implications pending further
review, while Moody's and Standard & Poor's maintained Compaq's rating and
placed it under review for a possible upgrade. Subsequently, in December 2001,
Standard & Poor's placed Compaq on CreditWatch with developing implications.
The ultimate impact of the merger on the combined company's credit ratings,
however, cannot be predicted.

In order to be successful, the combined company must retain and motivate key
employees, which will be more difficult in light of uncertainty regarding the
merger, and failure to do so could seriously harm the combined company.

   In order to be successful, the combined company must retain and motivate
executives and other key employees, including those in managerial, technical,
marketing and information technology support positions. In particular, the
combined company's product generation efforts depend on hiring and retaining
qualified engineers. Attracting and retaining skilled solutions providers in
the IT support business and qualified sales representatives is also critical to
the combined company's future. Experienced management and technical, marketing
and support personnel in the information technology industry are in high demand
and competition for their talents is intense. This is particularly the case in
Silicon Valley, where HP's headquarters and certain key research and
development facilities are located. Employee retention may be a particularly
challenging issue in connection with the merger. Accordingly, the compensation
committee of the HP board of directors (consisting of Philip M. Condit, Sam
Ginn and Walter B. Hewlett) and the human resources committee of the Compaq
board of directors (then consisting of Lawrence T. Babbio, Judith L. Craven and
Kenneth L. Lay), acting on the authority of the HP board of directors and the
Compaq board of directors, respectively, designed and adopted retention
programs to assure the continued dedication of key employees and to provide key
employees with financial incentives to remain with the combined company
following the completion of the merger. A number of factors, however, may
counteract the benefits of these retention programs. In particular, employees
of HP or Compaq may experience uncertainty about their future role with the
combined company until or after strategies with regard to the combined company
are announced or executed. This circumstance may adversely affect the combined
company's ability to attract and retain key management, marketing and technical
personnel. The

                                      27



combined company also must continue to motivate employees and keep them focused
on the strategies and goals of the combined company, which may be particularly
difficult due to the potential distractions of the merger, morale challenges
posed by the separate workforce reductions being implemented by HP and Compaq
and the additional workforce reductions of the combined company anticipated in
connection with the merger.

The economic downturn could adversely affect the revenues, gross margins and
expenses of the combined company.

   The revenues and gross margins of the combined company will depend
significantly on the overall demand for computing and imaging products and
services, particularly in the product and service segments in which it will
compete. Softening demand for the products and services of HP and Compaq caused
by the ongoing economic downturn may result in decreased revenues, earnings
levels or growth rates and problems with the saleability of inventory and
realizability of customer receivables for the combined company. The global
economy has weakened and market conditions continue to be challenging. As a
result, individuals and companies are delaying or reducing expenditures,
including those for information technology. HP and Compaq have observed effects
of the global economic downturn in many areas of their businesses. The downturn
has contributed to reported net revenue declines during the 2001 fiscal year
for both companies. Each of HP and Compaq has also experienced gross margin
declines, reflecting the effect of competitive pressures as well as, in the
case of HP, inventory writedowns and charges associated with the cancellation
of planned production line expansion. HP's selling, general and administrative
expense also was impacted due in part to an increase in bad debt write-offs and
additions to reserves in its receivables portfolio. The economic downturn has
also led to restructuring actions and contributed to writedowns to reflect the
impairment of certain investments in HP's and Compaq's respective investment
portfolios. Further delays or reductions in information technology spending
could have a material adverse effect on demand for the combined company's
products and services, and consequently, its results of operations, prospects
and stock price.

The competitive pressures the combined company will face could harm its
revenues, gross margins and prospects.

   The combined company will encounter aggressive competition from numerous and
varied competitors in all areas of its business, and will compete primarily on
the basis of technology, performance, price, quality, reliability, brand,
distribution, customer service and support. If the combined company fails to
develop new products, services and support, periodically enhance its existing
products, services and support, or otherwise compete successfully, it could
harm its operations and prospects. Further, the combined company may have to
continue to lower the prices of many of its products, services and support to
stay competitive, while at the same time trying to maintain or improve gross
margins. We believe that the merger will result in improvements to gross margin
on a combined company basis, principally through lower procurement costs and
the elimination of redundant headcount. In businesses such as PCs and low-end
servers, the ability to respond to competitive pricing pressures by effectively
managing inventory costs will be particularly important. The merger will also
bring to HP Compaq's low-cost sales model and distribution capabilities in PCs
and low-end servers. However, if the combined company cannot proportionately
decrease its cost structure in response to competitive price pressures, its
gross margins and therefore the profitability of the combined company could be
adversely affected.

If the combined company cannot continue to develop, manufacture and market
innovative products and services rapidly that meet customer requirements for
performance and reliability, it may lose market share and its revenues may
suffer.

   The process of developing new high technology products and services is
complex and uncertain, and failure to anticipate customers' changing needs and
emerging technological trends accurately and to develop or obtain appropriate
intellectual property could significantly harm the combined company's results
of operations. The combined company must make long-term investments and commit
significant resources before knowing whether its predictions will eventually
result in products that the market will accept. After a product is developed,
the

                                      28



combined company must be able to manufacture sufficient volumes quickly and at
low costs. To accomplish this, it must accurately forecast volumes, mix of
products and configurations that meet customer requirements, and it may not
succeed.

If the combined company does not effectively manage the transition from
existing products to new products, its revenues may suffer.

   If the combined company does not make an effective transition from existing
products to new products, its revenues may be seriously harmed. Among the
factors that make a smooth transition from current products to new products
difficult are delays in product development or manufacturing, variations in
product costs, delays in customer purchases of existing products in
anticipation of new product introductions and customer demand for the new
product. The combined company's revenues and gross margins also may suffer due
to the timing of product or service introductions by its suppliers and
competitors. This is especially challenging when a product has a short life
cycle or a competitor introduces a new product just before the combined
company's own product introduction. Furthermore, sales of the combined
company's new products may replace sales of some of the current products of HP
and Compaq, offsetting the benefit of even a successful product introduction.
There may also be overlaps in the current products of HP and Compaq product
portfolios that must be managed in connection with the merger. If the combined
company incurs delays in new product introductions, or does not accurately
estimate the market effects of new product introductions, given the competitive
nature of its industry, future demand for its products and its revenues may be
seriously harmed.

The combined company's revenues and selling, general and administrative
expenses will suffer if it cannot continue to license or enforce the
intellectual property rights on which its business will depend or if third
parties assert that the combined company violates their intellectual property
rights.

   The combined company generally will rely upon patent, copyright, trademark
and trade secret laws in the United States and similar laws in other countries,
and agreements with its employees, customers, partners and other parties, to
establish and maintain its intellectual property rights in technology and
products used in the combined company's operations. However, any of its
intellectual property rights could be challenged, invalidated or circumvented,
or its intellectual property rights may not provide competitive advantages,
which could significantly harm its business. Also, because of the rapid pace of
technological change in the information technology industry, much of the
combined company's business and many of its products will rely on key
technologies developed by third parties, and the combined company may not be
able to obtain or renew licenses and technologies from these third parties at
all or on reasonable terms. Third parties also may claim that the combined
company is infringing upon their intellectual property rights. Even if the
combined company does not believe that its products or business are infringing
upon third parties' intellectual property rights, the claims can be
time-consuming and costly to defend and divert management's attention and
resources away from the combined company's business. Claims of intellectual
property infringement also might require the combined company to enter into
costly settlement or license agreements. If the combined company cannot or does
not license the infringed technology at all or on reasonable terms or
substitute similar technology from another source, its operations could suffer.
In addition, it is possible that as a consequence of the merger, some
intellectual property rights of the combined company may be licensed to a third
party that had not been licensed prior to the creation of the combined company
or that certain restrictions could be imposed on the business of the combined
company that had not been imposed on the business of HP or Compaq prior to the
merger. Consequently, the combined company may lose a competitive advantage
with respect to these intellectual property rights or the combined company may
be required to enter into costly arrangements in order to terminate or limit
these agreements.

If the combined company fails to manage distribution of its products and
services properly, or if its distributors' financial condition or operations
weaken, the combined company's revenues and gross margins could be adversely
affected.

   The combined company will use a variety of different distribution methods to
sell its products and services, including third-party resellers and
distributors and both retail and direct sales to both enterprise accounts and

                                      29



consumers. Since each distribution method has distinct risks and gross margins,
the failure of the combined company to implement the most advantageous balance
in the delivery model for its products and services could adversely affect the
gross margins and therefore profitability of the combined company. For example:

   .   As the combined company continues to increase its commitment to direct
       sales, it could risk alienating channel partners and adversely affecting
       its distribution model.

       Since direct sales made by the combined company may compete with the
       sales made by third-party resellers and distributors, these third-party
       resellers and distributors may elect to use other suppliers that do not
       directly sell their own products. Because not all of the combined
       company's customers will prefer to or seek to purchase directly, any
       increase by the combined company of its commitment to direct sales in
       order to increase its gross margins could alienate some of its channel
       partners. As a result, the combined company may lose some of its
       customers who purchase from third-party resellers or distributors.
       Moreover, uncertainty regarding the merger may cause some of the
       combined company's distributors to strengthen relationships with other
       vendors.

   .   Some of the combined company's wholesale and retail distributors may be
       unable to withstand changes in business conditions.

       Some of the combined company's wholesale and retail distributors may
       have insufficient financial resources and may not be able to withstand
       changes in business conditions, including the recent economic downturn
       and changes that may result from the merger. Revenues from indirect
       sales by the combined company could suffer if its distributors'
       financial condition or operations weaken.

   .   Inventory management of the combined company will be complex as the
       combined company will continue to sell a significant mix of products
       through distributors.

       The combined company must manage inventory effectively, particularly
       with respect to sales to distributors. Distributors may increase orders
       during periods of product shortages, cancel orders if their inventory is
       too high, or delay orders in anticipation of new products. Distributors
       also may adjust their orders in response to the supply of the combined
       company's products and the products of its competitors that are
       available to the distributor and seasonal fluctuations in end-user
       demand. If the combined company has excess inventory, it may have to
       reduce its prices and write down inventory, which in turn could result
       in lower gross margins.

The combined company will depend on third-party suppliers and its revenues and
gross margins could be adversely affected if it fails to receive timely
delivery of quality components or if it fails to manage inventory levels
properly.

   The manufacturing operations of the combined company will depend on the
combined company's ability to anticipate its needs for components and products
and its suppliers' ability to deliver quality components and products in time
to meet critical manufacturing and distribution schedules. Given the wide
variety of systems, products and services that the combined company will offer
and the large number of its suppliers and contract manufacturers that are
dispersed across the globe, problems could arise in planning production and
managing inventory levels that could seriously harm the combined company. Among
the problems that could arise are component shortages, excess supply and risks
related to fixed-price contracts that would require the combined company to pay
more than the open market price.

   .   Supply shortages.  The combined company occasionally may experience a
       short supply of certain component parts as a result of strong demand in
       the industry for those parts or problems experienced by suppliers. If
       shortages or delays persist, the price of these components may increase,
       or the components may not be available at all. The combined company may
       not be able to secure enough components at reasonable prices and of
       acceptable quality to build new products in a timely manner in the
       quantities and configurations needed. Accordingly, the revenues and
       gross margins of the combined company could suffer until other sources
       can be developed.

                                      30



   .   Oversupply.  In order to secure components for the production of new
       products, at times the combined company may make advance payments to
       suppliers, or it may enter into non-cancelable purchase commitments with
       vendors. If the combined company fails to anticipate customer demand
       properly, a temporary oversupply of parts could result in excess or
       obsolete components which could adversely affect the combined company's
       gross margins.

   .   Long-term pricing commitments.  As a result of binding price or purchase
       commitments with vendors, the combined company may be obligated to
       purchase components at prices that are higher than those available in
       the current market. In the event the combined company becomes committed
       to purchase components for prices in excess of the current market price,
       it may be at a disadvantage to competitors who have access to components
       at lower prices, and the combined company's gross margins could suffer.

Due to the international nature of the combined company's business, political
or economic changes could harm its future revenues, costs and expenses and
financial condition.

   At the time of the completion of the merger, sales outside the United States
will make up more than half of the combined company's revenues. The future
revenues, costs, expenses of the combined company could be adversely affected
by a variety of international factors, including:

   .   changes in a country's or region's political or economic conditions;

   .   longer accounts receivable cycles;

   .   trade protection measures;

   .   overlap of different corporate structures;

   .   unexpected changes in regulatory requirements;

   .   differing technology standards and/or customer requirements;

   .   import or export licensing requirements, which could affect the combined
       company's ability to obtain favorable terms for components or lead to
       penalties or restrictions;

   .   problems caused by the conversion of various European currencies to the
       Euro and macroeconomic dislocations that may result; and

   .   natural disasters.

   A portion of the combined company's product and component manufacturing,
along with key suppliers, also will be located outside of the United States,
and also could be disrupted by some of the international factors described
above. In particular, each of HP and Compaq, along with most other PC vendors,
has engaged manufacturers in Taiwan for the production of notebook computers.
In 1999, Taiwan suffered a major earthquake, and in 2000 it suffered a typhoon,
both of which resulted in temporary communications and supply disruptions. In
addition, the combined company will procure components from Japan, which also
suffers from earthquakes periodically. Moreover, HP is in the process of
acquiring Indigo, N.V., which has research and development and manufacturing
operations located in Israel, which may be more subject to disruptions in light
of recent world events.

The combined company will be exposed to foreign currency exchange rate and
interest rate risks that could adversely affect the revenues and gross margins
of the combined company.

   The combined company will be exposed to foreign currency exchange rate risk
that will be inherent in its sales commitments, anticipated sales, and assets
and liabilities that are denominated in currencies other than the United States
dollar. The combined company also will be exposed to interest rate risk
inherent in its debt and investment portfolios. Failure to sufficiently hedge
or otherwise manage foreign currency risks properly could adversely affect the
combined company's revenues and gross margins.

                                      31



Impairment of investment and financing portfolios could harm the combined
company's net earnings.

   The combined company will have an investment portfolio that will include
minority equity and debt investments and financing for the purchase of the
combined company's products and services. In most cases, the combined company
will not attempt to reduce or eliminate its market exposure on these
investments and may incur losses related to the impairment of these investments
and therefore charges to net earnings. Some of the combined company's
investments will be in publicly and privately held companies that are still in
the start-up or development stage, which have inherent risks because the
markets for the technologies or products they have under development are
typically in the early stages and may never develop. Furthermore, the values of
the combined company's investments in publicly-traded companies will be subject
to significant market price volatility. The combined company's investments in
technology companies often will be coupled with a strategic commercial
relationship. The combined company's commercial agreements with these companies
may not be sufficient to allow it to obtain and integrate such products or
technology into its technology or product lines or otherwise benefit from the
relationship, and these companies may be subsequently acquired by third
parties, including competitors of the combined company. Moreover, due to the
economic downturn and difficulties that may be faced by some of the companies
to which HP, Compaq or the combined company has supplied financing, the
combined company's investment portfolio could be further impaired.

In order to manage their portfolios of products and technology and further
their competitive objectives, HP and Compaq must successfully complete
acquisitions and alliances that enhance their strategic businesses and product
lines and divest non-strategic businesses and product lines.

   As part of their business strategies, HP and Compaq frequently engage in
discussions with third parties regarding, and enter into agreements relating
to, possible acquisitions, strategic alliances, joint ventures and divestitures
in order to manage their respective product and technology portfolios and
further strategic objectives. It is expected that the combined company will
engage in similar transactions. In order to pursue this strategy successfully,
the combined company must identify suitable acquisition, alliance or
divestiture candidates, complete these transactions, some of which may be large
and complex, and integrate acquired companies. Integration and other risks of
acquisitions and strategic alliances can be more pronounced for larger and more
complicated transactions, or if multiple acquisitions are pursued
simultaneously. The integration of HP and Compaq may make the completion and
integration of subsequent acquisitions more difficult. However, if the combined
company fails to identify and complete these transactions, it may be required
to expend resources to internally develop products and technology or may be at
a competitive disadvantage or may be adversely affected by negative market
perceptions, which may have a material effect on the revenues and selling,
general and administrative expenses of the combined company taken as a whole.

   In addition to the pending Compaq transaction, HP currently has pending a
proposed acquisition of Indigo N.V., a leading commercial and industrial
printing systems company. In 2001, HP completed acquisitions of StorageApps,
Inc., a provider of storage virtualization solutions, and Bluestone Software,
Inc., which became part of HP's middleware division. Compaq acquired assets
from InaCom Corp. to add custom configuration capabilities and direct
fulfillment logistics in 2000. These and other acquisitions and strategic
alliances may require the combined company to integrate with a different
company culture, management team and business infrastructure and otherwise
manage integration risks. Even if an acquisition or alliance is successfully
integrated, the combined company may not receive the expected benefits of the
transaction. Managing acquisitions, alliances and divestitures requires varying
levels of management resources, which may divert the combined company's
attention from other business operations. These transactions also may result in
significant costs and expenses and charges to earnings. As a result, any
completed, pending or future transactions may contribute to the combined
company's financial results differing from the investment community's
expectations in a given quarter.

                                      32



Terrorist acts and acts of war may seriously harm the combined company's
business and revenues, costs and expenses and financial condition.

   Terrorist acts or acts of war (wherever located around the world) may cause
damage or disruption to the combined company, its employees, facilities,
partners, suppliers, distributors and resellers, and customers, which could
significantly impact the combined company's revenues, costs and expenses and
financial condition. The terrorist attacks that took place in the United States
on September 11, 2001 were unprecedented events that have created many economic
and political uncertainties, some of which may materially harm the combined
company's business and results of operations. The long-term effects on the
combined company of the September 11, 2001 attacks are unknown. The potential
for future terrorist attacks, the national and international responses to
terrorist attacks, and other acts of war or hostility have created many
economic and political uncertainties, which could adversely affect the business
and results of operations of HP, Compaq or the combined company in ways that
cannot presently be predicted. In addition, as major multi-national companies
with headquarters and significant operations located in the United States, any
of HP, Compaq or the combined company may be impacted by actions against the
United States. The combined company will be predominantly uninsured for losses
and interruptions caused by terrorist acts and acts of war.

Business disruptions could seriously harm the future revenues and financial
condition and increase the costs and expenses of the combined company.

   The combined company's worldwide operations could be subject to natural
disasters and other business disruptions, which could seriously harm its
revenues and financial condition and increase its costs and expenses. The
corporate headquarters of the combined company, a portion of its research and
development activities, other critical business operations and some of its
suppliers will be located in California, near major earthquake faults. The
ultimate impact on the combined company, its significant suppliers and its
general infrastructure of being located near major earthquake faults is
unknown, but the combined company's revenues, financial condition and costs and
expenses could be significantly impacted in the event of a major earthquake. In
addition, some areas, including California, have experienced, and may continue
to experience, ongoing power shortages, which have resulted in "rolling
blackouts." These blackouts could cause disruptions to the operations of the
combined company or the operations of its suppliers, distributors and
resellers, or customers. The combined company will be predominantly uninsured
for losses and interruptions caused by earthquakes, power outages and other
natural disasters.

Unforeseen environmental costs could impact the future net earnings of the
combined company.

   Some of the combined company's operations will use substances regulated
under various federal, state and international laws governing the environment.
The combined company could be subject to liability for remediation if it does
not handle these substances in compliance with applicable laws. It will be the
combined company's policy to apply strict standards for environmental
protection to sites inside and outside the United States, even when not subject
to local government regulations. The combined company will record a liability
for environmental remediation and related costs when it considers the costs to
be probable and the amount of the costs can be reasonably estimated. Neither HP
nor Compaq has incurred environmental costs that are presently material to it,
and neither HP nor Compaq is presently subject to known environmental
liabilities that it expects to be material.

The revenues and profitability of the operations of HP and Compaq have
historically varied.

   The revenues and profit margins of HP and Compaq vary among their respective
products, customer groups and geographic markets. The revenue mix of the
combined company will be different than the revenue mix of either HP or Compaq
alone, particularly with respect to the proportion contributed by personal
computers and printing and imaging devices and supplies. Overall profitability
in any given period is dependent partially on the product, customer and
geographic mix reflected in that period's net revenue, and therefore revenue
and gross

                                      33



margin trends cannot be reliably predicted. Actual trends may cause the
combined company to adjust its operations, which could cause period-to-period
fluctuations in the combined company's results of operations.

Failure to successfully execute planned cost reductions could result in total
costs and expenses for the combined company that are greater than expected.

   Historically, each of HP and Compaq has separately undertaken restructuring
plans to bring operational expenses to appropriate levels for each of its
businesses, while simultaneously implementing extensive new company-wide
expense-control programs. In addition to the previously announced workforce
reductions of the separate companies, the combined company may have additional
workforce reductions. The planned workforce reductions are expected to involve
approximately 15,000 employees of the combined company worldwide, representing
approximately 10% of the combined company's workforce, and workforce reductions
would also be expected if the proposed merger were not completed. Significant
risks associated with these actions that may impair the ability of the combined
company to achieve anticipated cost reductions or that may otherwise harm its
integration efforts or business include delays in implementation of anticipated
reductions in force in highly regulated locations outside of the United States,
particularly in Europe and Asia, redundancies among restructuring programs, and
the failure to meet operational targets due to the loss of employees or
decreases in employee morale.

HP's stock price has historically fluctuated and may continue to fluctuate.

   HP's stock price, like that of other technology companies, can be volatile.
Some of the factors that can affect its stock price are:

    .  the announcement of new products, services or technological innovations
       by HP or its competitors;

    .  quarterly increases or decreases in HP's revenue or earnings;

    .  changes in quarterly revenue or earnings estimates by the investment
       community; and

    .  speculation in the press or investment community about HP's strategic
       position, financial condition, results of operations, business or
       significant transactions.

   General market conditions and domestic or international macroeconomic and
geopolitical factors unrelated to HP's performance may also affect HP's stock
price. For these reasons, investors should not rely on recent trends to predict
future stock prices or financial results. In addition, following periods of
volatility in a company's securities, securities class action litigation
against a company is sometimes instituted. This type of litigation could result
in substantial costs and the diversion of management time and resources. HP
anticipates that it will continue to face similar risks associated with stock
price volatility following the merger.

The effective tax rate of the combined company is uncertain.

   The impact of the merger on the overall effective tax rate of the combined
company is uncertain. Although the combined company will attempt to optimize
its overall effective tax rate, it is impossible to predict the effective tax
rate of the combined company accurately. The combination of the operations of
HP and Compaq may result in an overall effective tax rate for the combined
company that is higher than HP's currently reported tax rate, and it is
possible that the combined effective tax rate of HP and Compaq as a combined
company may exceed the weighted average of the pre-merger tax rates of HP and
Compaq.

                                      34



Some anti-takeover provisions contained in HP's certificate of incorporation,
bylaws and shareowner rights plan, as well as provisions of Delaware law, could
impair a takeover attempt.

   HP has provisions in its certificate of incorporation and bylaws, each of
which could have the effect of rendering more difficult or discouraging an
acquisition deemed undesirable by the HP board of directors. These include
provisions:

    .  authorizing blank check preferred stock, which could be issued with
       voting, liquidation, dividend and other rights superior to its common
       stock;

    .  limiting the liability of, and providing indemnification to, directors
       and officers;

    .  limiting the ability of HP shareowners to call special meetings;

    .  requiring advance notice of shareowner proposals for business to be
       conducted at annual meetings of HP shareowners and for nominations of
       candidates for election to the HP board of directors;

    .  controlling the procedures for conduct of board and shareowner meetings
       and election and removal of directors; and

    .  specifying that shareowners may take action only at a duly called annual
       or special meeting of shareowners.

These provisions, alone or together, could deter or delay hostile takeovers,
proxy contests and changes in control or management of HP.

   In addition, HP has adopted a shareowner rights plan. The rights are not
intended to prevent a takeover of HP. However, the rights may have the effect
of rendering more difficult or discouraging an acquisition of HP deemed
undesirable by the HP board of directors. The rights will cause substantial
dilution to a person or group that attempts to acquire HP on terms or in a
manner not approved by the HP board of directors, except pursuant to an offer
conditioned upon redemption of the rights.

   As a Delaware corporation, HP is also subject to provisions of Delaware law,
including Section 203 of the Delaware General Corporation law, which prevents
some shareowners from engaging in certain business combinations without
approval of the holders of substantially all of HP's outstanding common stock.

   Any provision of HP's certificate of incorporation or bylaws, HP's
shareowner rights plan or Delaware law that has the effect of delaying or
deterring a change in control could limit the opportunity for HP shareowners
(including former Compaq shareowners who become HP shareowners upon completion
of the merger) to receive a premium for their shares of HP common stock, and
could also affect the price that some investors are willing to pay for HP
common stock.

                                      35



                     THE SPECIAL MEETING OF HP SHAREOWNERS

Date, Time and Place


   The HP special meeting will be held at 8:00 a.m., local time, on March 19,
2002 at The Flint Center, 21250 Stevens Creek Boulevard, Cupertino, California.



   Check-in will begin at 6:30 a.m. and HP shareowners should allow ample time
for the check-in procedures.


Item of Business

   At the HP special meeting, HP shareowners will be asked to consider and vote
upon a proposal to approve the issuance of shares of HP common stock in
connection with the merger as more fully described in this joint proxy
statement/prospectus. HP currently does not contemplate that any other matters
will be presented at the HP special meeting.

Recommendation of the HP Board of Directors

   After careful consideration, the HP board of directors unanimously
determined that the merger is advisable, and is fair to and in the best
interests of HP and its shareowners, and unanimously approved the merger
agreement. The HP board of directors recommends that the HP shareowners vote
"FOR" the proposal to approve the issuance of shares of HP common stock in
connection with the merger.

Admission to the Special Meeting

   Only HP shareowners, including joint holders, as of the close of business on
January 28, 2002, and other persons holding valid proxies for the special
meeting are entitled to attend the HP special meeting. HP shareowners and their
proxies should be prepared to present photo identification. In addition, HP
shareowners who are record holders or hold their shares through HP's TAXCAP or
Stock Ownership Plan will have their ownership verified against the list of
record holders or plan participants as of the record date prior to being
admitted to the meeting. HP shareowners who are not record holders but hold
shares through a broker or nominee (i.e., in street name) should provide proof
of beneficial ownership on the record date, such as their most recent account
statement prior to January 28, 2002, or other similar evidence of ownership.
Anyone who does not provide photo identification or comply with the other
procedures outlined above upon request will not be admitted to the special
meeting.

Method of Voting; Record Date; Stock Entitled to Vote; Quorum

   HP shareowners are being asked to vote both shares held directly in their
name as shareowners of record and any shares they hold in street name as
beneficial owners. Shares held in street name are shares held in a stock
brokerage account or shares held by a bank or other nominee.

   The method of voting differs for shares held as a record holder and shares
held in street name. Record holders will receive proxy cards. Holders of shares
in street name will receive voting instruction cards in order to instruct their
brokers or nominees how to vote.


   WHITE proxy cards and voting instruction cards are being solicited on behalf
of the HP board of directors from HP shareowners in favor of the proposal to
approve the issuance of shares of HP common stock in connection with the merger.


   Shareowners may receive more than one set of voting materials, including
multiple copies of this joint proxy statement/prospectus and multiple proxy
cards or voting instruction cards. For example, shareowners who hold shares in
more than one brokerage account may receive a separate WHITE voting instruction
card for each

                                      36




brokerage account in which shares are held. Shareowners of record whose shares
are registered in more than one name, and shareowners whose shares are held in
HP's TAXCAP or Stock Ownership Plan in addition to other holdings, will receive
more than one WHITE proxy card. In addition, Compaq is also soliciting votes
for its special meeting in order to approve and adopt the merger agreement and
approve the merger, and shareowners who own shares of both HP and Compaq will
also receive a WHITE proxy or voting instruction card from Compaq. Please note
that a vote for the issuance of shares in connection with the merger for the HP
special meeting will not constitute a vote for the proposal to approve and
adopt the merger agreement and approve the merger for the Compaq special
meeting, and vice versa. Therefore, the HP board of directors urges HP
shareowners to complete, sign, date and return each WHITE proxy card and voting
instruction card for the HP special meeting they receive.



   HP shareowners may also receive a green proxy or voting instruction card
which is being solicited by a dissident group against the HP proposal to issue
shares of HP common stock in connection with the merger. The HP board of
directors urges HP shareowners to discard any green proxy or voting instruction
cards sent by the dissident group. HP shareowners who have previously signed a
green proxy or voting instruction card sent by the dissident group are urged by
the HP board of directors to sign, date and promptly mail the enclosed WHITE
proxy card or voting instruction card for the HP special meeting, which will
revoke any earlier dated proxy or voting instruction cards solicited by the
dissident group. It is not necessary to contact the dissident group for the
revocation to be effective.


   Only shareowners of HP at the close of business on January 28, 2002, the
record date for the HP special meeting, are entitled to receive notice of, and
vote at, the HP special meeting. On the record date,
approximately 1,941,391,000 shares of HP common stock were issued and
outstanding. Shareowners of HP common stock on the record date are each
entitled to one vote per share of HP common stock on the proposal to approve
the issuance of shares of HP common stock in connection with the merger.

   A quorum of shareowners is necessary to have a valid meeting of HP
shareowners. A majority of the shares of HP common stock issued and outstanding
and entitled to vote on the record date must be present in person or by proxy
at the HP special meeting in order for a quorum to be established.


   Abstentions and broker "non-votes" count as present for establishing the
quorum described above. A broker "non-vote" may occur on an item when a broker
is not permitted to vote on that item without instructions from the beneficial
owner of the shares. Shares held by HP in its treasury do not count toward the
quorum.


Adjournment and Postponement


   HP's bylaws provide that any adjournment or postponement of the HP special
meeting may be made at any time by the chairman of the meeting or a vote of
shareowners holding a majority of shares of HP common stock represented at the
HP special meeting, either in person or by proxy, whether or not a quorum
exists, without further notice other than by an announcement made at the
special meeting. HP's bylaws also provide that no matter may be brought before
a special meeting which is not stated in the notice of the special meeting.


Required Vote

   Under the applicable rules of the New York Stock Exchange, the issuance of
shares of HP common stock in connection with the merger requires an affirmative
vote of a majority of the votes cast at the HP special meeting, provided that
the total vote cast on the proposal represents over 50% of all shares of HP
common stock entitled to vote on the proposal.


   Under the applicable rules of the New York Stock Exchange, brokers and other
nominees are prohibited from giving a proxy to vote their customers' shares
with respect to the proposal to be voted on at the HP special meeting in the
absence of instructions from their customers. For purposes of determining
whether HP has


                                      37



received the affirmative vote of a majority of the votes cast at the HP special
meeting, broker "non-votes" and abstentions will not be considered votes cast
and will therefore have no effect on the outcome of the proposal.

   For purposes of determining whether the total vote cast represents over 50%
of all shares of HP common stock entitled to vote on the proposal, broker
"non-votes" and abstentions will be considered entitled to vote and will
therefore make it more difficult to meet this requirement. If the total vote
cast on the proposal represents over 50% of all shares of HP common stock
entitled to vote on the proposal, these broker "non-votes" and abstentions
would have no effect on the outcome of the proposal.

Share Ownership of HP Directors and Executive Officers

   At the close of business on the record date for the HP special meeting,
directors and executive officers of HP and their affiliates beneficially owned
and were entitled to vote approximately 4.9% of the 1,941,391,000 shares of HP
common stock outstanding on that date.

Voting Procedures

   Submitting Proxies or Voting Instructions



   Whether HP shareowners hold shares of HP common stock directly as
shareowners of record or in street name, HP shareowners may direct the voting
of their shares without attending the HP special meeting. HP shareowners may
vote by granting proxies or, for shares held in street name, by submitting
voting instructions to their brokers or nominees.

   Record holders of shares of HP common stock may submit proxies by
completing, signing and dating their WHITE proxy cards for the HP special
meeting and mailing them in the accompanying pre-addressed envelopes. HP
shareowners who hold shares in street name may vote by mail by completing,
signing and dating the WHITE voting instruction cards for the HP special
meeting provided by their brokers or nominees and mailing them in the
accompanying pre-addressed envelopes.


   If HP shareowners of record do not include instructions on how to vote their
properly signed WHITE proxy cards for the HP special meeting, their shares will
be voted "for" the proposal to approve the issuance of shares of HP common
stock in connection with the merger, and in the discretion of the proxy holders
on any other business that may properly come before the HP special meeting or
any adjournment or postponement thereof.



   If HP shareowners holding shares of HP common stock in street name do not
provide voting instructions, their shares will not be considered to be votes
cast on the proposal. However, any HP shares held in HP's TAXCAP plan and
Agilent Technologies, Inc.'s 401(k) plan, respectively, as to which voting
instructions are not provided will be voted in proportion to the way the other
participants of HP's TAXCAP plan and Agilent's 401(k) plan, respectively, vote
their shares.



   Shareowners of record of HP common stock may also vote in person at the HP
special meeting by submitting their proxy cards or by filling out a ballot at
the special meeting.



   If shares of HP common stock are held by HP shareowners in street name,
those HP shareowners may not vote their shares in person at the HP special
meeting unless they bring a signed proxy from the record holder giving them the
right to vote their shares and fill out a ballot at the special meeting.


                                      38



   Revoking Proxies or Voting Instructions

   HP shareowners may change their votes at any time prior to the vote at the
HP special meeting. HP shareowners of record may change their votes by granting
new proxies bearing a later date (which automatically revoke the earlier
proxies) or by attending the HP special meeting and voting in person.
Attendance at the HP special meeting will not cause previously granted proxies
to be revoked, unless HP shareowners specifically so request. For shares held
in street name, HP shareowners may change their votes by submitting new voting
instructions to their brokers or nominees or by attending the HP special
meeting and voting in person, provided that they have obtained a signed proxy
from the record holder giving them the right to vote their shares.

   Proxy Solicitation

   HP is soliciting proxies for the HP special meeting from HP shareowners and
Compaq is soliciting proxies for the Compaq special meeting from its
shareowners. Each company will share equally the cost of printing and filing
this joint proxy statement/prospectus and the registration statement on Form
S-4, of which it forms a part, that has been filed by HP with the Securities
and Exchange Commission.

   Other than the costs shared with Compaq, the cost of soliciting proxies from
HP shareowners will be paid by HP.

   In addition to the mailing of these proxy materials, the solicitation of
proxies or votes may be made in person or by telephone, facsimile, telegram or
electronic means by HP's directors, officers and employees, who will not
receive any additional compensation for such solicitation activities.

   HP has retained Georgeson Shareholder and Innisfree M&A Incorporated to
assist it in the solicitation of proxies. HP has incurred initial fees of
$135,000 payable to Georgeson Shareholder and Innisfree together, and has
agreed to pay additional fees which generally become payable following the
mailing of HP's definitive proxy materials of up to an additional $1,150,000,
plus monthly consulting fees of $25,000, for both firms together. HP has also
agreed to reimburse such firms for out-of-pocket expenses for these services.
HP has agreed to indemnify Georgeson and Innisfree against any liabilities and
expenses arising out of their respective engagements, except for liabilities
and expenses resulting from their respective negligence or misconduct. Upon
request, HP also will reimburse brokerage houses and other custodians, nominees
and fiduciaries for their reasonable out-of-pocket expenses for forwarding
proxy and solicitation materials to HP shareowners.

   Contact for Questions and Assistance in Voting

Confidential Voting Policy

   It is HP's policy that proxy instructions, ballots and voting tabulations
that identify individual HP shareowners are handled in a manner that protects
voting privacy. HP shareowner votes will not be disclosed within HP or to
Compaq or third parties, except (1) as necessary to meet applicable legal
requirements, (2) to allow for the tabulation of votes and certification of the
vote, or (3) to facilitate a successful proxy solicitation. Occasionally, HP
shareowners provide written comments on their proxy cards, which are then
forwarded to HP management.

Other Matters


   HP is not aware of any other business to be acted upon at the HP special
meeting. HP's bylaws also provide that no matter may be brought before a
special meeting which is not stated in the notice of the special meeting. If,
however, other matters are properly brought before the HP special meeting or
any adjournment or postponement of the HP special meeting, the persons named as
proxy holders, Carleton S. Fiorina and Ann O. Baskins, will have discretion to
act on those matters, or to adjourn or postpone the HP special meeting.

                   THE SPECIAL MEETING OF COMPAQ SHAREOWNERS

Date, Time and Place


   The Compaq special meeting will be held at 2:00 p.m., local time, on March
20, 2002 at The Wyndham Greenspoint Hotel, Raphael Ballroom, 12400 Greenspoint
Drive, Houston, Texas.


Items of Business

   At the Compaq special meeting, Compaq shareowners will be asked to consider
and vote upon the proposal to approve and adopt the merger agreement and
approve the merger. Compaq shareowners also will consider any other business
that may properly come before the Compaq special meeting or any adjournment or
postponement of the Compaq special meeting. Compaq currently does not
contemplate that any other matters will be considered at the Compaq special
meeting.

Recommendation of the Compaq Board of Directors

   After careful consideration, the Compaq board of directors unanimously
determined that the merger is advisable, and is fair to and in the best
interests of Compaq and its shareowners and unanimously approved the merger
agreement. The Compaq board of directors recommends that Compaq shareowners
vote "FOR" the proposal to approve and adopt the merger agreement and approve
the merger.

Admission to the Special Meeting

   Only Compaq shareowners, including joint holders, as of the close of
business on January 28, 2002 and other persons holding valid proxies for the
special meeting are entitled to attend the special meeting. All shareowners and
their proxies should be prepared to present photo identification. In addition,
if you are a record holder, your name is subject to verification against the
list of record holders on the record date prior to being admitted to the
meeting. Compaq shareowners who are not record holders but hold shares through
a broker or nominee (i.e., in street name) should be prepared to provide proof
of beneficial ownership on the record date, such as a recent account statement
prior to January 28, 2002, or similar evidence of ownership. If you do not
provide photo identification or comply with the other procedures outlined above
upon request, you will not be admitted to the special meeting.

Method of Voting; Record Date; Stock Entitled to Vote; Quorum

   Compaq shareowners are being asked to vote both shares held directly in
their name as shareowners of record and any shares they hold in street name as
beneficial owners. Shares held in street name are shares held in a stock
brokerage account or shares held by a bank or other nominee.

   The method of voting differs for shares held as a record holder and shares
held in street name. Record holders will receive proxy cards. Holders of shares
in street name will receive voting instruction cards in order to instruct their
brokers or nominees how to vote.

   WHITE proxy cards and voting instruction cards are being solicited on behalf
of the Compaq board of directors from Compaq shareowners in favor of the
proposal to approve and adopt the merger agreement and approve the merger.

   Shareowners may receive more than one set of voting materials, including
multiple copies of this joint proxy statement/prospectus and multiple proxy
cards or voting instruction cards. For example, shareowners who hold shares in
more than one brokerage account will receive a separate WHITE voting
instruction card for each brokerage account in which shares are held.
Shareowners of record whose shares are registered in more than one name will
receive more than one WHITE proxy card. In addition, HP is also soliciting
votes for its special

                                      41



meeting in order to approve the issuance of shares of HP common stock in
connection with the merger, and shareowners who own shares of both HP and
Compaq will also receive a WHITE proxy or voting instruction card from HP.
Please note that a vote to approve and adopt the merger agreement and approve
the merger for the Compaq special meeting will not constitute a vote for the
proposal to approve the issuance of HP common stock in connection with the
merger and vice versa. Therefore, Compaq shareowners should complete, sign,
date and return each WHITE proxy card and voting instruction card they receive.

   Only shareowners of record of Compaq at the close of business on January 28,
2002, the record date for the Compaq special meeting, are entitled to receive
notice of, and have the right to vote at, the Compaq special meeting. On the
record date, approximately 1,704,636,342 shares of Compaq common stock were
issued and outstanding. Shareowners of record of Compaq on the record date are
entitled to one vote per share of Compaq common stock on the proposal to
approve and adopt the merger agreement and approve the merger.

   A quorum of shareowners is necessary to have a valid meeting of Compaq
shareowners. A majority of the shares of Compaq common stock issued and
outstanding and entitled to vote on the record date must be present in person
or by proxy at the Compaq special meeting in order for a quorum to be
established.

   Abstentions and broker "non-votes" count as present for establishing a
quorum. A broker "non-vote" occurs on an item when a broker is not permitted to
vote on that item without instructions from the beneficial owner of the shares
and no instructions are given. Shares held by Compaq in its treasury do not
count toward establishing a quorum.

Adjournment and Postponement


   Compaq shareowners may be asked to vote upon a proposal to adjourn or
postpone the Compaq special meeting.


Required Vote

   Approval and adoption of the merger agreement and approval of the merger
will require the affirmative vote of the holders of a majority of the shares of
Compaq common stock outstanding on the record date. Under applicable Delaware
law, for the purpose of determining whether the proposal to approve and adopt
the merger agreement and approve the merger has received the requisite number
of affirmative votes, abstentions will be counted and have the same effect as a
vote "against" the proposal. In addition, failing to vote will have the same
effect as a vote "against" the proposal. Under the applicable rules of the New
York Stock Exchange, a broker or nominee who holds shares for customers, who
are the beneficial owners of those shares, are prohibited from giving a proxy
to vote those customers' shares with respect to the proposal to be voted on at
the Compaq special meeting without instructions from the customer. Shares held
by a broker or nominee which are not voted because the customer has not
provided instructions to the broker or nominee will have the same effect as a
vote "against" the proposal.

Share Ownership of Compaq Directors and Executive Officers

   At the close of business on the record date for the Compaq special meeting,
directors and executive officers of Compaq and their affiliates beneficially
owned and were entitled to vote less than one percent of the 1,704,636,342
shares of Compaq common stock outstanding on that date.

                                      42



Voting Procedures

   Submitting Proxies or Voting Instructions

   Compaq shareowners of record may vote their shares by attending the Compaq
special meeting and voting their shares in person at the special meeting, or by
completing their WHITE proxy cards and signing, dating and mailing them in the
enclosed self-addressed envelopes. If a WHITE proxy card is signed by a
shareowner of record of Compaq and returned without voting instructions, the
shares represented by the proxy will be voted "FOR" the proposal to approve and
adopt the merger agreement and approve the merger, and in the discretion of
Jeff Clarke and Thomas C. Siekman, as the proxy holders, on any other business
that may properly come before the Compaq special meeting or any adjournment or
postponement of the Compaq special meeting.

   Because Delaware, the state in which Compaq is incorporated, permits
electronic submission of proxies, Compaq shareowners who are shareowners of
record have the option to submit their proxies by using the telephone or the
Internet. The telephone and Internet voting procedures are designed to
authenticate votes cast by use of a personal identification number. These
procedures allow Compaq shareowners to appoint a proxy to vote their shares of
Compaq common stock and to confirm that their instructions have been properly
recorded. Instructions for voting by using the telephone or the Internet are
printed on the proxy card for Compaq shareowners of record.

   Compaq shareowners whose shares are held in the name of a broker or nominee
must either direct the record holder of their shares as to how to vote their
shares of Compaq common stock or obtain a proxy from the record holder to vote
at the Compaq special meeting. Beneficial holders of Compaq common stock should
check the WHITE voting instruction cards used by their brokers or nominees to
see if they may vote by using the telephone or the Internet.

   Revoking Proxies or Voting Instructions

   Compaq shareowners of record may revoke their proxies at any time prior to
the time their proxies are voted at the Compaq special meeting. Proxies may be
revoked by written notice to the corporate secretary of Compaq, by a
later-dated proxy signed and returned by mail, or by attending the Compaq
special meeting and voting in person. Compaq shareowners of record may also
revoke proxies by a later-dated proxy using the telephone or Internet voting
procedures described on their WHITE proxy cards.

   Compaq shareowners whose shares are held in the name of a broker or nominee
may change their votes by submitting new WHITE voting instructions to their
brokers or nominees. Those Compaq shareowners may not vote their shares in
person at the Compaq special meeting unless they obtain a signed proxy from the
record holder giving them the right to vote their shares.

   Proxy Solicitation

   Compaq is soliciting proxies for the Compaq special meeting from Compaq
shareowners and HP is soliciting proxies for the HP special meeting from its
shareowners. Each company will share equally the cost of printing and filing
this joint proxy statement/prospectus and the registration statement on Form
S-4, of which it forms a part, that has been filed by HP with the Securities
and Exchange Commission.

   Other than the costs shared with HP, the cost of soliciting proxies from
Compaq shareowners will be paid by Compaq. In addition to solicitation by mail,
directors, officers and employees of Compaq may also solicit proxies from
shareowners by telephone, telecopy, telegram or in person. Compaq will also
make arrangements with brokerage houses and other custodians, nominees and
fiduciaries to send the proxy materials to beneficial owners. Upon request,
Compaq will reimburse those brokerage houses and custodians for their
reasonable expenses in so doing.

   Compaq has retained Georgeson Shareholder to assist it with the solicitation
of proxies and to verify certain records related to the solicitations. Compaq
will pay Georgeson Shareholder a fee of $45,000, plus their

                                      43



reasonable expenses, for these services. Compaq has agreed to indemnify
Georgeson Shareholder against certain liabilities resulting from claims
involving Georgeson Shareholder that directly relate to or arise out of
Georgeson Shareholder's engagement (except for those directly or principally
resulting from any gross negligence, bad faith or willful or intentional
misconduct by Georgeson Shareholder).

   Please do not send in any Compaq stock certificates with your proxy cards or
voting instruction cards. Computershare Trust Company of New York, the exchange
agent for the merger, will send transmittal forms with instructions for the
surrender of certificates representing shares of Compaq common stock to former
Compaq shareowners shortly after the merger is completed.

   Contact for Questions and Assistance in Voting

   Any Compaq shareowner who has a question about the merger or how to vote or
revoke a proxy should contact:

Other Matters


   Compaq is not aware of any other business to be acted upon at the Compaq
special meeting. If, however, other matters are properly brought before the
Compaq special meeting or any adjournment or postponement of the Compaq special
meeting, the persons named as proxy holders, Jeff Clarke and Thomas C. Siekman,
will have discretion to act on those matters, or to adjourn or postpone the
Compaq special meeting.

                                  THE MERGER

   The following is a description of the material aspects of the merger,
including the merger agreement. While we believe that the following description
covers the material terms of the merger, the description may not contain all of
the information that is important to you. We encourage you to read carefully
this entire joint proxy statement/prospectus, including the merger agreement
attached to this joint proxy statement/prospectus as Annex A, for a more
complete understanding of the merger.

Background of the Merger

   Each of HP and Compaq continually evaluates strategic opportunities and
business scenarios as a part of its ongoing evaluation of changes in the
marketplace and opportunities to strengthen its business. In 1999, due to an
increasingly competitive market environment, the HP board of directors and
members of HP management became particularly focused on developing strategies
to secure HP's future by strengthening HP's product and service offerings. In
particular, the HP board of directors sought strategic alternatives that would
enable HP to improve its enterprise computing and services businesses,
strengthen its sales force and improve its relationships with independent
software vendors.

   As part of this process, the HP board of directors and HP management
considered a range of strategic alternatives, including the following:

   .   a "go-it-alone" strategy that consisted of continuing its then-current
       business plan and making targeted acquisitions and divestitures designed
       to incrementally refine HP's product and service offerings;

   .   a "go-it-alone" strategy that consisted of continuing its then-current
       business plan coupled with shutting down, spinning-out, selling or
       otherwise divesting HP's PC business;

   .   a services-focused strategy that consisted of moving aggressively into
       information technology (IT) outsourcing and systems integration by
       developing alliances with, or acquiring, significant participants and
       assets in the IT services industry;

   .   an imaging and printing-focused strategy that consisted of strengthening
       its core printing and imaging business by intensifying its investment in
       higher-growth technologies and markets such as digital imaging, high-end
       printing and color printing, and by developing alliances with, or
       acquiring, other participants and assets in the imaging and printing
       industry;

   .   a spin-out of the imaging and printing business; and

   .   an end-to-end solutions strategy that consisted of developing its
       server, storage and services businesses by acquiring significant
       participants and assets in these industries, including Compaq.


   Throughout 1999 and 2000, the HP board of directors and HP management
continued to evaluate these strategic alternatives in light of evolving market
trends, industry dynamics and HP's relative position in the marketplace. By
mid-2000, the HP board of directors and HP management had determined, among
other things, to develop HP's IT services business further through various
methods, including organic growth fueled by increased internal investment in
the IT services business and possible acquisitions. In furtherance of this
portion of its strategy, HP entered into discussions with
PricewaterhouseCoopers LLP (PwC) regarding HP's potential acquisition of PwC's
consulting services business. In the fall 2000, HP decided to terminate
negotiations with PwC and continued to evaluate its strategic options in light
of market conditions, and in early 2001 HP retained McKinsey & Co. to assist in
this evaluation. During the past two fiscal years and through January 31, 2002,
HP has incurred consulting fees on matters unrelated to the merger with Compaq
to McKinsey & Co. of approximately $2.1 million. From McKinsey & Co.'s
engagement in connection with the merger and integration planning through
January 31, 2002, HP has incurred approximately $9.0 million in consulting fees
to McKinsey & Co. HP continues to incur consulting fees to McKinsey & Co. as
consulting services are performed at HP's request in connection with
integration planning and other consulting engagements. In addition, McKinsey &
Co. is reimbursed by HP for customary expenses in connection with its
consulting assignments.


                                      45



   Also in early 2001, in an effort to maximize opportunities for its UNIX(R)
business, HP began approaching other companies to determine whether they would
be interested in licensing HP's UNIX(R) operating system, HP-UX. As part of
these initiatives and following a series of previous discussions between
business unit representatives of both companies, Ms. Fiorina contacted Mr.
Capellas in June 2001 to discuss Compaq's interest in licensing HP-UX. After
several days of deliberation, Mr. Capellas contacted Ms. Fiorina to suggest
that the synergies between the two companies were broader than HP-UX and that
HP consider whether a broader strategic relationship might be a viable option.

   Based on the initial conversations between Ms. Fiorina and Mr. Capellas, on
June 22, 2001 Mr. Capellas and Shane V. Robison, Compaq's Senior Vice
President, Technology and Chief Technology Officer, met with Ms. Fiorina and
Duane E. Zitzner, HP's President, Computing Systems, to discuss the possibility
of Compaq licensing HP-UX. Although discussions regarding a licensing
arrangement between HP and Compaq continued beyond this meeting and are
ongoing, at this meeting, Ms. Fiorina and Messrs. Capellas, Zitzner and Robison
also discussed the potential for a broader relationship between HP and Compaq,
including a possible business combination.

   Following the June 22, 2001 meeting, HP initiated a general analysis of a
possible business combination with Compaq using publicly available information
to build upon the strategic evaluation it had performed with the assistance of
McKinsey & Co.

   On June 24, 2001, the HP board of directors convened a telephonic meeting.
All HP directors attended this meeting, other than Philip M. Condit, George A.
Keyworth II and Robert E. Knowling, Jr. In addition, Ann M. Livermore, HP's
President, HP Services, and Ann O. Baskins, HP's Vice President, General
Counsel and Secretary, and a representative of Wilson Sonsini Goodrich &
Rosati, Professional Corporation, outside counsel to HP, also attended this
meeting. During the meeting, after Ms. Livermore and Ms. Baskins had departed,
Ms. Fiorina apprised the HP board of directors of her discussions with Messrs.
Capellas and Robison and the preliminary analysis that HP had performed
regarding a possible business combination with Compaq. After discussion, the HP
board of directors authorized Ms. Fiorina to explore the business combination
further.

   On June 27, 2001, the Compaq board of directors convened a regular meeting.
All Compaq directors attended this meeting. Several members of Compaq
management (including Jeff Clarke, Compaq's Senior Vice President, Finance and
Administration and Chief Financial Officer, and Thomas C. Siekman, Compaq's
Senior Vice President and General Counsel) also attended this meeting. During
this meeting, Mr. Capellas informed the Compaq board of directors of his
conversations with Ms. Fiorina. Mr. Capellas and Mr. Robison presented the
preliminary analysis that Compaq had performed regarding Compaq business
strategies and the strategic rationale of a business combination with HP, and
the Compaq board of directors discussed the strategic rationale for the
business combination. The Compaq board of directors also discussed alternatives
to a business combination with HP and authorized management to continue to
explore a number of alternatives, including a business combination with HP.

   On June 27, 2001, Ms. Fiorina and Mr. Capellas had a telephonic meeting to
discuss further the business combination between HP and Compaq. During this
meeting, Ms. Fiorina and Mr. Capellas discussed their common beliefs in the
strategic rationale and benefits of a business combination and their respective
interests in further exploring a business combination between the two
companies. Ms. Fiorina confirmed that the HP board of directors was willing to
consider a business combination with Compaq and had authorized her to continue
discussions with Mr. Capellas regarding the terms of such a transaction. Mr.
Capellas also confirmed that the Compaq board of directors was interested in
exploring a business combination with HP and had authorized him to proceed with
discussions regarding a possible transaction with HP.

   On June 29, 2001, Ms. Fiorina, Robert P. Wayman, HP's Executive Vice
President, Finance and Administration, and Chief Financial Officer, Mr. Zitzner
and a representative from Wilson Sonsini Goodrich & Rosati, met with Mr.
Capellas, Mr. Clarke, Mr. Siekman and Mr. Robison to discuss various strategic,

                                      46



operational, legal and other regulatory issues associated with a possible
business combination between HP and Compaq.


   Following the June 29, 2001 meeting, HP and Compaq executed a
confidentiality agreement to facilitate further discussions and the related
exchange and use of confidential information. Compaq retained Accenture to
assist Compaq management in performing certain business due diligence of HP, an
assessment of strategic options available to Compaq, an analysis of the
rationale for the proposed business combination and a preliminary financial
analysis of the proposed business combination. During the past two fiscal years
and through January 31, 2002, Compaq has incurred consulting fees on matters
unrelated to the merger with HP to Accenture of approximately $46.9 million.
From Accenture's engagement in connection with the merger and integration
planning through January 31, 2002, Compaq has incurred approximately $2.5
million in consulting fees to Accenture. Compaq continues to incur consulting
fees to Accenture as consulting services are performed at Compaq's request in
connection with integration planning and other consulting engagements. In
addition, Accenture is reimbursed by Compaq for customary expenses in
connection with its consulting assignments. Shortly thereafter, HP, with the
assistance of McKinsey & Co., and Compaq, with the assistance of Accenture,
each initiated an extensive business due diligence investigation of the
business and operations of the other and a potential business combination. This
due diligence investigation included a review of the potential strategic
synergies of the business combination.


   On July 7, 2001, Ms. Fiorina and Messrs. Wayman and Zitzner of HP, together
with representatives from McKinsey & Co. and a representative from Wilson
Sonsini Goodrich & Rosati, met with Messrs. Capellas, Clarke, Siekman and
Robison of Compaq, together with representatives from Accenture, to further
discuss various strategic, operational, financial, legal and regulatory aspects
of the business combination. The parties also reviewed the results of their
respective preliminary analyses of the business combination, including the

negotiation of a definitive agreement for the business combination. As a result
of these agreements, Ms. Fiorina and Mr. Capellas agreed that HP and Compaq
should reinitiate discussions in connection with, and preparations for, the
business combination.

   During this period, Mr. Capellas communicated the status of discussions with
HP and consideration of other strategic alternatives to members of the Compaq

workforce. Representatives from Skadden, Arps, Slate, Meagher & Flom LLP joined
the committee, which then consisted of outside directors Ms. Craven and
Messrs. Babbio and Lay. In particular, the discussions focused on the
protections for Compaq employees under the proposed merger agreement, including
the provisions regarding ongoing benefits and severance programs, and on the
change in control protections in Compaq's existing compensation and benefit
programs. The committee discussed that the potential effect of uncertainties
created by the proposed merger could lead key employees, including executive
officers, to leave Compaq for other employment opportunities. To address this
issue, the committee approved certain revisions to existing executive severance
agreements and reviewed proposals for a retention program that would provide
incentives to key employees who remain with Compaq through the completion of
the merger and a critical transition period thereafter. Discussion of these
matters continued with the full Compaq board of directors when it convened
later that morning and throughout the negotiation process.

   On August 31, 2001, the HP board of directors convened a meeting to consider
further the business combination with Compaq. All HP directors attended this
meeting. In addition, Ms. Baskins, Susan D. Bowick, HP's Vice President and
Director, Corporate Human Resources, Mr. Charnas, Ms. Livermore and
representatives from Goldman Sachs, McKinsey & Co. and Wilson Sonsini Goodrich
& Rosati attended this meeting. During this meeting, Ms. Fiorina and other

                                      52




reasons for the business combination, reported on the status and current terms
and conditions of the business combination. Ms. Fiorina also provided the board
of directors with a report regarding her attendance at the Compaq board of
directors meeting, noting that the Compaq board of directors had expressed an
understanding of the potential synergies as well as the integration challenges
of the merger. Ms. Fiorina also updated the HP board of directors on the public
communications efforts planned for the transaction. Ms. Baskins then presented
a summary of HP's due diligence investigation of Compaq, outlining the various
topics that management and its advisors had addressed in their review and
noting the remaining due diligence to be completed prior to the signing of the
merger agreement. Representatives of McKinsey & Co. then reviewed HP's

combination based upon a range of exchange ratios. Following these
presentations, the HP board of directors discussed a number of issues that
remained unresolved in connection with the negotiation of the business
combination, including the final exchange ratio and certain management
retention issues, as well as the scope of the restrictions on Compaq's conduct
of business between the execution of the merger agreement and the completion of
the transaction, the rights and obligations of the parties upon receipt of
alternative acquisition proposals from third parties, the extent of efforts
required to complete the transaction and post-closing employee benefits for
Compaq employees. As a result of this discussion, the HP board of directors
directed members of the compensation committee of the board to further discuss
the unresolved management retention issues. The HP board of directors also
authorized HP's management to continue their negotiations with Compaq regarding
the terms and conditions of the business combination.


   Beginning at a meeting on August 31, 2001 and continuing until the execution
of the merger agreement on September 3, 2001, Messrs. Condit, Ginn and Hewlett,
the members of the compensation committee of the HP board of directors,
considered various management retention issues associated with the merger.
Messrs. Condit, Ginn and Hewlett discussed the fact that the success of the
combined company following the merger would be determined in part by how
effectively the combined company will be able to create a unified workforce
drawn from the existing talent of both HP and Compaq, and the risk that
uncertainty associated with the merger could lead some of HP's employees,
including executives, to accept other employment opportunities. To address
these issues, Messrs. Condit, Ginn and Hewlett, as the members of the
compensation committee acting on the authority of the full board, adopted a
retention program to assure the continued dedication of key employees and to
provide key employees with financial incentives to remain with the combined
company following the completion of the merger.

   On September 2 and September 3, 2001, members of the management of HP and
Compaq and their respective financial and legal advisors met at the offices of
Skadden, Arps, Slate, Meagher & Flom LLP in New York City to negotiate the
final terms and conditions of the merger agreement and to prepare for the
announcement of the transaction. During these meetings, Mr. Wayman and Mr.
Clarke, and the companies' respective financial advisors, had several
conversations regarding the appropriate exchange ratio for the business
combination in light of the agreed upon approach to determine the exchange
ratio that had been previously agreed upon by Ms. Fiorina and Mr. Capellas, as
well as various management retention issues. Mr. Wayman and Mr. Clarke
ultimately agreed upon the exchange ratio of 0.6325 of a share of HP common
stock for each share of Compaq common stock, subject to approval of the boards
of directors of HP and Compaq and final agreement on the terms and conditions
of the merger agreement. Ms. Fiorina and Mr. Capellas agreed on this exchange
ratio as well, subject to the board approvals.

   On September 3, 2001, the HP board of directors convened a meeting to
consider the business combination and the terms and conditions of the merger
agreement that had been negotiated by the management teams of HP

                                      53



and Compaq. All HP directors attended this meeting. In addition, Ms. Baskins,
Mr. Charnas and representatives from Goldman Sachs, McKinsey & Co. and Wilson
Sonsini Goodrich & Rosati attended this meeting. At this meeting, Ms. Fiorina
described her meetings with Mr. Capellas and the agreements she had reached
with him regarding the exchange ratio for the business combination, management
retention, regulatory and various other issues associated with the business
combination. Following Ms. Fiorina's presentation, representatives from Goldman
Sachs again reviewed HP's assessment of the strategic rationale for the
business combination and presented a financial analysis with respect to the
business combination based upon the exchange ratio in the merger agreement that
had been negotiated by Ms. Fiorina and Mr. Capellas. Based upon the foregoing,
Goldman Sachs then delivered its opinion that, as of the date of the merger
agreement and subject to the assumptions, considerations and limitations set
forth in its opinion, the exchange ratio provided for in the merger agreement
is fair, from a financial point of view, to HP. The HP board of directors then
discussed the reasons for the merger, including the financial analysis and the
risks associated with the merger. After deliberating on the foregoing, the HP
board of directors unanimously determined that the merger is advisable, and is
fair to and in the best interests of HP and its shareowners, approved the
merger agreement, directed that the issuance of shares of HP common stock in
connection with the merger be submitted for consideration by HP shareowners at
a special meeting of HP shareowners, and resolved to recommend that HP
shareowners vote "for" the proposal to approve the issuance of shares of HP
common stock in connection with the merger.

   Also on September 3, 2001, the Compaq board of directors convened a meeting
to consider the business combination and the terms and conditions of the merger
agreement that had been negotiated by the management teams of HP and Compaq.

Mr. Clarke and Mr. Siekman) and representatives from Salomon Smith Barney and
Skadden, Arps, Slate, Meagher & Flom LLP also attended this meeting. At this
meeting, Mr. Capellas reported on the series of negotiations and meetings with
HP and its management and advisors over the last few days and the agreements
that had been reached regarding the exchange ratio, management retention, and
regulatory and various other issues. Representatives from Salomon Smith Barney
again presented a financial analysis with respect to the business combination
and delivered its opinion that, as of the date of its opinion and based upon
and subject to the assumptions, considerations and limitations set forth in its
opinion, the exchange ratio provided for in the merger agreement is fair, from
a financial point of view, to the holders of Compaq common stock. After
deliberation, the Compaq board of directors unanimously determined that the
merger is fair to, and in the best interests of, Compaq and its shareowners and
declared the merger to be advisable, approved the merger agreement, resolved to
recommend that the shareowners of Compaq approve and adopt the merger agreement
and approve the merger, and directed that such matter be submitted to Compaq's
shareowners at a meeting of Compaq shareowners.

   Following the meetings of the board of directors of each of HP and Compaq,
HP and Compaq executed the merger agreement as of September 4, 2001.

voted upon by HP shareowners.

   On December 5, 2001, Walter B. Hewlett filed solicitation material with the
Securities and Exchange Commission, which contained further financial analysis
of the merger.

   On December 7, 2001, the David and Lucile Packard Foundation announced its
preliminary determination to vote its shares of HP common stock against the
proposal to approve the issuance of shares of HP common stock in connection
with the merger.

   On December 12, 2001, Walter B. Hewlett sent a letter to the board of
directors of each of HP and Compaq urging the directors of both companies to
reconsider their support for the merger and unwind the merger.

   On December 13, 2001, Mr. Hackborn announced that he had resigned from the
board of directors of The William and Flora Hewlett Foundation due to his
belief that a conflict of interest had arisen as a result of the opposition to
the merger by Walter B. Hewlett and The William and Flora Hewlett Foundation.


   On December 19, 2001, HP filed solicitation material with the Securities and
Exchange Commission further discussing HP's position on the merger.


   On December 27, 2001, Walter B. Hewlett, Mr. van Bronkhorst and The William
R. Hewlett Revocable Trust filed a preliminary proxy statement with the
Securities and Exchange Commission in connection with their intended
solicitation of proxies from HP shareowners against the proposal to approve the

Reasons for the Merger

   Overview

   The boards of directors and management teams of both HP and Compaq believe
that the proposed merger represents the best strategic alternative for
delivering increased value to our respective shareowners addressing a number of
challenges and opportunities facing our companies. Several of these
opportunities and challenges are described below.


   HP and Compaq share the conviction that advances in technology, increased
competition and changing customer requirements are rapidly transforming the
structure and economics of the information technology (IT) industry in ways
that demand quick and decisive action to remain competitive. In the area of
enterprise computing and IT services--areas we consider to be the primary
engines for new value creation--customers increasingly are looking to purchase
integrated solutions, not individual products and technologies, from a smaller
number of global end-to-end solutions providers. These customers also are
seeking to take advantage of the economics and flexibility of standards-based
platforms and architectures. Accordingly, we must expand the scope of our
leadership across the enterprise.


   In the personal computer (PC) segment of the industry, which is maturing and
consolidating, customers are looking for low cost products with greater
features and functionality, as well as purchasing flexibility. As a result of
these customer demands and intense competition among PC vendors, success in the
PC industry requires increasingly lower cost structures, flexible distribution
capabilities and continuous product innovation. HP has already undertaken
independent actions, such as the recently announced outsourcing of its PC
manufacturing operations in France, to improve the cost structure of this
business, but HP recognizes that additional cost saving measures will be
required.

   In the services segment, both companies operate profitable, growing services
businesses, but neither company alone has a services business of the size that
places it among the top few global IT services businesses on a revenue basis.
Accordingly, both HP and Compaq believe that the expansion of their services
businesses is an important source of growth and profitability for their
companies.

   In addition, HP has identified the expansion of its imaging and printing
business into new areas of growth as essential to maintaining leadership in
that segment. HP's pending acquisition of Indigo N.V. is an example of

                                      56



these efforts. HP believes that the strengthening of its professional services
capabilities and its PC business, the expansion of its reach into enterprise
accounts and improvements in the profitability of those businesses will benefit
the long-term success of its imaging and printing business in new and emerging
markets.


   The boards of directors and management teams of both HP and Compaq
rigorously analyzed numerous alternative strategies to position their companies
to take advantage of the opportunities and address the challenges presented by
these trends. See the section entitled "Background of the Merger" beginning on
page 45 of this joint proxy statement/prospectus. After reviewing and debating
these strategic alternatives and the opportunities presented by the merger, the
boards of directors and management teams of both HP and Compaq determined to
pursue the merger in lieu of the other alternatives that were being considered
independently because we believe that the merger provides a unique opportunity
to position ourselves broadly to address the strategic challenges of our
industries. In addition, combining our companies offers the most comprehensive
opportunity among our alternatives for improving our cost structures and
improving the long-term profitability of our enterprise systems and PC
businesses in a timely and efficient manner.



   In fact, we believe that the merger is a unique opportunity to create a
combined company with a stronger, more efficient operating model than either
company could achieve on its own. For example, the merger will enable us to
improve our combined earnings by generating significant cost synergies for the
combined company. We expect to generate annual cost savings of at least $2.5
billion by the middle of the combined company's 2004 fiscal year, which in and
of itself, as noted below, translates into a present value of cost savings of
approximately $5-$9 per share of the combined company (based on the assumptions
described in the section entitled "Financial Benefits of the Merger" beginning
on page 59 of this joint proxy statement/prospectus). In addition, even in an
environment in which prices will remain under pressure, we believe that the
combined company will be able to generate operating margins of 8%-10% by the
combined company's 2003 fiscal year after realizing anticipated cost savings.


   At the same time that we believe the proposed merger provides significant
benefits, we believe that failure to take quick and decisive action to address
comprehensively the business opportunities and challenges facing our respective
businesses will weaken our respective long-term competitive positions and
result in the deterioration of our respective businesses. Similarly, we believe
that maintaining the status quo or moving too slowly to address these items
ultimately will erode the value of both companies to our respective shareowners.

   Strategic Benefits of the Merger


   We believe that the merger presents a unique opportunity to enhance our
combined competitive position in key industries, while strengthening our sales
force and our relationships with important constituencies, all in a single
transaction. As global enterprises look to maintain stronger partnerships with
a smaller number of vendors, it will be crucial not only to have offerings
across a broad spectrum of products, but also to have market-leading products
and solutions across that spectrum. The merger will greatly expand and
strengthen our product and service offerings, make us a compelling partner, and
provide a more robust platform for innovation, all of which will combine to
accelerate our leadership position as an end-to-end solutions provider.


   Servers: Complementary Leadership in Key Markets

   HP and Compaq offer complementary solutions that, taken together, will give
the combined company industry-leading product offerings spanning the server
category. For instance, Compaq's Himalaya offering is the segment leader in
fault-tolerant servers with enhanced failure protection for critical business
operations where system outages are very disruptive (such as stock exchanges).
HP does not currently offer fault-tolerant systems. Compaq is also the segment
leader in industry standard servers--the fastest growing area in the server
industry--that operate on third-party operating systems like Microsoft Windows
NT and Linux. Combining these offerings with HP's strength in mid- to high-end
UNIX(R) servers, which we believe will be further enhanced by Compaq's
technology, fills out the combined company's server leadership. Combining the
companies' respective investments in Linux will also enhance the combined
company's innovation in this area.

                                      57



   Storage: Complementary Fit Creates Leadership Across Categories, Including
   Highest Growth Areas

   Compaq is the leading provider of storage systems in the world, measured on
a revenue basis. Combining this leadership position with HP's strength in
high-end storage will create an even stronger industry leader in the enterprise
storage area and especially in the fastest growing portion of storage--storage
area networks--where Compaq's StorageWorks products will enable our customers
to manage complex storage environments more efficiently. HP's virtualization
software, which it recently acquired through the acquisition of StorageApps
Inc. will enable the combined company to market its broad array of storage
products to customers whose current storage networks are not interoperable with
either HP or Compaq technology.

   IT Services: Strengthened Business Provides Critical Mass in Key Growth
   Market

   The merger also will significantly strengthen our combined services business:

   .   The combined company will have available 65,000 IT architects operating
       in more than 160 countries around the world, who we believe will provide
       the critical mass and scale to accelerate our growth in this key growth
       market. Customers demand global presence from their IT service
       providers, and the merger will significantly improve our combined
       ability to offer IT services around the world.

   .   The merger will expand our combined support business, which is an
       important driver of customer loyalty and provides a larger customer base
       to whom the combined company can sell additional products and services.
       We also believe that our combined support business also will deliver a
       larger stream of predictable, regular revenues with double-digit net
       profits.

   .   With our combined capabilities in IT outsourcing and utility-based
       computing, we will have an opportunity to lead in managed services, a
       fast-growing segment of the services market.

   .   By combining our strengthened offering in the server market with our
       increased services capabilities, the combined company will be well
       positioned as a leading provider of mission-critical services.


   .   The combined company's expertise in UNIX(R) environments, NT
       environments, Linux, storage, the desktop, printing and wireless
       devices, along with expertise in multi-vendor technologies, will make
       the combined company a leader in multi-vendor support.


   Personal Systems: Improves Economics and Drives Innovation

   We each recognize the need to improve the overall economics of our
respective PC businesses to create a sustainable and viable competitor. The
combined company will have greater economies of scale that we believe will
lower the cost structure of our combined PC business and have a positive impact
on margins. In fact, we believe that the merger will enable us to achieve
positive operating margins of 3% in our personal systems business (compared to
an operating margin for HP's personal systems business of (4.2%) in fiscal year
2001) by the middle of the combined company's 2003 fiscal year. Further, the
merger will combine HP's strength in the consumer PC business and Compaq's
strength in the commercial PC business to create a more balanced industry
leader.

   In addition, Compaq has made significant progress developing its direct
distribution capabilities in its PC business, which the combined company will
be able to leverage to create a more flexible distribution model. For instance,
Compaq directly distributed 70% of its North American volume last quarter
(versus 15% for HP) and managed 62 inventory turns last quarter (versus 25 for
HP). With this progress and the accelerating momentum Compaq has demonstrated
as a direct distributor, we believe the merger will substantially enhance HP's
distribution model.

   We also intend to create sustainable value in our PC and other personal
systems businesses by innovating across emerging categories and delivering a
new generation of connected access and embedded devices. In doing so, we will
draw upon our respective innovations, including such leading devices as the
Compaq iPaq and the HP

                                      58



Jornada Pocket PC, as well as HP's new print services. In fact, we believe that
the integration of innovative personal systems and digital imaging will create
significant new opportunities for growth.

   Imaging and Printing: Enhances Market Leader, Expanding R&D and New
   Initiatives

   The merger also will provide important benefits to HP's imaging and printing
systems (IPS) business. By improving profitability in our other business
segments, the merger will enable us to increase our investment in core IPS
research and development and new IPS initiatives such as digital imaging and
digital publishing. HP believes that this investment will be crucial to
maintaining its leading position in the IPS business, HP's primary cash
generator. Further, we believe that the future of our IPS business will extend
beyond pure printing to providing solutions that store, manage and deliver rich
content. We believe that, as markets such as digital imaging and digital
publishing develop, our IPS business will benefit from the combined company's
expertise in creating comprehensive enterprise solutions that are capable of
storing, managing and delivering rich content. In addition, the merger will
enable HP to extend the reach of its IPS business into new enterprise accounts
that Compaq brings to the combined company, and take advantage of Compaq's
direct distribution capability to enhance the distribution flexibility of the
combined company's IPS business.

   Sales Force: Expands Coverage

   HP and Compaq recognize the importance of improving our overall account
coverage to compete effectively for important customer engagements around the
world. The combined company will have a sales force of 15,000 by combining HP's
current sales force of 7,000 with Compaq's current sales force of 8,000,
thereby greatly enhancing our ability to reach our customers in all industries
in which the combined company will operate.

   Important Constituencies: Improves Positioning

   We also believe that the merger will enable the combined company to deliver
greater value to its shareowners by better serving our respective customers, as
well as our respective partners and employees.

   .   Customers.  The combined company will have a broader, deeper portfolio
       of compelling products, services and technologies than either HP or
       Compaq alone, together with the enhanced capability to integrate those
       products and services into solutions tailored to meet the needs of our
       diverse customer base.

   .   Partners.  The combined company will be a more compelling partner
       because its commitment to open standards, together with the combined
       company's large customer base, will attract developers who are choosing
       their initial development platforms. We consider this key to our
       strategy, as the delivery of integrated end-to-end solutions requires
       that providers of software and microprocessors, among others, develop
       their products to be compatible with our products, and that independent
       systems integrators develop alliances with our solutions organizations.

   .   Employees.  The combined company will be well positioned to attract and
       retain the best employees because of its stronger, healthier businesses
       and increased depth of leadership--attributes that create greater
       long-term opportunity for growth and career advancement.

   Financial Benefits of the Merger

   In addition to the strategic benefits of the merger discussed above, the
merger will enable the combined company to generate substantial cost savings
and improve the profitability of our combined enterprise, personal systems and
services businesses. In addition to generating shareowner value through
improved earnings, these cost savings offer strategic benefits by reducing our
cost structure in competitive businesses such as PCs.

                                      59



   Synergies

   We believe that the merger will enable the combined company to generate
annual cost savings of $2.5 billion by the middle of the combined company's
2004 fiscal year. We anticipate that these cost savings will be realized by the
combined company in the following categories:



                                                                Anticipated
    Category                                                    Cost Savings
    --------                                                    ------------
                                                             
    Administrative/IT costs.................................... $625 million
    Cost of goods sold benefits................................ $600 million
    Sales management benefits.................................. $475 million
    Research and development efficiencies...................... $425 million
    Indirect purchasing benefits............................... $250 million
    Marketing efficiencies..................................... $125 million


   We expect that the combined company will realize the anticipated cost
synergies in each of these categories as follows:

   .   in administrative and IT costs by eliminating redundant IT investment
       following the completion of the merger and by eliminating redundant
       positions across corporate administration, finance, human resources and
       IT personnel;

   .   in costs of goods sold by reducing materials costs, consolidating
       manufacturing operations and discontinuing duplicative infrastructure
       investments;

   .   in sales management by eliminating redundant positions;

   .   in research and development by eliminating duplicative research and
       development efforts, principally in the combined company's PC and server
       businesses;

   .   in indirect purchasing spending by reducing the combined company's
       indirect purchasing base; and

   .   in marketing by eliminating redundant product marketing personnel and by
       eliminating redundant marketing and communications programs.

   These cost savings have a net present value of approximately $5-$9 per share
of the combined company calculated by applying a range of price/earnings
multiples to the estimated earnings per share impact of these cost savings in
calendar 2004 and discounting those amounts to the present. This analysis is
based on the following assumptions:

   .   $2.5 billion of pretax cost savings in calendar year 2004;


   .   a range of price/earnings multiples of 15x-25x, which is supported by
       the average one-year forward price/earnings multiple for HP in the last
       year (20.8x) and the last three years (22.2x);


   .   a discount rate of 15%, which is based upon the weighted average cost of
       equity of the combined company on a pro forma basis;

   .   an assumed effective tax rate of 26% for the combined company, which is
       based upon the weighted average of the effective tax rates of each of HP
       and Compaq;


   .   marginal pretax profit decline of approximately $500 million in calendar
       year 2004 resulting from estimated overall revenue loss for the combined
       company resulting from the merger in calendar year 2004 of approximately
       $4.1 billion (representing 4.5% of overall estimated revenue for
       calendar year 2004 of $92.8 billion or 4.9% of estimated revenue for
       fiscal year 2003), which is based upon potential revenue loss in
       businesses of the combined company as follows: 18% in home PCs; 11% in
       UNIX(R) servers; 8% in business PCs; 7% in appliances; 6% in NT servers;
       and 5% in storage. We have assumed that our combined imaging and
       printing business will not experience material revenue losses


                                      60



       as a result of the merger because Compaq does not have an imaging and
       printing business. In addition, we have assumed that our combined
       services business will not experience material net revenue losses as a
       result of the merger;

   .   a weighted average contribution margin of 12%, which represents the
       marginal pretax profit decline resulting from revenue loss. We have
       assumed a weighted average contribution margin of 12%, reflecting an
       assumed contribution margin of 11% for the combined company's Personal
       Systems business (which is expected to account for 66% of 2004 revenue
       loss) and 14% for the combined company's Enterprise business (which is
       expected to account for 34% of 2004 revenue loss); and

   .   our estimate of the net present value of the cost savings resulting from
       the merger excludes both the cost savings expected to result from the
       merger in calendar years 2002 and 2003 and the expected non-recurring
       cash costs of achieving those cost savings (e.g., costs of integration)
       during those calendar years, as well as the pretax profit decline
       resulting from estimated revenue loss in calendar years 2002 and 2003.
       Our estimate of the net present value of the cost savings resulting from
       the merger does not account for possible revenue increases resulting
       from the merger.

   Based upon the revenue loss assumption described above and a weighted
average contribution margin of 12%, the combined company would have to lose
approximately $20.6 billion of overall revenue in calendar year 2004 as a
result of the merger (i.e., more than five times the amount of our assumed
revenue loss resulting from the merger) in order to completely offset our
anticipated annual cost savings of $2.5 billion resulting from the merger.


   Our estimate of the $2.5 billion of cost savings resulting from the merger
was prepared by HP management with the assistance of McKinsey & Co. The
assumptions upon which the present value of our estimate of the cost savings
resulting from the merger were developed by HP management. In addition, Goldman
Sachs relied upon our estimate of the annual cost savings resulting from the
merger in connection with rendering its written opinion to the HP board of
directors that the exchange ratio provided for in the merger agreement is fair,
from a financial point of view, to HP. We note that Goldman Sachs performed
different types of analyses utilizing our estimates of annual cost savings;
these different analyses resulted in different ranges of per share values of
the estimated annual cost savings. The analyses of Goldman Sachs, together with
methodologies used, are described in the section entitled "Opinion of HP
Financial Advisor" on page 65 of this joint proxy statement/prospectus.


   There can be no assurance that the net present value of our anticipated cost
savings resulting from the merger will be reflected in the trading price of HP
common stock following the completion of the merger.

   Operating Margins

   In addition, even in an environment in which prices will remain under
pressure, we believe that the combined company will be able to generate an
overall operating margin of 8%-10% in the combined company's 2003 fiscal year,
after realizing anticipated cost savings (compared to an HP operating margin of
approximately 3% in fiscal year 2001). Specifically, we believe that the
combined company will have the following business segment operating margins in
the combined company's 2003 fiscal year:

   .   Enterprise Systems business operating margins of 9.2% (compared to an
       operating margin for HP's comparable businesses of -3.2% in fiscal year
       2001).

   .   Personal Systems business operating margins of 3.0% (compared to an
       operating margin for HP's comparable businesses of -4.2% in fiscal year
       2001).

   .   Services business operating margin of 13.7% (compared to an operating
       margin for HP's comparable businesses of 4.5% in fiscal year 2001).

                                      61



Consideration of the Merger by the HP Board of Directors

   Recommendation of the HP Board of Directors

   At a meeting held on September 3, 2001, the HP board of directors
unanimously:

    .  determined that the merger is advisable, and is fair to and in the best
       interests of HP and its shareowners;

    .  approved the merger agreement;

    .  directed that the issuance of shares of HP common stock in connection
       with the merger be submitted for consideration by HP shareowners at an
       HP special meeting; and

    .  resolved to recommend that the HP shareowners vote "for" the proposal to
       approve the issuance of shares of HP common stock in connection with the
       merger.


   Among other things considered by the HP board of directors in making this
recommendation, the HP board of directors requested and considered the written
opinion of Goldman Sachs, described below in the section entitled "Opinion of
HP Financial Advisor" beginning on page 65, that as of September 3, 2001 and
subject to the assumptions, considerations and limitations set forth in its
opinion, the exchange ratio provided for in the merger agreement is fair, from
a financial point of view, to HP. The Goldman Sachs opinion addresses the
fairness of the merger to HP, and the HP board of directors has determined that
the merger is advisable, and is fair to and in the best interests of HP and its
shareowners, based upon its consideration of the Goldman Sachs opinion and
numerous other factors described below.


   In reaching its decision to approve the merger agreement, the HP board of
directors consulted with HP's management, HP's legal counsel regarding the
legal terms of the merger, HP's business consultants regarding the strategic
aspects of the merger and alternatives to the merger, and HP's financial
advisors regarding the financial aspects of the merger and the fairness, from a
financial point of view, of the exchange ratio to HP. The factors that the HP
board of directors considered in reaching its determination include, but were
not limited to, the following:


    .  the reasons for the merger described in the section entitled "Reasons
       for the Merger" beginning on page 56 of this joint proxy
       statement/prospectus;


    .  historical information concerning HP's and Compaq's respective
       businesses, prospects, financial performance and condition, operations,
       technology, management and competitive position, including public

       and limitations set forth in its opinion, its work described in the
       section entitled "Opinion of HP Financial Advisor" beginning on page 65
       of this joint proxy statement/prospectus, its experience as investment
       bankers and other factors it deemed relevant, the exchange ratio
       provided for in the merger agreement is fair, from a financial point of
       view, to HP. A copy of Goldman Sachs' written opinion is attached to
       this joint proxy statement/prospectus as Annex B;


    .  the impact of the merger and its announcement on HP's customers,
       suppliers and employees;

    .  the fact that HP shareowners will have the opportunity to vote upon the
       proposal to approve the issuance of shares of HP common stock in
       connection with the merger;


    .  the interests that certain executive officers and directors of HP may
       have with respect to the merger in addition to their interests as
       shareowners of HP generally, as described in more detail in the section
       entitled "Interests of HP Directors and Executive Officers in the
       Merger" beginning on page 83 of this joint proxy statement/prospectus;
       and


    .  reports from management, legal and financial advisors as to the results
       of the due diligence investigation of Compaq.

   In addition, the HP board of directors also identified and considered a
variety of potentially negative factors in its deliberations concerning the
merger, including, but not limited to:

    .  the risk that the potential benefits sought in the merger might not be
       fully or immediately realized, including:

       -  the belief of HP management that it will not begin to realize the
          benefits of the anticipated synergies until mid-2002 and will not
          fully realize these synergies until HP's fiscal year 2004;

       -  possible difficulties in integrating two organizations of the size
          and complexity of HP and Compaq, which could delay or negate some of
          the expected benefits of the merger;

       -  the risk that, notwithstanding the long-term benefits of the merger,
          HP's financial results and stock price might decline in the short
          term;


       -  possible effects on HP's long-term stock price and financial results
          if the benefits of the merger are not obtained on a timely basis or
          at all;


    .  the possibility that the merger might not be completed, or that
       completion might be unduly delayed, and the effect of public
       announcement of the merger on HP's sales and operating results, and HP's
       ability to attract and retain key management, marketing and technical
       personnel;

    .  the substantial charges to be incurred in connection with the merger,
       including costs of integrating HP and Compaq and transaction expenses
       arising from the merger;

    .  the risk that despite the efforts of the combined company, key technical
       and management personnel might not remain employed by the combined
       company;

    .  the terms of the merger agreement regarding HP's right to consider and
       negotiate acquisition proposals in certain circumstances, as well as the
       possible effects of the provisions regarding the termination fees; and


    .  various other risks associated with the merger and the businesses of HP
       and the combined company described in the section entitled "Risk
       Factors" beginning on page 23 of this joint proxy statement/prospectus.


   The HP board of directors concluded, however, that these negative factors
could be managed or mitigated by HP or by the combined company or were unlikely
to have a material impact on the merger or the combined company, and that,
overall, the potentially negative factors associated with the merger were
outweighed by the potential benefits of the merger. For example, the HP board
of directors believed that:

    .  the merger could be completed on the proposed terms;

                                      63



    .  HP could implement appropriate retention programs for its personnel and
       minimize negative effects on its customer relationships;

    .  should a business not perform to expectations following the merger, a
       disposition could be evaluated in the future;

    .  costs relating to the merger would not exceed the proposed benefits of
       the merger;

    .  the long-term strategic benefits would outweigh any short-term negative
       impact on the company's financial results and stock price; and


    .  the HP board of directors' and management team's experience with prior
       acquisitions and other complex transactions, combined with the detailed
       review of integration challenges and requirements presented to the HP
       board, created confidence that the integration process would be
       successfully managed.


   The above discussion of the material factors considered by the HP board of
directors is not intended to be exhaustive, but does set forth the principal
factors considered by the HP board of directors. The HP board of directors
collectively reached the unanimous conclusion to approve the merger agreement
and the merger in light of the various factors described above and other
factors that each member of the HP board of directors felt were appropriate. In
view of the wide variety of factors considered by the HP board of directors in
connection with its evaluation of the merger and the complexity of these
matters, the HP board of directors did not consider it practical, and did not
attempt, to quantify, rank or otherwise assign relative weights to the specific
factors it considered in reaching its decision. Rather, the HP board of
directors made its recommendation based on the totality of information
presented to and the investigation conducted by it. In considering the factors
discussed above, individual directors may have given different weights to
different factors.


   Since the announcement of the merger, each of HP and Compaq has released
updated financial results. See the section entitled "Summary Selected
Historical Consolidated Financial Data of HP" beginning on page 15 of this
joint proxy statement/prospectus, and "Summary Selected Historical Consolidated
Financial Data of Compaq" beginning on page 17 of this joint proxy
statement/prospectus. In addition, since the announcement of the merger, Wall
Street estimates of the future financial performance of HP and Compaq have been
available that differ from the estimates considered by the HP board of
directors at the time it approved the merger. Specifically, First Call
consensus estimates used in HP's solicitation materials filed with the
Securities and Exchange Commission on December 19, 2001 for HP earnings per
share for fiscal year 2003 of $1.28 are 8.5% higher than the estimates for the
same period extrapolated from available First Call consensus estimates
considered by the HP board of directors at the time it approved the merger. In
the case of Compaq, First Call consensus estimates available at December 19,
2001 for Compaq earnings per share for fiscal year 2003 of $0.42 are 33% lower
than the estimates for the same period extrapolated from available First Call
consensus estimates considered by the HP board of directors at the time it
approved the merger.


   HP believes that, even after taking these developments into account, the
merger will result in a substantial increase of approximately 13% to estimated
HP fiscal 2003 earnings per share, based on the updated Wall Street estimates
of the future financial performance of HP and Compaq described above. This
estimate is based upon the 26% tax rate, 4.9% revenue loss and 12% weighted
average contribution margin assumptions described above, and does not take into
account any impact of non-cash charges associated with goodwill and intangible
asset amortization.

   The HP board of directors believes that the merger is advisable, and is fair
to and in the best interests of HP and its shareowners.

    Opinion of HP Financial Advisor

   On September 3, 2001, Goldman Sachs delivered its written opinion to the HP
board of directors that, as of that date and subject to the assumptions,
considerations and limitations set forth in its opinion, the exchange ratio in
the merger of 0.6325 of a share of HP common stock for each share of Compaq
common stock is fair, from a financial point of view, to HP. The full text of
the opinion of Goldman Sachs, which sets forth assumptions made, matters
considered and limitations on the review undertaken by Goldman Sachs in
connection with rendering the opinion, is attached to this joint proxy
statement/prospectus as Annex B.

   Goldman Sachs provided the opinion described above for the information and
assistance of the HP board of directors in connection with its consideration of
the merger. The terms of the merger agreement and the exchange ratio in the
merger, however, were determined through negotiations between HP and Compaq,
and were approved by the HP board of directors.

   HP shareowners are urged to read the opinion provided by Goldman Sachs to
the HP board of directors carefully and in its entirety. In addition, HP
shareowners should carefully consider the following description of the analysis
performed by Goldman Sachs in connection with rendering its opinion when HP
shareowners determine whether to approve the issuance of shares of HP common
stock in connection with the merger. The opinion of Goldman Sachs described
above is not a recommendation as to how any HP shareowner should vote with
respect to the proposal to approve the issuance of shares of HP common stock in
connection with the merger.

   In connection with rendering the opinion described above and performing its
related financial analyses, Goldman Sachs reviewed, among other things:

    .  the merger agreement;

    .  the Annual Reports to Shareowners and Annual Reports on Form 10-K of HP
       for the five fiscal years ended October 31, 2000;

    .  the Annual Reports to Shareholders and Annual Reports on Form 10-K of
       Compaq for the five years ended December 31, 2000;

    .  interim reports to shareowners and Quarterly Reports on Form 10-Q of HP
       and Compaq;

    .  other communications from HP and Compaq to their respective shareowners;
       and

    .  internal financial analyses and forecasts for HP and Compaq prepared by
       their respective managements, including certain cost savings and
       operating synergies projected by the management of HP to result from the
       merger.

   Goldman Sachs also held discussions with members of the senior managements
of HP and Compaq regarding their assessment of the strategic rationale for, and
the potential benefits of, the merger and the past and current business
operations, financial condition and future prospects of their respective
companies. In addition, Goldman Sachs reviewed the reported price and trading
activity of shares of HP common stock and Compaq common stock, compared certain
financial and stock market information for HP and Compaq with similar
information for certain other companies the securities of which are publicly
traded, reviewed the financial terms of certain recent business combinations in
the computer hardware industry specifically and in other industries generally
and performed such other studies and analyses as it considered appropriate.

   Goldman Sachs relied upon the accuracy and completeness of all of the
financial, accounting and other information discussed with or reviewed by it
and assumed such accuracy and completeness for purposes of rendering the
opinion described above. In that regard, with the consent of the HP board of
directors, Goldman Sachs assumed that the internal financial forecasts prepared
by the managements of HP and Compaq, including certain cost savings and
operating synergies projected by the management of HP to result from the
merger, were reasonably

                                      65



prepared on a basis reflecting the then best currently available estimates and
judgments of HP and Compaq, and will be realized in the amounts and time
periods provided to Goldman Sachs. In addition, Goldman Sachs did not make an
independent evaluation or appraisal of the assets and liabilities of HP or
Compaq or any of their respective subsidiaries, and no evaluations or
appraisals of the assets or liabilities of HP or Compaq or any of their
respective subsidiaries were provided to Goldman Sachs. Goldman Sachs also
assumed that all material governmental, regulatory or other consents and
approvals that are necessary for the completion of the merger will be obtained
without any meaningful adverse effect on HP or Compaq or on the contemplated
benefits of the merger.

    Financial Analyses

   The following is a summary of the material financial analyses used by
Goldman Sachs in connection with rendering the opinion described above. The
following summary, however, does not purport to be a complete description of
the analyses performed by Goldman Sachs. To the extent that the following
quantitative information is based on market data or internal financial
forecasts prepared by the managements of HP and Compaq, such quantitative
information is based on such market data and financial forecasts as they
existed at or about August 31, 2001 and is not necessarily indicative of
current conditions. Some of the summaries of the financial analyses below
include information presented in tabular format. The tables alone are not a
complete description of Goldman Sachs' financial analyses and should be read
together with the full text of each summary.

   Contribution Analysis.  Goldman Sachs performed a contribution analysis in
which Goldman Sachs analyzed and compared:

    .  the relative contributions to be made by each of HP and Compaq on a
       percentage basis to the revenue, operating income, profit before taxes
       and net income of the combined company on a pro forma basis assuming the
       completion of the merger; and

    .  the relative ownership of the combined company implied from their
       relative contributions, on a percentage basis, by the shareowners of HP
       and the shareowners of Compaq on a pro forma basis assuming the
       completion of the merger.

   Goldman Sachs determined the relative contributions to be made by each of HP
and Compaq to the combined company based upon publicly available information
regarding HP and Compaq, as well as certain analysts' reports and estimates and
information provided by the management of HP and Compaq with respect to the
financial performance of each company. The contribution analyses that Goldman
Sachs performed, however, did not take into account any revenue gains or losses
or expense synergies expected by HP management to be achieved by the combined
company following the completion of the merger. The results of Goldman Sachs'
contribution analysis of the relative percentage contributions to be made by
each of HP and Compaq to the combined company are presented in the table below
under the caption "Percentage Contribution to the Combined Company."

   In connection with its contribution analysis, Goldman Sachs also used the
relative percentage contributions of HP and Compaq to the revenue, operating
income, profit before taxes and net income of the combined company to derive a
range of implied exchange ratios for the merger of between 0.524 and 1.000 in
comparison to the actual exchange ratio for the merger of 0.6325. The results
of this analysis are also presented in the table below under the caption
"Implied Exchange Ratio."

                                      66




   For comparative purposes, Goldman Sachs then calculated the relative implied
ownership of the combined company using the exchange ratio in the merger of
0.6325 of a share of HP common stock for each share of Compaq common stock. The
results of Goldman Sachs' contribution analysis of the relative implied
ownership of the combined company are presented in the table below under the
caption "Percentage Contribution to the Combined Company."

   Historical Exchange Ratio Analysis.  Goldman Sachs also performed a
historical exchange ratio analysis in which Goldman Sachs compared:

    .  a series of implied exchange ratios for the merger derived from
       historical trading prices of HP common stock and Compaq common stock
       over certain specified periods of time beginning August 31, 2000 and
       ending August 31, 2001, the last trading day prior to the public
       announcement of the merger; and

    .  the exchange ratio in the merger of 0.6325 of a share of HP common stock
       for each share of Compaq common stock.

   Goldman Sachs calculated the implied exchange ratios by dividing the closing
prices per share of Compaq common stock for the relevant period of time, by the
closing prices per share of HP common stock for the same period. The results of
Goldman Sachs' implied exchange ratio analysis are presented in the table below
under the caption "Implied Exchange Ratio."

                                      67



   In connection with its historical exchange ratio analysis, Goldman Sachs
also calculated the extent to which the exchange ratio in the merger of 0.6325
of a share of HP common stock for each share of Compaq common stock exceeded,
on a percentage basis, each of the implied exchange ratios derived from
historical trading prices. The results of this analysis are presented in the
table below under the caption "Premium to Implied Exchange Ratio."

   Selected Companies Analysis.  Goldman Sachs also reviewed and compared the
revenue and price/earnings multiples of HP, Compaq and other selected public
companies in the computer hardware, services and storage industries for
calendar years 2001 and 2002, as well as the five-year compounded annual
Institutional Broker Estimate System growth rates and calendar year 2002
price/earnings/growth rate of HP, Compaq and the other selected public
companies. The other selected companies consisted of the following:

   .   Computer Hardware Industry: Apple, Dell, Gateway, IBM, Sun Microsystems

   .   Services Industry: Accenture, Computer Sciences, EDS, KPMG Consulting

   .   Storage Industry: EMC, Network Appliance

   The financial information and the revenue and price/earnings multiples were
derived from the closing prices of the common stock of each of the companies as
of August 31, 2001, and published analysts' reports and other publicly
available information. The results of Goldman Sachs' analysis are presented in
the table below:



                                                                          5-Year

   Goldman Sachs also calculated and compared the historical average forward
twelve month price/earnings ratio for HP and Compaq based on Wall Street
estimates provided by Institutional Brokers Estimate System. The following
table presents the results of this analysis.



                                                                      6 Months 1 Year 3 Years

   Goldman Sachs also analyzed the historical and estimated financial
information and multiples, which Goldman Sachs obtained from published
analysts' reports and estimates and other publicly available information,
presented in the table below. For purposes of the following comparison, Goldman
Sachs used Dell, Gateway, IBM and Sun as other selected companies.

   Synergies Analysis.  Goldman Sachs also reviewed the synergies estimates
that were presented to Goldman Sachs by the management of HP, which were
prepared after HP management had held discussions and exchanged information
with the management of Compaq (the "Synergies"). The Synergies reflect the
incremental benefits that the management of HP then expected to achieve as a
result of the merger, including cost savings and operating synergies. The
Synergies are based upon the assumption of HP management that HP and Compaq as
a combined company will begin to realize the benefits of these synergies in the
fourth quarter of HP's fiscal year 2002, but will not fully realize these
synergies until HP's fiscal year 2004. The analysis is based on the assumption
that synergies would be recognized in various business areas, including
administration, sales, cost of goods sold, research and development, marketing,
indirect purchasing and cost of services beginning in the fourth quarter of
fiscal year 2002.

   Goldman Sachs analyzed the Synergies by calculating the present value of the
future streams of after-tax cash flows to be generated by the Synergies and
applying discount rates reflecting, solely for purposes of this analysis, a
weighted average cost of capital ranging from 10% to 14%, to such after-tax
cash flows through HP's fiscal year 2006, and adding a terminal value
determined by projecting a range of nominal perpetual growth rates ranging from
0% to 4%. This analysis resulted in an estimated net present value for the
Synergies of approximately $11.3 billion to $24.5 billion, assuming that 100%
of the Synergies are actually realized. Based upon the exchange ratio in the
merger of 0.6325 of a share of HP common stock for each share of Compaq common
stock, the present value of the Synergies is between $3.66 and $7.92 per share
based on pro forma outstanding shares of common stock of the combined company.
The estimates of achievable cost synergies are based on numerous estimates,
assumptions and judgments and are subject to significant uncertainties. Actual
results may vary from the synergy estimates and the variations may be material.

   Pro Forma Merger Analysis.  Goldman Sachs also prepared pro forma analyses
of the financial impact of the merger using earnings projections based on Wall
Street estimates and earnings estimates and other information for HP and Compaq
prepared by their respective managements. This pro forma merger analysis is
based on HP management's estimates at the time the fairness opinion was
delivered of the future performance of the combined business. These estimates
take into account potential competitive responses to the merger by other

                                      69



companies in the computer hardware, services and storage industries as
perceived by HP management at the time such estimates were prepared. Goldman
Sachs performed these pro forma analyses assuming the following scenarios:

   (1) the combined company would derive no synergies and lose no revenue as a
       result of the merger during fiscal years 2002 and 2003;

   (2) the combined company would derive the Synergies from the merger and lose
       no revenue as a result of the merger during fiscal years 2002 and 2003;
       and

   (3) the combined company would derive the Synergies from the merger and lose
       $3,461 million in revenue in fiscal year 2002 and $1,786 million in
       revenue in fiscal year 2003 as a result of the merger.


   For each of the years 2002 and 2003, Goldman Sachs compared the estimated
earnings per share of HP common stock, on a standalone basis, to the earnings
per share of the common stock of HP and Compaq as a combined company on a pro
forma basis. The pro forma analysis was calculated based on pro forma cash
earnings per share, which excludes the impact of non-cash charges associated
with goodwill and intangible asset amortization. Goldman Sachs performed these
pro forma analyses assuming that the merger will be completed by May 1, 2002.
These analyses assume that synergy realization would start in the fourth
quarter of fiscal year 2002 and that potential revenue decreases related to the
merger would occur in UNIX(R) servers, NT servers, business PCs and home PCs
and that such revenue decreases would begin in the first quarter of fiscal year
2002 (beginning November 1, 2001). The results of these pro forma analyses are
presented below:


   .   Under scenario (1), the merger would be dilutive to HP shareowners on an
       earnings per share basis in year 2002 and significantly dilutive to HP
       shareowners on an earnings per share basis in year 2003.

   .   Under scenario (2), the merger would be significantly accretive to HP
       shareowners on an earnings per share basis in years 2002 and 2003.

   .   Under scenario (3), the merger would be dilutive to HP shareowners on an
       earnings per share basis in year 2002, and significantly accretive to HP
       shareowners on an earnings per share basis in year 2003.


   Specifically, the results of these pro forma analyses indicated that the
merger would be from 6.5% dilutive to 34.3% accretive to HP's earnings per
share in fiscal year 2003 relative to estimates of HP's fiscal year 2003
earnings per share available as of August 31, 2001.


   Other Considerations

   In connection with their consideration of the opinion rendered by Goldman
Sachs to the HP board of directors in connection with the merger, and the
summary of the analyses performed by Goldman Sachs described above, HP
shareowners should also consider the following matters.

   The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying the opinion rendered by Goldman Sachs to the HP board of directors
in connection with the merger. In arriving at its opinion as to the fairness of
the exchange ratio in the merger to HP, Goldman Sachs considered the results of
all of its analyses and did not attribute any particular weight to any factor
or analysis that it considered. Rather, Goldman Sachs made its determination on
the basis of its experience and professional judgment after considering the
results of all of the analyses it considered. No company or transaction used in
the analyses performed by Goldman Sachs as a comparison is directly comparable
to HP or Compaq or the transaction contemplated by the merger agreement. In
addition, Goldman Sachs prepared its analyses solely for purposes of rendering
an opinion to the HP board of directors as to the fairness from a financial
point of view to HP of the exchange ratio of 0.6325 of a share of HP common
stock to be exchanged for each share of Compaq common stock in connection with
the merger. The analyses that Goldman Sachs performed in connection with
rendering its opinion were not

                                      70



appraisals and do not necessarily reflect the prices at which businesses or
securities actually may be sold. In addition, analyses based upon forecasts of
future results are not necessarily indicative of actual future results, which
may be significantly more or less favorable than suggested by these analyses.
Because the analyses performed by Goldman Sachs in connection with rendering
its opinion are inherently subject to uncertainty, being based upon numerous
factors or events beyond the control of HP, Compaq or their respective
advisors, none of HP, Compaq, Goldman Sachs or any other person assumes
responsibility if future results are materially different from those forecast
or are not achieved in the time periods contemplated.

   The HP board of directors selected Goldman Sachs as its financial advisor in
connection with the merger because Goldman Sachs is an internationally
recognized investment banking firm that has substantial experience in
transactions that are similar to the merger. As part of its investment banking
business, Goldman Sachs is continually engaged in the valuation of businesses
and their securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements, and valuations for estate, corporate
and other purposes. Goldman Sachs is familiar with HP, having provided certain
investment banking services to HP from time to time that included having acted
as co-manager on the initial public offering of shares of common stock of
Agilent Technologies, Inc., an affiliate of HP at the time of the offering, in
November 1999, and as a manager of public offerings of debt securities of HP in
June 2000 (aggregate principal amount of $1.5 billion), July 2001 (aggregate
principal amount of (Euro)750 million) and August 2001 (aggregate principal
amount of $50 million), and having acted as HP's financial advisor in
connection with, and having participated in certain of the negotiations leading
to, the merger agreement. Goldman Sachs also has provided certain investment
banking services to Compaq from time to time.

   Goldman Sachs provides a full range of financial advisory and securities
services. From time to time in the course of its normal trading activities
Goldman Sachs may effect transactions and hold positions in the securities,
including derivative securities, of HP or Compaq for its own account and for
the accounts of customers. As of August 31, 2001, Goldman Sachs had accumulated
a net long position 451,315 shares of HP common stock, a net long position of
160,896 shares of Compaq common stock and a net long position of convertible
bonds of Compaq with an aggregate principal amount of $42.4 million.

   HP engaged Goldman Sachs to act as its financial advisor in connection with
the merger. The terms of HP's engagement agreement with Goldman Sachs provide
that HP will pay Goldman Sachs a transaction fee of $33 million, of which $5
million was payable upon execution of the merger agreement. The balance of the
fee will be payable upon completion of the merger. Under the terms of this
engagement agreement, HP also has agreed to reimburse Goldman Sachs for its
reasonable out-of-pocket expenses, including attorneys' fees, and to indemnify
Goldman Sachs against certain liabilities, including certain liabilities under
the federal securities laws.

Consideration of the Merger by the Compaq Board of Directors

   Recommendation of the Compaq Board of Directors

   At a meeting held on September 3, 2001, the Compaq board of directors
unanimously:

   .   determined that the merger is advisable, and fair to and in the best
       interests of Compaq and its shareowners;

   .   approved the merger agreement;

   .   directed that the proposed transaction be submitted for consideration by
       the Compaq shareowners at the Compaq special meeting; and

   .   resolved to recommend that the Compaq shareowners vote "for" the
       proposal to approve and adopt of the merger agreement and approve the
       merger.

                                      71



   In reaching its decision, the Compaq board of directors consulted with
Compaq's management, as well as its legal counsel and its financial advisor,
and considered the following material factors:


    (1) the reasons for the merger described in the section entitled "Reasons
        for the Merger" beginning on page 56 of this joint proxy
        statement/prospectus;


    (2) the merger will present, based on the then-current market price for HP
        common stock, the opportunity for the holders of Compaq common stock to
        receive a premium over the trading value of Compaq common stock on
        August 31, 2001, the last day of trading before public announcement of
        the proposed merger, while at the same time allowing Compaq shareowners
        to participate in a combined company positioned to benefit from new
        growth opportunities;

    (3) the Compaq board of directors' knowledge of Compaq and the industries
        in which the Compaq businesses compete and its belief that the greater
        resources which Compaq will realize as a result of the merger are
        important to the long-term future of Compaq;


    (4) the oral presentations by, and discussions with, Salomon Smith Barney
        and the written opinion of Salomon Smith Barney to the effect that, as
        of the date of the opinion, and based upon and subject to the
        considerations and limitations set forth in its opinion, its work
        described in the section entitled "Opinion of Compaq Financial Advisor"
        beginning on page 74 of this joint proxy statement/prospectus, its
        experience as investment bankers and other factors it deemed relevant,
        the exchange ratio provided for in the merger agreement is fair, from a
        financial point of view, to the holders of Compaq common stock. A copy
        of Salomon Smith Barney's written opinion is attached to this joint
        proxy statement/prospectus as Annex C;


    (5) the fact that the merger provides for a fixed exchange ratio and, as a
        result, the value of HP common stock to be received by Compaq
        shareowners upon completion of the merger may be higher or lower than
        the value of such stock at the time the merger agreement was signed;

    (6) historical information concerning HP's and Compaq's respective
        businesses, prospects, financial performance and condition, operations
        technology, management and competitive position, including public
        reports concerning results of operations during the most recent fiscal
        year and fiscal quarter for each company as filed with the Securities
        and Exchange Commission;

    (7) the strength of the management team of the combined company, including
        the addition of Michael Capellas as president of the combined company;

    (8) the ability to complete the merger as a reorganization for United
        States federal income tax purposes in which Compaq shareowners
        generally will not recognize any gain or loss, except for any gain or
        loss recognized in connection with cash received for a fractional share
        of HP's common stock;

    (9) the Compaq board of directors' belief, after considering the advice of
        counsel, that the parties should be able to satisfy all conditions to
        the completion of the merger, including the receipt of the necessary
        regulatory approvals in accordance with the terms of the merger
        agreement, while recognizing the possibility that regulators might
        impose conditions on the grant of their approval;

   (10) the prospects of Compaq as an independent company;

   (11) the terms of the merger agreement regarding third party proposals,
        including (a) that the Compaq board of directors may, under certain
        circumstances, furnish information to a party making, and enter into
        discussions regarding, a proposal that the Compaq board of directors
        concludes in good faith could result in a superior proposal, (b) that
        the Compaq board of directors may not withdraw or change its
        recommendation of the merger after receiving a superior proposal, (c)
        the potential payment to HP of a termination fee, and (d) the potential
        effect of such provisions on possible efforts by other parties to
        acquire or otherwise combine with Compaq;

   (12) the fact that Compaq shareowners will have an opportunity to vote on
        the proposed merger; and

                                      72




   (13) the interests that certain executive officers and directors of Compaq
        may have with respect to the merger in addition to their interests as
        shareowners of Compaq generally. See the section entitled "Interests of
        Compaq Directors and Executive Officers in the Merger" beginning on
        page 86 of this joint proxy statement/prospectus.


   In reaching its determination, the Compaq board of directors considered the
factors described above generally figured positively, as advantages or
opportunities, with the exception of the factor described in clause (11) above,
which figured both positively and negatively, and the factors described in
clauses (5) and (13) above, which the Compaq board of directors considered to
be neutral. The Compaq board of directors also identified and considered the
following potentially negative material factors in its deliberations concerning
the merger:

   (1) the risk that the potential benefits sought in the merger might not be
       fully realized;

   (2) the challenges of integrating the management teams, strategies, cultures
       and organizations of the companies while both companies are currently
       restructuring their respective businesses;

   (3) the risk that despite the efforts of the combined company, key
       management and other personnel might not remain employed by the combined
       company;

   (4) risks associated with fluctuations in HP's stock price and Compaq's
       stock price prior to completion of the merger;

   (5) the risk of disruption of sales momentum as a result of uncertainties
       created by the announcement of the merger;

   (6) the possibility that the merger might not be completed, even if approved
       by each company's shareowners, including the possible effect of the
       termination fee;

   (7) the effect of the public announcement of the merger, and the possibility
       that the merger might not be completed, on demand for Compaq's products
       and services, Compaq's relationships with strategic partners, Compaq's
       operating results, Compaq's stock price and Compaq's ability to attract
       and retain key management and marketing, sales, technical and other
       personnel;

   (8) the substantial charges to be incurred in connection with the merger,
       including costs of integrating the businesses and transaction expenses
       arising from the merger; and


   (9) other applicable risks described in the section entitled "Risk Factors"
       beginning on page 23 of this joint proxy statement/prospectus.


   The Compaq board of directors believed that these risks were outweighed by
the potential benefits of the merger.

   The Compaq board of directors did not find it necessary to, and did not
quantify or otherwise assign relative weights to, the foregoing factors or
determine that any factor was of particular importance. Rather, the Compaq
board of directors views its recommendation as being based on the totality of
the information presented to, and considered by, it. The Compaq board of
directors considered all these factors and determined that these factors, as a
whole, supported the conclusions and recommendations described above.


   In considering the recommendation of the Compaq board of directors to
approve and adopt the merger agreement and approve the merger, Compaq
shareowners should be aware that certain officers and directors of Compaq have
certain interests in the proposed merger that are different from and in
addition to the interests of Compaq shareowners generally. The Compaq board of
directors was aware of these interests and considered them in approving the
merger agreement and the merger. See the section entitled "Interests of Compaq
Directors and Executive Officers in the Merger" beginning on page 86 of this
joint proxy statement/prospectus.


                                      73



   Opinion of Compaq Financial Advisor

   Salomon Smith Barney was retained to act as financial advisor to Compaq in
connection with the merger. Pursuant to Salomon Smith Barney's engagement
letter with Compaq, Salomon Smith Barney rendered a written opinion to the
Compaq board of directors on September 3, 2001, to the effect that, based upon
and subject to the assumptions, considerations and limitations set forth in its
opinion, its work described below, its experience as investment bankers and
other factors it deemed relevant, as of that date, the exchange ratio was fair,
from a financial point of view, to holders of Compaq common stock.

   The Salomon Smith Barney opinion and the presentation of Salomon Smith
Barney to the Compaq board of directors, in connection with which Salomon Smith
Barney was requested to evaluate the fairness, from a financial point of view,
of the exchange ratio to the holders of Compaq common stock, was one of many
factors taken into consideration by the Compaq board of directors in making its
decision to approve the merger agreement. The terms of the merger were
determined through negotiations between Compaq and HP, and were approved by the
Compaq board of directors. Although Salomon Smith Barney provided advice to
Compaq during the course of negotiations, the decision to enter into the merger
agreement and to agree to the exchange ratio was solely that of the Compaq
board of directors.

   The full text of Salomon Smith Barney's opinion, which sets forth the
assumptions made, general procedures followed, matters considered and
limitations on the review undertaken by Salomon Smith Barney, is attached to
this joint proxy statement/prospectus as Annex C. The summary of Salomon Smith
Barney's opinion set forth below is qualified in its entirety by reference to
the full text of the opinion. Shareowners are urged to read Salomon Smith
Barney's opinion carefully and in its entirety.

   Salomon Smith Barney has consented to the inclusion of its opinion and to
the inclusion of the summary of its opinion in this joint proxy
statement/prospectus. In giving such consent, Salomon Smith Barney does not
concede that it comes within the category of persons whose consent is required
under Section 7 of the Securities Act of 1933, or the rules and regulations of
the Securities and Exchange Commission thereunder, nor does it concede that it
is an expert within the meaning of the term "expert" as used in the Securities
Act of 1933 or the rules and regulations of the Securities and Exchange
Commission thereunder with respect to any part of the registration statement on
Form S-4 of which this joint proxy statement/prospectus forms a part.

   In connection with rendering its opinion, Salomon Smith Barney, among other
things:

    .  reviewed a draft of the merger agreement dated September 3, 2001;

    .  held discussions with certain senior officers and other representatives
       and advisors of Compaq and HP concerning the businesses, operations and
       prospects of Compaq and HP;

    .  examined publicly available business and financial information relating
       to Compaq and HP and the industries in which they operate;

    .  reviewed financial forecasts and information relating to certain
       strategic implications and operational benefits anticipated to result
       from the merger and other information and data regarding Compaq and HP
       that were provided to or otherwise discussed with it by management of
       Compaq and HP;

    .  reviewed the financial terms of the merger as set forth in the draft
       merger agreement provided to it in relation to, among other things,
       current and historical market prices and trading volumes of Compaq
       common stock and HP common stock, the historical and projected earnings
       and other operating data of Compaq and HP, and the historical and
       projected capitalization and financial condition of Compaq and HP;

    .  considered, to the extent publicly available, the financial terms of
       other similar transactions recently effected or proposed which Salomon
       Smith Barney considered relevant in evaluating the merger; and analyzed
       certain financial, stock market, economic and other publicly available
       information relating to

                                      74



       the businesses of other companies whose operations Salomon Smith Barney
       considered relevant in evaluating those of Compaq and HP; and

    .  conducted such other analyses and examinations and considered such other
       information and financial, economic and market criteria as Salomon Smith
       Barney deemed appropriate in arriving at its opinion.

   In its review and analysis and in arriving at its opinion, Salomon Smith
Barney assumed and relied upon, without assuming any responsibility for
independent verification, the accuracy and completeness of all of the financial
and other information and data publicly available or furnished to, discussed
with or otherwise reviewed by or for it. With respect to financial forecasts
and information relating to certain strategic implications and operational
benefits anticipated to result from the merger provided to or otherwise
reviewed by or discussed with Salomon Smith Barney regarding Compaq and HP,
Salomon Smith Barney was advised by the management of Compaq and HP that such
forecasts and other information had been reasonably prepared on bases
reflecting the best then currently available estimates and judgments of Compaq
and HP management, as the case may be. Salomon Smith Barney assumed that such
operational benefits would be realized in the amounts and during the time
periods contemplated by management. Salomon Smith Barney expressed no view with
respect to such forecasts and other information or the assumptions on which
they were based. Salomon Smith Barney assumed that the merger will be treated
as a tax-free reorganization for United States federal income purposes. Salomon
Smith Barney did not make and was not provided with an independent evaluation
or appraisal of the assets or liabilities (contingent or otherwise) of Compaq
or HP, nor did it make any physical inspection of the properties or assets of
Compaq or HP.

   Salomon Smith Barney assumed that the representations and warranties of each
party contained in the merger agreement were true and correct in all material
respects and that each party will perform all of the covenants and agreements
required to be performed by it under the merger agreement. Compaq advised
Salomon Smith Barney, and Salomon Smith Barney assumed, that the final terms of
the merger agreement would not vary materially from those set forth in the
draft provided to it. Salomon Smith Barney further assumed that the merger
would be consummated in accordance with the terms of the merger agreement
without waiver of any of the conditions precedent to the merger contained in
the merger agreement. Salomon Smith Barney also assumed that all material
governmental, regulatory and other consents and approvals will be obtained and
that in the course of obtaining any necessary governmental, regulatory and
other consents and approvals, or any amendments, modifications or waivers to
any documents to which either Compaq or HP is a party, no restrictions will be
imposed or amendments, modifications or waivers made that would have any
material adverse effect on its analysis.

   Salomon Smith Barney's opinion relates to the relative values of Compaq and
HP. It does not imply any conclusion as to the likely trading range for Compaq
common stock or HP common stock following the announcement or consummation of
the merger, which range may vary depending upon, among other factors, changes
in interest rates, dividend rates, market conditions, general economic
conditions and other factors that generally influence the price of securities.
Salomon Smith Barney was not requested to consider, and its opinion did not
address, the relative merits of the merger as compared to any alternative
business strategies that might exist for Compaq or the effect of any other
transaction in which Compaq might engage. Salomon Smith Barney's opinion
necessarily was based on information available to it and financial, stock
market, economic and other conditions and circumstances disclosed to it as they
existed and could be evaluated as of the date of its opinion. Salomon Smith
Barney assumed no responsibility to update or revise its opinion based on
circumstances or events occurring after September 3, 2001.

   Salomon Smith Barney's advisory services and opinion were provided for the
information of Compaq's board of directors in its evaluation of the proposed
merger and do not constitute a recommendation of the merger to Compaq or its
shareowners, nor do they constitute a recommendation to any shareowner as to
how such shareowner should vote on any matter relating to the merger.

                                      75



   In connection with rendering its opinion, Salomon Smith Barney made
presentations to the Compaq board of directors on August 30, 2001 and on
September 3, 2001, with respect to the material financial and comparative
analyses performed by Salomon Smith Barney in evaluating the fairness of the
exchange ratio. The following is a summary of those presentations. This summary
does not purport to be a complete description of the analyses performed by
Salomon Smith Barney. The summary includes information presented in tabular
format. In order to understand fully the financial analyses used by Salomon
Smith Barney, these tables must be read together with the text of each summary.
The tables alone do not constitute a complete description of the financial
analyses. The following quantitative information, to the extent it is based on
market data, is, except as otherwise indicated, based on market data as it
existed at or prior to September 3, 2001, and is not necessarily indicative of
current or future market conditions. All calculations, forecasts and estimates
set forth with respect to a specific year are based on such calendar year and
not the fiscal year unless otherwise indicated.

   Relative Historical Stock Price Performance

   Salomon Smith Barney reviewed the relationship between movements of the
Compaq common stock, the HP common stock and the Nasdaq Composite Index for the
period from and including July 3, 2000 through August 7, 2001, the average
closing prices for the Compaq common stock and the HP common stock over various
periods during the 12-month period ended August 31, 2001 and the trading volume
and price history of the Compaq common stock and the HP common stock for the
period ended August 31, 2001.

   Historical Exchange Ratio Analysis

   Salomon Smith Barney reviewed the historical exchange ratio between the
Compaq common stock and the HP common stock. The exchange ratios used in the
analysis were determined by dividing the closing price per share of Compaq
common stock by the closing price per share of HP common stock on each day over
the 12-month period ended August 31, 2001, the last trading day prior to the
public announcement of the merger. Salomon Smith Barney then examined certain
averages of the historical exchange ratios over various periods during such
12-month period. Salomon Smith Barney also determined an implied premium that
the proposed exchange ratio of 0.6325 of a share of HP common stock for each
share of Compaq common stock represented over the historical exchange ratio for
each period. This review indicated the following historical exchange ratios and
implied premiums:



                                                            Average

   Comparable Public Market Valuation Analysis

   Using stock prices as of August 31, 2001 and publicly available information
regarding Compaq and HP as well as Wall Street consensus forecasts and
estimates regarding the two companies discussed with management, Salomon Smith
Barney compared Compaq and HP to a selected group of companies using various
measures of financial performance. The eight companies that Salomon Smith
Barney used in its analysis are:

   .   Dell Computer Corp.;

   .   Gateway, Inc.;

                                      76

   .   Apple Computer, Inc.;

   .   International Business Machines Corp.;

   .   Lexmark International, Inc.;

   .   NCR Corp.; and

   .   Unisys Corp.

   Firm value calculations were made based on the closing price per share of
each company's common stock on August 31, 2001.

   Salomon Smith Barney noted that Compaq's and HP's firm values as multiples
of revenues for the 12-month period ended June 30, 2001 (LTM) were 0.5x and
1.0x, respectively. Firm values as multiples of LTM revenues for the selected
companies ranged from 0.2x to 2.1x. Salomon Smith Barney further noted that
Compaq's and HP's firm values as multiples of LTM earnings before interest
expense, taxes, depreciation and amortization (EBITDA) were 5.7x and 12.4x,
respectively. Firm values as multiples of LTM EBITDA for the selected companies
ranged from 5.3x to 18.2x. Salomon Smith Barney also noted that Compaq's and
HP's firm values as multiples of LTM earnings before interest expenses and
taxes (EBIT) were 9.8x and 19.8x, respectively. Firm values as multiples of LTM
EBIT for the selected companies ranged from 8.9x to 19.9x.



                                               Firm Values as a Multiple of:

Selected Group..............................  0.2x-2.1x  5.3x-18.2x 8.9x-19.9x


   Salomon Smith Barney also noted that Compaq's and HP's multiples of stock
price to estimated 2001 earnings per share ("EPS") were 34.3x and 35.7x,
respectively, using the closing price for each company's common stock on August
31, 2001. Multiples of stock prices to estimated 2001 EPS for the eight
selected companies ranged from 18.5x to 57.3x, using the closing price for each
company's stock on August 31, 2001. Salomon Smith Barney further noted that
Compaq's and HP's multiples of stock prices to estimated 2002 EPS were 18.4x
and 19.2x, respectively. Multiples of stock prices to estimated 2002 EPS for
the eight selected companies ranged from 10.7x to 27.1x. Salomon Smith Barney
also noted that Compaq's and HP's multiples of stock prices to estimated 2003
EPS were 14.0x and 12.5x, respectively. Multiples of stock prices to estimated
2003 EPS for the eight selected companies ranged from 9.3x to 19.5x.



                                   Closing Stock Price on August 31, 2001

                                      77



   Similar Transactions Premium Analysis

   Salomon Smith Barney reviewed publicly available information regarding
selected announced or completed stock-for-stock transactions with an announced
value in excess of $10 billion and for which the acquired company's:

   .   board members would have significant representation on the board of
       directors of the combined entity;

   .   executive management would have meaningful management roles in the
       combined entity; and

   .   shareowners would retain a significant pro forma ownership in the
       combined entity.

   The transactions that Salomon Smith Barney used in its analysis included the
following combinations:

   .   Halifax Group's combination with the Royal Bank of Scotland (announced
       May 2001);

   .   Chevron Corporation's combination with Texaco, Inc. (announced October
       2000);

   .   The Chase Manhattan Corporation's combination with JP Morgan & Co., Inc.
       (announced September 2000);

   .   El Paso Energy Corporation's combination with The Coastal Corporation
       (announced January 2000);

   .   CGU plc's combination with Norwich Union (announced January 2000);

   .   MCI WorldCom Inc.'s proposed combination with Sprint Corporation
       (announced October 1999);

   .   Clear Channel Communications, Inc.'s combination with AMFM Inc.
       (announced October 1999);

   .   Exxon Corporation's combination with Mobil Corporation (announced
       December 1998);

   .   The British Petroleum Company p.l.c.'s combination with Amoco
       Corporation (announced August 1998);

   .   SBC Communications Inc.'s combination with Ameritech Corporation
       (announced May 1998);

   .   NationsBank Corporation's combination with BankAmerica Corporation
       (announced April 1998);

   .   Banc One Corporation's combination with First Chicago NBD Corporation
       (announced April 1998); and

   .   Bell Atlantic Corporation's combination with NYNEX Corporation
       (announced April 1996).

   Using publicly available information for each selected transaction, Salomon
Smith Barney calculated the premium provided by the transaction over the
implied exchange ratio based on the two companies' average closing prices per
common share for the 10 trading days prior to the announcement of the
transaction and for the 20 trading days prior to announcement. Salomon Smith
Barney's analysis resulted in a range of premiums of (8)% to 46% over exchange
ratios implied by average prices for the 10 trading days prior to announcement,
with a median premium of 23%. Salomon Smith Barney's analysis further resulted
in a range of premiums of (7)% to 58% over exchange ratios implied by average
prices for the 20 trading days prior to announcement, with a median premium of
23%. Using publicly available information for each selected transaction,
Salomon Smith Barney also calculated the premium provided by the transaction
based on the acquiring company's closing price one day prior to the
announcement of the transaction. Salomon Smith Barney's analysis resulted in a
range of premiums of (12)% to 29%, with a median premium of 15%.

   Based on its analysis, Salomon Smith Barney determined a range of implied
exchange ratios of 0.585x to 0.680x by applying the range of premiums for other
transactions to the closing prices of Compaq and HP on August 31, 2001 and the
average historical exchange ratio for Compaq and HP for the 10-day period
ending on August 31, 2001, as appropriate.

   Synergies

   Salomon Smith Barney reviewed the synergy estimates provided by the
management of Compaq. The synergy estimates were prepared by Compaq management
and its consultants to reflect the incremental benefits anticipated to result
from the merger, including cost savings and operating synergies. The synergies
were prepared based on the assumptions that synergies would arise through the
development of new retail programs in the consumer PC product area and through
savings in sales and marketing, in manufacturing, logistics and procurement, in
research and development, and in support functions. This analysis did not
include potential revenue loss resulting from the merger. This analysis used
forecasts of estimated cash flow effects of assumed synergies (net of
restructuring charges) of $1.3 billion in the first full year of combined
operations after the merger, $2.5 billion in the second full year of combined
operations after the merger, $2.9 billion in the third full year of combined
operations after the merger and $3.1 billion annually thereafter.

   Salomon Smith Barney estimated the present value of the anticipated cash
flow effect of the estimated synergies as of the transaction closing date, by
applying discount rates reflecting a weighted average cost of capital ranging
from 12.5% to 13.5% per annum to cash flow effects for a five-year period after
the date of completion of the transaction and by adding a terminal value
determined by applying an EBIT multiple of 13.5x to 14.5x. This analysis
resulted in a range of present values for Compaq common shareowners'
proportionate share of the synergies of $28.3 billion to $31.2 billion,
representing a range of synergy value per share of Compaq common stock from
approximately $5.96 to $6.56. The estimates of achievable synergies and timing
of the realization of such synergies are based on numerous estimates,
assumptions and judgments and are subject to significant uncertainties. Actual
results may vary from the synergy estimates and the variations in amounts and
timing may be material.

   Contribution Analysis

   Salomon Smith Barney performed an analysis comparing the relative
contributions of Compaq and HP to the combined pro forma company. Using stock
prices as of August 31, 2001 and publicly available information regarding
Compaq and HP as well as Wall Street consensus forecasts and estimates
regarding the two companies discussed with management, Salomon Smith Barney
reviewed each company's relative contribution to the combined company's actual
LTM and estimated 2001, 2002 and 2003 revenues, EBIT and net income, as well as
the combined company's fully-diluted equity value as of August 31, 2001 and
derived a range of implied exchange ratios from such contributions. The
following table sets forth the results of Salomon Smith Barney's review.

   Based on its analysis, Salomon Smith Barney determined a range of Compaq's
percentage contributions to (1) EBIT of 35% to 40%, which corresponds to a
range of implied exchange ratios of 0.617x to 0.764x and (2) net income of 30%
to 33%, which corresponds to a range of implied exchange ratios of 0.491x to
0.565x. In presenting this information to the Compaq board of directors,
Salomon Smith Barney noted that the proposed exchange ratio of 0.6325 was
within the ranges of implied exchange ratios derived from its EBIT contribution
analysis and higher than the range derived from its net income contribution
analysis. Salomon Smith Barney informed the board that it considered the range
of implied exchange ratios derived from revenues contribution to be less
relevant than the ranges derived from EBIT and net income because HP and
Compaq's different business sectors have significantly varying profit margins,
thus making a revenue comparison less accurate in reflecting the contribution
of each company to the combined entity's value.

   Precedent Industry Transaction Valuation Analysis

   Salomon Smith Barney reviewed and analyzed certain financial, operating and
stock market information relating to the following six selected transactions
involving companies in the computer systems, services, hardware and/or server
sectors:

   .   International Business Machine Corp.'s acquisition of Sequent Computer
       Systems, Inc. (announced July 1999);

   .   Ascend Communications, Inc.'s acquisition of Stratus Computer Inc.
       (announced August 1998);

   .   Compaq's acquisition of Digital Equipment Corporation (announced January
       1998);

   .   Compaq's acquisition of Tandem Computers Incorporated (announced June
       1997);

   .   Gateway, Inc.'s acquisition of Advanced Logic Research, Inc. (announced
       June 1997); and

   .   Samsung Electronics Co., Ltd.'s acquisition of AST Research, Inc.
       (announced January 1997).

   Salomon Smith Barney reviewed the multiples of firm value to revenues and
EBITDA for the twelve months preceding the announcement of each of the selected
transactions. Multiples of firm value to such revenues ranged from 0.24x to
1.55x, with an average of 0.80x. Multiples of firm value to such EBITDA ranged
from 4.1x to 11.5x, with an average of 8.7x.

   Based on its analysis, Salomon Smith Barney determined a range of implied
exchange ratios of 0.637x to 0.863x, using HP's 10-day average closing share
price for the period ending August 31, 2001. Salomon Smith Barney indicated to
the Compaq board of directors that the precedent transactions utilized in this
analysis were acquisitions and generally did not include provisions granting
the acquired company's board of directors and executive management meaningful
and significant roles in the combined entity. In addition, the target was
substantially smaller than the acquiror in many of the precedent industry
transactions and, except for the Ascend/Stratus and Compaq/Tandem transactions,
none of the precedent industry transactions was an entirely stock-for-stock
transaction. Therefore, although such transactions featured companies in
similar lines of business as Compaq, they were not directly comparable to the
merger. Although Salomon Smith Barney indicated to the Compaq board that it
took the results of this analysis into account in evaluating the fairness of
the exchange ratio, it informed the board that it considered the results of
this analysis to be less significant and relevant in its fairness evaluation.

   Pro Forma Earnings Per Share Impact to Compaq

   Using stock prices as of August 31, 2001 and publicly available information
regarding Compaq and HP as well as Wall Street consensus forecasts and
estimates regarding the two companies discussed with management, Salomon Smith
Barney performed an analysis of the estimated impact of the merger on estimated
Compaq EPS for 2002 and 2003, in each case on a pro forma basis, for a
combination as if effected on January 1, 2002. For illustrative purposes,
Salomon Smith Barney also assumed that the estimated first full year of pre-tax
synergies

                                      80



of $2.1 billion (excluding restructuring charges) would be realized in the 2002
calendar year and the second full year of pre-tax synergies of $2.9 billion
(excluding restructuring charges) would be realized in the 2003 calendar year.
The estimates of achievable cost synergies and the timing of the realization of
such cost synergies are based on numerous estimates, assumptions and judgments
and are subject to significant uncertainties. Actual results may vary from the
synergy estimates and the variations in amounts and timing may be material.
Based on this analysis, the following table shows the accretion/dilution to the
estimated 2002 and 2003 EPS of Compaq anticipated to result from the merger:



                                                                    EPS   EPS

   Salomon Smith Barney also performed a synergy sensitivity analysis on the
results of its earnings impact analysis by varying the amount of pre-tax
synergies for the first and second calendar years after the completion of the
merger from zero to $3.0 billion per year. Based on this analysis, the
following table shows the accretion/dilution to the estimated 2002 and 2003 EPS
of Compaq anticipated to result from the merger for varying ranges of assumed
synergies:

   Other Considerations

   The preceding discussion is a summary of the material financial analyses
furnished by Salomon Smith Barney to the Compaq board of directors, but it does
not purport to be a complete description of the analyses performed by Salomon
Smith Barney or of its presentation to the Compaq board of directors. The
preparation of financial analyses and fairness opinions is a complex process
involving subjective judgments and is not necessarily susceptible to partial
analysis or summary description. Salomon Smith Barney made no attempt to assign
specific weights to particular analyses or factors considered, but rather made
qualitative judgments as to the significance and relevance of all the analyses
and factors considered and determined to give its fairness opinion as described
above. Accordingly, Salomon Smith Barney believes that its analyses, and the
summary set

                                      81




forth above, must be considered as a whole, and that selecting portions of the
analyses and of the factors considered by Salomon Smith Barney, without
considering all of the analyses and factors, could create a misleading or
incomplete view of the processes underlying the analyses conducted by Salomon
Smith Barney and its opinion. With regard to the comparable companies and
similar and precedent transaction analyses summarized above, Salomon Smith
Barney selected comparable companies and similar and precedent transactions on
the basis of various factors, including size, similarity of line of business
and terms of transactions; however, no company utilized in these analyses is
identical to Compaq or HP and no precedent transaction is identical to the
merger. As a result, these analyses are not purely mathematical, but also take
into account differences in financial and operating characteristics of the
subject companies and other factors that could affect the transaction or public
trading value of the subject companies to which Compaq and HP are being
compared. In addition, although the precedent industry transactions analysis
featured companies in similar lines of business as Compaq, they were not
directly comparable to the merger and, accordingly, Salomon Smith Barney
considered the results of its precedent industry transaction valuation analysis
to be less significant and relevant in its fairness evaluation. In its
analyses, Salomon Smith Barney made numerous assumptions with respect to
Compaq, HP, industry performance, general business, economic, market and
financial conditions and other matters, many of which are beyond the control of
Compaq and HP. Any estimates contained in Salomon Smith Barney's analyses are
not necessarily indicative of actual values or predictive of future results or
values, which may be significantly more or less favorable than those suggested
by these analyses. Estimates of values of companies do not purport to be
appraisals or necessarily to reflect the prices at which companies may actually
be sold. Because these estimates are inherently subject to uncertainty, none of
Compaq, HP, the Compaq board of directors, the HP board of directors, Salomon
Smith Barney or any other person assumes responsibility if future results or
actual values differ materially from the estimates or are not achieved during
the time periods contemplated. Salomon Smith Barney's analyses were prepared
solely as part of Salomon Smith Barney's analysis of the fairness of the
exchange ratio in the merger and were provided to the Compaq board of directors
in that connection. The opinion of Salomon Smith Barney was only one of the
factors taken into consideration by the Compaq board of directors in making its
determination to approve the merger agreement and the merger. Please see the
section entitled "Recommendation of the Compaq Board of Directors" beginning on
page 71 of this joint proxy statement/prospectus.


   Salomon Smith Barney is an internationally recognized investment banking
firm engaged in, among other things, the valuation of businesses and their
securities in connection with mergers and acquisitions, restructurings,
leveraged buyouts, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. Compaq selected Salomon
Smith Barney to act as its financial advisor on the basis of Salomon Smith
Barney's international reputation and Salomon Smith Barney's familiarity with
Compaq. Salomon Smith Barney and its predecessors and affiliates have
previously provided and currently are providing investment banking services to
Compaq unrelated to the merger, for which Salomon Smith Barney has received and
will receive compensation. Since August 2000, Salomon Smith Barney has advised
Compaq with respect to Compaq's purchase of certain configuration and
distribution assets from InaCom Inc. and has acted as an underwriter or a
manager of public offerings of debt securities of Compaq in August 2000
(aggregate principal amount of $575 million), and May 2001 (aggregate principal
amount of $300 million). Since June 2000, Salomon Smith Barney also acted as an
underwriter or a manager in offerings of debt securities of HP in June 2000
(aggregate principal amount of $1.5 billion), July 2001 (aggregate principal
amount of up to (Euro)750 million) and December 2001 (aggregate principal
amount of $1 billion).

   In the ordinary course of its business, Salomon Smith Barney and its
affiliates may actively trade or hold the securities of both Compaq and HP for
its own account and for the account of customers and, accordingly, may at any
time hold a long or short position in those securities. Salomon Smith Barney
and its affiliates, including Citigroup Inc. and its affiliates, may maintain
relationships with Compaq and HP and their respective affiliates. As of
September 30, 2001, Citigroup Inc. and its affiliates held for their own
accounts approximately 10.5 million shares of common stock of Compaq and 23.4
million shares of common stock of HP.

                                      82



   Pursuant to the terms of an engagement letter, Compaq agreed to pay Salomon
Smith Barney the following fees for its services rendered in connection with
the merger:

   .   $500,000 payable upon the signing of the engagement letter;

   .   $9,500,000 payable upon the execution of the merger agreement; and

   .   an amount equal to 0.25% of the aggregate consideration received by the
       holders of Compaq common stock in the proposed merger (less the
       $10,000,000 described in the previous clauses).

   Compaq also has agreed to reimburse Salomon Smith Barney for its reasonable
travel and other expenses incurred in connection with its engagement, including
the reasonable fees and expenses of its outside counsel, and to indemnify
Salomon Smith Barney against specific liabilities and expenses relating to or
arising out of its engagement, including liabilities under the federal
securities laws.

Interests of HP and Compaq Directors and Executive Officers in the Merger

    Interests of HP Directors and Executive Officers in the Merger

   Certain members of the management of HP and some of the HP board of
directors have interests in the merger that may be different from, or in
addition to, the interests of the other shareowners of HP generally. These
interests are summarized below.

   Retention and Severance Arrangements

   The success of the combined company following the merger will be determined
in part by how effectively the combined company will be able to successfully
create a unified workforce--including a management team--drawn from the
existing talent of both HP and Compaq. Many of the decisions regarding business
integration, organizational structure and the leadership team of the combined
company may not be made or announced until shortly before or after the
completion of the merger. The resulting uncertainty could lead some of HP's key
employees, including executives, to accept other employment opportunities. To
address this concern, as is customary for transactions similar to the merger
and necessary to keep key employees focused during a transition period, the
compensation committee of the HP board of directors (consisting of Messrs.
Condit, Ginn and Hewlett), acting on the authority of the full board, adopted a
retention program. The retention program is designed to assure the continued
dedication of key employees, including some senior managers, during this
uncertain period. The program provides incentives to a group of employees
considered critical to the completion of the merger, to the integration of the
companies, or to ongoing business operations. In addition, the program is
designed to enable the participating employees to focus on ensuring the success
of the merger, to minimize workforce disruption and to maximize the value of
the combined company in the future.

   The compensation committee adopted a retention program that includes the
payment of retention bonuses to specified employees of HP that are contingent
upon the completion of the merger. Ms. Fiorina would have been entitled to
receive retention bonuses under this program totaling two times the sum of her
current salary and target annual bonus (a total of $8.0 million), but she has
declined to accept the right to participate in this program. Other executive
officers of HP may receive the following retention payments under this program
as follows: (1) three times current salary plus target bonus for Ms. Livermore,
Mr. Wayman, Mr. Zitzner, Susan D. Bowick, HP's Vice President and Director,
Corporate Human Resources, Vyomesh Joshi, HP's President, Imaging and Printing
Systems, Pradeep Jotwani, HP's President, Consumer Business Organization, Webb
McKinney, HP's President, Business Customer Organization, and Iain M. Morris,
HP's President, Embedded and Personal Systems, in each case payable in two
equal installments, with the first installment payable on September 4, 2002 and
the second installment payable on September 4, 2003, and (2) two times current
salary plus target bonus for Debra L. Dunn, HP's Vice President, Strategy and
Corporate Operations, and Jon E. Flaxman, HP's Corporate Controller, in each
case payable in two equal installments, with the first installment payable upon
completion of the merger and the second installment payable on the first
anniversary of the

                                      83



completion. The aggregate amount of the retention payments for the
participating executive officers, should they all remain employed until payment
of the second installment of their retention bonuses, will total approximately
$33.1 million.

   The compensation committee of HP's board of directors (consisting of Messrs.
Condit, Ginn and Hewlett) determined that it was important in order to ensure a
smooth transition that the retention program be selective but broad-based and
extend beyond HP's executive officers to a number of key employees throughout
the company. The retention payments to these key employees, the majority of
which are individual contributors and mid-level managers, are approximately 0.5
times their current salary plus target bonus, on average. The payments are
generally payable in two equal installments, the first payable upon the
completion of the merger and the second payable on the first anniversary of the
completion of the merger, assuming the recipient is still employed by HP at
that time. It is expected that approximately 6,000 HP employees will
participate in the program and that total payments for the non-executive
officers, if paid in full, will be approximately $168.5 million in each of the
fiscal years in which the payments may come due. If the merger does not close,
no payments will be made under the program.

   As a part of its retention program, HP also agreed to provide its ten
executive officers who are receiving retention bonuses as described above
certain payments and benefits in the event of a "qualifying termination" within
two years after the completion date of the merger. A qualifying termination is
defined as any termination by HP other than for cause, resignation of the
executive for good cause (including a reduction in the executive's total salary
plus target bonus, a reduction of the executive's base salary or a material
reduction in the kind or level of the executive's employee benefits) or
termination of the executive for disability. In the event of a qualifying
termination within two years after the completion of the merger, the executive
will become entitled to the following payments and benefits, offset by any
retention payments described above previously paid to the executive:

   .   a cash payment equal to 1.5 times the executive's then-current base
       salary plus target bonus;

   .   the executive's stock options will become fully exercisable and will
       remain exercisable until the earlier of:

       -  the third anniversary of the executive's termination date; and

       -  the expiration of the term of the stock option;

   .   any unvested restricted stock granted to the executive under HP's stock
       plans will vest and a portion of other restricted stock held by the
       executive will vest; and

   .   continuation of certain health benefits.


   The retention bonuses operate to provide incentives to stay with the
post-merger entity because executive officers and other participants will be
financially better off if they remain with the combined company following the
merger through the relevant payment dates for retention bonuses. Under the
retention program, eight of the executive officers will receive 1.5 times their
current salary plus target bonus if they remain employed by HP until September
4, 2002. If HP terminates their employment prior to September 4, 2002, in an
event that is a "qualifying termination" as described above, they would receive
1.5 times their base salary and target bonus as well as other benefits
described above. They will therefore have an incentive not to resign
voluntarily, because in that case they would not receive a payment under either
program. In addition, these executive officers will receive 1.5 times their
salary and target bonus if they remain employed through September 4, 2003. If
HP terminates their employment in a qualifying termination after September 4,
2003, the amount that they would have been entitled to receive under the
severance program will be offset entirely by amounts previously paid under the
retention program. Two of the executive officers will receive one times their
current salary plus target bonus upon completion of the merger, and one times
their current salary upon the one year anniversary of the completion of the
merger if they remain employed by HP as of that date, which amounts would be
offset against any severance payments received under the retention program,
leading to similar incentives to those described


                                      84



above. Other participants in the retention plan also have a financial incentive
to remain with the combined company until the second payout date, one year
following completion of the merger, as this amount will not be payable if the
participant is no longer employed by HP at that time.

   Under the terms of her existing employment agreement, in the event that Ms.
Fiorina's employment is terminated involuntarily other than for cause, death or
disability, or if Ms. Fiorina terminates her employment for good reason
(generally a reduction in Ms. Fiorina's title, responsibilities or
compensation, breach by HP of its obligations under the employment agreement,
or failure to appoint Ms. Fiorina to the HP board of directors), then Ms.
Fiorina will receive her accrued benefits, prorated bonus, a severance amount
of two times her base salary and target variable pay payable over a 24-month
period, a two-year continuation of all welfare plans, full vesting of
restricted stock and restricted stock units, 50% vesting of all unvested stock
options and outplacement services over a 12-month period. It is contemplated
that Ms. Fiorina will enter into a new employment agreement.

   New Employment Agreements Between HP and Certain HP and Compaq Executives

   HP plans to negotiate promptly following the completion of the merger new
employment agreements with Ms. Fiorina and certain executive officers of HP,
including Mr. Joshi, President, Imaging and Printing Systems, Mr. McKinney,
President, Business Customer Organization, Ms. Livermore, President, HP
Services, Mr. Wayman, Executive Vice President, Finance and Administration and
Chief Financial Officer, and Mr. Zitzner, President, Computing Systems; as well
as Mr. Capellas and certain executive officers of Compaq, including Peter
Blackmore, Executive Vice President, Worldwide Sales and Services, Jeff Clarke,
Senior Vice President, Finance and Administration, and Chief Financial Officer,
Michael Winkler, Executive Vice President, Global Business Units, and Shane
Robison, Senior Vice President, Technology and Chief Technology Officer.

   At the time of the execution of the merger agreement, HP expressed the
intention to negotiate with certain HP and Compaq executives employment
agreements to take effect following the closing of the merger, based on terms
for such agreements that were then under discussion but upon which agreement
was not then, or at any later time, reached. Following execution of the merger
agreement, HP and Compaq determined that it would be more appropriate for the
compensation committee of the newly constituted board following completion of
the merger to analyze, review and determine the appropriate structure and size
of compensation packages for executives of the combined company. HP and Compaq
agreed that this process would involve obtaining market information and other
input from outside compensation experts and HP has determined that the
employment terms previously discussed would not serve as a benchmark for any
future terms. It is currently expected that the employment agreements will
include increases to the executives' current salaries to reflect their expanded
responsibilities within the combined company, as well as the potential for a
bonus that may be equal to or greater than the executives' base salaries. HP
also currently expects the employment agreements to provide for the grant of
stock options. It is contemplated that the options will vest based upon
continued service with HP and, in significant part, upon the attainment of
certain performance goals. Such goals may include operational milestones and
increases in HP stock prices following the merger. In addition, HP currently
expects that the employment agreements will contain severance terms that will
provide the officers with payments of severance if, during the term of the
agreement, the executive is terminated without cause, resigns for certain
reasons or terminates employment due to death or disability. These severance
payments may include cash payments, continued employee benefits, additional
payments in connection with any golden parachute excise taxes and the
acceleration of vesting of stock options and other equity awards, but are
expected to be offset by any payments under the retention/severance plan
described above, in the case of HP executives, and below in the case of Compaq
executives.

                                      85



   Interests of Compaq Directors and Executive Officers in the Merger

   Certain members of the management of Compaq and the Compaq board of
directors have interests in the merger that may be different from, or in
addition to, the interests of the other shareowners of Compaq generally. These
interests are summarized below.

   Retention Agreements

   The talent and drive of Compaq's employees is one of the company's most
important assets, and the success of the combined company will be determined in
part by how effectively this resource can be utilized in the new organization.
The period of uncertainty associated with completing the merger and integrating
the companies could, in the absence of a concerted effort to address those
concerns, lead some of Compaq's key employees, including executives, to accept
other employment opportunities. To address this issue, Compaq has developed a
retention program that provides incentives to encourage selected employees to
remain with the company through the completion of the merger and for a
reasonable transition period after the merger. This retention program helps
stabilize workforce turnover in positions critical to completing the merger and
the integration efforts that will begin upon closing. With regard to each
participating executive officer, the human resources committee of the Compaq
board of directors believes that these retention arrangements, by providing for
aggregate payments equal to the severance payments to which the individual
would be eligible under his or her existing severance arrangement (described
below), will minimize any financial incentive for the individual to resign and
claim those severance payments, thereby allowing each of these executives to
remain with the combined company following the merger.

   Compaq's retention program, which is being implemented in phases, provides
cash incentives to employees throughout the company who are critical to ongoing
business efforts, completion of the merger, and post-merger integration.
Retention payments will be made at closing and at the conclusion of a
reasonable retention period of six months to one year thereafter, depending on
the individual's role and anticipated business needs, provided that the
individual remains employed by HP. Payments under the program are contingent
upon completion of the merger, and for many participants, including the seven
participating executive officers, payments under the retention program will be
offset against any severance payments for which the employee becomes eligible
during the year following the completion of the merger. If paid in full and not
taking into account any offset against severance, it is expected that payments
under the program to non-executive officers will total $153.5 million in the
fiscal year in which the merger occurs and $88.5 million in the following
fiscal year. The seven participating executive officers (Messrs. Blackmore,
Winkler, Clarke, Robison, Siekman, and Napier and Ms. Jackson) are eligible for
retention payments totaling three times the sum of their base salary and target
annual bonus (both as in effect upon completion of the merger), payable 50% at
completion of the merger and 50% one year later, provided they remain employed
by HP. The aggregate amount of the retention payments for these seven executive
officers will total approximately $22.4 million, if paid in full and not taking
into account any offset against severance. Mr. Capellas was also eligible to
receive retention bonuses totaling three times the sum of his current base
salary and target annual bonus (a total of $14.4 million) under this program,
but he has declined to accept the right to participate in this program.

   Severance Arrangements

   In 2000, the human resources committee of the Compaq board of directors
approved a new employment agreement for Mr. Capellas and new severance
agreements for the other executive officers of Compaq. These new agreements,
which were developed based on information provided by outside compensation
consultants, were intended to bring key aspects of Compaq's executive
compensation programs into line with competitive market practices. Among other
things, the agreements provide for special severance benefits in the event of a
''qualifying termination'' (which would include, for example, involuntary
termination by the company without cause or resignation by the executive for
certain enumerated ''good reasons,'' such as material diminution in duties,
certain reductions in compensation that are not part of across-the-board cuts,
or ceasing to be an executive officer) following a change in control.

                                      86



   In light of the potential merger, in August of 2001 the human resources
committee revisited these agreements. It was clear that the proposed merger
with HP would constitute a change in control for purposes of the agreements and
there was a concern that many of Compaq's executive officers would qualify for
severance benefits as a result of changes associated with the merger. In order
to aid in retaining these executives, the committee approved the following
amendments to their agreements:

   .   a change in control of Compaq, for purposes of the agreements and for
       purposes of accelerated vesting of any restricted stock previously
       granted to the executives, will occur upon completion of the transaction
       constituting a change in control rather than upon shareowner approval,
       aiding the company in retaining the executives through closing;

   .   the period during which the executive may claim severance under his or
       her agreement following a change in control was extended to one year,
       allowing the company and the executive an adequate period of time to
       evaluate a potential ongoing employment relationship in the new company;
       and

   .   for the participating executives, the retention payments described
       above, which will offset any severance payments to be made under the
       agreements, will be made in two installments, the first installment to
       be paid upon completion of the merger and the second installment to be
       made if the executive remains with the company through the one-year
       retention period following completion of the merger.

   Under these agreements, the executive will be entitled to the following
payments and benefits in the event of a qualifying termination within one year
following completion of the merger:

   .   a lump sum severance payment generally equal to three times the sum of
       base salary and target annual bonus, less any retention payments
       previously made to the executive in connection with the merger; in the
       event that these severance payments are made, the executive will be
       ineligible for any retention payments not yet made (since Mr. Capellas
       has declined to accept the right to participate in the retention
       program, his lump sum severance payment will not be subject to offset
       for retention payments);

   .   a pro-rata target annual bonus for the period in which termination
       occurs;

   .   continued health insurance coverage for two years following termination;

   .   certain financial counseling and outplacement services;

   .   reimbursement of legal fees; and

   .   an additional payment to make the executive whole with respect to any
       golden parachute taxes imposed under the Internal Revenue Code.

   Upon a qualifying termination, the balance of a loan previously made to Mr.
Capellas in 1999 to purchase Compaq stock (remaining principal of approximately
$3.3 million, which would otherwise be forgiven in consideration of continued
service during 2002 and 2003) will be forgiven and Mr. Capellas will be
entitled to a cash payment of $100,000 for the purposes of assisting him with
tax preparation, accounting or legal fees, outplacement services, or other
similar purposes.

   If all of Compaq's executive officers (other than Mr. Capellas) were to
incur a qualifying termination within one year following completion of the
merger, they would receive cash severance payments, in the aggregate, equal to
approximately $11.2 million. This total amount reflects the offset for the
initial installment of the retention program paid to these executives at the
time of the merger and, as noted above, the executives would not be eligible to
receive the second installment under the retention program. If Mr. Capellas
were to incur a qualifying termination of employment within one year following
completion of the merger, he would receive cash severance payments equal to
approximately $14.4 million.

                                      87



   New Employment Agreements between HP and Certain Compaq Executives


   HP plans to negotiate promptly following the completion of the merger
employment agreements with certain executive officers of Compaq, including Mr.
Capellas and the following other executive officers: Peter Blackmore, Executive
Vice President, Worldwide Sales and Services, Jeff Clarke, Senior Vice
President, Finance and Administration, and Chief Financial Officer, Michael
Winkler, Executive Vice President, Global Business Units, and Shane Robison,
Senior Vice President, Technology and Chief Technology Officer. See the section
entitled "Interests of HP Directors and Executive Officers in the Merger--New
Employment Agreements Between HP and Certain HP and Compaq Executives"
beginning on page 85 of this joint proxy statement/prospectus.


   Equity-Based Incentive Plans

   As of January 1, 2002, Compaq's directors and executive officers held
unvested stock options to acquire an aggregate of 5,496,000 shares, with an
average weighted exercise price of $23.40 per share. These options will be
converted upon completion of the merger into options to acquire an aggregate of
approximately 3.5 million HP common shares with a weighted average exercise
price of approximately $37.00 per share. In accordance with the terms of
various equity plans under which they were granted, which are generally
applicable to all holders, options granted prior to September 1, 2001 will
become fully exercisable upon shareowner approval of the merger and, in the
event of a qualifying termination (as defined in the various equity plans under
which they were granted) within one year following the completion of the
merger, the post-termination period of exercisability of outstanding options
generally will be three years from the date of such qualifying termination. The
remainder of these options generally will become fully vested in the event of a
qualifying termination (as defined in the various equity plans under which they
were granted) within one year following the completion of the merger. In
addition, upon completion of the merger, restrictions with respect to an
aggregate of approximately 1.1 million shares of restricted stock currently
held by Compaq's executive officers, as a group, will lapse.

   Under Compaq's Non-Qualified Stock Option Plan for Non-Employee Directors,
all options granted prior to September 1, 2001 will become fully vested upon
shareowner approval of the merger and all options granted on or after September
1, 2001 will become fully vested upon any termination of the director's service
(other than due to death, disability or retirement) within one year following
the completion of the merger.

   Directors Charitable Award Program

   Under Compaq's Directors Charitable Award Program, the rights of two
non-employee directors of Compaq which are not currently vested will become
vested upon completion of the merger. At such time, in complete satisfaction of
Compaq's obligations under the Charitable Award Program, Compaq will make
payments aggregating approximately $12 million on behalf of all participating
directors (and former directors) to the charities previously designated by such
directors.

   Appointment of Directors

   In accordance with the terms of the merger agreement, at and after the time
the merger is completed, HP's board of directors will include five Compaq
directors who are reasonably acceptable to HP, one of whom is expected to be
Mr. Capellas. HP has stated its intent that, at and after the completion of the
merger, each committee of the HP board of directors will include at least one
Compaq director designee and a Compaq director designee will be chairman of at
least one of the audit, compensation, finance and investment or nominating and
governance committees of the HP board of directors.

   Indemnification; Directors' and Officers' Insurance

   HP will, and has agreed to cause the company surviving the merger to, honor
all of the indemnification obligations of Compaq to its directors and officers
that exist immediately prior to completion of the merger,

                                      88



whether pursuant to Compaq's certificate of incorporation, Compaq's bylaws or
an indemnification agreement. For six years after the completion of the merger,
the certificate of incorporation and bylaws of the company surviving the merger
will contain provisions with respect to exculpation and indemnification that
are at least as favorable to the directors and officers who were indemnified by
Compaq immediately prior to completion of the merger as the exculpation and
indemnification provisions that were contained in the restated certificate of
incorporation and bylaws of Compaq in effect at the time the merger agreement
was executed. The certificate of incorporation and bylaws of each of HP and
Compaq generally provide the directors and officers of the respective company
indemnification to the fullest extent permitted by applicable law. However,
unlike the officers and directors of Compaq, the officers and directors of HP
who initiate proceedings must obtain authorization from the HP board of
directors prior to obtaining indemnification or advance payments. For six years
after the completion of the merger, HP also will cause the company surviving
the merger to use all reasonable efforts to maintain the directors' and
officers' liability insurance maintained by Compaq covering those directors and
officers of Compaq who had been covered by such insurance at the time the
merger agreement was executed. The directors' and officers' liability insurance
policy maintaining the coverage of those directors and officers of Compaq will
have terms comparable to those applicable to Compaq's directors and officers on
the date the merger agreement was executed. The company surviving the merger
will not be required to pay, in total, an annual premium for the insurance
described in this paragraph in excess of 150% of the current annual premium
paid by Compaq for its existing insurance coverage prior to the merger.
However, if the annual premiums of such insurance coverage exceed that amount,
the company surviving the merger will use all reasonable efforts to cause to be
maintained the maximum amount of coverage as is available for such 150% of such
annual premium.

The Merger Agreement

   The following summary describes the material provisions of the merger
agreement. The provisions of the merger agreement are complicated and not
easily summarized. This summary may not contain all of the information about
the merger agreement that is important to you. The merger agreement is attached
to this joint proxy statement/prospectus as Annex A and is incorporated by
reference into this joint proxy statement/prospectus, and we encourage you to
read it carefully in its entirety for a more complete understanding of the
merger agreement.

   Structure of the Merger

   The merger agreement provides for the merger of Heloise Merger Corporation,
a newly formed, wholly-owned subsidiary of HP, with and into Compaq. Compaq
will survive the merger as a wholly-owned subsidiary of HP. HP currently
intends to merge Compaq into HP as soon as reasonably practicable following the
merger.

   Completion and Effectiveness of the Merger


   We will complete the merger when all of the conditions to completion of the
merger contained in the merger agreement described in the section entitled
"Conditions to Completion of the Merger" beginning on page 100 of this joint
proxy statement/prospectus are satisfied or waived, including approval of the
issuance of shares of HP common stock in connection with the merger by the
shareowners of HP and approval and adoption of the merger agreement and
approval of the merger by the shareowners of Compaq. The merger will become
effective upon the filing of a certificate of merger with the Secretary of
State of the State of Delaware.


   We are working to complete the merger as quickly as possible. We currently
plan to complete the merger by June 30, 2002. Because completion of the merger
is subject to governmental and regulatory approvals and other conditions,
however, we cannot predict the exact timing.

                                      89



   Conversion of Compaq Common Stock in the Merger


   Upon completion of the merger, each share of Compaq common stock (including,
with respect to each share of Compaq common stock, the associated right
described in the section entitled "Compaq Shareowner Rights Plan" beginning on
page 130 of this joint proxy statement/prospectus) outstanding immediately
prior to the effective time of the merger will be canceled and extinguished and
automatically converted into the right to receive 0.6325 of a share of HP
common stock (including, with respect to each whole share of HP common stock
issued, the associated right described in the section entitled "HP Shareowner
Rights Plan" beginning on page 128 of this joint proxy statement/prospectus)
upon surrender of the certificate representing such share of Compaq common
stock in the manner provided in the merger agreement. Upon completion of the
merger, HP also will assume outstanding options to purchase Compaq common stock
and Compaq SARs as described in the section entitled "Treatment of Compaq Stock
Options and SARs" beginning on page 98 of this joint proxy statement/prospectus.


   The exchange ratio in the merger (i.e., 0.6325 of a share of HP common stock
for each share of Compaq common stock) also will be adjusted to reflect the
effect of any stock split, reverse stock split, stock dividend (including any
dividend or distribution of securities convertible into HP common stock or
Compaq common stock), reorganization, recapitalization, reclassification or
other like change with respect to HP common stock or Compaq common stock having
a record date on or after the date of the merger agreement and prior to
completion of the merger.

   Each share of Compaq common stock held by Compaq or owned by HP or any of
their direct or indirect wholly-owned subsidiaries immediately prior to the
merger will be automatically canceled and extinguished, and none of Compaq, HP
or any of their direct or indirect subsidiaries will receive any securities of
HP or other consideration in exchange for those shares.

   Based on the exchange ratio and the number of shares of Compaq common stock
and options to purchase Compaq common stock outstanding as of the record date,
a total of approximately 1,078,182,486 shares of HP common stock will be issued
in connection with the merger to holders of Compaq common stock and a total of
approximately 320,808,010 shares of HP common stock will be reserved for
issuance upon the exercise of options to purchase Compaq common stock assumed
by HP in connection with the merger. In addition, HP will assume Compaq's stock
plans, under which, as of the record date, approximately 75,752,508 shares of
Compaq common stock, equivalent to 47,913,461 shares of HP common stock as
adjusted to reflect the exchange ratio, are available for future grant.

   Fractional Shares

   HP will not issue any fractional shares of common stock in connection with
the merger. Instead, each holder of Compaq common stock exchanged in connection
with the merger who would otherwise be entitled to receive a fraction of a
share of common stock of HP will receive cash, without interest, in an amount
equal to the fraction multiplied by the average closing price of one share of
HP common stock for the ten most recent trading days that HP common stock has
traded ending on the trading day one day prior to the date the merger is
completed, as reported on the New York Stock Exchange composite transactions
tape.

   Exchange of Compaq Stock Certificates for HP Stock Certificates

   Promptly following completion of the merger, Computershare Trust Company of
New York, the exchange agent for the merger, will mail to each record holder of
Compaq common stock a letter of transmittal and instructions for surrendering
the record holder's stock certificates in exchange for a statement indicating
book-entry ownership of HP common stock or, if requested, a certificate
representing HP common stock. Only those holders of Compaq common stock who
properly surrender their Compaq stock certificates in accordance with the
exchange agent's instructions will receive (1) a statement indicating
book-entry ownership of HP common stock

                                      90



or, if requested, a certificate representing HP common stock, (2) cash in lieu
of any fractional share of HP common stock, and (3) any dividends or other
distributions, if any, to which they are entitled under the terms of the merger
agreement. The surrendered certificates representing Compaq common stock will
be canceled. After the effective time of the merger, each certificate
representing shares of Compaq common stock that has not been surrendered will
represent only the right to receive each of the items enumerated in the
preceding sentence. Following the completion of the merger, Compaq will not
register any transfers of Compaq common stock on its stock transfer books.

   Holders of Compaq common stock should not send in their Compaq stock
certificates until they receive a letter of transmittal from Computershare
Trust Company of New York, the exchange agent for the merger, with instructions
for the surrender of Compaq stock certificates.

   Distributions with Respect to Unexchanged Shares

   Holders of Compaq common stock are not entitled to receive any dividends or
other distributions on HP common stock until the merger is completed. After the
merger is completed, holders of Compaq common stock certificates will be
entitled to dividends and other distributions declared or made after completion
of the merger with respect to the number of whole shares of HP common stock
which they are entitled to receive upon exchange of their Compaq stock
certificates, but they will not be paid any dividends or other distributions on
the HP common stock until they surrender their Compaq stock certificates to the
exchange agent in accordance with the exchange agent instructions.

   Transfers of Ownership and Lost Stock Certificates

   HP will issue only (1) a statement indicating book-entry ownership of HP
common stock or, if requested, an HP stock certificate, (2) cash in lieu of a
fractional share and (3) any dividends or distributions that may be applicable
in a name other than the name in which a surrendered Compaq stock certificate
is registered if the person requesting such exchange presents to the exchange
agent all documents required to show and effect the unrecorded transfer of
ownership and to show that such person paid any applicable stock transfer
taxes. If a Compaq stock certificate is lost, stolen or destroyed, the holder
of such certificate may need to deliver an affidavit or bond prior to receiving
any statement indicating book-entry ownership of HP common stock or HP stock
certificate.

   HP and Compaq Prohibited from Soliciting Other Offers

   Under the terms of the merger agreement, subject to certain exceptions
described below, each of HP and Compaq have agreed that it will not, and each
of its subsidiaries, officers and directors and the officers and directors of
its subsidiaries will not, directly or indirectly:

   .   solicit, initiate, encourage, knowingly facilitate or induce any inquiry
       with respect to, or the making, submission or announcement of, any
       acquisition proposal by a third party of the type described below;

   .   participate or engage in any discussions or negotiations with any third
       party regarding any acquisition proposal of the type described below;

   .   furnish to any person any nonpublic information regarding, or take any
       other action to facilitate any inquiries or the making of any proposal
       that constitutes or may be reasonably be expected to lead to, any
       acquisition proposal of the type described below;

   .   approve, endorse or recommend any acquisition proposal of the type
       described below; or

   .   enter into any letter of intent or similar document or any contract
       agreement or commitment contemplating or otherwise relating to any
       acquisition proposal of the type described below or any transaction
       contemplated by the acquisition proposal.

   In addition, each of HP and Compaq agreed to use all reasonable efforts to
cause its and its subsidiaries' employees, agents and representatives
(including any retained investment banker, attorney or accountant) not to do
any of the foregoing.

                                      95



   An acquisition proposal is any offer or proposal, including a tender or
exchange offer, by a third party or group with respect to HP or Compaq that
would result in any of the following:

   .   the acquisition by any person or group of more than a 10% interest in
       the total outstanding voting securities of the party or any of its
       subsidiaries;

   .   any merger, consolidation, business combination or similar transaction
       involving the party or any of its subsidiaries;

   .   any sale, lease outside the ordinary course of business, exchange,
       transfer, license outside the ordinary course of business, acquisition
       or disposition of more than 10% of the assets of the party (including
       its subsidiaries taken as a whole); or

   .   any liquidation or dissolution of the party.

   Under the merger agreement, each of HP and Compaq agreed to cease, as of
September 4, 2001, all existing activities, discussions or negotiations with
any parties conducted prior to that date with respect to any acquisition
proposal.

   Each of HP and Compaq is obligated to promptly notify the other orally and
in writing upon receipt of any type of acquisition proposal described above or
any request for nonpublic information or inquiry it reasonably believes would
lead to an acquisition proposal. The notice must include the material terms and
conditions of the acquisition proposal, request or inquiry, the identity of the
person or group making the acquisition proposal, request or inquiry and all
related written materials provided in connection with the acquisition proposal,
request or inquiry. Following delivery of the initial notice to the other
party, the party receiving an acquisition proposal, request or inquiry of the
type described above also must provide the other party with all information as
is reasonably necessary to keep the other party informed in all material
respects of the status and details of the acquisition proposal, request or
inquiry. Each of HP and Compaq further agreed to generally provide the other
party with 48 hours' notice of any meeting of its board of directors at which
its board of directors is reasonably expected to consider any acquisition
proposal.

   Notwithstanding the prohibitions contained in the merger agreement with
respect to the type of acquisition proposals described above, if either of HP
or Compaq receives an unsolicited bona fide written acquisition proposal that
its board of directors concludes in good faith, following the receipt of the
advice of its outside legal counsel and its financial advisor, satisfies, or is
reasonably likely to result in an acquisition proposal that satisfies, each of
following criteria that constitute a superior offer:

   .   the acquisition proposal is an unsolicited bona fide written offer to
       the board of directors made by a third party to acquire all or
       substantially all of the company's assets or a majority of its total
       outstanding voting securities, as a result of which the shareowners of
       the company immediately preceding the transaction would hold less than
       50% of the equity interests in the surviving or resulting entity of such
       transaction (or any direct or indirect parent or subsidiary thereof);

   .   the proposed acquisition is on terms that the recipient board of
       directors has in good faith concluded (following receipt of advice of
       its outside legal counsel and its financial advisor) after taking into
       account, among other things, all legal, financial, regulatory and other
       aspects of the offer and the person or group making the offer (1) to be
       more favorable, from a financial point of view, to its shareowners than
       the terms of the merger and (2) is reasonably capable of being completed;

then the party receiving the superior offer may furnish nonpublic information
to, and engage in negotiations with, the third party making the acquisition
proposal, if its board of directors concludes in good faith, following the
receipt of advice of its outside legal counsel, that failure to do so is
reasonably likely to result in a breach of its fiduciary obligations under
applicable law.

   In the event that either of HP or Compaq furnishes nonpublic information to
a third party making an acquisition proposal, it is required to give the other
party advance notice of such action and a copy of the

                                      96



information furnished concurrently with its delivery of such information to the
potential third party acquirer. It also must enter into a confidentiality
agreement with the third party on terms which are at least as restrictive as
the terms contained in the confidentiality agreement entered into between HP
and Compaq. In addition, in the event that a party enters into negotiations
with a third party making an acquisition proposal, it is required to give the
other party written notice of its intention to enter into negotiations with the
third party.

   Obligations of the HP Board of Directors and Compaq Board of Directors with
Respect to its Recommendation and Holding a Meeting of its Shareowners

   The HP board of directors agreed to call, hold and convene a meeting of its
shareowners promptly after the registration statement of which this joint proxy
statement/prospectus forms a part is declared effective by the Securities and
Exchange Commission. The HP board of directors also agreed to recommend the
approval of the issuance of shares of HP common stock in connection with the
merger to its shareowners and to use all reasonable efforts to obtain the
required shareowner approval. The Compaq board of directors agreed to call,
hold and convene a meeting of its shareowners promptly after the registration
statement of which this joint proxy statement/prospectus forms a part is
declared effective by the Securities and Exchange Commission. The Compaq board
of directors also agreed to recommend the approval and adoption of the merger
agreement and approval of the merger to its shareowners and to use all
reasonable efforts to obtain the required shareowner adoption and approvals.
Notwithstanding each of the HP board of directors' and the Compaq board of
directors' obligations described in this paragraph, in response to a third
party acquisition proposal deemed by the board of directors to be a superior
offer, the board of directors of HP or Compaq, as the case may be, may
withhold, withdraw, amend or modify its recommendation to its shareowners as
described in this paragraph and, in the case of a superior offer that is a
tender or exchange offer made directly to its shareowners, may recommend that
its shareowners accept the tender or exchange offer if the following conditions
are met:

   .   a superior offer has been made and has not been withdrawn;

   .   its shareowners' meeting has not occurred;

   .   it has provided the other party with written notice of its receipt of a
       superior offer and has disclosed in the notice the material terms and
       conditions of the superior offer, the identity of the third party or
       group making the offer, and its intent to change its recommendation to
       its shareowners and the manner in which it intends to do so;

   .   it has provided to the other party a copy of all written materials
       delivered to the third party or parties making the superior offer in
       connection with the offer, and it has made available to the other party
       all materials and information it has made available to the third party
       or parties making the superior offer in connection with the offer;

   .   its board of directors has concluded in good faith, after receipt of
       advice of its outside legal counsel, that in light of a superior offer,
       the failure of the board of directors to change its recommendation is
       reasonably likely to result in a breach of its fiduciary obligations to
       its shareowners under applicable law; and


   .   it has not breached in any material respect the handling of third party
       acquisition proposals as described in the section entitled "HP and
       Compaq Prohibited from Soliciting Other Offers" beginning on page 95 of
       this joint proxy statement/prospectus or its obligations to call, hold
       and convene a meeting of its shareowners, and to make the
       recommendations to its shareowners required under to the merger
       agreement, as described in this section.


   Regardless of whether the board of directors of either of HP or Compaq has
received an acquisition proposal or has withheld, withdrawn, amended or
modified its recommendation to its shareowners, in the case of HP, to vote
"for" for the proposal to approve the issuance of shares of HP common stock in
connection with the merger, or, in the case of Compaq, to vote "for" the
proposal to approve and adopt the merger agreement and approve the merger, each
of HP and Compaq is obligated under the terms of the merger agreement to call,
give notice of,

                                      97



convene and hold a special meeting of its shareowners to consider and vote upon
its respective proposal. Neither HP nor Compaq is permitted under the merger
agreement to submit to the vote of its respective shareowners any acquisition
proposal, or propose to do so.

   Treatment of Compaq Stock Options and SARs

   When the merger is completed, HP will assume outstanding options to purchase
shares of Compaq common stock and convert them into options to purchase shares
of HP common stock. HP will convert each assumed Compaq option into an option
to purchase that number of shares of HP common stock equal to the number of
shares of Compaq common stock purchasable pursuant to the Compaq option
immediately prior to the effective time of the merger, multiplied by the
exchange ratio, rounded down to the nearest whole number of shares of HP common
stock. The exercise price per share will be equal to the exercise price per
share of Compaq common stock divided by the exchange ratio, rounded up to the
nearest whole cent. Each assumed option will be subject to all other terms and
conditions set forth in the applicable documents evidencing each Compaq option
immediately prior to the effective time of the merger, including any repurchase
rights or vesting provisions. As of the record date, options for approximately
320,808,010 shares of Compaq common stock were outstanding in the aggregate
under various Compaq stock option plans.

   HP also will assume outstanding Compaq SARs and convert them into SARs
relating to HP common stock. The number of shares to which each SAR relates and
the base price of each SAR will be adjusted in the same manner as described
above with respect to options to purchase Compaq common stock. As of the record
date, Compaq SARs relating to an aggregate of approximately 3,021,902 shares of
Compaq common stock were outstanding under various Compaq equity-based plans.

   HP will file a registration statement on Form S-8 with the Securities and
Exchange Commission, to the extent available, for the shares of HP common stock
issuable with respect to Compaq options and Compaq SARs assumed by HP in
connection with the merger.

   Treatment of Rights under the Compaq Employee Stock Purchase Plan

   Compaq's employee stock purchase plan permits eligible Compaq employees to
purchase Compaq common stock at a discount pursuant to such employees'
participation in the Compaq employee stock purchase plan. Prior to the
effective time of the merger, the Compaq employee stock purchase plan will be
terminated. Any offering period then underway under the Compaq employee stock
purchase plan will be shortened, if necessary, and pro rata adjustments to the
rights of employees in the Compaq employee stock purchase plan will be made to
reflect the shortened offering period. Each shortened offering period will
otherwise be treated as a fully effective and completed offering period for all
purposes under the Compaq employee stock purchase plan.

   Compensation of Compaq Employees

   In the merger agreement, HP has stated its intent that, for a 12-month
period after the merger, HP would use all reasonable efforts to provide
generally to those Compaq employees prior to the merger who become employees of
the combined company after the merger a total compensation (including benefits)
package that, in the aggregate, is generally comparable to the total
compensation (including benefits) package provided to those employees prior to
the date of the merger agreement. HP also agreed to use all reasonable efforts
to give continuing Compaq employees full credit for prior service with Compaq
or its subsidiaries for purposes of (1) eligibility and vesting under any HP
employee benefit plan, (2) benefits levels under any HP vacation or severance
plan and (3) determination of retiree status under any HP equity compensation
plan, for which the employee is otherwise eligible and in which the employee is
offered participation. However, full service credit will not be given where
such crediting would result in a duplication of benefits or otherwise cause HP
or its subsidiaries or any HP plan or related trust to accrue or pay for
benefits that relate to any time prior to the Compaq employee's participation
in the HP plan.

                                      98



   Under the merger agreement, the statements in the preceding paragraph
regarding employee compensation are statements of intent only, and no Compaq
employee or other person or entity, including Compaq, has any rights of
enforcement relating to those statements and no Compaq employee or other person
or entity, including Compaq, is intended to be a contractual beneficiary of the
statements.

   Board of Directors and Management of HP Following the Merger

   The HP board of directors agreed to take all actions necessary such that,
immediately following completion of the merger, the HP board of directors will
include five Compaq directors who are reasonably acceptable to HP, one of whom
is expected to be Mr. Capellas. The HP board of directors agreed to take all
further actions necessary such that immediately following completion of the
merger the HP board of directors will contain no more than two directors who
are employees of HP following the merger.

   In the merger agreement, HP has stated its intent that, immediately
following the merger, each committee of the HP board of directors will include
at least one Compaq designee and a Compaq designee will be chairman of at least
one of the audit, compensation, finance and investment or nominating and
governance committees of the HP board of directors.

   In the merger agreement, HP has stated its intent to negotiate in good faith
with certain persons who are currently senior executives of HP and Compaq who
are expected to become (or continue to be) senior executives of HP following
the merger for such persons to accept the positions and terms of employment
previously discussed between HP and Compaq.


   Under the merger agreement, the statements in the two preceding paragraphs
regarding the composition of the committees of HP board of directors and senior
executives of HP following the merger are statements of intent only, and no
Compaq employee or other person, including Compaq, has any rights of
enforcement relating to those statements and no Compaq employee or other person
or entity, including Compaq, is intended to be a contractual beneficiary of the
statements.


   Regulatory Filings; Antitrust Matters; Reasonable Efforts to Obtain
Regulatory Approvals

   Each of HP, Heloise Merger Corporation and Compaq agreed to coordinate and
cooperate with one another and use all reasonable efforts to comply with, and
refrain from actions that would impede compliance with, applicable laws,
regulations and any other requirements of any governmental entity. HP and
Compaq also agreed to make all filings and submissions required by any
governmental entity in connection with the merger and the other transactions
contemplated by the merger agreement including the following:

   .   those filings or submissions required under the Hart-Scott-Rodino Act,
       the European Community merger regulation and the Competition Act
       (Canada), as well as any other comparable merger notification or control
       laws of any applicable jurisdiction, as agreed by the parties;

   .   any other consents, approvals, orders, authorizations, registrations,
       declarations and filings as may be required under applicable foreign and
       state securities or related laws.

   .   consult with the other with respect to the filings or submissions
       described above, and provide the other party an opportunity to review
       and comment on the filings or submissions and coordinate with the other
       with respect to the filing or submissions;

                                      99



   .   promptly notify the other upon the receipt of any comments or requests
       for amendments or supplements to any filings or submissions made
       pursuant to, or information provided to comply with any applicable laws,
       regulations and any other requirements of any governmental entity; and

   .   provide the other copies of any filing or submission made with any
       governmental entity.


   Subject to the provisions described in the sections entitled "HP and Compaq
Prohibited from Soliciting Other Offers" beginning on page 95 of this joint
proxy statement/prospectus, "Obligations of the HP Board of Directors and
Compaq Board of Directors with Respect to its Recommendation and Holding a
Meeting of its Shareowners" beginning on page 97 of this joint proxy
statement/prospectus and "Limitation on Reasonable Efforts to Obtain Regulatory

to use all reasonable efforts to take, or cause to be taken, all actions, and
to do, or cause to be done, all things necessary, proper or advisable to
complete and make effective the merger and the other transactions contemplated
by the merger agreement in the most expeditious manner practicable.


   Limitation on Reasonable Efforts to Obtain Regulatory Approvals

   Neither HP nor Compaq nor any of their respective subsidiaries or affiliates

       applicable laws, regulations and any other requirements of any

satisfaction or waiver of each of the following conditions before completion of
the merger:

       and its

                                      100



       subsidiaries on a combined basis with Compaq and its subsidiaries, if

       asserted by any governmental authority challenging or seeking to
       restrain or prohibit the completion of the merger or any of the other
       transactions contemplated by the merger agreement, the effect of which
       would be an order making the merger illegal or otherwise prohibiting
       completion of the merger (which illegality or prohibition would have a
       material impact on HP and its subsidiaries on a combined basis with
       Compaq and its subsidiaries, if the merger were completed
       notwithstanding such order);


   .   there is no pending or overtly threatened suit, action or proceeding

   In addition, individually, the respective obligations of HP and Heloise
Merger Corporation on the one hand, and Compaq on the other, to effect the
merger and the other transactions contemplated by the merger agreement are
subject to the satisfaction or waiver of the following additional conditions:

   .   the representations and warranties of the other party will have been
       true and correct on September 4, 2001 and are true and correct as of the
       date the merger is to be completed as if made at and as of that time,
       except:

       -  to the extent the representations and warranties of the other party
          address matters only as of a particular date, they must be true and
          correct as of that date; and

       -  if any of these representations and warranties are not true and
          correct but the effect in each case, or in the aggregate, of the
          inaccuracies of these representations and breaches of these
          warranties, is not and does not have a material adverse effect, as
          defined below, on the other party, then this condition will be deemed
          satisfied;

   .   the other party will have performed or complied in all material respects
       with all of its agreements and covenants required by the merger
       agreement to be performed or complied with by it before completion of

                                      101



   Definition of Material Adverse Effect

   Under the terms of the merger agreement, a material adverse effect on either
HP or Compaq is defined to mean any change, event, violation, inaccuracy,
circumstance or effect, individually or when taken together, that is or is
reasonably likely to (a) be materially adverse to the business, assets
(including intangible assets), capitalization, financial condition or results
of operations of the company taken as a whole with its subsidiaries or (b)
materially impede the authority of the company, or, in any case, HP, to
complete the transactions contemplated by the merger agreement. However, under
the terms of the merger agreement, with respect to clause (a), none of the
following, individually or in combination, will be deemed to constitute, and
none of the following will be taken into account in determining, whether there
has been or will be, a material adverse effect on HP or Compaq, as the case may
be:

   .   any change, event, violation, inaccuracy, circumstance or effect
       resulting from compliance with the terms and conditions of the merger
       agreement;

   .   any change, event, violation, inaccuracy, circumstance or effect
       resulting from the announcement or pendency of the merger, provided that
       this exception does not apply to the use of the term material adverse
       effect as used in:

       -  the condition to the obligation of Compaq to complete the merger that
          HP's representations and warranties with respect to (1) authority,
          (2) the absence of conflicts with applicable legal requirements,
          organizational documents and material contracts, (3) governmental
          approvals, and (4) material contracts, be true and correct as of
          September 4, 2001 and as of the date the merger is completed except
          as would not constitute a material adverse effect; and

       -  the condition to the obligations of HP and Heloise Merger Corporation
          to complete the merger that Compaq's representations and warranties
          with respect to (1) authority, (2) the absence of conflicts with
          applicable legal requirements, organizational documents and material
          contracts, (3) governmental approvals, (4) material contracts and (5)
          impairment of the business or material intellectual property of HP or
          its subsidiaries by virtue of the merger, be true and correct as of
          September 4, 2001 and as of the date the merger is completed except
          as would not constitute a material adverse effect;

   .   any change in the stock price or trading volume, in and of itself, of HP
       or Compaq, as the case may be;

   .   any failure by HP or Compaq, as the case may be, to meet published
       revenue or earnings projections, in and of itself;

   .   any change, event, violation, inaccuracy, circumstance or effect that
       results from changes affecting any of the industries in which such
       entity operates generally or the United States economy generally (which
       changes in each case do not disproportionately affect HP or Compaq, as
       the case may be, in any material respect); or

   .   any shareowner class action litigation arising from allegations of a
       breach of fiduciary duty relating to the merger agreement.

   As a result, any of the foregoing, alone or in combination, may occur with
respect to HP or Compaq without:

   .   giving the other party the right to prevent the completion of the merger
       based on the failure to satisfy the condition to closing that no
       material adverse effect has occurred on it since September 4, 2001 and
       be continuing, as described above; or

   .   giving the other party the right to terminate the agreement based on a
       material adverse effect on it since September 4, 2001, as described
       below;

unless any of the foregoing, alone, in combination or in combination with other
events, is or is reasonably likely to impede materially the authority of it, or
in any case HP, to complete the transactions contemplated in combinations by
the merger agreement.

                                      102



   Termination of the Merger Agreement

   The merger agreement may be terminated in accordance with its terms at any
time prior to completion of the merger, whether before or after the approval
and adoption of the merger agreement and approval of the merger by Compaq
shareowners or the approval of the issuance of shares of HP common stock to
Compaq shareowners by HP shareowners in connection with the merger:

   .   by mutual written consent of HP and Compaq;

   .   by HP or Compaq if the merger is not completed by May 31, 2002 (which
       will be extended to August 30, 2002 if the merger has not been completed
       as a result of a failure to obtain required antitrust approvals or
       existence of governmental regulation or order making the completion of
       the merger illegal or otherwise prohibited), except that this right to
       terminate the merger agreement is not available to any party whose
       action or failure to act has been a principal cause of or resulted in
       the failure of the merger to occur on or before that date, and the
       action or failure to act constitutes a breach of the merger agreement;

   .   by HP or Compaq, if there is any order of a court or other action or
       inaction of any governmental authority having the effect of permanently
       restraining, enjoining or prohibiting the completion of the merger which
       is final and nonappealable;

   .   by HP or Compaq if the issuance of shares of HP common stock to Compaq
       shareowners in connection with the merger fails to receive the requisite
       affirmative vote by the shareowners of HP at a meeting of HP shareowners
       or at any adjournment of that meeting, except that the right to
       terminate the merger agreement is not available to HP where the failure
       to obtain HP shareowner approval was caused by HP's action or failure to
       act and the action or failure to act constitutes a breach by HP of the
       merger agreement;

   .   by HP or Compaq if the merger agreement and the merger fails to receive
       the requisite affirmative vote for adoption and approval at a meeting of
       Compaq shareowners or at any adjournment of that meeting, except that
       this right to terminate the merger agreement is not available to Compaq
       where the failure to obtain Compaq shareowner approval was caused by
       Compaq's action or failure to act and the action or failure to act
       constitutes a breach by Compaq of the merger agreement;

   .   by HP, at any time prior to the adoption and approval of the merger
       agreement and the merger by the required vote of Compaq shareowners, if
       any of the following triggering events occur with respect to Compaq:


       -  its board of directors withdraws, amends or modifies, in a manner
          adverse to the other party, the recommendation of its board of
          directors described in the section entitled "Obligations of the HP
          Board of Directors and Compaq Board of Directors with Respect to its
          Recommendation and Holding a Meeting of its Shareowners" beginning on
          page 97 of this joint proxy statement/prospectus;


       -  it fails to include in this joint proxy statement/prospectus the
          recommendation of its board of directors;

       -  its board of directors fails to reaffirm (publicly, if the other
          party requests) its recommendation within ten calendar days after
          being requested by the other party to reaffirm such recommendation;


       -  its board of directors approves or recommends any acquisition
          proposal of the type described in the section entitled "HP and Compaq
          Prohibited from Soliciting Other Offers" beginning on page 95 of this
          joint proxy statement/prospectus; or


       -  a tender or exchange offer relating to its securities is initiated by
          a third party and it does not send to its securityholders, pursuant
          to Rule 14e-2 promulgated under the Securities and Exchange Act of
          1934 within ten business days after the tender or exchange offer is
          first published, sent or given, a statement disclosing that its board
          of directors recommends rejection of the tender or exchange offer;

                                      103



   .   by Compaq, at any time prior to the approval of the issuance of shares
       of HP common stock to Compaq shareowners in connection with the merger
       by the required vote of HP shareowners, if any of the triggering events
       described above with respect to Compaq occurs with respect to HP;

   .   by Compaq upon a breach of any representation, warranty, covenant or
       agreement on the part of HP in the merger agreement or if any
       representation or warranty of HP has become untrue so that the condition
       to completion of the merger regarding HP's representations and
       warranties or covenants would not be met. However, if the breach or
       inaccuracy is curable by HP through the exercise of reasonable efforts,
       then Compaq may not terminate the merger agreement for 60 days after
       delivery of written notice from Compaq to HP of the breach. If the
       breach is cured during those 60 days, or if Compaq is otherwise in
       material breach of the merger agreement, Compaq may not exercise this
       termination right;

   .   by HP upon a breach of any representation, warranty, covenant or
       agreement on the part of Compaq in the merger agreement or if any
       representation or warranty of Compaq has become untrue so that the
       condition to completion of the merger regarding Compaq's representations
       and warranties or covenants would not be met. However, if the breach or
       inaccuracy is curable by Compaq through the exercise of reasonable
       efforts, then HP may not terminate the merger agreement for 60 days
       after delivery of written notice from HP to Compaq of the breach. If the
       breach is cured during those 60 days, or if HP is otherwise in material
       breach of the merger agreement, HP may not exercise this termination
       right;

   .   by HP, if there is a material adverse effect on Compaq since September
       4, 2001; or

   .   by Compaq, if there is a material adverse effect on HP since September
       4, 2001.

   Payment of Termination Fee


   Under the terms of the merger agreement, each of HP and Compaq have agreed
to pay to the other a termination fee of $675 million within two business days

terminated by the other party because of the occurrence of a triggering event
in relation to it as described in the section entitled "Termination of the
Merger Agreement" beginning on page 103 of this joint proxy
statement/prospectus.


   Under the terms of the merger agreement, HP must pay a termination fee of
$675 million to Compaq if all of the following conditions are met:


   .   between September 4, 2001 and the termination of the merger agreement
       there has been public disclosure of an acquisition proposal by a third
       party with respect to HP of the type described in the section entitled
       "HP and Compaq Prohibited from Soliciting Other Offers" beginning on
       page 95 of this joint proxy statement/prospectus; and


   .   the merger agreement has been terminated on either of the following
       bases:

       -  the merger has not been completed by May 31, 2002 (or August 30, 2002
          if the merger is not completed as a result of a failure to obtain
          required antitrust approvals or the existence of a governmental
          regulation or order having the effect of making the completion of the
          merger illegal or otherwise prohibited); or

          stock in connection with the merger at a meeting of HP shareowners or
          an adjournment of that meeting; and

          enters into an agreement contemplating the acquisition of it in any
          of the manners described below and, within 24 months following the
          termination of the merger agreement, an acquisition of the type
          described below is completed.

                                      104



   The termination fee must be paid within two days following the acquisition
of HP.

   In addition, Compaq must pay a termination fee of $675 million to HP if all
of the following conditions are met:


   .   between September 4, 2001 and the termination of the merger agreement
       there has been public disclosure of an acquisition proposal by a third
       party with respect to Compaq of the type described in the section
       entitled "HP and Compaq Prohibited from Soliciting Other Offers"
       beginning on page 95 of this joint proxy statement/prospectus; and


   .   the merger agreement has been terminated on either of the following
       bases:

       -  the merger has not been completed by May 31, 2002 (or August 30, 2002
          if the merger is not completed as a result of a failure to obtain
          required antitrust approvals or the existence of a governmental
          regulation or order having the effect of making the completion of the
          merger illegal or otherwise prohibited); or

       -  Compaq shareowners failed to adopt and approve the merger agreement
          and to approve the merger at a meeting of Compaq shareowners or an
          adjournment of that meeting; and

   .   either of the following has occurred:

       -  within 12 months following termination of the merger agreement,
          Compaq is the subject of an acquisition of the type described below;
          or

       -  within 12 months following termination of the merger agreement Compaq
          enters into an agreement contemplating the acquisition of it in any
          of the manners described below and, within 24 months following the
          termination of the merger agreement, an acquisition of the type
          described below is completed.

   The termination fee must be paid within two days following the acquisition
of Compaq.

   Under the terms of the merger agreement, an acquisition of either HP or
Compaq, as applicable, for the purposes of these termination provisions, is any
of the following:

   .   a merger, consolidation, business combination, recapitalization,
       liquidation, dissolution or similar transaction involving it, pursuant
       to which its shareowners immediately preceding such transaction hold
       less than 60% of the aggregate equity interests in the surviving or
       resulting entity, or direct parent, of such transaction;

   .   a sale or other disposition by the party of assets representing in
       excess of 40% of the aggregate fair market value of its business,
       immediately prior to such sale; or

   .   the acquisition by any person or group, including by way of a tender
       offer or an exchange offer or issuance by it, directly or indirectly, of
       beneficial ownership or a right to acquire beneficial ownership of
       shares representing in excess of 40% of the voting power of the then
       outstanding shares of its capital stock.

   Payment of the termination fee is not in lieu of damages incurred in the
event of breach of the merger agreement. If the party entitled to payment of
the termination fee has to make a claim against the other party and such claim
results in a judgment against the other party, the party required to pay the
termination fee will also have to pay the other party's reasonable costs and
expenses in connection with the suit together with interest on the unpaid
termination fee.

   Extension, Waiver and Amendment of the Merger Agreement

   HP and Compaq may amend the merger agreement before completion of the merger
by mutual written consent.

                                      105



   Either HP or Compaq may extend the other's time for the performance of any
of the obligations or other acts under the merger agreement, waive any
inaccuracies in the other's representations and warranties and waive compliance
by the other with any of the agreements or conditions contained in the merger
agreement.

United States Federal Income Tax Consequences of the Merger

   The following summary discusses the material United States federal income
tax consequences of the merger to Compaq shareowners. The following discussion
is based on existing provisions of the Internal Revenue Code, existing treasury
regulations and current administrative rulings and court decisions, all of
which are subject to change, possibly with retroactive effect, and to differing
interpretations.

   We do not discuss all United States federal income tax considerations that
may be relevant to a particular shareowner in light of his or her personal
circumstances or to shareowners subject to special treatment under the federal
income tax laws, including:

    .  dealers in securities or foreign currencies;

    .  shareowners who are subject to the alternative minimum tax provisions of
       the Internal Revenue Code;

    .  tax-exempt organizations;

    .  non-United States persons or entities;

    .  financial institutions or insurance companies;

    .  shareowners who acquired Compaq common stock in connection with stock
       option or stock purchase plans or in other compensatory transactions; or

    .  shareowners who hold Compaq common stock as part of an integrated
       investment, including a "straddle," comprised of shares of Compaq common
       stock and one or more other positions.

   In addition, we do not discuss the tax consequences of the merger under
foreign, state or local tax law. This discussion assumes that Compaq
shareowners hold their shares of Compaq common stock as capital assets within
the meaning of Section 1221 of the Internal Revenue Code (generally, as
property held as an investment).

   Accordingly, we urge you to consult your tax advisors as to the specific tax
consequences to you of the merger, including any applicable federal, state,
local and foreign tax consequences.

   Based on factual representations contained in letters provided by HP and
Compaq, and on certain customary factual assumptions, all of which must
continue to be true and accurate as of the effective time of the merger, each
of Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel to HP,
and Skadden, Arps, Slate, Meagher & Flom LLP, counsel to Compaq, has delivered
its opinion (attached as exhibits 8.1 and 8.2, respectively, to the
registration statement on Form S-4, of which this joint proxy
statement/prospectus forms a part) that the merger will qualify as a
"reorganization" for United States federal income tax purposes within the
meaning of Section 368(a) of the Internal Revenue Code and that the following
material United States federal income tax consequences will result from such
qualification:

    .  Compaq shareowners will not recognize any gain or loss upon the receipt
       of HP common stock in exchange for Compaq common stock in connection
       with the merger, except for cash received instead of a fractional share
       of HP common stock;

   .   the aggregate tax basis of the HP common stock received by a Compaq
       shareowner in connection with the merger, including any fractional share
       of HP common stock not actually received, will be equal to the aggregate
       tax basis of the Compaq common stock surrendered in exchange for HP
       common stock;

   .   the holding period of the HP common stock received by a Compaq
       shareowner in connection with the merger will include the holding period
       of the Compaq common stock surrendered in connection with the merger;

                                      106



   .   cash payments received by a Compaq shareowner for a fractional share of
       HP common stock will be treated as if such fractional share had been
       issued in connection with the merger and then redeemed by HP, and Compaq
       shareowners will recognize capital gain or loss with respect to such
       cash payment, measured by the difference, if any, between the amount of
       cash received and the tax basis in such fractional share; and

   .   HP, Heloise Merger Corporation and Compaq will not recognize gain or
       loss as a result of the merger.

   The completion of the merger is conditioned upon the delivery of an opinion
by each of Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel
to HP, and Skadden, Arps, Slate, Meagher & Flom LLP, counsel to Compaq, that
the merger will constitute a reorganization for United States federal income
tax purposes within the meaning of Section 368(a) of the Internal Revenue Code.
These opinions will be based on updated representation letters to be provided
by HP and Compaq at the time of the completion of the merger, and on customary
factual assumptions. Although the merger agreement allows HP and Compaq to
waive this condition to the completion of the merger, neither HP nor Compaq
currently anticipates doing so. If either HP or Compaq does waive this
condition, shareowners of HP and Compaq will be informed of this decision and
asked to vote in connection with the merger, taking this waiver into
consideration.

   Neither HP nor Compaq will request a ruling from the Internal Revenue
Service regarding the tax consequences of the merger to Compaq shareowners. The
tax opinions do not bind the Internal Revenue Service and do not prevent the
Internal Revenue Service from successfully asserting a contrary opinion. In
addition, if any of the representations or assumptions upon which the opinions
are based are inconsistent with the actual facts, the tax consequences of the
merger could be adversely affected.

Accounting Treatment of the Merger

   In accordance with United States generally accepted accounting principles,
HP will account for the merger using the purchase method of accounting. Under
this method of accounting, HP will record the market value (based on an average
of the closing prices of HP common stock for a range of trading days from two
days before and after September 3, 2001, the announcement date) of its common
stock issued in connection with the merger, the fair value of the options to
purchase shares of Compaq common stock assumed in connection with the merger
and the amount of direct transaction costs associated with the merger as the
estimated purchase price of acquiring Compaq. HP will allocate the estimated
purchase price to the net tangible and amortizable intangible assets acquired
(including developed and core technology and patents, customer contracts and
lists, and distribution agreements), intangible assets with indefinite lives
and in-process research and development, based on their respective fair values
at the date of the completion of the merger. Any excess of the estimated
purchase price over those fair values will be accounted for as goodwill.

   Amortizable intangible assets, currently estimated at $4.1 billion, will
generally be amortized over useful lives ranging from two to ten years,
resulting in an estimated accounting charge for amortization attributable to
these items of approximately $600 million on an annual basis. In-process
research and development, which is currently estimated at $1 billion, will be
expensed during the fiscal quarter in which the merger is completed. In
accordance with the Statement of Financial Accounting Standards No. 142,
"Goodwill and Other Intangible Assets," intangible assets with indefinite
lives, and goodwill resulting from a business combination completed subsequent
to June 30, 2001, will not be amortized but instead will be tested for
impairment at least annually (more frequently if certain indicators are
present). The amount of the estimated purchase price allocated to goodwill and
intangible assets with indefinite lives, which is based on certain assumptions,
is estimated to be approximately $11.6 billion. If HP management should change
the assumptions used in the allocation of the purchase price, amounts
preliminarily allocated to intangible assets with indefinite lives may
significantly decrease or be eliminated, and amounts allocated to intangible
assets with definite lives may increase significantly, which could result in a
material increase in amortization of intangible assets.

                                      107



   In the event that the management of the combined company determines that the
value of goodwill or intangible assets with indefinite lives has become
impaired, the combined company will incur an accounting charge for the amount
of impairment during the fiscal quarter in which the determination is made. In
addition, in the event that the management of the combined company determines
that the useful life of any intangible assets with indefinite lives has become
definite, the intangible asset will be amortized over its remaining useful
life, and the combined company will incur an accounting charge related to such
amortization during each fiscal quarter of the intangible asset's remaining
useful life. The amounts listed in the above paragraph are only preliminary
estimates, however, actual amounts may differ from these estimates.

Directors and Executive Officers of HP Following the Merger

   HP currently intends to make the following changes to the HP board of
directors following the completion of the merger:

    .  the HP board of directors will include five directors from Compaq who
       are reasonably acceptable to HP, including Mr. Capellas; and

    .  the HP board of directors will contain no more than two directors who
       are employees of HP.

   In addition, following the completion of the merger, HP intends to review
the composition of the HP board of directors and its committees. Specifically,
HP expects that:

    .  each committee of the HP board of directors will include at least one
       Compaq designee;

    .  Ms. Fiorina will step down from the nominating and governance committee
       to allow for an additional outside director to join that committee; and

    .  a Compaq designee will become the chairman of at least one of the audit,
       compensation, finance and investment or nominating and governance
       committees of the HP board of directors.

   In addition, HP plans to negotiate promptly following completion of the
merger with certain persons who are current senior executives of HP and Compaq
and who are expected to become, or continue to be, senior executives of HP
following the merger.


Effect of the Merger on Compaq Stock Plans

   Under Compaq's various equity plans for its employees, stock options and
stock appreciation rights (SARs) granted prior to September 1, 2001 will become
fully vested upon Compaq shareowner approval of the merger in accordance with
the amended terms of Compaq's equity-based plans. Stock options and SARs
granted under the equity-based plans on or after September 1, 2001 will become
fully vested upon any "qualifying termination" (as defined in Compaq's
equity-based plans) of employment within one year following the completion of
the merger, in accordance with the amended terms of Compaq's equity-based
plans. Certain restrictions on grants of restricted stock issued under the
equity-based plans will lapse upon completion of the merger.

   Generally under Compaq's equity-based plans as amended, upon a qualifying
termination within one year of the merger, the participant will have the right
to exercise his or her stock option or SAR until the earlier of:

   .   the third anniversary of the participant's qualifying termination of
       employment (in the case of awards granted prior to September 1, 2001),
       or the first anniversary of the participant's termination of employment
       (in the case of awards granted on or after September 1, 2001); and

   .   the expiration of the term of the stock option or SAR.

                                      108



Assumption of Compaq Stock Plans

   Upon completion of the merger, HP intends to assume Compaq's 2001 Stock
Option Plan, 1998 Stock Option Plan, 1995 Equity Incentive Plan and 1989 Equity
Incentive Plan. As of the record date, 75,752,508 shares of Compaq Common
Stock, equivalent to 47,913,461 shares of HP common stock as adjusted to
reflect the exchange ratio in the merger, remained available for future grants
under these plans. HP intends to file a registration statement on Form S-8 with
the Securities and Exchange Commission following the completion of the merger
with respect to the shares available in connection with future grants under
these assumed option plans.

Regulatory Filings and Approvals Required to Complete the Merger


   The merger is subject to review by the United States Federal Trade
Commission under the Hart-Scott-Rodino Improvements Act of 1976, and was
subject to review by the European Commission under Council Regulation No.
4064/89 of the European Community and by the Canadian Competition Bureau under
the Competition Act (Canada). Under each of these statutes, HP and Compaq were
required to make pre-merger notification filings and, in the case of the
Hart-Scott-Rodino review, HP and Compaq are awaiting the expiration or early
termination of statutory waiting periods prior to completing the merger. By
September 25, 2001, each of HP and Compaq had completed its initial
Hart-Scott-Rodino filing. On October 25, 2001, each of HP and Compaq received a
request for additional information and other documentary material from the
Federal Trade Commission under the Hart-Scott-Rodino Act in connection with the
merger. This request effectively extends the waiting period for the merger
under the Hart-Scott-Rodino Act until 30 days after both parties substantially
comply with the request for additional information. In practice, complying with
a request for additional information or material under the Hart-Scott-Rodino
Act can take a significant amount of time. HP and Compaq responded to the
request for additional information and continue to cooperate with the FTC in
its investigation. In addition, HP formally notified the European Commission of
the merger by Form CO on December 20, 2001. The merger may also be subject to
review by the governmental authorities of various other jurisdictions under the
antitrust laws of those jurisdictions. On January 31, 2002, the European
Commission issued a formal decision clearing the merger on the basis that it
does not create or strengthen a dominant position as a result of which
effective competition would be significantly impeded in the European Economic
Area (as defined by European Community regulations) or in a substantial part of
it. On December 20, 2001, the Canadian Competition Bureau completed its review
of the proposed merger and found no issues of competitive concern. Other than
the European Commission and the Canadian Competition Bureau, HP and Compaq have
not yet obtained any of the governmental or regulatory approvals required to
complete the merger.


   There can be no assurance that the governmental reviewing authorities will
permit the applicable statutory waiting periods to expire, terminate the
applicable statutory waiting periods or clear the merger at all or without
restrictions or conditions that would have a materially adverse effect on the
combined company if the merger is completed. These restrictions and conditions
could include a complete or partial license, divestiture, spin-off or the
holding separate of assets or businesses. Under the terms of the merger
agreement, neither HP nor Compaq is required to comply with any restriction or
condition that would be reasonably likely to materially adversely impact the
benefits expected to be derived by HP and its subsidiaries, on a combined basis
with Compaq and its subsidiaries, as a result of the merger or would be
reasonably likely to materially adversely affect HP and its subsidiaries, on a
combined basis with Compaq and its subsidiaries. Either HP or Compaq may refuse
to complete the merger if any such restrictions or conditions are required by
governmental authorities as a condition to approving the merger. No additional
shareowner approval is expected to be required for any decision by HP or
Compaq, after the special meeting of HP's shareowners and the special meeting
of Compaq's shareowners, to agree to any terms and conditions necessary to
resolve any regulatory objections to the merger.

   In addition, during or after the statutory waiting periods and clearance of
the merger, and even after completion of the merger, either the Antitrust
Division of the United States Department of Justice, the Federal Trade
Commission, the European Commission or other governmental authorities could
challenge or seek to block the merger under the antitrust laws, as it deems
necessary or desirable in the public interest. Other competition

                                      109



agencies with jurisdiction over the merger could also initiate action to
challenge or block the merger. In addition, in some jurisdictions, a
competitor, customer or other third party could initiate a private action under
the antitrust laws challenging or seeking to enjoin the merger, before or after
it is completed. HP and Compaq cannot be sure that a challenge to the merger
will not be made or that, if a challenge is made, HP and Compaq will prevail.

Legal Proceedings Regarding the Merger

   On or about December 11, 2001, a putative class action lawsuit was filed in
the Superior Court of the State of California, County of Santa Clara, against
various officers and directors of HP alleging that the defendants breached
their fiduciary duties to HP shareowners by, among other things, failing to
conduct reasonable due diligence into the propriety of the merger and by filing
with the Securities and Exchange Commission a false and misleading registration
statement on Form S-4 and preliminary joint proxy statement/prospectus forming
a part thereof in connection with the merger. The case, which is encaptioned
Carl S. Bickel, On Behalf of Himself and All Others Similarly Situated v.
Carleton S. Fiorina, et al., Case No. CV-01-4983-CW, seeks declaratory,
injunctive and other relief permitted by law and equity. Defendants removed the
case to the United States District Court for the Northern District of
California on or about December 19, 2001 and filed a motion to dismiss the case
on January 7, 2002. On January 17, 2002, plaintiff filed a motion to remand the
case back to state court. A hearing on plaintiff's motion is currently
scheduled for March 15, 2002. A hearing on defendant's motion to dismiss is
currently scheduled for March 15, 2002. HP believes that the lawsuit is without
merit and intends to vigorously defend the case.

Listing of Shares of HP Common Stock Issued in the Merger on the New York Stock
Exchange and the Pacific Exchange

   HP will use all reasonable efforts to cause the shares of HP common stock
issued in connection with the merger to be authorized for listing on the New
York Stock Exchange and the Pacific Exchange before the completion of the
merger, subject to official notice of issuance.

Delisting and Deregistration of Compaq Common Stock After the Merger

   When the merger is completed, Compaq common stock will be delisted from the
New York Stock Exchange and deregistered under the Securities Exchange Act of
1934.

Restrictions on Sales of Shares of HP Common Stock Received in the Merger

   The shares of HP common stock to be issued in connection with the merger
will be registered under the Securities Act of 1933 and will be freely
transferable, except for shares of HP common stock issued to any person who is
deemed to be an "affiliate" of Compaq prior to the merger. Persons who may be
deemed to be "affiliates" of Compaq prior to the merger include individuals or
entities that control, are controlled by, or are under common control of Compaq
prior to the merger, and may include officers and directors, as well as
principal shareowners of Compaq prior to the merger. Affiliates of Compaq will
be notified separately of their affiliate status.

   Persons who may be deemed to be affiliates of Compaq prior to the merger may
not sell any of the shares of HP common stock received by them in connection
with the merger except pursuant to:

   .   an effective registration statement under the Securities Act of 1933
       covering the resale of those shares;

   .   an exemption under paragraph (d) of Rule 145 under the Securities Act of
       1933; or

   .   any other applicable exemption under the Securities Act of 1933.

                                      110



   HP's registration statement on Form S-4, of which this joint proxy
statement/prospectus forms a part, does not cover the resale of shares of HP
common stock to be received in connection with the merger by persons who may be
deemed to be affiliates of Compaq prior to the merger.

No Appraisal Rights

   Neither HP shareowners nor Compaq shareowners are entitled to dissenters'
rights of appraisal for their shares under the General Corporation Law of the
State of Delaware in connection with the merger.

                                      111



                       BUSINESS OF THE COMBINED COMPANY

Overview of Business Structure


   Following completion of the merger, the combined company will operate in
over 160 countries and expects to have approximately 145,000 employees after
expected headcount reductions through attrition and targeted job reductions. As
of October 31, 2001, unaudited pro forma combined consolidated total assets of
HP and Compaq were approximately $69.2 billion. In addition, for the year ended
October 31, 2001, unaudited pro forma combined consolidated total net revenue
for HP and Compaq was $81.7 billion and earnings from operations were
$1.2 billion. These amounts are not intended to represent or be indicative of
the amounts that would have been reported had the merger been completed as of
the dates presented, and should not be taken as representative of the future
consolidated results of operations or financial condition of HP. See the
section entitled "Unaudited Pro Forma Condensed Combined Consolidated Financial
Statements" beginning on page 114 of this joint proxy statement/prospectus.


   As soon as practicable following the merger, HP intends to merge Compaq into
HP. The combined company will retain its headquarters in Palo Alto, California
and will retain a significant presence in Houston, Texas, which will be a key
strategic center of engineering excellence and product development for the
combined company.

   HP and Compaq plan to integrate their businesses and product lines and
organize the combined company's business into four major groups:

    .  Enterprise Systems;

    .  Services;

    .  Imaging and Printing Systems; and

    .  Personal Systems.

   In addition to these primary business groups, the combined company will
include several corporate level organizations. Among these will be HP Labs,
which will include part of Compaq's research and development function, an
organization focused on corporate philanthropy and community responsibility and
a corporate operations organization focused on areas of cross-company
opportunity, including procurement. We currently intend that the combined
company will use the HP brand for existing HP branded products and new products
that will be introduced after the completion of the merger, while retaining the
Compaq brand and Compaq sub-brands for selected enterprise, commercial and
consumer product lines.

   Enterprise Systems

   The Enterprise Systems group will be led by Mr. Blackmore, currently
Compaq's Executive Vice President, Worldwide Sales and Services, and will
include servers, storage and software. It will provide a full line of computing
systems from high-volume industry standard servers to high-end, fault-tolerant
systems; a wide range of storage solutions from mid-range and high-end array
systems, to storage area networks and storage area management software; and
industry leading offerings in management software, integrated services
management and next generation operating environments.

   Services

   The Services group will be led by Ms. Livermore, currently President of HP
Services, and will provide support, consulting and outsourcing to help design,
build, and manage and support the Enterprise Systems group. The combined
services organization is expected to include 65,000 professionals around the
world. The business offerings of the Services group will include ongoing
support and maintenance, in addition to proactive services like
mission-critical support and networking services, IT consulting and system
integration services, and comprehensive and selective outsourcing.

                                      112



   Imaging and Printing Systems

   The Imaging and Printing group will be led by Mr. Joshi, currently HP's
President of Imaging and Printing Systems. The offerings of the Imaging and
Printing group will continue to include HP LaserJet and Inkjet printer hardware
(both monochrome and color), multi-function laser devices, wide- and
large-format Inkjet printers, printing supplies, scanners, digital photography
products, personal color copiers, faxes and all-in-one products that combine
multiple functions like scanning, copying and printing in one device. HP's
investment in, and pending acquisition of, Indigo, N.V., a leading provider of
high performance digital printing systems used in the production of on-demand,
short-run color digitally-printed products, is designed to enhance HP's
strategy in the evolving commercial printing market. Indigo is expected to add
a third high-speed color print technology to HP's highly successful Inkjet and
LaserJet technologies.

   Personal Systems

   The Personal Systems group will be led by Mr. Zitzner, currently HP's
President of Computing Systems, and will include business and consumer desktop
and mobile personal computers, workstations, handheld computing devices, new
types of Internet-access devices, personal storage devices, and digital music
and entertainment devices. The Personal Systems group will focus on serving
customers through multiple channels including strong distributor, reseller, and
retail channel efforts, in addition to directly serving customers through the
Internet and by telephone.

Integration Office

   HP recognizes the challenge inherent in integrating enterprises of the size
and complexity of HP and Compaq. HP also recognizes that a swift and successful
integration of the two companies is crucial to capturing the potential value of
the merger. Accordingly, HP has established an integration office that will
report directly to Ms. Fiorina. This office will be run jointly by Mr. McKinney
and Mr. Clarke, each a key executive officer at HP and Compaq, respectively.
Mr. McKinney currently serves as the President of HP's Business Customer
Organization and provides a proven record as a line manager and deep expertise
in the HP organization. Mr. Clarke currently serves as Compaq's Senior Vice
President, Finance and Administration, and Chief Financial Officer and provides
his depth of knowledge of the IT industry and of Compaq. Mr. Clarke also brings
significant expertise in finance and general corporate matters. The integration
office now consists of more than 450 dedicated employees, supported by advisors
and divided into teams with specifically defined functions.

   By the time of completion of the merger, the integration office plans to
have established:

   .   an operating model and organization to design and implement a transition
       plan and provide internal clarity regarding asset and resource
       allocation and priorities, go-to-market strategy and customer account
       responsibilities;

   .   management structure, roles and responsibilities multiple layers into
       the organization, as well as compensation and human resource policies,
       which we believe will encourage our employees to focus on business
       performance and avoid the distraction of personal and organizational
       uncertainty;

   .   clear product roadmaps and investment protection programs, which we
       believe will give our customers a high degree of confidence in our
       ability to meet or exceed their business requirements without disrupting
       their existing relationship with us or their installed technology
       platform; and

   .   standard policies, practices and procedures to govern our relationships

   UNAUDITED PRO FORMA CONDENSED COMBINED CONSOLIDATED FINANCIAL STATEMENTS

   The following unaudited pro forma condensed combined consolidated balance
sheet as of October 31, 2001 and the unaudited pro forma condensed combined
consolidated statement of earnings for the year ended October 31, 2001 are
based on the historical financial statements of HP and Compaq after giving
effect to the merger as a purchase of Compaq by HP using the purchase method of
accounting and the assumptions and adjustments described in the accompanying
notes to the unaudited pro forma condensed combined consolidated financial
statements.

   The unaudited pro forma condensed combined consolidated balance sheet as of
October 31, 2001 is presented to give effect to the proposed merger as if it
occurred on October 31, 2001 and, due to different fiscal period ends, combines
the historical balance sheet for HP at October 31, 2001 and the historical
balance sheet of Compaq at September 30, 2001. The unaudited pro forma
condensed combined consolidated statement of earnings of HP and Compaq for the
year ended October 31, 2001 is presented as if the combination had taken place
on November 1, 2000 and, due to different fiscal period ends, combines the
historical results of HP for the year ended October 31, 2001 and the historical
results of Compaq for the twelve months ended September 30, 2001.

   Compaq's consolidated financial statements for the year ended December 31,
2001 included in its 2001 Annual Report on Form 10-K filed on January 30, 2002
and incorporated herein by reference included a cumulative effect of an
accounting change and certain reclassifications as a result of adoption in the
fourth quarter of 2001 of EITF 01-9, Accounting for Consideration Given by a
Vendor to a Customer or a Reseller of the Vendor's Products. The effect of this
accounting change has not been reflected in the historical financial
information of Compaq for the period ended September 30, 2001 included in these
unaudited pro forma combined consolidated financial statements.

   Under the purchase method of accounting, the total estimated purchase price,
calculated as described in Note 1 to these unaudited pro forma condensed
combined consolidated financial statements, is allocated to the net tangible
and intangible assets of Compaq acquired in connection with the merger, based
on their fair values as of the completion of the merger. Independent valuation
specialists are currently conducting an independent valuation in order to
assist management of HP in determining the fair values of a significant portion
of these assets. The preliminary work performed by the independent valuation
specialists has been considered in management's estimates of the fair values
reflected in these unaudited pro forma condensed combined consolidated
financial statements. A final determination of these fair values, which cannot
be made prior to the completion of the merger, will include management's
consideration of a final valuation prepared by the independent valuation
specialists. This final valuation will be based on the actual net tangible and
intangible assets of Compaq that exist as of the date of completion of the
merger.

   Further, the unaudited pro forma condensed combined consolidated financial
statements do not include any adjustments for liabilities resulting from
integration planning, as management of HP and Compaq are in the process of
making these assessments and estimates of these costs are not currently known.
However, liabilities ultimately will be recorded for severance or relocation
costs related to Compaq employees, costs of vacating some facilities (leased or
owned) of Compaq, or other costs associated with exiting activities of Compaq
that would affect amounts in the pro forma financial statements. In addition,
HP may incur significant restructuring charges upon completion of the merger or
in subsequent quarters for severance or relocation costs related to HP
employees, costs of vacating some facilities (leased or owned) of HP, or other
costs associated with exiting activities of HP.

   These unaudited pro forma condensed combined consolidated financial
statements have been prepared based on preliminary estimates of fair values.
They do not include liabilities resulting from integration planning which are
not presently estimable as discussed above. Amounts preliminarily allocated to
intangible assets with

                                      114



indefinite lives may significantly decrease or be eliminated and amounts
allocated to intangible assets with definite lives may increase significantly,
which could result in a material increase in amortization of intangible assets.
Therefore, the actual amounts recorded as of the completion of the merger may
differ materially from the information presented in these unaudited pro forma
condensed combined consolidated financial statements. In addition to the
receipt of the final valuation, the impact of ongoing integration activities,
the timing of completion of the merger and other changes in Compaq's net
tangible and intangible assets which occur prior to completion of the merger
could cause material differences in the information presented.

   The unaudited pro forma condensed combined consolidated financial statements
should be read in conjunction with the historical consolidated financial
statements and accompanying notes of HP and Compaq incorporated by reference
into this joint proxy statement/prospectus and the summary selected historical
consolidated financial data included elsewhere in this joint proxy
statement/prospectus. The unaudited pro forma condensed combined consolidated
financial statements are not intended to represent or be indicative of the
consolidated results of operations or financial condition of HP that would have
been reported had the merger been completed as of the dates presented, and
should not be taken as representative of the future consolidated results of
operations or financial condition of HP.

    Notes to Unaudited Pro Forma Condensed Combined Consolidated Financial
                                  Statements

1.  Basis of Pro Forma Presentation

   On September 4, 2001, HP and Compaq entered into a merger agreement which
will result in Compaq becoming a wholly-owned subsidiary of HP in a transaction
to be accounted for using the purchase method. The total estimated purchase
price of approximately $24.0 billion includes HP common stock valued at $22.5
billion, assumed stock options with a fair value of $1.4 billion and estimated
direct transaction costs of $150 million.

   The unaudited pro forma condensed combined consolidated financial statements
provide for the issuance of approximately 1.1 billion shares of HP common
stock, based upon an exchange ratio of 0.6325 of a share of HP common stock for
each outstanding share of Compaq common stock as of September 30, 2001. The
actual number of shares of HP common stock to be issued will be determined
based on the actual number of shares of Compaq common stock outstanding at the
completion of the merger. The average market price per share of HP common stock
of $20.92 is based on an average of the closing prices for a range of trading
days (August 30, August 31, September 4 and September 5, 2001) around the
announcement date (September 3, 2001) of the proposed merger. Based on the
total number of Compaq options outstanding at September 30, 2001, HP would
assume options to purchase approximately 171.7 million shares of HP common
stock at a weighted average exercise price of $37.26. The actual number of
options to be assumed will be determined based on the actual number of Compaq
options outstanding at the completion of the merger. The fair value of the
outstanding options was determined using a Black-Scholes valuation model. In
accordance with the terms of Compaq's equity-based plans, all of Compaq's
outstanding options which were granted prior to September 1, 2001 will vest
upon Compaq shareowner approval of the merger. Options outstanding as of
September 30, 2001 which were granted subsequent to August 31, 2001 are
insignificant.

   The estimated total purchase price of the Compaq merger is as follows (in
millions):

      Assumption of Compaq options...............................   1,400
                                                                  -------
         Total value of HP securities............................  23,850
      Estimated direct transaction costs.........................     150

      Total estimated purchase price............................. $24,000

   Under the purchase method of accounting, the total estimated purchase price
as shown in the table above is allocated to Compaq's net tangible and
intangible assets based on their estimated fair values as of the date of the
completion of the merger. Based on the preliminary independent valuation, and
subject to material changes upon receipt of the final valuation and other
factors as described in the introduction to these unaudited pro forma condensed
combined consolidated financial statements on page 114 of this joint proxy
statement/prospectus, the preliminary estimated purchase price is allocated as
follows (in millions):



                                                                  
   Preliminary estimated purchase price allocation:
      Net tangible assets........................................... $ 9,260
      Amortizable intangible assets:
          Customer contracts and lists, distribution agreements.....   2,400
          Developed and core technology, patents....................   1,500
          Other.....................................................     200
      Intangible assets with indefinite lives.......................   2,500
      Goodwill......................................................   9,083
      Net deferred tax liability....................................  (1,943)
      In-process research and development...........................   1,000
                                                                     -------
   Total preliminary estimated purchase price allocation............ $24,000
                                                                     =======


                                      118



   Of the total estimated purchase price, a preliminary estimate of $9.3
billion has been allocated to net tangible assets acquired and approximately
$4.1 billion has been allocated to amortizable intangible assets acquired. The
depreciation and amortization related to the fair value adjustment to net
tangible assets and the amortization related to the amortizable intangible
assets are reflected as pro forma adjustments to the unaudited pro forma
condensed combined consolidated statement of earnings.

   Developed technology, which comprises products that have reached
technological feasibility, includes products in most of Compaq's product lines,
principally the Compaq Himalaya, Proliant, Enterprise Storage Array, and
AlphaServer products. Core technology and patents represent a combination of
Compaq processes, patents and trade secrets developed through years of
experience in design and development: clustering, fault tolerant systems,
proprietary Alpha processor architecture, and storage area networks. Compaq's
technology and products are designed for hardware, software, solutions and
services, including enterprise storage and computing solutions, fault tolerant
business critical solutions, communication products, and desktop and portable
personal computers. This proprietary know-how can be leveraged by Compaq to
develop new technology and improved products and manufacturing processes. HP
expects to amortize the developed and core technology and patents on a
straight-line basis over an average estimated life of 6 years.

   Customer contracts represent existing contracts that relate primarily to
underlying customer relationships pertaining to the services provided by Compaq
Global Services, including contractual Customer Services relationships,
contractual Managed Services client relationships and contractual Systems
Integration consulting client relationships. Customer lists and distribution
agreements represent Compaq's relationships with its Enterprise and Personal
Systems installed base, and agreements with Enterprise value-added resellers.
HP expects to amortize the fair value of these assets, on a straight-line basis
over an average estimated life of 9 years.

   Of the total estimated purchase price, approximately $11.6 billion has been
allocated to goodwill and intangible assets with indefinite lives. Goodwill
represents the excess of the purchase price of an acquired business over the
fair value of the underlying net tangible and intangible assets. Intangible
assets with indefinite lives consist primarily of the estimated fair value
allocated to the Compaq trade name. The assumption used in the preliminary
valuation is that the Compaq trade name will not be amortized and will have an
indefinite remaining useful life based on many factors and considerations,
including the length of time that the Compaq name has been in use, the Compaq
brand awareness and market position, and the assumption of continued use of the
Compaq brand within HP's overall product portfolio. If HP management should
change the assumption used in the valuation, amounts preliminarily allocated to
intangible assets with indefinite lives may significantly decrease or be
eliminated, and amounts allocated to intangible assets with definite lives may
increase significantly, which could result in a material increase in
amortization of intangible assets.

   In accordance with the Statement of Financial Accounting Standards No. 142,
"Goodwill and Other Intangible Assets," goodwill and intangible assets with
indefinite lives resulting from business combinations completed subsequent to
June 30, 2001 will not be amortized but instead will be tested for impairment
at least annually (more frequently if certain indicators are present). In the
event that the management of the combined company determines that the value of
goodwill or intangible assets with indefinite lives has become impaired, the
combined company will incur an accounting charge for the amount of impairment
during the fiscal quarter in which the determination is made.

   Of the total estimated purchase price, a preliminary estimate of $1.0
billion has been allocated to in-process research and development and will be
charged to expense in the period during which the merger is completed. Due to
its non-recurring nature, the in-process research and development expense has
been excluded in the unaudited pro forma condensed combined consolidated
statement of earnings.

   Compaq is currently developing new products that qualify as in-process
research and development in multiple product areas. Projects which qualify as
in-process research and development represent those that have not yet reached
technological feasibility. Technological feasibility is defined as being
equivalent to completion of a beta-phase working prototype in which there is no
remaining risk relating to the development.

                                      119



   Compaq is currently involved in numerous research and development projects,
which are focused on developing new products, integrating new technologies,
improving product performance and broadening features and functionalities. The
principal research and development efforts of Compaq are directed within the
Enterprise and Personal System businesses. There is a risk that these
developments and enhancements will not be competitive with other products using
alternative technologies that offer comparable functionality.

   The value assigned to in-process research and development was determined by
considering the importance of each project to the overall development plan,
estimating costs to develop the purchased in-process research and development
into commercially viable products, estimating the resulting net cash flows from
the projects when completed and discounting the net cash flows to their present
value. The revenue estimates used to value the purchased in-process research
and development were based on estimates of relevant market sizes and growth
factors, expected trends in technology and the nature and expected timing of
new product introductions by Compaq and its competitors.

   The rates utilized to discount the net cash flows to their present value are
based on Compaq's weighted average cost of capital. The weighted average cost
of capital was adjusted to reflect the difficulties and uncertainties in
completing each project and thereby achieving technological feasibility, the
percentage of completion of each project, anticipated market acceptance and
penetration, market growth rates and risks related to the impact of potential
changes in future target markets. Based on these factors, discount rates that
range from 25%-42% were deemed appropriate for valuing the in-process research
and development.

   The estimates used in valuing in-process research and development were based
upon assumptions believed to be reasonable but which are inherently uncertain
and unpredictable. Assumptions may be incomplete or inaccurate, and
unanticipated events and circumstances may occur. In addition, some projects
which are currently in process may not be in process at completion of the
merger and new projects may be started prior to completion of the merger which
may be in process at the completion of the merger. Accordingly, actual results
may vary from the projected results.

2.  Pro Forma Adjustments

   Pro forma adjustments are necessary to reflect the estimated purchase price,
to adjust amounts related to Compaq's net tangible and intangible assets to a
preliminary estimate of their fair values, to reflect the amortization expense
related to the estimated amortizable intangible assets, to reflect changes in
depreciation and amortization expense resulting from the estimated fair value
adjustments to net tangible assets and to reflect the income tax effect related
to the pro forma adjustments.

   Intercompany balances or transactions between HP and Compaq were not
significant. No pro forma adjustments were required to conform Compaq's
accounting policies to HP's accounting policies. Certain reclassifications have
been made to conform Compaq's historical amounts to HP's presentation.

   The pro forma combined provision for income taxes does not reflect the
amounts that would have resulted had HP and Compaq filed consolidated income
tax returns during the periods presented.

   The unaudited pro forma condensed combined consolidated financial statements
do not include any adjustments for liabilities resulting from integration
planning, as management of HP and Compaq are in the process of making these
assessments, and estimates of these costs are not currently known. However,
liabilities ultimately will be recorded for severance or relocation costs
related to Compaq employees, costs of vacating some facilities (leased or
owned) of Compaq, or other costs associated with exiting activities of Compaq
that would affect amounts in the pro forma financial statements. In addition,
HP may incur significant restructuring charges upon completion of the merger or
in subsequent quarters for severance or relocation costs related to HP
employees, costs of vacating some facilities (leased or owned) of HP, and other
costs associated with exiting activities of HP.

                                      120



   HP has not identified any preacquisition contingencies where the related
asset, liability or impairment is probable and the amount of the asset,
liability or impairment can be reasonably estimated. Prior to the end of the
purchase price allocation period, if information becomes available which would
indicate it is probable that such events have occurred and the amounts can be
reasonably estimated, such items will be included in the purchase price
allocation.

   The pro forma adjustments included in the unaudited pro forma condensed
combined consolidated financial statements are as follows:

   (a) Adjustment to record the difference between the preliminary estimate of
       the fair value and the historical amount of Compaq's inventory.

   (b) Adjustment to record the difference between the preliminary estimate of
       the fair value and the historical amount of Compaq's property, plant and
       equipment and the resulting adjustment to depreciation expense, as
       follows (in millions):

       The adjustment to the valuation allowance related to Compaq's net
       deferred tax assets is based on a preliminary estimate of the tax assets
       which can be utilized by the combined company. Upon the finalization of
       the combined company's legal entity structure and the restructuring
       plans, the valuation allowance may be adjusted further to reflect the
       combined company's ability to utilize certain foreign net operating loss
       carryforwards and certain other tax losses and credits.

   (d) Adjustments to reflect the preliminary estimate of the fair value of
       amortizable intangible assets and the resulting increase in amortization
       expense, as follows (in millions):

   The pro forma basic and diluted earnings per share are based on the weighted
average number of shares of HP common stock outstanding and weighted average
number of Compaq common stock outstanding multiplied by the exchange ratio. All
HP historical and pro forma per-share amounts reflect the retroactive effects
of all HP stock splits including the two-for-one stock split in the form of a
stock dividend effective October 27, 2000.

                      COMPARISON OF RIGHTS OF HOLDERS OF
                    HP COMMON STOCK AND COMPAQ COMMON STOCK

   Upon completion of the merger, the shareowners of Compaq will become
shareowners of HP, and the HP certificate of incorporation and the HP bylaws
will govern the rights of former Compaq shareowners. Both HP and Compaq are
incorporated under Delaware law and are subject to the Delaware General
Corporation Law. The following is a summary of material differences between the
rights of holders of HP common stock and the rights of holders of Compaq common
stock. While we believe that this description covers the material differences
between the two, this summary may not contain all of the information that is
important to you.

Comparison of the Certificates of Incorporation and Bylaws of HP and Compaq


   The following is a summary of the material differences between the
provisions of the certificate of incorporation and bylaws of each of HP and
Compaq. This summary is not intended to be a complete discussion of the
respective certificates of incorporation and bylaws of HP and Compaq and it is
qualified in its entirety by reference to the applicable Delaware General
Corporation Law as well as by reference to the respective certificates of
incorporation and bylaws of HP and Compaq. You should carefully read this
entire joint proxy statement/prospectus and the other documents we refer to in
this joint proxy statement/prospectus for a more complete understanding of the
differences between being a shareowner of HP and being a shareowner of Compaq.
HP and Compaq have filed with the Securities and Exchange Commission their
respective certificates of incorporation and bylaws and will send copies of
these documents to you upon your request. See the section entitled "Where You
Can Find More Information" beginning on page 135 of this joint proxy
statement/prospectus.


   Authorized Capital Stock

   HP's certificate of incorporation authorizes the issuance of 9,900,000,000
shares of capital stock, consisting of:

   .   9,600,000,000 shares of common stock, par value $0.01 per share; and

   .   300,000,000 shares of preferred stock, par value $0.01 per share.

   Compaq's certificate of incorporation authorizes the issuance of
3,010,000,000 shares of capital stock, consisting of:

   .   3,000,000,000 shares of common stock, par value $0.01 per share; and

   .   10,000,000 shares of preferred stock, par value $0.01 per share.

   Size of the Board of Directors

   HP's certificate of incorporation provides that the number of directors
comprising the HP board of directors shall be no fewer than eight and no more
than 17. HP's certificate of incorporation further provides that the exact
number of directors comprising the HP board of directors shall be fixed, and
may be changed from time to time, within the foregoing limits, by an amendment
to HP's bylaws that has been duly adopted by the HP board of directors or HP
shareowners. HP's bylaws provide that within the range of eight to 17 directors
set forth in HP's certificate of incorporation, the exact number of directors
comprising the HP board of directors may be as fixed from time to time by the
HP board of directors. The HP board of directors currently has nine members.
Upon completion of the merger, the HP board of directors will have 13 members.


   Compaq's bylaws provide that the number of directors comprising the Compaq
board of directors may be no fewer than seven and no more than 12. The exact
number of directors comprising the Compaq board of directors may be changed at
any time by resolution of the Compaq board of directors. The Compaq board of
directors currently has seven members.


                                      123



    Cumulative Voting

   HP's certificate of incorporation provides that HP shareowners are entitled
to cumulate votes in connection with the election of directors.

   Compaq shareowners are not entitled to cumulate votes in connection with the
election of directors.

    Removal of Directors

   HP's bylaws provide that any director, or the entire HP board of directors,
may be removed with or without cause by the holders of a majority of the shares
then entitled to vote at an election of directors. However, if and so long as
shareowners are entitled to cumulative voting in connection with the election
of directors, if less than the entire HP board of directors is to be removed,
no individual director may be removed from the HP board of directors without
cause if the votes cast against such director's removal would be sufficient to
elect such director if then cumulatively voted in an election of the entire HP
board of directors.

   Compaq's certificate of incorporation and bylaws do not provide procedures
for the removal of Compaq directors. Under Delaware General Corporation Law,
any director, or the entire board of directors, may be removed with or without
cause by the affirmative vote of the holders of at least a majority of the
outstanding shares of a corporation entitled to vote in the election of
directors.

    Filling Vacancies on the Board of Directors

   HP's bylaws provide that vacancies on the HP board of directors may be
filled by a majority of the remaining directors, even if less than a quorum, or
by the sole remaining director. However, a vacancy created by the removal of a
director by the vote of the shareowners or by court order may be filled only by
the affirmative vote of a majority of the voting power of shares represented
and voting at a duly held shareowner meeting at which a quorum is present
(which shares voting affirmatively also constitute a majority of the required
quorum).

   HP's bylaws further provide that vacancies on the HP board of directors and
newly created directorships resulting from an increase in the authorized number
of directors elected by all of the HP shareowners having the right to vote as a
single class may be filled by a majority of the directors then in office,
although less than a quorum, or by a sole remaining director. However, whenever
the holders of any class or classes of stock, or any series of any class of
stock, are entitled to elect one or more directors by the provisions of HP's
certificate of incorporation, vacancies and newly created directorships of such
class or classes or series may be filled by a majority of the directors elected
by such class or classes or series then in office, or by a sole remaining
director so elected.

   HP's bylaws also provide that if, at the time of filling any vacancy or any
newly created directorship, the directors then in office constitute less than a
majority of the whole HP board of directors (as constituted immediately prior
to any such increase), then the Delaware Court of Chancery may, upon
application of any shareowner(s) holding at least 10% of the total number of
the then outstanding shares having the right to vote for such directors,
summarily order an election to be held to fill any such vacancies or newly
created directorships, or to replace the directors chosen by the directors then
in office, and such election shall be governed by the provisions of Section 211
of the Delaware General Corporation Law as far as applicable.

   Compaq's bylaws provide that any vacancy on the Compaq board of directors,
caused by death, resignation or removal from office of any director or
otherwise, or an increase in the authorized number of directors, may be filled
by a majority of the remaining directors or the sole remaining director.

   Ability to Call Special Meetings of the Board of Directors

   HP's bylaws provide that special meetings of the HP board of directors for
any purpose(s) may be called at any time by the chairman of the board of
directors, the vice chairman of the board of directors, the president, the

                                      124



chairman of the executive committee, any vice president, the secretary or a
majority of the directors then in office.

   Compaq's bylaws provide that special meetings of the Compaq board of
directors may be called by the chairman of the board of directors or the
president, or the secretary on the written request of any two directors.

   Ability to Call Special Meetings of Shareowners

   HP's bylaws provide that a special meeting of HP shareowners may be called
at any time by the HP board of directors, the chairman of the board of
directors, the vice chairman of the board of directors, the chairman of the
executive committee or the president, and special meetings of HP shareowners
may not be called by any other person(s).

   Compaq's bylaws provide that a special meeting of the Compaq shareowners may
be called at any time by the Compaq board of directors.

   Limitations on Business Transacted at Special Meetings of Shareowners

   HP's bylaws provide only such business shall be considered at a special
meeting of HP shareowners as shall have been stated in the notice for such
meeting.

   Compaq's bylaws do not limit shareowners to transacting only that business
specified in the notice of the meeting. Compaq's shareowners may propose
business at a special shareowners meeting if the proposal is brought before the
special shareowners meeting in accordance with Compaq's shareowners advance
notice procedures.

   Shareowner Nominations and Proposals at Shareowner Meetings

   HP's bylaws allow shareowners to nominate candidates for election to the HP
board of directors at any annual meeting of HP shareowners. In addition, HP's
bylaws allow shareowners to propose business to be conducted at any annual
meeting of HP shareowners. However, nominations of candidates for election to
the HP board of directors and proposals for business to be conducted at an
annual meeting may only be made by a shareowner who has given timely written
notice to the corporate secretary of HP before the annual meeting.

   Shareowner nominations of candidates for election to the HP board of
directors and proposals for business to be conducted at an annual meeting
cannot be brought before any annual meeting of HP shareowners unless the
nomination or proposal was brought before the annual meeting in accordance with
HP's shareowner advance notice procedures, as described in "Delivery and Notice
Requirements for Shareowner Nominations and Proposals" below.

   Compaq's bylaws allow shareowners to nominate candidates for election to the
Compaq board of directors at any annual or any special shareowner meeting at
which the Compaq board of directors has determined that directors will be
elected. In addition, Compaq's bylaws allow shareowners to propose business
before any annual or special shareowner meeting. However, nominations and
proposals may only be made by a shareowner who has given timely written notice
to the corporate secretary of Compaq before the annual or special shareowner
meeting.

   Shareowner nominations and proposals cannot be brought before any Compaq
shareowner meeting unless the nomination or proposal was brought before the
shareowner meeting in accordance with Compaq's shareowner advance notice
procedures, as described in "Delivery and Notice Requirements for Shareowner
Nominations and Proposals" below.

                                      125



   Delivery and Notice Requirements for Shareowner Nominations and Proposals

   HP's bylaws provide that for business to be properly brought before an
annual meeting of HP shareowners by an HP shareowner, or for a nomination of
candidates for election to the HP board of directors to be properly made by an
HP shareowner, such shareowner must have given timely notice of the proposal
for business to be conducted or of such nomination of candidates for election
to the HP board of directors in writing to the secretary of HP. To be timely,
notice of a proposal for business to be conducted at an annual meeting of HP
shareowners or of a nomination of candidates for election to the HP board of
directors must be delivered to, or mailed and received at, the principal
executive offices of HP during the earlier period to occur of (1) not later
than the close of business on the 90th day nor earlier than the close of
business on the 120th day prior to the first anniversary of the preceding
year's meeting, or (2) not less than the later of the close of business on the
45th day nor earlier than the close of business on the 75th day prior to the
first anniversary of the date on which HP first sent or gave its proxy
statement to shareowners for the preceding year's annual meeting. However, if
HP did not have an annual meeting of HP shareowners in the previous year or if
the date of the annual meeting is more than 30 days before or more than 60 days
after the anniversary date of the previous year's annual meeting, to be timely,
notice of a proposal for business to be conducted at an annual meeting of HP
shareowners or of a nomination of candidates for election to the HP board of
directors must be received not earlier than the close of business on the 120th
day prior to the meeting and not later than the close of business on the later
of (A) the 90th day prior to such meeting and (B) the 10th day following the
day HP publicly announces the date of the annual meeting for the current year.
In addition, for a proposal for business to be conducted at an annual meeting,
an HP shareowner must have delivered a proxy statement and form of proxy to
holders of a sufficient number of shares of HP common stock to approve the
proposal.

   Under Compaq's bylaws, notice of shareowner nominations or proposals to be
made at a shareowner meeting, to be timely, must be delivered to, or mailed and
received at, the principal executive offices of Compaq no less than 90 days
before the first anniversary of the immediately preceding year's annual meeting
of shareowners or, if the date of the meeting is more than 30 days before or
after the anniversary date, no less than 90 days before the date of the
meeting. However, if Compaq publicly announces the date of the shareowner
meeting less than 100 days before the date of the meeting, notice by the
shareowner must be received no later than the close of business on the tenth
day after Compaq publicly announces the date of the shareowner meeting.

   Shareowner Action by Written Consent in Lieu of a Shareowner Meeting

   HP's certificate of incorporation provides that no action may be taken by HP
shareowners except at an annual or special meeting of the shareowners called in
accordance with HP's bylaws, and that HP shareowners may not take action by
written consent.

   Compaq's bylaws provide that Compaq shareowners may take action at an annual
meeting or a special meeting of shareowners. In addition, Compaq shareowners
may take action without a meeting, without prior notice and without a vote, if
a written consent is signed by the holders of outstanding stock having not less
than the minimum number of votes necessary to take action at a meeting at which
all shares entitled to vote were present and voted.

   Amendment to Bylaws

   The HP board of directors is expressly authorized to make, alter, amend or
repeal HP's bylaws. HP's shareowners entitled to vote may also adopt, amend or
repeal HP's bylaws. However, HP's bylaws provide that the affirmative vote of
the holders of 66 2/3% of the outstanding shares entitled to vote is required
to amend or delete the provisions of HP's bylaws relating to:

   .   meetings of shareowners;

   .   the number, election and term of directors;

                                      126



   .   resignation and vacancies of directors;

   .   indemnification of officers and directors; and

   .   amendments to HP's bylaws.

   The Compaq board of directors is expressly authorized to adopt, amend, and
repeal Compaq's bylaws. Compaq's shareowners entitled to vote at any annual or
special meeting may also adopt, amend or repeal Compaq's bylaws in accordance
with Delaware General Corporation Law.

   Payment of Expenses Incurred by Directors and Officers in Connection with
   Legal Proceedings

   HP's bylaws provide that HP shall advance to any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding (whether civil, criminal, administrative
or investigative), by reason of the fact that such person is or was a director
or officer of HP, prior to the final disposition of the proceeding, all
expenses incurred by such person in connection with such proceeding. However,
such payment will be made only if HP receives an undertaking by or on behalf of
such person to repay all amounts advanced if it is ultimately determined that
such person is not entitled to be indemnified by HP as authorized by HP's
bylaws or otherwise.

   HP's bylaws also provide that HP shall not be required to advance expenses
to any director or officer in connection with any proceeding initiated by such
officer or director unless the proceeding was authorized in advance by the HP
board of directors.

   In addition, subject to some exceptions, HP will not advance expenses to an
officer of HP (unless such officer is also a director of HP) in any action,
suit or proceeding (whether civil, criminal, administrative or investigative),
if a determination is reasonably and promptly made by the HP board of directors
by a majority vote of a quorum consisting of directors who were not parties to
the proceeding (or if such quorum is not obtainable, or even if obtainable, a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion), that the facts known to the decision-making party at the time
such determination is made demonstrate clearly and convincingly that such
person acted in bad faith or in a manner that such person did not believe to be
in or not opposed to the best interests of HP.

   Compaq's bylaws provide that Compaq may pay the expenses (including
attorneys' fees) incurred by any Compaq director, nominee or officer in
defending a civil, criminal or investigative action, suit or proceeding, in
advance of the final disposition of that action, suit or proceeding. However,
such payment will be made only if Compaq receives an undertaking by or on
behalf of the director, nominee or officer to repay all amounts advanced if it
is ultimately determined that the director, nominee or officer is not entitled
to be indemnified by Compaq as authorized by Compaq's bylaws.

   No advance authorization by the Compaq board of directors is required prior
to the advance of expenses incurred by any Compaq director, nominee or officer
in connection with any proceeding initiated by such director, nominee or
officer.

Indemnification of Directors and Officers

   Each of HP and Compaq's certificate of incorporation contains a provision
eliminating the personal liability of its directors to the company or its
shareowners for monetary damages for breach of fiduciary duty as a director to
the fullest extent permitted by applicable law. The effect of this provision is
to eliminate the personal liability of directors to the company or its
shareowners for monetary damages for actions involving a breach of their
fiduciary duty of care, including any actions involving gross negligence. The
bylaws of HP generally provide for the mandatory indemnification of, and
payment of expenses incurred by, its directors and officers to the fullest
extent permitted by applicable law unless the proceedings were initiated by the
director or officer and not

                                      127



authorized by the board of directors. The bylaws of Compaq generally provide
for the mandatory indemnification of, and payment of expenses incurred by,
directors and officers to the fullest extent permitted by applicable law. Each
of HP and Compaq also have obtained directors' and officers' liability
insurance, which insures against liabilities that its directors and officers
may incur in such capacities. HP and Compaq have also entered into
indemnification agreements with their respective directors and officers. The
indemnification agreements provide indemnification to these directors and
officers under certain circumstances for acts or omissions which may not be
covered by directors' and officers' liability insurance.

   In addition, in accordance with the terms of the merger agreement and upon
completion of the merger, HP has agreed to cause the surviving corporation to
honor in all respects the obligations of Compaq under indemnification
agreements that existed between Compaq and Compaq's directors and officers
prior to completion of the merger. Furthermore, HP has agreed that the
certificate of incorporation and bylaws of the surviving corporation will
contain provisions indemnifying the directors and officers of Compaq at least
as favorable to the directors and officers of Compaq as those contained in
Compaq's certificate of incorporation and bylaws and that, for a period of six
years following completion of the merger, such provisions will not be modified
to adversely affect the rights of the directors, officers, employees or agents
of Compaq, unless required by law. HP also has agreed to cause the surviving
corporation to use all reasonable efforts to cause directors' and officers'
liability insurance policies covering the directors and officers of Compaq to
be maintained for a period of six years following completion of the merger on
terms comparable to the terms of the directors' and officers' liability
insurance policies maintained by Compaq as of the date of the merger agreement.

   Section 145 of the General Corporation Law of the State of Delaware
authorizes a court to award or a corporation's board of directors to grant
indemnification to directors and officers in terms that are sufficiently broad
to permit indemnification under certain circumstances for liabilities
(including reimbursement for expenses incurred) arising under the Securities
Act of 1933. Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers or persons
controlling HP or Compaq pursuant to the foregoing provisions, HP has been
informed that, in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Securities Act of
1933 and is therefore unenforceable.

Shareowner Rights Plans

   Under Delaware General Corporation Law, every corporation may create and
issue rights entitling the holders of such rights to purchase from the
corporation shares of its capital stock of any class or classes, subject to any
provisions in its certificate of incorporation. The price and terms of such
shares must be stated in the certificate of incorporation or in a resolution
adopted by the board of directors for the creation and issuance of such rights.

   Each of HP and Compaq have entered into a shareowner rights agreement. The
terms of the rights agreements are complex and not easily summarized,
particularly as they relate to the acquisition of common stock and to
exercisability. This summary may not contain all of the information that is
important to you. Accordingly, you should carefully read the HP rights
agreement and the Compaq rights agreement, both of which are incorporated by
reference into this joint proxy statement/prospectus in their entirety.

   HP management intends to recommend to the HP board of directors that it
terminate the HP rights plan following the completion of the merger.

   HP Shareowner Rights Plan

   On August 31, 2001, the HP board of directors declared a dividend
distribution of one right for each outstanding share of HP common stock to HP
shareowners of record at the close of business on September 17, 2001. Each
right is subject to the terms of HP's rights agreement.

                                      128



   HP's rights agreement provides that each share of HP's outstanding common
stock will have the right to purchase one one-thousandth of a share of HP's
Series A Participating Preferred Stock at an exercise price of $180.00, subject
to adjustment. Each share of HP common stock issued in connection with the
merger will have one right attached.

   The rights under HP's rights agreement currently are attached to and trade
only together with outstanding certificates representing HP common stock. The
rights will separate from HP common stock and be represented by separate and
distinct certificates approximately ten days after someone acquires or
commences a tender offer for 15% or more of the outstanding HP stock.

   After the rights separate from HP's common stock, certificates representing
the rights will be mailed to record holders of the common stock. Once
distributed, the rights certificates alone will represent the rights.

   All shares of HP common stock issued prior to the date the rights separate
from the common stock will be issued with the rights attached. The rights are
not exercisable until the date the rights separate from the common stock. The
rights will expire on September 17, 2011 unless earlier redeemed or exchanged
by HP.

   If an acquiror (which could be a person or group) obtains, or commences a
tender or exchange offer to obtain, 15% or more of HP common stock, then each
right will entitle the holder to purchase a number of shares of HP common stock
having a then current market value equal to two times the exercise price.

   Each right will entitle the holder to purchase a number of shares of common
stock of the acquiring entity having a then current market value of twice the
purchase price if an acquiror obtains 15% or more of HP common stock and any of
the following occurs:

    .  HP merges into another entity;

    .  an acquiring entity merges into HP; or

    .  HP sells more than 50% of its assets or earning power.

   Under HP's rights agreement, any rights that are or were owned by an
acquiror or its affiliates of more than 15% of HP's outstanding common stock
will be null and void.

   HP's rights agreement provides that after an acquiror obtains 15% or more of
HP's outstanding common stock, but less than 50% of HP's outstanding common
stock, the HP board of directors may, at its option, exchange all or part of
the then outstanding and exercisable rights (other than rights owned by the
acquiror or its affiliates) for HP common stock. In such an event, the exchange
ratio is one common share per right, adjusted to reflect any stock split, stock
dividend or similar transaction.

   At its option, the HP board of directors may redeem all of the outstanding
rights under the HP rights agreement at any time on or prior to the close of
business on the earlier of (1) the fifth day following the time that an
acquiror obtains 15% or more of HP's outstanding common stock or such later
date as may be determined by a majority of the board and publicly announced by
HP, or (2) September 17, 2011. The redemption price under HP's rights agreement
is $0.001 per right. The right to exercise the rights will terminate upon the
action of the HP board of directors ordering the redemption of the rights and
the only right of the holders of the rights will be to receive the redemption
price.

   Holders of rights will have no rights as shareowners of HP, including
without limitation the right to vote or receive dividends, simply by virtue of
holding the rights.

   The provisions of HP's rights agreement may be amended by the board of
directors prior to the date ten days after any person acquires 15% or more of
HP's common stock without approval of the holders of the rights.

                                      129



However, after the date any person acquires 15% or more of HP's common stock,
the rights agreement may not be amended in any manner which would adversely
affect the interests of the holders of the rights, excluding any interests of
the acquiror.

   The rights issued under HP's rights agreement are designed to protect and
maximize the value of the outstanding equity interests in HP in the event of an
unsolicited attempt by an acquiror to take over HP in a manner or on terms that
are not approved by the HP board of directors. The rights are designed to deter
unfair tactics, including a gradual accumulation of shares in the open market
of a 15% or greater position, followed by a merger or a partial or two-tier
tender offer that does not treat all HP shareowners equally.

   Subject to the restrictions described above, the rights may be redeemed by
HP at $0.001 per right at any time prior to the time when rights separate from
the common stock. Accordingly, the rights should not interfere with any merger
or business combination approved by the HP board of directors. The rights are
not intended to prevent a takeover of HP. However, the rights may have the
effect of rendering more difficult or discouraging an acquisition of HP deemed
undesirable by the HP board of directors. The rights will cause substantial
dilution to a person or group that attempts to acquire HP on terms or in a
manner not approved by the HP board of directors, except pursuant to an offer
conditioned upon redemption of the rights.

   Compaq Shareowner Rights Plan

   On September 3, 2001, the Compaq board of directors declared a dividend
distribution of one right for each outstanding share of Compaq common stock to
shareowners of record at the close of business on September 17, 2001, the
record date for the rights plan. Each right entitles the registered holder,
subject to the terms of the rights agreement, to purchase from Compaq a unit
consisting of one one-thousandth of a share of Compaq's Series A Junior
Participating Preferred Stock, par value $0.01 per share, at a purchase price
of $70 per unit, subject to adjustment.

   The rights currently are attached to and trade together with outstanding
certificates representing Compaq common stock. The rights will separate from
Compaq common stock and be represented by separate and distinct certificates
approximately ten business days after a person or group:

    .  acquires (other than pursuant to the merger agreement) 10% or more of
       the outstanding shares Compaq common stock;

    .  commences a tender or exchange offer for 10% or more of the outstanding
       shares Compaq common stock; or

    .  enters into an agreement (other than the merger agreement) with Compaq
       providing for an acquisition transaction (as defined in Compaq's rights
       agreement).

   For purposes of describing the rights plan, the date that the rights
separate from the common stock certificates is known as the distribution date.

   Until the distribution date:

    .  the rights will be evidenced by the Compaq common stock certificates and
       will be transferred only with such Compaq common stock certificates;

    .  new Compaq common stock certificates issued after the record date will
       contain a notation incorporating the rights agreement by reference; and

    .  the surrender for transfer of any certificates for Compaq common stock
       outstanding will also constitute the transfer of the rights associated
       with the Compaq common stock represented by the certificate.

                                      130



   The rights are not exercisable until the distribution date and will expire
at 5:00 p.m. (Texas time) on September 3, 2011, unless the date is extended or
the rights are earlier redeemed or exchanged by Compaq as described below.

   As soon as practicable after the distribution date, rights certificates will
be mailed to holders of record of the Compaq common stock as of the close of
business on the distribution date and, thereafter, the separate rights
certificates alone will represent the rights. Except as otherwise determined by
the Compaq board of directors, only shares of Compaq common stock issued prior
to the distribution date will be issued with rights.

   If a person or group acquires or has the right to acquire 10% or more of the
outstanding shares of Compaq common stock, other than as a result of
repurchases of stock by Compaq or inadvertent actions by institutional or other
shareowners, and except pursuant to an offer for all outstanding shares of
Compaq common stock which the independent directors of Compaq determine to be
fair and in the best interests of Compaq and its shareowners, and other than
pursuant to the merger agreement, then each right will entitle the holder
(other than the acquiror or its affiliates) to purchase a number of shares of
Compaq common stock having a market value equal to two times the exercise price
of the right.

   If, at any time following the date that a person or group acquires or has
the right to acquire 10% or more of the outstanding shares of Compaq common
stock (other than pursuant to the merger agreement):

    .  Compaq engages in a merger or other business combination transaction in
       which Compaq is not the surviving corporation;

    .  Compaq engages in a merger or other business combination transaction in
       which Compaq is the surviving corporation and the Compaq common stock is
       changed or exchanged; or

    .  Compaq sells more than 50% of its assets or earning power;

then, each holder of a right (other than the acquiror or its affiliates) shall
thereafter have the right to receive, upon exercise, capital stock of the
acquiring company having a market value equal to two times the exercise price
of the right.

   Under Compaq's rights agreement, any rights that are or were owned by a
person or group that acquired or has the right to acquire 10% or more of
Compaq's outstanding common stock will be null and void.

   Compaq's rights agreement contains exchange provisions which provide that
after a person or group acquires or has the right to acquire 10% or more of
Compaq's outstanding common stock (other than pursuant to the merger agreement)
but less than 50% of Compaq's outstanding common stock, the Compaq board of
directors may, at its option, exchange all or part of the then outstanding and
exercisable rights (other than rights owned by the acquiror or its affiliates)
at an exchange ratio of one share of Compaq common stock or one one-thousandth
of a share of Compaq Series A Junior Participating Preferred Stock (or of a
share of a class or series of Compaq's preferred stock having equivalent
rights) per right, subject to adjustment.

   At any time until ten business days following the public announcement that a
person or group acquired or has the right to acquire 10% or more of Compaq
common stock (other than pursuant to the merger agreement), Compaq may redeem
the rights in whole, but not in part, at a price of $0.001 per right (payable
in cash, Compaq common stock or other consideration deemed appropriate by the
Compaq board of directors). Immediately upon the action of the Compaq board of
directors ordering redemption of the rights, the rights will terminate and the
only right of the holders will be to receive the $0.001 redemption price.

   The Compaq rights agreement includes a provision that, if a majority of the
Compaq board of directors is replaced within 180 days after a third party
publicly announces that it intends to engage in a transaction with Compaq that
would result in the third party acquiring or obtaining the right to acquire 10%
or more of Compaq common stock (other than pursuant to the merger agreement),
then, for 180 days after its election (this period is

                                      131



known as the special period) the succeeding Compaq board of directors may
redeem the rights only if it undertakes value-enhancing procedures. In some
circumstances, the value-enhancing procedures could include the receipt of an
opinion of a disinterested financial advisor that the redemption of the rights
would be in the best interest of Compaq and its shareowners.

   Prior to the distribution date, the Compaq board of directors may amend the
provisions of the Compaq rights agreement without the approval of the holders
of the rights. After the distribution date, the Compaq board of directors may
amend the provisions of the rights agreement in order to:

    .  cure any ambiguity;

    .  make changes which do not adversely affect the interests of holders of
       rights (other than the interests of an acquiror); or

    .  shorten or lengthen any time period under the rights agreement.

   No amendment may be made to the rights agreement during the special period
or at a time when the rights are not redeemable, except to cure any ambiguity
or correct or supplement any provision contained in the rights agreement which
may be defective or inconsistent with any other provision therein.

   Until a right is exercised, the holder thereof, as such, will have no rights
as a shareowner of Compaq, including, without limitation, the right to vote or
to receive dividends.

   The rights may have anti-takeover effects. The rights will cause substantial
dilution to a person or group that attempts to acquire Compaq in a manner which
causes the rights to become discount rights unless the offer is conditional
upon a substantial number of rights being acquired. Accordingly, the existence
of the rights may deter acquirors from making takeover proposals or tender
offers. However, the rights are not intended to prevent a takeover, but rather
are designed to enhance the ability of the Compaq board of directors to
negotiate with an acquiror on behalf of all the shareowners.

   Pursuant to Compaq's bylaws, the rights plan will terminate if the rights
plan is not approved by the affirmative vote of the holders of a majority of
the shares of Compaq's common stock voting on the matter at Compaq's next
annual meeting of shareowners.

                                      132



                        FUTURE HP SHAREOWNER PROPOSALS

   The time for HP shareowners to submit proposals for inclusion in HP's proxy
statement for HP's 2002 annual meeting of shareowners in accordance with the
standards contained in Securities and Exchange Commission Rule 14a-8 and HP's
bylaws has passed. Accordingly, no new shareowner proposals may be submitted to
HP for inclusion in HP's proxy statement for HP's 2002 annual meeting of
shareowners. However, if the date of HP's 2002 shareowner meeting is moved more
than 30 days before or after the anniversary date of the prior year's meeting,
the deadline for inclusion of proposals in HP's proxy statement is a reasonable
time before HP begins to print and mail its proxy materials. The time to submit
notice of shareowner proposals or nominations to be raised from the floor of
HP's 2002 annual meeting of shareowners has also passed. However, if the date
of HP's 2002 shareowner meeting is moved more than 30 days before or 60 days
after the anniversary date of the prior year's meeting, then, in order to raise
a proposal or nomination from the floor, notice must be received by the
corporate secretary of HP no earlier than the close of business 120 days prior
to the meeting and no later than the close of business on the later of the
following two dates:

   .   90 days prior to the meeting; and

   .   10 days after public announcement of the meeting date.

   In addition, in order to raise a proposal from the floor, the shareowner
must comply with HP's bylaws, including requirements to have delivered a proxy
statement and form of proxy to holders of a sufficient number of shares of HP
common stock to approve the proposal and to provide specified information. In
addition, HP's bylaws provide that a nomination for director must include a
statement by the nominee acknowledging that he or she will owe a fiduciary
obligation exclusively to the corporation and its shareowners. You may contact
the HP corporate secretary at HP's principal executive offices for a copy of
the relevant provisions of HP's bylaws regarding the requirements for making
shareowner proposals and nominations for directors.

                      FUTURE COMPAQ SHAREOWNER PROPOSALS

   If the merger is not completed, Compaq will hold its 2002 annual meeting of
shareowners. The time for Compaq shareowners to submit proposals for inclusion
in Compaq's proxy statement for Compaq's 2002 annual meeting in accordance with
the standards contained in Securities and Exchange Commission Rule 14a-8 has
passed. Accordingly, no new shareowner proposals may be submitted to Compaq for
inclusion in Compaq's proxy statement for its 2002 meeting of shareowners.

   In the event the merger is not completed and the Compaq 2002 annual meeting
is held, if a shareowner intends to present a proposal for consideration or
make a nomination for director at the 2002 annual meeting outside the processes
of Securities and Exchange Commission Rule 14a-8, the shareowner must meet the
requirements of Compaq's bylaws which require, in general, that notice must be
received by the corporate secretary of Compaq no earlier than 90 days in
advance of the anniversary date of the prior year's annual meeting (or if the
date of the meeting is more than 30 days before the anniversary date of the
prior year's annual meeting, the shareowner's notice must be received by the
corporate secretary of Compaq no earlier than 90 days in advance of the meeting
date). In the event that public disclosure of the date of the meeting is made
less than 100 days in advance of the date of the meeting, notice of the
shareowner must be received by the corporate secretary of Compaq not later than
the close of business on the tenth day following public disclosure of the
meeting date. A copy of the relevant bylaws provision may be obtained by
written request to Compaq Computer Corporation, P.O. Box 69200, Houston, Texas
77269-2000, Attention: Corporate Secretary.

                                 LEGAL MATTERS

   Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo Alto,
California will pass upon the validity of the shares of HP common stock offered

Delaware Law.

   1.4 Certificate of Incorporation and Bylaws.  At the Effective Time, the
Certificate of Incorporation of Compaq shall be amended and restated in its
entirety to be identical to the Certificate of Incorporation of Merger Sub, as
in effect immediately prior to the Effective Time, until thereafter amended in

   1.6 Effect on Capital Stock.  Subject to the terms and conditions of this
Agreement, at the Effective Time, by virtue of the Merger and without any
action on the part of HP, Merger Sub, Compaq or the holders of any shares of
capital stock of Compaq, the following shall occur:

      (a) Compaq Common Stock.  Each share of the Common Stock, par value $0.01
   per share, of Compaq (together with the associated Compaq Right (as defined
   in Section 2.2(a)) under the Compaq Rights Agreement (as defined in Section
   2.2(a)) ("Compaq Common Stock") issued and outstanding immediately prior to
   the Effective Time, other than any shares of Compaq Common Stock to be
   canceled pursuant to Section 1.6(c), will be canceled and extinguished and
   automatically converted (subject to Section 1.6(f)) into the right to
   receive 0.6325 of a validly issued, fully paid and nonassessable share (the
   "Exchange Ratio") of the Common Stock, par value $0.01 per share, of HP
   (together with any associated HP Right (as defined in Section 3.2(a)) under
   the HP Rights Agreement (as defined in Section 3.2(a)) ("HP Common Stock")
   upon surrender of the certificate representing such share of Compaq Common
   Stock in the manner provided in Section 1.7 (or in the case of a lost,
   stolen or destroyed certificate, upon delivery of an affidavit (and bond, if
   required) in the manner provided in Section 1.9).

      (b) Repurchase Rights.  If any shares of Compaq Common Stock outstanding
   immediately prior to the Effective Time are unvested or are subject to a
   repurchase option, risk of forfeiture or other condition under any
   applicable restricted stock purchase agreement or other agreement with
   Compaq, then the shares of HP Common Stock issued in exchange for such
   shares of Compaq Common Stock will also be unvested and subject to the same
   repurchase option, risk of forfeiture or other condition, and the
   certificates representing such shares of HP Common Stock may accordingly be
   marked with appropriate legends. Compaq shall take all action that may be
   necessary to ensure that, from and after the Effective Time, the Surviving
   Corporation is entitled to exercise any such repurchase option or other
   right set forth in any such restricted stock purchase agreement or other
   agreement.

                                      A-2



      (c) Cancellation of Treasury and HP Owned Stock.  Each share of Compaq

   Subsidiary of Compaq or of HP immediately prior to the Effective Time shall
   be canceled and extinguished without any conversion thereof.

      (d) Capital Stock of Merger Sub.  Each share of common stock, par value
   $0.01, of Merger Sub (the "Merger Sub Common Stock") issued and outstanding
   prior immediately to the Effective Time shall be converted into one validly
   issued, fully paid and nonassessable shares of common stock, par value $0.01
   per share, of the Surviving Corporation.

   Compaq's Employee Stock Purchase Plan and any other employee stock purchase
   plan of Compaq (collectively, the "Compaq Purchase Plans") shall be treated
   as set forth in Section 5.9(c).

      (f) Fractional Shares.  No fraction of a share of HP Common Stock will be
   issued by virtue of the Merger, but in lieu thereof each holder of shares of
   Compaq Common Stock who would otherwise be entitled to a fraction of a share
   of HP Common Stock (after aggregating all fractional shares of HP Common
   Stock that otherwise would be received by such holder) shall, upon surrender
   of such holder's Certificate(s) (as defined in Section 1.7(c)), receive from
   HP an amount of cash (rounded to the nearest whole cent), without interest,
   equal to the product of: (i) such fraction, multiplied by (ii) the average
   closing price of one share of HP Common Stock for the ten (10) most recent
   trading days that HP Common Stock has traded ending on the trading day one
   day prior to the Effective Time, as reported on the New York Stock Exchange,
   Inc. ("NYSE") Composite Transactions Tape.

   to reflect fully the appropriate effect of any stock split, reverse stock
   split, stock dividend (including any dividend or distribution of securities
   convertible into HP Common Stock or Compaq Common Stock), reorganization,
   recapitalization, reclassification or other like change with respect to HP
   Common Stock or Compaq Common Stock having a record date on or after the
   date hereof and prior to the Effective Time.

   1.7 Surrender of Certificates.

   (a) Exchange Agent.  HP shall select Computershare Investor Services LLC or
another institution reasonably satisfactory to Compaq to act as the exchange
agent (the "Exchange Agent") in the Merger.

   (b) HP to Provide Common Stock.  Promptly after the Effective Time, HP shall
enter into an agreement with the Exchange Agent, reasonably satisfactory to
Compaq, which shall provide that HP shall make available to the Exchange Agent
for exchange in accordance with this Article I, the shares of HP Common Stock
issuable pursuant to Section 1.6(a) in exchange for outstanding shares of
Compaq Common Stock. In addition, HP shall make available as necessary from
time to time after the Effective Time as needed, cash in an amount sufficient
for payment in lieu of fractional shares pursuant to Section 1.6(f) and any
dividends or distributions which holders of shares of Compaq Common Stock may
be entitled pursuant to Section 1.7(d). Any cash and HP Common Stock deposited
with the Exchange Agent shall hereinafter be referred to as the "Exchange Fund."


   (c) Exchange Procedures.  Promptly after the Effective Time, HP shall cause
the Exchange Agent to mail to each holder of record (as of the Effective Time)
a certificate or certificates (the "Certificates") which immediately prior to
the Effective Time represented outstanding shares of Compaq Common Stock whose
shares were converted into the right to receive shares of HP Common Stock
pursuant to Section 1.6(a), cash in lieu of any fractional shares pursuant to
Section 1.6(f) and any dividends or other distributions pursuant to
Section 1.7(d): (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Exchange Agent and shall be in
such form and have such other provisions as HP may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing whole shares of HP Common Stock,


                                      A-3



cash in lieu of any fractional shares pursuant to Section 1.6(f) and any
dividends or other distributions pursuant to Section 1.7(d). Upon surrender of
Certificates for cancellation to the Exchange Agent or to such other agent or
agents as may be appointed by HP, together with such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto
and such other documents as may reasonably be required by the Exchange Agent,
the holder of such Certificates shall be entitled to receive in exchange
therefor the number of whole shares of HP Common Stock (after taking into
account all Certificates surrendered by such holder) to which such holder is
entitled pursuant to Section 1.6(a) (which shall be in uncertificated book
entry form unless a physical certificate is requested or is otherwise required
by applicable law or regulation), payment in lieu of fractional shares which
such holder has the right to receive pursuant to Section 1.6(f) and any
dividends or distributions payable pursuant to Section 1.7(d), and the
Certificates so surrendered shall forthwith be canceled. Until so surrendered,
outstanding Certificates will be deemed from and after the Effective Time, for
all corporate purposes, to evidence the ownership of the number of full shares
of HP Common Stock into which such shares of Compaq Common Stock shall have
been so converted and the right to receive an amount in cash in lieu of the
issuance of any fractional shares in accordance with Section 1.6(f) and any
dividends or distributions payable pursuant to Section 1.7(d).

   (d) Distributions With Respect to Unexchanged Shares.  No dividends or other
distributions declared or made after the date hereof with respect to HP Common
Stock with a record date after the Effective Time and no payment in lieu of
fractional shares pursuant to Section 1.6(f) will be paid to the holders of any
unsurrendered Certificates with respect to the shares of HP Common Stock
represented thereby until the holders of record of such Certificates shall
surrender such Certificates. Subject to applicable law, following surrender of
any such Certificates, the Exchange Agent shall deliver to the record holders
thereof, without interest (i) promptly after such surrender, the number of
whole shares of HP Common Stock issued in exchange therefor along with payment
in lieu of fractional shares pursuant to Section 1.6(f) and the amount of any
such dividends or other distributions with a record date after the Effective
Time and theretofore paid with respect to such whole shares of HP Common Stock
and (ii) at the appropriate payment date, the amount of dividends or other
distributions with a record date after the Effective Time and a payment date
subsequent to such surrender payable with respect to such whole shares of HP
Common Stock.

   (e) Transfers of Ownership.  If shares of HP Common Stock are to be issued
in a name other than that in which the Certificates surrendered in exchange
therefor are registered, it will be a condition of the issuance thereof that
the Certificates so surrendered will be properly endorsed and otherwise in
proper form for transfer and that the Persons (as defined in Section 8.3(d))
requesting such exchange will have paid to HP or any agent designated by it any
transfer or other Taxes (as defined in Section 2.6) required by reason of the
issuance of shares of HP Common Stock in any name other than that of the
registered holder of the Certificates surrendered, or established to the
satisfaction of HP or any agent designated by it that such Tax has been paid or
is not payable.

   (f) Required Withholding.  Each of the Exchange Agent and the Surviving
Corporation shall be entitled to deduct and withhold from any consideration
payable or otherwise deliverable pursuant to this Agreement to any holder or
former holder of Compaq Common Stock such amounts as may be required to be
deducted or withheld therefrom under the Code or under any provision of state,
local or foreign Tax law or under any other applicable Legal Requirement (as
defined in Section 2.2(d)). To the extent such amounts are so deducted or
withheld, the amount of such consideration shall be treated for all purposes
under this Agreement as having been paid to the Person to whom such
consideration would otherwise have been paid.

   (g) No Liability.  Notwithstanding anything to the contrary in this Section
1.7, neither the Exchange Agent, the Surviving Corporation nor any party hereto
shall be liable to a holder of shares of HP Common Stock or Compaq Common Stock
for any amount properly paid to a public official pursuant to any applicable
abandoned property, escheat or similar law.

                                      A-4



   (h) Investment of Exchange Fund.  The Exchange Agent shall invest any cash
included in the Exchange Fund as directed by HP on a daily basis; provided that
no such investment or loss thereon shall affect the amounts payable to Compaq
stockholders pursuant to this Article I. Any interest and other income
resulting from such investment shall become a part of the Exchange Fund, and
any amounts in excess of the amounts payable to Compaq stockholders pursuant to
this Article I shall promptly be paid to HP.

   (i) Termination of Exchange Fund.  Any portion of the Exchange Fund which
remains undistributed to the holders of Certificates six (6) months after the
Effective Time shall, at the request of the Surviving Corporation, be delivered
to the Surviving Corporation or otherwise on the instruction of the Surviving
Corporation, and any holders of the Certificates who have not surrendered such
Certificates in compliance with this Section 1.7 shall after such delivery to
Surviving Corporation look only to the Surviving Corporation for the shares of
HP Common Stock pursuant to Section 1.6(a), cash in lieu of any fractional
shares pursuant to Section 1.6(f) and any dividends or other distributions
pursuant to Section 1.7(d) with respect to the shares of Compaq Common Stock
formerly represented thereby. Any such portion of the Exchange Fund remaining
unclaimed by holders of shares of Compaq Common Stock immediately prior to such
time as such amounts would otherwise escheat to or become property of any
Governmental Entity (as defined in Section 2.3(c)) shall, to the extent
permitted by law, become the property of HP free and clear of any claims or
interest of any Person previously entitled thereto.

   1.8 No Further Ownership Rights in Compaq Common Stock.  All shares of HP
Common Stock issued upon the surrender for exchange of shares of Compaq Common
Stock in accordance with the terms hereof (including any cash paid in respect
thereof pursuant to Section 1.6(f) and 1.7(d)) shall be deemed to have been
issued in full satisfaction of all rights pertaining to such shares of Compaq
Common Stock, and there shall be no further registration of transfers on the
records of the Surviving Corporation of shares of Compaq Common Stock which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates are presented to the Surviving Corporation for any
reason, they shall be canceled and exchanged as provided in this Article I.

   1.9 Lost, Stolen or Destroyed Certificates.  In the event any Certificates
shall have been lost, stolen or destroyed, the Exchange Agent shall issue in
exchange for such lost, stolen or destroyed Certificates, upon the making of an
affidavit of that fact by the holder thereof, such shares of HP Common Stock,
cash for fractional shares, if any, as may be required pursuant to Section
1.6(f) and any dividends or distributions payable pursuant to Section 1.7(d);
provided, however, that HP may, in its discretion and as a condition precedent
to the issuance thereof, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against HP, Compaq or the Exchange
Agent with respect to the Certificates alleged to have been lost, stolen or
destroyed.

   1.10 Tax Consequences.  It is intended by the parties hereto that the Merger
shall constitute a reorganization within the meaning of Section 368(a) of the
Code. The parties hereto adopt this Agreement as a plan of reorganization
within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3(a).

   1.11 Further Action.  At and after the Effective Time, the officers and
directors of HP and the Surviving Corporation will be authorized to execute and
deliver, in the name and on behalf of Compaq and Merger Sub, any deeds, bills
of sale, assignments or assurances and to take and do, in the name and on
behalf of Compaq and Merger Sub, any other actions and things to vest, perfect
or confirm of record or otherwise in the Surviving Corporation any and all
right, title and interest in, to and under any of the rights, properties or
assets acquired or to be acquired by the Surviving Corporation as a result of,
or in connection with, the Merger.

                                  ARTICLE II

                   REPRESENTATIONS AND WARRANTIES OF COMPAQ

   Compaq represents and warrants to HP and Merger Sub, subject to the
exceptions specifically disclosed in writing in the disclosure letter supplied
by Compaq to HP dated as of the date hereof and certified by a duly authorized
officer of Compaq (the "Compaq Disclosure Letter"), as follows:

   2.1 Organization; Standing and Power; Charter Documents; Subsidiaries.

   (a) Organization; Standing and Power.  Compaq and each of its Subsidiaries
(as defined below) is a corporation or other organization duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation or organization, has the requisite power and authority to own,
lease and operate its properties and to carry on its business as now being
conducted, except where the failure to be so organized, existing and in good
standing would not reasonably be expected to have a Material Adverse Effect (as
defined in Section 8.3(c)) on Compaq, and is duly qualified and in good
standing to do business in each jurisdiction in which the nature of its
business or the ownership or leasing of its properties makes such qualification
necessary other than in such jurisdictions where the failure to so qualify or
to be good standing, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect on Compaq. For purposes of this
Agreement, "Subsidiary," when used with respect to any party, shall mean any
corporation or other organization, whether incorporated or unincorporated, at
least a majority of the securities or other interests of which having by their
terms ordinary voting power to elect a majority of the Board of Directors or
others performing similar functions with respect to such corporation or other
organization is directly or indirectly owned or controlled by such party or by
any one or more of its Subsidiaries, or by such party and one or more of its
Subsidiaries.

   (b) Charter Documents.  Compaq has delivered or made available to HP: (i) a
true and correct copy of the Certificate of Incorporation (including any
Certificate of Designations) and Bylaws of Compaq, each as amended to date
(collectively, the "Compaq Charter Documents") and (ii) the certificate of
incorporation and bylaws, or like organizational documents (collectively,
"Subsidiary Charter Documents"), of each of its Significant Subsidiaries (as
defined in Rule 1-02 of Regulation S-X of the Securities and Exchange
Commission (the "SEC")), and each such instrument is in full force and effect.
Compaq is not in violation of any of the provisions of the Compaq Charter
Documents and each Subsidiary is not in violation of its respective Subsidiary
Charter Documents, except in the case of a Subsidiary, as would not reasonably
be expected to have a Material Adverse Effect on Compaq.

   (c) Subsidiaries.  Exhibit 21 to Compaq's Annual Report on Form 10-K for the
fiscal year ended December 31, 2000 includes all the Subsidiaries of Compaq
which are Significant Subsidiaries. All the outstanding shares of capital stock
of, or other equity interests in, each such Significant Subsidiary have been
validly issued and are fully paid and nonassessable and are, except as set
forth in such Exhibit 21, owned directly or indirectly by Compaq, free and
clear of all pledges, claims, liens, charges, encumbrances, options and
security interests of any kind or nature whatsoever (collectively, "Liens"),
including any restriction on the right to vote, sell or otherwise dispose of
such capital stock or other ownership interests, except for restrictions
imposed by applicable securities laws.

Legal Requirement applicable to Compaq or any of its Subsidiaries or by which
Compaq or any of its Subsidiaries or any of their respective properties is
bound or affected, or (iii) result in any material breach of or constitute a
material default (or an event that with notice or lapse of time or both would
become a material default) under, or impair Compaq's rights or alter the rights
or obligations of any third party under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of a material Lien on any of the material properties or assets of
Compaq or any of its Subsidiaries pursuant to, any Compaq Material Contract (as
defined in Section 2.14). Section 2.3(b) of the Compaq Disclosure Letter lists
all consents, waivers and approvals under any of Compaq's or any of its
Subsidiaries' Contracts required to be obtained in connection with the
consummation of the transactions contemplated hereby, which, if individually or
in the aggregate not obtained, would result in a Material Adverse Effect on
Compaq or the Surviving Corporation.

   (c) Necessary Consents.  No consent, approval, order or authorization of, or
registration, declaration or filing with any supranational, national, state,
municipal, local or foreign government, any instrumentality,

                                      A-8



subdivision, court, administrative agency or commission or other governmental
authority or instrumentality, or any quasi-governmental or private body
exercising any regulatory, taxing, importing or other governmental or
quasi-governmental authority (a "Governmental Entity") is required to be
obtained or made by Compaq in connection with the execution and delivery of
this Agreement or the consummation of the Merger and other transactions
contemplated hereby, except for: (i) the filing of the Certificate of Merger
with the Secretary of State of the State of Delaware and appropriate documents
with the relevant authorities of other states in which Compaq and/or HP are
qualified to do business, (ii) the filing of the Prospectus/Proxy Statement (as
defined in Section 2.15) with the SEC in accordance with the Securities
Exchange Act of 1934, as amended (the "Exchange Act") and the effectiveness of
the Registration Statement (as defined in Section 2.15), (iii) such consents,

Community, as amended (the "EC Merger Regulation"), (iv) the consents listed on
Section 2.3(c) of the Compaq Disclosure Letter; (v) such consents, approvals,
orders, authorizations, registrations, declarations and filings as may be
required under applicable state securities or "blue sky" laws and the
securities laws of any foreign country, and (vi) such other consents,
authorizations, filings, approvals and registrations which if not obtained or
made would not be material to Compaq or HP or materially adversely affect the
ability of the parties hereto to consummate the Merger within the time frame in
which the Merger would otherwise be consummated in the absence of the need for
such consent, approval, order, authorization, registration, declaration or
filings. The consents, approvals, orders, authorizations, registrations,
declarations and filings set forth in (i) through (v) are referred to herein as
the "Necessary Consents."

   2.4 SEC Filings; Financial Statements.

   (a) SEC Filings.  Compaq has filed all required registration statements,
prospectuses, reports, schedules, forms, statements and other documents
(including exhibits and all other information incorporated by reference)
required to be filed by it with the SEC since January 1, 1998. Compaq has made
available to HP all such registration statements, prospectuses, reports,
schedules, forms, statements and other documents in the form filed with the
SEC. All such required registration statements, prospectuses, reports,
schedules, forms, statements and other documents (including those that Compaq
may file subsequent to the date hereof), as amended, are referred to herein as
the "Compaq SEC Reports." As of their respective dates, the Compaq SEC Reports
(i) were prepared in accordance and complied in all material respects with the
requirements of the Securities Act of 1933, as amended (the "Securities Act"),
or the Exchange Act, as the case may be, and the rules and regulations of the
SEC thereunder applicable to such Compaq SEC Reports and (ii) did not at the
time they were filed contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading, except to the extent corrected prior to the date
hereof by a subsequently filed Compaq SEC Report. None of Compaq's Subsidiaries
is required to file any forms, reports or other documents with the SEC.

   (b) Financial Statements.  Each of the consolidated financial statements
(including, in each case, any related notes thereto) contained in the Compaq
SEC Reports (the "Compaq Financials"), including each Compaq SEC Report filed
after the date hereof until the Closing: (i) complied as to form in all
material respects with the published rules and regulations of the SEC with
respect thereto, (ii) was prepared in accordance with United States generally
accepted accounting principles ("GAAP") applied on a consistent basis
throughout the periods involved (except as may be indicated in the notes
thereto or, in the case of unaudited interim financial statements, as may be
permitted by the SEC on Form 10-Q, 8-K or any successor form under the Exchange
Act), and (iii) fairly presented in all material respects the consolidated
financial position of Compaq and its consolidated Subsidiaries as at the
respective dates thereof and the consolidated results of Compaq's operations
and cash flows for the periods indicated. The balance sheet of Compaq contained
in the Compaq SEC Reports as of December 31, 2000 is hereinafter referred to as
the "Compaq Balance Sheet." Except as disclosed in the Compaq Financials, since
the date of the Compaq Balance Sheet and through the date hereof, neither
Compaq nor any of its Subsidiaries has any liabilities required under GAAP to
be set forth on a consolidated balance sheet

                                      A-9



(absolute, accrued, contingent or otherwise) which, individually or in the
aggregate, would be reasonably expected to have a Material Adverse Effect on
Compaq, except for liabilities incurred since the date of the Compaq Balance
Sheet in the ordinary course of business consistent with past practices and
liabilities incurred pursuant to this Agreement.

   2.5 Absence of Certain Changes or Events.  Since the date of the Compaq
Balance Sheet and through the date hereof there has not been: (i) any Material
Adverse Effect on Compaq, (ii) any declaration, setting aside or payment of any
dividend on, or other distribution (whether in cash, stock or property) in
respect of, any of Compaq's or any of its Subsidiaries' capital stock, or any
purchase, redemption or other acquisition by Compaq or any of its Subsidiaries
of any of Compaq's capital stock or any other securities of Compaq or its
Subsidiaries or any options, warrants, calls or rights to acquire any such
shares or other securities except for (A) repurchases from Employees following
their termination pursuant to the terms of their pre-existing stock option or
purchase agreements, or (B) the Compaq Rights Dividend, or (iii) any split,
combination or reclassification of any of Compaq's or any of its Subsidiaries'
capital stock.

   2.6 Taxes.  For the purposes of this Agreement, the term "Tax" or,
collectively, "Taxes," shall mean any and all federal, state, local and foreign
taxes, assessments and other governmental charges, duties, impositions and
liabilities, including taxes based upon or measured by gross receipts, income,
profits, sales, use and occupation, and value added, ad valorem, transfer,
franchise, withholding, payroll, recapture, employment, excise and property
taxes, together with all interest, penalties and additions imposed with respect
to such amounts, and any obligations with respect to such amounts arising as a
result of being a member of an affiliated, consolidated, combined or unitary
group for any period or under any agreements or arrangements with any other
Person and including any liability for taxes of a predecessor entity. Compaq
and each of its Subsidiaries have filed all material federal, state, local and
foreign returns, estimates, information statements and reports relating to
Taxes ("Tax Returns") required to be filed by any of them and have paid, or
have adequately reserved (in accordance with GAAP) for the payment of, all
Taxes required to be paid (whether or not shown on any Tax Returns), and the
most recent financial statements contained in the Compaq SEC Reports reflect an
adequate reserve (in accordance with GAAP) for all Taxes payable by Compaq and
its Subsidiaries through the date of such financial statements. No material
deficiencies for any Taxes have been asserted or assessed, or, to the Knowledge
(as defined in Section 8.3(b)) of Compaq, proposed, against Compaq or any of
its Subsidiaries that are not subject to adequate reserves (in accordance with
GAAP). No audit or other examination of any Tax Return of Compaq or any of its
Subsidiaries is presently in progress, nor has Compaq or any of its
Subsidiaries been notified of any request for such an audit or other
examination. Neither Compaq nor any of its Subsidiaries has taken any action or
knows of any fact, agreement or plan or other circumstance that is reasonably
likely to prevent the Merger from qualifying as a reorganization within the
meaning of Section 368(a) of the Code.

   2.7 Intellectual Property.

   (a) No Infringement.  To the Knowledge as of the date hereof of Compaq, the
products, services and operations of Compaq do not infringe or misappropriate
the Intellectual Property (as defined below) of any third party where such
infringement or misappropriation, individually or in the aggregate, would be
reasonably expected to have a material adverse effect on any material division
or business unit or other material operating group of product or service
offerings of Compaq or otherwise have a Material Adverse Effect on Compaq.
"Intellectual Property" shall mean any or all of the following and all rights
in, arising out of, or associated therewith: (i) all United States,
international and foreign patents and applications therefor and all reissues,
divisions, renewals, extensions, provisionals, continuations and
continuations-in-part thereof, (ii) all inventions (whether patentable or not),
invention disclosures, improvements, trade secrets, proprietary information,
know how, technology, technical data and customer lists, and all documentation
relating to any of the foregoing, (iii) all copyrights, copyrights
registrations and applications therefor, and all other rights corresponding
thereto throughout the world, (iv) all industrial designs and any registrations
and applications therefor throughout the world, (v) all mask works and any
registrations and applications therefor throughout the world, (vi) all trade
names, logos, URLs, common law trademarks and service marks, trademark and
service mark registrations and

                                     A-10



applications therefor throughout the world, (vii) all databases and data
collections and all rights therein throughout the world, (viii) all moral and
economic rights of authors and inventors, however denominated, throughout the
world, and (ix) any similar or equivalent rights to any of the foregoing
anywhere in the world.

   (b) No Impairment.  The Merger (including the assignment by operation of law
of any Contract to the Surviving Corporation) will not result in: (i) HP or any
Subsidiary of HP (other than Compaq and its Subsidiaries, but only to the
extent existing prior to the Merger) being bound by any material non-compete or
other material restriction on the operation of any business of HP or its
Subsidiaries, (ii) HP or any Subsidiary of HP (other than Compaq and its
Subsidiaries, but only to the extent existing prior to the Merger) granting any
rights or licenses to any material Intellectual Property of HP or any
Subsidiary of HP to any third party (including a covenant not to sue with
respect to any material Intellectual Property of HP or any Subsidiary of HP),
or (iii) the termination or breach of any Contract to which Compaq is a party,
which termination or breach would reasonably be expected to have a material
adverse effect on any material division or business unit or other material
operating group of product or service offerings of the Surviving Corporation or
HP or otherwise have a Material Adverse Effect on either of them.

   2.8 Compliance; Permits.

   (a) Compliance.  Neither Compaq nor any of its Subsidiaries is, in any
material respect, in conflict with, or in default or in violation of any Legal
Requirement applicable to Compaq or any of its Subsidiaries or by which Compaq
or any of its Subsidiaries or any of their respective businesses or properties
is, or Compaq believes is reasonably likely to be, bound or affected, except,
in each case, or in the aggregate, for conflicts, violations and defaults that
would not have a Material Adverse Effect on Compaq. As of the date hereof, no
material investigation or review by any Governmental Entity is pending or, to
the Knowledge of Compaq, has been threatened in a writing delivered to Compaq
or any of its Subsidiaries, against Compaq or any of its Subsidiaries. There is
no material judgment, injunction, order or decree binding upon Compaq or any of
its Subsidiaries which has or would reasonably be expected to have the effect
of prohibiting or materially impairing any material business practice of Compaq
or any of its Subsidiaries, any acquisition of material property by Compaq or
any of its Subsidiaries or the conduct of business by Compaq and its
Subsidiaries as currently conducted.

   (b) Permits.  Compaq and its Subsidiaries hold, to the extent legally
required, all permits, licenses, variances, exemptions, orders and approvals
from Governmental Entities ("Permits") that are required for the operation of
the business of Compaq, as currently conducted, the failure to hold which would
reasonably be expected to have a Material Adverse Effect on Compaq
(collectively, "Compaq Permits"). As of the date hereof, no suspension or
cancellation of any of the Compaq Permits is pending or, to the Knowledge of
Compaq, threatened. Compaq and its Subsidiaries are in compliance in all
material respects with the terms of the Compaq Permits.

   2.9 Litigation.  As of the date hereof, there are no claims, suits, actions
or proceedings pending or, to the Knowledge of Compaq, overtly threatened
against Compaq or any of its Subsidiaries, before any court, governmental
department, commission, agency, instrumentality or authority, or any arbitrator
that seeks to restrain or enjoin the consummation of the transactions
contemplated hereby or which would reasonably be expected, either singularly or
in the aggregate with all such claims, actions or proceedings, to be material
to the Compaq.

   2.10 Brokers' and Finders' Fees.  Except for fees payable to Salomon Smith
Barney pursuant to an engagement letter dated July 19, 2001, a copy of which
has been provided to HP, Compaq has not incurred, nor will it incur, directly
or indirectly, any liability for brokerage or finders' fees or agents'
commissions or any similar charges in connection with this Agreement or any
transaction contemplated hereby.

   2.11 Transactions with Affiliates.  Except as set forth in the Compaq SEC
Reports, since the date of the Compaq's last proxy statement filed with the
SEC, no event has occurred as of the date hereof that would be

                                     A-11



required to be reported by Compaq pursuant to Item 404 of Regulation S-K
promulgated by the SEC (substituting, for the purposes of this representation
and warranty, each appearance of $60,000 in Item 404 with $500,000). Section
2.11 of the Compaq Disclosure Letter identifies each Person who is an
"affiliate" (as that term is used in Rule 145 promulgated under the Securities
Act) of Compaq as of the date hereof.

   2.12 Employee Benefit Plans.

   (a) Documents.  Section 2.12(a) of the Compaq Disclosure Letter sets forth a
list of the following: (i) all severance and employment agreements of Compaq
with directors or executive officers, (ii) all material severance programs and
policies of each of Compaq or its Subsidiaries, (iii) all plans or agreement of
Compaq or its Subsidiaries relating to any of its current or former employees,
consultants or directors (each, an "Employee") pursuant to which benefits would
vest or an amount would become payable or the terms of which would otherwise be
altered, in any case by virtue of the transactions contemplated hereby (whether
alone or upon the occurrence of any additional or subsequent events), (iv) each
document embodying each Retirement Plan (as defined in Section 2.12(c)) of
Compaq (a "Compaq Retirement Plan"), (v) each Compaq Purchase Plan, and (vi)
each stock option plan, stock award plan, stock appreciation right plan,
phantom stock plan, stock option, other equity or equity-based compensation
plan, equity or other equity based award to any Person (whether payable in
cash, shares or otherwise) (to the extent not issued pursuant to any of the
foregoing plans) or other plan or Contract of any nature with any Person
(whether or not an Employee) pursuant to which any stock, option, warrant or
other right to purchase or acquire capital stock of Compaq or right to payment
based on the value of Compaq capital stock has been granted or otherwise
issued, but, in any case excluding the Compaq Purchase Plans (collectively,
"Compaq Stock Option Plans"). Compaq has delivered or made available to HP for
review each of the items listed on Section 2.12(a) of the Compaq Disclosure
Letter and a current actuarial valuation and/or audited statement of assets and
liabilities for each Compaq Retirement Plan. Section 2.12(a) of the Compaq
Disclosure Letter also identifies whether each Compaq Stock Option Plan (A) is
a "broadly-based" plan, as defined in Section 312.04(h) of the NYSE Listed
Company Manual or (B) has been approved by Compaq's stockholders (plans which
are either "broadly-based" plans or approved by Compaq's stockholders (as
identified on Section 2.12(a) of the Compaq Disclosure Letter) are referred to
herein as "Compaq Broad Plans").

   (b) Benefit Plan Compliance.

   (i) With respect to each material collective bargaining agreement, bonus,
pension, profit sharing, deferred compensation, incentive compensation, stock
ownership, stock purchase, stock option, phantom stock, stock-related or
performance award, retirement, vacation, severance, disability, death benefit,
hospitalization, medical, loan (other than travel allowances and relocation
packages), fringe benefit, disability, sabbatical and other plan, arrangement
or understanding providing benefits to any Employee, employment agreement,
consulting agreement or severance agreement with any current or former officer
or director of Compaq or its Subsidiaries, or any material employment
agreement, consulting agreement or severance agreement for any Employee
(collectively, "Benefit Plans") of Compaq or any of its Subsidiaries ("Compaq
Benefit Plans"), no material event has occurred and there exists no material
condition or set of circumstances, in connection with which Compaq or any of
its Subsidiaries would be subject to any material liability under the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), the Code or any
other applicable Legal Requirement.

   (ii) Each Compaq Benefit Plan has been, in all material respects,
administered and operated in accordance with its terms, with the applicable
provisions of ERISA, the Code and all other applicable material Legal
Requirements and the terms of all applicable collective bargaining agreements.
Each Compaq Benefit Plan, including any material amendments thereto, that is
capable of approval by, and/or registration for and/or qualification for
special tax status with, the appropriate taxation, social security and/or
supervisory authorities in the relevant country, state, territory or the like
(each, an "Approval") has received such Approval or there remains a period of
time in which to obtain such Approval retroactive to the date of any material
amendment that has not previously received such Approval.

                                     A-12



   (iii) To the Knowledge of Compaq, no material oral or written representation
or commitment with respect to any material aspect of any Compaq Benefit Plan
has been made to an Employee of Compaq or any of its Subsidiaries by an
authorized Compaq Employee that is not materially in accordance with the
written or otherwise preexisting terms and provisions of such Compaq Benefit
Plans. To the Knowledge of Compaq, neither Compaq nor any of its Subsidiaries
has entered into any agreement, arrangement or understanding, whether written
or oral, with any trade union, works council or other Employee representative
body or any material number or category of its Employees which would prevent,
restrict or materially impede the implementation of any lay-off, redundancy,
severance or similar program within its or their respective workforces (or any
part of them).

   (iv) There are no material unresolved claims or disputes under the terms of,
or in connection with, any Compaq Benefit Plan (other than routine undisputed
claims for benefits), and no action, legal or otherwise, has been commenced
with respect to any material claim.

   (c) Retirement Plan Funding.  The latest actuarial valuation of each Funded
Retirement Plan (as defined below) of Compaq or its Subsidiaries discloses
that, as of the effective date of the valuation, the aggregate value of the
assets of such Funded Retirement Plan is equal to or greater than the aggregate
value of its liabilities assessed on an ongoing and terminated basis and
calculated in accordance with the actuarial methods and assumptions used in
such valuation pursuant to such Funded Retirement Plan and applicable Legal
Requirements and GAAP. In respect of each Retirement Plan of Compaq or its
Subsidiaries that is not a Funded Retirement Plan, Compaq or its Subsidiaries
have made adequate provision for accrued liabilities in accordance with
applicable Legal Requirements.  For purposes of this Agreement, "Retirement
Plan" shall mean a material arrangement for the provision of Retirement Benefit
Rights (as defined below) to Employees (and, if applicable, beneficiaries
thereof). For purposes of this Agreement, "Retirement Benefit Rights" shall
mean, with respect to an entity, any pension, lump sum, gratuity, or a like
benefit provided or generally intended to be provided on retirement or on death
in respect of an Employee's relationship as a service provider to an entity or
its Subsidiaries. Material post-retirement health benefits and any other
self-insured health benefit arrangements are deemed to be "Retirement Benefit
Rights." Material deferred compensation payments required to be made to an
Employee in respect of the termination of employment are also deemed to be
"Retirement Benefit Rights." "Funded Retirement Plan" means, with respect to
party, a Retirement Plan under which the assets to satisfy the benefit
obligations are legally segregated from the general assets of such party or its
Subsidiaries and are not subject to the creditors of such party or its
Subsidiaries.

   (d) Multiple Employer and Multiemployer Plans.  At no time has Compaq or any
other person or entity under common control within the meaning of Section
414(b), (c), (m) or (o) of the Code (a "Controlled Group Affiliate") with
Compaq participated in and/or been obligated to contribute to any Compaq
Benefit Plan in which any persons which are not or were not at the relevant
time, Controlled Group Affiliates of Compaq and/or their Employees, have
participated. No Compaq Benefit Plan is a "multiemployer plan" within the
meaning of Section 3(37) of ERISA.

   (e) Continuation Coverage.  No Compaq Benefit Plan provides health benefits
(whether or not insured), with respect to Employees after retirement or other
termination of service (other than coverage mandated by applicable Legal
Requirements or benefits, the full cost of which is borne by the Employee)
other than individual arrangements the amounts of which are not material.

   (f) Effect of Transaction.  The execution of this Agreement and the
consummation of the transactions contemplated hereby will not (either alone or
upon the occurrence of any additional or subsequent events) constitute an event
under any Compaq Benefit Plan that will or may result in any material payment
(whether of severance pay or otherwise), acceleration of payment, forgiveness
of indebtedness, vesting, distribution, increase in benefits or obligation to
fund benefits with respect to any Employee. There is no contract, agreement,
plan or arrangement with an Employee to which Compaq or any of its Subsidiaries
is a party as of the date of this Agreement, that, individually or collectively
and as a result of the transaction contemplated hereby (whether

                                     A-13



alone or upon the occurrence of any additional or subsequent events), would
reasonably be expected to give rise to the payment of any amount that would not
be deductible pursuant to Section 280G of the Code.

   (g) Labor.  No collective bargaining agreement is being negotiated or
renegotiated in any material respect by Compaq or any of its Subsidiaries. As
of the date of this Agreement, there is no material labor dispute, strike or
work stoppage against Compaq or any of its Subsidiaries pending or, to the
Knowledge of Compaq, threatened which may materially interfere with the
respective business activities of Compaq or any of its Subsidiaries. As of the
date of this Agreement, to the Knowledge of Compaq, none of Compaq, any of its
Subsidiaries or any of their respective representatives or Employees has
committed any material unfair labor practice in connection with the operation
of the respective businesses of Compaq or any of its Subsidiaries, and there is
no material charge or complaint against Compaq or any of its Subsidiaries by
the National Labor Relations Board or any comparable governmental agency
pending or threatened in writing.

   2.13 Environmental Matters.

   (a) Hazardous Material.  Except as would not result in a Material Adverse
Effect on Compaq, no underground storage tanks and no amount of any substance
that has been designated by any Governmental Entity or by applicable federal,
state or local law to be radioactive, toxic, hazardous or otherwise a danger to
health or the environment, including PCBs, asbestos, petroleum,
urea-formaldehyde and all substances listed as hazardous substances pursuant to
the Comprehensive Environmental Response, Compensation, and Liability Act of
1980, as amended, or defined as a hazardous waste pursuant to the United States
Resource Conservation and Recovery Act of 1976, as amended, and the regulations
promulgated pursuant to said laws, but excluding office and janitorial
supplies, (a "Hazardous Material") are present, as a result of the actions of
Compaq or any of its Subsidiaries or any affiliate of Compaq, or, to the
Knowledge of Compaq, as a result of any actions of any third party or
otherwise, in, on or under any property, including the land and the
improvements, ground water and surface water thereof, that Compaq or any of its
Subsidiaries has at any time owned, operated, occupied or leased.

   (b) Hazardous Materials Activities.  Except as would not result in a
Material Adverse Effect on Compaq: (i) neither Compaq nor any of its
Subsidiaries has transported, stored, used, manufactured, disposed of, released
or exposed its Employees or others to Hazardous Materials in violation of any
law in effect on or before the Closing Date and (ii) neither Compaq nor any of
its Subsidiaries has disposed of, transported, sold, used, released, exposed
its Employees or others to or manufactured any product containing a Hazardous
Material (collectively, "Hazardous Materials Activities") in violation of any
rule, regulation, treaty or statute promulgated by any Governmental Entity in
effect prior to or as of the date hereof to prohibit, regulate or control
Hazardous Materials or any Hazardous Material Activity.

   2.14 Contracts.

   (a) Material Contracts.  For purposes of this Agreement, "Compaq Material
Contract" shall mean:

      (i) any "material contracts" (as such term is defined in Item 601(b)(10)
   of Regulation S-K of the SEC) with respect to Compaq and its Subsidiaries;

      (ii) any Contract containing any covenant: (A) limiting the right of
   Compaq or its Subsidiaries to engage in any material line of business, make
   use of any material Intellectual Property or compete with any Person in any
   material line of business, (B) granting any exclusive distribution or supply
   rights, or (C) otherwise having an adverse effect on the right of Compaq and
   its Subsidiaries to sell, distribute or manufacture any material products or
   services or to purchase or otherwise obtain any material software,
   components, parts or subassemblies;

      (iii) any Contract, or group of Contracts with a Person (or group of
   affiliated Persons), the termination or breach of which would be reasonably
   expected to have a material adverse effect on any material division

                                     A-14



   or business unit or other material operating group of product or service
   offerings of Compaq or otherwise have a Material Adverse Effect on Compaq;
   and

      (iv) (A) all Contracts with the top two (2) providers (as measured by
   fees paid under such Contracts) pursuant to which Compaq licenses operating
   system software for use in its end-user products, (B) all Contracts with the
   top two (2) providers (as measured by fees paid under such Contracts)
   pursuant to which Compaq purchases microprocessors, (C) all Contracts with
   the top five (5) distributors of Compaq's end-user products (as measured by
   revenues received under such Contracts) pursuant to which Compaq distributes
   its end-user products, and (D) all Contracts with the top five (5)
   third-party manufacturers (as measured by fees paid under such Contracts)
   pursuant to which such Compaq products (or subassemblies thereof) are
   manufactured.

   (b) Schedule.  Section 2.14(b) of the Compaq Disclosure Letter sets forth a
list of all Compaq Material Contracts to which is a party or is bound by as of
the date hereof which are described in Sections 2.14(a)(i) and 2.14(a)(iv)
hereof.

   (c) No Breach.  All Compaq Material Contracts are valid and in full force
and effect except to the extent they have previously expired in accordance with
their terms or if the failure to be in full force and effect, individually or
in the aggregate, would not reasonably be expected to be material to Compaq.
Neither Compaq nor any of its Subsidiaries has violated any provision of, or
committed or failed to perform any act which, with or without notice, lapse of
time or both would constitute a default under the provisions of, any Compaq
Material Contract, except in each case for those violations and defaults which,
individually or in the aggregate, would not reasonably be expected to be
material to Compaq.

   2.15 Disclosure.  None of the information supplied or to be supplied by or
on behalf of Compaq for inclusion or incorporation by reference in the
registration statement on Form S-4 (or similar successor form) to be filed with
the SEC by HP in connection with the issuance of HP Common Stock in the Merger
(including amendments or supplements thereto) (the "Registration Statement")
will, at the time the Registration Statement becomes effective under the
Securities Act, contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
are made, not misleading. None of the information supplied or to be supplied by
or on behalf of Compaq for inclusion or incorporation by reference in the
Prospectus/Proxy Statement to be filed with the SEC as part of the Registration
Statement (the "Prospectus/Proxy Statement"), will, at the time the
Prospectus/Proxy Statement is mailed to the stockholders of Compaq or HP, at
the time of the HP Stockholders' Meeting or Compaq Stockholders' Meeting or as
of the Effective Time, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in the light of the circumstances under which
they are made, not misleading. The Prospectus/Proxy Statement will comply as to

for inclusion or incorporation by reference in the Registration Statement or
the Prospectus/Proxy Statement.

   2.18 Rights Plan.  The Board of Directors of Compaq has approved the Compaq

                                AND MERGER SUB

   HP and Merger Sub represent and warrant to Compaq, subject to the exceptions
specifically disclosed in writing in the disclosure letter supplied by HP and

   (a) Organization; Standing and Power.  HP and each of its Subsidiaries is a
corporation or other organization duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation or
organization, has the requisite power and authority to own, lease and operate
its properties and to carry on its business as now being conducted, except
where the failure to be so organized, existing and in good standing would not
reasonably be expected to have a Material Adverse Effect on HP, and is duly
qualified and in good standing to do business in each jurisdiction in which the
nature of its business or the ownership or leasing of its properties makes such
qualification necessary other than in such jurisdictions where the failure to
so qualify or to be good standing, individually or in the aggregate, would not
reasonably be expected to have a Material Adverse Effect on HP.

   (b) Charter Documents.  HP has delivered or made available to Compaq (i) a
true and correct copy of the Certificate of Incorporation (including any
Certificate of Designations) and Bylaws of HP, each as amended to date
(collectively, the "HP Charter Documents") and (ii) the Subsidiary Charter
Documents of each of its Significant Subsidiaries, and each such instrument is
in full force and effect. HP is not in violation of any of the provisions of
the HP Charter Documents and each Subsidiary is not in violation of its
respective Subsidiary Charter Documents, except in the case of a Subsidiary, as
would not reasonably be expected to have a Material Adverse Effect on HP.

                                     A-17

   3.3 Authority; Non-Contravention; Necessary Consents.

   (a) Authority.  Each of HP and Merger Sub has all requisite corporate power
and authority to enter into this Agreement and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby has been duly authorized
by all necessary corporate action on the part of HP and Merger Sub and no other
corporate proceedings on the part of HP or Merger Sub are necessary to
authorize the execution and delivery of this Agreement or to consummate the
Merger and the other transactions contemplated hereby, subject only to the
approval of the Stock Issuance by HP's stockholders, the approval and adoption
of this Agreement and the approval of the Merger by HP as Merger Sub's sole
stockholder and the and the filing of the Certificate of Merger pursuant to
Delaware Law. The affirmative vote of the holders of a majority of the
outstanding shares of HP Common Stock present in person or by proxy in favor of
the Stock Issuance at a meeting duly called and held for approval of the Stock
Issuance is the only vote of the holders of any class or series of HP capital
stock necessary to approve the Stock Issuance, and no other vote of the holders
of any class or series of HP Capital Stock is necessary to approve and adopt
this Agreement, approve the Merger and consummate the Merger and the other
transactions contemplated hereby. This Agreement has been duly executed and
delivered by HP and Merger Sub and, assuming due execution and delivery by
Compaq, constitutes the valid and binding obligation of HP, enforceable against
HP and Merger Sub in accordance with its terms.

   (b) Non-Contravention.  The execution and delivery of this Agreement by HP
and Merger Sub does not, and performance of this Agreement by HP will not: (i)
conflict with or violate the HP Charter Documents, the certificate of
incorporation or bylaws of Merger Sub or any other Subsidiary Charter Documents
of any Subsidiary of HP, (ii) subject to obtaining the approval and adoption of
this Agreement and the approval of the Stock Issuance by HP's stockholders as
contemplated in Section 5.2 and compliance with the requirements set forth in
Section 3.3(c), conflict with or violate any material Legal Requirement
applicable to HP, Merger Sub or any of HP's other Subsidiaries or by which HP,
Merger Sub or any of HP's other Subsidiaries or any of their respective
properties is bound or affected, or (iii) result in any material breach of or
constitute a material default (or an event that with notice or lapse of time or
both would become a material default) under, or impair HP's rights or alter the
rights or obligations of any third party under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of a material Lien on any of the material properties or assets of HP
or any of its Subsidiaries pursuant to, any HP Material Contract (as defined in
Section 3.13). Section 3.3(b) of the HP Disclosure Letter lists all consents,
waivers and approvals under any of HP's or any of its Subsidiaries' Contracts
required to be obtained in connection with the consummation of the transactions
contemplated hereby, which, if individually or in the aggregate not obtained,
would result in a Material Adverse Effect on HP or the Surviving Corporation.

   (c) Necessary Consents.  No consent, approval, order or authorization of, or
registration, declaration or filing with any Governmental Entity is required to
be obtained or made by HP in connection with the execution and delivery of this
Agreement or the consummation of the Merger and other transactions contemplated
hereby,

                                     A-18



except for (i) the Necessary Consents and (ii) such other consents,
authorizations, filings, approvals and registrations which if not obtained or
made would not be material to HP, Merger Sub or Compaq or materially adversely
affect the ability of the parties hereto to consummate the Merger within the
time frame in which the Merger would otherwise be consummated in the absence of
the need for such consent, approval, order, authorization, registration,
declaration or filings.

   3.4 SEC Filings; Financial Statements.

   (a) SEC Filings.  HP has filed all required registration statements,
prospectuses, reports, schedules, forms, statements and other documents
(including exhibits and all other information incorporated by reference)
required to be filed by it with the SEC since January 1, 1998. HP has made
available to Compaq all such registration statements, prospectuses, reports,
schedules, forms, statements and other documents in the form filed with the
SEC. All such required registration statements, prospectuses, reports,
schedules, forms, statements and other documents (including those that HP may
file subsequent to the date hereof), as amended, are referred to herein as the
"HP SEC Reports." As of their respective dates, the HP SEC Reports (i) were
prepared in accordance and complied in all material respects with the
requirements of the Securities Act, or the Exchange Act, as the case may be,
and the rules and regulations of the SEC thereunder applicable to such HP SEC
Reports and (ii) did not at the time they were filed contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, except
to the extent corrected prior to the date hereof by a subsequently filed HP SEC
Report. None of HP's Subsidiaries is required to file any forms, reports or
other documents with the SEC.

   (b) Financial Statements.  Each of the consolidated financial statements
(including, in each case, any related notes thereto) contained in the HP SEC
Reports (the "HP Financials"), including each HP SEC Report filed after the
date hereof until the Closing: (i) complied as to form in all material respects
with the published rules and regulations of the SEC with respect thereto, (ii)
was prepared in accordance with GAAP applied on a consistent basis throughout
the periods involved (except as may be indicated in the notes thereto or, in
the case of unaudited interim financial statements, as may be permitted by the
SEC on Form 10-Q, 8-K or any successor form under the Exchange Act), and (iii)
fairly presented in all material respects the consolidated financial position
of HP and its consolidated Subsidiaries as at the respective dates thereof and
the consolidated results of HP's operations and cash flows for the periods
indicated. The balance sheet of HP contained in the HP SEC Reports as of
October 31, 2000 is hereinafter referred to as the "HP Balance Sheet." Except
as disclosed in the HP Financials, since the date of the HP Balance Sheet and
through the date hereof, neither HP nor any of its Subsidiaries has any
liabilities required under GAAP to be set forth on a consolidated balance sheet
(absolute, accrued, contingent or otherwise) which, individually or in the
aggregate, would be reasonably expected to have a Material Adverse Effect on
HP, except for liabilities incurred since the date of the HP Balance Sheet in
the ordinary course of business consistent with past practices and liabilities
incurred pursuant to this Agreement.

   3.5 Absence of Certain Changes or Events.  Since the date of the HP Balance
Sheet and through the date hereof there has not been: (i) any Material Adverse
Effect on HP, (ii) any declaration, setting aside or payment of any dividend
on, or other distribution (whether in cash, stock or property) in respect of,
any of HP's or any of its Subsidiaries' capital stock, or any purchase,
redemption or other acquisition by HP or any of its Subsidiaries of any of HP's
capital stock or any other securities of HP or its Subsidiaries or any options,
warrants, calls or rights to acquire any such shares or other securities except
for (A) repurchases from Employees following their termination pursuant to the
terms of their pre-existing stock option or purchase agreements or (B)
repurchases pursuant to HP's public stock repurchase programs existing as of
July 31, 2001, or (C) the HP Rights Dividend, or (iii) any split, combination
or reclassification of any of HP's or any of its Subsidiaries' capital stock.

   3.6 Taxes.  HP and each of its Subsidiaries have filed all material Tax
Returns required to be filed by any of them and have paid, or have adequately
reserved (in accordance with GAAP) for the payment of, all Taxes required to be
paid (whether or not shown on any Tax Returns), and the most recent financial
statements

                                     A-19



contained in the HP SEC Reports reflect an adequate reserve (in accordance with
GAAP) for all Taxes payable by HP and its Subsidiaries through the date of such
financial statements. No material deficiencies for any Taxes have been asserted
or assessed, or to the Knowledge of HP, proposed, against HP or any of its
Subsidiaries that are not subject to adequate reserves (in accordance with
GAAP). Neither the HP nor any of its Subsidiaries has taken any action or knows
of any fact, agreement or plan or other circumstance that is reasonably likely
to prevent the Merger from qualifying as a reorganization within the meaning of
Section 368(a) of the Code.

   3.7 Intellectual Property.

   (a) No Infringement.  To the Knowledge as of the date hereof of HP, the
products, services and operations of HP do not infringe or misappropriate the
Intellectual Property of any third party where such infringement or
misappropriation, individually or in the aggregate, would be reasonably
expected to have a material adverse effect on any material division or business
unit or other material operating group of product or service offerings of HP or
otherwise have a Material Adverse Effect on HP.

   (b) No Impairment.  The Merger will not result in the termination or breach
of any Contract to which HP is a party, which termination or breach would
reasonably be expected to have a material adverse effect on any material
division or business unit or other material operating group of product or
service offerings of HP or otherwise have a Material Adverse Effect on HP.

   3.8 Compliance; Permits.

   (a) Compliance.  Neither HP nor any of its Subsidiaries is, in any material
respect, in conflict with, or in default or in violation of any Legal
Requirement applicable to HP or any of its Subsidiaries or by which HP or any
of its Subsidiaries or any of their respective businesses or properties is, or
HP believes is reasonably likely to be, bound or affected, except, in each
case, or in the aggregate, for conflicts, violations and defaults that would
not have a Material Adverse Effect on HP. As of the date hereof, no material
investigation or review by any Governmental Entity is pending or, to the
Knowledge of HP, has been threatened in a writing delivered to HP or any of its
Subsidiaries, against HP or any of its Subsidiaries. There is no material
judgment, injunction, order or decree binding upon HP or any of its
Subsidiaries which has or would reasonably be expected to have the effect of
prohibiting or materially impairing any material business practice of HP or any
of its Subsidiaries, any acquisition of material property by HP or any of its
Subsidiaries or the conduct of business by HP and its Subsidiaries as currently
conducted.

   (b) Permits.  HP and its Subsidiaries hold, to the extent legally required,
all Permits that required for the operation of the business of HP, as currently
conducted, the failure to hold which would reasonably be expected to have a
Material Adverse Effect on HP (collectively, "HP Permits"). As of the date
hereof, no suspension or cancellation of any of the HP Permits is pending or,
to the Knowledge of HP, threatened. HP and its Subsidiaries are in compliance
in all material respects with the terms of the HP Permits.

   3.9 Litigation.  As of the date hereof, there are no claims, suits, actions
or proceedings pending or, to the Knowledge of HP, overtly threatened against
HP or any of its Subsidiaries, before any court, governmental department,
commission, agency, instrumentality or authority, or any arbitrator that seeks
to restrain or enjoin the consummation of the transactions contemplated hereby
or which would reasonably be expected, either singularly or in the aggregate
with all such claims, actions or proceedings, to be material to HP.

   3.10 Brokers' and Finders' Fees.  Except for fees payable to Goldman, Sachs
& Co. pursuant to an engagement letter dated July 25, 2001, a copy of which has
been provided to Compaq, HP has not incurred, nor will it incur, directly or
indirectly, any liability for brokerage or finders' fees or agents' commissions
or any similar charges in connection with this Agreement or any transaction
contemplated hereby.

                                     A-20



   3.11 Employee Benefit Plans.

   (a) Benefit Plan Compliance.

      (i) With respect to the Benefit Plan of HP or any of its Subsidiaries
   ("HP Benefit Plan"), no material event has occurred and there exists no
   material condition or set of circumstances, in connection with which HP or
   any of its Subsidiaries would be subject to any material liability under the
   ERISA, the Code or any other applicable Legal Requirement.

      (ii) Each HP Benefit Plan has been, in all material respects,
   administered and operated in accordance with its terms, with the applicable
   provisions of ERISA, the Code and all other applicable material Legal
   Requirements and the terms of all applicable collective bargaining
   agreements. Each HP Benefit Plan, including any material amendments thereto,
   that is capable of Approval has received such Approval or there remains a
   period of time in which to obtain such Approval retroactive to the date of
   any material amendment that has not previously received such Approval.

      (iii) To the Knowledge of HP, no material oral or written representation
   or commitment with respect to any material aspect of any HP Benefit Plan has
   been made to an Employee of HP or any of its Subsidiaries by an authorized
   HP Employee that is not materially in accordance with the written or
   otherwise preexisting terms and provisions of such HP Benefit Plans. To the
   Knowledge of HP, neither HP nor any of its Subsidiaries has entered into any
   agreement, arrangement or understanding, whether written or oral, with any
   trade union, works council or other Employee representative body or any
   material number or category of its Employees which would prevent, restrict
   or materially impede the implementation of any lay-off, redundancy,
   severance or similar program within its or their respective workforces (or
   any part of them).

      (iv) There are no material unresolved claims or disputes under the terms
   of, or in connection with, any HP Benefit Plan (other than routine
   undisputed claims for benefits), and no action, legal or otherwise, has been
   commenced with respect to any material claim.

   (b) Retirement Plan Funding.  The latest actuarial valuation of each Funded
Retirement Plan of HP or its Subsidiaries discloses that, as of the effective
date of the valuation, the aggregate value of the assets of such Funded
Retirement Plan is equal to or greater than the aggregate value of its
liabilities assessed on an ongoing and terminated basis and calculated in
accordance with the actuarial methods and assumptions used in such valuation
pursuant to such Funded Retirement Plan and applicable Legal Requirements and
GAAP. In respect of each Retirement Plan of HP or its Subsidiaries that is not
a Funded Retirement Plan, HP or its Subsidiaries have made adequate provision
for accrued liabilities in accordance with applicable Legal Requirements.

   (c) Multiple Employer and Multiemployer Plans.  At no time has HP or
Controlled Group Affiliate with HP participated in and/or been obligated to
contribute to any HP Benefit Plan in which any persons which are not or were
not at the relevant time, Controlled Group Affiliates of HP and/or their
Employees, have participated. No HP Benefit Plan is a "multiemployer plan"
within the meaning of Section 3(37) of ERISA.

   (d) Continuation Coverage.  No HP Benefit Plan provides health benefits
(whether or not insured), with respect to Employees after retirement or other
termination of service (other than coverage mandated by applicable Legal
Requirements or benefits, the full cost of which is borne by the Employee)
other than individual arrangements the amounts of which are not material.

   (e) Effect of Transaction.  The execution of this Agreement and the
consummation of the transactions contemplated hereby will not (either alone or
upon the occurrence of any additional or subsequent events) constitute an event
under any HP Benefit Plan that will or may result in any material payment
(whether of severance pay or otherwise), acceleration of payment, forgiveness
of indebtedness, vesting, distribution, increase in benefits or obligation to
fund benefits with respect to any Employee. There is no contract, agreement,
plan or arrangement with an Employee to which HP or any of its Subsidiaries is
a party as of the date of this Agreement, that, individually or collectively
and as a result of the transaction contemplated hereby (whether alone or upon

                                     A-21



the occurrence of any additional or subsequent events), would reasonably be
expected to give rise to the payment of any amount that would not be deductible
pursuant to Section 280G of the Code.

   (f) Labor.  No collective bargaining agreement is being negotiated or
renegotiated in any material respect by HP or any of its Subsidiaries. As of
the date of this Agreement, there is no material labor dispute, strike or work
stoppage against HP or any of its Subsidiaries pending or, to the Knowledge of
HP, threatened which may materially interfere with the respective business
activities of HP or any of its Subsidiaries. As of the date of this Agreement,
to the Knowledge of HP, none of HP, any of its Subsidiaries or any of their
respective representatives or Employees has committed any material unfair labor
practice in connection with the operation of the respective businesses of HP or
any of its Subsidiaries, and there is no material charge or complaint against
HP or any of its Subsidiaries by the National Labor Relations Board or any
comparable governmental agency pending or threatened in writing.

   3.12 Environmental Matters.

   (a) Hazardous Material.  Except as would not result in a Material Adverse
Effect on HP, no underground storage tanks and no amount of any Hazardous
Material are present, as a result of the actions of HP or any of its
Subsidiaries or any affiliate of HP, or, to the Knowledge of HP, as a result of
any actions of any third party or otherwise, in, on or under any property,
including the land and the improvements, ground water and surface water
thereof, that HP or any of its Subsidiaries has at any time owned, operated,
occupied or leased.

   (b) Hazardous Materials Activities.  Except as would not result in a
Material Adverse Effect on HP (i) neither HP nor any of its Subsidiaries has
transported, stored, used, manufactured, disposed of, released or exposed its
Employees or others to Hazardous Materials in violation of any law in effect on
or before the Closing Date and (ii) neither HP nor any of its Subsidiaries has
engaged in any Hazardous Materials Activities in violation of any rule,
regulation, treaty or statute promulgated by any Governmental Entity in effect
prior to or as of the date hereof to prohibit, regulate or control Hazardous
Materials or any Hazardous Material Activity.

   3.13 Contracts.  All HP Material Contracts (as defined below) are valid and
in full force and effect except to the extent they have previously expired in
accordance with their terms or if the failure to be in full force and effect,
individually or in the aggregate, would not reasonably be expected to be
material to HP. Neither HP nor any of its Subsidiaries has violated any
provision of, or committed or failed to perform any act which, with or without
notice, lapse of time or both would constitute a default under the provisions
of, any HP Material Contract, except in each case for those violations and
defaults which, individually or in the aggregate, would not reasonably be
expected to be material to HP. For purposes of this Agreement, "HP Material
Contract" shall mean any Contract, or group of Contracts, with a Person (or
group of affiliated Persons) the termination or breach of which would be
reasonably expected to have a material adverse effect on any material division
or business unit or other material operating group of product or service
offerings of HP or otherwise have a Material Adverse Effect on HP.

   3.14 Disclosure.  None of the information supplied or to be supplied by or
on behalf of HP or Merger Sub for inclusion or incorporation by reference in
the Registration Statement will, at the time the Registration Statement becomes
effective under the Securities Act, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the
circumstances under which they are made, not misleading. None of the
information supplied or to be supplied by or on behalf of HP and Merger Sub for

favor of, in the case of HP, the Stock Issuance, and, in the case of Compaq,
adoption and approval of this Agreement and the Merger.

   5.3 Acquisition Proposals.

   (a) No Solicitation.  Each of HP and Compaq agrees that neither it nor any
of its Subsidiaries nor any of the officers and directors of it or its
Subsidiaries shall, and that it shall use all reasonable efforts to cause its
and its Subsidiaries' Employees, agents and representatives (including any
investment banker, attorney or accountant retained by it or any of its
Subsidiaries) not to (and shall not authorize any of them to) directly or
indirectly: (i) solicit, initiate, encourage, knowingly facilitate or induce
any inquiry with respect to, or the making, submission or announcement of, any
Acquisition Proposal (as defined in Section 5.3(g)) with respect to itself,
(ii) participate in any discussions or negotiations regarding, or furnish to
any Person any nonpublic information with respect to, or take any other action
to facilitate any inquiries or the making of any proposal that constitutes or
may reasonably be expected to lead to, any Acquisition Proposal with respect to
itself, (iii) engage in discussions with any Person with respect to any
Acquisition Proposal with respect to itself, except as to the existence of
these provisions, (iv) approve, endorse or recommend any Acquisition Proposal
with respect to itself (except to the extent specifically permitted pursuant to

any contract agreement or commitment contemplating or otherwise relating to any
Acquisition Proposal or transaction contemplated thereby with respect to
itself. HP and Compaq, as the case may be, and their respective Subsidiaries
will each immediately cease any and all existing activities, discussions or
negotiations with any third parties conducted heretofore with respect to any
Acquisition Proposal with respect to itself.

   (b) Notification of Unsolicited Acquisition Proposals.

      (i) As promptly as practicable after receipt of any Acquisition Proposal
   or any request for nonpublic information or inquiry which it reasonably
   believes would lead to an Acquisition Proposal, HP or Compaq, as the case
   may be, shall provide the other party hereto with oral and written notice of
   the material terms and conditions of such Acquisition Proposal, request or
   inquiry, and the identity of the Person or group making any such Acquisition
   Proposal, request or inquiry and a copy of all written materials provided in
   connection with such Acquisition Proposal, request or inquiry. The recipient
   of the Acquisition Proposal, request or inquiry shall provide the other
   party hereto as promptly as practicable oral and written notice setting
   forth all such information as is reasonably necessary to keep the other
   party informed in all material

                                     A-29



   respects of the status and details (including material amendments or
   proposed material amendments) of any such Acquisition Proposal, request or
   inquiry and shall promptly provide to the other party hereto a copy of all
   written materials subsequently provided in connection with such Acquisition
   Proposal, request or inquiry.

      (ii) HP or Compaq, as the case may be, shall provide the other party
   hereto with forty-eight (48) hours prior notice (or such lesser prior notice
   as is provided to the members of its Board of Directors) of any meeting of
   the its Board of Directors at which its Board of Directors is reasonably
   expected to consider any Acquisition Proposal.

   (c) Superior Offers.  Notwithstanding anything to the contrary contained in
Section 5.3(a), in the event that HP or Compaq, as the case may be, receives an
unsolicited, bona fide written Acquisition Proposal with respect to itself from
a third party that its Board of Directors has in good faith concluded
(following the receipt of the advice of its outside legal counsel and its
financial advisor), is, or is reasonably likely to result in, a Superior Offer
(as defined in Section 5.3(g)), it may then take the following actions (but
only if and to the extent that its Board of Directors concludes in good faith,
following the receipt of advice of its outside legal counsel, that the failure
to do so is reasonably likely to result in a breach of its fiduciary
obligations under applicable law):

      (i) Furnish nonpublic information to the third party making such
   Acquisition Proposal, provided that (A) (1) concurrently with furnishing any
   such nonpublic information to such party, it gives the other party hereto
   written notice of its intention to furnish nonpublic information and (2) it
   receives from the third party an executed confidentiality agreement
   containing customary limitations on the use and disclosure of all nonpublic
   written and oral information furnished to such third party on its behalf,
   the terms of which are at least as restrictive as the terms contained in the
   Confidentiality Agreement (as defined in Section 5.4) and (B)
   contemporaneously with furnishing any such nonpublic information to such
   third party, it furnishes such nonpublic information to the other party
   hereto (to the extent such nonpublic information has not been previously so
   furnished); and

      (ii) Engage in negotiations with the third party with respect to the
   Acquisition Proposal, provided that concurrently with entering into
   negotiations with such third party, it gives the other party hereto written
   notice of the its intention to enter into negotiations with such third party.

   (d) Changes of Recommendation.  In response to the receipt of a Superior
Offer, the Board of Directors of HP or Compaq, as the case may be, may
withhold, withdraw, amend or modify its recommendation in favor of the Merger,
and, in the case of a Superior Offer that is a tender or exchange offer made
directly to its stockholders, may recommend that its stockholders accept the
tender or exchange offer (any of the foregoing actions, whether by a Board of
Directors or a committee thereof, a "Change of Recommendation"), if all of the
following conditions in clauses (i) through (v) are met:

      (i) A Superior Offer with respect to it has been made and has not been
   withdrawn;

      (ii) Its Stockholders' Meeting has not occurred;

      (iii) It shall have (A) provided to the other party hereto written notice
   which shall state expressly (1) that it has received a Superior Offer, (2)
   the material terms and conditions of the Superior Offer and the identity of
   the Person or group making the Superior Offer, and (3) that it intends to
   effect a Change of Recommendation and the manner in which it intends to do
   so, (B) provided to the other party hereto a copy of all written materials
   delivered to the Person or group making the Superior Offer in connection
   with such Superior Offer, and (C) made available to the other party hereto
   all materials and information made available to the Person or group making
   the Superior Offer in connection with such Superior Offer;

      (iv) Its Board of Directors has concluded in good faith, after receipt of
   advice of its outside legal counsel, that, in light of such Superior Offer,
   the failure of the Board of Directors to effect a Change of Recommendation
   is reasonably likely to result in a breach of its fiduciary obligations to
   its stockholders under applicable law; and

                                     A-30



      (v) It shall not have breached in any material respect any of the
   provisions set forth in Section 5.2 or this Section 5.3.

   (e) Continuing Obligation to Call, Hold and Convene Stockholders' Meeting;
No Other Vote.  Notwithstanding anything to the contrary contained in this
Agreement, the obligation of HP or Compaq, as the case may be, to call, give
notice of, convene and hold its Stockholders' Meeting shall not be limited or
otherwise affected by the commencement, disclosure, announcement or submission
to it of any Acquisition Proposal with respect to it, or by any Change of
Recommendation. Neither HP nor Compaq shall submit to the vote of its
respective stockholders any Acquisition Proposal, or propose to do so.

   (f) Compliance with Tender Offer Rules.  Nothing contained in this Agreement
shall prohibit either party or its respective Board of Directors from taking
and disclosing to its stockholders a position contemplated by Rules 14d-9 and
14e-2(a) promulgated under the Exchange Act; provided that the content of any
such disclosure thereunder shall be governed by the terms of this Agreement.
Without limiting the foregoing proviso, neither party shall effect a Change of
Recommendation unless specifically permitted pursuant to the terms of
Section 5.3(d).

   (g) Certain Definitions.  For purposes of this Agreement, the following
terms shall have the following meanings:

      (i) "Acquisition Proposal," with respect to a party, shall mean any offer
   or proposal, relating to any transaction or series of related transactions
   involving: (A) any purchase from such party or acquisition by any Person or
   "group" (as defined under Section 13(d) of the Exchange Act and the rules
   and regulations thereunder) of more than a ten percent (10%) interest in the
   total outstanding voting securities of such party or any of its Subsidiaries
   or any tender offer or exchange offer that if consummated would result in
   any Person or group beneficially owning ten percent (10%) or more of the
   total outstanding voting securities of such party or any of its Subsidiaries
   or any merger, consolidation, business combination or similar transaction
   involving such party or any of its Subsidiaries, (B) any sale, lease (other
   than in the ordinary course of business), exchange, transfer, license (other
   than in the ordinary course of business), acquisition or disposition of more
   than ten percent (10%) of the assets of such party (including its
   Subsidiaries taken as a whole), or (C) any liquidation or dissolution of
   such party (provided, however, a HP Permitted Acquisition shall not be
   deemed an Acquisition Proposal with respect to HP and a Compaq Permitted
   Acquisition shall not be deemed an Acquisition Proposal with respect to
   Compaq and the transactions contemplated hereby shall not be deemed an
   Acquisition Proposal in any case); and

      (ii) "Superior Offer," with respect to party, shall mean an unsolicited,
   bona fide written offer made by a third party to acquire, directly or
   indirectly, pursuant to a tender offer, exchange offer, merger,
   consolidation or other business combination, all or substantially all of the
   assets of such party or a majority of the total outstanding voting
   securities of such party and as a result of which the stockholders of such
   party immediately preceding such transaction would hold less than fifty
   percent (50%) of the equity interests in the surviving or resulting entity
   of such transaction or any direct or indirect parent or subsidiary thereof,
   on terms that the Board of Directors of such party has in good faith
   concluded (following the receipt of advice of its outside legal counsel and
   its financial adviser), taking into account, among other things, all legal,
   financial, regulatory and other aspects of the offer and the Person making
   the offer, to be more favorable, from a financial point of view, to such
   party's stockholders (in their capacities as stockholders) than the terms of
   the Merger and is reasonably capable of being consummated.

   5.4 Confidentiality; Access to Information; No Modification of
Representations, Warranties or Covenants.

   (a) Confidentiality.  The parties acknowledge that Compaq and HP have
previously executed a Confidentiality Agreement dated June 29, 2001 (the
"Confidentiality Agreement"), which Confidentiality Agreement will continue in

on the other hand, shall, and shall cause each of their respective Subsidiaries
to, furnish promptly to the other party a copy of any report, schedule,
registration statement and other document filed by it during such period
pursuant to the requirements of federal or state securities laws; provided,
however, that any party may restrict the foregoing access to the extent that
any law, treaty, rule or regulation of any Governmental Entity applicable to
such party requires such party or its Subsidiaries to restrict or prohibit
access to any such properties or information.

   (c) No Modification of Representations and Warranties or Covenants.  No
information or knowledge obtained in any investigation or notification pursuant
to this Section 5.4, Section 5.6 or Section 5.7 shall affect or be deemed to
modify any representation or warranty contained herein, the covenants or
agreements of the parties hereto or the conditions to the obligations of the
parties hereto under this Agreement.

   5.5 Public Disclosure.  Without limiting any other provision of this
Agreement, HP and Compaq will consult with each other before issuing, and

and the securities laws of any foreign country, or any other Legal Requirement
relating to the Merger. Each of HP and Compaq will cause all documents that it
is responsible for filing with any Governmental Entity under this Section
5.6(a) to comply in all material respects with all applicable Legal
Requirements.

     (b) Exchange of Information.  HP, Merger Sub and Compaq each shall
promptly supply the other with any information which may be required in order
to effectuate any filings or application pursuant to Section 5.6(a). Except
where prohibited by applicable Legal Requirements, and subject to the
Confidentiality Agreement, each of Compaq and HP shall consult with the other
prior to taking a position with respect to any such filing, shall permit the
other to review and discuss in advance, and consider in good faith the views of
the

                                     A-32



other in connection with any analyses, appearances, presentations, memoranda,
briefs, white papers, arguments, opinions and proposals before making or

provide the other (and its counsel) with copies of all filings, presentations
or submissions (and a summary of any oral presentations) made by such party
with any Governmental Entity in connection with this Agreement or the
transactions contemplated hereby, provided that with respect to any such
filing, presentation or submission, each of HP and Compaq need not supply the
other (or its counsel) with copies (or in case of oral presentations, a
summary) to the extent that any law, treaty, rule or regulation of any
Governmental Entity applicable to such party requires such party or its
Subsidiaries to restrict or prohibit access to any such properties or
information.

     (c) Notification.  Each of HP, Merger Sub and Compaq will notify the other
promptly upon the receipt of: (i) any comments from any officials of any
Governmental Entity in connection with any filings made pursuant hereto and
(ii) any request by any officials of any Governmental Entity for amendments or
supplements to any filings made pursuant to, or information provided to comply
in all material respects with, any Legal Requirements. Whenever any event
occurs that is required to be set forth in an amendment or supplement to any
filing made pursuant to Section 5.6(a), HP, Merger Sub or Compaq, as the case
may be, will promptly inform the other of such occurrence and cooperate in
filing with the applicable Governmental Entity such amendment or supplement.

     (d) Reasonable Efforts.  Subject to the express provisions of Section 5.2
and Section 5.3 hereof and upon the terms and subject to the conditions set
forth herein, each of the parties agrees to use all reasonable efforts to take,
or cause to be taken, all actions, and to do, or cause to be done, and to
assist and cooperate with the other parties in doing, all things necessary,
proper or advisable to consummate and make effective, in the most expeditious

reasonable steps as may be necessary to avoid any suit, claim, action,
investigation or proceeding by any Governmental Entity, (iii) the obtaining of
all necessary consents, approvals or waivers from third parties, including all
Necessary Consents, (iv) the defending of any suits, claims, actions,
investigations or proceedings, whether judicial or administrative, challenging

execution or delivery of any additional instruments necessary to consummate the
transactions contemplated by, and to fully carry out the purposes of, this
Agreement. In connection with and without limiting the foregoing, Compaq and
its Board of Directors shall, if any takeover statute or similar Legal
Requirement is or becomes applicable to the Merger, this Agreement or any of
the transactions contemplated by this Agreement, use all reasonable efforts to
ensure that the Merger and the other transactions contemplated by this
Agreement may be consummated as promptly as practicable on the terms
contemplated by this Agreement and otherwise to minimize the effect of such
Legal Requirement on the Merger, this Agreement and the transactions
contemplated hereby.

   (e) Limitation on Divestiture.  Notwithstanding anything in this Agreement
to the contrary, nothing contained in this Agreement shall be deemed to require
HP or Compaq or any Subsidiary or affiliate thereof to take or agree to take
any Action of Divestiture (as defined below) which would be reasonably likely
materially adversely impact the benefits expected to be derived by HP and its
Subsidiaries (on a combined basis with Compaq and its Subsidiaries) as a result
of the transactions contemplated hereby or would be reasonably likely to
materially adversely affect HP and its Subsidiaries (on a combined basis with
Compaq and its Subsidiaries) following the Merger (a "Restricted Divestiture").
For purposes of this Agreement, an "Action of Divestiture"

                                     A-33



shall mean (i) making proposals, executing or carrying out agreements or
submitting to Legal Requirements providing for the license, sale or other
disposition or holding separate (through the establishment of a trust or
otherwise) of any assets or categories of assets that are material to HP,
Compaq or any of their respective Subsidiaries or the holding separate of
Compaq capital stock or imposing or seeking to impose any limitation on the
ability of HP, Compaq or any of their respective Subsidiaries, to conduct their
respective businesses or own such assets or to acquire, hold or exercise full
rights of ownership of Compaq's business or (ii) otherwise taking any step to
avoid or eliminate any impediment which may be asserted under any Legal
Requirement governing competition, monopolies or restrictive trade practices.

   5.7 Notification of Certain Matters.

   (a) By Compaq.  Compaq shall give prompt notice to HP and Merger Sub of any
representation or warranty made by it contained in this Agreement becoming
untrue or inaccurate, or any failure of Compaq to comply with or satisfy in any
material respect any covenant, condition or agreement to be complied with or
satisfied by it under this Agreement, in each case, such that the conditions
set forth in Section 6.3(a) or 6.3(b) would not be satisfied.

   (b) By HP.  HP and Merger Sub shall give prompt notice to Compaq of any
representation or warranty made by it contained in this Agreement becoming
untrue or inaccurate, or any failure of HP to comply with or satisfy in any
material respect any covenant, condition or agreement to be complied with or
satisfied by it under this Agreement, in each case, such that the conditions
set forth in Section 6.2(a) or 6.2(b) would not be satisfied.

   5.8 Third-Party Consents.  As soon as practicable following the date hereof,
HP and Compaq will each use all reasonable efforts to obtain any material
consents, waivers and approvals under any of its or its Subsidiaries'
respective Contracts required to be obtained in connection with the
consummation of the transactions contemplated hereby.

   5.9 Equity Awards and Employee Benefits.

   (a) Assumption of Stock Options.  At the Effective Time, each then
outstanding Compaq Option (including each Compaq SAR), whether or not
exercisable at the Effective Time and regardless of the respective exercise (or
base) prices thereof, will be assumed by HP. Each Compaq Option so assumed by
HP under this Agreement will continue to have, and be subject to, the same
terms and conditions set forth in the applicable Compaq Option (including any
applicable stock option agreement or other document evidencing such Compaq
Option) immediately prior to the Effective Time (including any repurchase
rights or vesting provisions), except that (i) each Compaq Option will be
exercisable (or will become exercisable in accordance with its terms) for (or
will relate to, in the case of a Compaq SAR)) that number of whole shares of HP
Common Stock equal to the product of the number of shares of Compaq Common
Stock that were issuable upon exercise of such Compaq Option (or, in the case
of Compaq SARs, the number of shares of Compaq Common Stock subject to such
Compaq SAR) immediately prior to the Effective Time multiplied by the Exchange
Ratio, rounded down to the nearest whole number of shares of HP Common Stock
and (ii) the per share exercise price for the shares of HP Common Stock
issuable upon exercise of such assumed Compaq Option (or the base price to
which the assumed Compaq SAR relates) will be equal to the quotient determined
by dividing the exercise price per share of Compaq Common Stock at which such
Compaq Option was exercisable (or the base price subject to the Compaq SAR)
immediately prior to the Effective Time by the Exchange Ratio, rounded up to
the nearest whole cent. Each assumed Compaq Option (including each Compaq SAR)
shall be vested immediately following the Effective Time as to the same
percentage of the total number of shares subject thereto as it was vested as to
immediately prior to the Effective Time, except to the extent such Compaq
Option (or Compaq SAR) by its terms in effect prior to the date hereof provides
for acceleration of vesting. As soon as reasonably practicable, HP will issue
to each Person who holds an assumed Compaq Option (including each Compaq SAR) a
document evidencing the foregoing assumption of such Compaq Option (including
each Compaq SAR) by HP.

                                     A-34



   (b) Incentive Stock Options.  The conversion of Compaq Options provided for
in Section 5.9(a), with respect to any options which are intended to be
"incentive stock options" (as defined in Section 422 of the Code) shall be
effected in a manner consistent with Section 424(a) of the Code.

   (c) Termination of Compaq Employee Stock Purchase Plans.  Prior to the
Effective Time, each of the Compaq Purchase Plans shall be terminated. The
rights of participants in each Compaq Purchase Plan with respect to any
offering period then underway under such Compaq Purchase Plan shall be
determined by treating the last business day prior to, or if more
administratively advisable, the last payroll date of Compaq immediately prior
to, the Effective Time, as the last day of such offering period and by making
such other pro-rata adjustments as may be necessary to reflect the shortened
offering period but otherwise treating such shortened offering period as a
fully effective and completed offering period for all purposes under such
Compaq Purchase Plan. Prior to the Effective Time, Compaq shall take all
actions (including, if appropriate, amending the terms of such Compaq Purchase
Plan that are necessary to give effect to the transactions contemplated by this
Section 5.9(c).

   (d) Employee Compensation.  For a twelve (12) month period following the
Effective Time, HP will use all reasonable efforts to provide generally to
those of its employees and employees of the Surviving Corporation who shall
have been employees of Compaq immediately prior to the Effective Time
("Continuing Employees"), a total compensation (including benefits) package
that, in the aggregate, is generally comparable to the total compensation
(including benefits) package provided to those employees prior to the execution
of this Agreement.

   (e) Service Credit.  Following the Effective Time, HP will use all
reasonable efforts to give each Continuing Employee full credit for prior
service with Compaq or its Subsidiaries for purposes of (i) eligibility and
vesting under any HP Benefit Plan, (ii) determination of benefits levels under
any vacation or severance HP Benefit Plan and (iii) determination of "retiree"
status under any equity compensation HP Benefit Plan, for which the Continuing
Employee is otherwise eligible and in which the Continuing Employee is offered
participation, in each case except where such crediting would (A) result in a
duplication of benefits or (B) otherwise cause HP or its Subsidiaries or any HP
Benefit Plan or trust relating thereto to accrue or pay for benefits that
relate to any time period prior to the Continuing Employee's participation in
the HP Benefit Plan.

   (f) Employee Communications.  With respect to matters described in Section
5.9, Compaq will use all reasonable efforts to consult with HP (and consider in
good faith the advice of HP) prior to sending any notices or other
communication materials to its Employees.

   (g) Plan Documents.  Without limiting the generality of Section 5.4(b), as
promptly as practicable following the date hereof (if practicable, with thirty
(30) days from the date hereof), Compaq shall provide access to HP to copies
of: (i) all documents embodying all Compaq Benefit Plans, (ii) the most recent
annual actuarial valuations and/or audited statement of assets and liabilities
for each Compaq Retirement Plan, if any, for each Compaq Benefit Plan, (iii)
the three (3) most recent annual reports, returns, securities registration
statements or other filings, if any, required to be filed with any Governmental
Entity under applicable Legal Requirement in connection with each Compaq
Benefit Plan, (iv) the most recent Approval for each Compaq Benefit Plan, as
applicable, (v) all material correspondence to or from any Governmental Entity
relating to any Compaq Benefit Plan, (vi) all material communications to
Employees regarding in each case, relating to any amendments, terminations,
establishments, increases or decreases in benefits, acceleration of payments or
vesting schedules or other events which would result in any material liability
under any Compaq Benefit Plan or proposed Compaq Benefit Plan, and (vii) a
summary with respect to each Compaq Option outstanding as of the date of this
Agreement of: (a) the particular Compaq Stock Option Plan (if any) pursuant to
which such Compaq Option was granted, (b) the name and location of the holder
or receipt of such Compaq Option, (c) the number of shares of Compaq Common
Stock subject to such Compaq Option or value covered thereby, (d) the exercise
or base price of such Compaq Option, (e) the date on which such Compaq Option
was granted, (f) the applicable vesting schedule and the extent to which such
Compaq Option is vested and exercisable as of the date of this Agreement, and
(g) the date on which such Compaq Option expires.

                                     A-35



   5.10 Form S-8.  HP agrees to file a registration statement on Form S-8 for
the shares of HP Common Stock issuable with respect to assumed Compaq Options
to the extent Form S-8 is available as soon as is reasonably practicable after
the Effective Time and shall maintain the effectiveness of such registration
statement thereafter for so long as any of such options or other rights remain
outstanding.

   5.11 Indemnification.

   (a) Indemnity.  From and after the Effective Time, HP will, and will cause
the Surviving Corporation to, fulfill and honor in all respects the obligations
of Compaq pursuant to any indemnification agreements between Compaq and its
directors and officers immediately prior to the Effective Time (the
"Indemnified Parties"), subject to applicable law. The Certificate of
Incorporation and Bylaws of the Surviving Corporation will contain provisions
with respect to exculpation and indemnification that are at least as favorable
to the Indemnified Parties as those contained in the Certificate of
Incorporation and Bylaws of the Company as in effect on the date hereof, which
provisions will not be amended, repealed or otherwise modified for a period of
six years from the Effective Time in any manner that would adversely affect the
rights thereunder of individuals who, immediately prior to the Effective Time,
were directors, officers, employees or agents of Compaq, unless such
modification is required by law.

   (b) Insurance.  For a period of six years after the Effective Time, HP will
cause the Surviving Corporation to use all reasonable efforts to cause to be
maintained in directors' and officers' liability insurance maintained by Compaq
covering those persons who are covered by Compaq's directors' and officers'
liability insurance policy as of the date hereof on terms comparable to those
applicable to the current directors and officers of Compaq for a period of six
(6) years; provided, however, that in no event will the Surviving Corporation
be required to expend in excess of one hundred fifty percent (150%) of the
annual premium currently paid by Compaq for such coverage (and to the extent
annual premium would exceed one hundred fifty percent (150%) of the annual
premium currently paid by Compaq for such coverage, the Surviving Corporation
shall use all reasonable efforts to cause to be maintained the maximum amount
of coverage as is available for such one hundred fifty percent (150%) of such

that (i) there will be at least one Compaq Designated Director on each

which Rule 145 promulgated under the Securities Act applies and may only be
transferred (i) in conformity with Rule 145 or (ii) in accordance with a
written opinion of counsel, reasonably acceptable to HP, in form and substance
that such transfer is exempt from registration under the Securities Act.

   5.15 Treatment as Reorganization.  None of HP, Merger Sub or Compaq shall,
and they shall not permit any of their respective Subsidiaries to, take any

Rights Dividend not later than September 27, 2001. Compaq shall not redeem the
Compaq Rights or amend or modify (including by delay of the "Distribution Date"

unless, and only to the extent that: (i) it is required to do so by order of a
court of competent jurisdiction or (ii) its Board of Directors has concluded in
good faith, after receipt of advice of its outside legal counsel, that, in

(including by delay of the "Distribution Date" thereunder) or terminate the HP
Rights Plan prior to the Effective Time unless, and only to the extent that:
(i) it is required to do so by order of a court of competent jurisdiction or
(ii) its Board of Directors has concluded in good faith, after receipt of
advice of its outside legal counsel, that, in light of a Superior Offer with
respect to it, the failure to effect such amendment,

                                     A-37



modification or termination is reasonably likely to result in a breach of its
Board of Directors' fiduciary obligations to its stockholders under applicable
law.

   5.17 Section 16 Matters.  Prior to the Effective Time, HP and Compaq shall
take all such steps as may be required (to the extent permitted under
applicable law) to cause any dispositions of Compaq Common Stock (including
derivative securities with respect to Compaq Common Stock) or acquisitions of
HP Common Stock (including derivative securities with respect to HP Common
Stock) resulting from the transactions contemplated by Article I of this
Agreement by each individual who is subject to the reporting requirements of
Section 16(a) of the Exchange Act with respect to Compaq to be exempt under
Rule 16b-3 promulgated under the Exchange Act.

   5.18 Merger Sub Compliance.  HP shall cause Merger Sub to comply with all of

transfer, value added, stock transfer or stamp taxes, any transfer, recording,
registration or other fees or any similar taxes which become payable in
connection with the transactions contemplated by this Agreement that are

payment; provided, however, that, as between HP and Compaq, Compaq shall pay on
behalf of those Persons holding Compaq Common Stock immediately prior to the
Effective Time any real estate transfer or similar Taxes payable by such Person
in connection with Merger.

   Authority (i) challenging or seeking to restrain or prohibit the

   effect a Restricted Divestiture.

      (f) Tax Opinions.  HP and Compaq shall each have received written

   Closing Date (it being understood that, for purposes of determining the
   accuracy of such representations and warranties, any update of or
   modification to the HP Disclosure Letter made or purported to have been made
   after the execution of this Agreement shall be disregarded). Compaq shall
   have received a certificate with respect to the foregoing signed on behalf

   representations and warranties, any update of or modification to the Compaq
   Disclosure Letter made or purported to have been made after the

                                     A-39

   6.2(b) would not be satisfied as of the time of such breach or as of the
   time such representation or warranty shall have become untrue, provided that
   if such inaccuracy in HP's representations and warranties or breach by HP is
   curable by HP prior to the End Date through the exercise of reasonable
   efforts, then Compaq may not terminate this Agreement under this Section
   7.1(h) prior to sixty (60) days following the receipt of written notice from
   Compaq to HP of such breach, provided that HP continues to exercise all
   reasonable efforts to cure such breach through such sixty (60) day period
   (it being understood that Compaq may not terminate this Agreement pursuant
   to this paragraph (h) if it shall have materially breached this Agreement or

      (iii) Interest and Costs; Other Remedies.  Each of HP and Compaq
   acknowledges that the agreements contained in this Section 7.3(b) are an
   integral part of the transactions contemplated by this Agreement, and that,
   without these agreements, the other party hereto would not enter into this
   Agreement; accordingly, if HP or Compaq, as the case may be, fails to pay in
   a timely manner the amounts due pursuant to this Section 7.3(b), and, in

   recapitalization, liquidation, dissolution or similar transaction involving
   the party pursuant to which the stockholders of the party immediately

the parties hereto, by action taken or authorized by their respective Boards of
Directors, at any time before or after approval of the matters presented in

disclosure made in Compaq Disclosure Letter with regard to a representation of
Compaq, or in the HP Disclosure Letter with regard to a representation of HP or

such party to which such exception or disclosure is clearly relevant.

   (b) For purposes of this Agreement, the term "Knowledge" means, with respect
to a party hereto, with respect to any matter in question, that any of the

   (c) For purposes of this Agreement, the term "Material Adverse Effect," when
used in connection with an entity, means any change, event, violation,
inaccuracy, circumstance or effect (any such item, an "Effect"), individually
or when taken together with all other Effects that have occurred prior to the
date of determination of the occurrence of the Material Adverse Effect, that is
or is reasonably likely to (i) be materially adverse to the business, assets
(including intangible assets), capitalization, financial condition or results
of operations of such entity taken as a whole with its Subsidiaries (or, if
such entity is Compaq, Compaq taken as a whole with its Subsidiaries or HP
taken as a whole with its Subsidiaries) or (ii) materially impede the authority
of such entity, or, in any case, HP, to consummate the transactions
contemplated by this Agreement in accordance with the terms hereof and
applicable Legal Requirements; provided, however, that, for purposes of clause
(i) above, in no event shall any of the following, alone or in combination, be
deemed to constitute, nor shall any of the following be taken into account in
determining whether there has been or will be, a Material Adverse Effect on any
entity: (A) any Effect resulting from compliance with the terms and conditions
of this Agreement, (B) any Effect resulting from the announcement or pendency
of the Merger (provided that the exception in this clause (B) shall not apply
to the use of the term "Material Adverse Effect" in Sections 6.2(a) and 6.3(a)
with respect to the representations and warranties contained in Section 2.3,
Section 2.7(b), Section 2.14, Section 3.3 and Section 3.13), (C) any change in
such entity's stock price or trading volume, in and of itself, (D) any failure
by such entity to meet published revenue or earnings projections, in and of
itself, (E) any Effect that results from changes affecting any of the
industries in which such entity operates generally or the United States economy
generally (which changes in each case do not disproportionately affect such
entity in any material respect), (F) any Effect that results from changes
affecting general worldwide economic or capital market conditions (which
changes in each case do not disproportionately affect such entity in any
material respect), or (G) stockholder class action litigation arising from
allegations of a breach of fiduciary duty relating to this Agreement.

   (d) For purposes of this Agreement, the term "Person" shall mean any
individual, corporation (including any non-profit corporation), general
partnership, limited partnership, limited liability partnership, joint venture,

                                     A-45



estate, trust, company (including any limited liability company or joint stock
company), firm or other enterprise, association, organization, entity or
Governmental Entity.

   8.4 Counterparts.  This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each
of the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

   8.5 Entire Agreement; Third-Party Beneficiaries.  This Agreement and the
documents and instruments and other agreements among the parties hereto as
contemplated by or referred to herein, including the Compaq Disclosure Letter
and the HP Disclosure Letter (i) constitute the entire agreement among the
parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof, it being understood that the
Confidentiality Agreement shall continue in full force and effect until the
Closing and shall survive any termination of this Agreement and (ii) are not
intended to confer upon any other Person any rights or remedies hereunder,
except as specifically provided, following the Effective Time, in Section 5.11.
Without limiting the foregoing, it is expressly understood and agreed that the
provisions of Sections 5.9(d), 5.9(e), 5.12(b) and 5.12(c) are statements of
intent and no Continuing Employee or other Person (including any party hereto)
shall have any rights or remedies, including rights of enforcement, with
respect thereto and no Continuing Employee or other Person is or is intended to
be a third-party beneficiary thereof.

   8.6 Severability.  In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other Persons or circumstances will be interpreted so as
reasonably to effect the intent of the parties hereto. The parties further
agree to replace such void or unenforceable provision of this Agreement with a
valid and enforceable provision that will achieve, to the greatest extent
possible, the economic, business and other purposes of such void or
unenforceable provision.

   8.7 Other Remedies; Specific Performance.

   (a) Other Remedies.  Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity
upon such party, and the exercise by a party of any one remedy will not
preclude the exercise of any other remedy. The parties hereto agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached.

   (b) Specific Performance.  It is accordingly agreed that the parties shall
be entitled to seek an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions hereof in any
court of the United States or any state having jurisdiction, this being in
addition to any other remedy to which they are entitled at law or in equity.

   8.8 Governing Law.  This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of law thereof.

   8.9 Rules of Construction.  The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule
of construction providing that ambiguities in an agreement or other document
will be construed against the party drafting such agreement or document.

                                     A-46



   8.10 Assignment.  No party may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written approval
of the other parties. Any purported assignment in violation of this Section
8.10 shall be void. Subject to the preceding sentence, this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns.

   8.11 Waiver of Jury Trial.  EACH OF HP, MERGER SUB AND COMPAQ HEREBY
IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE ACTIONS OF HP, MERGER SUB OR COMPAQ IN THE
NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.

Ladies and Gentlemen:

You have requested our opinion as to the fairness from a financial point of
view to Hewlett-Packard Company ("Hewlett-Packard") of the exchange ratio (the
"Exchange Ratio") of 0.6325 shares of Common Stock, par value $0.01 per share
(the "Hewlett-Packard Shares"), of Hewlett-Packard to be exchanged by
Hewlett-Packard for each share of Common Stock, par value $0.01 per share (the
"Compaq Shares"), of Compaq Computer Corporation ("Compaq") pursuant to the
Agreement and Plan of Reorganization; dated as of September 3, 2001 (the
"Agreement"), by and among Hewlett-Packard, Heloise Merger Corporation, a
wholly owned subsidiary of Hewlett-Packard, and Compaq.

Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. We are
familiar with Hewlett-Packard having provided investment banking services to
Hewlett-Packard from time to time, including having acted as co-manager on the
initial public offering of shares of Common Stock, par value $0.01 per share
(the "Agilent Shares"), of Agilent Technologies Inc. ("Agilent"), an affiliate
of Hewlett-Packard, in November 1999; having acted as manager of public
offerings of debt securities of Hewlett-Packard in June 2000 (aggregate
principal amount $1.5 billion), in July 2001 (aggregate principal amount $750
million) and in August 2001 (aggregate principal amount $50 million); and
having acted as its financial advisor in connection with, and having
participated in certain of the negotiations leading to, the Agreement. We also
have provided certain investment banking services to Compaq from time to time.
Goldman Sachs provides a full range of financial advisory and securities
services and, in the course of its normal trading activities, may from time to
time effect transactions and hold securities, including derivative securities,
of Hewlett-Packard or Compaq for its own account and for the accounts of
customers. As of August 31, 2001, Goldman Sachs accumulated a net long position
of 451,315 Hewlett-Packard Shares, a net long position of 160,896 Compaq Shares
and a net long position of convertible bonds of Compaq with an aggregate
principal amount of $42,400,000.

In connection with this opinion, we have reviewed, among other things, the
Agreement; Annual Reports to Stockholders and Annual Reports on Form 10-K of
Hewlett-Packard for the five fiscal years ended October 31, 2000 and Annual
Reports to Stockholders on Form 10-K of Compaq for the five years ended
December 31, 2000; certain interim reports to stockholders and Quarterly
Reports on Form 10-Q of Hewlett-Packard and Compaq; certain other
communications from Hewlett-Packard and Compaq to their respective
stockholders; and certain internal financial analyses and forecasts for
Hewlett-Packard and Compaq prepared by

                                      B-1

their respective managements, including certain cost savings and operating
synergies projected by the management of Hewlett-Packard to result from the
transaction contemplated by the Agreement (the "Synergies"). We also have held
discussions with members of the senior management of Hewlett-Packard and Compaq
regarding their assessment of the strategic rationale for, and the potential
benefits of, the transaction contemplated by the Agreement and the past and
current business operations, financial condition and future prospects of their
respective companies. In addition, we have reviewed the reported price and
trading activity for the Hewlett-Packard Shares and the Compaq Shares, compared
certain financial and stock market information for Hewlett-Packard and for
Compaq with similar information for certain other companies the securities of
which are publicly traded, reviewed the financial terms of certain recent
business combinations in the computer hardware industry specifically and in
other industries generally and performed such other studies and analyses as we
considered appropriate.

We have relied upon the accuracy and completeness of all of the financial,
accounting and other information discussed with or reviewed by us and have
assumed such accuracy and completeness for purposes of rendering this opinion.
In that regard, we have assumed with your consent that the internal financial
forecasts prepared by the managements of Hewlett-Packard and Compaq, including
the Synergies, have been reasonably prepared on a basis reflecting the best
currently available estimates and judgments of Hewlett-Packard and Compaq, and
that such Synergies will be realized in the amounts and time periods
contemplated thereby. In addition, we have not made an independent evaluation
or appraisal of the assets and liabilities of Hewlett-Packard or Compaq or any
of their subsidiaries and we have not been furnished with any such evaluation
or appraisal. We also have assumed that all material governmental, regulatory
or other consents and approvals necessary for the consummation of the
transaction contemplated by the Agreement will be obtained without any
meaningful adverse effect on Hewlett-Packard or Compaq or on the contemplated
benefits of the transaction contemplated by the Agreement. Our advisory
services and the opinion expressed herein are provided for the information and
assistance of the Board of Directors of Hewlett-Packard in connection with its
consideration of the transaction contemplated by the Agreement and such opinion
does not constitute a recommendation as to how any holder of Hewlett-Packard
Shares should vote with respect to such transaction.

Based upon and subject to the foregoing and based upon such other matters as we
consider relevant, it is our opinion that as of the date hereof the Exchange
Ratio is fair from a financial point of view to Hewlett-Packard.

Very truly yours,

/s/ Goldman, Sachs & Co.

September 3, 2001

The Board of Directors
Compaq Computer Corporation
20555 State Highway 249
Houston, TX 77070

Ladies and Gentlemen:

   You have requested our opinion as investment bankers as to the fairness,
from a financial point of view, to the holders of the common stock of Compaq
Computer Corporation (the "Company"), par value $0.01 per share ("Company
Common Stock"), of the Exchange Ratio (as defined below) in connection with the
Merger (as defined below) contemplated by the Agreement and Plan of Merger (the
"Agreement") to be entered into by and among the Company, Hewlett Packard
Corporation ("Parent") and Heloise Merger Corporation, a wholly-owned
subsidiary of Parent ("Merger Sub").

   As more fully described in the Agreement, Merger Sub will merge with and
into the Company (the "Merger") and each outstanding share of Company Common
Stock (other than certain shares specified in the Agreement) will be converted
into the right to receive 0.6325 (the "Exchange Ratio") of a share of the
common stock of Parent, par value $0.01 per share ("Parent Common Stock").

   In connection with rendering our opinion, we have, among other things,
reviewed a September 3, 2001 draft of the Agreement in the form provided to us
and held discussions with certain senior officers and other representatives and
advisors of the Company and Parent concerning the businesses, operations and
prospects of the Company and Parent. We examined certain publicly available
business and financial information relating to the Company and Parent and the
industries in which they operate, as well as certain financial forecasts and
information relating to certain strategic implications and operational benefits
anticipated to result from the Merger, and other information and data regarding
the Company and Parent which were provided to or otherwise discussed with us by
the management of the Company and Parent. We reviewed the financial terms of
the Merger, as set forth in the draft of the Agreement provided to us, in
relation to, among other things, current and historical market prices and
trading volumes of Company Common Stock and Parent Common Stock; the historical
and projected earnings and other operating data of the Company and Parent; and
the historical and projected capitalization and financial condition of the
Company and Parent. We considered, to the extent publicly available, the
financial terms of certain similar transactions recently effected or proposed
which we considered relevant in evaluating the Merger and analyzed certain
financial, stock market, economic and other publicly available information
relating to the businesses of other companies whose operations we considered
relevant in evaluating those of the Company and Parent. In addition to the
foregoing, we conducted such other analyses and examinations and considered
such other information and financial, economic and market criteria as we deemed
appropriate in arriving at our opinion.

   In our review and analysis and in arriving at our opinion, we have assumed
and relied upon, without assuming any responsibility for independent
verification, the accuracy and completeness of all of the financial and other
information and data publicly available or furnished to, discussed with or
otherwise reviewed by or for us. With respect to financial forecasts and
information relating to certain strategic implications and operational benefits
anticipated to result from the Merger provided to us or otherwise reviewed by
or discussed with us regarding the Company and Parent, we have been advised by
the management of the Company and Parent that such forecasts and other
information were reasonably prepared on bases reflecting the best currently
available estimates and judgments of the management of the Company and Parent,
as the case may be. We express no view with respect to such forecasts and other
information or the assumptions on which they are based. We have

                                      C-1



Board of Directors
Compaq Computer Corporation

assumed that the Merger will be treated as a tax-free reorganization for United
States federal income tax purposes. We have not made or been provided with an
independent evaluation or appraisal of the assets or liabilities (contingent or
otherwise) of the Company or Parent, nor have we made any physical inspection
of the properties or assets of the Company or Parent.

   For purposes of rendering our opinion, we have assumed that the
representations and warranties of each party contained in the Agreement are
true and correct in all material respects and that each party will perform all
of the covenants and agreements required to be performed by it under the
Agreement. You have advised us, and we have assumed, that the final terms of
the Agreement will not vary materially from those set forth in the draft
provided to us. We have further assumed that the Merger will be consummated in
accordance with the terms of the Agreement without waiver of any of the
conditions precedent to the Merger contained in the Agreement. We have also
assumed that all material governmental, regulatory or other consents and
approvals will be obtained and that in the course of obtaining any necessary
governmental, regulatory or other consents and approvals, or any amendments,
modifications or waivers to any documents to which either the Company or Parent
is a party, as contemplated by the Agreement, no restrictions will be imposed
or amendments, modifications or waivers made that would have any material
adverse effect on our analysis.

   Our opinion, as set forth herein, relates to the relative values of the
Parent and the Company and does not imply any conclusion as to the likely
trading range for Company Common Stock or Parent Common Stock following the
announcement or consummation of the Merger, which range may vary depending
upon, among other factors, changes in interest rates, dividend rates, market
conditions, general economic conditions and other factors that generally
influence the price of securities. We were not requested to consider, and our
opinion does not address, the relative merits of the Merger as compared to any

Item 20.  Indemnification of Officers and Directors

   Section 145 of the General Corporation Law of the State of Delaware
authorizes a court to award or a corporation's board of directors to grant
indemnification to directors and officers in terms that are sufficiently broad
to permit indemnification under certain circumstances for liabilities
(including reimbursement for expenses incurred) arising under the Securities
Act of 1933. HP's certificate of incorporation contains a provision eliminating
the personal liability of its directors to the company or its shareowners for
breach of fiduciary duty as a director to the fullest extent permitted by
applicable law. HP's bylaws provide for the mandatory indemnification of our
directors and officers to the maximum extent permitted by Delaware law. HP's
bylaws also provide (i) that we may expand the scope of the indemnification by
individual contracts with our directors and officers, and (ii) that we shall
not be required to indemnify any director or officer unless the indemnification
is required by law, if the proceeding in which indemnification is sought was
brought by a director or officer, it was authorized in advance by our board of
directors, the indemnification is provided by us, in our sole discretion
pursuant to powers vested in us under the Delaware law, or the indemnification
is required by individual contract. In addition, our bylaws give us the power
to indemnify our employees and agents to the maximum extent permitted by
Delaware law.

Item 22.  Undertakings

   The undersigned registrant hereby undertakes:

      (1) that, for purposes of determining any liability under the Securities
   Act of 1933, each filing of the registrant's annual report pursuant to
   Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and,
   where applicable, each filing of an employee benefit plan's annual report
   pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
   incorporated by reference into this registration statement shall be deemed
   to be a new registration statement relating to the securities offered
   therein, and the offering of such securities at that time shall be deemed to
   be the initial bona fide offering thereof;

      (2) insofar as indemnification for liabilities under the Securities Act
   of 1933 may be permitted to directors, officers and controlling persons of
   the registrant pursuant to the provisions described in Item 20 above, or
   otherwise, the registrant has been advised that, in the opinion of the
   Securities and Exchange Commission, such indemnification is against public
   policy as expressed in the Securities Act and is therefore unenforceable. If
   a claim of indemnification against such liabilities (other than the payment
   by the registrant of expenses incurred or paid by a director, officer or
   controlling person of the registrant in a successful defense of any action,
   suit or proceeding) is asserted by such director, officer, or controlling
   person in connection with the securities being registered, the registrant
   will, unless in the opinion of its counsel the matter has been settled by
   controlling precedent, submit to a court of appropriate jurisdiction the
   question whether such indemnification by it is against public policy as
   expressed in the Securities Act and will be governed by the final
   adjudication of such issue;

      (3) to respond to requests for information that is incorporated by
   reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this
   Form S-4, within one business day of receipt of any such request, and to
   send the incorporated documents by first class mail or other equally prompt
   means. This includes information contained in documents filed after the
   effective date of the registration statement through the date of responding
   to such request; and

      (4) to supply by means of a post-effective amendment all information
   concerning a transaction, and the company being acquired involved therein,
   that was not the subject of and included in the registration statement when
   it became effective.
