         foregoing provisions and the other provisions of this Agreement

         with Treasury Regulation Section 1.704-1(b), and shall be interpreted
         and applied in a manner consistent with such regulation. To the extent
         the provisions of this Agreement are inconsistent with such regulation
         or are incomplete with respect thereto, the Capital Accounts of the
         Members shall be maintained in accordance with such regulation except
         to the extent that doing so would materially distort the timing or
         amount of an allocation or distribution to a Member.

                  3.2   CAPITAL CONTRIBUTIONS.

                  (a)   On the Effective Date, each of AWS Sub and DCC Sub

                  3.4   NO INTEREST. Except as expressly set forth herein, no

                                    ARTICLE 4
                               PROFITS AND LOSSES

                  4.1   PROFITS. Except as provided in Sections 4.2 through
4.5, Profits and Losses with respect to any fiscal year shall be allocated to
the Members in accordance with their respective Economic Interests.

                  4.2   LOSSES.

                  (a)   GENERAL RULE. After giving effect to the special
allocations set forth in Section 4.3 and 4.4, subject to Section 4.2.(b), Losses
with respect to any fiscal year shall be allocated to the Members in accordance
with their respective Economic Interests.

                  (b)   LIMITATION ON LOSSES. Losses allocated to any Member
pursuant to Section 4.1 with respect to any fiscal year shall not exceed the
maximum amount of Losses that may be so allocated without causing such Member to
have an Adjusted Capital Account Deficit at the end of such fiscal year. All
Losses in excess of the limitation set forth in this Section 4.2 shall be
allocated: first, to the Members that will not be subject to this limitation,
ratably based on the aggregate of their Economic Interests, to the extent
possible until such Members become subject to this limitation; and any remaining
amount, to the Members, ratably based on their Economic Interests, unless
otherwise required by the Code or Treasury Regulations. To the extent that any
Member receives an allocation of Losses pursuant to this Section 4.2, such
Member shall receive a priority allocation of Profits (prior to an allocation of
Profit made pursuant to Section 4.1) in the reverse order of such Loss
allocations in order to reverse the effect of this Section 4.2.

                  4.3   SPECIAL ALLOCATIONS. The following special
allocations shall be made for any fiscal year of the Company in the following
order of priority:

                  (a)   QUALIFIED INCOME OFFSET. Notwithstanding anything
herein to the contrary, but only if required by Treasury Regulation Section
1.704-1(b) in order for the allocations provided for herein to be considered
to have substantial economic effect or to be deemed to be in accordance with
the Member's Economic Interests, if, for any fiscal year, a Member
unexpectedly receives an adjustment, allocation or distribution described in
Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6), and such
adjustment, allocation or distribution causes or increases an Adjusted
Capital Account Deficit with respect to such Member, then, before any other
allocations are made, such Member shall be allocated items of income and gain
(consisting of a pro rata portion of each item of Company income, including
gross income and gain) in the amount and manner sufficient to eliminate such
Adjusted Capital Account Deficit as quickly as possible. This Section 4.3(a)
is intended

                                       21

<PAGE>

to comply with Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be
interpreted consistently therewith.

                  (b)   MINIMUM GAIN CHARGEBACK. Notwithstanding any other
provision of this Article 3, if there is a net decrease in Company Minimum Gain
during any fiscal year, each Member shall, subject to the exceptions provided in
Treasury Regulation Section 1.704-2(f), be specially allocated items of income
and gain for such fiscal year (and, if necessary, subsequent fiscal years) equal
to such Member's share of the net decrease in Company Minimum Gain within the
meaning of Treasury Regulation Section 1.704-2(g)(2). Allocations pursuant to
the previous sentence shall be made in proportion to the respective amounts
required to be allocated to each Member pursuant thereto. The items to be so
allocated shall be determined in accordance with Treasury Regulation Sections
1.704-2(6) and 1.704-2(i)(2). To the extent that this Section 4.3(b) is
inconsistent with Treasury Regulation Section 1.704-2(f), the Minimum Gain
Chargeback provided for herein shall be applied and interpreted in accordance
with such Treasury Regulation.

                  (c)   MEMBER MINIMUM GAIN CHARGEBACK. If there is a net
decrease in Member Minimum Gain attributable to a Member Nonrecourse Debt
during any Company fiscal year, within the meaning of Treasury Regulation
Sections 1.704-2(i)(3) and 1.704-2(k), each Member that, as of the beginning
of such year, has a share of the Member Minimum Gain attributable to such
Member Nonrecourse Debt, determined in accordance with Treasury Regulation
Section 1.704-2(i)(5), shall be specially allocated items of income and gain
for such fiscal year (and, if necessary, subsequent fiscal years) in an
amount equal to such Member's share of the net decrease in Member Nonrecourse
Debt determined in accordance with Treasury Regulation Section 1.704-2(i)(4).
Allocations pursuant to the previous sentence shall be made in proportion to
the respective amounts required to be allocated to each Member pursuant
thereto. The items to be so allocated shall be determined in accordance with
Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(i)(2). To the extent
that this Section 4.3(c) is inconsistent with Treasury Regulation Section
1.704-2(i), the Member Minimum Gain chargeback provided for herein shall be
applied and interpreted in accordance with such regulation.

                  (d)   NONRECOURSE DEDUCTIONS. Nonrecourse Deductions shall
be allocated to the Members in accordance with their respective Economic
Interests.

                  (e)   MEMBER NONRECOURSE DEDUCTIONS. Any Member Nonrecourse
Deductions for any fiscal year or other period shall be allocated to the
Member that bears the economic risk of loss with respect to the Member
Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable
in accordance with Treasury Regulation Section 1.704-2(i).

                  4.4   CURATIVE ALLOCATIONS. The allocations set forth in
Sections 4.3(a) through 4.3(e) are intended to comply with certain regulatory
requirements under Section 704(b) of the Code. The Members intend that, to the
extent possible, all allocations made pursuant to such Sections will, over the
term of the Company, be offset either with

                                       22

<PAGE>

other allocations pursuant to Section 4.3 or with special allocations of
other items of Company income, gain, loss, or deduction pursuant to this
Section 4.4. Accordingly, the Management Committee is hereby authorized and
directed to make offsetting allocations of Company income, gain, loss or
deduction under this Section 4.4 in whatever manner the Management Committee
determines is appropriate so that after such offsetting special allocations
are made (and taking into account the reasonably anticipated future
allocations of income and gain pursuant to Section 4.3(b) and Section 4.3(c))
the Capital Accounts of the Members are, to the extent possible, equal to the
Capital Accounts each would have if the provisions of Section 4.3 were not
contained in this Agreement and all income, gain, loss and deduction of the
Company were instead allocated pursuant to Section 4.1 and Section 4.2.

                  4.5   SPECIAL ALLOCATIONS IN THE EVENT OF COMPANY AUDIT
ADJUSTMENTS. Notwithstanding the allocation provisions of Section 4.1 and
Section 4.2, and prior to making any of the allocations specified in Section
4.3, the following special allocations shall be made in the following order
and in a manner, taking into consideration any tiered partnership structure
that the Company may be part of, that reflects the relative economic
interests of each Member in the Company:

                  (a)   If for any fiscal year of the Company, the Company or
any Affiliate of the Company is deemed to have additional income for tax
purposes as a result of a redetermination by a taxing authority of an item of
income, gain, loss or deduction that is attributable to a loan transaction,
the provision of services, or the grant of a license or sublicense in
intangible property by the Company or any Affiliate of the Company, to or
involving any Member or Affiliate of any Member, such additional income shall
be allocated to the Member involved in such loan transaction or that received
such services, license or sublicense (or the Member whose Affiliate was
involved in such loan transaction or received such services, license or
sublicense) and any related deemed cash distribution shall be treated as
having been made to the same Member.

                  (b)   If for any fiscal year of the Company, the Company or
any Affiliate of the Company is deemed to have a reduction in income for tax
purposes as a result of a redetermination by a taxing authority of an item of
income, gain, loss or deduction that is attributable to a loan transaction,
the provision of services, or the grant of a license or sublicense in
intangible property by the Company or any Affiliate of the Company, to or
involving any Member or Affiliate of any Member, such reduction in income
shall be allocated to the Member involved in such loan transaction or that
received such services, license or sublicense (or the Member whose Affiliate
was involved in such loan transaction or received such services, license or
sublicense) and any related deemed cash contribution shall be treated as
having been made by the same Member.

                  (c)   If for any taxable period of a Member, such Member or
any Affiliate of the Member is deemed to have additional income for tax
purposes as a result of a redetermination by a taxing authority of an item of
income, gain, loss or deduction attributable to a loan transaction, the
provision of services, or the grant of a license or sublicense in intangible
property by such Member or any Affiliate of such Member, to or

                                       23

<PAGE>

involving the Company or any Affiliate of the Company, any increase in the
amount of a Company deduction associated with such redetermination of such
Member's or any Affiliate of such Member's income shall be allocated (in the
appropriate fiscal year) to the Member involved in such loan transaction or
that provided such services, license or sublicense (either directly or
through an Affiliate), and any related deemed cash contribution shall be
treated as having been made by the same Member.

                  (d)   If for any taxable period of a Member, such Member or
any Affiliate of the Member is deemed to have a reduction in income for tax
purposes as a result of a redetermination by a taxing authority of an item of
income, gain, loss or deduction attributable to a loan transaction, the
provision of services, or the grant of a license or sublicense in intangible
property by such Member or any Affiliate of such Member, to or involving the
Company or any Affiliate of the Company, any reduction in the amount of a
Company deduction associated with such redetermination of such Member's or
any Affiliate of such Member's income shall be allocated (in the appropriate
fiscal year) to the Member involved in such loan transaction or that provided
such services, license or sublicense (either directly or through an
Affiliate), and any related deemed cash distribution shall be treated as
having been made to the same Member.

                  (e)   A redetermination by a taxing authority shall only be
given effect for purposes of this Section 4.5 if such redetermination is (i)
a decision, judgment, decree or other order by any court of competent
jurisdiction, which has become final and is either no longer subject to
appeal or for which a determination not to appeal has been made; (ii) a
closing agreement made under Section 7121 of the Code or any comparable
foreign, state, local or other income tax statute; (iii) a final disposition
by a taxing authority of a claim for refund; or (iv) any other written
agreement made with respect to a tax redetermination the execution of which
is final and prohibits the taxing authority, relevant Member (or any
Affiliate of such Members) or the Company (or any Affiliate of the Company)
from seeking any further legal or administrative remedies with respect to
such tax redetermination.

                  4.6   ALLOCATION OF CREDITS. All tax credits shall be
allocated among the Members in accordance with their respective Interests or
in accordance with applicable provisions of the Code or Treasury Regulations
to the extent any such provision is inconsistent with such allocation.

                  4.7   TAX ALLOCATIONS.

                  (a)   CONTRIBUTED PROPERTY. In the event any property is
contributed to the capital of the Company, income, gain, loss and deduction with
respect to such property shall be allocated solely for tax purposes among the
Members in accordance with Section 704(c) of the Code and Treasury Regulation
Section 1.704-3 so as to take account of any variation between the adjusted
basis of such property to the Company for federal income tax purposes and its
initial Book Value. Prior to the contribution of any property to the Company
that has a Fair Market Value that differs from its adjusted tax basis in the
hands of the contributing Member on the date of contribution, the contributing
Member and the Management

                                       24

<PAGE>

Committee shall agree upon the allocation method to be applied with respect
to that property under Treasury Regulation Section 1.704-3, which allocation
method shall be set forth on attached Schedule 4.7, as amended from time to
time.

                  (b)   REVALUED PROPERTY. If the Company assets are revalued
as set forth in the definition of "Book Value," subsequent allocations of
income, gain, loss and deduction with respect to revalued Company assets
shall take into account any variation between the adjusted basis of such
assets for federal income tax purposes and their adjusted value in the same
manner as under Section 704(c) of the Code and in compliance with Treasury
Regulation Section 1.704-3. All decisions regarding the choice of allocation
method under Treasury Regulation Section 1.704-3 with respect to revalued
Company assets shall be made by the Management Committee.

                  4.8   CHANGE IN MEMBER'S INTERESTS. In the event there is any
change in the Members' respective Economic Interests during any fiscal year,
Profits, Losses, Nonrecourse Deductions and other items shall be allocated among
the Members in accordance with their respective Economic Interests from time to
time during such fiscal year in accordance with Section 706 of the Code, using
any convention permitted by law and selected by the Management Committee.

independent public accountants, such designation and appointment to remain

                                 Regulations);

                                 consistent with those assumed in connection
                                 with entering into this Agreement; and

                        (D)      Have the Company treated as a partnership
                                 for federal income tax purposes in a manner

         assets under Section 734(b) or 743(b) of the Code and a corresponding

                                       27

<PAGE>

                  (i)   The Tax Matters Partner will prepare or cause to be
         prepared all required domestic and foreign tax returns and information
         returns of the Company, drafts of which shall be furnished to the
         Members within 120 days following the close of each fiscal year. Such
         returns will be prepared at no charge to the Company, except for all
         reasonable out-of-pocket expenses (including accounting fees, if any).
         Either Member may, at its own expense, engage a third party to review
         the tax returns and information returns prepared by the Tax Matters
         Partner pursuant to the preceding sentence. The Tax Matters Partner
         shall not file any such return without the approval of any Member that
         constitutes a "notice partner" (as defined in Section 6231(a)(8) of the
         Code) of the Company, which approval shall not be unreasonably
         withheld. Such "notice partner" member shall be deemed to have given
         such approval if such Member does not indicate its written objection
         (which may be delivered by facsimile) to the Tax Matters Partner within
         45 days of the date that such Member receives a draft of such return.
         If a "notice partner" Member does not approve of any proposed filing of
         a return by the Tax Matters Partner, such Member and the Tax Matters
         Member shall seek, in good faith, to resolve their disagreement. If a
         "notice partner" Member and the Tax Matters Partner cannot resolve
         their disagreement within 10 days of receipt of such written notice by
         the Tax Matters Partner, either of such Member or the Tax Matters
         Partner may request, in writing with a copy sent to the other party,
         that the disagreement be resolved by the Company's independent public
         accountants and the independent public accountants shall be instructed
         to resolve the dispute in such manner as they believe will maximize, in
         the aggregate, the U.S. federal, state and local income tax advantages
         and will minimize, in the aggregate, the U.S. federal, state, and local
         income tax detriments, available to the Company's Members. The
         independent public accountants shall provide their written resolution
         of the disagreement to both the "notice partner" Member and the Tax
         Matters Partner within 15 days from the date that the independent
         public accountants were requested to resolve such disagreement. Any and
         all other tax returns shall be prepared in a manner directed by the Tax
         Matters Partner consistent with the terms of this Agreement. Each
         Member shall provide such information, if any, as may be reasonably
         requested by the Company for purposes of preparing such tax and
         information returns.

                  (ii)  The Tax Matters Partner shall furnish a copy of all
         filed domestic foreign tax returns and information returns for the
         Company to each of the Members. In addition, upon reasonable written
         notice provided to the Company by a Member (and as otherwise required
         by law), the Company shall furnish such Member, on a timely basis, with
         all information relating to the Company required to be reported in any
         U.S. federal, state or local tax return of such Member, including a
         report indicating such Member's allocable share for U.S. federal income
         tax purposes of the Company's income, gain, credits, losses and
         deductions.

                  (iii) The Members agree that the Company shall be treated as a
         partnership for U.S. federal income tax purposes. The Members agree to
         (A) approve electing

                                       28

<PAGE>

         partnership status with respect to the Company with the U.S. Internal
         Revenue Service and such other state and local taxing authorities as
         may be appropriate and to cooperate in providing all consents,
         signatures, documents and such other information as may be required
         with respect thereto; and (B) report all "partnership items" (as
         defined in Section 6231(a)(3) of the Code) of the Company consistent
         with such classification of the Company for U.S. federal, state and
         local tax purposes and with the returns filed by the Company; provided,
         however, that if any Member intends to file a notice of inconsistent
         treatment under Section 6222(b) of the Code, such Member shall at least
         30 days prior to the filing of such notice, notify in writing the other
         Members of such intent and such Member's intended treatment of the item
         which is (or may be) inconsistent with the treatment of that item by
         the Company.

                  (d)   TAX AUDITS. DCC Sub, so long as it is a Qualified
Member (or, from and after a Change of Control of DCC, AWS Sub, so long as it
is a Qualified Member) shall be the "tax matters partner" of the Company, as
that term is defined in Section 6231(a)(7) of the Code (the "Tax Matters
Partner"), with all of the rights, duties and powers provided for in sections
6221 through 6232, inclusive, of the Code, provided that the Tax Matters
Partner shall not pay or agree to pay any audit assessment, or any amount in
settlement or compromise of any litigation, in respect of income tax
liability of the Members attributable to the Interests in the Company, in
excess of $500,000 in any one instance or series of related instances, unless
approved by the Management Committee. The Tax Matters Partner, as an
authorized representative of the Company, shall direct the defense of any tax
claims made by the Internal Revenue Service or any other taxing jurisdiction
to the extent that such claims relate to adjustment of Company items at the
Company level and, in connection therewith, shall retain and cause the
Company to pay the fees and expenses of counsel and other advisors chosen by
the Tax Matters Partner. The Tax Matters Partner shall also be responsible
for filing a timely election on Form 8832 and for timely filing for all other
elections made by the Company. The Tax Matters Partner shall deliver to each
Member and the Management Committee a semi-annual report on the status of all
tax audits and open tax years relating to the Company, and shall consult with
and keep all Members and the Management Committee advised of all significant
developments in such matters coming to the attention of the Tax Matters
Partner. All reasonable expenses of the Tax Matters Partner and its
Affiliates (including reasonable internal time charges and reasonable
disbursements) and other reasonable fees and expenses in connection with such
defense shall be borne by the Company. Except as provided in Article 11,
neither the Tax Matters Partner nor the Company shall be liable for any
additional tax, interest or penalties payable by a Member or any costs of
separate counsel chosen by such Member to represent the Member with respect
to any aspect of such defense. The Tax Matters Partner shall take any steps
necessary pursuant to Section 6223(a) to designate AWS Sub as a "notice
partner" (as defined in Section 6231(a)(8) of the Code). In addition, nothing
in this Agreement is intended to waive any rights, including rights to
participate in administrative and judicial proceedings, that a Member may
have under Section 6221 through 6233 of the Code. Notwithstanding any other
provisions of this Agreement, the provisions of Sections 6.5(c) and 6.5(d)
shall survive the dissolution of the Company or the termination of any
Member's interest in the Company and shall remain binding on all Members for
a period of time necessary to resolve with the U.S.

                                       29

Internal Revenue Service or any applicable state or local taxing authority
all matters (including litigation) regarding the U.S. Federal, state and
local income taxation, as the case may be, of the Company or any Member with
respect to the Company.

                  (e)   WITHHOLDING.

                  (i)   The Company shall comply with all withholding
         requirements under U.S. federal, state, local and foreign tax laws
         and shall remit amounts withheld to, and file required forms with,
         the applicable taxing authorities. To the extent that the Company
         withholds and pays over any amounts to any taxing authority with
         respect to distributions or allocations to any Member, the amount
         withheld shall be charged to the Capital Account of such Member. The
         Company shall notify each of the Members of any withholding with
         respect to such Member, designating such Member's allocable share of
         such withholding tax. The Members hereby agree that they will not
         claim a credit in excess of the amount in such notice.

                  (ii)  In the event of any claimed overwithholding by the
         Company, the Member shall have no rights against the Company or any
         other Member. Anything in the previous sentence to the contrary
         notwithstanding, if the Company is required to take any action in order
         to secure a refund or credit for the benefit of a Member in respect of
         any amount withheld by it, it will take any such action including,
         without limitation, applying for such refund on behalf of the Member
         and paying it over to such Member.

                  (iii) Except in the case of withholding pursuant to Section
         1446 of the Code, if any amount required to be withheld was not
         withheld from actual distributions made to a Member, the Company shall
         require the Member to which the withholding was credited to reimburse
         the Company for such withholding; in the case of withholding pursuant
         to Section 1446 of the Code, no such reimbursement will be necessary as
         long as the other Members are subject to withholding in amounts
         proportionate to their Economic Interests in the Company or otherwise
         receive a distribution of an equivalent amount.

                  (iv)  In the event of any underwithholding by the Company,
         each Member agrees to indemnify and hold harmless the Company and
         the Tax Matters Member from and against any liability, including
         interest and penalties, with respect thereto.

                  (v)   Each Member agrees to furnish the Company with any
         representations and forms as shall reasonably be requested by the
         Company to assist the Company in determining the extent of, and in
         fulfilling, the Company's withholding obligations.

                  7.1   MANAGEMENT COMMITTEE. The property, business and affairs
of the Company shall be managed by or under the direction of a Management
Committee (the "Management Committee"). In addition to the powers and
authorities by this Agreement expressly conferred upon it, the Management
Committee may exercise all such powers of the Company and do all such lawful
acts and things as are not by statute or by this Agreement directed or required
to be exercised or done by the Members. Except as determined by the Management
Committee pursuant to this Article 7 or otherwise pursuant to this Agreement, no
Member or Representative shall have any right or authority to take any action on
behalf of the Company with respect to third parties or to bind the Company.

                  (a)   NUMBER OF REPRESENTATIVES. The Management Committee
shall consist of four individuals (each, a "Representative"). So long as the
AWS Member Group is a Qualified Member Group, except as otherwise provided in
Section 8.12, AWS Sub (or another Member designated by a majority in Voting
Interests of the AWS Member Group) shall have the right to appoint two
Representatives, each of whom shall be employees of AWS or its Affiliates. So
long as the DCC Member Group is a Qualified Member Group, except as otherwise
provided in Section 9.8(a)(ii), DCC Sub (or another Member designated by a
majority in Voting Interests of the DCC Member Group) shall have the right to
appoint two Representatives, each of whom shall be employees of DCC or its
Affiliates. If a Member Group loses the right to appoint two Representatives,
the size of the Management Committee shall be reduced to two members, who
shall be appointed by the other Member Group. The Representatives shall not
be "managers" of the Company as such term is used in the Act.

                  (b)   INITIAL REPRESENTATIVES.  The initial Representatives
are:

                           DCC Member Group:         Everett R. Dobson
                                                     Bruce R. Knooihuizen

                           AWS Member Group:         Don Adams
                                                     Lee Maschmann

                  (c)   VACANCIES. Each Representative shall hold office until
death, resignation or removal, with or without cause, by the Member Group which
appointed such Representative. If a vacancy occurs on the Management Committee,
the Member Group that appointed the vacating Representative shall (so long as
such Member Group has not lost the right to appoint two Representatives pursuant
to Section 7.1(a)) appoint such Representative's successor.

                  (a)   REGULAR MEETINGS. The Management Committee shall meet at
least four times per year. Such meetings shall be held on such dates and at such
times and places as may be determined by the Representatives.

                  (b)   SPECIAL MEETINGS. A special meeting of the Management
Committee or the Members shall be held at the request of any Representative.
Such meeting shall be held on the date and at the time and place set forth in
the notice of meeting.

                  (c)   TELEPHONIC MEETINGS. Any meeting of the Management
Committee or the Members may be held by conference telephone call or through
similar communications equipment by means of which all persons participating in
the meeting can hear and be heard by each other. Participation in such a
telephonic meeting shall constitute presence in person at such meeting.

                  (d)   NOTICES. Notices of regular meetings and special
meetings of the Management Committee or the Members may be given by any
Representative, and shall state the date, hour and purpose of the meeting.
All such notices shall be accompanied by an agenda for the meetings, as well
as (to the extent practicable) the texts of all resolutions proposed to be
adopted at such meetings. No item may be discussed if not on the agenda
unless a quorum is present and the Representatives present waive notice of
the additional item(s). Notice of a regular or special meeting shall be given
by facsimile, confirmed by certified mail, return receipt requested not less
than 14 days (in the case of a regular meeting) or 72 hours (in the case of a
special meeting) before the date of the meeting to each Representative at the
facsimile number and address provided by the Representative to the Company
from time to time. Any Representative may waive, as to such Representative
only, in writing, the requirements for notice before, at or after a meeting.
Any Representative who attends a meeting without objecting at the meeting to
the Company's failure to comply with the notice requirements in respect of
such meeting shall be deemed to have waived such requirements.

                  (e)   QUORUM. At each meeting of the Management Committee
or the Members, the presence in person or by telephone of at least one
Representative of each Member Group shall be necessary to constitute a quorum
for the transaction of business.

                  (f)   WRITTEN CONSENTS. Any action required or permitted to
be taken at a meeting of the Management Committee or the Members may be taken
without a meeting, but upon the requisite notice as provided in paragraph (d)
above, if the requisite Representatives of each Member Group consent thereto in
writing, and if a complete and correct copy of such consent is promptly
delivered to all the Representatives of each Member Group following the
execution of any such consent.

                  7.3   ACTIONS BY MANAGEMENT COMMITTEE.

                  (a)   SCOPE OF AUTHORITY. The Management Committee shall have
full power and authority to direct and control the business and affairs of the
Company except as otherwise required by applicable law, and subject to the right
of the Management Committee to delegate such power and authority to Persons
responsible for day-to-day operation of the Company (it being understood that
authority to undertake Significant Matters prior to approval by the Management
Committee shall not be so delegated).

                  (b)   ACTIONS REQUIRING MANAGEMENT COMMITTEE APPROVAL. Without
limiting the generality of the foregoing, the following actions shall require
approval of the Management Committee:

                  (i)   approving any Significant Matter;

                  (ii)  approving or taking any action for which the approval or
         action of the Company is required under the Related Agreements, except
         as the Management Committee may otherwise delegate in accordance with
         paragraph (a) above; and

                  (iii) approving any other matter that the Management Committee
         determines shall require its approval as such items may be set forth on
         Schedule 7.3(b) from time to time.

                  (c)   APPROVAL REQUIREMENTS.

                  (i)   Except as otherwise specifically provided herein,
         consent or approval of the Management Committee shall mean the
         affirmative vote of a majority of the Representatives voting at a
         duly held meeting of the Management Committee; provided, that with
         respect to any Significant Matter, consent or approval of the
         Management Committee shall mean the affirmative vote of all existing
         Representatives; provided, however, that the Management Agreement may
         be terminated, and the Manager removed and replaced, only in accordance
         with the terms thereof.

                  (ii)  Each Representative shall be entitled to one vote on all
         matters submitted to a vote of the Management Committee; provided, that
         if one or more Representatives are absent or not appointed because of a
         vacancy on the Management Committee or otherwise, then any other
         Representative of such absent Representative's Member Group present at
         the meeting shall have the right to cast the votes of such absent
         Representative(s).

                  (iii) The Company shall provide each Representative with (A)
         adequate notice (in light of the time frame in which approval is
         sought) of the substance of any matter requiring the approval of the
         Management Committee in order to afford such Representative sufficient
         time to review such matter and the Company's analysis thereof and (B)
         an opportunity to consult with the management of the Company

                                      33
<PAGE>

         regarding such matter and possible alternatives prior to the meeting
         at which approval is sought; provided, that any alleged noncompliance
         with the provisions of this paragraph (iii) shall not affect the
         validity of any consent or approval pursuant to paragraphs (i) and
         (ii) above.

                  (d)   INITIAL BUDGET. The budget for the Company's first three
years of operations shall be approved by the Management Committee simultaneously
with the execution of this Agreement or promptly thereafter.

                  (e)   ANNUAL BUDGETS. The Management Committee shall adopt an
annual budget for the operations of the Company, which budget shall be in at
least as much detail and cover the same matters as the initial budget. The
proposed budget shall be presented to the Management Committee no later than 60
days prior to the commencement of the fiscal year of the Company to which it
pertains. Any annual budget adopted by the Management Committee that covers any
period covered by the initial three-year budget shall replace the initial
three-year budget with respect to such period.

                    OPERATING AGREEMENTS AND OTHER COVENANTS

                  8.1   LIMITED EXCLUSIVITY.

                  (a)   Except as provided in connection with a Disqualifying
Transaction, so long as the Company continues to meet the TDMA Quality Standards
in all material respects in all of its markets, AT&T 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, in each case within five years after the Effective Date, except that
AT&T and its Affiliates may:

                  (i)   resell, or act as the Company's agent for, Company
         Communications Services provided by the Company in accordance with a
         Resale Agreement (or any other agreement between AWS Sub and its
         Affiliates, on the one hand, and the Company, on the other hand), and
         provide Company Communications Services to its own customers under the
         Operating Agreement (including AWS Sub and its Affiliates providing
         local numbers in the Territory or otherwise providing numbers and
         service to residents of the Territory), including bundling any such
         Company Communications Services with other Telecommunications Services
         marketed, offered and provided or resold by AWS Sub or any of its
         Affiliates;

                  (ii)  provide or resell wireless Telecommunications Services
         to or from specific locations (such as buildings or office
         complexes), even if the subscriber equipment used in connection with
         such service may be capable of routine movement within a limited
         area (such as a building or office complex), and even if such
         subscriber equipment may be capable of obtaining other
         Telecommunications

                                      34
<PAGE>

         Services beyond such limited area (which other services may include
         routine movement beyond such limited area) and hand-off between the
         service to such specific locations and such other Telecommunications
         Services; provided, however, that if AT&T or any of its Affiliates
         sells such Mobile Wireless Services subscriber equipment as part of
         such offering such equipment shall be capable of use in obtaining
         (but not necessarily on an exclusive basis) Company Communications
         Services;

                  (iii) 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;

                  (iv)  acquire a controlling interest in Tritel, Inc. or its
         successors or assigns; provided, that at the time of such acquisition
         Tritel, Inc. (or its successors or assigns) do not hold Licenses issued
         by the FCC covering service areas within the Territory other than
         Licenses in the service areas covered by the Licenses held by Tritel,
         Inc. on the Effective Date that are listed on Schedule 8.1(a)(iv); and
         provided, further, that AT&T and its Affiliates will continue to be
         obligated to comply with their obligations under Section 8.2; and

                  (v)   take such action as may be necessary or advisable to
         comply only to the extent required with the construction requirements
         of 47 CFR 24.203 in respect of the PCS licenses listed on Schedule
         8.1(a)(v), and the Company shall cooperate with AT&T and its
         Affiliates, at their request and expense, in connection therewith.

                  (b)   To the extent the "other Telecommunications Services"
referred to in Section 8.1(a)(ii) are classified as Mobile Wireless Services,
neither AT&T nor any of its Affiliates or any AT&T licensee may provide or
resell, or act as agent for any Person offering, such Mobile Wireless Services
except Mobile Wireless Services provided by the Company in accordance with the
terms of Section 8.1(a)(i) or pursuant to roaming arrangements which comply with
Section 8.2. Nothing herein shall be construed to limit in any respect any
advertising and promotional and similar activities by AT&T or its Affiliates.

                  (c)   The agreements set forth in this Section 8.1 will
terminate five years after the Effective Date, unless the parties agree to
extend such arrangements on mutually acceptable terms.

                  8.2   ROAMING PREFERENCE.

                  (a)   For five years following the Effective Date, with
respect to the markets operated in the Territory, each of the Company and
(except as provided in connection with a Disqualifying Transaction) AT&T
shall, and shall cause each of its Affiliates to, in its and such Affiliates'
capacity as Home Carrier: (i) program and direct its authorized dealers to
program the subscriber equipment provided by it or such authorized dealers to
its customers, at the time it is provided to such customers (to the extent
such programming is

                                      35
<PAGE>

technologically feasible) so that the Company or AT&T, as the case may be, and
such Affiliates, in its and such Affiliates' capacity as Serving Carrier, is the
preferred provider of roaming service in such markets, and (ii) refrain, and
direct its authorized dealers to refrain, from inducing any of its customers to
change or, except at such customer's request in the event the quality of the
Company's services do not meet the TDMA Quality Standards, from changing the
programming described in clause (i) above.

                  (b)   For five years following the Effective Date, with
respect to the markets operated in the Territory, each of the Company and DCC
shall, and shall cause each of its Affiliates (other than Logix
Communications) to, in its and such Affiliates' capacity as Home Carrier: (i)
program and direct its authorized dealers to program the subscriber equipment
provided by it or such authorized dealers to its customers, at the time it is
provided to such customers (to the extent such programming is technologically
feasible) so that the Company or DCC, as the case may be, and such
Affiliates, in its and such Affiliates' capacity as Serving Carrier, is the
preferred provider of roaming service in such markets, and (ii) refrain, and
direct its authorized dealers to refrain, from inducing any of its customers
to change or, except at such customer's request in the event the quality of
the Company's services do not meet the TDMA Quality Standards, from changing
the programming described in clause (i) above.

                  (c)   As used in this Section 8.2, the terms "Affiliate,"
"Home Carrier" and "Serving Carrier" shall have the meanings ascribed thereto
in the Operating Agreement.

                  (d)   The agreements set forth in this Section 8.2 will
terminate five years after the Effective Date, unless the parties agree to
extend such arrangements on mutually acceptable terms.

                  8.3   RESALE AND AGENCY AGREEMENTS.

                  (a)   From time to time, upon the request of AWS Sub, the
Company shall enter into a Resale Agreement relating to the Territory with AWS
Sub and any of its Affiliates and, with respect to any geographic area within
the Territory, one other Person designated by AWS Sub, provided such other
Person is licensed to provide Telecommunications Services in such geographic
area under the service marks used by AWS and qualifies as a reseller under any
generally applicable standards the Company establishes for its resellers from
time to time, and upon the request of AWS, the Company shall enter into an
agency agreement authorizing AWS Sub and any of its Affiliates and, with respect
to any geographic area within the Territory, one other Person designated by AWS
Sub, provided such other Person is licensed to provide Telecommunications
Services in such geographic area under the service marks used by AWS and
qualifies as an agent under any generally applicable standards the Company
establishes for its agents from time to time. Any such agency agreements shall
provide that the Company shall pay the agent a commission at the rate then
generally offered to the Company's agents and shall otherwise be on commercially
reasonable terms. At no time shall there be more than one Person (other than

                                      36
<PAGE>

AWS Sub and its Affiliates) designated by AT&T as a reseller or an agent with
respect to any geographic area within the Territory.

                  (b)   It is the intention of the parties that, in light of AWS
Sub's equity interest in the Company and the other arrangements between AWS Sub
and its Affiliates and the Company (including the roaming revenues anticipated
to be earned by the Company from subscribers of AWS Sub and its Affiliates), the
rates, terms and conditions of Service (as defined in the Resale Agreement)
provided by the Company pursuant to the Resale Agreement or any other agreement
between AWS Sub or such other reseller and the Company shall be at least as
favorable to AWS Sub or such other reseller, taken as a whole, as the rates,
terms and conditions of Service, taken as a whole, provided by the Company to
any other Customer (as defined in the Resale Agreement) and, to the extent
permitted by applicable law, such rates, terms and conditions shall be superior
to those provided to any other Customer. Without limiting the foregoing, the
rate plans offered by the Company pursuant to any Resale Agreement shall be
designed to result in the average actual rate per minute paid by the Reseller
(as defined in the Resale Agreement) for Service being at least 25% below the
weighted average actual rate per minute billed by the Company to its retail
subscribers for access and air time, but excluding revenues for features, taxes,
toll or other non-rate items. The Company and Reseller shall negotiate
commercially reasonable reductions to such resale rate based upon increased
volume commitments (including roaming charges incurred by subscribers of AT&T
and its Affiliates).

                  8.4   LONG DISTANCE SERVICE. To the extent permitted by law,
AT&T will be the Company's preferred provider of long distance service for so
long as the roaming arrangement described in Section 8.2(a) remains in effect.
The Company will purchase all of its long distance service, both for its own
needs and for resale to its customers, from AT&T, and AT&T will provide the
Company with long distance service at the best rates for which the Company
qualifies consistent with AT&T's practice with similarly situated customers,
provided, that at the time a long distance agreement is entered into, the rates
are commercially reasonable and reasonably competitive. Long distance service
may be purchased for the Company from AT&T by Logix Communications as long as
such service is made available to the Company at rates no higher than the rates
offered to the Company by AT&T directly.

                  8.5   EQUIPMENT DISCOUNTS. If reasonably requested by the
Company, AWS will, and will cause its 100% Subsidiaries to, use commercially
reasonable efforts to assist representatives of the Company in obtaining
discounts from any AWS vendor with whom the Company is negotiating for the
purchase of subscriber or infrastructure equipment. AWS shall not be required to
take any such action that AWS determines in its sole discretion is adverse to
its interests.

                  8.6   ROAMING AGREEMENTS. AWS will, and will cause its 100%
Subsidiaries to, use all commercially reasonable efforts to enable the Company
to become a party to the roaming agreements between AWS and its Affiliates and
operators of other wireless systems or, subject to the Company agreeing to the
obligations thereunder, entitled

                                      37
<PAGE>

to the rights and benefits of AWS under such roaming agreements. AWS shall
not be required to take any such action that AWS determines in its sole
discretion is adverse to its interests.

                  8.7   CERTAIN RESTRICTIONS. DCC and its Affiliates will not
offer Telecommunications Services in the Territory except that a special purpose
Subsidiary of DCC with separate management, facilities and financing from DCC
and the Company may construct, own or acquire a controlling interest in, or
manage a communications system which provides Telecommunications Services that
are not Company Communications Services.

                  8.8   OTHER BUSINESS; DUTIES; ETC.

                  (a)   Except as otherwise expressly set forth in this
Agreement, the Members and any Person affiliated with any of the Members may
engage in or possess an interest in other business ventures in which the
Company is not a party, and may engage in any other activities, of every kind
and description (whether or not competitive with the business of the Company
or otherwise affecting the Company), independently or with others in which
the Company is not a party, and shall owe no duty or liability to the
Company, its Members or their Affiliates in connection therewith except as
expressly set forth in this Agreement.

                  (b)   To the extent that, at law or in equity, any Member
or any Affiliate of a Member, or any director, officer, stockholder,
employee, agent or representative of a Member or such Affiliate, would have
duties (including fiduciary duties) and liabilities to the Company or the
Members arising out of this Agreement that are different from or in addition
to those expressly provided in this Agreement, all rights of the other
Members arising out of such duties and liabilities are hereby waived and no
such Person shall be liable to the Company or to any Member for its good
faith reliance on the provisions of this Agreement.

                  (c)   Notwithstanding any provision to the contrary in this
Agreement, to the fullest extent permitted by law, each Representative shall be
deemed the agent of the Member Group which appointed such Person a
Representative, and such Representative shall not be deemed an agent or a
sub-agent of the Company or the other Members or Member Groups and shall have no
duty (fiduciary or otherwise) to the Company or the other Members or Member
Groups.

                  8.9   CONFIDENTIALITY.

                  (a)   Each Member 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 except as contemplated by this Agreement any and all Confidential
Information relating to the Company or any Member and shall not disclose such
information, and shall cause its Agents not to disclose such information, to
anyone

                                      38
<PAGE>

except (x) such Member's Affiliates or Agents who have a need to know such
information in connection with the matters contemplated by this Agreement and
(y) other Persons (such as lenders to the Company or a Member) who have a
bona fide business reason for obtaining such information in connection with
their dealings with the Company or such Member and who agree in writing to
keep in confidence all Confidential Information in accordance with the terms
of this Section. The obligations under this Section shall survive the
termination of this Agreement for a period of three years (or, if earlier, as
to any Person, three years following the date such Person ceases to be a
Member). The foregoing provisions of this Section were negotiated in good
faith by the parties hereto and the parties hereto agree that such provisions
are reasonable and are not more restrictive than is necessary to protect the
legitimate interests of the Members and the Company.

                  (b)   The obligations set forth in paragraph (a) above
shall be inoperative with respect to Confidential Information that (i) is or
becomes generally available to the public other than as a result of
disclosure by the receiving party or its Agents, (ii) was available to the
receiving party on a non-confidential basis prior to its disclosure to the
receiving party or (iii) becomes available to the receiving party or its
agents, provided that such source is not known by the receiving party to be
bound by a confidentiality agreement with the providing party or its Agents.

                  (c)   To the fullest extent permitted by law, if a Member
or any of its Affiliates or Agents breaches or threatens to commit a breach
of this Section, the other Members and the Company shall have the right to
have this Section specifically enforced by any court having jurisdiction, it
being acknowledged and agreed that money damages will not provide an adequate
remedy to such other Members or the Company. Nothing in this Section shall be
construed to limit the right of any Member or the Company to collect money
damages in the event of a breach of this Section; nor to limit the right of
any Member to report the financial condition and results of operations of the
Company to its shareholders, bondholders or to regulatory authorities to the
extent required by law, regulation or the terms of existing instruments.

                  (d)   Anything else in this Agreement or the Related
Agreements notwithstanding, each Member shall have the right to disclose any
information, including Confidential Information of the other Member or such
other Member's Affiliates, in any filing with any regulatory agency, court or
other governmental authority to the extent that the disclosing Member
determines in good faith that it is required by law or regulation, provided
that any such disclosure shall be as limited in scope as possible and shall
only be made after giving the other Member as much notice as practicable of
such required disclosure and an opportunity to contest such disclosure if
possible.

                  8.10  CONVERSION TO CORPORATION.

                  (a)   CONVERSION. The Company will be converted to a
corporation (the "Corporation") in connection with an IPO if the Management
Committee so determines or

                                      39
<PAGE>

(notwithstanding Section 7.3) if a Qualified Member Group so elects under
Section 9.10. The Members will cooperate to minimize any adverse tax
consequences of such conversion.

                  (b)   CONVERSION OF INTERESTS. Upon a conversion of the
Company to a corporation, the Interests of the Qualified Members will be
converted into Class B Common Shares of the Corporation entitling the holders
thereof to ten votes per share. The Interests of other Members will be
converted into Class A Common Shares of the Corporation entitling the holders
thereof to one vote per share. The certificate of incorporation of the
Corporation will provide that (i) Class B Common Shares that are Transferred
to, or held by, Persons that are not Qualified Members will convert
automatically into Class A Common Shares, (ii) Class B Common Shares will be
convertible at any time at the option of the holder into Class A Common
Shares and (iii) if permitted by the exchange on which shares of the
Corporation are listed for trading, Class A Common Shares held by a Qualified
Member will be convertible at any time at the option of the holder into Class
B Common Shares.

                  (c)   STOCKHOLDERS AGREEMENT. Upon a conversion of the Company
to a corporation, the Members will enter into a stockholders agreement
containing, to the extent then applicable, substantially the same terms as this
Agreement, provided, that the stockholders agreement will provide for each
Qualified Member to have registration rights that are substantially similar to
the registration rights set forth in Article 4 to the Stockholder and Investor
Rights Agreement, dated as of January 31, 2000, among DCC and the Persons listed
on Schedule I thereto.

                  8.11  DISPUTE RESOLUTION.

                  (a)   If a dispute arises out of or relating to this Agreement
or the Related Agreements, or the transactions contemplated hereby or thereby,
or the construction, interpretation, performance, breach, termination,
enforceability or validity thereof, 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 date hereof (a
"Dispute"), the dispute resolution processes set forth in this Section 8.11
shall govern the resolution of such dispute.

                  (b)   If a Dispute cannot be resolved by the executives having
primary managerial responsibility for the matter to which the Dispute pertains,
the parties shall attempt in good faith to resolve such Dispute promptly by
negotiation between executives who have authority to settle the Dispute and who
are at the level of the executives who have negotiated this Agreement ("Senior
Party Representatives").

                  (c)   A party may provide any other party notice (a "Dispute
Notice") of any Dispute that has not been resolved in the normal course of
business. Within ten business days after delivery of the Dispute Notice, the
receiving party shall submit to each other party a response (the "Response").
The Dispute Notice and the Response shall each include (a) a statement setting
forth the position of the party providing such notice and a summary of

                                      40

<PAGE>

arguments supporting such position, and (b) the name and title of such
party's Senior Party Representative and any other Persons who will accompany
the Senior Party Representative at the meeting at which the parties will
attempt to settle the Dispute. Within 30 business days after delivery of the
Dispute Notice, the Senior Party Representatives of the parties shall meet at
a mutually acceptable time and place, and thereafter as often as they
reasonably deem necessary, to attempt to resolve the Dispute. All reasonable
requests for information made by one party to another will be honored.

                  (d)   If the Dispute has not been resolved within 50 business
days after delivery of the Dispute Notice, or if the parties fail to meet within
30 business days after delivery of the Dispute Notice, any party may initiate
arbitration of the Dispute as provided below. If no party initiates arbitration
within 60 business days after delivery of the Dispute Notice, then the parties
shall automatically be released from any and all liability for the Dispute.

                  (e)   All negotiations pursuant to this section shall be
treated as compromise and settlement negotiations. Nothing said or disclosed,
nor any document produced, in the course of such negotiations that is not
otherwise independently discoverable shall be offered or received as evidence
or used for impeachment or for any other purpose in any current or future
arbitration. The parties agree that all communications and negotiations
between the parties during the dispute resolution process, any settlements
agreed upon during the dispute resolution process and any information
regarding the other party obtained during the dispute resolution process
(that are not already public knowledge) are confidential and may be disclosed
only to employees and agents of the parties who shall have a "need to know"
the information and who shall have been made aware of the confidentiality
obligations set forth in this Section 8.11, unless the party is required by
law to disclose such information.

                  (f)   If the Dispute is not resolved as provided in
paragraphs (b) through (d) above, then any party may initiate arbitration
proceedings by providing each other party notice of such initiation of
arbitration. The Dispute shall then be settled by arbitration in accordance
with the CPR Non-Administered Arbitration Rules in effect on the date hereof,
by a panel of three arbitrators. Each Party shall select one of the three
arbitrators and the two arbitrators so chosen shall select the third
arbitrator. The arbitrators shall be governed by the United States
Arbitration Act, 9 U.S.C. Sections 1-16, and judgment upon the award rendered
by the arbitrators may be entered by any court having jurisdiction thereof.
The place of arbitration shall be chosen by the three arbitrators. The
arbitrators shall be empowered to award only damages that are recoverable
under the provisions of Article 11, and each party hereby irrevocably waives
any right to recover any other damages with respect to any Dispute. The
arbitrators shall not order pre-hearing discovery of documents or the taking
of depositions, although the arbitrators may compel the attendance of
witnesses and the production of documents at the hearing to the extent
permitted by the CPR Non-Administered Arbitration Rules.

                  (g)   If a party does not provide a Dispute Notice within
one year following the time the party first knows of the existence of the
acts or omissions that give rise to the

                                      41
<PAGE>

Dispute, the party shall be forever estopped from asserting the Dispute
against any other party.

                  (h)   The reasonable out-of-pocket costs (including reasonable
attorneys' fees and expenses) of the prevailing party and the fees of the
arbitrators in any arbitration proceeding pursuant to this Section 8.11 shall be
paid by the other party. The arbitrators shall determine which party is the
prevailing party for purposes of this paragraph, and shall include such
determination in their award. If the arbitrators determine that neither party is
the prevailing party for purposes of this paragraph, then each party shall bear
its own costs and expenses, including attorneys' fees and expenses, and the
parties shall share equally the fees of the arbitrators.

                  (i)   Notwithstanding the foregoing, nothing in this Agreement
shall preclude the parties from seeking injunctive or other equitable relief
from a court with regard to any breach of this Agreement or the Related
Agreements.

                  8.12  DISQUALIFYING TRANSACTION. Upon a Disqualifying
Transaction, AWS may terminate, with respect to all or any portion of the
Territory, the obligations of AT&T and its Affiliates contained in Sections 8.1,
8.2, 8.5 and 8.6, in which event the Voting Interests then held by the AWS
Member Group shall, subject to FCC approval if necessary, immediately and
automatically cease to exist and, accordingly, the AWS Member Group shall no
longer be entitled (x) to exercise governance rights with respect to the Company
(including the right to appoint Representatives to the Management Committee)
except as required by applicable law or (y) to receive information concerning
the Company except for annual and quarterly financial statements pursuant to
Section 6.4. In such event, upon at least 90 days' written notice to AWS given
within 90 days after termination by AWS of the obligations contained in Sections
8.1 and 8.2, the Company will have the right to terminate the Operating
Agreement with respect to the same portion of the Territory.

                       TRANSFER RESTRICTIONS; EXIT RIGHTS;
                            CHANGE OF CONTROL OF DCC

         The provisions of Sections 9.1 through 9.4 shall apply to direct
Transfers of Interests by the Members and Indirect Transfers of Interests by
Persons (including Members) that beneficially own Equity Interests in the
Members.

                  9.1   GENERAL RESTRICTIONS ON TRANSFERS.

                  (a)   PRIOR TO THE THIRD ANNIVERSARY OF THE EFFECTIVE DATE.
Prior to the third anniversary of the Effective Date, Members may not Transfer
Voting Interests or Economic Interests except to other Qualified Members or
members of their respective Affiliate Groups, nor shall Indirect Transfers of
Interests be permitted except in accordance with the provisions of Section 9.4.

<PAGE>

                  (b)   AFTER THE THIRD ANNIVERSARY OF THE EFFECTIVE DATE. On
and after the third anniversary of the Effective Date, Indirect Transfers of
Interests shall not be permitted except in accordance with the provisions of
Section 9.4, and

                  (i)   Members may not Transfer Voting Interests except to
         other Qualified Members or members of their respective Affiliate
         Groups. Any Transfer permitted by the preceding sentence shall not
         be subject to the right of first refusal set forth in Section 9.2 or
         the tag-along right set forth in Section 9.3.

                  (ii)   Members of the AWS Member Group may Transfer in the
         aggregate up to 20% of the Economic Interests acquired by AWS Sub on
         the Effective Date to Persons that are not members of the AWS Affiliate
         Group or the DCC Affiliate Group. Members of the DCC Member Group may
         Transfer in the aggregate up to 20% of the Economic Interests acquired
         by DCC Sub on the Effective Date to Persons that are not members of the
         DCC Affiliate Group or the AWS Affiliate Group. Any Transfer permitted
         by the two preceding sentences shall not be subject to the right of
         first refusal set forth in Section 9.2, but shall be subject to the
         tag-along right set forth in Section 9.3.

                  (iii) If members of the AWS Member Group Transfer in the
         aggregate more than 20% of the Economic Interests acquired by AWS Sub
         on the Effective Date to Persons that are not members of the AWS
         Affiliate Group or the DCC Affiliate Group, or members of the DCC
         Member Group Transfer in the aggregate more than 20% of the Economic
         Interests acquired by DCC Sub on the Effective Date to Persons that are
         not members of the DCC Affiliate Group or the AWS Affiliate Group, the
         Voting Interests then held by the AWS Member Group or the DCC Member
         Group, as the case may be, shall immediately and automatically cease to
         exist and, accordingly, Members that are members of the AWS Member
         Group or the DCC Member Group, as the case may be, shall no longer be
         entitled (x) to exercise governance rights with respect to the Company
         (including the right to appoint Representatives to the Management
         Committee) except as required by applicable law or (y) to receive
         information concerning the Company except for annual and quarterly
         financial statements under Section 6.4. Any Transfer (or portion
         thereof) by a Member of any Member Group, after giving effect to which
         the 20% threshold described in the preceding sentence is crossed, and
         any subsequent Transfer by a Member of such Member Group, shall be
         subject to the right of first refusal set forth in Section 9.2 and the
         tag-along right set forth in Section 9.3.

                  (iv)  Members may not Transfer Voting Interests or Economic
         Interests to a Prohibited Transferee except (after the IPO) pursuant to
         broadly distributed underwritten registered public offerings and Rule
         144 under the Securities Act.

                  (c)   OTHER ENCUMBRANCES ON INTERESTS. Notwithstanding
anything to the contrary in this Agreement or the Act, a Member may not pledge,
hypothecate or otherwise encumber all or any portion of its Interests.

                  9.2   RIGHT OF FIRST REFUSAL.

                  (a)   NOTICE AND EXERCISE OF RIGHT. Subject to the limitations
of Section 9.1(a), if

                  (i)   members of a Member Group (the "Sellers") receive and
         wish to accept a written offer (the "Offer") from a bona fide third
         party (the "Offeror") to purchase some or all of their Economic
         Interests (the "Offered Interests"),

                  (ii)  the consummation of such purchase would result (together
         with any prior Transfers) in the Member Group to which the Sellers
         belong ceasing to be a Qualified Member Group, or this Section 9.2
         otherwise expressly applies pursuant to the terms of this Agreement,
         and

                  (iii) the other Member Group is a Qualified Member Group (it
         being understood that if the other Member Group is not then a Qualified
         Member Group, the Sellers shall not be obligated to comply with the
         provisions of this Section 9.2 or Section 9.3),

then the Sellers shall give notice of such Offer (the "Offer Notice") to the
members of the other Member Group (the "Buyers"), which notice shall identify
the Offeror, enclose a copy of the Offer, and irrevocably offer to the Buyers
the right to purchase (pro rata in accordance with their respective Interests
unless the Buyers otherwise agree) the Offered Interests on the same economic
terms and conditions as specified in the Offer (if they are the only assets
being sold and are being sold for cash) or for cash at their Fair Market Value
(if they are being Transferred in such transaction or series of related
transactions with other assets or for consideration other than cash), provided,
that the Buyers shall be entitled to pay for the Offered Interests with
instruments of indebtedness to the extent the Offer contemplates the delivery of
instruments of indebtedness. The Buyers may exercise their right to purchase the
Offered Interests by notifying the Sellers in writing of their election to
purchase within 21 days after the later of (x) delivery of the Offer Notice and
(y) any determination of Fair Market Value pursuant to Section 9.4(c) or
otherwise.

                  (b)   CLOSING OF PURCHASE. If the Buyers duly elect to
purchase the Offered Interests, the closing of such purchase (the "RoFR
Closing") shall take place on a date agreed to by the Sellers and the Buyers,
but in no event later than 30 days following the exercise by the Buyers of
their election to purchase; provided, that if governmental or regulatory
approval is required for any Buyer to consummate its purchase and has not
been obtained, the RoFR Closing with respect to such purchase may be deferred
until such approval is obtained.

                  (c)   REPRESENTATIONS AT CLOSING. At any RoFR Closing, the
Sellers shall represent and warrant in writing to the Buyers only that the
Sellers (i) are the sole beneficial and record owners of the Offered Interests
and have good and marketable title thereto free and clear of all Liens (other
than restrictions imposed pursuant to this Agreement) and (ii) have full power
and authority to sell the Offered Interests without conflict with the terms of

                                      44
<PAGE>

any law, order or material agreement or instrument binding upon them or their
assets; and the Sellers shall deliver to the Buyers such customary instruments
of assignment with respect to the Offered Interests as may be reasonably
requested by the Buyers.

                  (d)   SALE TO THIRD PARTY. If the Buyers fail to exercise
their right to purchase the Offered Interests, the Sellers may accept the
Offer and sell the Offered Interests to the Offeror; provided, that such sale
shall be at the same price and on the same terms and conditions as specified
in the Offer Notice and otherwise in accordance with Section 9.5. If such
sale is not consummated within 90 days after the expiration of the applicable
time periods specified in paragraph (b) above, such right to sell shall lapse
and Transfers of the Offered Interests shall again be subject to the
provisions of this Section 9.2.

                  (e)   ASSUMPTION OF AGREEMENTS. At any closing with respect
to a sale to a third party, the Offeror shall execute a counterpart to this
Agreement and any Related Agreements to which the Sellers or their Affiliates
are party and shall be bound by the provisions of and assume the obligations
of the Sellers under all such Agreements, provided, that the Management
Agreement shall not be assigned or assumed except in accordance with its
terms. The Sellers and the Offeror shall execute such documents as the Buyers
may reasonably request to evidence such assumption.

                  (f)   PUBLIC SALES. Sales of Interests after the IPO
pursuant to registered public offerings and Rule 144 under the Securities Act
shall be subject to this Section 9.2.

                  9.3   TAG-ALONG RIGHT.

                  (a)   NOTICE AND EXERCISE OF RIGHT. In lieu of exercising its
rights under Section 9.2, or as otherwise expressly provided herein, the Buyers
may, within 21 days after receipt of any Offer Notice, elect by notice to the
Sellers to include their Economic Interests (the "Included Interests") in such
sale on a pro rata basis with the Sellers. Any such sale of Included Interests
shall be made on the same economic terms and conditions as specified in the
Offer (if they are the only assets being sold and are being sold for cash) or
for cash at their Fair Market Value (if they are being Transferred in such
transaction or series of related transactions with other assets or for
consideration other than cash), and the Sellers may not consummate their sale
unless the sale of Included Interests (if any) by the Buyers is consummated
simultaneously in accordance with the terms hereof. If the Buyers do not elect
to participate in such sale, and such sale is not consummated within the
applicable time periods specified in Section 9.2(d), the restrictions contained
in this Section 9.3 shall again become effective, and Economic Interests may not
be Transferred thereafter except in accordance with this Article 9.

                  (b)   REPRESENTATIONS AT CLOSING. At the closing of any
Transfer of Included Interests pursuant to this Section 9.3, (i) the
participating Buyers shall not be required to make any representations and
warranties with respect to the Company or the Business other than those that
the Sellers make to the purchaser, nor shall the Buyers be required to make
any non-compete, non-solicit or similar covenants in connection with such
Transfer, and (ii)

                                      45
<PAGE>

the participating Buyers shall deliver to the purchaser such customary
instruments of assignment with respect to the Included Interests as may be
reasonably requested by the purchaser.

                  (c)   PUBLIC SALES. Sales of Interests after the IPO
pursuant to registered public offerings and Rule 144 under the Securities Act
shall not be subject to this Section 9.3.

                  9.4   INDIRECT TRANSFERS. Subject to Section 9.8, the
provisions of Sections 9.1, 9.2, 9.3, 9.5, 9.6 and 9.7 (the "Specified
Restrictions") shall apply to Indirect Transfers of Interests to the same
extent that they apply to direct Transfers of Interests except as otherwise
provided in this Section 9.4 or elsewhere in this Agreement.

                  (a)   PERCENTAGE TRANSFERRED. A Transfer of any percentage of
the Equity Interests in a member of any Affiliate Group shall be deemed to be a
Transfer by the applicable Member Group of the same percentage of Economic
Interests in the Company. For example, the Transfer of 30% of the capital stock
of AWS Sub or DCC Sub shall be deemed to be the Transfer of 30% of the Economic
Interests in the Company by the AWS Member Group or the DCC Member Group,
respectively. Notwithstanding the foregoing, if at the time of any Indirect
Transfer involving a member of any Affiliate Group, the percentage of the Equity
Interests in such member being Transferred exceeds the percentage of Economic
Interests in the Company then held by the applicable Member Group, such Indirect
Transfer shall be deemed to be a Transfer by such Member Group of the percentage
of Economic Interests in the Company then held by such Member Group. For
example, the Transfer of 60% of the capital stock of AWS Sub or DCC Sub at a
time when they each hold 50% of the Economic Interests in the Company shall be
deemed to be a Transfer of 50% of the Economic Interests in the Company by the
AWS Member Group or the DCC Member Group, respectively.

                  (b)   INDIRECT TRANSFERS WITHIN AN AFFILIATE GROUP. The
Specified Restrictions shall not apply to Transfers of Equity Interests in a
member of any Affiliate Group if immediately after giving effect to such
Transfer such Person remains a member of such Affiliate Group, unless such
Transfer has substantially the same economic effect as a Transfer of Interests
in the Company to a Person that is not a member of such Affiliate Group.

                  (c)   INDIRECT TRANSFERS INVOLVING DCC. So long as the
Interests in the Company beneficially owned by DCC do not account for 50% or
more of the value of DCC, the Specified Restrictions shall not apply to
Transfers of Equity Interests in DCC or any Parent of DCC; provided, that
such Transfers are not designed to circumvent the transfer restrictions
contained herein; and provided, further, that the Specified Restrictions
shall apply, in accordance with Section 9.8, to any Transfer resulting in a
Change of Control of DCC. Notwithstanding Section 9.1(c), DCCLP may pledge
capital stock of DCC to secure indebtedness owing to Bank of America, N.A.
under instruments of indebtedness in effect on the Effective Date, as such
instruments may be amended or replaced from time to time.

                                      46
<PAGE>

                  (d)   INDIRECT TRANSFERS INVOLVING AT&T. The Specified
Restrictions shall not apply to (i) Transfers of Equity Interests in AWS, (ii)
Transfers of Equity Interests in AT&T or (iii) Transfers of Equity Interests by
any direct or indirect shareholder of AWS or AT&T; provided, that such Transfers
are not designed to circumvent the transfer restrictions contained herein.

                  (e)   INDIRECT TRANSFERS INVOLVING JWC. Notwithstanding
anything in this Agreement to the contrary, the Specified Restrictions shall
not apply to Transfers of Equity Interests in DCC by J.W. Childs Equity
Partners, II, L.P. (and its affiliated funds and co-investors listed on
Schedule 9.4).

                  9.5   SUBSTITUTED MEMBERS. Prior to any Transfer of
Interests by a member of any Member Group, the transferor shall deliver to
the members of the other Member Group a notice setting forth the identity of
the transferee and (if applicable) stating that such transferee is a member
of the transferor's Affiliate Group, and shall provide such other information
as the members of the other Member Group may reasonably request in connection
with such Transfer. The transferee shall be admitted as a Member upon
execution of a counterpart to this Agreement evidencing its agreement to be
bound hereby. Upon the admission of any such transferee as a Member, the
transferring Member or Members shall be relieved of any obligation arising
under this Agreement subsequent to such Transfer with respect to the
Interests being transferred (provided that the transferee shall assume all
such obligations), and if the transferring Member no longer holds any
Interests, the transferring Member shall be relieved of its obligations
arising under this Agreement to the extent provided in Section 12.12.

                  9.6   INVALID TRANSFERS VOID. Any purported Transfer of an
Interest or any part thereof not in compliance with the provisions of this
Article 9 shall be void and of no force or effect and the transferring Member
shall be liable to the other Members and the Company for all liabilities,
obligations, damages, losses, costs and expenses (including but not limited to
reasonable attorneys' fees and court costs) arising out of such noncomplying
Transfer.

                  9.7   DETERMINATION OF FAIR MARKET VALUE. The Fair Market
Value of Interests to be transferred or other property received pursuant to
this Agreement shall be determined in the following manner:

                  For purposes of this Section 9.7, Sellers owning a majority of
         the applicable Offered Interests shall have the right to act on behalf
         of the Sellers. Within 15 days after the delivery of the notice
         requiring such determination, the Sellers and the Buyers shall attempt
         in good faith to agree on the Fair Market Value. If the Sellers and the
         Buyers fail within 15 days thereafter to agree thereon, each of the
         Sellers and the Buyers shall deliver a notice to the other appointing
         as its appraiser ("Appraiser") an independent accounting or investment
         banking firm of nationally recognized standing. The Sellers and Buyers
         by mutual agreement shall also appoint a third Appraiser. If after
         appointment of the two Appraisers, the Sellers and Buyers are

                                      47
<PAGE>

         unable to agree upon a third Appraiser, such appointment shall be
         made within fifteen days of the request by the American Arbitration
         Association, or any organization successor thereto, from a panel of
         arbitrators having experience in the appraisal of the type of
         property then the subject of appraisal. The decisions of the three
         Appraisers so appointed and chosen shall be given within 30 days
         after the selection of such third Appraiser. If the determination of
         one Appraiser differs from the middle determination by more than
         twice the amount by which the other determination differs from the
         middle determination, then the determination of such Appraiser shall
         be excluded, the remaining two determinations shall be averaged and
         such average shall be binding and conclusive on the parties;
         otherwise the average of all three determinations shall be binding
         and conclusive. The Sellers' obligation to provide an Offer Notice
         pursuant to Section 9.2(a) shall not be applicable until the date of
         delivery of such determination to the Buyers. The costs of
         conducting any Appraisal Procedure shall be borne as follows: (x)
         the costs of the Appraiser designated by the Sellers and other costs
         separately incurred by the Sellers shall be borne by the Sellers;
         (y) the costs of the Appraiser designated by the Buyers and other
         costs separately incurred by the Buyers shall be borne by the
         Buyers; and (z) the costs of the third Appraiser, if any, shall be
         shared equally by the Sellers and the Buyers.

                  9.8   CHANGE OF CONTROL OF DCC. Notwithstanding anything in
this Agreement to the contrary:

                  (a)   PROHIBITED TRANSFEREE, ETC. If there is a Change of
Control of DCC in which a Prohibited Transferee (alone or as part of a "group"
as such term is used in Sections 13(d) and 14(d) of the Exchange Act and the
regulations thereunder) or, prior to the second anniversary of the Effective
Date, a Person that is not a Prohibited Transferee (alone or as part of a
"group" as such term is used in Sections 13(d) and 14(d) of the Exchange Act and
the regulations thereunder) acquires control of DCC, and either the Company is a
limited liability company and the AWS Member Group is a Qualified Member Group,
or the Company has converted to a corporation and members of the AWS Affiliate
Group retain in the aggregate capital stock in such corporation representing at
least 50% of the Economic Interests that AWS Sub acquired on the Effective Date,
then

                  (i)   If it does not elect to exercise its rights under
         Section 9.2 or 9.3, the AWS Member Group may initiate the Buy-Sell
         Procedure (except that the AWS Member Group shall have the right but
         not the obligation to require that DCC propose the cash purchase
         price for all of the Interests of the AWS Member Group) for 90 days
         after the second anniversary of the Effective Date,

                  (ii)  from and after the effective date of such Change of
         Control of DCC, the DCC Member Group shall lose the right to appoint
         one of its two Representatives to the Management Committee (and such
         Representative shall forthwith resign or be deemed removed as such) and
         the AWS Member Group shall thereupon have the right to appoint three of
         the four Representatives, and

                                      48
<PAGE>

                  (iii) from and after the effective date of such Change of
         Control of DCC, subject to Section 9.1(b)(iii), the Significant Matters
         that the DCC Member Group will have the right to approve shall be those
         set forth on Exhibit A.

                  (b)   STATUS OF CONTROL PERSON. Except as otherwise provided
in this Section 9.8, any Person referred to in paragraph (a) above that acquires
control of DCC shall be treated as the Dobson Group for all purposes of this
Agreement, and if the DCC Member Group was a Qualified Member Group immediately
prior to the time of the Change of Control of DCC, and for so long thereafter as
it qualifies as such hereunder, it shall also be considered a Qualified Member
Group immediately after the Change of Control.

                  9.9   BUY-SELL PROCEDURE.

                  (a)   AFTER THE FIFTH ANNIVERSARY OF THE EFFECTIVE DATE. After
the fifth anniversary of the Effective Date, whether or not an IPO has occurred,
a Member Group may initiate a buy-sell procedure (the "Buy-Sell Procedure") by
giving the other Member Group a notice referring to this Section 9.9(a) (the
"Section 9.9(a) Notice"), which notice shall specify a cash purchase price per
Interest or per share, as applicable, for all of the Interests in the Company
then held by the other Member Group, and contain an irrevocable offer to
purchase such Interests, and to sell all of the Interests in the Company then
held by the initiating Member Group, at such price. The non-initiating Member
Group may exercise its right to purchase or sell by notifying the initiating
Member Group of its election within 90 days after delivery of the Section 9.9(a)
Notice; provided, that the DCC Member Group may not initiate the Buy-Sell
Procedure, or elect to buy in the event that the AWS Member Group initiates the
Buy-Sell Procedure, without concurrently providing to the AWS Member Group a
firm commitment, including a "material adverse change" condition (which may
include a condition relating to disruption of the financial markets), reasonably
acceptable to the AWS Member Group, from a financial institution reasonably
acceptable to the AWS Member Group, to underwrite the purchase price. The
closing of any such purchase and sale will occur within 90 days after the end of
such 90-day period, subject to extension for obtaining by Final Order any
regulatory approvals.

                  (b)   IN CONNECTION WITH OVERLAP IN SERVICE COVERAGE. The AWS
Member Group may initiate the Buy-Sell Procedure at any time if (x) the Company
is then offering, in service areas covering 15% or more of the Company's Pops,
Company Communications Services that are not Mobile Wireless Services and (y)
AWS or its Affiliates are then offering, or have a good faith intention to begin
offering and have taken material steps towards offering, in such service areas,
Telecommunications Services that could reasonably be considered by subscribers
to be equivalent to, or a substitute for, such Company Communications Services
that are not Mobile Wireless Services. Such right will be exercisable by giving
the DCC Member Group a notice referring to this Section 9.9(b) (the "Section
9.9(b) Notice") and signed by a senior executive officer of AWS, which notice
shall (x) describe in reasonable detail the competing services that AWS or its
Affiliates are then offering or intending in good faith to offer and the steps
they have taken towards offering such services, (y) specify a cash purchase
price per Interest or per share, as applicable, for all

                                      49
<PAGE>

of the Interests in the Company then held by the DCC Member Group, and (z)
contain an irrevocable offer to purchase such Interests, and to sell all of
the Interests in the Company then held by the AWS Member Group, at such
price. The DCC Member Group may exercise its right to purchase or sell by
notifying the AWS Member Group of its election within 90 days after delivery
of the Section 9.9(b) Notice; provided, that the DCC Member Group may not
elect to purchase without concurrently providing to the AWS Member Group a
firm commitment, including a "material adverse change" condition (which may
include a condition relating to disruption of the financial markets),
reasonably acceptable to the AWS Member Group, from a financial institution
reasonably acceptable to the AWS Member Group, to underwrite the purchase
price. The closing of any such purchase and sale will occur within 90 days
after the end of such 90-day period, subject to extension for regulatory
approvals.

                  (c)   IN THE EVENT OF CHANGE OF CONTROL OF DCC. If, in
connection with a Change of Control of DCC, the AWS Member Group does not elect
to exercise its right to initiate the Buy-Sell Procedure pursuant to Section
9.8(a)(i), if applicable, or its right of first refusal or tag-along right under
Section 9.2 or 9.3, then, at any time during the 90-day period beginning on the
later of the second anniversary of the Effective Date and 90 days following the
expiration of the last of such rights, the DCC Member Group will have the right
to initiate the Buy-Sell Procedure by giving the AWS Member Group a notice
referring to this Section 9.9(c) (the "Section 9.9(c) Notice"), which notice
shall specify a cash purchase price per Interest or per share, as applicable,
for all of the Equity Interests in the Company then held by the AWS Member
Group, and contain an irrevocable offer to purchase such Equity Interests, and
to sell all of the Equity Interests in the Company then held by the DCC Member
Group, at such price; provided, that the DCC Member Group may not initiate the
Buy-Sell Procedure without concurrently providing to AWS Member Group a firm
commitment, including a "material adverse change" condition (which may include a
condition relating to disruption of the financial markets), reasonably
acceptable to the AWS Member Group, from a financial institution reasonably
acceptable to the AWS Member Group, to underwrite the purchase price. The AWS
Member Group may exercise its right to purchase or sell by notifying the DCC
Member Group of its election within 90 days after delivery of the Section 9.9(c)
Notice. The closing of any such purchase and sale will occur within 90 days
after the end of such 90-day period, subject to extension for regulatory
approvals.

                  (d)   REPRESENTATIONS AT CLOSING. At the closing of any
purchase and sale pursuant to the Buy-Sell Procedure, the selling Member Group
shall represent and warrant in writing to the non-selling Member Group that the
selling Members (i) are the sole beneficial and record owners of the Interests
being sold and have good and marketable title thereto free and clear of all
Liens (other than restrictions imposed pursuant to this Agreement) and (ii) have
full power and authority to sell the Interests being sold without conflict with
the terms of any law, order or material agreement or instrument binding upon
them or their assets; and the selling Members shall deliver to the non-selling
Member Group such customary instruments of assignment with respect to the
Interests being sold as may be reasonably requested by the non-selling Member
Group.

                  (e)   TERMINATION OF AGREEMENT. Upon the consummation of a
purchase and sale transaction pursuant to the Buy-Sell Procedure, the Management
Agreement and the agreements set forth in Sections 8.1, 8.2, 8.5 and 8.6 will
terminate immediately, and the Operating Agreement will terminate on the later
of (a) the tenth anniversary of the Effective Date and (b) the second
anniversary of the consummation of such purchase and sale transaction.

                  9.10  IPO DEMAND. After the fifth anniversary of the Effective
Date, any Qualified Member Group may by notice to the Company and the other
Qualified Member Group (if any) elect (the "Section 9.10 Election") to require
the Company to convert to a corporation in accordance with Section 8.10 and to
effect an IPO of not less than 10% nor more than 20% of the Corporation's Class
A Common Stock, underwritten by an underwriter selected by the Management
Committee, and otherwise conducted in accordance with the registration
procedures referred to in Section 8.10(c); provided, that the non-electing
Qualified Member Group (if any) may (i) defer the Section 9.10 Election for up
to 180 days on one occasion during any 12-month period and (ii) preempt the
Section 9.10 Election by initiating the Buy-Sell Procedure within 30 days after
such Election is made, provided, that the DCC Member Group may not initiate the
Buy-Sell Procedure, or elect to buy in the event that the AWS Member Group
initiates the Buy-Sell Procedure, without concurrently providing to AWS Member
Group a firm commitment, including a "material adverse change" condition (which
may include a condition relating to disruption of the financial markets),
reasonably acceptable to AWS Member Group, from a financial institution
reasonably acceptable to AWS Member Group, to underwrite the purchase price.

                           DISSOLUTION AND TERMINATION

                  10.1  NO WITHDRAWAL. Except as expressly provided in this
Agreement or as otherwise provided by law, no Member shall have the right, and
each Member hereby agrees not, to dissolve, terminate or liquidate the Company,
or to resign or withdraw as a Member.

                  10.2  DISSOLUTION. The Company shall be dissolved upon the
written determination of the Management Committee to dissolve the Company, but
only on the effective date of dissolution specified by the Management Committee
in such determination.

                  10.3  PROCEDURES UPON DISSOLUTION.

                  (a)   GENERAL. In the event the Company dissolves it shall
commence winding up pursuant to the appropriate provisions of the Act and the
procedures set forth in this Section 10.3. Notwithstanding the dissolution of
the Company, until the winding up of the Company's affairs is completed, the
business of the Company and the affairs of the Members, as such, shall continue
to be governed by this Agreement.

                  (b)   CONTROL OF WINDING UP. The winding up of the Company
shall be conducted under the direction of the Management Committee or such other
Person as may be

                                      51
<PAGE>

designated by a court of competent jurisdiction (herein sometimes referred to
as the "Liquidator"); provided that any Member whose breach of this Agreement
shall have caused the dissolution of the Company (and the Representatives
appointed by such Member) shall not participate in the control of the winding
up of the Company; and provided further, that if the dissolution is caused by
entry of a decree of judicial dissolution, the winding up shall be carried
out in accordance with such decree.

                  (c)   MANNER OF WINDING UP. The Company shall engage in no
further business following dissolution other than that necessary for the orderly
winding up of business and distribution of assets. The Company's maintenance of
offices shall not be deemed a continuation of business for purposes of this
Section 10.3. Upon dissolution of the Company, the Liquidator shall, subject to
paragraph (a) above, first attempt to distribute assets in kind if it can obtain
the consent of each of the Members and, to the extent necessary, the creditors
of the Company. If such consent is not obtained, the Liquidator shall sell the
Company or all the Company's property in such manner and on such terms as it
deems fit, consistent with its fiduciary responsibility and having due regard to
the activity and condition of the relevant market and general financial and
economic conditions. Each Member shall share Profits, Losses and other items
after the dissolution of the Company and during the period of winding up in the
same manner as described in Article 4.

                  (d)   APPLICATION OF ASSETS. Upon dissolution of the Company,
the Company's assets (which shall, after the sale or sales referenced in
paragraph (c) above, consist of the proceeds thereof) shall be applied as
follows:

                  (i)   CREDITORS. To creditors, including Members and
         Representatives who are creditors, to the extent otherwise permitted by
         law, in satisfaction of liabilities of the Company (whether by payment
         or the reasonable provision for the payment thereof). Any reserves set
         up by the Liquidator may be paid over by the Liquidator to an escrow
         agent or trustee, to be held in escrow or trust for the purpose of
         paying any such contingent or unforeseen liabilities or obligations,
         and, at the expiration of such period as the Liquidator may deem
         advisable, such reserves shall be distributed to the Members or their
         assigns in the manner set forth in paragraph (ii) below.

                  (ii)  MEMBERS. By the end of the taxable year in which the
         liquidation occurs (or, if later, within 90 days after the date of such
         liquidation), to the Members in proportion to the positive balances of
         their respective Capital Accounts, as determined after taking into
         account all Capital Account adjustments for the taxable year during
         which the liquidation occurs (other than those made pursuant to this
         paragraph).

                  10.4  TERMINATION. Upon completion of the winding up of the
Company and the distribution of all Company assets, the Company's affairs shall
terminate and the Members shall cause to be executed and filed any and all
documents required by the Act to effect the termination of the Company.

                         EXCULPATION AND INDEMNIFICATION

                  11.1  NO PERSONAL LIABILITY.

                  (a)   Except as otherwise provided by the Act, the debts,
obligations and liabilities of the Company, whether arising in contract, tort or
otherwise, shall be solely the debts, obligations and liabilities of the
Company, and no Indemnified Person (as defined in paragraph (b) below) shall be
obligated personally for any such debt, obligation or liability of the Company
solely by reason of being an Indemnified Person.

                  (b)   No Representative, Member or its Affiliates, or any of
their respective shareholders, directors, officers, employees, agents, members,
managers, or partners (each, an "Indemnified Person") shall be liable,
responsible or accountable in damages or otherwise to the Company or to any
other Indemnified Person for any act or omission performed or omitted by an
Indemnified Person in connection with the transactions contemplated hereby,
whether for mistake of judgment or negligence or other action or inaction,
unless such action or omission constitutes willful misconduct, gross negligence
or bad faith. Each Indemnified Person may consult with counsel, accountants and
other experts in respect of the affairs of the Company and such Indemnified
Person shall be fully protected and justified in any action or inaction which is
taken in good faith in accordance with the advice or opinion of such counsel,
accountants or other experts, provided that they shall have been selected with
reasonable care.

                  11.2  INDEMNIFICATION BY COMPANY. To the maximum extent
permitted by applicable law, the Company shall protect, indemnify, defend and
hold harmless each Indemnified Person for any acts or omissions performed or
omitted by an Indemnified Person (in its capacity as such) unless such action or
omission constituted willful misconduct, gross negligence or bad faith. The
indemnification authorized under this Section shall include payment on demand
(with appropriate evidence of the amounts claimed) of reasonable attorneys' fees
and other expenses incurred in connection with, or in settlement of, any legal
proceedings between the Indemnified Person and a third party and the removal of
any Liens affecting any property of the Indemnified Person. Such indemnification
rights shall be in addition to any and all rights, remedies and recourse to
which any Indemnified Person shall be entitled, whether or not pursuant to the
provisions of this Agreement, at law or in equity. The indemnities provided for
in this Section 11.2 shall be recoverable only from the assets of the Company,
and there shall be no recourse to any Member or other Person for the payment of
such indemnities.

                  11.3  NOTICE AND DEFENSE OF CLAIMS.

                  (a)   NOTICE OF CLAIM. If any action, claim or proceeding
("Claim") shall be brought or asserted against any Indemnified Person in respect
of which indemnity may be sought from the Company under Section 11.2, the
Indemnified Person shall give prompt written notice of such Claim to the
Company, which may assume the defense thereof,

                                      53
<PAGE>

including the employment of counsel reasonably satisfactory to the
Indemnified Person and the payment of all of such counsel's fees and
expenses; provided that any delay or failure to so notify the Company shall
relieve the Company of its obligations hereunder only to the extent, if at
all, that it is prejudiced by reason of such delay or failure. Any such
notice shall refer to Section 11.2 and describe in reasonable detail the
facts and circumstances of the Claim being asserted.

                  (b)   DEFENSE BY THE COMPANY. In the event that the Company
undertakes the defense of the Claim, the Company will keep the Indemnified
Person advised as to all material developments in connection with any Claim,
including, but not limited to, promptly furnishing the Indemnified Person with
copies of all material documents filed or served in connection therewith. The
Indemnified Person shall have the right to employ one separate firm per
jurisdiction with respect to any of the foregoing Claims and to participate in
the defense thereof, but the fees and expenses of such firm shall be at the
expense of the Indemnified Person unless both the Indemnified Person and the
Company are named as parties and representation by the same counsel is
inappropriate due to actual differing interests between them; provided that
under no circumstances shall the Company be liable for the fees and expenses of
more than one law firm per jurisdiction in any of the foregoing Claims for the
Indemnified Persons, taken collectively and not separately. The Company may,
without the Indemnified Person's consent, settle or compromise any Claim or
consent to the entry of any judgment if such settlement, compromise or judgment
involves only the payment of money damages by the Company (which payment is made
or adequately provided for at the time of such settlement, compromise or
judgment) or provides for the unconditional release by the claimant or plaintiff
of the Indemnified Person and its Affiliates from all liability in respect of
such Claim and does not impose injunctive relief against any of them. The
Indemnified Person shall provide reasonable assistance to the Company in the
defense of the Claim. As between the Company, on the one hand, and the
Indemnified Persons, on the other hand, any matter that is not agreed to
unanimously by the Indemnified Persons shall be determined by the Indemnified
Person that is a party to this Agreement.

                  (c)   DEFENSE BY THE INDEMNIFIED PERSON. In the event that the
Company, within 20 business days after receiving written notice of any such
Claim, fails to assume the defense thereof, the Indemnified Person shall have
the right, subject to the right of the Company thereafter to assume such defense
pursuant to the provisions of this Article 11, to undertake the defense,
compromise or settlement of such Claim for the account of the Company.

                  (d)   ADVANCEMENT OF EXPENSES. Unless the Indemnifying Party
shall have assumed the defense of any Claim pursuant to paragraph (b) above, the
Company shall advance to the Indemnified Person any of its reasonable attorneys'
fees and other costs and expenses incurred in connection with the defense of any
such Claim. Each Indemnified Person shall agree in writing prior to any such
advancement, that in the event he or it receives any such advance, such
Indemnified Person shall reimburse the Company for such fees, costs, and
expenses to the extent that it shall be determined that he or it was not
entitled to indemnification under this Article 11.

                                      54
<PAGE>

                  (e)   CONTRIBUTION. Notwithstanding any of the foregoing to
the contrary, the provisions of this Article 11 shall not be construed so as to
provide for the indemnification of any Indemnified Person for any liability to
the extent (but only to the extent) that such indemnification would be in
violation of applicable law or to the extent such liability may not be waived,
modified, or limited under applicable law, but shall be construed so as to
effectuate the provisions of this Article 11 to the fullest extent permitted by
law; provided, that if and to the extent that the Company's indemnification
obligation under this Article 11 is unenforceable for any reason, the Company
hereby agrees to make the maximum contribution permissible under applicable law
to the payment and satisfaction of the losses of the Indemnified Person, except
to the extent such losses are found in a final, nonappealable judgment by a
court of competent jurisdiction to have resulted from the Indemnified Person's
gross negligence or willful misconduct.

                                   ARTICLE 12
                                  MISCELLANEOUS

                  12.1   ENTIRE AGREEMENT. This Agreement and the Related
Agreements, together with any schedules and exhibits hereto and thereto, contain
the entire agreement and understanding of the Members relating to the subject
matter hereof and supersede all prior negotiations, proposals, offers,
agreements and understandings (written or oral) relating to such subject matter,
including the letter agreement and term sheet attached thereto dated October 5,
1999 among AWS, DCC and DCCLP.

                  12.2   AMENDMENT; WAIVER. Neither this Agreement nor any
provision hereof may be amended or modified except in a writing signed by each
of the Qualified Members; PROVIDED, that any amendment or modification that
adversely affects a non-Qualified Member shall require the consent of such
Member. No failure or delay of any Member in exercising any power or right
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right or power, or any abandonment or discontinuance of
steps to enforce any such right or power, preclude any other further exercise
thereof or the exercise of any other right or power. No waiver by any Member of
any departure by any other Member from any provision of this Agreement shall be
effective unless the same shall be in a writing signed by the Member against
which enforcement of such waiver or consent is sought, and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which it was given. No notice or similar communication by any Member
to another shall entitle such other Member to any other or further notice or
similar communication in similar or other circumstances, except as specifically
provided herein.

                  12.3   SPECIFIC PERFORMANCE. The Members acknowledge that
money damages may not be an adequate remedy for violations of this Agreement
and that any Member may, in its sole discretion, in an arbitration or a court
of competent jurisdiction, to the extent permitted hereunder, apply for
specific performance or injunctive or other relief as such arbitration or
court may deem just and proper in order to enforce this Agreement or to

                                      55
<PAGE>

prevent violation hereof and, to the extent permitted by applicable law, each
Member waives any objection to the imposition of such relief.

                  12.4  REMEDIES CUMULATIVE. All rights, powers and remedies
provided under this Agreement or otherwise available in respect hereof at law or
in equity shall, unless otherwise specifically provided herein, be cumulative
and not alternative, and the exercise or beginning of the exercise of any right,
power or remedy thereof by a Member shall not preclude the simultaneous or later
exercise of any other such right, power or remedy by such Member.

                  12.5   SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon and shall inure to the benefit of the Members and their respective
successors and permitted assigns. No Member may assign its rights or delegate
its duties under this Agreement without the written consent of the other Members
except to the extent expressly provided in this Agreement.

                  12.6   NO THIRD PARTY BENEFICIARIES. This Agreement is entered
into solely for the benefit of the Members and no Person other than the Members,
their respective successors and permitted assigns, their Affiliates to the
extent expressly provided herein, and (to the extent provided in Article 11) the
Persons entitled to indemnification pursuant to Article 11, may exercise any
right or enforce any obligation hereunder.

                  12.7   FURTHER ASSURANCES. Each Member will execute and
deliver such further documents and take such further actions as any other
Member may reasonably request consistent with the provisions hereof in order
to effect the intent and purposes of this Agreement.

                  12.8   NOTICES. All notices or other communications hereunder
shall be in writing and shall be deemed to have been duly given or made (i) upon

                  12.12  DISPOSITION OF INTERESTS. Upon the sale or other
disposition by a Person of all its Interests in the Company, following which
such Person and Affiliate thereof is no longer a Member of the Company, this
Agreement shall terminate as to such Member and its Affiliates except as
provided in Section 12.13.

                  12.13  SURVIVAL OF RIGHTS AND DUTIES. Termination of this
Agreement for any reason shall not relieve any Member of any liability which at
the time of termination has already accrued to such Member or which thereafter

transfer of control is made; and (b) if such transfer of control requires
notification to the FCC after it has occurred, the Member taking such action
(or whose Member Group has taken such action) shall be responsible for
assuring that all required notifications to the FCC have been filed. In any
such event, the responsible Member shall assure that all required
applications and/or notifications are timely filed and are accurate and

                   AMENDED AND RESTATED SUPPLEMENTAL AGREEMENT

         Amended and Restated Supplemental Agreement, dated as of February 25,
2000, among AT&T Wireless Services, Inc., a Delaware corporation ("AWS"), Dobson
Communications Corporation, an Oklahoma corporation ("DCC"), Dobson CC Limited
Partnership and the other signatories hereto. Capitalized terms used but not
defined herein have the meanings given to such terms in the LLC Agreement
referred to below.

         Whereas, AT&T Wireless Services JV Co., a Delaware corporation ("AWS
Sub") and a wholly owned subsidiary of AWS, and Dobson JV Company, an Oklahoma
corporation ("DCC Sub") and a wholly owned subsidiary of DCC, are entering into
a Second Amended and Restated Limited Liability Company Agreement, dated as of
the date hereof (the "LLC Agreement"), relating to ACC Acquisition LLC, a
Delaware limited liability company (the "Company"); and

         Whereas, the parties hereto entered into a Supplemental Agreement,
dated as of January 31, 2000 (the "Original Agreement"), and are entering into
this Agreement as a material inducement to the execution and delivery of the LLC
Agreement by AWS Sub and DCC Sub.

         Now, therefore, in consideration of the mutual promises hereinafter set
forth, the parties hereby agree, and the Original Agreement is hereby amended
and restated in its entirety, as follows:

         1.   TRANSFER RESTRICTIONS. The parties hereby acknowledge the
restrictions on Transfers of Interests in the Company set forth in Article 9 of
the LLC Agreement, including but not limited to the restrictions on Indirect
Transfers set forth in Section 9.4 thereof, and agree to be bound by such
provisions to the same extent as if they had executed the LLC Agreement.

         2.   NOTICE OF TRANSFER. Prior to any Indirect Transfer of Interests
by a party hereto, the transferor shall, if the Specified Restrictions apply
to such Transfer pursuant to Section 9.4 of the LLC Agreement, deliver to the
other parties hereto a notice setting forth the identity of the transferee
and (if applicable) stating that such transferee is a member of the
transferor's Affiliate Group, and shall provide such other information as the
other parties hereto may reasonably request in connection with such Transfer.
Concurrently with any such Indirect Transfer, the transferor shall cause the
transferee to execute, and distribute to the other parties hereto, a
counterpart to this Agreement evidencing the transferee's agreement to be
bound hereby.

         3.   MISCELLANEOUS. This agreement (i) together with the LLC Agreement
contains the entire agreement among the parties hereto as to the subject matter
set forth in paragraph 1 above, (ii) shall be governed by, and construed in
accordance with, the laws of the State of Delaware, without giving effect to
Delaware's conflict of law rules, and (iii) may be executed in any number of
counterparts, all of which when taken together shall constitute one and the same
instrument and any of the parties hereto may execute this letter agreement by
signing any such counterpart.
