If Stockholder acquires Securities after the date hereof, Stockholder shall tender (or cause the record holder to tender) such Securities on or before such fifth business day or, if later, on or before the second business day after such acquisition. Stockholder hereby acknowledges and agrees that Parent's and Purchaser's obligation to accept for payment, purchase and pay for the Securities in the Offer, including the Securities Beneficially Owned by Stockholder, is subject to the terms and conditions of the Offer. (b) Stockholder hereby permits Parent and Purchaser to publish and disclose in the Offer Documents and, if approval of the Merger by the Company's stockholders is required under applicable law, the Proxy Statement (including all documents and schedules filed with the SEC) Stockholder's identity and ownership of the Securities and the nature of Stockholder's commitments, arrangements and understandings under this Agreement; provided that Stockholder shall have a right to review and comment on such disclosure a reasonable time before it is publicly disclosed. 3. OPTION. (a) In order to induce Parent and Purchaser to enter into the Merger Agreement, Stockholder hereby grants to Purchaser an irrevocable option (a "SECURITIES OPTION") to purchase the Securities (the "OPTION SECURITIES") at the Offer Price, subject to increase as set forth below (the "PURCHASE PRICE"). The Securities Option may be exercised, in whole but not in part, by written notice to Stockholder (as set forth below), for a period of ten (10) business days (the "10 DAY PERIOD") following termination of the Merger Agreement or termination of the Offer, whichever shall first occur; PROVIDED that, prior to such termination, either (i) a Trigger Event shall have occurred or (ii) (A) the Company shall have received a written proposal from any 2 person other than Parent, Purchaser or any affiliate of Parent or Purchaser for an Acquisition Transaction, which proposal shall not have expired or been withdrawn, (B) the Merger Agreement shall have been terminated by Parent pursuant to Section 8.01(b), 8.01(d)(ii), 8.01(f) or 8.01(g) and (C) at the time of such termination the Minimum Condition shall not have been satisfied. Notwithstanding the foregoing, the Securities Option may not be exercised until: (i) all waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR ACT"), required for the purchase of the Securities upon such exercise shall have expired or been waived and any other conditions under the other Antitrust Laws shall have been satisfied and (ii) there shall not be in effect any preliminary injunction or other order issued by any Governmental Entity prohibiting the exercise of the Securities Option pursuant to this Agreement; provided that if (i) all HSR Act waiting periods shall not have expired or been terminated or (ii) there shall be in effect any such injunction or order, in each case on the expiration of the 10 Day Period, the 10 Day Period shall be extended until five (5) business days after the later of (A) the date of expiration or termination of all HSR Act waiting periods, and (B) the date of removal or lifting of such injunction or order. (b) In the event that Purchaser wishes to exercise the Securities Option, Purchaser shall send a written notice (the "NOTICE") to Stockholder identifying the date (not less than two (2) nor more than five (5) business days from the date of the Notice) for the closing of such purchase, which closing shall be held at the executive offices of the Company (or such other place as the parties may agree). At the closing, Stockholder shall deliver to Purchaser appropriate and effective instruments of transfer of the Option Securities, against payment to Stockholder of the Purchase Price, in same day funds, by wire transfer to such account as Stockholder shall designate. (c) In the event the Option Securities are acquired by Purchaser pursuant to the exercise of the Securities Option (the "ACQUIRED SECURITIES") and, either before or at any time within the one-year period following such acquisition, Parent, Purchaser or any affiliate of Parent or Purchaser shall acquire Common Stock (other than from the Company) at a price in excess of the Purchase Price, then the Purchase Price hereunder shall be increased to such higher price. If the purchase of the Acquired Securities has been completed at the time of such increase, Stockholder shall be entitled to receive, and Purchaser shall promptly (and in no event more than 48 hours following such increase) pay to Stockholder, by wire transfer of same day funds to such account as Stockholder shall designate, the amount of the increase. (d) In the event the Option Securities are acquired by Purchaser pursuant to the exercise of the Securities Option, Stockholder shall be entitled to receive, and Purchaser shall promptly (and in no event more than 48 hours following such Sale) pay to Stockholder, upon any subsequent disposition, transfer or sale to an unaffiliated third party ("SALE") of all or any portion of the Acquired Securities within the one-year period following such acquisition, an amount per share in cash equal to the excess, if any, of the net proceeds received per share in the Sale over the Purchase Price. Any such payment shall be made by wire transfer of same day funds to such account as Stockholder shall designate. 3 4. ADDITIONAL AGREEMENTS. (a) VOTING AGREEMENT. Stockholder shall, at any meeting of the stockholders of the Company, however called, or in connection with any written consent of the stockholders of the Company, vote (or cause to be voted) all Securities then held of record or Beneficially Owned by Stockholder (and, in the case of Securities not held of record by Stockholder, subject to Stockholder's voting direction), (i) in favor of the Merger, the execution and delivery by the Company of the Merger Agreement and the Company Option Agreement and the approval of the terms of each thereof and each of the other actions contemplated by the Merger Agreement, the Company Option Agreement and this Agreement and any actions required in furtherance thereof and hereof; and (ii) against any proposal relating to an Acquisition Transaction and against any action or agreement that would impede, frustrate, prevent or nullify this Agreement, or result in a breach in any respect of any covenant, representation or warranty or any other obligation or agreement of the Company under the Merger Agreement or the Company Option Agreement or which would result in any of the conditions set forth in Exhibit A to the Merger Agreement or set forth in Article VII of the Merger Agreement not being fulfilled.

Stockholder hereby further affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked. Stockholder hereby ratifies and confirms all that such irrevocable proxy may lawfully do or cause to be done by virtue hereof. Such irrevocable proxy is executed and intended to be irrevocable in accordance with the provisions of Section 212 of the DGCL.

Any action taken by the Company or any member of the Board of Directors of the Company, including any action taken by Stockholder in Stockholder's capacity as a Director or officer of the Company, in accordance with Section 6.02 of the Merger Agreement shall be deemed not to violate this Section 4(d).
