Executive shall not, except as required by law or regulation or in the ordinary course of performance of his duties as an employee of the Company, intentionally disclose, or use during the term of his employment and thereafter any Proprietary Information. By way of illustration but not limitation, Proprietary Information includes customer, prospective customer and data, records, computer programs, manuals, processes or methods and intangible rights which are either developed by Executive during the term of his employment or to which Executive has access, which development or access was rendered possible by virtue of Executive’s employment, and which is not generally known to and not

7

readily ascertainable through proper means other than the Company, by other firms in the business.

(c) Memoranda, etc. Executive acknowledges and agrees that all memoranda, notes, reports, records and other documents made or compiled by Executive, or made available to Executive during the term of employment concerning the business of the Company or any of its subsidiaries, shall be the Company’s property and shall be delivered to the Company upon the termination of Executive’s employment, hereunder. Following the expiration or termination of Executive’s employment hereunder, Executive agrees to cooperate with reasonable advance notice and at mutually convenient times, for a period of five (5) years with respect to legal matters and for a period of one (1) year with respect to all other matters, with the Company and its subsidiaries with respect to matters with which Executive was involved during the term of his employment. The Executive will be reimbursed for reasonable expenses incurred by the Executive if Company requires travel.

(d) Survival. The provisions of this Section 6 shall survive the termination or expiration of this Agreement and Executive’s term of employment.
