As used in this Agreement, “members of the Farber Family” shall mean William Farber, his spouse and children and their respective spouses and children, all entities controlled by any of them and all trusts created by or for the benefit of any of them.

(ii)                             Company’s stockholders or Company’s Board of Directors shall approve (a) any consolidation or merger of Company in which Company is not the continuing or surviving corporation or pursuant to which Company’s voting common stock (the

5

(h)                            The termination of Executive’s employment with Company, for any reason and irrespective as to whether initiated by Executive or Company, shall be considered a contemporaneous resignation by Executive from the position of Company’s Vice President of Finance and Chief Financial Officer, and shall be deemed a termination from employment with all entities related to Company.

(i)                                Executive may terminate his employment hereunder at any time for any reason by giving Company prior written notice not less than thirty (30) days prior to such termination. Termination by Executive pursuant to this Clause shall be deemed a termination entitling Executive to compensation Pursuant to Section 9(e) above.

10.                                    Confidential Information. During Executive’s employment with Company and at all times after the termination of such employment, regardless of the reason for such termination, Executive shall hold all Confidential Information relating to Company in strict confidence and in trust for Company and shall not disclose or otherwise communicate, provide or reveal in any manner whatsoever any of the Confidential Information to anyone other than Company without the prior written consent of Company. “Confidential Information” includes, without limitation, financial information, related trade secrets (including, without limitation, Company’s business plan, methods and/or practices) and other proprietary business information of Company which may include, without limitation, market studies, customer and client lists, referral lists and other items relative to the business of Company. “Confidential Information” shall not include information which is or becomes in the public domain through no action by Executive or information which is generally disclosed by Company to third parties without restrictions on such third parties.

11.                                    Solicitation of Customers. During his employment with Company and for a period of eighteen (18) months after the termination of Executive’s employment, regardless of the reason for the termination (the “Non-Competition Period”), Executive shall not, whether directly or indirectly, for his own benefit or for the benefit of any other person or entity, or as a partner, stockholder, member, manager, officer, director, proprietor, employee, consultant, representative, agent of any entity other than Company, solicit, directly or indirectly, any customer of Company, or induce any customer of Company to terminate any association with Company, in connection with those certain products being offered for sale by Company or in its research and development pipeline on the date of termination of Executive’s employment (the “Restricted Products”) or otherwise attempt to provide services to any customer of Company in connection with the Restricted Products. Executive shall prevent such solicitation to the extent he has authority to prevent same and otherwise shall not interfere with the relationship between Company and its customers. This provision shall not be interpreted to prohibit, prevent or otherwise impair the Executive’s ability and right to seek and obtain employment from a competitor of Company, even if said competitor is currently selling products to Company’s customers that are the same as Company products. While the Executive

6

shall be unrestricted in seeking to sell products to Company’s customers that are different than Company’s products, it is the intent of this paragraph to preclude the Executive from having said competitor replace Company as a supplier of a product or otherwise take existing sales from Company for the period in question.
