from and after the Closing Date, observe the following separate and independent
covenants:

            (a) Agreement Not to Compete. Shareholder shall not within the Area,
directly or indirectly, on his own behalf or in the service or on behalf of



                                        4





others, become financially interested in a Competing Business (other than as a

entity whose voting securities are listed on a national securities exchange or
quoted by the National Association of Securities Dealers, Inc. Automated
Quotation System), or render any services to any Competing Business as an
employee, consultant, partner, officer, director or in any other relationship
whatsoever.

            (b) Agreement Not to Solicit Customers. Shareholder shall not,
either directly or indirectly, on his own behalf or in the service or on behalf
of others, solicit, divert, or appropriate, or attempt to solicit, divert, or
appropriate, to any Competing Business, any person or entity whose account with

while he was associated with Virtual Reality at any time prior to the Closing
Date.

            (c) Agreement Not to Solicit Employees. Shareholder shall not,
either directly or indirectly, on his own behalf or in the service or on behalf
of others, solicit, divert or hire away, or attempt to solicit, divert, or hire
away, to any Competing Business, any person employed by Virtual Reality, the
Company or Sub, whether or not such employee is a full-time employee or a
temporary employee of the Company, Sub or Virtual Reality and whether or not
such employment is pursuant to written agreement and whether or not such
employment is for a determined period or is at will.

            (d) Ownership and Non-Disclosure and Non-Use of Confidential
Information. Shareholder acknowledges and agrees that all Confidential



                                        5





Information, and all physical embodiments thereof, are confidential to and shall
be and remain the sole and exclusive property of the Company. Shareholder agrees
that he will not: (i) disclose or make available any Confidential Information to
any person or entity, or (ii) make or cause to be made, or permit, either on his
own behalf or in the service or on behalf of others, any use of such
Confidential Information.

         3. Shareholder acknowledges that Virtual Reality has been for many
years, and that the Company and/or Sub are now, engaged in the Business
throughout the Area; that as a stockholder, director or officer of Virtual
Reality, he acquired unique knowledge of the customers, Business, and operations
of the Virtual Reality; that the within and foregoing covenants are made by him
in consequence of and as an inducement to the Company to acquire the Stock and
to protect and preserve to the Company the benefit of its bargain in the
acquisition of the Stock; that each of the above and foregoing covenants is
reasonable and necessary to protect and preserve the benefits of such purchase;
and that irreparable loss and injury would result should Shareholder breach any
of the foregoing covenants.

         4. Each of the covenants hereinabove contained shall be deemed
separate, severable, and independent covenants, and in the event any covenant
shall be declared invalid by any court of competent jurisdiction, such
invalidity shall not in any manner affect or impair the validity or
enforceability of any other part or provision of such covenant or of any other
covenant contained herein.

         5. If any of the covenants contained in Section 2, or any part thereof,
is held to be unenforceable because of the duration of such provision or the



                                        6





scope of the subject matter thereof or the area covered thereby, the parties
agree that the court making such determination shall have the power to reduce
the duration, scope and/or area of such provision and, in its reduced form, said
provision shall then be enforceable.

         6. In addition to all other remedies provided at law or in equity, the
Company shall be entitled to both preliminary and permanent injunctions against
Shareholder to prevent a breach or contemplated or threatened breach by
Shareholder of any of the foregoing covenants, without the necessity of proving
actual damages; and the existence of any claim, demand, cause of action, or
action of Shareholder against the Company and/or Sub, whether predicated upon
this Agreement or otherwise, shall not constitute a defense to the enforcement
by the Company of any such covenants. In the event of an actual breach of any of
the foregoing covenants, the Company shall have the right to recover damages for
all losses, actual and contingent, and the right to require Shareholder to
account for and pay over to the Company all profits or other benefits
(collectively "Benefits") derived or received by Shareholder as a result of any
transactions constituting such breach, and Shareholder hereby agrees to account
for and pay over such Benefits to the Company. Each of the rights and remedies
enumerated above shall be independent of the other, and shall be severally
enforceable, and all of such rights and remedies shall be in addition to, and
not in lieu of, any other rights and remedies available to the Company at law or
equity.

         7. The provisions of Sections 2 through 5 hereof shall be deemed to
supplement the provisions of the Employment Agreement of even date between the
Company and Shareholder ("Employment Agreement"). In the event of inconsistency



                                        7




between the terms of this Agreement and the Employment Agreement, this Agreement
and the Employment Agreement shall be construed together so as to provide the
broadest possible protection to the Company.

         8. This Agreement shall be governed by and construed in accordance with
the laws of the State of California.

         9. This Agreement may be executed and delivered in any number of
counterparts, each of which, when executed and delivered, shall be an original,
but all of which shall together constitute one and the same agreement.

         IN WITNESS WHEREOF, the undersigned have caused this Agreement to be
duly executed as of the date first above written.
