Agreement") dated as of January 18, 2000, with Bank of America, N.A., as
Administrative Agent (including its permitted successors and assigns in such
capacity, the "Administrative Agent"), and the Lenders now or hereafter party to
the Credit Agreement (including their respective permitted successors and
assigns, the "Lenders"), which Credit Agreement amends, restates, and
consolidates the Existing Credit Agreements (as such term is described and
defined in the Credit Agreement).

      B. To assure payment and performance of the Obligation under the Existing
DOC Credit Agreements, certain Guarantors executed Guaranties (including without
limitation, the guaranties described on Part A of Schedule 1, the "Existing DOC
Guaranties").

      C. To assure payment and performance of the Obligation under the Existing
DCOC Credit Agreements, certain Guarantors executed Guaranties (including
without limitation, the guaranties on Part B of Schedule 1, the "Existing DCOC
Guaranties").

      D. In connection with the execution of and as a condition of the
effectiveness of, the Credit Agreement, the Existing DOC Guaranties and the
Existing DCOC Guaranties are required to be (and are hereby) amended, restated,
and consolidated in their entirety.

      E. This Guaranty is integral to the transactions contemplated by the Loan
Documents, and the execution and delivery hereof, is a condition precedent to
Lenders' obligations to extend credit under the Loan Documents.

      ACCORDINGLY, for adequate and sufficient consideration, the receipt and
adequacy of which are hereby acknowledged, Guarantor guarantees to
Administrative Agent and Lenders the prompt payment of the Guaranteed Debt
(defined below) as follows:

      10 DEFINITIONS. Terms defined in the Credit Agreement have the same
meanings when used, unless otherwise defined, in this Guaranty. As used in this
Guaranty:

      Borrower means Borrower, Borrower as a debtor-in-possession, and any
receiver, trustee, liquidator, conservator, custodian, or similar party
appointed for Borrower or for all or substantially all of Borrower's assets
under any Debtor Relief Law.

      Credit Agreement is defined in the recitals to this Guaranty.

      Existing Guaranties is defined in the recitals to this Guaranty.

<PAGE>

      Guaranteed Debt means, collectively, (a) the Obligation and (b) all
present and future costs, attorneys' fees, and expenses reasonably incurred by
Administrative Agent or any Lender to enforce Borrower's, Guarantor's, or any
other obligor's payment of any of the Guaranteed Debt, including, without
limitation (to the extent lawful), all present and future amounts that would
become due but for the operation of ss.ss. 502 or 506 or any other provision of
Title 11 of the United States Code and all present and future accrued and unpaid
interest (including, without limitation, all post-maturity interest and any
post-petition interest in any proceeding under Debtor Relief Laws to which
Borrower or Guarantor becomes subject). Notwithstanding the foregoing, to the
extent Guarantor is a Cellular Partnership Obligor, the Guaranteed Debt shall be
limited, on any date of determination, to the amount of Debt owed by Guarantor
to any Company, whether or not such Debt is evidenced by a Cellular Partnership
Promissory Note.

      Guarantor is defined in the preamble to this Guaranty.

      Lender means, individually, or Lenders means, collectively, on any date of
determination, Administrative Agent and Lenders.

      Subordinated Debt means all present and future obligations of any Company
to Guarantor, whether those obligations are (a) direct, indirect, fixed,
contingent, liquidated, unliquidated, joint, several, or joint and several, (b)
due or to become due to Guarantor, (c) held by or are to be held by Guarantor,
(d) created directly or acquired by assignment or otherwise, or (e) evidenced in
writing.

      20 GUARANTY. This is an absolute, irrevocable, and continuing guaranty of
payment, not collection, and the circumstance that at any time or from time to
time the Guaranteed Debt may be paid in full does not affect the obligation of
Guarantor with respect to the Guaranteed Debt incurred after that. This Guaranty
remains in effect until the Guaranteed Debt is fully paid and performed, all
commitments to extend any credit under the Loan Documents have terminated, all
LCs have expired or been terminated, and all Financial Hedges with any Lender or
Affiliate of any Lender have expired. Guarantor may not rescind or revoke its
obligations with respect to the Guaranteed Debt. Notwithstanding any contrary
provision, it is the intention of Guarantor, Lenders, and Administrative Agent
that the amount of the Guaranteed Debt guaranteed by Guarantor by this Guaranty
shall be in, but not in excess of, the maximum amount permitted by fraudulent
conveyance, fraudulent transfer, or similar Laws applicable to Guarantor.
Accordingly, notwithstanding anything to the contrary contained in this Guaranty
or any other agreement or instrument executed in connection with the payment of
any of the Guaranteed Debt, the amount of the Guaranteed Debt guaranteed by
Guarantor by this Guaranty shall be limited to an aggregate amount equal to the
largest amount that would not render Guarantor's obligations hereunder subject
to avoidance under Section 548 of the United States Bankruptcy Code or any
comparable provision of any applicable state Law.

      30 CONSIDERATION. Guarantor represents and warrants that its liability
under this Guaranty may reasonably be expected to directly or indirectly benefit
it.

      40 CUMULATIVE RIGHTS. If Guarantor becomes liable for any indebtedness
owing by Borrower to Administrative Agent or any Lender, other than under this
Guaranty, that liability may not be in any manner impaired or affected by this
Guaranty. The Rights of Administrative Agent or Lenders under this Guaranty are
cumulative of any and all other Rights that Administrative Agent or Lenders may
ever have against Guarantor. The exercise by Administrative Agent or Lenders of
any Right under this Guaranty or otherwise does not preclude the concurrent or
subsequent exercise of any other Right.

      50 PAYMENT UPON DEMAND. If a Default exists, Guarantor shall, on demand
and without further notice of dishonor and without any notice having been given
to Guarantor previous to that demand of either the acceptance by Administrative
Agent or Lenders of this Guaranty or the creation or incurrence

<PAGE>

of any Guaranteed Debt, pay the amount of the Guaranteed Debt then due and
payable to Administrative Agent and Lenders; provided that, if a Default exists
and Administrative Agent or Lenders cannot, for any reason, accelerate the
Obligation, then the Guaranteed Debt shall be, as among Guarantor,
Administrative Agent, and Lenders, a fully matured, due, and payable obligation
of Guarantor to Administrative Agent and Lenders. It is not necessary for
Administrative Agent or Lenders, in order to enforce that payment by Guarantor,
first or contemporaneously to institute suit or exhaust remedies against
Borrower or others liable on any Guaranteed Debt or to enforce Rights against
any Collateral securing any Guaranteed Debt.

      60 SUBORDINATION. The Subordinated Debt is expressly subordinated to the
full and final payment of the Guaranteed Debt. Guarantor agrees not to accept
any payment of any Subordinated Debt from any Company if a Default exists. If
Guarantor receives any payment of any Subordinated Debt in violation of the
foregoing, Guarantor shall hold that payment in trust for Administrative Agent
and Lenders and promptly turn it over to Administrative Agent, in the form
received (with any necessary endorsements), to be applied to the Guaranteed
Debt.

      70 SUBROGATION AND CONTRIBUTION. Until payment in full of the Guaranteed
Debt, the termination of the Obligation of Lenders to extend credit under the
Loan Documents, and expiration of all Financial Hedges between Communications,
Guarantor, or any Company and any Lender or any Affiliate of any Lender, (a)
Guarantor may not assert, enforce, or otherwise exercise any Right of
subrogation to any of the Rights or Liens of Administrative Agent or Lenders or
any other beneficiary against Borrower or any other obligor on the Guaranteed
Debt or any Collateral or other security or any Right of recourse,
reimbursement, subrogation, contribution, indemnification, or similar Right
against Borrower or any other obligor on any Guaranteed Debt or any guarantor of
it, (b) Guarantor defers all of the foregoing Rights (whether they arise in
equity, under contract, by statute, under common law, or otherwise), and (c)
Guarantor defers the benefit of, and subordinates any Right to participate in,
any Collateral or other security given to Administrative Agent or Lenders or any
other beneficiary to secure payment of any Guaranteed Debt.

      80 NO RELEASE. Guarantor's obligations under this Guaranty may not be
released, diminished, or affected by the occurrence of any one or more of the
following events: (a) any taking or accepting of any other security or assurance
for any Guaranteed Debt; (b) any release, surrender, exchange, subordination,
impairment, or loss of any Collateral securing any Guaranteed Debt; (c) any full
or partial release of the liability of any other obligor on the Obligation,
except for any final release resulting from payment in full of such Obligation;
(d) the modification of, or waiver of compliance with, any terms of any other
Loan Document; (e) the insolvency, bankruptcy, or lack of corporate or
partnership power of any other obligor at any time liable for any Guaranteed
Debt, whether now existing or occurring in the future; (f) any renewal,
extension, or rearrangement of any Guaranteed Debt or any adjustment,
indulgence, forbearance, or compromise that may be granted or given by
Administrative Agent or any Lender to any other obligor on the Obligation; (g)
any neglect, delay, omission, failure, or refusal of Administrative Agent or any
Lender to take or prosecute any action in connection with the Guaranteed Debt or
to foreclose, take, or prosecute any action in connection with any Loan
Document; (h) any failure of Administrative Agent or any Lender to notify
Guarantor of any renewal, extension, or assignment of any Guaranteed Debt, or
the release of any security or of any other action taken or refrained from being
taken by Administrative Agent or any Lender against Borrower or any new
agreement between Administrative Agent, any Lender, and Borrower; it being
understood that neither Administrative Agent nor any Lender is required to give
Guarantor any notice of any kind under any circumstances whatsoever with respect
to or in connection with any Guaranteed Debt, other than any notice required to
be given to Guarantor by Law or elsewhere in this Guaranty; (i) the
unenforceability of any Guaranteed Debt against any other obligor or any
security securing same because it exceeds the amount permitted by Law, the act
of creating it is ultra vires, the officers creating it exceeded their authority
or violated their fiduciary duties in connection with it, or otherwise; or (j)
any payment of the Obligation to Administrative Agent or any Lender is held to
constitute a preference under any Debtor Relief

<PAGE>

Law or for any other reason Administrative Agent or any Lender is required to
refund that payment or make payment to someone else (and in each such instance
this Guaranty will be reinstated in an amount equal to that payment).

      90 WAIVERS. By execution hereof, Guarantor acknowledges and agrees to the
waivers set forth in Section 11.2 of the Credit Agreement. To the maximum extent
lawful, Guarantor waives all Rights by which it might be entitled to require
suit on an accrued right of action in respect of any Guaranteed Debt or require
suit against Borrower or others.

      100 LOAN DOCUMENTS. By execution hereof, Guarantor covenants and agrees
that certain representations, warranties, terms, covenants, and conditions set
forth in the Loan Documents are applicable to Guarantor and shall be imposed
upon Guarantor, and Guarantor reaffirms that each such representation and
warranty is true and correct and covenants and agrees to promptly and properly
perform, observe, and comply with each such term, covenant, or condition.
Moreover, Guarantor acknowledges and agrees that this Guaranty is subject to the
offset provisions of the Loan Documents in favor of Administrative Agent and
Lenders. In the event the Credit Agreement or any other Loan Document shall
cease to remain in effect for any reason whatsoever during any period when any
part of the Guaranteed Debt remains unpaid, the terms, covenants, and agreements
of the Credit Agreement or such other Loan Document incorporated herein by
reference shall nevertheless continue in full force and effect as obligations of
Guarantor under this Guaranty.

      110 RELIANCE AND DUTY TO REMAIN INFORMED. Guarantor confirms that it has
executed and delivered this Guaranty after reviewing the terms and conditions of
the Loan Documents and such other information as it has deemed appropriate in
order to make its own credit analysis and decision to execute and deliver this
Guaranty. Guarantor confirms that it has made its own independent investigation
with respect to Borrower's creditworthiness and is not executing and delivering
this Guaranty in reliance on any representation or warranty by Administrative
Agent or any Lender as to that creditworthiness. Guarantor expressly assumes all
responsibilities to remain informed of the financial condition of Borrower and
any circumstances affecting Borrower's ability to perform under the Loan
Documents to which it is a party or any Collateral securing any Guaranteed Debt.

      120 NO REDUCTION. The Guaranteed Debt may not be reduced, discharged, or
released because or by reason of any existing or future offset, claim, or
defense (except for the defense of complete and final payment of the Guaranteed
Debt) of Borrower or any other obligor against Administrative Agent or any
Lender or against payment of the Guaranteed Debt, whether that offset, claim, or
defense arises in connection with the Guaranteed Debt or otherwise. Those claims
and defenses include, without limitation, failure of consideration, breach of
warranty, fraud, bankruptcy, incapacity/infancy, statute of limitations, lender
liability, accord and satisfaction, usury, forged signatures, mistake,
impossibility, frustration of purpose, and unconscionability.

      130 COMMUNICATIONS ACT. Notwithstanding any other provision of this
Guaranty, any action taken or proposed to be taken by Administrative Agent or
any Lender under this Guaranty which would affect the operational, voting, or
other control of Borrower or Guarantor, shall be pursuant to Section 310(d) of
the Communications Act of 1934 (as amended), applicable state Law, and the
applicable rules and regulations thereunder, and, if and to the extent required
thereby, subject to the prior consent of the FCC or any applicable PUC.

      140 INSOLVENCY OF GUARANTOR. Should Guarantor become insolvent, or fail to
pay Guarantor's debts generally as they become due, or voluntarily seek, consent
to, or acquiesce in, the benefit or benefits of any Debtor Relief Law (other
than as a creditor or claimant), or become a party to (or be made the subject
of) any proceeding provided for by any Debtor Relief Law (other than as a
creditor or claimant) that could suspend or otherwise adversely affect the
Rights of Administrative Agent or any Lender granted

<PAGE>

hereunder, then, in any such event, the Guaranteed Debt shall be, as among
Guarantor, Administrative Agent and Lenders, a fully matured, due, and payable
obligation of Guarantor to Administrative Agent and Lenders (without regard to
whether Borrower is then in default under the Loan Documents or whether the
Obligation, or any part thereof, is then due and owing by Borrower to any
Lender), payable in full by Guarantor to Lenders upon demand, and the amount
thereof so payable shall be the estimated amount owing in respect of the
contingent claim created hereunder.

      150 LOAN DOCUMENT. This Guaranty is a Loan Document and is subject to the
applicable provisions of Sections 1 and 13 of the Credit Agreement, including,
without limitation, the provisions relating to GOVERNING LAW, JURISDICTION,
VENUE, SERVICE OF PROCESS, AND WAIVER OF JURY TRIAL, all of which are
incorporated into this Guaranty by reference the same as if set forth in this
Guaranty verbatim.

      160 NOTICES. For purposes of Section 13.3 of the Credit Agreement,
Guarantor's address and telecopy number are as set forth next to Guarantor's
signature on the signature page hereof.

      170 AMENDMENTS, ETC. No amendment, waiver, or discharge to or under this
Guaranty is valid unless it is in writing and is signed by the party against
whom it is sought to be enforced and is otherwise in conformity with the
requirements of Section 13.11 of the Credit Agreement.

      180 ADMINISTRATIVE AGENT AND LENDERS. Administrative Agent is
Administrative Agent for each Lender under the Credit Agreement. All Rights
granted to Administrative Agent under or in connection with this Guaranty are
for each Lender's ratable benefit. Administrative Agent may, without the joinder
of any Lender, exercise any Rights in Administrative Agent's or Lenders' favor
under or in connection with this Guaranty. Administrative Agent's and each
Lender's Rights and obligations vis-a-vis each other may be subject to one or
more separate agreements between those parties. However, Guarantor is not
required to inquire about any such agreement or is subject to any terms of it
unless Guarantor specifically joins such agreement. Therefore, neither Guarantor
nor its successors or assigns is entitled to any benefits or provisions of any
such separate agreement or is entitled to rely upon or raise as a defense any
party's failure or refusal to comply with the provisions of such agreement.

      190 PARTIES. This Guaranty benefits Administrative Agent, Lenders, and
their respective successors and assigns and binds Guarantor and its successors
and assigns. Upon appointment of any successor Administrative Agent under the
Credit Agreement, all of the Rights of Administrative Agent under this Guaranty
automatically vest in that new Administrative Agent as successor Administrative
Agent on behalf of Lenders without any further act, deed, conveyance, or other
formality other than that appointment. The Rights of Administrative Agent and
Lenders under this Guaranty may be transferred with any assignment of the
Guaranteed Debt. The Credit Agreement contains provisions governing assignments
of the Guaranteed Debt and of Rights and obligations under this Guaranty.

      [20. [Included for Existing Guarantors] NO NOVATION. This Guaranty amends
and entirely restates the Existing Guaranty executed by Guarantor; provided,
however, that the execution and delivery of this Guaranty and the other Loan
Documents shall not in any circumstances be deemed to have terminated,
extinguished, or discharged the obligations and expenses under the Existing
Guaranty or the collateral security therefor, all of which shall continue under
and be governed by this Guaranty and the other Loan Documents.]

                   FORM OF AMENDED, RESTATED, AND CONSOLIDATED
                   PLEDGE, ASSIGNMENT, AND SECURITY AGREEMENT

      THIS AMENDED, RESTATED, AND CONSOLIDATED PLEDGE, ASSIGNMENT, AND SECURITY

                                    RECITALS

      A. Dobson Operating Co., L.L.C. (successor by merger with Dobson Operating
Company and Dobson Cellular Operations Company, "Borrower") has entered into an
Amended, Restated, and Consolidated Revolving Credit and Term Loan Agreement (as
amended, modified, supplemented, or restated from time to time, the "Credit
Agreement") dated as of January 18, 2000, with Bank of America, N.A., as
Administrative Agent (including its permitted successors and assigns in such
capacity, the "Administrative Agent"), and the Lenders now or hereafter party to
the Credit Agreement (including their respective permitted successors and
assigns, the "Lenders"), which Credit Agreement amends, restates, and
consolidates the Existing Credit Agreements (as such term is described and
defined in the Credit Agreement).

      B. To assure payment and performance of the Obligation under the Existing
DOC Credit Agreements, certain entities executed Security Agreements (including
without limitation, the agreements on Part A of Schedule 1, the "Existing DOC
Security Agreements").

      C. To assure payment and performance of the Obligation under the Existing
DCOC Credit Agreements, certain entities executed Security Agreements (including
without limitation, the agreements on Part B of Schedule 1, the "Existing DCOC
Security Agreements").

      D. In connection with the execution of and as a condition of the
effectiveness of, the Credit Agreement, the Existing DOC Security Agreements and
the Existing DCOC Security Agreements are required to be (and are hereby)
amended, restated, and consolidated in their entirety.

      E. This Security Agreement is integral to the transactions contemplated by
the Loan Documents, and the execution and delivery thereof, is a condition
precedent to Lenders' obligations to extend credit under the Loan Documents.

      ACCORDINGLY, for valuable consideration, the receipt and adequacy of which
are hereby acknowledged, Debtor and Secured Party hereby agree as follows:

      1 REFERENCE TO CREDIT AGREEMENT. The terms, conditions, and provisions of
the Credit Agreement are incorporated herein by reference, the same as if set
forth herein verbatim, which terms, conditions, and provisions shall continue to
be in full force and effect hereunder so long as Lenders are obligated to lend
under the Credit Agreement and thereafter until the Obligation is paid and
performed in full.

      2 CERTAIN DEFINITIONS. Unless otherwise defined herein, or the context
hereof otherwise requires, each term defined in either of the Credit Agreement
or in the UCC is used in this Security Agreement with the same meaning; provided
that, if the definition given to such term in the Credit Agreement

<PAGE>

conflicts with the definition given to such term in the UCC, the Credit
Agreement definition shall control to the extent legally allowable; and if any
definition given to such term in Chapter 9 of the UCC conflicts with the
definition given to such term in any other chapter of the UCC, the Chapter 9
definition shall prevail. As used herein, the following terms have the meanings
indicated:

            Collateral has the meaning set forth in Paragraph 4 hereof.

            FCC Licenses means all Authorizations, licenses, and permits issued
      by the FCC to Debtor.

            Lender means, individually, or Lenders means, collectively, on any
      date of determination, Administrative Agent and Lenders and their
      permitted successors and assigns.

            Obligation means, collectively, (a) the "Obligation" as defined in
      the Credit Agreement, and (b) all indebtedness, liabilities, and
      obligations of Debtor arising under this Security Agreement or Guaranty
      assuring payment of the Obligation; it being the intention and
      contemplation of Debtor and Secured Party that future advances will be
      made by Secured Party or one or more Lenders to Debtor for a variety of
      purposes, that Debtor may guarantee (or otherwise become directly or
      contingently obligated with respect to) the obligations of others to
      Secured Party or to one or more Lenders, that from time to time overdrafts
      of Debtor's accounts with Secured Party or with other Lenders may occur,
      and that Secured Party or one or more Lenders may from time to time
      acquire from others obligations of Debtor to such others, and that payment
      and repayment of all of the foregoing are intended to and shall be part of
      the Obligation secured hereby. The Obligation shall include, without
      limitation, future, as well as existing, advances, indebtedness,
      liabilities, and obligations owed by Debtor to Secured Party or to any
      Lender arising under the Loan Documents or otherwise.

            Obligor means any Person obligated with respect to any of the
      Collateral, whether as an account debtor, obligor on an instrument, issuer
      of securities, or otherwise.

            Partnership means any partnership issuing a Partnership Interest.

            Pledged Securities means, collectively, the Pledged Shares, the
      Partnership Interests (whether or not a security), and any other
      Collateral constituting securities.

            Security Interest means the security interest granted and the pledge
      and assignment made under Paragraph 3 hereof.

            UCC means the Uniform Commercial Code, including each such provision
      as it may subsequently be renumbered, as enacted in the State of New York
      or other applicable jurisdiction, as amended at the time in question.

      3 SECURITY INTEREST. In order to secure the full and complete payment and
performance of the Obligation when due, Debtor hereby grants to Secured Party a
Security Interest in all of Debtor's Rights, titles, and interests in and to the
Collateral and pledges, collaterally transfers, and assigns the Collateral to
Secured Party, all upon and subject to the terms and conditions of this Security
Agreement. Such Security Interest is granted and pledge and assignment are made
as security only and shall not subject Secured Party to, or transfer or in any
way affect or modify, any obligation of Debtor with respect to any of the
Collateral or any transaction involving or giving rise thereto. The grant
contained herein is intended to confer upon Secured Party all Rights that a
secured creditor may obtain and that may be granted in the FCC Licenses under
applicable Law as from time to time in effect. If the Law is subsequently
changed or clarified, or if the FCC's interpretation of existing Law is changed,
to permit or further permit the granting

<PAGE>

of such security interests in FCC Licenses, then Debtor's FCC Licenses, whether
now held or hereinafter acquired, shall automatically become subject to the
Secured Party's Security Interest to the maximum extent permitted by the Law as
then in effect. In the meantime, the value of the Systems' and Debtor's cellular
telephone communication businesses as a going concern depends upon the holder of
Debtor's FCC Licenses also being the owner of the assets used or useful in the
operation of the Systems and, if ownership of those assets is separated from the
FCC Licenses, the FCC might, under currently applicable Law, cancel the FCC
Licenses. Accordingly, Debtor and Secured Party, in recognition of the unique
nature of the FCC Licenses and the fact that the separation of the FCC Licenses
from Debtor's operating assets may prevent Lenders from adequately realizing the
value of their Security Interests, have provided in Paragraph 9(b) hereof for
the appointment of a receiver upon a Default or Potential Default and for the
assignment of the FCC Licenses in the event of the foreclosure hereunder, with
the specific intention in each case that the physical assets used in connection
with the Systems not be separated from the FCC Licenses. If the grant, pledge,
or collateral transfer or assignment of any specific item of the Collateral is
expressly prohibited by any contract, then the Security Interest created hereby
nonetheless remains effective to the extent allowed by UCC ss. 9.318 or other
applicable Law, but is otherwise limited by that prohibition.

      4 COLLATERAL. As used herein, the term "Collateral" means the following
items and types of property now owned or in the future acquired by Debtor:

            (a) All present and future accounts, contract Rights, general
      intangibles, chattel paper, documents, instruments, inventory, investment

      other investment securities issued by any Unrestricted Subsidiary of
      Debtor) now owned or hereafter acquired by Debtor, including, without
      limitation, all capital stock of the Domestic Subsidiaries of Debtor as
      more particularly listed on Annex B hereto, together with all
      Distributions with respect thereto or other property in exchange therefor,

            (c) Sixty-five percent (65%) of all present and future issued and
      outstanding stock, equity, membership interests, limited liability company
      interests, or other investment securities of each directly-owned Foreign
      Subsidiary now owned or hereafter acquired by such Debtor, including,
      without limitation, all capital stock of the directly-owned Foreign

            (d) All Rights, titles, and interests of such Debtor in and to all
      promissory notes and other instruments payable to such Debtor, now or
      hereafter existing, including, without limitation, all Cellular

<PAGE>

      documents assuring or securing payment of or otherwise evidencing the
      Collateral Notes as listed on Annex B (the "Collateral Note Security") in,
      to, and under all other loan and collateral documents relating to such
      instruments.

            (e) All present and future Rights, titles, interests, and Liens (but

      owned or hereafter acquired by such Debtor (collectively, the "Vehicles").

            (j) All present and future Rights, awards, and judgments to which
      such Debtor is entitled under any Litigation (whether arising in equity,
      contract, or tort) now existing or hereafter arising.

            (k) All present and future Rights (including, without limitation,
      the Right to sue for past, present, or future infringements), titles, and

      business identifiers, copyrights, designs, Rights or licenses to use any

            (l) All present and future Rights (including, without limitation,

            (m) All Authorizations, licenses, and permits issued by the FCC or
      any PUC, to the extent that the grant of a security interest in any such
      license or permit does not result in the

<PAGE>

      forfeiture of, or default under, any such license or permit, and the Right
      of Debtor to apply to the FCC for approval of transfers of licenses issued
      by the FCC.

            (n) All proceeds of any sale or other disposition of any
      Authorization, license, or permit issued by the FCC or any PUC, whether or
      not any such license or permit may lawfully be included as Collateral and
      whether or not the grant of a security interest in any such Authorization,
      license, or permit is otherwise prohibited.

            (o) All present and future increases, profits, combinations,
      reclassifications, improvements, and products of, accessions, attachments,
      and other additions to, tools, parts, and equipment used in connection

      heretofore described.

            (p) All present and future accounts, contract Rights, general
      intangibles, chattel paper, documents, instruments, cash and noncash
      proceeds, and other Rights arising from or by virtue of, or from the
      voluntary or involuntary sale or other disposition of, or collections with
      respect to, or insurance proceeds payable with respect to, or proceeds
      payable by virtue of warranty or other claims against the manufacturer of,
      or claims against any other Person with respect to, all or any part of the
      Collateral heretofore described in this clause or otherwise.

            (q) All present and future security for the payment to any Loan
      Party of any of the Collateral heretofore described and goods which gave
      or will give rise to any of such Collateral or are evidenced, identified,
      or represented therein or thereby.

Notwithstanding the foregoing, the Collateral shall not include (i) leases with
third parties for retail space or (ii) cellular transmission towers. [The
description of the Collateral contained in this Paragraph 4 shall not be deemed
to permit any action prohibited by this Security Agreement or by the terms
incorporated in this Security Agreement. Furthermore, notwithstanding any
contrary provision, Debtor agrees that, if, but for the application of this
paragraph, granting a Security Interest in the Collateral would constitute a
fraudulent conveyance under 11 U.S.C. ss. 548 or a fraudulent conveyance or
transfer under any state fraudulent conveyance, fraudulent transfer, or similar
Law in effect from time to time (each a "fraudulent conveyance"), then the
Security Interest remains enforceable to the maximum extent possible without
causing such Security Interest to be a fraudulent conveyance, and this Security
Agreement is automatically amended to carry out the intent of this paragraph.]
[Bracketed language to be included in all Security Agreements other than the
Security Agreement for Borrower.]

      5. REPRESENTATIONS AND WARRANTIES. Debtor represents and warrants to
Secured Party that:

            (a) Credit Agreement. Certain representations and warranties in the
      Credit Agreement are applicable to it or its assets or operations, and
      each such representation and warranty is true and correct.

            (b) Binding Obligation. This Security Agreement creates a legal,
      valid, and binding Lien in and to the Collateral in favor of Secured Party
      and enforceable against Debtor. For Collateral in which the Security
      Interest may be perfected by the filing of Financing Statements, once
      those Financing Statements have been properly filed in the jurisdictions
      described on Annex A hereto, the Security Interest in that Collateral will
      be fully perfected. Once perfected and, in the case of investment property
      or instruments, upon possession or "control" (within the meaning of
      Sections 8-106 and 9-115 of the UCC) by Secured Party, the Security
      Interest will constitute a first-priority Lien

<PAGE>

      on the Collateral, subject only to Permitted Liens. The creation of the
      Security Interest does not require the consent of any Person that has not
      been obtained.

            (c) Location. Debtor's place of business and chief executive office
      is where Debtor is entitled to receive notices hereunder; the present and
      foreseeable location of Debtor's books and records concerning any of the
      Collateral that is accounts is as set forth on Annex A hereto, and the
      location of all other Collateral, including, without limitation, Debtor's
      inventory and equipment, but excluding cellular transmission towers, is as
      set forth on Annex A hereto (but the failure of such description to be
      accurate or complete shall not impair the Security Interest in such
      Collateral); and, except as noted on Annex A hereto, all such books,
      records, and Collateral are in Debtor's possession.

            (d) Fixtures. The Collateral that is or may be fixtures is located
      on or affixed to the real property described on Annex A hereto (but the
      failure of such description to be accurate or complete shall not impair
      the Security Interest in such Collateral).

            (e) Securities. All Collateral that is Pledged Securities is duly
      authorized, validly issued, fully paid, and non-assessable, and the
      transfer thereof is not subject to any restrictions, other than
      restrictions imposed by applicable securities and corporate Laws. The
      Pledged Shares constitute 100% of the issued and outstanding common stock
      or other equity interests of each Domestic Subsidiary owned by Debtor and
      65% of the issued and outstanding common stock or other equity interest of
      each Foreign Subsidiary owned directly by Debtor, other than the common
      stock or other equity interests of any Domestic Subsidiary that is an
      Unrestricted Subsidiary of Debtor. Debtor has good title to the
      securities, free and clear of all Liens and encumbrances thereon (except
      for the Security Interest created hereby), and has delivered to Secured
      Party all stock certificates, promissory notes, bonds, debentures, or
      other instruments or documents representing or evidencing the securities,
      together with corresponding assignment or transfer powers duly executed in
      blank by Debtor, and such powers have been duly and validly executed and
      are binding and enforceable against Debtor in accordance with their terms;
      and the pledge of the securities in accordance with the terms hereof
      creates a valid and perfected first priority security interest in the
      securities securing payment of the Obligation.

            (f) Partnerships and Partnership Interests. Each Partnership issuing
      a Partnership Interest, including, without limitation, any Cellular
      Partnership, is duly organized, currently existing, and in good standing
      under all applicable Laws; there have been no amendments, modifications,
      or supplements to any agreement or certificate creating any Partnership or
      any material contract relating to the Partnerships, of which Secured Party
      has not been advised in writing; no default or potential default has
      occurred under the terms of any material contract relating to any
      Partnership; and no approval or consent of the partners of any Partnership
      is required as a condition to the validity and enforceability of the
      Security Interest created hereby or the consummation of the transactions
      contemplated hereby which has not been duly obtained by Debtor. Debtor has
      good title to the Partnership Interests free and clear of all Liens and
      encumbrances (except for the Security Interest granted hereby). The
      Partnership Interests are validly issued, fully paid, and nonassessable
      and are not subject to statutory, contractual, or other restrictions
      governing their transfer, ownership, or control, except as set forth in
      the partnership agreements of the Cellular Partnerships or applicable
      securities Laws.

            (g) Governmental Authority. No authorization, approval, or other
      action by, and no notice to or filing with, any Governmental Authority is
      required either (i) for the pledge by Debtor of the Collateral pursuant to
      this Security Agreement or for the execution, delivery, or performance

<PAGE>

      of this Security Agreement by Debtor, or (ii) for the exercise by Secured
      Party of the voting or other Rights provided for in this Security
      Agreement or the remedies in respect of the Collateral pursuant to this
      Security Agreement (except as may be required in connection with the
      disposition of the Pledged Securities by Laws affecting the offering and
      sale of securities generally and in connection with the transfer of
      control of FCC Licenses).

            (h) Accounts. All Collateral that is accounts, contract Rights,
      chattel paper, instruments, or general intangibles is free from any claim
      for credit, deduction, or allowance of an Obligor and free from any
      defense, dispute, setoff, or counterclaim, and there is no extension or
      indulgence with respect thereto.

            (i) Instruments, Chattel Paper, Collateral Notes, and Collateral
      Note Security. All instruments and chattel paper, including, without
      limitation, the Collateral Notes, have been delivered to Secured Party,
      together with corresponding endorsements duly executed by Debtor in favor
      of Secured Party, and such endorsements have been duly and validly
      executed and are binding and enforceable against Debtor in accordance with
      their terms. Each Collateral Note and the documents evidencing the
      Collateral Note Security are in full force and effect; there have been no
      renewals or extensions of, or amendments, modifications, or supplements
      to, any thereof about which the Secured Party has not been advised in
      writing; and no default or potential default has occurred and is
      continuing under any such Collateral Note or documents evidencing the
      Collateral Note Security, except as disclosed on Annex C hereto.

            (j) Assigned Leases. All Collateral that is an Assigned Lease is in
      full force and effect; Debtor is in possession of the property covered by
      each such Assigned Lease; and no default or potential default exists under
      any such Assigned Lease.

            (k) Maintenance of Collateral. All tangible Collateral which are
      useful in and necessary to Debtor's business is in good repair and
      condition, ordinary wear and tear excepted, and none thereof is a fixture
      except as specifically referred to herein in Paragraph 5(d) hereof.

            (l) Liens. Debtor owns all presently existing Collateral, and will
      acquire all hereafter-acquired Collateral, free and clear of all Liens,
      except Permitted Liens.

            (m) Deposit Accounts. With respect to the material Deposit Accounts,
      (i) Debtor maintains each such Deposit Account with the banks listed on
      Annex D hereto, (ii) Debtor shall use its best efforts to, within thirty
      (30) days of the Closing Date, cause each such bank to acknowledge to
      Secured Party that each such Deposit Account is subject to the Security
      Interest and Liens herein created, (iii) Debtor has the legal Right to
      pledge and assign to Secured Party the funds deposited and to be deposited
      in each such Deposit Account; and (iv) the Deposit Accounts listed on
      Annex D represent all material bank accounts of Debtor, including without
      limitation, all material operating accounts of Debtor, and all
      certificates of deposit or other deposit instruments of Debtor.

The foregoing representations and warranties will be true and correct in all
respects with respect to any additional Collateral or additional specific
descriptions of certain Collateral delivered to Secured Party in the future by
Debtor.

      The failure of any of these representations or warranties to be accurate
and complete does not impair the Security Interest in any Collateral.

<PAGE>

      6. COVENANTS. So long as Lenders are committed to extend credit to
Borrower or Debtor under the Credit Agreement and until the Obligation is paid
and performed in full, Debtor covenants and agrees with Secured Party that
Debtor will:

            (a) Credit Agreement. (i) Comply with, perform, and be bound by all
      covenants and agreements in the Credit Agreement that are applicable to
      it, its assets, or its operations, each of which is hereby ratified and
      confirmed (INCLUDING, WITHOUT LIMITATION, THE INDEMNIFICATION AND RELATED
      PROVISIONS IN SECTION 11.12 OF THE CREDIT AGREEMENT); AND (ii) CONSENT TO
      AND APPROVE THE VENUE, SERVICE OF PROCESS, AND WAIVER OF JURY TRIAL
      PROVISIONS OF SECTION 13.10 OF THE CREDIT AGREEMENT.

            (b) Record of Collateral. Maintain, at the place where Debtor is
      entitled to receive notices under the Loan Documents, a current record of
      where all Collateral is located, permit representatives of Secured Party
      at any time during normal business hours to inspect and make abstracts
      from such records, and furnish to Secured Party, at such intervals as
      Secured Party may request, such documents, lists, descriptions,
      certificates, and other information as may be necessary or proper to keep
      Secured Party informed with respect to the identity, location, status,
      condition, and value of the Collateral.

            (c) Perform Obligations. Fully perform all of Debtor's duties under
      and in connection with each transaction to which the Collateral, or any
      part thereof, relates, so that the amounts thereof shall actually become
      payable in their entirety to Secured Party.

            (d) Notices. (i) Promptly notify Secured Party of (A) any change in
      any fact or circumstances represented or warranted by Debtor with respect
      to any of the Collateral or Obligation, (B) any claim, action, or
      proceeding affecting title to all or any of the Collateral or the Security
      Interest and, at the request of Secured Party, appear in and defend, at
      Debtor's expense, any such action or proceeding, (C) any material change
      in the nature of the Collateral, (D) any material damage to or loss of
      Collateral, and (E) the occurrence of any other event or condition
      (including without limitation matters as to Lien priority) that could have
      a material adverse effect on the Collateral (taken as a whole) or the
      Security Interest created hereunder; and (ii) give Secured Party thirty
      (30) days written notice before any proposed (A) relocation of its
      principal place of business or chief executive office, (B) change of its
      name, identity, or corporate structure, (C) relocation of the place where
      its books and records concerning its accounts are kept, and (D) relocation
      of any Collateral (other than delivery of inventory in the ordinary course
      of business to third party contractors for processing and sales of
      inventory in the ordinary course of business or as permitted by the Credit
      Agreement) to a location not described on the attached Annex A. Prior to
      making any of the changes contemplated in clause (ii) preceding, Debtor
      shall execute and deliver all such additional documents and perform all
      additional acts as Secured Party, in its sole discretion, may request in
      order to continue or maintain the existence and priority of the Security
      Interests in all of the Collateral.

            (e) Collateral in Trust. Hold in trust (and not commingle with other
      assets of Debtor) for Secured Party all Collateral that is chattel paper,
      instruments, Collateral Notes, Pledged Securities, or documents at any
      time received by Debtor, and promptly deliver same to Secured Party,
      unless Secured Party at its option (which may be evidenced only by a
      writing signed by Secured Party stating that Secured Party elects to
      permit Debtor to so retain) permits Debtor to retain the same, but any
      chattel paper, instruments, Collateral Notes, or documents so retained
      shall be marked to state that they are assigned to Secured Party; each
      such instrument shall be endorsed to

<PAGE>

      the order of Secured Party (but the failure of same to be so marked or
      endorsed shall not impair the Security Interest thereon).

            (f) Further Assurances. At Debtor's expense and Secured Party's
      request, before or after a Default or Potential Default, (i) file or cause
      to be filed such applications and take such other actions as Secured Party
      may request to obtain the consent or approval of any Governmental
      Authority to Secured Party's Rights hereunder, including, without
      limitation, the Right to sell all the Collateral upon a Default or
      Potential Default without additional consent or approval from such
      Governmental Authority (and, because Debtor agrees that Secured Party's
      remedies at Law for failure of Debtor to comply with this provision would
      be inadequate and that such failure would not be adequately compensable in
      damages, Debtor agrees that its covenants in this provision may be
      specifically enforced); (ii) from time to time promptly execute and
      deliver to Secured Party all such other assignments, certificates,
      supplemental documents, and financing statements, and do all other acts or
      things as Secured Party may reasonably request in order to more fully
      create, evidence, perfect, continue, and preserve the priority of the
      Security Interest and to carry out the provisions of the Security
      Agreement; and (iii) pay all filing fees in connection with any financing,
      continuation, or termination statement or other instrument with respect to
      the Security Interests, including, without limitation, any filing fee
      required in connection with any procedure hereafter developed for the
      recordation or registration of Liens or security interests in FCC
      Licenses.

            (g) Fixtures. For any Collateral that is a fixture or an accession
      which has been attached to real estate or other goods prior to the
      perfection of the Security Interest, furnish Secured Party, upon
      reasonable demand, a disclaimer of interest in each such fixture or
      accession and a consent in writing to the Security Interest of Secured
      Party therein, signed by all Persons having any interest in such fixture
      or accession by virtue of any interest in the real estate or other goods
      to which such fixture or accession has been attached.

            (h) Encumbrances. Debtor shall not create, permit, or suffer to
      exist, and shall defend the Collateral against, any Lien or other
      encumbrance on the Collateral, and shall defend Debtor's Rights in the
      Collateral and Secured Party's Security Interest in, the Collateral
      against the claims and demands of all Persons except those holding or
      claiming Permitted Liens. Debtor shall do nothing to impair the Rights of
      the Secured Party in the Collateral.

            (i) Estoppel and Other Agreements and Matters. Upon the reasonable
      request of Administrative Agent, either (i) use commercially reasonable
      efforts to cause the landlord or lessor for each location where any of its
      inventory or equipment is maintained to execute and deliver to Secured
      Party an estoppel and subordination agreement in such form as may be
      reasonably acceptable to Secured Party and its counsel, or (ii) deliver to
      Secured Party a legal opinion or other evidence (in each case that is
      reasonably satisfactory to Secured Party and it counsel) that neither the
      applicable lease nor the Laws of the jurisdiction in which that location
      is situated provide for contractual, common law, or statutory landlord's
      Liens that is senior to or pari passu with the Security Interest.

            (j) Certificates of Title. Upon the request of Secured Party, if
      certificates of title are issued or outstanding with respect to any of the
      Vehicles or other Collateral, cause the Security Interest to be properly
      noted thereon.

            (k) Impairment of Collateral. Not use any of the Collateral, or
      permit the same to be used, for any unlawful purpose, in any manner that
      is reasonably likely to adversely impair the value or usefulness of the
      Collateral, or in any manner inconsistent with the provisions or
      requirements of

<PAGE>

      any policy of insurance thereon nor affix or install any accessories,
      equipment, or device on the Collateral or on any component thereof if such
      addition will impair the original intended function or use of the
      Collateral or such component.

            (l) Modifications to Agreements. Not modify or substitute, or permit
      the modification or substitution of, any Collateral Note or any document
      evidencing the Collateral Note Security or contract to which any of the
      Collateral which is accounts relates, nor extend or grant indulgences
      regarding any account which is Collateral, other than such modifications
      or indulgences as are reasonable and customary in the industry in which
      Debtor is engaged.

            (m) Securities. Except as permitted by the Credit Agreement, not
      sell, exchange, or otherwise dispose of, or grant any option, warrant, or
      other Right with respect to, any of the Pledged Shares; not permit any
      issuer of any Pledged Shares to issue any additional shares of stock or
      other securities in addition to or in substitution for the Pledged Shares,
      except issuances to Debtor on terms acceptable to Secured Party; cause any

      Debtor; and take any action necessary, required, or requested by Secured
      Party to allow Secured Party to fully enforce its Security Interest in the
      Pledged Shares, including, without limitation, the filing of any claims
      with any court, liquidator, trustee, custodian, receiver, or other like
      person or party.

            (n) Partnerships and Partnership Interests. (i) Promptly perform,
      observe, and otherwise comply with each and every covenant, agreement,
      requirement, and condition set forth in the contracts and agreements
      creating or relating to any Partnership; (ii) do or cause to be done all
      things necessary or appropriate to keep the Partnerships in full force and
      effect and the Rights of Debtor and Secured Party thereunder unimpaired;
      (iii) not consent to any Partnership selling, leasing, or disposing of
      substantially all of its assets in a single transaction or a series of
      transactions; (iv) notify Secured Party of the occurrence of any default
      under any contract or agreement creating or relating to the Partnerships;
      (v) not consent to the amendment, modification, surrender, impairment,

      Debtor; (viii) pledge hereunder, immediately upon Debtor's acquisition
      (directly or indirectly) thereof, any and all additional Partnership

      a fully-executed Pledge Instruction, substantially in the form of Annex F,
      for each Partnership Interest, together with the General Partner's written
      consent thereto and an Initial Transaction Statement executed by the
      Managing General Partner of such Partnership; and (x) take any action
      necessary, required, or requested by Secured Party to allow Secured Party
      to fully enforce its Security Interest in the Partnership Interests,
      including, without limitation, the filing of any claims with any court,
      liquidator, trustee, custodian, receiver, or other like person or party.

            (o) Depository Bank. With respect to any material Deposit Accounts,
      (i) maintain the Deposit Accounts at the banks (a "depository bank")
      described on Annex D or such additional depository banks as have complied

<PAGE>

Date, deliver to each depository bank a letter in the form of Annex E hereto
with respect to Secured Party's Rights in such Deposit Account and use its best

establishing any additional Deposit Accounts and, at the request of Secured
Party, obtain from such depository bank an executed letter substantially in the

            (p) Information. Debtor shall from time to time at the request of
      Secured Party deliver to the Secured Party such information regarding the
      Collateral and the Debtor as the Secured Party may reasonably request,
      including, without limitation, lists and descriptions of the Collateral
      and evidence of the identity and existence of the Collateral.

      7. DEFAULT; REMEDIES. If a Default or a Potential Default exists, Secured
Party may, at its election (but subject to the terms and conditions of the
Credit Agreement), exercise any and all Rights available to a secured party
under the UCC, in addition to any and all other Rights afforded by the Loan
Documents, at Law, in equity, or otherwise, including, without limitation, (a)
requiring Debtor to assemble all or part of the Collateral and make it available
to Secured Party at a place to be designated by Secured Party which is
reasonably convenient to Debtor and Secured Party, (b) surrendering any policies
of insurance on all or part of the Collateral and receiving and applying the
unearned premiums as a credit on the Obligation, (c) applying by appropriate
judicial proceedings for appointment of a receiver for all or part of the
Collateral (and Debtor hereby consents to any such appointment), and (d)
applying to the Obligation any cash held by Secured Party under this Security
Agreement, including, without limitation, any cash in the Cash Collateral
Account (defined in Section 8(g)). Notwithstanding the foregoing, Secured Party
will not exercise any remedies against the assets of Debtor unless it has given
at least ten days written notification to Debtor and to the FCC, to the extent
such notice is required under 47 C.F.R. 22.937(f).

            (a) Notice. Reasonable notification of the time and place of any
      public sale of the Collateral, or reasonable notification of the time
      after which any private sale or other intended disposition of the
      Collateral is to be made, shall be sent to Debtor and to any other Person
      entitled to notice under the UCC; provided that, if any of the Collateral
      threatens to decline speedily in value or is of the type customarily sold
      on a recognized market, Secured Party may sell or otherwise dispose of the
      Collateral without notification, advertisement, or other notice of any
      kind. It is agreed that notice sent or given not less than ten Business
      Days prior to the taking of the action to which the notice relates is
      reasonable notification and notice for the purposes of this subparagraph.

            (b) Sales of Pledged Securities.

                  (i) Debtor agrees that, because of the Securities Act of 1933,
            as amended, or the rules and regulations promulgated thereunder
            (collectively, the "Securities Act"), or any other Laws or
            regulations, and for other reasons, there may be legal or practical
            restrictions or limitations affecting Secured Party in any attempts
            to dispose of certain portions of the Pledged Securities and for the
            enforcement of its Rights. For these reasons, Secured Party is
            hereby authorized by Debtor, but not obligated, upon the occurrence
            and during the continuation of a Default or Potential Default, to
            sell all or any part of the Pledged Securities at private sale,
            subject to investment letter or in any other manner which will not
            require the Pledged Securities, or any part thereof, to be
            registered in accordance with the Securities Act or any other Laws
            or regulations, at a reasonable price at such private sale or other
            distribution in the manner mentioned above. Debtor understands that
            Secured Party may in

<PAGE>

            its discretion approach a limited number of potential purchasers and
            that a sale under such circumstances may yield a lower price for the
            Pledged Securities, or any part thereof, than would otherwise be
            obtainable if such Collateral were either afforded to a larger
            number or potential purchasers, registered under the Securities Act,
            or sold in the open market. Debtor agrees that any such private sale
            made under this Paragraph 7(b) shall be deemed to have been made in
            a commercially reasonable manner, and that Secured Party has no
            obligation to delay the sale of any Pledged Securities to permit the
            issuer thereof to register it for public sale under any applicable
            federal or state securities Laws.

                  (ii) Secured Party is authorized, in connection with any such
            sale, (A) to restrict the prospective bidders on or purchasers of
            any of the Pledged Securities to a limited number of sophisticated
            investors who will represent and agree that they are purchasing for
            their own account for investment and not with a view to the
            distribution or sale of any of such Pledged Securities, and (B) to
            impose such other limitations or conditions in connection with any
            such sale as Secured Party reasonably deems necessary in order to
            comply with applicable Law. Debtor covenants and agrees that it will
            execute and deliver such documents and take such other action as
            Secured Party reasonably deems necessary in order that any such sale
            may be made in compliance with applicable Law. Upon any such sale
            Secured Party shall have the Right to deliver, assign, and transfer
            to the purchaser thereof the Pledged Securities so sold. Each
            purchaser at any such sale shall hold the Pledged Securities so sold
            absolutely free from any claim or Right of Debtor of whatsoever
            kind, including any equity or Right of redemption of Debtor. Debtor,
            to the extent permitted by applicable Law, hereby specifically
            waives all Rights of redemption, stay, or appraisal which it has or
            may have under any Law now existing or hereafter enacted.

                  (iii) Debtor agrees that five days' written notice from
            Secured Party to Debtor of Secured Party's intention to make any
            such public or private sale or sale at a broker's board or on a
            securities exchange shall constitute "reasonable notification"
            within the meaning of Section 9-504(c) of the UCC. Such notice shall
            (A) in case of a public sale, state the time and place fixed for
            such sale, (B) in case of sale at a broker's board or on a
            securities exchange, state the board or exchange at which such a
            sale is to be made and the day on which the Pledged Securities, or
            the portion thereof so being sold, will first be offered to sale at
            such board or exchange, and (C) in the case of a private sale, state
            the day after which such sale may be consummated. Any such public
            sale shall be held at such time or times within ordinary business
            hours and at such place or places as Secured Party may fix in the
            notice of such sale. At any such sale, the Pledged Securities may be
            sold in one lot as an entirety or in separate parcels, as Secured
            Party may reasonably determine. Secured Party shall not be obligated
            to make any such sale pursuant to any such notice. Secured Party
            may, without notice or publication, adjourn any public or private
            sale or cause the same to be adjourned from time to time by
            announcement at the time and place fixed for the sale, and such sale
            may be made at any time or place to which the same may be so
            adjourned.

                  (iv) In case of any sale of all or any part of the Pledged
            Securities on credit or for future delivery, the Pledged Securities
            so sold may be retained by Secured Party until the selling price is
            paid by the purchaser thereof, but Secured Party shall not incur any
            liability in case of the failure of such purchaser to take up and
            pay for the Pledged Securities so sold and in case of any such
            failure, such Pledged Securities may again be sold upon like notice.
            Secured Party, instead of exercising the power of sale herein
            conferred upon it, may proceed by a suit or suits at law or in
            equity to foreclose the Security Interests and sell the Pledged

<PAGE>

            Securities, or any portion thereof, under a judgment or decree of a
            court or courts of competent jurisdiction.

                  (v) Without limiting the foregoing, or imposing upon Secured
            Party any obligations or duties not required by applicable Law,
            Debtor acknowledges and agrees that, in foreclosing upon any of the
            Pledged Securities, or exercising any other Rights or remedies
            provided Secured Party hereunder or under applicable Law, Secured
            Party may, but shall not be required to, (A) qualify or restrict
            prospective purchasers of the Pledged Securities by requiring
            evidence of sophistication or creditworthiness, and requiring the
            execution and delivery of confidentiality agreements or other
            documents and agreements as a condition to such prospective
            purchasers' receipt of information regarding the Pledged Securities
            or participation in any public or private foreclosure sale process,
            (B) provide to prospective purchasers business and financial
            information regarding Debtor or the Companies available in the files
            of Secured Party at the time of commencing the foreclosure process,
            without the requirement that Secured Party obtain, or seek to
            obtain, any updated business or financial information or verify, or
            certify to prospective purchasers, the accuracy of any such business
            or financial information, or (C) offer for sale and sell the Pledged
            Securities with, or without, first employing an appraiser,
            investment banker, or broker with respect to the evaluation of the
            Pledged Securities, the solicitation of purchasers for Pledged
            Securities, or the manner of sale of Pledged Securities.

            (c) Application of Proceeds. Secured Party shall apply the proceeds
      of any sale or other disposition of the Collateral under this Paragraph 7
      in the following order: first, to the payment of all expenses incurred in
      retaking, holding, and preparing any of the Collateral for sale(s) or
      other disposition, in arranging for such sale(s) or other disposition, and
      in actually selling or disposing of the same (all of which are part of the
      Obligation); second, toward repayment of amounts expended by Secured Party
      under Paragraph 8; third, toward payment of the balance of the Obligation
      in the order and manner specified in the Credit Agreement. Any surplus
      remaining shall be delivered to Debtor or as a court of competent
      jurisdiction may direct. If the proceeds are insufficient to pay the
      Obligation in full, Debtor shall remain liable for any deficiency.

      8. OTHER RIGHTS OF SECURED PARTY.

            (a) Performance. If Debtor fails to keep the Collateral in good
      repair, working order, and condition, as required in this Security
      Agreement, or fails to pay when due all Taxes on any of the Collateral in
      the manner required by the Loan Documents, or fails to preserve the
      priority of the Security Interest in any of the Collateral, or fails to
      keep the Collateral insured as required by the Credit Agreement, or
      otherwise fails to perform any of its obligations under the Loan Documents
      with respect to the Collateral, then Secured Party may, at its option, but
      without being required to do so, make such repairs, pay such Taxes,
      prosecute or defend any suits in relation to the Collateral, or insure and
      keep insured the Collateral in any amount deemed appropriate by Secured
      Party, or take all other action which Debtor is required, but has failed
      or refused, to take under the Loan Documents. Any sum which may be
      expended or paid by Secured Party under this subparagraph (including,
      without limitation, court costs and attorneys' fees) shall bear interest
      from the dates of expenditure or payment at the Default Rate until paid
      and, together with such interest, shall be payable by Debtor to Secured
      Party upon demand and shall be part of the Obligation.

            (b) Collection. If a Default or Potential Default exists and upon
      notice from Secured Party, each Obligor with respect to any payments on
      any of the Collateral (including, without limitation, dividends and other
      distributions with respect to securities, payments on Collateral Notes,

<PAGE>

      insurance proceeds payable by reason of loss or damage to any of the
      Collateral, or Deposit Accounts) is hereby authorized and directed by
      Debtor to make payment directly to Secured Party, regardless of whether
      Debtor was previously making collections thereon. Subject to Paragraph
      8(e) hereof, until such notice is given, Debtor is authorized to retain
      and expend all payments made on Collateral. If a Default or Potential
      Default exists, Secured Party shall have the Right in its own name or in
      the name of Debtor to compromise or extend time of payment with respect to
      all or any portion of the Collateral for such amounts and upon such terms
      as Secured Party may determine; to demand, collect, receive, receipt for,
      sue for, compound, and give acquittances for any and all amounts due or to
      become due with respect to Collateral; to take control of cash and other
      proceeds of any Collateral; to endorse the name of Debtor on any notes,
      acceptances, checks, drafts, money orders, or other evidences of payment
      on Collateral that may come into the possession of Secured Party; to sign
      the name of Debtor on any invoice or bill of lading relating to any
      Collateral, on any drafts against Obligors or other Persons making payment
      with respect to Collateral, on assignments and verifications of accounts
      or other Collateral and on notices to Obligors making payment with respect
      to Collateral; to send requests for verification of obligations to any
      Obligor; and to do all other acts and things necessary to carry out the
      intent of this Security Agreement. If a Default or Potential Default
      exists and any Obligor fails or refuses to make payment on any Collateral
      when due, Secured Party is authorized, in its sole discretion, either in
      its own name or in the name of Debtor, to take such action as Secured
      Party shall deem appropriate for the collection of any amounts owed with
      respect to Collateral or upon which a delinquency exists. Regardless of
      any other provision hereof, however, Secured Party shall never be liable
      for its failure to collect, or for its failure to exercise diligence in
      the collection of, any amounts owed with respect to Collateral, nor shall
      it be under any duty whatsoever to anyone except Debtor to account for
      funds that it shall actually receive hereunder. Without limiting the
      generality of the foregoing, Secured Party shall have no responsibility
      for ascertaining any maturities, calls, conversions, exchanges, offers,
      tenders, or similar matters relating to any Collateral, or for informing
      Debtor with respect to any of such matters (irrespective of whether
      Secured Party actually has, or may be deemed to have, knowledge thereof).
      The receipt of Secured Party to any Obligor shall be a full and complete
      release, discharge, and acquittance to such Obligor, to the extent of any
      amount so paid to Secured Party.

            (c) Record Ownership of Securities. If a Default or Potential
      Default exists, Secured Party at any time may have any Collateral that is
      Pledged Securities and that is in the possession of Secured Party, or its
      nominee or nominees, registered in its name, or in the name of its nominee
      or nominees, as Secured Party; and, as to any Collateral that is Pledged
      Securities so registered, Secured Party shall execute and deliver (or
      cause to be executed and delivered) to Debtor all such proxies, powers of
      attorney, dividend coupons or orders, and other documents as Debtor may
      reasonably request for the purpose of enabling Debtor to exercise the
      voting Rights and powers which it is entitled to exercise under this
      Security Agreement or to receive the dividends and other Distributions and
      payments in respect of such Collateral that is Pledged Securities or
      proceeds thereof which it is authorized to receive and retain under this
      Security Agreement.

            (d) Voting of Securities. As long as no Default or Potential Default
      exists, Debtor is entitled to exercise all voting Rights pertaining to any
      Pledged Securities; provided, however, that no vote shall be cast or
      consent, waiver, or ratification given or action taken without the prior
      written consent of Secured Party which would (x) be inconsistent with or
      violate any provision of this Security Agreement or any other Loan
      Document or (y) amend, modify, or waive any term, provision or condition
      of the certificate of incorporation, bylaws, certificate of formation, or
      other charter document, or other agreement relating to, evidencing,
      providing for the issuance of, or securing any Collateral; and provided
      further that Debtor shall give Secured Party at least five Business Days'
      prior written notice in the form of an officers' certificate of the manner
      in which it intends to

<PAGE>

      exercise, or the reasons for refraining from exercising, any voting or
      other consensual Rights pertaining to the Collateral or any part thereof
      which might have a material adverse effect on the value of the Collateral
      or any part thereof. If a Default or Potential Default exists and if
      Secured Party elects to exercise such Right, the Right to vote any Pledged
      Securities shall be vested exclusively in Secured Party. To this end,
      Debtor hereby irrevocably constitutes and appoints Secured Party the proxy
      and attorney-in-fact of Debtor, with full power of substitution, to vote,
      and to act with respect to, any and all Collateral that is Pledged
      Securities standing in the name of Debtor or with respect to which Debtor
      is entitled to vote and act, subject to the understanding that such proxy
      may not be exercised unless a Default exists. The proxy herein granted is
      coupled with an interest, is irrevocable, and shall continue until the
      Obligation has been paid and performed in full.

            (e) Certain Proceeds. Notwithstanding any contrary provision herein,
      any and all

                  (i) dividends, interest, or other Distributions paid or
            payable other than in cash in respect of, and instruments and other
            property received, receivable, or otherwise distributed in respect
            of, or in exchange for, any Collateral;

                  (ii) dividends, interest, or other Distributions hereafter
            paid or payable in cash in respect of any Collateral in connection
            with a partial or total liquidation or dissolution, or in connection
            with a reduction of capital, capital surplus, or paid-in-surplus;

                  (iii) cash paid, payable, or otherwise distributed in
            redemption of, or in exchange for, any Collateral; and

                  (iv) dividends, interest, or other Distributions paid or
            payable in violation of the Loan Documents,

      shall be part of the Collateral hereunder, shall, if received by Debtor,
      be held in trust for the benefit of Secured Party, and shall forthwith be
      delivered to Secured Party (accompanied by proper instruments of
      assignment and/or stock and/or bond powers executed by Debtor in
      accordance with Secured Party's instructions) to be held subject to the
      terms of this Security Agreement. Any cash proceeds of Collateral which
      come into the possession of Secured Party (including, without limitation,
      insurance proceeds) may, at Secured Party's option, be applied in whole or
      in part to the Obligation (to the extent then due), be released in whole
      or in part to or on the written instructions of Debtor for any general or
      specific purpose, or be retained in whole or in part by Secured Party as
      additional Collateral. Any cash Collateral in the possession of Secured
      Party may be invested by Secured Party in certificates of deposit issued
      by Secured Party (if Secured Party issues such certificates) or by any
      state or national bank having combined capital and surplus greater than
      $100,000,000 with a rating from Moody's and S&P of P-1 and A-1+,
      respectively, or in securities issued or guaranteed by the United States
      of America or any agency thereof. Secured Party shall never be obligated
      to make any such investment and shall never have any liability to Debtor
      for any loss which may result therefrom. All interest and other amounts
      earned from any investment of Collateral may be dealt with by Secured
      Party in the same manner as other cash Collateral. The provisions of this
      subparagraph are applicable whether or not a Default or Potential Default
      exists.

            (f) Use and Operation of Collateral. Should any Collateral come into
      the possession of Secured Party, Secured Party may use or operate such
      Collateral for the purpose of preserving it or its value pursuant to the
      order of a court of appropriate jurisdiction or in accordance with any
      other Rights held by Secured Party in respect of such Collateral. Debtor
      covenants to promptly reimburse and pay to Secured Party, at Secured
      Party's request, the amount of all reasonable

<PAGE>

      expenses (including, without limitation, the cost of any insurance and
      payment of Taxes or other charges) incurred by Secured Party in connection
      with its custody and preservation of Collateral, and all such expenses,
      costs, Taxes, and other charges shall bear interest at the Default Rate
      until repaid and, together with such interest, shall be payable by Debtor
      to Secured Party upon demand and shall become part of the Obligation.
      However, the risk of accidental loss or damage to, or diminution in value
      of, Collateral is on Debtor, and Secured Party shall have no liability
      whatever for failure to obtain or maintain insurance, nor to determine
      whether any insurance ever in force is adequate as to amount or as to the
      risks insured. With respect to Collateral that is in the possession of
      Secured Party, Secured Party shall have no duty to fix or preserve Rights
      against prior parties to such Collateral and shall never be liable for any
      failure to use diligence to collect any amount payable in respect of such
      Collateral, but shall be liable only to account to Debtor for what it may
      actually collect or receive thereon. The provisions of this subparagraph
      are applicable whether or not a Default exists.

            (g) Cash Collateral Account. If a Default exists, Secured Party
      shall have, and Debtor hereby grants to Secured Party, the Right and
      authority to transfer all funds on deposit in the Deposit Accounts to a
      Cash Collateral Account (herein so called) maintained with a depository
      institution acceptable to Secured Party and subject to the exclusive
      direction, domain, and control of Secured Party, and no disbursements or
      withdrawals shall be permitted to be made by Debtor from such Cash
      Collateral Account. Such Cash Collateral Account shall be subject to the
      Security Interest and Liens in favor of Secured Party herein created, and
      Debtor hereby grants a security interest to Secured Party on behalf of
      Lenders in and to, such Cash Collateral Account and all checks, drafts,
      and other items ever received by Debtor for deposit therein. Furthermore,
      if a Default exists, Secured Party shall have the Right, at any time in
      its discretion without notice to Debtor, (i) to transfer to or to register
      in the name of Secured Party or any Lender or nominee any certificates of
      deposit or deposit instruments constituting Deposit Accounts and shall
      have the Right to exchange such certificates or instruments representing
      Deposit Accounts for certificates or instruments of smaller or larger
      denominations and (ii) to take and apply against the Obligation any and
      all funds then or thereafter on deposit in the Cash Collateral Account or
      otherwise constituting Deposit Accounts.

            (h) Power of Attorney. Debtor hereby irrevocably constitutes and
      appoints Secured Party as Debtor's attorney-in-fact, with full irrevocable
      power and authority in the place and stead of Debtor and in the name of
      Debtor, Secured Party, Lenders, or otherwise, from time to time in Secured
      Party's discretion, for the sole purpose of carrying out the terms of this
      Security Agreement and, to the extent permitted by applicable Law, to take
      any action and to execute any document and instrument which Secured Party
      may deem necessary or advisable to accomplish the following when a Default
      exists:

                  (i) to transfer any and all funds on deposit in the Deposit
            Accounts to the Cash Collateral Account as set forth in herein;

                  (ii) to receive, endorse, and collect any drafts or other
            instruments or documents in connection with clause (b) above and
            this clause (g);

                  (iii) to use the Patents and Trademarks or to grant or issue
            any exclusive or non-exclusive license under the Patents and
            Trademarks to anyone else, and to perform any act necessary for the
            Secured Party to assign, pledge, convey, or otherwise transfer title
            in or dispose of the Patents and Trademarks to any other Person; and

                  (iv) to execute on behalf of Debtor any financing statements
            or continuation statements with respect to the Security Interests
            created hereby, and to do any and all acts

<PAGE>

            and things to protect and preserve the Collateral, including,
            without limitation, the protection and prosecution of all Rights
            included in the Collateral.

            (i) Purchase Money Collateral. To the extent that Secured Party or
      any Lender has advanced or will advance funds to or for the account of
      Debtor to enable Debtor to purchase or otherwise acquire Rights in
      Collateral, Secured Party or such Lender, at its option, may pay such
      funds (i) directly to the Person from whom Debtor will make such purchase
      or acquire such Rights, or (ii) to Debtor, in which case Debtor covenants
      to promptly pay the same to such Person, and forthwith furnish to Secured
      Party evidence satisfactory to Secured Party that such payment has been
      made from the funds so provided.

            (j) Subrogation. If any of the Obligation is given in renewal or
      extension or applied toward the payment of indebtedness secured by any
      Lien, Secured Party shall be, and is hereby, subrogated to all of the
      Rights, titles, interests, and Liens securing the indebtedness so renewed,
      extended, or paid.

            (k) Indemnification. Debtor hereby assumes all liability for the
      Collateral, for the Security Interest, and for any use, possession,
      maintenance, and management of, all or any of the Collateral, including,
      without limitation, any Taxes arising as a result of, or in connection
      with, the transactions contemplated herein, and agrees to assume liability
      for, and to indemnify and hold Secured Party and each Lender harmless from
      and against, any and all claims, causes of action, or liability, for
      injuries to or deaths of Persons and damage to property, howsoever arising
      from or incident to such use, possession, maintenance, and management,
      whether such Persons be agents or employees of Debtor or of third parties,
      or such damage be to property of Debtor or of others. Debtor agrees to
      indemnify, save, and hold Secured Party and each Lender harmless from and
      against, and covenants to defend Secured Party and each Lender against,
      any and all losses, damages, claims, costs, penalties, liabilities, and
      expenses (collectively, "Claims"), including, without limitation, court
      costs and attorneys' fees, and any of the foregoing arising from the
      negligence of Secured Party or any Lender, or any of their respective
      officers, employees, agents, advisors, employees, or representatives,
      howsoever arising or incurred because of, incident to, or with respect to
      Collateral or any use, possession, maintenance, or management thereof;
      provided, however, that the indemnity set forth in this Paragraph 8(k)
      will not apply to Claims caused by the gross negligence or willful
      misconduct of Secured Party or any Lender.

      9. ACKNOWLEDGMENT OF REGULATORY CONSIDERATIONS

            (a) No Prohibited Transfers. It is hereby acknowledged that
      assignment or transfer of control of the FCC Licenses without the prior
      approval of the FCC may constitute a prohibited transfer in violation of
      FCC rules and regulations. Secured Party agrees that exercise of its
      Rights hereunder, including transfer of FCC Licenses upon the occurrence
      of a Default or Potential Default, shall be effected only after the
      obtaining of any necessary approvals for such exercise.

            (b) Actions by Debtor. If counsel to Secured Party reasonably
      determines that the consent of the FCC is required in connection with any
      of the actions which may be taken by Secured Party on behalf of Lenders in
      the exercise of their Rights hereunder or under the Loan Documents, then
      Debtor, at its sole cost and expense, agrees to use its best efforts to
      secure such consent and to cooperate with Secured Party and Lenders in any
      action commenced by Secured Party to secure such consent and in such case
      Debtor shall retain control of its respective FCC Licenses until the FCC
      shall have granted its consent to the transfer of the FCC Licenses and
      related permits. Upon the occurrence and during the continuation of a
      Default or Potential Default, Debtor shall promptly

<PAGE>

      execute or cause the execution of all applications, certificates,
      instruments, and other documents and papers that the Secured Party may be
      required to file in order to obtain any necessary governmental consent,
      approval, or authorization, and if Debtor fails or refuses to execute such
      documents, then, on the order of any court of competent jurisdiction, the
      Clerk of the Court with jurisdiction may execute such documents on behalf
      of Debtor. In addition, Debtor shall execute such applications and other
      documents and will take such other action as may be required in order for
      Secured Party to obtain from the FCC consent to operate the System,
      through a receiver or otherwise, during the time the Secured Party seeks
      to obtain a purchaser for the System and to submit any sale of the Systems
      to the FCC for approval. Debtor recognizes that FCC Licenses, franchises,
      and other similar agreements or authorizations are unique assets which (or
      the control of which) may have to be transferred in order for Lenders
      adequately to realize the value of their Security Interests. Debtor
      further recognizes that a violation of this covenant would result in
      irreparable harm to Lenders for which monetary damages are not readily
      ascertainable and which might not fully compensate such Lenders.
      Therefore, in addition to any other remedy which may be available to
      Lenders, at Law or in equity, Secured Party on behalf of Lenders shall
      have the remedy of specific performance of the provisions of this
      subsection.

            (c) FCC Approval. Notwithstanding anything to the contrary contained
      in this Security Agreement, Secured Party will not take any action
      pursuant to this Security Agreement or any of the documents executed
      pursuant hereto which would constitute an assignment of an FCC License or
      any transfer of control of an FCC License if such assignment of license or
      transfer of control would require under then-existing Law (including the
      written rules and regulations promulgated by the FCC or such other
      regulatory authority with jurisdiction) the prior approval of the FCC or
      such other regulatory authority with jurisdiction, without first obtaining
      such approval. Debtor agrees to take, or cause to be taken, any action
      which Secured Party may reasonably request in order to obtain and enjoy
      the full Rights and benefits granted to Secured Party by this Security
      Agreement and any other instruments or agreements executed pursuant
      hereto, including, without limitation, at Debtor's cost and expense, the
      exercise of its best efforts to cooperate in obtaining FCC approval of any
      action or transaction contemplated by this Security Agreement or any other
      instrument or agreement executed pursuant hereto which is then required by
      Law.

            (d) Subsequent Actions by Debtor. Debtor agrees that if, for any
      reason, the FCC or any such other regulatory authority with jurisdiction
      does not approve within a reasonable period of time the initial
      application for approval of the transfer of the FCC Licenses, then
      Paragraphs 9(b) and (c) above hereof shall be applicable to any subsequent
      application for transfer of the FCC Licenses pursuant to action taken by
      Secured Party in the exercise of its Rights hereunder or under the Loan
      Documents. With respect to each subsequent proposed purchaser(s), Debtor
      agrees to execute all such applications and other documents and take all
      such other action as may be reasonably requested by Secured Party at any
      time and from time to time in order to obtain the approval by the FCC or
      any other regulatory authorities. Exercise by Secured Party of the Right
      to such cooperation shall not be exhausted by the initial or any
      subsequent exercise thereof.

      10. MISCELLANEOUS.

            (a) Continuing Security Interest. This Security Agreement creates a
      continuing security interest in the Collateral and shall (i) remain in
      full force and effect until the termination of the obligations of Lenders
      to advance Borrowings or issue LCs under the Loan Documents, the payment
      in full of the Obligation, and the expiration of all LCs and all Financial
      Hedges issued by any Lender or any Affiliate of any Lender to
      Communications or any Company; (ii) be binding upon Debtor, its
      successors, and assigns; and (iii) inure to the benefit of and be
      enforceable by Secured Party,

<PAGE>

      Lenders, and their respective successors, transferees, and assigns.
      Without limiting the generality of the foregoing clause (iii), Secured
      Party and Lenders may assign or otherwise transfer any of their respective
      Rights under this Security Agreement to any other Person in accordance
      with the terms and provisions of Section 13.13 of the Credit Agreement,
      and to the extent of such assignment or transfer such Person shall
      thereupon become vested with all the Rights and benefits in respect
      thereof granted herein or otherwise to the Secured Party or Lenders, as
      the case may be. Upon payment in full of the Obligation, the termination
      of the commitment of Lenders to extend credit or issue LCs under the Loan
      Documents, and the expiration of all LCs or Financial Hedges issued by any
      Lender or any Affiliate of any Lender to Communications or any Company,
      Debtor shall be entitled to the return, upon its request and at its
      expense, of such of the Collateral as shall not have been sold or
      otherwise applied pursuant to the terms hereof.

            (b) Reference to Miscellaneous Provisions. This Security Agreement
      is one of the "Loan Documents" referred to in the Credit Agreement, and
      all provisions relating to Loan Documents set forth in Section 13 of the
      Credit Agreement, other than the provisions set forth in Section 13.7, are
      incorporated herein by reference, the same as if set forth herein
      verbatim.

            (c) Term. Upon full and final payment and performance of the
      Obligation, this Security Agreement shall thereafter terminate upon
      receipt by Secured Party of Debtor's written notice of such termination;
      provided that no Obligor, if any, on any of the Collateral shall ever be
      obligated to make inquiry as to the termination of this Security
      Agreement, but shall be fully protected in making payment directly to
      Secured Party until actual notice of such total payment of the Obligation
      is received by such Obligor.

            (d) Actions Not Releases. The Security Interest and Debtor's
      obligations and Secured Party's Rights hereunder shall not be released,
      diminished, impaired, or adversely affected by the occurrence of any one
      or more of the following events: (i) the taking or accepting of any other
      security or assurance for any or all of the Obligation; (ii) any release,
      surrender, exchange, subordination, or loss of any security or assurance
      at any time existing in connection with any or all of the Obligation;
      (iii) the modification of, amendment to, or waiver of compliance with any
      terms of any of the other Loan Documents without the notification or
      consent of Debtor, except as required therein (the Right to such
      notification or consent being herein specifically waived by Debtor); (iv)
      the insolvency, bankruptcy, or lack of corporate or trust power of any
      party at any time liable for the payment of any or all of the Obligation,
      whether now existing or hereafter occurring; (v) any renewal, extension,
      or rearrangement of the payment of any or all of the Obligation, either
      with or without notice to or consent of Debtor, or any adjustment,
      indulgence, forbearance, or compromise that may be granted or given by
      Secured Party or any Lender to Debtor; (vi) any neglect, delay, omission,
      failure, or refusal of Secured Party or any Lender to take or prosecute
      any action in connection with any other agreement, document, guaranty, or
      instrument evidencing, securing, or assuring the payment of all or any of
      the Obligation; (vii) any failure of Secured Party or any Lender to notify
      Debtor of any renewal, extension, or assignment of the Obligation or any
      part thereof, or the release of any Collateral or other security, or of
      any other action taken or refrained from being taken by Secured Party or
      any Lender against Debtor or any new agreement between or among Secured
      Party or one or more Lenders and Debtor, it being understood that neither
      Secured Party nor any Lender shall be required to give Debtor any notice
      of any kind under any circumstances whatsoever with respect to or in
      connection with the Obligation, including, without limitation, notice of
      acceptance of this Security Agreement or any Collateral ever delivered to
      or for the account of Secured Party hereunder; (viii) the illegality,
      invalidity, or unenforceability of all or any part of the Obligation
      against any party obligated with respect thereto by reason of the fact
      that the Obligation, or the interest paid or payable with respect thereto,
      exceeds the amount permitted by Law, the act of

<PAGE>

      creating the Obligation, or any part thereof, is ultra vires, or the
      officers, partners, or trustees creating same acted in excess of their
      authority, or for any other reason; or (ix) if any payment by any party
      obligated with respect thereto is held to constitute a preference under
      applicable Laws or for any other reason Secured Party or any Lender is
      required to refund such payment or pay the amount thereof to someone else.

            (e) Waivers. Except to the extent expressly otherwise provided
      herein or in other Loan Documents and to the fullest extent permitted by
      applicable Law, Debtor waives (i) any Right to require Secured Party or
      any Lender to proceed against any other Person, to exhaust its Rights in
      Collateral, or to pursue any other Right which Secured Party or any Lender
      may have; (ii) with respect to the Obligation, presentment and demand for
      payment, protest, notice of protest and nonpayment, and notice of the
      intention to accelerate; and (iii) all Rights of marshaling in respect of
      any and all of the Collateral.

            (f) Financing Statement. Secured Party shall be entitled at any time
      to file this Security Agreement or a carbon, photographic, or other
      reproduction of this Security Agreement, as a financing statement, but the
      failure of Secured Party to do so shall not impair the validity or
      enforceability of this Security Agreement.

            (g) Amendments. This Security Agreement may be amended only by an
      instrument in writing executed jointly by Debtor and Secured Party, and
      supplemented only by documents delivered or to be delivered in accordance
      with the express terms hereof.

            (h) Multiple Counterparts. This Security Agreement has been executed
      in a number of identical counterparts, each of which shall be deemed an
      original for all purposes and all of which constitute, collectively, one
      agreement; but, in making proof of this Security Agreement, it shall not
      be necessary to produce or account for more than one such counterpart.

            (i) Parties Bound; Assignment. This Security Agreement shall be
      binding on Debtor and Debtor's heirs, legal representatives, successors,
      and assigns and shall inure to the benefit of Secured Party and Secured
      Party's successors and assigns.

                  (i) Secured Party is the agent for each Lender under the
            Credit Agreement, the Security Interest and all Rights granted to
            Secured Party hereunder or in connection herewith are for the
            ratable benefit of each Lender, and Secured Party may, without the
            joinder of any Lender, exercise any and all Rights in favor of
            Secured Party or Lenders hereunder, including, without limitation,
            conducting any foreclosure sales hereunder, and executing full or
            partial releases hereof, amendments or modifications hereto, or
            consents or waivers hereunder. The Rights of each Lender vis-a-vis
            Secured Party and each other Lender may be subject to one or more
            separate agreements between or among such parties, but Debtor need
            not inquire about any such agreement or be subject to any terms
            thereof unless Debtor specifically joins therein; and consequently,
            neither Debtor nor Debtor's heirs, personal representatives,
            successors, and assigns shall be entitled to any benefits or
            provisions of any such separate agreements or be entitled to rely
            upon or raise as a defense, in any manner whatsoever, the failure or
            refusal of any party thereto to comply with the provisions thereof.

                  (ii) Debtor may not, without the prior written consent of
            Secured Party, assign any Rights, duties, or obligations hereunder.

            (j) GOVERNING LAW. PURSUANT TO SECTION 5-1401 OF THE NEW YORK
      GENERAL OBLIGATIONS LAW, THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK
      APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH
      STATE, WITHOUT REGARD TO THE CHOICE OF LAW PRINCIPLES THAT MIGHT OTHERWISE

            limitation the Deposit Accounts Listed on Addendum(1)

      This will confirm that (the "Company") and the undersigned Deposit Bank
have agreed as follows with respect to the Accounts:

      1. The Company and the Deposit Bank acknowledge and confirm that all funds
now or at any time hereafter deposited to the Accounts and all of the Company's
rights regarding such Accounts constitute part of the "Collateral" granted to
Administrative Agent by the Company to secure the Company's obligations under
the Credit Agreement and/or related Loan Documents and that Administrative Agent
holds a security interest and collateral assignment therein.

      2. The Deposit Bank (excluding any Deposit Bank which is a Lender under
the Credit Agreement) will not exercise, and hereby releases, any banker's lien
upon, and any right of setoff against, the Accounts or any funds at any time
deposited to the Accounts except with respect to the Deposit Bank's normal fees
and charges for operating the Accounts.

      3. The Deposit Bank will take the following actions upon written demand by
Administrative Agent:

            A. The Deposit Bank will (and in the event of such demand the
      Company hereby irrevocably authorizes and instructs the Deposit Bank to)
      cease honoring all drafts, demands, withdrawal requests, or remittance
      instructions by the Company, whether made before or after the demand.

            B. The Deposit Bank will hold solely for account of Administrative
      Agent all funds which may be on deposit in the Accounts at the time of the
      demand and all funds thereafter deposited to the Accounts, and, upon
      instructions from Administrative Agent, the Deposit Bank will remit all
      such funds (subject to Paragraph 2 above) to Administrative Agent in such
      manner as Administrative Agent may from time to time instruct the Deposit
      Bank in writing.

over the Accounts and the sole right to exercise and enforce all rights and
remedies with respect thereto. The demand shall be effective when it is received

stop payment instructions generally, to act thereon.

its successors and assigns. It supersedes all prior agreements relating to the
Deposit Bank, and it may not be modified or terminated except upon

              FORM OF AMENDED AND RESTATED PLEDGE, ASSIGNMENT, AND
            SECURITY AGREEMENT FOR DOBSON COMMUNICATIONS CORPORATION

      THIS AMENDED AND RESTATED PLEDGE, ASSIGNMENT, AND SECURITY AGREEMENT (this
"Pledge Agreement") is executed as of ____________, 2000, by DOBSON
COMMUNICATIONS CORPORATION, an Oklahoma corporation ("Debtor"), whose address is
_________________________, and BANK OF AMERICA, N.A., a national banking
association, (in its capacity as "Administrative Agent" for the holders of the
Obligation under the Credit Agreement defined below), as "Secured Party," whose
address is 901 Main Street, Suite 3100, Dallas, Texas 75202.

                                    RECITALS

      A. Dobson Operating Co., L.L.C. (successor by merger with Dobson Operating
Company and Dobson Cellular Operations Company, "Borrower") has entered into an
Amended, Restated, and Consolidated Revolving Credit and Term Loan Agreement (as
amended, modified, supplemented, or restated from time to time, the "Credit
Agreement") dated as of January 18, 2000, with Bank of America, N.A., as
Administrative Agent (including its permitted successors and assigns in such
capacity, the "Administrative Agent"), and the Lenders now or hereafter party to
the Credit Agreement (including their respective permitted successors and
assigns, the "Lenders"), which Credit Agreement amends, restates, and
consolidates the Existing Credit Agreements (as such term is described and
defined in the Credit Agreement).

      B. To assure payment and performance of the Obligation under the Existing
DOC Credit Agreements, Debtor executed an Amended and Restated Pledge Agreement
dated March 25, 1998, executed by Dobson Communications Corporation, as Debtor,
and Administrative Agent under the Existing DOC Credit Agreement, for the
benefit of Lenders thereunder, as Secured Party (the "Existing Communications
Pledge Agreement").

      C. In connection with the execution of and as a condition of the
effectiveness of, the Credit Agreement, the Existing Communications Pledge
Agreements are required to be (and are hereby) amended, restated, and
consolidated in their entirety.

      D. This Pledge Agreements is integral to the transactions contemplated by
the Loan Documents, and the execution and delivery thereof, is a condition
precedent to Lenders' obligations to extend credit under the Loan Documents.

      ACCORDINGLY, for valuable consideration, the receipt and adequacy of which
are hereby acknowledged, Debtor and Secured Party hereby agree as follows:

      1. REFERENCE TO CREDIT AGREEMENT. The terms, conditions, and provisions of
the Credit Agreement are incorporated herein by reference, the same as if set
forth herein verbatim, which terms, conditions, and provisions shall continue to
be in full force and effect hereunder so long as Lenders are obligated to lend
under the Credit Agreement and thereafter until the Obligation is paid and
performed in full.

      2. CERTAIN DEFINITIONS. Unless otherwise defined herein, or the context
hereof otherwise requires, each term defined in either of the Credit Agreement
or in the UCC is used in this Pledge Agreement with the same meaning; provided
that (a) if the definition given to such term in the Credit Agreement conflicts
with the definition given to such term in the UCC, the Credit Agreement
definition shall control to the extent legally allowable; and (b) if any
definition given to such term in Chapter 9 of the UCC

<PAGE>

conflicts with the definition given to such term in any other chapter of the
UCC, the Chapter 9 definition shall prevail. As used herein, the following terms
have the meanings indicated:

            Collateral has the meaning set forth in Paragraph 4 hereof.

            Lender means, individually, or Lenders means, collectively, on any
      date of determination, the Administrative Agent and Lenders and their
      permitted successors and assigns.

            Obligation means, collectively, (a) the "Obligation" as defined in
      the Credit Agreement and (b) all indebtedness, liabilities, and
      obligations of Debtor arising under this Pledge Agreement or Guaranty
      assuring payment of the Obligation; it being the intention and
      contemplation of Debtor and Secured Party that future advances will be
      made by Secured Party or one or more Lenders to Debtor for a variety of
      purposes, that Debtor may guarantee (or otherwise become directly or
      contingently obligated with respect to) the obligations of others to
      Secured Party or to one or more Lenders, that from time to time overdrafts
      of Debtor's accounts with Secured Party or with other Lenders may occur,
      and that Secured Party or one or more Lenders may from time to time
      acquire from others obligations of Debtor to such others, and that payment
      and repayment of all of the foregoing are intended to and shall be part of
      the Obligation secured hereby. The Obligation shall include, without
      limitation, future, as well as existing, advances, indebtedness,
      liabilities, and obligations owed by Debtor to Secured Party or to any
      Lender arising under the Loan Documents or otherwise.

            Obligor means any Person obligated with respect to any of the
      Collateral, whether as an obligor on an instrument, issuer of securities,
      or otherwise.

            Pledged Securities means, collectively, the Pledged Shares and any
      other Collateral constituting securities;

            Security Interest means the security interest granted and the pledge
      and assignment made under Paragraph 3 hereof.

            UCC means the Uniform Commercial Code, including each such provision
      as it may subsequently be renumbered, as enacted in the State of New York
      or other applicable jurisdiction, as amended at the time in question.

      3. SECURITY INTEREST. In order to secure the full and complete payment and
performance of the Obligation when due, Debtor hereby grants to Secured Party a
Security Interest in all of Debtor's Rights, titles, and interests in and to the
Collateral and pledges, collaterally transfers, and assigns the Collateral to
Secured Party, all upon and subject to the terms and conditions of this Pledge
Agreement. Such Security Interest is granted and pledge and assignment are made
as security only and shall not subject Secured Party to, or transfer or in any
way affect or modify, any obligation of Debtor with respect to any of the
Collateral or any transaction involving or giving rise thereto.

      4. COLLATERAL. As used herein, the term "Collateral" means the following
items and types of property:

            (a) All present and future issued and outstanding shares of capital
      stock or other equity or investment securities issued by or other
      interests (including membership interests or limited liability company
      interests) in Borrower, now owned or hereafter acquired by Debtor,
      together with all Distributions thereon, all cash and noncash proceeds
      thereof, and any securities issued in

<PAGE>

      substitution or replacement thereof (collectively, the "Pledged Shares"),
      including, without limitation, the Pledged Shares described on Annex B..

            (b) All present and future increases, profits, combinations,
      reclassifications, and substitutes and replacements for, all or part of
      the Collateral heretofore described.

            (c) All present and future accounts, contract Rights, general
      intangibles, chattel paper, documents, instruments, cash and noncash
      proceeds, and other Rights arising from or by virtue of, or from the
      voluntary or involuntary sale or other disposition of, or collections with
      respect to, or insurance proceeds payable with respect to, or claims
      against any other Person with respect to, all or any part of the
      Collateral heretofore described in this clause or otherwise.

The description of the Collateral contained in this Paragraph 4 shall not be
deemed to permit any action prohibited by this Pledge Agreement or by the terms
incorporated in this Pledge Agreement. Furthermore, notwithstanding any contrary
provision, Debtor agrees that, if, but for the application of this paragraph,
granting a Security Interest in the Collateral would constitute a fraudulent
conveyance under 11 U.S.C. ss. 548 or a fraudulent conveyance or transfer under
any state fraudulent conveyance, fraudulent transfer, or similar Law in effect
from time to time (each a "fraudulent conveyance"), then the Security Interest
remains enforceable to the maximum extent possible without causing such Security
Interest to be a fraudulent conveyance, and this Pledge Agreement is
automatically amended to carry out the intent of this paragraph.

      5. REPRESENTATIONS AND WARRANTIES. Debtor represents and warrants to
Secured Party that:

            (a) Credit Agreement. Certain representations and warranties in the
      Credit Agreement are applicable to it or its assets or operations, and
      each such representation and warranty is true and correct.

            (b) Binding Obligation. This Pledge Agreement creates a legal,
      valid, and binding Lien in and to the Collateral in favor of Secured Party
      and enforceable against Debtor. For Collateral in which the Security
      Interest may be perfected by the filing of Financing Statements, once
      those Financing Statements have been properly filed in the jurisdictions
      described on Annex A hereto, the Security Interest in that Collateral will
      be fully perfected. Once perfected and, in the case of investment property
      or instruments, upon possession or "control" (within the meaning of
      Sections 8-106 and 9-115 of the UCC) by Secured Party, the Security
      Interest will constitute a first-priority Lien on the Collateral. The
      creation of the Security Interest does not require the consent of any
      Person that has not been obtained.

            (c) Location. Debtor's place of business and chief executive office
      is where Debtor is entitled to receive notices hereunder.

            (d) Securities. All Collateral that is Pledged Securities is duly
      authorized, validly issued, fully paid, and non-assessable, and the
      transfer thereof is not subject to any restrictions, other than
      restrictions imposed by applicable securities and corporate Laws. The
      Pledged Shares constitute one hundred percent (100%) of the issued and
      outstanding capital stock or other equity or investment securities issued
      by or other interests (including membership interests or limited liability
      company interests) in Borrower. Debtor has good title to the Collateral,
      free and clear of all liens and encumbrances thereon (except for the
      Security Interest created hereby), and has delivered to Secured Party all
      stock certificates, promissory notes, bonds, debentures, or other
      instruments or documents representing or evidencing the Collateral,
      together with corresponding assignment or

<PAGE>

      transfer powers duly executed in blank by Debtor, and such powers have
      been duly and validly executed and are binding and enforceable against
      Debtor in accordance with their terms; and the pledge of the Collateral in
      accordance with the terms hereof creates a valid and perfected first
      priority Security Interest in the Collateral securing payment of the
      Obligation.

            (e) Governmental Authority. No authorization, approval, or other
      action by, and no notice to or filing with, any Governmental Authority is
      required either (i) for the pledge by Debtor of the Pledged Securities
      pursuant to this Pledge Agreement or for the execution, delivery, or
      performance of this Pledge Agreement by Debtor, or (ii) for the exercise
      by Secured Party of the voting or other Rights provided for in this Pledge
      Agreement or the remedies in respect of the Collateral pursuant to this
      Pledge Agreement (except as may be required in connection with the
      disposition of the Pledged Securities by Laws affecting the offering and
      sale of securities generally and in connection with the transfer of
      control of the Authorizations).

            (f) Liens. Debtor owns all presently existing Collateral, and will
      acquire all hereafter-acquired Collateral, free and clear of all Liens.

The foregoing representations and warranties will be true and correct in all
respects with respect to any additional Collateral or additional specific
descriptions of certain Collateral delivered to Secured Party in the future by
Debtor.

      The failure of any of these representations or warranties to be accurate
and complete does not impair the Security Interest in any Collateral.

      6. COVENANTS. So long as Lenders are committed to extend credit to
Borrower under the Credit Agreement and until the Obligation is paid and
performed in full, Debtor covenants and agrees with Secured Party that Debtor
will:

            (a) Credit Agreement. (i) Comply with, perform, and be bound by all
      covenants and agreements in the Credit Agreement that are applicable to
      it, its assets, or its operations, each of which is hereby ratified and
      confirmed (INCLUDING, WITHOUT LIMITATION, THE INDEMNIFICATION AND RELATED
      PROVISIONS IN SECTION 11.12 OF THE CREDIT AGREEMENT); AND (ii) CONSENT TO
      AND APPROVE THE VENUE, SERVICE OF PROCESS, AND WAIVER OF JURY TRIAL
      PROVISIONS OF SECTION 13.10 OF THE CREDIT AGREEMENT.

            (b) Perform Obligations. Fully perform all of Debtor's duties under
      and in connection with each transaction to which the Collateral, or any
      part thereof, relates, so that the amounts thereof shall actually become
      payable in their entirety to Secured Party.

            (c) Notices. (i) Promptly notify Secured Party of (A) any change in
      any fact or circumstances represented or warranted by Debtor with respect
      to any of the Collateral or Obligation, and (B) any claim, action, or
      proceeding affecting title to all or any of the Collateral or the Security
      Interest and, at the request of Secured Party, appear in and defend, at
      Debtor's expense, any such action or proceeding; and (ii) give Secured
      Party 30 days written notice before any proposed (A) relocation of its
      principal place of business or chief executive office and (B) change of
      its name, identity, or corporate structure. Prior to making any of the
      changes contemplated in clause (ii) preceding, Secured Party shall execute
      and deliver all such additional documents and perform all additional acts
      as Secured Party, in its sole discretion, may request in order to continue
      or maintain the existence and priority of the Security Interests in all of
      the Collateral.

<PAGE>

            (d) Collateral in Trust. Hold in trust (and not commingle with other
      assets of Debtor) for Secured Party all Collateral that is chattel paper,
      instruments, Pledged Securities, or documents at any time received by
      Debtor, and promptly deliver same to Secured Party, unless Secured Party
      at its option (which may be evidenced only by a writing signed by Secured
      Party stating that Secured Party elects to permit Debtor to so retain)
      permits Debtor to retain the same, but any Collateral so retained shall be
      marked to state that it is assigned to Secured Party.

            (e) Further Assurances. At Debtor's expense and Secured Party's
      request, before or after a Default or Potential Default, (i) file or cause
      to be filed such applications and take such other actions as Secured Party
      may request to obtain the consent or approval of any Governmental
      Authority to Secured Party's Rights hereunder, including, without
      limitation, the Right to sell all the Collateral upon a Default or
      Potential Default without additional consent or approval from such
      Governmental Authority (and, because Debtor agrees that Secured Party's
      remedies at Law for failure of Debtor to comply with this provision would
      be inadequate and that such failure would not be adequately compensable in
      damages, Debtor agrees that its covenants in this provision may be
      specifically enforced); (ii) from time to time promptly execute and
      deliver to Secured Party all such other assignments, certificates,
      supplemental documents, and financing statements, and do all other acts or
      things as Secured Party may reasonably request in order to more fully
      create, evidence, perfect, continue, and preserve the priority of the
      Security Interest; and (iii) pay all filing fees in connection with any
      financing, continuation, or termination statement or other instrument with
      respect to the Security Interests.

            (f) Modifications to Agreements. Not modify or substitute, or permit
      the modification or substitution of, any document evidencing the
      Collateral or contract to which any of the Collateral relates.

            (g) Securities. Not sell, exchange, or otherwise dispose of, or
      grant any option, warrant, or other Right with respect to, any of the
      Collateral; cause Borrower not to issue any stock or other securities in
      addition to or in substitution for the Pledged Securities issued by
      Borrower, except to Debtor; pledge hereunder, immediately upon Debtor's
      acquisition (directly or indirectly) thereof, any and all additional
      shares of stock or other securities of Borrower issued to Debtor; and take
      any action necessary, required, or requested by Secured Party to allow
      Secured Party to fully enforce its Security Interest in the Collateral,
      including, without limitation, the filing of any claims with any court,
      liquidator, trustee, custodian, receiver, or other like person or party.

      7. DEFAULT; REMEDIES. If a Default or a Potential Default exists, Secured
Party may, at its election (but subject to the terms and conditions of the
Credit Agreement), exercise any and all Rights available to a Secured Party
under the UCC, in addition to any and all other Rights afforded by the Loan
Documents, at Law, in equity, or otherwise, including, without limitation, (a)
applying by appropriate judicial proceedings for appointment of a receiver for
all or part of the Collateral (and Debtor hereby consents to any such
appointment), and (b) applying to the Obligation any cash held by Secured Party
under this Pledge Agreement, if any. Notwithstanding the foregoing, Secured
Party will not exercise any remedies against the assets of Debtor unless it has
given at least ten days written notification to Debtor, to the FCC, to the
extent such notice is required under 47 C.F.R. 22.937(f), and to any other
Governmental Authority, to the extent such notice is required by Law.

            (a) Notice. Reasonable notification of the time and place of any
      public sale of the Collateral, or reasonable notification of the time
      after which any private sale or other intended disposition of the
      Collateral is to be made, shall be sent to Debtor and to any other Person
      entitled to notice under the UCC; provided, that if any of the Collateral
      threatens to decline speedily in value

<PAGE>

      or is of the type customarily sold on a recognized market, Secured Party
      may sell or otherwise dispose of the Collateral without notification,
      advertisement, or other notice of any kind. It is agreed that notice sent
      or given not less than ten Business Days prior to the taking of the action
      to which the notice relates is reasonable notification and notice for the
      purposes of this subparagraph.

            (b) Sales of Pledged Securities.

                  (i) Debtor agrees that, because of the Securities Act of 1933,
            as amended, or the rules and regulations promulgated thereunder
            (collectively, the "Securities Act"), or any other Laws or
            regulations, and for other reasons, there may be legal or practical
            restrictions or limitations affecting Secured Party in any attempts
            to dispose of certain portions of the Pledged Securities and for the
            enforcement of its Rights. For these reasons, Secured Party is
            hereby authorized by Debtor, but not obligated, upon the occurrence
            and during the continuation of a Default or Potential Default, to
            sell all or any part of the Pledged Securities at private sale,
            subject to investment letter or in any other manner which will not
            require the Pledged Securities, or any part thereof, to be
            registered in accordance with the Securities Act or any other Laws
            or regulations, at a reasonable price at such private sale or other
            distribution in the manner mentioned above. Debtor understands that
            Secured Party may in its discretion approach a limited number of
            potential purchasers and that a sale under such circumstances may
            yield a lower price for the Pledged Securities, or any part thereof,
            than would otherwise be obtainable if such Pledged Securities were
            either afforded to a larger number or potential purchasers,
            registered under the Securities Act, or sold in the open market.
            Debtor agrees that any such private sale made under this Paragraph
            7(a) shall be deemed to have been made in a commercially reasonable
            manner, and that Secured Party has no obligation to delay the sale
            of any Pledged Securities to permit the issuer thereof to register
            it for public sale under any applicable federal or state securities
            Laws.

                  (ii) Secured Party is authorized, in connection with any such
            sale, (A) to restrict the prospective bidders on or purchasers of
            any of the Pledged Securities to a limited number of sophisticated
            investors who will represent and agree that they are purchasing for
            their own account for investment and not with a view to the
            distribution or sale of any of such Pledged Securities, and (B) to
            impose such other limitations or conditions in connection with any
            such sale as Secured Party reasonably deems necessary in order to
            comply with applicable Law. Debtor covenants and agrees that it will
            execute and deliver such documents and take such other action as
            Secured Party reasonably deems necessary in order that any such sale
            may be made in compliance with applicable Law. Upon any such sale
            Secured Party shall have the Right to deliver, assign, and transfer
            to the purchaser thereof the Pledged Securities so sold. Each
            purchaser at any such sale shall hold the Pledged Securities so sold
            absolutely, free from any claim or Right of Debtor of whatsoever
            kind, including any equity or Right of redemption of Debtor. Debtor,
            to the extent permitted by applicable Law, hereby specifically
            waives all Rights of redemption, stay, or appraisal which it has or
            may have under any Law now existing or hereafter enacted.

                  (iii) Debtor agrees that five (5) days' written notice from
            Secured Party to Debtor of Secured Party's intention to make any
            such public or private sale or sale at a broker's board or on a
            securities exchange shall constitute "reasonable notification"
            within the meaning of Section 9-504(c) of the UCC. Such notice shall
            (A) in case of a public sale, state the time and place fixed for
            such sale, (B) in case of sale at a broker's board or on a
            securities exchange, state the board or exchange at which such a
            sale is to be made and the day on which the Pledged Securities, or
            the portion thereof so being sold, will first be

<PAGE>

            offered to sale at such board or exchange, and (C) in the case of a
            private sale, state the day after which such sale may be
            consummated. Any such public sale shall be held at such time or
            times within ordinary business hours and at such place or places as
            Secured Party may fix in the notice of such sale. At any such sale,
            the Pledged Securities may be sold in one lot as an entirety or in
            separate parcels, as Secured Party may reasonably determine. Secured
            Party shall not be obligated to make any such sale pursuant to any
            such notice. Secured Party may, without notice or publication,
            adjourn any public or private sale or cause the same to be adjourned
            from time to time by announcement at the time and place fixed for
            the sale, and such sale may be made at any time or place to which
            the same may be so adjourned.

                  (iv) In case of any sale of all or any part of the Pledged
            Securities on credit or for future delivery, the Pledged Securities
            so sold may be retained by Secured Party until the selling price is
            paid by the purchaser thereof, but Secured Party shall not incur any
            liability in case of the failure of such purchaser to take up and
            pay for the Pledged Securities so sold and in case of any such
            failure, such Pledged Securities may again be sold upon like notice.
            Secured Party, instead of exercising the power of sale herein
            conferred upon it, may proceed by a suit or suits at law or in
            equity to foreclose the Security Interests and sell the Pledged
            Securities, or any portion thereof, under a judgment or decree of a
            court or courts of competent jurisdiction.

                  (v) Without limiting the foregoing, or imposing upon Secured
            Party any obligations or duties not required by applicable Law,
            Debtor acknowledges and agrees that, in foreclosing upon any of the
            Pledged Securities, or exercising any other Rights or remedies
            provided Secured Party hereunder or under applicable Law, Secured
            Party may, but shall not be required to, (A) qualify or restrict
            prospective purchasers of the Pledged Securities by requiring
            evidence of sophistication or creditworthiness, and requiring the
            execution and delivery of confidentiality agreements or other
            documents and agreements as a condition to such prospective
            purchasers' receipt of information regarding the Pledged Securities
            or participation in any public or private foreclosure sale process,
            (B) provide to prospective purchasers business and financial
            information regarding Debtor or the Companies available in the files
            of Secured Party at the time of commencing the foreclosure process,
            without the requirement that Secured Party obtain, or seek to
            obtain, any updated business or financial information or verify, or
            certify to prospective purchasers, the accuracy of any such business
            or financial information, or (C) offer for sale and sell the Pledged
            Securities with, or without, first employing an appraiser,
            investment banker, or broker with respect to the evaluation of the
            Pledged Securities, the solicitation of purchasers for Pledged
            Securities, or the manner of sale of Pledged Securities.

            (c) Application of Proceeds. Secured Party shall apply the proceeds
      of any sale or other disposition of the Collateral under this Paragraph 7
      in the following order: first, to the payment of all expenses incurred in
      retaking, holding, and preparing any of the Collateral for sale(s) or
      other disposition, in arranging for such sale(s) or other disposition, and
      in actually selling or disposing of the same (all of which are part of the
      Obligation); second, toward repayment of amounts expended by Secured Party
      under Paragraph 8; and third, toward payment of the balance of the
      Obligation in the order and manner specified in the Credit Agreement. Any
      surplus remaining shall be delivered to Debtor or as a court of competent
      jurisdiction may direct. If the proceeds are insufficient to pay the
      Obligation in full, Debtor shall remain liable for any deficiency.

      8. OTHER RIGHTS OF SECURED PARTY.

<PAGE>

            (a) Performance. If Debtor fails to preserve the priority of the
      Security Interest in any of the Collateral or otherwise fails to perform
      any of its obligations under the Loan Documents with respect to the
      Collateral, then Secured Party may, at its option, but without being
      required to do so, prosecute or defend any suits in relation to the
      Collateral, or take all other action which Debtor is required, but has
      failed or refused, to take under the Loan Documents. Any sum which may be
      expended or paid by Secured Party under this subparagraph (including,
      without limitation, court costs and attorneys' fees) shall bear interest
      from the dates of expenditure or payment at the Default Rate until paid
      and, together with such interest, shall be payable by Debtor to Secured
      Party upon demand and shall be part of the Obligation.

            (b) Collection. If a Default or Potential Default exists and upon
      notice from Secured Party, each Obligor with respect to any payments on
      any of the Collateral (including, without limitation, dividends and other
      distributions with respect to Pledged Securities) is hereby authorized and
      directed by Debtor to make payment directly to Secured Party, regardless
      of whether Debtor was previously making collections thereon. Subject to
      Paragraph 8(e) hereof, until such notice is given, Debtor is authorized to
      retain and expend all payments made on Collateral. If a Default or
      Potential Default exists, Secured Party shall have the Right in its own
      name or in the name of Debtor to compromise or extend time of payment with
      respect to all or any portion of the Collateral for such amounts and upon
      such terms as Secured Party may determine; to demand, collect, receive,
      receipt for, sue for, compound, and give acquittances for any and all
      amounts due or to become due with respect to Collateral; to take control
      of cash and other proceeds of any Collateral; to endorse the name of
      Debtor on any notes, acceptances, checks, drafts, money orders, or other
      evidences of payment on Collateral that may come into the possession of
      Secured Party; to sign the name of Debtor on any invoice or bill of lading
      relating to any Collateral, on any drafts against Obligors or other
      Persons making payment with respect to Collateral, on assignments and
      verifications of accounts or other Collateral and on notices to Obligors
      making payment with respect to Collateral; to send requests for
      verification of obligations to any Obligor; and to do all other acts and
      things necessary to carry out the intent of this Pledge Agreement. If a
      Default or Potential Default exists and any Obligor fails or refuses to
      make payment on any Collateral when due, Secured Party is authorized, in
      its sole discretion, either in its own name or in the name of Debtor, to
      take such action as Secured Party shall deem appropriate for the
      collection of any amounts owed with respect to Collateral or upon which a
      delinquency exists. Regardless of any other provision hereof, however,
      Secured Party shall never be liable for its failure to collect, or for its
      failure to exercise diligence in the collection of, any amounts owed with
      respect to Collateral, nor shall it be under any duty whatsoever to anyone
      except Debtor to account for funds that it shall actually receive
      hereunder. Without limiting the generality of the foregoing, Secured Party
      shall have no responsibility for ascertaining any maturities, calls,
      conversions, exchanges, offers, tenders, or similar matters relating to
      any Collateral, or for informing Debtor with respect to any of such
      matters (irrespective of whether Secured Party actually has, or may be
      deemed to have, knowledge thereof). The receipt of Secured Party to any
      Obligor shall be a full and complete release, discharge, and acquittance
      to such Obligor, to the extent of any amount so paid to Secured Party.

            (c) Record Ownership of Securities. If a Default or Potential
      Default exists, Secured Party at any time may have any Collateral that is
      Pledged Securities and that is in the possession of Secured Party, or its
      nominee or nominees, registered in its name, or in the name of its nominee
      or nominees, as Secured Party; and, as to any Collateral that is Pledged
      Securities so registered, Secured Party shall execute and deliver (or
      cause to be executed and delivered) to Debtor all such proxies, powers of
      attorney, dividend coupons or orders, and other documents as Debtor may
      reasonably request for the purpose of enabling Debtor to exercise the
      voting Rights and powers which it is

<PAGE>

      entitled to exercise under this Pledge Agreement or to receive the
      dividends and other payments in respect of such Collateral that is Pledged
      Securities which it is authorized to receive and retain under this Pledge
      Agreement.

            (d) Voting of Securities. As long as neither a Default nor Potential
      Default exists, Debtor is entitled to exercise all voting Rights
      pertaining to any Pledged Securities; provided, however, that no vote
      shall be cast or consent, waiver, or ratification given or action taken
      without the prior written consent of Secured Party which would (x) be
      inconsistent with or violate any provision of this Pledge Agreement or any
      other Loan Document or (y) amend, modify, or waive any term, provision or
      condition of the certificate of incorporation, bylaws, certificate of
      formation, or other charter document, or other agreement relating to,
      evidencing, providing for the issuance of, or securing any Collateral; and
      provided further that Debtor shall give Secured Party at least five
      Business Days' prior written notice in the form of an officers'
      certificate of the manner in which it intends to exercise, or the reasons
      for refraining from exercising, any voting or other consensual Rights
      pertaining to the Collateral or any part thereof which might have a
      material adverse effect on the value of the Collateral or any part
      thereof. If a Default or Potential Default exists and if Secured Party
      elects to exercise such Right, the Right to vote any Pledged Securities
      shall be vested exclusively in Secured Party. To this end, Debtor hereby
      irrevocably constitutes and appoints Secured Party the proxy and
      attorney-in-fact of Debtor, with full power of substitution, to vote, and
      to act with respect to, any and all Collateral standing in the name of
      Debtor or with respect to which Debtor is entitled to vote and act,
      subject to the understanding that such proxy may not be exercised unless a
      Default exists. The proxy herein granted is coupled with an interest, is
      irrevocable, and shall continue until the Obligation has been paid and
      performed in full.

            (e) Certain Proceeds. Notwithstanding any contrary provision herein,
      any and all

                  (i) dividends, interest, or other Distributions paid or
            payable other than in cash in respect of, and instruments and other
            property received, receivable, or otherwise distributed in respect
            of, or in exchange for, any Collateral;

                  (ii) dividends, interest, or other Distributions hereafter
            paid or payable in cash in respect of any Collateral in connection
            with a partial or total liquidation or dissolution, or in connection
            with a reduction of capital, capital surplus, or paid-in-surplus;

                  (iii) cash paid, payable, or otherwise distributed in
            redemption of, or in exchange for, any Collateral; and

                  (iv) dividends, interest, or other Distributions paid or
            payable in violation of the Loan Documents,

      shall be part of the Collateral hereunder, shall, if received by Debtor,
      be held in trust for the benefit of Secured Party, and shall forthwith be
      delivered to Secured Party (accompanied by proper instruments of
      assignment and/or stock and/or bond powers executed by Debtor in
      accordance with Secured Party's instructions) to be held subject to the
      terms of this Pledge Agreement. Any cash proceeds of Collateral which come
      into the possession of Secured Party (including, without limitation,
      insurance proceeds) may, at Secured Party's option, be applied in whole or
      in part to the Obligation (to the extent then due), be released in whole
      or in part to or on the written instructions of Debtor for any general or
      specific purpose, or be retained in whole or in part by Secured Party as
      additional Collateral. Any cash Collateral in the possession of Secured
      Party may be invested by Secured Party in certificates of deposit issued
      by Secured Party (if Secured Party issues such

<PAGE>

      certificates) or by any state or national bank having combined capital and
      surplus greater than $100,000,000 with a rating from Moody's and S&P of
      P-1 and A-1+, respectively, or in securities issued or guaranteed by the
      United States of America or any agency thereof. Secured Party shall never
      be obligated to make any such investment and shall never have any
      liability to Debtor for any loss which may result therefrom. All interest
      and other amounts earned from any investment of Collateral may be dealt
      with by Secured Party in the same manner as other cash Collateral. The
      provisions of this subparagraph are applicable whether or not a Default or
      Potential Default exists.

            (f) Power of Attorney. Debtor hereby irrevocably constitutes and
      appoints Secured Party as Debtor's attorney-in-fact, with full irrevocable
      power and authority in the place and stead of Debtor and in the name of
      Debtor, Secured Party, Lenders, or otherwise, from time to time in Secured
      Party's discretion, for the sole purpose of carrying out the terms of this
      Pledge Agreement and, to the extent permitted by applicable Law, to take
      any action and to execute any document and instrument which Secured Party
      may deem necessary or advisable to accomplish the following when a Default
      exists:

                  (i) to receive, endorse, and collect any drafts or other
            instruments or documents in connection with clause (b) above and
            this clause (f); and

                  (ii) to execute on behalf of Debtor, any financing statement
            or continuation statement with respect to the Security Interests
            created hereby which Secured Party may deem necessary or advisable
            to protect and preserve the Collateral, and all Rights thereto, when
            a Default exists.

            (g) Purchase Money Collateral. To the extent that Secured Party or
      any Lender has advanced or will advance funds to or for the account of
      Debtor to enable Debtor to purchase or otherwise acquire Rights in
      Collateral, Secured Party or such Lender, at its option, may pay such
      funds (i) directly to the Person from whom Debtor will make such purchase
      or acquire such Rights, or (ii) to Debtor, in which case Debtor covenants
      to promptly pay the same to such Person, and forthwith furnish to Secured
      Party evidence satisfactory to Secured Party that such payment has been
      made from the funds so provided.

            (h) Subrogation. If any of the Obligation is given in renewal or
      extension or applied toward the payment of indebtedness secured by any
      Lien, Secured Party shall be, and is hereby, subrogated to all of the
      Rights, titles, interests, and Liens securing the indebtedness so renewed,
      extended, or paid.

            (i) Indemnification. Debtor hereby assumes all liability for the
      Collateral, for the Security Interest, and for any use or possession of,
      all or any of the Collateral, including, without limitation, any Taxes
      arising as a result of, or in connection with, the transactions
      contemplated herein, and agrees to assume liability for, and to indemnify
      and hold Secured Party and each Lender harmless from and against, any and
      all claims, causes of action, or liability, howsoever arising, from or
      incident to such use or possession, whether such Persons be agents or
      employees of Debtor or of third parties. Debtor agrees to indemnify, save,
      and hold Secured Party and each Lender harmless from and against, and
      covenants to defend Secured Party and each Lender against, any and all
      losses, damages, claims, costs, penalties, liabilities, and expenses
      (collectively, "Claims"), including, without limitation, court costs and
      attorneys' fees, and any of the foregoing arising from the negligence of
      Secured Party or any Lender, or any of their respective officers,
      employees, agents, advisors, employees, or representatives, howsoever
      arising or incurred because of, incident to, or with respect to Collateral
      or any use or possession thereof; provided, however, that the indemnity
      set forth

<PAGE>

      in this Paragraph 8(i) will not apply to Claims caused by the gross
      negligence or willful misconduct of Secured Party or any Lender.

      9. ACKNOWLEDGMENT OF REGULATORY CONSIDERATIONS

            (a) No Prohibited Transfers. It is hereby acknowledged that
      assignment or transfer of control of Authorization without the prior
      approval of Governmental Authorities may constitute a prohibited transfer
      in violation of Law. Secured Party agrees that exercise of its Rights
      hereunder shall be effected only after the obtaining of any necessary
      approvals for such exercise.

            (b) Actions by Debtor. If counsel to Secured Party reasonably
      determines that the consent of any Governmental Authority is required in
      connection with any of the actions which may be taken by Secured Party on
      behalf of the Lenders in the exercise of their Rights hereunder or under
      the Loan Documents, then Debtor, at its sole cost and expense, agrees to
      use its best efforts to secure such consent and to cooperate with Secured
      Party and Lenders in any action commenced by Secured Party to secure such
      consent. Upon the occurrence and during the continuation of a Default or
      Potential Default, Debtor shall promptly execute or cause the execution of
      all applications, certificates, instruments, and other documents and
      papers that the Secured Party may be required to file in order to obtain
      any necessary governmental consent, approval, or authorization, and if
      Debtor fails or refuses to execute such documents, then, on the order of
      any court of competent jurisdiction, the Clerk of the Court with
      jurisdiction may execute such documents on behalf of Debtor. Debtor
      further recognizes that a violation of this covenant would result in
      irreparable harm to Lenders for which monetary damages are not readily
      ascertainable and which might not fully compensate such Lenders.
      Therefore, in addition to any other remedy which may be available to the
      Lenders, at Law or in equity, Secured Party on behalf of Lenders shall
      have the remedy of specific performance of the provisions of this
      subsection.

            (c) Approval of Governmental Authorities. Notwithstanding anything
      to the contrary contained in this Pledge Agreement, Secured Party will not
      take any action pursuant to this Pledge Agreement or any of the documents
      executed pursuant hereto which would constitute an assignment of an
      Authorization or any transfer of control of an Authorization if such
      assignment of license or transfer of control would require under
      then-existing Law (including the written rules and regulations promulgated
      by any Governmental Authority) the prior approval of the Governmental
      Authority issuing such Authorization, without first obtaining such
      approval. Debtor agrees to take, or cause to be taken, any action which
      Secured Party may reasonably request in order to obtain and enjoy the full
      Rights and benefits granted to Secured Party by this Pledge Agreement and
      any other instruments or agreements executed pursuant hereto, including,
      without limitation, at Debtor's cost and expense, the exercise of its best
      efforts to cooperate in obtaining Governmental Authority approval of any
      action or transaction contemplated by this Pledge Agreement or any other
      instrument or agreement executed pursuant hereto which is then required by
      Law.

            (d) Subsequent Actions by Debtor. Debtor agrees that if, for any
      reason, any Governmental Authority does not approve within a reasonable
      period of time the initial application for approval of the transfer of the
      Authorizations, then Paragraphs 9(b) and (c) above hereof shall be
      applicable to any subsequent application for transfer of the
      Authorizations pursuant to action taken by Secured Party in the exercise
      of its Rights hereunder or under the Loan Documents. With respect to each
      subsequent proposed purchaser(s), Debtor agrees to execute all such
      applications and other documents and take all such other action as may be
      reasonably requested by Secured Party at any time and from time to time in
      order to obtain the approval by the Governmental Authorities.

<PAGE>

      Exercise by Secured Party of the Right to such cooperation shall not be
      exhausted by the initial or any subsequent exercise thereof.

      10. MISCELLANEOUS.

            (a) Continuing Security Interest. This Pledge Agreement creates a
      continuing security interest in the Collateral and shall (i) remain in
      full force and effect until the termination of the obligations of the
      Lenders to advance Borrowings or issue LCs under the Loan Documents, the
      payment in full of the Obligation, and the expiration of all LCs and
      Financial Hedges issued by any Lender or any Affiliate of any Lender to
      Debtor or any Company; (ii) be binding upon Debtor, its successors, and
      assigns; and (iii) inure to the benefit of and be enforceable by the
      Secured Party, Lenders, and their respective successors, transferees, and
      assigns. Without limiting the generality of the foregoing clause (iii),
      the Secured Party and Lenders may assign or otherwise transfer any of
      their respective Rights under this Pledge Agreement to any other Person in
      accordance with the terms and provisions of Section 13.13 of the Credit
      Agreement, and to the extent of such assignment or transfer such Person
      shall thereupon become vested with all the Rights and benefits in respect
      thereof granted herein or otherwise to the Secured Party or the Lenders,
      as the case may be. Upon payment in full of the Obligation, the
      termination of the commitment of Lenders to extend credit or issue LCs,
      and the expiration of all LCs or Financial Hedges issued by any Lender or
      any Affiliate of any Lender to Debtor or any Company, Debtor shall be
      entitled to the return, upon its request and at its expense, of such of
      the Collateral as shall not have been sold or otherwise applied pursuant
      to the terms hereof.

            (b) Reference to Miscellaneous Provisions. This Pledge Agreement is
      one of the "Loan Documents" referred to in the Credit Agreement, and all
      provisions relating to Loan Documents set forth in Section 13 of the
      Credit Agreement, other than the provisions set forth in Section 13.7, are
      incorporated herein by reference, the same as if set forth herein
      verbatim.

            (c) Term. Upon full and final payment and performance of the
      Obligation, this Pledge Agreement shall thereafter terminate upon receipt
      by Secured Party of Debtor's written notice of such termination; provided
      that no Obligor, if any, on any of the Collateral shall ever be obligated
      to make inquiry as to the termination of this Pledge Agreement, but shall
      be fully protected in making payment directly to Secured Party until
      actual notice of such total payment of the Obligation is received by such
      Obligor.

            (d) Actions Not Releases. The Security Interest and Debtor's
      obligations and Secured Party's Rights hereunder shall not be released,
      diminished, impaired, or adversely affected by the occurrence of any one
      or more of the following events: (i) the taking or accepting of any other
      security or assurance for any or all of the Obligation; (ii) any release,
      surrender, exchange, subordination, or loss of any security or assurance
      at any time existing in connection with any or all of the Obligation;
      (iii) the modification of, amendment to, or waiver of compliance with any
      terms of any of the other Loan Documents without the notification or
      consent of Debtor, except as required therein (the Right to such
      notification or consent being herein specifically waived by Debtor); (iv)
      the insolvency, bankruptcy, or lack of corporate or trust power of any
      party at any time liable for the payment of any or all of the Obligation,
      whether now existing or hereafter occurring; (v) any renewal, extension,
      or rearrangement of the payment of any or all of the Obligation, either
      with or without notice to or consent of Debtor, or any adjustment,
      indulgence, forbearance, or compromise that may be granted or given by
      Secured Party or any Lender to Debtor; (vi) any neglect, delay, omission,
      failure, or refusal of Secured Party or any Lender to take or prosecute
      any action in connection with any other agreement, document, guaranty, or
      instrument evidencing, securing, or

<PAGE>

      assuring the payment of all or any of the Obligation; (vii) any failure of
      Secured Party or any Lender to notify Debtor of any renewal, extension, or
      assignment of the Obligation or any part thereof, or the release of any
      security, or of any other action taken or refrained from being taken by
      Secured Party or any Lender against Debtor or any new agreement between or
      among Secured Party or one or more Lenders and Debtor, it being understood
      that neither Secured Party nor any Lender shall be required to give Debtor
      any notice of any kind under any circumstances whatsoever with respect to
      or in connection with the Obligation, including, without limitation,
      notice of acceptance of this Pledge Agreement or any Collateral ever
      delivered to or for the account of Secured Party hereunder; (viii) the
      illegality, invalidity, or unenforceability of all or any part of the
      Obligation against any party obligated with respect thereto by reason of
      the fact that the Obligation, or the interest paid or payable with respect
      thereto, exceeds the amount permitted by Law, the act of creating the
      Obligation, or any part thereof, is ultra vires, or the officers,
      partners, or trustees creating same acted in excess of their authority, or
      for any other reason; or (ix) if any payment by any party obligated with
      respect thereto is held to constitute a preference under applicable Laws
      or for any other reason Secured Party or any Lender is required to refund
      such payment or pay the amount thereof to someone else.

            (e) Waivers. Except to the extent expressly otherwise provided
      herein or in other Loan Documents and to the fullest extent permitted by
      applicable Law, Debtor waives (i) any Right to require Secured Party or
      any Lender to proceed against any other Person, to exhaust its Rights in
      Collateral, or to pursue any other Right which Secured Party or any Lender
      may have; (ii) with respect to the Obligation, presentment and demand for
      payment, protest, notice of protest and nonpayment, and notice of the
      intention to accelerate; and (iii) all Rights of marshaling in respect of
      any and all of the Collateral.

            (f) Financing Statement. Secured Party shall be entitled at any time
      to file this Pledge Agreement or a carbon, photographic, or other
      reproduction of this Pledge Agreement, as a financing statement, but the
      failure of Secured Party to do so shall not impair the validity or
      enforceability of this Pledge Agreement.

            (g) Amendments. This Pledge Agreement may be amended only by an
      instrument in writing executed jointly by Debtor and Secured Party, and
      supplemented only by documents delivered or to be delivered in accordance
      with the express terms hereof.

            (h) Multiple Counterparts. This Pledge Agreement has been executed
      in a number of identical counterparts, each of which shall be deemed an
      original for all purposes and all of which constitute, collectively, one
      agreement; but, in making proof of this Pledge Agreement, it shall not be
      necessary to produce or account for more than one such counterpart.

            (i) Parties Bound; Assignment. This Pledge Agreement shall be
      binding on Debtor and Debtor's heirs, legal representatives, successors,
      and assigns and shall inure to the benefit of Secured Party and Secured
      Party's successors and assigns.

                  (i) Secured Party is the agent for each Lender under the
            Credit Agreement, the Security Interest and all Rights granted to
            Secured Party hereunder or in connection herewith are for the
            ratable benefit of each Lender, and Secured Party may, without the
            joinder of any Lender, exercise any and all Rights in favor of
            Secured Party or Lenders hereunder, including, without limitation,
            conducting any foreclosure sales hereunder, and executing full or
            partial releases hereof, amendments or modifications hereto, or
            consents or waivers hereunder. The Rights of each Lender vis-a-vis
            Secured Party and each other Lender may

<PAGE>

            be subject to one or more separate agreements between or among such
            parties, but Debtor need not inquire about any such agreement or be
            subject to any terms thereof unless Debtor specifically joins
            therein; and consequently, neither Debtor nor Debtor's heirs,
            personal representatives, successors, and assigns shall be entitled
            to any benefits or provisions of any such separate agreements or be
            entitled to rely upon or raise as a defense, in any manner
            whatsoever, the failure or refusal of any party thereto to comply
            with the provisions thereof.

                  (ii) Debtor may not, without the prior written consent of
            Secured Party, assign any Rights, duties, or obligations hereunder.

            (j) GOVERNING LAW. PURSUANT TO SECTION 5-1401 OF THE NEW YORK
      GENERAL OBLIGATIONS LAW, THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK
      APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH
      STATE, WITHOUT REGARD TO THE CHOICE OF LAW PRINCIPLES THAT MIGHT OTHERWISE
      APPLY, EXCEPT TO THE EXTENT THE LAWS OF ANOTHER JURISDICTION GOVERN THE
      CREATION, PERFECTION, VALIDITY, OR ENFORCEMENT OF LIENS UNDER THE PLEDGE
      AGREEMENT, AND THE APPLICABLE FEDERAL LAWS OF THE UNITED STATES OF
      AMERICA, SHALL GOVERN THE VALIDITY, CONSTRUCTION, ENFORCEMENT AND
      INTERPRETATION OF THIS PLEDGE AGREEMENT AND ALL OF THE OTHER LOAN
      DOCUMENTS.

Loan Documents as of the Effective Date equal to the percentage interest
specified on Schedule 1 of all outstanding Rights and obligations with respect

Debt (for each Facility or Discretionary Loan, as appropriate) of Assignee and
Assignor after giving effect to this Assignment and Acceptance Agreement.

enter into this Assignment and Acceptance Agreement; (b) confirms that it has

Acceptance Agreement; (c) agrees that it will, independently and without
reliance upon Administrative Agent, Assignor, or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
the Credit Agreement; (d) confirms that it is an Eligible Assignee; (e) appoints
and authorizes Administrative Agent to take such action as Administrative Agent
on its behalf and to exercise such powers and discretion under the Credit
Agreement as are delegated to Administrative Agent by the terms thereof,
together with such powers and discretion as are reasonably incidental thereto;
(f) agrees that it will perform in accordance with their terms all of the

<PAGE>

obligations that by the terms of the Credit Agreement are required to be
performed by it as a Lender; and (g) attaches any U.S. Internal Revenue Service
or other forms required under Section 4.6(d) of the Credit Agreement.

      4. Following the execution of this Assignment and Acceptance Agreement by
Assignor, Assignee, and Borrower (to the extent required hereunder), it will be
delivered to Administrative Agent for acceptance and recording by Administrative
Agent pursuant to the Credit Agreement. The effective date for this Assignment
and Acceptance Agreement shall be the date described on Schedule 1 (the
"Effective Date"), which shall not, unless otherwise agreed to by Administrative
Agent in its sole discretion, be earlier than five Business Days from the date
of such acceptance and recording by Administrative Agent.

      5. Upon such acceptance and recording by Administrative Agent, as of the
Effective Date, (a) Assignee shall be a party to the Credit Agreement and, to
the extent provided in this Assignment and Acceptance Agreement, have the Rights
and obligations of a Lender thereunder, and (b) Assignor shall, to the extent
provided in this Assignment and Acceptance Agreement, relinquish its Rights and
be released from its obligations under the Agreement.

      6. Upon such acceptance and recording by Administrative Agent, from and
after the Effective Date, Administrative Agent shall make all payments under the
Credit Agreement, the Notes (to the extent any of the Principal Debt owed to
Assignee is evidenced by Notes), and loan accounts in respect of the interest
assigned hereby (including, without limitation, all payments of principal,
interest, and commitment fees and other fees with respect thereto) to Assignee.
Assignor and Assignee shall make all appropriate adjustments in payments under
the Credit Agreement and the other Loan Documents for periods prior to the
Effective Date directly between themselves.

      7. Unless Assignee is a Lender, an Affiliate of Assignor, or an Approved
Fund of Assignor, this Assignment and Acceptance Agreement is conditioned upon
the consent of Administrative Agent and, unless a Default or Potential Default
then exists, Borrower, pursuant to the definition of "Eligible Assignee" in the
Credit Agreement. The execution and delivery of this Assignment and Acceptance
Agreement by Borrower and Administrative Agent is evidence of this consent.

      8. As contemplated by Section 13.13(b)(iv) of the Credit Agreement,
Assignor or Assignee (as determined between Assignor and Assignee) agrees to pay
to Administrative Agent for its account on the Effective Date in federal funds a
processing fee of $3,500.

      9. THIS ASSIGNMENT AND ACCEPTANCE AGREEMENT SHALL BE GOVERNED BY, AND
SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS.

      10. This Assignment and Acceptance Agreement may be executed in any number
of counterparts and by different parties hereto in separate counterparts, each
of which when so executed shall be deemed to be an original and all of which
taken together shall constitute one and the same agreement. Delivery of an
executed counterpart of Schedule 1 to this Assignment and Acceptance Agreement
by telecopier shall be effective as delivery of a manually executed counterpart
of this Assignment and Acceptance Agreement.

      IN WITNESS WHEREOF, Assignor and Assignee have caused Schedule 1 to this
Assignment and Acceptance Agreement to be executed by their officers thereunto
duly authorized as of the date specified thereon.

                     FORM OF OPINION OF COUNSEL OF BORROWER
                           (Dobson Operating Company)

                                [Firm Letterhead]

January 18, 2000

Bank of America, N.A., as Administrative Agent
Each Lender named in Schedule 2.1 to the Credit Agreement referred to below

Re:   Credit Agreement for Dobson Operating Co., L.L.C.

Ladies and Gentlemen:

      We have acted as counsel to Dobson Communications Corporation
("Communications"), Dobson Operating Co., L.L.C. (successor by merger with
Dobson Operating Company and Dobson Cellular Operations Company) ("Borrower"),
and certain other entities affiliated with Communications and the Borrower
identified on Annex A hereto (collectively with Borrower, the "Companies") in
connection with (i) the Amended, Restated, and Consolidated Revolving Credit and
Term Loan Agreement, dated as of January 18, 2000 (as amended, modified,
supplemented, or restated from time to time, the "Credit Agreement"), among
Borrower, Bank of America, N.A., as Administrative Agent, and Lenders named on
Schedule 2.1 to the Credit Agreement ("Lenders") and (ii) the Reorganization (as
defined in the Credit Agreement). Such entities, the respective states in which
each is organized and the respective states (other than its state of
organization) in which each is qualified to do business are identified on Annex
A hereto.

      This opinion is delivered pursuant to Section 7.1 of the Credit Agreement
and Paragraph 11 of Schedule 7.1 to the Credit Agreement. Except as otherwise
defined herein, each capitalized term used herein has the meaning given to such
term in the Credit Agreement.

      In arriving at the opinions expressed below, we have examined such
corporate documents and records of Communications and the Companies and such
certificates of public officials and of officers of Communications and the
Companies, other documents, and matters of law as we deemed necessary or
appropriate, including, without limitation, originals or copies of (a) the
Credit Agreement, (b) the Notes, (c) the Guaranties, (d) the Pledge, Assignment,
and Security Agreements executed by Borrower and the Companies, (e) the Pledge,
Assignment, and Security Agreements executed by Communications (collectively
with (d) above, the "Security Agreements"), (f) Financing Statements showing
Communications and the Companies, as Debtors, and Administrative Agent, as
Secured Party, to be filed in appropriate jurisdictions; and (g) other
Collateral Documents (all of the foregoing are collectively, the "Transaction
Documents"); additionally, we have examined the Agreement of Merger among Dobson
Cellular Systems, Inc., Dobson Operating Company, Dobson Operating Co., L.L.C.
and various affiliated companies dated January 10, 2000 and certificates
reflecting the transactions described in such agreement prepared for filing in
appropriate state offices (the "Reorganization Documents").

      Based upon the foregoing, we are of the opinion that:

      1. The Borrower (a) is a limited liability company validly existing and in
good standing under the Laws of Oklahoma and (b) possesses all requisite
authority and power to execute, deliver, and comply with the terms of each of
the Transaction Documents and the Reorganization Documents to which it is a

<PAGE>

party, which have been duly authorized and approved by all necessary limited
liability company action and for which no approval or consent of any Person or
Governmental Authority is required which has not been obtained. Each Company
which is a corporation and Communications (a) is a corporation validly existing
and in good standing under the Laws of the state of its organization, (b) is
duly qualified to transact business as a foreign corporation in each other state
identified on Annex A, and (c) possesses all requisite corporate authority and
power to execute, deliver, and comply with the terms of each of the Transaction
Documents and the Reorganization Documents to which it is a party, which have
been duly authorized and approved by all necessary corporate action and for
which no approval or consent of any Person or Governmental Authority is required
which has not been obtained. Each Company which is a general partnership (a) is
a general partnership validly existing and in good standing under the Laws of
the state of its organization, and (b) possesses all requisite authority and
power to execute, deliver, and comply with the terms of each of the Transaction
Documents to which it is a party, which have been duly authorized and approved
by all necessary partnership action and for which no approval or consent of any
Person or Governmental Authority is required which has not been obtained. Each
Company which is a limited partnership (a) is a limited partnership validly
existing and in good standing under the Laws of the state of its organization,
and (b) possesses all requisite authority and power to execute, deliver, and
comply with the terms of each of the Transaction Documents to which it is a
party, which have been duly authorized and approved by all necessary partnership
action and for which no approval or consent of any Person or Governmental
Authority is required which has not been obtained.

      2. Communications and each Company has duly executed and delivered each
Transaction Document and each Reorganization Document to which it is a party.

      3. The execution, delivery, and performance of and compliance with the
terms of the Transaction Documents and the Reorganization Documents will not
cause the Borrower to be in violation of its Operating Agreement or Articles of
Organization. The execution, delivery, and performance of and compliance with
the terms of the Transaction Documents and the Reorganization Documents will not
cause Communications or any Company which is a corporation to be in violation of
its respective Articles or Certificates of Incorporation or Bylaws. The
execution, delivery, and performance of and compliance with the terms of the
Transaction Documents will not cause any Company which is a partnership to be in
violation of its respective partnership agreement or, as to limited
partnerships, its Certificate of Limited Partnership.

      4. Following the Consummation of all transactions described in the
Transaction Documents (including the closing of Term Loan A and the Deposit with
U.S. Trust Company, as Indenture Trustee, of funds required to pay certain notes
issued by Communications, as reflected in the letter from Indenture Trustee to
Communications dated January 18, 2000, all as described therein) Communications
will not be in violation of the Certificates of Designation relating to the
respective issues of its Preferred Stock or of the agreements governing the
Communications Bond Debt.

      5. The execution, delivery, and performance of and compliance with the
terms of the Transaction Documents and the Reorganization Documents will not
cause Communications or any Company to be in violation of any Laws other than
such violations which will not, individually or collectively, be a Material
Adverse Event.

      6. The execution, delivery, and performance of and compliance with the
terms of the Transaction Documents and the Reorganization Documents will not
cause Communications or any Company to be in default under any of the Material
Agreements described in Schedule 8.15 of the Credit Agreement.

      7. To our knowledge there is no alleged violation by Communications or any
Company of any applicable Laws, federal, state, and local (including without
limitation, Environmental Laws and those

<PAGE>

statutes administered by each state public utility commission that, on the date
of this opinion, exercises jurisdiction over Communications and the Companies
(collectively, the "Local Authorities")), which, if determined adversely, would
be material to the conduct of its business and operations. Except as have been
obtained, no authorization, consent, approval, waiver, licenses, or formal
exemptions from, nor any filing, declaration, or registration with, any
Governmental Authority or non-governmental entity, under the terms of the
contracts or otherwise, is required by reason of or in connection with the
execution and performance of the Transaction Documents and the Reorganization
Documents. To our knowledge, the consummation of each of the Reorganization, the
tender offer for the Communications Bond Debt and the transactions contemplated
by the Transaction Documents in the manner therein contemplated is not
restrained by any decree, judgment, ruling or injunction.

      8. To our knowledge, there is no pending Litigation against Communications
or any Company which, if determined adversely to Communications or such Company,
would be material to the conduct of its business or operations.

      9. Subject to the qualifications set forth below, the choice of New York
law in the Transaction Documents would be upheld by an Oklahoma court. However,
if an Oklahoma court determined that the Transaction Documents were to be
governed by Oklahoma law notwithstanding the parties' choice of New York law,
the Transaction Documents would constitute the valid and binding obligations of
Communications and each Company which is a party thereto, enforceable against
such parties in accordance with their respective terms.

      10. The Persons pledging to Administrative Agent, for the benefit of
Lenders, any of the Pledged Securities (as defined in the Security Agreements)
are the record owners thereof, free and clear of any restrictions or, to our
knowledge, any encumbrances. The Pledged Securities comprise 100% of the
membership interests in Borrower, 100% of the capital stock of Dobson Cellular
Systems, Inc. and 86.4% of the capital stock of Santa Cruz Cellular Telephone,
Inc.

      11. The Financing Statements are in sufficient form for recordation under
the Uniform Commercial Code as adopted in Oklahoma. When the Financing
Statements have been filed and recorded in accordance with applicable Laws of
the jurisdictions listed on Annex A hereto, no further action, including any
filing or recording of any document, is necessary in order to establish and
perfect Lenders' security interests created by the Security Agreements in the
assets described in the financing statements, to the extent the same may be
perfected by the filing of financing statements under the applicable laws of
such jurisdiction. No further action is required under Oklahoma law in order to
maintain the perfection of such security interests other than the periodic
filing of continuation statements with respect to financing statements filed
under the Oklahoma Uniform Commercial Code.

      12. The Reorganization Documents have been duly executed and delivered by
all parties thereto, and constitute the valid and legally binding obligations of
such parties, enforceable in accordance with their terms, except as the
enforcement may be limited by Debtor Relief Laws and except that the remedies
available with respect thereto may be subject to general principles of equity
(regardless of whether such remedies are sought in a proceeding in equity or at
law). The Reorganization has been consummated in accordance with the
Reorganization Documents and applicable Law.

      The foregoing opinions are subject to the following qualifications,
assumptions and exceptions:

      (a) Our opinions are limited to matters governed by Laws of the state of
Oklahoma and applicable federal law. We express no opinion on matters governed
by the Laws of other states. Accordingly, our opinions in paragraph 1 above, to
the extent governed by Laws other than the Laws of

<PAGE>

Oklahoma, are (i) based solely on our review of the organizational documents of
such Companies and certificates of good standing issued by Secretaries of State
of such states and (ii) are based on the assumption that the Laws of such states
are, as to matters addressed in paragraph 1 above, substantially similar to the
Laws of Oklahoma . Our opinions as to the qualification and good standing of the
entities described in paragraph 1 and the consummation of the Reorganization are
based on the certificates of the Secretaries of State of the applicable
jurisdictions or, in some cases, confirmation of certain filings with such
Secretaries of State by CT Corporation. Further, we express no opinion as to (i)
the validity, binding effect or enforceability of the Transaction Documents
under New York law, as such matters are addressed in the separate opinion of
this date issued to you by Edwards & Angell, LLP (and we have relied on such
opinion in certain of the opinions expressed above) or (ii) certain regulatory
matters, as such matters are addressed in the separate opinion of this date
issued to you by Wilkinson, Barker, Knauer & Quinn.

      (b) We express no opinion on title to or the relative priority of liens or
encumbrances on any property described in the Transaction Documents.

      (c) We have assumed that the principal place of business and chief
executive office of Communications and each Company is in the state of Oklahoma.
Further, we have assumed that neither Communications nor any Company has assets
which serve as Collateral under the Security Agreements other than in the states
in which they are organized or qualified to conduct business, as identified on
Annex A hereto.

      (d) Section 162 of Title 15 of the Oklahoma Statutes provides as follows:

            "A contract is to be interpreted according to the law and usage of
            the place where it is to be performed, or, if it does not indicate a
            place of performance, according to the law and usage of the place
            where it is made."

In addition to the general choice of law rule stated in the aforementioned
statute, Section 1-105 of Title 12A of the Oklahoma Statutes provides as
follows:

            "(1) Except as provided hereafter in this section, when a
            transaction bears a reasonable relation to this state and also to
            another state or nation, the parties may agree that the law either
            of this state or of such other state or nation shall govern their
            rights and duties. . . ."

Oklahoma courts have held, in cases construing choice of law provisions in
promissory notes and other contracts, that an express provision by the parties
designating a place of performance or providing a specific choice of law will be
given effect unless to give it effect would violate the public policy of the
State of Oklahoma. While there is no controlling authority, we believe that,
based on the decisions regarding promissory notes and other contracts, an
Oklahoma court should give effect to the choice of law provisions contained in
the Transaction Documents so long as Oklahoma public policy is not violated.

      The enforceability of obligations under any of the Transaction Documents
is subject to (i) bankruptcy, insolvency, reorganization, moratorium and similar
laws affecting the rights and remedies of creditors generally or the application
of principles of equity, whether in an action in law or proceeding in equity;
(ii) the requirement under the Uniform Commercial Code that a secured party
exercise its rights in a commercially reasonable manner, (iii) public policy
considerations which may limit the right to obtain certain remedies and to
indemnification; (iv) fraudulent transfer and conveyance laws; and (v)
applicable limitations on creation of encumbrances on, and transfers of,
licenses. Moreover, a court may fail or refuse to enforce provisions of
agreements or documents if the enforcement thereof is based upon defaults or

<PAGE>

breaches which are immaterially to the ultimate performance contemplated
thereby. No opinion is expressed as to the legality, validity, or enforceability
of any waiver of the right to receive notice, any waiver of any legal or
equitable defense, any waiver of equity, redemption, stay or appraisal, any
waiver of the availability of specific performance, injunctive relief or other
equitable remedies, or any other waiver, including, without limitation, any
waiver as to trial by jury. Finally, certain provisions of the Transaction
Documents may be unenforceable or their enforceability limited, but such
unenforceability or limitation on enforceability will not impair the practical
realization of the rights of the Lenders under the Transaction Documents.

      (e) Our opinion in paragraph 10 as to the Pledged Securities is based
solely on our review of the corporate stock records provided by Communications
and the Companies and certificates of officers of such entities.

      (f) We have assumed the authenticity of all documents submitted to us as
originals, the conformity with the originals of all documents submitted to us as
copies and the genuineness of all signatures on documents we have reviewed.

      This opinion is addressed to you solely for your use in connection with
the transactions contemplated by the Transaction Documents, and no person other
than Administrative Agent, each Lender, each assignee that hereafter becomes a
Lender as permitted by the Credit Agreement, and the law firm of Haynes and
Boone, LLP, is entitled to rely hereon without our prior written consent. This
opinion is given as of the date hereof, and we have no obligation to revise or
update this opinion subsequent to the date hereof or to advise you or any other
person of any matter subsequent to the date hereof which would cause us to
modify this opinion in whole or in part.

                                        Very truly yours,

                                        ________________________________________

                       FORM OF OPINION OF NEW YORK COUNSEL

                                January __, 2000

Bank of America, N.A., as Administrative Agent
Bank of America Plaza
901 Main Street
Dallas, Texas 75202

And the Lenders party to the Revolving Credit and Term Loan Agreement referred
to below

      Re:   Amended, Restated and Consolidated Revolving Credit and Term Loan
            Agreement, dated as of January 14, 2000 (the "Revolving Credit and
            Term Loan Agreement"), between Dobson Operating Company, LLC, the
            several banks and other financial institutions from time to time
            parties thereto (the "Lenders"), and Bank of America, N.A. in its
            capacity as administrative agent for the Lenders (the
            "Administrative Agent")

Ladies and Gentlemen:

      We have acted as special New York counsel to Dobson Operating Company,
LLC, an Oklahoma corporation (the "Borrower"), solely in connection with the
preparation, execution and delivery of the Revolving Credit and Term Loan
Agreement and certain of the ancillary documents appended thereto as Exhibits.
This opinion is being delivered pursuant to Section 7.1 of the Revolving Credit
and Term Loan Agreement and Paragraph 13 of Schedule 7.1 thereto. Capitalized
terms used but not otherwise defined herein are defined as set forth in the
Revolving Credit and Term Loan Agreement.

      In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of the Revolving Credit
and Term Loan Agreement and the ancillary documents executed as of the date
hereof in the forms attached as Exhibits A-1, A-2, A-3, A-4, A-5, A-6, A-7, C,
D-1, D-2, F and H thereto (collectively, the "Loan Documents").

      We have assumed (i) that all signatures on documents examined by us are
genuine, (ii) the due authorization, execution and delivery of each Loan
Document by each party thereto, (iii) that each party is duly incorporated or
organized, validly existing and in good standing under the laws of its
jurisdiction of formation, (iv) that each Loan Document constitutes a valid and
binding obligation of each party thereto, (v) the legal capacity of all parties
to the Loan Documents, (vi) the authenticity of all documents submitted to us as
originals and (vii) the conformity to original documents of all documents
submitted to us as certified, conformed or photostatic copies and the
authenticity of the originals of such copies.

      We are qualified to practice law in the State of New York and we do not
purport to express any opinion herein concerning any law other than the law of
the State of New York.

      Based on the foregoing, and subject to the qualifications and assumptions
stated herein, we are of the opinion that each Loan Document to which the
Borrower or any Guarantor is a party is enforceable against the Borrower or any
Guarantor, as the case may be, in accordance with its terms.

<PAGE>

      Limitations and Qualifications

      This opinion is also subject to the following further limitations,
assumptions and qualifications:

      (a) No opinion is expressed as to (i) the location of, or sufficiency of
the description of, any of the Collateral, (ii) the ownership of, or legal or
equitable title to, any property, (iii) any real property or the legality,
validity or enforceability of any mortgage agreement or document relating
thereto, (iv) any Intellectual Property or the grant of any rights therein or
the validity thereof, (v) the priority of any security interest in any
Collateral or (vi) the perfection of any security interest in any Collateral.

      (b) The enforceability of obligations under any agreement or document with
respect to which we have opined is subject to (i) bankruptcy, insolvency,
reorganization, moratorium and similar laws affecting the rights and remedies of
creditors generally or the application of principles of equity, whether in an
action in law or proceeding in equity; (ii) the requirement under the UCC that a
secured party exercise its rights in a commercially reasonable manner, (iii)
public policy considerations which may limit the right to obtain certain
remedies and to indemnification; and (iv) fraudulent transfer and conveyance
laws. Moreover, a court may fail or refuse to enforce provisions of agreements
or documents if the enforcement thereof is based upon defaults or breaches which
are immaterial to the ultimate performance contemplated thereby.

      (c) No opinion is expressed as to the legality, validity, or
enforceability of any waiver of the right to receive notice, any waiver of any
legal or equitable defense, any waiver of equity, redemption, stay or appraisal,
any waiver of the availability of specific performance, injunctive relief or
other equitable remedies, or any other waiver, including, without limitation,
any waiver as to trial by jury.

      This opinion is solely for the benefit of the Administrative Agent and the
Lenders and is solely for their benefit in connection with the transactions
contemplated by the Revolving Credit and Term Loan Agreement. Without our
express written consent, this opinion may not be relied upon in any manner by
any other person or for any other purpose by the Administrative Agent or the
Lenders. This opinion is not to be referred to or quoted in any document, report
or financial statement, or filed with, or delivered to, any governmental agency
or other person or entity, except such disclosure as may be required by law,
without our prior written consent in each instance.

      This opinion is given as of the date hereof and we disclaim any duty or
obligation to advise you of any factual or legal changes of which we become
aware after the date hereof. This opinion is limited to the matters stated
herein and no opinion shall be implied or inferred beyond the matters expressly
stated.

                                        Very truly yours,

                                        EDWARDS & ANGELL, LLP

                                   EXHIBIT G-3

                  FORM OF OPINION OF SPECIAL REGULATORY COUNSEL

                                January 18, 2000

Bank of America, N.A., as Administrative Agent
901 Main Street
64th Floor
Dallas, TX 75202

Each Lender Named in Schedule 2.1 to the Credit Agreement referred to below

      Re:   Amended, Restated and Consolidated Revolving Credit and Term Loan
            Agreement (the "Credit Agreement"), dated as of January 18, 2000,
            among Dobson Operating Co. L.L.C., Borrower; Banc of America
            Securities, LLC, as Sole Lead Arranger and Book Running Manager;
            Banc of America, N.A., as Administrative Agent, Lehman Commercial
            Paper Inc. and Toronto Dominion (Texas), Inc., as Co-Syndication
            Agents; and First Union National Bank and PNC Bank, National
            Association, as Co-Documentation Agents; the Managing Agents and
            Co-Agents defined therein; and the Lenders named in Schedule 2.1,
            thereof.

Ladies and Gentlemen:

      We have acted as special communications counsel to Dobson Operating Co.,
LLC (successor by merger with Dobson Operating Company and Dobson Cellular
Operations Company) ("Borrower"), and its Restricted Subsidiaries (collectively
with Borrower, the "Companies", and individually, a Company). The Companies have
requested that we deliver this letter to you in connection with the execution
and delivery of the Credit Agreement, and of the Notes and Collateral Documents
dated as of January 18, 2000, executed by the Companies (collectively the "Loan
Documents"), pursuant to which Lenders have agreed to provide three credit
facilities totaling $800,000,000, in the form of a revolving loan facility in
the aggregate principal amount of $300,000,00, and two term loan facilities in
the aggregate principal amount of $500,000,000 to the Company. This opinion is
being delivered to you pursuant to Section 7.1 and paragraph 13 of Schedule 7.1
of the Credit Agreement. Capitalized terms used herein which are not otherwise
defined shall have the meanings assigned to them in the Loan Documents.

      We have examined the Loan Documents, the Reorganization Documents, the
licenses and certificates of public convenience and necessity and similar
authorizations issued to the Companies by the Federal Communications Commission
("FCC") and any state public utility commission ("PUC") that, on the date of
this opinion, exercises jurisdiction over the Companies (each such PUC, an
"Applicable PUC"). Schedule I lists the states in which Applicable PUCs exist as
of the date of this opinion. Our opinion is limited to the provisions of the
Communications Act of 1934 as amended, 47 U.S.C. ss.151 et seq., and all rules,
regulations, and published policies of the FCC (collectively, the
"Communications Act"), and all rules, regulations, and published policies of and
all laws administered by the Applicable PUCs (the "PUC Laws"), and we express no
opinion and assume no responsibility as to the applicability of any other laws.

      We have assumed the genuineness of signatures of all persons signing any
documents, the authority of all persons signing any document on behalf of
parties thereto, the authority of all public officials and governmental
authorities, the authenticity of all documents submitted to us as originals, the
conformity to

<PAGE>

authentic originals of all documents submitted to us as copies, and the
correctness of public files, records and certificates of, or furnished by,
governmental or regulatory agencies or authorities.

      This opinion is based upon our examination of the rules, regulations,
documents, certificates, public files and records of the FCC, and our
examination of the Loan Documents. As to any facts material to these opinions
which we did not establish by relying upon documents or records, we have relied
upon statements, representations and/or certificates of officers, directors,
principals, or agents of the Company made in any of the Loan Documents, or in
originals or copies of files in our office (certified or otherwise identified to
our satisfaction). No other investigation has been undertaken in connection with
this opinion, and in particular, we have made no independent audit of any of the
Companies' operations. To the extent that certain factual matters are stated "to
the best of our knowledge," or a similar phrase, it is intended to indicate that
those attorneys in this firm who have rendered legal services to the Companies
on a regular basis do not have current actual knowledge of the inaccuracy of
such statement. However, except as otherwise expressly indicated, we have not
undertaken any independent investigation to determine the accuracy of any such
statement, and no inference that we have any knowledge of any matters pertaining
to such statement should be drawn from our representation of the Company.

      Determinations as to the de facto control of an FCC licensee are made by
the FCC on a case-by-case basis. Our opinion assumes that the covenants and
conditions contained in the Loan Documents will be exercised and/or enforced in
a commercially reasonable manner.

      Members of our firm are admitted to the bar of the District of Columbia.
While members of our firm are admitted to the bars of other states in which any
of the Companies may be operating, we hold no opinions with respect to the laws
in those states that are implicated, if any, by the transactions herein, except
for the laws of any Applicable PUC. Further, we express no opinion as to any
other federal laws or the laws or rules of any other jurisdiction, state, county
or municipal, except, as applicable, the Communications Act.

      In rendering our opinions herein, we have relied solely upon the
information described explicitly above, and on no other information. We disclaim
any responsibility or duty to investigate, ascertain or report on any document,
matter, condition or proceeding which is outside the scope of our review
described in this letter, or which may develop subsequently to the date of this
letter, including any amendments or revisions to any of the Loan Documents made
after the date hereof. This disclaimer includes, but is not limited to, judicial
proceedings involving other parties (such as antitrust proceedings in the
communications industry), legislative proceedings, rulemaking proceedings before
the FCC, the PUC or other agencies, and official or informal proceedings which
are not a matter of written public record (such as investigations, confidential
deliberations, and the like).

      We disclaim any responsibility or duty to conduct any further
investigation of the matters addressed herein after the date of this letter. If
we subsequently become aware of any change in the information in this letter, we
disclaim any duty or responsibility to bring it to your attention or to the
attention of your counsel.

      Based upon the foregoing, we are of the opinion that:

      1. The consummation of the Reorganization and the execution and delivery
of the Credit Agreement and the other Loan Documents by Borrower, and the
performance by each of the Companies of its obligations thereunder will not
violate any law, rule, regulation, or policy of the FCC or any Applicable PUC.

<PAGE>

      2. The execution and delivery of a Guaranty and other Collateral Documents
by the Restricted Subsidiaries party thereto and the performance by such
Restricted Subsidiaries of their respective obligations thereunder will not
violate any law, rule, regulation, or policy of the FCC or any Applicable PUC.

      3. Each Company holds all licenses required by the FCC and all other
certificates or licenses required by any Applicable PUC for the construction and
the operation (as to the best of our knowledge, such cellular systems are being
operated) of each of the cellular systems owned or leased by that Company
(collectively, the "Cellular Systems"), except where such failure would not
materially affect such Company's business or operations, taken as a whole. All
such certificates and licenses are duly and validly held by the applicable
Company, and all such certificates and licenses are in full force and effect
without conditions, other than such conditions that are generally applicable to
such licenses and other certificates.

      4. The Companies' execution and delivery, and performance and compliance
with the terms and provisions of the Credit Agreement and the other Loan
Documents and the Reorganization Documents: (a) will not result in a violation
of the Communications Act or any PUC Laws: (b) will not cause any cancellation,
termination, revocation, forfeiture, or material impairment of any FCC or PUC
authorization, certificate, or license; and (c) will not require further notice
to or the approval of the FCC or any Applicable PUC, except in the states where
applications for authority are currently pending, and except that
post-consummation notice of the consummation of the Reorganization will be
required by the FCC and several of the Applicable PUCs.

      5. To the best of our knowledge, the ownership and operation by the
Companies of the Cellular Systems are in compliance in all material respects
with the Communications Act (including, without limitation, all FCC filing,
reporting, prior approval, and similar requirements).

      6. No approval, authorization, consent, adjudication, or order of the FCC
or any Applicable PUC which has not been obtained by the Companies as of this
date is required to be obtained by the Companies, in connection with the
consummation of the Reorganization, the execution and delivery of the Loan
Documents, the borrowing under the Credit Agreement, the payment or performance
of the Obligations by the Companies or the creations of the Liens in favor of
Lenders under the Loan Documents.

      7. To the best of our knowledge: (a) there is no outstanding decree or
order that has been issued by the FCC or any Applicable PUC against any Company
and no pending or threatened litigation, proceedings, notice of violation, order
to show cause, complaints, inquiry, or investigation before the FCC or any
Applicable PUC (i) relating to any Company or relating to its Systems or
business operations that might result in the cancellation, termination,
revocation, forfeiture, or material impairment of any FCC or PUC authorizations,
certificates, or licenses, or have any material adverse effect upon, or cause
material disruption to, any Company or the ownership or operation of such
Systems or business operations or (ii) seeking to prohibit, restrict, or delay
consummation of the transactions contemplated by the Loan Documents, the
Reorganization Documents, or fulfillment of any conditions under the Loan
Documents or the Reorganization Documents; and (b) no action has been taken by
the FCC or any Applicable PUC which might now, or after notice or lapse of time,
or both, result in the cancellation, termination, revocation, forfeiture, or
material impairment of any FCC or PUC authorizations, certificates, or licenses,
or have any material adverse effect upon, or material disruption to, any Company
or the ownership or operation of their Systems or business operations.

      In rendering the opinions in this letter, we are engaged in acting solely
as counsel for the Company, and we are not engaged or acting as counsel for the
any of the Lenders, the Administrative Agent or any other person or entity. This
opinion letter is provided to Administrative Agent, each Lender, and Haynes and
Boone, LLC, and their respective participants, assignees, or other transferees,
by us in our capacity as special

<PAGE>

communications regulatory counsel to the Companies and can be relied upon, on a
confidential basis in connection with the transactions contemplated by the Loan
Documents solely by such persons. This opinion may not be relied upon by any
other person or for any other purpose except with the prior written consent of
the undersigned. This letter is provided to you on the condition that its
contents are not disclosed to any other person or entity, except as stated in
this paragraph. This opinion is not to be quoted in whole or in part or
otherwise referred to in any document except as directly a part of and related
to the transactions contemplated under the Loan Documents and, except as
required by applicable law, not to be filed with any governmental authority or
any other entity or person whatsoever.

                                        Sincerely,

                                        WILKINSON BARKER KNAUER, LLP

                    FORM OF AFFILIATE SUBORDINATION AGREEMENT

      THIS AFFILIATE SUBORDINATION AGREEMENT is entered into among Bank of
America, N.A., in its capacity as Administrative Agent for Lenders (defined
below), and ___________________, a __________________ ___________ ("Subordinated
Creditor"), and Dobson Operating Co., L.L.C. (successor by merger with Dobson
Operating Company and Dobson Cellular Operations Company, "Borrower").

      WHEREAS, Borrower, Bank of America, N.A., as Administrative Agent, and
certain Lenders have entered into an Amended, Restated, and Consolidated
Revolving Credit and Term Loan Agreement, dated as of January 18, 2000 (as
amended, modified, supplemented, or restated from time to time, the "Credit
Agreement");

      WHEREAS, this Agreement is integral to the transactions contemplated by
the Loan Documents, and the execution and delivery thereof is a condition
precedent to Lenders' obligations to extend credit under the Loan Documents;

      NOW, THEREFORE, for valuable consideration, the receipt and adequacy of
which are hereby acknowledged, Administrative Agent, Subordinated Creditor, and
Borrower agree as follows:

      1. Unless otherwise defined herein, or the context hereof otherwise
requires, each term defined in the Credit Agreement is used in this Agreement
with the same meaning. As used herein, the following terms have the meanings
indicated:

            Senior Debt means, whether now or hereafter arising, the Obligation,
      including, without limitation, interest thereon after the commencement of
      any proceedings under any Debtor Relief Law.

            Subordinated Debt means the principal of and interest on all Debt of
      Borrower or any other Company, whether direct, indirect, fixed,
      contingent, liquidated, unliquidated, joint, several, or joint and
      several, now or hereafter existing, due, or to become due to Subordinated
      Creditor, or held or to be held by Subordinated Creditor, whether created
      directly or acquired by assignment or otherwise, and whether evidenced by
      written instrument or not.

      2. The payment of any and all Subordinated Debt is hereby expressly
subordinated to all Senior Debt to the extent and in the manner set forth in
this Agreement.

      3. Subordinated Creditor shall not accelerate, demand, sue for, commence
any collection or enforcement action or proceeding, take, receive, accept, or
retain any payment or distribution of any character, whether in cash,
securities, or other property, in respect of the principal of, premium on, or
interest on, the Subordinated Debt, or any Collateral therefor, until all Senior
Debt shall have been paid in full with interest, including, without limitation,
interest during any bankruptcy or similar proceeding involving Borrower from the
date of the filing thereof to the date of distribution (notwithstanding any
statute, including without limitation the Federal Bankruptcy Code, any rule of
Law, or bankruptcy procedures to the contrary).

      4. In the event of the institution of and in connection with any
proceeding against Borrower pursuant to any Debtor Relief Law, and unless or
until the Senior Debt is paid in full:

<PAGE>

            (a) All Senior Debt shall first be paid in full before any payment
      or distribution of any character, whether in cash, securities, or other
      property, shall be made in respect of any Subordinated Debt;

            (b) Any payment or distribution of any character, whether in cash,
      securities, or other property, which would otherwise (but for the terms
      hereof) be payable or deliverable in respect of any Subordinated Debt,
      shall be paid or delivered directly to Administrative Agent, for the
      benefit of Lenders, until all Senior Debt shall have been paid in full,
      and Subordinated Creditor irrevocably authorizes, empowers, and directs
      all receivers, trustees, liquidators, conservators, and others having
      authority to effect all such payments and deliveries;

            (c) Administrative Agent, on behalf of Lenders, may, as
      attorney-in-fact for Subordinated Creditor, take such action on behalf of
      Subordinated Creditor, and Subordinated Creditor hereby appoints
      Administrative Agent, on behalf of Lenders, as its attorney-in-fact, to
      demand, sue for, collect, and receive any and all such moneys, dividends,
      or other assets and give acquittance therefor and to file any claim, proof
      of claim, or other instrument of similar character and to take such other
      proceedings in the name of Subordinated Creditor as Administrative Agent
      may deem necessary or advisable for the enforcement of this Agreement; and

            (d) Each Subordinated Creditor shall execute and deliver to
      Administrative Agent, for the benefit of Lenders, all such further
      instruments confirming the authorization referred to in the foregoing
      clauses (b) and (c) and all such proofs of claim, assignments of claim,
      and other instruments and shall take all such other actions as may be
      requested by Administrative Agent in order to enable Administrative Agent
      to enforce all Rights of Lenders and Administrative Agent hereunder and
      all claims of Administrative Agent or any Lender upon or in respect of the
      Subordinated Debt, and failing execution of such instruments or taking of
      such actions by Subordinated Creditor, Administrative Agent, for the
      benefit of Lenders, is hereby authorized and empowered to execute and
      perform the same on behalf of such Subordinated Creditor.

      5. In the event any payment or distribution of any character, whether in
cash, securities, or other property, is received by Subordinated Creditor in
contravention of the terms of this Agreement, and before all Senior Debt shall
have been paid in full, such payment or distribution shall be held by such
Subordinated Creditor, as trustee of an express trust, in trust for the benefit
of, and shall be paid over or delivered and transferred to Administrative Agent
for application to all Senior Debt remaining unpaid until such Senior Debt shall
have been paid in full. Each Subordinated Creditor hereby assigns to
Administrative Agent, for the benefit of Lenders, all its Rights to any such
payments or distributions, which Administrative Agent may exercise in
Administrative Agent's name or in the name of such Subordinated Creditor, and
agrees to execute such instruments as may be required by Administrative Agent to
enable Administrative Agent, for the benefit of Lenders, to enforce such claims.
Any payments or distributions received in excess of the amount sufficient to pay
all Senior Debt in full shall be returned by Administrative Agent to such
Subordinated Creditor.

      6. Administrative Agent or Lenders may, at any time and from time to time,
without the consent of or notice to Subordinated Creditor, without incurring
responsibility to Subordinated Creditor, and without impairing or releasing any
of Administrative Agent's Rights, or any of the obligations of Subordinated
Creditor hereunder, (a) change the amount, manner, place, or terms of payment,
or change or extend the time of payment of or renew or alter all or any part of
the Senior Debt or amend, modify, supplement, or restate, any of the Loan
Documents in any manner whatsoever; (b) sell, exchange, release, or otherwise
deal with all or any part of any property by whomsoever at any time pledged or
mortgaged to secure, or howsoever securing, all or any part of the Senior Debt;
(c) hold all or any Property as additional Collateral under the

<PAGE>

Loan Documents to secure all or any part of the Senior Debt; (d) release anyone
liable in any manner for the payment or collection of all or any part of the
Senior Debt; (e) exercise or refrain from exercising any Rights against Borrower
and others (including the undersigned); and (f) apply any sums, by whomsoever
paid or however realized, to the Senior Debt.

      7. Notwithstanding anything to the contrary contained in any other
instrument or document delivered in connection with the Subordinated Debt or
otherwise, including, without limitation, any prior perfection of a security
interest or Lien, any security interests and Liens now or hereafter held by
Subordinated Creditor in any Collateral for the Subordinated Debt shall be
junior and subordinate to any security interests and Liens now or hereafter held
by Administrative Agent, for the benefit of Lenders, in the same Collateral. So
long as the Senior Debt shall remain unpaid, Administrative Agent may at all
times in its sole discretion exercise any and all powers and Rights which it now
has or may hereafter acquire with respect to any of the Collateral securing the
Senior Debt, all without the necessity of obtaining any consent or approval of
Subordinated Creditor.

      8. Each Subordinated Creditor represents and warrants that it is duly
organized, validly existing, and in good standing under the laws of its state of
organization and has the power and authority under the laws of such state and
under its articles of incorporation and by-laws or other organizational
documents to enter into this Agreement; all actions necessary or appropriate for
its execution and performance of this Agreement have been taken and upon its
execution, this Agreement will constitute its valid and binding obligation
enforceable in accordance with its terms; and the making and performance of this
Agreement will not violate any law or its articles of incorporation or by-laws
or other organizational documents, or result in any violation of or constitute a
default under any agreement by which it or any of its property is bound.

      9. This Agreement is a continuing agreement of subordination and Lenders
may continue to make loans to or otherwise accept the obligations of Borrower in
reliance hereon, without notice to Subordinated Creditor.

      10. While this Agreement remains in effect, each Subordinated Creditor
covenants and agrees that it will not modify or amend or permit modification or
amendment of the terms and conditions of the Subordinated Debt, without
obtaining the prior written consent of Administrative Agent.

      11. No waiver of Administrative Agent's Rights hereunder shall be
effective unless in a writing signed by Administrative Agent, and each waiver
shall extend only to the specific instance involved and shall not impair or
affect Administrative Agent's Rights in any other respect at any other time.
Each Subordinated Creditor hereby waives all notices with respect to the subject
matter hereof, including, but not limited to, notice of acceptance of this
Agreement, of the making of loans or advances to the Borrower or any extensions,
renewals, or modifications thereof, releases of collateral security or
guarantors or other indulgences of any character, or of the occurrence or
declaration of any default or the taking of any collection or enforcement
action. This Agreement shall be governed by and construed according to the Laws
of the State of New York.

      12. This Agreement inures to the benefit of Administrative Agent, Lenders,
and their respective successors and assigns, and the Rights under this Agreement
may be assigned in whole or in part in connection with any partial or complete
assignment or transfer of the Senior Debt. Administrative Agent is
Administrative Agent for each Lender, and Administrative Agent may, without the
joinder of any Lender, exercise any and all Rights in favor of Lenders
hereunder. The Rights of each Lender vis-a-vis Administrative Agent and each
other Lender may be subject to one or more separate agreements between or among
such parties, but Subordinated Creditor need not inquire about any such
agreement or be subject to

<PAGE>

any terms thereof unless Subordinated Creditor specifically joins therein; and,
consequently, neither Subordinated Creditor nor its heirs, personal
representatives, successors, or assigns are entitled to any benefits or
provisions of any such separate agreements or are entitled to rely upon or raise
as a defense, in any manner whatsoever, the failure or refusal of any party
thereto to comply with the provisions thereof. This Agreement binds Subordinated
Creditor and its successors and assigns, and Subordinated Creditor will advise
each future holder of all or any part of the Subordinated Debt that the
Subordinated Debt is subordinated to the Senior Debt in the manner and to the
extent set forth in this Agreement.

      13. This Agreement may be executed in a number of identical counterparts,
each of which is deemed an original for all purposes and all of which
constitute, collectively, one agreement; but, in making proof of this Agreement,
it is not necessary to produce or account for more than one counterpart.

      14. Subject to the provisions of this Agreement and the Rights of
Administrative Agent hereunder, as between Borrower and Subordinated Creditor,
nothing herein contained shall impair the obligation of Borrower, which is
absolute and unconditional to pay the Subordinated Debt as and when the same
shall become due and payable in accordance with the terms thereof, or prevent
Subordinated Creditor upon default with respect to the Subordinated Debt, from
exercising all rights, powers, and remedies otherwise provided therein or by
applicable Law.

                                    AMENDMENT

                                     TO THE

                         1997 EQUITY PARTICIPATION PLAN

                                       OF

                               GUITAR CENTER, INC.

     Pursuant to the authority reserved to the Board of Directors (the "BOARD")
of Guitar Center, Inc., a corporation organized under the laws of State of
Delaware (the "COMPANY"), under Section 10.2 of the 1997 Equity Participation
Plan of Guitar Center, Inc. (the "PLAN"), the Board hereby amends the Plan as
follows.

          1.   The definition of "Award Limit" is amended to read in its
entirety as follows:

          "'Award Limit'" shall mean 250,000 shares of Common Stock.

          2.   The first sentence of the definition of "Option" is amended to
read in its entirety as follows:

          "'Option' shall mean a stock option granted under Article III or
     Article IIIA of this Plan."

          3.   The second sentence of Section 2.1(a) of the Plan is amended to
read in its entirety as follows:

          "The aggregate number of such shares which may be issued upon exercise
     of such options or rights or upon any such awards under the Plan shall not
     exceed two million, seven hundred twenty-five thousand (2,725,000)."

          4.   Section 3.4(b) of the Plan is amended to read in its entirety as
follows:

         "(b)  Upon the selection of a key Employee, consultant or Independent
Director to be granted an Option, the Committee (or the Board, with respect to
an Option granted to an Independent Director) shall instruct the Secretary of
the Company to issue the Option and may impose such conditions on the grant of
the Option as it deems appropriate. Without limiting the generality of the
preceding sentence, (x) the Board may, in its discretion and on such terms as it
deems appropriate, provide that an Option granted to any Independent Director
shall be in addition or in lieu of an Option that may be or has been granted to
such Independent Director pursuant to Section 3.4(d) or Article IIIA hereof, or
(y) the

<PAGE>

Committee (or the Board, with respect to an Option granted to an Independent
Director) may, in its discretion and on such terms as it deems appropriate,
require as a condition on the grant of an Option to an Employee, consultant or
Independent Director that the Employee, consultant or Independent Director
surrender for cancellation some or all of the unexercised Options, awards of
Restricted Stock or Deferred Stock, Performance Awards, Stock Appreciation
Rights, Dividend Equivalents or Stock Payments or other rights which have been
previously granted to him under this Plan or otherwise. An Option, the grant of
which is conditioned upon such surrender, may have an option price equal to,
higher or lower than the exercise price of such surrendered Option or other
award, may cover the same (or a lesser or greater) number of shares as such
surrendered Option or other award, may contain such other terms as the Committee
(or the Board, with respect to an Option granted to an Independent Director)
deems appropriate, and shall be exercisable in accordance with its terms,
without regard to the number of shares, exercise period or any other term or
condition of such surrendered Option or other award."

          5.   The second sentence of Section 3.1 is hereby amended to read in
its entirety as follows:

          "Each Independent Director of the Company shall be eligible to be
     granted Options at the times and in the manner set forth in Section
     3.4(a)(i), 3.4(d) or Article IIIA."

          6.   Article IIIA is hereby added to the Plan to read in its entirety
as follows:

                                  "ARTICLE IIIA

                       INDEPENDENT DIRECTOR OPTION PROGRAM

          3.1A GRANTING OF ADDITIONAL OPTIONS.

          (a)  In addition to those Options referenced in Section 3.4(d), during
each 12-month (or shorter) period commencing on the date of the Company's annual
stockholders' meeting (each, a "PLAN YEAR") in which a person is an Independent
Director and is entitled to receive the Retainer (as defined below) during the
term of the Plan, each such Independent Director may elect to receive all or any
portion of his or her Retainer either (i) in cash or (ii) in the form of an
Option (an "ADDITIONAL OPTION"), with the exercise price of such Option to be as
set forth in Section 3.2A, below (the "ELECTION"). The number of shares of
Common Stock subject to such Additional Option shall be equal to a fraction
(rounded to the nearest whole number), with the numerator of such fraction equal
to the Retainer and denominator of such fraction equal to the product of (i)
fifteen one-hundredths (0.15) and (ii) the Fair Market Value of a share of
Common Stock as of the date of grant of such Additional Option. Each Additional
Option shall

                                       2
<PAGE>

be granted in one or more installments on the same date(s) on which all or any
portion of the Retainer would otherwise have been paid if it were paid in cash
(with such date referred to as the "date of grant"). For purposes of this Plan,
"Retainer" shall mean the amount of compensation (including, without limitation,
annual Director fees, committee fees and meeting fees) set by the Board from
time to time as payable to a Director in each Plan Year.

          (b)  The Election described in Section 3.1A(a) must be made by written
notice provided by the Independent Director to the Committee no later than the
last day of the Plan Year immediately preceding the Plan Year with respect to
which such Election is intended to be effective; PROVIDED, HOWEVER, that no
Election shall be effective with respect to any portion of the Retainer
attributable to services rendered prior to the date of filing of such Election.
An Election shall be irrevocable with respect to the Plan Year for which it is
made, and shall remain in effect for a subsequent Plan Year unless revoked by
written notice provided by the Independent Director to the Committee prior to
the first day of such subsequent Plan Year.

          3.2A ADDITIONAL OPTION TERMS. Notwithstanding anything in Article IV
to the contrary, with respect to any Additional Option granted pursuant to
Section 3.1A, the exercise price of each share of Common Stock subject to such
Additional Option shall be equal to the product of (i) the Fair Market Value of
a share of Common Stock subject to such Additional Option (determined as of the
date of grant of such Additional Option) and (ii) eighty-five one-hundredths
(0.85); the term of such Additional Option shall be ten (10) years from the date
the Additional Option is granted, except as may be amended by the Committee in
its discretion; and such Additional Option shall be fully exercisable as of the
date the Additional Option is granted.

          7.   This Amendment shall be submitted for approval at the annual
meeting of stockholders of the Company scheduled to be held on May 2, 2000, or
any postponement or adjournment thereof. The provisions of this Amendment shall
be presented to the stockholders severally in such format as shall be approved
by the Secretary of the Corporation and may be considered and approved or
disapproved by the stockholders independently in the format approved by the
Secretary, except that paragraph 6 relating to the "Independent Director Option
Plan" shall not be deemed approved unless the increase in authorized shares
contemplated by paragraph 3 is approved.
