This Amendment No. 6 to Schedule 13D relates to the common stock, $0.01 par value per share (the “Common Stock”), of Fisher Scientific International Inc., a Delaware corporation (the “Company”), and supplements the information set forth in the Schedule 13D, as amended by Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4, and Amendment No. 5 thereto, filed jointly on behalf of the following persons (collectively, the “Reporting Persons”) on February 3, 1998, April 13, 1999, July 3, 2001, April 29, 2002, November 15, 2002, and March 7, 2003, respectively: (1) Thomas H. Lee Equity Fund III, L.P., a Delaware limited partnership (“Equity Fund III”), (2) Thomas H. Lee Foreign Fund III, L.P., a Delaware limited partnership (“Foreign Fund III”), (3) THL FSI Equity Investors, L.P., a Delaware limited partnership (“THL FSI”), (4) Thomas H. Lee Investors Limited Partnership, a Massachusetts limited partnership (formerly THL-CCI  Limited Partnership), (5) Thomas H. Lee Equity Advisors III Limited Partnership, a Massachusetts limited partnership (“Advisors III”), (6) THL Equity Trust III, a Massachusetts business trust (“Trust III”), (7) THL Investment Management Corp., a Massachusetts corporation (“THL Investment”), and (8) certain persons affiliated with The Thomas H. Lee Company, a Massachusetts sole proprietorship, and listed on Schedule I attached hereto (the “Additional THL Persons” and collectively with Equity Fund III, Foreign Fund III, THL FSI and Thomas H. Lee Investors Limited Partnership, the “THL Entities”).
On April 8, 2003 Equity Fund III, L.P., Foreign Fund III, L.P., and THL FSI made pro rata distributions to their respective partners of the Common Stock of the Company held by each of them.  Immediately subsequent to these distributions, Advisors III, the general partner of Equity Fund III, L.P., Foreign Fund III, L.P., and THL FSI, likewise made a pro rata distribution to its partners of the Common Stock of the Company that it received in the initial distributions.  Certain of the Additional THL Persons, as members of Advisors III, received shares as part of the distribution by Advisors III.
Item 5.	Interest in Securities of the Issuer
Items 5(a) and (b) are hereby amended and replaced in their entirety with the following:
The Reporting Persons may together constitute a “group” within the meaning of Rule 13d-5(b) under the Exchange Act. As a member of a group, each Reporting Person may be deemed to beneficially own the shares of Common Stock beneficially owned by the members of the group as a whole (collectively, the “THL Shares”). Each of the Reporting Persons expressly disclaims beneficial ownership of those THL Shares held by any other members of such group.
Equity Fund III has indirect beneficial ownership of 991,340 shares of Common Stock pursuant to warrants (the “Warrants”) issued under a Warrant Acquisition Agreement, dated as of January 21, 1998 (the “Warrant Acquisition Agreement”). Assuming Equity Fund III’s exercise of the Warrants, Equity Fund III has beneficial ownership of approximately 1.8% of the Common Stock outstanding as of May 13, 2003 (the “Outstanding Shares”). Equity Fund III has shared voting and shared dispositive power with respect to such shares of Common Stock.
Foreign Fund III has indirect beneficial ownership of 61,340 shares Common stock pursuant to Warrants issued under the Warrant Acquisition Agreement. Assuming Foreign Fund III’s exercise of the Warrants, Foreign Fund III has beneficial ownership of less than 1% of the Outstanding Shares. Foreign Fund III has shared voting and shared dispositive power with respect to such shares of Common Stock.
THL FSI has indirect beneficial ownership of 498,070 shares of Common Stock pursuant to Warrants issued under the Warrant Acquisition Agreement. Assuming THL FSI’s exercise of the Warrants, THL FSI has beneficial ownership of less than 1% of the Outstanding Shares. THL FSI has shared voting and shared dispositive power with respect to such Shares.
Advisors III, as sole general partner of Equity Fund III, Foreign Fund III and THL FSI, and Trust III, as sole general partner of Advisors III, may be deemed to have indirect beneficial ownership of 1,550,750 shares of Common Stock pursuant to Warrants issued under the Warrant Agreement to Equity

Fund III, Foreign Fund III and THL FSI, which represents approximately 2.83% of the Outstanding Shares. The filing of this Schedule 13D by Advisors III and Trust III shall not be construed as an admission that Advisors III or Trust III is, for the purpose of Section 13(d) of the Exchange Act, the beneficial owner of shares of Common Stock held by Equity Fund III, Foreign Fund III and THL FSI.

Thomas H. Lee Investors Limited Partnership has indirect beneficial ownership of 61,045 shares of Common Stock pursuant to Warrants issued under the Warrant Acquisition agreement. Assuming its exercise of the Warrants, Thomas H. Lee Investors Limited Partnership has beneficial ownership of less than 1% of the Outstanding Shares. Thomas H. Lee Investors Limited Partnership has sole voting and sole dispositive power with respect to such shares of Common Stock.

THL Investment, as sole general partner of Thomas H. Lee Investors Limited Partnership, and Thomas H. Lee, as chief executive officer and sole director of THL Investment, may be deemed indirect beneficial owners of 61,045 shares of Common Stock pursuant to Warrants issued under the Warrant Agreement, which are beneficially owned by Thomas H. Lee Investors Limited Partnership, which represents less than 1% of the Outstanding Shares. The filing of this Schedule 13D by THL Investment and Mr. Lee shall not be construed as an admission that THL Investment or Mr. Lee is, for the purpose of Section 13(d) of the Exchange Act, the beneficial owner of shares of Common Stock held by Thomas H. Lee Investors Limited Partnership.

Each of the Additional THL Persons has both direct and indirect beneficial ownership of less than 1% of the Outstanding Shares. Each of the Additional THL Persons has sole voting and sole dispositive power with respect to such shares of Common Stock. David V. Harkins may be deemed to share voting and dispositive power over shares of Common Stock held by the 1995 Harkins Gift Trust. The filing of this Schedule 13D shall not be construed as an admission that Mr. Harkins is, for the purpose of Section 13 (d) of the Exchange Act, the beneficial owner of such shares of Common Stock. Scott M. Sperling may be deemed to share voting and dispositive power over shares of Common Stock held by the Sperling Family Limited Partnership. The filing of this Schedule 13D shall not be construed as an admission that Mr. Sperling is, for the purpose of Section 13(d) of the Exchange Act, the beneficial owner of such shares of Common Stock.

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that a Reporting Person is the beneficial owner of any of the shares of Common Stock.
