Section 3.1.1. Each share of common stock, par value $.01 per share, of the Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time (other than any shares of Company Common Stock to be canceled pursuant to Section 3.1.2, and any shares of Company Common Stock that are held by stockholders exercising appraisal rights pursuant to Section 262 of the DGCL (“Dissenting Stockholders”)) (and for purposes hereof each share of Company Common Stock shall be deemed to include the associated rights of the Company (the “Company Rights”) attributable to such share pursuant to the Rights Agreement, dated as of February 6, 1997, between the Company and American Stock Transfer & Trust Company, as Rights Agent, as amended (the “Company Rights Agreement”)), shall be converted, subject to Section 3.2.4, into the right to receive Twenty Dollars ($20.00) in cash, payable to the holder thereof, without interest (the “Merger Consideration”). All such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each Certificate that immediately prior to the Effective Time represented such shares shall thereafter represent the right to receive the Merger Consideration therefor; provided, however, that shares of the Company held by Dissenting Stockholders (“Dissenting Shares”) will be treated in accordance with Section 3.3, and shares to be canceled pursuant to Section 3.1.2 shall be treated as provided in Section 3.1.2. Certificates previously representing shares of Company Common Stock (other than Dissenting Shares or shares to be canceled pursuant to Section 3.1.2) shall be exchanged for the Merger Consideration, without interest, upon the surrender of such Certificates in accordance with the provisions of Section 3.2.

Section 3.1.2. Each share of Company Common Stock held by Parent, Merger Sub, any Subsidiary of Parent or Merger Sub, in the treasury of the Company or by any Company Subsidiary immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof and no payment shall be made with respect thereto.

Section 3.1.3. Each share of common stock, par value $.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and be exchanged for one newly and validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation. Following the Effective Time, each certificate evidencing

ownership of shares of Merger Sub common stock shall evidence ownership of such shares of the Surviving Corporation.

Section 3.1.4. If between the date of this Agreement and the Effective Time the outstanding shares of Company Common Stock shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, then the Merger Consideration, the Option Payments and the Restricted Stock Payments shall be correspondingly adjusted to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares.

Section 3.2. Exchange of Certificates.

Section 3.2.1. At the Closing, Parent shall deposit, or shall cause to be deposited, with StockTrans, Inc. or another bank or trust company designated by Parent and satisfactory to the Company (the “Exchange Agent”), for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Article III through the Exchange Agent, cash in U.S. dollars in an amount sufficient to pay the aggregate amount of the Merger Consideration (the “Exchange Fund”). The Exchange Agent shall, pursuant to irrevocable instructions, deliver out of the Exchange Fund the Merger Consideration contemplated to be paid pursuant to Section 3.1. The cash included in the Exchange Fund shall be invested by the Exchange Agent as directed by Parent; provided, however, that (i) no such investment or losses thereon shall affect the Merger Consideration payable to the holders of Company Common Stock and, following any losses, Parent shall promptly provide additional funds to the Exchange Agent for the benefit of the holders of the shares of the Company Common Stock in the amount of any such losses, and (ii) such investments shall be (a) in obligations of, or guaranteed by, the United States of America or any agency or instrumentality thereof and backed by the full faith and credit of the United States of America, (b) in commercial paper obligations rated A-1 or P-1 or better by Xxxxx’x Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or (c) in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1 billion (based on the most recent financial statements of such bank that are then publicly available). Any net profit resulting from, or interest or income produced by, such investments shall be payable to the Surviving Corporation or Parent, as Parent directs. The cash in the Exchange Fund shall not be used for any other purpose.

Section 3.2.2. Promptly following the Effective Time (but in no event later than two (2) Business Days following the Effective Time), Parent shall instruct 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”) (i) a letter of transmittal in customary form (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 Exchange Agent and the form of which shall be subject to the consent of the Company prior to the Effective Time, such consent not to be unreasonably withheld) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, properly completed and duly executed, and such other documents as may be required pursuant to such instructions (or, if such shares are held in book-entry or

other uncertificated form, upon the entry through a book-entry transfer agent of the surrender of such shares on a book-entry account statement (it being understood that any references herein to “Certificates” shall be deemed to include references to book-entry account statements relating to the ownership of shares of Company Common Stock)), the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration that such holder has the right to receive in respect of the shares of Company Common Stock formerly represented by such Certificate, and the Certificate so surrendered shall forthwith be canceled. No interest will be paid or accrued on any Merger Consideration payable to holders of Certificates. In the event of a transfer of ownership of shares of Company Common Stock that is not registered in the transfer records of the Company, the Merger Consideration may be issued to a transferee if the Certificate representing such shares of Company Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 3.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration or the right to demand to be paid the “fair value” of the shares represented thereby as contemplated by Section 3.3.

Section 3.2.3. All Merger Consideration paid in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Common Stock (and each Company Right associated therewith) in respect of which such payment is made.

Section 3.2.4. Any portion of the Exchange Fund that remains undistributed to the holders of Company Common Stock one year after the Effective Time shall be delivered to the Surviving Corporation upon demand, and any holders of Company Common Stock who have not theretofore complied with this Article III shall thereafter look only to the Surviving Corporation for the Merger Consideration, without any interest thereon.

Section 3.2.5. None of Parent, the Company or the Surviving Corporation shall be liable to any holder of shares of Company Common Stock for any cash from the Exchange Fund delivered to a public official pursuant to any abandoned property, escheat or similar Law.

Section 3.2.6. 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 Parent, the posting by such Person of a bond, in such reasonable and customary amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such lost, stolen or destroyed Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect thereof, without any interest thereon.

Section 3.2.7. Parent, the Surviving Corporation or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Stock such amounts as Parent, the Surviving Corporation or the Exchange Agent is required to deduct and withhold under the Code, or any provision of state, local or foreign tax Law, with respect to the making of such payment. To the extent that amounts are so withheld by Parent, the Surviving Corporation or the Exchange Agent,

such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Common Stock in respect of whom such deduction and withholding was made by Parent, the Surviving Corporation or the Exchange Agent.

Section 3.3. Dissenters’ Rights. Notwithstanding anything in this Agreement to the contrary, if any Dissenting Stockholder shall demand to be paid the “fair value” of such Dissenting Stockholder’s shares of Company Common Stock, as provided in Section 262 of the DGCL, such shares of Company Common Stock (which shall be deemed to include the Company Rights associated with such shares) shall not be converted into or exchangeable for the right to receive the Merger Consideration (except as provided in this Section 3.3) and shall entitle such Dissenting Stockholder only to payment of the fair value of such shares of Company Common Stock, in accordance with Section 262 of the DGCL, unless and until such Dissenting Stockholder withdraws (in accordance with Section 262(k) of the DGCL) or effectively loses the right to dissent. The Company shall give Parent and Merger Sub prompt notice of any written demands for appraisal, withdrawals of demands for appraisal, and any other instrument served pursuant to Section 262 of the DGCL received by the Company. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to, or settle or offer to settle, any such demand for payment of the fair value of a Dissenting Stockholder’s shares of Company Common Stock prior to the Effective Time. If any Dissenting Stockholder shall have effectively withdrawn (in accordance with Section 262(k) of the DGCL) or lost the right to dissent, then as of the later of the Effective Time or the occurrence of such event, the shares of Company Common Stock held by such Dissenting Stockholder shall be cancelled and converted into and represent the right to receive the Merger Consideration payable in respect thereof pursuant to Section 3.1.

Section 3.4. Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed (after giving effect to the exchange of Certificates described in Section 3.2.2) and thereafter, there shall be no further registration of transfers of shares of Company Common Stock theretofore outstanding on the records of the Company. From and after the Effective Time, the holders of Certificates shall cease to have any rights with respect to such shares of Company Common Stock except as otherwise provided herein or by Law. On or after the Effective Time, any Certificates presented to the Exchange Agent or Parent for any reason shall represent the right to receive the Merger Consideration payable in respect thereof as provided herein.

Section 3.5. Company Equity Awards.

Section 3.5.1.

(a) Prior to the Effective Time, the Board of Directors of the Company (or, if appropriate, any committee thereof) (the “Company Board”) shall adopt appropriate resolutions and take all other actions necessary and appropriate to provide that, concurrent with the Effective Time:

(i) each outstanding, unexpired and unexercised option to purchase Company Common Stock (the “Company Options”) granted pursuant to the equity compensation plans set forth in Schedule 3.5.1(a) of the Company

Disclosure Schedule, whether or not then exercisable, conditioned or vested, and irrespective of the exercise price per share thereof, shall fully vest and be deemed to be exercised in full and cancelled and each holder of a Company Option shall be entitled to receive at the Effective Time, in consideration of the deemed exercise and cancellation of such Company Option, a cash payment (such consideration being the “Option Payments”) in an amount equal to the product of (i) the amount of the per share Merger Consideration, less the applicable exercise price per share of such Company Option, and (ii) the total number of shares of Company Common Stock subject to such Company Option (determined on the basis that such Company Option is fully vested and currently exercisable), without interest and subject to any applicable withholding or other Taxes required by applicable Law to be withheld; and

(ii) each outstanding and unvested restricted stock award granted by the Company (“Company Restricted Stock Awards”) pursuant to the equity compensation plans set forth in Schedule 3.5.1(a) of the Company Disclosure Schedule, whether or not then conditioned, shall be deemed to be fully vested and cancelled and each holder of a Company Restricted Stock Award shall be entitled to receive at the Effective Time, in consideration of the deemed cancellation of such Company Restricted Stock Award, a cash payment (such consideration being the “Restricted Stock Payments”) equal to the product of (x) the total number of shares of Company Common Stock subject to such Company Restricted Stock Award immediately prior to the Effective Time and (y) the amount of the per share Merger Consideration; provided, however, that the Restricted Stock Payments shall be paid without interest and shall be subject to any applicable withholding or other Taxes required by applicable Law to be withheld.

Concurrent with the Effective Time, each Company Option and each Company Restricted Stock Award shall be canceled and terminated and shall only entitle the Person who previously held the same to payment of the Option Payment and/or Restricted Stock Payment, as the case may be, payable to such Person as described in this Section 3.5.1. At the Closing, Parent shall take all steps necessary to ensure that the Surviving Corporation or the Company makes all Option Payments and Restricted Stock Payments to the respective Persons entitled thereto in accordance with this Section 3.5.1. Each Option Payment and each Restricted Stock Payment pursuant to this Section 3.5.1(a) shall be made by check, dated the Closing Date, (i) made payable to the respective Person entitled thereto, and (ii) delivered to such Person by hand, or mailed via overnight courier to such Person, on the Closing Date.

(b) Notwithstanding the foregoing, payments pursuant to Section 3.5.1(a) to Persons listed on Schedule 3.5.1(b) of the Company Disclosure Schedule shall be subject to Section 6 of their respective Executive Agreements relating to certain tax matters.

(c) Concurrently with the execution and delivery of this Agreement, the Company has made available to Parent a schedule stating the name of the holder of each Company Option and each Company Restricted Stock Award, the number of shares of Company Common Stock subject to each such Company Option and Company Restricted

Stock Award, and the exercise price of each such Company Option, in each case as of November 30, 2006. Not less than five (5) Business Days prior to the Closing Date, the Company shall update such schedule as necessary so that it will be accurate as of the Closing Date. Such updated schedule shall also reflect (i) the amount of the Option Payment to be made pursuant to this Section 3.5.1 to each holder of a Company Option, (ii) the amount of the Restricted Stock Payment to be made pursuant to this Section 3.5.1 to each holder of a Company Restricted Stock Award, and (iii) the mailing address of each such holder of a Company Option or Company Restricted Stock Award.

Section 3.5.2. The provisions of this Section 3.5 shall survive the consummation of the Merger and are intended to be for the benefit of, and shall be enforceable by, each holder of any Company Options or Company Restricted Stock Awards, and their respective heirs, beneficiaries and representatives.

not be required to provide access to or furnish any information if to do so would contravene any agreement to which the Company or any Company Subsidiary is a party or violate any Law, or where such access to information may involve the waiver of a disclosure privilege or be otherwise adverse to the interests of the Company or any Company Subsidiary.

Section 6.4. No Solicitation of Transactions.

Section 6.4.1. Subject to the other provisions of this Section 6.4, the Company shall, and shall cause each Company Subsidiary to, immediately cease and cause to be suspended any discussions or negotiations with any parties (other than Parent, Merger Sub and the Parent Representatives) that may be ongoing with respect to a Takeover Proposal.

Parent and Merger Sub agree and acknowledge that, with respect to any agreement between the Company and any Third Party that contains a provision prohibiting such Third Party from making a Takeover Proposal without first obtaining from the Company Board a waiver of such provision or consent to such Takeover Proposal, any such waiver or consent on the part of the Company Board may be given by the Company Board and, if given, shall not be considered a solicitation of a Takeover Proposal in violation of this Section 6.4.

Section 6.4.3. The Company shall promptly (and in any event within forty-eight (48) hours) advise Parent orally and in writing of the Company’s receipt of any Takeover

Proposal or any request for information in connection with a possible Takeover Proposal and the material terms and conditions of such Takeover Proposal or request, but not the identity of the Person making such Takeover Proposal.

Section 6.4.4. Nothing contained in this Agreement shall prohibit the Company or the Company Board from (i) taking and disclosing to the stockholders of the Company a position contemplated by Rule 14e-2 promulgated under the Exchange Act or (ii) making any disclosure to the stockholders of the Company if, in the good faith judgment of the Company Board, such disclosure would be necessary under applicable Law (including Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act).

For a period of six (6) years after the Effective Time, Parent shall, or shall cause the Surviving Corporation to, maintain in effect the Company’s current directors’ and officers’ liability insurance (the “D&O Insurance”) in respect of acts or omissions occurring at or prior to the Effective Time, covering each Person currently covered by the D&O Insurance (a complete and accurate copy of which has been heretofore made available to Parent), on terms with respect to the coverage, deductible and amounts no less favorable than those of the D&O Insurance in effect on the date of this Agreement; provided, however, that (i) in satisfying its obligations under this Section 6.9.2, neither Parent nor the Surviving Corporation shall be obligated to pay annual premiums in excess of 200% of the annual amount currently paid by the Company, it being understood and agreed that Parent or the Surviving Corporation shall nevertheless be obligated to provide the maximum amount of such coverage as may be obtained for such annual 200% amount and (ii) in the event of the application of clause (i), any present or former officer or director, upon reasonable written notice thereof (which notice shall be provided no later than twenty (20) days prior to the Effective Time and shall set forth in reasonable detail for each Person to be covered the policy coverage, premiums, deductibles, limitations and other pertinent information), who desires to obtain additional coverage such that, when combined with the coverage obtained by Parent or the Surviving Corporation in accordance with clause (i), it provides insurance coverage equivalent to the D&O Insurance in effect on the date hereof, may so elect and Parent shall or shall cause the Surviving Corporation to acquire such additional coverage on behalf of such Person; provided, further, that in the event any present or former officer or director makes such an election, such present or former officer or director shall pay the portion of the premium of such D&O Insurance in excess of the amount that Parent or the Surviving Corporation is obligated to pay pursuant to this Section 6.9.2. The insurance purchased pursuant to this Section 6.9.2 shall be prepaid in full at the Effective Time and shall be non-cancelable. At the request of the Company, Parent shall arrange for such insurance prior to the Effective Time to be effective only at and after the Effective Time; provided, that Parent shall pay in full for such insurance coverage no later than the Effective Time. At Parent’s election, the Company may acquire a six (6) year tail policy for Persons currently covered by D&O Insurance that is consistent with the first sentence of this Section 6.9.2. Such policy, if acquired by the Company, shall be prepaid at the Effective Time and shall be non-cancelable. If

the Company acquires such a tail policy, Parent’s obligations pursuant to the first sentence of this Section 6.9.2 shall be deemed completely satisfied. The obligation to maintain insurance provided in this Section 6.9.2 shall continue in full force and effect for a period of not less than six (6) years from and after the Effective Time; provided, that in the event any claim or claims are asserted or made within such six year period, Parent and the Surviving Corporation shall ensure that such insurance remains in full force and effect with respect to such claims until final disposition thereof.

Section 6.9.3. If Parent or the Surviving Corporation or any of its successors or assigns shall (i) consolidate with or merge into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfer all or substantially all of its properties and assets to any Person, then, and in each such case, proper provisions shall be made so that the successors and assigns of Parent or the Surviving Corporation (or acquirer of such assets), as the case may be, shall assume all of the obligations of Parent or the Surviving Corporation, as the case may be, set forth in this Section 6.9.

Section 6.9.4. The rights of each Indemnified Party under this Section 6.9 shall be in addition to any right such Person might have under the Company Certificate and the Company Bylaws, the Certificate of Incorporation or the Bylaws of the Surviving Corporation or any comparable organizational documents of their Subsidiaries, or under any agreement of any Indemnified Party with the Company, the Surviving Corporation or any of their respective Subsidiaries.

Section 6.9.5. The provisions of this Section 6.9 shall survive the consummation of the Merger and are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties and their respective heirs and representatives.

Section 6.10. State Takeover Statutes. Parent, the Company and their respective Boards of Directors shall (i) take all reasonable action necessary to ensure that no state takeover statute or similar statute or regulation is or becomes applicable to this Agreement or the transactions provided for in this Agreement and (ii) if any state takeover statute or similar statute becomes applicable to this Agreement or the transactions contemplated by this Agreement, take all reasonable action necessary to ensure that the transactions provided for in this Agreement may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on this Agreement or the transactions provided for in this Agreement.

Section 6.11. Company Rights Agreement. The Company covenants and agrees that, concurrently with or promptly following the execution and delivery of this Agreement, it will take all necessary action (including, if required, redeeming all of the outstanding Company Rights or amending or terminating the Company Rights Agreement) (i) to render the Company Rights Agreement inapplicable to the Merger, this Agreement or any of the transactions contemplated hereby, and (ii) to ensure that no Person is able to exercise any Company Rights under the Company Rights Agreement or enable or require the Company Rights to be separated from the shares of Company Common Stock to which they are attached or to be triggered or to become exercisable, in each case as a result of the Merger, this Agreement or any of the transactions contemplated hereby.

Section 6.12. Section 16 Matters. Prior to the Effective Time, the Company shall take all such steps as may reasonably be necessary and permitted to cause the transactions contemplated by this Agreement, including any dispositions of shares of Company Common Stock (including derivative securities with respect to such shares of Company Common Stock) by each individual who is or will be subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 6.13. Confidentiality Agreement. The Confidentiality Agreement shall continue in full force and effect in accordance with its terms until the earlier of (i) the Effective Time or (ii) the expiration of the Confidentiality Agreement according to its terms.

Section 6.14. Investigation and Agreement by Parent and Merger Sub; No Other Representations or Warranties.

Section 6.14.1. Each of Parent and Merger Sub acknowledges and agrees that it has made its own inquiry and investigation into, and, based thereon, has formed an independent judgment concerning, the Company and the Company Subsidiaries and their businesses and operations, and Parent and Merger Sub have requested such documents and information from the Company as each such Party considers material in determining whether to enter into this Agreement and to consummate the transactions contemplated in this Agreement. In connection with Parent’s and Merger Sub’s investigation of the Company and the Company Subsidiaries and their businesses and operations, Parent, Merger Sub and the Parent Representatives have received from the Company or the Company Representatives certain projections and other forecasts for the Company and the Company Subsidiaries and certain estimates, plans and budget information. Each of Parent and Merger Sub acknowledges and agrees that there are uncertainties inherent in attempting to make such projections, forecasts, estimates, plans and budgets; that Parent and Merger Sub are familiar with such uncertainties; and that Parent and Merger Sub are taking full responsibility for making their own evaluation of the adequacy and accuracy of all estimates, projections, forecasts, plans and budgets so furnished to them or their representatives.

Section 6.14.2. Each of Parent and Merger Sub agrees that, except for the representations and warranties made by the Company that are expressly set forth in this Agreement, the Company has not made and shall not be deemed to have made to Parent, Merger Sub or any of the Parent Representatives any representation or warranty of any kind. Without limiting the generality of the foregoing, each of Parent and Merger Sub agrees that neither the Company, any holder of the Company’s securities nor any of their respective Affiliates or Company Representatives, makes or has made any representation or warranty to Parent, Merger Sub or any of their Representatives or Affiliates with respect to:

(i) any projections, forecasts, estimates, plans or budgets of future revenues, expenses or expenditures, future results of operations (or any component thereof), future cash flows (or any component thereof) or future financial condition (or any component thereof) of the Company or any of the Company Subsidiaries or the future business, operations or affairs of the Company or any of the Company Subsidiaries heretofore or hereafter delivered to

or made available to Parent, Merger Sub or any Parent Representatives or Affiliates; or

(ii) any other information, statement or documents heretofore or hereafter delivered to or made available to Parent, Merger Sub or any Parent Representatives or Affiliates with respect to the Company or any of its Subsidiaries or the business, operations or affairs of the Company or any of its Subsidiaries, except to the extent and as expressly covered by a representation and warranty made by the Company and contained in this Agreement.

Section 7.2.2. The Company shall have performed or complied in all material respects with all agreements and covenants required by this Agreement to be performed or complied with by it at or prior to the Effective Time.

Section 7.3.2. Parent and Merger Sub shall have performed or complied in all material respects with all agreements and covenants required by this Agreement to be performed or complied with by Parent and/or Merger Sub at or prior to the Effective Time.

Section 7.3.3. The Company shall have received a certificate of an executive officer of Parent to the effect set forth in Sections 7.3.1 and 7.3.2.

ARTICLE VIII
TERMINATION, AMENDMENT AND WAIVER

Section 8.1. Termination. This Agreement may be terminated, and the Merger contemplated hereby may be abandoned, at any time prior to the Effective Time, as set forth below in this Section 8.1, by action taken or authorized by the Board of Directors of the terminating Party or Parties, whether before or after the Stockholder Approval:

(a) By mutual written consent of Parent and the Company;

(b) by either Parent or the Company:

(i) if the Stockholder Approval is not obtained at the Company Stockholders’ Meeting or any adjournment thereof at which this Agreement has been voted upon;

(ii) if the Merger shall not have been consummated by August 31, 2007 (the “Termination Date”); provided, however, that the right to terminate this Agreement under this Section 8.1(b)(ii) shall not be available to any Party whose material breach of any provision of this Agreement has been the cause of, or resulted in, the failure of the Merger to occur on or before the Termination Date; or

(iii) if there shall be any Law that makes consummation of the Merger illegal or otherwise prohibited or any Order of any Governmental Entity having competent jurisdiction enjoining the Company, Parent or Merger Sub from consummating the Merger is entered and such Order has become final and nonappealable and, prior to termination pursuant to this Section 8.1(b)(iii), the terminating Party shall have complied in all material respects with its obligations under Section 6.5; provided, however, that the right to terminate this Agreement pursuant to this Section 8.1(b)(iii) shall not be available to any Party whose breach of any provision of this Agreement results in the imposition of any such Order or the failure of such Order to be resisted, resolved or lifted, as applicable.

(i) if (x) Parent or Merger Sub shall have breached any of the covenants or agreements contained in this Agreement to be complied with by Parent or Merger Sub such that the closing condition set forth in Section 7.3.2 would not be satisfied or (y) there exists a breach of any representation or warranty of Parent or Merger Sub contained in this Agreement such that the closing condition set forth in Section 7.3.1 would not be satisfied, and, in the case of either (x) or (y), such breach is incapable of being cured by the earlier to occur of (i) twenty (20) Business Days after Parent or Merger Sub receives written notice of such breach from the Company or (ii) the Termination Date;

(ii) if, prior to the obtaining of the Stockholder Approval, there has been a Company Adverse Recommendation Change; or

(iii) if, prior to the obtaining of the Stockholder Approval, (x) the Company is concurrently entering into a definitive agreement for a Superior Proposal and (y) not later than the day of such termination, Parent has received any Termination Fee required to be paid under Section 8.4.

(d) by Parent:

(i) if (x) the Company shall have breached any of the covenants or agreements contained in this Agreement to be complied with by the Company such that the closing condition set forth in Section 7.2.2 would not be satisfied or (y) there exists a breach of any representation or warranty of the Company contained in this Agreement such that the closing condition set forth in Section 7.2.1 would not be satisfied, and, in the case of either (x) or (y), such breach is incapable of being cured by the earlier to occur of (i) twenty (20) Business Days after the Company receives written notice of such breach from Parent or (ii) the Termination Date;

(ii) if, prior to the obtaining of the Stockholder Approval, (x) there has been a Company Adverse Recommendation Change, (y) the Company has failed to include the Company Recommendation in the Proxy Statement or (z) the Company Board approves or recommends a Takeover Proposal to the holders of Company Common Stock or approves or recommends that holders of Company Common Stock tender their shares of Company Common Stock in any tender offer or exchange offer that is a Takeover Proposal; or

(iii) if the Company shall have materially breached any of its covenants or agreements contained in Section 6.2.3, Section 6.4.1, or Section 6.4.3 of this Agreement such that the closing condition set forth in Section 7.2.2 would not be satisfied and, with respect to a material breach of Section 6.2.3, such breach is incapable of being cured prior to the expiration of ten (10) calendar days after the Company receives written notice of such breach from Parent; provided, however, that the right to terminate this Agreement pursuant to this Section 8.1(d)(iii) shall not be available to Parent if it or Merger Sub is in material breach of any provision of this Agreement.

Section 8.2. Effect of Termination. Except as otherwise set forth in this Section 8.2, in the event of a termination of this Agreement by either the Company or Parent as provided in Section 8.1, this Agreement shall forthwith become void and there shall be no liability or obligation on the part of Parent, Merger Sub or the Company or their respective officers or directors; provided, however, that (i) the provisions of Sections 8.2, 8.3, 8.4, and 8.5 and Article IX and the Confidentiality Agreement shall remain in full force and effect and survive any termination of this Agreement and (ii) the Termination Fee shall be the exclusive remedy of Parent and Merger Sub under circumstances where the Termination Fee is payable by the Company; provided, further, that no Party shall be relieved or released from any liabilities or damages arising out of its willful and material breach of any provision of this Agreement and, in such event, the non-breaching Party or Parties shall be entitled to seek recovery for any and all damages, losses, claims, liabilities, demands, charges, penalties, costs, expenses and/or diminution in value of such Party or Parties. In no event shall any Party be liable for punitive damages.

Section 8.3. Fees and Expenses. Except as otherwise expressly set forth in this Agreement, all fees and expenses incurred in connection herewith and the transactions contemplated hereby shall be paid by the Party incurring such expenses, whether or not the Merger is consummated, except that each of Parent and the Company shall bear and pay one-half of the costs and expenses incurred in connection with the filing, printing and mailing of the Proxy Statement (including any SEC filing fees).

Section 8.4. Termination Fee.

Section 8.4.1. If this Agreement is terminated pursuant to Section 8.1(c)(ii), Section 8.1(c)(iii)(x), Section 8.1(d)(ii) or Section 8.1(d)(iii) and neither Parent nor Merger Sub is in material breach of this Agreement at the time of such termination, then the Company shall pay, or cause to be paid, to Parent $10,000,000 (the “Termination Fee”), which amount shall be inclusive of all Expenses of Parent and Merger Sub, not later than the day of such termination. The Termination Fee shall be paid by wire transfer of immediately available funds to an account designated in writing to the Company by Parent. For the avoidance of doubt, in no event shall the Company be obligated to pay, or cause to paid, the Termination Fee on more than one occasion.

Section 8.4.2. The Company acknowledges that the agreements contained in this Section 8.4 are an integral part of the transactions contemplated in this Agreement, that the damages resulting from termination of this Agreement under circumstances where a Termination Fee is payable are uncertain and incapable of accurate calculation and that the amounts payable pursuant to Section 8.4.1 are reasonable forecasts of the actual damages that may be incurred and constitute liquidated damages and not a penalty, and that, without these agreements, Parent would not enter into this Agreement; accordingly, if the Company fails to promptly pay the Termination Fee, and, in order to obtain such payments Parent commences a suit that results in a judgment against the Company for the Termination Fee, the Company shall pay to Parent its costs and expenses (including reasonable attorney’s fees) in connection with such suit.

Section 8.5. Specific Performance. The Parties recognize that in the event Parent or Merger Sub should refuse to perform under the provisions of this Agreement, monetary damages alone will not be adequate. The Company shall therefore be entitled, in addition to any other

remedies that may be available, including money damages, to obtain specific performance of the terms of this Agreement. In the event of any action to enforce this Agreement specifically, Parent and Merger Sub hereby waive the defense that there is an adequate remedy at law.

Section 8.6. Extension; Waiver. At any time prior to the Effective Time, the Parties may, to the extent permitted by applicable Law, subject to Section 8.7, (i) extend the time for the performance of any of the obligations or other acts of the other Parties, (ii) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto or (iii) waive compliance with any of the agreements or conditions contained herein; provided, however, that after the Stockholder Approval has been obtained, there may not be any extension or waiver of this Agreement that decreases the Merger Consideration or that adversely affects the rights of the holders of Company Common Stock hereunder without the approval of the holders of Company Common Stock. Any agreement on the part of a Party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. The failure of any Party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

Section 8.7. Amendment. This Agreement may be amended by the Parties but only by action taken by or on behalf of their respective Boards of Directors at any time prior to the Effective Time; provided, however, that, after the Stockholder Approval has been obtained, no amendment may be made without further approval of the holders of Company Common Stock that, by Law or in accordance with the rules of any relevant stock exchange or market or trading system, requires further approval by the holders of Company Common Stock. This Agreement may not be amended except by an instrument in writing signed by the Parties.

Section 9.4. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as

No provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than the Parties hereto and their respective successors and permitted assigns; provided, however, that (i) the provisions of Section 3.5, Section 6.8 and Section 6.9 shall inure to the benefit of, and shall be enforceable by, the Persons described in such Sections; and (ii) the stockholders of the Company shall be third party beneficiaries of Article III of this Agreement and shall have the right to enforce such provisions, including the right to seek and recover any and all damages that the stockholders of the Company may incur or suffer as a result of a breach of such provisions.

Section 9.7. Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the Parties (whether by operation of law or otherwise) without the prior written consent of the other Parties.
