               procure for the COMPANY and purchasers of the PRODUCTS from the
               COMPANY the right to continue using the PRODUCTS or portions

            of the PRODUCTS.

      4.6   Price Adjustments

            Price reductions shall be affected under normal circumstances during

            FARO prior to notification of a price adjustment the sale will be
            honored at the old price. Where the purchase order is received by
            FARO after notification of a price adjustment, the new price shall
            apply.

            Information secret and confidential and to prevent the unauthorized
            disclosure of such information by using the same degree of care, but
            no less than a reasonable degree of care, to prevent the

            of receipt from FARO; (iii) is obtained by COMPANY through
            independent research or development without reference to any
            Confidential Information; or (iv) is obtained by COMPANY from a
            third party who is in lawful possession of the information and who
            has the right to make disclosure thereof. Confidential Information
            shall not be deemed in COMPANY's possession or publicly known merely
            because it is embraced by more general information in COMPANY's
            possession or because it is embraced in general terms in
            publications or patents. In addition, Confidential Information
            consisting of a combination of features shall not be deemed to be
            within the exceptions set forth in clauses (i) - (iv) above merely
            because individual features are in the public domain or in the
            possession of COMPANY

            of Confidential Information will expire 3 years from the date that
            item of Confidential Information is first received by COMPANY from
            FARO. This Agreement shall not in and of itself require FARO to
            disclose Confidential Information to COMPANY. Confidential
            Information will remain the property of FARO notwithstanding
            disclosure hereunder. Upon demand by FARO, COMPANY shall return to
            FARO any and all tangible embodiments of Confidential Information
            requested by FARO.

      9.1   In addition to any other remedies that the parties may have by law
            or pursuant to this agreement, the prevailing party in any
            litigation or other effort to enforce or interpret this Agreement
            shall be entitled to recover its reasonable attorney's fees and the
            costs and expenses of litigation, including such fees and costs as
            may be incurred before trial, at trial, in bankruptcy and creditor's

10.0  APPLICABLE LAW

            This agreement shall be governed by and interpreted in accordance
            with the laws of the State of Florida.

11.0  RELATIONSHIP BETWEEN FARO AND COMPANY

      11.1  The purpose of this agreement is to establish a OEM purchase
            arrangement between FARO as the manufacturer of PRODUCTS and COMPANY
            as a manufacturer and seller of metrology hardware and software
            products that have applications to the PRODUCTS. FARO does not
            intend to and is not selling to COMPANY a "franchise" or "business
            opportunity" as such terms are defined by applicable law. COMPANY
            hereby represents and warrants to FARO that COMPANY already engages
            in an established business of the development, manufacture and sale
            of metrology hardware and software products and is not looking to
            FARO to establish any type of system to sell PRODUCTS nor to
            establish a new business in reliance upon FARO. COMPANY acknowledges
            that no fee has been paid to FARO as consideration for entering into
            this agreement and that the only consideration that will be paid to
            FARO is the purchase price of PRODUCTS purchased from FARO in
            accordance with Section 4.0 of this Agreement.

      11.2  COMPANY is an approved OEM purchaser of PRODUCTS only and not an
            agent of FARO for any purpose. COMPANY has no authority to bind FARO
            to any contract or agreement with any party for any reason.

      11.3  The relationship between COMPANY and FARO is defined solely by this
            Agreement and all prior agreements, (oral or written) letters of
            understanding, or

                                       9



            other writings not binding on COMPANY or FARO. This agreement may
            only be changed in a written instrument executed by COMPANY and
            FARO.

12.         COUNTERPARTS

            This Agreement shall be drawn up in two copies and signed by both
            parties thereto. Each party shall receive one fully executed copy.
