III.       BUSINESS ADMINISTRATION

A.         TERM OF AGREEMENT: This Agreement has an initial term of one (1) year
           from the Effective Date and shall automatically renew for successive
           one year terms unless earlier terminated. Either party may terminate
           this Agreement with written notice issued at least ninety (90)
           calendar days prior to the effective termination date. Any such
           termination shall only affect continuation of this Agreement and may
           not affect arrangements which were established as a result of this
           Agreement.

B.         ORDERING OF PRODUCTS:

           Unisys authorized personnel may issue purchase orders for Products
           under the provisions of this Agreement.

C.         GOVERNMENT CONTRACT PROVISIONS:

           If an order specifies that Products are for resale to a state, local
           or federal government, Seller agrees to be bound by the specific
           government contract provisions attached to or referred to in the
           order which Unisys is required by law to include in its subcontracts.
           Such orders are subject to Seller's acceptance.

D.         ORDER CONTENT / ACCEPTANCE:

           Each order shall specify quantities, prices, delivery schedules,
           destination, and other similar matters necessary for the individual
           transaction to be adequately described. Orders are deemed accepted by
           Seller if issued in accordance with the provisions of this Agreement.

E.         PURCHASE COMMITMENTS:

           Unisys shall not be obligated to order or purchase any specific or
           minimum quantity of Products under this Agreement. The sole
           obligation and liability of Unisys to Seller shall be limited to the
           actual quantities of Products specified by purchase orders issued
           pursuant to this Agreement.

F.         PRICING/TERMS: The net purchase price to Unisys is based on Seller's
           then-current Standard Product and Price List as of the date of
           shipment, less applicable discounts as set forth in Addendum A of
           this Agreement. Seller shall use reasonable efforts to provide
           Product and price change information to Unisys in electronic format
           and in a timely manner so as to allow updates of the Unisys ordering
           and sales support systems. The Unisys discount shall not change
           except by mutual agreement of the parties. Payment terms are Net 30
           days from receipt of a proper invoice. Unisys and Seller agree to
           negotiate "bid specific" pricing on an as needed basis to effectively
           meet customer needs or competition on specific sales opportunities.

G.         TERMINATION/CANCELLATION/RETURNS: Unisys may cancel orders for
           standard Products prior to shipment at no charge. Custom built or
           configured Products may be canceled at terms mutually agreeable to
           the parties. Either party may terminate this Agreement for default,
           subject to the


<PAGE>   4


           provision of written notice specifying such default and the allowance
           of a sixty (60) day cure period after receipt of such notice to cure
           the default. Unisys may return any non-defective properly packaged
           Product for a full refund.

H.         MOST FAVORED CUSTOMER: Seller warrants that the prices, payment terms
           and other terms and conditions stated for the Products, spare parts,
           and supplies covered by this Agreement are not less favorable than
           prices, payment terms or other terms and conditions accorded to
           Seller's most favored customer for like items in similar quantities.
           If, at any time during the term of this Agreement, Seller provides to
           such customer of Seller more favorable net prices, payment terms or
           other terms and conditions for products and services which are
           substantially comparable to those licensed or sold to Unisys
           hereunder, Seller shall extend such prices, payment terms and other
           terms and conditions to Unisys.

I.         LOGISTICS: Seller shall provide to Unisys all current Product
           lead-time information and update changes as needed. If lead-times
           become non-competitive or fail to meet market demand, Seller and
           Unisys will cooperate to reduce adverse impact on sales; an example
           would be to establish forecasts of orders to manage availability, and
           such order schedules would be modified to meet actual requirements in
           a timely manner with sufficient notice to Seller prior to scheduled
           delivery dates. Seller will promptly advise Unisys of any schedule
           changes on all open orders. Seller agrees to pay Unisys liquidated
           damages for late delivery in the amount of which the customer is
           contractually entitled from Unisys, provided that Unisys had advised
           Seller of the customer's inclusion of a liquidated damages provision
           and Seller had agreed to such provision. Seller shall provide
           expedited delivery capability to meet critical Products availability
           dates as needed. Seller shall ship Products to domestic and
           international destinations from the most cost effective
           manufacturing/inventory location. Seller is not authorized to make
           partial shipments unless Unisys requests or approves partial delivery
           in writing.

J.         PACKING: Products shall be suitably packed and shipped in accordance
           with standard commercial packing, the requirements of common
           carriers, and in such manner as to assure against damage from
           transportation, weather, and other environmental conditions. The
           Unisys purchase order number and part numbers, and any other
           information required by the customer, must be plainly marked on all
           invoices, inner-packages, outer packing, bills of lading, and
           shipping orders. See Addenda C and D for further information and
           requirements.

K.         SHIPPING:

           1. Unisys may, from time to time, direct the use of specific carriers
           or premium modes of transportation and arrange for direct billing of
           freight charges to Unisys. If such Unisys direction relative to
           premium modes of transportation is necessitated by Seller's failure
           to perform in accordance with established schedules, Seller shall
           bear any resulting increase in transportation and packing costs.

           2. All orders must ship complete. No partial shipments are authorized
           unless Unisys provides explicit written authorization to do so. No
           invoices should be submitted, nor will they be processed for payment
           until the order ships complete unless otherwise authorized.

L.         EXPORT: Unisys may request that Seller export Products to Unisys
           organizations or Unisys customers located outside of the United
           States, in which case Seller shall be the exporter of record. Seller
           shall then be responsible for compliance with applicable export
           regulations, including obtaining requisite export and/or re-export
           licenses, if any, in Seller's name covering said shipment


<PAGE>   5


           to the consignee (customer). Unisys shall provide Seller
           documentation necessary for Seller's use in application for export
           licenses or permits enough in advance of scheduled delivery dates so
           that Seller's associated shipping schedules shall not be impacted by
           government processing time. Any customs or duty charges will be the
           responsibility of Unisys.

M.         ADMINISTRATION/NOTICES: All official notices shall be in writing and
           shall be sent by certified mail, return receipt requested, or by wire
           communications (i.e., telex, twx, facsimile, etc.), to the respective
           Contract Administrator, at the address noted below, or as may be
           changed from time to time by notice similarly given. Written and
           other forms of notices applicable to orders shall be sent to Unisys
           procurement personnel at the addresses noted in the orders affected.

           1.         For Unisys

                                 General administration and liaison shall be
                                 performed by Valerie Meuleners, Manager
                                 Contracts and Pricing (referred to herein as

                                 designee or successor.

                                 Marketing liaison shall be performed by Frank

                                 Administrator"), or his designee or successor.

           2.         For Seller

                                 General administration and liaison shall be
                                 performed by Robert Emery, Vice President
                                 Administration & Finance (referred to herein as
                                 "Seller's Contract Administrator"), or his
                                 designee or successor.

                                 Marketing liaison shall be performed by Ty
                                 Glasgow, Director, Business Development
                                 (referred to herein as Seller's Marketing
                                 Administrator"), or his designee or successor.
                                                    .

           3. The Marketing Administrators may clarify, explain, provide further
           details, handle necessary marketing matters, implement marketing
           aspects, and develop administrative procedures, but shall have no
           authority to affect or change any of the terms and conditions of this
           Agreement. The exercise of Unisys rights of termination or
           cancellation and the exercise of other general rights of Unisys are
           reserved to Unisys Contract Administrator.



IV.        PRODUCT SUPPORT

A.         Express Warranties:

           1.          Seller warrants that:

                       a. The Products shall be free of defects in material and
           workmanship for a period of the greater of twelve (12) months from
           the date of installation or fourteen (14) months from date of
           invoice;

                       b. The Products shall be of new manufacture, in
           conformance with applicable specifications and regulatory agencies'
           requirements, free of defects in design, and free of any claim,
           encumbrance or lien; and

                       c. The Products shall be free of latent defects. As used
           herein, latent defects are defects that meet the following criteria:
           (i) such defects are not apparent to either party during


<PAGE>   6


           customary manufacturing or quality testing and/or inspection, (ii)
           such defects result solely from defective material, workmanship, or
           design and are not caused by misuse or misapplication of the Product,
           and (iii) such defects occur in at least three percent (3%) of a
           specific model of Product sold to Unisys during the life of the
           Product but limited to a maximum of ten (10) years after the initial
           delivery to Unisys of such Product,

           2. Seller shall repair or replace Products which are not in
           conformance with any of the foregoing warranties, and such obligation
           to repair or replace shall apply to the future performance of the
           Products so as to keep them in operating condition during each
           warranty term.

           3. Products repaired or replaced under the original warranty shall be
           warranted for the longer of the remainder of the warranty period on
           the original Products or three (3) months from reshipment of the
           repaired or replacement Products by Seller.

           4. Seller represents and warrants that it has title and the right to
           sell Products free and clear of all liens and encumbrances and the
           right to grant the software misappropriation or patent or copyright
           infringement in connection with the sale and licensing of the
           Products to Unisys.

           5. Seller's warranties, together with its service guaranties, shall
           run to Unisys and end users. Unisys inspection, approval, acceptance,
           use of, or payment for Products shall in no way affect Unisys
           warranty rights, whether or not a breach of warranty had become
           evident at the time. Seller shall honor customer warranty claims
           during the warranty period. However, Unisys reserves the rights to
           sell Product warranty uplifts or maintenance services to its clients
           and deliver such services directly to its clients during said
           warranty period.

B.         Remedies for Breach of Warranty

           1.         Any Product, which fails within the first thirty (30) days
                      after installation, shall be considered Dead on Arrival
                      ("DOA"). DOA Products shall be replaced by Seller
                      immediately upon notification of such occurrence and prior
                      to the return of such DOA Products. For other than DOA
                      occurrences, Unisys may return to Seller any Products in
                      breach of any warranty, and Seller shall reship the
                      repaired or replacement Product to Unisys within thirty
                      ( 30 ) days whenever possible and no later than ninety
                      ( 90 ) days after receipt of the nonconforming Products
                      returned by Unisys.

           2.         Unisys or its authorized agent shall submit warranty
                      claims to Seller in writing, within a reasonable time,
                      stating the nature and date of the claim.

           3.         Special billing procedures for replacement Products may be
                      established as needed based upon mutual agreement of the
                      parties.

           4.         Seller shall bear all freight charges associated with

                      Unisys.

           6.         Unisys rights under this Article are cumulative and
                      nonexclusive and in addition to all other rights and

           Unisys shall be authorized to perform first level support and
           maintenance for the Products in a manner, which meets or exceeds
           Seller's service provision standards whether or not Unisys sold the
           Products to the customer. Seller shall provide secondary support to
           Unisys, at Unisys request, in supporting and maintaining the
           Products, at no charge to Unisys when the Products are under warranty
           and at mutually agreed charges for time and material when the
           Products are under extended warranty or maintenance.

D.         Seller-Provided Technical Training

           1.         Unisys and Seller recognize the importance of training for
                      the successful support of all Products. Unisys agrees to
                      provide adequate staff and facilities to properly support
                      Seller's Products.

           2.         Seller shall, when requested by Unisys, provide sufficient
                      initial training sessions to train sixteen (16) people at
                      no additional charge. These initial training sessions will
                      cover installation procedures, configuration, operation,
                      trouble shooting and repair of the Products.

           3.         Seller shall provide all manuals and course materials for
                      the training specified in Paragraph 2, above. Seller

                      and distribute manuals and course materials and the right
                      to disclose the information contained therein for its own
                      training purposes.

                      Seller shall provide camera ready copy and/or electronic

                      related materials, as available, for Unisys use in setting
                      up its own training courses. Such manuals and course
                      materials furnished to Unisys, and all copies thereof made
                      by Unisys, shall become the property of Unisys.

           4.         The preferred methodology for delivering training provided
                      under Paragraph 2, above, is CBT (Computer Based
                      Training), Video, or Self-Study for first level support,
                      with more in-depth training reserved for second level
                      support. Should Instructor-led training be required, it
                      shall be done at times and locations mutually agreeable to
                      the parties; provided, however,

                      a.   if the training is to be performed at Seller's
                      facility, Seller shall furnish all things required for
                      such training and Unisys shall bear the cost of travel and
                      living expenses of its personnel.

                      b.   if the training is to be performed at other than
                      Seller's facility, Unisys shall provide adequate training
                      facilities and Seller shall bear the cost of travel and
                      living expenses for its personnel.

           5.         If improvements or enhancements are made or new Products
                      (s) are added to this Agreement, and training for same is
                      reasonably required by Unisys, Seller shall provide the
                      type of training noted in Paragraph D-2, above, as well as
                      manuals and course materials,

                      for sixteen (16) people, at no charge or cost to Unisys
                      except as set forth in Paragraph b, of D-4 above.

           6.         Seller shall, as requested by Unisys, provide additional
                      training courses and/or training as noted herein for
                      additional Unisys personnel.


E.         Software Update/Upgrade Distribution

                      4. Seller provides gold master copies of materials for
                      Unisys reproduction and distribution.

F.         Spare Parts

           Parts pricing shall be established at a discount equal to or greater
           than the discounts available from published list prices for Products
           under this Agreement. Seller shall ship parts in stock within one 
           ( 1 ) days after receipt of order and lead time plus five (5) days 
           for parts not in stock. Seller agrees to provide spares and/or repair
           services for a period of three (3) years after the end of Product
           life or the termination of this Agreement, whichever period is
           longer, at prices consistent with those afforded to other similarly
           situated resellers during the applicable time period.


G.         Information

           Seller will provide to Unisys a reasonable number of sets of Product
           documentation as needed to provide support to its customers, and the
           limited right to reproduce such documents from time to time for use
           within its support organization.. Seller must maintain a Product
           quality database, including records substantiating Product compliance
           with regulatory requirements and, upon reasonable request, allow
           Unisys to examine such database. Seller must have a problem
           prioritization and tracking system with response time commitments for
           problem resolution as mutually agreed by the parties.

H.         Diagnostic Software

           When applicable, Seller shall, at no cost to Unisys, provide Unisys
           with sufficient copies of existing Diagnostic Software for the
           Products. Seller hereby grants to Unisys non-exclusive and
           non-transferable license to copy and reproduce the Diagnostic
           Software solely for the purpose of the Unisys maintenance
           organization to meet the demands of the service delivery. The terms
           of this license shall continue until such time that Unisys no longer
           provides Product support services to its end-users.

J.         Escrow

           Seller agrees that Unisys shall have the option to require Seller to
           place source code and other technical documentation into escrow,
           should it become evident that Seller will no longer be able to
           perform pursuant to this Agreement. This right is deemed to include
           firmware which is downloadable to "flash" memory.


V.         LEGAL PROVISIONS

This Article contains standard legal terms and conditions relating to the
purchase and resale of Products under this Agreement.


A.         CONFIDENTIAL INFORMATION AND DISCLOSURE

1)         Any information which either party may disclose to the other party
           shall not be deemed to be confidential and shall be acquired free
           from any restriction, unless the information is proprietary to the
           disclosing party and, if it is disclosed in tangible form, the
           disclosing party marks such information as being confidential to it
           by marking such information as "Proprietary", "Restricted", or
           "Confidential." Any confidential information disclosed orally shall
           be identified as confidential at the time of disclosure and
           thereafter reduced to tangible form with a copy, prominently marked
           as aforesaid, delivered to the receiving party within ten (10) days
           of the verbal disclosure. When a writing contains both confidential
           and nonconfidential information, the disclosing party shall
           specifically note the information, which is confidential.

           However, notwithstanding the above, the identities, addresses, and
           other specific information regarding Unisys customers provided by
           Unisys to Seller shall be deemed Unisys confidential information.

2)         Each party shall exercise the same degree of care to avoid the
           publication or dissemination of the confidential information of the
           other party as it affords to its own confidential information of a
           similar nature which it desires not to be published or disseminated,
           but in any case not less care than a reasonable person would
           exercise.

3)         Confidential information disclosed under this Agreement shall only be
           used by the receiving party in the furtherance of this Agreement or
           the performance of its obligations hereunder.

4)         The obligations of the parties with respect to confidential
           information shall survive the termination or cancellation of this
           Agreement. However, neither party shall be obligated to protect
           confidential information of the other party which:

                      a.   is rightfully received by the receiving party from
                      another party without restriction, or

                      b.   is known to or developed by the receiving party
                      independently without use of the confidential information,
                      or

                      c.   is or becomes generally known to the public by other
                      than a breach of duty hereunder by the receiving party, or

                      d.   has been or is hereafter furnished to others without
                      restriction on disclosure, or


<PAGE>   10


                      e.   is known or available to the receiving party by
                      inspection or analysis of products available in the
                      market.

           The obligation not to use or disclose said confidential information
           shall end; either, two (2) years after the date of receipt of said
           confidential information, or years after the termination of this
           Agreement, whichever is later, except with respect to software for
           which the obligation shall continue until the occurrence of any of
           the events listed in Subparagraphs a through e, above.

5)         Unisys shall be permitted to disclose said confidential information
           to subsidiaries, Affiliates, third parties and subcontractors for
           their use in the furtherance of this Agreement in accordance with the
           rights and licenses granted; provided, however, that subsidiaries,
           Affiliates, third parties and subcontractors agree to protect such
           information to the extent provided herein.

6)         Nothing contained in this Section V.A., or elsewhere, shall be
           construed as preventing Unisys from marketing, selling, leasing,
           renting, or sublicensing the Products in the same manner as it may
           then market, sell, lease, rent, or sublicense its other Products.
           Unisys and subsidiaries, Affiliates and third parties may disclose
           Seller's confidential information to end users for the purposes of
           training, operation, maintenance and marketing of the Products;
           provided, however, that they shall require such end users to keep
           confidential any Seller confidential information so transferred to
           the same extent Unisys requires confidentiality with regard to its
           own confidential information under similar circumstances.

B.         DISCLAIMER

EXCEPT AS EXPRESSLY STATED HEREIN, NEITHER PARTY HAS MADE ANY WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED BY OPERATION OF LAW OR OTHERWISE, CONCERNING
THE PRODUCTS TO BE PROVIDED HEREUNDER, THE SCOPE OR DURATION OF ANY MARKETING
EFFORT WHICH Unisys MAY UNDERTAKE, OR THE SUCCESS OF ANY SUCH MARKETING EFFORT.
NEITHER PARTY HAS RELIED ON ANY EXPRESS OR IMPLIED REPRESENTATION OF THE OTHER
PARTY, WRITTEN OR ORAL, AS AN INDUCEMENT TO ENTERING INTO THIS AGREEMENT.

C.         LIMITATION OF LIABILITY

EXCEPT AS PROVIDED IN SECTION V.D. HEREOF, NEITHER PARTY SHALL BE LIABLE FOR ANY
INCIDENTAL, INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES, INCLUDING, BUT NOT
LIMITED TO, LOST PROFITS, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY
OF SUCH DAMAGES.

D.         INFRINGEMENT/INDEMNITY

Seller agrees to indemnify and hold harmless Unisys, its subsidiaries,
Affiliates and subcontractors, and third party reseller customers, and end user
customers of any of the aforesaid (the "Indemnified Parties") from any claim,
liability, damage or expense including but not limited to legal expenses, of
whatever kind for or on account of patent infringement, copyright infringement,
misappropriation of trade secrets or violation of other proprietary rights in
connection with or relating to the use, copying, reproduction, distribution,
selling, licensing or other disposition of the Products. Seller agrees to defend
or settle all suits and proceedings arising out of any of the foregoing
provided, however, that Unisys shall give Seller prompt


<PAGE>   11


written notice of all suits or threats of suit and other such claims concerning
patent or copyright infringement or misappropriation of trade secrets or other
intellectual property against any of the Indemnified Parties. Unisys, at its own
expense, shall have the right to participate in Seller's defense of any such
action through Unisys' own counsel. In the event that Seller fails, after
notice, to adequately defend or settle any action which it is obligated to
defend or settle under this Section V.D., Unisys shall have the right of
prosecuting and defending such action or actions and to collect such costs and
expenses (including attorney's fees) from Seller and further shall have the
right to charge Seller with any and all awards, damages, and court costs in such
action or actions and to collect such awards, damages, and court costs from
Seller. If any Product is held to be an infringement or misappropriation for
which indemnification is to be provided by Seller, and its use is enjoined,
Seller shall, at Seller's option and expense, either:

           1.         Procure for the Indemnified parties the right to continue
                      to utilize the Product pursuant to the license granted
                      herein, or

           2.         Replace or modify the Product in such a way that they
                      shall not continue to constitute such infringement or
                      misappropriation.

Seller shall not be liable under this Section V.D. if the Product has been
modified by any of the Indemnified Parties and such modification is solely the
cause of any such infringement or misappropriation, unless such modifications
were made in accordance with Seller's instructions or with Seller's approval.

E.         TRADEMARKS AND TRADE NAMES

Nothing contained in this Agreement shall be construed as licensing either party
to use any trademark or trade name owned or used by the other party without the
prior written consent of the other party. However, Unisys, its subsidiaries,
Affiliates and third parties shall have the unrestricted use of the terms stated
in this Agreement (and any other or subsequent term used by Seller to identify
the Products) in connection with the use, marketing, copying, distribution,
sale, rental, lease, licensing, and sublicensing of the Products. When marketing
the Products, Unisys, its subsidiaries and Affiliates shall have the right to
use their own trademarks or trade names when referring to the Products.

F.         FORCE MAJEURE

Neither Unisys nor Seller shall be liable to the other for delays in the
performance of or completion of this Agreement if such delay is caused by
strikes, riots, wars, government regulations, acts of God, fire, flood or other
similar causes beyond its control; provided, however, if such delay exceeds
sixty (60) days, the other party shall have the option, exercisable by written
notice, to terminate this Agreement by notice in accordance with Section III.M
hereof.

G.         ASSIGNMENT AND BENEFITS

All the terms and conditions of this Agreement shall be binding upon, inure of
the benefit of, and is enforceable by the respective successors and permitted
assigns of the parties hereto. Except as specifically stated in this Agreement,
neither this Agreement nor any of the rights, interests or obligations of any
party hereunder shall be assigned or delegated by either party hereto without
the prior written consent of the other. Such consent shall not be withheld
unreasonably. Any unauthorized assignment or delegation shall be null and void.
Notwithstanding the foregoing, either party may assign or otherwise transfer its
rights and obligations to successors in interest (whether by purchase of stock
or assets, merger, operation of law, or otherwise) of that portion of its
business related to the subject matter hereof.

           resolved by agreement between the Contract Administrators.

2)         The parties shall make a good-faith effort to amicably settle by
           mutual agreement any dispute that may arise between them under this

           claims which relate in any way to this Agreement finally and
           conclusively by arbitration. The arbitration shall be conducted in

           shall be conducted in Virginia by one arbitrator selected from a
           panel of persons having experience with and knowledge of electronic
           computers and the computing business. The arbitrator selected will be
           an attorney. The arbitrator shall be chosen by both parties; if the
           parties are unable to agree, the arbitrator shall be selected by the
           AAA. Judgment upon the award may be entered in any court having
           jurisdiction thereof or having jurisdiction over the applicable party
           or its assets. Either party will be free to apply at any time to a
           court of competent jurisdiction for interim or conservatory relief
           and will not be deemed to have breached this agreement to arbitrate
           or to have infringed the powers of the arbitrator in doing so.

           upon the performance of any of the terms, covenants or conditions of
           this Agreement or to exercise any right hereunder shall not be

           joint venturers, agent and principal, employer and employees, or any
           relationship other than that of independent contractors. At no time

           Seller agrees that it shall not engage directly or indirectly, either
           for itself, or with or for any other person or corporation, in any
           work or undertaking which shall conflict with or create any legal
           impediment against Seller's performance of its obligations under this
           Agreement and the rights and licenses granted to Unisys hereunder.
           Seller represents that there is no such present conflict of interest
           or any such legal impediment.

           are, in whole or in part, divested by Unisys during the term of this
           Agreement shall, nevertheless, retain all rights pursuant to this
           Agreement which such divested entity had in the Products prior to
           such divestiture. The rights and obligations of such divested
           entities regarding the Products shall be the same as, but limited to,
           Unisys rights and obligations directly applicable to the use,
           payments and Seller support of the Products, and such divested
           entities shall have no other rights or obligations pursuant to this
           Agreement. All sales by such divested entities shall be contributory
           toward the achievement of any quantity and volume pricing discounts,
           and payments shall be at the then applicable net prices for the
           Products. Unisys shall notify Seller of such divested entities.

8)         Counterparts

           This Agreement may be executed in any number of counterparts, each of
           which together shall constitute one and the same instrument.

9)         Publicity

           Seller shall not, except as may be required by law or federal
           regulation, or except with the prior written permission of Unisys,
           publicly advertise this Agreement or disclose its contents.

10)        Risk of Loss

           Until such time as the deliverable items have been delivered to the
           Unisys designated ship to address or the applicable end user
           location, all risk of loss shall be Seller's.

11)        Entire Compensation

           Except as may be specifically provided otherwise in this Agreement,
           Seller's performance and fulfillment of its other obligations under
           this Agreement, and the granting of licenses and rights to Unisys
           shall be at no additional cost or charge to Unisys.

12)        Personal Injury/Property Damage

           Each party (the "Indemnifying Party") shall hold harmless and defend
           the other party (the "Indemnified Party") from any claim of personal
           injury or property damage arising from any act or omission of the
           Indemnifying Party. The obligations of the Indemnifying Party under
           this Indemnification provision are conditional upon: (a) the
           Indemnified Party providing prompt written notice to the Indemnifying
           Party of any claim referred to above and any related action, suit, or
           other proceeding; (b) the Indemnified Party's permitting the
           Indemnifying Party to defend or settle such claim, action, suit, or
           proceeding (provided the Indemnified Party must approve in its sole
           discretion any settlement terms that obligate the Indemnified Party);
           and (c) the Indemnified Party provided the Indemnifying Party (at the
           Indemnifying Party's expense) all reasonable assistance in

           defending or settling the claim, action, suit, or proceeding. Upon
           request by Unisys, Seller shall furnish evidence of insurance
           coverage for such injury and damage.

13)        Notice of Delay

           Whenever any occurrence (e.g., an event of Force Majeure or a filling
           under a bankruptcy law) is delaying or threatens to delay Seller's
           timely performance under this Agreement, Seller shall promptly give
           notice thereof, including all relevant information with respect
           thereto, to Unisys.

14)        Compliance with Law

           In the performance of this Agreement, the parties shall comply with
           all applicable laws, executive orders, regulations, ordinances,
           rules, proclamations, demands and requisitions of national
           governments or of any state, local or other governmental authority
           which may now or hereafter govern performance hereunder including all
           laws, executive orders, regulations, ordinances, rules and
           proclamations regarding Equal Employment Opportunity, the exporting
           of technology, and withholding for income taxes.

15)        Foreign Offset Credits

           If any foreign government offset credits result from the performance
           of this Agreement, it is agreed that they shall be the sole property
           of Unisys.

16)        Survival of Provisions

           In addition to the rights and obligations which survive as expressly
           provided for elsewhere in this Agreement, the Articles and Addenda
           which by their nature should survive, shall survive and continue
           after any termination or cancellation of this Agreement.

17)        Entire Agreement

           This Agreement states the entire agreement between the parties with
           respect to the subject matter hereof and shall supersede all previous
           proposals, negotiations, representations, commitments, writings,
           agreements and other communications, both oral and written, between
           the parties. This Agreement may not be released, discharged, changed
           or modified, except by an instrument in writing signed by a duly
