Section 3.8 Paying Agent; Exchange of Certificates; Treatment of Options; Withholdings.

(a) Paying Agent. US Bank N.A. shall act as paying agent (the “Paying Agent”) in effecting the exchange of cash for certificates which, immediately prior to the Closing, represented shares of Liberty Stock and which are converted into the right to payment pursuant to Section 3.1. At the Effective Time, each Signing Stockholder shall surrender to the Purchaser all of such Signing Stockholder’s certificates of Liberty Stock, together with a duly executed Letter of Transmittal, representing the number of shares of Liberty Stock held by such Signing Stockholder. At the Closing, the Purchaser shall instruct the Paying Agent to pay each Signing Stockholder who has surrendered such Signing Stockholder’s certificates of Liberty Stock, together with a duly executed Letter of Transmittal, the amount of cash to which such Signing Stockholder is entitled under Section 3.1, which amounts shall be determined in accordance with the Closing Statement and the terms herein. Purchaser shall instruct the Paying Agent to pay each other Stockholder that surrenders such Stockholder’s certificates of Liberty Stock, together with a duly executed Letter of Transmittal, the amount of cash to which such Stockholder is entitled under Section 3.1, which amounts shall be consistent with the Closing Statement. In accordance with Section 3.8(b), all cash payments shall be made by wire transfer of immediately available funds (with the Purchaser being responsible for all wire fees). Surrendered certificates shall forthwith be canceled. Until so surrendered and exchanged, each such certificate shall represent solely the right to receive the portion of the Merger Consideration into which the shares it theretofore represented shall have been converted pursuant to Section 3.1, and the Purchaser shall not be required to instruct the Paying Agent to pay the holder thereof the cash to which such Stockholder would otherwise have been entitled.

(b) Exchange of Certificates. Prior to the Effective Time, the Company shall send a Letter of Transmittal to the Stockholders specifying that delivery of stock certificates may be made prior to the Closing Date to the Company for delivery to the Purchaser before the Effective Time. All cash paid upon conversion of Liberty Stock in accordance with the terms of this ARTICLE III shall be deemed to have been paid in full

satisfaction of all rights pertaining to Liberty Stock, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Liberty Stock which were outstanding immediately prior to the Effective Time. At any time that is more than one (1) year after the Effective Time, the Purchaser may cause the Paying Agent to pay over to the Surviving Corporation any portion of the Closing Stockholder Consideration (including any earnings thereon) that had been delivered to the Paying Agent but has not been disbursed as of such date. Thereafter, all former holders of Liberty Stock shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat and other similar laws) as general creditors thereof with respect to the cash payable upon surrender of their stock certificates pursuant to this Agreement and the Paying Agent shall have no further obligation with respect thereto. If any stock certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such stock certificate to be lost, stolen or destroyed and, if required by the Purchaser, the posting by such Person of a bond in such reasonable amount as the Purchaser may direct as indemnity against any claim that may be made against it with respect to such stock certificate, the Purchaser will deliver in exchange for such lost, stolen or destroyed stock certificate the amount of cash applicable with respect to the shares of capital stock formerly represented thereby in accordance with Section 3.1.

(i) Immediately prior to the Closing, each Option granted under the Stock Option Plan whether vested or unvested, that is outstanding immediately prior to the Closing shall become 100% vested. At the Closing, each Option granted under the Stock Option Plan that was outstanding and unexercised as of immediately prior to the Closing shall have all remaining rights thereunder cancelled, and, in exchange therefor, the Surviving Corporation shall pay to the former holder of any such cancelled Option (A) on the Closing Date an amount in cash (without interest, and subject to deduction for any required withholding Tax) equal to the Per Option Amount for such Option multiplied by the number of shares of Non-Voting Common Stock subject to such Option and (B) after completion of the Final Closing Statement, the right to receive, if applicable, the Allocable Per Share Working Capital Surplus and the Allocable Per Share Closing Cash Surplus (subject in each case to deduction for any withholding Taxes).

(ii) Prior to the Closing, the Company shall adopt such resolutions and amendments to the Stock Option Plan documents and take or cause to be taken all action as may be reasonably required to effectuate the provisions of this Section 3.8(c) and to terminate the Stock Option Plan conditioned and effective upon the consummation of the Merger.

(d) Withholdings. The Purchaser, the Company, the Paying Agent, the Escrow Agent, the Surviving Corporation and each other applicable withholding agent (as appropriate) shall be entitled to deduct and withhold from consideration otherwise payable pursuant to this Agreement or the Escrow Agreement to any Holder such

amounts as are required to be deducted and withheld with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld, (A) such withheld amounts shall be treated for all purposes of this Agreement and the Escrow Agreement as having been paid to the Holder in respect of which such deduction and withholding was made, and (B) the Purchaser, the Company, the Surviving Corporation, the Paying Agent or other applicable withholding agent shall provide to such Holder written notice of the amounts so deducted or withheld.

Section 3.9 Working Capital Adjustment.

(a) No later than ninety (90) days following the Closing Date, the Purchaser shall prepare and deliver to the Stockholder Representative the draft closing statement of the Company as of the Closing Date (the “Revised Closing Statement”), prepared in accordance with GAAP and in a manner consistent with the guidelines set forth on Exhibit 1.1(a), which shall include a calculation of each of (i) the Closing Date Working Capital (Liberty) and the Closing Date Working Capital (Renal), (ii) the Closing Date Target Working Capital (Liberty) and the Closing Date Target Working Capital (Renal), (iii) the Positive Target Adjustment, if any, or the Negative Target Adjustment, if any, (iv) the Working Capital Surplus, if any, (v) the Working Capital Deficit, if any, (vi) the Closing Cash, (vii) the Closing Cash Surplus, if any, (viii) the Closing Cash Deficit, if any, and (ix) the Company Negative Working Capital (if any).

(b) The Stockholder Representative shall have sixty (60) days following receipt of the Revised Closing Statement during which to notify the Purchaser of any dispute of any item contained in the Revised Closing Statement, which notice shall set forth in reasonable detail the basis for such dispute. At any time within such sixty (60) day period, the Stockholder Representative shall be entitled to agree with any or all of the items set forth in the Revised Closing Statement. During such sixty (60) day period, the Purchaser and the Company shall provide the Stockholder Representative with reasonable access during normal business hours to Company employees and advisors and such books and records of the Company as may be reasonably requested by them to verify the information contained in the Revised Closing Statement and the calculations therein.

(c) If the Stockholder Representative does not notify the Purchaser of any such dispute within such sixty (60) day period, or notifies the Purchaser of its agreement with the adjustments in the Revised Closing Statement prior to the expiration of the sixty (60) day period, the Revised Closing Statement prepared by the Purchaser shall be deemed to be the “Final Closing Statement.”

(d) If the Stockholder Representative notifies the Purchaser of any such dispute within such sixty (60) day period, the Final Closing Statement shall be resolved as follows:

(i) The Purchaser and the Stockholder Representative shall cooperate in good faith to resolve any such dispute as promptly as possible.

(ii) In the event the Purchaser and the Stockholder Representative are unable to resolve any such dispute within thirty (30) days (or such longer period as the Purchaser and the Stockholder Representative shall mutually agree in writing) of notice of such dispute, such dispute and each Party’s work papers related thereto shall be submitted to, and all issues having a bearing on such dispute shall be resolved by (x) PricewaterhouseCoopers LLP or (y) if PricewaterhouseCoopers LLP is unwilling to serve, then such other independent national accounting firm, that is selected by the American Arbitration Association at the request of the first of the Parties to move (such independent accounting firm being referred to herein as the “Arbitrator”). Absent fraud or manifest error, the Arbitrator’s resolution shall be final and binding on the Parties. The Arbitrator’s resolution shall be determined in accordance with GAAP and in a manner consistent with the guidelines set forth on Exhibit 1.1(a), and shall be based solely on presentations of the Purchaser and the Stockholder Representative (and not on the Arbitrator’s independent review) and limited to only those matters in dispute. In resolving any disputed item, the Arbitrator may not assign a value to any item greater than the greatest value for such items claimed by either the Purchaser or the Stockholder Representative or less than the smallest value for such items claimed by either the Purchaser or the Stockholder Representative (in either case, as may have been modified pursuant to Section 3.9(d)(i)). The Arbitrator’s role and authority shall be limited to deciding disputes hereunder; disputes regarding the proper scope of the arbitration or the scope of the Arbitrator’s authority shall be determined by a court of competent jurisdiction consistent with Section 11.6 below. The Purchaser and the Stockholder Representative shall use commercially reasonable efforts to cooperate with the Arbitrator and to cause the Arbitrator to complete its work within thirty (30) days following its engagement. The fees, costs and expenses of the Arbitrator shall be apportioned by the Arbitrator among the Purchaser and the Stockholder Representative based upon the relevant extent to which the positions of the Purchaser and the Stockholder Representative are upheld by the Arbitrator.

applicable Governmental Entities in the State of Illinois, New Jersey or Rhode Island to the transactions contemplated hereby. In addition, if the Closing has been delayed past such date solely because the Parties cannot agree, in good faith, upon the structure of the Spinoff (as is more fully addressed in Section 7.13 below), then such amount shall not be payable, provided, however, that if the structuring is agreed upon subsequent to such date and the Purchaser then fails to implement the Spinoff and effectuate the Closing within three Business Days thereof (assuming all other conditions to the Closing have been satisfied), then such amount shall become payable on the next Business Day.

To the Knowledge of the Company, there are no improvements made or contemplated to be made by any public or private authority, the costs of which are to be assessed as special taxes or charges against any of the Leased Real Property.

(g) Except as set forth in Section 4.6(g) of the Company Disclosure Schedule, since the time the Company acquired or developed the applicable Leased Real Property, none of the Leased Real Property or improvements thereon undertaken by the Company or any of its Subsidiaries, or the condition or use thereof by the Company or any of its Subsidiaries, including the operation of the business, materially contravenes or violates any building, zoning, fire safety, seismic, design, conservation, parking, architectural barriers to the handicapped, occupational safety and health or other applicable Law, or any restrictive covenant (whether or not permitted on the basis of prior nonconforming use, waiver or variance), including the Americans with Disabilities Act of 1990. Neither the Company nor any Subsidiary has received any written notice of any material violation of any applicable zoning ordinance or other Law relating to the operation of the Leased Real Property.

and nature of such access (which such notice and coordination should be to and with the Company’s Chief Executive Officer, Chief Financial Officer or such other person as the Company may designate in writing from time to time), provide the Purchaser and its Agents reasonable access, during normal business hours, without interfering with the operation of the business of the Company or its Subsidiaries, to the premises, employees (including executive officers), properties (including, for the purposes of conducting non-subsurface environmental assessments), contracts, books, records and other information (including Tax Returns filed and those in preparation) of the Company and its Subsidiaries and shall cause the Company’s and its Subsidiaries’ officers to furnish to and discuss with the Purchaser and its Agents, such financial, business, technical and operating data and other information pertaining to the Company and its Subsidiaries as Purchaser may reasonably request, subject to compliance with applicable Law, including the HSR Act. Notwithstanding anything to the contrary herein, in the event that the Purchaser and its Agents desire to initiate contact or communicate with any of the Special Affiliates, any of the employees (other than [*]), vendors or payors of the Company or its Subsidiaries, or with any other Person with a material business relationship with the Company or any of the Subsidiaries, and such contact or communication directly or indirectly relates to or is in connection with the Merger or the transactions contemplated hereby, the Purchaser shall first consult with and obtain the written consent of the Company.

(h) the formation of any Subsidiary or joint venture relationship not in existence on the date hereof and the entry into of any Contract with any minority owners of any new Subsidiary or joint venture.

Section 7.4 Exclusivity. From and after the execution of this Agreement until the Closing or the earlier termination of this Agreement pursuant to and in accordance with ARTICLE IX, the Company and its Subsidiaries and each of the Signing Stockholders shall, and shall cause their respective Affiliates and their and their respective Affiliates’ Agents to cease and terminate any existing activities, discussions or negotiations with any parties conducted heretofore with respect to, and not to initiate, solicit or encourage (including by way of furnishing non-public information or assistance), or enter into negotiations or discussions of any type, directly or indirectly, or enter into a confidentiality agreement, letter of intent or purchase agreement, merger agreement or other similar agreement with any Person other than the Purchaser with respect to a sale of all or any material portion of the assets of the Company or any of its Subsidiaries, or a merger, consolidation, business combination, sale of all or any portion of the capital stock of the Company or any of its Subsidiaries, or the liquidation or similar extraordinary transaction with respect to the Company or any of its Subsidiaries; provided, however, that the restrictions set forth in this Section 7.4 shall not apply to any Permitted Minority Sales.

Each Signing Stockholder shall notify Purchaser orally (within two (2) Business Days) and in writing (as promptly as practicable) of all

relevant terms of any written proposal by a third party to do any of the foregoing that such Signing Stockholder receives or, to its knowledge, any of its Affiliates receives.

Section 7.7 Tax Matters.

(a) Tax Returns. The Company or (following the Closing) the Stockholder Representative shall prepare and file, or cause to be prepared and filed, all Tax Returns (including such Tax Returns filed pursuant to any valid extension of time to file and any amendments thereto) required to be filed by the Company or its Subsidiaries with respect to any Pre-Closing Period (“Pre-Closing Period Tax Returns”), and the Stockholders shall, subject to Section 7.7(j), be liable for all Taxes with respect to such Pre-Closing Period Tax Returns. Pre-Closing Period Tax Returns shall be prepared on a basis consistent with Section 7.7(j) and the Tax Returns previously filed by the Company and its Subsidiaries, unless otherwise required by applicable Tax Law. The Company or (following the Closing) the Stockholder Representative shall provide a copy of each such

Pre-Closing Period Tax Return to the Purchaser for the Purchaser’s review at least fifteen (15) days before such Tax Return is filed by the Company and shall consider in good faith any comments provided by the Purchaser. The Purchaser shall, at the Purchaser’s expense, prepare and file all Tax Returns required to be filed by the Company or its Subsidiaries for all taxable periods beginning after the Closing Date (“Post-Closing Period Tax Returns”), and the Purchaser shall pay, or cause to be paid, all Taxes with respect to such Post-Closing Period Tax Returns.

(b) Straddle Period Tax Returns. The Purchaser shall, at the Purchaser’s expense, prepare and file, or cause to be prepared and filed, any Tax Returns required to be filed by the Company or its Subsidiaries for any taxable periods which include (but do not end on) the Closing Date (“Straddle Periods”) (such Tax Returns, “Straddle Period Tax Returns”) and the Purchaser shall pay, or cause to be paid, all Taxes with respect to such Straddle Period Tax Returns, subject to the Stockholders’ obligation for the Taxes of such Straddle Period attributable to the portion of the Straddle Period ending on the Closing Date, as determined in accordance with Section 7.7(c) and subject to Section 7.7(j). Such Straddle Period Tax Returns shall be prepared on a basis consistent with Section 7.7(j) and the Tax Returns previously filed by the Company and its Subsidiaries, unless otherwise required by applicable Tax Law. The Purchaser shall provide a copy of each Straddle Period Tax Return together with copies of any relevant supporting schedules, work papers and other documentation that are reasonably requested by the Stockholder Representative, and a sufficiently detailed statement certifying the amount of any Taxes of a Straddle Period attributable to the portion of the Straddle Period ending on the Closing Date (the “Pre-Closing Taxes”) shown on such Straddle Period Tax Returns, if any, that may be chargeable to the Stockholders (the “Tax Statement”) to the Stockholder Representative for review and comment at least fifteen (15) days before such Straddle Period Tax Return is filed (taking into account any valid extensions) and shall consider in good faith any comments provided by the Stockholder Representative. The Purchaser and the Stockholder Representative agree to consult and resolve in good faith any objections from the Stockholder Representative with respect to the Straddle Period Tax Returns or Pre-Closing Taxes. However, if the Purchaser and the Stockholder Representative cannot resolve any such objections, the matter shall be referred to the Arbitrator for prompt resolution.

(c) Calculation of Taxes for Straddle Period Tax Returns. Subject to Section 7.7(j), Pre-Closing Taxes for Straddle Period Tax Returns shall be calculated as though the taxable period of the Company and its Subsidiaries terminated as of the Closing Date (and, for such purpose, the Taxable period of any partnership or other pass-through in which the Company or any Subsidiary holds an interest will be deemed to terminate at such time); provided, however, that (i) in the case of a Tax not based on income, activities, events, the level of any item, receipts, proceeds, profits or similar items, Pre-Closing Taxes shall be equal to the amount of Tax for the entire Straddle Period, multiplied by a fraction the numerator of which is the total number of days from the beginning of the Straddle Period through the Closing Date and the denominator of which is the total number of days in the Straddle Period and (ii) any item determined on an annual or periodic basis (such as deductions for depreciation or real estate Taxes) shall be apportioned on a daily basis. All Straddle Period Tax Returns shall be prepared, and all

determinations necessary to give effect to the foregoing allocations shall be made, in a manner consistent with Section 7.7(j) and the prior practice of the Company and its Subsidiaries.

(d) Amendments, Modifications, Refunds, etc.

(i) After the Closing Date, the Purchaser or any Affiliate, to the extent permitted by Tax Law, shall have the right to amend, modify or otherwise change (a “Tax Amendment”) all Tax Returns of the Company or its Subsidiaries for all Tax periods; provided, however, that the Stockholders shall not be liable for any increase in their respective Tax Liability (whether under this Agreement or otherwise) for any period resulting, directly or indirectly, from any such Tax Amendment to any Tax Returns.

(ii) To the extent any determination of Tax Liability of the Company, whether as the result of an audit or examination, a claim for refund, the filing of an amended return or otherwise results in any refund, credit or other reduction of Taxes (“Tax Refunds”) attributable to any period which ends on or before the Closing Date or any portion thereof, any such Tax Refund shall be credited to the Stockholders, and Purchaser shall promptly pay any such Tax Refunds and the interest actually received thereon (net of any Taxes payable with respect to such Tax Refunds or interest taking into account the deductibility, if any, of such Taxes payable) to the Stockholder Representative upon receipt thereof by Purchaser. Upon the Stockholder Representative’s reasonable determination of the availability of a Tax Refund attributable to any period (or portion thereof) which ends on or before the Closing Date, the Stockholder Representative may request that the Purchaser, the Company or any of its Affiliates file or claim a Tax Refund or file an amended Tax Return and conduct the prosecution of such claims of Tax Refund in good faith. The Purchaser shall comply with the Stockholder Representative’s request to seek a Tax Refund or file an amended Tax Return. The Stockholders shall reimburse the Purchaser, the Company or any of its Subsidiaries for reasonable out-of-pocket costs associated with any claim for Tax Refund or any amended Tax Return filed at the request of the Stockholders.

(e) Cooperation. The Stockholder Representative, the Company and its Subsidiaries and the Purchaser shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the preparation and filing of Tax Returns pursuant to this Section 7.7, any Tax Proceeding (as defined below) and the review of any current or potential Tax Refund. Such cooperation shall include signing any Tax Returns, amended Tax Returns, claims or other documents necessary to settle any Tax Proceeding, the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such Tax Proceeding or any Tax Refund and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereby.

(f) Tax Proceedings.

(i) This Section 7.7(f) and not Section 10.3 shall govern with respect to Tax Proceedings (as defined below). After the Closing, the Purchaser shall promptly notify the Stockholder Representative in writing of any proposed assessment or the commencement of any Tax audit or administrative or judicial proceeding or of any demand or claim on the Purchaser or the Company or its Subsidiaries (“Tax Proceeding”) which, if relating to a Pre-Closing Period (or a Straddle Period Tax Return) or if determined adversely to the taxpayer or after the lapse of time, could result in an indemnification obligation of the Stockholders under this Agreement. After the Closing, the Stockholder Representative shall promptly notify the Purchaser in writing of any Tax Proceeding relating to the Company or its Subsidiaries, notice of which is received by the Stockholders or the Stockholder Representative. Notices required to be given by or to the Purchaser or the Stockholder Representative shall contain factual information (to the extent known to the Stockholders, Stockholder Representative, the Purchaser or the Company or its Subsidiaries, as the case may be) describing the asserted Tax Liability in reasonable detail and shall include copies of any notice or other document received from any Governmental Entity in respect of any such asserted Tax Liability.

(ii) In the case of a Tax Proceeding that relates solely to any Pre-Closing Period, but excluding any Straddle Periods, the Stockholder Representative shall have the right to direct and control the conduct of such Tax Proceeding, provided the Purchaser shall have the right to participate (at the Purchaser’s own expense) in any such Tax Proceeding. The Purchaser’s right to participate shall include, but shall not be limited to, the right to receive copies of all correspondence from any Governmental Entity relating to such Tax Proceeding, attend meetings and review and comment on submissions relating to any Tax Proceeding, and Stockholder Representative shall consider in good faith any comments provided by the Purchaser. The Stockholder Representative may, on behalf of the Stockholders, elect to waive the Stockholder Representative’s right under this Section 7.7(f) to direct and control any Pre-Closing Period Tax Proceeding. Unless the Stockholder Representative notifies the Purchaser of its intent to direct and control any such Pre-Closing Period Tax Proceeding within fifteen (15) days of receipt by the Stockholder Representative of the notice of any such Tax Proceeding, the Stockholder Representative shall be deemed to have waived its right to direct and control such Pre-Closing Period Tax Proceeding. In the event that the Stockholder Representative waives its right to direct and control such Pre-Closing Period Tax Proceeding, Purchaser shall assume control of such Tax Proceeding and the Stockholder Representative shall be liable to the Purchaser for all costs and expenses of such Tax Proceeding. Upon such a waiver, the Stockholder Representative shall have the right to participate (at the Stockholder Representative’s own expense) in any such Tax Proceeding. The Stockholder Representative’s right to participate shall include, but shall not be limited to, the right to receive copies of all correspondence from any Governmental Entity relating to such Tax Proceeding, attend meetings and review and comment on submissions relating to any Tax Proceeding, and the Purchaser shall consider in good faith any comments provided by the Stockholder

Representative; provided, however, that neither the Purchaser nor the Company or its Subsidiaries may settle or compromise any Tax Proceeding for any Pre-Closing Period without prior written consent of the Stockholder Representative; provided further, however, that such consent to settlement or compromise shall not be unreasonably withheld.

(iii) In the case of a Tax Proceeding that relates to any Straddle Periods, the Purchaser shall have the right to control the conduct of such Tax Proceeding, provided the Stockholder Representative shall have the right to participate (at the Stockholder Representative’s own expense) in any such Tax Proceeding involving any asserted Tax Liability for such Straddle Period with respect to which payment may be sought from the Stockholders pursuant to this Agreement. The Stockholder Representative’s right to participate shall include, but shall not be limited to, the right to receive copies of all correspondence from any Governmental Entity relating to such Tax Proceeding, attend meetings and review and comment on submissions relating to any Tax Proceeding, and the Purchaser shall consider in good faith any comments provided by Stockholder Representative. Neither the Purchaser nor the Company or its Subsidiaries may settle or compromise any Tax Proceeding for any Straddle Period that would result in an indemnification obligation of the Stockholders for Taxes under this Agreement without prior written consent of the Stockholder Representative; provided, however, that consent to settlement or compromise shall not be unreasonably withheld or delayed.

(g) Transfer Taxes. Notwithstanding anything to the contrary in this Agreement, (i) except as described in clause (ii) of this sentence, any sales, use, real estate transfer, stock transfer or similar transfer Tax (“Transfer Taxes”) payable in connection with the transactions contemplated by this Agreement shall be borne by the Party liable for such Transfer Taxes pursuant to applicable law and (ii) any Transfer Taxes incurred in connection with a Spinoff shall be borne by [*], any Transfer Taxes incurred in connection with a Dialysis Center Divestiture shall be borne by the [*] and any Transfer Taxes incurred in connection with a Retained Dialysis Center Distribution shall be borne by [*]. Each Party shall duly and timely prepare and file any Tax Return relating to Transfer Taxes that they are required by Law to file.

(h) Actions With Respect to Taxes. Without the prior written consent of the Purchaser, which consent shall not be unreasonably withheld or delayed, the Company and its Subsidiaries shall not change any Tax election or entity classification status of the Company or any of its Subsidiaries, change an annual Tax accounting period, change any Tax accounting method, file any amended Tax Return, enter into any closing agreement, settle any Tax claim or assessment, surrender any right to claim a refund of Taxes, consent to any extension or waiver of the limitation period applicable to any Tax claim or assessment (other than pursuant to extensions of time to file Tax Returns obtained in the Ordinary Course), if such election, adoption, change, amendment, agreement, settlement, surrender or consent would have the effect of increasing the Tax liability of the Company

or its Subsidiaries for any period or decreasing any Tax attribute of the Company or its Subsidiaries that would exist on the Closing Date.

(i) Tax Sharing Agreements. All tax sharing agreements or similar agreements (other than commercial agreements not primarily relating to Taxes) with respect to or involving the Company or its Subsidiaries, except for such agreements and arrangements solely with respect to or involving the Company and or its Subsidiaries, shall be terminated as of the Closing Date and, after the Closing Date, no such party shall be bound thereby or have any Liability thereunder.

(j) Certain Tax Matters. Notwithstanding anything to the contrary in this Agreement, the Stockholders shall have no Liability or other obligation with respect to Taxes of the Company or any of its Subsidiaries attributable (determined on a “with or without” basis) to the Divestiture/Spinoff Transactions. Further, (i) any Liability of the Stockholders hereunder with respect to Taxes and the right of the Stockholders to any Tax Refunds (including pursuant to clause (ii)) shall be based on the Calculation Principles and (ii) to the extent that a Tax Refund for a Pre-Closing Period (or the portion of any Straddle Period through the end of the Closing Date) would be available (including by way of an amended Tax Return, a carryback claim or otherwise) if the Divestiture/Spinoff Transactions did not occur, the Purchaser shall promptly pay the amount of such Tax Refund to the Stockholder Representative (or its designee) upon determination that such Tax Refund would be available. Purchaser shall provide the Stockholder Representative with information and cooperation necessary to make such determination. With respect to the sale, distribution or other disposition of (x) the Retained Dialysis Centers and Divested Dialysis Centers, the Tax Returns of the Company and its Subsidiaries shall report an amount realized based on the purchase price for the Retained Dialysis Centers and Divested Dialysis Centers and (y) the Spinoff Subsidiaries, the Tax Returns of the Company and its Subsidiaries shall report an amount realized treating the gross fair market value of the assets acquired in the Spinoff as equal to the Spinoff Amount with respect to the relevant Spinoff Subsidiary. The Stockholders shall have no Liability or other obligation under this Agreement if a Tax Proceeding determines that the amount realized with respect thereto should be treated as a higher amount. The Pre-Closing Benefits shall not be reported in a post-Closing Tax period and shall be reported in Pre-Closing Periods (or the portion of any Straddle Period ending on the Closing Date). Notwithstanding anything to the contrary in this Agreement, any items of income or gain and Liability for Taxes attributable to actions taken by the Company or its Affiliates on the Closing Date but after the Closing shall be treated as occurring in a post-Closing Tax period.

(k) No Section 338 Election; Carrybacks. No election under Section 338(g) of the Code, or any similar provision of state, local or foreign Law, may be made with respect to the purchase of Shares or other transactions contemplated by this Agreement. Neither the Purchaser, the Company nor any of their Affiliates will elect to waive the carryback of any Tax attribute (including net operating and other losses) of the Company or any of its Subsidiaries.

Section 7.8 Directors and Officers; Indemnification and Insurance.

(a) Purchaser and the Company agree that, to the maximum extent permitted by the laws of the State of Delaware or any other applicable Laws, (i) all rights to indemnification, advancement of expenses and exculpation from liability for acts or omissions occurring prior to the Closing Date now existing in favor of the current or former directors, officers or employees of the Company or any of its Subsidiaries, including as provided in the Certificate of Incorporation and By-laws of the Company or in any agreements between the Company or any of its Subsidiaries and any current or former directors, officers or employees of the Company identified in Section 4.13 of the Company Disclosure Schedule, will survive the Closing and will continue in full force and effect in accordance with their respective terms for a period of not less than six years after the Closing Date (or, in the case of any agreement, in accordance with its terms), (ii) all rights to indemnification, advancement of expenses and exculpation from liability for acts or omissions occurring prior to the Closing Date now existing in favor of the current or former directors, officers or employees of the Company shall be presently vested contractual rights and shall not hereafter be eliminated or limited in any way whatsoever, and (iii) with respect to any right to indemnification or advancement of expenses for acts or omissions occurring prior to the Closing Date, the Company shall be the indemnitor of first resort, responsible for all such indemnification or advancement, without regard to any right to indemnification or advancement that any director, officer or employee of the Company may have from any direct or indirect shareholder of the Company (or any affiliate of such shareholder) and without right to seek subrogation, indemnity or contribution.

(b) As of or prior to the Closing, the Purchaser shall purchase, or cause the Surviving Corporation to purchase, “tail” coverage for a period of six (6) years following the Closing Date under the directors and officers liability insurance policy of the Company, as in effect on the date of this Agreement (the “Tail D&O Policy”), with coverage (including terms, conditions, retentions and limitations of liability) at least as favorable as the coverage under the existing Company policy. This Section 7.8 shall be for the benefit of, and shall be enforceable by, the current or former directors, officers and employees of the Company, and their respective heirs, executors, administrators and estates.

(c) Notwithstanding anything set forth herein to the contrary, in the event of any conflict or other inconsistency between any of the provisions set forth in this Section 7.8, on the one hand, and Section 7.11, on the other hand, the terms of this Section 7.8 shall control.

Section 7.9 Antitrust Approvals.

(a) As promptly as reasonably practicable following the execution of this Agreement, each of the Purchaser and the Company (so far as it is legally bound to do so) shall make, or shall cause its ultimate parent entity (as that term is defined in the HSR Act) to make, all pre-transaction notification filings required under the HSR Act, and required under any other applicable Antitrust Laws (which shall be made no later than ten (10) Business Days after the date hereof or on such other subsequent date as the Purchaser and the Company mutually agree or the earlier date required by the applicable

Law). Each of the Purchaser, on the one hand, and the Company, on the other hand, shall: (i) cooperate fully with each other and shall furnish to the other such necessary information and reasonable assistance as the other may reasonably request in connection with its preparation of any required filings under the HSR Act or any applicable Antitrust Laws; and (ii) keep the other party reasonably informed of any communication received by such party from, or given by such party to any Antitrust Authority and of any communication received or given in connection with any proceeding by a private party, in each case regarding the transactions contemplated hereby and in a manner that protects attorney-client or attorney work product privilege. Further, without limiting the obligations stated in this Section 7.9(a), the Purchaser and the Company shall each use its reasonable best efforts to respond to and comply with any request for information regarding the transactions contemplated hereby or filings under the HSR Act or any applicable Antitrust Laws from any Antitrust Authority. Neither the Purchaser, on the one hand, nor the Company, on the other hand, shall consent to any voluntary extension of any statutory deadline or waiting period or to any voluntary delay of the consummation of the transactions contemplated by this Agreement, at the behest of any Governmental Entity or otherwise, without the consent of the other party, which consent shall not be unreasonably withheld, conditioned or delayed.

(b) Without limiting the generality of the foregoing, each of the Purchaser and the Company shall provide to the other (or the other party’s outside counsel) upon request copies of all correspondence between such party and any Antitrust Authority relating to the transactions contemplated by this Agreement. The Purchaser and the Company may, as each reasonably deems advisable and necessary, designate any competitively sensitive materials provided to the other under this Section 7.9(b) as “clean room only,” “confidential material” or as “competitively sensitive information,” in accordance with the Confidentiality Agreements. Such materials and the information contained therein shall be given only to outside counsel or senior management of the recipient, subject to compliance with applicable Law, and will not be disclosed by such outside counsel or senior management to employees, officers, or directors of the recipient without the advance written consent of the party providing such materials. Subject to applicable Law, the Purchaser and the Company will consult and cooperate with each other in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, and proposals made or submitted to any Antitrust Authority regarding the transactions contemplated by this Agreement by or on behalf of any such party.

(c) The Purchaser and the Company will, with the exception of the payment of the filing fees pursuant to the HSR Act in accordance with Section 11.13, at their own expense, use their reasonable best efforts to obtain all required approvals from any Antitrust Authority, including approval under the HSR Act, and to avoid or eliminate each and every other impediment to Closing under the HSR Act as expeditiously as possible.

(d) Subject to the other obligations of the Parties as set forth in this Section 7.9, in no event shall the Company and the Signing Stockholders, without the prior written consent of the Purchaser (such consent not to be unreasonably withheld, conditioned or delayed), (i) agree to sell, divest, dispose of or hold separate any assets or

businesses of the Company or any of its Subsidiaries, or otherwise take or commit to take any action that could reasonably be anticipated to limit the Company or its Subsidiaries’ freedom of action with respect to, or their ability to retain, one or more Subsidiaries, businesses, product lines, assets or affiliations with any Special Affiliates, or (ii) agree or otherwise become subject to any restrictions, conditions, limitations, licensing requirements, or other understandings on or with respect to the assets or the operation of the business of the Company, any of its Subsidiaries or any Special Affiliate (other than, with respect to this clause (ii), as any of the foregoing may arise in the Ordinary Course of Business.

(e) If in connection with obtaining one (1) or more required approvals from any Antitrust Authority, the Purchaser is prohibited from acquiring any of the Dialysis Centers of the Company and its Subsidiaries, then the Company shall use its reasonable best efforts to assist the Purchaser in its efforts to, at its option, either (i) market and sell any such Dialysis Centers (the “Divested Dialysis Centers”) to a third party (the “Dialysis Centers Divestiture”), or (ii) sell such Dialysis Centers (the “Retained Dialysis Centers”) to a newly formed entity (“Retained Dialysis Centers Co.”) owned directly by one (1) or more of the Stockholders or their Affiliates (the “Retained Dialysis Centers Distribution”) in exchange for the Retained Dialysis Centers Amount, or any combination thereof. In connection with the Dialysis Centers Divestiture (but subject to Section 10.2(d)), the Parties agree that (i) the Purchaser and the Company and their respective counsel shall have primary responsibility for the preparation and negotiation of the transaction terms (including price), conditions, agreements and documentation (the “Divestiture Agreements”), subject to compliance with applicable Law, and (ii) at the Purchaser’s reasonable request, the Company shall cause the Company and the Company’s management to take all actions reasonably required at the direction of the Purchaser to (A) participate in the marketing and sale process for the Dialysis Centers Divestiture, including the preparation of due diligence information, the answering of questions from potential purchasers, the preparation of marketing materials and participation in management presentations, and (B) execute the Divestiture Agreements on the terms and conditions (including price) negotiated and documented in the Divestiture Agreements by the Purchaser, the Company and their respective counsel, it being acknowledged and agreed by the Purchaser that none of the Stockholders shall have any liability or obligation to the buyer(s) thereunder pursuant to such divestiture agreements other than with respect to any post-closing restrictive covenants entered into in connection therewith so long as they are no more restrictive than the restrictive covenants set forth herein. In connection with the Retained Dialysis Centers Distribution, the Company shall prepare all required documentation to implement the Retained Dialysis Centers Distribution (including with respect to employment matters involving employees of the Company and its Subsidiaries, as to which the Purchaser and the Company shall reasonably cooperate), which documentation shall not contain any restrictive covenants against Retained Dialysis Centers Co. in respect of non-competition or non-solicitation purporting to restrict the activity of any Retained Dialysis Center (it being acknowledged that this sentence shall not limit the restrictions contained in Section 7.12), but which shall otherwise be subject to the Purchaser’s prior written approval (such approval not to be unreasonably withheld, delayed or otherwise conditioned), and execute all such documentation to effect the Retained Dialysis Centers Distribution. If a Retained

Dialysis Centers Distribution is to take place, such transaction shall be consummated immediately prior to the Closing of the transactions contemplated hereby. If a Dialysis Centers Divestiture is to take place, and is required by applicable Law to take place prior to the Closing, such transaction shall be consummated immediately prior to the Closing of the transactions contemplated hereby.

Section 7.12 Non-Competition; Non-Solicitation. As a condition precedent to the Purchaser’s obligations to enter into and perform its obligations under this Agreement:

(a) Each Management Stockholder, on his or its own behalf and on behalf of his or its Affiliates, agrees that for a period equal to [*] after the Closing Date (the “Non-Competition Period”), he/it, and his/its Affiliates, shall not, directly or indirectly, either for himself/itself or for any other Person, participate in an enterprise that is located anywhere within [*] of any Transferred Center in the business of selling or providing dialysis and/or nephrology services. For purposes of this Agreement, the term “participate” includes any direct or indirect interest in any enterprise, whether as an officer, director, manager, employee, partner, sole proprietor, agent, representative, independent contractor, consultant, franchisor, franchisee, creditor, shareholder, owner or otherwise; provided, however, that (i) the term “participate” shall not include either ownership of [*] or less of the stock of a publicly held corporation whose stock is traded on a nationally or internationally recognized securities exchange, automated dealer quotation system or in a United States or foreign over-the-counter-market, and (ii) the restrictions set forth in this Section 7.12 shall not apply to any Management Stockholder’s participation (A) [*] or (B) [*].

(b) Each Management Stockholder, on his own behalf or on behalf of his Affiliates, agrees that for a period equal to [*] after the Closing Date (the “Non-Solicitation Period”), he shall not, directly or indirectly, either for himself or for any other Person:

(c) Each Non-Solicitation Stockholder, on his own behalf or on behalf of his Controlled Affiliates, agrees that for a period equal to the Non-Solicitation Period, he shall not, directly or indirectly, either for himself or for any other Person solicit for employment or hire any member of the Non-Solicitation Group; [*].

(d) The Parties hereby acknowledge and agree that the term “current”, as used in this Section 7.12 in reference to any Person means that such Person is or was, [*], employed by, a Special Affiliate of, or an independent contractor of, any of the Purchaser, the Company or any of the Company’s Subsidiaries, Dialysis Centers or joint ventures.

(e) Each Management Stockholder and Non-Solicitation Stockholder agrees on his/its own behalf and on behalf of his/its Affiliates, that the covenants set forth in this Section 7.12 impose a reasonable restraint on him or it in light of the activities and business of the Company and its current plans.

(f) Each Management Stockholder and Non-Solicitation Stockholder, severally and not jointly with any other Person, recognizes and affirms that in the event of breach of any of the provisions of this Section 7.12, money damages would be inadequate and that the Purchaser would have no adequate remedy at law. Accordingly, each Management Stockholder and Non-Solicitation Stockholder, severally and not jointly with any other Person, agrees that the Purchaser shall have the right, in addition to any other rights and remedies existing in their favor, to enforce its rights and the Management Stockholder’s and Non-Solicitation Stockholder’s obligations under Section 7.12 not only by an action or actions for damages, but also by an action or actions for specific performance, injunctive and/or other equitable relief, without any requirement or obligation to post a bond or to prove damages, in order to enforce or prevent any violations (whether anticipatory, continuing or future) of the provisions of this Section 7.12 (including, without limitation, the extension of the Non-Competition Period and/or Non-Solicitation Period by a period equal to (i) the length of any violation of Section 7.12(a), Section 7.12(b) or Section 7.12(c), as applicable, plus (ii) the length of any Litigation necessary to stop such violation). In the event of a breach or violation by a Management Stockholder or Non-Solicitation Stockholder of any of the provisions of

Section 7.12(a), Section 7.12(b) or Section 7.12(c), as applicable, the running of the Non-Competition Period and Non-Solicitation Period, as applicable, shall be tolled with respect to such breaching Management Stockholder or Non-Solicitation Stockholder during the continuance of any actual breach or violation.

(g) Notwithstanding anything set forth herein to the contrary, the Parties acknowledge and agree that, (i) effective as of the Closing, the restrictions set forth in this Section 7.12 supersede and replace in their entirety any other restrictive covenants in respect of or otherwise relating to non-competition or non-solicitation between the Management Stockholders, on the one hand, and the Purchaser, the Company and/or any of their respective Affiliates, on the other and (ii) none of the restrictions set forth in this Section 7.12 shall in any way restrict any of the activities of any dialysis centers identified in Section 7.12 of the Company Disclosure Schedule as to which [*], provided that (A) [*] and (B) [*].

“Controlled Affiliates” means, for the purposes of this Section 7.12, Affiliates of which the applicable Stockholder possesses the power to direct or cause the direction of the management and policies of such Affiliate, which in the case of an entity, shall mean the power to vote fifty percent (50%) or more of the securities (on a fully diluted basis) having ordinary voting power for the election of directors or managers of such Affiliate; [*].

Section 7.13 Regulatory Spinoff. If the conditions to Closing set forth in ARTICLE VIII of this Agreement have not been satisfied or waived (other than with respect to actions the respective Parties will take at the Closing itself) solely due to the failure of the Parties to obtain the consent of Governmental Entities of one or more U.S. States to the transactions contemplated hereby (the “Consent States”), then the Parties shall spinoff the Subsidiaries of the Company operating in such Consent States (the “Spinoff Subsidiaries”) in order to permit the satisfaction of such Closing conditions (the “Spinoff”); provided, however, the Purchaser may elect to delay the Spinoff (and the Closing) until February 28, 2012 if it reasonably believes such outstanding consents will be obtained on or prior to such date. In the event of the Spinoff, then the Stockholders and the Company shall form a new entity (“Spinco”) to be owned directly by the Stockholders on a pro rata basis consistent with their ownership interest in the Company (on a fully diluted basis) to acquire and hold the Spinoff Subsidiaries and [*].

Except as permitted by the terms of such Confidentiality Agreements (as if the Stockholders were a party thereto), the Stockholders will not, and will cause their Affiliates and representatives not to, directly or indirectly, disclose to any third party any confidential or proprietary information of the Company and its Subsidiaries, provided, however, that the foregoing restriction shall not prohibit any disclosure required by any applicable legal requirement, so long as, to the extent legally permissible, such Stockholder provides Purchaser with reasonable prior notice of such disclosure and a reasonable opportunity to seek an appropriate protective order.

The Losses of the Purchaser Indemnified Parties described in this Section 10.1 as to which the Purchaser Indemnified Parties are entitled to indemnification are collectively referred to as “Purchaser Losses”.

Section 10.2 Indemnification of the Stockholder Indemnified Parties. Subject to the other provisions of this ARTICLE X other than Section 10.1(f), the Purchaser shall indemnify, defend and hold harmless the Stockholder Indemnified Parties from and against any and all direct or indirect Losses incurred, resulting or arising from:

(a) any breach of any Fundamental Representations and Warranties made by the Purchaser in this Agreement;

(b) any willful breach (i.e., an act taken with the actual knowledge that such act would cause a breach) by the Purchaser or its Affiliates of any of the agreements set forth on Exhibit 10.1(c)(i) hereof, subject in each case to any applicable monetary or other limitations on remedies provided therein;

For the avoidance of doubt, Purchaser shall have no obligation to indemnify Stockholder Indemnified Parties (or their direct or indirect owners) for any Liabilities, including Taxes, associated with unrelated business taxable income, U.S. effectively connected income or fixed or determinable annual or periodic income or any breaches by the Stockholders of their covenants, agreements or undertakings with their Affiliates or direct or indirect owners.

The Losses of the Stockholder Indemnified Parties described in this Section 10.2 as to which the Stockholder Indemnified Parties are entitled to indemnification are collectively referred to as “Stockholder Losses.”

Section 10.3 Indemnification Procedure. A party making a claim for indemnification under Section 10.1 or Section 10.2 shall be, for the purposes of this Agreement referred to as an “Indemnified Party” and a party against whom such claims are asserted under Section 10.1 or Section 10.2 shall be, for the purposes of this Agreement, referred to as an “Indemnifying Party.” All claims by any Indemnified Party under Section 10.1 or Section 10.2 shall be asserted and resolved as follows:

(a) In the event that (i) any action, application, suit, demand, claim or legal, administrative, arbitration or other alternative dispute resolution proceeding, hearing or investigation (each, a “Proceeding”) is asserted or instituted by any Person other than the Parties or their Affiliates which could give rise to damages for which an Indemnifying Party could be liable to an Indemnified Party under this Agreement (such Proceeding, a “Third Party Claim”) or (ii) any Indemnified Party under this Agreement shall have a claim to be indemnified by any Indemnifying Party under this Agreement which does not involve a Third Party Claim (such claim, a “Direct Claim” and, together with Third Party Claims, “Indemnification Claims”), the Indemnified Party shall, promptly after it becomes aware of a Third Party Claim (and in any event, within thirty (30) days), or facts supporting a Direct Claim, send to the Indemnifying Party a written notice specifying the nature of such Proceeding giving rise to any such Third Party Claim or Direct Claim in reasonable detail in light of the facts then known to the Indemnified Party, and, if practicable in the Indemnified Party’s reasonable judgment, the amount or estimated amount thereof (which amount or estimated amount shall not be conclusive of the final amount, if any, of such Proceeding) (a “Claim Notice”), together with copies of all notices and documents (including court papers) served on or received by the Indemnified Party in the case of a Third Party Claim, provided, however, that a delay (including a delay beyond the aforementioned thirty (30) day period) in notifying the Indemnifying Party (or delivering copies of the aforementioned notices and documents) shall not relieve the Indemnifying Party of its obligations under Section 10.1 or Section 10.2 except to the extent that (and only to the extent that) (x) the applicable Claims Period has expired prior to such notice or (y) the Indemnifying Party shall have been materially prejudiced by the failure of the Indemnified Party to give such notice or deliver such documents or notices, in which case the Indemnifying Party shall be relieved of its obligations under Section 10.1 or Section 10.2 only to the extent of such material prejudice.

(b) In the event of a Third Party Claim, the Indemnifying Party shall have the right to defend against and direct the defense of such Third Party Claim, provided, however, that the Indemnifying Party shall have acknowledged in writing to the Indemnified Party its obligation to indemnify the Indemnified Party as provided hereunder (subject to the limitations set forth herein). If the Indemnifying Party elects to defend against and direct the defense of any Third Party Claim, it shall within thirty (30) days (or sooner, if the nature of the Third Party Claim so requires) (the “Dispute Period”) notify the Indemnified Party of its intent to do so; provided, however,

that the Indemnifying Party must conduct its defense of the Third Party Claim actively and diligently thereafter in order to preserve its rights in this regard. If the Indemnifying Party does not elect within the Dispute Period to defend against and direct the defense of any Third Party Claim, fails to notify the Indemnified Party of its election during the Dispute Period, contests its obligation to indemnify the Indemnified Party for such damages under this Agreement or fails to actively and diligently conduct its defense of the Third Party Claim, the Indemnified Party may defend against and direct the defense of such Third Party Claim. If the Indemnifying Party elects to defend against and direct the defense of such Third Party Claim and appoint counsel in connection therewith, (i) the Indemnifying Party shall use its commercially reasonable efforts to defend and protect the interests of the Indemnified Party with respect to such Third Party Claim, (ii) the Indemnified Party may participate, at its own expense, in the defense of such Third Party Claim (though not as counsel of record) and (iii) the Indemnified Party shall have the right to engage separate counsel in connection therewith, but such counsel shall appear as counsel of record for the Indemnified Party and the Indemnifying Party shall bear the reasonable fees, costs and expenses of such separate counsel if, and only if, (x) in the reasonable opinion of counsel to the Indemnified Party, a conflict or potential conflict exists between the Indemnified Party and the Indemnifying Party that would make such separate representation advisable, (y) the Indemnifying Party requests that the Indemnified Party participate in such defense or (z) the Indemnifying Party shall not have engaged counsel within a reasonable time (but not more than thirty (30) days) after notice of the institution of such Third Party Claim. Except as provided in the preceding sentence, nothing in this Section 10.3 shall require the Indemnifying Party to be responsible for the fees and expenses of more than one law firm for one or more Indemnified Parties at any time in connection with the defense against a Third Party Claim. If reasonably requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in defending and contesting any Proceeding giving rise to the Third Party Claim which the Indemnifying Party defends. No Third Party Claim may be settled or compromised, or offered to be settled or compromised, or a default permitted or an entry of any judgment consented to (each, a “Settlement”) (A) by the Indemnified Party without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed), or (B) by the Indemnifying Party without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed); provided that, in the case of a consent from an Indemnified Party, such consent shall not be required in the event such Settlement (1) includes a full release of the Indemnified Party and (2) involves only monetary damages that will be paid in full by the Indemnifying Party. Notwithstanding the foregoing, if a Third Party Claim seeks relief other than the payment of monetary damages or if any relief sought would result in the imposition of an Order that would materially restrict the future activity or conduct of the Indemnified Party or any of its Affiliates, then the Indemnified Party alone shall be entitled to contest, defend and resolve (subject, with respect to any Settlement, to obtaining the consent of the Indemnifying Party, such consent not to be unreasonably withheld or delayed) such Third Party Claim in the first instance and, if the Indemnified Party does not contest, defend and resolve such Third Party Claim, the Indemnifying Party shall then have the right to contest and defend (but not enter into a Settlement without the consent of the

Indemnified Party, which consent may be withheld in the Indemnified Party’s sole discretion) such Third Party Claim. In the event any Indemnified Party enters into a Settlement with respect to any Third Party Claim in violation of either of the two immediately preceding sentences, such Indemnified Party shall be deemed to have waived all rights against the Indemnifying Party for indemnification under this Section 10.3 with respect to such Third Party Claim.

(c) After any final decision, judgment or award shall have been rendered by a Governmental Entity or arbitrator of competent jurisdiction and the expiration of the time in which to appeal therefrom, or a Settlement or arbitration shall have been consummated, or the Indemnified Party and the Indemnifying Party shall have arrived at a mutually binding agreement with respect to an Indemnification Claim hereunder, the Indemnified Party shall forward to the Indemnifying Party notice of any sums due and owing by the Indemnifying Party pursuant to this Agreement with respect to such matter and the Indemnifying Party shall make prompt payment thereof by wire transfer in immediately available funds within five (5) Business Days after the date of such notice or, if required earlier, pursuant to the terms of the agreement reached with respect to the Indemnification Claim.

(d) In the event of a Direct Claim, the Indemnifying Party shall notify the Indemnified Party within thirty (30) days of receipt of a Claim Notice whether the Indemnifying Party disputes such Indemnification Claim. From and after the delivery of a Claim Notice under this Agreement, at the reasonable request of either Party, each Party shall grant the other and its Agents reasonable access to the books, records, Agents and properties of such Party to the extent reasonably related to the matters to which the Claim Notice relates. All such access shall be granted during normal business hours and shall be granted under conditions which will not unreasonably interfere with the business and operations of such Party. The Party requesting access will not, and shall use its reasonable best efforts to cause its Agents not to, use (except in connection with such Claim Notice) or disclose to any third person other than the Party’s Agents (except as may be required by applicable Law) any information obtained pursuant to this Section 10.3(d) which is designated as confidential by the other Party. Notwithstanding the foregoing, neither Party shall have access to (i) any medical or other employee information that is contained in the personnel records of the other Party or its Affiliates and the disclosure of which would subject that Party or such Affiliate to risk of liability, (ii) any information which is subject of any attorney-client or other privilege or immunity from disclosure in favor of the other Party or its Affiliates or (iii) any information the disclosure of which would cause the other Party or any of its Affiliates to violate applicable Law.

(e) Notwithstanding the foregoing, any Tax Proceeding shall be governed by Section 7.7(f) and not by the provisions of this Section 10.3.

Section 10.4 Investigation; Survival; Claims Period.

(a) The rights of an Indemnified Party to indemnification or to assert or recover on any claim shall not be affected by any investigation conducted with respect to,

or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy of or compliance with, any of the representations, warranties, covenants or agreements set forth in this Agreement. The waiver of any condition based on the accuracy of any representation or warranty, or the performance or compliance with any covenant or agreement, shall not affect the right to indemnification pursuant to this ARTICLE X based on such representations, warranties, covenants or agreements.

(b) Except as expressly set forth in this Section 10.4, all representations and warranties set forth in ARTICLE IV, ARTICLE V and ARTICLE VI of this Agreement and all covenants and agreements required to be performed or complied with at or prior to the Closing shall expire as of the Closing Date (and no indemnification claims may be brought under such representations and warranties or covenants and agreements at any time).

(d) The Claims Period for indemnification under Section 10.1(a) shall expire on the third (3rd) anniversary of the Closing Date.

(e) The Claims Period for indemnification under Section 10.1(d) shall expire (i) with respect to the covenants set forth in Section 7.1(a)(ii), Section 7.1(a)(iii), Section 7.1(a)(v), Section 7.1(a)(vii), Section 7.1(a)(ix), Section 7.1(a)(x), Section 7.1(a)(xiii), Section 7.1(a)(xx) (or under Section 4.10(b) solely with respect to any of the foregoing enumerated provisions of Section 7.1(a)), Section 7.3(a), Section 7.3(d) and Section 7.17, on the Escrow Release Date and (ii) with respect to each covenant to be performed after the Closing (“Post-Closing Covenants”), on the date that is six (6) months following the date upon which such covenant was to be fully performed in accordance with its terms.

(f) The Claims Period for a claim for indemnification under Section 10.1(f) with respect to federal income Taxes shall expire on July 1, 2015, and the Claims Period for a claim for indemnification under Section 10.1(f) other than with respect to federal income Taxes shall expire on the earlier of March 31, 2017 or ninety (90) days following the expiration of the longest applicable statute of limitations. The covenants under Section 7.7 shall survive coterminous with the Tax indemnity obligation with respect to which such covenants relate.

(g) The Claims Period for a claim for indemnification under Section 10.1(c), Section 10.1(e) and Section 10.1(g) shall expire on the Escrow Release Date.

(h) No claim or cause of action for indemnification under ARTICLE X may be made or brought (i) prior to Closing; or (ii) following the expiration of the applicable Claims Period; provided that, in the event a notice of any claim for indemnification under ARTICLE X shall have been made post-Closing, but prior to the expiration of the applicable Claims Period, then such claim for indemnification (and only such claim for indemnification), if not resolved prior to the expiration of the Claims Period, shall survive until such time as that claim for indemnification is fully and finally resolved.

Section 10.5 Liability Limits.

(a) The Purchaser Indemnified Parties may not make a claim for indemnification under (i) Section 10.1(d) (solely to the extent such claim relates to a breach of Section 7.1(a)(ii), Section 7.1(a)(iii), Section 7.1(a)(v), Section 7.1(a)(vii), Section 7.1(a)(ix), Section 7.1(a)(x), Section 7.1(a)(xiii), Section 7.1(a)(xx) (or pursuant to a claim for breach or inaccuracy of the representations and warranties of Section 4.10(b) solely with respect to any of the foregoing enumerated provisions of Section 7.1(a)), Section 7.3(a), Section 7.3(d), or Section 7.7 (solely to the extent that such claim is not in respect of federal income Taxes)) or (ii) Section 10.1(f) (solely to the extent such claim is not in respect of federal income Taxes) unless and until, for each such clause (as applicable), the aggregate amount of Purchaser Losses for which the Purchaser Indemnified Parties are entitled to seek indemnification exceeds One Million Dollars ($1,000,000), in which event the Purchaser Indemnified Parties may claim indemnification for all such Purchaser Losses (including, for the avoidance of doubt, amounts up to and including such initial $1,000,000) up to the limits provided herein.

Subject to the limitations set forth in this ARTICLE X, Purchaser Losses for which the Purchaser Indemnified Parties may make a claim for indemnification shall be: first satisfied from the Escrow Fund, and only after the Escrow Fund has been exhausted or otherwise released, satisfied by each Stockholder, on a several and not joint basis, each in accordance with and limited to such Stockholder’s respective Pro Rata Percentage. In the case of Purchaser Losses (i) pursuant to a claim for a breach of Section 7.1(a)(ii), Section 7.1(a)(iii), Section 7.1(a)(v), Section 7.1(a)(vii), Section 7.1(a)(ix), Section 7.1(a)(x), Section 7.1(a)(xiii), Section 7.1(a)(xx) (or pursuant to a claim for breach or inaccuracy of the representations and warranties of Section 4.10(b) solely with respect to any of the foregoing enumerated provisions of Section 7.1(a)), Section 7.3(a), and Section 7.3(d), any and all recoveries in respect of Purchaser Losses shall be limited in the aggregate by an indemnification cap equal to One Hundred Million Dollars ($100,000,000) and (ii) pursuant to any other claim that may be made under this ARTICLE X, any and all recoveries in respect of Purchaser Losses shall be limited to, in the case of each Stockholder, such Stockholder’s Proceeds Cap (except with respect to claims under Section 7.12 or Section 7.14, as described in the following paragraph).

Notwithstanding anything to the contrary herein and in addition to any other limitations on indemnification in this Agreement, with respect to claims for Purchaser Losses related to Renal Advantage Partners, LLC and its Subsidiaries (excluding any claims made pursuant to Sections 10.1(c), (d) (other than claims for breaches of Section 7.7), (e) and (g)), the Stockholders shall only be liable for fifty-one percent (51%) of any such Purchaser Losses that would otherwise be indemnifiable hereunder provided, however, that with respect to claims made (i) [*], and (ii) for Taxes pursuant to Section 10.1(f), 7.7(j), or 7.7(g) such 51% limitation shall only apply to Taxes of Renal Advantage

Partners, LLC and its Subsidiaries (i.e., not any Taxes due and payable by the Company or any other Subsidiary, even if it relates to Renal Advantage Partners, LLC and its Subsidiaries (other than in the case of Taxes due with respect to consolidated or other group Tax Returns that include Renal Advantage Partners, LLC and its Subsidiaries, solely to the extent such Taxes are attributable to their operations or activities)). Notwithstanding anything to the contrary herein regarding the allocation of Purchaser Losses in accordance with each Stockholder’s Pro Rata Percentage, any claims for indemnification for Purchaser Losses as a result of: (A) a breach by a particular Stockholder of a Post-Closing Covenant applicable to such Stockholder (other than Section 7.12 and Section 7.14) or by a Stockholder of any of its Fundamental Representations and Warranties set forth in ARTICLE V hereof shall be satisfied in accordance with the terms hereof exclusively by such particular Stockholder (and not any other Stockholder), including by the release to the applicable Purchaser Indemnified Party of the balance of such Stockholder’s Pro Rata Percentage of the Escrow Fund, but limited in amount to such Stockholder’s Proceeds Cap, or (B) a breach by a particular Stockholder of Section 7.12 or Section 7.14 shall in the first instance be satisfied in accordance with the terms hereof exclusively by such particular Stockholder (and not any other Stockholder), including by the release to the applicable Purchaser Indemnified Party of the balance of such Stockholder’s Pro Rata Percentage of the Escrow Fund, but limited in amount to fifty percent (50%) of such Stockholder’s Proceeds Cap; provided, that, if the amount of a Purchaser Loss referenced in this clause (B) exceeds fifty percent (50%) of such Stockholder’s Proceeds Cap, then any such excess Purchaser Loss shall be satisfied by the other Stockholders, on a several and not joint basis in accordance with and limited to each such other Stockholder’s respective Pro Rata Percentage, and further limited to fifty percent (50%) of each such other Stockholder’s Proceeds Cap.

(b) Notwithstanding anything to the contrary contained in this Agreement, the amount of indemnity otherwise payable pursuant to Section 10.1 with respect to any Purchaser Losses shall be reduced to the extent that the facts or circumstances giving rise to any such Purchaser Losses have (or any related liability has) previously been taken into account in determining any post-Closing adjustment contemplated by Section 3.9 or any previous indemnification payment made pursuant to this ARTICLE X.

(c) In calculating the amount of Losses relating to Taxes otherwise indemnifiable under Section 10.1, the Indemnifying Party and Indemnified Party shall agree as to the Pre-Closing Benefits that are available (based either on (i) the past practices of the Company and its Subsidiaries in filing their Tax Returns or (ii) standards then applicable for filing Tax Returns (clauses (i) and (ii), the “Availability Principles”)) and if the Indemnifying Party and the Indemnified Party are unable to agree, then the parties shall engage PricewaterhouseCoopers LLP to calculate the amount of Pre-Closing Benefits that are available for such purpose (based on the Availability Principles). The Parties shall share the cost of PricewaterhouseCoopers LLP’s services on a 50-50 basis.

(d) Notwithstanding anything to the contrary contained in this Agreement, solely for purposes of determining whether any breach of any Fundamental Representations and Warranties has occurred or any inaccuracy in any such representation or warranty exists and for calculating Purchaser Losses in respect thereof,

all qualifications, provisions or exceptions for “material,” “materiality,” “in all material respects” (or correlative meanings) and “Company Material Adverse Effect” and “Purchaser Material Adverse Effect” set forth in such representation or warranty shall be deemed to have been made or given for the purposes of this Agreement as though there were no such qualification, provision or exception.

(e) The calculation of any Purchaser Loss will reflect the amount of any insurance proceeds received in cash by the Purchaser Indemnified Parties in respect of such Purchaser Loss in such year, net of the present value of any reasonably probable increase in insurance premiums or other charges paid or to be paid by the Purchaser Indemnified Parties resulting from such Purchaser Loss and all costs and expenses incurred by any Purchaser Indemnified Party in recovering such proceeds from its insurers. The calculation of any Stockholder Loss will reflect the amount of any insurance proceeds received in cash by the Stockholder Indemnified Parties in respect of such Stockholder Loss in such year, net of the present value of any reasonably probable increase in insurance premiums or other charges paid or to be paid by the Stockholder Indemnified Parties resulting from such Stockholder Loss and all reasonable costs and expenses directly incurred by any Stockholder Indemnified Party in recovering such proceeds from its insurers. The amount of any Loss subject to indemnification under this ARTICLE X (whether a Purchaser Loss or a Stockholder Loss) shall be net of any Tax benefit actually realized by the Indemnified Party and/or its Affiliates arising from the incurrence or payment of such Loss and any correlative adjustments resulting from such Loss.

(f) Without affecting the Purchaser’s right to submit indemnification claims hereunder, but before the Purchaser shall be entitled to obtain recovery in respect of any such claims, the Purchaser agrees to cause the Company to use commercially reasonable efforts to pursue any indemnification claims it may have under the Renal Advantage SPA in accordance with the terms and conditions thereof. If the Purchaser Indemnified Party receives an indemnification payment hereunder in respect of an indemnifiable loss (an “Indemnity Payment”) and shall subsequently receive payment in respect of such indemnifiable loss pursuant to the indemnification provisions of the Renal Advantage SPA, then the Purchaser Indemnified Parties shall pay to the Indemnifying Parties the amount so received up to an amount equal to the Indemnity Payment. Indemnification payments received by the Company or any of its Affiliates under the Renal Advantage SPA shall not reduce or be applied towards the indemnity limits under Section 10.5.

Section 10.6 Limitation of Remedy. Other than with respect to Fraud Based Purchaser Claims and Fraud Based Stockholder Claims, the Purchaser, the Surviving Corporation and the Stockholders acknowledge and agree that, following the Closing, the sole and exclusive remedy of the Parties with respect to any breach or inaccuracy of any of the representations, warranties, covenants or agreements of the Parties set forth herein shall be indemnification in accordance with this ARTICLE X or specific performance or injunctive or similar relief as specifically provided for in this Agreement.

100

Section 10.7 Treatment of Indemnity Payments. To the extent permitted by applicable Tax Law, all payments made pursuant to Section 10.1 and Section 10.2 shall be deemed adjustments to the Merger Consideration for Tax purposes.

Section 10.8 Specific Performance. Each Party hereby acknowledges that the rights of each other Party to consummate the transactions contemplated hereby are special, unique and of extraordinary character and that, in the event that any Party violates or fails or refuses to perform any covenant or agreement made by it herein, the other Party or Parties may be without an adequate remedy at law. In the event that any Party violates or fails or refuses to perform any covenant or agreement made by such Party herein, the other Party or Parties may, subject to the terms hereof and in addition to any remedy at law for damages or other relief contemplated by this Agreement, institute and prosecute an action in a court as specified in Section 11.6 to enforce specific performance of such covenant or agreement or seek any other equitable relief. Unless this Agreement is terminated in accordance with its terms, the Company and the Stockholders shall be entitled to seek specific performance against the Purchaser to consummate the Merger in accordance with the terms of this Agreement and the Purchaser shall be entitled to seek specific performance against the Company and the Stockholders to consummate the Merger in accordance with the terms of this Agreement.

(a) Each Party agrees that any legal action or other legal proceeding relating to this Agreement or the enforcement of any provision of this Agreement shall be brought or otherwise commenced exclusively in any state or federal court located in the Borough of Manhattan, City of New York, State of New York. Each Party:

(i) expressly and irrevocably consents and submits to the jurisdiction of each state and federal court located in the Borough of Manhattan, City of New York, State of New York (and each appellate court located in the State of New York) in connection with any such legal action or proceeding, including to enforce any Order or award;

(ii) consents to service of process in any such action or proceeding in any manner permitted by the Laws of the State of New York, and agrees that service of process by registered or certified mail, return receipt requested, at its address specified pursuant to Section 11.1 (and in the case of the Stockholders, the address of the Stockholder Representative specified pursuant to such Section 11.1) is reasonably calculated to give actual notice;

103

(iii) agrees that each state and federal court located in the Borough of Manhattan, City of New York, State of New York shall be deemed to be a convenient forum for such action or proceeding;

(iv) waives and agrees not to assert (by way of motion, as a defense or otherwise), in any such action or proceeding commenced in any state or federal court located in the State of New York any claim that such Party is not subject personally to the jurisdiction of such court, that such legal proceeding has been brought in an inconvenient forum, that the venue of such proceeding is improper or that this Agreement or the subject matter hereof or thereof may not be enforced in or by such court; and

(v) agrees to the entry of an Order to enforce any Order or award made pursuant to this Section by the state and federal courts located in the Borough of Manhattan, City of New York, State of New York and in connection therewith hereby waives, and agrees not to assert by way of motion, as a defense, or otherwise, any claim that such resolution, settlement, Order or award is inconsistent with or violative of the Laws or public policy of the Laws of the State of New York or any other jurisdiction.

(b) In the event of any legal action or other legal proceeding relating to this Agreement or the enforcement of any provision of this Agreement, the prevailing party shall be entitled to payment by the non-prevailing party of all costs and expenses (including reasonable attorneys’ fees) incurred by the prevailing party, including any costs and expenses incurred in connection with any challenge to the jurisdiction or the convenience or propriety of venue of proceedings before any state or federal court located in the Borough of Manhattan, City of New York, State of New York.

Section 11.7 Waiver of Jury Trial. EACH PARTY TO THIS AGREEMENT ACKNOWLEDGES AND AGREES THAT ANY ACTION OR PROCEEDING WHICH MAY ARISE RELATING TO THIS AGREEMENT, ANY ANCILLARY DOCUMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, AND WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE, IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE, IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUCH ACTION OR PROCEEDING (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE). EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY SUCH ACTION OR PROCEEDING, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 11.7. THE PARTIES AGREE THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT

104

AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE THEIR RESPECTIVE RIGHTS TO TRIAL BY JURY.

Section 11.8 Severability. Any provision hereof that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by Law, each Party hereby waives any provision of Law that renders any provision hereof prohibited or unenforceable in any respect. If any provisions herein shall be adjudged to be void or invalid as going beyond what is reasonable in all the circumstances or for any other reason but would be valid if part of the wording thereof were deleted or the periods thereof reduced or the range of activities or area dealt with thereby reduced in scope, it is the Parties’ intention that such restrictions shall apply with such modifications as may be necessary to make them valid and effective, to the maximum extent permitted by applicable Law.

Section 11.9 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together will constitute but one and the same instrument. Signatures delivered by facsimile or as email attachments shall be as effective as originals.

Section 11.10 Parties in Interest; Representation of Seller Group. Certain provisions of this Agreement are intended for the benefit of, and shall be enforceable by, each of the Holders. Subject to the preceding sentence, nothing expressed or implied herein is intended, or shall be construed, to confer upon or give any Person other than the Parties and the Parent Guarantor, and their successors or permitted assigns, any right, remedy, claim, obligation or liability under or by reason of this Agreement, or result in such Person being deemed a third-party beneficiary hereof; provided, that any Person referenced in Section 7.8, Section 7.11 or Section 9.2 is intended to be, and shall be, an express intended third-party beneficiary thereof, and may enforce that provision directly. Each of the Parties hereby agrees, on its own behalf and on behalf of its directors, members, partners, officers, employees and Affiliates, that Ropes & Gray LLP (“R&G”) may serve as counsel to each and any of the Stockholder Representative, the Stockholders and their respective Affiliates other than the Company and its Subsidiaries (individually and collectively, the “Seller Group”), 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, R&G may serve as counsel to the Seller Group or any director, member, partner, officer, employee or Affiliate of the Seller Group, 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 prior representation or any continued representation of the Company and/or any of its Subsidiaries, and each of the Parties hereby consents thereto and waives any conflict of interest arising therefrom, and each of such Parties shall cause any Affiliate thereof to consent to waive any conflict of interest arising from such representation. The Purchaser further agrees that, as to all communications among R&G, the Company and the Stockholders or any of their respective Affiliates prior to the Closing Date that are related to the negotiation, preparation, execution and

105

delivery of this Agreement and the consummation of the transactions contemplated hereby, the attorney-client privilege and the expectation of client confidence belongs to the Stockholders and may be controlled by the Stockholder Representative and shall not pass to or be claimed by the Purchaser or the Company. Notwithstanding the foregoing, (a) in the event that a dispute arises between the Purchaser, the Company and a third party other than a party to this Agreement after the Closing, the Company may assert the attorney-client privilege to prevent disclosure of confidential communications by R&G to such third party; provided, however, that the Company may not waive such privilege without the prior written consent of the Stockholder Representative and (b) the foregoing waiver and agreement by the Purchaser shall not extend to any communication not involving the negotiation, preparation, execution and delivery of this Agreement and the consummation of the transactions contemplated hereby, or to communications other than those between R&G on the one hand, and the Company, the Stockholder Representative and the Stockholders or any of their respective Affiliates on the other hand.

Section 11.11 Waiver. Any agreement on the part of a Party to any extension or waiver of any provision hereof shall be valid only if set forth in an instrument in writing signed on behalf of such Party. A waiver by a Party of the performance of any covenant, agreement, obligation, condition, representation or warranty shall not be construed as a waiver of any other covenant, agreement, obligation, condition, representation or warranty. A waiver by any Party of the performance of any act shall not constitute a waiver of the performance of any other act or an identical act required to be performed at a later time.

Section 11.12 Integration. The Confidentiality Agreements, this Agreement, and the documents executed pursuant hereto or in connection herewith supersede all negotiations, agreements and understandings among the Parties with respect to the subject matter hereof and constitute the entire agreement among the Parties with respect thereto.

Section 11.13 Fees and Expenses. Unless otherwise specifically provided pursuant to this Agreement, all fees and expenses incurred in connection with this Agreement, and the transactions contemplated hereby shall be paid by the Party incurring such fees and expenses; provided, however, that the Stockholders shall bear all expenses incurred by the Stockholder Representative and the Stockholders. Notwithstanding any statement or provision herein to the contrary and with the exception of the filing fee under the HSR Act which shall be borne fifty percent (50%) by the Purchaser and fifty percent (50%) by the Company, the fees and expenses related to filings, permits, authorizations, consents and approvals as may be required under, and other applicable requirements of, the HSR Act and other similar Antitrust Laws, shall be borne by the Party incurring such expenses.

Section 11.14 Stockholder Representative.

(a) By the execution and delivery of this Agreement, including counterparts thereof, each Stockholder hereby irrevocably constitutes and appoints LD Stockholder Representative, LLC (the “Stockholder Representative”), and the Stockholder Representative xxxxxx accepts such appointment, as the true and lawful agent, proxy and attorney-in-fact of such Stockholder with full powers of substitution to act in the name, place and stead of such Stockholder with respect to the performance on behalf of such

106

Stockholder under the terms and provisions hereof and to do or refrain from doing all such further acts and things, and to execute all such documents, as the Stockholder Representative shall deem necessary or appropriate in connection with any transaction contemplated hereunder, including the power to:

(i) act for such Stockholder, if applicable, with respect to all indemnification matters referred to herein, including the right to compromise or settle any such claim on behalf of such Stockholder;

(ii) execute the Escrow Agreement on behalf of each Stockholder and act for such Stockholder with respect to the Escrow Amount (including giving any instructions to the Escrow Agent, on behalf of the Stockholders, to pay from the Escrow Fund any amounts owed by or to the Stockholders);

(iii) in its sole discretion, on behalf of the Stockholders, amend or waive any provision hereof in any manner;

(iv) employ, obtain and rely upon the advice of legal counsel (including Ropes & Gray LLP), accountants and other professional advisors as the Stockholder Representative, in its sole discretion, deems necessary or advisable in the performance of the duties of the Stockholder Representative;

(v) act for such Stockholder with respect to all Aggregate Closing Consideration matters and any other amounts payable to the Stockholders hereunder or in connection with any Ancillary Documents, including any adjustments thereto;

(vi) incur any expenses, liquidate and withhold assets received on behalf of such Stockholder prior to their distribution to such Stockholder to the extent of any amount that the Stockholder Representative deems necessary for payment of or as a reserve against expenses or other Liabilities, and pay such expenses or deposit the same in an interest-bearing bank account established for such purpose;

(vii) receive all notices, service of process, communications and deliveries hereunder on behalf of such Stockholder; and

(viii) do or refrain from doing any further act or deed on behalf of such Stockholder that the Stockholder Representative deems necessary or appropriate, in the sole discretion of the Stockholder Representative, relating to the subject matter hereof as fully and completely as such Stockholder could do if personally present and acting and as though any reference to such Stockholder herein was a reference to the Stockholder Representative.

(b) The appointment of the Stockholder Representative shall be deemed coupled with an interest and shall be irrevocable, and any other Person may conclusively and absolutely rely, without inquiry, upon any action of the Stockholder Representative as the act of each Stockholder in all matters referred to herein.

107

(c) In the event the Stockholder Representative resigns or ceases to function in such capacity for any reason whatsoever, then the successor Stockholder Representative shall be the Person that the Company’s majority Stockholder appoints.

(d) The Stockholder Representative is serving in that capacity solely for purposes of administrative convenience, and is not and shall not be personally liable in such capacity for any of the obligations of the Stockholders hereunder, and Xxxxxxxxx agrees that it will not assert claims against, or look to the personal assets of, the Stockholder Representative, acting in such capacity, for the satisfaction of any obligations to be performed by the Stockholders or the Company hereunder. The Stockholder Representative will not be liable for any act taken or omitted by it as permitted under this Agreement, except if such act is taken or omitted in bad faith or by willful misconduct. The Stockholder Representative will also be fully protected in relying upon any written notice, demand, certificate or document that it in good faith believes to be genuine (including facsimiles thereof). The Stockholders agree, severally but not jointly (in accordance with their Pro Rata Percentage), to indemnify the Stockholder Representative for, and to hold the Stockholder Representative harmless against, any loss, liability or expense incurred without willful misconduct or bad faith on the part of the Stockholder Representative, arising out of or in connection with the Stockholder Representative’s carrying out its duties under this Agreement, including costs and expenses of successfully defending itself against any claim of liability with respect thereto. The Stockholder Representative may consult with counsel of its own choice and will have full and complete authorization and protection for any action taken and suffered by it in good faith and in accordance with the opinion of such counsel.

(e) The Stockholder Representative represents and warrants that it is a Delaware limited liability company, duly formed, validly existing and in good standing under the laws of the State of Delaware and has all requisite limited liability company power and authority to carry on its business as now being conducted. The Stockholder Representative has all necessary limited liability company power and authority to execute and deliver this Agreement and the Escrow Agreement, to perform its obligations hereunder and thereunder and to consummate the transactions contemplated hereby and thereby. The execution and delivery of this Agreement and the Escrow Agreement by the Stockholder Representative, the performance by the Stockholder Representative of its obligations hereunder and thereunder, and the consummation of the transactions provided for herein and therein have been duly and validly authorized by all necessary action on the part of the Stockholder Representative. This Agreement has been, and the Escrow Agreement will be, duly executed and delivered by the Stockholder Representative, and constitutes, or will upon execution and delivery constitute, the valid and binding agreement of the Stockholder Representative, enforceable against the Stockholder Representative in accordance with its terms, except as such enforceability (i) may be limited by bankruptcy, insolvency, moratorium or other similar Laws affecting or relating to enforcement of creditors’ rights generally, and (ii) is subject to general principles of equity (regardless of whether enforceability is considered in a proceeding at Law or in equity). The execution and delivery of this Agreement does not, and the execution and delivery of the Escrow Agreement will not, and the performance of its obligations hereunder and thereunder will not, (i) conflict with or violate the certificate of formation

108

or LLC Agreement of the Stockholder Representative, or (ii) conflict with or violate any Law applicable to the Stockholder Representative (with or without notice or lapse of time or both), or by which any of the Stockholder Representative’s properties or assets is bound.

Section 11.15 Performance Guarantee. Parent Guarantor unconditionally and irrevocably agrees to take any and all actions necessary to cause Purchaser to perform all of its covenants, agreements and obligations under this Agreement, including with respect to the consummation of the Merger and the payment of consideration hereunder, indemnification and other obligations relating to or arising under ARTICLE III, ARTICLE VII, ARTICLE VIII, ARTICLE IX, ARTICLE X and ARTICLE XI hereof. Parent Guarantor unconditionally guarantees to the Company and the Stockholders the full and complete performance by Purchaser of such covenants, agreements and obligations and shall be liable for any breach by Purchaser of any such covenant, agreement or obligation. This is a guarantee of payment and performance. Parent Guarantor hereby waives diligence, presentment, demand of performance, filing of any claim, any right to require any proceeding first against Purchaser, protest, notice and all demands whatsoever in connection with the performance of its covenants, agreements and obligations as set forth in this Section 11.15.
