The Merger shall become effective at such date and time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware or at such subsequent date and time as Parent and the Company shall agree and specify in the Certificate of Merger. The date and time at which the Merger becomes effective is referred to in this Agreement as the “Effective Time.”

(b) At the Effective Time, the By-Laws of the Company, as in effect immediately prior to the Effective Time, shall be amended and restated to read in their entirety as set forth in Exhibit B attached hereto and, as so amended and restated, shall be the By-Laws of the Surviving Corporation until thereafter amended as provided by Law, the Certificate of Incorporation of the Surviving Corporation and such By-Laws.

ARTICLE II

CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

SECTION 2.01 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of Merger Sub, the Company or the holders of any of the following securities:

(a) Conversion of Company Common Stock. Each share of Company Common Stock (all issued and outstanding shares of Company Common Stock being hereinafter collectively referred to as the “Shares”) issued and outstanding immediately prior to the Effective Time (except as set forth in Section 2.01(b) and any Dissenting Shares) shall be canceled and shall be converted automatically into the right to receive $33.75 in cash, without interest (the “Merger Consideration”). The Merger Consideration is payable in accordance with Section 2.02(b).

(b) Cancellation of Treasury Stock and Parent-Owned Stock. Each Share held in the treasury of the Company and each Share owned by Merger Sub or Parent immediately prior to the Effective Time shall automatically be canceled without any conversion thereof and no payment or distribution shall be made with respect thereto.

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

SECTION 2.02 Exchange of Certificates. (a) Paying Agent. Prior to the Effective Time, Parent shall (i) appoint a bank or trust company reasonably acceptable to the Company (the “Paying Agent”), and (ii) enter into a paying agent agreement, in form and substance reasonably acceptable to the Company, with such Paying Agent for the payment of the Merger Consideration in accordance with this Article II. At the Effective Time, Parent shall deposit, or cause the Surviving Corporation to deposit, with the Paying Agent, for the benefit of the holders of Shares, cash in an amount sufficient to pay the aggregate Merger Consideration required to be paid pursuant to Section 2.01(a) (such cash being hereinafter referred to as the “Exchange Fund”). The Exchange Fund shall not be used for any other purpose. The Exchange Fund 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 Moody’s 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 which are then publicly available). Any net profit resulting from, or interest or income produced by, such investments shall be payable to the Surviving Corporation.

(b) Exchange Procedures. Promptly after the Effective Time, Parent shall cause to be mailed to each person who was, at the Effective Time, a holder of record of Shares

entitled to receive the Merger Consideration pursuant to Section 2.01(a): (i) a letter of transmittal (which shall be in customary form and shall specify that delivery shall be effected, and risk of loss and title to the Shares shall pass, only upon proper delivery of the Shares to the Paying Agent) and (ii) instructions for use in effecting the surrender of the certificates evidencing such Shares (the “Certificates”) or the non-certificated Shares represented by book-entry (“Book-Entry Shares”) in exchange for the Merger Consideration. Upon (A) surrender of a Certificate to the Paying Agent for cancellation, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, or (B) receipt by the Paying Agent of an “agent’s message” in the case of Book-Entry Shares, and, in each case, such other documents as may be required pursuant to such instructions, the holder of such Shares shall be entitled to receive in exchange therefor the Merger Consideration which such holder has the right to receive pursuant to the provisions of this Article II, and the Certificate or Book-Entry Shares so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, payment of the Merger Consideration may be made to a person other than the person in whose name the Certificate or Book-Entry Shares so surrendered are registered if the Certificate or Book-Entry Shares representing such Shares shall be presented to the Paying Agent, accompanied by all documents required to evidence and effect such transfer or otherwise be in proper form for transfer, and the person requesting such payment shall pay any fiduciary or surety bonds or any transfer or other Taxes required solely by reason of the payment of the Merger Consideration to a person other than the registered holder of such Certificate or Book-Entry Shares or establish to the reasonable satisfaction of Parent that such Tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.02, each Certificate or Book-Entry Share shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration to which the holder of such Certificate or Book-Entry Share is entitled pursuant to this Article II. No interest shall be paid or will accrue on any cash payable to holders of Certificates or Book-Entry Shares pursuant to the provisions of this Article II.

(c) No Further Rights. From and after the Effective Time, holders of Shares shall cease to have any rights as stockholders of the Company, except as provided herein or by Law.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Shares one year after the Effective Time shall be delivered to the Surviving Corporation, upon demand, and any holders of Shares who have not theretofore complied with this Article II shall thereafter look only to Parent or the Surviving Corporation for, and Parent and the Surviving Corporation shall remain liable for, payment of their claim for the Merger Consideration. Any portion of the Exchange Fund remaining unclaimed by holders of Shares as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Authority shall, to the extent permitted by applicable Law, become the property of Parent free and clear of any claims or interest of any person previously entitled thereto.

(e) No Liability. None of the Paying Agent, Parent, Merger Sub or the Surviving Corporation shall be liable to any holder of Shares for any cash (including any

dividends or distributions with respect to such Shares) delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(f) Withholding Rights. Each of the Paying Agent, the Surviving Corporation and Parent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares or Company Stock Options such amounts as it is required to deduct and withhold with respect to such payment under all applicable federal, state or local Tax Laws and pay such withholding amount over to the appropriate taxing authority. To the extent that amounts are so properly withheld by the Paying Agent, the Surviving Corporation or Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares or Company Stock Options in respect of which such deduction and withholding was made by the Paying Agent, the Surviving Corporation or Parent, as the case may be.

(g) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, then upon (i) the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, and (ii) if required by the Surviving Corporation, the posting by such person of an indemnity bond in form and substance and with surety reasonably satisfactory to the Surviving Corporation, the Paying Agent shall pay in respect of such lost, stolen or destroyed Certificate the Merger Consideration to which the holder thereof is entitled pursuant to Section 2.01(a).

SECTION 2.03 Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of Shares that were outstanding immediately prior to the Effective Time on the records of the Company. From and after the Effective Time, the holders of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares, except as otherwise provided in this Agreement or by Law. On or after the Effective Time, any Certificates or Book-Entry Shares presented to the Paying Agent or Parent for any reason shall be canceled against delivery of the Merger Consideration to which the holders thereof are entitled pursuant to Section 2.01(a).

SECTION 2.04 Company Stock Options and Restricted Stock. (a) Between the date of this Agreement and the Effective Time, the Company shall take all necessary action (which action shall be effective as of the Effective Time), to (i) terminate the Psychiatric Solutions, Inc. Equity Incentive Plan, the Psychiatric Solutions, Inc. Outside Directors’ Stock Incentive Plan and the 2010 Long-Term Equity Compensation Plan (collectively, the “Company Stock Plans”), (ii) provide that each outstanding option to purchase shares of Company Common Stock granted under the Company Stock Plans (each, a “Company Stock Option”) that is outstanding and unexercised as of immediately prior to the Effective Time, whether or not vested or exercisable, shall become fully vested and exercisable as of the Effective Time, (iii) cancel, as of the Effective Time, each Company Stock Option that is outstanding and unexercised, as of the Effective Time (in each case, without the creation of additional liability to the Company or any Subsidiaries), subject, if applicable, to the payment pursuant to Section 2.04(b) and (iv) provide that each share of restricted Company Common Stock granted under the Company Stock Plans that is outstanding as of immediately prior to the Effective Time shall become fully vested and transferable and that all restrictions on such

restricted Company Common Stock shall lapse as of the Effective Time and accordingly will be eligible to receive the per share Merger Consideration pursuant to Section 2.01(a).

(b) Each holder of a Company Stock Option that is outstanding and unexercised as of immediately prior to the Effective Time and has an exercise price per Share that is less than the per share Merger Consideration shall (subject to the provisions of this Section 2.04) be paid by the Surviving Corporation promptly after the Effective Time, in exchange for the cancellation of such Company Stock Option, an amount in cash equal to the product of (i) the difference between the per share Merger Consideration and the applicable exercise price of such Company Stock Option, and (ii) the aggregate number of Shares that remain issuable upon exercise of such Company Stock Option. Any such payments shall be subject to all applicable federal, state and local Tax withholding requirements. In the event that the exercise price per share of a Company Stock Option is greater than or equal to the per share Merger Consideration, such Company Stock Option shall be canceled without consideration and have no further force or effect.

(c) Prior to the Effective Time, the Company shall take all steps reasonably necessary to cause the Transactions and any other dispositions of Company Common Stock or other equity securities of the Company (including derivative securities) in connection with this Agreement by each person who is a director or officer of the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act, as amended.

SECTION 2.05 Dissenting Shares. (a) Notwithstanding any provision of this Agreement to the contrary and to the extent available under the DGCL, Shares that are outstanding immediately prior to the Effective Time and that are held by any stockholder who is entitled to demand and properly demands the appraisal for such Shares (the “Dissenting Shares”) pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL (“Section 262”) shall not be converted into, or represent the right to receive, the Merger Consideration. Any such stockholder shall instead be entitled to receive payment of the fair value of such stockholder’s Dissenting Shares in accordance with the provisions of Section 262; provided, however, that all Dissenting Shares held by any stockholder who shall have failed to perfect or who otherwise shall have withdrawn or lost such stockholder’s rights to appraisal of such Shares under Section 262 shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without any interest thereon, upon surrender in the manner provided in Section 2.02 of any Certificate or the Book-Entry Shares that formerly evidenced such Shares.

(b) The Company shall give Parent (i) prompt notice of any demands received by the Company for appraisal of any Shares, withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company and (ii) the opportunity to participate in and 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.

(b) A true and complete list of all the Subsidiaries of the Company, together with the jurisdiction of organization of each such Subsidiary and the percentage of the outstanding capital stock or other equity interests of each such Subsidiary owned by the Company, each other Subsidiary of the Company and any other person, is set forth in Section 3.01(b) of the Company Disclosure Schedule. None of the Company or any of its Subsidiaries directly or indirectly owns any material equity or similar interest in, or any interest convertible into or exchangeable or exercisable for any equity or similar interest in, any corporation, partnership, joint venture or other business association or entity (other than the Subsidiaries of the Company).

SECTION 3.02 Certificate of Incorporation and By-Laws. The Company has made available to Parent a complete and correct copy of the Certificate of Incorporation and the By-Laws (or similar organizational documents), each as amended to date, of the Company and each of its Subsidiaries. Such Certificates of Incorporation and By-Laws or similar organizational documents are in full force and effect. Neither the Company nor any of its Subsidiaries is in violation of any of the provisions of its Certificate of Incorporation or By-Laws or similar organizational documents, except, in the case of any Subsidiary of the Company, for violations that, individually or in the aggregate, would not reasonably be expected to have a Company Material Adverse Effect.

There are no material outstanding contractual obligations of the Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire any shares of capital stock or options, warrants or other rights to acquire shares of capital stock of the Company or of any Subsidiary of the Company, or to provide funds to or make any investment (in the form of a loan, capital contribution or otherwise) in any such Subsidiary or any other person.

None of the information supplied by Parent or Merger Sub for inclusion in the Proxy Statement will, at the date it is filed with the SEC or first mailed to the Company’s stockholders or at the time of the Company Stockholders’ Meeting or at the time of any amendment or supplement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading.

SECTION 4.06 Absence of Litigation. As of the date of this Agreement, there is no Action pending or, to the knowledge of the officers of Parent, threatened in writing, against Parent or any of its affiliates before any Governmental Authority that would or seeks to prevent or materially delay the consummation of any of the Transactions or otherwise prevent or materially delay Parent or Merger Sub from performing their obligations hereunder. Neither Parent nor any of its affiliates is subject to any continuing order of, consent decree, settlement agreement or other similar written agreement with, any Governmental Authority, or any order, judgment, injunction or decree of any Governmental Authority that would or seeks to prevent or materially delay the consummation of any of the Transactions or otherwise prevent or materially delay Parent or Merger Sub from performing their obligations hereunder.

SECTION 4.07 Operations of Merger Sub. Merger Sub is a direct, wholly owned Subsidiary of Parent, was formed solely for the purpose of engaging in the Transactions, has engaged in no other business activities and has conducted its operations only as contemplated by this Agreement.

SECTION 4.08 Financing. Parent has delivered to the Company true and complete copies of an executed commitment letter, including excerpts of those portions of each fee letter and engagement letter associated therewith that contain any conditions to funding or “flex” provisions or other substantive provisions (excluding only those provisions related solely to fees and economic terms agreed to by the parties) regarding the terms and conditions of the financing to be provided thereby (together, the “Commitment Letter”), pursuant to which JPMorgan Chase Bank, N.A. has committed to provide Parent and Merger Sub with financing in an aggregate amount of $4,150.0 million. The Commitment Letter, in the form so delivered, is in full force and effect and is a legal, valid and binding obligation of Parent and, to the knowledge of Parent as of the date of this Agreement, the other parties thereto. No event has occurred which, with or without notice, lapse of time or both, would constitute a default or breach on the part of Parent under the Commitment Letter. Parent has fully paid any and all commitment fees or other fees required by the Commitment Letter to be paid as of the date hereof. Parent shall have at the Closing and at the Effective Time immediately available funds in an amount sufficient to consummate the Transactions upon the terms contemplated by this Agreement and to pay all related fees and expenses associated therewith. The financing contemplated by the Commitment Letter is subject to no contingency or conditions other than those set forth in the copies of the Commitment Letter delivered to the Company. As of the date of this Agreement, Parent has no reason to believe that any of the conditions to the financing contemplated by the Commitment Letter will not be satisfied or that such financing will not be available to Merger Sub on the date of the Closing. For the avoidance of doubt, it shall not be a condition to Closing for Parent to obtain any financing.

SECTION 4.09 Brokers. The Company will not be responsible for any brokerage, finder’s or other fee or commission to any broker, finder or investment banker in connection with the Transactions based upon arrangements made by or on behalf of Parent or Merger Sub.

If, at any time prior to the Company Stockholders’ Meeting, any information relating to the Company, Parent or any of their respective affiliates, officers or directors should be discovered by the Company or Parent which should be set forth in an amendment or supplement to the Proxy Statement, so that the Proxy Statement shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading, the party which discovers such information shall promptly notify the other parties, and an appropriate amendment or supplement describing such information shall be filed with the SEC and, to the extent required by applicable Law, disseminated to the stockholders of the Company.

(b) The Company shall establish a record date for, duly call, give notice of, convene and hold a meeting of its stockholders (the “Company Stockholders’ Meeting”), for the purpose of obtaining the Stockholder Approval, and, if there is present at such Company Stockholders’ Meeting, in person or by proxy, sufficient favorable voting power to secure the vote of the stockholders of the Company necessary to satisfy the condition set forth in Section 7.01(a), shall not postpone or adjourn such meeting except to the extent required by Law.

SECTION 6.02 Access to Information; Confidentiality. (a) Except as otherwise prohibited by applicable Law or the terms of any contract entered into prior to the date hereof or as would be reasonably expected to violate any attorney-client privilege, from the date of this Agreement until the Effective Time, the Company shall (and shall cause its Subsidiaries to), at Parent’s expense: (i) provide to Parent and to the officers, directors, employees, accountants, consultants, legal counsel, financing sources, agents and other representatives (collectively, with respect to any person, its “Representatives”) of Parent reasonable access, during normal business hours and upon reasonable prior notice to the Company by Parent, to the officers, employees, agents, properties, offices and other facilities of the Company and its Subsidiaries and to the books and records thereof, and (ii) furnish as promptly as practicable to Parent such information concerning the business, properties, Contracts, assets, liabilities, personnel and other aspects of the Company and its Subsidiaries as Parent or its Representatives may reasonably request.

The Company shall provide to Parent, in accordance with the terms of the Confidentiality Agreement and on a prompt basis, any material non-public information concerning the Company or its Subsidiaries provided to such person which was not previously provided to Parent. The Company shall as promptly as practicable (and in any event within two business days) notify Parent, in the event that the Company or any of its Subsidiaries or Representatives receives any Acquisition Proposal, of the material terms and conditions of any such Acquisition Proposal and the identity of the person making such Acquisition Proposal, and the Company shall keep Parent reasonably informed of any material developments with respect to any such Acquisition Proposal (including any material changes thereto). Except as set forth in this Section 6.03, neither the Company nor any Subsidiary of the Company shall enter into any Acquisition Agreement.

(b) Except as set forth in this Section 6.03, the Company Board (or any committee thereof) shall not, and shall not publicly propose to: (i) withhold, withdraw or modify, in a manner adverse to Parent or Merger Sub, the Company Board Recommendation; (ii) approve or recommend any Acquisition Proposal; or (iii) approve or recommend, or cause or permit the Company or any of its Subsidiaries to enter into, any letter of intent, merger agreement, acquisition agreement or similar agreement with respect to any Acquisition Proposal, other than a confidentiality agreement in accordance with Section 6.03(a) (any such letter or agreement, an “Acquisition Agreement” and the actions described above in each of clauses (i), (ii) and (iii), collectively, the “Specified Board Actions”). Notwithstanding the foregoing, prior to the adoption of this Agreement by the Company’s stockholders at the Company Stockholders’ Meeting, (x) in response to the receipt of a written Acquisition Proposal that is not a result of a breach of Section 6.03(a), if the Company Board (acting through the Special Committee or otherwise) (A) determines in good faith (after consultation with its advisors) that such

Acquisition Proposal is a Superior Proposal and (B) determines in good faith (after consultation with its outside legal counsel) that its failure to take such actions would be inconsistent with its fiduciary duties under applicable Law, then the Company Board (acting through the Special Committee or otherwise) may approve and recommend such Superior Proposal (or any Acquisition Agreement with respect to such Superior Proposal) and, in connection with the approval or recommendation of such Superior Proposal, withdraw or modify the Company Board Recommendation and/or cause the Company to terminate this Agreement (in each case subject to compliance with Section 8.03) or (y) other than in connection with an Acquisition Proposal, if the Company Board (acting through the Special Committee or otherwise) determines in good faith (after consultation with its outside legal counsel) that its failure to take such actions would be inconsistent with its fiduciary duties under applicable Law, then the Company Board (acting through the Special Committee or otherwise) may withdraw or modify the Company Board Recommendation (any action by or on behalf of the Company Board permitted by the foregoing clause (x) or (y), a “Specified Acquisition Action”); provided, however, that no Specified Acquisition Action may be taken until after the fifth business day (or such subsequent business days as provided for by clause (2) of this sentence) (the period inclusive of all such days, the “Notice Period”) following Parent’s receipt of written notice from the Company advising Parent that the Company Board intends to take such Specified Acquisition Action (a “Notice of Adverse Action”) and specifying the reasons therefor, including, if the basis of the proposed action by the Company Board is a Superior Proposal, the material terms and conditions of any such Superior Proposal (it being understood and agreed that (1) during the Notice Period the Company shall, and shall cause its financial advisors and outside legal counsel to, negotiate with Parent in good faith (to the extent Parent desires to negotiate) and (2) any amendment to the terms of such Superior Proposal shall require a new Notice of Adverse Action and a two-business day extension of the Notice Period then applicable). In determining whether to take a Specified Acquisition Action, the Company Board shall take into account any changes to the terms of this Agreement proposed by Parent to the Company in response to a Notice of Adverse Action or otherwise.

(c) Nothing contained in this Agreement shall prohibit the Company from taking and disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or from making any disclosure to the Company’s stockholders if the Company Board (or any committee thereof) determines in good faith (after consultation with its outside legal counsel) that it is required to do so under applicable Law; provided, however, that neither the Company nor the Company Board (nor any committee thereof) shall (i) recommend that the stockholders of the Company tender their Shares in connection with any such tender or exchange offer (or otherwise approve or recommend any Acquisition Proposal) or (ii) withdraw or modify the Company Board Recommendation, unless in the case of each of clause (c)(i) and (c)(ii) hereof, the requirements of Section 6.03(b) shall have been satisfied.

(d) Except as set forth in Section 8.03(d) with respect to an Acquisition Proposal, for purposes of this Agreement:

(i) “Acquisition Proposal” means any bona fide proposal or offer (including any proposal from or to the Company’s stockholders) from any person other than Parent or Merger Sub relating to (A) any direct or indirect acquisition of (1) more

than 15% of the assets of the Company and its consolidated Subsidiaries, taken as a whole, or (2) more than 15% of any class of equity securities of the Company; (B) any tender offer or exchange offer, as defined pursuant to the Exchange Act, that if consummated would result in any person beneficially owning, directly or indirectly, 15% or more of any class of equity securities of the Company; or (C) any merger, consolidation, business combination, recapitalization, liquidation, dissolution or other similar transaction involving the Company.

(ii) “Superior Proposal” means any bona fide written Acquisition Proposal that (A) relates to more than 50% of the outstanding Shares or more than 50% of the assets of the Company and its Subsidiaries, taken as a whole, (B) is on terms that the Company Board determines in good faith (after receiving the advice of its financial advisor and outside counsel and after taking into account all financial, legal, regulatory and other aspects of such proposal and of this Agreement (including the relative risks of non-consummation and any changes to the terms of this Agreement proposed by Parent to the Company, prior to the expiration of the Notice Period, in response to such proposal or otherwise)) are more favorable to the Company’s stockholders than this Agreement and (C) the Company Board determines is reasonably capable of being consummated.

(e) The Company shall (i) promptly request each person that has executed a confidentiality agreement with the Company prior to the date of this Agreement in connection with a process relating to an Acquisition Proposal to return or destroy all confidential information heretofore furnished to such person or its Representatives by or on behalf of the Company or any of its Subsidiaries, (ii) not amend or waive, and shall enforce, the provisions of each such confidentiality agreement, except that, without limiting any other provision of this Agreement, this clause (ii) shall not apply to any standstill provision contained therein to the extent compliance herewith would be inconsistent with the fiduciary duties of the Company Board under applicable Law and (iii) prohibit any access to any third party to any such physical or electronic data room, except as permitted herein.

SECTION 6.04 Directors’ and Officers’ Indemnification and Insurance. (a) The Surviving Corporation and its Subsidiaries shall, and Parent shall cause the Surviving Corporation to, honor and fulfill in all respects the obligations of the Company and its Subsidiaries under any and all indemnification agreements between the Company or any of its Subsidiaries and any of their respective present or former directors and officers (collectively, the “Indemnified Parties”). In addition, the Certificate of Incorporation and By-Laws of the Surviving Corporation shall contain provisions no less favorable with respect to exculpation and indemnification than are set forth in Articles VII and VIII of the Amended and Restated Certificate of Incorporation of the Company, as amended, and Article VII of the By-Laws of the Company, respectively, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Effective Time, were directors, officers, employees, fiduciaries or agents of the Company or any of its Subsidiaries.

(b) For a period of six years after the Effective Time, Parent and the Surviving Corporation shall, jointly and severally, to the fullest extent permitted under applicable Law, indemnify and hold harmless, each Indemnified Party against all costs and expenses (including

In the event of any such claim, action, suit, proceeding or investigation, (i) Parent or the Surviving Corporation shall pay the reasonable fees and expenses of counsel selected by the Indemnified Parties, which counsel shall be reasonably satisfactory to the Surviving Corporation, promptly after statements therefor are received, (ii) neither Parent nor the Surviving Corporation shall settle, compromise or consent to the entry of any judgment in any pending or threatened Action to which an Indemnified Party is a party (and in respect of which indemnification could be sought by such Indemnified Party hereunder), unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such Action or such Indemnified Party otherwise consents, and (iii) the Surviving Corporation shall cooperate in the defense of any such matter; provided, however, that neither Parent nor the Surviving Corporation shall be liable for any settlement effected without the Surviving Corporation’s written consent (which consent shall not be unreasonably withheld or delayed); and provided, further, that, in the event that any claim for indemnification is asserted or made within such six-year period, all rights to indemnification in respect of such claim shall continue until the disposition of such claim. The rights of each Indemnified Person under this Section 6.04(b) shall be in addition to any rights such person may have under the Certificate of Incorporation or the By-Laws or similar organizational documents of the Company and the Surviving Corporation or any of their Subsidiaries, or under any Law or under any agreement of any Indemnified Person with the Company or any of its Subsidiaries.

(c) The Surviving Corporation shall either (i) cause to be obtained at the Effective Time “tail” insurance policies with a claims period of at least six years from the Effective Time with respect to directors’ and officers’ liability insurance in amount and scope at least as favorable as the Company’s existing policies for claims arising from facts or events that occurred on or prior to the Effective Time; or (ii) maintain in effect for six years from the Effective Time, if available, the current directors’ and officers’ liability insurance policies maintained by the Company (provided that the Surviving Corporation may substitute therefor policies of at least the same coverage containing terms and conditions that are not less favorable) with respect to matters occurring prior to the Effective Time; provided, however, that in no event shall the Surviving Corporation be required to expend pursuant to this Section 6.04(c) more than an amount per year equal to 300% of current annual premiums paid by the Company for such insurance; provided, however, that in the event of an expiration, termination or cancellation of such current policies, Parent or the Surviving Corporation shall be required to obtain as much coverage as is possible under substantially similar policies for such maximum annual amount in aggregate annual premiums.

(d) In the event Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall succeed to the obligations set forth in this Section 6.04.

(e) Parent shall cause the Surviving Corporation to perform all of the obligations of the Surviving Corporation under this Section 6.04.

From and after the Effective Time, Parent shall cause the Surviving Corporation and its Subsidiaries to honor in accordance with their terms, all contracts, agreements, arrangements, policies, plans and commitments of the Company and its Subsidiaries as in effect immediately prior to the Effective Time that are applicable to any current or former employees or directors of the Company or any of its Subsidiaries, including all severance agreements listed on Section 3.11(a) of the Company Disclosure Schedule and excluding any of the foregoing to the extent related to equity-based compensation. Parent hereby agrees that, for a period of eighteen months immediately following the Effective Time, it shall, or it shall cause the Surviving Corporation and its Subsidiaries to, provide each Employee with equity-based compensation that is no less favorable than the equity-based compensation then provided to other similarly situated employees of Parent and its Subsidiaries.

(b) Employees shall receive credit for all purposes (including, for purposes of eligibility to participate, vesting, benefit accrual and eligibility to receive benefits, but excluding benefit accruals under any defined benefit pension plan) under any employee benefit plan, program or arrangement established or maintained by Parent, the Surviving Corporation or any of their respective Subsidiaries under which each Employee may be eligible to participate on or after the Effective Time to the same extent recognized by the Company or any of its Subsidiaries under comparable Plans immediately prior to the Effective Time; provided, however, credit need not be recognized to the extent that such recognition would result in any duplication of benefits. Such plan, program or arrangement shall credit each such Employee for service accrued or deemed accrued on or prior to the Effective Time with the Company, any Subsidiary of the Company and all affiliates where service with the affiliate was credited under a comparable Plan of the Company prior to the Effective Time; provided, however, service need not be recognized to the extent that such recognition would result in any duplication of benefits.

(c) With respect to the welfare benefit plans, programs and arrangements maintained, sponsored or contributed to by Parent or its Subsidiaries (other than the Surviving Corporation and its Subsidiaries) after the Effective Time (collectively, “Purchaser Welfare Benefit Plans”) and in which an Employee may be eligible to participate on or after the Effective Time, Parent shall (i) waive, or cause its insurance carrier to waive, all limitations as to preexisting and at-work conditions, if any, with respect to participation and coverage requirements applicable to each participating Employee under any Purchaser Welfare Benefit Plan (other than any dependent life insurance plan) to the same extent waived under a comparable Plan, and (ii) provide credit to each Employee for any co-payments, deductibles and

out-of-pocket expenses paid by such Employee under the Plans during the relevant plan year up to and including the Effective Time.

(d) As of the Closing, Parent shall, or shall cause its affiliates (including the Surviving Corporation) to, satisfy all obligations of the Company and all of its Subsidiaries in respect of any accrued but unpaid vacation, holiday, sick leave, paid time off or similar liability as of the Closing.

(e) Nothing contained herein shall be construed as requiring Parent to continue the employment of any specific person. Furthermore, no provision of this Agreement shall be construed as prohibiting or limiting the ability of Parent to amend, modify or terminate any plans, programs, policies, arrangements, agreements or understandings of Parent or the Company or any of their respective Subsidiaries in accordance with their terms. Nothing in this Section 6.05 shall confer any rights or remedies of any kind upon any Employee or any other person other than the parties hereto and their respective successors and assigns.

SECTION 6.06 Financing. (a) The Company agrees to provide, and shall cause its Subsidiaries and its and their Representatives to provide, all reasonable cooperation in connection with the arrangement of any financing necessary to consummate the Transactions (the “Financing”) as may be reasonably requested by Parent and that is necessary or customary in connection with Parent’s efforts to obtain the Financing (provided that such requested cooperation does not unreasonably interfere with the ongoing operations of the Company and its Subsidiaries), including (i) participation in meetings, road shows, drafting sessions, rating agency presentations and due diligence sessions, (ii) furnishing Parent and its Representatives with real estate and other pertinent information regarding the Company and its Subsidiaries as is necessary or customary in connection with the Financing and any security required therefor, including (A) the financial statements and financial data described in Schedule 6.06(a) and (B) the historical financial statements, information reasonably necessary for the preparation of pro forma financial statements, business and other financial data of the Company and of the type required by Regulation S-X (other than Rule 3-10 thereof) and Regulation S-K under the Securities Act and, in all cases, of the type and form customarily included in offering documents for securities offerings by the Company under Rule 144A under the Securities Act (all information required to be delivered pursuant to this clause (ii) being referred to as the “Required Information”), (iii) executing and delivering any pledge and security documents, currency or interest rate hedging arrangements or other definitive financing documents or other certificates (including a certificate of the chief accounting officer of the Company with respect to solvency matters relating to the Company) and documents as may be reasonably requested by Parent, (iv) using reasonable best efforts to obtain accountants’ comfort letters, accountants’ consent letters, legal opinions, appraisals, lien searches, surveys and title insurance as reasonably requested by Parent and (v) assisting Parent and its financing sources in the preparation of (A) customary offering documents, bank information memoranda (including the execution of

Parent shall, promptly upon termination of this Agreement, reimburse the Company for all reasonable out-of-pocket costs incurred by the Company or its Subsidiaries in connection with such cooperation or any actions contemplated by this Section 6.06(a).

(b) All information regarding the Company obtained by Parent or Merger Sub or its or their Representatives pursuant to Section 6.06(a) shall be kept confidential as and to the extent required by the Confidentiality Agreement; provided that the Company and Parent shall agree to amend or waive the Confidentiality Agreement to the extent such information is required under the federal securities Laws to be included in an offering document in connection with the Financing.

(c) The Company shall commence as soon as reasonably practicable after the receipt of a written request from Parent to do so, offers to purchase and related consent solicitations with respect to any or all of the outstanding debt securities of the Company specified by Parent and permitted by applicable Law (collectively, the “Notes”) on the terms and subject to conditions reasonably requested by Parent (collectively, the “Debt Offers”). Parent shall prepare all necessary documentation in connection with the Debt Offer, subject to review by the Company. Notwithstanding the foregoing, the closing of the Debt Offers shall be conditioned on the consummation of the Merger. Parent shall, promptly upon termination of this Agreement, reimburse the Company for all reasonable out-of-pocket costs incurred by the Company and its Subsidiaries in connection with the actions contemplated by this Section 6.06(c).

SECTION 6.07 Further Action. (a) Each party shall use reasonable best efforts to (i) promptly obtain all authorizations, consents, orders and approvals of all Governmental Authorities and officials that may be or become necessary for its execution and delivery of, and the performance of its obligations pursuant to, this Agreement, (ii) cooperate fully with the other parties in promptly seeking to obtain all such authorizations, consents, orders, approvals, licenses, permits and waivers, (iii) provide such other information to any Governmental Authority as such Governmental Authority may reasonably request in connection herewith, (iv) obtain all necessary consents, approvals or waivers from third parties and (v) execute and deliver any additional instruments necessary to consummate the Transactions and to fully carry out the purposes of this Agreement. Each party hereto agrees to make as promptly as practicable after the date of this Agreement its respective filing, if necessary, pursuant to the HSR Act with respect to the Transactions and to supply as promptly as practicable to the appropriate Governmental Authorities any additional information and documentary material that may be requested pursuant to the HSR Act. Each party hereto agrees to make as promptly as practicable after the date of this Agreement its respective filings and notifications, if any, under any other applicable antitrust, competition, or trade regulation Law, and to supply as promptly as practicable to the appropriate Governmental Authorities any additional information and documentary material that may be requested pursuant to the applicable antitrust, competition, or trade regulation Law.

(b) Without limiting the generality of the undertaking of Parent pursuant to Section 6.07(a), Parent agrees to take any and all steps necessary to avoid or eliminate each and every impediment under any antitrust, competition or trade regulation Law that may be asserted by any Governmental Authority or any other party so as to enable the parties hereto to consummate the Transactions, and in any event prior to the Termination Date, including proposing, negotiating, committing to and effecting, by consent decree, hold separate orders, or otherwise, the sale, divestiture or disposition of such of its assets, properties or businesses or of the assets, properties or businesses to be acquired by it pursuant hereto; provided, however, that any such sale, divestiture, disposition or other arrangement shall be conditioned upon the consummation of the Transactions. In addition, Parent shall defend through litigation on the merits any claim asserted in court by any party in order to avoid entry of, or to have vacated or terminated, any decree, order or judgment (whether preliminary or permanent) that would prevent the Closing prior to the Termination Date. Notwithstanding anything in this Agreement to the contrary, no provision of this Agreement shall require, or be construed to require, Parent or any of its Subsidiaries to agree to or take any action that, individually or in the aggregate, would result in a Burdensome Condition. For purposes of this Agreement, a “Burdensome Condition” shall mean making proposals, executing or carrying out agreements (including consent decrees) or submitting to Laws (i) providing for the license, sale or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets of Parent, the Company or any of their respective Subsidiaries or the holding separate of the capital stock of the Company or any such Subsidiary or (ii) imposing or seeking to impose any limitation on the ability of Parent, the Company or any of their respective Subsidiaries to conduct their respective businesses (including with respect to market practices and structure) or to own such assets or to acquire, hold or exercise full rights of ownership of the business of the Company or its Subsidiaries or of Parent or its Subsidiaries, that, in the case of clause (i) and (ii), would, individually or in the aggregate, reasonably be expected to result in a Behavioral Health Business Material Adverse Effect.

(c) Each party shall promptly notify the other party hereto of any material communication it or any of its affiliates receives from any Governmental Authority relating to the matters that are the subject of this Agreement. Each party shall be entitled to review in advance any proposed substantive communication by any other party to any Governmental Authority in connection with the Transactions, and each party shall make any revisions thereto reasonably requested by the other party. None of the parties to this Agreement shall agree to participate in any meeting with any Governmental Authority in respect of any filings, investigation (including any settlement of the investigation), litigation or other inquiry relating to the matters that are the subject of this Agreement unless it consults with the other party in advance and, to the extent not prohibited by such Governmental Authority, gives the other party the opportunity to attend and participate at such meeting. The parties to this Agreement will coordinate and cooperate fully with each other in exchanging such information and providing such assistance as the other party may reasonably request in connection with the foregoing. The parties to this Agreement will provide each other with copies of all material correspondence, filings or communications between them or any of their Representatives, on the one hand, and any Governmental Authority or members of its staff, on the other hand, with respect to this Agreement and the transactions contemplated by this Agreement; provided, however, that materials may be redacted (i) to remove references concerning the valuation of the Company, (ii) as necessary to comply with contractual arrangements, and (iii) as necessary to address reasonable attorney-client or other privilege concerns. In furtherance of the foregoing, all information exchanged between or among the parties under this Section 6.07 shall be subject to appropriate confidentiality arrangements. Notwithstanding anything to the contrary, the parties agree that, except as otherwise provided by Law, any and all proceedings, hearings and other dealings with Governmental Authorities relating to antitrust matters shall be led by Parent and its Representatives; provided, that Parent may make all final strategic decisions after consulting in good faith with the Company.

(d) Neither Parent nor Merger Sub shall enter into any agreement, transaction, or any agreement to effect any transaction (including any merger or acquisition) that might reasonably be expected to make it materially more difficult, or to materially increase the time required, to: (i) obtain the expiration or termination of the waiting period under the HSR Act, or any other applicable antitrust, competition, or trade regulation Law, applicable to the Transactions, (ii) avoid the entry of, the commencement of litigation seeking the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order that would materially delay or prevent the consummation of the Transactions, or (iii) obtain all authorizations, consents, orders and approvals of Governmental Authorities necessary for the consummation of the Transactions, including any authorizations, consents, orders or approvals required by any Health Care Law or Government Program.

(e) With respect to any stockholder litigation against the Company and/or its directors relating to the Transactions, Company shall (i) promptly notify Parent of the initiation of any such litigation, (ii) promptly notify Parent of any material communication or development with respect to such litigation and (iii) consult in good faith with Parent with respect to any material decisions and the Company’s general strategy regarding such litigation.

SECTION 6.08 Obligations of Parent and Merger Sub. Parent shall take all action necessary to cause Merger Sub to perform its obligations under this Agreement and to

consummate the Transactions on the terms and subject to the conditions set forth in this Agreement.

SECTION 6.09 Public Announcements. The initial press release relating to this Agreement shall be a joint press release the text of which has been agreed to by each of Parent and the Company. Thereafter, each of Parent and the Company shall consult with each other before issuing any press release or otherwise making any public statements with respect to this Agreement or any of the Transactions, except to the extent public disclosure is required by applicable Law or the requirements of the Nasdaq Stock Market, in which case the issuing party shall use its reasonable best efforts to consult with the other party before issuing any press release or making any such public statements, and except with respect to the matters described in Sections 6.03, 8.01 and 8.03.

SECTION 6.10 Transfer Taxes. The Company and Parent shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any sales, transfer, stamp, stock transfer, value added, use, real property transfer or gains and any similar Taxes which become payable in connection with the Transactions.

(c) The Company Termination Fee and/or Expense Reimbursement payable by the Company under this Section 8.03 shall be paid to Parent or its designee by the Company in immediately available funds as follows:

(i)in the case of Section 8.03(b)(iv), the applicable payment shall be made concurrently with and as a condition to the effectiveness of a termination of this Agreement by the Company pursuant to Section 8.01(f);

(ii) in the case of Section 8.03(b)(ii)(A) or Section 8.03(b)(iii), the applicable payment shall be made on or prior to the date of the event giving rise to the obligation to make such payment; and

(iii) in the case of Section 8.03(b)(i), Section 8.03(b)(ii)(B) or Section 8.03(b)(v), (x) if the event giving rise to the obligation to make such payment is the Company entering into, or submitting to the stockholders of the Company for adoption, an agreement with respect to, or consummating, any Acquisition Proposal with a Competing Bidder, the applicable payment shall be made on or prior to the date of such event or (y) if the event giving rise to the obligation to make such payment is the Company entering into, or submitting to the stockholders of the Company for adoption, an agreement with respect to, or consummating, any Acquisition Proposal with any person other than a Competing Bidder, the applicable payment shall be made on or prior to the consummation of any Acquisition Proposal.

Notwithstanding anything to the contrary in this Agreement, the payment to Parent or its designees of the Company Termination Fee and/or the Expense Reimbursement shall be the sole

and exclusive remedy of Parent for any loss suffered by Parent or Merger Sub as a result of the failure of the Merger and the other Transactions to be consummated and upon such payment in accordance with this Section 8.03, the Company shall not have any further liability or obligation relating to or arising out of this Agreement or the Transactions (except in the case of fraud or a breach by the Company of this Agreement).

(d) The Company acknowledges and agrees that the agreements contained in subsections (b) and (c) of this Section 8.03 are an integral part of the Transactions, and that, without these agreements, Parent would not have entered into this Agreement; accordingly, if the Company fails to pay any amounts due and payable pursuant to subsections (b) and (c) of this Section 8.03, and, in order to obtain such payment, Parent commence a suit that results in a judgment against the Company for the Company Termination Fee or the Expense Reimbursement, the Company shall pay to Parent their costs and expenses (including attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the Company Termination Fee or Expense Reimbursement, as the case may be, from the date such payment was required to be made until the date of payment at the prime rate of JPMorgan Chase Bank, N.A. in effect on the date such payment was required to be made.

(e) For purposes of this Section 8.03, Acquisition Proposal shall have the meaning assigned to such term in Section 6.03(d), except that references to 15% in clauses (1) and (2) of the definition thereof shall be deemed to be references to 50% and clause (3) of the definition thereof shall be deemed amended and replaced in its entirety by the following language: “(3) any merger, consolidation, business combination, recapitalization or other similar transaction involving the Company pursuant to which stockholders of the Company immediately prior to the consummation of such transaction would cease to own directly or indirectly at least 50% of the voting power of the outstanding securities of the Company (or of another person that directly or indirectly would own all or substantially all the assets of the Company) immediately following such transaction in the same proportion as they owned prior to the consummation of such transaction.”

(c) When a reference is made in this Agreement to Sections, Schedules or Exhibits, such reference shall be to a Section, Schedule or Exhibit of this Agreement, respectively, 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 any particular provision of this Agreement. The term “or” is not exclusive. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. References to a person are also to its permitted successors and assigns. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms.

SECTION 9.04 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 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 hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the Transactions be consummated as originally contemplated to the fullest extent possible.

SECTION 9.05 Disclaimer of Other Representations and Warranties. Parent, Merger Sub and the Company each acknowledges and agrees that, except for the representations and warranties expressly set forth in this Agreement (a) no party makes, and has not made, any representations or warranties relating to itself or its businesses or otherwise in connection with the Transactions, (b) no person has been authorized by any party to make any representation or warranty relating to such party or its businesses or otherwise in connection with the Transactions and, if made, such representation or warranty must not be relied upon as having been authorized by such party, and (c) any estimates, projections, predictions, data, financial information, memoranda, presentations or any other materials or information provided or addressed to any party or any of its Representatives are not and shall not be deemed to be or to include representations or warranties unless any such materials or information is the subject of any representation or warranty set forth in this Agreement.

SECTION 9.06 Entire Agreement; Assignment. This Agreement and the Confidentiality Agreement constitute the entire agreement among the parties hereto with respect to the subject matter hereof and thereof and supersede all prior agreements and undertakings, both written and oral, among the parties hereto, or any of them, with respect to the subject matter hereof and thereof. This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise), except that Parent and Merger Sub may assign all or any of their

rights and obligations hereunder to any direct or indirect wholly owned Subsidiary of Parent; provided, however, that no such assignment shall relieve the assigning party of its obligations hereunder if such assignee does not perform such obligations.

SECTION 9.07 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and 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, other than Section 6.04 (which is intended to be for the benefit of the persons covered thereby and may be enforced by such persons) and except for the right of (i) the Company, on behalf of the holders of equity interests in the Company, to pursue damages (which the parties acknowledge and agree shall not be limited to reimbursement of expenses or out-of-pocket costs, and may include claims for damages based on the consideration that would have otherwise been payable to the stockholders of the Company and other relevant matters, including other combination opportunities and the time value of money), which shall be deemed in such event to be damages of holders of equity interests in the Company, in the event of a failure by Parent or Merger Sub to consummate the Merger as required by this Agreement, which right is hereby acknowledged and agreed by Parent and Merger Sub and (ii) Parent to pursue damages (which the parties acknowledge and agree shall not be limited to reimbursement of expenses or out-of-pocket costs, and may include claims for damages based on the synergies and other benefits that would have otherwise accrued to Parent and other relevant matters), which shall be deemed in such event to be damages of holders of equity interests in Parent, in the event of a failure by the Company to consummate the Merger as required by this Agreement, which right is hereby acknowledged and agreed by the Company. For purposes of this Agreement, any action of the Special Committee shall be binding upon and shall constitute an act of the Company.

SECTION 9.08 Remedies; Specific Performance; Expenses. The parties hereto acknowledge and agree that the parties would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached and that any non-performance or breach of this Agreement by any party hereto could not be adequately compensated by monetary damages alone and that the parties hereto would not have any adequate remedy at law. Accordingly, in addition to any other right or remedy to which each party may be entitled, at law or in equity (including monetary damages), such party shall be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement without posting any bond or other undertaking. Notwithstanding anything to the contrary in this Agreement, all Expenses of the Company, Parent and Merger Sub incurred in connection with any Action brought by the Company, Parent or Merger Sub relating to the terms and provisions of this Agreement provided for in the foregoing sentence shall be paid by the Company in the event that Parent is successful on the merits in such Action and shall be paid by Parent in the event that the Company is successful on the merits in such Action.

SECTION 9.09 Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware applicable to contracts executed in and to be performed in that State. All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in the Delaware Court of Chancery (or any

proper appellate court thereof). The parties hereto hereby (a) submit to the exclusive jurisdiction of the Delaware Court of Chancery for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto, and (b) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the courts described above, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the Transactions may not be enforced in or by the courts described above.

SECTION 9.10 Waiver of Jury Trial. Each of the parties hereto hereby waives to the fullest extent permitted by applicable Law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement or the Transactions. Each of the parties hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter into this Agreement and the Transactions, as applicable, by, among other things, the mutual waivers and certifications in this Section 9.10.

SECTION 9.11 Amendment. This Agreement may be amended by the parties hereto 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 adoption of this Agreement and the Transactions by the stockholders of the Company, no amendment shall be made except as allowed under applicable Law. This Agreement may not be amended except by an instrument in writing signed by each of the parties hereto.

SECTION 9.12 Waiver. At any time prior to the Effective Time, any party hereto may (a) extend the time for the performance of any obligation or other act of any other party hereto, (b) waive any inaccuracy in the representations and warranties of any other party contained herein or in any document delivered pursuant hereto, and (c) waive compliance with any agreement of any other party or any condition to its own obligations contained herein. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the party or parties to be bound thereby. 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 9.13 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 9.14 Counterparts. This Agreement may be executed and delivered (including by facsimile transmission) in two or more counterparts, and by the different parties hereto 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.
