acknowledge and agree that nothing contained in this Agreement (including
without limitation this Section 2.5.1) shall require either Party to provide GSM
(or other technology except TDMA and analog cellular)-based roaming services,
preferential or otherwise, to the Customers of the other Party, even if any such
Customer owns or is using a handset which permits the handling of both TDMA- or
analog cellular-based and GSM-based communications services.

TDMA-based system, including all Core Features, (ii) (with respect to the System
of the Serving Carrier contained in such market) be fully interoperable in
accordance with Sections 10.6, 10.7, and 10.8, and (iii) otherwise have met, and
be in compliance with, all terms and conditions of this Agreement.

         2.6 ACC shall join and remain a member of the North American Cellular
Network throughout the term of this agreement.

indemnifying person, and (iv) the indemnified person shall not settle or
compromise any such claim without the prior written consent of the indemnifying
person.

         6.4 [RESERVED]

         6.5 Upon the implementation of wireless number portability in any
portion of either the AWS TDMA system or the ACC TDMA system, the parties shall
cooperate in establishing an alternative method for exchanging ESN and/or
NPA/NXX information required to permit roaming by the other party's customers in
their respective systems.

                                  Article VII.

                                      Fraud

         7.1 The parties will cooperate and, as necessary, supplement this
agreement in order to minimize fraudulent or other unauthorized use of their
systems. If any party reasonably decides that, in its sole judgment, despite due
diligence and cooperation pursuant to the preceding sentence, fraudulent or
other unauthorized use has reached an unacceptable level of financial loss and
is not readily remediable, such party may suspend the use of applicable NPA/NXX
combinations, in whole or in part, pursuant to the terms of this agreement.

         7.2 Each party shall take reasonable actions to control fraudulent
roamer usage, including without limitation using either (i) a positive
validation/verification ("PV") system provided by a mutually agreed upon
validation/verification service under which the ESN and/or NPA/NXX used in a
call in the serving carrier's system is compared against a list of authorized
roamers or (ii) SS-7 connections through a network of carriers. The parties
shall work together in good faith to designate and implement a system as
specified in the preceding sentence and enhancements thereto or alternative
systems as they shall agree in the future. The home carrier shall have no
responsibility or liability for calls completed by a serving carrier without
obtaining positive validation/verification as required herein.

         7.3 In addition to other procedures set forth in this agreement, a home
carrier may notify a serving carrier by facsimile, with written confirmation,
that certain NPA/NXX combinations are not to receive service. Any calls
completed using such NPA/NXX combinations made one full business day or more
after such notice has been given shall be the sole responsibility of the serving
carrier, and the home carrier shall not be charged any amount for such calls.

         7.4 Each serving carrier shall use commercially reasonable efforts to
provide each home carrier with real-time visibility of call detail records
delivered through a network compatible with AWS'S network. Such information
shall be delivered within one hour of the applicable call. In the event that the
serving carrier provides such a real-time visibility system, the serving carrier
shall not be liable in any event for a temporary failure of the system unless
the serving carrier has been notified of such failure by the home carrier and
the serving carrier does not take commercially reasonable steps to remedy the
failure. If the serving carrier has been so notified and has failed to take such
commercially reasonable steps, the serving carrier shall be liable for all
unauthorized usage attributed to home carrier's subscribers during the period
from the time serving carrier was notified of the problem to the time that the
problem has been resolved to the reasonable satisfaction of the home carrier.

         7.5 For purposes of notification under this Article VII, the following
addresses and facsimile numbers shall be used:

                                  Article VIII.

                                     Billing

         8.1 Each home carrier shall be responsible for billing to, and
collecting from, its own customers all charges that are incurred by such
customers as a result of service provided to them as authorized roamers by the
serving carrier. The home carrier shall also be responsible for billing its
customers for, and remitting to, the federal government all federal excise tax
that may be due in connection with the service being billed by it to its
customers. While the serving carrier will be responsible for the computation and
remittance of all state and local taxes, each home carrier shall be liable to
the serving carrier for all such state and local taxes remitted by the serving
carrier, for authorized roamers regardless of whether these amounts are paid to
the home carrier by its customers.

         8.2 Each serving carrier who provides service to an authorized roamer
pursuant to this agreement shall forward roamer billing information, within five
business days of the call date, in accordance with the procedures and standards
set forth in the Ciber record to the home carrier's authorized receipt point.
Ciber Type 50 and Ciber Type 70 records shall not be accepted without mutual
signed agreement and if such mutual agreement is reached it will be attached to
this agreement. Any future revisions of the Ciber record or additional record
types must be mutually agreed upon before implementation. In the event the
parties use the Cibernet Net Settlement Program, or alternative settlement
program such information must be in a format in compliance with the Ciber record
requirements or agreed upon format.

         8.3 Where the authorized roamer billing information required to be
provided by the serving carrier in accordance with Section 8.2 above is not in
accordance with



                                       14
<PAGE>
The ciber record, the home carrier may return a record to the serving carrier as
provided in the ciber record. Returning the defective record will be in
accordance with ciber record established procedures. The serving carrier may
correct the defective record and return it to the home carrier for billing,
provided that the time period from the date of the service call at issue to the
receipt of the corrected record does not exceed sixty (60) days.

         8.4 No credit for insufficient data or defective records shall be
permitted except as provided in section 8.3 above, unless mutually agreed upon
by both parties.

         8.5 Each home carrier may at its discretion perform any necessary edits
at its clearinghouse on incollect or outcollect call records to ensure
compliance with the terms of this agreement.

                                   Article IX.

                                   Settlement

         9.1 Each party will settle its accounts with the other parties on the
basis of billing information received as described in this Article IX. In the
event both parties use a net financial settlement procedure, the parties shall
not submit a paper invoice but will make payments in accordance with such net
financial settlement procedure provided that the parties may submit call records
for payment that relate to calls made more than sixty (60) days from the date of
the call if such call was the subject of a dispute or investigation regarding
fraudulent or unauthorized use.

         9.2 If an incorrect roaming rate is charged by the serving carrier to
the home carrier, the serving carrier shall refund all amounts in excess of the
contract rate back to the home carrier within forty five days of notification by
the home carrier. Each carrier shall have ninety (90) days from the end of the
settlement period to invoice for amounts in excess of the contract rate. The
home carrier will send a collection letter within sixty (60) days of the invoice
date, within ninety (90) days of the invoice date, and within one hundred (120)
days of the invoice date. If the invoice remains unpaid after one hundred twenty
(120) days from the original invoice date, the home carrier may withhold the
amounts from the cibernet net settlement program or alternative settlement
program.

         9.3 In the event that either party does not use a net financial
settlement procedure, the billing and payment for charges incurred under this
agreement shall be as set forth below.

                  9.3.1 The parties shall determine amounts owed to each other
for Service provided to Roamers in one-month periods with such period beginning
on the sixteenth day of each calendar month and ending on the fifteenth day of
the following month in which Service is provided. The end of this Period shall
be referred to as "Close of Billing."

<PAGE>
                  9.3.2 The Parties shall send each other an invoice for
Services used under this Agreement within fifteen (15) days after the Close of
Billing.

                  9.3.3 Each invoice shall contain the following information.

         a.       Billing period used by Serving Carrier

         b.       Batch sequence number

         c.       Serving and Home Carrier System Identification Number

         d.       Air Service charges

         e.       Total toll charges (both intrastate and interstate)

         f.       All other charges and credits

         g.       Total taxes

         h.       Total charges

                  9.3.4 Payment on such invoices shall be made in the form of a
check or a wire transfer which must be received by the invoicing party within
thirty (30) days from the date of the invoice. Late payments shall be charged
with a late payment fee of one and one half percent (1.5%) of the outstanding
balance for each thirty-day period (or portion thereof) that such payments are
late.

                  9.3.5 Each Party may offset the amount owed to the other Party
under this Agreement and a single payment of the balance to the Party entitled
to receive such balance shall be made.

         9.4 If the serving carrier provides pre-call validation of the home
carrier's customers, the home carrier agrees to implement negative file
suppression at the clearinghouse and the cibernet negative file guidelines and
procedures do not apply.

                                   Article X.

                      Interoperability and Other Agreements

         10.1 [Reserved]

                  10.1.1 Adopted Features shall be made available to all
Customers of a Party when roaming in the AWS TDMA System or the ACC TDMA System,
subject to the terms of this Agreement. Each Party shall use good faith efforts,
when implementing any software or other System change or upgrade, to confirm the
continued availability of the Feature interoperability provided for herein, and
in the event of any interference with any



                                       16
<PAGE>
Feature interoperability shall work expeditiously to restore required
functionality. Without limiting the generality of the foregoing, in the event
the Authentication Fraud Protection Feature (or any subsequent or comparable
fraud protection Feature) is disabled or affected by any network change so as to
interfere with its interoperability, the Party responsible for such network
shall restore interoperability within 48 hours of notification from the affected
Party.

                  10.1.2 [reserved]

                  10.1.3 [reserved]

                  10.1.4 Any entity listed on Schedule 1 but in which AT&T
Wireless owns, directly or indirectly, less than a majority interest or which
AT&T Wireless otherwise does not control shall, at the option of AT&T Wireless,
not be subject to the requirements of this Article X.

         10.2 [RESERVED]

                  10.2.1 ACC shall maintain its commitment to TDMA as ACC's
digital standard for the ACC TDMA System on Exhibit A for so long as, and to the
extent that, AWS maintains its commitment to TDMA as AWS's digital standard for
the AWS TDMA System. AWS agrees that in the event it may exercise its discretion
to no longer remain committed to TDMA as its digital standard for the AWS TDMA
System (it being understood that AWS may elect in its sole discretion at any
time to cease to employ TDMA in its business or operations), it shall give ACC
six months' prior notice of that decision. Upon the termination of AWS's
commitment to TDMA as its digital standard for the AWS TDMA System, the
following Sections of this Agreement shall immediately terminate: Sections 10.1,
10.2 and 10.3.

                  10.2.2 Subject to Section 10.2.1, ACC shall deploy TDMA
throughout the ACC TDMA System during the term of this Agreement.

         10.3 Each of the parties agrees that it shall operate and support its
tdma-based system, to the extent installed, to ensure that the other party's
customers can use the adopted features when roaming on the serving carrier's
tdma-based system in the same manner that such customers use such adopted
features on the home carrier's tdma-based system.

                  10.3.1 Core Features. Each Party shall, at its own expense,
implement the Core Features in the AWS TDMA System, in the case of AWS, and in
the ACC TDMA System, in the case of ACC, as soon as reasonably practicable and
in any event within one (1) year after the Effective Date. Thereafter, Core
Features shall be implemented at the time any TDMA-based system is placed into
operation.

                  10.3.2 Future Core Features. The Future Core Features shall be
those features set forth on Schedule E-2 to Exhibit E attached hereto or that
are agreed upon by the Parties from time to time after the execution of this
Agreement. Each Party shall, at its own expense, implement such Future Core
Features within one (1) year after the General Availability of such Future Core
Features, provided that, and subject to such Party's determination, in its sole
and absolute discretion, that such implementation is both financially



                                       17
<PAGE>
feasible and economically viable, and consistent with such Party's objective of
maximizing its financial performance. In the event that a Party opts not to
adopt a Future Core Feature in accordance with this Section 10.3.2, it shall
promptly notify the other Party of that decision. Future Core Features shall be
implemented in accordance with this Section in the areas specified for each
respective Party in Section 10.3.1.

                  10.3.3 Additional Features. In addition to the Core Features
and the Future Core Features, ACC shall offer, at the request of AWS, additional
service features that AWS notifies ACC that AWS will provide in a majority of
its TDMA Systems, unless ACC reasonably determines that providing such
additional features would be financially detrimental to ACC. Absent such
determination, any such additional features shall be adopted within 120 days (or
such longer period as is reasonably necessary under the circumstances) after the
request by AWS. ACC agrees that in order to offer certain Additional Features it
will be obligated to implement technological enhancements, upgrades,
improvements and advances ("Improvements") that are implemented by AWS from time
to time and that are technologically compatible with ACC's equipment. At the
request of AWS, ACC will implement any Improvements that AWS notifies ACC that
AWS will implement in a majority of its TDMA Systems, unless ACC reasonably
determines that the implementation of any such Improvement would be financially
detrimental to ACC. Absent such determination, any such improvements shall be
implemented within 120 days (or such longer period as is reasonably necessary
under the circumstances) after the request by AWS. A course of action will be
considered "financially detrimental" to ACC for purposes of this Section 10.3.3
if the reasonable business case for such course of action has a net present
value that is less than or equal to negative 10% of the capital cost of that
course of action.

                  10.3.4 The Parties shall use commercially reasonable efforts
to comply with the network performance standards with respect to the Adopted
Features that are set out in Schedule E-3 to Exhibit E attached hereto.

         10.4 Neither Party shall provide the other Party's customers with
service inferior in quality to that provided to its own customers. Each Party
shall provide service to customers of the other Party of a quality level, based
on criteria customarily used to evaluate the performance of wireless voice
systems, comparable to or exceeding industry norms. Any assessment of "Quality"
shall be with reference to the system's performance as a whole within a specific
MSA, RSA, or BTA, as the case may be, and shall be over such a period of time as
reasonably necessary to yield an accurate depiction of system "Quality" taking
into account all of the variables which may affect system performance.

         10.5 In order to facilitate performance by each of the parties of their
obligations under this Article X, the Parties agree to exchange and share
information with each other as follows, except that nothing contained herein
shall be construed to require a Party to exchange information that the Party
considers confidential or proprietary.

                  10.5.1 Subject to Article XVII of this Agreement, the Parties
shall provide each other, on a reasonably prompt basis, with all information and
materials that



                                       18
<PAGE>
either has a right to disclose that is necessary to meet the interoperability
standards set forth in this Article X, including without limitation the
following information:

         System Engineering:

                  o        Minimum Standards for Systems

         Features:

                  o        Capability description of present Core Features and
                           other Features

                  o        User Interface (codes)

                  o        Implementation procedures

                  o        Roaming requirements

                  o        Feature functionality design documents

                  Research and Development:

                  o        operational test results

                  o        operational defects and bugs

                  o        remedial/back-up plans

                  o        operational, functional and technical specifications

                  o        all related documentation

                  o        systems integration

                  10.5.2 Each Party agrees that it shall, in performing its
obligations to provide the other Party with information in accordance with this
Section 10.5, act reasonably, and in good faith toward the other Party.

                  10.5.3 Nothing contained herein is intended or should be
construed to constitute the transfer or grant by one Party to the other of any
ownership, license, or other rights of or to any trade secret, know-how, or
other intellectual property by one Party to the other.

         10.6 Each Party shall provide for automatic call delivery for customers
of the other Party who are roamers in such Party's system. To this end, each
Party shall continuously provide the hardware, software and transmission
facilities required for such call delivery either directly between the systems
of the Parties or indirectly through a separate network of wireless
communications carriers. The hardware, software and transmission facilities
provided by each Party hereunder shall at all times be operated and maintained
to provide the most efficient level of service that is technically feasible and
commercially reasonable to minimize transmission errors and service
interruptions.

         10.7 If the Parties have implemented linking facilities as contemplated
in Section 10.8, the serving carrier shall automatically hand-off to the home
carrier, and as requested shall automatically accept hand-off from the home
carrier in order to



                                       19
<PAGE>
provide service as specified in Article II, calls to or from a customer of the
home carrier in accordance with the hand-off procedures established for such
linking facilities. To this end, each Party shall continuously provide the
hardware, software and transmission facilities required for such call hand-off
either directly between the systems of such home and serving carrier or
indirectly through a separate network of wireless communications carriers. The
hardware, software and transmission facilities provided by each Party hereunder
shall at all times be operated and maintained to provide the most efficient
level of service that is technically feasible and commercially reasonable to
minimize transmission errors and service interruption.

         10.8 The Parties will work together to evaluate the economic advantage
of various switch linking options to interconnect and facilitate networking of
the Parties' respective systems as required by this agreement. Should the
Parties agree to install and maintain linking facilities, the cost of the
linking facilities shall be allocated pursuant to the following provisions:

                  10.8.1 AWS and ACC will each pay one-half of the equipment
costs for the establishment of microwave facilities to link the Parties'
respective Systems for the purposes of automatic call delivery and automatic
call hand-off. Each Party is solely responsible for the costs of preparing its
own facilities for the System link.

                  10.8.2 Equipment costs for the establishment of a landline
link (T-1) to link the Parties' respective Systems together for these purposes
shall be split between the Parties as follows:

         (a) AWS and ACC shall each pay one-half of the cost for the
installation, use, modification, or discontinuance of the linking facilities.
Each party is solely responsible for all costs to prepare its own facilities for
the link between the Systems.

         (b) For ease of administration, AWS will order and be the customer of
record ("COR") for such facilities. ACC will reimburse AWS monthly for its share
of the recurring costs of such facilities. The COR shall be responsible for
invoicing the other Party for its share of the costs, with payment due within 30
days of receipt of the invoice.



                                       20
<PAGE>
                  10.8.3 The Parties agree that this Section 10.8 relates only
to those costs necessary to establish the referenced facilities. This section is
not applicable to the allocation of costs with respect to the provision of
service for each Party's Customers.

         10.9 The Parties agree that the revenues and costs for a call belong to
the Party whose system operates the originating cell site (the "Bill and Keep
System").

         10.10 Except as provided in connection with a disqualifying
transaction, so long as ACC continues to meet its obligations hereunder in
respect of the adopted features and network performance standards (as described
under schedules E-1, E-2 and E-3) (Collectively, the "TDMA Quality Standards")
in all material respects, AT&T Wireless will not, and will not cause its
affiliates to, construct, own or acquire a controlling interest in, or manage a
communications system which provides mobile wireless services in the territory
(other than the KY-04 RSA, KY-05 RSA, KY-06 RSA AND KY-08 RSA Markets), except
that AT&T Wireless may:

         (a) [reserved]

         (b) [reserved]

         (c) continue to act as an agent for other Mobile Wireless Services
carriers in the Territory solely for existing national account customers who are
served by that carrier and request that they continue to receive service from
that carrier; and

         (d) [reserved]

         (e) subject to the provisions of the following sentence, acquire, hold,
maintain and renew FCC licenses and mobile wireless telecommunications
facilities, to the extent necessary or advisable to maintain and renew such
licenses, including compliance with the construction requirements, and
satisfaction of the substantial service requirement for license renewal
expectancy, of applicable FCC rules, and ACC shall cooperate with AWS, at AWS's
request and expense, in connection therewith. AWS will give ACC reasonable
advance written notice of deadlines relating to construction and substantial
service requirements with respect to each license held by AWS or its
subsidiaries in the Territory. ACC will have 15 days from receipt of any such
notice to elect in writing to comply with such requirements on behalf of AWS. If
ACC



                                       21
<PAGE>
makes such election with respect to a license, the parties shall promptly
execute and deliver mutually satisfactory agreements providing for such
compliance, in substantially the form of comparable agreements that previously
have been entered into by the parties or their respective Affiliates.

                  10.10.1 [reserved]

         10.11 [reserved]

         10.12 [reserved]

         10.13 [reserved]

         10.14 [reserved]

         10.15 AWS will notify ACC of the execution of definitive agreements
relating to a disqualifying transaction and will offer to sell, or (if AWS is
not the surviving entity) to arrange for the surviving entity to sell, any or
all of the competitive systems to ACC at their fair market value (the "ACC
Purchase"). ACC shall have 30 days from the receipt of such offer to elect to
purchase any or all of the competitive systems. If ACC elects to purchase one or
more of the competitive systems within such 30-day period, ACC will promptly
enter into a purchase and sale agreement on commercially reasonable terms with
AWS or the surviving entity. The consummation of the ACC purchase will be
scheduled to occur within a reasonable period of time following the consummation
of the disqualifying transaction. If ACC notifies AWS or the surviving entity
within such 30-day period that ACC would have elected to purchase one or more of
the competitive systems but for applicable FCC regulations prohibiting such
purchase (such competitive systems, the "FCC Affected Systems"), AWS or the
surviving entity will use commercially reasonable efforts to sell such
competitive systems to a third party at their fair market value. AWS shall cease
to be subject to the provisions of Sections 2.5 and 10.10 with respect to any
competitive systems acquired pursuant to a disqualifying transaction if (x) ACC
does not elect to purchase such competitive systems within such 30-day period or
(y) ACC fails to purchase such competitive systems in breach of the applicable
purchase and sale agreement or (z) in the case of FCC affected systems only, AWS
or the surviving entity is unable to agree with an unaffiliated third party to
sell such FCC affected systems within 180 days after the expiration of such
30-day period, and ACC shall have the right to terminate Section 2.5 of this
agreement with respect to the same portion of the territory. Following the
consummation of the disqualifying transaction and pending the disposition of any
competitive systems in accordance with the foregoing provisions of this Section
10.15, AWS shall be relieved of its obligations under Sections 2.5 and 10.10,
and ACC shall be relieved of its obligations under Section 2.5 this agreement,
with respect to such competitive systems and those portions of the



                                       22

territory in which such competitive systems are located. AWS will not expand,
within the territory, the footprint of any competitive system that it retains.

         10.16 [reserved]

         10.17 The Parties acknowledge and agree that, notwithstanding any other
term hereof, the provisions of Sections 10.10 and 10.15 shall not be effective
until the LLC termination date has occurred, whereupon such provisions shall
automatically become effective without any further actions required of the
Parties.

                                   ARTICLE XI.

                         REPRESENTATIONS AND WARRANTIES

         11.1 AWS HEREBY REPRESENTS AND WARRANTS TO ACC THAT:

                  11.1.1 AT&T Wireless is a corporation duly organized, validly
existing, and in good standing under the laws of the State of Delaware. AT&T
Wireless has all requisite power and authority to execute and deliver this
Agreement and to cause this Agreement to be the binding obligation, to the
extent provided herein, of those of its Affiliates listed on Schedule 1 or added
to Schedule 1 hereafter in accordance with Section 2.4.

                  11.1.2 This Agreement is the legal, valid, and binding
obligation of AT&T Wireless, enforceable against AT&T Wireless in accordance
with its terms, except that such enforceability may be subject to (a)
bankruptcy, insolvency, reorganization, moratorium, or other similar laws now or
hereafter in effect relating to creditors' rights generally and (b) equitable
principles of law and the discretion of any court or arbitral body before which
any related proceeding may be brought.

                  11.1.3 The execution, delivery, and performance of this
Agreement by AT&T Wireless does not and will not conflict with or result in a
material default, suspension, or termination of any agreement, contract,
obligation, license, or authorization with or granted by any third party or
governmental body.

         11.2 ACC HEREBY REPRESENTS AND WARRANTS TO AWS THAT:

                  11.2.1 ACC is a limited liability company duly organized,
validly existing, and in good standing under the laws of the State of Delaware.
ACC has all requisite power and authority to execute and deliver this Agreement
and to cause this Agreement to be the binding obligation, to the extent provided
herein, of those of its Affiliates listed on Schedule 2 or added to Schedule 2
hereafter in accordance with Section 2.4.

                  11.2.2 This Agreement is the legal, valid, and binding
obligation of ACC, enforceable against ACC in accordance with its terms, except
that such enforceability may be subject to (a) bankruptcy, insolvency,

                                       23
<PAGE>
and the discretion of any court or arbitral body before which any related
proceeding may be brought.

                  11.2.3 The execution, delivery, and performance of this
Agreement by ACC does not and will not conflict with or result in a material
default, suspension, or termination of any agreement, contract, obligation,
license, or authorization with or granted by any third party or governmental
body.

                                  ARTICLE XII.

                  TERM, TERMINATION AND SUSPENSION OF AGREEMENT

         12.1 This Agreement shall have a term commencing on the effective date
and continuing until February 25, 2020; provided, that the provisions of
Sections 2.5 and 10.10 (in each case except to the extent terminated earlier in
connection with a disqualifying transaction) and Section 10.15 shall terminate
on February 25, 2005. Thereafter, this Agreement shall continue in force on a
month-to-month basis unless either Party terminates the Agreement by written
notice to the other Party given at least 90 days prior to the date of
termination. Otherwise, this Agreement may be terminated or suspended only as
provided in this Article XII.

         12.2 This Agreement may be terminated or suspended by either Party
immediately upon written notice to the other of a default (as defined in Section
13.1) by the other Party. In addition, either Party may suspend this Agreement
immediately upon written notice to the other Party pursuant to Section 13.1.1 of
the existence of a breach of this Agreement, whether or not such breach
constitutes a default, which materially affects the service being provided to
customers of the non-breaching Party. While any suspension of this Agreement,
whether in part or in whole, is in effect, the obligations of the Parties shall
be only those that survive termination and to work together to resolve as
expeditiously as possible any difficulty that resulted in a suspension. At such
time as the Party originally giving notice of suspension concludes that the
problem causing the suspension has been resolved, that Party shall give to the
other written notice to this effect. This Agreement shall resume in full effect
within five (5) business days after the Parties have mutually agreed that the
problem has been resolved.

         12.3 The Parties shall cooperate to limit the extent and effect of any
suspension of this Agreement to what is reasonably required to address only the
cause of such suspension.

         12.4 In the event that a party transfers control of an Affiliate listed
in Schedule 1 or Schedule 2, as the case may be, the Party shall provide at
least four months' prior written notice to the other Party and upon such
transfer such Affiliate shall be deleted from the appropriate schedule, but
doing so will not relieve a Party of its obligations under Section 14.1.



                                       24
<PAGE>
         12.5 The termination or suspension of this Agreement shall not affect
the rights and liabilities of the Parties under this Agreement with respect to
all authorized roamer charges incurred prior to the effective date of such
termination or suspension.

                                  ARTICLE XIII.

                                     DEFAULT

         13.1 A Party will be in "default" under this Agreement upon the
occurrence of any of the following events:

                  13.1.1 Material breach of any material term of this Agreement,
if such breach shall continue for thirty (30) days after receipt of written
notice thereof from the non-breaching Party;

                  13.1.2 Voluntary liquidation or dissolution or the approval by
the management, board of directors, stockholders, or owners of a Party of any
plan or arrangement for the voluntary liquidation or dissolution of the Party;

                  13.1.3 A final order by the FCC revoking or denying renewal of
CMRS licenses or permits granted to such Party which, individually or in the
aggregate, are material to the business of such Party; or

                  13.1.4 Such Party (i) filing pursuant to a statute of the
United States or of any state, a petition for bankruptcy or insolvency or for
reorganization or for the appointment of a receiver or trustee for all or a
portion of such Party's property, (ii) has filed against it, pursuant to a
statute of the United States or of any state, a petition for bankruptcy or
insolvency or for reorganization or for the appointment of a receiver or trustee
for all or a portion of such Party's property, provided that within 120 days
after the filing of any such petition such Party fails to obtain a discharge
thereof, or (iii) making an assignment for the benefit of creditors or
petitioning for, or voluntarily entering into, an arrangement of similar nature,
and provided that such filing, petition, or appointment is still continuing.

         13.2 All claims and disputes relating in any way to the performance,
interpretation, validity, or breach of this Agreement, including but not limited
to a claim based on or arising from an alleged tort, shall be resolved as
provided in this Section 13.2. It is the intent of the Parties that any
disagreements be resolved amicably to the greatest extent possible.

                  13.2.1 If a disagreement cannot be resolved by the
representatives of the Parties with day-to-day responsibility for this
Agreement, such matter shall be referred to an executive officer of each of the
Parties. The executive officers shall conduct face-to-face negotiations at a
neutral location or such other location as shall be mutually agreed upon. If
these representatives are unable to resolve the dispute within ten business days
after either Party requests the involvement of the executive officers, then
either Party may, but is not required to, refer the matter to mediation or
arbitration, as applicable in accordance with Sections 13.2.2 and 13.2.3.



                                       25
<PAGE>
                  13.2.2 In any case where the amount claimed or at issue is One
Million Dollars ($1,000,000) or more and the Parties are unsuccessful in
resolving the disagreement, the Parties agree to submit the disagreement to
non-binding mediation upon written notification by either Party. The Parties
shall mutually select an independent mediator experienced in telecommunications
system disputes. The specific format for the mediation shall be left to the
discretion of the mediator. If mediation does not result in resolution of the
disagreement within thirty days of the initial request for mediation, then
either Party may, but is not required to, refer the matter to arbitration.

                  13.2.3 Any disagreement not finally resolved in accordance
with the foregoing provisions of this Section 13.2 shall, upon written notice by
either Party to the other, be resolved by final and binding arbitration. Subject
to this Section 13.2.3, such arbitration shall be conducted through, and in
accordance with the rules of, JAMS/Endispute. A single neutral arbitrator shall
decide all disputes. Each Party shall bear its own expenses with respect to the
arbitration, except that the costs of arbitration proceeding itself, including
the fees and expenses of the arbitrator, shall be shared equally by the Parties.
The arbitration shall take place in a neutral location selected by the
arbitrator. The arbitrator may permit discovery to the full extent permitted by
the Federal Rules of Civil Procedure or to such lesser extent as the arbitrator
determines is reasonable. The arbitrator shall be bound by and strictly enforce
the terms of this Agreement. The arbitrator shall make a good faith effort to
apply applicable law, but an arbitration decision and award shall not be subject
to review because of errors of law. The arbitrator shall have the sole authority
to resolve issues of the arbitrability of any disagreement, including the
applicability or running of any applicable statute of limitation. The arbitrator
shall not have power to award damages in connection with any dispute in excess
of actual compensatory damages nor to award punitive damages nor any damages
that are excluded under this Agreement and each party irrevocably waives any
claim thereto. The award of any arbitration shall be final, conclusive and
binding on the Parties. Judgment on the award may be entered in any court having
jurisdiction over the Party against which the award was made. Nothing contained
in this Section 13.2.3 shall be deemed to prevent either party from seeking any
interim equitable relief, such as a preliminary injunction or temporary
restraining order, pending the results of the arbitration. The United States
Arbitration Act and federal arbitration law shall govern the interpretation,
enforcement, and proceedings pursuant to the arbitration clause in this
Agreement.

                                  ARTICLE XIV.

                             SUCCESSORS AND ASSIGNS

         14.1 Neither party may, directly or indirectly, sell, assign, transfer,
or convey its interest in this agreement or any of its rights or obligations
hereunder, including any assignment or transfer occurring by operation of law,
without the written consent of both parties, except that (i) either party may
assign or delegate this agreement or any of its rights or obligations hereunder
to an affiliate of such party without the consent of the other party, but such
assignment or delegation will not relieve the party of any of its obligations
hereunder and (ii) a party may assign its rights and obligations hereunder to an
assignee of its service license or permit issued by



                                       26
<PAGE>
the FCC, provided that such assignee expressly assumes, by written instrument
approved in writing by the other party, all of the obligations of such party
hereunder and thereby becomes a party hereunder. In no event will an assignment
permitted under this Section 14.1 without the consent of the other party
obligate a serving carrier to provide service to customers of the assignee or
any of its affiliates other than customers residing in the area in which the
assignor previously was licensed to provide service.

         14.2 No person other than a party to this agreement or an indemnified
person shall acquire any rights hereunder as a third-party beneficiary or
otherwise by virtue of this agreement.

                                   ARTICLE XV.

                NO PARTNERSHIP OR AGENCY RELATIONSHIP IS CREATED

Nothing contained in this Agreement shall constitute the Parties as partners
with one another or render any Party liable for any debts or obligations of any
other Party, nor shall any Party hereby be constituted the agent of the other
Party.

                                  ARTICLE XVI.

                     NOTICES AND AUTHORIZED REPRESENTATIVES

Unless otherwise provided herein, any notice, request, instruction or other
document to be given hereunder by any Party to the other shall be in writing and

business day; and the next business day if sent by overnight air delivery
service.

                                  ARTICLE XVII.

                                 CONFIDENTIALITY

         17.1 Each Party shall, and shall cause each of its affiliates and each
of its and their employees, agents, and contractors, to keep confidential and
not use for any purpose except as contemplated by this agreement, any and all
information and know-how provided to it by the other Party which is identified
in writing as confidential ("confidential information"). Identification of
information as confidential shall, in the case of information delivered in
tangible form, appear on at least the face or first page of such information
and, in the case of information communicated verbally, be given verbally
contemporaneously with the delivery of the information and confirmed in writing
within five business days thereafter. Notwithstanding the foregoing, the
following information shall be treated as confidential information without any
further identification as such: (i) The terms, but not including the mere
existence, of this agreement; and (ii) all information exchanged pursuant to
Article VI.

         17.2 Notwithstanding Section 17.1, a Party shall have no obligation to
keep confidential any information that (a) was rightly in the receiving party's
possession before receipt from the disclosing Party, (b) is or becomes a matter
of public knowledge without violation of this agreement by the receiving Party,
(c) is rightfully received by the receiving Party from a third Party rightfully
in possession of and, to the best of the receiving Party's knowledge, with a
right to make an unrestricted disclosure of such information, (d) is disclosed
by the disclosing Party to a third Party without imposing a duty of
confidentiality on the third Party, or (e) is independently developed by the
receiving Party without the use of any confidential information. In addition, a
party may disclose any confidential information to the extent required by
applicable law or regulation or by order of a court or governmental agency;
provided, that prior to disclosure the Party shall use all reasonable efforts to
notify the other Party of such



                                       28
<PAGE>
pending disclosure and shall provide any reasonable assistance requested by the
other Party to maintain the confidentiality of the information.

         17.3 The Parties agree that a Party will not have an adequate remedy at
law in the event of a disclosure or threatened disclosure of confidential
information in violation of this Article XVII. Accordingly, in such event, in
addition to any other remedies available at law or in equity, a Party shall be
entitled to specific enforcement of this Article XVII and to other injunctive
and equitable remedies against such breach without the posting of any bond.

         17.4 The obligations under this Article XVII shall survive the
termination of this agreement for a period of three years.

                                 ARTICLE XVIII.

                                  MISCELLANEOUS

         18.1 The Parties agree to comply with, conform to, and abide by all
applicable and valid laws, regulations, rules and orders of all governmental
agencies and authorities, and agree that this agreement is subject to such laws,
regulations, rules and orders. All references in this agreement to such laws,
regulations, rules and orders include any successor provision. If any amendment
to or replacement of the same materially alters the benefits, rights, and duties
of the Parties hereunder, the Parties agree to negotiate in good faith an
amendment to this agreement to restore the respective positions of the Parties
to substantially the same point as existed prior to such amendment or
replacement.

         18.2 The Parties agree to use their respective best, diligent, and good
faith efforts to fulfill all of their obligations under this agreement. The
Parties recognize, however, that to effectuate all the purposes of this
agreement, it may be necessary either to enter into future agreements or to
amend this agreement, or both. In that event, the Parties agree to negotiate
with each other in good faith.

         18.3 This agreement constitutes the full and complete agreement of the
Parties with respect to the subject matter hereof. Any prior agreements among
the Parties with respect to this subject matter, are hereby superseded. This
agreement may not be amended, except by the written consent of the Parties.
Waiver of any breach of any provision of the agreement must be in writing signed
by the Party waiving such breach or provision and such waiver shall not be
deemed to be a waiver of any preceding or succeeding breach of the same or any
other provision. The failure of a Party to insist upon strict performance of any
provision of this agreement or any obligation under this agreement shall not be
a waiver of such Party's right to demand strict compliance therewith in the
future.

         18.4 The headings in this agreement are inserted for convenience and
identification only and are not intended to describe, interpret, define or limit
the scope, extent or intent of this agreement or any provision thereof.

         18.5 This agreement may be executed in counterparts, each of which
shall be deemed an original, but all of which together shall constitute one and
the same agreement.

         18.6 This agreement shall be construed in accordance with the internal
laws of the State of Delaware without reference to choice of law principles,
except as subject to the United States Arbitration Act and the Federal
Communications Act.

         18.7 Except for claims by third parties which fall within the scope of
a party's indemnification obligations under Section 6.3, neither party shall be
liable to the other party for any special, indirect, consequential, or punitive
damages.

         18.8 The parties agree that they will not use the name, service marks
or trademarks of the other party or any of its affiliates in any advertising,
publicity releases or sales presentations, without such party's written consent.
neither party is licensed hereunder to conduct business under any logo,
trademark, service or trade name (or any derivative thereof) of the other party.

         18.9 No party shall make any public statement or issue any press
release concerning the terms of this agreement except as necessary to comply
with requirements of any law, regulation, or the order or judgment of a court or
tribunal of competent jurisdiction. If any such public statement or release is
so required, and AWS and ACC mutually agree to such statement or release, the
party making such disclosure shall consult with the other party prior to making
such statement or release and the party shall use all reasonable efforts, act in
good faith, to agree upon a text for such statement or release which is
satisfactory to AWS and ACC. Nothing contained herein is intended to limit the
ability of the parties to make statements regarding the availability to such
party's customers of the services to be provided hereunder by the other party or
that such other party is the provider of such services.

         18.10 Neither of the parties will be liable for nonperformance or
defective performance of its obligations under this agreement to the extent and
for such periods of time as such nonperformance or defective performance is due
to reasons outside such party's control, including, without limitation, acts of
God, war, acts of any governmental authority, riots, revolutions, fire, floods,
explosions, sabotage, nuclear incidents, lightning, weather, earthquakes,
storms, sinkholes, epidemics, strikes, or delays of suppliers or subcontractors
for the same causes. Neither party shall be required to settle any labor dispute
or other third party dispute in any manner which is deemed by that party to be
less than totally advantageous, in that party's sole discretion.

         18.11 Except as specifically provided herein, this agreement is a
non-exclusive arrangement between the parties and nothing contained in this
agreement is intended or should be construed to preclude or limit a party from
obtaining from or providing to a third party service of a type available or
required to be provided under this agreement.
