          Item  4  is  hereby   amended  by  adding  the  following   after  the

          On July 27, 2006, Laddcap submitted to the Company its written consent
to  action  without  a  meeting  pursuant  to  Section  228(a)  of  the  General

following  actions,  set forth in the proposals below,  without a meeting of the
stockholders of the Company:

               1. The removal without cause of M.S. Koly,  Samuel  Herschkowitz,
          M.D.,  Mark  A.  Corigliano,  Daniel  Isdaner  and  Victor  Nevins  as
          directors of the Company and any other  person or persons  (other than
          the  persons  elected  pursuant  to this  proposed  action by  written
          consent) elected or appointed to the Board of Directors of the Company
          prior to the effectiveness of these proposals;

               2. The election of the following five persons as directors of the
          Company to fill the vacancies  resulting  from proposal 1: Jonathan A.
          Foltz,  Michael Karpf,  M.D.,  Robert B. Ladd, Paul William  Frederick
          Nicholls and Fred S. Zeidman; and

               3. The  repeal  of each  provision  of the  Company's  Bylaws  or
          amendments of the Bylaws that are adopted after  December 31, 2005 and
          before the effectiveness of the foregoing two proposals.

          Pursuant to Section 213(b) of the General Corporation Law of the State
of  Delaware,  the record date for this consent  solicitation  shall be July 27,
2006 (the "Record Date").  Laddcap intends, in accordance with Regulation 14A of
the Securities Exchange Act of 1934, as amended, to solicit the written consents
of all the Company's stockholders,  entitled to deliver a written consent, as of
the Record Date.

Mr. Ladd  possesses  the sole  power  to vote and the sole  power to direct  the
disposition of all  securities of the Company held by Laddcap.  Thus, as of July

event that  required the filing by Mr. Ladd of Amendment  No. 10 to the Schedule
13D with respect to the Company:

or securities  convertible into,  exercisable for or exchangeable for Shares, by
Mr. Ladd or any other person or entity controlled by him or any person or entity
