The Exchange Ratio shall be adjusted to reflect fully the appropriate effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Parent Common Stock or Company Common Stock), reorganization, recapitalization, reclassification or other like change with respect to Parent Common Stock or Company Common Stock having a record date on or after the date hereof and prior to the Effective Time.

Section 2.2 Exchange of Shares and Certificates .

(a) Exchange Agent . At or prior to the Effective Time, Parent shall engage a nationally-recognized financial institution reasonably satisfactory to the Company to act as exchange agent in connection with the Merger (the " Exchange Agent "). At the Effective Time, Parent shall deposit with the Exchange Agent, in trust for the benefit of the holders of shares of Company Common Stock immediately prior to the Effective Time, for exchange in accordance with this Article II, through the Exchange Agent, certificates representing the shares of Parent Common Stock issuable pursuant to Section 2.1(a). In addition, Parent shall make available by depositing with the Exchange Agent, as necessary from time to time after the Effective Time, cash in an amount sufficient to make the payments in lieu of fractional shares pursuant to Section

6

2.1(e) and any dividends or distributions to which holders of shares of Company Common Stock may be entitled pursuant to Section 2.2(c). All cash and Parent Common Stock deposited with the Exchange Agent shall hereinafter be referred to as the " Exchange Fund ."

(b) Exchange Procedures . Promptly after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the " Certificates "), which at the Effective Time were converted into the right to receive the Merger Consideration pursuant to Section 2.1 hereof, (i) 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 delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration, cash in lieu of any fractional shares pursuant to Section 2.1(e) and any dividends or other distributions payable pursuant to Section 2.2(c). Upon surrender of Certificates for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificates shall be entitled to receive in exchange therefor a certificate or certificates representing that number of whole shares of Parent Common Stock (after taking into account all Certificates surrendered by such holder) to which such holder is entitled pursuant to Section 2.1 (which shall be in uncertificated book entry form unless a physical certificate is requested), payment in lieu of fractional shares which such holder is entitled to receive pursuant to Section 2.1(e) and any dividends or distributions payable pursuant to Section 2.2(c), and the Certificates so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, certificates representing the proper number of shares of Parent Common Stock may be issued to a Person (as defined in Section 8.14(ee)) other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such issuance shall pay any transfer or other taxes required by reason of the issuance of shares of Parent Common Stock to a Person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration (and any amounts to be paid pursuant to Section 2.1(e) or Section 2.2(c)) upon such surrender. No interest shall be paid or shall accrue on any amount payable pursuant to Section 2.1(e) or Section 2.2(c).

(c) Distributions with Respect to Unexchanged Shares . No dividends or other distributions with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.1(e) hereof, until such Certificate has been surrendered in accordance with this Article II. Subject to applicable Law, following surrender of any such Certificate, there shall be paid to the recordholder thereof, without interest, (i) promptly after such surrender, the number of whole shares of Parent Common Stock issuable in exchange therefor pursuant to this Article II, together with any cash payable in lieu of a fractional share of

7

Parent Common Stock to which such holder is entitled pursuant to Section 2.1(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time and a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock, less the amount of any withholding Taxes (as defined in Section 3.10(g)) that may be required thereon.

(d) No Further Ownership Rights in Company Common Stock . All shares of Parent Common Stock and Contingent Stock Rights issued upon the surrender for exchange of Certificates in accordance with the terms of this Article II and any cash paid pursuant to Section 2.1(e) or Section 2.2(c) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Company Common Stock previously represented by such Certificates. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the 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 or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II.

(e) Termination of Exchange Fund . Any portion of the Exchange Fund which remains undistributed to the holders of Certificates six months after the Effective Time shall be delivered to Parent, upon demand, and any holders of Certificates who have not theretofore complied with this Article II shall thereafter look only to Parent for payment of their claim for the Merger Consideration, any cash in lieu of fractional shares of Parent Common Stock pursuant to Section 2.1(e) and any dividends or distributions pursuant to Section 2.2(c).

(f) No Liability . None of Parent, Merger Sub, the Company or the Exchange Agent or any of their respective directors, officers, employees and agents shall be liable to any Person in respect of any shares of Parent Common Stock (or dividends or distributions with respect thereto), Contingent Stock Rights or cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to five years after the Effective Time, or immediately prior to such earlier date on which any shares of Parent Common Stock, any cash in lieu of fractional shares of Parent Common Stock, Contingent Stock Rights or any dividends or distributions with respect to Parent Common Stock issuable in respect of such Certificate would otherwise escheat to or become the property of any Governmental Entity (as defined in Section 3.5), any such shares, Contingent Stock Rights, cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interests of any Person previously entitled thereto.

(g) Investment of Exchange Fund . The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent on a daily basis; provided that no such investment or loss thereon shall affect the amounts payable to former stockholders of the Company after the Effective Time pursuant to this Article II. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable pursuant to this Article II shall promptly be paid to Parent.

8

(h) Withholding Rights . Parent and the Exchange Agent shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement to any Person who was a holder of Company Common Stock immediately prior to the Effective Time such amounts as Parent or the Exchange Agent may be required to deduct and withhold with respect to the making of such payment under the Code or any other provision of federal, state, local or foreign tax law. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person to whom such consideration would otherwise have been paid.

(i) Lost, Stolen or Destroyed Certificates . In the event any Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, such shares of Parent Common Stock and Contingent Stock Rights as may be required pursuant to Section 2.1(a), cash for fractional shares pursuant to Section 2.1(e) and any dividends or distributions payable pursuant to Section 2.2(c); 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 an agreement of indemnification in form reasonably satisfactory to Parent, or a bond in such sum as Parent may reasonably direct as indemnity, against any claim that may be made against Parent or the Exchange Agent in respect of the Certificates alleged to have been lost, stolen or destroyed.

(j) Affiliates . Notwithstanding anything to the contrary herein, to the fullest extent permitted by applicable Law, no certificates representing shares of Parent Common Stock shall be delivered to a Person who may be deemed an "affiliate" of the Company for purposes of Rule 145 under the Securities Act of 1933, as amended (the " Securities Act "), and the applicable rules and regulations of the Securities and Exchange Commission (the " SEC ") thereunder until such Person has executed and delivered to Parent an Affiliate Agreement (as defined in Section 5.15).

Section 2.3 Dissenting Shares . Notwithstanding any provision of this Agreement to the contrary, shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and which are held by holders of such shares of Company Common Stock who properly exercise appraisal rights with respect thereto in accordance with Section 262 of DGCL (the " Dissenting Shares ") shall not be exchangeable for the right to receive the Merger Consideration, and holders of such Dissenting Shares will be entitled only to receive payment of the appraised value of such shares of Company Common Stock in accordance with the provisions of such Section 262 unless and until such holders fail to perfect or effectively withdraw or lose their rights to appraisal and payment under the DGCL. If, after the Effective Time, any such holder fails to perfect or effectively withdraws or loses such right, such shares of Company Common Stock will thereupon be treated as if they had been converted into and to have become exchangeable for, at the Effective Time, the right to receive the Merger Consideration, without any interest thereon. The Company shall give Parent (i) prompt notice of any demands received by the Company for appraisals of shares of Company Common Stock and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal or offer to settle or settle any such demands.
