Whereas, the Company considers the establishment and maintenance of a sound and vital management to be essential to protecting and enhancing the best interests of the Company and its stockholders;

Whereas, as a condition to the Company’s execution and delivery of this Agreement, the Parties are entering into a Non-Disclosure, Intellectual Property, Non-Competition and Non-Solicitation Agreement dated as of the date of this Agreement (the “Restrictive Covenants Agreement”);

Whereas, the Company recognizes that, as is the case with many publicly-held corporations, the possibility of a change in control of the Company exists and that such possibility, and the uncertainty and questions that it may raise among key personnel, may result in the departure or distraction of key personnel to the detriment of the Company and its stockholders, and

Whereas, the Compensation Committee (the “Compensation Committee”) of the Board of Directors of the Company (the “Board”) has determined that it is in the best interests of the Company that appropriate steps should be taken to reinforce and encourage the continued employment and dedication of the Company’s key personnel without distraction, including distraction from the possibility of a change in control of the Company and related events and circumstances.

Now, Therefore, as an inducement for and in consideration of the Executive remaining in its employ and for other good and valuable consideration, the Parties agree that the Executive shall receive the severance benefits set forth below in the event the Executive’s employment with the Company is terminated.

(a) Severance Payment.

(i) Amount. The Company shall pay the Executive an amount (the “Severance Payment”) equal to (i) 1.0 multiplied by the Base Salary with respect to the calendar year in which the Termination Date occurs and (ii) if the Compensation Committee has previously established a target Annual Bonus for the Executive with respect to the calendar year in which the Termination Date occurs, a pro rata target bonus (the “Pro-Rata Target Bonus”) determined by multiplying such target Annual Bonus of the Executive for such calendar year by a fraction, the numerator of which is the number of days in the calendar year in which the Termination Date occurs through the Termination Date and the denominator of which is three hundred sixty-five. The Pro-Rata Target Bonus shall be paid only in the event any performance goals established with respect to such target Annual Bonus have been satisfied. Payment of the Pro-Rata Target Bonus shall be delayed until following the date the Compensation Committee determines that such performance goals have been satisfied, in accordance with the rules applicable to the target Annual Bonus under the applicable bonus program established by the Compensation Committee (the “Determination Date”).

4

(ii) Payment. The Severance Payment is payable in a lump sum within two weeks following the Termination Date. Notwithstanding the foregoing, payments of the Pro-Rata Target Bonus portion of the Severance Payment shall be paid within thirty days following the Determination Date, except that if payment of one or more installments of the Pro-Rata Target Bonus portion of the Severance Payment must be delayed until following the Determination Date, the initial installment shall consist of a lump sum equal to the total of all such installments delayed or due as of such payment date, without adjustment for interest.

(b) Health Care Coverage Payments. Provided the Executive is covered by the Company’s health care plans immediately prior to the Termination Date, the Company shall pay to the Executive on a monthly basis, during the twelve-month period commencing on the Termination Date (or such shorter period ending as of the initial date the Executive is eligible for coverage under the health care plans of a subsequent employer), a taxable cash payment equal to the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA) premium for the highest level of coverage available under the Company’s group health plans, but reduced by the monthly amount that the Executive would pay for such coverage if the Executive was an active employee.

(c) Outstanding Equity Awards. The vesting of each and every outstanding equity award agreement executed by the Parties shall, to the extent such vesting is based upon the passage of time (rather than any performance metric) shall accelerate in full.

All other benefits, if any, due the Executive following termination pursuant to this Section 3.2 shall be determined in accordance with the plans, policies and practices of the Company, provided the Executive shall not be entitled to participate in any other severance plan, policy or program of the Company. The Severance Benefits are payments and benefits to which the Executive is not otherwise entitled, are given in consideration for the Release (as described in Sections 3.6 and 3. 7), and are in lieu of any severance plan, policy or program of the Company or any of its subsidiaries that may now or hereafter exist. The payments and benefits to be provided pursuant to this Section 3.2 shall constitute liquidated damages and shall be deemed to satisfy and be in full and final settlement of all obligations of the Company to the Executive under this Agreement. The Executive acknowledges and agrees that such amounts are fair and reasonable, and are the Executive’s sole and exclusive remedy, in lieu of all other remedies at law or in equity, with respect to the termination of the Executive’s employment.

In the event of the termination of the Executive’s employment by the Company for Cause or by the Executive without Good Reason or the expiration of the Term upon notice of nonrenewal delivered by the Executive in accordance with Section 2, the Executive shall have no further rights to any compensation (including any Annual Bonus) or any other benefits under this Agreement other than the Base Obligations. All other benefits, if any, due the Executive following the Executive’s termination of employment pursuant to this Section 3.4 shall be determined in accordance with the plans, policies and practices of the Company, provided that the Executive shall not be entitled to participate in any severance plan, policy, or program of the Company.

7

5.3 Entire Agreement; Amendments. This Agreement, together with the Restrictive Covenants Agreement, contains the entire understanding of the Parties with respect to the subject matter set forth in this Agreement, and shall supersede any and all previous contracts, arrangements or understandings between the Company and the Executive with respect to the subject matter set forth in this Agreement. This Agreement may not be altered, modified or amended except by written instrument signed by the Company and the Executive.

5.4 No Waiver. The failure of a Party to insist upon strict adherence to a term of this Agreement on any occasion shall not be considered a waiver of such Party’s rights or deprive such Party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement.

5.7 Withholding Taxes. The Company may withhold from any amounts payable under this Agreement such federal, state and local taxes as may be required to be withheld pursuant to any applicable law or regulation.

8

5.8 Section 409A. Notwithstanding any other provision of this Agreement, any payment, settlement or benefit triggered by termination of the Executive’s employment with the Company shall not be made until six months and one day following Termination Date if such delay is necessary to avoid the imposition of any tax, penalty or interest under Section 409A. Any installment payments that are delayed pursuant to this Section 5.8 shall be accumulated and paid in a lump sum on the day that is six months and one day following the Termination Date (or, if earlier, upon the Executive’s death) and the remaining installment payments shall begin on such date in accordance with the other provisions of this Agreement. For purposes of this Agreement, termination or severance of employment shall be read to mean a “separation from service” within the meaning of Section 409A where it is reasonably anticipated that no further services would be performed after that date or that the level of services the Executive would perform after that date (whether as an employee or independent contractor) would permanently decrease to no more than twenty percent of the average level of bona fide services performed over the immediately preceding thirty-six month period. Additionally, the amount of expenses eligible for reimbursement or in-kind benefits to be provided during one calendar year may not affect the expenses eligible for reimbursement or any in-kind benefits to be provided in any other calendar year and the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit. All reimbursements shall be made no later than the last day of the calendar year following the calendar year in which the Executive incurs the reimbursable expense. This Agreement is intended to comply with the requirements of Section 409A (including the exceptions thereto), to the extent applicable, and the Agreement shall be administered and interpreted in accordance with such intent. If any provision contained in the Agreement conflicts with the requirements of Section 409 A (or the exemptions intended to apply under the Agreement), the Agreement shall be deemed to be reformed to comply with the requirements of Section 409A (or the applicable exemptions thereto). The Company, after consulting with the Executive, may amend this Agreement or the terms of any award provided for in this Agreement in any manner that the Company considers necessary or advisable to ensure that cash compensation, equity awards or other benefits provided for in this Agreement are not subject to U.S. federal income tax, state or local income tax or any equivalent taxes in territories outside the United States prior to payment, exercise, vesting or settlement, as applicable, or any tax, interest or penalties pursuant to Section 409A. Any such amendments shall be made in a manner that preserves to the maximum extent possible the intended benefits to the Executive. This Section 5.8 does not create an obligation on the part of the Company to modify this Agreement and does not guarantee that the amounts or benefits owed under the Agreement shall not be subject to interest and penalties under Section 409A. For purposes of this Agreement, all rights to payments and benefits hereunder shall be treated as rights to receive a series of separate payments and benefits to the fullest extent allowed by Section 409A.

5.9 Clawback. The Executive agrees that compensation and benefits provided by the Company under this Agreement or otherwise shall be subject to recoupment or clawback by the Company under any applicable clawback or recoupment policy of the Company that is generally applicable to the Company’s executives, as may be adopted by the Board and in effect from time-to-time or as required by applicable law.
