     OEM desires to sell certain products manufactured and sold by FieldWorks
and FieldWorks desires to have OEM act as its non-exclusive OEM in the sale of
such products. In consideration of these promises and the covenants contained in
this Agreement, the parties agree as follows.

     1. Appointment of OEM

          1.1 FieldWorks hereby appoints OEM as a non-exclusive OEM for
     FieldWorks' products set forth on Exhibit A (the "Products") as FieldWorks
     may amend from time to time upon notice to OEM. OEM shall be entitled to
     sell the Products only in the territory and/or markets defined in Exhibit
     B.

     maintain the Products as provided in this Agreement and agrees to abide by

     additional application software or system hardware.

     2. Ordering, Delivery, Prices and Payments

          2.1 OEM shall purchase such number of Products to meet the annual
     minimum quota set forth in Exhibit C. The failure to meet such annual
     minimum quota shall be a material breach of this Agreement.

          2.2 OEM shall purchase the Products on the annual ship schedule set
     forth as Exhibit C. Any change to the annual ship schedule shall be subject
     to the prior written approval of FieldWorks. OEM shall be entitled to use

     addition or contrary to the terms of this Agreement shall not apply. All
     orders shall be in minimum lot sizes of five (5) units.

          2.3 The prices to be paid by OEM for Products purchased under this
     Agreement shall be the prices established by FieldWorks defined in Exhibit
     D. The prices are to be determined by the annual minimum quota outlined in
     Exhibit C. FieldWorks may increase prices at any time by providing OEM with
     at least (30) days prior written notice.

     sales status, and the name, address, and phone number of all sales to
     customers along with the corresponding serial number, model number and date
     of unit purchase. OEM shall assist FieldWorks in tracing and locating
     Products upon request. To facilitate communications, OEM shall maintain at
     its facilities an industry-standard facsimile unit.

          3.3 OEM shall perform its obligations under this Agreement in
     compliance with all applicable laws. OEM shall not conduct sales or
     marketing activity outside the territory/market defined in Exhibit B and

     FieldWorks, except as authorized by FieldWorks. OEM shall not export the
     Products (or knowingly permit any third party to do so) outside of the
     United States without the prior written consent of FieldWorks.

          3.4 Except as permitted in Section 1.2, OEM shall not modify the
     Products in any manner and shall maintain Products in its inventory in a
     clean, safe and professional condition. OEM shall not reverse engineer,
     decompile or disassemble the Products and shall not knowingly allow any
     other person to do so.

          3.5 OEM agrees to, and hereby does, indemnify FieldWorks, its
     officers, directors, employees and agents against and hold each of them
     harmless from any and all claims, causes of action, damages, liabilities,
     costs and expenses (including attorneys fees) arising from any breach by
     OEM of any provision of this Agreement.

          3.6 FieldWorks may from time to time review OEM's performance under
     this Agreement. Upon request by FieldWorks, OEM shall provide FieldWorks

     period of one (1) year from the date of shipment to OEM pursuant to the
     terms of FieldWorks' then current standard product warranty. In order for
     the warranty to transfer to the customer, OEM must provide to FieldWorks
     the customer identification information identified in Section 3.2.

     Agreement shall commence as of the Execution Date and shall terminate one

     forecast for such renewal term. If the parties fail to agree in writing
     upon a renewal of this Agreement prior to the expiration of this Agreement,
     this Agreement shall automatically expire and terminate without further
     notice to either party.

     on a thirty (30) days' prior written notice to the other party.

     month period following such termination or expiration, and OEM shall
     thereafter cease selling, leasing or distributing the Products. If this
     Agreement is terminated for OEM's material breach, OEM shall cease selling,
     leasing or distributing the Products as of the effective date of such
     termination. Sections 3.3, 4 and 7 shall survive any termination or
     expiration of this Agreement.

     such information as equipment and software design information,
     documentation, prospect and customer lists, key employee names, pricing,
     discount, and commission structures, production volumes, and similar

     performance hereunder.

          7.2 The obligations set forth in Section 7.1 shall not apply to any
     information which is or becomes known to the general public, or which OEM
     can prove by written records was known to OEM at the time of its receipt
     thereof from FieldWorks, or which has been rightfully obtained by OEM from
     a third party. The provisions of this Section 7, shall survive any
     termination or expiration of this Agreement.

     8. General

          8.1 This Agreement, including the Exhibits hereto which are
     incorporated herein by reference, constitute the entire Agreement between
     the parties and supersedes all prior and contemporaneous Agreements,
     understandings, negations and discussions, whether written or oral.

          8.2 Any dispute between the parties arising out of or in connection
     with this Agreement, if not resolved by mutual agreement between the
     parties, shall be settled by binding arbitration under the rules of the
     American Arbitration Association. In the event of any such dispute or
     difference, either party may give to the other party written notice that
     the matter shall be settled by arbitration. Such arbitration shall be
     conducted in Hennepin County, Minnesota, USA. An award by arbitration may
     be entered as final judgment in any court having jurisdiction in the matter
     or application may be made to such a court for acceptance of the award and
     for an order of compliance.

     of the State of Minnesota, USA, excluding its choice of law rules.

     less exhibits, shall be in writing and signed by both parties. No failure

     deemed to be a waiver of such right in the event of the continuation or
     repetition of the circumstances giving rise to such right.

          8.6 In no event shall FieldWorks be liable to OEM, any of OEM's
     customers or any other party for loss of profits, indirect, special,
     consequential or incidental damages arising out of this Agreement, even if
     FieldWorks shall have been advised of the possibility of such potential
     loss or damage by OEM or OEM's customers. In no event shall FieldWorks be
     liable for any damages in excess of the aggregate amounts actually paid by
     OEM to FieldWorks under this Agreement.

          8.7 OEM may not assign, delegate or transfer any of its rights or
     obligations under this Agreement, without the prior written consent of
     FieldWorks. Any attempted assignment, delegation or transfer by OEM without
     such consent shall be void.

          8.8 If any provision of this Agreement is found invalid or
     unenforceable, such provision shall be deemed stricken from the Agreement
     and the remainder of the Agreement shall continue in full force and effect.

                                  OEM AGREEMENT

          8.9 This Agreement does not make either party the employee, agent or

     facsimile addressed to the respective addresses of the parties as first
     above written or at such other addresses as the respective parties may

     effective upon (1) receipt by the party to which notice is given, or (2) on
     the fifth (5th) day following mailing, whichever occurs first.

          8.11 If the performance of this Agreement or any obligation hereunder
     (other than the payment of moneys due owing hereunder) is prevented,

     State or governmental action, riots, disturbance, war, strikes, lockouts,
     slowdowns, prolonged shortage of energy or other supplies, epidemics, fire,
     flood, hurricane, typhoon, earthquake, lightning and explosion,), the party
     so affected shall be excused from such performance, only for so long as and
     to the extent that such a force prevents, restricts or interferes with the
     party's performance and provided that the party affected gives notice
     thereof to the other party and uses diligent efforts to remedy such event
     or conditions.
