Section 1.2 Closing Effective Time. The consummation of the Merger (the “Closing”) will take place on the date that is three (3) Business Days after the satisfaction or waiver of the conditions set forth in Article V hereof (other than those conditions that by their nature are to be satisfied at the

Closing), or at such other time as the parties to this Agreement agree (the actual date on which the Closing takes place, the “Closing Date”). The Closing will take place at the offices of Bass, Berry & Sims PLC, 150 Third Avenue South, Suite 2800, Nashville, Tennessee 37201, or at such other location as the parties to this Agreement agree. In connection with the Closing, the Company will cause the Merger to be made effective by filing a Certificate of Merger, substantially in the form attached hereto as Exhibit D, with the Secretary of State of the State of Delaware in accordance with the relevant provisions of the DGCL (the time of such filing or such later time which Parent and the Company will have agreed upon and designated in such filing in accordance with applicable Legal Requirements being the “Effective Time”).

Section 1.3 Effect of the Merger. At the Effective Time, the effect of the Merger will be as provided in this Agreement, the Certificate of Merger filed pursuant to Section 1.2 and the applicable provisions of the DGCL.

Section 1.4 Certificate of Incorporation; Bylaws. Unless otherwise agreed to by Parent and the Company prior to the Closing, at the Effective Time:

(a) the certificate of incorporation of the Company will be amended as set forth in the Certificate of Merger; and

Section 1.5 Directors and Officers. At the Effective Time, the directors and officers of Merger Sub immediately prior to the Effective Time will be the directors and officers of the Surviving Corporation, to serve until their respective successors are duly elected or appointed and qualified.

Section 1.6 Effect on Capital Stock and Company Stock Options. At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or the holders of any of the following securities:

(a) Effect on Company Capital Stock and Company Stock Options.

(i) Series A Convertible Preferred Stock. Each share of Company Series A Convertible Preferred Stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive the Per Series A Preferred Share Consideration;

(ii) Series C Convertible Preferred Stock. Each share of Company Series C Convertible Preferred Stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive the Per Series C Preferred Share Consideration;

(iii) Series D Convertible Preferred Stock. Each share of Company Series D Convertible Preferred Stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive the Per Series D Preferred Share Consideration;

(v) Closing In-The-Money Options. Each Closing In-The-Money Option that is issued and outstanding immediately prior to the Effective Time will be cancelled pursuant to an Option Cancellation Agreement and converted into the right to receive the Per In-The-Money Option Consideration;

(vi) Post-Closing In-The-Money Options. Each Post-Closing In-The-Money Option that is issued and outstanding immediately prior to the Effective Time will be cancelled pursuant to an Option Cancellation Agreement and converted into the right to receive the Per In-The-Money Option Consideration (as, if and when such amounts are required to be paid to the Post-Closing In-The-Money Options in accordance with this Agreement); and

(vii) Out-Of-The-Money Options. Each Out-Of-The-Money Option that is issued and outstanding immediately prior to the Effective Time will be cancelled pursuant to an Option Cancellation Agreement and will not be entitled to receive any Merger Consideration.

(b) Effect on Merger Sub Stock. Each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time will be converted into one share of common stock of the Surviving Corporation.

Section 1.7 Surrender of Certificates.

(a) No Further Rights as Company Stockholders. At the Effective Time, all shares of Company Capital Stock outstanding immediately prior to the Effective Time (other than Dissenting Shares) will automatically be cancelled and retired and will cease to exist, and no holder of record of a certificate that immediately prior to the Effective Time represented outstanding shares of Company Capital Stock (a “Certificate”) will have any rights as a stockholder of the Company, other than rights to receive the Merger Consideration in accordance with the terms of this Agreement.

(b) Exchange Procedures.

(i) Company Capital Stock. Upon surrender of a Certificate for cancellation to Parent, together with a letter of transmittal in the form attached to this Agreement as Exhibit A (the “Letter of Transmittal”), duly completed and validly executed in accordance with the instructions to the Letter of Transmittal, (A) the holder of such Certificate will be entitled to receive in exchange therefor cash equal to the amounts required to be paid to such holder of such Certificate upon surrender thereof in accordance with Section 1.6(a) (to the extent applicable) (as, if and when such amounts are required to be paid to such Persons in accordance with the terms of this Agreement and the Escrow Agreement) and (B) the Certificate so surrendered will be canceled. Parent will, subject to the condition set forth in the immediately preceding sentence, cause the payment described in the preceding sentence to be made to the holder of such Certificate by check or wire transfer (as indicated in the Letter of Transmittal) of immediately available funds to the account designated by such holder in the Letter of Transmittal delivered with such Certificate. Until so surrendered, each outstanding Certificate that prior to the Effective Time represented shares of Company Capital Stock (other than Dissenting Shares) will be deemed from and after the Effective Time, for all purposes, to evidence the right to receive the applicable amounts referred to in this Section 1.7(b)(i) for each of such shares (subject to the provisions of this Agreement, including the provisions relating to the Escrow Amount and the Reserve Amount).

(ii) In-The-Money Options. Upon delivery to the Parent of an executed Option Cancellation Agreement, duly completed and validly executed in accordance with the instructions

to the Option Cancellation Agreement, the holder of an In-The-Money Option shall be entitled to receive cash equal to the amounts required to be paid to such holder in respect of such surrendered In-The-Money Options in accordance with Section 1.6(a) (as, if and when such amounts are required to be paid to such Persons in accordance with the terms of this Agreement and the Escrow Agreement). Parent will, subject to the condition set forth in the immediately preceding sentence, cause the payment described in the preceding sentence to be made to such Optionholder by check or wire transfer (as indicated in the Option Cancellation Agreement) of immediately available funds to the account designated by such holder in the Option Cancellation Agreement, subject to the tax withholding requirements described in Section 1.9.

(c) Transfers of Ownership. At the Effective Time, the stock transfer books of the Company will be closed, and there will thereafter be no further issuances of or registration of transfers of shares of Company Capital Stock on the records of the Company.

(d) Escrow Agent. At or prior to the Closing, Parent and Stockholders’ Representative will enter into the Escrow Agreement in substantially the form attached hereto as Exhibit B with Regions Bank (“Escrow Agent”), which will provide that Parent will deliver on the Closing Date to the Escrow Agent cash in the amount equal to the Escrow Amount.

Section 1.8 Lost, Stolen or Destroyed Certificates. In the event any Certificate will have been lost, stolen or destroyed, Parent will pay to the record holder of such Certificate the consideration into which the shares of Company Capital Stock formerly represented by such Certificate have been converted pursuant to Section 1.6, upon the making of an affidavit of that fact by such record holder and the delivery by such record holder of an agreement to indemnify (without any bonding requirement) Parent and the Surviving Corporation against any claim that may be made with respect to such Certificate.

Section 1.9 Withholding Rights. Parent and Surviving Corporation, as applicable, shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any former stockholder or former holder of an Unexercised Option such amounts, if any, as Parent or Surviving Corporation is required to deduct and withhold with respect to the payment of such Merger Consideration under the Internal Revenue Code of 1986, as amended (the “Code”) and the rules and regulations promulgated thereunder, or under any provision of any other Legal Requirement. For administrative convenience, Parent and Surviving Corporation may tender payment with respect to any Unexercised Option to the Company’s payroll provider to be paid to the applicable holder net of any applicable withholding. To the extent that amounts are withheld from the Merger Consideration otherwise payable pursuant to this Agreement to any former stockholder or former holder of an Unexercised Option as provided in this Section 1.9 and are properly paid over to the appropriate taxing authority, such withheld amounts will be treated for all purposes of this Agreement as having been paid to such Former Stakeholder.

Section 1.10 Appraisal Rights.

(a) Prior to the Closing, the Company shall take all steps necessary to comply with Section 262 of the DGCL. All notices delivered to the stockholders of the Company relating to Section 262 of the DGCL shall be subject to the prior review and approval of Parent, which approval shall not be unreasonably withheld. Notwithstanding anything to the contrary contained in this Agreement, any share of Company Capital Stock that, as of the Effective Time, is held by a holder who has, as of the Effective Time, preserved appraisal rights under Section 262 of the DGCL with respect to such share (“Dissenting Shares”), will not be converted into or represent the right to receive Merger Consideration, and the holder of such share will be entitled only to such rights as may be granted to such holder pursuant to Section 262

of the DGCL; provided, however, that if such appraisal rights will not be perfected or the holder of such share will otherwise lose such holder’s appraisal rights with respect to such share, then, as of the later of the Effective Time or the time of the failure to perfect such status or the loss of such rights, such share will cease to constitute Dissenting Shares and will automatically be converted into and will represent only the right to receive (upon the surrender of the Certificate or Certificates representing such shares or the completion of the process described in Section 1.7) the applicable Merger Consideration, without interest.

(b) The Company will give Parent (i) prompt notice of any written demand received by the Company prior to the Effective Time to require the Company to purchase shares of Company Capital Stock pursuant to Section 262 of the DGCL and of any other demand, notice or instrument delivered to the Company prior to the Effective Time pursuant to the DGCL, and (ii) the opportunity to participate in all negotiations and proceedings with respect to any such demand, notice or instrument. The Company will not make any payment or settlement offer prior to the Effective Time with respect to any such demand unless Parent will have consented in writing to such payment or settlement offer, which consent will not be unreasonably withheld, conditioned or delayed. Each dissenting stockholder who, pursuant to Section 262 of the DGCL, becomes entitled to payment of the fair value of the dissenting shares will receive payment therefor (but only after the value therefor has been agreed upon or finally determined pursuant to such provisions).

Section 1.11 Taking of Further Action. If at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of Company and Merger Sub, from and after the Effective Time Parent and the Surviving Corporation are fully authorized in their respective names to take, and will take, all such lawful and necessary or desirable action, so long as such action is not inconsistent with this Agreement.

Section 1.12 Estimated Closing Statement; Allocation Schedule. No less than five (5) Business Days prior to the Closing Date, the Company shall deliver to Parent and Merger Sub:

(a) a statement (the “Estimated Closing Statement”) setting forth the Company’s good faith estimate (each, without duplication) of (A) the Working Capital as of the close of business on the day immediately preceding the Closing Date (the “Estimated Working Capital”), (B) the Indebtedness as of the close of business on the day immediately preceding the Closing Date (the “Estimated Indebtedness”), (C) the Cash as of the close of business on the day immediately preceding the Closing Date (the “Estimated Cash”), and (D) all unpaid Transaction Expenses as of the Closing (the “Estimated Transaction Expenses”); and

(b) a schedule in substantially the form attached hereto as Annex A (which is attached hereto solely for illustrative purposes as an example) (the “Allocation Schedule”), which shall be prepared in good faith by the Stockholders’ Representative using the procedure and methodology set forth on Annex A, which shall set forth an updated, detailed calculation of all amounts payable at Closing pursuant to Section 1.17 (subject to and in accordance with the terms of this Agreement), including:

(i) the Residual Merger Consideration Amount; and

(ii) the number of shares of Company Common Stock and Company Preferred Stock and the number of shares of Company Common Stock issuable upon exercise of In-The-Money Options, each on a fully-adjusted and fully-diluted basis after accounting for any applicable stock splits, anti-dilution provisions and any other similar provisions or events, along with the name of each Former Stakeholder and each

Former Stakeholder’s pro rata amount payable hereunder with respect to such Former Stakeholder.

The Company, the Stockholders’ Representative (on behalf of the Former Stakeholders), Parent and Merger Sub acknowledge and agree that each of Parent, Merger Sub and the Company can rely on the Allocation Schedule as setting forth a true, complete and accurate listing of all amounts due to be paid by Parent, Merger Sub and the Company to the Former Stakeholders pursuant to this Agreement. Neither Parent nor the Surviving Corporation shall have any liability with respect to the allocation of proceeds among the Former Stakeholders resulting from any payments made to such Former Stakeholders pursuant to the Allocation Schedule, and the Former Stakeholders hereby release Parent and the Surviving Corporation from any Loss relating to the allocation of the Merger Consideration pursuant to the Allocation Schedule. Following the Closing, the Stockholders’ Representative shall have the right to update the Allocation Schedule prior to the distribution of any Post-Closing Merger Consideration Amounts in order to accurately reflect how such Post-Closing Merger Consideration Amounts should be distributed to the Former Stakeholders pursuant to the terms of this Agreement, and each Former Stakeholder, by execution of a Letter of Transmittal (or Option Cancellation Agreement), thereby agrees to cooperate with the Stockholders’ Representative, Parent, the Surviving Corporation and the other Former Stakeholders in order to ensure that each Former Stakeholder receives its respective portion of any Post-Closing Merger Consideration Amounts which it may be entitled to receive pursuant to the terms of this Agreement. Each Former Stakeholder agrees that the Stockholders’ Representative shall have reasonable discretion in interpreting the Agreement and, absent manifest error or willful misconduct, such determination shall be binding on all Former Stakeholders.

Section 1.13 Final Closing Statement Determination.

(a) As promptly as practicable, but no later than sixty (60) days after the Closing, Parent shall deliver to the Stockholders’ Representative, on behalf of the Former Stakeholders, a statement (the “Proposed Closing Statement”) setting forth a good faith determination (each without duplication) of the Working Capital, Cash and Indebtedness as of the close of business on the day immediately preceding the Closing Date and unpaid Transaction Expenses as of the Closing. Parent shall and shall cause the Surviving Corporation and its Subsidiaries and its and their respective employees and agents to provide reasonable assistance to the Stockholders’ Representative and its agents in their review of the Proposed Closing Statement and shall provide the Stockholders’ Representative and its agents reasonable access during normal business hours to the personnel, properties, books and records of the Surviving Corporation and its Subsidiaries for such purpose.

(b) The Estimated Closing Statement, the Proposed Closing Statement and the Final Closing Statement shall be prepared with the same accounting principles, policies, methodologies or procedures used in preparing the Reference Balance Sheet and Annex B attached hereto (the “Accounting Policies”).

(c) In the event the Stockholders’ Representative disputes the correctness of the Proposed Closing Statement, the Stockholders’ Representative shall notify Parent in writing of its objections within sixty (60) days after receipt of the Proposed Closing Statement and shall set forth, in writing and in reasonable detail, the reasons for the Stockholders’ Representative’s objections (a “Notice of Disagreement”).

(d) During the thirty (30) days immediately following the delivery of any Notice of Disagreement, Parent and the Stockholders’ Representative shall seek in good faith to resolve any

differences that they may have with respect to any matter specified in such Notice of Disagreement. During such period, Parent and the Stockholders’ Representative and their respective agents shall each have reasonable access to the other party’s working papers, trial balances and similar materials prepared in connection with the other party’s preparation of the Proposed Closing Statement and the Notice of Disagreement, as the case may be. The matters set forth in any written resolution executed by Parent and the Stockholders’ Representative shall be final and binding on the parties on the date of such written resolution.

(e) If, at the end of such thirty (30) day period specified in Section 1.13(d), Parent and the Stockholders’ Representative have not been able to resolve, in writing, all differences that they may have with respect to any matter specified in such Notice of Disagreement, Parent and the Stockholders’ Representative shall submit to a mutually agreeable independent accounting firm (the “Accounting Firm”) for review and resolution of solely those matters specified in such Notice of Disagreement that remain in dispute (and as to no other matter), and the Accounting Firm shall reach a final, binding resolution of solely those matters specified in such Notice of Disagreement that remain in dispute, which final resolution shall not be subject to collateral attack for any reason (other than fraud or manifest error) and shall be (i) in writing and signed by the Accounting Firm, (ii) within the range of the amount of each item in dispute contested by the Stockholders’ Representative and Parent on an item by item basis, (iii) furnished to Parent and the Stockholders’ Representative as soon as practicable after the items in dispute have been referred to the Accounting Firm, which shall not be more than sixty (60) days after such referral, (iv) based solely on written materials submitted by Parent and the Stockholders’ Representative (i.e., not an independent review), (v) made in accordance with this Agreement, including the definitions of Working Capital, Cash and Indebtedness and the Accounting Policies and (vi) conclusive and binding upon the parties on the date of delivery of such written resolution. If Parent and the Stockholders’ Representative cannot agree upon the Accounting Firm, Parent and the Stockholders’ Representative shall each select one accounting firm and those accounting firms shall select the Accounting Firm. The Surviving Corporation and the Stockholders’ Representative agree to execute, if requested by the Accounting Firm, an engagement letter in customary form. The Surviving Corporation, Parent and the Stockholders’ Representative agree to cooperate fully with the Accounting Firm and promptly provide all documents and information requested by the Accounting Firm so as to enable it to make such determination as quickly and as accurately as practicable. The procedure outlined in this Section 1.13(e) is referred to as the “Dispute Resolution Procedure”.

(f) The Proposed Closing Statement shall become the “Final Closing Statement” (i) on the earlier of (x) the sixty-first (61^st) day following the delivery of the Proposed Closing Statement if a Notice of Disagreement has not been delivered to Parent by the Stockholders’ Representative and (y) the date upon which the Stockholders’ Representative acknowledges in writing that it has no objections to the Proposed Closing Statement, (ii) with such changes as are necessary to reflect matters resolved pursuant to any written resolution executed pursuant to Section 1.13(d), on the date such resolution is executed, if all outstanding matters are resolved through such resolution and (iii) with such changes as are necessary to reflect matters resolved pursuant to Section 1.13(d) and the Accounting Firm’s resolution of matters in dispute, on the date the Accounting Firm delivers its final, binding resolution pursuant to Section 1.13(e). The date on which the Proposed Closing Statement shall become the Final Closing Statement pursuant to the immediately foregoing sentence is referred to as the “Final Determination Date”.

(g) Parent and the Stockholders’ Representative shall each pay their own costs and expenses incurred in connection with such Dispute Resolution Procedure; provided, that the Parent and the Stockholders’ Representative shall each pay one-half (1/2) of the fees and expenses of the Accounting Firm.

Section 1.14 Closing Adjustment.

(a) Working Capital. If the Working Capital set forth in the Final Closing Statement (the “Actual Working Capital”) is greater than the Estimated Working Capital (a “Working Capital Surplus”), (i) Parent shall pay an amount equal to the product of (A) such Working Capital Surplus and (B) 0.594 to the Former Stakeholders in accordance with instructions from the Stockholders’ Representative within five (5) Business Days of the Final Determination Date by wire transfer of immediately available United States funds, and (ii) Parent and the Stockholders’ Representative shall instruct the Escrow Agent to pay the working capital portion of the Escrow Fund to the Former Stakeholders in accordance with instructions from the Stockholders’ Representative and the Escrow Agreement.

(b) Indebtedness. If the Indebtedness set forth in the Final Closing Statement (the “Actual Indebtedness”) is less than the Estimated Indebtedness, Parent shall pay to the Former Stakeholders in accordance with instructions from the Stockholders’ Representative the amount of such difference, within five (5) Business Days of the Final Determination Date, by wire transfer of immediately available United States funds. If the Estimated Indebtedness is less than the Actual Indebtedness, Parent and the Stockholders’ Representative shall promptly instruct the Escrow Agent to pay from the Escrow Fund the amount of such difference to the Parent by wire transfer of immediately available United States funds within five (5) Business Days of the Final Determination Date.

Parent by wire transfer of immediately available United States funds within five (5) Business Days of the Final Determination Date.

(e) Set-off.

(e) Earnout Consideration Procedures.

(i) On or before the date that is 60 days following the date that is 12 months from the Closing Date, for purposes of determining Earnout Payment I, Parent will prepare and deliver to the Stockholders’ Representative a reasonably detailed written statement (the “Earnout Payment I Statement”) setting forth Parent’s good faith calculation of Center-level EBITDA for Earnout Period I. Such calculation of Center-level EBITDA for Earnout Period I will be derived from the unaudited financial statements of Parent and its Subsidiaries for Earnout Period I (the “Earnout Payment I Financial Statements”). The amount of Earnout Payment I as calculated in the Earnout Payment I Statement shall be distributed from the Escrow Fund to the Stockholders’ Representative for the benefit of the Former Stakeholders at the time such Earnout Payment I Statement is delivered, subject to the terms of the Escrow Agreement and the Parent Indemnified Persons’ rights to indemnification pursuant to Article VIII. An amount equal to the sum of (A) the Earnout Potential minus (B) the amount of Earnout Payment I (without reduction for any pending claims) shall be distributed from the Escrow Fund to Parent at the time such Earnout Payment I Statement is delivered, subject to the terms of the Escrow Agreement.

(ii) On or before the date that is 60 days following December 31, 2012, for purposes of determining the Earnout Payment II, Parent will prepare and deliver to the Stockholders’ Representative a reasonably detailed written statement (the “Earnout Payment II Statement” and, together with the Earnout Payment I Statement, the “Earnout Statements”) setting forth Parent’s good faith calculation of Center-level EBITDA for Earnout Period II. Such calculation of Center-level EBITDA for Earnout Period II will be derived from the audited consolidated financial statements of the Parent and its Subsidiaries as of December 31, 2012. The amount of Earnout Payment II as calculated on the Earnout Payment II Statement shall be distributed from the Escrow Fund to the Stockholders’ Representative for the benefit of the Former Stakeholders at the time such statement is delivered, subject to the terms of the Escrow Agreement and the Parent Indemnified Persons’ rights to indemnification pursuant to Article VIII. An amount equal to the sum of (A) the remaining Escrow Amount at the end of Earnout Period II minus (B) the amount of Earnout Payment II (without reduction for any pending claims) shall be distributed from the Escrow Fund to Parent at the time such Earnout Payment II Statement is delivered, subject to the terms of the Escrow Agreement.

(iii) The calculations set forth on the Earnout Statements shall be prepared using the Earnout Accounting Mechanics, consistently applied throughout the relevant measurement periods. In preparing the Earnout Statements, the parties shall disregard any changes in (i) post-merger related costs associated with integration, rebranding or similar expenses, (ii) regional billing office billing methodology, (iii) Parent overhead charges and intercompany charges payable to the Parent or any of its Subsidiaries, (iv) purchase accounting, (v) non-cash charges, and (vi) other charges associated with a change in accounting pronouncements or methodologies, made by Parent after Closing that negatively impact expenses at any surgery center operated by the Subsidiaries of the Surviving Corporation by more than $5,000 in the aggregate during an earnout period.

(iv) Within 45 days after delivery of the applicable Earnout Statement, the Stockholders’ Representative may deliver written notice (the “Objection Notice”) to Parent of any objections that the Stockholders’ Representative may have to the applicable Earnout Statement. Such Objection Notice will set forth in reasonable detail the nature and basis of such objection together with

the amount(s) in dispute. The failure of the Stockholders’ Representative to deliver such Objection Notice within the prescribed time period will constitute the Stockholders’ Representative’s acceptance of the applicable Earnout Statement as determined by Parent. Upon receipt of the applicable Earnout Statement, the Stockholders’ Representative and its representatives will be given reasonable access, during normal business hours, to all of the Surviving Corporation’s books and records (including working papers, schedules and calculations) reasonably relating to the preparation of the applicable Earnout Statement. The Stockholders’ Representative and its representatives may make inquiries of Parent and its respective representatives and employees regarding questions concerning or disagreements with the applicable Earnout Statement arising in the course of their review thereof, and Parent will use reasonable efforts to cooperate in good faith with and respond to such inquiries.

(v) Upon receipt of the Objection Notice within such 45-day period, Parent and the Stockholders’ Representative will attempt in good faith to resolve any dispute regarding the applicable Earnout Statement. If Parent and the Stockholders’ Representative are unable to resolve any disagreement with respect to the applicable Earnout Statement within 15 days following Parent’s receipt of the Objection Notice, then such dispute will be submitted to a mutually agreeable independent accounting firm (the “Arbitrating Accountant”). If Parent and the Stockholders’ Representative cannot agree upon the Arbitrating Accountant, Parent and the Stockholders’ Representative shall each select one accounting firm and those accounting firms shall select the Arbitrating Accountant. The Arbitrating Accountant will be instructed to send to Parent and the Stockholders’ Representative, within 15 days of the date on which such dispute is referred to such Arbitrating Accountant, its determination of only the specific matters remaining in dispute which calculation will be based solely on written presentations made by the parties and in accordance with this Agreement (including the related definitions), and not on the basis of an independent review, and with respect to each individual item will be at or between the determinations prepared by the Stockholders’ Representative and Parent and will be final and binding on all parties. The parties shall promptly comply with all reasonable requests by the Arbitrating Accountants for information, book, records and similar items. The fees and expenses of the Arbitrating Accountant will be allocated between Parent, on the one hand, and the Stockholders’ Representative, on the other hand, so that (i) the amount of fees and expenses paid by the Stockholders’ Representative will be equal to the product of (A) and (B), where (A) is the aggregate amount of such fees and expenses, and where (B) is a fraction, the numerator of which is the amount in dispute that is ultimately unsuccessfully disputed by the Stockholders’ Representative (as finally determined by the Arbitrating Accountant), and the denominator of which is the total value in dispute, and (ii) the amount of fees and expenses payable by Parent will be the balance of such fees and expenses.

(vi) The additional Earnout Consideration in excess of amounts reflected on the Earnout Statements and paid to the Former Stakeholders pursuant to Sections 1.15(e)(i) and (e)(ii), if any, will be paid to the Former Stakeholders within five (5) days after the final determination of the applicable additional earnout payment pursuant to this Section 1.15(e).

(vii) Parent agrees that from and after the Closing Date and until and including the expiration of Earnout Period II, Parent shall ensure that the Surviving Corporation and its Subsidiaries have adequate capital as set forth in the Company’s 2011 capital budget previously provided to Parent and working capital as otherwise needed to conduct its business in the ordinary course as currently conducted. The Former Stakeholders acknowledge that following the Closing, Parent and the Surviving Corporation shall conduct the business of each Company Subsidiary in the ordinary course and may take actions that they, in good faith, believe to be in the best interest of such Company Subsidiary, even if those actions could have a negative impact on the amount of Earnout Consideration received by the Former Stakeholders as contemplated by this Section 1.15; provided, however, that Parent and the

Surviving Corporation shall not take any action with the intent or for the purpose of reducing the Earnout Consideration to be paid to the Former Stakeholders pursuant to this Section 1.15. Parent agrees that during Earnout Period I and Earnout Period II it will not cause the Surviving Corporation to consolidate two or more Subsidiaries without the prior written consent of the Stockholders’ Representative (which shall not be unreasonably withheld, conditioned or delayed), and Parent and the Stockholders’ Representative agree that, in connection with any request for such consent, Parent and the Stockholders’ Representative shall negotiate, in good faith, with respect to an appropriate adjustment, if any, to the Minimum Center-level EBITDA and Target Center-level EBITDA to reflect the proposed consolidation. In the event Parent or the Surviving Corporation sells or otherwise transfers all or a portion of its ownership interest in one or more of the Company’s Subsidiaries during Earnout Period I or Earnout Period II such that the Surviving Corporation does not hold a direct or indirect majority ownership interest in a Company Subsidiary, such Subsidiary’s portion of the Target Center-level EBITDA set forth on Annex C shall be deemed to have been earned for purposes determining Center-level EBITDA in Earnout Period I or Earnout Period II (as applicable). In the event Parent or the Surviving Corporation sells or otherwise transfers part, but less than all, of its ownership interest in one or more of the Company’s Subsidiaries during Earnout Period I or Earnout Period II but retains a direct or indirect majority ownership interest in such Company Subsidiary, such Subsidiary’s portion of the Target Center-level EBITDA set forth on Annex C shall be appropriately adjusted to reflect the change in the Surviving Corporation’s direct or indirect ownership interest for purposes determining Center-level EBITDA in Earn-Out Period I or Earn-Out Period II (as applicable) and the Minimum Center-level EBITDA will be reduced proportionately. The parties agree that Parent and its Affiliates do not owe any fiduciary duty to the Former Stakeholders, but instead the parties intend the provisions of this Agreement (including this Section 1.15) to govern their contractual relationship.

(f) Preliminary Statements. Within thirty (30) calendar days following the end of each full calendar month following the Closing through the month ending December 31, 2012, the Surviving Corporation shall prepare and deliver to the Stockholders’ Representative (x) the unaudited consolidated financial statements of the Surviving Corporation and its Subsidiaries as of the portion of the applicable earnout period then ended (the “Preliminary Financial Statements”), and (y) a preliminary statement (the “Preliminary Earnout Statement”) setting forth the Surviving Corporation’s good faith calculation of Center-level EBITDA for each applicable earnout period (i) for such applicable fiscal month then ended and (ii) for the period beginning on the Closing Date to the applicable fiscal month then ended (until the end of Earnout Period I) and (iii) for the period beginning January 1, 2012 to the applicable fiscal month then ended, in each case, in accordance with the Earnout Accounting Mechanics. Within 15 days of receipt of the Preliminary Financial Statements and the Preliminary Earnout Statement, the Stockholders’ Representative shall review such statements and notify Parent in writing of any good faith material disagreement the Stockholders’ Representative may have with respect to the content of such statements. Each of the Surviving Corporation and Parent shall make itself and, as applicable, its employees available during normal business hours, upon the reasonable request of the Stockholders’ Representative, to discuss the Preliminary Financial Statements and the Preliminary Earnout Statements as well as any notices of disagreement provided under this Section 1.15(f). Failure by the Stockholders’ Representative to provide a notice of disagreement shall in no event prohibit the Stockholders’ Representative from providing an Objection Notice pursuant to Section 1.15(e)(iv). The Preliminary Financial Statements and the Preliminary Earnout Statements shall be prepared in good faith based upon information known to the Surviving Corporation at the time of such preparation.

Section 1.16 Closing Deliveries. In addition to any other documents to be delivered under other provisions of this Agreement, at the Closing:

(a) The Company shall deliver, or cause to be delivered, to Parent:

If it is ever held by a court of competent jurisdiction that the restriction placed on Parent by this Section 4.11 is too onerous and is not necessary for the protection of the Company and/or such Subsidiaries, Parent agrees that any such court of competent jurisdiction may impose lesser restrictions which such court may consider to be necessary or appropriate to properly protect the Company and/or such Subsidiaries. For the avoidance of doubt, “solicit” for employment shall not be deemed to include general solicitations of employment not specifically directed toward Key Employees or any inquiry made independently by any Key Employee.

ADDITIONAL AGREEMENTS

Section 6.1 Publicity. No public announcement or similar publicity with respect to this Agreement or the transactions contemplated hereby will be issued by any party or any party’s respective Affiliates, officers, directors, stockholders or representatives without the prior written consent of Parent

and the Stockholders’ Representative; provided, however, that nothing contained herein will, subject to Section 6.2 below, limit the parties from making any announcements, statements or acknowledgments to the limited extent that such party is required by applicable Legal Requirements to make, issue or release.

The Company will consult with Parent concerning the means by which the Company’s and its Subsidiaries’ employees, Physician Partners, lessors, creditors and others having business relations with the Company and its Subsidiaries will be informed of the transactions contemplated hereby, and Parent shall have the right to approve (such approval not to be unreasonably conditioned, withheld or delayed), and shall have the right to be present for, any such communications.

Section 6.2 Confidentiality.

(a) Following the Closing, to the extent Parent determines to transition the employees of the Company and its Subsidiaries to Parent’s Employee Benefit Plans, the employees of the Company that continue their employment with Parent shall be eligible to participate in the applicable employee benefit plans in which similarly situated employees of Parent participate, but not with more significant benefits or levels as similarly situated employees of Parent (and not to the extent of any duplication of benefits with any Employee Benefit Plan of the Company continued after the Closing); provided, however, that the foregoing shall in no event obligate the Company to offer (or maintain) such or any other benefits (including existing benefits) to, or continue the employment of, such persons for any period following the Closing Date. With respect to any employee benefit plan as may be maintained for the Company’s employees from time to time following the Closing Date by the Parent, service by such employees performed for the Company prior to the Closing (to the extent recognized for such purposes by the Company prior to the Closing and to the extent permitted by the applicable insurer or plan vendor) shall be treated as service with the Parent, as the case may be, for purposes of determining eligibility to participate, vesting and, solely for purposes of any vacation, personal or sick days or severance program, benefit accruals. Such service also shall apply for purposes of satisfying any waiting periods, evidence of insurability requirements or the application of any preexisting condition limitations, in each case to the

extent such requirements were satisfied under analogous Employee Benefit Plans prior to the Closing and to the extent permitted by the applicable insurer or plan vendor.

(b) If requested by Parent not less than five (5) Business Days prior to Closing, the Company will adopt, or will cause to be adopted, all necessary corporate resolutions to terminate the 401(k) Plan sponsored or maintained by the Company, effective as of no later than one day prior to Closing (but such termination may be contingent upon the Closing). For this purpose, the term “401(k) Plan” means any plan intended to be qualified under Code Section 401(a) which includes a cash or deferred arrangement intended to qualify under Code Section 401(k). The Company shall provide Parent with a copy of resolutions duly adopted by the Company’s board of directors so terminating any such 401(k) Plan. If elected by employees of the Company and its Subsidiaries who continue employment and who have participated in the Company 401(k) plan, Parent shall cause its 401(k) Plan to accept distributions from Continuing Employees’ 401(k) accounts as rollover distributions subject to the terms of the Parent 401(k) Plan and the rules and regulations under Section 402(c) of the Code.

(c) Nothing contained in this Section 6.3 shall (i) limit or preclude the Company or Parent from amending or terminating any Employee Benefit Plan or (ii) amend, or be deemed to amend, any Employee Benefit Plan.

(d) Notwithstanding anything to the contrary contained in this Agreement, this Section 6.3 is for the sole benefit of the parties to this Agreement and nothing contained in this Agreement, expressed or implied, shall give or be construed to give to any Person (including, without limitation, any Company employee or any representative, dependent or heir thereof), other than the parties hereto, any legal or equitable rights, remedy or claim hereunder or to amend or modify the terms of any Company Employee Benefit Plan.

(e) Parent and the Surviving Corporation shall be responsible for any obligations and liabilities arising under the WARN Act due to Parent’s or the Surviving Corporation’s actions or omissions following the Closing, including with respect to any termination of employees of the Company following the Closing.

Section 6.4 Further Assurances. Following the Closing, the parties shall cooperate reasonably with each other and with their respective representatives and agents in connection with any steps required to be taken as part of their respective obligations under this Agreement, and the parties agree (a) to execute and deliver to each other such other documents, and (b) to do such other acts and things, all as the other parties may reasonably request, for the purpose of carrying out the intent of this Agreement and the transactions contemplated hereby.

Section 6.5 Consent of Stockholders. Company will take all action necessary in accordance with applicable Legal Requirements and its Organizational Documents to solicit written consents from its stockholders to vote upon the approval of this Agreement and the Merger. All notices and other information delivered to the stockholders of Company relating to the solicitation of consents shall be subject to the prior review and approval of Parent, which approval shall not be unreasonably withheld, conditioned or delayed. The Company will use its commercially reasonable efforts to cause each Former Stakeholder to ratify the appointment of the Stockholders’ Representative pursuant to Section 10.13 hereof, and to provide evidence of the same to Parent.

Section 6.6 List of Former Stakeholders. Prior to Closing, the Company shall deliver to Parent a correct and complete schedule that sets forth as of the Effective Time (i) the number of shares of

Company Capital Stock that each current stockholder of the Company holds of record and (ii) the name of each person who holds an Unexercised Option and the exercise price and number of shares issuable upon exercise of each Unexercised Option.

Section 6.7 Indemnification, Exculpation.

(a) All rights to indemnification or exculpation (including advancement of expenses) existing as of the date of this Agreement in favor of the current or former directors, officers and employees of the Company and its Subsidiaries as provided in the Organizational Documents of the Company and its Subsidiaries shall continue in full force and effect for a period of six (6) years after the Closing; provided, however, that if any claims are asserted or made within such period, all rights to indemnification (and to advancement of expenses) thereunder shall continue until disposition of any such claims. Parent shall not, and shall cause the Surviving Corporation not to, take any action to diminish or impair the indemnification and exculpation provisions existing in the Organizational Documents of the Surviving Corporation as of immediately prior to the Effective Time. The foregoing provision is a contract right in favor of the current or former directors, officers and employees of the Company and its Subsidiaries and shall not be adversely effected by any modification to the Organizational Documents of the Company and its Subsidiaries after the date hereof.

(b) Prior to the Closing, the Company shall purchase, and after the Closing Parent shall, or shall cause the Surviving Corporation to, maintain, an extended reporting period endorsement under the Company’s existing directors’ and officers’ liability insurance coverage for the directors and officers of the Company and its Subsidiaries in a form reasonably satisfactory to Parent that shall provide such directors and officers with coverage for six (6) years following the Closing of not less than the existing coverage and have other terms not materially less favorable to the insured than the directors’ and officers’ insurance currently maintained by the Company.

(c) The provisions of this Section 6.7 are (i) intended to be for the benefit of, and shall be enforceable by, each Person entitled to be indemnification pursuant to this Section 6.7, and each such person’s heirs, legatees, representatives, successors and assigns, it being expressly agreed that such Persons shall be third party beneficiaries of this Section 6.7 and (ii) shall not be subject to amendment by the parties to this Agreement. The indemnification obligations provided under this Section 6.7 are primary and the indemnified Persons under this Section 6.7 shall not be obligated to pursue claims that exist under any other agreement or document which may provide such Person with any rights of indemnification or exculpation.

(d) Parent, Merger Sub and the Surviving Corporation hereby acknowledge that the Indemnified Persons under this Section 6.7 may have certain rights to indemnification, advancement of expenses and/or insurance provided by current shareholders, members, or other Affiliates of the Company or its shareholders (“Indemnitee Affiliates”) separate from the indemnification obligations of Parent, Merger Sub and the Surviving Corporation hereunder. Parent, Merger Sub and the Surviving Corporation hereby agree (i) that the Surviving Corporation is the indemnitor of first resort (i.e., its obligations to the indemnified Persons under this Section 6.7 are primary and any obligation of any Indemnitee Affiliate to advance expenses or to provide indemnification for the same expenses or liabilities incurred by the indemnified Persons under this Section 6.7 are secondary), and (ii) that Parent, Merger Sub and the Surviving Corporation irrevocably waive, relinquish and release the Indemnitee Affiliates from any and all claims against the Indemnitee Affiliates for contribution, subrogation or any other recovery of any kind in respect thereof.

ARTICLE VII.
TAX MATTERS

The following provisions shall govern the allocation of responsibility as between Parent and the Stockholders’ Representative for certain tax matters following the Closing Date:

Section 7.1 Straddle Periods. For purposes of this Agreement, whenever it is necessary to determine the liability for Taxes of the Company and its Subsidiaries for any taxable period of the Company and its Subsidiaries that includes (but does not end on) the Closing Date (a “Straddle Period”), the determination of the Taxes of the Company and its Subsidiaries for the portion of the Straddle Period ending on and including, and the portion of the Straddle Period beginning after, the Closing Date shall be determined by assuming that the Straddle Period consisted of two (2) taxable years or periods, one which ended at the close of the Closing Date and the other which began at the beginning of the day following the Closing Date, and items of income, gain, deduction, loss or credit, and state and local apportionment factors of the Company and its Subsidiaries for the Straddle Period, shall be allocated between such two taxable years or periods on a “closing of the books basis” by assuming that the books of the Company and its Subsidiaries were closed at the close of the Closing Date. However, (i) exemptions, allowances or deductions that are calculated on an annual basis, such as the deduction for depreciation, and (ii) periodic taxes such as real and personal property taxes shall be apportioned ratably between such periods on a daily basis.

Section 7.2 Responsibility for Filing Tax Returns.

(a) Filing of Tax Returns. Parent shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Company and its Subsidiaries that are required to be filed after the Closing Date and pay all Taxes shown as due on those Tax Returns. All such Tax Returns relating to a Pre-Closing Tax Period or a Straddle Period shall be prepared in a manner consistent with the past practices of the Company and its Subsidiaries, unless Parent reasonably determines that such past practices are not consistent with applicable Legal Requirements. Without the prior written consent of the Stockholders’ Representative (which consent may not be unreasonably withheld or delayed), the Surviving Corporation shall not amend any Tax Return relating to a Pre-Closing Tax Period or Straddle Period.

(b) Review Rights. No later than thirty (30) days prior to the due date for filing thereof, Parent shall provide the Stockholders’ Representative with drafts of all Tax Returns prepared by it pursuant to Section 7.2(a), but only to the extent such Tax Returns would reasonably be expected to result in a Tax liability subject to indemnification pursuant to Section 8.2 of this Agreement. The Stockholders’ Representative shall have the right to review and provide comments on such Tax Returns during the fifteen (15) day period following the receipt of such Tax Returns. The Stockholders’ Representative and Parent shall consult with each other and attempt in good faith to resolve any issues arising as a result of any Tax Returns described in this Section 7.2(b). Upon resolution of all such items, the relevant Tax Return shall be timely filed on that basis. If any dispute with respect to a Tax Return is not resolved prior to the due date of such Tax Return, such Tax Return shall be filed in the manner which Parent deems correct, without prejudice to any party’s rights and obligations under this Article VII and Article VIII.

Section 7.3 Certain Actions. Parent covenants that without the prior consent of the Stockholders’ Representative, it shall not, and shall not cause or permit the Surviving Corporation or any of its Subsidiaries or any Affiliates of Parent, to make or change any material Tax election (including

making any election under Section 338 of the Code), take any Tax position on any Tax Return relating to a Pre-Closing Tax Period, or compromise or settle any Tax liability , in each case if such action would have the effect of materially increasing the Tax liability (or Tax indemnity) or materially reducing any Tax asset of any Stockholder in respect of any Pre-Closing Tax Period. If Parent breaches the foregoing covenant, such Stockholder shall not be liable for any Taxes that are a direct or indirect result of such breach. After the Closing Date, Parent and its Affiliates shall not, without the consent of the Stockholders’ Representative, agree to the waiver or any extension of the statute of limitations relating to any Taxes of the Company or any of its Subsidiaries for any Pre-Closing Tax Period or any Straddle Period.

Section 7.4 Tax Proceedings. The Surviving Corporation shall promptly notify the Stockholders’ Representative in writing upon receipt by the Surviving Corporation or any of its Subsidiaries of notice of any Tax audits, examinations or assessments that could give rise to any indemnification pursuant to Section 8.2. Any such audit shall be treated as a Third Party Claim subject to Section 8.6.

Section 7.5 Cooperation on Tax Matters

(a) Parent and the Stockholders’ Representative shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to this Article VII and any audit, litigation or other Proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Stockholders’ Representative and Parent agree (i) to retain all books and records with respect to Tax matters pertinent to the Company or any Subsidiary of the Company relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Parent or the Stockholders’ Representative, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (ii) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if Parent so requests, the Stockholders’ Representative shall allow Parent to take possession of such books and records in lieu of destruction.

(b) Parent, the Stockholders’ Representative and the Company further agree, upon request, to use their commercially reasonable efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed in connection with the transactions contemplated hereby.

Section 7.6 Transfer Taxes. Any transfer, documentary, sales, use, stamp, registration and other similar Taxes and fees (including any penalties and interest) incurred in connection with this Agreement shall be borne 50% by the Former Stakeholders (which fees the Stockholders’ Representative will pay to Parent) and 50% by Parent.

Section 7.7 Tax Refunds. Any Tax Refunds, less any expenses incurred by Parent, the Surviving Corporation or any Subsidiary in seeking such Tax Refunds, that are received by the Surviving Corporation or any of its Subsidiaries within 12 months following to the Closing Date, or with respect to which Parent, the Surviving Corporation or any Subsidiary files a claim for refund within the 12 months following the Closing Date, that are attributable to any Tax period (or portion thereof) ending on or prior to the Closing Date shall be for the account of the Former Stakeholders and shall be forwarded by Parent

to the Stockholders’ Representative on behalf of such Former Stakeholders promptly upon receipt, except to the extent that such Tax Refund arises as a result of a carryback of a loss or other Tax benefit attributable to a period (or portion thereof) beginning after the Closing Date. For the avoidance of doubt, any Tax Refund attributable to the use of any Tax net operating loss, capital loss or other carryforward in any Tax period beginning after the Closing Date shall be retained by Parent, the Surviving Corporation or the Subsidiaries, as applicable. Parent shall, if the Stockholders’ Representative reasonably requests, file or cause the relevant entity (Parent, the Surviving Corporation or any Subsidiaries of the Company or any successor) to file a claim for refund for any Tax Refunds for which the Stockholders’ Representative reasonably believes the Former Stakeholders are entitled to a Tax Refund. The Stockholders’ Representative shall prepare, or cause to be prepared, any such claim for refund.

ARTICLE VIII.
INDEMNIFICATION

Section 8.1 Survival. All representations, warranties, covenants, and agreements in this Agreement, the Schedules attached hereto, the certificates delivered pursuant to Section 1.16, and any other certificate or document (including any Letter of Transmittal) delivered pursuant to this Agreement will survive the Closing and the consummation of the transactions contemplated hereby, subject only to Section 8.5. The right to indemnification, reimbursement, or other remedy based on such representations, warranties, covenants and obligations will not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) about, the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or obligation. Notwithstanding anything contained in this Agreement to the contrary, no party shall bring any claim alleging a breach of Section 4.4(b) against any other party following the Closing, and in no event shall the failure of any party to comply with the covenant contained in Section 4.4(b) of this Agreement be asserted as a defense against any claim for indemnification pursuant to this Article VIII.

Section 8.2 Indemnification and Reimbursement by the Former Stakeholders. Subject to the limitations set forth in this Article VIII, from and after the Closing, the Former Stakeholders shall severally defend, indemnify and hold harmless Parent, Merger Sub, their respective Affiliates, and their respective officers, directors, stockholders, employees, representatives, agents, successors and assigns (collectively, the “Parent Indemnified Persons”) from, and shall reimburse the Parent Indemnified Persons out of the Escrow Fund for, any Loss, whether or not involving a third-party claim (collectively, “Damages”), arising from, in connection with, or relating to:

(a) Except as addressed specifically in another clause of this Section 8.2, any breach of any representation or warranty made by the Company in this Agreement, any certificate delivered by the Company pursuant to Section 1.16(a), or any other certificate or document delivered by the Company at Closing pursuant to this Agreement, in each case disregarding the terms “material,” “materiality,” and “Company Material Adverse Effect”; (provided, however, that such “material”, “materiality” and “Company Material Adverse Effect” qualifications and limitations shall not be disregarded in Section 2.14(a)(xi) and the first sentence of Section 2.19);

(b) any non-fulfillment or breach of any covenant, agreement or obligation contained in this Agreement to be performed or complied with by the Company prior to Closing;

(c) that portion of Damages allocable to the Company or any Company Subsidiary in connection with any written settlement relating to any Proceeding against the Surviving Corporation, any Company Subsidiary or any Parent Indemnified Person brought by a Governmental Authority after the

Closing Date alleging a violation of any Healthcare Law that, if successful, would give rise to or evidence a breach of any representation or warranty made by the Company in this Agreement; provided, that for the avoidance of doubt, the foregoing shall be subject to the consent requirements set forth in Section 8.6;

(d) any breach of any representation or warranty made by the Company in (i) the first two sentences of Section 2.1 and (ii) Sections 2.2(a), 2.4 and 2.7 of this Agreement, in each case disregarding the terms “material,” “materiality,” and “Company Material Adverse Effect”;

(e) payments made to stockholders holding Dissenting Shares in excess of the consideration such stockholders would have been entitled to receive pursuant to this Agreement had they not been Dissenting Shares; and

(f) any costs and expenses reasonably incurred (including reasonable attorneys’ fees and disbursements and the costs of litigation and investigation) and any payments by the Surviving Corporation or its Affiliates to holders of Unexercised Options who do not execute and deliver to the Company an Option Cancellation Agreement at or prior to the Closing, in connection with the cancellation of all Unexercised Options.

For avoidance of doubt, the Company shall have no liability to, or obligation to indemnify, the Parent Indemnified Persons from and after the Closing.

Section 8.3 Indemnification and Reimbursement by Parent. Subject to the limitations set forth in this Article VIII, from and after the Closing, Parent shall defend, indemnify and hold harmless the Former Stakeholders and their respective officers, directors, stockholders, employees, representatives, agents, successors and assigns (collectively, the “Former Stakeholder Indemnified Persons”) from, and shall reimburse the Former Stakeholder Indemnified Persons for, any Damages directly or indirectly arising from or in connection with, incidental or relating to:

(a) any breach of any representation or warranty made by Parent or Merger Sub in this Agreement, the certificate delivered by Parent pursuant to Section 1.16(b), or any certificate or document delivered by Parent or Merger Sub at Closing pursuant to this Agreement, in each case disregarding the terms “material” and “materiality”; and

(b) any non-fulfillment or breach of any covenant, agreement or obligation of Parent or Merger Sub or the Surviving Corporation in this Agreement.

Section 8.4 Limitations on Indemnification by the Former Stakeholders. Notwithstanding anything contained herein to the contrary, the obligation of the Former Stakeholders to indemnify the Parent Indemnified Persons pursuant to Section 8.2 is subject to the following limitations and qualifications:

(a) The Former Stakeholders will have no indemnification liability for any single Loss (or series of related Losses) that does not exceed $50,000 (the “Mini-Basket”).

(b) The Former Stakeholders will have no indemnification liability under Sections 8.2(a) through (c) until the total amount of Losses (other than Losses disregarded pursuant to Section 8.4(a)) incurred by the Parent Indemnified Persons thereunder exceeds $1,000,000 (the “Basket”), in which case the Stockholders will be responsible for the amount of the Losses in excess of the Basket.

(c) The Former Stakeholders shall have no indemnification liability for Damages under Section 8.2 in an amount in excess of the amount remaining from time to time in the Escrow Fund, if any (the “Cap”).

(d) The limitations set forth in clauses (a) and (b) of this Section 8.4 shall not apply to Damages pursuant to Sections 8.2(d), (e) and (f). For avoidance of doubt, nothing contained herein (including Sections 8.4(a) through (c)) shall limit or restrict any Parent Indemnified Person’s right to maintain or recover any amounts from one or more Former Stakeholders in connection with any action or claim based upon any fraud committed by such Former Stakeholder (but no Former Stakeholder shall have any liability for the fraud of any other Person).

(e) All Damages relating to claims for indemnification pursuant to Section 8.2 shall be satisfied solely out of the amount remaining from time to time in the Escrow Fund, if any. In no event shall any Former Stakeholder be obligated to reimburse, replenish or make any further contribution (in cash or in kind) to the Escrow Fund following the Closing.

(f) In addition to the indemnification obligations of the Former Stakeholders pursuant to Section 8.2, each Former Stakeholder that executes and delivers a Letter of Transmittal shall indemnify the Parent Indemnified Persons to the extent provided therein. Any claim arising out of a Letter of Transmittal shall solely be pursued directly against the applicable Former Stakeholder and any Damages relating to such claim shall be paid by the Former Stakeholder and shall not be paid out of the Escrow Fund.

Section 8.5 Time Limitations.

(a) Former Stakeholders will have no indemnification liability for the breach of any representation or warranty or covenant set forth in this Agreement (or for any obligations under Section 8.2(c)) unless on or before the twelve (12) month anniversary of the Closing Date, Parent notifies Stockholders’ Representative of a claim or potential claim made by Parent in good faith specifying the factual basis of that claim or potential claim in reasonable detail to the extent then known by Parent; provided, however, that any claim in connection with any action or claim based upon fraud, shall survive and, in each case, may be made by Parent at any time prior to thirty (30) days following the expiration of the applicable statute of limitations period.

(b) Parent will have no indemnification liability for the breach of any representation or warranty set forth in Article III, unless on or before the twelve (12) month anniversary of the Closing Date, Stockholders’ Representative notifies Parent of a claim or potential claim made by Stockholders’ Representative in good faith specifying the factual basis of that claim or potential claim in reasonable detail to the extent then known by Stockholders’ Representative; provided, however, that any claim in connection with any action or claim based upon fraud, shall survive and, in each case, may be made by Stockholders’ Representative at any time prior to thirty (30) days following the expiration of the applicable statute of limitations period.

(c) Upon the giving of notice specified in Sections 8.5(a) or (b), as the case may be, the indemnity with respect thereto shall survive the time at which it would otherwise terminate pursuant to this Agreement (regardless of when the Damages in respect thereof may actually be incurred), and the indemnitee shall have the right to commence legal proceedings with respect to any such noticed claim or potential claim subsequent to the survival date for the enforcement of their rights under this Article VIII.

Section 8.6 Third-Party Claims.

(a) Promptly after receipt by a Person entitled to indemnity under Sections 8.2 or 8.3 (an “Indemnified Person”) of notice of the assertion of any claim against any Indemnified Person by a third party (a “Third-Party Claim”), such Indemnified Person shall give notice to the Person obligated to indemnify under such section (an “Indemnifying Person”) of the assertion of such Third-Party Claim, provided that the failure to notify the Indemnifying Person will not relieve the Indemnifying Person of any liability that it may have to any Indemnified Person, except to the extent that (and only to the extent that) such failure is demonstrated by the Indemnifying Person to have actually caused the Damages for which it is obligated to pay hereunder to be greater than such Damages that would have been payable had the Indemnified Person given the prompt notice required hereby. Such notice shall be accompanied by copies of all relevant documentation with respect to such Third Party Claim, including any summons, complaint or other pleading that may have been served, any written demand or any other relevant document or instrument.

(b) If an Indemnified Person gives notice to the Indemnifying Person pursuant to Section 8.6(a) of the assertion of a Third-Party Claim, the Indemnifying Person shall be entitled to participate in the defense of such Third-Party Claim at its own cost and expense and, to the extent that it wishes (unless (i) the Indemnifying Person is also a Person against whom the Third-Party Claim is made and the Indemnified Person determines in good faith based upon the advice of counsel that joint representation would be inappropriate, (ii) the Indemnifying Person fails to provide reasonable assurance to the Indemnified Person of its financial capacity to defend such Third-Party Claim, or (iii) Parent asserts a claim against the Escrow Fund and the amount of Damages sought in the Third-Party Claim is greater than the amount remaining in the Escrow Fund), to assume the defense of such Third-Party Claim with counsel satisfactory to the Indemnified Person, subject to the Indemnified Person’s right to participate in such defense at its own expense. After notice from the Indemnifying Person to the Indemnified Person of its election to assume the defense of such Third-Party Claim, the Indemnifying Person shall not, so long as it diligently conducts such defense, be liable to the Indemnified Person under this Article VIII for any fees of the Indemnified Person’s counsel with respect to the defense of such Third-Party Claim subsequently incurred by the Indemnified Person in connection with the defense of such Third-Party Claim, other than reasonable costs of investigation or to the extent incurred at the Indemnifying Person’s request in connection with its defense of the claim. If the Indemnifying Person assumes control of the defense of a Third-Party Claim, (i) such assumption will conclusively establish for purposes of this Agreement that the claims made in that Third-Party Claim are within the scope of and subject to indemnification, (ii) no compromise or settlement of such Third-Party Claims may be effected by the Indemnifying Person without the Indemnified Person’s consent (which shall not be unreasonably withheld, conditioned or delayed) unless (A) there is no finding or admission of any violation of any Legal Requirement or any violation of the rights of any Person; (B) the sole relief provided is monetary damages that are paid in full by the Indemnifying Person or out of the Escrow Fund; and (iii) the Indemnified Person shall have no liability with respect to any compromise or settlement of such Third-Party Claims effected without its consent. If notice is given to an Indemnifying Person of the assertion of any Third-Party Claim and the Indemnifying Person does not, within ten (10) days after the Indemnified Person’s notice is given, give notice to the Indemnified Person of its election to assume the defense of such Third-Party Claim, then the Indemnified Person can manage such Third Party Claim in accordance with the terms and conditions herein. Whether or not the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the Indemnifying Party’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed).

(c) Notwithstanding the foregoing, if an Indemnified Person determines in good faith based upon the advice of counsel that there is a reasonable probability that a Third-Party Claim may adversely affect it or its Affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, or such Third-Party Claim involves any material matter beyond the scope of or in excess of the indemnification obligations hereunder, the Indemnified Person may, by notice to the Indemnifying Person, assume the exclusive right to defend, compromise or settle such Third-Party Claim, but the Indemnifying Person will not be bound by any determination of any Third-Party Claim so defended for the purposes of this Agreement or any compromise or settlement effected without its consent (which consent may not be unreasonably withheld, conditioned or delayed) and, for the avoidance of doubt, the Indemnifying Person shall not be obligated to indemnify any Person pursuant to Section 8.2(c) in connection with any compromise or settlement effected without its consent (which consent may not be unreasonably withheld, conditioned or delayed).

(d) With respect to any Third-Party Claim subject to indemnification under this Article VIII: (i) both the Indemnified Person and the Indemnifying Person, as the case may be, shall keep the other Person fully informed in all material respects of the status of such Third-Party Claim and any related proceedings at all stages thereof where such Person is not represented by its own counsel, and (ii) the parties agree to render to each other such assistance as they may reasonably require of each other and to cooperate in good faith with each other in order to ensure the proper and adequate defense of any Third-Party Claim.

(e) With respect to any Third-Party Claim subject to indemnification under this Article VIII, the parties shall cooperate in such a manner as to preserve in full (to the extent possible) the confidentiality of all Confidential Information and the attorney-client and work-product privileges. In connection therewith, each party agrees that: (i) it will use commercially reasonable efforts, in respect of any Third-Party Claim in which it has assumed or has participated in the defense, to avoid production of Confidential Information (consistent with applicable law and rules of procedure), and (ii) all communications between any parties hereto and counsel responsible for or participating in the defense of any third-party claim will, to the extent possible, be made so as to preserve any applicable attorney-client or work-product privilege.

Section 8.7 Procedure For Indemnification — Other Claims. Subject to the other provisions of this Article VIII, a claim for indemnification for any matter not involving a Third-Party Claim may be asserted by notice to the party from whom indemnification is sought.

Section 8.8 Calculation of Damages. For purposes of calculating the amount of Damages to which the Parent Indemnified Persons and Former Stakeholder Indemnified Persons are entitled under this Article VIII, the terms “material,” “materiality,” and “Company Material Adverse Effect” will be disregarded (provided, however, that such “material”, “materiality” and “Material Adverse Effect” qualifications and limitations shall not be disregarded in, Section 2.14(a)(xi) and the first sentence of Section 2.19).

Section 8.9 Tax Benefit Offset. To the extent an Indemnified Person recognizes any Indemnification Tax Benefit (as defined below) as a result of any Damages, the Indemnified Person shall pay the amount of such Indemnification Tax Benefit (but not in excess of the indemnification payment or payments actually received from the Indemnifying Party with respect to such Damages) to the Indemnifying Person within 60 calendar days of such Indemnification Tax Benefits being actually recognized by the Indemnified Person (to the extent such Indemnification Tax Benefit are actually recognized prior to the payment of the Damages, the amount of Damages shall be reduced by the amount

of Indemnification Tax Benefit actually recognized). For this purpose, the Indemnified Person shall be deemed to recognize an indemnification tax benefit (“Indemnification Tax Benefit”) with respect to a taxable year if, and to the extent that, the Indemnified Person’s liability for Taxes for such taxable year, calculated by excluding any Tax items attributed to the Damages for all taxable years, exceeds the Indemnified Person’s actual liability for Taxes for such taxable year, calculated by taking into account any Tax items attributed to the Damages.

Section 8.10 Remedies Exclusive. From and after the Closing Date, except in connection with any action or claim based upon fraud, the remedies provided for in this Article VIII shall be exclusive remedy available to the parties hereto with respect to the breach of any representation, warranty, covenant or obligation contained in this Agreement. If any party or Former Stakeholder commits fraud, then only such party or Former Stakeholder who committed such fraud will be liable for such fraud and no party or Former Stakeholder shall be liable for any fraud committed by any other party or Former Stakeholder.

Section 8.11 Treatment of Indemnification Payments. Any payments made pursuant to the indemnification obligations arising under this Agreement shall be treated as an adjustment to the Merger Consideration for all Tax purposes.

Section 8.12 Mitigation. The parties shall cooperate with each other to resolve any claim or liability with respect to which an Indemnifying Person is obligated to indemnify an Indemnified Person hereunder, including by making commercially reasonable efforts to mitigate Damages. In connection with any Damages for which an Indemnified Person may seek indemnification under this Article VIII, such Indemnified Person shall use its commercially reasonable efforts to pursue available insurance coverage that such Indemnified Person has in respect of such Damages and the amount of insurance proceeds actually received by the Indemnified Person, less any deductibles, shall not be included in Losses that such Indemnified Person may recover under this Article VIII. Any out-of-pocket fees and expenses (including attorneys’ fees and expenses) incurred by such Indemnified Person pursuing such insurance coverage shall constitute Losses for purposes of Article VIII. If the Indemnified Person receives any insurance proceeds subsequent to an indemnification payment by the Indemnifying Person in respect of such Losses and (a) the Indemnified Person has not been fully reimbursed for all such Losses by such indemnification payment from the Indemnifying Person, then the Indemnified Person shall keep the portion of such insurance proceeds necessary to fully reimburse the Indemnified Person for all such Losses and shall promptly pay the remainder of such insurance proceeds to the Indemnifying Person with respect to any indemnification payment made to the Indemnified Person up to the amount of the insurance proceeds so received by the Indemnified Person and (b) the Indemnified Person has been fully reimbursed for all such Losses by such indemnification payment from the Indemnifying Person, then such Indemnified Person shall promptly reimburse the Indemnifying Person for any indemnification payment made to the Indemnified Person up to the amount of the insurance proceeds so received by the Indemnified Person.

ARTICLE IX.
TERMINATION

Section 9.1 Termination Events. By written notice given prior to or at the Closing, this Agreement may be terminated as follows:

(a) by Parent, in the event that following the date of this Agreement Parent obtains Knowledge of breaches of the representations and warranties of the Company contained in Sections

2.5(b), 2.11, 2.16 or 2.17 of this Agreement that would be reasonably expected to result in Damages in excess of $7,000,000;

(b) by Parent, if the satisfaction of any of the conditions to Parent’s and Merger Sub’s obligation to close the transactions contemplated hereby as set forth in Section 5.1 becomes impossible or otherwise incapable of cure by September 30, 2011 (other than through the failure of Parent or Merger Sub to comply with its obligations under this Agreement), and Parent has not waived such condition in writing on or before such date;

(c) by the Stockholders’ Representative, if the satisfaction of any of the conditions to the Company’s obligation to close the transactions contemplated hereby as set forth in Section 5.2 becomes impossible or otherwise incapable of cure by September 30, 2011 (other than through the failure of the Company to comply with its obligations under this Agreement), and the Stockholders’ Representative has not waived such condition in writing on or before such date;

(d) by either Parent or the Stockholders’ Representative, if any Order of any Governmental Authority of competent jurisdiction permanently restraining, enjoining or otherwise preventing the consummation of the transactions contemplated hereby has been issued and becomes final and non-appealable;

(e) by mutual written consent of Parent and the Stockholders’ Representative; or

(f) by Parent or the Stockholders’ Representative, if the Closing has not occurred on or before September 30, 2011 or such later date as Parent and the Stockholders’ Representative may agree upon in writing.

Section 9.2 Effect of Termination. If the Agreement is terminated pursuant to Section 9.1, all obligations of the parties under this Agreement will terminate, except that the obligations in Section 4.11, Section 6.1; Section 6.2(a), this Article IX and Article X will survive; provided, however, that termination of this Agreement will not preclude a party from bringing a claim against any other party to this Agreement for a breach arising prior to such termination or to compel specific performance by another party of its obligations under this Agreement. Nothing in this Article IX shall be deemed to release any party from any liability for any willful breach (but not any other breach) by such party of the terms and provisions of this Agreement, to impair the right of any party to compel specific performance by any other party of his, her or its obligations under this Agreement or to limit the right of any party to commence any Proceeding for improper or wrongful termination of this Agreement. For the avoidance of doubt, such phrase “willful breach” shall be interpreted throughout this Agreement to mean that the “willfully breaching” party acted purposely with Knowledge that his or its actions were in breach of the terms of this Agreement.

ARTICLE X.
GENERAL PROVISIONS

Section 10.1 Expenses. Except as otherwise expressly provided by this Agreement, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby by the Company prior to Closing shall be paid by the Company (and, to the extent not paid by the Company or its Subsidiaries as of Closing, shall be deducted from the Merger Consideration as Transaction Expenses pursuant to the terms hereof), and all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby by Parent and Merger Sub shall be paid by Parent. Notwithstanding

the foregoing, Parent will pay one-half and the Stockholders Representative will pay (from amounts in the Reserve Account) one-half of the fees and expenses of the Escrow Agent under the Escrow Agreement.

Section 10.2 Assignment; No Third Party Beneficiaries. No party may assign any of its rights or delegate any of its obligations under this Agreement without the prior written consent of the other parties, except that Parent may assign any of its rights and delegate any of its obligations under this Agreement (i) to any Affiliate of Parent, and (ii) may collaterally assign its rights hereunder to any financial institution providing financing to Parent in connection with the transactions contemplated hereby, provided that no such assignment or delegation will relieve Parent from any of its obligations hereunder or require the other parties to this Agreement to resort to any such assignee or transferee prior to seeking any remedies against the assigning or transferring party permitted under or pursuant to this Agreement. Subject to the preceding sentence, this Agreement will apply to, be binding in all respects upon, and inure to the benefit of the successors and permitted assigns of the parties. Except as set forth in Section 6.8, nothing in this Agreement will be construed to give any Person other than the parties to this Agreement and the Former Stakeholders any legal or equitable right under or with respect to this Agreement or any provision of this Agreement, except such rights as will inure to a permitted successor or assignee pursuant to this Section 10.2.

Section 10.4 Entire Agreement; Disclosure Schedules. This Agreement (together with the Annexes, Schedules and Exhibits attached to this Agreement and the other documents and supplements delivered pursuant to this Agreement) constitutes the entire agreement among the parties and supersedes all prior agreements, whether written or oral, between the parties with respect to the subject matter hereof

and thereof (other than the Confidentiality Agreement, which will remain in full force and effect). No exceptions to any representations or warranties disclosed on one schedule shall constitute an exception to any other representations or warranties made in this Agreement unless its relevance or applicability to information called for by any other Company Disclosure Schedule is reasonably apparent. The inclusion of an item in the Company Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by the Company that such item represents an exception or material fact, event or circumstance or that such item constitutes a Company Material Adverse Effect.

Section 10.5 Amendment; Waiver; Remedies Cumulative. This Agreement may not be amended and any terms or conditions may not be waived except by a written agreement signed by the Parent, Merger Sub and the Stockholders’ Representative. Neither the failure nor any delay by any party in exercising any right under this Agreement or the documents referred to in this Agreement will operate as a waiver of such right, and no single or partial exercise of any such right will preclude any other or further exercise of such right or the exercise of any other right. The waiver, in accordance with Article V above, of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, will not affect the right to indemnification, reimbursement or other remedy based on such representation, warranty, covenant or obligation. To the maximum extent permitted by Legal Requirements, (a) no waiver that may be given by a party will be applicable except in the specific instance for which it is given; and (b) no notice to or demand on one party will be deemed to be a waiver of any obligation of such party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement. The rights and remedies of the parties to this Agreement are cumulative and not alternative.

Section 10.6 Severability. If any provision of this Agreement is adjudicated by a court of competent jurisdiction to be invalid or unenforceable for any reason, such provision shall be ineffective to the extent of such invalidity or unenforceability; provided, however, that the remaining provisions will continue in full force and effect without being impaired or invalidated in any way unless such invalid or unenforceable provision or clause is so significant as to materially affect the expectations of Parent and the Company regarding this Agreement. Otherwise, any invalid or unenforceable provision shall be replaced by the Parent and the Stockholders’ Representative with a valid provision which most closely approximates the intent and economic effect of the invalid or unenforceable provision.

Section 10.7 Headings; Construction. The headings of Articles and Sections in this Agreement are provided for convenience only and will not affect its construction or interpretation. All Annexes, Exhibits and Schedules to this Agreement are incorporated into and constitute an integral part of this Agreement as if fully set forth herein. All words used in this Agreement will be construed to be of such gender or number as the context requires. The word “including” shall be read as “including but not limited to” and otherwise shall be considered illustrative and non-limiting. All references to dollars or “$” in this Agreement will be to U.S. dollars. Unless expressly provided otherwise, all references to “ordinary course of business” shall mean consistent with past practice and custom (including, without limitation, with respect to amount, timing, scope, quality, quantity and frequency). The language used in the Agreement will be construed, in all cases, according to its fair meaning, and not for or against any party hereto. The parties acknowledge that each party has reviewed this Agreement with competent counsel of its choosing and that rules of construction to the effect that any ambiguities are to be resolved against the drafting party will not be available in the interpretation of this Agreement.

Section 10.8 Execution of Agreement; Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original copy of this Agreement and all

of which, when taken together, will be deemed to constitute one and the same agreement. The exchange of copies of this Agreement and of signature pages by facsimile, or by .pdf or similar imaging transmission, will constitute effective execution and delivery of this Agreement as to the parties and may be used in lieu of the original Agreement for all purposes. Signatures of the parties transmitted by facsimile, or by .pdf or similar imaging transmission, will be deemed to be their original signatures for any purpose whatsoever.

Section 10.9 Governing Law. This Agreement, and any claims that arise out of or result from this Agreement, will be governed by and construed under the laws of the State of Delaware without regard to any conflicts of laws principles that would require the application of any other law.

Section 10.10 Enforcement of Agreement. The Company and Parent acknowledge and agree that the other party would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement by the Company or Parent could not be adequately compensated by monetary damages. Accordingly, the Company and Parent agree that, in addition to any other right or remedy to which the Company or Parent, as applicable, may be entitled, at law or in equity, it will 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 the provisions of this Agreement, without posting any bond or other undertaking.

Section 10.11 Waiver of Jury Trial. TO THE EXTENT NOT PROHIBITED BY LEGAL REQUIREMENT THAT CANNOT BE WAIVED, THE PARTIES HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING ARISING OUT OF OR IN ANY WAY PERTAINING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, WHETHER NOW OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE. ANY PARTY MAY FILE A COPY OF THIS SECTION 10.11 WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED AGREEMENT BETWEEN THE PARTIES TO IRREVOCABLY WAIVE TRIAL BY JURY, AND THAT ANY PROCEEDING OR ACTION WHATSOEVER BETWEEN THE PARTIES RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY WILL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A TRIAL.

Section 10.12 Independence of Covenants, Representations and Warranties. All covenants hereunder shall be given independent effect so that if a certain action or condition constitutes a default under a certain covenant, the fact that such action or condition is permitted by another covenant shall not affect the occurrence of such default, unless expressly permitted under an exception to such initial covenant. In addition, subject to Section 10.4, all representations and warranties hereunder shall be given independent effect so that if a particular representation or warranty proves to be incorrect or is breached, the fact that another representation or warranty concerning the same or similar subject matter is correct or is not breached will not affect the incorrectness of or a breach of a representation and warranty hereunder.

Section 10.13 Stockholders’ Representative.

(a) Brazos GP Partners, LLC shall be constituted and appointed as agent (the foregoing person and any other person duly acting in such capacity as authorized hereunder from time to time, the “Stockholders’ Representative”) for and on behalf of each Former Stakeholder to give and receive notices and communications, to agree to, negotiate and enter into, on behalf of the Former

Stakeholders, amendments, consents and waivers under this Agreement pursuant to the terms set forth herein, to make and receive payments on behalf of the Former Stakeholders pursuant to the terms set forth herein, to take such other actions as authorized by this Agreement, including actions in connection with the determination of the Estimated Closing Statement, the Proposed Closing Statement and the Final Closing Statement, and to take all actions necessary or appropriate in the judgment of the Stockholders’ Representative for the accomplishment of the foregoing. Such agency may be changed by a vote or written consent by the holders of a majority of the Company Capital Stock on an as-converted basis as of the Closing Date, voting in the same manner as would have been voted in accordance with the Organizational Documents of the Company as in effect immediately prior to the Closing Date (the “Majority Stockholders”), from time to time upon not less than ten (10) days’ prior written notice to Parent. If at any time the Stockholders’ Representative resigns, dies or becomes incapable of acting, the Majority Stockholders shall immediately choose another Stockholder to act as the Stockholders’ Representative under this Agreement. No such resignation shall be effective until a new Stockholders’ Representative shall be appointed and have confirmed his acceptance of such appointment in writing to Parent. The Former Stakeholder Indemnified Persons may not make a claim for indemnity against Parent pursuant to this Agreement except through the Stockholders’ Representative, who shall make such a claim only upon the written direction of the Majority Stockholders. The Stockholders’ Representative may enforce, prosecute and settle any indemnification related claim without directions from the Former Stakeholders or the Former Stakeholder Indemnified Persons, and all acts and decisions of the Stockholders’ Representative in connection with such matters shall be binding on all the Former Stakeholders and Former Stakeholder Indemnified Persons. No bond shall be required of the Stockholders’ Representative, and the Stockholders’ Representative shall receive no compensation for services provided hereunder, but shall receive reimbursement from, and be indemnified severally by, the Former Stakeholders, in proportion to the aggregate amount of Merger Consideration received by such Former Stakeholders, for any and all Damages or expenses incurred by the Stockholders’ Representative in the performance or discharge of its duties pursuant to this Section 10.13, and, in addition to the foregoing, the Stockholders’ Representative shall be entitled to offset the amount of any such Damages and expenses from any amounts released from the Escrow Fund and the Reserve Account upon its release to the Former Stakeholders prior to the distribution of such funds to the Former Stakeholders in accordance with the terms hereof. Notices or communications to or from the Stockholders’ Representative shall constitute notice to or from each of the Former Stakeholders.

(b) The Stockholders’ Representative will be entitled to engage such counsel, experts and other agents as the Stockholders’ Representative deems necessary or proper in connection with performing the Stockholders’ Representative’s obligations hereunder, and will be promptly reimbursed by the Former Stakeholders for all reasonable expenses, disbursements and advances incurred by the Stockholders’ Representative in such capacity upon demand. Each Former Stakeholder shall indemnify and hold harmless the Stockholders’ Representative pro rata based upon such Former Stakeholders’ pro rata share of the total outstanding shares of the Company Capital Stock on an as-converted basis as of the Closing Date, from any and all Damages that are incurred by the Stockholders’ Representative as a result of actions taken, or actions not taken, by the Stockholders’ Representative herein, except to the extent that such Damages arise from the gross negligence or willful misconduct of the Stockholders’ Representative. The Stockholders’ Representative shall not be liable to the Former Stakeholders for any act done or omitted hereunder as Stockholders’ Representative, excluding acts which constitute gross negligence or willful misconduct.

(c) All amounts received by the Stockholders’ Representative on behalf of the Former Stakeholders under this Agreement will be promptly paid by the Stockholders’ Representative to the Former Stakeholders in the proportions required under this Agreement; provided, however, that the

Stockholders’ Representative will be entitled to set off any amounts payable to the Stockholders’ Representative under Section 10.13 against amounts otherwise payable to the Former Stakeholders pursuant to this Section 10.13.

(d) A decision, act, consent or instruction of the Stockholders’ Representative in respect of any action under this Agreement shall constitute a decision of all of the Former Stakeholders and any other Former Stakeholder Indemnified Persons, whether or not there was any prior consultation with or contrary instructions from any Former Stakeholder, and shall be final, binding and conclusive upon each such Former Stakeholder and other Former Stakeholder Indemnified Persons, and Parent may conclusively rely upon any decision, act, consent or instruction of the Stockholders’ Representative hereunder as being the decision, act, consent or instruction of each and every such Former Stakeholder and any other Former Stakeholder Indemnified Persons. Parent shall be able to rely conclusively on the proper distribution of such amounts by the Stockholders’ Representative among the Former Stakeholders upon receipt by the Stockholders’ Representative of such amounts. Parent is hereby irrevocably relieved from any liability to any Person (including any Former Stakeholder or any other Former Stakeholder Indemnified Persons) for any acts done by them in accordance with such decision, act, consent or instruction of the Stockholders’ Representative.

(e) The holders of two-thirds of the issued and outstanding Company Capital Stock (on a fully-diluted, as-converted basis) immediately prior to the Effective Time may amend this Section 10.13 from time to time following the date hereof and such amendment shall be binding on all Former Stakeholders. Any such amendment shall not be binding on and shall have no effect on Parent or the Surviving Corporation.

Section 10.14 Reserve Account

(a) The Stockholders’ Representative is hereby authorized to establish an account for the purposes set forth herein (the “Reserve Account”). The Stockholders’ Representative is hereby authorized to use the funds in the Reserve Account, or, to the extent the Reserve Account has been satisfied, to use any remaining funds in the Escrow Fund that are to be released to the Former Stakeholders, to satisfy, to the extent there are sufficient funds therefor, (i) all costs, fees, expenses, liabilities or other obligations of the Former Stakeholders or the Stockholders’ Representative hereunder, (including, expenses of attorneys, accountants and other advisors), and (ii) any other obligations or expenses incurred by the Stockholders’ Representative in connection with the performance of its duties under this Agreement and the other agreements entered into in connection herewith.

(b) Any funds remaining in the Reserve Account as of the Survival Date (or, if any indemnification claims remain outstanding on such Survival Date, the date on which all such outstanding claims have been resolved) (the “Reserve Termination Date”) shall be distributed to the Former Stakeholders, in accordance with Section 1.6(b); provided, that the Stockholders’ Representative may in its reasonable discretion authorize the distribution of all or part of the Reserve Account prior to the Reserve Termination. Notwithstanding the foregoing sentence, the Stockholders’ Representative shall retain in the Reserve Account after the Reserve Termination Date, in accordance with the terms of this Agreement, any amount that the Stockholders’ Representative deems in its reasonable discretion to be necessary to satisfy any costs, fees, liabilities or expenses or other obligations of the Former Stakeholders or the Stockholders’ Representative it expects to incur under this Agreement (whether on its behalf or on behalf of the Former Stakeholders) after the Reserve Termination Date or with respect to its defense or settlement of any unresolved actual or potential claims as of the Reserve Termination Date. Any

amounts otherwise payable from the Escrow Fund to any Former Stakeholders may be placed into the Reserve Account at the Stockholders’ Representative’s discretion.

Section 10.15 Legal Representation. Each of the parties to this Agreement hereby agrees that O’Melveny & Myers LLP (“OMM”) may serve as counsel to the Former Stakeholders, on the one hand, and the Company and its Subsidiaries, on the other hand, in connection with the negotiation, preparation, execution, and delivery of this Agreement and the consummation of the transactions contemplated hereby, and that, following consummation of the transactions contemplated hereby, OMM (or any successor) may serve as counsel to the Former Stakeholders in connection with any litigation, claim or obligation arising out of or relating to this Agreement or the transactions contemplated by this Agreement notwithstanding such representation of the Company and/or any of its Subsidiaries, and each of the parties hereto hereby consents thereto and waives any conflict of interest arising therefrom. Each of Parent, Merger Sub and the Surviving Corporation agrees that it will not request any files or records from OMM related to OMM’s services as counsel to the Company or any of its Subsidiaries in connection with the transaction contemplated by this Agreement for purposes of bringing or advancing any claim or potential claim against the Former Stakeholders or the Stockholders’ Representative in connection with this Agreement or any other documents being executed in connection with the consummation of the transactions contemplated hereby.

In connection with the proposed merger of AmSurg Merger Corporation, a Delaware corporation (“Merger Sub”), a wholly-owned subsidiary of AmSurg Corp., a Tennessee corporation (the “Parent”), with and into National Surgical Care, Inc., a Delaware corporation (the “Company”), pursuant to that certain Merger Agreement, dated as of April 7, 2011 (as amended or modified, the “Merger Agreement”), by and among Parent, the Company, Merger Sub, and Brazos GP Partners, LLC, solely as representative of the Former Stakeholders for certain purposes therein (the “Stockholders’ Representative”), the undersigned, being the registered holder(s) of the stock certificate(s) identified in the table above (the “Certificate(s)”), which represent all of the shares of Company Common Stock, Series A Convertible Preferred Stock, Series C Convertible Preferred Stock and Series D Convertible Preferred Stock of the Company, as applicable, owned by the undersigned (collectively the Company Common Stock, Series A Convertible Preferred Stock, Series C Convertible Preferred Stock and Series D Convertible Preferred Stock of the Company, the “NSC Shares”), encloses herewith, delivers and surrenders the Certificate(s). In accordance with the terms of the Merger Agreement, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares) shall be cancelled and shall cease to exist, and shall be converted into the right to receive, without duplication, the Per Common Share Consideration; each share of Series A Convertible Preferred Stock issued and outstanding immediately prior to the Effective Time (other than any Dissenting Shares) shall be cancelled and shall cease to exist, and shall be converted into the right to receive the Per Share Series A Preferred Share Consideration; each share of Series C Convertible Preferred Stock issued and outstanding immediately prior to the Effective Time (other than any Dissenting Shares) shall be cancelled and shall cease to exist, and shall be converted into the right to receive the Per Share Series C Preferred Share Consideration; each share of Series D Convertible Preferred Stock issued and outstanding immediately prior to the Effective Time (other than any Dissenting Shares) shall be cancelled and shall cease to exist, and shall be converted into the right to receive the Per Share Series D Preferred Share Consideration (collectively the Per Common Share Consideration, Per Series A Preferred Share Consideration, Per Series C Preferred Share Consideration and Per Series D Preferred Share Consideration the “Share Consideration”). Capitalized terms used herein but not defined shall have the meaning set forth in the Merger Agreement.

The Board of Directors of the Company has approved the Merger Agreement, the Merger and the transactions contemplated thereby. Holders of (i) seventy-five percent of each class of the Company Preferred Stock outstanding and (ii) a majority of the outstanding Company Preferred Stock (voting on an “as-converted” basis) and the Company Common Stock, voting together as a single class, have adopted by written consent pursuant to the General Corporation Law of the State of Delaware (the “DGCL”) the Merger Agreement, thereby approving the Merger and the transactions contemplated by the Merger Agreement. Accordingly, the Merger Agreement has been adopted by all necessary action on the part of the Company and the stockholders of NSC (the “NSC Stockholders”). However, in order to receive your share of the amounts specified in Section 1.6 of the Merger Agreement, you will need to execute and deliver this Letter of Transmittal and Waiver of Appraisal Rights. For your information and convenience, a copy of the Merger Agreement is enclosed herewith.

Section 228 of the DGCL requires that prompt notice of the taking of corporate action, such as approving the Merger Agreement and the transactions contemplated thereby, including the Merger, without a meeting by less than unanimous written consent of stockholders shall be given to those stockholders who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting. This Letter of Transmittal constitutes the notice required to be given to the NSC Stockholders who did not execute the written consents approving the Merger Agreement and the transactions contemplated thereby, including the Merger, as required by Section 228 of the DGCL.

You as an NSC Stockholder have the right to seek appraisal of the fair value of your NSC Shares, as determined by the Delaware Court of Chancery, if the Merger is completed, and then only to the extent you comply with all requirements of Section 262 of the DGCL, the full text of which is attached as Exhibit B to this Letter of Transmittal. The appraisal amount you would receive could be more than, the same as or less than the amount you would be entitled to receive under the terms of the Merger Agreement. If you intend to exercise such appraisal rights then you must, among other things, submit a written demand for an appraisal to the Company within the time period specified by Section 262 of the DGCL. Your failure to follow exactly the procedures specified in Section 262 of the DGCL will result in the loss of your appraisal rights. This Letter of Transmittal is intended to serve as notice to you, as a NSC Stockholder, of your appraisal rights, as required by Section 262(d) of the DGCL.

Because of the complexity of Section 262 of the DGCL, you should consult with your advisors, including legal counsel, in connection with any demand for appraisal. Any demand for an appraisal should be sent to NSC at the following address:

National Surgical Care, Inc.
15950 North Dallas Parkway, Suite 775

This guarantee is a form of signature verification which can be obtained through an eligible financial institution such as a commercial bank, trust company, securities broker/dealer, credit union or savings institution participating in a Medallion program approved by the Securities Transfer Association.

•		Deficient Presentments: If you request a registration change that is not in proper form, the required documentation will be requested from you.

•		IRS Form W-9 or W-8: U.S. federal income tax law generally requires that if your shares are accepted for payment, you or your assignee (in either case, the “Payee”), must provide the Parent (the “Payor”) with the Payee’s correct TIN if you are a U.S. person (as defined in the instructions to the enclosed IRS Form W-9), which, in the case of a Payee who is an individual, is the Payee’s social security number. If the Payor is not provided with the correct TIN or an adequate basis for an exemption, the Payee may be subject to a $50 penalty imposed by the Internal Revenue Service (“IRS”) and backup withholding at a rate of 28 percent on the gross proceeds received pursuant to the Merger. Backup withholding is not an additional tax. Rather, the tax liability of a person subject to backup withholding will be reduced by the amount withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided the required information is timely furnished to the IRS.

		To prevent backup withholding, each Payee that is a U.S. person (as defined in the instructions to the enclosed IRS Form W-9) must provide such Payee’s correct TIN by completing the enclosed IRS Form W-9, certifying that (i) the TIN provided is correct, (ii) (a) the Payee is exempt from backup withholding, (b) the Payee has not been notified by the IRS that such Payee is subject to backup withholding as a result of a failure to report all interest or dividends, or (c) the IRS has notified the Payee that such Payee is no longer subject to backup withholding, and (iii) the Payee is a U.S. person (including a U.S. resident alien). If the Shares are held in more than one name or are not held in the name of the actual owner, consult the W-9 instructions for information on which TIN to report.

		Exempt Payees (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. To prevent possible erroneous backup withholding, an exempt Payee should check the “Exempt payee withholding” box on IRS Form W-9. See the W-9 Specific Instructions for additional instructions.

		In order for a nonresident alien or foreign entity to qualify as exempt, such person must submit an appropriate and properly completed IRS Form W-8, usually an IRS Form W-8BEN, signed under penalties of perjury attesting to such exempt status. An IRS W-8BEN and other Forms W-8 may be obtained from the IRS at its Internet website: www.irs.gov.

		TO PREVENT BACKUP WITHHOLDING ON PROCEEDS, EACH PAYEE SHOULD COMPLETE AND PROVIDE THE PARENT WITH THE ENCLOSED IRS FORM W-9 (FOR PAYEES THAT ARE U.S. PERSONS, INCLUDING U.S. RESIDENT ALIENS) OR AN APPROPRIATE IRS FORM W-8 (FOR PAYEES THAT ARE NOT U.S. PERSONS, AND IN MOST CASES THE ENCLOSED IRS FORM W-8BEN). CONSULT THE INSTRUCTIONS TO THE ENCLOSED IRS FORM W-9 FOR THE DEFINITION OF “U.S. PERSON.”

•		Returning Certificate(s): Return this Letter of Transmittal with the certificate(s) to the address below. The method of delivery is at your option and your risk, but it is recommended that documents be delivered via a registered method, insured for 2% of the value of your NSC Shares. Delivery of this instrument to an address other than as set forth below does not constitute valid delivery.

Annex A

Merger Agreement

Annex B

Section 262 of the Delaware General Corporation Law

§ 262. Appraisal rights.

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for

appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228 or § 253 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

3. Escrow Funds.

(a) At the Closing, the Acquiror shall deposit into an escrow account (the “Escrow Account”) an amount equal to (a) $15,000,000 (the “General Escrow Fund”) plus (b) $500,000 minus any adjustment to the Initial Merger Consideration Amount pursuant to subsection (vi) of the definition of Initial Merger Consideration Amount in the Merger Agreement (the “Working Capital Escrow Fund” together and with the General Escrow Fund, the “Escrow Funds”). The General Escrow Fund shall be available to pay any (i) payment to be made by the Acquiror to the Former Stakeholders pursuant to Section 1.15 and (ii) Acquiror Indemnifiable Losses. The Working Capital Escrow Fund shall be available to pay any payment to Acquiror by the Former Stakeholders pursuant to Section 1.14 of the Merger Agreement. For purposes of clarification, the General Escrow Fund and the Working Capital Escrow Fund shall be held in separate accounts, and the Escrow Agent shall keep a separate accounting of the balance of and the amounts disbursed from the General Escrow Fund and the Working Capital Escrow Fund.

(b) The Escrow Funds shall be held, invested and administered in accordance with the terms and provisions of this Escrow Agreement. The Escrow Funds shall not be subject to lien or attachment by any creditor of any party hereto and shall be used solely for the purposes set forth in this Escrow Agreement. Each of the parties hereto shall be entitled to their respective rights and shall perform their respective duties and obligations as set forth herein, in accordance with the terms hereof.

(c) The Escrow Agent shall provide written notice to each of the Acquiror and the Stockholders’ Representative of the balance of the Escrow Account attributable to the General Escrow Fund and the Working Capital Escrow Fund and the aggregate amount of any disbursements therefrom as of the end of each month within ten (10) Business Days of the last day of each month.

4. Disbursement of the Escrow Funds. The Escrow Agent shall release and disburse the Escrow Funds in accordance with the provisions of this Section 4 during the term of this Escrow Agreement.

(a) Subject to the terms of the Merger Agreement and the terms of this Escrow Agreement, the distribution of the Working Capital Escrow Fund shall be made by joint written instructions of the Acquiror and the Stockholders’ Representative, substantially in the form of Annex A hereto (a “Working Capital Joint Certificate”). Acquiror and Stockholders’ Representative shall submit a Working Capital Joint Certificate to the Escrow Agent within five (5) Business Days after the Final Determination Date. The Escrow Agent shall disburse the Working Capital Escrow Fund in accordance with the instructions in the Working Capital Joint Certificate within five (5) Business Days after receipt of the Working Capital Joint Certificate.

(b) Subject to the terms of the Merger Agreement and the terms of this Escrow Agreement, the distribution of the General Escrow Fund pursuant to Section 1.15 of the Merger Agreement shall be made by the joint written instructions of the Acquiror and the Stockholders’ Representative, substantially in the form of Annex B hereto (a “Joint Certificate”). Acquiror and Stockholders’ Representative shall submit a Joint Certificate to the Escrow Agent

within five (5) Business Days of Parent’s delivery to the Stockholders’ Representative of the Earnout Payment I Statement or Earnout Payment II Statement, as applicable, and if applicable, within five (5) Business Days after Earnout Payment I and Earnout Payment II, as applicable, are finally determined pursuant to Section 1.15 of the Merger Agreement. The Escrow Agent shall disburse funds from the General Escrow Fund in accordance with the instructions in the Joint Certificate within five (5) Business Days after receipt of the Joint Certificate. Any Reserve Amount (as defined below) withheld by the Escrow Agent from Earnout Payment I or Earnout Payment II shall be held by the Escrow Agent and disbursed in accordance with Section 4(e) below.

(c) Subject to the terms of the Merger Agreement and the terms of this Escrow Agreement, if the Acquiror has any claims for Acquiror Indemnifiable Losses, the Escrow Agent shall not disburse or release any funds from the Escrow Account in respect of such claims except in accordance with either: (x) the instructions set forth in a Joint Certificate or (y) the instructions set forth in a non-appealable, final judgment of a court of competent jurisdiction (a “Judgment”) accompanied by a certificate substantially in the form of Annex C hereto (a “Judgment Certificate”) executed by the Acquiror or the Stockholders’ Representative and stating that attached thereto is such a Judgment.

(d) At any time, the Stockholders’ Representative and the Acquiror may instruct the Escrow Agent to release Escrow Funds from the Escrow Account in accordance with instructions set forth in a Joint Certificate. In such event, the Escrow Agent shall within five (5) Business Days of receipt of the Joint Certificate disburse and release by wire transfer of immediately available funds to the account(s) identified in the Joint Certificate the amount set forth in the Joint Certificate.

(e) If at the time of payment of Earnout Payment I or Earnout Payment II as set forth in Section 4(b) above Acquiror has notified the Stockholders’ Representative of claims for indemnification pursuant to Section 8 of the Merger Agreement that remain pending or unresolved (each such matter, an “Unresolved Indemnification Matter”), an amount equal to Acquiror’s good faith estimate of the Losses relating to such Unresolved Indemnification Matters shall be retained in the Escrow Account and shall not be distributed pursuant to Section 4(b). Any such amount (the “Reserve Amount”) shall be retained in the Escrow Account and the portion of the Reserve Amount that relates to such Unresolved Indemnification Matter shall be distributed to Acquiror or the Stockholders’ Representative, as applicable, upon the final resolution of such Unresolved Indemnification Matter in accordance with the procedures specified in Section 4(c) pursuant to (A) the instructions set forth in a Joint Certificate or (B) the instructions set forth in a Judgment accompanied by a Judgment Certificate executed by the Acquiror or the Stockholders’ Representative. Any amounts remaining in the Reserve Amount following the resolution of all Unresolved Indemnification Matters and the payments described in this Section 4(e) shall be disbursed to the Stockholders’ Representative.

5. Investment of Escrow Funds.

(a) Pending disbursement and release of the Escrow Funds, the Escrow Agent shall invest the Escrow Funds in Permitted Investments as the Stockholders’ Representative and the Acquiror shall from time to time jointly instruct in writing. All interest and other income

earned on the Escrow Funds (net of any losses and expenses and the fees and expenses of the Escrow Agent as described in Section 7) will be retained by the Escrow Agent and added to and become a part of the Escrow Funds; provided, that on a quarterly basis the Escrow Agent shall pay to the Acquiror an amount equal to 40% of the interest and other income earned on the Escrow Funds during the preceding quarter and shall provide notice to the Stockholders’ Representative of the amount and date of such payment. For purposes of this Escrow Agreement, “Permitted Investments” shall mean: (i) direct obligations of the United States government having maturities of 30 days or less; (ii) commercial paper and repurchase agreements having daily liquidity with United States banks, which may include the Escrow Agent, whose short-term debt ratings are not less than A-1/P-1, non-enhanced municipal bonds (with a rating of AAA by Moody’s Investor Services or Standard and Poor’s); (iii) money market deposit accounts, time deposits, money market funds that invest solely in direct obligations of the United States government or agencies, and investment grade corporate bonds; and (iv) such other instruments and securities as may be mutually agreed upon in writing by the Stockholders’ Representative and the Acquiror. Except as otherwise provided in this Section 5, the Escrow Agent shall have no duty, responsibility or obligation to invest any funds or cash held in the Escrow Account other than in accordance with this Section 5. The Escrow Agent shall have no liability or responsibility for any investment losses with respect to Permitted Investments, including without limitation, any market loss on any Permitted Investment liquidated (whether at or prior to maturity) in order to make a payment required under this Escrow Agreement.

(b) In the event that the Escrow Agent shall not have received a direction for investment for any moneys in the Escrow Funds in accordance with the terms of this Agreement, the Escrow Agent may invest the Escrow Funds from time to time in a Regions Bank money market deposit account as more fully explained and as set forth on Annex D hereto. For purposes of clarification, the Acquiror and the Stockholders’ Representative, in the absence of specific instructions issued by such parties, authorize the Escrow Agent to make the foregoing investment.

(c) As and when any amount is needed for payments under this Escrow Agreement, the Escrow Agent shall cause a sufficient amount of the Permitted Investments to be converted into cash.

(d) The Acquiror is intended to be, and shall be treated as, the owner for income tax purposes of the Escrow Funds (and any other corpus and income held in the Escrow Account) and of all of the items of income, deductions and credits attributable to the Escrow Funds (and attributable to all of such other corpus and interest). The provisions of this Escrow Agreement shall be construed and interpreted accordingly, and all parties hereto shall file tax returns and statements consistent with such treatment, it being understood that the Escrow Agent shall not be responsible for any tax reporting responsibilities of the Former Stakeholders, the Stockholders’ Representative or the Acquiror.

6. Agreement with Escrow Agent. This Escrow Agreement sets forth exclusively the duties of the Escrow Agent with respect to any and all matters pertinent hereto and no implied duties or obligations shall be read into this Escrow Agreement against the Escrow Agent. In furtherance and not in limitation of the foregoing:

(a) the Escrow Agent shall be fully protected and shall incur no liability (other than as a result of the Escrow Agent’s gross negligence, material breach of the Escrow Agreement or willful misconduct), in relying upon and acting upon any written certification, notice, instruction, direction, request, waiver, consent, receipt, communication, paper or other document that the Escrow Agent believes to be genuine and duly executed and delivered in accordance with this Escrow Agreement;

(b) the Escrow Agent shall not be liable for any error of judgment, or for any action taken, suffered or omitted by it, or for any mistake in fact or law, or for anything that it may do or refrain from doing in connection herewith; provided, however, that notwithstanding any other provision in this Escrow Agreement, (x) the Escrow Agent shall be liable or responsible for its willful misconduct, gross negligence or material breach of this Escrow Agreement; and (y) in no event shall the Escrow Agent be liable for special, punitive, indirect, consequential or incidental loss or damage of any kind whatsoever to any person (including, but not limited to, lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage;

(c) the Escrow Agent may seek the advice of legal counsel selected with reasonable care in the event of any conflicting or inconsistent claims or demands being made in connection with the subject matter of this Escrow Agreement or any dispute or question as to the construction of any of the provisions of this Escrow Agreement or its duties hereunder, and it shall incur no liability and shall be fully protected in respect of any action taken, omitted or suffered by it in good faith in accordance with the written advice of such counsel;

(d) in the event that the Escrow Agent shall in any instance, after seeking the advice of legal counsel pursuant to paragraph (c) of this Section 6, in good faith be uncertain as to its duties or rights hereunder or reasonably believe any ambiguity or uncertainty exists hereunder or in any notice, instruction, direction, request or other communication, paper or document received by the Escrow Agent hereunder, it shall be entitled to refrain from taking any action to which such ambiguity or uncertainty relates and shall be fully protected and shall not be liable in any way to the Former Stakeholders, the Acquiror or the Stockholders’ Representative for refraining from taking such action, and its sole obligation, in addition to those of its duties hereunder as to which there is no such ambiguity or uncertainty and which are not impacted by such ambiguity or uncertainty, shall be to keep safe all property held in the Escrow Funds until it shall be directed otherwise in writing by the Acquiror and the Stockholders’ Representative or by a final, nonappealable order of a court of competent jurisdiction; provided, however, in the event that the Escrow Agent has not received such written direction or court order within 180 calendar days after requesting the same, it shall have the right to interplead the Acquiror and the Stockholders’ Representative in any court of competent jurisdiction and request that such court determine its rights and duties hereunder;

(e) nothing in this Escrow Agreement shall be deemed to impose upon the Escrow Agent any duty to qualify to do business in any jurisdiction other than the State of Tennessee and the Escrow Agent shall not be responsible for and shall not be under a duty to examine into or pass upon the validity, binding effect, execution or sufficiency of this Escrow Agreement or of any agreement amendatory or supplemental hereto; and

(f) the Escrow Agent does not have and will not have any interest in the Escrow Funds but is serving only as escrow holder and has only possession thereof.

7. Fees and Expenses; Indemnity.

(a) The fees of the Escrow Agent as described on Annex E and the reasonable costs and expenses actually incurred by the Escrow Agent for its services in respect of the Escrow Funds hereunder (collectively, the “Escrow Agent Fees and Expenses”) shall be paid fifty percent (50%) out of the Escrow Funds and fifty percent (50%) by Acquiror. The Escrow Agent Fees and Expenses shall be deducted fifty percent (50%) from the Escrow Funds and fifty percent (50%) paid by Acquiror fifteen (15) Business Days following delivery of an invoice therefore to the Acquiror and the Stockholders’ Representative unless the Acquiror or the Stockholders’ Representative objects in writing to the Escrow Agent Fees and Expenses within such fifteen (15) Business Day period.

(b) The Stockholders’ Representative (solely on behalf of the Former Stakeholders and in its capacity as the Stockholders’ Representative, not in its individual capacity) and the Acquiror, jointly and severally, hereby agree to indemnify Escrow Agent for, and to hold it harmless against, any loss, liability or reasonable expense (including reasonable attorneys’ fees and expenses) actually incurred by the Escrow Agent, arising out of or in connection with its entering into this Escrow Agreement and carrying out its duties hereunder, including the reasonable costs and expenses of defending itself from any claim or liability; provided, however, that the Escrow Agent shall not be entitled to indemnification hereunder for losses, liabilities and expenses which arise out of the willful misconduct, gross negligence or material breach of this Escrow Agreement by the Escrow Agent. The Stockholders’ Representative and the Acquiror agree that any payments made to the Escrow Agent under the indemnification obligation in the immediately preceding sentence, whether made by the Stockholders’ Representative (solely on behalf of the Former Stakeholders and in its capacity as the Stockholders’ Representative, not in its individual capacity), on the one hand, or the Acquiror, on the other hand, or both, are to be borne in equal amounts by the Stockholders’ Representative (solely on behalf of the Former Stakeholders and in its capacity as the Stockholders’ Representative, not in its individual capacity), on the one hand, or the Acquiror, on the other hand, and hereby grant to each other a right of contribution to effect the same. Notwithstanding the foregoing, nothing in this Escrow Agreement shall derogate from the indemnification rights or obligations of any party to the Merger Agreement. The agreements contained in the three immediately preceding sentences shall survive despite any termination of this Escrow Agreement or the resignation or removal of the Escrow Agent.

8. Resignation and Removal of the Escrow Agent. The Escrow Agent, and any successor Escrow Agent, may resign at any time as the Escrow Agent hereunder by giving at least thirty (30) days’ written notice to the Stockholders’ Representative and the Acquiror; provided, however, that the Escrow Agent’s resignation shall not be effective unless and until a successor Escrow Agent is appointed and the Escrow Agent delivers the Escrow Funds to such successor. Upon such resignation, the resigning Escrow Agent shall be absolved from any and all liability in connection with the exercise of its powers and duties as Escrow Agent hereunder except for liability arising in connection with its gross negligence, material breach of the Escrow Agreement or willful misconduct. Upon their receipt of notice of resignation from the Escrow

Agent, the Stockholders’ Representative and the Acquiror shall use reasonable efforts to designate a successor Escrow Agent. In the event the Stockholders’ Representative and the Acquiror do not agree upon a successor Escrow Agent within thirty (30) days after the receipt of such notice, the Escrow Agent so resigning may petition any court of competent jurisdiction for the appointment of a successor Escrow Agent located within the territorial United States and with capital and surplus comparable to the capital and surplus of the Escrow Agent or other appropriate relief and any such resulting appointment shall be binding upon all parties hereto. By mutual written agreement, the Stockholders’ Representative and the Acquiror shall have the right to terminate their appointment of the Escrow Agent, or successor Escrow Agent, as Escrow Agent. The Escrow Agent or successor Escrow Agent shall continue to act as Escrow Agent until a successor is appointed and qualified to act as Escrow Agent.
