    ------------------------

     (a)  Non-disclosure of Confidential Information and Trade Secrets.
          ------------------------------------------------------------
Consultant covenants and agrees that during the Consulting Period and
thereafter, except as may be required in performance of Consultant's services to
the Company, Consultant shall not disclose any Confidential Information. This
covenant is not intended to, and does not limit in any way Consultant's duties
and obligations to the Company under statutory and common law not to disclose or
make personal use of the Company's Confidential Information or trade secrets.

     (b)  Non-Interference with Customer Accounts. Consultant covenants and
          ---------------------------------------
agrees that during the Consulting Period and for a period of two (2) years
thereafter, Consultant shall not directly or indirectly, personally or on behalf
of any other person, business, corporation, or entity, contact or do business
with any customer of the Company with respect to any product, business or
activity which is competitive with any product business or activity of the
Company (a "Competitive Activity"). With regard to the Consultant's post-
Consulting Period obligations, this covenant applies to those customers and the
related entities of the customers to which the Company sold its products, parts
or services during the twelve-month period prior to the termination of the
Consulting Period, and those prospective customers with which the Company
actively pursued sales during the twelve-month period prior to such termination

     (c)  Non-Competition. Subject to such matters and activities as may be
          ---------------
approved by the Board of Directors of the Company in writing, Consultant
covenants and agrees that during

                                       4
<PAGE>

the Consulting Period and for a period of two (2) years thereafter, Consultant
shall not directly or indirectly own an interest in, operate, join, control,
advise, consult to, work for, serve as a director of, have a financial interest,
or participate in any corporation, partnership, proprietorship, firm,
association, person, or other entity that engages (or engaged) in any
Competitive Activity at the time of termination of the Consulting Period and/or
during the six month period prior thereto. This Covenant (as defined below)
applies in any country, territory or jurisdiction in which the Company is doing
business or making an active effort to do business at the time that this
Agreement is terminated. This Covenant does not prohibit the mere passive
ownership of less than one percent (1%) of the outstanding stock of any publicly
traded corporation as long as Consultant is not otherwise in violation of this
Covenant.

     (d)  No Diversion.  Consultant shall not divert or attempt to divert or
          ------------
take advantage of or attempt to take advantage of any actual or potential
business or opportunities of the Company or its subsidiaries, affiliates,
distributors or representatives, which Consultant became aware of as the result
of his engagement by the Company.

     (e)  Non-Recruitment.  Consultant agrees that the Company has invested
          ---------------
substantial time and effort in assembling its present workforce. Accordingly,
Consultant covenants and agrees that during his employment and for a period of
two (2) years following the termination of his employment, Consultant shall not
hire away, nor directly or indirectly entice or solicit or seek to induce or
influence any of the Company's employees to leave their employment.

     (f)  Remedies.  Consultant acknowledges that should he violate any of the
          --------
covenants contained in paragraphs 7, 8, 9(a), (b), (c), (d) and (e) above
(collectively "Covenants"), it will be difficult to determine the resulting
damages to the Company and, in addition to any other remedies it may have, the
Company shall be entitled to temporary injunctive relief without being required
to post a bond and permanent injunctive relief without the necessity of proving
actual damage. The Company may elect to seek one or more of these remedies at
its sole discretion on a case by case basis. Failure to seek any or all remedies
in one case does not restrict the Company from seeking any remedies in another
situation. Such action by the Company shall not constitute a waiver of any of
its rights.

     (g)  Severability and Modification of Any Unenforceable Covenant. It is the
          -----------------------------------------------------------
parties' intent that each of the Covenants be read and interpreted with every
reasonable inference given to its enforceability. However, it is also the
parties' intent that if any term, provision or condition of the Covenants is
held by a court of competent jurisdiction to be invalid, void or unenforceable,
the remainder of the provisions thereof shall remain in full force and effect
and shall in no way be affected, impaired or invalidated. Finally, it is also
the parties' intent that if a court should determine any of the Covenants are
unenforceable because of over breadth, then the court shall modify said covenant
so as to make it reasonable and enforceable under the prevailing circumstances.

     (h)  Tolling.  In the event of the breach by Consultant of any Covenant the
          -------
running of the period of restriction shall be automatically tolled and suspended
for the amount of time that the breach continues, and shall automatically
recommence when the breach is remedied so that the Company shall receive the
benefit of Consultant's compliance with the Covenants.

                                       5
<PAGE>

     (i)  No Other Defenses. Consultant agrees that the Covenants shall be
enforced independently of any other obligations between the parties, and that
the existence of any other claim or defense shall not affect the enforceability
of the Covenants or the remedies provided herein. This Agreement shall be in
addition to and shall not replace any other restrictive covenant Agreement that
Consultant may currently have with the Company or any related entity or may
hereinafter enter into with the Company or any related entity.

     (j)  No Assignment.  This Agreement and the rights and duties hereunder are
          -------------
personal to the Consultant and shall not be assigned, delegated, transferred,
pledged or sold by the Consultant without the prior written consent of the
Company. The Consultant hereby acknowledges and agrees that the Company may
assign, delegate, transfer, pledge or sell this Agreement and the rights and
duties hereunder (a) to an affiliate of the Company or (b) to any third party in
connection with (i) the sale of all or substantially all of the assets of the
Company or (ii) a merger or consolidation involving the Company. This Agreement
shall inure to the benefit of and be enforceable by the parties hereto, and
their respective heirs, personal representatives, successors and assigns.

     (k)  Survival.  This Section 9 shall survive the termination of this
          --------
Agreement.

10.  Indemnification
     ---------------

     (a)  Trade Secrets and Other Protected Information.  Consultant hereby
          ---------------------------------------------
indemnifies and shall hold harmless (including reasonable attorneys' fees) the
Company (hereinafter referred to as "Indemnified Party") against all liability
to third parties (other than liability solely the fault of the Indemnified
Party) arising from or in connection with the violation of any third party's
trade secrets, information, trademarks, copyright or patent rights in connection
with the performance of the consulting services under this Agreement.

     (b)  Personal Injury and Property Damage Indemnification.  Each party shall
          ---------------------------------------------------
defend, indemnify, and hold the other (Indemnified Party) harmless from and
against any and all claims, losses, damages, judgments, costs, and expenses
(including attorney's fees) which the Indemnified Party may suffer or incur
arising out of or in connection with injuries to persons (including death) or
loss of, or damage to, property, occasioned by negligence, unlawful act, or
willful misconduct of the Indemnifying Party provided the other party promptly
notifies the Indemnifying Party in writing of the claim and permits the
Indemnifying Party to control the direction of the litigation and selection of
counsel. The Indemnifying Party also reserves the right to control any
settlement.

     (c)  Duration of Indemnification. Obligations to indemnify any Indemnified
          ---------------------------
Party will survive the expiration or termination of this Agreement by either
party for any reason. Either party may, as its option, conduct the defense in
any third party action arising as described herein and the Indemnified Party
agrees to cooperate with such defense to the fullest extent possible.
