SECTION 2.02.  Payment of Merger Consideration.   (a)  Paying Agent.   Prior to the Effective Time, Parent shall select a bank or trust company reasonably acceptable to the Company to act as paying agent (the “ Paying Agent ”) for the payment of the Merger Consideration as provided in Section 2.01(c).  Parent shall take all steps necessary to enable and shall cause the Surviving Corporation to provide to the Paying Agent, on a timely basis, at or immediately after the Effective Time, cash necessary to pay for the shares of Company Common Stock converted into the right to receive the Merger Consideration pursuant to Section 2.01(c) (such cash being hereinafter referred to as the “ Exchange Fund ”).

(b)  Exchange Procedure.   Promptly (and in any event no later than five Business Days) after the Effective Time, the Paying Agent shall mail to each holder of record of a certificate or certificates, or a non-certificated share or non-certificated shares, that immediately prior to the Effective Time represented outstanding shares of Company

4

Common Stock (the “ Certificates ” or “ Book-Entry Shares ”, respectively) which were converted into the right to receive the Merger Consideration pursuant to Section 2.01(c) (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares, as applicable, shall pass, only upon delivery of the Certificates or Book-Entry Shares, as applicable, to the Paying Agent, and shall be in customary form and have such other provisions as any party may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates or Book-Entry Shares, as applicable, in exchange for the Merger Consideration.  Upon (A) in the case of a Certificate, surrender of such Certificate to the Paying Agent for cancellation, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Paying Agent or (B) in the case of Book-Entry Shares, receipt of an “agent’s message” by the Paying Agent (or such other evidence, if any, of the transfer as the Paying Agent may reasonably request), the holder of such Certificate or Book-Entry Share, as applicable, shall be entitled to receive in exchange therefor the Merger Consideration for each share of Company Common Stock theretofore represented by such Certificate or Book-Entry Share, as applicable, pursuant to Section 2.01(c), and the Certificate or Book-Entry Share, as applicable, so surrendered shall forthwith be canceled.  In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, payment may be made to a Person other than the Person in whose name the Certificate or Book-Entry Share, as applicable, so surrendered is registered, if such Certificate or Book-Entry Share, as applicable, shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or Book-Entry Share, as applicable, or establish to the reasonable satisfaction of Parent that such Tax has been paid or is not applicable.  Until surrendered as contemplated by this Section 2.02, each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration in accordance with this Article II.  No interest shall be paid or accrue on the cash payable upon surrender of any Certificate or Book-Entry Share.

(c)  No Further Ownership Rights in Company Common Stock.   The Merger Consideration paid in accordance with the terms of this Article II upon the surrender of any Certificate or Book-Entry Share shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock that such Certificate or Book-Entry Share represented immediately prior to the Effective Time. After the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Company Common Stock that were outstanding immediately prior to the Effective Time.  If, after the Effective Time, any Certificates or Book-Entry Shares are presented to the Surviving Corporation or the Paying Agent for any reason, they shall be canceled and exchanged as provided in this Article II.  No cash payment with respect to the Merger Consideration shall be paid to the holder of any unsurrendered Certificate or Book-Entry Share until the surrender of such Certificate or Book-Entry Share in accordance with this Section 2.02.

(d)  Termination of Exchange Fund.   Any portion of the Exchange Fund that remains undistributed to the holders of Certificates or Book-Entry Shares for one

5

year after the Effective Time shall be delivered to Parent, upon demand, and any former holder of Company Common Stock entitled to payment of Merger Consideration who has not theretofore complied with this Article II shall thereafter look only to Parent for payment of its claim for Merger Consideration.

(e)  No Liability.   None of Parent, Merger Sub, the Surviving Corporation or the Paying Agent shall be liable to any Person in respect of any cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.  If any Certificate or Book-Entry Share has not been surrendered immediately prior to the date on which the Merger Consideration in respect of such Certificate or Book-Entry Share would otherwise escheat to or become the property of any Governmental Entity, any such Merger Consideration in respect of such Certificate or Book-Entry Share shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

(f)  Investment of Exchange Fund.   The Paying Agent shall invest any cash included in the Exchange Fund, as directed by Parent, on a daily basis.  Any interest and other income resulting from such investments shall be paid to Parent.  No such investment or any loss thereon shall affect the amounts payable pursuant to this Article II.   Parent shall take actions necessary to ensure that the Exchange Fund includes at all times cash in an amount sufficient for the Paying Agent to pay the Merger Consideration in accordance with this Agreement.

(g)  Lost Certificates.   If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Paying Agent, or, if the undistributed portion of the Exchange Fund has been returned to Parent pursuant to Section 2.02(d), by Parent, the posting by such Person of a bond in such reasonable and customary amount as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent or Parent, as applicable, shall deliver in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration.

(h)  Withholding Rights.   Each of the Surviving Corporation, Merger Sub, Parent and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as may be required to be deducted and withheld with respect to the making of such payment under any applicable Tax Law.  Amounts so withheld and paid over to the appropriate Taxing Authority shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction or withholding was made.
