ARTICLE 2

EFFECT OF THE MERGER ON CAPITAL STOCK; EXCHANGE OF CERTIFICATES

Section 2.1 Conversion of Securities. At and as of the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or its stockholders:

(a) Each share of Common Stock issued and outstanding immediately prior to the Effective Time (except as provided in Section 2.1(b) or Section 2.1(c) below) shall be converted automatically into the right to receive an amount per share equal to $0.34 in cash (the “Merger Consideration”) payable to the holder thereof, without interest, in the manner provided in Section 2.2, less any required withholding Taxes; provided, that it shall be a condition to the receipt by a stockholder of the Company of any Merger Consideration with respect to any share of Common Stock that the certificate representing such share immediately prior to the Effective Time (the “Certificates”) shall have first been delivered to the Paying Agent pursuant to Section 2.2(c), duly endorsed in blank or accompanied by a duly executed stock power. Except as otherwise provided in Section 2.1(b), all shares of Common Stock outstanding immediately prior to the Effective Time shall no longer be outstanding upon the Effective Time and shall automatically be cancelled and shall cease to exist, and each such certificate which immediately prior to the Effective Time represented any shares of Common Stock shall thereafter only represent the right to receive the Merger Consideration therefor.

(b) Notwithstanding anything in this Agreement to the contrary, shares of Common Stock that are outstanding immediately prior to the Effective Time and that are held by

any Person who is entitled to demand and properly demands appraisal of such shares of Common Stock (“Appraisal Shares”) pursuant to, and who complies in all respects with, Section 262 of the DGCL (“Section 262”) shall not be converted into the right to receive the Merger Consideration as provided in Section 2.1(a), but rather the holders of such Appraisal Shares shall be entitled to payment of the fair value of such Appraisal Shares in accordance with Section 262 (and at the Effective Time such Appraisal Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and such holders shall cease to have any right with respect thereto, except the right to receive the fair value of such Appraisal Shares in accordance with Section 262); provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262, then the right of such holder to be paid the fair value of such holder’s Appraisal Shares shall cease and such Appraisal Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive, Merger Consideration as provided in Section 2.1(a). The Company shall give Parent (i) prompt notice of any demands for appraisal received by the Company, withdrawals of such demands, and any other instruments served pursuant to the DGCL and received by the Company and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under DGCL.

(c) Each share of Common Stock held in the treasury of or reserved for issuance by the Company and each share of Common Stock owned by Parent, Merger Sub or any direct or indirect wholly owned subsidiary of Parent or the Company immediately prior to the Effective Time shall be cancelled and extinguished without any conversion thereof and no portion of the Merger Consideration shall be allocated or paid thereto.

(d) Each share of Merger Sub’s common stock, par value $0.01 per share, issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of the Surviving Corporation’s common stock, par value $0.01 per share.

(e) The Merger Consideration shall be adjusted to reflect any change in the number of shares of Common Stock issued and outstanding as of the Effective Time by reason of any stock dividend, stock split, recapitalization, combination, exchange of shares, merger, consolidation, reorganization or the like or any other change in the corporate or capital structure; provided, however, that nothing in this Section 2.1(e) shall be construed as permitting the Company to take any action or enter into any transaction otherwise prohibited by this Agreement.

Section 2.2 Surrender of Shares; Stock Transfer Books.

(a) Prior to the Effective Time, Parent or Merger Sub will designate a bank, trust company or transfer agent to act as paying agent (the “Paying Agent”) to facilitate the receipt by the Company’s stockholders of the Merger Consideration in connection with the Merger.

(b) Promptly after the Effective Time, Parent shall cause the Merger Consideration to be delivered (other than any portion thereof allocable to any Appraisal Shares, which shall be withheld by Parent or the Surviving Corporation to satisfy related appraisal or

dissenters rights matters and the costs thereof) by wire transfer of immediately available funds to an account designated in writing by the Paying Agent (the “Payment Account”). Upon the delivery of the appropriate funds to the Payment Account, Parent and the Surviving Corporation shall have no further liability or obligation with respect to the payment of the Merger Consideration. The Paying Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be paid pursuant to Section 2.1(a) out of the Payment Account. The Payment Account shall be invested by the Paying Agent as directed by Parent; provided, however, that such investments shall be 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, 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 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 Parent or an affiliate of Parent as Parent directs. The Payment Account shall not be used for any purpose other than as set forth in this Section 2.2(b).

(c) Promptly after the Effective Time, the Surviving Corporation shall cause to be mailed to each holder of record of a Certificate whose shares of Common Stock were converted into the right to receive the Merger Consideration pursuant to Section 2.1(a) a letter of transmittal, which shall (i) specify that delivery of the Certificates 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 (ii) provide instructions for the holders of the Certificates to use in effecting the surrender of the Certificates pursuant to such letter of transmittal. 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 contained therein, and along with such other documents as may be required pursuant to such instructions, including those documents set forth in Section 2.1(a), (or, if such shares of Common Stock 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 Common Stock)), the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration which such holder has the right to receive in respect of the shares of 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 Common Stock which 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 is presented to the Paying 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 2.2(c), 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.

required to be deducted or withheld therefrom under the Code or under any provision of state, local or foreign tax Law or under any other applicable Law. To the extent such amounts are so deducted or withheld, 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. As used in this Agreement, “Code” means the Internal Revenue Code of 1986, as amended.

Section 2.3 No Further Ownership Rights in Company Capital Stock. All amounts paid upon the surrender or exchange of shares of Common Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be forwarded to the Paying Agent where they shall be cancelled and exchanged as provided in Section 2.2.

Section 2.4 Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificate, upon the making of an affidavit of that fact by the holder thereof, such amounts as may be required pursuant to Section 2.2 with respect to the number of shares of Common Stock represented by such Certificate; provided, however, that Parent may, in its discretion and as a condition precedent to the payment thereof, require the owner of such lost, stolen or destroyed Certificate to deliver a bond in such sum as Parent may direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Paying Agent with respect to the Certificate alleged to have been lost, stolen or destroyed.

Section 2.5 Termination of Payment Account, Escheat, etc. Any portion of the Payment Account which remains undistributed to the holders of Common Stock for one year after the Effective Time shall be delivered to Parent upon demand, and any holders of certificates formerly representing shares of Common Stock who have not theretofore complied with the exchange procedures set forth above shall thereafter look only to Parent (subject to abandoned property, escheat or similar Laws, as general creditors thereof) for the Merger Consideration, without any interest thereon. None of Parent, the Paying Agent, the Surviving Corporation or any party hereto shall be liable to any Person for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat, or similar Law.

Section 2.6 Company Equity Plans.

(a) As of the Effective Time, each option to purchase Common Stock or stock appreciation right regardless of whether settleable in Common Stock, cash or both (collectively, the “Company Stock Option Awards”) granted under any equity based compensation plan of the Company (the “Company Stock Plans”), that is outstanding under a Company Stock Plan immediately prior to the Effective Time, whether or not then vested or exercisable, shall be, by virtue of the Merger and, except as otherwise provided below, without any action on the part of Parent, Merger Sub or the holders of the Company Stock Option Awards, be cancelled and the holder of such Company Stock Option Awards will, in full settlement of such Company Stock Option Awards, receive from or on behalf of Merger Sub a single lump sum cash payment in an amount (subject to any applicable withholding Tax) equal to the product of (x) the excess, if any,

of the Merger Consideration over the exercise price or base price, as applicable, per share subject to such Company Stock Option Award, multiplied by (y) the total number of shares of Common Stock subject to such Company Stock Option Award (the aggregate amount of such cash payments hereinafter referred to as the “Option Award Consideration”). Merger Sub shall pay or cause to be paid to holders of the Company Stock Option Awards the Option Award Consideration as soon as practicable, and in any event within 30 business days (as such term is defined in Rule 14d-1(g)(3) promulgated under the Exchange Act, “Business Days”), following the Effective Time. In the event that the exercise price or base price, as applicable, of any Company Stock Option Award is equal to or greater than the Merger Consideration, such Company Stock Option Award shall be cancelled without payment therefor and have no further force or effect.

(b) As of the Effective Time, each restricted stock award, whether performance-based, time-based or otherwise (the “Company Restricted Stock Awards”) that is outstanding under any Company Stock Plan immediately prior to the Effective Time, whether or not then vested, shall, by virtue of the Merger and without any action on the part of the holder thereof, be cancelled and converted into the right to receive a single lump sum cash payment in an amount (subject to any applicable withholding Tax) equal to the product of (x) the Merger Consideration multiplied by (y) the total number of shares of Common Stock subject to such Company Restricted Stock Award (the aggregate amount of such cash payments hereinafter referred to as the “Restricted Stock Award Consideration”). Merger Sub shall pay or cause to be paid to holders of the Company Restricted Stock Awards the Restricted Stock Award Consideration as soon as practicable, and in any event within 30 Business Days, following the Effective Time.

(c) Prior to the Effective Time, the Company will adopt such resolutions and will take such other actions as may be reasonably required to effectuate the actions contemplated by this Section 2.6, without paying any consideration or incurring any debts or obligations on behalf of the Company or the Surviving Corporation.

(d) Each of the Paying Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Company Stock Option Awards or Company Restricted Stock Awards such amounts as may be required to be deducted or withheld therefrom under the Code or under any provision of state, local or foreign Tax Law or under any other applicable Law. To the extent such amounts are so deducted or withheld, 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.

reasonably expected to lead to a Superior Proposal and (iv) the Board of Directors (acting through the Special Committee, if such committee still exists, or otherwise by resolution of a majority of its Disinterested Directors) determines in good faith (after consulting with and receiving the advice of outside legal counsel) that taking the actions referred to in clause (x) and (y) below is necessary in order to comply with its fiduciary duties to the stockholders of the Company under applicable Law, then the Company may at any time prior to obtaining Company Stockholder Approval (x) furnish information and data with respect to the Company to the Person making such Acquisition Proposal pursuant to (and only pursuant to) an Acceptable Confidentiality Agreement; provided, that the Company provides Parent with not less than 24 hours prior written notice of its intention to enter into such Acceptable Confidentiality Agreement and the Company advises Parent of any information provided to any Person concurrently with its delivery to such Person and concurrently with such delivery the Company delivers to Parent all such information not previously provided to Parent and (y) enter into, maintain and participate in discussions or negotiations with the Person making such Acquisition Proposal or otherwise cooperate with or assist or participate in, or facilitate, any such discussions or negotiations.

(c) The Board of Directors shall not (A) fail to make the Recommendation to the stockholders of the Company or withdraw (or modify or qualify in any manner adverse to Parent or Merger Sub) the approval, Recommendation or declaration of advisability by the Board of Directors of this Agreement, the Merger or any of the other transactions contemplated hereby, (B) adopt, approve, recommend, endorse or otherwise declare advisable the adoption of any Acquisition Proposal or (C) resolve, agree or publicly propose to take any such actions (each such action set forth in this Section 5.3(c)(i) being referred to herein as an “Adverse Recommendation Change”) or cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other agreement constituting or directly related to, or which is intended to or would be reasonably likely to lead to, any Acquisition Proposal (each, an “Alternative Acquisition Agreement”), other than any Acceptable Confidentiality Agreements, or resolve, agree or publicly propose to take any such actions. Notwithstanding the foregoing, at any time prior to obtaining Company Stockholder Approval, the Board of Directors (acting through the Special Committee, if such committee still exists, or otherwise by resolution of a majority of its Disinterested Directors) may, if the Board of Directors (acting through the Special Committee, if such committee still exists, or otherwise by resolution of a majority of its Disinterested Directors) determines in good faith (after consulting with and receiving the advice of outside legal counsel) that the failure to do so would violate its fiduciary duties to the stockholders of the Company under applicable Law, taking into account all adjustments to the terms of this Agreement that may be offered by Parent pursuant to this Section 5.3(c), (x) make an Adverse Recommendation Change in response to a Superior Proposal received after the date hereof and that does not otherwise result from a breach of Section 5.3(a) or (y) solely in response to either a Superior Proposal received after the date hereof and that did not otherwise result from a breach of Section 5.3(a), cause the Company to

(d) From and after the date hereof, the Company shall promptly advise Parent, orally and in writing, and in any event no later than 24 hours after receipt, in the event the Company or its Representatives receives any Acquisition Proposal together with the material terms and conditions (including the identity of the Persons making such Acquisition Proposal) of such Acquisition Proposal and a copy of any written documentation delivered to the Company or its Representatives in connection therewith.

(e) The Company shall promptly inform its Representatives of the obligations under this Section 5.3. Without limiting the foregoing, it is understood that any violation of the provisions of this Section 5.3 by the Company’s Representatives shall be deemed to be a breach of this Section 5.3 by the Company.

(f) The Company shall not take any action to exempt any Person (other than Parent, Merger Sub and their respective affiliates) from the restrictions on “business

combinations” contained in Section 203 of the DGCL (or any restrictive provision of any other Takeover Law) or otherwise cause such restrictions not to apply (except to the extent that the execution of this Agreement has such an effect or to the extent that the Contribution Agreement or Voting Agreement is deemed to have such an effect with respect to such other Person), or agree to do any of the foregoing, in each case, unless such actions are taken concurrently with a termination of this Agreement pursuant to Section 7.1(d)(ii).

(g) Nothing contained in this Agreement shall prohibit the Company from (i) taking and disclosing a position contemplated by Rules 14e-2(a) or 14d-9 promulgated under the Exchange Act or (ii) making any disclosure to the stockholders of the Company if, in the good faith judgment of the Board of Directors (acting through the Special Committee, if such committee still exists, or otherwise by resolution of a majority of its Disinterested Directors), after consulting with and receiving the advice of outside legal counsel, failure to do so would violate the disclosure requirements under applicable Law; provided, however, that in no event shall this Section 5.3(g) affect the obligations of the Company specified in Section 5.3(a), Section 5.3(b), and Section 5.3(c).

(h) For purposes of this Agreement:

(i) “Acceptable Confidentiality Agreement” means a customary confidentiality agreement containing confidentiality terms no less favorable in any material respect to the Company in the aggregate than those set forth in the Confidentiality Agreement; provided, that such confidentiality agreement shall not prohibit compliance with any of the provisions of this Section 5.3.

(ii) “Acquisition Proposal” means any inquiry (in writing or otherwise), proposal, indication of interest or offer from any Person (other than Parent, Merger Sub or any of their affiliates) or “group” (as defined in Section 13(d) of the Exchange Act) relating to, or that could be reasonably expected to lead to, (A) the direct or indirect acquisition or purchase (whether in a single transaction or a series of related transactions) of assets of the Company equal to 15% or more of the Company’s consolidated assets or to which 15% or more of the Company’s revenues or earnings on a consolidated basis are attributable, (B) the direct or indirect acquisition (whether in a single transaction or a series of related transactions) of 15% or more of any class of equity securities of the Company, (C) a tender offer or exchange offer that if consummated would result in any Person or “group” (as defined in Section 13(d) of the Exchange Act) beneficially owning 15% or more of any class of equity securities of the Company or (D) a merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company, in each case, other than the transactions contemplated by this Agreement.

(iii) “Disinterested Director” means a member of the Board of Directors of the Company who (i) has no direct or indirect interest in Parent, whether as an investor or otherwise, (ii) is not a representative of any Person who has any such interest in Parent and (iii) is not otherwise affiliated with Parent.

(iv) “Superior Proposal” means any bona fide written Acquisition Proposal that the Board of Directors (acting through the Special Committee, if such committee

still exists, or otherwise by resolution of a majority of its Disinterested Directors) determines in good faith (after consulting with and receiving the advice of outside legal counsel and after receiving the advice of the Company Financial Advisor), taking into account all legal, financial, regulatory, estimated time of completion and other aspects of the Acquisition Proposal and the Person making the Acquisition Proposal, including the financing terms thereof, (A) would result in a transaction that is more favorable to the stockholders from a financial point of view than the transactions contemplated by this Agreement (taking into account (1) any adjustment to the terms and conditions proposed by Parent in an offer that is in writing in response to such Acquisition Proposal pursuant to Section 5.3(c) or otherwise and (2) any termination fees and expense reimbursement provisions) and (B) is reasonably likely to be consummated; provided, that for purposes of this definition of “Superior Proposal,” references in the term “Acquisition Proposal” to “15% or more” shall be deemed to be references to “more than 50%.”

Section 5.4 Governmental Filings; Efforts.

(a) Subject to the terms and conditions set forth in this Agreement, each of the Parties shall use its reasonable best efforts promptly to take, or cause to be taken, all actions, and do, or cause to be done, and to assist and cooperate with the other Parties in doing, all things necessary and appropriate to consummate and make effective, and to satisfy all conditions to, in the most expeditious manner practicable, the Merger and the other transactions contemplated by this Agreement, including (i) the obtaining of all necessary actions or nonactions, waivers, consents, clearances, approvals, and expirations or terminations of waiting periods from any Governmental Authorities and the making of all necessary registrations and filings and the taking of all steps as may be necessary and appropriate to effect the foregoing, or to avoid an action or proceeding by, any Governmental Authorities, (ii) the obtaining of all necessary consents, approvals or waivers from third parties to the extent that any such consent or waiver is necessary to permit the Parties to consummate the transactions contemplated by this Agreement and (iii) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by this Agreement.

Neither Parent nor the Company shall commit to or agree (or permit their respective Subsidiaries to commit to or agree) with any Governmental Authority to stay, toll or extend any applicable waiting period under the HSR Act or other applicable Antitrust Laws, without the prior written consent of the other (such consent not to be unreasonably withheld, conditioned or delayed).

For the avoidance of doubt, each Party shall assist the other in gathering, preparing and submitting information or making any filing to any Governmental Antitrust Authority.

(c) Notwithstanding anything to the contrary herein, nothing in this Agreement shall require Parent or any of its Subsidiaries to, nor shall the Company without the prior written consent of Parent agree or proffer to, divest, hold separate, or enter into any license or similar agreement with respect to, or agree to restrict the ownership or operation of, any business or assets of the Company, Parent or any of its Subsidiaries. Notwithstanding anything to the contrary contained herein, in no event shall Parent or any of its Subsidiaries be obligated to litigate or participate in any action, suit, claim, charge, complaint or proceeding, inquiry or investigation brought by any Governmental Authority or appeal any Order of a claim brought by a Governmental Authority (i) challenging or seeking to restrain or prohibit the consummation of the Merger or the other transactions contemplated by this Agreement, or seeking to obtain from Parent or any of its Subsidiaries any damages in relation therewith, (ii) seeking to prohibit or limit in any respect, or place any conditions on, the ownership or operation by the Company, Parent or any of its Subsidiaries of all or any portion of the business or assets or any product of the Company or Parent or its Subsidiaries or to require any such Person to dispose of, license (whether pursuant to an exclusive or nonexclusive license) or hold separate all or any portion of the business or assets or any product of the Company or Parent or its Subsidiaries, in each case as a result of or in connection with the Merger or any of the other transactions contemplated by this Agreement, (iii) seeking to directly or indirectly impose limitations on the ability of Parent or any of its Subsidiaries to acquire or hold, or exercise full rights of ownership of, any shares of Common Stock or any shares of common stock of the Surviving Corporation, including the right

to vote the Common Stock or the shares of common stock of the Surviving Corporation on all matters properly presented to the stockholders of the Company or the Surviving Corporation, respectively or (iv) seeking to (A) directly or indirectly prohibit Parent or any of its affiliates from effectively controlling in any respect any of the business or operations of the Company or (B) directly or indirectly prevent the Company from operating any of their businesses in substantially the same manner as operated by the Company immediately prior to the date of this Agreement.

(d) The Parties acknowledge that the transactions contemplated by this Agreement do not meet the “Size of Transaction” test under the HSR Act and therefore no filing under the HSR Act is required in connection herewith.

Section 5.5 Certain Notices. From and after the date of this Agreement until the Effective Time, each Party hereto shall promptly notify the other Party of (i) the occurrence, or non-occurrence, of any event that would be likely to cause any condition to the obligations of any Party to effect the Merger and the other transactions provided for in this Agreement not to be satisfied or (ii) the failure of the Company, Merger Sub or Parent, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement which would reasonably be expected to result in any condition to the obligations of any Party to effect the Merger and the other transactions provided for in this Agreement not to be satisfied; provided, however, that the delivery of any notice pursuant to this Section 5.5 shall not cure any breach of any representation or warranty requiring disclosure of such matter at or prior to the execution of this Agreement or otherwise limit or affect the remedies available hereunder to the Party receiving such notice.

(c) The agreements and covenants contained herein shall not be deemed to be exclusive of any other rights to which any such present or former director or officer is entitled, whether pursuant to Law, contract or otherwise. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or its officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 5.9 is not prior to or in substitution for any such claims under any such policies.

Section 5.10 Takeover Laws. If any Takeover Law shall become applicable to the Merger or the other transactions contemplated hereby, each of the Company and Parent and the members of their respective boards of directors shall grant such approvals and take such actions as are reasonably necessary so that the transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of such Takeover Law on the Merger and the other transactions contemplated hereby.

the effectiveness of the Credit Agreement Waiver, on terms no less favorable to the Company than those set forth in the Credit Agreement Waiver, until a date not earlier than June 15, 2010. Notwithstanding the foregoing, the aggregate amount of consent, waiver or similar fees payable to the lenders under the Credit Agreement after the date hereof in connection with obtaining the extensions, waivers and/or modifications described in this Section 5.14 shall not exceed $50,000.

Section 5.15 Closing Conditions. Each of the Parties shall use its reasonable best efforts to effectuate the transactions contemplated hereby and to fulfill and to cause to be fulfilled the conditions to closing under this Agreement.

Section 7.3 Fees and Expenses.

(a) In the event that:

(iii) this Agreement is terminated by the Company pursuant to Section 7.1(d)(ii); or

(iv) this Agreement is terminated by Parent pursuant to Section 7.1(c)(ii) or Section 7.1(c)(iii) (or by Parent or the Company pursuant to Section 7.1(b)(i) following any time at which Parent was entitled to terminate this Agreement pursuant to Section 7.1(c)(ii) or Section 7.1(c)(iii))

the Company shall pay to Parent (A) a termination fee (the “Termination Fee”) of (x) $1,000,000 (in any such event under clause (i), (ii) or (iii) of this Section 7.3(a)) or (y) $500,000 (in any such event under clause (iv) of this Section 7.3(a)) and (B) to the extent not previously paid pursuant to the immediately following sentence, all of Parent’s out-of-pocket fees and expenses (including legal and other advisors fees and expenses) actually incurred by Parent and its affiliates on or prior to the termination of this Agreement in connection with the transactions contemplated by this Agreement up to a maximum amount of $600,000 (the “Parent Expenses”). In the event that this Agreement is terminated by the Company or Parent pursuant to Section 7.1(b)(i) and no Termination Fee is payable (or yet payable) in respect thereof pursuant to the immediately preceding sentence, then the Company shall pay to Parent the Parent Expenses. Any payment of the Termination Fee required to be made pursuant to clause (i) of this Section 7.3(a) shall be made to Parent concurrently with the earlier to occur of (x) entry into a definitive agreement with respect to and (y) consummation of the transaction contemplated by the Acquisition Proposal referred to therein; any payment of the Termination Fee required to be made pursuant to clause (ii) or clause (iv) of this Section 7.3(a) shall be made to Parent promptly following termination of this Agreement by Parent as set forth in such clause (ii) or clause (iv), as applicable (and in any event not later than three Business Days after delivery to the Company of notice of demand for payment), and any payment of the Termination Fee required to be made pursuant to clause (iii) of this Section 7.3(a) shall be made to Parent at the time provided for in Section 7.1(d)(ii). If the Company is required to pay Parent Expenses hereunder, the Company shall pay to Parent the Parent Expenses as promptly as possible (but in any event within three Business Days) following receipt by the Company of an invoice therefore. The Termination Fee and the Parent Expenses shall be payable by wire transfer of immediately available funds in accordance with wire transfer instructions provided by Parent; provided, that in the event this

Agreement is terminated by Parent pursuant to Section 7.1(c)(ii), payment of the Termination Fee (but not the Parent Expenses) may be satisfied, at the election of the Company, by issuance to Parent of a number of shares of Common Stock equal to the Termination Fee divided by the Merger Consideration in lieu of a payment of immediately available funds.

(b) All such payments shall be made by wire transfer of immediately available funds to an account to be designated by Parent or, if Parent fails to timely designate an account, by cashier’s check payable to the order of Parent delivered to Parent at the address specified in Section 8.2.

(c) Except as set forth in Section 7.3(a), all fees and expenses incurred in connection with this Agreement and the transactions contemplated by this Agreement shall be paid by the Party incurring such expenses, whether or not the Merger is consummated. Other than any Taxes imposed upon a holder of shares of Common Stock or Company Equity Awards (which shall be paid by or withheld on behalf of such holder), the Company shall pay all Taxes incident to preparing for, entering into, and carrying out this Agreement and the consummation of the transactions contemplated by this Agreement, including (i) transfer, stamp, and documentary Taxes or fees and (ii) sales, use, gains, real property transfer, and other or similar Taxes or fees.

(d) In the event that the Company shall fail to pay the Termination Fee and/or Parent Expenses required pursuant to this Section 7.3 when due, such Termination Fee and/or Parent Expenses, as the case may be, shall accrue interest for the period commencing on the date such Termination Fee and/or Parent Expenses, as the case may be, became past due, at a rate equal to the rate set forth in the New York edition of The Wall Street Journal on such date under the “Treasury” section for “1-Year Note” plus 300 basis points. In addition, if the Company shall fail to pay such Termination Fee and/or Parent Expenses, as the case may be, when due, the Company shall also pay to Parent all of Parent’s costs and expenses (including attorneys’ fees) in connection with efforts to collect such Termination Fee and/or Parent Expenses, as the case may be.

(e) The Company acknowledges that the fees (including the Termination Fee), Parent Expenses reimbursement and the other provisions of this Section 7.3 are an integral part of this Agreement and the transactions contemplated hereby and that, without these agreements, Parent and Merger Sub would not enter into this Agreement. Each of the Parties acknowledges that the Termination Fee is not a penalty, but rather a reasonable amount that will compensate Parent and Merger Sub for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision.

Section 7.4 Extension; Waiver. At any time prior to the Effective Time, the Parties may, to the extent permitted by applicable Law, subject to Section 7.5, (a) extend the time for the performance of any of the obligations or other acts of the other Parties, (b) waive any inaccuracies in the representations and warranties of the other Parties contained herein or in any document delivered pursuant hereto or (c) waive compliance with any of the agreements of the other Parties or conditions to such Party’s obligations contained herein, other than the condition

specified in Section 6.1(a), which no Party may waive; provided, however, that after the Company Stockholder Approval has been obtained, there may not be any extension or waiver of this Agreement which decreases the Merger Consideration or which adversely affects the rights of the Company’s stockholders hereunder without the approval of such stockholders. 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 7.5 Amendment. This Agreement may be amended by the Parties by action taken by or on behalf of their respective boards of directors or similar governing body at any time prior to the Effective Time; provided, however, that, after the Company Stockholder Approval has been obtained, no amendment may be made without further stockholder approval which, by Law or in accordance with the rules of any relevant stock exchange, requires further approval by such stockholders. This Agreement may not be amended except by an instrument in writing signed by the Parties.

Section 8.3 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 Merger is not affected in any manner materially adverse to Parent or the Surviving Corporation. 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 in a mutually acceptable manner so as to effect the original intent of the Parties as closely as possible with respect to the consummation of the Merger.

Section 8.4 Entire Agreement. This Agreement (together with the Annexes, Exhibits, Company Disclosure Letter, the Contribution Agreement, Voting Agreement, and the other documents delivered pursuant hereto) constitute the entire agreement of the Parties and supersede all prior agreements and undertakings, both written and oral, between the Parties, or any of them, with respect to the subject matter hereof and thereof and, except as otherwise expressly provided herein, are not intended to confer upon any other Person any rights or remedies hereunder. EACH PARTY HERETO AGREES THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, NONE OF PARENT, MERGER SUB AND THE COMPANY MAKES ANY OTHER REPRESENTATIONS OR WARRANTIES, AND EACH HEREBY DISCLAIMS ANY OTHER REPRESENTATIONS OR WARRANTIES MADE BY ITSELF OR ANY OF ITS RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, FINANCIAL AND LEGAL ADVISORS OR OTHER REPRESENTATIVES, WITH RESPECT TO THE EXECUTION AND DELIVERY OF THIS AGREEMENT OR THE MERGER, NOTWITHSTANDING THE DELIVERY OR DISCLOSURE TO THE OTHER OR THE

OTHER’S REPRESENTATIVES OF ANY DOCUMENTATION OR OTHER INFORMATION WITH RESPECT TO ANY ONE OR MORE OF THE FOREGOING.

Section 8.5 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 except either Parent or Merger Sub may assign all or any of its rights and obligations hereunder to any direct or indirect wholly owned Subsidiary of Parent. No assignment by any Party shall relieve such Party of any of its obligations hereunder. Subject to the foregoing, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns.

Section 8.6 Mutual Drafting. Each Party has participated in the drafting of this Agreement, which each Party acknowledges is the result of extensive negotiations between the Parties. If an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if it is drafted by all the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of authorship of any of the provisions of this Agreement.

Section 8.7 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and, except as specifically set forth in Section 5.9(b), nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit, or remedy of any nature whatsoever under or by reason of this Agreement.

Section 8.8 Specific Performance. Each Party agrees that irreparable damage may occur in the event any provision of this Agreement was not performed in accordance with the terms hereof and that the Parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or in equity.

Section 8.9 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

Section 8.10 Jurisdiction. Each of the Parties irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by the other party hereto or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the Parties hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts. Each of the Parties hereby irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement,

(a) any claim that it is not personally subject to the jurisdiction of the aforesaid courts for any reason other than the failure to serve in accordance with this Section 8.10, (b) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) to the fullest extent permitted by the applicable Law, any claim that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

Section 8.11 Waiver of Jury Trial. EACH OF THE PARTIES IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 8.12 Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 8.13 Interpretation. When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article or Section of this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant to this Agreement unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein.

Section 8.14 Counterparts. This Agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by the different Parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.
