described in Item 6.



Item 4.  Purpose of the Transaction.
         ---------------------------

         The purpose of the proposed transactions is to sell 8,680,000 of Mr.
Ajnsztajn's shares of common stock of the Issuer, and to transfer his rights
under the Stockholders Agreement, as described in Item 6 below, to nominate one
director of the Issuer.

         Except as set forth in this statement, as of the date of the filing of
this statement, Mr. Ajnsztajn does not have any other plan or proposal which
relates to or would result in any of the actions specified in subparagraphs (a)
through (j) of Item 4 of Schedule 13D.



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

         Item 6 is supplemented to include the following:

         On December 29, 2004, Mr. Ajnsztajn, Gaston Liebhaber ("Mr. Liebhaber")
and SkyePharma, SkyePharma, Ltd. ("SkyePharma") executed a Stock Purchase
Agreement (the "Stock Purchase Agreement") and an Assignment Agreement (the
"Assignment Agreement").

         Mr. Ajnsztajn is the former Chief Executive Officer and former member
of the Board of Directors of the Issuer. Mr. Liebhaber is a former member of the
Board of Directors of the Issuer.

         Pursuant to the Stock Purchase Agreement, SkyePharma has agreed to
purchase 8,680,000 shares of common stock of the Issuer owned by Mr. Ajnsztajn
and 2,480,000 shares of common stock of the Issuer owned by Mr. Liebhaber. The
purchase price to be paid by SkyePharma for Mr. Ajnsztajn's shares will be
4,263,963 SkyePharma ordinary shares. The purchase price to be paid by
SkyePharma for Mr. Liebhaber's shares will be 1,218,275 SkyePharma ordinary
shares. The share purchase is conditioned upon, among other closing conditions,
the valid appointment of the additional SkyePharma Directors pursuant to the
Assignment Agreement, which condition may be waived at SkyePharma's sole
discretion.

         If a purchase is consummated pursuant to the Stock Purchase Agreement,
Mr. Ajnsztajn will no longer own shares of the Issuer's common stock.

         Pursuant to the Assignment Agreement, each of Mr. Ajnsztajn and Mr.
Liebhaber agreed to assign his respective rights under Article II of the
Stockholders Agreement, dated December 10, 2001, as amended on January 20, 2004,
between the Issuer, Mr. Ajnsztajn, Mr. Liebhaber, SkyePharma and the other
parties thereto (the "Stockholders Agreement"), including his rights under
Section 2.1 and 2.2 of the Stockholders Agreement to nominate and designate
Directors, to SkyePharma. Each of Mr. Ajnsztajn and Mr. Liebhaber has the right,
among other things, to appoint one director to the Board of Directors of the
Issuer under the Stockholders Agreement. The Assignment Agreement provides that,
upon the valid appointment of two Directors nominated by SkyePharma to the Board
of Directors of the Issuer and the satisfaction of the other conditions listed
therein, SkyePharma shall be obligated to issue to Mr. Ajnsztajn 426,396
SkyePharma ordinary shares and to Mr. Liebhaber 121,827 SkyePharma ordinary
shares.
