WHEREAS, the Company desires to employ the Executive as its President and Chief Executive Officer and the Executive desires to accept such employment, on the terms set forth below.

Accordingly, the parties hereto agree as follows:

1. Term. The Company hereby employs the Executive, and the Executive hereby accepts such employment for an initial term commencing as of the date hereof and ending December 31 , 2010, unless sooner terminated in accordance with the provisions of Section 4 or Section 5 (the period during which the Executive is employed hereunder being hereinafter referred to as the “Term”). If either the Company or Executive does not wish to renew this Agreement when it expires at the end of the initial or any renewal term hereof as hereinafter provided, or if either the Company or Executive wishes to renew this Agreement on different terms than those contained herein, it or he shall give written notice in accordance with Section 10.4 below of such intent to the other party at least one hundred twenty (120) days prior to the expiration date. In the absence of such notice, this Agreement shall be renewed on the same terms and conditions contained herein for a term of one (1) year from the date of expiration. The parties expressly agree that designation of a term and renewal provisions in this Agreement does not in any way limit the right of the parties to terminate this Agreement at any time as hereinafter provided. Reference herein to the term of this Agreement shall refer both to the initial term and any successive term as the context requires.

2. Duties. The Executive, in his capacity as President and Chief Executive, shall faithfully perform for the Company the duties of said office and shall perform such other duties consistent with his position of an executive, managerial or administrative nature as shall be specified and designated from time to time by the Company’s board of directors or similar governing body of the Company (the “Board”) (including the performance of services for, and serving on the Board of Directors of, any subsidiary or affiliate of the Company without any additional compensation). In addition, for so long as Executive remains President and Chief Executive Officer of the Company, the Board shall nominate him as a member of the Board of Directors of the Company (the “Board) and shall use its best efforts to cause his election as a Member of the Board. The Executive shall devote substantially all of the Executive’s business time and effort to the performance of the Executive’s duties hereunder, provided that in no event shall this sentence prohibit the Executive from performing personal, investment and charitable

activities and any other activities, including serving on the board of directors of other companies, provided, however, that the Executive may serve on the board of directors of Z-KAT, Inc. only if approved by a majority of the disinterested members of the Board, so long as such activities do not materially and adversely interfere with the Executive’s duties for the Company. The Board may delegate its authority to take any action under this Agreement to the Compensation Committee of the Board (the “Compensation Committee”).

3. Compensation.

3.1 Salary. The Company shall pay the Executive during the Term an Annual Salary at the rate of three hundred thousand dollars ($300,000) per annum (the “Annual Salary”), payable semi-monthly and subject to regular deductions and withholdings as required by law.

3.2 Annual Cash Incentive. The Executive’s target Annual Cash Incentive amount will be 50% of the Annual Salary then in effect for each applicable year, provided, however, that Executive’s Annual Cash Incentive, if any, may be below, at, or above the target based upon the achievement of individual and objective Company annual performance criteria established by the Compensation Committee, in its discretion. The Annual Cash Incentive will be paid within 2 ¹/2 months after the end of the calendar year to which the Annual Cash Incentive relates.

3.6 Equity Awards in the Event of a Change in Control.

5.2 Termination by Executive Other Than For Good Reason. Executive may terminate his employment hereunder voluntarily for reasons other than Good Reason (as defined in Section 6.5) at any time upon at least 30 days’ written notice to the Company. An election by Executive not to extend the Term pursuant to Section 2 hereof shall be deemed to be a termination of employment by Executive for reasons other than Good Reason at the date of expiration of the Term. At the time Executive’s employment is terminated by Executive other than for Good Reason, the Term will terminate, all obligations of the Company and Executive under Sections 1 through 3 will immediately cease, and the Company will pay Executive, and Executive will be entitled to the same compensation and rights specified in Section 5.1.

5.3 Termination by the Company Without Cause. The Company may terminate the employment of Executive hereunder without Cause upon at least 30 days’ written notice to Executive. An election by the Company not to extend the Term pursuant to Section 2 hereof shall be deemed to be a termination of employment by the Company Without Cause at the date of expiration of the Term. At the time Executive’s employment is terminated by the Company (i.e., at the expiration of such notice period), the Term will terminate, all remaining obligations of the Company and Executive under Sections 1 through 3 will immediately cease (except as expressly provided below), and the Company will pay Executive, and Executive will be entitled to receive, the following:

	(i)		Executive’s Compensation Accrued at Termination;

	(ii)		A single severance payment in cash in an aggregate amount equal to the sum of: (i) one (1) times the Executive’s Annual Salary plus (ii) one (1) times the average of the two highest Annual Cash Incentive received by Executive during the preceding three completed performance years provided, however, that if such termination shall occur in anticipation of a Change in Control (as defined in Section 6.2) or on or within two (2) years after a Change in Control, such severance payment shall be two (2) times the Executive’s Annual Salary and average Annual Cash Incentive;

	(iii)		In lieu of any annual incentive compensation under Section 3.2 for the year in which Executive’s employment terminates, a Partial Year Bonus (as defined in Section 6.6);

	(iv)		All equity awards held by Executive at termination which vest based on time shall become vested and all other terms of such awards shall be governed by the plans and programs and the agreements and other documents pursuant to which such options were granted;

	(v)		Any performance objectives upon which the earning of performance-based restricted stock, RSUs, and other equity awards and other long-term incentive awards (including cash awards,) is conditioned shall be deemed to have been met at the greater of (A) target level at the date of termination, or (B) actual performance at the date of termination, and such amounts shall become fully vested and non-forfeitable as a result of termination of employment at the date of such termination, and, in other respects, such awards shall be governed by the plans and programs and the agreements and other documents pursuant to which such awards were granted; and

	(vi)		All other rights under any other compensatory or benefit plan shall be governed by such plan. In addition, at Company’s expense, Executive and his spouse and dependent children shall be entitled to continuation of health insurance coverage (i.e., medical, dental and vision) under the Company’s group health plan(s) in which the Executive was participating on the date of termination or if such plan(s) have been terminated, in the plan(s) in which senior executives of the Company participate for a period of one (1) year after the date Executive’s employment terminates.

Payments and benefits under this Section 5.3 are subject to Section 5.6.

5.4 Termination by Executive for Good Reason. Executive may terminate his employment hereunder for Good Reason upon 30 days’ written notice to the Company which notice must be given within 90 days of the occurrence of the condition that is the basis for such Good Reason; provided, however, that, if the basis for such Good Reason is correctible and the Company has corrected the basis for such Good Reason within 30 days after receipt of such notice, Executive may not then terminate his employment for Good Reason with respect to the matters addressed in the written notice, and therefore Executive’s notice of termination will automatically become null and void. At the time Executive’s employment is terminated by Executive for Good Reason (i.e., at the expiration of such notice period), the Term will terminate, all obligations of the Company and Executive under Sections 1 through 3 will immediately cease (except as expressly provided below), and the Company will pay Executive, and Executive will be entitled to receive, the same compensation and rights specified in Section 5.3(i) — (vi) and the text following clause (vi).

If any payment or benefit under this Section 5.4 is based on Annual Salary or other level of compensation or benefits at the time of Executive’s termination and if a reduction in such Annual Salary or other level of compensation or benefit was the basis for Executive’s termination for Good Reason, then the Annual Salary or other level of compensation in effect before such reduction shall be used to calculate payments or benefits under this Section 5.4.

5.5 Other Terms Relating to Certain Terminations of Employment. In the event Executive’s employment terminates for any reason set forth in Section 5.2 through 5.4, Executive will be entitled to the benefit of any terms of plans or agreements applicable to Executive which are more favorable than those specified in this Section 5 (except without duplication of payments or benefits, including in the case of the Annual Cash Incentive in lieu of which amounts are paid hereunder). Except as otherwise provided under Section 5.6, amounts payable under this Section 5 following Executive’s termination of employment, other than those expressly payable on a deferred or installment basis, will be paid as promptly as practicable after such a termination of employment and, in any event, within 2 ¹/2 months after the end of the year in which employment terminates.

5.6 Limitations Under Code Section 409A. Anything in this Agreement to the contrary notwithstanding, if (A) on the date of termination of Executive’s employment with the Company or a Subsidiary, any of the Company’s stock is publicly traded on an established securities market or otherwise (within the meaning of Section 409A(a)(2)(B)(i) of the Internal Revenue Code, as amended (the “Code”)), (B) if Executive is determined to be a “specified employee” within the meaning of Section 409A(a)(2)(B) of the Code, (C) the payments exceed the amounts permitted to be paid pursuant to Treasury Regulations section 1.409A-1(b)(9)(iii) and (D) such delay is required to avoid the imposition of the tax set forth in Section 409A(a)(1) of the Code, as a result of such termination, the Executive would receive any payment that, absent the application of this Section 5.6, would be subject to interest and additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, then no such payment shall be payable prior to the date that is the earliest of (1) six (6) months after the Executive’s termination date, (2) the Executive’s death or (3) such other date as will cause such payment not to be subject to such interest and additional tax (with a catch-up payment equal to the sum of all amounts that have been delayed to be made as of the date of the initial payment).

It is the intention of the parties that payments or benefits payable under this Agreement not be subject to the additional tax imposed pursuant to Section 409A of the Code. To the extent such potential payments or benefits could become subject to such Section, the parties shall cooperate to amend this Agreement with the goal of giving the Executive the economic benefits described herein in a manner that does not result in such tax being imposed.

6.1 “Cause”. For purposes of this Agreement, “Cause” shall mean Executive’s:

	(i)		conviction for commission of a felony or a crime involving moral turpitude;

willful and continued failure to substantially perform Executive’s duties hereunder (other than such failure resulting from Executive’s incapacity due to physical or mental illness), which failure is not remedied within 30 calendar days after written demand for substantial performance is delivered by the Company which specifically identifies the manner in which the Company believes that Executive has not substantially performed Executive’s duties.

No act, or failure to act, on the part of Executive shall be deemed “willful” unless done, or omitted to be done, by Executive not in good faith and without reasonable belief that his action or omission was in the best interest of the Company.

(iv)

The Company’s stockholders approve a liquidation or dissolution of the Company and all material contingencies to such liquidation or dissolution have been satisfied or waived.

This definition shall be interpreted and applied consistent with the Americans with Disabilities Act, the Family and Medical Leave Act, Section 409A of the Code and other applicable law.

6.5 “Good Reason”. For purposes of this Agreement, “Good Reason” shall mean, without Executive’s express written consent, the occurrence of any of the following circumstances unless, if correctable, such circumstances are fully corrected within 30 days of the notice of termination given in respect thereof:

7. Excise Tax-Related Provisions. In the event Executive becomes entitled to any amounts or benefits payable in connection with a Change in Control or other change in control (whether or not such amounts are payable pursuant to this Agreement) (the “Severance Payments”), if any of such Severance Payments are subject to the tax (the “Excise Tax”) imposed by Section 4999 of the Code (or any similar federal, state or local tax that may hereafter be imposed), the Company shall pay to Executive at the time specified in Section 7(iii) hereof an additional amount (the “Gross-Up Payment”) such that the net amount retained by Executive, after deduction of any Excise Tax on the Total Payments (as hereinafter defined) and any federal, state and local income tax and Excise Tax upon the payment provided for by Section 7(i), shall be equal to the Total Payments; provided, however that in the event the aggregate value of the Total Payments exceeds three times the Executive’s “base amount,” as defined in Section 280G(b)(3) of the Code, (the “Parachute Threshold”) by less than 10%, one or more of the Total Payments shall be reduced so that the aggregate value of the Total Payments is $1.00 less than the Parachute Threshold. Unless the Executive shall have given prior written notice specifying a

different order to the Company to effectuate the foregoing, the Company shall reduce or eliminate the Total Payments by first reducing or eliminating the portion of the Total Payments which are not payable in cash and then by reducing or eliminating cash payments, in each case in reverse order beginning with payments or benefits which are to be paid the farthest in time from the Change in Control. Any notice given by the Executive pursuant to the preceding sentence shall take precedence over the provisions of any other plan, arrangement or agreement governing the Executive’s rights and entitlements to any benefits or compensation. For the avoidance of doubt, in no event shall the Company be required to pay to Executive any amount under this Section 7 with respect to any taxes or interest that may arise as a result of Section 409A of the Code.

(i)

For purposes of determining whether any of the Severance Payments will be subject to the Excise Tax and the amount of such Excise Tax:

	(A)		any other payments or benefits received or to be received by Executive in connection with a Change in Control or Executive’s termination of employment (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, any Person whose actions result in a Change in Control or any Person affiliated with the Company or such Person) (which, together with the Severance Payments, constitute the “Total Payments”) shall be treated as “parachute payments” within the meaning of Section 280G(b)(2) of the Code, and all “excess parachute payments” within the meaning of Section 280G(b)(1) of the Code shall be treated as subject to the Excise Tax, unless in the opinion of nationally-recognized tax counsel or compensation consultant the selection of which was approved under Section 7(iv) such other payments or benefits (in whole or in part) do not constitute parachute payments, or such excess parachute payments (in whole or in part) represent reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4) of the Code in excess of the base amount within the meaning of Section 280G(b)(3) of the Code, or are otherwise not subject to the Excise Tax;

	(B)		the amount of the Total Payments which shall be treated as subject to the Excise Tax shall be equal to the lesser of (x) the total amount of the Total Payments and (y) the amount of excess parachute payments within the meaning of Section 280G(b)(1) of the Code (after applying Section 7(i)(A) hereof); and

	(C)		the value of any non-cash benefits or any deferred payments or benefit shall be determined by a nationally-recognized accounting or consulting firm the selection of which was approved under Section 7(iv) in accordance with the principles of Sections 280G(d)(3) and (4) of the Code.

	(ii)		For purposes of determining the amount of the Gross-Up Payment, Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation in the calendar year in which the Gross-Up Payment is to be made and state and local income taxes at the highest marginal rate of taxation in the state and locality of Executive’s residence on the date of termination, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes. In the event that the Excise Tax is subsequently determined to be less than the amount taken into account hereunder at the time of termination of Executive’s employment, Executive shall repay to the Company within ten days after the time that the amount of such reduction in Excise Tax is finally determined the portion of the Gross-Up Payment attributable to such reduction (plus the portion of the Gross-Up Payment attributable to the Excise Tax and federal and state and local income tax imposed on the Gross-Up Payment being repaid by Executive if such repayment results in a reduction in Excise Tax and/or federal and state and local income tax deduction) plus interest on the amount of such repayment at the rate provided in Section 1274(b)(2)(B) of the Code. In the event that the Excise Tax is determined to exceed the amount taken into account hereunder at the time of the termination of Executive’s employment (including by reason of any payment the existence or amount of which cannot be determined at the time of the Gross-Up Payment), the Company shall make an additional gross-up payment in respect of such excess within ten days after the time that the amount of such excess is finally determined.

	(iii)		The payments provided for in this Section 7 shall be made not later than the thirtieth day following the date of Executive’s termination of employment; provided, however, that if the amount of such payments cannot be finally determined on or before such day, the Company shall pay to Executive on such day an estimate, as determined in good faith by the Company, of the minimum amount of such payments and shall pay the remainder of such payments (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code) as soon as the amount thereof can be determined but in no event later than the sixtieth day after the date of Executive’s termination of employment. In the event that the amount of the estimated payments exceeds the amount subsequently determined to have been due, such excess shall constitute a loan by the Company to Executive, payable on the fifteenth day after the demand by the Company (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code).

	(iv)		All determinations under this Section 7 shall be made at the expense of the Company by a nationally recognized public accounting or consulting firm selected by the Company and subject to the approval of Executive, which approval shall not be unreasonably withheld. Such determination shall be binding upon Executive and the Company.

8. Discoveries and Works; Confidentiality; Non-Competition and Non-Disclosure; Executive Cooperation; Non-Disparagement.

8.1 Discoveries and Works. The Executive understands and agrees that any and all Confidential Information (as hereinafter defined) of the Company which he has access to, uses or creates during his employment with the Company is and shall at all times remain the sole and exclusive property of the Company, and the Executive further agrees to assign to the Company any right, title or interest he may have in such Confidential Information to the Company. The Executive also agrees that, if he is asked by the Company (at its expense), he will do all things and sign all necessary documents reasonably necessary in the opinion of the Company to eliminate any ambiguity as to the right of the Company in such Confidential Information including but not limited to providing his full cooperation to the Company in the event of any litigation to protect, establish or obtain such rights of the Company.

The Executive understands that this Section 8.1 does not waive or transfer his rights to any invention for which no equipment, supplies, facility or trade secret or Confidential Information of the Company was used and which was developed entirely on his own time, unless the invention relates to the business of the Company, or to the Company’s actual demonstratively anticipated research or development, or the invention results from any work that he performed for the Company during the term of his employment relationship with the Company.

The Executive hereby assigns and transfers to the Company, its successors, legal representatives and assigns, his entire right, title, and interest in and to any and all present and future works of authorship, inventions, know-how, confidential information, proprietary information, or trade secrets resulting from work done by him on behalf of the Company (collectively, the “Intellectual Property”). The Executive agrees to waive all moral rights relating to the Intellectual Property developed or produced, including without limitation any and all rights of identification of authorship, any and all rights of approval, restriction or limitation on use or subsequent modifications and any and all rights to prevent any changes prejudicial to his honor or reputation. The Executive further agrees to provide all assistance reasonably requested by the Company in the establishment, preservation and enforcement of its rights in the Intellectual Property, such assistance to be provided at the Company’s expense, but without any additional compensation to the Executive.

8.2 Confidential Information. The Executive acknowledges that, during the course of his employment with the Company, the Executive may receive special training and/or may be given access to or may become acquainted with Confidential Information (as hereinafter defined) of the Company. As used in this Section 8.2, “Confidential Information” of the Company means all trade practices, business plans, price lists, supplier lists, customer lists, marketing plans, financial information, software and all other compilations of information which relate to the business of the Company, or to any of its subsidiaries, and which have not been disclosed by the Company to the public, or which are not otherwise generally available to the public.

The Executive acknowledges that the Confidential Information of the Company, as such may exist from time to time, are valuable, confidential, special and unique assets of the Company and its subsidiaries, expensive to produce and maintain and essential for the profitable operation of their respective businesses. The Executive agrees that, during the course of his employment with the Company, or at any time thereafter, he shall not, directly or indirectly, communicate, disclose or divulge to any Person (as such term is hereinafter defined), or use for his benefit or the benefit of any Person, in any manner, any Confidential Information of the Company or its subsidiaries acquired during his employment with the Company or any other confidential information concerning the conduct and details of the businesses of the Company and its subsidiaries, except as required in the course of his employment with the Company or as otherwise may be required by law. For purposes if this Agreement, “Person” shall mean any individual, partnership, corporation, trust, unincorporated association, joint venture, limited liability company or other entity or any government, governmental agency or political subdivision.

All documents relating to the businesses of the Company and its affiliates including, without limitation, Confidential Information of the Company, whether prepared by the Executive or otherwise coming into the Executive’s possession, are the exclusive property of the Company and such respective subsidiaries, and must not be removed from the premises of the Company, except as required in the course of the Executive’s employment with the Company. The Executive shall return all such documents (including any copies thereof) to the Company when the Executive ceases to be employed by the Company or upon the earlier request of the Company or the Board.

8.3 Noncompetition. During the Term of this Agreement (including any extensions thereof) and for a period of one (1) year following the termination of the Executive’s employment under this Agreement for any reason, which period shall be extended to two (2) years if such termination occurs in anticipation of a Change in Control (as defined in Section 6.2) or on or within two (2) years after a Change in Control, the Executive shall not, except with the Company’s express prior written consent, directly or indirectly, in any capacity, for the benefit of any entity or person (including the Executive):

(i)

Become employed by, own, operate, manage, direct, invest in (except through a mutual fund), or otherwise, directly or indirectly, engage in, or be employed by, any entity or person which competes with the Business (as hereinafter defined) within the Territory. For purposes of this Agreement, “Business” shall mean minimally invasive knee replacement surgery in combination with surgical navigation and robotics. For purposes of this Agreement, “Territory” shall mean the United States of America.

	(ii)		Divert or take away any customer or client of the Company, or any of its subsidiaries, or solicit, service, or promote a competing service that competes with the Business to any customer, client or employee of the Company, its subsidiaries or any of its respective businesses.

	(iii)		Solicit or hire any employee of the Company, or any of its subsidiaries.

8.4 Cooperation With Regard to Litigation. Executive agrees to cooperate with the Company, during the Term and thereafter (including following Executive’s termination of employment for any reason), by making himself available to testify on behalf of the Company or any subsidiary or affiliate of the Company, in any action, suit, or proceeding, whether civil, criminal, administrative, or investigative, and to assist the Company, or any subsidiary or affiliate of the Company, in any such action, suit, or proceeding, by providing information and meeting and consulting with the Board or its representatives or counsel, or representatives or counsel to the Company, or any subsidiary or affiliate of the Company, as may be reasonably requested and after taking into account Executive’s post-termination responsibilities and obligations. The Company agrees to reimburse Executive, on an after-tax basis, for all reasonable expenses actually incurred in connection with his provision of testimony or assistance and if such cooperation is provided more than one (1) year after Executive’s termination of employment, which period shall be extended to two (2) years in the event Executive has been paid severance pursuant to Section 5.2(ii) equal to two (2) times Executive’s Base Salary and average Annual Cash Incentive, Executive shall be paid a reasonable per diem fee.

8.5 Non-Disparagement. Executive shall not, at any time during the Term and thereafter make statements or representations, or otherwise communicate, directly or indirectly, in writing, orally, or otherwise, or take any action which may, directly or indirectly, disparage or be damaging to the Company, its subsidiaries or affiliates or their respective officers, directors, employees, advisors, businesses or reputations, nor shall members of the Board of Directors or Executive’s successor in office, or other executive officers of the Company, make any such statements or representations regarding Executive. Notwithstanding the foregoing, nothing in this Agreement shall preclude Executive or his successor or members of the Board of Directors or other executive officers of the Company from making truthful statements that are required by applicable law, regulation or legal process.

8.6 Release of Employment Claims. Executive agrees, as a condition to receipt of any termination payments and benefits provided for in Sections 4 and 5 herein (other than Compensation Accrued at Termination) (the “Termination Benefits”), that he will execute a general release in substantially the form attached hereto as Exhibit A.

8.7 Forfeiture of Outstanding Options and Other Equity Awards. The provisions of Sections 4 and 5 notwithstanding, if Executive fails to comply with the restrictive covenants under Section 8.1 — 8.3, all options to purchase Common Stock and other equity awards granted by the Company at and after the Effective Date and then held by Executive or a transferee of Executive shall be immediately forfeited and thereupon such options and equity awards shall be cancelled. Notwithstanding the foregoing, Executive shall not forfeit any option or equity award unless and until there shall have been delivered to him, within six months after the Board (i) had knowledge of conduct or an event allegedly constituting grounds for such forfeiture and (ii) had reason to believe that such conduct or event could be grounds for such forfeiture, a copy of a resolution duly adopted by a majority affirmative vote of the membership of the Board (excluding Executive) at a meeting of the Board called and held for such purpose (after giving Executive reasonable notice specifying the nature of the grounds for such forfeiture and not less than 30 days to correct the acts or omissions complained of, if correctable, and affording Executive the opportunity, together with his counsel, to be heard before the Board) finding that, in the good faith opinion of the Board, Executive has engaged in conduct set forth in this Section 8.7 which constitutes grounds for forfeiture of Executive’s options and equity awards; provided, however, that if any option is exercised or equity award is settled after delivery of such notice and the Board subsequently makes the determination described in this sentence, Executive shall be required to pay to the Company an amount equal to the difference between the aggregate value of the shares acquired upon such exercise of the option at the date of the Board determination and the aggregate exercise price paid by Executive and an amount equal to the fair market value of the shares delivered in settlement of the equity award at the date of such determination (net of any cash payment for the shares by Executive). Any such forfeiture shall apply to such options notwithstanding any term or provision of any option agreement. In addition, options and equity awards granted to Executive on or after the Effective Date, and gains resulting from the exercise of such options and settlement of such equity awards, shall be subject to forfeiture in accordance with the Company’s standard policies relating to such forfeitures and clawbacks, as such policies are in effect at the time of grant of such options or equity awards.

8.8 Survival. The provisions of this Section 8 shall survive the termination of the Term and any termination or expiration of this Agreement.

8.9 Remedies. Executive agrees that any breach of the terms of this Section 8 would result in irreparable injury and damage to the Company for which the Company would have no adequate remedy at law; Executive therefore also agrees that in the event of said breach or any threat of breach and notwithstanding Section 9 the Company shall be entitled to an immediate injunction and restraining order from a court of competent jurisdiction to prevent such breach and/or threatened breach and/or continued breach by Executive and/or any and all persons and/or entities acting for and/or with Executive, without having to prove damages. The availability of injunctive relief shall be in addition to any other remedies to which the Company may be entitled at law or in equity, but remedies other than injunctive relief may only be pursued in an

arbitration brought in accordance with Section 8. The terms of this paragraph shall not prevent the Company from pursuing in an arbitration any other available remedies for any breach or threatened breach of this Section 8, including but not limited to the recovery of damages from Executive. Executive hereby further agrees that, if it is ever determined, in an arbitration brought in accordance with Section 9, that willful actions by Executive have constituted wrongdoing that contributed to any material misstatement or omission from any report or statement filed by the Company with the U.S. Securities and Exchange Commission or material fraud against the Company, then the Company, or its successor, as appropriate, may recover all of any award or payment made to Executive, less the amount of any net tax owed by Executive with respect to such award or payment over the tax benefit to Executive from the repayment or return of the award or payment, pursuant to Sections 5.3 or 5.4, and Executive agrees to repay and return such awards and amounts to the Company within 30 calendar days of receiving notice from the Company that the Board has made the determination referenced above and accordingly the Company is demanding repayment pursuant to this Section 8.9. The Company or its successor may, in its sole discretion, affect any such recovery by (i) obtaining repayment directly from Executive; (ii) setting off the amount owed to it against any amount or award that would otherwise be payable by the Company to Executive; or (iii) any combination of (i) and (ii) above.

9. Governing Law; Disputes; Arbitration.

9.1 Governing Law. This Agreement is governed by and is to be construed, administered, and enforced in accordance with the laws of the Florida, without regard to conflicts of law principles. If under the governing law, any portion of this Agreement is at any time deemed to be in conflict with any applicable statute, rule, regulation, ordinance, or other principle of law, such portion shall be deemed to be modified or altered to the extent necessary to conform thereto or, if that is not possible, to be omitted from this Agreement. The invalidity of any such portion shall not affect the force, effect, and validity of the remaining portion hereof. If any court determines that any provision of Section 9 is unenforceable because of the duration or geographic scope of such provision, it is the parties’ intent that such court shall have the power to modify the duration or geographic scope of such provision, as the case may be, to the extent necessary to render the provision enforceable and, in its modified form, such provision shall be enforced.

9.2 Arbitration.

Judgment may be entered on the arbitrators’ award in any court having jurisdiction. For purposes of entering any judgment upon an award rendered by the arbitrators, the Company and Executive hereby consent to the jurisdiction of any or all of the following courts: (i) the United States District Court for the Southern District of Florida, (ii) any of the courts of the State of Florida, or (iii) any other court having jurisdiction. The Company and Executive further agree

that any service of process or notice requirements in any such proceeding shall be satisfied if the rules of such court relating thereto have been substantially satisfied. The Company and Executive hereby waive, to the fullest extent permitted by applicable law, any objection which it may now or hereafter have to such jurisdiction and any defense of inconvenient forum. The Company and Executive hereby agree that a judgment upon an award rendered by the arbitrators may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each party shall bear its or his costs and expenses arising in connection with any arbitration proceeding pursuant to this Section 9. Notwithstanding any provision in this Section 9, Executive shall be paid compensation due and owing under this Agreement during the pendency of any dispute or controversy arising under or in connection with this Agreement.

9.3 Interest on Unpaid Amounts. Any amount which has become payable pursuant to the terms of this Agreement or any decision by arbitrators or judgment by a court of law pursuant to this Section 9 but which has not been timely paid shall bear interest at the prime rate in effect at the time such amount first becomes payable, as quoted by the Company’s principal bank.

9.4 LIMITATION ON LIABILITIES. IF EITHER EXECUTIVE OR THE COMPANY IS AWARDED ANY DAMAGES AS COMPENSATION FOR ANY BREACH OR ACTION RELATED TO THIS AGREEMENT, A BREACH OF ANY COVENANT CONTAINED IN THIS AGREEMENT (WHETHER EXPRESS OR IMPLIED BY EITHER LAW OR FACT), OR ANY OTHER CAUSE OF ACTION BASED IN WHOLE OR IN PART ON ANY BREACH OF ANY PROVISION OF THIS AGREEMENT, SUCH DAMAGES SHALL BE LIMITED TO CONTRACTUAL DAMAGES PLUS INTEREST ON ANY DELAYED PAYMENT AT THE MAXIMUM RATE PER ANNUM ALLOWABLE BY APPLICABLE LAW FROM AND AFTER THE DATE(S) THAT SUCH PAYMENTS WERE DUE AND SHALL EXCLUDE CONSEQUENTIAL DAMAGES AND PUNITIVE DAMAGES EVEN IF THE RULES REFERRED TO IN SECTION 9.2 WOULD PROVIDE OTHERWISE.

9.5 WAIVER OF JURY TRIAL. TO THE EXTENT APPLICABLE, EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL FOR ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT. This provision is subject to Section 9.2, requiring arbitration of disputes hereunder.

10. Miscellaneous.

10.1 Integration. This Agreement cancels and supersedes any and all prior agreements and understandings between the parties hereto with respect to the employment of Executive by the Company, any parent or predecessor company, and the Company’s subsidiaries during the Term, but excluding existing contracts relating to compensation under executive compensation

and employee benefit plans of the Company and its subsidiaries. This Agreement constitutes the entire agreement among the parties with respect to the matters herein provided, and no modification or waiver of any provision hereof shall be effective unless in writing and signed by the parties hereto. Executive shall not be entitled to any payment or benefit under this Agreement which duplicates a payment or benefit received or receivable by Executive under such prior agreements and understandings or under any benefit or compensation plan of the Company.

10.2 Successors; Transferability. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise, and whether or not the corporate existence of the Company continues) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise and, in the case of an acquisition of the Company in which the corporate existence of the Company continues, the ultimate parent company following such acquisition. Subject to the foregoing, the Company may transfer and assign this Agreement and the Company’s rights and obligations hereunder to another entity that is substantially comparable to the Company in its financial strength and ability to perform the Company’s obligations under this Agreement. Neither this Agreement nor the rights or obligations hereunder of the parties hereto shall be transferable or assignable by Executive, except in accordance with the laws of descent and distribution or as specified in Section 10.3.

10.3 Beneficiaries. Executive shall be entitled to designate (and change, to the extent permitted under applicable law) a beneficiary or beneficiaries to receive any compensation or benefits provided hereunder following Executive’s death.

10.7 No General Waivers. The failure of any party at any time to require performance by any other party of any provision hereof or to resort to any remedy provided herein or at law or in equity shall in no way affect the right of such party to require such performance or to resort to such remedy at any time thereafter, nor shall the waiver by any party of a breach of any of the provisions hereof be deemed to be a waiver of any subsequent breach of such provisions. No such waiver shall be effective unless in writing and signed by the party against whom such waiver is sought to be enforced.

10.8 No Obligation To Mitigate. Executive shall not be required to seek other employment or otherwise to mitigate Executive’s damages upon any termination of employment; provided, however, that, to the extent Executive receives from a subsequent employer health or other insurance benefits that are substantially similar to the benefits referred to in Section 3.3 hereof, any such benefits to be provided by the Company to Executive following the Term shall be correspondingly reduced.

10.9 Offsets; Withholding. The amounts required to be paid by the Company to Executive pursuant to this Agreement shall not be subject to offset other than with respect to any amounts that are owed to the Company by Executive due to his receipt of funds as a result of his fraudulent activity. The foregoing and other provisions of this Agreement notwithstanding, all payments to be made to Executive under this Agreement, including under Sections 4 and 5, or otherwise by the Company, will be subject to withholding to satisfy required withholding taxes and other required deductions.

10.12 Due Authority and Execution. The execution, delivery and performance of this Agreement have been duly authorized by the Company and this Agreement represents the valid, legal and binding obligation of the Company, enforceable against the Company according to its terms.

10.13 Representations of Executive. Executive represents and warrants to the Company that he has the legal right to enter into this Agreement and to perform all of the obligations on his part to be performed hereunder in accordance with its terms and that he is not a party to any agreement or understanding, written or oral, which prevents him from entering into this Agreement or performing all of his obligations hereunder. In the event of a breach of such representation or warranty on Executive’s part or if there is any other legal impediment which prevents him from entering into this Agreement or performing all of his obligations hereunder, the Company shall have the right to terminate this Agreement forthwith in accordance with the same notice and hearing procedures specified above in respect of a termination by the Company for Cause pursuant to Section 5.1 and shall have no further obligations to Executive hereunder. Notwithstanding a termination by the Company under this Section 10.13, Executive’s obligations under Section 9 shall survive such termination.

11. D&O Insurance and Indemnification.

The Company will maintain directors’ and officers’ liability insurance during the Term and for a period of six years thereafter, covering acts and omissions of Executive during the Term, on terms substantially no less favorable than those in effect on the Effective Date. To the fullest extent permitted under applicable law, the Company shall indemnify, defend and hold the Executive harmless from and against any and all causes of action, claims, demands, liabilities,

damages, costs and expenses of any nature whatsoever (collectively, “Damages”) directly or indirectly arising out of or relating to the Executive discharging the Executive’s duties hereunder on behalf of the Company and/or its respective subsidiaries and affiliates, so long as the Executive acted in good faith within the course and scope of the Executive’s duties with respect to the matter giving rise to the claim or Damages for which the Executive seeks indemnification. The Company also shall advance expenses for which indemnification may be ultimately claimed as such expenses are incurred to the fullest extent permitted under applicable law, subject to any requirement that Executive provide an undertaking to repay such advances if it is ultimately determined that Executive is not entitled to indemnification; provided, however, that any determination required to be made with respect to whether Executive’s conduct complies with the standards required to be met as a condition of indemnification or advancement of expenses under applicable law and the Company’s governing documents or other agreement shall be made by independent counsel mutually acceptable to Executive and the Company (except to the extent otherwise required by law). This Section 11 shall survive the termination of the Term and any termination of the Agreement until such time as no indemnifiable liability can be lawfully asserted against Executive.

12. Certain Definitions. For purposes of this Agreement:
