The Company agrees to use reasonable efforts to ensure that its “named executive officers”, as such term is defined under Item 402 of Regulation S-K promulgated by the Securities and Exchange Commission will not make, to any third party any disparaging, untrue, or misleading written or oral statements about or relating to Executive. The foregoing provision shall not be effective with respect to any information required to be disclosed by the Executive, Company or named executive officers by the order of a court or administrative agency, subpoena or other legal or administrative demand, or as permitted within Paragraph 8.

8.Permitted Activities. Notwithstanding any other provision of this Agreement or the Employment Agreement, nothing in this Agreement is intended to, or does, preclude Executive from (i) contacting, reporting to, responding to an inquiry from, filing a charge or complaint with, communicating with, or otherwise participating in an investigation conducted by, the EEOC, the Department of Labor, 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, commission, or regulatory body; (ii) giving truthful testimony or making statements under oath in response to a subpoena or other valid legal process or in any legal proceeding; (iii) otherwise making truthful statements as required by law or valid legal process; (iv) engaging in any concerted or other legally protected activities; or (v) disclosing a trade secret in confidence to a governmental official, directly or indirectly, or to an attorney, if the disclosure is made solely for the purpose of reporting or investigating a suspected violation of law.

The Executive likewise understands that, if the Executive files a lawsuit for retaliation by the Company for reporting a suspected violation of law, the Executive may disclose the Company’s

trade secret(s) to his attorney and use the trade secret information in the court proceeding, if the Executive (i) files any document containing the trade secret under seal; and (ii) does not disclose the trade secret, except pursuant to court order.

If any provision of this Agreement shall be found by a court of competent jurisdiction to be invalid or unenforceable, in whole or in part, then such provision shall be construed and/or modified or restricted to the extent and in the manner necessary to render the same valid and enforceable, or shall be deemed excised from this Agreement, as the case may require, and this Agreement shall be construed and enforced to the maximum extent permitted by law, as if such provision had been originally incorporated herein as so modified or restricted, or as if such provision had not been originally incorporated herein, as the case may be. The parties further agree to seek a lawful substitute for any provision found to be unlawful; provided, that, if the parties are unable to agree upon a lawful substitute, the parties desire and request that a court or other authority called upon to decide the enforceability of this Agreement modify the Agreement so that, once modified, the Agreement will be enforceable to the maximum extent permitted by the law in existence at the time of the requested enforcement.
