societe anonyme organized under the laws of France (the "Parent"), and
FINANCIERE DE VIDEOCOMMUNICATION, a societe anonyme organized under the laws of
France and an indirect wholly owned subsidiary of Parent (the "Seller").

         WHEREAS, the Company and Parent entered into an Investment Agreement,
dated as of December 14, 2001 ("Investment Agreement"), pursuant to which the
Parent purchased from the Company 5,760,479 shares (the "Preferred Shares") of
Series D Mandatorily Convertible Participating Preferred Stock, par value $0.01
per share (the "Preferred Stock"), of the Company;

         WHEREAS, the Company and Parent also entered into a Contingent Value
Rights Agreement, dated as of January 22, 2002 ("CVR Agreement"), pursuant to
which the Company issued and delivered to the Parent contingent value rights
("CVRs"); and

         WHEREAS, the Seller now desires, on behalf of and for the sole benefit
of Parent, to sell and the Purchaser desires to purchase the Shares;

         NOW, THEREFORE, in consideration of the foregoing, the parties hereby
covenant and agree as follows:

Company, the 57,604,790 shares of Common Stock (the "Shares") into which the
Preferred Shares shall have converted automatically immediately prior to the

"Closing Date").

         Section 1.3 Delivery and Payment. On the Closing Date, the Seller shall
deliver to the Company the certificate representing the Preferred Shares,
