PROVIDED, that if this Agreement is terminated by the Company pursuant to
5(b)(ii)(B), and AT&T designates the New Provider (as defined in Section
6(e)(i)), such New Provider may do, or cause or permit to be done, for or on
behalf of the Company, without the prior written consent of the Management
Committee, any of the actions set forth in clauses (i) through (xvi) above;
PROVIDED, FURTHER, that anything herein to the contrary notwithstanding, the New
Provider shall not take any action set forth on Exhibit B to the

                                       6
<PAGE>

LLC Agreement without obtaining approval of the Management Committee in the
manner specified in the LLC Agreement.  Prior to the effectiveness of any
assignment to a New Provider, such Person shall agree in writing to become
bound by this Agreement.

              (d)    BUDGETS.  Manager shall prepare or cause to be prepared and
present not later than 30 days before the beginning of each fiscal year
following the fiscal year 2000 an annual operating budget (with quarterly
forecasts) for the Company's review, evaluation and approval (each, as duly
approved by the Company, an "Operating Budget").  Each Operating Budget shall
set forth in reasonable detail the anticipated capital expenditures and other
projected costs and expenses of operating the Company's Cellular Systems during
the period covered by the budget, as well as projected revenues for that period
and the projected reportable income for such quarter and Manager shall endeavor
to assure the accuracy of its estimates.  Prior approval by the Company shall be
required for any expenditure which would result in operating expenditures
exceeding any summary line item in an Operating Budget by more than 10 percent
or the total amount of expenses contemplated by an Operating Budget by more than
10 percent.

              (e)    TRANSACTIONS WITH AFFILIATES.  Notwithstanding anything in
this Agreement to the contrary, without the prior approval of the Management
Committee, Manager shall not (and shall cause the Company and its Subsidiaries
not to) enter into any agreement, arrangement or understanding with Manager or
any of its Affiliates or any member of the Dobson Group except in the ordinary
course of the Business of the Company and on commercially reasonable terms that
are no less favorable to the Company or its Subsidiaries than the Company or its
Subsidiaries would obtain in a comparable arm's-length transaction with an
unaffiliated Person.  In its request for approval of the Management Committee,
Manager shall specify that the applicable transaction is subject to this Section
3(e).

       Section 4.    COMPENSATION.

              (a)    REIMBURSEMENT.  The Company shall reimburse Manager for all
out-of-pocket expenses ("Out-of-Pocket Expenses") reasonably incurred by Manager
for goods and services provided by third parties to, for or on behalf of the
Company or incurred by Manager in the performance of its duties and
responsibilities hereunder.  Manager shall provide the Company with a statement
setting forth in reasonable detail (and with copies of invoices or other
supporting documentation) the Out-of-Pocket Expenses claimed within thirty (30)
days after they are incurred, provided, that Out-of-Pocket Expenses incurred in
the last thirty (30) days of any fiscal year shall be claimed or estimated in
good faith at least two weeks prior to the end of such fiscal year.  The Company
shall pay to Manager each such amount within thirty (30) days of receipt of such
statement and invoices or other supporting documentation (it being understood
that estimated Out-of-Pocket Expenses will not be reimbursed until Manager
provides the Company with the invoices or other supporting documentation
therefor).

                                       7
<PAGE>

              (b)    COST ALLOCATIONS.  To the maximum extent practicable,
Manager and its Affiliates will specifically identify costs associated with the
Business, which shall be reimbursed by the Company as Out-of-Pocket Expenses in
accordance with Section 4(a).  To the extent that such specific identification
is impracticable, Manager shall charge the Company "Cost Allocations" for those
common costs which benefit the Company (including an appropriate portion of
Manager's general overhead expenses).  Cost Allocations (including without
limitation the cost of services directly allocable to the Company that are
performed by employees of DCC or its Affiliates) shall be calculated in the
manner set forth in Exhibit 4(b)(i).  Manager shall cause to be furnished to the
Company, at Company's expense, an accounting of any such Cost Allocations, and
the Company shall pay to Manager such amount within thirty (30) days of receipt
of such accounting. Exhibit 4(b)(ii) sets forth by category in reasonable detail
the per unit costs incurred by American Cellular Corporation in 1999, the per
unit costs incurred by Manager and its Affiliates in 1999, and Manager's good
faith estimate of the projected per unit costs to be incurred by the Company in
2000, in operating their respective Cellular Systems.

              (c)    DISPUTES, ETC.  If the Company disputes the amount of
Out-of-Pocket Expenses or Cost Allocations claimed by Manager, the Company
shall notify Manager in writing before payment is due, and if the matter
cannot be resolved informally between the parties, either the Company or
Manager may request resolution of the dispute pursuant to Section 10.

       Section 5.    TERM AND TERMINATION.

              (a)    TERM.  This Agreement shall commence on the Closing Date
under the Agreement and Plan of Merger dated as of October 5, 1999 among the
Company, ACC Acquisition Co. and American Cellular Corporation (the "Effective
Date") and shall terminate as provided herein or under the LLC Agreement.

              (b)    TERMINATION.

                     (i)    BY EITHER PARTY.  Either party may terminate this
       Agreement in the event that a Governmental Authority shall enter an order
       appointing a custodian, receiver, trustee, intervenor or other officer
       with similar powers with respect to the other party or with respect to
       any substantial part of its property, or constituting an order for relief
       or approving a petition in bankruptcy or insolvency law of any
       jurisdiction, or ordering the dissolution, winding up or liquidation of
       such party; or if a party files a petition seeking any such order; or if
       any such petition shall be filed against such party and shall not be
       dismissed within one hundred and twenty (120) days thereafter; or an
       order shall have been issued granting such party a suspension of payments
       under applicable law and any such order is not dismissed within one
       hundred and twenty (120) days thereafter.

                     (ii)   BY COMPANY.  The Company (acting through the
       Management Committee, excluding the Representatives appointed by DCC) may
       terminate this Agreement:

                            (A)    on five (5) days' notice in the event of a
              material breach of this Agreement by Manager (as determined by the
              Management Committee, excluding the Representatives appointed by
              DCC), which has not been cured within sixty (60) days following
              notice thereof from the Company;

                            (B)    on five (5) days' notice if (I) the DCC
              Affiliate Group ceases to be a Qualified Affiliate Group or (II) a
              Change of Control of DCC occurs and (x) a Prohibited Transferee
              (or, prior to the second anniversary of the Effective Date, any
              other Person) acquires control of Dobson and (y)(1) either the
              Company is a limited liability company and the AWS Affiliate Group
              is a Qualified Affiliate Group or (2) the Company has converted to
              a corporation and the AWS Affiliate Group retains at least 50% of
              its initial economic interests or (III) Manager ceases to be a
              wholly owned subsidiary of DCC;

                            (C)    on five (5) days' notice if the Company
              (acting through the Management Committee, excluding the
              Representatives appointed by DCC) has notified Manager of the
              Company's failure to comply with the Quality Standards in any
              material respect, and such failure has not been cured within sixty
              (60) days thereafter or, if such breach is not capable of being
              cured on commercially reasonable terms within such sixty (60) day
              period, within one-hundred eighty (180) days of such notice,
              provided that Manager is using reasonable best efforts to cure
              such breach as soon as reasonably practicable; and

                            (D)    on five (5) days' notice if the Company fails
              to comply with the financial performance standards set forth on
              Exhibit 3(c).

                     (iii)  BY MANAGER.  Manager may terminate this Agreement on
       five (5) days' notice in the event of a material breach of this Agreement
       by the Company (other than a payment default) which has not been cured
       within sixty (60) days following notice thereof from Manager.

              (c)    REMEDIES.  The remedies set forth herein are not intended
to be exclusive, and all remedies shall be cumulative and may be exercised
concurrently with any other remedy available to Manager or the Company at law or
in equity.

              (d)    CONTINUING OBLIGATIONS.  Notwithstanding the provisions of
Sections 6(a) and (b), no termination of this Agreement shall take effect until
the expiration of the Transition Period (as defined below).  After receipt of
written notice of termination, but prior to the expiration of the Transition
Period, Manager shall continue

                                       9
<PAGE>

to perform under this Agreement unless specifically instructed (by the
Management Committee, excluding the Representatives appointed by DCC) to
discontinue such performance in whole or in part.  In the event of
termination, Manager and the Company shall remain liable for their respective
obligations accrued under this Agreement prior to the expiration of the
Transition Period.

              (e)    TRANSITION ARRANGEMENTS.

                     (i)    GENERAL.  In the event of termination of this
       Agreement for any reason, Manager shall, during the Transition Period, at
       the Company's expense, cooperate with the Company in order to facilitate
       the transition to a new management service provider (the "New Provider")
       designated by AWS (which may be, at the election of AWS, an Affiliate of
       AWS).  Manager shall at the Company's expense take all commercially
       reasonable steps to assist the New Provider in assuming the management of
       the Company and the operation of the Company's Cellular  Systems
       including, without limitation, transferring to the New Provider all
       historical financial, tax, accounting, billing and other data with
       respect to the Company in the possession of Manager or its Affiliates,
       and giving such consents, assigning such permits and executing such
       instruments as may be necessary to vest in the New Provider those rights
       that were used by Manager to perform its services hereunder.
       Exhibit 5(e) sets forth those items of information and other assets and
       properties of the Company that Manager anticipates will be integrated in
       whole or in part with the operations of Manager or its Affiliates in the
       course of Manager's performance of its obligations hereunder, and that
       will accordingly need to be transferred to the Company or the New
       Provider in connection with any termination of this Agreement.

                     (ii)   USE OF MANAGER MARKS.  Notwithstanding anything
       herein to the contrary, in the event of termination of this Agreement by
       Manager other than pursuant to Section 5(b)(i) or Section 5(b)(iii),
       Manager shall use reasonable efforts to make available to the Company on
       commercially reasonable terms, by license, sublicense or otherwise,
       during the Transition Period, the right to market in those areas being
       served by the Company at the commencement of the Transition Period those
       products and services being marketed at the commencement of the
       Transition Period under those marks owned by or licensed to Manager or
       its Affiliates (the "Manager Marks") being used for such purpose at the
       commencement of the Transition Period (including the "Cellular One" name
       and logo and, if applicable, the "Dobson" name and logo) and, during the
       Transition Period and for six (6) months thereafter, neither Manager nor
       any of its Affiliates shall market under any of the Manager Marks in such
       areas such products and services.

                     (iii)  "Transition Period" means the period commencing on
       the effective date of termination of this Agreement and expiring on the
       later of (x) the first anniversary of such date of termination and (y)
       the date on which the

                                      10
<PAGE>

       Company, as managed by the New Provider, is able, in the good faith
       determination of AWS, to provide substantially the same level of service
       to its registered and roaming customers as it did when the Company was
       managed by Manager.

       Section 6.    NONCOMPETITION AND CONFIDENTIALITY.

              (a)    NONCOMPETITION.  During the Transition Period, neither
Manager nor any of its Affiliates shall assist or become associated with any
person or entity, whether as a principal, partner, employee, consultant or
shareholder (other than as a holder of not in excess of 5% of the outstanding
voting shares of any publicly traded company) that is actively engaged in the
business of providing Mobile Wireless Services in the Territory.

              (b)    CONFIDENTIALITY.  Manager shall, and shall cause each of
its Affiliates, and each of its and their respective partners, members,
managers, shareholders, directors, officers, employees and agents (collectively,
"Agents") to keep secret and retain in strictest confidence and not use for any
purpose any and all Confidential Information relating to the Company or any
member of the Company and shall not disclose such information, and shall cause
its Agents not to disclose such information, to the same extent provided in
Section 8.9 of the LLC Agreement.

              (c)    COMPANY PROPERTY.  Promptly following the termination of
this Agreement, Manager shall return to the Company all property of the Company,
and all copies thereof in its possession or under its control, and all tangible
embodiments of Confidential Information in its possession in whatever media such
Confidential Information is maintained.

              (d)    NON-SOLICITATION OF EMPLOYEES.  During the Transition
Period and for six months thereafter, neither Manager nor any of its Affiliates
will directly or indirectly induce any employee of the Company or any of its
Affiliates, or any employee of the New Provider or any of its Affiliates, to
terminate employment with such entity, and will not directly or indirectly,
either individually or as owner, agent, employee, consultant or otherwise,
employ or offer employment to any person who is or was employed by the Company
or any of its Affiliates, or by the New Provider or any of its Affiliates,
unless such person shall have ceased to be employed by such entity for a period
of at least six months.

              (e)    INJUNCTIVE RELIEF WITH RESPECT TO COVENANTS.  Manager
acknowledges and agrees that the covenants and obligations contained in this
Section 6 relate to special, unique and extraordinary matters and that a
violation of any of the terms of such covenants and obligations will cause the
Company irreparable injury for which adequate remedies are not available at law.
Therefore, Manager agrees that the Company shall be entitled to an injunction,
restraining order, or such other equitable relief as a court of competent
jurisdiction may deem necessary or appropriate to restrain Manager

                                      11
<PAGE>

and its Affiliates from committing any violation of the covenants and
obligations contained in this Section 6.  These injunctive remedies are
cumulative and are in addition to any other rights and remedies the Company
may have at law or in equity.

       Section 7.    FORCE MAJEURE.  Neither of the parties will be liable for
nonperformance or defective or late performance of any of its obligations
hereunder to the extent and for such periods of time as such nonperformance,
defective performance or late performance is due to reasons outside such party's
control, including acts of God, war (declared or undeclared), acts (including
failure to act) 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.

       Section 8.    BOOKS AND RECORDS.  Manager shall maintain and oversee the
maintenance and preparation of proper and complete records and books of account
for tax and financial purposes with respect to its management of the operation
of the Business, including all such transactions and other matters as are
usually entered into records and books of account maintained by Persons engaged
in business of like character or as required by law.  Manager shall maintain and
oversee the maintenance and preparation of complete records and books of the
Company for tax purposes.  Books and records maintained for financial purposes
shall be maintained in accordance with GAAP, and books and records maintained
for tax purposes shall be maintained in accordance with the Code and applicable
Treasury Regulations.  Within five (5) days after the end of each month Manager
shall prepare or cause to be prepared and transmit to the Company unaudited
statements, which shall include a general ledger and a trial balance.  Manager
shall also provide at the Company's request and expense any and all such
additional statements or reports as may be reasonably necessary to the Company's
oversight and control of the Business.  The Company shall have control over and
access, at all reasonable times during normal business hours, to the books and
records of the Company maintained by Manager pursuant to this Section 8.

       Section 9.    REGULATORY COMPLIANCE.  Subject to the other provisions of
this Agreement, Manager shall cause the Company and its Subsidiaries, and their
respective Cellular Systems, to remain in compliance in all material respects
with applicable laws, rules and regulations, including rules and regulations
promulgated by the FAA and the FCC.  Without limiting the generality of the
foregoing, the parties agree to comply with all applicable FCC rules and
regulations governing the Cellular Systems and the Licenses, and specifically
agree as follows:

              (a)    The Company (or its Subsidiaries which are the holders of
the Licenses) shall at all times maintain absolute control over, and retain the
ability to exercise the unfettered use of, the Licenses and the licensed
facilities provided thereunder, including the products and services to be
offered and the rates to be charged and the further right to terminate service
should public interest obligations under the applicable Licenses so require.

                                      12
<PAGE>

              (b)    Manager shall not represent itself as the holder of a
License to provide the Company Communications Services on any of the Cellular
Systems of the Company.

              (c)    Each customer (if any) billed by Manager shall be clearly
advised that service is provided over facilities licensed to the Company (or the
Subsidiary which is the holder of a License).

              (d)    Neither Manager nor the Company (or a Subsidiary which is a
holder of a License) shall represent itself as the legal representative of the
other before the FCC.  Manager and the Company (and each Subsidiary which is the
holder of a License) will cooperate with the other with respect to FCC matters
concerning the Cellular Systems.

              (e)    The Company (and each Subsidiary which is the holder of a
License) shall (i) in cooperation with Manager, take all actions necessary to
keep its Licenses in force and shall prepare and submit to the FCC, or any other
relevant authority, all reports, applications, renewals, filings or other
documents necessary to keep its Licenses in force and in good standing; (ii)
with all due assistance which may be necessary from Manager, respond promptly to
all FCC correspondence or inquiries and will immediately notify Manager of the
receipt thereof; and (iii) promptly report any changes of its address to the FCC
and to Manager.

              (f)    The Company (and each Subsidiary which is the holder of a
License) and Manager are familiar with the rules of the FCC regarding the
responsibility of the holder of a License under the Communications Act and
applicable FCC rules, regulations and policies.  Nothing in this Agreement is
intended to diminish or restrict the obligations of the Company (or a Subsidiary
which is the holder of a License) as an FCC licensee and both parties desire
that this Agreement be in compliance with the rules and regulations of the FCC.
If the FCC determines that any provision of this Agreement violates any FCC
rule, policy or regulation, all parties will make good faith efforts to
immediately correct the problem and bring this Agreement into compliance,
consistent with the intent of this Agreement.

       Section 10.   DISPUTE RESOLUTION.  If a dispute arises out of or relating
to this Agreement or the transactions contemplated hereby, or the construction,
interpretation, performance, breach, termination, enforceability or validity
hereof, whether such claim is based on rights, privileges or interests
recognized by or based upon contract, tort, fraud, misrepresentation, statute,
common law or any other legal or equitable theory, and whether such claim
existed prior to or arises on or after the Effective Date, the dispute
resolution processes set forth in Section 8.11 of the LLC Agreement shall govern
the resolution of such dispute.

       Section 11.   INSPECTION RIGHTS; DELIVERY OF INFORMATION.

              (a)    COMPANY'S RIGHT TO INSPECT.  Manager will permit
representatives of the Company or any Qualified Affiliate Group, at the
Company's or such Group's cost, during normal business hours and upon not less
than five business days' advanced written request, to (i) visit and inspect
during normal business hours Manager's properties and facilities which are
utilized in connection with Manager's provision of services to the Company
pursuant to this Agreement, including without limitation access to, and the
right to make copies of, books and records of the Company located at such
properties and facilities, and (ii) discuss with Manager's officers and

confidence by the Company or such Group, except for disclosures made to the
Company's or Group's advisors, lenders and investors, or as required to be
disclosed by process of law or other applicable law.

              (b)    NOTICE OF CERTAIN EVENTS.  Promptly, and in any event
within five (5) business days after Manager has received notice or has otherwise
become aware thereof, Manager shall give the Company notice of (i) the
commencement of any material proceeding or investigation against the Company or
Manager by or before any governmental body or in any court or before any
arbitrator which would be likely to have a material adverse effect on Manager,
the Business or the Company, or on Manager's ability to perform its obligations
hereunder, and (ii) the occurrence or non-occurrence of any event (x) which
constitutes, or which with the passage of time or giving of notice or both would
constitute, a default by the Company or Manager under this Agreement or under
any other material agreement to which the Company or Manager is a party or by
which its properties may be bound, and (y) would be likely to have a material
adverse effect on Manager, the Business or the Company, or on Manager's ability
to perform its obligations hereunder, giving in each case the details thereof
and specifying the action being taken or proposed to be taken with respect
thereto.  Promptly upon receipt thereof, Manager shall deliver to the Company
copies of any material notice or report regarding any License from the grantor

Company.

or results of operations of Manager, as may be reasonably requested by the
Company.

and permitted assigns; PROVIDED, however, that Manager shall not assign or

Committee excluding the Representatives appointed by DCC).  The parties agree
