                         predetermined manner; and to store and provide output
                         of date information in ways that are unambiguous as to

               environment for all of COMPANY's activities.

               promptly correct, at no charge, any problems with respect to the
               foregoing to achieve compliance therewith, provided the error is
               reported to AMDOCS within the Warranty Period.


         iv)   AMDOCS does not make any representations or warranties as to the
         ability of the Customized Product to be Year 2000 Compliant when used
         or interfaced with other system(s), software, hardware, data or
         equipment which is not Year 2000 Compliant or which does not have a
         properly functioning wrapper allowing correct exchange of date-related
         data, unless such a wrapper is part of the Customized Product.
         Operability with external interfaces is subject to be predefined in the
         DFS and in accordance therewith. Furthermore, the Year 2000 warranties
         above shall not apply in the event that the Platform or any module of
         the Licensed Products or Customization is altered, modified or adjusted
         in a manner that directly or indirectly affects Year 2000 compliance,
         and such alteration, modification or adjustment is made by COMPANY or
         any third party without AMDOCS' prior written consent.


         AMDOCS will have no liability for the Year 2000 readiness of, or for
         any Year 2000 defect or error or deficiency in any system, software or
         service which is not provided by AMDOCS under this Agreement.

3.5.3    AMDOCS further represents and warrants to COMPANY as follows:

<PAGE>   13

3.5.3.1 AMDOCS owns or possesses all necessary licenses or other valid rights to
use and license all Licensed Products and Customized Products, and all Licensed
Products, Customized Products and Customizations shall not infringe or
misappropriate any Intellectual Property Right of any third party, and the
Customization Services, Maintenance Services and Support Services shall not
cause any such infringement or misappropriation or constitute unfair competition
of any kind.

3.5.3.2 The execution, delivery, and performance of this Agreement (i) have been
authorized by all necessary action, if any; (ii) do not violate any law, rule,
or regulation or the terms of any order, judgment, or decree to which AMDOCS is
subject, or the terms of any material agreement to which AMDOCS or any of its
assets may be subject; and (iii) are not subject to the consent, approval, or
other action of any third party.

3.5.3.3 This Agreement is a valid and binding obligation of AMDOCS, enforceable
against AMDOCS in accordance with its terms.

3.5.3.4 All Customization Services, Maintenance Services and Support Services
shall be performed in a professional manner, shall be of a high grade, nature,
and quality, and shall conform in all material respects with the requirements of
this Agreement and the Orders.

3.5.4 DISCLAIMER

         THE FOREGOING WARRANTIES (AND ANY OTHER WARRANTIES EXPRESSLY SET FORTH
         IN THIS AGREEMENT) ARE IN LIEU OF ALL OTHER WARRANTIES, WHETHER ORAL,
         WRITTEN, EXPRESS, IMPLIED OR STATUTORY. THERE ARE NO OTHER WARRANTIES.
         WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE AND
         ANY OTHER STATUTORY WARRANTIES OF ANY KIND ARE HEREBY WAIVED. COMPANY
         EXPRESSLY AGREES THAT AMDOCS DOES NOT REPRESENT OR WARRANT THAT THE
         LICENSED PRODUCTS OR THE CUSTOMIZED PRODUCTS WILL OPERATE ON COMPUTER
         HARDWARE OR OPERATING SYSTEMS OTHER THAN THE PLATFORM.

3.6      MAINTENANCE

         AMDOCS shall provide to COMPANY Maintenance Services in accordance with
         the provisions of Section 5 and an applicable Order.

3.7      LICENSE FEES

3.7.1 The License Fee to be paid by COMPANY for the license to use a Licensed
Product and related Customized Product(s) will be specified in the applicable
Order. The License Fee shall be comprised of an Initial License Fee ("ILF") and
Subsequent License Fee ("SLF").

<PAGE>   14

3.7.2 The ILF for a use of a Licensed Product by COMPANY inside the Territory
and related Customized Product(s) will be determined based on the number of
Subscribers in the Territory for which COMPANY desires to acquire the right to
use such Licensed Product and related Customized Product(s) at the time an Order
for that Licensed Product and related Customized Product(s) is issued, but not
less than the actual number of COMPANY's Subscribers at such time, as
represented by COMPANY to AMDOCS and specified in the Order for the Licensed
Product and related Customized Products. The license fee is a cumulative fee
comprised of the relevant base fee and incremental fees for the relevant number
of Subscribers.

3.7.3 The ILF for a use of a Licensed Product by COMPANY in any market outside
the Territory will be based on the number of Subscribers in such market at the
time the Licensed Product is first used. In the event that such a market
contains more than 100,000 Subscribers, then COMPANY shall pay ILF as calculated
in Order No. 1 and shall pay SLF at a rate of 85% of the SLF table as specified
in Order No. 1. In the event that the number of Subscribers in such a market is
less than or equal to 100,000, then COMPANY: (i) shall not be required to pay
ILF, and (ii) shall pay SLF for the actual number of such Subscribers at the SLF
rate table in Order No. 1; provided, however, that such rates shall commence
from the first such Subscriber upwards, rather than commencing at 800,000
Subscribers, and shall be calculated in accordance with 85% of the SLF table in
Order No. 1, always commencing with a deemed 800,000 subscribers and adding the
actual number of Subscribers. The number of Subscribers shall be calculated
annually in accordance with Section 3.8.4.

3.7.4 COMPANY's number of Subscribers (as specified in the applicable Order for
a Licensed Product and related Customized Product(s) and/or Customizations) will
be reviewed annually, commencing on the first business day after issuance of
COMPANY's annual financial statements following execution of such Order but not
later than April 15th of each year (the "Verification Date"). The number of
Subscribers as of each Verification Date shall be notified by COMPANY to AMDOCS,
and certified to AMDOCS by COMPANY's independent auditors within sixty (60) days
of the Verification Date. COMPANY will ensure that such certification shall be
made directly by such auditors to AMDOCS within such sixty (60) day period.

3.7.5 If the number of COMPANY's Subscribers at the time of such annual review,
as compared to the number of Subscribers at the later of the time the Order for
the Licensed Product was issued or as at the previous Verification Date has
increased, then COMPANY will pay AMDOCS SLF in accordance with such increase
unless otherwise specified an applicable Order. The amount of SLF to be paid,
based on increments of increased numbers of Subscribers, will be specified in
such Order.

3.7.6 The license fees for a COMPANY Affiliate that uses a Licensed Product will
be based on the number of Subscribers of such COMPANY Affiliate on the date the
applicable Licensed Product is first used (the "Affiliate Subscribers"). If the
number of Affiliate Subscribers is greater than the number of COMPANY
Subscribers on the last

<PAGE>   15

Verification Date, then the COMPANY Affiliate shall be required to pay ILF and
SLF as specified in Order No. 1. If the number of Affiliate Subscribers is less
than or equal to the number of COMPANY Subscribers on the last Verification
Date, then such COMPANY Affiliate (i) shall not be required to pay ILF, and (ii)
shall pay SLF for the number of Affiliate Subscribers, as specified in Order No.
1.

3.7.7 A COMPANY Successor that uses a Licensed Product will not be required to
pay any additional license fees in order to continue to use the Licensed Product
(except for the normal Subsequent License Fees provided for herein); provided,
however, that such COMPANY Successor may only use such Licensed Product in the
locations in which COMPANY and its Affiliates are using the Licensed Product at
the time the rights of COMPANY under this Agreement are assigned to COMPANY
Successor. If COMPANY Successor desires to use the Licensed Product in locations
other than those used by COMPANY and its Affiliates at the time the rights of
COMPANY under this Agreement are assigned to COMPANY Successor, COMPANY
Successor will be required to pay an additional license fee as mutually agreed
between COMPANY Successor and AMDOCS.

3.7.8 Upon reasonable prior notice, AMDOCS shall have the right, once annually,
through an independent auditor to be appointed by AMDOCS at AMDOCS' expense, to
audit during normal business hours COMPANY's records relating to COMPANY's
number of Subscribers. If the number of Subscribers revealed by such annual
audit is five (5%) percent or more than the number provided to AMDOCS by
COMPANY's annual audit, then without derogating from AMDOCS' rights hereunder,
COMPANY shall pay SLF in accordance with the results and reimburse AMDOCS the
costs of such independent audit.

3.8      PAYMENT OF THE LICENSE FEE

3.8.1 The ILF for each Licensed Product will be paid by COMPANY pursuant to the
payment schedule specified in each applicable Order.

3.8.2 Unless otherwise specified in an applicable Order, COMPANY will pay SLF in
its entirety to AMDOCS no later than sixty (60) days following the Verification
Date, in accordance with the provisions of Sections 3.7.4 and 3.7.5.

3.8.3 Upon expiration or other termination of this Agreement, COMPANY's
obligation to pay ILF and SLF shall expire.

          Products not initially considered by the parties as part of the scope
          of the Customized Product or Customization Services to be provided
          hereunder or changes after the approval of the DFS will be deemed to

         its Project Manager without the consent of COMPANY, which consent shall
         not be unreasonably withheld. The Project Managers will meet on a
         regular basis to discuss and review the progress of the work by both
         parties under the applicable Orders.

Products, consisting of correction of errors found in modules of the current
version of such products, provision of improvements, enhancements, modifications
and new releases (not including major new modules defined by AMDOCS as
separately priced components of the Licensed Product or the Ensemble modules),
and reasonable consultation by telephone ("Maintenance Services"), subject to
payment of the Maintenance Fees as set forth hereinafter. COMPANY shall order
Maintenance Services pursuant to an Order hereunder. COMPANY has ordered
Maintenance Services pursuant to Order No. 2 (attached hereto as Appendix 2).

5.1.2 Maintenance Services hereunder shall commence (provided an applicable
Order has been issued and accepted as aforesaid) upon expiration of the Warranty
Period. Maintenance Services hereunder shall be available during the term of
this Agreement, provided that all Maintenance Fees are duly paid, and further
provided there is no termination of the Maintenance Services during that period.

5.1.3 The procedure for error correction shall be as follows: the OGS team
(referred to in Section 4.7.1) shall be notified of the error condition
discovered; the OGS team will endeavor to determine the source of such error
condition, whether it is in the Platform, in one of the modules of the Licensed
Products, an operational error, or some other source; in the event that one of
the Licensed Products is the source for said error condition, the OGS team will
notify AMDOCS promptly of said error and provide AMDOCS, in reasonable detail,
with all the information obtained by it with respect to such error, in order to
assist AMDOCS to correct such error; AMDOCS will identify the cause for the
error and will provide the solution and programs required to correct such error
and to perform cleanup to the OGS team; the OGS team will run such programs to
(a) implement the correction and (b) implement any clean-up activity required.
If it is found that an error condition which was reported to AMDOCS is not an
error in the Licensed Product (unless otherwise specified in the applicable
Order, Maintenance Services are provided for the Licensed Product, only), AMDOCS
will have the right to charge COMPANY for the time spent in handling and
diagnosing the matter, at its hourly rates set out in Exhibit A.

5.1.4 The Warranty and the Maintenance Services shall apply to all modules of
the Licensed Products, including those that are altered, modified or adjusted in
any manner by COMPANY. In the event that any services are rendered by AMDOCS to
COMPANY resulting from or caused by modifications, alterations, or adjustments
of the Licensed Products that were not made by AMDOCS, then AMDOCS shall charge
COMPANY for such services at its hourly rates set out in Exhibit A. In the event
that COMPANY and AMDOCS enter into a joint project, then the portion of the
project for which AMDOCS shall provide Maintenance Services will be specified in
the Order.

5.2      MAINTENANCE FEE

5.2.1 The consideration for the Maintenance Services ("Maintenance Fee") for
each Maintenance Period for which Maintenance Services are ordered by COMPANY
shall be an amount equal to the lower of: (i) fifteen percent (15%) of AMDOCS'
discounted License Fees for the applicable Licensed Product; or (ii) the
Maintenance Fee for the previous year plus ten percent (10%). The Maintenance
Fee for the first Maintenance Period shall be fifteen percent (15%) of AMDOCS'
discounted License Fees for the applicable Licensed Products. Notwithstanding
the foregoing, the annual Licensed Product Maintenance Fee for each COMPANY
Affiliate shall be an amount equal to fifteen percent (15%) of AMDOCS'

addition to the above annual Maintenance Fee, (i) ten (10%) percent of the
applicable Customization Services fees for the first three (3) years after the
end of the Warranty Period; and (ii) seven and one-half (7.5%) percent of the
applicable Customization Services fees for the next three (3) years; and (iii)
zero (0%) percent thereafter. The Maintenance Fees in this Section shall also
apply to separate modules of the Customized Product, until AMDOCS incorporates
such separate modules into the generic ENSEMBLE modules. At such time, even if
during the timeframes specified in sub-sections 5.2.2(i) and 5.2.2(ii), COMPANY
will not be required to pay Maintenance Fees for Maintenance Services for such
modules.

5.2.3 The Maintenance Fee for each Maintenance Period will be invoiced and paid
by COMPANY in advance in two (2) semi-annual equal installments, the first
payable on or before the commencement of the Maintenance Period and the second
within six (6) calendar months of the commencement of that Maintenance Period or
of the previous payment date, as the case may be.

5.2.4 If, for any reason, COMPANY did not request that Maintenance Services
commence upon conclusion of the Warranty or has terminated or not renewed a
Maintenance Services Order, or if, after some period of time during which
COMPANY does not request from AMDOCS Maintenance Services, COMPANY requests
AMDOCS to commence (or, as the case may be, to recommence) Maintenance Services,
AMDOCS, at its discretion and notwithstanding anything to the contrary herein,
may agree to provide such services.

         shall have the option of making the purchase from the lower cost
         provider. In the event that third party hardware and software
         components are purchased through AMDOCS, AMDOCS will purchase
         components through suppliers acceptable to COMPANY. Regardless of the
         method of purchase, COMPANY shall retain title to all components
         comprising the Platform.

         interest from the date invoice is received at the rate of two (2)
         percent per annum above the prime rate of Chase Manhattan Bank as
         quoted by the Wall Street Journal on the date of the applicable
         invoice, unless the amount in arrears is disputed in good faith and
         until such

<PAGE>   25

         dispute is resolved. However, the undisputed amounts shall be paid by
         COMPANY without delay as aforesaid and, if AMDOCS' claim for payment of
         the disputed amount in arrears is resolved in favor of AMDOCS, COMPANY
         shall pay AMDOCS said interest as if such unpaid amount was not
         disputed at all. Additionally, and without affecting the foregoing,
         COMPANY's failure to pay any undisputed payment under this Agreement
         within one-hundred and twenty (120) days after such payment becomes due
         shall be considered a material breach of this Agreement by COMPANY.

7.4      PRICE PROTECTION

         The rates, payments and charges referred to in Section 7.1 and other
         charges set forth in this Agreement and the Orders attached hereto are
         fixed for one year from January 1st of each year. Upon ninety (90)
         days' prior written notice to COMPANY, said rates, fees and charges may
         be changed once in any period of one year in accordance with the annual
         percentage change (related to the twelve month period preceding such
         increase) in the U.S. Consumer Price Index-All Urban Consumers, U.S.
         City Average, as published by the Bureau of Labor Statistics, U.S.
         Department of Labor (the "Index") plus five percent (5%). However, if
         the annual percentage change in the Bureau of Labor Statistics, U.S.
         Department of Labor for computer software professionals will increase
         fifteen (15%) percent above the Index, the parties will discuss a
         larger increase. If the parties cannot agree on such larger increase,
         the matter shall be resolved in the manner provided for in Section 8.15
         for the settlement of disputes.

7.5      TAXES

         AMDOCS' rates, fees and other charges set forth in the Agreement do not
         include value added tax, sales tax, consumption tax and similar taxes
         or duties as well as any city, municipal, state or corporate taxes or
         any withholding taxes, whether currently imposed or to be imposed in
         future, other than taxes due upon AMDOCS' net income or the Washington
         State business and occupation tax. If any such tax or duty is found to
         be applicable, the appropriate amount of tax or duty shall be invoiced
         to and paid by COMPANY to AMDOCS at the same time and on the same
         conditions as applied to the payment due.

8.       GENERAL TERMS AND CONDITIONS

8.1      TERM OF THE AGREEMENT

         This Agreement shall become effective as of the date of execution
         hereof by both parties and shall continue for a period of eight (8)
         years unless terminated by mutual written consent of both parties or
         ended otherwise as provided for in this Agreement.

8.2      ORDERS

8.2.1 The procurement by COMPANY from AMDOCS of licenses to use the Licensed
Products and related Customized Products, Customization Services, Maintenance
Services or Support Services hereunder shall be done by the issuance and
acceptance of Orders. Each Order shall be deemed to incorporate (1) the terms
and conditions of this Agreement, to the extent applicable; (2) the DFS
applicable to such Order, if any; and (3) any relevant subordinate documents
attached to or referenced in such Order.

8.2.2 Subject to the provisions of Section 8.13, each Order and this Agreement
shall constitute the entire agreement between COMPANY and AMDOCS relating to a
particular Order. However, in case of any inconsistency or contradiction between
the provisions of this Agreement and the provisions of an Order, the provisions
of the Order will prevail as to the subject matter of such inconsistency. An
Order may not be modified or amended except as mutually agreed in writing by
COMPANY and AMDOCS.

8.2.3 Each Order shall include such specific provisions as agreed upon by the
parties and as required by the applicable Sections of this Agreement and its
Exhibits. The parties agree that special provisions may be necessary to provide
for specific conditions associated with the Customized Product, Support
Services, Customization Services or Maintenance Services, and that the required
special provisions that the parties agree upon shall pertain solely to the
Customized Product, Support Services, Customization Services or Maintenance
Services respectively covered by such Order(s).

8.2.4 In the event that an Order is not accepted or rejected by AMDOCS within
thirty (30) days of its receipt by AMDOCS, such Order will be deemed rejected.
AMDOCS may reject an Order if it is not reasonably feasible or practical for
AMDOCS to accept such Order as a result of the time schedule for performance of
such Order, the nature of the services requested by COMPANY or the fees
proposed, or if such Order is not consistent with the provisions of this
Agreement. An Order will be binding upon the parties only if executed, confirmed
or acknowledged in writing by both parties. Execution, confirmation or
acknowledgment in writing of an Order by both parties will bind both parties to
honor dates, amounts and other ordering information shown on the Order,
including supplemental provisions contained therein.

<PAGE>   27

8.2.5 Order Nos. 1 and 2 are attached hereto as Appendices 1 and 2,
respectively. Such Orders are being accepted and executed by the parties
simultaneously with their execution of this Agreement.

8.3      INTELLECTUAL PROPERTY RIGHTS

8.3.1 COMPANY acknowledges AMDOCS' claim that copyright, trade secrets,
trademarks and any other intellectual property rights as the case may be,
subsists in the Ensemble, the Licensed Products, and that COMPANY shall have
neither copyright nor ownership or any such other intellectual property right in
the Ensemble, the Licensed Products and any enhancements thereto or derivatives
thereof (subject to Section 8.3.2 below). Notwithstanding the foregoing, COMPANY
shall retain all right, title and interest in and to all COMPANY Intellectual
Property Rights, and AMDOCS does not acquire any right, title or interest,
express or implied, in any COMPANY Intellectual Property Rights.

8.3.2 AMDOCS hereby assigns and will take all reasonable steps necessary to
assign its right, title and interest in and to the Customization to COMPANY.
Such Customization shall be deemed to be a work made for hire. Unless otherwise
specified in an Order, AMDOCS shall have no license or right to use, market,
sell, distribute or otherwise exploit any Customizations. AMDOCS shall have the
right to redevelop any part of the Customizations and to market, license, sell
and/or distribute such redevelopments to AMDOCS' customers.

8.4      TITLE

         Title to the Licensed Products and any enhancements thereto or
         derivatives thereof shall remain with and belong to AMDOCS and shall
         not pass to COMPANY. COMPANY expressly acknowledges that its right to
         use the Licensed Products and the Customized Product in accordance with
         the terms of this Agreement, does not extend to, or encompass, title to
         or ownership of such products, except as provided in Section 8.3.2.

8.5      CONFIDENTIALITY

8.5.1 The provisions of the Confidentiality Agreement between the parties dated
as of January 14, 1997, a copy of which is attached hereto as Exhibit B, shall
apply with regard to the performance of this Agreement by the parties hereto.
Such provisions shall survive the expiration of or termination of this Agreement
or any Order for any reason whatsoever. Any subcontractors of or other third
parties who have a need to know or may have access to AMDOCS' or COMPANY's
proprietary and confidential information shall first sign AMDOCS' or COMPANY's
non-disclosure agreement, as applicable, in the forms attached hereto as Exhibit
C, or a comparable document containing similar protections.

8.5.2 Prior to providing any third party with access to the source code of the
Customized

<PAGE>   28

Product, COMPANY shall first inform AMDOCS of the identity of such third party.
In the event that AMDOCS determines that such third party is an AMDOCS
Competitor (as defined hereinafter in this Section 8.5.2), AMDOCS shall so
inform COMPANY and COMPANY shall not provide such third party with access to the
source code of the Licensed Products and/or the Customized Product. For purposes
of this Section 8.5.2, an "AMDOCS Competitor" is any third party that licenses
and/or develops customer care and/or billing systems for telecommunications.

8.6      ENTICEMENT OF STAFF

         Each of the parties agrees not to hire or employ any of the other
         party's employees or their respective subcontractors' employees who are
         assigned full or part-time to activities which are part of the
         performance of this Agreement, except by mutual written consent of such
         other party, within two (2) years of such employee or subcontractor's
         employee ceasing to be employed by his/her respective employer. The
         provisions of this Section 8.6 shall survive the expiration or
         termination of this Agreement or any Order for any reason whatsoever
         and shall remain in full force and effect for a period of two years
         thereafter.

8.7      WORK RULES AND ACCESS TO FACILITIES

8.7.1 Each party's respective employees or representatives who use the other
party's premises or facilities hereunder will be subject to the reasonable
restrictions imposed by the other party. Such employees or representatives will
comply with all reasonable rules applicable to the host COMPANY's employees.

8.7.2 Each party acknowledges that the performance by the other party of such
other party's obligations hereunder requires information and cooperation between
the parties. Without limitation to each party's rights under this Agreement,
each party shall provide complete, timely and accurate information regarding its
requirements and all other data and information necessary for the performance by
the other party of its obligations hereunder and under the applicable Orders.

8.7.3 COMPANY shall, from time to time as reasonably required by AMDOCS, furnish
AMDOCS' personnel required to be at COMPANY's premises, at no charge to AMDOCS,
with space suitable for AMDOCS' needs and the following services: computer
terminals and associated peripherals including access to E-mail/Internet; a
communication line from COMPANY's data center to AMDOCS' development center in
St. Louis, Missouri; reasonable use of facsimile machine and telephone for
business purposes related to this Agreement only; and supplies, equipment and
consumables, and reasonable secretarial services in English, at COMPANY's normal
standards. All internal communications of AMDOCS using COMPANY's
e-mail/telephone/facsimile systems will be private, confidential and proprietary
to AMDOCS, and will be subject to COMPANY's standard policies and procedures.

<PAGE>   29

8.7.4 COMPANY shall grant the designated personnel of AMDOCS such access to the
premises and facilities of COMPANY as shall be reasonably necessary for the
performance of AMDOCS' obligations under this Agreement and the applicable
Orders.

8.7.5 AMDOCS shall indemnify, defend and hold harmless the COMPANY Indemnified
Parties (as defined in Section 8.18.1) harmless from and against all Claims (as
defined in Section 8.18.1) for personal injury or property damages resulting
from the wrongful or negligent acts of AMDOCS employees or agents (including
Authorized Subcontractors) while present at the premises and facilities of
COMPANY.

8.7.6 COMPANY is aware that it is required to have the necessary computer
equipment at its premises immediately upon the commencement of the provision of
services hereunder. COMPANY shall, therefore, obtain such computer systems and
provide AMDOCS upon the commencement of the Customization Services with
reasonable access to such equipment for the sole purpose of providing services
hereunder.

8.8      NO WAIVER

         No waiver of any rights arising under this Agreement shall be effective
         unless in writing and signed by the party against whom such waiver is
         sought to be enforced. No failure or delay by either party in
         exercising any right, power or remedy under this Agreement shall
         operate as a waiver of any such right, power or remedy and/or prejudice
         its rights to bring any action in respect thereof.

8.9      LIABILITY

8.9.1 IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR CLAIMS IN RESPECT OF OR
ARISING OUT OF THE PERFORMANCE OF ITS OBLIGATIONS HEREUNDER FOR ANY INDIRECT,
INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES (INCLUDING LOSS OF PROFITS,
REVENUE, DATA, OR USE), INCURRED BY THE OTHER PARTY OR BY ANY THIRD PARTY
WHETHER IN AN ACTION IN CONTRACT OR TORT, EVEN IF THAT PARTY OR ANY OTHER PERSON
HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

8.9.2 EXCEPT AS EXPRESSLY PROVIDED IN THIS AGREEMENT, THE SOLE LIABILITY OF
AMDOCS IN CASE OF ANY LOSS OR DAMAGE RESULTING FROM ANY ERROR OR DEFECT IN THE
LICENSED PRODUCT(S) OR THE CUSTOMIZED PRODUCTS OR FROM THE SERVICES PROVIDED BY
AMDOCS HEREUNDER THAT CAUSE ERRORS OR DEFECTS, WILL BE TO CORRECT, AS SOON AS IS
REASONABLY POSSIBLE, SUCH ERROR OR DEFECT IN ACCORDANCE WITH AMDOCS' WARRANTY OR
MAINTENANCE OBLIGATIONS. IN THE EVENT OF AN ERROR OR DEFECT THAT RENDERS THE
LICENSED PRODUCT(S) OR CUSTOMIZED PRODUCTS INOPERATIVE OR HAS A MATERIAL ADVERSE
EFFECT ON THE FUNCTIONING OF SUCH

<PAGE>   30

PRODUCT(S), AMDOCS SHALL, AS SOON AS REASONABLY POSSIBLE, COMMENCE DIAGNOSTIC
AND CORRECTIVE MEASURES, AND TAKE SUCH REMEDIAL MEASURES (INCLUDING, BUT NOT
LIMITED TO, TEMPORARY FIXES, EMERGENCY BYPASSES AND/OR WORKAROUNDS) AS MAY BE
REQUIRED TO CORRECT SUCH ERROR OR DEFECT, TO RENDER THE PRODUCT(S) OPERATIVE,
AND/OR TO ELIMINATE SUCH MATERIAL ADVERSE EFFECT.

8.9.3 COMPANY SHALL HOLD AMDOCS HARMLESS IN CASE OF ANY SUIT OR CLAIM BY ANY
THIRD PARTY ARISING FROM SPECIFICATIONS OR INSTRUCTIONS GIVEN BY COMPANY TO
AMDOCS RELATING TO THE CUSTOMIZATIONS.

8.9.4 EXCEPT FOR AMDOCS' LIABILITY UNDER SECTIONS 8.7, 8.14 AND 8.18, AMDOCS'
LIABILITY FOR DIRECT DAMAGES UNDER THIS AGREEMENT AND ANY ORDER HEREUNDER FOR
ANY CAUSE(S) WHATSOEVER SHALL NOT EXCEED ONE AND ONE-HALF MILLION DOLLARS
($1,500,000) PER SINGLE EVENT OR FIVE MILLION DOLLARS ($5,000,000) IN THE
AGGREGATE, EXCEPT AS OTHERWISE SPECIFIED IN AN ORDER.

8.10     CONFLICT OF INTEREST

         AMDOCS represents and warrants that no officer, employee or agent of
         COMPANY has been or will be employed, retained, paid a fee, or
         otherwise has received or will receive any personal compensation or
         consideration, by or from AMDOCS, or any of AMDOCS' officers, employees
         or agents, in connection with obtaining, arranging or negotiating this
         Agreement or other documents entered into, or executed in connection
         herewith.

8.11     FORCE MAJEURE

         Each party will be excused for any delay in its performance resulting
         from causes beyond its control which were not reasonably foreseeable on
         the date of signing this Agreement including Acts of God, war, riot,
         civil disorder, embargo, acts of authorities, fire, earthquake or flood
         and only to the extent such event actually delays such performance. The
         party so delayed must notify the other party of the occurrence and
         cessation of such an event to be able to rely upon the terms of this
         Section 8.11, unless the event itself prevents notice of occurrence
         being given, in which case it shall be given as soon as reasonably
         practicable. In no event, however, shall performance hereunder by
         either party be excused under this Section for a period in excess of
         three (3) months.

8.12     SEVERABILITY

         If any provision of this Agreement is determined to be invalid or
         unenforceable, such invalidity or unenforceability shall not invalidate
         or render unenforceable the

<PAGE>   31

         entire Agreement, but rather the entire Agreement shall be construed as
         if not containing the particular invalid or unenforceable provision or
         provisions, and the rights and obligations of AMDOCS and COMPANY shall
         be construed and enforced accordingly. In addition, the parties hereby
         agree to cooperate with each other to replace the invalid or
         unenforceable provision with a valid and enforceable one which will
         achieve the same economic result (to the maximum legal extent) as the
         provision determined to be invalid or unenforceable.

8.13     ENTIRE AGREEMENT AND CHANGES

         With the exception of the Confidentiality Agreement referred to in
         Section 8.5, the terms and conditions contained in this Agreement and
         in any Orders issued and accepted hereunder constitute the entire
         agreement between COMPANY and AMDOCS with respect to the subject matter
         hereof and supersede all prior oral and written quotations,
         communications, representations, agreements and understandings of the
         parties with respect to the subject matter hereof. This Agreement may
         not be altered, amended or modified except by a written instrument
         signed by a duly authorized representative of each party. Any
         pre-printed terms that may appear on any of AMDOCS' documents or any of
         COMPANY's documents which add to, vary from or conflict with the
         provisions of this Agreement shall be void.

8.14     TERMINATION

8.14.1 Either party may suspend performance and/or terminate this Agreement
immediately upon written notice at any time if:




         (i)   The other party shall file a petition seeking relief for itself
               under the bankruptcy laws of any jurisdiction;


         (ii)  An order for relief shall be entered against the other party
               under the bankruptcy laws of any jurisdiction, which order is not
               stayed; or upon the expiration of sixty (60) days after the
               filing of any involuntary bankruptcy petition against it without
               the petition being dismissed prior to that time; or


         (iii) The other party shall (a) make a general assignment for the
               benefit of its creditors; or (b) consent to the appointment of or
               taking possession by a receiver, liquidator, assignee, trustee,
               or custodian of all or a substantial part of its property; or (c)
               admit its insolvency or inability to pay its debts generally as
               they become due; or (d) fail generally to pay its debts as they
               become due; or (e) take any action (or suffer any action to be
               taken by its director or shareholders) looking to its dissolution
               or liquidation.

8.14.2 COMPANY may terminate for convenience any Order prior to Acceptance, or
any

<PAGE>   32

Support Services Order or Maintenance Order, upon thirty (30) days prior
written notice to AMDOCS. COMPANY shall pay to AMDOCS within thirty (30) days
following the effective date of such termination: (i) in the case of fixed price
Orders, the amounts due and payable under the payment installment immediately
following the date of notice of the termination, provided such notice is
received at least thirty (30) days prior to such payment installment, and (ii)
in the case of time and material Orders, all amounts due to AMDOCS under the
terminated Order until the effective date of such termination, plus, in the case
of this sub-Section (ii), a fee in an amount equal to the fees charged by AMDOCS
to COMPANY for such personnel during the month prior to termination.

8.14.3 COMPANY may, prior to Acceptance of a License or Customization Services
Order, or at any time for a Maintenance Services or Support Services Order,
provide notice of breach to AMDOCS if COMPANY reasonably determines that AMDOCS
has committed a material breach of an Order. Within fifteen days of receipt of
such notice, AMDOCS shall notify COMPANY in writing whether AMDOCS acknowledges
or disputes the occurrence of such material breach.

8.14.3.1 If AMDOCS provides notice to COMPANY acknowledging the occurrence of
such material breach and fails to cure the breach within thirty (30) days
thereafter, then COMPANY shall be entitled to Terminate the applicable Order.

8.14.3.2 If AMDOCS provides notice to COMPANY disputing the occurrence of such
material breach, then COMPANY shall be entitled to proceed with arbitration in
accordance with the provisions of Section 8.15.3. In the event that there is an
arbitral decision that AMDOCS has materially breached its obligations under the
applicable Order, and AMDOCS does not cure such breach within thirty (30) days
of the date of the arbitral decision, then COMPANY shall be entitled to
Terminate the applicable Order, without limiting any other rights and remedies
of COMPANY under this Agreement.

8.14.4 Upon Termination for breach, the following provisions will apply:

         a)    Each party shall return to the other party any information in
               tangible form obtained in connection with the relevant Terminated
               Order from the other party;

         b)    AMDOCS shall immediately cease performing work and incurring
               costs in connection with the relevant Terminated Order;

         c)    COMPANY's licenses under the relevant Terminated Order will be
               deemed immediately terminated;

         (d)   Within thirty (30) days of Termination, AMDOCS will return to
               COMPANY all License Fees actually received by AMDOCS for said
               terminated licenses; and

<PAGE>   33

         (e)   in the event that the Termination for breach consisted of AMDOCS'
               decision to cease work on any Order, then AMDOCS shall return to
               COMPANY all fees actually received by AMDOCS for licenses,
               services, and hardware under such Order within thirty (30) days
               of Termination.

8.14.5 Upon Termination for breach, COMPANY may exercise such remedies against
AMDOCS as are available under this Agreement, only, with no other remedies
available.

8.15      GOVERNING LAW, ESCALATION PROCEDURE AND ARBITRATION

8.15.1 The validity, performance, construction and effect of this Agreement
shall be governed by the laws of the State of Washington, without giving effect
to its choice-of-law rules.

8.15.2 COMPANY and AMDOCS will endeavor to resolve any controversy or claim
arising out of or relating to this Agreement or an Order through good faith
negotiations, as follows: If such a controversy or claim should arise, the
Project Managers of COMPANY and AMDOCS will attempt to resolve the matter within
nine (9) days of the matter being referred to them, or any other period agreed
upon by the parties; if the matter is not resolved by the project managers, it
will be referred to the head of COMPANY's IT Department and AMDOCS' Vice
President responsible for COMPANY; if the matter is not resolved by those
persons within nine (9) days of the matter being referred to them, or any other
period agreed upon by the parties, the matter will be referred to COMPANY's
President and AMDOCS' President for Customer Care and Billing Division
responsible for COMPANY/Senior Vice President. In the highly unlikely event that
those persons are unable to resolve the matter within nine (9) days of the
matter being referred to them, or any other period agreed upon, such matter will
be resolved exclusively by arbitration as provided in Section 8.15.3.

8.15.3 Any controversy or claim, whether based on contract, tort or other legal
theory (including, but not limited to, any claim of fraud or misrepresentation),
arising out or relating to this Agreement, including its interpretation,
performance, breach of or termination not resolved by good faith negotiations,
as provided in Section 8.15.2, shall be resolved exclusively by arbitration in
accordance with the following provisions:

         a)    The arbitration will be conducted in New York, New York by a sole
               arbitrator ("Arbitrator") in accordance with the rules of the
               American Arbitration Association (the "Rules"). The Arbitrator
               shall be appointed by agreement of the parties; in the event that
               the parties fail to agree upon the appointment of the Arbitrator
               within thirty (30) days after a notice of arbitration is given by
               either party to the other, then the Arbitrator shall be selected
               and appointed in accordance with the Rules. The arbitration will
               be governed by the United States Arbitration Act, 9 U.S.C.
               Section 1, et seq.

<PAGE>   34

         b)    Prior to his appointment, the Arbitrator shall be made aware of
               the terms of this Agreement and the relevant Order(s). The
               Arbitrator will be bound by the provisions of this Agreement
               including, but not limited to, the provisions of Section 3.5
               (Warranty), Section 8.9 (Liability) and Section 8.14
               (Termination). Prior to his appointment, selected Arbitrator
               shall be made aware of the terms of this Agreement and the
               relevant Order(s). Following his appointment, the Arbitrator
               shall set forth the schedule and timing of the arbitration
               proceedings.

         c)    The Arbitrator shall have the right to assess the costs incurred
               by either party against the losing party or in such manner as he
               deems just. That award rendered by such Arbitrator shall be final
               and binding.

         d)    Upon rendering an award or a decision, the Arbitrator shall set
               forth in writing the basis of such award or decision.
               Notwithstanding anything to the contrary, each party retains the
               right to request that a court of competent jurisdiction vacate
               the Arbitrator's award or decision on the grounds of the
               Arbitrator's failure to abide by the provisions of this Agreement
               or any applicable Order.

         e)    Judgment on the award or any other final or interim decision
               rendered by the Arbitrator may be entered, registered or filed
               for enforcement purposes in any court having jurisdiction
               thereof.

8.16     INDEPENDENT CONTRACTOR

         AMDOCS undertakes the furnishing of services and performance of its
         obligations under this Agreement as an independent contractor. AMDOCS'
         personnel participating in the performance of this Agreement shall
         remain AMDOCS' employees. There shall be no employer-employee
         relationship between AMDOCS' employees and COMPANY, and COMPANY's
         employees and AMDOCS.

8.17     ASSIGNMENT AND SUBCONTRACTS

8.17.1 Any assignment, sub-contract or other transfer of a party's rights or
obligations under this Agreement or under any Order issued hereunder requires
the prior written consent of the other party. Prior to any such assignments, the
assignee will be obliged to sign an undertaking to comply with all obligations

         b)    the participation of the Authorized Subcontractors shall not

         c)    AMDOCS' obligations under this Agreement and the Orders issued
               hereunder shall remain in full force and effect despite any act
               or omission of the Authorized Subcontractors; and

         d)    Specialist subcontractors shall not be assigned by AMDOCS to
               COMPANY's facilities without the prior written consent of
               COMPANY.


         The applicable terms of this Agreement (including, without limitation,
         those referred to in Section 8.19) shall also apply to the Authorized
         Subcontractors. The parties agree that the Authorized Subcontractors
         will require access to the premises and facilities of COMPANY for their
         participation in the performance of this Agreement and the Orders
         issued hereunder, and that if so requested by AMDOCS, COMPANY shall
         deal with the personnel of the Authorized Subcontractors and with any
         reasonable requests of the Authorized Subcontractors, in all respects,
         as if such personnel were the personnel, and such requests were the
         requests, of AMDOCS.

8.17.4 Subject to Section 8.5, Company may utilize employees or third party
consultants or contractors to perform modifications, enhancements, or
adjustments to the Licensed Products or Customized Products in a manner similar
to those provided by AMDOCS or an AMDOCS assignee.

connection with: (1) modifications made by COMPANY, (2) the instructions,
specifications or requirements supplied by COMPANY for the Customized Product or
any services to be provided by AMDOCS, or (3) COMPANY's combination of the
Licensed Products or the Customized Product with other products not supplied by
AMDOCS.
