Section 3. TERM AND TERMINATION PAYMENTS.

3.1 TERM. Subject to approval of this Agreement by the Board of Directors, the Term will commence on May 1, 2005, for two (2) consecutive twelve (12) month periods unless earlier terminated as a result of: (a) Company’s termination of Employee’s employment pursuant to Sections 3.2 or 3.4; or (b) Employee’s resignation of employment pursuant to Sections 3.3 or 3.4.

3.2 TERMINATION BY COMPANY. Company may terminate Employee’s employment with Cause effective immediately, or without Cause at any time by giving Employee written notice at least thirty (30) days prior to the effective date of termination; provided, that if such termination of employment is made by the Company without Cause prior to the expiration of the Term, then the Employee shall be entitled to the following benefits (the “Separation Benefits”):

(a) an amount equal to the annual base salary under Section 2.1 plus Employee’s target cash compensation under Section 2.2 for the remaining months of the Term following the effective date of termination of employment, payable in equal monthly installments over the twelve month period following the date of such termination (“Salary Continuation Period”);

(b) continuation of the benefits provided pursuant to Section 2.3, to the extent permitted by the applicable plans, for the remaining months of the Fiscal Year following the effective date of termination of employment; provided that if Employee elects to convert his health coverage under COBRA, the Company shall pay Employee’s COBRA premiums for the foregoing period; and

(c) all of the Employee’s outstanding incentive stock options, qualified and non-qualified, will automatically vest.

Employee’s eligibility for the foregoing Separation Benefits is conditioned on (a) Employee remaining available during the Salary Continuation Period to consult with the Company regarding matters for which he previously had responsibility as a Company executive; (b) Employee having first signed a release agreement in the form attached as Exhibit A, and (c) Employee’s agreement not to compete with the Company, or its successors or assigns, during the Salary Continuation Period.

If Employee’s employment is terminated within twelve months following a Change of Control either (a) by the Company (or any successor thereto) without Cause or (b) by Employee for Good Reason, Employee will be eligible to receive the Separation Benefits set forth in Section 3.2 above, subject to the conditions set forth therein.

3.5 TERMINATION BY DEATH OR DISABILITY. Employee’s employment shall terminate automatically upon Employee’s death or, to the extent permitted by law, Disability. In the event Employee’s employment is terminated by death or Disability, the Company shall pay all compensation to which Employee is entitled up through the date of such termination. Thereafter, all obligations of the Company shall cease. A termination by death or Disability shall not constitute a

3

termination without Cause for purposes of Sections 3.2 or 3.4 above, and in no event shall the Company be obligated to provide any benefits under Sections 3.2 or 3.4 if Employee’s employment is terminated by death or Disability. Nothing in this section shall affect Employee’s rights under any disability plan in which he is a participant.
