         Fifty Thousand Dollars ($550,000) per year.  Such base salary shall be
         subject to adjustment from time to time (but, with respect to any
         adjustment to be made applicable to an upcoming calendar year, such
         adjustment shall not be made later than October of the year prior to
         such upcoming year), as determined by the Compensation Committee of

         Committee")."

    (b)  Section 3.2 (a) of the Agreement shall be deleted in its entirety and
         the following shall be inserted in lieu thereof:

         "The Employee shall be eligible to receive a minimum bonus ("target
         bonus") of Three Hundred Fifty Thousand Dollars ($350,000) following
         the end of each calendar year beginning with 2001, based on the
         achievement of performance objectives (based primarily on revenue,
         operating profit and cash flow objectives or other mutually agreeable
         objectives) to be mutually agreed upon by the Employee and the
         Compensation Committee. Such target bonus shall be subject to

         made applicable to an upcoming calendar year, such adjustment shall not
         be made later than October of the year prior to such upcoming year), as

         of Thirty Thousand Dollars ($30,000) in each of March, June, September
         and December. The balance of the target bonus for each year, if any,
         shall be paid at the conclusion of the audit for such year (typically
         within sixty (60) days after the end of the year). The Compensation
         Committee may, in its discretion, award and pay a bonus in addition to
         the target bonus."

               the Company;

               iii.  Subject to Sub-Section iv hereof, the Company shall pay the
               Employee the payment described in this Section (the "Severance
               Payment").  In lieu of any further salary payments to the
               Employee for periods subsequent to the occurrence of a Change in
               Control and in lieu of any severance benefit otherwise payable to
               the Employee, the Company shall pay to the Employee a lump sum
               severance payment, in cash, equal to the sum of 2.99 times his
               annual base salary and 2.99 times his target bonus at 100%
               performance.

               iv.   In the event that the Employee's Total Payments (not
               including the Gross-Up Payment), as hereinafter defined, are
               subject in whole or in part to the excise tax imposed under
               Section 4999 of the Code (the "Excise Tax"), then the Company
               shall pay to the Employee an additional amount (the "Gross-Up
               Payment") such that the net amount retained by the Employee after
               payment of any Excise Tax on the Total Payments and any federal,
               state and local income taxes on the Gross-Up Payment equals the
               Total Payments, (not including the Gross-Up Payment).

               v.    For purposes of determining whether and the extent to which
               the Total Payments will be subject to the Excise Tax, (1) no
               portion of the Total Payments the receipt or enjoyment of which
               the Employee shall have effectively waived in writing prior to
               the occurrence of a Change in Control  shall be taken into
               account, (2) no portion of the Total Payments shall be taken into
               account which in the opinion of tax counsel selected by the
               Company does not constitute a "parachute payment" within the

                                       3
<PAGE>

               meaning of Section 280G(b) (2) of the Code, (including by reason
               of Section 280G(b) (4) (A) of the Code) and, in calculating the
               Excise Tax, no portion of such Total Payments shall be taken into
               account which constitutes reasonable compensation for services
               actually rendered, within the meaning of Section 280G(b) (4) (B)
               of the Code, in excess of the Base Amount allocable to such
               reasonable compensation, and (3) the value of any non-cash
               benefit or any deferred payment or benefit included in the Total
               Payments shall be determined by the Company in accordance with
               the principles of Sections 280G(d) (3) and (4) of the Code.

               vi.   For purposes of determining the amount of the Gross-Up
               Payment, the Employee shall be deemed to pay federal income taxes
               at the highest marginal rate of federal income taxation in the
               calendar year in which the Gross-Up Payment is to be made and
               state and local income taxes at the highest marginal rate of
               taxation in the state and locality of the Employee's residence on
               the Date of Termination.

               vii.  For purposes of this Agreement, "Total Payments" means any
               payment or benefit received or to be received by the Employee in
               connection with a Change in Control or the termination of the
               Employee's employment, whether pursuant to the terms of this
               Agreement or any other plan, arrangement, or agreement with (1)
               the Company, (2) any person whose actions result in a Change in
               Control, or (3) any person affiliated with the Company or the
               person whose actions resulted in a Change in Control. Total
               Payments includes, but is not limited to the Severance Payment
               and the Gross-Up Payment.

               viii. For the purpose of this Agreement, "Base Amount" shall have
               the meaning defined in section 280G(b)(3) of the Code.

               ix.   The Severance Payment and the Gross-Up Payment, if any,
               shall be made not later than the fifth day following  a Change in
               Control, provided, however, that if the amount of such payments
               cannot be finally determined on or before such day, the Company
               shall pay to the Employee on such day an estimate, as determined
               in good faith by the Company, of the minimum amount of such
               payments to which the Employee is clearly entitled.  In the event
               that the Excise Tax is subsequently determined to be less than
               the amount taken into account in originally computing the Gross-
               Up Payment, the Employee shall repay to the Company at the time
               that the amount of such reduction in Excise Tax is finally
               determined the portion of the Gross-Up Payment attributable to
               such reduction (plus the portion of the Gross-Up Payment
               attributable to the Excise Tax imposed on the Gross-Up Payment
               being repaid by the Employee if such repayment results in a
               reduction in Excise Tax).  In the event that the Excise Tax is
               determined to exceed the amount taken into account in originally
               computing the Gross-Up Payment (including any increase as the
               results of any payment which cannot be determined, or did not
               exist, at the time of the original computation), the Company
               shall recalculate the Gross-Up

                                       4
<PAGE>

               Payment and pay the additional amount to the Employee at the time
               that such additional amount in finally determined.

               x.    Prior to the payment date set forth in Sub-Section ix, the
               Company shall provide the Employee with the Company's calculation
               of the Total Payments and the Gross-Up Payments, if any, and such
               supporting materials as are reasonably necessary for the Employee
               to evaluate the Company's calculations, including, without
               limitation, any opinions or other advice the Company has received
               from outside counsel, auditors or consultants (and any such
               opinions or advice which are in writing shall be attached to the
               statement)."

2.   The parties hereto acknowledge that:

     (a)  on November 16, 2000, the Compensation Committee authorized the
          Company to issue and sell to the Employee 120,000 restricted shares of
          the Company's Common Stock at a price of $.01 per share, and that a
          form of such Restricted Stock Agreement is attached hereto as, and is
          subject to the terms set forth in, Exhibit B; and

     (b)  on  November 16, 2000, the Compensation Committee authorized the
          Company to issue and sell to the Employee 120,000 restricted shares of
          the Company's Common Stock at a price of $.01 per share, and that a
          form of such Restricted Stock Agreement is attached hereto as, and is
          subject to the terms set forth in, Exhibit C.

     (c)  for the avoidance of doubt, that Paragraph 3(g) (regarding exercise
          period upon death or disability) of that certain non-qualified stock
          option granted to the Employee on (i) February 4, 1997 exercisable for
          1,000,000 shares of the Company's Common Stock, and (ii) October 21,
          1999 exercisable for 300,000 shares of the Company's Common Stock
          (collectively, the "1997 and 1999 Options"), is hereby clarified to
          provide that if the Employee dies or becomes disabled during a vesting
          continuation period under Section 5 of the Agreement, with respect to
          only such portion of the 1997 and 1999 Options that become exercisable
          by the Employee during such period, if any, such options shall be
          exercisable by the Employee or by the person to whom such options are
          transferred by will or the laws of descent and distribution for a
          period of one year following the cessation of vesting (but in no event
          after any applicable option expiration date).

     (d)  for the avoidance of doubt, that discharge for "cause" under Paragraph
          3(h) of the 1997 and 1999 Options shall not mean the Employee's death
          or disability.

3.   To the extent any provision of this Amendment is inconsistent with any
provision of the Agreement and/or prior amendments, such provision of the
Agreement is hereby modified and superseded by the terms hereof.  Any term of
the Agreement not so modified or superseded shall remain in full force and
effect.  For the avoidance of doubt, and without limiting the generality of the
foregoing, Sections 1(a) and 1(b) of this Amendment supersede in their entirety
Sections 1(a) and 1(b) of Amendment No. 3 to the Agreement, respectively.

     EXECUTED as of the date first set forth above.
