Subject to his executing and failing to revoke a general release of claims against the Company to the Company’s satisfaction within the later of 5 days after his date of termination or the expiration of the revocation period, Executive shall also receive (1) a lump sum payment equal to one million two hundred thousand dollars ($1,200,000) and (2) provided that Executive timely elects continued health coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), payment or reimbursement by the Company of Executive’s COBRA premiums until the earlier of (a) twelve (12) months or (b) the termination of Executive’s applicable COBRA continuation period.

4

purchase the Company’s stock shall remain exercisable, to the extent vested as of his date of termination, until the earlier of (a) twelve (12) months after the date of termination, or (b) the expiration of their original term.

4.3 Mitigation. Executive shall not be required to mitigate damages or the amount of any payment provided under this Agreement by seeking other employment or otherwise, nor shall the amount of any payment provided for under this Agreement be reduced by any compensation earned by Executive as a result of employment by another employer or by any retirement benefits received by Executive after the date of the Covered Termination, or otherwise.

4.4 Section 409A. Notwithstanding any provision to the contrary in this Agreement, if Executive is deemed by the Company at the time of his separation from service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code, 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(a)(2)(B)(i) of the Code, such portion of Executive’s benefits shall not be provided to Executive prior to the earlier of (a) the expiration of the six (6) month period measured from the date of the Executive’s “separation from service” with the Company (as such term is defined in the regulations issued under Section 409A of the Code) or (b) the date of Executive’s death. Upon the expiration of the applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this Section 4.4 shall be paid in a lump sum to the Executive, and any remaining payments due under the Agreement shall be paid as otherwise provided herein.

ARTICLE VI

CONFIDENTIAL INFORMATION, NON-COMPETITION AND NON-SOLICITATION,

NON-DISPARAGEMENT

6.1 Proprietary Information. Executive shall continue to abide by the terms and conditions of the Company’s standard Employee Proprietary Information and Inventions Agreement, the terms and conditions of which are incorporated herein by reference. Executive’s duties under the Proprietary Information Agreement shall survive termination of Executive’s employment with the Company and the termination of this Agreement.

6.2 Non-Competition. While employed by the Company, Executive shall not, directly in any manner or capacity (e.g., as an advisor, principal, agent, partner, officer, director, shareholder, employee, member of any association or otherwise) engage in, work for, consult, provide advice or assistance or otherwise participate in any activity which is competitive with the business of the Company in any geographic area in which the Company is now or shall then be doing business. Executive further agrees that while employed by the Company he will not assist or encourage any other person in carrying out any activity that would be prohibited by the provisions of this Section 6.2 if such activity were carried out by Executive and, in particular, Executive agrees that he will not induce any employee of the Company to carry out any such activity; provided, however, that the “beneficial ownership” by Executive, either individually or as a member of a “group,” as such terms are used in Rule 13d of the General Rules and Regulations under the Exchange Act, of not more than five percent (5%) of the voting stock of any publicly held corporation shall not be a violation of this Agreement.

6.3 Non-Solicitation and Confidential Information. While employed by the Company and for one (1) year thereafter Executive shall not, directly or indirectly, influence or attempt to influence customers or suppliers of the Company or any of its subsidiaries or affiliates, to divert their business to any competitor of the Company. Executive recognizes that he will possess confidential information about other employees of the Company relating to their education, experience, skills, abilities, compensation and benefits, and interpersonal relationships with customers of the Company. Executive recognizes that the information he will possess about these other employees is not generally known, is of substantial value to the Company in developing its business and in securing and retaining customers, and will be acquired by him because of his business position with the Company. Executive agrees that, while employed by the Company and for one (1) year thereafter, he will not, directly or indirectly, solicit or recruit any employee of the Company for the purpose of being employed by him or by any competitor of the Company on whose behalf he is acting as an agent, representative or employee and that he will not convey any such confidential information or trade secrets about other employees of the Company to any other person.

6.4 Non-Disparagement. Executive agrees to respect the reputation of and not disparage the Company. Company agrees to cause its officers and directors to respect the reputation of and not disparage Executive.

6.5 Remedies. Executive acknowledges that a remedy at law for any breach or threatened breach by Executive of the provisions of the Proprietary Information and Inventions Agreement or any of the covenants in this Article VII would be inadequate, and Executive therefore agrees that the Company shall be entitled to seek injunctive relief in case of any such breach or threatened breach.

6.6 Limitations. If it is determined by a court of competent jurisdiction in any state that any restriction in this Article VII is excessive in duration or scope or is unreasonable or unenforceable under the laws of that state, it is the intention of the parties that such restriction may be modified or amended by the court to render it enforceable to the maximum extent permitted by the law of that state.

ARTICLE VII

7.8 Arbitration.
