Item 3. Source and Amount of Funds or Other Consideration.

     WPV had held 5,609,524 shares of Common Stock, par value $0.001 per share
of Skillsoft Corporation, ("SkillSoft") a Delaware corporation (the "Skillsoft
Common Stock"). The shares of Skillsoft Common Stock held by WPV were exchanged
for 13,279,987 SmartForce ADSs pursuant to an Agreement and Plan of Merger (the
"Merger Agreement"), dated as of June 10, 2002, by and among the Company, Slate
Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of the
Company and SkillSoft, pursuant to which Slate Acquisition Corp. agreed to merge
with and into SkillSoft (the "Merger"), with SkillSoft remaining as the
surviving corporation and a wholly owned subsidiary of the Company.

Item 4. Purpose of Transaction.

     The Merger was consummated on September 6, 2002. The Merger Agreement
provided that, as a result of the Merger, each outstanding share of SkillSoft
Common Stock was converted into the right to receive 2.3674 SmartForce ADSs (the
"Exchange Ratio"). Pursuant to the terms of the Merger Agreement, no fractional
shares of SmartForce ADSs were issued in the Merger, and each stockholder of
SkillSoft who would otherwise have been entitled to receive a fractional share
of SmartForce ADSs instead received a cash amount equal to such fractional part
of a SmartForce ADS multiplied by the weighted average of the last reported
sales prices of SmartForce ADSs at 4:00 p.m., Eastern time, end of regular
trading hours on The Nasdaq National Market during the ten consecutive trading
days ending on and including the last trading day prior to the effective time of
the Merger.

     In consideration of the Company's entering into the Merger Agreement,
certain

                                      -6-



stockholders of SkillSoft, including WPV, entered into the SkillSoft Stockholder
Voting Agreement, dated as of June 10, 2002, with the Company and SkillSoft (the
"SkillSoft Voting Agreement"). Pursuant the SkillSoft Voting Agreement, WPV
agreed to vote an aggregate of 5,609,524 shares of SkillSoft Common Stock in
favor of the Merger and on related matters. In connection with the SkillSoft
Voting Agreement, the Company was granted an irrevocable proxy to vote these
shares of SkillSoft Common Stock in favor of the Merger and on related matters.

     Pursuant to the Merger Agreement, the Company agreed to take all necessary
action to cause, effective as of the effective time of the Merger, among other
changes to the board of directors and management of the Company, the election of
Stewart K.P. Gross, who had been a director of SkillSoft, to the board of
directors of the Company. Mr. Gross is a partner of WP and is a Senior Managing
Director and member of WP LLC.

     The Reporting Persons believe that the transaction described herein is
attractive based on the Company's business prospects and strategy. Depending on
prevailing market, economic and other conditions, the Reporting Persons may from
time to time acquire additional securities of the Company, engage in discussions
with the Company concerning further acquisitions of securities of the Company or
otherwise invest in the Company or one or more of its subsidiaries. The
Reporting Persons intend to review their investment in the Company on a
continuing basis and, depending upon the price and availability of the Company's
securities, subsequent developments concerning the Company, the Company's
business and prospects, other investment and business opportunities available to
the Reporting Persons, general stock market and economic

                                      -7-



conditions, tax considerations and other factors considered relevant, may decide
at any time to increase or decrease the size of their investment in the Company
or to sell any or all of the securities of the Company that they hold.

     Other than as set forth above, none of the Reporting Persons has any
present plans or proposals which relate to or would result in any transaction,
change or event specified in clauses (a) through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

     (a) Due to their respective relationships with each other, each of the
Reporting Persons may be deemed to beneficially own an aggregate of 13,279,987
SmartForce ADSs as of September 16, 2002, by virtue of WPV's ownership of such
shares as of such date. The 13,279,987 SmartForce ADSs which the Reporting
Persons may be deemed to beneficially own represent approximately 13.38% of the
99,261,944 shares of SmartForce ADSs outstanding as of September 6, 2002 (based
on (i) the Company's Quarterly Report on Form 10-Q for the quarter ended June
30, 2002 disclosing that 57,434,679 SmartForce ADSs were outstanding, (ii)
SkillSoft's Quarterly Report on Form 10-Q for the quarter ended July 31, 2002
disclosing that 7,668,018 shares of SkillSoft Common Stock were outstanding and
(iii) the application of the exchange ratio of 2.3674 to determine that
41,927,265 SmartForce ADSs were issued pursuant to the Merger.)

     (b) WP shares the power to vote or to direct the vote and to dispose or to
direct the disposition of the 13,279,987 it may be deemed to beneficially own as
of September 16, 2002. Each of the Reporting Persons shares the power to vote or
to direct the vote and to dispose or to direct the disposition of the 13,279,987
shares of Common Stock it may be deemed to beneficially own as of September 16,
2002.

                                      -8-



     (c) Except for the transaction described in Items 3 and 4 and this Item 5,
no transactions in SmartForce ADS were effected during the last sixty days by
the Reporting Persons or any of the persons set forth on Schedules I or in Item
2(d) hereto.

     (d) Except as set forth in this Item 5, no person other than each
respective record owner referred to herein of SmartForce ADSs is known to have
the right to receive or the power to direct the receipt of dividends from, or
the proceeds from the sale of, such SmartForce ADSs.

     (e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to
        the Securities of the Issuer.

     The description of the SkillSoft Voting Agreement, the Merger Agreement and
the Merger in Item 4 above are incorporated herein by reference. The foregoing
descriptions are qualified in there entirety by references to each agreement,
which are Exhibit 2 and Exhibit 1, respectively to this Schedule 13D.

     In addition, WPV, entered into the Registration Rights Agreement, dated as
of June 10, 2002, with the Company (the "Registration Rights Agreement"). The
Registration Rights Agreement provides that, under certain circumstances, the
Company will register the SmartForce ADSs issued to WPV and any partner of WPV
in connection with the Merger on a registration statement in compliance with the
Securities Act of 1933, as amended. The foregoing summary is qualified in its
entirety by reference to Registration Rights Agreement, Exhibit 4 to this
Schedule 13D and incorporated in this Schedule 13D by reference.

                                      -9-



     Other than the Registration Rights Agreement, the SkillSoft Voting
Agreement, the Merger Agreement and the Merger, to the best knowledge of
SkillSoft, there are no contracts, arrangements, understandings or relationships
(legal or otherwise) among the persons or entities listed in Item 2 and between
such person or entity and any person or entity with respect to any securities of
the Issuer, including but not limited to transfer of voting of any of the
