Upon the terms and subject to the conditions of this Agreement, at the Closing, Seller shall sell, transfer, assign, convey and deliver to Buyer, and Buyer shall purchase and accept from Seller, legal and beneficial ownership of all of the Units owned by Seller, free and clear of all Encumbrances.

(a) The purchase price (the “Purchase Price”) for the Units shall be equal to:

At Closing, Buyer shall deliver the Escrow Amount to Escrow Agent to be held by Escrow Agent pursuant to the terms of the Escrow Agreement (herein so called) in a form mutually agreeable to the Parties and the Escrow Agent. Within five (5) days of April 30, 2013 (the “Escrow Release Date”), Seller shall be entitled to receive all of the remaining Escrow Amount, plus any interest thereon, less a reasonable estimate of potential Losses relating to claims pursuant to Article XI for which a valid Claim Notice has been submitted by Buyer in accordance with Section 11.3 (each an “Unresolved Claim”). From time to time promptly after final resolution of any Unresolved Claim, Seller and Buyer will instruct the Escrow Agent to disburse to Seller or Buyer, as appropriate, amounts held by the Escrow Agent in respect of such Unresolved Claim.

The expenses of the Escrow Agent shall be paid fifty percent (50%) by Buyer and fifty percent (50%) by Seller (“Seller Escrow Expense”). The Seller Escrow Expense shall be deducted from any portion of the Escrow Amount that is payable to Seller and retained by the Escrow Agent prior to the distribution of the balance, if any, to Seller.

(a) The Purchase Price is based, in part, on the Group Companies having an aggregate Working Capital of Two Million Three Hundred Thousand and 00/100 Dollars ($2,300,000.00)at the Closing (the “Working Capital Target”). Accordingly, the Purchase Price is subject to adjustment pursuant to the procedures set forth in this Section 2.3 (the “Purchase Price Adjustments”) if, as of the Closing Date, the aggregate Working Capital of the Group Companies is greater or less than the Working Capital Target. Exhibit 2.3(a) sets forth an example calculation of the Group Companies’ Working Capital that illustrates how the Group Companies’ Working Capital shall be calculated for the purposes of this Agreement.

(b) Not later than three (3) Business Days prior to the Closing Date, Seller shall deliver to Buyer its good faith estimate of (i) the Working Capital (the “Estimated Closing Working Capital”) as of immediately prior to the Closing, (ii) the Cash and Cash Equivalents, and (iii) the Closing Indebtedness, all in reasonable detail prepared in accordance with GAAP.

(c) As promptly as practicable (but not later than forty-five (45) calendar days) following the Closing Date, Buyer shall:

(i) prepare a consolidated balance sheet of the Group Companies as of the Closing Date, reflecting Buyer’s good faith estimate of the Closing Date Balance Sheet (the “Preliminary Closing Date Balance Sheet”), which Preliminary Closing Date Balance Sheet shall (A) be prepared in accordance with GAAP and (B) fairly present Buyer’s good faith estimate of the value of the consolidated assets and liabilities of the Group Companies as of the Closing Date; and

(d) Seller may, within forty-five (45) calendar days after the date of receipt of the Preliminary Closing Date Balance Sheet and Preliminary Working Capital Determination, deliver to Buyer a written statement setting forth its objections thereto. In the event Seller does not so object within such forty-five (45) day period, the Preliminary Closing Date Balance Sheet and Preliminary Working Capital Determination shall be final and binding as the “Closing Date Balance Sheet” and “Closing Working Capital”, respectively, for purposes of this Agreement. In the event Seller so objects within such forty-five (45) day period, Buyer and Seller shall use their reasonable efforts to resolve, in good-faith, by written agreement (the “Agreed Adjustments”) any differences as to the Preliminary Closing Date Balance Sheet and Preliminary Working Capital Determination and, in the event Seller and Buyer so resolve any such differences, the Preliminary Closing Date Balance Sheet and Preliminary Working Capital Determination, in each case as adjusted by the Agreed Adjustments, shall be final and binding as the Closing Date Balance Sheet and Closing Working Capital, respectively, for purposes of this Agreement. In the event any objections raised by Seller are not resolved by Agreed Adjustments within thirty (30) calendar days after Seller advises Buyer of Seller’s objections, then Buyer and Seller shall submit the objections that are then unresolved to and jointly engage a national accounting firm acceptable to both Buyer and Seller and such firm (the “Accounting Firm”) shall be directed by Buyer and Seller to resolve the unresolved objections as promptly as reasonably practicable, but in no event later than sixty (60) calendar days after the Accounting Firm’s appointment, and to deliver written notice to each of Buyer and Seller setting forth its resolution of the disputed matters. The Accounting Firm may only review the items that are in dispute and resolve the dispute in accordance with the requirements of this Section 2.3. In connection with the resolution of such dispute, the Accounting Firm will allow Buyer and Seller to present their respective positions regarding each item that is in dispute, with concurrent copies to the other. The Accounting Firm may, in its discretion, conduct a conference concerning the dispute, at which conference Buyer and Seller may present additional documents, materials and other information and have present their respective advisors, counsel and accountants. The Preliminary Closing Date Balance Sheet and Preliminary Working Capital Determination, in each case after giving effect to any Agreed Adjustments and to the resolution of disputed matters by the Accounting Firm, shall be final and binding as the “Closing Date Balance Sheet” and “Closing Working Capital”, respectively, for purposes of this Agreement. Notwithstanding anything in this Agreement to the contrary, no Party may assert that any award issued by the Accounting Firm is unenforceable because it has not been timely rendered.

(e) The Parties shall make available to Buyer and Seller and, if applicable, the Accounting Firm, such books, records and other information (including work papers) as any of the foregoing may reasonably request in order to review the Estimated Closing Balance Sheet, the Preliminary Closing Date Balance Sheet, the Estimated Closing Working Capital and Preliminary Working Capital Determination, respectively, or any matters submitted to the Accounting Firm. Buyer and Seller shall bear the fees and disbursements of the Accounting Firm in the same proportion that the aggregate dollar amount of the disputed items submitted to the Accounting Firm that are unsuccessfully disputed by each such Party bears to the total dollar amount of such disputed items so submitted (as determined by the Accounting Firm in its sole discretion); provided that, until such determination is made, the fees and disbursements of the Accounting Firm shall be borne fifty percent (50%) by Buyer, on the one hand, and fifty percent (50%) by Seller, on the other, with the Parties reimbursing one another, if necessary, following such determination. All other costs and expenses incurred by the Parties hereto in connection with resolving any dispute hereunder before the Accounting Firm shall be borne by the party incurring such cost and expense.

SELLER HEREBY EXPRESSLY DISCLAIMS ANY OTHER EXPRESS OR IMPLIED REPRESENTATIONS OR WARRANTIES WITH RESPECT TO ANY MATTER WHATSOEVER.

(b) Without limiting the generality of the foregoing, none of Seller, any Group Companies nor any Affiliate or Representative thereof has made, and shall not be deemed to have made, any representations or warranties in the materials relating to the business of the Group Companies made

available to Buyer, including due diligence materials, or in any presentation of the business of the Group Companies by management of Seller or others in connection with the Contemplated Transactions, and no statement contained in any of such materials or made in any such presentation shall be deemed a representation or warranty hereunder or otherwise or deemed to be relied upon by Buyer in executing, delivering and performing this Agreement and the Contemplated Transactions. It is understood that any cost estimates, projections or other predictions, any data, any future financial information or any memoranda or offering materials or presentations, including but not limited to, any confidential information memorandum or similar materials made available by Seller, the Group Companies or their Affiliates or Representatives are not and shall not be deemed to be or to include representations or warranties of Seller, and are not and shall not be deemed to be relied upon by Buyer in executing, delivering and performing this Agreement and the Contemplated Transactions.

6.1. Organization. Buyer is a limited liability company duly organized, validly existing and in good standing under the Laws of the State of Delaware. Buyer is duly licensed or qualified to conduct business as a foreign limited liability company and is in good standing in each jurisdiction where the character of its properties owned or held under lease or the nature of its activities makes such qualification necessary, except where the failure to be so qualified or in good standing, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on Buyer or its operations. Buyer has all necessary corporate power and authority to own or lease and operate its assets and to carry on its business in the manner that it has been and is currently conducted.

6.2. Authorization, Validity and Effect of Agreement.

This Agreement has been duly authorized by the governing board of Buyer and duly executed and delivered by Buyer and is (assuming the valid authorization, execution and delivery of this Agreement by Seller) the legal, valid and binding obligation of Buyer enforceable in accordance with its terms, and each of the Buyer Ancillary Agreements has been duly authorized by the governing board of Buyer and, upon execution and delivery thereof by Buyer, will be duly executed and delivered by Buyer, and will be (assuming the valid authorization, execution and delivery by Seller, where Seller is a party, or the other party or parties thereto) a legal, valid and binding obligation of Buyer, enforceable in accordance with its terms, in each case subject to bankruptcy, insolvency, reorganization, moratorium and similar Laws of general application relating to or affecting creditors’ rights and to general equity principles. No other action on the part of Buyer or its members or managers is necessary to authorize the execution and delivery by Buyer of this Agreement and the Buyer Ancillary Agreements to which Buyer is a party, the performance of Buyer’s obligations hereunder or thereunder or the consummation by Buyer of the Contemplated Transactions.

6.3. No Conflicts; Consents and Approvals. The execution and delivery of, and the performance of its obligations under, this Agreement by Buyer do not, and the consummation by Buyer of the Contemplated Transactions or by any of the Buyer Ancillary Agreements will not:

(a) assuming the receipt of all necessary authorizations, consents, approvals, orders and waivers and the filing of all necessary documents as described in Section 6.3(b), with or without the giving of notice, lapse of time or both, conflict with, result in a violation or breach of the terms,

conditions or provisions of, or constitute a default, an event of default or an event creating rights of acceleration, termination or cancellation or a loss of rights under, (i) the Certificate of Formation, Operating Agreement or other governing documents of Buyer, (ii) any contract to which Buyer is a party or by which Buyer or any of its assets, properties or businesses may be subject or bound, (iii) any Governmental Order to which Buyer is a party or by which Buyer or any of its assets, properties or businesses may be subject or bound or (iv) any material Laws or Governmental Permits applicable to Buyer or any of its assets, properties or businesses, other than, in the case of clause (ii) above, any such conflicts, violations, breaches, defaults, rights or loss of rights that, individually or in the aggregate, would not reasonably be expected to adversely affect in any material respect the ability of Buyer to enter into, perform its obligations under and consummate the Contemplated Transactions; or

(b) require the authorization, consent, approval, order, waiver or act of, or the making by Buyer of any declaration, filing or registration with or notice to, any Person, except (i) in connection, or in compliance, with the provisions of the HSR Act, and (ii) such authorizations, consents, approvals, orders, waivers, acts of, declarations, filings, registrations or notices the failure of which to be obtained or made, individually or in the aggregate, would reasonably be expected to adversely affect in any material respect the ability of Buyer to enter into, perform its obligations under and consummate the Contemplated Transactions.

(a) There are no Proceedings pending or, to the actual knowledge of Buyer, threatened against Buyer or its Affiliates, or any of their respective officers, directors, employees, consultants or agents (in their capacity as such), in each case, that, individually or in the aggregate, would reasonably be expected to adversely affect in any material respect the ability of Buyer to enter into, perform its obligations under and consummate the Contemplated Transactions.

(b) There are no Proceedings pending or, to the actual knowledge of Buyer, threatened against Buyer or its Affiliates that questions the legality of the Contemplated Transactions, or which seeks to restrain, enjoin or delay the consummation of the Contemplated Transactions, or which seeks damages in connection herewith or therewith, and no injunctions of any type have been entered or issued in connection with the Contemplated Transactions.

Buyer has no reasonable basis to believe that any Governmental Orders or restrictions are contemplated or that its current assets or activities make any such Governmental Orders or restrictions reasonably likely to result as a result of the execution of this Agreement or otherwise, prior to the Closing.

6.5. Financing. Buyer has cash on hand and other immediately available sources of funds that, together, will at the Closing be sufficient to effect the Contemplated Transactions, including payment of the Purchase Price and other amounts required to be paid under Section 3.2, pay all associated fees, costs and expenses and to make all other payments required by the terms hereof and to otherwise consummate the Contemplated Transactions. Notwithstanding anything to the contrary contained herein, Buyer acknowledges and agrees that it shall not be a condition to the obligations of Buyer to consummate the transactions contemplated hereby that Buyer have sufficient funds for payment of all amounts due hereunder.

(a) Buyer is acquiring the Units as an investment for its own account and not with a view to the distribution thereof.

7.1. Access to Information. Seller agrees to provide Buyer with reasonable access to all information in the possession of Seller or Representatives relating to the Group Companies or the Contemplated Transactions, and all of such information shall be treated as Confidential Information pursuant to the terms of the Confidentiality Agreement, and Buyer agrees to maintain the confidentiality of the proposed transaction in all dealings with employees of Seller or the Group Companies. Seller shall not be required to provide such access if to do so would unreasonably interfere with the operations of the Group Companies or delivery of patient care and shall not be required to violate any obligation of confidentiality to which it is subject or to waive any privilege that it may possess in discharging its obligations pursuant to this Section 7.1, so long as Seller shall have used its commercially reasonable efforts to provide such information without violation of any such obligation or applicable Law. Buyer agrees that such investigation shall be conducted in such a manner as not to interfere unreasonably with the operations of the Group Companies. Buyer also agrees that it is not authorized to and shall not (and shall not permit any of its employees, agents, representatives or Affiliates to) contact any employee (other than executive officers), payor, supplier, vendor, customer, patient or other material business relation of the Group Companies regarding the Contemplated Transactions prior to the Closing, without the prior consent of Seller. Further, Buyer agrees that neither it nor any of its Representatives will visit any Group Company unless accompanied by a Representative of Seller (or unless Seller authorizes a visit without a Representative of Seller).

(a) Each Party will act diligently and use its best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other Parties in doing, all things necessary, proper and advisable to consummate and make effective the Contemplated Transactions as promptly as practicable, including: (i) obtaining, before the Closing Date, all authorizations, consents,

approvals, orders and waivers, in form and substance reasonably satisfactory to the other Parties, required, or that may become necessary, to be obtained from any Person or Governmental Body to consummate the Contemplated Transactions; and (ii) causing the satisfaction of all conditions to the Closing; provided, however, that such action shall not include any requirement of Seller or any of its Affiliates to pay money to any third party, commence or participate in any litigation or offer or grant any accommodation (financial or otherwise) to any third party.

Each of the Parties shall use its reasonable best efforts to take such action as may be required, including responding to any Request for Additional Information or Documentary Material received by the FTC or DOJ pursuant to the HSR Act and actions relating to the same, to cause the expiration of the waiting periods or the receipt of approval decisions under the HSR Act with respect to the Contemplated Transactions as promptly as reasonably practicable.

No Party shall agree to participate in any meeting or conference with any Governmental Body in respect of any filing, investigation or other inquiry unless it consults with the other Party in advance and, to the extent permitted by such Governmental Body, gives the other Party the opportunity to attend and participate at such meeting or conference. Buyer and Seller shall equally share all filing fees under the HSR Act with respect to the Contemplated Transactions.

(c) As promptly as reasonably practicable after the date hereof (but in any event by the close of business on January 17, 2012), Buyer shall (or shall cause Acadia to) file with the Oklahoma State Board of Health any notifications and other information required to be filed with respect to the Contemplated Transactions.

From and after the date of this Agreement until the earlier of the termination of this Agreement or the Closing Date, Seller may prepare and deliver to Buyer supplements and/or amendments to the Schedules, which may contain additional Sections that are not in existence as of the date hereof relating to any of the provisions contained in Article IV or V, with respect to matters first arising after the date hereof (each, an “Update”), and each such Update shall be deemed to be an amendment to this Agreement for all purposes hereof other than for purposes of the conditions set forth in Section 9.1; provided that, in the event that the disclosure of the facts, circumstances and events included in such Update would give Buyer the right to elect to terminate this Agreement pursuant to Section 12.1(b) if the 30-day cure period described therein had lapsed and Buyer does not make such election within five (5) Business Days of its receipt of such Update, such Update shall be deemed to be an amendment to this Agreement for all purposes hereof, including with respect to the conditions set forth in Section 9.1. Notwithstanding the above, no update shall prejudice Buyer’s rights to indemnification under Sections 11.1(a)(iii)-(v).

7.6. Exclusivity. During the period from the date of this Agreement through the earlier of the Closing or the termination of this Agreement in accordance with its terms, Seller shall not take, nor shall it permit any of its Affiliates or Representatives to take, any action to solicit, encourage, initiate or engage in discussions or negotiations with, or provide any information to, or enter into any agreement with, any Person (other than Buyer and/or its Affiliates and Representatives) concerning any direct or indirect acquisition of all or substantially all of the Capital Stock or assets of any Group Company, or any

merger, consolidation or other business combination involving any Group Company (each, an “Acquisition Transaction”), and Seller and its Affiliates and Representatives shall immediately cease and cause to be terminated all existing discussions, negotiations and other communications with any Person (other than Buyer and its Affiliates and Representatives) with respect to any such Acquisition Transaction; provided, however, that Buyer hereby acknowledges that prior to the date of this Agreement, Seller and its Affiliates and Representatives have provided information relating to the Group Companies and has afforded access to, and engaged in discussions with, other Persons in connection with a proposed Acquisition Transaction and that such information, access and discussions could reasonably enable another Person to form a basis for an Acquisition Transaction without any breach by Seller of this Section 7.6. During the period from the date of this Agreement through the earlier of the Closing or the termination of this Agreement in accordance with its terms, Seller shall notify Buyer promptly upon the receipt of any proposal, offer, inquiry or contact from any Person (other than Buyer or its Affiliates and Representatives) in respect of any Acquisition Transaction.

Seller shall cooperate with Buyer in the preparation and filing of building plans and otherwise take, and/or cause the Group Companies to take, any actions required of Seller or the Group Companies prior to Closing in order to meet all requirements of the Expansion CON.

7.8. Risk of Loss. From the date hereof until the Closing Date, in the event that there is any damage to or loss of any of the assets of a Group Company in excess of One Hundred Thousand Dollars ($100,000) (whether by fire, theft, vandalism or other cause or casualty), the Purchase Price shall be reduced by the amount necessary to repair the damage (“Damage Repair Amount”), which reduction shall be offset by any amounts paid by Seller’s insurance company and assigned to Buyer and received by Buyer by the Closing Date; provided, however, in the event of a casualty constituting a Group Companies Material Adverse Effect, Buyer, at its sole option, may elect to terminate this Agreement in its entirety. If Seller and Buyer are unable to agree as to the Damage Repair Amount, then such amount shall be determined by an MAI appraiser to be mutually selected and paid equally by Seller and Buyer. If Seller and Buyer are unable to mutually select an appraiser, then one MAI appraiser shall be selected and paid by Buyer and one MAI appraiser shall be selected and paid by Seller. If a party does not select an appraiser as provided in the preceding sentence within ten (10) days after the other party has given notice of the name of its appraiser, such party shall lose its right to appoint an appraiser. If the two appraisers are selected by the parties as provided above, they shall meet promptly to determine the reduction in Purchase Price. If they are unable to agree within fifteen (15) days after the second appraiser has been selected, they shall jointly select a third MAI appraiser. The reduction in Purchase Price shall be set by agreement of any two of the three appraisals. If the two appraisers are unable to agree on a third appraiser within thirty (30) days after the second appraiser has been selected, either party, by giving written notice to the other, may apply to the American Arbitration Association for the purpose of determining the reduction in Purchase Price. Seller and Buyer shall each bear one-half (1/2) of the cost of selecting the third appraiser and of paying the third appraiser’s fee. The third appraiser, however selected, shall be a person who has not previously acted in any capacity for either party. If any two appraisers are unable to determine the reduction in Purchase Price within fifteen (15) days after the third appraiser has been selected, then the two appraisals that are closest shall be added together and their total divided by two; the resulting quotient shall be the reduction in Purchase Price (the third appraisal farthest from the remaining two shall be ignored). In determining the reduction in Purchase Price, each appraiser shall take into consideration, understand, and correctly employ those recognized techniques that are necessary to produce a credible appraisal.

7.9. Condemnation. From the date hereof until the Closing Date, in the event that there is any condemnation of any of the assets of a Group Company in excess of One Hundred Thousand Dollars ($100,000), the Purchase Price shall be reduced by the amount of such condemnation proceeds but the

reduction shall be offset by any amounts received by Buyer for such condemnation; provided, however, in the event of any pending, threatened or contemplated condemnation or eminent domain proceeding which constitutes a Group Companies Material Adverse Effect, Buyer at its sole option, may elect to terminate this Agreement in its entirety.

7.10. Title Work and Surveys; Defects and Cure; Title Policy; Environmental Inspections.

(a) Title Work. Seller has furnished to Buyer the title work listed on Schedule 7.10 (the “Existing Title Work”). Within forty-five (45) days following the date of this Agreement, Buyer may, at Buyer’s option and expense, obtain commitments from the title insurance company issuing the Existing Title Work (the “Title Company”) to issue (i) updates to the Existing Title Work or (ii) new policies of owner’s title insurance for those portions of the Owned Real Property as to which there is no Existing Title Work, together with legible copies of all exceptions to title referenced therein (the “New Title Work”). The New Title Work shall commit to insure title as of each commitment’s effective date to the Owned Real Property subject to all exceptions stated in the New Title Work or conditions to such title, which would appear in an owner’s title policy of title insurance, if issued. Buyer shall furnish Seller with copies of any New Title Work promptly following receipt of same.

(b) Surveys. Seller has furnished to Buyer the as-built surveys of the Owned Real Property listed on Schedule 7.10 (the “Existing Surveys”). Within forty-five (45) days following the date of this Agreement, Buyer may, at Buyer’s option and expense, obtain (i) updates to the Existing Surveys or (ii) current, as-built surveys for those portions of the Owned Real Property as to which there are no Existing Surveys (the “New Surveys”) meeting the 2011 Minimum Standard Detail Requirements for ALTA/ACSM Land Title Survey of comparable properties, including such Table A optional items as Buyer elects. The New Surveys contain the surveyor’s ALTA/ACSM certification to Buyer, Seller, the Group Companies and the Title Company. Buyer shall furnish Seller with copies of any New Surveys promptly following receipt of such surveys.

(c) Defects and Cure. The New Title Work and the New Surveys are collectively referred to as “Title Evidence”. Buyer shall notify Seller in writing (“Defect Notice”) within ten (10) days after its receipt of the last of the Title Evidence of any claims, Encumbrances, exceptions or defects disclosed in the Title Evidence, other than Permitted Encumbrances, which would reasonably be expected to materially and adversely affect the use or operation of a Facility or Facilities in the manner in which such Facility or Facilities have historically been operated by Seller and to which Buyer objects (the “Defects”) in a duly given Defect Notice. For purposes of this Agreement, (i) any Encumbrance reflected on any Existing Survey or Existing Title Work shall be deemed a Permitted Encumbrance, and (ii) any Encumbrance reflected in the New Title Work and New Title Evidence not referenced in the Defect Notice shall be deemed a Permitted Exception. Seller shall use commercially reasonable efforts to cure any Defect identified in a Defect Notice. Should Seller, notwithstanding the use of commercially reasonable efforts, not have cured by Closing any Defects referenced in a Defect Notice, and the failure to cure such Defect(s) shall reasonably be expected to have a Group Companies Material Adverse Effect, then Seller may elect to either terminate this Agreement, in which event neither Seller nor Buyer shall have any further obligation to the other hereunder except those obligations which by the express terms of this Agreement shall survive any such termination or, waive such right to terminate this Agreement, and, in such event, such Defects as to which Buyer shall have waived its right to terminate shall be deemed Permitted Encumbrances for all purposes under this Agreement. A cure of a Defect for purposes of this Section 7.10 shall include an endorsement by the Title Company reasonably acceptable to Buyer, either eliminating the Defect, insuring over the Defect or insuring against the effect of the Defect.

(d) Title Policy. At the Closing, Buyer may obtain a current ALTA Form Owner’s Policy of Title Insurance (the “Title Policies”) for the Owned Real Property issued by the Title Company. The Title Policies shall be issued as of the Closing Date in an amount equal to the portion of the Purchase Price being allocated to such portion of the Owned Real Property and shall insure to the applicable Group Company good and marketable fee simple title, subject to such exceptions, as may be contained in the Title Policies, as the case may be, to such Owned Real Property. Seller and the Group Companies shall grant their reasonable cooperation to Buyer in executing such certificates and affidavits as the Title Company shall reasonably and customarily require as a condition to issuance of the Title Policies; provided however that Seller’s cooperation and provision of any affidavit or certificate as contemplated by the foregoing is intended merely as an accommodation to Buyer, and that it shall neither be an obligation of the Seller and Group Companies to issue an “owner’s affidavit” (of the type that would otherwise be required in connection with “extended coverage” under the Title Policies) or to otherwise undertake any material obligation or liability in connection with the issuance of the Title Policies nor a condition to Buyer’s obligations to Closing that the Title Company issue the Title Policies, it being understood and agreed that the sole extent of Seller’s obligations with respect to matters of title of the Owned Real Property are those obligations expressly set forth in subsection (c) above, and no further or otherwise. Buyer shall pay all premiums, costs and expenses of the Title Policies.

(e) Environmental Inspections. Seller has provided Buyer with the Existing Environmental Reports listed on Schedule 7.10 (the “Existing Environmental Reports”). Within fifteen (15) days following the execution of this Agreement, Seller shall cause the preparer of the Existing Environmental Reports to provide by amendment thereto, or by a reliance letter reasonably satisfactory to Buyer, that Buyer and the applicable Group Companies shall be deemed a party to and may rely upon the Existing Environmental Work and shall have the benefit of the insurance coverage for the Existing Environmental Work provided by the preparer. For a period of forty-five (45) days following the execution of this Agreement (the “Environmental Inspection Period”), Buyer and Buyer’s agents, representatives and contractors shall have the right to enter upon the Owned Real Property for the purpose of conducting such tests, assessments, evaluations and investigations as Buyer may determine in its sole discretion, in order to evaluate and determine the current environmental condition of the Owned Real Property, including without limitation Phase I or Phase II environmental assessments of any Owned Real Property not covered by the Existing Environmental Reports (or, if Seller is unable to provide the assurances set forth above as to the Existing Environmental Reports, all of the Owned Real Property) and updates of any existing Phase I or Phase II assessments in order to bring them current under AAI standards for CERCLA. Within five (5) days after the expiration of the Environmental Inspection Period, Buyer shall give written notice to Seller of any breach of Section 5.19, which would reasonably be expected to materially and adversely affect the use or operation of a Facility or Facilities in the manner in which such Facility or Facilities have historically been operated by Seller (“Environmental Conditions”). Buyer shall provide Seller with a copy of Buyer’s Environmental Inspections reflecting such Environmental Conditions. If Buyer gives notice of any Environmental Conditions to Seller, and if such Environmental Conditions constitute a breach of Section 5.19, Seller shall use commercially reasonable efforts to cure any Defect identified in a Defect Notice. Should Seller, notwithstanding the use of commercially reasonable efforts, not have cured by Closing any such Environmental Conditions referenced in the Buyer’s Environmental Inspections, and the failure to cure such Environmental Condition(s) shall reasonably be expected to have a Group Companies Material Adverse Effect, then Seller may elect to either terminate this Agreement, in which event neither Seller nor Buyer shall have any further obligation to the other hereunder except those obligations which by the express terms of this Agreement shall survive any such termination or, waive such right to terminate this Agreement.

(a) Notwithstanding anything herein to the contrary, Buyer shall be liable for and pay, and shall indemnify Seller against, any Transfer Taxes that may be imposed upon, or payable or collectible or incurred in connection with this Agreement and the Contemplated Transactions. Buyer shall file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes, and if required by applicable Law, Seller will join in the execution of any such Tax Returns or other documentation.

(b) After the Closing, the Parties shall cooperate with each other by furnishing any additional information and executing and delivering any additional documents as may be reasonably requested by such Parties in their preparation of any Tax Returns required to be filed by or with respect to the Group Companies. Such cooperation shall include access during normal business hours afforded to the Parties and their respective agents and Representatives to, and reasonable retention by such Parties of, Tax records related to the Group Companies, and making employees and agents (including auditors) of the Group Companies available on a reasonably convenient basis to provide additional information and explanation of any material provided hereunder.

(c) Except as set forth on Schedule 8.1(c), neither Seller nor any Affiliate of Seller shall file or cause or permit to be filed any amended Tax Return or claims for refund with respect to the Group Companies or which include the Group Companies or grant or cause or permit to be granted any extension of any statute of limitation with respect to any Tax Returns for any Pre-Closing Tax Period without the prior written consent of the Buyer (which consent shall not be unreasonably withheld or delayed). None of Buyer, the Group Companies or any Affiliate of Buyer shall (or shall cause or permit any Group Company to) amend, refile or otherwise modify (or grant an extension of any statute of limitation with respect to) any Tax Return relating in whole or in part to any Group Company with respect to any Taxable Period or portion of any Straddle Period ending on or prior to the Closing Date without the prior written consent of Seller (which consent shall not be unreasonably withheld, conditioned or delayed).

(d) Buyer shall prepare or cause to be prepared, in a manner consistent with the most recent Tax Returns of the Group Companies and no position shall be taken, election made or method adopted that is inconsistent with positions taken, elections made or methods used in prior periods in filing such Tax Returns (unless Buyer determines there is no reasonable basis for such position, election or method), all Tax Returns of or with respect to the Group Companies that are required to be filed after the Closing Date for (i) all Taxable Periods ending on or prior to the Closing Date and (ii) all Straddle Periods; provided that Buyer shall deliver any such Tax Return to Seller in the form proposed for filing at least twenty (20) Business Days prior to the due date thereof for review and approval by Seller, which approval may not be unreasonably withheld, conditioned or delayed. Seller shall notify Buyer of any requested changes to such returns within seven (7) Business Days of Seller’s receipt thereof. If Buyer objects to Seller’s requested changes, Buyer and Seller will have five (5) Business Days to resolve such dispute prior to submitting the disputed portion of such return to the Accounting Firm for binding resolution prior to filing such Tax Return. The Accounting Firm will promptly review only those items and amounts specifically set forth in the requested change(s) and resolve the dispute with respect to each requested change. The fees and expenses of the Accounting Firm will be borne by Seller and Buyer in the percentage inversely proportionate to the percentage of the total amount of the total items submitted for dispute that are resolved in such party’s favor, or determined by the Accounting Firm. The decision of the Accounting Firm will be final, conclusive and binding on the parties. Buyer shall file or cause to be

filed, within the time and in the manner required by applicable Law, such Tax Returns and pay or cause to be paid all Taxes due and owing with respect to such Tax Returns, subject to the indemnification provisions of Section 11.1. Buyer also shall prepare or cause to be prepared all Tax Returns required to be filed by or with respect to the Group Companies for all Taxable Periods beginning after the Closing Date, and file or cause to be filed, within the time and in the manner required by applicable Law, all such Tax Returns and pay or cause to be paid all Taxes due and owing with respect to such Tax Returns.

(e) In the case of Taxes that are payable with respect to a Straddle Period, the portion of any such Tax that is allocable to the portion of such Straddle Period ending on the Closing Date shall be:

(i) in the case of Taxes that are either (A) based upon or related to income or receipts or (B) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible), deemed equal to the amount which could be payable if the Taxable Period ended on the Closing Date and the Parties shall elect to do so if permitted by applicable Law; and

(ii) in the case of Taxes imposed on a periodic basis with respect to the assets of any Group Company, or otherwise measured by the level of any item, deemed to be the amount of such Taxes for the entire Straddle Period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding Taxable Period), multiplied by a fraction the numerator of which is the number of days in the Straddle Period ending on the Closing Date and the denominator of which is the number of days in the entire Straddle Period.

(f) (i) After the Closing Date, Buyer shall notify Seller in writing within fifteen (15) Business Days of receiving notice of any proposed assessment or the commencement of any Tax audit or administrative or judicial proceeding or of any demand or claim on Buyer or any Group Company, that if determined adversely to the taxpayer or after the lapse of time, could be grounds for indemnification under Section 11.1. Such notice shall contain factual information (to the extent known to Buyer) describing the asserted Tax liability in reasonable detail and shall include copies of any notice or other document received from any Tax Authority in respect of any such asserted Tax liability. The failure to give notice as provided in this Section 8.1(f) shall not relieve the Indemnitor of its obligations hereunder except to the extent it shall have been prejudiced by such failure.

(ii) In the case of a Tax audit or administrative or judicial proceeding (a “Contest”) relating to any Group Company solely with respect to a Taxable Period ending on or prior to the Closing Date, Seller shall have the sole right, at its expense, to control the conduct of such Contest; provided, that, in the event that any such Contest could result in an adjustment to Tax of any Group Company for a Taxable Period or portion thereof ending after the Closing Date, Seller (A) shall permit Buyer, at its expense, to participate in the proceeding solely with respect to an adjustment that might affect the Tax liability of Buyer or any Group Company for a Taxable Period ending after the Closing Date and (B) shall not settle or otherwise compromise such Contest without the prior written consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, except as may be required by Law, Seller shall take no position that Buyer determines will result in any material negative Tax consequence to Buyer or the Group Companies after the Closing Date without the prior written consent of Buyer (which consent shall not be reasonably withheld, conditioned, or delayed).

(iii) In the case of any other Contest relating to any Group Company, Buyer shall have the sole right, at Buyer’s expense, to control the conduct of such Contest; provided, that, in the event that any such Contest could result in an adjustment to Tax of any Group Company for a Taxable Period or portion of a Straddle Period ending on or before the Closing Date that might have an adverse effect on Seller, Buyer (A) shall permit Seller, at Seller’s expense, to participate in the proceeding solely with respect to an adjustment that might affect the Tax liability of Seller for a Taxable Period or portion of a Straddle Period ending on or before the Closing Date and (B) shall not settle or otherwise compromise such Contest without the prior written consent of Seller, which consent shall not be unreasonably withheld, conditioned or delayed.

(g) For Tax purposes, unless otherwise required by applicable Law, the Parties agree to treat all payments made under any indemnity provisions contained in this Agreement, and any payments in respect of any breaches of representations, warranties, covenants or agreements hereunder, as adjustments to the Purchase Price.

(h) Buyer and Seller agree that the Group Companies shall become members of the federal income consolidated tax group of which Buyer is the common parent on the day after the Closing Date. To the extent applicable, any state or local Income Tax Returns shall be prepared in accordance with provisions comparable to Treasury Regulations Section 1.1502-76(b) under state or local Law.

(i) Any Tax refunds that are received by Buyer or any Group Company, and any amounts credited against Tax to which Buyer or any Group Company become entitled, that relate to Taxable Periods or portions thereof ending on or before the Closing Date shall be for the account of Seller, and Buyer shall pay or cause to be paid over to Seller any such refund or the amount of any such credit within five (5) Business Days after receipt or entitlement thereto. Buyer will, and will cause the Group Companies to, execute such documents, take reasonable additional actions and otherwise reasonably cooperate as may be necessary for the Group Companies to perfect their rights in and obtain all Tax refunds and credits for which any such Person is eligible and to which Seller is entitled. None of Buyer or Seller shall, or shall permit any Group Company to, forfeit, fail to collect or otherwise minimize any Tax refund or credit to which Seller would be entitled, whether through any election to carry forward a net operating loss or otherwise.

(i) If requested by Buyer, Buyer and Seller shall timely make a joint election under Section 338(h)(10) of the Code (a “338(h)(10) Election”) with respect to the direct or indirect purchase of the common stock of any or all of the Group Companies that are treated as corporations for federal Income Tax purposes (each such entity is herein referred to as a “Corporate Group Company” and its shares of stock as “Group Company Shares”). Buyer and Seller shall, at the request of Buyer, make any analogous election with respect to state, local or foreign Taxes, to the extent that such election is separately available. Buyer and Seller shall duly execute, or cause to be executed, any form (including IRS Form 8023 and IRS Form 8883) and to the extent required, any similar forms with respect to state, local or foreign Taxes required for purposes of making such election.

(ii) Buyer shall promptly provide written notice to Seller of any audit or other investigation that may be initiated in connection with a 338(h)(10) Election or any analogous election.

(k) To the extent the sale of any of the Units is treated as a sale of assets to Buyer for federal tax purposes and for purposes of Section 8.1(j) with respect to any direct or indirect sale of Group Company Shares, prior to execution of this Agreement, Buyer shall have prepared and delivered to Seller at least ten (10) days prior to Closing, a schedule that allocates the Purchase Price among the assets of

each of the Group Companies, including without intending any limitation, the allocation to the assets of the Corporate Group Companies, or as otherwise applicable. Such schedule shall be agreed upon by Buyer and Seller and shall be set forth in Schedule 8.1 (the “Purchase Price Allocation”). Except as required pursuant to a determination (as defined in Section 1313 of the Code or any similar provision of state or local Laws), each Party agrees to report the federal, state, local and other Tax consequences of the transactions contemplated by this Agreement in a manner consistent with such treatment and Purchase Price Allocation and shall not take any position inconsistent therewith upon examination of any Tax allocation and shall not take any position inconsistent therewith upon examination of any Tax Return, in any refund claim, or in any litigation, investigation, or otherwise.

8.2. Confidentiality. The Parties hereto acknowledge and agree that all confidential information relating to Seller, the Group Companies, Buyer or their respective Affiliates and businesses, including confidential matters consisting of “know-how,” trade secrets, customer lists, details of contracts, pricing policies, operational and service methods, sales data, marketing plans or strategies, service development techniques or plans, business acquisition plans, new personnel acquisition plans, technical processes, designs and design projects and inventions (collectively, “Confidential Information”) are valuable, special and unique assets of such Person to which the Confidential Information belongs and are, and upon the Closing will be, owned exclusively by such Person. Each Party agrees to, and agrees to use its reasonable best efforts to cause its directors, officers, employees, partners, Affiliates, agents, advisors (including accountants and legal counsel) and other representatives (“Representatives”) to, treat the Confidential Information, together with any other confidential information furnished to Seller or the Group Companies or their respective Affiliates by Buyer or its Affiliates, on the one hand, or to Buyer or its Affiliates by Seller, the Group Companies or any of their respective Affiliates, on the other hand, as confidential and not to make use of such information for its own purposes or for the benefit of any other Person. To the extent the terms in this Section 8.2 conflict with the terms of the confidentiality letter agreement, dated as of September 27, 2011, between Seller and Buyer or its Affiliate (the “Confidentiality Agreement”), the terms of this Section 8.2 shall supersede the conflicting terms in the Confidentiality Agreement.

(a) Buyer agrees that it and the Group Companies shall be solely responsible for satisfying the continuation coverage requirements of Section 4980B of the Code for all individuals who are “M&A qualified beneficiaries” as such term is defined in Treasury Regulation Section 54.4980B-9. Buyer agrees that, following the Closing Date, it will not take any action which would trigger liability for Seller or any of its Affiliates under the WARN Act.

(b) As of Closing, as applicable, Seller or the Group Companies shall terminate the employees listed on Schedule 8.3(b) and, as of the Closing, Buyer will offer employment to such employees on an at-will basis and subject to Buyer’s customary employee screening and employment practices, policies and procedures. In addition, all employees of the Group Companies shall continue to be employed by the Group Companies on an at will basis as of and following the Closing. All employees listed on Schedule 8.3(b) or employed by the Group Companies as of Closing shall be referred to herein as “Acquired Employees.”

(c) During the period beginning on the Closing Date and ending no earlier than the first anniversary thereof, Buyer shall, or shall cause the Group Companies to, provide compensation and benefits to the Acquired Employees that are no less than the compensation and benefits provided to such employees immediately prior to the Closing.

(d) From and after the Closing Date, Buyer shall cause all Acquired Employees to be granted credit for any service with Seller and any Group Company earned prior to the Closing Date for purposes of benefit eligibility and vesting (but not benefit accrual). In addition, Buyer hereby agrees that Buyer shall cause all covered expenses incurred during the calendar year in which the Closing Date occurs by any Acquired Employee (or covered dependent thereof) to be taken into account for purposes of satisfying applicable deductible, coinsurance and maximum out-of-pocket provisions after the Closing Date for the remainder of such calendar year.

(e) Seller shall take all necessary or appropriate steps in order to terminate the participation of the Acquired Employees in any Benefit Plans effective as of the Closing Date and Seller shall take any and all action necessary to authorize and direct the administrators of the Benefit Plans to take such actions. Seller shall maintain and/or distribute, as appropriate, the account balances of the Acquired Employees in any Benefit Plan that is intended to be qualified under Section 401(a) of the Code (“Retirement Plan”) in accordance with the terms of such Retirement Plan, the Code and ERISA. Buyer agrees to use its commercially reasonable efforts to facilitate the rollover of the accounts held for the Acquired Employees in the Retirement Plan who voluntarily elect to make such rollovers into a retirement plan maintained by Buyer or its affiliates, as and to the extent such rollovers are permissible under applicable laws and regulations and the terms of Buyer’s plans. Seller shall amend the Retirement Plan to provide that the accrued account balances of the Acquired Employee shall fully vest at the Closing Date, unless Buyer requests a plan to plan transfer as provided in the following sentence. Notwithstanding the foregoing, if requested by Buyer on or before the Closing Date, Seller shall transfer the accrued account balances of the Acquired Employees (which shall include both vested and nonvested portion of such accounts) to a plan maintained by the Buyer as a plan-to-plan transfer pursuant to section 414(l) of the Code as soon as reasonable practicable after the Closing Date.

8.4. Access to Records after Closing. For a period of six (6) years after the Closing Date, Seller and its Affiliates and Representatives shall have reasonable access to all of the books and records of the Group Companies to the extent that such access may reasonably be required by Seller in connection with any legitimate matter relating to or affected by the operations of the Group Companies prior to the Closing Date. Such access shall be afforded by Buyer upon receipt of reasonable advance notice and during normal business hours. Seller shall be solely responsible for any costs or expenses incurred by it pursuant to this Section 8.4. If Buyer or any Group Company shall desire to dispose of any of such books and records prior to the expiration of such 6-year period, Buyer shall, prior to such disposition, give Seller a reasonable opportunity, at Seller’s expense, to segregate and remove such books and records as Seller may select.

8.5. Insurance for Pre-Closing Occurrences or Events. At the Closing Date, Buyer or one of its Affiliates will purchase on behalf of the Group Companies, a “nose” policy reasonably acceptable to Buyer from an insurer reasonably acceptable to Buyer that will provide insurance coverage for all events that occurred in the period prior to the Closing Date if such events or occurrences would give rise to a claim under the Facilities’ general and professional liability insurance policies, regardless of whether such events or occurrences are known or unknown to the Seller as of the Closing Date (the “Nose Coverage”). Such Nose Coverage shall be purchased in one or more premium payments (the “Nose Premium”) and shall include coverage deductibles and limits reasonably satisfactory to Buyer and similar to those contained in Seller’s historical professional and general liability insurance policies applicable to the Facilities, taking into account the limits in the Facilities’ historical liability policies covering the Facilities prior to the Closing. Buyer, and any of its Affiliates reasonably determined by Buyer, will be the named insured or listed as additional insureds with respect to the Nose Coverage. Given that the policies will be owned by the Group Companies’ being acquired by the Buyer in accordance with the terms of this Agreement, Buyer and its Affiliates will take responsibility for the administration of all claims that arise following the Closing Date, regardless of whether such claims relate to events that occurred prior to the Closing Date (in which case the claims will be covered by the Nose Coverage). Seller shall pay $500,000 to Buyer out of the Purchase Price delivered on the Closing Date to go toward Buyer’s payment of the Nose Premium.

8.6. Transition Services. After Closing, Seller shall provide Buyer and the Group Companies the business office services currently performed at the Seller’s corporate offices and such other transition services as may be mutually agreed to by Seller and Buyer upon the terms and conditions set forth on Schedule 8.6.

8.7. Further Assurances. Each Party will use reasonable best efforts to take all further actions and execute and deliver all further documents that are necessary to carry out the intent and purposes of this Agreement and the Buyer Ancillary Agreements and Seller Ancillary Agreements.

8.8. Covenant Not to Compete. Seller and its Affiliates hereby covenant and agree with Buyer and its Affiliates that, during the Non-Compete Period (as such term is defined below) and within the Non-Compete Area (as such term is defined below), they shall not directly or indirectly, (a) acquire, lease, manage, consult for, serve as agent or subcontractor for, finance, invest in, own any part of or exercise management control over any in-patient psychiatric facility or business that provides services that are the same or similar to the services provided by any of the Facilities (a “Competing Business”); (b) solicit for employment or employ any person who is employed by the Group Companies as of the Closing Date or any Acquired Employee (other than general media advertisements of employment opportunities), or (c) disrupt or attempt to disrupt any past, present or reasonably foreseeable future relationship, contractual or otherwise between the Facilities, on the one hand, and any physician, physician group, or other healthcare provider with whom any Group Company contracts with in connection with the Facilities or make statements to the same that disparage Buyer and its Affiliates or their respective operations in any way. The “Non-Compete Period” shall commence on the Closing Date and terminate on the third anniversary of the Closing Date. The “Non-Compete Area” shall mean the area within a fifty (50) mile radius of each Facility, including any satellite locations thereof. Ownership of less than three percent (3%) of the stock of a publicly held company shall not be deemed a breach of this covenant. Notwithstanding the foregoing, the foregoing restrictions shall not preclude Seller, Parent or any of their Affiliates from (A) acquiring, by asset or stock purchase, merger or otherwise, any entity or multiple facilities from an entity which engages in a Competing Business (the “Acquired Competing Business”), so long as (x) such acquisition is consummated not less than twelve (12) months following the Closing Date and (y) provided the gross revenue attributable to such Acquired Competing Business derived within the Non-Compete Area for the twelve (12) month period immediately preceding the date of the acquisition of such Acquired Competing Business comprises less than twenty-five percent (25%) of the gross revenue attributable to all businesses included in the Acquired Competing Business for the twelve (12) month period immediately preceding the date of the acquisition of such Acquired Competing Business or (B) being acquired by asset or stock purchase, merger or otherwise, by any unaffiliated entity which engages in a Competing Business.

8.9. Enforceability. In the event of a breach of Section 8.8, Seller and its Affiliates recognize that monetary damages shall be inadequate to compensate Buyer and its Affiliates, and Buyer and its Affiliates shall be entitled, without the posting of a bond or similar security, to an injunction restraining such breach, with the costs (including attorney’s fees) of securing such injunction to be borne by the breaching party. Nothing contained herein shall be construed as prohibiting Buyer and its Affiliates from pursuing any other remedy available for such breach or threatened breach. All parties hereby acknowledge the necessity of protection against the competition of Seller and its Affiliates and that the nature and scope of such protection has been carefully considered by the parties. The period provided and the area covered are expressly represented and agreed to be fair, reasonable and necessary. The consideration provided for herein is deemed to be sufficient and adequate to compensate the Seller and its Affiliates for agreeing to the restrictions contained in Section 8.8. If, however, any court determines that the forgoing restrictions are not reasonable, such restrictions shall be modified, rewritten or interpreted to include as much of their nature and scope as will render them enforceable.

Unless waived in accordance with this Article IX, the obligations of Buyer under this Agreement are subject to the satisfaction of each of the following conditions on or prior to the Closing Date:

(a) The representations and warranties of Seller set forth in this Agreement shall be true and correct in all respects as of the date of this Agreement and as of the Closing Date, as though made on and as of the Closing Date (other than to the extent that the representation or warranty is expressly limited by its terms to another date, in which case the representation or warranty shall have been true and correct on that date), except for inaccuracies of representations and warranties the facts, events and circumstances giving rise to which would not constitute a Group Companies Material Adverse Effect.

(b) Buyer shall have received a certificate signed by a duly authorized officer of Seller with respect to the representations and warranties contained in Article IV and Article V.

9.2. Performance of Obligations.

The waiting period under the HSR Act shall have expired or been terminated, and no Governmental Body shall have enacted, issued, promulgated, enforced or entered any Law or order, writ, judgment, injunction, decree, stipulation, determination or award (whether temporary, preliminary or permanent) that has the effect of making the Contemplated Transactions illegal or otherwise restraining or prohibiting any Contemplated Transactions. No Proceeding shall have been instituted or threatened by or before a Governmental Body which seeks to enjoin, restrain, prohibit, materially delay or obtain damages in respect of any of the Contemplated Transactions, or which would reasonably be expected to prevent or make illegal any of the Contemplated Transactions.

9.5. Governmental Approvals. All authorizations, consents, approvals, orders and waivers of or by all Governmental Bodies necessary to consummate the Contemplated Transactions, which are required to be obtained prior to the Closing by applicable Law, shall have been obtained, other than those as to which the failure to possess would not constitute a Group Companies Material Adverse Effect.

9.7. Seller Ancillary Agreements. Seller shall have executed and delivered each of the Seller Ancillary Agreements to which it is a party.

Notwithstanding the failure of any one or more of the foregoing conditions, Buyer may proceed with the Closing without satisfaction, in whole or in part, of any one or more of such conditions. To the extent that Seller delivers to Buyer a written notice specifying in reasonable detail the failure of any of such conditions or the breach by of any of the representations or warranties of Seller contained herein, and nevertheless Buyer proceeds with the Closing, Buyer shall be deemed to have waived for all purposes any rights or remedies it may have against the by reason of the failure of any such conditions or the breach of any such representations or warranties to the extent described in such notice.

(b) Seller shall have received a certificate signed by a duly authorized officer of Buyer, in such capacity, certifying to such effect.

10.2. Performance of Obligations. Buyer shall have performed, in all material respects, all agreements and covenants required to be performed by it under this Agreement at or prior to the Closing Date, and Seller shall have received a certificate signed by an authorized officer of Buyer, in such capacity, certifying to such effect.

10.3. No Restraint. The waiting period under the HSR Act shall have expired or been terminated, and no Governmental Body shall have enacted, issued, promulgated, enforced or entered any Law or order, writ, judgment, injunction, decree, stipulation, determination or award (whether temporary, preliminary or permanent) that has the effect of making the Contemplated Transactions illegal or otherwise restraining or prohibiting any Contemplated Transactions.

To the extent that at the Closing, Buyer delivers to Seller a written notice specifying in reasonable detail the failure of any of such conditions or the breach by Buyer of any of the representations or warranties of Buyer contained herein, and nevertheless Seller proceeds with the Closing, Seller shall be deemed to have waived for all purposes any rights or remedies they may have against Buyer by reason of the failure of any such conditions or the breach of any such representations or warranties to the extent described in such notice.

(a) From and after the Closing, subject to the limitations in Sections 11.1(b) and (c) and the other provisions in this Article XI, Seller (jointly and severally with Parent) agrees to indemnify, defend and hold harmless each Buyer Group Member from and against any and all Losses incurred by such Buyer Group Member in connection with or arising from:

(iv) any Taxes imposed upon or payable by any of the Group Companies for any Taxable Period, or portion thereof (including those allocable to the portion of any Straddle Period), ending on or prior to the Closing Date; provided, however, Seller shall be liable only to the extent that such Taxes are in excess of the aggregate amount, if any, reserved for such Taxes on the Closing Date Balance Sheet and shall be liable for any Taxes imposed on any Group Company or for which any Group Company may otherwise be liable as a result of transactions occurring on the Closing Date that are properly allocable (based on, among other relevant factors, factors set forth in Treas. Reg. § 1.1502-76(b)(1)(ii)(B)) to the portion of the Closing Date after the Closing; or

(b) Notwithstanding the foregoing, Seller shall only be required to indemnify a Buyer Group Member for Losses incurred by such Buyer Group Member to the extent that:

(i) under Section 11.1(a)(i) and or (ii), any particular Loss equals or exceeds Five Thousand Dollars ($5,000);

(ii) under Section 11.1(a)(i) and or (ii), the aggregate amount of Losses exceeds Five Hundred Thousand Dollars ($500,000) (the “Deductible”) (it being understood that Seller be liable for the full amount of the Losses, including the Deductible amount); provided that the Deductible shall not apply to claims (x) for breaches of Section 4.2 (Authorization, Validity and Effect of Agreement), Section 4.4 (Title to Units), Section 5.2 (Capitalization), Section 5.7 (Taxes), Section 8.1 (Tax Matters) or claims for fraud, or (y) arising under Sections 11.1(a)(iii) – (v); and

(iii) the aggregate amount required to be paid or indemnified by Seller pursuant to Section 11.1(a)(i),(ii) and/or (iii) shall not exceed the amount of $5,000,000, and shall be recoverable by the Buyer Group Member only from the Escrowed Amount unless such Escrow Amount has been released to Seller, in which case, such indemnity amount may be recovered from Seller.

Notwithstanding the foregoing, the indemnification by Seller shall continue as to any Losses of which any Buyer Group Member has validly given a Claim Notice to Seller in accordance with the requirements of Section 11.3 on or prior to the date such indemnification would otherwise terminate in accordance with this Section 11.1(c), as to which the obligation of Seller shall continue solely with respect to the specific matters in such Claim Notice until the liability of Seller shall have been determined pursuant to this Article XI, and Seller shall have reimbursed all Buyer Group Members for the full amount of such Losses that are payable with respect to such Claim Notice in accordance with this Article XI.

(a) Buyer agrees to indemnify and hold harmless Seller and each Group Company from and against any and all Losses incurred by Seller or Group Company in connection with or arising from:

(i) any breach of any warranty or the inaccuracy of any representation of Buyer contained in Article VI or in the certificate delivered by Buyer to Seller pursuant to Section 10.1 of this Agreement;

(ii) any breach by Buyer of, or failure by Buyer to perform, any of its covenants and obligations contained in this Agreement; or

(iii) any Taxes imposed upon or payable by any of the Group Companies for any Taxable Period (or portion thereof) that begins after the Closing Date or the portion of any Straddle Period after the Closing Date.

(b) The indemnification provided for in Section 11.2(a) shall terminate on the Escrow Release Date (and no claims shall be made by any Seller Group Member under Section 11.2(a) thereafter), provided that the indemnification provided for in Section 11.2(a)(i) as it relates to Section 6.2 (Authority, Validity and Effect of Agreement) shall terminate upon the expiration of the statute of limitations related thereto, and as it relates to covenants shall terminate on the earlier to occur of the expiration of the period specified in the covenant or the expiration of the applicable statute of limitations. The indemnification by Buyer shall continue as to any Losses of which any Seller Group Member has validly given a Claim Notice to Buyer in accordance with the requirements of Section 11.3 on or prior to the date such indemnification would otherwise terminate in accordance with this Section 11.2(b), as to which the obligation of Buyer shall continue solely with respect to the specific matters in such Claim Notice until the liability of Buyer shall have been determined pursuant to this Article XI, and Buyer shall have reimbursed Seller for the full amount of such Losses that are payable with respect to such Claim Notice in accordance with this Article XI.

11.3. Notice of Claims. Any Person seeking or intending to seek indemnification hereunder (the “Indemnified Party”) shall give promptly to the Party or Parties obligated to provide indemnification to such Indemnified Party (each, the “Indemnitor”) a written notice (a “Claim Notice”) describing in reasonable detail the facts giving rise to the claim for indemnification hereunder and shall include in such Claim Notice (if then known) the amount or the method of computation of the amount of such claim, and a reference to the provision of this Agreement or any other agreement, document or instrument executed hereunder or in connection herewith upon which such claim is based.

11.4. Resolution of Indemnifiable Claims. After the giving of any Claim Notice pursuant to Section 11.3, the amount of indemnification to which an Indemnified Party shall be entitled under this Article XI shall be determined: (i) by the written agreement between the Indemnified Party and the Indemnitor; (ii) by a final judgment or decree of any court of competent jurisdiction; or (iii) by any other means to which the Indemnified Party and the Indemnitor shall agree. The judgment or decree of a court shall be deemed final when the time for appeal, if any, shall have expired and no appeal shall have been taken or when all appeals taken shall have been finally determined. The Indemnified Party shall have the burden of proof in establishing the amount of Losses suffered by it. Once a Loss is payable pursuant to this Section 11.4, the Indemnitor shall satisfy its obligations by wire transfer of immediately available funds to an account designated in writing by the Indemnified Party, provided that, in the event that Seller is required to indemnify any Buyer Group Member, such payment shall first be satisfied by withdrawals of the Escrow Amount in accordance with Section 2.1 and the terms and conditions of the Escrow Agreement.

(a) Any Indemnified Party seeking or intending to seek indemnification under this Agreement in respect of, arising out of or involving any claim, action, demand or Proceeding made by any Person who is not a Party or Affiliate thereof (a “Third Party Claim”) against the Indemnified Party shall promptly give a Claim Notice to the Indemnitor(s) with respect to the Third Party Claim. Thereafter, the Indemnified Party shall promptly deliver to the Indemnitor, after the Indemnified Party’s receipt thereof, copies of all notices, pleadings, demands and documents received by the Indemnified Party or its Affiliates or Representatives relating to the Third Party Claim. The failure to give notice as provided in this Section 11.5 shall not relieve the Indemnitor of its obligations hereunder except to the extent it shall have been prejudiced by such failure.

(b) In the event of a Third Party Claim, the Indemnitor shall have the sole and absolute right, at its election (within twenty (20) Business Days following its receipt of Claim Notice from the Indemnified Party with respect to such Third Party Claim) and at its expense, to control, defend against, negotiate, settle or otherwise deal with such Third Party Claim using counsel of its choice; provided, however, that the Indemnified Party may participate in any such proceeding with counsel of its choice and at its sole expense. The Indemnitor shall not settle or otherwise compromise any such Third Party Claim without the consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed) if the settlement does not include as a term thereof the giving by the Person(s) asserting such Third Party Claim to the Indemnified Party of a release from all liability with respect to such Third Party Claim. If the Indemnitor does not so elect to undertake the defense of such Third Party Claim, the Indemnified Party shall have the right to undertake the defense against the Third Party Claim; provided, that the Indemnified Party shall not settle or otherwise compromise any such Third Party Claim without the consent of the Indemnitor (which consent shall not be unreasonably withheld, conditioned or delayed). The Parties agree to cooperate fully with each other in connection with the defense, negotiation or settlement of any such Third Party Claim.

(c) To the extent of any inconsistency between this Section 11.5 and Section 8.1(f) (relating to Tax Contests), the provisions of Section 8.1(f) shall control with respect to Tax Contests.

(a) The amount of any and all Losses under this Article XI shall be determined net of (i) any Tax benefits realized by any Indemnified Party arising from the deductibility of any such Losses and (ii) any amounts actually received by the Indemnified Party under insurance policies, indemnities, warranties or other reimbursement arrangements with respect to such Losses. Each Party hereby waives, to the extent permitted under its applicable insurance policies, any subrogation rights that its insurer may have with respect to any indemnifiable Losses and agrees, promptly following such other Party’s request, to file any applicable insurance claims and will take all reasonable necessary, proper or desirable actions (including the execution and delivery of any document reasonably requested) to accomplish the foregoing.

(b) In any case where an Indemnified Party recovers from third Persons any amount in respect of a matter with respect to which an Indemnitor has indemnified it pursuant to this Article XI, such Indemnified Party shall promptly pay over to the Indemnitor the amount so recovered (after deducting therefrom the amount of reasonable expenses incurred by the Indemnified Party in procuring such recovery), but not in excess of the sum of (i) any amount previously so paid by the Indemnitor to or on behalf of the Indemnified Party in respect of such matter and (ii) any amount expended by the Indemnitor in pursuing or defending any claim arising out of such matter.

(c) Each of the Parties agrees to take all reasonable steps to mitigate their respective Losses (including using commercially reasonable efforts to recover under applicable insurance policies or other indemnities) upon and after becoming aware of any event or condition which could reasonably be expected to give rise to any Losses that are indemnifiable hereunder.

(d) Buyer shall have no right to indemnification pursuant to this Article XI with respect to any Loss or alleged Loss if such matter was addressed in the Working Capital adjustment or Buyer received a reduction in the Purchase Price pursuant to Article II.

(e) No claims by Buyer shall be so asserted for any breach of a representation or warranty contained in Article IV or Article V of this Agreement if Buyer had actual knowledge of such breach at the time of the Closing and no Losses related thereto shall be subject to indemnification by Seller hereunder.

(f) Any indemnification payment under this Agreement shall be treated as an adjustment to the Purchase Price for Tax purposes.

11.7. Exclusive Remedy. Buyer acknowledges and agrees that, from and after the Closing, its sole and exclusive remedy against Seller with respect to any and all claims relating (directly or indirectly) to the subject matter of this Agreement or the Contemplated Transactions shall be pursuant to the indemnification provisions set forth in this Article XI.

12.1. Termination. Anything contained in this Agreement to the contrary notwithstanding, this Agreement may be terminated at any time prior to the Closing Date:

(b) by Buyer (but only so long as Buyer is not in material breach of its obligations under this Agreement) if there has been a material breach of any representation, warranty, covenant or agreement of Seller, which breach would result in the failure of one or more of the conditions to Closing set forth in Article IX, and which failure or breach is not cured within thirty (30) days after Buyer has notified Seller of such breach and Buyer’s intention to terminate this Agreement pursuant to this Section 12.1(b);

(c) by Seller (but only so long as Seller is not in material breach of any of its obligations under this Agreement) if there has been a material breach of any representation, warranty, covenant or agreement of Buyer, which breach would result in the failure of one or more of the conditions to Closing set forth in Article X, and which failure or breach is not cured within thirty (30) days after Seller has notified Buyer of such breach and Seller’s intention to terminate this Agreement pursuant to this Section 12.1(c);

(d) by either Seller or Buyer in the event any Governmental Body shall have enacted, issued, promulgated, enforced or entered any Law or order, writ, judgment, injunction, decree, stipulation, determination or award that has the effect of making the transactions Contemplated Transactions illegal or otherwise restraining or prohibiting any Contemplated Transaction; or

(e) by either Seller or Buyer if the Closing shall not have occurred on or before April 1, 2012; provided, however, that (i) if the sole outstanding condition to Closing is the receipt of approval from the State of Oklahoma for the Certificate of Need of HRH, then the April 1, 2012 date set forth in this subsection (e) shall automatically be extended to May 1, 2012, and (ii) no termination may be made under this Section 12.1(e) by a Party if the failure to close on or prior to such date shall be caused by the action or inaction of such Party.

12.3. Effect of Termination.

13.1. No Public Announcement. None of the Parties or their Affiliates will issue any press release or make any public announcement with respect to the Contemplated Transactions without the prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed) of Buyer (with respect to disclosures by Seller) or Seller (with respect to disclosures by Buyer), except to the extent that the disclosing Party determines in good faith that it is so obligated by applicable Law, in which case such disclosing Party shall give notice to Buyer or Seller (as applicable) in advance of such Party’s intent to make such disclosure, announcement or issue such press release and the applicable Parties hereto or their Affiliates shall use reasonable efforts to cause a mutually agreeable release or disclosure or announcement to be issued; provided, however, that the foregoing shall not preclude communications or disclosures necessary to implement the provisions of this Agreement.

13.2. Notices. All notices or other communications required or permitted hereunder shall be in writing and shall be delivered personally, by facsimile, by reputable overnight courier (costs prepaid), or by U.S. registered or certified mail (return receipt requested and postage prepaid), and shall be deemed given or made when (i) delivered personally, (ii) the Business Day sent (or next Business Day if not sent on a Business Day or not sent during normal business hours of the recipient) if sent by facsimile with receipt confirmation, (iii) one (1) Business Day after delivery to the overnight courier for next business day delivery, and (iv) three (3) Business Days after being sent by registered or certified mail, at the following address:

The failure of any Party hereto to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of any Party thereafter to enforce each and every such provision.

representation or warranty contained in this Agreement nor the inclusion of any specific item in any section or paragraph of the Schedules is intended to imply that such amount, or higher or lower amounts, or the item so included or other items, are or are not material, or are or are not in the ordinary course of business, and no Party shall use the fact of the setting forth of any such amount or the inclusion of any such item in any dispute or controversy between the Parties as to whether any obligation, item or matter not described herein or included in any section or paragraph of the Schedules is or is not material for purposes of this Agreement, or is or is not in the ordinary course of business.

(c) EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE CONTEMPLATED TRANSACTIONS.

(a) The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, may occur in the event that the Parties do not perform the provisions of this Agreement (including failing to take such actions as are required of it hereunder to consummate this Agreement) in accordance with its specified terms or otherwise breach such provisions. The Parties acknowledge and agree that, prior to the valid termination of this Agreement pursuant to Article XII, the Parties shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which the Parties are entitled at law or in equity.
