1.6 Severance and Termination.

1.6.1 Voluntary Termination, Termination for Cause, Termination for Death or Disability. In the case of a termination of Executive’s employment hereunder for Death or Disability in accordance with Section 1.5.1 above, or Executive’s Voluntary termination of employment hereunder in accordance with Section 1.5.2 above, or a termination of Executive’s employment hereunder for Cause in accordance with Section 1.5.3 above, or a termination of Executive’s employment hereunder Without Cause in accordance with Section 1.5.4 above that is not in connection with a Change in Control, (i) Executive shall not be entitled to receive payment of, and the Company shall have no obligation to pay, any severance or similar compensation attributable to such termination, other than Base Salary earned but unpaid, vested benefits under any employee benefit plan, and any unreimbursed expenses pursuant to Section 1.4.3 hereof incurred by Executive as of the Termination Date, and (ii) the Company’s other obligations under this Agreement shall immediately cease.

1.6.2 Termination Without Cause or Resignation for Good Reason – In Connection with a Change in Control. Subject to the provisions set forth in this Agreement, in the case of a termination of Executive’s employment hereunder Without Cause in accordance with Section 1.5.4 above or the resignation of Executive’s employment hereunder for Good Reason in accordance with Section 1.5.5 above, in each case, sixty days prior to or within twelve months after a Change in Control, the Company shall provide the following severance package (“CIC Severance Package”): (i) Company shall pay Executive an amount equivalent to six months of Executive’s then Base Salary plus fifty percent of Executive’s Bonus Base, subject to the tax withholding specified in Sections 1.4.1 and 1.4.2 above, payable as set forth herein (“CIC Severance Payment”); (ii) to the extent Executive participates in any medical, prescription drug, dental, vision and any other “group health plan” of the Company immediately prior to the Termination Date, the Company shall pay to Executive in a lump sum a fully taxable cash payment in an amount equal to six times the monthly premium cost to Executive of continued coverage for Executive (and for Executive’s spouse and dependents to the extent participating in such plans immediately prior to the Termination Date) that would be incurred for continuation coverage under such plans in accordance with Section 4980B of the Internal Revenue Code of 1986, as amended, and Part 6 of Title 1 of the Employee Retirement Income Security Act of 1986, as amended, less applicable tax withholding payable on the first payday following the 30th day after Executive’s termination date (Executive may, but is not obligated to, use such payment toward the cost of continuation coverage premiums); and (iii) one-hundred percent of any unvested shares subject to any equity grants issued to Executive by Company shall accelerate and vest and become exercisable in full. Company’s obligation to provide Executive with the CIC Severance Package is contingent upon Executive’s execution of a general release of claims satisfactory to the Company, with such release becoming effective on or before 30 days following Executive’s termination date. Payment of the CIC Severance Payment will commence on the first payday following the 30th day after Executive’s termination date and continue over a twelve month period in equal installments, with payments made on Company’s regular paydays. Such release will not affect Executive’s continuing obligations to the Company under the Proprietary Information and Inventions Agreement. The Company’s obligation to pay and Executive’s right to receive the CIC Severance Package set forth herein shall cease in the event of Executive’s material breach of any of his obligations under this Agreement or the Proprietary Information and Inventions Agreement. For the purposes of this Agreement, “Change in Control” shall mean (i) a merger or consolidation or the sale, or exchange by the stockholders of the Company of all or substantially all of the capital stock of the Company, where the stockholders of the Company immediately before such transaction do not obtain or retain, directly or indirectly, at least a majority of the beneficial interest in the voting stock or other voting equity of the surviving or acquiring corporation or other surviving or acquiring entity, in substantially the same proportion as before such transaction, or (ii) the sale or exchange of all or substantially all of the Company’s assets (other than a sale or transfer to a subsidiary of the Company as defined in Section

3

424(f) of the Internal Revenue Code of 1986, as amended) where the stockholders of the Company immediately before such sale or exchange do not obtain or retain, directly or indirectly, at least a majority of the beneficial interest in the voting stock or other voting equity of the corporation or other entity acquiring the Company’s assets, in substantially the same proportion as before such transaction.

1.7 Application of Section 409A.

1.7.1 All references in this Agreement, however phrased, to the termination of Executive shall mean, and be deemed to occur where there has been, a “separation from service” within the meaning of the Section 409A Regulations under the Internal Revenue Code with respect to payment of amounts that are deemed deferred compensation subject to the Section 409A Regulations. Furthermore, to the extent that Executive is a “specified employee” within the meaning of the Section 409A Regulations as of the date of Executive’s separation from service, no amount that constitutes a deferral of compensation which is payable on account of Executive’s separation from service shall be paid to Executive before the date (the “Delayed Payment Date”) which is first day of the seventh month after the date of Executive’s separation from service or, if earlier, the date of Executive’s death following such separation from service, and all such amounts that would, but for this sentence, become payable prior to the Delayed Payment Date will be accumulated and paid on the Delayed Payment Date.

1.7.2 Company intends that income provided to Executive pursuant to this Agreement will not be subject to taxation under Section 409A of the Internal Revenue Code. The provisions of this Agreement shall be interpreted and construed in favor of satisfying any applicable requirements of Section 409A of the Code. However, Company does not guarantee any particular tax effect for income provided to Executive pursuant to this Agreement. In any event, except for Company’s responsibility to withhold applicable income and employment taxes from compensation paid or provided to Executive, Company shall not be responsible for the payment of any applicable taxes on compensation paid or provided to Executive pursuant to this Agreement.

1.7.3 Notwithstanding anything herein to the contrary, the reimbursement of expenses or in-kind benefits provided pursuant to this Agreement shall be subject to the following conditions: (1) the expenses eligible for reimbursement or in-kind benefits in one taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits in any other taxable year; (2) the reimbursement of eligible expenses or in-kind benefits shall be made the earliest of (i) the date called for under Company’s applicable policies, (ii) the time provided by this Agreement, and (iii) the end of the year after the year in which such expense was incurred; and (3) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit.

1.7.4 For purposes of Section 409A of the Code, the right to a series of installment payments under this Agreement shall be treated as a right to a series of separate payments.

Executive is currently a party to the Proprietary Information and Inventions Agreement, a copy of which is attached hereto as Exhibit A and incorporated herein by this reference.

4.10 Severability. The Company and Executive intend all provisions of this Agreement to be enforced to the fullest extent permitted by law. Accordingly, if a court of competent jurisdiction determines that the scope and/or operation of any provision of this Agreement is too broad to be enforced as written, the Company and Executive intend that the court should reform such provision to such narrower scope and/or operation as it determines to be enforceable. If, however, any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future law, and not subject to reformation, then (i) such provision shall be fully severable, (ii) this Agreement shall be construed and enforced as if such provision was never a part of this Agreement, and (iii) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by illegal, invalid, or unenforceable provisions or by their severance.

Executive and Company further agree that Company shall have the right to forgo arbitration and seek injunctive relief from the courts if Executive breach the Proprietary Information and Inventions Agreement. The mutual promise by Company and Executive to arbitrate any and all disputes between them, rather than litigate them before the courts or other bodies, provides the consideration for this agreement to arbitrate.
