CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS        Sprint Spectrum L.P.
(Unaudited)


The information in this Form 10-Q has been prepared according to  Securities and
Exchange Commission  rules and  regulations.  In our  opinion, the  consolidated
interim financial statements reflect all adjustments,  consisting only of normal
recurring accruals, needed to fairly present Sprint Spectrum L.P's consolidated
financial position, results of operations and cash flows.

Certain information and footnote disclosures  normally included in  consolidated
financial  statements  prepared  according  to  generally  accepted   accounting
principles have been condensed or  omitted.  As a result, you should  read these
financial statements  along with  Sprint  Spectrum's 1998  Form 10-K.  Operating
results  for  the  1999  year-to-date  period do not  necessarily  represent the
results that may be expected for the year ending December 31, 1999.

- --------------------------------------------------------------------------------
1.  PCS Restructuring
- --------------------------------------------------------------------------------

In November 1998, Sprint Corporation purchased the remaining ownership interests
in Sprint Spectrum Holding Company, L.P.--Sprint Spectrum's general partner--and
MinorCo,L.P.--Sprint Spectrum's limited partner--from Tele-Communications, Inc.,
Comcast  Corporation and Cox  Communications, Inc.  At that time, Sprint created
the  Sprint  PCS Group,  which consists of  Sprint's domestic  wireless personal
communication services (PCS) operations, including Sprint Spectrum.

- --------------------------------------------------------------------------------
2. Basis of Consolidation and Presentation
- --------------------------------------------------------------------------------

The consolidated financial  statements include the  accounts of Sprint  Spectrum
and its  subsidiaries.  Sprint  Spectrum is,  indirectly, a  wholly owned Sprint
subsidiary.

The  consolidated  financial  statements are  prepared using  generally accepted
accounting principles. These principles require management to make estimates and
assumptions  that affect  the reported  amounts of  assets and  liabilities, the
disclosure  of contingent  assets and liabilities, and the  reported  amounts of
revenues and expenses.  Actual results could differ from those estimates.

Certain prior-year amounts have been reclassified to conform to the current-year
presentation. These reclassifications had no effect on the results of operations
or partners' capital as previously reported.

- --------------------------------------------------------------------------------
3.  Long-term Debt
- --------------------------------------------------------------------------------

In the 1999 year-to-date period, Sprint  allocated $2.4 billion of senior  notes
with 5-year and 20-year maturities to Sprint Spectrum. These notes have interest
rates ranging from 7.6% to 8.8%.

In the 1999 first quarter, Sprint  Spectrum issued  notes payable  totaling $844
million to affiliates. The notes mature in 2006 and have interest rates based on
the London Inter-Bank Offered Rate plus 269 basis points.

In the 1999  first  quarter, Sprint  Spectrum  terminated  its revolving  credit
facilities and  repaid, prior to  scheduled maturities, the  related outstanding
balance of $1.7 billion.  These facilities had interest rates  ranging from 5.6%
to 6.3%.  These repayments resulted in a $33 million  extraordinary loss.  These
short-term  borrowings  were  repaid  with the long-term  financing  provided by
Sprint.

- --------------------------------------------------------------------------------
4. Litigation, Claims and Assessments
- --------------------------------------------------------------------------------

Various suits  arising in  the ordinary  course of business are  pending against
Sprint Spectrum.  Management  cannot predict  the final outcome of these actions
but believes they will not be material to the consolidated financial statements.

- --------------------------------------------------------------------------------
5.  Supplemental Cash Flows Information
- --------------------------------------------------------------------------------

Sprint Spectrum's cash paid for interest, net of  capitalized  interest, totaled
$224 million in the first  six months  of 1999 and $63 million in the  same 1998
period.

Sprint Spectrum's noncash activities included the following:

MANAGEMENT'S DISCUSSION AND ANALYSIS OF                     Sprint Spectrum L.P.
FINANCIAL CONDITION AND RESULTS OF OPERATIONS


- --------------------------------------------------------------------------------
General
- --------------------------------------------------------------------------------

In November 1998, Sprint Corporation purchased the remaining ownership interests
in Sprint Spectrum Holding Company, L.P.--Sprint Spectrum's general partner--and
MinorCo,L.P.--Sprint Spectrum's limited partner--from Tele-Communications, Inc.,
Comcast Corporation and Cox  Communications, Inc.  At that time,  Sprint created
the Sprint  PCS Group,  which consists  of Sprint's  domestic wireless  personal
communication services (PCS) operations, including Sprint Spectrum.

- --------------------------------------------------------------------------------
Forward-Looking Information
- --------------------------------------------------------------------------------

Sprint   Spectrum   includes   certain   estimates,   projections   and    other
forward-looking  statements in  its reports, in  presentations  to  analysts and
others, and in other publicly available material.  Future performance cannot  be
ensured.  Actual results may differ materially from those in the forward-looking
statements.  Some factors that could cause actual results to differ include:

     -   the effects of  vigorous  competition  in the markets in  which  Sprint
         Spectrum operates;
     -   the costs  and business  risks related  to entering  and expanding  new
         markets necessary to provide nationwide service and new services;
     -   the ability of Sprint Spectrum to grow its market presence;
     -   the impact of any  unusual items  resulting from ongoing evaluations of
         Sprint Spectrum's business strategies;
     -   unexpected results of litigation filed against Sprint Spectrum;
     -   the impact of the Year 2000 issue and any related noncompliance; and
     -   the possibility of one or more of the markets in which  Sprint Spectrum
         competes being impacted by changes in economic or other factors such as
         legal  and  regulatory  changes or  other external  factors over  which
         Sprint Spectrum has no control.

The words  "estimate,"  "project,"  "intend,"  "expect,"  "believe" and  similar
expressions are intended to identify forward-looking statements. Forward-looking
statements  are  found   throughout  "Management's  Discussion  and  Analysis of
Financial  Condition and  Results of  Operations".  The reader should not  place
undue reliance on forward-looking statements, which speak only as of the date of
this report.  Sprint Spectrum is not obligated to publicly release any revisions
to forward-looking statements to reflect events after the date of this report or
unforeseen events.

</TABLE>



The  wireless  industry  typically  generates a  significantly higher  number of
subscriber  additions  and  handset  sales  in  the fourth  quarter of each year
compared  to  the  remaining   quarters.   This  is due  to the  use  of  retail
distribution, which is dependent on the holiday shopping  season; the timing  of
new products  and service  introductions; and  aggressive  marketing  and  sales
promotions.

Sprint  Spectrum  markets its products through  multiple distribution  channels,
including its own retail stores as well as other retail outlets. Equipment sales
to one  retailer, and  the related  service revenues  generated by  such  sales,
accounted for  approximately 30% of net  operating revenues  in the 1999  second
quarter and year-to-date periods.

Net Operating Revenues

Net operating revenues include subscriber  revenues, roaming revenues  and sales
of  handsets  and accessory  equipment.  Subscriber revenues  consist of monthly
recurring charges  and usage charges.  Net operating  revenues increased 156% in
the 1999 second  quarter and 177% in the 1999 year-to-date  period from the same
1998 periods reflecting an increased customer base over the past 12 months.

Approximately 15% of the 1999  second quarter  and 20% of the  1999 year-to-date
net operating  revenues and 15% of the 1998  second quarter and year-to-date net
operating  revenues  were  from sales  of handsets and  accessories.  As part of
Sprint  Spectrum's marketing plans, handsets  are normally sold at prices  below
Sprint Spectrum's cost.

Operating Expenses

Costs of  services and  products mainly  includes handset  and accessory  costs,
interconnection costs, and switch and cell site expenses.  These costs increased
33% in the 1999 second quarter and 75% in the 1999 year-to-date period from  the
same 1998 periods  reflecting the significant  growth in customers  and expanded
market coverage, partly offset by a reduction in handset unit costs.

Selling, general and administrative (SG&A) expense  mainly  includes salary  and
benefit costs as well as marketing costs to promote products and services.  SG&A
expense  increased  54%  in  the  1999  second  quarter  and  40%  in  the  1999
year-to-date period from the same 1998 periods reflecting an expanded  workforce
to support subscriber growth and increased  marketing and  selling  costs.  SG&A
also includes costs  related  to Sprint Spectrum's  efforts to achieve Year 2000
compliance.

Depreciation and amortization expense consists of depreciation of network assets
and amortization  of  intangible  assets.  The  intangible  assets  include  PCS
licenses, which are amortized  over 40 years,  and  microwave  relocation costs,
which  are  amortized over  the  remaining  life of  the  related PCS  licenses.
Depreciation and amortization expense increased 17%  in the 1999 second  quarter
and 31% in the 1999 year-to-date  period from  the same 1998 periods  reflecting
depreciation of the network assets placed in service during 1999 and 1998.

Interest Expense
- --------------------------------------------------------------------------------

Interest expense increased 35% in the 1999  second quarter  and 41% in the  1999
year-to-date periods from the same 1998 periods reflecting increased borrowings.

- --------------------------------------------------------------------------------
Extraordinary Item
- --------------------------------------------------------------------------------

In the 1999  first quarter,  Sprint  Spectrum  terminated  its revolving  credit
facilities and  repaid, prior  to scheduled maturities, the related  outstanding
balance of $1.7 billion.  These facilities had  interest rates ranging from 5.6%
to 6.3%.  These repayments resulted in a $33 million  extraordinary loss.  These
short-term borrowings were repaid with long-term financing provided by Sprint.

- --------------------------------------------------------------------------------
Liquidity and Capital Resources
- --------------------------------------------------------------------------------

Sprint Spectrum's liquidity and capital resources are managed by Sprint.  Sprint
funds the  Sprint PCS Group's,  including  Sprint Spectrum's,  operating losses,
working capital and debt service requirements.

- --------------------------------------------------------------------------------
Year 2000 Issue
- --------------------------------------------------------------------------------

The "Year 2000" issue affects  Sprint  Spectrum's  installed  computer  systems,
network elements, software  applications, and other  business  systems that have
time-sensitive  programs  that may not properly  reflect or  recognize  the year
2000.  Because many computers and computer applications define dates by the last
two digits of the year, ''00'' may not be properly identified as  the year 2000.
This error could result in miscalculations  or system  failures.   The Year 2000
issue  may also  affect  the  systems  and  applications  of  Sprint  Spectrum's
customers, vendors, resellers or affiliates.

Sprint Spectrum  has completed  an  inventory  and  assessment  of its  computer
systems, network elements, software applications, products  and  other  business
systems.  Sprint Spectrum has  also  completed  the  renovation  of its computer
systems and other business  systems.  Substantially  all  of  Sprint  Spectrum's
software applications and network elements are renovated.  Testing  began in the
1999 first quarter and  is  forecasted  to  be  completed  by  year-end.  Sprint
Spectrum is using both internal and external resources to identify,  correct  or
reprogram, and test its systems for Year 2000 compliance.  It expects Year  2000
compliance for these critical systems to be achieved in 1999.

Sprint Spectrum is also contacting  others  with whom it  conducts  business  to
receive the proper warranties and assurances that those third parties, including
affiliates, are  or  will  be Year  2000  compliant.  Sprint Spectrum  relies on
third-party vendors for a significant  portion  of its  important  operating and
computer system functions and is highly dependent on those  third-party  vendors
to remediate and test network elements, computer systems, software  applications
and other business systems.  However, Sprint Spectrum is  reviewing test results
provided by its  vendors to  help  ensure  Year  2000  compliance.  In addition,
Sprint Spectrum uses publicly  available  services  that  are  acquired  without
contract, such as global positioning system timing signal, that may  be affected
by the Year 2000 issue.  While Sprint Spectrum believes these publicly available
systems will be Year 2000 compliant, it has  no  contractual or  other right  to
force compliance.

Sprint Spectrum incurred approximately $25 million from  inception through  June
1999 for its Year 2000 remediation program and  expects  to incur  approximately
$25 million through the remainder of 1999.  This program is  designed to  assure
the proper  functioning  of  critical  and  secondary  elements  for  Year  2000
compliance. When this program is fulfilled, Sprint Spectrum has a high degree of
confidence that elements within its control will function  through the  upcoming
date changes.  However, two risks remain: (1) the risk to Sprint Spectrum if its
Year 2000 program is not  fulfilled,  and (2) the risk  stemming  from  elements
vulnerable to the Year 2000 problem  which are beyond Sprint Spectrum's control.

If the Year 2000 program is not fulfilled in a timely manner by Sprint Spectrum,
or any of its affiliates or any significant third party does not fulfill its own
Year 2000 program in a timely manner, the Year 2000 issue could  have a material
adverse effect on Sprint Spectrum's operations.  Sprint Spectrum is  focusing on
identifying and addressing all aspects of its operations that may be affected by
the Year 2000 issue.

With regards to the second risk, Sprint Spectrum is evaluating events beyond its
control that could occur before and after the arrival  of the year 2000.  Sprint
Spectrum  is  reviewing  its  existing  disaster recovery  plans and  developing
additional contingency and  business  continuity plans  to prepare  for the year
2000.  Most of these were completed in the second quarter.  Sprint Spectrum will
implement, if necessary, appropriate contingency and  business continuity  plans
to mitigate to the extent possible the effects of any Year 2000 noncompliance.

Sprint Spectrum has begun to review the risks related  to a worst case  scenario
that could result from a Year 2000 related failure.   This scenario could result
in a temporary disruption to normal business operations and could  impact Sprint
Spectrum's financial performance.  Based upon the work completed to date, Sprint
Spectrum believes that such an occurrence is  unlikely.   Nevertheless,  certain
elements  related   to  the  Year   2000  readiness   of  suppliers,  utilities,
interconnecting carriers and customers are beyond Sprint Spectrum's control  and
could fail.  At this point, Sprint Spectrum does not believe that the failure of
such elements could cause a major breakdown within its normal operations.

accordance with Milestone 2 as set forth on Exhibit A1, within sixty (60) days
of the Effective Date, the Vendor must deliver to the Owner the Preliminary RF
Design for each of the System Areas in accordance with the requirements and
criteria set forth in Exhibit B1 and Schedule 1; provided that the Vendor agrees
                                                 -------- ----
to (i) provide Preliminary RF Designs (as set forth above) to the Owner for each
of the Milwaukee, Denver, Salt Lake and Spokane System Areas (as set forth on
Schedule 4) within sixty (60) days of the Effective Date unless, within fourteen
(14) days from delivery of the existing RF information relating to the above
listed four (4) System Areas from the Owner to the Vendor, the Vendor, after
careful consideration determines in good faith that such information or plans
need to be redesigned so that the Vendor may achieve such Milestone 2 (as set
forth in Exhibit A1) for such four (4) System Areas in accordance with Schedule
1 and the terms of this Contract, in which case the Vendor will receive an
additional twenty-one (21) days in which to deliver such Preliminary RF Designs
for such four (4) System Areas only (in no event will such time period from the
Effective Date exceed eighty-one (81) days for such four (4) System Areas) and
(ii) provide to the Owner such a Preliminary RF Design for the Detroit System
Area (as set forth on Schedule 4) within eighty-one (81) days of the Effective
Date.  The Vendor must provide the Owner with the applicable search rings for
each PCS System based upon the Preliminary RF Design within twenty (20) Business
Days of Milestone 2 (as set forth in Exhibit A1).  The Owner and the Vendor
agree to cooperate with each other to complete the RF Engineering and the Site
Acquisition.  The Owner must notify the Vendor of desired coverage areas, RF
Engineering parameters or other information or restrictions the Owner wishes to
be included in the Final RF Engineering Plan for each PCS System.  In accordance
with Exhibit B1, the Vendor will do the RF Engineering in each of the PCS
Systems and in connection therewith will use the parameters, information and
restrictions supplied by the Owner.  As part of the RF Engineering, the Vendor
will establish "search rings" in each of the PCS Systems that will specify areas
in which the Owner may proceed with Site Acquisition.

       (b)  In accordance with Exhibit B1 the Vendor, at its request, must be
kept informed of the progress made on ongoing Site Acquisition within the System
Areas.  As the Site Acquisition progresses, the Vendor agrees to regularly alter
the RF Engineering plan to determine a new search ring or rings to take into
account any changes or modifications requested by the Owner or otherwise
requested by the Owner due to the Owner's inability to acquire sufficient rights
to a location which could constitute a System Element Location in a timely or
economic manner.  When making changes to the RF Engineering plan the Vendor must
take into account the Site Acquisition already completed by the Owner.

                                                                              26

       (c)  Milestone 5 (as set forth in Exhibit A1) will be achieved in each
PCS System in accordance with this subsection 2.6(c); provided that for each PCS
                                                      -------- ----
System the appropriate MSCs have been installed by the Vendor in the Owner's
relevant Switch Sites within each such PCS System in accordance with subsection
2.6(d) below.  In accordance with the Project Milestones set forth on Exhibit A1
and the requirements and criteria set forth in Exhibit B1, within five (5) days
of the Owner achieving Site Acquisition Substantial Completion within any given
System Area (the "Final RF Review Period"), the Owner and the Vendor will use
their best efforts to agree on a final System Element Location count (the "Final
Site Count") and a final RF Engineering plan (the "Final RF Engineering Plan")
for such System Area upon which the PCS System for such System Area will be
built by the Vendor.  Failure of the Owner and the Vendor to reach satisfactory
agreement on a Final Site Count and/or a Final RF Engineering Plan for any given
System Area within the Final RF Review Period will automatically result in the
referral of any such disagreement to the most senior RF engineers of both the
Owner and the Vendor for their review and resolution within five (5) days after
the end of any such Final RF Review Period.  If the senior RF engineers fail to
resolve any such disagreement within the extended five (5) day resolution
period, the disagreement will automatically be referred for resolution in
accordance with subsection 23.1.  It is understood by the Parties that during
the period of any such disagreement and the resolution thereof in accordance
with the Contract, the Work on such PCS System, to the extent possible, will be
ongoing and that Substantial Completion on such PCS System cannot be achieved
without agreement by the Parties on a Final RF Engineering Plan and/or a Final
Site Count for such PCS System and/or System Area.

       (d)  The Vendor will install each of the MSCs in each of the Switch Sites
identified by the Owner in each PCS System within the System within sixty (60)
days of the Switch Site Ready Date; provided that (i) the Owner will have
                                    -------- ----
provided the Vendor with the MSC configuration engineering information at least
one hundred (100) days prior to the Switch Site Notice Date, for each such MSC,
such that the Vendor may actually perform the Owner's MSC configuration
engineering (other than the Switch Site layout configuration), (ii) the Owner
will have provided the Vendor with the applicable Switch Site description (in
appropriate detail) at least sixty (60) days prior to the Switch Site Notice
Date and (iii) as of the Switch Site Ready Date the applicable Switch Site will
have been made ready by the Owner such that the relevant MSC can in fact be
installed by the Vendor.  For the purposes hereof (i) the "Switch Site Ready
Date" means the date specified by the Owner as the date on which the Switch Site
will in fact be ready for MSC installation as communicated to the Vendor by the
Owner in the Owner's Switch Site Notice to the Vendor, (ii) the "Switch Site
Notice Date" will mean, as to any Switch Site Notice, the date on which such
notice was delivered to the Vendor by the Owner and (iii) the "Switch Site
Notice" will mean the notice provided to the Vendor by the Owner in sufficient
detail to describe the Switch Site so that the Vendor may reasonably engineer
the layout of the MSC configuration specifically for such Switch Site.  Nothing
contained herein will in any way limit the Vendor's obligation pursuant to the
terms of this Contract to do the MSC engineering and the RF Engineering in
accordance with the terms of this Contract.  Pursuant to this subsection 2.6(d)
in no event will the Owner provide the Vendor the Switch Site Notice more than
sixty (60) days later than the date the Owner delivers the Vendor the Build
Notice pursuant to subsection 2.7(a).

       2.7  Facilities Preparation Services and Installation.  (a)  For any
            ------------------------------------------------
given PCS System within the Initial System prior to Milestone 5 (as set forth on
Exhibit A1) for such PCS System the Owner (i) may, in its discretion, provide
notice to the Vendor when it has achieved Site Acquisition of at least fifty
(50) System Element Locations in any given PCS System or (ii) in any event, (if
the Owner hasn't already provided notice pursuant to clause (i) above) will
provide such notice to the Vendor when it has achieved Site Acquisition of at
least thirty percent (30%) of the System Element Locations in any given PCS
System (in either event, the "Build Notice").  The Build Notice calculation will
be based upon the Owner's reasonable estimate of System Element Locations within
or in connection with the Preliminary RF Design applicable to the PCS System in
which such Build Notice is issued to the Vendor.  The Build Notice for each PCS
System will also include the Owner's best forecast based upon information
available at such time (the "M5 Forecast") of when it expects to be able to
declare Site Acquisition Substantial Completion within such PCS System.  The
Owner understands that the Vendor will not be required to commence Facilities
Preparation Services and/or Installation in any given PCS System until and
unless it has received the applicable Build Notice pursuant to and in accordance
with this subsection 2.7.

       (b)  In accordance with the Project Milestones specified in Exhibit A and
the requirements and criteria of Exhibit B2, for each System Area the Vendor
must complete the Facilities Preparation Services for all System Element
Locations within such PCS System in accordance with the construction criteria
set forth in Exhibit E and the performance criteria set forth in Exhibit F no
later than ninety (90) days from the Owner/Vendor agreement on a Final Site
Count and a Final RF Engineering Plan for such System Area; provided that upon
                                                            -------- ----
the prior written request of the Vendor, the Owner may consent (which consent
will not be unreasonably withheld) to postpone Milestone 6 (as set forth in
Exhibit A1) with respect to any PCS System by not more than an additional sixty
(60) days in the event that more than ten percent (10%) of the System Element
Locations in such PCS System estimated as of the date of the Build Notice for
such PCS System have not been fully acquired by the Owner immediately prior to
the date on which Milestone 5 (as set forth in Exhibit A1) otherwise occurs in
such PCS System.  Pursuant to the Project Milestones the Vendor must complete
Installation of the Products for any given PCS System within thirty-two and one
half (32-1/2) days of its completion of the Facilities Preparation Services in
accordance with Milestone 6 (as set forth on Exhibit A1) for such PCS System
pursuant to the requirements and criteria set forth in Exhibit D and Exhibit F.

       2.8  Site Acquisition Modifications.  In the event that the Owner
            ------------------------------
determines that it is unlikely to achieve Site Acquisition Substantial
Completion for any PCS System in a timely and cost-effective manner, the Vendor
will modify certain performance criteria set forth in Exhibit F with respect to
such PCS System in the manner and to the degree that the Owner reasonably
specifies in writing to the Vendor in accordance with the terms of Exhibit B3.
In the event the Owner notifies the Vendor of a modification to the System
performance criteria for such PCS System pursuant to this subsection 2.8, such
modified criteria, including any such lower number of System Element Locations
that the Owner, in its sole discretion, deems at such time to be satisfactory so
as to constitute Site Acquisition Substantial Completion, will be deemed the
performance criteria and the System Element Location count

       (b)  Pursuant to and in accordance with the terms of Exhibits B3 and G,
BTS/BSC-MSC Interoperability must be demonstrated on or before December 1, 1996
(provided that such date will change to reflect the actual delay beyond December
 -------- ----
31, 1995 in the finalization of "Attachment A" to be attached to Exhibit G);

provided that in any event the requirements of this subsection 2.9(b) are a
- - - -------- ----
condition to the Vendor's Substantial Completion of the last PCS System within
the Initial System and Substantial Completion of such last PCS System will not
be deemed to have been achieved by the Vendor unless and until such
Interoperability will have been demonstrated in accordance with the criteria set
forth in Exhibit G; provided further that any delay in such Interoperability
                    -------- -------
which is not due substantially to the fault of the Vendor, in the reasonable
opinion of the Owner, will not be a delay pursuant to the terms of this
subsection 2.9(b).

       2.10  Certification.  The Vendor must coordinate its performance of the
             -------------
Services described in subsection 2.9 with the Engineering and design efforts
(including, without limitation, any and all RF Engineering and/or Site
Acquisition) of all Subcontractors, the Owner, the Other Vendors, any and all
supply and transportation requirements and all federal, state and local
authorities or agencies.  The Vendor will be fully knowledgeable about and will,
after reasonable review thereof, accept all Engineering, including, without
limitation, RF Engineering and design, irrespective of whether the Vendor, the
Other Vendors, the Owner or third parties such as the Subcontractors may furnish
such services.  All Engineering requiring certification must be certified by
professional engineers licensed or properly qualified to perform such
Engineering services in all appropriate jurisdictions if such certification is,
in the Owner's opinion, appropriate and reasonable under the circumstances.
This subsection 2.10 will not modify or restrict the Vendor's obligation and/or
right to provide the Services contracted for pursuant to the terms of this
Contract.

       2.11  Notice of Developments.  2.11.1  Vendor Developments.  The Vendor

must provide the Owner, through the NDAB or the Owner's vice president and/or
director of product development, with reasonable prior notice of any PCS Product
developments, innovations and/or technological advances (collectively "Vendor
Developments") relevant to the System prior to giving such notice to any other
Customer or otherwise making any such Vendor Development public within the
relevant marketplace; provided that the Vendor will not be obligated to provide
                      -------- ----
the Owner such notice before any other Customer if doing so would not be
reasonable under the circumstances and/or otherwise breach any contractual
obligation to any other Customer; provided further that any such notice pursuant
                                  -------- -------

proprietary to such other Customer of the Vendor.  For the purposes of this
subsection 2.11.1 the term "Vendor" includes the Vendor and its affiliates and
subsidiaries.

       2.11.2  Participation in Testing.  The Owner has the right, but not the
               ------------------------
obligation, to witness and/or participate in any initial testing and/or
application of any such Vendor Development (other than a Vendor Development
originated by another Customer which includes information which is proprietary
to such other Customer); provided that any such initial testing of Vendor
                         -------- ----
Developments will be subject to (i) scheduling as reasonably determined by the
Vendor, (ii) the qualification that the Owner's PCS System meets the technical

by the Vendor (or otherwise that the Owner is willing to update such PCS System
to meet such requirements), (iii) the Owner's acknowledgement that it will be
able to provide the resources necessary to implement the initial testing for
such Vendor Development, and (iv) the Owner and the Vendor executing a
verification office testing agreement that identifies the scope, terms, pricing,
responsibilities and schedule related to the initial testing of such Vendor
Development.  The Vendor must provide the Owner at least thirty (30) days' prior
notice of its intent to test any such Vendor Development and upon the Owner's
written request the Vendor will allow the Owner to participate in such testing
upon terms and in a testing environment reasonably acceptable to the Parties at
such time.  The Owner will make its Test-bed Laboratory and/or certain of its
PCS Systems (following Final Acceptance thereof) available to the Vendor for any
such testing in which the Owner has the right, and will have notified the Vendor
of its desire, to participate in pursuant to the terms of this subsection
2.11.2.  Where the Vendor and the Owner have agreed that the Owner's Test-bed
Laboratory or PCS System will be used as a test bed for Vendor Developments, the
Owner will not unreasonably withhold the Vendor's requests for other Customers
to observe the tests or to release results of the tests to other Customers;

provided that the Owner will have had reasonable prior notice that the Vendor
- - - -------- ----
would like to have other Customers observe such testing and that the Vendor will
remain liable in all respects pursuant to the terms of this Contract for the
protection of Proprietary Information in connection with any such testing.  The
length of the prior notice period described above may be shortened to under
thirty (30) days if necessary and appropriate under the circumstances, but in no

Location endangering life or property, the Vendor must take such action as may
be reasonable and necessary to prevent, avoid or mitigate injury, damage or loss
and will, as soon as possible, report any such incidents, including the Vendor's
response thereto, to the Owner.  Whenever, in the reasonable opinion of the
Owner, the Vendor has failed to take sufficient precautions for the safety of
the public or the protection of the Work or of structures or property on or
adjacent to any Vendor-Controlled Location, creating, in the reasonable opinion
of the Owner, an emergency requiring immediate action, then the Owner, after
having given reasonable prior notice to the Vendor, may cause such sufficient
precautions to be taken or itself provide such protection.  The taking or
provision of any such precautions or protection by the Owner or its agents or
representatives will be for the account of the Vendor and the Vendor must
reimburse the Owner for the cost thereof.

       2.14  Right of Inspection.  The Owner, the parties providing financing in
             -------------------

     (g)  Technical assistance and support must be provided for the purpose of
resolving non-emergency problems defined below as "P1 Major Condition", "P2
Significant Problem" and "P3 Minor Problem" which are reported to the Vendor.

                         (i)   P1 Major Condition (this roughly corresponds to
               Severity 1 Conditions in the Vendor's ISO 9001 documentation)
               means any non-emergency failure of specific features or functions
               of the System, any PCS System or any Product that restricts its
               operations, but does not render the System, any PCS System or any
               Product inoperable, impact traffic capacity or coverage or
               require significant manual intervention for the System, any PCS
               System or any Product to operate properly and in
<PAGE>

                                                                              40

               accordance with its applicable Specifications.  These events will
               include loss of diagnostic capabilities and loss of reporting
               functions.  The Vendor will use all reasonable efforts to use by-
               pass or work-around procedures to alleviate such P1 Major
               Condition until it is corrected and, upon mutual agreement of the
               Parties, the Vendor will resolve such P1 Major Condition during
               the next available scheduled Software Upgrade or Equipment
               Upgrade.

                         (ii)   P2 Significant Problem (this roughly corresponds
               to Severity 2 Conditions in the Vendor's ISO 9001 documentation)
               means any non-emergency, intermittently occurring problem related
               to specific primary functions or features or any inoperable
               secondary functions that do not have a significant adverse effect
               on the overall performance of the System, any PCS System or any
               Product.  The Vendor will undertake appropriate and reasonable
               efforts to correct such P2 Significant Problem.

                         (iii)    P3 Minor Problem (this roughly corresponds to
               Severity 3 Conditions in the Vendor's ISO 9001 documentation)
               means any non-emergency problem that does not affect the
               performance or functions of the System, any PCS System or any
               Product, and, despite such problem, the System, any PCS System or
               any Product is fully operable without restrictions. Such P3 Minor
               Problems may include documentation inaccuracies, cosmetics, minor
               requests for changes or maintenance requests.  The Vendor will
               undertake appropriate and reasonable efforts to correct such P3
               Minor Problem.

     (h)  Should a non-emergency problem remain unresolved for the period or
periods of time set forth below following referral to the Vendor by the Owner,
such problem must be reported to the levels of management set forth below to
ensure all available resources necessary to correct such problem will be
committed to address such problem pursuant to the following:

     Non-emergency problems referred to the Vendor as a CSR will be resolved
based upon the priority assigned to them as determined by the Owner or as
mutually agreed by the Parties and, to the extent reasonably possible, will be
incorporated into the next scheduled Software release.

     2.26.4  ETA and CSR.  In the event that emergency technical support
             -----------
provided from the Vendor's technical support center is not sufficient to resolve
an E1 Emergency Condition, the Vendor must send a technically qualified person
or persons to the site of such emergency condition or problem to assist the
Owner's employees in solving such condition or problem.  The Vendor's
technically qualified person or persons must be on-site as soon as possible, but
in no event more than twenty-four (24) hours after notification to the Vendor by
the Owner, or at such later time as may be mutually agreed on by the Parties.
In the event that emergency technical support provided from the Vendor's
technical support center is not sufficient to resolve an E2 Emergency Condition,
then the Parties will mutually agree to a desired course of action, which may
include requiring the Vendor to send a technically qualified person or persons
to the site of such emergency.

     A CSR may be submitted by the Owner to request a repair or work-around of
an emergency condition or repair of a non-emergency problem, or to request a
Software Upgrade or an Equipment Upgrade or other Software or Equipment
operational enhancement.  The Owner's CSRs will define the condition or problem
and state whether the Owner considers the CSR to be for a Software Upgrade or an
Equipment Upgrade or other Software or Equipment operational enhancement.
Changes to the System or any PCS System resulting from any CSR must be fully
tested and accepted in accordance with the Specifications.  The Vendor must
respond to the submission of a CSR by the Owner within five (5) Business Days,
acknowledging receipt of the CSR.  Within thirty (30) days of receipt of the
CSR, the Vendor will respond to the CSR summarizing the Vendor's intended
actions to handle the CSR.  A CSR may result in System fixes or enhancements, or
in Product modifications reasonably acceptable to the Owner.

     Notwithstanding the above, no event, lack of functionality or failure of
the Test-bed Laboratory will be assigned as an E1 Emergency Condition or E2
Emergency Condition.  Any such event, lack of functionality or failure
applicable to the Test-bed Laboratory, which would otherwise be assigned such a
category in accordance with the definitions above, will be assigned a P1 Major
Condition.

     2.27  Supply of Additional Products.  During the Initial Term of this
           -----------------------------
Contract and for a period of three (3) years thereafter, the Vendor will make
available for purchase by the Owner, on applicable terms and conditions set
forth in this Contract or as otherwise mutually agreed between the Parties, PCS
Products to enable the Owner to expand the System and/or any PCS System and/or
any part thereof, which Products will provide equivalent functionality for and
will be compatible with the System or any such PCS System at such time.  Nothing
herein will be deemed to prohibit the Vendor from designating any specific PCS
Products as Discontinued Products in accordance with Section 10 of this
Contract.
<PAGE>

                                                                              42

     2.28  Review of Contract.  The Vendor has examined in detail and carefully
           ------------------
studied and compared the Contract with all other information furnished by the
Owner and has promptly reported to the Owner any material errors,
inconsistencies or omissions so discovered or discovered by any of the
Subcontractors.  The Vendor will not prosecute any Major Portion of the Work
knowing that it involves a material error, inconsistency or omission in the
Contract without prior written notice to and approval by the Owner.  If for any
reason the Vendor violates this subsection 2.28, the Vendor will, in addition to
being subject to any other remedies of the Owner, assume responsibility for such
violation and, in such case, will be deemed to have waived any claims for an
adjustment in any of the Specifications and/or System Standards which results
directly from any such error, inconsistency or omission.  This subsection 2.28
does not, nor will be deemed to, in any manner limit the terms of subsection
2.39.

     2.29  Licenses, Permits and Approvals.  Except as otherwise provided for
           -------------------------------
herein with respect to Site Acquisition, Microwave Relocation and Network
Interconnection, any Applicable Permits (in connection with the Vendor's Work)
required by any Government Entity relating to the manufacture, importation,
safety or use of the Products, the System or any PCS System throughout the
United States or in any state or any political sub-division thereof will be the
sole responsibility of the Vendor.  Prior to the commencement of any Work and/or
other activities by the Vendor or any of its Subcontractors in connection with
or pursuant to this Contract, upon request of the Owner the Vendor will furnish
the Owner with evidence that such Applicable Permits have been obtained and are
in full force and effect to the extent that Applicable Permits are necessary for
the commencement or undertaking of such activities, and from time to time
thereafter the Vendor, upon the reasonable request of the Owner, will provide
such further evidence as the Owner will deem reasonably necessary.

     2.30  Eligibility under Applicable Laws and Applicable Permits.  The Vendor
           --------------------------------------------------------
will be responsible for ensuring that the Vendor and its Subcontractors are and
remain eligible under all Applicable Laws and Applicable Permits to perform the
Work under this Contract in the various jurisdictions involved.

     2.31  Customs Approvals.  The Owner agrees to reasonably assist, so long as
           -----------------
such assistance will not involve the incurrence of any costs or expenses by the
Owner, the Vendor to obtain and maintain (i) Applicable Permits for importation
into the Products on a duty and customs free basis and (ii) entry or work
permits, visas or authorizations required for personnel engaged by the Vendor to
perform Work under this Contract.

     2.32  Owner Participation.  In addition to the right of observation
           -------------------
contained in subsection 9.4 hereof, the Owner will be entitled to participate in
the Vendor's research and development activities (subject to the reasonable
acceptance of the Vendor) and product development and testing activities
pursuant to this Contract (other than research and development activities
originated by another Customer which is proprietary to such other Customer);

provided that such observation and participation will not affect the Vendor's
- - - --------
responsibilities and warranties hereunder and will not otherwise interfere with
the Vendor's research and development activities.  Nothing contained in this
subsection 2.32 purports to grant the Owner rights to the Vendor's research and
development other than such rights
<PAGE>

                                                                              43

otherwise granted to the Owner pursuant to the terms of this Contract or as
otherwise mutually agreed by the Parties at such time.

     2.33  New Development Advisory Board.  In order to accommodate the Owner's
           ------------------------------
participation pursuant to this Contract, including, without limitation, pursuant
to subsections 2.11 and 2.32, the Owner and the Vendor will establish an NDAB
within sixty (60) days of the Effective Date.  The purpose of the NDAB will be
to review the development requirements and high level development milestones, to
ensure that the Vendor understands the Owner's requirements for each PCS System,
the System and/or any extensions thereto including, without limitation, any
subsequent Products and/or enhancements.  The NDAB will provide an executive
forum to discuss product ideas, Owner requirements and its recommended
development prioritization for improved infrastructure-based subscriber features
and System features, functions and capabilities.  The focus of the NDAB will be
on System features and services, new PCS Products, System enhancements, critical
operational issues, future developments beyond CDMA cellular without the need
for System additions and on such other matters as the Parties mutually agree
upon from time to time.

     2.34  Market Development Manager.  The Vendor will provide a market
           --------------------------
development manager to coordinate the efforts of the Vendor in meeting its
obligations relating to the NDAB who will specifically focus on new Products,
CDMA services and features.  Such market development manager must be
knowledgeable in CDMA technology and the Owner's System and must work closely,
and on a regularly scheduled basis, with the Owner's senior engineering and
marketing personnel on feature development, feature roll-out, future road maps
for PCS Products, and any other marketing aspect of providing PCS that the Owner
believes is beneficial to the System and/or any PCS System at such time.  The
Vendor's market development manager and the manager's staff will serve as the
Owner's direct liaison with the Vendor to ensure that the Vendor's product
development teams are focusing on the Owner's priorities as described to the
Vendor by the Owner from time to time either through the NDAB or by any other
means acceptable to the Parties.  Nothing contained in this subsection 2.34 will
in any way limit and/or modify the Owner's ability to enforce its rights under
this Contract or to otherwise maintain contacts with the Vendor in any other way
it sees fit.

     2.35  Further Assurances.  The Vendor will execute and deliver all further
           ------------------
instruments and documents, and take all further action, including, but not
limited to, assisting the Owner in filing notices of completion with the
appropriate state and local lien recording offices, that may be necessary or
that the Owner may reasonably request in order to enable the Vendor to complete
performance of the Work or to effectuate the purposes or intent of this
Contract.

     2.36  Liens and Other Encumbrances.  (a)  In consideration of the mutual
           ----------------------------
undertakings herein and other good and valuable consideration the receipt and
sufficiency of which is hereby acknowledged, the Vendor:

          (i) covenants and agrees to protect and keep free the System and/or
     any PCS System and any and all interests and estates therein, and all
     improvements and
<PAGE>

                                                                              44

     materials now or hereafter placed thereon under the terms of this Contract,
     from any and all claims, liens, charges or encumbrances of the nature of
     mechanics, labor or materialmen liens or otherwise arising out of or in
     connection with performance by any Subcontractor, including services or
     furnishing of any materials hereunder, and to promptly have any such lien
     released by bond or otherwise;

          (ii) give notice of this subsection 2.36 to each Subcontractor before
     such Subcontractor furnishes any labor or materials for the System and/or
     any PCS System; and

          (iii)    make any and all filings reasonably requested by the Owner in
     order that the Owner may take advantage of the relevant local mechanics'
     lien waiver procedures with respect to mechanics' liens of any such
     Subcontractor.

     (b)  If any laborers', materialmen's, mechanics', or other similar lien or
claim thereof is filed by any Subcontractor, the Vendor will cause such lien to
be satisfied or otherwise discharged, or will file a bond in form and substance
satisfactory to the Owner in lieu thereof within ten (10) days of the Vendor's
receipt of notice of such filing.  If any such lien is filed or otherwise
imposed, and the Vendor does not cause such lien to be released and discharged
forthwith, or file a bond in lieu thereof, then, without limiting the Owner's
other available remedies, the Owner has the right, but not the obligation, to
pay all sums necessary to obtain such release and discharge or otherwise cause
the lien to be removed or bonded to the Owner's satisfaction from funds retained
from any payment then due or thereafter to become due to the Vendor.

     (c)  The Owner reserves the right to post or place within the System and/or
any PCS System notices of non-responsibility or to do any other act required by
Applicable Law, to exempt the Owner and the System from any liability to third
parties by reason of any work or improvements to be performed or furnished
hereunder; provided that failure by the Owner to do so will not release or
           -------- ----
discharge the Vendor from any of its obligations hereunder.

     2.37  Forecasting and Ordering.  Throughout the Term of this Contract, on a
           ------------------------
monthly basis commencing on the Effective Date, the Owner will provide the
Vendor with rolling twelve-month forecasts of its ongoing Product and Service
requirements.  Such forecasts will, to the extent applicable, include, but not
be limited to, the Owner's Site Acquisition, Switch Site Ready Date, Network
Interconnection and Microwave Relocation progress to such date.  Upon the review
and reasonable acceptance of such forecasts by the Vendor pursuant to the terms
of this Contract, the Owner will have the right, but not the obligation, to
confirm to the Vendor its orders for the Products and Services set forth in such
forecasts pursuant to the Owner's delivery to the Vendor of formal written
orders specifying the Products and/or Services to be purchased in connection
with the terms of this Contract.  The Vendor's obligation to deliver in
accordance with accepted forecasts will be subject to receipt of the Owner's
orders in accordance with the applicable ordering procedures.  If the Owner
fails to deliver any forecast pursuant to this subsection 2.37 for any reason,
the Vendor will be responsible for asking the Owner to actually deliver such
forecast to the extent it requires such forecast at such time.

                                                                              45

     2.38  Microwave Relocation; Network Interconnection.  (a)  The Vendor will
           ---------------------------------------------
not be responsible for Microwave Relocation within the System.  Unless otherwise
waived by the Owner, however, completion of Microwave Relocation in any given
System Area will be a prerequisite to the commencement of the Substantial
Completion testing to be performed by the Vendor in accordance with Exhibit B3
in such System Area.  The Owner may at its option choose instead to modify the
System performance criteria as set forth in Exhibit F by way of a Change Order
in order to account for the failure to fully and/or satisfactorily complete
Microwave Relocation in any such System Area such that Substantial Completion
testing in accordance with the requirements of Exhibit B3 may proceed.
Notwithstanding anything stated herein to the contrary (other than clause (b)
below), the Owner's failure and/or inability to fully complete Microwave
Relocation in any such System Area within twelve (12) months of Milestone 6 (as
set forth in Exhibit A1) (the "Microwave Delay Period") will entitle the Vendor
to otherwise commence Substantial Completion testing (as deemed applicable and
appropriate pursuant to good faith mutual agreement between the Parties at such
time) for the PCS System in such System Area in accordance with Exhibit B3.
Pursuant to the requirements of Exhibits A1, B1 and B3 with respect to any PCS
System within the System the Owner may, upon the prior written request of the
Vendor, consent (such consent not to be unreasonably withheld) to extend the
scheduling of the Vendor's Substantial Completion testing by not more than an
additional sixty (60) days pursuant to Milestone 8 in the event that more than
ten percent (10%) of the System Element Sites in such PCS System as set forth in
the Final Site Count for such PCS System require Vendor optimization pursuant to
Exhibit B1 that was otherwise delayed due to incomplete Microwave Relocation in
such PCS System immediately prior to the date scheduled for Substantial
Completion testing pursuant to Milestone 8 (as set forth on Exhibit A1).

     (b)  The Vendor will not be responsible for Network Interconnection within
the System.  In any given System Area, completion of Network Interconnection in
such System Area at least sixty (60) days (or as otherwise mutually agreed
between the Parties at such time) prior to Milestone 7 (as set forth on Exhibit
A1) will be a prerequisite to the Vendor's obligation pursuant to the terms of
this Contract to successfully achieve Milestone 7 (as set forth in Exhibit A1)
in such System Area.

     2.39  Vendor To Inform Itself Fully; Waiver of Defense.  (a)  The Vendor
           ------------------------------------------------
will be deemed to have notice of and to have fully examined and approved the
Specifications and all other documents referred to herein, and all drawings,
specifications, schedules, terms and conditions of this Contract, regulations
and other information in relation to this Contract and/or any amendments,
modifications or supplements thereto at any time on or after the Effective Date
and to have fully examined, understood and satisfied itself as to all
information of which the Vendor is aware or should have been aware and which is
relevant as to the risks, contingencies and other circumstances which could
affect this Contract and in particular the installation of the System, any PCS
System or any part thereof.  The Owner, its directors, officers, employees and
agents and all of them have no liability in law or equity or in contract or in
tort with respect to any such specifications, drawings, information, risks,
contingencies or other circumstances.
<PAGE>

                                                                              46

     (b) The fact that the Owner may have prepared or taken part in the
preparation of Specifications, documents, drawings, Engineering, designs,
specifications, schedules, terms or conditions, or may have designated
particular types of Products and/or Services to be furnished hereunder or
designated particular manufacturers or suppliers of Products or Services, or may
have taken part in the designation of any particular Subcontractor(s) or
subcontractor(s), or given vetoes or approvals with respect to the Work, or
otherwise become involved in the Work, will not give rise to any claim by the
Vendor or any Subcontractor or any defense to any warranty or other claims
asserted against the Vendor or any Subcontractor to the extent that any such
claim or defense arises out of any specifications, drawings, documents, or other
information, which the Vendor is deemed to have had notice of pursuant to
subsection 2.39(a) above and with respect to any such information arising after
the Effective Date which the Vendor had a reasonable opportunity to review.

     2.40  CMI/HIC.  From time to time throughout the Term of this Contract the
           -------
Parties may mutually agree as to the incorporation and integration of CMI/HIC
into the System in accordance with Exhibit D.

     2.41  Site Acquisition Delay Testing.  In any given System Area within the
           ------------------------------
Initial System, in the event Site Acquisition Substantial Completion is delayed
more than one hundred and fifty (150) days beyond the forecasted date for Site
Acquisition Substantial Completion as set forth in the M5 Forecast (the "Site
Acquisition Delay Period") provided to the Vendor with the Build Notice
applicable to such System Area due solely to the Owner's inability to achieve
sufficient Site Acquisition in such System Area, the Vendor will have the right,
but not the obligation, to commence Substantial Completion testing (as deemed
applicable and appropriate pursuant to good faith mutual agreement between the
Parties at such time but in any event to be completed within thirty (30) days of
such commencement) for that portion of the otherwise incomplete PCS System in
which the Vendor has (i) completed all applicable Facilities Preparation
Services and (ii) fully Installed, to the extent possible at such time, all such
Products to be Installed by the Vendor or its Subcontractors on otherwise fully
constructed  System Element Locations within such PCS System.  Subject to
Section 6, in the event the Vendor successfully completes such modified
Substantial Completion testing for such Installed portion of such otherwise
incomplete PCS System pursuant to and in accordance with this subsection 2.41
and Exhibit B3, the Vendor will be entitled to such portion of the payments that
otherwise would be made by the Owner pursuant to subsection 6.3(b) as applicable
only to those Services and Products actually provided by the Vendor pursuant to
and in accordance with the terms of this Contract in such portion of the
otherwise incomplete PCS System that was subject to testing pursuant to this
subsection 2.41.  Nothing contained herein to the contrary will in any way
modify the Vendor's obligations as to the completion and testing of the
remaining portion of such PCS System pursuant to and in accordance with the
terms of this Contract, including but not limited to the Project Milestones set
forth in Exhibit A1.  Nothing contained herein to the contrary will in any way
require the Owner to pay the Vendor amounts already paid or otherwise provided
for pursuant to any other provision of this Contract.

<PAGE>

                                                                              47

     3.1  Additional Affiliates.  On a quarterly basis commencing on the
          ---------------------
Effective Date and during the term of this Contract, the Owner may, upon fifteen
(15) days' prior written notice to the Vendor, designate any Person who has been
licensed to use PCS in the United States which is not an Initial Affiliate as an
"Additional Affiliate"; provided that the Vendor will have a reasonable
                        -------- ----
opportunity to review and approve such designation, such approval not to be
unreasonably withheld, based upon (i) reasonable credit criteria within the
context of the PCS industry, (ii) the fact that such proposed Additional
Affiliate has not in the past materially breached prior material agreements with
the Vendor, (iii) the fact that the proposed Additional Affiliate is not, at the
time of such determination, a direct competitor to the Vendor in the wireless
telecommunications business and (iv) the fact that the proposed Additional
Affiliate is not, at the time of such determination, otherwise engaged with the
Vendor in a material agreement for the purchase and/or supply of PCS CDMA
wireless technology; and provided, further, that (x) the Owner, any Partner or
                         --------  -------
any Initial Affiliate has at least a ten percent (10%) equity ownership in such
Person, (y) such Person is controlled by or under the common control with the
Owner, any Partner or any Initial Affiliate or (z) there exists between the
Owner and such Person an Additional Affiliate Arrangement.

     3.2  Agreements with Initial Affiliates.  During the term of this Contract,
          ----------------------------------
the Owner will have the right, but not the obligation, to require that the
Vendor enter into separate agreements with any Initial Affiliate designated by
the Owner (each, an "Initial Affiliate Agreement") for the supply of Products
and Services on similar terms and conditions as those set forth herein that
relate to the initial build-out of the Initial System as set forth on Schedule
4; provided that the Vendor will not be required to include in any Initial
   -------- ----
Affiliate Agreement any provisions substantially similar to those set forth in
subsections 2.3(a), 2.5, 2.23 (but only to the extent of the specific amounts
set forth in such subsection 2.23), 3.1, 3.3, 11.7, 15.1, 21.1, 24.1 and 27.5;
and provided further that after the date on which Final Acceptance of the last
    -------- -------
PCS System to reach Final Acceptance has occurred, Initial Affiliate Agreements
(whether or not executed prior to such date) need not contain or retain
substantially the same terms and conditions as those set forth herein, except
for those terms and conditions related to pricing and warranties as are then
available to the Owner pursuant to this Contract.  Any Initial Affiliate that
enters into an Initial Affiliate Agreement with the Vendor will have the right
to choose among the Products and Services offered to the Owner under this
Contract solely for use within the Nationwide Network.

     3.3  Agreements with Additional Affiliates.  During the term of this
          -------------------------------------
Contract, the Owner will have the right, but not the obligation, to require that
the Vendor enter into separate agreements with any Additional Affiliate
designated by the Owner (each, an "Additional Affiliate Agreement") for the
supply of Products and Services at similar price and warranty terms as are then
available to the Owner pursuant to the terms of this Contract.  The Vendor must
enter into good faith negotiations for the establishment of such Additional
Affiliate Agreements with any such Additional Affiliate promptly upon the
designation of such Additional Affiliate by the Owner and upon notice to the
Vendor that such Additional Affiliate desires to enter into an Additional
Affiliate Agreement.  Any Additional Affiliate that enters into an Additional
Affiliate Agreement with the Vendor will have the right to choose among the
Products and Services offered to the Owner under this Contract solely for use
within the Nationwide Network.

     3.4  Affiliate Rights.  Notwithstanding anything herein contained to the
          ----------------
contrary, Affiliates will not be deemed third party beneficiaries to this
Contract or otherwise have any rights hereunder.  Only the Owner may designate a
Person as an Affiliate in accordance with the terms of this Section 3 and only
the Owner has the right and/or the ability to enforce any rights hereunder
against the Vendor.


     SECTION 4  SUBCONTRACTORS

     4.1  Subcontractors.  The Vendor will select Subcontractors in connection
          --------------
with the performance of the Work such that all Products and Services provided by
any such Subcontractors meet the System Standards and reliability and
performance requirements set forth in this Contract.  Regardless of whether or
not the Vendor obtains approval from the Owner of a Subcontractor or whether the
Vendor uses a Subcontractor recommended by the Owner, use by the Vendor of a
Subcontractor will not, under any circumstances:  (i) give rise to any claim by
the Vendor against the Owner if such Subcontractor breaches its subcontract or
contract with the Vendor; (ii) give rise to any claim by such Subcontractor
against the Owner; (iii) create any contractual obligation by the Owner to the
Subcontractor; (iv) give rise to a waiver by the Owner of its rights to reject
any Defects or Deficiencies or Defective Work; or (v) in any way release the
Vendor from being solely responsible to the Owner for the Work to be performed
under this Contract.

     4.2  The Vendor's Liability.  The Vendor is the general contractor for the
          ----------------------
Work and remains responsible for all of its obligations under this Contract,
including the Work, regardless of whether a subcontract or supply agreement is
made or whether the Vendor relies upon any Subcontractor to any extent.  The
Vendor's use of Subcontractors for any of the Work will in no way increase the
Vendor's rights or diminish the Vendor's liabilities to the Owner with respect
to this Contract, and in all events, except as otherwise expressly provided for
herein, the Vendor's rights and liabilities hereunder with respect to the Owner
will be as though the Vendor had itself performed such Work.  The Vendor will be
liable for any delays caused by any Subcontractor as if such delays were caused
by the Vendor.

     4.3  No Effect of Inconsistent Terms in Subcontracts.  The terms of this
          -----------------------------------------------
Contract will in all events be binding upon the Vendor regardless of and without
regard to the existence of any inconsistent terms in any agreement between the
Vendor and any Subcontractor whether or not and without regard to the fact that
the Owner may have directly and/or indirectly had notice of any such
inconsistent term.

     4.4  Assignability of Subcontracts to Owner.  Each agreement between the
          --------------------------------------
Vendor and a Subcontractor must contain a provision stating that, in the event
that the Vendor is terminated for cause, convenience, abandonment of this
Contract or otherwise, (i) each Subcontractor will continue its portion of the
Work as may be requested by the Owner and (ii) such agreement permits assignment
thereof without penalty to the Owner and, in order to create security interests,
to the Other Vendors, in either case at the option of the Owner and for the same
price and under the same terms and conditions as originally specified in such
Subcontractor's agreement with the Vendor.

     4.5  Removal of Subcontractor or Subcontractor's Personnel.  The Owner has
          -----------------------------------------------------
the right at any time to require removal of a Subcontractor and/or any of a
Subcontractor's personnel from Work on the System upon reasonable grounds and
reasonable prior notice to the Vendor.  The exercise of such right by the Owner
will have no effect on the provisions of subsections 4.1 and 4.2.

     4.6  Subcontractor Insurance.  The Vendor must require its Subcontractors
          -----------------------
to obtain, maintain and keep in force during the time they are engaged in
providing Products and Services hereunder adequate insurance coverage consistent
with Section 18 and Schedule 6 (provided that the maintenance of any such
Subcontractor insurance will not relieve the Vendor of its other obligations
pursuant to Section 18 and Schedule 6).  The Vendor will, upon the Owner's
request, furnish the Owner with evidence of such insurance in form and substance
reasonably satisfactory to the Owner.  All such insurance will be subject to the
Owner's approval.  All Subcontractors must be of bondable financial condition.
Nothing herein will be deemed to bar the Vendor or any Subcontractor from
obtaining such insurance on a project basis for each of the Subcontractors
participating in such project.

     4.7  Review and Approval not Relief of Vendor Liability.  Any inspection,
          --------------------------------------------------
review or approval by the Owner permitted under this Contract of any portion of
the Work by the Vendor or any Subcontractor will not relieve the Vendor of any
duties, liabilities or obligations under this Contract, but nothing contained in
this subsection 4.7 will be deemed a bar of any waiver given by the Owner to the
Vendor pursuant to and in accordance with the terms of this Contract.

     4.8  Vendor Warranties.  Except as otherwise expressly provided in Section
          -----------------
17, the warranties of the Vendor pursuant to Section 17 will be deemed to
apply to all Work performed by any Subcontractor as though the Vendor had itself
performed such Work.  Except as otherwise specifically provided in Section 17,
the Parties agree that such warranties will not be enforceable merely on a
"pass-through" basis.    The Owner may, but will not be obligated to, enforce
such warranties of any Subcontractor to the extent that the Owner determines
that the Vendor is not paying and/or performing its warranties; provided that
                                                                -------- ----
any such election by the Owner will not relieve the Vendor from any obligations
or liability with respect to any such warranty.

     4.9  Payment of Subcontractors.  The Vendor must make all payments to all
          -------------------------
Subcontractors (except in the case of legitimate disputes between the Vendor and
any such Subcontractor arising out of the agreement between the Vendor and such
Subcontractor) in accordance with the respective agreements between the Vendor
and its Subcontractors such that Subcontractors will not be in a position to
enforce liens and/or other rights against the Owner, the System or any part
thereof.


     SECTION 5  TERM OF CONTRACT
<PAGE>

                                                                              50

     5.1  Initial Term.  The initial term of this Contract (the "Initial Term")

(all such periods plus the Initial Term, the "Term") following the expiration of
the Initial Term, on the same terms and conditions contained herein, unless
either Party gives notice to each other Party of its intention not to renew this
Contract within ninety (90) days prior to the expiration of the then current
Term.


     SECTION 6  PRICES AND PAYMENT

     6.1  Prices.  The prices for the Work to be performed pursuant to this
          ------
Contract (collectively, the "Contract Price") are as set forth on Schedules 2
and 3, subject to the price variation provisions contained on Schedule 2.
Notwithstanding the prices set forth on Schedules 2 and 3 and the Contract
Price, the Vendor will provide the Owner credits in aggregate value not to
exceed [   ] to purchase any Products in the following System Areas and in the
following amounts per such System Areas:


                      System       Credit
                       Area        Amount
                    -----------  ----------
                    Detroit      [   ]
                    Milwaukee    [   ]
                    Denver       [   ]
                    Salt Lake    [   ]
                    Spokane      [   ]

The Owner is also entitled to additional purchase credits of up to [   ] to be
applied in the Owner's discretion to the purchase of any Products in any or all
of the above listed System Areas. At any time during the Term of this Contract
that the Owner wishes to apply the purchase credits referenced in this
subsection 6.1 to any of its Products purchases for the System Areas listed
immediately above, the Owner must notify the Vendor of its intent to do so and
it will be the Vendor's sole responsibility, throughout the Term of this
Contract, to keep account of the remaining purchase credits available to the
Owner. Prices for the Work not otherwise set forth on Schedules 2 or 3, if not
otherwise set forth in this Contract, will be no greater than the Vendor's best
list prices then in effect at the time of ordering by the Owner (as established
by the Vendor's then applicable Customer Price Guide for sales in the United
States) and at discounts otherwise provided to the Owner pursuant to the terms
of this Contract.

     6.2  Price Reduction.  The Contract Price will be reduced by all amounts
          ---------------
saved as a result of Engineering changes suggested by the Owner which are
incorporated into the Specifications by the Vendor provided that the Vendor
                                                   --------
reasonably believes that such changes will not make it impossible or
impracticable to comply with any of its obligations under this
<PAGE>

                                                                              51

Contract, including, without limitation, those Vendor obligations relating to
the performance criteria applicable to the System.  Any reduction in Contract
Price pursuant to the preceding sentence will be agreed upon promptly by the
Owner and the Vendor.  Failure of the Parties to mutually agree to such price
reductions within ten (10) days from the date the Owner delivered written notice
to the Vendor of the need for such price reduction due to incorporated
Engineering changes will result in the automatic reference of such matter to
dispute resolution in accordance with subsection 23.1.  During the pendency of
any such dispute resolution prices payable pursuant to subsection 6.1 will be
payable by the Owner to the Vendor at the reduced level pursuant to this
subsection 6.2.  If in accordance with subsection 23.1 such dispute resolution
results in a finding that such price reduction was not in fact justified then
the Owner will reimburse the Vendor the amounts that would otherwise have been
payable to the Vendor during the pendency of such dispute resolution.

     6.3  Payments.  Except with respect to Facilities Preparation Services and
          --------

          --------------------------------------
provision to the contrary contained herein, the Owner will have no obligation to
make any payment with respect to the affected PCS System in addition to amounts
previously paid to the Vendor at any time the Vendor is in material breach of
this Contract with respect to such PCS System until and unless such breach is
cured or waived by the Owner in accordance with the terms of this Contract.

modify the Vendor's obligations as to the completion of testing in accordance
with Exhibit B3 once Microwave Relocation in such affected PCS System or
affected portion of a PCS System has been successfully achieved by the Owner.
Nothing contained herein to the contrary will in any way require the Owner to
pay the Vendor amounts already paid or otherwise provided for pursuant to any
other provision of this Contract.

     6.8  In Revenue Payments.  At any time during the Site Acquisition Delay
          -------------------
Period or the Microwave Delay Period, as the case may be, the Owner may, in its

fact decide, in its sole discretion, to place any PCS System or any portion of a
PCS System into In Revenue Service during any such Site Acquisition Delay Period
or Microwave Delay Period, as the case may be, the Owner will be obligated to
pay to the Vendor the amounts it would have otherwise paid to the Vendor upon
the Substantial Completion of such In Revenue PCS System or In Revenue portion
of such PCS System, as the case may be, and the Vendor will be entitled to
commence Substantial Completion testing for such In Revenue PCS System or In
Revenue portion of such PCS System; provided that the Owner understands that the

mutual agreement of the Parties at such time) to such In Revenue PCS System or
In Revenue portion of such PCS System.  The Parties expressly understand and
agree that this subsection 6.8 will only be effective in the event that the
Owner chooses, in its sole discretion, to place a PCS System or a portion
thereof In Revenue during a Microwave Delay Period or Site Acquisition Delay
Period, as applicable to such In Revenue PCS System or In Revenue portion of
such PCS System.  Nothing contained herein to the contrary will in any way
modify the Vendor's obligations as to the completion and testing of the
remaining incomplete non-In Revenue portion of any such PCS System which is
otherwise partially In Revenue pursuant to and in accordance with the terms of
this Contract, including but not limited to the Project Milestones set forth on
Exhibit A1.  Nothing contained herein to the contrary will in any way require
the Owner to pay the Vendor

of the PCS Systems so as to cause no unauthorized interference with or
obstruction to lands and thoroughfares or rights of way on or near which the
Installation work may be performed.  The Vendor must exercise every reasonable
safeguard to avoid damage to existing facilities, and if repairs or new
construction are required in order to replace facilities damaged by the Vendor
due to its carelessness, negligence or willful misconduct, such repairs or new
construction will be at the Vendor's sole cost and expense.


     SECTION 9  ACCEPTANCE TESTING AND ACCEPTANCE

     9.1  Acceptance Testing.  The Vendor must carry out the Acceptance Tests on
          ------------------
the Products and the PCS Systems as specified in Exhibit B3 and each PCS System
must successfully achieve acceptance (including Substantial Completion and Final
Acceptance) in accordance with the terms of Exhibit B3.

     9.2  Costs and Expenses.  The costs and expenses of such Acceptance Tests
          ------------------
will be borne by the Vendor, and the Owner will not be charged or billed for
such costs and expenses, except to the extent that such charges or expenses are
not included in the Contract Price pursuant to and in accordance with the terms
of this Contract.  If the Acceptance Tests performed by the Vendor are not
satisfied in accordance with the relevant requirements of Exhibit B3 or are
otherwise inconclusive in the reasonable judgment of the Owner, the Owner will
have the right to order further Acceptance Tests at the sole cost and expense of
the Vendor.

     9.3  Notification.  The Vendor will notify the Owner at least ten (10) days
          ------------
prior to the performance of any Acceptance Tests.  Prior to or at the first
practicable date after such notification, the Vendor and the Owner will each
agree upon and approve any test forms to be used as part of the particular
Acceptance Test being conducted.

     9.4  Presence at Acceptance Tests.  The Owner and its representatives will
          ----------------------------
be permitted to witness and have unrestricted access to the Vendor's and its
Subcontractors' Acceptance Tests, provided that no such access will materially
                                  -------- ----
interfere with or cause undue delay of the Vendor's Work.  Nothing herein will
be deemed to require the Vendor to reimburse the Owner for any costs incurred by
the Owner in the Owner's participation in or
<PAGE>

                                                                              57

observation of Acceptance Tests or other tests performed by the Vendor pursuant
to and in accordance with the terms of this Section 9.

     9.5  Correction of Defects.  (a) If any Acceptance Test is not satisfied,
          ---------------------
the Vendor will, at its sole cost and expense, (i) in writing, notify the Owner
of such failure, and (ii) promptly correct whatever Defects or Deficiencies
caused such Acceptance Test not to be satisfied.  After such correction, the
Vendor must (i) repeat at its sole cost and expense the failed Acceptance Tests
and as many other Acceptance Tests as are necessary to ensure in the reasonable
opinion of the Owner that such correction made by the Vendor would not have
affected the outcome of such other Acceptance Tests, and (ii) in writing, notify
the Owner as to what correction was made and what Acceptance Tests were
repeated.

     (b)  If Final Acceptance of a PCS System cannot be achieved after
Substantial Completion of such PCS System (provided that the Vendor will have
fully built-out the Final RF Engineering Plan in accordance with the Final Site
Count in accordance with the terms of this Contract) because such PCS System
fails to meet applicable performance criteria as set forth in Exhibit F, but
would do so with only the implementation and installation of additional Base
Stations at additional System Element Locations over and above the Final Site
Count for such PCS System, the Owner will have the right, in its sole and
absolute discretion, to (i) Finally Accept such PCS System in which case the
Parties will mutually agree in good faith on revised performance criteria for
such PCS System, or (ii) require the Vendor to continue to work (in which case
Final Acceptance of such PCS System will be delayed until completion of the work
and testing contemplated herein and in Exhibit B3) to cause such PCS System to
perform at the applicable levels of the then existing performance criteria as
set forth in Exhibit F, in which case, the required additional Base Stations and
additional System Element Locations will be treated as provided for in
subsections 17.5(c) and 17.10.  Any additional Base Station(s) paid for by the
Owner pursuant to this subsection 9.5(b) (which would only have to be paid for
(including any costs associated with the installation thereof) by the Owner upon
the subsequent achievement of Final Acceptance by the Vendor in accordance with
Exhibit B3 which such payment will be made with the payments otherwise made on
Final Acceptance pursuant to Section 6) will be offset against the number of
new Base Stations that may subsequently be for the account of the Owner pursuant
to the terms of subsection 17.5(c).  If the Parties are unable to agree upon
revised performance criteria as provided in clause (i) above, the matter will be
resolved in accordance with the provisions of subsection 23.3.

     9.6  Acceptance Certificate.  Upon the successful completion of the
          ----------------------
Acceptance Tests for a PCS System or any part thereof conducted by the Vendor,
the Vendor must submit to the Owner an Acceptance Certificate certifying that
(i) such Acceptance Tests have been successfully completed, (ii) the Work so
tested has been completed in accordance with the terms of this Contract, and
(iii) if applicable, that the remainder of the Work is continuing in accordance
with the Project Milestones set forth on Exhibit A.  Upon its reasonable
satisfaction that such Acceptance Certificate is correct and complete, the Owner
will acknowledge such certification by signing the Acceptance Certificate.  In
the event of any dispute as to the results of any Acceptance Tests, such dispute
will be resolved pursuant to
<PAGE>

                                                                              58

the dispute resolution mechanisms set forth in Section 23 including, but not
limited to, the Third Party Engineer review mechanism set forth in subsection
23.3.


     SECTION 10  DISCONTINUED PRODUCTS

     10.1  Notice of Discontinuation.  During the Term of this Contract the
           -------------------------
Vendor agrees to provide the Owner, or the respective Affiliates as the case may
be, except under extraordinary circumstances not less than one (1) year notice
before the Vendor discontinues accepting orders for a PCS Product ("Discontinued
Products") sold under this Contract.  Where the Vendor offers a product for sale
that is equivalent in form, fit and function in accordance with and pursuant to
the Specifications, the notification period may vary but in no event will be
less than the applicable notice period set forth in subsection 2.17.
Notwithstanding the foregoing, the Vendor will not discontinue accepting orders
for any PCS Product applicable to or otherwise used in the System or any portion
thereof until and unless the Vendor and the Owner have agreed upon a mutually
acceptable transition plan that takes into account the Owner's and its
Affiliates' existing investment in the Item scheduled for discontinuance subject
to the minimum terms and conditions set forth in subsections 10.2 and 10.3
below.  The Parties' failure to reach agreement within sixty (60) days or such
other reasonable time as they may mutually establish will, upon the request of
either Party, be referred for resolution pursuant to Section 23.  In the event
of the foregoing, the Vendor must continue to furnish PCS Products fully
compatible with the System Elements within the System at such time during the
Term of the Contract; provided that nothing herein will bar the Vendor from
                      -------- ----
discontinuing individual Items of PCS Products as provided in and pursuant to
this subsection 10.1.

     10.2  Discontinuation During Warranty Period.  If, during the Warranty
           --------------------------------------
Period applicable to the relevant Discontinued Product pursuant to Section 17,
the Vendor does not make such Discontinued Products available to the Owner, the
price of any Products provided as a replacement for the Discontinued Product by
the Vendor and required to be purchased by the Owner during such Warranty Period
to replace existing Discontinued Products delivered to the Owner in order to
maintain performance and functionality equivalent to that previously provided by
the Discontinued Products will be discounted by an amount equal to fifty percent
(50%) of the price previously paid for such Discontinued Products.

     10.3  Discontinuation After Warranty Period.  In the event that the Vendor
           -------------------------------------
discontinues the manufacture of a Product following the expiration of the
applicable Warranty Period and the Owner is required to replace an existing
Discontinued Product with a new Product in order to maintain performance and
functionality, the Owner will receive a credit in an amount equal to the
percentage set forth below multiplied by the purchase price paid for such
original Product, which credit will be applied against the Vendor's then-current
list price for a replacement for such Discontinued Product; provided that the
                                                            -------- ----
credit will not exceed the Vendor's then-current best list price (as determined
by the Customer Price Guide) for such replacement Product subject to the
discounts available to the Owner pursuant to Section 26 and the other terms of
this Contract:
<PAGE>

                                                                              59

                (i)   up to and including one year following expiration
                      of the applicable Warranty Period:  40%;

               (ii)   more than one year and up to and including two years
                      following expiration of the applicable Warranty Period:
                      30%; and

               (iii)  more than two years and up to and including three years
                      following expiration of the applicable Warranty Period:
                      20%.


     SECTION 11  SOFTWARE; CONFIDENTIAL INFORMATION

     11.1  RTU License.  The Owner is hereby granted a perpetual, non-exclusive,
           -----------
non-transferable (except as set forth in subsections 11.4 and 27.4), fully paid-
up, multi-site (capability to move Software from site to site) right to use
license for the Software ("RTU License"), to operate the Products provided in
each of the PCS Systems and the System as a whole, subject to payment of any
license fees in accordance with the terms of this Contract.  Except as otherwise
provided herein, the Owner is granted no title or ownership rights to the
Software.  Such rights will remain with the Vendor, its Subcontractors or
suppliers, as appropriate.

     11.2  Owner's Obligations.  The Owner agrees that the Software, whether or
           -------------------
not modified, will be treated as proprietary to the Vendor, its Subcontractors
or its suppliers, as appropriate and the Owner will:

     (a)  Utilize the Software solely in conjunction with the System and/or any
PCS System; provided that the Vendor acknowledges that the Software will be
            -------- ----
integrated across interfaces with systems, equipment and software provided by
other suppliers and customers including, but not limited to, the Other Vendors;

     (b)  Ensure that all copies of the Software will, upon any reproduction by
the Owner authorized by the Vendor and whether or not in the same form or format
as such Software, contain the same proprietary, confidentiality and copyright
notices or legends which appear on the Software provided pursuant hereto; and

     (c)  Hold secret and not disclose the Software (or, subject to subsection
27.19, interfaces to or with such Software) to any person, except to (i) such of
its employees, contractors, agents or Affiliates that are involved in the
operation or management of the System and/or any PCS System and need to have
access thereto to fulfill their duties in such capacity, or (ii) other Persons
who need to use such Software to permit integration of the System and/or any PCS
System with systems and software of other suppliers and customers including, but
not limited to, the Other Vendors; provided that such persons agree, or are
                                   -------- ----
otherwise obligated, to hold secret and not disclose the Software to the same
extent as if they were subject to this Contract.

reasonable written disposition instructions provided by the Vendor.  If the
Vendor authorizes disposition by erasure or destruction, the Owner will remove
from the medium on which Software resides all electronic evidence of the
Software, both original and derived, in such manner that prevents subsequent
recovery of such original or derived Software.

     11.3  Backwards Compatibility.  (a)  In addition to the warranties
           -----------------------
contained in Section 17 of this Contract, the Vendor represents and warrants
that each Software Revision Level during the Term of this Contract will be
Backwards Compatible with all existing in-service Equipment provided by the
Vendor and the immediately preceding Software Revision Level of such Software
made available to Customers by the Vendor.

     (b)  In the event that Software supplied by the Vendor at any System
Element Site at any time does not provide Backwards Compatibility as required by
this subsection 11.3, then the Vendor will provide, without charge to the Owner,
the most current Software Updates of the Software to each such System Element
Location, and otherwise take such steps as may be necessary to achieve Backwards
Compatibility.

     11.4  Transfer and Relocation.  (a)  Except as provided in subsection 27.4,
           -----------------------
where the Owner or any successor to the Owner's title in the Products (i) elects
to transfer a Product to a third party, and where such Product will remain in
place and operational for the purpose of continuing to provide PCS in the
franchise area in which such Product is installed, or (ii) elects to transfer
Products to an Affiliate for reuse within the United States, the Owner may
transfer its RTU License for the Software furnished under this Contract for use
with such Product, without the payment of any additional Software right-to-use
fees by the transferee, but only under the following conditions:

          (A)  The right to use such Software may be transferred only together
               with the Products with which the Owner has a right to use such
               Software, and such right to use the Software will continue to be
               limited to use with such Products;

          (B)  Before any such Software are transferred, the Owner will notify
               the Vendor of such transfer and the transferee will have agreed
               in writing (a copy of which will be provided to the Vendor) to
               keep the Software in confidence and to corresponding conditions
               respecting possession and use of Software as those imposed on the
               Owner in this Contract; and

     (b) Except as provided in subsection 11.4(a) or subsection 27.4, and except
as may otherwise in this Contract be provided expressly, the Owner or any
successor to the Owner's title in the Products will have no right to transfer
Software furnished by the Vendor under this Contract without the consent of the
Vendor.  If the Owner or such successor elects to transfer a Product purchased
under this Contract for which it does not under this Contract have the right to
transfer related Software, the Vendor agrees that upon written request of the
transferee of such Product, or of the Owner or such successor, the Vendor will
not without reasonable cause fail to grant to the transferee a license to use
such Software with the Products, whether to be located within the United States
or elsewhere, upon payment of a relicensing fee to the Vendor in an amount equal
to fifty percent (50%) of the license fee for the Software originally paid by
the Owner to the Vendor at the time of the original purchase of the Software
from the Vendor; provided that such relicensing fee will in no event exceed
                 -------- ----
fifteen percent (15%) of the price paid by the transferee to the Owner for the
Product with respect to which such Software is used.

     11.5  Survival.  The obligations of the Owner under the Software Licenses
           --------
will survive the termination of this Contract, regardless of the cause of
termination.

     11.6  Access to Source Codes.  The Vendor grants the Owner a right to
           ----------------------
access the Source Code and to modify the Software (the "RTM License") for the
maintenance, enhancement and support of those Products purchased from the Vendor
and owned or operated by the Owner under the following circumstances which will
be set forth in the Escrow Agreement:

     (a)  If the Vendor becomes insolvent, makes a general assignment for the
benefit of creditors, files a voluntary petition in bankruptcy or an involuntary
petition in bankruptcy is filed against the Vendor which is not dismissed within
sixty (60) days, or suffers or permits the appointment of a receiver for its
business, or its assets become subject to any proceeding under a bankruptcy or
insolvency law, domestic or foreign, or has liquidated its business, or the
Vendor, or a business unit of the Vendor that is responsible for maintenance of
the Software, ceases doing business without providing for a successor, and the
Owner has reasonable cause to believe that any such event will cause the Vendor
to be unable to meet its warranty service or support requirements hereunder; or

     (b)  If it is determined, pursuant to the dispute resolution mechanisms set
forth in subsection 23.1, that the Vendor, its assignee or designee has failed,
or is unable, to provide the warranty service or support of the System and/or
any PCS System contemplated by this Contract.

     11.7  Escrow Agreement.  The Vendor agrees, at the Owner's request, to
           ----------------
become party to a Source Code escrow agreement (the "Escrow Agreement") which
will allow the Owner to obtain access to the applicable Source Codes in the
circumstances set forth in subsection 11.6 and such Escrow Agreement.  The Owner
will pay all costs, including the Vendor's reasonable costs incurred in
gathering, organizing and delivering such Source Code, associated with such
Escrow Agreement.  The Vendor represents, warrants and agrees that (i) the
Source Codes delivered into escrow in accordance with the Escrow Agreement will

                                                                              62

comprise the full Source Code language statement of the Software as used, or
required to be used, by the Vendor to maintain or modify the System and/or any
PCS System without the help of any other Person or reference to any other
material, (ii) such Source Codes will include all versions thereof from the date
of initial creation, and (iii) such Source Codes must be kept up to date,
including all updates needed to maintain compliance with the Specifications and
the System Standards.  In addition, all parts of the Source Codes from the date
of creation thereof, and all updates thereto (including, without limitation,
those that are necessary to maintain compliance with the Specifications) must be
delivered into escrow in accordance with the Escrow Agreement.

     11.8  Software Maintenance.  The Vendor represents and warrants that the
           --------------------
Software delivered to the escrow agent pursuant to subsection 11.7 for
redelivery to the Owner pursuant to the Escrow Agreement will be in a form
suitable for reproduction by the Owner and will include the full Source Code
language statement of the Software as used by the Vendor sufficient to allow
maintenance and modification.

     11.9  Custom Development.  11.9.1  Request for Custom Material.  (a)  From
           ------------------           ---------------------------

Software or Software Enhancements) or custom development of Equipment
(including, but not limited to, development of identified features or
modifications to Equipment or Equipment Enhancements) to be provided by the
Vendor under this Contract (the "Custom Material").  If the Owner has a
requirement for Custom Material that is a specific enhancement or modification
of a previously licensed feature or of previously purchased Products, the Owner
will identify to the Vendor in writing a summary of any such proposed
development of Custom Material.  Such summary will provide a description of any
proposed Custom Material sufficient to enable the Vendor to determine the
general demand for, and its plans, if any, to develop the same or similar
Products.  The Vendor will respond to such summary within thirty (30) days after
receipt thereof and indicate if it has the ability to fulfill a subsequent
Request for Proposal ("RFP") from the Owner for such development of Custom
Material.  The Owner acknowledges that the Vendor will have no obligation to
develop any proprietary materials for Owner.

     (b)  If the Vendor decides that it does not have the technical ability or
the capacity to fulfill a subsequent RFP for such Custom Material development,
the Vendor's response pursuant to subsection 11.9.1(a) will (i) provide the
Owner an explanation of why it cannot fulfill such RFP and (ii) use reasonable
diligence to work with the Owner to identify an alternative source for such
development reasonably acceptable to the Owner.  In determining whether the
Vendor has the technical ability or the capacity to fulfill the RFP, the Vendor
may consider factors including, but not limited to, (1) the Vendor's likelihood
of recovering its costs for performing such development, (2) the impact of such
development on the Vendor's actual outstanding commitments to perform work for
other Customers and to pursue strategic development activities; and (3) whether
the Vendor can perform the work utilizing existing software development staff
without stopping work underway.

     (c)  If the Vendor fails to agree to a request for Custom Material
development pursuant to the terms of this subsection 11.9 then the matter may,
at the Owner's option, be referred to dispute resolution pursuant to Section
23.

          11.9.2  Vendor Response.  After reviewing an RFP issued for such
                  ---------------
Custom Material, the Vendor will respond to the Owner within thirty (30) days,
unless otherwise agreed by the Parties, stating the terms and conditions upon
which the Vendor would be willing to undertake such development, including, but
not limited to, a listing of specifications, custom development charges, planned
license fees and a proposed delivery schedule.

          11.9.3  Ownership of Intellectual Property.  The Vendor will own all
                  ----------------------------------
forms of intellectual property rights (including, but not limited to, patent,
trade secret, copyright and mask rights) pertaining to Products, and will have
the right to file for or otherwise secure and protect such rights.  The
foregoing notwithstanding, the Parties understand and agree that from time to
time the Owner may devise, develop or otherwise create ideas or other concepts
for services or new products which are patentable or otherwise capable of
receiving protection from duplication.  In such event, the Owner will have the
right to patent or otherwise protect such ideas or concepts for its own use and
benefit.

     SECTION 12  SOFTWARE CHANGES

     12.1  Annual Release Maintenance Fees.  So long as the Owner pays the
           -------------------------------
applicable Annual Release Maintenance Fees in accordance with the terms of this
Contract during the Term (including at any time after the Term so long as the
Owner at such time continues to pay the Annual Release Maintenance Fees), the
Vendor will provide to the Owner, at such times as they become generally
available to the Vendor's Customers, all Software Upgrades, all Software
Enhancements and all Combined Releases (but not Optional Software Features,
unless otherwise mutually agreed between the Parties) applicable to Software for
PCS Products for which the Owner has obtained a RTU License pursuant to the

     12.4  Software Fixes.  In the event that any Software Upgrade, Software
           --------------
Enhancement or Software Combined Release supplied by the Vendor during the Term
of this Contract has the effect of preventing the System and/or any PCS System
or any part thereof from satisfying, or performing in accordance with the
Specifications, the System Standards and/or Exhibit F or otherwise adversely
affects the functionality or features of the System, any PCS System or any part
thereof, then the Vendor will promptly retrofit or take such other corrective
action as may be necessary to assure that the System, any such PCS System or any
such affected part, as modified to include each such Software Upgrade, Software
Enhancement or Software Combined Release, will satisfy, and perform in
accordance with, the Specifications, the System Standards and/or Exhibit F and
restore all pre-existing functionality and features as well as provide any new
features and functionality provided by any of the foregoing modifications, in
each case without any charge to the Owner (other than payment of the applicable
Annual Release Maintenance Fees pursuant to the terms of this Contract).

Owner by the Vendor at no charge to the Owner as provided in subsection 13.1(b)
below.  Equipment Enhancements must be provided to the Owner by the Vendor, if
requested by the Owner, and the Owner is obligated to make payment therefor in
an amount that is no higher than that payable by any Customer other than the
Owner, which amount of payment will be adjusted as set forth in subsections 6.2,
7.2 and 27.16 and Section 26.  If the Vendor at any time issues an Equipment
Upgrade which is combined with any Equipment Enhancement (collectively, the
"Equipment Combined Release") to such Equipment, the Equipment Combined Release
will be provided at no charge to the Owner unless and until the Owner elects to
use any of the feature enhancement or enhancements included within the Equipment
Combined Release and has accepted such Equipment Combined Release.

     (b) (i) After a PCS Product has been shipped to the Owner, if the Vendor
issues an Equipment Upgrade ("Class A change") or Equipment Enhancement ("Class
B change"), or where a modification to correct an error in field documentation
is to be introduced, the Vendor will promptly notify the Owner of such change
through the Vendor's design change management system or another Vendor
notification procedure.  Each change notification, whether or not it bears a
restrictive legend, will be subject to subsection 27.19, except that such
information may be reproduced by the Owner for the Owner's use as required
within the System.  If the Vendor has engineered, furnished, and installed a
Product which is subject to an Equipment Upgrade, the Vendor will implement such
change, at its sole cost and expense, if it is announced within fifteen (15)
years from the date of shipment of that Product, by, at its option (subject to
the reasonable review and acceptance of the Owner at such times as the Owner
reasonably determines that it needs to review such Vendor decision), either (A)
modifying the Product at the Owner's site; (B) modifying the Product which the
Owner has returned to the Vendor in accordance with the Vendor's reasonable
instructions pursuant to and in accordance with the terms of this Contract; or
(C) replacing the Product requiring the change with a replacement Product for
which such change has already been implemented.  If
<PAGE>

                                                                              65

the Vendor has not engineered the original Product application and accordingly
office records are not available to the Vendor, the Vendor will provide the
generic change information and associated parts for the Owner's use in
implementing such change.

          (ii) In any of the instances described in clause (i) above, if the
               Vendor and the Owner agree that a Product or part thereof subject
               to such change is readily returnable, the Owner, at its expense,
               will remove and return such Product or part to the Vendor's
               designated facility within the United States and the Vendor, at
               its sole expense, will implement such change (or replace it with
               a Product or part for which such change has already been
               implemented) at its facility and return such changed (or
               replacement) Product or part at its sole cost and expense to the
               Owner's designated location within the United States. Any such
               reinstallation will be performed by the Owner at its sole
               expense. At any such time that the Owner's spares or plug-in
               stocks are not available to implement a rotational program for an
               Equipment Upgrade, the Vendor will provide a seed stock, where
               feasible and necessary.

          (iii)If the Owner does not make or permit the Vendor to make an
               Equipment Upgrade as stated above within one (1) year from the
               date of change notification or such other period as the Vendor
               may agree, subsequent changes, repairs or replacements affected
               by the failure to make such change may, at the Vendor's option,
               be invoiced to the Owner whether or not such subsequent change,
               repair or replacement is covered under the warranty provided in
               this Contract for such Product. If requested by the Owner,
               Equipment Upgrades announced more than fifteen (15) years from
               the date of shipment will be implemented at the Owner's expense.

          (iv) If the Vendor issues an Equipment Enhancement after a PCS Product
               has been shipped to the Owner, the Vendor will promptly notify
               the Owner of such change if it is being offered to any of the
               Vendor's Customers.  Except as otherwise set forth above in
               subsection 13.1(a), when an Equipment Enhancement is requested by
               the Owner, the pricing set for such Equipment Enhancements will
               be at the Vendor's standard charges subject to the applicable
               discounts set forth in this Contract and Section 26.

          (v)  All change notifications for Equipment Upgrades and Equipment
               Enhancements provided by the Vendor to the Owner pursuant to the
               terms of this Contract must contain the following information:
               (i) a detailed description of the change; (ii) the reason for the
               change; (iii) the effective date of the change; and (iv) the
               implementation schedule for such change, if appropriate.

     13.2  Notice.  The Vendor will give the Owner not less than ninety (90)
           ------
days, prior written notice of the introduction of any Equipment Enhancement or
any Equipment Combined Release.  In addition, in each February and August of
each year during the Term of this Contract, the Vendor will provide the Owner
with a forecast of future Equipment Enhancements to the Equipment or Equipment
Combined Releases then currently being developed by or on behalf of the Vendor.


     13.3  Installation, Testing and Acceptance.  The Installation and testing
           ------------------------------------
of the Equipment by the Vendor and the acceptance thereof by the Owner must be
performed in accordance with Exhibit B3 pursuant to the Project Milestones in
Exhibit A.

     13.4  Equipment Fixes.  In the event that any Equipment Upgrade or
           ---------------
Equipment Enhancement supplied by the Vendor during the Term of this Contract
has the effect of preventing the System and/or any PCS System or any part
thereof from satisfying, or performing in accordance with, the Specifications,
the System Standards and/or Exhibit F or otherwise adversely affects the
functionality, interoperability or features of the System, any such PCS System
or any part thereof then the Vendor will without any charge to the Owner
promptly retrofit or take such other corrective action as may be necessary to
assure that the System, any such PCS System or any such affected part, as
modified to include each such Equipment Upgrade and Equipment Enhancement, will
satisfy, and perform in accordance with, the Specifications, the System
Standards and/or Exhibit F and restore all pre-existing functionality and
features as well as provide any features and functionality provided by any of
the foregoing modifications.


     SECTION 14 INTELLECTUAL PROPERTY

     14.1  Intellectual Property.  The Vendor grants the Owner rights to state
           ---------------------
that it is using the Vendor's Products or Services in the Owner's marketing,
advertising or promotion of the System, any PCS System or any part thereof.  The
Owner has the right to use for such marketing, advertising or promotion the
Vendor's advertising and marketing materials (including pamphlets and brochures)
provided to the Owner by the Vendor describing the System, any PCS System or any
part thereof, or any Product.  Other than as set forth in this subsection 14.1,
the Owner has the right to use the trademarks and service marks of the Vendor or
its assignee in the Owner's marketing, advertising and promotion of the System,
any PCS System or any part thereof only with the written consent of the Vendor
not to be unreasonably withheld subject to and in accordance with the terms of
subsection 27.13.

     14.2  Infringement.  (a) The Vendor agrees that it will defend, at its own
           ------------
expense, all suits and claims against the Owner for infringement or violation
(whether by use, sale or otherwise) in the United States of any patent,
trademark, copyright, trade secret or other intellectual property rights of any
third party (collectively, "Intellectual Property Rights"), covering, or alleged
to cover, the Equipment, Software, the System and/or any PCS System or any
component thereof for its intended use, in the form furnished or as subsequently
modified by the Vendor or as otherwise modified by the Owner pursuant to the
direction or approval of
<PAGE>

                                                                              67

the Vendor.  The Vendor agrees that it will pay all sums, including, without
limitation, attorneys' fees and other costs, which, by final judgment or decree,
or in settlement of any suit or claim to which the Vendor agrees, may be
assessed against the Owner on account of such infringement or violation,

provided that:
- - - -------- ----

          (i)  the Vendor will be given prompt written notice of all claims of
               any such infringement or violation and of any suits or claims
               brought or threatened against the Owner or the Vendor of which
               the Owner has actual knowledge;

          (ii) the Vendor will be given full authority to assume control of the
               defense (including appeals) thereof through its own counsel at
               its sole expense and will have the sole right to settle any suits
               or claims without the consent of the Owner; provided that the
                                                           -------- ----
               Vendor will have no right to agree to injunctive relief against
               the Owner; provided further that the Vendor will notify the
                          -------- -------
               Owner of any proposed settlement condition prior to the
               Vendor's acceptance of such settlement; and

          (iii)the Owner will cooperate fully with the Vendor in the defense of
               such suit or claims and provide the Vendor, at the Vendor's
               expense, such assistance as the Vendor may reasonably require in
               connection therewith.

     (b)  The Vendor's obligation under this subsection 14.2 will not extend to
alleged infringements or violations that arise because the Products provided by
the Vendor are used in combination with other products furnished by third
parties and where any such combination was not installed, recommended, approved,
explicitly or by implication, by the Vendor.

     14.3  Vendor's Obligation to Cure.  If in any such suit so defended, all or
           ---------------------------
any part of the Equipment, Software, the System, any PCS System or any component
thereof is held to constitute an infringement or violation of Intellectual
Property Rights and its use is enjoined, or if in respect of any claim of
infringement or violation the Vendor deems it advisable to do so, the Vendor
will at its sole cost, expense and option take one or more of the following
actions:  (i) procure the right to continue the use of the same without
interruption for the Owner; (ii) subject to the terms of subsection 2.17 replace
the same with noninfringing Equipment or Software that meets the Specifications;
or (iii) modify said Equipment, Software, the System, any PCS System or any
component thereof so as to be noninfringing, provided that the Equipment,
                                             -------- ----
Software, the System, any PCS System or any component thereof as modified meets
all of the Specifications.  In the event that the Vendor is not able to cure the
infringement pursuant to clause (i), (ii) or (iii) in the immediately preceding
sentence, the Vendor will refund to the Owner the full purchase price paid by
the Owner for such infringing Product or feature, and the Owner will be under no
obligation to return to the Vendor such infringing Product or feature regardless
of whether, or by what means, the Owner, on its own or otherwise, subsequently
cures such infringement.

                                                                              68

     14.4  Vendor's Obligations.  The Vendor's obligations under this Section
           --------------------
14 will not apply to any infringement or violation of Intellectual Property
Rights caused by modification of the Equipment, Software, the System, any PCS
System or any component thereof by the Owner, or any infringement caused solely
by the Owner's use and maintenance of the Products other than in accordance with
the Specifications and the purposes contemplated by this Contract, except as
expressly authorized or permitted by the Vendor.  The Owner will indemnify the
Vendor against all liabilities and costs, including reasonable attorneys' fees,
for defense and settlement of any and all claims against the Vendor for
infringements or violations based upon this subsection 14.4.

     14.5  License to Use Vendor Patents.  (a) The Vendor grants to the Owner
           -----------------------------
and its Affiliates, under patents which the Vendor (or in the event of an AT&T
Assignment pursuant to and in accordance with subsection 27.22 the Vendor's
Successor) owns or has a right to license ("Vendor Patents"), a worldwide,
royalty-free, nonexclusive license (the "Patent License") to use any Product
furnished by the Vendor under this Contract (including any combination of
products and services, whether or not furnished at the same time or as part of a
larger combination) for provision of telecommunications services; provided,
                                                                  --------
however, that no rights are conveyed to the Owner and its Affiliates with
- - - -------
respect to any invention which is directed to (i) a combination of a Product or
Products furnished with any other Item which the Vendor does not furnish to the
Owner under this Contract wholly or in part for such use, or (ii) a method or
process which is other than an inherent use of the Products furnished.  As used
in this subsection 14.5, the term "inherent use" means a use that can be
completely performed by a Product furnished by the Vendor (or a combination of
Products furnished by the Vendor), without the need for any additional product,
service, development modification or programming by the Owner and its Affiliates
or by a third party.  The Owner understands that in the event of an AT&T
Assignment pursuant to and in accordance with subsection 27.22 the Owner's
rights to any Patent Licenses granted pursuant to this subsection 14.5 will be
from the Vendor's Successor under only the patents the Vendor's Successor owns
or has a right to license and not those patents as to which there is no such
right to license.

     (b)  The Owner and any successor to the Owner's title in the Products has
the right (subject to written approval of the Vendor, which approval will not be
unreasonably withheld), to assign the Patent Licenses to any other Person who
acquires legal title to the Products including, but not limited to, any Person
or Persons who taking part in the financing or any part of the Nationwide
Network, provided that no such assignment to Persons taking part in the
         -------- ----
financing of any part of the Nationwide Network will be permitted except in
accordance with the provisions of subsection 27.4 of this Contract.  Nothing
contained in this subsection 14.5 is intended to, and shall not, limit any
rights or privileges that the Owner has under this Contract or otherwise under
Applicable Law.

     SECTION 15  DELAY

     15.1  Liquidated Damages.   The Parties agree that damages for delay are
           ------------------
difficult to calculate accurately and, therefore, agree that liquidated damages
(the "Liquidated Damages") will be paid for non-performance or late performance
of the Vendor's obligations under this Contract pursuant to the terms hereof.

     15.2  Interim Delay.  (a)  Failure of the Vendor to complete the Work
           -------------
necessary to achieve each of the Project Milestones applicable to any PCS System
(other than Milestone 3 (as set forth on Exhibit A1)) on or before the date
applicable to such Milestone for such PCS System that is required to be achieved
by the Vendor prior to the Guaranteed Substantial Completion Date for such PCS
System (each an "Interim Milestone") will result in the Vendor being liable to
pay to the Owner an amount equal to [   ]; provided that no such Interim Delay
                                           -------- ----
Penalty will be due if the delay is directly and expressly attributable solely
to (i) an event constituting a Force Majeure pursuant to the terms of this
Contract or (ii) an act or omission of the Owner. Interim Delay Penalties
accrued pursuant to this subsection 15.2(a) will be offset against the payment
to be made by the Owner to the Vendor upon Substantial Completion of the PCS
System to which such interim delay relates. The Interim Delay Penalty applicable
to Milestone 4 (as set forth on Exhibit A1) will be [   ]. This subsection 15.2
will not be applicable to Milestone 3 (as set forth on Exhibit A1) for either
the System or any PCS System.

     (b) To the extent that the Vendor is responsible for Interim Delay
Penalties pursuant to subsection 15.2(a) such penalties will be credited back to
the Vendor by the Owner to the extent that (i) the Vendor successfully achieves
the Interim Milestone subject to delay within thirty (30) days of the date
scheduled therefore pursuant to the terms hereof and Exhibit A and (ii) such
interim delay does not otherwise materially adversely affect the Owner, such PCS
System and/or the System as a whole. Any such reimbursement will be credited
back to the Vendor such that the Interim Delay Penalty otherwise offset against
the relevant Substantial Completion payment in accordance with subsection
15.2(a) above will be added back to such Substantial Completion payment to be
made to the Vendor by the Owner.

     15.3  Completion Delay.  (a)  [   ]
           ----------------

<PAGE>

                                                                              70
[   ]

     (b)  If any PCS System does not achieve Substantial Completion by the
Guaranteed Substantial Completion Date but the Owner nonetheless chooses (in its
sole discretion) to commence In Revenue Service in such incomplete PCS System
(such action in no way constituting the Owner's acceptance, express or implied,
of the System or such PCS System or any part thereof), then the Vendor will be
required to pay, on a daily basis, only that percentage of the daily Late
Completion Payment equal to that percentage of the geographic area to be
otherwise covered by such PCS System not otherwise placed In Revenue Service by
the Owner.

     (c)  In the event of a change in the Product Contract Price pursuant to
subsections 6.2, 7.2 or 27.16 or Section 26 during the Term of this Contract
from the amount originally set forth in this Contract pursuant to Section 6 the
per diem amount of Late Completion Payments set forth above will be increased or
decreased, as appropriate, by an amount equal to the increase or decrease in the
Owner's per diem interest payment obligation resulting from any change in the
amount of debt incurred or to be incurred by the Owner related to such change in
the Product Contract Price.

     (d)  Late Completion Payments, including any portions of such payments
payable in accordance with paragraphs (a) and (b) above, will be accrued during
the Completion Cure Period and offset against payments otherwise due to the
Vendor upon the achievement of Substantial Completion pursuant to the terms of
subsection 6.3.  If the Vendor fails to achieve Substantial Completion within
sixty (60) days of the Guaranteed Substantial Completion Date for any reason
other than primarily because of (i) a Force Majeure event pursuant to Section
16 or (ii) the direct and explicit act or omission of the Owner, then the Owner
will have the option to terminate this Contract with respect to the PCS System
affected by any such delay without any penalty or payment obligation (other than
payment obligations under this Contract outstanding as of the date of any such
termination; provided that any such amounts payable by the Owner will not
             -------- ----
include any amounts that would have been payable to the Vendor only upon
Substantial Completion or Final Acceptance); provided further that in the event
                                             -------- -------
the Vendor fails to achieve Substantial Completion within such sixty (60) day
period in any two (2) PCS Systems within the Initial System over any period of
time (regardless of whether such events are concurrent or whether the first such
event was subsequently cured) the Owner will have the right, but not the
obligation, to terminate this Contract in its entirety.


     SECTION 16  FORCE MAJEURE

     16.1  (a)  Either Party may make a claim for excusable failure or delay
with respect to any obligation of such Party under this Contract, except any
obligation to make payments when due.  Excusable failure or delay will be
allowed only in the event of an event of Force Majeure that is beyond the
reasonable control of the affected Person.  Notwithstanding the foregoing, the
Vendor will not be entitled to relief under this Section 16 to the extent that
any event otherwise constituting an event of Force Majeure results from the
negligence or fault of
<PAGE>

                                                                              71

the Vendor or any Subcontractor, and the Owner will not be entitled to relief
under this Section 16 to the extent any event otherwise constituting an event
of Force Majeure results from the negligence or fault of the Owner.

     (b)  The Party claiming the benefit of excusable delay hereunder must (i)
promptly notify the other Party of the circumstances creating the failure or
delay and provide a statement of the impact of such Party failure or delay and
(ii) use reasonable efforts to avoid or remove such causes of nonperformance,
excusable failure or delay.  If an event of Force Majeure prevents the Vendor
from performing its obligations under this Contract for a period exceeding sixty
(60) days, the Owner may, upon prior written notice to the Vendor, terminate
this Contract.

     (c)  The Party not claiming the benefit of excusable delay hereunder will
likewise be excused from performance of its obligations hereunder on a day-for-
day basis to the extent such Party's obligations are affected due to the other
Party's delayed performance.

     (d)  In the event of a Force Majeure which the Party claiming relief for
such event has used all best efforts to resolve in accordance with the terms of
this Contract, upon the written request of either Party, the other Party will in
good faith negotiate modifications, to the extent reasonable and necessary, in
scheduling and performance criteria in order to reasonably address the impact of
such Force Majeure.

     SECTION 17  WARRANTIES

     17.1  Product Warranty.  (a) The Vendor warrants that, for a period of two
           ----------------
(2) years from the date of Final Acceptance of any PCS System (the "Product
Warranty Period"), all Products and all of the Installation and the
Configuration Engineering thereof within such PCS System will materially conform
with and perform the functions set forth in the Specifications and the relevant
performance criteria set forth in Exhibit D, to the extent applicable, and will
be free from Defects and Deficiencies in material or workmanship which impair
service to subscribers, System performance, billing, administration and/or
maintenance.  In the case of Software, the Product Warranty Period applicable to
any such Software will be automatically extended upon, and simultaneous with,
any Software Upgrade issued pursuant to the terms of Section 12.  The Vendor
will assign to the Owner all outstanding Subcontractor warranties attributable
to Non-Essential Equipment at such time that the Vendor's warranty on such Non-
Essential Equipment pursuant to this subsection 17.1 expires pursuant to and in
accordance with the Product Warranty Period applicable to such Item of Non-
Essential Equipment.  The Warranty Period for a PCS Product or part thereof
repaired or provided as a replacement under this Product warranty is six (6)
months or the unexpired term of the new Product Warranty Period applicable to
the repaired or replaced PCS Product or part, whichever is longer.

     (b) To the extent the Owner orders additional Products from the Vendor in
accordance with the terms of this Contract including, but not limited to,
subsections 2.2 and/or 7.2, any such Products so ordered by the Owner and
delivered and installed by the Vendor or its Subcontractors will be warranted to
the same extent as set forth in clause (a) above for a
<PAGE>

                                                                              72

period of not less than twenty four (24) months from the earlier of (i) the date
the Owner puts such additional Products into In Revenue Service, (ii) the date
of the Owner's acceptance and (iii) thirty (30) days after the Vendor completes
the installation of such additional Products.  If in the event, pursuant to the
Owner's order for such additional Products the Vendor is not required to install
such additional Products, the warranty on such additional products will run
twenty-four (24) months from the date the Vendor shipped such products to the
Owner.

     17.2  Services Warranty.  (a) The Vendor warrants that, for a period of not
           -----------------
less than three (3) years from the date of completion of RF Engineering done by
the Vendor or its Subcontractors (but in no event earlier than the achievement
of Milestone 5 in such PCS System) in any given PCS System (the "RF Services
Warranty Period") the Final Site Count within and the Final RF Design applicable
to such PCS System will be accurate based upon the environmental circumstances
in such PCS System as they existed at the time of the Final Acceptance of such
PCS System provided that the projections of subscriber growth, traffic and other
           -------- ----
predictive data, including all applicable standards as identified in Exhibits
B1, D and H, upon which the Final Site Count and Final RF Design have been
determined, have not been materially exceeded or the applicable and relevant
industry standards have not materially changed; and provided further that in no
                                                    -------- ------- ----
event will the RF Engineering warranty pursuant to this subsection 17.2(a) cover
or warrant items or performance otherwise covered or warranted pursuant to
subsection 17.3 below.

     (b)  The Vendor warrants that, for a period of not less than two (2) years
from the date of completion of Facilities Preparation Services within any PCS
System but in no event later than the achievement of Milestone 8 pursuant to
Exhibit A1 in such PCS System (provided that in the event of a Microwave Delay
                               -------- ----
Period in such PCS System pursuant to subsection 23.8, the commencement of the
Facilities Preparation Services Warranty Period will not be later than three (3)
months from the date the Vendor would have otherwise been able to commence
Substantial Completion testing in such PCS System in accordance with Exhibit B3
and Milestone 8 as set forth on Exhibit A1 but for the existence of such
Microwave Delay Period) (the "Facilities Preparation Services Warranty Period"
and collectively with the RF Services Warranty Period, the "Services Warranty
Periods") such Facilities Preparation Services will be (i) operational in
accordance with the Specifications, (ii) in compliance with all material
Applicable Laws and material Applicable Permits in effect at the time of the
completion of such Facilities Preparation Services in such PCS System, and (iii)
free from Defects or Deficiencies.

     (c)  The Vendor warrants that, for a period of six (6) months from the date
of completion, with respect to other Services performed by the Vendor and not
otherwise covered elsewhere in this Section 17, including, but not limited to,
repair Services, such other Service(s) will be free from Defects or Deficiencies
for which the Vendor is responsible pursuant to the terms of this Contract.

     17.3  System Warranty.  The Vendor warrants that, for a period ending three
           ---------------
(3) years from the Final Acceptance of the last PCS System within the Initial
System (the "System Warranty Period"), the ongoing performance of each PCS
System together with all other PCS Systems within the System will conform with
and perform to the performance criteria set
<PAGE>

                                                                              73

forth Exhibit F as of the date of the Final Acceptance of such PCS System based
on the circumstances within such PCS System on such date.  The System warranty
pursuant to this subsection 17.3 will be limited to the extent that the
projections of subscriber growth, traffic and other predictive data, including
all applicable standards as identified in Exhibits B1, D and H, upon which the
Final Site Count and Final RF Design have been determined, have not been
materially exceeded or the applicable and relevant industry standards have not
materially changed.

     17.4  Breach of Warranties.  (a) In the event of any breach of any of the
           --------------------
Warranties during any of the applicable Warranty Periods set forth in
subsections 17.1(a), 17.1(b), 17.2(a), 17.2(b), 17.2(c) and 17.3, the Vendor
will, in accordance with the terms of this Section 17, promptly repair or
replace the defective or nonconforming Product or otherwise cure any Defects and
Deficiencies so that each PCS System and the System as a whole will perform in
accordance with the Specifications and Exhibit F. If the Vendor fails to
promptly repair, replace and/or cure such defect, the Owner may, in addition to
exercising any other remedies available to it, itself cause such repair,
replacement and/or cure, at its option and at the sole cost and expense of the
Vendor.

     (b)  The Vendor recognizes that the Owner may suffer injury and may be
damaged in an amount which will be difficult to determine with certainty as a
result of Outages resulting from causes attributable to the failure of the
Vendor's Products and/or Services to perform in accordance with the
Specifications.  As used herein, "Outage" means an unscheduled loss of
functionality of the System or any PCS System due to the failures of PCS
Products or any combination thereof defined as the loss of the capability to
originate or terminate [ ] or more of the active voice channels then in service
within the System or such PCS System for a period of time exceeding [ ] minutes.

     (c)  During the System Warranty Period, the Vendor will be liable to the
Owner for damages (the "Warranty Damages") for Outages (for other than in the
Test-bed Laboratory) that result from (i) the failure of the Vendor's Equipment
and/or Software to perform in accordance with the Specifications, (ii) the
failure of the Vendor to provide Services in accordance with the Specifications
applicable thereto, (iii) a Vendor procedural error or (iv) inaccurate Technical
Documentation, excluding marketing bulletins, sales literature or other
promotional materials provided by the Vendor to the Owner. As used herein,
"Vendor procedural error" means an error or improper deviation from the Vendor's
or its Subcontractors' procedures by, or attributable to, the Vendor's
personnel.  Warranty Damages will be calculated based upon [   ] for each Outage
occurring in any given PCS System to the extent such Outage exceeds [   ] from
the time the Owner notified the Vendor of such Outage (not including such
[   ]), plus [   ] for each minute the duration of the Outage exceeds [   ]from
the time the Owner notifies the Vendor of such Outage (not including such [  ]).

     (d)  In no event will the Vendor's liability for Warranty Damages pursuant
to this subsection 17.4 exceed [   ] with respect to each Outage in any given
PCS System. In addition, the Vendor's total liability for Warranty Damages

<PAGE>

                                                                              74

pursuant to this subsection 17.4 will not exceed [   ] per calendar year during
the Term of this Contract with respect to Outages in any given PCS System per
calendar year.

     (e)  Notwithstanding the foregoing, the Vendor will have no liability
pursuant to this subsection 17.4 for:

                         (i)   Outages caused by a Force Majeure event as
               described in Section 16 other than to the extent that any of the
               Vendor's Products and/or Services resulting in such Outages
               should, in accordance with the Specifications be able to
               withstand any such Force Majeure event;

                         (ii)   Outages resulting from a scheduled activity,
               including, but not limited to, System maintenance or loading of
               Software or Equipment Upgrades, Enhancements or Combined
               Releases, unless said Outage (without fault of the Owner) extends
               beyond the expected downtime, as provided in the Specifications
               applicable thereto, associated with such Equipment or Software
               maintenance Upgrades, Enhancements or Combined Releases;

                         (iii)    alterations by the Owner and/or the Vendor at
               the Owner's request or otherwise pursuant to the terms of this
               Contract to the System and/or any PCS System, excluding normal
               maintenance or parameter changes as prescribed by the applicable
               Technical Documentation;

                         (iv)   Outages resulting from the Owner's, its
               subcontractors' or any third party's (if such third party is
               employed by the Owner) failure to follow the Technical
               Documentation;

                         (v)   Outages resulting from the negligence, gross
               negligence or willful misconduct of the Owner, or any of its
               employees, agents or contractors or any other third party (other
               than any Subcontractor or any employees, representatives or
               agents of the Vendor); or

                         (vi)   Outages resulting from failure of equipment or
               software not supplied by the Vendor or any Subcontractors or from
               the performance of services not performed by the Vendor or any
               Subcontractors; or

                         (vii)    Outages caused by the Owner's deactivation of
               the System or any portion thereof, unless the deactivation is
               undertaken in avoidance of an unplanned outage; or

                         (viii)    Outages caused by the failure of the Network
               Interconnection facilities.

     (f)  On or before the beginning of each quarter of each calendar year
during the Term of this Contract, the Owner will provide the Vendor a written
report summarizing any Outages occurring during the previous calendar quarter.
The amount of any Warranty
<PAGE>

                                                                              75

Damages will be determined by the Owner as of the end of the fourth quarter of
each calendar year during the Term, for the preceding four quarterly reporting
periods during such Term.  The Owner will notify the Vendor of any such Warranty
Damages in writing.  Such Damages will be payable in credits on future purchases
under this Contract or otherwise if this Contract is terminated for any reason
within thirty (30) days of the occurrence.  Any disputes regarding the
determination of the cause of an Outage or the amount of any such Warranty
Damages will be resolved in accordance with the provisions of Section 23.

     17.5  Repair and Return. (a)  If the Owner claims a breach of warranty
           -----------------
under subsections 17.1, 17.2 or 17.3, it must notify the Vendor of the claimed
breach within a reasonable time after its determination that a breach has in
fact occurred.  The Owner will allow the Vendor to inspect the Products, the
Services or the System, as the case may be, on-site, or, upon the Vendor's
reasonable request and, subject to subsection 17.5(d) below, at the Vendor's
sole expense: (i) with respect to Products, return such Products to any of the
Vendor's repair facilities located in the United States and listed on Schedule
8, or (ii) with respect to Non-Essential Equipment, return such Non-Essential
Equipment to the Vendor (or to the third party manufacturer if previously
requested by the Vendor) for further return to the applicable third party
manufacturer. The Vendor or such third party manufacturer may use either new,
remanufactured, reconditioned, refurbished, or functionally equivalent Products
or parts pursuant to the terms of this Contract, including, but not limited to,
the Specifications, in the furnishing of warranty repairs or replacements under
this Contract.

     (b)  The Vendor agrees to commence work on all such Products, Non-Essential
Equipment, Services or any System Defect, as the case may be, or Installation
defects as soon as practicable, but the Vendor will use reasonable efforts to
commence such Work in no event later than twenty-four (24) hours after
notification of such defect, and, subject to subsections 17.5(e) and 17.5(f),
the Vendor will cure such defect as promptly as practicable.  During the Product
Warranty Period electronic circuit board components of Equipment or Non-
Essential Equipment, as the case may be, will be repaired or replaced by the
Vendor.

     (c)  Failure of the System to function to the level of the performance
warranty as set forth in subsection 17.3 will result in the obligation of the
Vendor to promptly make whatever repairs, modifications, alterations, expansions
or to take any other action of any kind, including but not limited to the
provision of additional Products and/or Services, necessary to satisfactorily
fix that portion of the System causing any failure for which the Vendor is
responsible.  In the event of a breach of the warranties in Section 17 which
will be cured with the installation of additional PCS Products, the Vendor will
provide such PCS Products, together with related transportation, Installation
and optimization Services, as are reasonably required to remedy the shortfall,
at no charge to the Owner, provided that, if in order to remedy the shortfall,
                           -------- ----
the number of additional Base Stations required to cure the Vendor's breach
under these warranties is not in excess of five percent (5%) of the total number
of Base Stations in the relevant PCS System (as such "total number" is as set
forth in the Final RF Engineering Plan), the Vendor will not be obligated to pay
for the Base Stations and the installation and transportation related thereto
required to cure such breach, provided further that the Vendor will be obligated
                              -------- ------- ----
to provide and pay for any Base Stations and the installation and transportation
related thereto in excess of any such five percent (5%) shortfall.

     (d)  All costs associated with (i) removing or disconnecting the Products
or the Non-Essential Equipment subject to the warranty claim pursuant to the
terms of this Section 17 from any other Products, the respective PCS System or
any part thereof or from other equipment, any other pcs system or any part
thereof to which they are attached or connected, or (ii) dismantling surrounding
Products, the respective PCS System or any part thereof or any other equipment
or other pcs system or any part thereof in order to so remove or disconnect the
Products or Non-Essential Equipment subject to such warranty claim will be borne
by the Vendor throughout the applicable Warranty Period unless such Products are
readily returnable to the Vendor in which case the Owner will bear all such
costs.  All packaging, shipping and freight charges incurred in connection with
the return of Items to the Vendor will be borne by the Owner.  The Vendor will
be responsible for packing, shipping and freight charges for return of repaired
or replacement Items to the Owner, unless the Products or Non-Essential
Equipment, as the case may be, returned are not Defective or otherwise not
covered by the Vendor's warranty pursuant to subsection 17.1, in which case the
Owner will pay for all such charges between the Owner's point of origin and the
Vendor's applicable repair facility in the United States.

     (e)  For routine warranty service, the Vendor will, during the respective
Warranty Period, ship replacement or repaired Products or Non-Essential
Equipment (or components thereof) within thirty (30) days of receipt of the
Defective Equipment or Non-Essential Equipment (or components thereof) from the
Owner.  In the event such replacement or repaired Products or Non-Essential
Equipment cannot be shipped within such time period, or if the Vendor determines
that due to the particular circumstances, on-site repairs or services are
required, the Vendor will undertake such repairs or replacement services on-site
within thirty (30) days of notification of the warranty Defect by the Owner.  In
the event that the Vendor fails to repair or replace Defective Products and/or
Non-Essential Equipment within thirty (30) days from the Owner's notice to the
Vendor, then the Vendor will be deemed to be in breach of its obligations
pursuant to this Contract and the Owner will be entitled to receive a refund of
all amounts previously paid to the Vendor for the Defective Products or Non-
Essential Equipment, and will have no further obligation to pay additional
amounts in connection with the Defective Products or Non-Essential Equipment.
The Owner will return such Defective Products and Non-Essential Equipment to the
Vendor at the Vendor's sole cost and expense.

     (f)  For emergency warranty service situations, the Vendor will, during the
applicable Warranty Periods, use its best efforts to ship replacement Products
or Non-Essential Equipment (or components thereof) no later than twelve (12)
hours after notification of the warranty Defect by the Owner.  The Owner will
ship the Defective Products or Non-Essential Equipment to the Vendor within
thirty (30) days of receipt of the replacement Products or Non-Essential
Equipment, as the case may be.  In the event the Vendor fails to receive such
Defective Products or Non-Essential Equipment within such thirty (30) day
period, the Vendor will invoice the Owner for the replacement Products or Non-
Essential Equipment at the then-current price in effect therefor pursuant to the
terms of this Contract.  If in an emergency warranty service situation, the
Owner and/or the Vendor determines that due to the particular circumstances, on-
site technical assistance is necessary, the Vendor will dispatch emergency
service personnel to the site in accordance with the terms of subsection 2.26.

the manufacture of any part of the System or the performance of any of the
Services to be provided hereunder from a third party, the warranties given to
the Vendor by such third party will inure, to the extent assigned to the Owner
pursuant to this Section 17 or permitted by law, to the benefit of the Owner,
and the Owner will have the right, at its sole discretion, to enforce such
warranties directly and/or through the Vendor. The warranties of such third
parties will be in addition to and will not, unless otherwise expressly stated
herein, be in lieu of any warranties given by the Vendor under this Contract.

     17.10  Additional System Element Locations.  In the event that under the
            -----------------------------------
remedy provisions of this Section 17  the Vendor is required to provide
additional MSC and/or Base Stations requiring additional System Element

exemption certificate applicable thereto or pay to the Vendor, upon presentation
of invoices therefor, such amounts thereof as the Vendor may by law be required
to collect or pay; provided, however, that the Vendor will use its best efforts
                   --------  -------
to minimize the amount of any such taxes.  The Owner has no obligation to the
Vendor with respect to other taxes, including, but not limited to, those
relating to franchise, net or gross income or revenue,

     SECTION 20  INDEMNIFICATION AND LIMITATION OF LIABILITY

     20.1  Vendor Indemnity.  (a)  The Vendor will indemnify and hold the Owner
           ----------------
and its Affiliates, partners, directors, officers, agents and employees (the
"Indemnitees") harmless from and against all third party claims, demands suits,
proceedings, damages, costs, expenses, liabilities (including, without
limitation, reasonable legal fees) or causes of action (collectively,
"Liabilities") brought against or incurred by any Indemnitee for (i) injury to
persons (including physical or mental injury, libel, slander and death), or (ii)
loss or damage to any property, or (iii) violations of Applicable Laws,
Applicable Permits, codes, ordinances or regulations by the Vendor, or (iv) any
patent or trademark claims arising out of the Vendor's obligation subject to
subsection 14.2 or (v) any other liability, resulting from the acts or
omissions, negligence, error, wilful misconduct or strict liability, of the
Vendor, its officers, agents, employees, or Subcontractors in the performance of
this Contract.  If the Vendor and the Owner jointly cause such Liabilities, the
Parties will share the liability in proportion to their respective degree of
causal responsibility.

     (b)  The Vendor's obligation to indemnify under subsection 20.1(a) with
respect to any Liability will not arise unless the Owner or the Indemnitee (i)
notifies the Vendor in writing of such potential Liability, in the case of the
Owner, within a reasonable time after the Owner will receive written notice of
such Liability; provided that the lack of such notice will not affect the
                -------- ----
Vendor's obligation hereunder (A) if the Vendor otherwise has knowledge of such
Liability and (B) unless such lack of notice is the cause of the Vendor being
unable to adequately and reasonably defend such Liability, (ii) gives the Vendor
the opportunity and authority to assume the defense of and settle such
Liability, subject to the provisions of the next two sentences, and (iii)
furnishes to the Vendor all such reasonable information and assistance available
to the Owner (or other Indemnitees) as may be reasonably requested by the Vendor
and necessary for the defense against such Liability.  The Vendor will assume on
behalf of the Indemnitee and conduct with due diligence and in good faith the
defense of such Liability with counsel (including in-house counsel) reasonably
satisfactory to the Indemnitee; provided that the Indemnitee will have the right
                                -------- ----
to be represented therein by advisory counsel of its own selection and at its
own expense.  If the Indemnitee will have reasonably concluded that there may be
legal defenses available to it which are different from or additional to, or
inconsistent with, those available to the Vendor, the Indemnitee will have the
right to select separate counsel reasonably satisfactory to the Vendor to
participate in the defense of such action on its own behalf at the Vendor's
expense.  In the event the Vendor fails to defend any Liability as to which an
indemnity might be provided herein, then the Indemnitee may, at the Vendor's
expense, contest or settle such matter without the Vendor's consent.  All
payments, losses, damages and reasonable costs and expenses incurred in
connection with such contest, payment or settlement will be to the Vendor's
account and may be deducted from any amounts due to the Vendor.  The Vendor will
not settle any such Liability without consent of the Indemnitee, which consent
will not be unreasonably withheld.  This indemnity is in lieu of all other
obligations of the Vendor, expressed or implied, in law
<PAGE>

                                                                              80

15.2, 15.3, 17.4, 20.1, AND 20.3 HEREOF, IN NO EVENT, AS A RESULT OF BREACH OF
CONTRACT OR BREACH OF WARRANTY, WILL EITHER PARTY HERETO BE LIABLE UNDER THIS
CONTRACT TO THE OTHER PARTY FOR ANY CONSEQUENTIAL OR INCIDENTAL DAMAGES,
INCLUDING LOST PROFITS OR REVENUES OF SUCH PARTY, BEFORE OR AFTER ACCEPTANCE,
WHETHER OR NOT SUCH DAMAGES ARE FORESEEABLE.

     20.3  Damages for Fraud or Willful Misconduct  (a)  The Vendor will be
           ---------------------------------------

and consequential damages, incurred by the Owner as a result of any damage or
injury caused by or resulting from the fraud or willful misconduct of the
Vendor.

     (b)  The Vendor will be responsible for all damages, but excluding
indirect, incidental and consequential damages, incurred by the Owner as a
result of any damages or injury caused by or resulting from the fraud, gross
negligence or willful misconduct of any of the Subcontractors related to the
performance of the Work, to the extent the Vendor would have liability therefor
under this Contract if the Vendor had engaged in such conduct.

     SECTION 22  TITLE AND RISK OF LOSS


     22.1  Title.  Title to each Item of Equipment (but in no case Software)
           -----
will pass to the Owner upon delivery thereof by the Vendor to the System Element
Location to which each such Item belongs or such other location specifically
requested by the Owner or as otherwise mutually agreed to by the Parties.  Prior
to acquiring title to the Equipment, the Owner will not cause or permit the
Equipment to be sold, leased or subjected to a lien or other encumbrance.

     22.2  Risk of Loss.  Risk of loss of any Products furnished to the Owner in
           ------------
connection with this Contract will pass from the Vendor to the Owner upon the
completion of the Bolt-down by the Vendor of any PCS Product or at the
completion of installation of any other Product each at the appropriate System
Element Location within the given PCS System provided that the risk of loss of
any given PCS System within the System will not pass to the Owner until such
time as the Vendor is fully prepared to commence testing for the Substantial
Completion of such PCS System in accordance with and pursuant to Exhibit B3 and
Exhibit A1; provided, however, that the Owner will assume the risk of loss prior
            --------  -------
to such Substantial Completion by the Vendor for any such Products damaged due
to the gross negligence or willful misconduct of the Owner (provided that the
                                                            -------- ----
Owner will also assume the risk of loss for its own negligence at any time after
Milestone 6 (as set forth in Exhibit A1) in each PCS System within the System).
With respect to Products delivered by the Vendor but not otherwise installed by
the Vendor pursuant to and in accordance with the terms of this Contract, risk
of loss will pass to the Owner upon delivery by the Vendor to the Owner's
designated site.  Until such time as risk passes to the Owner, the Vendor will,

                                 -------- ----
loss to the Owner, any actual proceeds of its
<PAGE>

                                                                              83

          SECTION 23  DISPUTE RESOLUTION

     23.1  Dispute Resolution.  Subject to subsection 24.3 and subsection 23.4,
           ------------------
in the event any controversy, claim, dispute, difference or misunderstanding
arises out of or relates to this Contract, any term or condition hereof, any of
the Work to be performed hereunder or in connection herewith, the respective
System Managers of the Owner and the Vendor will meet and negotiate in good
faith in an attempt to amicably resolve such controversy, claim, dispute,
difference or misunderstanding in writing.  Such System Managers must meet for
this purpose within ten (10) Business Days, or such other time period mutually
agreed to by the Parties, after such controversy, claim, dispute, difference or
misunderstanding arises.  If the Parties are unable to resolve the controversy,
claim, dispute, difference or misunderstanding through good faith negotiations
within such ten (10) business day period, each Party will, within five (5)
Business Days after the expiration of such ten (10) business day period, prepare
a written position statement which summarizes the unresolved issues and such
Party's proposed resolution.  Such position statement must be delivered by the
Vendor to the Owner's Vice President of Engineering or Operations and by the
Owner to the Vendor's corresponding officer or representative for resolution
within (5) Business Days, or such other time period mutually agreed to by the
Parties.

     If the Parties continue to be unable to resolve the controversy, claim,
dispute, difference or misunderstanding, either Party may initiate arbitration
in accordance with the provisions of subsection 23.2 below; provided, however,
                                                            --------  -------
that with respect to any controversy, claim, dispute, difference or
misunderstanding arising out of or relating to this Contract by which either
Party seeks to obtain from the other monetary damages in excess of twenty-five
million dollars ($25,000,000), either Party, in such case, may commence an
action in any state or federal court in accordance with subsection 27.7 to
resolve such matter in lieu of proceeding with an arbitration pursuant to and in
accordance with subsection 23.2.  The arbitrators hired or otherwise chosen
pursuant to and in accordance with the terms of this Contract will determine
issues of arbitrability pursuant to the terms of this Contract but may not in
any way limit, expand or otherwise modify the terms of this Contract nor will
they have any authority to award punitive or other damages in excess of
compensatory damages (other than as specifically set forth in this Contract) and
each Party irrevocably waives any such claim thereto when invoking the
arbitration provisions of subsection 23.2.

          23.2  Arbitration.  An arbitration proceeding initiated by either
                -----------
Party under this Contract with respect to any controversy, claim, dispute,
difference or misunderstanding will be conducted in Kansas City, Missouri in
accordance with the Commercial Arbitration rules of the AAA, except that, at the
request of either Party, a stenographic transcript of the testimony and
proceedings will be taken and the arbitrators will base their decision upon the
records and briefs of the Parties.
<PAGE>

                                                                              84

     Such arbitration will be initiated by either Party by notifying the other
Party in writing and will be settled before three (3) impartial arbitrators, one
of whom will be named by the Owner, one by the Vendor and the third by the two
arbitrators appointed by the Owner and the Vendor, respectively.  All of the
named arbitrators will have significant experience in the wireless
telecommunications industry.  If either the Owner or the Vendor fails to select
an arbitrator within ten (10) days after notice has been given of the initiation
of the arbitration, the officer in charge of the Kansas City, Missouri office of
the AAA will have the right to appoint the other arbitrator, and the two
arbitrators thus chosen will then select the third arbitrator.

     Except as the Parties may otherwise mutually agree, the arbitration
hearings will commence within fifteen (15) Business Days after a Party's
initiation of the arbitration.  The Federal Rules of Evidence will apply and
reasonable discovery, including depositions, will be permitted.  Discovery
issues will be decided by the arbitrators and post-hearing briefs will be
permitted.

     The arbitrators will render a decision within ten (10) days after the
conclusion of the hearing(s) and submission of post-hearing briefs and a written
opinion setting forth findings of fact and conclusions of law will be made
available to the Parties within that time period.  The decision of the majority
of the arbitrators regarding the matter submitted will be final and binding upon
the Parties.  Judgment upon the award rendered by the arbitrators may be entered
in any court having jurisdiction thereof.

     Each Party will pay for the services and expenses of the arbitrator
appointed by it, its witnesses and attorneys, and all other costs incurred in
connection with the arbitration (including, without limitation, the cost of the
services and expenses of the arbitrator appointed by the two arbitrators
appointed by the Parties) will be paid in equal part by the Parties, unless the
award will specify a different division of the costs.  Unless otherwise
specifically stated in this Contract, during the pendency of any arbitration
proceedings, the Parties agree to continue to perform their obligations
hereunder in the same manner as prior to the institution of arbitration
proceedings.

     23.3  Third Party Engineer.  Disputes arising under subsections 2.6, 2.7,
           --------------------
9.5(b), 9.6, 10.1  and 17.4 of this Contract, or as otherwise specifically
provided elsewhere in this Contract, or as otherwise mutually agreed by the
Parties, are to be resolved by the Third Party Engineer in the manner provided
in this subsection 23.3. The Vendor and the Buyer will first attempt to resolve
the dispute through consultation and negotiation in good faith and in a spirit
of mutual cooperation as provided in subsection 23.1 above. If those attempts
fail, then either Party may submit its written notice to the other Party
requesting that the dispute be resolved by the Third Party Engineer, in
accordance with the merits of the dispute. If, within ten (10) Business Days
after the receipt of such notice by the notified Party, the dispute is not
resolved, the Owner will select one of the Third Party Engineers listed on
Schedule 14 to render decision in the dispute. The Third Party Engineer will
issue a written decision containing an explanation of how and why the decision
was reached. The Third Party Engineer's decision will be final and binding,
except with respect to any opinion that over the Term of the Contract will
impact the losing Party in the amount of one million dollars
<PAGE>

                                                                              85

($1,000,000) or more.  If within ten (10) Business Days following the issuance
of any such opinion the Parties have not agreed to implement the terms of any
such opinion that is not final, either Party may seek arbitration pursuant to
the provisions of subsection 23.2 above.  In such arbitration, either Party may
introduce into evidence the opinion of the Third Party Engineer, but the
arbitrator(s) must rule on all issues of the dispute on a de novo basis, except
                                                          -------
as to any facts or other matters set forth in the opinion and stipulated by both
of the Parties.  If none of the listed Third Party Engineers is available or if
none accepts the assignment and the Parties cannot otherwise mutually agree to
another Third Party Engineer, an experienced and reputable engineer (who is not
employed by either Party or any of their Affiliates or affiliates) will be
chosen by the then President of the Institute of Electrical and Electronic
Engineers (or the Vice President, if the President is a present or former
employee of any such entities) to serve as the Third Party Engineer for the
purposes of resolving the dispute.  Unless otherwise mutually agreed by the
Parties, any Person who is an officer or employee, agent, Subcontractor or
subcontractor of, or a technical consultant to, either Party will be
automatically ineligible to be the Third Party Engineer.   The costs of
utilizing a Third Party Engineer to resolve disputes under this subsection 23.3
will be shared equally by both Parties.

     23.4  Other Remedies.  Notwithstanding anything to the contrary herein
           --------------
contained, each Party will be entitled to pursue any equitable rights and
remedies that are available at law or in equity without complying with
subsection 23.2 or 23.3.

     23.5  Tolling.  All applicable statutes of limitation will be tolled to the
           -------
extent permitted by Applicable Law while the dispute resolution procedures
specified in this Section 23 are pending, and nothing herein will be deemed to
bar any Party from taking such action as the Party may reasonably deem to be
required to effectuate such tolling.

Owner; provided that in such case the Owner will have the right, but not the
       -------- ----
obligation, to terminate this Contract with respect to only that PCS System in

not the obligation, to terminate this Contract in its entirety as otherwise set
forth in this subsection 24.2; or

     (m)  the Vendor otherwise materially breaches any provision of this
Contract.

     24.3  Remedies.  (a)  If any of the Vendor Events of Default exists, the
           --------
Owner may, without prejudice to any other rights or remedies of the Owner in

     the same is in a partial state of completion or completed condition, and
     title to any of said items vests in the Owner (if not already vested by the
     provisions of this Contract);

               (ii)   Take temporary possession and control of all of the

          (iii)    Direct that the Vendor assign its Subcontractor agreements to
     the Owner without any change of price or conditions therein or penalty or
     payment therefor; or

               (iv)   Take over and finish the Work by whatever reasonable
     methods the Owner may deem expedient;

     24.4  Discontinuance of Work.  Upon such notification of termination, the
           ----------------------
Vendor must immediately discontinue all of the Work (unless such notice of
termination directs otherwise), and, as more fully set forth in subsection

           -----
Default, the Owner will be entitled to the costs in connection with finishing
the Work (exclusive of any Liquidated Damages already paid and/or owing to the

otherwise provided in any provision of this Contract expressly limiting the

prior to the effectiveness of such termination or arising out of its obligations
as to portions of the Work already performed or of obligations assumed by the
Vendor prior to the date of such termination.

     24.8  Vendor's Right to Terminate.  The Vendor will have the option to

state insolvency statutes;

     (c)  the Owner fails to make payments of undisputed amounts due to the

              -------- ----
days after the Vendor has notified the Owner of its right and intent to so
terminate on account of such overdue amount;

     (d)  the Owner persistently and materially breaches subsection 11.1 or
subsection 27.19 notwithstanding the fact that the Vendor will have provided the
Owner with prior written notice describing the alleged material breaches and
will have given the Owner a reasonable time (not less than thirty (30) days) to
cure any such breaches; or

     (e)  except as otherwise provided in subsection 24.1 the Owner fails to

Owner's build-out of the initial phase of the Nationwide Network has not been
finalized with the Vendor and the Other Vendors on terms and conditions
reasonably satisfactory to the Owner, on or before one hundred and eighty (180)
days after the Effective Date, the Owner will have the right, but not the
obligation, to terminate this Contract in its entirety without charge or penalty
of any kind.  In the event of a termination of this Contract pursuant to this
subsection 24.9 the Owner will remain liable for amounts due to the Vendor for
all Work performed

                                                                              90

or Products delivered by the Vendor or any of its Subcontractors pursuant to the
specific terms of this Contract which had been directly delivered to or
performed for the Owner and/or any of its facilities or sites in accordance with
the terms of this Contract including, but not limited to, the Project
Milestones. Any amounts owed by the Owner for Work done or Products delivered by
the Vendor during such interim one hundred and eighty (180) day period (the
"Financing Interim Period") not otherwise invoiced to the Owner by the Vendor
prior to the termination of such Financing Interim Period, will be invoiced to
the Owner by the Vendor within thirty (30) days (but failure to so invoice will
not excuse the Owner's obligation to otherwise pay the Vendor pursuant to the
terms of this subsection 24.9(a)) of such termination pursuant to this
subsection 24.9(a) and will be payable to the extent not otherwise in dispute by
the Owner within thirty (30) days of receipt of such invoice; provided that in
                                                              -------- ----
no event will the Owner be liable to the Vendor due to a termination
of this Contract pursuant to this subsection 24.9(a) for any of the Vendor's
direct or indirect costs or expenses incurred in connection with any supplies or
equipment ordered by the Vendor or agreements entered into by the Vendor in
order to enable it to fulfill its obligations hereunder or in connection with
the establishment of and/or upgrade to its manufacturing, personnel,
engineering, administrative or other capacities and/or resources in
contemplation of or pursuant to its performance in accordance with the terms of
this Contract and any amounts due to the Vendor pursuant to this subsection
24.9(a) will be limited in all cases to Work actually done or Products or
Services actually delivered to the Owner, its sites or its facilities.

     (b)  If at any time after the Effective Date any material change will have
occurred in any Applicable Law or in the interpretation thereof by any
Governmental Entity, or there will be rendered any decision in any judicial or
administrative case, in either case which, in the reasonable opinion of the
Owner, would make the Owner's use of any part of any PCS System illegal or would
subject the Owner or any of its Affiliates to any material penalty, other
material liability or onerous condition or to any burdensome regulation by any
Governmental Entity or otherwise render the use of such PCS System economically
nonviable, then, with respect to such PCS System, or affected part thereof, or
with respect to the entire System if so affected, the Owner may terminate this
Contract without charge or penalty of any kind; provided that (i) the Owner
                                                -------- ----
gives the Vendor prior written notice of any such change or decision; (ii) that
the Owner uses its reasonable efforts for a reasonable time to reverse or
ameliorate such change or decision to the extent possible or practical prior to
declaring such termination and (iii) the Owner, at the Vendor's request, gives
the Vendor a legal opinion from a reputable law firm with experience in the area
confirming the Owner's reasonable opinion as set forth above.  In the event of a
termination pursuant to this subsection 24.9(b), payment obligations incurred by
the Owner for Work actually done or Products or Services actually delivered by
the Vendor prior to such termination pursuant to this Contract will be payable
by the Owner to the Vendor on the same terms and subject to the limitations set
forth in subsection 24.9(a) above.

          SECTION 25  SUSPENSION

     25.1  Owner's Right to Suspend Work.  The Owner may, at any time and upon
           -----------------------------
reasonable notice to the Vendor, order the Vendor, in writing, to suspend all or
any part of the Work for such reasonable period of time as the Owner may
reasonably determine to be appropriate for its convenience.  Any request by the
Vendor for a change in the Specifications caused by the Owner's suspension of
the Work pursuant to this subsection 25.1 will be subject to the review and
reasonable acceptance of the Owner.  No modification to the Specifications will
be made to the extent that performance is, was or would have been suspended,
delayed or interrupted for any other cause due to the Vendor's fault or if the
suspension had no effect on agreed upon performance deadlines and/or Project
Milestones set forth in this Contract.  In the event of any such suspension, the
Vendor will be compensated for any actual and reasonable loss, actual and
reasonable damages or actual and reasonable expenses arising directly from such
delay, including but not limited to payments contractually required under any
Subcontractor agreements and reimbursement of reasonable expenses associated
with the necessary re-deployment of the Vendor's resources; provided that the
                                                            -------- ----
Vendor will in such event use reasonable efforts to estimate and report to the
Owner any such costs or expenses prior to the commencement of any such Owner
suspension pursuant to this subsection 25.1.


     SECTION 26  MOST FAVORED CUSTOMER

     26.1  Most Favored Customer Status.  (a)  With respect to the deployment of
           ----------------------------
the Initial System (including any Expansions or additions to the Initial System
within the context of the Initial System pursuant to the terms of this
Contract), the Owner will be deemed one of the Vendor's most important and
favored Customers and will always receive priority in terms of availability and
quantity of Products, Engineering and Services no less favorable than any other
Customer of the Vendor and in any event always in accordance with the terms of
this Contract, including, but not limited to, Exhibit A2. At any time during the
Term, the Owner will receive PCS Products, Engineering and Services at prices
and on payment terms and all other contract terms, including financing terms, no
less favorable to the Owner (when viewed collectively) than those offered or
available to any other Customer (other than Initial Affiliates and/or Additional
Affiliates pursuant to the terms of this Contract) of the Vendor for use of such
Items within the Unites States who are involved in transactions and/or
arrangements of similar or lesser volumes (for the purposes hereof, the Owner's
volume will always be deemed to be at least the level of the Initial Commitment
plus any more PCS Products, Services and/or Engineering ordered at such time
- - - ----
during the Term of this Contract.)

     (b)  On an annual basis throughout the Term of this Contract commencing on
the Effective Date the Vendor will be required to audit its offering of all CDMA
PCS Products, engineering and services provided to the then-existing ten (10)
largest of its Customers (other than Initial Affiliates and/or Additional
Affiliates pursuant to the terms of this Contract) (based on volume purchased or
to be purchased) in the preceding calendar year and certify to the Owner in a
certificate executed by a duly authorized officer of the Vendor (the "MFC
Certificate") that the Owner has in fact received the prices, payment and other
contract terms,
<PAGE>

                                                                              92

availability and quantity of and on Products, Engineering and Services in
accordance with the terms of clause (a) above.

     (c)  To the extent the Owner determines pursuant to clause (b) above, or
otherwise, that the Vendor has not in fact complied with the terms of clause (a)
above the Owner will have thirty (30) Business Days from receipt of the MFC
Certificate to provide the Vendor with a written claim for Product and/or
Engineering and/or Service pricing rebates on future purchases under this
Contract based upon the Owner's reasonable calculation of the impact on the
Owner of the Vendor's failure to comply with clause (a) of this subsection 26.1.
The Owner's written claim will specify the reasoning underlying its claim.  To
the extent the Vendor disagrees with any such claim for such pricing rebates
made by the Owner pursuant to this clause (c) the Vendor will have the right
within ten (10) Business Days of receiving the Owner's written rebate claim to
request management escalation of the matter as provided in subsection 23.1.  In
the event that the Parties have not resolved the matter within ten (10) Business
Days after commencement of such escalation, either Party will have the right to
submit the Owner's claim and the Vendor's written response thereto to an
Independent Auditor who will have the authority only to determine whether the
Vendor is in non-compliance with the terms of clause (a) above and whether the
Owner's calculation of the claimed pricing rebate is fair and reasonable in
light of the Vendor's non-compliance with the terms of clause (a) above.  Any
such independent determination will be made upon specific procedures and a set
of factors mutually agreed by the Parties.  The Vendor will provide to the
Independent Auditor records and summaries of its agreements with such ten (10)
largest Customers pursuant to and in accordance with the terms of this
subsection 26.1.  The Independent Auditor's determination must be made and
delivered to both the Vendor and the Owner within ten (10) Business Days of
receiving the request from the Vendor.  The report of the Independent Auditor
will not be determinative of the Owner's right to pricing rebates under this
clause, and any dispute between the Vendor and the Owner as to such matter after
the Independent Auditor has rendered its opinion may be referred to arbitration
as provided in subsection 23.2; provided that the report of such Independent
                                -------- ----
Auditor will be admissible as evidence in any such arbitration.  The Party
requesting a determination by an Independent Auditor will bear the cost of the
auditor, provided that, if the other Party's position is not supported by the
         -------- ----
Independent Auditor, such other Party will bear any such cost.


     SECTION 27  MISCELLANEOUS

     27.1  Amendments.  The terms and conditions of this Contract, including the
           ----------
provisions of Exhibits and Schedules hereto, may only be amended by mutually
agreed contract amendments.  Each amendment must be in writing and will identify
the provisions to be changed and the changes to be made.  Contract amendments
must be signed by duly authorized representatives of each of the Vendor and the
Owner.

     27.2  Owner Liabilities.  The Parties understand and agree that none of the
           -----------------
Partners, nor any of their Affiliates, will guarantee or otherwise be in any way
liable with respect to any obligations or liabilities of the Owner or any of its
subsidiaries pursuant to this Contract.  The Parties further understand and
agree that neither the Owner nor any of its subsidiaries
<PAGE>

                                                                              93

will guarantee or otherwise be in any way liable for any obligations or
liabilities of any of the Partners or any Affiliate of the Owner pursuant to
this Contract unless, and only to the extent, (i) the Owner or any one of its
subsidiaries in accordance with the Owner's direction expressly agrees in
writing to guarantee or otherwise be liable for such liability, or (ii) in the
case of an Affiliate, such Affiliate orders Products and/or Services through the
Owner pursuant to the terms of this Contact.

     27.3  Offset.  The Vendor hereby waives any right of offset of amounts owed
           ------
by the Owner to the Vendor pursuant to the terms of this Contract.

     27.4  Assignment.  Except as otherwise permitted herein, neither this
           ----------
Contract nor any portion hereof may be assigned by either Party without the
express prior written consent of the other Party provided that such consent will
                                                 -------- ----
not otherwise be unreasonably withheld (provided further that the Owner's
                                        -------- ------- ----
reasonable concern about an assignee's ability to perform the obligations and/or
the Work of the Vendor pursuant to and in accordance with the terms of this
Contract will be deemed to be reasonable grounds for the Owner withholding any
such consent).  The Owner may, without the consent of the Vendor, collaterally
assign its rights hereunder (including, but not limited to, all licenses with
respect to the Software) to any or all parties providing financing for any part
of the Nationwide Network under a collateral trust for the benefit of the Vendor
and one or more other entities providing financing for any part of the
Nationwide Network or similar arrangement for the benefit of the Vendor and one
or more other entities providing for the financing for any part of the
Nationwide Network, in either case, which collateral trust or similar
arrangement, as the case may be, is reasonably acceptable to the Vendor in
accordance with the terms of the financing documents.  If requested by the
Owner, the Vendor will within seven (7) days of such request provide a written
consent to any such assignment; provided that such consent will permit
                                -------- ----
reassignment if the financing parties exercise their remedies under the
documents for such financing subject to reasonable standards as to (i) the
creditworthiness of the assignee and (ii) the fact that the assignee is not at
such time a competitor of the Vendor.  The foregoing rights and obligations are
in addition to those set forth in subsection 27.21.  Any attempted assignment in
violation of the terms of this Contract will be null and void.

     27.5  Enforcement.  The Parties agree that either Party may enforce the
           -----------
provisions of subsections 11.4 and 27.4 regarding assignment by an action for
injunction or other equitable remedies.

     27.6  Notices.  Any notice, request, consent, waiver or other communication
           -------
required or permitted hereunder will be effective only if it is in writing and

made by mailing or delivering a copy of such process to the Owner or the Vendor,

                                                                              95

will affect the right of the Owner or the Vendor to serve legal process in any
other manner permitted by law.

     27.8  Compliance with Law.  The Owner and the Vendor will (a) comply with
           -------------------
all Applicable Laws in the performance of this Contract, including, without
limitation, the laws and regulations of the United States Department of Commerce
and State Department and any other applicable agency or department of the United

     27.9  Independent Contractor.  All work performed by any Party under this
           ----------------------
Contract will be performed as an independent contractor and not as an agent of
the other and no Persons furnished by the performing Party will be considered
the employees or agents of the other.  The performing Party will be responsible
for its employees' compliance with all laws, rules, and regulations while
performing all work under this Contract.

     27.10  Headings.  The headings given to the Sections and subsections herein
            --------
are inserted only for convenience and are in no way to be construed as part of
this Contract or as a limitation of the scope of the particular Section or
subsection to which the title refers.

     27.11  Severability.  Whenever possible, each provision of this Contract
            ------------
will be interpreted in such a manner as to be effective and valid under such
applicable law, but, if any provision of this Contract will be held to be
prohibited or invalid in any jurisdiction, the remaining provisions of this
Contract will remain in full force and effect and such prohibited or invalid
provision will remain in effect in any jurisdiction in which it is not
prohibited or invalid.

     27.12  Waiver.  Unless otherwise specifically provided by the terms of this
            ------
Contract, no delay or failure to exercise a right resulting from any breach of
this Contract will impair such right or will be construed to be a waiver
thereof, but such right may be exercised from time to time as may be deemed
expedient.  If any representation, warranty or covenant contained in this
Contract is breached by either Party and thereafter waived by the other Party,
such waiver will be limited to the particular breach so waived and not be deemed
to waive any other breach under this Contract.

     27.13  Public Statements and Advertising.  (a)  Neither Party nor its
            ---------------------------------
Subcontractors will issue any public statement (or any private statement unless
required in the performance of the Work), except as stated below, relating to or
in any way disclosing any aspect of the Work, the System, or any PCS System
including the scope, the specific terms of this Contract, extent or value of the
Work and/or the System or any PCS System.  Express written consent of the other
Party is required prior to the invitation of or permission to any reporter or
journalist to enter upon the System or any part thereof.  The Vendor agrees not
to use for publicity purposes any photographs, drawings and/or materials
describing the System or any PCS System without obtaining the prior written
consent of the Owner, which consent will not be unreasonably withheld.  This
subsection 27.13(a) is not intended to exclude the provision of necessary
information to prospective Subcontractors and the Vendor's or the Owner's
<PAGE>

                                                                              96

personnel, agents or consultants.  All other such public disclosures by a Party
require the written consent of the other Party. The obligations of the Parties
under this subsection 27.13(a) are in addition to their respective obligations
pursuant to subsection 27.19. This subsection 27.13(a) will in no way limit
either Party from responding to customary press inquiries or otherwise making
public or private statements not otherwise disclosing Proprietary Information or
the specific terms of this Contract in the normal course of its business and/or
in connection with the Work hereunder.

     (b)  Subject to the last sentence of subsection 27.13(a), each Party will
submit to the other proposed copies of all advertising (other than public
statements or press releases) wherein the name, trademark or service mark of the
other Party or its Affiliates or affiliates is mentioned; and neither Party will
publish or use such advertising without the other Party's prior written
approval. Such approval will be granted as promptly as possible and will not be
unreasonably withheld. The Parties acknowledge that the obtaining of prior
written approval for each such use pursuant to this subsection 27.13(b) may be
an administrative burden. At the request of either Party, the Owner and the
Vendor will establish mutually acceptable guidelines that will constitute pre-
authorization for the uses specified therein. Such guidelines will be subject to
change from time to time at the reasonable request of either Party.

     27.14  Records and Communications.  To the extent not already established,
            --------------------------
promptly after the Work begins, procedures for keeping and distributing orderly
and complete records of the Work and its progress will be established.  The
procedures so established will be followed throughout the course of the Work
unless the Owner and the Vendor mutually agree in advance in writing to revise
the procedures.  Furthermore, immediately after the Notice to Proceed is issued,
complete procedures for communications among the Owner and the Vendor will be
established.  The procedures so established will be followed throughout the
course of the Work unless the Owner and the Vendor mutually agree in advance and
in writing to revise such procedure.

     27.15  Ownership of Specifications.  Neither the Vendor nor any
            ---------------------------
Subcontractor, nor any other Person performing or furnishing the Work, whether
or not under a direct or indirect contract with the Owner, will have or acquire
any title to or ownership rights in any of the Specifications, or in any other
part or portion of this Contract (or copies of any of the Specifications or this
Contract); and no such Person will reuse any of the Specifications on and/or
with respect to any other project without the prior written consent of the
Owner.  The Specifications and this Contract (and any and all copies thereof),
are owned by and title resides in the Owner, unless otherwise agreed between the
Owner and any other Person.  Notwithstanding anything contained herein to the
contrary, the Owner will not acquire any patent, copyright or trade secret
rights as a result of this Contract, except with respect to copyright and trade
secret rights pursuant to licenses and other approvals provided in connection
with the performance of the Work and except to the extent that a non-exclusive
license of any of the Vendor's copyright or trade secret rights is required to
perform the Work.

     27.16  Financing Parties Requirements.  The Vendor acknowledges that the
            ------------------------------
Owner represents that attainment of financing for construction of the Nationwide
Network may be
<PAGE>

                                                                              97

subject to conditions that are customary and appropriate for the providers of
such financing.  Therefore, the Vendor agrees to execute promptly any reasonable
amendment to or modification or assignment of this Contract required by such
providers (including, without limitation, any pertinent industrial development
authority or other similar governmental agency issuing bonds for financing of
the System) which do not materially modify the scope of the Vendor's Work in
order to obtain such financing.  In the event that any such amendment or
modification materially increases the Vendor's risk or costs hereunder, the
Owner and the Vendor will negotiate in good faith to adjust the Contract Price,
and to equitably adjust such other provisions of this Contract, if any, which
may be affected thereby, to the extent necessary to reflect such increased risk
or costs.  In no event will the Vendor be required to accept any modification or
amendment pursuant to this subsection 27.16 which places material increased risk
on the Vendor or otherwise materially modifies the scope of the Vendor's Work,
if, in the Vendor's reasonable opinion, such materially increased risk or
material modification in the Work is not otherwise adequately addressed by the
Owner or otherwise.  The Vendor will be responsible for and pay all costs as a
result of the Vendor's unreasonable refusal to promptly comply with the request
for any such modification or amendment made by any provider of financing
described in this subsection 27.16.

     27.17  Owner Review, Comment and Approval.  To the extent that various
            ----------------------------------
provisions of this Contract provide for the Owner's review, comment, inspection,
evaluation, recommendation or approval, the Owner may at its option do so in
conjunction and/or consultation with the Vendor.  To the extent that this
Contract requires the Owner to submit, furnish, provide or deliver to the Vendor
any report, notice, Change Order, request or other items, the Owner may at its
option and upon written notice to the Vendor designate the Engineer to submit,
furnish, provide or deliver such items as the Owner's agent therefor.  To the
extent that various provisions of this Contract provide that the Owner may
order, direct or make requests with respect to performance of the Work or is
provided access to the System sites or any other site, the Owner may at its
option and upon written notice to the Vendor authorize the Engineer to act as
the Owner's agent therefor.  Upon receipt of such notice, the Vendor will be
entitled to rely upon such authorization until a superseding written notice from
the Owner is received by the Vendor.

     27.18  Specifications.  The Owner acknowledges that parts of the
            --------------
Specifications are comprised of Specifications prepared by the Vendor and that
the Vendor contributed significantly to many other portions thereof.  The Owner
also acknowledges that, during the normal design, evolution and development
process, portions of the Specifications may appear in design and procurement
documents prepared by the Vendor in its normal course of business; provided,
                                                                   --------
however, that the Owner will have no liability for any third party infringement
- - - -------
claims arising from such Specifications prepared by the Vendor and the Vendor
will hold the Owner harmless from any such third party claims as provided in
subsection 14.2.

     27.19  Confidentiality.  (a)  All information, including without limitation
            ---------------
all oral and written information (including, but not limited to, determinations
or reports by arbitrators or the Third Party Engineer pursuant to the terms of
this Contract), disclosed to the other Party is deemed to be confidential,
restricted and proprietary to the disclosing Party (hereinafter
<PAGE>

                                                                              98

referred to as "Proprietary Information").  Each Party agrees to use the
Proprietary Information received from the other Party only for the purpose of
this Contract.  Except as specified in this Contract, no other rights, and
particularly licenses, to trademarks, inventions, copyrights, patents, or any
other intellectual property rights are implied or granted under this Contract or
by the conveying of Proprietary Information between the Parties.  Proprietary
Information supplied is not to be reproduced in any form except as required to
accomplish the intent of, and in accordance with the terms of, this Contract.
The receiving Party must provide the same care to avoid disclosure or
unauthorized use of Proprietary Information as it provides to protect its own
similar proprietary information but in no event will the receiving Party fail to
use reasonable care under the circumstances to avoid disclosure or unauthorized
use of Proprietary Information.  All Proprietary Information must be retained by
the receiving Party in a secure place with access limited to only such of the
receiving Party's employees, subcontractors or agents who need to know such
information for purposes of this Contract and to such third parties as the
disclosing Party has consented to by prior written approval.  All Proprietary
Information, unless otherwise specified in writing (i) remains the property of
the disclosing Party, (ii) must be used by the receiving Party only for the
purpose for which it was intended, and (iii) such Proprietary Information,
including all copies of such information, must be returned to the disclosing
Party or destroyed after the receiving Party's need for it has expired or upon
request of the disclosing Party, and, in any event, upon termination of this
Contract.  At the request of the disclosing Party, the receiving Party will
furnish a certificate of an officer of the receiving Party certifying that
Proprietary Information not returned to disclosing Party has been destroyed.
For the purposes hereof, Proprietary Information does not include information
which:

                         (i)   is published or is otherwise in the public domain
               through no fault of the receiving Party at the time of any
               claimed disclosure or unauthorized use by the receiving Party;

                    (ii)   prior to disclosure pursuant to this Contract is
               properly within the legitimate possession of the receiving Party
               as evidenced by reasonable documentation to the extent
               applicable;

                    (iii)    subsequent to disclosure pursuant to this Contract
               is lawfully received from a third party having rights in the
               information without restriction of the third party's right to
               disseminate the information and without notice of any restriction
               against its further disclosure;

                    (iv)   is independently developed by the receiving Party or
               is otherwise received through parties who have not had, either
               directly or indirectly, access to or knowledge of such
               Proprietary Information;

                    (v)   is transmitted to the receiving Party after the
               disclosing Party has received written notice from the receiving
               Party after termination or expiration of this Contract that it
               does not desire to receive further Proprietary Information;

                         (vi)   is obligated to be produced under order of a
               court of competent jurisdiction or other similar requirement of a
               Governmental Entity, so long as the Party required to disclose
               the information provides the other Party with prior notice of
               such order or requirement and its cooperation to the extent
               reasonable in preserving its confidentiality; or

                    (vii)    the disclosing Party agrees in writing is free of
               such restrictions.

     (b)  Because damages may be difficult to ascertain, the Parties agree,
without limiting any other rights and remedies specified herein, an injunction
may be sought against the Party who has breached or threatened to breach this
subsection 27.19.  Each Party represents and warrants that it has the right to
disclose all Proprietary Information which it has disclosed to the other Party
pursuant to this Contract, and each Party agrees to indemnify and hold harmless
the other from all claims by a third party related to the wrongful disclosure of
such third party's proprietary information.  Otherwise, neither Party makes any
representation or warranty, express or implied, with respect to any Proprietary
Information.

     27.20  Entirety of Contract; No Oral Change.  This Contract and the
            ------------------------------------
Exhibits and Schedules referenced herein constitute the entire contract between
the Parties with respect to the subject matter hereof, and supersede all
proposals, oral or written, all previous negotiations, and all other
communications between the Parties with respect to the subject matter hereof.
No modifications, alterations or waivers of any provisions herein contained will
be binding on the Parties hereto unless evidenced in writing signed by duly
authorized representatives of both Parties as set forth in subsection 27.1.  Any
representations by the Vendor in any RFP response and/or any documentation
otherwise provided to the Owner in connection with the Vendor's solicitation of
the business granted pursuant hereto prior to the execution hereof will also be
deemed to be incorporated into and otherwise made a part of this Contract;

provided that any such information will in no way be deemed to modify the
- - - -------- ----
Specifications unless otherwise specifically mutually agreed by the Parties.

     27.21  Successors and Assigns.  This Contract will bind and inure to the
            ----------------------
benefit of the Parties to this Contract, their successors and permitted assigns.

     27.22  Change of Control of the Vendor.  The Vendor will not consolidate
            -------------------------------
with or merge into any other Person or convey, transfer or lease all or
substantially all of its assets to any Person, nor will any Person or group (as
such term is defined in the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) own or acquire fifty percent (50%) of the value of the Vendor's
equity where such Person or group did not own as of the Effective Date in excess
of ten percent (10%) of such equity (any such Person or group will be referred
to as the "Vendor's Succeeding Entity"), unless:

                         (i)   the Vendor's Succeeding Entity will agree to
               assume the obligations of the Vendor under this Contract; and

                         (ii)   the Owner will have approved the transaction,
               based solely on (i) the creditworthiness of the Vendor's
               Succeeding Entity, (ii) whether the
<PAGE>

                                                                             100

               Vendor's Succeeding Entity is a competitor of the Owner and (iii)
               whether in the Owner's reasonable judgment the Vendor's
               Succeeding Entity will be able to fulfill the obligations for
               present and future orders under this Contract.

     Notwithstanding the foregoing paragraph, by provision of prior written
notice in accordance with this Contract, the Vendor will have the right, without
further consent of the Owner, to assign the Vendor's rights and delegate the
Vendor's obligations and liabilities under this Contract in whole (but not in
part), to any Person that is, or that was immediately prior to the assignment, a
current or former subsidiary, business unit, division or other affiliate of the
Vendor, provided that such entity is in fact the full successor to the Network
Systems Group (the "Successor") in connection with the transaction effecting
restructure of the Vendor and its affiliates announced on September 20, 1995
(the "AT&T Assignment").  The notice of the AT&T Assignment will state the
effective date of the AT&T Assignment.  Upon the effective date of the AT&T
Assignment, the Vendor will be released and discharged from all obligations and
liabilities under this Contract provided that the Successor will have assumed
                                -------- ----
all obligations and liabilities under this Contract.  The AT&T Assignment will
be complete and will not be altered by the termination of the affiliation
between the Vendor and the Successor.

     27.23  Change of Control of the Owner.  Except as otherwise permitted under
            ------------------------------
the documents relating to the financing of the build-out of the Nationwide
Network, the Owner will not consolidate with or merge into any other business
entity or convey, transfer or lease all or substantially all of its assets to
any Person, nor will any Person or group (as such term is defined in the
Exchange Act) own or acquire fifty percent (50%) of the value of the Owner's
limited partnership interests or general partnership interests where such Person
or group did not own as of the Effective Date in excess of ten percent (10%) of
either of such partnership interests (any such Person or group will be referred
to as the "Owner's Succeeding Entity"), unless:

     (a)  the Owner's Succeeding Entity will agree to assume the obligations of
the Owner under this Contract; and

     (b)  the Vendor will have approved the transaction, based solely on (i) the
creditworthiness of the Owner's Succeeding Entity and (ii) whether the Owner's
Succeeding Entity is a competitor of the Vendor.

     27.24  Relationship of the Parties.  Pursuant to subsection 27.9, nothing
            ---------------------------
in this Contract will be deemed to constitute either Party a partner, agent or
legal representative of the other Party, or to create any fiduciary relationship
between the Parties.  The Vendor is and will remain an independent contractor in
the performance of this Contract, maintaining complete control of its personnel,
workers, Subcontractors and operations required for performance of the Work.
This Contract will not be construed to create any relationship, contractual or
otherwise, between the Owner and any Subcontractor.
<PAGE>

                                                                             101

     27.25  Discretion.  Notwithstanding anything contained herein to the
            ----------
contrary, to the extent that various provisions of this Contract call for an
exercise of discretion in making decisions or granting approvals or consents,
the Parties will be required to exercise such discretion, decision or approvals
in accordance with accepted PCS industry practices and in good faith.

     27.26  Non-Recourse.  No past, present or future limited or general partner
            ------------
in or of the Owner, no parent or other affiliate of any company comprising the
Owner, and no officer, employee, servant, executive, director, agent or
authorized representative of any of them (each, an "Operative") will be liable
by virtue of the direct or indirect ownership interest of such Operative in the
Owner for payments due under this Contract or for the performance of any
obligation, or breach of any representation or warranty made by the Owner
hereunder.  The sole recourse of the Vendor for satisfaction of the obligations
of the Owner under this Contract will be against the Owner and the Owner's
assets and not against any Operative or any assets or property of any such
Operative.  In the event that a default occurs in connection with such
obligations, no action will be brought against any such Operative by virtue of
its direct or indirect ownership interest in the Owner.  The foregoing
provisions of this subsection 27.26 will not in any way limit or restrict any
right or remedy of the Vendor with respect to, and the Operatives will remain
fully liable for, any fraud perpetuated by such Operatives.

     27.27  Improvements, Inventions and Innovations.  All rights in any
            ----------------------------------------
improvements, inventions, and innovations made by the Owner will vest in the
Owner, and the Owner and its affiliates will have the right to exploit such
improvements, inventions, and innovations.  All rights in any improvements,
inventions and innovations made by the Vendor will vest in the Vendor, and the
Vendor and its affiliates will have the right to exploit such improvements,
inventions and innovations; provided, however, that subject to and in accordance
                            --------  -------
with subsection 11.9 the Owner and its affiliates may be granted certain rights
to improvements, inventions or innovations made in connection with the System
pursuant to subsection 11.9 by the Vendor (but not by any Subcontractor) in the
course and as a result of performing the Work and in which the Vendor owns or
possesses any proprietary interest (provided that the immediately preceding
                                    -------- ----
proviso of this last sentence of this subsection 27.27 is not subject to
subsection 23.2).

     27.28  Attachments and Incorporations.  All Schedules and Exhibits attached
            ------------------------------
hereto, are hereby incorporated by reference herein and made a part of this
Contract with the same force and effect as though set forth in their entirety
herein.

     27.29  Conflicts.  In the event of any conflict or inconsistency among the
            ---------
provisions of this Contract and the documents attached hereto and incorporated
herein, such conflict or inconsistency will be resolved by giving precedence to
this Contract and thereafter to the Exhibits, Schedules and Specifications.

     27.30  Counterparts.  This Contract may be executed by one or more of the
            ------------
Parties to this Contract on any number of separate counterparts, and all of said
counterparts taken together will be deemed to constitute one and the same
instrument.

        Attached are the Owner's System Area (or MTA) coverage definition maps.

Legend

        The highways shown in green are only those highways with an average
daily traffic count of greater than 10,000 vehicles.  The darker green
represents an average daily traffic count of greater than 50,000 vehicles.

        The census tracts of the System Areas were combined and ranked by demand
density in erlangs (wireless talk time traffic) per square mile for year 10,
based on busy hour (peak daily demand hour) minutes of use estimates.  Those
tracts which fall within the top 70% of the population total a national level
are displayed in red.  Those tracts which fall within the next 10% of the total
population (70 to 80% at the national level) are displayed in pink.

Initial System Coverage

        For contiguous Initial System coverage, the Contract's requirement is to
cover all of the red, pink and green areas within the blue "Arbitron Radio
Market" boundaries.  This represents 60% covered population at the national
level for the Initial System.

          Amendment No. 2, the Owner will carry out Functional  Acceptance Tests
          in  accordance  with the  provisions of Appendix K to Amendment No. 2,
          testing the  compliance  of the AS Software  with the AS  Statement of

          complete the AS  Functional  Acceptance  Tests no later than  fourteen
          (14) days after installation of such AS Software.

          after successful completion of the AS Functional Acceptance Test.

          (c) If the Owner fails to complete either the AS Functional Acceptance
          Tests or the Final  Acceptance  Test within the time periods set forth
          in subsections  9.7(a) and 9.7(b),  the AS Software shall be deemed to

          (d) The costs and expenses of the AS Acceptance Tests will be borne by
          the  Owner.  Upon  request  of the  Owner,  the  Vendor  will  provide
          reasonable  support to the Owner during the AS  Functional  Acceptance

          (e)  If the AS  Acceptance  Tests  show  that  any of the AS  Software
          complies  with the AS  Statement  of Work,  such AS  Software  will be
          accepted by the Owner by confirming the results in a written report.

          (f) If any AS Acceptance Test is not satisfied,  the Owner will (i) in
          writing,  notify the Vendor of such failure,  and (ii) the Vendor will
          promptly  correct  whatever  Defects or  Deficiencies  caused  such AS
          Acceptance Test not to be satisfied. After such correction, the Vendor
          must (i) repeat at its sole cost and expense the failed AS  Acceptance
          Tests and as many other AS Acceptance Tests as are necessary to ensure
          in the reasonable  opinion of the Owner that such  correction  made by
          the  Vendor  would not have  affected  the  outcome  of such  other AS
          Acceptance  Tests,  and (ii) in  writing,  notify the Owner as to what
          correction  was made  and  what AS  Acceptance  Tests  were  repeated.
          Nothing  stated  herein  to the  contrary  will in any way  limit  the
          Owner's right to  liquidated  damages  pursuant to subsection  15.8 or
          other  remedies  under this  Contract in the event the Vendor fails to
          deliver AS Products in accordance with the  requirements of Appendix G

          deliveries.

          (g) Minor Defects and  shortcomings  not affecting the operational use
          of any part of the AS Software shall not give rise to withholding  the
          acceptance  provided that the Vendor undertakes to remedy such Defects
          and  shortcomings  as soon as  reasonably  possible,  pursuant  to the
          procedures described in Appendix K to Amendment No. 2."

               Licensed Software.  The unmodified  Computer Programs provided by
               the Vendor,  including, but not limited to, the SCP/HLR Software,

               designates,  in writing, a specific modification or modifications
               to be restricted  from such  licensing  for a specific  period of
               time.

               accommodate  the Owner's need to preserve  compatibility  between
               the Owner's modifications and such Vendor-provided programs.

               Nothing  contained  in  this  subsection  12.5  to  the  contrary
               authorizes  the Owner to engage  any entity or person as an agent
               for hire to modify the Vendor's  SCP/HLR Software which entity or
               person (i) is  substantially  and directly engaged in competition

               the Vendor  regarding  the structure and contents of the Vendor's
               computer   programs   upon  terms   comparable   to  the  Owner's
               undertakings  to maintain  the  confidentiality  of the  Vendor's
               Proprietary Information."

               from, or modify AS Software  modules or menus,  if available from

               accordance with the AM/HLR  Specifications  and the HLR Statement
               of Work as an interim solution so that the Nationwide Network may
               operate in accordance with the Specifications;  provided that the
               Vendor will  continue to use its best  efforts,  at its sole cost
               and expense (but with all reasonable cooperation from the Owner),
               to replace  such interim  AM/HLR  solution  with a  comprehensive
               SCP/HLR system in accordance with the SCP/HLR  Specifications and
               the HLR Statement of Work.

               15.6 AM/HLR Redeployment.  After acceptance of the SCP/HLRs,  the
               Owner  will,  at the  Owner's  sole  discretion,  have the Vendor
               redeploy the AM/HLRs as Access Managers to other sites within the
               System  at the  Vendor's  sole cost and  expense  for any and all
               costs  associated  with  such  redeployment,  including  removal,
               transportation,  and delivery but not installation or the cost of
               such Access  Manager;  provided that if the Access Manager is not
               moved to another  location but redeployed in the same location in
               a separate function or for a separate MSC, the Owner will only be
               liable for the cost of the Access  Manager and the Vendor will be
               responsible  for all  other  costs.  All  payments,  if any,  for
               redeployed  AM/HLRs  will  be  made  by  the  Owner  pursuant  to
               subsection  6.3(a)-(d);  provided that in the event that any such
               redeployment  is to a  PCS  System  which  has  already  achieved
               Substantial Completion then the payment terms of subsection 6.3.1
               will apply.

               15.7 SCP/HLR Delay  Termination.  If after thirty (30) days after
               the  HLR   Completion   Dates  the  Vendor  is  still  unable  to
               satisfactorily  complete the Final Acceptance Tests applicable to
               the SCP/HLRs  and/or any of the SCP/HLR  Products to be delivered
               in accordance with the terms of this Contract (including, but not
               limited to, the SCP/HLR  Specifications)  the Owner will have the
               right (in  addition to any rights under  subsection  15.4 above),
               but not the  obligation,  to  terminate  the  Contract  only with
               respect to the SCP/HLR  Products  and will have the right to seek
               from  the  Vendor  reimbursement  for any of its  reasonable  and
               actual  increased  costs  associated  with  acquiring  reasonable
               replacement  SCP/HLR  Products from a third-party  supplier.  The
               remedies set forth in subsections 15.4, 15.5 and 15.7 will be the
               Owner's  sole and  exclusive  remedies  in the  event  the  Owner
               chooses to terminate the delivery of SCP/HLR Products pursuant to
               the terms of this subsection 15.7.

               15.8 AS  Software  Delay.  With  respect to the AS  Products  and
               Services,  in the event the Vendor  fails to deliver  any such AS
               Statement of Work compliant AS Products and/or AS Services within
               seven (7) days  (except as  provided  below,  the "AS Delay Grace
               Period")  of the  applicable  dates  for  delivery  set  forth in
               Appendix G to Amendment No. 2, the Vendor will (to the extent the
               Owner  will not have  cancelled  the  applicable  order  therefor
               pursuant  to the terms of the  Contract)  credit to the Owner (in
               the form of purchase  credits for any Vendor Products  including,
               but not limited to, AS Products) as  liquidated  damages for such
               late performance for each of the first  [_______________]  beyond
               such AS Delay Grace Period, an amount equal to [________________]
               per day (for such  [________________]  period) of the total price
               of such undelivered or unsatisfactory AS Products or AS Services;
               provided  that upon the timely AS Functional  Acceptance  (on the
               dates originally scheduled for such AS Functional  Acceptance) of
               any such AS  Products  and/or AS  Services,  any delay  penalties
               accrued  therefor shall be forgiven;  and provided further for AS
               Software  "release  0.1" (as  defined in Appendix G) the AS Delay
               Grace Period will be  [____________]  from the delivery dates set
               forth in Appendix G for the delivery of such AS Software  release
               0.1."

     14. Amendment to Subsection 17.1.  Subsection 17.1 is hereby amended to add
the following subsection 17.1.1 after subsection 17.1:

               "17.1.1 AS Products  Warranty.  Notwithstanding  anything  stated

               the Vendor warrants that, from the date of AS Final Acceptance of
               the  installation and Engineering  thereof,  the AS Products will
               materially  conform with and perform the  functions  set forth in
               the AS Statement of Work, to the extent  applicable,  and will be
               free from Defects and Deficiencies for a warranty period (each as

               Equipment,  one (1)  year.  In the  case of AS  Software,  the AS
               Product  Warranty Period  applicable to any such AS Software will
               be  automatically  extended  for a new  ninety  (90)  day  period
               commencing  on the  date  of  the  completion  of any  applicable
               Software   Upgrade   and/or   Software   Enhancement   upon,  and
               simultaneous   with,  any  Software   Upgrade   and/or   Software
               Enhancement  issued  pursuant  to the terms of Section 12. To the

               covered pursuant to Appendix G to Amendment No. 2 from the Vendor
               in  accordance  with  the  terms  of this  Contract,  any such AS
               Products so ordered by the Owner and  delivered  and installed by
               the Vendor or its  Subcontractors  will be  warranted to the same
               extent as set forth  above,  from the earlier of (i) the date the
               Owner puts such  additional AS Products into In Revenue  Service,
               (ii) the date of the Owner's  acceptance  of such  additional  AS
               Products  and (iii)  thirty (30) days after the Vendor  completes
               the installation of such additional AS Products."

                                   APPENDIX L

         Application Software Products Maintenance and Support Services

6.1      GENERAL

     The provisions of this Appendix L apply to the furnishing of maintenance AS
Services by the Vendor for AS Software furnished by the Vendor.  This Appendix L
in no way limits,  modifies or otherwise  amends the Vendor's  obligations as to
maintenance Services for other Products pursuant to the terms of the Contract.

6.2      DEFINITIONS

     For the  purposes of this  Appendix L, the  following  terms shall have the
meanings indicated below:

     (a) "AS  Severity  Level"  means  the  priority  status  of an AS  Software
condition  that is indicative  of the severity of the reported  condition as set
forth in the table below.

     (b) "Corrective  Maintenance" means maintenance performed or required to be
performed  by the Vendor upon  written or oral request of the Owner to correct a
Defect in the AS Software.

     (c) "Maintenance  Updates",  to be provided from time to time by the Vendor
but in any event, at least monthly, consist of at least the following:

               (i)  revised  object code as  appropriate  for AS Software in the
               same  machine-readable  storage  media  form as the  original  AS
               Software; and

               (ii) new or  modified AS Software  documentation  or  information
               regarding such documentation.

     (d)  "Problem  Resolution  Management"  means the  procedures  and  actions
performed or required to be performed by the Vendor upon written or oral request
of the Owner to act in an ombudsman-type capacity and investigate and manage the
resolution of a reported condition so that the Owner has a single interface that
is  engaged in  pursuing a problem  through  to its  resolution.  This  includes
Corrective  Maintenance in the case of a reported Defect in AS Software  covered
by the Contract.

     (e)  "Response  Time" means the maximum  period of time,  in hours,  within
which the Vendor will acknowledge the Owner's written or oral  notification of a
Defect,  make an initial  assignment of the  appropriate  AS Severity  Level and
initiate corrective action and escalation procedures.

6.3      SERVICE DESCRIPTION

     Maintenance  AS Services for AS Software  include,  but are not limited to,
fixed-term  Service and AS/T&M  Service.  Unless  otherwise  agreed by Vendor in
writing,  maintenance AS Service is only available for the then present  generic
and the then immediately preceding generic.

     (a) Fixed-term maintenance AS Service consists of procedures, as determined
by the Vendor for particular AS Software and for fixed  periods,  to keep the AS
Software  operating  consistent  with the AS Statement of Work. Such AS Services
include diagnostic  Service using on-site or remote techniques,  as appropriate,
to analyze a problem and prescribe  remedial  action,  and mandatory  escalation
procedures to provide successively higher levels of expertise.  Such AS Services
do not include  support for  administrative,  operational,  or keyboard  command
questions.  Fixed-term maintenance AS Services will be rendered primarily during
the Service hours reasonably requested by the Owners.

     (b) Each  order  for  fixed-term  maintenance  AS  Services  shall be for a
minimum of one (1) year and shall  commence on the date set forth in the Owner's
order  therefor.   The  Vendor  shall  give  written  notice  of  the  impending
termination  of an order at least  sixty  (60)  days  prior to the date for such
renewal,  at which time the Owner may consider renewal, in its sole and absolute
discretion.

     (c) AS/T&M Service  includes,  on a call-by-call  basis and on the basis of
the Vendor's AS Services  personnel  availability,  technical  assistance  using
on-site or remote techniques,  as appropriate,  to analyze a problem,  prescribe
remedial action and, if ordered, make necessary repairs to AS Products.

6.4      ELIGIBILITY FOR MAINTENANCE SERVICE

     AS Software  installed  by the Vendor is eligible for  maintenance  Service
without  initial  evaluation  by the Vendor  provided the Service  commences not
later than the end of the Warranty Period.

     In all  other  situations,  the AS  Software  shall  not  be  eligible  for
maintenance  Service  until  the  Vendor,  at its  option,  has made an  initial
evaluation  to  determine  whether  modifications  are  required  to make the AS
Software eligible.  If, in the Vendor's reasonable  judgment,  modifications are
required for this  purpose,  the Vendor will provide an estimate to the Owner of
the costs of making such  modifications.  The Owner will be invoiced at Vendor's
then standard  reasonable  rate for such  evaluation and any such  modifications
furnished by the Vendor and accepted by the Owner.

6.5      PERIODS OF AS MAINTENANCE SERVICE

     AS Maintenance Service will be provided twenty-four (24) hours a day, three
hundred  sixty-five (365) days a year, unless otherwise agreed by the Parties in
writing.

6.6      AS MAINTENANCE SERVICE EXCLUSIONS

     Unless  expressly  agreed by Vendor,  maintenance  Services  to be provided
under this Appendix L will not include:

     (a) Work  external to the AS Software,  whether or not on the AS Software's
Designated Processor;

     (b) Making AS Specification  changes or performing  Services connected with
relocation of the AS Software;

     (c) Such  Service  which is  impractical  for  Vendor to render  because of
changes  not  authorized  by  Vendor  in  the  Designated  Processor,   hardware
configuration or Vendor's AS Software; and

     (d)  Modification  or  replacement  of AS  Software,  repair of damage,  or
increase in Service time caused by:

               (i)  Failure  to  provide  a  reasonably   suitable   operational
               environment  with all  facilities  prescribed  by the  applicable
               manual including,  but not limited to, the failure to provide, or
               the failure of, reasonable electrical power, air conditioning, or
               humidity control;

               (ii) The use of the AS  Software  in a manner  not in  accordance
               with the AS Statement of Work (except as otherwise  authorized by
               the Vendor);

               (iii) Accident; disaster, which shall include, but not be limited
               to, fire,  flood,  water,  wind,  and lightning  (but only to the
               extent such AS Software should not have withstood such conditions
               pursuant to and in  accordance  with the AS  Statement  of Work);
               transportation not provided by or arranged by Vendor; neglect, or
               misuse by anyone other than Vendor,  its  employees,  agents,  or
               subcontractors;

               (iv)  Modifications,  maintenance,  or repairs performed by other
               than Vendor, its employees, agents, or subcontractors;

               (v) The  conversion  from  one  Vendor  AS  Software  release  to
               another,  or the failure of Owner to reasonably  apply previously
               applicable  modifications and corrections furnished by the Vendor
               (excluding any items in Appendix G); and

               (vi)  The  use of the  AS  Software  in  combination  with  other
               Software not furnished by Vendor,  except where such combinations
               are specified in Vendor's  Specifications  for the AS Software or
               are  approved  by Vendor in  writing;  provided  that any  Nortel
               Software (as defined in the Nortel  Agreement) shall be deemed to
               be  authorized  by the  Vendor for any such  combinations  to the
               extent such Nortel  Software needs to  interoperate  or otherwise
               integrate with the AS Software in order for the entire Nationwide
               Network to operate with the AS Software.

     At the request and acceptance of the Owner,  the Vendor will perform any of
the following  Services at the Vendor's  reasonable rates and terms in effect at
the time of such request.

6.7      MAINTENANCE OF RELOCATED AS SOFTWARE

     AS  Software  Serviced  under  the  Contract  which  is  moved  to  another
Designated  Processor  within the Territory  shall  continue to be covered under
this  Agreement  provided  that the Vendor has received  fifteen (15) days prior
written notice of such relocation and, if requested by Vendor,  the Parties have
renegotiated the objective response time selected by the Owner in the order. The
Vendor reserves the right to supervise the unloading of the AS Software from the
original  processor  and to inspect  and  reinstall  the AS  Software at the new
installation location; provided that in such event, the Vendor must exercise any
such  rights,  promptly  and in a  workmanlike  manner.  If the Owner  elects to
utilize the Vendor's services hereunder, the Owner shall be charged for all such
work performed by Vendor at the Vendor's then reasonable rates.

6.8      SCOPE OF AS SOFTWARE MAINTENANCE AS SERVICES

     (a) All Designated  Processors covered for maintenance AS Services shall be
listed in the order along with their physical  location and serial numbers.  The
Owner may add or delete any Designated Processor upon the Owner's written notice
to the Vendor. Unless otherwise agreed by the Vendor in writing,  maintenance AS

follow-up to the diagnostic support.

     (1) AS SOFTWARE DEFECTS

     (a) AS  Software - In  response to  maintenance  requests,  the Vendor will
provide  required  Corrective  Maintenance,  in accordance  with the AS Severity
Levels and Corrective Actions specified below for the AS Software in two ways:

                    (i) AS Emergency  Fixes - Vendor will provide  fixes such as
                    patches or changes to  operational  methods when it has been
                    determined  that the Defect is in the AS Severity Level 1 or
                    2 classification;

                    (ii) AS  Maintenance  Update - A  maintenance  update to the
                    standard  AS Software  release  will be issued on a periodic
                    basis to provide a fix to a group of conditions.

                    (iii)  AS  Related  Documentation  -  If  the  condition  is
                    isolated  to  the  AS  Related   Documentation  for  the  AS
                    Software,  the corrected  documentation will be given to the
                    Owner as part of the AS  Maintenance  Update or AS Emergency
                    Fix procedures.

     (2) OTHER PROBLEMS

     The Vendor will perform Problem Resolution Management for all components of
the total system, including AS Software, hardware and Firmware as follows:

     (a) Owner  Operational  Problems - If the condition is determined to be the
result of  unauthorized  use or misuse of the AS System by the Owner, it will be
referred back to the Owner by the Vendor. At the Owner's request the Vendor will
prepare a proposal for billable effort to correct such nonstandard use.

     (b) Data Base Problems - If the condition is determined to be the result of
corruption of the AS Software data base,  and such  corruption is not the direct
result of the AS Software,  the  condition  will be referred  back to Owner.  At
Owner's  request  and at  Vendor's  option,  Vendor may  prepare a proposal  for
billable effort to correct Owner's data base.

     (c)  Hardware/Firmware  Problems - When a  condition  has been  isolated to
hardware or Firmware  associated with the AS Software,  it will be referred back
to the Owner by Problem  Resolution  Management  personnel for disposition under
whatever maintenance arrangement the Owner may have.

     (d) Other Interfacing  Systems Problems - If the condition is determined to
be caused by mechanized  systems  other than the AS Software,  including but not
limited to those systems,  excluding any and all systems and/or products,  which
interface  with  the AS  Software,  it will be  referred  to  Owner  for  action
authorized and/or contemplated in Appendix G.

     (3) USER DOCUMENTATION

     Documentation will be provided for AS Maintenance Updates which will enable
the Owner to train its personnel in the operation of the AS Software as modified
by such releases.

     (4) NOTIFICATIONS OF CORRECTIONS

     The Vendor will issue bulletins periodically,  but not less than quarterly,
that describe  known Defects in the AS Software or known  interface  hardware or
Firmware Defects and the availability of corrections for them. Bulletins will be
provided to the Owner during the period in which Owner is receiving  maintenance
AS Services under the Contract for the applicable AS Software. The Owner will be
responsible for distribution of such bulletins within its own company;  provided
that the Vendor will use reasonable efforts to forward any such bulletins to the
appropriate personnel at the Owner then known to the Vendor.

     (5) CORRECTIVE MAINTENANCE RESPONSIBILITY

     The Owner  agrees to  install  the  corrections  or  replacements  provided
pursuant to the terms of this Contract as promptly as possible.  Owner's failure
to install  emergency fixes or patches or releases will cause the AS Software to
be considered nonstandard until all such fixes are installed.

     (6) [Intentionally Omitted]

     (7) PROBLEM DIAGNOSIS MATERIALS

     The Owner will use its reasonable  efforts to cooperate with the Vendor, in
the Vendor's  performance of its obligations  under and/or pursuant to the terms
of this Appendix L.

     (8) SEVERITY CONDITIONS AND PRIORITIZATION

     The Vendor shall  perform AS Problem  Resolution  Management  in accordance
with the AS System severity  condition after it has been assigned an AS Severity
Level by the Owner. The priority for problem condition  resolution will be based
on the AS Severity Level of outstanding reported conditions. AS Severity Level 1
conditions will receive top priority support.  In the event that notification of
a condition with a AS Severity Level 1 supplants and redirects  efforts expended
on a AS Severity Level 2 condition,  the Vendor will notify the Owner  reporting
such AS Severity  Level 2 condition that there will be a delay in correcting the
AS  Severity  Level 2  condition  and will  reschedule  efforts to correct  that
condition.

     (9) ESCALATION PROCEDURES

     The Vendor will observe the following escalation procedures:

     (a) AS Severity  Level 1 - In the event of a AS Severity  Level 1 condition
that is still  unresolved  four (4) hours after the  condition is reported,  the
Vendor  will  notify  the  Vendor's  supervisory  management  of the  unresolved
condition.  If the AS Severity Level 1 condition is still  unresolved  eight (8)
hours after the  condition  is  reported,  the next  higher  level of the Vendor
supervisory management will be notified of the unresolved condition.

     (b) AS Severity  Level 2 - In the event of a AS Severity  Level 2 condition
that is still unresolved twelve (12) hours after the condition is reported,  the
Vendor  will  notify  the  Vendor's  supervisory  management  of the  unresolved
condition.  If the AS Severity Level 2 condition is still unresolved twenty-four
(24) hours after the  condition  is  reported,  the next higher  level of Vendor
supervisory management will be notified of the unresolved condition.

     (10) HOT-LINE SERVICE

     The Vendor  will  provide an "800  Hot-Line"  telephone  Service for direct
telephone support to the Owner in an emergency  situation.  This Service will be
available  twenty-four  (24) hours a day,  seven (7) days a week for AS Severity
Levels 1 and 2 conditions only.  Prior to placing the call to the Hot-Line,  the
following steps shall have been completed by the Owner with assistance of Vendor
when necessary:

     (a)  Identification  of the  condition  and its  isolation  to a particular
component of the AS System believed to be the Vendor's responsibility.

     (b) Collection of sufficient  supporting  documentation from the system for
inclusion in the trouble report.

     (c) Determination that there are no outstanding program fixes which correct
the condition.

     Once the  solution is found,  the Vendor will supply it for testing and use
on the failed system.

     (11) NORMAL TROUBLE-REPORTING PROCEDURES

     Owner requirements and routines for reporting AS Severity Levels 2, 3 and 4
conditions are as follows:

     (a)  The  Owner  shall  prepare  a  trouble  report,  including  supporting
documentation and forward it to the Vendor.

     (b) The Owner may also  telephone  the Vendor's  Operation  Support  Center
(OSC) for answers to general operational  questions about the AS Software and/or
assistance in correcting Severity Level 3 and 4 conditions. The return call will
either provide the requested  information,  request additional  information,  or
report on the status of corrective action on the trouble report.

     (c) The calling Owner's personnel shall provide the following information:

                         Caller's   name,   location,   and  company   Call-back
                         telephone  number System name,  location  Generic issue
                         Processor  location,  type and serial  number Nature of
                         question or situation.

     (12) RESPONSE TIME

     The Vendor will provide a one (1) hour Response Time during the twenty-four
hour seven day a week coverage  period (the  "Standard  Coverage  Period").  The
response will involve the  establishment  of a mutually  agreed-upon AS Severity
Level for the  condition.  Appropriate  Corrective  Maintenance  and  escalation
procedures  will begin  during the Standard  Coverage  Period.  However,  at the
Owner's request,  the Vendor will immediately  initiate  Corrective  Maintenance
activities during other periods for a AS Severity Level 1 condition.

the  requirements  set  forth  in  clauses  (i) and (ii) of the  second  to last
sentence of  subsection  2.2(a) above.  In such event,  such a newly created PCS
Sub-System  will,  from such  point  forward,  be  treated  as a PCS  Sub-System
pursuant to the terms of this Contract.

             (c) Where the Owner wishes to purchase PCS Products or Services for
use and/or  application in a country  outside the United States but within North
America  including any  territory of the United States not otherwise  covered by
the  definition of the "United  States" as set forth  herein,  the Owner and the
Vendor will,  in good faith,  negotiate a separate  agreement  for such purchase
upon  substantially all of the same terms set forth in this Contract,  with only
such modifications as may reasonably be appropriate to reflect the international
nature of such transaction and to assure protection of the Vendor's intellectual
property.  The PCS Product and Software  prices and price discounts set forth in
this  Contract  will  prevail in any such  separate  agreement,  subject only to
reasonable  pricing  adjustments  which  will be in no event ten  percent  (10%)
higher than the prices set forth in or determined pursuant to this Contract plus
foreign import duties and taxes. Any such agreement may, at the Vendor's option,
be entered into by any of the  subsidiaries or other affiliates of the Vendor as
listed on Schedule 13.

             2.2.1 AS Products and AS Services  Additional  Coverage.  Where the
Owner wishes to purchase AS Products or AS Services  for use and/or  application
in a country  outside the United States but within North  America  including any
territory of the United  States not otherwise  covered by the  definition of the
"United  States" as set forth  herein,  the Owner and the Vendor  will,  in good
faith,  negotiate a separate  agreement for such purchase upon substantially all
of the same terms set forth in this Contract,  with only such  modifications  as
may  reasonably  be  appropriate  to reflect  the  international  nature of such
transaction  and to assure  protection  of the  Vendor's  intellectual  property
applicable to such AS Products and AS Services.

             2.3  Handsets.  (a) The  Vendor  must  supply  the  Owner  with two
thousand (2,000)  subscriber  handsets at the prices set forth on Schedule 2 and
substantially  meeting  the  applicable  criteria  set forth in Exhibit H within
sixty (60) days prior to the Substantial Completion of the Initial PCS System in
accordance  with Exhibit B3;  provided  that the criteria set forth in Exhibit H

of this Contract,  Exhibit B3 and  substantially in accordance with Exhibit H to
the extent  applicable;  provided however,  with the consent of the Owner, which
consent will not be unreasonably withheld, such handsets will not be required to
be in  substantial  compliance  with the criteria set forth in Exhibit H if they
will  otherwise be sufficient to test and  accurately  demonstrate  that the PCS
System  meets the  Specifications.  The one  hundred  (100) for each PCS  System
handsets  required to be  delivered  by the Vendor  pursuant to the  immediately
preceding  sentence will be delivered to the Owner on or before  Milestone 7 (as
set forth in  Exhibit  A1) for the first PCS  Sub-System  completed  in such PCS
System.

             (c) Notwithstanding any other provision of this Contract, including
Section 17, the Vendor does not warrant the handsets provided hereunder,  but to
the extent that the Vendor is authorized to do so by the terms of any applicable
agreement or agreements with such third party suppliers,  the Vendor will assign
or otherwise transfer any warranty received from its supplier(s) of the handsets
to the  Owner at no  additional  cost to the  Owner.  For the  purposes  of this
Contract  a  supplier   of   handsets  to  the  Vendor  will  not  be  deemed  a
Subcontractor.

             2.4  Initial  PCS  System.  Pursuant to Exhibit B3, the Vendor must
achieve Substantial  Completion of the Initial PCS System in accordance with the
requirements  of  Exhibit B3 prior to, and as a  condition  of, the  Substantial

             2.6 RF Engineering;  Site Acquisition and MSC Installation.  (a) In
accordance with Milestone 2 as set forth on Exhibit A1, the Vendor has delivered
to the Owner the  Preliminary  RF Design for each of the System Areas and System
Sub-Areas in accordance with the  requirements and criteria set forth in Exhibit
B1 and Schedule 1. The Vendor has provided the Owner with the applicable  search
rings for each PCS Sub-System  based upon the  Preliminary RF Design.  The Owner
and the Vendor agree to cooperate with each other to complete the RF Engineering
and the Site  Acquisition.  The Owner must notify the Vendor of desired coverage
areas, RF Engineering  parameters or other information or restrictions the Owner
wishes to be  included  in the  Final RF  Engineering  Plan for each PCS  System
and/or PCS Sub-System.  In accordance with Exhibit B1, the Vendor will do the RF
Engineering in each of the PCS Systems and/or PCS  Sub-Systems and in connection
therewith will use the parameters,  information and restrictions supplied by the
Owner. As part of the RF Engineering,  the Vendor will establish  "search rings"
in each of the PCS Systems  and/or PCS  Sub-Systems  that will specify  areas in
which the Owner may proceed with Site Acquisition.

             (b) In accordance with Exhibit B1 the Vendor, at its request,  must
be kept  informed of the progress made on ongoing Site  Acquisition  within each
System Area and System Sub-Area. As the Site Acquisition progresses,  the Vendor
agrees to regularly alter the RF Engineering plan to determine a new search ring
or rings to take into  account any  changes or  modifications  requested  by the
Owner or  otherwise  requested  by the Owner  due to the  Owner's  inability  to
acquire  sufficient rights to a location which could constitute a System Element
Location  in a  timely  or  economic  manner.  When  making  changes  to  the RF
Engineering plan the Vendor must take into account the Site Acquisition  already
completed by the Owner.

             (c)  Milestone  5 (as set forth in Exhibit  A1) will be achieved in
each PCS System and PCS Sub-System in accordance  with this  subsection  2.6(c);
provided that for each PCS System and PCS Sub-System the  appropriate  MSCs have
been  installed by the Vendor in the Owner's  relevant  Switch Sites within each
such PCS System and PCS Sub-System in accordance with  subsection  2.6(d) below.
In  accordance  with the  Project  Milestones  set forth on  Exhibit  A1 and the
requirements  and criteria set forth in Exhibit B1,  within five (5) days of the
Owner achieving Site Acquisition  Substantial  Completion within any System Area
or System Sub-Area (the "Final RF Review Period"), the Owner and the Vendor will
use their best efforts to agree on a final System  Element  Location  count (the
"Final Site Count") and a final RF  Engineering  plan (the "Final RF Engineering
Plan") for such System Area or System  Sub-Area,  as the case may be, upon which
the PCS System for such System Area and/or System Sub-Area,  as the case may be,
will be built by the  Vendor.  Failure  of the  Owner  and the  Vendor  to reach
satisfactory  agreement on a Final Site Count and/or a Final RF Engineering Plan
for any given System Area or System  Sub-Area  within the Final RF Review Period
will  automatically  result in the referral of any such disagreement to the most
senior RF  engineers  of both the  Owner and the  Vendor  for their  review  and
resolution  within  five (5) days  after  the end of any  such  Final RF  Review
Period. If the senior RF engineers fail to resolve any such disagreement  within
the extended five (5) day resolution period, the disagreement will automatically
be referred for resolution in accordance with subsection  23.1. It is understood
by the  Parties  that  during  the  period  of any  such  disagreement  and  the
resolution thereof in accordance with the Contract,  the Work on such PCS System
and/or  PCS  Sub-System,  to the  extent  possible,  will be  ongoing  and  that
Substantial  Completion on such PCS System and/or PCS  Sub-System  shall require
agreement  by the  Parties on a Final RF  Engineering  Plan  and/or a Final Site
Count for such PCS System and/or System Area and/or PCS Sub-System.

             (d) The Vendor will  install each of the MSCs in each of the Switch
Sites  within sixty (60) days of the Switch Site Ready Date;  provided  that (i)
the Owner will have provided the Vendor with the MSC  configuration  engineering
information  at least one  hundred  (100) days prior to the Switch  Site  Notice
Date,  for each such MSC, such that the Vendor may actually  perform the Owner's
MSC configuration engineering (other than the Switch Site layout configuration),
(ii) the Owner will have  provided  the Vendor with the  applicable  Switch Site
description (in appropriate detail) at least sixty (60) days prior to the Switch
Site  Notice  Date and (iii) as of such  Switch  Site Ready Date the  applicable
Switch  Site will have been made ready by the Owner such that the  relevant  MSC
can in fact be installed by the Vendor.  For the purposes hereof (i) the "Switch
Site Ready Date" means the date  specified by the Owner as the date on which the
Switch Site will in fact be ready for MSC  installation  as  communicated to the
Vendor by the Owner in the Owner's  Switch  Site Notice to the Vendor,  (ii) the
"Switch Site Notice Date" will mean,  as to any Switch Site Notice,  the date on
which such notice was delivered to the Vendor by the Owner and (iii) the "Switch
Site  Notice"  will  mean the  notice  provided  to the  Vendor  by the Owner in
sufficient  detail to describe the Switch Site so that the Vendor may reasonably
engineer the layout of the MSC configuration  specifically for such Switch Site.
Nothing contained herein will in any way limit the Vendor's  obligation pursuant
to the terms of this Contract to do the MSC  engineering  and the RF Engineering
in  accordance  with the terms of this  Contract.  Pursuant  to this  subsection
2.6(d) in no event will the Owner provide the Vendor the Switch Site Notice more
than sixty (60) days later than the date the Owner delivers the Vendor the Build
Notice pursuant to subsection 2.7(a).

             2.7 Facilities  Preparation Services and Installation.  (a) For any
PCS System and/or PCS Sub-System  within the Initial System prior to Milestone 5
(as set forth on Exhibit A1) for such PCS System or PCS Sub-System,  as the case
may be, the Owner (i) may, in its discretion,  provide notice to the Vendor when
it has achieved Site Acquisition of at least fifty (50) System Element Locations
in any given PCS System  and/or PCS  Sub-System,  as the case may be, or (ii) in
any event,  (if the Owner hasn't already  provided notice pursuant to clause (i)
above)  will  provide  such  notice  to the  Vendor  when it has  achieved  Site
Acquisition of at least thirty percent (30%) of the System Element  Locations in
such PCS Sub-System,  as the case may be (in either event,  the "Build Notice").
The Build Notice calculation will be based upon the Owner's reasonable  estimate
of System  Element  Locations  within or in connection  with the  Preliminary RF
Design  applicable to the PCS System  and/or PCS  Sub-System in which such Build
Notice is issued to the  Vendor.  The Build  Notice  for each PCS  System or PCS
Sub-System  will also include the Owner's best forecast  based upon  information
available  at such time (the "M5  Forecast")  of when it  expects  to be able to
declare Site Acquisition  Substantial  Completion  within such PCS System or PCS
Sub-System.  The Owner  understands  that the  Vendor  will not be  required  to
commence Facilities  Preparation  Services and/or Installation in any PCS System
or PCS Sub-System  until and unless the Vendor has received the applicable Build
Notice pursuant to and in accordance with this subsection 2.7.

             (b) In accordance with the Project Milestones  specified in Exhibit
A and the  requirements  and criteria of Exhibit B2, for each System Area and/or
System Sub-Area the Vendor must complete the Facilities Preparation Services for
all System Element  Locations  within such PCS System and/or PCS Sub-System,  as
applicable,  in accordance with the construction criteria set forth in Exhibit E
and the  performance  criteria  set forth in Exhibit F no later than ninety (90)
days  from the  Owner/Vendor  agreement  on a Final  Site  Count  and a Final RF
Engineering Plan for such System Area and/or System Sub-Area; provided that upon
the prior written  request of the Vendor,  the Owner may consent  (which consent
will not be  unreasonably  withheld)  to  postpone  Milestone 6 (as set forth in
Exhibit A1) with  respect to any PCS System  and/or PCS  Sub-System  by not more
than an additional sixty (60) days in the event that more than ten percent (10%)
of the  System  Element  Locations  in such PCS  System  and/or  PCS  Sub-System
estimated  as of the date of the Build  Notice  for such PCS  System  and/or PCS
Sub-System  have not been fully acquired by the Owner  immediately  prior to the
date on which Milestone 5 (as set forth in Exhibit A1) otherwise  occurs in such
PCS System and/or PCS Sub-System.  Pursuant to the Project Milestones the Vendor
must  complete  Installation  of the  Products  for any given PCS System  within
thirty-two  and one  half  (32-1/2)  days of its  completion  of the  Facilities
Preparation Services in accordance with Milestone 6 (as set forth on Exhibit A1)
for such PCS System  pursuant  to the  requirements  and  criteria  set forth in
Exhibit D and Exhibit F.

             2.8 Site  Acquisition  Modifications.  In the event  that the Owner
determines  that  it  is  unlikely  to  achieve  Site  Acquisition   Substantial
Completion   for  any  PCS  System  and/or  PCS   Sub-System  in  a  timely  and
cost-effective  manner, the Vendor will modify certain performance  criteria set
forth in Exhibit F with respect to such PCS System and/or PCS  Sub-System in the
manner and to the degree that the Owner  reasonably  specifies in writing to the
Vendor  in  accordance  with the  terms of  Exhibit  B3.  In the event the Owner
notifies the Vendor of a  modification  to the System  performance  criteria for
such PCS System  and/or PCS  Sub-System  pursuant to this  subsection  2.8, such
modified  criteria,  including any such lower number of System Element Locations
that the Owner, in its sole discretion, deems at such time to be satisfactory so
as to constitute Site  Acquisition  Substantial  Completion,  will be deemed the
performance  criteria and the System Element  Location count  applicable to such
PCS System for the  purposes of Milestone 5 (as set forth on Exhibit A1) and all
other  remaining  Project  Milestones  for such PCS System and/or PCS Sub-System
thereafter.

             2.9 Design/System  Architecture and Engineering;  Interoperability.
(a) The Vendor must provide all Engineering  and design  services  necessary for
the completion of the Work and the System in conformity with the  Specifications
and the CDMA  standards,  including,  but not  limited to, the  Engineering  and
design necessary to describe and detail the System and the specified PCS Systems
and/or PCS Sub-Systems.

             (b) Pursuant to and in accordance with the terms of Exhibits B3 and
G,  BTS/BSC-MSC  Interoperability  must be demonstrated on or before December 1,
1996  (provided  that such date will change to reflect the actual  delay  beyond
December  31,  1995 in the  finalization  of  "Attachment  A" to be  attached to
Exhibit  G);  provided  that in any event the  requirements  of this  subsection
2.9(b) are a condition to the Vendor's  Substantial  Completion  of the last PCS
System  within the Initial  System and  Substantial  Completion of such last PCS
System will not be deemed to have been  achieved by the Vendor  unless and until
such  Interoperability  will  have  been  demonstrated  in  accordance  with the
criteria  set  forth in  Exhibit  G;  provided  further  that any  delay in such
Interoperability  which is not due  substantially to the fault of the Vendor, in
the reasonable  opinion of the Owner,  will not be a delay pursuant to the terms
of this subsection 2.9(b).

             (c) It is  expressly  understood  and agreed by the Vendor that the
Substantial Completion of any PCS System and/or PCS Sub-System will (in addition
to all other  requirements  of PCS System  (and/or PCS  Sub-System)  Substantial
Completion set forth in this Contract) be subject to, and conditioned upon, such
PCS  System  and/or  PCS  Sub-System,  as the  case may be,  pursuant  to and in
accordance with the  Specifications,  operating and interoperating with any then
operating  and/or  in  service  Owner  and/or  Affiliate  PCS  Systems  and  PCS
Sub-Systems  (and/or PCS  systems  and/or PCS  sub-systems,  as the case may be)
which  comply  with  the  relevant  ANSI  standards  and  other   specifications
identified in Exhibit D.

             (d) The Vendor  will use its best  efforts  to work with  Nortel in

             (f)  Notwithstanding  anything  to the  contrary  in the  Contract,
Substantial Completion of any PCS System or PCS Sub-System,  as the case may be,
within the Initial System,  and the testing  required  therefor,  will expressly
require and be conditioned  upon the successful  integration and  interoperation
(in accordance with the AM/HLR Specifications), of the other Products within any
such PCS System and/or PCS Sub-System with the then existing  AM/HLRs within the
Nationwide Network.

             (g) For each applicable  Actiview Software release,  the Acceptance
Procedures  for such  release are to be mutually  agreed  between the Parties no
later than one (1) week prior to the delivery by the Vendor of any such release.
Failure of the Parties to so  mutually  agree at such time will in no way modify
the Vendor's  obligation to timely  deliver any such Actiview  Software  release
pursuant to and in accordance with the Actiview Statement of Work.

             2.10  Certification.  The Vendor must coordinate its performance of
the Services described in subsection 2.9 with the Engineering and design efforts
(including,   without  limitation,  any  and  all  RF  Engineering  and/or  Site

notice of its intent to test any such  Vendor  Development  and upon the Owner's
written  request the Vendor will allow the Owner to  participate in such testing
upon terms and in a testing environment  reasonably acceptable to the Parties at
such time. The Owner will make its Test-bed Laboratory and/or certain of its PCS
Systems and/or PCS Sub-Systems (following Final Acceptance thereof) available to
the Vendor for any such testing in which the Owner has the right,  and will have
notified the Vendor of its desire,  to  participate  in pursuant to the terms of
this  subsection  2.11.2.  Where the Vendor and the Owner have  agreed  that the
Owner's Test-bed  Laboratory or PCS System and/or PCS Sub-System will be used as
a test bed for Vendor  Developments,  the Owner will not unreasonably refuse the
Vendor's requests for other Customers to observe the tests or to release results
of the  tests  to  other  Customers;  provided  that  the  Owner  will  have had
reasonable  prior  notice  that the Vendor  would  like to have other  Customers
observe  such  testing and that the Vendor will  remain  liable in all  respects
pursuant  to the  terms  of this  Contract  for the  protection  of  Proprietary
Information in connection with any such testing.  The length of the prior notice
period  described  above may be shortened to under thirty (30) days if necessary
and  appropriate  under the  circumstances,  but in no event will any such prior
notice period be less than ten (10) days.

             2.12  Safety.  To the extent the Vendor is in control of any System
Element Location,  or other site within the System or any System Area during the
term  of this  Contract  (a  "Vendor-Controlled  Location")  including,  but not
limited  to,  during the  build-out  of the Initial  System,  the Vendor will be
solely  responsible  for  initiating,  maintaining,  and  supervising all safety
precautions  and  programs  in  connection   with  all  such   Vendor-Controlled
Locations. The Vendor must materially comply with Applicable Laws and Applicable
Permits  and the  Specifications  bearing on safety of persons  or  property  or
protection  against  injury,  damages or loss. The Vendor must provide a written
report  to the Owner  describing  fully all  incidents  affecting  safety on any
Vendor-Controlled  Location  and must also  furnish  to the Owner  copies of all
MSHA, OSHA and workers' compensation reports. The Vendor acknowledges and agrees
that until  Bolt-down  of all of the PCS  Products  to be provided by the Vendor
pursuant to the terms of this  Contract  on any given  System  Element  Location
(other than the Switch  Site or the  Test-bed  Laboratory)  within any given PCS
System  and/or PCS  Sub-System  is  achieved  the Vendor will be deemed to be in
control  of  all  Products,   tools,  designs,   buildings,   structures  and/or
Engineering (other than those Products,  tools, designs,  buildings,  structures
and/or  Engineering  specific to and  necessary  for Site  Acquisition,  Network
Interconnection  and/or  Microwave  Relocation)  at, in or upon any such  System
Element Location within such PCS System and/or PCS Sub-System;  provided that in
any event for each such System Element Location the Vendor will always be deemed
to  be  in  control  of  such  System  Element  Location  until  the  Facilities
Preparation  Services for such System  Element  Location have been  completed in
accordance with Exhibit B2.

             2.13   Emergencies.   In  the   event   of  any   emergency   at  a
Vendor-Controlled  Location  endangering life or property,  the Vendor must take
such action as may be  reasonable  and  necessary to prevent,  avoid or mitigate
injury, damage or loss and will, as soon as possible, report any such incidents,
including  the  Vendor's  response  thereto,  to  the  Owner.  Whenever,  in the
reasonable  opinion  of the Owner,  the  Vendor  has  failed to take  sufficient
precautions  for the  safety of the public or the  protection  of the Work or of
structures  or  property  on or  adjacent  to  any  Vendor-Controlled  Location,
creating,  in the  reasonable  opinion  of the  Owner,  an  emergency  requiring
immediate action,  then the Owner, after having given reasonable prior notice to
the Vendor, may cause such sufficient  precautions to be taken or itself provide
such  protection.  The taking or provision of any such precautions or protection
by the Owner or its  agents or  representatives  will be for the  account of the
Vendor and the Vendor must reimburse the Owner for the cost thereof.

             2.14  Right  of  Inspection.   The  Owner,  the  parties  providing
financing in connection  with the build-out of the Nationwide  Network and their
duly appointed representatives, including Inspectors (collectively "Reviewers"),
will at all  reasonable  times have access to the various sites where the Vendor
or its  Subcontractors  are prosecuting the  Engineering,  design,  procurement,
testing or manufacture of the Work;  provided that this subsection 2.14 will not
be  presumed  to give access to the  Vendor's  or its  Subcontractors'  sites to
direct  competitors  of the Vendor  provided  that such sites are not  otherwise
Owner sites. For these purposes,  reasonable  access will be given during normal
business hours to the Vendor's and its Subcontractors' plants, premises, storage
and deposit areas, facilities and offices, sources of materials, Equipment being
assembled, already assembled or in operation, Equipment being performance tested
or  tested  to the  Vendor's  specifications  and to any  other  places or areas

Notwithstanding  anything herein to the contrary, any Reviewer's right of access
to the Vendor's and/or the Subcontractors' plants, premises, storage and deposit
areas, facilities and offices, sources of materials,  Equipment being assembled,
already assembled or in operation,  Equipment being performance tested or tested
to the Vendor's  specifications and to any other places or areas occupied by the
Vendor or its  Subcontractors in connection with the Work will be subject to the
reasonable confidentiality, safety and security requirements of same and further
subject to such Reviewers'  non-interference  with the Work and other work being
performed thereon. The Vendor must provide reasonable temporary office space (in
the  Vendor's  facilities  where such space is  available)  and services for the
Reviewers to the extent necessary.

             2.15 Transportation.  The Vendor must provide for the transport and
delivery of all the  Products to be  delivered  pursuant  to, and in  accordance
with,  the terms of this  Contract.  The costs for such  transportation  will be
borne by the Vendor as part of the Contract Price;  provided that the Owner will
reimburse the Vendor for any costs incurred by the Vendor for any  Extraordinary
Transportation  in such cases where the Vendor,  subject to prior  notice to the
Owner, found it actually necessary to utilize such Extraordinary Transportation;
provided,  further that any amounts due to the Vendor from the Owner pursuant to
the first  proviso  of this  subsection  2.15 will be  reduced  by the amount of
non-extraordinary   transportation   costs  which   otherwise  would  have  been
applicable to the transport of such Products.

             2.16 Security. Subject to subsection 2.12, during the course of the
Work,  the Vendor will  perform the  security  services  necessary to ensure the
safety and security of the System Element  Locations,  the Products and/or other
materials or designs relevant to the Work.

             2.17 Materials and Equipment.  Except for materials or Equipment to

materials or Equipment are  specified or described in this  Contract  (including
the  Specifications)  by using the name of a  proprietary  item or the name of a
particular  supplier,  the naming of the item is intended to establish the type,
function  and quality  required,  and  substitute  materials  or  Equipment  may
nonetheless be used, provided that such materials or Equipment are equivalent or
equal to that named. If the Vendor wishes to furnish or use a substitute item of
material  or  Equipment,  the  Vendor  must  first  certify  that  the  proposed
substitute  will perform at least as well the  functions and achieve the results
called for by this Contract, will be substantially similar or of equal substance
to that  specified and be suited for the same use as that  specified.  The Owner
may require the Vendor to furnish,  at the  Vendor's  expense,  additional  data
about the  proposed  substitute  as required to evaluate the  substitution.  For
Major  Portions  of the Work,  or  materials  or  Equipment  listed on part B of
Schedule 7, the Vendor must first receive  prior  written  approval of the Owner
for any  substitution.  The Owner will be allowed a reasonable time within which
to evaluate  each  proposed  substitute.  Notwithstanding  the  foregoing,  with
respect to PCS Products,  prior to the shipment of such PCS Products pursuant to
the terms of this  Contract,  the  Vendor may at any time  without  notice to or
consent of the Owner make changes in a Vendor PCS Product furnished  pursuant to
this  Contract,  or modify the drawings and  published  specifications  relating
thereto,  or  substitute  Products  of  similar or later  design to fulfill  its
obligations  under this Contract or otherwise  fill an order,  provided that the
changes,  modifications  or  substitutions  will in no way  affect or  otherwise
impact upon the form, fit, or function of an ordered Product  pursuant to and in
accordance  with  the  applicable  Specifications.   With  respect  to  changes,
modifications  and  substitutions  which do in fact  affect  the form,  fit,  or
function  of  an  ordered  Product  pursuant  to  and  in  accordance  with  the
Specifications, the Vendor must notify the Owner in writing at least thirty (30)
days  prior  to the  effective  dates  of any  such  changes,  modifications  or
substitutions.  In the event that any such change,  modification or substitution
is not desired by the Owner, the Owner will notify the Vendor within thirty (30)
days from the date of notice and the Vendor will not  furnish  any such  changed
Products  to the  Owner on any  orders  in  process  at the time the Owner is so
notified;  provided  that nothing  contained  herein will  otherwise  modify the
Vendor's obligations under the terms of this Contract.

the Vendor with respect to any PCS System and/or PCS  Sub-System an amount equal
to the Owner's  reasonably  estimated  cost of any utilized spare parts for such
PCS System and/or PCS  Sub-System,  as the case may be, not so replaced prior to
Final  Acceptance;  provided that such withheld funds will be released upon such
satisfactory replacement of such spare parts by the Vendor.

             (c) To the extent  that  System PCS spare parts need to be acquired
from third party suppliers, the Vendor will use its reasonable efforts to obtain
from  suppliers a supply of System spare parts at no additional  cost as part of
the original Product package. To the extent that the Vendor is able to so obtain
such System spare parts at no  additional  cost as part of the original  Product
package,  it will provide such System spare parts to the Owner without cost (and
without any charge for the procurement of such spare parts by the Vendor).

             2.26 System Support Services. The Vendor will provide the specified
support services for the operation, maintenance and repair of the System and all
Products  to the  extent  set  forth  herein  below  and at the  Annual  Release
Maintenance Fees.

                      2.26.1  Vendor Assistance.  (a)  Upon receipt of a request
for technical assistance from the Owner, the nature of the problem will be iden-
tified by the Owner, and a priority assigned by the Owner (upon  discussion
with the Vendor  which in no event will require the  agreement  and/or  consent
of the Vendor) as either an emergency or non-emergency  condition and resolution
thereof will be expedited in accordance with the severity levels set forth be-
low.

             (b)  Following  attempted   corrective  actions  by  the  Owner  in
accordance with applicable  Maintenance and Instruction  Manuals provided by the
Vendor,  when the  Vendor is  notified  by the Owner  that the  System,  any PCS
System,  any PCS  Sub-System  or any part thereof fails to operate in accordance
with the Specifications, the Vendor will promptly commence and diligently pursue
all  reasonable  efforts to identify the Defect or Deficiency  and, in the event
the Vendor has responsibility therefor, to correct such Defect or Deficiency.

             (c) The Vendor's  correction of such Defects or Deficiencies in the
System,  any PCS System, any PCS Sub-System,  or any part thereof,  may take the
form of new software  codes,  new or  supplementary  operating  instructions  or
procedures,  modifications of the software codes in the Owner's  possession,  or
any other  commonly  used  method  for  correcting  Defects or  Deficiencies  in
Software, as the Owner and the Vendor deem appropriate.

             (d)  When  appropriate,   the  Vendor  will  provide  non-emergency
technical support to the Owner via telephone, facsimile transmission,  modem, or
other means acceptable to the Owner during the Owner's normal business hours.

             (e) The Vendor will provide emergency  technical  assistance to the
Owner via an ETA  telephone  number  designated  to the Owner in  advance by the
Vendor,  twenty-four (24) hours per day, three hundred sixty-five (365) days per
year.

             (f) The Vendor will  provide  remote  intervention  and  assistance
capability to the Owner for remotely accessing  operating System Elements.  Upon
mutual agreement  between the Parties,  the Vendor may remotely access operating
System Elements for the purpose of ETA.

                      2.26.2  Trouble Reports.  From time to time, failures in,
or degradation of, Products may cause services provided by the System to be ad-
versely affected.  It is necessary that  immediate  assistance  be  provided  by
the  Vendor  to allow the Owner to restore the affected  service.  Critical ser-
vice outages that cannot be resolved by the Owner's field technicians or techni-
cal support engineers using procedures described in the Operating  Manuals,
Maintenance  and  Instruction  Manuals and Training  will be  transmitted  to
the Vendor as a Trouble  Report  ("TR").  The Vendor  will  assign an  identi-
fying  number to each TR to aid in  tracking  its resolution.  TRs will be imme-
diately  addressed by the Vendor through  Emergency Technical  Assistance under
guidelines set forth in subsection  2.26.3.  TRs may not be considered  conclud-
ed until the solution is concurred upon by an employee of the Owner within the
Owner's  operations  control  center  ("OCC").  The root cause of problems  re-
sulting in TRs may be Defects or Deficiencies which must be corrected  through
Product  or  procedure  changes.  Problems  with the  System requiring  such
changes  will be  referred  to the Vendor for action  through a Customer  Ser-
vice  Request  ("CSR").  The Vendor is  authorized  by the Owner to install and
integrate, at the Vendor's expense, any Software Upgrade or Software Enhancement
pursuant to mutual  agreements  reached  between the Vendor and the Owner.

                      2.26.3  Emergency Technical Assistance.  (a)  When a prob-
lem is encountered that adversely affects  service or  performance  with respect
to the  Products,  any PCS System and/or PCS Sub-System,  the System or any part
thereof, in each case provided by the Vendor,  an Owner  maintenance  techni-
cian will attempt to repair or replace any malfunctioning Product adversely
affecting such service or performance using the procedures  recommended in the
Maintenance  and  Instruction  Manuals or the Operating Manuals. If unsuccess-
ful, a technical representative of the Owner will consult the Vendor's  desig-
nated ETA group at the telephone  number  provided by the Vendor in subsection
2.26.3(c) below.  Following receipt of notification by the ETA group, the ETA
group will utilize all available  technical resources and will ensure  that a
qualified  technical  engineer  is  communicating  with the Owner's  personnel
regarding the problem on average within fifteen (15) minutes of any such  noti-
fication;  provided that no single  response will exceed thirty (30)  minutes.
If necessary  and  appropriate  the Owner's  technician  will be dispatched to
assist in the normal change-out of replaceable hardware units.


                      (b)  A problem adversely affecting service that has a
severity level defined below either as an "E1 Emergency  Condition"  or an
"E2 Emergency  Condition" is to be addressed under  the ETA  procedures  set
forth  below in this  subsection  2.26.3  and in subsection 2.26.4.

                 (i)  An E1 Emergency  Condition (this roughly  corresponds to a
                      Critical Condition in the Vendor's ISO 9001 documentation)
                      means  a  problem  resulting  from  any one or more of the
                      following events:

- -        Any system-initiated event or unplanned manual restart (warm, cold,
                  reload or image) which causes a system loss of all call
                  processing capability for more than thirty (30) seconds.
                  Manual restarts with twenty-four (24) hour notice would
                  be planned.
- -        Useable billing data not being collected.
- -        Two (2) or more contiguous BTSs failing causing a loss of coverage.
- -        Ten percent (10%) or more of the total number of voice trunks (BTS and
                  switch) are out-of-service.
- -        Ten percent (10%) or more of the total number of any links (including
                  IS-41, ISUP, X.25 and SS7 are out of service.
- -        Total loss of access to one or more specific services because of a
                  fault condition in the MSC and related Equipment.
- -        Any BTS having a total failure in excess of thirty (30) minutes after
                  recovery attempts from the OMP are executed.

                      The Vendor must clear all E1 Emergency  Conditions  within
                      twelve  (12) hours of  notification  of their  occurrence.
                      Work must continue  without any cessation until the defect
                      causing  the  E1  Emergency  Condition  is  solved  or the
                      severity thereof is reduced to a "P1 Major Condition",  as
                      defined below, or less.

                (ii)  An E2 Emergency  Condition  (this roughly  corresponds  to
                      Severity   1   Conditions   in  the   Vendor's   ISO  9001
                      documentation)  means a problem  resulting from any one or
                      more of the following events:

- -        Loss of the duplex functionality for any equipment that is duplicated.
- -        Single BTS failing less than thirty (30) minutes that is not contiguous
            with another failed BTS.
- -        Loss of the master clock.
- -        Fifty percent (50%) or more of the equipped tape or disk drive units
            out-of-service.
- -        Loss of duplex recording of billing information.
- -        Inability to dump or initialize an office image (e.g., translations
            and/or software).
- -        Inability to perform critical maintenance procedures.
- -        Loss of all links within a single link-set.

                      The Vendor must clear all E2 Emergency  Conditions  within
                      twenty-four   (24)  hours  of   notification  of  such  E2
                      Emergency  Conditions.  Work  must  continue  without  any
                      cessation  until  the  defect  causing  the  E2  Emergency
                      Condition  is solved or the  severity  is  reduced to a P1
                      Major Condition or less.

                      (c)  In the event that an E1 Emergency Condition or an E2
Emergency Condition should remain unresolved  following  referral to the Vendor.
by the Owner,  the problem causing such  condition  must be  reported to the
levels of  management  set forth below (with  comparable  titles,  if different)
to ensure  all  available  resources necessary  to address the  problem  will be
committed  in  accordance  with the following:

             The following are the reporting levels if an E1 Emergency Condition
or an E2 Emergency  Condition is not resolved  within the time periods set forth
below, as amended from time to time with the reasonable acceptance of the Owner,
following referral thereof to the Vendor by the Owner:

                Vendor Contact           Vendor Contact Name   Telephone Number

One hour    -- Technical Assistance Mgr.  to be designated     to be designated
Two hours   -- Customer Service Director  to be designated     to be designated
Three hours -- Customer Service AVP       R.B. Andrews         (708) 713-1500
Four hours  -- Vice President             R.G. Garriques       to be designated

         (d) If the Owner reasonably determines that the Vendor has not provided
sufficient ETA to resolve any E1 Emergency  Condition or E2 Emergency  Condition
on a timely  basis,  the Owner will be entitled to withhold  all  payments  with
respect to the affected PCS System and/or PCS Sub-System then due or outstanding
prior to the date of such  determination  until  such  time as  adequate  ETA is
provided to the Owner to resolve such Emergency Condition.

         (e) If an E1 Emergency Condition or an E2 Emergency Condition exists in
a PCS System and/or PCS Sub-System  prior to Final Acceptance of such PCS System
or PCS  Sub-System,  as the  case may be,  the  Vendor  will use all  reasonable
efforts to deliver to the Owner each Software Upgrade and each Equipment Upgrade
developed by or on behalf of the Vendor to resolve any E1 Emergency Condition or
E2 Emergency  Condition within  forty-eight  (48) hours following  completion of
development  of  such  Software  Upgrades  or  availability  of  such  Equipment
Upgrades.

         (f) The term  "Non-Emergency  Services" includes providing to the Owner
any requested  technical  assistance and support,  remote  monitoring and outage
review consultation and the handling of CSRs.

         (g) Technical  assistance  and support must be provided for the purpose
of resolving  non-emergency problems defined below as "P1 Major Condition",  "P2
Significant Problem" and "P3 Minor Problem" which are reported to the Vendor.

                    (i)  P1  Major  Condition   (this  roughly   corresponds  to
                         Severity  1   Conditions   in  the  Vendor's  ISO  9001
                         documentation)  means  any  non-emergency   failure  of
                         specific  features or functions of the System,  any PCS
                         System,   any  PCS   Sub-System  or  any  Product  that
                         restricts  its  operations,  but  does not  render  the
                         System,  any  PCS  System,  any PCS  Sub-System  or any
                         Product inoperable, impact traffic capacity or coverage
                         or  require  significant  manual  intervention  for the
                         System,  any  PCS  System,  any PCS  Sub-System  or any
                         Product to operate  properly and in accordance with its
                         applicable  Specifications.  These  events will include
                         loss of diagnostic  capabilities  and loss of reporting
                         functions.  The Vendor will use all reasonable  efforts
                         to use by-pass or  work-around  procedures to alleviate
                         such P1 Major Condition until it is corrected and, upon
                         mutual  agreement  of  the  Parties,  the  Vendor  will
                         resolve  such  P1  Major  Condition   during  the  next
                         available   scheduled  Software  Upgrade  or  Equipment
                         Upgrade.

                    (ii) P2  Significant  Problem (this roughly  corresponds  to
                         Severity  2   Conditions   in  the  Vendor's  ISO  9001
                         documentation) means any non-emergency,  intermittently
                         occurring problem related to specific primary functions
                         or features or any inoperable  secondary functions that
                         do not have a significant adverse effect on the overall
                         performance  of the  System,  any PCS  System,  any PCS
                         Sub-System  or any Product.  The Vendor will  undertake
                         appropriate  and reasonable  efforts to correct such P2
                         Significant Problem.

                    (iii)P3 Minor Problem (this roughly  corresponds to Severity
                         3 Conditions  in the  Vendor's ISO 9001  documentation)
                         means any  non-emergency  problem  that does not affect
                         the  performance  or functions  of the System,  any PCS
                         System, any PCS Sub-System or any Product, and, despite
                         such  problem,  the  System,  any PCS  System,  any PCS
                         Sub-System  or any  Product is fully  operable  without
                         restrictions.   Such  P3  Minor  Problems  may  include
                         documentation  inaccuracies,  cosmetics, minor requests
                         for changes or  maintenance  requests.  The Vendor will
                         undertake appropriate and reasonable efforts to correct
                         such P3 Minor Problem.

         (h) Should a non-emergency  problem remain unresolved for the period or
periods of time set forth below  following  referral to the Vendor by the Owner,
such  problem  must be reported to the levels of  management  set forth below to
ensure all  available  resources  necessary  to  correct  such  problem  will be
committed to address such problem pursuant to the following:

         Non-emergency problems referred to the Vendor as a CSR will be resolved
based  upon the  priority  assigned  to them as  determined  by the  Owner or as
mutually agreed by the Parties and, to the extent reasonably  possible,  will be
incorporated into the next scheduled Software release.

                  2.26.4  ETA and CSR.  In the event  that  emergency  technical
support provided from the Vendor's technical support center is not sufficient to
resolve an E1 Emergency Condition,  the Vendor must send a technically qualified
person or persons to the site of such  emergency  condition or problem to assist
the  Owner's  employees  in solving  such  condition  or problem.  The  Vendor's
technically qualified person or persons must be on-site as soon as possible, but
in no event more than twenty-four (24) hours after notification to the Vendor by
the Owner, or at such later time as may be mutually agreed on by the Parties. In
the event that emergency  technical support provided from the Vendor's technical
support center is not sufficient to resolve an E2 Emergency Condition,  then the
Parties will  mutually  agree to a desired  course of action,  which may include
requiring  the Vendor to send a technically  qualified  person or persons to the
site of such emergency.

                  A CSR may be  submitted  by the  Owner to  request a repair or
work-around of an emergency  condition or repair of a non-emergency  problem, or
to  request a Software  Upgrade or an  Equipment  Upgrade or other  Software  or
Equipment operational enhancement. The Owner's CSRs will define the condition or
problem  and state  whether  the Owner  considers  the CSR to be for a  Software
Upgrade or an  Equipment  Upgrade or other  Software  or  Equipment  operational
enhancement.  Changes  to the  System,  any PCS  System  or any  PCS  Sub-System
resulting from any CSR must be fully tested and accepted in accordance  with the
Specifications.  The Vendor must respond to the submission of a CSR by the Owner
within five (5) Business Days,  acknowledging  receipt of the CSR. Within thirty
(30) days of receipt of the CSR, the Vendor will respond to the CSR  summarizing
the  Vendor's  intended  actions  to handle  the CSR. A CSR may result in System
fixes or enhancements,  or in Product modifications reasonably acceptable to the
Owner.

                  Notwithstanding  the above, no event, lack of functionality or
failure of the Test-bed Laboratory will be assigned as an E1 Emergency Condition
or E2 Emergency  Condition.  Any such event,  lack of  functionality  or failure
applicable to the Test-bed Laboratory,  which would otherwise be assigned such a
category in accordance with the definitions  above,  will be assigned a P1 Major
Condition.

forth in this Contract or as otherwise mutually agreed between the Parties,  PCS
Products to enable the Owner to expand the System  and/or any PCS System  and/or
any PCS  Sub-System  and/or  any  part  thereof,  which  Products  will  provide
equivalent  functionality for and will be compatible with the System or any such
PCS System or PCS  Sub-System  at such time.  Nothing  herein  will be deemed to
prohibit the Vendor from  designating  any specific PCS Products as Discontinued
Products in accordance with Section 10 of this Contract.
- - ------------------------------------------------------------------------------

         2.28  Review of  Contract.  The  Vendor  has  examined  in  detail  and
carefully studied and compared the Contract with all other information furnished
by the Owner  and has  promptly  reported  to the  Owner  any  material  errors,
inconsistencies  or  omissions  so  discovered  or  discovered  by  any  of  the
Subcontractors.  The Vendor  will not  prosecute  any Major  Portion of the Work
knowing  that it  involves a material  error,  inconsistency  or omission in the
Contract  without prior written notice to and approval by the Owner.  If for any
reason the Vendor violates this subsection 2.28, the Vendor will, in addition to
being subject to any other remedies of the Owner, assume responsibility for such
violation  and,  in such case,  will be deemed to have  waived any claims for an
adjustment in any of the  Specifications  and/or System  Standards which results
directly from any such error,  inconsistency  or omission.  This subsection 2.28
does not,  nor will be deemed  to, in any manner  limit the terms of  subsection
2.39.

         2.29 Licenses, Permits and Approvals.  Except as otherwise provided for
herein  with  respect to Site  Acquisition,  Microwave  Relocation  and  Network

safety or use of the Products,  the System, any PCS System or any PCS Sub-System
throughout  the  United  States  or in any state or any  political  sub-division
thereof will be the sole responsibility of the Vendor. Prior to the commencement
of any Work and/or other  activities by the Vendor or any of its  Subcontractors
in connection  with or pursuant to this Contract,  upon request of the Owner the
Vendor will furnish the Owner with  evidence that such  Applicable  Permits have
been  obtained  and are in full force and effect to the extent  that  Applicable
Permits are necessary for the  commencement  or undertaking of such  activities,
and from time to time thereafter the Vendor,  upon the reasonable request of the
Owner,  will  provide such  further  evidence as the Owner will deem  reasonably
necessary.

         2.30  Eligibility  under  Applicable Laws and Applicable  Permits.  The
Vendor will be responsible  for ensuring that the Vendor and its  Subcontractors
are and remain  eligible  under all Applicable  Laws and  Applicable  Permits to
perform the Work under this Contract in the various jurisdictions involved.

         2.31 Customs Approvals.  The Owner agrees to reasonably assist, so long
as such  assistance  will not involve the incurrence of any costs or expenses by
the  Owner,  the  Vendor to obtain  and  maintain  (i)  Applicable  Permits  for
importation into the Products on a duty and customs free basis and (ii) entry or
work permits,  visas or  authorizations  required for  personnel  engaged by the
Vendor to perform Work under this Contract.

         2.32  Owner  Participation.  In  addition  to the right of  observation
contained in subsection 9.4 hereof, the Owner will be entitled to participate in
the Vendor's  research and  development  activities  (subject to the  reasonable
acceptance  of the  Vendor)  and  product  development  and  testing  activities
pursuant  to this  Contract  (other than  research  and  development  activities
originated by another  Customer which is  proprietary  to such other  Customer);
provided that such  observation and  participation  will not affect the Vendor's
responsibilities  and warranties hereunder and will not otherwise interfere with
the Vendor's  research and  development  activities.  Nothing  contained in this
subsection 2.32 purports to grant the Owner rights to the Vendor's  research and
development  other than such rights  otherwise  granted to the Owner pursuant to
the terms of this  Contract or as  otherwise  mutually  agreed by the Parties at
such time.

         2.33 New  Development  Advisory  Board.  In order  to  accommodate  the
Owner's participation pursuant to this Contract,  including, without limitation,
pursuant to  subsections  2.11 and 2.32, the Owner and the Vendor will establish
an NDAB within sixty (60) days of the  Effective  Date.  The purpose of the NDAB
will be to  review  the  development  requirements  and high  level  development
milestones,  to ensure that the Vendor understands the Owner's  requirements for
each PCS System, each PCS Sub-System the System,  and/or any extensions thereto,
including, without limitation, any subsequent Products and/or enhancements.  The
NDAB  will  provide  an  executive  forum  to  discuss   product  ideas,   Owner
requirements  and  its  recommended  development   prioritization  for  improved
infrastructure-based  subscriber  features and System  features,  functions  and
capabilities. The focus of the NDAB will be on System features and services, new
PCS  Products,   System  enhancements,   critical  operational  issues,   future
developments  beyond CDMA cellular  without the need for System additions and on
such other matters as the Parties mutually agree upon from time to time.

         2.34  Market  Development  Manager.  The Vendor  will  provide a market
development  manager to  coordinate  the  efforts  of the Vendor in meeting  its
obligations  relating to the NDAB who will  specifically  focus on new Products,
CDMA  services  and   features.   Such  market   development   manager  must  be
knowledgeable  in CDMA  technology and the Owner's System and must work closely,
and on a regularly  scheduled  basis,  with the Owner's senior  engineering  and
marketing personnel on feature development,  feature roll-out,  future road maps
for PCS Products, and any other marketing aspect of providing PCS that the Owner
believes  is  beneficial  to the System  and/or  any PCS  System  and/or any PCS
Sub-System  at such  time.  The  Vendor's  market  development  manager  and the
manager's  staff will serve as the  Owner's  direct  liaison  with the Vendor to
ensure that the Vendor's product  development  teams are focusing on the Owner's
priorities  as  described  to the Vendor by the Owner  from time to time  either
through  the NDAB or by any  other  means  acceptable  to the  Parties.  Nothing
contained  in this  subsection  2.34 will in any way  limit  and/or  modify  the
Owner's  ability to enforce  its rights  under  this  Contract  or to  otherwise
maintain contacts with the Vendor in any other way it sees fit.

         2.35  Further  Assurances.  The Vendor  will  execute  and  deliver all
further instruments and documents,  and take all further action,  including, but
not limited to,  assisting the Owner in filing  notices of  completion  with the
appropriate  state and local lien  recording  offices,  that may be necessary or
that the Owner may reasonably  request in order to enable the Vendor to complete
performance  of the  Work  or to  effectuate  the  purposes  or  intent  of this
Contract.

         2.36  Liens and Other Encumbrances.  (a)  In consideration of the mut-
ual undertakings herein and other good and valuable consideration the receipt
and sufficiency of which is hereby acknowledged, the Vendor:

               (i)  covenants  and  agrees to  protect  and keep free the System
         and/or  any  PCS  System  and/or  any  PCS  Sub-System  and any and all
         interests and estates  therein,  and all improvements and materials now
         or hereafter placed thereon under the terms of this Contract,  from any
         and all  claims,  liens,  charges  or  encumbrances  of the  nature  of
         mechanics, labor or materialmen liens or otherwise arising out of or in
         connection with performance by any Subcontractor, including services or
         furnishing  of any materials  hereunder,  and to promptly have any such
         lien released by bond or otherwise;

              (ii)  will  give   notice   of  this   subsection   2.36  to  each
         Subcontractor   before  such  Subcontractor   furnishes  any  labor  or
         materials  for  the  System  and/or  any  PCS  System  and/or  any  PCS
         Sub-System; and

             (iii) will make any and all  filings  reasonably  requested  by the
         Owner in order that the Owner may take  advantage of the relevant local
         mechanics' lien waiver  procedures with respect to mechanics'  liens of
         any such Subcontractor.

         (b) If any laborers', materialmen's,  mechanics', or other similar lien
or claim thereof is filed by any Subcontractor,  the Vendor will cause such lien
to be  satisfied  or  otherwise  discharged,  or will  file a bond  in form  and
substance  satisfactory to the Owner in lieu thereof within ten (10) days of the
Vendor's  receipt  of  notice  of such  filing.  If any  such  lien is  filed or
otherwise  imposed,  and the Vendor does not cause such lien to be released  and
discharged forthwith, or file a bond in lieu thereof, then, without limiting the
Owner's  other  available  remedies,  the  Owner  has  the  right,  but  not the
obligation,  to pay all sums  necessary to obtain such release and  discharge or
otherwise  cause the lien to be  removed or bonded to the  Owner's  satisfaction
from funds retained from any payment then due or thereafter to become due to the
Vendor.

         (c) The Owner  reserves  the right to post or place  within  the System
and/or any PCS System and/or any PCS Sub-System notices of non-responsibility or
to do any other act  required  by  Applicable  Law,  to exempt the Owner and the
System from any liability to third parties by reason of any work or improvements
to be performed or furnished hereunder; provided that failure by the Owner to do
so will  not  release  or  discharge  the  Vendor  from  any of its  obligations
hereunder.

         2.37 Forecasting and Ordering. Throughout the Term of this Contract, on
a monthly basis  commencing on the  Effective  Date,  the Owner will provide the
Vendor with rolling  twelve-month  forecasts of its ongoing  Product and Service
requirements. Such forecasts will, to the extent applicable, include, but not be
limited  to, the Owner's  Site  Acquisition,  Switch  Site Ready  Date,  Network
Interconnection and Microwave  Relocation progress to such date. Upon the review
and reasonable  acceptance of such forecasts by the Vendor pursuant to the terms
of this  Contract,  the Owner will have the right,  but not the  obligation,  to
confirm to the Vendor its orders for the Products and Services set forth in such
forecasts  pursuant  to the  Owner's  delivery  to the Vendor of formal  written
orders  specifying  the Products  and/or  Services to be purchased in connection
with  the  terms  of this  Contract.  The  Vendor's  obligation  to  deliver  in
accordance  with  accepted  forecasts  will be subject to receipt of the Owner's
orders in accordance with the applicable ordering procedures. If the Owner fails
to deliver any forecast  pursuant to this  subsection  2.37 for any reason,  the
Vendor  will be  responsible  for  asking  the Owner to  actually  deliver  such
forecast to the extent it requires such forecast at such time.

         2.38 Microwave Relocation; Network Interconnection. (a) The Vendor will
not be responsible for Microwave Relocation within the System.  Unless otherwise
waived by the Owner,  however,  completion of Microwave  Relocation in any given
System Area or System Sub-Area will be a prerequisite to the commencement of the
Substantial  Completion testing to be performed by the Vendor in accordance with
Exhibit B3 in such System Area or System  Sub-Area.  The Owner may at its option
choose instead to modify the System performance criteria as set forth in Exhibit
F by way of a Change  Order in order to account for the failure to fully  and/or
satisfactorily  complete Microwave  Relocation in any such System Area or System
Sub-Area  such  that  Substantial  Completion  testing  in  accordance  with the
requirements of Exhibit B3 may proceed.  Notwithstanding  anything stated herein
to the  contrary  (other  than clause (b) below),  the  Owner's  failure  and/or
inability  to fully  complete  Microwave  Relocation  in any such System Area or
System  Sub-Area  within  twelve  (12)  months of  Milestone  6 (as set forth in
Exhibit A1) (the "Microwave  Delay Period") will entitle the Vendor to otherwise
commence  Substantial  Completion  testing (as deemed applicable and appropriate
pursuant to good faith  mutual  agreement  between the Parties at such time) for
the PCS System or PCS Sub-System in such System Area or System Sub-Area,  as the
case may be, in  accordance  with Exhibit B3.  Pursuant to the  requirements  of
Exhibits  A1, B1 and B3 with  respect  to any PCS  System or any PCS  Sub-System
within the System the Owner may, upon the prior  written  request of the Vendor,
consent (such consent not to be unreasonably  withheld) to extend the scheduling
of the Vendor's  Substantial  Completion  testing by not more than an additional
sixty (60) days  pursuant to Milestone 8 in the event that more than ten percent
(10%) of the System  Element  Sites in such PCS System or PCS  Sub-System as set
forth in the Final  Site  Count for such PCS  System or PCS  Sub-System  require
Vendor  optimization  pursuant to Exhibit B1 that was  otherwise  delayed due to
incomplete Microwave Relocation in such PCS System or PCS Sub-System immediately
prior to the date  scheduled  for  Substantial  Completion  testing  pursuant to
Milestone 8 (as set forth on Exhibit A1).

         (b) The Vendor  will not be  responsible  for  Network  Interconnection
within the System.  In any given System Area or System  Sub-Area,  completion of
Network  Interconnection  in such System Area or System  Sub-Area at least sixty
(60) days (or as  otherwise  mutually  agreed  between the Parties at such time)
prior to Milestone 7 (as set forth on Exhibit A1) will be a prerequisite  to the
Vendor's  obligation  pursuant  to the terms of this  Contract  to  successfully
achieve  Milestone  7 (as set forth in Exhibit A1) in such System Area or System
Sub-Area.

         2.39 Vendor To Inform Itself Fully;  Waiver of Defense.  (a) The Vendor
will be deemed to have notice of and to have fully  examined  and  approved  the
Specifications  and all other  documents  referred to herein,  and all drawings,
specifications,  schedules,  terms and conditions of this Contract,  regulations
and other  information  in  relation  to this  Contract  and/or any  amendments,
modifications or supplements  thereto at any time on or after the Effective Date
and  to  have  fully  examined,  understood  and  satisfied  itself  as  to  all
information  of which the Vendor is aware or should have been aware and which is
relevant  as to the risks,  contingencies  and other  circumstances  which could
affect this Contract and in particular the  installation of the System,  any PCS
System,  any PCS  Sub-System  or any part  thereof.  The Owner,  its  directors,
officers,  employees  and  agents  and all of them have no  liability  in law or
equity  or in  contract  or in tort  with  respect  to any such  specifications,
drawings, information, risks, contingencies or other circumstances.

         (b) The fact  that the  Owner may have  prepared  or taken  part in the
preparation  of  Specifications,   documents,  drawings,  Engineering,  designs,
specifications,   schedules,   terms  or  conditions,  or  may  have  designated
particular  types of Products  and/or  Services  to be  furnished  hereunder  or
designated particular manufacturers or suppliers of Products or Services, or may
have  taken  part  in the  designation  of any  particular  Subcontractor(s)  or
subcontractor(s),  or given  vetoes or approvals  with  respect to the Work,  or
otherwise  become  involved in the Work,  will not give rise to any claim by the
Vendor or any  Subcontractor  or any  defense to any  warranty  or other  claims
asserted  against  the Vendor or any  Subcontractor  to the extent that any such
claim or defense arises out of any specifications, drawings, documents, or other
information,  which  the  Vendor is deemed  to have had  notice of  pursuant  to
subsection 2.39(a) above and with respect to any such information  arising after
the Effective Date which the Vendor had a reasonable opportunity to review.

         2.40 CMI/HIC.  From time to time  throughout  the Term of this Contract
the  Parties may  mutually  agree as to the  incorporation  and  integration  of
CMI/HIC into the System in accordance with Exhibit D.

         2.41 Site Acquisition Delay Testing. In any given System Area or System
Sub-Area within the Initial System,  in the event Site  Acquisition  Substantial
Completion  is delayed  more than one  hundred  and fifty  (150) days beyond the
forecasted date for Site Acquisition  Substantial Completion as set forth in the
M5 Forecast (the "Site  Acquisition  Delay Period")  provided to the Vendor with
the Build Notice applicable to such System Area or System Sub-Area,  as the case
may  be,  due  solely  to the  Owner's  inability  to  achieve  sufficient  Site
Acquisition in such System Area and/or System Sub-Area,  as the case may be, the
Vendor will have the right,  but not the  obligation,  to  commence  Substantial
Completion testing (as deemed applicable and appropriate  pursuant to good faith
mutual  agreement  between  the  Parties  at such  time  but in any  event to be
completed within thirty (30) days of such  commencement) for that portion of the
otherwise incomplete PCS System or PCS Sub-System,  as the case may be, in which
the Vendor has (i) completed all applicable Facilities  Preparation Services and
(ii) fully Installed,  to the extent possible at such time, all such Products to
be Installed by the Vendor or its  Subcontractors on otherwise fully constructed
System Element  Locations  within such PCS System or PCS Sub-System.  Subject to
Section  6,  in the  event  the  Vendor  successfully  completes  such  modified
Substantial  Completion  testing for such  Installed  portion of such  otherwise
incomplete PCS System or PCS Sub-System,  as the case may be, pursuant to and in
accordance with this subsection 2.41 and Exhibit B3, the Vendor will be entitled
to such  portion  of the  payments  that  otherwise  would be made by the  Owner
pursuant to subsection  6.3(b) as applicable only to those Services and Products
actually  provided by the Vendor pursuant to and in accordance with the terms of
this Contract in such portion of the otherwise  incomplete PCS System and/or PCS
Sub-System,  as the case may be,  that was  subject to testing  pursuant to this
subsection 2.41. Nothing contained herein to the contrary will in any way modify
the  Vendor's  obligations  as to the  completion  and testing of the  remaining
portion of such PCS System  pursuant to and in accordance with the terms of this
Contract,  including  but not  limited to the  Project  Milestones  set forth in
Exhibit A1. Nothing contained herein to the contrary will in any way require the
Owner to pay the Vendor amounts already paid or otherwise  provided for pursuant
to any other provision of this Contract.


                              SECTION 3 AFFILIATES

         3.1  Additional  Affiliates.  On a quarterly  basis  commencing  on the
Effective Date and during the term of this Contract, the Owner may, upon fifteen
(15) days' prior written notice to the Vendor, designate any Person who has been
licensed or has access to or rights to use licenses for PCS in the United States
which is not an Initial  Affiliate as an "Additional  Affiliate";  provided that
the  Vendor  will have a  reasonable  opportunity  to review  and  approve  such
designation,  such  approval  not to be  unreasonably  withheld,  based upon (i)
reasonable credit criteria within the context of the PCS industry, (ii) the fact
that such proposed Additional  Affiliate has not in the past materially breached
prior  material  agreements  with the Vendor,  (iii) the fact that the  proposed
Additional  Affiliate  is  not,  at the  time of such  determination,  a  direct
competitor  to the Vendor in the wireless  telecommunications  business and (iv)
the fact that the  proposed  Additional  Affiliate  is not,  at the time of such
determination, otherwise engaged with the Vendor in a material agreement for the
purchase and/or supply of PCS CDMA wireless technology;  and provided,  further,
that (x) the Owner,  any  Partner or any  Initial  Affiliate  has at least a ten
percent (10%) equity ownership in such Person,  (y) such Person is controlled by
or under the common control with the Owner, any Partner or any Initial Affiliate
or (z) there exists  between the Owner and such Person an  Additional  Affiliate
Arrangement.

         3.2  Agreements  with  Initial  Affiliates.  During  the  term  of this
Contract, the Owner will have the right, but not the obligation, to require that
the Vendor enter into separate agreements with any Initial Affiliate  designated
by the Owner (each, an "Initial Affiliate Agreement") for the supply of Products
and  Services on similar  terms and  conditions  as those set forth  herein that
relate to the initial  build-out of the Initial  System as set forth on Schedule
4;  provided  that the Vendor  will not be  required  to include in any  Initial
Affiliate Agreement any provisions  substantially  similar to those set forth in
subsections  2.3(a),  2.5, 2.23 (but only to the extent of the specific  amounts
set forth in such subsection  2.23),  3.1, 3.3, 11.7, 15.1, 21.1, 24.1 and 27.5;
and provided  further that after the date on which Final  Acceptance of the last
PCS System to reach Final Acceptance has occurred,  Initial Affiliate Agreements
(whether  or not  executed  prior to such  date)  need  not  contain  or  retain
substantially  the same terms and  conditions as those set forth herein,  except
for those terms and  conditions  related to pricing and  warranties  as are then
available to the Owner  pursuant to this  Contract.  Any Initial  Affiliate that
enters into an Initial  Affiliate  Agreement with the Vendor will have the right
to choose  among the  Products  and  Services  offered  to the Owner  under this
Contract solely for use within the Nationwide Network.

         3.3  Agreements  with  Additional  Affiliates.  During the term of this
Contract, the Owner will have the right, but not the obligation, to require that
the  Vendor  enter  into  separate  agreements  with  any  Additional  Affiliate
designated by the Owner (each,  an  "Additional  Affiliate  Agreement")  for the
supply of Products and Services at similar price and warranty  terms as are then
available to the Owner pursuant to the terms of this  Contract.  The Vendor must
enter into good faith  negotiations  for the  establishment  of such  Additional
Affiliate  Agreements  with  any such  Additional  Affiliate  promptly  upon the
designation  of such  Additional  Affiliate  by the Owner and upon notice to the
Vendor  that such  Additional  Affiliate  desires  to enter  into an  Additional
Affiliate  Agreement.  Any  Additional  Affiliate that enters into an Additional
Affiliate  Agreement  with the  Vendor  will have the right to choose  among the
Products and Services  offered to the Owner under this  Contract  solely for use
within the Nationwide Network.

         3.4 Affiliate Rights.  Notwithstanding anything herein contained to the
contrary,  Affiliates  will not be  deemed  third  party  beneficiaries  to this
Contract or otherwise have any rights hereunder.  Only the Owner may designate a
Person as an Affiliate in  accordance  with the terms of this Section 3 and only
the Owner has the right  and/or  the  ability to  enforce  any rights  hereunder
against the Vendor.


                            SECTION 4 SUBCONTRACTORS

         4.1 Subcontractors. The Vendor will select Subcontractors in connection
with the performance of the Work such that all Products and Services provided by
any  such   Subcontractors   meet  the  System  Standards  and  reliability  and
performance  requirements  set forth in this Contract.  Regardless of whether or
not the Vendor obtains approval from the Owner of a Subcontractor or whether the
Vendor uses a  Subcontractor  recommended  by the Owner,  use by the Vendor of a
Subcontractor will not, under any  circumstances:  (i) give rise to any claim by
the Vendor against the Owner if such  Subcontractor  breaches its subcontract or
contract  with the  Vendor;  (ii) give  rise to any claim by such  Subcontractor
against the Owner;  (iii) create any contractual  obligation by the Owner to the
Subcontractor;  (iv) give rise to a waiver by the Owner of its  rights to reject
any Defects or  Deficiencies  or Defective  Work;  or (v) in any way release the
Vendor from being solely  responsible  to the Owner for the Work to be performed
under this Contract.

         4.2 The Vendor's  Liability.  The Vendor is the general  contractor for
the Work and remains responsible for all of its obligations under this Contract,
including the Work,  regardless of whether a subcontract or supply  agreement is
made or whether the Vendor  relies  upon any  Subcontractor  to any extent.  The
Vendor's use of  Subcontractors  for any of the Work will in no way increase the
Vendor's  rights or diminish the Vendor's  liabilities to the Owner with respect
to this Contract,  and in all events, except as otherwise expressly provided for
herein, the Vendor's rights and liabilities  hereunder with respect to the Owner
will be as though the Vendor had itself  performed such Work. The Vendor will be
liable for any delays caused by any  Subcontractor as if such delays were caused
by the Vendor.

         4.3 No Effect of Inconsistent Terms in Subcontracts.  The terms of this
Contract will in all events be binding upon the Vendor regardless of and without
regard to the existence of any inconsistent  terms in any agreement  between the
Vendor and any Subcontractor  whether or not and without regard to the fact that
the  Owner  may  have  directly  and/or   indirectly  had  notice  of  any  such
inconsistent term.

         4.4  Assignability of Subcontracts to Owner. Each agreement between the
Vendor and a Subcontractor  must contain a provision  stating that, in the event
that the  Vendor is  terminated  for  cause,  convenience,  abandonment  of this
Contract or otherwise,  (i) each  Subcontractor will continue its portion of the
Work as may be requested by the Owner and (ii) such agreement permits assignment
thereof without penalty to the Owner and, in order to create security interests,
to the Other Vendors, in either case at the option of the Owner and for the same
price and under the same terms and  conditions as  originally  specified in such
Subcontractor's agreement with the Vendor.

         4.5 Removal of Subcontractor or  Subcontractor's  Personnel.  The Owner
has the right at any time to require removal of a Subcontractor  and/or any of a
Subcontractor's  personnel from Work on the System upon  reasonable  grounds and
reasonable  prior notice to the Vendor.  The exercise of such right by the Owner
will have no effect on the provisions of subsections 4.1 and 4.2.

         4.6 Subcontractor Insurance. The Vendor must require its Subcontractors
to  obtain,  maintain  and keep in force  during  the time they are  engaged  in
providing Products and Services hereunder adequate insurance coverage consistent
with  Section  18 and  Schedule 6  (provided  that the  maintenance  of any such
Subcontractor  insurance  will not relieve  the Vendor of its other  obligations
pursuant  to Section 18 and  Schedule  6). The  Vendor  will,  upon the  Owner's
request, furnish the Owner with evidence of such insurance in form and substance
reasonably  satisfactory to the Owner. All such insurance will be subject to the
Owner's approval.  All Subcontractors  must be of bondable financial  condition.
Nothing  herein  will be deemed  to bar the  Vendor  or any  Subcontractor  from
obtaining  such  insurance  on a project  basis  for each of the  Subcontractors
participating in such project.

         4.7 Review and Approval not Relief of Vendor Liability. Any inspection,
review or approval by the Owner  permitted under this Contract of any portion of
the Work by the Vendor or any  Subcontractor  will not relieve the Vendor of any
duties, liabilities or obligations under this Contract, but nothing contained in
this subsection 4.7 will be deemed a bar of any waiver given by the Owner to the
Vendor pursuant to and in accordance with the terms of this Contract.

         4.8  Vendor  Warranties.  Except as  otherwise  expressly  provided  in
Section 17, the  warranties of the Vendor  pursuant to Section 17 will be deemed
to apply to all Work  performed  by any  Subcontractor  as though the Vendor had
itself performed such Work. Except as otherwise specifically provided in Section
17, the Parties agree that such warranties  will not be enforceable  merely on a
"pass-through"  basis. The Owner may, but will not be obligated to, enforce such
warranties of any Subcontractor to the extent that the Owner determines that the
Vendor is not paying and/or  performing its  warranties;  provided that any such
election  by the Owner will not  relieve  the  Vendor  from any  obligations  or
liability with respect to any such warranty.

         4.9 Payment of Subcontractors. The Vendor must make all payments to all
Subcontractors (except in the case of legitimate disputes between the Vendor and
any such Subcontractor  arising out of the agreement between the Vendor and such
Subcontractor) in accordance with the respective  agreements  between the Vendor
and its  Subcontractors  such that  Subcontractors  will not be in a position to
enforce  liens  and/or other  rights  against the Owner,  the System or any part
thereof.


                           SECTION 5 TERM OF CONTRACT

         5.1 Initial  Term.  The initial  term of this  Contract  (the  "Initial
Term") is ten (10)  years  from the  Effective  Date,  subject  to the terms and
conditions of this  Contract  including,  without  limitation,  the  termination
provisions set forth in Section 24.

         5.2 Renewal.  This  Contract is subject to renewal for one year periods
(all such periods plus the Initial Term, the "Term") following the expiration of
the Initial  Term, on the same terms and  conditions  contained  herein,  unless
either Party gives notice to each other Party of its intention not to renew this
Contract  within  ninety (90) days prior to the  expiration  of the then current
Term.

                          SECTION 6 PRICES AND PAYMENT

         6.1 Prices.  The prices for the Work to be  performed  pursuant to this
Contract  (collectively,  the "Contract  Price") are as set forth on Schedules 2
and 3,  subject to the price  variation  provisions  contained  on  Schedule  2.
Notwithstanding  the  prices  set forth on  Schedules  2 and 3 and the  Contract
Price,  the Vendor will  provide  the Owner  credits in  aggregate  value not to
exceed [ ] dollars ($[ ]) to purchase any Products in the following System Areas
(and any and all System Sub-Areas included therein) and in the following amounts
per such System Areas:

                       System Area              Credit Amount

                         Detroit                   $[ ]
                        Milwaukee                  $[ ]
                          Denver                   $[ ]
                        Salt Lake                  $[ ]
                         Spokane                   $[ ]

The Owner is also entitled to additional  purchase  credits of up to [_________]
dollars  ($[__________]) to be applied in the Owner's discretion to the purchase
of any Products in any or all of the above listed  System Areas (and any and all
System Sub-Areas included therein). At any time during the Term of this Contract
that  the  Owner  wishes  to  apply  the  purchase  credits  referenced  in this
subsection  6.1 to any of its  Product  purchases  for the System  Areas  listed
immediately  above,  the Owner must notify the Vendor of its intent to do so and
it  will  be the  Vendor's  sole  responsibility,  throughout  the  Term of this
Contract,  to keep account of the remaining  purchase  credits  available to the
Owner.  Prices for the Work not  otherwise set forth on Schedules 2 or 3, if not
otherwise set forth in this Contract,  will be no greater than the Vendor's best
list prices then in effect at the time of ordering by the Owner (as  established
by the Vendor's  then  applicable  Customer  Price Guide for sales in the United
States) and at discounts  otherwise  provided to the Owner pursuant to the terms
of this Contract.  Notwithstanding the foregoing,  the aforesaid credits may not
be applied to the purchase of any OTAF Products or Services  and/or any Actiview
Products or Services.

         6.2 Price Reduction.  The Contract Price will be reduced by all amounts
saved as a result  of  Engineering  changes  suggested  by the  Owner  which are
incorporated  into the  Specifications  by the Vendor  provided  that the Vendor
reasonably   believes   that  such  changes  will  not  make  it  impossible  or
impracticable  to  comply  with  any of its  obligations  under  this  Contract,
including,   without  limitation,  those  Vendor  obligations  relating  to  the
performance  criteria  applicable to the System. Any reduction in Contract Price
pursuant to the preceding sentence will be agreed upon promptly by the Owner and
the Vendor.  Failure of the Parties to mutually  agree to such price  reductions
within  ten (10) days from the date the Owner  delivered  written  notice to the
Vendor of the need for such  price  reduction  due to  incorporated  Engineering
changes  will  result in the  automatic  reference  of such  matter  to  dispute

and criteria set forth in Exhibit D within thirty-two and one-half (32-1/2) days
of completion of the Facilities Preparation Services pursuant to Milestone 6 (as
set forth in Exhibit A1) in such PCS System and/or PCS Sub-System.

         8.2 No  Interference.  The Vendor will  install the  Products and build
each of the PCS  Systems  and PCS  Sub-Systems  so as to cause  no  unauthorized
interference  with or obstruction to lands and thoroughfares or rights of way on
or near which the Installation  work may be performed.  The Vendor must exercise
every  reasonable  safeguard  to avoid  damage to  existing  facilities,  and if
repairs or new construction are required in order to replace  facilities damaged
by the Vendor due to its carelessness,  negligence or willful  misconduct,  such
repairs or new construction will be at the Vendor's sole cost and expense.


         SECTION 9  ACCEPTANCE TESTING AND ACCEPTANCE

         9.1 Acceptance Testing.  The Vendor must carry out the Acceptance Tests
on the Products, the PCS Systems and the PCS Sub-Systems as specified in Exhibit
B3 and each PCS System and PCS Sub-System must successfully  achieve  acceptance
(including  Substantial  Completion and Final Acceptance) in accordance with the
terms of Exhibit B3.

         9.2 Costs and Expenses. The costs and expenses of such Acceptance Tests
will be borne by the  Vendor,  and the Owner  will not be  charged or billed for
such costs and expenses,  except to the extent that such charges or expenses are
not included in the Contract Price pursuant to and in accordance  with the terms
of this  Contract.  If the  Acceptance  Tests  performed  by the  Vendor are not
satisfied  in  accordance  with the relevant  requirements  of Exhibit B3 or are
otherwise  inconclusive in the reasonable  judgment of the Owner, the Owner will
have the right to order further Acceptance Tests at the sole cost and expense of
the Vendor.

         9.3  Notification.  The Vendor  will notify the Owner at least ten (10)
days prior to the performance of any Acceptance Tests.  Prior to or at the first
practicable  date  after such  notification,  the Vendor and the Owner will each
agree  upon  and  approve  any test  forms to be used as part of the  particular
Acceptance Test being conducted.

         9.4 Presence at  Acceptance  Tests.  The Owner and its  representatives
will be  permitted to witness and have  unrestricted  access to the Vendor's and
its  Subcontractors'  Acceptance  Tests,  provided  that  no  such  access  will
materially  interfere  with or cause undue delay of the Vendor's  Work.  Nothing
herein will be deemed to require the Vendor to reimburse the Owner for any costs
incurred  by the  Owner  in  the  Owner's  participation  in or  observation  of
Acceptance  Tests or other  tests  performed  by the Vendor  pursuant  to and in
accordance with the terms of this Section 9.

         9.5 Correction of Defects. (a) If any Acceptance Test is not satisfied,
the Vendor will, at its sole cost and expense, (i) in writing,  notify the Owner
of such failure,  and (ii) promptly  correct  whatever  Defects or  Deficiencies
caused such  Acceptance  Test not to be satisfied.  After such  correction,  the
Vendor must (i) repeat at its sole cost and expense the failed  Acceptance Tests
and as many other  Acceptance Tests as are necessary to ensure in the reasonable
opinion of the Owner  that such  correction  made by the  Vendor  would not have
affected the outcome of such other Acceptance Tests, and (ii) in writing, notify
the  Owner  as to what  correction  was  made and  what  Acceptance  Tests  were
repeated.

         (b) If Final  Acceptance of a PCS System and/or PCS Sub-System,  as the
case may be, cannot be achieved after Substantial  Completion of such PCS System
or PCS Sub-System  (provided that the Vendor will have fully built-out the Final
RF Engineering  Plan in accordance  with the Final Site Count in accordance with
the terms of this Contract)  because such PCS System or PCS  Sub-System,  as the
case may be,  fails to meet  applicable  performance  criteria  as set  forth in
Exhibit  F, but would do so with only the  implementation  and  installation  of
additional Base Stations at additional  System Element  Locations over and above
the Final Site Count for such PCS System or PCS Sub-System,  as the case may be,
the Owner  will have the  right,  in its sole and  absolute  discretion,  to (i)
finally  accept such PCS System  and/or PCS  Sub-System,  as the case may be, in
which case the Parties will mutually agree in good faith on revised  performance
criteria  for such PCS  System  or PCS  Sub-System,  as the case may be, or (ii)
require the Vendor to continue to work (in which case Final  Acceptance  of such
PCS  System  or PCS  Sub-System,  as the  case  may be,  will be  delayed  until
completion  of the work and  testing  contemplated  herein and in Exhibit B3) to
cause such PCS System or PCS  Sub-System,  as the case may be, to perform at the
applicable  levels of the then  existing  performance  criteria  as set forth in
Exhibit F, in which case, the required  additional  Base Stations and additional
System Element Locations will be treated as provided for in subsections  17.5(c)
and 17.10. Any additional Base Station(s) paid for by the Owner pursuant to this
subsection  9.5(b)  (which would only have to be paid for  (including  any costs
associated  with the  installation  thereof)  by the Owner  upon the  subsequent
achievement  of Final  Acceptance  by the Vendor in  accordance  with Exhibit B3
which  such  payment  will be made  with the  payments  otherwise  made on Final
Acceptance  pursuant to Section 6) will be offset against the number of new Base
Stations that may  subsequently  be for the account of the Owner pursuant to the
terms of  subsection  17.5(c).  If the Parties are unable to agree upon  revised
performance  criteria  as  provided  in clause  (i) above,  the  matter  will be
resolved in accordance with the provisions of subsection 23.3.

         9.6  Acceptance  Certificate.  Upon the  successful  completion  of the
Acceptance  Tests for a PCS System,  and/or a PCS Sub-System or any part thereof
conducted  by the  Vendor,  the Vendor  must  submit to the Owner an  Acceptance
Certificate  certifying  that (i) such Acceptance  Tests have been  successfully
completed,  (ii) the Work so tested has been  completed in  accordance  with the
terms of this Contract, and (iii) if applicable,  that the remainder of the Work
is continuing in accordance with the Project  Milestones set forth on Exhibit A.
Upon its reasonable satisfaction that such Acceptance Certificate is correct and
complete,   the  Owner  will  acknowledge  such  certification  by  signing  the
Acceptance  Certificate.  In the event of any  dispute as to the  results of any
Acceptance  Tests,  such  dispute  will  be  resolved  pursuant  to the  dispute
resolution mechanisms set forth in Section 23 including, but not limited to, the
Third Party Engineer review mechanism set forth in subsection 23.3.

         9.7 AS Acceptance Testing and Acceptance. (a) After installation of the
AS  Software,  or any part  thereof as set forth in  Appendix  K, the Owner will
carry out  Functional  Acceptance  Tests in  accordance  with the  provisions of
Appendix K, testing the  compliance  of the AS Software with the AS Statement of
Work.  The Owner will  start the AS  Functional  Acceptance  Tests no later than
seven (7) days  after  installation  of such AS  Software  and  complete  the AS
Functional  Acceptance Tests no later than fourteen (14) days after installation
of such AS Software.

         (b) After such AS  Software  has  successfully  passed  the  Functional
Acceptance  Tests,  the Owner  will  commence  the AS Final  Acceptance  Test in
accordance  with the  provisions  of  Appendix  K. The  duration of the AS Final
Acceptance Test shall be thirty (30) days after successful  completion of the AS
Functional Acceptance Test.

         (c) If the Owner fails to conduct  either the AS Functional  Acceptance
Tests or the  Final  Acceptance  Test  within  the  time  periods  set  forth in
subsections  9.7(a) and 9.7(b),  the AS Software shall be deemed to have met the
Acceptance  Test  criteria on the last day of the time period  allotted  for the
applicable AS Acceptance Test.

         (d) The costs and expenses of the AS Acceptance  Tests will be borne by
the Owner. Upon request of the Owner, the Vendor will provide reasonable support
to the  Owner  during  the AS  Functional  Acceptance  Tests  and  the AS  Final
Acceptance Tests.

         (e) If the AS Acceptance Tests show that the AS Software  complies with
the AS  Statement  of Work,  such AS  Software  will be accepted by the Owner by
confirming the results in a written report.

         (f) If any AS Acceptance  Test is not satisfied,  the Owner will (i) in
writing,  notify the Vendor of such  failure,  and (ii) the Vendor will promptly
correct whatever  Defects or Deficiencies  caused such AS Acceptance Test not to
be satisfied. After such correction, the Vendor must (i) repeat at its sole cost
and expense the failed AS Acceptance Tests and as many other AS Acceptance Tests
as are  necessary  to ensure in the  reasonable  opinion  of the Owner that such
correction  made by the Vendor would not have affected the outcome of such other
AS Acceptance Tests, and (ii) in writing, notify the Owner as to what correction
was made and what AS Acceptance  Tests were  repeated.  Nothing stated herein to
the  contrary  will in any way limit the  Owner's  right to  liquidated  damages
pursuant to subsection  15.8 or other  remedies under this Contract in the event
the Vendor fails to deliver AS Products in accordance  with the  requirements of
Appendix G on the dates originally scheduled for such deliveries.

         (g) Minor Defects and shortcomings not affecting the operational use of
any part of the AS Software  shall not give rise to  withholding  the acceptance
provided that the Vendor  undertakes to remedy such Defects and  shortcomings as
soon as reasonably possible, pursuant to the procedures described in Appendix K.

         9.8 Actiview Acceptance Testing and Acceptance.  (a) After installation
of  Actiview  Software  as set forth in  Appendix  S, the Owner  will  carry out
Actiview  Functional  Acceptance  Tests in  accordance  with the  provisions  of
Appendix S, testing the  compliance  of the Actiview  Software with the Actiview
Statement of Work. The Owner will start the Actiview Functional Acceptance Tests
no later than thirty (30) days after  installation of such Actiview Software and
complete the Actiview Functional  Acceptance Tests no later than sixty (60) days
after installation of such Actiview Software.

         (b) After the Actiview  Software has  successfully  passed the Actiview
Functional  Acceptance  Tests,  the  Owner  will  commence  the  Actiview  Final
Acceptance  Test in accordance  with the  provisions of Appendix S. The Actiview
Final Acceptance Test shall be thirty (30) days after  successful  completion of
the Actiview Functional Acceptance Test.

         (c) If the  Owner  fails to  conduct  either  the  Actiview  Functional
Acceptance  Tests or the Actiview Final Acceptance Tests within the time periods
set forth in subsections 9.8(a) and 9.8(b), the Actiview Software will be deemed
to have met the Actiview  Acceptance  Test  criteria on the last day of the time
period  allotted for the  applicable  Actiview  Acceptance  Test unless any such
delay is caused by or due to an act or omission of the Vendor and/or a Defect in
the Actiview Software.

         (d) The Owner will be  responsible  for the costs and  expenses  of the
Actiview  Acceptance  Tests. The Vendor will provide the support services to the
Owner set forth in the Actiview Statement of Work.

         (e) If the  Actiview  Acceptance  Tests  show that any of the  Actiview
Software  complies with the Actiview  Statement of Work, such Actiview  Software
will be accepted by the Owner by confirming the results in a written report.

         (f) If any Actiview  Acceptance  Test is not satisfied,  the Owner will
(i) in  writing,  notify the Vendor of such  failure,  and (ii) the Vendor  will
promptly  correct   whatever  Defects  or  Deficiencies   caused  such  Actiview
Acceptance Test not to be satisfied.  After such correction, the Vendor must (i)
repeat at its sole cost and expense the failed Actiview  Acceptance Tests and as
many  other  Actiview  Acceptance  Tests  as  are  necessary  to  ensure  in the
reasonable  opinion of the Owner that such  correction  made by the Vendor would
not have affected the outcome of such other Actiview  Acceptance Tests, and (ii)
in writing,  notify the Owner as to what  correction  was made and what Actiview
Acceptance  Tests were  repeated.  Nothing stated herein to the contrary will in
any way limit the Owner's  right to  liquidated  damages  pursuant to subsection
15.10 or other  remedies  under the  Contract  in the event the Vendor  fails to
deliver  Actiview  Products in accordance with the requirements of Appendix U on
the dates originally scheduled for such deliveries.

         (g) Minor Defects and shortcomings not affecting the operational use of
any part of the  Actiview  Software  shall  not  give  rise to  withholding  the
acceptance  provided  that the Vendor  undertakes  to remedy  such  Defects  and
shortcomings  as  soon  as  reasonably  possible,  pursuant  to  the  procedures
described in Appendix S.


         SECTION 10  DISCONTINUED PRODUCTS

         10.1 Notice of  Discontinuation.  During the Term of this  Contract the
Vendor agrees to provide the Owner, or the respective Affiliates as the case may
be, except under  extraordinary  circumstances not less than one (1) year notice
before the Vendor discontinues accepting orders for a PCS Product ("Discontinued
Products") sold under this Contract.  Where the Vendor offers a product for sale
that is equivalent in form, fit and function in accordance  with and pursuant to
the  Specifications,  the  notification  period may vary but in no event will be
less  than  the  applicable   notice  period  set  forth  in  subsection   2.17.
Notwithstanding the foregoing,  the Vendor will not discontinue accepting orders
for any PCS Product applicable to or otherwise used in the System or any portion
thereof  until and unless the Vendor and the Owner have  agreed  upon a mutually
acceptable  transition  plan  that  takes  into  account  the  Owner's  and  its
Affiliates' existing investment in the Item scheduled for discontinuance subject
to the  minimum  terms and  conditions  set forth in  subsections  10.2 and 10.3
below.  The Parties'  failure to reach agreement  within sixty (60) days or such
other  reasonable time as they may mutually  establish will, upon the request of
either Party, be referred for resolution pursuant to Section 23. In the event of
the foregoing, the Vendor must continue to furnish PCS Products fully compatible
with the System  Elements  within the System at such time during the Term of the
Contract;  provided that nothing  herein will bar the Vendor from  discontinuing
individual  Items of PCS Products as provided in and pursuant to this subsection
10.1.

         10.2  Discontinuation  During Warranty Period.  If, during the Warranty
Period applicable to the relevant  Discontinued  Product pursuant to Section 17,
the Vendor does not make such Discontinued  Products available to the Owner, the
price of any Products provided as a replacement for the Discontinued  Product by
the Vendor and required to be purchased by the Owner during such Warranty Period
to replace  existing  Discontinued  Products  delivered to the Owner in order to
maintain performance and functionality equivalent to that previously provided by
the Discontinued Products will be discounted by an amount equal to fifty percent
(50%) of the price previously paid for such Discontinued Products.

         10.3  Discontinuation  After  Warranty  Period.  In the event  that the
Vendor discontinues the manufacture of a Product following the expiration of the
applicable  Warranty  Period and the Owner is  required  to replace an  existing
Discontinued  Product  with a new Product in order to maintain  performance  and
functionality,  the  Owner  will  receive  a credit  in an  amount  equal to the
percentage  set forth  below  multiplied  by the  purchase  price  paid for such
original Product, which credit will be applied against the Vendor's then-current
list price for a replacement for such  Discontinued  Product;  provided that the
credit will not exceed the Vendor's  then-current best list price (as determined
by the  Customer  Price  Guide)  for such  replacement  Product  subject  to the
discounts  available to the Owner  pursuant to Section 26 and the other terms of
this Contract:

        (i)  up to and including one year following expiration of the
                applicable Warranty Period:  40%;

        (ii) more than one year and up to and including two years following
                expiration of the applicable Warranty Period:  30%; and

        (iii)more than two years and up to and including three years following
                expiration of the applicable Warranty Period:  20%.


                  SECTION 11 SOFTWARE; CONFIDENTIAL INFORMATION

         11.1  RTU   License.   The  Owner  is  hereby   granted  a   perpetual,
non-exclusive,  non-transferable  (except as set forth in  subsections  11.4 and
27.4),  fully paid-up,  multi-site  (capability to have deployed Software in any
number of sites)  right to use  license for the  Software  ("RTU  License"),  to
operate the Products provided in each of the PCS Systems and/or PCS Sub-Systems,
as the case may be, and the System as a whole, subject to payment of any license
fees in accordance with the terms of this Contract. Except as otherwise provided
herein, the Owner is granted no title or ownership rights to the Software.  Such
rights  will  remain  with the  Vendor,  its  Subcontractors  or  suppliers,  as
appropriate.  The RTU License granted hereunder  includes and is deemed to cover
any  Affiliate  of the Owner to the extent  such  Affiliate  is (i)  developing,
constructing and/or operating a PCS system and (ii) seeking to access and/or use
the Products and Services available on or as a part of the Owner's System.

         11.2  Owner's Obligations.  The Owner agrees that the Software, whether
or not modified, will be treated as proprietary to the Vendor, its Subcontrac-
tors or its suppliers, as appropriate and the Owner will:

         (a) Utilize the Software  solely in conjunction  with the System and/or
any PCS System or any PCS Sub-System; provided that the Vendor acknowledges that
the Software will be integrated  across  interfaces with systems,  equipment and
software  provided by other suppliers and customers  including,  but not limited
to, the Other Vendors;

         (b) Ensure that all copies of the Software will, upon any  reproduction
by the Owner  authorized  by the Vendor  and  whether or not in the same form or
format as such  Software,  contain  the same  proprietary,  confidentiality  and
copyright  notices or legends  which  appear on the Software  provided  pursuant
hereto; and

         (c)  Hold  secret  and  not  disclose  the  Software  (or,  subject  to
subsection 27.19,  interfaces to or with such Software) to any person, except to
(i) such of its employees,  contractors,  agents or Affiliates that are involved
in the  operation or  management  of the System and/or any PCS System or any PCS
Sub-System  and need to have  access  thereto  to fulfill  their  duties in such
capacity,  or (ii)  other  Persons  who  need to use  such  Software  to  permit
integration of the System and/or any PCS System and/or any PCS  Sub-System  with
systems and software of other suppliers and customers including, but not limited
to, the Other  Vendors;  provided  that such  Persons  agree,  or are  otherwise
obligated, to hold secret and not disclose the Software to the same extent as if
they were subject to this Contract.

         (d)  When and if the  Owner  determines  that it no  longer  needs  the
Software or if the Owner's  license is  canceled or  terminated  pursuant to the
terms of this  Contract,  return  all copies of such  Software  to the Vendor or
follow reasonable written  disposition  instructions  provided by the Vendor. If
the Vendor  authorizes  disposition  by erasure or  destruction,  the Owner will
remove from the medium on which Software resides all electronic  evidence of the
Software,  both original and derived,  in such manner that  prevents  subsequent
recovery of such original or derived Software.

         11.3  Backwards  Compatibility.  (a)  In  addition  to  the  warranties
contained in Section 17 of this  Contract,  the Vendor  represents  and warrants
that each  Software  Revision  Level  during the Term of this  Contract  will be
Backwards  Compatible  with all existing  in-service  Equipment  provided by the
Vendor and the immediately  preceding  Software  Revision Level of such Software
made available to Customers by the Vendor.

         (b) In the event  that  Software  supplied  by the Vendor at any System
Element Site at any time does not provide Backwards Compatibility as required by
this subsection 11.3, then the Vendor will provide, without charge to the Owner,
the most current  Software  Updates of the Software to each such System  Element
Location, and otherwise take such steps as may be necessary to achieve Backwards
Compatibility.

         11.4  Transfer  and  Relocation.  (a) Except as provided in  subsection
27.4,  where the Owner or any successor to the Owner's title in the Products (i)
elects to  transfer a Product to a third  party,  and where  such  Product  will
remain in place and  operational for the purpose of continuing to provide PCS in
the  franchise  area in which  such  Product  is  installed,  or (ii)  elects to
transfer Products to an Affiliate for reuse within the United States,  the Owner
may transfer its RTU License for the Software  furnished under this Contract for
use  with  such  Product,   without  the  payment  of  any  additional  Software
right-to-use fees by the transferee, but only under the following conditions:

                  (A)      The  right to use such  Software  may be  transferred
                           only  together with the Products with which the Owner
                           has a right to use such  Software,  and such right to
                           use the Software  will  continue to be limited to use
                           with such Products;

                  (B)      Before any such  Software is  transferred,  the Owner
                           will  notify  the  Vendor  of such  transfer  and the
                           transferee  will have  agreed in  writing  (a copy of
                           which  will be  provided  to the  Vendor) to keep the
                           Software   in   confidence   and   to   corresponding
                           conditions  respecting possession and use of Software
                           as those imposed on the Owner in this Contract; and

                  (C)      The  transferee  will have the same right to Software
                           warranty and Software  maintenance  for such Software
                           as the transferor,  provided the transferee continues
                           to pay the fees,  including  recurring  fees, such as
                           Annual Release  Maintenance Fees, if any,  associated
                           with such Software warranty or maintenance.

         (b) Except as provided in subsection  11.4(a) or subsection  27.4,  and
except as may otherwise in this Contract be provided expressly, the Owner or any
successor to the Owner's  title in the  Products  will have no right to transfer
Software  furnished by the Vendor under this Contract without the consent of the
Vendor.  If the Owner or such successor  elects to transfer a Product  purchased
under this  Contract for which it does not under this Contract have the right to
transfer  related  Software,  the Vendor agrees that upon written request of the
transferee of such Product,  or of the Owner or such successor,  the Vendor will
not without  reasonable  cause fail to grant to the  transferee a license to use
such Software with the Products,  whether to be located within the United States
or elsewhere, upon payment of a relicensing fee to the Vendor in an amount equal
to fifty  percent (50%) of the license fee for the Software  originally  paid by
the Owner to the Vendor at the time of the  original  purchase  of the  Software
from the Vendor;  provided  that such  relicensing  fee will in no event  exceed
fifteen  percent (15%) of the price paid by the  transferee to the Owner for the
Product with respect to which such Software is used.

         11.5 Survival. The obligations of the Owner under the Software Licenses
will  survive  the  termination  of this  Contract,  regardless  of the cause of
termination.

         11.6  Access to Source  Codes.  The Vendor  grants the Owner a right to
access the Source Code and to modify the Software  (the "RTM  License")  for the
maintenance, enhancement and support of those Products purchased from the Vendor
and owned or operated by the Owner under the following  circumstances which will
be set forth in the Escrow Agreement:

         (a) If the Vendor becomes insolvent, makes a general assignment for the
benefit of creditors, files a voluntary petition in bankruptcy or an involuntary
petition in bankruptcy is filed against the Vendor which is not dismissed within
sixty (60) days,  or suffers or permits the  appointment  of a receiver  for its
business,  or its assets become subject to any proceeding  under a bankruptcy or
insolvency  law,  domestic or foreign,  or has liquidated  its business,  or the
Vendor,  or a business unit of the Vendor that is responsible for maintenance of
the Software,  ceases doing business without providing for a successor,  and the
Owner has reasonable  cause to believe that any such event will cause the Vendor
to be unable to meet its warranty service or support requirements hereunder; or

         (b) If it is determined,  pursuant to the dispute resolution mechanisms
set forth in  subsection  23.1,  that the Vendor,  its  assignee or designee has
failed,  or is unable,  to provide the warranty service or support of the System
and/or any PCS System and/or any PCS Sub-System contemplated by this Contract.

         11.7 Escrow Agreement.  The Vendor agrees,  at the Owner's request,  to
become party to a Source Code escrow  agreement (the "Escrow  Agreement")  which
will  allow the Owner to obtain  access to the  applicable  Source  Codes in the
circumstances set forth in subsection 11.6 and such Escrow Agreement.  The Owner
will  pay all  costs,  including  the  Vendor's  reasonable  costs  incurred  in

Escrow Agreement. The Vendor represents, warrants and agrees that (i) the Source
Codes  delivered  into  escrow in  accordance  with the  Escrow  Agreement  will
comprise the full Source Code  language  statement  of the Software as used,  or
required to be used,  by the Vendor to maintain or modify the System  and/or any
PCS System  and/or any PCS  Sub-System  without the help of any other  Person or
reference  to any other  material,  (ii) such  Source  Codes  will  include  all
versions thereof from the date of initial creation,  and (iii) such Source Codes
must be kept up to date,  including  all updates  needed to maintain  compliance
with the Specifications and the System Standards.  In addition, all parts of the
Source  Codes  from  the  date of  creation  thereof,  and all  updates  thereto
(including,  without limitation, those that are necessary to maintain compliance
with the  Specifications)  must be delivered into escrow in accordance  with the
Escrow Agreement; provided that the Vendor will not be required to update and/or
deliver  into  escrow  any  updates  of any Owner  Software  modifications  made
pursuant to subsections 12.5, 12.6 or 12.7.

         11.8 Software Maintenance.  The Vendor represents and warrants that the
Software  delivered  to  the  escrow  agent  pursuant  to  subsection  11.7  for
redelivery  to the Owner  pursuant  to the  Escrow  Agreement  will be in a form
suitable  for  reproduction  by the Owner and will  include the full Source Code
language  statement  of the Software as used by the Vendor  sufficient  to allow
maintenance and modification.

         11.9  Custom Development.

                  11.9.1 Request for Custom Material. (a) From time to time, the
Owner may have requirements for custom Software (including,  but not limited to,
development  of  identified  features or  modifications  to Software or Software
Enhancements) or custom development of Equipment (including, but not limited to,
development of identified  features or  modifications  to Equipment or Equipment
Enhancements)  to be provided by the Vendor  under this  Contract  (the  "Custom
Material").  If the  Owner  has a  requirement  for  Custom  Material  that is a
specific  enhancement or  modification  of a previously  licensed  feature or of
previously purchased Products,  the Owner will identify to the Vendor in writing
a summary of any such proposed development of Custom Material. Such summary will
provide a description of any proposed Custom  Material  sufficient to enable the
Vendor to determine  the general  demand for, and its plans,  if any, to develop
the same or similar  Products.  The Vendor will respond to such  summary  within
thirty (30) days after  receipt  thereof  and  indicate if it has the ability to
fulfill  a  subsequent  Request  for  Proposal  ("RFP")  from the Owner for such
development of Custom Material. The Owner acknowledges that the Vendor will have
no obligation to develop any proprietary materials for Owner.

         (b) If the Vendor  decides that it does not have the technical  ability
or  the  capacity  to  fulfill  a  subsequent  RFP  for  such  Custom   Material
development,  the Vendor's  response  pursuant to subsection  11.9.1(a) will (i)
provide the Owner an  explanation of why it cannot fulfill such RFP and (ii) use
reasonable  diligence to work with the Owner to identify an  alternative  source
for such development  reasonably acceptable to the Owner. In determining whether
the Vendor has the  technical  ability or the  capacity to fulfill the RFP,  the
Vendor may  consider  factors  including,  but not limited to, (1) the  Vendor's
likelihood of recovering  its costs for  performing  such  development,  (2) the
impact of such  development on the Vendor's  actual  outstanding  commitments to
perform work for other Customers and to pursue strategic development activities;
and (3)  whether the Vendor can perform  the work  utilizing  existing  software
development staff without stopping work underway.

         (c) If the  Vendor  fails to agree to a  request  for  Custom  Material
development  pursuant to the terms of this  subsection 11.9 then the matter may,
at the Owner's option, be referred to dispute resolution pursuant to Section 23.

                  11.9.2 Vendor Response. After reviewing an RFP issued for such
Custom  Material,  the Vendor will respond to the Owner within thirty (30) days,
unless  otherwise  agreed by the Parties,  stating the terms and conditions upon
which the Vendor would be willing to undertake such development,  including, but
not limited to, a listing of specifications, custom development charges, planned
license fees and a proposed delivery schedule.

                  11.9.3 Ownership of Intellectual Property. The Vendor will own
all forms of  intellectual  property  rights  (including,  but not  limited  to,
patent,  trade secret,  copyright and mask rights)  pertaining to Products,  and
will have the right to file for or otherwise secure and protect such rights. The
foregoing  notwithstanding,  the Parties  understand and agree that from time to
time the Owner may devise,  develop or otherwise  create ideas or other concepts
for  services or new  products  which are  patentable  or  otherwise  capable of
receiving  protection from  duplication.  In such event, the Owner will have the
right to patent or otherwise  protect such ideas or concepts for its own use and
benefit.


                           SECTION 12 SOFTWARE CHANGES

         12.1 Annual  Release  Maintenance  Fees.  So long as the Owner pays the

                          SECTION 13 EQUIPMENT CHANGES

         13.1 Equipment Upgrades. (a) Equipment Upgrades will be provided to the
Owner by the Vendor at no charge to the Owner as provided in subsection  13.1(b)
below.  Equipment  Enhancements  must be provided to the Owner by the Vendor, if
requested by the Owner,  and the Owner is obligated to make payment  therefor in
an amount that is no higher  than that  payable by any  Customer  other than the
Owner, which amount of payment will be adjusted as set forth in subsections 6.2,
7.2 and 27.16 Section 26. If the Vendor at any time issues an Equipment  Upgrade
which is combined with any Equipment Enhancement  (collectively,  the "Equipment
Combined  Release") to such Equipment,  the Equipment  Combined  Release will be
provided at no charge to the Owner  unless and until the Owner elects to use any
of the  feature  enhancement  or  enhancements  included  within  the  Equipment
Combined Release and has accepted such Equipment Combined Release.

         (b) (i) After a PCS  Product  has been  shipped  to the  Owner,  if the
Vendor issues an Equipment  Upgrade ("Class A change") or Equipment  Enhancement
("Class  B  change"),  or  where a  modification  to  correct  an error in field
documentation is to be introduced,  the Vendor will promptly notify the Owner of
such change  through the Vendor's  design  change  management  system or another
Vendor notification procedure. Each change notification, whether or not it bears
a  restrictive  legend,  will be subject to subsection  27.19,  except that such
information  may be  reproduced  by the Owner for the  Owner's  use as  required
within the System.  If the Vendor has  engineered,  furnished,  and  installed a
Product which is subject to an Equipment Upgrade, the Vendor will implement such
change,  at its sole cost and expense,  if it is announced  within  fifteen (15)
years from the date of shipment of that Product,  by, at its option  (subject to
the  reasonable  review and  acceptance  of the Owner at such times as the Owner
reasonably determines that it needs to review such Vendor decision),  either (A)
modifying the Product at the Owner's  site;  (B) modifying the Product which the
Owner has  returned to the Vendor in  accordance  with the  Vendor's  reasonable
instructions  pursuant to and in accordance with the terms of this Contract;  or
(C)  replacing the Product  requiring the change with a replacement  Product for
which such change has already been implemented. If the Vendor has not engineered
the  original  Product  application  and  accordingly  office  records  are  not
available to the Vendor,  the Vendor will provide the generic change information
and associated parts for the Owner's use in implementing such change.

                    (ii) In any of the instances  described in clause (i) above,
                         if the  Vendor  and the Owner  agree  that a Product or
                         part   thereof   subject  to  such  change  is  readily
                         returnable,  the Owner, at its expense, will remove and
                         return such Product or part to the Vendor's  designated
                         facility  within the United  States and the Vendor,  at
                         its  sole  expense,  will  implement  such  change  (or
                         replace it with a Product or part for which such change
                         has  already  been  implemented)  at its  facility  and
                         return such changed (or replacement) Product or part at
                         its sole cost and  expense  to the  Owner's  designated
                         location   within   the   United   States.   Any   such
                         reinstallation  will be  performed  by the Owner at its
                         sole expense.  At any such time that the Owner's spares
                         or plug-in  stocks are not  available  to  implement  a
                         rotational program for an Equipment Upgrade, the Vendor
                         will   provide  a  seed  stock,   where   feasible  and
                         necessary.

                    (iii)If the  Owner  does not make or  permit  the  Vendor to
                         make an  Equipment  Upgrade as stated  above within one
                         (1) year from the date of change  notification  or such
                         other  period  as  the  Vendor  may  agree,  subsequent
                         changes,   repairs  or  replacements  affected  by  the
                         failure  to  make  such  change  may,  at the  Vendor's
                         option,  be invoiced  to the Owner  whether or not such
                         subsequent  change,  repair or  replacement  is covered
                         under the warranty  provided in this  Contract for such
                         Product. If requested by the Owner,  Equipment Upgrades
                         announced more than fifteen (15) years from the date of
                         shipment will be implemented at the Owner's expense.

                    (iv) If the Vendor issues an Equipment  Enhancement  after a
                         PCS Product has been  shipped to the Owner,  the Vendor
                         will promptly  notify the Owner of such change if it is
                         being offered to any of the Vendor's Customers.  Except
                         as  otherwise  set forth above in  subsection  13.1(a),
                         when  an  Equipment  Enhancement  is  requested  by the
                         Owner, the pricing set for such Equipment  Enhancements
                         will be at the Vendor's standard charges subject to the
                         applicable  discounts  set forth in this  Contract  and
                         Section 26.

                    (v)  All change  notifications  for  Equipment  Upgrades and
                         Equipment  Enhancements  provided  by the Vendor to the
                         Owner  pursuant  to the  terms  of this  Contract  must
                         contain  the  following  information:  (i)  a  detailed
                         description  of the  change;  (ii) the  reason  for the
                         change;  (iii) the  effective  date of the change;  and
                         (iv) the  implementation  schedule for such change,  if
                         appropriate.

         13.2  Notice.  The Vendor will give the Owner not less than ninety (90)
days prior written notice of the  introduction  of any Equipment  Enhancement or
any Equipment Combined Release. In addition, in February and August of each year
during the Term of this  Contract,  the  Vendor  will  provide  the Owner with a
forecast of future Equipment Enhancements to the Equipment or Equipment Combined
Releases then currently being developed by or on behalf of the Vendor.

         13.3 Installation, Testing and Acceptance. The Installation and testing
of the Equipment by the Vendor and the  acceptance  thereof by the Owner must be
performed in  accordance  with Exhibit B3 pursuant to the Project  Milestones in
Exhibit A.

         13.4  Equipment  Fixes.  In the event  that any  Equipment  Upgrade  or
Equipment  Enhancement  supplied by the Vendor  during the Term of this Contract
has the effect of  preventing  the System  and/or any PCS System  and/or any PCS
Sub-System  or any part thereof from  satisfying,  or  performing  in accordance
with, the  Specifications,  the System  Standards  and/or Exhibit F or otherwise
adversely affects the functionality, interoperability or features of the System,
any such PCS System or PCS Sub-System or any part thereof,  then the Vendor will

                                    (i) the Vendor will be given prompt  written
                           notice  of all  claims  of any such  infringement  or
                           violation  and of any  suits  or  claims  brought  or
                           threatened  against  the Owner or the Vendor of which
                           the Owner has actual knowledge;

                                    (ii) the Vendor will be given full authority
                           to assume control of the defense (including  appeals)
                           thereof  through its own counsel at its sole  expense
                           and will have the sole  right to settle  any suits or
                           claims  without  the  consent of the Owner;  provided
                           that  the  Vendor  will  have no  right  to  agree to
                           injunctive relief against the Owner; provided further
                           that the Vendor will notify the Owner of any proposed
                           settlement condition prior to the Vendor's acceptance
                           of such settlement; and

                                    (iii) the Owner  will  cooperate  fully with
                           the Vendor in the  defense of such suit or claims and
                           provide the Vendor,  at the  Vendor's  expense,  such
                           assistance  as the Vendor may  reasonably  require in
                           connection therewith.

         (b) The Vendor's  obligation under this subsection 14.2 will not extend
to alleged  infringements or violations that arise because the Products provided
by the Vendor are used in  combination  with other  products  furnished by third
parties and where any such combination was not installed, recommended, approved,
explicitly or by implication, by the Vendor.

         14.3 Vendor's Obligation to Cure. If in any such suit so defended,  all
or any part of the  Equipment,  Software,  the System,  any PCS System,  any PCS
Sub-System or any component  thereof is held to  constitute an  infringement  or
violation of  Intellectual  Property  Rights and its use is  enjoined,  or if in
respect of any claim of  infringement or violation the Vendor deems it advisable
to do so, the Vendor will at its sole cost,  expense and option take one or more
of the following actions:  (i) procure the right to continue the use of the same
without interruption for the Owner; (ii) subject to the terms of subsection 2.17
replace  the same  with  noninfringing  Equipment  or  Software  that  meets the
Specifications;  or (iii) modify said Equipment,  Software,  the System, any PCS
System,  any PCS Sub-System or any component  thereof so as to be noninfringing,
provided  that the  Equipment,  Software,  the System,  any PCS System,  any PCS
Sub-System or any component thereof as modified meets all of the Specifications.
In the event that the Vendor is not able to cure the  infringement  pursuant  to
clause (i), (ii) or (iii) in the immediately preceding sentence, the Vendor will
refund  to the  Owner  the  full  purchase  price  paid by the  Owner  for  such
infringing  Product or  feature,  and the Owner will be under no  obligation  to
return to the Vendor such infringing  Product or feature  regardless of whether,
or by what means,  the Owner, on its own or otherwise,  subsequently  cures such
infringement.

         14.4 Vendor's Obligations.  The Vendor's obligations under this Section
14 will not apply to any  infringement  or  violation of  Intellectual  Property
Rights to the extent caused by  modification  of the  Equipment,  Software,  the
System,  any PCS System,  any PCS  Sub-System  or any  component  thereof by the
Owner, or any  infringement  caused solely by the Owner's use and maintenance of
the Products other than in accordance with the  Specifications  and the purposes
contemplated  by this Contract,  except as expressly  authorized or permitted by
the Vendor.  The Owner will  indemnify the Vendor  against all  liabilities  and
costs,  including reasonable  attorneys' fees, for defense and settlement of any
and all claims  against the Vendor for  infringements  or violations  based upon
this subsection 14.4.

         14.5 License to Use Vendor Patents.  (a) The Vendor grants to the Owner
and its  Affiliates,  under  patents  which  the  Vendor  owns or has a right to
license ("Vendor Patents"), a worldwide, royalty-free, nonexclusive license (the
"Patent License") to use any Product furnished by the Vendor under this Contract
(including any combination of products and services, whether or not furnished at
the  same  time  or  as  part  of  a  larger   combination)   for  provision  of
telecommunications  services;  provided, however, that no rights are conveyed to
the Owner and its Affiliates  with respect to any invention which is directed to
(i) a combination  of a Product or Products  furnished with any other Item which
the Vendor does not furnish to the Owner under this  Contract  wholly or in part
for such use, or (ii) a method or process which is other than an inherent use of
the Products furnished. As used in this subsection 14.5, the term "inherent use"
means a use that can be  completely  performed  by a  Product  furnished  by the
Vendor (or a combination of Products furnished by the Vendor),  without the need
for any additional product, service,  development modification or programming by
the Owner and its Affiliates or by a third party.

         (b) The Owner and any  successor  to the Owner's  title in the Products
has the right  (subject to written  approval of the Vendor,  which approval will
not be unreasonably withheld), to assign the Patent Licenses to any other Person
who  acquires  legal title to the  Products  including,  but not limited to, any
Person or Persons  taking part in the  financing  of any part of the  Nationwide
Network,  provided  that  no  such  assignment  to  Persons  taking  part in the
financing of any part of the  Nationwide  Network  will be  permitted  except in
accordance  with the  provisions of subsection  27.4 of this  Contract.  Nothing
contained  in this  subsection  14.5 is  intended  to, and shall not,  limit any
rights or privileges  that the Owner has under this Contract or otherwise  under
Applicable Law.


                                SECTION 15 DELAY

         15.1 Liquidated  Damages.  The Parties agree that damages for delay are
difficult to calculate accurately and, therefore,  agree that liquidated damages
(the "Liquidated  Damages") will be paid for non-performance or late performance
of the Vendor's obligations under this Contract pursuant to the terms hereof.

         15.2  Interim  Delay.  (a) Failure of the Vendor to  complete  the Work
necessary to achieve each of the Project Milestones applicable to any PCS System
and/or any PCS  Sub-System,  as the case may be (other than  Milestone 3 (as set
forth on Exhibit  A1)), on or before the date  applicable to such  Milestone for
such PCS System or PCS  Sub-System,  as the case may be,  that is required to be
achieved by the Vendor prior to the Guaranteed  Substantial  Completion Date for
such PCS System or PCS Sub-System  (each an "Interim  Milestone") will result in
the Vendor  being  liable to pay to the Owner an amount  equal to  [__________];
provided that no such Interim Delay Penalty will be due if the delay is directly
and expressly  attributable  solely to (i) an event constituting a Force Majeure
pursuant to the terms of this  Contract or (ii) an act or omission of the Owner.
Interim Delay  Penalties  accrued  pursuant to this  subsection  15.2(a) will be
offset  against  the  payment  to be  made  by  the  Owner  to the  Vendor  upon
Substantial Completion of the PCS System or PCS Sub-System to which such interim
delay relates. The Interim Delay Penalty applicable to Milestone 4 (as set forth
on Exhibit A1) will be [__________]. This subsection 15.2 will not be applicable
to  Milestone  3 (as set forth on  Exhibit  A1) for either the System or any PCS
System or any PCS Sub-System.

         (b) To the extent  that the Vendor is  responsible  for  Interim  Delay
Penalties pursuant to subsection 15.2(a) such penalties will be credited back to
the Vendor by the Owner to the extent that (i) the Vendor successfully  achieves
the  Interim  Milestone  subject to delay  within  thirty  (30) days of the date
scheduled  therefore  pursuant  to the terms  hereof and Exhibit A and (ii) such
interim delay does not otherwise materially adversely affect the Owner, such PCS
System or PCS Sub-System  and/or the System as a whole.  Any such  reimbursement
will be  credited  back to the  Vendor  such  that  the  Interim  Delay  Penalty
otherwise  offset  against  the  relevant  Substantial   Completion  payment  in
accordance with subsection  15.2(a) above will be added back to such Substantial
Completion payment to be made to the Vendor by the Owner.

         15.3 Completion  Delay. (a) For each day that any PCS System and/or any
PCS Sub-System, as the case may be, fails to [__________],  the Vendor will pay,
subject to the  limitations  otherwise  set forth in this  subsection  15.3,  an
amount equal to [_____________] percent of the Product Contract Price applicable
to such PCS System or PCS  Sub-System,  as the case may be,  [_________].  In no
event will the Late  Completion  Payments  payable by the Vendor with respect to
any PCS System or such PCS Sub-System, as the case may be, exceed [___________].

         (b)  If  any  PCS  System  or  any  PCS  Sub-System  does  not  achieve
Substantial  Completion by the Guaranteed Substantial Completion Date applicable
thereto but the Owner  nonetheless  chooses (in its sole discretion) to commence
In Revenue  Service in such  incomplete PCS System or incomplete PCS Sub-System,
as the case may be (such action in no way constituting  the Owner's  acceptance,
express or implied,  of the System or such PCS System or such PCS  Sub-System or
any part  thereof),  then the Vendor will be required to pay, on a daily  basis,
only  that  percentage  of the  daily  Late  Completion  Payment  equal  to that
percentage of the geographic area to be otherwise  covered by such PCS System or
PCS Sub-System,  as the case may be, not otherwise  placed In Revenue Service by
the Owner.

         (c) In the event of a change in the Product  Contract Price pursuant to
subsections  6.2,  7.2 or 27.16 or Section  26 during the Term of this  Contract
from the amount  originally set forth in this Contract pursuant to Section 6 the
per diem amount of Late Completion Payments set forth above will be increased or
decreased, as appropriate, by an amount equal to the increase or decrease in the
Owner's per diem interest  payment  obligation  resulting from any change in the
amount of debt incurred or to be incurred by the Owner related to such change in
the Product Contract Price.

         (d) Late Completion  Payments,  including any portions of such payments
payable in accordance with paragraphs (a) and (b) above,  will be accrued during
the  Completion  Cure Period and offset  against  payments  otherwise due to the
Vendor upon the achievement of Substantial  Completion  pursuant to the terms of
subsection  6.3. If the Vendor fails to achieve  Substantial  Completion  within
sixty (60) days of the  Guaranteed  Substantial  Completion  Date for any reason
other than primarily because of (i) a Force Majeure event pursuant to Section 16
or (ii) the direct and  explicit  act or omission  of the Owner,  then the Owner
will have the option to terminate  this  Contract with respect to the PCS System
and/or  the PCS  Sub-System,  as the case  may be,  affected  by any such  delay
without any penalty or payment obligation (other than payment  obligations under
this Contract outstanding as of the date of any such termination;  provided that
any such  amounts  payable by the Owner will not include any amounts  that would
have been  payable  to the  Vendor  only upon  Substantial  Completion  or Final
Acceptance);  provided  further  that in the event the  Vendor  fails to achieve
Substantial  Completion  within such sixty (60) day period in any combination of
two (2) PCS Systems  and/or PCS  Sub-Systems  within the Initial System over any
period of time  (regardless of whether such events are concurrent or whether the
first such event was subsequently  cured) the Owner will have the right, but not
the obligation, to terminate this Contract in its entirety.

         15.4  SCP/HLR  Delay.  (a) Failure of the Vendor to  properly  deliver,
install and test any of the SCP/HLR Products at the then existing HLR Designated
Switch Sites in accordance  with the SCP/HLR  Specifications  and the milestones
set forth therein  applicable to SCP/HLR  Products by the HLR  Completion  Dates
will  result in the  Vendor  being  liable to pay to the  Owner  contract  cover
damages (the  "Contract  Cover  Damages")  equal to any and all  reasonable  and
actual  increased costs and expenses  including,  but not limited to,  increased
costs and expenses  associated  with  network  modifications,  extra  equipment,
software or training or re-engineering incurred by the Owner due to the Vendor's
failure to deliver,  install and test the SCP/HLR Products by the HLR Completion
Dates in accordance with SCP/HLR Specifications and the HLR Statement of Work.

         15.5 AM/HLR Interim  Solution.  In order to meet the Owner's  projected
service date the Vendor will provide to the Owner,  [_____________],  and at the
Owner's then existing HLR Designated  Switch Sites,  AM/HLRs  pursuant to and in
accordance  with the AM/HLR  Specifications  and the HLR Statement of Work as an
interim  solution so that the Nationwide  Network may operate in accordance with
the  Specifications;  provided  that the Vendor  will  continue  to use its best
efforts,  [______________] (but with all reasonable cooperation from the Owner),
to replace such interim AM/HLR solution with a  comprehensive  SCP/HLR system in
accordance with the SCP/HLR Specifications and the HLR Statement of Work.

         15.6 AM/HLR Redeployment.  After acceptance of the SCP/HLRs,  the Owner
will, at the Owner's sole  discretion,  have the Vendor  redeploy the AM/HLRs as
Access  Managers to other sites within the System at the Vendor's  sole cost and
expense  for any and all  costs  associated  with such  redeployment,  including
removal,  transportation,  and delivery but not installation or the cost of such
Access  Manager;  provided  that if the  Access  Manager is not moved to another
location but  redeployed  in the same  location in a separate  function or for a
separate  MSC, the Owner will only be liable for the cost of the Access  Manager
and the Vendor will be responsible  for all other costs.  All payments,  if any,
for  redeployed  AM/HLRs  will be  made by the  Owner  pursuant  to  subsections
6.3(a)-(d);  provided that in the event that any such  redeployment  is to a PCS
System which has already achieved Substantial  Completion then the payment terms
of subsection 6.3.1 will apply.

         15.7 SCP/HLR Delay Termination. If after thirty (30) days after the HLR
Completion Dates the Vendor is still unable to satisfactorily complete the Final
Acceptance  Tests  applicable to the SCP/HLRs and/or any of the SCP/HLR Products
to be delivered in accordance  with the terms of this Contract  (including,  but
not limited to, the  SCP/HLR  Specifications)  the Owner will have the right (in
addition to any rights under subsection 15.4 above), but not the obligation,  to
terminate the Contract  only with respect to the SCP/HLR  Products and will have
the right to seek from the Vendor  reimbursement  for any of its  reasonable and
actual increased costs associated with acquiring reasonable  replacement SCP/HLR
Products  from a  third-party  supplier.  The remedies set forth in  subsections
15.4, 15.5 and 15.7 will be the Owner's sole and exclusive remedies in the event
the Owner chooses to terminate the delivery of SCP/HLR Products  pursuant to the
terms of this subsection 15.7.

         15.8 AS Software  Delay.  With respect to the AS Products and Services,
in the event the Vendor fails to deliver any such AS Statement of Work compliant
AS Products  and/or AS Services within seven (7) days (except as provided below,
the "AS Delay Grace Period") of the  applicable  dates for delivery set forth in
Appendix G, the Vendor will (to the extent the Owner will not have cancelled the
applicable  order therefor  pursuant to the terms of the Contract) credit to the
Owner (in the form of purchase  credits for any Vendor Products  including,  but
not limited to, AS Products) as liquidated damages for such late performance for
each of the first thirty (30) days beyond such AS Delay Grace Period,  an amount
equal to [____________]  percent per day (for such [________] day period) of the
total price of such  undelivered or  unsatisfactory  AS Products or AS Services;
provided that upon the timely AS Functional  Acceptance (on the dates originally
scheduled for such AS Functional  Acceptance) of any such AS Products  and/or AS
Services,  any delay penalties accrued therefor shall be forgiven;  and provided
further  for AS Software  "release  0.1" (as defined in Appendix G) the AS Delay
Grace  Period  will be  [________]  days  from the  delivery  dates set forth in
Appendix G for the delivery of such AS Software release 0.1.

         15.9 OTAF and/or Actiview Delay Termination.  If after thirty (30) days
after the OTAF  Completion  Dates the Vendor is still  unable to  satisfactorily
complete the OTAF Final  Acceptance Tests and/or any of the OTAF Products and/or
Services  to be  delivered  in  accordance  with  the  terms  of  this  Contract
(including,  but not limited to, the OTAF Statement of Work) the Owner will have
the right,  but not the obligation,  to terminate the Contract only with respect
to the OTAF  Products  and/or  Services and will have the right to seek from the
Vendor  reimbursement  for any of its  reasonable  and  actual  increased  costs
associated with acquiring  reasonable  replacement OTAF Products and/or Services
from a  third-party  supplier.  If after  thirty  (30) days  after the  Actiview
Completion  Dates the  Vendor is still  unable to  satisfactorily  complete  the
Actiview  Final  Acceptance  Tests  and/or any of the Actiview  Products  and/or
Services  to be  delivered  in  accordance  with  the  terms  of  this  Contract
(including,  but not limited to, the Actiview  Statement of Work) the Owner will
have the right,  but not the  obligation,  to terminate  the Contract  only with
respect to the Actiview Products and/or Services and will have the right to seek
from the Vendor  reimbursement  for any of its reasonable  and actual  increased
costs associated with acquiring reasonable  replacement Actiview Products and/or
Services from a  third-party  supplier.  Pursuant to and in accordance  with the
Actiview  Statement  of Work,  the  Owner  will be  responsible  for the  timely
furnishing of the Actiview  operations  environment,  which  includes  delivery,
installation  and testing of third  party  equipment  and third  party  software
applicable and necessary for the operation of the Actiview Software. The Parties
understand  and agree that the dates set forth in  Section 12 of  Appendix M for
the  delivery of SCP/OTAF  Products  and  Services  are subject to  modification
pursuant  to the mutual  good faith  agreement  between the Parties on or before
October 14, 1996; provided,  that, the Vendor agrees that the delivery dates for
SCP/OTAF  Products  and  Services  will in no event be  modified to be more than
forty-five  (45) days beyond the dates for such  deliveries set forth in Section
12 of Appendix M as of the Effective Date.

         15.10  OTAF  and/or  Actiview  Delay.  (a)  (i)  With  respect  to  the
SPARC/OTAF  Products (other than any OTAF Maintenance and Instruction Manuals or
OTAF Operating Manuals) and SPARC/OTAF  Services,  in the event the Vendor fails
to deliver any such OTAF Statement of Work compliant  SPARC/OTAF Products and/or
Services within seven (7) days (the "OTAF Delay Grace Period") of the applicable
dates for delivery set forth in the OTAF  Statement of Work, the Vendor will (to
the extent the Owner  will not have  cancelled  the  applicable  order  therefor
pursuant  to the  terms of the  Contract)  credit  to the  Owner (in the form of
purchase  credits for any Vendor  Products  including,  but not limited to, OTAF
Products) as liquidated  damages for such late performance for each of the first
[________]  days  beyond  such OTAF  Delay  Grace  Period,  an  amount  equal to
[__________]  percent  per day (for such  [_________]  day  period)  of the OTAF
Price;  provided that upon the timely  SPARC/OTAF Field Acceptance (on the dates
originally   scheduled  for  such  SPARC/OTAF  Field  Acceptance)  of  any  such
SPARC/OTAF  Products and/or  SPARC/OTAF  Services,  any delay penalties  accrued
therefor shall be forgiven.  (ii) With respect to the SCP/OTAF  Products  (other
than any OTAF Maintenance and Instruction Manuals or OTAF Operating Manuals) and
Services,  in the event the Vendor  fails to deliver any such OTAF  Statement of
Work  compliant   SCP/OTAF   Products  (other  than  any  OTAF  Maintenance  and
Instruction Manuals or OTAF Operating Manuals) or Services within seven (7) days
of the  applicable  dates for delivery set forth in the OTAF  Statement of Work,
the Vendor will (to the extent the Owner will not have  cancelled the applicable
order  therefor  pursuant to the terms of the Contract)  credit to the Owner (in
the form of purchase credits for any Vendor Products including,  but not limited
to, OTAF Products) as liquidated  damages for such late  performance for each of
the first  [_________] days beyond such OTAF Delay Grace Period, an amount equal
to  [___________]  percent per day (for such [_________] day period) of the OTAF
Price;  provided that upon the timely  SCP/OTAF  Field  Acceptance (on the dates
originally  scheduled for such SCP/OTAF  Field  Acceptance) of any such SCP/OTAF
Products and/or SCP/OTAF Services, any delay penalties accrued therefor shall be
forgiven.

                  Furthermore  and in  addition  to any and all  damages  and/or
remedies  available to the Owner  pursuant to this Section 15, with respect to a
delay in the Specification  compliant  availability and installation of SCP/OTAF
Products and Services in accordance with the dates and  requirements of the OTAF
Statement  of Work  that is in  excess of  thirty  (30)  days  beyond  the dates
originally  scheduled for any such SCP/OTAF  Products and Services  availability
and installation,  the Owner will be entitled to and the Vendor will provide for
the Owner's Nationwide Network,  SPARC/OTAF Products and Services that are equal
in features and  functionality to the SCP/OTAF  Products and Services that would
have been available and installed pursuant to the OTAF Statement of Work but for
such delay in the availability  and/or  installation of Specification  compliant
SCP/OTAF Products or Services.

         (b) With respect to the Actiview Products and Actiview Services, in the
event the Vendor fails to deliver any such Actiview  Statement of Work compliant
Actiview  Products  and/or  Services  within seven (7) days (the "Actiview Delay
Grace  Period") of the  applicable  dates for delivery set forth in the Actiview
Statement  of Work,  the  Vendor  will (to the  extent  the Owner  will not have
cancelled the applicable  order therefor  pursuant to the terms of the Contract)
credit to the Owner (in the form of  purchase  credits  for any Vendor  Products
including, but not limited to, Actiview Products) as liquidated damages for such
late  performance for each of the first [______] days beyond such Actiview Delay
Grace  Period,  an  amount  equal to  [__________]  percent  per day  (for  such
[________] day period) of the total price of such undelivered or  unsatisfactory
Actiview Products or Actiview  Services;  provided that upon the timely Actiview
Functional  Acceptance  (on the dates  originally  scheduled  for such  Actiview
Functional  Acceptance) of any such Actiview Products and Actiview Services, any
delay penalties accrued therefor shall be forgiven.


                            SECTION 16 FORCE MAJEURE

         16.1 Force  Majeure.  (a) Either  Party may make a claim for  excusable
failure  or delay  with  respect  to any  obligation  of such  Party  under this
Contract,  except any obligation to make payments when due. Excusable failure or
delay will be  allowed  only in the event of an event of Force  Majeure  that is
beyond  the  reasonable  control of the  affected  Person.  Notwithstanding  the
foregoing,  the Vendor will not be entitled to relief  under this  Section 16 to
the  extent  that any event  otherwise  constituting  an event of Force  Majeure
results from the negligence or fault of the Vendor or any Subcontractor, and the
Owner will not be  entitled  to relief  under this  Section 16 to the extent any
event  otherwise  constituting  an  event  of  Force  Majeure  results  from the
negligence or fault of the Owner.

         (b) The Party  claiming the benefit of excusable  delay  hereunder must
(i) promptly notify the other Party of the circumstances creating the failure or
delay and provide a statement  of the impact of such Party  failure or delay and
(ii) use  reasonable  efforts to avoid or remove such causes of  nonperformance,
excusable  failure or delay.  If an event of Force  Majeure  prevents the Vendor
from performing its obligations under this Contract for a period exceeding sixty
(60) days,  the Owner may,  upon prior written  notice to the Vendor,  terminate
this Contract.

         (c) The Party not  claiming the benefit of  excusable  delay  hereunder
will  likewise be excused from  performance  of its  obligations  hereunder on a
day-for-day basis to the extent such Party's obligations are affected due to the
other Party's delayed performance.

         (d) In the event of a Force Majeure which the Party claiming relief for
such event has used all best efforts to resolve in accordance  with the terms of
this Contract, upon the written request of either Party, the other Party will in
good faith negotiate  modifications,  to the extent reasonable and necessary, in
scheduling and performance criteria in order to reasonably address the impact of
such Force Majeure.

                              SECTION 17 WARRANTIES

         17.1 Product  Warranty.  (a) The Vendor  warrants that, for a period of
two (2) years from the date of Final  Acceptance  of any PCS  System  and/or PCS
Sub-System, as the case may be (the "Product Warranty Period"), all Products and
all of the Installation and the  Configuration  Engineering  thereof within such
PCS System and/or PCS Sub-System,  as the case may be, will  materially  conform
with and perform the functions set forth in the  Specifications and the relevant
performance criteria set forth in Exhibit D, to the extent applicable,  and will
be free from Defects and  Deficiencies  in material or workmanship  which impair
service to  subscribers,  System  performance,  billing,  administration  and/or
maintenance.  In the case of Software, the Product Warranty Period applicable to
any such Software will be automatically  extended upon, and  simultaneous  with,
any Software Upgrade issued pursuant to the terms of Section 12. The Vendor will
assign to the Owner all  outstanding  Subcontractor  warranties  attributable to
Non-Essential  Equipment  at  such  time  that  the  Vendor's  warranty  on such
Non-Essential Equipment pursuant to this subsection 17.1 expires pursuant to and
in  accordance  with the  Product  Warranty  Period  applicable  to such Item of
Non-Essential  Equipment.  The Warranty Period for a PCS Product or part thereof
repaired or provided as a  replacement  under this  Product  warranty is six (6)
months or the unexpired term of the new Product  Warranty  Period  applicable to
the repaired or replaced PCS Product or part, whichever is longer.

         (b) To the extent the Owner orders additional  Products from the Vendor
in  accordance  with the terms of this Contract  including,  but not limited to,
subsections  2.2  and/or  7.2,  any such  Products  so  ordered by the Owner and
delivered and installed by the Vendor or its Subcontractors will be warranted to
the same  extent as set forth in clause  (a) above for a period of not less than

achievement  of Milestone 5 in such PCS System or PCS  Sub-System)  in any given
PCS  System or PCS  Sub-System,  as the case may be (the "RF  Services  Warranty
Period"), the Final Site Count within and the Final RF Design applicable to such
PCS System or PCS  Sub-System,  as the case may be, will be accurate  based upon
the  environmental  circumstances  in such PCS System or PCS Sub-System,  as the
case may be, as they  existed  at the time of the Final  Acceptance  of such PCS
System or PCS  Sub-System,  as the case may be, provided that the projections of
subscriber growth,  traffic and other predictive data,  including all applicable
standards as identified in Exhibits B1, D and H, upon which the Final Site Count
and Final RF Design have been determined,  have not been materially  exceeded or
the applicable and relevant industry standards have not materially changed;  and
provided further that in no event will the RF Engineering  warranty  pursuant to
this subsection 17.2(a) cover or warrant items or performance  otherwise covered
or warranted pursuant to subsection 17.3 below.

         (b) The  Vendor  warrants  that,  for a period of not less than two (2)
years from the date of completion of Facilities  Preparation Services within any
PCS System or PCS Sub-System, as the case may be, but in no event later than the

standards as identified in Exhibits B1, D and H, upon which the Final Site Count
and Final RF Design have been determined,  have not been materially  exceeded or
the applicable and relevant industry standards have not materially changed.

         17.4 Breach of Warranties. (a) In the event of any breach of any of the
Warranties  during  any  of  the  applicable   Warranty  Periods  set  forth  in
subsections  17.1(a),  17.2(a),  17.2(b),  17.2(c) and 17.3, the Vendor will, in
accordance  with the terms of this  Section 17,  promptly  repair or replace the
defective  or   nonconforming   Product  or  otherwise   cure  any  Defects  and
Deficiencies so that each PCS Sub-System and each PCS System and the System as a
whole will perform in accordance with the  Specifications  and Exhibit F. If the
Vendor fails to promptly repair, replace and/or cure such defect, the Owner may,
in addition to exercising any other remedies  available to it, itself cause such
repair,  replacement and/or cure, at its option and at the sole cost and expense
of the Vendor.

         (b) The Vendor  recognizes  that the Owner may suffer injury and may be
damaged in an amount which will be difficult  to determine  with  certainty as a
result of Outages  resulting  from  causes  attributable  to the  failure of the
Vendor's   Products   and/or   Services  to  perform  in  accordance   with  the
Specifications.   As  used  herein,   "Outage"  means  an  unscheduled  loss  of
functionality  of the System,  any PCS System or any PCS  Sub-System  due to the
failures of PCS Products or any  combination  thereof defined as the loss of the
capability to originate or terminate [___________] percent or more of the active
voice  channels then in service  within the System or such PCS System and/or PCS
Sub-System for a period of time exceeding [_____] minutes.

         (c) During the System Warranty Period, the Vendor will be liable to the
Owner for damages (the  "Warranty  Damages")  for Outages (for other than in the
Test-bed  Laboratory) that result from (i) the failure of the Vendor's Equipment
and/or  Software  to perform in  accordance  with the  Specifications,  (ii) the
failure of the Vendor to provide Services in accordance with the  Specifications
applicable thereto, (iii) a Vendor procedural error or (iv) inaccurate Technical
Documentation,   excluding  marketing  bulletins,   sales  literature  or  other
promotional  materials  provided  by the  Vendor to the Owner.  As used  herein,
"Vendor procedural error" means an error or improper deviation from the Vendor's
or  its  Subcontractors'   procedures  by,  or  attributable  to,  the  Vendor's
personnel.     Warranty     Damages    will    be    calculated    based    upon
[______________]dollars for each Outage occurring in any given PCS System to the
extent such Outage  exceeds  [__________]  from the time the Owner  notified the
Vendor of such Outage (not  including  such  [__________]),  plus  [___________]
dollars  per  minute  for  [___________]  the  duration  of the  Outage  exceeds
[___________]  from the time the Owner  notifies  the Vendor of such Outage (not
including such [__________]).  In the event any Outage is specific only to a PCS
Sub-System  and not any  other  portion  of the PCS  System  of  which  such PCS
Sub-System is a part (each a "PCS Sub-System Specific Outage"),  then the amount
of the Warranty Damages payable to the Owner for any such PCS Sub-System  Outage
pursuant  to the  terms  of  this  subsection  17.4(c)  will  be  calculated  by
multiplying the applicable  amounts set forth in this subsection  17.4(c) by the
percentage  equal to the Contract Price for such PCS  Sub-System  divided by the
Contract  Price for the entire PCS System of which such PCS Sub-System is a part
(for each PCS Sub-System, the "PCS Sub-System Percentage"). [______________].

         (d) In no event  will  the  Vendor's  liability  for  Warranty  Damages
pursuant to this  subsection 17.4 exceed  [___________]  dollars with respect to
each  Outage in any given PCS System;  provided  that the  Warranty  Damages cap
applicable to each PCS Sub-System Specific Outage will be [___________]  dollars
multiplied  by the  applicable  PCS  Sub-System  Percentage.  In  addition,  the
Vendor's total liability for Warranty  Damages  pursuant to this subsection 17.4
will not exceed [___________]  dollars per calendar year during the Term of this
Contract  with  respect to Outages  in any given PCS System per  calendar  year;
provided that the annual Warranty  Damages cap applicable to each PCS Sub-System
for all PCS Sub-System  Specific  Outages in each such PCS  Sub-System  will not
exceed  [___________]  dollars  multiplied  by  the  applicable  PCS  Sub-System
Percentage.

         (e)  Notwithstanding the foregoing, the Vendor will have no liability
pursuant to this subsection 17.4 for:

                                    (i) Outages  caused by a Force Majeure event
                           as  described  in Section 16 other than to the extent
                           that any of the  Vendor's  Products  and/or  Services
                           resulting in such Outages should,  in accordance with
                           the  Specifications  be able to  withstand  any  such
                           Force Majeure event;

                                    (ii)  Outages  resulting  from  a  scheduled
                           activity,  including,  but  not  limited  to,  System
                           maintenance  or  loading  of  Software  or  Equipment
                           Upgrades,  Enhancements or Combined Releases,  unless
                           said  Outage  (without  fault of the  Owner)  extends
                           beyond the  expected  downtime,  as  provided  in the
                           Specifications  applicable  thereto,  associated with
                           such  Equipment  or  Software  maintenance  Upgrades,
                           Enhancements or Combined Releases;

                                    (iii)  alterations  by the Owner  and/or the
                           Vendor at the Owner's  request or otherwise  pursuant
                           to the terms of this  Contract  to the System  and/or
                           any PCS System and/or any PCS  Sub-System,  excluding
                           normal maintenance or parameter changes as prescribed
                           by the applicable Technical Documentation;

                                    (iv) Outages resulting from the Owner's, its
                           subcontractors'  or any third  party's (if such third
                           party is employed by the Owner) failure to follow the
                           Technical Documentation;

                                    (v) Outages  resulting from the  negligence,
                           gross negligence or willful  misconduct of the Owner,
                           or any of its employees, agents or contractors or any
                           other third party  (other than any  Subcontractor  or
                           any  employees,  representatives  or  agents  of  the
                           Vendor); or

                                    (vi)  Outages   resulting  from  failure  of
                           equipment  or software  not supplied by the Vendor or
                           any   Subcontractors   or  from  the  performance  of
                           services   not   performed   by  the  Vendor  or  any
                           Subcontractors; or

                                    (vii)   Outages   caused   by  the   Owner's
                           deactivation  of the System or any  portion  thereof,
                           unless the deactivation is undertaken in avoidance of
                           an unplanned outage; or

                                    (viii)  Outages caused by the failure of the
                           Network Interconnection facilities.

         (f) On or before the  beginning of each quarter of each  calendar  year
during the Term of this  Contract,  the Owner will  provide the Vendor a written
report  summarizing any Outages  occurring during the previous calendar quarter.
The amount of any Warranty Damages will be determined by the Owner as of the end
of the fourth  quarter of each calendar year during the Term,  for the preceding
four  quarterly  reporting  periods  during such Term. The Owner will notify the
Vendor of any such Warranty Damages in writing.  Such Damages will be payable in
credits on future purchases under this Contract or otherwise if this Contract is
terminated  for any  reason  within  thirty  (30)  days of the  occurrence.  Any
disputes  regarding the determination of the cause of an Outage or the amount of
any such Warranty  Damages will be resolved in accordance with the provisions of
Section 23.

         17.5  Repair and Return.  (a) If the Owner  claims a breach of warranty
under  subsections  17.1, 17.2 or 17.3, it must notify the Vendor of the claimed
breach  within a reasonable  time after its  determination  that a breach has in
fact  occurred.  The Owner will allow the Vendor to inspect  the  Products,  the
Services  or the System,  as the case may be,  on-site,  or,  upon the  Vendor's
reasonable  request and,  subject to subsection  17.5(d) below,  at the Vendor's
sole expense:  (i) with respect to Products,  return such Products to any of the
Vendor's repair  facilities  located in the United States and listed on Schedule
8, or (ii) with respect to Non-Essential  Equipment,  return such  Non-Essential
Equipment  to the  Vendor  (or to the third  party  manufacturer  if  previously
requested  by the  Vendor)  for  further  return to the  applicable  third party
manufacturer.  The Vendor or such third party  manufacturer  may use either new,
remanufactured,  reconditioned, refurbished, or functionally equivalent Products
or parts pursuant to the terms of this Contract,  including, but not limited to,
the Specifications,  in the furnishing of warranty repairs or replacements under
this Contract.

         (b)  The  Vendor  agrees  to  commence  work  on  all  such   Products,
Non-Essential  Equipment,  Services or any System Defect, as the case may be, or
Installation defects as soon as practicable,  but the Vendor will use reasonable
efforts to  commence  such Work in no event  later than  twenty-four  (24) hours
after  notification  of such defect,  and,  subject to  subsections  17.5(e) and
17.5(f), the Vendor will cure such defect as promptly as practicable. During the
Product  Warranty  Period  electronic  circuit board  components of Equipment or
Non-Essential Equipment, as the case may be, will be repaired or replaced by the
Vendor.

         (c) Failure of the System to  function to the level of the  performance
warranty as set forth in  subsection  17.3 will result in the  obligation of the
Vendor to promptly make whatever repairs, modifications, alterations, expansions
or to take any other  action  of any  kind,  including  but not  limited  to the
provision of additional  Products and/or Services,  necessary to  satisfactorily
fix that  portion  of the System  causing  any  failure  for which the Vendor is
responsible. In the event of a breach of the warranties in Section 17 which will
be cured with the  installation  of  additional  PCS  Products,  the Vendor will
provide such PCS Products,  together with related  transportation,  Installation
and optimization  Services,  as are reasonably required to remedy the shortfall,
at no charge to the Owner,  provided  that, if in order to remedy the shortfall,
the number of  additional  Base  Stations  required to cure the Vendor's  breach
under these warranties is not in excess of five percent (5%) of the total number
of Base  Stations in the relevant  PCS System (as such "total  number" is as set
forth in the Final RF Engineering Plan), the Vendor will not be obligated to pay
for the Base Stations and the  installation and  transportation  related thereto
required to cure such breach, provided further that the Vendor will be obligated
to provide and pay for any Base Stations and the installation and transportation
related thereto in excess of any such five percent (5%) shortfall.

         (d) All  costs  associated  with  (i)  removing  or  disconnecting  the
Products or the  Non-Essential  Equipment subject to the warranty claim pursuant
to the terms of this  Section 17 from any other  Products,  the  respective  PCS
System or PCS Sub-System or any part thereof or from other equipment,  any other
PCS system or any part thereof to which they are attached or connected,  or (ii)
dismantling surrounding Products, the respective PCS System or PCS Sub-System or
any part thereof or any other  equipment or other PCS system or any part thereof
in order to so remove or  disconnect  the  Products or  Non-Essential  Equipment
subject  to such  warranty  claim  will be borne by the  Vendor  throughout  the
applicable  Warranty  Period unless such Products are readily  returnable to the
Vendor in which case the Owner will bear all such costs. All packaging, shipping
and  freight  charges  incurred  in  connection  with the return of Items to the
Vendor will be borne by the Owner.  The Vendor will be responsible  for packing,
shipping and freight charges for return of repaired or replacement  Items to the
Owner,  unless the  Products  or  Non-Essential  Equipment,  as the case may be,
returned are not  Defective or  otherwise  not covered by the Vendor's  warranty
pursuant  to  subsection  17.1,  in which  case the Owner  will pay for all such
charges between the Owner's point of origin and the Vendor's  applicable  repair
facility in the United States.

         (e)  For  routine  warranty  service,   the  Vendor  will,  during  the
respective   Warranty  Period,   ship   replacement  or  repaired   Products  or
Non-Essential  Equipment  (or  components  thereof)  within  thirty (30) days of
receipt of the Defective  Equipment or  Non-Essential  Equipment (or  components
thereof) from the Owner. In the event such  replacement or repaired  Products or
Non-Essential  Equipment  cannot be shipped  within such time period,  or if the
Vendor determines that due to the particular  circumstances,  on-site repairs or
services are required,  the Vendor will  undertake  such repairs or  replacement
services  on-site within thirty (30) days of notification of the warranty Defect
by the Owner. In the event that the Vendor fails to repair or replace  Defective
Products and/or Non-Essential Equipment within thirty (30) days from the Owner's
notice  to the  Vendor,  then the  Vendor  will be deemed to be in breach of its
obligations  pursuant to this Contract and the Owner will be entitled to receive
a refund of all amounts previously paid to the Vendor for the Defective Products
or  Non-Essential  Equipment,  and  will  have  no  further  obligation  to  pay
additional  amounts in connection with the Defective  Products or  Non-Essential
Equipment.  The Owner will  return such  Defective  Products  and  Non-Essential
Equipment to the Vendor at the Vendor's sole cost and expense.

         (f) For emergency warranty service situations,  the Vendor will, during
the  applicable  Warranty  Periods,  use its best  efforts  to ship  replacement
Products or Non-Essential Equipment (or components thereof) no later than twelve
(12) hours after  notification  of the warranty  Defect by the Owner.  The Owner
will ship the Defective Products or Non-Essential Equipment to the Vendor within
thirty  (30)  days of  receipt  of the  replacement  Products  or  Non-Essential
Equipment,  as the case may be. In the event the Vendor  fails to  receive  such
Defective  Products  or  Non-Essential  Equipment  within  such  thirty (30) day
period,  the Vendor  will  invoice  the Owner for the  replacement  Products  or
Non-Essential Equipment at the then-current price in effect therefor pursuant to
the terms of this Contract.  If in an emergency warranty service situation,  the
Owner and/or the Vendor  determines  that due to the  particular  circumstances,
on-site technical  assistance is necessary,  the Vendor will dispatch  emergency
service  personnel to the site in accordance with the terms of subsection  2.26.
For the purpose of this subsection 17.5, an emergency warranty service situation
will be deemed to exist upon the occurrence of any E1 Emergency  Condition or E2
Emergency  Condition.  The  Vendor  agrees to  commence  work on all  Equipment,
Non-Essential  Equipment,  Facilities Preparation Services or any System defect,
as the case may be, or  Installation  defects  materially  impairing  service to
subscribers,  System performance,  billing, administration and/or maintenance as
soon as  practicable,  but in no event later than  twenty-four  (24) hours after
notification of such defect, and the Vendor will cure such defect as promptly as
practicable.

         17.6 Technical  Assistance Center. The Vendor must maintain a technical
assistance  center  in the  United  States,  and  during  the  Warranty  Periods
established   pursuant  to  subsections   17.1(a),   17.1(b),   17.2  and  17.3,
respectively,  will make such support center available to the Owner  twenty-four
(24)  hours  per day free of any  additional  charge to the  Owner  (other  than
applicable Annual Release Maintenance Fees).

             SECTION 20 INDEMNIFICATION AND LIMITATION OF LIABILITY

         20.1 Vendor Indemnity. (a) The Vendor will indemnify and hold the Owner
and its Affiliates,  partners,  directors,  officers,  agents and employees (the
"Indemnitees")  harmless from and against all third party claims, demands suits,
proceedings,   damages,  costs,  expenses,   liabilities   (including,   without
limitation,   reasonable   legal  fees)  or  causes  of  action   (collectively,
"Liabilities")  brought  against or incurred by any Indemnitee for (i) injury to
persons (including physical or mental injury, libel, slander and death), or (ii)
loss or  damage  to any  property,  or  (iii)  violations  of  Applicable  Laws,
Applicable Permits,  codes, ordinances or regulations by the Vendor, or (iv) any
patent or trademark  claims  arising out of the Vendor's  obligation  subject to
subsection  14.2  or (v)  any  other  liability,  resulting  from  the  acts  or
omissions,  negligence,  error,  willful misconduct or strict liability,  of the
Vendor, its officers, agents, employees, or Subcontractors in the performance of
this Contract.  If the Vendor and the Owner jointly cause such Liabilities,  the
Parties will share the  liability in proportion  to their  respective  degree of
causal responsibility.

         (b) The Vendor's  obligation to indemnify under subsection 20.1(a) with
respect to any Liability  will not arise unless the Owner or the  Indemnitee (i)
notifies the Vendor in writing of such potential  Liability,  in the case of the
Owner,  within a reasonable  time after the Owner will receive written notice of
such  Liability;  provided  that the lack of such  notice  will not  affect  the
Vendor's obligation  hereunder (A) if the Vendor otherwise has knowledge of such
Liability  and (B) unless  such lack of notice is the cause of the Vendor  being
unable to adequately and reasonably defend such Liability, (ii) gives the Vendor
the  opportunity  and  authority  to  assume  the  defense  of and  settle  such
Liability,  subject  to the  provisions  of the next two  sentences,  and  (iii)
furnishes to the Vendor all such reasonable information and assistance available
to the Owner (or other Indemnitees) as may be reasonably requested by the Vendor
and necessary for the defense against such Liability.  The Vendor will assume on
behalf of the  Indemnitee  and conduct with due  diligence and in good faith the
defense of such Liability with counsel (including  in-house counsel)  reasonably
satisfactory to the Indemnitee; provided that the Indemnitee will have the right
to be  represented  therein by advisory  counsel of its own selection and at its
own expense. If the Indemnitee will have reasonably  concluded that there may be
legal  defenses  available to it which are different  from or additional  to, or
inconsistent  with, those available to the Vendor,  the Indemnitee will have the
right to  select  separate  counsel  reasonably  satisfactory  to the  Vendor to
participate  in the  defense of such  action on its own  behalf at the  Vendor's
expense.  In the event the Vendor  fails to defend any  Liability as to which an
indemnity  might be provided  herein,  then the Indemnitee  may, at the Vendor's
expense,  contest or settle  such  matter  without  the  Vendor's  consent.  All
payments,  losses,  damages  and  reasonable  costs  and  expenses  incurred  in
connection  with such  contest,  payment or  settlement  will be to the Vendor's
account and may be deducted from any amounts due to the Vendor.  The Vendor will
not settle any such Liability  without consent of the Indemnitee,  which consent
will  not be  unreasonably  withheld.  This  indemnity  is in lieu of all  other
obligations  of the  Vendor,  expressed  or  implied,  in law or in  equity,  to
indemnify  the  Indemnitees  (except  pursuant to Section 14 or any other Vendor
indemnitees set forth in this Contract).

         20.2 LIMITATION ON LIABILITY.  EXCEPT AS PROVIDED IN SUBSECTIONS  14.2,
15.2, 15.3, 15.4,  15.5,  15.6,  15.7, 15.8, 15.9,  15.10,  17.4, 20.1, AND 20.3
HEREOF,  IN NO EVENT,  AS A RESULT OF BREACH OF CONTRACT OR BREACH OF  WARRANTY,
WILL EITHER PARTY  HERETO BE LIABLE  UNDER THIS  CONTRACT TO THE OTHER PARTY FOR
ANY CONSEQUENTIAL OR INCIDENTAL  DAMAGES,  INCLUDING LOST PROFITS OR REVENUES OF
SUCH  PARTY,  BEFORE  OR  AFTER  ACCEPTANCE,  WHETHER  OR NOT SUCH  DAMAGES  ARE
FORESEEABLE.

         20.3  Damages  for Fraud or Willful  Misconduct  (a) The Vendor will be
responsible for all damages, including without limitation,  indirect, incidental
and  consequential  damages,  incurred by the Owner as a result of any damage or
injury  caused by or  resulting  from the  fraud or  willful  misconduct  of the
Vendor.
(-)
         (b) The Vendor  will be  responsible  for all  damages,  but  excluding
indirect,  incidental  and  consequential  damages,  incurred  by the Owner as a
result of any damages or injury  caused by or  resulting  from the fraud,  gross
negligence  or willful  misconduct of any of the  Subcontractors  related to the
performance of the Work, to the extent the Vendor would have liability  therefor
under this Contract if the Vendor had engaged in such conduct.

                        SECTION 22 TITLE AND RISK OF LOSS

         22.1 Title.  Title to each Item of Equipment  (but in no case Software)

                          SECTION 23 DISPUTE RESOLUTION

         23.1 Dispute  Resolution.  Subject to  subsection  23.4 and  subsection
24.3,   in  the  event  any   controversy,   claim,   dispute,   difference   or
misunderstanding  arises  out of or  relates  to  this  Contract,  any  term  or
condition  hereof,  any of the Work to be performed  hereunder or in  connection
herewith,  the respective  System Managers of the Owner and the Vendor will meet
and negotiate in good faith in an attempt to amicably resolve such  controversy,
claim, dispute,  difference or misunderstanding in writing. Such System Managers
must meet for this purpose  within ten (10)  Business  Days,  or such other time
period  mutually  agreed  to by the  Parties,  after  such  controversy,  claim,
dispute,  difference or  misunderstanding  arises.  If the Parties are unable to
resolve the controversy,  claim, dispute, difference or misunderstanding through
good faith  negotiations  within such ten (10)  business day period,  each Party
will,  within  five (5)  Business  Days  after the  expiration  of such ten (10)
business day period,  prepare a written position  statement which summarizes the
unresolved issues and such Party's proposed resolution.  Such position statement
must be delivered by the Vendor to the Owner's Vice  President of Engineering or
Operations  and  by  the  Owner  to  the  Vendor's   corresponding   officer  or
representative  for  resolution  within (5)  Business  Days,  or such other time
period mutually agreed to by the Parties.

         If the Parties continue to be unable to resolve the controversy, claim,
dispute,  difference or misunderstanding,  either Party may initiate arbitration
in accordance with the provisions of subsection 23.2 below;  provided,  however,
that  with  respect  to  any   controversy,   claim,   dispute,   difference  or
misunderstanding  arising out of or relating  to this  Contract by which  either
Party seeks to obtain from the other  monetary  damages in excess of twenty-five
million  dollars  ($25,000,000),  either  Party,  in such case,  may commence an
action in any state or  federal  court in  accordance  with  subsection  27.7 to
resolve such matter in lieu of proceeding with an arbitration pursuant to and in
accordance  with  subsection  23.2. The  arbitrators  hired or otherwise  chosen
pursuant to and in accordance  with the terms of this  Contract  will  determine
issues of  arbitrability  pursuant to the terms of this  Contract but may not in
any way limit,  expand or otherwise  modify the terms of this  Contract nor will
they  have any  authority  to award  punitive  or other  damages  in  excess  of
compensatory damages (other than as specifically set forth in this Contract) and
each  Party  irrevocably  waives  any  such  claim  thereto  when  invoking  the
arbitration provisions of subsection 23.2.

         23.2 Arbitration.  An arbitration  proceeding initiated by either Party
under this Contract with respect to any controversy,  claim, dispute, difference
or  misunderstanding  will be conducted in Kansas City,  Missouri in  accordance
with the Commercial Arbitration rules of the AAA, except that, at the request of
either Party, a stenographic transcript of the testimony and proceedings will be
taken and the  arbitrators  will base their decision upon the records and briefs
of the Parties.

         Such  arbitration  will be initiated  by either Party by notifying  the
other  Party  in  writing  and  will  be  settled  before  three  (3)  impartial
arbitrators,  one of whom will be named by the Owner,  one by the Vendor and the
third  by  the  two   arbitrators   appointed  by  the  Owner  and  the  Vendor,
respectively.  All of the named arbitrators will have significant  experience in
the  wireless  telecommunications  industry.  If either  the Owner or the Vendor
fails to select an  arbitrator  within ten (10) days after notice has been given
of the initiation of the arbitration,  the officer in charge of the Kansas City,
Missouri office of the AAA will have the right to appoint the other  arbitrator,
and the two arbitrators thus chosen will then select the third arbitrator.

         Except as the Parties may otherwise  mutually  agree,  the  arbitration
hearings  will  commence  within  fifteen  (15)  Business  Days  after a Party's
initiation  of the  arbitration.  The Federal  Rules of Evidence  will apply and
reasonable discovery, including depositions, will be permitted. Discovery issues
will be decided by the arbitrators and post-hearing briefs will be permitted.

         The  arbitrators  will render a decision within ten (10) days after the
conclusion of the hearing(s) and submission of post-hearing briefs and a written
opinion  setting  forth  findings  of fact and  conclusions  of law will be made
available to the Parties  within that time period.  The decision of the majority
of the arbitrators regarding the matter submitted will be final and binding upon
the Parties.  Judgment upon the award rendered by the arbitrators may be entered
in any court having jurisdiction thereof.

         Each Party will pay for the  services  and  expenses of the  arbitrator
appointed by it, its witnesses and  attorneys,  and all other costs  incurred in
connection with the arbitration (including,  without limitation, the cost of the
services  and  expenses  of the  arbitrator  appointed  by the  two  arbitrators
appointed by the Parties) will be paid in equal part by the Parties,  unless the
award  will  specify  a  different  division  of  the  costs.  Unless  otherwise
specifically  stated in this  Contract,  during the pendency of any  arbitration
proceedings,  the  Parties  agree  to  continue  to  perform  their  obligations
hereunder  in the  same  manner  as  prior  to the  institution  of  arbitration
proceedings.

         23.3 Third Party Engineer. Disputes arising under subsections 2.6, 2.7,
9.5(b),  9.6,  10.1  and 17.4 of this  Contract,  or as  otherwise  specifically
provided  elsewhere in this  Contract,  or as otherwise  mutually  agreed by the
Parties,  are to be resolved by the Third Party Engineer in the manner  provided
in this subsection  23.3. The Vendor and the Buyer will first attempt to resolve
the dispute through  consultation  and negotiation in good faith and in a spirit
of mutual  cooperation as provided in subsection  23.1 above.  If those attempts
fail,  then  either  Party may  submit  its  written  notice to the other  Party
requesting  that the  dispute  be  resolved  by the  Third  Party  Engineer,  in
accordance  with the merits of the dispute.  If,  within ten (10)  Business Days
after the  receipt of such  notice by the  notified  Party,  the  dispute is not
resolved,  the Owner will  select  one of the Third  Party  Engineers  listed on
Schedule 14 to render  decision in the dispute.  The Third Party  Engineer  will
issue a written  decision  containing an explanation of how and why the decision
was  reached.  The Third Party  Engineer's  decision  will be final and binding,
except  with  respect to any  opinion  that over the Term of the  Contract  will
impact the losing  Party in the amount of one million  dollars  ($1,000,000)  or
more.  If within ten (10)  Business  Days  following  the  issuance  of any such
opinion the Parties have not agreed to  implement  the terms of any such opinion
that is not final, either Party may seek arbitration  pursuant to the provisions
of subsection 23.2 above. In such  arbitration,  either Party may introduce into
evidence the opinion of the Third Party  Engineer,  but the  arbitrator(s)  must
rule on all issues of the dispute on a de novo basis,  except as to any facts or
other matters set forth in the opinion and stipulated by both of the Parties. If
none of the listed  Third Party  Engineers  is  available or if none accepts the
assignment  and the Parties  cannot  otherwise  mutually  agree to another Third
Party Engineer,  an experienced  and reputable  engineer (who is not employed by
either Party or any of their  Affiliates  or  affiliates)  will be chosen by the
then President of the Institute of Electrical  and Electronic  Engineers (or the
Vice  President,  if the  President is a present or former  employee of any such
entities) to serve as the Third Party Engineer for the purposes of resolving the
dispute.  Unless otherwise mutually agreed by the Parties,  any Person who is an
officer or employee,  agent,  Subcontractor or subcontractor  of, or a technical
consultant  to,  either Party will be  automatically  ineligible to be the Third
Party  Engineer.  The costs of  utilizing  a Third  Party  Engineer  to  resolve
disputes under this subsection 23.3 will be shared equally by both Parties.

         23.4 Other  Remedies.  Notwithstanding  anything to the contrary herein
contained,  each  Party will be  entitled  to pursue  any  equitable  rights and
remedies  that  are  available  at  law  or in  equity  without  complying  with
subsection 23.2 or 23.3.

         23.5 Tolling.  All applicable  statutes of limitation will be tolled to
the extent permitted by Applicable Law while the dispute  resolution  procedures
specified in this Section 23 are pending,  and nothing  herein will be deemed to
bar any Party from  taking such  action as the Party may  reasonably  deem to be
required to effectuate such tolling.

                  SECTION 24 TERMINATION AND EVENTS OF DEFAULT

         24.1 Termination  Without Cause. (a) The Owner may, at its sole option,
terminate this Contract, in its entirety, for convenience upon ninety (90) days'
prior written  notice at any time;  provided that prior to any such  termination
pursuant to this subsection 24.1 the Minimum Commitment will have been fulfilled
by the Owner in accordance with the terms of this Contract.

         (b) Any  orders  for  Vendor  Work  within  any PCS  System  and/or PCS
Sub-System  within the System made by the Owner  pursuant  to and in  accordance
with the terms of this  Contract and the program  management  procedures  of the
Owner prior to any such  termination  described in clause (a) above,  other than
the  Initial  Commitment,  will  remain in effect and will be  fulfilled  to the
extent that such orders are outstanding as of the date of such termination.  For
the purposes of this subsection  24.1(b) an "order" will not include the Initial
Commitment  or any order  for a full PCS  System or PCS  Sub-System  within  the
Initial System or the System.

         24.2  Termination for Cause.  The Owner also has the right to terminate
this  Contract  in its  entirety  (except as  otherwise  set forth in clause (l)
below)  without any penalty or payment  obligation  upon the  occurrence  of any
Vendor event of default  (each a "Vendor  Event of Default") as set forth below.
The  occurrence  of any of the  following  will  constitute  a  Vendor  Event of
Default:

         (a) the Vendor (i) files a voluntary  petition in  bankruptcy or has an
involuntary petition in bankruptcy filed against it that is not dismissed within
forty-five  (45) days of such  involuntary  filing,  (ii)  admits  the  material
allegations  of any petition in  bankruptcy  filed against it, (iii) is adjudged
bankrupt,  or (iv) makes a general  assignment for the benefit of its creditors,
or if a receiver is appointed for all or a substantial portion of its assets and
is not discharged within sixty (60) days after his appointment; or

         (b)  the Vendor commences any proceeding for relief from its creditors
in any court under any state insolvency statutes; or

         (c)  the Vendor materially disregards or materially violates material
Applicable Laws or material Applicable Permits; or

         (d)  the Vendor persistently and materially allows Defects and Defi-
ciencies to exist; or

         (e) the Vendor  fails to fulfill its  obligations  with  respect to the
satisfaction,  discharge  or  bonding of liens as set forth in  subsection  2.36
hereof; or

         (f) the Vendor abandons or ceases for a period in excess of thirty (30)
days its  performance  of the Work  (except as a result of a  casualty  which is
fully covered by insurance or as to which other provisions reasonably acceptable
to the Owner are being  diligently  pursued)  or fails to begin the Work  within
thirty (30) days after the Notice to Proceed Date; or

         (g)  the Vendor assigns or subcontracts Work other than as provided for
in this Contract; or

         (h)  the Vendor fails to materially comply with any Change Order; or

         (i) the  Vendor  fails to perform  this  Contract  (including,  without
limitation,  any action the Vendor may take on any  Vendor-Controlled  Site) and
thereby prejudices in any way deemed material by the parties providing financing
in connection  with the build-out of the Nationwide  Network and/or the Owner in
their reasonable  opinion the Owner's efforts to obtain financing for the System
and/or the Nationwide System; or

         (j)  the Vendor fails to pay to the Owner any material amount due to
the Owner by the date required for such payment; or

         (k)  the Vendor fails to comply with subsection 27.22;

         (l) the Vendor misses any Interim Milestone within any given PCS System
or PCS  Sub-System by a period in excess of thirty (30) days and such failure to
achieve  such  Interim  Milestone  was not caused by (i) a Force  Majeure  event
and/or  (ii) any act or omission  of the Owner;  provided  that in such case the
Owner will have the right,  but not the  obligation,  to terminate this Contract
with  respect to only that PCS System or PCS  Sub-System  in which such  interim
delay occurred unless such interim delay relates to Milestone 4 (as set forth on
Exhibit A1) in which case the Owner will have the right, but not the obligation,
to  terminate  this  Contract  in its  entirety as  otherwise  set forth in this
subsection 24.2; or

         (m)  the Vendor otherwise materially breaches any provision of this
Contract.

         24.3 Remedies.  (a) If any of the Vendor Events of Default exists,  the
Owner may,  without  prejudice  to any other  rights or remedies of the Owner in
this  Contract or at law or in equity,  terminate  this  Contract  upon  written
notice to the Vendor; provided, however, that the Owner will have first provided
to the Vendor the following periods of notice and opportunity to cure:

                  (i) in the  case  of an  Event  of  Default  specified  in the
         foregoing  clauses (e) and (k), the Owner will have provided  seven (7)
         days'  prior  written  notice to the  Vendor,  and the Vendor will have
         failed to remedy such breach  entirely by the end of such seven (7) day
         period;

                  (ii) in the  case of an  Event  of  Default  specified  in the
         foregoing  clauses (a) or (b), no notice or opportunity to cure will be
         required from the Owner; and

                  (iii) in the case of any other Event of Default by the Vendor,
         the Owner  will have  provided  forty-five  (45)  days'  prior  written
         notice,  and the Vendor  will have  failed (i) to  commence to cure the
         default  within five (5) days of delivery of such  notice,  and (ii) to
         diligently  pursue such cure and remedy the breach  entirely by the end
         of said forty-five (45) day notice period.

         (b) If the Owner  elects to  terminate  this  Contract,  the Owner may,
without  prejudice to any other rights or remedies of the Owner in this Contract
or of law or in equity, do one or more of the following:

                  (i)  Take  possession  of all  Engineering  and  design  data,
         procurement data,  manufacturing data,  construction and erection data,
         start-up and testing  data,  materials,  and Products  that will become
         part  of the  System  and/or  the  specified  PCS  Systems  and/or  the
         specified PCS Sub-Systems, or the Work, whether any of the same is in a
         partial state of completion or completed condition, and title to any of
         said items vests in the Owner (if not already  vested by the provisions
         of this Contract);

                  (ii)  Take  temporary  possession  and  control  of all of the
         Vendor's installation equipment, machinery, and the Vendor's materials,
         supplies,  Software and any and all tools  (including,  but not limited
         to, any and all RF  Engineering  tools and/or  software) at any project
         site, including but not limited to any System Element Location,  within
         the System and/or the  specified  PCS Systems  and/or the specified PCS
         Sub-Systems  which in the Owner's  opinion are  necessary to finish the
         Work;

                  (iii)  Direct  that  the  Vendor   assign  its   Subcontractor
         agreements  to the Owner  without  any  change  of price or  conditions
         therein or penalty or payment therefor; or

                  (iv)  Take over and finish the Work by whatever reasonable
methods the Owner may deem expedient;

provided,  that,  nothing  contained  in  paragraphs  (a) through (d) above will
require  the  Vendor  to  relinquish  to the  Owner  any  of  its  manufacturing
facilities,  specific  Product  designs  (other  than  such  designs  previously
provided to the Owner pursuant to the terms of this  Contract),  Software Source
Codes, trade secrets or proprietary  information not previously provided or made
available  to the  Owner,  the  System  or any part  thereof  or any  materials,
supplies,  inventories, tools, software, engineering and/or designs that are not
integral or relevant to the completion of the Work.

         24.4 Discontinuance of Work. Upon such notification of termination, the
Vendor  must  immediately  discontinue  all of the Work  (unless  such notice of
termination  directs  otherwise),  and,  as more  fully set forth in  subsection
24.3(b)  clauses  (i)  through  (iv),  deliver to the Owner  copies of all data,
drawings,   specifications,   reports,  estimates,  summaries,  and  such  other
information,  and  materials  as may have  been  accumulated  by the  Vendor  in
performing the Work,  whether completed or in process.  Furthermore,  the Vendor
must  assign,  assemble  and  deliver  to the  Owner  all  purchase  orders  and
Subcontractor agreements requested by the Owner.

         24.5  Payments.  When the  Owner  terminates  this  Contract  for cause
pursuant to subsection  24.2, the Vendor will not be entitled to receive further
payment  other than payments due and payable under this Contract and not subject
to dispute prior to such  termination  (provided that any such disputed  amounts
will  be paid by the  Owner  when  and if  such  dispute  is in fact  resolved).
Notwithstanding  anything  herein  to  the  contrary,  the  Owner  may  withhold
payments,  if any, to the Vendor for the  purposes of offset of amounts  owed to
the Owner  pursuant to the terms of this  Contract  until such time as the exact
amount of damages due the Owner from the Vendor is fully determined.

         24.6  Costs.  In the event of a  termination  due to a Vendor  Event of
Default,  the Owner will be entitled to the costs in connection  with  finishing
the Work  (exclusive of any Liquidated  Damages already paid and/or owing to the
Owner upon  termination of this  Contract),  and if such costs exceed the unpaid
balance of the Contract  Price,  the Vendor will be liable to pay such excess to
the Owner.  The amount to be paid by the Vendor pursuant to this subsection 24.6
will survive termination of this Contract and will be subject to the limitations
of liability in this Contract.

         24.7  Continuing  Obligations.  Termination  of this  Contract  for any
reason (i) will not relieve either Party of its obligations  with respect to the
confidentiality of the Proprietary Information as set forth in subsection 27.19,
(ii) will not relieve  either Party of any  obligation  which  applies to it and
which  expressly or by  implication  survives  termination,  and (iii) except as
otherwise  provided in any  provision of this  Contract  expressly  limiting the
liability of either Party,  will not relieve either Party of any  obligations or
liabilities  for loss or damage to the other  Party  arising out of or caused by
acts or omissions of such Party prior to the  effectiveness  of such termination
or arising out of its  obligations as to portions of the Work already  performed
or of obligations assumed by the Vendor prior to the date of such termination.

         24.8 Vendor's  Right to  Terminate.  The Vendor will have the option to
terminate this Contract without any penalty or payment  obligations,  other than
undisputed  payment  obligations   outstanding  as  of  the  date  of  any  such
termination pursuant to the terms of this Contract if:

         (a) the Owner (i) files a voluntary  petition in  bankruptcy  or has an
involuntary petition in bankruptcy filed against it that is not dismissed within
forty-five  (45) days of such  involuntary  filing,  (ii)  admits  the  material
allegations  of any petition in  bankruptcy  filed against it, (iii) is adjudged
bankrupt,  or (iv) makes a general  assignment for the benefit of its creditors,
or if a receiver is appointed for all or a substantial portion of its assets and
is not  discharged  within sixty (60) days after his  appointment,  and any such
filing,  proceeding,  adjudication or assignment as described  herein above will
otherwise materially impair the Owner's ability to perform its obligations under
this Contract;

         (b)  the Owner commences any proceeding for relief in any court under
any state insolvency statutes;

         (c) the Owner fails to make payments of  undisputed  amounts due to the
Vendor  pursuant  to the terms of this  Contract  which are more than sixty (60)
days overdue,  provided that such failure has continued for at least thirty (30)
days  after the  Vendor  has  notified  the Owner of its right and  intent to so
terminate on account of such overdue amount;

         (d) the Owner persistently and materially  breaches  subsection 11.1 or
subsection 27.19 notwithstanding the fact that the Vendor will have provided the
Owner with prior written  notice  describing the alleged  material  breaches and
will have given the Owner a reasonable  time (not less than thirty (30) days) to
cure any such breaches; or

         (e) except as otherwise  provided in subsection 24.1 the Owner fails to
fulfill its Initial  Commitment  within five (5) years of the Effective Date for
whatever  reason other than (i) any act or omission of the Vendor,  (ii) failure
or inability to  successfully  complete  Microwave  Relocation in any PCS System
and/or PCS Sub-System,  (iii) failure or inability to  successfully  attain Site
Acquisition Substantial Completion in any given PCS System and/or PCS Sub-System
or (iv) any event otherwise constituting a Force Majeure hereunder.

         24.9 Special  Termination  Events.  (a) In the event that financing for
the Owner's  build-out of the initial  phase of the  Nationwide  Network has not
been  finalized  with the Vendor and the Other  Vendors on terms and  conditions
reasonably  satisfactory to the Owner, on or before one hundred and eighty (180)
days  after  January  31,  1996,  the  Owner  will have the  right,  but not the
obligation, to terminate this Contract in its entirety without charge or penalty
of any kind.  In the event of a termination  of this  Contract  pursuant to this
subsection  24.9(a) the Owner will  remain  liable for amounts due to the Vendor
for all  Work  performed  or  Products  delivered  by the  Vendor  or any of its
Subcontractors  pursuant to the specific  terms of this Contract  which had been
directly delivered to or performed for the Owner and/or any of its facilities or
sites in accordance with the terms of this Contract  including,  but not limited
to,  the  Project  Milestones.  Any  amounts  owed by the Owner for Work done or
Products  delivered  by the Vendor  during  such  interim one hundred and eighty
(180) day period (the "Financing  Interim Period") not otherwise invoiced to the
Owner by the Vendor prior to the  termination of such Financing  Interim Period,
will be invoiced to the Owner by the Vendor within thirty (30) days (but failure
to so invoice will not excuse the Owner's obligation to otherwise pay the Vendor
pursuant to the terms of this subsection  24.9(a)) of such termination  pursuant
to this  subsection  24.9(a) and will be payable to the extent not  otherwise in
dispute  by the Owner  within  thirty  (30)  days of  receipt  of such  invoice;
provided  that in no event  will the  Owner be  liable  to the  Vendor  due to a
termination of this Contract pursuant to this subsection  24.9(a) for any of the
Vendor's  direct or indirect costs or expenses  incurred in connection  with any
supplies or equipment  ordered by the Vendor or  agreements  entered into by the
Vendor  in order  to  enable  it to  fulfill  its  obligations  hereunder  or in
connection  with the  establishment  of  and/or  upgrade  to its  manufacturing,
personnel,  engineering,  administrative or other capacities and/or resources in
contemplation  of or pursuant to its performance in accordance with the terms of
this  Contract  and any  amounts due to the Vendor  pursuant to this  subsection
24.9(a)  will be  limited  in all cases to Work  actually  done or  Products  or
Services actually delivered to the Owner, its sites or its facilities.

         (b) If at any time after the  Effective  Date any material  change will
have  occurred in any  Applicable  Law or in the  interpretation  thereof by any
Governmental  Entity,  or there will be rendered any decision in any judicial or
administrative  case,  in either case which,  in the  reasonable  opinion of the
Owner, would make the Owner's use of any part of any PCS System illegal or would
subject  the  Owner or any of its  Affiliates  to any  material  penalty,  other
material  liability or onerous condition or to any burdensome  regulation by any
Governmental  Entity or otherwise  render the use of such PCS System  and/or PCS
Sub-System economically nonviable,  then, with respect to such PCS System and/or
PCS Sub-System,  or affected part thereof,  or with respect to the entire System
if so affected,  the Owner may terminate this Contract without charge or penalty
of any kind;  provided that (i) the Owner gives the Vendor prior written  notice
of any such change or decision;  (ii) that the Owner uses its reasonable efforts
for a reasonable  time to reverse or  ameliorate  such change or decision to the
extent possible or practical  prior to declaring such  termination and (iii) the
Owner,  at the  Vendor's  request,  gives  the  Vendor  a legal  opinion  from a
reputable law firm with experience in the area confirming the Owner's reasonable
opinion  as set forth  above.  In the event of a  termination  pursuant  to this
subsection 24.9(b),  payment obligations incurred by the Owner for Work actually
done or Products  or Services  actually  delivered  by the Vendor  prior to such
termination pursuant to this Contract will be payable by the Owner to the Vendor
on the same terms and subject to the limitations set forth in subsection 24.9(a)
above.

                              SECTION 25 SUSPENSION

         25.1 Owner's Right to Suspend Work. The Owner may, at any time and upon
reasonable notice to the Vendor, order the Vendor, in writing, to suspend all or
any part of the  Work  for  such  reasonable  period  of time as the  Owner  may
reasonably  determine to be appropriate for its convenience.  Any request by the
Vendor for a change in the  Specifications  caused by the Owner's  suspension of
the Work  pursuant  to this  subsection  25.1 will be  subject to the review and
reasonable  acceptance of the Owner. No modification to the Specifications  will
be made to the extent  that  performance  is, was or would have been  suspended,
delayed or  interrupted  for any other cause due to the Vendor's fault or if the
suspension  had no effect on agreed upon  performance  deadlines  and/or Project
Milestones set forth in this Contract. In the event of any such suspension,  the
Vendor  will be  compensated  for any actual  and  reasonable  loss,  actual and
reasonable damages or actual and reasonable  expenses arising directly from such
delay,  including but not limited to payments  contractually  required under any
Subcontractor  agreements and  reimbursement of reasonable  expenses  associated
with the necessary  re-deployment of the Vendor's  resources;  provided that the
Vendor will in such event use  reasonable  efforts to estimate and report to the
Owner any such costs or  expenses  prior to the  commencement  of any such Owner
suspension pursuant to this subsection 25.1.


                        SECTION 26 MOST FAVORED CUSTOMER

         26.1 Most Favored Customer  Status.  (a) With respect to the deployment
of the Initial  System  (including  any  Expansions  or additions to the Initial
System  within the context of the Initial  System  pursuant to the terms of this
Contract),  the Owner  will be deemed one of the  Vendor's  most  important  and
favored  Customers and will always receive priority in terms of availability and
quantity of Products,  Engineering and Services no less favorable than any other
Customer of the Vendor and in any event always in  accordance  with the terms of
this Contract, including, but not limited to, Exhibit A2. At any time during the
Term,  the Owner will receive PCS Products,  Engineering  and Services at prices
and on payment terms and all other contract terms, including financing terms, no
less  favorable to the Owner (when viewed  collectively)  than those  offered or
available to any other Customer (other than Initial Affiliates and/or Additional
Affiliates pursuant to the terms of this Contract) of the Vendor for use of such
Items  within  the  United  States  who  are  involved  in  transactions  and/or
arrangements of similar or lesser volumes (for the purposes hereof,  the Owner's
volume will always be deemed to be at least the level of the Initial  Commitment
plus any more PCS Products,  Services  and/or  Engineering  ordered at such time
during the Term of this Contract).

         (b) On an annual basis throughout the Term of this Contract  commencing
on the  Effective  Date the Vendor will be required to audit its offering of all
CDMA PCS Products,  engineering and services  provided to the  then-existing ten
(10) largest of its Customers (other than Initial  Affiliates  and/or Additional
Affiliates pursuant to the terms of this Contract) (based on volume purchased or
to be purchased)  in the  preceding  calendar year and certify to the Owner in a
certificate  executed  by a duly  authorized  officer  of the  Vendor  (the "MFC
Certificate") that the Owner has in fact received the prices,  payment and other
contract terms,  availability  and quantity of and on Products,  Engineering and
Services in accordance with the terms of clause (a) above.

         (c) To the extent the Owner determines pursuant to clause (b) above, or
otherwise, that the Vendor has not in fact complied with the terms of clause (a)
above the Owner will have  thirty  (30)  Business  Days from  receipt of the MFC
Certificate  to  provide  the Vendor  with a written  claim for  Product  and/or
Engineering  and/or  Service  pricing  rebates  on future  purchases  under this
Contract  based upon the  Owner's  reasonable  calculation  of the impact on the
Owner of the Vendor's failure to comply with clause (a) of this subsection 26.1.
The Owner's  written claim will specify the reasoning  underlying its claim.  To
the extent the Vendor  disagrees  with any such claim for such  pricing  rebates
made by the Owner  pursuant  to this  clause (c) the Vendor  will have the right
within ten (10) Business Days of receiving the Owner's  written  rebate claim to
request  management  escalation of the matter as provided in subsection 23.1. In
the event that the Parties have not resolved the matter within ten (10) Business
Days after commencement of such escalation,  either Party will have the right to
submit  the  Owner's  claim and the  Vendor's  written  response  thereto  to an
Independent  Auditor who will have the authority  only to determine  whether the
Vendor is in  non-compliance  with the terms of clause (a) above and whether the
Owner's  calculation  of the claimed  pricing  rebate is fair and  reasonable in
light of the  Vendor's  non-compliance  with the terms of clause (a) above.  Any
such independent  determination will be made upon specific  procedures and a set
of  factors  mutually  agreed by the  Parties.  The Vendor  will  provide to the
Independent  Auditor  records and summaries of its agreements with such ten (10)
largest  Customers  pursuant  to  and in  accordance  with  the  terms  of  this
subsection  26.1.  The  Independent  Auditor's  determination  must be made  and
delivered  to both the Vendor and the Owner  within  ten (10)  Business  Days of
receiving  the request from the Vendor.  The report of the  Independent  Auditor
will not be  determinative  of the Owner's  right to pricing  rebates under this
clause, and any dispute between the Vendor and the Owner as to such matter after
the Independent  Auditor has rendered its opinion may be referred to arbitration
as provided in subsection  23.2;  provided  that the report of such  Independent
Auditor  will be  admissible  as  evidence  in any such  arbitration.  The Party
requesting a determination  by an Independent  Auditor will bear the cost of the
auditor,  provided  that, if the other Party's  position is not supported by the
Independent Auditor, such other Party will bear any such cost.


                            SECTION 27 MISCELLANEOUS

         27.1 Amendments.  The terms and conditions of this Contract,  including
the provisions of Exhibits and Schedules hereto, may only be amended by mutually
agreed contract amendments.  Each amendment must be in writing and will identify
the  provisions  to be changed and the changes to be made.  Contract  amendments
must be signed by duly authorized  representatives of each of the Vendor and the
Owner.

         27.2 Owner  Liabilities.  The Parties understand and agree that none of
the Partners, nor any of their Affiliates, will guarantee or otherwise be in any
way liable with respect to any obligations or liabilities of the Owner or any of
its subsidiaries  pursuant to this Contract.  The Parties further understand and
agree that  neither  the Owner nor any of its  subsidiaries  will  guarantee  or
otherwise be in any way liable for any  obligations or liabilities of any of the
Partners or any  Affiliate of the Owner  pursuant to this Contract  unless,  and
only to the extent,  (i) the Owner or any one of its  subsidiaries in accordance
with the Owner's direction expressly agrees in writing to guarantee or otherwise
be  liable  for  such  liability,  or (ii) in the  case  of an  Affiliate,  such
Affiliate  orders  Products  and/or  Services  through the Owner pursuant to the
terms of this Contact.

         27.3 Offset.  The Vendor  hereby  waives any right of offset of amounts
owed by the Owner to the Vendor pursuant to the terms of this Contract.

         27.4 Assignment.  Except as otherwise  permitted  herein,  neither this
Contract  nor any portion  hereof may be assigned  by either  Party  without the
express prior written consent of the other Party provided that such consent will
not  otherwise  be  unreasonably  withheld  (provided  further  that the Owner's
reasonable concern about an assignee's ability to perform the obligations and/or
the Work of the  Vendor  pursuant  to and in  accordance  with the terms of this
Contract will be deemed to be reasonable  grounds for the Owner  withholding any
such consent).  The Owner may,  without the consent of the Vendor,  collaterally
assign its rights  hereunder  (including,  but not limited to, all licenses with
respect to the Software) to any or all parties providing  financing for any part
of the Nationwide Network under a collateral trust for the benefit of the Vendor
and  one or  more  other  entities  providing  financing  for  any  part  of the
Nationwide Network or similar  arrangement for the benefit of the Vendor and one
or  more  other  entities  providing  for  the  financing  for  any  part of the
Nationwide   Network,   in  either  case,  which  collateral  trust  or  similar
arrangement,  as the case may be,  is  reasonably  acceptable  to the  Vendor in
accordance with the terms of the financing documents. If requested by the Owner,
the Vendor will within seven (7) days of such request  provide a written consent
to any such assignment;  provided that such consent will permit  reassignment if
the  financing  parties  exercise  their  remedies  under the documents for such
financing subject to reasonable  standards as to (i) the creditworthiness of the
assignee and (ii) the fact that the assignee is not at such time a competitor of
the Vendor.  The foregoing  rights and  obligations are in addition to those set
forth in subsection 27.21. Any attempted assignment in violation of the terms of
this Contract will be null and void.

         27.5  Enforcement.  The Parties agree that either Party may enforce the
provisions of subsections  11.4 and 27.4  regarding  assignment by an action for
injunction or other equitable remedies.

         27.6  Notices.   Any  notice,   request,   consent,   waiver  or  other
communication required or permitted hereunder will be effective only if it is in
writing and  personally  delivered  by hand or by  overnight  courier or sent by
certified  or  registered  mail,  postage  prepaid,  return  receipt  requested,
addressed as follows:

THE MANNER SET FORTH IN SUCH  SUBSECTION  27.6.  NOTHING IN THIS SUBSECTION 27.7
WILL AFFECT THE RIGHT OF THE OWNER OR THE VENDOR TO SERVE  LEGAL  PROCESS IN ANY
OTHER MANNER PERMITTED BY LAW.

         27.8 Compliance with Law. The Owner and the Vendor will (a) comply with
all Applicable  Laws in the  performance of this  Contract,  including,  without
limitation, the laws and regulations of the United States Department of Commerce
and State Department and any other applicable agency or department of the United
States  regarding  the import,  re-import,  export or  re-export  of products or
technology;  and (b)  indemnify  each other for any loss,  liability  or expense
incurred as the result of breach of this subsection 27.8.

         27.9 Independent Contractor. All work performed by any Party under this
Contract will be performed as an  independent  contractor and not as an agent of
the other and no Persons  furnished by the  performing  Party will be considered
the employees or agents of the other.  The performing  Party will be responsible
for its  employees'  compliance  with all laws,  rules,  and  regulations  while
performing all work under this Contract.

         27.10  Headings.  The headings  given to the  Sections and  subsections
herein are inserted  only for  convenience  and are in no way to be construed as
part of this Contract or as a limitation of the scope of the particular  Section
or subsection to which the title refers.

         27.11 Severability.  Whenever possible, each provision of this Contract
will be  interpreted  in such a manner as to be  effective  and valid under such
applicable  law,  but,  if any  provision  of this  Contract  will be held to be
prohibited  or invalid in any  jurisdiction,  the  remaining  provisions of this
Contract  will  remain in full force and effect and such  prohibited  or invalid
provision  will  remain  in  effect  in  any  jurisdiction  in  which  it is not
prohibited or invalid.

         27.12 Waiver.  Unless otherwise  specifically  provided by the terms of
this Contract, no delay or failure to exercise a right resulting from any breach
of this  Contract  will  impair such right or will be  construed  to be a waiver
thereof,  but such  right  may be  exercised  from time to time as may be deemed
expedient.  If any  representation,  warranty  or  covenant  contained  in  this
Contract is breached by either Party and  thereafter  waived by the other Party,
such waiver will be limited to the particular breach so waived and not be deemed
to waive any other breach under this Contract.

         27.13 Public  Statements  and  Advertising.  (a) Neither  Party nor its
Subcontractors  will issue any public statement (or any private statement unless
required in the performance of the Work), except as stated below, relating to or
in any way disclosing any aspect of the Work, the System,  any PCS System or any
PCS Sub-System including the scope, the specific terms of this Contract,  extent
or value of the Work and/or the System or any PCS System or any PCS  Sub-System.
Express  written  consent of the other Party is required prior to the invitation
of or  permission  to any reporter or journalist to enter upon the System or any
part  thereof.  The  Vendor  agrees  not  to  use  for  publicity  purposes  any
photographs,  drawings and/or materials describing the System, any PCS System or
any PCS  Sub-System  without  obtaining the prior written  consent of the Owner,
which consent will not be unreasonably withheld. This subsection 27.13(a) is not
intended  to exclude the  provision  of  necessary  information  to  prospective
Subcontractors and the Vendor's or the Owner's personnel, agents or consultants.
All other such public  disclosures by a Party require the written consent of the
other Party.  The obligations of the Parties under this subsection  27.13(a) are
in addition to their respective  obligations  pursuant to subsection 27.19. This
subsection  27.13(a)  will in no way  limit  either  Party  from  responding  to
customary press inquiries or otherwise  making public or private  statements not
otherwise  disclosing  Proprietary  Information  or the  specific  terms of this
Contract in the normal course of its business and/or in connection with the Work
hereunder.

         (b) Subject to the last  sentence of  subsection  27.13(a),  each Party
will submit to the other proposed copies of all  advertising  (other than public
statements or press releases) wherein the name, trademark or service mark of the
other Party or its Affiliates or affiliates is mentioned; and neither Party will
publish  or use  such  advertising  without  the  other  Party's  prior  written
approval.  Such approval will be granted as promptly as possible and will not be
unreasonably  withheld.  The Parties  acknowledge  that the  obtaining  of prior
written  approval for each such use pursuant to this subsection  27.13(b) may be
an  administrative  burden.  At the request of either  Party,  the Owner and the
Vendor  will  establish  mutually  acceptable  guidelines  that will  constitute
pre-authorization  for the  uses  specified  therein.  Such  guidelines  will be
subject to change from time to time at the reasonable request of either Party.

         27.14   Records   and   Communications.   To  the  extent  not  already
established,  promptly  after  the  Work  begins,  procedures  for  keeping  and
distributing  orderly and complete  records of the Work and its progress will be
established.  The  procedures so  established  will be followed  throughout  the
course of the Work unless the Owner and the Vendor  mutually agree in advance in
writing to revise the procedures.  Furthermore,  immediately after the Notice to
Proceed is issued,  complete  procedures for communications  among the Owner and
the Vendor will be established.  The procedures so established  will be followed
throughout the course of the Work unless the Owner and the Vendor mutually agree
in advance and in writing to revise such procedure.

         27.15  Ownership  of   Specifications.   Neither  the  Vendor  nor  any
Subcontractor,  nor any other Person performing or furnishing the Work,  whether
or not under a direct or indirect  contract with the Owner, will have or acquire
any title to or ownership rights in any of the  Specifications,  or in any other
part or portion of this Contract (or copies of any of the Specifications or this
Contract);  and no such  Person will reuse any of the  Specifications  on and/or
with  respect to any other  project  without  the prior  written  consent of the
Owner.  The  Specifications  and this Contract (and any and all copies thereof),
are owned by and title resides in the Owner, unless otherwise agreed between the
Owner and any other Person.  Notwithstanding  anything  contained  herein to the
contrary,  the Owner will not  acquire  any patent,  copyright  or trade  secret
rights as a result of this Contract,  except with respect to copyright and trade
secret rights  pursuant to licenses and other  approvals  provided in connection
with the  performance of the Work and except to the extent that a  non-exclusive
license of any of the Vendor's  copyright or trade secret  rights is required to
perform the Work.

         27.16 Financing Parties Requirements.  The Vendor acknowledges that the
Owner represents that attainment of financing for construction of the Nationwide
Network may be subject to conditions  that are customary and appropriate for the
providers of such financing.  Therefore,  the Vendor agrees to execute  promptly
any  reasonable  amendment to or  modification  or  assignment  of this Contract
required  by  such  providers  (including,  without  limitation,  any  pertinent
industrial  development  authority or other similar  governmental agency issuing
bonds for financing of the System) which do not  materially  modify the scope of
the Vendor's Work in order to obtain such financing.  In the event that any such
amendment  or  modification  materially  increases  the  Vendor's  risk or costs
hereunder,  the Owner and the Vendor will  negotiate in good faith to adjust the
Contract Price,  and to equitably adjust such other provisions of this Contract,
if any, which may be affected  thereby,  to the extent necessary to reflect such
increased  risk or costs.  In no event will the Vendor be required to accept any
modification  or  amendment  pursuant  to this  subsection  27.16  which  places
material increased risk on the Vendor or otherwise materially modifies the scope
of the Vendor's Work, if, in the Vendor's  reasonable  opinion,  such materially
increased risk or material  modification in the Work is not otherwise adequately
addressed by the Owner or otherwise.  The Vendor will be responsible for and pay
all costs as a result of the Vendor's  unreasonable  refusal to promptly  comply
with the request for any such  modification or amendment made by any provider of
financing described in this subsection 27.16.

         27.17 Owner Review,  Comment and  Approval.  To the extent that various
provisions of this Contract provide for the Owner's review, comment, inspection,
evaluation,  recommendation  or  approval,  the Owner may at its option do so in
conjunction  and/or  consultation  with the  Vendor.  To the  extent  that  this
Contract requires the Owner to submit, furnish, provide or deliver to the Vendor
any report,  notice,  Change Order, request or other items, the Owner may at its
option and upon written  notice to the Vendor  designate the Engineer to submit,
furnish,  provide or deliver such items as the Owner's  agent  therefor.  To the
extent that  various  provisions  of this  Contract  provide  that the Owner may
order,  direct or make  requests with respect to  performance  of the Work or is
provided  access to the  System  sites or any other  site,  the Owner may at its
option and upon written  notice to the Vendor  authorize  the Engineer to act as
the Owner's  agent  therefor.  Upon receipt of such  notice,  the Vendor will be
entitled to rely upon such authorization until a superseding written notice from
the Owner is received by the Vendor.

         27.18  Specifications.   The  Owner  acknowledges  that  parts  of  the
Specifications  are comprised of Specifications  prepared by the Vendor and that
the Vendor contributed  significantly to many other portions thereof.  The Owner
also  acknowledges  that,  during the normal design,  evolution and  development
process,  portions of the  Specifications  may appear in design and  procurement
documents  prepared by the Vendor in its normal  course of  business;  provided,
however,  that the Owner will have no liability for any third party infringement
claims  arising from such  Specifications  prepared by the Vendor and the Vendor
will hold the Owner  harmless  from any such third  party  claims as provided in
subsection 14.2.

         27.19   Confidentiality.   (a)  All  information,   including   without
limitation  all oral and  written  information  (including,  but not limited to,
determinations or reports by arbitrators or the Third Party Engineer pursuant to
the  terms of this  Contract),  disclosed  to the  other  Party is  deemed to be
confidential,  restricted and proprietary to the disclosing  Party  (hereinafter
referred  to as  "Proprietary  Information").  Each  Party  agrees  to  use  the
Proprietary  Information  received  from the other Party only for the purpose of
this  Contract.  Except as  specified in this  Contract,  no other  rights,  and
particularly licenses, to trademarks,  inventions,  copyrights,  patents, or any
other intellectual property rights are implied or granted under this Contract or
by the conveying of  Proprietary  Information  between the Parties.  Proprietary
Information  supplied is not to be  reproduced in any form except as required to
accomplish  the intent of, and in accordance  with the terms of, this  Contract.
The  receiving  Party  must  provide  the  same  care  to  avoid  disclosure  or
unauthorized  use of  Proprietary  Information as it provides to protect its own
similar proprietary information but in no event will the receiving Party fail to
use reasonable care under the  circumstances to avoid disclosure or unauthorized
use of Proprietary Information.  All Proprietary Information must be retained by
the  receiving  Party in a secure place with access  limited to only such of the
receiving  Party's  employees,  subcontractors  or agents  who need to know such
information  for  purposes  of this  Contract  and to such third  parties as the
disclosing  Party has consented to by prior written  approval.  All  Proprietary
Information,  unless otherwise  specified in writing (i) remains the property of
the  disclosing  Party,  (ii) must be used by the  receiving  Party only for the
purpose  for which it was  intended,  and (iii)  such  Proprietary  Information,
including  all copies of such  information,  must be returned to the  disclosing
Party or destroyed  after the receiving  Party's need for it has expired or upon
request of the disclosing  Party,  and, in any event,  upon  termination of this
Contract.  At the request of the  disclosing  Party,  the  receiving  Party will
furnish a  certificate  of an officer of the  receiving  Party  certifying  that
Proprietary Information not returned to disclosing Party has been destroyed. For
the purposes hereof, Proprietary Information does not include information which:

                                    (i)  is  published  or is  otherwise  in the
                           public domain through no fault of the receiving Party
                           at the time of any claimed disclosure or unauthorized
                           use by the receiving Party;

                                    (ii) prior to  disclosure  pursuant  to this
                           Contract is properly within the legitimate possession
                           of the  receiving  Party as evidenced  by  reasonable
                           documentation to the extent applicable;

                                    (iii)  subsequent to disclosure  pursuant to
                           this Contract is lawfully received from a third party
                           having rights in the information  without restriction
                           of  the  third  party's  right  to  disseminate   the
                           information  and  without  notice of any  restriction
                           against its further disclosure;

                                    (iv)  is  independently   developed  by  the
                           receiving  Party  or is  otherwise  received  through
                           parties  who  have  not  had,   either   directly  or
                           indirectly,   access   to  or   knowledge   of   such
                           Proprietary Information;

                                    (v) is  transmitted  to the receiving  Party
                           after  the  disclosing  Party  has  received  written
                           notice from the receiving Party after  termination or
                           expiration  of this  Contract that it does not desire
                           to receive further Proprietary Information;

                                    (vi) is obligated to be produced under order
                           of a court of competent jurisdiction or other similar
                           requirement of a Governmental  Entity, so long as the
                           Party required to disclose the  information  provides
                           the other  Party with  prior  notice of such order or
                           requirement   and  its   cooperation  to  the  extent
                           reasonable in preserving its confidentiality; or

                                    (vii)  the disclosing Party agrees in writ-
                           ing is free of such restrictions.

         (b) Because  damages may be difficult to ascertain,  the Parties agree,
without limiting any other rights and remedies  specified  herein, an injunction
may be sought  against the Party who has breached or  threatened  to breach this
subsection  27.19.  Each Party  represents and warrants that it has the right to
disclose all Proprietary  Information  which it has disclosed to the other Party
pursuant to this Contract,  and each Party agrees to indemnify and hold harmless
the other from all claims by a third party related to the wrongful disclosure of
such third party's proprietary information.  Otherwise,  neither Party makes any
representation or warranty,  express or implied, with respect to any Proprietary
Information.

         27.20  Entirety of  Contract;  No Oral  Change.  This  Contract and the
Exhibits and Schedules  referenced herein constitute the entire contract between
the Parties  with  respect to the  subject  matter  hereof,  and  supersede  all
proposals,   oral  or  written,  all  previous   negotiations,   and  all  other
communications between the Parties with respect to the subject matter hereof. No
modifications, alterations or waivers of any provisions herein contained will be
binding  on the  Parties  hereto  unless  evidenced  in  writing  signed by duly
authorized  representatives of both Parties as set forth in subsection 27.1. Any
representations  by the  Vendor in any RFP  response  and/or  any  documentation
otherwise provided to the Owner in connection with the Vendor's  solicitation of
the business  granted pursuant hereto prior to the execution hereof will also be
deemed  to be  incorporated  into and  otherwise  made a part of this  Contract;
provided  that any such  information  will in no way be  deemed  to  modify  the
Specifications unless otherwise specifically mutually agreed by the Parties.

         27.21 Successors and Assigns.  This Contract will bind and inure to the
benefit of the Parties to this Contract, their successors and permitted assigns.

         27.22 Change of Control of the Vendor.  The Vendor will not consolidate
with or merge  into  any  other  Person  or  convey,  transfer  or lease  all or
substantially all of its assets to any Person,  nor will any Person or group (as
such term is defined in the  Securities  Exchange  Act of 1934,  as amended (the
"Exchange Act")) own or acquire fifty percent (50%) of the value of the Vendor's
equity where such Person or group did not own as of the Effective Date in excess
of ten  percent  (10%) of such equity (any such Person or group will be referred
to as the "Vendor's Succeeding Entity"), unless:

                                    (i)  the Vendor's Succeeding Entity will
                           agree to assume the obligations of the Vendor under
                           this Contract; and

                                    (ii)  the  Owner  will  have   approved  the
                           transaction, based solely on (i) the creditworthiness
                           of the Vendor's  Succeeding Entity,  (ii) whether the
                           Vendor's  Succeeding  Entity is a  competitor  of the
                           Owner and (iii)  whether  in the  Owner's  reasonable
                           judgment the Vendor's  Succeeding Entity will be able
                           to fulfill  the  obligations  for  present and future
                           orders under this Contract.

         27.23 Change of Control of the Owner.  Except as otherwise (i) provided
below,  (ii)  permitted  under the  documents  relating to the  financing of the
Nationwide  Network or (iii) pursuant to internal  reorganizations of the Owner,
the Owner will not  consolidate  with or merge into any other business entity or
convey,  transfer or lease all or substantially all of its assets to any Person,
nor will any Person or group (as such term is defined in the  Exchange  Act) own
or acquire fifty percent (50%) of the value of the Owner's  limited  partnership
interests or general  partnership  interests  where such Person or group did not
own as of the  Effective  Date in excess of ten percent  (10%) of either of such
partnership  interests  (any such  Person or group  will be  referred  to as the
"Owner's Succeeding Entity"), unless:

         (a)  the Owner's Succeeding Entity will agree to assume the obligations
of the Owner under this Contract; and

         (b) the Vendor will have approved the transaction,  based solely on (i)
the  creditworthiness  of the  Owner's  Succeeding  Entity and (ii)  whether the
Owner's Succeeding Entity is a competitor of the Vendor.

         Notwithstanding  anything  stated  in  this  subsection  27.23  to  the
contrary a "Permitted  Transaction" or a series of Permitted Transactions by any
Partner or Partners (or any affiliate, parent or subsidiary thereof) will not be
subject to or in any way in violation of this subsection 27.23. For the purposes
hereof,  a  "Permitted  Transaction"  means  with  respect  to any  Partner  (or
affiliate,  parent or  subsidiary  thereof) a  transaction  or series of related
transactions  in which (i) such Partner  ceases to be a subsidiary of its parent
or such parent  transfers  its interests in such Partner to a Person that is not
an  affiliate  of such  Partner and (ii) the new parent of such Partner (or such
Partner  if it is its  own  parent)  or the  parent  of the  transferee  of such
interests after giving effect to such transaction,  or the last transaction in a
series of related  transactions,  owns,  directly  and  indirectly  through  its
affiliates, all or a "Substantial Portion" of the cable television system assets
(in the case of a Partner in the cable  business  (a "Cable  Partner"))  or long
distance telecommunications business assets (in the case of Sprint) owned by the
parent  of such  Partners,  directly  and  indirectly  through  its  affiliates,
immediately  prior  to  the  commencement  of  such  transaction  or  series  of
transactions.  As used herein,  "Substantial Portion" means (x) in the case of a
Cable Partner,  cable  television  systems serving seventy five percent (75%) or
more of the aggregate  number of basic  subscribers  served by cable  television
systems in the United States  (including its territories  and possessions  other
than  Puerto  Rico)  owned by the parent of such  Cable  Partner,  directly  and
indirectly through its affiliates,  and (y) in the case of Sprint, long distance
telecommunications business assets serving seventy five percent (75%) or more of
the aggregate number of customers served by the long distance telecommunications
business in the United States  (including its territories and possessions  other
than Puerto Rico) owned by Sprint  and/or its parent,  directly  and  indirectly
through its affiliates.

         27.24 Relationship of the Parties. Pursuant to subsection 27.9, nothing
in this Contract will be deemed to constitute  either Party a partner,  agent or
legal representative of the other Party, or to create any fiduciary relationship
between the Parties. The Vendor is and will remain an independent  contractor in
the performance of this Contract, maintaining complete control of its personnel,
workers,  Subcontractors  and operations  required for  performance of the Work.
This Contract will not be construed to create any  relationship,  contractual or
otherwise, between the Owner and any Subcontractor.

         27.25  Discretion.  Notwithstanding  anything  contained  herein to the
contrary,  to the extent that various  provisions  of this  Contract call for an
exercise of  discretion in making  decisions or granting  approvals or consents,
the Parties will be required to exercise such discretion,  decision or approvals
in accordance with accepted PCS industry practices and in good faith.

         27.26  Non-Recourse.  No past,  present  or future  limited  or general
partner  in or of the  Owner,  no  parent  or  other  affiliate  of any  company
comprising the Owner, and no officer, employee,  servant,  executive,  director,
agent or authorized representative of any of them (each, an "Operative") will be
liable by virtue of the direct or indirect  ownership interest of such Operative
in the Owner for payments due under this Contract or for the  performance of any
obligation,  or  breach  of any  representation  or  warranty  made by the Owner
hereunder.  The sole recourse of the Vendor for  satisfaction of the obligations
of the Owner  under  this  Contract  will be against  the Owner and the  Owner's
assets and not  against  any  Operative  or any assets or  property  of any such
Operative.  In  the  event  that  a  default  occurs  in  connection  with  such
obligations,  no action will be brought  against any such Operative by virtue of
its direct or indirect ownership interest in the Owner. The foregoing provisions
of this  subsection  27.26  will not in any way limit or  restrict  any right or
remedy of the Vendor with  respect  to, and the  Operatives  will  remain  fully
liable for, any fraud perpetuated by such Operatives.

         27.27  Improvements,  Inventions  and  Innovations.  All  rights in any
improvements,  inventions,  and  innovations  made by the Owner will vest in the
Owner,  and the Owner and its  affiliates  will have the right to  exploit  such
improvements,  inventions,  and  innovations.  All  rights in any  improvements,
inventions and innovations  made by the Vendor will vest in the Vendor,  and the
Vendor  and its  affiliates  will have the right to exploit  such  improvements,
inventions and innovations; provided, however, that subject to and in accordance
with  subsection 11.9 the Owner and its affiliates may be granted certain rights
to  improvements,  inventions or innovations  made in connection with the System
pursuant to subsection 11.9 by the Vendor (but not by any  Subcontractor) in the
course and as a result of  performing  the Work and in which the Vendor  owns or
possesses any  proprietary  interest  (provided that the  immediately  preceding
proviso  of this  last  sentence  of this  subsection  27.27 is not  subject  to
subsection 23.2).

         27.28  Attachments  and  Incorporations.  All  Schedules  and  Exhibits
attached hereto, are hereby  incorporated by reference herein and made a part of
this  Contract  with the same  force and  effect  as  though  set forth in their
entirety herein.

         27.29 Conflicts.  In the event of any conflict or  inconsistency  among
the  provisions  of  this  Contract  and  the  documents   attached  hereto  and
incorporated  herein,  such conflict or inconsistency will be resolved by giving
precedence  to this  Contract and  thereafter  to the  Exhibits,  Schedules  and
Specifications.

         27.30 Counterparts. This Contract may be executed by one or more of the
Parties to this Contract on any number of separate counterparts, and all of said
counterparts  taken  together  will be  deemed  to  constitute  one and the same
instrument.

                                   Insurance

         The Vendor will procure and maintain, during the Term of this Contract,
insurance with financially sound and reputable  insurance  companies in not less
than the following amounts:

         (a) Workers'  compensation  insurance in accordance with the provisions
of the applicable  Worker's  Compensation  or similar law of each state or other
political subdivision with jurisdiction applicable to the Vendor's personnel;

         (b)  Commercial  general  liability,  including  contractual  liability
insurance  with  a  coverage  limit  of  not  less  than  five  million  dollars
($5,000,000)  combined  single limit per occurrence of bodily injury or property
damage liability. To the extent reasonably requested by the Owner and not unduly
burdensome to the Vendor and to the extent otherwise applicable,  such policy or
policies  will  name the  Owner as an  additional  insured  and will  contain  a
provision  waiving the insurer's right of subrogation  against the Owner and its
employees, agents, officers and directors; and

         (c) If the use of any vehicle is required by the Vendor or any employee
of the Vendor in the  performance of this Contract,  the Vendor will also obtain
and maintain  business  vehicle  liability  insurance  for the  operation of all
owned,  non-owned and hired  vehicles with a coverage limit of not less than one
million  dollars  ($1,000,000)  per accident for bodily injury and not less than
three  hundred  thousand  dollars  ($300,000)  per accident for property  damage
liability.

         The  Vendor  reserves  the  right to  self-retain  any or all  coverage
described above in this Schedule 6 and upon the Effective Date, does retain some
of such coverage.  The Vendor upon the written request of the Owner will deliver
to the Owner  certificates  of  commercial  insurance  satisfactory  in form and
content  to the Owner  evidencing  that all of the  insurance  required  by this
Contract is in force,  and that no policy may be canceled or materially  altered
without first giving the Owner at least thirty (30) days' written notice.

         Nothing herein is intended to imply that the Vendor's  liability to the
Owner is limited to the amount of insurance carried.

                                  Schedule 11

                           Order Cancellation Charges

Without  charge and/or  penalty,  the Owner may cancel any Order for Products no
later than ninety (90) days prior to the earliest date scheduled for shipment of
such Product; or

If the Owner  cancels an Order less than ninety (90) days prior to the  earliest
date scheduled for shipment of such Product,  the Owner will pay to the Vendor a
cancellation  charge  of ten  percent  (10%) of the price  for such  Product  as
determined pursuant to the Contract; or

If the Owner  cancels an Order  less than sixty (60) days prior to the  earliest
date scheduled for shipment of such Product,  the Owner will pay to the Vendor a
cancellation  charge of fifteen  percent  (15%) of the price for such Product as
determined pursuant to the Contract; or

date scheduled for shipment of such Product,  the Owner will pay to the Vendor a
cancellation  charge of twenty  percent  (20%) of the price for such  Product as
determined pursuant to the Contract.

The  Owner may not  cancel an Order  after the  applicable  date  scheduled  for
shipment of such Product.  The payment of such charges will be the Vendor's sole
remedy and the Owner's sole  obligation  for such  canceled  Order.  Any changes
requested  by the Owner that  involve the return or  exchange  of  Non-Essential
Equipment   will  be  subject  to  the  standard   policies  of  the  applicable
Non-Essential  Equipment  supplier unless such policies are otherwise set out in
the applicable  agreement between such Non-Essential  Equipment supplier and the
Vendor,  in which case the Owner will be  entitled  to cancel any such Order for
Non-Essential Equipment in accordance with the terms of such agreement.  For the
purposes  of this  Schedule  11, the term  "Order"  will not include the Minimum
Commitment or the Initial Commitment.

Nothing herein will be deemed to bar the Vendor's right to invoice the Owner for
all Services  actually  performed  prior to the date of such  performance by the
Vendor in respect of such  Products in  accordance  with the  provisions of this
Contract.

         subsection 2.7(c) or any 97 System, any Interim Delay Penalties accrued
         pursuant to  subsection  15.2(a) will be credited back to the Vendor in
         the manner  described  in the  immediately  preceding  sentence  to the
         extent that (i) the Vendor successfully achieves Substantial Completion
         of such PCS  System  or PCS  Sub-System  on or  before  the  Guaranteed
         Substantial  Completion  Date (as such date is determined in accordance
         with the terms of  subsection  2.7(c))  and (ii) the  relevant  interim
         delay does not otherwise  materially  adversely affect the Owner,  such
         PCS System or PCS Sub-System and/or the System as a whole."

     5.  NO  OTHER  AMENDMENTS.   EXCEPT  AS  EXPRESSLY  AMENDED,  MODIFIED  AND
SUPPLEMENTED  HEREBY, THE PROVISIONS OF THE CONTRACT ARE AND WILL REMAIN IN FULL
FORCE AND EFFECT AND NOTHING IN THIS  AMENDMENT WILL BE CONSTRUED AS A WAIVER OF
ANY OF THE RIGHTS OR OBLIGATIONS OF THE PARTIES UNDER THE CONTRACT.

     6. GOVERNING  LAW. THIS AMENDMENT WILL BE CONSTRUED IN ACCORDANCE  WITH AND
GOVERNED  BY THE LAWS OF THE STATE OF NEW YORK  WITHOUT  REGARDS TO THE LAWS AND

Amendment  to be signed by their  duly  authorized  representatives  on the date
first above written.

         any Purchase  Order shall be deemed to render any such  Purchase  Order
         acknowledged.  To the extent that the Vendor is actually aware that any
         Purchase  Order  in  any  way   contradicts  or  is  not  otherwise  in
         conformance  with the  terms of this  Contract,  the  Vendor  agrees to
         promptly notify the Owner of any such  contradiction or non-conformance
         as soon as possible upon becoming actually aware of such  contradiction
         or non-conformance so that the Owner will have a reasonable opportunity
         to correct any such contradiction or non-conformance and,  furthermore,
         to the  extent  reasonable  under the  circumstances  the  Vendor  will
         endeavor to fulfill any such non-conforming Purchase Order ignoring any
         such  non-conformity  unless the  Owner,  after  notification  from the
         Vendor,  will have expressly  refused to accept the fulfillment of such
         Purchase Order with any such correcting modification.

                  (b) Except with  respect to the first  Forecast  (and the next
         succeeding Forecast  immediately  following the first Forecast),  in no
         event will the Vendor be required to

<PAGE>


                  accept an amount in any  given  month of a  Forecast  which is
         greater than one hundred  -fifty  percent  (150%) of the average amount
         forecasted by the Owner for the three months immediately  preceding the
         subject month.

                  (c) The  Vendor  will  reasonably  cooperate  with the  Owner,
         and/or  any Person  designated  by the Owner for such  purpose,  (i) to
         utilize UPC stock control  numbering and other bar-coding  requirements
         relating  to  inventory  processes  and  systems,  and (ii) to  develop
         processes and systems that will  maximize  delivery  logistics.  Metric
         targets  will be  defined by the mutual  good  faith  agreement  of the
         Parties for acceptable stock out percentages,  delivery times and total
         logistics costs.

                  (d) Unless the Parties  otherwise  expressly agree in writing,
         each Purchase  Order will be deemed to  incorporate by reference all of
         the terms and  conditions  of this  Contract.  Should  the terms of any
         Purchase Order  conflict with the terms of this Contract,  the terms of
         this Contract will govern unless the Parties expressly agree in writing
         (signed by a duly  authorized  representative  of both  Parties) to the
         contrary.  This  Contract  will  continue to apply to a Purchase  Order
         pursuant to the terms of this Contract until all obligations herein and
         thereunder are performed.

                  7.7 Cancellation of Additional  Products and Services.  During
         the Term, the Owner will have the right, but not the obligation, at any
         time to cancel,  in whole or in part,  any  Purchase  Order  respecting
         Additional  Products  and Services  made  pursuant to the terms of this
         Contract upon advance  written notice to the Vendor.  In the event of a
         cancellation  permitted  hereunder,  the Owner  will pay to the  Vendor
         order  cancellation  charges in accordance  with,  and pursuant to, the
         terms of Schedule 11A.

                  7.8  Delivery  of  Additional  Products.   All  deliveries  of
         Additional Products will be made to the FOB Point and/or the Designated
         Switch Site, as the case may be, at the Vendor's sole cost and expense.
         The Owner may request that the Vendor provide more extensive logistical
         and  distribution  capabilities to the Owner,  which  capabilities  the
         Vendor will use its best commercial  efforts to provide.  If the Vendor
         agrees to provide such services,  there may be,  depending on the level
         and scope of such  services,  additional  charges to the Owner on a per
         Additional Product basis. Any such charges will be mutually agreed upon
         by the Parties during negotiations between the Parties on the provision
         of any such  additional  logistical and  distribution  services  beyond
         those outlined in this subsection.

                  7.9  Purchase  Order  Deferral.  The Owner may defer  (without
         payment or penalty of any kind whatsoever) upon written notice provided
         to the Vendor at least  thirty  (30) days prior to the actual  shipment
         therefor,  all of or any portion of any then outstanding Purchase Order
         (on a one time basis only with  respect to each  Purchase  Order) for a
         period not less than  thirty  (30) days and not in excess of sixty (60)
         days beyond the date originally  scheduled for the delivery  thereof by
         the Vendor; provided that in no event will

<PAGE>


                  the Owner be entitled hereunder to defer shipment of more than
         fifty (50) BTSs and/or Growth Cabinets,  as the case may be, at any one
         time.

         7.    Amendments to Section 8.

               Subsection  8.1 is hereby  amended  by  making  it 8.1(a)  and by
adding the following as 8.1(b) immediately thereafter:

                  "(b) The  Vendor  will  Install  and  Integrate  those BTS and
         Growth  Cabinet  Additional  Products  for  which  Optional  Additional
         Services  are  ordered by the Owner,  pursuant to the  requirements  of
         Exhibit  B4. The Owner will be  responsible  for the  Installation  and
         Integration of all other BTS and Growth Cabinet Additional Products for
         which such Optional  Additional  Services are not ordered by the Owner.
         The  Vendor  will  be  responsible   for  and  will  perform  the  full
         Installation  and Integration of MSC Additional  Products in accordance
         with Exhibit B4."

         8.     Amendments to Section 9.

               (a)  Subsection  9.1 is hereby  amended  by making it  subsection
9.1(a) and adding the following subsection 9.1(b) immediately thereafter:

                  "(b)  Notwithstanding  anything contained in subsection 9.1(a)
         above  to the  contrary,  the  Vendor  must  carry  out the  Additional
         Services  Acceptance  Tests on  Additional  Products  and  Services  as
         specified in the Testing Exhibits."

               (b)  Subsection  9.2 is  hereby  amended  by  deleting  it in its
entirety and replacing it with the following subsection 9.2:

                  "9.2 Costs and Expenses.  The costs and expenses of Acceptance
         Tests will be borne by the Vendor, and the Owner will not be charged or
         invoiced for such costs and expenses. If the Acceptance Tests performed
         by the  Vendor  on  each  Product  and  Service  are not  satisfied  in
         accordance  with the  relevant  requirements  of Exhibit B3,  Exhibit F
         and/or  the  Testing  Exhibits,  as the case may be,  or are  otherwise
         inconclusive  in the reasonable  judgment of the Owner,  the Owner will
         have the right to order further  Acceptance  Tests at the sole cost and
         expense of the Vendor."

         9.     Amendments to Section 12.

               (a)  Subsection  12.1 is hereby  amended by making it  subsection
12.1(a) and adding the following subsection 12.1(b) immediately after subsection
12.1(a):

               "(b) Notwithstanding  anything contained in subsection 12.1(a) to
               the contrary, the Vendor understands and agrees that the Software
               release  management  requirements  set  forth  in  Exhibit  J are
               material  to the  operation  of  the  System  and to the  Owner's
               business. The Vendor will provide all Software Upgrades, Software
               Enhancements and

<PAGE>


                  Software  Combined Releases pursuant to and in accordance with
         the  requirements set forth in Exhibits C, C1 and J. Without in any way
         limiting the foregoing, Software Upgrades must be provided to the Owner
         by the  Vendor at no charge  (other  than the  Owner's  payment  of the
         Annual Release  Maintenance Fees pursuant to subsection 12.1(a)) to the
         Owner for the entire Term of this Contract.  In the event the Vendor at
         any time  issues a  Software  Combined  Release to such  Software,  the
         Software  Combined  Release will be provided at the prices for Software
         features  set forth on  Schedule  2A. The Vendor will at all times take
         all  reasonable  measures to ensure that the Products and Services will
         not introduce or release any virus or other software  contaminant  into
         any part of the Nationwide Network."

               (b)  Subsection  12.3 is hereby  amended  by  deleting  it in its
entirety and replacing it with the following subsections 12.3(a) and (b):

               "12.3 Software  Installation,  Testing and  Maintenance.  (a) The
               installation and testing of the Software  associated with Initial
               Products  by the Vendor and the  acceptance  thereof by the Owner
               will be  performed in  accordance  with the criteria set forth in
               Exhibit B3.

                  (b)  Subject to clause (c) below and  subsection  12.3.1,  the
         installation  and testing of the Software  associated  with  Additional
         Products by the Vendor and the acceptance  thereof by the Owner will be
         performed   in   accordance   with  the   criteria   of  the   relevant
         Specifications  including,  but not  limited to, the  requirements  set
         forth in Exhibits B3, B4, C, C1 and J.

                  (c) Notwithstanding anything contained herein to the contrary,
         the Optional  Features  Software Releases and the WIN Software Releases
         will, to the extent  applicable,  conform to the requirements set forth
         in  Exhibits C and C1. The  installation  and  testing of the  Optional

         Release and each WIN  Software  Release by the Owner will be subject to
         the terms of subsection 12.3.1."

               (c) Section 12 is hereby further  amended by adding the following
subsection 12.3.1 immediately after subsection 12.3:

                  "12.3.1 Optional  Features  Software Releases and WIN Software
         Releases Acceptance. (a) The Owner and the Vendor agree that acceptance
         testing for each Optional Features Software Release and/or WIN Software
         Release,  as the  case may be,  will  commence  no later  than ten (10)
         Business  Days after the Vendor's  delivery of such  Optional  Features
         Software  Release or WIN Software  Release,  as the case may be, to the
         Owner's Test-bed Laboratory in accordance with Exhibit C and/or C1. The
         Vendor  will  install  all  such  Optional  Features  Releases  and WIN
         Software Releases into the Owner's Test-Bed Laboratory on the dates set
         forth in Exhibit C and/or C1 for each such Optional

<PAGE>


                  Features  Software  Release  and  WIN  Software  Release,   as
         applicable.   The  period  for  acceptance  testing  pursuant  to  this
         subsection  12.3.1  will run for no  longer  than the  thirty  (30) day
         period after commencement of acceptance testing.  The Owner will accept
         or reject each such Optional  Features Software Release or WIN Software
         Release,  as the case may be, within such thirty (30) day period unless
         the Parties mutually agree that the Optional  Features Software Release
         or WIN  Software  Release,  as the case may be, has met the  acceptance
         tests  prior  thereto.  If the  Owner  does not  provide  a  notice  of
         rejection,  then the  Optional  Features  Software  Release  or the WIN
         Software  Release,  as the case may be,  will be  deemed  to have  been
         accepted at the end of the thirty (30) day acceptance period;  provided
         that any such acceptance will in no way limit the Vendor's  warranty or
         any other obligations under the Contract. If prior to Owner acceptance,
         the Owner notifies the Vendor of a Defect or Deficiency in the Optional
         Features Software Release or the WIN Software Release,  as the case may
         be,  then  the  thirty  (30) day  acceptance  period  will be  extended
         day-for-day until the Vendor has corrected such Defect or Deficiency.

                  (b)  Minor   defects  and   deficiencies   not  affecting  the
         operational use of any part of such Optional  Features Software Release
         or WIN  Software  Release,  as the case may be,  shall not give rise to
         withholding  acceptance,  provided that the Vendor undertakes to remedy
         such defects and shortcomings as soon as reasonably possible."

               (d)  Subsection  12.4 is hereby  amended  by  deleting  it in its
entirety and replacing it with the following subsection 12.4:

                  "12.4 Software Fixes. In the event that any Software  Upgrade,
         Software  Enhancement  or  Software  Combined  Release  supplied by the
         Vendor  during the Term of this  Contract has the effect of  preventing
         the System and/or any PCS System and/or any PCS Sub-System, as the case
         may  be,  or  any  part  thereof  from  satisfying,  or  performing  in
         accordance with the Specifications, the System Standards and/or Exhibit
         F or otherwise  adversely  affects the functionality or features of the
         System,  any PCS System,  any PCS Sub-System or any part thereof,  then
         the Vendor will promptly  retrofit or take such other corrective action
         (including  the  Installation  of  any  additional  Equipment,  at  the
         Vendor's  sole cost and expense) as may be necessary to assure that the
         System,  any such PCS  System,  any  such  PCS  Sub-System  or any such
         affected  part  thereof,  as  modified  to include  each such  Software
         Upgrade,  Software  Enhancement  or  Software  Combined  Release,  will

         and  features,  in each case  without  any cost or expense to the Owner
         (other than payment of the applicable  Annual Release  Maintenance Fees
         pursuant  to the  terms  of this  Contract).  Notwithstanding  anything
         contained in this  subsection  12.4 to the contrary,  the Owner will be
         responsible  for  the  cost of any  additional  Equipment  required  to
         accommodate  additional  capacity,  memory or  processing  requirements
         necessitated by any new Software feature contained in any such Software
         Enhancement or Software Combined Release."

         10.   Amendments to Section 13.

               Subsection 13.3 is hereby amended by making it subsection 13.3(a)
and adding the following subsection 13.3(b) thereafter:

                  "(b) Notwithstanding  anything contained in subsection 13.3(a)
         above,  the testing of the  Equipment  associated  with the  Additional
         Products by the Vendor and the acceptance  thereof by the Owner must be
         performed in  accordance  with  Exhibit B4,  Exhibit D and the relevant
         Specifications."

         11.   Amendments to Section 15.

          Section 15 is hereby amended by adding the following  subsection 15.11
         immediately after subsection 15.10:

          "15.11  Additional  Products  and Services  Delay.  (a) Failure of the
          Vendor to deliver the Additional  Products subject to a Purchase Order
          on or before the date scheduled therefor pursuant to the terms of this
          Contract and/or the relevant  Purchase Order will result in the Vendor
          owing  the Owner an amount  in  purchase  credits  equal to [ ] of the
          value of the delayed  portion of any such  Purchase  Order  divided by
          thirty (30) days per day commencing on the date  originally  scheduled
          for such delivery and  continuing for a period of thirty (30) days for
          a maximum  amount of [ ] of the  value of such  late  Purchase  Order.
          Notwithstanding  anything herein to the contrary, on the thirtieth day
          after the original  date  scheduled  for the delivery of any such late
          portion of any such Purchase Order, the Owner will be entitled, in its
          sole and absolute  discretion,  to cancel any such late portion of any
          Purchase  Order  without  payment or penalty of any kind. If the Owner
          chooses not to so cancel such late portion of such Purchase Order, the
          Vendor  will,  at  its  sole  cost  and  expense,  ship  the  affected
          Additional  Products to the Owner's designated location by same day or
          overnight   shipping  or  by  any  other  expedited  means  reasonably
          acceptable to the Owner.

                  (b) Failure of the Vendor to properly  and  timely  Commission
          the Additional Products subject to a Purchase Order  pursuant  to the
          requirements  of Exhibit B4 will result in the Vendor being  obligated
          to pay in purchase  credits to the Owner an amount equal to [ ] of the
          value of the late  Commissioning  divided by thirty  (30) days per day
          for a period  not in  excess of thirty  (30) days for  failure  of the
          Vendor to complete such Commissioning on the date originally scheduled
          therefor.  Notwithstanding  the above,  in no event will the Vendor be
          obligated to incur late fees under this subsection  15.11(b)) for late
          Commissioning  with respect to Purchase Orders that have been deferred
          by the Owner pursuant to the terms of subsection 7.9.

                  (c) Failure of the Vendor to properly and timely Optimize  the
          Additional  Products  subject  to a  Purchase  Order  pursuant  to the
          requirements  of Exhibit B5 will result in the Vendor being  obligated
          to pay in purchase  credits to the Owner an amount equal to [ ] of the
          value of the late Optimization divided by thirty (30)

<PAGE>


                  days per day for a period  not in excess  of thirty  (30) days
         for failure of the Vendor to  complete  such  Optimization  on the date
         originally  scheduled therefor.  Notwithstanding the above, in no event
         will the Vendor be  obligated  to pay late fees  under this  subsection
         15.11(c) with respect to Purchase Orders that have been deferred by the
         Owner pursuant to the terms of subsection 7.9.

                  (d) Except as  otherwise  provided in this  subsection  15.11,
         late fees payable under or pursuant to subsection 15.11 will be accrued
         during the applicable cure periods, if any, and offset against payments
         otherwise due to the Vendor. The Vendor will not be liable for any late
         fees pursuant to this Section 15 for a Vendor delay caused directly and
         solely by (i) a Force Majeure event  pursuant to Section 16 or (ii) the
         direct  and  explicit  act  or  omission  of  the  Owner,  its  agents,
         subcontractors or any other vendor."

         12.   Amendments to Section 17.

               (a)  Subsections  17.1(a) and (b) are hereby  amended by deleting
them in their entirety and replacing them with the following subsection 17.1:

         Products to the applicable FOB Point or the Designated  Switch Site, as
         the case may be (the "Product Warranty  Period"),  all Products and the
         Installation  and  Integration  thereof  within  such PCS System or PCS
         Sub-System,  as the  case  may be,  will  materially  conform  with and
         perform the functions set forth in the relevant  Specifications and the
         relevant performance criteria set forth in Exhibits C, C1 and D, to the
         extent  applicable,  and will be free from Defects and  Deficiencies in
         material or  workmanship  which impair service to  subscribers,  system
         performance, billing, administration and/or maintenance. In the case of
         Software,  the Product Warranty Period  applicable to any such Software
         will be automatically extended for an additional one (1) year upon, and
         simultaneous  with,  any  Software  Upgrade  pursuant  to the  terms of
         Section  12.  The  Vendor  will  assign to the  Owner  all  outstanding
         Subcontractor  warranties  attributable to  Non-Essential  Equipment at
         such time that the Vendor's  warranty on such  Non-Essential  Equipment
         pursuant to this subsection 17.1 expires  pursuant to and in accordance
         with  the  Product   Warranty   Period   applicable  to  such  Item  of
         Non-Essential  Equipment. The Warranty Period for a PCS Product or part
         thereof  repaired  or  provided  as a  replacement  under this  Product
         warranty  is six (6) months or the  unexpired  term of the new  Product
         Warranty  Period  applicable to the repaired or replaced PCS Product or
         part, whichever is longer."

               (b)  Subsection  17.2 is hereby  amended  by  deleting  it in its
entirety and replacing it with the following subsection 17.2:

         the case may be,  provided that the  projections of subscriber  growth,
         traffic and other predictive data,  including all applicable  standards
         as  identified in Exhibits B1, D and H, upon which the Final Site Count
         and Final RF  Design  have been  determined,  have not been  materially
         exceeded or the  applicable  and relevant  industry  standards have not
         materially  changed;  and provided further that in no event will the RF
         Engineering  warranty  pursuant  to this  subsection  17.2(a)  cover or
         warrant items or performance otherwise covered or warranted pursuant to
         subsection 17.3 below.

                  (b) The  Vendor  warrants  that,  for a  period  which  is the
         greater of (i) two (2) years from and after  September 1, 1998 and (ii)
         two (2) years from and after the Specification  compliant completion of
         any such Facilities  Preparation Services (the "Facilities  Preparation
         Services  Warranty  Period"  and  collectively  with  the  RF  Services
         Warranty Period and all other Service warranty  periods,  the "Services
         Warranty Periods"),  such Facilities  Preparation  Services will be (A)
         operational  in  accordance  with the relevant  Specifications,  (B) in
         compliance with all material  Applicable  Laws and material  Applicable
         Permits  in effect  at the time of the  completion  of such  Facilities
         Preparation Services in such PCS System or PCS Sub-System,  as the case
         may be, and (C) free from Defects or Deficiencies.

                  (c) Notwithstanding anything contained herein to the contrary,
         the Vendor  warrants that, for a period which is the greater of (i) two
         (2) years from and after  September 1, 1998 and (ii) two (2) years from
         and after the  completion of each other Service  provided by the Vendor
         hereunder,  such Service will be (A) operational in accordance with the
         relevant Specifications, (B) in compliance with all material Applicable
         Laws and  material  Applicable  Permits  in  effect  at the time of the
         completion  of such  Additional  Service  in  such  PCS  System  or PCS
         Sub-System,  as  the  case  may  be,  and  (C)  free  from  Defects  or
         Deficiencies."

               (c)  Subsection  17.3 is hereby  amended  by  deleting  it in its
entirety and replacing it with the following subsection 17.3:

                  "17.3 System Warranty.  The Vendor warrants that, for a period
         ending three (3) years from the Final Acceptance of the last PCS System
         within the Initial System (the "System Warranty  Period"),  the ongoing
         performance  of each PCS System and PCS  Sub-System  together  with all
         other PCS Systems and PCS  Sub-Systems  within the System will  conform
         with and perform to the performance  criteria set forth in Exhibit F as
         of the date of the Final  Acceptance  of such PCS  System  based on the
         circumstances within such PCS System on such date;  provided,  however,
         that  any  apparent  breach  of the  Vendor's  obligations  under  this
         subsection 17.3 which the Vendor demonstrates conclusively is due

<PAGE>


                  to  the  Installation,   Integration,   Commissioning   and/or
         Optimization of Additional Products by someone other than the Vendor or
         any  Subcontractors  shall be deemed not to be a breach of the Vendor's
         obligations hereunder.  The System warranty pursuant to this subsection
         17.3 will be limited to the extent that the  projections  of subscriber
         growth,  traffic and other  predictive  data,  including all applicable
         standards as  identified  in Exhibits B1, D and H, upon which the Final
         Site  Count  and Final RF Design  have been  determined,  have not been
         materially  exceeded or the applicable and relevant industry  standards
         have not materially changed."

               (d)  Subsection  17.5 is hereby  amended by  changing  subsection
17.5(c)  to  subsection   17.5(c)(i)   and  adding  the   following   subsection
17.5(c)(ii):

                  "(ii) In the event of a breach of the warranties in Section 17
         respecting   Additional,   Products   which  will  be  cured  with  the
         installation of other or further Additional  Products,  the Vendor will
         provide such Additional Products, together with related transportation,
         Installation,  Integration, Commissioning and Optimization Services, as
         are reasonably required to remedy the shortfall,  at no cost or expense
         to the Owner."

               (e)   Subsection   17.7.4  is  amended  by   deleting   the  word
"Interoperability"  in the third line of such  subsection  and replacing it with
the word "interoperability."

               (f)  Section  17  is  hereby  amended  by  adding  the  following
subsection 17.11  immediately after the current  subsection 17.12,  re-numbering
the existing subsection 17.11 as subsection "17.12":

                  "17.11 Year 2000 Compliance  Warranty.  (a) Until the later of
         December  31,  2002 or  three  (3)  years  after  the  delivery  of any
         applicable  Product,  the  Vendor  represents  and  warrants  that  any
         Products  delivered by the Vendor to the Owner under this  Contract are
         designed to be used prior to, during,  and after the calendar year 2000
         A.D.,  and that such Products will operate during each such time period
         without any material performance  affecting error relating to date data
         and   date-dependent   data,   specifically   including   any  material
         performance  affecting  error relating to, or the product of, date data
         which  represents  or references  different  centuries or more than one
         century. Notwithstanding anything contained herein to the contrary, the
         extension of the applicable  Software  warranties pursuant to the terms
         of  subsection   17.1  will  also  extend  the  term  of  the  Vendor's
         obligations  under  this  subsection  17.11  with  respect  to any such
         Software,  as to which any such subsection 17.1 Software warranty is so
         extended.

                  (b) Without  limiting  the  generality  of the  foregoing  the
         Vendor further represents and warrants:

                        (i) That each Product will not abnormally end or provide
        invalid or incorrect results which have a material performance-affecting
        impact as a result of date data,specifically including date data which

<PAGE>


         represents or references different centuries or more than one century;

                        (ii) That each Product has been  designed to ensure date
         data century  recognition,  calculations which accommodate same century
         and  multi-century  formulas and date values,  and date data  interface
         values that reflect the century; and

                        (iii)   That   each   Product    includes   "Year   2000
         Capabilities."   For  the  purposes  of  this   Contract,   "Year  2000
         Capabilities" means each Product manages and manipulates data involving
         dates,  including single century formulas and  multi-century  formulas,
         and will not cause an abnormally ending scenario within the application
         or generate material performance-affecting  incorrect values or invalid
         results involving such dates.

                  (c) At the Owner's  request and upon  reasonable  notice,  the
         Vendor  will  provide  written   evidence   reasonably   sufficient  to
         demonstrate adequate testing and conversion of each Product to meet the
         foregoing requirements."

         13.   Amendments to Section 22.

               (a)  Subsection  22.1 is hereby  amended  by  deleting  it in its
entirety and replacing it with the following subsection 22.1:

                  "22.1 Title.  Free and clear title to each Product (other than
         licensed Software hereunder,  which will be deemed licensed pursuant to
         the terms of this Contract upon  delivery)  will pass to the Owner upon
         delivery  thereof by the Vendor to the System Element Location to which
         each such Item belongs or, with respect to Additional Products,  to the
         designated  FOB Point to which the  delivery of each such Item has been
         designated,  as the case may be; provided that with respect to MSCs and
         associated Equipment and Software free and clear title to each such MSC
         and Item of  associated  Equipment and Software will only pass from the
         Vendor to the Owner upon delivery to the applicable  Designated  Switch
         Site.  Prior to  acquiring  title to the  Products,  the Owner will not
         cause or permit any such Products to be sold,  leased or subjected to a
         lien or other encumbrance."

               (b)  Subsection  22.2 is hereby  amended  by  deleting  it in its
entirety and replacing it with the following subsection 22.2:

                  "22.2  Risk of  Loss.  Risk of  loss of any  Initial  Products
         furnished to the Owner in connection  with this Contract will pass from
         the Vendor to the Owner upon the completion of the  installation by the
         Vendor of any PCS Product or at the completion of  installation  of any
         other Product each at the  appropriate  System Element  Location within
         the given PCS System and/or PCS Sub-System; provided, however, that the
         Owner will  assume the risk of loss prior to such  installation  by the
         Vendor  for  any  such  Initial  Products  damaged  due  to  the  gross
         negligence  or willful  misconduct  of the  Owner.  Risk of loss of any
         Additional Products furnished to the Owner in connection with this

<PAGE>


                  Contract  will  pass from the  Vendor  to the  Owner  upon the
         delivery to the designated FOB Point or Designated  Switch Site, as the
         case may be.  Until such time as risk  passes to the Owner,  the Vendor
         will,  at its sole cost and  expense,  remedy,  repair and  replace all
         physical damage, loss or injury to such property."

         14.   Amendments to Section 26.

               Subsection  26.1 is hereby amended by deleting it in its entirety
and replacing it with the following  subsection 26.1 (provided that with respect
to any MFC Certificates provided or to be provided to the Owner on or before the
effective date of this  Amendment,  any such MFC  Certificates  and the Vendor's
obligations in respect  thereof will be governed by the terms of such subsection
26.1 as they existed immediately prior to the effective date of this Amendment):

                  "26.1 Most Favored Customer.  (a) The Owner will be deemed one
         of the Vendor's most  important  and favored  Customers and will always
         receive   priority  in  terms  of  availability  and  quantity  of  MFC
         Deliverables  no less  favorable  than any other Customer of the Vendor
         and in any event always in accordance  with the terms of this Contract.
         Subject to subsections  26(b) and (c) below, the Vendor guarantees that
         at any time  during  the Term,  the Owner will  receive  Net Prices (as
         determined  pursuant  to  Schedules  2,  2A, 3 and 3A and  taking  into
         account any price  incentives,  discounts and any purchase credits over
         the Term of the  Contract)  for MFC  Deliverables  that are equal to or
         better than those charged to any other of the Vendor's Customers (other
         than Affiliates) for the use of same or similar deliverables within the
         United States who are involved in transactions  and/or  arrangements of
         similar or lesser volumes (for the purposes hereof,  the Owner's volume
         will  always  be  deemed  to be at  least  the  level  of  the  Initial
         Commitment  plus the Additional  Product  Commitment  hereunder and any
         more PCS Products,  Services  and/or  Engineering  ordered at such time
         during  the  Term of this  Contract).  Equipment  Enhancements  must be
         provided to the Owner by the Vendor, if requested by the Owner, and the
         Owner is  obligated  to make  payment  therefor in an amount that is no
         higher than that  payable by any Customer  other than the Owner,  which
         amount of payment will be adjusted as set forth in subsections 7.2, 8.4
         and this Section 26.1.

                  (b) The Vendor will not be deemed to be in  violation  of this
         Section 26 in the event that the Vendor  grants a price  concession  to
         any Customer for a specific MFC Deliverable  specifically in connection
         with the resolution of a specific  contractual dispute or threatened or
         actual  litigation  with such Customer which results in a Net Price for
         that MFC  Deliverable  lower than the Net Price  provided to the Owner.
         The Vendor will also not be deemed to be in  violation  of this Section
         26 in connection with (i) Vendor sales of MFC  Deliverables to a United
         States  government  entity  purchasing MFC  Deliverables for government
         use, (ii) Vendor sales of used and/or refurbished MFC Deliverables,  or
         (iii) Vendor sales of MFC Deliverables  that are subject to a notice of
         discontinued  availability,  provided  that the  Owner  has been  given
         written notice and the opportunity to

<PAGE>


                  purchase a  reasonable  allocation  of such  discontinued  MFC
         Deliverables  at a Net Price less than or equal to such  Customer's Net
         Price for such MFC Deliverables.

                  (c) For the purposes of  determining  the Vendor's  prices for
         MSC(s) sold to Customer(s) the pricing of BTSs and/or Growth  Cabinets,
         if any,  sold to such  Customer(s)  under the same  contract  with such
         MSC(s) may be  referenced  in  determining  the actual  pricing of such
         MSC(s).  The following  example shall  instruct the  application of the
         immediately  preceding  sentence:  If the Vendor is selling BTSs to the
         Owner at $100 per BTS and MSCs at $450 per MSC and the Vendor  proceeds
         to sell to a Customer 5 BTSs at $150 per BTS and 1 MSC at $300, then in
         determining  whether the Vendor has  violated  the terms of  subsection
         26.1(a), the $50 per BTS charged to the Customer in excess of the price
         charged to the Owner may be added to the price to the  Customer  of the
         MSC (i.e.,  $300 plus (5 x $50) = $550).  In such case the price deemed
         to have been actually  paid by the Customer  under this example is $100
         in excess of the Owner's MSC price and, therefore,  not in violation of
         the terms of subsection 26.1(a).

                  With  respect to BTS and Growth  Cabinets  sold under the same
         contract  to  any  other  Customer,  the  Vendor,  in  connection  with
         determining its compliance with subsection  26.1(a),  may reference the
         pricing of Growth  Cabinets  with respect to BTSs and BTSs with respect
         to Growth Cabinets  whenever the pricing of one such Product is used by
         the Vendor to  subsidize  and/or  reduce the  pricing of the other such
         Product.  The following  example shall instruct the  application of the
         immediately  preceding  sentence:  If the Vendor is selling BTSs to the
         Owner at $100 per BTS and Growth Cabinets at $50 per Growth Cabinet and
         the Vendor  proceeds to sell to a Customer 10 BTSs at $75 per BTS and 5
         Growth  Cabinets  at $100 per  Growth  Cabinet,  then,  in  determining
         whether the Vendor has violated the terms of  subsection  26.1(a),  the
         $50 per Growth  Cabinet  charged to the Customer in excess of the price
         charged to the Owner may be added to the price to the  Customer  of the
         BTSs  (i.e.,  ($75 x 10) plus ($100 x 5) = $1,250).  In such case,  the
         price  deemed to have been  actually  paid by the  Customer  under this
         example is equal to the Owner's BTS and Growth Cabinet combined pricing
         for the same quantity of BTSs and Growth Cabinets and,  therefore,  not
         in violation of the terms of subsection 26.1(a).

                  With  respect to BTSs and  Optional  Additional  Services  (or
         services  similar  thereto)  sold under the same  contract to any other
         Customer,  the Vendor,  in connection  with  determining its compliance
         with  subsection  26.1(a),  may  reference the pricing of such services
         with respect to BTSs  whenever the pricing of any such services is used
         by the Vendor to subsidize  and/or reduce the pricing of such BTSs. The
         following  example shall instruct the  application  of the  immediately
         preceding sentence:  If the Vendor is selling BTSs to the Owner at $100
         per BTS and Optional  Additional Services for such BTSs at $10 for such
         similar  services (on a per BTS basis) and the Vendor  proceeds to sell
         to a Customer 10 BTSs at $90 per BTS and  services for such BTSs at $20
         per each such BTS, then, in determining whether the Vendor has violated
         the terms of subsection  26.1(a),  the $10 per BTS services  charged to
         the Customer in excess of the price charged

<PAGE>


                  to the Owner may be added to the price to the  Customer of the
         BTSs  (i.e.,  ($90 x 10) plus ($20 x 10) = $1,100).  In such case,  the
         price  deemed to have been  actually  paid by the  Customer  under this
         example is equal to the Owner's BTS and  Optional  Additional  Services
         combined  pricing  for the  same  amount  of  BTSs  and  services  and,
         therefore, not in violation of the terms of subsection 26.1(a).

                  In  determining  whether the Vendor is in compliance  with the
         terms  of  this  Section  26  in  connection   with  the  sale  of  MFC
         Deliverables   to   Customers   which  have  granted  the  Vendor  firm
         contractual  commitments  as to the then  present and future  exclusive
         purchase  and use of the  Vendor's  PCS  CDMA  products  in all of such
         Customer's  PCS  markets,  the Vendor will be entitled for the purposes
         hereof to deem the Net Prices  charged to such Customer to be up to 10%
         higher than the Net Prices actually charged to such Customer.

                  (d) In the event that a Net Price  charged to any other of the
         Vendor's  Customers  for any MFC  Deliverable(s)  is lower than the Net
         Price previously charged to the Owner for such MFC Deliverable(s),  the
         Owner is  entitled  to receive the benefit of such lower Net Price with
         respect to any MFC  Deliverable(s)  invoiced to but not yet paid for by
         the  Owner  from and  after  the time  such  lower  Net Price was first
         provided  to such other  Customer.  In  addition,  such lower Net Price
         shall be applied to all subsequent purchases of such MFC Deliverable(s)
         by the  Owner  during  the  remainder  of the Term  (subject  to future
         reductions pursuant to this Section 26).

                  (e) All invoices for MFC  Deliverable(s)  to which a lower Net
         Price is applied  pursuant  to this  Section 26 will be reissued by the
         Vendor within thirty (30) days after notification is sent to the Owner.
         The reissued invoice must indicate the difference between the Net Price
         originally  invoiced to the Owner and the  reduced Net Price,  together
         with all applicable  sales or other tax reductions  attributable to the
         price  reduction.  The reduction in Net Price made in  accordance  with
         this Section 26 shall be reflected on all future invoices issued by the
         Vendor to the Owner  (subject  to future  reductions  pursuant  to this
         Section 26). If the Owner has paid  invoice(s)  that would otherwise be
         required to be reissued  hereunder,  then at the  Owner's  option,  the
         Vendor  will  credit the Owner's  account  with the  Vendor,  or make a
         payment  to the  Owner,  in  either  case  in an  amount  equal  to the
         aggregate  amount of the  difference  between the Net Price paid by the
         Owner for each affected MFC  Deliverable and the reduced Net Price paid
         or charged to such other Customer for each such MFC Deliverable.

                  (f) On an annual basis  throughout  the Term of this  Contract
         commencing  on January 1, 1998 the Vendor will be required to audit its
         offering of all MFC Deliverables provided to the then-existing ten (10)
         largest of its  Customers  (other than  Affiliates  and based on volume
         purchased  or to be  purchased)  in the  preceding  calendar  year  and
         deliver to the Owner a certification (the "MFC Certificate")  signed by
         an authorized officer or the Vendor certifying that this Section 26 has
         been adhered to and identifying  what, if any, Net Price(s)  charged to
         the Owner have been or should be decreased as a result of

<PAGE>


                   compliance with this Section 26. The MFC Certificate  will be
         provided  to the Owner  within  sixty (60) days after the close of each
         calendar  year.  If after  discussion  with the Vendor  concerning  the
         accuracy of the MFC Certificate the Owner reasonably believes that such
         MFC  Certificate  may in fact  not be  accurate,  the  Owner  shall  be
         entitled to have the Vendor's  compliance with this Section 26 verified
         by an Independent  Auditor  chosen by the Owner.  The costs of any such
         Independent  Auditor  will be borne by the Party whose  position,  upon
         final  determination  pursuant to the terms of this subsection 26.1(f),
         is not supported by such Independent  Auditor.  The Independent Auditor
         will be required to complete  its report  pursuant to the terms  hereof
         within  sixty  (60) days from the date of notice  from the Owner to the
         Independent   Auditor.  The  Owner  understands  and  agrees  that  the
         Independent  Auditor  will,  at the  Vendor's  request,  be  subject to
         reasonable  confidentiality  restrictions  with respect to the Vendor's
         product and service  pricing  information  and will only have access to
         such Vendor  product and service  pricing  information as is reasonably

          - Cluster Optimization Acceptance Form (APPENDIX A). The form includes
            all exit  statistics plus a list of problems identified which are
            over  and  above  meeting  the exit criteria.

Optimization Team

          - Pricing  assumes an  Optimization Team consisting of the following:
            Driver(s), RF engineer(s) Data Collector(s), and Data  Processor(s)
            as  required. The number of each resource deployed depends upon the
            number of available clusters and size of the system being optimized.

Assumptions

     Vendor cell site and switch equipment only,

     Data Processor, Data Collector, and driver are local to the market

     Price/cell assumes  acceptable  response time from Owner on activities that
     Vendor is not responsible for.

     Vendor will provide their own data analysis  tools,  which does not include
     PlaNET.

     Antenna  adjustments  are the  responsibility  of  Owner.  Pricing  assumes
     acceptable response for antenna adjustments.

     Cost of ANY  delay  (even 1 week or  less)  due to  Owner  unable  to begin
     optimization  will be a cost to Owner,  regardless if Owner chooses to send
     Vendor home or pays Vendor to stay on-site.

     Workweek is defined as 40 hours (5 days per week x 8 hours per day)

     Once Vendor  resources  are placed in a market it is assumed that all cells
     sites which need to be  optimized  are  available  in order to sustain that
     team.  If all cell sites are not ready as planned  to sustain  the team,  a
     daily fee of $4,000  will be  charged.  If Vendor  did not  perform  the RF
     design  of any  system,  Vendor  will  not  be  responsible  for  achieving
     performance exit criteria.  Performance exit criteria defined by Owner will
     be goals only for  optimization.  Vendor is only responsible for performing
     due diligence in obtaining these objectives.

     Maintenance of cells is the responsibility of Owner.

     Base  stations  that are part of a  cluster  will  not be  optimized  on an
     individual basis. They must be optimized in clusters (number of cells to be
     determined mutually).

     All clusters defined will be mutually agreed upon.

     All drive routes will be jointly  defined by Vendor and Owner in advance of
     work beginning in a market.

     Agreement will be reached on coverage areas.

     Agreement will be reached on defining "no coverage".

<PAGE>

     Any area that can not clearly be  optimized  due to the  following  reasons
     will be classified as a "Performance  Exclusion  Zone".  Data gathered from
     that zone will be removed from the exit criteria sample set:

          Lack of RF coverage

          Prohibitive interference beyond the control of the engineers

          Non-standard hardware configurations using another vendor's equipment.

     All cells in a given cluster have completed  integration  and are ready for
     optimization.  Cell site  integration  includes power  calibration and call
     through  testing  inside and outside the base station.  Cell site readiness
     for optimization also includes:

          Manual diagnostics - ATP

          Routine Diagnostics - ATP

          Functional test - ATP

          All integration records must be available to the optimization team.

     If cell  installation  and integration was not performed by Vendor and does
     not meet Vendor  Optimization  Service  entrance  criteria,  a daily fee of
     $4,000 will be charged  for Vendor  personnel  to correct  the  problems to
     prepare for optimization.

     An Optimization Plan and Schedule will be agreed-upon prior to start dates.

     Owner will provide a qualified  cell  technician  to work with Vendor on RF
     Optimization of CDMA Growth Cells.

     Owner staffing as per the  Optimization  Plan will be in place prior to the
     start of Optimization Services.

     Owner will provide  Vendor  personnel  with adequate  workspace,  including
     desks, office equipment (copier & fax machine) and access to telephones.

     Agreement will be reached on how resources will be re-assigned in the event
     conditions in a market  indicate loss of  productivity  for any significant
     period of time.

               CLUSTER AND SYSTEM OPTIMIZATION SERVICE - NEW CELLS

Statement of Work

New Cell Cluster and System Optimization:

Cluster  Optimization  testing for new CDMA markets  will be performed  per
Vendor documented optimization process. The objective of cluster optimization is
to reach system  performance  goals in a manageable  subset of contiguous  cells
within the system. During cluster  optimization,  coverage holes are identified,
neighbor  lists,  access  windows and system  parameters  are  modified  through
analysis of drive test data to improve performance.

System  Optimization is the process where individual  clusters are combined
together  so  that  the  system  as a  whole  provides  the  best  coverage  and
performance  possible.  Vendor  performs  System  Optimization  among  completed
clusters throughout the Optimization period.


Processes for Cell Cluster and System Optimization include:

  - Cluster definitions, drive routes for each defined cluster, and drive routes
    between adjacent clusters (System  Optimization)  will be defined by Vendor
    with agreement by Owner RF teams on a per market basis.

  - Baseline drive test for each drive route (Unloaded).

  - Drive test the selected routes (Unloaded & Loaded).

  - Analyze drive test data.

  - Optimization  changes  made as  necessary  to cell  sites on  drive routes:

  - Parameter changes (e.g. Power attenuation)

  - Neighbor list changes

  - Antenna alignment  recommendation  (if acceptable for analog  system)

  - Origination, termination, and drop call tests performed on defined drive
    routes.

     statistics  plus a list of  problems  identified  which  are over and above
     meeting the exit criteria.


Optimization Team

     Pricing  assumes  an   Optimization   Team  consisting  of  the  following:
     Driver(s),  RF  engineer(s)  Data  Collector(s),  Switch  engineer and Data
     Processor(s) as required. The number of each resource deployed depends upon
     the number of available clusters and size of the system being optimized.

ASSUMPTIONS:

     Vendor cell site and switch equipment only,

     Data Processor, Data Collector, and driver are local to the market

     Price/cell assumes  acceptable  response time from Owner on activities that
     Vendor is not responsible for.

     Vendor will provide their own data analysis  tools,  which does not include
     PlaNET.

     Antenna adjustments are the responsibility of Owner.

     Pricing assumes acceptable response for antenna adjustments.

     Cost of ANY  delay  (even 1 week or  less)  due to  Owner  unable  to begin
     optimization  will be a cost to Owner,  regardless if Owner chooses to send
     Vendor home or pays Vendor to stay on-site.

     Workweek is defined as 40 hours (5 days per week x 8 hours per day)

<PAGE>



     Once Vendor  resources  are placed in a market it is assumed  that all cell
     sites which need to be  optimized  are  available  in order to sustain that
     team.  If all cell sites are not ready as planned  to sustain  the team,  a
     daily fee of $4,000 will be charged.


     If Vendor did not perform  the RF design of any system,  Vendor will not be
     responsible  for achieving  performance  exit  criteria.  Performance  exit
     criteria  defined by Owner will be goals only for  optimization.  Vendor is
     only responsible for performing due diligence in obtaining these objectives


     Maintenance of cells is the responsibility of Owner.

     Base  stations  that are part of a  cluster  will  not be  optimized  on an
     individual basis. They must be optimized in clusters (number of cells to be
     determined mutually).

     All clusters defined will be mutually agreed upon.

     All drive routes will be jointly  defined by Vendor and Owner in advance of
     work beginning in a market.

     Agreement will be reached on coverage areas.

     Agreement will be reached on defining "no coverage".

     Any area that can not clearly be  optimized  due to the  following  reasons
     will be classified as a "Performance  Exclusion  Zone".  Data gathered from
     that zone will be removed from the exit criteria sample set:

          Lack of RF coverage

          Prohibitive interference beyond the control of the engineers

          Non-standard hardware configurations using another vendor's equipment.


     All cells in a given cluster have completed  integration  and are ready for
     optimization.  Cell site  integration  includes power  calibration and call
     through  testing  inside and outside the base station.  Cell site readiness
     for optimization also includes:

          Manual diagnostics - ATP

          Routine Diagnostics - ATP

          Functional test - ATP

          All integration records must be available to the optimization team.

     If cell  installation  and integration was not performed by Vendor and does
     not meet Lucent's  Optimization  Service entrance criteria,  a daily fee of
     $4,000 will be charged  for Vendor  personnel  to correct  the  problems to
     prepare for optimization.

     An Optimization Plan and Schedule will be agreed-upon prior to start dates.

     Owner will provide a qualified  cell  technician  to work with Vendor on RF
     Optimization of CDMA Cells.

     Owner staffing as per the  Optimization  Plan will be in place prior to the
     start of Optimization Services.

     Owner will provide  Vendor  personnel  with adequate  workspace,  including
     desks, office equipment (copier & fax machine) and access to telephones.

     Agreement will be reached on how resources will be re-assigned in the event
     conditions in a market  indicate loss of  productivity  for any significant
     period of time.

                            BASE STATION REQUIREMENTS




DEFINITIONS:

Carrier:  A 1.25  MHz  radio  channel  that is used in  pairs,  one for the
downlink (BTS to mobile) and a second on the uplink (mobile to BTS).

Effective Voice Channel: An effective voice channel is a channel element in
a sector that  supports  voice  traffic.  This is exclusive of channel  elements
required for paging,  synchronization,  pilot,  soft hand-off,  softer hand-off,
soft-softer  hand-off or other  maintenance  activities.  As such, the effective
voice channel is used to calculate the traffic capacity, measured in Erlangs, of
a sector.

Hard  hand-off:  Hand off from carrier to carrier;  either within a sector,
between different sectors, or between different cells.

Inter system hand-off:  A hand-off between two MSCs or BSCs. The MSCs and / or
BSCs may be from different vendors.

Macro BTS (Minicell): A full range cell. A micro cell is smaller than macro
cell and is designed for "hot spots".

Operations and  Maintenance  Platform  (OMP):  An element level  management
system that controls and monitors the switching and radio subsystems.  The radio
and switching OMPs may be different.

Outdoor BTS: A self contained unit that is environmentally hardened, and has
self contained battery backup. Any type of BTS can be an outdoor BTS.

Pico BTS: Low power, low capacity cell primary for deployment in building. Can
also be used outdoor.

PCS bands: The FCC designated bands for PCS operation are as follows:
- - ------------------------ ---------------------------- ------------------------

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

Physical Traffic Channels:  Channel elements that are used to perform processing
in a  sector.  These  channels  can be used for  pilot,  paging,  voice  and all
versions of soft hand-off. Soft hand-off: Hand-off that involves 2 or 3 cells on
the same  carrier.  A soft  hand-off  will result in no more than 2 frames lost.
Softer  hand-off:  Hand-off from sector to sector  within a cell.  This shall be
performed on the same carrier.  A softer  hand-off will result in no more than 2
frames lost. Soft softer hand-off:  Hand-off between 2 sectors of one cell and a
sector of a different cell on the same carrier.

EXHIBIT D.BTS:  BTS REQUIREMENTS:

GENERAL:
Unless  specifically  excepted,  the  following  requirements  apply  to all BTS
products, indoor and outdoor.

D.BTS.1           AIR INTERFACE REQUIREMENTS:

D.BTS.1.1         COMPLIANCE TO STANDARDS:
All BTS equipment must comply with  ANSI-J-STD-008  and shall support rate set 2
and  multiplex   option  2  as  described  in   ANSI-J-008.   This  will  ensure
compatibility with 14.4 kbps and 9.6 kbps data rates.

D.BTS.1.2         HAND-OFF CAPABILITY:
The BTS shall have the capability to support the following types of hand-offs:
Soft hand-off:  Hand-off that involves 2 or 3 cells on the same carrier.  A soft
hand-off will result in no more than 2 frames lost. Softer: Hand off from sector
to sector within a cell.  This shall be performed on the same carrier.  A softer
hand-off  will  result  in no more than 2 frames  lost.  Soft  softer:  Hand-off
between 2 sectors of one cell and a sector of a different  cell.  A  Soft-softer
hand-off will result in no more than 2 frames lost. Hard hand-off: Hand-off from
carrier  to  carrier  either  within  a  sector  or  between   different  cells.
Acquisition  time is less than 200ms and number of lost  frames is less than 15.
Interfrequency  hand-off:  A  hand-off  between a 1.9 Ghz and a 850 Mhz  system.
Acquisition time is less than 200ms.

In all cases the hand-off process must perform as described in ANSI-J-STD-008.

D.BTS.1.3         INTER BAND  HARD HAND-OFF:
The BTS shall be able to  support  band to band hard  hand-off.  Such a hand-off
must  support  a  hand-off  between  any  combination  of  bands  A-F of the FCC
allocated  PCS spectrum.  When such  hand-offs  are  inter-vendor  they shall be
supported to the extent that appropriate standards exist.

D.BTS.2           REQUIREMENTS FOR MULTI CARRIER OPERATION:

D.BTS.2.1         HARDWARE:
D.BTS.2.1.1       Growth pattern to accommodate multiple carriers:
The Owner  requires  that the PCS CDMA macro  cellular  product (both indoor and
outdoor)  grow to  accommodate  at least 6 CDMA 1.25  carriers for each 3 sector
site.  The  growth  from one  carrier to 6 carriers  can be  achieved  by adding
additional  bays to an existing  initial bay. The growth  hardware  must include
whatever cabling, combining,  amplification,  and duplexing is needed to provide
for additional carriers.

D.BTS.2.1.2       Antenna requirements:
The Owner will be deploying its PCS products with as few antennas as possible.

The CDMA BTS can  support  up to two (2) CDMA  carriers  per  sector  on two (2)
antennas per sector.  This requires the inclusion of additional  Duplexers (Full
Duplex Option).  In this  configuration,  both antennas  operate as transmit and
receive. The standard configuration includes two (2) duplex filters.
This allows both (1) antennae to operate as transmit and receive.


<PAGE>


D.BTS.2.2         TRAFFIC MANAGEMENT:
In a multi carrier  operation,  the radio subsystems must be able to manage
traffic across any carrier that may be present in a particular  sector.  Traffic
management is defined as the ability to balance traffic as follows:

1)    Originate and terminate calls on or to any carrier present in a sector.

2)    The ability to dynamically move a call in process from one carrier to
      another carrier that is on a separate frequency.

D.BTS.2.2.1       Load balancing during origination and termination:
The system  shall  implement a function  which will  allocate  originations  and
terminations across the available CDMA carriers.  Allocation is to be based upon
the available capacity in each sector.

D.BTS.2.2.2       Load balancing for a call in process:
For the purpose of  executing  hand-offs,  the system  shall have the ability to
move users between carriers during an active call on a dynamic basis.  This will
be done when the traffic on any particular  channel exceeds the designed loading
objectives  and a user  or  users  must  be  moved  to  another,  less  utilized
frequency.

D.BTS.2.2.3       Traffic capacity:
The traffic capacity of a sector,  measured in Erlangs,  is based upon the total
traffic  channels  available in a sector.  The total  channels are calculated as
follows:

      N = number of  effective  traffic  channels  available  on a carrier  at a
     particular loading  (percentage of pole). This number excludes the channels
     required for overhead channels and hand-offs.
      C = number of carriers in a sector Total Channels = N x C

The total channels are to be used in the  appropriate  Erlang table to determine
the capacity of a sector.  This capacity  criterion shall apply to both calls in
progress or call origination or termination.

D.BTS.2.3         POOLING PHYSICAL ELEMENTS WITHIN A CARRIER:
The BTS shall be able to pool physical traffic channels across all sectors using
the same carrier  frequency.  As such, a voice  channel on a particular  carrier
frequency  in any sector of a BTS can  utilize  any  physical  traffic  channels
element assigned to the same carrier  frequency.  This capability allows for the
pooling of all the physical channels equipped within one BTS cabinet.

D.BTS.2.4         CHANNEL CARD CAPACITY:
The Vendor shall supply  channel  cards that are capable of  supporting at least
ten (10) physical traffic channels per card.

D.BTS.3  CONTROL REQUIREMENTS:
D.BTS.3.1         ABILITY TO RETUNE FREQUENCIES REMOTELY:
The base transceiver  station must have the ability to tune any channel within a
block of the PCS band (1850-1910 Mhz,  1930-1990 Mhz). The re-tuning  capability
must be administered remotely via the OMP.

D.BTS.3.2         ABILITY TO PERFORM T1 OR OTHER TRANSMISSION LOOP BACK
REMOTELY:
         The BTS / MSC must have the  ability to perform T1 loop backs  remotely
from the MSC.  The  Vendor  and the  Owner  shall  mutually  agree to dates  and
requirements  for  transmission  interfaces  to have  loopback  that the BTS may
support.

D.BTS.3.3         TELEMETRY AND ALARMS:
Telemetry and alarming capability are provided with the BTS software. These
capabilities  include the collection of data and alarms related to the following
cell site systems: environmental (high and low

CDMA Radio Test Unit (CRTU)
CDMA Radio Test Unit (CTRU)

Radio Switch Panel (RSP)



The  estimates  for  Mean-Time-Between-Failure  (MTBF)  for the  major  CDMA PCS
components  shown are based on  typical  environmental  conditions  for the CDMA
growth  frame  which  have  been   derated  by  10%  for  the  outdoor   cabinet
configurations.

All of the Radio Control Complex (RCC) components are duplicated for redundancy.
Failure of any of the RCC components will not result in a loss of service.

In the CDMA Radio  Shelf,  loss of CDMA Channel Unit (CCU) will result in a loss
of  capacity,  but the system will be able to provide  service on the  remaining
CCU's.  The system will be able to reconfigure  CCU's  assigned to pilot,  sync,
page,  and access  channels as necessary to maintain  service.  The  Synchronize
Clock and Tone (SCT) is duplicated for redundancy;  failure will not result in a
loss of  service.  The  system  can  reconfigure  in the event of a loss of CDMA
Cluster  Controller  (CCC),  such that failure of a CCC will result in a loss of
capacity but the system will still  provide  service to each sector.  Failure of
the Bus Interface Unit (BIU),  Analog  Conversion Unit (ACU),  Baseband Combiner
Radio (BCR),  or Power  Converter Unit (PCU) will result in a loss of service to
one sector.

Failure of any of the CDMA Transmit Unit Shelf  components with the exception of
the Alarm  Control  Board  (SCB) will result in a loss of service to one sector.
The Alarm Control Board (SCB) is not service affecting.

In the event of a single  failure in the Reference  Frequency and Test Generator
(RFTG), redundancy within the RFTG shall maintain synchronization with all other
CDMA cell sites for 24 hours.  In the event of a double failure within the RFTG,
synchronization shall be maintained for a minimum of 4 hours.

The Shelf  Interface Unit (SIU),  CDMA Radio Test Unit (CRTU),  and Radio Switch
Panel (RSP) are not service affecting.

Reliability information on the Transmit and Receive Filters are not available at
this time and are not included in the system MTFB  discussed  below.  Generally,
for  system  with  receive  diversity,  failures  in the  receive  path  are not
considered service affecting.

Failure of the entire system (loss of all traffic channels) will result from the
failure of the Digital  Facility  Interface (DFI) or Channel Service Unit (CSU).
The Mean-Time-Between-Failures (MTFB) of these two units is 257,000 hours.

<PAGE>



The  loss of one or more  traffic  channels  in a  sector  due to the loss of an
amplifier  or other common  electronics  will result from the failure of the Bus
Interface Unit (BIU),  Analog  Conversion  Unit (ACU),  Baseband  Combiner Radio
(BCR),  or Power Converter Unit (PCU) in the CDMA Radio Shelf; or from a failure
of the Transmit Power Amplifier (TPA),  TPA Power Supply (TPA-PS),  Tx Amplifier
(Tx  AMP),  or  the  Tx  UP  Board  in  the  CDMA   Transmit  Unit  Shelf.   The
Mean-Time-Between-Failure (MTBF) associated with these units is 40,860 hours.

                                  BTS/BSC - MSC
                                    MSC - MSC
                                INTEROPERABILITY

                                  INTRODUCTION

The Owner standard, open BSC to MSC interface (the "Open A Interface",  or OAI),
is based on industry standard IS634.  Interoperability  between MSCs is based on
industry standard IS41. Lucent proprietary MSC to BSC interfaces may be deployed
in circumstances  where the open or standard  interface is not available,  or is
not needed in the  Owner's  reasonable  opinion.  In cases  where a  proprietary
interface  has been  implemented  in a PCS system,  and an OAI is provided as an
additional  option on such  system,  then it is  desirable  that the OAI  option
support the standardized  capabilities  supported by the proprietary  interface.
All  references  to "D.MSC" are  references  to Exhibit D.MSC to the Amended and
Restated  Procurement and Services  Contract  between Sprint Spectrum  Equipment
Company,  L.P.  and  Lucent,  dated as of  October  9,  1996 (as the same may be
amended,  supplemented  or  modified  from time to time,  the "SSLP  Contract").
Capitalized  terms used herein but not  otherwise  defined  herein or in the MOU
shall have the meanings set forth in the SSLP Contract.


                                MSC CAPABILITIES

The  MSC  shall   provide   the   capabilities   of   D.MSC.1   ("Features   and
Functionalities") when the interface to the radio system is via the OAI.

                                  MSC Retrofit

The Open A Interface shall be made available as an additional  option for any of
the Owner's MSCs purchased,  past or future.  Adding this option will consist of
purchasing  additional  hardware and software specific to the A-Interface itself
and, where necessary,  hardware and software to support traffic growth for added
base stations that goes beyond the existing MSC's engineered capacity.

                              Interface Conformance
 The  Open  A  Interface   shall   conform  to  the  Owner's   Inter-Operability
Specification (IOS), as contained in Exhibit G2.

                         Administration and Maintenance

For purposes of this  exhibit,  "Local MSC Open A Interface"  shall refer to MSC
hardware and software components up to the points of demarcation between the MSC
and BSC,  defined  here as the  physical  signaling  links  and  voice  circuits
connecting the BSC to the MSC.


<PAGE>


The  MSC  shall  meet  the   requirements   of  D.MSC.4   ("Administration   and
Maintenance")  for  administration  and  maintenance  of the  Local  MSC  Open A
Interface.  The  administrative  and maintenance  capabilities for the Local MSC
Open A Interface  shall be  functionally  equivalent  to those  provided  for an
existing proprietary interface between the MSC and a radio system.

The MSC shall be capable of establishing a DS-0 channel within a given DS-1 link
to a  subtending  BSC for  transporting  operations  messages  between the radio
system and an Operations and Maintenance  Center (OMC)  responsible for managing
that radio system.

                                   Reliability

The  Local  MSC  Open  A  Interface  will  meet  the  reliability   requirements
established for the radio system to MSC interface in D.MSC.6.1 ("Reliability").

                           NETWORK TRAFFIC MANAGEMENT

The MSC  shall  provide  traffic  management  controls  for the Local MSC Open A
Interface, meeting the requirements of D.MSC.9.1 ("Traffic Management").

                                    CAPACITY

The OAI shall be able to support 24 CDMA PCS calls  simultaneously per DS-1 link
to the MSC, less the number of required  signaling or operations  channels.  For
any given DS-1, the number of signaling and operations channels may be zero. The
MSC shall  support  system  capacities  for the OAI or a mixture  of the OAI and
proprietary  interfaces no less than that stated in D.MSC.6 ("Service  Standards
and Capacity").  The MSC shall be capable of supporting  individual BSCs up to a
maximum  capacity of 50,000  Busy Hour Call  Attempts  (BHCA).  The MSC shall be
capable of supporting up to 15 BSCs with combined capacity up to the MSC maximum
capacities stated in D.MSC.6 ("Service  Standards and Capacity").  The MSC shall
be capable of supporting a sufficient number of DS-1 links per BSC to allow full
utilization of the BSC BHCA capacity at initial deployment,  so long as the BHCA
capacity does not exceed the value stated in G.6.3 hereof.

Lucent Technologies and Sprint PCS's Software Development Understanding


1.     Purpose of Document and Background
The purpose of this  document is to describe the tasks,  procedures,  and timing
necessary to evaluate and respond to requests for new or improved  functionality
in the  Autoplex(R)  product line from Sprint PCS.  Section 2 covers the process
for feature  development where Sprint PCS has the opportunity to input into that
process.  Section 3 covers the RDAF  process  in more  detail and how Sprint PCS
matches  up their  own  document  to the RDAF  process.  Section  4 looks at the
Platinum Ticket concept for faster development of software  features.  Section 5
addresses the Autoplex(R) Mobile Switching Center (MSC) Fast Feature Development
Process. Section 6 provides alternatives for addressing software concerns.

1.1    Custom Development
Sprint PCS may have  requirements  for features that will be  considered  custom
software development.  As stated in more detail in section 11.9 of the Contract,
Sprint PCS will identify to Lucent,  in writing,  a summary of any such proposed
development of custom software.  This summary from Sprint PCS should be directed
to  the  Customer  Team  Director  of  Sales  with a  copy  to the  Applications
Engineering Team. This summary will provide a description of any proposed custom
software  sufficient to enable  Lucent to determine the general  demand for, and
its plans, if any, to develop the same or similar products.  Lucent will respond
to such summary within thirty (30) days after receipt and indicate if it has the
ability to fulfill a subsequent  Request for Proposal  (RFP) from Sprint PCS for
development of custom software.

2.     Lucent Technologies Wireless Product Life Cycle Process - Overview
The  development of software  features,  from concept to  deployment,  follows a
product life cycle process,  also know as the Lucent Gate Process.  See Figure 1
below. This product life cycle process has `checkpoints' in which Sprint PCS has
an opportunity to provide input or feedback into the process. Section 2 provides
an  overview  of the  process as well as point out areas  within the  process in
which Sprint PCS has the opportunity to input.  These inputs,  discussed  below,
are the RDAF process, FDD review, and priority ranking.


<PAGE>



[GRAPHIC OMITTED]
2.1    Sprint PCS Input.
Sprint PCS has three main areas of input into the product life cycle process.
2.1.1  Sprint PCS's First Input.
The first  opportunity  for input into the  process is at Gate I via the Request
Definition Assessment Form (RDAF). The RDAF process is discussed in section 3.

2.1.2  Sprint PCS's Second Input.
The second  opportunity  for input into the process is after Gate II, but before
Gate III.  This is when  Sprint  PCS has the  opportunity  to review  the Lucent
Feature  Definition  Document (FDD) with Lucent's  Application  Engineering Team
supporting  Sprint  PCS.  In  rare  cases  where  an FDD is  not  created,  then
Application  Engineering  will share the feature design  information with Sprint
PCS before Gate III.

2.1.3  Sprint PCS's Priority Input.
To better  address  Sprint PCS's feature needs and to more  importantly  reflect
upon Sprint PCS's major revenue  contribution  to Lucent,  a new  prioritization
process has been  implemented.  Beginning  with CDMA Release 8.0, Cell 13.0, ECP
13.0,  and 5E13,  Lucent is using a weighted  ranking  scale that  provides  the
proper recognition of revenue contribution to the prioritization of features. In
Sprint PCS's case,  this clearly  ranks their  feature  needs ahead of all other
customers.  This ranking  provides  Sprint PCS the  necessary  "clout" that they
deserve.

     2.2  Product Life Cycle Check Points
The  sub-sections  below list the actions  that take place after a Gate has been
passed and action  that needs to happen  before the next Gate.  This  section is
intended  to show the  various  checkpoints  within the  process.  Also refer to
Figure 1 and Figure 2.

2.2.1  Gate I:   Opportunity Statement
            Customer Need (RDAF)
            Proposed Product Functionality
            Potential Market Assessment
2.2.2  Gate II:  Technical, Marketing, & Business Issues
            Preliminary Business Case
            Proposed Support Strategies

            First Office Application (FOA)
2.2.5  Gate V:   Full Product Deployment
            Generally Availability (GA)

2.3    Product Life Cycle Schedule Timeline
Features  that will be  developed  will be  assigned a software  release.  These
software  releases are tracked  through one of three  programs.  Those  software
program names are CDMA, ECP (MSC), and 5ESS.

Figure 2, below,  shows the product life cycle schedule timeline that points out
the  approximate  timing of how long it takes for a  feature,  that is part of a
release,  to be deployed and when certain  checkpoints  need to be met. There is
typically a 22 month development time frame.

3.     Lucent's Request Definition & Assessment Form (RDAF) Process
The RDAF Process is used to review and track requests  originating from internal
Lucent   organizations  and  AUTOPLEX  customers  (Sprint  PCS).  All  requests,
regardless of the  origination,  must be made via the RDAF.  The process  begins
when a Lucent  employee  or a customer  through a Lucent  employee  (Application
Engineering),  requests a new  feature/enhancement  by way of the RDAF form. The
RDAF process  includes the logging of the request,  as well as the  gathering of
the necessary  technical and marketing  information in an organized  fashion for
Product  Management  to evaluate the  request.  The process  concludes  with the
Product  Manager  documenting  disposition of the request via electronic mail to
the Lucent originator and Customer Business  Management (CBM). The CBM will work
up the response to the customer and send that response on to the Customer  Team.
It is the  responsibility  of the Lucent  originator  and the  Customer  Team to
forward  the  Product  Manager's  and  CBM's  response  to the  customer,  where
applicable.


<PAGE>



3.1 Sprint PCS's Input into the RDAF process.
Sprint PCS has a document called Request Feature  Definition  (RFD) that,  after
written by Sprint PCS,  easily converts to a Lucent RDAF. A Sprint PCS requested
RDAF is filled out by the  Applications  Engineering Team responsible for Sprint
PCS. The  Application  Engineering  Team works with Sprint PCS to convert Sprint
PCS's RFD to a RDAF.

Once  the RDAF is  submitted,  Lucent  will  respond  within  60 days or less to
estimate the request. For PMUG related RDAFs Lucent will respond within 30 days.

     4.0  Platinum Ticket
It is critical that Sprint PCS remain the leader in the fiercely competitive PCS
marketplace.  Sprint PCS's business relationship is vitally important to Lucent,
so Lucent wants to provide not only assurance,  but action that if the situation
ever presents itself where a feature is deployed to the marketplace  (GSM, TDMA,
another PCS provider, an 850 provider) that Sprint PCS will be covered by way of
Lucent  reacting  to  support  Sprint PCS and help  Sprint  PCS not lose  market
advantage.  This  process  will  remain  in  effect  until  release  9.0 is made
generally available.

To assure  Sprint PCS of Lucent's  intentions,  Lucent will offer Sprint PCS one
"Platinum  Ticket",  per release,  that is to be used within that  calendar year
beginning  January 1998.  Lucent clearly  understands  the importance of time to
market in feature  deployment  and is committed to be responsive to Sprint PCS's
needs.  Sprint  PCS will have one  `Platinum  Ticket'  per  release  that can be
"cashed" to make certain that no feature is deployed in a Sprint PCS market that
Sprint PCS was, for whatever reason,  unaware of and cannot afford to be late in
deploying a similar feature.

4.1    New Feature Request
A new  feature  request  would be  defined as a feature  whereby  Lucent has not
received  an RDAF.  This Sprint PCS request  will  engage the  pertinent  Lucent
executive   groups  including   Application   Engineering,   Customer   Business
Management, and Product Management, Systems Engineering and Development.  Lucent
will immediately pull together the required  resources (a conference call within
48 hours and a meeting within five (5) working days) to counter-attack a feature
that would be in  competition  with a Sprint PCS market.  This feature must be a
subscriber  calling  feature.  This process would  specifically  exclude network
performance features,  platform affecting features,  and  IS634/Interoperability
features. Specifics, such as feature functionality,  feature estimation, systems
engineering  requirements,  development,  testing,  etc.  would be addressed and
reasonably negotiated by an emergency task force of Lucent management.

A Platinum  Ticket that is cashed to create a Platinum  Feature can only be used
for a feature that lies in the CDMA,  ECP (MSC),  5ESS, or WIN programs.  Once a
Platinum Ticket is cashed, it cannot be reused. It will be mutually communicated
and  understood by all parties what impacts  utilizing  the Platinum  Ticket may
have on other Sprint PCS feature requests, including already committed features.

<PAGE>



4.2      Existing Feature Request
There might also be a situation where Lucent has received a RDAF from Sprint PCS
that has been recently identified as a competitive  feature.  However,  based on
customer priorities,  requirement definitions, terminal issues, etc., Lucent has
targeted this particular  feature for a future  release.  In the event that this
unknown  competitive  feature is targeted for a release before Lucent's  planned
release,  Sprint could utilize their "Platinum Ticket" to request the pull-up of
such a competitive  feature to an earlier  Lucent  release.  Lucent will put its
best effort  forward to pull the  requested  feature up to an agreeable  date of
delivery  in an earlier  release or in a  software  update to a release.  Timing
restrictions  for this request will have to be discussed on a per feature  basis
given the unknown uniqueness of the feature at hand. Specifics,  such as feature
functionality,    feature   estimation,    systems   engineering   requirements,
development,  testing,  etc. would be addressed and reasonably  negotiated by an
emergency task force of Lucent management.

5.0 Autoplex(R) Mobile Switching Center (MSC) Fast Feature Development  Process.
In order to be more  responsive,  Lucent has developed the Fast Feature  Process
(FFP).  This process  addresses  small,  urgent features that require  immediate
attention.  Specifically,  this  reduces the concept to  delivery  interval  for
smaller  features that have limited system  impact.  This process allows the MSC
team to improve response time to feature  requests  received through the Request
Definition and Assessment  Form (RDAF) process,  and items received  through the
PCS Maintenance  User's Group (PMUG). It also provides the opportunity to reduce
rework by including customers in the feature definition and review process.

5.1    Requirements / Restrictions / Conditions
Targeted as urgent  features that are relatively  small,  Lucent intends to turn
around a feature  request from RDAF to deployment in less than 6 months.  Lucent
will guarantee  Sprint PCS two (2) MSC Fast Features per calendar year providing
the conditions below are met.

The  following  must  be met  for a  feature  to  even  be  considered  for  the
Autoplex(R) Mobile Switching Center (MSC) Fast Feature Development Process:
      No  hardware  development  No 3rd  Party  Vendors  No WIN  involvement  No
      terminal impact Requirements must be stable
      No change to standards or government regulations.

6.0      Additional Alternative Suggestions
In addition to  previously  mentioned  methods of  addressing  Sprint's  time to
market  needs,  there exist other  avenues  which Sprint PCS should  always take
advantage of.


<PAGE>



6.1      PCS Maintenance User Group (PMUG)
Lucent  is  extremely  committed  to our  PCS  customers,  which  is why the PCS
Maintenance Group was founded almost a year ago. The purpose of this forum is to
create and maintain an active  partnership  between PCS CDMA Users and Lucent to
provide  prioritized  deliverables  and  direction  for system  maintenance  and
development.

A critical component to the PMUG forum is the Action Item Review meetings.  This
is where status is provided as to the action items customers, especially Sprint,
bring to Lucent's attention.

Sprint PCS also has the  opportunity  to gather  great  market  and  competitive
information  by  attending  these  forums.  PMUG is just one  place  where  many
customers  and/or  groups of  customers  express (or  demand)  new or  expedited
development.  The combined  influence  of many  customers  purchasing  power has
significant impact on Lucent's  development  programs.  Sprint PCS certainly has
the  leverage  to  influence  such a  conference  in the  feature  direction  it
requires.

From a competitive market data perspective, the entire PCS CDMA operator base is
present at this forum  expressing their future feature needs -- this can provide
Sprint PCS with a very  early  view of what  direction  other PCS  carriers  are
moving in.

As a reminder,  the next PMUG Action Item Review  meeting which is scheduled for
Tuesday, April 14th at the following location:
                  Lisle/Naperville Hilton
                  3003 Corporate West Drive
                  Lisle, IL  60532
                  (630) 505-0990
                  800-552-2599

If you have any  questions,  please  contact  Anita Besch on (630)  224-7453 for
further information on registration and hotel information.

6.2      Lucent's  3rd Party Programs
Lucent  strives to partner  with those  corporations  that can also  enhance and
speed to market  features  that  compliment  your  existing  markets  as well as
provides the competitive differentiation necessary to be successful.

6.3      Interoperability Lab
This facility is specifically  designed to address Sprint's needs with our staff
ready to respond to Sprint PCS's requests.

Step 1, Lucent Technologies issues the "Approved Products List Change Form" with
associated  reason for change.  This form is to be signed off by the appropriate
Lucent Technologies representative (J. Sotak or a delegate).

Step 2, Sprint PCS inputs the  updates/changes  into the Approved  Products List
(APL) and the appropriate  Sprint PCS representative (J. Sorrentino or delegate)
signs off and dates and  returns  "Approved  Products  List  Change  Form" and a
printout of the updated APL.  Sprint PCS faxes back the form and APL to J. Sotak
Fax 913-338-8888.

Step 3, The Change Form will have an issue number and date. The Change form will
be attached to the updated APL printout to serve as a permanent  record.  Copies

                                    RECITALS

         1.1. This Agreement  including  Exhibits A, B and C as attached  hereto
and  incorporated  herein by  reference,  sets  forth the terms and  conditions,

incorporated by reference into this Agreement,  except as expressly  modified or
supplemented  herein.  Any such modifications or supplements shall apply to this

therein.  In the event of a conflict  between the terms and  conditions  of this
Agreement and the Contract, the Contract shall prevail.


         1.3. For purposes of the Vendor financing with the Owner's parent,  the
Vendor  expressly  agrees that all payments made or to be made hereunder will be
covered  by such  Vendor  financing  as if such  payments  were  made  under the
Contract.


                                 2. DEFINITIONS


         2.1.  "Licensed  Software" means all optional software features for PCS
Products made generally available to Customers in 1996 on an optional,  separate
fee, basis. A current list of these features is set forth on Exhibit A hereto.


         2.2.  "Initial  Application"  means  the  initial  configuration  to be
deployed in Fresno,  California  consisting  of one (1) switch and the number of
base stations within the Initial  Application which are available for testing of

multi-site  (capability  to have  deployed  Licensed  Software  in any number of
sites) right to use license for the Licensed Software ("License") for use on the
Products  purchased  from the Vendor  provided  in each of the  systems  and the
System as a whole,  subject to  payment of license  fees set forth on Exhibit B.
The  Licensed  Software  will  at all  times  throughout  the  term  perform  in
accordance with the Specifications.


                   4. ORDER AND DELIVERY OF LICENSED SOFTWARE


         4.1.  The  Owner agrees  that  the execution of this Agreement shall be
deemed an order for the Licensed Software for its Initial Application.


         4.2.  The Vendor  agrees  to  deliver and install the Licensed Software
for  the  Owner's Initial Application as soon as possible, but, in any event, no

longer than the thirty (30) day period after commencement of acceptance testing.
The Owner will accept or reject the  Licensed  Software  within such thirty (30)
day period unless the parties mutually agree that the Licensed  Software has met
the acceptance  tests prior  thereto.  If the Owner does not provide a notice of
rejection,  then the Licensed  Software  will be deemed to have been accepted at
the end of the  thirty  (30)  day  acceptance  period;  provided  that  any such
acceptance will in no way limit the Vendor's warranty or other obligations under
this  Agreement  and/or the Contract.  If prior to Owner  acceptance,  the Owner
notifies the Vendor of a Defect in the Licensed  Software,  then the thirty (30)
day  acceptance  period  will be  extended  day-for-day  until  the  Vendor  has
corrected the Defect.


         5.2. Minor Defects and  shortcomings  not affecting the operational use
of the  part of the  Licensed  Software  shall  not  give  rise  to  withholding
acceptance  provided  that the Vendor  undertakes  to remedy  such  defects  and
shortcomings as soon as reasonably possible.


         5.3. The Owner and the Vendor further agree that the Owner's acceptance
of the Licensed  Software for the Owner's  Initial  Application  shall be deemed
acceptance of the Licensed  Software by the Owner for deployment of the Licensed
Software in its Nationwide  Network;  provided that nothing herein will limit or
otherwise modify the Vendor's warranty and other obligations hereunder.


                            6. INTELLECTUAL PROPERTY


         Without limiting the generality of Section 1.2, all of the Software and
Intellectual  Property  provisions  of the Contract  shall apply to the Licensed
Software provided herein.


                                   7. WARRANTY


         Without  limiting  the  generality  of Section 1.2, all of the warranty
provisions of the Contract shall apply to the Licensed Software provided herein.

part of the RF Engineering, the Vendor will establish "search rings" in each of
the PCS Systems that will specify areas in which the Owner may proceed with Site
Acquisition.

          (b)  In accordance with Exhibit B1 the Vendor will be kept reasonably
informed of the progress made on ongoing Site Acquisition within the System
Areas.  As the Site Acquisition progresses, the Vendor agrees to regularly alter
the RF Engineering plan to determine a new search ring or rings to take into
account any changes or modifications requested by the Owner due to the Owner's
inability to acquire sufficient rights to a location which could constitute a
System Element Location in a timely or economic manner.  When making changes to
the RF Engineering plan the Vendor must take into account the Site Acquisition
already completed by the Owner.

          (c)  In accordance with the Project Milestones set forth on Exhibit A1
and the requirements and criteria set forth in Exhibit B1, within five (5) days
of the Owner achieving Site Acquisition Substantial Completion within any given
System Area (the "Final RF Review Period"), the Owner and the Vendor will use
their best efforts to agree on a final System Element Location count (the "Final
Site Count") and a final RF Engineering plan (the "Final RF Engineering Plan")
for such System Area upon which the PCS System for such System Area will be
built by the Vendor.  Failure of the Owner and the Vendor to reach satisfactory
agreement on a Final Site Count and/or a Final RF Engineering Plan for any given
System Area within the Final RF Review Period will automatically result in the
referral of any such disagreement to the most senior RF engineers of both the
Owner and the Vendor for their review and resolution within five (5) days after
the end of any such Final RF Review Period.  If the senior RF engineers fail to
resolve any such disagreement within the extended five (5) day resolution
period, the disagreement shall automatically be referred for resolution in
accordance with subsection 23.1.  It is understood by the Parties that during
the period of any such disagreement and the resolution thereof in accordance
with the Contract, the Work on such PCS System, to the extent possible, will be
ongoing and that Substantial Completion on such PCS System cannot be achieved
without agreement by the Parties on a Final RF Engineering Plan and/or a Final
Site Count for such PCS System and/or System Area.

     (d)  If the Owner reasonably determines that the Vendor has not provided
sufficient ETA to resolve any E1 Emergency Condition or E2 Emergency Condition
on a timely basis, the Owner will be entitled to withhold all payments with
respect to the affected PCS System then due or outstanding prior to the date of
such determination until such time as adequate ETA is provided to the Owner to
resolve such Emergency Condition.

     (e)  If an E1 Emergency Condition or an E2 Emergency Condition exists in a
PCS System prior to Final Acceptance of such PCS System the Vendor must deliver
to the Owner each Software Upgrade and each Equipment Upgrade developed by or on
behalf of the Vendor to resolve any E1 Emergency Condition or E2 Emergency
Condition promptly following completion of development of such Software Upgrades
or promptly following availability of such Equipment Upgrades but in no event
later than forty-eight (48) hours following such completion or such development
of such Software Upgrades or availability of such Equipment Upgrades.

     (f)  The term Non-Emergency Services includes providing to the Owner any
requested technical assistance and support, remote monitoring and outage review
consultation and the handling of Customer Service Requests ("CSR").

     (g)  Technical assistance and support must be provided for the purpose of
resolving non-emergency problems defined below as "P1 Major Condition", "P2
Significant Problem" and "P3 Minor Problem" which are reported to the Vendor.

                         (i)   P1 Major Condition means any non-emergency
               failure of specific features or functions of the System, any PCS
               System and/or any Product that restricts its operations, but does
               not render the System, any PCS System and/or any Product
               inoperable, impact traffic capacity or coverage or require
               significant manual intervention for the System, any PCS System
               and/or any Product to operate properly and in accordance with its
               applicable Specifications.  These events will include loss of
               diagnostic capabilities and/or loss of reporting functions.

                         (ii)   P2 Significant Problem means any non-emergency
               intermittently occurring problem related to specific primary
               functions or features and/or any inoperable secondary functions,
               which does not have a significant adverse effect on the overall
               performance of the System, any PCS System and/or any Product.
               By-pass or work around procedures must be used to alleviate such
               P2 Significant Problem until it is corrected.

                         (iii)    P3 Minor Problem means any non-emergency
               problem that does not affect the performance or functions of the
               System, any PCS System
<PAGE>

                                                                              35

               and/or any Product, and, despite such problem, the System, any
               PCS System and/or any Product is fully operable without
               restrictions. Such P3 Minor Problems may include documentation
               inaccuracies, cosmetics, minor requests for changes or
               maintenance requests.  The Vendor will resolve such P3 Minor
               Problems during the next available scheduled Software Upgrade or
               Equipment Upgrade.

     (h)  Should a non-emergency problem remain unresolved for the period or

     Non-emergency problems referred to the Vendor as a CSR will be resolved
based upon the priority assigned to them as determined by the Owner or as
mutually agreed by the Parties, and to the extent possible will be incorporated
into the next scheduled Software Release or Equipment Upgrade.

     2.26.4  ETA and CSR.  In the event that emergency or non-emergency
             -----------
technical support provided from the Vendor's technical support center is not
sufficient to resolve an E1 Emergency Condition or an E2 Emergency Condition, a
P1 Major Condition or a P2 Significant Problem, the Vendor must send a
technically qualified person or persons to the site of such emergency condition
or problem to assist the Owner's employees in solving such condition or problem.
The Vendor's technically qualified person or persons must be on-site within
twelve (12) hours after notification to the Vendor by the Owner, or at such
later time as may be determined by the Owner.  A CSR will be submitted by the
Owner to request a repair of the emergency condition or the non-emergency
problem, or to request the addition of a Software or Equipment Upgrade or other
Software or Equipment Feature Enhancement.  The Owner's CSRs will define the
condition or problem and state whether the Owner considers the CSR to be for a
Software/Equipment Upgrade or Software/Equipment Enhancement.  Changes to the
System or any PCS System resulting from CSRs must be fully

                                                                              36

tested and accepted in accordance with the Specifications.  The Vendor must
respond to the submission of a CSR by the Owner within five (5) business days,
acknowledging receipt of the CSR, confirming or denying agreement with the
Owner's assessment of whether the CSR may be considered a Software or Equipment
Upgrade or a Software or Equipment Feature Enhancement and summarizing the
Vendor's intended actions to handle the CSR.  A CSR may result in System fixes,
or enhancements, resulting in Product modifications reasonably acceptable to the
Owner.

     2.27  Review of Contract Documents.  The Vendor has examined in detail and
           ----------------------------
carefully studied and compared the Contract Documents with all other information
furnished by the Owner as of the Effective Date and has promptly reported to the
Owner any material errors, inconsistencies or omissions so discovered or
discovered by any of the Subcontractors.  The Vendor will not prosecute any
Major Portion of the Work knowing that it involves a material error,
inconsistency or omission in the Contract Documents without prior written notice
to and approval by the Owner.  If for any reason the Vendor violates this
subsection 227, the Vendor will, in addition to being subject to any other
remedies of the Owner and, in such case, will be deemed to have waived any
claims for an adjustment in any of the Specifications and/or System Standards
which results directly from any such error, inconsistency or omission.  This
subsection 227 does not, nor will be deemed to, in any manner limit the terms
of subsection 2.38.

     2.28  Licenses, Permits and Approvals.  Except as otherwise provided for
           -------------------------------
herein with respect to Site Acquisition, Microwave Relocation and Network
Interconnection, any Applicable Permits required by any Government Entity
relating to the manufacture, importation, re-exportation, safety or use of the
Products, the System or any PCS System throughout North America or in any state,
province or any political sub-division thereof will be the sole responsibility
of the Vendor.  Prior to the commencement of any Work and/or other activities by
the Vendor or any of its Subcontractors in connection with or pursuant to this
Contract, the Vendor will furnish the Owner with evidence that such Applicable
Permits have been obtained and are in full force and effect to the extent that
Applicable Permits are necessary for the commencement or undertaking of such
activities, and from time to time thereafter the Vendor, upon the reasonable
request of the Owner, will provide such further evidence as the Owner will deem
reasonably necessary.

     2.29  Eligibility under Applicable Laws and Applicable Permits.  The Vendor
           --------------------------------------------------------
will be responsible for ensuring that the Vendor and its Subcontractors are and
remain eligible under all Applicable Laws and Applicable Permits to perform the
Work under this Contract in the various jurisdictions involved.

     2.30  Customs Approvals.  The Owner agrees to reasonably assist, so long as
           -----------------
such assistance will not involve the incurrence of any costs or expenses by the
Owner, the Vendor to obtain and maintain (i) Applicable Permits for importation
or re-exportation of the Products on a duty and customs free basis and (ii)
entry or work permits, visas or authorizations required for personnel engaged by
the Vendor to perform Work under this Contract.

     2.31  Owner Participation.  In addition to the right of observation
           -------------------
contained in subsection 9.4 hereof, the Owner will be entitled to participate in
the Vendor's research and development activities (subject to the reasonable
acceptance of the Vendor) and product development and testing activities
pursuant to this Contract; provided that such observation will not affect the
                           --------
Vendor's responsibilities and warranties hereunder and will not otherwise
interfere with the Vendor's research and development activities.

     2.32  New Development Advisory Board.  In order to accommodate the Owner's
           ------------------------------
participation pursuant to this Contract, including, without limitation, pursuant
to subsections 2.11 and 2.31, the Owner and the Vendor will establish an NDAB
within sixty (60) days of the Effective Date.  The purpose of the NDAB will be
to review the development requirements and high level development milestones, to
ensure that the Vendor understands the Owner's requirements for each PCS System,
the System and/or any extensions thereto including, without limitation, any
subsequent Products and/or enhancements.  The NDAB will provide an executive
forum to discuss product ideas, Owner requirements and its recommended
development prioritization for improved infrastructure-based subscriber features
and System features, functions and capabilities.  The focus of the NDAB will be
on System features and services, new CDMA Products, System enhancements,
critical operational issues, future developments beyond CDMA cellular without
the need for System additions and on such other matters as the Parties mutually
agree upon from time to time.  Nothing contained in this subsection 2.32 will in
any way limit and/or modify the Owner's ability to enforce its rights under this
Contract and/or the Contract Documents or to otherwise maintain contacts with
the Vendor in any other way it sees fit.

     2.33  Market Development Manager.  The Vendor will provide a market
           --------------------------
development manager to coordinate the efforts of the Vendor in meeting its
obligations relating to the NDAB who will specifically focus on new Products,
CDMA services and features.  Such market development manager must be
knowledgeable in CDMA technology and the Owner's System and must work closely,
and on a regularly scheduled basis, with the Owner's senior engineering and
marketing personnel on feature development, feature roll-out, future road maps
for CDMA Products, and any other marketing aspect of providing PCS that the
Owner believes is beneficial to the System and/or any PCS System at such time.
The Vendor's market development manager and the manager's staff will serve as
the Owner's direct liaison with the Vendor to ensure that the Vendor's product
development teams are focusing on the Owner's priorities as described to the
Vendor by the Owner from time to time either through the NDAB or by any other
means acceptable to the Parties.

     2.34  Further Assurances.  The Vendor will execute and deliver all further
           ------------------
instruments and documents, and take all further action, including, but not
limited to, assisting the Owner in filing notices of completion with the
appropriate state, provincial and local lien recording offices, that may be
necessary or that the Owner may reasonably request in order to enable the Vendor
to complete performance of the Work or to effectuate the purposes or intent of
this Contract.

     2.35  Liens and Other Encumbrances.  (a)  In consideration of the mutual
           ----------------------------
undertakings herein and other good and valuable consideration the receipt and
sufficiency of which is hereby acknowledged, the Vendor:

          (i) covenants and agrees to protect and keep free the System and/or
     any PCS System and any and all interests and estates therein, and all
     improvements and materials now or hereafter placed thereon under the terms
     of this Contract, from any and all claims, liens, charges or encumbrances
     of the nature of mechanics, labor or materialmen liens or otherwise arising
     out of or in connection with performance by any Subcontractor, including
     services or furnishing of any materials hereunder, and to promptly have any
     such lien released by bond or otherwise;

          (ii) give notice of this subsection 2.35 to each Subcontractor before
     such Subcontractor furnishes any labor or materials for the System and/or
     any PCS System; and

          (iii)    make any and all filings reasonably requested by the Owner in
     order that the Owner may take advantage of the relevant local mechanics'
     lien waiver procedures with respect to mechanics' liens of any such
     Subcontractor and the Owner will cooperate in helping the Vendor to fulfill
     its obligation under this clause (iii) to the extent necessary.

     (b)  If any laborers', materialmen's, mechanics', or other similar lien or
claim thereof is filed by any Subcontractor, the Vendor will cause such lien to
be satisfied or otherwise discharged, or will file a bond in form and substance
satisfactory to the Owner in lieu thereof within ten (10) business days.  If any
such lien is filed or otherwise imposed, and the Vendor does not cause such lien
to be released and discharged forthwith, or file a bond in lieu thereof, then,
without limiting the Owner's other available remedies, the Owner has the right,
but not the obligation, to pay all sums necessary to obtain such release and
discharge or otherwise cause the lien to be removed or bonded to the Owner's
satisfaction from funds retained from any payment then due or thereafter to
become due to the Vendor.

     (c)  The Owner reserves the right to post or place within the System and/or
any PCS System notices of non-responsibility or to do any other act required by
Applicable Law, to exempt the Owner and the System from any liability to third
parties by reason of any work or improvements to be performed or furnished
hereunder; provided that failure by the Owner to do so will not release or
           -------- ----
discharge the Vendor from any of its obligations hereunder.

     2.36  Forecasting and Ordering.  Throughout the Term of this Contract, on a
           ------------------------
quarterly basis commencing on the Effective Date, the Owner will provide the
Vendor with rolling twelve-month forecasts of its ongoing Product and Service
requirements.  Upon the review and reasonable acceptance of such forecasts by
the Vendor pursuant to the terms of this Contract, the Owner will have the
right, but not the obligation, to confirm to the Vendor its orders for the
Products and Services set forth in such forecasts pursuant to the Owner's
delivery to the Vendor of formal written orders specifying the Products and/or
Services to be purchased in connection with the terms of this Contract.  The
Vendor's obligation to deliver
<PAGE>

                                                                              39

in accordance with accepted forecasts will be subject to receipt of the Owner's
orders not later than eighty-four (84) days prior to delivery of commercially
available MSC Equipment and forty-two (42) days prior to delivery of
commercially available BTS Equipment; provided, however, that nothing contained
                                      --------  -------
in this subsection 2.36 will in any way limit and/or modify the Vendor
obligations under this Contract to deliver Products and Services and to
otherwise do the Work in accordance with the Project Milestones set forth in
Exhibit A pursuant to the terms of this Contract.

     2.37  Microwave Relocation; Network Interconnection.  (a) The Vendor will
           ---------------------------------------------
not be responsible for Microwave Relocation within the System.  Unless otherwise
waived by the Owner, however, completion of Microwave Relocation in any given
System Area will be a prerequisite to the commencement of the Substantial
Completion testing to be performed by the Vendor in accordance with Exhibit B3
in such System Area.  The Owner may at its option choose instead to modify the
System performance criteria as set forth in Exhibit F by way of a Change Order
in order to account for the failure to fully and/or satisfactorily complete
Microwave Relocation in any such System Area such that Substantial Completion
testing in accordance with the requirements of Exhibit B3 may proceed.
Notwithstanding anything stated herein to the contrary (other than clause (b)
below), the Owner's failure and/or inability to fully complete Microwave
Relocation in any such System Area within eighteen (18) months of Milestone M6
(as set forth in Exhibit A1) (the "Microwave Delay Period") will entitle the
Vendor to otherwise commence Substantial Completion testing for the PCS System
in such System Area in accordance with Exhibit B3.  Pursuant to the requirements
of Exhibits A1, B1 and B3 with respect to any PCS System within the System the
Owner may upon the prior written request of the Vendor consent (such consent not
to be unreasonably withheld) to extend the scheduling of the Vendor's
Substantial Completion testing by not more than an additional thirty (30) days
pursuant to Milestone M8 in the event that more than twenty-five percent (25%)
of the System Element Sites in such PCS System as set forth in the Final Site
Count for such PCS System require Vendor optimization pursuant to Exhibit B1
that was otherwise delayed due to incomplete Microwave Relocation in such PCS
System immediately prior to the date scheduled for Substantial Completion
testing pursuant to Milestone M8.

     (b) The Vendor will not be responsible for Network Interconnection within
the System.  Unless otherwise waived by the Owner, completion of Network
Interconnection in any given System Area will be a prerequisite to the
commencement of the Substantial Completion testing to be performed by the Vendor
in accordance with Exhibit B3 in such System Area.  Notwithstanding anything
stated herein to the contrary (other than clause (a) above), if the Owner fails
to fully complete Network Interconnection in any such System Area within ninety
(90) days after Milestone 6 (as set forth on Exhibit A1), the Vendor will be
entitled to commence Substantial Completion testing for the PCS System in such
System Area in accordance with Exhibit B3.

     2.38  Vendor To Inform Itself Fully; Waiver of Defense.  (a)  The Vendor
           ------------------------------------------------
will be deemed to have notice of and to have fully examined and approved the
Specifications and all other documents referred to herein, and all drawings,
specifications, schedules, terms and conditions of this Contract, regulations
and other information in relation to this Contract
<PAGE>

                                                                              40

and/or the Contract Documents and/or any amendments, modifications or
supplements thereto at any time on or after the Effective Date and to have fully
examined, understood and satisfied itself as to all relevant information of
which the Vendor is aware or should have been aware and which is relevant as to
the risks, contingencies and other circumstances which could affect this
Contract and in particular the installation of the System, any PCS System or any
part thereof.  The Owner, its directors, officers, employees and agents and all
of them have no liability in law or equity or in contract or in tort with
respect to any such specifications, drawings, information, risks, contingencies
or other circumstances.

     (b) The fact that the Owner may have prepared or taken part in the
preparation of Specifications, documents, drawings, Engineering, designs,
specifications, schedules, terms or conditions, or may have designated
particular types of Products and/or Services to be furnished hereunder or
designated particular manufacturers or suppliers of Products or Services, or may
have taken part in the designation of any particular Subcontractor(s) or
subcontractor(s), or given vetoes or approvals with respect to the Work, or
otherwise become involved in the Work, will not give rise to any claim by the
Vendor or any Subcontractor or any defense to any warranty or other claims
asserted against the Vendor or any Subcontractor to the extent any such claim or
defense arises out of any information, specifications, drawings, documents or
other information, which the Vendor is deemed to have had notice of pursuant to
subsection 238(a) above and with respect to any such information arising after
the Effective Date which the Vendor had a reasonable opportunity to review.

     2.39  CMI/HIC.  From time to time throughout the Term of this Contract the
           -------
Parties may mutually agree as to the incorporation and integration of CMI/HIC
into the System in accordance with Exhibit D.

Effective Date and during the term of this Contract, the Owner may, upon fifteen
(15) days' prior written notice to the Vendor, designate any Person which is not
an Initial Affiliate as an "Additional Affiliate"; provided that the Vendor will
                                                   -------- ----
have a reasonable opportunity to review and approve such designation, such

and/or supply of PCS CDMA wireless technology; and provided, further, that (x)
                                                   --------  -------
the Owner, any Partner or any Initial Affiliate has at least a ten percent (10%)
equity ownership in such Person, (y) such Person is controlled by or under the
common control with the Owner, any Partner or any Initial Affiliate or (z) there
exists between the Owner and such Person an Additional Affiliate Arrangement.
<PAGE>

                                                                              41

     3.2  Agreements with Initial Affiliates.  During the term of this Contract,
          ----------------------------------
the Owner will have the right, but not the obligation, to require that the
Vendor enter into separate agreements with any Initial Affiliate designated by
the Owner (each, an "Initial Affiliate Agreement") for the supply of Products
and Services on similar terms and conditions as those set forth herein that
relate to the initial build-out of the Initial System as set forth on Schedule
4; provided that the Vendor will not be required to include in any Initial
   -------- ----
Affiliate Agreement any provisions substantially similar to those set forth in
Section 15 and subsections 2.5, 21.1, 24.1 and 27.5; and provided further that
                                                         -------- -------
after the date on which Final Acceptance of the last PCS System to reach Final
Acceptance has occurred, Initial Affiliate Agreements (whether or not executed
prior to such date) need not contain or retain substantially the same terms and
conditions as those set forth herein, except for those terms and conditions
related to pricing and warranties as are then available to the Owner pursuant to
this Contract.  Any Initial Affiliate that enters into an Initial Affiliate
Agreement with the Vendor will have the right to choose among the Products and
Services offered to the Owner under this Contract solely for use within the
Nationwide Network.

     3.3  Agreements with Additional Affiliates.  During the term of this
          -------------------------------------
Contract, the Owner will have the right, but not the obligation, to require that
the Vendor enter into separate agreements with any Additional Affiliate
designated by the Owner (each, an "Additional Affiliate Agreement") for the
supply of Products and Services at similar price and warranty terms as are then
available to the Owner pursuant to the terms of this Contract.  The Vendor must
enter into good faith negotiations for the establishment of such Additional
Affiliate Agreements with any such Additional Affiliate promptly upon the
designation of such Additional Affiliate by the Owner and upon notice to the
Vendor that such Additional Affiliate desires to enter into an Additional
Affiliate Agreement.  Any Additional Affiliate that enters into an Additional
Affiliate Agreement with the Vendor will have the right to choose among the
Products and Services offered to the Owner under this Contract solely for use
within the Nationwide Network.

     3.4  Affiliate Rights.  Notwithstanding anything herein contained to the
          ----------------
contrary, Affiliates will not be deemed third party beneficiaries to this
Contract or otherwise have any rights hereunder.  Only the Owner may designate a
Person as an Affiliate in accordance with the terms of this Section 3 and only
the Owner has the right and/or the ability to enforce any rights hereunder
against the Vendor.


     SECTION 4  SUBCONTRACTORS

     4.1  Subcontractors.  The Vendor will select Subcontractors in connection
          --------------
with the performance of the Work such that all Products and Services provided by
any such Subcontractors meet the System Standards and reliability and
performance requirements set forth in this Contract.  Regardless of whether or
not the Vendor obtains approval from the Owner of a Subcontractor or whether the
Vendor uses a Subcontractor recommended by the Owner, use by the Vendor of a
Subcontractor will not, under any circumstances:  (i) give rise to any claim by
the Vendor against the Owner if such Subcontractor breaches its subcontract or
contract with the Vendor; (ii) give rise to any claim by such Subcontractor
against the
<PAGE>

                                                                              42

Owner; (iii) create any contractual obligation by the Owner to the
Subcontractor; (iv) give rise to a waiver by the Owner of its rights to reject
any Defects or Deficiencies or Defective Work; or (v) in any way release the
Vendor from being solely responsible to the Owner for the Work to be performed
under this Contract.

     4.2  The Vendor's Liability.  The Vendor is the general contractor for the
          ----------------------
Work and remains responsible for all of its obligations under this Contract,
including the Work, regardless of whether a subcontract or supply agreement is
made or whether the Vendor relies upon any Subcontractor to any extent.  The
Vendor's use of Subcontractors for any of the Work will in no way increase the
Vendor's rights or diminish the Vendor's liabilities to the Owner with respect
to this Contract, and in all events, except as otherwise expressly provided for
herein, the Vendor's rights and liabilities hereunder with respect to the Owner
will be as though the Vendor had itself performed such Work.  The Vendor will be
liable for any delays caused by any Subcontractor as if such delays were caused
by the Vendor.

     4.3  No Effect of Inconsistent Terms in Subcontracts.  The terms of this
          -----------------------------------------------
Contract shall in all events be binding upon the Vendor regardless of and
without regard to the existence of any inconsistent terms in any agreement
between the Vendor and any Subcontractor whether or not and without regard to
the fact that the Owner may have directly and/or indirectly had notice of any
such inconsistent term.

     4.4  Assignability of Subcontracts to Owner.  The Vendor will use its best
          --------------------------------------
efforts to ensure that each material agreement between the Vendor and a
Subcontractor must contain a provision stating that, in the event that the
Vendor is terminated for cause, convenience, abandonment of this Contract or
otherwise, (i) each Subcontractor will continue its portion of the Work as may
be requested by the Owner and (ii) such agreement permits assignment thereof
without penalty to the Owner and, in order to create security interests, to the
Other Vendors, in either case at the option of the Owner and for the same price
and under the same terms and conditions as originally specified in such
Subcontractor's agreement with the Vendor.  Furthermore, the Vendor will use its
best efforts to ensure that each material agreement between the Vendor and a
Subcontractor contains a provision stating that such agreement may be made
available in whole or in part to the Owner at its reasonable request without
causing the violation and/or breach of any such agreement.  In the event the
Vendor is unable to ensure each such material Subcontractor agreement complies
with all of the requirements of this subsection 4.4 to the Owner, the Vendor
will notify the Owner of its inability to do so prior to executing such
arrangement with such Subcontractor and the Vendor will provide the Owner a
reasonable opportunity to determine whether it requires any such requirement in
question and if the Owner determines in its reasonable opinion that it in fact
requires such requirement the Vendor will not execute such Subcontractor
agreement without first obtaining the prior written consent of the Owner.

     4.5  Removal of Subcontractor or Subcontractor's Personnel.  The Owner has
          -----------------------------------------------------
the right at any time to require removal of a Subcontractor and/or any of a
Subcontractor's personnel from Work on the System upon reasonable grounds and
reasonable prior written notice to the Vendor.  The exercise of such right by
the Owner will have no effect on the provisions of subsections 4.1 and 4.2.

                                                                              43

     4.6  Subcontractor Insurance.  The Vendor must require all Subcontractors
          -----------------------
to obtain, maintain and keep in force during the time they are engaged in
providing Products and Services hereunder adequate insurance coverage consistent
with Section 18 and Schedule 6 (provided that the maintenance of any such
Subcontractor insurance will not relieve the Vendor of its other obligations
pursuant to Section 18 and Schedule 6).  The Vendor will, upon the Owner's
request, furnish the Owner with evidence of such insurance in form and substance
reasonably satisfactory to the Owner.  To the extent requested by the Owner all
such insurance will be subject to the Owner's reasonable approval.  All
Subcontractors must be of bondable financial condition.

     4.7  Review and Approval not Relief of Vendor Liability.  Any inspection,
          --------------------------------------------------
review or approval by the Owner permitted under this Contract of any portion of
the Work by the Vendor or any Subcontractor will not relieve the Vendor of any
duties, liabilities or obligations under this Contract.

     4.8  Vendor Warranties.  Except as otherwise expressly provided in Section
          -----------------
17, the warranties of the Vendor pursuant to Section 17 will be deemed to
apply to all Work performed by any Subcontractor as though the Vendor had itself
performed such Work.  Except as otherwise specifically provided in Section 17,
the Parties agree that such warranties will not be enforceable merely on a
"pass-through" basis.  The Owner may, but shall not be obligated to, enforce
such warranties of any Subcontractor to the extent that the Owner determines
that the Vendor is not paying and/or performing its warranties; provided that
                                                                -------- ----
any such election by the Owner will not relieve the Vendor from any obligations
or liability with respect to any such warranty.

     4.9  Payment of Subcontractors.  The Vendor must make all payments to all
          -------------------------
Subcontractors (except in the case of legitimate disputes between the Vendor and
any such Subcontractor arising out of the agreement between the Vendor and such
Subcontractor) in accordance with the respective agreements between the Vendor
and its Subcontractors such that Subcontractors will not be in a position to
enforce liens and/or other rights against the Owner, the System or any part
thereof.


     SECTION 5  TERM OF CONTRACT

     5.1  Initial Term.  The initial term of this Contract (the "Initial Term")
          ------------

                                                                              44

     SECTION 6  PRICES AND PAYMENT

     6.1  Prices.  The prices for the Work to be performed pursuant to this
          ------
Contract (collectively, the "Contract Price") are as set forth on Schedules 2
and 3, subject to the price variation provisions contained on Schedule 2.
Prices for the Work not set forth on Schedules 2 or 3, if not otherwise set
forth in this Contract, will be no greater than the Vendor's best list prices
then in effect at the time of ordering by the Owner and at discounts otherwise
provided to the Owner pursuant to the terms of this Contract.

     6.2  Price Reduction.  The Contract Price will be reduced by all amounts
          ---------------
saved as a result of Engineering changes suggested by the Owner which are
incorporated into the Specifications by the Vendor provided that the Vendor
                                                   --------
reasonably believes that such changes will not make it impossible or
impracticable for it to comply with any of its obligations under this Contract.
Any reduction in Contract Price pursuant to the preceding sentence will be
agreed upon promptly by the Owner and the Vendor.  Failure of the Parties to
mutually agree to such price reductions within ten (10) days from the date the
Owner delivered written notice to the Vendor of the need for such price
reduction due to incorporated Engineering changes will result in the automatic
reference of such matter to dispute resolution in accordance with subsection
23.1.  During the pendency of any such dispute resolution prices payable
pursuant to subsection 6.1 will be payable by the Owner to the Vendor at the
reduced level pursuant to this subsection 6.2 so long as such dispute resolution
pursuant to this subsection 6.2 does not exceed thirty (30) days; provided that
                                                                  -------- ----
in the event such dispute resolution exceeds thirty (30) days prices in question
pursuant to this subsection 6.2 will revert back to the level prior to the
Owner's invocation of this subsection 6.2 for the remaining period of any such
dispute resolution.  If in accordance with subsection 23.1 such dispute
resolution results in a finding that such price reduction was not in fact
justified then the Owner will refund to the Vendor the amounts that would
otherwise have been payable to the Vendor during the pendency of such dispute
resolution.

portion of such Work.  By appropriate agreement in each Subcontractor's
agreement with the Vendor, the Vendor will require such Subcontractor to make
payments to sub-Subcontractors and materialmen in a similar manner.  The Owner
shall have no obligations to pay any amount other than for Facilities
Preparation Services performed and shall have no obligations to pay any other

Delay Penalties accrued pursuant to this subsection 15.2(a) will be offset
against the payment to be made by the Owner to the Vendor upon Substantial
Completion of the PCS System to which such interim delay relates. The Interim
Delay Penalty applicable to each of Project Milestones M3 and M4 as set forth on
Exhibit A will be [   ]

     (b)  To the extent that the Vendor is responsible for Interim Delay
Penalties pursuant to subsection 15.2(a) such penalties will be credited back to
the Vendor by the Owner to the extent that (i) the Vendor successfully achieves
the Interim Milestone subject to delay within thirty (30) days of the date
scheduled therefor pursuant to the terms hereof and Exhibit A and (ii) such
interim delay does not otherwise materially adversely affect the Owner, such PCS
System and/or the System as a whole.  Any such reimbursement will be credited
back to the Vendor such that the Interim Delay Penalty otherwise offset against
the relevant Substantial Completion payment in accordance with subsection
15.1(a) above will be added back to such Substantial Completion payment to be
made to the Vendor by the Owner.  Interim Delay Penalties applicable to Interim
Milestones M6 and M7 within any PCS System in any Non-Designated System Area may
be assessed on the earliest date any such Interim Delay Penalties may be
retroactively calculated in accordance with subsection 2.7(b).

[   ]

     (b)  If any PCS System does not achieve Substantial Completion by the
Guaranteed Substantial Completion Date but the Owner nonetheless chooses (in its
sole discretion) to commence In Revenue Service in such incomplete PCS System
(such action in no way constituting the Owner's acceptance, express or implied,
of the System or such PCS System or any part thereof), then the Vendor will be
required to pay, on a daily basis, only that percentage of the daily Late
Completion Payment equal to that percentage of the geographic area to be
otherwise covered by such PCS System not otherwise placed in In Revenue Service
by the Owner.

     (c)  In the event of a change in the Contract Price pursuant to subsections
6.2, 7.3 or 27.16 during the Term of this Contract from the amount originally
set forth in this Contract pursuant to Section 6 the per diem amount of Late
Completion Payments set forth above will be increased or decreased, as
appropriate, by an amount equal to the increase or decrease in the Owner's per
diem interest payment obligation resulting from any change in the amount of debt
incurred or to be incurred by the Owner related to such change in the Contract
Price.

     (d)  Late Completion Payments, including any portions of such payments
payable in accordance with paragraphs (a) and (b) above, will be accrued during
the Completion Cure Period and offset against payments otherwise due to the
Vendor upon the achievement of Substantial Completion pursuant to the terms of
subsection 6.3.  If the Vendor fails to achieve Substantial Completion within
forty-five (45) days, or thirty (30) days in the event the Owner chooses to
commence In Revenue Service as described in clauses (b) and (c) to this
subsection 15.3, of the Guaranteed Substantial Completion Date for any reason
other than primarily because of (i) a Force Majeure event pursuant to Section
16 or (ii) the direct and explicit act or omission of the Owner, then the Owner
will have the option to terminate this Contract without any penalty or payment
obligation (other than payment obligations under this Contract outstanding as of
the date of any such termination; provided that any such amounts payable by the
                                  -------- ----
Owner will not include any amounts that would have been payable to the Vendor
only upon Substantial Completion or Final Acceptance).  For the purposes of
determining amounts owed to the Owner by the Vendor pursuant to the terms of
this subsection 15.3, the term "Contract Price" as applicable to any given PCS
System will mean the total cost of such PCS System as incurred by the Owner and
payable to the Vendor or any of its Subcontractors for any and all Products and
Services provided or performed by the Vendor or any of its Subcontractors in
connection with the construction and operation of such PCS System pursuant to
the terms of this Contract other than Facilities Preparation Services performed
within such PCS System; provided that in the event of any delay in the Vendor's
                        -------- ----
performance in a given PCS System subject to the damages set forth in this
subsection 15.3 that is due in whole or in part, directly or indirectly, to a
delay in satisfactory completion of the Facilities Preparation Services within
such PCS System to be performed by the Vendor or any of its Subcontractors
pursuant to the terms of this Contract and in accordance with
<PAGE>

                                                                              60

Exhibit E, the calculation of the Contract Price will include the full cost of
all Facilities Preparation Services performed by the Vendor or any of its
Subcontractors in such PCS System.  In any given PCS System the aggregate amount
of all Interim Delay Penalties and Late Completion Payments owed to the owner
pursuant to this Section 15 will in no event exceed thirty-five percent (35%) of
the Contract Price applicable to such PCS System.

     15.4  PCS System and System Element Delivery Prioritization.  (a)  In no
           -----------------------------------------------------
event will the Vendor be required under the terms of this Contract to deliver to
the Owner Products on a time schedule and/or in amounts greater than that set
forth on Exhibit A2.

          (b)  In the event the Vendor is required pursuant to the progression
of the Work and the Project Milestones in every PCS System within the System to
deliver an amount of Products equal to or more than ninety-five percent (95%) of
the amount of Products indicated for delivery by the Vendor in the fourth
quarter of 1996 as set forth on Exhibit A2, the Vendor will have the right, but
not the obligation, pursuant to this subsection 15.4, to request in writing that
the Owner re-prioritize up to three (3) PCS Systems within the System and in
such event the Owner will delay the Project Milestones to be achieved by the
Vendor in each such PCS System as the Owner will designate to the Vendor, in its
sole and absolute discretion, for a period not in excess of ninety (90) days
without any penalty to the Vendor under this Section 15.

          (c)  The Owner will use reasonable efforts to inform the Vendor by
5:00 p.m. on April 15, 1996 which System Areas, of all of the System Areas set
forth on Schedule 4, it, in its sole and absolute discretion, has determined to
designate as the thirteen (13) System Areas which should receive priority as to
the build-out by the Vendor of the PCS Systems within such System Areas.  The
remaining four System Areas are the "Non-Designated System Areas" referred to
herein.  Any such notification provided pursuant to and in accordance with this
subsection 15.4(c) will in no way modify the Vendor's obligations under the
terms of this Contract; provided that any delay by the Owner in providing the
                        -------- ----
Vendor the notice described in this subsection 15.4(c) will result in day-for-
day delays in the Guaranteed Completion Dates applicable to the PCS Systems
within the Initial System (other than the PCS Systems in the Non-Designated
System Areas).


     SECTION 16  FORCE MAJEURE

     16.1  (a)  Either Party may make a claim for excusable failure or delay
with respect to any obligation of such Party under this Contract, except any
obligation to make payments when due.  Excusable failure or delay will be
allowed only in the event of an event of Force Majeure that is beyond the
reasonable control of the affected Person.  Notwithstanding the foregoing, the
Vendor will not be entitled to relief under this Section 16 to the extent that
any event otherwise constituting an event of Force Majeure results from the
negligence or fault of the Vendor or any Subcontractor, and the Owner will not
be entitled to relief under this Section 16 to the extent any event otherwise
constituting an event of Force Majeure results from the negligence or fault of
the Owner.

     (b)  The Party claiming the benefit of excusable delay hereunder must (i)
promptly notify the other Party of the circumstances creating the failure or
delay and provide a statement of the impact of such Party failure or delay and
(ii) use reasonable efforts to avoid or remove such causes of nonperformance,
excusable failure or delay.  If an event of Force Majeure prevents the Vendor
from performing its obligations under this Contract for a period exceeding sixty
(60) days, the Owner may, upon prior written notice to the Vendor, terminate
this Contract.

     (c)  The Party not claiming the benefit of excusable delay hereunder will
likewise be excused from performance of its obligations hereunder on a day-for-
day basis to the extent such Party's obligations are affected due to the other
Party's delayed performance.

     17.4  System Warranty.  The Vendor warrants that, for a period three (3)
           ---------------
years from the Final Acceptance of the last PCS System within the Initial System
(the "System Warranty Period"), the ongoing performance of each PCS System
together with all other PCS Systems within the System will conform with and
perform to the performance criteria set forth
<PAGE>

                                                                              63

Exhibit F as of the date of the Final Acceptance of such PCS System based on the
circumstances within such PCS System on such date.

     17.5  Breach of Warranties.  (a)  In the event of any breach of any of the
           --------------------
Warranties during any of the applicable Warranty Periods set forth in
subsections 17.1, 17.2, 17.3(a), 17.3(b), 17.3(c) and 17.4, the Vendor will, in
accordance with the terms of this Section 17,  promptly repair or replace the
defective or nonconforming Product or otherwise cure any Defects and
Deficiencies so that each PCS System and the System as a whole will perform in
accordance with the Specifications and Exhibit F.  If the Vendor fails to
promptly repair, replace and/or cure such defect, the Owner may, in addition to
exercising any other remedies available to it, itself cause such repair,
replacement and/or cure, at its option and at the sole cost and expense of the
Vendor.

     (b) The Vendor recognizes that the Owner may suffer injury and may be
damaged in an amount which will be difficult to determine with certainty as a
result of Outages resulting from causes attributable to the failure of the
Vendor's Products and/or Services to perform in accordance with the
Specifications. As used herein, "Outage" means an unscheduled loss of
functionality of the System or any PCS System defined as the loss of the
capability to originate or terminate [   ] or more of the active voice channels
then in service within the System or such PCS System for a period of time
exceeding [   ] minutes.

     (c) During the System Warranty Period, the Vendor will be liable to the
Owner for damages (the "Warranty Damages") for Outages that result from (i) the
failure of the Vendor's Equipment and/or Software to perform in accordance with
the Specifications, (ii) the failure of the Vendor to provide Services in
accordance with the Specifications applicable thereto, (iii) a Vendor procedural
error or (iv) inaccurate Technical Documentation, excluding marketing bulletins,
sales literature or other promotional materials provided by the Vendor to the
Owner. As used herein, "Vendor procedural error" means an error or improper
deviation from the Vendor's or its Subcontractors' procedures by, or
attributable to, the Vendor's personnel. Warranty Damages will be calculated
based upon [   ] for each Outage occurring in any given PCS System to the extent
such Outage exceeds [   ] from the time the Owner notified the Vendor of
such Outage (not including such first hour), plus [   ] per minute for each
minute the duration of the Outage exceeds one (1) hour from the time the Owner
notifies the Vendor of such Outage (not including such first hour).

     (d) In no event will the Vendor's liability for Warranty Damages pursuant
to this subsection 17.5 exceed [   ] with respect to each Outage in any given
PCS System. In addition, the Vendor's total liability for Warranty Damages
pursuant to this subsection 17.5 will not exceed [   ] per calendar year during
the Term of this Contract with respect to Outages in any given PCS System per
calendar year.

     (e)  Notwithstanding the foregoing, the Vendor will have no liability
pursuant to this subsection 17.5 for:

                                                                              64

                         (i)   Outages caused by a Force Majeure event as
               described in Section 16 other than to the extent that any of the
               Vendor's Products and/or Services resulting in such Outages
               should, in accordance with the Specifications and/or the Vendor's
               representations be able to withstand any such Force Majeure
               event;

                         (ii)   Outages resulting from a scheduled activity,
               including, but not limited to, System maintenance or Software or
               Equipment Upgrades, unless said Outage extends beyond the
               expected downtime, as provided in the Specifications applicable
               thereto, associated with such Equipment or Software maintenance
               Upgrades;

                         (iii)    alterations by the Owner and/or the Vendor at
               the Owner's request or otherwise pursuant to the terms of this
               Contract to the System and/or any PCS System, excluding normal
               maintenance or parameter changes as prescribed by the applicable
               Technical Documentation;

                         (iv)   Outages resulting from the Owner's, its
               subcontractors' or any third party's (if such third party is
               employed by the Owner) failure to follow the Technical
               Documentation;

                         (v)   Outages resulting from the gross negligence or
               willful misconduct of the Owner, or any of its employees, agents
               or contractors; or

                         (vi)   Outages resulting from failure of equipment or
               software not supplied by the Vendor or any Subcontractors or from
               the performance of services not performed by the Vendor or any
               Subcontractors.

     (f)  On or before the beginning of each quarter of each calendar year
during the Term of this Contract, the Owner shall provide the Vendor a written
report summarizing any Outages occurring during the previous calendar quarter.
The amount of any Warranty Damages shall be determined by the Owner as of the
end of the fourth quarter of each calendar year during the Term, for the
preceding four quarterly reporting periods during such Term.  The Owner will
notify the Vendor of any such Warranty Damages in writing.  Such Damages will be
payable in credits on future purchases under this Contract or otherwise if this
Contract is terminated for any reason within thirty (30) days of the occurrence.
Any disputes regarding the determination of the cause of an Outage or the amount
of any such Warranty Damages shall be resolved in accordance with the provisions
of Section 23.

     17.6  Repair and Return. (a)  If the Owner claims a breach of warranty
           -----------------
under subsections 17.1, 17.2, 17.3 or 17.4, it must notify the Vendor of the
claimed breach within a reasonable time after its determination that a breach
has in fact occurred.  The Owner will allow the Vendor to inspect the Products,
the Non-Essential Equipment, the Services or the System, as the case may be, on-
site, or, upon the Vendor's reasonable request and, subject to subsection
17.6(d) below, at the Vendor's sole expense: (i) with respect to Products,
return such Products to any of the Vendor's repair facilities located in North
America and listed on
<PAGE>

                                                                              65

Schedule 8, or (ii) with respect to Non-Essential Equipment, return such Non-
Essential Equipment to the Vendor for further return to the applicable third
party manufacturer.

          (b)  The Vendor agrees to commence work on all such Products, Non-
Essential Equipment, Services or any System Defect, as the case may be, or
Installation Defects as soon as practicable, but in no event later than twenty-
four (24) hours after notification of such defect, and, subject to subsections
17.6(e) and 17.6(f), the Vendor will cure such defect as promptly as
practicable.  During the Product Warranty Period and the Non-Essential Equipment
Warranty Period, electronic circuit board components of Equipment or Non-
Essential Equipment, as the case may be, will be repaired or replaced by the
Vendor.

          (c)  Failure of the System to function to the level of the performance
warranty as set forth in subsection 17.4 will result in the obligation of the
Vendor to promptly make whatever repairs, modifications, alterations, expansions
or to take any other action of any kind, including but not limited to the
provision of additional Products and/or Services, necessary to satisfactorily
fix that portion of the System causing such failure.

          (d)  All costs associated with (i) removing or disconnecting the
Products or the Non-Essential Equipment subject to the warranty claim pursuant
to the terms of this Section 17 from any other Products, the respective PCS
System or any part thereof or from other equipment, any other pcs system or any
part thereof to which they are attached or connected, or (ii) dismantling
surrounding Products, the respective PCS System or any part thereof or any other
equipment or other pcs system or any part thereof in order to so remove or
disconnect the Products or Non-Essential Equipment subject to such warranty
claim shall be borne by the Vendor throughout the applicable Warranty Period.
All packaging, shipping and freight charges incurred in connection with the
Vendor's obligations under this subsection 17.6 will be borne by the Vendor,
unless the Products or Non-Essential Equipment, as the case may be, returned are
not Defective or otherwise not covered by the Vendor's warranty pursuant to
subsections 17.1 and 17.2, in which case the Owner will pay for all such charges
between the Owner's point of origin and the Vendor's applicable repair facility
in North America.

          (e)  For routine warranty service, the Vendor will, during the
respective Warranty Period, ship replacement or repaired Products or Non-
Essential Equipment (or components thereof) within thirty (30) days of receipt
of the Defective Equipment or Non-Essential Equipment (or components thereof)
from the Owner.  In the event such replacement or repaired Products or Non-
Essential Equipment cannot be shipped within such time period, or if the Vendor
determines that due to the particular circumstances, on-site repairs or services
are required, the Vendor shall undertake such repairs or replacement services
on-site within thirty (30) days of notification of the warranty Defect by the
Owner.  In the event that the Vendor fails to repair or replace Defective
Products and/or Non-Essential Equipment within thirty (30) days from the Owner's
notice to the Vendor, then the Vendor shall be deemed to be in material breach
of its obligations pursuant to this Contract and the Owner shall be entitled to
receive a refund of all amounts previously paid to the Vendor for the Defective
Products or Non-Essential Equipment, and shall have no further obligation to pay
additional amounts in connection with the Defective Products or Non-Essential
Equipment.
<PAGE>

                                                                              66

The Owner shall return such Defective Products and Non-Essential Equipment to
the Vendor at the Vendor's sole cost and expense.

          (f)  For emergency warranty service situations, the Vendor will,
during the applicable Warranty Periods, use its best efforts to ship replacement
Products or Non-Essential Equipment (or components thereof) no later than twelve
(12) hours after notification of the warranty Defect by the Owner.  The Owner
shall ship the Defective Products or Non-Essential Equipment to the Vendor
within thirty (30) days of receipt of the replacement Products or Non-Essential
Equipment, as the case may be.  In the event the Vendor fails to receive such
Defective Products or Non-Essential Equipment within such thirty (30) day
period, the Vendor shall invoice the Owner for the replacement Products or Non-
Essential Equipment at the then-current price in effect therefor pursuant to the
terms of this Contract.  If in an emergency warranty service situation, the
Owner and/or the Vendor determines that due to the particular circumstances, on-
site technical assistance is necessary, the Vendor shall use its best efforts to
dispatch emergency service personnel to the site within twelve (12) hours of
notification of the warranty Defect by the Owner.  For the purpose of this
subsection 17.6, an emergency warranty service situation shall be deemed to
exist upon the occurrence of any E1 Emergency Condition or E2 Emergency
Condition.  The Vendor agrees to commence work on all Equipment, Non-Essential
Equipment, Facilities Preparation Services or any System defect, as the case may
be, or Installation defects materially impairing service to subscribers, System
performance, billing, administration and/or maintenance as soon as practicable,
but in no event later than twenty-four (24) hours after notification of such
defect, and the Vendor will cure such defect as promptly as practicable.

contrary, the Owner may withhold payments, if any, to the Vendor for the
purposes of offset of amounts owed to the Owner pursuant to the terms of this

Vendor is fully determined; provided, however, that the amount of any such
                            --------  -------
offset pursuant to this subsection 24.5 will not be greater than the amounts
otherwise owed to the Vendor and claimed hereunder.

     24.6  Costs.  In the event of a termination due to a Vendor Event of
           -----
Default, the Owner will be entitled to the costs in connection with finishing
the Work (exclusive of any Liquidated Damages already paid and/or owing to the
Owner upon termination of this Contract), and if such costs exceed the unpaid
balance of the Contract Price for such Work, the Vendor will be liable to pay
such excess to the Owner, provided that the Owner will use the same care as it
                          -------- ----
would otherwise use in light of the extraordinary circumstances contemplated
under this subsection 24.6.  The amount to be paid by the Vendor pursuant to
this subsection 24.6 will survive termination of this Contract and will be
subject to the limitations of liability in this Contract.

     24.7  Continuing Obligations.  Termination of this Contract for any reason

this Contract;

days after the Vendor has notified the Owner of its right and intent to so
terminate on account of such overdue amount;

     (d)  the Owner continuously and materially breaches subsection 11.1 or
subsection 27.19 notwithstanding the fact that the Vendor will have provided the

cure any such breaches; or

     (e)  except as otherwise provided in subsection 24.1 the Owner fails to
fulfill its Initial Commitment within five (5) years of the Effective Date for

to successfully attain Site Acquisition Substantial Completion in any given PCS
System or (iv) any event otherwise constituting a Force Majeure hereunder; or

materially and adversely affects the Vendor and/or its performance under this

Owner under this Contract for the purposes of this subsection 24.8(f) or (ii)
the failure and/or inability of the Owner to complete any such activities for
any reason whatsoever be deemed a breach of the Owner under the terms of this
Contract including, but not limited to, this subsection 24.8(f).

     24.9  Special Termination Events.  (a)  In the event that financing for the
           --------------------------
Owner's build-out of the initial phase of the Nationwide Network has not been
finalized with the Vendor and the Other Vendors on terms and conditions
reasonably satisfactory to the Owner, on or before one hundred and eighty (180)

Subcontractors pursuant to the specific terms of this Contract which had been
directly delivered to or performed for the Owner and/or any of its facilities or

to, the Project Milestones.  Any amounts owed by the Owner for Work done or
Products delivered by the Vendor during such interim one hundred and eighty
(180) day period (the "Financing Interim Period") not otherwise invoiced to the
Owner by the Vendor prior to the termination of such Financing Interim Period,
will be invoiced to the Owner by the Vendor within forty-five (45) days of such
termination pursuant to this subsection 24.9(a) and will be payable to the

connection with the establishment of and/or upgrade to its manufacturing,
personnel, engineering, administrative or other capacities and/or resources in
contemplation of or pursuant to its performance in accordance the terms of this

believes, in its reasonable opinion, that the financing for the System and/or
the Nationwide Network is not likely to be finalized by the end of any such
Financing Interim Period.  In the event of a termination pursuant to this
subsection 24.9(b) payment obligations incurred by the Owner for Work done by
the Vendor pursuant to the terms of this Contract will be payable by the Owner
to the Vendor on the same terms and  subject to the limitations set forth in
subsection 24.9(a) above.

     (c) If at any time after the Effective Date any material change shall have
occurred in any Applicable Law or in the interpretation thereof by any
Governmental Entity, or there shall be rendered any decision in any judicial or
administrative case, in either case which, in the reasonable opinion of the
Owner, would make the Owner's use of any part of any PCS System illegal or would
subject the Owner or any of its Affiliates to any material penalty, other
material liability or onerous condition or to any burdensome regulation by any
Governmental Entity or otherwise render the use of such PCS System economically
nonviable, then, with respect to such PCS System, or affected part thereof, or
with respect to the entire System if so affected, the Owner may terminate this
Contract without charge or penalty of any kind; provided that (i) the Owner
                                                -------- ----

ameliorate such change or decision to the extent possible or practical prior to
declaring such termination and (iii) the Owner, at the Vendor's request, gives

subject to the review and reasonable acceptance of the Owner.  No modification
to the Specifications will be made to the extent that performance is, was or
would have been suspended, delayed or interrupted for any other cause due to the
Vendor's fault or if the suspension had no effect on agreed upon performance
deadlines and/or Project Milestones set forth in this Contract.


     SECTION 26  MOST FAVORED CUSTOMER

     26.1  Most Favored Customer Status.  (a)  With respect to the Initial

context of the Initial System pursuant to the terms of this Contract), the Owner
will be deemed the Vendor's most important and favored Customer and will always
receive priority in terms of price, availability and quantity of CDMA 1900
Products, Engineering and Services. [ ] the Owner will receive Products,
Engineering and Services at prices and on payment terms no less favorable to the
Owner than those offered or available to any other Customer (other than Initial
Affiliates and/or Additional Affiliates pursuant to the terms of this Contract)
of the Vendor.

     (b)  On an annual basis throughout the Term of this Contract commencing on
the Effective Date the Vendor will be required to audit its pricing of all CDMA
1900 products, engineering and services provided to all of its Customers (other
than Initial Affiliates and/or Additional Affiliates pursuant to the terms of
this Contract) in the preceding calendar year and certify to the Owner in a
certificate executed by a duly authorized officer of the Vendor (the "MFC
Certificate") that the Owner has in fact received the prices, availability and
quantity of and on Products, Engineering and Services in accordance with the
terms of clause (a) above.  The annual MFC Certificate delivered to the Owner in
accordance with this subsection 26.1 will be subject to verification by an
independent, reputable and nationwide public accounting firm reasonably
acceptable to the Owner and at the sole cost and expense of the Vendor.

     (c)  To the extent that it is determined pursuant to clause (b) above that
the Vendor has not in fact complied with the terms of clause (a) above the Owner
will have thirty (30) business days from receipt of the MFC Certificate as
verified by the independent public accountant to provide the Vendor with a
written claim for Product and/or Engineering and/or Service pricing rebates on
future purchases under this Contract based upon the Owner's reasonable
calculation of the impact on the Owner of the Vendor's failure to comply with
clause (a) of this subsection 26.1.  To the extent the Vendor disagrees with any
such claim for such pricing rebates made by the Owner pursuant to this clause
(c) the Vendor will have the right within ten (10) business days of receiving
the Owner's written rebate claim to submit the Owner's claim and the Vendor's
written response thereto to an Independent Auditor who will have the authority
only to determine whether the Owner's calculation of the claimed pricing rebate
is fair and reasonable in light of the Vendor's non-compliance with the terms of
clause (a) above.  The Independent Auditor's determination must be made and
delivered to both the Vendor and the Owner within ten (10) business days of
receiving the

                                                                              81

request from the Vendor.  Such determination once made by the Independent
Auditor will be final and binding on the Parties and will not be subject to
further modification.

     27.16  Financing Parties Requirements.  The Vendor acknowledges that the
            ------------------------------
Owner represents that attainment of financing for construction of the Nationwide
Network may be subject to conditions that are customary and appropriate for the
providers of such financing.  Therefore, the Vendor agrees to execute promptly
any reasonable amendment to or modification of this Contract required by such
providers (including, without limitation, any pertinent industrial development
authority or other similar governmental agency issuing bonds for financing of
the System) in order to obtain such financing.  In the event that any such
amendment or modification materially increases the Vendor's risk or costs
hereunder, the Owner and the Vendor will negotiate in good faith to adjust the
Contract Price, and to equitably adjust such other provisions of this Contract,
if any, which may be affected thereby, to the extent necessary to reflect such
increased risk or costs.  Amendments or modifications not materially increasing
the Vendor's risk or costs will be made without charge by the Vendor.  The
Vendor will be responsible for and pay all costs as a result of the Vendor's or
its Subcontractors' failure to promptly comply with the request for any such
modification or amendment made by any provider of financing described in this
subsection.

     27.17  Owner Review, Comment and Approval.  To the extent that various
            ----------------------------------

evaluation, recommendation or approval, the Owner may at its option do so in
conjunction and/or consultation with the Vendor.  To the extent that this

designate the Engineer to submit, furnish, provide or deliver such items as the
Owner's agent therefor.  To the extent that various provisions of this Contract
provide that the Owner may order, direct or make requests with respect to
performance of the Work or is provided access to the System sites or any other
site, the Owner may at its option and upon written notice to the Vendor
authorize the Engineer to act as the Owner's agent therefor.  Upon receipt of
such notice, the Vendor shall be entitled to rely upon such authorization until
a superseding written notice from the Owner is received by the Vendor.

     27.18  Specifications.  The Owner acknowledges that parts of the
            --------------
Specifications are comprised of Specifications prepared by the Vendor and that
the Vendor contributed significantly to many other portions thereof.  The Owner
also acknowledges that, during the normal design, evolution and development
process, portions of the Specifications may appear in design and procurement
documents prepared by the Vendor in its normal course of business; provided,
                                                                   --------
however, that the Owner will have no liability for any third party claims for
- - - -------
contributor infringement or the like with respect to such Specifications
prepared by the Vendor or portions thereof to which the Vendor contributed
significant portions or use and the Vendor will hold the Owner harmless from any
such third party claims.

     27.19  Confidentiality.  (a) All information, including without limitation
            ---------------
all oral and written information, disclosed to the other Party is deemed to be
confidential, restricted and proprietary to the disclosing Party (hereinafter
referred to as "Proprietary Information").  Each Party agrees to use the
Proprietary Information received from the other Party only for the purpose of
this Contract.  Except as specified in this Contract, no other rights, and
particularly licenses, to trademarks, inventions, copyrights, patents, or any
other intellectual property rights are implied or granted under this Contract or
by the conveying of Proprietary Information between the Parties.  Proprietary
Information supplied is not to be reproduced in any form except as required to
accomplish the intent of, and in accordance with the terms of, this Contract.
The receiving Party must provide the same care to avoid disclosure or
unauthorized use of Proprietary Information as it provides to protect its own
similar proprietary information.  All Proprietary Information must be retained
by the receiving Party in a secure place with access limited to only such of the
receiving Party's employees or agents who need to know such information for
purposes of this Contract and to such third parties as the disclosing Party has
consented to by prior written approval.  All Proprietary Information, unless
otherwise specified in writing (i) remains the property of the disclosing Party,
(ii) must be used by the receiving Party only for the purpose for which it was
intended, and (iii) such Proprietary Information, including all copies of such
information, must be returned to the disclosing Party or destroyed after the
receiving Party's need for it has expired or upon request of the disclosing
Party, and, in any event, upon termination of this Contract.  At the request of
the disclosing Party, the receiving Party will furnish a certificate of an
officer of the receiving Party certifying that Proprietary Information not
returned to disclosing Party has been destroyed.  For the purposes hereof,
Proprietary Information does not include information which:

               (i) has been or may in the future be published or is now or may
               in the future be otherwise in the public domain through no fault
               of the receiving Party;

               (ii) prior to disclosure pursuant to this Contract is properly
               within the legitimate possession of the receiving Party;

               (iii) subsequent to disclosure pursuant to this Contract is
               lawfully received from a third party having rights in the
               information without restriction of the third party's right to
               disseminate the information and without notice of any restriction
               against its further disclosure;

               (iv) is independently developed by the receiving Party through
               parties who have not had, either directly or indirectly, access
               to or knowledge of such Proprietary Information;

               (v) is transmitted to the receiving Party after the disclosing
               Party has received written notice from the receiving Party that
               it does not desire to receive further Proprietary Information; or

               (vi) is obligated to be produced under order of a court of
               competent jurisdiction or other similar requirement of a
               Governmental Entity, so long as the Party required to disclose
               the information provides the other Party with prior notice of
               such order or requirement.

     (b)  Because damages may be difficult to ascertain, the Parties agree that
in the event of a breach or threatened breach of this Contract, without limiting
any other rights and remedies specified herein, an injunction may be sought
against the Party who has breached or threatened to breach this subsection
27.19.  Each Party represents and warrants that it has the right to disclose all
Proprietary Information which it has disclosed to the other Party pursuant to
this Contract, and each Party agrees to indemnify and hold harmless the other
from all claims by a third party related to the wrongful disclosure of such
third party's proprietary information.  Otherwise, neither Party makes any
representation or warranty, express or implied, with respect to any Proprietary
Information.

     27.20  Entirety of Contract; No Oral Change.  This Contract and the
            ------------------------------------
Exhibits and Schedules referenced herein constitute the entire contract between
the Parties with respect to the subject matter hereof, and supersede all
proposals, oral or written, all previous negotiations, and all other

            -------------------------------
with or merge into any other Person or convey, transfer or lease all or
substantially all of its assets to any Person, nor will any Person or group (as
such term is defined in the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) own or acquire fifty percent (50%) of the value of the Vendor's
equity where such Person or group did not own as of the Effective Date in excess
of ten percent (10%) of such equity (any such Person or group will be referred
to as the "Vendor's Succeeding Entity"), unless:

                         (i)   the Vendor's Succeeding Entity will agree to
               assume the obligations of the Vendor under this Contract; and

                         (ii)   the Owner will have approved the transaction,
               based solely on (i) the creditworthiness of the Vendor's
               Succeeding Entity, (ii) whether the Vendor's Succeeding Entity is
               a competitor of the Owner and (iii) whether in the Owner's
               reasonable judgment the Vendor's Succeeding Entity will be able
               to fulfill the obligations for present and future orders under
               this Contract.

     27.23  Change of Control of the Owner.  Except as otherwise permitted under
            ------------------------------
the documents relating to the financing of the build-out of the Nationwide
Network, the Owner will not consolidate with or merge into any other business

Exchange Act) own or acquire fifty percent (50%) of the value of the Owner's
limited partnership interests or general partnership interests where such Person
or group did not own as of the Effective Date in excess of ten percent (10%) of
either of such partnership interests (any such Person or group will be referred
to as the "Owner's Succeeding Entity"), unless:

     (a)  the Owner's Succeeding Entity will agree to assume the obligations of
the Owner under this Contract; and

     (b)  the Vendor will have approved the transaction, based solely on (i) the
creditworthiness of the Owner's Succeeding Entity and (ii) whether the Owner's
Succeeding Entity is a competitor of the Vendor.

     27.24  Relationship of the Parties.  Pursuant to subsection 27.9, nothing
            ---------------------------
in this Contract will be deemed to constitute either Party a partner, agent or
legal representative of the other Party, or to create any fiduciary relationship
between the Parties.  The Vendor is and will remain an independent contractor in
the performance of this Contract, maintaining complete control of its personnel,
workers, Subcontractors and operations required for performance of the Work.
This Contract will not be construed to create any relationship, contractual or
otherwise, between the Owner and any Subcontractor.

                                                                              88

     27.25  Discretion.  Notwithstanding anything contained herein to the
            ----------
contrary, to the extent that various provisions of this Contract call for an
exercise of discretion in making decisions or granting approvals or consents,
the Parties will be required to exercise such discretion, decision or approvals
in accordance with accepted PCS industry practices.

     27.26  Non-Recourse.  No past, present or future limited or general partner
            ------------
in or of the Owner, no parent or other affiliate of any company comprising the
Owner, and no officer, employee, servant, executive, director, agent or
authorized representative of any of them (each, an "Operative") will be liable
by virtue of the direct or indirect ownership interest of such Operative in the
Owner for payments due under this Contract or for the performance of any
obligation, or breach of any representation or warranty made by the Owner
hereunder.  The sole recourse of the Vendor for satisfaction of the obligations
of the Owner under this Contract will be against the Owner and the Owner's
assets and not against any Operative or any assets or property of any such
Operative.  In the event that a default occurs in connection with such
obligations, no action will be brought against any such Operative by virtue of
its direct or indirect ownership interest in the Owner.  The foregoing
provisions of this subsection 27.26 will not in any way limit or restrict any
right or remedy of the Vendor with respect to, and the Operatives will remain
fully liable for, any fraud perpetuated by such Operatives.

     27.27  Improvements, Inventions and Innovations.  All rights in any
            ----------------------------------------
improvements, inventions, and innovations made by the Owner will vest in the
Owner, and the Owner and its affiliates will have the right to exploit such
improvements, inventions, and innovations.  Except as may have been otherwise
agreed with respect to Custom Material under subsection 11.10.2, all rights in
any improvements, inventions and innovations made by the Vendor will vest in the
Vendor, and the Vendor and its affiliates will have the right to exploit such
improvements, inventions and innovations; provided, however, that the Owner and
                                          --------  -------
its affiliates will be granted a non-exclusive royalty-free license for use in
any future project in connection with or related to the System by the Owner (or
the parties that comprise the Owner or their respective affiliates) of any such
improvement, invention or innovation made by the Vendor (but not by any
Subcontractor) in the course and as a result of performing the Work and in which
the Vendor owns or possesses any proprietary interest.

     27.28  Attachments and Incorporations.  All Schedules and Exhibits attached
            ------------------------------
hereto, are hereby incorporated by reference herein and made a part of this
Contract with the same force and effect as though set forth in their entirety
herein.

     27.29  Conflicts.  In the event of any conflict or inconsistency among the
            ---------
provisions of this Contract and the documents attached hereto and incorporated
herein, such conflict or inconsistency will be resolved by giving precedence to
this Contract and thereafter to the Exhibits and Schedules.

     27.30  Counterparts.  This Contract may be executed by one or more of the

     Attached are the Owner's System Area (or MTA) coverage definition maps.


LEGEND

     The highways shown in green are only those highways with an average daily
traffic count of greater than 10,000 vehicles.  The darker green represents an
average daily traffic count of greater than 50,000 vehicles.

     The census tracts of the System Areas were combined and ranked by demand
density in erlangs (wireless talk time traffic) per square mile for year 10,
based on busy hour (peak daily demand hour) minutes of use estimates.  Those
tracts which fall within the top 70% of the population total a national level
are displayed in red.  Those tracts which fall within the next 10% of the total
population (70 to 80% at the national level) are displayed in pink.


INITIAL SYSTEM COVERAGE

     For contiguous Initial System coverage, the Contract's requirement is to
cover all of the red, pink and green areas within the blue "Arbitron Radio
Market" boundaries.  This represents 60% covered population at the national
level for the Initial System.

                                                          ----------
Notwithstanding the above, the Owner acknowledges and agrees that, unless the
Vendor otherwise notifies the Owner in writing to the contrary, the Software
contained in any Subscriber Unit manufactured by the Vendor prior to September
24, 1996 may contain "bugs" that may adversely impact the functionality,
performance and/or compliance of the Subscriber Unit with the Specifications
(such Software being hereinafter referred to as the "Beta Software").  With
respect to Subscriber Units forecasted pursuant to subsection 5.1(a) for
delivery on or before October 1, 1996 (the "Initial Subscriber Units"), the
Vendor will build and hold the Initial Subscriber Units in the Vendor's
inventory and will deliver such Initial Subscriber Units in accordance with the
provisions of this subsection 3.2(a).  Commencing on September 24, 1996 (and
assuming that the Owner will have placed Purchase Orders for such Products with
the Vendor in accordance with the lead times set forth in this Agreement), the
Vendor will deliver to the FOB point on a daily basis (or such other longer
time intervals ending before October 8, 1996 as the Vendor may request in
writing) those Initial Subscriber Units in which the Vendor has upgraded to the
Specifications the Beta Software.  On October 8, 1996, the Vendor will deliver
to the FOB point any then remaining Initial Subscriber Units still in the
Vendor's inventory as of such date (and the Owner will have placed Purchase
Orders for such Products with the Vendor in accordance with the lead times set
forth in this Agreement).  Prior to

                                      -11-
<PAGE>

their respective delivery to the FOB point pursuant to the prior two sentences,
the Vendor will upgrade to the Specifications the Beta Software in the subject
Initial Subscriber Units.  For each of the Initial Subscriber Units so held in
the Vendor's inventory and upgraded, the Owner will pay to the Vendor a fee of
[   ] Initial Subscriber Unit to be upgraded to the Specifications, such
fee due and payable on the date the invoice for such Products is due and
payable.  The Owner may request in writing that up to [   ] of the Initial
Subscriber Units be delivered (with their accompanying Material Accessories)
prior to the dates specified above. Upon such written request, the Vendor will
use its reasonable commercial efforts to comply with the dates and quantities
specified by the Owner in such request forsuch Initial Subscriber Units to be
delivered prior to September 24, 1996; provided that between September 24, 1996
                                       -------- ----
and October 8, 1996, the Owner may request the delivery of any remaining Initial
Subscriber Units (subject to the [   ] limitation set forth above) that have not
been upgraded and were not earlier delivered prior to September 24, 1996. During
the period from September 24, 1996 to October 8, 1996 the Owner may request and
the Vendor will deliver as many upgraded Specification compliant Subscriber
Units as it has so upgraded and otherwise made available pursuant to and in
accordance with the forecasting and ordering requirements set forth in this
Agreement. With respect to any such Initial Subscriber Unit delivered prior to
the dates specified above, (i) acceptance of such Initial Subscriber Units with
the Beta Software will be deemed to have occurred upon delivery, (ii) the Vendor
makes no warranty with respect to the Beta Software (such Beta Software being
delivered on an "AS IS" basis), nor does the Vendor make any warranty with
respect to compliance of such Initial Subscriber Units with the Specifications
as a result of the fact that such Initial Subscriber Units contain Beta
Software; provided that any such Initial Subscriber Unit will be fully
          -------- ----
compliant with all other applicable Specifications and the Vendor's warranties
pursuant to subsections 3.7 and 3.8 shall remain in full force and effect except
with respect to the effects of such Beta Software, and (iii) the Vendor shall
have no obligation to upgrade the Beta Software in such delivered Initial
Subscriber Units, but the Vendor agrees to cooperate, to the extent set forth in
the next sentence, with the Owner to assist the Owner to upgrade such Beta
Software in the field. In the event that there are Initial Subscriber Units
containing Beta Software delivered by the Vendor, the Vendor will supply to the
Owner, at no charge to the Owner, the computer disks containing the software
upgrades and reasonable amounts of training and assistance to permit the Owner
to implement a field upgrade of such Beta Software. The provisions of subsection
5.2(c) and subsection 5.2(d) will not apply to Initial Subscriber Units unless
and only to the extent that the Owner postpones delivery of any Initial
Subscriber Units to a date after October 8, 1996 (in which event, for purposes
of applying the provisions of subsection 5.2(c) and subsection 5.2(d), the
initial shipment date for such Initial Subscriber Units will be deemed to be
October 8, 1996). For the purposes hereof, a "bug" or "bugs" means a Software
imperfection, but in any event such Initial Subscriber Units with Beta Software
will be able to at least perform the following basic functions: which are
"power-up," "power-down," placing calls, receiving calls, perform self-check on

      (b)  Pursuant to and in accordance with the terms of this Agreement,
during the Initial Term of this Agreement the Owner will purchase from the
Vendor not less than [   ] Subscriber Units (the "Total Minimum Commitment").
During the first six (6) months from the Commencement Date (such first six month
period and each succeeding twelve (12) month period during the Term an "Annual
Supply Period") the Owner will only be required to purchase from the Vendor
[   ] Subscriber Units (the "First Annual Minimum Commitment"). During the
second Annual Supply Period the Owner will only be required to purchase from the
Vendor [   ] Subscriber Units (the "Second Annual Minimum Commitment"). During
the third Annual Supply Period the Owner will only be required to purchase from
the Vendor [   ] Subscriber Units (the "Third Annual Minimum Commitment"; each
of the First Annual Minimum Commitment, Second Annual Minimum Commitment, and
Third Annual Minimum Commitment, an "Annual Minimum Commitment").
Notwithstanding anything stated in this subsection 3.2(b) to the contrary, in
any given Annual Supply Period the Owner will only have to purchase [   ] of the
respective amounts set forth in the second, third and fourth sentences of this
subsection 3.2(b), provided that at any time prior to the termination of the
                   -------- ----
Initial Term (unless earlier terminated in accordance with Section 10) the Owner
will have fulfilled its Total Minimum Commitment pursuant to and in accordance
with the terms of this Agreement. Pursuant to and in accordance with the
immediately preceding sentence, any amounts (up to [   ]) not purchased, or
otherwise subject to firm Purchase Orders in accordance with this Agreement, by
the Owner in any given Annual Supply Period will increase the Annual Minimum
Commitment in the next succeeding Annual Supply Period (without any penalty or
Shortfall payment by the Owner to the Vendor); provided that for the third
                                               -------- ----
Annual Supply Period any such amounts [   ] will be carried over and into the
remaining period within the Initial Term (the "Stub Period") and must be
purchased by the Owner in accordance with the terms of this Agreement during the
Stub Period. Prior to the end of the first Annual Supply Period, the second
Annual Supply Period and the third Annual Supply Period, the Owner will give the
Vendor prior written notice of any election by the Owner to exercise the Owner's
rights under the preceding sentence to purchase less than [   ] of the amount of
the First Annual Minimum Commitment, the Second Annual Minimum Commitment and
the Third Annual Minimum Commitment, as applicable, in the respective first
Annual Supply Period, second Annual Supply Period and the third Annual Supply
Period, as the case may be.

      (c)  In the event that the Owner elects, in its sole discretion, not to
place Purchase Orders for delivery of Subscriber Units in accordance with the
terms of this Agreement in the amounts as set forth in subsection 3.2(b) above
(the difference between each of the Annual Minimum Commitments and the amount
actually ordered for delivery during each of the relevant Annual Supply Periods
set forth in subsection 3.2(b) or otherwise during the Stub Period by the Owner
herein referred to as the "Shortfall"), then the amount of the relevant Annual
Minimum Commitment for such period (or the residual amount to be purchased in
the Stub Period, as applicable) will be reduced (by an amount equal to the
amount of the Shortfall for such Annual Supply

                                      -13-
<PAGE>

Period or the Stub Period, as the case may be) by paying to the Vendor the
following amounts per Subscriber Unit which are in any such Shortfall, as full
compensation to the Vendor for such a reduction in the applicable Annual
Minimum Commitments:



                                                Charge per Subscriber
Amount of Shortfall                             Unit in the Shortfall
- - - -------------------                             ---------------------

Shortfall greater than or equal to [   ]        [   ] per Subscriber Unit in
of the applicable Annual Minimum                Shortfall
Commitment

Shortfall greater than or equal to [   ]        [   ] per Subscriber Unit in
and less than [   ] of the applicable           Shortfall
Annual Minimum Commitment

Shortfall greater than or equal to [   ]        [   ] per Subscriber Unit in
and less than [   ] of the applicable           Shortfall
Annual Minimum Commitment

Shortfall less than [   ] of the applicable     [   ] per Subscriber
Annual Minimum Commitment                       Unit in Shortfall

      To the extent there is a Shortfall in any Annual Supply Period or the
Stub Period, as the case may be, the Vendor may invoice the Owner for any
amounts owed by the Owner to the Vendor pursuant to this subsection 3.2(c) no
earlier than 5:00 p.m. on the last Business Day of such period and no later
than ninety (90) days from the last Business Day of such period and the Owner
will have sixty (60) days to pay any such invoice to the extent the amount of
any such invoice is not in good faith dispute between the Parties pursuant to
subsection 11.8.  To the extent the Owner is required to pay the Vendor amounts
as set forth in this subsection 3.2(c) for any Shortfall during any Annual
Supply Period, or during the Stub Period, as the case may be, any such amounts
once paid by the Owner will be full compensation to the Vendor for such
reduction in the Annual Minimum Commitments and the Owner will have no further
liability or obligation of any kind to the Vendor for any such reductions in
the Annual Minimum Commitments and any such payment will be the Vendor's sole
remedy (at law or in equity) for any such reductions in the Annual Minimum
Commitments.  Nothing set forth in subsections 3.2(b) or 3.2(c) will be
construed or interpreted as relieving the Owner of purchasing those amounts of
Products projected by the Owner in the first five (5) months of a Forecast
which are subject to a firm Purchase Order in accordance with subsection 5.1.
For the purpose of subsections 3.2(b) and 3.2(c), any Purchase Order or Excess
Purchase Order postponed by the Owner pursuant to subsection 5.2(c) which, as a
result of such postponement, would cause the Products subject to such Purchase
Order or Excess Purchase Order not to be purchased in the Annual Supply Period
(the "Originally Scheduled Supply Period") in which such Products otherwise
were to be purchased (but for such postponement), will not be considered to be
Purchase Orders for Products ordered for delivery in the Originally Scheduled
Supply Period and such Products may be considered as part of any such Shortfall
during the Originally Scheduled Supply Period.

      3.3  Most Favored Customer Status.  (a)  With respect to all Products
           ----------------------------
(including any New Products ordered by the Owner pursuant to the terms of this
Agreement), the Owner will be deemed the most important and favored Customer of
the Vendor and will always throughout the [   ].  Notwithstanding the
above, the Vendor will not be obligated to provide such priority to Owner if
providing such priority either (i) would cause the Vendor, QUALCOMM or Sony
(including their respective affiliates) to breach any of their then-existing
contracts and/or any Applicable Law, or (ii) if the Owner elects to exercise
any of its remedies, as specified in subsection 4.2.  At any time during the
Term, the Owner will receive Products (including any New Products ordered by
the Owner pursuant to the terms of this Agreement) at prices (prior to taking
into account price increases due to customization specific to the Owner;
[   ]. For the purposes of subsection 3.3 only, "Customer" will not include any
(i) OEM Customer or (ii) any other Customer who is only receiving Products from
the Vendor (or its affiliates) as a piece of a larger telecommunications,
engineering and/or design contract (other than with respect to Products sold
under a contract(s) with a third party to the extent that (x) the price
differential between the Product(s) sold under such third party contract (taking
into account corresponding time periods) multiplied by the number of units of
                                         ---------- --
Product(s) to be sold under such third party contract (at a lower price), is (y)
greater than [ ] of the total contract value of such third party contract), the
primary purpose of which is not the sale or supply of Subscriber Units.

      (b)  On an annual basis throughout the Term of this Agreement commencing
on the Effective Date, each of the Vendor, Sony and QUALCOMM will be required
to audit their pricing of all similar products provided to all of their
customers selling or using or intending to sell or use the Products in the
Territory in the preceding calendar year and certify to the Owner in a
certificate (or in separate certificates) executed by a duly authorized officer
of each such entity (the "MFC Certificate") that the Owner has in fact received
the prices and availability of Products in accordance with the terms of

                                      -15-
<PAGE>

clause (a) of this subsection 3.3.  The annual MFC Certificate delivered to the
Owner in accordance with this subsection 3.3(b) will be subject to
verification, at the election of the Owner, by any public accounting firm
reasonably acceptable to the Owner and listed on Schedule 1 (the "Independent
Public Accountant") and at the sole cost and expense of the Party whose
position is not supported by the report of the Independent Public Accountant
or, if contested, the report of the Independent Auditor.  The Independent
Public Accountant will in no event disclose to the Owner or any other third
party the details of any contract or amendment between the Vendor and any
Customer (or between QUALCOMM and any of QUALCOMM's customers or between Sony
and any of Sony's customers or between any affiliate and such affiliate's
customers) other than details as necessary to summarize terms including, but
not limited to, pricing relevant to determinations under subsections 3.3(a) and
(b).

      (c)  To the extent that it is determined pursuant to subsection 3.3(b)
that the provisions of subsection 3.3(a) have not been complied with, the Owner
will have thirty (30) Business Days from receipt of the MFC Certificate (as
verified by the Independent Public Accountant, if the MFC Certificate(s) was so
subject to verification) to provide the Vendor with a written claim for Product
pricing rebates (as measured from the date any Product is delivered at any such
lower prices in violation of this subsection 3.3) on future purchases under
this Agreement based upon (i) the Independent Public Accountant's calculation
of the price differentials between the Vendor's prices for Products (including
any New Products) under this Agreement and any lower prices charged by the
Vendor, Sony or QUALCOMM, as the case may be, to any other Customer (including
customers of either QUALCOMM or Sony (including their respective affiliates)
who intend to use or resell, or who actually use or resell, such Products
within the Territory) in violation of clause (a) of this subsection 3.3.  To
the extent that the Vendor, Sony or QUALCOMM, as the case may be, disagrees
with any such claim for such pricing rebates made by the Owner pursuant to this
subsection 3.3(c), the Vendor will have the right within ten (10) Business Days
of receiving the Owner's written rebate claim to submit such claim (including,
but not limited to, the Independent Public Accountant's report on which it as
based) and the Vendor's written response thereto to an Independent Auditor
(other than the Independent Public Accountant) who will have the authority to
determine whether, based on the information provided by the Owner and the
Vendor, the provisions of subsection 3.3(a) have been complied with.  As part
of any such submission to the Independent Auditor, either Party may dispute the
validity or accuracy of the Independent Public Accountant's report.  If the
Independent Auditor finds that the Owner's pricing rebate claim is incorrect
but that the provisions of subsection 3.3(a) have been violated, then the
Independent Auditor will have the right to adjust any such claim as appropriate
under such circumstances.  The Independent Auditor's determination must be made
and delivered to both the Vendor and the Owner within ten (10) Business Days of
receiving the request from the Vendor.  Such determination once made by the
Independent Auditor will be final and binding on the Parties and will not be
subject to further modification.  The costs and expenses of the Independent
Auditor will be borne by the Party whose position is not supported by the
Independent Auditor or otherwise equitably under the circumstances.

      3.4  Payment Terms, Taxes and Co-op Marketing Fund.  (a)  Pursuant to
           ---------------------------------------------
and in accordance with the terms of this Agreement, the Vendor will invoice the
Owner for Products purchased upon delivery of such Products to the FOB point,
and the Owner will pay all such invoices within [   ] days after the
invoice date unless the Owner disputes (in accordance with subsection 11.8) in
good faith either the Vendor's entitlement to, or the amount of, any such
invoiced amount.  The Owner agrees to pay to the Vendor a late charge for
amounts actually due and not paid when due in accordance with the terms of this
Agreement (a "Late Amount") equal to the lesser of [   ] per month,
pro-rata, of the Late Amount, or the maximum amount permitted by Applicable
Law; provided that any such late payment penalties will not accrue
              ----
until amounts owed by the Owner to the Vendor are actually late and outstanding
and will stop accruing immediately upon the Owner's payment of such Late Amount
plus any such accrued late payment penalties.  All amounts stated herein and/or
otherwise required to be paid under or pursuant to this Agreement are stated
in, and will be paid in, U.S. Dollars.  In the event that, at any given time,
there are undisputed amounts, in aggregate, of [   ] or more, which the Owner
has failed to pay when due in accordance with the terms of this Agreement, then
the Vendor, upon five Business Days prior written notice to the Owner, shall be
entitled to, without any penalty or payment obligations, suspend shipping
Products.

      (b)  The amounts to be paid by the Owner under this Agreement do not
include any state, provincial or local sales and use taxes, however designated,
which may be levied or assessed on the Products to be sold hereunder.  With
respect to such taxes, the Owner will either furnish the Vendor with an
appropriate exemption certificate applicable thereto or pay to the Vendor, upon
presentation of invoices therefor, such amounts thereof as the Vendor may by
law be required to collect or pay; provided, however, that the Vendor
                                   --------  -------
will use its reasonable efforts to minimize the amount of any such taxes.  The
Owner has no obligation to the Vendor with respect to other taxes, including,
but not limited to, those relating to franchise, net or gross income or
revenue, license, occupation, other real or personal property, and fees
relating to importation or exportation of the Products to the FOB point.

      (c)   Throughout the Term the Vendor will contribute cash amounts equal
to [   ] of the invoiced FOB point price of any Subscriber Units (and their
included accompanying Material Accessories) so invoiced by the Vendor to the
Owner for such Products purchased and paid for by the Owner pursuant to the
terms of this Agreement to a separate fund owned by the Owner and designated in
writing to the Vendor from time to time by the Owner (the "Co-op Marketing
Fund"). Any and all amounts in the Co-op Marketing Fund may be used by the Owner
in its sole and absolute discretion for any purpose in connection with the
marketing and/or advancement of the Nationwide Network or any part thereof,
subject only to the terms of subsection 3.17(b) and Section 8. In accordance
with the terms of this subsection 3.4(c), the Vendor must make any such
contribution to the Co-op Marketing Fund within ten (10) Business Days of
receipt by the Vendor of full payment by the Owner of amounts due under any such
invoice for Subscriber Units (and their included Material Accessories). The
amount of any such contribution to be made by the Vendor pursuant

                                      -17-
<PAGE>

to this subsection 3.4(c) will be calculated based upon [   ] of the invoiced
FOB point price for Subscriber Units (and their included Material Accessories)
invoiced by the Vendor to the Owner. The failure of the Vendor to make the
contributions in cash to the Owner's Co-op Marketing Fund in accordance with and
subject to the terms of this subsection 3.4(c) will entitle the Owner to
withhold any such amounts from any future Vendor invoices (until such time as
the Vendor does make any such required contributions).

      3.5  Delivery.  (a)  All deliveries of Products will be made to the
           --------
FOB point.  The Owner will specify the desired method of shipping.  Unless
otherwise agreed in writing, the Owner will pay for all shipping, freight,
insurance and other similar charges incurred in connection with such
deliveries.  In the absence of written shipping instructions from the Owner,
the Vendor will select the carrier and insurance company at the Owner's
expense, taking into account the charges levied by the carriers and insurance
companies under consideration, and will ship Products utilizing ground
transportation; provided that, in the absence of prior shipping
                -------- ----
instructions, the Vendor will use reasonable efforts to contact the Owner to
request such shipping instructions prior to making any such selections.

      (b)  The Owner will inspect and either accept or reject all Products in
whole or in part within ten (10) Business Days after the date of receipt at the
delivery location applicable to such Products pursuant to the terms of this
Agreement.  If the Owner fails to reject any Product delivered within such
period, the Owner shall be deemed to have accepted such Product; provided,
                                                                 --------
however, that any such acceptance will in no event limit, modify, waive or
- - - -------
otherwise restrict the Owner's rights under the terms, including without
limitation the warranty provisions, of this Agreement.

      (c)  The Owner may request that the Vendor provide more extensive
logistical and distribution capabilities to the Owner, which capabilities the
Vendor will use its reasonable commercial efforts to provide.  If the Vendor
agrees to provide such services, there may be, depending on the level and scope
of such services, additional charges to the Owner on a per Product basis.  Any
such charges will be mutually agreed upon by the Parties during negotiations
between the Parties on the provision of any such additional logistical and
distribution services beyond those outlined in this subsection 3.5;
provided that, in determining any such charges, the Owner will be
- - - -------- ----
deemed the Vendor's most important and favored Customer and will receive such
services at prices, on payment terms and subject to all other contract terms on
terms no less favorable to the Owner than those offered or available to any
other Customer subject to and in accordance with the terms of subsection 3.3.

      3.6  Pricing.  (a)  The Owner will purchase Products from the Vendor
           -------
in accordance with the Product pricing set forth on Appendix 1.  The price for
Products will be the price in effect on the date of the applicable Purchase
Order.  Notwithstanding anything to the contrary contained in subsection 3.2(b)
or subsection 5.2(c), to the extent the Owner orders or is required to order
Subscriber Units during 1996, the Owner will be required to pay the 1996 price
(as set forth in Appendix 1) for

                                      -18-
<PAGE>

such Subscriber Units, even if and notwithstanding the fact that the Owner will
have moved, or delayed the delivery (pursuant to subsection 3.2(b) or
subsection 5.2(c)) of any such first Annual Supply Period Subscriber Units into
a succeeding Annual Supply Period or the Stub Period, as the case may be;
provided, however, that nothing contained in this sentence will in any
- - - --------  -------
way limit or modify the Owner's right to reduce its First Annual Minimum
Commitment pursuant to the shortfall mechanisms in subsection 3.2(c);
provided further, however, in the event the Owner so reduces its
- - - -------- -------  -------
First Annual Minimum Commitment but does purchase Subscriber Units subsequent
to December 31, 1996, then the Owner will be required to pay, for each
Subscriber Unit until such time as the Owner has purchased, in aggregate, [   ]
Subscriber Units, an amount equal to (i) the 1996 price (as set forth in
Appendix 1) for such Subscriber Units, less (ii) the amount paid by the Owner to
the Vendor (calculated on a per Subscriber Unit basis) pursuant to subsection
3.2(c) as a result of there being a Shortfall in the First Annual Supply Period.
Pursuant to the terms of this Agreement the Vendor may, upon not less than sixty
(60) days prior written notice to the Owner, increase its pricing for any of its
Products covered by the terms of this Agreement as set forth in Appendix 1 only
once in any given Annual Supply Period, in accordance with the most favored
customer provisions set forth herein; provided that any such price increase will
                                      -------- ----
in no event be in excess of [   ] above the previously established price as set
forth in Appendix 1 for any such Product; and provided further, that nothing in
                                              -------- -------
this subsection 3.6 will limit or otherwise pertain to a price increase
implemented pursuant to a Change Order pursuant to and in accordance with
subsection 3.23. In the event of any such price increase the Owner will have the
right, but not the obligation, by written notice to the Vendor, to reduce the
then remaining unpurchased portion of the applicable Annual Minimum Commitment
by the same percentage [   ] as such price increase in such Annual Supply
Period. For example, if the Vendor pursuant to the terms of this subsection
3.6(a) chose to increase its prices during the First Annual Supply Period by
[   ], then the Owner would have the corresponding right to decrease the then
remaining unpurchased portion of the First Annual Minimum Commitment by [   ].
Initial pricing for new Products not otherwise covered by Appendix 1 or the
terms of this Agreement will be established by mutual good faith agreement
between the Parties, such agreement to be reached no less than ninety (90) days
prior to the commercial availability of any such new Products to any Customer.
All such pricing for such new Products will be determined in accordance with the
terms of this Agreement, including, but not limited to, the most favored
customer provisions set forth herein.

      (b) In the event that the Vendor reduces the price (other than the
automatic annual price reductions set forth in Appendix 1 or any price reduction
due to a violation of subsection 3.3) of any Product, the Vendor will credit the
Owner's accounts payable with an amount equal to the difference between the
reduced price (less the applicable [   ] Co-op Marketing Fund contribution
referenced in subsection 3.4(c)) and the price (less the applicable [   ] Co-op
Marketing Fund contribution referenced in subsection 3.4(c)) in effect
immediately prior to such reduction multiplied by the number of units of such
Product which were shipped to the Owner during the thirty (30) days immediately
prior to such price reduction and which remain in the

                                      -19-
<PAGE>

Owner's inventory at such time (the "Affected Products").  Within thirty (30)
days of such price reduction taking effect, the Vendor will notify the Owner of
such price reduction.  If the Vendor fails to provide the Owner with such a
credit within such thirty (30) day period after notification by the Owner of
such quantities remaining in the Owner's inventory, the Owner will be entitled
to offset the amount of such credit (calculated in accordance with the
immediately preceding sentence) first against the amounts owed for any of the
Affected Products, and second against any other amounts due to the Vendor by
the Owner pursuant to this Agreement.  The Vendor will have the right, but not
the obligation, to have an Independent Auditor audit the Owner's calculation of
the quantity of Products that remain in the Owner's inventory immediately prior
to such price reduction, provided that the Party whose position is not
                         -------- ----
supported by the Independent Auditor will be responsible for the costs and
expenses of the Independent Auditor designated pursuant to this subsection
3.6(b).

      (c)  The Owner will receive from the Vendor purchasing credits to be
applied as a reduction in the purchase price of Subscriber Units (with
accompanying Material Accessories) purchased by the Owner in 1998 as follows:
for each Subscriber Unit (with accompanying Material Accessories) purchased by
the Owner in 1997, the Owner will receive from the Vendor [   ] credit (the
"Purchasing Credits").  The Purchasing Credits will be applied by the Vendor
against purchases by the Owner of Subscriber Units in 1998 as a
reduction in the purchase price of such Subscriber Units; provided,
                                                          --------
however the amount of the Purchasing Credits to be applied to reduce the
- - - -------
purchase price of any individual Subscriber Unit (with accompanying Material
Accessories) purchased in 1998 will be [   ] or such lesser then remaining
unused amount (if the amount of remaining unused Purchasing Credits is then
less than [   ].

      3.7  Warranty to the Owner.  (a)  The Vendor warrants to the Owner
           ---------------------
that each Product will be, during the applicable Warranty Period, free from
Defects or Deficiencies in material and workmanship.

      (b)  In the event of any breach of the warranty set forth in subsection
3.7(a) during the applicable Warranty Period, the Vendor will, in accordance
with the terms of this subsection 3.7, promptly repair or replace (in
accordance with subsection 3.9) the defective or nonconforming Product or
otherwise cure any Defects and Deficiencies so that the defective or
nonconforming Product will perform in accordance with the Specifications.  If
the Vendor fails to promptly repair, replace and/or cure such defect or
nonconformance, the Vendor will promptly refund any monies paid by the Owner
for such Defective Product, less any amounts contributed by the Vendor to the
Co-op Marketing Fund relating to such defective Product (such refund to be made
no later than the notice to the Owner that it will not repair and replace).
The remedies set forth in this subsection 3.7(b) will be the sole and exclusive
remedies in the event of a breach by the Vendor of its obligation under this
subsection 3.7.

      (c)  No warranty will extend to any Product which has been subjected to
misuse, neglect or improper storage or installation by any Person other than
the Vendor, its

                                      -20-
<PAGE>

agents, employees, subsidiaries and/or affiliates or which has been used with
accessories other than Accessories provided by the Vendor (or expressly
authorized in writing by the Vendor for use with the subject Product) or any
Product which has been opened, repaired, modified or altered by anyone other
than the Vendor or a Vendor authorized repair facility.

      (d)  The Owner hereby acknowledges and agrees that it has not relied on
any representations or warranties other than those expressly set forth in this
Agreement.  During the applicable Warranty Period (in no event less than the
Term), Vendor will provide, at Vendor's sole expense, to the Owner telephonic
technical support, including a hotline staffed from 7:00 a.m to 10:00 p.m.
Eastern time seven (7) days a week.

      3.8  Consumer Warranty.  (a)  In addition to the warranty provided in
           -----------------
subsection 3.7, the Vendor will provide a warranty ("Consumer Warranty") to
Purchasers of Sony Branded Products, on the terms and conditions set forth on
APPENDIX 3, and to Purchasers of all other Products, on the terms and
- - - ----------
conditions set forth on APPENDIX 2.  At the election of the Owner and
                        ----------
upon prior written notice to the Vendor, the Consumer Warranty for Subscriber
Units not yet delivered to the FOB point can be extended from twelve (12)
months to twenty four (24) months from the date of sale and the forms of the
Consumer Warranty set forth on Appendices 2 and 3 (which shall accompany such
Subscriber Units, as applicable) shall be appropriately modified to implement
the warranty extension for such Subscriber Units.  The amount of prior written
notice which the Owner must give to the Vendor to implement such a warranty
extension shall be mutually agreed upon (in any event not in excess of ninety
(90) days) in each instance, taking into account such factors as printing and
packaging lead times, which may vary depending on the number of phones to be
subject to such warranty extension, and any other relevant factor.  The Parties
agree that the Consumer Warranty is made solely by the Vendor and that the
Owner makes no warranties with respect to the Products pursuant to this
Agreement.  In the event any such Purchaser inadvertently or otherwise forwards
Products subject to the Consumer Warranty to the Owner, the Owner will have the
right to forward such Products to the Vendor and the Vendor will perform its
obligations under the Consumer Warranty as if such Purchaser forwarded such
Products directly to the Vendor.

      (b)  During the Consumer Warranty period the Vendor agrees to allow a
Purchaser to return a Subscriber Unit (with the original accompanying Material
Accessories) to the Owner or to the locations described in Schedule 4 (or, with
respect to Sony Branded Product, to any authorized dealer or service facility,
as contemplated by APPENDIX 3) for a replacement thereof by the Vendor
                   ----------
in the event that such Subscriber Unit or any such accompanying Material
Accessory suffers from a Defect or Deficiency within ten (10) days after the
purchase of such Subscriber Unit (with such accompanying Material Accessories).
Upon the Owner's receipt of a Defective Product (and prescribed accompanying
Products, if required) from a Purchaser the Owner will have the right to
deliver any such Defective Product (and prescribed accompanying Products, if
required) to the Vendor and the Vendor will within ten (10) days of its receipt
of such Defective Product (and prescribed accompanying Products, if required)
from the Owner replace

                                      -21-
<PAGE>

such Defective Product by sending a replacement Product directly to the Owner
or its designated agents, or as otherwise mutually agreed by the Parties.

      3.9  Repair and Replacement Services.  (a)  If the Owner claims a
           -------------------------------
breach of warranty under subsection 3.7, it must notify the Vendor of the
claimed breach within a reasonable time (in any event during the applicable
Warranty Period) after its determination that a breach has in fact occurred.
The Owner will allow the Vendor to inspect the Products, at the Owner's
location designated for such purpose, or, upon the Vendor's issuance of a
return authorization number and at the Vendor's sole expense, the Owner will
return via ground transportation such Products to any of the Vendor's
designated repair facilities located in the United States and listed on
Schedule 4.  Notwithstanding anything to the contrary in this subsection
3.9(a), the Owner agrees to pay to the Vendor the lesser of (i) the Vendor's
then current standard cost to refurbish and transport the NTF Product or (ii)
thirty daollars ($30) per NTF Product for each NTF Product actually replaced
with a refurbished or new Product by the Vendor, provided that the Owner will
have the right, but
                              -------- ----
not the obligation, to designate an Independent Auditor to verify the Vendor's
calculation of the quantity of and the Vendor's standard cost to refurbish and
transport any such NTF Products received by the Vendor pursuant to this
subsection 3.9; provided further that the costs and expenses of the Independent
                -------- -------
Auditor will be borne by the Party whose position is not supported by the
Independent Auditor or otherwise equitably under the circumstances.

      (b)  Upon request by the Owner for a return authorization, pursuant to
subsection 3.7 or 3.8, whether for replacement or for repair of a Product, the
Vendor agrees that, within thirty (30) days of such Owner request, it will
either issue such return authorization number or provide the Owner in writing
with reasons for refusing to issue such return authorization number.  In the
event that the Vendor fails to provide the return authorization number, or
provide written reasons for refusing to do so, the Owner will be permitted to
offset the value of any amount paid for the Product against any other amounts
owed by the Owner to the Vendor pursuant to this Agreement; provided
                                                            --------
that in the event of any such offset the Vendor may request the return of
- - - ----
the subject Product and, in the event of such request, the Owner will return
such Product.

      (c)  The Vendor will repair Products as soon as practicable after receipt
of the Defective Product giving rise to the warranty claim and will maintain a
maximum ten (10) day turn-around time to either repair or replace Products.
Turn-around time is the time between receipt by the Vendor of the Defective
Product and shipment for return by the Vendor of the repaired or replacement
Product.  When repairing or replacing any Defective Product, the Vendor will
maintain the quality of the Product and will not substitute any component
thereof with a component of lesser quality or with a component that has a
lesser performance standard or capability.  Subject to the immediately
preceding sentence, the Vendor will be entitled to repair or replace defective
Products using refurbished components and refurbished Products.

      3.10  Catastrophic Defects  (a)  Throughout the applicable Warranty
            --------------------
Period for each Product, as applicable to each Product, in the event that (i) in
excess of [   ] of the Products in any class, category or type of Products (a
"Product Class") shipped to the Owner in the initial [ ] period following the
first commercial sale by the Vendor to the Owner of such Product (a "First Sale
Date") (provided that in any event at least [ ] separate Products) are found to
        -------- ----
be Defective within any consecutive [ ] month period, (ii) in excess of [ ] of
the Products in any Product Class shipped to the Owner in the second [ ] month
period following the First Sale Date (provided that in any event at least
                                      -------- ----
[ ] separate Products) are found to be Defective within any consecutive [ ]
month period or (iii) in excess of [ ] of the Products in any Product Class
shipped to the Owner after the [ ] month period following the First Sale Date
(provided that in any event at least [ ] separate Products) are found to be
 -------- ----
Defective within any consecutive six (6) month period (any such defect described
in clauses (i), (ii) or (iii) above hereinafter referred to as a "Catastrophic
Defect") the Owner will notify the Vendor thereof. Upon receipt of such
notification, the Vendor will have ninety (90) days in which to determine the
cause of and to remedy such Defect (the "Catastrophic Defect Cure Period"). Upon
such remediation, the Vendor will promptly repair or replace any and all
Products that were subject to the same or similar condition(s) causing such
Catastrophic Defect (in the Owner's inventory and any such Products sold by the
Owner to Purchasers) with repaired or otherwise replaced Products at the
Vendor's sole expense (including, without limitation, all freight and duty
payments applicable thereto). In order to accurately determine that any
Catastrophic Defect has in fact been cured by the Vendor in accordance with the
terms of this subsection 3.10, the Owner will not exercise any of its remedies
under this subsection 3.10 against the Vendor until and unless the Defect
percentages for any such class, category or type of Products subject to such a
Catastrophic Defect, as measured during a ninety (90) day period starting on the
date the Vendor commences any such remediation, has failed to fall below the
applicable threshold percentages set forth in clauses (i), (ii) or (iii) above.
      (b)  In the event that such Catastrophic Defect is not remedied within
the Catastrophic Defect Cure Period in accordance with this subsection 3.10,
the Owner will have the right, but not the obligation, to terminate this
Agreement and to resell to the Vendor for cash payment any and all Products
which are then in the Owner's inventory and which are subject to such
Catastrophic Defect or which are subject to the same or similar condition(s)
causing such Catastrophic Defect at the price paid (less any applicable amounts
contributed by the Vendor to the Co-op Marketing Fund for such Product and less
any Product Depreciation) to the Vendor by the Owner, without charge
(including, without limitation, any restock charge) or penalty; provided
                                                                --------
that if the Vendor is diligently pursuing a cure, prior to any such
- - - ----
termination the Owner will allow the Vendor an additional fifty (50) days to
remedy such Catastrophic Defect (provided further that any such resale
                                 -------- -------
will be implemented at the end of the initial ninety (90) day cure period for
such Catastrophic Defect).  Regardless of whether the Owner exercises the
rights set forth in the immediately preceding sentence, in the event that such
Catastrophic Defect is not remedied, the Vendor agrees to reimburse the Owner
for any

                                      -23-
<PAGE>

and all reasonable direct out of pocket expenses and costs in excess of any
expenses and costs the Owner would have otherwise incurred hereunder in
reasonably replacing (using replacement Products with the most comparable
features and functionality available at such time) the Owner's or any
Purchasers' Products as a result of such Catastrophic Defect and to repurchase
from the Owner any Vendor Products repurchased or otherwise recalled by the
Owner due to the Vendor's failure to remedy any such Catastrophic Defect.

      (c)  In the event the Vendor has failed to perform any of its warranty
obligations under the terms of this Agreement and if the Vendor purchases or
subcontracts for the manufacture of any part of any Product to be provided
hereunder from a third party, the warranties given to the Vendor by such third
party will inure, to the extent applicable, permitted by such warranties and
permitted by Applicable Law, to the benefit of the Owner, and the Owner will
have the right, to the extent permitted by such warranties and Applicable Law,
in its sole discretion, to enforce such warranties directly against such third
party.  The remedies set forth in subsections 3.10(b) and (c) will be the sole
and exclusive remedies in the event of a breach by the Vendor of its obligation
under subsection 3.10(a) above.

      (d) Notwithstanding that the applicable Warranty Period in respect
thereof may have expired, the Vendor will provide repair and maintenance (but
not replacement) services as set forth in subsection 3.9 with respect to any
Product purchased under this Agreement for a period of five (5) years following
the purchase of such Product at its standard commercial prices which will be
reasonable,  unless (i) such Product has been subjected by a Person other than
the Vendor (or any of its subcontractors or suppliers) to misuse, neglect or
improper storage or installation or (ii) is in such deteriorated or damaged
condition that it cannot reasonably be repaired.  In the event that a Product
is not repairable, the Vendor will return such Product to the Person who
returned such Product (at such Person's cost), with a statement certifying the
reasons why such Product cannot be repaired.

      3.11  New Generation of Products.  The Vendor may, from time to time
            --------------------------
during the Term of this Agreement, modify, update or enhance existing or
produce new generations, or updated, modified or enhanced versions, of Products
sold hereunder ("New Products").  In the event that the Vendor makes such New
Products generally available to any of its other Customers, the Vendor will
offer to sell such New Products to the Owner on terms and conditions pursuant
to and in accordance with subsection 3.3.  Notwithstanding anything stated
herein to the contrary, no Product subject to a modification which in no way
affects the form, fit or functionality of the Product will be deemed a New
Product and any such Product will remain a Previously Existing Product.

      3.12  Right to Cease Supply of Obsolete Products.  If the Vendor
            ------------------------------------------
begins selling and making generally available New Products or products to
replace or as a substitute for previously existing Products ("Previously
Existing Products"), the Vendor may, with the Owner's prior written consent,
such consent not to be unreasonably withheld, cease supplying the Previously
Existing Products to the Owner under this Agreement by

                                      -24-
<PAGE>

delivering six (6) months' prior written notice to the Owner regarding such
cessation; provided that the Vendor will offer to supply to the Owner
           -------- ----
such replacement or substitute Products on terms and conditions pursuant to and
in accordance with subsection 3.3; and provided further that the
                                       -------- -------
New Products or replacement or substitute Products maintain performance and
functionality equivalent to that previously provided by the Previously Existing
Products (unless any such lower performance and/or functionality has been
consented to by the Owner, such consent not to be unreasonably withheld).
Notwithstanding anything stated herein to the contrary, the Vendor will not be
required to provide the Owner notice under this subsection 3.12 or otherwise of
any modification to a Product or a component thereof which in no way affects
the form, fit and/or functionality of such Product.  The Vendor will under no
circumstances be entitled to cease supplying such Previously Existing Products
which are covered under a then unfilled Purchase Order from the Owner.  The
Vendor will have no right to cease supplying the Owner under this subsection
3.12 with any such Previously Existing Products so long as the Vendor continues
to supply and make available such Previously Existing Products to any other
Customer.  It is expressly understood by the Owner that the Vendor does intend,
not earlier than April 1997, to obsolete the QCP-1900 and the CM-D600 models of
Subscriber Units and replace them with a New Product (at the same prices set
forth in Appendix 1) in accordance with this subsection 3.12.  Such New Product
will comply with the specifications as set forth in Exhibit A3.  In accordance
with this subsection 3.12, the Owner does hereby give its written consent to
the substitution of the New Product as specified in Exhibit A3 for any QCP-1900
and/or CM-D600 models of Subscriber Units ordered by the Owner under this
Agreement.

      3.13  [Intentionally Omitted].
             ---------------------

      3.14  Right to Return Products. The Vendor agrees that at any time within
            ------------------------
ninety (90) days immediately prior to the End Date (or the last Business Day of
the Term in the event the End Date should be extended pursuant to the terms of
this Agreement), in the event that items of a Product are not purchased by
Purchasers and remain in the Owner's inventory at such time, the Owner will be
permitted, but not required, to return such items to the Vendor; provided that
the aggregate value of any such Products will not exceed three hundred seventy
five thousand dollars ($375,000)  minus the reasonable actual rework costs
incurred by the Vendor for any such Products which were customized for the Owner
pursuant to and in accordance with the terms of this Agreement. Upon return of
such items to the Vendor, the Vendor will refund to the Owner the price paid for
such items (less such rework costs and less any amounts contributed by the
Vendor to the Co-op Marketing Fund relating to such returned Products) without
charge or penalty or offsetting  such returned items are new, unused, in the
original as shipped by the Vendor to the Owner and are not Previously Existing
Products. Such refund (less such rework costs and less any amounts contributed
by the Vendor to the Co-op Marketing Fund relating to such returned Products)
will be offset against outstanding invoices or, if there are no such invoices,
in cash. Any freight and other charges incurred in connection with returning
such items to the Vendor within such ninety (90) day period will be paid by the
Owner.

      3.15  Labeling and Logo Changes.  (a)  The exterior of each
            -------------------------
Subscriber Unit and its packaging will bear the technology mark, as specified
in Appendix 4, or such other substantially equivalent technology mark as
mutually agreed upon by the Parties (a "Mark").  The Mark will be positioned in
accordance with Appendix 4.  At the Owner's option, and at the Vendor's sole
expense, and with appropriate lead times agreed to by the Parties, each
Subscriber Unit may be otherwise labeled and/or logoed on the front of the
Subscriber Unit below the key pad in accordance with the Specifications.

      (b) The Parties acknowledge that the Owner may want to participate in
certain aspects of the Product labeling and the Vendor agrees to design, upon
mutual agreement with the Owner as to feasibility, timing and additional cost
(subject to the Vendor's obligations as to prices and costs pursuant to
subsection 3.3), if any, associated with any such labeling change not otherwise
at the Vendor's expense pursuant to the terms of this Agreement including, but
not limited to, the Specifications, Product labeling to complement the Owner's
marketing effort in accordance with the Owner's instructions.

      3.16  Materials and Equipment.  Whenever materials are specified or
            -----------------------
described in this Agreement (including the Specifications) by using the name of
a proprietary item or the name of a particular supplier, the naming of the item
is intended to establish the type, function and quality required, and
substitute materials may nonetheless be used, provided that such
                                              -------- ----
materials are equivalent or equal to that named.  If the Vendor wishes to
furnish or use a substitute item, the Vendor must first certify that the
proposed substitute will perform at least as well as the intended functions and
achieve the results called for by this Agreement (including but not limited to
the Specifications), will be substantially similar or of equal substance to
that specified and be suited for the same use as that specified.  The Owner may
require the Vendor to furnish, at the Vendor's expense, additional data about
the proposed substitute as required to evaluate the substitution.  The Owner
will be allowed a reasonable time within which to evaluate each proposed
substitute.  Notwithstanding the foregoing, prior to the shipment of Products
pursuant to the terms of this Agreement, the Vendor may at any time without
notice to or consent of the Owner make changes in a Vendor Product furnished
pursuant to this Agreement, or modify the drawings and published specifications
relating thereto, or substitute Products of similar or later design to fulfill
its obligations under this Agreement or otherwise fill an order, provided
                                                                 --------
that any such changes, modifications or substitutions will in no way have
- - - ----
an adverse affect or otherwise adversely impact upon the form, fit, or function
of an ordered Product pursuant to and in accordance with the applicable
Specifications.  With respect to changes, modifications and substitutions which
do in fact adversely affect the form, fit, or function of an ordered Product
pursuant to and in accordance with the Specifications, the Vendor must notify
the Owner in writing at least ninety (90) days prior to the effective dates of
any such changes, modifications or substitutions.  In the event that any such
change, modification or substitution is not desired by the Owner, the Owner
will notify the Vendor within thirty (30) days from the date of notice and the
Vendor will not furnish any such changed Products to the Owner on any orders in
process at the time the Owner is so notified; provided further, nothing
                                              -------- -------
contained herein will otherwise modify Vendor's obligations under the terms of
this Agreement.

      3.17  Logos.  (a)  The Products will bear only those logos as agreed
            -----
to by the Owner pursuant to the terms of this Agreement (other than the Mark
pursuant to subsection 3.15).  The Products will bear the "Sprint" label or
logo and/or such other labels or logos as the Owner shall require from time to
time, in such size and position on the Products as the Owner shall notify to
the Vendor from time to time pursuant to and in accordance with subsection
3.15.

      (b)  Throughout the Term of this Agreement, the Owner may use only those
trademarks, insignias, logos or other proprietary marks listed on Schedule 6 or
as otherwise consented to in writing by the Vendor ("Proprietary Marks") in
connection with the Owner's sales, advertisements and marketing of the
Products; provided that the Owner's use thereof shall be in accordance
          -------- ----
with the Vendor's, Sony's or Qualcomm's, as applicable, reasonable directions
and policies.  The Owner agrees that it has no rights with respect to the
Proprietary Marks, except as expressly provided in this subsection 3.17(b), and
will not use the Proprietary Marks as part of the business name of the Owner.

      (c)  The Vendor will use its reasonable efforts to cooperate with the
Owner in the development of Product packaging that is fully integrated with the
Owner's branding strategy and which supports the Owner's marketing
communication and segmentation strategy as reasonably communicated to the
Vendor by the Owner from time to time.  Such cooperation will focus on the
contents of Product packaging, the configuration, physical dimensions and
materials of such packaging, communications, colors, graphics and descriptive
language used in connection with such Products and such other items as the
Parties shall agree upon from time to time.

      (d)  If the Vendor is itself unable to meet the Owner's packaging needs
as set forth in subsection 3.17(c) or as otherwise reasonably communicated by
the Owner to the Vendor from time to time, the Vendor agrees to supply the
Products in specified configurations and bulk packaging to the Owner's
designated packager for the required packaging; provided that in such
                                                -------- ----
case the Vendor will credit the Owner against the purchase price for the
subject Products with any amounts saved by the Vendor for not having had to
perform the packaging services as required by the Specifications.

      3.18  New Development Advisory Board; Notice of New Developments.
            ----------------------------------------------------------
The Owner and the Vendor will establish an NDAB within sixty (60) days of the
Effective Date.  The purpose of the NDAB will be to review the development
requirements and high level development milestones, to ensure that the Vendor
understands the Owner's requirements for each Product (including New Products)
and/or enhancements.  The NDAB will provide an executive forum to discuss
product ideas, Owner requirements and its recommended development
prioritization for improved infrastructure-based subscriber features.  The
focus of the NDAB will be on Product features, new CDMA products, Product
Enhancements, critical operational issues, future developments beyond CDMA
cellular without the need for System additions and on such other matters as the
Parties mutually agree upon from time to time.  Throughout the Term, the Vendor
will use its reasonable efforts to provide the Owner notice of its
technological innovations

                                      -27-
<PAGE>

and advancements relevant to the Products within a time reasonably prior to
making any such information generally available to its Customers, provided
                                                                  --------
that nothing herein will require the Vendor to disclose any information
- - - ----
proprietary to any other Customer.

      3.19  Market Development Manager.  The Vendor will provide a market
            --------------------------
development manager to coordinate the efforts of the Vendor in meeting its
obligations relating to the NDAB who will specifically focus on new Products,
CDMA services and features.  Such market development manager must be reasonably
knowledgeable in CDMA technology and the Owner's Nationwide Network and must
work closely, and on a regularly scheduled basis, with the Owner's senior
engineering and marketing personnel on feature development, feature roll-out,
future road maps for CDMA Products, and any other marketing aspect of providing
PCS that the Owner believes is beneficial to the Nationwide Network and/or any
PCS System and/or Products at such time.  The Vendor's market development
manager and the manager's staff will serve as the Owner's direct liaison with
the Vendor to advise the Vendor's product development teams of the Owner's
priorities as described to the Vendor by the Owner from time to time either
through the NDAB or by any other means acceptable to the Parties.  Nothing
contained in this subsection 3.19 will in any way limit and/or modify the
Owner's ability to enforce its rights under this Agreement or to otherwise
maintain contacts with the Vendor in any other way it sees fit.  Within a
reasonable time after the Effective Date the Owner will use reasonable efforts
to designate appropriate personnel to coordinate with the Vendor's market
development manager pursuant to this subsection 3.19.

      3.20  Applicable Law and Radio Frequency Energy Standards.  All
            ---------------------------------------------------
Products must comply, to the extent applicable, with all Applicable Law as of
their respective date of delivery to the FOB point including, but not limited
to, the requirements of Subpart J of Part 15 of the rules and regulations
promulgated by the FCC, as the same may be amended from time to time (the "FCC
Rules and Regulations"), including, without limitation, those provisions
concerning the labeling of Products and the suppression of radio frequency and
electromagnetic radiation to specified levels.  In the event that the Products
produce radio frequency interference, notwithstanding that such Products comply
with the FCC Rules and Regulations, the Vendor will use reasonable efforts to
provide the Owner with reasonable technical information in its possession on
the methods to suppress such interference and will exercise reasonable
commercial efforts to isolate and remediate any such radio frequency
interference caused by the Products which constitutes a condition materially
adversely affecting the Nationwide Network (a "RF Interference Condition") or
any part thereof, provided that the Owner will cooperate to the extent
                  -------- ----
reasonable with the Vendor to achieve such remediation.  Nothing in this
subsection 3.20 will be deemed to diminish or otherwise limit the Vendor's
warranty obligations pursuant to this Agreement.

      3.21  [Intentionally Omitted].
            -----------------------

      3.22  Test Products; Product Verification and Testing.  (a) The
            -----------------------------------------------
Vendor agrees to supply the Owner with ten (10) pre-production items of each
Subscriber Unit and Material Accessory no later than five (5) Business Days
after the Effective Date and ten (10) additional pre-production items of each
Subscriber Unit and Material Accessory no later than July 31, 1996 in order to
allow the Owner to test such items to determine whether such Subscriber Units
and Material Accessories comply with the requirements of this Agreement,
including the Specifications; provided that no such tests or any such
                              -------- ----
knowledge or experience gained or otherwise acquired from such tests or
otherwise will in any way be deemed a waiver of or to reduce or affect the
Vendor's obligations with respect to the provision of warranties pursuant to
this Agreement.  The Owner will use reasonable efforts to provide the Vendor
with the results of such tests.  In the event of the Vendor's introduction of
New Products pursuant to the terms of this Agreement, the Vendor will provide
the Owner reasonably sufficient numbers of pre-production units (in any event
not more than ten (10)) of any such New Product for the purposes of Owner
testing at least ninety (90) days prior to the general market availability of
any such New Products.  Notwithstanding anything stated herein to the contrary,
the warranties set forth in subsections 3.7 and 3.8 will not apply to any
pre-production Subscriber Units required to be delivered by the Vendor pursuant
to this subsection 3.22(a) or otherwise purchased by the Owner.  Exhibits B1
and B2 are preliminary and subject to final revision as mutually agreed to by
the Parties in good faith; provided that Exhibits B1 and B2 will be
                           -------- ----
finalized no later than July 15, 1996; provided further that in the
                                       -------- -------
event the Parties are unable to mutually agree in good faith by July 15, 1996
such disagreement will be immediately referred to dispute resolution pursuant
to and in accordance with the terms of subsection 11.8.

      (b)   The Vendor will test the Products and verify to the Owner their
performance in accordance with the Specifications pursuant to and in accordance
with the requirements and milestones set forth in Exhibits B1, B2 and B3.  The
failure of the Vendor to verify the performance of the Products pursuant to the
requirements of Exhibits B1, B2 and B3 will result in the Owner having the
absolute right to suspend or cancel (in its sole and absolute discretion) any
then existing or future Purchase Orders for any such Products which have not in
fact complied with the requirements of Exhibits B1, B2 and B3.  To the extent
any class, category or type of Products do not comply with the requirements of
Exhibits B1, B2 and B3 within ninety (90) days (one hundred forty (140) days in
the event a semiconductor component modification is required) of the testing
dates provided for any such verifications pursuant to Exhibits B1, B2 and B3
(in the case of Exhibit B3 at the Vendor's testing facility), the Owner will
have the right, but not the obligation, to terminate this Agreement without
payment or penalty of any kind; provided that at any time after the
                                -------- ----
first thirty (30) days of any such applicable cure period as set forth above in
this sentence, the Owner will have the right, in addition to any other rights
set forth in the immediately preceding sentence, to cancel (in its sole and
absolute discretion) any then existing Purchase Orders for Products delivered
or required to be delivered on such date which have not in fact complied with
the requirements of Exhibits B1, B2 or B3 and the Vendor agrees to reimburse
the Owner

                                      -29-
<PAGE>

for any and all reasonable direct out of pocket expenses and costs in excess of
any expenses and costs the Owner would have otherwise incurred hereunder in
reasonably replacing (using replacement Products with the most comparable
specified features and functionality available at such time) any such Products.
In the event that the Owner chooses to terminate this Agreement pursuant to
this subsection 3.22(b) such termination will be the Owner's sole and exclusive
remedy; provided that in the event the Owner does not terminate under
        -------- ----
this subsection 3.22(b), the Owner will retain all rights to enforce any and
all delay penalties against the Vendor pursuant to and in accordance with
subsection 4.2 as its sole and exclusive remedy in such case; provided
                                                              --------
further that nothing contained herein will be deemed to diminish or
- - - -------
otherwise limit the Vendor's warranty obligations pursuant to this Agreement.
Notwithstanding anything to the contrary stated herein above, to the extent
that the Owner decides (in its sole and absolute discretion) to take, delivery
of and place into service any such Products which have failed to pass the
testing required by Exhibits B1, B2 or B3 ("Non-Conforming Products"), the
Owner will be deemed to have accepted any such Non-Conforming Products with any
such non-conformance; provided that, in such case, the Owner will in no
                      -------- ----
way be deemed to have waived any of its rights to enforce the Vendor's complete
conformance (including, but not limited to, conformance with any requirement
not otherwise met by such Non-Conforming Products) with the testing
requirements set forth in Exhibits B1, B2 and B3 and the Specifications on all
other Products (except for previously delivered and accepted Non-Conforming
Products) already then delivered or yet to be delivered by the Vendor pursuant
to the terms of this Agreement.

      3.23  Change Orders.  From time to time the Owner may request changes
            -------------
or modifications to the Products or packaging and/or the Specifications
("Change Orders").  All such Change Orders requested in writing by the Owner to
the Vendor will be subject to the reasonable good faith and timely agreement
(including, but not limited to, agreement on terms such as one-time charges,
price increases, minimum purchase commitments and schedule impacts) of the
Vendor and the Owner which agreement will be evidenced by a writing executed by
an authorized representative of each of the Parties.

      SECTION 4.  LEAD TIMES AND DELAY

      4.1  Lead Times.  Provided that the Owner submits Forecasts to the
           ----------
Vendor and places Purchase Orders for Products in accordance with Section 5
below and subject to the provisions of subsection 3.2(a), the Vendor will ship
Products (other than as specified in the last sentence of this subsection 4.1)
ordered by the Owner against such Forecasts within the later of (i) ten (10)
Business Days after receipt and the Vendor's acknowledgement of the Owner's
Purchase Order therefor, and (ii) the shipment date specified by the Owner in
such Purchase Order pursuant to subsection 5.2(a); provided that the
                                                   -------- ----
Vendor has acknowledged receipt of such Purchase Order, and the time period
from the date of the Vendor's acknowledgement and the specified shipment date
is longer than ten (10) Business Days.  The Vendor will be able to provide the
Owner with specific lead times (which will in no event be in excess of ten (10)
days from receipt and acknowledgement by the Vendor of the Owner's Purchase
Order subject to the terms of

                                      -30-
<PAGE>

the first sentence of this subsection 4.1) applicable to each Purchase Order
for Products at the time the Vendor receives and acknowledges the Owner's
Purchase Order therefor.  The Vendor will ship Products maintained in the
Buffer Stock ordered by the Owner against Forecasts for such Buffer Stock in
accordance with the provisions set forth in subsection 5.2.

      4.2 Delivery Delay. (a) With respect to the first [   ] Subscriber Units
          --------------
(and their included Material Accessories) purchased hereunder (the "Launch
Units"), in the event that the Vendor fails to deliver the Launch Units within
[       ] days (the "Delay Grace Period") of the applicable dates for shipment
referred to in subsection 4.1, the Vendor will pay to the Owner as liquidated
damages for such late performance (i) for each of the first [        ] days
beyond such Delay Grace Period, an amount equal to [   ] per day (for such
[         ] day period) of the total price of such undelivered Launch Units and
(ii) on the thirty fourth day after the date set for shipment pursuant to
subsection 4.1, an amount equal to [   ] of the total price of such undelivered
Launch Units; provided that in no event will the Vendor incur aggregate damages
              -------- ----
with respect to Launch Units under this subsection 4.2(a) in excess of [   ] and
further, in no event will the Vendor incur damages with respect to Launch Units
on any given day pursuant to this subsection 4.2(a) in excess of [   ] per day;
provided further, that no such liquidated damages for delivery delay will be due
- - - -------- -------
if the delay is attributable solely to (i) an event constituting a Force Majeure
pursuant to the terms of this Agreement or (ii) an act or omission of the Owner.
The Owner may offset the amount of such delay penalty against any amounts owed
to the Vendor for Products supplied under this Agreement.

      (b)  With respect to Subscriber Units (and their included Material
Accessories) that do not constitute Launch Units, for each of the first [
   ] days beyond the applicable "Succeeding Delay Grace Period" that the Vendor
fails to deliver any Subscriber Units (and their included Material
Accessories), the Vendor will pay to the Owner as liquidated damages for such
late performance an amount equal to [   ] per day (for such [     ] day period)
of the total price of such Subscriber Units (and included Material Accessories)
up to an amount not to exceed, in aggregate, [   ] of the total price of such
Subscriber Units (and included Material Accessories); provided that no such
                                                      -------- ----
liquidated damages for delivery delay will be due if the delay is attributable
solely to (i) an event constituting a force majeure pursuant to the terms of
this Agreement or (ii) an act or omission of the Owner. The Owner may offset the
amount of any delay penalty against any amounts owed to the Vendor for Products
supplied under this Agreement. For the purposes hereof, Products that will have
been rightfully rejected by the Owner in accordance with the terms of this
Agreement will not be deemed to be delivered by the Vendor; provided that
                                                            -------- ----
liquidated damages for delivery delay will not accrue during the time it takes
the Owner to inspect and reject any such Products. For the purposes of this
subsection 4.2(b) "Succeeding Delay Grace Period" shall mean [     ] days
beyond the applicable dates for shipment referred to in subsection 4.1.

                                      -31-
<PAGE>

      (c) Notwithstanding anything stated in this subsection 4.2 to the
contrary, during any time that the Owner is in default under this Agreement for
undisputed payments owed to the Vendor, the Owner will not be entitled to any of
the delay penalties set forth in this subsection 4.2, nor shall any such delay
penalties accrue during the period any such default remains outstanding.
Furthermore, in the event that on the last day of the Initial Term the Owner's
aggregate Shortfall over the Initial Term exceeds [   ] of the Total Minimum
Commitment, the Owner will, within (30) days of receiving an invoice from the
Vendor, refund to the Vendor any delay penalties collected by the Owner pursuant
to this subsection 4.2 (or if such delay penalties have accrued but have not yet
been paid, the obligation to pay such penalties shall be absolved); provided
                                                                    --------
that in no event will the Owner be obligated to make any such refund if the
- - - ----
Owner's Shortfall was reasonably due to the Vendor's delivery delays throughout
the Initial Term.

      (d)  No liquidated damages for delivery delays under subsection 4.2 will
accrue (nor will the Owner be entitled to exercise any other remedies set forth
herein with respect to the enforcement of timely delivery) with respect to any
Subscriber Units not timely delivered by the Vendor (the "Delayed Products")
(i) to the extent, and only to the extent, that the Delayed Products were
intended for distribution and use in the first System Area in which the Owner
plans (in its sole and absolute discretion) to commence commercial operation
("Commencement") having more than [   ], (ii) if the Commencement of the First
System would have been delayed, even with timely delivery of the Delayed
Products beyond that date the Owner anticipated Commencement was to occur when
the Owner ordered the Delayed Products (the length of such delay being the
"Delay Period"), (iii) the Delayed Products are delivered before the end of the
Delay Period and (iv) the Owner, in such instance, will have given the Vendor
prior written notice of such Commencement delay. The Owner agrees to promptly
give the Vendor written notice of any delay in Commencement. It is the intent of
the Parties that the length of the Delay Period be equal to the number of days
from the date the Owner anticipated Commencement was to occur when the Owner
ordered the Delayed Products until the date Commencement would have occurred
assuming that the Owner had received the Delayed Products. For the purpose of
subsection 4.2(a), liquidated damages for delivery delays will be calculated
with respect to Delayed Products by using the day following the last day of the
Delay Period as the date on which the Delayed Products were to have been
delivered by the Vendor. It is expressly understood and agreed that this
subsection 4.2(d) will only apply to Products ordered by the Owner for the First
System and that the Vendor will not be entitled to the benefits of this
subsection 4.2(d) for any other Products or any other System Area to or for
which Products are to be shipped pursuant to the terms of this Agreement.

      (e)  In the event (i) there are delivery delays in any given Annual
Supply Period, or the Stub Period, as the case may be, which Vendor fails to
cure within the applicable Delay Grace Period, which delivery delays involve
the Vendor's failure to timely deliver more than [   ] Subscriber Units, in
aggregate, and (ii) the percentage of deliveries of Subscriber Units which are
subject to delivery delays in any given Annual Supply Period, or the Stub
Period, as the case may be, and which Vendor fails to cure

                                      -32-
<PAGE>

within the applicable Delay Grace Period, exceeds [   ], provided that in any
                                                         -------- ----
event the actual number of delivery delays referenced in the immediately
proceeding clause (ii) will be at least [   ] of the number of scheduled
deliveries, then the Owner will have the right, but not the obligation, to
terminate this Agreement without any payment or penalty. In the event the Vendor
fails to cure any delivery delay within thirty (30) days from the date delivery
was due, the Owner will have the right, but not the obligation, to cancel the
Purchase Order subject to such delay without any payment or penalty. With
respect to any such cancelled Purchase Order, the Owner will be entitled to
receive from the Vendor any and all reasonable direct out of pocket expenses and
costs in excess of any expenses and costs the Owner would have otherwise
incurred hereunder in order to reasonably fulfill (using replacement products
with the most comparable features and functionality) such cancelled Purchase
Order with any third party supplier acceptable to the Owner.

      (f)  Notwithstanding anything in this subsection 4.2 to the contrary, the
Vendor will only be obligated to pay to the Owner one-half (1/2) of the Delay
Penalties otherwise applicable to the late delivery of Products ordered
pursuant to an Excess Purchase Order.

      (g)  In the event the Owner exercises its rights under this subsection
4.2 due to a Vendor delivery delay, the remedies for any such Vendor delivery
delay as set forth in this subsection 4.2 will be exclusive.

      SECTION 5.  FORECASTS AND ORDERING

      5.1  Forecasts.  (a)  Upon execution of this Agreement and on the
           ---------
first of each month thereafter, the Owner will deliver to the Vendor written
forecasts (a "Forecast") specifying its estimate of the quantity of each type
of Product that it expects to purchase on a month to month basis during the
twelve (12) months following the date of such Forecast (a "Forecast Period"),
which shall, subject to the provisions of subsection 3.2(a), be treated as
follows;

             (i)  quantities forecasted to be ordered during the first three
                  (3) months of each Forecast Period will be a firm Purchase
                  Order which, pursuant to the terms of this Agreement, must be
                  taken by the Owner in the month indicated.  The Owner will
                  place one or more Purchase Orders to purchase Products in
                  accordance with the applicable Forecast;

            (ii)  quantities forecasted to be ordered during month four (4) of
                  each such Forecast Period shall be considered reasonably
                  accurate estimates of prospective Purchase Orders and
                  accordingly, the Owner will issue the Vendor firm Purchase
                  Orders to ensure that at least eighty percent (80%) and not
                  more than one hundred twenty percent (120%)
                  of the quantities specified during this segment of

                                      -33-
<PAGE>

                  the Forecast Period are covered by firm Purchase Orders from
                  the Owner;

           (iii)  quantities forecasted to be ordered during month five (5) of
                  each such Forecast Period shall be considered reasonably
                  accurate estimates of prospective Purchase Orders, and
                  accordingly, the Owner will issue the Vendor firm Purchase
                  Orders to ensure that at least sixty percent (60%) and not
                  more than on hundred forty percent (140%)
                  of the quantities specified during this segment of the
                  Forecast Period are covered by firm Purchase Orders from the
                  Owner; and

            (iv)  quantities forecasted to be ordered during months six (6)
                  through twelve (12) of each such Forecast Period will only be
                  estimates of prospective Purchase Orders, and subsequent
                  Forecasts and actual Purchase Orders may completely vary and
                  be completely changeable by the Owner in its absolute
                  discretion.

            Any reductions in firm Purchase Orders below the specified
forecasted amounts or any increases in firm Purchase Orders above the specified
forecasted amounts pursuant to clause (iii) of this subsection 5.1(a) may, in
the Owner's sole discretion, be cumulative with any such increase or decrease
pursuant to clause (ii) of this subsection 5.1(a).  For example, if a
forecasted amount for month five in any forecast is subsequently reduced by the
Owner by forty percent (40%) pursuant to clause (iii) of this subsection 5.1(a)
the Owner will have the right, but not the obligation, to further reduce such
reduced amount by an additional twenty percent (20%) pursuant to clause (ii) of
this subsection 5.1(a).  The first Forecast to be delivered by the Owner to the
Vendor is attached hereto as Schedule 8 and is expressly accepted by the Vendor.
Except with respect to such first Forecast, in no event will the Vendor be
required to accept an amount in any given month of a Forecast which is greater
than one hundred fifty percent (150%)of the average amount forecasted by the
Owner for the five months immediately preceding the subject month.  In the event
the Owner fails to deliver to the Vendor a new Forecast by the first Business
Day of any given month, then the new Forecast for such new twelve month period
shall be deemed to be the prior Forecast, adjusted by shifting the monthly
quantities up one month (i.e, the quantity that used to be forecasted for month
two will instead be the quantity for month one) with the new amount forecasted
for month twelve being the same as the amount for the new month eleven.
Notwithstanding anything set forth in this Agreement, in no event shall the
Owner be entitled to increase the amount of Products forecasted in the months of
July through December, 1996 above the amounts forecasted for any such month in
the first Forecast.

            (b)  Within any Forecast provided to the Vendor by the Owner
pursuant to and in accordance with the terms of this subsection 5.1, the Owner
may designate to the Vendor a certain percentage of each type of the Product
requirements so forecasted ((i) up to fifteen percent (15%) in the Owner's sole
discretion during the first Annual Supply

                                      -34-
<PAGE>

Period and (ii) up to ten percent (10%) in the Owner's sole discretion during
any succeeding Annual Supply Period, or the Stub Period, as the case may be) to
be held by the Vendor in separate buffer stock ("Buffer Stock") for accelerated
ordering and shipment of such Products within such Buffer Stock.  In the event
of any such designation pursuant to this clause (b) of subsection 5.1, the
Vendor will maintain such Buffer Stock and deliver to the Owner any Products
within such Buffer Stock in accordance with the lead times and ordering
provisions for such Buffer Stock set forth in this Agreement.

      (c)  The Forecasts will be in a format mutually acceptable to the
Parties; provided that the format of the first Forecast as set forth in
         -------- ----
Schedule 8 will at all times be deemed in a format acceptable to both Parties.

      5.2  Ordering.  (a)  In order to be effective, all orders by the
           --------
Owner for Products will be made by the Owner in the form of written Purchase
Orders, specifying the quantity of each type of Product to be purchased and the
date or dates on which such Products are required to be shipped to the Owner,
the shipping method and the location to which such Products should be shipped;
provided that such shipment date will be no earlier than (i) ten (10)
- - - -------- ----
Business Days after the date of such Purchase Order in the event of Purchase
Orders for Products not in Buffer Stock, (ii) one (1) Business Day for not more
than (x) [   ] Subscriber Units (with accompanying Accessories) and not
exceeding (y) [   ] separate destinations to which Products will be shipped as
designated by the Owner in Purchase Orders (each such destination a
"Shipped-to Location") for Products in Buffer Stock and (iii) two Business Days
for not more than (x) [   ] Subscriber Units (with accompanying Accessories)
and not exceeding (y) [   ] separate Shipped-to Locations for Products in
Buffer Stock; and provided further that the Vendor will use its reasonable
                  -------- -------
efforts to fulfill Purchase Orders in excess of forecasted quantities that the
Owner is entitled to turn into firm Purchase Orders pursuant to and in
accordance with subsection 5.1 (each an "Excess Purchase Order"). Each Purchase
Order will be submitted to the Vendor, 10300 Campus Point Drive, San Diego, CA
92121, Attn: Sprint Spectrum L.P. Account Manager (or any other authorized
representative of the Vendor designated to the Owner in writing by the Vendor
from time to time) and will be subject to the acknowledgement by the Vendor in
writing to the designated authorized representative of the Owner within two (2)
Business Days of receipt of Purchase Orders for Products in Vendor stock and
within one (1) Business Day of receipt of Purchase Orders for Products in Buffer
Stock. The Vendor will acknowledge Purchase Orders that the appropriate
personnel of the Vendor have actual knowledge of. Subject to the immediately
preceding sentence, failure of the Vendor to acknowledge to the Owner in writing
receipt of any Purchase Order or Excess Purchase Order shall be deemed to render
any such Purchase Order or Excess Purchase Order null and void. Within ten (10)
Business Days of receipt of Purchase Orders for Products in Vendor stock and
within one (1) Business Day of receipt of Purchase Orders for Products in Buffer
Stock, the Vendor will (subject to the terms of the last three sentences of this
subsection 5.2(a)) have the right to reject for non-conformance with the terms
of this Agreement any such Purchase Orders the receipt of which it has

                                      -35-
<PAGE>

acknowledged pursuant to the terms set forth above; provided that for
                                                    -------- ----
any acknowledged Purchase Orders which must be fulfilled within one (1)
Business Day pursuant to clause (ii) above, the Vendor must reject for such
non-conformance any such Purchase Order on the same day as the acknowledgment
of such Purchase Order.  The failure of the Vendor to so reject Purchase Orders
within the time frames above will be deemed acceptance by the Vendor of any
such acknowledged Purchase Orders.  The Vendor will not have the right to
disagree with, reject, modify or otherwise amend any Purchase Order in
conformance with the terms of this Agreement including, but not limited to,
quantities which have already been the subject of Forecasts by the Owner
pursuant to the terms of subsection 5.1; provided that subject to the
                                         -------- ----
terms of the immediately preceding sentence of this subsection 5.2(a), the
Vendor may reject or otherwise respond to any Excess Purchase Order,
provided that failure of the Vendor to respond to any such acknowledged
- - - -------- ----
Excess Purchase Order within ten (10) days of receipt thereof will be deemed
acceptance thereof.  Any Vendor rejection of or modification to a Purchase
Order (other than Excess Purchase Orders) in conformance with the terms of this
Agreement pursuant to and in accordance with subsection 5.1 will be deemed a
material breach of this Agreement by the Vendor.  Notwithstanding subsection
5.2(f) below, to the extent that the Vendor is actually aware that any Purchase
Order in any way contradicts or is not otherwise in conformance with the terms
of this Agreement, the Vendor agrees to promptly notify the Owner of any such
contradiction or non-conformance as soon as possible upon becoming actually
aware of such contradiction or non-conformance so that the Owner will have a
reasonable opportunity to correct any such contradiction or non-conformance and
furthermore to the extent reasonable under the circumstances the Vendor will
endeavor to fulfill any such non-conforming Purchase Order ignoring any such
non-conformity unless the Owner, after notification from the Vendor, will have
expressly refused to accept the fulfillment of such Purchase Order with any
such correcting modification.

      (b)  [Intentionally Omitted]

      (c)  Subject to subsections 3.2(b) and 3.2(c), any Purchase Order or
Excess Purchase Order may, in the Owner's sole and absolute discretion, be
postponed once without penalty by written notice from the Owner to the Vendor
at any time prior to ninety (90) days immediately prior to the initial shipment
date established for such Purchase Order pursuant to the terms of this
Agreement for a period not in excess of ninety (90) days from such initial
shipment date.  If the Owner chooses to postpone a Purchase Order (for a period
not in excess of ninety (90) days from the initial shipment date for such
Purchase Order) at any time within the ninety (90) days immediately prior to
the initial shipment date (a "Late Postponement"), the Owner will pay to the
Vendor an amount equal to [   ] of the value (based upon the prices set forth in
Appendix 1) of any increased Product inventory for each month or portion of a
month (such amount to be prorated if such time periods are not whole months) the
Vendor is required to carry such increased Product inventory due to such Late
Postponement. The Vendor will invoice any such amounts on a monthly basis. In
any event and notwithstanding anything to the contrary in this clause (c) of
subsection 5.2, no Purchase Order or Excess Purchase Order may be postponed by
the Owner (i) within (10)

                                      -36-
<PAGE>

Business Days of the initial shipment date for such Purchase Order or Excess
Purchase Order or (ii) if an Owner Event of Default has occurred or is
continuing pursuant to subsection 10.8.

      (d)   In accordance with the terms of subsection 5.1(b), the Vendor will
maintain Buffer Stock of Products which, when ordered by the Owner from the
Vendor in accordance with the Owner's Forecasts, will be delivered to the Owner
in accordance with the terms of subsection 5.2(a).  The Owner will be liable
for and will pay to the Vendor an amount equal to [   ] of the value
(based upon the prices set forth in Appendix 1) of such Buffer Stock held in the
Vendor's inventory for each month or portion of a month (such amount to be
prorated if such time periods are not whole months) such Buffer Stock is so held
by the Vendor in its inventory in excess of thirty (30) days from the date the
Vendor commenced holding any such Buffer Stock for the Owner pursuant to and in
accordance with subsection 5.1 (each such date a "Buffer Stock Commencement
Date"); provided that during the first Annual Supply Period the Owner will
        -------- ----
not be liable for any such amounts during the first thirty (30) day period
commencing upon the applicable Buffer Stock Commencement Date.

      (e)  The Vendor will reasonably cooperate with the Owner, and/or any
Person designated by the Owner for such purpose, (i) to utilize UPC stock
control numbering and other bar-coding requirements relating to inventory
processes and systems, and (ii) to develop processes and systems that will
maximize delivery logistics.  Metric targets will be defined by the mutual good
faith agreement of the Parties for acceptable stock out percentages, delivery
times and total logistics costs.

      (f)  Unless the Parties otherwise expressly agree in writing, each
Purchase Order will be deemed to incorporate by reference all of the terms and
conditions of this Agreement.  Should the terms of any Purchase Order conflict
with the terms of this Agreement, the terms of this Agreement will govern
unless the Parties expressly agree in writing (signed by a duly authorized
representative of both Parties) to the contrary.  This Agreement will continue
to apply to a Purchase Order during the Term of this Agreement until all
obligations herein and thereunder are performed.

      SECTION 6.  SALES AND TECHNICAL SUPPORT

      6.1  Sales Training.  The Vendor will work with the Owner, at the
           --------------
Vendor's sole expense, to agree on a sales training program for the
distribution channel used by the Owner for Subscriber Units.  The goal of this
program will be to provide sales training ("Training") to the Owner's personnel
on CDMA and the features of the Subscriber Units, as well as to provide
appropriate Product related collateral material.  The training program will
include, but will not be limited to, the following topics:  CDMA; Product
features and usage; Subscriber Unit programming, installation and
troubleshooting; and such other matters as the Parties may reasonably agree
upon from time to time.  The target audiences for the training will be the
Owner's marketing and sales personnel.  These training programs will take place
at mutually agreeable locations (such locations to be provided at the Owner's
sole expense) in each of the Owner's System Areas at

                                      -37-
<PAGE>

least once a year for the first two (2) years after introduction of the
Subscriber Units, at no charge to the Owner.  Such training program will last
for a period of time as reasonably agreed upon by the Parties.  The Vendor
anticipates that the Owner may want to influence aspects of the training and
will design the CDMA training program to complement the Owner's marketing and
sales effort.  Should the Owner request the Vendor to modify the program in
such a way as to increase the Vendor's actual expenses, the Owner and the
Vendor will negotiate the terms and conditions of implementing the Owner's
request in good faith.

      6.2  Sales and Promotional Efforts.  (a) In order to ensure that the
           -----------------------------
relationship between the Parties contemplated by this Agreement will be
mutually advantageous, and in recognition of the expertise and commitment by
the Parties necessary for the effective marketing and support of the Products,
the Owner agrees to encourage and develop the sales potential for such
Products, to employ competent personnel to meet the demands and needs for
marketing and support of the Products, and to encourage the purchase of
Products by Agents and Purchasers.  Nothing contained in this subsection 6.2(a)
will in any way limit or otherwise modify the Vendor's obligations under this
Agreement.

      (b)  In order to assist the Owner to promote sales of the Products, the
Vendor will furnish the Owner, at the Vendor's sole expense, Vendor catalogs,
point of sales literature, training documentation, printed technical
information, data sheets and other reasonable advertising materials in such
quantities and at such time as may be reasonably agreed to by the Parties.

      (c)  If the Owner reasonably requires customized Vendor sales and
training literature, the content of the Vendor's appropriate existing
literature will be provided to the Owner, in the Owner's discretion, at the
Vendor's sole expense, in electronic form, or CD-ROM format or artwork to allow
the Owner to produce literature and promotional pieces that are of the Owner's
style and name.  The use of any such literature will be subject to the
guidelines established between the Parties pursuant to subsection 8.1(b).  In
addition, the Vendor agrees to grant the Owner a world-wide non-exclusive
royalty-free license to reprint any Vendor-owned sales literature in connection
with the Owner's sales, advertising and promotion of the Products.  In
addition, the Vendor agrees to grant the Owner a non-exclusive royalty-free
license to distribute within the Territory any of the Vendor's own sales
literature in connection with the Owner's sales, advertising and promotion of
the Products; provided that in the event any such literature is in fact
              -------- ----
distributed outside of the Territory by any Person other than the Owner (or by
an agent or affiliate of the Owner acting on the Owner's behalf or upon the
Owner's direction), the Vendor will not, in such event, take any action for
damages of any nature against the Owner under this Agreement or otherwise.

      (d)  The Vendor and the Owner agree to reasonably cooperate with each
other in the areas of sales and marketing in support of sales of the Vendor's
Products to customers of the Owner's telecommunications services.

      SECTION 7.  INTELLECTUAL PROPERTY

      7.1  Intellectual Property Rights Infringement.  Subject to the
           -----------------------------------------
provisions of subsections 7.3 and 7.4, the Vendor agrees that it will defend,
at its own expense, all suits and claims against the Owner, its affiliates,
directors, officers, agents and employees  for infringement or violation
(whether by use, sale or otherwise) of any patent, trademark, copyright, trade
secret or other intellectual property rights of any third party (collectively,
"Intellectual Property Rights"), arising under or in connection with Applicable
Law within the Territory covering, or alleged to cover, the Products or any
component thereof for its intended use, in the form furnished or as
subsequently modified by the Vendor.  The Vendor agrees that it will pay all
sums, including, without limitation, attorneys' fees and other costs, which, by
final judgment or decree, or in settlement of any suit or claim to which the
Vendor agrees, may be assessed against the Owner on account of such
infringement or violation, provided that:
                           -------- ----

             (i)  the Vendor will be given prompt written notice of all claims
                  of any such infringement or violation and of any suits or
                  claims brought or threatened against the Owner or the Vendor
                  of which the Owner has actual knowledge;

            (ii)  the Vendor is given full authority to assume control of the
                  defense (including appeals) thereof through its own counsel
                  at its sole expense and will have the sole right to settle
                  any suits or claims without the consent of the Owner;
                  provided that the Vendor has no right and will have
                  -------- ----
                  no right to agree to injunctive relief against the Owner;
                  provided further that the Vendor will notify the
                  -------- -------
                  Owner of any proposed settlement prior to the Vendor's
                  acceptance of such settlement; and

           (iii)  the Owner will cooperate fully with the Vendor in the defense
                  of such suit or claims and provide the Vendor, at the
                  Vendor's expense, such assistance as the Vendor may
                  reasonably require in connection therewith.

      7.2  The Vendor's Obligation to Cure.  If in any such suit so
           -------------------------------
defended all or any part of the Products or the Software or any component
thereof is held to constitute an infringement or violation of Intellectual
Property Rights and its use is enjoined, or if in respect of any claim of
infringement or violation the Vendor deems it advisable to do so, the Vendor
will, within one hundred twenty (120) days, at its sole cost, expense and
option take one or more of the following actions:  (i) procure the right to
continue the use of the same without interruption for the Owner; (ii) replace
the infringing Product, Software or component with a noninfringing product,
noninfringing Software or a non-infringing component, as applicable, that meets
the Specifications; or (iii) modify said Product, Software or any component
thereof so as to be noninfringing, provided that the Product, Software
                                   -------- ----
or any component thereof as modified meets all of the Specifications.  In the
event that the Vendor is not able, using reasonable commercial efforts, to cure

                                      -39-
<PAGE>

the infringement pursuant to clause (i), (ii) or (iii) in the immediately
preceding sentence, the Vendor will refund to the Owner the full purchase price
paid (less Product Depreciation and less any amounts contributed by the Vendor
to the Co-op Marketing Fund relating to such Products) by the Owner for such
infringing Product, and the Owner will, if requested by the Vendor, use
reasonable efforts to return, at the Vendor's sole cost and expense, any such
infringing Products which are then available to it; provided that the
                                                    -------- ----
Vendor will have first refunded any such monies for such infringing

Products to the Owner.  The obligations of the Vendor under subsection 7.1 and
the remedies under this subsection 7.2 will be the sole and exclusive
obligations of the Vendor and the sole and exclusive remedies available to the
Owner against the Vendor in the event of a claim against the Owner which is
covered by subsection 7.1 above.

      7.3  The Vendor's Obligations.  The Vendor's obligations under this
           ------------------------
Section 7 will not apply to (i) any infringement or violation of Intellectual
Property Rights caused by modification of any Product, Software or any
component thereof by any Person other than the Vendor, its employees or agents
acting on the Vendor's behalf or at its direction, or (ii) any infringement
caused directly by any such Person's use and maintenance of such Product other
than in accordance with the Specifications and the purposes contemplated by
this Agreement for use in the Owner's Nationwide Network, except as expressly
authorized in writing by the Vendor.  The Vendor's obligations under subsection
7.1 will not extend to alleged infringements or violations that arise because
the Products provided by the Vendor are used in combination with other products
(other than Infrastructure Equipment) furnished by third parties and where any
such combination was not installed, recommended or approved, expressly in
writing by the Vendor; provided that in no event will the Owner seek
                       -------- ----
indemnification against the Vendor under this Section 7 for an infringement
claim based upon any such combination of Products with Infrastructure Equipment
to the extent and only to such extent the Owner is covered by an indemnity
under a then existing Procurement and Services Contract.  The Vendor's
indemnification obligations specified in this Section 7 will not apply to any
intellectual property infringement caused directly by an Owner Defined Feature.
Nothing contained herein to the contrary will in any way constitute a waiver or
modification of the Vendor's rights to enforce its intellectual property rights
against third parties.

      7.4  The Owner's Obligations.  The Owner agrees that it will defend,
           -----------------------
at its own expense, and indemnify and hold harmless the Vendor, its affiliates,
directors, officers, agents, employees and successors, from and against all
suits and claims for infringements or violations of any patent, trademark,
copyright, trade secret or other intellectual property rights of any third
party (i) caused directly by the Owner's (or by an affiliate's or agent's if
done at the direction of the Owner) modification, use or maintenance of any
Product other than in accordance with the Specifications and the terms of this
Agreement or the Vendor's written authorization, (ii) to the extent that any
Owner Defined Feature directly gives rise to an intellectual property
infringement claim against the Vendor, its affiliates, directors, officers,
agents, employees and successors, or (iii) to the extent, but only to such
extent, that an intellectual property infringement claim involves any markings
or logos specifically requested by the Owner in writing.  The

                                      -40-
<PAGE>

Owner agrees that it will pay all sums, including, without limitation,
attorneys' fees, damages, losses, liabilities, expenses and other costs, which,
by final judgment or decree, or in settlement of any suit or claim to which the
Owner agrees, may be assessed against the Vendor on account of such matters,
provided that:
- - - -------- ----

            (a)  the Owner will be given prompt written notice of all claims of
      any such infringement or violation and of any suits or claims brought or
      threatened against the Vendor or the Owner of which the Vendor has actual
      knowledge;

            (b)  the Owner is given full authority to assume control of the
      defense (including appeals) thereof through its own counsel at its sole
      expense and will have the sole right to settle any suits or claims
      without the consent of the Vendor, provided that the Owner has no
                                         -------- ----
      right to agree to injunctive relief against the Vendor; provided
                                                              --------
      further that the Owner will notify the Vendor of any proposed
      -------
      settlement prior to the Owner's acceptance of such settlement; and

            (c)  the Vendor will cooperate fully with the Owner in the defense
      of such suit or claims and provide the Owner, at the Owner's expense,
      such assistance as the Owner may reasonably require in connection
      therewith, including, but not limited to, implementation of modifications
      to Products or other manufacturing fixes pursuant to the provisions of
      subsection 3.23.

      7.5  Software License.  (a)  Certain Products sold to the Owner
           ----------------
hereunder may contain software in executable code form ("Software"), and,
except as otherwise expressly provided herein, all references to "Products" in
this Agreement will be deemed to include the accompanying Software,
provided that nothing herein will be construed as the sale of any
- - - -------- ----
Software to the Owner.  The Vendor hereby grants to the Owner a non-exclusive
royalty-free world-wide license to use (for the period of time the Product is
in use in accordance with its intended use), and sublicense to the Owner's or
its Agents' Purchasers or end user customers (in object form only), the
Software solely in each of the Products purchased by the Owner from the Vendor
and for use only in the manner in which such Products are intended to be used
pursuant to the terms of this Agreement, including, without limitation, the
Specifications.

      (b)  The Owner will not, without the prior written consent of the Vendor:
(i) alter, modify, translate or adapt any Software or create any derivative
works based thereon; (ii) copy any Software; (iii) assign, sublicense or
otherwise transfer the Software in whole or in part, except as permitted
herein; (iv) use the Software except as specifically contemplated in this
Agreement; or (v) disclose the Software to any third party except as required
by Applicable Law or pursuant to an order of a court of competent jurisdiction
or other similar requirement of a Governmental Entity; provided that
                                                       -------- ----
the Owner will use reasonable efforts to provide the Vendor prior written
notice prior to any such disclosure.  The entire right, title and interest in
the Software will remain with the Vendor, and the Owner will not remove any
copyright notices or other legends from the Software or any accompanying
documentation, without the prior written consent of the Vendor.

                                      -41-
<PAGE>

      7.6  Sublicense of Software.  The Owner may sub-license to Agents,
           ----------------------
Purchasers or other end-user customers the right to use the Software in object
form only with the use of the Products resold by the Owner to such customers,
and such right will survive termination of this Agreement.

      7.7  Ownership of Intellectual Property Rights.  (a)  Except for
           -----------------------------------------
licenses expressly granted under this Agreement, the sale of Products and the
license of Software to the Owner does not convey to the Owner any intellectual
property rights in such Products or Software.  Neither the sale of Products,
the license of any Software, nor any provision of this Agreement will be
construed to grant to the Owner, either expressly, by implication or by way of
estoppel, any license under any patents or other intellectual property rights
of the Vendor covering or relating to any other product or invention of the
Vendor or any combination of Product or Software with any other product of the
Vendor.  The foregoing notwithstanding, the Parties understand and agree that
from time to time the Owner may devise, develop or otherwise create ideas or
other concepts for services or new products which are patentable or otherwise
capable of receiving protection from duplication.  In such event, the Owner
will have the right to patent or otherwise protect such ideas or concepts for
its own use and benefit.

      (b)  The Owner hereby acknowledges and agrees that nothing herein gives
it any right, title or interest in the Mark and that upon termination of this
Agreement, by expiration or termination in accordance with this Agreement, the
Owner will no longer use the Mark in advertising or in any other manner,
provided that such termination will not affect any use by the Owner's
- - - -------- ----
Agents, Purchasers or other customers of Products sold by the Owner and
provided further that nothing in this subsection 7.7 will prohibit or
- - - -------- -------
otherwise inhibit in any way the sale following such termination by the Owner
of inventory held by it at the time of such termination.  The Owner will not
challenge the validity of the Vendor's ownership of or right to use of the Mark
or the Vendor's copyrights, nor otherwise impair the interest of the Vendor in
the Mark or such copyrights.  Except as specifically provided for under this
Agreement, the Owner will not use any mark which is confusingly similar to, or
a colorable imitation of the Mark.  The Owner will use the Products and
Software furnished by the Vendor solely in accordance with the terms of this
Agreement, and the Owner will not, directly or indirectly, disassemble,
decompile, reverse engineer, or analyze or copy the physical construction of,
any of the Products or Software or any component thereof for any purpose other
than as expressly permitted by the Vendor in writing.

      7.8  Intellectual Property.  Subject to the Vendor's then existing
           ---------------------
reasonable marketing policies, if any, with respect to Products sold hereunder,
the Vendor grants the Owner rights to state that it is using the Vendor's
Products in the Owner's marketing, advertising or promotion of the Nationwide
Network, any PCS System, any part thereof or any Product.  Subject to the
Vendor's then existing reasonable marketing policies, if any, with respect to
Products sold hereunder the Owner has the right to use for such marketing,
advertising or promotion the Vendor's advertising and marketing materials
(including pamphlets and brochures) provided to the Owner by the Vendor
describing the Nationwide Network, any PCS System, any part thereof or any
Product.

                                      -42-
<PAGE>

Other than as set forth in this subsection 7.8 or subsections 3.17 or 6.2, the
Owner has the right to use the trademarks and service marks of the Vendor in
the Owner's marketing, advertising and promotion of the Nationwide Network, any
PCS System, any part thereof or any Product only with the written consent of
the Vendor, such consent not to be unreasonably withheld, subject to and in
accordance with the terms of subsection 8.1.

      7.9  Request for Custom Development.  (a)  From time to time, the
           ------------------------------
Owner may have requirements for custom Software (including, but not limited to,
development of identified features or modifications to Software or Software
Enhancements) or custom development of Products (including, but not limited to,
development of identified features or modifications to Products or Product
Enhancements) to be provided by the Vendor under this Agreement (the "Custom
Material").  If the Owner has a requirement for Custom Material that is a
specific enhancement or modification of a previously licensed feature or of
previously purchased Products, the Owner will identify to the Vendor in writing
a summary of any such proposed development of Custom Material.  Such summary
will provide a description of any proposed Custom Material sufficient to enable
the Vendor to determine the general demand for, and its plans, if any, to
develop the same or similar Products.  The Vendor will respond to such summary
within thirty (30) days after receipt thereof and indicate if it has the
ability to fulfill a subsequent Request for Proposal ("RFP") from the Owner for
such development of Custom Material.  The Owner acknowledges that the Vendor
shall have no obligation to develop any proprietary materials for Owner other
than as expressly set forth in this subsection 7.9.

      (b)  If the Vendor decides that it does not have the technical ability or
the capacity to fulfill a RFP for such Custom Material development, the
Vendor's response pursuant to subsection 7.9(a) will (i) provide the Owner an
explanation of why it cannot fulfill such RFP and (ii) use reasonable diligence
to work with the Owner to identify an alternative source for such development
reasonably acceptable to the Owner.  In determining whether the Vendor has the
technical ability or the capacity to fulfill the RFP, the Vendor may consider
factors including, but not limited to, (i) the Vendor's likelihood of
recovering the costs for performing such development, (ii) the impact of such
development on the Vendor's actual outstanding commitments to perform work for
other Customers and to pursue strategic development activities; and (iii)
whether the Vendor can perform the work utilizing existing software development
staff without stopping work underway.

      7.10  Vendor Response.  After reviewing an RFP issued to the Vendor
            ---------------
from the Owner for such Custom Material, the Vendor will respond to the Owner
within thirty (30) days, unless otherwise agreed by the Parties, stating the
terms and conditions upon which the Vendor would be willing to undertake such
development, including, but not limited to, a listing of specifications, custom
development charges, planned license fees and a proposed delivery schedule.

      SECTION 8.  PROPRIETARY INFORMATION

      8.1  Public Statements and Advertising.  (a)  Except to the extent
           ---------------------------------
specifically set forth herein, the Vendor will not issue any public statement
(or any private statement unless required in the performance of the work
contemplated by this Agreement) relating to or in any way disclosing any aspect
of the work contemplated by this Agreement, the Nationwide Network, any Owner
PCS System or any Product (other than statements regarding the Vendor's
products generally) including the scope, the specific terms of this Agreement,
extent or value of the work contemplated by this Agreement, the Products (other
than statements regarding the Vendor's products generally) and/or the
Nationwide Network or any Owner PCS System.  The Owner will not issue any
public statement (or any private statement unless required in the performance
of the work contemplated by this Agreement) relating to or in any way
disclosing any aspect of the work contemplated by this Agreement or any Product
(other than statements regarding the Vendor's products generally), including
the scope, the specific terms of this Agreement, the extent or value of the
work contemplated by this Agreement and/or the Products (other than statements
regarding the Vendor's products generally).  The Vendor agrees not to use for
publicity purposes any photographs, drawings and/or materials describing any
PCS System or any part of the Nationwide Network (other than Vendor Products),
without obtaining the prior written consent of the Owner, such consent not to
be unreasonably withheld.  The obligations of the Parties under this subsection
8.1 are in addition to their respective obligations pursuant to subsection 8.2
but in no way limit the exceptions to public disclosure specifically referred
to in subsection 8.2(a) clauses (i) through (vii).  This subsection 8.1 will in
no way limit (i) either Party from responding to customary press inquiries or
otherwise making public or private statements not otherwise disclosing
Proprietary Information or the specific terms of this Agreement in the normal
course of its business and/or in connection with the obligations hereunder or
(ii) the provision of necessary information to prospective suppliers and the
Vendor's or the Owner's personnel, agents or consultants.

      (b)  Each Party will submit to the other proposed copies of all
advertising (other than public statements or press releases pursuant to and in
accordance with the last sentence of subsection 8.1(a) above) wherein the name,
trademark or service mark of the other Party or its Affiliates or affiliates is
mentioned; and neither Party will publish or use such advertising without the
other Party's prior written approval.  Such approval will be granted as
promptly as possible and will not be unreasonably withheld.  The Parties
acknowledge that the obtaining of prior written approval for each such use
pursuant to this subsection 8.1(b) may be an administrative burden.  From time
to time at the request of either Party, the Owner and the Vendor will establish
mutually acceptable guidelines that will constitute pre-authorization for the
uses specified therein.  Such guidelines will be subject to change from time to
time at the reasonable request of either Party subject to the mutual agreement
of the Parties.

      8.2  Confidentiality.  (a)  All information, including without
           ---------------
limitation all oral and written information (including, but not limited to,
determinations or reports by arbitrators pursuant to the terms of this
Agreement), disclosed to the other Party is

                                      -44-
<PAGE>

deemed to be confidential, restricted and proprietary to the disclosing Party
(hereinafter referred to as "Proprietary Information").  Each Party agrees to
use the Proprietary Information received from the other Party only for the
purpose of this Agreement.  Except as specified in this Agreement, no other
rights, and particularly licenses, to trademarks, inventions, copyrights,
patents, or any other intellectual property rights are implied or granted under
this Agreement or by the conveying of Proprietary Information between the
Parties.  Proprietary Information supplied is not to be reproduced in any form
except as required to accomplish the intent of, and in accordance with the
terms of, this Agreement.  The receiving Party must provide the same care to
avoid disclosure or unauthorized use of Proprietary Information as it provides
to protect its own similar proprietary information but in no event will the
receiving Party fail to use reasonable care under the circumstances to avoid
disclosure or unauthorized use of Proprietary Information.  All Proprietary
Information must be retained by the receiving Party in a secure place with
access limited to only such of the receiving Party's employees, subcontractors,
suppliers or agents who need to know such information for purposes of this
Agreement and to such third parties as the disclosing Party has consented to by
prior written approval.  All Proprietary Information, unless otherwise
specified in writing (i) remains the property of the disclosing Party, (ii)
must be used by the receiving Party only for the purpose for which it was
intended, and (iii) such Proprietary Information, including all copies of such
information, must be returned to the disclosing Party or destroyed after the
receiving Party's need for it has expired or upon request of the disclosing
Party, and, in any event, upon termination of this Agreement.  At the request
of the disclosing Party, the receiving Party will furnish a certificate of an
officer of the receiving Party certifying that Proprietary Information not
returned to the disclosing Party has been destroyed.  For the purposes hereof,
Proprietary Information does not include information that:

            (i)   is published or is otherwise in the public domain through no
                  fault of the receiving Party at the time of any claimed
                  disclosure or unauthorized use by the receiving Party;

            (ii)  prior to disclosure pursuant to this Agreement is properly
                  within the legitimate possession of the receiving Party as
                  evidenced by reasonable documentation to the extent
                  applicable;

            (iii) subsequent to disclosure pursuant to this Agreement is
                  lawfully received from a third party having rights in the
                  information without restriction of the third party's right to
                  disseminate the information and without notice of any
                  restriction against its further disclosure;

            (iv)  is independently developed by the receiving Party or is
                  otherwise received through parties who have not had, either
                  directly or indirectly, access to or knowledge of such
                  Proprietary Information;

            (v)   is transmitted to the receiving Party after the disclosing
                  Party has received written notice from the receiving Party,
                  after termination

                                      -45-
<PAGE>

                  or expiration of this Agreement, that it does not desire to
                  receive further Proprietary Information;

            (vi)  is obligated to be produced under order of a court of
                  competent jurisdiction or other similar requirement of a
                  Governmental Entity, so long as the Party required to
                  disclose the information provides the other Party with prior
                  notice of such order or requirement and its cooperation to
                  the extent reasonable in preserving its confidentiality; or

            (vii) the disclosing Party agrees in writing is free of such
                  restrictions.

      (b)  Because damages may be difficult to ascertain, the Parties agree
that, without limiting any other rights and remedies specified herein, an
injunction may be sought against the Party who has breached or threatened to
breach this subsection 8.2.  Each Party represents and warrants that it has the
right to disclose all Proprietary Information which it has disclosed to the
other Party pursuant to this Agreement, and each Party agrees to indemnify and
hold harmless the other from all claims by a third party related to the
wrongful disclosure of such third party's proprietary information.  Otherwise,
neither Party makes any representation or warranty, express or implied, with
respect to any Proprietary Information.

      SECTION 9.  INDEMNIFICATION/LIMITATION OF LIABILITY

      9.1  Vendor Indemnity.  (a)  The Vendor will indemnify and hold the
           ----------------
Owner and its affiliates, partners, directors, officers, agents and employees
(the "Indemnitees") harmless from and against all third party claims, demands,
suits, proceedings, damages, costs, expenses, liabilities, including, without
limitation, reasonable legal fees (collectively, "Liabilities") brought against
or incurred by any Indemnitee for (i) injury to persons (including physical or
mental injury, libel, slander and death), or (ii) loss or damage to any
property, or (iii) any other liability, in each instance resulting from the
negligence, willful misconduct or gross negligence, of the Vendor in the
performance of this Agreement.  If the Vendor and the Owner jointly cause such
Liabilities, the Parties will share the liability in proportion to their
respective degree of causal responsibility.

      (b)  The Vendor's obligation to indemnify under subsection 9.1(a) with
respect to any Liability will not arise unless the Indemnitee (i) notifies the
Vendor in writing of such potential Liability within a reasonable time after
the Indemnitee is aware of such potential Liability; provided that the
                                                     -------- ----
lack of providing such notice will not affect the Vendor's obligation hereunder
(A) if the Vendor otherwise has actual knowledge of such Liability and (B)
unless such lack of notice is the cause of the Vendor being unable to
adequately and reasonably defend such Liability, (ii) gives the Vendor the
opportunity and authority to assume the defense of and settle such Liability,
subject to the provisions of the next two sentences, and (iii) furnishes to the
Vendor all such reasonable information and assistance available to the Owner
(or other Indemnities) as may be reasonably requested by the Vendor and
necessary for the defense against such Liability.

                                      -46-
<PAGE>

The Vendor will assume on behalf of the Indemnitee and conduct in good faith
the defense of such Liability with counsel (including in-house counsel)
reasonably satisfactory to the Indemnitee; provided that the Indemnitee
                                           -------- ----
will have the right to be represented therein by advisory counsel of its own
selection and at its own expense.  If the Indemnitee will have reasonably
concluded that there may be legal defenses available to it which are different
from or additional to, or inconsistent with, those available to the Vendor, the
Indemnitee will have the right to select separate counsel reasonably
satisfactory to the Vendor to participate in the defense of such action on its
own behalf at such Indemnitee's expense.  In the event the Vendor fails, after
written demand by such Indemnitee, to defend any Liability as to which an
indemnity should be provided under subsection 9.1(a), then the Indemnitee may,
at the Vendor's expense, contest or settle such matter without the Vendor's
consent.  All payments, losses, damages and reasonable costs and expenses
incurred in connection with such contest, payment or settlement controlled by
such Indemnitee will be to the Vendor's account.  The Vendor will not settle
any such Liability without the consent of the Indemnitee, which consent will
not be unreasonably withheld.  Any such Indemnitee will exercise its best
efforts to respond to any request for a consent prior to the expiration of any
such settlement offer.  This indemnity is in lieu of all other obligations of
the Vendor, expressed or implied, in law or in equity, to indemnify the
Indemnitees (except those other indemnity obligations expressly set forth in
this Agreement).

      (c)  EXCEPT AS EXPRESSLY SET FORTH IN SUBSECTIONS 3.7 AND 3.8 OF THIS

      9.2  Vendor Damages for Fraud.  The Vendor will be responsible for
           ------------------------
all actual damages incurred by the Owner as a result of any damage or injury
caused by or resulting from the fraud of the Vendor; provided, however,
                                                     --------  -------
if the senior management of the Vendor knew or should have known of such fraud,
then the Vendor will be responsible for all damages (including, but not limited
to, actual, consequential, incidental and special) so incurred by the Owner for
such fraud.

      9.3  Owner Indemnity.  (a)  The Owner will indemnify and hold the
           ---------------
Vendor and its affiliates, partners, directors, officers, agents and employees
(the "Vendor Indemnitees") harmless from and against all third party claims,
demands, suits, proceedings, damages, costs, expenses, liabilities, including,
without limitation, reasonable legal fees (collectively, "Vendor Liabilities")
brought against or incurred by any Vendor Indemnitee for (i) injury to persons
(including physical or mental injury, libel, slander and death), or (ii) loss
or damage to any property, or (iii) any other liability, in each instance
resulting from the negligence, willful misconduct or gross negligence, of the
Owner in the performance of this Agreement.  If the Vendor and the Owner
jointly cause such Vendor Liabilities, the Parties will share the liability in
proportion to their respective degree of causal responsibility.

      (b)  The Owner's obligation to indemnify under subsection 9.3(a) with
respect to any Vendor Liability will not arise unless the Vendor Indemnitee (i)
notifies the Owner in writing of such potential Vendor Liability within a
reasonable time after the Vendor Indemnitee is aware of such potential Vendor
Liability; provided that the lack of providing such notice will not
           -------- ----
affect the Owner's obligation hereunder (A) if the Owner otherwise has actual
knowledge of such Vendor Liability and (B) unless such lack of notice is the
cause of the Owner being unable to adequately and reasonably defend such Vendor
Liability, (ii) gives the Owner the opportunity and authority to assume the
defense of and settle such Vendor Liability, subject to the provisions of the
next two sentences, and (iii) furnishes to the Owner all such reasonable
information and assistance available to the Vendor (or other Vendor
Indemnitees) as may be reasonably requested by the Owner and necessary for the
defense against such Vendor Liability.  The Owner will assume on behalf of the
Vendor Indemnitee and conduct in good faith the defense of such Liability with
counsel (including in-house counsel) reasonably satisfactory to the Vendor
Indemnitee; provided that the Vendor Indemnitee will have
            -------- ----
                                      -49-
<PAGE>

the right to be represented therein by advisory counsel of its own selection
and at its own expense.  If the Vendor Indemnitee will have reasonably
concluded that there may be legal defenses available to it which are different
from or additional to, or inconsistent with, those available to the Owner, the
Vendor Indemnitee will have the right to select separate counsel reasonably
satisfactory to the Owner to participate in the defense of such action on its
own behalf at such Vendor Indemnitee's expense.  In the event the Owner fails,
after written demand by such Vendor Indemnitee, to defend any Vendor Liability
as to which an indemnity should be provided under subsection 9.3(a), then the
Vendor Indemnitee may, at the Owner's expense, contest or settle such matter
without the Owner's consent.  All payments, losses, damages and reasonable
costs and expenses incurred in connection with such contest, payment or
settlement controlled by such Vendor Indemnitee will be to the Owner's account.
The Owner will not settle any such Vendor Liability without the consent of the
Vendor Indemnitee, which consent will not be unreasonably withheld.
Furthermore, the Owner will indemnify and hold the Vendor Indemnitees harmless
from and against all Vendor Liabilities brought against or incurred by any
Vendor Indemnitee for (i) injury to persons (including physical or mental
injury, libel, slander and death), or (ii) loss or damage to any property, or
(iii) any other liability resulting directly and solely from the unauthorized
modification by the Owner of the Products or by the Owner's use of any Product
in combination with any other Subscriber Unit accessory not furnished and/or
authorized in writing for such use by the Vendor.  This indemnity is in lieu of
all other obligations of the Owner, expressed or implied, in law or in equity,
to indemnify the Vendor Indemnitees (except those other indemnity obligations
expressly set forth in this Agreement).

      9.4  Owner Damages for Fraud.  The Owner will be responsible for
           -----------------------
actual damages incurred by the Vendor as a result of any damage or injury
caused by or resulting from the fraud of the Owner; provided, however,
                                                    --------  -------
if the senior management of the Owner knew or should have known of such fraud,
then the Owner will be responsible for all damages (including, but not limited
to, actual, consequential, incidental and special) so incurred by the Vendor
for such fraud.

      SECTION 10.  TERMINATION

      10.1  Termination.  This Agreement will terminate on the End Date,
            -----------
unless extended by mutual agreement of the Parties hereto, in accordance with
Section 2, or unless sooner terminated as provided herein.  Any such
termination in accordance with the terms of this Section 10 will in no way
terminate, modify, amend or otherwise affect the Vendor's warranties hereunder
(or the enforceability thereof) in connection with Products sold pursuant to
the terms of this Agreement.

      10.2  Termination For Cause.  The Owner has the right to terminate
            ---------------------
this Agreement in its entirety without any penalty or payment obligation upon
the occurrence of any Vendor event of default (each a "Vendor Event of
Default") as set forth below.  The occurrence of any of the following will
constitute a Vendor Event of Default:

                                      -50-
<PAGE>

      (a)  the Vendor (i) files a voluntary petition in bankruptcy or has an
involuntary petition in bankruptcy filed against it that is not dismissed
within sixty (60) days of such involuntary filing, (ii) admits the material
allegations of any petition in bankruptcy filed against it, (iii) is adjudged
bankrupt, or (iv) makes a general assignment for the benefit of its creditors,
or if a receiver is appointed for all or a substantial portion of its assets
and is not discharged within sixty (60) days after his appointment; or

      (b)  the Vendor commences any proceeding for relief from its creditors in
any court under any state insolvency statutes; or

      (c) the Vendor violates any Applicable Law and the effect of such
violation materially impairs the Vendor's ability to perform its obligation
under this Agreement; or

      (d)  the Vendor fails to perform this Agreement in any material respect
and thereby prejudices in any way deemed material by the parties providing
financing in connection with the build-out of the Nationwide Network, in such
parties' reasonable opinion, the Owner's efforts to obtain financing for the
Nationwide Network; or

      (e)  the Vendor fails to comply with subsection 11.18; or

      (f)  the Vendor breaches any other provision of this Agreement and the
effect of such breach materially impairs the Vendor's ability to perform its
obligations under this Agreement.

      10.3  Remedies.  If any of the Vendor Events of Default exists, the
            --------
Owner may, without prejudice to any other rights or remedies of the Owner in
this Agreement or at law or in equity (except as such legal or equitable
remedies may be limited by this Agreement), terminate this Agreement upon
written notice to the Vendor; provided, however, that the Owner will
                              --------  -------
have first provided to the Vendor the following periods of notice and
opportunity to cure:

             (i)  in the case of an Event of Default specified in subsections
      10.2(a) and 10.2(b), no notice or opportunity to cure will be required
      from the Owner; and

            (ii)  in the case of any other Event of Default by the Vendor, the
      Owner will have provided thirty (30) days' prior written notice, and the
      Vendor will have failed to diligently pursue such cure and remedy the
      breach entirely by the end of said thirty (30) day notice period.

      10.4  Discontinuance of Supply.  Upon such notification of
            ------------------------
termination, the Vendor must immediately discontinue all supply of Products.

      10.5  Payments.  When the Owner terminates this Agreement for cause
            --------
pursuant to subsection 10.2, notwithstanding anything herein to the contrary,
the Owner may

                                      -51-
<PAGE>

withhold payments in amounts that it reasonably believes are in dispute, if
any, at such time to the Vendor for the purposes of offset of amounts owed to
the Owner pursuant to the terms of this Agreement, until such time as the exact
amount of damages due to the Owner from the Vendor is fully determined;
provided that in the event that any such disputed amounts are
         ----
determined to in fact be owed by the Owner to the Vendor, such amounts will be
increased by the late payment penalties, if any, applicable thereto pursuant to
subsection 3.4.

      10.6  Costs.  In the event of a termination due to a Vendor Event of
            -----
Default, the Owner will be entitled to receive from the Vendor the following:
(i) with respect to those costs and expenses incurred by the Owner in procuring
substitute subscriber units (and their included accessories) for the Products
not delivered by the Vendor, only those reasonable direct out of pocket costs
and expenses incurred by the Owner in reasonably procuring substitute
subscriber units (and their included accessories) having the most comparable
features and functionality available at such time, in excess of the costs and
expenses the Owner would have otherwise incurred hereunder in purchasing such
undelivered Products; and (ii) with respect to any other costs and expenses
incurred by the Owner, only those reasonable direct out-of-pocket costs and
expenses incurred by the Owner that the Owner would not otherwise have incurred
under this Agreement which arise as a result of the Vendor's failure to perform
any other obligation under this Agreement.  For the purpose of clause "(i)" of
this subsection 10.6, the Owner shall be entitled to recover only those
reasonable direct out of pocket costs and expenses pertaining to procuring that
number of substitute subscriber units (and their included accessories) equal to
(x) the amount of the Total Minimum Commitment (as such amount may be increased
or decreased from time to time pursuant to the terms of this Agreement), minus
(y) that number of Subscriber Units purchased by the Owner as of the date of
any such termination.  The amount to be paid by the Vendor pursuant to this
subsection 10.6 will survive termination of this Agreement and will be subject
to the limitations of liability set forth in this Agreement.

      10.7  Continuing Obligations.  Termination of this Agreement for any
            ----------------------
reason (i) will not relieve either Party of its obligations with respect to the
confidentiality of the Proprietary Information as set forth in subsection 8.2,
(ii) will not relieve either Party of any obligation which applies to it and
which expressly or by implication survives termination, and (iii) except as
otherwise provided in any provision of this Agreement expressly limiting the
liability of either Party, will not relieve either Party of any obligations or
liabilities for loss or damage to the other Party arising out of or caused by
acts or omissions of such Party prior to the effectiveness of such termination.

      10.8  The Vendor's Right to Terminate.  The Vendor has the right to
            -------------------------------
terminate this Agreement in its entirety without any penalty or payment
obligations, upon the occurrence of any of the following (each an "Owner Event
of Default"):

      (a)  the Owner (i) files a voluntary petition in bankruptcy or has an
involuntary petition in bankruptcy filed against it that is not dismissed
within sixty (60) days of such involuntary filing, (ii) admits the material

<PAGE>

against it, (iii) is adjudged bankrupt, or (iv) makes a general assignment for
the benefit of its creditors, or if a receiver is appointed for all or a
substantial portion of its assets and is not discharged within sixty (60) days
after his appointment; or

      (b)  the Owner commences any proceeding for relief from its creditors in
any court under any state insolvency statutes; or

      (c)  the Owner fails to (i) make payments of undisputed amounts

provided that such failure has continued for at least fifteen (15) days
- - - -------- ----
after the Vendor has provided the Owner with written notice of its intent to so
terminate on account of such overdue amount, or (ii) make payments of
undisputed amounts in excess of five million ($5,000,000) due to the Vendor
pursuant to the terms of this Agreement, provided that such failure has
                                         -------- ----
continued for at least thirty (30) days after the Vendor has provided the Owner
with written notice of its intent to so terminate on account of such overdue
amount; and provided further that if the Vendor notice provided to the
            -------- -------
Owner pursuant to and in accordance with either clause (i) or (ii) is the first
such notice provided to the Owner by the Vendor in any rolling twelve (12)
month period, the Owner will have an additional thirty (30) days to cure any
such default prior to the Vendor having the right to terminate this Agreement
pursuant to this subsection 10.8(c); or

      (d)  the Owner repeatedly and materially breaches subsection 8.2
notwithstanding the fact that the Vendor will have provided the Owner with
prior written notice describing the alleged material breaches and will have
given the Owner a reasonable time (not less than thirty (30) days) to cure any
such breaches; or

      (e)  the Owner fails to comply with subsection 11.19; or

      (f)  the Owner violates any Applicable Laws, and the effect of such
violation materially impairs the Owner's ability to perform its obligations
under this Agreement; or

      (g)  the Owner fails to purchase in any of the respective Annual Supply

with the terms of this Agreement; or

      (h)  the Owner fails to issue Purchase Orders for those amounts of
Products which are considered to be under firm Purchase Orders pursuant to any
Forecast and in accordance with the terms of this Agreement; or

            ---------------
the Vendor may, without prejudice to any rights or remedies of the Vendor in
this Agreement or at law or in equity (except as such legal or equitable

this Agreement, immediately upon the occurrence of any Owner Event of Default
the Vendor shall have the right, without any penalty or payment obligations, to
suspend Vendor's performance with respect to manufacturing Products, to stop
shipment of all Products subject to Purchase Orders, and to recall, if
possible, all Products subject to unfulfilled or undelivered Purchase Orders.

      10.10  Special Termination Events.  (a) In the event that financing
             --------------------------
for the Owner's build-out of the initial phase of the Nationwide Network has
not been finalized with the Contract Vendors on terms and conditions reasonably
satisfactory to the Owner, on or before July 29, 1996, the Owner will have the
right, but not the obligation, to terminate this Agreement in its entirety
without charge or penalty of any kind; provided that the Owner will
                                       -------- ----
only have this right if it has terminated or materially amended (as a result of
a failure to achieve adequate financing) at least one of its then existing
Procurement and Services Contracts; and provided further that in the
                                        -------- -------
event the Owner elects to exercise its rights under this subsection 10.10 and
any Procurement and Services Contract then remains outstanding and in force,
the Vendor and the Owner will negotiate in good faith to make any equitable
modifications in Annual Minimum Commitments and corresponding pricing prior to
and in lieu of any such termination.  The "Financing Interim Period" means the
period from the Effective Date to July 29, 1996.  In the event of a termination
of this Agreement pursuant to this subsection 10.10, the Owner will remain
liable for amounts due to the Vendor for (i) amounts owed by the Owner to the
Vendor prior to such termination, (ii) all Products which are forecasted in the
first five months of the then current Forecast Period for the then current
Forecast (up to the full amount of such forecasted Products) which are
delivered by the Vendor pursuant to the specific terms of this Agreement to the
FOB point, the Owner and/or any of its facilities or sites in accordance with
the terms of this Agreement and (iii) all such other amounts for customization,
specific engineering or change orders ordered by the Owner prior to such
termination.  Any amounts owed by the Owner for Products delivered by the
Vendor during such Financing Interim Period not otherwise invoiced to the Owner
by the Vendor prior to the termination of such Financing Interim

                                      -54-
<PAGE>

Period, will be invoiced to the Owner by the Vendor within thirty (30) days
(but failure to so invoice will not excuse the Owner's obligation to otherwise
pay the Vendor pursuant to the terms of this subsection 10.10) of such
termination pursuant to this subsection 10.10 and will be payable by the Owner
within thirty (30) days of receipt of such invoice.  Except as specifically set
forth in clause (i), clause (ii) and/or clause (iii) above, in this subsection
10.10, in no event will the Owner be liable to the Vendor due to a termination
of this Agreement pursuant to this subsection 10.10 for any of the Vendor's
direct or indirect costs or expenses incurred in connection with any supplies
or equipment ordered by the Vendor or agreements entered into by the Vendor in
order to enable it to fulfill its obligations hereunder or in connection with
the establishment of and/or upgrade to its manufacturing, personnel,
engineering, administrative or other capacities and/or resources in
contemplation of or pursuant to its performance in accordance with the terms of
this Agreement.

      (b) If, prior to May 2, 1997 the Vendor, for any reason whatsoever, fails
or is otherwise unable to commence delivery to the Owner of Subscriber Units
with an average of four (4) hours of continuous talk time based on thirty five
percent (35%) voice activity, ten (10) dBm transmit power at the antenna,and a
standard battery pack, the Owner will be able to, in its sole discretion, on
May 2, 1997 or at any time within the ten (10) Business Day period thereafter,
terminate this Agreement in its entirety without any payment or penalty of
either Party whatsoever; provided that within
                                                           -------- ----
thirty (30) days of such termination each Party will pay any and all monies then
actually outstanding, owed, accrued or otherwise due to the other Party up to
the point of such termination including payment for any Purchase Orders or
Excess Purchase Orders from the Owner to the Vendor outstanding at the time of
such termination; and provided further the Owner will still be committed to
                      -------- -------
submit Purchase Orders and pay for all Products delivered subject to the most
recent then outstanding Forecasts for May, June and July 1997 pursuant to the
terms of this Agreement.

      SECTION 11.  GENERAL PROVISIONS

      11.1  Assignment.  Except as otherwise permitted herein, neither this
            ----------
Agreement nor any portion hereof may be assigned by either Party without the
express prior written consent of the other Party provided that such
                                                 -------- ----
consent will not otherwise be unreasonably withheld.  The Owner may, without
the consent of the Vendor, (i) assign in whole, but not in part, its rights
hereunder to any direct or indirect wholly owned operating subsidiary of the
Owner or of Sprint Spectrum Holding Company, L.P., a Delaware limited
partnership (provided that any such assignment to any such subsidiary
             -------- ----
will not be deemed a release of the Owner's obligations hereunder unless the
Vendor will have given prior written consent to any such release) and/or (ii)
collaterally assign its rights hereunder (including, but not limited to, all
licenses with respect to the Software) to the parties providing financing for
any part of the Nationwide Network under a collateral trust for the benefit of
the Vendor and one or more other entities providing financing for any part of
the Nationwide Network or similar arrangement for the benefit of the entities
providing for the financing for any part of the Nationwide Network, in either
case, which collateral trust or similar arrangement, as the case may be, is
reasonably

                                      -55-
<PAGE>

condition hereof, any of the work to be performed hereunder or in connection

other time period mutually agreed to by the Parties, after such controversy,
claim, dispute, difference or misunderstanding arises.  If the Parties are
unable to resolve the controversy, claim, dispute, difference or
misunderstanding through good faith negotiations within such ten (10) Business
Day period, each Party will, within five (5) Business Days after the expiration
of such ten (10) Business Day period, prepare a written position statement

claim, dispute, difference or misunderstanding, either Party may initiate
arbitration in accordance with the provisions of subsection 11.9; provided,
                                                                  --------

of money) arising out of or relating to this Agreement by which either Party
seeks to obtain from the other monetary damages in excess of one million dollars
($1,000,000), either Party, in such case, may commence an action in any state or
federal court in accordance
with subsection 11.12 to resolve such matter in lieu of proceeding with an
arbitration pursuant to and in accordance with subsection 11.9. The arbitrators
hired or otherwise chosen pursuant to and in accordance with the terms of this
Agreement will determine issues of arbitrability pursuant to the terms of this
Agreement but may not in any way limit, expand or otherwise modify the terms of
this Agreement nor will they have any authority to award punitive or other
damages in excess of compensatory damages (other than as specifically set forth
in this Agreement) and each Party irrevocably waives any such claim thereto when
invoking the arbitration provisions of subsection 11.9.

      11.9  Arbitration.  (a)  An arbitration proceeding initiated by
            -----------
either Party under this Agreement with respect to any controversy, claim,
dispute, difference or misunderstanding will be conducted in New York in

the request of either Party, a stenographic

                                      -58-
<PAGE>

transcript of the testimony and proceedings will be taken and the arbitrators
will base their decision upon the records and briefs of the Parties.

      (b)  Such arbitration will be initiated by either Party by notifying the
other Party in writing and will be settled before three (3) impartial
arbitrators, one of whom will be named by the Owner, one by the Vendor and the
third by the two arbitrators appointed by the Owner and the Vendor,
respectively.  All of the named arbitrators will have significant experience in
the wireless telecommunications industry.  If either the Owner or the Vendor
fails to select an arbitrator within ten (10) days after notice has been given
of the initiation of the arbitration, the officer in charge of the New York
office of the AAA will have the right to appoint the other arbitrator, and the
two arbitrators thus chosen will then select the third arbitrator.

      (c)  Except as the Parties may otherwise mutually agree, the arbitration
hearings will commence within fifteen (15) Business Days after a Party's
initiation of the arbitration.  The Federal Rules of Evidence will apply and
reasonable discovery, including depositions, will be permitted.  Discovery
issues will be decided by the arbitrators and post-hearing briefs will be
permitted.

      (d)  The arbitrator will render a decision within ten (10) days after the
conclusion of the hearing(s) and submission of post-hearing briefs and a
written opinion setting forth findings of fact and conclusions of law will be
made available to the Parties within that time period.  The decision of the
majority of the arbitrators regarding the matter submitted will be final and
binding upon the Parties.  Judgment upon the award rendered by the arbitrators
may be entered in any court having jurisdiction thereof.

      (e)  Each Party will pay for the services and expenses of the arbitrator
appointed by it, its witnesses and attorneys, and all other costs incurred in
connection with the arbitration (including, without limitation, the cost of the
services and expenses of the arbitrator appointed by the two arbitrators
appointed by the Parties) will be paid in equal part by the Parties, unless the
award will specify a different division of the costs.  Unless otherwise
specifically stated in this Agreement, during the pendency of any arbitration
proceedings, the Parties agree to continue to perform their obligations
hereunder in the same manner as prior to the institution of arbitration
proceedings.

      11.10  Other Remedies.  Notwithstanding anything to the contrary
             --------------
herein contained, each Party will be entitled to pursue any equitable rights
and remedies that are available at law or in equity without complying with
subsection 11.9.

      11.11  Tolling.  All applicable statutes of limitation will be tolled
             -------
to the extent permitted by Applicable Law while the dispute resolution
procedures specified in subsections 11.8 and 11.9 are pending, and nothing
herein will be deemed to bar any Party from taking such action as the Party may
reasonably deem to be required to effectuate such tolling.

Vendor, as the case may be, at the addresses indicated in subsection 11.7
hereof and in the manner set forth in such subsection 11.7.  Nothing in this
subsection 11.12 will affect the right of the Owner or the Vendor to serve
legal process in any other manner permitted by law.

      11.13  Entire Agreement.  This Agreement, together with all
             ----------------
Appendices, Exhibits and Schedules attached hereto, which are incorporated
herein by this reference, constitutes the entire agreement between the Parties

the Parties with respect to the subject matter hereof.  No modification,
variation or amendment to this Agreement will be effective unless made in

             ----------------------------------------
improvements, inventions, and innovations made by the Owner will vest in the

incorporated herein, such conflict or inconsistency will be resolved by giving

Appendices.

             -----------------------
and the Owner pursuant to this Agreement is that of independent contractors.

<PAGE>

employer or employee, and have no other relationship pursuant to this Agreement
other than independent contracting parties.

      11.17  Force Majeure.  If the performance of this Agreement
             -------------
(including without limitation any deliveries hereunder) is interfered with by
reason of any circumstance beyond the reasonable control of the Party affected,
including without limitation, fire, acts of God or the public enemy, riots and
insurrections, strikes, boycotts or lockouts, embargoes, judicial action, lack
of or inability to obtain export permits or approvals, necessary labor,
materials, energy, components or machinery, and acts of civil or military
authorities (each an event of "Force Majeure"), then the Party affected will be
excused from such performance on a day-for-day basis to the extent of such
interference (and the other Party will likewise be excused from performance on
a day-for-day basis to the extent such Party's obligations relate to the
performance so interfered with); provided that the Party so affected
                                 -------- ----

obligation, to terminate this Agreement.  The Vendor will not be liable to the
Owner for any damages or other amounts as a result of any termination pursuant
to this subsection 11.17.  Notwithstanding anything in this subsection 11.17 to
the contrary, from the Effective Date until July 1, 1997, neither Party will be
entitled to claim an event of Force Majeure pursuant to this subsection 11.17
or otherwise, due to or based upon lack or inability to obtain export permits
or approvals, or lack of necessary labor, materials, energy, components or
machinery, unless such lack or inability to obtain export permits or approvals,
lack of necessary labor, materials, energy, components or machinery is due to a
verifiable force majeure claim from a third party supplier (to the Owner or the
Vendor, as the case may be) based upon a fire, act of God or public enemy, riot
or insurrection, strike, boycott or lockout, embargo, judicial action, and/or
acts of civil or military authorities that is beyond the reasonable control of

of the value of the Owner's limited partnership interests or general
partnership interests where such Person or group did not own as of the
Effective Date in excess of ten percent (10%) of either of such partnership
interests (any such Person or group will be referred to as the "Owner's
Succeeding Entity"), unless:

      (a)  the Owner's Succeeding Entity will agree to assume the obligations
of the Owner under this Agreement; and

      (b)  the Vendor will have approved the transaction, based solely on (i)

      SECTION 14.  GUARANTY

        14.1  Guaranty.  Each of the Guarantors hereby irrevocably and
              ---------
unconditionally, severally but not jointly, guarantees the punctual payment and
performance of each and every obligation of the Vendor under this Agreement
and agrees that if for any reason whatsoever the Vendor will fail or be unable
duly, punctually and fully to perform any such obligation under this Agreement,
either of the Guarantors will forthwith perform each and every such obligation,
or cause each such obligation to be performed, without regard to any exercise
or nonexercise by the Owner of any right, remedy, power or privilege under or
in respect of the Agreement against the Vendor.  The obligations of each of the
Guarantors will be subject to the Owner providing each of the Guarantors
written notice (unless the giving of such notice is prevented by Applicable Law
or court order) of any default of the Vendor in performing any obligation for
which the Owner is seeking the guaranty of either Guarantor.  The Guarantors
will cure such default within fifteen (15) Business Days after receipt by the
Guarantors of written notice thereof specifying the nature of such default.  In
addition, the Guarantors agree to reimburse the Owner on demand for any and all
expenses (including counsel fees and expenses) reasonably incurred by the Owner
in enforcing or attempting to enforce any rights under this guaranty.
Notwithstanding anything to the contrary stated in this Section 14, QUALCOMM
will only be liable for up to fifty one percent (51%) of the obligations under
this Section 14, including, but not limited, to all payment obligations under
this Section 14 and Sony will only be liable for up to forty

                                      -66-
<PAGE>

nine percent (49%) of the obligations under this Section 14, including, but not
limited to, all payment obligations under this Section 14.

            14.2  Guaranty Absolute.  The liability of each of the
                  -----------------
Guarantors under this Guaranty with respect to the guaranteed obligations will
be absolute and unconditional, irrespective of:

      (a)   any lack of validity or enforceability of this Agreement or any
            other agreement or instrument relating thereto;

      (b)   any amendment to, waiver of or consent to departure from, or
            failure to exercise any right, remedy, power or privilege under or
            in respect of, this Agreement, unless the Owner, and any assignee
            of Owner pursuant to Subsection 11.1, shall expressly agree
            otherwise in writing, and then only to the extent that such
            liability is released in such written agreement;

      (c)   any exchange, release or nonperfection of any collateral, or any
            release or amendment or waiver of or consent to departure from any
            other guaranty of or security for the performance of all or any of
            the obligations of the Vendor under the Agreement;

      (d)   the insolvency of the Vendor or any other guarantor or any
            proceeding, voluntary or involuntary, involving the bankruptcy,
            insolvency, receivership, reorganization, arrangement, dissolution
            or liquidation of the Vendor or any other guarantor or any defense
            which the Vendor or any other guarantor may have by reason of the
            order, decree or decision of any court or administrative body
            resulting from any such proceeding;

      (e)   any change in ownership of the Vendor or any change, whether direct
            or indirect, in the relationship of either of the Guarantors to the
            Vendor, including, without limitation, any such change by reason of
            any merger or any sale, transfer, issuance, or other disposition of
            any stock of the Vendor, each of the Guarantors or any other
            entity; and

      (f)   any other circumstance of a similar or different nature that might
            otherwise constitute a defense available to either of the
            Guarantors as a guarantor.

            Except as provided above in this subsection 14.2, in no event shall
the obligations of the Guarantors hereunder exceed the obligations the
Guarantors would have had if either were itself a party to this Agreement, and
each of the Guarantors shall have all rights and defenses of the "Vendor" under
the terms of this Agreement.  This Guaranty shall continue to be effective, or
be  reinstated, as the case may be, if at any time any payment made, or any
part thereof, to the Owner by the Vendor under this Agreement or by either of
the Guarantors hereunder is ordered rescinded or must otherwise be returned by
the Owner to the Vendor or its representative for any reason,

                                      -67-
<PAGE>

including, without limitation, upon the insolvency, bankruptcy, reorganization,
dissolution or liquidation of the Vendor or otherwise, all as though such
payment had not been made.

            14.3  Waiver.  Each of the Guarantors hereby waives promptness,
                  ------
diligence, notice of acceptance and any other notice with respect to this
guaranty and any requirement that the Owner exhaust any right or take any
action against or with respect to the Vendor or any other person or entity or
any property.

            14.4  No Subrogation.  Notwithstanding any payment or payments
                  --------------
made by either of the Guarantors under or pursuant to this Section 14 or any
set-off or application of funds of either of the Guarantors by the Owner,
neither of the Guarantors shall, until all of the Vendor's obligations under
this Agreement (including warranty obligations) shall have been fulfilled, (a)
be entitled to be subrogated to any of the rights of Owner against the Vendor
or any other guarantor or in any collateral security or guaranty or right of
offset held by the Owner for the performance and payment of all of the
obligations of the Vendor under this Agreement, or (b) seek any reimbursement
or contribution from the Vendor or any other guarantor in respect of any
payment, set-off or application of funds made by either of the Guarantors under
or pursuant to this Section 14.

            14.5  No Petition.  Neither of the Guarantors will, without the
                  -----------
prior consent of Owner, voluntarily commence, or join with or solicit any other
person or entity in commencing, any case or other proceeding seeking
liquidation, reorganization or other relief with respect to the Vendor or its
debts under any bankruptcy, insolvency or other similar law now or hereafter in
effect or seeking the appointment of a trustee, receiver, liquidator, custodian
or other similar official of the Vendor.

            14.6  Continuing Guaranty: Assignments.  The Guaranty set forth
                  --------------------------------
in this Section 14 will be construed as a continuing, absolute and
unconditional guaranty of payment and performance, and, except as specifically
provided in subsection 14.1 above, the obligations of the Guarantors hereunder
will not be conditioned or contingent upon the pursuit by Owner at any time of
any right or remedy against the Vendor or against any other person or entity
which may be or become liable in respect of all or any part of the obligations
of the Vendor under this Agreement or against any collateral security or
guaranty therefor.  The Guaranty set forth in this Section 14 will (i) remain
in full force and effect until satisfaction in full of all the Vendor's
obligations under this Agreement, (ii) be binding upon each of the Guarantors
and their respective successors and (iii) inure to the benefit of and be
enforceable by the Owner and its successors, transferees and assigns.  Except
as may be necessary to fulfill its obligations hereunder in a timely manner,
and with the consent of Owner, not to be unreasonably withheld or delayed,
neither of the Guarantors will have any right, power or authority to delegate
all or any of its obligations hereunder; provided that upon any such
                                         -------- ----
delegation permitted hereunder, each of the Guarantors will nevertheless remain
liable for the performance of any obligations so delegated.

                  -----------
11.7, 11.8, 11.9, 11.10, 11.11 and 11.12 will apply to and be binding upon each
of the Guarantors to the same extent as such provisions apply to and are
binding upon the Vendor.  In executing this Agreement, each of QUALCOMM and
Sony are directly bound by the provisions of subsection 3.3 applicable to them,
in addition to their obligations as Guarantors hereunder.  For purposes of this
Agreement, any breach by either Guarantor of any representation or warranty in
this Agreement shall be deemed to only be a breach of such representation and
warranty by the Vendor, and not such Guarantor; provided that this
                                                -------- ----
sentence will in no way limit the Guarantors' obligations under Section 14.

      SECTION 15.  OTHER

            15.1  Owner Liabilities.  The Parties understand and agree that
                  -----------------
none of the Partners, nor any of their affiliates (other than the Owner), have
guaranteed or otherwise are now in any way liable with respect to any
obligations or liabilities of the Owner or any of its subsidiaries pursuant to
or in connection with this Agreement.  The Parties further understand and agree
that neither the Owner nor any of its subsidiaries will guarantee or otherwise
be in any way liable for any obligations or liabilities of any of the Partners
or any affiliate of the Owner pursuant to this Agreement unless, and only to
the extent the Owner or any one of its subsidiaries expressly agrees in writing
to guarantee or otherwise be liable for such liability.

            15.2  Counterparts.  This Agreement may be executed by one or
                  ------------
more of the Guarantors and the Parties to this Agreement on any number of
separate counterparts, and all of said counterparts taken together will be
deemed to constitute one and the same instrument.

         2.        Agreements.


         (a) The Owner hereby waives  its  rights  to (i) only those  liquidated
damages under Section 4 of the Contract which have accrued as of the date hereof
and are  due with  respect to the  Products which  were to be  delivered  by the
Vendor prior to the  date hereof and (ii) terminate  the Contract now or in  the
future  pursuant to the Contract's  treatment under  subsection 4.2(e) of Vendor
Product delivery  delays that  have occurred  prior to the date hereof.  Nothing
contained in this clause (a) shall in any way amend,  waive or otherwise  modify
the Owner's  rights  under the  Contract  as amended  hereby in the event of any
Vendor  delivery delay after the date hereof;  provided,  however,  any delivery
delays  that  occurred  prior  to  the  date  hereof  shall  not be  taken  into
consideration with respect to any future application of subsection 4.2(e) of the
Contract.


         (b)  Notwithstanding  the terms of the Contract and any Purchase Orders
delivered to the Vendor prior to the date hereof, the Vendor shall have and hold
specifically for the Owner the following  quantities of Specification  compliant
Subscriber Units (and their Material Accessories) at its manufacturing  facility
in San Diego, California no later than the dates set forth below:


           Date            Amount

         10/27/96          30,000
         11/10/96          70,000
         12/01/96          60,000
         12/05/96          20,000
         12/10/96          20,000

         It is agreed by the  Parties  that the  quantities  and dates set forth
above are firm and that no grace  periods  (including,  but not  limited to, the
Delay Grace Period) will apply to these dates and/or  quantities.  To the extent
the  quantities  of Products  set forth above are  manufactured  and held as set
forth in this clause (b) and clause (c) below by the dates set forth above,  the
Vendor  may  invoice  the  Owner  for  such  manufactured,   held  and  verified
Specification  compliant  Products  at the  prices  set forth on  Appendix  1 as
amended  hereby.  The 20,000  Subscriber  Units  to be  manufactured and held on
December 10, 1996, as set forth  above,  will be divided  between  10,000 "blue"
Subscriber  Units and 10,000 "green"  Subscriber  Units and  the Owner  and  the
Vendor will work together in good faith to promptly  agree and  establish  color
samples for such colored Subscriber Units;  provided,  however, in the event the
Parties fail to promptly reach such agreement, then the color of such Subscriber
Units shall be as set forth in Exhibit A1 and their  price shall not include the
price increase set forth in "Note 3" to Appendix 1. It is  expressly  understood
and  agreed by the  Parties  that in  the event the Vendor  shall for any reason
(other than an event  constituting a Force Majeure  pursuant to subsection 11.17
of the Contract in which case the terms of subsection 11.17 shall apply) fail to
comply with any  of the specific dates,  quantities  and other  requirements set
forth  in  this  clause (b) by  not  having  and  holding  such  quantities   of
Specification  compliant  Subscriber  Units  (and  their  Material  Accessories)
specifically for the Owner (as  verified  in  accordance with  clause (c) below)
at  the   Vendor's   manufacturing  facility  in  San Diego,  California,  then,
notwithstanding anything in the Contract to the contrary,  the Owner will  have
the right,  based upon the Owner's needs and  requirements, as determined in the
Owner's sole and absolute discretion and upon giving the Vendor  written notice,
within  three (3) Business Days  following  such failure or notice of failure by
the Vendor,  of the Owner's  election to  proceed  under either subclause (i) or
(ii) below, to:


(i) if the Owner does not need such Products, immediately (and without any grace
period whatsoever)  cancel, without  payment or penalty to  either the Vendor or
the Owners, any such  missing quantity  by lowering the Total Minimum Commitment
by the amount of such missing and or unverified Products; provided, that in such
event the Owner will have  the right  and the Vendor will  be obligated to treat
such  canceled  quantity of  Products  exactly  as  the  additional  thirty-five
thousand (35,000) Subscriber Units are being treated under  subsection 5.2(g) of
the Contract as added pursuant to this Amendment; or

(ii) if  the  Owner  does  not  need  such  Products,  accept such Specification
compliant Products as and when provided and verified by Vendor;  provided,  that
the  price of  any such  late Products  will be  reduced  by (x) one-half of one
percent (1/2%) for each  day late  (without any grace period whatsoever) and (y)
on the thirtieth day late, an additional five  percent (5%). In the  event  such
late Products are in excess of thirty (30) days late (starting  at 5:00 p.m. San
Diego time  on the  scheduled dates set forth  above), the Owner will again have
the right to cancel such late  Products as set forth  in subclause (i)  above to
the extent such  rights were not previously  exercised by the Owner with respect
to such late Products.

         (c) Any  Products  manufactured  and held  pursuant to clause (b) above
will be held by the Vendor in separately  identifiable  inventory, in individual
boxes or bulk  storage  boxes,  at the  Vendor's  manufacturing  facility in San
Diego,  California specifically for the Owner and any such held quantities will,
on or before the delivery  dates set forth  above,  be verified by the Vendor in
writing  to the Owner  identifying  the  quantity,  location,  model and  serial
numbers of the Products so held and further  identifying  such Products as being
held  for the  Owner  pursuant  to the  Contract  (provided  that  the  Vendor's
verification  of the  first  thirty  thousand  (30,000)  Subscriber  Units to be
available on October 27, 1996, will be dated November 4, 1996).  The Vendor will
provide  the Owner and its  personnel  reasonable  access to its  facilities  to
physically  verify the  availability  and  continued  maintenance  of  delivered
Products held for the Owner;  provided,  that the Owner will exercise its rights
(to the extent not previously  exercised) to physically  verify the availability
and continued maintenance of any such Products already verified by the Vendor to
the Owner  pursuant to and in accordance  with the first  sentence of clause (c)
within five (5) days after  receipt of any such  written  verification  from the
Vendor and provided  further  that  nothing  herein will prevent the Vendor from
sending an invoice to the Owner for any Vendor verified Products at any time (i)
after the Owner shall have  notified  the Vendor in writing of its intent not to
physically verify the availability and continued maintenance of such Products or
(ii) after  expiration of such five day period if the Owner  neither  physically
verifies nor provides notice of the Owner's  intention not to physically  verify
(in which event the Owner shall be deemed to have  verified  for purposes of the
third  sentence of clause 2(b)  above).  The Vendor will hold all such  Products
until  such time as the Owner  provides  written  notice to the  Vendor  that it
desires to have all or any portion of such held  Products  delivered  to the FOB
point for shipment;  provided, that the Owner will provide the Vendor with three
(3) days prior  written  notice to  individually  box any  Products  held by the
Vendor in bulk storage based upon a Vendor  individual box packaging  ability of
five thousand (5,000) Subscriber Units (and their Material Accessories) per day.
If for any  reason  the  Vendor  shall not,  on the  date(s)  scheduled  for the
delivery thereof, deliver to the FOB point any Products held for the Owner which
have been paid for by the Owner, then  (notwithstanding  subsection 11.17 of the
Contract), the Owner will have the absolute right to the immediate refund of any
monies paid to the Vendor for any such held but undelivered  Products,  and such
right will be in addition to any and all rights (subject to subsection  11.17 of
the  Contract)  the Owner may  otherwise  have in Contract or in law in any such
event.


         (d) The Vendor  will have a release of  software  ready for  conducting
phase 2 NSOTASP interoperability testing with the Owner's infrastructure vendors
on  November  15,  1996.  This  release of Software is intended to have and this
phase of testing is intended to verify the following NSOTASP functionality:  (a)
default factory configuration  complies to section 3.1 of IS-683; (b) an NSOTASP
call can be successfully  completed;  (c) a PCS call can be originated using the
newly  programmed  mobile;  (d) a PCS voice call can be  terminated by the newly
programmed mobile; (e) programming lock works properly; (f) the parameters of an
activated  mobile can be modified by an NSOTASP call;  (g) no permanent  data is
changed if the call is  terminated  before the  "Commit;"  (h) verify the PRL is
stored properly; and (i) mobile functions properly after downloading a list with
PRL with a size exceeding MAX_PR_LIST_SIZE.  Following successful passing of all
these phase 2 tests,  the Vendor  will,  within four weeks,  be in a position to
conduct  CDG  testing  with  the  Owner's  infrastructure  vendors.  Any and all
Subscriber  Units held at the Vendor's  facilities will be promptly  upgraded by
the Vendor to have such NSOTASP  Software upon  availability of NSOTASP Software
and  within  the  time  for  implementing  such  feature,  in each  instance  in
accordance  with and  pursuant  to the terms and  conditions  of Section  4.5 of
Exhibit A-1 of the Contract. The Vendor may invoice the Owner and the Owner will
pay  to  the  Vendor  $3.85  for  the  upgrading  of  each  such  satisfactorily
OTASP-upgraded Subscriber Unit.


         (e) The  liquidated  damages  provisions  of  subsection  4.2(a) of the
Contract  shall  not  apply  to  those  1996   forecasted   Products  which  are
specifically subject to liquidated damages,  price reduction and/or cancellation
pursuant to the provisions of subsection 2(b)(i) or 2(b)(ii) of this Amendment.


         3. Amendment to Subsection 3.2(a). Subsection 3.2(a) of the Contract is
hereby amended by deleting the seventh sentence thereof  commencing "For each of
the Initial Subscriber Units ..." in its entirety.


         4. Amendment to Subsection 3.2(b). Subsection 3.2(b) of the Contract is
hereby amended by (i) changing the  definition of "Total Minimum  Commitment" in
the first sentence  thereof from  one million one  hundred ninety five  thousand
(1,195,000)  Subscriber  Units  to  "one  million  one  hundred  sixty  thousand
(1,160,000)Subscriber  Units" and (ii) changing the  definition of "First Annual
Minimum Commitment" in the second sentence thereof from  two hundred thirty five
thousand  (235,000)   Subscriber  Units  to  "two  hundred   thousand  (200,000)
Subscriber Units".


5. Amendment to Subsection 5.1. Subsection 5.1 of the Contract is hereby amended
by  adding a new  subsection  5.1(d)  immediately  after  subsection  5.1(c)  as
follows:

                  "(d)  Notwithstanding  anything stated herein (including,  but
         not limited to,  Schedule 8 hereto) to the contrary,  to the extent the
         Owner shall have  forecasted for the delivery of any  Accessories,  the
         Owner may reduce the aggregate Accessory deliveries  forecasted for the
         first  three  (3)  months of 1997,  by an amount  equal to no more than
         [______]  percent of the amount of  Accessories  purchased by the Owner
         from the  Vendor  in 1996  (over  and  above  any  quantity  reductions
         available to the Owner for the first three (3) months of 1997  pursuant
         to  subsection  5.1);  provided,  that  any  such  reduction  shall  be
         distributed evenly over the first three (3) months of 1997."


6. Amendment to Subsection 5.2. Subsection 5.2 of the Contract is hereby amended
by  adding a new  subsection  5.2(g)  immediately  after  subsection  5.2(f)  as
follows:

                  "(g)  Notwithstanding  anything stated herein to the contrary,
         at any time  throughout  the Initial Term the Owner may in its sole and
         absolute  discretion choose to order up to  [_____________]  additional
         Specification   compliant   Subscriber   Units  (and   their   Material
         Accessories)  above the Total Minimum  Commitment.  If the Owner should
         order  any  such  additional   Subscriber  Units  (and  their  Material
         Accessories)  for delivery at any time in 1996, any such order for such
         additional  Products will be deemed an Excess Purchase Order and to the
         extent  fulfilled  by the Vendor,  will be  fulfilled at a price not in
         excess of [_____________] percent less than the 1996 price set forth on
         Appendix  1.  If  the  Owner  desires  to  order  any  such  additional
         Subscriber Units (and their Material  Accessories) for delivery in 1997
         or 1998 then, the Owner shall include such additional  Subscriber Units

          competitive  products in a commercially  reasonable  manner,  and with
          respect to pagers and paging service, until such time Sprint or Sprint

          programs;  provided,  however, RadioShack will not market or otherwise
          offer  for  sale  in the  Merchandising  Display  or in an area of the
          Retail Store immediately adjacent to the Merchandising Display (taking

          typical  Retail  Store)  any  product or  service  competitive  to the
          Products  and  Services  merchandised  in the  Merchandising  Display,

          Spectrum will have the right to use the specific Mark combinations set
          forth on the Excluded Marks Addendum with the name of any other Person
          or Retailer  including  RadioShack  (provided the name "RadioShack" is
          not used in Combination  Mark Format) and may use any Sprint or Sprint
          Spectrum Mark together  with the name of any  individually  identified
          product or service of Sprint or Sprint Spectrum in connection with the
          name of any other Person  provided that such use is never  interlocked
          or  connected  with the name of a Retailer by the "@" symbol or by the
          word "at" if the use of the word "at" is exclusively  auditory and not
          accompanied  by a visual  presentation  (e.g.,  both "Sprint  Sense at
          Retailer" and "Sprint PCS at Retailer"  would be permissible  usage in
          print  media  and  on  television  if  depicted   visually,   even  if
          accompanied by audio voice-over, but would not be permissible usage on
          radio or on television  if not  accompanied  by a visual  depiction of
          "Sprint Sense at Retailer." "Sprint Sense @ Retailer" or "Sprint PCS @
          Retailer"  are  not  permissible   usages  no  matter  what  media  or
          combination of media used because of the inclusion of the "@" symbol);

          and RadioShack will have the right to: (1) offer for sale or lease, as
          applicable all generally  available  Products,  (2) solicit orders for
          all generally available Services,  and (3) offer or solicit orders for
          all generally available  Product/Service  Bundles which include any of
          the Products and Services,  offered as of the Effective Date or in the
          future by Sprint or Sprint Spectrum,  including all mass marketed rate
          plans  for those  Services  offered  by  Sprint  or  Sprint  Spectrum;
          provided, however, that Sprint and Sprint Spectrum may offer from time
          to time, through direct  distribution  channels or special third party
          corporate promotional  programs,  Products,  Services,  rate plans for
          such  Services,  and  Product/Service  Bundles not advertised as being
          generally  available  through  RadioShack  Retail  Stores  if (1)  the
          general terms and  conditions of each such  promotion to be offered to
          consumers  are first  communicated  to  RadioShack by Sprint or Sprint
          Spectrum,   as  the   case   may  be,   subject   to  any   applicable
          confidentiality   agreements   with   respect   to   proprietary   and
          confidential   information   and  (2)  RadioShack  is  compensated  in
          accordance  with the  provisions  of  subsection  4(e) below,  if such
          promotion is available to, offered by and sold by RadioShack;

     (v)  All goodwill resulting from the use of individual trademark or service
          mark usage as part of the  Combination  Marks by the Parties inures to
          the benefit of the  respective  individual  trademark  or service mark
          owner. No Party acquires rights,  title or interest in the Combination
          Marks or the goodwill  associated  with them,  other than the right to
          use the  Combination  Marks in  accordance  with  this  Agreement.  In
          accepting this  Agreement,  all Parties  acknowledge  ownership of the
          respective individual Marks which comprise the Combination Mark, their
          validity and the goodwill  connected  with them.  The Parties  further
          agree not to make any application to register the  Combination  Marks.
          This paragraph will survive the termination of this Agreement.

     (vi) With respect to all Sprint branded consumer, residential,  single-line
          telephones   (other  than  PCS   equipment)   Sourced  by  RadioShack,
          RadioShack  will have the  exclusive  right to sell those  Products at
          retail;

          Retailer (other than Sprint or Sprint  Spectrum  Company Owned Stores)

          6-Telephone Products;

     (x)  Sprint  and  Sprint  Spectrum  will  use all  commercially  reasonable
          efforts to assist Tandy Service, a division of Tandy  Corporation,  to
          obtain from Sprint and Sprint  Spectrum's  Product vendors  authorized
          service  center  agreements  permitting  Tandy  Service  to repair all
          Products subject to this Agreement.

     (d) During the term of this  Agreement,  neither Sprint nor Sprint Spectrum
will own or lease a Company  Owned Store,  kiosk or other  similar  facility not
located  within a Retailer,  unreasonably  close to the current  location of any
RadioShack Company Owned Store or participating independent RadioShack dealer or
franchisee's store, all as of the Effective Date.

     (e)  RadioShack  shall be  compensated  by  Sprint or  Sprint  Spectrum  in
accordance with the terms of each Addendum  relating to a Product or Service but
in all cases (except Internet  products and services and Spree cards) consistent
with the general  principles  that (1) if the sale of the Product is made or the
order for the Service is placed  through a Retail Store,  RadioShack is entitled
to be compensated  for acquiring  that  customer,  and (2) if on the date of the
sale of the Product or Service  order  placement  the  customer is not already a
current Sprint or Sprint Spectrum Service customer,  said customer will be given
a unique source code by Sprint or Sprint Spectrum identifying said customer as a
RadioShack  acquired  customer  and  RadioShack  shall be  entitled  to  receive
residual  compensation for the period of time said RadioShack  acquired customer
remains a Sprint or Sprint Spectrum  customer for any Service during the term of
this Agreement and for two years after the termination of this Agreement. In the
event a RadioShack  acquired customer  terminates all Service during the term of
this Agreement and  subsequently  resumes Service with Sprint or Sprint Spectrum
during the term of this Agreement,  no residual  compensation will be payable to
RadioShack  with respect to said  re-acquired  customer  unless such customer is
re-acquired by RadioShack.

     (f) With respect to the offer and sale of Products and the  solicitation of
orders for Services,  the Parties  intend this Agreement to be national in scope
and coverage.  Subject to the terms and conditions of this Agreement and Addenda
attached  hereto  (including,  without  limitation,  JSC  approval)  and  unless
precluded by judicial or governmental order or action, RadioShack will commence,

of Products  and the  solicitation  of orders for Services as and when agreed as
set forth in this  Agreement  or any  applicable  Addendum  after such  Products
and/or  Services are made  available in a market  within the  Territory.  Should
RadioShack  be  precluded  by a judicial  or  governmental  order or action from
offering  a Product  or  soliciting  an order  for a  Service,  RadioShack  will
expeditiously remove the impediment to continuing sales and marketing activities
and,  specifically  relating to the  solicitation  of orders for Sprint Spectrum
PCS, RadioShack shall take all necessary action to be able to solicit orders for
Sprint Spectrum PCS. In this regard,  RadioShack will negotiate,  renegotiate as
necessary,  and  include  in each  Cellular  Radio  Service  Referral  Agreement
executed  between  RadioShack  and a CRS carrier  after the  Effective  Date the
definition of CRS  substantially in the form contained in this Agreement or such
other  provisions  as are  necessary to permit  RadioShack to offer for sale PCS
Equipment  and solicit  orders for Sprint  Spectrum PCS or, in the  alternative,
obtain from each CRS carrier  written  assurances that the offer and sale of PCS
Equipment  and  the  solicitation  of  orders  for  Sprint  Spectrum  PCS is not
prohibited by the Cellular Radio Service  Referral  Agreement  executed  between
RadioShack and such CRS carrier.

5. Joint Steering  Committee - RadioShack  will appoint two (2)  representatives
and Sprint and Sprint Spectrum will each appoint one (1) representative to serve
as members of a four (4) person  Joint  Steering  Committee,  each of whom shall
hold a position of assistant  vice-president  or higher  within each  respective
Party.  The Joint Steering  Committee will be responsible  for all joint issues,
including  Program rollout timing and strategy,  and deciding which Products and
Services  will  be  sold  through   certain  Retail  Stores.   Consistent   with
RadioShack's commitment to Sprint Spectrum PCS set forth in Section 4(f) of this
Agreement, RadioShack, acting through its Joint Steering Committee members, will
not use as a reason for  withholding  approval of the placement of PCS Equipment
and/or Sprint  Spectrum PCS in a Retail Store the existence of a Cellular  Radio
Service Referral  Agreement with a CRS carrier or the threat of a CRS carrier to
terminate any such agreement if RadioShack introduces Sprint Spectrum PCS into a
Retail Store(s) in that CRS carrier's  market(s).  The Joint Steering  Committee
will also meet to discuss  marketing  expenditures  and  strategies  and will be
primarily   responsible   for   providing   initial   approval   of  all   joint
advertisements.

     Except as provided in Section 7 below,  advertising and market  development
fund expenditures,  expenses and allowances with regard to specific Products and
Services will not be a subject for the Joint Steering Committee, but rather will
be subject to the guidelines set forth in the specific  Addendum related to that
Product or Service.  The JSC will establish,  from time to time,  guidelines for
general routine print, broadcast and electronic media advertising to govern each
Party's  unilateral  advertising  and promotion of the Products and Services and
which  also  contains  one or  more  of the  RadioShack  Marks  and  one or more
Sprint/Sprint Spectrum Marks. Each Party agrees any other Party may unilaterally
advertise the Products and Services in this manner,  without JSC  approval,  but
only if that Party complies in all material  respects with the JSC's  guidelines
for such advertising.

     The Joint Steering  Committee will also be responsible  for operational and
implementation  issues  not  specifically  addressed  in this  Agreement  or the
Addenda.

     The JSC will  also be  responsible  for  making  recommendations  regarding
modifications  to the  terms  of this  Agreement,  including  the  terms of each
Addendum  attached hereto,  to respond to market  conditions and concerns of the
Parties  hereto,  subject  in all  cases to  applicable  laws,  regulations  and
contracts with third parties.

     The JSC may  authorize  legal  action in the name of any or all  Parties in
response  to  legal  threats  to the  ability  of any  Party  to  fulfill  their
obligations under this Agreement, and will, in that event, have the authority to
retain counsel and allocate the costs of such counsel and related expenses among
the Parties.

     The Joint  Steering  Committee  will meet as often as  necessary  either in
person  or by  telephone,  but not less  than  four  times per year in person at
mutually  acceptable  times  and  locations.  Any  member  of  the  JSC  may  be
represented  by proxy if  unavailable  to attend in person or by telephone.  Any
Party  may call a JSC  meeting  upon  seven  (7) days  written  notice.  At each
meeting,  each  member  of the JSC may bring  one or more  additional  advisors,
experts or vendors to  participate  in the meeting.  All  decisions by the Joint
Steering Committee must be unanimous to be binding on the Parties.

6.   Merchandising Displays

     (a) The Parties agree to  collaborate  on the design and approve the format
of the  Merchandising  Display for the promotion of the Products and Services to
be placed inside those Retail Stores deemed  appropriate  by the Joint  Steering
Committee.  Each  Merchandising  Display  will  consist  of  two  categories  of
components: (1) a computer interface with related accessories, and (2) fixtures,
each as  specified  in a Computer  Interface,  Fixtures,  and Floor Plan  Design
Addendum to be developed in  accordance  with Section 6(b) below and attached as
an Addendum hereto.

     (b)  The  Parties  acknowledge  that  the  installation  of an  appropriate
Merchandising  Display in the  Retail  Stores is  fundamental  and  material  to
achieving the goals of the Program.  The Parties agree to meet and determine the
specifications  of the  Merchandising  Displays  including  the  cost,  size and
location of the Merchandising Displays,  applicable fixtures and displays within
each  representative  RadioShack floor plan, and the cost breakdown  between the
fixtures  and the  computer  systems,  all to be set  forth on  Addenda  to this
Agreement.

     (c) Sprint and Sprint  Spectrum  will each commit,  subject to Section 6(b)
above, $[___________], if necessary, for an aggregate total of $[_____________],
to offset the initial costs of the design, development, production, acquisition,
construction and installation of the Merchandising Displays.

     (d)  RadioShack,  by and through its Real  Estate  Design and  Construction
Department,  will have charge and  supervision  of the  construction,  shipment,
installation,  relocation,  remodeling  and  replacement  of  the  Merchandising
Displays in the  RadioShack  Company  Owned Retail  Stores.  RadioShack,  in the
performance of such work, may contract and subcontract  with others for portions
of the work in the same manner as done with  respect to similar  work,  provided
Sprint/Sprint  Spectrum  will  have the right to  approve  all  contractors  and
subcontractors who are Affiliates of RadioShack. Sprint and Sprint Spectrum will
pay RadioShack for all actual out-of-pocket  Merchandising  Display Expenditures
advanced,  paid or reasonably incurred by RadioShack in the course of doing such
work,  provided  these costs will not include a profit to  RadioShack or include
RadioShack  overhead,  internal salaries and wages. Payment shall be made within
thirty (30) days of the date of an invoice by RadioShack for such  out-of-pocket
Merchandising  Display  Expenditures.  The invoice  shall state,  in  reasonable
detail,  the  amount  and  nature  of the  out-of-pocket  Merchandising  Display
Expenditures  and the date and to whom  advanced,  paid or incurred.  Sprint and
Sprint Spectrum, in like manner, will pay RadioShack for all other out-of-pocket
Merchandising Display Expenditures (and any other costs, charges or expenditures
allocable to Sprint and Sprint Spectrum under this Agreement) advanced,  paid or
incurred by RadioShack.

     (e) Sprint and Sprint  Spectrum will each have and retain all right,  title
and interest to the  Merchandising  Displays.  RadioShack will have the right to
relocate and reinstall an existing  Merchandising Display upon the relocation or
closure of each respective Retail Store at RadioShack's sole cost and expense.

     (f) The Parties will  determine as part of the process set forth in Section
6(b)  above  the per store  cost of the  Merchandising  Display  for each of the
representative RadioShack Retail Store floor plans and the incremental cost over
the budgeted  construction cost of installing a new  Merchandising  Display in a
newly  builtout  Retail Store.  With respect to each newly  builtout  RadioShack
Company Owned Store opened after the Effective Date,  Sprint and Sprint Spectrum
will pay the incremental cost reasonably  incurred to install the  Merchandising
Display  in  such  newly  builtout   RadioShack  Company  Owned  Stores,   which
incremental  cost  shall be capped at and will not exceed  the  appropriate  per
store cost of the  Merchandising  Display  for an existing  Retail  Store on the
Effective Date.

     (g)  After  the  initial  installation,  RadioShack  will  bear the cost of
insuring,  maintaining and repairing the fixtures contained in the Merchandising
Display  (including  replacement  due to casualty  loss or damage),  but not the
computer interface.  After the initial installation,  Sprint and Sprint Spectrum
will  bear  the cost of  insuring,  maintaining,  repairing  and  replacing  the
computer interface in the Merchandising  Display  (including  replacement due to
casualty loss or damage).

     (h) If the Merchandising  Display becomes obsolete, in whole or in part, or
needs remodeling,  each as determined by the Joint Steering Committee, the costs
of remodeling or obsolescence  replacement of the Merchandising Displays will be
borne  by  Sprint  and  Sprint  Spectrum.  Upon  obsolescence  or  as  otherwise
determined  by the JSC,  RadioShack  will  have the  right to sell or  otherwise
dispose of such  Merchandising  Displays at RadioShack's sole cost and the right
to retain the proceeds of any such sale or  disposition  without  accounting  to
Sprint or Sprint Spectrum,  provided,  however,  that Sprint and Sprint Spectrum
shall  have an option to retain  the  entirety  or any  useable  portion  of the
Merchandising  Display upon  replacement,  by giving  RadioShack  written notice
within thirty (30) days after receiving written notice of RadioShack's intent to
sell or otherwise dispose of such  Merchandising  Display.  If Sprint and Sprint
Spectrum  exercise  this  option,  the  unamortized  cost of such  Merchandising
Display(s) or useable portion thereof shall be credited  against the unamortized
costs referenced in Section 20(b) below.

     (i) Sprint and Sprint Spectrum  hereby grant to Tandy Cabinets,  a division
of TE Electronics Inc., a wholly owned subsidiary of Tandy Corporation,  a right
to bid on the fabrication and construction of the fixtures for the Merchandising
Display.

     (j)  Sprint and  Sprint  Spectrum  shall be  responsible  for all  personal
property taxes due and payable attributable to the Merchandising  Displays.  The
Parties shall cooperate in exchanging  information necessary for a Party to file
any  necessary  tax  returns  with  respect to its  property.  Sprint and Sprint
Spectrum will be responsible  for filing all personal  property tax returns with
respect  to the  Merchandising  Displays  and for the  payment  of all  personal
property taxes in connection  therewith.  RadioShack  will reimburse  Sprint and
Sprint Spectrum for 50% of the taxes actually paid by Sprint and Sprint Spectrum
within  thirty (30) days after  receipt of an invoice from Sprint  and/or Sprint
Spectrum with supporting documentation of the tax and payment thereof attached.

efforts to reach the Market  Launch Date no later than  October 1, 1997.  Sprint
will contribute $[___________] and Sprint Spectrum will contribute $[__________]
and RadioShack will contribute  $[___________]  to the initial  promotion of the
rollout  of the  Program  after the  Market  Launch  Date.  The  Joint  Steering
Committee will determine when and how to spend the combined $[___________],  and
what expenditures will be counted as market launch expenditures as distinguished
from expenditures under subsection (b) below.

     (b) Unilateral Advertising Commitments.

     (i)  During  the term of this  Agreement,  RadioShack  will  include  those
          Combination Marks or Sprints Marks, as appropriate,  in all RadioShack

          including but not limited to, print,  broadcast and electronic  media.
          The Parties agree that RadioShack spend at least  $[_____________] and
          Sprint will spend at least  $[_____________]  and Sprint Spectrum will
          spend at least $[_____________] of such Party's respective advertising
          budgets for each of the first two twelve (12) month periods  beginning
          on the Market Launch Date,  and the first  anniversary  thereof during
          the term of this  Agreement  for the  broadcast,  print or  electronic
          media marketing and communications of the Products and Services. These
          promotions  will  include  one or more  of the  Combination  Marks  in
          advertising  consistent  with  the  standards  adopted  by  the  Joint
          Steering Committee.  Beginning for the calendar year beginning January
          1, 1999,  each Party's  advertising  commitment  under this subsection
          (b)(i) will remain the same as their  commitment  for the  immediately
          preceding calendar year, unless such Party notifies the other Party at
          least  six (6)  months  before  (beginning  July 1, 1998 and each year
          thereafter)  the  beginning  of such  year of that  Party's  desire to
          change their  commitment and before September 30, before the beginning
          of such year (beginning September 30, 1998, and each year thereafter),
          the respective Party discloses through their respective JSC member the
          size of the Party's commitment,  provided in no event will the size of
          any Party's (i.e.,  Sprint and Sprint Spectrum  collectively for these
          purposes,  and RadioShack)  commitment under this subsection (b)(i) be
          less than  $[______________].  Each Party will be obligated to satisfy
          that  commitment,  provided,  neither party will be obligated to spend
          more  than  the  amount  that is the  lower  of the  two  (2)  amounts
          submitted to the JSC.

     (ii) Each Party may satisfy its obligation under this Section as that Party
          decides in its sole discretion,  provided that  advertising  generally
          will include  direct mail,  newspaper  inserts,  television  and radio
          campaigns,  Yellow Page advertising  including the Sprint Marks or the
          Sprint Spectrum Marks, RadioShack Marks and the Combination Marks, and
          conspicuous store signage within each Retail Store, all subject to the
          prior  approval  of the JSC and each  Party  pursuant  to the terms of
          their  respective  Mark  licenses  or  their  respective   advertising
          guidelines concerning Marks.

     (iii)Nothing  in this  Section  prohibits  Sprint or Sprint  Spectrum  from
          tagging or promoting  any other  Retailer or  distribution  channel in
          advertising  which is not  designated  as part of the  commitment  set
          forth in Section  7(b)(i)  above,  provided the  advertising  does not
          include any of the Combination Marks or violate Section 4(c)(i) above.

     (c) Training Costs. The Parties intend that Sprint and Sprint Spectrum will
provide  trainers for the purpose of training  designated  RadioShack  employees
("RadioShack Trainers") who then will train all appropriate RadioShack employees
with respect to the Products and Services.  The Joint  Steering  Committee  will
determine the appropriate  level of necessary  training and the specific details
of such  training.  Sprint  and  Sprint  Spectrum  will be  responsible  for all
reasonable  costs relating to the initial  training of RadioShack  Trainers with
respect to their individual  Products and Services,  and any subsequent training
of the  RadioShack  Trainers  with respect to, and including but not limited to,
existing or new Products and Services offered during the term of this Agreement,
by such Party. Except as provided below,  RadioShack will be responsible for all
costs  relating to the cost of training  RadioShack's  employees and the cost of
meeting internal certification standards.  RadioShack will pay one-half,  Sprint
one-fourth,  and  Sprint  Spectrum  one-fourth  of the  costs  of  developing  a
certification  module  for  the  Program  and  incorporating  said  module  into
RadioShack's  training  program.  Except as provided above,  RadioShack will pay
one-half,  Sprint  one-fourth,  and Sprint  Spectrum  one-fourth of the training
costs of RadioShack's employees and of meeting internal certification  standards
in the following manner:  RadioShack will pay one-half,  Sprint one-fourth,  and
Sprint   Spectrum   one-fourth   of  the  initial  cost  of  production  of  the
certification  materials and test sheets, in a total amount estimated to be less
than $25,000 (each  one-fourth  to be estimated to be less than $6,250).  Sprint
will  pay  one-half  and  Sprint  Spectrum  will pay  one-half  of the cost of a
certification  training video  (estimated  total cost to be between  $25,000 and
$50,000).  Sprint will pay one-half and Sprint Spectrum will pay one-half of the
duplication cost of a certification  training video (estimated to be $3 per tape
for 5,000 tapes for a total of $15,000).  RadioShack  agrees to distribute these
video  tapes at no cost to  Sprint  and  Sprint  Spectrum.  RadioShack  will pay
one-half, Sprint one-fourth and Sprint Spectrum one-fourth of the maintenance of
this program, up to a maximum of $10,000 total per year ($2,500 per one-fourth).
The  certification  material  and  video  must be  approved  by the  JSC  before
distribution and use thereof.

     (d) Payment.  The Party paying,  advancing or incurring any cost or expense
under this  Agreement  shall  invoice the other Party for the other's  allocable
share.  The other  Party  will pay its  share  within  thirty  (30) days of such
invoice.

     (e) Other  Program  Expenses.  The  Parties  anticipate  that there will be
additional  costs and  expenses  incurred  by the  Parties  with  respect to the
Program during the term of this Agreement.  Unless otherwise  mutually agreed by
the  Parties,  all such costs and expenses  will be borne  entirely by the Party
incurring such costs and expenses.

8.   Acceptance of Orders for Services and  Cancellation,  Customer  Service,
     Discontinuance of Service or Shortage of Capacity

     (a) Orders submitted by customers who sign up through RadioShack for Sprint
or Sprint  Spectrum  Services are not binding on Sprint or Sprint Spectrum until
accepted  by Sprint or Sprint  Spectrum.  Each of  Sprint  and  Sprint  Spectrum
reserve  the right at its sole  discretion  to  decline  to accept any order for
their respective Services solicited or taken by RadioShack,  provided Sprint and
Sprint Spectrum,  as the case may be, will not discriminate against or apply any
more stringent  standards  upon  RadioShack  customers than any other  potential
Sprint or Sprint Spectrum customer.  Sprint and Sprint Spectrum may, for a valid
business purpose,  cancel or suspend any order for Services,  either in whole or
in part, without liability to RadioShack, at any time after acceptance by Sprint
and Sprint  Spectrum.  Sprint and Sprint  Spectrum  further reserve the right to
allocate  their  Services  during  periods of shortages  without  incurring  any
liability to RadioShack for payment of compensation hereunder. Sprint and Sprint
Spectrum may discontinue  offering for sale or the actual sale of any Product or
Service,  notwithstanding  the fact that it may be listed on any of the attached
Addenda,  provided in such  event,  RadioShack  may offer in the Retail  Store a
competitor's  products or services  (provided such products and services are not
merchandised in the immediate vicinity of the Merchandising  Display) to replace
those Products or Services  discontinued  by Sprint or Sprint  Spectrum,  unless
such discontinued Products or Services are replaced by Sprint or Sprint Spectrum
with  reasonably  comparable  services  within  a  reasonable  time  after  such
discontinuation.

     (b) Sprint and Sprint  Spectrum  shall provide  customer  service for their
respective  Services  in  accordance  with  each of  their  respective  standard
practices and customer  agreements.  Customers for Services will be customers of
Sprint and/or Sprint Spectrum and shall remain customers of Sprint and/or Sprint
Spectrum after termination of this Agreement.

be approximate only.

9.   Sprint Trademark License

     (a) License. Sprint grants to RadioShack a non-exclusive,  nontransferable,
revocable license,  without the right to sublicense,  to use the Sprint Marks as
set forth in the Agreement in the Territory in connection  with the provision of
the  Products  and  Services  set  forth on the  Addenda  attached  hereto.  For
Services,  RadioShack  has the  right to use the  Sprint  Marks to  promote  and
solicit  orders  for  those  Sprint  Services  identified  in the  Addenda.  For
Products,  RadioShack has the right to use the Sprint Marks on those  quantities
of  RadioShack-sourced  residential  consumer  telephones,  as  defined  herein,
approved  by  Sprint,  and to  promote,  offer for sale and sell  Sprint-sourced
Products identified in the Addenda,  provided, nothing in this Agreement permits
RadioShack to use Sprint Marks to brand,  co-brand or dual-brand any products or
services without  Sprint's prior written consent,  which consent may be withheld
in Sprint's sole discretion for any reason, including but not limited to failure
to be supplied with acceptable product warranties and  indemnification  relating
to such products.

     (b) Use of Marks.  RadioShack  agrees to use the  Sprint  Marks only as set
forth in the Sprint  Trademark  Usage  Guidelines,  and in this Agreement and to
follow the standards of quality  established by Sprint.  RadioShack must not use
the Sprint Marks in combination with any other trade name,  trademark or service
mark,  including  RadioShack's Marks except as otherwise set forth in the Sprint
Trademark  Usage  Guidelines  and in this  Agreement,  without the prior written
approval of Sprint.

     (c) Sprint or Sprint Spectrum after providing  written notice to RadioShack
of a breach of any trademark license provision, and after providing a reasonable
time to cure such  breach,  but not less than  thirty  (30)  days,  may,  at its
option,  take those  actions  reasonably  necessary to protect  Sprint or Sprint
Spectrum's  trademark rights.  Notwithstanding the foregoing,  a breach of these
license provisions may give rise to irreparable injury; consequently,  Sprint or
Sprint  Spectrum may seek  injunctive  relief without  entering into any dispute
resolution or arbitration process.

     (d) Control of Marks.

     (i)  Sprint has the right, at all reasonable times, to inspect RadioShack's
          relevant facilities and review the manner in which RadioShack provides
          products  and  services  so that  Sprint may  satisfy  itself that the
          products  and  services  with  which  the  Sprint  Marks are used meet
          Sprint's established standards.

     (ii) RadioShack   agrees  to  adhere  to  the  trademark  usage  guidelines
          furnished  by Sprint for the  depiction  of the Sprint Marks (" Sprint
          Trademark Usage  Guidelines").  The attached Exhibit 9(d)(ii) "Summary
          of Brand  Identity  Standards,  December,  1995" will  function as the
          current  ver-  sion  of  the  Sprint   Trademark   Usage   Guidelines.
          (iii)RadioShack   agrees  to   include  on  the   packaging   of  each
          RadioShack-sourced,  Sprint-branded  Product,  on all  advertising and
          promotional  materials,  and on all labels  bearing  any of the Sprint
          Marks the following notice:

                    "[Sprint Mark] is a registered* trademark of Sprint Communi-
                         cations Company L.P. Used under license."

                    *    "Registered"  - to  be  used  only  when  the  Mark  is
                         registered in the USPTO.

     (iv) RadioShack agrees that, except with respect to materials substantially
          identical to materials that have  previously  been  approved,  it will
          furnish to Sprint for trademark usage approval prior to any use of the
          Sprint  Marks  a  sample  of  each  use of the  Sprint  Marks  that is
          different from previously approved usages on advertising,  promotional
          materials, packaging and labels. RadioShack agrees to amend the use of
          the  Sprint  Marks in any  such  advertising,  promotional  materials,
          packaging  or labels if the use of the Sprint Marks is not approved by
          Sprint in accordance with the terms of this Agreement. RadioShack will
          use  all  commercially   reasonable   efforts  to  provide  sufficient
          submission  lead times to allow  Sprint  adequate  review and approval
          time on trademark usage of Sprint Marks by RadioShack. Sprint will use
          all commercially  reasonable efforts to provide trademark usage review
          and approval within the time constraints  applicable to the conduct of
          RadioShack's   retail   operations   and  the  specific   advertising,
          promotional,  packaging or label usage  proposed for the Sprint Marks.
          If,  however,  such  approval is not received by  RadioShack  within 5
          business days of the date of receipt by Sprint of such materials, such
          materials will be deemed approved unless Sprint and RadioShack  agrees
          on a longer  period of time for  approval of specific  materials.  All
          materials will be sent for approval to:

                    Patrice  Dougherty,  Sr.  Intellectual  Property  Analyst
                       Sprint Communications Company L.P.

                    Facsimile: (913) 624-6388

     (v)  RadioShack must not offer for sale, advertise, promote, distribute, or
          use for any purpose any RadioShack-sourced,  Sprint-branded Product or
          associated packaging that is damaged,  defective, is a second, or that
          otherwise fails to meet the  specifications  and quality  requirements
          listed in  Exhibit  12(c)(i)  without  the prior  written  consent  of
          Sprint.


     (e) Royalties. Sprint provides this license royalty-free to RadioShack.

     (f) Rights in Marks.

     (i)  All uses of the Sprint Marks by RadioShack inure to the benefit of
          Sprint. RadioShack acquires no rights, title or interest in the Sprint
          Marks or the goodwill  associated  with them,  other than the right to
          use the Sprint Marks in accordance with this  Agreement.  In accepting
          this  Agreement,  RadioShack  acknowledges  Sprint's  ownership of the
          Sprint Marks,  their  validity and the goodwill  connected  with them.
          RadioShack  shall not attack the Sprint  Marks,  nor assist  anyone in
          attacking them.  RadioShack further agrees not to make any application
          to  register  the Sprint  Marks,  nor to use any  confusingly  similar
          trademark, service mark, trade name, or derivation, during the term of
          this  Agreement  or  thereafter.   This  paragraph  will  survive  the
          termination of this Agreement.

     (ii) At the  request  of  Sprint,  RadioShack  will  execute  any papers or
          documents  reasonably necessary to protect the rights of Sprint in the
          Sprint  Marks and execute and deliver  such other  documents as may be
          reasonably  requested by Sprint.  (g)  Infringement.  RadioShack shall
          promptly  notify  Sprint of any  unauthorized  use of the Sprint Marks
          that comes to  RadioShack's  attention.  Sprint in its sole discretion
          may take such action as may be required to prosecute the infringement.
          In the event that Sprint  decides that action  should be taken against
          such  third  parties,  Sprint may take such  action  either in its own
          name, or  alternatively,  Sprint may authorize  RadioShack to initiate
          such action in RadioShack's  name. In either event,  RadioShack agrees
          to cooperate  fully with Sprint to whatever  extent it is necessary to
          prosecute  such  action,  all  expenses  being borne by Sprint and all
          damages which may be recovered being solely for the account of Sprint.

     (h) Indemnification.

     (i)  Except  as set  forth  herein  and in  Section  18 of this  Agreement,
          RadioShack shall defend, indemnify and hold harmless Sprint and Sprint
          Spectrum,   their  subsidiaries,   officers,   agents,  employees  and
          Affiliates  from all Damages  arising out of or resulting from any act
          or omission of RadioShack  relating to claims for  unauthorized use or
          misuse of any Sprint/Sprint Spectrum Mark.  Notwithstanding the above,
          RadioShack  shall  not  be  responsible  for  and  shall  not  defend,
          indemnify or hold harmless  Sprint or Sprint Spectrum from any Damages
          arising out of or resulting from claims of trademark infringement that
          are based  solely on depicting  the  Sprint/Sprint  Spectrum  Marks in
          accordance with the Sprint Trademark Usage Guidelines,  or pursuant to
          other authorization by Sprint or Sprint Spectrum, as the case may be.

10.  Sprint Spectrum Trademark License

     Sprint  Spectrum has no marks to be licensed under this  Agreement.  If the
Parties  later  desire to  license  any  Sprint  Spectrum  Marks,  they agree to
negotiate a Trademark License  substantially  similar to the Trademark  Licenses
provisions contained in this Agreement.

11.  RadioShack Trademark License

     (a)  License.  RadioShack  grants  to Sprint  and  Sprint  Spectrum  each a
non-exclusive,   nontransferable,   revocable  license,  without  the  right  to
sublicense,  to use the  RadioShack  Marks as set forth in this Agreement in the
Territory in  connection  with the promotion of the sale and use of the Products
and Services set forth on the Addenda attached hereto.

     (b) Use of Marks.  Sprint and Sprint  Spectrum  agree to use the RadioShack
Marks only as set forth in this Agreement and to follow the standards of quality
established  by  RadioShack.  Sprint  and  Sprint  Spectrum  must  not  use  the
RadioShack Marks in combination with any other trade name,  trademark or service
mark, except as otherwise set forth in the RadioShack Trademark Usage Guidelines
in this Agreement, without the prior written approval of RadioShack.

     (c)  RadioShack  after  providing  written  notice  to a Sprint  or  Sprint
Spectrum of a breach of any trademark license  provision,  and after providing a
reasonable time to cure such breach, but not less than thirty (30) days, may, at
its option,  take those  actions  reasonably  necessary to protect  RadioShack's
trademark  rights.  Notwithstanding  the  foregoing,  a breach of these  license
provisions may give rise to  irreparable  injury;  consequently,  RadioShack may
seek  injunctive  relief  without  entering  into  any  dispute   resolution  or
arbitration process.

     (d) Control of Marks.

     (i)  Sprint  and Sprint  Spectrum  agree to adhere to the  trademark  usage
          guidelines furnished by RadioShack for the depiction of the RadioShack
          Marks ("RadioShack Trademark Usage Guidelines").  The attached Exhibit
          11(d)(ii)  will  function  as the  current  version of the  RadioShack
          Trademark Usage Guidelines.

     (ii) Sprint and Sprint  Spectrum  agree to include on all  advertising  and
          promotional   materials  bearing  any  of  the  RadioShack  Marks  the
          following notice:

               "[RadioShack  Mark] is a registered*  Trademark of  Technology
                Properties,Inc. Used under license."

          * "Registered" to be used only when the Mark is registered in the
            USPTO.

     (iii)Sprint  agrees that,  except with  respect to materials  substantially
          identical to materials that have  previously  been  approved,  it will
          furnish to RadioShack for trademark usage approval prior to any use of
          the RadioShack Marks a sample of each use of the RadioShack Marks that
          is  different  from   previously   approved   usages  on  advertising,
          promotional  materials,  packaging and labels.  Sprint agrees to amend
          the use of the RadioShack Marks in any such  advertising,  promotional
          materials,  packaging or labels if the use of the RadioShack  Marks is
          not  approved  by  Radioshack  in  accordance  with the  terms of this
          Agreement.  Sprint  will use all  commercially  reasonable  efforts to
          provide sufficient  submission lead times to allow RadioShack adequate
          review and approval  time on trademark  usage of  RadioShack  Marks by
          Sprint.  Radioshack will use all  commercially  reasonable  efforts to
          provide   trademark   usage  review  and  approval   within  the  time
          constraints  applicable to the conduct of Sprint's  operations and the
          specific advertising,  promotional,  packaging or label usage proposed
          for the RadioShack  Marks. If, however,  such approval is not received
          by Sprint  within 5 business days of the date of receipt by RadioShack
          of such  materials,  such  materials  will be deemed  approved  unless
          Sprint and RadioShack agree on a longer period of time for approval of
          specific materials. All materials will be sent for approval to:

                        General Counsel
                        Tandy Corporation
                        1800 One Tandy Center
                        Fort Worth, TX  76102

     (e) Royalties.  RadioShack provides this license royalty-free to Sprint and
Sprint Spectrum.

     (f) Rights in Marks.

     (i)  All uses of the RadioShack  Marks by Sprint and Sprint  Spectrum inure
          to the benefit of RadioShack.  Sprint and Sprint  Spectrum  acquire no
          rights,  title or interest  in the  RadioShack  Marks or the  goodwill
          associated with them, other than the right to use the RadioShack Marks
          in accordance with this Agreement. In accepting this Agreement, Sprint
          and  Sprint  Spectrum  acknowledge   RadioShack's   ownership  of  the
          RadioShack Marks, their validity and the goodwill connected with them.
          Sprint and Sprint Spectrum shall not attack the RadioShack  Marks, nor
          assist anyone in attacking them.  Sprint and Sprint  Spectrum  further
          agree not to make any  application to register the  RadioShack  Marks,
          nor to use any  confusingly  similar  trademark,  service mark,  trade
          name, or derivation,  during the term of this Agreement or thereafter.
          This paragraph will survive the termination of this Agreement.

     (ii) At the request of RadioShack,  Sprint and Sprint Spectrum will execute
          any papers or documents  reasonably necessary to protect the rights of
          RadioShack in the RadioShack  Marks and execute and deliver such other
          documents as may be reasonably requested by RadioShack.

     (g)  Infringement.   Sprint  and  Sprint  Spectrum  shall  promptly  notify
RadioShack of any  unauthorized use of the RadioShack Marks that comes to Sprint
or Sprint Spectrum's attention.  RadioShack in its sole discretion may take such
action as may be  required  to  prosecute  the  infringement.  In the event that
RadioShack  decides  that action  should be taken  against  such third  parties,
RadioShack  may take  such  action  either in its own  name,  or  alternatively,
RadioShack  may authorize  Sprint or Sprint  Spectrum to initiate such action in
Sprint or Sprint  Spectrum's  name. In either event,  Sprint and Sprint Spectrum
agree to cooperate  fully with  RadioShack to whatever extent it is necessary to
prosecute  such action,  all expenses  being borne by RadioShack and all damages
which may be recovered being solely for the account of RadioShack.

          or omission of Sprint or Sprint Spectrum, as the case may be, relating
          to claims  for  unauthorized  use or misuse  of any  RadioShack  Mark.
          Notwithstanding  the above,  Sprint and Sprint  Spectrum  shall not be
          responsible  for and  shall not  defend,  indemnify  or hold  harmless
          RadioShack from any Damages arising out of or resulting from claims of
          trademark   infringement  that  are  based  solely  on  depicting  the
          RadioShack  Marks in accordance  with the RadioShack  Trademark  Usage
          Guidelines, or pursuant to other authorization by RadioShack.

     (ii) Except  as set  forth  herein  and in  Section  18 of this  Agreement,
          RadioShack shall defend, indemnify and hold harmless Sprint and Sprint
          Spectrum,   their  subsidiaries,   offices,   agents,   employees  and

herewith; (ii) breach or default in the performance by the Indemnifying Party of
any of the  covenants  to be  performed  by the  Indemnifying  Party  under this
Agreement or any  agreement  executed by the  Indemnifying  Party in  connection
herewith; (iii) any debts, liabilities or obligations of the Indemnifying Party,
whether accrued, absolute,  contingent, or otherwise, due or to become due; (iv)
any claim by a third party preventing the Indemnifying  Party from substantially
performing its material obligations hereunder; (v) the Indemnifying Party's acts
or omissions with respect to any  advertising  (other than claims arising out of
(A) the proper use of the Indemnified Party's Marks, and (B) advertising that is
specifically  approved in form and content by the Parties, or (vi) any other act
or omission of the Indemnifying  Party, or any occurrence on the property of the
Indemnifying Party,  unrelated to this Agreement.  In addition,  notwithstanding
any term or  provision  of any  purchase  order or Addendum  to this  Agreement,
RadioShack will indemnify and hold harmless Sprint and Sprint's Indemnitees from
all Damages relating to or arising out of the manufacture,  sale or distribution
of any RadioShack-sourced,  Sprint-branded products, not attributable to any act
or omission of Sprint or otherwise  addressed herein;  and  notwithstanding  any
term or provision of any purchase  order or Addendum to this  Agreement,  Sprint
will indemnify and hold harmless  RadioShack and  RadioShack's  Indemnitees from
all Damages relating to or arising out of the manufacture,  sale or distribution
of any Sprint-sourced,  Sprint-branded  products, not attributable to any act or
omission of RadioShack or otherwise addressed herein.  PROVIDED,  HOWEVER,  that
claims,  actions and judgments  against an  Indemnitee  for wrongful or tortious
interference with contractual  relationships or wrongful or tortious  inducement
of breach of contract or like claims or actions under the case law,  statutes or
regulations  of any  jurisdiction,  and all  Damages  awarded in respect of such
claims (including any actual or punitive damages) are specifically excluded from
this indemnification obligation.

     (f) For the purposes of this  Agreement and unless  otherwise  specifically
provided,  the term "Damages"  shall include (i) all amounts  finally awarded or
charged  against an Indemnitee  and all actual  out-of-pocket  expenses or costs
incurred by such Indemnitee(s), including reasonable professional and attorneys'
fees and expenses  incurred in  investigating or in attempting to avoid the same
or oppose the imposition  thereof and (ii) interest at a rate per annum equal to
that  announced from time to time by the Wall St. Journal as the "prime rate" or
"base rate" (or the legal rate of interest,  if lower) from the date thirty (30)
days after notice of any such claim for indemnification  under this Agreement is
given,  or if an  unliquidated  claim,  from  such  later  date as the  claim is
liquidated, to the date full indemnification is made therefor, but Damages shall
not include any amounts for which any one of the Indemnitees  actually  receives
payment under an insurance policy, excluding self-insured amounts and deductible
amounts.

     (g) Promptly upon receipt by it of notice of any demand, assertion,  claim,
action or  proceeding,  judicial or otherwise,  with respect to any matter as to
which an  Indemnifying  Party has agreed to  indemnify an  Indemnitee  under the
provisions of this Agreement,  the Indemnitee will give prompt notice thereof in
writing  to  the  Indemnifying  Party,  together  with  the  statement  of  such
information  respecting such demand,  assertion,  claim, action or proceeding as
the Indemnitee  shall then have. If the  Indemnifying  Party  acknowledges  full
liability or potential  liability  without  admitting same under this Agreement,
the  Indemnifying  Party  shall  have the  right to  contest  and  defend by all
appropriate legal or other proceedings any demand,  assertion,  claim, action or
proceeding  with  respect  to which it has been  called  upon to  indemnify  the
Indemnitee under the provisions of this Agreement; provided, however, that:

     (i)  notice of intention so to contest shall be delivered to the Indemnitee
          within twenty (20) calendar days from the receipt by the  Indemnifying
          Party of notice of the  assertion  of such demand,  assertion,  claim,
          action or proceeding;

     (ii) the Indemnifying Party will pay all costs and expenses of such contest
          or defense,  including all attorneys' and  accountants'  fees, and the
          cost of any bond required by law to be posted in connection  with such
          contest or defense;

     (iii)such contest or defense  shall be  conducted  by  reputable  attorneys
          employed  by the  Indemnifying  Party and  reasonably  approved by the
          Indemnitee, at the Indemnifying Party's sole cost and expense, but the
          Indemnitee shall have the right to participate in such proceedings and
          to  be  represented   by  attorneys  of  its  own  choosing,   at  the
          Indemnitee's cost and expense without  contribution or indemnification
          by the Indemnifying Party for such costs or expenses;

     (iv) if after such  opportunity,  the Indemnifying  Party does not elect to
          assume the defense in any such  proceedings,  the  Indemnifying  Party
          shall be bound by the results  obtained by the  Indemnitee,  including
          without limitation any out-of-court settlement or compromise;

     (v)  if the Indemnifying Party assumes the defense,  the Indemnitee(s) will
          not settle, or attempt to settle,  such claim without the Indemnifying
          Party's consent; and


     (vi) the  Indemnifying  Party will not settle any claim  without  the prior
          written consent of the Indemnitees,  unless the settlement  contains a
          complete  and  unconditional  release  of the  Indemnitee(s),  and the
          settlement does not involve the imposition of any  nonmonetary  relief
          on the Indemnitees.

     (h)  Remedies in General - No delay or omission on the part of any Party in
exercising any right or remedy shall operate as a waiver of said right or remedy
or any  other  right  or  remedy.  A waiver  on any one  occasion  shall  not be
construed  as a bar to or a waiver of any right on any  future  occasion.  Every
right and remedy of a Party shall be  cumulative  and in addition to every other
right and remedy  expressed in this  Agreement or allowed by law or equity,  and
may be exercised singularly or concurrently.

15. Publicity - Except for legally mandated  disclosures,  any press releases or
public  announcements  relating to this  Agreement or the terms of the Agreement
must be mutually agreed upon by the Parties.

16. Independent Contractors - Nothing contained in this Agreement is intended or
shall be construed to create or establish any agency, partnership, joint venture
or  other   profit-sharing   arrangement,   landlord-tenant,   or  lessor-lessee
relationship between the Parties. No Party shall have any authority,  express or
implied, to create or assume any obligation,  enter into any agreement, make any
representation  or warranty,  file any document with any  governmental  body, or
serve or accept legal process on behalf of any other Party,  settle any claim by
or against  any other  Party,  or to bind or  otherwise  render any other  Party
liable in any way to any other person, without the prior express written consent
of the Party to be affected by such action.

17.  Product and Service  Representations  - All Product and Service  warranties
will be limited to, and be as set forth,  on each respective  Addendum  attached
hereto.  RadioShack  will not make to any  customer or  potential  customer  any
representation or warranties  whatsoever on behalf of Sprint or Sprint Spectrum,
and  shall  effectively   disclaim  any  authority  to  make  such  warranty  or
representation  on  Sprint's or Sprint  Spectrum's  behalf,  to any  customer or
potential  customer  regarding  any of  the  Products  or  Services,  except  as
specifically  authorized  by Sprint or Sprint  Spectrum on an Addendum  attached
hereto, as appropriate.

     Sprint and  Sprint  Spectrum  will not make to any  customer  or  potential
customer any representation or warranty whatsoever on behalf of RadioShack,  and
shall effectively disclaim any authority to make such warranty or representation
on RadioShack's  behalf, to any customer or potential  customer regarding any of
the Products or Services,  except as specifically authorized by RadioShack on an
Addendum attached hereto, as appropriate.

18.  Limitation of Liability - IN NO EVENT WILL ANY PARTY BE LIABLE TO THE OTHER
PARTIES FOR SPECIAL, INDIRECT, INCIDENTAL,  EXEMPLARY,  CONSEQUENTIAL,  PUNITIVE
DAMAGES, OR LIKE DAMAGES,  HOWEVER CALLED, OR LOSS OF PROFITS,  ARISING FROM THE
RELATIONSHIP  OF THE PARTIES OR THE CONDUCT OF BUSINESS UNDER, OR BREACH OF THIS
AGREEMENT,  EXCEPT  WHERE SUCH  DAMAGES,  OR LOSS OF PROFITS,  ARE CLAIMED BY OR
AWARDED  TO A THIRD  PARTY IN A CLAIM OR  ACTION  AGAINST  WHICH A PARTY TO THIS
AGREEMENT  HAS  A  SPECIFIC  OBLIGATION  TO  INDEMNIFY  ANOTHER  PARTY  TO  THIS
AGREEMENT.

     NOTWITHSTANDING ANY INDICATION TO THE CONTRARY HEREIN, IN NO EVENT WILL ANY
PARTY,  INCLUDING  SPRINT AND SPRINT  SPECTRUM,  BE LIABLE OR HAVE ANY JOINT AND
SEVERAL OBLIGATION FOR THE INDEMNIFICATION OBLIGATIONS, OR ANY OTHER OBLIGATIONS
OR LIABILITIES,  OF ANY OTHER PARTY UNDER THIS AGREEMENT OR ANY ADDENDUM HERETO.
THIS  COVENANT DOES NOT AFFECT THE  OBLIGATION  OF A PARTY TO INDEMNIFY  ANOTHER
PARTY AS SPECIFICALLY PROVIDED HEREIN.

19.  Termination

     (a)  Termination  Events.  No Party will have the right to  terminate  this
Agreement for a period of thirty-six (36) months after the Effective Date unless
the grounds for termination are:

     (i)  that  another  Party has been  convicted  of a violation of a Federal,
          state or local  criminal  statute  and such  conviction  actually  and
          materially  adversely  affects  that  Party's  ability to perform  its
          obligations under this Agreement;

     (ii) that a final judgment has been entered  against  another Party finding
          said  Party in  violation  of a  Federal,  state or local  statute  or
          regulation  and such final judgment  actually and  materially  affects
          that Party's ability to perform its obligations under this Agreement;

     (iii)that another Party has (a) filed a voluntary petition in bankruptcy or
          voluntary petition or an answer seeking  reorganization,  arrangement,
          readjustment  of its  debts,  or any other  relief  under the  Federal
          Bankruptcy  Code  or  under  any  other  insolvency  act or law now or
          hereafter  existing,  (b) made a general assignment for the benefit of
          creditors,  or (c) admitted in writing its  inability to pay its debts
          as they mature;

     (iv) that another Party has had (a) an  involuntary  petition filed against
          it seeking reorganization,  arrangement, readjustment of its debts, or
          any other relief under the Federal  Bankruptcy Code or under any other
          insolvency  act or law now or  hereafter  existing  (b) a receiver  or
          trustee  appointed  involuntarily,  and such petition or action is not
          suspended,  stayed or dismissed within sixty (60) days after filing or
          appointment, as the case may be.

     (v)  that a Final  Order has been  issued by the  Arbitrator  containing  a
          finding of a material breach of contract,  representation  or warranty
          given by a Party in this Agreement or of any other material  breach of
          this Agreement by the Party against which termination is sought; or

     (vi) that a Change of Control has occurred  involving a Party, other than a
          transaction  constituting  a Change of Control by one Party of another
          Party.

     With respect to a termination  pursuant to  subsections  (i)-(iv) the Party
seeking  termination  will  provide the other  Parties  sixty (60) days  written
notice   following  the  occurrence  of  the  event  creating  the  grounds  for
termination; and, with respect to a termination pursuant to subsection (vi), the

immediate  termination  following  receipt of the Final  Order,  but in no event
sooner than sixty (60) days from the date a Party first  notifies  the others in
writing of a breach.

     (b) Intentionally left blank.

     (c)  Termination  after  Thirty-Six  Months.  Each  Party may  unilaterally
terminate  this Agreement at any time after the end of the  thirty-sixth  (36th)
month after the Effective Date upon one hundred eighty (180) days written notice
following the unsatisfactory  conclusion of the Dispute Resolution procedure set
forth in Section 20(a) below. The Parties may by mutual agreement terminate this
Agreement at any time after the end of the  thirty-sixty  (36th) month after the
Effective Date by the following procedure:

     (i)  A Party  who  desires  to  initiate  the  mutual  termination  process
          described  herein (the  "Initiating  Party")  shall  notify each other
          Party  to  this  Agreement  (each a  "Responding  Party")  in  writing
          pursuant  to Section 26 and signed by the Chief  Executive  Officer of
          the Initiating Party. Such notice shall state conspicuously that it is
          a "Notice of Request for Mutual  Termination of Master Agreement." The
          Notice of  Request  for Mutual  Termination  may be  withdrawn  by the
          Initiating  Party if the  Initiating  Party  notifies each  Responding
          Party of such withdrawal in writing signed by the said Chief Executive
          Officer prior to receiving the appropriate  written responses from all
          Responding Parties described below.

     (ii) Within thirty (30) days from receipt of a Notice of Request for Mutual
          Termination  from the Initiating  Party or within such extended period
          as may be agreed upon by all Parties in writing, each Responding Party
          shall respond in writing signed by its Chief Executive  Officer to the
          Initiating  Party  and  send  a  copy  of its  response  to the  other
          Responding Party. The content of such responses shall only state:

     a.   "Notice  of Request  for Mutual  Termination  of Master  Agreement  by
          (Party Name)" (if the  Responding  Party  concurs with the  Initiating
          Party and wishes to mutually terminate the Master Agreement); or

     b.   "Rejection of Request for Mutual  Termination  of Master  Agreement by
          (Party Name)" (if Responding Party does not concur with the Initiating
          Party and does not wish to mutually terminate the Master Agreement).

     Each Responding party shall use its best efforts to respond within the time
period  provided.  Failure of any  Responding  Party to respond  within the time
period  shall be deemed an  automatic  withdrawal  of all Notices of Request for
Mutual  Termination  of the Master  Agreement  by the  Initiating  Party and all
Responding Parties.

     (iii)If all  parties  send  the  required  Notice  of  Request  for  Mutual
          Termination  of the Master  Agreement as set forth above,  the Parties
          shall, within the next thirty (30) days or within such extended period
          as may be agreed by all Parties in writing, negotiate to determine and
          resolve all  outstanding  issues,  including all amounts payable under
          Section  20(b)(iii)  and all other  amounts  payable by a Party to the
          other  Parties.  Any such  outstanding  issues  that are not  resolved
          within the time  provided  will be  submitted  to  arbitration  in the
          manner set forth in this Agreement.

     (d) Termination  Applies to All Parties. If this Agreement is terminated by
a Party, this Agreement will be terminated in its entirety.

     (e) Mitigation of Losses.  Upon the occurrence of an event creating grounds
for termination under Section 19(a) above, including but not limited to, a claim
that any Party has breached  this  Agreement or any  representation  or warranty
given in this Agreement,  the Parties shall use commercially  reasonable efforts
to mitigate damages caused by the occurrence of such event.

     (f) Duties Upon  Termination.  Upon the  expiration or  termination of this
Agreement:

     (i)  Except  as  otherwise  provided  herein,  the  Parties  will  use  all
          commercially  reasonable  efforts  to cease  immediately  all of their
          respective  efforts to promote the sale of the  Products  and Services
          through the Retail Stores  including the use of the Combination  Marks
          but in any event no later than sixty  (60) days  after  expiration  or
          termination of this Agreement;

     (ii) Except as otherwise provided herein, RadioShack will cease immediately
          the use of any Sprint and/or  Sprint  Spectrum  Marks,  and Sprint and
          Sprint Spectrum will cease  immediately  the use of RadioShack  Marks,
          and each will cease immediately the use of the Combination Marks;

     (iii)Except as otherwise  provided  herein,  the Parties  will  discontinue
          immediately  making any  statements  or taking any actions  that might
          cause third parties to infer that any business relationship  continues
          to exist  between the Parties  pursuant to this  Agreement,  and where
          necessary  or  advisable,  inform  third  parties  that the Parties no
          longer have a business relationship pursuant to this Agreement; and

     (iv) RadioShack   will  retain   possession   of  and  take  title  to  the
          Merchandising  Display (if neither Sprint or Sprint Spectrum  notifies
          RadioShack  within  thirty  (30)  days  after  the  effective  date of
          termination   of  such   Party's   intent  to  take  and   remove  the
          Merchandising  Display at such Party's  expense),  and RadioShack will
          remove and destroy the Sprint and/or Sprint  Spectrum  Marks and other
          designations  from all  Retail  Stores,  including  the  Merchandising
          Displays,  at  RadioShack's  sole cost and expense,  within sixty (60)
          days following termination of this Agreement.

     Notwithstanding anything to the contrary herein, following a termination of
this  Agreement,  RadioShack may continue to advertise and sell the Products for
the time period necessary to sell through or sell out each Product  remaining in
current  inventories to the extent provided in each Addendum hereto,  but in any
event no later than  twenty-four  (24) months after expiration or termination of
this  Agreement.  During such time,  RadioShack  may  continue to use the Sprint
Marks (but not in Combination Mark Format), but such use shall be subject to the
terms of this Agreement and limited to the Products  RadioShack has on order and
in inventory as of the termination of this Agreement.

     (g)  Subsequent  Marketing.  During the term of this  Agreement,  and for a
period  equal  to the  greater  (i) five  years  following  termination  of this
Agreement,  or (ii) the time period set forth in any applicable governmental law
or  regulations,  RadioShack  will not  sort  out and use for its own  purposes,
including any target  marketing,  a list of customers who have  purchased any of
the Sprint or Sprint Spectrum Products or Services which are the subject of this
Agreement,  or make such list or any portion thereof available to another PCS or
telecommunications  carrier  for the  purpose of sale of  products  or  services
similar to those set forth on any Addendum attached hereto;  provided,  however,
that this  paragraph  shall not be construed in any way to limit  general use by
RadioShack  of  RadioShack's  lists  compiled by RadioShack of its own customers
purchasing products or services, including Products or Services.

     (h) Post Termination Compensation.  For a period of twenty-four (24) months
following the  expiration or termination  of this  Agreement,  Sprint and Sprint
Spectrum shall pay RadioShack residual  commissions and compensation at the rate
and pursuant to the terms set forth on the applicable  Addendum in effect on the
effective date of termination or expiration of this Agreement.

     Upon a unilateral termination of this Agreement, Sprint or Sprint Spectrum,
as the  case  may be,  has the  option  in  Sprint  or  Sprint  Spectrum's  sole
discretion,  but not the  obligation,  to pay to  RadioShack,  in one lump  sum,
within  sixty  (60) days  after the  termination  date,  an amount  equal to the
present value as of the effective date of (using a discount  factor equal to the
then current two year  Federal  T-Bill  interest  rate per annum) of a stream of
Assumed  Payments,  as  defined  below)  for 24 months,  less  payments  made to
RadioShack  between the date of termination  and the date of payment of the lump
sum in full satisfaction of their respective obligations, as the case may be, to
pay residual  commissions  hereunder.  For the purposes of this option, the lump
sum payment  will be equal to the  Assumed  Payment  multiplied  by 24, and then
discounted  at the rate set forth  above.  For the  purposes of this  Agreement,
"Assumed  Payment"  means the amount equal to 1/12th of the  residuals  actually
earned by RadioShack  from all Sprint or Sprint Spectrum  Services,  as the case
may be,  sold on a residual  basis by  RadioShack  on behalf of Sprint or Sprint
Spectrum during the twelve (12) month period immediately preceding a termination
of this Agreement.  Any bounties,  activation fees,  incentive program payments,
marketing development funds,  advertising funds or any other non-residual or one
time  payments  made by Sprint  or Sprint  Spectrum  to  RadioShack  will not be
included  in this  calculation.  If the  Agreement  is in effect  for fewer than
twelve (12) months prior to termination,  the monthly average will be multiplied
by twelve in order to arrive at the twelve month period.

20.   Dispute Resolution

     (a)  Procedures  - In the event of a  dispute  arising  between  any of the
Parties,  out  of or  relating  to  the  Agreement  or  the  performance  of any
obligations under the Agreement, the Parties agree to attempt, in good faith, to
resolve such disputes through the escalation procedure set forth below:

     (i)  The Joint  Steering  Committee  members for the Parties  shall meet by
          telephone  or in person and  attempt to  resolve  any  dispute in good
          faith;

     (ii) If the Joint  Steering  Committee  members  are unable to resolve  the
          dispute  within five (5) business  days, or such longer period of time
          as agreed by the Joint  Steering  Committee,  the Parties'  respective
          Joint Steering  Committee  members shall provide a written  summary of
          the disputed issues to a senior division  officers for each Party. The
          senior division  officers (i.e., the president or titular head of each
          appropriate division or designated group of such Party) for each Party
          shall then meet by  telephone or in person and attempt to resolve such
          dispute in good faith;

     (iii)If the senior  division  officers  are unable to resolve  the  dispute
          within ten (10)  business  days,  the senior  division  officers  will
          provide  a  written  summary  of the  disputed  issues  to  the  chief
          executive officers of each Party. The chief executive officers of each
          Party will then meet by  telephone or in person and attempt to resolve
          such dispute in good faith;

     (iv) If the chief  executive  officers  are unable to resolve  the  dispute
          within ten (10) business  days,  then either Party may terminate  this
          Agreement as provided in Section 19(a)(v) or 19(c) above.

     (b) Termination Payments and Arbitration.

     (i)  Upon a unilateral  termination of this  Agreement by RadioShack  under
          Section  19(c),  or by Sprint or Sprint  Spectrum under Section 19(a),
          RadioShack  will pay to Sprint and Sprint  Spectrum an amount equal to
          the unamortized  Merchandising  Display Expenditures (less any credits
          or payments for the same  previously  received) as of the  termination
          date of this  Agreement,  and Radio  Shack will be entitled to receive
          only  one-half  of the amount  otherwise  payable by Sprint and Sprint
          Spectrum under Section 19(h) above;

     (ii) Upon a unilateral  termination  of this  Agreement by Sprint or Sprint
          Spectrum  under Section 19(c),  or by RadioShack  under Section 19(a),
          RadioShack  will pay to Sprint and Sprint  Spectrum an amount equal to
          one-half of the unamortized  Merchandising  Display Expenditures (less
          any credits or payments  for the same  previously  received) as of the
          termination date of this Agreement, and RadioShack will be entitled to
          receive all of the amounts otherwise payable under Section 19(h).

     (iii)Upon a mutual  termination  of this  Agreement  by the  Parties  under
          Section 19(c),  the Parties will meet and agree upon the amount of the
          unamortized  Merchandising  Display  Expenditures,  if any, payable to
          Sprint  and  Sprint  Spectrum  by Radio  Shack and the amount of money
          otherwise  payable under Section 19 (h), if any, payable to RadioShack
          by  Sprint  and  Sprint  Spectrum.   taking  into   consideration  the
          principles set forth in Section 20(b)(i) and Section 20(b)(ii).

     (iv) All  payments  due  under  this  Section  will be due and  payable  in
          immediately  available  funds within thirty (30) days of the effective
          date of the  termination  of  this  Agreement.  If  Sprint  or  Sprint
          Spectrum,  as the case may be,  elect the lump sum  payment  option in
          Section 19(h) above,  the lump sum payment will be offset  against the
          payment payable by Radio Shack hereunder.

     (v)  Solely for the purposes of this Section 20(b), and notwithstanding any
          inconsistent  period of amortization or depreciation  schedule claimed
          or used by a Party hereto, the Merchandising Display Expenditures will
          be  amortized  as  follows:  the  Merchandising  Display  Expenditures
          attributable  to the fixtures  will be amortized on the  straight-line
          basis  over  one  hundred  (100)  months;  and  Merchandising  Display
          Expenditures  attributable to the computer interface will be amortized
          on the straight-line  basis over thirty-six (36) months.  The starting
          date for the amortization with respect to each computer  interface and
          fixtures  for each  Retail  Store  will be the  first day of the first
          month in which a Merchandising Display is installed and operational in
          that Retail Store.

     Except for termination  payment  disputes under Section  20(b)(i) and (ii),
the Parties will submit to an Arbitrator any dispute which cannot be resolved by
the Parties  regarding the unwinding of this relationship and any alleged breach
of contract issues.  The Arbitrator will determine what, if any, measures should
be taken by the Parties to unwind the relationship;  provided, however, that the
Parties will not submit any trademark license provision to arbitration.

     Irrespective of termination, following the dispute resolution procedure set
forth above, a Party may submit a good faith  allegation of a breach of contract
claim to the  Arbitrator  for  determination  by the  Arbitrator,  who will also
determine the amount of damages,  if any, to be paid by a Party to another Party
for a breach of this Agreement.  This Arbitration  process shall be conducted in
accordance with the procedures set forth on Schedule 20(b) attached hereto.

21.  Confidentiality

     (a) Restriction - All Proprietary Information disclosed by one Party to the
other Parties is deemed to be  confidential,  restricted and  proprietary to the
disclosing Party.

     (b) Use - The Parties  agree to use the  Proprietary  Information  received
from the other Parties only to accomplish the intent of this Agreement. No other
rights to trademarks, inventions, copyrights, patents, or any other intellectual
property  rights are implied or granted under this Agreement or by the conveying
of Proprietary Information between the Parties.  Notwithstanding anything to the
contrary  herein or in the  Confidentiality  Agreement,  either Party may attach
this Agreement and attachments hereto to any public filing to the extent counsel
for such Party reasonably determines necessary.

     (c) Copying - Proprietary  Information  supplied is not to be reproduced in
any form  except  as  required  to  perform  a Party's  obligations  under  this
Agreement.

     (d) Care - The  receiving  Parties  must provide the same degree of care to
avoid  disclosure or  unauthorized  use of the  Proprietary  Information as they
provide to protect their own similar  proprietary  information.  All Proprietary
Information  must be retained by the  receiving  Parties in a secure  place with
access  limited  to only such of the  receiving  Party's  employees,  attorneys,
accountants  or agents  who need to know such  information  to perform a Party's
obligations  under this  Agreement and to such third  parties as the  disclosing
Party has consented to by prior written approval.

     (e) Ownership - All Proprietary Information,  unless otherwise specified in
writing,  (a) remains the property of the disclosing  Party, (b) must be used by
the receiving  Parties only for the purpose of performing its obligations  under
this Agreement,  and (c) such Proprietary  Information,  including all copies of
such  information,  must be returned to the disclosing  Party or destroyed after
the receiving  Party's need for it has expired or upon request of the disclosing
Party, and, in any event, upon termination of this Agreement.  At the request of
the  disclosing  Party,  the receiving  Party will furnish a  certificate  of an
officer of the receiving  Party  certifying  that  Proprietary  Information  not
returned to disclosing Party has been destroyed.

     (f) Limitation - The Parties agree that the term "Proprietary  Information"
does not include information which:

     (i)  has been or may in the  future  be  published  or is now or may in the
          future be  otherwise  in the  public  domain  through  no fault of the
          receiving Party;

     (ii) prior to disclosure  pursuant to this Agreement is property within the
          legitimate possession of the receiving Party;

     (iii)subsequent  to  disclosure  pursuant  to this  Agreement  is  lawfully
          received from a third party having rights in the  information  without
          restriction of the third party's right to disseminate  the information
          and without notice of any restriction against its further disclosure;

     (iv) is independently  developed by the receiving Party through parties who
          have not had, either directly or indirectly, access to or knowledge of
          such Proprietary Information; or

     (v)  is  obligated  to be  produced  under  order of a court  of  competent
          jurisdiction or other similar requirement of a governmental agency, so
          long as the Party  required to disclose the  information  provides the
          other Party with prior notice of such order or requirement.

     (g) Relief - The  Parties  agree that a breach of this  Section 21 may give
rise to  irreparable  injury  to the  non-breaching  Party(ies)  that  cannot be
compensated for adequately by damages. Consequently, the Parties agree that each
Party  shall be  entitled,  in  addition  to all other  remedies  available,  to
injunctive and other equitable  relief to prevent a breach of this Section 21 of
this  Agreement and to secure the  enforcement of the provisions of this Section
21 in any court of  competent  jurisdiction  in the  United  States or any state
thereof (and the Parties agree to waive any  requirement for the posting of bond
in connection with such remedy).

     (h) Term - A Party must not  disclose  the  Proprietary  Information  for a
period which is the longer of (a) four years from the date of  disclosure or (b)
two years following the date of termination of this Agreement.

22.      Insurance

     (a) Required Insurance - Each Party must, during the term of this Agreement
and at its sole expense, obtain and keep in force, the following insurance:

     (i)  Commercial  General  Liability  Coverage,  including  personal injury,
          bodily  injury,  property  damage,   operations  hazard,   independent
          contractor coverage, contractual liability, and products and completed
          operations  liability,  in limits  not less than  $5,000,000  for each
          occurrence (combined single limit); and

     (ii) Worker's Compensation and Employer's Liability insurance.

     (b)  Request  for  Certificates  - Each Party  shall  promptly  comply with
another Party's request for a certificate of insurance evidencing such coverage.

     (c) Policies of Insurance - All required  insurance  policies must be taken
out with  reputable  national  insurers  that are licensed to do business in the
jurisdictions where the Parties are doing business.

     (d) No  Limitation  On Liability - The  provision of insurance  required in
this Agreement will not be construed to limit or otherwise  affect the liability
of any Party to the other Parties.

     (e) Release - The Parties agree to release each other, and their respective
principals, employees, representatives and agents, from any claims for damage to
any  person or  property,  that are  caused by, or result  from,  risks  insured
against under any insurance  policies carried by the Parties and in force at the
time of any such damage. Each Party will cause each insurance policy obtained by
it to provide that the insurance  company waives all right of recovery by way of
subrogation against the other Party in connection with any damage covered by any
such policy.  Neither Party will be liable to the other for any damage caused by
fire or any of the risks insured against under any insurance  policy required by
this Section.

23.  Ethical  Conduct  and  Related  Covenants  - Each  Party will  perform  its
obligations  under  this  Agreement,   in  a  diligent,   legal,   ethical,  and
professional manner. Any representation made by either Party concerning Products
or Services  shall be in  compliance  with the  covenants in of this  Agreement.
Neither Party will disparage the other Party,  or the other Party's  products or
services.

24.  Compensation Disputes and Audit

     (a)  Disputes  Concerning  Compensation  Payments - If any  dispute  arises
concerning any compensation payment due hereunder, the disputing Party must give
the other Parties  written notice of the nature and amount of the dispute within
ninety (90) days of receipt of payment and supporting documentation.  If a Party
does not receive such  written  notice  within that ninety (90) day period,  all
compensation  payments  made  will  be  final  and  the  other  Parties  may not
thereafter  dispute  the  nature  or  amount of the  compensation  payment.  If,
however, the complaining party did not have knowledge of the compensation due it
because of fraud,  intentional failure to disclose,  breach of this Agreement or
any other act or omission of the other Party, this provision shall not apply and
the complaining Party shall have two (2) years from the date of discovery of the
relevant facts in which to make a claim.

     (b) Audit - Each Party  will  maintain  complete  and  accurate  accounting
records during the term of this  Agreement and for twelve (12) months  following
conclusion  or  expiration  of all  post-agreement  payment  obligations  of all
Parties in a consistent  form to substantiate  the direct monetary  payments and
reporting obligations of one Party to any other Party under this Agreement. Each
Party may, upon reasonable  advanced  written  notice,  conduct during the other
Party's  regular  business  hours,  and in accordance  with  applicable  law and
reasonable  security  requirements,  audits of such direct monetary  payment and
reporting  obligation  accounts and records,  in  accordance  with the following
guidelines  and  restrictions:  (a) the audit may be conducted by members of the
internal  audit  department  who are  employees of the auditing  Party,  (b) the
audited Party may require the auditing  Party's employee to conduct the audit on
the premises of the audited Party,  (c) the audited Party will have the right to
have an employee or  representative  present at all times during the audit,  (d)
the  auditing  Party will not have  direct  unrestricted  access to the  audited
Party's computer  database without the consent of the audited Party, and will be
entitled to review only those  specific  records of the audited  Party  directly
related to the  monetary  obligations  of the  audited  Party  hereunder  or the
applicable   Addendum,    specifically   limited   to   customer    activations,
deactivations,  customer billing records,  records related to  media/advertising
expenditures  (excluding  advertising  rate  information  subject to third party
confidentiality   and   non-disclosure   agreements),    Merchandising   Display
Expenditures and reimbursements,  market launch expenditures, market development
funds/escrow  arrangements,  and  any  other  records  directly  related  to the
monetary  rights and obligations of such Party  hereunder,  and (e) the auditing
Party's audit of activation,  deactivation, and customer billing records will be
limited to a reasonable random sampling audit of those records.

     Subject to the  restrictions  set forth  above,  the  audited  Party  shall
cooperate fully with the auditing Party.  All reasonable fees and costs incurred
(including a  reasonable  charge for the services of any employee of the audited
Party  directly  involved in the audit) by either Party in connection  with such
audits  shall be paid by the  auditing  Party.  The audited  Party will have the
right to have the  results of any such audit  reviewed  by the  audited  Party's
internal  auditing staff or by the audited Party's  independent  accountants who
then  audit  the  financial   statements  of  the  audited  Party  ("Independent
Auditors").  The cost of such internal or Independent  Auditors  review shall be
borne by the  audited  Party.  The  audited  Party  shall  use its  commercially
reasonable   efforts  to  immediately   correct  any  deficiencies   related  to
performance uncovered by such audit.

     Each Party may seek an audit of the other Party,  pursuant to this Section,
no more than once every six (6) months.  These audit rights shall  survive until
the period ending twelve (12) months  following  conclusion or expiration of all
post-agreement payment obligations of all Parties under this Agreement.

     27.  Assignment - The Parties shall not assign or in any other way transfer
this Agreement or any right or obligation hereunder, whether by operation of law
or otherwise,  without the prior  written  consent of the other  Parties,  which
consent shall not unreasonably be withheld or delayed;  provided,  however, such
consent  shall not be  required  in the event this  Agreement,  or any rights or
obligations  hereunder,  is assigned by a Party:  (i) to a person or entity with
which that Party may merge or  consolidate,  or (ii) to a person or entity which
purchases all or substantially  all of that Party's business or assets, or (iii)
to a person or entity which is an Affiliate of that Party.

28.      Miscellaneous Provisions

     (a) Force Majeure.  Any Party's delay in, or failure of,  performance under
this Agreement  shall be excused where such delay or failure is caused by an act
of nature,  fire,  or other  catastrophe,  electrical,  computer  or  mechanical
failure,  work  stoppage,  delays or  failure  to act of any  carrier  or agent,
direction or effect of an order from a court or  government  agency or body,  or
any other cause beyond a Party's direct control. Any Party seeking to be excused
for a delay in  performing  any  obligation  due to force  majeure must exercise
reasonable efforts to minimize the delay in performing such obligation.

     (b) Entire  Agreement.  This  Agreement,  together  with the Addenda to the
Agreement, set forth the entire understanding of the Parties with respect to the
subject matters contained  therein,  and supersede any prior or  contemporaneous
agreements, understandings and representations, whether oral or written, made by
or among the Parties  hereto.  No supplement,  modification or amendment of this
Agreement shall be binding, unless executed in writing by the Parties hereto.

     (c)  Amendments.  Any  amendments to the  Agreement  must be in writing and
signed by the Parties.

     (d) Waiver. If any Party fails, at any time, to enforce any right or remedy
available to it under this Agreement,  that failure shall not be construed to be
a waiver of the right or remedy with  respect to any other  breach or failure by
the other Party.

     (e) Validity.  If for any reason any clause or provision of this Agreement,
or the application of any such clause or provision in a particular context or to
a particular situation,  circumstance,  or person, should be held unenforceable,
invalid  or in  violation  of law by any  court  or  other  tribunal,  then  the
application   of  such  clause  or  provision  in  contexts  or  to  situations,
circumstances   or  persons   other  than  that  in  or  to  which  it  is  held
unenforceable, invalid or in violation of law shall not be affected thereby, and
the remaining  clauses and provisions hereof shall  nevertheless  remain in full
force and  effect.  Further,  where  state or federal  law governs any aspect of
matters or services  covered by this Agreement,  such state or federal law shall
prevail over inconsistent provisions in this Agreement.

     (f) Choice of Law.  This  Agreement  shall be governed by and  construed in
accordance  with  the laws of the  State  of  Delaware,  without  regard  to its
principles of conflicts of law.

     (g) Captions. The captions included in this Agreement have been inserted as
a matter of convenience  only and in no way are intended to define,  limit or to
be used in connection with the interpretation of this Agreement.

     (h) Approvals.  This Agreement is subject to any necessary  approval and/or
modification required by any local, state and federal regulatory agencies having
jurisdiction over the subject matter hereof.

     (i) Unforeseen  Expenses.  The Parties shall address any future  unforeseen
mutual Program  expenses which result in a significant  financial  impact on the
Program in such a way as to not disadvantage one or the other.

     (j)  Nonrecourse.  Unless a Party to this  Agreement,  no past,  present or
future  shareholder,  limited or general  partner in or of  RadioShack or Sprint
Spectrum,  no parent or other Affiliate of any company comprising RadioShack and
no parent or other affiliate of any company  comprising Sprint Spectrum,  and no
shareholder,   officer,  employee,  servant,   executive,   director,  agent  or
authorized  representative  of any of them (each, an "Operative") will be liable
by virtue of the direct or indirect ownership interest of such Operative in such
Party for  payments  due under  this  Agreement  or for the  performance  of any
obligation,  or breach of any  representation  or  warranty  made by such  Party
hereunder.  The sole recourse of RadioShack or Sprint Spectrum for  satisfaction
of the obligations of Sprint Spectrum or RadioShack under this Agreement will be
against the Party and the Party's  assets and not against any  Operative  or any
assets or property of any such Operative.  In the event that a default occurs in
connection  with such  obligations,  no action will be brought  against any such
Operative by virtue of its direct or indirect  ownership  interest in RadioShack
or Sprint Spectrum, as the case may be.

     (k)  Counterparts.  This  Agreement  may  be  executed  in  any  number  of
counterparts, all of which when taken together shall constitute one and the same
instrument.  Any Party  hereto may execute  this  Agreement  by signing any such
counterpart.

                                 Schedule 20(b)

                             ARBITRATION PROCEDURES

1.       Controversies and Claims Subject to Arbitration.

     Any  controversy  arising  out of or  related  to the  relationship  of the
Parties,  (excluding the  determination  of  termination  payments under Section
20(b)(i),  (ii) or a good  faith  allegation  of a  breach  of the  terms of the
Agreement or other matters for which arbitration is specifically provided in the
Agreement  (collectively,  "Claims"),  will be settled by a single Arbitrator in
accordance with the arbitration rules of the American  Arbitration  Association,
governed by the United States  Arbitration  Act, 9 U.S.C.  Sec. 1., et. seq. The
Arbitrator  shall apply the common law of Delaware with respect to any breach of
contract claims.  If the Parties cannot agree on the selection of the Arbitrator
within ten (10) days of the request for  arbitration,  any Party may immediately
request the  appointment  of the  Arbitrator  in  accordance  with the governing
rules.  Arbitration  shall  occur at any  location  to which the Parties and the
Arbitrator agrees or, in the absence of agreement, in Oklahoma City, Oklahoma.

2.       When Arbitration May Be Demanded.

     Demand for arbitration may not be made until the later of the expiration of
any  period  for  notice  and time to cure,  or the tenth  (10th)  day after the
Parties  have  presented  evidence  to each other or have been given  reasonable
opportunity to do so, with respect to their position regarding their Claims.

     A demand for  arbitration  shall be made within a reasonable time after the
Parties have exchanged  their  position,  and in no event shall it be made after
the date when institution of legal or equitable proceedings based on a breach of
contract would be barred by the applicable statute of limitations.

3.       Factors for Consideration.

     Each  Party  may  propose  in  writing,  within  fifteen  (15)  days of the
selection of an Arbitrator,  those factors that it contends should be applied by
the Arbitrator in reaching a decision, and may submit a supporting brief.

     The Parties may,  within twenty (20) days  following the  conclusion of the
discovery provided for in Section 6 below,  propose additional factors that they
contend should be applied by the Arbitrator and may submit supporting briefs.

     The  Arbitrator  shall receive  evidence and hear  arguments on each factor
proposed as hereinbefore  provided  ("proposed  factor(s)"),  for inclusion as a
factor to be applied in reaching a decision.  The  Arbitrator  shall  select for
application any proposed factor if there is sufficient information in the record
as a whole to permit its rational application.  In applying the proposed factors
selected,  the Arbitrator may weigh the proposed  factors,  including  giving no
weight,  to any one or more proposed  factors.  The Arbitrator  also shall apply
each proposed  factor  consistently  to the maximum extent  possible,  provided,
however,  that the  Arbitrator  may not decline to apply a proposed  factor to a
Party  solely  because  information  in the  record as a whole  concerning  that
proposed  factor may not apply to, or is  insufficient  to allow  application of
that proposed factor to, all Parties.  The Arbitrator  shall apply only proposed
factors.  The  Arbitrator  shall,  in his final  order,  an  explanation  of the
reason(s) why any proposed  factor was or was not applied,  and if applied,  the
manner in which it was applied.

4.       Contract Performance During Arbitration.

     During arbitration proceedings,  the Parties will continue to perform their
respective  responsibilities under the terms and conditions of the Agreement and
each Addendum thereto.

5.       Claims and Timely Assertion of Claims.

     A Party who  files  notice of demand  for  arbitration  must  assert in the
demand all Claims then known to that Party on which  arbitration is permitted to
be  demanded.  When  a  Party  fails  to  include  a  claim  through  oversight,
inadvertence or excusable neglect,  or when a claim has matured or been acquired
subsequently, the Arbitrator may permit amendment.

6.       Discovery.

     Within  thirty  (30) days of  appointment,  the  Arbitrator  shall  prepare
written  information  and  document  requests  to the Parties for the purpose of
eliciting  the  facts  necessary  to  make a  decision.  The  Parties  may  make
suggestions by letter to the Arbitrator as to the information and documents they
deem  necessary  for a  decision  and the  form of the  requests;  however,  the
Arbitrator's  decision with respect to the information and document  requests is
final.  The  Arbitrator  shall  give  liberal   consideration  to  the  Parties'
suggestions  and shall  thereafter  submit  proposed  information  and  document
requests  to the  Parties  and allow them  fifteen  (15) days after the  mailing
thereof  to  comment  on  such  proposals.  The  Arbitrator  shall  prescribe  a
reasonable  time  within  which  to  respond  to the  information  and  document
requests,  may grant those  extensions  of time he deems  appropriate,  and may,
after the responses have been served, submit additional information and document
requests until satisfied there is sufficient  information to make an allocation.
Responses to information and document requests must be signed and sworn to by an
authorized  representative  of each respective  Party. The Parties may object to
information  and  document  requests on the grounds set forth in Fed. R. Civ. P.
26(b)(1) and (c) within fifteen (15) days of the mailing of such information and
document requests,  and the Arbitrator shall establish a reasonable procedure to
rule  promptly  on such  objections.  Following  the  information  and  document
exchange,  the  Parties  will  have  ninety  (90) days in which to  conduct  and
complete depositions under a reasonable procedure established by the Arbitrator.
The Parties may object to depositions or deposition questions on the grounds set
out in Fed. R. Civ. P. 26(b)(1) and (c), and the  Arbitrator  shall  establish a
procedure  to rule  promptly  on such  objections.  The  Arbitrator  shall  have
available for  enforcement of rulings  relating to the  information and document
exchange and  depositions  the sanctions set forth in Fed. R. Civ. P.  37(b)(2),
except  contempt,  as well as the right to adjust a Party's award,  if any, as a
sanction.

7.   Hearing Procedure.  The following procedure shall govern the Arbitration
hearing.

     A.   After presentation of evidence, each Party shall have thirty (30) days
          for submission of Proposed Findings of Fact and Briefs. Within fifteen
          (15) days of the last day for such  submissions,  any Party may file a
          Reply to the Brief of any other Party or Parties.

     B.   Within  sixty  (60) days of the last day for  submission  of  Proposed
          Findings of Fact and Briefs,  the Arbitrator shall issue a Preliminary
          Order.  The  Preliminary  Order  shall  provide  a  specific  reasoned
          justification   for  the   Preliminary   Order   consistent  with  the
          requirements of Section 3 above.

     C.   Each Party will have thirty (30) days from the date of the Preliminary
          Order to file written exceptions to the Order.

     D.   Within  thirty (30) days of the  deadline for filing  exceptions,  the
          Arbitrator shall issue a Final Order, and provide a specific  reasoned
          justification  for the Final Order consistent with the requirements of
          Section 3 above.

     E.   The failure of the  Arbitrator  to meet the deadlines  established  in
          subparagraphs  B and D of this Section will not affect the validity or
          enforceability of the Final Order.

8.       Settlement Offers and Judgment on Final Award.

     At least ten (10) calendar days before the  commencement of the arbitration
hearings,  each side shall  provide a written  offer of  settlement to the other
side.  Each side  shall  concurrently  provide to the  Arbitrator  the same such
written offer of settlement at the time of the  commencement of the first day of
arbitration hearings.  The Arbitrator shall review each of the offers in camera.
The Arbitrator shall make the award in the amount of one settlement offer or the
other  settlement  offer.  The  Arbitrator  may not decide upon a dollar  figure
different than the dollar figure appearing in one or the other of the settlement
offers submitted by the Parties.

     The  Arbitrator  may  select  such  non-economic  procedures  to be used in
connection  with the unwinding  based upon the proposals of the Parties,  as the
Arbitrator may decide in his/her sole discretion.

9.       Enforcement.

     The award  rendered by the Arbitrator  shall be final,  and judgment may be
entered  upon  it  in  accordance  with  applicable  law  in  any  court  having
jurisdiction of the Party against whom the award was rendered.

II.      Product or Service Description

         A. Description.  All PCS Equipment will have the design  specifications
and features  determined by Sprint Spectrum in its sole commercially  reasonable
discretion. All PCS Equipment subject to this Addendum is and will be separately
identified  by model  number  and  other  description,  the  wholesale  price to
RadioShack,  and the  S.S.S.R.P.  set forth on Schedule  II.B to this  Addendum,
which may be amended,  including the removal or addition of specified  Products,
from time to time, by Sprint Spectrum.

         B. Price.  Sprint  Spectrum will sell to RadioShack the Products at the
wholesale  price set forth on  Schedule  II.B,  as amended  from time to time by
Sprint Spectrum,  which wholesale price will be no more than sixty-five  percent
(65%) of the S.S.S.R.P.  set forth on Schedule II.B., or otherwise  published in
writing by Sprint Spectrum to RadioShack.  If Sprint Spectrum designates, in its
sole  discretion one or more different  S.S.S.R.P.s for a model of PCS Equipment
for  different  Licensed  Markets,  the wholesale  price to  RadioShack  will be
sixty-five percent (65%) of the Weighted Average S.S.S.R.P. for that model. Upon
ten (10) business days notice by RadioShack  Sprint Spectrum agrees to calculate
and publish a Weighted Average S.S.S.R.P.  if such price exists. Sprint Spectrum
retains the right in its sole discretion to increase or decrease the S.S.S.R.P.,
nationally or for an individual  Licensed Market,  and may take into account all
factors,  including, but not limited to supply, demand, and any other prevailing
competitive forces. RadioShack may sell such Products at any legal price.

         All invoices for Products  supplied to RadioShack will allow RadioShack
a discount  of two  percent  (2%) of the  aggregate  purchase  price due for the
Products if paid  within ten (10) days of receipt of the invoice by  RadioShack,
with full payment  (without any  discount)  due within thirty (30) days from the
date of RadioShack's receipt of the invoice covering those products.

III.     Geographic Coverage (Rollout)

     A.   Licensed Markets. Sprint Spectrum has identified on Schedule III.1 and
          Exhibit III.2 to this Addendum  each  Licensed  Market,  as amended by
          Sprint Spectrum from time to time. Sprint Spectrum will amend Schedule
          III.1 within  ninety (90) days from the date of this Addendum with the
          estimated  dates  that  Sprint  Spectrum  will  have PCS  Commercially
          Operational  in each Licensed  Market,  and will update these dates on
          Schedule  III.1 from time to time as and when the estimated  dates are
          adjusted  and  will   immediately   notify   RadioShack  of  any  date
          adjustments  to  Schedule  III.1 by  telecopy  notice to  RadioShack's
          Director of Cellular Marketing.  The dates set forth on Schedule III.1
          are  good  faith  estimates  only and  Sprint  Spectrum  will  have no
          obligation to provide PCS in any Market on or before such dates.

     B.   Unlicensed  Markets.  Sprint Spectrum desires to, and will continue to
          strive to, obtain access to and PCS coverage of all Unlicensed Markets
          and Uncovered Markets through acquisitions,  buildout, joint ventures,
          affiliations,  resale agreements or other contractual relationships of
          or  with  third  party  entities,  necessary  to  provide  PCS in such
          Unlicensed Markets or Uncovered Markets.

     C.   Uncovered Markets. [________________________.]

     D.   Additional  Providers.  Subject  to  RadioShack's  reasonable  consent
          (except  as  provided  below),  Sprint  Spectrum  may  add one or more
          Additional  Providers  who  have a  license  or  contractual  right to
          provide PCS in one or more  Markets as a party to this  Addendum,  but
          only if such  Additional  Provider  agrees  to  execute a copy of this
          Addendum  and be  bound  and  subject  to  the  terms  and  conditions
          hereunder.  RadioShack's consent will not be unreasonably withheld and
          cannot be withheld for compensation reasons.  Notwithstanding,  Sprint
          Spectrum may add any  Additional  Provider to this  Addendum who is an
          Affiliate  of Sprint  Spectrum,  or who is an  Affiliate of any equity
          owner of  Sprint  Spectrum,  without  RadioShack's  consent.  Further,
          notwithstanding the first sentence of this paragraph,  Sprint Spectrum
          may add any other Additional Provider, without RadioShack's consent if
          Sprint  Spectrum  guarantees  the  payments  and  performance  of such
          Additional Provider's obligations to RadioShack under this Addendum.

         Subject to  RadioShack's  contractual  obligations  with third parties,
RadioShack agrees to solicit orders for the PCS Services of each such Additional
Provider in that  provider's  Market(s),  and be compensated for such service as
set forth in this Addendum. Notwithstanding anything to the contrary herein, the
Additional  Provider will have no liability for the direct obligations of Sprint
Spectrum  or any other  Additional  Provider  in the  Master  Agreement  or this
Addendum,  and Sprint Spectrum will have no liability for the direct obligations
of any Additional Provider hereunder, except as provided above. Upon addition as
a party, the Additional Provider's Market and Roll-Out Date(s) will be listed on
Schedule III.1 hereto.

         All references  herein to "Sprint  Spectrum"  shall mean the applicable
Additional  Provider  with  respect  to  Activations  and  PCS  Services  on the
Additional Provider's PCS network(s),  which such PCS Service shall in all cases
be marketed and sold by RadioShack as Sprint Spectrum Service.

IV.      Compensation/Terms of Payment

         A.       Compensation.

     1.   Activation Fee. Except as provided below,  Sprint Spectrum will pay to
          RadioShack an "Activation  Fee" of  [_________________]  multiplied by
          the number of Net Activations obtained by RadioShack.  Sprint Spectrum
          will not pay  RadioShack the Activation Fee in cases where PCS Service
          is  established  with respect to an item of PCS Equipment  stolen from
          RadioShack.  Sprint Spectrum will not pay RadioShack an Activation Fee
          in cases  where PCS  Service is  established  in  violation  of either
          subscriber   enrollment   procedures  or  fraud  prevention   policies
          developed by Sprint Spectrum and reasonably  agreed upon by RadioShack
          in writing and attached to this Addendum as an exhibit or exhibits.

     2.   Service Residual  Commissions.  During the Commission  Period,  Sprint
          Spectrum   will  pay  to   RadioShack   a   residual   commission   of
          [________________]  of the Net  Collected PCS Fees  attributable  to a
          RadioShack  PCS Customer  during the term of this  Agreement (the "PCS
          Residual Commissions").

          Upon  a  unilateral  termination  of  the  Master  Agreement  or  this
          Addendum,  and in lieu of the first  paragraph of Section 19(h) of the
          Master  Agreement  (subject  further to Section 20(b)(i) of the Master
          Agreement),  Sprint Spectrum has the option in Sprint  Spectrum's sole
          discretion,  but not the obligation, to pay to RadioShack, in one lump
          sum, within 60 days after the termination date, an amount equal to the
          present  value  as of the  effective  date  of  termination  (using  a
          discount  factor  equal to the then  current two year  Federal  T-Bill
          interest rate per annum) of a stream of Assumed  Payments,  as defined
          below) for 24 months,  less payments  made to  RadioShack  between the
          date of  termination  and the date of payment of the lump sum  payment
          under this  Subsection  2 in full  satisfaction  of Sprint  Spectrum's
          obligations  to  pay  PCS  Residual  Commissions  hereunder.  For  the
          purposes of this  option,  the lump sum  payment  will be equal to the
          Assumed Payment  multiplied by 24, and then discounted at the rate set
          forth above.  For the purposes of this  Agreement,  "Assumed  Payment"
          means the amount equal to 1/12th of the Service  Residual  Commissions
          actually  earned by RadioShack  from all Spectrum  Services on which a
          Service Residual Commission was earned by RadioShack during the twelve
          (12) month period  immediately  preceding a termination  of the Master
          Agreement. Any bounties,  Activation Fees, incentive program payments,
          market development funds,  advertising funds or any other non-residual
          or one time payments made by Sprint Spectrum to RadioShack will not be
          included in this calculation.

     3.   Product Price Protection. If Sprint Spectrum's wholesale price, as set
          forth on Schedule  II.B, to RadioShack  for any Product shall decline,
          RadioShack  shall receive a credit in an amount equal to the amount of
          the price decrease multiplied by the sum of the applicable quantity of
          such PCS Equipment (i) in transit by Sprint Spectrum's  carrier to any
          one of RadioShack's  warehouse distribution centers and (ii) inventory
          landed  in the  distribution  centers  during  the  thirty  (30)  days
          immediately preceding the effective date of such price decrease, which
          credit  Sprint  Spectrum  agrees may be offset by  RadioShack  against
          other amounts owed by RadioShack to Sprint Spectrum.

     4.   Product Stock Balancing.  Product stock balancing will be addressed on
          a case-by-case  basis on terms negotiated in good faith by the parties
          and based upon prevailing market conditions at the time.

          B.   Incentive Programs. Sprint Spectrum may, from time to time, offer
               RadioShack and/or  RadioShack  employees  incentive  compensation
               programs   to  promote  the  sale  of  PCS   Equipment   and  the
               solicitation  of  orders  for the  Service.  All  such  incentive
               compensation  programs will be  coordinated  through the Cellular
               Marketing  Department  of  RadioShack.  To the extent of any cash

               after payment of all prior market development binding commitments
               and  obligations  made  by the  RadioShack  and  Sprint  Spectrum

               first against  Activation Fee payments (other than Activation Fee

VIII.    RadioShack's Operational Duties and Responsibilities

         RadioShack  will perform the following  duties,  responsibilities,  and
obligations  with  respect  to the  Products  and PCS  during  the  term of this
Addendum:

          A.   Licensed  Markets.   RadioShack  will  distribute   Products  and
               Services  designated  by the JSC in  each  Licensed  Market  once
               Sprint Spectrum has PCS Commercially Operational in that Licensed
               Market.  The Products will be distributed  and orders for Service
               solicited  through those Retail Stores in that Market  designated
               by the Joint Steering Committee,  subject to the terms of written
               legally binding  contracts with third party vendors in the Market
               executed  by  RadioShack  before  Sprint  Spectrum's  Operational
               Notice as provided in Section III.C. above.

          B.   Customers. RadioShack will use commercially reasonable efforts to
               solicit  customer  orders for the Services within each applicable
               Market and promote the sale of the Products and  solicitation  of
               orders  for  Services  to  the  extent  reasonable,  lawful,  and
               consistent with RadioShack's written contractual obligations with
               providers  of  cellular  products  and  Cellular   Radiotelephone
               Services, where applicable, all subject to and in accordance with
               the terms and conditions hereof.

          C.   Minimum  Activation  Level/Sales  Quotas.  In  exchange  for  the
               payment of the Activation Fee  attributable to Net Activations in
               a Licensed Market for a given calendar month,  RadioShack  agrees
               to use all commercially  reasonable efforts to attain average Net
               Activations  greater  than or  equal  to the  Minimum  Activation
               Levels  established  for that  Licensed  Market for that calendar
               month. Sprint Spectrum may withhold payment of the Activation Fee
               attributable to a Licensed Market if RadioShack  fails to satisfy
               the Minimum Activation Levels for that Licensed Market during any
               three (3)  consecutive  month period.  Sprint  Spectrum will make
               payment of any withheld  Activation  Fees and  reinstate  current
               payment of the Activation Fee for that Licensed  Market as of the
               first day of the first month after which RadioShack satisfies the
               Minimum  Activation  Levels  for at  least  two  (2)  consecutive
               months.  Any  Activation  Fees withheld  pursuant to this Section
               VIII.C.  as of the  termination  of this  Addendum,  that are not
               payable to RadioShack as provided in this Section  VIII.C.,  will
               be retained by Sprint Spectrum.

               For the purposes of this Addendum,  "Minimum  Activation  Levels"
               for a Licensed Market will be: [ ]

               The  Minimum  Activation  Levels in any  Licensed  Market will be
               waived  for  the   purposes  of   achieving   Activation   Period
               requirements  in any  month  where  there  is a  shortage  of PCS
               Equipment or Service  supplied by Sprint  Spectrum or  Additional
               Providers  that would  restrict or limit the sales of PCS through
               the Retail Stores in that Market.  A shortage of PCS Equipment is
               defined as an average  per Retail  Store  availability  quantity,
               evenly  distributed  throughout  the month,  of less than one and
               one-half times the previous month's sales per Retail Store.

         Notwithstanding  the first paragraph of this Section C, RadioShack will
no longer be required to satisfy the Minimum Activation Levels in a Market after
the Third Activation Period for that Market.

          D.   Establishment  of PCS  Service.  Schedule  VIII.D  sets forth the
               process by which  RadioShack  PCS  Customers  will  activate  and
               establish a PCS customer account with Sprint Spectrum.

          E.   Equipment Purchases.  RadioShack may purchase Product from Sprint
               Spectrum's   inventory,   subject   to   availability,   and  for
               RadioShack's own account, solely for the purpose of resale to end
               users within the Licensed Markets; provided, however, that except
               where prohibited by law, the resale of any Product to an end user
               must be for the purpose of using Sprint Spectrum's  Service by an
               end user within the Licensed  Markets.  RadioShack may, from time
               to time, purchase PCS Equipment from another source, provided the
               PCS   equipment    satisfies    Sprint    Spectrum's    technical
               specifications.  With the  approval of the JSC,  Sprint  Spectrum
               will,  upon  execution  of  the  Master  Agreement,  provide  the
               technical specifications for PCS Equipment to RadioShack, subject
               to  applicable  supplier  contracts.  In  no  event  will  Sprint
               Spectrum have any liability  with respect to the wholesale  price
               paid by  RadioShack  with  respect  to the sale of PCS  equipment
               provided by anyone other than Sprint Spectrum. Without limitation
               of the foregoing,  and excluding  sales and shipments of Products
               to Retail Stores,  RadioShack will not transship,  sell, transfer
               or  otherwise  distribute  outside  the  Licensed  Markets  where
               RadioShack   solicits   orders  for  the  Services  any  Products
               purchased  from  Sprint  Spectrum.  All  purchase  orders will be
               subject  to  and  incorporate  the  terms  of the  P.O.  Addendum
               attached to the Master Agreement.

          F.   Intentionally left blank.

          G.   Diligence.  RadioShack  will at all times exert all  commercially
               reasonable  efforts to promote and enhance the objectives of this
               Addendum. In connection therewith,  and except as may be provided
               otherwise in advertising  guidelines  established under Section 5
               of the Master Agreement,  RadioShack will not define, describe or
               market Cellular Radiotelephone Service as PCS, or PCS as Cellular
               Radiotelephone   Service,  in  its  advertising  and  promotional
               efforts  in  Licensed   Markets  and  will  take  those   actions
               commercially  reasonable  to ensure  RadioShack's  employees  and
               associates comply with this covenant.  If, however,  RadioShack's
               abilities to compete and to maximize  sales of Product and orders
               for  Services  (for  example,   where  the  accepted  or  general
               marketing  and  promotion   methods  of  other  PCS  or  cellular
               providers  with whom  RadioShack  must  compete  equate  cellular
               service with PCS or vice-versa,  or where the consumer perception
               in the  marketplace  so  equates  the  two) are  limited  by this
               provision,  RadioShack  may  use all  lawful  means  to meet  the
               competition  and  to  market  the  PCS  Product  and  Service  to
               consumers.

               responsible for securing and maintaining the necessary regulatory
               approvals to operate a PCS system.

          B.   Approvals.  This  Addendum is subject to any  necessary  approval

               said requirements  which will be placed by RadioShack with Sprint
               Spectrum  which will be subject to acceptance by Sprint  Spectrum
               in  accordance  with the P.O.  Addendum  attached  to the  Master

               Products  RadioShack  cannot  use with any other  PCS  provider's
               system or  handsets.  Upon  notice  thereof  and tender by Sprint
               Spectrum of such  purchase  price,  RadioShack  will deliver such
               Products  and all right,  title and  interest  therein,  free and

               Sprint  Spectrum will prepay all costs  associated  with shipping
               such Products back to Sprint Spectrum. Sprint Spectrum,  however,
               will not be required to  repurchase  and will be entitled to, and
               will receive from RadioShack a credit to the extent that any such
               repurchased  Products  are  not  in  acceptable   condition,   as
               reasonably determined by Sprint Spectrum.

XII.     Nonrecourse

         Unless  a  Party  to  this  Addendum,   no  past,   present  or  future
shareholder,  limited or general  partner in or of RadioShack or Sprint Spectrum
or any  Additional  Provider,  no  parent  or  other  Affiliate  of any  company
comprising  RadioShack,  and  no  parent  or  other  affiliate  of  any  company
comprising  Sprint  Spectrum  or an  Additional  Provider,  and no  shareholder,
officer,   employee,   servant,   executive,   director,   agent  or  authorized
representative of any of them (each, an "Operative") will be liable by virtue of
the direct or indirect  ownership  interest of such  Operative in such Party for
payments due under this Addendum or for the  performance of any  obligation,  or
breach of any representation or warranty made by such Party hereunder.  The sole
recourse  of  RadioShack  or  Sprint  Spectrum  or an  Additional  Provider  for
satisfaction of the obligations of Sprint Spectrum or an Additional  Provider or
RadioShack under this Agreement will be against the Party and the Party's assets
and not against any  Operative or any assets or property of any such  Operative.
In the event  that a default  occurs in  connection  with such  obligations,  no
action  will be brought  against any such  Operative  by virtue of its direct or
indirect  ownership  interest in RadioShack or Sprint  Spectrum or an Additional
Provider, as the case may be.

         This  Addendum  may be executed in any number of  counterparts,  all of
which when taken together  shall  constitute  one and the same  instrument.  Any
