Employee further agrees that any such injunctive relief obtained by the Company shall be in addition to, and not in lieu of, monetary damages and any other remediesto which the Company may be entitled. Further, in the event of an alleged breach or violation by Employee of any of the provisions of Sections 4.3,4.4 or 4.5 hereof, the Non-Disclosure Period, the Noninterference Period and/or the Non-Competition Period, as the case may be, shall be tolled until such breach or violation has been cured.

Employee's Annual Base Compensation and accrued but unpaid vacation through the date thereof plus a pro rata portion of Employee's Potential Annual Target Bonus for the calendar year in which such death or Total Disability occurred (based on the number of days Employee was employed during the applicable calendar year), in accordance with the policy of the Company, and to continue to participate in the Company's health, insurance and disability plans and programs through the date of termination and thereafter only to the extent permitted under the terms of such plans and programs.

(c) Termination by Company Without Cause: If the Triggering Event was a Termination by the Company Without Cause, Employee shall be entitled to receive his Annual Base Compensation and accrued but unpaid vacation through the date thereof plus, in the reasonable discretion of the Company's Compensation Committee based upon whether it then appears the Potential Annual Target Bonus for the year would have been earned by Employee had he remained employed by the Company, a pro rata portion of Employee's Potential Annual Target Bonus for the calendar year in which such Triggering Event occurred (based on the number of days Employee was employed during the applicable calendar year), payable in accordance with the Company's normal payroll practices, and for the twelve (12) month period following the date of termination of Employee's employment with the Company (the "Severance Period"), an amount per month equal to one-twelfth (1/12^th) of Employee's Annual Base Compensation on the date of termination in installments consistent with the Company's normal payroll practices, commencing with the first regular payroll payment date following the termination of the Employment Period (collectively, the "Severance Benefits"); provided that Employee shall be entitled to receive such Severance Benefits during the Severance Period if (i) Employee has executed and delivered to the Company the General Release substantially in form and substance as set forth in Exhibit B to this Agreement; and (ii) Employee has not breached any of his covenants to the Company set forth in this Agreement. Notwithstanding the term of this Agreement or anything contained herein to the contrary, the duration of the Severance Period as well as the continuation of Employee's Annual Base Compensation during such Severance Period shall not exceed the amount set forth in this Section 5.2(c).

(d) Cessation of Entitlements and Company Right of Offset.

execute and deliver to the Company the Termination Certificate attached hereto as Exhibit A and by this reference made a part hereof.

6.2 Right of Company to Assign.
