         This Amendment No. 3 (the "Amendment") hereby amends the initial
Schedule 13D filed on July 10, 1998, Amendment No. 1 to the initial Schedule 13D
filed on April 22, 1999 and Amendment No. 2 to the initial Schedule 13D filed on

defined in the initial Schedule 13D, Amendment No. 1 to the initial Schedule 13D
and Amendment No. 2 to the initial Schedule 13D. Except as specifically provided
herein, this Amendment does not modify any of the information previously

Item 5.  Interest in Securities of the Issuer.
         ------------------------------------

         (a), (b) Pursuant to the Amended and Restated Existing Assets
Management Agreement dated September 30, 2001, under which Charlesbank serves as
investment manager to Harvard and its affiliates, including Aeneas Venture
Corporation ("Aeneas"), Charlesbank is the beneficial owner of 2,675,456 shares
of Common Stock of the Issuer (approximately 11.5% of the shares of Common Stock
based on the most recent filing of the Issuer with the SEC). The sole purpose of
this filing is to reflect a decrease in the percentage of shares of Common Stock
of the Issuer owned by Charlesbank.

         Charlesbank has sole power to vote and sole power to dispose of such
shares to which this Amendment relates.

         (c) Between December 28, 2001 and January 2, 2002, and on behalf of
Aeneas, Charlesbank bought and sold shares of Common Stock of the Issuer in
open-market transactions on the New York Stock Exchange. The transaction dates,
number of shares bought and sold and prices per share during that period are set
forth on Exhibit A hereto.

         (d) Not applicable.
