          this Agreement will not be so extended, in which case the term of this

                provisions of this Agreement as if they were fully set forth
                herein, and shall apply consistently to all employees, except as
                deviations from this requirement are necessitated by physical or

                                      2
   3
                 to the reimbursement, resulting in a "no gain/no loss" position
                 to Executive.

                 Notwithstanding the above, the Company's reimbursement to
                 Executive under this section shall not exceed $50,000.

6.        Termination and Resignation - The Company shall have the right to
          terminate the Executive's employment hereunder at any time and for any
          reason, and upon any such termination the Executive shall be
          entitled to receive from the Company prompt payment of the amount
          determined pursuant to the applicable subparagraph of Paragraph 7
          below.  The Executive shall have the right to terminate his employment
          hereunder at any time by resignation, and he shall thereupon be
          entitled to receive from the Company prompt payment of the amount
          determined pursuant to the applicable subparagraph of Paragraph 7
          below.

7.        Payments Upon Termination and Resignation

7.1       Pro Rata Payments - If (a) the Company at any time terminates the
          Executive's employment for cause (as defined below), or (b) prior to
          the occurrence of a Change In Control (as defined below) of the
          Company, the Executive voluntarily resigns for any reason other than
          because of an uncured material breach by the Company of any term of
          this Agreement, then in each case the Executive shall be entitled to
          receive only his Base Salary on a pro rata basis to the date of
          termination.  If the Executive at any time dies or becomes disabled
          (being the inability of the Executive to perform his normal employment
          duties for the remainder of the term of this Agreement because of
          either physical or mental incapacity), the Executive shall be entitled
          to receive only his Base Salary plus Average Bonus (as defined below)
          on a pro rata basis to the date of termination or resignation.  For
          purposes of this Paragraph 7.1, "pro rata" shall mean the product of
          the Executive's annual Base Salary and Average Bonus that would have
          been payable had the Executive's employment not terminated multiplied
          by a fraction the denominator of which is 365 and the numerator of
          which is the number of days during the calendar year that have passed
          through the date of the termination of the Executive's employment.

7.2       Base Salary and Average Bonus Payment - If prior to the occurrence of
          an Initial Change in Control Event (as defined below), the Company
          terminates the Executive's employment because of a Discharge Event (as
          defined below), or if prior to the occurrence of a Change in Control
          of the Company, the Executive resigns because of the uncured material
          breach by the Company of any term of this Agrement, then in each case
          the Executive shall be entitled to receive a lump sum payment equal to
          his Base Salary and Average Bonus.

7.3       Change of Control Payment - If after the occurrence of an Initial
          Change of Control Event of the Company, the Company terminates the
          Executive's employment hereunder (a) because of a Discharge Event, or
          (b) without Cause and without any Discharge Event, then in either case
          the Company will pay to the Executive a lump sum termination payment
          equal to his Base Salary and his Average Bonus (collectively, the
          "Lump Sum Payment").  If after the occurrence of a Change in Control
          of the Company, (a) the Company terminates the Executive's employment
          hereunder for any reason other than for Cause (other than his death or
          disability), or (b) the Executive voluntarily resigns his employment
          hereunder for any reason (other than his death or disability), then in
          each





                                       3

   4
          case the Company will pay to the Executive the Lump Sum Payment.

7.4       Contract Term Payment - If prior to the occurrence of an Initial
          Change in Control Event of the Company, the Company terminates the
          Executive's employment hereunder without Cause and without any
          Discharge Event, then the Executive shall be entitled to receive his
          Base Salary plus his Average Bonus, payable in the same amounts and at
          the same times as if the Executive's employment had not terminated,
          for 12 months from date of termination. If notice is given to the
          Executive by the Company pursuant to Section 2 of this Agreement that
          the term of this Agreement will not be extended, the Executive shall
          be entitled to receive his Base Salary plus his Average Bonus, payable
          in the same amounts and at the same times as if the Executive's
          employment had not terminated, for 12 months from the date of
          termination.

7.5       Certain Definitions

          (a)    "Average Bonus" shall mean that result obtained by dividing the
                 sum of the bonuses, if any, paid to the Executive pursuant to
                 Paragraph 5.1(a) above in respect of the two years next
                 preceding the year of Executive's termination or resignation by
                 the number of years during such two-year period in which the
                 Executive was entitled to receive a bonus pursuant to paragraph
                 5.1(a) above.

          (b)    Termination by the Company of the Executive's employment for
                 "Cause" shall mean termination upon the willful
                 misappropriation of funds or properties of the Company or the
                 willful contravention of the standards referred to in the last
                 sentence of Paragraph 10 below.  For purposes of this
                 definition, no act, or failure to act, on the Executive's part
                 shall be considered "willful" unless done, or omitted to be
                 done, by the Executive not in good faith and without reasonable
                 belief that the Executive's action or omission was in the best
                 interest of the Company.  Notwithstanding the foregoing, the
                 Executive shall not be deemed to have been terminated for Cause
                 unless and until there shall have been delivered to the
                 Executive a copy of a resolution duly adopted by the
                 affirmative vote of not less than three-quarters of the entire
                 membership of the Board of Directors of the Company at a
                 meeting of the Board duly called and held (after reasonable
                 notice to the Executive and an opportunity for the Executive,
                 together with his counsel, to be heard before the Board)
                 finding that in the good faith opinion of the Board the
                 Executive was guilty of the conduct set forth above and
                 specifying the particulars thereof in detail.

          (c)    A "Change in Control" shall be conclusively deemed to have
                 occurred if (and only if) any of the following shall have taken
                 place:  (i) a change in control is reported by the Company in
                 response to either Item 6(e) of Schedule 14A of Regulation 14A
                 promulgated under the Securities Exchange Act of 1934, as
                 amended ("Exchange Act"), or Item 1 of Form 8-K promulgated
                 under the Exchange Act; (ii) any person (as such term is used
                 in Section 13(d) and 14(d)(2) of the Exchange Act) is or
                 becomes the beneficial owner (as defined in Rule 13d-3 under
                 the Exchange Act) directly or indirectly, of securities of the
                 Company representing fifty-one percent or more of the combined
                 voting power of the Company's then outstanding securities; or
                 (iii) following the election or removal of directors, a
                 majority of the Board consists of individuals who were not
                 members of the Board two years before such election or removal,
                 unless the election of each director who was not a director at
                 the beginning of such two-year period has been approved in
                 advance by directors representing at least a majority of the
                 directors then in office who were directors at the beginning of
                 the two-year period.

          (d)   The "Code" shall refer to the Internal Revenue Code of 1986, as
                amended.
          
          (e)   A "Discharge Event" shall have occurred if the Executive shall
                have received a copy of a resolution duly adopted by
                the affirmative vote of a majority of the members of the
                Compensation Committee of the Board of Directors of the Company
                finding that, upon the recommendation of and for the reasons
                cited by the Chairman of the Company, the Executive is no
                longer discharging his duties in a manner consistent with the
                effective administration of the affairs of the Company and
                hence the continued employment of the Executive is no longer in
                the best interest of the Company.

          (f)   An "Initial Change in Control Event" shall be conclusively
                deemed to have occurred when any individual, group,
                partnership, corporation, trust or other entity ("Person")
                initiates a course of action or conduct that, in the good faith
                judgement of the Board of Directors of the Company, might
                reasonably be expected to lead to a Change in Control of the
                Company. For example and without limiting the scope of the
                foregoing, an Initial Change in Control Event would include the
                public announcement or other disclosure by a Person of its
                intention (i) to acquire by private or open market purchase,
                tender offer, exchange offer, or otherwise forty percent or
                more of the combined voting power of the Company's outstanding
                securities, or (ii) to solicit proxies or consents for the
                removal of at least three incumbent directors or the election
                of at least persons to serve as directors of the Company in
                opposition to nominees proposed by the Board of Directors of
                the Company.

8.        Acceleration of Options - Contemporaneously with the occurrence of a
          Change in Control of the Company, the Board of Directors of the
          Company (or the appropriate committee thereof) to the extent
          allowable under the plan, will accelerate all outstanding operations
          previously granted to the Executive under any then existing Company
          stock option, stock appreciation or other employee incentive plan that
          are not otherwise exercisable by the Executive at the time the Change
          in Control of the Company occurs.

9.        Title and Interests in Employee Inventions and Work Product - 
          Executive recognizes, acknowledges, and hereby agrees that all
          work products, hardware or software, produced, designed or improved
          while under the employ of ENVOY, whether patentable or not, become
          and shall remain the exclusive property of ENVOY and thereby ENVOY
          has the exclusive right to use, manufacture, license and/or sell all
          inventions, design work, products and any tangible or intangible work
          product produced, developed or improved while Executive is employed
          by ENVOY. It is herby mutually agreed that upon termination of this
          Agreement, for whatever reason, Executive shall have no ownership,
          interest, license or claim with respect to any work product or
          products covered hereunder or to the goodwill in any such work
          product.

10.       Confidentiality and Non-Disclosure of Information - Executive
          recognizes, acknowledges and hereby agrees that all information
          acquired by virtue of this Agreement or the relationship created by
          this Agreement concerning ENVOY customer names, contracts, number of
          retail establishments, dollar volumes of business, transaction
          volumes, establishment discounts, and other customer data obtained
          through confidentiality or service agreements constitute TRADE
          SECRETS of ENVOY and will be treated by Executive as confidential and
          proprietary and shall not be used or disclosed, in whole or in part,
          to any person, firm, corporation, association, or other entity for
          any reason or purpose whatsoever during the term of this Agreement.

          corporation, association, or other entity to whom such list, in whole
          or in part, has been disclosed.  Nothing herein shall be construed as
