THEREFORE, in consideration of the mutual covenants hereinafter set forth, the
parties to this Strategic Alliance Agreement agree as follows:

1.    Strategic Alliance. The parties agree to work together in good faith, on a
      best efforts basis, to further develop and market on a worldwide basis, as
      quickly as practical, the family of drug and alcohol testing optical card
      products, developed by BSIX, named 'DISA 2000'.

      control for the petroleum and chemical industries; administration of
      worker's compensation; insurance for construction sites; and construction
      contractor consortiums (collectively 'Exclusive Markets'). BSIX agrees
      that it will not, during the term of this Strategic Alliance Agreement,
      design, market, or sell, either solely or in partnership or cooperation

      preauthorization of BSIX.

3.    Responsibilities of BSIX. BSIX agrees that it will use its best efforts

      selling product into the Exclusive Markets. BSIX agrees that it will be

      transaction processing units as modified for the Exclusive Markets
      provided that BSIX has agreed to make such modifications.

      2000 family of optical card products into the Exclusive Markets. DISA
      expects to make an investment over the next five years of approximately
      $5.0-million to market the DISA 2000 family. Further, the Parties
      acknowledge that DISA has created a five (5) year business plan that
      reflects the intent of DISA incorporating approximately 60-70 sales
      professionals operating in the Exclusive Markets. These sales
      representatives will promote the sales and support of DISA 2000 as an
      integral part of the DISA product offering.

5.    Ownership of Technology. The parties agree that ownership of all
      associated technology, already developed or to be developed, will not
      change as a result of this Strategic Alliance Agreement. The parties agree
      that BSIX will retain all rights and ownership of all software and
      hardware technology and all patents, that it has already developed or will
      develop, that is contained within or used by the optical card transaction
      processing units.

      effective on the date hereinabove first shown and the term of the
      Strategic Alliance Agreement shall be for five (5) years after the
      effective date of the Strategic Alliance Agreement unless mutually
      extended, in writing, by the parties or canceled as allowed in paragraph 9
      titled Termination of Agreement.

7.    Confidential Information. The parties acknowledge that certain business or
      technical information that may be disclosed by either party to the other
      represents valuable, proprietary, and trade secret information that is the
      property of the disclosing party. Such information includes, but is not
      limited to, unpublished product specification and related technical data
      such as drawings, data, source computer programs, software, and other
      items; customer lists; marketing plans; the internal organization,
      business relationships and other affairs of the disclosing party; and
      other items (hereinafter `Proprietary Information'). The parties agree,
      that during the course of this Strategic Alliance Agreement, and at all
      times thereafter, as specified herein, to keep all Proprietary Information
      confidential which disclosing parties indicate, in writing, at the time of
      disclosure, to be proprietary, and to not disclose Proprietary Information
      to any third party without the express written approval of the disclosing
      party other than to those employees or agents that must have access to
      Proprietary Information in order to effectively perform the obligations
      under the Strategic Alliance Agreement. The parties each agree to take the
      same steps that they each utilize to protect their own similar proprietary
      information, but in any event not less than reasonable means, to protect
      all Proprietary Information received hereunder. The obligations of the
      parties that receive Proprietary Information, as set forth above, shall
      not apply to any disclosed information that appears in any printed or
      recorded public publication or that ceases to be proprietary other than by
      disclosure by any party; or that can be shown, by documentary evidence, to
      have been in the possession of a receiving party, prior to receipt
      hereunder; or that is available or becomes available, without restriction
      to the receiving party, from a source independent of the disclosing party;
      or that is agreed to be unrestricted by the disclosing party in writing;
      or that is developed independently by the receiving party; or that is
      required to be disclosed by the recipient party by a government agency or
      other legal authority, so long as the recipient party provides the
      disclosing party with written notice of the required disclosure promptly
      upon receipt of notice of the required disclosure; or that is not received
      by the receiving party, in tangible form and conspicuously marked
      `proprietary', `confidential' or some such similar designation. The
      obligations of the receiving party with regard to Proprietary Information
      shall survive the termination or expiration of this Strategic Alliance
      Agreement for a period of three (3) years.

8.    Terms of Sales, Pricing and Commissions.

      (a)   DISA 2000 Systems. The parties agree that DISA shall purchase the
            DISA 2000 from BSIX for resale to third parties; provided, that any
            such transaction shall be limited so as to only embody a license to
            the end user to use any software, firmware, or similar intellectual
            property incorporated into the DISA 2000, and any "bill of sale" or
            purchase order shall so reflect such restricted terms of sale. The
            parties also agree that the initial list pricing of the BSIX systems
            sold by DISA will be $       per optical card; $            for
            standard DISA 2000 transaction terminals; $             for
            enrollment DISA 2000 terminals; and $             per transaction.
            DISA shall not represent anything to the contrary in connection with
            such transactions, and shall indemnify and hold BSIX harmless from
            any breach of this provision. DISA shall pay BSIX for the DISA 2000
            in an amount equal to a       discount from the price that DISA
            sells the DISA 2000 to such third party; provided, however, that
            BSIX shall establish a minimum price to be received by BSIX for DISA
            2000 product (including all components and accessories for use
            therewith), so as to assure that BSIX is not required to sell the
            DISA 2000 system at less than BSIX's cost, plus a reasonable markup.
            BSIX shall provide DISA with a current schedule setting forth the
            minimum price to be received by it from time to time, and BSIX may
            change such pricing on 60 (sixty) days prior written notice to DISA,
            which shall become effective for all purchase orders received from
            DISA after its effective date (but no less than 60 (sixty) days
            after such schedule is provided to DISA). Payment to BSIX by DISA
            shall be due on a Net 30 days basis unless negotiated otherwise on a
            case-by-case basis. BSIX will consult with DISA in advance prior to
            any change in pricing to be effected hereunder. Risk of loss shall
            pass to DISA upon delivery of DISA 2000 systems to DISA or to the
            end customer, as the case may be. No purchase order submitted by
            DISA to BSIX that contains terms that are contrary to these general
            provisions shall be binding on BSIX. No purchase order submitted by
            DISA to BSIX shall be binding on BSIX until accepted by BSIX. The
            DISA 2000 shall be warranted to the end user by BSIX according to a
            one (1) year term. Warranty service during the term of such warranty
            shall be at the expense of BSIX, pursuant to its standard warranty.

      (b)   Accessories. The parties agree that accessories (such as optical
            cards) that are used in conjunction with the DISA 2000 or
            stand-alone maintenance agreements may be purchased from BSIX by
            DISA on the same pricing terms as the DISA 2000 systems.

      (c)   Transaction Fees. The parties acknowledge that an integral component
            of the transaction involving the sale of a DISA 2000 is ongoing
            transaction fees paid to DISA by the end user of the DISA 2000
            system. BSIX shall be paid       percent       of such transaction
            fees generated by the DISA 2000. Payment shall be due to BSIX thirty
            (30) days after such fees are received from the end user by DISA.
            Such payments shall continue for the life of the installed systems
            sold by DISA.

9.    Termination of Agreement. This Strategic Alliance Agreement, other than as
      limited by the above paragraph 7 titled Confidential Information, shall
      automatically terminate upon the happening of any one of the following
      events: (a) A party ceases to actively carry on business; (b) A party
      fails to remedy a default of any of the terms, covenants or conditions,
      contained in this Strategic Alliance Agreement, within thirty (30) days
      after being requested, in writing by the other party, to do so; or (c) A
      party becomes insolvent, exercises an assignment for the benefit of
      creditors, goes into liquidation, or has a trustee appointed for the
      benefit of creditors. The parties agree that BSIX has the right to
      terminate this Strategic Alliance Agreement if amounts received by BSIX
      hereunder are less than $            , $            , $            , and
      $             in the years 2001, 2002, 2003, and 2004 respectively. In the
      event of termination of this Strategic Alliance Agreement, for any reason,
      each party shall return all


                                       3
<PAGE>

      Proprietary Information and any loaner equipment to the other party within
      10 days of such termination.

            Agreement be held by a court of law to be illegal, invalid, or

            the remaining provisions of this Strategic Alliance Agreement shall
            not be affected or impaired thereby.

      (b)   Waiver. The failure of any party to enforce any of the terms and
            conditions of this Strategic Alliance Agreement shall not constitute
