productivity and enhance safety and security. Specific components of the
proposed transaction include:

          installation of broadband data networks in locations such as truck
          stops, weigh stations, ports of entry, etc. SiriCOMM hot spots will be
          accessible to all Christenson users that are registered subscribers.

          network maintenance, and the customer service center.

     3.   Services. SiriCOMM will provide BEACON software and one PDA for each

          from the tractor's J1708 and/or J1939 data bus. The PULSE hardware
          requires installation on each tractor, which typically requires less
          than 30 minutes.

          amp power source, and reasonable access to the facilities for
          authorized service personnel.

     6.   Additional Services. SiriCOMM will provide "Train The Trainers"
          curriculum as well as appropriate materials.

of the agreement.

     1.   The PULSE hardware cost should not exceed $200:00 for each tractor and
          installation cost will vary depending on where the unit is installed.
          SiriCOMM anticipates the actual price per unit will be less than

<PAGE>

          $200.00 and will pass that savings on to Christenson. Christenson
          maintains ownership of the equipment and may remove and reinstall into
          another tractor at the company's discretion.

                           MEMORANDUM OF UNDERSTANDING

         This Memorandum of Understanding (this "memorandum") has been executed
by and between SiriCOMM, Inc. ("SiriCOMM"), a Delaware corporation whose
principal place of business is located in Joplin, MO, and Mark Sullivan
("Sullivan"), an individual. This memorandum shall be binding upon all parties
hereto until such time as the parties enter into a mutually agreeable definitive
and final agreement setting forth the terms hereof and such other terms or
provisions as the parties shall agree, at which time this memorandum shall then
and thereafter be null and void except, in each case as otherwise provided
herein.

         WHEREAS, SiriCOMM is in the process developing software applications
and a broadband wireless network infrastructure for the commercial
transportation industry market that, when developed, will allow users to connect
to the SiriCOMM network through wireless transmission and receiving equipment
installed in strategic locations that will include, but not be limited to, truck
stops and weigh stations; and

         WHEREAS, Sullivan has consulted and desires to continue to consult with
SiriCOMM in the development of its wireless network infrastructure, its software
applications, and certain other related products;

         NOW THEREFORE, for and in consideration of the premises, and other good
and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties agree as follows:

         1.       Sullivan will provide consulting services to SiriCOMM based
                  upon specific and mutually agreed upon projects. These
                  projects will be described in "Scope of Work" documents. The
                  scope of work for the first of these projects, the "Driver
                  Email System", is attached to this memorandum as "Attachment
                  A". Scopes of work for additional projects will be drafted by
                  joint effort of the parties for attachment to the definitive
                  agreement;

         2.       As the parties agree that time is of the essence, Sullivan
                  will immediately begin work on the Driver Email System. This
                  work will be commenced in anticipation of the final scope of
                  work, compensation schedule, and definitive agreement.
                  Sullivan accepts the risk that the final scope of work will
                  cause some of this work in anticipation to be omitted from the
                  final scope of work and associated compensation;

         3.       SiriCOMM will make its best efforts with its strategic
                  partner, Idling Solutions, LLC, to mitigate the Sprint

                  Services, Inc, a Missouri corporation wholly owned and
                  controlled by Sullivan. The nature of and final approval of
                  such mitigation will be at Thorium's sole discretion. To the
                  extent that such mitigation is successful, Sullivan will cause
                  Thorium to correspondingly forgive or modify SiriCOMM's
                  obligations under a separate "Internet Access Service
                  Agreement" between the SiriCOMM and Thoruim;

                  will designate Thorium as it's exclusive provider of Internet
                  access services delivered through the local loop of the public
                  telephone network;

<PAGE>

         5.       SiriCOMM will work with Sullivan to develop new collateral
                  projects/products to be sold through the SiriCOMM sales
                  channels. Potential collateral projects include trailer
                  tracking devices/software, dynamic CRM software, etc.;

         6.       As compensation for various services performed by Sullivan for
                  SiriCOMM in the past, SiriCOMM will issue to Sullivan,
                  concurrent with the signing of this memorandum, warrants to
                  purchase 150,000 shares of common stock. The warrants will
                  have a 3-year life and will be exercisable at a $3.40 per
                  share price and will be transferable;

         7.       Compensation for the consulting services described in (1) and
                  (2) above will be at a mutually agreed rate negotiated in
                  conjunction with the total scope of work under the definitive
                  agreement. Whatever the amount, the form of such compensation
                  shall be additional warrants to purchase common stock issued
                  each subsequent quarter following execution of the definitive
                  agreement. The quarterly warrants will have a 3-year life and
                  will be exercisable at the weighted average bid price for the
                  10 days prior to issue;

         8.       The term of the definitive agreement will be five years unless
                  terminated earlier by the parties under mutual agreement. In
                  addition, either party may terminate the agreement based upon
                  the other party's non-performance subject to a 30-day cure
                  period; and

         9.       The definitive agreement will contain standard and mutually
                  agreeable language covering: conflict resolution,
                  indemnifications, etc.

         This memorandum of understanding shall have a term of one year, subject
to earlier termination (i) on the date the parties enter into a mutually
agreeable definitive and final agreement setting forth the terms hereof and such
other terms or provisions as the parties shall agree, at which time this

otherwise provided herein, or (ii) in the event either party breaches the terms
hereof, then the failure of the breaching party to cure such breach within 30
days following notice of such breach by the non-breaching party.
