(a) During the Term the Executive will not directly or indirectly: (i) as an individual proprietor, partner stockholder, officer, employee, director, joint venturer, investor, lender, or in any other capacity whatsoever (other than as the holder of not more than one percent (1%) of the total outstanding stock of a publicly held company), engage in the business of developing, producing, marketing or selling products of the kind or type developed or being developed, produced, marketed or sold by the Company while the Executive was employed by the Company; or (ii) recruit, solicit or induce, or attempt to induce, any employee or employees of the Company to terminate their employment with, or otherwise cease their relationship with, the Company; or (iii) solicit, divert or take away, or attempt to divert or to take away, the business or patronage of any of the clients, customers or accounts, or prospective clients, customers or accounts, of the Company which were contacted, solicited or served by the Executive while employed by the Company.

(c) The restrictions contained in this Section 6.3 are necessary for the protection of the business and goodwill of the Company and are considered by the Executive to be reasonable for such purpose. The Executive agrees that any breach of this Section 6.3 will cause the Company substantial and irrevocable damage and therefore, in the event of any such breach, in addition to such other remedies which may be available, the Company shall have the right to seek specific performance and injunctive relief. 7 7.
