Information and to prevent its subsequent unauthorized use or dissemination,
including availing itself of actions for seizure and injunctive relief.  If
Distributor fails to take these steps in a timely and adequate manner, USSI may
take them in its own or Distributor's name and at Distributor's expense.

request and (ii) take no steps on its own without USSI's prior approval.

in this Agreement, Distributor will neither have nor represent itself to have
any authority to act on USSI's behalf.

laws of the State of Nebraska, U.S.A., excluding its conflict of law principles.
USSI and Distributor exclude the United Nations Convention on Contracts for the
International Sale of Goods from this Agreement and any transaction between them
that may be implemented in connection with this Agreement.

24.  ARBITRATION
     -----------

     a.  GENERAL.  Except as contemplated under Paragraph 24(d), any controversy
         -------                                                                
or claim arising out of or relating to this Agreement or the existence,
validity, breach or termination thereof, whether during or after its term, will
be finally settled by compulsory arbitration in accordance with the Commercial
Arbitration Rules and Supplementary Procedures for International Commercial
Arbitration of the American Arbitration Association ("AAA"), as modified or
supplemented under this Section 24; provided, however, that in the event of any
such controversy or claim, (i) neither party will initiate arbitration within
the first 30 days after the aggrieved party first notifies the other party of
the controversy or claim and (ii) during such 30-day period, the chief executive
officers of both parties 

                                    Page 16
<PAGE>
 
convene at least once in Phoenix, Arizona, to endeavor in good faith to amicably
resolve the controversy or claim.

     b.  PROCEEDING.  To initiate arbitration, either party will file the
         ----------                                                      
appropriate notice at the Regional Office of the AAA in Omaha, Nebraska, U.S.A.
The arbitration proceeding will take place during a period not exceeding 120
days in Omaha, Nebraska, U.S.A., and will be conducted in the English language.
The arbitration panel will consist of 3 arbitrators, one arbitrator appointed by
each party and a third neutral arbitrator appointed by the AAA. Any
communication between a party and any arbitrator will be directed to the AAA for
transmittal to the arbitrator. The parties expressly agree that the arbitrators
will be empowered to, at USSI's request, (i) issue an interim order or award
requiring Distributor to cease using the Products or Information pending the
outcome of the arbitration or (ii) grant injunctive relief.

     c.  AWARD.  The arbitral award will be the exclusive remedy of the parties
         -----                                                                 
for all claims, counterclaims, issues or accountings presented or plead to the
arbitrators.  The award will (i) be granted and paid in U.S. Dollars exclusive
of any tax, deduction or offset and (ii) include interest from the date of
breach or other violation of the Agreement until the award is fully paid,
computed at the then-prevailing LIBOR rate.  Judgment upon the arbitral award
may be entered in any court that has jurisdiction thereof.  Any additional
costs, fees or expenses incurred in enforcing the arbitral award will be charged
against the party that resists its enforcement.

     d.  LEGAL ACTIONS.  Nothing in this Section will prevent USSI from seeking
         -------------                                                         
injunctive relief against Distributor or filing legal actions for payment of
outstanding and past due debts in the courts of the Territory.

25.  ENTIRE AGREEMENT

statement of all terms, conditions and representations of the agreement between

Distributor hereby grants Customer, and Customer hereby accepts from
Distributor, an indefinite, nonexclusive and non-transferable right to use the
software products described in Section 1 below (the "Products") on the
designated hardware described in Section 2 below (the "Designated Hardware"),
subject to the terms and conditions specified below.
<PAGE>
 
                         GENERAL TERMS AND CONDITIONS
                         ----------------------------



1.  PRODUCTS.
    -------- 

"Products" means (i) the machine-readable object code version of the software
that USSI of ___________________,_________, U.S.A. ("USSI") makes available
through Distributor and described in the Product Schedule, whether embedded on
disc, tape or other media, for use on the computer platform specified in the
Product Software (the "Software"), (ii) the published user manuals and
documentation that Distributor makes generally available for the Software (the
"Documentation"), (iii) the updates or revisions of the Software or
Documentation that Distributor may offer to Customer pursuant to Section 5 (the
"Updates") and (iv) any copy of the Software, Documentation or Updates.  Nothing
in this Agreement will entitle Customer to receive the source code of the
Software or Updates, in whole or in part.

2.  DESIGNATED HARDWARE.
    ------------------- 

"Designated Hardware" means the hardware equipment specified in the Product
Schedule.  Customer may use the Products only on the Designated Hardware while
it possesses and operates the Designated Hardware. If the Designated Hardware
becomes temporarily inoperable Customer may load and use the Software and
related Updates on another of its computer hardware systems at the same location
until the Designated Hardware becomes operable, but in no event for more than 30
days. Any other use or transfer of the Software or related Updates will require
Distributor's prior approval, which may be subject to additional charges.

3.  USE.
    --- 

Customer may use the Products only in and for Customer's own internal purposes
and business operations. Customer will not permit any other person to use the
Products, whether on a time sharing, remote job entry or other multiple user
arrangement.  Customer will not install the Software or any updates on a network
or other multi-user computer system unless otherwise specified in the Product
Schedule, in which case the Designated Hardware may be used to provide database
or file services to other of Customer's computers across the network, up to the
number of concurrent users specified in the Product Schedule.  Customer may make
only one back-up archival copy of the Software and any related Update.  Customer
will reproduce all confidentiality and proprietary notices on each of these
copies and maintain an accurate record of the location of each of these copies.
Customer will not otherwise copy, translate, modify, adapt, decompile,
disassemble or reverse engineer the Products.

4.  PAYMENT.
    ------- 

Customer will pay to Distributor the Software License Fee specified in the
Product Schedule in the currency and by the date specified in the Product
Schedule. All amounts specified in the Product Schedule are exclusive of any
applicable value added, use, sales, service, property or other taxes or
contributions, which Customer will pay in addition to the amount due and
payable. Any amount not paid when due will accrue interest at the rate of ____%.
Customer will pay such interest when remitting the principal amount to
Distributor.

5.  MAINTENANCE.
    ----------- 

Distributor will provide Customer, at no additional charge with the Updates that
USSI may make generally available during the initial 12-month maintenance period
specified in the Product 

                                    Page 2
<PAGE>
 
Schedule. Customer may elect to continue receiving the said Updates for
additional 12-month periods by paying Distributor its then current maintenance
fee. The maintenance fee shall be payable annually in advance. The current
maintenance fee is specified in the Product Schedule. Customer shall install the
Updates only on the Designated Hardware. IF an Update replaces the prior version
of the Software, Customer will destroy such prior version upon installing the
Update. This Paragraph will not be interpreted to require USSI to (i) develop
and release Updates or (ii) customize the Updates to satisfy Customer's
particular requirements. The Updates will not include any new products that USSI
decides, in its sole discretion, to make generally available as a separately
priced upgrade or option.

6.  LIMITED WARRANTIES.
    ------------------ 

(a) Warranty.  Distributor warrants that (i) the Products will conform to USSI's
    --------
published specifications in effect on the date of delivery and (ii) the Products
will perform substantially as described in the accompanying Documentation after
delivery for the warranty period specified in the Product Schedule. Customer
acknowledges that (i) the Products may not satisfy all of Customer's
requirements and (ii) the use of the Products may not be uninterrupted or error-
free.  Customer further acknowledges that (i) the Software License Fee and other
charges contemplated under this Agreement are based on the limited warranty,
disclaimers and limitation of liability specified in Sections 6, 7 and 8 and
(ii) such charges would be substantially higher if any of these provisions were
unenforceable.(c)

(b)  Remedies.  In case of breach of warranty or any other duty related to the
     --------
quality of the Products, Distributor or its representative will correct or
replace any defective Product or, if not practicable, Distributor will accept
the return of the defective Product and refund to Customer (i) the amount
actually paid to Distributor for the defective Product, less depreciation based
on a 5-year straight line depreciation schedule, and (ii) a pro rata share of
any maintenance fees that Customer actually paid to Distributor for the period
that such product was not usable. Customer acknowledges that this Paragraph sets
forth Customer's exclusive remedy, and Distributor's exclusive liability, for
any breach of warranty or other duty related to the quality of the Products.

(c) Disclaimer.  EXCEPT AS EXPRESSLY PROVIDED IN THIS AGREEMENT, ALL WARRANTIES,
    ----------
CONDITIONS, REPRESENTATIONS, INDEMNITIES AND GUARANTEES WITH RESPECT TO THE
PRODUCTS, WHETHER EXPRESS OR IMPLIED, ARISING BY LAW, CUSTOM, PRIOR ORAL OR
WRITTEN STATEMENTS BY DISTRIBUTOR, ITS LICENSORS OR REPRESENTATIVES OR OTHERWISE
(INCLUDING, BUT NOT LIMITED TO ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE) ARE HEREBY OVERRIDDEN, EXCLUDED AND DISCLAIMED.

7.  INDEMNITY.
    --------- 

(a) Indemnity.  If an action is brought against Customer claiming that a Product
    ---------
infringes a patent or copyright within the jurisdiction where the Designated
Hardware is situated (the "Territory"), Distributor will defend Customer at
Distributor's expense and, subject to this Section and Section 8, pay the
damages and costs finally awarded against Distributor in the infringement
action, but only if (i) Customer notifies Distributor promptly upon learning
that the claim might be asserted, (ii) Distributor or USSI has sole control over
the defense of the claim and any negotiation for its settlement or compromise
and (iii) Customer takes no action that, in Distributor's judgment, is contrary
to Distributor's or USSI's interest.

                                    Page 3
<PAGE>
 
(b) Alternately Remedy. If a claim described in Paragraph 7(a) may be or has
    ------------------
been asserted, Customer will permit Distributor, at Distributor's option and
expense, to (i) procure the right to continue using the Product, (ii) replace or
modify the Product to eliminate the infringement while providing functionally
equivalent performance or (iii) accept the return of the Product and refund to
Customer the amount actually paid to Distributor for such Product, less
depreciation based on a 5 year straight-line depreciation schedule and a pro
rata share of any maintenance fees that Customer actually paid to Distributor
for the period that such Product was not usable.

(c) Limitation.  Distributor shall have no indemnity obligation to Customer
    ----------
under this Section if the patent or copyright infringement claim results from
(i) a correction or modification of the Product not provided by USSI, (ii) the
failure to promptly install an Update or (iii) the combination of the Product
with other non-USSI software.

8. NO CONSEQUENTIAL DAMAGES.
   ------------------------ 

UNDER NO CIRCUMSTANCES WILL DISTRIBUTOR, USSI OR THEIR LICENSORS OR
REPRESENTATIVES BE LIABLE FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL, PUNITIVE OR
INCIDENTAL DAMAGES OR LOST PROFITS, WHETHER FORESEEABLE OR UNFORESEEABLE, BASED
ON CUSTOMER'S CLAIMS OR THOSE OF ITS CUSTOMERS (INCLUDING, BUT NOT LIMITED TO,
CLAIMS FOR LOSS OF DATA, GOODWILL, USE OF MONEY OR USE OF THE PRODUCTS,
INTERRUPTION IN USE OR AVAILABILITY OF DATA, STOPPAGE OF OTHER WORK OR
IMPAIRMENT OF OTHER ASSETS), ARISING OUT OF BREACH OR FAILURE OF EXPRESS OR
IMPLIED WARRANTY, BREACH OF CONTRACT, MISREPRESENTATION, NEGLIGENCE, STRICT
LIABILITY IN TORT OR OTHERWISE, EXCEPT ONLY IN THE CASE OF DEATH OR PERSONAL
INJURY WHERE AND TO THE EXTENT THAT APPLICABLE LAW REQUIRES SUCH LIABILITY.  IN
NO EVENT WILL THE AGGREGATE LIABILITY WHICH DISTRIBUTOR, USSI OR THEIR LICENSORS
OR REPRESENTATIVES MAY INCUR IN ANY ACTION OR PROCEEDING EXCEED THE TOTAL AMOUNT
ACTUALLY PAID BY CUSTOMER FOR THE SPECIFIC PRODUCT THAT DIRECTLY CAUSED THE
DAMAGE.

9. OWNERSHIP.
   --------- 

All trademarks, service marks, patents, copyrights, trade secrets and other
proprietary rights in or related to the Products are and will remain the
exclusive property of USSI or its designees, whether or not specifically
recognized or perfected under local applicable law. Customer will not take any
action that jeopardizes USSI's or its designee's proprietary rights or acquire
any right in the Products, except the limited use rights specified in Section 4.
USSI or its designee will own all rights in any copy, translation, modification,
adaptation or derivation of the Products, including any improvement or
development thereof.  Customer will obtain, at Distributor's request, the
execution of any instrument that may be appropriate to assign these rights to
USSI or its designee or perfect these rights in USSI's or its designee's name.

10. CONFIDENTIALITY.
    --------------- 

(A) Confidentiality.  Customer acknowledges that the Products incorporate
    ---------------
confidential and proprietary information developed or acquired by or licensed to
USSI.  Customer will take all reasonable precautions necessary to safeguard the
confidentiality of the Products, including (i) those taken by Customer to
protect Customer's own confidential information and (ii) those which 

                                    Page 4
<PAGE>
 
Distributor or its authorized representative may reasonably request from time to
time. Customer will not allow the removal or defacement of any confidentiality
or proprietary notice placed on the Products. The placement of copyright notices
on these items will not constitute publication or otherwise impair their
confidential nature.

(b) Disclosure.  Customer will not disclose, in whole or in part, any item of
    ----------
the Products that has been designated as confidential to any individual, entity
or other person, except to those of Customer's employees or consultants who (i)
require access for Customer's authorized use of the Products and (ii) agree to
comply with the use and non-disclosure restrictions applicable to the Products
under this Agreement.  If requested by Distributor, Customer shall cause such
employees and consultants to execute appropriate confidentiality agreements.
Customer acknowledges that any unauthorized use or disclosure of the Products
may cause irreparable damage to USSI, its licensors and Distributor. If an
unauthorized use or disclosure occurs, Customer will immediately notify
Distributor and take, at Customer's expense, all steps which may be available to
recover the Products and to prevent their subsequent unauthorized use or
dissemination.

(c) Limitation.  Customer will have no confidentiality obligation with respect
    ----------
to any portion of the Products that (i) Customer independently developed before
receiving the Products under this Agreement, (ii) Customer lawfully obtained
from a third party under no confidentiality obligation or (iii) became available
to the public other than as a result of any act or omission by Customer or any
of Customer's employees or consultants.

11. TERMINATION.
    ----------- 

Customer may terminate this Agreement, without right to refund, by notifying
Distributor of such termination.  Distributor may terminate this Agreement, upon
reasonable notice and without judicial or administrative resolution, if Customer
or any of Customer's employees or consultants breach any term or condition
hereof.  This Agreement will terminate automatically if Customer becomes
insolvent or enters into bankruptcy, suspension of payments, moratorium,
reorganization or any other proceeding that relates to insolvency or protection
of creditor's rights.  Upon the termination of this Agreement for any reason,
all rights granted to Customer hereunder will cease, and Customer will promptly
(i) purge the Software and any related Updates from the Designated Hardware and
all of Customer's other computer systems, storage media and other files, (ii)
destroy the Products and all copies thereof and (iii) deliver to Distributor an
affidavit which certifies that Customer has complied with these termination
obligations.  The provisions of Sections 8, 9, 10, and 12 will survive the
termination of this Agreement.

12. U.S. EXPORT RESTRICTIONS.
    ------------------------ 

Customer acknowledges that the Products and all related technical information,
documents and materials are subject to export controls under the U.S. Export
Administration Regulations.  Customer may not re-export or divert the Products
or any related technical information, document or material, or direct products
thereof, to any of the following countries or to any resident thereof, unless
Customer has obtained an appropriate authorization from USSI and the U.S.
Commerce Department and any relevant local governmental authority:  Afghanistan,
Albania, Bulgaria, Cambodia, Cuba, Czech and Slovak Federative Republic, Iran,

<PAGE>
 
13. INSPECTION.
    ---------- 

During the term of this Agreement, Distributor or its representative may, upon
prior notice to Customer, inspect the files, computer processors, equipment and
facilities of Customer during normal working hours to verify Customer's
compliance with this Agreement.  While conducting such inspection, Distributor
or its representative will be entitled to copy any item that Customer may
possess in violation of this Agreement.

14. USSI'S RIGHTS.
    ------------- 

Customer acknowledges that the provisions of this Agreement are intended to
inure to the benefit of USSI. If Customer breaches any of these provisions, USSI
will be entitled to enforce this Agreement directly against Customer, whether in
Distributor's or USSI's name.  Customer further acknowledges that Distributor
executes this Agreement as principal on its own behalf and, exclusively to
accept or otherwise perfect USSI's rights against Customer, as agent on behalf
of USSI.

15. ASSIGNMENT.
    ---------- 

Customer shall not assign, delegate or otherwise transfer this Agreement or any
of its rights or obligations hereunder without Distributor's prior approval.  If
Distributor ceases to be USSI's authorized distributor for any reason, this
Agreement may be assigned to USSI or its designee effective immediately upon
notice from USSI, and Customer consents to such assignment in advance.

16. MISCELLANEOUS.
    ------------- 

All notices or approvals required or permitted under this Agreement must be
given in writing.  Any waiver or modification of this Agreement will not be
effective unless executed in writing and signed by Distributor and approved by

Agreement will be governed and interpreted in accordance with the laws of the
territory (country).  If any provision of this Agreement is held to be
unenforceable, in whole or in part, such holding will not affect the validity of
the other provisions of this Agreement, unless Distributor in good faith deems
the unenforceable provision to be essential, in which case Distributor may
terminate this Agreement effective immediately upon notice to Customer.  This
Agreement constitutes the complete and entire statement of all conditions and
representations of the agreement between Distributor and Customer with respect
to its subject matter and supersedes all prior writings or understandings.

                           USSI TRAVEL EXPENSE POLICY
                           --------------------------



Here is an outline of USSI's employee travel expense policy. I've broken this
down into 5 categories, Air Travel, Lodging, Ground Transportation, Meals, and
Incidental Travel Expenses.


LODGING
-------

Hotel accommodations are coordinated through the company's travel agent. The
travel agent is responsible for selecting rooms based on circumstances and
corporate programs in place. Hotels are to be moderately priced, and afford
acceptable degrees of comfort, convenience, and security.

Suggestions by ULTRADATA on a hotel that they would prefer for us to use would
be welcome.


AIR TRAVEL
----------

Our travel agent is responsible for booking the lowest priced fare for all
travel. Exceptions to taking the lowest priced fare must be authorized by the
employee's manager.

Air travel is booked as far in advance as possible to take advantage of discount
fares.

Only Coach Class reservations are permitted.


GROUND TRANSPORTATION
---------------------

Car rentals are used when the efficient conduct of business precludes less
expensive means of transportation. Employees traveling in groups should share
rental cars to minimize expense.

Car rentals are coordinated through our travel agent. Cars are selected based on
circumstances and corporate programs that impact the cost. The size of cars are
limited to compact or medium unless group size requires a larger vehicle.


MEALS
-----

Meals and incidental costs incurred by employees while traveling are reimbursed
in the form of a Per Diem allowance.
<PAGE>
 
The per diem covers breakfast, lunch, dinner, tips, cleaning, laundry, and other
miscellaneous items.

Per Diem for the Oakland California area is currently $33.00


INCIDENTAL TRAVEL EXPENSES
--------------------------

Other certain incidental  but reasonable and necessary travel expenses that can
be billed are as follows.

1 personal phone call per day of reasonable length of time.

Laundry charges if the employee's trip extends for more than one week.

Tips for hotel and airline porters at $1.00 per bag.

USSI STANDARD MAINTENANCE SERVICES


     CUSTOMER HOTLINE



     Clients are provided access to a 24 hour, 7 day a week telephone assistance
     service.  Hotline staff work with callers to resolve performance problems
     or answer questions.  Calls are logged, and tracked until resolved.


     CUSTOMER SUPPORT MANAGER

     An Account Manager is assigned to each customer.  Account Managers channel
     information between the customer and USSI.  The individual maintains a
     continuous formal record of all information exchanged with, and services
     delivered to clients.  Your Account Manager will help you with a wide range
     of tasks:

       -  Response to general inquiries

       -  Document modification requirements

       -  Represent modification requirements to designers and track development
     
       -  Interface with Hotline agents to resolve problems and answer questions

       -  Package and deliver software

       -  Announce and schedule training and respond to special requests for
          education classes

       -  Provide and discuss enhancement/new product details

       -  Coordinate onsite services of technical staff

     A complete description of activities and responsibilities is provided in
     the next section - Customer Support Services.


     PUBLICATIONS

     Maintenance customers receive regular updates of applicable system
     documentation.  In addition, we distribute  product announcements,
     enhancement announcements and other formal communiques.
<PAGE>
 
     MAINTENANCE RELEASES



     As part of our standard maintenance, USSI provides timely updates of
     current software to provide regulatory and product changes.  These releases
     are provided with sufficient lead time to meet industry and regulatory
     requirements.  Installation instructions are included.


     UPGRADES/ENHANCEMENTS

     In response to user groups and competitive forces, USSI regularly makes
     improvements to individual products.  These enhancements or upgrades come
     in the form of additional features and options that improve operations or
     expand your markets. These upgrades are delivered in the same manner as
     maintenance releases and may be combined with maintenance releases to
     simplify implementation.


     MAINTENANCE AND CUSTOM SOFTWARE MODIFICATIONS

     Custom Software Modifications effect the compatibility of Maintenance and
     Upgrade releases.  The existence of customer-specific programs does not
     preclude maintenance and upgrade releases.  However, for these special
     situations, installation of maintenance and upgrade releases becomes a
     custom process.  USSI designs customized installation programs for the re-
     integration of Custom Software Modifications.  This service is supplied
     routinely to Extended Maintenance customers (explained later in this
     document) or selectively on a contractual basis each time a release is made
     available.
<PAGE>
 
SECTION 2
--------------------------------------------------------------------------------
CUSTOMER HOTLINE SERVICE

USSI provides maintenance customers with 24 hour support to resolve software
problems and respond to questions about any aspect of products or services.
Support is supplied by the Customer Hotline.

Agents at the Hotline work with clients to identify and document problems or
questions and formulate appropriate action plans.  Clients should select a
representative who will act as the primary liaison for Hotline contact.  Fast
problem resolution is the goal of our service.  To accomplish this we rely on
accurate communications from those seeking solutions.  Guidelines for
registering inquiries include:

     -  Identify yourself, organization and software products used

     -  Identify the version of the application software indicating a problem.
     -  Describe the problem in detail.
     -  A description should include:

        -  accurate references to screens, reports, symptoms

        -  specific step-by-step process description so that our technicians can
           replicate the condition, when necessary for resolving problems

        -  information about the impact of the problem so that a priority can be
           assigned.

Each record is assigned a Customer Reference Number and a priority.  The agent
then develops an action plan, which may include referral of the problem or
question to technicians, product managers or others.

Priorities have been developed so that we can identify the seriousness of an
inquiry and focus resources on problems that jeopardize clients' operations.  If
there is contention for limited technical resources, treatment of high priority
problems supersedes treatment of low priority inquiries.

Priority is determined through dialog between the hotline staff and the client
caller.  Four priority definitions are employed by our staff:


     CRITICAL (PRIORITY 1)

     The customer's production system or network is down or network control is
     in immediate jeopardy of going down.  Either online transaction processing
     or essential batch processing activities have ceased or are in eminent
     danger of stopping.
<PAGE>
 
USSI assigns resources immediately and makes efforts to remove the symptom.
Technicians develop and implement plans intended to restart systems and return
service to users.  Once service is returned, the problem may be reassigned to a
lower priority for careful research, identification of cause and correction of
conditions that may have lead to failure.

     SERIOUS (PRIORITY 2)

     The customer's production system is not down, but there is an impact to the
     system or networks.  The customer diagnosis is that should the problem
     persist, loss of online transaction processing or loss of critical batch
     operations will occur.  Included in this category are problems that
     obstruct certification or Go-live.

     USSI staff work to resolve symptoms and problems so that project plans are
     not subverted.

     INCONVENIENCE (PRIORITY 3)

     The problem is an inconvenience to the customer on either the production or
     test system.  There is no loss of service to online transaction processing.
     There is no interruption of critical batch processes.  Serious symptoms can
     be averted through operator intervention and special procedures prescribed
     by USSI technicians.

     INFORMATIONAL (PRIORITY 4)

     The problem is an operator inconvenience, or the customer has asked for
     information.  There is no serious impact on the end user of the system.
     The symptom or problem can be avoided by application of procedural steps
     executed by the operators.  There is no apparent danger of losing control
     of the system/network or data.

Customers who wish to check the status of a problem registered at the Hotline
may contact the Hotline operators or their own Account Manager. The customer
should reference the tracking number.

Each client's Account Manager monitors problems that client submitted to the
Hotline.  Regularly, the Account Manager reports to the client's primary contact
the status of all outstanding and recently resolved problems.

PRODUCT SUPPORT SERVICES POLICIES

1.   USSI TRANS24 products are classified into product support categories A-D.
     USSI Product Management establishes these product support levels to best
     meet the on-going needs of the  TRANS24 customers.  Classification of a
