RECITALS

A. The Board of Directors of the Company (the “Board”) has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued dedication and objectivity of the Employee, notwithstanding the possibility, threat or occurrence of a termination of employment.

B. The Board believes that it is in the best interests of the Company and its shareholders to provide the Employee with an incentive to continue his or her employment with the Company.

C. The Board believes that it is imperative to provide the Employee with certain benefits upon termination of the Employee’s employment, which benefits are intended to provide the Employee with financial security and provide sufficient encouragement to the Employee to remain with the Company.

D. To accomplish the foregoing objectives, the Board of Directors has directed the Company, upon execution of this Agreement by the Employee, to agree to terms provided in this Agreement.

E. Certain capitalized terms used in the Agreement are defined in Section 3 below.

In consideration of the mutual covenants contained in this Agreement, and in consideration of the continuing employment of Employee by the Company, the parties agree as follows:

1. At-Will Employment. The Company and the Employee acknowledge that the Employee’s employment is and shall continue to be at-will, as defined under applicable law. If the Employee’s employment terminates for any reason, the Employee shall not be entitled to any benefits, other than as provided by this Agreement, or as may otherwise be available in accordance with the terms of the Company’s established employee plans and written policies at the time of termination. The terms of this Agreement shall terminate upon the earlier of (i) the date on which Employee ceases to be employed as an employee of the Company, other than as a result of a termination by the Company without Cause or an Involuntary Resignation or (ii) the date that all obligations of the parties hereunder have been satisfied. A termination of the terms of this Agreement pursuant to the preceding sentences shall be effective for all purposes, except that such termination shall not affect the provision of benefits on account of a termination of employment occurring prior to the termination of the terms of this Agreement.

2. Termination Benefits.

(i) Prior to a Change of Control. Subject to Section 4 below, if the Employee’s employment with the Company is terminated at any time prior to a Change of Control, then the Employee shall be entitled to receive benefits as follows:

(a) Voluntarily Resignation or Termination for Cause. If the Employee voluntarily resigns from the Company (other than as an Involuntary Resignation (as defined below) or if the Company terminates the Employee’s employment for Cause (as defined below)), then the Employee shall not be entitled to receive any acceleration of vesting or any other severance benefits. The Employee’s benefits will be terminated under the Company’s then existing benefit plans and policies in accordance with such plans and policies in effect on the date of termination or as otherwise determined by the Board of Directors of the Company.

(b) Involuntary Resignation or Termination without Cause. If the Employee resigns as a result of an Involuntary Resignation or if the Company terminates the Employee’s employment without Cause, then Employee shall be entitled to the following benefits subject to the execution of a mutually acceptable separation agreement including a general release of claims with respect to the Company or its successor and related parties:

(1) Acceleration of Vesting. The vesting of any stock option or restricted stock then held by Employee shall automatically be accelerated as though Employee maintained his employment or consulting relationship with the Company for a period of 6 months following the date of such Involuntary Resignation or termination. Apart from the foregoing, each such option shall be exercisable in accordance with the provisions of the option agreement and plan pursuant to which such option was granted.

(2) Severance. A cash payment in an amount equal six to (6) months of the sum of the Employee’s then current base salary and pro-rated portion of his target annual bonus, if any, subject to the execution of a mutually acceptable separation agreement including a general release of claims with respect to the Company or its successor and related parties;

(3) Benefits. The Employee shall be entitled to continue his health insurance benefits at the same level of coverage as was provided to such employee immediately prior to such termination (“Health Care Coverage”) by electing COBRA continuation coverage, provided the Company is subject to COBRA at the time of Employee’s termination of employment. Should the Employee elect COBRA, the Company shall pay 100% of Employee’s health care coverage premiums for 6 months (“Premiums”). If such Health Care Coverage included the Employee’s dependents immediately prior to such termination, the Company shall pay 100% of such dependent’s premiums. If the Employee (or a dependant of Employee) is eligible for further COBRA coverage (in excess of 6 months), Employee shall maintain such coverage at his sole expense. In the event the Company is not subject to COBRA at the time of Employee’s termination of employment, the Employee shall be entitled to reimbursement of his premium cost for individual health insurance coverage up to the amount the Company would have paid as Premiums under this paragraph had the Company been subject to

2

COBRA. The Company shall cease to pay the Premiums for the Employee and his dependents if Employee and his dependents become covered under another employer’s group health plan which provides Employee and his dependents with comparable benefits and levels of coverage and which does not contain any exclusion or limitation with respect to any pre-existing condition of the Employee or his dependents. The Company shall not cancel already existing life insurance policies or disability insurance policies, provided that the Employee continues such policies at the Employee’s expense, and further provided that the continuation of such policies is permitted by the policies and the insurers.

(ii) Upon or After a Change of Control. Subject to Section 4 below, if the Employee’s employment with the Company is terminated upon or at any time within 12 months after a Change of Control, then the Employee shall be entitled to receive benefits as follows:

(a) Voluntary Resignation or Termination for Cause. If the Employee voluntarily resigns from the Company (other than as an Involuntary Resignation (as defined below) or if the Company terminates the Employee’s employment for Cause (as defined below)), then the Employee shall not be entitled to receive any acceleration of vesting or any other severance benefits.

(b) Involuntary Resignation or Termination without Cause. If the Employee resigns as a result of an Involuntary Resignation or if the Company terminates the Employee’s employment without Cause, then Employee shall be entitled to the following benefits subject to the execution of a mutually acceptable separation agreement including a general release of claims with respect of claims with respect to the Company or its successor and related parties:

(1) Acceleration of Vesting. The vesting of any stock option or restricted stock then held by employee shall automatically be accelerated as though Employee maintained his employment or consulting relationship with the Company for a period of 12 months following the date of such Involuntary Resignation or termination.

(2) Severance. A cash payment in an amount equal to 12 months of the sum of the Employee’s then current base salary and target annual bonus, if any;

(3) Benefits. The Employee shall be entitled to continue his health insurance benefits at the same level of coverage as was provided to such employee immediately prior to such termination (“Health Care Coverage”) by electing COBRA continuation coverage, provided the Company is subject to COBRA at the time of Employee’s termination of employment. Should the Employee elect COBRA, the Company shall pay 100% of Employee’s health care coverage premiums for 12 months (“Premiums”). If such Health Care Coverage included the Employee’s dependents immediately prior to such termination, the Company shall pay 100% of such dependent’s premiums. If the Employee (or a dependant of Employee) is eligible for further COBRA coverage (in excess of 12 months), Employee shall

maintain such coverage at his sole expense. In the event the Company is not subject to COBRA at the time of Employee’s termination of employment, the Employee shall be entitled to reimbursement of his premium cost for individual health insurance coverage up to the amount the Company would have paid as Premiums under this paragraph had the Company been subject to COBRA. The Company shall cease to pay the Premiums for the Employee and his dependents if Employee and his dependents become covered under another employer’s group health plan which provides Employee and his dependents with comparable benefits and levels of coverage and which does not contain any exclusion or limitation with respect to any pre-existing condition of the Employee or his dependents.

The Company and the Employee shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make determination under this Section. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 4.

(b) The payment of severance benefits provided for in this Agreement shall be subject to all applicable income, employment and social tax rules and regulations.
