SEVERANCE BENEFITS

2.1  Severance Benefits. The severance benefits provided under the Plan are as follows:

(a)  If a Covered Employee who is subject to an Involuntary Termination agrees to execute and does, in fact, execute a release as described in Section 2.2, he shall be entitled to a minimum Severance Amount of Base Pay. The foregoing notwithstanding on a case by case basis with respect to any individual Covered Employee or group of Covered Employees the Company may, in its sole discretion, increase the Severance Amount; and provided, further, that the Company, in its sole discretion, may with respect to any Covered Employee and on a case by case basis waive any condition or rule imposed under the Plan as a condition for eligibility for a Severance Amount benefit. If a Covered Employee who is subject to an Involuntary Termination does not execute a release as described in Section 2.2, he shall be entitled to Pay in Lieu of Notice, if any, as determined under Section 2.1(b).

(b)  The Company may, in its sole discretion and where it deems appropriate, pay an amount of Pay in Lieu of Notice to a Covered Employee when such Covered Employee has been terminated by the Company without advance notice if he is not otherwise eligible for benefits under this Plan or to any other employee whose employment has been terminated by the Company without advance notice.

(c)  Any Covered Employee who becomes eligible to receive a payment described in Paragraph (a) or (b) above shall be entitled to continue his and his family members' coverage under the Company's medical and dental benefit plans for a period of time and in a manner as the Company may determine in its sole discretion; provided that such coverage may be continued only at the level and for the person or persons covered as in effect as of the date of the Covered Employee's Involuntary Termination. The Company may, in its sole discretion and where it deems appropriate, provide for other perquisites or benefits in a manner the Company may determine in its sole discretion.

The Plan Administrator shall have the sole discretion to determine if a Covered Employee's employment by the Company has been subject to an Involuntary Termination. Any determination by the Plan Administrator regarding the nature of a Covered Employee's termination of his employment with the Company shall be final and binding. Payments provided herein shall be subject to any required tax withholding.

2.2  Termination Agreement and Release of all Claims. As a condition to receipt of any Severance Amount benefit hereunder, a Covered Employee whose employment by the Company has been subject to an Involuntary Termination will be required to execute a release agreement in the form established by the Company, releasing the Company, its shareholders, partners, officers, directors, employees and agents from any and all claims and from any and all causes of action of any kind or character, including but not limited to all claims or causes of action arising out of such Covered Employee's employment with the Company or the termination of such employment. Irrespective of a Covered Employee's execution of the required release agreement, the performance of the Company's obligations hereunder and the Covered Employee's receipt and acceptance of benefits provided hereunder by such Covered Employee shall constitute full settlement of all such claims and causes of action. If severance payments have been paid pursuant to the Plan to a Covered Employee whose employment by the Company was subject to an Involuntary Termination and such Covered Employee thereafter fails to comply in full with the terms of such release agreement, the release agreement shall remain valid and may be enforced by the Company, and such Covered Employee may be obligated to refund to the Company an amount equal to the excess of his Severance Amount over any payments received under Section 2.1(b) and the Company shall have the right to offset against any further monies or benefits owed to such Covered Employee (to the extent such offset is permissible under applicable law) the Severance Amount excess such Covered Employee is obligated to return to the Company.

2.3  Mitigation. A Covered Employee shall not be required to seek other employment or to otherwise engage in any mitigation effort to receive the benefit of any payment provided for in this Article II, nor shall the amount of any payment provided for in this Article II be reduced by any compensation or benefit earned by the Covered Employee as the result of employment by another employer or by retirement benefits.

2.4  Severance Offset. Any Severance Amount paid under this Plan will be reduced dollar-for-dollar by any severance pay, statutory benefits or pay in lieu of notice paid by the Company to a Covered Employee under applicable law or under any other plan or programs of the Company (including, without limitation, any arrangement providing for the payment of severance benefits to employees arising in connection with any acquisition, merger or other business combination to which the Company is a party and for which such Covered Employee is eligible).

III.

The Plan Administrator shall have all powers necessary or proper to administer the Plan and to discharge its duties under the Plan, including, but not limited to, the following powers:
