6.    No Other Payments or Benefits. All other benefits not described in this Agreement shall cease as of the Separation Date; provided that nothing in this Agreement shall be interpreted in a manner which would require Executive to forfeit benefits that were vested as of the Separation Date. Executive acknowledges and agrees that, other than the payments and benefits expressly set forth in this Agreement, Executive has received all compensation and amounts to which he is entitled from the Company, and Executive is not entitled to any other payments or benefits from the Company.

8.    Company Property. All records, files, lists, including computer generated lists, data, drawings, documents, equipment and similar items relating to the Company’s business that Executive generated or received from the Company remains the Company’s sole and exclusive property. Promptly after the Separation Date, Executive shall return to the Company all property of the Company in his possession. Executive further represents that he has not copied or caused to be copied, printed out, or caused to be printed out any documents or other material originating with or belonging to the Company, except in the good faith performance of his job duties for the Company. Executive additionally represents that he will not retain in his possession any such documents or other materials.

(a)    Executive waives any and all claims and hereby releases and forever discharges the Company and each and all of its current and former affiliated business entities, parent or sister corporations, subsidiaries, predecessors, successors, affiliates, assigns, partners, insurers, guarantors, shareholders, board members, and each and all of their officers, directors, representatives, employees, agents, attorneys and other representatives (the “Company Released Parties”) from any and all claims and causes-of-action, charges, complaints, liabilities, obligations, promises, agreements, damages, actions, suits, rights, demands, losses, debts, costs and expenses of any nature whatsoever, whether known or unknown, suspected or unsuspected, disclosed or undisclosed, contingent or absolute, matured or unmatured, whether brought individually, as a member or representative of a class, or derivatively on behalf of the Company or shareholders of the Company, arising prior to the date on which this Release is executed as reflected on the signature page hereof (the “Release Execution Date”), which Executive ever had, now has or may hereafter have against the Company Released Parties with respect to or connected with his employment with the Company or the termination thereof or Executive’s service as an officer or director of the Company or its affiliates or the termination of such service, including, but not limited to, any and all matters related in any way to Executive’s resignation or separation from the Company, Executive’s ownership of Company stock, and any claims or causes-of-action under Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1866, 42 U.S.C. § 1981, the Americans With Disabilities Act of 1990, the Age Discrimination in Employment Act, the Older Workers Benefit Protection Act, the Civil Rights Act of 1991, the Family Medical Leave Act of 1993, the Employee Retirement Income Security Act of 1974, and any other federal, state or local anti-discrimination or anti-retaliation laws, and any other statutory, contractual, or tort, or equitable claims related in any manner to Executive’s employment, resignation from employment with the Company or his status as a shareholder of the Company with respect to occurrences arising on or prior to the Separation Date (collectively the “Released Claims”). This Release is intended to have the broadest possible application and includes, but is not limited to, any tort, contract, common law, constitutional or other statutory claims unless otherwise expressly provided herein. Subject to Section 9(b) below, Executive agrees to waive the right to receive future monetary recovery directly from the Company, including Company payments that result from any complaints or charges that Executive files with any governmental agency or that are filed on Executive’s behalf (including but not limited to reinstatement to employment).

If it is determined that any Released Claim cannot be waived

under applicable legal requirements, Executive expressly agrees that this Release will nevertheless remain valid and fully enforceable as to the remaining Released Claims. In addition to the foregoing and notwithstanding anything herein to the contrary, Executive understands that nothing contained in this Agreement limits Executive’s ability to file a charge or complaint for possible violations of law or regulation to any federal, state or local governmental agency or entity, including, but not limited to, the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission or any other federal, state or local governmental agency or commission (“Government Agencies”). Executive further understands this Release does not limit Executive’s ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. This Release does not limit Executive’s right to receive an award from any Government Agency for information provided to any Government Agencies.

(c)    By signing this Release, Executive understands that he voluntarily and knowingly waives any and all of his rights or claims under the federal Age Discrimination in Employment Act of 1967 (ADEA), as amended, that may have existed prior to the date he signs this Release. However, Executive is not waiving any future rights or claims under the ADEA or Title VII of the Civil Rights Act for actions arising after the date he signs this Release. Executive further acknowledges that he is not waiving his right to challenge the effectiveness of this Release with respect to his claims under the ADEA.

(d)    Executive understands that he is releasing Released Claims that he may not know about, and that is his knowing and voluntary intent.

This Agreement may be amended or modified only by an agreement in writing, signed by both Parties.

It is intended that any amounts payable under this Agreement will be exempt from or comply with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and Treasury Regulations relating thereto, and this Agreement shall be interpreted and construed accordingly; provided, however, that the Company and its subsidiaries and affiliates shall not be responsible for any taxes, penalties, interest or other losses or expenses incurred by Executive due to any failure to comply with Section 409A of the Code. Each payment under this Agreement as a result of the separation of Executive’s service shall be considered a separate payment for purposes of Section 409A of the Code.

Any payments delayed pursuant to this Section 14 shall be made in a lump sum on the first day of the seventh month following Executive’s “separation from service” (as such term is defined under Treasury Regulation 1.409A-1(h)) or, if sooner, the date of Executive’s death.

Facsimile and electronic signatures shall, for all purposes, be treated as originals.
