                           SCOPE OF AGREEMENT; ORDERS

         2.1      Customer hereby agrees to purchase from Nortel Networks, and
Nortel Networks hereby agrees to furnish, deliver, Install, sell and/or license
(on a right-to-use

                                       9

<PAGE>

basis) to Customer in accordance with the time schedules set forth in the
applicable Purchase Orders (which Purchase Orders have been accepted by Nortel
Networks pursuant to Section 2.9), the Equipment, Software and Services
comprising the Initial Order described in Attachments A and B. The Purchase
Orders for the Initial Order issued by Customer and accepted by Nortel Networks
prior to the date of this Agreement shall be subject to all of the terms and
conditions of this Agreement to the same extent as if such Purchase Orders had
been issued after the date hereof. In addition to the Initial Order, Customer
has the right to purchase from Nortel Networks hereunder, and Nortel Networks
agrees to furnish, deliver, Install, sell and/or license (on a right-to-use
basis) to Customer, such additional Expansions, Equipment, Software and Services
as, when and if ordered by Customer during the Term of this Agreement, and the
terms and conditions of this Agreement shall apply to such purchases.

         2.2      If Customer is enrolled in any Nortel Networks electronic
commerce program, Customer agrees to comply with the terms of such program.
Customer and Nortel Networks agree that all electronic Purchase Orders issued
are equivalent to a written Purchase Order, are governed by the terms and
conditions of this Agreement and that in the event of any conflict between this
Agreement and the information contained in Customer's or Nortel Networks'
electronic commerce website, this Agreement governs. Customer shall be
responsible for the use and protection of all electronic commerce passcodes
provided by Nortel Networks and agrees that all Purchase Orders submitted using
such passcodes are valid and binding Purchase Orders authorized by Customer.
Nortel Networks shall have no liability to Customer due to Customer's failure to
access

                                       10

<PAGE>

Customer's or Nortel Networks' electronic commerce website or errors or failures
relating to its operation.

         2.3      Except pursuant to Nortel Networks' repair and replacement
services or as may be mutually agreed to in writing by the parties, all
Equipment and Software provided to Customer hereunder shall be new, and Nortel
Networks shall not sell or deliver to Customer any used or refurbished
Equipment. Customer represents and warrants that it is buying Equipment,
Software and/or Services for its own internal use and not for resale. However,
Customer may resell Equipment after internal use.

         2.4      Nortel Networks hereby agrees to provide, as, when and if
ordered by Customer, the Service and Support Plan and other services set forth
in Attachment C.

         2.5      This Agreement shall constitute a binding agreement on the
part of Customer to purchase from Nortel Networks the Initial Order described in
Attachments A and B (as such Attachments may be modified from time to time by
Change Orders in accordance with the terms of this Agreement); provided,
however, that the parties acknowledge and agree that the aggregate amount of
base stations and cell sites purchased by Customer pursuant to Purchase Orders
for the Initial Order issued by it to Nortel Networks may vary upwards or
downwards by up to twenty (20%) percent from the amounts set forth in
Attachments A and B. Purchase Orders submitted to Nortel Networks for the
Initial Order and any Expansions shall reference this Agreement and include the
quantity, price, Nortel Networks' quotation number (if any) and billing
instructions, installation location(s), requested delivery dates, requested
commencement dates for Services, the Statement of Work (if any) and any other
special instructions. Where Customer desires the assistance of Nortel Networks
in determining which

                                       11

<PAGE>

Equipment, Software and/or Services are required for an Expansion to a System,
Customer shall submit to Nortel Networks the information necessary for the
furnishing by Nortel Networks of a proposal. Nortel Networks shall, within
fifteen (15) Business Days thereafter, submit to Customer a proposal including
pricing, lead times and other information as may be requested by Customer. If
such proposal is acceptable to Customer, Customer shall submit to Nortel
Networks a Purchase Order therefor, and Customer and Nortel Networks shall be
responsible for the successful completion of their respective items in
accordance with such proposal. Any such proposal shall contain provisions
relating to the respective responsibilities of Customer and Nortel Networks as
the parties shall mutually agree in writing. If Customer rejects a proposal for
Services submitted by Nortel Networks under this Section 2.5, Customer may elect
to perform such Services itself or to have such Services performed on its behalf
by a subcontractor of Customer and, subject to Section 11.3, the warranties set
forth in this Agreement shall not be affected.

         2.6      Unless otherwise mutually agreed to in writing, the prices and
delivery lead times for Equipment, Software and Services ordered pursuant to
Purchase Orders shall be in accordance in all respects with the terms and
conditions of this Agreement (including all Attachments hereto which contain all
discounts, incentives and delivery lead times being offered by Nortel Networks
to Customer).

         2.7      The parties may mutually agree upon Statements of Work in
conjunction with Purchase Orders delivered by Customer and accepted by Nortel
Networks in accordance with this Article 2. Each of Nortel Networks and Customer
shall perform their respective responsibilities as set forth in any such
Statements of Work. If any

                                       12

<PAGE>

Statement of Work fails to set forth any responsibility which is required for a
System or any Equipment or Software to operate in accordance with the
Specifications, the parties undertake to promptly discuss and agree as to which
party shall be responsible for the performance of such responsibilities and the
price, if any, to be paid to Nortel Networks and the time schedules of such
performance. There are no design, engineering, Installation, management or other
fees payable to Nortel Networks for any services to be rendered by Nortel
Networks pursuant to any Statement of Work or this Agreement except for the fees
which are expressly provided for in this Agreement, the applicable Purchase
Order (and Statement of Work, if any) or any applicable Change Orders.

         2.8      Delivery locations may be changed by Customer up to thirty
(30) days prior to shipment without additional payment or penalty, unless
otherwise mutually agreed.

         2.9      Nortel Networks agrees to confirm receipt of each such
Purchase Order and all Purchase Orders for forecasted Equipment, Software and
Services, as provided in Article 13, that are within Nortel Networks' standard
delivery lead times as set forth in Attachment F, shall automatically be
accepted unless the terms of the Purchase Order do not conform in all material
respects to this Agreement or if the Purchase Order is incomplete in a material
respect; provided, however, that Nortel Networks shall promptly notify Customer
in writing of any non-conforming or incomplete Purchase Order within five (5)
Business Days of receipt thereof. All Purchase Orders shall be sent to Nortel
Networks at the address identified by Nortel Networks. Should Nortel Networks
receive a Purchase Order with lead times that are shorter than Nortel Networks'
standard lead times (and, prior to or contemporaneously with the issuance of
such Purchase Order,

                                       13

<PAGE>

verbal notification from Customer that such Purchase Order contains such shorter
lead times), Nortel Networks shall promptly indicate in writing (either by
e-mail or fax) to Customer whether such shortened lead times are acceptable. If
Nortel Networks shall deem a shortened lead time unacceptable, the parties
hereto shall endeavor in good faith to agree upon lead times that are mutually
acceptable, but in no case shall such lead times be longer than the standard
lead times existing on the date such Purchase Order was initially received by
Nortel Networks. The agreed upon (or standard) lead times shall be calculated as
commencing upon the date on which Nortel Networks confirms receipt of the
applicable Purchase Order. Should Nortel Networks not notify Customer of its
non-acceptance of a shortened lead time within ten (10) days of its receipt of
the Purchase Order containing the shortened lead time (and so long as Customer
provided Nortel Networks with the proper verbal notification specified in this
Section 2.9), such Purchase Order shall be deemed accepted without amendment and
without any further confirmatory action by either party.

         2.10     This Agreement shall be effective as of the Effective Date and
shall terminate on the third anniversary of the Effective Date or on such
earlier date on which this Agreement may be terminated in accordance with its
terms, except as to those provisions which by their express terms survive such
termination. Nortel Networks and Customer shall be bound to fulfill any
obligations in respect of Purchase Orders delivered and accepted hereunder in
accordance with the terms of this Agreement to the extent such obligations have
not been so fulfilled on the termination date of this Agreement. The period from
the Effective Date of this Agreement to the third anniversary thereof or such

                                       14

<PAGE>

earlier date of termination pursuant to the terms hereof shall be hereinafter
referred to as the "Term."

         2.11     With respect to GSM equipment and software purchased for each
of the GSM roamer markets specifically set forth on Attachment H hereto (and not
with respect to any other markets or technology), Customer shall, during the
Term, make Nortel Networks its exclusive supplier for GSM equipment and
software; provided, however, that notwithstanding such exclusivity arrangement,
Customer may purchase from entities other than Nortel Networks any product
(whether equipment or software) having a material functionality or feature which
is not available from Nortel Networks, unless Nortel Networks can provide such
functionality or feature at a comparable price through another reasonable
solution. The exclusivity set forth in this Section 2.11 shall terminate in the
event that Nortel Networks is in breach under any material term of this
Agreement and such breach has not been cured within the time periods set forth
in Section 22.

         2.12     With respect to the types of CDMA equipment and software
purchased as part of the Initial Order (and not with respect to any other types
of CDMA equipment and software, including EVDO equipment and software), Customer
shall, during the Term, make Nortel Networks its exclusive supplier for such
equipment and software purchased for each of the new CDMA markets specifically
set forth on Attachment B; provided, however, that notwithstanding such
exclusivity arrangement, Customer may purchase from entities other than Nortel
Networks any product (whether equipment or software) having a material
functionality or feature which is not available from Nortel Networks, unless
Nortel Networks can provide such functionality or feature at a comparable price
through another reasonable solution. The exclusivity set forth in this Section
2.12 shall

                                       15

<PAGE>

terminate in the event that Nortel Networks is in breach under any material term
of this Agreement and such breach has not been cured within the time periods set
forth in Section 22.

         2.13     Customer shall issue Purchase Orders for, and take delivery
of, an aggregate amount of Equipment, Software and Services during the Term
equal to or greater than the Volume Commitment. In the event that at the end of
the Term Customer has failed to issue such Purchase Orders for, and take
delivery of, an aggregate amount of Equipment, Software and Services equal to or
greater than the Volume Commitment, then Customer shall pay liquidated damages
to Nortel Networks in the amount of [CONFIDENTIAL MATERIAL OMITTED AND FILED
SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
CONFIDENTIAL TREATMENT] of the portion of the Volume Commitment that remains
unfulfilled at the end of the Term; provided, however, that in no event shall
the amount paid by Customer pursuant to this Section 2.13 exceed [CONFIDENTIAL
MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT]. Such amount shall
be due and payable within thirty (30) days following the date of Nortel
Networks' invoice therefor, which invoice shall be accompanied by a detailed
list of the Purchase Orders accepted hereunder during the Term and the aggregate
net purchase price associated with each such Purchase Order.

         5.1      Subject to (a) any modifications thereto permitted pursuant to
this Article 5, (b) any delays caused solely by Customer by reason of its breach

prepaying the cost of transportation and insurance pursuant to its delivery
obligations under this Agreement, and Customer shall pay to Nortel Networks the

Except as provided in Section 5.7, Nortel Networks shall convey good and clear
title to the Equipment, free and clear of all liens, suits, charges, claims,
liabilities, restrictions and encumbrances of any nature or kind whatsoever,
other than any lien or encumbrance which arises solely out of the actions of
Customer, its employees, agents or subcontractors. Nothing in this Article 5
shall, during the period a party has the risk of loss with respect to an item,
relieve the other party of responsibility for loss or damage to such item which
results from the acts or omissions of such other party or such other party's
employees or agents.

         5.6      Nortel Networks hereby represents and warrants to Customer
that it has all necessary approvals, authorizations and licenses required for it
to perform all of its duties and obligations hereunder.

Nortel Networks with respect to an item of Equipment or Software sold to
Customer hereunder, Customer grants to Nortel Networks a continuing purchase
money security interest in such item of Equipment sold and/or Software licensed
under this Agreement. Customer shall reasonably cooperate with Nortel Networks
in preserving and protecting such purchase money security interest. Customer
authorizes Nortel Networks to file financing

                                       23

of Equipment and Software without the signature of Customer where permitted by
law.

                             TESTING AND ACCEPTANCE

         6.1      Nortel Networks shall Install (where contracted to do so) all
Equipment and Software to be ready for Acceptance Tests no later than the
scheduled In-Service Date in accordance with the applicable Purchase Order. Upon
completion of Installation of the Equipment and Software or portions thereof,
Nortel Networks shall test the Equipment and Software in accordance with the
Acceptance Test Plan ("Acceptance Tests") attached as part of the applicable
Statement of Work.

         6.2      Acceptance Tests will be conducted on the Equipment and
Software to demonstrate that each item of Equipment and Software comprising a
part of the System, as Installed, will operate in accordance with the
Specifications.

         6.3      Nortel Networks shall notify Customer at least five (5) days
before the date on which the Acceptance Tests shall be conducted. If Customer or
its representative does not attend the Acceptance Tests, Nortel Networks shall
proceed with the tests and immediately forward the test results (including
actual test sequences, deviations, and retests necessary to obtain successful
conclusion) to Customer. If Customer or its representative (which representative
shall be bound by all confidentiality requirements applicable to Customer)
attends the Acceptance Tests, Nortel Networks and Customer or its representative
shall jointly conduct the Acceptance Tests and shall each sign the form provided
as part of the test procedure. If the Equipment or Software does not fulfill all
of the requirements of the applicable Acceptance Tests and such failure is a
result of any breach of any provision or obligation of Nortel Networks under
this Agreement or is

                                       24

<PAGE>

caused by any item of Equipment or Software, or any Service, provided by Nortel
Networks, Nortel Networks shall, at its sole expense, correct the defects as
soon as practicable. The Acceptance Tests (or so much of them as necessary)
shall be recommenced immediately after such correction in accordance with this
Section 6.3. Upon successful completion of the applicable Acceptance Tests,
Nortel Networks shall submit to Customer written notice thereof along with
Acceptance forms certifying all of the test results and stating that all of the
applicable Equipment and/or Software has been Accepted in accordance with all of
the requirements of this Agreement and that the same performs in accordance with
the Specifications. Customer shall sign or reject such Acceptance forms within
five (5) Business Days of receipt thereof to signify that the Equipment and/or
Software is Accepted or is not Accepted. In the absence of a notice of rejection
given in good faith within such five (5) Business Day period, such Equipment
and/or Software shall be deemed Accepted. Any notice of rejection shall be given
in writing to Nortel Networks' project manager. If there is a dispute as to
whether the Equipment and/or Software has passed the applicable Acceptance
Tests, the parties shall use reasonable best efforts (which shall include
escalation of such dispute to a senior management level) to resolve the dispute
as soon as practicable or it shall be submitted to the Third Party Engineer
pursuant to Article 38.

         6.4      Customer shall not unreasonably withhold Acceptance. Minor
deficiencies recorded in the test results or minor shortages which would not
affect service to subscribers, data collection regarding billing,
administration, maintenance or the commercial operation of the Equipment,
Software or the System or create a safety hazard for personnel shall not
postpone the issuance of Acceptance forms pursuant to this Article

6, but Nortel Networks shall remain obligated to perform in the manner described
in this Agreement.

                               DELAY AND PENALTIES

         7.1      If due to the fault or negligence (regardless of the severity
level of negligence) of Nortel Networks, (a) Acceptance (with respect to items
of Equipment and Software for which Nortel Networks is performing Installation)
or delivery (with respect to Furnish Only items of Equipment and Software for
which Nortel Networks is responsible for transportation) does not occur with
respect to any of the items comprising the September 30, 2003 portion of the
Initial Order (designated as the Phase I items in Attachment D) or the December
31, 2003 portion of the Initial Order (designated as the Phase II items in
Attachment D)(collectively, "Critical Items") on the scheduled date for
Acceptance or delivery (as applicable) thereof as set forth in Attachment D (as
such date may be amended by Change Orders pursuant to the terms of this
Agreement), then Customer shall be entitled to, and Nortel Networks shall pay to
Customer, liquidated damages in accordance with Section 7.2; provided, however
that such liquidated damages shall only accrue during such delay of Acceptance
or delivery, and shall not be payable to Customer unless, due to the fault or
negligence (regardless of the severity level of negligence) of Nortel Networks
the Critical Items have not been Accepted and placed In-Service on or before
September 30, 2003 or December 31, 2003, as applicable, at which time all of the
accrued but unpaid liquidated damages payable by Seller to Customer under this
Article 7 shall be immediately due and payable.

         7.2      (a)      The parties agree that damages for delay are
difficult to calculate accurately and therefore agree to fix, as liquidated
damages (and not as a penalty), an

                                       26

<PAGE>

amount equal to [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL
TREATMENT] per week of delay up to a cumulative maximum amount of [CONFIDENTIAL
MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT] of the aggregate
net purchase price (calculated in accordance with Attachment A or the applicable
Purchase Order, and including Installation costs, if applicable, but not
including the Executive Discount described in Attachment A) of those items of
Equipment and/or software which were delayed. In the event that the delay of
Acceptance or delivery (as applicable) of a Critical Item, prevents or
materially affects the operation of other items of Equipment or Software which
are part of the Initial Order, then Customer's right to receive liquidated
damages shall apply to such other Equipment and Software as well.

                  (b)      Liquidated damages will be provided to Customer as
credits towards the future purchase of GSM, TDMA and CDMA Equipment and Software
("Product Credits") which may be applied to up to twenty-five percent (25%) of
any future Purchase Orders for Equipment or Software until such Product Credits
have been used in full. Any such Product Credits must be utilized during the
Term.

                  (c)      Customer will inform Nortel Networks of the
imposition of the liquidated damages in writing. Within thirty (30) calendar
days following the date on which Nortel Networks is so informed, Nortel Networks
shall be obligated to issue to Customer Product Credits in the amount of such
liquidated damages except to the extent

                                       27

<PAGE>

they have been contested in good faith by Nortel Networks within such thirty
(30) day period.

         7.3      It is expressly agreed that the liquidated damages provided in
this Article 7 and their payment do not extinguish or relieve the performance of
any of the obligations Nortel Networks is required to perform hereunder, which
obligations shall continue in full force and effect until fully performed in
accordance with the terms hereof. Liquidated damages under this Article 7 shall
be Customer's exclusive remedy for delay by Nortel Networks in delivery or
Acceptance, as applicable, of the Critical Items.

         7.4      In the event that there are any delays in the performance by
Nortel Networks under this Agreement (whether or not such delays will result in
liquidated damages under this Article 7) then, upon notification by Customer of
such delays, Nortel Networks shall use commercially reasonable efforts to assign
additional personnel, reallocate resources, expedite deliveries and take such
other actions as may be required to eliminate such delay.

                                    TRAINING

                  Nortel Networks will provide training to Customer's personnel
within the Territory in the operation and maintenance of the Equipment as set
forth in Attachment E.

                                  DOCUMENTATION

         Nortel Networks will furnish Customer, at no additional cost to
Customer, one CD-ROM copy of all Documentation required by Customer for the
Equipment, Software and Services purchased hereunder. In addition, such
Documentation shall be available to Customer in web based format. Nortel
Networks represents that the Documentation, in

                                       28

conjunction with any applicable training, is all that is reasonably necessary
for Customer to use, maintain and operate the Equipment, Software and System
purchased by Customer pursuant to this Agreement.

                                  FORCE MAJEURE

         10.1     Unless preventable by the timely and proper performance of
their respective obligations under this Agreement, neither Nortel Networks nor
Customer will be liable for non-performance or defective or late performance of
any of their obligations hereunder to the extent and for such periods of time as
such non-performance, defective performance or late performance is attributable
to acts of God, war (declared or undeclared), unforeseeable acts (including
failure to act) of any governmental authority (de jure or de facto), riots,
revolutions, fire, floods, explosions, sabotage, nuclear incidents, earthquakes,
hurricanes, sinkholes, epidemics, strikes, delays of suppliers or subcontractors
for the same causes if no equivalent sources for such supplies or services are
readily available, or other similar causes beyond the reasonable control of a
party (collectively, "Force Majeure Events").

         10.2     In the event that either of the parties wishes to claim
excusable delay by reason of a Force Majeure Event, it shall state it in writing
to the other party within five (5) Business Days (or such longer period as may
be reasonable as a result of the Force Majeure Event) following the date on
which its occurrence was known, accompanied by reasonable evidence of the Force
Majeure Event and a statement of the impact such Force Majeure Event has had or
is expected to have upon such party and its ability to perform its obligations
hereunder.

         10.3     If the Force Majeure Event continues for more than thirty (30)
consecutive days, or it is proven that it will continue for more than such
thirty (30) day period, the parties shall upon written request of either party
meet to try to determine an appropriate action, remedy or solution to the
problems caused by such delay.

                 WARRANTIES, REMEDIES: LIMITATIONS: DISCLAIMERS

         11.1     (a)      Nortel Networks warrants that during the applicable
Warranty Period the Equipment, excluding Reseller Items, furnished under this
Agreement shall be free from defects in materials and workmanship, and shall
meet all of the functional and performance criteria (including the interworking
of all Nortel Networks supplied Equipment and Software) set out in and otherwise
conform to all of the applicable portions of the Specifications, and that all of
the Services furnished by Nortel Networks under this Agreement shall be
performed with due care and skill in a professional and workmanlike manner. Any
and all claims for breach of this warranty are conclusively deemed waived unless
made in writing (or orally with prompt confirmation in writing) during the
appropriate Warranty Period. Where Equipment or any part thereof is repaired or
replaced under the warranties contained herein, the repaired or replaced item
shall be warranted for the balance of the original Warranty Period or a period
of ninety (90) days from the date of repair or replacement whichever is longer.
Except as provided in the preceding sentence, performance of Nortel Networks'
warranty obligations shall not extend the Warranty Period.

                  (b)      If defects in materials or workmanship or
nonconformity with the performance Specifications appear within the Warranty
Period, Nortel Networks' sole obligation and Customer's exclusive remedy under
this warranty are limited to the

                                       30

<PAGE>

prompt replacement or repair, at Nortel Networks' option and own expense, of the
defective components of the Equipment, or the correction of the faulty Services
furnished by Nortel Networks hereunder. Such repair or replacement includes
materials, labor and services. In the event Nortel Networks is unable to correct
faulty Services, the sole remedy of Customer shall be to recover the applicable
portion of the compensation paid to Nortel Networks for such Services. Customer
shall bear the risk of loss and damage and all transportation costs for
defective Equipment shipped to Nortel Networks and Nortel Networks shall bear
the risk of loss and damage and all transportation costs for replacement
Equipment shipped to Customer. Good title to defective or replacement Equipment
shall pass to Nortel Networks or Customer, as appropriate, upon receipt thereof.

         11.2     Nortel Networks warrants that, provided the Software is not
altered by Customer, and provided the Software is used in conjunction with
Equipment purchased under this Agreement and such Equipment has been maintained
and utilized in accordance with Nortel Networks' recommended maintenance
procedures (as set forth in the Documentation) and the Software license set
forth in Attachment G hereof, the Software, excluding Reseller Items, shall
function during the Warranty Period in all material respects in accordance with
all of Nortel Networks' Specifications for the Software. In the event the
Software fails to so perform or conform, Customer's exclusive remedy under this
warranty shall be to require Nortel Networks to promptly correct such failure
and such remedy is conditioned upon Nortel Networks' receiving written notice
within the Warranty Period (or oral notice promptly confirmed in writing) of
such failure. The correction of any Software failures shall not extend the
Software Warranty Period.

         11.3     Nortel Networks' obligations under this Article 11 shall not
apply to (i) Equipment or components thereof such as fuses and bulbs that are
normally consumed in operation, or have a normal life inherently shorter than
the Warranty Period; (ii) defects that are solely attributable to improper
storage, installation, use, maintenance or repair by Customer (including
operation of the Equipment outside the environmental parameters defined in the
Specifications); (iii) improper operation of Equipment with hardware not
authorized by Nortel Networks (or reasonably contemplated by Nortel Networks) to
be used with such Equipment, or use of the Equipment with any improperly
operating hardware or equipment, if such defect is caused by such hardware or
such improperly operating hardware or equipment; (iv) Equipment or components
thereof that, due to no fault of Nortel Networks, have been subjected to any
other kind of misuse or detrimental exposure or have been involved in an
accident, fire, explosion, Act of God, or has otherwise been damaged for any
reason not attributable to Nortel Networks, or (v) any defects attributable
solely to the improper alteration, repair, installation or relocation by any
party other than Nortel Networks or Nortel Networks' agents. For purposes of
clause (v) above Equipment shall not be deemed to have been "installed" by
another party if all that has been done to such Equipment is the routine plug-in
of the components in accordance with the Northern Telecom Practices and
Procedures guidelines.

         11.4     (a)      (i)      If, during the Warranty Period set forth in
Section 11.1, Customer experiences failures of electronic circuit board
components, RBS subassemblies or other Equipment (which other Equipment may be
deinstalled and reinstalled by Customer in the ordinary course of business)
which the Chief Technical Officer of Customer (hereinafter the "Customer CTO")
reasonably believes to be

                                       32

excessive, (1) the Customer CTO shall bring such failures to the attention of
Nortel Networks by giving written notice to Nortel Networks under Section 35.1
hereof, (2) both Customer and Nortel Networks shall, without undue delay,
investigate the cause of such failures, and (3) where, within a reasonable
period not to exceed one (1) week, it cannot be clearly determined that the
cause of such failure is properly attributable to Customer, Nortel Networks
shall, without charge to Customer, supply to Customer additional spare boards,
subassemblies or such other Equipment of each type so depleted, as necessary to
maintain an adequate emergency replacement stock, until implementation of a
permanent remedy.

                           (ii)     Upon implementation of a permanent remedy,
all excess boards, subassemblies or other Equipment supplied by Nortel Networks
to Customer under Section 11.4(a)(i) shall be returned to Nortel Networks, and
all in-service and spare stock boards, subassemblies and other equipment which
are the subject of the corrections contemplated by this Section 11.4(a)(ii)
shall be either, at the option of Nortel Networks, promptly repaired or replaced
at no charge to Customer, in accordance with an agreed schedule.

                  (b)      If, during the Warranty Period set forth in Section
11.1, Customer experiences failures of Equipment (other than electronic circuit
board components, RBS subassemblies or other Equipment which may be deinstalled
and reinstalled by Customer in the ordinary course of business), which Customer
CTO reasonably believes to be excessive, Nortel Networks shall give priority to
the remedy of the cause of the failures (and in accordance with the response,
workaround and cure times set forth in Attachment C). During the period prior to
the implementation of a permanent remedy, Nortel

                                       33

Networks agrees to negotiate in good faith for adjustments in warranties and
freight payments commensurate with the effect upon Customer caused by such
failures and to make adjustments as are mutually agreed upon by Customer and
Nortel Networks.

         11.5     In no event shall Nortel Networks be required to provide
support for any version of Software that is (a) with respect to Software
supporting GSM, CDMA or TDMA technology, more than two (2) versions behind the
then current version of Software that Nortel Networks is generally offering to
its customers and (b) with respect to Software supporting any other technology,
more than one (1) version behind the then current version of Software that
Nortel Networks is generally offering to its customers.

         11.6     If any Equipment or Software is rendered inoperative as a
result of a natural or other disaster, Nortel Networks will make all reasonable
efforts to promptly supply or help locate backup or replacement Equipment or
Software for Customer, by using reasonable efforts to waive any delivery
schedule priorities and to make replacement Equipment or Software available from
the facility then producing such products, or from inventory.

         11.7     Nortel Networks response times, workaround times and cure
periods for all warranty related repairs for the System, Equipment and Software
are set forth in Attachment C hereto. Such times are based upon the severity
level of the applicable defect, as set forth therein.

         11.8     It is the intention of the parties that any defects in
materials or workmanship or nonconformity with the performance Specifications in
the System, Equipment or Software shall be corrected as promptly as practicable
regardless of fault, and in this regard, Nortel Networks agrees to use
commercially reasonable efforts to

                                       34

<PAGE>

work with and cooperate with Customer and any other manufacturer, vendor or
contractor to correct any such defect or nonconformity to the extent that Nortel
Networks has the capacity to do so. Nortel Networks shall, at Customer's
request, provide reasonable assistance to Customer in determining the cause of
such defect or nonconformity and recommend the appropriate action. Nortel
Networks shall, upon its receipt of a request for assistance hereunder from
Customer, use commercially reasonable efforts to correct any such defect or
nonconformity in a System, item of Equipment or Software or any other equipment
or software (whether or not such defect or nonconformity is the responsibility
of Nortel Networks) as promptly as practicable and bill Customer for such. If
Customer and Nortel Networks disagree as to the cause of the defect or
nonconformity or the action to be taken, then, at Customer's written request,
Nortel Networks shall nevertheless correct such defect or nonconformity (whether
or not such defect or nonconformity is the responsibility of Nortel Networks) as
promptly as practicable and generate a bill to Customer for such. The parties
shall thereafter negotiate in good faith to determine the party responsible for
such defect or nonconformity, and if they are unable to resolve such dispute,
such dispute shall be submitted to a Third Party Engineer in accordance with
Article 38. Nothing contained in this Section 11.8 shall require Nortel Networks
to repair or modify any equipment purchased by Customer from any third party
unless Nortel Networks has the ability to do so.

         11.9     Subject to Section 11.3, Customer may at any time acquire
equipment and software from a source other than Nortel Networks, and such
equipment and software

                                       35

<PAGE>

may be interconnected with the Equipment and Software without affecting the
warranties contained in this Article 11.

         11.10    With respect to Reseller Items, in lieu of the warranties set
forth herein Reseller Items shall have the warranties given to Nortel Networks
by the third parties supplying such Reseller Items to Nortel Networks and such
warranties shall inure, to the extent applicable or permitted, to the benefit of
Customer, and Customer shall have the right to enforce such warranties directly
with the third party providing the applicable Reseller Item to Nortel Networks
or, if Customer is not permitted to enforce such warranty directly through
Nortel Networks.

         11.11    THE WARRANTIES AND REMEDIES SET FORTH IN THIS ARTICLE 11
CONSTITUTE THE ONLY WARRANTIES (OTHER THAN THE WARRANTIES AS TO TITLE CONTAINED
IN SECTION 5.5) WITH RESPECT TO THE EQUIPMENT, SOFTWARE AND SERVICES PROVIDED BY
NORTEL NETWORKS PURSUANT TO THIS AGREEMENT, AND CUSTOMER'S EXCLUSIVE REMEDIES IN
THE EVENT SUCH WARRANTIES ARE BREACHED. THEY ARE IN LIEU OF ALL OTHER WARRANTIES
WRITTEN OR ORAL, STATUTORY, EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION,
THE WARRANTY OF MERCHANTABILITY AND THE WARRANTY OF FITNESS FOR A PARTICULAR
PURPOSE.

supplied hereunder) and shall pay all fines or penalties that may be assessed or
levied by the applicable governmental authority for noncompliance with respect
to such Regulatory Claim or as are agreed to by Nortel Networks in settlement of
such Regulatory Claim. All such losses, claims, demands, and damages, or fines
or penalties shall be paid directly by Nortel Networks. Notwithstanding anything
to the contrary contained in this Agreement, the Customer Indemnified Parties
shall have the right, in their sole discretion, to implead, interplead or

of the performance of Customer's obligations pursuant to this Agreement. All
such losses, claims, demands, and damages shall be paid directly by Customer.
Notwithstanding anything to the contrary contained in this Agreement, the Nortel
Indemnified Parties shall have the right, in their sole discretion, to implead,
interplead or otherwise cause Customer to be added as a party to any action or
proceeding brought against a Nortel Indemnified Party relating to any matter or
thing for which such Nortel Indemnified Party is entitled to indemnification
pursuant to this Section 12.2 and, if in any such proceeding Customer is found
to be liable, Customer shall be responsible for all liabilities and damages
assessed against it in any such proceeding or action.

Customer or Nortel Networks in accordance with Sections 12.1 and 12.2 above, the
Customer Indemnified Party and the Nortel Indemnified Party, as applicable,
shall (a) give Customer or Nortel Networks, as applicable, prompt written notice
of any such loss, claim, demand, damage or cause of action or Regulatory Claim;

the indemnification to be provided hereunder except to the extent that Customer
or Nortel Networks, as applicable, shall have been actually prejudiced as a
result of such failure, (b) allow Customer or Nortel, as applicable, to

that Customer shall be entitled to control of the defense or settlement of any
Regulatory Claim with respect to matters that do not involve monetary damages
(with reasonable participation by Nortel Networks, at its own cost and expense),
and shall have the right to settle or compromise any Regulatory Claim to the
extent that it involves anything other than money damages without the prior
consent of Nortel Networks, and (c) reasonably cooperate with Customer or Nortel
Networks, as applicable, in such defense and any related settlement
negotiations; provided however, that the applicable Customer Indemnified Party
or Nortel Indemnified Party shall be reimbursed by Customer or Nortel Networks,
as applicable, for its actual, reasonable, out-of-pocket costs for such
reasonable cooperation.

         12.4     Except as provided in, or for liabilities arising under,
Articles 7, 15 and 19 and Section 12.1 with respect to bodily injury and damage
to tangible property, or for claims regarding title to Equipment or Software,

non-binding forecast of the applicable items that Customer anticipates
purchasing or licensing over the next six (6) months. In addition to the type,

                            SERVICE AND SUPPORT PLAN

         Nortel Networks shall make available to Customer, as, when and if
ordered by Customer, for a period of three (3) years after expiration of the
Term, a Service and Support Plan. The terms of the Service and Support Plan
during the Term are attached hereto as Attachment C. The terms of the Service
and Support Plan for the three (3) year period after the expiration of the Term
shall be no less favorable to Customer than the terms of the Service and Support
Plans made generally available to Nortel Networks' customers at such time. The
prices for the Service and Support Plan during the Term are set forth in
Attachment C and are no less favorable to Customer than Nortel Networks' current
standard rates.

                                PATENT INDEMNITY

         15.1     Nortel Networks will defend, at its own expense, all suits and
claims made or brought by a third party against Customer and/or its Affiliates,
wherever such suit or

                                       42

<PAGE>

claim is commenced or asserted, for infringement or violation of any patent,
trademark, copyright, trade secret, or other tangible or intangible property
rights of any kind whatsoever (collectively, "Property Rights") of such third
party, covering, or alleged to cover, the Equipment, Software, or the System or
any component thereof, excluding Reseller Items, or the use thereof in the
Territory, in the form furnished or as subsequently modified by Nortel Networks
(and not modified by Customer or any other person without the written consent of
Nortel Networks), and Nortel Networks will pay all sums, including attorneys'
fees and expenses and other costs which, by final judgment or decree, or in
settlement of any such suit or claim, may be assessed against Customer or its
Affiliates on account of such infringement or violation, provided (a) Nortel
Networks shall be given prompt written notice of all claims of any such
infringement or violation and of any suits or claims brought or threatened
against Customer or its Affiliates of which Customer or such Affiliate has
express knowledge; provided that a failure to give such prompt notice shall not
affect the indemnification to be provided hereunder except to the extent that
Nortel Networks shall have been actually prejudiced as a result of such failure;
(b) Nortel Networks shall be given full authority to assume the sole defense
thereof through its own counsel at its own cost and expense and to compromise or
settle any suits or claims so far as this may be done without prejudice to the
right of Customer to continue the use, as contemplated, of the Equipment,
Software or the System or any component thereof so furnished, subject to Section
15.2; (c) Customer shall cooperate fully with Nortel Networks in the defense of
such suit or claims and provide Nortel Networks such assistance as Nortel
Networks may reasonably require in connection therewith; provided, however, that
Customer shall be reimbursed by Nortel Networks for

                                       43

<PAGE>

its actual, reasonable, out-of-pocket costs for such reasonable cooperation; and
(d) use of such Equipment, Software, System or component was at all times within
the Territory.

         15.2     If in any such suit so defended all or any part of the
Equipment, Software, or the System or any component thereof is held to
constitute an infringement or violation of any third party's Property Rights, or
if in respect of any claim of infringement or violation Nortel Networks deems it
advisable to do so, Nortel Networks shall, at its sole option and expense, use
its commercially reasonable best efforts to take one or more of the following
actions: (a) procure the right for Customer to continue the use of the same
without interruption, (b) replace the same with non-infringing Equipment or
Software or components (which Equipment, Software or components shall be
equivalent as to form, fit and function) with as minimal interruption of use as
is practicable (and any such interruption shall not be during Customer's peak
hours) provided that such replacement shall not adversely impair the System,
Equipment or Software from performing in accordance with all material
performance Specifications, or (c) modify such Equipment or Software or
component so as to be non-infringing Equipment or Software or components with as
minimal interruption of use as is practicable (and any such interruption shall
not be during Customer's peak hours) provided that the modified non-infringing
Equipment or Software or components shall not adversely impair the System,
Equipment or Software from performing in accordance with all material
performance Specifications. In the event that, despite Nortel Networks'
commercially reasonable best efforts, none of subsections (a), (b) or (c) can be
performed by it, then Nortel Networks shall have the right to take back the
infringing item(s) and give Customer a credit equal to Customer's net aggregate
purchase price for such item(s), if such return occurs during the

                                       44

<PAGE>

Term and, commencing upon the first day after the expiration of the Term, less
depreciation of twenty (20%) percent of such purchase price for each year of use
thereof after expiration of the Term. To the extent that the return of any such
infringing item in accordance with the previous sentence prevents or adversely
impairs Customer's use or operation of other items of Equipment or Software,
Customer's right to receive a credit shall apply to the net aggregate purchase
price of such other items, less depreciation, if applicable, as well.

         15.3     The indemnity provided in this Article 15 shall not extend to
infringement of Property Rights to the extent that such infringement arises from
(a) modifications made to Equipment or Software by Nortel Networks in order to
adhere to special Equipment or Software design requests, specifications or
instructions of Customer but only if such alleged infringement would not have
resulted from Nortel Networks' design prior to Customer's requested
modification, (b) use of the Equipment, Software or System or any component
thereof in a manner or for a purpose not stated in the Specifications or in a
manner or for a purpose not reasonably contemplated by Nortel, (c) use of the
Equipment, Software or System in combination with any other equipment or
software not supplied by Nortel Networks hereunder, (d) the incorporation of
components not manufactured or provided by Nortel Networks into the Equipment or
Software, (e) Customer originated modifications to the Equipment or Software
(unless expressly permitted by Nortel Networks in writing), or (f) Customer's
failure to install or have installed changes, revisions or updates required to
be installed by Nortel Networks in order to prevent such infringement.

<PAGE>

         15.4     Nortel Networks' Property Rights indemnification
responsibilities under this Article 15 shall not be applicable to Reseller Items
provided to Customer pursuant to this Agreement. With respect to Reseller Items,
any Property Rights indemnification provided to Nortel Networks by the third
party vendor supplying the applicable Reseller Item shall inure, to the extent
applicable or permitted, to the benefit of Customer, and Customer shall have the
right to enforce such indemnification directly with the third party providing
the applicable Reseller Item to Nortel Networks (or, if Customer is not
permitted to enforce such indemnification directly, Nortel Networks shall
enforce such indemnification on behalf of Customer).

         15.5     The preceding represents Customer's sole and exclusive remedy
regarding any claim of infringement or violation of Property Rights.

                                   ARTICLE 16
                        CHANGE ORDERS; ORDER CANCELLATION

         16.1     The terms and conditions of any Purchase Order, including the
provisions of the applicable Statement of Work, may be amended by mutually
agreed Change Orders ("Change Orders"). Each Change Order must be in writing,
must identify the changes to be made and must be signed by the duly authorized
representatives of each of Nortel Networks and Customer.

         16.2     Unless otherwise expressly agreed in a written document signed
by both parties hereto, any Purchase Order, acknowledgment form or other form
issued by Customer or Nortel Networks containing terms and conditions of sale
shall not have the effect of modifying the terms and conditions of this
Agreement, notwithstanding any act of Customer and payment therefor, and all
deliveries and Installation of goods and

                                       46

<PAGE>

performance of services by Nortel Networks shall be deemed to be only upon the
terms and conditions of this Agreement.

         16.3     Customer, upon at least twenty-one (21) days prior notice to
Nortel Networks, may issue "holds" on Purchase Orders or suspend performance
under this Agreement, in whole or in part, at no additional cost to Customer
except as otherwise provided in this Section 16.3. If Customer issues a hold or
suspends performance for a period longer than ten (10) Business Days, Customer
will compensate Nortel Networks for any actual, reasonable, out-of-pocket costs
incurred by Nortel Networks due to such hold or suspension after such ten (10)
Business Day period. If any Purchase Order is placed on hold or is suspended for
a period of ninety (90) days or greater, it shall be deemed automatically
cancelled and shall be subject to the payment of any cancellation fees as set
forth below. In the event that Customer suspends performance, Customer and
Nortel Networks will mutually agree on a date to reconvene such performance or
if Customer does not elect to reconvene such performance, Nortel Networks shall
invoice Customer for Services actually performed and Customer shall pay such
invoice in accordance with Article 4.

         16.4     Customer may cancel any Purchase Order or portion thereof
prior to the shipment of the items comprising such Purchase Order or portion
thereof. No cancellation fee shall be payable by Customer with respect to
Purchase Orders for CDMA, TDMA, AMPS and GSM Software. With respect to the
cancellation of Purchase Orders for Equipment that has been engineered or
customized by Nortel Networks specifically for Customer's use or operation,
Customer shall pay Nortel Networks a cancellation fee based upon the number of
days prior to the scheduled shipping date that

                                       47

<PAGE>

Nortel Networks receives the cancellation notice from Customer. Such
cancellation fee shall be in accordance with the following table:

                              SOFTWARE RIGHT-TO-USE

         17.1     The rights and obligations of Customer and Nortel Networks
with respect to the Software Right-to-Use are contained in this Agreement and in
the Software Right-To-Use Agreement attached hereto as Attachment G. Nortel
Networks represents that the Software licensed by Customer hereunder is all of
the Software which Customer shall require to provide the features and
functionality set forth in the Specifications for such Software, and that
Customer shall not be required to license additional Software in order to
realize the benefit of such features and functionality, with the exception of
Software prerequisites identified in the Documentation or unless otherwise
indicated in a written

proposal or quotation provided to Customer prior to the issuance of the
applicable Purchase Order for the applicable Software.

         17.2     In addition to the rights and obligations described in Section
17.1, Nortel Networks agrees to the following:

                  (a)      If TDMA, CDMA, GSM or AMPS Software or any part
thereof is lost or damaged (other than due to the fault of Customer) before
being Accepted or put In-Service, Nortel Networks will promptly replace it at no
additional cost to Customer. Any such Software lost or damaged after Acceptance
or due to the fault of Customer shall be replaced by Nortel Networks at a charge
to Customer equal to Nortel Networks' actual cost for gathering such Software.
Any Software which is not TDMA, CDMA, GSM or AMPS Software, or which is a
Reseller Item, that is lost or damaged for any reason shall be replaced by
Nortel Networks at a charge to Customer equal to Nortel Networks' actual cost
for gathering such Software.

                  (b)      If Nortel Networks modifies and/or changes the
Software to permit additional features and such features are made generally
available to its customers in the Territory, such Software will promptly be made
available to Customer at Nortel Networks' then current price for such features,
less applicable discounts and incentives as provided in Attachments A and B.

                           NON-DISCLOSURE OF TECHNICAL
                       INFORMATION AND PROPRIETARY RIGHTS

         18.1     Either party (hereafter the "Disclosing Party") may disclose
to the other party (hereafter the "Receiving Party") information which the
Disclosing Party considers proprietary and confidential. Accordingly, with
respect to any confidential or proprietary specifications, drawings, sketches,
models, samples, tools, technical information,

                                       50

<PAGE>

confidential business information or data which is furnished by the Disclosing
Party to the Receiving Party in contemplation of or under this Agreement
(hereinafter "Information"), the Receiving Party shall treat such Information as
confidential information with the same degree of care as the Receiving Party
affords to confidential information of its own of a similar nature.

         18.2     The provisions of this Article 18 shall not apply to any
Information which (a) is or shall become publicly available without fault on the
part of the Receiving Party; (b) is already known by the Receiving Party prior
to receipt from the Disclosing Party (so long as such Information was rightfully
obtained and is not subject to any other confidentiality agreement); (c) is
rightfully obtained by the Receiving Party from third parties without
restrictions; (d) the Receiving Party is required by law or by a governmental
authority or agency to disclose such Information, or (e) is independently
developed by a Receiving Party without any direct or indirect use of such
Information.

         18.3     In the event that the Receiving Party becomes obligated to
disclose Information pursuant to an order of any governmental or other
authority, the Receiving Party shall advise the Disclosing Party and, if
requested by the Disclosing Party and at the Disclosing Party's sole cost and
expense, seek a protective order or other appropriate remedy that will permit
the Receiving Party to avoid such disclosure. In the event that such protective
order or other remedy is not obtained, the Receiving Party will disclose only
that portion of the Information as it is obligated to disclose pursuant to such
order, and will use all reasonable efforts, at the Disclosing Party's sole cost
and expense, to obtain assurances that confidential treatment will be accorded
to any Information so disclosed.

generally availability of any version of the applicable Equipment or the
applicable Software Release within the Territory, (b) not apply to Reseller
Items, and (c) not apply if Nortel Networks offers another existing or new
product providing the same or substantially the same functionality as the

Customer shall grant Nortel Networks reasonable access to such sites for such
removal and clean-up.

         26.5     Nortel Networks shall be responsible for the supervision and
direction of all work performed by its subcontractors hereunder using Nortel
Networks' professional skill and attention. Nortel Networks shall be responsible

of Nortel Networks' subcontractors hereunder and that no subcontractor has any
right to impose a lien or security interest with respect to any Equipment
furnished to Customer hereunder or any Installation Services provided to
Customer hereunder. The duties, obligations, liabilities and responsibilities of
Nortel Networks under this Agreement shall continue in full force and effect and

termination, cancellation or suspension of any agreement between Nortel Networks
and any of its subcontractors or as a result of any default, breach or violation
on the part of Nortel Networks or any of its subcontractors under any agreement
or arrangement between Nortel Networks and any such subcontractor.

information to interface with the System as specified in Section 28.4 above.

Equipment or Software or who will be developing interfaces in order to
accomplish interconnectability as described in Section 28.4 above. Nortel
Networks agrees, at the request of Customer, to reasonably cooperate with
Customer or any third party to permit and accomplish such interconnection.
Nortel Networks agrees to provide Customer, as promptly as reasonably

specifications and upon completion of such new, or changed, specifications to
provide such to Customer, subject to Sections 28.4 and this 28.5.

Nortel Networks' right to receive any monies ("Receivables") so long as Nortel

                           GOVERNING LAW - ARBITRATION

         38.1     THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF THE STATE OF NEW YORK, UNITED STATES OF AMERICA
APPLICABLE TO CONTRACTS MADE AND TO BE ENTIRELY PERFORMED THEREIN.

         38.2     Subject to Section 38.3(b), and any provisions regarding
equitable relief contained herein, any dispute regarding any right, obligation,
duty or liability which may arise between the parties under this Agreement which
cannot be settled between them, shall be settled in accordance with this Article
38. Any such dispute shall be formally commenced upon the sending of written
notice from one party to the other specifying the

                                       76

<PAGE>

nature of such dispute and requesting the escalation of such dispute in
accordance with this Article 38. After the giving of such notice (and the
receipt thereof by the other party), each of the parties shall appoint a
representative from its senior management team and such appointed
representatives shall meet and negotiate in good faith in order to resolve such
dispute. The location, form, frequency, duration and conclusion of any such
negotiations shall be left to the discretion of the appointed representatives;
provided, however, that each of the parties shall have the right to submit such
dispute to arbitration in accordance with Section 38.3 below if such
negotiations are still ongoing after the expiration of sixty (60) days from the
date the initial notice was given (unless the parties mutually agree to extend
such time period). The representatives may, by mutual agreement, elect to
utilize alternative dispute resolution procedures (including mediation) in order
to assist in the negotiations. Such negotiations (and all correspondence
relating thereto) between the representatives shall not be admissible in any
arbitration proceeding commenced in accordance with this Article 38 unless
otherwise expressly agreed upon in writing by each of Customer and Nortel
Networks; provided, however, that documents identified in, referred to in or
provided in conjunction with any such correspondence between the representatives
(other than documents prepared solely for purposes of the negotiations) shall
not be subject to the preceding restriction on admissibility and may be admitted
into evidence in any such arbitration proceeding.

         38.3     (a)      In the event that a dispute is submitted to
arbitration in accordance with this Article 38, such dispute shall then be
settled by arbitration in accordance with the Rules of Arbitration of the
American Arbitration Association (AAA) in New York, New York, by three (3)
arbitrators, one (1) to be appointed by each party and the third to

                                       77

<PAGE>

be selected by the arbitrators appointed by the parties (provided that, if the
two (2) arbitrators appointed by the parties hereto cannot agree on the third
arbitrator, the third arbitrator shall be selected by the President of the AAA)
and shall be conducted in accordance with such Rules. Any fees charged by the
arbitrators or the AAA for arbitration services shall be shared equally by
Nortel Networks and Customer.

                  (b)      This Article 38 shall not be applicable to any
matters relating to either party's intellectual property rights (including
Article 15 hereof), misuse of Information (as set forth in Article 18) or
enforcement of the Software Right-to-Use set forth in Attachment G and neither
party shall be obligated to arbitrate such matters.

                  (c)      The award of any arbitration shall be final,
nonappealable, conclusive and binding on the parties hereto.

                  (d)      The arbitrators may award any legal or equitable
remedy, but if specific remedies or limitations on remedies are provided for in
this Agreement, they shall enforce such remedies or limitations on remedies. The
arbitration award may, at the discretion of the arbitrators, include an award of
attorneys' fees, and the amount of such fees, to the prevailing party. Judgment
upon any arbitration award may be entered and enforced in any court of competent
jurisdiction.

                  (e)      Either party to an arbitration hereunder may bring an
action for injunctive relief against the other party if such action is necessary
to preserve jurisdiction of the arbitrators or to maintain status quo pending
the arbitrators' decision. Any such action commenced pursuant to this Section
38.3 shall be discontinued upon assumption of jurisdiction by the arbitrators
