3

outstanding shares of common stock of the Parent (the “Outstanding Parent Common Stock”) or the combined voting power of the then-outstanding securities of the Parent entitled to vote generally in the election of directors (the “Outstanding Parent Voting Securities”); provided, however, that for purposes of this subsection (a), the following acquisitions shall not constitute a Change in Control: (1) any acquisition of more than 50% of the Outstanding Parent Common Stock directly from the Company (excluding an acquisition pursuant to the exercise, conversion or exchange of any security exercisable for, convertible into or exchangeable for common stock or voting securities of the Company, unless the Person exercising, converting or exchanging such security acquired such security directly from the Company or an underwriter or agent of the Company); (2) any acquisition of more than 50% of the Outstanding Parent Common Stock by the Company; (3) any acquisition of more than 50% of the Outstanding Parent Common Stock by any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company; or (4) any acquisition by any Person who, prior to such acquisition, already owned more than 33% of the Outstanding Parent Common Stock or Outstanding Parent Voting Securities; or (ii) the consummation of a merger, consolidation, reorganization, recapitalization or statutory share exchange involving the Parent or a sale or other disposition of all or substantially all of the assets of the Company in one or a series of transactions (a “Business Combination”), unless, immediately following such Business Combination, all or substantially all of the individuals and entities who were the beneficial owners of the Outstanding Parent Common Stock and Outstanding Parent Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of the then-outstanding shares of common stock and the combined voting power of the then-outstanding securities entitled to vote generally in the election of directors, respectively, of the resulting or acquiring corporation in such Business Combination (which shall include, without limitation, a corporation which as a result of such transaction owns the Company or substantially all of the Company’s assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Business Combination, of the Outstanding Parent Common Stock and Outstanding Parent Voting Securities, respectively.

6. Additional Covenants of the Executive.

6.1 Noncompetition; Nonsolicitation; Nondisparagement.

(a) During Executive’s employment with the Company, Executive shall not, directly or indirectly, render services of a business, professional or commercial nature to any other person or entity that competes with the Company’s business, whether for compensation or otherwise, or engage in any business activities competitive with the Company’s business, whether alone, as an Executive, as a partner, or as a shareholder (other than as the holder of not more than one percent of the combined voting power of the outstanding stock of a public company), officer or director of any corporation or other business entity, or as a trustee, fiduciary or in any other similar representative capacity of any other entity. Notwithstanding the foregoing, the expenditure of reasonable amounts of time as a member of other companies’ Board of Directors shall not be deemed a breach of this if those activities do not materially interfere with the services required under this Agreement.

(b) During Executive’s employment with the Company, and for a period of one year following the termination of the Executive’s employment with the Company, the Executive shall not, without the prior written consent of the Company:

(i) either individually or on behalf of or through any third party, directly or indirectly, solicit, entice or persuade or attempt to solicit, entice or persuade any employee, agent, consultant or contractor of the Company or any of its affiliates (the “Company Group”) to leave the service of the Company Group for any reason; or

(ii) either individually or on behalf of or through any third party, directly or indirectly, interfere with, or attempt to interfere with, the business relationship between the Company Group and any vendor, supplier, surgeon or hospital with which the Executive has interacted during the course of Executive’s employment with the Company.

(c) During Executive’s employment with the Company and at all times thereafter, Executive shall not make any statements that are professionally or personally disparaging about, or adverse to, the interests of the Company or any of its divisions, affiliates, subsidiaries or other related entities, or their respective directors, officers, employees, agents, successors and assigns (collectively, “Company-Related Parties”), including, but not limited to, any statements that disparage any person, product, service, finances, financial condition, capability or any other aspect of the business of any Company-Related Party, and that Executive will not engage in any conduct which could reasonably be expected to harm professionally or personally the reputation of any Company-Related Party.

6.2 If any restriction set forth in this Section 6 is found by any court of competent jurisdiction to be unenforceable because it extends for too long a period of time or over too great a range of activities or in too broad a geographic area, it shall be interpreted to extend only over the maximum period of time, range of activities or geographic area as to which it may be enforceable.

6.3 The restrictions contained in this Section 6 are necessary for the protection of the confidential, nonpublic information relating to the Company and its operations, strategies, development plans, financial information and other proprietary corporate information, and are considered by Executive to be reasonable for such purpose. Executive agrees that any breach of this Section 6 will cause the Company substantial and irrevocable damage and therefore, in the event of any such breach, in addition to such other remedies which may be available, the Company shall have the right to seek specific performance and injunctive relief.

7. Other Agreements. Executive represents that Executive’s performance of all the terms of this Agreement as an Executive of the Company does not and will not breach any (i) agreement to keep in confidence proprietary information, knowledge or data acquired by Executive in confidence or in trust prior to Executive’s employment with the Company or (ii) agreement to refrain from competing, directly or indirectly, with the business of any previous employer or any other party.

8. Notices. All notices required or permitted under this Agreement shall be in writing and shall be deemed effective upon (i) a personal delivery, or (ii) deposit in the United States Post Office, by registered or certified mail, postage prepaid.

10. Amendment. This Agreement may be amended or modified only by a written instrument executed by both the Company and Executive.

11. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of both parties and their respective successors and assigns, including any corporation into which the Company may be merged or which may succeed to its assets or business, provided, however, that the obligations of Executive are personal and shall not be assigned by Executive. The Company may assign this Agreement following the delivery of written notice to the Executive.

12. Miscellaneous.

12.1 No Waiver. No delay or omission by the Company in exercising any right under this Agreement shall operate as a waiver of that or any other right. A waiver or consent given by the Company on any one occasion shall be effective only in that instance and shall not be construed as a bar or waiver of any right on any other occasion.

12.2 Severability. In case any provision of this Agreement shall be invalid, illegal or otherwise unenforceable, the validity, legality and enforceability of the remaining provisions shall in no way be affected or impaired thereby.
