         This amendment agreement (the "Agreement") entered into this 15th day
of March, 2006 between SiriCOMM, Inc. ("SiriCOMM"), a Delaware corporation
having its principal place of business located at 2900 Davis Boulevard, Suite

liability company having its principal place of business located at 5000 Legacy
Drive, Suite 470, Plano, Texas, 75024 ("Idling Solutions").

         WHEREAS, Idling Solutions and SiriCOMM entered into the Network Access
Services Agreement (the "Network Access Services Agreement") dated February 7,
2005 which will stay in full force and effect except for the changes stated
herein;

         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 to these amended and restated terms and
conditions as follows:

         1.   SiriCOMM and Idling Solutions agree to amend the Network Access
              Service Agreement (a copy of which is attached), such that the fee
              in Section 3 is lowered from $5.00/$4.00 per truck per month
              initially to $3.00 per truck per month. Said $3.00 charge will be
              for a maximum of 1 megabyte of data on a pooled basis. Any
              overages shall be billed on a pro rata basis. In no event shall
              the charges exceed $5.00 per truck per month.

         2.   Amend Section 14 of the Network Access Services Agreement to
              include: at Idling Solutions sole discretion, if SiriCOMM does not
              provide an operational network called for in the Network Access
              Services Agreement byApril 15th, 2006 (pulling data from a test
              truck and flashing the memory with new program code into the pulse
              box via the SiriCOMM Network) and by April 30th deploy one hundred
              and fifty (150) 915 mhz base stations mutually agreed upon
              locations (so long as Cadco has made the 915 mhz radios reasonably
              available to meet the April 30th deployment and SiriCOMM will use
              best efforts to complete the balance of their sites as soon as

                                       1

              possible), then Idling Solutions is released to find an
              alternative network and to no longer be obligated to SiriCOMM to
              utilize its network. Notwithstanding anything to the contrary
              contained herein, in the event DirecTruck, a company affiliated
              with Idling Solutions, fails to deliver the technology related to
              the Pulse Box to SiriCOMM byApril 15th, 2006, SiriCOMM will have
              ten (10) days from the receipt of such technology to provide
              Idling Solutions an operational network and shall be provided an
              additional forty-five (45) days to deploy the one hundred and
              fifty (150) 915 mhz base stations. In the event SiriCOMM fails to
              meet this revised time-frame, Idling Solutions will be released to
              find an alternative network and no longer be obligated to utilize
              SiriCOMM's network.

         3.   Idling Solutions will agree to utilize the SiriCOMM network to
              exclusively carry Idling Solutions data so long as SiriCOMM
              maintains its network up to the requirements of the Network Access
              Services Agreement.

         4.   Idling Solutions has the right to purchase the Pulse Box from
              SiriCOMM for direct vendor cost plus 10%. The current vendor cost
              quote from Cadco for the Pulse Box is $330.00. It is understood
              that as the price is decreased for SiriCOMM so shall the cost to
              IS be decreased proportionately. Payment terms to SiriCOMM will be
              50% down, net 30 on orders of a minimum of 100 units. Idling
              Solutions and SiriCOMM will work together to find the best
              mutually acceptable vendor to supply the Pulse Boxes.

         5.   Idling Solutions projection of unit sales is attached as Exhibit
              A.

         6.   Should SiriCOMM declare bankruptcy, become insolvent or fail to
              deliver on a timely basis the Pulse Box to Idling Solutions, then
              Idling Solutions will have the right to buy from the SiriCOMM
              vendor under the same terms and conditions as provided to SiriCOMM
              or seek the manufacture of the Pulse Box from a third party and

                                       2

              either have access to the SiriCOMM Network or if not available for
              any reason to be able to relocate all of its customers to another
              network.

         7.   SiriCOMM will guarantee timely delivery of data to Idling
              Solutions to accommodate their needs for warranty or MERC credits,
              in accordance with the Network Services Agreement. In return,
              Idling Solutions will commit to utilize the SiriCOMM Network for
              the trucks on which the Pulse Box is installed as long as the
              network performs to standards set by the EPA for MERCs. The
              current ramp up for the 2nd quarter is 4,600 units.

         8.   As previously discussed and agreed, SiriCOMM will provide the
              requested networking equipment at the sites of J.B. Hunt's
              headquarters and terminals and on any other freight carrier which
              has more than 500 trucks and has committed to the Idling Solutions
              System.

         9.   Both SiriCOMM and Idling Solutions must mutually agree to any
              changes of the Pulse Box Design and Software for Idling Solutions
              use. Such authorization, whether requested by either Idling
              Solutions or SiriCOMM, will not unreasonably be withheld.

         10.  Except as supplemented and amended by this Agreement and such
              conforming changes as necessary to reflect the modification
              herein, all of the provisions of the Network Access Services
              Agreement shall remain in full force and effect from and after the
              effective date of this Agreement.

         NOTWITHSTANDING anything to the contrary, SiriCOMM may not knowingly
sell the Pulse Box to any trucking company or competitor of Idling Solutions,
that would utilize the pulse box to gather information for the purposes of
MERC's.

         This Agreement has been duly authorized and approved by all required
corporate action by each company and does not violate their respective
certificates of incorporation or bylaws.
