           ---------------------
Operating Officer of the Company, reporting to the President, and shall have
such powers and duties as may from time to time be prescribed by the committee,

private office, secretarial and administrative assistance, office equipment,
supplies and other facilities and services suitable to the Executive's position.

(the "Base Salary") at an annual rate of $150,000.00 per year during the Initial
Term, payable in accordance with the Company's payroll practices in effect from
time to time, and at a rate set by the compensation committee of the Company's
committee of directors for any Additional Term. Any increase in Base Salary or

year of the Initial Term, the bonus payments to Executive will be no less than
$50,000 as set forth in Section 4(a)(i) and (ii) hereof shall be in lieu of his
participation in any other incentive bonus programs that have been or may be

discretion of the Company's committee of directors, the Executive may be awarded
for each calendar year during the remainder of the Initial Term and any
subsequent Additional Term, an annual bonus (an "Annual Bonus") either pursuant
to a bonus or incentive plan of the Company or otherwise on terms no less
favorable than those awarded to other executive officers of the Company.

     (b) The Company agrees to grant to Executive options to purchase 500,000
shares of the common stock, no par value, of the Company at an option exercise
price equal to $1.00 per share (the "Discounted Stock Options").  Such options

committee of directors, and the terms of the grant shall provide, among other
things, (i) that 50% of the Discounted Stock Options so granted shall vest and
become exercisable on the first anniversary date of grant and thereafter,50%

Discounted Stock Options to be granted pursuant hereto are in lieu of any other
stock option or stock incentive

                                       2
<PAGE>

plans or programs that may be granted or extended to other executive officers of
the Company during the Initial Term.

     5.   Benefits. The Executive shall be entitled to all benefits and
          --------
conditions of employment provided by the Company to its executive officers,
including, without limitation, insurance, participation in the Company's
vacation policy, and participation in (except during the Initial terms as
described in Section 4 hereof) any stock option or incentive compensation plans,

terms of such plans and any provisions, rules, regulations and laws applicable
to such plans. In exception, Executive will be entitled to a minimum of 4 weeks
vacation annually, nonaccruing.

     6.   Reimbursement for Business Expenses. The Executive shall be reimbursed
          -----------------------------------
for all reasonable out-of-pocket business expenses incurred by him in the direct
performance of his duties during his employment with the Company pursuant to the

from time to time. All requests for reimbursement shall be substantiated by
invoices and other pertinent data reasonably satisfactory to the Company.

     7.   Performance. The Executive shall devote all of his working time and
          -----------
efforts to the business and affairs of the Company and to the diligent, faithful
and competent performance of the duties and responsibilities assigned to him
pursuant to this Agreement, except for vacations, weekends and holidays.
Notwithstanding the foregoing, the Executive may render charitable, civic and
outside committee services so long as such services do not materially interfere
with the Executive's ability to discharge his duties, including, without
limitation, such outside services as the Executive is currently performing.

     8.   Non-Disclosure of Proprietary Information; Non-Competition; Non-
          ---------------------------------------------------------------
Solicitation.
------------

               8.1. Confidential Information; Trade Secrets. As used in this
                    ---------------------------------------
          Agreement, the term "Confidential Information" shall mean valuable,
          non-public, competitively sensitive data and information relating to
          the Company's business or the business of any entity affiliated with
          the Company, other than Trade Secrets (as defined below).
          "Confidential Information" shall include, among other things,
          information specifically designated as a Trade Secret that is,
          notwithstanding the designation, determined by a court of competent
          jurisdiction not to be a "trade secret" under applicable law. As used
          in this Agreement, the term "Trade Secrets" shall mean information or
          data of or about the Company or any entity affiliated with the
          Company, including, without limitation, technical or non-technical
          data, formulas, patterns, compilations, programs, devices, methods,
          techniques, drawings, processes, financial data, financial plans,
          product plans, or lists of actual or potential customers or suppliers,
          that (i) derive economic value, actual or potential, from not being
          generally known to, and not being readily ascertainable by proper
          means by, other persons who can obtain economic value

                                       3
<PAGE>

          from their disclosure or use; and (ii) are subject of efforts that are
          reasonable under the circumstances to maintain their secrecy. To the
          extent that the foregoing definition is inconsistent with a definition
          of "trade secret" under applicable law, the foregoing definition shall
          be deemed amended to the extent necessary to render it consistent with
          applicable law.

               8.2. Non-Disclosure. The Executive will be exposed to Trade
                    --------------
          Secrets and Confidential Information as a result of his employment by
          the Company as provided in this Agreement. The Executive acknowledges
          and agrees that any unauthorized disclosure or use of any of the Trade
          Secrets or Confidential Information of the Company would be wrongful
          and would likely result in immediate and irreparable injury to the
          Company. In consideration of the Executive's right to employment (or
          continued employment) under the terms of this Agreement, except as
          appropriate in connection with the performance of his obligations
          under this Agreement, the Executive shall not, without the express
          prior written consent of an officer of the Company other than the
          Executive, redistribute, market, publish, disclose or divulge to any
          other person or entity, or use or modify for use, directly or
          indirectly, in any way for any person or entity (i) any Confidential
          Information during the Term of this Agreement and for a period of two
          (2) years after the final date of the Term of this Agreement; and (ii)
          any Trade Secrets at any time (during or after the Term of this
          Agreement) during which such information or data shall continue to
          constitute a "trade secret" under applicable law. The Executive agrees
          to cooperate with any reasonable confidentiality requirements of the
          Company. The Executive shall immediately notify the Company of any
          unauthorized disclosure or use of any Trade Secrets or Confidential
          Information of which the Executive becomes aware.

               8.3. Non-Competition. The Executive shall not, either directly or
                    ---------------
          indirectly, alone or in partnership, be connected or concerned with or
          participate in any other competing business or pursuit during any
          employment by the Company, except that the Executive may own up to
          three percent of the outstanding securities of a competing business
          the securities of which are registered with the Securities and
          Exchange Commission if such company is subject to the periodic
          reporting requirements of the Securities Exchange Act of 1934, as
          amended (the "1934 Act").

               8.4. Non-Solicitation. For a period of one (1) year immediately
                    ----------------
          following any termination of the Executive's employment, the Executive
          will not solicit, or participate in any solicitation of, the
          customers, suppliers, Executives or representatives of the Company (or
          any of its subsidiaries or affiliated companies) to breach any
          contract with the Company, terminate any relationship with the Company
          or leave the Company. For purposes of this Agreement, customers shall
          be limited to actual customers or actively-sought prospective
          customers of the Company or any subsidiary or affiliate of the Company
          with whom the

                                       4

                    -----------
          shall mean the Executive's annual Base Salary at the highest rate in
          effect on, or at any time during the ninety (90) day period prior to,
          the Termination Date and shall include all amounts of the Executive's
          Base Salary that are deferred under any qualified and non-qualified

          good faith by two-thirds (2/3) of the Company's committee of directors
          that the Executive (i) intentionally and continually failed
          substantially to perform his reasonably assigned duties with the
          Company (other than a failure resulting from the Executive's
          incapacity due to physical or mental illness or from the Executive's
          assignment of duties that would constitute "Good Reason" (as
          hereinafter defined)) which failure continued for a period of at least
          thirty (30) days after a written notice of demand for substantial
          performance has been delivered to the Executive specifying the manner
          in which the Executive has failed substantially to perform, or (ii)

          results in material economic harm to the Company; provided, however,
                                                            --------  -------
          that no termination of the Executive's employment shall be for Cause

          person by the Company's committee of directors (with the assistance of
          the Executive's counsel if the Executive so desires). Any termination
          of the Executive's employment by the Company hereunder shall be deemed
          to be a termination other than for Cause unless it meets all
          requirements of this Section 9.3.

          or, if there be no such designee, to the Executive's estate.

     13.  Injunctive Relief. The Company and the Executive agree that damages

time to time, and at a rate set by the compensation committee of the Company's
committee of directors for any Additional Term. Any increase in Base Salary or
other compensation granted by the compensation committee of the Company's
committee of directors shall in no way limit or reduce any other obligation of
the Company hereunder. Once established at an increased specified rate, the term
Base Salary used in this Agreement shall refer to the Base Salary as so
increased.

     4.   Bonus and Special Option Award.
          ------------------------------

     (a)  In addition to his Base Salary, upon completion of the first year of
the Initial Term, Executive shall receive (i) a special bonus equal to no less
than 50% of Base Salary and no more than 100% of Base Salary, payable on the
first anniversary of Executive's employment with the Company; provided the
Executive achieves each of the performance objectives.  Thereafter, in the
discretion of the Company's committee of directors, the Executive may be awarded
for each calendar year during the remainder of the Initial Term and any
subsequent Additional Term, an annual bonus (an "Annual Bonus") either pursuant
to a bonus or incentive plan of the Company or otherwise on terms no less
favorable than those awarded to other executive officers of the Company.

     (b)  The Company agrees to grant to Executive options to purchase 500,000
shares of the common stock, no par value, of the Company at an option exercise
price equal to $1.00 per share (the "Stock Options").  Such options shall be
issued to Executive pursuant to a plan to be adopted by the Company's committee
of directors, and the terms of the grant shall provide, among other things, (i)
that 50% of the Stock Options so granted shall vest and become exercisable on
the first anniversary date of grant and thereafter, 50% shall vest as of the
last day of each succeeding calendar year following the date of grant until all
such options shall be fully vested; and (ii) the Stock Options may be exercised,
once vested, up to ten years following the date of grant.  Executive
acknowledges and agrees that the Stock Options to be granted pursuant hereto are
in lieu of any other stock option or stock incentive plans or programs that may
be granted or extended to other executive officers of the Company during the
Initial Term.

     5.   Benefits. The Executive shall be entitled to all benefits and
          --------

described in Section 4 hereof) any stock option or incentive compensation plans,
pension, profit sharing or other retirement plans, subject (in each case) to the
terms of such plans and any provisions, rules, regulations and laws applicable
to such plans. In exception, Executive will be entitled to a minimum of 4 weeks
vacation annually, nonaccruing.

     6.   Reimbursement for Business Expenses. The Executive shall be reimbursed
          -----------------------------------
for all reasonable out-of-pocket business expenses incurred by him in the direct
performance of his duties during his employment with the Company pursuant to the
terms of this Agreement and in accordance with the Company's policies in effect
from time to time. All requests for reimbursement shall be substantiated by
invoices and other pertinent data reasonably satisfactory to the Company.

     7.   Performance.  The Executive shall devote all of his working time and
          -----------
efforts to the business and affairs of the Company and to the diligent, faithful
and competent performance of the duties and responsibilities assigned to him
pursuant to this Agreement, except for vacations, weekends and holidays.
Notwithstanding the foregoing, the Executive may render charitable, civic and
outside committee services so long as such services do not materially interfere
with the Executive's ability to discharge his duties, including, without
limitation, such outside services as the Executive is currently performing.

     8.   Non-Disclosure of Proprietary Information; Non-Competition; Non-
          ---------------------------------------------------------------
Solicitation.
------------

               8.1.  Confidential Information; Trade Secrets. As used in this
                     ---------------------------------------
          Agreement, the term "Confidential Information" shall mean valuable,
          non-public, competitively sensitive data and information relating to
          the Company's business or the business of any entity affiliated with
          the Company, other than Trade Secrets (as defined below).
          "Confidential Information" shall include, among other things,
          information specifically designated as a Trade Secret that is,
          notwithstanding the designation, determined by a court of competent
          jurisdiction not to be a "trade secret" under applicable law. As used
          in this Agreement, the term "Trade Secrets" shall mean information or
          data of or about the Company or any entity affiliated with the
          Company, including, without limitation, technical or non-technical
          data, formulas, patterns, compilations, programs, devices, methods,
          techniques, drawings, processes, financial data, financial plans,
          product plans, or lists of actual or potential customers or suppliers,
          that (i) derive economic value, actual or potential, from not being
          generally known to, and not being readily ascertainable by proper
          means by, other persons who can obtain economic value from their
          disclosure or use; and (ii) are subject of efforts that are reasonable
          under the circumstances to maintain their secrecy. To the extent that
          the foregoing definition is inconsistent with a definition of "trade
          secret" under

                                       3
<PAGE>

          applicable law, the foregoing definition shall be deemed amended to
          the extent necessary to render it consistent with applicable law.

8.2.  Non-Disclosure.  The Executive will be exposed to Trade Secrets and
      --------------
          Confidential Information as a result of his employment by the Company
          as provided in this Agreement.  The Executive acknowledges and agrees
          that any unauthorized disclosure or use of any of the Trade Secrets or
          Confidential Information of the Company would be wrongful and would
          likely result in immediate and irreparable injury to the Company.  In
          consideration of the Executive's right to employment (or continued
          employment) under the terms of this Agreement, except as appropriate
          in connection with the performance of his obligations under this
          Agreement, the Executive shall not, without the express prior written
          consent of an officer of the Company other than the Executive,
          redistribute, market, publish, disclose or divulge to any other person
          or entity, or use or modify for use, directly or indirectly, in any
          way for any person or entity (i) any Confidential Information during
          the Term of this Agreement and for a period of two (2) years after the
          final date of the Term of this Agreement; and (ii) any Trade Secrets
          at any time (during or after the Term of this Agreement) during which
          such information or data shall continue to constitute a "trade secret"
          under applicable law.  The Executive agrees to cooperate with any
          reasonable confidentiality requirements of the Company.  The Executive
          shall immediately notify the Company of any unauthorized disclosure or
          use of any Trade Secrets or Confidential Information of which the
          Executive becomes aware.

8.3.  Non-Competition.  The Executive shall not, either directly or indirectly,
      ---------------
          alone or in partnership, be connected or concerned with or participate
          in any other competing business or pursuit during any employment by
          the Company, except that the Executive may own up to three percent of
          the outstanding securities of a competing business the securities of
          which are registered with the Securities and Exchange Commission if
          such company is subject to the periodic reporting requirements of the
          Securities Exchange Act of 1934, as amended (the "1934 Act").

8.4.  Non-Solicitation.  For a period of one (1) year immediately following any
      ----------------
          termination of the Executive's employment, the Executive will not
          solicit, or participate in any solicitation of, the customers,
          suppliers, Executives or representatives of the Company (or any of its
          subsidiaries or affiliated companies) to breach any contract with the
          Company, terminate any relationship with the Company or leave the
          Company.  For purposes of this Agreement, customers shall be limited
          to actual customers or actively-sought prospective customers of the
          Company or any subsidiary or affiliate of the Company with whom the
          Executive has had substantial contact during the Term of this
          Agreement.

                     -----------
          shall mean the Executive's annual Base Salary at the highest rate in
          effect on, or at any time during the ninety (90) day period prior to,
          the Termination Date and shall include all amounts of the Executive's
          Base Salary that are deferred under any qualified and non-qualified
          Executive benefit plans of the Company or any other agreement or
          arrangement.

               9.3.  Cause. For purposes of this Agreement, a termination of
                     -----
          employment is for "Cause" if the Executive has been convicted of a
          felony or if the termination is evidenced by a resolution adopted in
          good faith by two-thirds (2/3) of the Company's committee of directors
          that the Executive (i) intentionally and continually failed
          substantially to perform his reasonably assigned duties with the
          Company (other than a failure resulting from the Executive's
          incapacity due to physical or mental illness or from the Executive's
          assignment of duties that would constitute "Good Reason" (as
          hereinafter defined)) which failure continued for a period of at least
          thirty (30) days after a written notice of demand for substantial
          performance has been delivered to the Executive specifying the manner
          in which the Executive has failed substantially to perform, or (ii)
          intentionally engaged in illegal conduct or gross misconduct which
          results in material economic harm to the Company; provided, however,
                                                            --------  -------
          that no termination of the Executive's employment shall be for Cause
          as set forth in clause (ii) above until (x) there shall have been
          delivered to the Executive a copy of a written notice setting forth
          that the Executive was guilty of the conduct set forth in clause (ii)
          and specifying the particulars thereof in detail, and (y) the
          Executive shall have been provided an opportunity to be heard in
          person by the Company's committee of directors (with the assistance of
          the Executive's counsel if the Executive so desires). Any termination
          of the Executive's employment by the Company hereunder shall be deemed
          to be a termination other than for Cause unless it meets all
          requirements of this Section 9.3.

          upon and shall inure to the benefit of the Company, its successors and

          indirect, by purchase, merger, consolidation or otherwise) or assign,
          by agreement in form and substance satisfactory to the Executive, to
          expressly assume and agree to perform this Agreement in the same
          manner and to the same extent that the Company would be required to
          perform it if no such succession or assignment had taken place.
          Failure of the Company to obtain such assumption and agreement prior
          to the effectiveness of any such succession or assignment shall be a
          breach of this Agreement and shall entitle the Executive to
          compensation from the Company in the same amount and on the same terms
          as he would be entitled to hereunder if his employment had been
          terminated pursuant to Section 11.2 hereof, except that for purposes
          of implementing the foregoing, the date on which any such succession
          or assignment becomes effective shall be deemed the Termination Date
          hereunder. As used in the Agreement, Company shall mean the Company as

          If the Executive should die while any amounts would still be payable
          to him hereunder if he had continued to live, all such amounts, unless
          otherwise provided herein, shall be paid in accordance with the terms
          of this Agreement to the Executive's devise, legatee or other designee
          or, if there be no such designee, to the Executive's estate.
