                              PINNACLE MICRO, INC.
                              EMPLOYMENT AGREEMENT


       This employment agreement (the "Agreement") is made and entered into by
and between Roger Hay ("Executive") and Pinnacle Micro, Inc., (the "Company"),
effective as of December 1, 1996 (the "Effective Date") with reference to the
following facts:

       Executive has been recruited by Company to fill a critical executive
position. The Company is going through a management transition and financial
turnaround. Company and Executive desire to agree upon the services to be
rendered for such period of time upon the terms and conditions set forth herein.
The Company's Board further believes that it must provide the Executive with
certain enhanced severance benefits upon Executive's termination of employment
following a change of control (as defined below) to provide the Executive,
through enhanced financial security, incentive to continue providing services to
the Company notwithstanding the possibility of a change of control.

       NOW, THEREFORE, in consideration of the premises and of the mutual
convenants and conditions set forth herein, the parties hereto agree as follows:

       1.       Employment; Duties: (a) Employment Period: During the period
commencing with the Effective Date and terminating 2 years for (the "Contract
Employment Period") or on the date (the "Termination Date") that Executive is
terminated in accordance with Sections 5, 6 or 7 of this Agreement or resigns
for whatever reason, (the "Employment Period"), Executive shall serve as
Executive Vice President, Chief Financial Officer of the Company or in such
other position as he accepts prior to a Change of Control. During such
employment period, Executive shall discharge the duties of his office as shall
reasonably be assigned to him by the President and Chief Executive Officer. The
Contract Employment period shall be automatically annually extended for 12 month
periods after the expiration of the initial term unless otherwise terminated in
accordance with this Agreement.

                (b) No Conflict of Interest: During the Employment Period,
Executive shall not serve as a director, employee, consultant or advisor to any
other corporation or other business enterprise without the prior written consent
of the Board; which consent shall not be unreasonably withheld. Executive may,
however, serve in any capacity with any civic, educational or charitable
organization or any trade association without the approval of the Board, so long
as such activities do not interfere with his duties and obligations under this
Agreement. If the Board views any such activities as interfering it shall notify
Executive and provide a reasonable opportunity to cure the interference.

       2.       Compensation:

                (a) Base Salary: During the Employment Period, the Company shall
pay Executive a base salary (the "Employment Base Salary") at a rate of not less
than $225,000.00 per year, payable in equal installments no less frequently than
twice monthly.

                (b) Bonuses: During the Employment Period, Executive shall
receive bonuses (i) as determined by the Compensation Committee of the Board of
Directors in consultation with the President and Chief Executive Officer; and
(ii) according to the terms of any Company executive bonus plans.

                (c) Stock Options: During the Employment Period Executive will
receive such stock options or similar performance incentives as determined
separately in writing by the Compensation Committee of the Board of Directors in
its sole discretion after consultation with the President and Chief Executive
Officer. A summary of Executive's initial grant is attached hereto as Exhibit A.

       3.       Employee Benefits: During the Employment Period, Executive 
shall be included in all employee benefit plans, programs or arrangements, 
including, without limitation, any plans, programs or arrangements providing 
for retirement benefits, incentive compensation, profit bonuses, disability 
benefits, health and life

for, or made available to, its senior executives and to such other benefits and

of any of the following events:

                      (i)    Any "person" or group (as such terms and used in

percent (50%) of the total voting power represented by the voting securities of
the surviving entity outstanding immediately after such merger or consolidation;
or

                      (iv)   The stockholders of the Company approve a plan of 
complete liquidation of the Company or an agreement for the sale or disposition
by the Company of all or substantially all the Company's assets.

                (c) Disability: "Disability" shall mean that the Executive has
been unable to perform his Company duties as the result of his incapacity due to
physical or mental illness, and such inability, at least 26 weeks after its
commencement, a determined by the Company (or by a physician agreed upon by the
parties or selected by the Arbitrator if the parties cannot agree) to be total

an Arbitration an Disability shall be deemed to exist. Termination resulting
from Disability may only be effected after at least 30 days' written notice by
the Company of its intention to terminate the Executive's employment. In the
event that the Executive resumes the performance of substantially all of his
duties hereunder before the termination of his employment becomes effective, the
notice of intent to terminate shall automatically be deemed to have been
revoked.

                (d) Other Benefits: Pay to Executive, his estate, or his
personal representative (as appropriate) all other benefits normally paid to
employees who have died or incurred a disability.

       8. Golden Parachute Limitation: The payments and benefits payable to
Executive under this Agreement and all other contracts, arrangements, or
programs with the Company shall not, in the aggregate exceed the maximum amount
that may be paid to Executive without triggering golden parachute penalties
under Section 280G of the Internal Revenue Code of 1986, as amended (the
"Code"), as determined in good faith by the Company's independent auditors.
Executive agrees that, to the extent payments or benefits under this Agreement
would not be deductible under Code Section 162(m) if made or provided when
otherwise due under this Agreement, such payments and benefits shall be made or
provided later, immediately after Section 162(m) ceases to preclude their
deduction, with interest thereon at the rate provided in Code Section
1274(b)(2)(B). If even after such deferral the payments and benefits otherwise
payable to Executive must be reduced to avoid triggering such penalties, the
payments and benefits will be reduced in the priority order designated by the
Executive, or, if the Executive fails promptly to designate an order, in the
priority order designated by the Company. If an amount in excess of the limit
set forth in this Section 8 is paid to Executive, Executive shall repay the
excess amount to the Company upon demand. Executive and the Company agree to
cooperate with each other in connection with any administrative or judicial
proceedings concerning the existence or amount of golden parachute penalties on
payments or benefits received by Executive.

       9. Termination Date: The date of termination of employment by the Company
shall be the date specified in a written notice of termination to Executive. The
date of resignation shall be the date specified in the written notice of
resignation from Executive to the Company. For purposes of this Agreement, no
purported termination of Executive's employment for Cause shall be effective
without delivery of such Notice of Termination.

       10. Assignment: Executive's rights and obligations under this Agreement
are not assignable by Executive, but shall pass to his estate or personal
representative upon death or disability (as determined pursuant to this
Agreement).

be given in writing and shall be deemed to have been effectively made or given

such party may designate by written notice to the other party hereto. Any

is expressly waived, with the sole exception of a Company initiated injunctive
proceeding to protect its confidential information or trade secrets, judgment
upon such decision may be entered in any court having jurisdiction thereof. The
parties hereby agree that the Arbitrator shall be empowered to enter an
equitable decree mandating specific enforcement of the terms of this Agreement.

of the legal fees and out-of-pocket expenses of
