acceleration and vesting of Executive's options has occurred.

                           (iii) In the event Executive is terminated without
cause the provisions of 7(d) shall apply.

                  In the event Executive is terminated for cause as set forth in
Section 7(c), or in the event Executive voluntarily terminates Executive's
employment for any reason other than an acquisition as set forth in Section
6(c)(ii), the Executive's right to vest in the stock options shall terminate at
the end of the vesting quarter in which the Executive was terminated, and no
further vesting shall occur.

accepting this appointment, the Company agrees to pay Executive promptly
following the commencement of Executive's employment $25,000 net of all Federal

                  (f) VACATION. Executive shall be entitled to four (4) weeks
vacation per year.

                  (g) EMPLOYEE BENEFITS. The Company shall provide at no cost to

employee savings or 401(k) plans.

                  (h) REGISTRATION RIGHTS. Executive shall have reasonable and
customary piggy back registration rights with respect to any shares granted to
Executive (including shares received upon exercise of stock options) if such
shares cannot otherwise be sold without registration.

         7. TERMINATION. Executive's employment may be terminated in any one of
the following ways, prior to the expiration of the Initial Term:

                  (a) DEATH. The death of Executive shall immediately terminate
this Agreement. Any rights or entitlements pursuant to this Agreement earned
prior to the death of Executive will inure to the benefit of Executive's estate.




                                       4
<PAGE>   5


All unvested options shall vest upon death and inure to the benefit of the
Executive's estate as defined in 6(c)(i.) above.

                  (b) DISABILITY. If, as a result of incapacity due to physical
or mental illness or injury, Executive shall have been unable to perform the
essential functions of Executive's position on a full-time basis for a period at
least six (6) months with a reasonable accommodation, then thirty (30) days
after written notice to the Executive (which notice may be given before or after
the end of the aforementioned period, but which shall not be effective earlier
than the last day of the applicable period), the Company may terminate
Executive's employment hereunder if Executive is unable to resume Executive's
full-time duties at the conclusion of such notice period. In the event of a
termination pursuant to this Section 7(b), all payments to Executive due
pursuant to this Agreement shall cease effective the last day of Executive's
employment, but all benefits (as defined in 6(f) shall continue for the greater
of one year following termination for disability and/or the terms of this
agreement. The appointment by the Company of an interim executive to assume the
responsibilities of the Executive while the Executive is incapacitated shall not
constitute a breach of Section 1 of this Agreement.

                  (c) TERMINATION BY THE EMPLOYER FOR CAUSE. The Company may
terminate Executive's employment for Cause immediately upon written notice.
Termination for cause is defined as: (i) Executive's material breach of this
Agreement or of any Proprietary Information Agreement (however denominated)
between the Company and the Executive; (ii) Executive's gross negligence in the
performance of Executive's duties hereunder, intentional failure to perform such
duties, or refusal to abide by or comply with the reasonable directives of the
Chairman, the Board, or the Company's policies and procedures; (iii) Executive's
dishonesty, fraud or misconduct with respect to the business or affairs of
Company or which in the reasonable judgment of the Company materially and
adversely affects the operation or reputation of Company; (iv) Executive's



                                       5
<PAGE>   6


conviction of a felony or a crime involving moral turpitude; or (v) Executive's
abuse of alcohol or drugs (legal or illegal) that in the Company's reasonable
judgment materially impairs Executive's ability to perform Executive's duties
hereunder.

         In the event Executive is terminated for cause pursuant to this Section
7(c), all payments and benefits, including the future vesting of stock options,
to Executive due pursuant to this Agreement, shall cease in accordance with
paragraph 6(c)(ii).

                  (d) TERMINATION BY COMPANY WITHOUT CAUSE. The Company may
terminate Executive's employment without Cause immediately upon written notice
to Executive. If terminated within the first year of employment, the Company
shall pay Executive severance in a lump sum amount equal to Executive's then
base annual salary plus full annual bonus as specified in 6(b) above, and all
remaining unvested stock options shall vest immediately. Otherwise if Executive
is terminated without cause anytime after one (1) year, Executive is entitled to
one month severance of Executive's then annual salary and all remaining unvested
stock options shall vest immediately, provided Executive executes a full release
of all claims against the Company. Such severance pay shall not be subject to
reduction for any reason. The employee by accepting severance pay agrees to a
strict non-solicitation of EDV employees and/or customers.

                  (e) EXECUTIVE'S RESIGNATION. Executive may voluntarily
terminate Executive's employment upon not less than thirty (30) days' prior
written notice. Upon any such resignation, except to the extent such resignation
occurs in the context of an acquisition as defined by Section 6(c)(ii), all
payments and benefits due pursuant to this Agreement for future services shall
cease effective the last day of Executive's employment and all earned amounts
shall be paid in full. In the event Executive voluntarily terminates within one



                                       6
<PAGE>   7


year from the date of an acquisition as defined in 6(c)(ii) above, Executive
shall still be entitled to the same benefits as those defined in paragraph 7(d)
(Termination Without Cause).

         8.       CONFIDENTIALITY.

                  (a) Executive understands that during the course of
Executive's employment with the Company he will receive and have access to

wrongful act of Executive.

                  (b) FORMER EMPLOYER INFORMATION. Executive agrees that he will

person or entity and that he will not bring onto the premises of the Company any
unpublished document or proprietary information belonging to any such employer,
person or entity unless consented to in writing by such employer, person or
entity.

                  (c) THIRD PARTY INFORMATION. Executive recognizes that the
Company has received and in the future will receive from third parties their
confidential or proprietary information subject to a duty on the Company's part
to maintain the confidentiality of such information and to use it only for




                                       7

certain limited purposes. The Executive agrees to hold all such confidential and
proprietary information in the strictest confidence and not to disclose it to
any person, or entity or to use it except as necessary in carrying out
Executive's work for the Company consistent with the Company's agreement with
such third party.

                  (d) SURVIVAL. The provisions of this Section 8 shall survive
the termination of the remainder of this Agreement.

         9. EFFECT OF TERMINATION. Executive agrees that upon termination of
Executive's employment, he will deliver to the Company (and will not keep in
Executive's possession, recreate or deliver to anyone else) any and all devices,
records, data, notes, reports, proposals, lists, correspondence, specifications,
materials, equipment and other documents or property or reproductions of any of
the aforementioned items developed or received by Executive pursuant to
Executive's employment with the Company or otherwise belonging to the Company,

Executive personal files relating to Executive's service as a director of the
Company.

prior agreements, proposals, representations and commitments, oral and
otherwise. This Agreement may only be amended by an instrument signed by an
