hereby agrees to serve the Company as its President and Chief Executive Officer
for the period hereinafter defined. Executive agrees to perform such services as
shall from time to time be assigned to him by the Company's Board of Directors

during the Company's normal working hours and his best efforts and ability to
the affairs of the Company and any such subsidiaries and shall not engage in
other activities that interfere with the proper discharge of his duties or that
compete with the interests of the Company, provided that Executive may devote
reasonable time to serving as a director or member of charitable, religious or
business organizations so long as the same do not result in a conflict of
interest with the interests of the Company. During the term of this Agreement,
Executive shall conform to all the Company's policies and procedures and pledges
to maintain all business activities of the Company in complete confidence and
keep the Company informed, apprised and aware of all material matters that come
to his attention that could affect its business interest.

Company shall initially pay Executive an annual salary of Three Hundred Thousand
($300,000) Dollars payable in appropriate installments to conform with regular
payroll dates for salaried personnel of the Company. Such salary may be
increased (but not decreased) by the Board of Directors at any time.

         3. EXPENSE. It is contemplated that, in connection with his employment
hereunder Executive may be required to incur reasonable business entertainment
and travel expenses. The Company agrees to reimburse Executive in full for all
reasonable and necessary business entertainment and other related expenses
including, without limitation, travel expenses, incurred or expended by him
incident to the performance of his duties hereunder upon submission by Executive
to the Company of vouchers or expense statements reasonably evidencing such
expenses.

         4. FRINGE BENEFITS. During the period of his employment with the
Company hereunder, Executive shall be entitled to participate in any and all
group health insurance, life insurance, accident insurance, medical, pension,
profit sharing or other employee benefit plans 
<PAGE>   2

made available by the Company to all the employees of the Company. The Company
retains the right to increase or reduce such benefits, from time to time, as it
deems to be appropriate. 

         5. VACATIONS. It is understood and agreed by the parties that Executive
shall be entitled to vacations (taken consecutively or in segments) in a
accordance with the normal policy of the Company in effect from time to time.

         6. TERM AND TERMINATION.

         (a) Unless earlier terminated as provided herein, this Agreement shall
continue in effect for a period of three (3) years from the date hereof and from
month to month thereafter unless either party provides the other with at least
thirty (30) days written notice of its intention not to renew this Agreement.

         (b) The Board of Directors of the Company may terminate the employment
of Executive at any time in the event Executive: (i) is convicted of a felony or
misdemeanor involving moral turpitude; (ii) shall have materially breached any
provision of this Agreement within his control or failed to properly and
diligently perform his duties hereunder and shall not have remedied such
violation within twenty (20) days after notice from the Board of Directors or
the Chairman of the Company specifying such violation; or (iii) commits any act
or acts that constitute a breach of Executive's fiduciary duties or duties of
good faith and loyalty. In any termination under this Subsection 6 (b) (a "Cause
Termination") all rights to future compensation hereunder shall terminate as of
the date of termination.

         (c) The Board of Directors of the Company may also terminate the
employment of Executive in the event Executive (i) dies or (ii) shall become
physically or mentally incapacitated or disabled or otherwise unable fully to
discharge his duties hereunder as determined by a physician licensed in the
State of Michigan selected by the Board of Directors. In the event of a
termination pursuant to this Subsection 6 (c), Executive or his estate shall
receive payments in accordance with Section 7.

         (d) The Board of Directors of the Company may also terminate
Executive's services for reasons other than a Cause Termination, in which case
Executive shall receive severance pay determined in accordance with Section 6
(f).

         (e) Executive may terminate his employment under this Agreement if the
Company shall have violated any material provision of this Agreement and shall
not have remedied such violation within twenty (20) days after notice from

determined as if that termination has not occurred. The parties agree that the
payments to be made pursuant to this Subsection 6 (f) shall be Executive's sole
and exclusive 
<PAGE>   3
remedy hereunder and Executive hereby waives any claims for any further
compensation, benefits or damages of any nature or description under this
Agreement. The parties agree that, because there can be no exact measure of the
damage that would occur to Executive as a result of a breach, and the Company
agrees that Executive receive compensation for services rendered or consulting
fees during the Severance Pay Period, the amount of that compensation or those
consulting fees shall reduce, but not below zero, the amount payable by the
Company to Executive pursuant to this Agreement.

         7. PAYMENTS ON DEATH OR DISABILITY

         (a) In the event of the termination of this Agreement as the result
Executive's death, remuneration pursuant to Section 2 for the month in which his
death occurs shall be paid to Executive's beneficiary designated in writing
filed by him with the Company or, if none, to his estate. Upon that payment, the
Company thereafter shall be discharged and released of and from any further
obligations under this Agreement except for its obligations to pay any accrued
bonuses or deferred compensation.

         (b) In the event of the termination of this Agreement pursuant to
Section 6 (c) as the result of Executive's disability, Executive shall be
entitled to receive the full compensation specified in Section 2 hereof for a
period of ninety (90) days after the initial date of his disability and fifty
percent of that compensation for the next ninety (90) day period thereafter and
the Company shall thereafter be discharged and released of and from any further
obligations under this Agreement except for it obligations to pay any accrued
bonuses or deferred compensation. Notwithstanding anything contained in this
Agreement to the contrary, in the event Executive is receiving payments through
a disability policy maintained by the Company, such payments will not be
deducted from any amounts payable by the Company to Executive hereunder during
the period such disability payments have been made.

         8.  INDEMNIFICATION Executive shall be entitled to be indemnified for
any loss suffered by him by reason of his acting as an officer, employee or

merchandise, products, leasing and financing services, training services, help
desk services, systems integration services and other services of the Company or
its successors or assigns (or any good, products or services similar thereto),
sold, distributed, or rendered by the Company or its subsidiaries or affiliates
at the time the Executive's employment ceased or during any period two (2) years
prior thereto.

         (f) As used in this Section 9, the term "Customer" shall mean all
persons, firms or corporations for whom the Company or its subsidiaries or
affiliates performed Services or to whom the Company or its subsidiaries or
affiliates sold its Services at the time the Executive's employment ceased or
during any period six (6) months prior thereto, notwithstanding the fact that
some or all of such persons, firms or corporations may have been induced to give
their patronage or business to the Company or its subsidiaries or affiliates by
the solicitation of the Executive or due to Executive or due to Executive's
employment by the Company.

         (g) If any of the restrictions set forth above should, for any reason
whatsoever, be declared invalid by a court of competent jurisdiction, the
validity or enforceability of the remainder of such restrictions shall not
thereby be adversely affected.

         (h) The Executive recognizes that the foregoing territorial and time
limitations are reasonable and properly for the adequate protection of the
business of the Company, and that in the event that any such territorial or time
limitation is found to be unreasonable by a court of competent jurisdiction,
then the Executive agrees and submits to the reduction of either said
territorial or time limitation to such an area or period as the court shall find
reasonable.
<PAGE>   5
         (i) In the event that the Executive shall be in violation of the
aforementioned restrictive covenants, then the time limitation thereof in
respect of the Executive shall be extended for a period of time equal to the
period of time during which such breach or breaches should occur, and, in the
event the Company should be required to seek relief from such breach in any
court, board of arbitration or other tribunal, then the covenant shall be
extended for a period of time equal to the pendency or such proceedings,
including all appeals.

         (j) Both parties hereto recognize that the services to be rendered
under this Agreement by Executive are special, unique and of extraordinary
character, and that in the event Executive performs services for any person,
firm or corporation engaged in a competing line of business with the Company in
violation of the covenants of this Section 9 hereof, then the Company shall be
entitled, if it so elects, to institute and prosecute proceedings in any court
or competent jurisdiction, either in law or in equity, to obtain damages for
breach of this Agreement, or to enjoin Executive from performing services for
any such other person, firm or corporation.

         10.  NON-DISCLOSURE OF CONFIDENTIAL INFORMATION.

         (a) Executive understands and hereby acknowledges that, as a result of
his employment with the Company, he will necessarily become informed of, and
have access to confidential information of the Company including, without
limitation, its computer programs and software, inventions, discoveries,
processes, trade secrets, technical information, know-how, plans,
specifications, identity of customer and identity of supplier, and that such
information, even though it may be developed or otherwise acquired by Executive,
is the exclusive property of the Company to be held by Executive in trust and
solely for the Company's benefit. Accordingly, Executive hereby agrees that he
shall not, at any time, either during or subsequent to his employment hereunder,
use, copy, reveal, report, publish, transfer or otherwise disclose to any
person, corporation or other entity, any of the Company's confidential
information without the prior written consent of the Company, except for use on
behalf of the Company in connection with the Company's business. Notwithstanding
the foregoing, the provisions of this Section shall not apply to any information

disclosure by Executive; (ii) was available on a nonconfidential basis prior to
its disclosure to Executive by the Company or its representatives, or (iii)
becomes available to Executive on a nonconfidential basis from a source other
than the Company or its representatives provided that such source is not bound
by a confidentiality agreement with the Company or its representatives. For the
purposes of this Section, the term "the Company" shall also mean and include its
parents, subsidiaries, joint ventures and other affiliates. The obligations of
this Section shall also apply to proprietary or confidential information of
another party which the Company receives in the normal course of Executive's
employment with the Company. 

         (b) Because the Company does not have an adequate remedy at law to
protect its interests in its trade secrets, privileged, proprietary or
confidential information and similar commercial assets, the Company shall be
entitled to injunctive relief, in addition to such other remedies and relief
that would, in the event of a breach of the provisions of this Agreement, be
available to the Company. In the event of such a breach, in addition to any
other remedies, the Company shall be 

<PAGE>   6
entitled to receive from Executive payment of, or reimbursement for, its
reasonable attorney's fees and disbursements incurred in enforcing any such
provision.

         11. COPYRIGHTS, INVENTIONS, ETC. Any interest in patents, patent
applications, inventions, copyrights, developments, and processes that Executive
may develop during the term hereof relating to the fields in which the Company
may then be engaged (the "Covered Developments") shall belong to the Company;
and forthwith upon request of the Company, Executive shall execute all such
assignments and other documents and take all such other action as the Company
may reasonably request in order to vest in the Company all his right, title, and
interest in and to the Covered Developments free and clear of all liens,
charges, and encumbrances.

         12. COMPANY PROPERTY. Executive acknowledges that all Company manuals,
hand-books, benefits information and other property provided for the use of
Executive are the property of the Company. Upon termination or whenever
requested, Executive shall immediately return any and all Company property which
is in the Executive's possession or control.

         13. PRIOR COMMITMENTS. Executive hereby warrants and represents that he
is free to enter into the Company's employ and that there are no employment
contracts or restrictive covenants preventing full performance of Executive's
duties hereunder. Executive agrees that he will not disclose to the Company or
induce the company to use any trade secrets or other proprietary or confidential
information that my have been gained by Executive during any prior employment
which he is under a written obligation not to disclose.

         14. CONFLICT OF INTEREST.

             owner, officer, director, participant, licensee, consultant,
             shareholder or as the recipient of wages, commissions, or other
             compensation of value) that sells or provides materials, equipment,
             or facilities to the Company, or that is a customer of the Company.
             (Shares of stock in publicly held companies acquired by Executive

             new, used, obsolete, or scrap) sold by the Company or in any used
             property (e.g., equipment, facilities and furniture) of the
             company.

         (b) Executive agrees that during his employment with the Company he
will report immediately any gifts, entertainment, or any other personal favors
or preferment's given to or received from anyone with whom the Company has or is
likely to have any business dealings, including an employee, prospective
employee, customer, competitor, or vendor, which go beyond common courtesies
usually associated with accepted business practice.

         (c) Executive further agrees to report immediately any circumstances or
situations arising in the future that might involve him or appear to involve him
in a conflict of interest.

         15. BINDING EFFECT. Executive's rights and obligations under this
