jointly with others) that are related to in any fashion or manner to the
businesses, products or technologies of Trimark.

     2.   NON-COMPETITION.

          2.1  NON-COMPETE AGREEMENT.  Shareholder agrees that he will not at
any time within the two (2) year period immediately following the date of this
Agreement, directly or indirectly engage in, or have any interest in any
Conflicting Organization or any other entity (whether as an employee, officer,
director, agent, security holder, partner, creditor, consultant, licensor,
licensee, or otherwise) that engages in, or is preparing to engage in, any
activity in any county or city in the United States of America in which Trimark,
has carried on business, which activity is the same as, similar to, or
competitive with any business now carried on by Trimark or which manufactures,
distributes, licenses or markets a Conflicting Product, in any of such counties
or cities, as long as NHancement or Trimark (or any successor or successors
thereto) shall carry on such business in such county or city.

          2.2  CONSTRUCTION.  The parties intend that the covenant contained in
Section 2.1 shall be construed as a series of separate covenants, one for each
county and city.  Except for geographic coverage, each such separate covenant

<PAGE>

NHancement / Trimark /
                      --------------
Non-Compete and Technology Transfer Agreement
Page 3

the preceding paragraph. If, in any judicial proceeding, a court shall refuse
to enforce any of the separate covenants included in this paragraph, then the
unenforceable covenant shall be deemed eliminated (or modified as set forth
below) from these provisions for the purpose of those proceedings to the extent
necessary to permit the remaining separate covenants to be enforced. If a court
determines that any covenant is unenforceable because it is unconscionable or
for any other reason, then the court may modify such covenant to make it
enforceable.

          2.3  INJUNCTIVE RELIEF.  The remedy at law for breach of this
non-compete covenant being inadequate, Shareholder understands, acknowledges and
agrees that NHancement shall be entitled, in addition to such other remedies it
may have, to temporary and permanent injunctive relief for any breach or
threatened breach of this non-compete covenant without proof of any actual
damages that have been or may be caused to it by such breach.

     3.   ASSIGNMENT OF INNOVATIONS.  Shareholder hereby assigns and agrees to
assign his or her full right, title and interest to the Innovations to Trimark.
In connection therewith, Shareholder shall, at the time of execution of this
Agreement, furnish to NHancement a written description of all Innovations known
to Shareholder and not previously furnished to NHancement, as well as all
written documents related thereto, and a written description of all other
Confidential Information or know-how related thereto.  If in the future
Shareholder becomes aware of an Innovation he has not previously reported to
NHancement, Shareholder will promptly report such Innovation to NHancement in
the manner set forth herein.  Shareholder agrees, at no charge to NHancement,
but at NHancement's expense: (a) to sign and deliver to NHancement such other
documents as NHancement considers desirable to evidence the assignment of all
rights of Shareholder, if any, to the Innovations to Trimark and Trimark's
ownership of such Innovations and (b) to cooperate with Trimark in performing
any lawful act or signing any document which NHancement in its sole judgment
considers necessary to apply for, prosecute, obtain or enforce any patent,
copyright, or other right or protection relating to any Innovation.  In the
event NHancement is unable to secure Shareholder's signature on any such
document, whether due to mental or physical incapacity or any other case,
Shareholder hereby irrevocably designates and appoints each of NHancement and
its duly authorized agents as his or her agent and attorney-in-fact, to act for
and in his or her behalf and stead, for the limited purpose of executing and
filing any such document and doing all other lawfully permitted acts to further
the prosecution, issuance and enforcement of patents, copyrights, or other
protections with the same force and effect as if executed and delivered by the
Shareholder.  This power of attorney shall not be affected by subsequent
incapacity of the principal.

     WARNING:  California Civil Code Section 2400 requires that Shareholder be
given the following warning:

     WARNING TO PERSON EXECUTING THIS DOCUMENT.
