BID. SBMS will maintain the HighwayMaster BID for NPA/NXXs solely for the use of HighwayMaster as permitted by any laws, rules or regulations. The BIDs will permit identification of Units in each Market as permitted by any laws, rules or regulations. 2.2. Operational Services. 2.2.1. Visibility. SBMS will provide HighwayMaster with access to Visibility services for the HighwayMaster BID, subject to its ability to obtain GTE-TSI's consent to do so. 2.2.2. SBMS will provide, or cause to be provided, to HighwayMaster CIBER in collect tapes reflecting CTS Usage associated with the HighwayMaster BID, subject to its ability to obtain GTE-TSI's consent to do so. Whether SBMS provides the tapes or causes them to be provided directly to HighwayMaster by GTE-TSI shall be decided in SBMS's sole discretion, as it deems appropriate or feasible from time to time. 2.2.3. Within thirty (30) days of the end of each settlement cycle, SBMS will provide HighwayMaster with a financial summary consisting of charges by ADMINISTRATIVE CARRIER AGREEMENT PAGE - 4 5 SBMS Carriers and Non-SBMS Carriers for CTS Usage associated with the HighwayMaster BID in each Carrier's respective Markets during that settlement cycle, subject to its ability to obtain GTE-TSI's consent to do so. SBMS will also provide CHARM Reports to back up the summary, also subject to GTE-TSI's consent. 2.2.3.1.

SBMS shall act as HighwayMaster?s payment agent for purposes of timely paying any and all net settlement amounts charged by Carriers with respect to NPA/NXXs and/or BID(s) assigned to HighwayMaster or its End-Users in the Carrier?s Market ("Carrier Charges"). The parties acknowledge and understand that SBMS is merely acting as the payment agent of HighwayMaster in connection with the CIBERNET net settlement process and that HighwayMaster is solely liable for any and all amounts due Carriers for CTS Usage with respect to the HighwayMaster BID. 2.3.2. Reimbursement. HighwayMaster shall reimburse SBMS for any and all amounts paid by SBMS to Carriers for Carrier Charges, regardless of whether such charges were improperly invoiced or not.

Improper Billing by Carriers. From time to time, various carriers incorrectly rate or charge for CTS Usage for cellular service provided to End-Users in their Market. The parties anticipate that most Carriers will sign the IRSA Addendum in the form of that attached hereto as Exhibit 1. In those cases, HighwayMaster will bear all responsibility for seeking refunds for overcharges from the Carriers and for making payments to Carriers for undercharges, and will do so outside of the CIBERNET settlement process. With respect to any Carrier(s) that are unwilling to sign the Exhibit 1 form of IRSA Addendum solely because of the paragraph 3 adjustment language ADMINISTRATIVE CARRIER AGREEMENT PAGE - 5 6 therein, SBMS agrees to modify that language, and SBMS and HighwayMaster agree to cooperate in implementing a mutually acceptable mechanism for SBMS to facilitate refunds from those Carriers for improperly rated or charged CTS Usage. 2.3.4. HighwayMaster agrees to indemnify and hold harmless SBMS from any and all claims, losses, damages, causes of action, costs (including reasonable attorney's fees) or reasonable expenses incurred by SBMS as a result of any claim or action brought by a third party and arising from the payment of amounts to Carriers under this Agreement. 2.3.5. Alternative Billing Arrangements. Nothing herein restricts HighwayMaster from entering into separate agreements with Non-SBMS Carriers to establish alternate standards, processes and arrangements by which HighwayMaster would settle and be billed for the use of such Non-SBMS Carrier's CTS ("Alternative Billing Arrangements"), provided, that HighwayMaster shall not be relieved of any of its obligations hereunder. SBMS shall have no obligation to provide any Services or assistance to HighwayMaster in connection with the Alternative Billing Arrangement. 2.4. Provision of CTS. 2.4.1. SBMS Markets. HighwayMaster hereby authorizes SBMS and SBMS agrees that it will negotiate and execute IRSA Addenda and cause HighwayMaster to be provided with CTS in the SBMS Markets under the same terms (other than rates) that it negotiates such CTS access in Non-SBMS Markets. To the extent that an SBMS Market loses the required FCC license or other necessary approvals, such SBMS Market shall have no obligation to provide CTS to HighwayMaster. 2.4.2. Non-SBMS Markets. HighwayMaster hereby authorizes SBMS and SBMS agrees that it will use commercially reasonable efforts to negotiate and execute IRSA Addenda in substantially the form of that attached hereto as Exhibit 1 to cause HighwayMaster to be provided with CTS in the Non-SBMS Markets. SBMS shall ensure that its IRSA Addenda with the Non-SBMS Carriers permit for rating of End-User CTS at the rates set forth in HighwayMaster's CSAs with the Non-SBMS Carriers. SBMS will have no liability to HighwayMaster or any third party for its failure to obtain IRSA Addenda from any particular Carriers or from any particular number of Carriers either before or after the Cutover Date. The terms and conditions of all IRSA Addenda are confidential and proprietary to SBMS and are subject to the provisions of this Agreement relating to SBMS Information.

Technical Data Updates. SBMS and HighwayMaster will issue a joint technical update to the Carriers explaining the transition from HighwayMaster's prior administrative carrier to SBMS. HighwayMaster shall compose and provide additional technical data updates to all carriers at least two (2) times per year, provided that HighwayMaster shall not release any updates without prior written approval from SBMS, which approval shall not be unreasonably withheld. 5.9. Technical Data Sheets. HighwayMaster will request and maintain technical data sheets from Carriers for trouble resolution and record maintenance. 5.10. CTS Restrictions. HighwayMaster, and not SBMS, shall be responsible for informing Carriers of any required call restrictions with respect to the HighwayMaster NPA/NXXs or Units, [Text has been omitted pursuant to a request for confidential treatment.

P. - Operations -------------------------- Date: March 30, 1999 -------------------------- SOUTHWESTERN BELL MOBILE SYSTEMS, INC. A VIRGINIA AND DELAWARE CORPORATION By: (x) Lisa Guarnacci for Frank Boyer ----------------------------- Name: Frank Boyer --------------------------- Title: V. P. Product Development -------------------------- Date: March 30, 1999 -------------------------- ADMINISTRATIVE CARRIER AGREEMENT PAGE - 18 19 EXHIBIT 1 ADDENDUM TO INTERCARRIER ROAMER SERVICE AGREEMENT This Addendum is made by and between SOUTHWESTERN BELL MOBILE SYSTEMS, INC. on behalf of itself and its affiliates ("SBMS") AND [FILL IN CARRIER NAME], on behalf of itself and its affiliates ("CARRIER"). WHEREAS, SBMS has signed an Administrative Carrier Agreement ("ACA") with HighwayMaster Corporation ("HighwayMaster"); WHEREAS, Carrier desires to facilitate the provision of cellular roamer service to end users of the HighwayMaster System and has signed or intends to sign a Cellular Service Agreement with HighwayMaster to set rates and other terms and conditions of the service to be provided by Carrier to HighwayMaster's end users; WHEREAS, in recognition of the unique requirements of HighwayMaster's end users, including members of the long haul trucking industry and other similarly situated industries with nomadic travel patterns, the Parties hereto have assented to amend the IRSA(s) in accordance with the provisions set forth herein; NOW, THEREFORE, it is agreed as follows: 1. This Addendum shall amend the Intercarrier Roamer Service Agreement(s) listed on Attachment A hereto (the "IRSA(s)"), along with any replacement intercarrier roamer service agreements intended to replace, modify or supersede the IRSAs. The provisions set forth herein are incorporated by reference and shall become a part thereof. In the event that the IRSA(s) is assigned in accordance with its terms, this Addendum shall be assigned along with the IRSA(s). 2. Pursuant to the provisions herein stated, Carrier agrees for the term of this Addendum to provide roaming service in accordance herewith in those cellular markets set forth on Attachment B at the rates established by and between Carrier and HighwayMaster. It is expressly understood and agreed that SBMS shall have no responsibility for negotiating or setting rates for the service to be provided by Carrier to HighwayMaster End Users. 3. SBMS is providing administrative and settlement functions for HighwayMaster. SBMS shall participate with Carrier in the net settlement process and provide the settlement funding account with respect to the HighwayMaster BID(s). Notwithstanding the foregoing, HighwayMaster is the party ultimately responsible for all of the cost of services for system usage on Carrier's systems, at the rates set between HighwayMaster and Carrier. Therefore, both parties agree that any disputes or adjustments regarding Carrier's charges with respect to the HighwayMaster BID(s) shall be handled directly between Carrier and HighwayMaster, and that any mechanisms created by CIBERNET to adjust charges related to billing through the Net Settlement Program will not be used with respect to the HighwayMaster BID. HighwayMaster shall be entitled to seek amounts for any 1 20 overcharges directly from Carrier, and Carrier shall be required to seek amounts for any undercharges directly from HighwayMaster, and not SBMS. 4. SBMS shall notify Carrier of the NPA/NXX combinations created solely for use by roamers as defined herein, which NPA/NXXs will be associated with a unique HighwayMaster billing identification ("BID") assigned to SBMS. The NPA/NXX's are not dialable from the Public Switched Telephone Network and can only be successfully called through the HighwayMaster Network Services Center. The HighwayMaster BID will be used nationally to identify vehicles equipped with the HighwayMaster system. HighwayMaster will provide Carrier with all updates of NPA/NXXs used for the purposes of this application. HighwayMaster will provide Industry Standard Updates which shall be listed on HighwayMaster's Technical Data Sheets. All assigned numbers will be stored in a validation database, jointly maintained by TSI and HighwayMaster. HighwayMaster shall provide activations, ESN changes and updates to the database. 5. Term and Termination. 5.1. The term of this Addendum shall commence on the later of (a) the Cutover Date under the ACA (which shall be no later than December 20, 1999); (b) the effective date of the Cellular Service Agreement between Carrier and HighwayMaster; or (c) the date that the HighwayMaster BID and NPA/NXXs are transferred from HighwayMaster's current administrative carrier to SBMS; and shall continue for an Initial Term of one (1) year. Thereafter, it shall renew for successive one year terms, provided that either Party may terminate this Addendum by providing written notice of termination to the other at least sixty (60) days prior to the end of the Initial Term or any Renewal Term. 5.2. This Addendum shall automatically terminate with respect to any Carrier markets covered by an IRSA that expires or is terminated and not replaced or superseded with another intercarrier roamer service agreement between SBMS and Carrier. 5.3. SBMS may terminate this Agreement immediately upon written notice to Carrier that: (a) the ACA between SBMS and HighwayMaster has terminated; or (b) HighwayMaster has notified SBMS that the Cellular Service Agreement between Carrier and HighwayMaster has terminated. For purposes of this section, SBMS shall be entitled to rely solely on notification from HighwayMaster with respect to whether the Cellular Service Agreement between Carrier and HighwayMaster has terminated. 6. Neither Party hereto shall be liable to the other Party or any third party, including affiliates, subsidiaries or partnership interests, for indirect, incidental, consequential, reliance or special damages, including, without limitation, damages for lost profits, regardless of the form of action whether in contact, indemnify, warranty, strict liability or tort arising from or related to the performance of the duties of either Party in accordance with the terms set forth herein or the rendering of services hereunder. 7. The Parties agree that HighwayMaster is an intended third-party beneficiary of this Addendum. 2 21 8. To the extent that the provisions of the Addendum conflict with the IRSA(s), this Addendum shall control. 9. This Addendum may only be modified by written agreement of the Parties hereto.
