ACCEPTANCE
----------

All Goods shall be received by Buyer subject to Buyer's inspection and right of

Buyer may reject such Goods by notifying Supplier in writing of such rejection
and requesting a Returned Material Authorization ("RMA") number; provided, that
such written notification and request for an RMA number must be received by
Supplier during the Inspection Period. Within ten (10) days of receipt of the
RMA number, Buyer shall return the defective Goods to Supplier, insured and with
transportation prepaid, with a written description of the defect. Supplier will
at its option replace the returned Goods or issue Buyer a credit for the
returned Goods at no charge to Buyer (including return transportation and
related insurance costs) if Supplier confirms the defect. Goods not rejected
during the Inspection Period will be deemed accepted upon the expiration of the
Inspection Period.

ASSIGNMENT
----------

Neither party shall assign any right or obligation under this Agreement without
the other party's prior written consent; provided, however, that either party
shall have the right to assign its rights, obligations and privileges hereunder
to a merger partner, successor in business, or acquirer of all or substantially
all of such party's stock (or equivalent equity securities), business, or assets
without obtaining the other party's consent to such assignment. Any other
attempted assignment shall be void, except that either party may assign moneys
due or to become due to it, provided that (a) the assigning party gives the
other party at least thirty (30) days prior written notice of such assignment
and (b) such assignment does not impose upon the other party obligation to the
assignee other than the payment of such moneys.

Notwithstanding the foregoing, Buyer may assign this Agreement, in whole or in
part, to any of its Affiliates who agree in writing to be bound by the terms and
conditions of this Agreement. Upon such assignment and assumption of liability.
Thereto by the assignee the assignor shall be discharged of any liability under

and assigns.

Supplier represents and warrants to Buyer that it is a corporation duly
organized; validly existing and in good standing under the laws of the State of
California.  Supplier represents and warrants to Buyer that it has all requisite
power and authority and all material licenses, permits and other authorizations
necessary to carry, on its business as now conducted. Supplier represents and
warrants to Buyer that it has all requisite power and authority to execute,
deliver and perform this Agreement and the other agreements contemplated hereby
and to perform its obligations hereunder and thereunder. The execution, delivery
and performance by Supplier of this Agreement have been duly and validly

Supplier, its Board of Directors or its shareholders is necessary to authorize
the execution, delivery or performance by Supplier of this Agreement.

---------------

Supplier shall maintain, at no additional charge to Buyer, in accordance with
generally accepted accounting principles, complete and accurate records related
to amounts billed to and payments made by Buyer hereunder. Supplier shall
provide Buyer supporting documentation concerning any alleged violation by
Supplier of the terms of this Agreement or concerning any disputed invoice or
payment within thirty (30) days after Buyer notifies Supplier of a dispute or,

amounts in dispute; provided, that Buyer provides Supplier reasonable advance
notice of such audit. Payments made under this
<PAGE>

Supplier shall retain such records for a period of three (3) years from the
expiration of this Agreement or such length of time as may be required by any
federal, state or local law, ordinance or regulation, whichever is longer.

CHANGES TO GOODS
----------------

Supplier may not make changes to the Goods or modify the drawings and
specifications relating thereto, or substitute products of a later design to
fill a Purchase Order, without Buyer's consent. As conditions to such consent,
such change, under normal and proper use, shall not affect the price, operation,
reliability or life of the Goods or the interchangeability of the Goods with
other goods, and Supplier shall notify Buyer in writing thereof not less than
ninety (90) days prior to the planned change. In the event Buyer and Supplier

without penalty or obligation of any kind.

Notwithstanding any notice requirement above to the contrary, in the event an
extremely unsatisfactory condition, including, by way of example and not of
limitation, a safety or fire hazard, requires immediate action, Supplier shall
immediately notify Buyer. For a period of five (5) years after the Delivery Date
of the Goods affected thereby ("Hazard Period"), as Buyer's sole remedy and
Supplier's exclusive liability, Supplier shall use commercially reasonable
efforts to replace or modify, at no charge to Buyer, all such Goods, including
spare parts, in Buyer's possession. The Buyer will return such Goods by
notifying Supplier in writing and requesting an RMA number; provided, that such
written notification and request for an RMA number must be received by Supplier
during the Hazard Period. Within ten (10) days of receipt of the RMA number,
Buyer shall return the defective units to Supplier, insured and with
transportation charges prepaid, with a written description of the defect. The
limited remedies set forth in this Section shall not apply if (i) the Goods have
been altered or modified, (ii) the Goods have been damaged by reason of
negligence not attributable to Supplier, or subjected by Buyer to computer or
electrical malfunction, or (iii) the Goods have been used, adjusted, installed,
maintained, or operated other than in accordance with instructions furnished by
Supplier, or with an application or in an environment other than that intended
or recommended by Supplier.

Any information, including but not limited to, specifications, drawings,
computer programs, technical or business information or other data in whatever
form (hereinafter "Information"), furnished by either party to the other,
whether in writing, orally or visually, under or in contemplation of this
Agreement or to which such party has access through its performance hereunder
shall be considered confidential and shall be subject to the following:

     (a)       The receiving party shall restrict disclosure of the Information
          to the receiving party's employees with a "need to know" (i.e.,
          employees that require the Information to perform their
          responsibilities in connection with this Agreement or a Purchase
          Order) and shall not disclose it to any other person or entity
          without the prior written consent of the disclosing party;

     (b)       The receiving party shall use the Information only for purposes
          of performing under this Agreement;

     (c)       The receiving party, shall advise those employees who access the
          Information of their obligations with respect thereto;

     (d)       The receiving party shall copy the Information only as necessary
          for those employees who are entitled to receive it and shall ensure
          that all confidentiality notices are reproduced in full on such
          copies; and

     (e)       The receiving party shall return all copies of such Information
          to the disclosing party at the disclosing party's request.

The receiving party recognizes and agrees that the unauthorized use or
disclosure of the Information would cause irreparable harm to the disclosing
party for which it would have no adequate remedy at law, and that an actual or
contemplated breach of this Section shall entitle the disclosing party to obtain
immediate injunctive relief prohibiting such breach, in addition to any other
rights available to it. The obligations herein contained shall expressly survive
the termination or expiration of this Agreement.

The Information shall not be considered confidential and shall not be subject to
the foregoing if the receiving party can demonstrate that the Information:
<PAGE>

     (a)       Is or becomes available to the public through no breach of this
          Agreement or a Purchase Order;

     (b)       Was previously known by the receiving party without any
          obligation to hold it in confidence;

     (c)       Is received from a third party free to disclose such Information
          without restriction;

     (d)       Is independently developed by the receiving party without the use
          of the disclosing party's Information;

     (e)       Is approved for release by written authorization of the
          disclosing party, but only to the extent of such authorization;

          extent and for purposes of such required disclosure; or

     (g)       Is disclosed in response to a valid order of a court or lawful
          request of a governmental agency, but only to the extent of and for
          the purposes of such order or request, provided that the receiving
          party first notifies the disclosing party of the order or request ten
          (10) days prior to disclosure and permits the disclosing party to seek
          an appropriate protective order.

DEFAULT
-------

If either party fails to perform or observe, in any substantial way, any
material term or condition of this Agreement or a Purchase Order, such action
shall constitute a material breach of this Agreement. If the breaching party
fails to remedy or to undertake reasonable steps to remedy such material breach
within fifteen (15) days after receipt of written notice of the breach from the
non-breaching party, the non-breaching party may, without further notice, cancel
the then-remaining balance of this Agreement and/or any Purchase Order, as
applicable, without any further obligation thereunder whatsoever except as to
payment for Goods already received and accepted by Buyer. In the event the
Supplier is the party in default and the parties established a commitment,
purchase level or discount program, the quantity covered by such canceled
Purchase Order(s) shall be deducted from such commitment, purchase level or
volume required for discount entitlement. The rights provided to the non-
breaching party under this Section are not intended to constitute an election
of remedies, and, except as provided otherwise in this Agreement or the subject
Purchase Order, the non-breaching party shall be entitled to any additional
rights and remedies available to it at law or in equity.

Unless otherwise agreed by the parties in writing, this Agreement will terminate
upon the termination of the Wireless Network Services Agreement of even date
herewith between the Buyer and Supplier.
<PAGE>

DELAYS
------

Time is of the essence in Supplier's performance of its obligations under
Agreement. If Supplier has knowledge that anything prevents or threatens to
prevent timely performance under this Agreement, Supplier shall immediately
notify Buyer thereof, provided such notification shall not relieve Supplier of
the requirement set forth in the preceding sentence.

DELIVERY
--------

Supplier shall deliver all Goods on the delivery date ("Delivery Date") and to
the site specified on the applicable purchase order and on Supplier's
acknowledgment thereof. Buyer may elect to advance or delay such Delivery Date
provided that Supplier has been given no less than ten (10) days written notice,
prior to the Delivery Date of such change.

ENTIRE AGREEMENT
----------------

The terms in this Agreement and the attachment(s) and specification(s) referred
to herein, which are incorporated herein by this reference, constitute the
entire agreement between the parties with respect to the subject matter hereof,
superseding all prior understandings and communications, oral or written. The
Parties acknowledge that this Agreement has been mutually negotiated. In
addition, neither party shall be bound by any terms additional to or different
from those in this Agreement that may appear subsequently in quotations,

by governmental regulations, civil or military authorities, acts of God, the
public enemy or other causes which are beyond the reasonable control of the
party unable to perform (hereinafter "Force Majeure"). If a Force Majeure
occurs, the party delayed or unable to perform shall give immediate notice to
the other party. In the event Supplier is the party delayed or unable to
perform, Buyer may elect: (a) to terminate any affected Purchase Order relating
to Goods not already delivered without liability to Supplier, or (b) to suspend
performance under the affected Purchase Order for the duration of the Force

<PAGE>

INFRINGEMENT
------------

Supplier shall defend, indemnify and hold harmless Buyer and its Affiliates,

receipt of any services) provided under this Agreement. Buyer shall promptly
notify Supplier of any claim of infringement, violation or misappropriation for
which Supplier is responsible and shall cooperate with Supplier to facilitate
the defense or settlement of such claim. Supplier or Supplier's attorney(s)
shall keep Buyer reasonably apprised of the continuing status of the claim,
including any lawsuit resulting therefrom, and shall permit Buyer, upon Buyer's
written request, to participate in the defense or settlement of such claim.

If use of the Goods shall be prevented or appears likely to be prevented by
court order or settlement resulting from any such claim, Supplier shall, at its
expense, either: (a) by license or release from claim of violation, infringement
or misappropriation, procure for Buyer and/or the Affiliates the right to
continue using the Goods; or (b) modify Goods so that they are functionally
equivalent to the original Goods but are no longer subject to a claim of
violation, infringement or misappropriation; or (c) remove such Goods from the
premises of Buyer and/or the Affiliates and replace same with equally suitable
goods free from claim of infringement or misappropriation; or (d) terminate this

foregoing insurance. Supplier's policy shall be endorsed to name __________
_______________________ and its corporate Affiliates as additional insureds
and state: "____________________________________ is to be notified in writing
at least sixty (60) days prior to cancellation of or any material change in this
policy." At Buyer's request, Supplier shall furnish a copy of the endorsement
and certificates evidencing the foregoing insurance coverage prior to

terms and conditions of this Agreement; provided, that Buyer shall not be
responsible for procuring such agreement of the assignee or sub-licensee.

No other licenses, express or implied, under any patents, trademarks, copyrights
or other proprietary rights are granted by Buyer to Supplier or by Supplier to
Buyer under this Agreement.

LIMITATION ON LIABILITY
-----------------------

In no event shall either party be liable to the other party for any lost profits
or indirect, incidental, special or consequential damages, regardless of whether
or not a party has been advised of the possibility of such damages. The
foregoing notwithstanding, nothing in this section will limit a party's
obligations to indemnify fully the other under the sections of this Agreement
entitled "Indemnity" and "Infringement" for actions brought by third parties,

price to such enterprises. Upon request, Supplier shall furnish appropriate
information about its efforts to achieve this goal, including the identities of
such enterprises and amounts involved.

Supplier warrants that the prices for Goods provided to Buyer under this
Agreement and the terms and conditions of this Agreement are not and shall not
be less favorable than the prices and/or terms and conditions extended to any of
Supplier's other customers generally similarly situated to Buyer with respect to
the same or like goods. In the event Supplier offers, during the term of this
Agreement, lower prices and/or more favorable terms and conditions to any such
customer with respect to the same or like goods than are offered to Buyer,
Supplier shall, retroactive to the date Supplier offered more favorable prices,
terms or conditions to any other customer, reduce the prices hereof
correspondingly and/or shall extend such terms and conditions to Buyer. Any
amounts charged to Buyer in excess of prices charged by Supplier to any other
customer for similar Goods or related services shall promptly be refunded or
credited to Buyer by Supplier.

right to contract with other parties for the procurement of comparable goods.

addition to any other remedies available at law or in equity, except as
otherwise expressly limited or excluded by this Agreement.

SEVERABILITY
------------

achieve, and the remaining provisions of this Agreement shall continue in full
force and effect.

SHIPPING
--------

All Goods shall be packed, marked and shipped by Supplier, at no additional
charge, in containers which are suitable for prevention of damage under normal
handling during loading/unloading, shipping and storage and in accordance with
the requirements of the carrier and the commercially reasonable specifications
of Buyer. Supplier shall ship the Goods in the quantities and at the times
specified by Buyer in accordance with the routing instructions given by Buyer
and accepted by the Supplier. Supplier shall combine all shipments made on the
same day to the same destination and shall mark the shipping label with the
destination exactly as shown in the corresponding Purchase Order. The Purchase

SPECIFICATIONS FOR GOODS/WARRANTY
---------------------------------

The Supplier warrants to Buyer that the Goods shall perform in accordance with
the specifications set forth in Attachment C hereto for a period of (i) twelve
(12) months after the Goods are first used or (ii) eighteen months after the
Deliver Date, whichever period is shorter in duration (the "Warranty Period").
The Buyer will have the right to emend the Warranty Period
<PAGE>

for an additional two (2) years by paying the fee, for each unit purchased
hereunder, set forth on Attachment A hereto. In addition, Supplier warrants that
any version of the Software shall properly perform Year 2000 Processing. "Year
2000 Processing" means processing by the Software, which is dependent upon usage
of calendar dates, including dates on or after January 1, 2000. Year 2000
Processing includes both software owned by Supplier and third party software
provided by Supplier that manages and/or manipulates data involving dates,
including single century formulas and multi-century formulas. Correct or proper
Year 2000 Processing means that the Software will not cause an abnormally ending
dating scenario within the application or result in incorrect values generated
involving such dates.

Except for breach of the Year 2000 Processing warranty, which is addressed in
the Section entitled Year 2000 Capability, if buyer notifies Supplier of any
breach of the warranty set forth in this Section during the Warranty Period (if
applicable), and if Supplier, which shall act reasonably and in good faith in
its inspection of all returned Goods, confirms such defect, Supplier's exclusive
liability, and the exclusive remedy of Buyer shall be, at Supplier's
commercially reasonable discretion, repair or replacement of the Goods at no
cost to Buyer. The Buyer may reject such Goods by notifying Supplier in waiting
of such rejection and requesting an RMA number; provided, that such written
notification and request for an RMA number must be received by Supplier during
the Warranty Period (if applicable). Within ten (10) days of receipt of the RMA
number, Buyer shall return the defective Goods to Supplier, insured and with
transportation prepaid, with a written description of the defect. The limited
warranties set forth in this Section shall not apply if (i) the Goods have been
materially altered or modified, (ii) the Goods have been subjected to
negligence by Buyer, computer or electrical malfunction, or (iii) the Goods have
been used, adjusted, installed, maintained, or operated other than in accordance
with instructions furnished by Supplier, or with an application or in an
environment other than that recommended by Supplier.

EXCEPT AS EXPRESSLY PROVIDED IN THIS SECTION, SUPPLIER PROVIDES NO WARRANTY,
EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, AND SPECIFICALLY DISCLAIMS ANY
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, WITH RESPECT TO
ALL MATERIALS AND SERVICES PROVIDED TO BUYER.

SURVIVAL OF OBLIGATIONS
-----------------------

The parties' obligations under this Agreement which by their nature are intended
to continue beyond the termination or expiration of this Agreement (including
without limitation all payment obligations incurred prior to such termination or
expiration) shall survive the termination or expiration of this Agreement.

SUSPENSION OF PERFORMANCE
-------------------------

If bankruptcy proceedings are commenced with respect to Supplier and if this
Agreement has not been otherwise terminated, then Buyer may suspend all future
performance of this Agreement and/or any Purchase Order(s) hereunder until
Supplier assumes and provides adequate assurance of future performance or
rejects this Agreement or such Order(s) pursuant to (S)365 of the
<PAGE>

Bankruptcy Code or any successor provision. Any such suspension of further
performance by Buyer pending Supplier's assumption or rejection will not be a
breach of this Agreement and/or any Purchase Order(s) and will not affect
Buyer's right to pursue or enforce any of its rights under this Agreement or
such Order(s) or otherwise.

TAXES
-----

Federal manufacturers or retailers excise taxes, and state and local sales or
use taxes, when applicable, shall be billed as separate items on Supplier's

TERMINATION
-----------

Buyer may at any time and for any or no reason terminate this Agreement and/or
any Purchase Order(s), in whole or in part, by giving sixty (60) days written
notice to Supplier. Buyer's liability, to Supplier shall be limited to payment
for Goods which are ordered by Buyer prior to the effective date of termination
of this Agreement.

YEAR 2000 CAPABILITY
--------------------

Supplier warrants that any version of the Software shall properly perform Year
2000 Processing. In the event of a breach of this warranty, Supplier agrees to
promptly remedy such breach at no additional charge to Ameritech by: (i)
correcting the version of the Software currently used by Ameritech so as to make
it capable of correctly performing Year 2000 Processing; (ii) providing
replacement Software for the Software which is equivalent in function to the
Software and which correctly performs Year 2000 Processing. If, after using best
efforts Supplier is unable to accomplish either of the foregoing options within
ninety (90) days of Buyer's notification to Supplier of any failure of the
Software to correctly perform Year 2000 Processing, Supplier shall indemnify and
hold Buyer harmless from and against any and all liability, loss, or expense
awarded by final judgement against Buyer arising from any third party claims
which alleges damages to the Software. Notwithstanding anything to the contrary
set forth in this agreement, Supplier's breach of this warranty, shall not be
subject to any provisions regarding limitations of Supplier's liability set
forth in this Agreement.

15.5    Non-Waiver. No term or provision hereof shall be deemed waived or any
breach excused, unless such waiver or consent shall be in writing and signed by
the party claimed by the other to have waived or consented. Any consent by any
party, to, or waiver of, a breach by the other, whether express or implied,
shall not constitute a consent to, waiver of, or excuse for any other different
or subsequent breach.

found to be illegal or unenforceable, then notwithstanding such illegality, or
unenforceability, this Agreement shall remain in full force and effect and such

not impose upon the other party obligations to the assignee other than the
payment of such moneys. Notwithstanding the foregoing, Buyer may assign this
Agreement, in whole or in part, to any of its Affiliates who agree in writing to
be bound by the terms and conditions of this Agreement. Upon such assignment and

of any liability under this Agreement. Without limiting the generality of the
foregoing, this Agreement shall be binding upon and shall inure to the benefit
of the parties' respective successors and assigns.

provide the on-call technician with the customer name and phone number via
alpha-numeric page or the on-call technician will call into the answering
service to retrieve it. The on-call technician will then provide a return phone
call to the End User within two hours that the End User placed the call to the
answering service.
<PAGE>

     .    Problem Resolution and Escalation Procedures. @Road will perform the
          --------------------------------------------
following procedures to resolve support problems. The category of the problem
reported, as determined by the End User, will determine the escalation procedure
used for resolution.

          - Category l - End User reports an unusual abort or shutdown but is
       able to restart; End User requests a feature or change to existing
       operation - service for the End User remains in operation.

          - Category 2 - End User reports one or more RC-10 units are not
       functioning or that access to or a feature of the @Road Server is not
       functioning properly - service for the End User is down or is
       significantly impaired.

          - Category 3 - End User reports that one or more RC-10 units are not
       functioning or that access to or a feature of the @Road Server is not
       functioning properly and L1TS determines that either all or part of the
       @Road Server is down - service for an entire customer account or all
       customer accounts is down or is significantly impaired.

Category 1. Category 1 calls will be analyzed by the @Road Technical Support
----------
Representative ("TSR") to determine if the problem is part of the capabilities
of the Application Software. The problem will be resolved following the process
described in this Description of Services. If the problem was a temporary
service stoppage, error message or feature request, the problem or feature
request will be documented and forwarded to the @Road Manager of Technical
Support. If necessary, Category 1 problem resolution work is superseded by the
existence of Category 2 or Category 3 problems until the Category 2 or 3 problem
is resolved and the End User(s) is (are) up and running.

Category 2. For all Category 2 calls, L1TS personnel will work immediately and
----------
diligently to attempt to resolve the problem within 2 hours. L1TS personnel will
continue to work during normal business hours on the problem until resolved.
Category 2 problems will be transferred to the next work shift for ongoing work
if the outage is not resolved at the close of shift. @Road will provide
reasonable and best efforts to ensure that all Category 2 issues are completely
resolved within 1 business day. Category 2 problem resolution work is superseded
by the reporting of Category 3 problems if the determination is made that the
Category 2 problem is not related to the Category 3 problem.

Category 3. Category 3 problems are treated with top priority. If L1TS detects a
----------
Category 3 problem, they are instructed to immediately notify all other on-shift
L1TS personnel including the L1TS manager on duty. If the problem has not been
resolved within 30 minutes, the Manager of Technical Support ("MTS") for @Road
will be contacted regardless of the time of day. If not available, progressively
higher levels of management will be contacted. All work by any technical support
person will be suspended and all available resources will be committed to the
problem working around the clock until resolved. @Road will provide reasonable
and best efforts to ensure that all Category 3 issues are completely resolved
within 1 day.

     .    Scheduled Maintenance and Upgrade Procedures. Network, software and
          --------------------------------------------
hardware components of the VLS may require scheduled maintenance to, among other
reasons, improve performance, add features or maintain a current and supportable
infrastructure. @Road and Ameritech will use the following procedure for
scheduling maintenance downtime and for putting new software releases into
service.

     Step 1 -- @Road will determine that some combination of hardware, software
     or network components must be scheduled for maintenance or replacement. If
     @Road determines the maintenance can be performed without material or
     visible affect on End Users and thus End Users will incur no downtime from
     the upgrade, @Road will proceed with the upgrade at its discretion. If
     @Road determines that the maintenance will have a material or visible
     affect on End Users including, but not limited to, new features or changes
     to End User operation or incur End User downtime, the maintenance procedure
     will move to Step 2.

     Step 2 -- @Road will send a written notice to Ameritech outlining the
     reason for the upcoming scheduled maintenance ("Maintenance Notice"). If
     the maintenance work will include new features visible to End Users or
     changes to End User operation, @Road will outline the features of the
     upgrade including, if known, any potential problems which may be
     encountered during or after the upgrade in the Maintenance Notice. Within
     the Maintenance Notice, @Road will provide information for Ameritech to
     access a test server running the upgraded software. From the time of the
     Maintenance Notice, Ameritech has 30 calendar days to perform any testing
     of the upgrade. @Road L1TS will be available to Ameritech by telephone or
     email to review test results and discuss test progress. At the earliest
     possible time, but no longer than 30 days from the date of the Maintenance
     Notice, Ameritech will inform @Road in waiting of the acceptance or
     rejection of the upgrade. If the upgrade is rejected, Ameritech will
     document those problems or features which led to the rejection. If the
     upgrade is accepted, the process will move to Step 3. If no response is
     received, @Road will consider the upgrade accepted.

     Step 3 -- @Road will inform Ameritech in writing of the scheduled
     maintenance downtime ("Downtime Notice"). In the Downtime Notice, @Road
     will specify the time and date of the maintenance where the date is no less
     than 10 calendar days from the date of issue of the Downtime Notice. In the
     Downtime Notice, @Road will specify the period of time the service will be
     down. This specified period will be considered Excused Downtime.

     Ameritech may request a change to the date, time or period by responding in
     writing within 5 calendar days from the date of the Downtime Notice. If
     Ameritech requests a rescheduling of the maintenance, @Road and Ameritech
     will determine a mutually acceptable time, date and period. @Road will then
     issue a Revised Downtime Notice and proceed with the maintenance at the
     specified time.
<PAGE>

 .    VLS Sales Training. @Road will provide one (1) day of VLS sales training
     ------------------
at no additional cost to Ameritech sales and technical support personnel for
each Ameritech market which offers the Services hereunder. Thereafter, @Road
will provide additional reasonable training to Ameritech, provided that
Ameritech reimburses @Road for all reasonable travel, lodging, and meal expenses
@Road incurs in connection with providing such training.

 .    Facilities and Personnel. @Road will provide a full time, dedicated Sales
     ------------------------
Support Representative ("SSR") to Ameritech for the purpose of training the
Ameritech sales force on an as-needed basis and assisting with customer sales
activity, at no additional cost to Ameritech. The @Road SSR will provide the
sales training at locations provided by Ameritech.

 .    Covered Markets. @Road will provide training in the metropolitan areas of
     ---------------
all of Ameritech's CDPD coverage areas.

 .    Scheduling. Ameritech and @Road will work together to schedule training
     ----------
times that are mutually acceptable.
