                           any bankruptcy, reorganization or insolvency
                           proceeding or (vi) take corporate action for the
                           purpose of effecting any of the foregoing; or (i) an
                           involuntary petition or complaint is filed against
                           Debtor seeking bankruptcy or reorganization of
                           Debtor, or the appointment of a receiver, custodian,
                           trustee, intervenor or liquidator for Debtor, or for
                           all or substantially all of Debtor's assets, and such
                           petition or complaint is not dismissed within 60 days
                           of the filing thereof, or (ii) an order, judgment or
                           decree shall be entered by any Tribunal approving a
                           petition or complaint seeking reorganization of
                           Debtor or appointing a receiver, custodian, trustee,
                           intervenor or liquidator for Debtor, or of all or
                           substantially all of Debtor's assets, as applicable,
                           and such order, judgment or decree continues unstayed
                           for a period of 60 days.

                    (ix)   Any "Event of Default" occurs under the Security
                           Agreement dated as of May 29, 2001 between Logix
                           Communications Corporation and the Secured Party, as
                           amended, modified or supplemented from time to time.

                     (x)   This Pledge Agreement shall cease for any reason to
                           be in full force and effect, or the Debtor shall so
                           assert, or the lien or security interest created
                           under this Pledge Agreement shall cease to be
                           enforceable and of the same effect and priority
                           purported to be created hereunder.

6.       REMEDIES.

           6.1    Upon the occurrence of an Event of Default and at any time
                  thereafter, Secured Party may without notice to Debtor declare
                  all liabilities secured hereby immediately due and payable,
                  and may proceed to enforce payment and performance of same and
                  exercise any and all rights and remedies provided by the
                  Uniform Commercial Code, as well as all other rights and
                  remedies possessed by Secured Party. Unless the Collateral in
                  whole or in part threatens to decline speedily in value or is
                  of a type customarily sold on a recognized market, Secured
                  Party will give the Debtor reasonable notice of the time and
                  place of any public sale, or of the time after which any
                  private sale or other disposition is to be made. The Secured
                  Party may be a purchaser at any public sale. The requirement
                  of reasonable notice shall be met if notice is mailed, postage
                  prepaid, to the address of the Debtor provided for herein at
                  least ten (10) days before sale or other disposition. The
                  Secured Party is authorized at any such sale, if it deems it
                  advisable to do so, to restrict prospective bidders or
                  purchasers to persons 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 the Collateral.
                  Secured Party is also hereby authorized by Debtor, but not
                  obligated, to take such actions, give such notices, obtain
                  such rulings and consents, and do such other

                                       6
<Page>

                  things as Secured Party may deem appropriate in the event of a
                  sale or disposition of any of the Collateral. Debtor clearly
                  understands that Secured Party may in its discretion approach
                  a restricted number of potential purchasers and that a sale
                  under such circumstances may yield a lower price for the
                  Collateral or any part or parts thereof than would otherwise
                  be obtainable if sold in the open market, and Debtor agrees
                  that such private sales shall constitute a commercially
                  reasonable method of disposing of the Collateral.

           6.2    As regards that portion of the Collateral consisting of cash
                  or cash equivalent items such as checks, drafts or deposited
                  funds, Secured Party may upon the occurrence of an Event of
                  Default specified in Section 5 hereof, immediately apply them
                  against any liabilities of the Debtor, selected by Secured
                  Party, and for this purpose it is agreed that cash or
                  equivalents will be considered identical to cash proceeds.
                  Secured Party shall have the right immediately and without
                  further action by it to set off against the liabilities
                  secured hereby all money owed by Secured Party to the
                  undersigned whether due or not, and Secured Party will be
                  deemed to have exercised such right of set off and to have
                  made a charge against such money at the time of any
                  acceleration upon default even though some charges made are
                  entered on the Secured Party's books subsequent thereto.
                  Secured Party may demand, collect, receipt for, settle,
                  compromise, adjust, sue for, foreclose, release or realize
                  upon the Collateral, in its own name or in the name of Debtor
                  as Secured Party may determine. Secured Party shall not be
                  liable for any act or omission on the part of Secured Party,
                  its officers, agents, or employees, except willful misconduct.

           6.3    As regards that portion of the Collateral consisting of stock
                  or other voting securities, the Secured Party may upon the
                  occurrence of an Event of Default hereunder:

                    (i)    Transfer to or register in its name or in the name of
                           its nominee any of the Collateral, with or without
                           indication of the security interest herein created,
                           and whether or not so transferred or registered,
                           receive the income, dividends and other distributions
                           thereon and hold them or apply them to the
                           liabilities of the Debtor, in any order of priority;

                   (ii)    Exercise or cause to be exercised all voting and
                           corporate powers with respect to any of the
                           Collateral so registered or transferred, including
                           all rights of conversion, exchange, subscription or
                           any other rights, privilege or options pertaining to
                           such collateral, as if the absolute owner thereof,
                           and the Debtor hereby irrevocably grants to the
                           Secured Party the Debtor's proxy to vote any
                           Collateral during any Event of Default and the Debtor
                           shall take action which the Secured Party may request
                           in furtherance of the granting of such proxy; the
                           proxy granted and each stock power and similar power
                           now or hereafter granted are coupled within interest
                           and shall be irrevocable;

                                       7
<Page>

                  (iii)    Make any compromise or settlement deemed advisable
                           with respect to any of the Collateral; or

                   (iv)    Renew, extend or otherwise change the terms and
                           conditions of any of the Collateral.

                    (v)    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
                           Collateral 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, to sell all or
                           any part of the Collateral at private sale, subject
                           to investment letter or in any other manner which
                           will not require the Collateral, or any part thereof,
                           to be registered in accordance with the Securities
                           Act or any other laws or regulations. 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 Collateral, or any part thereof,
                           than would otherwise be obtainable if such Collateral
                           were either afforded to a larger number of potential
                           purchasers, registered under the Securities Act, or
                           sold in the open market. Debtor agrees that any such
                           private sale made under this Agreement 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 Collateral to permit the issuer
                           thereof to register it for public sale under any
                           applicable federal or state securities Laws.

                   (vi)    Secured Party is authorized, in connection with any
                           such sale, (A) to restrict the prospective bidders on
                           or purchasers of any of the Collateral 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 Collateral, 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
                           Collateral so sold. Each purchaser at any such sale
                           shall hold the Collateral 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.

                                       8
<Page>

                  (vii)    The Collateral may be sold in one lot as an entirety
                           or in separate parcels, as Secured Party may
                           reasonably determine.

                 (viii)    So long as no Event of Default shall have occurred or
                           exist, the Debtor shall have all voting or other
                           consensual rights with respect to the Collateral;
                           PROVIDED, HOWEVER, that the Debtor shall not exercise
                           or refrain from exercising any such right without the
                           consent of the Secured Party if such action or
                           inaction could result in a material reduction in the
                           fair market value of the Collateral, or adversely
                           affect (A) the validity, priority or perfection of
                           the first priority security interest and pledge
                           granted or purported to be granted hereunder or (B)
                           the rights and remedies of the Secured Party
                           hereunder.

7.       GENERAL.

         7.1      FURTHER ASSURANCES. Debtor agrees to promptly execute such
                  stock powers, endorse such instruments, or execute such
                  additional pledge agreements or other documents as may be
                  required by the Secured Party in order effectively to grant to
                  Secured Party the security interest in (and pledge and
                  assignment of) the Collateral and to enforce and exercise
                  Secured Party's rights regarding same.

         7.2      SECURITIES LAWS. Upon the occurrence or existence of an Event
                  of Default, Debtor hereby agrees to cooperate fully with
                  Secured Party to sell, at foreclosure or other private sale,
                  the Collateral pledged hereunder.

         7.3      EXPENDITURES OF SECURED PARTY. The Debtor shall be liable for
                  and agrees to pay Secured Party for all expenditures of
                  Secured Party in maintaining the Collateral, and all costs,
                  attorney's fees and other expenditures of Secured Party in the
                  enforcement or collection of any note, warranty, agreement,
                  liability or obligation of the Debtor, to Secured Party or in
                  the enforcement or collection of or realization upon the
                  Collateral or in the holding, preparing for sale or sale of
                  any Collateral.

         7.4      WAIVERS. No act, delay, omission, or course of dealing between
                  the Debtor and Secured Party, including Secured Party's waiver
                  of remedy because of any default hereunder, shall constitute a
                  waiver of any of Secured Party's rights and remedies under
                  this Agreement or any other agreement between the parties, or
                  under the documents evidencing the liabilities secured hereby.
                  Waiver by Secured Party of any rights or remedies under the
                  terms of this Agreement or with respect to any of Debtor's
                  liabilities to Secured Party will not be a bar to the exercise
                  of any right or remedy on any subsequent occasion. All rights
                  and remedies of Secured Party are cumulative and may be
                  exercised singularly or concurrently, and the exercise of any
                  one or more of them will not be a waiver of any other. No
                  waiver, change, modification, or discharge of any of Secured
                  Party's rights or of the Debtor's duties as so specified or
                  allowed will be effective unless in writing and signed by
                  Secured Party.

         7.5      SECURED PARTY'S RIGHT TO TRANSFER. Debtor grants to Secured
                  Party the right to transfer any and all of the Collateral to
                  its own name or that of its nominee after default, and Secured
                  Party may exercise all rights and privileges to which it will
                  thereupon become entitled, but it will be under no duty to
                  exercise such rights and privileges.

         7.6      RIGHTS OF SECURED PARTY ASSIGNABLE. Secured Party at any time
                  and at its option may pledge, transfer or assign its rights
                  under this Agreement or any part of said rights, and any
                  pledgee, transferee or assignee shall have the rights of
                  Secured Party as to the rights or parts thereof so pledged,
                  transferred or assigned.

         7.7      PARTIAL INVALIDITY. If any provision of this Agreement shall

                                PROMISSORY NOTE

$2,000,000                                               Oklahoma City, Oklahoma
                                                                    May 29, 2001

     FOR VALUE RECEIVED, the undersigned, LOGIX COMMUNICATIONS ENTERPRISES, INC.
(the "Borrower") on or before June 30, 2003, hereby unconditionally promises to
pay to the order of DOBSON CC LIMITED PARTNERSHIP (the "Lender") at 14201
Wireless Way, Oklahoma City, Oklahoma, 73134, in lawful money of the United
States of America, the principal sum of Two Million and 00/100 Dollars
($2,000,000), or so much thereof as shall have been advanced hereunder and
remains unpaid, together with interest thereon as hereinafter provided.

     Interest from the date hereof on the unpaid principal balance of this
Promissory Note ("Note") shall accrue and be due and payable quarterly,
commencing on the 30th day of September, 2001, and on the last day of each and
every December, March, June and September thereafter and at maturity. All
payments made under this Note shall be made to the Lender by 12 noon, central
time, and applied first to the interest then accrued and then to the reduction
of the unpaid principal balance hereof.

     The unpaid principal balance hereof outstanding from time to time shall
bear interest (computed on the basis of 360 days in the year), at a rate per
annum which shall from day-to-day be equal to the lesser of: (i) two percent
(2.0%) in excess of the Prime Rate, or (ii) the Maximum Rate. Each change in the
rate charged hereunder, subject to the terms hereof, becomes effective without
notice to the Borrower, upon the effective date of each change in Prime Rate, or
the Maximum Rate, as the case may be. As used herein, the term "Maximum Rate"
means the maximum rate of interest from time-to-time which the Lender is allowed
to contract for, charge for, take, reserve or receive under applicable law,
after taking into account, to the extent required by applicable law, any and all
relevant payments or charges hereunder and the term "Prime Rate" shall mean the
highest rate of interest expressed as a percentage as published from time to
time as the "Prime Rate" in the "Money Rates" section of THE WALL STREET
JOURNAL, SOUTHWEST EDITION. Each determination by Lender of an interest rate or
an amount of interest that is due and payable by Borrower shall be conclusive
and binding on Borrower absent manifest error.

     Any sum not paid when due shall bear interest from the date of default at
the rate equal to fourteen percent (14%) per annum, accrued from the date of
default until paid. During the existence of any default, the Lender may apply
payments received on any amount due hereunder or under the terms of any
instrument now or hereafter evidencing or securing the indebtedness evidenced by
this Note as the Lender may determine.

     The Borrower agrees that if, and as often as, this Note is placed in the
hands of an attorney for collection or to defend or enforce any of the Lender's
rights hereunder or under any instrument securing payment of this Note, the
Borrower will pay to the holder hereof its attorney's fees and all court costs
and other expenses incurred in connection therewith.

<PAGE>

     This Note is secured by a Pledge and Security Agreement (the "Pledge
Agreement") dated as of May 29, 2001 executed by Borrower in favor of Lender,
covering shares of capital stock of Dobson Telephone Company, Inc., Logix
Communications Corporation, and Dobson Fiber/Forre of Colorado, Inc., the
proceeds from the sale of all or any of such shares of capital stock, and
certain other assets of Borrower. This Note and such Pledge Agreement will be
referred to herein as the "Loan Documents."

     The terms, provisions and conditions of the Loan Documents are incorporated
herein by reference as if set forth in full herein, provided that, in the event
of any ambiguity as between the Note and the Loan Documents, this Note shall
control.

     Upon the breach of any provision of the Loan Documents, or any other
instrument securing payment of this Note, or an Event of Default as defined in
the Pledge Agreement, at the option of the Lender, following any notice and/or
grace period set forth in the Loan Documents the entire unpaid indebtedness
evidenced by this Note will become due, payable and collectable immediately or
at such time thereafter as the Lender hereof may elect. Notice of the exercise
of such option is hereby expressly waived. Failure of the Lender hereof to
exercise such option will not constitute a waiver of the right to exercise the
same.

     This Note is given by Borrower and accepted by Lender hereof pursuant to
the lending transaction contracted, negotiated, consummated and to be performed
in Oklahoma City, Oklahoma County, Oklahoma, and this Note is to be construed
according to the laws of the State of Oklahoma. All loan proceeds advanced and
to be advanced under this Note are solely for a business purpose.

     Regardless of any provision contained herein or in any of the Loan
Documents, the Lender shall never be entitled to receive, collect or apply as
interest on this Note, any amount in excess of the Maximum Rate, and, in the
event Lender ever receives, collects or applies as interest any such excess,
such amount which would be excessive interest shall be deemed a partial
prepayment of the principal and treated hereunder as such; and, if the total
outstanding principal is paid in full, any remaining excess shall forthwith be
paid to the Borrower. In determining whether or not the interest paid or payable
under any specific contingency, exceeds the Maximum Rate, Borrower and holder
hereof shall, to the maximum extent permitted under applicable law: (i)
characterize any non-principal payment as an expense, fee or premium rather than
as interest, (ii) exclude voluntary prepayments and the effects thereof, and
(iii) amortize, prorate, allocate and spread, in equal parts, the total amount
of interest throughout the entire contemplated term hereof. If the indebtedness
evidenced hereby is paid and performed in full prior to the end of the
contemplated term hereof, and if the interest received for the actual period of
existence hereof exceeds the Maximum Rate, Lender shall refund to Borrower the
amount of such excess, and, in such event, Lender shall not be subject to any
penalties provided by any laws for contracting for, charging, taking, reserving
or receiving interest in excess of the Maximum Rate.

     The Borrower may prepay the indebtedness evidenced hereby in whole or in
part at any time without penalty. The aggregate unpaid principal of all advances
under this Note shall be the principal amount owing and unpaid on this Note, and
all amounts outstanding on this Note shall be determined solely from the records
of the Lender. Borrower acknowledges that the sum

                                       2
<PAGE>

of $2,000,000 was advanced to the Borrower by Lender on the 29th day of May,
2001, which sum constitutes an advance of principal under the terms of this Note
and which sums shall bear interest in accordance with this Note accrued from the
date of such advanced, notwithstanding the date of this Note.

     The makers, endorsers, sureties, guarantors and all persons who may become
liable for all or any part of this obligation severally waive presentment for
payment, protest and notice of nonpayment. Said parties consent to any extension
of time (whether one or more) of payment hereof, any renewal (whether one or
more) hereof, release of all or any part of the security for the payment hereof,
release of any party liable for the payment of this obligation, acceptance of
additional collateral or security or guarantor for the payment of this
obligation, or any amendment or modification thereto. Any such extension,
renewal, release, acceptance, amendment or modification may be made without note
to any such party and without discharging said party's liability hereunder.

     The Lender and Borrower hereof recognize that because their domiciles may
differ, they might agree to the laws of various states to apply to the
interpretation and execution of this Note, and for simplicity and certainty, the
parties hereto agree that this Note shall be deemed to have been made, executed
and delivered in the State of Oklahoma, and the rights and liabilities of the
parties hereto shall be determined in accordance with the laws of the State of
Oklahoma except with respect to procedural laws of the situs state governing the
foreclosure of the Mortgage.

     The acceptance of this Note by Lender shall not constitute a commitment by
Lender to make advances hereunder. Advances will be made at Lender's sole
discretion.

     IN WITNESS WHEREOF, the undersigned Borrower has executed this Promissory
Note this 28th day of June, 2001, effective as of May 29, 2001.
