<PAGE>

             6.1(b) During the term of this Agreement and, the Consultant shall
             not, directly or indirectly, (i) induce or attempt to influence any
             executive of THE COMPANY to leave its employ, (ii) aid or agree to
             aid any competitor, customer or supplier of THE COMPANY in any

             business entity who was a customer or supplier of THE COMPANY
             during any portion of said period to transact business with a
             competitor of THE COMPANY in Company's business.

             6.1(c) During the Term of this Agreement and thereafter, the
             Consultant shall not disclose to anyone any information about the
             affairs of THE COMPANY, including, without limitation, trade
             secrets, trade "know-how", inventions, customer lists, business
             plans, operational methods, pricing policies, marketing plans,
             sales plans, identity of suppliers or customers, sales, profits or
             other financial information, which is confidential to THE COMPANY
             or is not generally known in the relevant trade, nor shall the
             Consultant make use of any such information for his own benefit.

      6.2 If the Consultant breaches, or threatens to commit a breach of Section
      6.1 (the "Restrictive Covenants"), THE COMPANY shall have the following
      rights and remedies, each of which shall be enforceable, and each of which
      is in addition to, and not in lieu of, any other rights and remedies
      available to THE COMPANY at law or in equity.

             6.2(a) The Consultant shall account for and pay over to THE COMPANY
             all compensation, profits, and other benefits, after taxes, which
             inure to Consultant's benefit which are derived or received by the
             Consultant or any person or business entity controlled by the
             Consultant resulting from any action or transactions constituting a
             breach of any of the Restrictive Covenants. 6.2(b) Notwithstanding
             the provisions of subsection 6.2(a) above, the Consultant
             acknowledges and agrees that in the event of a violation or
             threatened violation of any of the provisions of Section 6.1, THE
             COMPANY shall have no adequate remedy at law and shall therefore be
             entitled to enforce each such provision by temporary or permanent
             injunctive or mandatory relief obtained in any court of competent
             jurisdiction without the necessity of proving damages, posting any
             bond or other security, and without prejudice to any other rights
             and remedies which may be available at law or in equity.

      6.3 If any of the Restrictive Covenants, or any part thereof, is held to
      be invalid or unenforceable, the same shall not affect the remainder of
      the covenant or covenants, which shall be given full effect, without
      regard to the invalid or unenforceable portions. Without limiting the
      generality of the foregoing, if any of the Restrictive Covenants, or any
      part thereof, is held to be unenforceable because of the duration of such
      provision or the area covered thereby, the parties hereto agree that the
      court making such termination shall have the power to reduce the duration
      and/or area of such provision and, in its reduced form, such provision
      shall then be enforceable.

                                       3
<PAGE>

      6.4 The parties hereto intend to and hereby confer jurisdiction to enforce
      the Restrictive Covenants upon the courts of any jurisdiction within the
      geographical scope of such Restrictive Covenants. In the event that the
      courts of any one or more of such jurisdictions shall hold such
      Restrictive Covenants wholly unenforceable by reason of the breadth of
      such scope or otherwise, it is the intention of the parties hereto that
      such determination not bar or in any way affect THE COMPANY's right to the
      relief provided above in the courts of any other jurisdictions within the
      geographical scope of such Restrictive Covenants, as to breaches of such
      covenants in such other respective jurisdictions, the above covenants as
      they relate to each jurisdiction being, for this purpose, severable into
      diverse and independent covenants.

7)    MISCELLANEOUS.
