have the meanings set forth in the Reporting Persons' Schedule 13D (Amendment
No. 1).

Item 4.           Purpose of Transaction

         The information appearing in this Item is hereby amended by the
addition of the following information:

         In connection with the Company's filing of Amendment No. 2 to the Shelf
         F-3 (as defined in Reporting Persons' Schedule 13D (Amendment No. 4),
         Coomber determined that it would not effect forward sale transactions
         as described in the Reporting Persons' Schedule 13D (Amendment No. 4)
         pursuant to the Shelf F-3. Coomber has registered 2,100,000 shares
         pursuant to the Company's Shelf F-3, which it may sell from time to
         time in accordance with the Plan of Distribution described therein.
         Coomber may also effect forward sale transactions up to a maximum of
         4,000,000 shares (including the forward sales transactions described in
         Item 5 below) in reliance on the exemption from registration provided
         by Rule 144 under the Securities Act of 1933, as amended, and existing
         no-action positions of the staff of the Securities and Exchange
         Commission.

Item 5.           Interest in Securities of the Issuer

         The information set forth in this Item is hereby amended by the
addition of the following information:

         Of the 8,601,550 shares of Common Stock beneficially owned by the
         Reporting Persons, Coomber has granted a security interest in 4,000,000
         shares to Merrill Lynch in connection with the forward sale agreements
         described in Item 6 of this Schedule 13D (Amendment No. 4). Upon
         settlement of each such forward sale transaction, Coomber may deliver
         up to a total of such 4,000,000 shares of Common Stock in satisfaction
         of Coomber's obligations under the forward sale agreements. The
         Reporting Persons will generally continue to have sole voting rights
         with respect to the pledged shares during the term of the


         forward sale. However, Merrill Lynch may borrow the pledged shares from
         Coomber in connection with Merrill Lynch's hedging of its exposure
         under the forward sale agreements. Coomber will temporarily cease to
         have voting rights with respect to any Common Stock borrowed by Merrill
         Lynch but will reacquire such voting rights when Merrill Lynch returns
         the borrowed shares to Coomber.

         Through the date of this Schedule 13D (Amendment No. 5), Coomber has
         entered into forward sale transactions with Merrill Lynch with respect
         to an aggregate of 1,900,000 shares, and received aggregate net
         proceeds of approximately $46.94 million. If Coomber elects to settle
         all forward sale transactions effected to date by delivery of Common
         Stock, the Reporting Persons would beneficially own 6,701,550 shares of
         Common Stock, or approximately 19% of the Company's Common Stock. If
         Coomber were to dispose of 4,000,000 shares of Common Stock through a
         combination of forward sale transactions and sales of Common Stock
         pursuant to the Shelf F-3 after it is declared effective, the Reporting
         Persons would beneficially own 4,601,550 shares of Common Stock, or
         approximately 13% of the Company's Common Stock.

         Each of the Reporting Individuals disclaims any beneficial interest in
         the CYI shares reported in this Schedule 13D.

         Except for the forward sale transaction described herein, none of the
         Reporting Persons and, to their knowledge, none of the persons listed
         in Item 2 of Schedule 13D (Amendment No. 1) has effected any
         transactions in the Company's Common Stock in the 60 days preceding the
         filing of this Schedule 13D (Amendment No. 5).


                                   SIGNATURES

         After reasonable inquiry and to the best of his or her knowledge and
belief, each of the undersigned certifies that the information in this statement
is true, complete and correct.
