OFFER TO EXCHANGE

$800,000,000 principal amount of our

5.75% Senior Notes due 2016,

which have been registered under the Securities Act,

for any and all of our outstanding unregistered 5.75% Senior Notes due 2016

     We are offering to exchange up to $800,000,000 of our 5.75% Senior Notes due 2016, or the “exchange notes,” for our currently outstanding 5.75% Senior Notes due 2016, or the “private notes.” We refer to the private notes and the exchange notes collectively as the “notes.” The exchange notes are substantially identical to the private notes, except that the exchange notes have been registered under the federal securities laws and will not bear any legend restricting their transfer. The exchange notes will represent the same debt as the private notes, and we will issue the exchange notes under the same indenture. The notes will mature on April 1, 2016. Interest on the notes is payable on April 1 and October 1 of each year, commencing on October 1, 2006.

     We may redeem some or all of the notes at any time and from time to time at the redemption prices described under “Description of Exchange Notes—Redemption at the Option of Allergan.” The notes will be Allergan’s unsecured senior obligations and not the obligations of its subsidiaries. The notes rank junior in right of payment to the rights of our secured creditors to the extent of their security in our assets; equal in right of payment to the rights of creditors under our other existing and future unsecured unsubordinated obligations, including our revolving credit facilities, our medium term notes and the other debt we incurred concurrently with the settlement of the notes, as described in this prospectus; senior in right of payment to the rights of creditors under obligations expressly subordinated to the notes; and effectively subordinated to secured and unsecured creditors of our subsidiaries.

Material Terms of the Exchange Offer

     Each broker-dealer that receives exchange notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such exchange notes. By so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of exchange notes received in exchange for private notes where the exchange notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed that, starting on the expiration of the exchange offer and ending on the close of business one year after the expiration of the exchange offer, we will make this prospectus available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

     Our common stock is quoted on the New York Stock Exchange under the symbol “AGN.” The closing price of our common stock on the New York Stock Exchange on October 5, 2006, was $114.61 per share.

      Please refer to “Risk Factors” beginning on page 7 of this prospectus for a description of the risks you should consider before participating in the exchange offer.

Risk Factors		See “Risk Factors” and other information in this prospectus for a discussion of factors you should carefully consider prior to participating in the exchange offer.

RISK FACTORS

      Investing in the notes involves a high degree of risk. You should carefully consider the following risk factors and the risk factors identified in our most recent annual report on Form 10-K and any subsequent Quarterly Report on Form 10-Q incorporated herein by reference, as well as all other information contained or incorporated by reference in this prospectus before making a decision to invest in the exchange notes. The occurrence of any one or more of the following could materially adversely affect your investment in the notes or our business and operating results.

      The notes are exclusively the obligations of Allergan and not its subsidiaries. We currently conduct almost all of our operations through our subsidiaries and our subsidiaries have significant liabilities. In addition, we may, and in some cases we have plans to, conduct additional operations through our subsidiaries in the future and, accordingly, our subsidiaries’ liabilities will increase. Our cash flow and our ability to service our debt, including the notes, therefore depends significantly upon the earnings of our subsidiaries, and we depend on the distribution of earnings, loans or other payments by those subsidiaries to us. As of June 30, 2006, our subsidiaries had total liabilities of $325.7 million.

      Our subsidiaries are separate and distinct legal entities. Our subsidiaries have no obligation to pay any amounts due on the notes or, subject to existing or future contractual obligations between us and our subsidiaries, to provide us with funds for our payment obligations, whether by dividends, distributions, loans or other payments. In addition, any payment of dividends, distributions, loans or advances by our subsidiaries to us could be subject to statutory or contractual restrictions and taxes on distributions. Payments to us by our subsidiaries will also be contingent upon our subsidiaries’ earnings and business considerations.

      Our right to receive any assets of any of our subsidiaries upon liquidation or reorganization, and, as a result, the right of the holders of the notes to participate in those assets, will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors and preferred stockholders, if any. The notes do not restrict the ability of our subsidiaries to incur additional liabilities. In addition, even if we were a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of our subsidiaries and any indebtedness of our subsidiaries senior to indebtedness held by us.

      We have a significant amount of debt and substantial debt service requirements. As of June 30, 2006, we had approximately $1.7 billion of outstanding debt, giving pro forma effect to the Financing Transactions and the application of the proceeds, including the issuance of the private notes, the issuance of the Convertible Notes, the redemption of our 2022 Notes and the repayment of the Bridge Facility. Giving effect to the Financing Transactions, the redemption of our 2022 Notes and the issuance of the Convertible Notes, as of June 30, 2006, we have the ability to borrow an additional approximately $741.0 million under our long-term credit facility.

      This level of debt could have significant consequences on our future operations, including:

      If we are unable to generate sufficient cash flow or otherwise obtain funds necessary to make required payments, or if we fail to comply with the various requirements of the notes, our existing indebtedness, debt we incur in connection with the Financing Transactions or any indebtedness that we may incur in the future, we would be in default, which could permit the holders of the notes and the holders of such other indebtedness to accelerate the maturity of the notes or such other indebtedness, as the case may be, and could cause defaults under the notes and such other indebtedness. Any default under the notes or any indebtedness that we may incur in the future, as well as any of the above-listed factors, could have a material adverse effect on our business, operating results, liquidity and financial condition and our ability to meet our payment obligations under the notes and our other debt.

      We and our subsidiaries may incur substantial additional debt in the future. Although certain of our debt agreements contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and the indebtedness incurred in compliance with these restrictions could be substantial. Also, these restrictions do not prevent us from incurring obligations that do not constitute “indebtedness” as defined in the relevant agreement. If new debt is added to our current debt levels, the related risks that we now face could intensify.

      The notes will not be secured by any of our assets. Future indebtedness that we incur may be secured by our assets. If we become insolvent or are liquidated, or if payment of any secured indebtedness is accelerated, the holders of the secured indebtedness will be entitled to exercise the remedies available to secured lenders under applicable law, including the ability to foreclose on and sell the assets securing such indebtedness in order to satisfy such indebtedness. In any such case, any remaining assets may be insufficient to repay the notes.

      The agreements governing our existing debt contain covenant restrictions that limit our ability to operate our business, including covenant restrictions that may prevent us from:

      Some of our existing debt agreements require us to maintain specific leverage and interest coverage ratios. Our ability to comply with these covenants is dependent on our future performance, which will be subject to many factors, some of which are beyond our control, including prevailing economic conditions. Our failure to comply with these obligations would prevent us from borrowing additional money and could result in our default. If a default occurs under any of our senior indebtedness, the relevant lenders could elect to declare such indebtedness, together with accrued interest and other fees, to be immediately due and payable

and proceed against substantially all of our assets. Moreover, if the lenders under a facility or other agreement in default were to accelerate the indebtedness outstanding under that facility, it could result in a default under other indebtedness. If all or any part of our indebtedness were to be accelerated, we may not have or be able to obtain sufficient funds to repay it. In addition, we may incur other indebtedness in the future that may contain financial or other covenants that are more restrictive than those contained in the indenture governing the notes.

      As a result of these covenants, our ability to respond to changes in business and economic conditions and to obtain additional financing, if needed, may be significantly restricted, and we may be prevented from engaging in transactions that might otherwise be beneficial to us. In addition, our failure to comply with these covenants could result in a default under the notes and our other debt, which could permit the holders to accelerate such debt. If any of our debt is accelerated, we may not have sufficient funds available to repay such debt.

      Our ability to meet our payment and other obligations under our debt depends on our ability to generate significant cash flow in the future. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors, as well as other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations, or that future borrowings will be available to us under our senior credit facility or otherwise, in an amount sufficient to enable us to meet our payment obligations under the notes and our other debt and to fund other liquidity needs.

      There is currently no public market for the notes, and an active trading market may never develop. If the notes are traded, they may trade at a discount from their offering price, depending on prevailing interest rates, the market for similar securities, our ability to affect the exchange offer, our performance and other factors. To the extent that an active trading market does not develop, the liquidity and trading prices for the exchange notes may be harmed.

      We have no plans to list the exchange notes on a securities exchange.

      Any market-making activity, if initiated, may be discontinued at any time, for any reason or for no reason, without notice.

      The liquidity of any market for the exchange notes will depend upon the number of holders of the exchange notes, our results of operations and financial condition, the market for similar securities, the interest of securities dealers in making a market in the exchange notes and other factors. An active or liquid trading market for the exchange notes may not develop.

      One or more rating agencies may lower the ratings on the notes. If the rating agencies reduce their ratings on the notes in the future or indicate that they have their ratings on the notes under surveillance or review with possible negative implications, the value of the notes could decline. In addition, a ratings downgrade could adversely affect our ability to access capital.

      We will only issue exchange notes in exchange for private notes that are timely received by the exchange agent. Therefore, you should allow sufficient time to ensure timely delivery of the private notes and you should carefully follow the instructions on how to tender your private notes. Neither we nor the exchange agent is required to tell you of any defects or irregularities with respect to your tender of the private notes. If you do not tender your private notes or if we do not accept your private notes because you did not tender your private notes properly, then, after we consummate the exchange offer, you may continue to hold private notes that are subject to the existing transfer restrictions. In addition, if you tender your private notes for the

purpose of participating in a distribution of the exchange notes, you will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale of the exchange notes. If you are a broker-dealer that receives exchange notes for your own account in exchange for private notes that you acquired as a result of market-making activities or any other trading activities, you will be required to acknowledge that you will deliver a prospectus in connection with any resale of such exchange notes.

      After the exchange offer is consummated, if you continue to hold any private notes, you may have difficulty selling them because there will be less private notes outstanding. In addition, if a large amount of private notes are not tendered or are tendered improperly, the limited amount of exchange notes that would be issued and outstanding after we consummate the exchange offer could lower the market price of such exchange notes.

RATIO OF EARNINGS TO FIXED CHARGES

      The following table sets forth our historical ratio of earnings to fixed charges for the last five years and the six month period ended June 30, 2006, and the pro forma Allergan-Inamed combined ratio of earnings to fixed charges for the year ended December 31, 2005 and the six month period ended June 30, 2006, giving effect to our acquisition of Inamed, the completion of the Financing Transactions, the redemption of our 2022 Notes and the repayment of the Bridge Facility, as if each of those transactions had been consummated on January 1, 2005. For the purpose of these ratios, “earnings” represents earnings before provision for income taxes and minority interest and fixed charges, and “fixed charges” consist of interest expense and a share of rent expense which is deemed to be representative of an interest factor.

USE OF PROCEEDS

      The exchange offer satisfies an obligation under the registration rights agreement. We will not receive any cash proceeds from the exchange offer.

SELECTED FINANCIAL DATA

      The selected consolidated financial data below for the five years ended December 31, 2005 should be read in conjunction with the consolidated financial statements and accompanying notes thereto filed in our Annual Report on Form 10-K filed with the SEC on March 6, 2006. The financial data for the six months ended June 24, 2005 and June 30, 2006 is derived from our unaudited consolidated condensed financial statements. The unaudited results reflect all adjustments (consisting only of normal recurring adjustments) that our management considers necessary for a fair presentation of operating results. The operating results for the six months ended June 30, 2006 are not necessarily indicative of the results that will be achieved for a full year. The information is only a summary and should be read in connection with the consolidated financial statements, accompanying notes and management’s discussion and analysis of results of operations and financial condition of Allergan, Inc., all of which can be found in publicly available documents, including those incorporated by reference. See “Where You Can Find More Information.”

      The financial data above has been recast to reflect the results of operations and financial positions of our ophthalmic surgical and contact lens care businesses as a discontinued operation. The results of operations for our discontinued operations include allocations of certain Allergan expenses to those operations. These amounts have been allocated on the basis that is considered by management to reflect most fairly or reasonably the utilization of the services provided to, or the benefit obtained by, those operations.

THE EXCHANGE OFFER

Purpose of the Exchange Offer

      We sold the private notes on April 12, 2006 to the initial purchasers pursuant to a purchase agreement. The initial purchasers subsequently sold the private notes to “qualified institutional buyers,” as defined in Rule 144A under the Securities Act, in reliance on Rule 144A and to certain persons outside the United States in reliance on Regulation S of the Securities Act. As a condition to the sale of the private notes, we entered into a registration rights agreement with the initial purchasers on April 12, 2006. Pursuant to the registration rights agreement, we agreed that, unless the exchange offer is not permitted by applicable law or Securities and Exchange Commission policy, we would:

      Upon the effectiveness of this registration statement, we will offer the exchange notes in exchange for the private notes. We filed a copy of the registration rights agreement as an exhibit to our current report on Form 8-K filed with the Securities and Exchange Commission on April 12, 2006, announcing the closing of the sale of the private notes.

Resale of the Exchange Notes

      We are making the exchange offer in reliance on the position of the staff of the Securities and Exchange Commission as set forth in interpretive letters addressed to third parties in other transactions. For further information on the Securities and Exchange Commission’s position, see Exxon Capital Holdings Corporation, available May 13, 1988, Morgan Stanley & Co. Incorporated, available June 5, 1991 and Shearman & Sterling, available July 2, 1993, and other interpretive letters to similar effect. We have not sought our own interpretive letter, however, and we cannot assure you that the staff would make a similar determination with respect to the exchange offer as it has in interpretive letters to third parties. Based on these interpretations by the staff, we believe that the exchange notes issued under the exchange offer may be offered for resale, resold or otherwise transferred by you, without further compliance with the registration and prospectus delivery provisions of the Securities Act, so long as:

      By tendering the private notes in exchange for exchange notes, you will be required to represent to us that each of the above statements applies to you. If you are participating in, or intend to participate in, a distribution of the exchange notes, or have any arrangement or understanding with any person to participate in a distribution of the exchange notes to be acquired in this exchange offer, you may be deemed to have received restricted securities and may not rely on the applicable interpretations of the staff of the Securities and Exchange Commission. If you are so deemed, you will have to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any secondary resale transaction.

      Each broker-dealer that receives exchange notes for its own account in exchange for private notes, which the broker-dealer acquired as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of the exchange notes. By so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. A broker-dealer may use this prospectus, as it may be amended or supplemented from time to time, in connection with resales of exchange notes received in exchange for private notes which the broker-dealer acquired as a result of market-making or other trading activities.

Terms of the Exchange Offer

      Upon the terms and subject to the conditions described in this prospectus, we will accept any and all private notes validly tendered and not withdrawn before the expiration date. You may tender outstanding private notes only in denominations of $2,000 and integral multiples of $1,000.

      The form and terms of the exchange notes are the same as the form and terms of the private notes except that:

      The exchange notes will evidence the same debt as the private notes and will be issued under the same indenture, so the exchange notes and the private notes will be treated as a single class of debt securities under the indenture.

      As of the date of this prospectus, $800,000,000 in aggregate principal amount of the private notes are outstanding and registered in the name of Cede & Co., as nominee for The Depository Trust Company, or DTC. Only a registered holder of the private notes, or such holder’s legal representative or attorney-in-fact, as reflected on the records of the trustee under the indenture, may participate in the exchange offer. We will not set a fixed record date for determining registered holders of the private notes entitled to participate in the exchange offer.

      You do not have any appraisal or dissenters’ rights under the indenture in connection with the exchange offer. We intend to conduct the exchange offer in accordance with the provisions of the registration rights agreement and the applicable requirements of the Securities Act, the Exchange Act and the rules and regulations of the Securities and Exchange Commission.

      We will be deemed to have accepted validly tendered private notes when, as and if we had given oral or written notice of acceptance to the exchange agent. The exchange agent will act as your agent for the purposes of receiving the exchange notes from us.

Expiration Date; Extensions; Amendments

      The term “expiration date” will mean 5:00 p.m., New York City time on November 7, 2006, unless we, in our sole discretion, extend the exchange offer, in which case the term “expiration date” will mean the latest date and time to which we extend the exchange offer.

      To extend the exchange offer, we will:

each before 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date.

      We reserve the right, in our reasonable discretion:

      We will follow any delay in acceptance, extension or termination as promptly as practicable by oral or written notice to the exchange agent and a press release or oral or written notice to the holders of the private notes. If we amend the exchange offer in a manner we determine constitutes a material change, we will promptly disclose the amendment in a prospectus supplement that we will distribute to the registered holders. We will also extend the exchange offer for a period of five to ten business days, depending upon the significance of the amendment and the manner of disclosure, if the exchange offer would otherwise expire during the five to ten business day period.

Interest on the Exchange Notes

      The exchange notes will bear interest at the same rate and on the same terms as the private notes. Consequently, the exchange notes will bear interest at a rate equal to 5.75% per annum. Interest will be payable semi-annually in arrears on April 1 and October 1, commencing October 1, 2006.

      Interest on the exchange notes will accrue from the last interest payment date on which interest was paid on the private notes or, if no interest was paid on the private notes, from the date of issuance of the private notes, which was April 12, 2006. We will deem the right to receive any interest accrued on the private notes waived by you if we accept your private notes for exchange.

Procedures for Tendering

      If you are a DTC participant that has private notes which are credited to your DTC account also by book-entry and which are held of record by DTC’s nominee, you may tender your private notes by book-entry transfer as if you were the record holder. Because of this, references in this prospectus to registered or record holders include DTC participants with private notes credited to their accounts. If you are not a DTC participant, you may tender your private notes by book-entry transfer by contacting your broker or opening an account with a DTC participant.

      If you wish to tender private notes in the exchange offer, you must cause to be transmitted to the exchange agent an agent’s message, which agent’s message must be received by the exchange agent prior to 5:00 p.m., New York City time, on the expiration date. In addition, the exchange agent must receive a timely confirmation of book-entry transfer of the private notes into the exchange agent’s account at DTC through ATOP under the procedure for book-entry transfers described in this prospectus along with a properly transmitted agent’s message, on or before the expiration date.

      The term “agent’s message” means a message, transmitted by DTC to, and received by, the exchange agent and forming a part of a book-entry confirmation, which states that DTC has received an express acknowledgment from its participant tendering private notes which are the subject of this book-entry

confirmation that this participant has received and agrees to be bound by the terms and subject to the conditions set forth in this prospectus and that we may enforce the agreement against the participant. To receive confirmation of a valid tender of private notes, you should contact the exchange agent at the telephone number listed under “—Exchange Agent.”

      Your tender, if not withdrawn before the expiration date, will constitute a binding agreement between you and us in accordance with the terms and subject to the conditions described in this prospectus. Only a registered holder of private notes may tender the private notes in the exchange offer. If you wish to tender private notes that are registered in the name of a broker, dealer, commercial bank, trust company or other nominee, you should promptly instruct the registered holder to tender on your behalf.

      We will determine in our sole discretion all questions as to the validity, form, eligibility, time of receipt, acceptance and withdrawal of tendered private notes, which determination will be final and binding. We reserve the absolute right to reject any and all private notes not properly tendered or any private notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defects, irregularities or conditions of tender as to particular private notes. Our interpretation of the terms and conditions of the exchange offer will be final and binding on all parties. Unless waived, you must cure any defects or irregularities in connection with tenders of private notes within the time we determine. Although we intend to notify you of defects or irregularities with respect to tenders of private notes, neither we, the exchange agent nor any other person will incur any liability for failure to give you that notification. We will not deem tenders of private notes to have been made until you cure, or we waive, any defects or irregularities.

      While we have no present plan to acquire any private notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any private notes that are not tendered in the exchange offer, we reserve the right in our sole discretion to purchase or make offers for any private notes that remain outstanding after the expiration date. We also reserve the right to terminate the exchange offer, as described under “—Conditions,” and, to the extent permitted by applicable law, purchase private notes in the open market, in privately negotiated transactions or otherwise. The terms of any of those purchases or offers could differ from the terms of the exchange offer.

      By tendering, you will be making several representations to us including that:

      If you are a broker-dealer that will receive exchange notes for your own account in exchange for private notes that were acquired as a result of market-making activities or other trading activities, you will also be required to acknowledge that you will deliver a prospectus in connection with any resale of those exchange notes; however, by so acknowledging and by delivering a prospectus, you will not be deemed to admit that you are an underwriter within the meaning of the Securities Act.

Return of Private Notes

      If we do not accept any tendered private notes for any reason described in the terms and conditions of the exchange offer or if you withdraw or submit private notes for a greater principal amount than you desire to exchange, we will return the unaccepted, withdrawn or non-exchanged notes without expense to you as promptly as practicable. We will credit such private notes to an account maintained at DTC designated by such DTC participant after the expiration date of the exchange offer or the withdrawal or termination of the exchange offer.

Book-Entry Transfer

      The exchange agent will make a request to establish an account with respect to the private notes at DTC for purposes of the exchange offer within two business days after the date of this prospectus. Any financial institution that is a participant in DTC’s systems may make book-entry delivery of private notes by causing DTC to transfer the private notes into the exchange agent’s account at DTC in accordance with the DTC’s procedures for transfer. Delivery of documents to DTC does not constitute delivery to the exchange agent.

      Upon satisfaction of all conditions to the exchange offer, we will accept, promptly after the expiration date, all private notes properly tendered and will issue the exchange notes promptly after acceptance of the private notes.

      For purposes of the exchange offer, we will be deemed to have accepted properly tendered private notes for exchange when we have given oral or written notice of that acceptance to the exchange agent. For each initial note accepted for exchange, you will receive an exchange note having a principal amount equal to that of the surrendered initial note.

      In all cases, we will issue exchange notes for private notes that we have accepted for exchange under the exchange offer only after the exchange agent timely receives:

      If we do not accept any tendered private notes for any reason set forth in the terms of the exchange offer, we will credit the non-exchanged private notes to your account maintained with DTC.

Withdrawal of Tenders

      Except as otherwise provided in this prospectus, you may withdraw tenders of private notes at any time before the exchange offer expires.

      For a withdrawal to be effective, the holder must cause to be transmitted to the exchange agent an agent’s message, which agent’s message must be received by the exchange agent prior to 5:00 p.m., New York City time, on the expiration date. In addition, the exchange agent must receive a timely confirmation of book-entry transfer of the private notes out of the exchange agent’s account at DTC under the procedure for book-entry transfers described in this prospectus along with a properly transmitted agent’s message on or before the expiration date.

      We will determine in our sole discretion all questions as to the validity, form and eligibility, including time of receipt, of notices of withdrawal. Our determination will be final and binding on all parties. Any private notes so withdrawn will be deemed not to have been validly tendered for purposes of the exchange offer, and we will not issue exchange notes with respect to those private notes, unless you validly retender the withdrawn private notes. The private notes will be credited to an account maintained with DTC for the private notes. You may retender properly withdrawn private notes by following one of the procedures described under “— Procedures for Tendering” at any time on or before the expiration date.

Conditions

      Notwithstanding any other term of the exchange offer, we will not be required to accept for exchange, or exchange the exchange notes for, any private notes, and may terminate or amend the exchange offer as provided in this prospectus before the acceptance of the private notes, if, in our reasonable judgment, the

exchange offer violates applicable law, rules or regulations or an applicable interpretation of the staff of the Securities and Exchange Commission or any action or proceeding has been instituted or threatened in any court or before any governmental agency with respect to the exchange offer which, in our judgment, might impair our ability to proceed with the exchange offer or materially and adversely affect us.

      If we determine in our reasonable discretion that any of these conditions are not satisfied, we may:

      If the waiver constitutes a material change to the exchange offer, we will promptly disclose the waiver by means of a prospectus supplement that we will distribute to the registered holders of the private notes, and we will extend the exchange offer for a period of five to ten business days, depending upon the significance of the waiver and the manner of disclosure to the registered holders, if the exchange offer would otherwise expire during the five to ten business day period.

Termination of Rights

      All of your rights under the registration rights agreement will terminate upon consummation of the exchange offer except with respect to our continuing obligations:

Shelf Registration

      If:

we will, at our cost:

      We will provide to each relevant holder copies of the prospectus which is part of the shelf registration statement, notify each holder when the shelf registration statement has been filed and when it has become effective and take certain other actions as are required to permit unrestricted resales of the notes. A holder that sells notes pursuant to the shelf registration statement generally:

      In addition, a holder of private notes will be required to deliver information to be used in connection with the shelf registration statement in order to have the holder’s private notes included in the shelf registration statement. The notes of any holder that unreasonably fails to furnish this information within a reasonable time after receiving the request may be excluded from the shelf registration statement.

Liquidated Damages

      If:

the interest rate borne by the notes will increase by 0.25% per annum during the 90-day period immediately following the occurrence of any of the events described above, each of which will constitute a registration default. The interest rate will increase by 0.25% per annum at the end of each subsequent 90-day period until all such registration defaults have been cured, but in no event shall such rate increase exceed 0.50% per annum. Following the cure of all registration defaults, the accrual of the additional interest will cease and the interest rate will revert to the original rate.

Exchange Agent

      We have appointed Wells Fargo Bank, National Association, as exchange agent for the exchange offer. You should direct any questions and requests for assistance and requests for additional copies of this prospectus to the exchange agent addressed as follows:

Wells Fargo Bank, National Association

707 Wilshire Blvd., 17th Floor

Los Angeles, CA 90071

Attention: Madeline Hall, Corporate Trust Services

Telephone: (213) 614-2588

Facsimile: (213) 614-3355

Fees and Expenses

      We will bear the expenses of soliciting tenders. We are making the principal solicitation by mail; however, our and our affiliates’ officers and regular employees may make additional solicitations by telegraph, telephone or in person.

      We have not retained any dealer manager in connection with the exchange offer and will not make any payments to brokers, dealers or others soliciting acceptances of the exchange offer. We will, however, pay the exchange agent reasonable and customary fees for its services and will reimburse it for its reasonable out-of-pocket expenses.

      We will pay the cash expenses incurred in connection with the exchange offer which we estimate to be approximately $225,000. These expenses include registration fees, fees and expenses of the exchange agent and the trustee, accounting and legal fees and printing costs, among others.

      We will pay all transfer taxes, if any, applicable to the exchange of notes pursuant to the exchange offer. If, however, a transfer tax is imposed for any reason other than the exchange of the private notes pursuant to the exchange offer, then you must pay the amount of these transfer taxes. If you do not submit satisfactory evidence of payment of these taxes or exemption from payment, we will bill the amount of these transfer taxes directly to you.

Consequence of Failures to Exchange

      Participation in the exchange offer is voluntary. We urge you to consult your financial and tax advisors in making your decisions on what action to take.

      Private notes that are not exchanged for exchange notes pursuant to the exchange offer will remain restricted securities. Accordingly, those private notes may be resold only:

      In each case, the private notes may be resold only in accordance with any applicable securities laws of any state of the United States or any other applicable jurisdiction.

Accounting Treatment

      For accounting purposes, we will recognize no gain or loss as a result of the exchange offer. The expenses of the exchange offer will be amortized over the term of the exchange notes.

DESCRIPTION OF EXCHANGE NOTES

      The private notes are governed by, and the exchange notes will be governed by, an indenture dated as of April 12, 2006, between us and Wells Fargo Bank, National Association, as trustee. A copy of the indenture is available to investors in the notes upon request to Allergan, and is available for inspection at the corporate trust office of the trustee.

      The following summary of certain provisions of the indenture does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the notes and the indenture. Because the following is only a summary, it does not contain all information that you may find useful.

      Definitions of certain terms are set forth under “—Certain Definitions” and throughout this description. Capitalized terms that are used but not otherwise defined herein have the meanings assigned to them in the indenture, and those definitions are incorporated herein by reference. As used in this “Description of Notes,” unless otherwise indicated, the words “we,” “us,” “our” and “Allergan” refer to Allergan, Inc., and do not include our subsidiaries. When we refer to “notes” in this section, we mean the private notes, any additional notes issued under the indenture (see “—Additional Notes”) and the exchange notes to be issued in exchange for the private notes and the additional notes, if any, pursuant to the exchange offer.

      The notes will be issued only in registered form in minimum denominations of $2,000 and any integral multiple of $1,000 above that amount. The notes will be payable at the corporate trust office of the paying agent, which initially will be an office or agency of the trustee, or an office or agency maintained by us for such purpose. The notes will be represented by one or more global securities registered in the name of a nominee of the depositary. See “—Book Entry, Delivery and Form.”

      We may, to the extent permitted by applicable law, at any time purchase the notes in the open market or by tender at any price or by private agreement.

Principal, Maturity and Interest

      The notes will initially be limited to $800,000,000 aggregate principal amount and will mature on April 1, 2016, unless earlier redeemed by us (see “—Redemption at the Option of Allergan”). The notes will bear cash interest at the rate of 5.75% per annum from the date of original issuance (April 12, 2006), or from the most recent date interest has been paid or provided for. We pay interest on the notes semiannually in arrears on April 1 and October 1 of each year, commencing on October 1, 2006, to holders of record at the close of business on the March 15 or the September 15 immediately preceding such interest payment date.

      Each payment of cash interest on the notes will include interest accrued for the period commencing on and including the immediately preceding interest payment date (or, if none, the scheduled original issuance date) through the day before the applicable interest payment date. Any payment required to be made on any day that is not a business day will be made on the next succeeding business day and no interest will accrue on such payment for the period from and after such payment date to the date of such payment on the next succeeding business day. Interest will be calculated using a 360-day year composed of twelve 30-day months. A “business day” is any weekday that is not a day on which banking institutions in The City of New York are authorized or obligated to close. Interest will cease to accrue on a note upon its maturity or redemption by us at our option.

Ranking

      The notes are our general obligations and will not be secured by any collateral. Your right to payment under these notes will be:

      As of June 30, 2006, after giving effect to the Financing Transactions, including this offering, and the application of the net proceeds from the Financing Transactions, including the redemption of our 2022 Notes, we and our subsidiaries had approximately $809.0 million of consolidated indebtedness that ranks equally with the notes, and our subsidiaries had approximately $59.0 million of indebtedness that is structurally subordinated to the notes.

Additional Notes

      We may, at any time and from time to time, without the consent of or notice to the holders of the notes create and issue additional notes having the same ranking and the same interest rate, maturity and other terms of the notes offered hereby in all respects (or in all respects except for the payment of interest accruing prior to the issue date of the additional notes or except for the first payment of interest following the issue date of the additional notes) so that the additional notes may be consolidated and form a single series of notes with, and have the same terms as to status, redemption or otherwise as, the notes offered hereby.

      Holders of additional notes would have the right to vote together with holders of notes offered hereby and the exchange notes as one class.

Redemption at the Option of Allergan

      We may redeem the notes, at any time in whole or, from time to time, in part, for cash at a redemption price equal to the greater of:

In each case, accrued and unpaid interest will be paid to the redemption date.

      The term “treasury rate” means, with respect to any redemption date for the notes, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding the redemption date of the comparable treasury issue, assuming a price for the comparable treasury issue (expressed as a percentage of its principal amount)) equal to the comparable treasury price for that redemption date. The treasury rate shall be calculated on the third business day preceding the redemption date.

      The term “comparable treasury issue” means the United States Treasury security selected by the reference treasury dealer as having a maturity comparable to the remaining term of the notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes.

      The term “comparable treasury price” means with respect to any redemption date the reference treasury dealer quotations for that redemption date.

      The term “reference treasury dealer” means Banc of America Securities LLC, Citigroup Global Markets Inc., Morgan Stanley & Co. Incorporated and Goldman, Sachs & Co. and any successor firm; provided that, if any of Banc of America Securities LLC, Citigroup Global Markets Inc., Morgan Stanley & Co. Incorporated or Goldman, Sachs & Co. ceases to be a primary U.S. Government securities dealer, we will substitute another nationally recognized investment banking firm that is a primary U.S. Government securities dealer.

      The term “reference treasury dealer quotations” means, with respect to each reference treasury dealer and any redemption date, the average, as determined by the trustee, of the bid and asked prices for the comparable treasury issue (expressed in each case as a percentage of its principal amount) quoted in writing

to the trustee by such reference treasury dealer at 3:30 p.m., New York City time, on the third business day preceding such redemption date.

      The term “remaining scheduled payments” means the remaining scheduled payments of principal of and interest on the notes that would be due after the related redemption date but for that redemption. If that redemption date is not an interest payment date with respect to the notes, the amount of the next succeeding scheduled interest payment on the notes will be reduced by the amount of interest accrued on the notes to such redemption date.

Certain Covenants Of Allergan

      We will not, and will not permit any of our subsidiaries to, create, assume or suffer to exist any lien on any restricted property to secure any debt of Allergan, any of our subsidiaries or any other person, unless all payments due under the indenture and the notes are secured equally and ratably with such debt for so long as such debt shall be so secured, except for:

      We will not, and will not permit any of our subsidiaries to, enter into any sale and leaseback transaction covering any restricted property unless:

      As used in this section, the following terms have the meanings set forth below:

      The term “consolidated tangible net assets” means the total of the net tangible assets of Allergan and our subsidiaries, included in our financial statements prepared on a consolidated basis in accordance with generally accepted accounting principles, after eliminating all intercompany items.

      The term “restricted property” means (a) any manufacturing facility, or portion thereof, owned or leased by us or any of our subsidiaries and located within the continental United States, which, in the opinion of our board of directors, is of material importance to our business or the business of our subsidiaries taken as a whole, but no such manufacturing facility, or portion thereof, shall be deemed of material importance if its gross book value (before deducting accumulated depreciation) is less than 2% of our consolidated tangible net assets, or (b) any shares of capital stock of any of our subsidiaries owning any such manufacturing facility.

      The term “sale and leaseback transaction” means any arrangement with any person pursuant to which we or any of our subsidiaries leases any restricted property that has been or is to be sold or transferred by us or our subsidiary to such person, other than (1) temporary leases for a term, including renewals at the option of the lessee, of not more than three years, (2) leases between us and our subsidiary or between our subsidiaries, (3) leases of a restricted property executed by the time of, or within 12 months after the latest of, the acquisition, the completion of construction or improvement, or the commencement of commercial operation of the restricted property, and (4) arrangements pursuant to any provision of law with an effect similar to the former Section 168(f)(8) of the Internal Revenue Code of 1954.

      The term “subsidiary” means a corporation of which a majority of the capital stock having voting power under ordinary circumstances to elect a majority of the board of directors of such corporation is owned by (i) us, (ii) us and one or more of our subsidiaries or (iii) one or more of our subsidiaries.

      The term “value” means, with respect to a sale and leaseback transaction, an amount equal to the present value of the lease payments with respect to the term of the lease remaining on the date as of which the amount is being determined, without regard to any renewal or extension options contained in the lease, discounted at the weighted average interest rate on the notes which are outstanding on the effective date of such sale and leaseback transaction and which have the benefit of the indenture.

Merger and Sales of Assets by Allergan

      The indenture provides that we may not consolidate with or merge into any other person or sell, lease, or otherwise transfer (in one transaction or a series of transactions) all or substantially all of the consolidated assets of us and our subsidiaries to any person, unless among other things:

      (2) such person assumes all of our obligations under the notes and the indenture; and

      (3) we or such successor person shall not immediately thereafter be in default under the indenture.

      Upon the assumption of our obligations by such a person in such circumstances, subject to certain exceptions, we shall be discharged from all obligations under the notes and the indenture.

      An assumption of our obligations under the notes and the indenture by such corporation might be deemed for United States federal income tax purposes to be an exchange of the notes for new notes by the holders thereof, resulting in recognition of gain or loss for such purposes and possibly other adverse tax consequences to the holders. Holders should consult their own tax advisors regarding the tax consequences of such an assumption.

      There is no precise, established definition of the phrase “substantially all” under applicable law relating to the transfer of properties and assets under applicable law and accordingly there may be uncertainty as to whether the foregoing provision would apply to a sale or lease of less than all our assets.

Events Of Default

      The indenture provides that, if an event of default specified therein shall have happened and be continuing, either the trustee or the holders of not less than 25% in aggregate principal amount of the notes then outstanding (including exchange notes and additional notes, if any, voting together as a single class) may declare the principal amount of the notes outstanding plus accrued and unpaid interest through but excluding the date of such declaration to be immediately due and payable. In the case of certain events of bankruptcy or insolvency, the principal amount of the notes outstanding plus accrued and unpaid interest through the occurrence of such event shall automatically become and be immediately due and payable.

      Under certain circumstances, the holders of a majority in aggregate principal amount of the outstanding notes (including exchange notes and additional notes, if any, voting together as a single class) may rescind any such acceleration with respect to the notes and its consequences. Interest shall, to the extent permitted by law, accrue and be payable on demand upon a default in the payment of the principal amount or a redemption price on any note, and such interest shall be compounded semi-annually.

      Under the indenture, an event of default is defined as, with respect to the notes, any of the following:

      The occurrence of an event of default may constitute an event of default under our bank credit agreements and other indebtedness in existence from time to time. In addition, the occurrence of certain events of default or an acceleration under the indenture may constitute an event of default under certain of our other indebtedness outstanding from time to time.

      The trustee is required to give notice to holders of the notes of any continuing default known to the trustee within 90 days after the occurrence thereof; provided, that the trustee may withhold such notice, as to any default other than a payment default, if it determines in good faith that withholding the notice is in the interests of the holders.

      The indenture provides that the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of outstanding notes, unless the trustee receives indemnity satisfactory to it against any loss, liability or expense. Subject to certain rights of the trustee, the holders of a majority in aggregate principal amount of the outstanding notes may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee, provided that such direction shall not be in conflict with any law or the indenture and subject to certain other limitations. Before proceeding to exercise any right or power under the indenture at the direction of such holders, the trustee shall be entitled to receive from such holders reasonable security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in complying with any such direction.

      No holder will have any right to pursue any remedy with respect to the indenture or the notes, unless:

      The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. The indenture provides that the trustee may withhold notice to the holders of the notes of any default or event of default other than a payment default, if it determines in good faith that withholding the notice is in the interests of the holders.

Modification And Waiver

      Without the consent of any holder of notes, we and the trustee may amend the indenture to:

      In addition, modification and amendment of the indenture or the notes may be effected by us and the trustee with the consent of the holders of not less than a majority in aggregate principal amount of the notes then outstanding. However, without the consent of each holder affected thereby, no amendment may, among other things:

      The holders of a majority in principal amount of the outstanding notes (including exchange notes and additional notes, if any, voting together as a single class) may, on behalf of the holders of such notes waive any existing or past default under the indenture and its consequences, except a default in the payment of the principal amount, accrued and unpaid interest or redemption price or in respect of any provision which under the indenture cannot be modified or amended without the consent of the holder of each outstanding note affected.

Discharge of the Indenture

      We may satisfy and discharge our obligations under the indenture with respect to the notes by delivering to the trustee for cancellation all outstanding notes or depositing with the trustee, after such outstanding notes have become due and payable, cash sufficient to pay on the maturity date all of the outstanding notes and paying all other sums payable under the indenture with respect to the notes.

Book Entry, Delivery and Form

      The private notes are represented by, and the exchange notes will be represented by, one or more permanent global notes in definitive, fully registered form without interest coupons (the “Global Notes”), deposited with the trustee as custodian for, and vested in the name of, DTC or its nominee (such nominee referred to herein as the “Global Note Holder”).

Depository Procedures

      The following description of the operations and procedures of DTC, Euroclear and Clearstream are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. We take no responsibility for these operations and procedures and urge investors to contact the system or their participants directly to discuss these matters.

      DTC has advised us that it is a limited-purpose trust company which was created to hold securities for its participating organizations (collectively, the “participants”) and to facilitate the clearance and settlement of transactions in such securities between participants through electronic book-entry changes in accounts of its participants. DTC’s participants include securities brokers and dealers (including the initial purchasers), banks and trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies (collectively, the “indirect participants”) that clear through or maintain a custodial relationship with a participant, either directly or indirectly. Persons who are not participants may beneficially own securities held by or on behalf of DTC only through DTC’s participants or DTC’s indirect participants.

      We expect that pursuant to procedures established by DTC (i) upon the issuance of the notes, DTC or its custodian will credit, on its internal system, the principal amount at maturity of the individual beneficial interests represented by such notes to the respective accounts of persons who have accounts with such depositary and (ii) ownership of the notes will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC (with respect to the interests of DTC’s participants), DTC’s participants and DTC’s indirect participants. Prospective purchasers are advised that the laws of some states require that certain persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer notes will be limited to such extent.

      So long as DTC, or its nominee, is the registered owner or holder of the notes, DTC or that nominee, as the case may be, will be considered the sole owner or holder of the notes represented by the Global Note for all purposes under the indenture and the notes. No beneficial owner of an interest in a Global Note will be able to transfer that interest except in accordance with DTC’s applicable procedures, in addition to those provided for under the indenture and, if applicable, those of Euroclear and Clearstream Banking.

      Payments of the principal of, and interest on, a Global Note will be made to the Global Note Holder as the registered owner thereof. Neither we, the trustee nor any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

      We expect that the Global Note Holder, upon receipt of any payment of principal or interest in respect of a Global Note, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such Global Note as shown on the records of the Global Note Holder. We also expect that payments by participants to owners of beneficial interests in such Global Note held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants.

      Transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds. Transfers between participants in Euroclear and Clearstream Banking will be effected in the ordinary way in accordance with their respective rules and operating procedures.

      Subject to compliance with the transfer restrictions applicable to the notes, cross-market transfers between the participants in DTC, on the one hand, and Euroclear or Clearstream Banking, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream Banking,

as the case may be, by its respective depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream Banking, as the case may be, by the counterparts in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream Banking, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream Banking participants may not deliver instructions directly to the depositories for Euroclear or Clearstream Banking.

      Because of time zone differences, the securities account of a Euroclear or Clearstream Banking participant purchasing an interest in a Global Note from a participant in DTC will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream Banking participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream Banking) immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream Banking as a result of sales of interest in a Global Note by or through a Euroclear or Clearstream Banking participant to a participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream Banking cash account only as of the business day for Euroclear or Clearstream Banking following DTC’s settlement date.

      We expect that DTC will take any action permitted to be taken by a holder of notes (including the presentation of notes for exchange as described below) only at the direction of one or more participants to whose account DTC’s interests in a Global Note is credited and only in respect of such portion of the aggregate principal amount of notes as to which such participant or participants has or have given such direction. However, if there is an Event of Default under the notes, the DTC will exchange the applicable Global Note for certificated notes, which it will distribute to its participants.

      If DTC is at any time unwilling or unable to continue as a depositary for the Global Notes and a successor depositary is not appointed by us within 90 days, we will issue certificated notes in exchange for the Global Notes. Holders of an interest in a Global Note may receive certificated notes in accordance with DTC’s rules and procedures in addition to those provided for under the indenture.

Same-Day Settlement and Payment

      The indenture requires that payments in respect of the notes (including principal, premium, if any, and interest) be made by wire transfer of immediately available funds to the accounts specified by the Global Note Holders.

Transfer and Exchange

      A holder may transfer or exchange the notes in accordance with the procedures set forth in the indenture. The registrar may require a holder, among other things, to furnish appropriate endorsements and transfer documents, and to pay any taxes and fees required by law or permitted by the indenture. The registrar is not required to transfer or exchange any note selected for redemption.

      The registered holder of a note will be treated as the owner of it for all purposes.

Governing Law

      The indenture, the notes and the registration rights agreement will be governed by and construed in accordance with the laws of the State of New York.

Information Concerning the Trustee

      Wells Fargo Bank, National Association, an affiliate of an initial purchaser of the Convertible Notes, is the trustee, registrar and paying agent under the indenture. We may maintain deposit accounts and conduct other banking transactions with the trustee in the normal course of business.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

      The following is a summary of certain material United States federal income tax considerations relating to the exchange of private notes for exchange notes pursuant to this exchange offer, but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed, possibly retroactively, so as to result in United States federal income tax consequences different from those set forth below. We have not sought any ruling from the Internal Revenue Service (“IRS”) with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions.

      This summary is limited to holders who purchased the notes upon their initial issuance at their initial issue price and who hold the notes as capital assets. This summary also does not address the effect of the United States federal estate or gift tax laws or the tax considerations arising under the laws of any foreign, state or local jurisdiction. In addition, this discussion does not address tax considerations applicable to an investor’s particular circumstances or to investors that may be subject to special tax rules, including, without limitation:

      YOU ARE URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE APPLICATION OF THE UNITED STATES FEDERAL INCOME TAX LAWS TO YOUR PARTICULAR SITUATION AS WELL AS ANY TAX CONSEQUENCES OF THE EXCHANGE OFFER ARISING UNDER THE FEDERAL ESTATE OR GIFT TAX RULES OR UNDER THE LAWS OF ANY STATE, LOCAL, FOREIGN OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

Exchange of Private Notes for Exchange Notes

      The exchange of private notes for exchange notes in the exchange offer will not be treated as an “exchange” for federal income tax purposes because the exchange notes will not be considered to differ materially in kind or extent from the private notes. Accordingly, the exchange of private notes for exchange notes will not be a taxable event to holders for federal income tax purposes. Moreover, the exchange notes will have the same tax attributes as the private notes and the same tax consequences to holders as the private notes have to holders, including without limitation, the same adjusted tax basis and holding period. Therefore, references to “notes” apply equally to the exchange notes and the private notes.

PLAN OF DISTRIBUTION

      Each broker-dealer that receives exchange notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such exchange notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of exchange notes received in exchange for private notes where such private notes were acquired as a result of market-making activities or other trading activities. We have agreed that, starting on the expiration of the exchange offer and ending on the close of business one year after the expiration of the exchange offer, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

      We will not receive any proceeds from any sale of exchange notes by brokers-dealers. Exchange notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the exchange notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such exchange notes. Any broker-dealer that resales exchange notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such exchange notes may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit of any such resale of exchange notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. By acknowledging that it will deliver and by delivering a prospectus, a broker-dealer is not deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

      For a period of one year after the expiration of the exchange offer, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents. We have agreed to pay all expenses incident to the exchange offer (including the expenses of one counsel for the holder of the securities) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the securities (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

      The broker-dealer acknowledges and agrees that, upon receipt of notice from us of the happening of any event which:

      which notice we agree to deliver promptly to the broker-dealer, the broker-dealer will suspend use of this prospectus until we have notified the broker-dealer that delivery of the prospectus may resume and have furnished copies of any amendment or supplement to this prospectus to the broker-dealer.

      Each holder who wishes to exchange its notes for exchange notes pursuant to the exchange offer will be deemed to have represented that, at the time of the consummation of the exchange offer:
