thereafter Executive shall not, directly or indirectly, either for Executive or
for any other person or entity, solicit any person or entity to terminate such
person's or entity's contractual and/or business relationship with the Company,
nor shall Executive interfere with or disrupt or attempt to interfere with or
disrupt any such relationship.  None of the foregoing shall be deemed a waiver
of any and all rights and remedies the Company may have under applicable law.

          III.4  Prohibition on Solicitation of Employees, Agents or Independent
                 ---------------------------------------------------------------

                 ----------------------------------------              
obligations not to disclose or use Confidential Information and to refrain from
the solicitations described in this Article III are of a special and unique
character which gives them a peculiar value.  The Company cannot be reasonably
or adequately compensated for damages in an action at law in the event Executive
breaches such obligations.  Therefore, Executive expressly agrees that the
Company shall be entitled to injunctive and other equitable relief without bond
or other security in the event of such breach in addition to any other rights or
remedies which the Company may possess or be entitled to pursue.  Furthermore,
the obligations of Executive and the rights and remedies of the Company under

obligations, rights, or remedies created by applicable law relating to
misappropriation or theft of trade secrets or Confidential Information.

          III.6  Survival of Obligations.  Executive agrees that the terms of
                 -----------------------

     within ninety (90) days of the beginning of the new period of incapacity or
     absence and the incapacity or absence is determined by the Company's Board

          then Base Salary for a period equal to one month for each full year

               (e) In the event Executive's employment is terminated for Good
     Reason pursuant to either Sections 4.1(b)(v) or 4.1(b)(vi), then in
     addition to those payments required by Section 4.5(b) above, the Company
     shall also provide to Executive a lump sum payment within thirty (30) days
     of the Effective Date equal to twice Executive's Base Salary, or $500,000.

               (f) This Section 4.5(f) is intended to put Executive in the same
     economic position as Executive would have had no Section 4999 Taxes and
     Expenses (as defined below) been imposed upon or incurred as a result of
     any payment, distribution,

                                       6
<PAGE>
 
     benefit or transfer (each a "Payment" and collectively the "Payments") made
     pursuant to the terms of this Agreement or otherwise. In the event it is
     determined that any Payments to or for the benefit of Executive is or was
     subject to the excise tax imposed by Section 4999 of the Internal Revenue
     Code of 1986, as amended, any successor provision, or any comparable
     provision of state or local income tax law, or any interest, penalties,

     to any such excise taxes (such taxes, penalties, interest, additions to tax
     and costs (including professional fees) are hereinafter referred to as

     determination, the Company shall pay to Executive an additional cash
     payment, which after payment of or withholding for any taxes (including,
     without limitation, any excise and income taxes), interest, penalties,
     additions to tax or costs imposed or incurred with respect to such
     additional cash payment, is equal to the Section 4999 Taxes and Expenses.
     The determination that a Payment is subject to Section 4999 Taxes and
     Expenses shall be made in writing by a certified public accounting firm
     selected by Executive.
