Notwithstanding the foregoing, nothing in this Section 3.2 shall preclude

The Annual Bonus, if any, shall be paid promptly after completion of the Company’s audited year-end financial statements for the fiscal year to which the Annual Bonus relates (but in any event no later than two and one-half months following the conclusion of the fiscal year to which the Annual Bonus relates) and at the same time as annual bonuses are paid to the other senior executive officers of the Company.

1.5.Business Expenses. Executive shall be entitled to reimbursement for all reasonable and necessary out-of-pocket business, entertainment and travel expenses incurred by Executive in connection with the performance of Executive’s duties hereunder in accordance with the Company’s expense reimbursement policies and procedures and the terms and conditions of this Agreement.

1.8.Termination of Employment in Connection With a Change in Control.

1.9.Release. Notwithstanding any provision herein to the contrary, the payment of any amount or provision of any benefit pursuant to Section 5.5, Section 5.6 or 5.8 (other than the Accrued Obligations) (collectively, the “Severance Benefits”) shall be conditioned upon Executive’s execution, delivery to the Company, and non-revocation of the

6

Release of Claims (and the expiration of any revocation period contained in such Release of Claims) within sixty (60) days following the date of Executive’s termination of employment hereunder. If Executive fails to execute the Release of Claims in such a timely manner so as to permit any revocation period to expire prior to the end of such sixty (60) day period, or timely revokes Executive’s acceptance of such release following its execution, Executive shall not be entitled to any of the Severance Benefits.

6.Section 280G. Notwithstanding anything to the contrary in this Agreement, this Section 6 shall apply in the event of (i) a “change in the ownership or effective control” of the Company or (ii) a “change in the ownership of a substantial portion of the assets” of the Company, each within the meaning of Section 280G of the Code (collectively, an “Excise Tax Event”). If an Excise Tax Event is consummated, and as a result any payments and benefits provided for in this Agreement, together with any other payments and benefits which Executive has the right to receive from the Company or any of its affiliates, would constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code), then the payments and benefits provided for in this Agreement shall be either (a) reduced (but not below zero) so that the present value of such total amounts and benefits received by Executive from the Company and its affiliates will be one dollar ($1.00) less than three times Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code) and so that no portion of such amounts and benefits received by Executive shall be subject to the excise tax imposed by Section 4999 of the Code, or any interest or penalties with respect to such excise tax (such excise tax, together with any such interest or penalties, are hereinafter collectively referred to as the “Excise Tax”), or (b) paid in full, whichever produces the better net after-tax position to Executive (taking into account any applicable Excise Tax and any other applicable taxes). The reduction of payments and benefits hereunder, if applicable, shall be made in the following order: (1) by reducing the amounts of any payments or benefits that would not constitute deferred compensation under Section 409A, to the extent necessary to decrease the payments subject to the Excise Tax, as agreed by the Company and Executive; (2) next, by reducing, payments or benefits to be paid in cash hereunder and that constitute deferred compensation under Section 409A in the order in which such payment or benefit would be paid or provided (beginning with such payment or benefit that would be made last in time and continuing, to the extent necessary, through to such payment or benefit that would be made first in time); and (3) finally, by reducing any non-cash or in-kind benefit to be provided hereunder and that constitute deferred compensation under Section 409A in a similar order to that described in clause (2). The determination as to whether any such reduction in the amount of the payments and benefits provided hereunder is necessary shall be made by the Company in good faith. If a reduced payment or benefit is made or provided and through error or otherwise that payment or benefit, when aggregated with other payments and benefits from the Company (or its affiliates) used in determining if a “parachute payment” exists, exceeds one dollar ($1.00) less than three times Executive’s base amount, then Executive shall immediately repay such excess to the Company upon notification that an overpayment has been made. Nothing in this Section 6 shall require the Company to be responsible for, or have any liability or obligation with respect to, Executive’s Excise Tax liabilities.

7

7.Cooperation. The parties agree that certain matters in which Executive will be involved during the Employment Term may necessitate Executive’s cooperation in the future. Accordingly, following the termination of Executive’s employment for any reason, to the extent reasonably requested by the Board, Executive shall cooperate with the Company in connection with matters arising out of Executive’s service to the Company; provided, that, the Company shall make reasonable efforts to minimize disruption of Executive’s other activities. The Company shall reimburse Executive for reasonable expenses incurred in connection with such cooperation and, to the extent that Executive is required to spend substantial time on such matters, the Company shall compensate Executive at an hourly rate based on Executive’s Base Salary on the Termination Date, unless such time is as a witness in a legal proceeding, in which case the Company will only pay costs and expenses as permitted by law.

8.Confidential Information. Executive recognizes that the nature of Executive’s services are such that Executive will have access to information that constitutes trade secrets, is of a confidential nature, is of great value to the Company Group or is the foundation on which the business of the Company is predicated (“Confidential Information”). Executive agrees, during Executive’s employment and thereafter, not to disclose to any person other than the Company Group’s employees or the Company Group’s legal counsel or other parties authorized by the Company Group to receive confidential information nor use for any purpose, other than the performance of this Agreement, any Confidential Information. Confidential Information includes data or material (regardless of form) which is: (a) a trade secret; (b) provided, disclosed or delivered to Executive by the Company, any officer, director, employee, agent, attorney, accountant, consultant or other person or entity employee by the Company in any capacity, any customer, borrower or business associate of the Company Group or any public authority having jurisdiction over the Company Group of any business activity conducted by the Company Group; or (c) produced, developed, obtained or prepared by or on behalf of Executive or the Company Group (whether or not such information was developed in the performance of this Agreement) with respect to the Company Group or any assets, business activities, officers, directors, employees, borrowers or customers of the foregoing. However, Confidential Information will not include any information, data or material which at the time of disclosure or use was generally available to the public other than by a breach of this Agreement, was available to the party to whom disclosed on a non-confidential basis by disclosure or access provided by the Company Group or a third party, or was otherwise developed or obtained independently by the person to whom disclosed without a breach of this Agreement. The foregoing notwithstanding, nothing in this Agreement prohibits Executive from reporting possible violations of federal law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, Congress, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal law or regulation. On request by the Company, the Company will be entitled to a copy of any Confidential Information in the possession of Executive. The provisions of this Section 8 will survive the termination, expiration or cancellation of Executive’s employment. Executive will deliver to the Company all originals and copies of the documents or materials containing Confidential Information. Executive further agrees that if Executive executes additional

8

Company policies or agreements to protect the Confidential Information, this Agreement shall be read in conjunction with any such policies or Agreements to provide the broadest and greatest protection to the Confidential Information.

Executive further acknowledges and agrees that the nature of Executive’s position gives Executive access to and knowledge of Confidential Information and places Executive in a position of trust and confidence with the Company Group. Executive further understands and acknowledges that the intellectual services he provides to the Company Group are unique, special, and extraordinary.

The Company and Executive agree, however, that if a court or agency of competent jurisdiction determines that any of the terms of this Section 9 are not enforceable because they are overbroad or for any other reason, the provisions of this Section 9 shall be reformed and modified to reflect restrictions that are determined to be reasonable by such court or agency of competent jurisdiction.

10.Non-Disparagement.

This Section 10 does not, in any way, restrict or impede Executive from exercising protected rights to the extent that such rights cannot be waived by agreement or from complying with any applicable law or regulation or a valid order of a court of competent jurisdiction or an authorized government agency, provided, that such compliance does not exceed that required by the law, regulation or order. Executive shall promptly provide written notice of any such order to the CEO.

19.Entire Agreement. Except as expressly set forth herein, this Agreement contains all of the understandings and representations between Executive and the Company pertaining to the subject matter hereof and supersedes all prior and contemporaneous understandings, agreements, representations and warranties, both written and oral, with respect to such subject matter, except that nothing herein shall be deemed to alter or amend that certain Indemnification Agreement between Executive and the Company or any of Executive’s obligations pursuant to any agreement or plan concerning confidential and proprietary information, intellectual property, or any other protective or restrictive covenants, each of which is intended to be preserved hereby and shall be in addition to, and not in lieu of, the similar restrictions and covenants set forth herein. The parties mutually agree that the Agreement can be specifically enforced in court and can be cited as evidence in legal proceedings alleging breach of the Agreement.

20.Modification and Waiver. No provision of this Agreement may be amended or modified unless such amendment or modification is agreed to in writing and signed by Executive and by an executive officer of the Company. No waiver by either of the parties of any breach by the other party hereto of any condition or provision of this Agreement to be performed by the other party hereto shall be deemed a waiver of any similar or dissimilar provision or condition at the same or any prior or subsequent time, nor shall the failure of or delay by either of the parties in exercising any right, power or privilege hereunder operate as a waiver thereof to preclude any other or further exercise thereof or the exercise of any other such right, power or privilege.

21.Severability. Should any provision of this Agreement be held by a court or arbitrator of competent jurisdiction to be enforceable only if modified, or if any portion of this Agreement shall be held as unenforceable and thus stricken, such holding shall not affect the validity of the remainder of this Agreement, the balance of which shall continue to be binding upon the parties with any such modification to become a part hereof and treated as though originally set forth in this Agreement. The parties further agree that any such court or arbitrator is expressly authorized to modify any such unenforceable provision of this Agreement in lieu of severing such unenforceable provision from this Agreement in its entirety, whether by rewriting the offending provision, deleting any or all of the offending provision, adding additional language to this Agreement or by making such other modifications as it deems warranted to carry out the intent and agreement of the parties as embodied herein to the maximum extent permitted by law. The parties expressly agree that this Agreement as so modified by the court or arbitrator shall be binding upon and enforceable against each of them. In any event, should one or more of the provisions of this Agreement be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions hereof, and if such provision or provisions are not modified as provided above, this Agreement shall be construed as if such invalid, illegal or unenforceable provisions had not been set forth herein.

22.Captions. Captions and headings of the sections and paragraphs of this Agreement are intended solely for convenience and no provision of this Agreement is to be construed by reference to the caption or heading of any Section or paragraph.

23.Counterparts. This Agreement may be executed in separate counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same instrument.

24.Additional Section 409A Provisions.

Notwithstanding any provision in this Agreement to the contrary:

1.1.Any payment that is deemed nonqualified deferred compensation (withing the meaning of Section 409A of the Code) and otherwise required to be made hereunder to Executive at any date as a result of the termination of Executive’s employment shall be delayed for such period of time as may be necessary to meet the requirements of Section 409A(a)(2)(B)(i) of the Code (the “Delay Period”). On the first business day following the expiration of the Delay Period, Executive shall be paid, in a single cash lump sum, an amount equal to the aggregate amount of all payments delayed pursuant to the preceding sentence, and any remaining payments not so delayed shall continue to be paid pursuant to the payment schedule set forth herein.

1.2.Each payment in a series of payments hereunder shall be deemed to be a separate payment for purposes of Section 409A of the Code.

1.3.Notwithstanding anything herein to the contrary, the payment (or commencement of a series of payments) hereunder of any nonqualified deferred compensation (within the meaning of Section 409A of the Code) upon a termination of employment shall be delayed until such time as Executive has also undergone a “separation from service” as defined in Treas. Reg. 1.409A-1(h), at which time such nonqualified deferred compensation (calculated as of the date of Executive’s termination of employment hereunder) shall be paid (or commence to be paid) to Executive on the schedule set forth in Section 5 as if Executive had undergone such termination of employment (under the same circumstances) on the date of Executive’s ultimate “separation from service.”

1.4.To the extent that any right to reimbursement of expenses or payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A of the Code), (i) any such expense reimbursement shall be made by the Company no later than the last day of the taxable year following the taxable year in which such expense was incurred by Executive, (ii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect.

15

1.5.To the extent any payment of nonqualified deferred compensation (within the meaning of Section 409A of the Code) is subject to the Executive’s execution and non-revocation of a Release of Claims and the period to consider and revoke such Release of Claims spans two taxable years, then the payment of such nonqualified deferred compensation shall be payable in the later of the two taxable years to the extent necessary to comply with Section 409A of the Code.

1.6.While the payments and benefits provided hereunder are intended to be structured in a manner to avoid the implication of any penalty taxes under Section 409A of the Code, in no event whatsoever shall any member of the Company Group be liable for any additional tax, interest, or penalties that may be imposed on Executive as a result of Section 409A of the Code for failing to comply with Section 409A of the Code (other than for withholding obligations or other obligations applicable to employers, if any, under Section 409A of the Code) provided that the Company Group act in reasonable good faith in connection with complying with Section 409A of the Code.

25.Successors and Assigns; No Third-Party Beneficiaries.

1.1.This Agreement shall inure to the benefit of the Company and its respective permitted successors and assigns. Neither this Agreement nor any of the rights, obligations, or interests arising hereunder may be assigned by the Company to any person other than to an acquiror of all or substantially all of the assets of the Company who assumes the agreement in writing.

1.2.Executive’s rights and obligations under this Agreement shall not be transferable by Executive by assignment or otherwise, without the prior written consent of the Company; provided, however, that if Executive shall die, all amounts then payable to Executive hereunder shall be paid in accordance with the terms of this Agreement to Executive’s devisee, legatee, or other designee, or if there be no such designee, to Executive’s estate.

1.3.Except as otherwise set forth in Section 5.3 or Section 25.2 hereof, nothing expressed or referred to in this Agreement will be construed to give any Person other than the Company, the other members of the Company Group, and Executive any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement.

26.Notification to Subsequent Employer. When Executive’s employment with the Company terminates, Executive agrees to notify any subsequent employer of the protective covenants sections contained in this Agreement. Executive will also deliver a copy of such notice to the Company before Executive commences employment with any subsequent employer. In addition, Executive authorizes the Company to provide a copy of the protective covenants sections of this Agreement to third parties, including but not limited to, Executive’s subsequent, anticipated or possible future employer.

16

27.Notice.

1.1.Place of Delivery. Every notice or other communication relating to this Agreement shall be in writing, and shall be mailed to or delivered to the party for whom or which it is intended at such address as may from time to time be designated by it in a notice mailed or delivered to the other party as herein provided; provided, that unless and until some other address be so designated, all notices and communications by Executive to the Company shall be mailed or delivered to the Company at its principal executive office, and all notices and communications by the Company to Executive may be given to Executive personally or may be mailed to Executive at Executive’s last known address, as reflected in the Company’s records.

28.Representations of Executive. Executive represents and warrants to the Company that:

1.1.Executive is entering into this Agreement voluntarily and that Executive’s employment hereunder and compliance with the terms and conditions hereof will not conflict with or result in the breach by Executive of any agreement to which Executive is a party or by which Executive may be bound;

1.2.Executive has not violated, and in connection with Executive’s employment with the Company will not violate, any non-solicitation, non-competition, or other similar covenant or agreement with any Person by which Executive is or may be bound; and

1.3.In connection with Executive’s employment with the Company, Executive will not use any confidential or proprietary information Executive may have obtained in connection with employment or service with any prior service recipient.

29.Survival. Upon the expiration or other termination of this Agreement, the respective rights and obligations of the parties hereto shall survive such expiration or other termination to the extent necessary to carry out the intentions of the parties under this Agreement.

30.Acknowledgment of Full Understanding. EXECUTIVE ACKNOWLEDGES AND AGREES THAT HE HAS FULLY READ, UNDERSTANDS AND VOLUNTARILY ENTERS INTO THIS AGREEMENT.
