     (b) As soon as practicable after the Effective Time (but in no event more than five business days after the Effective Time), the Surviving Corporation shall cause to be mailed to each record holder, as of the Effective Time, of an outstanding certificate or certificates which immediately prior to the Effective Time represented Shares (the “ Certificates ”), a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Paying Agent, and shall be in such form and have such other provisions not inconsistent with this Agreement as Parent and the Surviving Corporation shall reasonably specify) and instructions for use in effecting the surrender of the Certificates for payment of the Merger Consideration therefor. Upon surrender to the Paying Agent of a Certificate, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each Share formerly represented by such Certificate, and such Certificate shall then be cancelled. Until so surrendered, each Certificate will represent, from and after the Effective Time, only the right to receive the Merger Consideration in cash as contemplated by this Article II. No interest shall be paid or accrued for the benefit of holders of the Certificates on the Merger Consideration payable upon the surrender of the Certificates. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition of payment that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such payment shall have paid any transfer and other taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of the Surviving Corporation that such tax either has been paid or is not applicable. As used in this Agreement, “ Person ” means an individual, corporation, limited liability company, partnership, association, trust, unincorporated organization, other entity or group (as defined in the Exchange Act).

     (c) In the event any Certificates shall have been lost, stolen or destroyed, the Paying Agent shall deliver in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration to which the holder thereof is entitled pursuant to this Article II; provided , however , that Parent or the Surviving Corporation may, as a condition precedent to such delivery, require the owner of such lost, stolen or destroyed Certificates to deliver a bond in such sum as they may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Corporation, the Company or the Paying Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

     (d) At any time following six months after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest and other income received with respect thereto) which had been made available to the Paying Agent and which have not been disbursed to holders of Certificates, and thereafter such holders shall be entitled to look to the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) only as general creditors thereof with respect to the Merger Consideration payable, without interest, to which such holders may be entitled pursuant to this Article II. Notwithstanding the foregoing, none of the Surviving Corporation, the Paying Agent

-5-

or any party hereto shall be liable to any Person in respect of any Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

     (e) At the close of business on the day of the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of shares of Company Common Stock on the records of the Company. From and after the Effective Time, the holders of Certificates evidencing ownership of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided for herein or by applicable Law.

     Section 2.5. Withholding Taxes . Each of the Paying Agent, the Company, Parent and the Surviving Corporation shall be entitled to deduct and withhold from the Merger Consideration or Merger Consideration otherwise payable to a holder of Company Common Stock, Company Stock Options or Restricted Shares, as the case may be, pursuant to the Merger such amounts as the Paying Agent, the Company, Parent or the Surviving Corporation is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “ Code ”), or under any applicable provision of state, local or foreign Law. To the extent that amounts are so withheld, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Company Common Stock, Company Stock Options or Restricted Shares, as the case may be, in respect of which such deduction and withholding was made by the Paying Agent, the Company, Parent or the Surviving Corporation, respectively.

     Section 2.6. 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 Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company and 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.
