This Agreement shall be effective as of January 1, 2002.

2. Options.

You shall be granted an option or options (the "Options") to purchase 150,000 shares of the Company's common stock at an exercise price equal to the closing price of the Company's common stock on March 8, 2002. The Options shall be exercisable for a period of five years and shall vest as follows: 50,000 Options shall vest and become exercisable on each six month anniversary of March 8, 2002, commencing on September 8, 2002; provided, that (A) if you are replaced or asked to resign as Chairman of the Executive Committee of the Board of Directors all of the Options not previously vested shall vest in full and be immediately exercisable on the date on which you are replaced or asked to resign, as the case may be, or (B) in the event of a Transaction (as defined in the October Agreement), all of the Options not previously vested shall vest in full and be immediately exercisable on the date immediately prior to the closing of such Transaction so that you may elect to participate in the Transaction.

You hereby covenant and agree that you shall be solely responsible for all such taxes, withholding and similar items (both employee and employer portions) with respect to all fees paid by the Company to you under this Agreement, and to indemnify and hold the Company harmless with respect to such taxes and withholding. You shall not be eligible for, nor shall you participate in, nor shall you be entitled to compensation in lieu of any insurance, benefit, retirement or other plan or program provided by the Company to its employees.

This Agreement will terminate on three months' written notice of termination from either party ; provided that written notice by you to the Chairman of the Board of Directors shall constitute notice to the Company.
