property contained in any Software, documentation or Proprietary Information.

from Customer's facility at any time.

Customer or (b) has been relocated.

11.6  All system components and peripherals which are located at the same site
and interconnected with Unisys signal and power cables or their equivalent and

13.2  Unisys may assign, reassign and substitute personnel at any time and may

EXPRESS OR IMPLIED, BY OPERATION OF LAW OR OTHERWISE.  UNISYS DISCLAIMS THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE AS TO
BOTH UNISYS AND NON-UNISYS PRODUCTS.  UNISYS WARRANTIES EXTEND SOLELY TO
CUSTOMER.

14.2  Maintenance Warranty and Disclaimers

Unisys warrants that the equipment will be maintained in good working order
provided that it is continuously subject to Unisys Equipment Maintenance
Services and under normal use.  Unisys sole and exclusive obligations under this
warranty will be to repair such equipment.  Maintenance services do no cover
repair or damage attributable to (i) non-Unisys products and services, (ii)
accidents, misuse, negligence or failure of Customer to follow instructions for
proper use, care and cleaning of equipment, (iii) external factors (e.g. failure
or fluctuation of electrical power or air conditioning), or (iv) failure by
Customer to comply with Unisys environmental specifications.

14.3  Software Warranty and Disclaimers

(a)  Each item of Software with the designation "W" on Schedule B is, in its
unaltered form, warranted for 90 days from its Installation Date to conform
substantially to the then current published functional specifications, provided
such Software is used in a manner consistent with any applicable Unisys minimum
equipment and Software configuration specifications.  Unisys will satisfy this
warranty if it makes reasonable efforts to correct such errors reflecting
significant deviations from the functional specifications as are reported by
Customer to Unisys during such warranty period.

(b)  Because not all errors in Software can or need be corrected, Unisys does
not warrant that all Software defects will be corrected.  Similarly, Unisys does
not warrant that the functions contained in the Software will meet Customer's
requirements or that the Software will operate in combinations selected for use
by Customer.

(c)  All other Software delivered by Unisys, including non-Unisys Software, is
licensed "AS IS".  In the case of non-Unisys Software, Customer agrees to look
solely to the warranties and remedies, if any, provided by the Unisys licensor
or vendor.

15.  ALTERATIONS AND ATTACHMENTS

maintain, support or correct altered Products, Unisys may impose additional
charges.

degradation of performance of Products, supplies or maintenance support

15.3  Unisys warranties will not apply if attachment of non-Unisys equipment or
alteration of Products directly or indirectly results in any malfunction,

equipment, as well as modifications to Software.  "Attachments" includes, but is
not limited to, any non-Unisys equipment, components or devices which are
connected to Unisys Products.

16.2  In no event will Unisys be liable for (a) any incidental, indirect,

which may be of interest to Customer for use in conjunction with the Products.

will have sole responsibility for determining suitability for use of third-party
products and services.  Unisys has no liability with respect to claims relating
to or arising from use of  third-party products and services.

17.  PATENT, COPYRIGHT AND TRADE SECRET INDEMNIFICATION FOR SOFTWARE

17.1  Unisys, at its own expense, will defend and indemnify Customer against
claims that Unisys Software furnished under this Agreement infringes a United
States patent or copyright or misappropriates trade secrets protected under
United States law, provided Customer (a) gives Unisys prompt written notice of
such claims pursuant to Section 19, (b) permits Unisys to defend or settle the
claims, and (c) provides all reasonable assistance to Unisys in defending or
settling the claims.

17.2  As to any Software which is or, in the opinion of Unisys, may become
subject to a claim of infringement or misappropriation, Unisys may elect to (a)
obtain the right of continued use of such Software for Customer or (b) replace
or modify such Software to avoid such claim.  If neither alternative is
available on commercially reasonable terms, then, at the request of Unisys,
Customer will discontinue use and return such Software including all copies and
documentation, and Unisys will grant a credit for the price paid to Unisys, less
a reasonable offset for use and obsolescence.

17.3  Unisys will not defend or indemnify Customer if any claim of infringement
or misappropriation (a) is asserted by a parent, subsidiary or affiliate of

extension of the license or service in accordance with the provisions of the

default relating to Sections 9 or 10 within 30 days.

                           SURETY Support Services Addendum

This Addendum amends the agreement referenced above by Agreement Number (the
"Agreement"), and applies to: (a) all orders for SURETY Support Services under
the Agreement upon duration of the then-current term.  Only definitions,
descriptions and levels of this Addendum will apply to these Services.

A.  DEFINITIONS

PRINCIPAL PERIOD OF MAINTENANCE ("PPM") means 8:00 AM to 5:00 PM, Client's local
time, Monday through Friday, excluding Unisys designated holidays.

OFF HOURS means all hours other than the PPM.

CLIENT OPERATIONAL HOURS ("COH") means all times when Client uses the Products.

which is deemed eligible by Unisys for exchange, that is identified by Client as
not in working order.

EXCHANGE UNIT means new, repaired, or previously used equipment in working order
that Unisys conveys to Client as a replacement for a Failed Unit. The Failed
Unit shall become the property of Unisys upon Client's receipt of the Exchange
Unit or, if later, upon receipt of the Failed Unit by Unisys.  Client warrants
that title to the Failed Unit, and Unisys warrants that title to the Exchange
Unit, shall be free and clear of all claims, liens, and encumbrances including
security interests.

Client's request for on-site SURETY service received during PPM no later than

B.  SERVICE DESCRIPTIONS

Unless specified on the Schedule or in this Section, the Initial Term for SURETY
Support Services will be 12 months and will commence on the later of the
Installation Date of the applicable Products or the date Unisys accepts the
Services.  Unless specified on the Schedule, the Initial Term of SURETY Support
Services for Products added to a system already enrolled under SURETY Support
Services will be coterminous with the applicable term of the Services on that
system and, for purposes of changes to SURETY Support Service charges, will be
deemed to have the same commencement date as the applicable term of the Services
on that system.  Following the Initial Term, SURETY Support Services will
continue on an annual renewal basis at Unisys then-current prices until
terminated or canceled according to the terms of this Agreement.  The specific
services for each Service Level are identified on the next page.

communication during the PPM on operating the Products, identifying Product
errors or malfunctions and advising on known detours, reporting software

expediting response to network down and system emergencies.  Some multivendor
products are not included in this service.

2.  USER COMMUNICATION SERVICES provides for reporting of suspected Product
errors or malfunctions or suggested new feature changes.  Unisys will make
reasonable efforts to provide detours or corrections for Unisys Products or

3.  ESSENTIAL ENGINEERING CHANGES are changes released by Unisys for safety
purposes or changes Unisys determines are essential to the performance of

clients located within a 60 mile radius from the center of a Unisys
concentration city, Unisys commits to have a client service representative
arrive at the Client's site within two (2) hours during PPM and within three (3)
hours outside of PPM.  Response is measured from the time that Unisys receives
the request for service from Client until Unisys arrives at Client's site.  If
Unisys moves its concentration city or the Client relocates its site so that the
Client's site is no longer within a 60 mile radius from the center of a Unisys
concentration city, Unisys reserves the right to adjust or eliminate the Service
Level.
