         THIS STOCK REPURCHASE OPTION AGREEMENT (this "Agreement"), made as of
the 15th day of August, 2003 (the "Date of Grant"), between Minorplanet Systems
USA, Inc., a Delaware corporation (the "Company"), and The Erin Mills Investment
Corporation, a Canadian corporation ("Erin Mills").

         Pursuant to that certain Stock Purchase and Sale Agreement by and
between Erin Mills and Minorplanet Systems, PLC, a United Kingdom public limited
company, dated the date hereof, Erin Mills acquired 20,378,517 shares ("Shares")
of the Company's Common Stock, par value $0.01 per share ("Common Stock"). Erin
Mills desires to grant the Company an option to repurchase 19,378,517 of its
Shares on the terms and conditions set forth herein. Capitalized terms not
otherwise defined herein shall have the meanings set forth in Section 19.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
promises, covenants and agreements hereinafter set forth and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto, intending to become legally bound, agree as
follows:

1.       Grant of the Stock Option. Erin Mills hereby grants to the Company the
         right and option to repurchase, on the terms and conditions hereinafter
         set forth, 19,378,517 of the Shares (subject to adjustment as provided
         in Section 9 hereof, the "Stock Option"). The purchase price for the
         Shares shall be equal to $0.01 for every 1,000 Shares acquired by the
         Company (the "Exercise Price"), for an aggregate Exercise Price of
         $193.79.

2.       Stock Option Term. The term of the Stock Option shall commence on the
         date hereof and continue until August 15, 2013.

3.       Exercisability and Vesting of the Stock Option. All Shares included in
         the Stock Option shall be 100% vested upon grant. Notwithstanding the
         foregoing or any other provision to the contrary contained herein, the
         Company may not exercise all or any part of the Stock Option at any
         time in which the Company (by virtue of the knowledge of its executive
         officers and directors) is in possession of material non-public
         information with regarding or respect to itself.

4.       Exercise of the Stock Option. Subject to Section 12 of this Agreement,
         the Stock Option may be exercised in whole, or in part from time to
         time by the Company; provided that the minimum number of Shares for
         which the Stock Option may be exercised is 1,000 Shares (subject to
         adjustment as provided in Section 9 hereof) or such lesser number as
         may remain subject to the Stock Option. The exercise of the Stock
         Option or any part thereof shall be evidenced by a notice in writing by
         the Company to Erin Mills, and shall state the number of Shares desired
         to be repurchased by the Company in that particular exercise. The
         Exercise Price of the Shares as to which the Stock Option shall be
         exercised shall be paid in full at the time of exercise, and shall be
         paid to Erin Mills in cash (including check, wire transfer, bank draft,
         or money order).



5.       Representations and Warranties of Erin Mills. Erin Mills hereby
         represents and warrants to the Company as follows:

         (a)      Title to Shares. Erin Mills is the sole holder of record and
                  beneficial owner of all 19,378,517 Shares of Common Stock.
                  There are no outstanding warrants, options, rights of refusal
                  or otherwise, agreements, calls or other commitments or
                  similar agreements (in each case, to which Erin Mills is a
                  party) relating to, providing for or prohibiting the sale,
                  conveyance, transfer, gift, pledge, mortgage or other
                  disposition or encumbrance or the granting or permitting any
                  person, corporation, partnership, limited liability company,
                  trust or other entity to acquire the Shares, or any part
                  thereof, except as provided by this Agreement. Upon valid
                  exercise of the Stock Option in full as herein provided and
                  delivery of the duly executed and endorsed certificates
                  representing the Shares to the Company, the Company shall
                  acquire full legal and beneficial ownership of 19,378,517
                  Shares (subject to adjustment as provided in Section 9 hereof)
                  free and clear of any and all Liens.

         (b)      Capacity of Erin Mills; Execution of Agreement. Erin Mills has
                  the absolute and unrestricted right, power, authority and
                  capacity to enter into this Agreement and to perform the
                  obligations required to be performed by Erin Mills hereunder.
                  This Agreement has been duly executed and delivered by, and
                  constitutes the valid and legally binding obligation of Erin
                  Mills, enforceable against Erin Mills in accordance with its
                  terms, except as may be limited by applicable bankruptcy,
                  insolvency or similar proceedings and general principles of
                  equity.

         (c)      No Brokers. Erin Mills has not employed any person who could
                  claim a brokerage commission or other fee in connection with
                  either the negotiation or execution of this Agreement or the
                  consummation of the transactions effected hereby.

         (d)      Sophisticated Seller. Erin Mills is a sophisticated seller
                  with respect to the Shares, has adequate information
                  concerning the business and financial condition of the Company
                  and its properties to make an informed decision regarding this
                  Agreement and has independently, based upon such information
                  as it deemed appropriate, made its own analysis and decision
                  to enter into and consummate this Agreement, after it has had
                  opportunities to ask questions of the Company and receive
                  answers to its satisfaction. Erin Mills has voluntarily
                  entered into this Agreement for valuable consideration and not
                  by reason of duress (financial or otherwise), fraud, undue
                  influence or mistake, and it is not in a significantly
                  disparate bargaining position.

         (e)      No Knowledge of Information. As of the date hereof, Erin Mills
                  is not in possession of any material, non-public information
                  regarding or with respect to the Company.



6.       Representations and Warranties of the Company. The Company represents
         and warrants to Erin Mills as follows:

         (a)      Authority of the Company; Execution of the Agreement. The
                  Company has the absolute and unrestricted right, power,
                  authority and capacity to enter into this Agreement and to
                  perform the obligations required to be performed by the
                  Company hereunder. This Agreement has been duly executed and
                  delivered by, and constitutes the valid and legally binding
                  obligation of the Company, enforceable against the Company in
                  accordance with its terms, except as may be limited by
                  applicable bankruptcy, insolvency or similar proceedings and
                  general principles of equity.

         (b)      No Knowledge of Information. On the date of any exercise of
                  the Stock Option by the Company, the Company will not be in
                  possession of any material, non-public information regarding
                  or with respect to itself.

7.       Certain Matters with Respect to the Shares. Erin Mills hereby covenants
         and agrees at all time during the term of this Agreement (i) to
         maintain ownership, beneficially and of record, of a number of Shares
         equal to the number of Shares necessary to satisfy the exercise in full
         of the Stock Option by the Company, (ii) to continuously own such
         Shares free and clear of any and all Liens (as defined below), and
         (iii) to not enter into (or agree to enter into) any Agreement granting
         to any other person or entity a warrant, option, right of first
         refusal, call, right, or similar rights with respect to any of the
         Shares that are subject to the Stock Option, or granting any right to
         purchase, transfer, or otherwise acquire any of the Shares that are
         subject to the Stock Option.

8.       Rights as Stockholder. The Company will have none of the rights or
         privileges of a stockholder of the Company (as treasury stock) in
         respect of any of the Shares of Common Stock subject to the Stock
         Option unless and until the third Business Day following the valid
         exercise of the Stock Option, and the Company will not be deemed to
         hold or own, beneficially or otherwise, such Shares (subject that
         exercise) until that time.

9.       Adjustments upon Changes in Capitalization or Reorganization. The
         number of Shares included in the Stock Option shall be adjusted from
         time to time as follows:

         (a)      Subject to any required action by stockholders, the number of
                  Shares covered by the Stock Option, and the Exercise Price,
                  shall be proportionately adjusted for any increase or decrease
                  in the number of issued Shares resulting from a subdivision or
                  consolidation of Shares or the payment of a stock dividend
                  thereon.

         (b)      Subject to any required action by stockholders, if the Company
                  shall not be the surviving corporation in any merger or
                  consolidation, the Stock Option shall pertain to and apply to
                  the securities to which a holder of the number of Shares
                  subject to the Stock Option would have been entitled in
                  connection with the merger or consolidation, and if a plan or
                  agreement reflecting any such event is in effect that
                  specifically provides for the change, conversion, or exchange
                  of



                  Common Stock, then any adjustment to Shares relating to the
                  Stock Option hereunder shall be consistent with the terms of
                  any such plan or agreement.

         (c)      In the event of a change in the Common Stock as presently
                  constituted, which is limited to a change of par value into
                  the same number of shares of Common Stock with a different par
                  value or without par value, the Common Stock resulting from
                  any such change shall be deemed to be the Shares within the
                  meaning of this Agreement.

         (d)      In the event of an equity restructuring transaction, such as a
                  spinoff or recapitalization through a special, large, and
                  nonrecurring dividend, the exercise price and number of Shares
                  purchased on the exercise of this Stock Option may be adjusted
                  in order to maintain the participant in the same economic
                  position as before the equity restructuring transaction,
                  provided that:

                  (i)      The aggregate intrinsic value (difference between the
                           market value per Share and the Exercise Price) of the
                           Stock Option immediately after the change is not
                           greater that the aggregate intrinsic value of the
                           Stock Option immediately before the change; and

                  (ii)     The ratio of the Exercise Price to the market value
                           per Share is not reduced.

                  To the extent that the foregoing adjustments relate to stock
                  or securities of the Company, such adjustments shall be made
                  by the Board (as defined below) and the Company shall deliver
                  notice to Erin Mills of such adjustment made by the Board
                  within 10 Business Days thereafter.

         (e)      The grant of the Stock Option shall not affect in any way the
                  right or power of the Company to make adjustments,
                  reclassifications, or changes of its capital or business
                  structure or to merge or to consolidate or to dissolve,
                  liquidate, or sell or transfer all or any part of its business
                  or assets.

10.      Non-Transferability of the Stock Option. Any attempted assignment,
         transfer, pledge, hypothecation, or other disposition of the Stock
         Option, or the levy of any execution, attachment, or similar process
         upon the Stock Option shall be null and void and without effect.

11.      Transfer of Shares. Upon the valid exercise of the Stock Option as to
         any of the Shares subject to the Stock Option, Erin Mills shall
         surrender to the Company all certificates representing Shares that are
         being acquired by the Company by the present exercise thereof, duly
         endorsed by Erin Mills to the Company or in blank, at the Company's
         principal executive offices, within three (3) Business Days of receipt
         of a notice of exercise from the Company. All certificates surrendered
         by Erin Mills shall be accompanied by such other instruments of
         transfer as may be reasonably required by the Company. Upon valid
         exercise of the Stock Option, the Board shall cause the Secretary of
         the Company to reflect such shares as treasury shares until further
         directed.



12.      Restrictions on Exercise. Notwithstanding any provision to the contrary
         contained herein, the Stock Option shall not be exercisable unless and
         until the occurrence of the closing of the transactions contemplated by
         that certain Binding Letter Agreement, dated the date hereof, among
         Minorplanet Systems USA, Inc., Minorplanet Systems PLC, and Minorplanet
         Limited.
