such injunction. If Company institutes any such action against Executive, alone
or in conjunction with any third party or parties to enforce any terms or
provisions of Paragraphs 4.02 or 4.03, then the party that prevails in such
action shall be entitled to receive from the opposing party (or parties) in the
action the prevailing party's reasonable attorneys' fees incurred in such action
and all costs and expenses incurred in connection therewith in accordance with
Paragraph 8.02.

                                    ARTICLE V
                             COVENANT NOT TO COMPETE

         5.01     NONCOMPETE. In consideration for the compensation to be paid
by Company to Executive, as described in Exhibit B attached hereto, Executive
agrees to the following:

                  (a)      Executive agrees that during his employment with
         Company and during the period of time ending two years after
         Executive's termination by, or resignation from, Company, (the
         "Non-Compete Period"), Executive shall not, directly or indirectly, as
         owner, partner, joint venturer, stockholder, employee, broker, agent,
         principal, trustee, corporate officer, director, licensor, or in any
         capacity whatsoever engage in, become financially interested in, be
         employed by, render any consultation or business advice with respect
         to, or have any connection with, any business engaged in the research,
         development, testing, design, manufacture, sale, lease, marketing,
         utilization or exploitation of any products or services which are
         designed for the same purpose as, are similar to, or are otherwise
         competitive with, products or services of Company in geographic area
         where, during such Non-Compete Period, the business of Company was
         being conducted or was proposed to be conducted in any manner
         whatsoever. Furthermore, Executive shall not, directly or indirectly,
         during the Non-Compete Period, request or cause any collaborative
         partners, contracting parties, suppliers, or customers with whom
         Company has a business relationship to cancel or terminate any such
         business relationship with Company or solicit, interfere with or entice
         from Company any employee (or former employee) of Company. The mere
         ownership by Executive of not more than two percent (2%) of the shares
         of stock of any corporation shall not be deemed, in and of itself, to
         violate the prohibitions of this Paragraph 5.01(a).

                  (b)      Executive acknowledges that Company conducts business
         on a world-wide basis and that, therefore, the territorial and time
         limitations set forth in this provision are reasonable and properly
         required for the adequate protection of the business of Company. In the
         event any such territorial or time limitation is deemed to be
         unreasonable by a court of competent jurisdiction, Executive agrees to
         the reduction of the territorial or time limitation to the area or
         period which such court shall deem reasonable.

                  (c)      The existence of any claim or cause of action by
         Executive against Company shall not constitute a defense to the
         enforcement by Company or any subsidiary of the foregoing restrictive
         covenants, but such claim or cause of action shall be litigated
         separately.

                                        8

         5.02     IRREPARABLE HARM. The parties acknowledge that Company will
suffer irreparable harm if Executive breaches Paragraph 5.01. Accordingly,
Company shall be entitled, in addition to any other right and remedy it may have
at law or equity, to a temporary restraining order and/or injunction, without
the posting of a bond or other security, enjoining or restraining Executive from
any violation of Paragraph 5.01, and Executive hereby consents to Company's
right to seek the issuance of such injunction. If Company institutes any such
action against Executive, alone or in conjunction with any third party or
parties to enforce any terms or provisions of Paragraph 5.01, then the party
that prevails in such action shall be entitled to receive from the opposing
party (or parties) in the action the prevailing party's reasonable attorneys'
fees incurred in such action and all costs and expenses incurred in connection
therewith in accordance with Paragraph 8.02.

         5.03     LIMIT TO EXTENT ENFORCEABLE. In the event that a court of
competent jurisdiction determines that any of the provisions of Paragraph 5.01
are unreasonable, it may limit such provision to the extent it deems reasonable,
without declaring the provision or Paragraph 5.01 invalid in its entirety. This
provision shall not be construed as an admission by Company, but is only
included to provide Company with the maximum possible protection for its
business, Confidential Information, trade secrets and data, consistent with the
right of Executive to earn a livelihood subsequent to the termination of his
employment.

                                   ARTICLE VI
                                   INVENTIONS

         6.01     DISCLOSURE. Executive shall promptly and fully disclose to
Company and will hold in trust for Company's sole right and benefit, any
Invention which Executive, during the period of his employment, makes,
conceives, or reduces to practice or causes to be made, conceived, or reduced to
practice either alone or in conjunction with others that:

                  (a)      Relates to any subject matter pertaining to
         Executive's employment;

                  (b)      Relates to or is directly or indirectly connected
         with the business, products, projects, or Confidential Information of
         Company; or

                  (c)      Involves the use of any time, material or facility of
         Company.

Any and all Inventions shall be considered "work for hire."

         6.02     ASSIGNMENT OF OWNERSHIP. Executive hereby assigns to Company
all of Executive's right, title, and interest in and to all such Inventions as
described in Paragraph 6.01 and, upon Company's request, Executive shall
execute, verify, and deliver to Company such documents including, without
limitation, assignments and applications for Letters Patent, and shall perform
such other acts, including, without limitation, appearing as a witness in any
action brought in connection with this Agreement that is necessary to enable
Company to obtain the sole right, title, and benefit to all such Inventions.

         6.03     EXCLUDED INVENTIONS. It is further agreed, and Executive is
hereby so notified, that the above agreement to assign Inventions to Company
does not apply to any invention for which no

                                        9

                  (a)      Which does not relate:

                           (i)      Directly to the businesses of Company; or

                           (ii)     To Company's actual or demonstrably
                  anticipated research or development; and

                  (b)      Which does not result from any work performed by
         Executive for Company.

         6.04     PRIOR INVENTIONS. Attached to this Agreement as Exhibit C,
which must be initialed by both parties, is a list of all of the Inventions, by
description, if any, in which Executive possesses any right, title, or interest
prior to this employment and the execution of this Agreement, which are not
subject to the terms of this Agreement.

         6.05     SPECIFIC PERFORMANCE; ATTORNEY FEES. Executive expressly
acknowledges and agrees that any violation of any terms of Paragraphs 6.01 or
6.02 may result in the issuance of a temporary restraining order and/or
injunction against Executive to effect specific performance of the terms of
Paragraphs 6.01 or 6.02. If Company institutes any action against Executive,
alone or in conjunction with any third party or parties, to enforce any term or
provision of Paragraphs 6.01 or 6.02, then the party that prevails in such
action shall be entitled to receive from the opposing party (or parties) in the
action the prevailing party's reasonable attorneys' fees incurred in such action
and all costs and expenses incurred in connection therewith in accordance with
Paragraph 8.02.

                                   ARTICLE VII
                           GOVERNING LAW; JURISDICTION

         7.01     GOVERNING LAW. The legality, validity, enforceability and

exclusive jurisdiction and venue of such courts and waive any objections they
may have at any time to such exclusive jurisdiction and venue.

                                  ARTICLE VIII

this Agreement or otherwise, at law or equity, including but not limited to, an
injunction, enjoining or restraining Executive from any violation of Paragraphs
4.02, 4.03, 5.01 and/or 6.01 or 6.02 of this Agreement.

         8.02     PAYMENT OF FEES AND EXPENSES. If any party initiates or
becomes a party to a formal proceeding, in law or equity, involving this
Agreement, and if either party obtains a substantial portion of the relief
requested by that party (the "prevailing party"), then the non-prevailing party
shall pay all of its and the prevailing party's reasonable costs and expenses,
including reasonable attorneys' fees and expenses, incurred with respect to such
proceeding. If neither party obtains a substantial portion of the relief
requested each shall bear its/his own expenses. In the event Executive is
terminated pursuant to Subparagraph 3.01(c) and determines to challenge
Company's determination of cause, Company and Executive shall each bear its/his
own expenses in connection with any proceeding initiated by Executive with
respect to the determination as to "cause".
