(a)           Any Company Option held by any Person that is unexpired, unexercised and outstanding immediately prior to the Effective Time, shall, on the terms and subject to the conditions set forth in this Agreement, terminate in its entirety at the Effective Time, and   the holder of each such terminated Company Option shall be entitled to receive therefor an amount of cash (rounded down to the nearest whole cent) equal to (i) the product of (A) the number of shares of Company Common Stock as to which such Company Option was vested and exercisable immediately prior to the Effective Time, multiplied by (B) the excess, if any, of the Merger Consideration over the per share exercise price of such Company Option immediately prior to the Effective Time,  less (ii) any applicable withholdings in accordance with Section 2.7(c).

From and after the Effective Time, a holder of Dissenting Shares shall not be entitled to exercise any of the voting rights or other rights of a shareholder of the Surviving Corporation nor of a shareholder of Parent.

(b)           Notwithstanding the provisions of Section 2.6(a) , if any holder of shares of Company Common Stock who demands dissenters’ rights of such shares under California Law shall effectively withdraw or lose (through failure to perfect or otherwise) the right to dissent, then, as of the later of the Effective Time and the occurrence of such event, such holder’s shares shall no longer be Dissenting Shares and shall automatically be converted into and represent only the right to receive the consideration for Company Common Stock, as applicable, set forth in Section 2.1 , without interest thereon, upon surrender of the certificate representing such shares.

(c)           The Company shall give Parent (i) prompt notice of any written demands for dissenters’ rights of any shares of Company Common Stock, withdrawals of such demands and any other instruments served pursuant to California Law and received by the Company which relate to any such demand for dissenters’ rights and (ii) the opportunity to participate in all negotiations and proceedings which take place prior to the Effective Time with respect to demands for dissenters’ rights under California Law.

Following the date of this Agreement and in any event not less than three Business Days prior to the mailing of the Proxy Statement to the shareholders of the Company, Parent or Merger Sub shall designate a bank or trust company reasonably acceptable to the Company to act as Paying Agent in connection with the Merger (the “ Paying Agent ”).

Until used for that purpose, the funds shall be invested by the Paying Agent in direct obligations of the U.S. Treasury; provided that no such investment or loss thereon shall affect the amounts payable to Company shareholders pursuant to this Article II . Any interest and other income resulting from such investment shall become a part of the funds, and any amounts in excess of the amounts payable to Company shareholders pursuant to this Article II shall promptly be paid to Parent.

(b)            Surrender Procedures . Promptly after the Effective Time, the Surviving Corporation shall cause the Paying Agent to mail to each person who was a record holder of Company Common Stock immediately prior to the Effective Time, whose shares were converted pursuant to this Article II into the right to receive Merger Consideration, (i) a form of letter of transmittal for use in effecting the surrender of stock certificates which immediately prior to the Effective Time represented Company Common Stock (each, a “ Certificate ”) in order to receive payment of the Merger Consideration (which shall specify that delivery shall be effected, and risk of loss and title to the Certificate shall pass, only upon actual delivery of the Certificates to the Paying Agent, and shall otherwise be in customary form) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for payment of the Merger Consideration. When the Paying Agent receives a Certificate, together with a properly completed and executed letter of transmittal and any other required documents, the Paying Agent shall pay to the holder

of the shares represented by the Certificate, or as otherwise directed in the letter of transmittal, the Merger Consideration with regard to each share represented by such Certificate, less any required Tax withholdings in accordance with Section 2.7(c) below, and the Certificate shall be cancelled. No interest shall be paid or accrued on the Merger Consideration payable upon the surrender of Certificates. If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer and (ii) the Person requesting such payment shall pay to the Paying Agent any transfer or other Taxes required as a result of such payment to a Person other than the registered holder of such Certificate or establish to the satisfaction of the Paying Agent that such Taxes have been paid or are not payable. After the Effective Time, a Certificate shall represent, for all corporate purposes, only the right to receive the Merger Consideration in respect of the shares represented by such Certificate, without any interest thereon.

(c)            Required Withholding . Each of Parent, the Paying Agent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement such amounts that are required to be deducted or withheld therefrom under the Internal Revenue Code of 1986, as amended (the “ Code ”), or under any provision of state, local or foreign Tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld, the amount of such consideration shall be treated for all purposes under this Agreement as having been paid to the Person to whom such consideration would otherwise have been paid.

(d)            Lost, Stolen or Destroyed Certificates . In the event any Certificates shall have been lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of a customary affidavit of that fact by the holder thereof, such cash constituting the Merger Consideration; provided, however, that Parent may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, the Company or the Paying Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

(e)            Delivery of Funds to Parent . At any time which is more than 180 days after the Effective Time, Parent shall be entitled to require the Paying Agent to deliver to it any funds which had been deposited with the Paying Agent and have not been disbursed in accordance with this Article II (including, without limitation, interest and other income received by the Paying Agent in respect of the funds made available to it), and after the funds have been delivered to Parent, Persons entitled to payment in accordance with this Article II shall be entitled to look solely to Parent (subject to abandoned property, escheat or other similar laws) for payment of the Merger Consideration upon surrender of the Certificates held by them, without any interest thereon. Any Merger Consideration remaining unclaimed as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any government entity shall, to the extent permitted by applicable law, become the property of Parent free and clear of any claims or interest of any Person previously entitled thereto. Neither the Surviving Corporation, Parent nor the Paying Agent will be liable to any Person entitled to payment under this Article II for any consideration which is delivered to a public official pursuant to any abandoned property, escheat or similar law.

(f)             No Further Ownership Rights in Company Common Stock. All Merger Consideration paid upon the surrender for exchange of shares of Company Common Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II .

(g)            Further Action . At and after the Effective Time, the officers and directors of Parent and the Surviving Corporation will be authorized to execute and deliver, in the name and on behalf of the Company and Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of Company and Merger Sub, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger.
