(c) No Bonus shall be paid for any period after the termination of the Executive’s employment; provided, however, a Pro-Rated Bonus (as defined below) shall be payable to the Executive for the year of termination through the date of termination to the extent set forth in Sections 7.2 and 7.3 below.

5.4. Expenses. The Company will reimburse the Executive for all reasonable and necessary expenses incurred by the Executive in connection with the business of the ARH Group (“Expenses”), provided that such expense reimbursements are in accordance with applicable policies of the Company in effect from time to time and are properly documented and accounted.

5.5. Insurance; Indemnification. Throughout the Term of this Agreement and for a period of 12 months following the effective date of the Executive’s termination from the Company’s employment, the Company or ARH agrees to maintain director and officer liability insurance for the benefit of the Executive in scope and amounts reasonably acceptable to the Board. Executive shall be entitled to indemnification under ARH’s charter and bylaws or other indemnification agreement as they exist from time to time, but always on a basis consistent with the terms applicable from time to time for members of the Board.

5.6. Company’s Life Insurance. The Company, in its sole discretion, may apply for and procure in its own name (whether or not for its own benefit) policies of insurance insuring the life of Executive in such amounts as Company may deem advisable. Executive shall have no right, title or interest in any such policies of insurance, except to the extent his estate or other persons are specifically named as beneficiaries thereof.

Accordingly, and in consideration of the mutual promises contained herein, and in order to protect the goodwill and going concern value of the ARH Group, the Executive agrees to the covenants set forth below. As used herein, “Restrictive Period” means the period beginning on the Effective Date and ending on the third (3^rd) anniversary of the effective date of the termination of the Executive’s employment with the Company, however such termination may occur; provided, however, that, solely in the case of a Change in Control, “Restrictive Period” shall mean the period beginning on the Effective Date and ending on the later of (i) the third (3^rd) anniversary of the Change in Control and (ii) the first (1^st) anniversary of the effective date of Executive’s termination; provided further that, solely in the case of a Change in Control, the Company shall have the right to extend the Restrictive Period by delivery of written notice to the Executive (the “Election Notice”) until the later of (i) the fifth (5^th) anniversary of the Change in Control and (ii) the first (1^st) anniversary of the effective date of Executive’s termination.

The Executive agrees that at all times during his employment and thereafter (including periods after the term of this Agreement), he will keep and maintain all Confidential Information and all of the affairs of the ARH Group and its Affiliates confidential, and will not, except (i) as necessary for the performance of his responsibilities hereunder or (ii) as required by judicial process and after prior notice to the Company (as early as practicable, and in any event not less than three (3) days prior to any such required disclosure), unless required earlier by a court order or a legal requirement, disclose to any person for any reason or purpose whatsoever, directly or indirectly, all or any part of the Confidential

- 7 -

Information of the ARH Group and its Affiliates. The Executive is not bound by the restrictions in this paragraph with respect to any information that becomes public other than as a consequence of the breach by the Executive of his confidentiality obligations hereunder or is disclosed without an obligation of confidentiality. The Executive can disclose all information to his personal advisors, in the context of seeking advice regarding employment hereunder, subject to becoming liable for any violation by them of the Executive’s confidentiality obligations. The Executive agrees that on the termination of his employment, however such termination may occur, the Executive will promptly return to the Company all materials and other property from time to time held by the Executive and proprietary to the ARH Group including without limitation any documents incorporating, reflecting or reproducing in whole or in part any Confidential Information, credit cards, and the like.

8.1.4. During the Restrictive Period, the Executive will not, directly or indirectly, compete with the Company and/or its Affiliates as an owner, partner, member, shareholder, consultant, agent, employee, director or co-venturer of any business (i) engaged in the kidney dialysis business and/or the operation of kidney dialysis facilities within 10 miles of any such facility owned and operated by the ARH Group, (ii) engaged in the kidney dialysis business and/or the operation of kidney dialysis facilities where the Executive is involved in a program to establish joint ventures with nephrologists in the United States of America, and (iii) in the case of a termination of employment that occurs on or before the third anniversary of the Effective Date or which occurs after a Change in Control, engaged in the kidney dialysis business and/or the operation of kidney dialysis facilities in the United States of America.

- 8 -

8.3. Enforcement; Remedies. The Executive covenants, agrees and recognizes that because the breach or threatened breach of the covenants, or any of them, contained in Section 8.1 hereof will result in immediate and irreparable injury to the ARH Group, the ARH Group shall be entitled to an injunction restraining the Executive from any violation of Section 8.1 to the fullest extent allowed by law. The Executive further covenants and agrees that in the event of a violation of any of the respective covenants and agreements contained in Section 8.1 hereof, (i) the ARH Group shall be entitled to receive all such amounts to which the ARH Group would be entitled as damages under law or at equity and (ii) upon the ARH Group obtaining a judgment or an injunction from a court of competent jurisdiction, the obligations of the ARH Group to make any further payments to Executive pursuant to any provision of this Agreement shall be suspended until Executive shall cease violating or breaching his respective covenants and agreements contained in Section 8.1 hereof and the ARH Group shall have received reasonable assurances from Executive that he will no longer engage in the same at which time the previously suspended payments shall be made to Executive. Nothing herein shall be construed as prohibiting the ARH Group from pursuing any other legal or equitable remedies that may be available to it for any such breach, including the recovery of damages from the Executive. The prevailing party in any action relating to a violation or alleged violation of any on the of the respective covenants and agreements contained in Section 8.1 hereof shall be entitled to receive for the other party, and such other party shall pay to the prevailing party, its reasonable and documented costs and expenses associated with such action.

(i) the covenants set forth in Article 8 are reasonable in all respects and are necessary to protect the legitimate business and competitive interests of the ARH Group in connection with their business which the Executive agrees, pursuant to this Agreement, to assist in maintaining and developing; and

(ii) each of the covenants set forth in Article 8 is separately and independently given, and each such covenant is intended to be enforceable separately and independently of the other such covenants, including without limitation, enforcement by injunction, and that the invalidity or unenforceability of any provision of this Agreement in any respect shall not affect the validity or enforceability of this Agreement in any other respect.

In the event that any provision of this Agreement shall be held invalid or unenforceable by a court of competent jurisdiction by reason of the geographic or business scope or the duration thereof of any such covenant, or for any other reason, such invalidity or unenforceability shall attach only to the particular aspect of such provision found invalid or unenforceable as applied and shall not affect or render invalid or unenforceable any other provision. This Agreement shall be construed as if the geographic or business scope or the duration of such provision or other basis on which such provisions has been challenged had been more narrowly drafted so as not to be invalid or unenforceable. The provisions under Article 8 shall survive the termination of the Executive’s employment for any reason.

ARTICLE 9

MISCELLANEOUS

Except with respect to controversies or claims arising under Article 8 hereof, the Executive and the Company shall submit to mandatory binding arbitration in any controversy or claim arising out of, or relating to, this Agreement or any breach hereof. Such arbitration shall be conducted in Boston, Massachusetts in accordance with the employment rules of the American Arbitration Association in effect at the time such arbitration is conducted, and judgment upon the determination or award rendered by the arbitrator may be entered in any court having jurisdiction thereof.

- 9 -

9.2. Absence of Conflicting Agreements and Obligations. The Executive represents and warrants that he is not a party to or bound by any other agreement or understanding of any type, whether written or oral, or by any statutory or common law duty or obligation which, in any case, would in any way restrict his ability to be employed by the Company, or his ability to compete freely with any other Person.

9.3. Severability. If any provision of this Agreement shall be found by any arbitrator or court of competent jurisdiction to be invalid or unenforceable, then the parties hereby waive such provision to the extent that it is found to be invalid or unenforceable and to the extent that to do so would not deprive one of the parties of the substantial benefit of its bargain. Such provision shall, to the extent allowable by law and the preceding sentence, be modified by such arbitrator or court so that it becomes enforceable and, as modified, shall be enforced as any other provision hereof, all the other provisions continuing in full force and effect.

9.4. No Waiver. The failure by either party at any time to require performance or compliance by the other of any of its obligations or agreements shall in no way affect the right to require such performance or compliance at any time thereafter. The waiver by either party of a breach of any provision hereof shall not be taken or held to be a waiver of any preceding or succeeding breach of such provision or as a waiver of the provision itself. No waiver of any kind shall be effective or binding, unless it is in writing and is signed by the party against whom such waiver is sought to be enforced.

9.5. Assignment. This Agreement and all rights hereunder are personal to the Executive and may not be transferred or assigned by the Executive at any time.

9.13. Compliance with IRC Section 409A.

(a) Notwithstanding anything herein to the contrary, (i) if at the time of the Executive’s termination of employment with the Company Executive is a “specified employee” as defined in Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent any accelerated or additional tax under Section 409A of the Code, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such payments or benefits ultimately paid or provided to Executive) until the date that is six months following Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A of the Code without any accelerated or additional tax) and (ii) if any other payments of money or other benefits due to Executive hereunder could cause the application of an accelerated or additional tax under Section 409A of the Code, such payments or other benefits shall be deferred if deferral will make such payment or other benefits compliant under Section 409A of the Code, or otherwise such payment or other benefits shall be restructured, to the extent possible, in a manner, determined by the Board, that is reasonably expected not to cause such an accelerated or additional tax. Any payment or benefit delayed by reason of the prior sentence shall be paid out or provided in a single lump sum at the end of such required delay period in order to catch up to the original payment schedule.

(b) For purposes of Section 409A of the Code, each payment made under this Agreement shall be designated as a “separate payment” within the meaning of Section 409A of the Code, any series of installment payments under this Agreement shall be treated as a right to a series of separate payments, and references herein to Executive’s “termination of employment” shall refer to Executive’s separation from service with the Company within the meaning of Section 409A of the Code.

(c) (i) Any reimbursements by the Company to the Executive of any eligible expenses under this Agreement that are not excludable from the Executive’s income for Federal income tax purposes (the “Taxable Reimbursements”) shall be made by no later than the earlier of the date on which they would be paid under the Company’s normal policies and the last day of the taxable year of the Executive following the year in which the expense was incurred.

(ii) The amount of any Taxable Reimbursements, and the value of any in-kind benefits to be provided to the Executive, during any taxable year of the Executive shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year of the Executive (except for any life-term or other aggregate limitation applicable to medical expenses).

(iii) The right to Taxable Reimbursement, or in-kind benefits, shall not be subject to liquidation or exchange for another benefit.

(d) Notwithstanding any other provisions of this Agreement or any other agreement to which the Company and the Executive are parties to the contrary, in no event shall any payment under this Agreement that constitutes “deferred compensation” for purposes of Section 409A of the Code be subject to offset by any other amount unless otherwise permitted by Section 409A of the Code.
