A Notice of

6

Termination submitted by the Company may provide for a Date of Termination on the date Executive receives the Notice of Termination, or any date thereafter elected by the Company in its sole discretion.

Any such prorated Annual Bonus shall be payable on the regularly scheduled payment date under the Company’s incentive bonus program (in the calendar year following the calendar year in which the Date of Termination occurs).

(a) New Stock Option. Promptly following the Effective Date, Executive shall be granted an option (the “Option”) to purchase 39,900 shares of Group common stock for an exercise price per share equal to the per share fair market value of Group’s common stock on the date of grant, as determined by Group’s board of directors.

(b) Acknowledgements and Agreements.

During Executive’s employment by the Company, Executive agrees that Executive will not violate any non-solicitation agreements Executive entered into with any former employer or improperly make use of, or disclose, any information or trade secrets of any former employer or other third party, nor will Executive bring onto the premises of the Company or use any unpublished documents or any property belonging to any former employer or other third party, in violation of any lawful agreements with that former employer or third party.

10

(c) Non-Competition/Non-Solicitation. Executive acknowledges and recognizes the highly competitive nature of the businesses of the Company, and further acknowledges and recognizes that the Company has entered into this Agreement in reliance on, among other things, Executive’s agreement to be bound by the non-competition provisions set forth in this Section 8(c). Accordingly, Executive agrees as follows:

(i) Executive shall not, at any time during the Term and the twelve (12) month period following the Date of Termination (or twenty-four (24) month period following the Date of Termination in the event of termination of Executive’s employment by the Company without Cause pursuant to Section 4(a)(iv) hereof or Executive’s Constructive Termination pursuant to Section 4(a)(v) hereof), directly or indirectly, (A) engage, participate or assist in any Competing Business, (B) enter the employ of, or render any services to, any Person engaged in any Competing Business, (C) acquire a financial interest in, or otherwise become actively involved with, any Person engaged in any Competing Business, whether as an individual, partner, shareholder, officer, director, principal, agent, trustee or consultant. Nothing herein shall prohibit Executive from being a passive owner of not more than two percent (2%) of the outstanding equity interest in any entity that is publicly traded, so long as Executive has no active participation in the business of such entity.

(ii) Executive hereby agrees that Executive shall not, at any time during the Term and the twelve (12) month period following the Date of Termination (or twenty-four (24) month period following the Date of Termination in the event of Executive’s termination of employment by the Company without Cause pursuant to Section 4(a)(iv) hereof or Executive’s Constructive Termination pursuant to Section 4(a)(v) hereof), directly or indirectly, either for himself or on behalf of any other Person, (A) recruit or otherwise solicit or induce any employee, customer or supplier of the Company to terminate its employment or arrangement with the Company, or otherwise change its relationship with the Company, or (B) hire, or cause to be hired, any Person who was employed by the Company at any time during the twelve (12)-month period immediately prior to the Date of Termination or who thereafter becomes employed by the Company.

(iii) In the event the terms of this Section 8(c) shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to, and may be modified by a court of competent jurisdiction to, extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action.

(iv) Executive understands that the restrictions set forth in this Section 8(c) are intended to protect the Company’s established employee, customer and supplier relations, and the general goodwill of its business, and Executive agrees that such restrictions are reasonable and appropriate for this purpose.

11

(v) Tolling. In the event Executive engages in conduct in violation of his covenants in Sections 8(c), the applicable restricted period shall be extended for a period of time equal to the time in which Executive engaged in competitive activity prohibited by this Agreement.

(d) Non-Disparagement. Each of the Parties agrees not to disparage the other party, any of the other’s products or practices, or any of the other’s agents, representatives, or Affiliates, either orally or in writing, at any time; provided, that either party may confer in confidence with their legal representatives and make truthful statements as required by law.

(e) Confidentiality. As used in this Agreement, “Confidential Information” means information belonging to the Company or any Affiliate which is of value to the Company or such Affiliate in the course of conducting its business and the disclosure of which could result in a competitive or other disadvantage to the Company or such Affiliate. Confidential Information includes, without limitation, patient or other medical information, financial information, reports, forecasts, inventions, improvements and other intellectual property, trade secrets, know-how, designs, processes or formulae, software, market or sales information or plans, customer lists, business plans and prospects and opportunities (such as possible acquisitions or dispositions of businesses or facilities) which have been discussed or considered by the management of the Company. Confidential Information also includes information developed by Executive in the course of Executive’s employment by the Company, as well as other information to which Executive may have access in connection with Executive’s employment. Confidential Information also includes the confidential information of others with which the Company or any Affiliate has a business relationship and which is known by Executive or which Executive should have reason to know about. Notwithstanding the foregoing, Confidential Information does not include information in the public domain, unless due to breach of Executive’s duties under this Section 8(e).

(i) Executive understands and agrees that Executive’s employment creates a relationship of confidence and trust between Executive and the Company with respect to all Confidential Information. At all times, both during Executive’s employment with the Company and after its termination, Executive will keep in confidence and trust all such Confidential Information, and will not use or disclose any such Confidential Information without the written consent of the Company, except as may be necessary in the ordinary course of performing Executive’s duties to the Company or as otherwise required by law.

(ii) All documents, records, data, apparatus, equipment and other physical property, whether or not pertaining to Confidential Information, which are furnished to Executive by the Company or any Affiliate or are produced by Executive in connection with Executive’s employment will be and remain the sole property of the Company. Executive will return to the Company all such materials and property as and when requested by the Company. In any event, Executive will return all such materials and property immediately upon termination of Executive’s employment for any reason, and will not retain any copies thereof following such termination.

12

It is recognized and acknowledged by Executive that a breach of the covenants contained in Section 8 will cause irreparable damage to Company and its goodwill, the exact amount of which will be difficult or impossible to ascertain, and that the remedies at law for any such breach will be inadequate.

15

(l) Withholding. The Company shall be entitled to withhold from any amounts payable under this Agreement any federal, state, local or foreign withholding or other taxes or charges which the Company is required to withhold. The Company shall be entitled to rely on an opinion of counsel if any questions as to the amount or requirement of withholding shall arise.

(a) General. The intent of the Parties is that the payments and benefits under this Agreement comply with or be exempt from Section 409A and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. If Executive notifies the Company that Executive has received advice of tax counsel of a national reputation with expertise in Section 409A that any provision of this Agreement would cause Executive to incur any additional tax or interest under Section 409A (with specificity as to the reason therefor) or the Company (which shall have no obligation to assess the issue absent such notice from Executive) independently makes such determination, the Company and Executive shall take commercially reasonable efforts to reform such provision to try to comply with or be exempt from Section 409A through good faith modifications to the minimum extent reasonably appropriate to conform with Section 409A, provided that any such modifications shall not increase the cost or liability to the Company. To the extent that any provision hereof is modified in order to comply with or be exempt from Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to Executive and the Company of the applicable provision without violating the provisions of Section 409A. Notwithstanding anything herein to the contrary, Executive acknowledges and agrees that (i) Executive is not relying upon any determination by the Company, its Affiliates, or any of their respective employees, directors, officers, attorneys or agents regarding the tax effects, including, without limitation, tax effects under Section 409A, associated with Executive’s entry into this Agreement or the receipt of any payments hereunder, and (ii) in deciding to enter into this Agreement, Executive is relying on Executive’s own judgment and the judgment of the professionals of Executive’s choice with whom Executive has consulted.

(b) Separation from Service. Notwithstanding any provision to the contrary in this Agreement: (i) no amount that constitutes “deferred compensation” under Section 409A shall be payable pursuant to Sections 5(b) or 5(c) unless the termination of Executive’s employment constitutes a “separation from service” within the meaning of Section 1.409A-1(h) of the Department of Treasury Regulations (“Separation from Service”); (ii) for purposes of Section 409A, Executive’s right, if any, to receive installment payments pursuant to Sections 5(b) or 5(c) hereof shall be treated as a right to receive a series of separate and distinct payments; and (iii) to the extent that any reimbursement of expenses or in-kind benefits constitutes “deferred compensation” under Section 409A, such reimbursement or benefit shall be provided no later than December 31^st of the year following the year in which the expense was incurred. The amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year. The amount of any in-kind benefits provided in one year shall not affect the amount of in-kind benefits provided in any other year. Any good faith determination by the Company in respect of Section 409A shall be final and binding on Executive.

16

(c) Specified Employee. Notwithstanding anything in this Agreement to the contrary, if Executive is deemed by the Company at the time of Executive’s Separation from Service to be a “specified employee” for purposes of Section 409A, to the extent delayed commencement of any portion of the benefits to which Executive is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A, such portion of Executive’s benefits shall not be provided to Executive prior to the earlier of (i) the expiration of the six (6)-month period measured from the date of Executive’s Separation from Service with the Company or (ii) the date of Executive’s death. Upon the first business day following the expiration of the applicable Section 409A period, all payments deferred pursuant to the preceding sentence shall be paid in a lump sum to Executive (or Executive’s estate or beneficiaries), and any remaining payments due to Executive under this Agreement shall be paid as otherwise provided herein.

(d) Release. Notwithstanding anything to the contrary in this Agreement, to the extent that any payments due under this Agreement as a result of termination of Executive’s employment are subject to Executive’s execution and delivery of a Release, (i) if Executive fails to execute and deliver the Release on or prior to the Release Deadline (as defined below) or timely revokes the Release thereafter, Executive shall not be entitled to any payments or benefits otherwise conditioned on the Release, and (ii) in any case where the Date of Termination and the Release Deadline fall in two separate taxable years, any payments required to be made to Executive that are conditioned on the Release and are treated as nonqualified deferred compensation for purposes of Section 409A shall be made in the later taxable year. For purposes of this Section 12(d), “Release Deadline” shall mean the date that is twenty-one (21) days following the date upon which the Company timely delivers the Release to Executive, or, in the event that Executive’s termination of employment is “in connection with an exit incentive or other employment termination program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967), as determined by the Company, the date that is forty-five (45) days following such delivery date. To the extent that any payments of nonqualified deferred compensation (within the meaning of Section 409A) due under this Agreement as a result of Executive’s termination of employment are delayed pursuant to this Section 12(d), such amounts shall be paid in a lump sum on the first payroll date following the date that Executive executes and delivers and does not revoke the Release (and the applicable revocation period has expired) or, in the case of any payments subject to Section 12(d)(iii), on the first payroll period to occur in the subsequent taxable year, if later.

(a) Best Pay Cap. Notwithstanding any other provision of this Agreement, in the event that any payment or benefit received or to be received by Executive (including any payment or benefit received in connection with a termination of Executive’s employment, whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement) (all such payments and benefits, including the payments and benefits under Section 5 hereof, being hereinafter referred to as the “Total Payments”) would be subject (in whole or part), to the excise tax imposed under Section 4999 of the Code (such excise tax, the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Code in such other plan, arrangement or agreement, the cash severance payments under this Agreement shall first be reduced, and the noncash severance payments hereunder shall thereafter be reduced, to the extent necessary so that no portion of the Total Payments is subject

17

to the Excise Tax but only if (i) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments) is greater than or equal to (ii) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which Executive would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments).

(b) Certain Exclusions. For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (i) no portion of the Total Payments the receipt or enjoyment of which Executive shall have waived at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be taken into account; (ii) no portion of the Total Payments shall be taken into account which, in the written opinion of an independent, nationally recognized accounting firm selected by the Company (the “Independent Advisors”), does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall be taken into account which, in the opinion of Independent Advisors, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the “base amount” (as defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation; and (iii) the value of any non cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Independent Advisors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code. Promptly following any request to do so, Executive shall provide to any Independent Advisors such information as they may require to assess the impact of Section 280G(b) on any amounts payable hereunder. Any good faith determinations of the Independent Advisors made hereunder shall be final and binding upon the Company and Executive.

Executive acknowledges that Executive has read and understands this Agreement, is fully aware of its legal effect, has not acted in reliance upon any representations or promises made by the Company other than those contained in writing herein, and has entered into this Agreement freely based on Executive’s own judgment.
