Purpose of Transaction. On October 10, 2003, Bayer Corporation's (the "Company") representative on the Issuer's board of directors resigned as a director. Pursuant to the Common Stock Purchase Agreement dated April 23, 2001 between the Company and the Issuer, as amended April 30, 2003 (the "Agreement"), the Company is entitled to designate a new nominee for election by the board of directors to serve until the immediately succeeding annual meeting of shareholders. The Company has advised the Issuer that it does not currently plan to make such a designation. Such a decision, however, does not constitute a waiver of the Company's rights to so designate in the future prior to the next meeting of shareholders at which directors will be elected, nor does it preclude the Company from exercising its rights under the Agreement to designate a director nominee in connection with the Issuer's next meeting of shareholders at which directors will be elected. CUSIP No. 71713J107 Page 6 of 6 Pages Signature After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this amendment to this statement is true and correct.
