Agreement without the execution by the Shareholder of this Agreement;

         WHEREAS, the Shareholder's covenant not to compete as set forth in this

bargained for by Parent thereunder;

         WHEREAS, the execution and delivery of this Agreement is a condition to
the obligation of Parent to consummate the transactions contemplated by the
Reorganization Agreement;

         1. Effectiveness. This Agreement shall become effective at the Closing
of the Merger of Axe Acquisition Corporation with and into the Company pursuant
to which the Company shall become a wholly owned subsidiary of Parent (the
"Effective Date"). In the event that the Merger is not consummated, then this
Agreement shall be void and of no force and effect whatsoever.

         2. Noncompetition.

                  (a) As used in this Agreement, the following words have the
meanings defined below:

                           (i) "Affiliate" means (A) the Company (whether it
continues as a separate corporation or whether it becomes a division or other
unit of Parent or any of its subsidiaries) and (B) any other corporation,
association or other business entity of which more than 50% of the securities or
other ownership interests having voting power is owned or controlled, directly
or indirectly, by Parent.

                           (ii) "Noncompetition Period" shall mean the period
commencing on the Effective Date and ending on the date which is the later of
the third anniversary of the Effective Date or two years following the date on
which the Shareholder ceases to be employed by Parent, the Company or any other
Affiliate for any reason.

                           (iii) "Restricted Business" means the development,
marketing, sale or distribution of products or services which incorporate or are
based upon collaborative supply chain technology.

                  (b) During the Noncompetition Period, the Shareholder shall
not:

                           (i) engage in, directly or indirectly, whether as a
principal, partner, director, officer, agent, employee, consultant or in any
other capacity, or have any direct or indirect ownership interest in, any
business anywhere in the world which is engaged, directly or indirectly, in the
Restricted Business; provided, however, that this covenant not to compete shall
not preclude the Shareholder from owning, as a passive investor, up to three
percent (3%) of the outstanding shares in a publicly traded company for the
shares of which an active public trading market exists;

                           (ii) directly or indirectly induce or attempt to
influence any employee or consultant of Parent or any Affiliate to terminate his
or her employment or relationship with Parent or any Affiliate, or hire any
person who was employed as an employee or consultant of Parent or any Affiliate
during Shareholder's employment by the Company, Parent or any other Affiliate;
or

                           (iii) solicit or entice, or attempt to solicit or
entice, any clients or customers of Parent or any Affiliate or potential clients
or customers of Parent or any Affiliate for purposes of diverting their business
or services from Parent or any Affiliate.

                  (c) The covenants in this Section 2 are severable and
separate, and the unenforceability of any specific covenant shall not affect the
provisions of any other covenant. If any provision of this Section 2 relating to
the scope of the Restricted Business, the time period or geographic area of the
restrictive covenants shall be declared by a court of competent jurisdiction to
exceed the maximum scope, time period or geographic area, as applicable, that
such court deems reasonable and enforceable, said scope, time period or
geographic area shall be deemed to be, and thereafter shall become, the maximum
scope, time period or largest geographic area that such court deems reasonable
and enforceable and this Agreement shall automatically be considered to have
been amended and revised to reflect such determination.

                  (d) The Shareholder has carefully read and considered the
provisions of this Section 2 and, having done so, agrees that the restrictive
covenants in this Section 2 impose a fair and reasonable restraint on the
Shareholder and are reasonably required to protect the interests of the Company
and Parent, and their respective officers, directors, employees, and
stockholders and to preserve the goodwill of the Company purchased by Parent
pursuant to the Merger Agreement. The Shareholder acknowledges that the
noncompetition covenant set forth in this Section 2 constituted a material
inducement for Parent to enter into the Reorganization Agreement and a material
portion of the consideration bargained for by Parent thereunder, and that Parent
would not have entered into the Reorganization Agreement without the execution
by Shareholder of this Agreement. The Shareholder acknowledges and stipulates
that this Agreement was made in conjunction with the Merger pursuant to which
Parent acquired all of the outstanding equity interests of the Company and the
goodwill thereof, and that the Shareholder was the principal shareholder in the
Company and exchanged all of his Company Common Shares pursuant to the Merger.

         3. Prior Agreements. The Shareholder represents to the Company and
Parent that: (a) there are no restrictions, agreements or understandings
whatsoever to which the Shareholder is a party or by which the Shareholder is
bound which would prevent or make unlawful the Shareholder's execution of this
Agreement; (b) the Shareholder's execution of this Agreement does not constitute
a breach of any contract, agreement or understanding, oral or written, to which
the Shareholder is a party or by which the Shareholder is bound; and (c) the
Shareholder is free and able to execute this Agreement on the terms and subject
to the conditions hereof. The Shareholder acknowledges that the restrictive
covenants set forth in this Agreement are in addition to any other restrictive
covenants set forth in any other agreement between the Company and the
Shareholder.

         4. Miscellaneous.

                  (a) Indulgences, Etc. Any failure or delay on the part of
either party to exercise any right, remedy, power or privilege under this
Agreement will not operate as a waiver thereof, nor will any single or partial
exercise of any right, remedy, power or privilege preclude any other or further
exercise of the same or of any other right, remedy, power or privilege, nor will
any waiver of any right, remedy, power or privilege with respect to any
occurrence be


                                       3
