1.9 Exchange of Certificates.

(a) Payment Agent. On or prior to the Closing Date, Parent shall select a reputable bank or trust company to act as payment agent in the Merger (the “Payment Agent”). At the Effective Time, Parent shall deposit with the Payment Agent cash sufficient to pay the cash consideration payable pursuant to Section 1.5 (excluding the Escrow Amount and the Stockholders’ Agent Escrow Amount). The cash amount so deposited with the Payment Agent is referred to as the “Payment Fund.” The Payment Agent will invest the funds included in the Payment Fund in the manner directed by Parent. Any interest or other income resulting from the investment of such funds shall be the property of, and will be paid to, Parent.

(b) Letter of Transmittal – Capital Stock. Promptly after the Effective Time, but in no event later than five days thereafter, Parent shall cause the Payment Agent to mail to each record holder of Company Capital Stock immediately prior to the Effective Time: (i) a letter of transmittal containing such provisions as Parent or the Payment Agent may, subject to reasonable approval of the Stockholders’ Agent, specify (including a provision confirming that delivery of Company Stock Certificates (as defined in Section 1.9(d)) shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon delivery of such Company Stock Certificates to the Payment Agent, and a provision whereby such holder agrees to be bound by the provisions of Sections 1.9, 9 and 10.1) (a “Letter of Transmittal”); and (ii) instructions for use in effecting the exchange of Company Stock Certificates for the Merger Consideration, if any, payable with respect to such Company Capital Stock. Upon the surrender to the Payment Agent of a Company Stock Certificate (or an affidavit of lost stock certificate as described in Section 1.9(e)), together with a duly executed Letter of Transmittal and such other documents as Parent or the Payment Agent may reasonably request, the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor cash in an amount equal to the Merger Consideration, if any, which such holder has the right to receive pursuant to Section 1.5, and the Company Stock Certificate so surrendered shall forthwith be canceled. From and after the Effective Time, each Company Stock Certificate which prior to the Effective Time represented shares of Company Capital Stock shall be deemed to represent only the right to receive the Merger Consideration, if any, payable with respect to such shares, and the holder of each such Company Stock Certificate shall cease to have any rights with respect to the shares of Company Capital Stock formerly represented thereby. The

letter of transmittal shall include a request for each such stockholder of the Company to deliver to the Payment Agent a duly completed and signed copy of United States Internal Revenue Service Form W-9 or Internal Revenue Service Form W-8BEN (or other appropriate United States Internal Revenue Service Form W-8).

(c) Payments to Others. If payment of Merger Consideration in respect of shares of Company Capital Stock converted pursuant to Section 1.5 is to be made to a Person other than the Person in whose name a surrendered Company Stock Certificate is registered, it shall be a condition to such payment that the Company Stock 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 such payment in a name other than that of the registered holder of the Company Stock Certificate surrendered or shall have established to the satisfaction of Parent that such Tax either has been paid or is not payable.

(d) Stock Transfer Books. As of the Effective Time, the stock transfer books of the Company shall be closed and there shall not be any further registration of transfers of shares of Company Capital Stock thereafter on the records of the Company. If, after the Effective Time, certificates for shares of Company Capital Stock (“Company Stock Certificates”) are presented to the Surviving Corporation, they shall be canceled and exchanged for the Merger Consideration, if any, payable with respect to such shares as provided for in Section 1.5. No interest shall accrue or be paid on any Merger Consideration payable upon the surrender of a Company Stock Certificate which immediately before the Effective Time represented outstanding shares of Company Capital Stock.

(e) Lost Certificates. In the event any Company Stock Certificate representing shares of Company Capital Stock converted in connection with the Merger pursuant to Section 1.5 shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the payment of any Merger Consideration with respect to the shares of Company Capital Stock previously represented by such Company Stock Certificate, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such amount, form and with such surety as Parent may reasonably direct) as indemnity against any claim that may be made against the Payment Agent, Parent, the Surviving Corporation or any affiliated party with respect to such Company Stock Certificate.

(f) Undistributed Payment Funds. Any portion of the Payment Fund that remains undistributed to Effective Time Holders as of the date that is 180 days after the Closing Date shall be delivered to Parent upon demand, and Effective Time Holders who have not theretofore surrendered their Company Stock Certificates in accordance with this Section 1.9 shall thereafter look only to Parent for satisfaction of their claims for the Merger Consideration payable with respect to the shares of Company Capital Stock previously represented by such Company Stock Certificates, without any interest thereon.

(g) Escheat. Notwithstanding anything in this Agreement to the contrary, neither Parent nor any other Person shall be liable to any holder of shares of Company Capital Stock or to any other Person for any amount paid to a public official pursuant to applicable abandoned property law, escheat law or similar Legal Requirement. Any amounts remaining unclaimed by holders of shares of Company Capital Stock three years after the Effective Time (or such earlier date immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Body) shall, to the extent permitted by applicable Legal Requirements, become the property of Parent free and clear of any Encumbrance.

11.

(h) Withholding. Each of the Payment Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement to any security holder or former security holder of the Company such amounts as Parent determines in good faith are required to be deducted or withheld therefrom or in connection therewith under the Code or 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 and subsequently paid to the appropriate taxing authority by Parent, Surviving Corporation or the Payment Agent, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

1.10 Further Action. If, at any time after the Effective Time, any further action is reasonably determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation or Parent with full right, title and possession of and to all rights and property of Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.
