This Agreement shall commence on the Effective Date and shall continue thereafter for a term of three (3) years and shall automatically renew for successive one (1) year terms unless earlier terminated in accordance with the terms hereof (such period from the date hereof until the termination date hereof, the “Term”).

3.    COMPENSATION.

In consideration for the Executive’s services hereunder, the Executive shall receive the following compensation (which compensation may be increased following the Business Combination based on an assessment of the Executive’s duties and performance):

A.    Base Salary. Beginning on first full payroll period to commence following the Effective Date and for the balance of the Term, the Corporation shall pay the Executive a base salary at a rate equal to $375,950 per annum (as adjusted from time to time in accordance with this Section 3.A, the “Base Salary”).

The terms of the New Option shall be governed in all respects by the terms of the notice of grant and award agreement to be entered into in connection with such grant and the terms and conditions of the New Plan, except as otherwise expressly set forth in this Agreement. Notwithstanding the foregoing, the Board may determine to grant such equity-based compensation award in whole or in part in a form other than a stock option, in which case the Share Number shall be equitably adjusted as determined in the Board’s reasonable discretion.

D.    Severance Benefits Upon Termination by the Corporation Without Cause or by the Executive for Good Reason Outside of the Change in Control Period.

F.    Conditions to Receipt of Severance Benefits. As a condition to receiving the payments and benefits set forth in Section 5.D and Section 5.E, (i) the Executive must execute and deliver to the Corporation a customary release of claims in a form reasonably acceptable to the Corporation (the “Release”) and the Release must have become effective and the revocation period provided therein must have expired without the Executive having revoked the Release within the 60-day period following the date of termination, and (ii) the Executive must not have revoked or breached the provisions of such Release or breached Section 9 or Section 12 of this Agreement, or the Proprietary Rights Agreement.  The Corporation shall provide the Release to the Executive within 21 days following the date of termination.

In the event the Corporation does not provide the Release to the Executive within 21 days following the date of termination, the Release shall no longer be required and the Executive shall nonetheless be entitled to the payments and benefits set forth in Section 5.D and Section 5.E.

8.    EXCLUSIVE EMPLOYMENT.

During Executive’s employment with the Corporation, the Executive will not do anything to compete with the present or contemplated business of the Corporation, suffer to exist any conflict of interest in respect of Executive’s relationship with the Corporation or plan or organize any competitive business activity (with the understanding that the ownership by the Executive of less than one percent (1%) of the outstanding shares of common stock of a publicly traded corporation shall not be deemed to violate the requirements of this sentence). The Executive is not a party to and will not enter into any agreement that conflicts with Executive’s duties or obligations to the Corporation; all corporate opportunities which are consistent with the business and purpose of the Corporation are to be the property of the Corporation and cannot be used or disclosed by Executive for any purpose other than performing Executive’s duties for the Corporation and Executive shall present to the Corporation any such opportunities of which Executive becomes aware; provided, however, that the provisions of this sentence are subject to the provisions of Article Eighth of the Amended and Restated Certificate of Incorporation of the Corporation. Executive shall at all times strictly comply with the Corporation’s conflicts of interest policy and any other policies adopted by the Board.

9.    RESTRICTIVE COVENANTS.

A.    In consideration of Executive’s employment and the provisions of this Employment Agreement, Executive agrees that during Executive’s employment with the Corporation, and for a period of nine (9) months following the termination of Executive’s employment with the Corporation for any reason, Executive will not solicit on behalf of himself or any organization other than the Corporation any person or entity who is then or within the last twelve (12) months was a customer or vendor of the

Corporation or render services directly or indirectly anywhere within the United States of America for himself or on behalf of any third-party to any organization that is a competitor of the Corporation as of the date of such termination.

B.    Executive agrees that for nine (9) months following the termination of Executive’s employment for any reason, Executive will not hire, solicit, recruit, encourage to leave or entice away, or endeavor to hire, solicit, recruit, encourage to leave or entice away from the Corporation any employee or exclusive consultant of the Corporation. The Corporation agrees that this Section 9.B shall not be breached if following termination of Executive’s employment by Corporation, Executive is associated with an organization that places general solicitations for employment and an employee or exclusive consultant of the Corporation is hired by such organization as a result of such general solicitation and without any specific solicitation of such employee or exclusive consultant.

C.    Executive agrees that the restrictions and agreements contained in this Agreement (including the Proprietary Rights Agreement) are reasonable and necessary to protect the legitimate interests of the Corporation and that any violation of the restrictive covenants contained herein will cause substantial and irreparable harm to the Corporation that would not be quantifiable and for which no adequate remedy would exist at law. Accordingly, Executive authorizes the issuance of injunctive relief against him without the requirement of posting bond, for any violation of e restrictive covenants contained herein. In addition, the parties agree that the prevailing party in any legal action to enforce this Agreement shall be entitled to recover its reasonable attorneys’ fees incurred in enforcing this Agreement from the non-prevailing party

10.    409A COMPLIANCE.

Notwithstanding any other provision of this Agreement, the Corporation and the Executive intend that any payments, benefits or other provisions applicable to this Agreement comply with the payout and other limitations and restrictions imposed under Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A” and the Internal Revenue Code of 1986, as amended, the “Code”), as clarified or modified by guidance from the U.S. Department of Treasury or the Internal Revenue Service, in each case if and to the extent Section 409A is otherwise applicable to this Agreement and such compliance is necessary to avoid the penalties otherwise imposed under Section 409A. In this connection, the Corporation and the Executive agree that the payments, benefits and other provisions applicable to this Agreement, and the terms of any deferral and other rights regarding this Agreement, shall be deemed modified if and to the extent necessary to comply with the payout and other limitations and restrictions imposed under Section 409A, as clarified or supplemented by guidance from the U.S. Department of Treasury or the Internal Revenue Service, in each case if and to the extent Section 409A is otherwise applicable to this Agreement and such compliance is necessary to avoid the penalties otherwise imposed under Section 409A. Any payments and benefits under this Agreement that qualify for the “short-term deferral” exemption or another exemption under Section 409A shall be paid under the applicable exemption. For purposes of the Section 409A, each payment of compensation under this Agreement shall be treated as a separate payment of compensation. Notwithstanding anything in this Agreement to the contrary, if any amounts or benefits payable under this Agreement in the event of Executive’s termination of employment constitute “nonqualified deferred compensation” within the meaning of Code Section 409A, payment of such amounts and benefits shall commence when the Executive incurs a “separation from service” within the meaning of Treasury Regulation 1.409A-1(h) (“Separation from Service”). Such payments or benefits shall be provided in accordance with the timing provisions of this Agreement by substituting the Agreement’s references to “termination of employment” or “termination” with Separation from Service. In addition, if at the time of Executive’s Separation from Service the Executive is a “specified employee” within the meaning of Code Section 409A(a)(2)(B)(i), any amount or benefits

that the constitutes “nonqualified deferred compensation” within the meaning of Code Section 409A that becomes payable to Executive on account of the Executive’s Separation from Service will not be paid until after the earlier of (i) first business day of the seventh month following Executive’s Separation from Service, or (ii) the date of the Executive’s death (the “409A Suspension Period”). Within 14 calendar days after the end of the 409A Suspension Period, the Executive shall be paid a cash lump sum payment equal to any payments and benefits that the Corporation would otherwise have been required to provide under this Agreement but for the imposition of the 409A Suspension Period delayed because of the preceding sentence. Thereafter, the Executive shall receive any remaining payments and benefits due under this Agreement in accordance with the terms of this Section (as if there had not been any Suspension Period beforehand). To the extent not otherwise specified in this Agreement, all (A) reimbursements and (B) in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A of the Code, including, where applicable, the requirement that (1) any reimbursement is for expenses incurred during the Executive’s lifetime (or during a shorter period of time specified in this Agreement); (2) the amount of expenses eligible for reimbursement, or in kind benefits provided, during a calendar year may not affect the expenses eligible for reimbursement, or in kind benefits to be provided, in any other calendar year; (3) the reimbursement of an eligible expense will be made no later than the last day of the calendar year following the year in which the expense is incurred; and (4) the right to reimbursement or in kind benefits is not subject to liquidation or exchange for another benefit.

11.    SECTION 280G.

In the event that the severance and other benefits provided for in this Agreement or otherwise payable to the Executive (i) constitute “parachute payments” within the meaning of Section 280G of the Code and (ii) but for this Section 11, would be subject to the excise tax imposed by Section 4999 of the Code, then, the Executive’s severance and other benefits under this Agreement shall be payable either (i) in full, or (ii) as to such lesser amount which would result in no portion of such severance and other benefits being subject to the excise tax under Section 4999 of the Code, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999 of the Code, results in the receipt by the Executive on an after-tax basis of the greatest amount of severance benefits under this Agreement, notwithstanding that all or some portion of such severance benefits may be taxable under Section 4999 of the Code. Any reduction shall be made in the following order: (i) reduction of cash payments, (ii) cancellation of accelerated vesting of equity awards, and (iii) reduction of other benefits payable to the Executive. Unless the Corporation and the Executive otherwise agree in writing, any determination required under this Section 11 shall be made in writing by the Corporation’s independent public accountants (the “Accountants”), whose determination shall be conclusive and binding upon the Executive and the Corporation for all purposes. For purposes of making the calculations required by this Section 11, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Corporation and the Executive shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section 11. The Corporation shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 11.

12.    INDEMNIFICATION.

The Corporation shall indemnify the Executive, to the maximum extent permitted by applicable law, and in the same or better manner and to the same or better extent with respect to each aspect of the indemnification as provided to any other executive of the Corporation (including without limitation any Directors and Officers insurance coverage), against all costs, charges and expenses incurred or sustained

by the Executive in connection with any action, suit or proceeding to which the Executive may be made a party, brought by any shareholder of the Corporation directly or derivatively or by any third party by reason of any act or omission of the Executive as an officer, director or employee of the Corporation or of any subsidiary or affiliate of the Corporation.

13.    NO DUTY TO MITIGATE.

In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any provisions of this Agreement.
