                               THE EXCHANGE OFFER
 
    We completed on December 23, 1998 the private offering of $200.0 million of
12 1/4% Senior Notes due 2008. We entered into a registration agreement with the
initial purchasers in the private offering in which we agreed, among other
things, to deliver to you this Prospectus and to complete the Exchange Offer
within 180 days of the issuance of the 12 1/4% Senior Notes due 2008. You are
entitled to exchange in the Exchange Offer your outstanding notes for registered
notes with substantially identical terms. If the Exchange Offer is not completed
within 180 days of the issuance of the 12 1/4% Senior Notes due 2008, then the
interest rates on the notes will be increased to 12 3/4% per year. You should
read the discussion under the heading "Summary Description of the New Notes" and
"Description of the New Notes" for further information regarding the registered
notes.
 
    We believe that the notes issued in the Exchange Offer may be resold by you
without compliance with the registration and prospectus delivery provisions of
the Securities Act, subject to certain conditions. You should read the
discussion under the headings "Summary of the Terms of Exchange Offer" and "The
Exchange Offer" for further information regarding the Exchange Offer and resale
of the notes.
 
                                  THE COMPANY
 
    We, through our wholly owned subsidiary, Sygnet, own and operate rural and
suburban cellular telephone systems serving a single large cluster of properties
with approximately 2.4 million Pops and 166,886 subscribers in northeastern
Ohio, western Pennsylvania and western New York. The cluster includes
Youngstown, Ohio, Erie, Pennsylvania, and suburban and rural areas between the
Cleveland, Akron-Canton, Pittsburgh, Buffalo and Rochester metropolitan areas.
We are a wholly owned subsidiary of Dobson.
 
    Sygnet has grown rapidly through selective acquisitions and internal growth.
Between 1993 and 1997, Sygnet's revenues increased at a compounded annual growth
rate of 56.0% and its Adjusted EBITDA increased at a compounded annual growth
rate of 71.1%. Excluding properties acquired during that period, Sygnet's
revenues increased at a compounded annual growth rate of 23.9% and its Adjusted
EBITDA increased at a compounded annual growth rate of 34.2%, over the same
period. In addition, from December 31, 1993 to September 30, 1998, Sygnet's
penetration rate increased from 2.5% to 7.0%. For the nine months ended
September 30, 1998, Sygnet had revenue of $76.9 million, operating income of
$15.1 million and Adjusted EBITDA of $36.4 million.
 
    On December 23, 1998, Dobson/Sygnet Operating Company, our subsidiary, was
merged into Sygnet. Sygnet has established and maintained a strong and visible
local presence. Since the merger, Sygnet's existing local management continues
to have day-to-day operating authority, with the flexibility to respond to
individual market requirements and to foster a strong sense of customer service
and community spirit. We expect to benefit from synergies resulting from
Dobson's centralization of certain functions such as control of pricing,
customer service and marketing, systems design, engineering, purchasing,
financial and administrative functions and from the consolidation of billing
functions. For example, we expect to consolidate Sygnet's three regional call
centers and one of Dobson's existing call centers. In addition, we
 
                                       1
<PAGE>
expect the Sygnet Acquisition to strengthen and expand Dobson's and Sygnet's
existing roaming partner relationships with AT&T Wireless because certain Sygnet
properties are adjacent to AT&T Wireless properties.
 
    Sygnet's markets are primarily rural and suburban and include a high
concentration of expressway corridors that tend to have a significant amount of
roaming activity. Roaming revenue represented approximately 32% (28% excluding
roaming by Sygnet customers into other Sygnet markets) of Sygnet's total
revenues for both the year ended December 31, 1997 and the nine months ended
September 30, 1998. Sygnet has entered into roaming agreements with operators of
cellular systems in adjoining MSAs and other MSAs which allow customers to roam
at competitive prices which, in certain instances, are comparable to Sygnet's
home area rates. Sygnet's principal roaming partners are AT&T Wireless, AirTouch
and SBC Communications. Sygnet also has roaming agreements with PCS providers,
such as AT&T Wireless and Sprint, to allow the PCS providers' customers with
dual mode telephones to roam in certain Sygnet markets.
 
    Through selective acquisitions, Sygnet has created an integrated network of
rural and suburban cellular systems in a contiguous service area. The following
table sets forth certain data with respect to Sygnet's cellular systems:

SYGNET ACQUISITION AND FINANCING PLAN
 
    On December 23, 1998, Dobson/Sygnet Operating Company, our subsidiary, was
merged with and into Sygnet. After the merger, Sygnet became our wholly owned
subsidiary and an indirect wholly owned subsidiary of Dobson. We paid $337.5
million in cash for all of the outstanding capital stock of Sygnet.
 
    In order to finance the Sygnet Acquisition, we consummated the following
transactions:
 
    -  Dobson made an equity contribution of approximately $145.0 million to us
       (the "Equity Contribution");
 
    -  Dobson/Sygnet Operating Company obtained a $430.0 million bank credit
       facility with NationsBank, N.A. ("NationsBank"), as agent, consisting of
       a $50.0 million reducing revolving credit facility (the "Revolving Credit
       Facility") and $380.0 million of term loans (the "Term Loan Facilities")
       (together the "New Bank Facilities");
 
    -  we issued and sold $200.0 million aggregate principal amount of the Old
       Notes, of which approximately $67.7 million was used to purchase a
       portfolio of U.S. government securities (the "Pledged Securities") that
       are pledged as security for the first six scheduled interest payments on
       the Notes;
 
    -  we repaid a $25.0 million loan from a subsidiary of Dobson used to make
       the deposit for the Sygnet Acquisition;
 
    -  Sygnet repaid all indebtedness outstanding under Sygnet's existing bank
       facility (the "Old Bank Facility");
 
    -  Sygnet repurchased (the "Sygnet Note Repurchase") all of Sygnet's
       outstanding 11 1/2% Senior Notes due 2006 (the "Sygnet Notes") that were
       tendered into Sygnet's offer to purchase the Sygnet Notes, which expired
       December 21, 1998 (the "Sygnet Tender Offer"); and
 
    -  Sygnet sold substantially all of its owned cellular towers for $25.0
       million in cash to Dobson Tower Company, a wholly owned subsidiary of
       Dobson, which leased the cellular towers back to Sygnet (the "Tower Sale
       Leaseback").
 
Each of these transactions (together with the Sygnet Acquisition, the
"Transactions") closed concurrently.

                   SUMMARY OF THE TERMS OF THE EXCHANGE OFFER
 
    The Exchange Offer relates to the exchange of up to $200.0 million aggregate
principal amount of outstanding notes for an equal aggregate principal amount of
new notes. The new notes will be our obligations entitled to the benefits of the
indenture governing the outstanding notes. The form and terms of the new notes
are identical in all material respects to the form and terms of the outstanding
notes except that the new notes have been registered under the Securities Act of
1933, and therefore are not entitled to the benefits of the registration rights
granted under the registration rights agreement, executed as part of the
offering of the outstanding notes, dated December 23, 1998 among the Company and
the initial purchasers in the private offering, including NationsBanc Montgomery

Registration Rights
  Agreement...................  You are entitled to exchange your notes for registered notes
                                with substantially identical terms. The Exchange Offer is
                                intended to satisfy these rights. After the Exchange Offer
                                is complete, you will no longer be entitled to any exchange
                                or registration rights with respect to your notes.
 
The Exchange Offer............  We are offering to exchange $1,000 principal amount of
                                12 1/4% Senior Notes due 2008 which have been registered
                                under the Securities Act of 1933 for each $1,000 principal
                                amount of our outstanding 12 1/4% Senior Notes due 2008
                                which were issued in December 1998 in a private offering. In
                                order to be exchanged, an outstanding note must be properly
                                tendered and accepted. All outstanding notes that are
                                validly tendered and not validly withdrawn will be
                                exchanged.
 
                                As of this date there are $200.0 million principal amount of
                                notes outstanding.
 
                                We will issue registered notes on or promptly after the
                                expiration of the Exchange Offer.
 
Resale of the New Notes.......  Based on an interpretation by the staff of the Commission
                                set forth in no-action letters issued to third parties,
                                including "Exxon Capital Holdings Corporation" (available
                                May 13, 1988) and "Morgan Stanley & Co. Incorporated"
                                (available June 5, 1991), we believe that the notes issued
                                in the exchange offer may be offered for resale, resold and
                                otherwise transferred by you without compliance with the
                                registration and prospectus delivery provisions of the
                                Securities Act of 1933 provided that:
 
                                    - the notes issued in the Exchange Offer are being
                                    acquired in the ordinary course of business;
 
                                    - you are not participating, do not intend to
                                    participate, and have no arrangement or understanding
                                      with any person to participate, in the distribution of
                                      the notes issued to you in the Exchange Offer;
 
                                    - you are not a broker-dealer who purchased such
                                    outstanding notes directly from us for resale pursuant
                                      to Rule 144A or any other available exemption under
                                      the Securities Act of 1933; and

                                    - you are not our "affiliate".
 
                                If our belief is inaccurate and you transfer any note issued
                                to you in the Exchange Offer without delivering a prospectus
                                meeting the requirement of the Securities Act of 1933 or
                                without an exemption from registration of your notes from
                                such requirements, you may incur liability under the
                                Securities Act of 1933. We do not assume or indemnify you
                                against such liability.
 
                                Each broker-dealer that is issued notes in the Exchange
                                Offer for its own account in exchange for notes which were
                                acquired by such broker-dealer as a result of market-making
                                or other trading activities, must acknowledge that it will
                                deliver a prospectus meeting the requirements of the
                                Securities Act of 1933, in connection with any resale of the
                                notes issued in the Exchange Offer. The Letter of
                                Transmittal states that by so acknowledging and by
                                delivering a prospectus, such broker-dealer will not be
                                deemed to admit that it is an "underwriter" within the
                                meaning of the Securities Act of 1933. A broker-dealer may
                                use this Prospectus for an offer to resell, resale or other
                                retransfer of the notes issued to it in the Exchange Offer.
                                We have agreed that, for a period of 180 days after the date
                                of this Prospectus, we will make this Prospectus and any
                                amendment or supplement to this Prospectus available to any
                                such broker-dealer for use in connection with any such
                                resales. We believe that no registered holder of the
                                outstanding notes is an affiliate (as such term is defined
                                in Rule 405 of the Securities Act of 1933) of the Company.
 
                                The Exchange Offer is not being made to, nor will we accept
                                surrenders for exchange from, holders of outstanding notes
                                in any jurisdiction in which this Exchange Offer or the
                                acceptance thereof would not be in compliance with the
                                securities or blue sky laws of such jurisdiction.
 
Expiration Date...............  The Exchange Offer will expire at 5:00 p.m., New York City
                                time,           , 1999, unless we decide to extend the
                                expiration date.
 
Accrued Interest on the New
  Notes and the Outstanding
  Notes.......................  The new notes will bear interest from December 23, 1998.
                                Holders of outstanding notes whose notes are accepted for
                                exchange will be deemed to have waived the right to receive
                                any payment of interest on such outstanding notes accrued
                                from December 23, 1998 to the date of the issuance of the
                                new notes. Consequently, holders who exchange their
                                outstanding notes for new notes will receive the same
                                interest payment on June 15, 1999 (the first interest
                                payment date with respect to the outstanding notes and the
                                new notes to be issued in the Exchange Offer) that they
                                would have received had they not accepted the Exchange
                                Offer.
 
Termination of the Exchange
  Offer.......................  We may terminate the Exchange Offer if we determine that our
                                ability to proceed with the Exchange Offer could be
                                materially impaired due to any legal or governmental action,
                                new law, statute, rule or regulation or any interpretation
                                of the staff of the Commission of any existing law, statute,

                                although there can be no assurance that such conditions will
                                not occur. Holders of outstanding notes will have certain
                                rights against our Company under the registration rights
                                agreement executed as part of the offering of the
                                outstanding notes should we fail to consummate the Exchange

                                note for exchange pursuant to the Exchange Offer, you must

                      SUMMARY DESCRIPTION OF THE NEW NOTES
 
<TABLE>
<S>                             <C>
Notes Offered.................  $200,000,000 aggregate principal amount of 12 1/4% Senior
                                Notes due 2008.
 
Maturity Date.................  December 15, 2008.
 
Interest Payment Dates........  June 15 and December 15 of each year, commencing June 15,
                                1999.
 
Ranking.......................  The notes will be unsecured senior subordinated obligations
                                and will be subordinated to all our exiting and future
                                senior indebtedness. The notes will rank equally with all
                                our other existing and future senior subordinated
                                indebtedness, and will rank senior to all our subordinated
                                indebtedness. The notes effectively will rank junior to all
                                liabilities of our subsidiaries. Because the notes are
                                subordinated, in the event of bankruptcy, liquidation or
                                dissolution, holders of the notes will not receive any
                                payment until holders of senior indebtedness have been paid
                                in full. The terms "senior indebtedness" and "subordinated
                                indebtedness" are defined in the "Description of the
                                Notes--Ranking" and "Description of the Notes--Certain
                                Definitions" sections of this Prospectus.
 
                                As of September 30, 1998, after giving pro forma effect to
                                the offering of the outstanding notes and our use of the net
                                proceeds from the offering and borrowings related to certain
                                acquisitions and related costs, we would have had no
                                indebtedness other than the notes and our subsidiaries would
                                have had $605.7 million of liabilities, including $398.2
                                million of indebtedness, all of which would have been
                                effectively senior to the notes.
 
Optional Redemption...........  We may redeem the notes, in whole or in part, at any time on
                                or after December 15, 2003, at the redemption prices set
                                forth in this Prospectus.
 
Public Equity Offering
  Optional Redemption.........  Before December 15, 2001, we may redeem up to 35% of the
                                aggregate principal amount of the notes with the net
                                proceeds of a public equity offering at 112.25% of the
                                principal amount thereof, plus accrued interest, if at least
                                65% of the aggregate principal amount of the notes
                                originally issued remains outstanding after such redemption.
                                See "Description of the Notes--Optional Redemption."
 
Change of Control.............  Upon certain change of control events, each holder of notes
                                may require us to repurchase all or a portion of its notes
                                at a purchase price equal to 101% of the principal amount
                                thereof, plus accrued interest. See "Description of the
                                Notes--Certain Definitions" for the definition of a Change
                                of Control.
 
Certain Covenants.............  The indenture governing the notes will contain covenants
                                that, among other things, will limit our ability and the
                                ability of our restricted subsidiaries to:
 
                                    - incur additional indebtedness,

          SUMMARY HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL DATA
 
    The following table sets forth certain historical consolidated financial
data for Sygnet with respect to each of the three years in the period ended
December 31, 1997 and for the nine months ended September 30, 1997 and 1998. The
summary historical consolidated financial data as of and for each of the three
years in the period 1995 to 1997 have been derived from Sygnet's audited
consolidated financial statements. The summary historical consolidated financial
data as of and for the nine months ended September 30, 1997 and 1998 have been
derived from Sygnet's unaudited consolidated financial statements. In the
opinion of management, the unaudited financial statements have been prepared on
the same basis as Sygnet's audited consolidated financial statements and include
all adjustments, which consist only of normal recurring adjustments, necessary
for a fair presentation of the information set forth therein. Operating results
for the nine months ended September 30, 1998 are not necessarily indicative of
results that may be expected for the full year. The pro forma consolidated
statement of operations data give effect to the Transactions as if they occurred
on January 1, 1997 and the pro forma consolidated balance sheet data give effect
to the Transactions as if they occurred on September 30, 1998. The summary
unaudited pro forma consolidated financial data are based on currently available
information and certain assumptions that management believes are reasonable. The
pro forma consolidated financial information does not purport to represent what
the Company's results of operations would have been if the Transactions had been
completed on such dates, nor does it purport to indicate the future financial
position or results of future operations of the Company. The information as set
forth below should be read in conjunction with "Use of Proceeds," "Selected
Consolidated Financial and Other Data," "Pro Forma Consolidated Financial Data,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the consolidated financial statements and the related notes
thereto included elsewhere in this offering memorandum.

    from October 9, 1996, the date of acquisition.
 
(3) Adjusted EBITDA represents earnings before interest expense, income taxes,
    depreciation and amortization, other income, extraordinary items, and
    changes in accounting principles. In addition, the Indenture governing the
    Notes contains certain covenant requirements that are based on Adjusted
    EBITDA. See "Description of the Notes--Covenants." Adjusted EBITDA is not
    derived pursuant to generally accepted accounting principles and should not
    be construed as an alternative to net income, as a measure of performance,
    or to cash flows, as a measure of liquidity. Adjusted EBITDA, as measured by
    the Company, may differ significantly from similarly named measurements of
    other companies and, as a consequence, may not provide any degree of
    reliable comparability. The calculation of Adjusted EBITDA does not include
    the Company's commitments for capital expenditures or payments of debts and
    should not be deemed to represent funds available to the Company.
 
(4) "Earnings" is defined as earnings before extraordinary items and accounting
    changes, interest expense, amortization of deferred financing costs, taxes
    and the portion of rent expense under operating leases representative of
    interest. Fixed charges consist of interest expense, amortization of
    deferred financing costs and a portion of rent expense under operating
    leases representative of interest. For the years ended December 31, 1996 and
    1997 and for the nine months ended September 30, 1997 and 1998, Sygnet's
    earnings were insufficient to cover its combined fixed charges and preferred
    stock dividends by $4.6 million, $22.7 million, $16.2 million and $6.6
    million, respectively. On a pro forma basis, for the year ended December 31,
    1997 and the nine months ended September 30, 1998, the Company's earnings
    would have been insufficient to cover its combined fixed charges and
    preferred stock dividends by $100.4 million and $65.9 million, respectively.
 
(5) Determined by dividing Sygnet's total ending cellular subscribers for the
    period by the estimated total Pops covered by applicable FCC cellular
    licenses or authorizations held by Sygnet.
 
(6) Churn means the number of cellular subscriber cancellations per period as a
    percentage of the weighted average total cellular subscribers during such
    period. Churn is stated as the average monthly churn rate for the period.
 
(7) Excludes roaming and equipment revenue.
 
(8) Determined by dividing cellular marketing and selling costs by the gross
    cellular subscribers added during such period. Cellular marketing and
    selling costs represent selling expenses and losses incurred on equipment
    sales and equipment rentals.

                                  RISK FACTORS
 
    IN ADDITION TO THE INFORMATION CONTAINED IN THIS PROSPECTUS, YOU SHOULD
CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS IN EVALUATING THE COMPANY AND ITS
BUSINESS.
 
LEVERAGE
 
    We are highly leveraged. At September 30, 1998, assuming that the
Transactions had been completed at the time, we would have had approximately
$598.2 million of consolidated indebtedness (including $398.2 million under the
New Bank Facilities) and $145.0 million of consolidated stockholder's equity. In
addition, under the same assumptions, our subsidiaries would have been able to
borrow $31.8 million of additional debt under the New Bank Facilities. The
indenture governing the notes also allows us and our subsidiaries to incur
substantial additional debt in the future. For the year ended December 31, 1997
and the nine months ended September 30, 1998, assuming the Transactions had been
completed on January 1, 1997, our Adjusted EBITDA would have been insufficient
to cover its interest expense by $23.4 million and $9.7 million, respectively,
and our Adjusted EBITDA minus interest expense and capital expenditures
(excluding costs of acquisitions) would have been $(49.0) million and $(21.2)
million, respectively. For the year ended December 31, 1997, under the same
assumptions, our earnings would have been insufficient to cover our combined
fixed charges and preferred stock dividends by $100.4 million. For the nine
months ended September 30, 1998, under the same assumptions, our earnings would
have been insufficient to cover our combined fixed charges and preferred stock
dividends by $65.9 million. Our level of indebtedness could have important
consequences, including:
 
    - the debt service requirements could make it more difficult for us to make
      required payments under the notes;
 
    - our ability to borrow additional money for working capital, capital
      expenditures, debt service requirements or other purposes will be limited;
 
    - a substantial portion of our future cash flow from operations will be
      required to pay principal and interest on its indebtedness and will not be
      available for our business;
 
    - our flexibility in planning for, or reacting to changes in, our business
      and our ability to take advantage of future business opportunities may be
      restricted;
 
    - we may be more highly leveraged than certain of our competitors, which may
      place us at a competitive disadvantage; and
 
    - our high degree of leverage could make us more vulnerable in the event of
      a downturn in our business.
 
ABILITY TO MEET DEBT SERVICE REQUIREMENTS
 
    In order for us to be able to meet our debt service requirements, including
our obligations under the notes, we must successfully implement our strategy.
Our strategy will be to focus on integrating our operations with Dobson's,
increasing our market penetration and further developing our cellular systems.
We cannot assure you that we will successfully implement our strategy or that we
will be able to generate enough cash flow from operating activities to meet our
debt service obligations as well as our other cash requirements, including for
working capital and capital expenditures. Furthermore, if Sygnet and its
subsidiary are unable to satisfy any of the covenants under the New Bank
Facilities, including financial covenants, they will be unable to borrow under
the New Bank Facilities during that time. Failure to obtain such financing could
result in the delay or abandonment of some or all of our plans, which could
limit our ability and that of our subsidiaries to meet debt service obligations
(including obligations with respect to the notes) and could have a material
adverse effect on our business. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources."
The ability of our subsidiaries to borrow under the New Bank Facilities will be
limited by the requirement that, on a quarterly basis beginning December 31,
2000, the amount available under the New Bank Facilities will
 
                                       13
<PAGE>
reduce until they terminate. The reduction in availability may require us to
make significant principal payments thereunder. See "Description of Certain
Indebtedness."
 
REFINANCING RISK
 
    We will need to refinance the New Bank Facilities and the notes at their
maturities. Our ability to do so will depend on, among other things, our
financial condition at the time, the restrictions in the instruments governing
their indebtedness and other factors, including market conditions, beyond our
control. If any of this indebtedness cannot be refinanced, it may cause a
default under the notes and we may be unable to meet our obligations under the
notes. In addition, in the event the implementation of our strategy to maintain
and expand our systems is delayed or we do not generate sufficient cash flow to
meet our debt service requirements, we may need to seek additional financing. We
cannot assure you that we could obtain any such refinancing or financing or
that, if obtained, it would be on acceptable terms. In the absence of such
refinancing or financing, we could be forced to sell assets at unfavorable
prices in order to make up for any shortfall. At September 30, 1998, after
giving effect to the Transactions, approximately 86.7% of our assets would have
consisted of intangible assets, principally licenses granted by the FCC. The
value of our intangible assets will depend upon a variety of factors, including
the success of our business and the wireless telecommunications industry in
general. In addition, transfers of interests in such licenses require FCC
approval. As a result, we cannot assure you that the assets could be sold
quickly enough, or for sufficient amounts, to enable us to meet our obligations,
including our obligations with respect to the Notes.
 
HOLDING COMPANY STRUCTURE
 
    We are a holding company with no direct operations and no significant assets
other than the stock of Sygnet and its operating subsidiary, Sygnet
Communications, Inc. ("Sygnet Communications"). We will be dependent on the cash
flows of Sygnet and its subsidiary to meet our obligations, including our
obligations to pay interest and principal on the notes. Sygnet and Sygnet
Communications' ability to distribute funds to us will be restricted by the
terms of their existing and future indebtedness, including the New Bank
Facilities. See "Description of Certain Indebtedness--New Bank Facilities."
 
    Sygnet and Sygnet Communications are separate legal entities that have no
obligation to make any funds available for the notes. Because Sygnet and Sygnet
Communications have not guaranteed the notes, any right we may have (and
therefore the holders of the notes) to receive assets of Sygnet or Sygnet
Communications upon their liquidation or reorganization will be effectively
junior to the claims of the creditors of such companies (including trade
creditors and holders of indebtedness), except to the extent we are a creditor
of Sygnet or Sygnet Communications. Sygnet has pledged the stock of Sygnet
Communications to secure borrowings under the New Bank Facilities. In addition,
Sygnet and its subsidiary have granted liens on substantially all of their
assets as security for the obligations under the New Bank Facilities. At
September 30, 1998, after giving effect to the Transactions, Sygnet and its
subsidiary would have had $605.7 million of liabilities, including $398.2
million of indebtedness, all of which would have been secured and effectively
senior to the Notes. See "Pro Forma Consolidated Financial Data" and
"Description of Certain Indebtedness."
 
ABILITY TO INCUR ADDITIONAL SECURED INDEBTEDNESS
 
    At September 30, 1998, after giving effect to the Transactions, we would
have had no outstanding indebtedness, other than the notes, and our subsidiaries
would have had $605.7 million of liabilities, including $398.2 million of
secured indebtedness, all of which would have been effectively senior to the
notes. The indenture governing the notes permits us and our subsidiaries to
incur additional indebtedness and to secure such indebtedness. In the event
Sygnet or its subsidiary borrows additional funds under the New Bank Facilities
or we or our subsidiaries obtain additional funds through the incurrence of
other secured indebtedness and we or our subsidiaries default with respect to
any such indebtedness, the holders of such indebtedness would be entitled to
payment out of the proceeds of their collateral prior to the holders of general
unsecured indebtedness, including the notes, despite the existence of an event
of default
 
                                       14
<PAGE>
with respect to the notes. Assets remaining after satisfaction of the claims of
creditors of Sygnet and its subsidiaries and the holders of our secured
indebtedness of the Company may not be sufficient to pay amounts due on any or
all of the notes then outstanding. See "Description of the Notes."
 
COVENANT RESTRICTIONS
 
    The indenture governing the notes and the credit agreement relating to the
New Bank Facilities (the "Credit Agreement") restrict or prohibit our ability
and that of our subsidiaries to incur additional indebtedness, pay dividends,
repay subordinated indebtedness prior to their maturities, sell assets, make
investments, engage in transactions with stockholders and affiliates, issue
capital stock, create liens or engage in mergers or acquisitions. In particular,
the New Bank Facilities limit the ability of Sygnet and Sygnet Communications to
pay dividends necessary for us to make payments on the notes. In addition, the
New Bank Facilities require Sygnet and us to maintain certain financial ratios.
See "Description of Certain Indebtedness--New Bank Facilities." These
restrictions may limit our ability and that of our subsidiaries to obtain future
financings, fund capital expenditures, or engage in other business activities
that may be in our interest. Our future indebtedness and that of our
subsidiaries may also contain significant restrictions.
 
    Our failure or that of our subsidiaries to comply with the restrictions in
their financing agreements could lead to a default under the terms of such
indebtedness and the notes even though we may be able to meet our debt service
obligations. In the event of a default, the holders of such indebtedness could
elect to declare all such indebtedness to be due and payable together with
accrued interest. We cannot assure you that we and our subsidiaries would be
able to make such payments or borrow enough funds from other sources to make any
such payments. Even if we could obtain additional financing, we cannot assure
you that it would be on terms that are acceptable to us. In addition, Sygnet's
obligations under the New Bank Facilities are secured by substantially all
assets of Sygnet and its subsidiaries. The pledge of the assets of Sygnet and
its subsidiaries to existing lenders could impair our ability and that of our
subsidiaries to obtain favorable financing. See "Description of Certain
Indebtedness."
 
REPURCHASE OF NOTES UPON A CHANGE OF CONTROL
 
    We must offer to purchase the notes upon the occurrence of a Change of
Control at a purchase price equal to 101% of their principal amount, plus
accrued interest. See "Description of the Notes-- Repurchase of Notes upon a
Change of Control."
 
    The New Bank Facilities prohibit us from prepaying the notes, including
required prepayments following a Change of Control. Prior to commencing an offer
to purchase, we would be required to (1) repay in full all of our indebtedness
and that of our subsidiaries that would prohibit the repurchase of the notes,
including indebtedness under the New Bank Facilities, or (2) obtain any consents
required to permit the repurchase. If we were unable to repay all of such
indebtedness or were unable to obtain the necessary consents, then we would be
unable to offer to purchase the notes, resulting in an event of default under
the indenture governing the notes. We cannot assure you that we will have enough
funds available at the time of any Change of Control offer to make any debt
payment (including repurchases of notes) as described above.
 
    The events that constitute a Change of Control under the indenture may also
be events of default under the New Bank Facilities or our other indebtedness and
that of our subsidiaries. Such events may permit the lenders under such debt to
declare the debt due and payable and, if the debt is not paid, to require us or
our subsidiaries to sell assets that secure such debt in order to repay the
lenders. In this case, our ability to raise cash to repurchase the notes would
be limited and would reduce the practical benefit of the offer to purchase
provisions to the holders of the notes. See "Description of Certain
Indebtedness."
 
RISKS ASSOCIATED WITH THE SYGNET ACQUISITION; CONFLICTS OF INTEREST
 
    Dobson intends to integrate the operations of Sygnet with its existing
cellular operations by centralizing pricing, customer service and marketing,
systems design, engineering, purchasing and financial and administrative
functions and from the consolidation of billing functions. However, we may face
some
 
                                       15
<PAGE>
difficulties as a result of (1) the loss of key Sygnet personnel, (2) the
integration of our corporate, accounting, financial reporting and management
information systems with Dobson's systems and (3) the strain on Dobson's
existing personnel who will largely manage both businesses. In addition,
telecommunications providers generally experience higher customer and employee
turnover rates during and after an acquisition. We cannot assure you that Dobson
will be able to successfully integrate Sygnet's operations or manage Sygnet's
business. Failure to integrate operations effectively and on a timely basis
could have a material adverse effect on our financial condition and results of
operations.
 
    All of our outstanding capital stock is owned by Dobson. In the future we
may engage in transactions with Dobson and its affiliates. Everett R. Dobson,
the Chairman and Chief Executive Officer of Dobson, serves as our Chairman and
Chief Executive Officer. In addition, G. Edward Evans, President and Chief
Operating Officer of Dobson's cellular operations, serves as our President and
Chief Operating Officer; Bruce R. Knooihuizen, the Vice President and Chief
Financial Officer of Dobson, serves as our Vice President and Chief Financial
Officer; and Stephen T. Dobson, the Secretary of Dobson, serves as our Treasurer
and Secretary. As a result, we are controlled by Dobson and Dobson is in a
position that may result in conflicts of interest with respect to transactions
involving Dobson and us, including negotiating the terms for providing services
to each other or enforcing any such arrangements. In addition, certain decisions
concerning our operations or financial structure may present conflicts of
interest between Dobson and the holders of the Notes.
 
    Certain of Dobson's markets are close to Sygnet's markets in Pennsylvania
and New York. Although our directors who are also directors or officers of
Dobson have certain fiduciary obligations to us, such directors and Dobson are
in positions that may create potential conflicts of interest with respect to
certain business opportunities available to and certain transactions involving
us. Neither Everett R. Dobson, Mr. Evans, Mr. Knooihuizen, nor Stephen T. Dobson
is obligated to present to us any particular investment opportunity which comes
to their attention, even if such opportunity is of a character which might be
suitable for investment by us.
 
COMPETITION
 
    The telecommunications industry is highly competitive. Many of our
competitors and potential competitors have substantially greater financial,
personnel, technical, marketing and other resources than do we, as well as other
competitive advantages. Currently the FCC authorizes only two cellular licensees
to operate in each license area and we compete in each of our markets with one
other cellular licensee. Competition for subscribers between cellular licensees
in a given license area is based principally upon price, the services and
enhancements offered, the technical quality of the cellular system, customer
service, system coverage and capacity. We also compete, although to a lesser
extent, with resellers, paging companies and landline telephone service
providers.
 
    As a result of recent regulatory and legislative initiatives, our cellular
operations may face increased competition from entities which use other
communications technologies or other radio frequency spectrum such as broadband
PCS licensees and enhanced specialized mobile radio ("ESMR") licensees. The FCC
has authorized as many as six broadband PCS licensees to provide services in
each of our markets, although not all of these licensees have begun servicing
those markets. Our operations may also face competition from other technologies
developed in the future including, but not limited to, satellite systems and
services provided over spectrum allocated to the Wireless Communications
Services ("WCS") and General Wireless Communications Services ("GWCS"). While
mobile services are not currently feasible on WCS spectrum, and GWCS spectrum
has not been licensed, mobile operations are not prohibited on such spectrum and
may emerge at some future date. We believe the likelihood of near-term
competition from such services is reduced because the areas in which we operate
are less densely populated. However, one or more of the technologies we
currently use in our business may become inferior or obsolete at some time in
the future. See "Business--Competition."
 
    We may not be able to continue to compete successfully and new technologies
and products that are more commercially accepted than ours may be developed.
Some competitors may market other services
 
                                       16
<PAGE>
such as long distance, cable television access or landline local exchange
services with their wireless offerings. There has been an industry trend of
declining average revenue per minute, as competition between service providers
has led to reductions in rates for airtime and subscriptions and other charges.
We expect that this trend will continue. See "Business--Competition" for more
detailed information on our competitive environment.
 
RAPID TECHNOLOGICAL CHANGES
 
    The telecommunications industry is subject to rapid and significant changes
in technology, including advancements protected by intellectual property laws.
Significant changes can be seen in the increasing pace of digital upgrades in
existing analog wireless systems, evolving industry standards, the availability
of new radio frequency spectrum allocations for wireless services, ongoing
improvements in the capacity and quality of digital technology, shorter
development cycles for new products and enhancements, developments in emerging
wireless transmission technologies and changes in end-user requirements and
preferences. International standards bodies and national regulators will
consider technology standards for new third-generation wireless technologies in
coming years, and we cannot assure you that our current technologies will be
compatible with such technologies. In addition, we may be required to select in
advance one technology over another. However, at the time we must make our
investment, we may not be able to accurately predict which technology will prove
to be the most economic, efficient or capable of attracting customer usage. We
also face uncertainty as to the extent of future customer demand as well as the
extent to which airtime and monthly access rates may continue to decline. The
effect of technological changes on our business cannot be predicted, and we
cannot assure you that technological developments will not have a material
adverse effect on us.
 
DEPENDENCE ON KEY PERSONNEL
 
    A small number of management and operating personnel at Dobson will also
manage and oversee our operations. The loss of certain of these individuals
could have a material adverse effect on us. We believe that our ability to
successfully manage our planned growth will depend in large part on our
continued ability to attract and retain highly skilled and qualified personnel.
See "--Risks Associated with the Sygnet Acquisition; Conflicts of Interest" and
"Management."
 
RELIANCE ON USE OF THIRD-PARTY SERVICE MARK
 
    We intend to continue to use the registered service mark CELLULAR
ONE-Registered Trademark- to promote the services Sygnet offers. Sygnet has
five-year contracts with Cellular One Group, the owner of the service mark, for
three of its four markets. These contracts begin to expire in 2001, and Sygnet
has an option to renew each of these contracts for two additional five-year
terms. See "Business--Service Marks." Under these agreements, Sygnet must meet
specified operating and service quality standards for its systems. If these
agreements are not renewed or if we fail to meet the applicable quality
standards, our ability both to attract new subscribers and retain existing
subscribers could be impaired. Recently, AT&T Wireless, which had been the
single largest user of the CELLULAR ONE-Registered Trademark- name, has
significantly reduced its use of the brand name as a primary service mark. If,
for this or some other reason beyond our control, the CELLULAR ONE-Registered
Trademark- mark was to suffer diminished marketing appeal, our ability both to
attract new subscribers and retain existing subscribers could be materially
impaired.
 
FRAUDULENT CONVEYANCE STATUTES
 
    Various laws enacted to protect creditors may apply to our incurrence of
indebtedness and other obligations in connection with the Transactions,
including the issuance of the notes. If a court were to find in a lawsuit by one
or more of our unpaid creditors or its or their representatives that we did not
receive fair consideration or reasonably equivalent value for incurring such
indebtedness or obligation and, at the time of such incurrence, we: (i) were
insolvent; (ii) were rendered insolvent by reason of such incurrence; (iii) were
engaged in a business or transaction for which our remaining assets constituted
unreasonably small capital; or (iv) intended to incur or believed we would incur
obligations beyond our ability to pay
 
                                       17
<PAGE>
such obligations as they mature, such court, subject to applicable statutes of
limitation, could decide to invalidate, in whole or in part, such indebtedness
and obligations as fraudulent conveyances or subordinate such indebtedness and
obligations to our existing or future creditors.
 
    The measure of insolvency for purposes of determining whether we made a
fraudulent conveyance will vary depending on the law of the jurisdiction which
is being applied. Generally, however, we would be considered insolvent at a
particular time if (i) the sum of our debts was then greater than all of our
property at a fair valuation or (ii) if the present fair saleable value of our
assets was then less than the amount that would be required to pay our probable
liabilities on our existing debts as they became due. On the basis of Sygnet's
historical financial information, Sygnet's recent operating history and other
factors, our management believes that, after giving effect to the Transactions,
we will not be rendered insolvent, will have sufficient capital for the business
in which we will be engaged and will be able to pay its debts as they mature;
however, our management has not obtained any independent opinion regarding such
issues. In addition, we cannot assure you as to what standard a court would
apply in making such determinations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
 
POTENTIAL FOR ADVERSE REGULATORY CHANGE AND THE NEED FOR REGULATORY APPROVALS
 
    The licensing, construction, operation, acquisition and sale of cellular
systems, as well as the number of cellular and other wireless licensees
permitted in each market, are regulated by the FCC. Changes in the regulation of
wireless activities and wireless carriers or the loss of any license or licensed
area could have a material adverse effect on our operations. In addition, all
cellular licenses in the United States must be renewed after the expiration of
their initial ten-year term. Our cellular licenses begin to expire in October
2000. We believe that each of these licenses will be renewed based upon FCC
rules establishing a presumption in favor of licensees that have complied with
their regulatory obligations during the initial license period. We cannot assure
you, however, that the FCC will renew our licenses. See "Business-- Regulation."
 
EQUIPMENT FAILURE AND NATURAL DISASTER
 
    A major equipment failure or a natural disaster affecting our central
switching office, our microwave links or certain of our cell sites could have a
material adverse effect on our operations.
 
RELIANCE ON ONE BILLING VENDOR
 
    We rely primarily on one vendor to produce all of our customer billings. If
this billing vendor for any reason were to encounter significant problems
affecting its ability to perform its billing functions for us, our ability to
generate billings to its customers would be materially impaired, until a new
arrangement could be established.
 
RADIO FREQUENCY EMISSION CONCERNS
 
    Media reports have suggested that certain radio frequency ("RF") emissions
from cellular telephones may be linked to cancer, and may interfere with
pacemakers and other medical devices. Concerns over RF emissions may discourage
the use of cellular telephones, which could have a material adverse effect on
our business. On August 1, 1996, the FCC released a report and order, which
became effective in August 1996 as to mobile and portable devices and October
1997 for cellular, that updates the guidelines and methods it uses for
evaluating RF emissions from radio equipment, including cellular telephones and
transmitting facilities. We do not believe these guidelines will have a material
impact on our operations. While the FCC's rules impose more restrictive
standards on RF emissions from lower power devices such as cellular telephones,
we believe, based on the certificates of manufacturers, that all cellular
telephones currently provided by Sygnet to its customers, as well as Sygnet's
transmitting facilities, comply with the FCC's standards. See
"Business--Regulation."
 
                                       18
<PAGE>
RISKS ASSOCIATED WITH THE YEAR 2000 ISSUE
 
    The "Year 2000 Issue" is the result of the inability of some computer
programs to distinguish the year 1900 from the year 2000. Most computer programs
and operating systems were written using two digits to define the applicable
year rather than four digits. This means that any equipment containing computer
programs with time-sensitive software may recognize a date using "00" as the
year 1900 rather than the year 2000. In some instances this could result in
system failures, disruption in operations and possible inaccuracies of data.
 
    Sygnet has substantially completed an inventory of all its systems and
equipment in each market to determine the impact of the Year 2000 Issue. Based
on this inventory, Sygnet has contacted its significant vendors to determine how
their products and services might be affected by the Year 2000 Issue. Generally,
Sygnet is relying upon representations made by the vendors as to their state of
readiness for the Year 2000 Issue. Based on internal evaluations and on
information provided by these vendors, certain systems have been upgraded and
tested for Year 2000 compliance. Sygnet estimates that it is 60% complete with
this phase of the project.
 
    Sygnet is placing special emphasis on areas that present a risk of
materially interrupting its revenue stream in the event of a Year 2000 problem.
Presently, it appears three main systems have the potential to materially
interrupt the revenue stream due to the Year 2000 Issue. They are the two
cellular switches, which could prevent calls from being made, and the billing
system, which could prevent Sygnet from billing and subsequently receiving
revenue from its customers. To address this risk, the Northern Telecom switch,
which serves Sygnet's Ohio and Pennsylvania markets, has recently undergone a
software upgrade to a Year 2000 compliant version. Sygnet has monitored testing
of this software in a Year 2000 situation with commonly known critical dates and
has encountered no problems. Accordingly, Sygnet has deemed this system to have
a minimal risk of failure regarding the Year 2000 Issue and will not develop
contingency plans for the Northern Telecom switch unless new information becomes
available that suggests a contingency plan is warranted. The Ericsson switch,
which serves Sygnet's New York market, is expected to have its software upgraded
to a Year 2000 compliant version in the first quarter of 1999. In connection
with the planned upgrade of the New York system, the Company plans to replace
the Ericsson switching equipment with Northern Telecom equipment that is
believed to be Year 2000 compliant. In addition, the upgrade of the billing
system software to a Year 2000 compliant version is expected to be completed in
the first quarter of 1999. The vendor that provides this system has indicated
that Year 2000 compliance testing will be completed by June of 1999. Sygnet has
deemed this system to have a moderate risk of not being able to handle the Year
2000 requirements and a contingency plan is being prepared that may include
selecting a new billing vendor in mid-1999.
 
    The cost of testing and upgrading these systems can not be determined at
this time. Our current estimate of the cost of becoming Year 2000 compliant is
$250,000 or less. This estimate may change significantly downward or upward as
the process continues or if problems arise with either a switch or billing
system. Additionally, this estimate may change substantially if other systems or
vendors are unable to become Year 2000 compliant causing a material interruption
of the revenue stream.
 
LACK OF PUBLIC MARKET FOR THE NOTES; RESTRICTIONS ON TRANSFERABILITY
 
    The notes are a new issue of securities for which there is currently no
active trading market. The notes may trade for less than their initial offering
price, depending upon prevailing interest rates, the market for similar
securities, our financial condition and prospects and other factors beyond our
control, including general economic conditions. We do not intend to apply for a
listing or quotation of the notes. Although the Initial Purchasers have informed
us that they intend to make a market in the notes, they are not obligated to do
so and any such market making activities may be discontinued at any time without
notice. Accordingly, we cannot assure you as to the development or liquidity of
any trading market for the Notes.
 
    Your notes have not been registered under the Securities Act or any state
securities laws and may not be offered or sold, except pursuant to an exemption
from, or in a transaction not subject to, the registration requirements of the
Securities Act and applicable state securities laws, or pursuant to an
 
                                       19
<PAGE>
effective registration statement. We have registered the New Notes under the
Securities Act and are obligated to use our best efforts to complete an exchange
offer for the Notes or register resales of the Notes under the Securities Act,
but we cannot assure you as to the development or liquidity of the trading
market of the Notes thereafter. See "Description of the Notes--Registration
Rights."
 
FORWARD-LOOKING STATEMENTS
 
    The description of our plans set forth herein, including our strategies,
planned capital expenditures, Year 2000 preparedness and anticipated cost
savings, are forward-looking statements. These plans involve a number of risks
and uncertainties. Important factors that could cause actual capital
expenditures, Year 2000 preparedness, acquisition activity, or our performance
to differ materially from our plans include, without limitation:
 
    - our ability to satisfy the financial covenants of its existing and future
      debt instruments and to raise additional capital;
 
    - our ability to integrate our operations with Dobson's existing operations
      and to successfully market our services and products to existing and new
      customers;
 
    - our ability to install equipment and expand and upgrade our systems in a
      timely manner and to manage our rapid growth successfully;
 
    - our ability to compete effectively against competitors with greater
      financial, technical, marketing and other resources and respond
      effectively to changes in end-user requirements and preferences;
 
    - the inability of third party vendors to provide products and services
      which are Year 2000 compliant;
 
    - the development of other technologies and products that may gain more
      commercial acceptance than ours; and
 
    - adverse regulatory changes.
 
We cannot assure you that anticipated future results will be achieved. Actual
events or results may differ materially as a result of risks to which we are or
may be subject. Readers are cautioned not to place undue reliance on these
forward-looking statements which speak only as of the date hereof. We do not
intend to update or revise these forward-looking statements to reflect events or
circumstances after the date hereof including, without limitation, changes in
our business strategy or planned capital expenditures, or to reflect the
occurrence of unanticipated events.

                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
    The Old Notes were sold by the Company on December 23, 1998 to NationsBanc
Montgomery Securities LLC, Lehman Brothers Inc., First Union Capital Markets, a
division of Wheat First Securities, Inc., and TD Securities (USA) Inc.
(together, the "Initial Purchasers") in reliance on Section 4(2) of the
Securities Act. The Initial Purchasers offered and sold the Old Notes only (i)
to "qualified institutional buyers" (as defined in Rule 144A) in compliance with
Rule 144A and (ii) outside the United States to persons other than U.S. Persons,
which term includes dealers or other professional fiduciaries in the United
States acting on a discretionary basis for foreign beneficial owners (other than
an estate or trust), in reliance upon Regulation S under the Securities Act.
 
    In connection with the sale of the Old Notes, the Company and the Initial
Purchasers entered into a Registration Rights Agreement dated as of December 23,
1998, which required the Company to file with the Commission a registration
statement under the Securities Act with respect to the new notes (the "New
Notes," together with the Old Notes, the "Notes") and use its best efforts to
cause such registration statement to become effective under the Securities Act
and, upon the effectiveness of that registration statement, to offer to the
holders of the Old Notes the opportunity to exchange their Old Notes for a like
principal amount of New Notes, which will be issued without a restrictive legend
and which may be reoffered and resold by the holder without restrictions or
limitations under the Securities Act. A copy of the Registration Rights
Agreement has been filed as an exhibit to the registration statement (the
"Registration Statement") of which this Prospectus is a part. The Exchange Offer
is being made pursuant to the Registration Rights Agreement to satisfy the
Company's obligations thereunder. The term "holder" with respect to the Exchange
Offer means any person in whose name Old Notes are registered on the Company's
books or any other person who has obtained a properly completed stock power from
the registered holder, or any person whose Old Notes are held of record by The
Depository Trust Company ("DTC") who desires to deliver such Old Notes by
book-entry transfer at DTC.
 
    The Company has not requested, and does not intend to request, an
interpretation by the staff of the Securities and Exchange Commission (the
"Commission") with respect to whether the New Notes issued pursuant to the
Exchange Offer in exchange for the Old Notes may be offered for sale, resold or
otherwise transferred by any holder without compliance with the registration and
prospectus delivery provisions of the Securities Act of 1933, as amended (the
"Securities Act"). Based on interpretations by the staff of the Commission set
forth in no-action letters issued to third parties, the Company believes the New
Notes issued pursuant to the Exchange Offer in exchange for Old Notes may be
offered for resale, resold and otherwise transferred by any holder thereof
(other than broker-dealers, as set forth below, and any such holder that is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act) without compliance with the registration and prospectus delivery provisions
of the Securities Act, provided that such New Notes are acquired in the ordinary
course of such holder's business and that such holder has no arrangement or
understanding with any person to participate in the distribution of such New
Notes. Any holder who tenders in the Exchange Offer with the intention to
participate, or for the purpose of participating in a distribution of the New
Notes or who is an affiliate of the Company may not rely upon such
interpretations by the staff of the Commission and, in the absence of an
exemption therefrom, must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any secondary resale
transaction. Failure to comply with such requirements in such instance may
result in such holder incurring liabilities under the Securities Act for which
the holder is not indemnified by the Company. Each broker-dealer (other than an
affiliate of the Company) that receives New Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus meeting
the requirements of the Securities Act in connection with any resale of such New
Notes. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. The Company has
 
                                       21
<PAGE>
agreed that, for a period of 180 days after the Exchange Date, it will make the
Prospectus available to any broker-dealer for use in connection with any such
resale. See "Plan of Distribution."
 
    The Exchange Offer is not being made to, nor will the Company accept
surrenders for exchange from, holders of Old Notes in any jurisdiction in which
this Exchange Offer or the acceptance thereof would not be in compliance with
the securities or blue sky laws of such jurisdiction.
 
    By tendering in the Exchange Offer, each holder of Old Notes will represent
to the Company that, among other things, (i) the New Notes acquired pursuant to
the Exchange Offer are being obtained in the ordinary course of business of the
person receiving such New Notes, whether or not such person is the holder, (ii)
neither the holder of Old Notes nor any such other person has an arrangement or
understanding with any person to participate in the distribution of such New
Notes, (iii) if the holder is not a broker-dealer, or is a broker-dealer but
will not receive New Notes for its own account in exchange for Old Notes,
neither the holder nor any such person is engaged in or intends to participate
in the distribution of such New Notes, and (iv) neither the holder nor any such
other person is an "affiliate" of the Company within the meaning of Rule 405
under the Securities Act or, if such holder is an "affiliate," that such holder
will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable.
 
    Following the completion of the Exchange Offer, none of the Old Notes will
be entitled to the contingent increase in interest rate applicable to the Old
Notes. Following the consummation of the Exchange Offer, holders of Old Notes
will not have any further registration rights, and the Old Notes will continue
to be subject to certain restrictions on transfer. See "--Consequences of
Failure to Exchange." Accordingly, the liquidity of the market for the Old Notes
could be adversely affected. See "Risk Factors-- Consequences of the Exchange
Offer on Non-Tendering holders of the Old Notes."
 
    Participation in the Exchange Offer is voluntary and holders should
carefully consider whether to accept. Holders of the Old Notes may wish to
consult their own financial advisors and tax advisors with respect to their
particular tax situation in making their own decisions on whether to participate
in the Exchange Offer.
 
TERMS OF THE EXCHANGE OFFER
 
    GENERAL  Upon the terms and subject to the conditions set forth in this
Prospectus and in the Letter of Transmittal, the Company will accept any and all
Old Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City
time, on the Expiration Date. The Company will issue $1,000 principal amount of
New Notes in exchange for each $1,000 principal amount of Old Notes accepted in
the Exchange Offer. Holders may tender some or all of their Old Notes pursuant
to the Exchange Offer. However, Old Notes may be tendered only in amounts that
are integral multiples of $1,000 principal amount.
 
    The form and terms of the New Notes will be identical in all material
respects to the form and terms of the Old Notes except that the New Notes will
be registered under the Securities Act and, therefore, certificates representing
New Notes will not bear legends restricting the transfer thereof. The New Notes
will evidence the same debt as the Old Notes, will be entitled to the benefits
of the Indenture and will be treated as a single class thereunder with any Old
Notes that remain outstanding. The Exchange Offer is not conditioned upon any
minimum number of Old Notes being tendered for exchange.
 
    As of December 31, 1998, $200,000,000 aggregate principal amount of the Old
Notes were outstanding. The Prospectus, together with the Letter of Transmittal,
is being sent to all registered holders.
 
    Holders of Old Notes do not have any appraisal or dissenters' rights under
the Oklahoma General Corporation Act or the indenture governing the Notes (the
"Indenture") in connection with the Exchange Offer. The Company intends to
conduct the Exchange Offer in accordance with the provisions of the Registration
Rights Agreement and the applicable requirements of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), and the rules and regulations of the
Commission thereunder. Old Notes
 
                                       22
<PAGE>
which are not tendered for exchange in the Exchange Offer will remain
outstanding and interest thereon will continue to accrue, but such Old Notes
will not be entitled to any rights or benefits under the Registration Rights
Agreement.
 
    The Company will be deemed to have accepted validly tendered Old Notes when,
as and if the Company has given oral or written notice thereof to the Exchange
Agent. The Exchange Agent will act as agent for the tendering holders for the
purposes of receiving the New Notes from the Company. If any tendered Old Notes
are not accepted for exchange because of an invalid tender, the occurrence of
certain other events set forth herein or otherwise, certificates for any such
unaccepted Old Notes will be returned, without expense, to the tendering holder
thereof as promptly as practicable after the Expiration Date.
 
    Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other than certain applicable taxes described below, in connection with the
Exchange Offer. See "--Fees and Expenses."
 
    EXPIRATION DATE; EXTENSIONS; AMENDMENTS.  The term "Expiration Date" shall
mean 5:00 p.m., New York City time, on           , 1999, unless the Company, in
its sole discretion, extends the Exchange Offer, in which case the term
"Expiration Date" shall mean the latest date and time to which the Exchange
Offer is extended. Although the Company has no current intention to extend the
Exchange Offer, the Company reserves the right to extend the Exchange Offer at
any time and from time to time by giving oral or written notice to the Exchange
Agent and by timely public announcement communicated, unless otherwise required
by applicable law or regulation, by making a release to the Dow Jones News
Service. During any extension of the Exchange Offer, all Old Notes previously
tendered pursuant to the Exchange Offer and not withdrawn will remain subject to
the Exchange Offer. The date of the exchange of the New Notes for Old Notes will
be as soon as practicable following the Expiration Date.
 
    The Company reserves the right, in its sole discretion, (i) to delay
accepting any Old Notes, to extend the Exchange Offer or to terminate the
Exchange Offer if any of the conditions set forth below under "--Conditions of
the Exchange Offer" shall not have been satisfied, by giving oral or written
notice of such delay, extension or termination to the Exchange Agent, or (ii) to
amend the terms of the Exchange Offer in any manner. Any such delay in
acceptance, extension, termination or amendment will be followed as promptly as
practicable by oral or written notice thereof to the registered holders. If the
Exchange Offer is amended in any manner determined by the Company to constitute
a material change, the Company will promptly disclose such amendment by means of
a prospectus supplement that will be distributed to the registered holders, and
the Company will extend the Exchange Offer for a period of time, depending upon
the significance of the amendment and the manner of disclosure to the registered
holders, if the Exchange Offer would otherwise expire during such period.
 
    In all cases, issuance of the New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of a properly completed and duly executed Letter of
Transmittal and all other required documents; provided, however, that the
Company reserves the absolute right to waive any conditions of the Exchange
Offer or defects or irregularities in the tender of Old Notes. If any tendered
Old Notes are not accepted for any reason set forth in the terms and conditions
of the Exchange Offer or if Old Notes are submitted for a greater principal
amount than the holder desires to exchange, such unaccepted or non-exchanged Old
Notes or substitute Old Notes evidencing the unaccepted portion, as appropriate,
will be returned without expense to the tendering holder, unless otherwise
provided in the Letter of Transmittal, as promptly as practicable after the
expiration or termination of the Exchange Offer.
 
    INTEREST ON THE NEW NOTES.  Holders of Old Notes that are accepted for
exchange will not receive accrued interest thereon at the time of exchange.
However, each New Note will bear interest from the
 
                                       23
<PAGE>
most recent date to which interest has been paid on the Old Notes or New Notes,
or if no interest has been paid on the Old Notes or the New Notes, from December
23, 1998.
 
    PROCEDURES FOR TENDERING OLD NOTES.  The tender to the Company of Old Notes
by a holder thereof pursuant to one of the procedures set forth below will
constitute an agreement between such holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal. A holder of the Old Notes may tender such Old Notes by (i) properly
completing and signing a Letter of Transmittal or a facsimile thereof (all
references in this Prospectus to a Letter of Transmittal shall be deemed to
include a facsimile thereof) and delivering the same, together with any
corresponding certificate or certificates representing the Old Notes being
tendered (if in certificated form) and any required signature guarantees, to the
Exchange Agent at its address set forth in the Letter of Transmittal on or prior
to the Expiration Date (or complying with the procedure for book-entry transfer
described below), or (ii) complying with the guaranteed delivery procedures
described below.
 
    If tendered Old Notes are registered in the name of the signer of the Letter
of Transmittal and the New Notes to be issued in exchange therefor are to be
issued (and any untendered Old Notes are to be reissued) in the name of the
registered holder (which term, for the purposes described herein, shall include
any participant in DTC (also referred to as a book-entry facility) whose name
appears on a security listing as the owner of Old Notes), the signature of such
signer need not be guaranteed. In any other case, the tendered Old Notes must be
endorsed or accompanied by written instruments of transfer in form satisfactory
to the Company and duly executed by the registered holder and the signature on
the endorsement or instrument of transfer must be guaranteed by an eligible
guarantor institution which is a member of one of the following recognized
signature guarantee programs (an "Eligible Institution"): (i) The Securities
Transfer Agents Medallion Program (STAMP), (ii) The New York Stock Exchange
Medallion Signature Program (MSF), or (iii) The Stock Exchange Medallion Program
(SEMP). If the New Notes or Old Notes not exchanged are to be delivered to an
address other than that of the registered holder appearing on the note register
for the Old Notes, the signature in the Letter of Transmittal must be guaranteed
by an Eligible Institution.
 
    THE METHOD OF DELIVERY OF OLD NOTES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
HOLDER. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT
TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO THE EFFECT THE ABOVE
TRANSACTIONS FOR SUCH HOLDERS.
 
    The Company understands that the Exchange Agent has confirmed with DTC that
any financial institution that is a participant in DTC's system may utilize
DTC's Automated Tender Offer Program ("ATOP") to tender Old Notes. The Company
further understands that the Exchange Agent will request, within two business
days after the date the Exchange Offer commences, that DTC establish an account
with respect to the Old Notes for the purpose of facilitating the Exchange
Offer, and any participant may make book-entry delivery of Old Notes by causing
DTC to transfer such Old Notes into the Exchange Agent's account in accordance
with DTC's ATOP procedures for transfer. However, the exchange of the Old Notes
so tendered will only be made after timely confirmation (a "Book-Entry
Confirmation") of such book-entry transfer and timely receipt by the Exchange
Agent of an Agent's Message (as defined in the next sentence), and any other
documents required by the Letter of Transmittal. The term "Agent's Message"
means a message, transmitted by DTC and received by the Exchange Agent and
forming part of Book-Entry Confirmation, which states that DTC has received an
express acknowledgment from a participant tendering Old Notes which are the
subject of such Book-Entry Confirmation and that such
 
                                       24
<PAGE>
participant has received and agrees to be bound by the terms of the Letter of
Transmittal and that the Company may enforce such agreement against such
participant.
 
    A tender will be deemed to have been received as of the date when (i) the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a confirmation of book-entry transfer of such
Old Notes into the Exchange Agent's account at DTC), is received by the Exchange
Agent, or (ii) a Notice of Guaranteed Delivery or letter, telegram or facsimile
transmission to similar effect (as provided below) from an Eligible Institution
is received by the Exchange Agent. Issuances of New Notes in exchange for Old
Notes tendered pursuant to a Notice of Guaranteed Delivery or letter, telegram
or facsimile transmission to similar effect (as provided below) by an Eligible
Institution will be made only against submission of a duly signed Letter of
Transmittal (and any other required documents) and deposit of the tendered Old
Notes.
 
    All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of Old Notes will be
determined by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all tenders not in proper
form or the acceptance for exchange of which may, in the opinion of the
Company's counsel, be unlawful. The Company also reserves the absolute right to
waive any of the conditions of the Exchange Offer or any defect or irregularity
in the tender of any Old Notes. None of the Company, the Exchange Agent or any
other person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification. Any Old Notes received by the Exchange Agent that are not validly
tendered and as to which the defects or irregularities have not been cured or
waived, or if Old Notes are submitted in principal amount greater than the
principal amount of Old Notes being tendered by such tendering holder, such
unaccepted or non-exchanged Old Notes will be returned by the Exchange Agent to
the tendering holder, unless otherwise provided in the Letter of Transmittal, as
soon as practicable following the Expiration Date.
 
    In addition, the Company reserves the right in its sole discretion (a) to
purchase or make offers for any Old Notes that remain outstanding subsequent to
the Expiration Date, and (b) to the extent permitted by applicable law, to
purchase Old Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers will differ from the terms
of the Exchange Offer.
 
    GUARANTEED DELIVERY PROCEDURES.  If the holder desires to accept the
Exchange Offer and time will not permit a Letter of Transmittal or Old Notes to
reach the Exchange Agent before the Expiration Date or the procedure for the
book-entry transfer cannot be completed on a timely basis, a tender may be
effected if the Exchange Agent has received at its office, on or prior to the
Expiration Date, a letter, telegram or facsimile transmission from an Eligible
Institution setting forth the name and address of the tendering holder, the
name(s) in which the Old Notes are registered and the certificate number(s) of
the Old Notes to be tendered, and stating that the tender is being made thereby
and guaranteeing that, within three New York Stock Exchange trading days after
the date of execution of such letter, telegram or facsimile transmission by the
Eligible Institution, such Old Notes, in proper form for transfer (or a
confirmation of book-entry transfer of such Old Notes into the Exchange Agent's
account at DTC), will be delivered by such Eligible Institution together with a
properly completed and duly executed Letter of Transmittal (and any other
required documents). Unless Old Notes being tendered by the above-described
method are deposited with the Exchange Agent within the time period set forth
above (accompanied or preceded by a properly competed Letter of Transmittal and
any other required documents), the Company may, at its option, reject the
tender. Copies of a Notice of Guaranteed Delivery which may be used by Eligible
Institutions for the purposes described in this paragraph are available from the
Exchange Agent.
 
    TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL.  The Letter of
Transmittal contains, among other things, the following terms and conditions,
which are part of the Exchange Offer.
 
                                       25
<PAGE>
    The party tendering Old Notes for exchange (the "Transferor") exchanges,
assigns and transfers the Old Notes to the Company and irrevocably constitutes
and appoints the Exchange Agent as the Transferor's agent and attorney-in-fact
to cause the Old Notes to be assigned, transferred and exchanged. The Transferor
represents and warrants that it has full power and authority to tender,
exchange, assign and transfer the Old Notes and to acquire New Notes issuable
upon the exchange of such tendered Old Notes, and that, when the same are
accepted for exchange, the Company will acquire good and unencumbered title to
the tendered Old Notes, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claim. The Transferor also warrants
that it will, upon request, execute and deliver any additional documents deemed
by the Company to be necessary or desirable to complete the exchange, assignment
and transfer of tendered Old Notes or to transfer ownership of such Old Notes on
the account books maintained by DTC. All authority conferred by the Transferor
will survive the death, bankruptcy or incapacity of the Transferor and every
obligation of the Transferor shall be binding upon the heirs, personal
representatives, executors, administrators, successors, assigns, trustees in
bankruptcy and other legal representatives of such Transferor.
 
    By executing a Letter of Transmittal, each holder will make to the Company
the representations set forth above under the heading "--Purpose and Effect of
the Exchange Offer."
 
    WITHDRAWAL OF TENDERS OF OLD NOTES.  Except as otherwise provided herein,
tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York
City time, on the Expiration Date.
 
    To withdraw a tender of Old Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to 5:00 p.m., New York City time, on
the Expiration Date. Any such notice of withdrawal must (i) specify the names of
the person having deposited the Old Notes to be withdrawn (the "Depositor"),
(ii) identify the Old Notes to be withdrawn (including the certificate number or
numbers and principal amount of such Old Notes), (iii) contain a statement that
such holder is withdrawing its election to have such Old Notes exchanged, (iv)
be signed by the holder in the same manner as the original signature on the
Letter of Transmittal by which such Old Notes were tendered (including any
required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the Old Notes register the
transfer of such Old Notes in the name of the person withdrawing the tender, and
(v) specify the name in which any such Old Notes are to be registered, if
different from that of the Depositor. If Old notes have been tendered pursuant
to the procedure for book-entry transfer, any notice of withdrawal must specify
the name and number of the account at the book-entry transfer facility. All
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by the Company, whose determination shall be
final and binding on all parties. Any Old Notes so withdrawn will be deemed not
to have been validly tendered for purposes of the Exchange Offer and no New
Notes will be issued with respect thereto unless the Old Notes so withdrawn are
validly retendered. Any Old Notes which have been tendered but which are not
accepted for exchange will be returned to the holder thereof without cost to
such holder as soon as practicable after withdrawal, rejection of tender or
termination of the Exchange Offer. Properly withdrawn Old Notes may be
retendered by following one of the procedures described above under
"--Procedures for Tendering Old Notes" at any time prior to the Expiration Date.
 
CONDITIONS OF THE EXCHANGE OFFER
 
    Notwithstanding any other term of the Exchange Offer, or any extension of
the Exchange Offer, the Company shall not be required to accept for exchange, or
exchange New Notes for, any Old Notes, and may terminate the Exchange Offer as
provided herein on or before the Expiration Date, if:
 
        (a) any statute, rule or regulation shall have been enacted, or any
    action shall have been taken by any court or governmental authority which,
    in the reasonable judgment of the Company, would prohibit, restrict or
    otherwise render illegal consummation of the Exchange Offer; or
 
                                       26
<PAGE>
        (b) any change, or any development involving a prospective change, in
    the business or financial affairs of the Company or any of its subsidiaries
    has occurred which, in the reasonable judgment of the Company, might
    materially impair the ability of the Company to proceed with the Exchange
    Offer or materially impair the contemplated benefits of the Exchange Offer
    to the Company; or
 
    (c) there shall occur a change in the current interpretations by the staff
of the Commission which, in the Company's reasonable judgment, might materially
impair the Company's ability to proceed with the Exchange Offer
 
and the Company does not wave such event or change.
 
    If the Company determines in its sole discretion that any of the above
conditions have not been satisfied on or prior to the Expiration Date, the
Company may (i) refuse to accept any Old Notes and return all tendered Old Notes
to the tendering holders, (ii) extend the Exchange Offer and retain all Old
Notes tendered prior to the Expiration Date, subject, however, to the right of
holders to withdraw such Old Notes (see "--Terms of the Exchange
Offer--Withdrawal of Tenders of Old Notes"), or (iii) waive such unsatisfied
conditions with respect to the Exchange Offer and accept all validly tendered
Old Notes which have not been withdrawn. If such waiver constitutes a material
change to the Exchange Offer, the Company will promptly disclose such waiver by
means of a prospectus supplement that will be distributed to the registered
holders, and the Company will extend the Exchange Offer for a period of time,
depending upon the significance of the waiver and the manner of disclosure to
the registered holders, if the Exchange Offer would otherwise expire during such
period.

FEES AND EXPENSES
 
    The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telecopy, telephone or in person by officers and regular
employees of the Company and its affiliates. No additional compensation will be
paid to any such officers and employees who engage in soliciting tenders.
 
                                       27
<PAGE>
    The Companyy has not retained any dealer-manager or other soliciting agent
in connection with the Exchange Offer and will not make any payments to brokers,
dealers or others soliciting acceptance of the Exchange Offer. The Company,
however, will pay the Exchange Agent reasonable and customary fees for its
services and will reimburse it for its reasonable out-of-pocket expenses in
connection therewith. The Company may also pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding copies of this Prospectus, the Letter of
Transmittal and related documents to the beneficial owners of the Old Notes and
in handling or forwarding tenders for exchange.
 
    The expenses to be incurred in connection with the Exchange Offer will be
paid by the Company. Such expenses include fees and expenses of the Exchange
Agent and transfer agent and registrar, accounting and legal fees and printing
costs, among others.
 
    The Company will pay all transfer taxes, if any, applicable to the exchange
of the Old Notes pursuant to the Exchange Offer. If, however, New Notes, or Old
Notes for principal amounts not tendered or accepted for exchange, are to be
delivered to, or are to be issued in the name of, any person other than the
registered holder of the Old Notes tendered or if a transfer tax is imposed for
any reason other than the exchange of the Old Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
    The Old Notes that are not exchanged for New Notes pursuant to the Exchange
Offer will remain restricted securities within the meaning of Rule 144 of the
Securities Act. Accordingly, such Old Notes may be resold only (i) to the
Company or any subsidiary thereof, (ii) to a qualified institutional buyer in
compliance with Rule 144A, (iii) to an institutional accredited investor that,
prior to such transfer, furnishes to the Trustee a signed letter containing
certain representations and agreements relating to the restrictions on transfer
of the Old Notes (the form of which letter can be obtained from the Trustee)
and, if such transfer is in respect of an aggregate principal amount of Old
Notes at the time of transfer of less than $100,000, an opinion of counsel
acceptable to the Company that such transfer is in compliance with the
Securities Act, (iv) outside the United States in compliance with Role 904 under
the Securities Act, (v) pursuant to the exemption from registration provided by
Section 4(2) of under the Securities Act, and Rule 144 adopted thereunder (if
available), or (vi) pursuant to an effective registration statement under the
Securities Act. The liquidity of the Old Notes could be adversely affected by
the Exchange Offer. Following the consummation of the Exchange Offer, holders of
the Senior Preferred Stock will have no further registration rights under the
Registration Rights Agreement and will not be entitled to the contingent
increase in the dividend rate applicable to the Old Notes.

                 SELECTED CONSOLIDATED FINANCIAL AND OTHER DATA
 
    The following table sets forth certain historical consolidated financial
data for Sygnet with respect to each of the five years in the period ended
December 31, 1997 and for the nine months ended September 30, 1997 and 1998. The
selected historical consolidated financial data as of each of the five years
ended December 31, 1997 were derived from Sygnet's audited consolidated
financial statements and for the nine months ended September 30, 1997 and 1998
have been derived from Sygnet's unaudited consolidated financial statements. In
the opinion of management, the unaudited consolidated financial statements have
been prepared on the same basis as Sygnet's audited consolidated financial
statements and include all adjustments, which consist only of normal recurring
adjustments, necessary for a fair presentation of the information set forth
therein. Operating results for the nine months ended September 30, 1998 are not
necessarily indicative of results that may be expected for the full year. The
information as set forth below should be read in conjunction with "Use of
Proceeds," "Pro Forma Consolidated Financial Data," "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the consolidated
financial statements and the related notes thereto included elsewhere in this
offering memorandum.

</TABLE>
 
- ------------------------------
(1) Includes the operations of the system acquired in the Erie Acquisition from
    September 30, 1995, the date of acquisition.
 
(2) Includes the operations of the systems acquired in the Horizon Acquisition
    from October 9, 1996, the date of acquisition.
 
(3) Net income (loss) per share applicable to common stockholders for the three
    years ended December 31, 1995 is not provided because there is no meaningful
    data for those periods.
 
(4) Adjusted EBITDA is provided because it is a measure commonly used in the
    telecommunications industry to determine a company's ability to incur or
    service debt. Adjusted EBITDA is not derived according to generally accepted
    accounting principles and should not be considered as an alternative to net
    income, as a measure of performance, or to cash flows, as a measure of
    liquidity. The calculation of Adjusted EBITDA does not include the Company's
    commitments for capital expenditures or payments of debts and should not be
    deemed to represent funds available to the Company.
 
(5) "Earnings" is defined as earnings before extraordinary items and accounting
    changes, interest expense, amortization of deferred financing costs, taxes
    and the portion of rent expense under operating leases representative of
    interest. Fixed charges consist of interest expense, amortization of
    deferred financing costs and a portion of rent expense under operating
    leases representative of interest. For the years ended December 31, 1996 and
    1997 and the nine months ended September 30, 1997 and 1998, earnings were
    insufficient to cover combined fixed charges and preferred stock dividends
    by $4.6 million, $22.7 million, $16.2 million, and $6.6 million,
    respectively.
 
(6) Determined by dividing Sygnet's total ending cellular subscribers for the
    period by the estimated total Pops covered by applicable FCC cellular
    licenses or authorizations held by Sygnet.
 
(7) Churn means the number of cellular subscriber cancellations per period as a
    percentage of the weighted average total cellular subscribers during such
    period. Churn is stated as the average monthly churn rate for the period.
 
(8) Excludes roaming and equipment revenue.
 
(9) Determined by dividing cellular marketing and selling costs by the gross
    cellular subscribers added during such period. Cellular marketing and
    selling costs represent selling expenses and losses incurred on equipment
    sales and equipment rentals.

                     PRO FORMA CONSOLIDATED FINANCIAL DATA
 
    The following unaudited pro forma consolidated condensed financial
statements have been prepared to give effect to the Transactions. The
accompanying unaudited pro forma consolidated condensed statements of operations
of the Company for the year ended December 31, 1997 and the nine months ended
September 30, 1998 give effect to the Transactions as if they occurred on
January 1, 1997. The accompanying unaudited pro forma consolidated condensed
balance sheet as of September 30, 1998 has been prepared as if the Transactions
occurred as of that date. The Sygnet Acquisition has been accounted for using
the purchase method of accounting. The unaudited pro forma consolidated
financial information assumes that all of the Sygnet Notes are tendered in the
Sygnet Note Repurchase and the aggregate purchase price for the Sygnet Notes is
$135.8 million and does not give effect to the Pennsylvania 2 Acquisition.
 
    The unaudited pro forma consolidated condensed financial statements have
been prepared on the basis of certain assumptions that the Company believes are
reasonable, including assumptions relating to the allocation of the
consideration to be paid in the Sygnet Acquisition to the assets and liabilities
acquired, based on estimates of fair values using available information provided
by the management of Sygnet. The unaudited pro forma consolidated condensed
financial statements do not give effect to certain cost savings that the Company
will seek to obtain following the Sygnet Acquisition.
 
    The unaudited pro forma consolidated condensed financial statements and
notes thereto are provided for informational purposes only and do not purport to
be indicative of the results that would have actually been obtained had the
Transactions been completed on the dates indicated or that may be expected to
occur in the future. The unaudited pro forma consolidated financial statements
and notes thereto should be read in conjunction with "Use of Proceeds,"
"Selected Consolidated Financial and Other Data," "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Business-- Markets
and Systems" and the historical financial statements and notes thereto included
elsewhere in this offering memorandum.

(1) To reclassify certain operating revenues and expenses to conform with
    Dobson's presentation.
 
(2) To reflect the impact of the elimination of the depreciation related to the
    sale of the towers and the estimated increase in rental expense attributable
    to the leases, pursuant to the Tower Sale Leaseback.
 
(3) To reflect the additional depreciation and amortization resulting from the
    allocation of the purchase price to property and equipment, cellular license
    acquisition costs and intangible assets. Property and equipment is being
    depreciated over two to ten years, cellular license acquisition costs over
    15 years and intangible assets over five to ten years. The 15 year period
    used for cellular license acquisition costs is based primarily on the
    Company's internal analysis of the recovery period for its cellular
    investments, which indicates that such costs will be recovered through
    operations over a period of not more than 15 years. Other factors considered
    include the competitive nature of the cellular industry, the rate of
    technological change and risk of obsolescence, and the specific terms and
    characteristics of the licenses. See "Risk Factors--Competition" and
    "--Rapid Technological Changes."
 
(4) To reflect (i) the elimination of $29.9 million of interest expense
    (including $1.1 million of amortization of deferred financing costs)
    associated with indebtedness of the Sygnet Notes and the Old Bank Facility
    which will be repaid as part of the Transactions, (ii) $24.5 million of
    interest expense relating to the $200.0 million principal amount of the Old
    Notes, (iii) $33.4 million of interest expense relating to the estimated
    $398.3 million of borrowings under the New Bank Facilities (assuming a
    weighted average interest rate of 8.38%), (iv) $.2 million of interest
    expense relating to the unused principal amount of the New Bank Facilities
    (assuming a commitment fee of .5%), (v) $.8 million of amortization of
    deferred financing costs relating to the estimated $8.2 million of debt
    issuance costs incurred in connection with the offering of the Old Notes and
    (vi) $1.5 million of amortization of deferred financing costs relating to
    the estimated $12.6 million of debt issuance costs incurred in connection
    with the New Bank Facilities.
 
   For each .25% change in the assumed interest rate on the New Bank Facilities,
    interest expense would change by $1.0 million for the year ended December
    31, 1997.
 
(5) To reflect an adjustment to income tax expense for the effects of the
    Transactions, including an income tax benefit for Sygnet's pro forma pre-tax
    loss during the period, assuming a 38% effective tax rate.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    Sygnet owns and operates cellular telephone systems serving a large cluster
of properties with approximately 2.4 million Pops and 166,886 subscribers
located in northeastern Ohio, western Pennsylvania and western New York.
Sygnet's cellular systems are located in Youngstown, Ohio and Erie,
Pennsylvania, and in primarily rural and suburban areas between the Cleveland,
Akron-Canton, Pittsburgh, Buffalo and Rochester metropolitan areas. The
following discussion and analysis is of the historical financial condition and
results of operation of Sygnet and should be read in conjunction with Sygnet's
consolidated financial statements and the notes thereto appearing elsewhere in
this offering memorandum.
 
    Sygnet's operating results have been significantly affected as a result of
the Horizon Acquisition in October 1996 and the Erie Acquisition in September
1995. The systems acquired for $252.9 million in the Horizon Acquisition serve
contiguous markets representing approximately 1.4 million Pops in western
Pennsylvania and New York. The systems acquired in the Erie Acquisition for
$42.5 million represent approximately 282,300 Pops.
 
    Sygnet's revenues primarily consist of (i) service revenue, which includes
charges to the Company's subscribers for access and usage; (ii) roaming revenue,
which includes charges to cellular providers for providing service to their
subscribers in the Company's service areas; and (iii) equipment revenue, from
sales of wireless telephone equipment. There has been an industry trend of
declining average revenue per minute, as competition among service providers has
led to reductions in rates for airtime and subscriptions and other charges and
the Company expects that this trend will continue. The Company believes that the
impact of this trend will be mitigated by increases in the number of cellular
telecommunications subscribers and the number of minutes of usage per
subscriber. There has also been a broad trend in the wireless telecommunications
industry of declining average revenue per subscriber. The Company believes that
the downward trend is primarily the result of the addition of new lower usage
customers who utilize cellular services for personal convenience, security or as
a backup for their traditional landline telephone. Although Sygnet has
experienced a decline in average revenue per subscriber, Sygnet has introduced
new pricing plans, which have increased its number of subscribers.
 
    Roaming accounted for 31.5% and 32.2% of Sygnet's revenue for the year ended
December 31, 1997 and the nine months ended September 30, 1998, respectively.
While the industry trend is to reduce roaming rates, the Company believes that
Sygnet's roaming rates are generally lower than rates offered by others in or
near its systems. However, the Company cannot assure you that this trend will
not materially impact the Company in the future. On a pro forma basis giving
effect to the Horizon Acquisition, roaming yield (roamer service revenue, which
includes airtime, toll charges and surcharges, divided by roaming minutes of
use) was $.57, $.55, $.58 and $.57 per minute for the years ended December 31,
1995, 1996 and 1997 and for the nine months ended September 30, 1998,
respectively.
 
    Included in the Company's roaming revenue for the years ended December 31,
1995, 1996 and 1997 and for the nine months ended September 30, 1997 and
September 30, 1998, respectively, was $.1 million, $.9 million, $3.6 million,
$2.5 million and $4.0 million attributable to Sygnet customers roaming out of
their home areas but in other Sygnet markets.
 
    The Company's primary operating expense categories include cost of service
and equipment, marketing and selling, general and administrative, and
depreciation and amortization.
 
    Cost of service consists primarily of costs associated with billing, amounts
paid for interconnection and call delivery and amounts paid to third-party
cellular providers for providing service to the Company's subscribers when
roaming, offset by the amount billed to the Company's subscribers. Changes in
the interconnection charge rate structure imposed by the FCC or mandated by the
Telecommunications Act may have a material impact on the Company. See
"Business--Regulation."

<PAGE>
    Cost of equipment represents the cost associated with telephone equipment
and accessories sold to customers. In recent years, Sygnet and other cellular
companies have increased the use of discounts on phone equipment and free phone
promotions, as competition between service providers has intensified. As a
result, Sygnet has incurred, and expects to continue to incur, losses on
equipment sales, which have affected marketing and selling costs per gross
additional cellular subscriber. While the Company expects to continue these
discounts and promotions, the Company believes that the use of such promotions
will lead to increased revenue from increases in the number of cellular
subscribers.
 
    Marketing and selling costs primarily consist of advertising costs and
compensation paid to sales personnel and independent agents and retail store
operations' costs. Commissions are paid to direct sales personnel primarily for
the amount of new business generated. Independent sales agents receive
commissions for generating new sales and ongoing sales to existing customers.
 
    General and administrative costs include all infrastructure costs such as
customer support, collections, corporate administration, costs to maintain and
operate cell sites and customer retention costs.
 
    Depreciation and amortization relates primarily to switching and cell site
equipment, customer lists and license costs.
 
RESULTS OF OPERATIONS
 
NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
  1997
 
    REVENUE.  For the nine months ended September 30, 1998, Sygnet's total
revenue increased 22.6% to $76.9 million, from $62.8 million in the first nine
months of 1997. The growth in revenue was the result of continued growth of the
subscriber base and increased roaming revenue generated by additional usage.
 
    Subscriber revenue grew 21.3% to $46.7 million for the nine months ended
September 30, 1998 from $38.5 million in the comparable period in 1997 mainly as
a result of continued subscriber growth, despite a decline in average revenue
per subscriber. Sygnet's number of subscribers increased by 28.2% to 166,886 at
September 30, 1998 from 130,146 at September 30, 1997 due to internal growth. On
a per subscriber basis, average monthly subscriber revenue per subscriber
declined by 6.8% to $33.85 for the nine months ended September 30, 1998 from
$36.33 during the comparable period in 1997. This was due to competitive market
pressures, continuing promotional activity and the changing mix of subscribers
reflecting increasing levels of subscribers who purchase less expensive rate
plans that include packaged minutes of use.
 
    Roamer revenue grew 24.6% to $24.8 million during the nine months ended
September 30, 1998 compared to $19.9 million in the comparable period in 1997.
This increase was mainly a result of increased roaming traffic throughout all of
Sygnet's systems which more than offset the decline in roaming revenue per
minute of use. Roaming minutes of use increased by 30.5% to 43.6 million for the
nine months ended September 30, 1998 from 33.4 million for the comparable period
in 1997. Roaming revenue per minute, including toll, for the nine months ended
September 30, 1998 decreased to $0.57 from $0.59 for the comparable period in
1997. This decrease was mainly a result of increased intrasystem roaming traffic
that is priced lower than other roaming traffic.
 
    Equipment sales revenue increased 39.4% to $4.3 million for the nine months
ended September 30, 1998 from $3.1 million in the comparable period in 1997.
This increase was due mainly to an increased number of telephones and
accessories sold to new customers as well as from additional sales of equipment
to existing customers for retention purposes for which credits are given on the
sales price and reflected in general and administrative costs.
 
    COST OF SERVICES.  Cost of services increased 25.5% to $9.0 million for the
nine months ended September 30, 1998 from $7.2 million for the comparable period
in 1997. This increase was mainly a result of an increase in home subscriber net
roaming costs as well as increased billing and call delivery expenses associated
with the growth in the subscriber base. The increase in net roaming costs is
attributed mostly to
 
                                       36
<PAGE>
increased levels of intrasystem roaming for which rates to customers are lower
than other roaming traffic which has stimulated usage. Partially offsetting this
increase are lower costs to Sygnet for long distance charges and the elimination
of costs associated with a terminated switching agreement. As a percentage of
total revenue, cost of services was 11.7% for the nine months ended September
30, 1998 compared to 11.4% for the same period in 1997.
 
    COST OF EQUIPMENT SALES.  Cost of equipment sales increased 14.5% to $7.8
million for the nine months ended September 30, 1998 from $6.8 million in the
comparable 1997 period. This increase was due mainly to an increased number of
telephones and accessories sold to existing subscribers, as well as equipment
subsidies and sales to new subscribers, offset by a reduction in the average
cost of telephones and accessories.
 
    GENERAL AND ADMINISTRATIVE COSTS.  General and administrative costs
increased 25.7% to $14.7 million for the nine months ended September 30, 1998
from $11.7 million for the comparable period in 1997. This increase was mainly a
result of the growth in the subscriber base which caused an increase in
compensation and increased customer retention costs due to competitive
pressures. As a percentage of total revenues, general and administrative expense
was 19.1% for the nine months ended September 30, 1998 compared to 18.6% for the
same period in 1997.
 
    SELLING AND MARKETING COSTS.  Selling and marketing costs increased 21.3% to
$9.1 million for the nine months ended September 30, 1998 from $7.5 million for
the comparable period in 1997. This increase is mainly due to an increase in new
subscribers added period to period which caused higher compensation and
commission expenses as well as an increase in advertising and promotional
expenses. Selling and marketing cost per gross new subscriber, including
equipment subsidies, decreased by 6.2% to $287 for the nine months ended
September 30, 1998 from $306 for the comparable period in 1997. This was
primarily a result of an improvement in the margin on telephone and accessory
subsidies and sales.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased 1.0%
to $21.3 million for the nine months ended September 30, 1998 from $21.1 million
for the comparable period in 1997 due primarily to the depreciation on higher
levels of fixed assets resulting from capital expenditures for system growth.
This increase more than offset the decrease in depreciation due to certain cell
site equipment obtained in the Horizon Acquisition which become fully
depreciated in April 1998. For the nine months ended September 30, 1998, Sygnet
incurred $11.5 million in capital expenditures, primarily for cell site and
system enhancements.
 
    INTEREST EXPENSE, NET.  Interest expense decreased 4.2% to $21.6 million for
the nine months ended September 30, 1998 from $22.6 million for the comparable
period in 1997. This decrease was primarily a result of a lower level of
borrowing due to the repayment of certain indebtedness with the proceeds from
the sale of common stock.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
    REVENUE.  For 1997, Sygnet's total revenue increased 91.2% to $85.6 million
from $44.8 million for 1996. The growth in revenue was the result of the Horizon
Acquisition, which occurred on October 9, 1996, and continued growth of the
subscriber base.
 
    Subscriber revenue grew by 69.3% to $52.6 million for 1997 from $31.1
million for 1996 mainly as a result of the Horizon Acquisition and continued
subscriber growth. Subscriber revenue, on a pro forma basis giving effect to the
Horizon Acquisition, would have grown by 22.7% due to growth in the subscriber
base, offset by a decline in average revenue per subscriber. Sygnet's
subscribers grew by 34.1% to 142,934 at December 31, 1997 from 106,574 at
December 31, 1996 due mainly to internal growth. On a pro forma basis giving
effect to the Horizon Acquisition, average monthly subscriber revenue per
subscriber would have declined by 7.3% to $35.91 during 1997 from $38.75 in
1996. This was due to the changing mix of
 
                                       37
<PAGE>
subscribers reflecting increasing levels of subscribers purchasing less
expensive rate plans that include limited free minutes of use, increased
promotional activity and competitive market pressures.
 
    Roamer revenue increased 178.6% to $27.0 million during 1997 from $9.7
million for 1996. This increase was mainly a result of the Horizon Acquisition
as well as increased roaming traffic throughout all of Sygnet's systems. On a
pro forma basis giving effect to the Horizon Acquisition, roamer revenue would
have grown by 21.5% due to a greater volume of roaming traffic offset by a
reduction in roaming revenue per minute. Roaming revenue per minute for 1997
would have decreased to $0.58 from $0.59 for 1996 on a pro forma basis giving
effect to the Horizon Acquisition mainly as a result of reductions in roaming
rates with roaming partners.
 
    Equipment sales increased 78.9% to $4.3 million for 1997 compared to $2.4
million for 1996. This increase was due mainly to the Horizon Acquisition, an
increased number of telephones and accessories distributed as new subscriber
acquisitions increased, as well as from additional sales of equipment to
existing customers. On a pro forma basis giving effect to the Horizon
Acquisition, equipment sales for 1997 would have increased 12.4% over 1996.
 
    COST OF SERVICES.  Cost of services increased 82.4% to $10.0 million during
1997 from $5.5 million for 1996 due mainly to the Horizon Acquisition. On a pro
forma basis giving effect to the Horizon Acquisition, cost of services for 1997
would have increased by 12.0% from 1996. This increase was mainly a result of an
increase in billing, call delivery and roaming costs associated with the growth
in the subscriber base, partially offset by lower rates for interconnection and
long distance charges. As a percentage of total revenues, on a pro forma basis
giving effect to the Horizon Acquisition, cost of services was 11.7% in 1997
compared to 12.7% in 1996.
 
    COST OF EQUIPMENT SALES.  Cost of equipment sales increased 66.2% to $9.7
million for 1997 from $5.8 million in 1996. This increase was due mainly to the
Horizon Acquisition and to an increased number of telephones and accessories
distributed as new subscriber acquisitions increased. Sales of equipment to
existing subscribers were also responsible for a portion of this increase. On a
pro forma basis giving effect to the Horizon Acquisition, cost of equipment
sales for 1997 would have increased 18.6% over 1996.
 
    GENERAL AND ADMINISTRATIVE COSTS.  General and administrative costs grew
72.3% to $17.0 million in 1997 from $9.9 million in 1996. This increase was due
primarily to the Horizon Acquisition and an increase in costs due to internal
growth. On a pro forma basis giving effect to the Horizon Acquisition, general
and administrative expenses for 1997 would have increased 19.8% over 1996. This
increase was mainly a result of an increase in compensation, customer retention,
occupancy and maintenance expenses associated with the growth in the subscriber
base as well as the additional cell sites added during 1997. As a percentage of
total revenues, on a pro forma basis giving effect to the Horizon Acquisition,
general and administrative expense would have been 19.8% in 1997 compared to
20.0% in 1996.
 
    SELLING AND MARKETING COSTS.  Selling and marketing costs grew 78.3% to
$10.8 million for 1997 from $6.1 million in 1996. This increase is due to the
Horizon Acquisition and a higher level of new subscribers added period to
period. On a pro forma basis giving effect to the Horizon Acquisition, selling
and marketing costs grew by 12.3% and selling and marketing cost per gross new
subscriber decreased to $291 in 1997 from $324 in 1996 reflecting a decrease in
cost of telephone and accessories in addition to improved operating
efficiencies.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased to
$28.7 million for 1997 from $10.0 million in 1996 due to depreciation on higher
levels of fixed assets resulting from the Horizon Acquisition and purchases of
equipment to enhance systems in existing markets, and amortization of the
license acquired in the Horizon Acquisition. The amortization of the acquired
cellular licenses and subscriber lists contributed $10.3 million to this
increased amortization. For 1997, the Company spent $25.6 million in capital
expenditures, primarily for new cell sites, cell site conversions, and system
growth.
 
                                       38
<PAGE>
    INTEREST EXPENSE, NET.  Interest expense increased to $29.9 million in 1997
from $11.2 million in 1996. This increase was primarily a result of increased
borrowings associated with the Horizon Acquisition.
 
    NET OPERATING LOSSES.  At December 1997, Sygnet had a net operating loss
carryforward of $28.7 million. No benefit of the loss carryforward has been
recorded in 1997. If, in the future, this loss carryforward is utilized, the
related benefits will be recorded.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
    REVENUE.  For 1996, Sygnet's total revenue increased 82.3% to $44.8 million
from $24.6 million for 1995. The growth in revenue was the result of the Horizon
and Erie Acquisitions and continued growth of the subscriber base.
 
    Subscriber revenue grew 80.8% to $31.0 million for 1996 compared to $17.2
million for 1995 mainly as a result of the Horizon and Erie Acquisitions and
continued subscriber growth. Sygnet's subscribers increased to 106,574 at
December 31, 1996 from 44,665 at December 31, 1995 due mainly to the Horizon
Acquisition as well as internal growth. On a pro forma basis giving effect to
the Horizon Acquisition, the subscriber base increased by 36.8% to 106,574 at
December 31, 1996 from 77,891 at December 31, 1995. On a per subscriber basis
giving effect to the Horizon Acquisition, average monthly subscriber revenue
would have declined to $38.75 during 1996 from $41.66 in 1995 due in part to the
changing mix of subscribers reflecting increasing levels of subscribers
purchasing less expensive rate plans that include limited free minutes of use as
well as competitive market pressures.
 
    Roamer revenue increased 132.0% to $9.7 million during 1996 compared to $4.2
million in 1995. This increase was mainly a result of the Horizon and Erie
Acquisitions as well as increased roaming traffic throughout all of Sygnet's
systems. Roamer revenue per minute during 1996 decreased to $.55 from $.57 in
1995. This decrease was due mainly to reductions made to roaming rates received
from other cellular carriers in the first quarter of 1995 which were in effect
for the full year in 1996, mitigated by the effects of the Horizon Acquisition.
 
    Equipment sales increased 58.0% to $2.4 million in 1996 compared to $1.5
million in 1995. This increase was due mainly to the Horizon and Erie
Acquisitions and an increased number of telephones and accessories distributed
as new subscriber acquisitions increased, as well as from additional sales of
equipment to existing customers. Other revenue declined 4.4% to $1.6 million in
1996 from $1.7 million in 1995 as equipment rental revenue continued to decrease
due to the continued phase out of rental programs.
 
    COST OF SERVICES.  Cost of services increased 63.7% to $5.5 million in 1996
from $3.4 million in 1995 due mainly to the Horizon and Erie Acquisitions. Cost
of services decreased to 12.3% of total revenues in 1996 from 13.7% in 1995, as
a result of operating efficiencies gained from the Horizon and Erie
Acquisitions.
 
    COST OF EQUIPMENT SALES.  Cost of equipment sales increased 39.7% to $5.8
million in 1996 from $4.2 million in 1995. This increase was due mainly to the
Horizon and Erie Acquisitions and to an increased number of telephones and
accessories distributed as new subscriber acquisitions increased. The increased
cost of equipment sold resulting from the increase in gross activations was
mitigated by the declining cost to acquire new telephones.
 
    GENERAL AND ADMINISTRATIVE COSTS.  General and administrative costs
increased 77.1% to $9.9 million in 1996 from $5.6 million in 1995. This increase
is due primarily to the Horizon and Erie Acquisitions and the effects of a third
quarter 1995 one time adjustment to the personal property tax accrual resulting
from a substantial decrease in tax rates.
 
    SELLING AND MARKETING COSTS.  Selling and marketing costs increased 97.3% to
$6.1 million in 1996 from $3.1 million in 1995. This increase is due to the
Horizon and Erie Acquisitions and a higher level of
 
                                       39
<PAGE>
new subscribers added period to period. Selling and marketing cost per gross new
subscriber, including equipment subsidies, decreased 10.1% to $310.0 in 1996
from $345.0 for 1995 as a result of a decrease in cost of telephones and
accessories in addition to improved efficiencies.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
187.9% to $10.0 million in 1996 from $3.5 million in 1995 due to depreciation on
higher levels of fixed assets resulting from the Horizon and Erie Acquisitions
and purchases for system growth, and amortization of the licenses acquired in
the Horizon and Erie Acquisitions. The amortization of the acquired cellular
licenses and subscriber lists contributed $3.4 million to this increased
amortization. For 1996, Sygnet spent $10.0 million in capital expenditures,
primarily for new cell sites, cell site conversions, and system growth.
 
    INTEREST EXPENSE, NET.  Interest expense increased to $11.2 million in 1996
from $2.7 million in 1995. This increase was primarily a result of increased
borrowings associated with the Horizon and Erie Acquisitions.
 
    EXTRAORDINARY LOSS.  In October 1996, Sygnet incurred an extraordinary loss
of $1.4 million to write off unamortized financing costs associated with an
extinguished bank credit agreement.
 
IMPACT OF YEAR 2000
 
    The Year 2000 Issue is the result of the inability of some computer programs
to distinguish the year 1900 from the year 2000. Most computer programs and
operating systems were written using two digits to define the applicable year
rather than four digits. This means that any equipment containing computer
programs with time-sensitive software may recognize a date using "00" as the
year 1900 rather than the year 2000. In some instances this could result in
system failures, disruption in operations and possible inaccuracies of data.
 
    Sygnet has substantially completed an inventory of all its systems and
equipment in each market to determine the impact of the Year 2000 Issue. Based
on this inventory, Sygnet has contacted its significant vendors to determine how
their products and services might be affected by the Year 2000 Issue. Generally,
Sygnet is relying upon representations made by the vendors as to their state of
readiness for the Year 2000 Issue. Based on internal evaluations and on
information provided by these vendors certain systems have been upgraded and
tested for Year 2000 compliance. Sygnet estimates that it is 60% complete with
this phase of the project.
 
    Sygnet is placing special emphasis on areas that present a risk of
materially interrupting its revenue stream in the event of a Year 2000 problem.
Presently, it appears three main systems have the potential to materially
interrupt the revenue stream due to the Year 2000 Issue. They are the two
cellular switches, which could prevent calls from being made, and the billing
system, which could prevent Sygnet from billing and subsequently receiving
revenue from its customers. To address this risk, the Northern Telecom switch,
which serves Sygnet's Ohio and Pennsylvania markets, has recently undergone a
software upgrade to a Year 2000 compliant version. Sygnet has monitored testing
of this software in a Year 2000 situation with commonly known critical dates and
has encountered no problems. Accordingly, Sygnet has deemed this system to have
a minimal risk of failure regarding the Year 2000 Issue and will not develop
contingency plans for the Northern Telecom switch unless new information becomes
available that suggests a contingency plan is warranted. The Ericsson switch,
which serves Sygnet's New York market, is expected to have its software upgraded
to a Year 2000 compliant version in the first quarter of 1999. In connection
with the planned upgrade of the New York system, the Company plans to replace
the Ericsson switching equipment with Northern Telecom equipment that is
believed to be Year 2000 compliant. In addition, the upgrade of the billing
system software to a Year 2000 compliant version is expected to be completed in
the first quarter of 1999. The vendor that provides this system has indicated
that Year 2000 compliance testing will be completed by June of 1999. Sygnet has
deemed this system to have a moderate risk of not being able to
 
                                       40
<PAGE>
handle the Year 2000 requirements and a contingency plan is being prepared that
may include selecting a new billing vendor in mid-1999.
 
    The cost of testing and upgrading these systems can not be determined at
this time. Management's current estimate of the cost of becoming Year 2000
compliant is $250,000 or less. This estimate may change significantly downward
or upward as the process continues or if problems arise with either a switch or
billing system. Additionally, this estimate may change substantially if other
systems or vendors are unable to become Year 2000 compliant causing a material
interruption of the revenue stream.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Sygnet has historically relied on internally generated funds to fund debt
service and a substantial portion of its capital expenditures. Bank credit
facilities and equity issuances have been used for additional support of capital
expenditure programs and to fund acquisitions.
 
    Net cash provided by operating activities was $13.5 million for the nine
months ended September 30, 1998 compared to $7.1 million for the comparable
period in 1997. The increase was primarily the result of the increase in
operating income, offset somewhat by a decrease in net working capital. Net cash
provided by operating activities was $9.4 million for 1997 compared to $14.8
million for 1996 and $2.4 million in 1995. This decrease from 1996 to 1997 was
primarily due to interest paid of $30.0 million in 1997 compared to $4.7 million
in 1996, which was offset significantly by the increase in revenue due to growth
in subscribers. The increase from 1995 to 1996 was primarily the result of the
increase in the number of subscribers and their related growth in revenue.
 
    Net cash used in investing activities was $11.1 million for the nine months
ended September 30, 1998 compared to $17.6 million for the comparable period in
1997. In 1998, this activity reflects decreased levels of purchases of property
and equipment primarily for system buildout in addition to proceeds of $300,000
associated with the sale of an undeveloped patent to an officer/shareholder of
Sygnet. In 1997, this activity reflects final payments made in connection with
the Horizon Acquisition and the completion of the buildout of the system
acquired in the Horizon Acquisition. Net cash used in investing activities,
which totaled $25.8 million, $264.2 million and $49.1 million for the years
ended December 31, 1997, 1996 and 1995, respectively, principally related to the
system buildout in 1997, the Horizon Acquisition in 1996 and the Erie
Acquisition in 1995 and capital expenditures required to support the growth of
the business.
 
    Net cash used in financing activities was $2.9 million for the nine months
ended September 30, 1998 compared to $10.0 million provided by financing
activities for the comparable period in 1997 as the combination of reduced
capital expenditures and increased cash flow from operating activities reduced
the need for outside financing. In 1997, this activity included $43.6 million in
net proceeds from the sale of Sygnet's common stock which were used primarily to
redeem the remaining outstanding preferred stock and to reduce amounts
outstanding under Sygnet's Old Bank Facility and fund capital expenditures. Net
cash provided by financing activities was $15.0 million for 1997 compared to
$251.2 million for 1996 and $46.6 million in 1995. The 1996 amount includes
primarily funds received, net of financing cost, from the issuance of the Sygnet
Notes and preferred stock and borrowings under the Old Bank Facility to fund
acquisitions. Dividends of $.3 million and $1.2 million were paid in 1996 and
1995, respectively.
 
    The Company expects its capital expenditures to total approximately $16.0
million for 1999; through September 30, 1998, Sygnet had expended $11.5 million.
Of the amount expected to be made in 1999, $7.5 million is expected to be made
to upgrade the New York system to TDMA IS-136. The amount and timing of capital
expenditures may vary depending on the rate at which the Company expands and
develops its cellular systems and whether the Company consummates additional
acquisitions. In addition, Sygnet expects to borrow $6.0 million under the New
Bank Facilities to close the Pennsylvania 2 Acquisition and additional amounts
to pay any accrued interest under Sygnet's Old Bank Facility and the Sygnet
Notes.
 
                                       41
<PAGE>
    The Company's New Bank Facilities will aggregate $430.0 million, consisting
of a $50.0 million Revolving Credit Facility and $380.0 million of Term Loan
Facilities. Obligations under the New Facilities are secured by a pledge of the
capital stock of Sygnet's operating subsidiary as well as a lien on
substantially all of the assets of Sygnet and its operating subsidiary. The New
Bank Facilities require Sygnet and the Company to maintain certain financial
ratios. The failure to maintain such ratios would constitute an event of
default, notwithstanding Sygnet's ability to meet its debt service obligations.
See "Description of Certain Indebtedness." The ability of Sygnet to borrow under
the New Bank Facilities will be limited by the requirement that, on a quarterly
basis beginning December 31, 2000, the amount available under the New Bank
Facilities will reduce until they terminate.
 
    As part of the Transactions, Sygnet sold to Dobson Tower Company, a wholly
owned subsidiary of Dobson, substantially all of the towers owned by Sygnet for
$25.0 million. Dobson Tower Company has leased these towers back to Sygnet under
an operating lease. The lease is for an initial term of five years, with annual
lease payments of approximately $1.6 million.
 
    On September 30, 1998 after giving pro forma effect to the Transactions, the
Company and its subsidiaries would have approximately $598.2 million of
indebtedness outstanding.
 
    Although the Company cannot provide you any assurance, the Company believes
that, assuming successful implementation of the Company's strategy, including
the further development of Sygnet's cellular systems and significant and
sustained growth in Sygnet's cash flow, borrowings under the New Bank Facilities
and cash flow from operations, will be sufficient to fund the Pennsylvania 2
Acquisition and to satisfy the Company's currently expected capital expenditure,
working capital and debt service obligations. However, the Company will need to
refinance the New Bank Facilities and the Notes at their maturities. The
Company's ability to do so will depend on, among other things, its financial
condition at the time, the restrictions in the instruments governing its
indebtedness and other factors, including market conditions beyond the control

EFFECT OF NEW ACCOUNTING STANDARDS
 
    In June 1997, the FASB issued Statement No. 130, Reporting Comprehensive
Income, which is required to be adopted effective January 1, 1998. This
Statement establishes standards for the reporting and display of comprehensive
income and its components in a full set of general purpose financial statements.
Reclassification of financial statements for earlier periods presented is
required. The implementation of Statement No. 130 did not have a material effect
on Sygnet's financial statements.
 
    In June 1997, the FASB also issued Statement No. 131, Disclosures About
Segments of an Enterprise and Related Information, which is required to be
adopted effective January 1, 1998. This Statement changes the way companies
report segment information in annual financial statements and also requires
those companies to report selected segment information in interim financial
reports to shareholders. The implementation of Statement No. 131 did not have a
material effect on Sygnet's financial statement disclosures.

                                    BUSINESS
 
    Sygnet owns and operates rural and suburban cellular telephone systems
serving a single large cluster of properties with approximately 2.4 million Pops
and 166,886 subscribers in northeastern Ohio, western Pennsylvania and western
New York. The cluster includes Youngstown, Ohio, Erie, Pennsylvania, and
suburban and rural areas between the Cleveland, Akron-Canton, Pittsburgh,
Buffalo and Rochester metropolitan areas. The Company is a wholly owned
subsidiary of Dobson.
 
    Sygnet has grown rapidly through selective acquisitions and internal growth.
Between 1993 and 1997, Sygnet's revenues increased at a compounded annual growth
rate of 56.0% and its Adjusted EBITDA increased at a compounded annual growth
rate of 71.1%. Excluding properties acquired during that period, Sygnet's
revenues increased at a compounded annual growth rate of 23.9% and its Adjusted
EBITDA increased at a compounded annual growth rate of 34.2% over the same
period. In addition, from December 31, 1993 to September 30, 1998, Sygnet's
penetration rate increased from 2.5% to 7.0%. For the nine months ended
September 30, 1998, Sygnet had revenue of $76.9 million, operating income of
$15.1 million and Adjusted EBITDA of $36.4 million.
 
    On December 23, 1998 Dobson/Sygnet Operating Company, a subsidiary of the
Company, merged into Sygnet. Sygnet has established and maintained a strong and
visible local presence. Since the merger, Sygnet's existing local management
will continue to have day-to-day operating authority, with the flexibility to
respond to individual market requirements and to foster a strong sense of
customer service and community spirit. The Company expects to benefit from
synergies resulting from Dobson's centralization of certain functions such as
control of pricing, customer service and marketing, systems design, engineering,
purchasing, financial and administrative functions and from the consolidation of
billing functions. For example, after the Sygnet Acquisition, the Company
expects to consolidate Sygnet's three regional call centers and one of Dobson's
existing call centers. In addition, the Company expects the Sygnet Acquisition
to strengthen and expand Dobson's and Sygnet's existing roaming partner
relationships with AT&T Wireless because certain Sygnet properties are adjacent
to AT&T Wireless properties.
 
    Sygnet's markets are primarily rural and suburban and include a high
concentration of expressway corridors that tend to have a significant amount of
roaming activity. Roaming revenue represented approximately 32% (28% excluding
roaming by Sygnet customers into other Sygnet markets) of Sygnet's total
revenues for both the year ended December 31, 1997 and the nine months ended
September 30, 1998. Sygnet has entered into roaming agreements with operators of
cellular systems in adjoining MSAs and other MSAs which allow customers to roam
at competitive prices which, in certain instances, are comparable to Sygnet's
home area rates. Sygnet's principal roaming partners are AT&T Wireless, AirTouch
and SBC Communications. Sygnet also has roaming agreements with PCS providers,
such as AT&T Wireless and Sprint, to allow the PCS providers' customers with
dual mode telephones to roam in certain Sygnet markets.
 
                                       43

    Through selective acquisitions, Sygnet has created an integrated network of
rural and suburban cellular systems in a contiguous service area. The following
table sets forth certain data with respect to Sygnet's cellular systems:

    Pinellas Communications. On June 8, 1998, Sygnet entered into an agreement
    to purchase Pennsylvania 2 RSA for $6.0 million in cash. Since then, Sygnet
    has been operating Pennsylvania 2 under a management and lease agreement

BUSINESS STRATEGY
 
    The Company's business strategy is to focus on integrating its operations
with Dobson's, increasing its market penetration and further developing its
cellular systems to sustain growth in the Company's cash flows. The principal
elements of the Company's strategy include:
 
    INTEGRATE OPERATIONS WITH DOBSON.  Dobson intends to integrate the
operations of Sygnet with its existing cellular operations to achieve economies
of scale. Management believes that these increased efficiencies will come from
the centralized control of pricing, customer service and marketing, system
design, engineering, purchasing, financial and administrative functions and from
the consolidation of billing functions. For example, the Company expects to
consolidate Sygnet's three regional call centers and one of Dobson's existing
call centers. Following the Sygnet Acquisition, Dobson's subscribers will
approximately double to 329,906 and its total Pops will likewise increase to 5.2
million. Dobson intends to use its increased size to improve its leverage in
negotiating prices and services from third party service providers and equipment
vendors.
 
    EXPAND STRATEGIC RELATIONSHIPS.  The Company intends to continue to maintain
and expand strategic relationships with operators of wireless systems in major
MSAs near the Company's systems. These relationships include roaming agreements
which allow the Company's subscribers to use the system in the neighboring MSA
at favorable rates. Under these agreements, the MSA operator's subscribers
receive similar benefits roaming in the Company's areas. Sygnet has agreements
with the dominant cellular operators in the neighboring MSAs and RSAs, including
AT&T Wireless, AirTouch and SBC Communications. The Company also has agreements
with PCS providers, such as AT&T Wireless and Sprint, to allow
 
                                       44
<PAGE>
the PCS providers' customers with dual mode telephones to roam in certain Sygnet
markets. By entering into these strategic agreements, the Company is able to
increase its roaming revenue and offer its subscribers larger areas in which the
Company's rates apply.
 
    AGGRESSIVE LOCAL MARKETING AND PROMOTION OF CELLULAR SERVICES.  The Company
plans to continue to distinguish Sygnet as the local market's leading cellular
services provider, stressing its service quality, local sales offices and
commitment to the community. Sygnet's sales efforts have been conducted
primarily through its 51 retail outlets and its direct sales force and, to a
lesser extent, through independent agents. The Company believes that, as an
operator with strong local distribution of products and services, Sygnet has an
advantage over its competitors who do not emphasize a local presence or focus on
local market requirements and community involvement. The Company intends to
continue to open new retail outlets and coordinate marketing efforts with
Dobson's centralized marketing department, which should increase efficiencies by
spreading costs over a larger customer base.
 
    TARGETED SALES EFFORTS.  The Company's marketing programs seek to attract
subscribers who are likely to generate high monthly revenue and low churn rates.
The Company will undertake extensive market research to identify and design
marketing programs to attract these subscribers and tailor distinctive rate
plans and roaming rates to emphasize the quality, value and advantage of
Sygnet's cellular service. In addition, the Company intends to maintain Sygnet's
sales force compensation system, which is designed to maximize the acquisition
of these high use, reduced churn subscribers. Sygnet's marketing programs and
compensation systems are designed to increase monthly revenue per subscriber and
lower marketing and selling costs per additional subscriber.
 
    SUPERIOR CUSTOMER SERVICE.  The Company intends to maintain a high level of
customer satisfaction through a variety of techniques, including 24-hour
customer service. The Company will continue to support local customer service
through its direct sales force and its retail stores. Management believes that
Sygnet's emphasis on superior customer service has enabled it to achieve an
average monthly churn rate of 1.3% for the year ended December 31, 1997 and 1.5%
for the nine months ended September 30, 1998.
 
    CONTINUED SYSTEM DEVELOPMENT.  The Company believes that increasing capacity
and upgrading its systems will attract additional subscribers, enhance the use
of its systems by existing subscribers, increase roaming activity and further
enhance the overall efficiency of the network. Sygnet upgraded its Erie,
Youngstown and Pennsylvania markets with TDMA IS-136 digital technology to
enable it to increase roaming (by servicing the increasing number of digital
cellular subscribers and PCS subscribers with dual mode telephones) and provide
enhanced capabilities, including caller ID, longer battery life and zone
billing. Sygnet's digital system covered approximately 84% of its subscribers at
September 30, 1998. The Company plans to upgrade its New York market to TDMA
IS-136 in 1999 which will expand digital coverage to substantially all of its
markets. Since the beginning of 1995, Sygnet has spent approximately $56.2
million to upgrade and expand its network. The Company intends to continue to
improve coverage, increase capacity and build out its systems, and plans to
invest approximately $16.0 million in 1999, which amount includes upgrading its
New York system to TDMA IS-136.
 
MARKETS AND SYSTEMS
 
    Sygnet's operations are conducted in a single large cluster of properties
with approximately 2.4 million Pops and 166,886 subscribers in northeastern
Ohio, western Pennsylvania and western New York. The cluster includes four
markets: the Youngstown market, the Erie market, the Pennsylvania market, and
the New York market. To date, Sygnet has converted 130 of its 181 cell sites to
TDMA IS-136 digital service. The following is a description of Sygnet's cellular
markets.
 
                                       45
<PAGE>
YOUNGSTOWN MARKET
 
    GENERAL.  The Youngstown market is composed of the Youngstown, Ohio MSA, the
Sharon, Pennsylvania MSA and the Ohio 11 RSA. Sygnet initiated cellular
operations in the Youngstown market in 1985 when it acquired its license from
the FCC for the Youngstown, Ohio MSA.
 
    LOCATION.  The Youngstown market covers a contiguous area that is located at
a midway point between Pittsburgh and Cleveland along the Ohio Turnpike and
Interstate 76 and includes Interstate 80, a major transportation access route
from the midwest to New York City.
 
    MARKETING.  The Company operates under the brand name Wilcom Cellular in the
Youngstown market. The Company currently has 18 retail locations and
approximately 22 sales agents in the area.
 
    SYSTEMS.  There are 55 cell sites covering substantially all of the total
Pops in the Youngstown market. The Company has completed upgrading its system in
this area to analog/TDMA IS-136 digital service.
 
ERIE MARKET
 
    GENERAL.  The Erie market is composed of the Erie, Pennsylvania MSA. The
Company initiated cellular operations in the Erie market in September 1995
following the Erie Acquisition.
 
    LOCATION.  The Erie market covers a contiguous area that includes Interstate
90, which connects Buffalo and Cleveland, and Interstate 79, which connects Erie
directly to Pittsburgh.
 
    MARKETING.  The Company operates under the brand name CELLULAR
ONE-Registered Trademark- in the Erie market. The Company currently has eight
retail locations and approximately 12 sales agents in the area.
 
    SYSTEMS.  There are 14 cell sites covering substantially all of the total
Pops in the Erie market. The Company has completed upgrading its system in this
area to analog/TDMA IS-136 digital service.
 
PENNSYLVANIA MARKET
 
    GENERAL.  The Pennsylvania market is composed of Pennsylvania 1 RSA,
Pennsylvania 2 RSA, Pennsylvania 6 RSA and Pennsylvania 7 RSA. Sygnet operated
the Pennsylvania 2 RSA under an interim operating authority which was terminated
upon the granting by the FCC of a permanent license to its present owner,
Pinnellas Communications. On June 8, 1998, Sygnet entered into an agreement with
Pinellas Communications to purchase the Pennsylvania 2 RSA. Since then, Sygnet
has been operating Pennsylvania 2 under a management and lease agreement with
Pinellas Communications, which will continue in effect until the FCC's grant of
the license to Pinellas Communications is no longer subject to reconsideration
or judicial review. The FCC has, however, separately approved the transfer of
the license from Pinellas Communications to Sygnet.
 
    LOCATION.  The Pennsylvania market covers a contiguous area that includes
Interstate 79 and Interstate 80, which link the major population centers in
north-central Pennsylvania, including Pittsburgh and Erie. The Pennsylvania
market also includes Route 60, a recently completed toll road, which serves as
an expressway to Pittsburgh International Airport.
 
    MARKETING.  The Company operates under the brand name CELLULAR
ONE-Registered Trademark- in the Pennsylvania market. The Company currently has
12 retail locations and approximately 15 sales agents in the area.
 
    SYSTEMS.  There are 62 cell sites covering substantially all of the total
Pops in the Pennsylvania market. The Company has substantially completed
upgrading its system in this area to analog/TDMA IS-136 digital service. Upon
acquisition of Pennsylvania 2 RSA from Pinellas, the Company will build out this
system and install TDMA IS-136 digital service.
 
                                       46
<PAGE>
NEW YORK MARKET
 
    GENERAL.  The New York market is composed of the New York 3 RSA. The Company
initiated cellular operations in the New York market in October 1996 following
the Horizon Acquisition.
 
    LOCATION.  The New York market is located in the western part of New York
and includes six counties. The system borders Buffalo and Rochester to the
north, Erie, Pennsylvania to the west and Binghamton/Elmira to the east.
Interstates 90 and 390 and Route 17 run through the New York region. Interstate
90 (the New York Thruway) connects Buffalo, Rochester and Erie. Interstate 390
connects Rochester, Corning, Binghamton and Elmira. Route 17 connects Interstate
390 west to Interstate 90 in Erie.
 
    MARKETING.  The Company operates under the brand name CELLULAR
ONE-Registered Trademark- in the New York market. The Company currently has 13
retail locations and 11 sales agents in the area.
 
    SYSTEMS.  There are 50 cell sites covering substantially all of the total
Pops in the New York market. The Company has not upgraded its system in this
area to digital service. The Company expects to upgrade the New York market to
TDMA IS-136 digital service in 1999.
 
PRODUCTS AND SERVICES
 
    The Company provides a variety of cellular services and products designed to
address a range of consumer, business and personal security needs. In addition
to mobile voice transmission, the Company offers ancillary services such as call
forwarding, call-waiting, three-party conference calling, voice message storage
and retrieval and no-answer transfer. The nature of the services offered by the
Company varies depending upon the market area. The Company also sells cellular
equipment at discount prices and uses free phone promotions to encourage use of
its mobile services.
 
    The Company offers cellular service for a fixed monthly access fee
(accompanied by varying allotments of included or "free" minutes), plus
additional variable charges per minute of use and for custom calling features.
Various pricing programs (which are generally based on one year service
contracts) are utilized. Unlike some of its competitors, the Company designs
rate plans on a market-by-market basis. Generally, these rate plans include
high-volume user plans, medium-volume user plans, basic plans and economy plans.
In general, rate plans which include a higher monthly access fee typically
include a lower usage rate per minute. An ongoing review of equipment and
servicing pricing is maintained to ensure the Company's competitiveness and, as
appropriate, revisions to pricing of service plans and equipment are made to
meet the demands of the local marketplace.
 
    The Company has upgraded substantially all of its cellular systems
(excluding its New York system) to TDMA IS-136 digital technology to enable it
to increase roaming (by servicing the increasing number of digital cellular
subscribers and PCS subscribers with dual mode phones) and provide enhanced
capabilities, including caller ID, longer battery life and zone billing. The
Company expects to upgrade its New York region to TDMA IS-136 digital technology
in 1999. Because its digital switches will be capable of handling both analog
and digital transmission, the Company will be able to continue to offer analog
cellular service to those customers who do not transfer to digital handsets.
Sygnet recently commenced marketing digital cellular services to its customers.
 
CUSTOMER SERVICE
 
    Customer service will remain an essential element of the Company's marketing
and operating philosophy. The Company is committed to attracting new subscribers
and retaining existing subscribers by providing consistently high-quality
customer service. In each of its markets, the Company maintains installation and
repair facilities and a local staff, including a market manager, customer
service representatives and technical and sales representatives. Each cellular
service area handles its own customer-related
 
                                       47
<PAGE>
functions such as customer activations, account adjustments and rate plan
changes. Local offices and installation and repair facilities enable the Company
to service customers better, schedule installations and make repairs. Through
the use of sophisticated, centralized monitoring equipment, the Company will be
able to centrally monitor the technical performance of its cellular service
areas.
 
    In addition, the Company's customers are able to report cellular telephone
service or account problems 24-hours a day to a call service center on a
toll-free access number (with no airtime charge). As soon as practicable after
the Sygnet Acquisition, the Company expects to consolidate Sygnet's three
regional call centers and one of Dobson's existing call centers. Management
believes its emphasis on customer service affords it a competitive advantage
over its large competitors.
 
SALES, MARKETING AND DISTRIBUTION
 
    The Company will continue to focus its marketing program on attracting
subscribers who are likely to generate high monthly revenue and low churn rates.
The Company undertakes extensive market research to identify and design
marketing programs to attract these subscribers and tailor distinctive rate
plans and roaming rates to emphasize the quality, value and the advantage of the
Company's cellular service. The Company has established marketing alliances with
neighboring cellular systems to create larger "home rate" areas and to
effectively expand the Company's footprint in order to increase its roaming
revenue and to attract new subscribers. The Company markets its service
offerings primarily through its direct sales force and Company-owned retail
stores. The Company also uses a network of dealers and other agents, such as
electronics stores, car dealerships and department stores. In addition to these
traditional channels, the Company's marketing team evaluates other, less
traditional, methods of distributing the Company's services and products, such
as targeted telemarketing and direct mail programs.
 
    The Company will continue to market its cellular products and services under
the brand names Wilcom Cellular, which has strong regional recognition in the
Youngstown region, and CELLULAR ONE-Registered Trademark-, one of the most
recognized brand names in the cellular industry. The national advertising
campaign conducted by the Cellular One Group enhances the Company's advertising
exposure at a fraction of the cost of what could be achieved by the Company
alone. See "--Service Marks."
 
    Management trains and compensates its sales force in a manner designed to
stress the importance of customer service, high penetration levels and minimum
acquisition costs per subscriber. The Company believes that its direct sales
force is better able to select and screen new subscribers and select pricing
plans that realistically match subscriber means and needs than are independent
agents. In addition, the Company motivates its direct sales force to sell
appropriate rate plans to subscribers, thereby reducing churn, by linking
payment of commissions to subscriber retention. As a result, the Company
believes its use of a direct sales force keeps marketing costs low both
directly, because commissions are lower, and indirectly, because subscriber
retention is higher than when independent agents are used.
 
    The Company believes that the after-sale telemarketing program conducted by
its sales force and customer service personnel helps to reduce its churn rate.
This program enhances customer loyalty and allows the sales staff to check
customer satisfaction as well as to offer additional calling features, such as
voicemail, call waiting and call forwarding.
 
    At September 30, 1998, Sygnet had 24 retail stores and 27 other retail
outlets. The retail stores range in size from 1,500 square feet to 5,000 square
feet, and each retail store is fully equipped to handle customer service and
telephone maintenance and installation. Some of these stores are also authorized
warranty repair centers. The Company's stores provide subscriber-friendly retail
environments (extended hours, large selection, an expert sales staff and
convenient locations) which make the sales process quick and easy for the
subscriber. The retail outlets, other than retail stores, consist of kiosks in
malls and other stores.
 
                                       48
<PAGE>
ROAMING
 
    The Company believes that regional roaming is an important service component
for many subscribers. The Company believes that roaming will continue to be a
substantial source of revenue for the Company due, in part, to the fact that
Sygnet's cellular system is located in rural and suburban areas with a high
concentration of commuting customers and expressway corridors that tend to
result in a significant amount of roaming activity. Sygnet has entered into
roaming agreements with operators of cellular systems in adjoining MSAs and RSAs
and others which provide for roaming rates that allow customers to roam at
competitive prices which, in certain instances, are comparable to home area
rates. The Company believes this increases usage on all wireless systems,
including the Company's. Sygnet's principal roaming partners are AT&T Wireless,
AirTouch and SBC Communications. Sygnet also has agreements with PCS providers,
including AT&T Wireless and Sprint, to allow PCS providers' customers with dual
mode phones to roam in certain Sygnet markets.
 
    Sygnet has agreements with NACN, which is the largest wireless telephone
network system in the world linking cellular operators throughout the United
States and Canada. NACN connects key areas across North America so that
customers can use their cellular phones to place and receive calls in these
areas as easily as they do in their home areas. Through NACN, customers receive
calls automatically without the use of complicated roaming codes as they roam in
more than 5,000 cities and towns in the United States and Canada. In addition,
special services such as call forwarding and call waiting automatically follow
subscribers as they travel. While the industry trend is to reduce roaming rates,
the Company believes that Sygnet's roaming rates are generally lower than the
rates offered by others in or near its systems and that Sygnet's roaming rates
are not materially impacted by this trend. The Company, however, can provide no
assurance that this trend will not materially impact the Company in the future.
 
TECHNOLOGY AND SYSTEM DEVELOPMENT
 
    OVERVIEW.  Historically, most cellular services have transmitted voice and
data signals over analog-based systems, which use one continuous electronic
signal that varies in amplitude or frequency over a single radio channel.
Digital systems, on the other hand, convert voice or data signals into a stream
of digits that is compressed before transmission, enabling a single radio
channel to carry multiple simultaneous signal transmissions. This enhanced
capacity, along with enhancements in digital protocols, allows digital-based
wireless technologies to offer new and enhanced services, such as greater call
privacy and single number (or "find me") service, and more robust data
transmission features, such as "mobile office" applications (including
facsimile, electronic mail and connecting notebook computers with computer/data
networks).
 
    While digital technology serves generally to reduce transmission
interference relative to analog technology, capacity limitations in the 8
kilobit cellular digital handsets now deployed by most digital cellular
operators also cause a perceptible decline in transmission quality. This gap in
transmission quality has proven to be a significant barrier to cellular
operators seeking to switch their customers from analog to digital service.
Enhanced 13 kilobit digital handsets are now available for digital cellular
systems. These new handsets offer improved digital transmission.
 
    SYSTEM DEVELOPMENT.  At September 30, 1998, the Sygnet network included a
Northern Telecom cellular switch (which presently serves all areas but the New
York market) and an Ericsson cellular switch (which presently serves the New
York market), 181 cell sites and a large microwave network with 151 links.
Substantially all of the Sygnet system (excluding its New York system) supports
AMPS and TDMA services. As of September 30, 1998, Sygnet had converted 130 of
its 181 cell sites to TDMA IS-136 digital technology. The Company intends to
upgrade its New York market to TDMA IS-136 digital technology with Northern
Telecom equipment in 1999. The Company develops or builds out its cellular
service areas by adding channels to existing cell sites and by building new cell
sites with an emphasis on improving coverage for hand-held phones in
heavily-trafficked areas. Such development is designed to increase
 
                                       49
<PAGE>
capacity and to improve coverage in response to projected subscriber demand and
in response to competitive factors. Projected subscriber demand is calculated
for each cellular service area on a cell-by-cell basis. Sygnet has historically
met such demand through a combination of augmenting channel capacity in existing
cell sites and building new cell sites.
 
    System expansion by cell site construction is expected to enable the Company
to continue to add and retain subscribers, enhance subscriber use of the
systems, increase roamer traffic due to the larger geographic area covered by
the cellular network and further enhance the overall efficiency of the network.
The Company believes that the increased cellular coverage will have a positive
impact on market penetration and subscriber usage.
 
    Sygnet owns 124 of the 134 cellular towers it uses. In connection with the
Sygnet Acquisition, Sygnet intends to sell substantially all of these towers to
Dobson Tower Company, a subsidiary of Dobson in the Tower Sale Leaseback. See

    DIGITAL TECHNOLOGY.  Digital signal transmission is accomplished through the
use of frequency management technologies, or "protocols." These protocols
"manage" the radio channel either by dividing it into distinct time slots (TDMA)
or by assigning specific coding instructions to each packet of digitized data
that comprises a signal (CDMA). While the FCC has mandated that licensed
cellular systems in the U.S. must utilize compatible analog signaling protocols,
at present there is no required universal digital signaling protocol. Because
the CDMA and TDMA protocols are incompatible, a subscriber of a system that
relies on TDMA technology, for example, will be unable to use his handset when
traveling in an area served only by CDMA, unless he carries a dual-mode handset
(which is not yet available) that permits the subscriber to use the cellular
system in that area. However, the FCC or industry organizations may decide to
move toward a universal digital switching protocol in the future.
 
    Over the next decade, it is expected that many cellular systems will convert
from analog to digital technology. This conversion is due in part to capacity
constraints in many of the largest cellular markets, such as New York, Los
Angeles and Chicago. As carriers reach limited capacity levels, certain calls
may be unable to be completed, especially during peak hours. Digital technology
increases system capacity and offers other advantages, often including improved
overall average signal quality, improved call security, potentially lower
incremental costs for additional subscribers and the ability to provide data
transmission services. The conversion from analog to digital technology is
expected to be an industry-wide process that will take a number of years to
complete. While management does not believe that its network will experience
capacity constraints in the foreseeable future that would require converting its
network from analog to digital technology, it has converted its systems, other
than its New York systems, to TDMA IS-136 digital service so that its
subscribers will enjoy the added benefits of digital technology, and the Company
will benefit from increased roamer revenue (by servicing the increasing number
of digital cellular subscribers and PCS subscribers with dual mode phones).
 
    INFORMATION SYSTEMS.  Home subscriber billing functions for the Company's
cellular operations are provided by International Telecommunications Data
Service ("ITDS"), which is also the primary provider of billing services for
Dobson. Proprietary software furnished by ITDS serves all functions of billing
for the corporate and retail locations. All administrative and customer
maintenance functions are handled in-house with invoice processing and printing
handled by ITDS. The Company uses complementing software to the billing system
allowing the use of credit, collection, and switch interfaces.
 
SERVICE MARKS
 
    In its cellular telephone business, Sygnet is currently licensed to use the
CELLULAR ONE-Registered Trademark- service mark in its Erie, New York and
Pennsylvania regions. CELLULAR ONE-Registered Trademark- is a registered service
mark with the U.S. Patent and Trademark Office. The service mark is owned by
Cellular One Group, a Delaware general partnership of Cellular One Marketing,
Inc., a subsidiary of SWBM, together with Cellular One Development, Inc., a
subsidiary of AT&T Wireless, and Vanguard. The Company uses the CELLULAR
 
                                       50
<PAGE>
ONE-Registered Trademark- service mark to identify and promote its cellular
telephone service pursuant to licensing agreements with Cellular One Group (the
"Licensor"). Licensing and advertising fees are determined based upon the
population of the licensed areas. The licensing agreements require Sygnet to
provide high-quality cellular telephone service to its customers and to maintain
a certain minimum overall customer satisfaction rating in surveys commissioned
by the Licensor. The licensing agreements which Sygnet has entered into are for
original five-year terms that expire beginning in 2001. These agreements may be
renewed at Sygnet's option, subject to the satisfaction of certain operating
standards, for two additional five-year terms. See "Risk Factors--Reliance on
Use of Third-Party Service Mark."
 
    The Company currently operates in the Youngstown region under the
unregistered tradename "Wilcom Cellular." The Company also uses "Sygnet
Wireless, Inc." and "Sygnet Communications, Inc." as unregistered tradenames.
 
COMPETITION
 
    The Company competes with various companies in each of its markets. Overall,
the Company competes against four distinct cellular system operators.
 
    The following chart lists the Company's cellular competitors:

</TABLE>
 
    PCS licenses in the Company's markets have been awarded to Ameritech
Wireless, Aerial Communications, AT&T Wireless, Devon Mobile Communications, New
England Wireless, Nextwave and Omnipoint. To date no PCS licensee is actively
marketing PCS services in the Company's markets, although certain licensees have
built out portions of the highway corridors.
 
    The wireless telecommunications industry is experiencing significant
technological change, as evidenced by the increasing pace of improvements in the
capacity and quality of digital technology, shorter cycles for new products and
enhancements, and changes in consumer preferences and expectations. Accordingly,
the Company expects competition in the wireless telecommunications business to
be dynamic and intense as a result of the entrance of new competitors and the
development of new technologies, products and services.
 
    Each of the markets in which the Company competes is served by other two-way
wireless service providers, including licensed cellular and PCS operators. Many
of these competitors have been operating for a number of years, currently serve
a substantial subscriber base and have significantly greater financial and
technical resources than those available to the Company. Some competitors may
market other services, such as long distance, landline local exchange services
and internet access, with their wireless telecommunication service offerings.
Several of the Company's competitors are operating, or planning to operate,
through joint ventures and affiliation arrangements, wireless telecommunications
systems that encompass most of the United States.
 
    In each of its markets, the Company competes primarily against one other
facilities-based cellular carrier. Competition for customers between cellular
licensees is based principally upon price, the services and enhancements
offered, the technical quality of the cellular system, customer service, system
coverage and capacity. Such competition may increase to the extent that licenses
are transferred from smaller, stand-alone operators to larger, better
capitalized and more experienced cellular operators that may be able to offer
consumers certain network advantages.
 
                                       51
<PAGE>
    Cellular carriers also face to a lesser extent competition from PCS, ESMR
and mobile satellite service ("MSS") systems, as well as from resellers of these
services and cellular service. In the future, cellular operators may also
compete more directly with traditional landline telephone service providers.
Continuing technological advances in telecommunications make it impossible to
predict the extent of future competition. However, due to the depth and breadth
of these competitive services offered by operators using these other
technologies, such competition could be significant and is expected to become
more intense.
 
    The FCC requires that all cellular system operators provide service to
resellers on a nondiscriminatory basis. A reseller provides cellular service to
customers but does not hold an FCC license or own cellular facilities. Instead,
the reseller buys blocks of cellular telephone numbers from a licensed carrier
and resells service through its own distribution network to the public.
Therefore, a reseller may be both a customer of a cellular licensee's services
and a competitor of that licensee. Several well-known telecommunications
companies resell cellular service as a complement to their long distance, local
telephone, paging, cable television or internet offerings.
 
    The most likely future source of direct competition to cellular providers in
the near term from a new technology is broadband PCS. Broadband PCS services
consist of wireless two-way telecommunications services for voice, data and
other transmissions employing digital micro-cellular technology. PCS operates in
the 1850 to 1990 MHz band. PCS technology utilizes a network of small,
low-powered transceivers placed throughout a neighborhood, business complex,
community or metropolitan area to provide customers with mobile and portable
voice and data communications. Many PCS licensees that will compete with the
Company have access to substantial capital resources. In addition, many of these
companies or their predecessors and affiliates already operate large cellular
telephone systems and thus bring significant wireless experience.
 
    ESMR is a wireless communications service supplied by converting analog SMR
services into an integrated, digital transmission system. The ESMR system
incorporates characteristics of cellular technology, including multiple low
power transmitters and interconnection with the landline telephone network. ESMR
service providers, such as Nextel, may compete with analog cellular service by
providing high quality digital communication technology, lower rates, enhanced
privacy and additional features such as electronic mail and built-in paging.
ESMR handsets are likely to be more expensive than cellular telephones.
 
    A consortium of telecommunications providers known as American Mobile
Satellite Corporation has been licensed by the FCC to provide MSS and is
currently providing such services. The FCC has also licensed four entities to
provide MSS as low earth-orbit satellite-based systems. One such licensee,
controlled by Motorola, operates a low earth-orbit satellite-based system called
"Iridium" and recently initiated such service in some markets. None of the other
licensees have yet launched MSS service. Other proposals for MSS are pending
before the FCC. The FCC is developing rules for these services and international
and foreign regulatory authorities must also approve aspects of some MSS
services. Mobile satellite systems could augment or replace communications
within land-based cellular systems. While the Company may experience increased
competition from low earth-orbit satellite-based systems in the future, to date,
such systems have not affected the Company's operations.
 
    The commercial development and deployment of most of these new technologies
remain in an early phase. The Company expects this activity to be focused
initially in relatively large markets in view of the substantial costs involved
in building and launching systems using these technologies. The Company believes
that it can effectively face this competition from its position as an incumbent
in the cellular industry with a high quality network, an extensive footprint
that is not capacity constrained, strong distribution channels, superior
customer service capabilities and an experienced management team. Since the
Company operates in medium to small markets, the new entrants may be unable to
offer wireless service at competitive rates in many of the Company's markets in
the near term. The extensive capital
 
                                       52
<PAGE>
expenditures required to deploy infrastructure are more readily justifiable from
an economic standpoint in larger, more densely populated urban areas, than in
the rural areas in which the Company operates.
 
REGULATION
 
    OVERVIEW.  The wireless telecommunications industry is subject to extensive
governmental regulation on the federal level and to varying degrees on the state
level. Many aspects of such regulation have been impacted by the enactment of
the Telecommunications Act and have been the subject of administrative
rulemakings that are significant to the Company. The following is a summary of
the federal laws and regulations that materially affect the cellular
communications industry and a description of certain state laws. This section
does not purport to be a summary of all present and proposed federal, state and
local regulations and legislation relating to the cellular communications
industry.
 
    FEDERAL REGULATION.  The licensing, construction, modification, operation,
ownership and acquisition of cellular telephone systems are subject to
regulations and policies of the FCC under the Communications Act of 1934, as
amended (the "Communications Act"). The FCC has promulgated rules and
regulations governing, among other things, applications to construct and operate
cellular communications systems, applications to transfer control of or assign
cellular licenses and technical and operational standards for the operation of
cellular systems (such as maximum power and antenna height).
 
    The FCC licenses cellular systems in accordance with 734 geographically
defined market areas comprising 306 MSAs and 428 RSAs. In each market, the
frequencies allocated for cellular telephone use are divided into two equal 25
MHz blocks and designated as wireline and non-wireline. Apart from the different
frequency blocks, there is no technical difference between wireline and
non-wireline cellular systems and the operational requirements imposed on each
by the FCC are the same. However, no entity may own, directly or indirectly,
more than a 5% interest in both systems in any one MSA or RSA, unless such
ownership will not pose a substantial threat to competition, and no entity may,
directly or indirectly, own a controlling interest in, or otherwise have the
ability to control, both such systems. The FCC may prohibit or impose conditions
on transfers of licenses. In addition, under FCC rules, no person may have an
attributable interest in a total of more than 45 MHz of licensed, broadband PCS,
cellular and ESMR spectrum regulated as Commercial Mobile Radio Services
("CMRS") with significant overlap in any geographic area (significant overlap
will occur when at least 10% of the population of the PCS licensed service areas
is within the CGSA (as defined below) and/or the ESMR service area).
 
    Under FCC rules, the authorized service area of a cellular provider in each
of its markets is referred to as the "Cellular Geographic Service Area" or
"CGSA." The CGSA may conform exactly with the boundaries of the FCC designated
MSA or RSA, or it may be larger or smaller, subject to certain minimum service
requirements. A cellular licensee has the exclusive right to expand its CGSA
boundaries within the licensee's MSA or RSA for a period of five years after
grant of the licensee's initial construction permit. At the end of this
five-year build-out period, however, any entity may apply to serve portions of
the MSA or RSA of at least 50 square miles in size outside the licensee's then
designated CGSA. Sygnet's five year buildout period has expired in all of its
existing markets, with the exception of Pennsylvania 2 RSA.
 
    Cellular service providers also must satisfy a variety of FCC requirements
relating to technical and reporting matters. One such requirement is the
coordination of proposed frequency usage with adjacent cellular users,
permittees and licensees in order to avoid interference between adjacent
systems. In addition, the height and power of base station transmitting
facilities and the type of signals they emit must fall within specified
parameters. The Company is obligated to pay certain annual regulatory fees to
the FCC in connection with its cellular operations, as well as other fees
necessary to support centralized numbering, administration of telephone numbers,
the provision of telecommunications relay services for the hearing-impaired and
applications' filing fees.
 
    The Communications Act requires prior FCC approval for transfers to or from
the Company of a controlling interest in any license or construction permit, or
any rights thereunder. All of the applications
 
                                       53
<PAGE>
requesting the FCC's approval for the transfers of control and license
assignments associated with the Sygnet Acquisition have been granted by the FCC.
Although there can be no assurance that any future requests for approval of
applications filed will be approved or acted upon in a timely manner by the FCC,
the Company has no reason to believe such requests or applications would not be
approved or granted in due course.
 
    The FCC also regulates a number of other aspects of the cellular business.
For example, the FCC regulates cellular resale practices and recently extended
the resale requirement to broadband PCS and ESMR licensees. Cellular, PCS and
ESMR providers may not restrict any customer's resale of their services or
unreasonably discriminate against resellers of their services. All resale
obligations for cellular, broadband PCS and ESMR operators will terminate on
November 24, 2002. The FCC has also adopted requirements for cellular and other
providers of two-way voice services to implement basic and enhanced 911
services. These services provide emergency service providers with the ability to
better identify and locate callers using wireless services, including callers
using special devices for the hearing impaired. The Company's implementation of
these services is scheduled to occur in several stages ending in October 2001.
Cellular and PCS carriers are also required to provide law enforcement agencies
with capacity to support lawful wiretaps by March 12, 2001 and technical
assistance for wiretaps by June 30, 2000. These wireless 911 and law enforcement
requirements may create additional capital obligations for the Company to make
necessary system changes.
 
    In addition, the FCC regulates the ancillary service offerings that cellular
and PCS licensees can provide and recently revised its rules to permit cellular,
broadband PCS, paging and ESMR licensees to offer fixed services on a co-primary
basis along with mobile services. This rule change may facilitate the provision
of wireless local loop service, which involves the use of wireless links to
provide local telephone service by cellular licensees, as well as broadband PCS
and ESMR licensees. In this regard, the FCC also recently adopted telephone
number portability rules for local exchange carriers, as well as cellular,
broadband PCS and ESMR licensees, that could facilitate the development of local
exchange competition, including wireless local loop service. The new number
portability rules generally require cellular, broadband PCS and ESMR licensees
to have the capability to deliver calls from their systems to ported numbers by
December 31, 1998 and offer number portability and roaming to ported numbers by
March 31, 2000. These requirements may result in added capital expenditures for
the Company to make necessary system changes, although the Company currently has
no plans for any such expenditures.
 
    Initial cellular licenses are generally granted for terms of ten years,
beginning on the date of the grant of the initial operating authority, and are
renewable upon application to the FCC. Sygnet's cellular licenses expire at
various dates beginning in October 2000. Licenses may be revoked and license
renewal applications denied for cause after appropriate notice and hearing. Near
the conclusion of the license term, licensees must file applications for renewal
of licenses to obtain authority to operate for up to an additional 10-year term.
The FCC will award a renewal expectancy to a cellular licensee that meets
certain standards of past performance. If the existing licensee receives a
renewal expectancy, it is very likely that the existing licensee's cellular
license will be renewed without becoming subject to competing applications. To
receive a renewal expectancy, a licensee must show that it has provided
"substantial" service during its past license term, and has substantially
complied with applicable FCC rules and policies and the Communications Act.
"Substantial" service is defined as service which is sound, favorable and
substantially above a level of mediocre service that might only minimally
warrant renewal. If the existing licensee does not receive a renewal expectancy,
competing applications for the license will be accepted by the FCC and the
license may be awarded to another entity.
 
    In order to increase competition in wireless communications, promote
improved quality and service and make available the widest possible range of
wireless services, federal legislation was enacted directing the FCC to allocate
radio frequency spectrum for PCS by competitive bidding. A PCS system operates
under a protected geographic service area license granted by the FCC for either
an MTA or BTA on one of six frequency blocks allocated for broadband PCS
service. The FCC has divided the United States and its
 
                                       54
<PAGE>
possessions and territories into PCS markets made up of 493 BTAs and 51 MTAs. As
many as six licensees will compete in each PCS service area. The FCC has
allocated 120 MHz of radio spectrum in the 2 GHz band for licensed broadband PCS
services. The FCC divided the 120 MHz of spectrum into six individual blocks,
each of which is allocated to serve either MTAs or BTAs. The spectrum allocation
includes two 30 MHz blocks (A and B Blocks) licensed for each of the 51 MTAs,
one 30 MHz block (C Block) licensed for each of the 493 BTAs, and three 10 MHz
blocks (D, E and F Blocks) licensed for each of the 493 BTAs, a total of more
than 2,000 licenses.
 
    Applications for FCC authority may be denied and in extreme cases licenses
may be revoked if the FCC finds that an entity lacks the requisite "character"
qualifications to be a licensee. In making the determination, the FCC considers
whether an applicant or licensee has been the subject of adverse findings in a
judicial or administrative proceeding involving felonies, the possession or sale
of unlawful drugs, fraud, antitrust violations or unfair competition, employment
discrimination, misrepresentations to the FCC or other government agencies, or
serious violations of the Communications Act or FCC regulations.
 
    If the FCC determines that the public interest would be served, it may
revoke the Company's cellular licenses or require an ownership restructuring if
greater than 25 percent of the Company's equity is owned of record or voted by
aliens or their representatives, a foreign government or its representative, or
any corporation organized under the laws of a foreign country. The FCC will
generally permit additional indirect ownership in excess of the statutory 25
percent benchmark where that interest is to be held by an entity or entities
from member countries of the World Trade Organization ("WTO"). For investors
from non-WTO countries, however, the FCC will determine whether the home country
of the foreign investor extends reciprocal treatment called "equivalent
competitive opportunities" to U.S. entities. If such opportunities do not exist,
it is unlikely that the FCC will permit investment beyond the 25 percent
benchmark. These restrictions could adversely affect the Company's ability to
attract additional equity financing.
 
    Interconnection charges paid to local exchange carriers are a major
component of the Company's cost of service. Changes in the interconnection
charge rate structure imposed by the FCC or mandated by the Telecommunications
Act may have a material impact on the Company.
 
    The Telecommunications Act, which makes significant changes to the
Communications Act and terminated the antitrust consent decree applicable to the
RBOCs, affects the telecommunications industry. This legislation, among other
things, affects competition for local telecommunications services,
interconnection arrangements for carriers, universal service funding and the
provision of interexchange services.
 
    The Telecommunications Act requires state public utilities commissions
and/or the FCC to implement policies that mandate reciprocal compensation
between local exchange carriers, a category that will, for these purposes,
include cellular carriers, for interconnection services at rates more closely
related to cost. On August 1, 1996, the FCC adopted rules implementing the
interconnection policies imposed by the Telecommunications Act. Various aspects
of the order not directly related to interconnection between wireless carriers
and local exchange carriers are currently being reviewed by the U.S. Supreme
Court and the FCC's orders are currently subject to a federal appellate court
stay. If the FCC's rules are upheld on appeal, such action could result in
further reductions of the Company's interconnection expenses.
 
    The Telecommunications Act requires the FCC to adopt rules that require
interstate communications carriers, including cellular carriers, to "make an
equitable and non-discriminatory contribution" to a universal service fund that
reimburses communications carriers that provide basic communications services to
users who receive services at subsidized rates. These rules could result in
increased costs for the Company's cellular operations. The Telecommunications
Act also eases the restrictions on the provision of interexchange telephone
services by wireless carriers affiliated with RBOCs. RBOC-related wireless
carriers have interpreted the legislation to permit immediate provision of long
distance call delivery for their cellular customers.
 
                                       55
<PAGE>
    The Telecommunications Act specifically exempts all cellular carriers from
the obligation to provide equal access to interstate long distance carriers.
However, the Telecommunications Act gives the FCC the authority to impose rules
to require unblocked access through carrier identification codes or 800/888
numbers, so that cellular subscribers are not denied access to the long distance
carrier of their choosing, if the FCC determines that the public interest so
requires. The Company currently provides "dial around" equal access to all of
its customers.
 
    The Telecommunications Act also imposes restrictions on a telecommunications
carrier's use of customer proprietary network information. FCC rules
implementing these restrictions could impose new costly obligations on the
Company and impose burdens on its current marketing activities.
 
    The overall impact of the Telecommunications Act on the business of the
Company is unclear and will likely remain so for the foreseeable future. The new
limitations on local zoning requirements may facilitate the construction of new
cell sites and related facilities. See "--State, Local and Other Regulation."
However, other provisions of the statute relating to interconnection, telephone
number portability, equal access, use of customer proprietary network
information and resale could subject the Company to additional costs and
increased competition.
 
    STATE, LOCAL AND OTHER REGULATION.  The Communications Act preempts state or
local regulation of the entry of, or the rates charged by, any commercial mobile
service or any private mobile service provider, which includes cellular
telephone service providers. The FCC has denied the petition of eight states to
continue their rate regulation authority, including authority over cellular
operators. As a practical matter, the Company is free to establish rates and
offer new products and service with a minimum of regulatory requirements. The
three states in which the Company will operate upon completion of the Sygnet
Acquisition maintain nominal oversight jurisdiction, primarily focusing upon
prior approval of acquisitions and transfers and resolution of customer
complaints.
 
    The location and construction of cellular transmitter towers and antennas
are subject to FCC and Federal Aviation Administration regulations and are
subject to federal, state and local environmental regulation, as well as state
or local zoning, land use and other regulation. Before a system can be put into
commercial operation, the grantee of a construction permit must obtain all
necessary zoning and building permit approvals for the cell sites and microwave
tower locations and must secure state certification, if required. The time
needed to obtain zoning approvals and requisite state permits varies from market
to market and state to state. Likewise, variations exist in local zoning
processes. In addition, any proposed site must comply with the FCC's
environmental rules.
 
    Zoning and planning regulation may become more restrictive in the future as
many broadband PCS carriers are now seeking sites for network construction. The
Telecommunications Act provides limited relief from state and local laws that
arbitrarily restrict the expansion of personal wireless services, which include
cellular, PCS and ESMR systems. For example, under the Telecommunications Act,
localities are now precluded from denying zoning approval for cell sites based
upon electromagnetic emission concerns, if the cellular operator's system
complies with FCC emissions standards. In addition, localities are prohibited
from adopting zoning requirements that prohibit or have the effect of
prohibiting personal wireless services, or that discriminate between
"functionally equivalent" services. Notwithstanding these new requirements,
wireless carriers have had various degrees of success in challenging offensive
zoning requirements and it is still unclear whether the costs of expanding
cellular systems by adding cell sites will increase and whether significant
delays will be experienced due to local zoning regulations.
 
    The Company can provide no assurance that any state or local regulatory
requirements currently applicable to the Company's systems will not be changed
in the future or that regulatory requirements will not be adopted in those
states and localities which currently have none.
 
    FUTURE REGULATION.  From time to time, legislation that could affect the
Company, either beneficially or adversely, is proposed by federal or state
legislators. There can be no assurance that federal or state
 
                                       56
<PAGE>
legislation will not be enacted, or that regulations will not be adopted or
actions taken by the FCC or state regulatory authorities, that might adversely
affect the business of the Company. Changes such as the allocation by the FCC of
radio spectrum to services that compete with the Company's business could
adversely affect the Company's operating results.
 
EMPLOYEES AND AGENTS
 
    As of September 30, 1998, Sygnet had approximately 455 employees and had
agreements with more than 60 independent sales agents. None of Sygnet's
employees is represented by a labor organization, and the Company considers
Sygnet's employee relations to be good.
 
PROPERTIES
 
    The Company maintains its headquarters in Oklahoma City, Oklahoma. Sygnet
owns office buildings in Youngstown and Warren, Ohio and land for a proposed
office site in Boardman, Ohio. As of September 30, 1998, the Company's cellular
operations leased 55 and owned 2 retail sales and administrative offices. The
Company anticipates that it will review these leases from time to time and may,
in the future, lease or acquire new facilities as needed. The Company does not
anticipate that it will encounter any material difficulties in meeting its
future needs for any leased space. The Company owned 4 cell sites and 124 towers
and leased 177 cell sites and 10 towers as of September 30, 1998. As part of the
Transactions, Sygnet sold substantially all of its owned towers to Dobson Tower
Company, a subsidiary of Dobson, which leased these towers back to Sygnet. See
"Certain Transactions."
 
LEGAL PROCEEDINGS
 
    Sygnet is not currently involved in any pending legal proceedings that
individually or in the aggregate are material to Sygnet. Sygnet is a party to
routine filings and customary regulatory proceedings with the FCC and state
public utility commissions relating to its operations.

(1) Everett R. Dobson was elected Chief Executive Officer of the Company on July
    26, 1998 and he received no compensation from the Company during 1998.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The Company does not have a separate compensation committee of its Board of
Directors. The Board of Directors will set the compensation for its executive
officers and Everett R. Dobson, Chairman of the Board and Chief Executive
Officer, and Stephen T. Dobson, Treasurer and Secretary, are directors and
participate in these deliberations concerning executive officer compensation.
Each of the directors of the Company also serves on the board of directors of
Dobson and on the boards of directors of various subsidiaries of Dobson. As
such, each of the directors will participate in the deliberations concerning
executive officer compensation for Dobson and its subsidiaries.
 
STOCK OPTION PLANS
 
    Key employees of the Company may participate in the Dobson Communications
1996 Stock Option Plan which permits the grant of stock options to purchase
Class B Common Stock of Dobson.
 
                              CERTAIN TRANSACTIONS
 
    The Company has adopted a policy requiring that any material transaction
between the Company and persons or entities affiliated with officers, directors,
or principal stockholders of the Company be on terms no less favorable to the
Company than reasonably could have been obtained in an arm's length transaction
with independent third parties. Any other matters involving potential conflicts
of interests are to be resolved by the Board of Directors on a case-by-case
basis.
 
    Dobson provides certain administrative services, including accounting,
information systems management, human resources management and marketing to the
Company and its subsidiaries. Additionally, officers of the Company are also
officers of Dobson and various of its other subsidiaries. These officers perform
functions for all of the Dobson subsidiaries, including the Company and its
subsidiaries. The Company will reimburse Dobson based on Dobson's cost of
providing the services.
 
    The Company is a party to a tax sharing agreement with Dobson and its other
subsidiaries. The Company, as a member of the affiliated group with Dobson will
join with Dobson and its other subsidiaries in filing a consolidated federal
income tax return. Under the tax sharing agreement, each subsidiary's
contribution toward the group's consolidated federal income tax liability is
determined as if such party were at all times a separate taxpayer not included
in the group. Based on this determination of separate tax liability, each
subsidiary pays to Dobson an amount in lieu of taxes equal to the amount the
subsidiary would be obligated to pay if it filed returns as a separate taxpayer.
If, but only to the extent that, the group realizes a tax benefit for any
taxable year as a result of the inclusion of a subsidiary's tax items in the
determination of tax liability of the group, Dobson will pay to the subsidiary
an amount equal to such tax benefits realized.
 
    As part of the Transactions, Sygnet sold substantially all of the towers
owned by Sygnet to Dobson Tower Company, a wholly owned subsidiary of Dobson,
for $25.0 million. Dobson Tower Company then
 
                                       60
<PAGE>
leased the towers back to Sygnet under an operating lease, with annual lease
payments of approximately $1.6 million.
 
                             PRINCIPAL SHAREHOLDER
 
    All of the issued and outstanding capital stock of the Company is owned
beneficially and of record by Dobson. Everett R. Dobson beneficially owns
capital stock of Dobson representing 84.8% of the voting power of Dobson's
outstanding capital stock.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
NEW BANK FACILITIES
 
    The New Bank Facilities provided by NationsBank, as Agent, include a $50.0
million senior secured, reducing revolving credit facility (the "Revolving
Credit Facility") and a series of three term loans aggregating $380.0 million
("Term Loan Facilities") to be used for permitted acquisitions, restricted
payments, the Sygnet Acquisition, to refinance Sygnet's existing indebtedness
and to fund capital expenditures, permitted investments, working capital and
other corporate purposes.
 
    The following summary of the material provisions of the New Bank Facilities
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, the definitive loan documents. Capitalized terms that
are used but not defined in this section have the meanings that are given such
terms in the definitive loan agreement.
 
    The New Bank Facilities aggregate $430.0 million and include (a) a $50.0
million, 7 3/4 year reducing revolving credit facility, (b) a $125.0 million,
7 3/4 year term loan ("Term Loan A"), (c) a $155.0 million, 8 1/4 year term loan
("Term Loan B") and (d) a $100.0 million, 9 year term loan ("Term Loan C").
 
    Borrowings under the Revolving Credit Facility and Term Loans A and B will
bear interest, payable at least quarterly, at Sygnet's option, at (a) the
"Applicable Margin" plus the greater of (i) the Federal Funds Effective Rate
plus 0.5% and (ii) the prime rate (the "Base Rate"), or (b) the "Applicable
Margin" plus Reserve Adjusted LIBOR ("LIBOR") for interest periods of 1, 2, 3 or
6 months. The "Applicable Margin" for the Revolving Credit Facility and Term
Loan A fluctuates based on Sygnet's leverage and is the Base Rate plus 0.75% to
2.00% or LIBOR plus 1.75% to 3.00%. For Term Loan B, the "Applicable Margin"
fluctuates based on Sygnet's leverage and is the Base Rate plus 1.75% to 2.25%
or LIBOR plus 2.75% to 3.25%. Term Loan C will bear interest at LIBOR plus 3.75%
for interest periods of 1, 2, 3 or 6 months.
 
    Commencing with the quarter ending December 31, 2000, the borrowing
commitment under the Revolving Credit Facility and Term Loan A will reduce
quarterly under the following annual amortization schedule:

</TABLE>
 
    The commitments under the New Bank Facilities will all be permanently
reduced by an amount equal to 100% of the net cash proceeds from sales of assets
in excess of $5.0 million, to the extent not reinvested within 12 months, by an
amount equal to 100% of the net cash proceeds received from certain equity or
debt issuances and by 75% or 50% of excess cash flow, depending on Sygnet's
leverage. In addition, to the extent amounts have been borrowed in respect of
the Tower Sale Leaseback, such amounts shall be repaid with the net proceeds
therefrom and the commitments under each of Term Loan A and Term Loan B will
decrease by $10.0 million.
 
    Sygnet may, without premium or penalty, prepay advances bearing interest
based on the Base Rate at any time and may, without premium or penalty, prepay
advances bearing interest based on the LIBOR rate at the end of an applicable
interest period. Term Loan C may be redeemed in whole or in part at 102% of the
principal amount through December 31, 1999, 101% of the principal amount through
December 31, 2001 and thereafter at 100%.
 
    The New Bank Facilities contain a number of covenants including, among
others, covenants limiting the ability of Sygnet and each of its subsidiaries to
incur debt, make loans, create liens, make guarantees and investments, change
their business, engage in transactions with affiliates, sell assets, enter into
restrictive agreements, engage in sale leaseback transactions or new business
and engage in mergers and acquisitions. The New Bank Facilities will contain
other usual and customary negative and affirmative covenants, including Year
2000 compliance.
 
    The New Bank Facilities restrict Sygnet and Sygnet Communications from
declaring and paying distributions or making restrictive payments. However,
Sygnet will be permitted to pay dividends to pay (i) scheduled interest on the
Notes commencing after the first six interest payments on the Notes and (ii)
regularly scheduled payments on up to $120,000,000 in liquidation preference
value of Dobson's preferred stock, commencing January 15, 2003, in each case
unless if at the time of such dividend or distribution an event of default
(other than an event of default resulting solely from the breach of a
representation or warranty) exists or would be caused by such dividend or
distribution; provided that, with respect to any event of default (other than a
payment default (including by way of acceleration), a bankruptcy event with
respect to the Company, Sygnet or Sygnet Communications or Dobson or any of its
restricted subsidiaries or the loss of a material license or cellular system),
Sygnet and Sygnet Communications will not be prohibited from paying dividends to
the Company to pay scheduled interest on the Notes for more than 180 days.
 
    Sygnet is required to maintain certain financial ratios, including, among
others, a ratio of total debt to cash flow, a ratio of operating cash flow to
pro forma debt service, a ratio of operating cash flow to cash interest expense
and a fixed charge coverage ratio. In addition, Dobson and the Company will be
required to maintain a ratio of debt to operating cash flow.
 
    Failure to satisfy any of the financial covenants will constitute an Event
of Default under the New Bank Facilities, permitting the lenders, after notice,
to terminate the commitment and/or accelerate payment of outstanding
indebtedness notwithstanding the ability of Sygnet to meet its debt service
obligations. The New Bank Facilities include other customary events of default
including, without limitation, loss of franchise or any material license; breach
of representations, warranties and covenants; insolvency or bankruptcy of Sygnet
or any of its subsidiaries or of Dobson or any of its subsidiaries; cross
default to other material indebtedness, leases, contracts of Sygnet, its
subsidiaries, or of Dobson and its subsidiaries (excluding Logix Communications
Enterprises, Inc.); any material adverse change; dissolution or termination of
Sygnet or any of its subsidiaries or of Dobson; if Dobson fails to maintain
direct voting

and economic control of Sygnet and its subsidiaries; and if less than two-thirds
of the existing executive management team of Dobson continue to hold executive
positions with Dobson.
 
    Sygnet's obligations under the New Bank Facilities are guaranteed by its
subsidiaries. Borrowings under the New Bank Facilities will be secured by a
first perfected security interest in all assets of Sygnet and its present and
future subsidiaries including a pledge of all intercompany notes.

redemption relating to such Note shall state the portion of the principal amount
thereof to be redeemed. A new Note in principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note.
 
REGISTRATION RIGHTS
 
    The Company and the Initial Purchasers entered into a Registration Rights
Agreement (the "Registration Rights Agreement") on December 23, 1998. Pursuant
to the Registration Rights Agreement the Company agreed, for the benefit of the
Holders, at its expense, to (1) file a registration statement (the "Exchange
Offer Registration Statement") with the Commission with respect to a registered
offer to exchange the Notes for a new issue of debt securities of the Company
(the "Exchange Notes") to be issued under the Indenture in the same aggregate
principal amount as and with terms that will be identical in all respects to the
Notes (except that the Exchange Notes will not contain transfer restrictions),
(2) use its best efforts to cause the Exchange Offer Registration Statement to
be declared effective under the Securities Act and (3) use its best efforts to
consummate the Exchange Offer. Promptly after the Exchange Offer Registration
Statement is declared effective, the Company will offer the Exchange Notes in
exchange for surrender of the Notes (the "Exchange Offer"). The Company will
keep the Exchange Offer open for not less than 20 business days after the date
notice of the Exchange Offer is mailed to the Holders. For each Note tendered to
the Company pursuant to the Exchange Offer and not validly withdrawn by the
Holder thereof, the Holder of such Note will receive an Exchange Note having a
principal amount equal to the principal amount of such surrendered Note.
 
    Based on existing interpretations of the Securities Act by the staff of the
Commission set forth in several no-action letters to third parties, and subject
to the immediately following sentence, the Company believes that the Exchange
Notes that will be issued pursuant to the Exchange Offer may be offered for
resale, resold and otherwise transferred by the Holders thereof without further
compliance with the registration and prospectus delivery provisions of the
Securities Act. However, any purchaser of Notes who is an "affiliate" of the
Company or who intends to participate in the Exchange Offer for the purpose of
 
                                       66
<PAGE>
distributing the Exchange Notes, (1) will not be able to rely on the
interpretations by the staff of the Commission set forth in the above-mentioned
no-action letters, (2) will not be able to tender its Notes in the Exchange
Offer and (3) must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any sale or transfer of
the Notes unless such sale or transfer is made pursuant to an exemption from
such requirements.
 
    Each Holder who wishes to exchange Notes for Exchange Notes in the Exchange
Offer is required to represent that (1) it is not an affiliate of the Company,
(2) any Exchange Notes to be received by it were acquired in the ordinary course
of its business and (3) at the time of commencement of the Exchange Offer, it
has no arrangement with any person to participate in the distribution (within
the meaning of the Securities Act) of the Exchange Notes. In addition, in
connection with any resales of Exchange Notes, any broker-dealer (an "Exchanging
Dealer") who acquired the Notes for its own account as a result of market-making
activities or other trading activities must deliver a prospectus meeting the
requirements of the Securities Act. The Commission has taken the position that
Exchanging Dealers may fulfill their prospectus delivery requirements with
respect to the Exchange Notes (other than a resale of an unsold allotment form
the original sale of the Notes) with the prospectus contained in the Exchange
Offer Registration Statement. Under the Registration Rights Agreement, the
Company is required to allow Exchanging Dealers to use the prospectus contained
in the Exchange Offer Registration Statement in connection with the resale of
such Exchange Notes.
 
    If any changes in law or applicable interpretations of the staff of the
Commission do not permit the Company to effect the Exchange Offer, or if for any
reason the Exchange Offer is not consummated within 180 days of the Closing Date
or in certain other circumstances, the Company will, at its expense (1) file
with the Commission a shelf registration statement (the "Shelf Registration
Statement") covering resales of the Notes, (2) use its best efforts to cause the
Shelf Registration Statement to be declared effective under the Securities Act
and (3) keep effective the Shelf Registration Statement until two years after
the Closing Date (or such shorter period of time that will terminate when all
the Notes covered thereby have been sold pursuant thereto or in certain other
circumstances). The Company will, in the event of the filing of a Shelf
Registration Statement, provide to each Holder covered by the Shelf Registration
Statement copies of the prospectus that is a part of the Shelf Registration
Statement, notify each Holder when the Shelf Registration Statement has become
effective and take certain other actions as are required to permit unrestricted
resales of the Notes. A Holder that sells such Notes pursuant to the Shelf
Registration Statement generally will be required to be named as a selling
securityholder in the related prospectus and to deliver a prospectus to the
purchaser, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the Registration Rights Agreement that are applicable to such
Holder (including certain indemnification obligations). In addition, each Holder
will be required to deliver certain information to be used in connection with
the Shelf Registration Statement in order to have its Notes included in the
Shelf Registration Statement.
 
    If either (a) the Exchange Offer is not consummated on or prior to June 21,
1999 or (b) a Shelf Registration Statement is not declared effective when
required, the Company will pay liquidated damages ("Liquidated Damages") to each
Holder of Notes in an amount equal to .5% per annum of the principal amount
thereof, payable on June 15 and December 15. Upon the consummation of the
Exchange Offer or the effectiveness of the Shelf Registration Statement, as the
case may be, Liquidated Damages will cease to accrue.
 
    The summary herein of certain provisions of the Registration Rights
Agreement does not purport to be complete and is qualified in its entirety by
reference to the Registration Rights Agreement.
 
PLEDGED SECURITIES
 
    Pursuant to the Indenture, on the Closing Date the Company purchased and
pledged to the Trustee for the benefit of the Holders of the Notes the Pledged
Securities in such amount as will be sufficient upon
 
                                       67
<PAGE>
receipt of scheduled interest and principal payments of such securities to
provide for payment in full of the first six scheduled interest payments due on
the Notes. The Company used approximately $67.7 million of the net proceeds of
the Offering to acquire the Pledged Securities. The Pledged Securities have been
pledged by the Company to the Trustee for the benefit of the Holders of the
Notes pursuant to the Pledge Agreement and will be held by the Trustee in the
Pledge Account. Pursuant to the Pledge Agreement, immediately prior to an
Interest Payment Date on the Notes, the Company may either deposit with the
Trustee from funds otherwise available to the Company cash sufficient to pay the
interest scheduled to be paid on such date or the Company may direct the Trustee
to release from the Pledge Account proceeds sufficient to pay interest then due
on the Notes. In the event that the Company exercises the former option, the
Company may thereafter direct the Trustee to release to the Company proceeds or
Pledged Securities from the Pledge Account in like amount. A failure by the
Company to pay interest on the Notes in a timely manner through the first six
scheduled interest payment dates will constitute an immediate Event of Default
under the Indenture, with no grace or cure period.
 
    The Notes are secured in part by a first priority security interest in the
Pledged Securities and in the Pledge Account and, accordingly, the Pledged
Securities and the Pledge Account will also secure repayment of the principal
amount of the Notes to the extent of such security. Under the Pledge Agreement,
once the Company makes the first six scheduled interest payments on the Notes,
all of the remaining Pledged Securities and any other amounts in the Pledge
Account, if any, will be released from the Pledge Account and thereafter the
Notes will be unsecured.
 
RANKING
 
    The Notes are unsubordinated Indebtedness of the Company and rank equally in
right of payment with all other unsubordinated indebtedness of the Company and
senior in right of payment to all subordinated indebtedness of the Company.
After giving PRO FORMA effect to the Transactions, as of September 30, 1998, the
Company would have had on an unconsolidated basis no indebtedness other than the
Notes. The Company is a holding company and the Notes will be effectively
subordinated to all existing and future liabilities (including trade payables)
of the Company's subsidiaries. As of September 30, 1998, on the same pro forma
basis, the subsidiaries of the Company would have had $605.7 million of
liabilities including $398.2 million of indebtedness, all of which would have
been effectively senior to the Notes. See "Capitalization."

Disqualified Stock if the "asset sale" or "change of control" provisions
applicable to such Capital Stock are no more favorable to the holders of such

case may be, intends to use for substantially the same purpose or purposes as
the assets or properties sold or transferred.
 
    The foregoing restriction does not apply to any sale-leaseback transaction
if (i) the lease is for a period, including renewal rights, of not in excess of
three years; (ii) the lease secures or relates to industrial revenue or
pollution control bonds; (iii) the transaction is solely between the Company and
any Wholly Owned Restricted Subsidiary or solely between Wholly Owned Restricted
Subsidiaries; (iv) the Tower Sale and the Tower Lease; or (v) the Company or
such Restricted Subsidiary, within twelve months after the sale or transfer of
any assets or properties is completed, applies an amount not less than the net
proceeds received from such sale in accordance with clause (A) or (B) of the
first paragraph of the "Limitation on Asset Sales" covenant described below.
 
    LIMITATION ON TRANSACTIONS WITH STOCKHOLDERS AND AFFILIATES
 
    The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into, renew or extend any transaction (including,
without limitation, the purchase, sale, lease or exchange of property or assets,
or the rendering of any service) with any holder (or any Affiliate of such
holder) of 5% or more of any class of Capital Stock of the Company or with any
Affiliate of the Company or any Restricted Subsidiary, except upon fair and
reasonable terms no less favorable to the Company or such Restricted Subsidiary
than could be obtained, at the time of such transaction or, if such transaction
is pursuant to a written agreement, at the time of the execution of the
agreement providing therefor, in a comparable arm's-length transaction with a
Person that is not such a holder or an Affiliate.
 
    The foregoing limitation does not limit, and shall not apply to:
 
        (i) transactions (A) approved by a majority of the members of the Board
    of Directors who do not have any material direct or indirect financial
    interest in or with respect to such transactions or (B) for which the
    Company or a Restricted Subsidiary delivers to the Trustee a written opinion
    of a nationally recognized investment banking firm stating that the
    transaction is fair to the Company or such Restricted Subsidiary from a
    financial point of view;
 
        (ii) any transaction solely between the Company and any of its Wholly
    Owned Restricted Subsidiaries or solely between Wholly Owned Restricted
    Subsidiaries;
 
       (iii) the payment of reasonable and customary regular fees to directors
    of the Company who are not employees of the Company;
 
        (iv) any payments or other transactions pursuant to any tax-sharing
    agreement between the Company and any other Person with which the Company
    files a consolidated tax return or with which the Company is part of a
    consolidated group for tax purposes;
 
        (v) the Tower Sale and the Tower Lease; provided that the Company and
    its Restricted Subsidiaries receive at least $25 million from the Tower Sale
    and the annual rental expense under the Tower Lease is no more than $1.6
    million;
 
        (vi) transactions between the Company or any of its Restricted
    Subsidiaries and Dobson Communications or its Affiliates on terms of the
    kind customarily employed to allocate charges among members of a
    consolidated group of entities, in any such case that are fair and
    reasonable to the Company or such Restricted Subsidiary; PROVIDED that the
    aggregate consideration subject to such transactions does not exceed $3
    million in any calendar year; or
 
                                       88
<PAGE>
       (vii) any Restricted Payments not prohibited by the "Limitation on
    Restricted Payments" covenant.
 
    Notwithstanding the foregoing, any transaction covered by the first
paragraph of this "Limitation on Transactions with Stockholders and Affiliates"
covenant and not covered by clauses (ii) through (vii) of this paragraph, the
aggregate amount of which (x) exceeds $1.0 million in value, must be approved or
determined to be fair in the manner provided for in clause (i)(A) or (B) above
or (y) exceeds $5.0 million in value, must be approved or determined to be fair
in the manner provided for in clause (i)(B) above.
 
    LIMITATION ON ASSET SALES
 
    The Company will not, and will not permit any Restricted Subsidiary to,
consummate any Asset Sale, unless (i) the consideration received by the Company
or such Restricted Subsidiary is at least equal to the fair market value of the
assets sold or disposed of and (ii) at least 85% of the consideration received
consists of cash or Temporary Cash Investments.
 
    In the event and to the extent that the Net Cash Proceeds received by the
Company or any of its Restricted Subsidiaries from one or more Asset Sales
occurring on or after the Closing Date in any period of 12 consecutive months
exceed 10% of Adjusted Consolidated Net Tangible Assets (determined as of the
date closest to the commencement of such 12-month period for which a
consolidated balance sheet of the Company and its subsidiaries has been filed
with the Commission), then the Company shall or shall cause the relevant
Restricted Subsidiary to:
 
        (i) within 12 months after the date Net Cash Proceeds so received exceed
    10% of Adjusted Consolidated Net Tangible Assets
 
           (A) apply an amount equal to such excess Net Cash Proceeds to
       permanently repay Senior Indebtedness of the Company or any Restricted
       Subsidiary providing a Subsidiary Guarantee pursuant to the "Limitation
       on Issuances of Guarantees by Restricted Subsidiaries" covenant described
       above or Indebtedness of any other Restricted Subsidiary, in each case
       owing to a Person other than the Company or any of its Restricted
       Subsidiaries or
 
            (B) invest an equal amount, or the amount not so applied pursuant to
       clause (A) (or enter into a definitive agreement committing to so invest
       within 12 months after the date of such agreement), in property or assets
       (other than current assets) of a nature or type or that are used in a
       business (or in a company having property and assets of a nature or type,
       or engaged in a business) similar or related to the nature or type of the
       property and assets of, or the business of, the Company and its
       Restricted Subsidiaries existing on the date of such investment and
 
        (ii) apply (no later than the end of the 12-month period referred to in
    clause (i)) such excess Net Cash Proceeds (to the extent not applied
    pursuant to clause (i)) as provided in the following paragraph of this
    "Limitation on Asset Sales" covenant. The amount of such excess Net Cash
    Proceeds required to be applied (or to be committed to be applied) during
    such twelve-month period as set forth in clause (i) of the preceding
    sentence and not applied as so required by the end of such period shall
    constitute "Excess Proceeds."
 
    If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
"Limitation on Asset Sales" covenant totals at least $5 million, the Company
must commence, not later than the fifteenth Business Day of such month, and
consummate an Offer to Purchase from the Holders on a pro rata basis an
aggregate principal amount of Notes equal to the Excess Proceeds on such date,
at a purchase price equal to 100% of the principal amount thereof, plus, in each
case, accrued interest (if any) to the Payment Date.
 
                                       89
<PAGE>
REPURCHASE OF NOTES UPON A CHANGE OF CONTROL
 
    The Company must commence, within 30 days of the occurrence of a Change of
Control, and consummate an Offer to Purchase for all Notes then outstanding, at
a purchase price equal to 101% of the principal amount thereof, plus accrued
interest (if any) to the Payment Date.
 
    There can be no assurance that the Company will have sufficient funds
available at the time of any Change of Control to make any debt payment
(including repurchases of Notes) required by the foregoing covenant (as well as
may be contained in other securities of the Company which might be outstanding
at the time). The above covenant requiring the Company to repurchase the Notes
will, unless consents are obtained, require the Company to repay all
indebtedness then outstanding which by its terms would prohibit such Note
repurchase, either prior to or concurrently with such Note repurchase.
 
COMMISSION REPORTS AND REPORTS TO HOLDERS
 
    At all times from and after the earlier of (i) the date of the commencement
of an Exchange Offer or the effectiveness of the Shelf Registration Statement
(the "Registration") and (ii) June 21, 1999, in either case, whether or not the
Company is then required to file reports with the Commission, the Company shall
file with the Commission all such reports and other information as it would be
required to file with the Commission by Sections 13(a) or 15(d) under the
Securities Exchange Act of 1934 if it were subject thereto. The Company shall
supply the Trustee and each Holder or shall supply to the Trustee for forwarding
to each such Holder, without cost to such Holder, copies of such reports and
other information. In addition, at all times prior to the earlier of the date of
the Registration and June 21, 1999, the Company shall, at its cost, deliver to
each Holder of the Notes quarterly and annual reports substantially equivalent
to those which would be required by the Exchange Act. In addition, at all times
prior to the Registration, upon the request of any Holder or any prospective
purchaser of the Notes designated by a Holder, the Company shall supply to such
Holder or such prospective purchaser the information required under Rule 144A
under the Securities Act.
 
EVENTS OF DEFAULT
 
    The following events are defined as "Events of Default" in the Indenture:
 
        (a) default in the payment of principal of (or premium, if any, on) any
    Note when the same becomes due and payable at maturity, upon acceleration,
    redemption or otherwise;
 
        (b) default in the payment of interest on any Note when the same becomes
    due and payable, and such default continues for a period of 30 days;
    PROVIDED that a failure to make any of the first six scheduled interest
    payments on the Notes in a timely manner will constitute an Event of Default
    with no grace or cure period;
 
        (c) default in the performance or breach of the provisions of the
    Indenture applicable to mergers, consolidations and transfers of all or
    substantially all of the assets of the Company or the failure to make or
    consummate an Offer to Purchase in accordance with the "Limitation on Asset
    Sales" or "Repurchase of Notes upon a Change of Control" covenant;
 
        (d) the Company defaults in the performance of or breaches any other
    covenant or agreement of the Company in the Indenture or under the Notes
    (other than a default specified in clause (a), (b) or (c) above) and such
    default or breach continues for a period of 30 consecutive days after
    written notice by the Trustee or the Holders of 25% or more in aggregate
    principal amount of the Notes;
 
        (e) there occurs with respect to any issue or issues of Indebtedness of
    the Company or any Significant Subsidiary having an outstanding principal
    amount of $5 million or more in the aggregate for all such issues of all
    such Persons, whether such Indebtedness now exists or shall hereafter be
    created, (I) an event of default that has caused the holder thereof to
    declare such Indebtedness to be
 
                                       90
<PAGE>
    due and payable prior to its Stated Maturity and such Indebtedness has not
    been discharged in full or such acceleration has not been rescinded or
    annulled within 30 days of such acceleration and/or (II) the failure to make
    a principal payment at the final (but not any interim) fixed maturity and
    such defaulted payment shall not have been made, waived or extended within
    30 days of such payment default;
 
        (f) any final judgment or order (not covered by insurance) for the
    payment of money in excess of $5 million in the aggregate for all such final
    judgments or orders against all such Persons (treating any deductibles,
    self-insurance or retention as not so covered) shall be rendered against the
    Company or any Significant Subsidiary and shall not be paid or discharged,
    and there shall be any period of 30 consecutive days following entry of the
    final judgment or order that causes the aggregate amount for all such final
    judgments or orders outstanding and not paid or discharged against all such
    Persons to exceed $5 million during which a stay of enforcement of such
    final judgment or order, by reason of a pending appeal or otherwise, shall
    not be in effect;
 
        (g) a court having jurisdiction in the premises enters a decree or order
    for (A) relief in respect of the Company or any Significant Subsidiary in an
    involuntary case under any applicable bankruptcy, insolvency or other
    similar law now or hereafter in effect, (B) appointment of a receiver,
    liquidator, assignee, custodian, trustee, sequestrator or similar official
    of the Company or any Significant Subsidiary or for all or substantially all
    of the property and assets of the Company or any Significant Subsidiary or
    (C) the winding up or liquidation of the affairs of the Company or any
    Significant Subsidiary and, in each case, such decree or order shall remain
    unstayed and in effect for a period of 30 consecutive days;
 
        (h) the Company or any Significant Subsidiary (A) commences a voluntary
    case under any applicable bankruptcy, insolvency or other similar law now or
    hereafter in effect, or consents to the entry of an order for relief in an
    involuntary case under any such law, (B) consents to the appointment of or
    taking possession by a receiver, liquidator, assignee, custodian, trustee,
    sequestrator or similar official of the Company or any Significant
    Subsidiary or for all or substantially all of the property and assets of the
    Company or any Significant Subsidiary or (C) effects any general assignment
    for the benefit of creditors; or
 
        (i) the Pledge Agreement shall cease to be in full force and effect or
    enforceable in accordance with its terms, other than in accordance with its
    terms.
 
    If an Event of Default (other than an Event of Default specified in clause
(g) or (h) above that occurs with respect to the Company) occurs and is
continuing under the Indenture, the Trustee or the Holders of at least 25% in
aggregate principal amount of the Notes, then outstanding, by written notice to
the Company (and to the Trustee if such notice is given by the Holders), may,
and the Trustee at the request of such Holders shall, declare the principal of,
premium, if any, and accrued interest on the Notes to be immediately due and
payable. Upon a declaration of acceleration, such principal of, premium, if any,
and accrued interest shall be immediately due and payable. In the event of a
declaration of acceleration because an Event of Default set forth in clause (e)
above has occurred and is continuing, such declaration of acceleration shall be
automatically rescinded and annulled if the event of default triggering such
Event of Default pursuant to clause (e) shall be remedied or cured by the
Company or the relevant Significant Subsidiary or waived by the holders of the
relevant Indebtedness within 60 days after the declaration of acceleration with
respect thereto. If an Event of Default specified in clause (g) or (h) above
occurs with respect to the Company, the principal of, premium, if any, and
accrued interest on the Notes then outstanding shall IPSO FACTO become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder. At any time after declaration of acceleration, but
before a judgment or decree for the payment of the money due has been obtained
by the Trustee, the Holders of at least a majority in principal amount of the
outstanding Notes by written notice to the Company and to the
 
                                       91
<PAGE>
Trustee, may waive all past defaults and rescind and annul a declaration of
acceleration and its consequences if (i) all existing Events of Default, other
than the nonpayment of the principal of, premium, if any, and interest on the
Notes that have become due solely by such declaration of acceleration, have been
cured or waived and (ii) the rescission would not conflict with any judgment or
decree of a court of competent jurisdiction. For information as to the waiver of
defaults, see "--Modification and Waiver."
 
    The Holders of at least a majority in aggregate principal amount of the
outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the Trustee
in personal liability, or that the Trustee determines in good faith may be
unduly prejudicial to the rights of Holders of Notes not joining in the giving
of such direction and may take any other action it deems proper that is not
inconsistent with any such direction received from Holders of Notes. A Holder
may not pursue any remedy with respect to the Indenture or the Notes unless: (i)
the Holder gives the Trustee written notice of a continuing Event of Default;
(ii) the Holders of at least 25% in aggregate principal amount of outstanding
Notes make a written request to the Trustee to pursue the remedy; (iii) such
Holder or Holders offer the Trustee indemnity satisfactory to the Trustee
against any costs, liability or expense; (iv) the Trustee does not comply with
the request within 60 days after receipt of the request and the offer of
indemnity; and (v) during such 60-day period, the Holders of a majority in
aggregate principal amount of the outstanding Notes do not give the Trustee a
direction that is inconsistent with the request. However, such limitations do
not apply to the right of any Holder of a Note to receive payment of the
principal of, premium, if any, or interest on, such Note or to bring suit for
the enforcement of any such payment, on or after the due date expressed in the
Notes, which right shall not be impaired or affected without the consent of the
Holder.
 
    The Indenture will require certain officers of the Company to certify, on or
before a date not more than 90 days after the end of each fiscal year, that a
review has been conducted of the activities of the Company and its Restricted
Subsidiaries and the Company's and its Restricted Subsidiaries' performance
under the Indenture and that the Company has fulfilled all obligations
thereunder, or, if there has been a default in the fulfillment of any such
obligation, specifying each such default and the nature and status thereof. The
Company will also be obligated to notify the Trustee of any default or defaults
in the performance of any covenants or agreements under the Indenture.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
    The Company will not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its property
and assets (as an entirety or substantially an entirety in one transaction or a
series of related transactions) to, any Person or permit any Person to merge
with or into the Company unless:
 
        (i) the Company shall be the continuing Person, or the Person (if other
    than the Company) formed by such consolidation or into which the Company is
    merged or that acquired or leased such property and assets of the Company
    shall be a corporation organized and validly existing under the laws of the
    United States of America or any jurisdiction thereof and shall expressly
    assume, by a supplemental indenture, executed and delivered to the Trustee,
    all of the obligations of the Company on all of the Notes and under the
    Indenture;
 
        (ii) immediately after giving effect to such transaction, no Default or
    Event of Default shall have occurred and be continuing;
 
       (iii) immediately after giving effect to such transaction on a pro forma
    basis, the Company or any Person becoming the successor obligor of the Notes
    shall have a Consolidated Net Worth equal to or greater than the
    Consolidated Net Worth of the Company immediately prior to such transaction;
 
                                       92
<PAGE>
        (iv) immediately after giving effect to such transaction on a pro forma
    basis the Company, or any Person becoming the successor obligor of the
    Notes, as the case may be, could Incur at least $1.00 of Indebtedness under
    the first paragraph of the "Limitation on Indebtedness" covenant; PROVIDED
    that this clause (iv) shall not apply to a consolidation or merger with or
    into a Wholly Owned Restricted Subsidiary with a positive net worth;
    PROVIDED that, in connection with any such merger or consolidation, no
    consideration (other than Common Stock in the surviving Person or the
    Company) shall be issued or distributed to the stockholders of the Company;
    and
 
        (v) the Company delivers to the Trustee an Officers' Certificate
    (attaching the arithmetic computations to demonstrate compliance with
    clauses (iii) and (iv)) and Opinion of Counsel, in each case stating that
    such consolidation, merger or transfer and such supplemental indenture
    complies with this provision and that all conditions precedent provided for
    herein relating to such transaction have been complied with;
 
PROVIDED, HOWEVER, that clauses (iii) and (iv) above shall not apply if, in the
good faith determination of the Board of Directors of the Company, whose
determination shall be evidenced by a Board Resolution, the principal purpose of
such transaction is to change the state of incorporation of the Company;
PROVIDED that any such transaction shall not have as one of its purposes the
evasion of the foregoing limitations.
 
DEFEASANCE
 
    DEFEASANCE AND DISCHARGE.  The Indenture provides that the Company will be
deemed to have paid and will be discharged from any and all obligations in
respect of the Notes on the 123rd day after the deposit referred to below, and
the provisions of the Indenture will no longer be in effect with respect to the
Notes (except for, among other matters, certain obligations to register the
transfer or exchange of the Notes, to replace stolen, lost or mutilated Notes,
to maintain paying agencies and to hold monies for payment in trust) if, among
other things, (A) the Company has deposited with the Trustee, in trust, money
and/or U.S. Government Obligations that through the payment of interest and
principal in respect thereof in accordance with their terms will provide money
in an amount sufficient to pay the principal of, premium, if any, and accrued
interest on the Notes on the Stated Maturity of such payments in accordance with
the terms of the Indenture and the Notes, (B) the Company has delivered to the
Trustee (i) either (x) an Opinion of Counsel to the effect that Holders will not
recognize income, gain or loss for federal income tax purposes as a result of
the Company's exercise of its option under this "Defeasance" provision and will
be subject to federal income tax on the same amount and in the same manner and
at the same times as would have been the case if such deposit, defeasance and
discharge had not occurred, which Opinion of Counsel must be based upon (and
accompanied by a copy of) a ruling of the Internal Revenue Service to the same
effect unless there has been a change in applicable federal income tax law after
the Closing Date such that a ruling is no longer required or (y) a ruling
directed to the Trustee received from the Internal Revenue Service to the same
effect as the aforementioned Opinion of Counsel and (ii) an Opinion of Counsel
to the effect that the creation of the defeasance trust does not violate the
Investment Company Act of 1940 and after the passage of 123 days following the
deposit (except with respect to any trust funds for the account of any Holder
who may be deemed an "insider" for purposes of the United States Bankruptcy
Code, after one year following the deposit); the trust funds will not be subject
to the effect of Section 547 of the United States Bankruptcy Code or Section 15
of the New York Debtor and Creditor Law, (C) immediately after giving effect to
such deposit on a pro forma basis, no Default or Event of Default shall have
occurred and be continuing on the date of such deposit or during the period
ending on the 123rd day after the date of such deposit, and such deposit shall
not result in a breach or violation of, or constitute a default under, any other
agreement or instrument to which the Company or any of its Subsidiaries is a
party or by which the Company or any of its Subsidiaries is bound and (D) if at
such time the Notes are listed on a national securities exchange, the Company
has delivered to the Trustee an Opinion of Counsel to the effect that the Notes
will not be delisted as a result of such deposit, defeasance and discharge.
 
                                       93
<PAGE>
    DEFEASANCE OF CERTAIN COVENANTS AND CERTAIN EVENTS OF DEFAULT.  The
Indenture further provides that the provisions of the Indenture will no longer
be in effect with respect to clauses (iii) and (iv) under "Consolidation, Merger
and Sale of Assets" and all the covenants described herein under "Covenants,"
clauses (c) and (d) under "Events of Default" with respect to such clauses (iii)
and (iv) under "Consolidation, Merger and Sale of Assets" and such covenants and
clauses (e) and (f) under "Events of Default" shall be deemed not to be Events
of Default, upon, among other things, the deposit with the Trustee, in trust, of
money and/or U.S. Government Obligations that through the payment of interest
and principal in respect thereof in accordance with their terms will provide
money in an amount sufficient to pay the principal of, premium, if any, and
accrued interest on the Notes on the Stated Maturity of such payments in
accordance with the terms of the Indenture and the Notes, the satisfaction of
the provisions described in clauses (B)(ii), (C) and (D) of the preceding
paragraph and the delivery by the Company to the Trustee of an Opinion of
Counsel to the effect that, among other things, the Holders will not recognize
income, gain or loss for federal income tax purposes as a result of such deposit
and defeasance of certain covenants and Events of Default and will be subject to
federal income tax on the same amount and in the same manner and at the same
times as would have been the case if such deposit and defeasance had not
occurred.
 
    DEFEASANCE AND CERTAIN OTHER EVENTS OF DEFAULT.  In the event the Company
exercises its option to omit compliance with certain covenants and provisions of
the Indenture with respect to the Notes as described in the immediately
preceding paragraphs and the Notes are declared due and payable because of the
occurrence of an Event of Default that remains applicable, the amount of money
and/or U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on the Notes at the time of their Stated Maturity
but may not be sufficient to pay amounts due on the Notes at the time of the
acceleration resulting from such Event of Default. However, the Company will
remain liable for such payments.
 
MODIFICATION AND WAIVER
 
    Modifications and amendments of the Indenture may be made by the Company and
the Trustee with the consent of the Holders of not less than a majority in
aggregate principal amount of the outstanding Notes; PROVIDED, HOWEVER, that no
such modification or amendment may, without the consent of each Holder affected
thereby, (i) change the Stated Maturity of the principal of, or any installment
of interest on, any Note, (ii) reduce the principal of, or premium, if any, or
interest on, any Note, (iii) change the place or currency of payment of
principal of, or premium, if any, or interest on, any Note, (iv) impair the
right to institute suit for the enforcement of any payment on or after the
Stated Maturity (or, in the case of a redemption, on or after the Redemption
Date) of any Note, (v) reduce the above-stated percentage of outstanding Notes
the consent of whose Holders is necessary to modify or amend the Indenture, (vi)
waive a default in the payment of principal of, premium, if any, or interest on
the Notes or (vii) reduce the percentage or aggregate principal amount of
outstanding Notes the consent of whose Holders is necessary for waiver of
compliance with certain provisions of the Indenture or for waiver of certain
defaults.
 
NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS OR
  EMPLOYEES
 
    The Indenture provides that no recourse for the payment of the principal of,
premium, if any, or interest on any of the Notes or for any claim based thereon
or otherwise in respect thereof, and no recourse under or upon any obligation,
covenant or agreement of the Company in the Escrow and Security Agreement, the
Indenture, or in any of the Notes or because of the creation of any Indebtedness
represented thereby, shall be had against any incorporator, stockholder,
officer, director, employee or controlling person of the Company or of any
successor Person thereof. Each Holder, by accepting the Notes, waives and
releases all such liability.
 
                                       94
<PAGE>
CONCERNING THE TRUSTEE
 
    The Indenture provides that, except during the continuance of a Default, the
Trustee will not be liable, except for the performance of such duties as are
specifically set forth in such Indenture. If an Event of Default has occurred
and is continuing, the Trustee will use the same degree of care and skill in its
exercise of the rights and powers vested in it under the Indenture as a prudent
person would exercise under the circumstances in the conduct of such person's
own affairs.
 
    The Indenture and provisions of the Trust Indenture Act of 1939, as amended,
incorporated by reference therein contain limitations on the rights of the
Trustee, should it become a creditor of the Company, to obtain payment of claims
in certain cases or to realize on certain property received by it in respect of
any such claims, as security or otherwise. The Trustee is permitted to engage in
other transactions; PROVIDED, HOWEVER, that if it acquires any conflicting
interest, it must eliminate such conflict or resign.
 
BOOK-ENTRY, DELIVERY AND FORM
 
    Except as set forth herein, the Notes have initially been issued in the form
of one or more global notes. The global notes will be deposited on the Closing
Date with, or on behalf of, The Depository Trust Company (the "Depositary") and
registered in the name of Cede & Co., as nominee of the Depositary (such nominee
being referred to herein as the "Global Note Holder").
 
    Notes offered and sold in reliance on Regulation S will initially be
represented by one or more permanent global notes in definitive, fully
registered form (the "Offshore Global Note") which will be registered in the
name of the Global Note Holder and deposited on behalf of the purchasers of the
Notes represented thereby with a custodian for the Global Note Holder for credit
to the respective accounts of the purchasers (or to such other accounts as they
may direct) at the Euroclear System ("Euroclear") or Cedel Bank, societe anonyme
("Cedel Bank"). Prior to the 40th day after the later of the commencement of
this offering and the Closing Date, interests in the Offshore Global Note may
only be held through Euroclear or Cedel Bank.
 
    Notes offered and sold to "Qualified Institutional Buyers" in reliance on
Rule 144A under the Securities Act will be represented by one or more permanent
global notes in definitive, fully registered form (the "U.S. Global Note" and
together with the Offshore Global Note, the "Global Notes") which will be
registered in the name of the Global Note Holder and deposited on behalf of the
purchasers of the Notes represented thereby with a custodian for the Global Note
Holder for credit to the respective accounts of the purchasers (or to such other
accounts as they may direct) at the Depositary.
 
    Notes (1) transferred to institutional "accredited investors" who are not
"Qualified Institutional Buyers" (as such terms are defined under "Notice to
Investors" elsewhere herein ("Non-Global Purchasers")) or (2) issued as
described under "Certificated Notes" below, will be issued in registered,
definitive, certificated form (the "Certificated Notes"). Upon the transfer of
Certificated Notes to a Qualified Institutional Buyer or in an offshore
transaction under Regulation S, such Certificated Notes may, unless the Global
Note shall have previously been exchanged in whole for Certificated Notes, be
exchanged for an interest in a Global Note representing the principal amount of
the Notes being transferred upon delivery of appropriate certificates to the
Trustee.
 
    The Depositary is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the
"Participants") and to facilitate the clearance and settlement of transactions
in such securities between Participants through electronic book-entry changes in
accounts of its Participants. The Participants include securities brokers and
dealers (including the Initial Purchasers), banks and trust companies, clearing
corporations and certain other organizations. Access to the Depositary's system
is also available to other entities such as banks, brokers, dealers and trust
companies (collectively, the "Indirect Participants") that clear through or
maintain a custodial relationship with a
 
                                       95
<PAGE>
Participant, either directly or indirectly. Persons who are not Participants may
beneficially own securities held by or on behalf of the Depositary only through
Participants or Indirect Participants.
 
    The Company expects that pursuant to procedures established by the
Depositary (1) upon deposit of the Global Notes, the Depositary will credit the
accounts of Participants designated by the Initial Purchasers with portions of
the principal amount of the Global Notes and (2) ownership of the Notes
evidenced by the Global Notes will be shown on, and the transfer of ownership
thereof will be effected only through, records maintained by the Depositary
(with respect to the interests of the Participants), the Participants and the
Indirect Participants. Prospective purchasers are advised that the laws of some
states require that certain persons take physical delivery in definitive form of
securities that they own. Consequently, the ability to own, transfer or pledge
Notes evidenced by the Global Notes will be limited to such extent. For certain
other restrictions on the transferability of the Notes, see "Notice to
Investors."
 
    Investors may hold their interests in the Offshore Global Note directly
through Euroclear or Cedel Bank, if they are participants in such systems, or
indirectly through organizations that are participants in such systems.
Beginning 40 days after the later of the commencement of this offering and the
Closing Date (but not earlier), investors may also hold such interests through
organizations other than Euroclear or Cedel Bank that are Participants in the
Depositary. Euroclear and Cedel Bank will hold such interests in the Offshore
Global Note on behalf of their participants through customers' securities
accounts in their respective names on the books of their respective
depositaries, which in turn will hold such interests in the Offshore Global Note
in customers' securities acocunts in the depositaries' names on the books of the
Depositary.
 
    So long as the Global Note Holder is the registered owner of any Notes, the
Global Note Holder will be considered the sole Holder under the Indenture of any
Notes evidenced by the Global Note. Beneficial owners of Notes evidenced by the
Global Notes will not be considered the owners or Holders thereof under the
Indenture for any purpose, including with respect to the giving of any
directions, instructions or approvals to the Trustee thereunder. Neither the
Company nor the Trustee will have any responsibility or liability for any aspect
of the records of the Depositary relating to the Notes.
 
    Payments in respect of the principal of, premium, if any, and interest on
any Notes registered in the name of the Global Note Holder on the applicable
record date will be payable by the Trustee to or at the direction of the Global
Note Holder in its capacity as the registered Holder under the Indenture. Under
the terms of the Indenture, the Company and the Trustee may treat the persons in
whose names Notes, including the Global Notes, are registered as the owners
thereof for the purpose of receiving such payments. Consequently, neither the
Company nor the Trustee has or will have any responsibility or liability for the
payment of such amounts to beneficial owners of Notes. The Company believes,
however, that it is currently the policy of the Depositary to immediately credit
the accounts of the relevant Participants with such payments, in amounts
proportionate to their respective holdings of beneficial interests in the
relevant security as shown on the records of the Depositary. Payments by the
Participants and Indirect Participants to the beneficial owners of Notes will be
governed by standing instructions and customary practice and will be the
responsibility of the Participants and Indirect Participants.
 
    Transfers between Participants will be effected in accordance with the
Depositary's rules and will be settled in immediately available funds. If a
holder requires physical delivery of a Certificated Note for any reason,
including to sell Notes to persons in states which require physical delivery of
such securities or to pledge such securities, such holder must transfer its
interest in the Global Notes in accordance with the normal procedures of the
Depositary and in accordance with the procedures set forth in the Indenture.
 
    Before February 2, 1999, transfers by an owner of a beneficial interest in
the Offshore Global Note to a transferee who takes delivery of such interest
through the U.S. Global Note will be made only in accordance with the applicable
procedures and upon receipt by the Trustee of a written certification from the
transferor of the beneficial interest in the form provided in the Indenture to
the effect that such
 
                                       96
<PAGE>
transfer is being made to a person whom the transferor reasonably believes is a
Qualified Institutional Buyer within the meaning of Rule 144A in a transaction
meeting the requirements of Rule 144A.
 
    Transfers by an owner of a beneficial interest in the U.S. Global Note to a
transferee who takes delivery of such interest through the Offshore Global Note,
whether before, on or after the 40th day after the later of the commencement of
this offering and the Closing Date, will be made only upon receipt by the
Trustee of a certification to the effect that such transfer is being made in
accordance with Regulation S. Transfers of Certificated Notes to persons who
will hold through the U.S. Global Note or the Offshore Global Note will be
subject to certifications provided by the Trustee.
 
    CERTIFICATED NOTES
 
    Transferees of Notes who are not "Qualified Institutional Buyers" as defined
in Rule 144A under the Securities Act may hold Notes only in the form of
Certificated Notes. All such Certificated Notes would be subject to the legend
requirements described herein under "Notice to Investors." In addition, if (1)
the Company notifies the Trustee in writing that the Depositary is no longer
willing or able to act as a depositary and the Company is unable to locate a
qualified successor within 90 days or (2) the Company, at its option, notifies
the Trustee in writing that it elects to cause the issuance of Notes in the form
of Certificated Notes under the Indenture then, upon surrender by the Global
Note Holder of the Global Notes, Certificated Notes will be issued to each
person that the Global Note Holder and the Depositary identify as being the
beneficial owner of the related Notes.
 
    Neither the Company nor the Trustee will be liable for any delay by the
Global Note Holder or the Depositary in identifying the beneficial owners of
Notes and the Company and the Trustee may conclusively rely on, and will be
protected in relying on, instructions from the Global Note Holder or the
Depositary for all purposes.
 
    SAME-DAY SETTLEMENT AND PAYMENT
 
    The Indenture will require that payments in respect of the Notes represented
by the Global Notes (including principal, premium, if any, and interest) be made
by wire transfer of immediately available funds to the accounts specified by the
Global Note Holder. With respect to Certificated Notes, the Company will make
all payments of principal, premium, if any, and interest by wire transfer of
immediately available funds to the accounts specified by the Holders thereof or,
if no such account is specified, by mailing a check to each Holder's registered
address. Notes represented by the Global Notes are expected to be eligible to
trade in the PORTAL market and to trade in the Depositary's Same-Day Funds
Settlement System, and any permitted secondary market trading activity in such
Notes will, therefore, be required by the Depositary to be settled in
immediately available funds. The Company expects that secondary trading in the
Certificated Notes will also be settled in immediately available funds.
 
    Because of time zone differences, the securities account of a Euroclear or
Cedel Bank participant purchasing an interest in a Global Note from a
Participant in the Depositary will be credited, and any such crediting will be
reported to the relevant Euroclear or Cedel Bank participant, during the
securities settlement processing day (which must be a business day for Euroclear
or Cedel Bank) immediately following the settlement date of the Depositary. The
Depositary has advised the Company that cash received in Euroclear or Cedel Bank
as a result of sales of interests in a Global Note by or through a Euroclear or
Cedel Bank participant to a Participant will be received with value on the
settlement date of the Depositary but will be available in the relevant
Euroclear or Cedel Bank cash account only as of the business day for Euroclear
or Cedel Bank following the Depositary's settlement date.

       CERTAIN U.S. FEDERAL TAX CONSEQUENCES TO NON-UNITED STATES HOLDERS
 
    The following summary describes the material anticipated U.S. federal income
tax consequences of the purchase, ownership and disposition of the Notes by
Non-United States Holders (as defined below). Except where noted, it deals only
with Notes held as capital assets within the meaning of Section 1221 of the
Internal Revenue Code of 1986, as amended (the "Code"), and does not discuss all
of the tax consequences that may be relevant to a holder in light of his
particular circumstances. Furthermore, the discussion below is based upon the
provisions of the Code and regulations, administrative and judicial decisions
thereunder as of the date hereof, and such authorities may be repealed, revoked
or modified with possible retroactive effect so as to result in U.S. federal
income tax consequences different from those discussed below.
 
    As used herein, "Non-United States Holder" or "Non-U.S. Holder" means any
person or entity that is, as to the United States, a foreign corporation, a
nonresident alien individual, a nonresident fiduciary of a foreign estate or
trust or a foreign partnership one or more of the members of which is, as to the
United States, a foreign corporation, a nonresident alien individual or a
nonresident fiduciary of a foreign estate or trust.
 
    ALL PROSPECTIVE PURCHASERS ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE PURCHASE
OWNERSHIP AND DISPOSITION OF THE NOTES.
 
TAXATION OF INTEREST ON THE NOTES
 
    If a Non-U.S. Holder of a Note does not satisfy all of the conditions
discussed in the next paragraph, the Non-U.S. Holder will be subject to a 30%
U.S. federal withholding tax with respect to payments of interest on the Note
(the "30% U.S. Withholding Tax"). If applicable to a Non-U.S. Holder of a Note,
the 30% U.S. Withholding Tax must be withheld by the Company or its paying agent
from any payments of interest with respect to the Note.
 
    The 30% U.S. Withholding Tax is not applicable to payments of interest with
respect to a Note, if the Non-U.S. Holder of the Note (i) does not actually or
constructively own 10% or more of the total combined voting power of all classes
of stock of the Company entitled to vote within the meaning of Section 871(h)(3)
of the Code and the regulations thereunder, (ii) is not a controlled foreign
corporation related, directly or indirectly, to the Company through stock
ownership, (iii) is not a bank whose receipt of interest on a Note is described
in Section 881(c)(3)(A) of the Code and (iv) satisfies the statement requirement
set forth in Sections 871(h) and 881(c) of the Code and the Treasury Regulations
thereunder (the "Statement Requirement").
 
    To satisfy the Statement Requirement, the Non-U.S. Holder of a Note or a
financial institution holding the Note on behalf of such Non-U.S. Holder must
provide, in accordance with specified procedures, the Company or its paying
agent with a statement to the effect that the beneficial owner of the Note is
not a U.S. person. These requirements will be met if (x) the Non-U.S. Holder
provides his name and address, and certifies, under penalties of perjury, that
he is not a U.S. person (which certification may be made on an IRS Form W-8 or
Form W-8IMY (or substitute form)) or (y) a financial institution holding the
Note on behalf of the Non-U.S. Holder certifies, under penalties of perjury,
that such statement has been received by it and furnishes a paying agent with a
copy thereof.
 
    With respect to Notes held by a foreign partnership, under current law, the
IRS Form W-8 or Form W-8IMY (or substitute form) may be provided by the foreign
partnership. However, for interest and sale proceeds paid with respect to a Note
after December 31, 1999, unless the foreign partnership has entered into a
withholding agreement with the IRS, a foreign partnership will be required, in
addition to providing an intermediary IRS Form W-8 (or substitute form), to
attach an appropriate certification by each partner. Treasury Regulations
generally effective for payments made after December 31, 1999, modify
 
                                       98
<PAGE>
certain of the Statement Requirements. It is possible that the Company and other
withholding agents may request a new withholding exemption form from holders in
order to qualify for continued exemption from withholding under the Treasury
Regulations when they become effective. Prospective investors, including foreign
partnerships and their partners, should consult their tax advisors regarding
possible additional reporting requirements.
 
    The 30% U.S. Withholding Tax is not imposed or may be reduced or eliminated
with respect to the payments of interest on a Note, if the Company or its paying
agent receives IRS Form 4224 or Form W-8ECI (or substitute form) or IRS Form
1001 or Form W8BEN (or substitute form) (or, after December 31, 1999, IRS Form
W-8 or Form W-8IMY (or substitute form)) from the Non-U.S. Holder of the Note,
establishing, unless the Company has knowledge to the contrary, either (i) that
interest paid on the Note is effectively connected with the conduct of a trade
or business in the U.S. or (ii) that a tax treaty applies to reduce the rate of,
or eliminate, the withholding tax, respectively. Interest paid to a Non-U.S.
Holder that is effectively connected with the conduct by the holder of a trade
or business in the U.S. is generally taxed on a net income basis at the
graduated rates that are applicable to U.S. persons. In the case of a Non-U.S.
Holder that is a corporation, such effectively connected income may also be
subject to the U.S. federal branch profits tax (which is generally imposed on a
foreign corporation on the deemed repatriation from the U.S. of effectively
connected earnings and profits) at a 30% rate (unless the rate is reduced or
eliminated by an applicable income tax treaty and the holder is a qualified
resident of the treaty country).
 
SALE, EXCHANGE OR OTHER DISPOSITION OF NOTES
 
    A Non-U.S. Holder will generally not be subject to U.S. federal income or
withholding tax with respect to capital gain recognized on a sale, exchange or
other disposition of the Notes unless (i) the gain is effectively connected with
a trade or business of the Non-U.S. Holder in the U.S., (ii) in the case of a
Non-U.S. Holder who is an individual, such holder is present in the U.S. for 183
or more days in the taxable year of the sale or other disposition and certain
other conditions are met, or (iii) the Non-U.S. Holder is subject to tax
pursuant to certain provisions of the Code applicable to U.S. expatriates.
 
    Gain recognized by a Non-U.S. Holder on a sale, exchange or other
disposition of the Notes that is effectively connected with the conduct by the
Holder of a trade or business in the U.S. is generally taxed on a net income
basis at the graduated rates that are applicable to U.S. persons. In the case of
a Non-U.S. Holder that is a corporation, such effectively connected income may
also be subject to the U.S. branch profits tax (which is generally imposed on a
foreign corporation on the deemed repatriation from the United States of
effectively connected earnings and profits) at a 30% rate (unless the rate is
reduced or eliminated by an applicable income tax treaty and the Holder is a
qualified resident of the treaty country).
 
    The exchange of a Note by a Non-U.S. Holder for an Exchange Note pursuant to
the Exchange Offer should not constitute a taxable exchange. A Non-U.S. Holder
should have the same tax basis and holding period in the Exchange Note as it did
in the Note.
 
FEDERAL ESTATE TAX
 
    A Note beneficially owned by an individual who at the time of death is a
Non-U.S. Holder will not be subject to U.S. federal estate tax as a result of
such individual's death, provided that such individual does not actually or
constructively own 10% or more of the total combined voting power of all classes
of stock of the Company entitled to vote within the meaning of Section 871(h)(3)
of the Code and provided that the interest payments with respect to such Note
would not have been, if received at the time of such individual's death,
effectively connected with the conduct of a U.S. trade or business by such
individual.
 
                                       99
<PAGE>
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    No information reporting or backup withholding will be required with respect
to payments made by the Company or its paying agent to a Non-U.S. Holder if the
Statement Requirement has been met and the payor does not have actual knowledge
that the Non-U.S. Holder is a U.S. person.
 
    In addition, information reporting and backup withholding will not apply if
payments on a Note are paid or collected by a foreign office of a nominee,
custodian or other foreign agent on behalf of the beneficial owner of such Note,
or if a foreign office of a broker pays the proceeds of the sale of a Note to
the beneficial owner thereof. However, payments made or collected by such
nominee, custodian, agent or broker that is, for U.S. federal income tax
purposes, (i) a U.S. person, (ii) a controlled foreign corporation, or a foreign
person 50% or more of whose gross income is effectively connected with a U.S.
trade or business for a specified three year period, or (iii) (with respect to
payments made after December 31, 1999) a foreign partnership with certain
connections to the U.S., will be subject to information reporting (but not
backup withholding) unless such nominee, custodian, agent or broker has in its
records documentary evidence that the beneficial owner is not a U.S. person and
certain other conditions are met, or the beneficial owner otherwise establishes
an exemption. Backup withholding may apply to any payment that such broker is
required to report if the broker has actual knowledge that the payee is a U.S.
person. Payments to or through the U.S. office of a broker will be subject to
information reporting and backup withholding unless the Holder certifies, under
penalties of perjury, that it is not a U.S. person or otherwise establishes an
exemption.
 
    Treasury Regulations generally effective for payments made after December
31, 1999, modify certain of the certification requirements for backup
withholding. It is possible that the Company and other withholding agents may
request a new withholding exemption form from holders in order to qualify for
continued exemption from backup withholding under the Treasury Regulations when
they become effective. Non-U.S. Holders should consult their own tax advisors
regarding the application of information reporting and backup withholding in
their particular situations, the availability of an exemption therefrom, and the
procedures for obtaining such an exemption, if available. Any amounts withheld
under the backup withholding rules generally will be allowed as a refund or
credit against the Non-U.S. Holder's U.S. federal income tax liability and may
entitle such Holder to a refund, provided the required information is furnished
to the IRS.
 
                              PLAN OF DISTRIBUTION
 
    There has previously been only a limited secondary market and no public
market for the Old Notes. The Company does not intend to apply for the listing
of the Notes on a national securities exchange or for their quotation through
The Nasdaq Stock Market. The Notes are eligible for trading in the PORTAL
market. The Company has been advised by the Initial Purchasers that the Initial
Purchasers currently intend to make a market in the Notes; however, no Initial
Purchaser is obligated to do so and any market making may be discontinued by any
Initial Purchaser at any time. In addition, such market making activity may be
limited during the Exchange Offer. Therefore, there can be no assurance that an
active market for the Old Notes or the New Notes will develop. If a trading
market does not develop or is not maintained, holders of Notes may experience
difficulty in reselling Notes. If a trading market develops for the Notes,
future trading prices of such securities will depend on many factors, including,
among other things, prevailing interest rates, the Company's results of
operations and the market for similar securities. Depending on such factors,
such securities may trade at a discount from their offering price.
 
    BROKER-DEALERS WHO DID NOT ACQUIRE OLD NOTES AS A RESULT OF MARKET MAKING
ACTIVITIES OR TRADING ACTIVITIES MAY NOT PARTICIPATE IN THE EXCHANGE OFFER.
 
    With respect to resale of New Notes, based on an interpretation by the staff
of the Commission set forth in no-action letters issued to third parties, the
Company believes that a holder (other than a person
 
                                      100
<PAGE>
that is an affiliate of the Company within the meaning of Rule 405 under the
Securities Act or a "broker" or "dealer" registered under the Exchange Act) who
exchanges Old Notes for New Notes in the ordinary course of business and who is
not participating, does not intend to participate, and has no arrangement or
understanding with any person to participate, in the distribution of the New
Notes, will be allowed to resell the New Notes to the public without further
registration under the Securities Act and without delivering to the purchasers
of the New Notes a prospectus that satisfies the requirements of Section 10
thereof. However, if any holder acquires New Notes in the Exchange Offer for the
purpose of distributing or participating in a distribution of the New Notes,
such holder cannot rely on the position of the staff of the Commission
enunciated in EXXON CAPITAL HOLDINGS CORPORATION (available May 13, 1988) or
similar no-action letters or any similar interpretive letters and must comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with a secondary resale transaction, unless an exemption from
registration is otherwise available.
 
    As contemplated by the no-action letters mentioned above and the
Registration Rights Agreement, each holder accepting the Exchange Offer is
required to represent to the Company in the Letter of Transmittal that (i) the
New Notes are to be acquired by the holder in the ordinary course of business,
(ii) the holder is not engaging and does not intend to engage in the
distribution of the New Notes, and (iii) the holder acknowledges that, if such
holder participates in the Exchange Offer for the purpose of distributing the
New Notes, such holder must comply with the registration and prospectus delivery
requirements of the Securities Act and cannot rely on the above no-action
letters.
 
    Any broker or dealer registered under the Exchange Act (each a
"Broker-Dealer") who holds Old Notes that were acquired for its own account as a
result of market-making activities or other trading activities (other than Old
Notes acquired directly from the Company or an affiliate of the Company) may
exchange such Old Notes for New Notes pursuant to the Exchange Offer, however,
such Broker-Dealer may be deemed an underwriter within the meaning of the
Securities Act and, therefore, must deliver a prospectus meeting the
requirements of the Securities Act in connection with any resales of the New
Notes received by it in the Exchange Offer, which prospectus delivery
requirement may be satisfied by the delivery by such Broker-Dealer of this
Prospectus. The Company has agreed to cause the Exchange Offer Registration
Statement, of which this Prospectus is a part, to remain continuously effective
for a period of 180 days, if required, from the Exchange Date, and to make this
Prospectus, as amended or supplemented, available to any such Broker-Dealer for
use in connection with resales. Any Broker-Dealer participating in the Exchange
Offer will be required to acknowledge that it will deliver a prospectus meeting
the requirements of the Securities Act in connection with any resales of New
Notes received by it in the Exchange Offer. The delivery by a Broker-Dealer of a
prospectus in connection with resales of New Notes shall not be deemed to be an
admission by such Broker-Dealer that it is an underwriter within the meaning of
the Securities Act. The Company will not receive any proceeds from any sale of
New Notes by a Broker-Dealer.
 
    New Notes received by Broker-Dealers for their own account pursuant to the
Exchange Offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the New Notes or a combination of such methods of resale, at market
prices prevailing at the time of resale, at prices related to such prevailing
market prices or negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such Broker-Dealer and/or the
purchasers of any such New Notes.
 
                                 LEGAL MATTERS
 
    Certain legal matters with respect to the validity of the Notes are being
passed upon for the Company by McAfee & Taft A Professional Corporation,
Oklahoma City, Oklahoma.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
 
Sygnet Wireless, Inc.
 
    We have audited the accompanying consolidated balance sheets of Sygnet
Wireless, Inc. as of December 31, 1996 and 1997, and the related consolidated
statements of operations, shareholders' equity (deficit), and cash flows for
each of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Sygnet
Wireless, Inc. at December 31, 1996 and 1997 and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1997 in conformity with generally accepted accounting principles.

the "Company") thereafter. The Company owns and operates cellular telephone
systems serving one large cluster with an approximate population of 2.4 million
in Northeastern Ohio, Western Pennsylvania and Western New York.
 
    On August 19, 1996, the shareholders of Sygnet and Wilcom effected a
corporate restructuring whereby Wilcom was merged into Sygnet and shareholders
of Wilcom received 8.72 shares of Sygnet common stock for each share of Wilcom
common stock held as of August 31, 1996, the effective date of the merger. This
merger was a business combination between entities under common control whereby
the assets and liabilities so transferred were accounted for at historical cost
in a manner similar to that in pooling-of-interest accounting. Also, in
conjunction with this merger, the shareholders of Sygnet amended the articles of
incorporation to change Sygnet's name to Sygnet Wireless, Inc.
 
    Prior to the restructuring, Sygnet and Wilcom had been operating their
cellular business through three partnerships (Youngstown Cellular Telephone
Company ("YCTC")), Erie Cellular Telephone Company ("Erie"), and Wilcom
Cellular) and Sharon--Youngstown Cellular, Inc. ("Sharon"). As a result of the
restructuring and merger, Sharon was renamed Sygnet and is the wholly-owned
subsidiary and operating company of Sygnet Wireless, Inc. The existence of YCTC,
Erie, and Wilcom Cellular terminated on October 1, 1996 when all partnership
interests transferred to Sygnet.
 
2. RECENTLY ISSUED ACCOUNTING STANDARDS
 
    In June 1997, the FASB issued Statement No. 130, REPORTING COMPREHENSIVE
INCOME, which is required to be adopted effective January 1, 1998. This
Statement establishes standards for the reporting and display of comprehensive
income and its components in a full set of general purpose financial statements.
Reclassification of financial statements for earlier periods presented is
required. The impact of Statement No. 130 on the Company's financial statements
is not expected to be material.
 
    In June 1997, the FASB also issued Statement No. 131, DISCLOSURES ABOUT
SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION, which is required to be
adopted effective January 1, 1998. This Statement changes the way companies
report selected segment information in annual financial statements and also
requires those companies to report selected segment information in interim
financial reports to shareholders. The impact of Statement No. 131 on the
Company's financial statement disclosures is not expected to be material.
 
3. ACQUISITIONS
 
    On October 9, 1996, the Company acquired certain cellular licenses,
property, equipment, customer lists, current assets and current liabilities of
Horizon Cellular Telephone Company of Chautauqua L.P., Horizon Cellular
Telephone Company of Crawford L.P., and Horizon Cellular Telephone Company of
Indiana L.P. (hereinafter collectively referred to as "Horizon") for cash of
$252.9 million. The acquired systems provide cellular service to an estimated
population of 1.4 million in contiguous markets in Western Pennsylvania and
Western New York.

    INTANGIBLE ASSETS
 
    The FCC issues licenses that enable cellular carriers to provide cellular
service in specific geographic areas. The FCC grants licenses for a term of up
to 10 years and generally grants renewals if the licensee has complied with its
obligations under the Communications Act of 1934. In 1993, the FCC adopted
specific standards to apply to cellular renewals, concluding it will award a
renewal to a cellular licensee that meets certain standards of past performance.
Historically, the FCC has granted license renewals routinely. The Company
believes that it has met, and will continue to meet all requirements necessary
to secure renewal of its cellular licenses.
 
    The Company has acquired cellular licenses and customer lists through its
acquisition of interests in various cellular systems. The cost of licenses and
customer lists acquired was $231,003,426 in 1996. The Company uses a 40 year
useful life to amortize its licenses under the straight-line method. Purchased
cellular and paging customer lists are being amortized over 5 years under the
straight-line method. The components of intangible assets at December 31 are
summarized below:

    Amortization expense was $523,768, $3,652,470 and $11,559,031 in 1995, 1996
and 1997, respectively.
 
    The ongoing value and remaining useful lives of intangible and other
long-term assets are subject to periodic evaluation and the Company currently
expects the carrying amounts to be fully recoverable. When events and
circumstances indicate that intangible and other long-term assets might be
impaired, an undiscounted cash flow methodology would be used to determine
whether an impairment loss would be recognized.
 
    REVENUE RECOGNITION
 
    The Company earns revenue primarily by providing cellular services to its
customers (Subscriber Revenue) and from the usage of its system by the customers
of other cellular carriers (Roamer Revenue). Access revenue for Subscriber
Revenue is billed one month in advance. Revenue is recognized as service is
rendered. Subscriber acquisition costs (primarily commissions and loss on
equipment sales) are expensed when incurred.

    DEFERRED FINANCING COSTS
 
    Deferred financing costs are being amortized over the terms of the bank
credit facility and senior notes. Accumulated amortization was $266,084 and
$1,409,754 at December 31, 1996 and 1997, respectively. Amortization expense was
$196,170, $437,276 and $1,141,065 in 1995, 1996 and 1997, respectively. Upon
entering into a new bank credit facility in October 1996, an extraordinary loss
of $1,420,864 was incurred to write-off unamortized financing costs under the
extinguished bank credit agreement as described in Note 6.
 
    ADVERTISING COSTS
 
    Advertising costs are recorded as expense when incurred. Advertising expense
was $933,498, $1,225,151 and $1,841,138 in 1995, 1996 and 1997, respectively.
 
    NET LOSS PER COMMON SHARE
 
    In 1997, the Company adopted FASB Statement No. 128, EARNINGS PER SHARE,
which replaced the computation of primary and fully diluted earnings per share
with basic and diluted earnings per share. No restatement of prior year earnings
per share amounts was necessary since the impact was not significant.
 
    Net loss per share is computed using the weighted average number of shares
of common stock outstanding during the period. The pro forma net loss per share
for 1996 is based on the number of common shares outstanding, as if the
corporate restructuring described in Note 1 occurred at the beginning of the
year. The effect of stock options is not included in the computation of dilutive
earnings per share since it is anti-dilutive.
 
    Losses applicable to common shareholders include adjustments for Preferred
Stock dividends and accretions and the excess of the redemption price paid over
the carrying value of the Preferred Stock. Earnings per share for 1995 is not
presented because such data prior to the restructuring described in Note 1 is
not meaningful.
 
    STOCK COMPENSATION
 
    The Company accounts for its stock-based employee compensation arrangements
based on the intrinsic value of the equity instruments granted, as set forth in
APB Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES.
 
    USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements. Actual
results may differ from those estimates.
 
    SIGNIFICANT CONCENTRATIONS
 
    In connection with providing cellular services to customers of other
cellular carriers, the Company has contractual agreements with those carriers
which provide for agreed upon billing rates between the parties. Approximately
62%, 48% and 43% of the Company's Roamer Revenue was earned from two cellular
carriers in 1995, 1996 and 1997, respectively.

4. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    FINANCIAL INSTRUMENTS
 
    Derivative financial instruments are used by the Company in the management
of interest rate exposure and are accounted for on an accrual basis. Income and
expense are recorded in the same category as that arising from the related
liability being hedged (i.e., adjustments to interest expense).
 
    The Company uses variable interest rate credit facilities to finance
acquisitions and operations of the Company. The Company may reduce its exposure
to fluctuations in interest rates by creating offsetting positions through the
use of derivative financial instruments. The Company does not use derivative
financial instruments for trading or speculative purposes, nor is the Company a
party to leveraged derivatives. The notional amount of interest rate swaps is
the underlying principal amount used in determining the interest payments
exchanged over the life of the swap. The notional amount is not a measure of the
Company's exposure through its use of derivatives.
 
    The Company may be exposed to credit loss in the event of nonperformance by
the counterparties to its interest rate swap agreements. The Company anticipates
the counterparties will be able to fully satisfy its obligations under the
agreements.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    At December 31, 1996 and 1997, the carrying value of cash equivalents,
accounts receivable, the interest rate swap and the long-term bank debt
approximated fair value. The fair value of the long-term unsecured senior notes,
calculated based on quoted market prices, was $112,750,000 and $118,800,000 at
December 31, 1996 and 1997, respectively.

6. LONG-TERM DEBT
 
    On September 19, 1996, the Company issued $110,000,000 11 1/2% unsecured
Senior Notes due October 1, 2006 (the Notes). The Notes pay interest
semiannually on April 1 and October 1 of each year commencing April 1, 1997. The
Notes are redeemable at the option of the Company at redemption prices
(expressed as a percentage of principal amount) ranging from 105.75% in 2001 to
100.00% in 2005 and thereafter. Among other things, the Notes contain certain
covenants which limit additional indebtedness, payment of dividends, sale of
assets or stock, changes in control and transactions with related parties. The
proceeds from the Notes were used to repay amounts borrowed under a $75 million
bank credit agreement and to finance the acquisition of Horizon described in
Note 3.
 
    On October 9, 1996, Sygnet entered into a new financing agreement (the Bank
Credit Facility) with a commercial bank group. The Bank Credit Facility is a
senior secured reducing revolver that provides Sygnet the ability to borrow up
to $300.0 million through June 30, 1999. Mandatory reductions in the revolver
occur quarterly thereafter through June 30, 2005, when the Bank Credit Facility
terminates. The Bank Credit Facility is secured by certain assets and the stock
of Sygnet. The Bank Credit Facility provides for various borrowing rate options
based on either a fixed spread over the London Interbank Offered Rate (LIBOR) or
the prime rate. Interest payments are made quarterly. As of December 31, 1997,
$195.5 million was outstanding under the Bank Credit Facility.
 
    Among other things, the Bank Credit Facility contains financial covenants
which require the maintenance of debt service ratios and the hedging of interest
rate risk and limit distributions to shareholders and sales of assets. In
connection with these covenants, the Company has a three year interest rate swap
with a total underlying notional amount of $80 million. The swap agreements
converted the interest rate on $80 million notional amount of the credit
facility from a variable rate based upon a three month LIBOR (5.81% at December
31, 1997) to fixed rates ranging from 5.79% to 6.03%. Amounts paid or received
under these agreements are recognized as adjustments to interest expense.

8. RETIREMENT PLAN
 
    The Company sponsors a 401(k) retirement and profit sharing plan which
covers substantially all its employees. Eligible employees can contribute from
1% to 15% of their compensation. The Company, at its discretion, may match a
portion of the employee's contribution. The Company may also, at its discretion,
make additional profit sharing contributions to the plan. Total pension expense
was $114,000, $181,000 and $293,000 in 1995, 1996 and 1997, respectively.
 
9. REDEEMABLE PREFERRED STOCK AND WARRANTS
 
    On April 3, 1997, 100,000 shares of Series A Senior Cumulative Nonvoting
Preferred Stock (Preferred Stock) were redeemed by the Company at a cost of
$10,000,000 which was funded by the Bank Credit Facility. On June 20, 1997, the
remaining 118,394.51 shares of Preferred Stock were redeemed by the Company at a
cost of $11,839,451. This redemption was funded by the Common Stock Sale
described in Note 10.
 
    The Preferred Stock had a redemption value of $100 per share and was
recorded at fair value on the date of issuance less issuance costs. Dividends
were cumulative from the date of issuance, accrued quarterly in arrears and were
payable in shares of Preferred Stock. The dividend rates increased annually from
15% in 1997 to 21% in 2000 and thereafter. As of December 31, 1996, the Company
accrued stock dividends in the amount of $690,411 (which represented 6,904
shares). The Preferred Stock included the potential issuance of warrants to
purchase shares of the Company's Class A Common Stock. For financial reporting
purposes, the estimated fair value of the warrants was included with the
Preferred Stock in the accompanying balance sheet and the excess of the
redemption value of the Preferred Stock over the carrying value was accreted by
periodic charges to additional paid-in capital over the life of the issue. No
warrants were issued.
 
    The Company has authorized 5 million shares of Nonvoting Preferred Stock,
par value $.01 per share, of which 500,000 are designated as Series A Senior
Cumulative Nonvoting Preferred Stock.

    The Company has also authorized 10 million shares of Voting Preferred Stock,
par value $.01 per share, none of which are issued as of December 31, 1997.
 
10. SHAREHOLDERS' EQUITY
 
    On June 20, 1997, the Company issued and sold 3,000,000 shares of Class A
Common Stock, $.01 par value, to Boston Ventures Limited Partnership V (Boston
Ventures) at a price of $15 per share (Common Stock Sales). The proceeds of
$43.6 million, net of issuance fees of $1.4 million, were used to redeem the
remaining outstanding Preferred Stock as described in Note 9, and to reduce
amounts outstanding under the Bank Credit Facility. As a condition of the Common
Stock Sales, Boston Ventures appointed two representatives on the Company's
eleven member board of directors.
 
    In August 1997, Boston Ventures purchased 1,000,000 shares of Class B Common
Stock from shareholders pursuant to a tender offer which upon purchase based on
the requirements of the corporate restructuring described in Note 1, became
Class A Common Stock.
 
    On August 28, 1996, the Company approved a plan to recapitalize the Company
whereby the Sygnet common stock Type A (205,698 shares) and Type B (1,028,428
shares) were converted into 6,170,630 shares of Sygnet Wireless, Inc. Class B
common stock in a 5 for 1 split, effective on September 20, 1996. These shares
are entitled to ten votes per share.
 
    On January 5, 1995, Sygnet repurchased 8,024 Type A shares for $39.00 per
share and 40,173 Type B shares for $35.00 per share from a shareholder for
approximately $1,719,000. These shares were accounted for at cost and held as
treasury stock until August 28, 1996 when they were retired.
 
    Under the most restrictive of the covenants discussed in Note 6, the Company
could not declare any additional dividends on its common stock at December 31,
1997.
 
    On December 29, 1994, the Company received a promissory note from an
officer/shareholder for $249,952 for the purchase of common shares from a
shareholder. The note requires annual payment of interest at 8.23% with
principal repayment commencing on December 31, 1998 through December 31, 2001.
 
11. INCOME TAXES
 
    On August 31, 1996, Sygnet and Wilcom terminated their status as Subchapter
S Corporations. As a result of this termination, application of the provisions
of Statement of Financial Accounting Standards No. 109, ACCOUNTING FOR INCOME
TAXES, requires deferred income taxes to be provided for differences in the
basis for tax purposes and for financial accounting purposes of recorded assets
and liabilities. As a result of the termination of their Subchapter S
Corporation status, Sygnet and Wilcom contributed their undistributed earnings
to additional paid-in capital. At December 31, 1997, the Company has net
operating loss carryforwards of $28.7 million that expire in 2011 and 2012. For
financial reporting purposes, a valuation allowance of $7,747,300 has been
recognized to offset the net deferred tax assets which primarily relate to the
net operating loss carryforward.

12. STOCK OPTION PLAN
 
    The Company has stock option plans that provide for the purchase of Class A
common stock by employees and directors of the Company. Under the stock option
plans the Company is authorized to issue 1,250,000 options for the purchase of
shares of Class A common stock (1,000,000 for employees and 250,000 for
non-employee directors). These options vest over a period ranging from grant
date to five years, are exercisable based upon the terms of the grants and
expire at the end of ten years. The Company applies APBO No. 25, ACCOUNTING FOR
STOCK ISSUED TO EMPLOYEES and related Interpretations in accounting for the
plan, which requires that for certain options granted, the Company recognizes as
compensation expense the excess of the deemed fair value for accounting purposes
of the common stock over the exercise price of the options. For the majority of
options, no compensation cost has been recognized. Had compensation plans been
determined based on the fair value at the grant dates for awards under those
plans consistent with the method of SFAS No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION, the Company's net loss and net loss per share would not have been
materially different from the amounts reported.

12. STOCK OPTION PLAN (CONTINUED)
    For pro forma calculations the fair value of each option is estimated on the
date of grant using the Minimum Value option-pricing model with the following
weighted-average assumptions used for grants in both 1996 and 1997: risk-free
interest rates ranging from 5.9% to 6.9% and average expected lives ranging from
5.25 to 7.5 years for issued options.

31, 1996 and 1997 and changes during the years then ended is presented below:

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                                  (UNAUDITED)
 
1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
 
    These financial statements include the consolidated accounts of Sygnet
Wireless, Inc. (the "Company") and its wholly-owned subsidiary Sygnet
Communications, Inc. ("Sygnet"). The Company owns and operates cellular
telephone systems serving one large cluster with an approximate population of
2.4 million in Northeastern Ohio, Western Pennsylvania and Western New York.
 
    The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the nine-month period ended September 30,
1998 are not necessarily indicative of the results that may be expected for the
year ended December 31, 1998. For further information, refer to the consolidated
financial statements and notes thereto included in the Company's annual report
on Form 10-K for the fiscal year ended December 31, 1997 (File No. 333-10161)
filed with the Securities and Exchange Commission.
 
2. AGREEMENT AND PLAN OF MERGER
 
    On July 28, 1998, the Company entered into an Agreement and Plan of Merger
("Merger") with a subsidiary of Dobson Communications Corporation ("Dobson")
pursuant to which Dobson will acquire all outstanding shares of common stock of
the Company for an aggregate amount of $337.5 million, or approximately $34.51
per share. The agreement is pending regulatory approval and is expected to close
in the fourth quarter of 1998.
 
3. LONG-TERM DEBT
 
    The Company has $110.0 million 11 1/2% unsecured Senior Notes due October 1,
2006 (the "Notes"). The Notes pay interest semiannually on April 1 and October 1
of each year. The Notes are redeemable at the option of the Company at
redemption prices (expressed as a percentage of principal amount) ranging from
105.75% in 2001 to 100.00% in 2005 and thereafter. Among other things, the Notes
contain certain covenants which limit additional indebtedness, payment of
dividends, sale of assets or stock, changes in control and transactions with
related parties.
 
    Sygnet has a financing agreement (the "Bank Credit Facility") with a
commercial bank group. The Bank Credit Facility is a senior secured reducing
revolver that provides Sygnet the ability to borrow up to $300.0 million through
June 30, 1999. Mandatory reductions in the revolver occur quarterly thereafter
through June 30, 2005, when the Bank Credit Facility terminates. The Bank Credit
Facility is secured by certain assets and the stock of Sygnet. The Bank Credit
Facility provides for various borrowing rate options based on either a fixed
spread over the London Interbank Offered Rate (LIBOR) or the prime rate. As of
September 30, 1998, the amount outstanding under the Bank Credit Facility is
$192.6 million.
 
4. REDEEMABLE PREFERRED STOCK AND WARRANTS
 
    On April 3, 1997, 100,000 shares of Series A Senior Cumulative Nonvoting
Preferred Stock ("Preferred Stock"), were redeemed by the Company at a cost of
$10.0 million which was funded by the Bank Credit Facility. On June 20, 1997,
the remaining 118,394.51 shares of Preferred Stock were redeemed by

                                  (UNAUDITED)
 
4. REDEEMABLE PREFERRED STOCK AND WARRANTS (CONTINUED)
the Company at a cost of $11,839,451. This redemption was funded by the Common
Stock Sale described in Note 5.
 
    The Preferred Stock had a redemption value of $100 per share and was
recorded at fair value on the date of issuance less issuance costs. Dividends
were cumulative from the date of issuance, accrued quarterly in arrears and were
payable in shares of Preferred Stock. The dividend rates increased annually from
15% in 1997 to 21% in 2000 and thereafter. The Preferred Stock included the
potential issuance of warrants to purchase shares of the Company's Class A
Common Stock. For financial reporting purposes, the estimated fair value of the
warrants was included with the Preferred Stock in the accompanying balance sheet
and the excess of the redemption value of the Preferred Stock over the carrying
value was accreted by periodic charges to additional paid-in capital over the
life of the issue. No warrants were issued.
 
    The Company has authorized 5 million shares of Nonvoting Preferred Stock,
par value $.01 per share, of which 500,000 are designated as Series A Senior
Cumulative Nonvoting Preferred Stock.
 
5. SHAREHOLDERS EQUITY
 
    On June 20, 1997, the Company issued and sold 3,000,000 shares of Class A
Common Stock, $.01 par value, to Boston Ventures Limited Partnership V ("Boston
Ventures") at a price of $15 per share ("Common Stock Sale"). The proceeds of
$43.9 million, net of issuance fees, were used to redeem the remaining
outstanding Preferred Stock as described in Note 4, and to reduce amounts
outstanding under the Bank Credit Facility. As a condition of the Common Stock
Sale, Boston Ventures has two representatives on the Company's eleven member
board of directors.
 
    In August 1997, Boston Ventures purchased 1,000,000 shares of Class B Common
Stock from shareholders pursuant to a tender offer which, upon purchase, became
Class A Common Stock.
 
6. COMMITMENTS AND CONTINGENCIES
 
    In accordance with the Merger (see Note 2), the Company may be liable to pay
severance benefits and incentive compensation for an approximate amount of $1.9

                             NOTES TO BALANCE SHEET
 
                               SEPTEMBER 30, 1998
 
1. ORGANIZATION:
 
    The Company was incorporated under the name Front Nine Holdings, Inc. as an
Oklahoma corporation on July 23, 1998. Subsequently, the Company changed its
name to Dobson/Sygnet Communications Company (the "Company") and amended its
certificate of incorporation on December 2, 1998 to reflect this change. The
Company is a wholly owned subsidiary of Dobson Communications Corporation
("Dobson Communications").
 
CAPITAL RESOURCES AND GROWTH
 
    The Company's total indebtedness and debt service requirements will
substantially increase as a result of the transactions described in Note 3, and
the Company will be subject to significant financial restrictions and
limitations. If the Company is unable to borrow sufficient funds through bank
financing, capital contributions from Dobson Communications and the senior notes
described in Note 3, the Company may be unable to borrow additional funds from
other sources during such time period to fund planned capital expenditures, its
ongoing operations or other permissible uses.
 
    The Company's ability to manage future growth will depend upon its ability
to monitor operations, control costs, maintain effective quality controls and
significantly expand the Company's internal management, technical and accounting
systems, all of which will result in higher operating expenses. Any failure to
expand these areas and to implement and improve such systems, procedures and
controls in an efficient manner at a pace consistent with the growth of the
Company's business could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
    The Company's cash flows currently are entirely dependent upon Dobson
Communications and such dependency will continue at least until such time as the
Company completes the merger of Sygnet's operations into the Company.
 
2. SIGNIFICANT ACCOUNTING POLICIES:
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents on the accompanying balance sheet includes cash
and short-term investments with original maturities of three months or less.
 
3. ACQUISITIONS:
 
    On July 28, 1998, Dobson/Sygnet Operating Company ("Operating"), an
affiliate of the Company entered into a definitive agreement to acquire the
stock of Sygnet for $337.5 million. Sygnet owns and operates cellular systems in
Ohio, Pennsylvania and New York covering an estimated population base of 2.4
million people. In connection with the acquisition, Operating plans to redeem
Sygnet's senior notes ($110 million at September 30, 1998) and refinance
Sygnet's credit facility ($192.6 million at September 30, 1998) herein referred
to as the ("Refinancings"). In connection with the Sygnet acquisition, Operating
will also be required to finance the acquisition of Pennsylvania 2 RSA for $6.0
million.
 
    In July 1998, Operating placed $25 million into escrow pending the close of
the Sygnet acquisition. The Company expects to finance the remaining purchase,
consisting of the remaining $312.5 million of stock, the Refinancings and the
Pennsylvania 2 RSA acquisition, through a combination of bank financing
described in Note 4, capital contributions from Dobson Communications and the
issuance of senior notes.

                               SEPTEMBER 30, 1998
 
3. ACQUISITIONS: (CONTINUED)
Upon the issuance of senior notes by the Company, it will purchase the stock of
Operating and contribute the net proceeds of the senior notes offering to
Operating. The Sygnet and Pennsylvania 2 RSA acquisitions are expected to close
in the fourth quarter of 1998 or early in 1999.
 
4. LONG-TERM DEBT:
 
    In connection with the pending Sygnet acquisition, Operating received
commitments for a new $450.0 million credit facility to be secured by the assets
acquired in the Sygnet acquisition. Operating also obtained commitments for
bridge financing. Subsequent to September 30, 1998, the commitments for bridge
financing expired. In connection with the bridge financing, Operating incurred
$3.36 million in fees to obtain the bridge financing.

                               SEPTEMBER 30, 1998
 
1. ORGANIZATION:
 
    The Company was incorporated under the name SWI Acquisition Corp., as an
Ohio corporation on July 23, 1998. Subsequently, the Company changed its name to
Dobson/Sygnet Operating Company and amended its certificate of incorporation on
August 25, 1998 to reflect this change. The Company is a wholly owned subsidiary
of Dobson Communications Corporation ("Dobson Communications"). The Company
currently serves as the company for the pre-acquisition activity of Sygnet
Wireless, Inc. ("Sygnet") (See Note 3) and, upon consummation of the Sygnet
acquisition, will merge with Sygnet.
 
    CAPITAL RESOURCES AND GROWTH
 
    The Company's total indebtedness and debt service requirements will
substantially increase as a result of the transactions described in Note 3, and
the Company will be subject to significant financial restrictions and
limitations. If the Company is unable to raise sufficient funds through the bank
financing, capital contributions from Dobson Communications and the senior notes
issued by Dobson/Sygnet Communications Company described in Note 3, the Company
may be unable to borrow additional funds from other sources in the future to
fund planned capital expenditures, its ongoing operations or other permissible
uses.
 
    The Company's ability to manage future growth will depend upon its ability
to monitor operations, control costs, maintain effective quality controls and
significantly expand the Company's internal management, technical and accounting
systems, all of which will result in higher operating expenses. Any failure to
expand these areas and to implement and improve such systems, procedures and

Company's business could have a material adverse effect on the Company's
business, financial condition and results of operations.

    Cash and cash equivalents on the accompanying combined balance sheet
includes cash and short-term investments with original maturities of three
months or less.
 
    IMPAIRMENT OF LONG-LIVED ASSETS
 
    The Company assesses potential impairments of long-lived assets and certain
identifiable intangibles when there is evidence that events or changes in
circumstances indicate that an asset's carrying value may not be recoverable. An
impairment loss is recognized when the sum of the expected future net cash flows
is less than the carrying amount of the asset. No such losses have been
identified by the Company.
 
    DEFERRED COSTS
 
    Deferred costs consist primarily of fees incurred to secure long-term debt
and acquisition costs. Deferred financing costs will be amortized on a
straight-line basis over the term of the debt. Acquisition

3. ACQUISITIONS:
 
    On July 28, 1998, the Company entered into a definitive agreement to acquire
the stock of Sygnet for $337.5 million. Sygnet owns and operates cellular
systems in Ohio, Pennsylvania and New York covering an estimated population base
of 2.4 million people. In connection with the acquisition, the Company plans to
redeem Sygnet's senior notes ($110.0 million at September 30, 1998) and
refinance Sygnet's credit facility ($192.6 million at September 30, 1998) herein
referred to as the ("Refinancings"). In connection with the Sygnet acquisition,
the Company will also be required to finance the acquisition of Pennsylvania 2
RSA for $6.0 million.
 
    In July 1998, the Company placed $25.0 million into escrow pending the close
of the Sygnet acquisition. The Company expects to finance the remaining
purchase, consisting of the remaining $312.5 million of stock, the Refinancings
and the Pennsylvania 2 RSA acquisition, through a combination of bank financing
described in Note 4, capital contributions from Dobson Communications and the
issuance of senior notes by Communications. The Sygnet and Pennsylvania 2 RSA
acquisitions are expected to close in the fourth quarter of 1998 or early in
1999.
 
4. LONG-TERM DEBT:
 
    In connection with the pending Sygnet acquisition, the Company received
commitments for a new $450.0 million credit facility to be secured by the assets
acquired in the Sygnet acquisition. As part of the Sygnet acquisition, the
Company also obtained commitments for bridge financing. Subsequent to September

bridge financing, the Company incurred $3.36 million in fees to obtain the
bridge financing. These fees are reflected in deferred cost on the accompanying
balance sheet.
 
5. RELATED PARTY TRANSACTIONS
 
    The Company had payables to Dobson Communications and certain of its
subsidiaries totaling $25.0 million at September 30, 1998 representing advances
related to the Sygnet acquisition described in Note 3. The Company expects to
repay these advances in connection with consummation of the acquisition with
proceeds from long-term debt. Accordingly, the payables to these affiliates have
been reflected as a non-current liability in the accompanying balance sheet.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    As permitted by the Oklahoma General Corporation Act under which the Company
is incorporated, Article X of the Company's Amended Certificate of Incorporation
provides for indemnification of each of the Company's officers and directors
against (a) expenses, including attorney's fees, judgments, fines and amounts
paid in settlement actually and reasonably incurred by him in connection with
any action, suit or proceeding brought by reason of his being or having been a
director, officer, employee or agent of the Company, or of any other
corporation, partnership, joint venture, or other enterprise at the request of
the Company, other than an action by or in the right of the Company, provided
that he acted in good faith and in a manner he reasonably believed to be in the
best interest of the Company, and with respect to any criminal action, he had no
reasonable cause to believe that his conduct was unlawful and (b) expenses
(including attorney's fees) actually and reasonably incurred by him in
connection with the defense or settlement of any action or suit by or in the
right of the Company brought by reason of his being or having been a director,
officer, employee or agent of the Company, or any other corporation,
partnership, joint venture, or other enterprise at the request of the Company,
provided that he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interest of the Company; except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged liable to the Company, unless and
only to the extent that the court in which such action or suit was decided has
determined that the person is fairly and reasonably entitled to indemnification
for such expenses which the court shall deem proper. The Company's bylaws
provide for similar indemnification. These provisions may be sufficiently broad
to indemnify such persons for liabilities arising under the Securities Act of
1933, as amended.
 
    The Company's directors and officers are also insured against claims arising
out of the performance of their duties in such capacities.

ITEM 22. UNDERTAKINGS.
 
    The undersigned Registrant hereby undertakes:
 
                                      II-3
<PAGE>
        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this Registration Statement:
 
            (i) To include any prospectus required by section 10(a)(3) of the
       Securities Act of 1933;
 
            (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the Registration Statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the Registration Statement;
 
           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in the Registration Statement or
       any material change to such information in the Registration Statement.
 
        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at the time shall be deemed to
    be the initial bona fide offering thereof.
 
        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
    The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.
 
    The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registration pursuant to the provisions described under Item 20, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnifications against public policy as expressed in
the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                          CERTIFICATE OF INCORPORATION
                                       OF
                           FRONT NINE HOLDINGS, INC. 


     FIRST:  The name of the corporation is FRONT NINE HOLDINGS, INC.. 

     SECOND:  The address of the corporation's registered office in the State 
of Oklahoma is 13439 North Broadway Extension, Oklahoma City, Oklahoma, 
73114.  The name of the corporation's registered agent at such address is 
Everett R. Dobson.

     THIRD:  The purpose of the corporation is to engage in any lawful act or 
activity for which corporations may be organized under the general 
corporation law of the State of Oklahoma.

     FOURTH:  The total number of shares of stock which the corporation shall 
have authority to issue is 500 shares, with a par value of $1.00 per share, 
all of which shall be Common Stock.

     The Board of Directors of the corporation shall have full authority, to 
the extent permitted by law, to increase, decrease or otherwise adjust the 
capital stock of the corporation, to designate the classes or series thereof 
and to determine whether all or any part of such stock shall have voting 
powers, full or limited, or no voting powers, and to determine such 
designations, and such powers, preferences, relative, participating or 
optional, or other special rights and the qualifications, limitations or 
restrictions thereof as the Board shall from time to time determine in duly 
adopted resolutions.

     At any time and from time to time when authorized by resolution of the 
Board of Directors and without any action by its shareholders, the 
corporation may issue or sell any shares of its capital stock of any class or 
series, whether out of the unissued shares thereof authorized by the 
Certificate of Incorporation of the corporation as originally filed or by an 
amendment thereof or out of shares of its capital stock acquired by it after 
the issue thereof, and whether or not the shares thereof so issued or sold 
shall confer upon the holders thereof the right to exchange or convert such 
shares for or into other classes or any series thereof.  When similarly 
authorized, but without any action by its shareholders, the corporation may 
issue or grant rights, warrants or options, in bearer or registered or such 
other form as the Board of Directors may determine, for the purchase of 
shares of the capital stock of any class or series of the corporation within 
such period of time, or without limit as to time, to such aggregate number of 
shares, and at such price per share, as the board of Directors may determine. 
Such rights, warrants or options may be issued or granted separately or in 
connection with the issue of any bonds, debentures, notes, obligations or 
other evidences of indebtedness or shares of the capital stock of any class 
or series of the corporation and for such consideration and 

<PAGE>

on such terms and conditions as the Board of Directors in its sole discretion 
may determine.  In each case, the consideration to be received by the 
corporation for any such shares so issued or sold shall be such as shall be 
fixed from time to time by resolution of the Board of Directors.

     FIFTH:  The name and mailing address of the incorporator is as follows:

                                   Oklahoma City, OK  73102
</TABLE>

     SIXTH:  In furtherance and not in limitation of the powers conferred by 
statute, the Board of Directors is expressly authorized:

          (a)  To adopt, amend or repeal the Bylaws of the corporation;

          (b)  To authorize and cause to be executed or granted mortgages,
     security interests and liens upon the real and personal property of the
     corporation;

          (c)  To set apart out of any of the funds of the corporation available
     for dividends a reserve or reserves for any proper purpose and to abolish
     any such reserve in the manner in which it was created;

          (d)  By a majority of the whole Board of Directors, to designate one
     or more committees, each committee to consist of one (1) or more of the
     directors of the corporation.  The board may designate one (1) or more
     directors as alternate members of any committee, who may replace any absent
     or disqualified member at any meeting of the committee.  Any such
     committee, to the extent provided in the resolution or in the Bylaws of the
     corporation, shall have and may exercise the powers of the Board of
     Directors in the management of the business and affairs of the corporation,
     and may authorize the seal of the corporation to be affixed to all papers
     which may require it; provided, however, the Bylaws may provide that in the
     absence or disqualification of any member of such committee or committees,
     the member or members thereof present at any meeting and not disqualified
     from voting, whether or not he or they constitute a quorum, may unanimously
     appoint another member of the Board of Directors to act at the meeting in
     the place of any such absent or disqualified member; and

          (e)  When and as authorized by the affirmative vote of 

<PAGE>

     the holders of a majority of the stock issued and outstanding having 
     voting power given at a shareholders' meeting duly called upon such 
     notice as is required by law, or when authorized by the written consent 
     of the holders of a majority of the voting stock issued and outstanding, 
     to sell, lease or exchange all or substantially all of the property and 
     assets of the corporation, including its goodwill and its corporate 
     franchises, upon such terms and conditions and for such consideration, 
     which may consist in whole or in part of other securities of, any other 
     corporation or corporations, as its Board of Directors shall deem 
     expedient and for the best interests of the corporation.

     SEVENTH:  Whenever a compromise or arrangement is proposed between this 
corporation and its creditors or any class of them and/or between this 
corporation and its shareholders or any class of them, any court of equitable 
jurisdiction within the State of Oklahoma, on the application in a summary 
way of this corporation or of any creditor or shareholder thereof, or on the 
application of any receiver or receivers appointed for this corporation under 
the provisions of Section 1106 of Title 18 of the Oklahoma Statutes or on the 
application of trustees in dissolution or of any receiver or receivers 
appointed for this corporation under the provisions of Section 1100 of Title 
18 of the Oklahoma Statutes order a meeting of the creditors or class of 
creditors, and/or of the shareholders or class of shareholders of this 
corporation, as the case may be, to be summoned in such manner as the court 
directs.  If a majority in number representing three-fourths (3/4ths) in 
value of the creditors or class of creditors, and/or of the shareholders or 
class of shareholders of this corporation, as the case may be, agree to any 
compromise or arrangement and to any reorganization of this corporation as 
consequence of such compromise or arrangement, the compromise or arrangement 
and the reorganization shall, if sanctioned by the court to which the 
application has been made, be binding on all the creditors or class of 
creditors and/or on all the shareholders or class of shareholders of this 
corporation, as the case may be, and also this corporation.

     EIGHTH:  Meetings of shareholders may be held within or out of the State 
of Oklahoma, as the Bylaws may provide.  The books of the corporation may be 
kept (subject to applicable law) inside or outside the State of Oklahoma at 
such place or places as may be designated from time to time by the Board of 
Directors or in the Bylaws of the corporation.  Elections of directors need 
not be by written ballot unless the Bylaws of the corporation shall so 
provide.

     NINTH:  To the extent permitted by law, no contract or transaction 
between the corporation and one or more of its directors or officers, or 
between the corporation and any other corporation, partnership, association 
or other organization in which one or more of its directors or officers are 
directors or officers or have a financial interest, shall be void or voidable 

<PAGE>

solely for this reason, or solely because the directors or officers are 
present at or participate in the meeting of the board or committee thereof 
which authorized the contract or transaction, or solely because the directors 
or officers or their votes are counted for such purpose.

     TENTH:  A director of the corporation shall not be personally liable to 
the corporation or its shareholders for damages for breach of fiduciary duty 
as a director, except for personal liability for (i) acts or omissions by 
such director not in good faith or which involve intentional misconduct or a 
knowing violation  of law; (ii) the payment of dividends or the redemption or 
purchase of stock in violation of Section 1041 or Section 1052 of the Act; 
(iii) any breach of such director's duty of loyalty to the corporation or its 
shareholders; or (iv) any transaction from which such director derived an 
improper personal benefit. 

     The corporation shall indemnify any person who was or is a party or is 
threatened to be made a party to any threatened, pending or completed action, 
suit or proceeding, whether civil, criminal, administrative or investigative 
(other than an action by or in the right of the corporation) by reason of the 
fact that he is or was a director, officer, employee or agent of the 
corporation, or is or was serving at the request of the corporation as a 
director, officer, employee or agent of another corporation, partnership, 
joint venture, or other enterprise, against expenses (including attorneys' 
fees), judgments, fines, and amounts paid in settlement actually and 
reasonably incurred by him in connection with such action, suit or 
proceeding, if he acted in good faith and in a manner he reasonably believed 
to be in the best interest of the corporation and, with respect to any 
criminal action or proceeding, had no reasonable cause to believe that his 
conduct was unlawful.  The termination of any action, suit or proceeding by 
judgment, order, settlement, conviction or upon a plea of nolo contendere or 
its equivalent shall not itself create a presumption that the person did not 
act in good faith and in a manner which he reasonably believed to be in, or 
not opposed to, the best interests of the corporation and with respect to any 
criminal action or proceeding had reasonable cause to believe that his 
conduct was unlawful. 

     The corporation shall indemnify any person who was or is a party or is 
threatened to be made a party to any threatened, pending or completed action 
or suit by or in the right of the corporation to procure a judgment in its 
favor by reason of the fact that he is or was a director, officer, employee 
or agent of the corporation or is or was serving at the request of the 
corporation as a director, officer, employee or agent of another corporation, 
partnership, joint venture, trust or other enterprise against expenses 
(including attorney's fees) actually and reasonably incurred by him in 
connection with the defense or settlement of such action or suit, if he acted 
in good faith and in a manner he reasonably believed to be in or not opposed 
to the best interest of the corporation; except that no indemnification 

<PAGE>

shall be made in respect of any claim, issue or matter as to which such 
person shall have been adjudged to be liable to the corporation unless and 
only to the extent that the court in which such action or suit was brought 
shall determine, upon application, that despite the adjudication of 
liability, but in the view of all the circumstances of the case, such person 
is fairly and reasonably entitled to indemnity for such expenses which the 
court shall deem proper.    

     Expenses, including fees and expenses of counsel, incurred in defending 
a civil, criminal, administrative or investigative action, suit or proceeding 
may be paid by the corporation in advance of the final disposition of such 
action, suit or proceeding upon receipt of an undertaking by or on behalf of 
the director, officer, employee or agent to repay such amount if it shall 
ultimately be determined that he is not entitled to be indemnified by the 
corporation as authorized herein.

     The corporation may purchase (upon resolution duly adopted by the Board 
of Directors) and maintain insurance on behalf of any person who is or was a 
director, officer, employee or agent of the corporation, or is or was serving 
at the request of the corporation as a director, officer, employee or agent 
of another corporation, partnership, joint venture, trust or other enterprise 
against any liability asserted against any liability asserted against him and 
incurred by him in any such capacity, or arising out of his status as such, 
whether or not the corporation would have the power to indemnify him against 
such liability.

     To the extent that a director, officer, employee or agent of, or any 
other person entitled to indemnity hereunder by, the corporation has been 
successful on the merits or otherwise in defense of any action, suit, or 
proceeding referred to herein or in defense of any claim, issue or matter 
therein, he shall be indemnified against expenses (including attorney's  
fees) actually and reasonably incurred by him in connection therewith.

     Every such person shall be entitled, without demand by him upon the 
corporation or any action by the corporation, to enforce his right to such 
indemnity in an action at law against the corporation.  The right of 
indemnification and advancement of expenses hereinabove provided shall not be 
deemed exclusive of any rights to which any such person may now or hereafter 
be otherwise entitled and specifically, without limiting the generality of 
the foregoing, shall not be deemed exclusive of any rights pursuant to 
statute or otherwise, of any such person in any such action, suit or 
proceeding to have assessed or allowed in his favor against the corporation 
or otherwise, his costs and expenses incurred therein or in connection 
therewith or any part thereof. 

     ELEVENTH:  In furtherance and not in limitation of the powers conferred 
by the laws of the State of Oklahoma, the Board of Directors is expressly 
authorized to adopt, amend or repeal the 

<PAGE>

Bylaws of the corporation.

     TWELFTH:  The corporation reserves the right to amend, alter, change or 
repeal any provision contained in this Certificate of Incorporation, in the 
manner now or hereafter prescribed by law, and all rights conferred upon the 
shareholders herein are granted subject to this reservation.

     THE UNDERSIGNED, being the incorporator hereinbefore named, for the 
purpose of forming a corporation pursuant to the Oklahoma General Corporation 
Act, make this Certificate, hereby declaring and certifying that this is the 
act and deed of the undersigned and that the facts herein stated are true, as

                                     -2-
<PAGE>

following (hereinafter collectively referred to as the "COLLATERAL"), whether 
characterized as investment property, general intangibles or otherwise:  (a) 
the Collateral Account, all funds held therein and all certificates and 
instruments, if any, from time to time representing or evidencing the 
Collateral Account, and all Collateral Investments (as hereinafter defined) 
and all certificates and instruments, if any, representing or evidencing the 
Collateral Investments, and any and all security entitlements to the 
Collateral Investments, and any and all related securities accounts in which 
security entitlements to the Collateral Investments are carried, (b) all 
notes, certificates of deposit, deposit accounts, checks and other 
instruments from time to time hereafter delivered to or otherwise possessed 
by the Trustee for or on behalf of the Pledgor in substitution for or in 
addition to any or all the then existing Collateral, (c) all interest, 
dividends, cash, instruments and other property from time to time received, 
receivable or otherwise distributed in respect of or in exchange for any or 
all of the then existing Collateral, and (d) all proceeds of any and all of 
the foregoing Collateral (including, without limitation, proceeds that 
constitute property of the types described in clauses (a) - (d) of this 
Section 1) and, to the extent not otherwise included, all cash.

            1.4   DEPOSIT OF FUNDS.  On the Closing Date, the Pledgor shall
direct that the Funds be deposited into the Collateral Account.

the grant of a security interest in the Collateral hereunder secures the prompt
payment and performance when due (whether at stated maturity, by acceleration or
otherwise) of all the Obligations.  Without limiting the generality of the
foregoing, this Pledge Agreement and the grant of a security interest in the
Collateral hereunder secures the payment of all amounts that constitute part of
the Obligations and would be owed by the Pledgor to the Trustee or the Holders
under the Notes or the Indenture but for the fact that they are unenforceable or
not allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving the Pledgor.

            SECTION 3.  DELIVERY OF COLLATERAL.  (a)  All certificates or
instruments representing or evidencing the Collateral, including, without
limitation, amounts invested as provided in Section 5, shall be delivered to (as
set forth in Section 6) and held by or on behalf of the Trustee pursuant hereto
and shall be in suitable form for transfer by delivery, or shall be accompanied
by duly executed instruments of transfer or assignment in blank, all in form and
substance sufficient to establish and maintain in favor of the Trustee a valid
security interest in such Collateral, and shall be credited to the Collateral
Account.  In addition, the Trustee shall have the right at any time to exchange
certificates or instruments representing or evidencing the Collateral for
certificates or instruments of smaller or larger denominations.

            (b)   Concurrently with the execution and delivery of this Pledge
     Agreement, the Trustee is delivering to the Pledgor and NationsBanc
     Montgomery Securities LLC a duly executed Notification and Control
     Agreement ("CONTROL AGREEMENT"), substantially in the form of EXHIBIT A
     hereto, confirming the Trustee's establishment and separate maintenance of
     the Collateral Account, all in accordance with this Pledge Agreement.


                                     -3-
<PAGE>

            SECTION 4.  MAINTAINING THE COLLATERAL ACCOUNT.  (a)  So long as any
Obligation shall remain unpaid, the Trustee will maintain separately the
Collateral Account with United States Trust Company of New York, which account
shall at all times be under the sole dominion and control of the Trustee and
subject to the terms and conditions of this Pledge Agreement.

            (b)    It shall be a term and condition of the Collateral Account,
     notwithstanding any term or condition to the contrary in any other
     agreement relating to the Collateral Account, and except as otherwise
     provided by the provisions of Section 7 and Section 14 hereof, that no
     amount (including interest on Collateral Investments) shall be paid or
     released to or for the account of, or withdrawn by or for the account of,
     the Pledgor or any other Person from the Collateral Account.

            The Collateral Account shall be subject to such applicable laws, and
such applicable regulations of the Board of Governors of the Federal Reserve
System and of any other appropriate banking or governmental authority, as may
now or hereafter be in effect.

            SECTION 5.  INVESTING OF AMOUNTS IN THE COLLATERAL ACCOUNT.  If
directed by the Pledgor in writing, the Trustee will, subject to the provisions
of Section 7 and Section 14 hereof, from time to time (a) invest amounts on
deposit in the Collateral Account in such Cash Equivalents, each in the name of
or for the account of the Trustee, as the Pledgor may select and the Trustee may
approve and (b) invest interest paid on the Cash Equivalents referred to in
clause (a) above, and reinvest other proceeds of any such Cash Equivalents that
may mature or be sold, in each case in such Cash Equivalents, each in the name
of or for the account of the Trustee, as the Pledgor may select and the Trustee
may approve (the Cash Equivalents referred to in clauses (a) and (b) above being
collectively "COLLATERAL INVESTMENTS").  The amount on deposit in the Collateral
Account must include Government Securities sufficient, in the opinion of a
nationally recognized firm of independent public accountants selected by the
Pledgor, to provide for the payment in full of the first six scheduled interest
payments on all of the Notes then outstanding.  Interest and proceeds that are
not invested or reinvested in Collateral Investments as provided above shall be
deposited and held in the Collateral Account.  The Trustee shall in no event be
liable for any loss in the investment or reinvestment of amounts held in the
Collateral Account.

            SECTION 6.  DELIVERY OF COLLATERAL INVESTMENTS.  (a)  The Trustee
shall become the holder of the Collateral Investments (and any applicable
security entitlements thereto) through the following delivery procedures: 
(i) in the case of Collateral Investments which are certificated securities in
registered form, delivery of the applicable certificate(s), specially endorsed
to the Trustee or registered in the name of the Trustee or accompanied by duly
executed instruments of transfer or assignment in blank, all in form and
substance satisfactory to the Trustee, to the possession of (A) the Trustee,
(B) a securities intermediary or financial intermediary acting on behalf of the
Trustee, or (C) another person, other than a securities intermediary or
financial intermediary, which person acknowledges that it holds for the Trustee;
(ii) in the case of Collateral 


                                     -4-
<PAGE>

Investments which are uncertificated securities, registration of one of the 
following as owner of such uncertificated securities: the Trustee or a person 
designated by the Trustee, or person other than a securities intermediary or 
financial intermediary, that becomes the registered owner of such 
uncertificated securities and acknowledges that it holds the same for the 
Trustee; and (iii) in the case of Collateral Investments in the form of 
Government Book-Entry Securities, the making by a financial intermediary or 
securities intermediary (other than a clearing corporation) to whose account 
such Government Book-Entry Securities have been credited on the books of a 
Federal Reserve Bank (or on the books of another such financial intermediary 
or securities intermediary (other than a clearing corporation)), of book 
entries indicating that such Government Book-Entry Securities have been 
credited to an account of the Trustee, and the sending by such financial 
intermediary or securities intermediary to the Trustee of confirmation of 
such transfer to the Trustee's account.  

            (b)    Upon delivery of any Collateral Investments to the Trustee
     (or the Trustee's acquisition of a security entitlement thereto), the
     Trustee shall make appropriate book entries indicating that such Collateral
     Investment and/or such security entitlement has been credited to and is
     held in the Collateral Account.  Subject to the terms and conditions of
     this Pledge Agreement, all Collateral Investments held by the Trustee
     pursuant to this Pledge Agreement shall be held in the Collateral Account
     under the exclusive dominion and control of the Trustee and for the benefit
     of the Trustee and the ratable benefit of the Holders of the Notes and
     segregated from all other funds or other property otherwise held by the
     Trustee.

            SECTION 7.  DISBURSEMENTS.  The Trustee shall hold the assets in
the Collateral Account and release the same, or a portion thereof, only as
follows:

            (a)   At least three Business Days prior to the due date of any of
     the first six scheduled interest payments on the Notes, the Pledgor may,
     pursuant to written instructions executed by the Pledgor (an "ISSUER
     ORDER"), direct the Trustee to release from the Collateral Account, and if
     necessary liquidate Collateral Investments in the Collateral Account and
     pay to the Holders of the Notes funds sufficient to provide for payment in
     full of such interest then due on the Notes.  Upon receipt of an Issuer
     Order, the Trustee will take any action necessary to provide for the
     payment of the interest on the Notes in accordance with the payment
     provisions of the Indenture to the Holders of the Notes from (and to the
     extent of) funds available in the Collateral Account. 

            (b)   If the Pledgor makes any interest payment or portion of an
     interest payment for which the Collateral is security from a source of
     funds other than the Collateral Account ("PLEDGOR FUNDS"), the Pledgor may,
     after payment in full of such interest payment or portion thereof from
     proceeds of the Collateral or such Pledgor Funds or both, direct the
     Trustee to release to the Pledgor or to another party at the direction of
     the Pledgor (a "PLEDGOR DESIGNEE") funds from the Collateral Account, and
     if necessary liquidate 


                                     -5-
<PAGE>

     Collateral Investments in the Collateral Account, in an amount less than 
     or equal to the amount of Pledgor Funds applied to such interest 
     payment.  Upon receipt of an Issuer Order by the Trustee, the Trustee 
     shall pay over to the Pledgor or the Pledgor's Designee, as the case may 
     be, the requested amount from funds in the Collateral Account. 
     Concurrently with any release of funds to the Pledgor pursuant to this 
     Section 7(b), the Pledgor shall deliver to the Trustee a certificate 
     signed by an officer of the Pledgor stating that such release has been 
     duly authorized by the Pledgor and will not contravene any provision of 
     applicable law or the Certificate of Incorporation of the Pledgor or any 
     material agreement or other material instrument binding upon the Pledgor 
     or any of its subsidiaries or any judgment, order or decree of any 
     governmental body, agency or court having jurisdiction over the Pledgor 
     or any of its subsidiaries or result in the creation or imposition of 
     any Lien on any assets of the Pledgor, except for the security interest 
     granted under this Pledge Agreement.

            (c)   Upon payment in full of the first six scheduled interest
     payments on the Notes, the security interest in the Collateral evidenced by
     this Pledge Agreement will automatically terminate and be of no further
     force and effect and the Collateral shall promptly be paid over and
     transferred to the Pledgor or a Pledgor Designee.  In addition, upon the
     release of any Collateral from the Collateral Account in accordance with
     the terms of this Pledge Agreement, the security interest evidenced by this
     Pledge Agreement in such released Collateral will automatically terminate
     and be of no further force and effect.

            (d)   The Trustee shall not be required to liquidate any Collateral
     Investment in order to make any payment hereunder unless instructed to do
     so pursuant to an Issuer Order or pursuant to Section 14 hereof.

            (e)   Nothing contained in Section 1, Section 5, Section 6, this
     Section 7 or any other provision of this Pledge Agreement shall (i) afford
     the Pledgor any right to issue entitlement orders with respect to any
     security entitlement to any of the Collateral Investments or any securities
     account in which any such security entitlement may be carried, or otherwise
     afford the Pledgor control of any such security entitlement or
     (ii) otherwise give rise to any rights of the Pledgor with respect to any
     of the Collateral Investments, any security entitlement thereto or any
     securities account in which any such security entitlement may be carried,
     other than the Pledgor's beneficial interest under this Pledge Agreement in
     collateral pledged to and subject to the exclusive dominion and control
     (consistent with this Pledge Agreement) of the Trustee in its capacity as
     such (and not as a securities intermediary).  The Pledgor acknowledges,
     confirms and agrees that the Trustee holds a security entitlement to the
     Collateral Investments solely as trustee for the Holders of the Notes and
     not as a securities intermediary or financial intermediary.

            (f)   Nothing in this Section 7 shall affect the Trustee's rights
     to apply the Collateral to the payments of amounts due on the Notes upon
     acceleration thereof.


                                     -6-

<PAGE>

            (g)    At least three Business Days prior to the due date of any of
     the first six scheduled interest payments on the Notes, the Pledgor
     covenants to give the Trustee (by Issuer Order) notice as to whether
     payment of interest will be made pursuant to Section 7(a) or Section 7(b)
     and as to the respective amounts of interest that will be paid pursuant to
     Section 7(a) or Section 7(b).  If no such notice is given, the Trustee will
     act pursuant to Section 7(a) as if it had received an Issuer Order pursuant
     thereto for the payment in full of the interest then due.

            SECTION 8.    REPRESENTATIONS AND WARRANTIES.  The Pledgor hereby 
represents and warrants that:

            (a)    The execution and delivery by the Pledgor of, and the
     performance by the Pledgor of its obligations under, this Pledge Agreement
     and the Control Agreement will not contravene any provision of applicable
     law or the certificate of incorporation or by-laws of the Pledgor, or any
     material agreement or other material instrument binding upon the Pledgor or
     any of its subsidiaries or any judgment, order or decree of any
     governmental body, agency or court having jurisdiction over the Pledgor or
     any of its subsidiaries, or result in the creation or imposition of any
     Lien on any assets of the Pledgor, except for the security interests
     granted under this Pledge Agreement.

            (b)    No consent of any other person and no approval,
     authorization, order of, or filing, declaration or qualification with, any
     governmental body or agency is required (i) for the execution, delivery or
     performance by the Pledgor of its obligations under either this Pledge
     Agreement or the Control Agreement, (ii) for the grant by the Pledgor of
     the security interest created hereby or (ii) for the pledge by the Pledgor
     of the Collateral pursuant to either this Pledge Agreement or the Control
     Agreement, except for any such consents, approvals, authorizations or
     orders required to be obtained by the Trustee (or the Holders) for reasons
     other than the consummation of this transaction, for the exercise by the
     Trustee of the rights provided for in either this Pledge Agreement or the
     Control Agreement or the remedies in respect of the Collateral pursuant to
     either this Pledge Agreement or the Control Agreement.

            (c)    The Pledgor is the beneficial owner of the Collateral, free
     and clear of any Lien or claims of any person or entity (except for the
     security interests created by this Pledge Agreement).  No financing
     statement or instrument similar in effect covering all or any part of the
     Pledgor's interest in the Collateral is on file in any public or recording
     office, other than the financing statements filed pursuant to this Pledge
     Agreement.  The Pledgor has no trade names.

            (d)    This Pledge Agreement has been duly authorized, validly
     executed and delivered by the Pledgor and constitutes a valid and binding
     agreement of the Pledgor, enforceable against the Pledgor in accordance
     with its terms, except as (i) the enforceability 

                                      -7-
<PAGE>

     hereof may be limited by bankruptcy, insolvency or similar laws affecting 
     creditors' rights generally, (ii) the availability of equitable remedies 
     may be limited by equitable principles of general applicability, (iii) the
     exculpation provisions and rights to indemnification hereunder may be 
     limited by U.S. federal and state securities laws and public policy 
     considerations and (iv) the waiver of rights and defenses contained in 
     Section 14(d), Section 17.11 and Section 17.15 hereof may be limited by 
     applicable law.

            (e)    Upon the transfer to the Trustee of the Funds and the
     acquisition by the Trustee of a security entitlement thereto, in accordance
     with Section 3 above, the pledge and grant of a security interest in the
     Collateral pursuant to this Pledge Agreement for the benefit of the Trustee
     and the Holders of the Notes will constitute a valid and perfected first
     priority security interest in such Collateral, securing the payment of the
     Obligations enforceable as such against all creditors of the Pledgor (and
     any persons purporting to purchase any of the Collateral from the Pledgor).

            (f)    There are no legal or governmental proceedings pending or, to
     the best of the Pledgor's knowledge, threatened to which the Pledgor or any
     of its subsidiaries is a party or to which any of the properties of the
     Pledgor or any such subsidiary is subject that would materially adversely
     affect the power or ability of the Pledgor to perform its obligations under
     this Pledge Agreement or to consummate the transactions contemplated
     hereby.

            (g)    The pledge of the Collateral pursuant to this Pledge
     Agreement is not prohibited by law or governmental regulation (including,
     without limitation, Regulations T, U and X of the Board of Governors of the
     Federal Reserve System) applicable to the Pledgor.

            (h)    No Event of Default (as defined herein) exists.

            SECTION 9.    FILING; FURTHER ASSURANCES.  (a)  Concurrently with 
the execution and delivery of this Pledge Agreement, the Pledgor is 
delivering to the Trustee acknowledgment copies or stamped receipt copies of 
proper financing statements, duly filed on or before the Closing Date in 
accordance with the Uniform Commercial Code as in effect in the State of New 
York and the State of Oklahoma, covering the categories of Collateral 
described in this Pledge Agreement.

            (b)    The Pledgor agrees that from time to time, at the expense of
     the Pledgor, the Pledgor will, promptly upon request by the Trustee (which
     request the Trustee may submit at the direction of the holders of a
     majority in principal amount of the Notes then outstanding), execute and
     deliver or cause to be executed and delivered, or use its reasonable best
     efforts to procure, all assignments, instruments and other documents, all
     in form and substance satisfactory to the Trustee, deliver any instruments
     to the Trustee and take any other actions that may be necessary or, in the
     opinion of the Trustee, desirable to perfect, continue the perfection of,
     or protect the first priority of the Trustee's security 

                                      -8-

     interest in and to the Collateral, including the filing of all necessary 
     financing and continuation statements, to protect the Collateral against 
     the rights, claims, or interests of third persons (other than any such 
     rights, claims or interests created by or arising through the Trustee) or 
     to effect the purposes of this Pledge Agreement. 

            (c)    The Pledgor hereby authorizes the Trustee to file any
     financing or continuation statements in the United States with respect to
     the Collateral without the signature of the Pledgor (to the extent
     permitted by applicable law). A photocopy or other reproduction of this
     Pledge Agreement or any financing statement covering the Collateral or any
     part thereof shall be sufficient as a financing statement where permitted
     by law.

            (d)    The Pledgor will promptly pay all costs incurred in
     connection with this Pledge Agreement within 45 days of receipt of an
     invoice therefor. 

            SECTION 10.  COVENANTS.  The Pledgor covenants and agrees with 
the Trustee and the Holders of the Notes that from and after the date of this 
Pledge Agreement until payment in full of all of the Obligations:  

            (a)    that (i) it will not (and will not purport to) sell or
     otherwise dispose of, or grant any option or warrant with respect to, any
     of the Collateral or its beneficial interest therein, and (ii) it will not
     create or permit to exist any Lien or other adverse interest in or with
     respect to its beneficial interest in any of the Collateral (except for the
     security interests granted under this Pledge Agreement); and

            (b)    that it will not (i) enter into any agreement or
     understanding that restricts or inhibits or purports to restrict or inhibit
     the Trustee's rights or remedies hereunder, including, without limitation,
     the Trustee's right to sell or otherwise dispose of the Collateral or (ii)
     fail to pay or discharge any tax, assessment or levy of any nature with
     respect to its beneficial interest in the Collateral not later than five
     days prior to the date of any proposed sale under any judgment, writ or
     warrant of attachment with respect to such beneficial interest.

            SECTION 11.  POWER OF ATTORNEY.    In addition to all of the 
powers granted to the Trustee pursuant to the Indenture, the Pledgor hereby 
appoints and constitutes the Trustee as the Pledgor's attorney-in-fact (with 
full power of substitution), with full authority in the place and stead of 
the Pledgor and in the name of the Pledgor or otherwise, from time to time in 
the Trustee's discretion to take any action and to execute any instrument 
that the Trustee may deem necessary or advisable to accomplish the purposes 
of this Pledge Agreement, including, without limitation:

            (a)    to ask for, demand, collect, sue for, recover, compromise,
     receive and give acquittance and receipts for moneys due and to become due
     under or in respect of any of the Collateral,

                                      -9-
<PAGE>

            (b)    to receive, indorse and collect any drafts or other
     instruments, documents and chattel paper, in connection with clause (a)
     above,

            (c)    to file any claims or take any action or institute any
     proceedings that the Trustee may deem necessary or desirable for the
     collection of any of the Collateral or otherwise to enforce the rights of
     the Trustee with respect to any of the Collateral,

            (d)    to pay or discharge taxes or Liens levied or placed upon the
     Collateral, the legality or validity thereof and the amounts necessary to
     discharge the same to be determined by the Trustee in its sole reasonable
     discretion, and such payments made by the Trustee to become part of the
     Obligations of the Pledgor to the Trustee, due and payable immediately upon
     demand, and

            (e)    to convey any item of Collateral to any purchaser thereof and
     give any notices or recordings of any Liens under Section 6 hereof;

PROVIDED, HOWEVER, that the Trustee shall have no obligation to perform any 
of the foregoing actions.  The Trustee's authority under this Section 11 
shall include, without limitation, the authority to execute or endorse (a) 
any checks or instruments representing proceeds of Collateral in the name of 
the Pledgor, (b) any receipts for any certificate of ownership or any 
document constituting Collateral or transferring title to any item of 
Collateral, (c) any financing statements (to the extent permitted by 
applicable law) or (d) any other documents deemed necessary or appropriate by 
the Trustee to preserve, protect or perfect the security interest in the 
Collateral and to file the same, prepare, file and sign the Pledgor's name on 
any notice of Lien, and to take any other actions arising from or incident to 
the powers granted to the Trustee in this Pledge Agreement.  This power of 
attorney is coupled with an interest and is irrevocable by the Pledgor.

            SECTION 12.  NO ASSUMPTION OF DUTIES; REASONABLE CARE.  The 
rights and powers conferred on the Trustee hereunder are solely to preserve 
and protect the security interest of the Trustee and the Holders of the Notes 
in and to the Collateral granted hereby and shall not be interpreted to, and 
shall not impose any duties on the Trustee in connection therewith other than 
those expressly provided herein or imposed under applicable law.  Except as 
provided by applicable law or by the Indenture, the Trustee shall be deemed 
to have exercised reasonable care in the custody and preservation of the 
Collateral in its possession if the Collateral is accorded treatment 
substantially equal to that which the Trustee accords similar property held 
by the Trustee for its own account, it being understood that the Trustee in 
its capacity as such shall not have any responsibility for (a) ascertaining 
or taking action with respect to calls, conversions, exchanges, maturities or 
other matters relative to any Collateral, whether or not the Trustee has or 
is deemed to have knowledge of such matters, (b) taking any necessary steps 
to preserve rights against any parties with respect to any Collateral or (c) 
investing or reinvesting any of the Collateral or any loss on any investment.

            SECTION 13.  INDEMNITY; TRUSTEE'S LIMITATION OF LIABILITY TO 
PLEDGOR.  (a)  The Pledgor shall indemnify, reimburse, hold harmless and 
defend the Trustee and its directors, officers, agents and employees, from 
and against any and all claims, actions, obligations, liabilities and 
expenses, including reasonable defense costs, reasonable investigative fees 
and costs, and reasonable legal fees and damages arising from the Trustee's 
performance or lack of performance as Trustee under this Pledge Agreement, 
except to the extent that such claim, action, obligation, liability or 
expense is directly attributable to the bad faith, gross negligence or wilful 
misconduct of such indemnified person. This indemnity shall be a continuing 
obligation of the Pledgor, its respective successors and assigns, 
notwithstanding the termination of this Pledge Agreement.

            (b)    If at any time the Trustee is served with any judicial or
     administrative order, judgment, decree, writ or other form of judicial or
     administrative process which in any way affects Collateral (including, but
     not limited to, orders of attachment or garnishment or other forms of
     levies or injunctions or stays relating to the transfer of Collateral), the
     Trustee is authorized to comply therewith in any manner as it or its legal
     counsel of its own choosing deems appropriate and if the Trustee complies
     with any such judicial or administrative order, judgment, decree, writ or
     other form of judicial or administrative process, the Trustee shall not be
     liable to the Pledgor even though such order, judgment, decree, writ or
     process may be subsequently modified or vacated or otherwise determined to
     have been without legal force or effect.

            (c)    The Trustee shall not incur any liability to the Pledgor for
     not performing any act or fulfilling any duty, obligation or responsibility
     hereunder by reason of any occurrence beyond the control of the Trustee
     (including, but not limited to, any act or provision or any present or
     future law or regulation or governmental authority, any act of God or war,
     or the unavailability of the Federal Reserve Bank wire or telex or other
     wire or communication facility).

            (d)    The Trustee shall not be responsible in any respect for the
     form, execution, validity, value or genuineness of documents or securities
     deposited hereunder, or for any description therein, or for the identity,
     authority or rights of persons executing or delivering or purporting to
     execute or deliver any such document, security or endorsement.

            SECTION 14.  REMEDIES UPON EVENT OF DEFAULT.  If any Event of 
Default under the Indenture or default hereunder (any such Event of Default 
or default being referred to in this Pledge Agreement as an "EVENT OF 
DEFAULT") shall have occurred and be continuing:

            (a)    The Trustee and the Holders of the Notes may exercise, in
     addition to all other rights given by law or by this Pledge Agreement or
     the Indenture, all of the rights and remedies with respect to the
     Collateral of a secured party under the UCC in effect in the State of New
     York at that time and also may (i) require the Pledgor to, and the Pledgor
     hereby agrees that it will at its expense and upon request of the Trustee
     forthwith, assemble 

                                      -11-
<PAGE>

     all or part of the Collateral as directed by the Trustee and make it 
     available to the Trustee at a place to be designated by the Trustee that 
     is reasonably convenient to both parties and (ii) without notice except 
     as specified below, sell the Collateral or any part thereof in one or 
     more parcels at any broker's board or at public or private sale, in one 
     or more sales or lots, at any of the Trustee's offices or elsewhere,
     for cash, on credit or for future delivery, and upon such other terms as
     the Trustee may deem commercially reasonable.  The Pledgor agrees that, to
     the extent notice of sale shall be required by law, at least ten days'
     notice to the Pledgor of the time and place of any public sale or the time
     after which any private sale is to be made shall constitute reasonable
     notification.  The Trustee shall not be obligated to make any sale of
     Collateral regardless of notice of sale having been given.  The Trustee may
     adjourn any public or private sale from time to time by announcement at the
     time and place fixed therefor, and such sale may, without further notice,
     be made at the time and place to which it was so adjourned.  The purchaser
     of any or all Collateral so sold shall thereafter hold the same absolutely,
     free from any claim, encumbrance or right of any kind whatsoever created by
     or through the Pledgor.  Any sale of the Collateral conducted in conformity
     with reasonable commercial practices of banks, insurance companies,
     commercial finance companies, or other financial institutions disposing of
     property similar to the Collateral shall be deemed to be commercially
     reasonable.  The Trustee or any Holder of Notes may, in its own name or in
     the name of a designee or nominee, buy any of the Collateral at any public
     sale and, if permitted by applicable law, at any private sale.  All
     expenses (including court costs and reasonable attorneys' fees, expenses
     and disbursements) of, or incident to, the enforcement of any of the
     provisions hereof shall be recoverable from the proceeds of the sale or
     other disposition of the Collateral.

            (b)    All cash proceeds received by the Trustee in respect of any
     sale of, collection from, or other realization upon all or any part of the
     Collateral may, in the discretion of the Trustee, be held by the Trustee as
     collateral for, and/or then or at any time thereafter applied (after
     payment of any amounts payable to the Trustee pursuant to Section 15) in
     whole or in part by the Trustee for the ratable benefit of the Holders of
     the Notes against, all or any part of the Obligations in such order as the
     Trustee shall elect or the Holders of at least 25% in aggregate principal
     amount of the Notes then outstanding shall request.  Any surplus of such
     cash or cash proceeds held by the Trustee and remaining after payment in
     full of all the Obligations shall be paid over to the Pledgor or to
     whomsoever may be lawfully entitled to receive such surplus.

            (c)    The Pledgor further agrees to use its reasonable best efforts
     to do or cause to be done all such other acts as may be necessary to make
     such sale or sales of all or any portion of the Collateral pursuant to this
     Section 14 valid and binding and in compliance with any and all other
     applicable requirements of law.  The Pledgor further agrees that a breach
     of any of the covenants contained in this Section 14 will cause irreparable
     injury to the Trustee and the Holders of the Notes, that the Trustee and
     the Holders of the Notes have no adequate remedy at law in respect of such
     breach and, as a consequence, that each and 

                                      -12-
<PAGE>

     every covenant contained in this Section 14 shall be specifically 
     enforceable against the Pledgor, and the Pledgor hereby waives and agrees 
     not to assert any defenses against an action for specific performance of 
     such covenants except for a defense that no Event of Default has occurred.

            SECTION 15.  EXPENSES.  The Pledgor will upon demand pay to the 
Trustee the amount of any and all reasonable expenses, including, without 
limitation, the reasonable fees, expenses and disbursements of its counsel, 
experts and agents retained by the Trustee, that the Trustee may incur in 
connection with (a) the review, negotiation and administration of this Pledge 
Agreement, (b) the custody or preservation of, or the sale of, collection 
from, or other realization upon, any of the Collateral, (c) the exercise or 
enforcement of any of the rights of the Trustee and the Holders of the Notes 
hereunder or (d) the failure by the Pledgor to perform or observe any of the 
provisions hereof.

            SECTION 16.  SECURITY INTEREST ABSOLUTE.  All rights of the 
Trustee and the Holders of the Notes and security interests hereunder, and 
all obligations of the Pledgor hereunder, shall be absolute and unconditional 
irrespective of:

            (a)    any lack of validity or enforceability of the Indenture or
     Notes or any other agreement or instrument relating thereto;

            (b)    any change in the time, manner or place of payment of, or in
     any other term of, all or any of the Obligations, or any other amendment or
     waiver of or any consent to any departure from the Indenture;

            (c)    any taking, exchange, surrender, release or non-perfection of
     any Liens on any other collateral for all or any of the Obligations; 

            (d)    any manner of application of collateral, or proceeds thereof,
     to all or any of the Obligations, or any manner of sale or other
     disposition of any collateral for all or any of the Obligations or any
     other assets of the Pledgor;

            (e)    any change, restructuring or termination of the corporate
     structure or existence of the Pledgor; or

            (f)    to the extent permitted by applicable law, any other
     circumstance which might otherwise constitute a defense available to, or a
     discharge of, the Pledgor in respect of the Obligations or of this Pledge
     Agreement.

            Section 17.2.  NO ADVERSE INTERPRETATION OF OTHER AGREEMENTS.  
This Pledge Agreement may not be used to interpret another pledge, security 
or debt agreement of the Pledgor or any subsidiary thereof.  No such pledge, 
security or debt agreement (other than the Indenture) may be used to 
interpret this Pledge Agreement.

            Section 17.3.  SEVERABILITY.  The provisions of this Pledge 
Agreement are severable, and if any clause or provision shall be held 
invalid, illegal or unenforceable in whole or in part in any jurisdiction, 
then such invalidity or unenforceability shall affect in that jurisdiction 
only such clause or provision, or part thereof, and shall not in any manner 
affect such clause or provision in any other jurisdiction or any other clause 
or provision of this Pledge Agreement in any jurisdiction.

            Section 17.4.  HEADINGS.  The headings in this Pledge Agreement 
have been inserted for convenience of reference only, are not to be 
considered a part hereof and shall in no way modify or restrict any of the

            Section 17.5.  COUNTERPART ORIGINALS.  This Pledge Agreement may 
be signed in two or more counterparts, each of which shall be deemed an 
original, but all of which shall together constitute one and the same 
agreement.

            Section 17.6.  BENEFITS OF PLEDGE AGREEMENT.  Nothing in this 
Pledge Agreement, express or implied, shall give to any person, other than 
the parties hereto and their successors hereunder, and the Holders of the 
Notes, any benefit or any legal or equitable right, remedy or claim under 
this Pledge Agreement.

            Section 17.7.  AMENDMENTS, WAIVERS AND CONSENTS.  Any amendment 
or waiver of any provision of this Pledge Agreement and any consent to any 
departure by the Pledgor from any provision of this Pledge Agreement shall be 
effective only if made or duly given in compliance with all of the terms and 
provisions of the Indenture, and then such waiver or consent shall be 
effective only in the specific instance and for the specific purpose for 
which given.  Neither the Trustee nor any Holder of Notes shall be deemed, by 
any act, delay, indulgence, omission or otherwise, to have waived any right 
or remedy hereunder or to have acquiesced in any Default or Event of Default 
or in any breach of any of the terms and conditions hereof.  Failure of the 
Trustee or any Holder of Notes to exercise, or delay in exercising, any 
right, power or privilege hereunder shall not preclude any other or further 
exercise thereof or the exercise of any other right, power or privilege.  A 
waiver by the Trustee or any Holder of Notes of any right or remedy hereunder 
on any one occasion shall not be construed as a bar to any right or remedy 
that the Trustee or such Holder of Notes would otherwise have on any future 
occasion.  The rights and remedies herein provided are cumulative, may be 
exercised singly or concurrently and are not exclusive of any rights or 
remedies provided by law.

            Section 17.8.  INTERPRETATION OF AGREEMENT.  As long as the 
Trustee acts in good faith to the extent a term or provision of this Pledge 
Agreement conflicts with the Indenture, the Indenture shall control with 
respect to the subject matter of such term or provision.  Notwithstanding the 
foregoing and any other provision of this Pledge Agreement or the Indenture, 
the Trustee shall have no fiduciary responsibility under this Pledge 
Agreement.

            Section 17.9.  CONTINUING SECURITY INTEREST; TERMINATION.  (a)  
This Pledge Agreement shall create a continuing security interest in and to 
the Collateral and shall, unless otherwise provided in this Pledge Agreement, 
remain in full force and effect until the payment in full in cash of the 
Obligations. This Pledge Agreement shall be binding upon the Pledgor, its 
transferees, successors and assigns, and shall inure, together with the 
rights and remedies of the Trustee hereunder, to the benefit of the Trustee, 
the Holders of the Notes and their respective successors, transferees and 
assigns.

            (b)    So long as no Event of Default shall have occurred and be 
continuing, this Pledge Agreement (other than Pledgor's obligations under 
Sections 13 and 15) shall terminate upon the payment in full in cash of the 
Obligations.  At such time, the Trustee shall, pursuant to an Issuer 

                                      -15-
<PAGE>

Order, reassign and redeliver to the Pledgor all of the Collateral hereunder 
that has not been sold, disposed of, retained or applied by the Trustee in 
accordance with the terms of this Pledge Agreement and the Indenture and take 
all actions requested by the Pledgor that are necessary to release the 
security interest created by this Pledge Agreement in and to the Collateral, 
including the execution and delivery of all termination statements necessary 
to terminate any financing or continuation statements filed with respect to 
the Collateral.  Such reassignment and redelivery shall be without warranty 
by or recourse to the Trustee in its capacity as such and shall be at the 
reasonable expense of the Pledgor.  

            Section 17.10.  SURVIVAL OF REPRESENTATIONS AND COVENANTS.  All 
representations, warranties and covenants of the Pledgor contained herein 
shall survive the execution and delivery of this Pledge Agreement, and shall 
terminate only upon the termination of this Pledge Agreement.  The 
obligations of the Pledgor under Sections 13 and 15 hereof shall survive the 
termination of this Agreement.

            Section 17.11.  WAIVERS.  The Pledgor waives presentment and 
demand for payment of any of the Obligations, protest and notice of dishonor 
or default with respect to any of the Obligations, and all other notices to 
which the Pledgor might otherwise be entitled, except as otherwise expressly 
provided herein or in the Indenture.

            Section 17.12.  AUTHORITY OF THE TRUSTEE.  (a)  The Trustee shall 
have and be entitled to exercise all powers hereunder that are specifically 
granted to the Trustee by the terms hereof, together with such powers as are 
reasonably incident thereto.  The Trustee may perform any of its duties 
hereunder or in connection with the Collateral by or through agents or 
employees and shall be entitled to retain counsel and to act in reliance upon 
the advice of counsel concerning all such matters.  Except as otherwise 
expressly provided in this Pledge Agreement or the Indenture, neither the 
Trustee nor any director, officer, employee, attorney or agent of the Trustee 
shall be liable to the Pledgor for any action taken or omitted to be taken by 
the Trustee, in its capacity as Trustee, hereunder, except for its own bad 
faith, gross negligence or willful misconduct, and the Trustee shall not be 
responsible for the validity, effectiveness or sufficiency hereof or of any 
document or security furnished pursuant hereto.  The Trustee and its 
directors, officers, employees, attorneys and agents shall be entitled to 
rely on any communication, instrument or document believed by it or them to 
be genuine and correct and to have been signed or sent by the proper person 
or persons.

            (b)    The Pledgor acknowledges that the rights and 
responsibilities of the Trustee under this Pledge Agreement with respect to 
any action taken by the Trustee or the exercise or non-exercise by the 
Trustee of any option, right, request, judgment or other right or remedy 
provided for herein or resulting or arising out of this Pledge Agreement 
shall, as between the Trustee and the Holders of the Notes, be governed by 
the Indenture and by such other agreements with respect thereto as may exist 
from time to time among them, but, as between the Trustee and the Pledgor, 
the Trustee shall be conclusively presumed to be acting as agent for the 
Holders of the Notes with full and valid authority so to act or refrain from 
acting, and the Pledgor shall not be obligated or 

                                      -16-
<PAGE>

entitled to make any inquiry respecting such authority.

            Section 17.13  FINAL EXPRESSION.  This Pledge Agreement, together 
with the Indenture and any other agreement executed in connection herewith, 
is intended by the parties as a final expression of this Pledge Agreement and 
is intended as a complete and exclusive statement of the terms and conditions 
thereof.

            Section 17.14.  RIGHTS OF HOLDERS OF THE NOTES.  No Holder of 
Notes shall have any independent rights hereunder other than those rights 
granted to individual Holders of the Notes pursuant to Section 6.07 of the 
Indenture; PROVIDED that nothing in this subsection shall limit any rights 
granted to the Trustee under the Notes or the Indenture.

            Section 17.15.  GOVERNING LAW; SUBMISSION TO JURISDICTION; WAIVER 
OF JURY TRIAL; WAIVER OF DAMAGES.  (a)  THIS PLEDGE AGREEMENT SHALL BE 
GOVERNED BY AND INTERPRETED UNDER THE LAWS OF THE STATE OF NEW YORK, AND ANY 
DISPUTE ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE 
RELATIONSHIP ESTABLISHED BETWEEN THE PLEDGOR, THE TRUSTEE AND THE HOLDERS OF 
THE NOTES IN CONNECTION WITH THIS PLEDGE AGREEMENT, AND WHETHER ARISING IN

                                                                      EXHIBIT A

                       NOTIFICATION AND CONTROL AGREEMENT

            THIS NOTIFICATION AND CONTROL AGREEMENT (the "AGREEMENT") dated 
as of December 23, 1998 by and among Dobson/Sygnet Communications Company 
(the "PLEDGOR") and the United States Trust Company of New York, a bank and 
trust company organized under the new York banking law, in its capacity as 
trustee (the "TRUSTEE") and in its capacity as a bank (the "BANK") at which 
the Pledgor maintains the Collateral Account.

            A.     The Pledgor has granted to the Trustee a security interest 
in the Collateral, pursuant to, and as more particularly described in, a 
Collateral Pledge and Security Agreement dated as of December 23, 1998 
between the Pledgor and the Trustee (as the same may hereafter be amended, 
supplemented or otherwise modified from time to time, the "PLEDGE AGREEMENT"; 
terms defined in the Pledge Agreement and not otherwise defined herein are 
used herein as therein defined).

            B.     Terms defined in Articles 8 or 9 of the Uniform Commercial 
Code as in effect in the State of New York (the "UCC") are used in this 
Agreement (including, without limitation, paragraph A above) as defined in 
Articles 8 or 9, respectively, of the UCC.

            C.     Pursuant to the Pledge Agreement, the Trustee has required 
the execution and delivery of this Agreement.

            NOW, THEREFORE, for valuable consideration and intending to be 
legally bound, the parties hereto agree and acknowledge as follows:

            1.     NOTICE OF SECURITY INTEREST.  The Pledgor and Trustee are 
entering into this Agreement to perfect, and confirm the first priority lien 
of, the Trustee's security interest in the Collateral.  The Bank agrees to 
promptly make all necessary entries or notations in its books and records to 
reflect the Trustee's security interest in the Collateral and to apply any 
value distributed on account of any Collateral as provided in the Pledge 
Agreement without further consent from the Pledgor.  The Bank acknowledges 
that the Trustee has control over the Collateral Account.

            2.     SEPARATE ACCOUNT; TRUSTEE REPRESENTATIONS AND WARRANTIES. 
(a) The Trustee hereby instructs the Bank, and the Bank hereby confirms and 
agrees that, unless the Trustee shall otherwise direct the Bank in writing, 
the Collateral Account is to be maintained separately at all times.

            (b)    The Trustee hereby represents and warrants that it has 
acquired its security interest in, and security entitlement to, the 
Collateral for value and without notice of any adverse claim thereto.  
Without limiting the generality of the foregoing, the Collateral is not, to 
the Trustee's knowledge, subject to any Lien granted by the Trustee in favor 
of any securities intermediary 

<PAGE>

(including, without limitation, the Bank or the Federal Reserve Bank of New 
York) and the Trustee has not knowingly or purposefully caused or permitted 
the Collateral to become subject to any Lien created by or arising through 
the Bank.

            3.     CONTROL.  The Bank hereby agrees, upon written direction 
from the Trustee and in accordance with the terms of the Pledge Agreement, 
and without further consent from the Pledgor, (a) to comply with all 
instructions, entitlement orders and directions of any kind originated by the 
Trustee concerning the Collateral, to liquidate or otherwise dispose of the 
Collateral as and to the extent directed by the Trustee and pay over to the 
Trustee all proceeds and other value therefrom or otherwise distributed with 
respect thereto without any set off or deduction, and (b) except as otherwise 
directed by the Trustee, not to comply with the instructions or directions of 
the Pledgor or any other person.

            4.     OTHER AGREEMENTS; TERMINATION; SUCCESSOR TRUSTEES.  The 
Bank shall simultaneously send to the Trustee and the Pledgor copies of all 
notices given and statements rendered pursuant to the Collateral Account.  So 
long as the Pledge Agreement remains in effect, neither the Pledgor nor the 
Bank shall terminate the Collateral Account without thirty (30) days' prior 
written notice to the other party and the Trustee.  In the event of any 
conflict between the provisions of this Agreement and any other agreement 
governing the Collateral Account, the provisions hereof shall control.  In 
the event the Trustee no longer serves as Trustee for the Collateral, the 
Collateral Account shall be transferred to a successor trustee satisfactory 
to the Trustee, provided that prior to such transfer, such successor trustee 
executes an agreement that is in all material respects the same as this 
Agreement or is otherwise in form and substance satisfactory to the Trustee.

            5.     INDEMNITY.  The Pledgor shall indemnify and hold the 
Trustee and the Bank harmless from any and all losses, claims, damages, 
liabilities, expenses and fees, including reasonable counsel fees, resulting 
from the execution of or performance under this Agreement and delivery by the 
Trustee of all or any part of the Collateral to the Bank pursuant to this 
Agreement, except claims, losses or liabilities resulting from the Trustee's 
or the Bank's gross negligence, bad faith or willful misconduct as determined 
by a final judgment of a court of competent jurisdiction.  This 
indemnification shall survive the termination of this Agreement.

            6.     PROTECTION OF BANK.   Except as required by Paragraph 3 
hereof, the Bank shall have no duty to determine that the amount and form of 
assets constituting Collateral comply with any applicable requirements.  The 
Bank may rely and shall be protected in acting upon any notice, instruction, 
or other communication which it reasonably believes to be genuine and 
authorized.

            7.     TERMINATION/RELEASE OF COLLATERAL.  This Agreement shall 
terminate 

                                      -2-
<PAGE>

automatically upon receipt by the Bank of written notice executed by two 
officers of the Trustee holding titles of Vice President or higher that (a) 
all of the obligations secured by the Collateral have been satisfied, or (b) 
all of the Collateral has been released, whichever is sooner, and the Bank 
shall thereafter be relieved of all duties and obligations hereunder.

            8.     WAIVER AND SUBORDINATION OF RIGHTS.  The Bank hereby 
waives its right to set off any obligations of the Pledgor to the Bank 
against any or all assets held by the Trustee as Collateral, and hereby 
agrees that any and all liens, encumbrances, claims or security interests 
which the Bank may have against the Collateral, either now or in the future 
are and shall be subordinate and junior to the prior payment in full of all 
obligations of the Pledgor now or hereafter existing under the Indenture, 
Notes and all other documents related thereto whether for principal, interest 
(including, without limitation, interest, as provided in the Notes, whether 
or not such interest accrues after the filing of such petition for purposes 
of the Bankruptcy Code or is an allowed claim in such proceeding), 
indemnities, fees, premiums, expenses or otherwise. The Bank will not agree 
with any third party that the Bank will comply with any instructions or 
directions of any kind concerning the Collateral originated by such third 
party without the prior written consent of the Trustee.  Except for the 
claims and interests of the Trustee and the Pledgor in the Collateral, the 
Bank does not know of any claim to or security interest or other interest in 
the Collateral.

            9.     EXPENSES.  The Pledgor shall pay upon demand all fees, 
costs and expenses (including reasonable fees and expenses of counsel) of 
enforcing the Bank's rights and remedies upon any breach (by the Trustee or 
the Pledgor) of any of the provisions of this Agreement.

            10.    NOTICES.  All notices, demands, requests, consents, 
approvals and other communications required or permitted hereunder must be in 
writing and will be effective upon receipt if delivered personally, or if 
sent by facsimile transmission with confirmation of delivery, or by 
nationally recognized overnight courier service with confirmation of 
delivery, to the Pledgor's and the Trustee's addresses as set forth in the 
Pledge Agreement, and to the Bank's address as set forth below, or to such 
other address as any party may give to the others in writing for such purpose.

            11.    CHANGES IN WRITING.  No modification, amendment or waiver 
of any provision of this Agreement nor consent to any departure by any party 
therefrom will be effective unless made in writing signed by the parties 
hereto, and then such waiver or consent shall be effective only in the 
specific instance and for the purpose for which given.

            12.    ENTIRE AGREEMENT.  This Agreement (including the documents 
and instruments referred to herein) constitutes the entire agreement and 
supersedes all other prior agreements and understandings, both written and 
oral, among the parties with respect to the subject matter hereof.

                                      -3-

            13.    COUNTERPARTS.  This Agreement may be signed in any number 
of counterpart copies and by the parties hereto on separate counterparts 
(including by facsimile transmission), but all such copies shall constitute 
one and the same instrument.

            14.    SUCCESSORS AND ASSIGNS.  This Agreement will be binding 
upon and inure to the benefit of the parties hereto and their respective 
heirs, executors, administrators, successors and assigns.

            15.    GOVERNING LAW AND JURISDICTION.  This Agreement has been

State of New York.  THIS AGREEMENT WILL BE INTERPRETED AND THE RIGHTS AND 
LIABILITIES OF THE PARTIES HERETO DETERMINED IN ACCORDANCE WITH THE LAWS OF 
THE STATE OF NEW YORK.  Each of the parties hereby irrevocably submits for 
itself and its property in any legal action or proceeding relating to this 
Agreement, or for recognition and enforcement of any judgment in respect 
thereof, to the non-exclusive general jurisdiction and venue of the courts of 
the State of New York, the courts of the United States of America in New 
York, and appellate courts from any thereof.

            16.    WAIVER OF JURY TRIAL.  EACH OF THE PARTIES HERETO 
IRREVOCABLY WAIVES ANY AND ALL RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY 
ACTION, PROCEEDING OR CLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) OF 
ANY NATURE RELATING TO THIS AGREEMENT, ANY DOCUMENTS EXECUTED IN CONNECTION 
WITH THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED IN ANY OF SUCH DOCUMENTS. 
EACH PARTY HERETO ACKNOWLEDGES THAT THE FOREGOING WAIVER IS KNOWING AND 
VOLUNTARY.

Statement to be declared effective under the Securities Act and remain effective
until the closing of the Exchange Offer and (ii) to consummate the Exchange
Offer on or prior to the 180th calendar day following the Closing Date.

            (b)    Upon the effectiveness of the Exchange Offer Registration
Statement, the Company shall promptly commence the Exchange Offer, it being the
objective of such Exchange Offer to enable each Holder electing to exchange
Notes for Exchange Notes (assuming that such Holder (x) is not an "affiliate" of
the Company within the meaning of the Securities Act, (y) is not a broker-dealer
that acquired the Notes in a transaction other than as a part of its
market-making or other trading activities and (z) if such Holder is not a
broker-dealer, acquires the Exchange Notes in the ordinary course of such
Holder's business, is not participating in the distribution of the Exchange
Notes and has no arrangements or understandings with any person to participate
in the distribution of the Exchange Notes) to resell such Exchange Notes from
and after their receipt without any limitations or restrictions under the
Securities Act and without material restrictions under the securities laws of a
substantial proportion of the several states of the United States.

<PAGE>

            (c)    In connection with the Exchange Offer, the Company shall mail
to each Holder a copy of the Prospectus forming part of the Exchange Offer
Registration Statement, together with an appropriate letter of transmittal and
related documents, stating, in addition to such other disclosures as are
required by applicable law:

            (i)    that the Exchange Offer is being made pursuant to this
     Agreement and that all Notes validly tendered will be accepted for
     exchange;

            (ii)   the dates of acceptance for exchange;

            (iii)  that any Note not tendered will remain outstanding and
     continue to accrue interest, but will not retain any rights under this
     Agreement;

            (iv)   that Holders electing to have a Note exchanged pursuant to
     the Exchange Offer will be required to surrender such Note, together with
     the enclosed letters of transmittal, to the institution and at the address
     (located in the Borough of Manhattan, The City of New York) specified in
     the notice prior to the close of business on the last day of acceptance for
     exchange; and

            (v)    that Holders will be entitled to withdraw their election, not
     later than the close of business on the last day of acceptance for
     exchange, by sending to the institution and at the address (located in the
     Borough of Manhattan, The City of New York) specified in the notice a
     telegram, telex, facsimile transmission or letter setting forth the name of
     such Holder, the principal amount of Notes delivered for exchange and a
     statement that such Holder is withdrawing his election to have such Notes
     exchanged; and shall keep the Exchange Offer open for acceptance for not
     less than 30 days and not more than 45 days (or longer if required by
     applicable law) after the date notice thereof is mailed to the Holders;
     utilize the services of a depositary for the Exchange Offer with an address
     in the Borough of Manhattan, The City of New York; and comply in all
     respects with all applicable laws relating to the Exchange Offer.

            (d)    As soon as practicable after the close of the Exchange Offer,
the Company shall:

            (i)    accept for exchange all Notes duly tendered and not validly
     withdrawn pursuant to the Exchange Offer;

            (ii)   deliver to the Trustee for cancellation all Notes so accepted
     for exchange; and

            (iii)  cause the Trustee promptly to authenticate and deliver to
     each Holder Exchange Notes equal in principal amount to the Notes of such
     Holder so accepted for exchange.

<PAGE>

            (e)    The Initial Purchasers and the Company acknowledge that,
pursuant to interpretations by the staff of the Commission of Section 5 of the
Securities Act, and in the absence of an applicable exemption therefrom, each
Exchanging Dealer is required to deliver a Prospectus in connection with a sale
of any Exchange Notes received by such Exchanging Dealer pursuant to the
Exchange Offer in exchange for Notes acquired for its own account as a result of
market-making activities or other trading activities.  Accordingly, the Company
shall:

            (i)    include the information set forth in Annex A hereto on the
     cover of the Exchange Offer Registration Statement, in Annex B hereto in
     the forepart of the Exchange Offer Registration Statement in a section
     setting forth details of the Exchange Offer, in Annex C hereto in the
     underwriting or plan of distribution section of the Prospectus forming a
     part of the Exchange Offer Registration Statement, and in Annex D hereto in
     the letter of transmittal delivered pursuant to the Exchange Offer; and

            (ii)   use its best efforts to keep the Exchange Offer Registration
     Statement continuously effective under the Securities Act during the
     Exchange Offer Registration Period for delivery of the prospectus included
     therein by Exchanging Dealers in connection with sales of Exchange Notes
     received pursuant to the Exchange Offer, as contemplated by Section 4(h)
     below; PROVIDED, HOWEVER, that the Company shall not be required to
     maintain the effectiveness of the Exchange Offer Registration Statement for
     more than 30 days following the consummation of the Exchange Offer unless
     the Company has been notified in writing on or prior to the 30th day
     following the consummation of the Exchange Offer by one or more Exchanging
     Dealers that such Holder has received Exchange Notes as to which it will be
     required to deliver a prospectus upon resale.

            (f)    In the event that the Initial Purchasers determine that they
are not eligible to participate in the Exchange Offer with respect to the
exchange of Notes constituting any portion of an unsold allotment, upon the
effectiveness of the Shelf Registration Statement as contemplated by Section 3
hereof and at the request of the Initial Purchasers, the Company shall issue and
deliver to the Initial Purchasers, or to the party purchasing Notes registered
under the Shelf Registration Statement from the Initial Purchasers, in exchange
for such Notes, a like principal amount of Exchange Notes.  The Company shall
use its best efforts to cause the CUSIP Service Bureau to issue the same CUSIP
number for such Exchange Notes as for Exchange Notes issued pursuant to the
Exchange Offer.

            (g)    The Company shall use its best efforts to complete the
Exchange Offer as provided above and shall comply with the applicable
requirements of the Securities Act, the Exchange Act and other applicable laws
and regulations in connection with the Exchange Offer.  The Exchange Offer shall
not be subject to any conditions, other than that (i) the Exchange Offer does
not violate applicable law or any applicable interpretation of the staff of the
Commission, (ii) no action or proceeding shall have been instituted or
threatened in any court or by any governmental agency which might materially
impair the ability of the Company to

<PAGE>

proceed with the Exchange Offer, and no material adverse development shall have
occurred in any existing action or proceeding with respect to the Company and
(iii) all governmental approvals shall have been obtained, which approvals the
Company deems necessary for the consummation of the Exchange Offer.  The Company
shall inform the Initial Purchasers, upon their request, of the names and
addresses of the Holders to whom the Exchange Offer is made, and the Initial
Purchasers shall have the right, subject to applicable law, to contact such
Holders and otherwise facilitate the tender of Notes in the Exchange Offer.

            3.     SHELF REGISTRATION.  If (i) because of any change in law or
applicable interpretations thereof by the Commission's staff, the Company
determines upon advice of its outside counsel that it is not permitted to effect
the Exchange Offer as contemplated by Section 2 hereof, or (ii) for any reason
other than those specified in clause (i) above, the Exchange Offer is not
consummated within 180 days of the Closing Date, or (iii) the Initial Purchasers
so request with respect to Notes held by them within 90 days following
consummation of the Exchange Offer, or (iv) any Holder (other than an Initial
Purchaser) is not eligible to participate in the Exchange Offer or has
participated in the Exchange Offer and has received Exchange Notes that are not
freely tradeable or (v) in the case where the Initial Purchasers participate in
the Exchange Offer or acquire Exchange Notes pursuant to Section 2(f) hereof,
the Initial Purchasers do not receive freely tradeable Exchange Notes in
exchange for Notes constituting any portion of an unsold allotment (it being
understood that, for purposes of this Section 3, (x) the requirement that the
Initial Purchasers deliver a Prospectus containing the information required by
Items 507 and/or 508 of Regulation S-K under the Securities Act in connection
with sales of Exchange Notes acquired in exchange for such Notes shall result in
such Exchange Notes being not "freely tradeable" and (y) the requirement that an
Exchanging Dealer deliver a Prospectus in connection with sales of Exchange
Notes acquired in the Exchange Offer in exchange for Notes acquired as a result
of market-making activities or other trading activities shall not result in such
Exchange Notes being not "freely tradeable"), the following provisions shall
apply:

            (a)    The Company shall, as promptly as practicable, file with the
     Commission a Shelf Registration Statement relating to the offer and sale of
     the Notes or the Exchange Notes, as applicable, by the Holders from time to
     time in accordance with the methods of distribution elected by such Holders
     and set forth in such Shelf Registration Statement and Rule 415 under the
     Securities Act, PROVIDED that, with respect to Exchange Notes received by
     the Initial Purchasers in exchange for Notes constituting any portion of an
     unsold allotment, the Company may, if permitted by current interpretations
     by the Commission's staff, file a post-effective amendment to the Exchange
     Offer Registration Statement containing the information required by
     Regulation S-K Items 507 and/or 508, as applicable, in satisfaction of its
     obligations under this paragraph (a) with respect thereto, and any such
     Exchange Offer Registration Statement, as so amended, shall be referred to
     herein as, and governed by the provisions herein applicable to, a Shelf
     Registration Statement.

            (b)    The Company shall use its best efforts to cause the Shelf
     Registration

<PAGE>

     Statement to be declared effective under the Securities Act as promptly as
     possible after filing such Shelf Registration Statement pursuant to this
     Section 3 and to keep such Shelf Registration Statement continuously
     effective in order to permit the Prospectus contained therein to be usable
     by Holders for a period of two years from the date the Shelf Registration
     Statement is declared effective by the Commission or such shorter period
     that will terminate when all the Notes or Exchange Notes, as applicable,
     covered by the Shelf Registration Statement have been sold pursuant to the
     Shelf Registration Statement (in any such case, such period being called
     the "Shelf Registration Period"). The Company shall be deemed not to have
     used its best efforts to keep the Shelf Registration Statement effective
     during the requisite period if it voluntarily takes any action that would
     result in Holders of Notes covered thereby not being able to offer and sell
     such Notes during that period, unless (i) such action is required by
     applicable law, (ii) the Company complies with this Agreement or (iii) such
     action is taken by the Company in good faith and for valid business reasons
     (not including avoidance of the Company's obligations hereunder), including
     the acquisition or divestiture of assets, so long as the Company promptly
     thereafter complies with the requirements of Section 4(l) hereof, if
     applicable.

            4.     REGISTRATION PROCEDURES.  In connection with any Shelf
Registration Statement and, to the extent applicable, any Exchange Offer
Registration Statement, the following provisions shall apply:

            (a)    The Company shall, within a reasonable time prior to the
     filing of any Registration Statement, any Prospectus, any amendment to a
     Registration Statement or amendment or supplement to a Prospectus or any
     document which is to be incorporated by reference into a Registration
     Statement or a Prospectus after initial filing of a Registration Statement,
     provide copies of such document to the Initial Purchasers and their counsel
     (and, in the case of a Shelf Registration Statement, the Holders and their
     counsel, upon their request) and make such representatives of the Company
     as shall be reasonably requested by the Initial Purchasers or their counsel
     (and, in the case of a Shelf Registration Statement, the Majority Holders
     or their counsel) available for discussion of such document, and shall not
     at any time file or make any amendment to the Registration Statement, any
     Prospectus or any amendment of or supplement to a Registration Statement or
     a Prospectus or any document which is to be incorporated by reference into
     a Registration Statement or a Prospectus, of which the Initial Purchasers
     and their counsel (and, in the case of a Shelf Registration Statement, the
     Holders and their counsel) shall not have previously been advised and
     furnished a copy or to which the Initial Purchasers or their counsel (and,
     in the case of a Shelf Registration Statement, the Holders or their
     counsel) shall object, except for any amendment or supplement or document
     (a copy of which has been previously furnished to the Initial Purchasers
     and their counsel (and, in the case of a Shelf Registration Statement, the
     Majority Holders and their counsel, upon their request)) which counsel to
     the Company shall advise the Company, in the form of a written opinion, is
     required in order to comply with

<PAGE>

     applicable law; each of the Initial Purchasers agrees that, if it receives
     timely notice and drafts under this clause (a), it will not take actions or
     make objections pursuant to this clause (a) such that the Company is unable
     to comply with its obligations under Section 2.

            (b)    The Company shall ensure that:

                   (i)    any Registration Statement and any amendment thereto
            and any Prospectus contained therein and any amendment or supplement
            thereto complies in all material respects with the Securities Act
            and the rules and regulations thereunder;

                   (ii)   any Registration Statement and any amendment thereto
            does not, when it becomes effective, contain an untrue statement of
            a material fact or omit to state a material fact required to be
            stated therein or necessary to make the statements therein not
            misleading; and

                   (iii)  any Prospectus forming part of any Registration
            Statement, including any amendment or supplement to such Prospectus,
            does not include an untrue statement of a material fact or omit to
            state a material fact necessary in order to make the statements
            therein, in light of the circumstances under which they were made,
            not misleading.

            (c)    (1)  The Company shall advise the Initial Purchasers and, in
     the case of a Shelf Registration Statement, the Holders of Notes covered
     thereby, and, if requested by the Initial Purchasers or any such Holder,
     confirm such advice in writing:

                   (i)    when a Registration Statement and any amendment
            thereto has been filed with the Commission and when the Registration
            Statement or any post-effective amendment thereto has become
            effective; and

                   (ii)   of any request by the Commission for amendments or
            supplements to the Registration Statement or the Prospectus included
            therein or for additional information.

            (2)    During the Shelf Registration Period or the Exchange Offer
     Registration Period, as applicable, the Company shall advise the Initial
     Purchasers and, in the case of a Shelf Registration Statement, the Holders
     of Notes covered thereby, and, in the case of an Exchange Offer
     Registration Statement, any Exchanging Dealer that has provided in writing
     to the Company a telephone or facsimile number and address for notices,
     and, if requested by the Initial Purchasers or any such Holder or
     Exchanging Dealer, confirm such advice in writing:

                   (i)    of the issuance by the Commission of any stop order
            suspending

<PAGE>

     the effectiveness of the Registration Statement or the initiation of any
     proceedings for that purpose;

                   (ii)   of the receipt by the Company of any notification with
            respect to the suspension of the qualification of the Notes included
            therein for sale in any jurisdiction or the initiation or
            threatening of any proceeding for such purpose; and

                   (iii)  of the happening of any event that requires the making
            of any changes in the Registration Statement or the Prospectus so
            that, as of such date, the Registration Statement or the Prospectus
            does not include an untrue statement of a material fact or omit to
            state a material fact necessary to make the statements therein (in
            the case of the Prospectus, in light of the circumstances under
            which they were made) not misleading (which advice shall be
            accompanied by an instruction to suspend the use of the Prospectus
            until the requisite changes have been made).

            (d)    The Company shall use its best efforts to obtain the
     withdrawal of any order suspending the effectiveness of any Registration
     Statement at the earliest possible time.

            (e)    The Company shall furnish to each Holder of Notes covered by
     any Shelf Registration Statement that so requests, without charge, at least
     one copy of such Shelf Registration Statement and any post-effective
     amendment thereto, including financial statements and schedules, and, if
     the Holder so requests in writing, all exhibits thereto.

            (f)    The Company shall, during the Shelf Registration Period,
     deliver to each Holder of Notes covered by any Shelf Registration
     Statement, without charge, as many copies of the Prospectus (including each
     preliminary Prospectus) included in such Shelf Registration Statement and
     any amendment or supplement thereto as such Holder may reasonably request;
     and the Company consents to the use of the Prospectus or any amendment or
     supplement thereto by each of the selling Holders of Notes in connection
     with the offering and sale of the Notes covered by the Prospectus or any
     amendment or supplement thereto.

            (g)    The Company shall furnish to each Exchanging Dealer that so
     requests, without charge, at least one copy of the Exchange Offer
     Registration Statement and any post-effective amendment thereto, including
     financial statements and schedules, any documents incorporated by reference
     therein and, if the Exchanging Dealer so requests in writing, all exhibits
     thereto.

            (h)    The Company shall, during the Exchange Offer Registration
     Period, promptly deliver to each Exchanging Dealer, without charge, as many
     copies of the

<PAGE>

     Prospectus included in such Exchange Offer Registration Statement and any
     amendment or supplement thereto as such Exchanging Dealer may reasonably
     request for delivery by such Exchanging Dealer in connection with a sale of
     Exchange Notes received by it pursuant to the Exchange Offer; and the
     Company consents to the use of the Prospectus or any amendment or
     supplement thereto by any such Exchanging Dealer, as provided in Section
     2(e) above.

            (i)    Each Holder of Notes and each Exchange Dealer agrees by its
     acquisition of such Notes or Exchange Notes to be sold by such Exchange
     Dealer, as the case may be, that, upon actual receipt of any notice from
     the Company of the happening of any event of the kind described in
     paragraph (c)(2)(i), (c)(2)(ii), or (c)(2)(iii) of this Section 4, such
     Holder will forthwith discontinue disposition of such Notes covered by such
     Registration Statement or Prospectus or Exchange Notes to be sold by such
     Holder or Exchange Dealer, as the case may be, until such Holder's or
     Exchange Dealer's receipt of the copies of the supplemented or amended
     Prospectus contemplated by Section 4(l) hereof, or until it is advised in
     writing by the Company that the use of the applicable Prospectus may be
     resumed, and has received copies of any amendments or supplements thereto.
     In the event that the Company shall give any such notice, the Exchange
     Offer Registration Period shall be extended by the number of days during
     such periods from and including the date of the giving of such notice to
     and including the date when each seller of the Exchange Notes covered by
     such Registration Statement or Exchange Notes to be sold by such Exchange
     Dealer, as the case may be, shall have received (x) the copies of the
     supplemented or amended Prospectus contemplated by Section 4(l) hereof or
     (y) the advice in writing.

            (j)    Prior to the Exchange Offer or any other offering of Notes
     pursuant to any Registration Statement, the Company shall register or
     qualify or cooperate with the Holders of Notes included therein and their
     respective counsel in connection with the registration or qualification of
     such Notes for offer and sale under the securities or blue sky laws of such
     states as any such Holders reasonably request in writing and do any and all
     other acts or things necessary or advisable to enable the offer and sale in
     such states of the Notes covered by such Registration Statement; PROVIDED,
     HOWEVER, that the Company will not be required to qualify as a foreign
     corporation or as a dealer in securities in any jurisdiction in which it is
     not then so qualified, to file any general consent to service of process or
     to take any action that would subject it to general service of process in
     any such jurisdiction where it is not then so subject or to subject itself
     to taxation in respect of doing business in any jurisdiction in which it is
     not otherwise so subject.

            (k)    The Company shall cooperate with the Holders to facilitate
     the timely preparation and delivery of certificates representing Notes to
     be sold pursuant to any Registration Statement free of any restrictive
     legends and in denominations of $1,000 or an integral multiple thereof and
     registered in such names as Holders may request prior to

<PAGE>

     sales of Notes pursuant to such Registration Statement.

            (l)    Upon the occurrence of any event contemplated by paragraph
     (c)(2)(iii) of this Section 4, the Company shall promptly prepare and file
     a post-effective amendment to any Registration Statement or an amendment or
     supplement to the related Prospectus or any other required document so
     that, as thereafter delivered to purchasers of the Notes included therein,
     the Prospectus will not include an untrue statement of a material fact or
     omit to state any material fact necessary to make the statements therein,
     in light of the circumstances under which they were made, not misleading
     and, in the case of a Shelf Registration Statement, notify the Holders to
     suspend use of the Prospectus as promptly as practicable after the
     occurrence of such an event.  Notwithstanding the foregoing, the Company
     shall not be required to amend or supplement a Shelf Registration
     Statement, any related Prospectus or any document incorporated therein by
     reference, for a period not to exceed an aggregate of 30 days in any
     calendar year, if the Company determines in its good faith judgment that
     the disclosure of such event at such time would have a material adverse
     effect on the business, operations, or prospects of the Company or the
     disclosure otherwise related to a pending material business transaction
     that has not yet been publicly disclosed.

            (m)    Not later than the effective date of any such Registration
     Statement hereunder, the Company shall provide a CUSIP number for the Notes
     or Exchange Notes, as the case may be, registered under such Registration
     Statement, and provide the Trustee with certificates for such Notes or
     Exchange Notes, in a form eligible for deposit with The Depository Trust
     Company.

            (n)    The Company shall use its best efforts to comply with all
     applicable rules and regulations of the Commission and shall make generally
     available to its security holders as soon as practicable after the
     effective date of the applicable Registration Statement an earnings
     statement meeting the requirements of Rule 158 under the Securities Act.

            (o)    The Company shall cause the Indenture to be qualified under
     the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), in
     a timely manner.

            (p)    The Company may require each Holder of Notes to be sold
     pursuant to any Shelf Registration Statement to furnish to the Company such
     information regarding the Holder and the distribution of such Notes as the
     Company may from time to time reasonably require for inclusion in such
     Registration Statement.

            (q)    The Company shall, if requested, promptly incorporate in a
     Prospectus supplement or post-effective amendment to a Shelf Registration
     Statement, such information as the Managing Underwriters, if any, and
     Majority Holders reasonably agree should be included therein, and shall
     make all required filings of such Prospectus

<PAGE>

     supplement or post-effective amendment promptly upon notification of the
     matters to be incorporated in such Prospectus supplement or post-effective
     amendment.

            (r)    In the case of any Shelf Registration Statement, the Company
     shall enter into such agreements (including underwriting agreements) and
     take all other appropriate actions in order to expedite or to facilitate
     the registration or the disposition of any Notes included therein, and in
     connection therewith, if an underwriting agreement is entered into, cause
     the same to contain indemnification provisions and procedures no less
     favorable than those set forth in Section 6 (or such other provisions and
     procedures acceptable to the Majority Holders and the Managing
     Underwriters, if any) with respect to all parties to be indemnified
     pursuant to Section 6.

            (s)    In the case of any Shelf Registration Statement, the Company
     shall:

                   (i)     make reasonably available for inspection by the
            Holders of Notes to be registered thereunder, any underwriter
            participating in any disposition pursuant to such Shelf Registration
            Statement, and any attorney, accountant or other agent retained by
            the Holders or any such underwriter all relevant financial and other
            records, pertinent corporate documents and properties of the Company
            and any of its subsidiaries;

                   (ii)   cause the Company's officers, directors and employees
            to supply all relevant information reasonably requested by the
            Holders or any such underwriter, attorney, accountant or agent in
            connection with any such Registration Statement as is customary for
            similar due diligence examinations and make such representatives of
            the Company as shall be reasonably requested by the Initial
            Purchasers or Managing Underwriters, if any, available for
            discussion of any such Registration Statement; PROVIDED, HOWEVER,
            that any non-public information that is designated in writing by the
            Company, in good faith, as confidential at the time of delivery of
            such information shall be kept confidential by the Holders or any
            such underwriter, attorney, accountant or agent, unless such
            disclosure is made in connection with a court proceeding or required
            by law, or such information becomes available to the public
            generally or through a third party without an accompanying
            obligation of confidentiality other than as a result of a disclosure
            of such information by any such Holder, underwriter, attorney,
            accountant or agent;

                   (iii)  make such representations and warranties to the
            Holders of Notes registered thereunder and the underwriters, if any,
            in form, substance and scope as are customarily made by issuers to
            underwriters in similar underwritten offerings as may be reasonably
            requested by them;
                   (iv)   obtain opinions of counsel to the Company and updates
            thereof (which counsel and opinions (in form, scope and substance)
            shall be reasonably

<PAGE>

            satisfactory to the Managing Underwriters, if any) addressed to each
            selling Holder and the underwriters, if any, covering such matters
            as are customarily covered in opinions requested in similar
            underwritten offerings and such other matters as may be reasonably
            requested by such Holders and underwriters;

                   (v)    obtain "cold comfort" letters and updates thereof from
            the independent certified public accountants of the Company (and, if
            necessary, any other independent certified public accountants of any
            subsidiary of the Company or of any business acquired by the Company
            for which financial statements and financial data are, or are
            required to be, included in the Registration Statement), addressed
            to the underwriters, if any, and use reasonable efforts to have such
            letter addressed to the selling Holders of Notes registered
            thereunder (to the extent consistent with Statement on Auditing
            Standards No. 72 of the American Institute of Certified Public
            Accountants (AICPA) ("SAS 72")), in customary form and covering
            matters of the type customarily covered in "cold comfort" letters in
            connection with similar underwritten offerings, or if the provision
            of such "cold comfort" letters is not permitted by SAS 72 or if
            requested by the Initial Purchasers or their counsel in lieu of a
            "cold comfort" letter, an agreed-upon procedures letter under
            Statement on Auditing Standards No. 75 of the AICPA, covering
            matters requested by the Initial Purchasers or their counsel; and

                   (vi)   deliver such documents and certificates as may be
            reasonably requested by the Majority Holders and the Managing
            Underwriters, if any, and customarily delivered in similar
            offerings, including those to evidence compliance with Section 4(l)
            and with any conditions contained in the underwriting agreement or
            other agreement entered into by the Company.

            The foregoing actions set forth in clauses (iii), (iv), (v) and (vi)
     of this Section 4(s) shall be performed at (A) the effectiveness of such
     Shelf Registration Statement and each post-effective amendment thereto and
     (B) each closing under any underwriting or similar agreement as and to the
     extent required thereunder.

            (t)    The Company shall, in the case of a Shelf Registration, use
     their best efforts to cause all Notes to be listed on any securities
     exchange or any automated quotation system on which similar securities
     issued by the Company are then listed if requested by the Majority Holders,
     to the extent such Notes satisfy applicable listing requirements.

            (u)    The Company shall use its best efforts to cause the Exchange
     Notes or Notes, as the case may be, to be rated by two nationally
     recognized statistical rating organizations (as such term is defined in
     Rule 436(g)(2) under the 1933 Act).

<PAGE>

            5.     REGISTRATION EXPENSES; REMEDIES.  (a)  The Company shall bear
all expenses incurred in connection with the performance of its obligations
under Sections 2, 3 and 4 hereof, including without limitation:  (i) all
Commission, stock exchange or National Association of Securities Dealers, Inc.
registration and filing fees, (ii) all fees and expenses incurred in connection
with compliance with state securities or blue sky laws (including reasonable
fees and disbursements of counsel for any underwriters or Holders in connection
with blue sky qualification of any of the Exchange Notes or Notes), (iii) all
expenses of any persons in preparing or assisting in preparing, word processing,
printing and distributing any Registration Statement, any Prospectus, any
amendments or supplements thereto, any underwriting agreements, securities sales
agreements and other documents relating to the performance of and compliance
with this Agreement, (iv) all rating agency fees, if any, (v) all fees and
disbursements relating to the qualification of the Indenture under applicable
securities laws, (vi) the fees and disbursements of the Trustee and its counsel,
(vii) the fees and disbursements of counsel for the Company and, in the case of
a Shelf Registration Statement, the fees and disbursements of one counsel for
the Holders (which counsel shall be selected by the Majority Holders and which
counsel may also be counsel for the Initial Purchasers) and in the case of any
Exchange Offer Registration Statement, the fees and expenses of counsel to the
Initial Purchasers acting in connection therewith and (viii) the fees and
disbursements of the independent public accountants of the Company and Sygnet
Wireless, Inc., including the expenses of any special audits or "cold comfort"
letters required by or incident to such performance and compliance, but
excluding fees and expenses of counsel to the underwriters (other than fees and
expenses set forth in clause (ii) above) or the Holders and underwriting
discounts and commissions and transfer taxes, if any, relating to the sale or
disposition of Notes by a Holder.

            (b)    The Notes provide that if the Exchange Offer is not
consummated on or prior to the 180th calendar day following the Closing Date or
a Shelf Registration Statement is not declared effective when required, the
annual interest rate on the Notes will increase by 0.5% per annum until the
consummation of the Exchange Offer or the effectiveness of a Shelf Registration
Statement, as the case may be.

            (c)    Without limiting the remedies available to the Initial
Purchasers and the Holders, the Company acknowledges that any failure by the
Company to comply with its obligations under Sections 2 and 3 hereof may result
in material irreparable injury to the Initial Purchasers or the Holders for
which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, the Initial Purchasers or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Sections 2 and
3 hereof.

            6.     INDEMNIFICATION AND CONTRIBUTION.  (a)  In connection with
any Registration Statement, the Company agrees to indemnify and hold harmless
each Holder of Notes covered thereby (including the Initial Purchasers and, with
respect to any Prospectus delivery as contemplated by Sections 2(e) and 4(h)
hereof, each Exchanging Dealer) the

<PAGE>

directors, officers, employees and agents of such Holder and each person who
controls such Holder within the meaning of either the Securities Act or the
Exchange Act, against any and all losses, claims, damages or liabilities, joint
or several, to which they or any of them may become subject under the Securities
Act, the Exchange Act or other federal or state statutory law or regulation, at
common law or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in such
Registration Statement as originally filed or in any amendment thereof, or in
any preliminary Prospectus or Prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein (in the case of the Prospectus, in
light of the circumstances under which they were made) not misleading, and
agrees to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage or liability (or action in respect
thereof); PROVIDED, HOWEVER, that the Company will not be liable in any case to
the extent that any such loss, claim, damage or liability arises out of or is
based upon any such untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of any such indemnified
party specifically for inclusion therein; PROVIDED FURTHER, HOWEVER, that the
Company will not be liable in any case with respect to any untrue statement or
omission or alleged untrue statement or omission made in any preliminary
Prospectus or Prospectus, or in any amendment thereof or supplement thereto to
the extent that any such loss, claim, damage or liability (or action in respect
thereof) resulted from the fact that any indemnified party sold Notes or
Exchange Notes to a person to whom there was not sent or given, at or prior to
the written confirmation of such sale, a copy of the Prospectus as then amended
or supplemented, if the Company had previously complied with the provisions of
Section 4(c)(2) and 4(f) or 4(h) hereof and if the untrue statement contained in
or omission from such preliminary Prospectus or Prospectus was corrected in the
Prospectus as then amended or supplemented.  This indemnity agreement will be in
addition to any liability that the Company may otherwise have.

            The Company also agrees to indemnify or contribute to Losses of, as
provided in Section 6(d) hereof, any underwriters of Notes registered under a
Shelf Registration Statement, their employees, officers, directors and agents
and each person who controls such underwriters on the same basis as that of the
indemnification of the Initial Purchasers and the selling Holders provided in
this Section 6(a) and shall, if requested by any Holder, enter into an
underwriting agreement reflecting such agreement, as provided in Section 4(r)
hereof.

            (b)    Each Holder of Notes covered by a Registration Statement
(including the Initial Purchasers and, with respect to any Prospectus delivery
as contemplated by Sections 2(e) and 4(h) hereof, each Exchanging Dealer)
severally agrees to indemnify and hold harmless (i) the Company, (ii) each of
the directors of the Company, (iii) each of the officers of the Company who
signs such Registration Statement and (iv) each Person who controls the Company
within the meaning of either the Securities Act or the Exchange Act to the same

<PAGE>

extent as the foregoing indemnity from the Company to each such Holder, but only
with respect to written information furnished to the Company by or on behalf of
such Holder specifically for inclusion in the documents referred to in the
foregoing indemnity.  This indemnity agreement will be in addition to any
liability that any such Holder may otherwise have.

            (c)    Promptly after receipt by an indemnified party under this
Section 6 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 6, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve the indemnifying party from liability under paragraph (a) or
(b) above unless and to the extent it did not otherwise learn of such action and
such failure results in the forfeiture by the indemnifying party of substantial
rights and defenses, and (ii) will not, in any event, relieve the indemnifying
party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraph (a) or (b) above.  The
indemnifying party shall be entitled to appoint counsel (including local
counsel) of the indemnifying party's choice at the indemnifying party's expense
to represent the indemnified party in any action for which indemnification is
sought (in which case the indemnifying party shall not thereafter be responsible
for the fees and expenses of any separate counsel retained by the indemnified
party or parties except as set forth below); PROVIDED, HOWEVER, that such
counsel shall be reasonably satisfactory to the indemnified party.
Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel (and local counsel) if (i) the use of counsel chosen by the
indemnifying party to represent the indemnified party would present such counsel
with a conflict of interest, (ii) the actual or potential defendants in, or
targets of, any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties that are different from or additional to those available to the
indemnifying party, (iii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party.  It is understood that the
indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel) for all such
indemnified parties and that all such fees and expenses shall be reimbursed as
they are incurred.  An indemnifying party will not, without the prior written
consent of the indemnified parties, settle or compromise or consent to the entry
of any judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

<PAGE>

            (d)    In the event that the indemnity provided in paragraph (a) or
(b) of this Section 6 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, then each applicable indemnifying party, in
lieu of indemnifying such indemnified party, shall have a joint and several
obligation to contribute to the aggregate losses, claims, damages and
liabilities (including legal or other expenses reasonably incurred in connection
with investigating or defending the same) (collectively "Losses") to which such
indemnified party may be subject in such proportion as is appropriate to reflect
the relative benefits received by such indemnifying party, on the one hand, and
such indemnified party, on the other hand, from the Initial Placement and the
Registration Statement that resulted in such Losses; PROVIDED, HOWEVER, that in
no case shall any Initial Purchaser or any subsequent Holder of any Note or
Exchange Note be responsible, in the aggregate, for any amount in excess of the
purchase discount or commission applicable to such Note, or in the case of an
Exchange Note, applicable to the Note that was exchangeable into such Exchange
Note, as set forth on the cover page of the Final Memorandum, nor shall any
underwriter be responsible for any amount in excess of the underwriting discount
or commission applicable to the Notes purchased by such underwriter under the
Registration Statement that resulted in such Losses.  If the allocation provided
by the immediately preceding sentence is unavailable for any reason, the
indemnifying party and the indemnified party shall contribute in such proportion
as is appropriate to reflect not only such relative benefits but also the
relative fault of such indemnifying party, on the one hand, and such indemnified
party, on the other hand, in connection with the statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
Benefits received by the Company shall be deemed to be equal to the total net
proceeds from the Initial Placement (before deducting expenses) as set forth on
the cover page of the Final Memorandum.  Benefits received by the Initial
Purchasers shall be deemed to be equal to the total purchase discounts and
commissions as set forth on the cover page of the Final Memorandum, and benefits
received by any other Holders shall be deemed to be equal to the value of
receiving Notes or Exchange Notes, as applicable, registered under the
Securities Act.  Benefits received by any underwriter shall be deemed to be
equal to the total underwriting discounts and commissions, as set forth on the
cover page of the Prospectus forming a part of the Registration Statement that
resulted in such Losses.  Relative fault shall be determined by reference to
whether any alleged untrue statement or omission relates to information provided
by the indemnifying party, on the one hand, or by the indemnified party, on the
other hand.  The parties agree that it would not be just and equitable if
contribution were determined by pro rata allocation or any other method of
allocation that did not take account of the equitable considerations referred to
above.  Notwithstanding the provisions of this paragraph (d), no person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  For purposes of this Section 6,
each person who controls a Holder within the meaning of either the Securities
Act or the Exchange Act and each director, officer, employee and agent of such
Holder shall have the same rights to contribution as such Holder, and each
person who controls the Company within the meaning of either the Securities Act
or the Exchange Act, each officer of the Company who shall have signed the
Registration Statement and each director of the

<PAGE>

Company shall have the same rights to contribution as the Company, subject in
each case to the applicable terms and conditions of this paragraph (d).

            (e)    The provisions of this Section 6 will remain in full force
and effect, regardless of any investigation made by or on behalf of any Holder
or the Company or any of the officers, directors or controlling persons referred
to in Section 6 hereof, and will survive the sale by a Holder of Notes covered
by a Registration Statement.

            7.     MISCELLANEOUS.

            (a)    NO INCONSISTENT AGREEMENT.  The Company has not, as of the
date hereof, entered into, nor shall it, on or after the date hereof, enter
into, any agreement that conflicts with the rights granted to the Holders herein
or otherwise conflicts with the provisions hereof.

            (b)    AMENDMENTS AND WAIVERS.  The provisions of this Agreement,
including the provisions of this sentence, may not be amended, qualified,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given, unless the Company has obtained the written
consent of the Holders of at least a majority of the then outstanding aggregate
principal amount of Notes (or, after the consummation of any Exchange Offer in
accordance with Section 2 hereof, of Exchange Notes); PROVIDED that, with
respect to any matter that directly or indirectly affects the rights of the
Initial Purchasers hereunder, the Company shall obtain the written consent of
the Initial Purchasers.  Notwithstanding the foregoing (except the foregoing
proviso), a waiver or consent to departure from the provisions hereof with
respect to a matter that relates exclusively to the rights of Holders whose
Notes are being sold pursuant to a Registration Statement and that does not
directly or indirectly affect the rights of other Holders may be given by the
Majority Holders, determined on the basis of Notes being sold rather than
registered under such Registration Statement.

            (c)    NOTICES.  All notices and other communications provided for
or permitted hereunder shall be made in writing by hand-delivery, first-class
mail, telex, telecopier, or air courier guaranteeing overnight delivery:

            (i)    if to a Holder, at the most current address given by such
     Holder to the Company in accordance with the provisions of this Section
     7(c), which address initially is, with respect to each Holder, the address
     of such Holder maintained by the Registrar under the Indenture, with a copy
     in like manner to NationsBanc Montgomery Securities LLC;

            (ii)   if to the Initial Purchasers, at NationsBanc Montgomery
     Securities LLC, 767 Fifth Avenue, Floor 12A, New York, New York 10153,
     Attention: Paul Jetter; and

            (iii)   if to the Company, Dobson/Sygnet Operating Company, 13439 N.
     Broadway Extension, Suite 200, Oklahoma City, Oklahoma 73114, Attention:
     Bruce R.

     Knoohuizen, with a copy to McAfee & Taft A Professional Corporation, 211
     North Robinson, Suite 1000, Oklahoma City, Oklahoma 73102, Attention:
     Theodore M. Elam and W. Christopher Coleman.

            All such notices and communications shall be deemed to have been
duly given when received.  The Initial Purchasers, on the one hand, or the
Company, on the other, by notice to the other party or parties may designate
additional or different addresses for subsequent notices or communications.

            (d)    SUCCESSORS AND ASSIGNS.  This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the
parties, including, without the need for an express assignment or any consent by
the Company thereto, subsequent Holders of Notes and/or Exchange Notes.  The
Company hereby agrees to extend the benefits of this Agreement to any Holder of
Notes and/or Exchange Notes and any such Holder may specifically enforce the
provisions of this Agreement as if an original party hereto.

            (e)    COUNTERPARTS.  This Agreement may be executed in any number
of counterparts and by the 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.

            (f)    HEADINGS.  The headings in this Agreement are for convenience
of reference only and shall not limit or otherwise affect the meaning hereof.

            (g)    GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

            (h)    SEVERABILITY.  In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstances, is
held invalid, illegal or unenforceable in any respect for any reason, the
validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions hereof shall not be in any way impaired
or affected thereby, it being intended that all of the rights and privileges of
the parties shall be enforceable to the fullest extent permitted by law.
            (i)    NOTES HELD BY THE COMPANY, ETC.  Whenever the consent or
approval of Holders of a specified percentage of principal amount of Notes or
Exchange Notes is required hereunder, Notes or Exchange Notes, as applicable,
held by the Company or its Affiliates (other than subsequent Holders of Notes or
Exchange Notes if such subsequent Holders are deemed to be Affiliates solely by
reason of their holdings of such Notes or Exchange Notes) shall not be counted
in determining whether such consent or approval was given by the Holders of such
required percentage.

     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes.  The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the

supplemented from time to time, may be used by a broker-dealer in connection
with resales of Exchange Notes received in exchange for Notes where such Notes
were acquired by such broker-dealer as a result of market-making activities or
other trading activities.  The Company has agreed that, starting on the
Expiration Date (as defined herein) and ending on the close of business one year
after the Expiration Date, it will make this Prospectus available to any
broker-dealer for use in connection with any such resale.  See "Plan of
Distribution."

     Each broker-dealer that receives Exchange Notes for its own account in

     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be used

the Expiration Date and ending on the close of business one year after the
Expiration Date, it will make this Prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale. In
addition, until such date all dealers effecting transactions in the Exchange
Notes may be required to deliver a prospectus.

                minimum amount of at least $3,000,000 (other than prepayment of
                Swing Line Borrowings which may be in integral multiples of
                $250,000) or a greater integral multiple of $1,000,000 thereof;
                (iii) any Eurodollar Rate Borrowing may only be prepaid at the
                end of an applicable Interest Period; and (iv) Borrower shall
                pay any related Consequential Loss within ten (10) days after
                demand therefor.  Each notice of prepayment shall specify the

                Type of Borrowing(s) and amount(s) of such Borrowing(s) to be
                prepaid and shall constitute a binding obligation of Borrower to
                make a prepayment on the date stated therein, together with
                (unless such prepayment is made with respect to a Base Rate

                Subfacility) accrued and unpaid interest to the date of such
                payment on the aggregate principal amount prepaid.  Unless a

                or prepayment of the Revolver Principal Debt or Swing Line 
                Principal Debt may be reborrowed by Borrower, subject to the 
                terms and conditions hereof.

                        (ii)    After giving Administrative Agent advance
                written notice of the intent to prepay, Borrower may voluntarily
                prepay all or any part of the Term Loan C Principal Debt from
                time to time; PROVIDED THAT: (i) such notice must be received by
                Administrative Agent by 12:00 noon Dallas, Texas time on the
                third Business Day preceding the date of prepayment; (ii) each
                such partial prepayment must be in a minimum amount of at least
                $5,000,000 or a greater integral multiple of $1,000,000 thereof;

                prior to December 31, 2000, Borrower shall pay a redemption

                for prepayments made from the Closing Date to December 31, 1999;
                and (B) 1% of the principal amount of the Term Loan C Principal
                Debt being prepaid for prepayments being made on or after

                prepayment shall specify the prepayment date, and the amount to
                be prepaid and shall constitute a binding obligation of Borrower
                to make a prepayment on the date stated therein, together with
                the applicable redemption premium and all accrued and unpaid
                interest to the date of such prepayment on the aggregate

                (b)     MANDATORY PREPAYMENTS FROM NET CASH PROCEEDS.  Until
        such time as the Principal Debt has been repaid in full, the Revolver
        Commitment and the Principal Debt shall be permanently reduced or
        prepaid, as the case may be, in the amounts and upon the occurrence of
        the following events:

                        (i)     Concurrently with any Debt Issuance by Borrower,
                the Revolver Commitment and the Principal Debt shall be
                permanently reduced or prepaid, as the case may be, by an amount
                equal to 100% of the Net Cash Proceeds realized by Borrower from
                such Debt Issuance;

                        (ii)    Concurrently with the consummation of any
                Significant Sale by any Company (which Significant Sale must be
                otherwise permitted under the Loan Papers or shall have been
                consented to by Required Lenders), the Revolver Commitment and
                the Principal Debt shall be permanently reduced or prepaid, as
                the case may be, in the order and manner specified herein, by an
                amount equal to 100% of the Net Cash Proceeds in excess of
                $3,000,000 realized by any Company from such Significant Sale
                (or if such disposition is a Significant Sale as a result of
                aggregation with other asset dispositions in the same fiscal
                year, 100% of the aggregate Net Cash Proceeds received from all
                such asset dispositions in the calendar year in excess of
                $3,000,000), if such Net Cash Proceeds or any portion thereof
                have not been reinvested in similar assets of the Companies
                within eleven (11) months from the date of consummation of such
                Significant Sale or other asset disposition, as the case may be;

                        (iii)   Concurrently with any Equity Issuance by
                Borrower, the Revolver Commitment and the Principal Debt shall
                be permanently reduced or prepaid, as the case

                may be, in the order and manner specified herein, by an amount 
                equal to 100% of the Net Cash Proceeds realized by Borrower from
                such Equity Issuance;

        Each commitment reduction or prepayment under this SECTION 2.7(b) shall
        be applied ratably to the Revolver Commitment and the Term Principal
        Debt (for purposes hereof, "RATABLY", for each Facility, on any date of
        determination, shall mean the proportion that either the Revolver
        Commitment or the Term Principal Debt under the applicable Term Loan
        Facility, as the case may be, bears to the SUM of the Revolver
        Commitment and the Term Principal Debt).

                (c)     MANDATORY PREPAYMENTS FROM EXCESS CASH FLOW.  Borrower
        shall, no later than the thirtieth (30th) day following the date on
        which it delivers the Financial Statements required under SECTION 9.3(a)
        for fiscal year 1999 and each fiscal year thereafter, (but in any event
        within 120 days after the end of Borrower's fiscal year), prepay an
        aggregate principal amount equal to either (i) 75% of Excess Cash Flow
        for the fiscal year covered by such Financial Statements, if the
        Leverage Ratio of the Companies is greater than 4.0:1.0 or (ii) 50% of
        Excess Cash Flow for the fiscal year covered by such Financial
        Statements, if the Leverage Ratio of the Companies is less than or equal
        to 4.0:1.0.  Each reduction or prepayment under this SECTION 2.7(c)
        shall be applied ratably to the Revolver Commitment, the Term Loan A
        Principal Debt, and the Term Loan B Principal Debt, or if no Term Loan A
        Principal Debt or Term Loan B Principal Debt remains outstanding, then
        to the Term Loan C Principal Debt (for purposes hereof, "RATABLY," for
        each Facility, on any date of determination, shall mean the proportion
        that the Revolver Commitment or the Term Principal Debt under the
        applicable Term Loan Facility, as the case may be, bears to the SUM of
        the Revolver Commitment and the aggregate Term Principal Debt under the
        applicable Term Facilities being prepaid).  Amounts prepaid pursuant to
        this SECTION 2.7(c), shall not reduce the Revolver Commitment unless (i)
        a Default or Potential Default then exists, or (ii) no Term Loan
        Principal Debt is then outstanding. 

                (d)     MANDATORY PREPAYMENTS FROM EXCESS TOWER PROCEEDS. Upon
        consummation of the Dobson Tower Resale, Borrower shall, concurrently
        with its receipt of any Excess Tower Proceeds, ratably prepay the Term
        Loan A Principal Debt and the Term Loan B Principal Debt, in an amount
        equal to 100% of the Excess Tower Proceeds.  Each reduction or
        prepayment under this SECTION 2.7(d) shall be applied ratably to the
        Term Loan A Principal Debt and the Term Loan B Principal Debt (for
        purposes of this CLAUSE (d), "RATABLY," on any date of determination,
        shall mean the proportion that either the Term Loan A Principal Debt or
        the Term Loan B Principal Debt bears to the SUM of the Term Loan A
        Principal Debt and the Term Loan B Principal Debt).

                (e)     MANDATORY PREPAYMENTS FROM COMMITMENT REDUCTION.  On any
        Business Day that either (i) the Revolver Commitment Usage exceeds the
        Revolver Commitment or (ii) the Swing Line Principal Debt exceeds the
        Swing Line Commitment, Borrower shall prepay the Revolving Principal
        Debt or the Swing Line Principal Debt, as the case may be, in an amount
        equal to such excess.

                (f)     TERM LOAN OPT-OUTS.

                        (i)      TERM LOAN B.  To the extent there is any
                Revolver Commitment or Term Loan A Principal Debt outstanding,
                any Term Loan B Lender, at its option, may elect not to accept
                such partial prepayment under this SECTION 2.7 (other than
                SECTION 2.7(d)) (such Lender being a "DECLINING B LENDER"), in
                which event the provisions of the next sentence shall apply.  On
                the prepayment date, an amount equal to that portion of the
                prepayment

                amount available to prepay Term Loan B Lenders (less any amounts
                that would otherwise be payable to Declining B Lenders) shall 
                be applied ratably to prepay Term Loan B Principal Debt owed 
                to Term Loan B Lenders other than Declining B Lenders and any 
                amounts that would otherwise have been applied to prepay Term 
                Loan B Principal Debt owing to Declining B Lenders shall 
                instead be applied ratably to prepay the remaining Term Loan A 
                Principal Debt and reduce the Revolver Commitment as provided 
                in SECTIONS 2.7(b) through 2.7(f); PROVIDED FURTHER, that upon 
                prepayment in full of the Term Loan B Principal Debt owing to 
                Term Loan B Lenders other than Declining B Lenders the remainder
                of any prepayment amount that is to be applied to Term Loan B 
                Principal Debt shall be applied ratably to prepay Term Loan B 
                Principal Debt owing to Declining B Lenders.  Any Term Loan B 
                Lender may elect not to accept its ratable share of a partial 
                prepayment by giving written notice to the Administrative Agent 
                not later than 11:00 a.m. Dallas, Texas time on the Business 
                Day immediately preceding the scheduled prepayment date.

                        (ii)    TERM LOAN C.  To the extent there is any
                Revolver Commitment, Term Loan A Principal Debt, or Term Loan B
                Principal Debt outstanding, any Term Loan C Lender, at its
                option, may elect not to accept such partial prepayment under
                this SECTION 2.7 (other than SECTION 2.7(d)) (such Lender being
                a "DECLINING C LENDER"), in which event the provisions of the
                next sentence shall apply.  On the prepayment date, an amount
                equal to that portion of the prepayment amount available to
                prepay Term Loan C Lenders (less any amounts that would
                otherwise be payable to Declining C Lenders) shall be applied
                ratably to prepay Term Loan C Principal Debt owed to Term Loan C
                Lenders other than Declining C Lenders and any amounts that
                would otherwise have been applied to prepay Term Loan C
                Principal Debt owing to Declining C Lenders shall instead be
                applied ratably to prepay the remaining Term Loan A Principal
                Debt and Term Loan B Principal Debt, and reduce the Revolver
                Commitment as provided in SECTIONS 2.7(b) through 2.7(f);
                PROVIDED FURTHER, that upon prepayment in full of Term Loan C
                Principal Debt owing to Term Loan C Lenders other than Declining
                C Lenders the remainder of any prepayment amount that is to be
                applied to Term Loan C Principal Debt shall be applied ratably
                to prepay Term Loan C Principal Debt owing to Declining C
                Lenders.  Any Term Loan C Lender may elect not to accept its
                ratable share of a partial prepayment by giving written notice
                to the Administrative Agent not later than 11:00 a.m. Dallas,
                Texas time on the Business Day immediately preceding the
                scheduled prepayment date.

                (g)     MANDATORY PREPAYMENTS OF INTEREST/CONSEQUENTIAL LOSS. 
        All prepayments under this SECTION 2.7 shall be made, together with
        accrued interest to the date of such prepayment on the principal amount
        prepaid, together with any Consequential Loss arising as a result
        thereof.

                (h)     APPLICATION OF REVOLVER COMMITMENT REDUCTION.   All
        Revolver Commitment reductions hereunder shall be applied ratably to
        each Revolver Lender's Committed Sum under the Revolver Facility and
        shall be applied to the regularly scheduled Revolver Commitment
        reductions under SECTION 3.2(c) in inverse order of maturities; PROVIDED
        THAT, (i) if there is no Default or Potential Default, no mandatory
        commitment reduction under SECTION 2.7(b) (including any amount of
        reduction from a prepayment under SECTION 2.7(b) that is applied to the
        Revolver Commitment as a result of the opt-out provisions in
        SECTION 2.7(f)) shall reduce the Revolver Commitment to an amount equal
        to the lesser of $10,000,000 or the Revolver Commitment then outstanding
        except in the event of the repayment in full of the Obligation; (ii) if
        any Revolver Commitment reductions

        are not made as a result of CLAUSE (i) preceding, then the amount of 
        such mandatory prepayment not applied as a Revolver Commitment reduction
        shall be applied to the Term Loan A Principal Debt until paid in full, 
        then to the Term Loan B Principal Debt until paid in full, and then to 
        the Term Loan C Principal Debt until paid in full; and (iii) if required
        pursuant to SECTION 2.7(e) Borrower shall also make a mandatory 
        prepayment of the Revolver Principal Debt, TOGETHER WITH (x) all 
        accrued and unpaid interest on the principal amount so prepaid and (y) 
        any Consequential Loss arising as a result thereof.

                (i)     APPLICATION OF MANDATORY PREPAYMENTS OF TERM PRINCIPAL
        DEBT.  All mandatory prepayments of the term Principal Debt under any
        Term Facility shall be applied ratably to each Term Lender's Committed
        Sum under such Term Facility and shall be applied to the 
        regularly-scheduled Term Principal Debt reductions for such Term 
        Facility as set forth in SECTION 3.2(d), (e), or (f) (as the case 
        may be) in inverse order of maturities.

        2.8     BORROWING PROCEDURE.  The following procedures apply to all 
Borrowings (other than a Swing Line Borrowing):

                (a)     Each Borrowing shall be made on Borrower's notice (a
        "NOTICE OF BORROWING," substantially in the form of EXHIBIT B-1) to
        Administrative Agent requesting that Lenders fund a Borrowing on a
        certain date (the "BORROWING DATE"), which notice (i) shall be
        irrevocable and binding on Borrower, (ii) shall specify if it is for a
        Borrowing under the Revolver Facility, Term Loan A, Term Loan B, or Term
        Loan C, (iii) shall specify the Borrowing Date, amount, Type, and (for a
        Borrowing comprised of Eurodollar Rate Borrowings) Interest Period, and
        (iv) must be received by Administrative Agent no later than 10:00 a.m.
        Dallas, Texas time on the third Business Day preceding the Borrowing
        Date for any Eurodollar Rate Borrowing or on the Business Day
        immediately preceding the Borrowing Date for any Base Rate Borrowing. 
        Administrative Agent shall timely notify each Lender with respect to
        each Notice of Borrowing.

                (b)     Each Lender shall remit its Pro Rata Part for the
        relevant Facility of each requested Borrowing to Administrative Agent's
        principal office in Dallas, in funds which are or will be available for
        immediate use by Administrative Agent by 1:00 p.m. Dallas time on the
        Borrowing Date therefor.  Subject to receipt of such funds,
        Administrative Agent shall (unless to its actual knowledge any of the
        conditions precedent therefor have not been satisfied by Borrower or
        waived by Required Lenders) make such funds available to Borrower by
        causing such funds to be deposited to Borrower's account as designated
        to Administrative Agent by Borrower.  Notwithstanding the foregoing,
        unless Administrative Agent shall have been notified by a Lender prior
        to a Borrowing Date that such Lender does not intend to make available
        to Administrative Agent such Lender's Pro Rata Part of the applicable
        Borrowing, Administrative Agent may assume that such Lender has made
        such proceeds available to Administrative Agent on such date, as
        required herein, and Administrative Agent may (unless to its actual
        knowledge any of the conditions precedent therefor have not been
        satisfied by Borrower or waived by Required Lenders), in reliance upon
        such assumption (but shall not be required to), make available to
        Borrower a corresponding amount in accordance with the foregoing terms,
        but, if such corresponding amount is not in fact made available to
        Administrative Agent by such Lender on such Borrowing Date,
        Administrative Agent shall be entitled to recover such corresponding
        amount on demand (i) from such Lender, together with interest at the
        Federal Funds Rate during the period commencing on the date such
        corresponding amount was made available to Borrower and ending on (but
        excluding) the date Administrative Agent recovers such corresponding
        amount from such 

                                      31

<PAGE>

        Lender, or (ii) if such Lender fails to pay such corresponding amount 
        forthwith upon such demand, then from Borrower, TOGETHER WITH interest 
        at a rate per annum equal to the applicable rate for such Borrowing 
        during the period commencing on such Borrowing Date and ending on 
        (but excluding) the date Administrative Agent recovers such 
        corresponding amount from Borrower.  No Lender shall be responsible
        for the failure of any other Lender to make its Pro Rata Part of any
        Borrowing.

SECTION 3       TERMS OF PAYMENT.

        3.1     LOAN ACCOUNTS, NOTES, AND PAYMENTS.

                (a)     The Revolver Principal Debt (other than Swing Line
        Principal Debt) owed to each Revolver Lender shall be evidenced by the
        Revolver Notes, one payable to each Revolver Lender in the maximum
        stated principal amount of its Committed Sum under the Revolver Facility
        as of the Closing Date.  The Swing Line Principal Debt shall be

                (g)     On any date of determination if the Revolver Commitment
        Usage exceeds the  Revolver Commitment or the Swing Line Principal Debt
        exceeds the Swing Line Commitment then in effect, then Borrower shall
        make a mandatory prepayment of the Principal Debt under the Revolver
        Facility or the Swing Line Subfacility, respectively, in at least the
        amount of such excess, TOGETHER WITH (x) all accrued and unpaid interest
        on the principal amount so prepaid and (y) any Consequential Loss
        arising as a result thereof.  All mandatory prepayments hereunder shall
        be applied Pro Rata to each Revolver Lender's Committed Sum and shall be
        applied to the regularly-scheduled Commitment reductions hereunder in
        inverse order of maturity.

        3.3     INTEREST OPTIONS.  Except where specifically otherwise 
provided, Borrowings shall bear interest at a rate per annum equal to the 
LESSER OF (a) as to the respective Type of Borrowing (as designated by 
Borrower in accordance with this Agreement), the Base Rate plus the 
Applicable Margin for Base Rate Borrowings or the Adjusted Eurodollar Rate 
plus the Applicable Margin for Eurodollar Rate Borrowings, AND (b) the 
Maximum Rate.  Each change in the Base Rate or the Maximum Rate, subject to 
the terms of this Agreement, will become effective, without notice to 
Borrower or any other Person, upon the effective date of such change.

        3.4     QUOTATION OF RATES.  It is hereby acknowledged that a 
Responsible Officer or other appropriately designated officer of Borrower may 
call Administrative Agent on or before the date on which a Notice of 
Borrowing is to be delivered by Borrower in order to receive an indication of 
the rates then in effect, but such indicated rates shall neither be binding 
upon Administrative Agent or Lenders nor affect the rate of interest which 
thereafter is actually in effect when the Notice of Borrowing is given.

        3.5     DEFAULT RATE.  At the option of Required Lenders and to the 
extent permitted by Law, all past-due Principal Debt and accrued interest 
thereon shall bear interest from maturity (stated or by acceleration) at the 
Default Rate until paid, regardless whether such payment is made before or 
after entry of a judgment.

        3.6     INTEREST RECAPTURE.  If the designated rate applicable to any 
Borrowing exceeds the Maximum Rate, the rate of interest on such Borrowing 
shall be limited to the Maximum Rate, but any subsequent reductions in such 
designated rate shall not reduce the rate of interest thereon below the 
Maximum Rate until the total amount of interest accrued thereon equals the 
amount of interest which would have accrued thereon if such designated rate 
had at all times been in effect.  In the event that at maturity (stated or by 
acceleration), or at final payment of the Principal Debt, the total amount of 
interest paid or accrued is less than the amount of interest which would have 
accrued if such designated rates had at all times been in effect, then, at 
such time and to the extent permitted by Law, Borrower shall pay an amount 
equal to the difference between (a) the LESSER OF the amount of interest 
which would have accrued if such designated rates had at all times been in 
effect AND the amount of interest which would have accrued if the Maximum 
Rate had at all times been in effect, and (b) the amount of interest actually 
paid or accrued on the Principal Debt.

        3.7     INTEREST CALCULATIONS.

                (a)     All payments of interest shall be calculated on the
        basis of actual number of days (including the first day but excluding
        the last day) elapsed but computed as if each calendar year consisted of
        360 days in the case of a Eurodollar Rate Borrowing (unless such
        calculation would result in the interest on the Borrowings exceeding the
        Maximum Rate, in which event such interest shall be calculated on the
        basis of a year of 365 or 366 days, as the case may be), and 365 or 

                                      36
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

        366 days, as the case may be, in the case of a Base Rate Borrowing.  
        All interest rate determinations and calculations by Administrative 
        Agent shall be conclusive and binding absent manifest error.

                (b)     The provisions of this Agreement relating to the
        calculation of the Base Rate and the Adjusted Eurodollar Rate are
        included only for the purpose of determining the rate of interest or
        other amounts to be paid hereunder that are based upon such rate.

        3.8     MAXIMUM RATE.  Regardless of any provision contained in any 
Loan Paper, neither Administrative Agent nor any Lender shall ever be 
entitled to contract for, charge, take, reserve, receive, or apply, as 
interest on the Obligation, or any part thereof, any amount in excess of the 
Maximum Rate, and, if Lenders ever do so, then such excess shall be deemed a 
partial prepayment of principal and treated hereunder as such and any 
remaining excess shall be refunded to Borrower.  In determining if the 
interest paid or payable exceeds the Maximum Rate, Borrower and Lenders 
shall, to the maximum extent permitted under applicable Law, (a) treat all 
Borrowings as but a single extension of credit (and Lenders and Borrower 
agree that such is the case and that provision herein for multiple Borrowings 
is for convenience only), (b) characterize any nonprincipal payment as an 
expense, fee, or premium rather than as interest, (c) exclude voluntary 
prepayments and the effects thereof, and (d) amortize, prorate, allocate, and 
spread the total amount of interest throughout the entire contemplated term 
of the Obligation; PROVIDED THAT, if the Obligation is paid and performed in 
full prior to the end of the full contemplated term thereof, and if the 
interest received for the actual period of existence thereof exceeds the 
Maximum Amount, Lenders shall refund such excess, and, in such event, Lenders 
shall not, to the extent permitted by Law, be subject to any penalties 
provided by any Laws for contracting for, charging, taking, reserving, or 
receiving interest in excess of the Maximum Amount.

        3.9     INTEREST PERIODS.  When Borrower requests any Eurodollar Rate 
Borrowing, Borrower may elect the interest period (each an "INTEREST PERIOD") 
applicable thereto, which shall be, at Borrower's option, one, two, three, or 
six months (or other periods, if requested by Borrower and available from the 
Lenders); PROVIDED, HOWEVER, that: (a) the initial Interest Period for a 
Eurodollar Rate Borrowing shall commence on the date of such Borrowing 
(including the date of any conversion thereto), and each Interest Period 
occurring thereafter in respect of such Borrowing shall commence on the day 
on which the next preceding Interest Period applicable thereto expires; (b) 
if any Interest Period for a Eurodollar Rate Borrowing begins on a day for 
which there is no numerically corresponding Business Day in the calendar 
month at the end of such Interest Period, such Interest Period shall end on 
the next Business Day immediately following what otherwise would have been 
such numerically corresponding day in the calendar month at the end of such 
Interest Period (UNLESS such date would be in a different calendar month from 
what would have been the month at the end of such Interest Period, or UNLESS 
there is no numerically corresponding day in the calendar month at the end of 
the Interest Period; whereupon, such Interest Period shall end on the last 
Business Day in the calendar month at the end of such Interest Period); (c) 
no Interest Period may be chosen with respect to any portion of the Principal 
Debt which would extend beyond the scheduled repayment date (including any 
dates on which mandatory prepayments are required to be made) for such 
portion of the Principal Debt; and (d) no more than an aggregate of eight (8) 
Interest Periods shall be in effect at one time.

        3.10    CONVERSIONS.  For Borrowings under the Revolver Facility, 
Term Loan A, or Term Loan B, Borrower may (a) convert a Eurodollar Rate 
Borrowing on the last day of an Interest Period to a Base Rate Borrowing, (b) 
convert a Base Rate Borrowing at any time to a Eurodollar Rate Borrowing, and 
(c) elect a new Interest Period (in the case of a Eurodollar Rate Borrowing), 
by giving notice (a "NOTICE OF CONVERSION," substantially in the form of 
EXHIBIT B-2) of such intent no later than 10:00 a.m. Dallas, 

                                      37
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

Texas time on the third Business Day prior to the date of conversion or the 
last day of the Interest Period, as the case may be (in the case of a 
conversion to a Eurodollar Rate Borrowing or an election of a new Interest 
Period), and no later than 10:00 a.m. Dallas, Texas time one Business Day 
prior to the last day of the Interest Period (in the case of a conversion to 
a Base Rate Borrowing); PROVIDED THAT, the principal amount converted to, or 
continued as, a Eurodollar Rate Borrowing shall be in an amount not less than 
$5,000,000 or a greater integral multiple of $1,000,000. Administrative Agent 
shall timely notify each Lender with respect to each Notice of Conversion.  
Absent Borrower's Notice of Conversion or election of a new Interest Period, 
a Eurodollar Rate Borrowing shall be deemed converted to a Base Rate 
Borrowing effective as of the expiration of the Interest Period applicable 
thereto.  No Eurodollar Rate Borrowing may be either made or continued as a 
Eurodollar Rate Borrowing, and no Base Rate Borrowing may be converted to a 
Eurodollar Rate Borrowing, if the interest rate for such Eurodollar Rate 
Borrowing would exceed the Maximum Rate.  The right to convert from a Base 
Rate Borrowing to a Eurodollar Rate Borrowing, or to continue as a Eurodollar 
Rate Borrowing, shall not be available during the occurrence of a Default or 
a Potential Default.

        3.11    ORDER OF APPLICATION.

                (a)     Payments and prepayments of the Obligation shall be
        applied in the order and manner specified in this Agreement; PROVIDED,
        HOWEVER, if no order is otherwise specified and no Default or Potential
        Default has occurred and is continuing, payments and prepayments of the
        Obligation shall be applied first to fees, second to accrued interest
        then due and payable on the Principal Debt, and then to the remaining
        Obligation in the order and manner as Borrower may direct.

                (b)     If a Default or Potential Default has occurred and is
        continuing (or if Borrower fails to give directions as permitted under
        SECTION 3.11(a)), any payment or prepayment (including proceeds from the
        exercise of any Rights) shall be applied to the Obligation in the
        following order:  (i) to the ratable payment of all fees, expenses, and
        indemnities for which Agents or Lenders have not been paid or reimbursed
        in accordance with the Loan Papers (as used in this SECTION 3.11(b)(i),
        a "RATABLE PAYMENT" for any Lender or any Agent shall be, on any date of
        determination, that proportion which the portion of the total fees,
        expenses, and indemnities owed to such Lender or such Agent bears to the
        total aggregate fees and indemnities owed to all Lenders and Agents on
        such date of determination); (ii) to the ratable payment of accrued and
        unpaid interest on the Revolver Principal Debt and the Term Principal
        Debt (as used in this SECTION 3.11(b)(ii), "RATABLE PAYMENT" means, for
        any Revolver Lender or Term Lender, on any date of determination, that
        proportion which the accrued and unpaid interest on the Revolver
        Principal Debt or the Term Principal Debt (as the case may be) owed to
        such Revolver Lender or Term Lender bears to the total accrued and
        unpaid interest under the Loan Papers owed to all Revolver Lenders and
        all Term Lenders); (iii) to the ratable payment of the Revolver
        Principal Debt and the Term Principal Debt (as used in this
        SECTION 3.11(b)(iii), "RATABLE PAYMENT" means for any Revolver Lender or
        any Term Lender, on any date of determination, that proportion which the
        Revolver Principal Debt or the Term Principal Debt (as the case may be)
        owed to such Revolver Lender or Term Lender bears to the sum of the
        Principal Debt and the Term Principal Debt owed to all Revolver Lenders
        and all Term Lenders; and (iv) to the payment of the remaining
        Obligation in the order and manner Required Lenders deem appropriate.

Subject to the provisions of SECTION 12 and provided that Administrative Agent
shall not in any event be bound to inquire into or to determine the validity,
scope, or priority of any interest or entitlement of any 

                                      38
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

Revolver Lender or Term Lender and may suspend all payments or seek 
appropriate relief (including, without limitation, instructions from Required 
Lenders or an action in the nature of interpleader) in the event of any doubt 
or dispute as to any apportionment or distribution contemplated hereby, 
Administrative Agent shall promptly distribute such amounts to each Lender in 
accordance with the Agreement and the related Loan Papers. 

        3.12    SHARING OF PAYMENTS, ETC.  If any Lender shall obtain any 
payment (whether voluntary, involuntary, or otherwise, including, without 
limitation, as a result of exercising its Rights under SECTION 3.13) which is 
in excess of its ratable share of any such payment (except as provided herein 
with respect to the Term Facility opt-outs in SECTION 2.7(f)), such Lender 
shall purchase from the other Revolver Lenders and the Term Lenders such 
participations as shall be necessary to cause such purchasing Lender to share 
the excess payment ratably with each of them; PROVIDED, HOWEVER, that if all 
or any portion of such excess payment is thereafter recovered from such 
purchasing Lender, the purchase shall be rescinded and the purchase price 
restored to the extent of such recovery.  Borrower agrees that any Lender so 
purchasing a participation from another Revolver Lender or Term Lender 
pursuant to this Section may, to the fullest extent permitted by Law, 
exercise all of its Rights of payment (including the Right of offset) with 
respect to such participation as fully as if such Revolver Lender or Term 
Lender were the direct creditor of Borrower in the amount of such 
participation.

        3.13    OFFSET.  Upon the occurrence and during the continuance of a 
Default, each Lender shall be entitled to exercise (for the benefit of all 
Revolver Lenders and Term Lenders in accordance with SECTION 3.12) the Rights 
of offset and/or banker's Lien against each and every account and other 
property, or any interest therein, which any Company may now or hereafter 
have with, or which is now or hereafter in the possession of, such Lender to 
the extent of the full amount of the Obligation.

        3.14    BOOKING BORROWINGS.  To the extent permitted by Law, any 
Lender may make, carry, or transfer its Borrowings at, to, or for the account 
of any of its branch offices or the office of any of its Affiliates; PROVIDED 
THAT, no Affiliate shall be entitled to receive any greater payment under 
SECTION 4 than the transferor Lender would have been entitled to receive with 
respect to such Borrowings.

SECTION 4       CHANGE IN CIRCUMSTANCES.

        4.1     INCREASED COST AND REDUCED RETURN.

                (a)     If, after the date hereof, the adoption of any
        applicable Law or any change in any applicable Law or any change in the
        interpretation or administration thereof by any Governmental Authority,
        or compliance by any Lender (or its Applicable Lending Office) with any
        request or directive (whether or not having the force of law) of any
        such Governmental Authority:

                        (i)     shall subject such Lender (or its Applicable
                Lending Office) to any Tax or other charge with respect to any
                Eurodollar Rate Borrowing, its Notes, or its obligation to loan
                Eurodollar Rate Borrowings, or change the basis of taxation of
                any amounts payable to such Lender (or its Applicable Lending
                Office) under this Agreement or its Notes in respect of any
                Eurodollar Rate Borrowings (other than taxes imposed on the
                overall net income of such Lender by the jurisdiction in which
                such Lender has its principal office or such Applicable Lending
                Office);

                        (ii)    shall impose, modify, or deem applicable any
                reserve, special deposit, assessment, or similar requirement
                (other than the Reserve Requirement utilized in the

                                      39

<PAGE>

                determination of the Adjusted Eurodollar Rate) relating to any
                extensions of credit or other assets of, or any deposits with or
                other liabilities or commitments of, such Lender (or its
                Applicable Lending Office), including the commitment of such
                Lender hereunder; or

                        (iii)   shall impose on such Lender (or its Applicable
                Lending Office) or the London interbank market any other
                condition affecting this Agreement or its Notes or any of such
                extensions of credit or liabilities or commitments;

        and the result of any of the foregoing is to increase the cost to such
        Lender (or its Applicable Lending Office) of making, converting into,
        continuing, or maintaining any Eurodollar Rate Borrowings or to reduce
        any sum received or receivable by such Lender (or its Applicable Lending
        Office) under this Agreement or its Notes with respect to any Eurodollar
        Rate Borrowing, then Borrower shall pay to such Lender on demand such
        amount or amounts as will compensate such Lender for such increased cost
        or reduction.  If any Lender requests compensation by Borrower under
        this SECTION 4.1(a), Borrower may, by notice to such Lender (with a copy
        to Administrative Agent), suspend the obligation of such Lender to loan
        or continue Borrowings of the Type with respect to which such
        compensation is requested, or to convert Borrowings of any other Type
        into Borrowings of such Type, until the event or condition giving rise
        to such request ceases to be in effect (in which case the provisions of
        SECTION 4.4 shall be applicable); PROVIDED, THAT such suspension shall
        not affect the right of such Lender to receive the compensation so
        requested.

                (b)     If, after the date hereof, any Lender shall have
        determined that the adoption of any applicable Law regarding capital
        adequacy or any change therein or in the interpretation or
        administration thereof by any Governmental Authority charged with the
        interpretation or administration thereof, or any request or directive
        regarding capital adequacy (whether or not having the force of law) of
        any such Governmental Authority has or would have the effect of reducing
        the rate of return on the capital of such Lender or any corporation
        controlling such Lender as a consequence of such Lender's obligations
        hereunder to a level below that which such Lender or such corporation
        could have achieved but for such adoption, change, request, or directive
        (taking into consideration its policies with respect to capital
        adequacy), then from time to time upon demand Borrower shall pay to such
        Lender such additional amount or amounts as will compensate such Lender
        for such reduction.

                (c)     Each Lender shall promptly notify Borrower and
        Administrative Agent of any event of which it has knowledge, occurring
        after the date hereof, which will entitle such Lender to compensation
        pursuant to this Section and will designate a different Applicable
        Lending Office if such designation will avoid the need for, or reduce
        the amount of, such compensation and will not, in the judgment of such
        Lender, be otherwise disadvantageous to it.  Any Lender claiming
        compensation under this Section shall furnish to Borrower and
        Administrative Agent a statement setting forth the additional amount or
        amounts to be paid to it hereunder which shall be conclusive in the
        absence of manifest error.  In determining such amount, such Lender may
        use any reasonable averaging and attribution methods.

        4.2     LIMITATION ON TYPES OF LOANS.  If on or prior to the first 
day of any Interest Period for any Eurodollar Rate Borrowing:

                (a)     Administrative Agent determines (which determination
        shall be conclusive) that by reason of circumstances affecting the
        relevant market, adequate and reasonable means do not exist for
        ascertaining the Eurodollar Rate for such Interest Period; or

                                      40
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

                (b)     Required Lenders determine (which determination shall be
        conclusive) and notify Administrative Agent that the Adjusted Eurodollar
        Rate will not adequately and fairly reflect the cost to the Lenders of
        funding Eurodollar Rate Borrowings for such Interest Period;

then Administrative Agent shall give Borrower prompt notice thereof 
specifying the relevant amounts or periods, and so long as such condition 
remains in effect, the Lenders shall be under no obligation to fund 
additional Eurodollar Rate Borrowings, continue Eurodollar Rate Borrowings, 
or to convert Base Rate Borrowings into Eurodollar Rate Borrowings, and 
Borrower shall, on the last day(s) of the then current Interest Period(s) for 
the outstanding Eurodollar Rate Borrowings, either prepay such Borrowings or 
convert such Borrowings into Base Rate Borrowings in accordance with the 
terms of this Agreement.

        4.3     ILLEGALITY.  Notwithstanding any other provision of this 
Agreement, in the event that it becomes unlawful for any Lender or its 
Applicable Lending Office to make, maintain, or fund Eurodollar Rate 
Borrowings hereunder, then such Lender shall promptly notify Borrower thereof 
and such Lender's obligation to make or continue Eurodollar Rate Borrowings 
and to convert other Base Rate Borrowings into Eurodollar Rate Borrowings 
shall be suspended until such time as such Lender may again make, maintain, 
and fund Eurodollar Rate Borrowings (in which case the provisions of SECTION 
4.4 shall be applicable).

        4.4     TREATMENT OF AFFECTED LOANS.  If the obligation of any Lender 
to fund Eurodollar Rate Borrowings or to continue, or to convert Base Rate 
Borrowings into Eurodollar Rate Borrowings, shall be suspended pursuant to 
SECTIONS 4.1, 4.2, or 4.3 hereof, such Lender's Eurodollar Rate Borrowings 
shall be automatically converted into Base Rate Borrowings on the last day(s) 
of the then current Interest Period(s) for Eurodollar Rate Borrowings (or, in 
the case of a conversion required by SECTION 4.3 hereof, on such earlier date 
as such Lender may specify to Borrower with a copy to Administrative Agent) 
and, unless and until such Lender gives notice as provided below that the 
circumstances specified in SECTIONS 4.1, 4.2, or 4.3 hereof that gave rise to 
such conversion no longer exist:

                (a)     to the extent that such Lender's Eurodollar Rate
        Borrowings have been so converted, all payments and prepayments of
        principal that would otherwise be applied to such Lender's Eurodollar
        Rate Borrowings shall be applied instead to its Base Rate Borrowings;
        and

                (b)     all Borrowings that would otherwise be made or continued
        by such Lender as Eurodollar Rate Borrowings shall be made or continued
        instead as Base Rate Borrowings, and all Borrowings of such Lender that
        would otherwise be converted into Eurodollar Rate Borrowings shall be
        converted instead into (or shall remain as) Base Rate Borrowings.

If such Lender gives notice to Borrower (with a copy to Administrative Agent) 
that the circumstances specified in SECTIONS 4.1, 4.2, or 4.3 hereof that 
gave rise to the conversion of such Lender's Eurodollar Rate Borrowings 
pursuant to this SECTION 4.4 no longer exist (which such Lender agrees to do 
promptly upon such circumstances ceasing to exist) at a time when Eurodollar 
Rate Borrowings made by other Lenders are outstanding, such Lender's Base 
Rate Borrowings shall be automatically converted, on the first day(s) of the 
next succeeding Interest Period(s) for such outstanding Eurodollar Rate 
Borrowings, to the extent necessary so that, after giving effect thereto, all 
Eurodollar Rate Borrowings held by the Lenders and by such Lender are held 
pro rata (as to principal amounts, Types, and Interest Periods) in accordance 
with their respective Commitments.            

        4.5     COMPENSATION.  Upon the request of any Lender, Borrower shall 
pay to such Lender such amount or amounts as shall be sufficient (in the 
reasonable opinion of such Lender) to compensate it for any loss, cost, or 
expense (including loss of anticipated profits) incurred by it as a result of:

                                      41
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

                (a)     any payment, prepayment, or conversion of a Eurodollar
        Rate Borrowing for any reason (including, without limitation, the
        acceleration of the loan pursuant to SECTION 11.1) on a date other than
        the last day of the Interest Period for such Borrowing; or

                (b)     any failure by Borrower for any reason (including,
        without limitation, the failure of any condition precedent specified in
        SECTION 7.3 to be satisfied) to borrow, convert, continue, or prepay a
        Eurodollar Rate Borrowing on the date for such borrowing, conversion,
        continuation, or prepayment specified in the relevant notice of
        borrowing, prepayment, continuation, or conversion under this Agreement.

        4.6     TAXES.

                (a)     Any and all payments by Borrower to or for the account
        of any Lender or Administrative Agent hereunder or under any other Loan
        Paper shall be made free and clear of and without deduction for any and
        all present or future Taxes, EXCLUDING, in the case of each Lender and
        Administrative Agent, Taxes imposed on its income and franchise Taxes
        imposed on it by the jurisdiction under the Laws of which such Lender
        (or its Applicable Lending Office) or Administrative Agent (as the case
        may be) is organized, or any political subdivision thereof.  If Borrower
        shall be required by Law to deduct any Taxes from or in respect of any
        sum payable under this Agreement or any other Loan Paper to any Lender
        or Administrative Agent, (i) the sum payable shall be increased as
        necessary so that after making all required deductions (including
        deductions applicable to additional sums payable under this SECTION 4.6)
        such Lender or Administrative Agent receives an amount equal to the sum
        it would have received had no such deductions been made, (ii) Borrower
        shall make such deductions, (iii) Borrower shall pay the full amount
        deducted to the relevant taxation authority or other authority in
        accordance with applicable Law, and (iv) Borrower shall furnish to
        Administrative Agent, at its address listed in SCHEDULE 2.1, the
        original or a certified copy of a receipt evidencing payment thereof.

                (b)     In addition, Borrower agrees to pay any and all present
        or future stamp or documentary taxes and any other excise or property
        taxes or charges or similar levies which arise from any payment made
        under this Agreement or any other Loan Paper or from the execution or
        delivery of, or otherwise with respect to, this Agreement or any other
        Loan Paper (hereinafter referred to as "OTHER TAXES").

                (c)     Borrower agrees to indemnify each Lender and
        Administrative Agent for the full amount of Taxes and Other Taxes
        (including, without limitation, any Taxes or other Taxes imposed or
        asserted by any jurisdiction on amounts payable under this SECTION 4.6)
        paid by such Lender or Administrative Agent (as the case may be) and any
        liability (including penalties, interest, and expenses) arising
        therefrom or with respect thereto.  

                (d)     Each Lender organized under the Laws of a jurisdiction
        outside the United States, on or prior to the date of its execution and
        delivery of this Agreement in the case of each Lender listed on the
        signature pages hereof and on or prior to the date on which it becomes a
        Lender in the case of each other Lender, and from time to time
        thereafter if requested in writing by Borrower or Administrative Agent
        (but only so long as such Lender remains lawfully able to do so), shall
        provide Borrower and Administrative Agent with (i) INTERNAL REVENUE
        SERVICE FORM 1001 or 4224, as appropriate, or any successor form
        prescribed by the Internal Revenue Service, certifying that such Lender
        is entitled to benefits under an income tax treaty to which the United
        States is a party 

                                      42
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

        which reduces the rate of withholding tax on payments of interest or 
        certifying that the income receivable pursuant to this Agreement is 
        effectively connected with the conduct of a trade or business in the 
        United States, (ii) INTERNAL REVENUE SERVICE FORM W-8 or W-9, as 
        appropriate, or any successor form prescribed by the Internal Revenue 
        Service, and (iii) any other form or certificate required by any 
        taxing authority (including any certificate required by SECTIONS 871(h)
        and 881(c) of the Internal Revenue Code), certifying that such Lender is
        entitled to an exemption from or a reduced rate of tax on payments
        pursuant to this Agreement or any of the other Loan Papers.

                (e)     For any period with respect to which a Lender has failed
        to provide Borrower and Administrative Agent with the appropriate form
        pursuant to SECTION 4.6(d) (unless such failure is due to a change in
        Law occurring subsequent to the date on which a form originally was
        required to be provided), such Lender shall not be entitled to
        indemnification under SECTION 4.6(a) or 4.6(b) with respect to Taxes
        imposed by the United States; PROVIDED, HOWEVER, that should a Lender,
        which is otherwise exempt from or subject to a reduced rate of
        withholding tax, become subject to Taxes because of its failure to
        deliver a form required hereunder, Borrower shall take such steps as
        such Lender shall reasonably request to assist such Lender to recover
        such Taxes.

                (f)     If Borrower is required to pay additional amounts to or
        for the account of any Lender pursuant to this SECTION 4.6, then such
        Lender will agree to use reasonable efforts to change the jurisdiction
        of its Applicable Lending Office so as to eliminate or reduce any such
        additional payment which may thereafter accrue if such change, in the
        judgment of such Lender, is not otherwise disadvantageous to such
        Lender.

                (g)     Within thirty (30) days after the date of any payment of
        Taxes, Borrower shall furnish to Administrative Agent the original or a
        certified copy of a receipt evidencing such payment.

                (h)     Without prejudice to the survival of any other agreement
        of Borrower hereunder, the agreements and obligations of Borrower
        contained in this SECTION 4.6 shall survive the termination of the Total
        Commitment and the payment in full of the Obligation.

SECTION 5       FEES.

        5.1     TREATMENT OF FEES.  Except as otherwise provided by Law, the 
fees described in this SECTION 5: (a) do not constitute compensation for the 
use, detention, or forbearance of money, (b) are in addition to, and not in 
lieu of, interest and expenses otherwise described in this Agreement, (c) 
shall be payable in accordance with SECTION 3.1, (d) shall be non-refundable, 
(e) shall, to the fullest extent permitted by Law, bear interest, if not paid 
when due, at the Default Rate, and (f) shall be calculated on the basis of 
actual number of days (including the first day but excluding the last day) 
elapsed, but computed as if each calendar year consisted of 360 days, unless 
such computation would result in interest being computed in excess of the 
Maximum Rate in which event such computation shall be made on the basis of a 
year of 365 or 366 days, as the case may be.

        5.2     FEES OF ADMINISTRATIVE AGENT AND ARRANGER.  Borrower shall 
pay to (a) Administrative Agent, Lenders, and Arranger, as the case may be, 
solely for their respective accounts, the fees described in that certain 
separate letter agreement dated as of December 3, 1998, between Borrower, 
Administrative Agent, and Arranger, and (b) each of the Agents, all the fees 
specified in the letter dated December 9, 

                                      43
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

1998, addressed to Borrower from the Agents, which payments shall be made on 
the dates specified, and in amounts calculated in accordance with, such 
letter agreements.

        5.3     REVOLVER FACILITY COMMITMENT FEES.  Following the Closing 
Date, Borrower shall pay to Administrative Agent, for the ratable account of 
Revolver Lenders, a commitment fee, payable in installments in arrears, on 
each March 31, June 30, September 30, and December 31 and on the Termination 
Date for the Revolver Facility, commencing December 31, 1998.  Each 
installment shall be, in an amount equal to the Applicable Margin for 
Commitment Fees MULTIPLIED BY the amount by which (a) the average daily 
Revolver Commitment exceeds (b) the average daily Revolver Commitment Usage, 
in each case during the period from and including the last payment date to 
and excluding the payment date for such installment; PROVIDED THAT, each such 
installment shall be calculated in accordance with SECTION 5.1(f).  Solely 
for the purposes of this SECTION 5.3, (i) determinations of the average daily 
Revolver Commitment Usage shall exclude the Revolver Principal Debt of all 
Swing Line Borrowings (provided that, solely for NationsBank in its capacity 
as the Lender under the Swing Line Subfacility [and any successor Lender 
thereunder, "SWING LINE LENDER"], Borrowings under the Swing Line Subfacility 
will be included in determining the Revolver Commitment Usage for such Swing 
Line Lender up to, but not in excess of, the amount which causes the Revolver 
Commitment Usage of such Swing Line Lender to equal the Committed Sum in 
respect of the Revolver Facility of such Lender); and (ii) "RATABLE" shall 
mean, for any period of calculation, with respect to any Revolver Lender, that 
proportion which (x) the average daily unused Revolver Committed Sum of such 
Revolver Lender during such period bears to (y) the amount of the average daily 
unused Revolver Commitment during such period.

SECTION 6.      SECURITY; GUARANTIES.

        6.1     COLLATERAL.  To secure full and complete payment and 
performance of the Obligation, the Companies hereby jointly and severally 
grant and convey to, and create in favor of Administrative Agent for the 
ratable benefit of the Lenders, first priority Liens in, to, and on all 
assets of the Companies as more particularly described in the Collateral 
Documents (the "COLLATERAL"); PROVIDED THAT, no Agent or any Lender hereby 
assumes or is made the transferee of any obligations of any Company regarding 
any of the Collateral.

        6.2     GUARANTIES.  As an inducement to Agents and Lenders to enter 
into this Agreement, Borrower shall cause Sygnet Communications and each 
other Subsidiary to execute and deliver to Administrative Agent a Guaranty 
substantially in the form and upon the terms of EXHIBIT C, providing for the 
guarantee of payment and performance of the Obligation.

        6.3     FUTURE LIENS.  Promptly after (a) the acquisition of any 
assets (real, personal, tangible, or intangible) by any Company, (b) the 
removal, termination, or expiration of any prohibitions upon the granting of 
a Lien in any asset (real, personal, tangible, or intangible) of any Company, 
or (c) upon the designation, formation, or acquisition of any new Subsidiary 
(the assets and stock of such new Subsidiary and the assets described in 
CLAUSES (a) and (b) hereof are referred to herein as the "ADDITIONAL 
ASSETS"), Borrower shall (or shall cause such other Company to) execute and 
deliver to Administrative Agent all further instruments and documents 
(including, without limitation, Collateral Documents and all certificates and 
instruments representing shares of stock or evidencing Debt and any realty 
appraisals as Administrative Agent may require with respect to any such 
Additional Assets), and shall take all further action that may be necessary 
or desirable, or that Administrative Agent may reasonably request, to grant, 
perfect, and protect Liens in favor of Administrative Agent for the benefit 
of the Lenders in such Additional Assets, as security for the Obligation; IT 
BEING EXPRESSLY UNDERSTOOD that the granting of such additional security 

                                      44
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

for the Obligation is a material inducement to the execution and delivery of 
this Agreement by each Lender.  Upon satisfying the terms and conditions 
hereof, such Additional Assets shall be included in the "COLLATERAL" for all 
purposes under the Loan Papers, and all references to the "COLLATERAL" in the 
Loan Papers shall include the Additional Assets.

        6.4     RELEASE OF COLLATERAL.  Upon any sale, transfer, or 
disposition of Collateral which is expressly permitted pursuant to the Loan 
Papers (or is otherwise authorized by Required Lenders or Lenders, as the 
case may be), and upon ten (10) Business Days' prior written request by 
Borrower (which request must be accompanied by true and correct copies of (a) 
all documents of transfer or disposition, including any contract of sale, (b) 
a preliminary closing statement and instructions to the title company, if 
any, and (c) all requested release instruments), Administrative Agent shall 
(and is hereby irrevocably authorized by the Lenders to) execute such 
documents as may be necessary to evidence the release of Liens granted to 
Administrative Agent for the benefit of Lenders pursuant hereto in such 
Collateral; PROVIDED THAT, (i) no such release of Lien shall be granted if 
any Default or Potential Default has occurred and is continuing, including, 
without limitation, the failure to make certain mandatory prepayments in 
accordance with SECTIONS 2.7(b)(ii) in conjunction with the sale or transfer 
of such Collateral; (ii) Administrative Agent shall not be required to 
execute any such document on terms which, in Administrative Agent's opinion, 
would expose Administrative Agent to liability or create any obligation or 
entail any consequence OTHER THAN the release of such Liens without recourse 
or warranty; and (iii) such release shall not in any manner discharge, 
affect, or impair the Obligation, or Liens upon (or obligations of any 
Company in respect of) all interests retained by the Companies, including 
(without limitation) the proceeds of any sale, all of which shall continue to 
constitute Collateral.

        6.5     NEGATIVE PLEDGE.  Notwithstanding the provisions of SECTION 
6.1 hereof, until such time as Administrative Agent or Required Lenders 
otherwise require, the Companies shall not be required to: (i) perfect Liens 
on certain assets constituting interests in assigned leases (other than the 
Sygnet Towers Lease), vehicles, fixtures, or real estate, SO LONG AS the 
aggregate value of such assets does not exceed $5,000,000, or (ii) to grant 
specific assignments of easements, licenses, permits, certificates of 
compliance, and certificates of approval issued by regulatory authorities, 
franchises, or like grants of authority or service agreements, To the extent 
Administrative Agent and Required Lenders agree to delay the perfection or 
attachment of any Lien granted pursuant to SECTION 6.1 hereof, for whatever 
reason, the Companies hereby covenant and agree not to directly create, 
incur, grant, suffer, or permit to be created or incurred any Lien on any 
such assets, OTHER THAN Permitted Liens.  Furthermore, within thirty (30) 
days of the request of Administrative Agent, Borrower shall (or shall cause 
each Company to) execute and deliver to Administrative Agent all instruments 
and documents (including, without limitation, certificates and instruments 
and documents representing shares of stock or evidencing Debt) and shall take 
all further action that may be necessary or desirable, or that Administrative 
Agent may reasonably request, to grant, perfect, and protect Liens in favor 
of Administrative Agent for the benefit of Lenders, in such assets, as 
security for the Obligation; IT BEING EXPRESSLY UNDERSTOOD that the 
provisions of this negative pledge are a material inducement to the execution 
and delivery of this Agreement by each Lender.

        6.6     CONTROL; LIMITATION OF RIGHTS.  Notwithstanding anything 
herein or in any other Loan Paper to the contrary, (a) the transactions 
contemplated hereby (i) do not and will not constitute, create, or have the 
effect of constituting or creating, directly or indirectly, actual or 
practical ownership of the Companies by Agents or Lenders, or control, 
affirmative or negative, direct or indirect, by Agents or Lenders over the 
management or any other aspect of the operation of the Companies, which 
ownership or control remains exclusively and at all times in the Companies, 
and (ii) do not and will not constitute the transfer, assignment, or 
disposition in any manner, voluntary or involuntary, directly or indirectly, 
of any 

                                      45
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

Authorization at any time issued by the FCC or any PUC to the Companies, or 
the transfer of control of the Companies within the meaning of SECTION 310(d) 
of the Communications Act; and (b) Administrative Agent shall not, without 
first obtaining the approval of the FCC or any applicable PUC, take any 
action pursuant to this Agreement or any other Loan Paper that would 
constitute or result in any assignment of any Authorization or any change of 
control of the Companies, if such assignment or change of control would 
require, under then existing Law (including the written rules and regulations 
promulgated by the FCC or any such PUC), the prior approval of the FCC or any 
such PUC.
        
SECTION 7       CONDITIONS PRECEDENT.

        7.1     CONDITIONS PRECEDENT TO CLOSING.  This Agreement shall not 
become effective, and Lenders shall not be obligated to advance any 
Borrowing, unless Administrative Agent has received all of the agreements, 
documents, instruments, and other items described on SCHEDULE 7.1.

        7.2     CONDITIONS PRECEDENT TO A PERMITTED ACQUISITION.  On or prior 
to the consummation of any Acquisition (whether or not the purchase price for 
such Acquisition is funded by Borrowings), Borrower shall have satisfied the 
conditions and delivered, or caused to be delivered, to Administrative Agent, 
all documents and certificates set forth on SCHEDULE 7.2 by no later than the 
dates specified for satisfaction of such conditions on SCHEDULE 7.2.  
Promptly upon receipt of each Permitted Acquisition Compliance Certificate 
and each Permitted Acquisition Loan Closing Certificate, Administrative Agent 
shall provide copies of such certificates to Lenders.  All documentation 
delivered and satisfaction of conditions pursuant to the requirements of 
SECTION 7.2 must be satisfactory to Administrative Agent.  To the extent any 
Borrowing is being requested in connection with the consummation of the 
Acquisition, the conditions set forth in SECTIONS 7.2 and 7.3 hereof must be 
satisfied prior to the making of any such Borrowing.

        7.3     CONDITIONS PRECEDENT TO EACH BORROWING.  In addition to the 
conditions stated in SECTIONS 7.1 and 7.2, Lenders will not be obligated to 
fund (as opposed to continue or convert) any Borrowing, unless on the date of 
such Borrowing (and after giving effect thereto):  (a) Administrative Agent 
shall have timely received therefor a Notice of Borrowing; (b) all of the 
representations and warranties of any Company set forth in the Loan Papers 
are true and correct in all material respects (except to the extent that (i) 
the representations and warranties speak to a specific date or (ii) the facts 
on which such representations and warranties are based have been changed by 
transactions contemplated or permitted by the Loan Papers); (c) no change in 
the financial condition or business of any Company which could be a Material 
Adverse Event shall have occurred; (d) no Default or Potential Default shall 
have occurred and be continuing; (e) the funding of such Borrowings is 
permitted by Law; (f) in the event all or any part of the proceeds of the 
Borrowing will be used to finance a Distribution to the extent permitted by 
SECTION 9.21, Administrative Agent shall have received all such 
certifications, financial information, and projections as Administrative 
Agent may reasonably request; and (g) all matters related to such Borrowing 
must be satisfactory to Required Lenders and their respective counsel in 
their reasonable determination, and upon the reasonable request of 
Administrative Agent, Borrower shall deliver to Administrative Agent evidence 
substantiating any of the matters in the Loan Papers which are necessary to 
enable Borrower to qualify for such Borrowing. Each Notice of Borrowing 
delivered to Administrative Agent shall constitute the representation and 
warranty by Borrower to Administrative Agent that the statements above are 
true and correct in all respects.  Each condition precedent in this Agreement 
is material to the transactions contemplated in this Agreement, and time is 
of the essence in respect of each thereof.  Subject to the prior approval of 
Required Lenders, Lenders may fund any Borrowing without all conditions being 
satisfied, but, to the extent permitted by Law, the same shall not be deemed 
to be a waiver of the requirement that each 

                                      46
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

such condition precedent be satisfied as a prerequisite for any subsequent 
funding or issuance, unless Required Lenders specifically waive each such 
item in writing.

SECTION 8       REPRESENTATIONS AND WARRANTIES.  Borrower and each other 
Company represent and warrant to Administrative Agent and Lenders as follows:

        8.1     PURPOSE OF CREDIT FACILITIES.  Borrower will use (or will 
loan such proceeds to its Companies to so use) all proceeds of Borrowings for 
one or more of the following:  (a) to finance all or a portion of the Sygnet 
Merger and the related costs and expenses; (b) to finance other Permitted 
Acquisitions; (c) to refinance certain indebtedness of Sygnet Wireless, Inc. 
existing as of the Closing Date, including the Sygnet Senior Notes; (d) to 
finance Capital Expenditures; (e) to finance certain investments permitted by 
the Loan Papers; (f) to finance certain permitted Distributions; (g) for 
working capital of Borrower and its Subsidiaries; and (h) for general 
corporate purposes.  No Company is engaged principally, or as one of its 
important activities, in the business of extending credit for the purpose of 
purchasing or carrying any "MARGIN STOCK" within the meaning of REGULATION U. 
No part of the proceeds of any Borrowing will be used, directly or 
indirectly, for a purpose which violates any Law, including, without 
limitation, the provisions of REGULATIONS T, U, or X (as enacted by the Board 
of Governors of the Federal Reserve System, as amended).

        8.2     EXISTENCE, GOOD STANDING, AUTHORITY, AND AUTHORIZATIONS.  
Each Company is duly organized, validly existing, and in good standing under 
the Laws of its jurisdiction of organization (such jurisdictions being 
identified on SCHEDULE 8.3, as supplemented and modified in writing from time 
to time to reflect any changes to such Schedule as a result of transactions 
permitted by the Loan Papers).  Each Company is duly qualified to transact 
business and is in good standing in each jurisdiction where the nature and 
extent of its business and properties require the same.  Each of the 
Companies possesses all Authorizations, franchises, permits, licenses, 
certificates of compliance, and approvals and grants of authority necessary, 
including, without limitation, any Authorization issued by the FCC, all of 
which are described on SCHEDULE 8.2 hereto, necessary or required in the 
conduct of its respective business(es), and the same are valid, binding, 
enforceable, and subsisting without any defaults thereunder or enforceable 
adverse limitations thereon and are not subject to any proceedings or claims 
opposing the issuance, development, or use thereof or contesting the validity 
thereof.  No authorization, consent, approval, waiver, license, or formal 
exemptions from, nor any filing, declaration, or registration with, any 
Governmental Authority (federal, state, or local), or non-governmental 
entity, under the terms of contracts or otherwise, is required by reason of 
or in connection with the execution and performance of the Loan Papers by the 
Companies or consummation of the Sygnet Merger, except as shall have been 
obtained on or prior to the Closing Date.

        8.3     SUBSIDIARIES; CAPITAL STOCK.  The Companies have no 
Subsidiaries except as disclosed on SCHEDULE 8.3 (as supplemented and 
modified in writing from time to time to reflect any changes to such Schedule 
as a result of transactions permitted by the Loan Papers).  All of the 
outstanding shares of capital stock (or similar voting interests) of each 
Subsidiary are duly authorized, validly issued, fully paid, and nonassessable 
and are owned of record and beneficially as set forth on SCHEDULE 8.3 (as 
supplemented and modified in writing from time to time to reflect any changes 
to such Schedule as a result of transactions permitted by the Loan Papers), 
free and clear of any Liens, restrictions, claims, or rights of another 
Person, other than Permitted Liens, and none of such shares owned by any 
Company is subject to any restriction on transfer thereof except for 
restrictions imposed by securities Laws and general corporate Laws.  No 
Company has outstanding any warrant, option, or other right of any Person to 
acquire any of its capital stock or similar equity interests.

                                      47
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

        8.4     AUTHORIZATION AND CONTRAVENTION.  The execution and delivery 
by each Company of each Loan Paper to which it is a party and the performance 
by such Company of its obligations thereunder (a) are within the corporate 
power of such Company, (b) will have been duly authorized by all necessary 
corporate or partnership action on the part of such Company when such Loan 
Paper is executed and delivered, (c) require no action by or in respect of, 
or filing with, any Governmental Authority, which action or filing has not 
been taken or made on or prior to the Closing Date (or if later, the date of 
execution and delivery of such Loan Paper), (d) will not violate any 
provision of the charter, bylaws, or partnership agreement of such Company, 
(e) will not violate any provision of Law applicable to it, other than such 
violations which individually or collectively could not be a Material Adverse 
Event, (f) will not violate any material written or oral agreements, 
contracts, commitments, or understandings to which it is a party, other than 
such violations which could not be a Material Adverse Event, or (g) will not 
result in the creation or imposition of any Lien on any asset of any Company. 
The Companies have (or will have upon consummation thereof) all necessary 
consents and approvals of any Person or Governmental Authority required to be 
obtained in order to effect the Sygnet Merger and any other any asset 
transfer, change of control, merger, or consolidation permitted by the Loan 
Papers.

        8.5     BINDING EFFECT.  Upon execution and delivery by all parties 
thereto, each Loan Paper will constitute a legal, valid, and binding 
obligation of each Company party thereto, enforceable against each such 
Company in accordance with its terms, except as enforceability may be limited 
by applicable Debtor Relief Laws and general principles of equity.

        8.6     FINANCIAL STATEMENTS.  The Current Financials were prepared 
in accordance with GAAP and present fairly, in all material respects, the 
consolidated financial condition, results of operations, and cash flows of 
the Companies as of and for the portion of the fiscal year ending on the date 
or dates thereof (subject only to normal year-end audit adjustments).  There 
were no material liabilities, direct or indirect, fixed or contingent, of the 
Companies as of the date or dates of the Current Financials which are 
required under GAAP to be reflected therein or in the notes thereto, and are 
not so reflected.  Except for transactions directly related to, or 
specifically contemplated by, the Loan Papers, there have been no changes in 
the consolidated financial condition of the Companies from that shown in the 
Current Financials after such date which could be a Material Adverse Event, 
nor has Borrower or any Company incurred any liability (including, without 
limitation, any liability under any Environmental Law), direct or indirect, 
fixed or contingent, after such date which could be a Material Adverse Event.

        8.7     LITIGATION, CLAIMS, INVESTIGATIONS.  No Company is subject 
to, or aware of the threat of, any Litigation which is reasonably likely to 
be determined adversely to any Company, and, if so adversely determined, 
could (individually or collectively with other Litigation) be a Material 
Adverse Event.  There are no outstanding orders or judgments for the payment 
of money in excess of $1,000,000 (individually or collectively) or any 
warrant of attachment, sequestration, or similar proceeding against the 
assets of any Company having a value (individually or collectively) of 
$1,000,000 or more which is not either (a) stayed on appeal or (b) being 
diligently contested in good faith by appropriate proceedings and adequate 
reserves have been set aside on the books of such Company in accordance with 
GAAP.  There are no formal complaints, suits, claims, investigations, or 
proceedings initiated at or by any Governmental Authority pending or 
threatened by or against any Company relating to the Sygnet Merger, the 
transactions evidenced by the Loan Papers, or which could be a Material 
Adverse Event, nor any judgments, decrees, or orders of any Governmental 
Authority outstanding against any Company that could be a Material Adverse 
Event.

        8.8     TAXES.  All Tax returns of each Company required to be filed 
have been filed (or extensions have been granted) prior to delinquency, 
except for any such returns for which the failure to 

                                      48
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

so file could not be a Material Adverse Event, and all Taxes imposed upon 
each Company which are due and payable have been paid prior to delinquency, 
OTHER THAN Taxes for which the criteria for Permitted Liens (as specified in 
SECTION 9.13(b)(vi)) have been satisfied or for which nonpayment thereof 
could not constitute a Material Adverse Event.

        8.9     ENVIRONMENTAL MATTERS. No Company (a) knows of any 
environmental condition or circumstance, such as the presence or Release of 
any Hazardous Substance, on any property presently or previously owned by any 
Company that could be a Material Adverse Event, (b) knows of any violation by 
any Company of any Environmental Law, except for such violations that could 
not be a Material Adverse Event, or (c) knows that any Company is under any 
obligation to remedy any violation of any Environmental Law, except for such 
obligations that could not be a Material Adverse Event; PROVIDED, HOWEVER, 
that each Company (x) to the best of its knowledge, has in full force and 
effect all environmental permits, licenses, and approvals required to conduct 
its operations and is operating in substantial compliance thereunder, and (y) 
has taken prudent steps to determine that its properties and operations are 
not in violation of any Environmental Law.

        8.10    EMPLOYEE BENEFIT PLANS.  (a) No Employee Plan has incurred an 
accumulated funding deficiency, as defined in SECTION 302 of ERISA and 
SECTION 412 of the Code, (b) neither Borrower nor any ERISA Affiliate has 
incurred material liability which is currently due and remains unpaid under 
TITLE IV of ERISA to the PBGC or to an Employee Plan in connection with any 
such Employee Plan, (c) neither Borrower nor any ERISA Affiliate has 
withdrawn in whole or in part from participation in a Multiemployer Plan, (d)

ordinary course of business, or (iii) property with title defects or failures 
in title which, when considered in the aggregate, would not be a Material 
Adverse Event, or (b) as otherwise permitted by the Loan Papers.  Except for 
Permitted Liens, there is no Lien on any property of any Company, and the 
execution, delivery, performance, or observance of the Loan Papers will not 
require or result in the creation of any Lien on such property.

        8.12    GOVERNMENT REGULATIONS.  No Company is subject to regulation 
under the INVESTMENT COMPANY ACT OF 1940, as amended, the PUBLIC UTILITY 
HOLDING COMPANY ACT OF 1935, as amended, or any other Law (other than

System and the requirements of any PUC or public service commission) which

Permitted Debt.

        8.15    MATERIAL AGREEMENTS; MANAGEMENT AGREEMENTS.  SCHEDULE 8.15

material default under any of such contracts.  There are no failures of any 
material written or oral agreements, contracts, commitments, or 
understandings to which any Company is a party to be in full force and effect 
which could be a Material Adverse Event, and no default or potential default 
exists on the part of any Company thereunder which could be a Material 
Adverse Event.  No Company is a party to any management or consulting 
agreement for the provision of services to it, except as described in 
SCHEDULE 8.15 hereto.

        8.16    INSURANCE.  Each Company maintains, with financially sound, 
responsible, and reputable insurance companies or associations, insurance 
concerning its properties and businesses against such casualties and 
contingencies and of such types and in such amounts (and with co-insurance 
and deductibles) as is customary in the case of same or similar businesses.

        8.17    LABOR MATTERS.  There are no actual or threatened strikes, 
labor disputes, slow downs, walkouts, or other concerted interruptions of 
operations by the employees of any Company that could be a Material Adverse 
Event.  Hours worked by and payment made to employees of the Companies have 
not been in violation of the FAIR LABOR STANDARDS ACT or any other applicable 
Law dealing with such matters, other than any such violations, individually 
or collectively, which could not constitute a Material Adverse Event.  All 
payments due from any Company on account of employee health and welfare 
insurance have been paid or accrued as a liability on its books, other than 
any such nonpayments which could not, individually or collectively, 
constitute a Material Adverse Event.

        8.18    SOLVENCY.  At the time of each Borrowing hereunder, and on 
the dates of the Sygnet Merger, the Sygnet Towers Sale, and each Permitted 
Acquisition, each Company is (and after giving effect to the transactions 
contemplated by the Loan Papers, the Sygnet Merger, any Permitted 
Acquisition, and any incurrence of additional Debt, will be) Solvent.

        8.19    INTELLECTUAL PROPERTY.  Each Company owns or has sufficient 
and legally enforceable rights to use all material licenses, patents, patent 
applications, copyrights, service marks, trademarks, trademark applications, 
and trade names necessary to continue to conduct its businesses as heretofore 
conducted by it, now conducted by it, and now proposed to be conducted by it. 
Each Company is conducting its business without infringement or claim of 
infringement of any license, patent, copyright, service mark, trademark, 
trade name, trade secret, or other intellectual property right of others, 
other than any such infringements or claims which, if successfully asserted 
against or determined adversely to any Company, could not, individually or 
collectively, constitute a Material Adverse Event. 

        8.20    COMPLIANCE WITH LAWS.  No Company is in violation of any Laws 
(including, without limitation, the Communications Act, Environmental Laws, 
and those Laws administered by the FCC and any PUC), other than such 
violations which could not, individually or collectively, be a Material 
Adverse Event.  No Company has received notice alleging any noncompliance 
with any Laws, except for such noncompliance which no longer exists, or which 
could not constitute a Material Adverse Event.

        9.6     PAYMENT OF OBLIGATIONS.  Borrower shall pay the Obligation in
accordance with the terms and provisions of the Loan Papers.  Each Company
(a) shall promptly pay (or renew and extend) all of its material obligations as
the same become due (unless such obligations [other than the Obligation] are
being contested in good faith by appropriate proceedings), and (b) shall not
make any voluntary prepayment of principal of, or interest on, any other Debt
(other than the Obligation), whether subordinate to the Obligation or not or
(ii) use proceeds from the Facilities to make any payment or prepayment of
principal of, or interest on, or sinking fund payment in respect of any other
Debt of any Company.

        9.7     MAINTENANCE OF EXISTENCE, ASSETS, AND BUSINESS.  Except as
otherwise permitted by SECTION 9.25, each Company shall at all times:
(a) maintain its existence and good standing in the jurisdiction of its
organization and its authority to transact business in all other jurisdictions
where the failure to so maintain its authority to transact business could be a
Material Adverse Event; (b) maintain all licenses, permits, and franchises
necessary for its business where the failure to so maintain could be a Material
Adverse Event; (c) keep all of its assets which are useful in and necessary to
its business in good working order and condition (ordinary wear and tear
excepted) and make all necessary repairs thereto and replacements thereof; and
(d) do all things necessary to obtain, renew, extend, and continue in effect all
Authorizations issued by the FCC or any applicable PUC which may at any time and
from time to time be necessary for the Companies to operate their businesses in
compliance with applicable Law, where the failure to so renew, extend, or
continue in effect could be a Material Adverse Event.

        9.8     INSURANCE.  The Companies shall, at their sole cost and expense,
keep and maintain the Collateral owned by such Company insured for its actual
cash value against loss or damage by fire, theft, explosion, flood, and all
other hazards and risks ordinarily insured against by other owners or users of
such properties in similar businesses of comparable size and notify
Administrative Agent promptly of any occurrence causing a material loss or
decline in value of the Collateral and the estimated (or actual, if available)
amount of such loss or decline.  All policies of insurance on the Collateral
shall be in a form, with such deductibles, and with insurers recognized as
adequate by prudent business Persons in the same businesses as the Companies and
acceptable to Administrative Agent, and all such policies shall be in such
amount as may be satisfactory to Administrative Agent.  On the Closing Date and
thereafter as each policy is renewed and extended, the Companies shall deliver
to Administrative Agent a certificate of insurance for each policy of insurance
and evidence of payment of all premiums therefor.  Such policies of insurance
and the certificates evidencing the same shall contain an endorsement, in form
and substance acceptable to Administrative Agent, showing loss payable to
Administrative Agent for the benefit of Lenders.  Such endorsement, or an
independent instrument furnished to Administrative Agent, shall provide that the
insurance companies will give Administrative Agent at least thirty (30) days
prior written notice before any such policy or policies of insurance shall be
altered or canceled and that no act or default of any Company or any other
Person shall affect the Right of Administrative Agent to recover under such
policy or policies of insurance in case of loss or damage.  Upon the payment by
the insurer of the proceeds of any such policy of insurance and if no Default
has occurred and is continuing, the Company so insured may retain such insurance
if such proceeds are used to repair or replace the property the damage or
destruction of which gave rise to the payment of such insurance proceeds;
PROVIDED, HOWEVER, that any insurance proceeds not used for repair or
replacement in accordance herewith, UNLESS paid as reimbursement of expenses
incurred and business losses suffered in connection with the loss or damage to
the Collateral, shall be paid to or retained by Administrative Agent for
application as a mandatory prepayment on the Obligation.

        9.9     PRESERVATION AND PROTECTION OF RIGHTS.  Each Company shall
perform such acts and duly authorize, execute, acknowledge, deliver, file, and
record any additional agreements, documents, instruments, and certificates as
Administrative Agent or Required Lenders may reasonably deem necessary 


                                      56

prohibited transaction, accumulated funding deficiency, termination 
proceeding, or withdrawal would result in liability on the part of any 
Company (individually or collectively) in excess of $1,000,000.

        9.11    ENVIRONMENTAL LAWS.  Each Company shall (a) conduct its business
so as to comply with all applicable Environmental Laws and shall promptly take
corrective action to remedy any non-compliance with any Environmental Law,
(b) promptly investigate and remediate any known Release or threatened Release
of any Hazardous Substance on any property owned by any Company or at any
facility operated by any Company to the extent and degree necessary to comply

        the commitment to extend credit hereunder shall automatically terminate
        and the entire unpaid balance of the Obligation shall automatically
        become due and payable without any action or notice of any kind
        whatsoever.

                (b)     If any Default exists, Administrative Agent shall, upon
        the request of Required Lenders (subject to the terms of SECTION 12) or
        Required Lenders may, do any one or more of the following:  (i) if the
        maturity of the Obligation has not already been accelerated under
        SECTION 11.1(a), declare the entire unpaid balance of the Obligation, or
        any part thereof, immediately due and payable, whereupon it shall be due
        and payable; (ii) terminate the commitments of Lenders to extend credit
        hereunder; (iii) reduce any claim to judgment; (iv) to the extent
        permitted by Law, exercise (or request each Lender to, and each Lender
        shall be entitled to, exercise) the Rights of offset or banker's Lien
        against the interest of each Company in and to every account and other
        property of each Company which are in the possession of Administrative
        Agent or any Lender to the extent of the full amount of the Obligation
        (to the extent permitted by Law, each Company being deemed directly
        obligated to each Lender in the full amount of the Obligation for such
        purposes); and (v) exercise any and all other legal or equitable Rights
        afforded by the Loan Papers, the Laws of the State of Texas, or any
        other applicable jurisdiction as Administrative Agent shall deem
        appropriate, or otherwise, including, but not limited to, the Right to
        bring suit or other proceedings before any Governmental Authority either
        for specific performance of any covenant or condition contained in any
        of the Loan Papers or in aid of the exercise of any Right granted to
        Administrative Agent or any Lender in any of the Loan Papers.

        11.2    COMPANY WAIVERS.  To the extent permitted by Law, the Companies
hereby waive presentment and demand for payment, protest, notice of intention to
accelerate, notice of acceleration, and notice of protest and nonpayment, and
agree that their respective liability with respect to the Obligation (or any
part thereof) shall not be affected by any renewal or extension in the time of
payment of the 


                                      67
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

Obligation (or any part thereof), by any indulgence, or by any release or 
change in any security for the payment of the Obligation (or any part 
thereof).

        11.3    PERFORMANCE BY ADMINISTRATIVE AGENT.  If any covenant, duty, or
agreement of any Company is not performed in accordance with the terms of the
Loan Papers, after the occurrence and during the continuance of a Default,
Administrative Agent may, at its option (but subject to the approval of Required
Lenders), perform or attempt to perform such covenant, duty, or agreement on
behalf of such Company.  In such event, any amount expended by Administrative
Agent in such performance or attempted performance shall be payable by the
Companies, jointly and severally, to Administrative Agent on demand, shall
become part of the Obligation, and shall bear interest at the Default Rate from
the date of such expenditure by Administrative Agent until paid. 
Notwithstanding the foregoing, it is expressly understood that Administrative
Agent does not assume, and shall never have, except by its express written
consent, any liability or responsibility for the performance of any covenant,
duty, or agreement of any Company.

        11.4    DELEGATION OF DUTIES AND RIGHTS.  Lenders may perform any of
their duties or exercise any of their Rights under the Loan Papers by or through
their respective Representatives.

        11.5    NOT IN CONTROL.  Nothing in any Loan Paper shall, or shall be
deemed to (a) give any Agent or any Lender the Right to exercise control over
the assets (including real property), affairs, or management of any Company, (b)
preclude or interfere with compliance by any Company with any Law, or (c)
require any act or omission by any Company that may be harmful to Persons or
property.  Any "MATERIAL ADVERSE EVENT" or other materiality qualifier in any
representation, warranty, covenant, or other provision of any Loan Paper is
included for credit documentation purposes only and shall not, and shall not be
deemed to, mean that any Agent or any Lender acquiesces in any non-compliance by
any Company with any Law or document, or that any Agent or any Lender does not
expect the Companies to promptly, diligently, and continuously carry out all
appropriate removal, remediation, and termination activities required or
appropriate in accordance with all Environmental Laws.  The Agents and the
Lenders have no fiduciary relationship with or fiduciary duty to Borrower or any
Company arising out of or in connection with the Loan Papers, and the
relationship between the Agents and the Lenders, on the one hand, and Borrower
and the Companies, on the other hand, in connection with the Loan Papers is
solely that of debtor and creditor. The power of the Agents and Lenders under
the Loan Papers is limited to the Rights provided in the Loan Papers, which
Rights exist solely to assure payment and performance of the Obligation and may
be exercised in a manner calculated by the Agents and Lenders in their
respective good faith business judgment.

        11.6    COURSE OF DEALING.  The acceptance by Administrative Agent or
Lenders at any time and from time to time of partial payment on the Obligation
shall not be deemed to be a waiver of any Default then existing.  No waiver by
Administrative Agent, Required Lenders, or Lenders of any Default shall be
deemed to be a waiver of any other then-existing or subsequent Default.  No
delay or omission by Administrative Agent, Required Lenders, or Lenders in
exercising any Right under the Loan Papers shall impair such Right or be
construed as a waiver thereof or any acquiescence therein, nor shall any single
or partial exercise of any such Right preclude other or further exercise
thereof, or the exercise of any other Right under the Loan Papers or otherwise.

        11.7    CUMULATIVE RIGHTS.  All Rights available to Administrative Agent
and Lenders under the Loan Papers are cumulative of and in addition to all other
Rights granted to Administrative Agent and Lenders at law or in equity, whether
or not the Obligation is due and payable and whether or not

                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

Administrative Agent or Lenders have instituted any suit for collection, 
foreclosure, or other action in connection with the Loan Papers.

        11.8    APPLICATION OF PROCEEDS.  Any and all proceeds ever received by
Administrative Agent or Lenders from the exercise of any Rights pertaining to
the Obligation shall be applied to the Obligation in the order and manner set
forth in SECTION 3.11.

        11.9    CERTAIN PROCEEDINGS.  Each Company will promptly execute and
deliver, or cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers
Administrative Agent or Lenders may reasonably request in connection with the
obtaining of any consent, approval, registration, qualification, permit,
license, or Authorization of any Governmental Authority or other Person
necessary or appropriate for the effective exercise of any Rights under the Loan
Papers.  Because the Companies agree that Administrative Agent's and Lenders'
remedies at Law for failure of the Companies to comply with the provisions of
this Section would be inadequate and that such failure would not be adequately
compensable in damages, the Companies agree that the covenants of this Section
may be specifically enforced.

        11.10   LIMITATION OF RIGHTS.  Notwithstanding any other provision of
this Agreement or any other Loan Paper, any action taken or proposed to be taken
by Administrative Agent, any Agent, or any Lender under any Loan Paper which
would affect the operational, voting, or other control of any Company, shall be
pursuant to SECTION 310(d) of the COMMUNICATIONS ACT OF 1934 (as amended), any
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.

        11.11   EXPENDITURES BY LENDERS.  Borrower shall promptly pay within
fifteen (15) Business Days after request therefor (a) all reasonable costs,
fees, and expenses paid or incurred by Administrative Agent and Arranger,
incident to any Loan Paper (including, but not limited to, the reasonable fees
and expenses of counsel to Administrative Agent and Arranger and the allocated
cost of internal counsel in connection with the negotiation, preparation,
delivery, execution, coordination and administration of the Loan Papers and any
related amendment, waiver, or consent) and (b) all reasonable costs and expenses
of Lenders and Administrative Agent incurred by Administrative Agent or any
Lender in connection with the enforcement of the obligations of any Company
arising under the Loan Papers (including, without limitation, costs and expenses
incurred in connection with any workout or bankruptcy) or the exercise of any
Rights arising under the Loan Papers (including, but not limited to, reasonable
attorneys' fees including allocated cost of internal counsel, court costs and
other costs of collection), all of which shall be a part of the Obligation and
shall bear interest at the Default Rate from the date due until the date repaid.

        11.12   INDEMNIFICATION.  BORROWER AND EACH COMPANY AGREE TO INDEMNIFY
AND HOLD HARMLESS EACH AGENT, ARRANGER, AND EACH LENDER AND EACH OF THEIR
RESPECTIVE AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES,
AGENTS, ATTORNEYS, AND ADVISORS (EACH, AN "INDEMNIFIED PARTY") FROM AND AGAINST
ANY AND ALL CLAIMS, DAMAGES, LOSSES, LIABILITIES, COSTS, AND EXPENSES
(INCLUDING, WITHOUT LIMITATION, REASONABLE ATTORNEYS' FEES) THAT MAY BE INCURRED
BY OR ASSERTED OR AWARDED AGAINST ANY INDEMNIFIED PARTY, IN EACH CASE ARISING
OUT OF OR IN CONNECTION WITH OR BY REASON OF (INCLUDING, WITHOUT LIMITATION, IN
CONNECTION WITH ANY INVESTIGATION, LITIGATION, OR PROCEEDING OR PREPARATION OF
DEFENSE IN CONNECTION THEREWITH) THE LOAN PAPERS, ANY OF THE TRANSACTIONS
CONTEMPLATED HEREIN OR THE ACTUAL OR PROPOSED USE OF THE PROCEEDS OF THE
BORROWINGS (INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF THE
INDEMNIFIED PARTY), EXCEPT TO THE EXTENT SUCH CLAIM, DAMAGE,

<PAGE>

LOSS, LIABILITY, COST, OR EXPENSE IS FOUND IN A FINAL, NON-APPEALABLE 
JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM SUCH 
INDEMNIFIED PARTY'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.  IN THE CASE OF 
AN INVESTIGATION, LITIGATION OR OTHER PROCEEDING TO WHICH THE INDEMNITY IN 
THIS SECTION 11.12 APPLIES, SUCH INDEMNITY SHALL BE EFFECTIVE WHETHER OR NOT 
SUCH INVESTIGATION, LITIGATION OR PROCEEDING IS BROUGHT BY THE BORROWER, ITS 
DIRECTORS, SHAREHOLDERS OR CREDITORS OR AN INDEMNIFIED PARTY OR ANY OTHER 
PERSON OR ANY INDEMNIFIED PARTY IS OTHERWISE A PARTY THERETO AND WHETHER OR 
NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED.  BORROWER AND EACH 
COMPANY AGREE NOT TO ASSERT ANY CLAIM AGAINST ANY INDEMNIFIED PARTY ON ANY 
THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL, OR PUNITIVE 
DAMAGES ARISING OUT OF OR OTHERWISE RELATING TO THE LOAN PAPERS, ANY OF THE 
TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR PROPOSED USE OF THE 
PROCEEDS OF THE BORROWINGS.  WITHOUT PREJUDICE TO THE SURVIVAL OF ANY OTHER 
AGREEMENT OF THE BORROWER HEREUNDER, THE AGREEMENTS AND OBLIGATIONS OF THE 
BORROWER CONTAINED IN THIS SECTION 11.12 SHALL SURVIVE THE PAYMENT IN FULL OF 
THE BORROWINGS AND ALL OTHER AMOUNTS PAYABLE UNDER THIS AGREEMENT.

SECTION 12      AGREEMENT AMONG LENDERS.

        12.1    ADMINISTRATIVE AGENT.

                (a)     Each Lender hereby appoints NationsBank, N.A. (and
        NationsBank, N.A. hereby accepts such appointment) as its nominee and
        agent, in its name and on its behalf:  (i) to act as nominee for and on
        behalf of such Lender in and under all Loan Papers; (ii) to arrange the
        means whereby the funds of Lenders are to be made available to Borrower
        under the Loan Papers; (iii) to take such action as may be requested by
        any Lender under the Loan Papers (when such Lender is entitled to make
        such request under the Loan Papers and after such requesting Lender has
        obtained the concurrence of such other Lenders as may be required under
        the Loan Papers); (iv) to receive all documents and items to be
        furnished to Lenders under the Loan Papers; (v) to timely distribute,
        and Administrative Agent agrees to so distribute, to each Lender all
        material information, requests, documents, and items received from
        Borrower under the Loan Papers; (vi) to promptly distribute to each
        Lender its ratable part of each payment or prepayment (whether
        voluntary, as proceeds of collateral upon or after foreclosure, as
        proceeds of insurance thereon, or otherwise) in accordance with the
        terms of the Loan Papers; (vii) to deliver to the appropriate Persons
        requests, demands, approvals, and consents received from Lenders; and
        (viii) to execute, on behalf of Lenders, such releases or other
        documents or instruments as are permitted by the Loan Papers or as
        directed by Lenders from time to time; PROVIDED, HOWEVER, Administrative
        Agent shall not be required to take any action which exposes
        Administrative Agent to personal liability or which is contrary to the
        Loan Papers or applicable Law.

                (b)     Administrative Agent may resign at any time as
        Administrative Agent under the Loan Papers by giving written notice
        thereof to Lenders and may be removed as Administrative Agent under the
        Loan Papers at any time with cause by Required Lenders.  Should the
        initial or any successor Administrative Agent ever cease to be a party
        hereto or should the initial or any successor Administrative Agent ever
        resign or be removed as Administrative Agent, then Required Lenders
        shall elect the successor Administrative Agent from among the Lenders
        (other than the resigning Administrative Agent).  If no successor
        Administrative Agent shall have been so appointed by Required Lenders,
        within 30 days after the retiring Administrative Agent's giving of
        notice of resignation or Required Lenders' removal of the retiring
        Administrative Agent, then 


                                      70
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

        the retiring Administrative Agent may, on behalf of Lenders, appoint 
        a successor Administrative Agent, which shall be a commercial bank 
        having a combined capital and surplus of at least $1,000,000,000.  
        Upon the acceptance of any appointment as Administrative Agent under 
        the Loan Papers by a successor Administrative Agent, such successor 
        Administrative Agent shall thereupon succeed to and become vested 
        with all the Rights of the retiring Administrative Agent, and the 
        retiring Administrative Agent shall be discharged from its duties and 
        obligations of Administrative Agent under the Loan Papers, and each 
        Lender shall execute such documents as any Lender may reasonably 
        request to reflect such change in and under the Loan Papers. After 
        any retiring Administrative Agent's resignation or removal as 
        Administrative Agent under the Loan Papers, the provisions of this 
        SECTION 12 shall inure to its benefit as to any actions taken or 
        omitted to be taken by it while it was Administrative Agent under the 
        Loan Papers.

                (c)     Administrative Agent, in its capacity as a Lender, shall
        have the same Rights under the Loan Papers as any other Lender and may
        exercise the same as though it were not acting as Administrative Agent;
        the term "LENDER" shall, unless the context otherwise indicates, include
        Administrative Agent; and any resignation, or removal of by
        Administrative Agent hereunder shall not impair or otherwise affect any
        Rights which it has or may have in its capacity as an individual Lender.
        Each Lender and Borrower agree that Administrative Agent is not a
        fiduciary for Lenders or for Borrower but simply is acting in the
        capacity described herein to alleviate administrative burdens for both
        Borrower and Lenders, that Administrative Agent has no duties or
        responsibilities to Lenders or Borrower except those expressly set forth
        herein, and that Administrative Agent in its capacity as a Lender has
        all Rights of any other Lender.

                (d)     Administrative Agent and its Affiliates may now or
        hereafter be engaged in one or more loan, letter of credit, leasing, or
        other financing transactions with Borrower, act as trustee or depositary
        for Borrower, or otherwise be engaged in other transactions with
        Borrower (collectively, the "OTHER ACTIVITIES") not the subject of the
        Loan Papers.  Without limiting the Rights of Lenders specifically set
        forth in the Loan Papers, Administrative Agent and its Affiliates shall
        not be responsible to account to Lenders for such other activities, and
        no Lender shall have any interest in any other activities, any present
        or future guaranties by or for the account of Borrower which are not
        contemplated or included in the Loan Papers, any present or future
        offset exercised by Administrative Agent and its Affiliates in respect
        of such other activities, any present or future property taken as
        security for any such other activities, or any property now or hereafter
        in the possession or control of Administrative Agent or its Affiliates
        which may be or become security for the obligations of Borrower arising
        under the Loan Papers by reason of the general description of
        indebtedness secured or of property contained in any other agreements,
        documents or instruments related to any such other activities; PROVIDED
        THAT, if any payments in respect of such guaranties or such property or
        the proceeds thereof shall be applied to reduction of the obligations of
        Borrower arising under the Loan Papers, then each Lender shall be
        entitled to share in such application ratably.

        12.2    EXPENSES.  Upon demand by Administrative Agent, each Lender
shall pay its Pro Rata Part of any reasonable expenses (including, without
limitation, court costs, reasonable attorneys' fees, and other costs of
collection) incurred by Administrative Agent in connection with any of the Loan
Papers if and to the extent Administrative Agent does not receive reimbursement
therefor from other sources within 60 days after incurred; PROVIDED THAT, each
Lender shall be entitled to receive its Pro Rata Part of any reimbursement for
such expenses, or part thereof, which Administrative Agent subsequently receives
from such other sources.

                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

        12.3    PROPORTIONATE ABSORPTION OF LOSSES.  Except as otherwise
provided in the Loan Papers, nothing in the Loan Papers shall be deemed to give
any Lender any advantage over any other Lender insofar as the Obligation arising
under the Loan Papers is concerned, or to relieve any Lender from absorbing its
Pro Rata Part of any losses sustained with respect to the Obligation (except to
the extent such losses result from unilateral actions or inactions of any Lender
that are not made in accordance with the terms and provisions of the Loan
Papers).

        12.4    DELEGATION OF DUTIES; RELIANCE.  Administrative Agent may
perform any of its duties or exercise any of its Rights under the Loan Papers by
or through its Representatives.  Administrative Agent and its Representatives
shall (a) be entitled to rely upon (and shall be protected in relying upon) any
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telecopy, telegram, telex or teletype message, statement, order, or other
documents or conversation believed by it or them to be genuine and correct and
to have been signed or made by the proper Person and, with respect to legal
matters, upon opinion of counsel selected by Administrative Agent, (b) be
entitled to deem and treat each Lender as the owner and holder of the Principal
Debt owed to such Lender for all purposes until, subject to SECTION 13.13,
written notice of the assignment or transfer thereof shall have been given to
and received by Administrative Agent (and any request, authorization, consent,
or approval of any Lender shall be conclusive and binding on each subsequent
holder, assignee, or transferee of the Principal Debt owed to such Lender or
portion thereof until such notice is given and received), (c) not be deemed to
have notice of the occurrence of a Default unless a responsible officer of
Administrative Agent, who handles matters associated with the Loan Papers and
transactions thereunder, has received written notice from a Lender or Borrower
and stating that such notice is a "NOTICE OF DEFAULT," and (d) be entitled to
consult with legal counsel (including counsel for Borrower), independent
accountants, and other experts selected by Administrative Agent and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts.

        12.5    LIMITATION OF LIABILITY.

                (a)     None of the Agents or any of their respective
        Representatives shall be liable for any action taken or omitted to be
        taken by it or them under the Loan Papers in good faith and reasonably
        believed by it or them to be within the discretion or power conferred
        upon it or them by the Loan Papers or be responsible for the
        consequences of any error of judgment, except for fraud, gross
        negligence, or willful misconduct; and none of the Agents or any of
        their respective Representatives has a fiduciary relationship with any
        Lender by virtue of the Loan Papers (PROVIDED THAT, nothing herein shall
        negate the obligation of Administrative Agent or Administrative Agent to
        account for funds received by it for the account of any Lender).

                (b)     Unless indemnified to its satisfaction against loss,
        cost, liability, and expense, neither Administrative Agent nor any other
        Agent shall be compelled to do any act under the Loan Papers or to take
        any action toward the execution or enforcement of the powers thereby
        created or to prosecute or defend any suit in respect of the Loan
        Papers.  If Administrative Agent requests instructions from Lenders or
        Required Lenders, as the case may be, with respect to any act or action
        (including, but not limited to, any failure to act) in connection with
        any Loan Paper, Administrative Agent shall be entitled (but shall not be
        required) to refrain (without incurring any liability to any Person by
        so refraining) from such act or action unless and until it has received
        such instructions.  Except where action of Required Lenders or all
        Lenders is required in the Loan Papers, Administrative Agent may act
        hereunder in its own discretion without requesting instructions. In no
        event, however, shall Administrative Agent or any of its respective


                                      72
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

        Representatives be required to take any action which it or they
        determine could incur for it or them criminal or onerous civil
        liability.  Without limiting the generality of the foregoing, no Lender
        shall have any right of action against Administrative Agent as a result
        of Administrative Agent's acting or refraining from acting hereunder in
        accordance with the instructions of Required Lenders (or all Lenders if
        required in the Loan Papers).

                (c)     Administrative Agent nor any other Agent shall be
        responsible in any manner to any Lender or any Participant for, and each
        Lender represents and warrants that it has not relied upon
        Administrative Agent or any other Agent in respect of, (i) the
        creditworthiness of any Company and the risks involved to such Lender,
        (ii) the effectiveness, enforceability, genuineness, validity, or the
        due execution of any Loan Paper, (iii) any representation, warranty,
        document, certificate, report, or statement made therein or furnished
        thereunder or in connection therewith, (iv) the existence, priority, or
        perfection of any Lien hereafter granted or purported to be granted
        under any Loan Paper, or (v) observation of or compliance with any of
        the terms, covenants, or conditions of any Loan Paper on the part of any
        Company.  Each Lender agrees to indemnify Administrative Agent and its
        respective Representatives and hold them harmless from and against (but
        limited to such Lender's Pro Rata Part of) any and all liabilities,
        obligations, losses, damages, penalties, actions, judgments, suits,
        costs, reasonable expenses, and reasonable disbursements of any kind or
        nature whatsoever which may be imposed on, asserted against, or incurred
        by them in any way relating to or arising out of the Loan Papers or any
        action taken or omitted by them under the Loan Papers (INCLUDING ANY OF
        THE FOREGOING ARISING FROM THE NEGLIGENCE OF ADMINISTRATIVE AGENT OR ITS
        REPRESENTATIVES), to the extent Administrative Agent and its respective
        Representatives are not reimbursed for such amounts by any Company
        (PROVIDED THAT, Administrative Agent, and its respective Representatives
        shall not have the right to be indemnified hereunder for its or their
        own fraud, gross negligence, or willful misconduct).

        12.6    DEFAULT; COLLATERAL.  Upon the occurrence and continuance of a
Default, Lenders agree to promptly confer in order that Required Lenders or
Lenders, as the case may be, may agree upon a course of action for the
enforcement of the Rights of Lenders; and Administrative Agent shall be entitled
to refrain from taking any action (without incurring any liability to any Person
for so refraining) unless and until Administrative Agent shall have received
instructions from Required Lenders.  All rights of action under this Agreement
and under the Notes and all rights to the Collateral, if any, hereunder may be
enforced by Administrative Agent and any suit or proceeding instituted by
Administrative Agent in furtherance of such enforcement shall be brought in its
name as Administrative Agent without the necessity of joining as plaintiffs or
defendants any other Lender, and the recovery of any judgment shall be for the
benefit of Lenders subject to the expenses of Administrative Agent.  In actions
with respect to any property of Borrower, Administrative Agent is acting for the
ratable benefit of each Lender.  Any and all agreements to subordinate (whether
made heretofore or hereafter) other indebtedness or obligations of Borrower to
the Obligation shall be construed as being for the ratable benefit of each
Lender.

        12.7    LIMITATION OF LIABILITY.  To the extent permitted by Law,
(a) neither Administrative Agent nor any other Agent (acting in their respective
agent capacities) shall incur any liability to any other Lender, Agent, or
Participant except for acts or omissions resulting from its own fraud, gross
negligence or wilful misconduct, and (b) neither Administrative Agent nor any
other Agent, Lender, or Participant shall incur any liability to any other
Person for any act or omission of any other Lender, Agent, or Participant.


                                      73

<PAGE>

        12.8    RELATIONSHIP OF LENDERS.  Nothing herein shall be construed as
creating a partnership or joint venture among Agents and Lenders.

        12.9    BENEFITS OF AGREEMENT.  Except for the representations and
covenants in SECTION 12.1(c) in favor of Borrower, none of the provisions of
this SECTION 12 shall inure to the benefit of any Company or any other Person
other than Lenders; consequently, no Company or any other Person shall be
entitled to rely upon, or to raise as a defense, in any manner whatsoever, the
failure of any Agent or any Lender to comply with such provisions.

        12.10   AGENTS.  None of the Lenders identified in this Agreement as 
"CO-SYNDICATION AGENTS" or "CO-DOCUMENTATION AGENTS" shall have any rights,
powers, obligations, liabilities, responsibilities, or duties under this
Agreement other than those applicable to all Lenders as such.  Without limiting
the foregoing, none of the Lenders so identified as a "CO-SYNDICATION AGENTS" or
"CO-DOCUMENTATION AGENTS" shall have or be deemed to have any fiduciary
relationship with any Lender.

        12.11   OBLIGATIONS SEVERAL.  The obligations of Lenders hereunder are
several, and each Lender hereunder shall not be responsible for the obligations
of the other Lenders hereunder, nor will the failure of one Lender to perform
any of its obligations hereunder relieve the other Lenders from the performance
of their respective obligations hereunder.

SECTION 13      MISCELLANEOUS.

        13.1    HEADINGS.  The headings, captions, and arrangements used in any
of the Loan Papers are, unless specified otherwise, for convenience only and
shall not be deemed to limit, amplify, or modify the terms of the Loan Papers,
nor affect the meaning thereof.

        13.2    NONBUSINESS DAYS.  In any case where any payment or action is
due under any Loan Paper on a day which is not a Business Day, such payment or
action may be delayed until the next-succeeding Business Day, but interest and
fees shall continue to accrue in respect of any payment to which it is
applicable until such payment is in fact made; PROVIDED THAT, if, in the case of
any such payment in respect of a Eurodollar Rate Borrowing, the next-succeeding
Business Day is in the next calendar month, then such payment shall be made on
the next-preceding Business Day.

        13.3    NOTICES.  Unless specifically otherwise provided, whenever any
Loan Paper requires or permits any consent, approval, notice, request, or demand
from one party to another, such communication must be in writing (which may be
by telex or telecopy) to be effective and shall be deemed to have been given
(a) if by telex, when transmitted to the telex number, if any, for such party,
and the appropriate answer back is received, (b) if by telecopy, when
transmitted to the telecopy number for such party (and all such communications
sent by telecopy shall be confirmed promptly thereafter by personal delivery or
mailing in accordance with the provisions of this section; PROVIDED, THAT any
requirement in this parenthetical shall not affect the date on which such
telecopy shall be deemed to have been delivered), (c) if by mail, on the third
Business Day after it is enclosed in an envelope, properly addressed to such
party, properly stamped, sealed, and deposited in the appropriate official
postal service, or (d) if by any other means, when actually delivered to such
party.  Until changed by notice pursuant hereto, the address (and telex and
telecopy numbers, if any) for Administrative Agent and each Lender,
Administrative Agent, and other Agents is set forth on SCHEDULE 2.1, and for
Borrower and each Company is the address set forth by Borrower's signature on
the signature page of this Agreement and for each Guarantor is the address set
forth by such Guarantor's signature on the signature page of its Guaranty.  A
copy of each communication

to Administrative Agent shall also be sent to Haynes and Boone, LLP, 901 Main 
Street, Dallas, Texas 75202, Fax: 214/651-5940, Attn: Karen S. Nelson.

        13.4    FORM AND NUMBER OF DOCUMENTS.  Each agreement, document,
instrument, or other writing to be furnished under any provision of this
Agreement must be in form and substance and in such number of counterparts as
may be reasonably satisfactory to Administrative Agent and its counsel.

        13.5    EXCEPTIONS TO COVENANTS.  No Company shall take any action or
fail to take any action which is permitted as an exception to any of the
covenants contained in any Loan Paper if such action or omission would result in
the breach of any other covenant contained in any of the Loan Papers.

        13.6    SURVIVAL.  All covenants, agreements, undertakings,
representations, and warranties made in any of the Loan Papers shall survive all
closings under the Loan Papers and, except as otherwise indicated, shall not be
affected by any investigation made by any party.  All rights of, and provisions
relating to, reimbursement and indemnification of Administrative Agent, any
Agent, or any Lender shall survive termination of this Agreement and payment in
full of the Obligation.

        13.7    GOVERNING LAW.  THE LAWS OF THE STATE OF TEXAS AND OF THE UNITED
STATES OF AMERICA SHALL GOVERN THE RIGHTS AND DUTIES OF THE PARTIES TO THE LOAN
PAPERS AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION OF THE
LOAN PAPERS.

        13.8    INVALID PROVISIONS.  If any provision in any Loan Paper is held
to be illegal, invalid, or unenforceable, such provision shall be fully
severable; the appropriate Loan Paper shall be construed and enforced as if such
provision had never comprised a part thereof; and the remaining provisions
thereof shall remain in full force and effect and shall not be affected by such
provision or by its severance therefrom.  Administrative Agent, Lenders, and
each Company party to such Loan Paper agree to negotiate, in good faith, the
terms of a replacement provision as similar to the severed provision as may be
possible and be legal, valid, and enforceable.

        13.9    ENTIRETY.  THE RIGHTS AND OBLIGATIONS OF THE COMPANIES,
GUARANTORS, LENDERS, AND AGENTS SHALL BE DETERMINED SOLELY FROM WRITTEN
AGREEMENTS, DOCUMENTS, AND INSTRUMENTS, AND ANY PRIOR ORAL AGREEMENTS BETWEEN
SUCH PARTIES ARE SUPERSEDED BY AND MERGED INTO SUCH WRITINGS.  THIS AGREEMENT
(AS AMENDED IN WRITING FROM TIME TO TIME) AND THE OTHER WRITTEN LOAN PAPERS
EXECUTED BY ANY COMPANY, ANY GUARANTOR, ANY LENDER, AND/OR ANY AGENT, (TOGETHER
WITH ALL COMMITMENT LETTERS AND FEE LETTERS ONLY AS THEY RELATE TO THE PAYMENT
OF FEES AFTER THE CLOSING DATE) REPRESENT THE FINAL AGREEMENT BETWEEN THE
COMPANIES, THE GUARANTORS, LENDERS, AND AGENTS, AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY SUCH
PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN SUCH PARTIES.

        13.10   JURISDICTION; VENUE; SERVICE OF PROCESS; JURY TRIAL.  EACH PARTY
HERETO, IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS, HEREBY
(A) IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE STATE AND
FEDERAL COURTS LOCATED IN TEXAS, AND AGREES AND CONSENTS THAT SERVICE OF PROCESS
MAY BE MADE UPON IT IN ANY LEGAL PROCEEDING ARISING OUT OF OR IN CONNECTION WITH
THE LOAN PAPERS AND THE OBLIGATION BY SERVICE OF PROCESS AS PROVIDED BY TEXAS
LAW, (B) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY
OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY
LITIGATION ARISING OUT OF OR IN CONNECTION WITH THE LOAN PAPERS AND THE
OBLIGATION BROUGHT IN ANY SUCH COURT, (C) IRREVOCABLY WAIVES ANY CLAIMS THAT ANY
LITIGATION BROUGHT IN ANY SUCH COURT HAS BEEN

<PAGE>

BROUGHT IN AN INCONVENIENT FORUM, (D) AGREES TO DESIGNATE AND MAINTAIN AN 
AGENT FOR SERVICE OF PROCESS IN TEXAS IN CONNECTION WITH ANY SUCH LITIGATION 
AND TO DELIVER TO ADMINISTRATIVE AGENT EVIDENCE THEREOF, IF REQUESTED, (E) 
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE 
AFOREMENTIONED COURTS IN ANY SUCH LITIGATION BY THE MAILING OF COPIES THEREOF 
BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, AT ITS ADDRESS 
SET FORTH HEREIN, (F) IRREVOCABLY AGREES THAT ANY LEGAL PROCEEDING AGAINST 
ANY PARTY HERETO ARISING OUT OF OR IN CONNECTION WITH THE LOAN PAPERS OR THE 
OBLIGATION SHALL BE BROUGHT IN ONE OF THE AFOREMENTIONED COURTS, AND (G) 
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ITS RESPECTIVE 
RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING 
OUT OF ANY LOAN PAPER OR THE TRANSACTIONS CONTEMPLATED THEREBY.  The scope of 
each of the foregoing waivers is intended to be all-encompassing of any and 
all disputes that may be filed in any court and that relate to the subject 
matter of this transaction, including, without limitation, contract claims, 
tort claims, breach of duty claims, and all other common law and statutory 
claims. The Companies, Guarantors, and each other party to this Agreement 
acknowledge that this waiver is a material inducement to the agreement of 
each party hereto to enter into a business relationship, that each has 
already relied on this waiver in entering into this Agreement, and each will 
continue to rely on each of such waivers in related future dealings.  The 
Companies, Guarantors, and each other party to this Agreement warrant and 
represent that they have reviewed these waivers with their legal counsel, and 
that they knowingly and voluntarily agree to each such waiver following 
consultation with legal counsel.  THE WAIVERS IN THIS SECTION 13.10 ARE 
IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER ORALLY OR IN 
WRITING, AND THESE WAIVERS SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, 
SUPPLEMENTS, AND REPLACEMENTS TO OR OF THIS OR ANY OTHER LOAN PAPER.  In the 
event of Litigation, this Agreement may be filed as a written consent to a 
trial by the court.

        13.11   AMENDMENTS, CONSENTS, CONFLICTS, AND WAIVERS.

                (a)     Except as otherwise specifically provided, (i) this
        Agreement may only be amended, modified or waived by an instrument in
        writing executed jointly by Borrower and Required Lenders, and, in the
        case of any matter affecting Administrative Agent (EXCEPT removal of
        Administrative Agent as provided in SECTION 12) by Administrative Agent,
        and may only be supplemented by documents delivered or to be delivered
        in accordance with the express terms hereof, and (ii) the other Loan
        Papers may only be the subject of an amendment, modification, or waiver
        if Borrower and Required Lenders, and, in the case of any matter
        affecting Administrative Agent (EXCEPT as set forth above),
        Administrative Agent, have approved same.

                (b)     Any amendment to or consent or waiver under this
        Agreement or any Loan Paper which purports to accomplish any of the
        following must be by an instrument in writing executed by Borrower and
        executed (or approved, as the case may be) by each Lender affected
        thereby, and, in the case of any matter affecting Administrative Agent,
        by Administrative Agent: (i) extends the due date or reduces the amount
        of any scheduled payment of the Obligation or any scheduled reduction of
        the Revolver Commitment beyond the date specified in the Loan Papers;
        (ii) reduces the interest rate or decreases the amount of interest,
        fees, or other sums payable to Administrative Agent or Lenders hereunder
        (except such reductions as are contemplated by this Agreement); (iii)
        change the percentage of the Total Commitment or Revolver Commitment, or
        of the Principal Debt which shall be required for the Lenders or any of
        them to take any action under this SECTION 13.11 or any other provision
        of this Agreement or any Loan Paper; or (iv) except as otherwise
        permitted by any Loan Paper, waives compliance with, amends, or releases
        (in whole or in part) any material 


                                      76
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

        Guaranty or releases (in whole or in part) any material Collateral for 
        the Obligation; or (v) changes this CLAUSE (b) or any other matter 
        specifically requiring the consent of all Lenders hereunder.  Without 
        the consent of such Lender, no Lender's "COMMITTED SUM" may be 
        increased.

                (c)     Any conflict or ambiguity between the terms and
        provisions herein and terms and provisions in any other Loan Paper shall
        be controlled by the terms and provisions herein.

                (d)     No course of dealing nor any failure or delay by
        Administrative Agent, any Lender, or any of their respective
        Representatives with respect to exercising any Right of Administrative
        Agent or any Lender hereunder shall operate as a waiver thereof.  A
        waiver must be in writing and signed by Administrative Agent and
        Required Lenders (or by all Lenders, if required hereunder) to be
        effective, and such waiver will be effective only in the specific
        instance and for the specific purpose for which it is given.

        13.12   MULTIPLE COUNTERPARTS.  This Agreement may be 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 Agreement, it shall not be necessary to produce or account
for more than one such counterpart.  It is not necessary that each Lender
execute the same counterpart so long as identical counterparts are executed by
Borrower, each Lender, and Administrative Agent.  This Agreement shall become
effective when counterparts hereof shall have been executed and delivered to
Administrative Agent by each Lender, Administrative Agent, and Borrower, or,
when Administrative Agent shall have received telecopied, telexed, or other
evidence satisfactory to it that such party has executed and is delivering to
Administrative Agent a counterpart hereof.

        13.13   SUCCESSORS AND ASSIGNS; ASSIGNMENTS AND PARTICIPATIONS.

                (a)     This Agreement shall be binding upon, and inure to the
        benefit of the parties hereto and their respective successors and
        assigns, EXCEPT THAT (i) Borrower may not, directly or indirectly,
        assign or transfer, or attempt to assign or transfer, any of its Rights,
        duties or obligations under any Loan Papers without the express written
        consent of all Lenders, and (ii) EXCEPT as permitted under this Section,
        no Lender may transfer, pledge, assign, sell any participation in, or
        otherwise encumber its portion of the Obligation.  

                (b)     Each Lender may assign to one or more Eligible Assignees
        all or a portion of its Rights and obligations under this Agreement and
        the other Loan Papers (including, without limitation, all or a portion
        of its Borrowings and its Notes); PROVIDED, HOWEVER, that:

                        (i)     each such assignment shall be to an Eligible
                Assignee;

                        (ii)    except in the case of an assignment to another
                Lender or an assignment of all of a Lender's Rights and
                obligations under this Agreement and the other Loan Papers, any
                such partial assignment shall be in an amount at least equal to
                $5,000,000 in the aggregate for all Facilities being assigned;
                PROVIDED THAT, no partial assignment for any Facility may be
                less than $1,000,000.

                        (iii)   each such assignment by a Lender shall be of a
                constant, and not varying, percentage of all of its Rights and
                obligations under this Agreement and the Notes; 


                                      77
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

                        (iv)    the parties to such assignment shall execute and
                deliver to the Administrative Agent for its acceptance an
                Assignment and Acceptance Agreement in the form of EXHIBIT F
                hereto, together with any Notes subject to such assignment and a
                processing fee of $3,500, PROVIDED HOWEVER, that with respect to
                an assignment to an Affiliate of Lender, the processing fee
                shall be $1,500.

        Upon execution, delivery, and acceptance of such Assignment and
        Acceptance Agreement, the assignee thereunder shall be a party hereto
        and, to the extent of such assignment, have the obligations, Rights, and
        benefits of a Lender under the Loan Papers and the assigning Lender
        shall, to the extent of such assignment, relinquish its rights and be
        released from its obligations under the Loan Papers.  Upon the
        consummation of any assignment pursuant to this Section, but only upon
        the request of the assignor or assignee made through Administrative
        Agent, Borrower shall issue appropriate Notes to the assignor and the
        assignee, reflecting such Assignment and Acceptance.  If the assignee is
        not incorporated under the laws of the United States of America or a
        state thereof, it shall deliver to Borrower and Administrative Agent
        certification as to exemption from deduction or withholding of Taxes in
        accordance with SECTION 4.6.

                (c)     Administrative Agent shall maintain at its address
        referred to in SECTION 13.3 a copy of each Assignment and Acceptance
        Agreement delivered to and accepted by it and a register for the
        recordation of the names and addresses of the Lenders and the
        Commitment, and principal amount of the Borrowings owing to, each Lender
        from time to time (the "REGISTER").  The entries in the Register shall
        be conclusive and binding for all purposes, absent manifest error, and
        Borrower, Administrative Agent and the Lenders may treat each Person
        whose name is recorded in the Register as a Lender hereunder for all
        purposes of the Loan Papers.  The Register shall be available for
        inspection by Borrower or any Lender at any reasonable time and from
        time to time upon reasonable prior notice.  Upon the consummation of any
        assignment in accordance with this SECTION 13.13, SCHEDULE 2.1 shall
        automatically be deemed amended (to the extent required) by
        Administrative Agent to reflect the name, address, and respective
        Committed Sums under the Facilities of the assignor and assignee.

                (d)     Upon its receipt of an Assignment and Acceptance
        Agreement executed by the parties thereto, together with any Notes
        subject to such assignment and payment of the processing fee, the
        Administrative Agent shall, if such Assignment and Acceptance has been
        completed and is in substantially the form of EXHIBIT F hereto, (i)
        accept such Assignment and Acceptance Agreement, (ii) record the
        information contained therein in the Register and (iii) give prompt
        notice thereof to the parties thereto.

                (e)     Subject to the provisions of this Section and in
        accordance with applicable Law, any Lender may, in the ordinary course
        of its business and in accordance with applicable Law, at any time sell
        to one or more Persons (each a "PARTICIPANT") participating interests in
        its portion of the Obligation.  In the event of any such sale to a
        Participant, (i) such Lender shall remain a "LENDER" under this
        Agreement and the Participant shall not constitute a "LENDER" hereunder,
        (ii) such Lender's obligations under this Agreement shall remain
        unchanged, (iii) such Lender shall remain solely responsible for the
        performance thereof, (iv) such Lender shall remain the holder of its
        share of the Principal Debt for all purposes under this Agreement,
        (v) Borrower and Administrative Agent shall continue to deal solely and
        directly with such Lender in connection with such Lender's Rights and
        obligations under the Loan Papers, and (vi) such Lender shall be solely
        responsible for any withholding taxes or any filing or reporting
        requirements relating to such participation and shall hold Borrower and
        Administrative Agent and their respective successors, 


                                      78
                                       DOBSON/SYGNET OPERATING CREDIT AGREEMENT
<PAGE>

        permitted assigns, officers, directors, employees, agents, and 
        representatives harmless against the same.  Participants shall have 
        no Rights under the Loan Papers, other than certain voting Rights as 
        provided below.  Subject to the following, each Lender shall be 
        entitled to obtain (on behalf of its Participants) the benefits of 
        SECTION 4 with respect to all participations in its part of the 
        Obligation outstanding from time to time SO LONG AS Borrower shall 
        not be obligated to pay any amount in excess of the amount that would 
        be due to such Lender under SECTION 4 calculated as though no 
        participations have been made.  No Lender shall sell any 
        participating interest under which the Participant shall have any 
        Rights to approve any amendment, modification, or waiver of any Loan 
        Paper, except to the extent such amendment, modification, or waiver 
        extends the due date for payment of any amount in respect of 
        principal (OTHER THAN mandatory prepayments), interest, or fees due 
        under the Loan Papers, reduces the interest rate or the amount of 
        principal or fees applicable to the Obligation (EXCEPT such 
        reductions as are contemplated by this Agreement), or releases any 
        material Guaranty or all or any substantial portion of the Collateral 
        for the Obligation under the Loan Papers (EXCEPT such releases as are 
        contemplated by this Agreement); PROVIDED THAT, in those cases where 
        a Participant is entitled to the benefits of SECTION 4 or a Lender 
        grants Rights to its Participants to approve amendments to or waivers 
        of the Loan Papers respecting the matters previously described in 
        this sentence, such Lender must include a voting mechanism in the 
        relevant participation agreement or agreements, as the case may be, 
        whereby a majority of such Lender's portion of the Obligation  
        (whether held by such Lender or Participant) shall control the vote 
        for all of such Lender's portion of the Obligation.  Except in the 
        case of the sale of a participating interest to another Lender, the 
        relevant participation agreement shall not permit the Participant to 
        transfer, pledge, assign, sell participations in, or otherwise 
        encumber its portion of the Obligation, unless the consent of the 
        transferring Lender (which consent will not be unreasonably withheld) 
        has been obtained.

                (f)     Notwithstanding any other provision set forth in this
        Agreement, any Lender may at any time assign and pledge all or any
        portion of its Borrowings and its Notes to any Federal Reserve Bank as
        collateral security pursuant to Regulation A and any Operating Circular
        issued by such Federal Reserve Bank without notice to, or the consent of
        Borrower or Administrative Agent and, with the consent of Borrower and
        Administrative Agent, after the Closing Date any Term Loan B Lender or
        any Term Loan C Lender which is a fund may pledge all or any portion of
        its Borrowings and its Notes to its trustee in support of its
        obligations to its trustee.  No such assignment shall release the
        assigning Lender from its obligations hereunder.

                (g)     Any Lender may furnish any information concerning the
        Companies in the possession of such Lender from time to time to Eligible
        Assignees and Participants (including prospective Eligible Assignees and
        Participants).

        13.14   DISCHARGE ONLY UPON PAYMENT IN FULL; REINSTATEMENT IN CERTAIN
CIRCUMSTANCES.  The obligations of each Company under the Loan Papers shall
remain in full force and effect until termination of the Total Commitment and
payment in full of the Principal Debt and of all interest, fees, and other
amounts of the Obligation then due and owing, EXCEPT that SECTIONS 4, 11, and
13, and any other provisions under the Loan Papers expressly intended to survive
by the terms hereof or by the terms of the applicable Loan Papers, shall survive
such termination.  If at any time any payment of the principal of or interest on
any Note or any other amount payable by any Company under any Loan Paper is
rescinded or must be otherwise restored or returned upon the insolvency,
bankruptcy, or reorganization of such Company or otherwise, the obligations of
each Company under the Loan Papers with respect to such payment shall be
reinstated as though such payment had been due but not made at such time.

                                FORM OF REVOLVER NOTE

$_____________                                             ____________ __, ____


        FOR VALUE RECEIVED, the undersigned, DOBSON/SYGNET OPERATING COMPANY
(including its successor by merger, Sygnet Wireless, Inc.) ("BORROWER"), hereby
promises to pay to the order of ______________________ ("LENDER"), at the
offices of NATIONSBANK, N.A., as Administrative Agent for Lender and others as
hereinafter described, on the Termination Date, the LESSER of
(a) $_______________ and (b) the aggregate Revolver Principal Debt disbursed by
Lender to Borrower and outstanding and unpaid on the Termination Date (TOGETHER
WITH accrued and unpaid interest thereon).

        This note has been executed and delivered under, and is subject to the

                                FORM OF GUARANTY

        THIS GUARANTY is executed as of December     , 1998, by 
___________________, a _________ corporation [partnership] ("GUARANTOR"), for 
the benefit of NATIONSBANK, N.A., a national banking association (in its 
capacity as Administrative Agent for Lenders).

        WHEREAS, Dobson/Sygnet Operating Company, (including its successor by 
merger, Sygnet Wireless, Inc.) ("BORROWER"), NationsBank, N.A., as 
Administrative Agent (including its permitted successors and assigns in such 
capacity, "ADMINISTRATIVE AGENT"), Lehman Commercial Paper Inc. and PNC Bank, 
National Association, as Co-Syndication Agents (including their permitted 
successors and assigns in such capacity, "SYNDICATION AGENT"), Toronto 
Dominion (Texas), Inc. and First Union National Bank, as Co-Documentation 
Agents (including their permitted successors and assigns in such capacity, 
"DOCUMENTATION AGENT"), and Lenders now or hereafter party to the Credit 
Agreement (including their respective permitted successors and assigns, 
"LENDERS") have entered into a Credit Agreement, dated as of December 23, 
1998 (as amended, modified, supplemented, or restated from time to time, the 
"CREDIT AGREEMENT");

        WHEREAS, provisions of the Credit Agreement permit Guarantor to 
directly or indirectly receive proceeds of Borrowings made pursuant thereto; 
and

        WHEREAS, this Guaranty is integral to the transactions contemplated 
by the Loan Papers and is a condition precedent to Lenders' obligations to 
extend credit under the Loan Papers.

        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:

        15.     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.

        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 Sections 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).

        GUARANTOR is defined in the preamble to this Guaranty.

                                                                     EXHIBIT C
<PAGE>

        LENDER means, individually, or LENDERS means, collectively, on any 
date of determination, Administrative Agent, Syndication Agent, Documentation 
Agent, and the 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.

        16.     GUARANTY.  This is an absolute, irrevocable, and continuing 
guaranty, 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 Papers have 
terminated, and all Financial Hedges with 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.

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

        18.     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.

        19.     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 any Guarantor previous to that demand of either the 
acceptance by Administrative Agent or Lenders of this Guaranty or the 
creation or incurrence of any Guaranteed Debt, pay the amount of the 
Guaranteed Debt then due and payable to Administrative Agent and Lenders.  It 
is not necessary for Administrative Agent or Lenders, in order to enforce 
that payment by any 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.

        20.     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.

                                       2                             EXHIBIT C
<PAGE>

        21.     SUBROGATION AND CONTRIBUTION.  Until payment in full of the 
Guaranteed Debt, the termination of the Obligation of Lenders to extend 
credit under the Loan Papers, and expiration of all Financial Hedges, (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.

        22.     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 Paper; (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 Paper; (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 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).

        23.     WAIVERS.  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, whether arising under Section 34.02 of the TEXAS BUSINESS AND 
COMMERCE CODE, as amended (regarding its Right to require Administrative 
Agent or Lenders to sue Borrower on accrued right of action following its 
written notice to Administrative Agent or Lenders), Section 17.001 of the 
TEXAS CIVIL PRACTICE AND REMEDIES CODE, as amended (allowing suit against it 
without suit against Borrower, but precluding entry of judgment against it 
before entry of judgment against Borrower), RULE 31 of the TEXAS RULES OF 
CIVIL PROCEDURE, as amended (requiring Administrative Agent or Lenders to 
join Borrower in any suit against it unless judgment has been previously 
entered against Borrower), or otherwise.

                                       3                             EXHIBIT C
<PAGE>

        24.     LOAN PAPERS.  By execution hereof, Guarantor covenants and 
agrees that certain representations, warranties, terms, covenants, and 
conditions set forth in the Loan Papers 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 Papers in favor 
of Administrative Agent and Lenders.  In the event the Credit Agreement 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 incorporated herein by reference shall nevertheless continue in 
full force and effect as obligations of Guarantor under this Guaranty.

        25.     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 Papers 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 Papers to which it is 
a party or any collateral securing any Guaranteed Debt.

        26.     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.

        27.     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.

        28.     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 
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 Papers 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.

                                       4                             EXHIBIT C
<PAGE>

        29.     LOAN PAPER.  This Guaranty is a Loan Paper 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.

        30.     NOTICES.  For purposes of SECTIONS 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.

        31.     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.

        32.     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 it.  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 it.

        33.     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 vests 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.

        15.     CERTAIN DEFINITIONS.  Unless otherwise defined herein, or the
context hereof 

                                                                     EXHIBIT D

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 conflicts 
with the definition given to such term in the UCC, the Credit Agreement 
definition shall control to the extent legally allowable; and (c) 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, Syndication Agent,
        Documentation 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; 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 Papers
        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 as enacted in the State of
        Texas or other applicable jurisdiction, as amended at the time in
        question.

        16.     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 

                                      2                              EXHIBIT D
<PAGE>

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 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 Section 9.318 or other applicable Law, but is otherwise limited by 
that prohibition.

        17.     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 property, equipment, fixtures, other goods, minerals, money,
        and deposit accounts, wherever located, now owned or hereafter acquired
        by such Debtor, and any and all present and future Tax refunds of any
        kind whatsoever to which any Debtor is now or shall hereafter become
        entitled.

                (b)     All present and future issued and outstanding shares of
        capital stock or other equity or investment securities now owned or

        listed on ANNEX B hereto, TOGETHER WITH all distributions thereon, all
        cash and noncash proceeds thereof, and any securities issued in
        substitution or replacement thereof (collectively, the "PLEDGED
        SHARES").

                (c)     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, the inter-
        company notes or notes from Cellular Partnership as listed on ANNEX B
        (collectively, the "COLLATERAL NOTES"), all Rights titles, interests,
        and Liens Debtor may have, be or become entitled to under all present
        and future security agreements, pledge agreements, deeds of trust,
        mortgages, guarantees, or other documents assuring or securing payment
        of the Collateral Notes (the "COLLATERAL NOTE SECURITY") in, to, and
        under all other loan and collateral documents relating to such
        instruments.

                (d)     All present and future Rights, titles, interests, and
        Liens (but none of the obligations) now owned or hereafter acquired by
        such Debtor in any partnership or joint venture, including, without
        limitation, any Cellular Partnership and the partnerships listed on
        ANNEX B hereof (collectively, the "PARTNERSHIP INTERESTS").

                (e)     All present and future Rights, titles, interests, and
        Liens (but none of the obligations) now owned or hereafter acquired by
        such Debtor, as lessee or landlord, in and to each lease covering 

                                      3                              EXHIBIT D
<PAGE>

        "ASSIGNED LEASE").

                (f)     Substantially all of the real estate now owned or
        hereafter acquired by such Debtor, TOGETHER WITH all improvements
        thereon and fixtures attached thereto.

        any other claim of such Debtor against any depository, now or hereafter

        limitation, certificates of deposit, other deposit instruments, and the
        [ESCROW DEPOSIT UNDER THE SYGNET PURCHASE AGREEMENT] (collectively, the
        "DEPOSIT ACCOUNTS").

                (h)     All present and future automobiles, trucks, truck
        tractors, trailers, semi-trailers, or other motor vehicles or rolling
        stock, now owned or hereafter acquired by such Debtor  (collectively,

                (i)     All present and future Rights, awards, and judgments to

        limitation, the Right to sue for past, present, or future

                (k)     All present and future Rights (including, without

        infringements), titles, and interests of such Debtor in and to all
        patents, patent applications, utility models, industrial models,
        designs, and any other forms of industrial intellectual property,
        including all grants, applications, reissues, continuations, and
        divisions with respect thereto and any Rights to use, manufacture, or
        sell any patent, including, without limitation, the patents listed on
        ANNEX B hereto (collectively, the "PATENTS").

                (l)     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 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.

                (m)     All proceeds of any sale or other disposition of any

        or not any such license or permit may lawfully be included as Collateral

                (n)     All present and future increases, profits, combinations,
        reclassifications, improvements, and products of, accessions,

        connection with, and substitutes and replacements for, all or part of
        the Collateral heretofore described.

                                      4                              EXHIBIT D
<PAGE>

                (o)     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.

                (p)     All present and future security for the payment to any
        Company 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.

[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. Section 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 INCLUDE ALL SECURITY AGREEMENTS OTHER THAN THE
SECURITY AGREEMENT FOR BORROWER.]

        18.     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 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, 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).

                                      5                              EXHIBIT D
<PAGE>

                (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 issued by the Subsidiaries to Debtor constitute 100% of
        the issued and outstanding common stock or other equity interests of
        such Subsidiaries.  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 Pledged
        Securities pursuant to this Security Agreement or for the execution,
        delivery, or performance 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

                                      6                              EXHIBIT D
<PAGE>

        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 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 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 such Deposit Accounts are 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 the Deposit Accounts; 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.

        19.     COVENANTS.  So long as Lenders are committed to extend credit 
to 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 SECTIONS 11.12 OF THE CREDIT
        AGREEMENT); AND (ii) CONSENT TO AND APPROVE THE VENUE, SERVICE OF
        PROCESS, AND WAIVER OF JURY TRIAL PROVISIONS OF SECTIONS 13.10 OF THE
        CREDIT AGREEMENT.

                (b)     RECORD OF COLLATERAL.  Maintain, at the place where
        Debtor is entitled to receive notices under the Loan Papers, 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 

                                      7                              EXHIBIT D
<PAGE>

        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, 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 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 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
        (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.

                                      8                              EXHIBIT D
<PAGE>

                (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
        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)     ESTOPPEL AND OTHER AGREEMENTS AND MATTERS.  Either
        (unless waived by Secured Party in its sole judgment without requiring
        approval of any other Lender) (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.

                (i)     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.

                (j)     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 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.

                (k)     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.

                (l)     SECURITIES.  Not sell, exchange, or otherwise dispose
        of, or grant any option, warrant, or other Right with respect to, any of
        the Pledged Shares; cause each Subsidiary not to issue any stock or
        other securities in addition to or in substitution for the Pledged
        Shares issued by the Subsidiaries, 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 the
        Subsidiaries or any other issuer of Securities 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
        Pledged Shares, including, without limitation, the filing of any claims
        with any court, liquidator, trustee, custodian, receiver, or other like
        person or party.

                (m)     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 

                                      9                              EXHIBIT D
<PAGE>

        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; and not consent to the amendment, modification, 
        surrender, impairment, forfeiture, cancellation, dissolution, or 
        termination of any Partnership, or material agreement relating 
        thereto; (v) not transfer, sell, or assign any of the Partnership 
        Interests or any part thereof; (vi) cause each Partnership to refrain 
        from granting any partnership interests in addition to or in 
        substitution for the Partnership Interests granted by the Partnerships,
        EXCEPT to Debtor; (vii) pledge hereunder, immediately upon Debtor's
        acquisition (directly or indirectly) thereof, any and all additional
        Partnership Interests of any Partnership granted to Debtor; and
        (viii) 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.

                (n)     DEPOSITORY BANK.  With respect to 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 with ITEM (iv) hereof; (ii) within thirty (30) days of the
        Closing 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 efforts to obtain the execution of such letter
        by each depository bank; (iii) deliver to Secured Party all certificates
        or instruments, if any, now or hereafter representing or evidencing the
        Deposit Accounts, accompanied by duly executed instruments of transfer
        or assignment in blank, all in form and substance satisfactory to
        Secured Party; and (iv) notify Secured Party prior to establishing any
        additional Deposit Accounts and, at the request of Secured Party, obtain
        from such depository bank an executed letter substantially in the form
        of ANNEX E and deliver the same to Secured Party.

        20.     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 Papers, 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.

                                      10                              EXHIBIT D

<PAGE>

                        (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 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 

                                      11                              EXHIBIT D

                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 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.

        21.     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 Papers, 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 this 

                                      12                              EXHIBIT D
<PAGE>

        Security Agreement, or otherwise fails to perform any of its obligations
        under the Loan Papers 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 
        Papers.  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, 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 pledgee; and, as to any Pledged
        Securities so registered, Debtor shall execute and deliver (or cause to
        be executed and delivered) to Secured Party all such proxies, powers of
        attorney, dividend coupons or orders, and other documents as Secured
        Party may reasonably request for the purpose of enabling Secured Party
        to exercise the voting Rights and powers which it is entitled to

                                      13                              EXHIBIT D
<PAGE>

        exercise under this Security 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 Security
        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 Collateral that is Pledged Securities.  If a
        Default or Potential Default exists and if Secured Party elects to
        exercise such Right, the Right to vote any Collateral that is 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 stock dividends or distributions in
        property made on or in respect of any Pledged Securities, and any
        proceeds of any Pledged Securities, whether such dividends,
        distributions, or proceeds result from a subdivision, combination, or
        reclassification of the outstanding capital stock of any issuer thereof
        or as a result of any merger, consolidation, acquisition, or other
        exchange of assets to which any issuer may be a party, or otherwise,
        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
        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 

                                      14                              EXHIBIT D
<PAGE>

        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 continuation
                statement with respect to the Security Interests created hereby,
                and to do any and all acts 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 

                                      15                              EXHIBIT D
<PAGE>

        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.
        
        22.     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 Papers, 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 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 

                                      16                              EXHIBIT D

        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 Papers.  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.

        23.     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 under the Credit Agreement, the payment
        in full of the Obligation, and the expiration of all Financial Hedges;
        (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 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 

                                      17                              EXHIBIT D
<PAGE>

        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, and the expiration of all Financial 
        Hedges, 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 PAPERS" referred to in the Credit
        Agreement, and all provisions relating to Loan Papers set forth in
        SECTIONS 13 of the Credit Agreement, other than the provisions set forth
        in SECTIONS 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 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 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 Papers 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 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 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.

                                      18                              EXHIBIT D
<PAGE>

                (e)     WAIVERS.  EXCEPT to the extent expressly otherwise
        provided herein or in other Loan Papers 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 agreement or a carbon, photographic, or other
        reproduction of this agreement, as a financing statement, but the
        failure of Secured Party to do so shall not impair the validity or
        enforceability of this agreement.

                (g)     AMENDMENTS.  This instrument 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.  THIS AGREEMENT SHALL BE GOVERNED AS TO
        ITS VALIDITY, INTERPRETATION, AND EFFECT IN ACCORDANCE WITH THE LAWS OF
        THE STATE OF TEXAS, EXCEPT AS REQUIRED BY MANDATORY PROVISIONS OF LAW
        AND EXCEPT IF THE VALIDITY OR PERFECTION OF THE SECURITY INTERESTS
        HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR
        COLLATERAL, ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE

                                      19                              EXHIBIT D

                "DEPOSIT BANK"), INCLUDING WITHOUT 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 Papers 
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.

        After such a demand is made, Administrative Agent shall have sole 
control 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 by the Deposit Bank in writing at the address and to the 
attention of the person set forth below (or at such other address or to the 
attention of such other person as the Deposit Bank may specify by written 
notice received by Administrative Agent and the Company) and when the Deposit 
Bank has had a reasonable time, based on the same standards as those 
applicable to payment and stop payment instructions generally, to act thereon.

                                      27                              EXHIBIT D

        4.      Upon request of Administrative Agent, Deposit Bank will send 
to Administrative Agent, at its above address, a copy of each periodic 
statement for the Account, as and when the statement is sent to the Company.

        5.      This letter agreement is binding upon the Deposit Bank and 
the Company and their successors and assigns and is enforceable by 
Administrative Agent and its successors and assigns.  It supersedes all prior 
agreements relating to the Deposit Bank, and it may not be modified or 
terminated EXCEPT upon Administrative Agent's written consent.  The Deposit 
Bank and the Company waive notice of acceptance hereof and of any action 
taken or omitted in reliance hereon.

                     FORM OF ASSIGNMENT AND ACCEPTANCE AGREEMENT

     Reference is made to the Credit Agreement dated as of December 23, 1998 (as
amended, modified, supplemented, or restated from time to time, the "CREDIT
AGREEMENT") among Dobson/Sygnet Operating Company, (including its successor by

Administrative Agent for Lenders ("ADMINISTRATIVE AGENT"), Lehman Commercial
Paper Inc. and PNC Bank, National Association, as Co-Syndication Agents, Toronto
Dominion (Texas), Inc. and First Union National Bank, as Co-Documentation
Agents, and Lenders party thereto.  Capitalized terms used herein and not
otherwise defined herein shall have the meanings assigned to such terms in the
Credit Agreement.

     "ASSIGNOR" and "ASSIGNEE" referred to on SCHEDULE 1 agree as follows:

     1.   Assignor hereby sells and assigns to Assignee, without recourse and
without representation or warranty EXCEPT as expressly set forth herein, and
Assignee hereby purchases and assumes from Assignor, an interest in and to
Assignor's Rights and obligations under the Credit Agreement and the related
Loan Papers as of the date hereof equal to the percentage interest specified on
SCHEDULE 1.  After giving effect to such sale and assignment, Assignor's and
Assignee's Committed Sums and the amount of the Borrowings under the Credit
Agreement owing to each of them will be as set forth on SCHEDULE 1.

     2.   Assignor (a) represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim; (b) makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties, or representations made in or in connection with the Loan Papers or
the execution, legality, validity, enforceability, genuineness, sufficiency, or
value of the Loan Papers or any other instrument or document furnished pursuant
thereto; (c) makes no representation or warranty and assumes no responsibility
with respect to the financial condition of any party to any Loan Paper or the
performance or observance by any such party of any of its obligations under the
Loan Papers or any other instrument or document furnished pursuant thereto; and
(d) attaches the Notes held by Assignor and requests that Administrative Agent
exchange such Notes for new Notes.  Such new Notes shall be prepared in
accordance with the provisions of SECTION 3.1(a) or SECTION 3.1(b) of the Credit
Agreement, as applicable, and will reflect the respective Committed Sums (for
each Facility, as appropriate) of Assignee and Assignor after giving effect to
this Assignment and Acceptance Agreement.

     3.   Assignee (a) confirms that it has received a copy of the Credit
Agreement, TOGETHER WITH copies of the current Financial Statements and such
other documents and information as it has deemed appropriate to make its own
credit analysis and decision to enter into this Assignment and Acceptance
Agreement; (b) 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;
(c) confirms that it is an Eligible Assignee; (d) 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; (e) agrees that it
will perform in accordance with their terms all of the obligations that by the
terms of the Credit Agreement are required to be performed by it as a Lender;
and (f) 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 


                                                                      Exhibit F

acceptance and recording by Administrative Agent.  The effective date for 
this Assignment and Acceptance Agreement (the "EFFECTIVE DATE") shall be the 
date of acceptance hereof by Administrative Agent, unless otherwise specified 
on SCHEDULE 1.

     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, 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 Papers for periods prior to the
Effective Date directly between themselves.

     7.   Unless Assignee is a Lender or an Affiliate of a Lender or unless a
Default or Potential Default then exists, this Assignment and Acceptance
Agreement is conditioned upon the consent of Borrower and Administrative Agent
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)(v) 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
TEXAS 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.

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 the Companies and such certificates of public
officials and of officers of 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 Guaranty executed
by Sygnet Communications, Inc., (d) the Pledge, Assignment, and Security
Agreement executed by Borrower in favor of Lender, (e) the Pledge, Assignment,
and Security Agreement executed by Sygnet Communications, Inc. in favor of
Lender (collectively with (d) above, the "SECURITY AGREEMENTS"), (f) Financing
Statements showing Borrower, as Debtor, and Administrative Agent, as Secured
Party, to be filed in appropriate jurisdictions; (g) Financing Statements
(collectively with (e) above, the "FINANCING STATEMENTS") showing Sygnet
Communications, Inc., as Debtor, and Administrative Agent, as Secured Party, to
be filed in appropriate jurisdictions; and (h) other Collateral Documents (all
of the foregoing are collectively, the "TRANSACTION DOCUMENTS"); additionally,
we have examined [describe documents evidencing the Dobson Acquisition] (the
"DOBSON ACQUISITION DOCUMENTS") .


                                                                    EXHIBIT G-1
<PAGE>


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

     1.   Each Company, DOC, and D/S Company (a) is a corporation validly
existing and in good standing under the Laws of its state of incorporation, (b)
is duly qualified to transact business as a foreign corporation in each
jurisdiction where the nature and extent of its business and properties require
the same, and (c) possesses all requisite corporate authority and power to
conduct its business and execute, deliver, and comply with the terms of each of
the Transaction Documents, the Dobson Acquisition Documents, and the Sygnet
Merger Documents to which such Company 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.

     2.   Each Company has duly executed and delivered each Transaction Document
and each Sygnet Merger Document, to which such Company is a party.

     3.   Each Transaction Document and Sygnet Merger Document to which any
Company is party evidence the valid and legally binding obligations of such
Company, enforceable against such Company 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).

     4.   The execution, delivery, and performance of and compliance with the
terms of the Transaction Documents and the Sygnet Merger Documents will not
cause any Company to be in violation of its respective Articles or Certificates
of Incorporation or Bylaws.

     5.   The execution, delivery, and performance of and compliance with the
terms of the Transaction Documents and the Sygnet Merger Documents will not
cause 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 Sygnet Merger Documents will not
cause any Company to be in default under any material, written, or oral
agreements, contracts, commitments, or understandings to which any Company is a
party.

     7.   Each Company is in compliance in all material respects with all
applicable Laws, federal, state, and local (including without limitation,
Environmental Laws and those statutes administered each state public utility
commission that, on the date of this opinion, exercises jurisdiction over the
Companies (collectively, the "LOCAL AUTHORITIES")), 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 Sygnet Merger Documents.

     8.   No Company is involved in, nor are we aware of the threat of, any
Litigation which is reasonably likely to be determined adversely to any Company.
There are no outstanding orders or judgments for the payment of money in excess
of $1,000,000 (individually or collectively) or any warrant of attachment,
acquisition, or similar proceeding against any Company's assets having a value
(individually or collectively) of $1,000,000 or more.


                                       2                            EXHIBIT G-1
<PAGE>

     9.   The extent of the ownership of the capital stock of or equity interest
in, and jurisdiction of organization of, each Company is as set forth on ANNEX A
attached hereto, and, to the best of our knowledge, after reasonable
investigation, EXCEPT as set forth on such schedule, no Company (a) has any
other Subsidiaries or (b) has transacted business under any other corporate or
trade name in the five-year period preceding the date hereof.

     10.  No Company, and no Affiliate of any Company, is (a) subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Investment Company Act of 1940 (as any of the preceding acts have
been amended), or any other Law (other than regulations issued by the FCC and
REGULATION X of the Board of Governors of the Federal Reserve System) which
regulates the incurring by any Company of Debt, including, but not limited to,
Laws relating to common or contract carriers or the sale of electricity, gas,
steam, water, or other public utility services, or (b) EXCEPT as listed on
ANNEX B attached hereto, a "UTILITY" defined in the Laws of the jurisdictions in
which such Company or such Affiliate maintains assets or conducts business.

     11.  The proceeds of the Borrowings are not to be used directly or
indirectly for the purpose of purchasing or carrying, or for the purpose of
extending credit to others for the purpose of purchasing or carrying, any
"MARGIN STOCK" as that term is defined in REGULATION U of the Board of Governors
of the Federal Reserve System.  

     12.  (a) No Employee Plan has incurred an accumulated funding deficiency
(as defined in the Code and ERISA), (b) no Company, and no ERISA Affiliate of
any Company, has incurred material liability which is currently due and remains
unpaid to the PBGC or to an Employee Plan in connection with any such Employee
Plan, (c) no Company, and no ERISA Affiliate of any Company, has withdrawn in
whole or in part from participation in a Multiemployer Plan, (d) no Company has
engaged in any prohibited transaction (as such term is defined in ERISA or the
Code) which would be a Material Adverse Event, and (e) to the best of our
knowledge, after reasonable investigation, no Reportable Event has occurred
which is likely to result in the termination of any Employee Plan.

     13.  The interest payable by Borrower pursuant to the Notes and Credit
Agreement is not in violation of the usury Laws of the State of Texas or the
United States of America.

     14.  The conditions precedent to the initial Borrowing have been waived in
writing or satisfied in accordance with the Loan Papers.

     15.  Borrower is the beneficial and record owner of all shares of Sygnet
Communications, Inc., free and clear of any Liens or transfer restrictions.

     16.  The Financing Statements are in sufficient form for recordation.  When
the Financing Statements have been filed and recorded in the jurisdictions
listed on ANNEX A hereto, the Transaction Documents shall create and perfect
valid and continuing security interests in favor of Administrative Agent, for
the benefit of Lenders in the Collateral, to the extent that the filing of
financing statements is effective to perfect security interests in the
Collateral, subject to the qualifications set forth in the Security Agreements
with respect to licenses issued by the FCC.  No further action, including any
filing or recording of any document, is necessary in order to establish,
perfect, and maintain Lenders' security interests in the assets and the stock
created by the Security Agreements, EXCEPT for the periodic filing of
continuation statements with respect to financing statements filed under the
Uniform Commercial Code of the applicable jurisdiction.


                                       3                            EXHIBIT G-1
<PAGE>

     17.  The Dobson Acquisition Documents have been duly executed and delivered
by DOC and D/S Company, and constitute the valid and legally binding obligations
of DOC and D/S Company, 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 Dobson Acquisition has been consummated in accordance with the
Dobson Acquisition Documents and applicable Law.

     RE:   CREDIT AGREEMENT FOR DOBSON/SYGNET OPERATING COMPANY

Ladies and Gentlemen:

     We have acted as special communications regulatory counsel to 
Dobson/Sygnet Operating Company (together with is its successor by merger, 
Sygnet Wireless, Inc., "BORROWER"), and its Subsidiaries (collectively with 
Borrower, the "COMPANIES") in connection with the Credit Agreement, dated as 
of December 23, 1998 (as amended, modified, supplemented, or restated from 
time to time, the "CREDIT AGREEMENT"), among Borrower, NationsBank, N.A., as 
Administrative Agent, Lehman Commercial Paper Inc. and PNC Bank, National 
Association, as Co-Syndication Agents, Toronto Dominion (Texas), Inc. and 
First Union National Bank, as Co-Documentation Agents, and Lenders named on 
SCHEDULE 2.1 to the Credit Agreement ("LENDERS").  

     This opinion is delivered pursuant to SECTION 7.1 of the Credit 
Agreement and PARAGRAPH 12 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.

     We have examined the articles of incorporation, bylaws, and partnership 
agreements, as applicable, of the Companies, the Loan Papers, the 
certificates of public convenience and necessity and similar authorizations 
issued to the Companies by the Federal Communications Commission ("FCC") and 
each state public utility commission ("PUC") that, on the date of this 
opinion, exercises jurisdiction over the Companies (each such PUC, an 
"APPLICABLE PUC").  See SCHEDULE I for the list of Applicable PUCs 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. Section 151 ET SEQ. (the 
"COMMUNICATIONS ACT"), and all laws administered by, and all rules, 
regulations, and published policies of, the FCC and Applicable PUCs, and we 
express no opinion and assume no responsibility as to the applicability of 
any other laws.

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

     1.   The consummation of the Sygnet Merger and the execution and 
delivery of the Credit Agreement and the Loan Papers by Borrower and the 
performance by the Companies of the Obligation will not violate any law, 
rule, regulation, or policy of the FCC or any Applicable PUC.

                                                                   EXHIBIT G-2
<PAGE>

     2.   The execution and delivery of a Guaranty by the Subsidiaries party 
thereto and the performance by such 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 operation, in accordance with the Communications Act and the PUC Laws, of 
each of the cellular systems owned or leased by the Companies (collectively, 
the "CELLULAR SYSTEMS").  All of the 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 Papers and the Sygnet Merger 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]
 .

     5.   The ownership and operation by the Companies of their Systems and 
other business operations 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 Sygnet Merger, the execution and delivery of the Loan 
Papers, 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 Papers.

     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, complaint, inquiry, or investigation before 
the FCC or any Applicable PUC (i) relating to any Company or relating to its 
Cellular 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 Cellular Systems or business operations or 
(ii) seeking to prohibit, restrict, or delay consummation of the transactions 
contemplated by the Loan Papers, the Sygnet Merger Documents, or fulfillments 
of any conditions under the Loan Papers of the Sygnet Merger 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 Cellular Systems or business operations.

     This opinion letter is provided to Administrative Agent, Syndication 
Agent, Documentation Agent, each Lender, and Haynes and Boone, LLP, and their 
respective participants, assignees, or other transferees, by us in our 
capacity as special communications regulatory counsel to the Companies.

                                        Very truly yours,

     RE:   CREDIT AGREEMENT FOR DOBSON/SYGNET OPERATING COMPANY

Ladies and Gentlemen:

     We have acted as special [                           ] counsel to 
Dobson/Sygnet Operating Company (together with its successor by merger, 
Sygnet Wireless, Inc., "BORROWER"), and its Subsidiaries (collectively with 
Borrower, the "COMPANIES") in connection with the Credit Agreement, dated as 
of December 23, 1998 (as amended, modified, supplemented, or restated from 
time to time, the "CREDIT AGREEMENT"), between Borrower, NationsBank, N.A., 
as Administrative Agent, Lehman Commercial Paper Inc. and PNC Bank, National 
Association, as Co-Syndication Agents, Toronto Dominion (Texas), Inc. and 
First Union National Bank, as Co-Documentation Agents, and Lenders named on 
SCHEDULE 2.1 to the Credit Agreement ("LENDERS").  

     This opinion is delivered pursuant to SECTION 7.1 of the Credit 
Agreement and PARAGRAPH 13 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.

     As to matters of law in the State of Ohio (the "SUBJECT JURISDICTION"), 
we have acted as your special counsel in connection with the preparation of 
the Credit Agreement and related Loan Papers.  In that connection, we have 
examined such certificates of public officials and of officers of Borrower, 
other documents, and matters of law as we deemed necessary or appropriate, 
including, without limitation, originals or copies of the Loan Papers and the 
opinions hereinafter stated, and counterparts of the following documents 
(collectively, the "TRANSACTION DOCUMENTS"):

          (a)   Credit Agreement;

          (b)   Guaranty executed by Sygnet Communications, Inc.;

          (c)   Pledge, Assignment, and Security Agreement naming Borrower, as
     Debtor, and Administrative Agent, as Secured Party;

                                                                   EXHIBIT G-3
<PAGE>

          (d)   Pledge, Assignment, and Security Agreement (collectively with
     (c) above, the "SECURITY AGREEMENTS") naming Sygnet Communications, Inc.,
     as Debtor, and Administrative Agent, as Secured Party;             

          (e)   Financing Statements showing Borrower, as Debtor, and
     Administrative Agent, as Secured Party, to be filed in appropriate
     jurisdictions in the State of Ohio;

          (f)   Financing Statements (collectively with (e) above, the
     "FINANCING STATEMENTS") showing Sygnet Communications, Inc., as Debtor, and
     Administrative Agent, as Secured Party, to be filed in appropriate
     jurisdictions in the State of Ohio;

          (g)   The Sygnet Merger Documents.

     Based on the foregoing, subject to the comments and exceptions 
hereinafter stated, and limited in all respects to the laws of the Subject 
Jurisdiction and the United States of America, it is our opinion that:

     1.   Each Company (a) is a corporation validly existing and in good 
standing under the Laws of its state of incorporation, (b) is duly qualified 
to transact business as a foreign corporation in each jurisdiction where the 
nature and extent of its business and properties require the same, and (c) 
possesses all requisite corporate authority and power to conduct its business 
and execute, deliver, and comply with the terms of the Transaction Documents 
and the Sygnet Merger Documents to which such Company 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.

     2.   The Loan Papers and the Sygnet Merger Documents to which any 
Company is a party evidence the valid and legally binding obligations of such 
Company, enforceable in accordance with their respective 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).

     3.   Each Company has duly executed and delivered each Loan Paper and each
Sygnet Merger Document, to which such Company is a party.

     4.   The execution, delivery, and performance of and compliance with the 
terms of the Loan Papers and the Sygnet Merger Documents will not cause any 
Company to be in violation of its respective Articles or Certificates of 
Incorporation or Bylaws.

     5.   To the best of our knowledge, after reasonable investigation, no 
Company is, nor will the execution, delivery, the performance of, and 
compliance with the terms of the Loan Papers and the Sygnet Merger Documents 
(and the Sygnet merger contemplated thereby) cause 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 Security Agreements and Financing Statements are in proper
recordable form, and constitute valid and binding obligations of the Companies
executing the same enforceable in accordance with their terms, EXCEPT as the
enforcement thereof may be limited by applicable bankruptcy, rearrangement,
receivership, reorganization, or similar Debtor Relief Laws from time to time in
effect and affecting the rights of creditors generally, 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 Financing Statements are legally sufficient under the laws of
the Subject Jurisdiction to perfect any security 

                                       2                           EXHIBIT G-3
<PAGE>

interests in favor of Administrative Agent, for the benefit of Lenders,  
which may have attached to the Collateral therein described.

     7.   Under the laws of the Subject Jurisdiction, no mortgage, 
documentary, stamp, or similar taxes, other than nominal recording fees, will 
be payable in connection with the execution, delivery, or recording of the 
Transaction Documents or any of the transactions contemplated thereby.

     8.    The Financing Statements should be filed with the Secretary of 
State of                       and with                                    at 
the addresses set forth on SCHEDULE 1 hereto.  When so filed and recorded, 
the Transaction Documents shall create and perfect a valid and continuing 
security interest in the Collateral described in the Transaction Documents, 
to the extent that the filing of a financing statement in the Subject 
Jurisdiction is effective to perfect the security interests granted in the 
Collateral in favor of Administrative Agent, for the benefit of Lenders.  No 
further or subsequent filing, recording, or registration of the Transaction 
Documents or any other instrument will be necessary in order to create, 
perfect, or maintain the liens and security interests created an perfected by 
the Transaction Documents, EXCEPT that within six months next prior to the 
expiration of five years from the filing of the Financing Statements (and 
each five years thereafter), Continuation Statements must be filed with the 
Secretary of State of                   , all pursuant to the Uniform 
Commercial Code as enacted in the Subject Jurisdiction.

                      FORM OF AFFILIATE SUBORDINATION AGREEMENT

     THIS AFFILIATE SUBORDINATION AGREEMENT is entered into among NationsBank,
N.A., in its capacity as Administrative Agent for Lenders (defined below), and 
________________, a __________________ corporation ("SUBORDINATED CREDITOR"),
and Dobson/Sygnet Operating Company (including its successor by merger, Sygnet
Wireless, Inc.) ("BORROWER").

     WHEREAS, Borrower, NationsBank, N.A., as Administrative Agent, Lehman
Commercial Paper Inc. and PNC Bank, National Association, as Co-Syndication
Agents, Toronto Dominion (Texas), Inc. and First Union National Bank, as
Co-Documentation Agents, and certain Lenders have entered into a Credit
Agreement, dated as of December 23, 1998 (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 Papers, and the execution and delivery thereof is a condition precedent to
Lenders' obligations to extend credit under the Loan Papers;

     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 either of the Credit Agreements 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). 


                                                                     EXHIBIT H

<PAGE>

     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:
          (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 appoint
     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 the 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. 


                                                                     EXHIBIT H

<PAGE>

     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 Papers 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 Loan Papers 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 


                                                                     EXHIBIT H

<PAGE>

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 CONSTRUED ACCORDING TO THE LAWS OF
THE STATE OF TEXAS.

     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 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.

                                       Re:  12 1/4% Senior Notes due 2008

Ladies and Gentlemen:

    We have acted as special counsel to Dobson/Sygnet Communications Company 
(the "Company") in connection with the issuance and sale of $200,000,000 
aggregate principal amount of the Company's 12 1/4% Senior Notes due 2008 
(which are referred to herein as the "Old Notes") and the registration under 
the Securities act of 1933 of $200,000,000 aggregate principal amount of the 
Company's 12 1/4% Senior Notes due 2008 (the "New Notes"). The New Notes are to 
be offered in exchange for all outstanding Old Notes (the "Exchange Offer") as 
more fully set forth in the prospectus which forms are a part of the Company's 
Registration Statement on Form S-4 (the "Registration Statement") with which 
this opinion is being filed.

    In this connection we have examined the Company's Certificate of 
Incorporation and Bylaws, minutes of certain meetings of the Company's Board 
of Directors and the Indenture dated as of December 23, 1998 between the 
Company and United States Trust Company of New York, as Trustee, governing 
the Old Notes and the New Notes, and have made such other investigations of 
fact and law as we deem necessary to render the opinions set forth herein.

    Based on the foregoing, we are of the opinion that the New Notes to be 
exchanged for the Old Notes in the Exchange Offer, when issued in accordance 
therewith, will be legally issued, fully paid and non-assessable and will be 
binding obligations of the Company.

    The opinion expressed herein as to the New Notes constituting binding 
obligations of the Company is subject to the exceptions that (1) enforcement 
may be limited by bankruptcy, insolvency (including, without limitation, all 
laws relating to fraudulent transfers), reorganization, moratorium or similar 
laws affecting enforcement of creditors rights generally, and (2)

<PAGE>

enforcement is subject to general principles of equity (regardless of whether 
enforcement is considered a proceeding in equity or at law).

    We hereby consent to the reference to our firm in the Prospectus under 
the caption "Legal Matters".

                                       Very truly yours,


                                       /s/ McAFEE & TAFT

reasonably deem necessary or appropriate to enable Buyer to exercise fully 
its rights hereunder.

     3.   CLOSING DATE.  Seller and Buyer agree that the closing with respect 
to this Agreement shall take place simultaneous with the closing of that 
certain Agreement and Plan of Merger dated as of July 28, 1998, among Sygnet

obtain any required consent of a third party within sixty (60) days of the 
Closing Date, the Buyer may, in its sole election, re-convey to Seller any of 
the Assets subject to a lien, encumbrance, security interest or claim of 
third parties for a credit equal to the fair market value of the returned 
Asset, such value to be determined by Seller and Buyer. 

     6.   REPRESENTATIONS OF BUYER.  Buyer represents and warrants to Seller 
that (a) Buyer has full power, authority and capacity to execute this 
Agreement and perform the transactions required of it to consummate the 
transaction; (b) Buyer's execution, delivery and performance of this 
Agreement, and the execution and delivery of the documents delivered and

     This Master Site License Agreement ("Agreement") is entered into as of 
the 23rd  day of  December , 1998, by and between Dobson Tower Company, an 
Oklahoma corporation (referred to herein as "Licensor") and Sygnet

("FCC") to construct and operate communications systems throughout the United 
States.

     R-2.  Licensor owns, leases, operates and/or manages real estate, 
buildings, towers, tanks and/or other improvements ("Improvements") on real 
property (each a "Property") in the United States and wishes to License 
portions of a number of the Properties to Tenant for the purpose of locating 
and operating communications facilities' and services thereon.

     R-3.  Tenant desires to license from Licensor portions of such 
Properties for such purpose.

     NOW, THEREFORE, for good and valuable consideration, the receipt and

follows:

     1.   MASTER LICENSE.

     (A)  This Agreement sets forth the basic terms and conditions upon which 
each such Property or portion thereof is licensed by Licensor to Tenant.  
Upon the parties' agreement as to the particular terms of any such license, 
the parties shall execute and attach hereto a completed site license ("Site 
License") for each such site, in the form attached hereto as Exhibit A, which 
is incorporated herein by this reference.  The terms and conditions of any 
Site License shall govern and control in the event of a discrepancy or 
inconsistency with the terms and conditions of this Agreement.  This 
Agreement shall govern Licensor's existing Properties only, and shall not 
apply to raw land or new construction of towers on such Properties.

     (B)  Upon execution hereof, Licensor agrees to provide Tenant with such 
information regarding each Property which it operates as may be necessary for 
Tenant to evaluate the usefulness of such Property for its purposes as may be 
readily available to Licensor.  Licensor agrees to use reasonable efforts to 
cause each of its subsidiaries and managers at each such Property to 
cooperate fully with Tenant and its agents for the purpose of determining 
suitability of the Property and installing and constructing the Tenant's 
facilities, including providing Tenant and such agents with access to such 
Properties and the opportunity to conduct limited testing at any such 
Property, subject to reasonable limitations imposed by Licensor and/or any of 
such managers.

attached to each affected Site License as Exhibit 6.  Upon reasonable request 
of Tenant, Licensor shall exercise its best commercially reasonable efforts 
to obtain the written consent of the prime landlord to the Site License and 
any renewals or extensions thereof.  The part of the Property to be licensed 
by Licensor to Tenant shall include ground and/or rack space and such other 
space for the mounting of antennas for the operation of certain 
telecommunications equipment to be located within, atop, adjacent to or on 
the Property, and such space across the Property that might be required for 
providing Tenant access and necessary utilities.  All floor space, rack 
space, ground space, tower space and associated real property licensed by 
Licensor to Tenant shall collectively be referred to hereinafter as "the 
Premises," as more fully described in Exhibit 2 to the Site License.  A more 
complete description of the equipment to be placed on the Premises by Tenant, 
including all transmit and/or receive frequencies, dimensions, and more 
specific positions of such equipment as it will be installed on the Premises 
shall be attached to each Site License at Exhibit 1. Tenant shall prepare and 
present to Licensor an accurate and complete Exhibit 1 prior to execution of 
the Site License for the subject Property.  If, during the term of the Site 
License, Tenant requests to add or remove equipment to or from the Premises, 
which additional equipment is not listed on Exhibit 1, Licensor shall use all 
reasonable efforts to accommodate Tenant's request, provided that the 
Property has sufficient space and capacity to support the requested 
additional equipment.  In the event of such an agreed upon increase or 
decrease in the equipment at the Premises, Licensor and Tenant shall mutually 
agree to a reasonable rental adjustment as consideration for such additional 
or reduced equipment.

     To the extent any rights herein are subject to any existing Prime Lease 
or license granted or existing in favor of Licensor from a third party 
("third party license"), the rights herein are expressly made subject to such 
third party license.  In the event any such Prime Lease or other third party 
license terminates or expires by its terms prior to the times for termination 
or expiration or the Term herein, or the two additional optional renewal 
terms herein, within ninety (90) days after execution of this Master Site 
License Agreement, Licensor agrees to begin exercising its best commercially 
reasonable efforts to obtain such renewals or extensions thereof, and options 
for renewal or extensions thereof, as Licensor is reasonably able, and on as 
nearly similar terms and rental sums as are now in existence, in order for 
Licensor to be able to fulfill the terms of this Agreement, for the entire 
duration envisioned herein.  In the event Licensor is able to negotiate such 
renewals or replacements thereof, but any of the material terms will be 
different (including 

                                       2

<PAGE>

but not limited to rental sums), Licensor shall present same to Tenant for 
its review and approval, before Licensor executes same.

     Licensor shall also be responsible, at its expense, for the cost of 
obtaining any approvals which may be required by any local, state or federal 
authority, in conjunction with the granting of any License created herein, 
its ownership of the Property and Improvements, or the operation of the 
License granted herein, except insofar as same is specifically required of 
Tenant by law in order for Tenant to carry out its intended use on the 
Premises.

     3.   TERM AND TERMINATION.  Each Site License shall become effective 
upon installation of Tenant's equipment at the subject Property or 120 days 
following the date the Site License for such Property is fully executed, 
whichever is sooner ("the Commencement Date"), and shall continue in effect 
for a term of five (5) years.  Tenant warrants that it shall employ 
reasonable efforts to obtain all required local permits for construction and 
operation of its facilities installed by or owned by Tenant, and shall inform 
Licensor immediately of its receipt of those permits.  Tenant shall provide 
Licensor with prior notice of the date upon which Tenant shall commence the 
installation of Tenant's equipment.  It is expressly understood that all 
rights granted to Licensee for each Property hereunder are irrevocable until 
the Site License for such Property expires or sooner terminates in accordance 
with the terms and conditions herein set forth.

     If, at any time during the Term hereof, (including any renewal or 
extension of the Term herein), Tenant shall lose its F.C.C. license needed 
for it to use the Premises for the intended use under the License granted 
herein (as distinguished from any transfer, sale or assignment of such F.C.C. 
license), this lease shall immediately terminate upon the termination of 
Tenant's F.C.C. license, and at that point, no further obligation shall be 
owed by either party hereto to the other under this Agreement, except as to 
obligations which had already accrued prior to the time of the loss of such 
Tenant F.C.C. license.

     (A)  Following an uncured material breach by a party, the non-breaching 
party may terminate the applicable Site License, provided, however, the 
non-breaching party must first provide to the breaching party all reasonable 
opportunity provided hereunder to cure any such breach, including providing 
to the breaching party at least thirty (30) days prior written notice of the 
non-breaching party's intent to terminate the Site License.  Upon termination 
or expiration of a Site License, Tenant shall immediately remove its 
equipment from Licensor's Premises.  Tenant's failure to remove its equipment 
within thirty (30) days following the expiration or termination of the Site 
License shall entitle Licensor to receive from Tenant storage fees in an 
amount equal to one hundred dollars ($100) per day beyond such thirty (30) 
day period.  Licensor hereby 

                                       3

<PAGE>

waives any and all landlord liens or similar claims to Tenant's equipment, 
which equipment may be removed by Tenant at any time, provided, however, such 
removal shall not create any termination of the applicable Site License or 
reduction in any amount due Licensor.

     (B)  Any of Tenant's equipment which is deemed stored by Licensor in 
accord with the terms herein shall not be entitled to receive electrical 
power during such period of storage and Licensor shall have the right to 
discontinue power to all stored equipment.  Such equipment may also be 
removed from the Premises by Licensor and stored at Licensor's main 
facilities, but at all times remain the property of Tenant.

     (C)  In the event that the Premises are damaged or destroyed such that 
Tenant is unable to operate its equipment thereon, Licensor shall make an 
election within ten (10) days following such event as to whether Licensor 
shall make repairs or reconstruct the damaged portion of the Premises to 
enable Tenant to operate upon the Premises in substantially the same manner 
as Tenant enjoyed prior to the event of destruction.  Such election shall 
only be effective if Licensor is willing and able to make such repair or 
reconstruction within ninety (90) days following the making of the election.  
If Licensor elects not to repair or reconstruct the Premises within the 
aforementioned ten (10) day period; or if Licensor is unable to make such 
repairs or reconstruct the Premises during that ninety (90) day period, then 
Tenant shall have the option to:  1) terminate the Site License, without 
further liability to either party, or 2) require Licensor to immediately pay 
over, or assign its right to payment of all insurance proceeds payable to 
Licensor arising from the loss or damage to the Premises, and Tenant may use 
such proceeds to make such repairs or reconstruction.  If Licensor elects to 
repair or reconstruct the Premises within the aforementioned ninety (90) day 
period, or if Tenant elects to use the insurance proceeds to repair or 
restore said damage, the Site License shall continue to bind the parties, 
providing, however, Licensor shall not be entitled to receive rents during 
the period commencing on the date of destruction and extending to the date of 
completion of the repairs or reconstruction.  In the event that Tenant 
terminates the applicable Site License under this Paragraph 3(C), Licensor 
shall return to Tenant all prepaid rents collected by Licensor which 
represents that period commencing upon the date of destruction of the 
Premises and continues to the date of termination.  Licensor's failure to 
make an election during the ten (10) day period following damage or 
destruction of the Premises shall be deemed an election by Licensor not to 
repair or reconstruct the Premises.  Nothing contained herein shall be deemed 
an election by Licensor not to repair or reconstruct the Premises.  Nothing 
contained herein shall be deemed a guarantee by Licensor to repair or 
reconstruct the Premises following destruction.

                                       4

     4.   MAINTENANCE OF EQUIPMENT.  Tenant shall, at its own expense, 
maintain its equipment on or attached to the Premises in a safe condition and 
in good repair, and in a manner reasonably suitable to Licensor so as not to 
conflict with the use of the Property by Licensor or by any other tenant 
lawfully using the Property, subject to Paragraph 19 below.  All repair and 
maintenance of Tenant's equipment shall be performed by qualified 
technicians, authorized to enter the Premises as Tenant's agents, contractors 
or employees.

     To the extent any of the Improvements or the Premises are required to be 
repaired or maintained under any laws or regulations of the F.C.C., or the 
F.A.A. (including but not limited to tower signage, painting and lighting 
requirements), such maintenance and repairs shall be promptly addressed by 
Licensor at its sole expense, and in accordance with any such legal 
requirements.

     (A)  Any and all machinery, equipment and trade fixtures, except the 
electrical service, installed by Tenant, shall remain Tenant's 
notwithstanding the fact that it may be affixed or attached to the realty or 
the Premises, and shall, during the term of the Site License or any extension 
or renewal thereof, and upon termination thereof, belong to and be removable 
by Tenant.  Tenant agrees that the Premises and associated realty shall not 
be damaged by Tenant's occupancy and that Tenant shall, upon termination of 
occupancy, make any repairs necessitated by Tenant's occupancy or removal of 
Tenant's equipment, less ordinary wear and tear and loss by casualty or other 
causes beyond Tenant's control.

     (B)  All transmitters operated by Tenant upon the Premises shall include 
the use of, for example, a single stage isolator or a single bandpass cavity 
or such other devices which may reasonably prevent or deter the creation of 
harmful electrical interference.  Licensor may determine, from time to time 
and as is reasonable and necessary, other similar requirements for safe, 
interference free operation of Tenant's equipment upon the Premises and 
Tenant shall comply with all such requests.

     5.   ACCESS.  Licensor agrees to give Tenant free and unrestricted 
ingress and egress to the Premises during the term of the Site License and 
any extension or renewals thereof for the purpose of installing, maintaining, 
operating, replacing, upgrading and removing Tenant's equipment.  Licensor's 
promise does not extend to real property which is not under Licensor's 
authority or control. Licensor's promise will not be interpreted as a 
guarantee of Tenant's ability to enter or exit the Premises when weather 
conditions, road conditions and other elements outside of Licensor's control 
might affect Tenant's ability to enter the 

                                       5

<PAGE>

Premises.

     6.   MAINTENANCE AND OPERATION OF PREMISES.  Licensor reserves to itself 
and its successors, and assigns, the right to maintain the Property and to 
operate telecommunications facilities thereon in such manner as will best 
enable each to fulfill its own requirements, but in accord with the covenants 
contained herein, including Licensor's promise to maintain the Property in 
merchantable condition.  In such event, Licensor shall not act, or permit 
others to act, under such reserved rights in such a manner as to cause any 
interruption of or interference with Tenant's operation of Tenant's 
equipment, or the rights granted under this Agreement, or Tenant's service, 
including but not limited to electrical interference and interference created 
by intermodulation.  Under no circumstances shall Licensor be liable for 
consequential damages to any party, including but not limited to third 
parties, arising out of interruption of Tenant's service, except as a result 
of acts or omissions by Licensor, or those acting under authorization from 
Licensor.

     (A)  Licensor shall be solely responsible at its expense for compliance 
with ally local, state and federal laws, regulations and rules, involving 
painting, signage and lighting requirements arising out of owning, 
maintaining, or operating of the Improvements or the Property, in accord with 
the existing laws, rules and regulations adopted, or which might be adopted, 
including those by the Federal Aviation Administration or the Federal 
Communications Commission; and shall indemnify Tenant for all fines levied 
against Tenant for Licensor's failure to comply with such laws, rules and 
regulations.

     (B)  Tenant promises to cooperate fully in Licensor's efforts to 
maintain the peaceful occupation of the structure of which the Premises are a 
portion, including, without limitation, Tenant's agreement to cooperate in 
maintaining the cleanliness of the Premises; in constructing its equipment in 
a safe, reasonably quiet, and non-disruptive manner; in assisting in 
maintaining the security of the Premises by reasonably limiting the number of 
persons with access to the Premises; and in directing its employees to treat 
all other tenants with civility and courtesy.

     (C)  In the event that Licensor deems it reasonable and necessary, 
Licensor may, at Licensor's expense, require that an intermodulation study be 
performed by Tenant, to determine the effect of Tenant's use of the Premises 
as it might effect existing users of the Property; provided that Licensor may 
only require Tenant to do such study one (1) time during the term of a Site 
License. Licensor may require that Tenant present to Licensor such study as a 
condition to Tenant's occupation.

     (D)  Licensor hereby warrants that the Premises have been 

                                       6

<PAGE>

constructed and will be operated and maintained in accord with all laws, 
rules, statutes, and regulations adopted or to be adopted by all applicable 
and relevant fora or governmental bodies.  Subject to the terms and 
conditions contained herein, Licensor hereby agrees to indemnify and hold 
Tenant harmless for all violations of any law, rule, statute, or regulation 
for which Licensor is responsible, including the payment of all fines, 
forfeitures, or similar penalties levied against Tenant for Licensor's 
violation of its duties hereunder, provided, however, Licensor's obligation 
to indemnify and hold Tenant harmless in accord with this Paragraph 6(D) 
shall be limited by those expressed conditions and limitations contained 
herein, including, without limitation, Tenant's compliance with all of its 
duties created hereunder.

     7.   RENTAL OF PREMISES. Tenant shall pay Licensor monthly rent in the 
amount set forth in the Site License for the subject Property (plus 
applicable taxes), payable in advance commencing on the Commencement Date of 
the License as provided for in Paragraph 3 and on the first day of each month 
thereafter during the term of the Site License or any renewal period.  All 
rental payments will be made to Licensor, at the following address:

          Dobson Tower Company
          13439 N. Broadway Extension, Suite 200
          Oklahoma City, OK 73114

Tenant agrees to pay a late fee for all rent payments not timely made (ten 
(10) days past due) in an amount equal to five percent (5%) of the overdue 
amount.

     (A)  If, following ten (10) days prior written notification to Tenant by 
Licensor of Tenant's failure to make current its account, Tenant fails to 
make timely rent payments such that the account is greater than sixty (60) 
days past due, Tenant shall be deemed to have materially breached this 
agreement. Notwithstanding all other remedies available at law or equity or 
contained herein, Tenant's breach under this Paragraph 7(A) shall entitle 
Licensor to demand and collect from Tenant a penalty amount in the amount set 
forth in the Site License, in addition to all amounts due hereunder.

     (B)  Upon each anniversary date of the Commencement Date as defined by 
Paragraph 3 herein, the annual charge for rental of the Premises shall be 
automatically increased by an amount equal to four percent (4%) of the 
previous annual rate.  Such increases shall be automatic and will not require 
Tenant's prior approval and by its execution of this agreement, Tenant agrees 
to pay each such increase as a portion of its rent.  Such increases shall 
apply to the entire term of this agreement and any extension or renewal 
period.

                                       7

<PAGE>

     (C)  All rental payments made to Licensor shall be deemed the sole and 
exclusive property of Licensor and shall not be subject to delay, offset, 
refund or placement in escrow for any reason or purpose, except such refunds 
as are expressed herein.

     8.   INDEMNIFICATION AND INSURANCE.  Tenant shall indemnify Licensor 
against any and all claims and demands for damages to property and injury or 
death to persons, arising out of or caused by the installation, maintenance, 
presence, use or removal of Tenant's equipment on the Premises, unless such 
damage or injury shall be due to the willful acts or negligence of Licensor, 
its employees, agents or invitees.  Licensor shall indemnify Tenant against 
any and all claims and demands for damages to property and injury or death to 
persons, arising out of or caused by the acts or omissions of Licensor or 
Licensor's employees, agents, or invitees, or the installation, maintenance, 
presence, use or removal of third party's equipment on the Property, unless 
such damage or injury shall be due to the negligence of Tenant, its 
employees, agents or invitees.  Licensor and Tenant shall each obtain and 
maintain public liability insurance in an amount equal to Two Million Dollars 
($2,000,000) during the term of the Site License and any renewal period, 
respectively covering Licensor's and Tenant's use and ownership of rights in 
the Premises.  Tenant shall cause Licensor to be named as an additionally 
insured person on its casualty and public liability policy(ies), and Licensor 
shall cause Tenant, and any Tenant lender or lenders, to each be named as 
additionally insured persons on Licensor's casualty and public liability 
policy(ies).  Tenant shall also carry worker's compensation insurance 
covering all of Tenant's employees and automobile insurance covering all of 
Tenant's vehicles in such amounts as are required by law.  Certificates of 
required insurance shall be periodically furnished to Licensor by Tenant, and 
to Tenant by Licensor upon reasonable demand by the requesting party.

     (A)  Tenant and Licensor shall each be responsible for maintaining any 
insurance covering their own equipment on the Property, in commercially 
reasonable amounts sufficient to assure the ability to repair, reconstruct or 
replace same if destroyed; the lives and health of their respective agents, 
employees and invitees; damage or injury to other persons or other persons' 
property caused by the acts or omissions of their own agents, employees, or 
invitees; and any other business or liability insurance which each may deem 
necessary to protect their own interests.

     While not required to do so under this Agreement, in the event Tenant 
obtains business interruption insurance, Licensor shall have no claim of 
right, title or interest in or to any benefits paid under such coverage for 
any reason.

     (B)  Licensor and Tenant each hereby waive any and all rights 

                                       8

<PAGE>

of recovery, claim, action, or causes of action, against the other, its 
agents, officers or employees, for any loss or damage that may occur to the 
Premises, or any improvements thereto, or any personal property of such party 
therein, or to any person by reason of fire, the elements or any other cause 
which could be insured against under the terms of standard property, 
liability, fire and extended coverage insurance policies, regardless of cause 
or origin, including negligence of other party hereto, its agents, officers 
or employees and each party covenants that no insurer shall hold any right of 
subrogation against such other party.

     (C)  Hold Harmless:  Tenant hereby agrees to hold harmless the owner of 
the real property and associated structures and all persons from whom 
Licensor has taken authority for the purposes of Licensor's entrance into and 
performance hereunder (if such person(s) are third parties), for any and all 
injury or damages arising out of Tenant's occupation, use or employment for 
commercial purposes of the Premises, including, without limitation, all 
injury, loss or damages to Tenant and its agents, assigns, successors, 
employees, invitees, and Tenant agrees that Licensor is the only other party 
to this agreement and that no other party shall be deemed to have any 
liability, duty or obligation to Tenant arising hereunder.

     9.   RENEWAL OPTIONS.  Tenant shall have the option to renew and extend 
the term of any Site License upon the same terms and conditions as set forth 
herein for two (2) successive period(s) of five (5) years each (the "Renewal 
Periods"). Tenant shall be deemed to have exercised its option to renew a 
Site License and such Site License shall automatically renew on each fifth 
year anniversary following commencement unless written notification of intent 
to terminate the Site License is received by Licensor from Tenant on a date 
which is at least ninety (90) days, but less than one hundred eighty (180) 
days prior to the date of expiration. The word "term" as used in this 
Agreement shall include the above-mentioned Renewal Period(s) as might be 
exercised by Tenant.

     10.  DEFAULT.  Neither party shall be deemed in default under a Site 
License until the other party has given the defaulting party at least thirty 
(30) days written notice of any default hereunder and the defaulting party 
has failed to cure the same within thirty (30) days after receipt of such 
notice; provided, however, that where such default cannot reasonably be cured 
in such thirty (30) day period and if the defaulting party shall proceed 
promptly to cure the same and prosecute such curing with due diligence, the 
time for curing such default shall be extended for such period of time as may 
be deemed necessary by the other party in its reasonable discretion to 
complete such curing.  Tenant's right to cure a default provided in this 
Paragraph 10 shall not apply to the timely payment of rents.

                                       9

<PAGE>

     (A)  Licensor will not, except in an emergency as shall be interpreted 
in Licensor's sole discretion, cure any alleged default by Tenant until after 
the expiration of thirty (30) days following Tenant's receipt of notice 
provided for herein and then only if Tenant has failed, during such period, 
to cure such default or perform such act.

     (B)  Licensor reserves the right to disconnect the electrical power to 
Tenant's equipment if, following notification by another user of the 
Property, or Tenant's agents or employees, or by notification by officials of 
the Federal Government, it is determined that operation of Tenant's equipment 
is causing injury or damage to other persons or users, subject to Paragraph 
19 below, or is in violation of law.  Such disconnection by Licensor shall 
not be performed without informing Tenant prior to Licensor's taking such 
action and without providing Tenant with an opportunity within seventy-two 
(72) hours following such notification (which notification shall be by 
telephone and followed immediately by written notice pursuant to the 
Paragraph 13 herein below), to cure immediately such problems or answer such 
allegations.  If, following notification to Tenant by Licensor, Tenant does 
not repair or disconnect Tenant's equipment within the aforementioned 
seventy-two (72) hour period, to discontinue continuing injury and/or damage 
to other persons or tenants, and Licensor reasonably deems such repair or 
disconnection necessary to protect Licensor or other persons, Licensor may 
disconnect the electrical power to Tenant's equipment, which act shall be 
without liability to Licensor and Licensor shall not be liable for any 
damages, loss of revenue, claims, or injuries caused by Licensor arising out 
of disconnection of Tenant's equipment, except such injury or damages caused 
by Licensor's negligence or willful actions, and only to the extent provided 
for herein.  Licensor warrants that the terms contained within this Paragraph 
10(B) are substantially similar and reflected within all other licenses 
entered into by Licensor for third parties' occupation and use of all or any 
part of the Property and shall be included in substantially similar form 
within future licenses entered into by Licensor for future tenants' use of 
all or any part of the Property.

     (C)  Tenant shall be deemed to be in default if Tenant causes to be 
placed upon its equipment or the Premises any unbonded mechanics' or 
materialmen's lien or encumbrance, which placement delays, prevents or 
impedes Licensor's or third parties' use of the Premises.  Notwithstanding 
the foregoing, Licensor acknowledges that Tenant has entered into a financing 
arrangement, including promissory notes and financial and security 
agreements, for the financing of Tenant's telecommunications facilities and 
the operation thereof.  Accordingly, Licensor hereby consents to Tenant's 
installation and operation of Tenant's equipment, which is deemed collateral 
under the aforementioned financing agreement(s), and Licensor agrees that (i) 
it disclaims any interest in the 

                                       10

<PAGE>

collateral, as fixtures or otherwise; and (ii) it shall hold as exempt such 
collateral from execution, foreclosure, sale, levy, attachment, or distress 
for any rent due or to become due and that such collateral may be removed by 
Tenant or pursuant to the terms of such financial arrangement(s) at any time 
without recourse to legal proceedings.  Licensor's consent provided under 
this Paragraph 10(C) shall not be employed for the purpose of reducing any 
obligation of Tenant's created hereunder for the timely payment of rents.

     11.  ASSIGNMENT OF LICENSE.  Tenant shall not assign or sub-license this 
Agreement or any Site License without the prior written consent of Licensor, 
EXCEPT that no prior written consent shall be required from Licensor for any 
such assignment or sub-license to (i) party who owns or acquires a 
controlling ownership interest in Tenant (whether by purchase of fifty-one 
percent (51%) or greater of the voting stock of Tenant, or substantially all 
of the assets of Tenant, or otherwise); (ii) Tenant's parent corporation or 
an affiliate of Tenant (For purposes of this paragraph, an affiliate is an 
entity in which there is a common owner owning at least a ten percent (10 %) 
ownership interest in both Tenant and the other affiliated entity, and shall 
include but not be limited to parent and subsidiary entities to Tenant, as 
well as partnerships in which Dobson Communications Corporation, or any of 
its subsidiary entities, is a general partner.); or (iii) a successor to 
Tenant's FCC license to operate Tenant's equipment.  In the event of a 
permitted assignment or sub-license which does not require Licensor's prior 
consent, Tenant shall provide Licensor written notice of the assignment or 
sub-license, and the name and address of the assignee or sub-licensee before 
same shall be binding on Licensor.  With regard to any assignment or 
sub-license which does require prior consent from Licensor, Licensor 
covenants and agrees that it will not unreasonably withhold, delay or 
condition its consent to any such assignment or sub-license.  Under no 
circumstances shall a Site License be assigned by Tenant to any party which 
does not agree to be bound by all terms and conditions contained herein.

     Licensor may assign its rights under this Agreement only upon sale of 
the underlying Property or Premises, and Licensor's Improvements, without 
prior approval from Tenant, PROVIDED that before the assignment may be made 
binding on Licensor or Tenant, Licensor's transferee shall furnish Tenant 
with the written adoption of this Agreement, and assumption of Licensor's 
obligations under this agreement.  Otherwise, no such assignment of the 
Licensor's rights under this Agreement shall be made without Tenant's prior 
written approval, which shall not be unreasonably withheld.

     (A)  As a condition precedent to Tenant's and Licensor's right to assign or
sub-license this Agreement and/or any Site 

                                       11

<PAGE>

License to any third party, Tenant and Licensor each covenant that they will 
notify the other in writing of their intent to make such assignment or 
sub-license and, in the event that Licensor's or Tenant's consent is not 
required or is deemed given hereunder, the transferring party shall provide 
to the other all documents reasonably required by the non-transferring party 
to assure that the assignee or sub-licensee agrees to be bound by all terms 
and conditions contained herein which bind the transferring party.

     (B)  Notwithstanding anything in this agreement to the contrary, 
Licensor hereby agrees to Tenant's assignment of this Agreement and any Site 
License to any financing entity, or agent on behalf of any financing entity, 
to whom Tenant (i) has obligations for borrowing money or in respect to 
guarantee thereof; (ii) has obligations evidenced by bonds, debentures, notes 
or similar instruments; or (iii) has obligations under or with respect to 
letters of credit, bankers acceptances and similar facilities or in respect 
of guarantees thereof. Further, Licensor agrees to execute such estoppel 
affidavits and other documents relating to this Agreement and the Site 
Licenses as may be reasonably requested by Tenant or Tenant's lender(s).

     12.  ATTORNEYS FEES.  In the event that either party brings a law suit 
to compel the performance of the other party hereunder, the substantially 
prevailing party in such suit shall be entitled, in addition to all other 
remedies at law or equity, to reimbursement for all reasonable attorney's 
fees and costs paid to bring or defend such suit.

     13.  MANNER OF GIVING NOTICE.  Any written notice to be given under this 
Agreement or any Site License shall be mailed to each party at the address 
shown below.  All notice shall be sent by registered or certified mail, 
postage prepaid, return receipt requested, or by a reputable express carrier 
which provides overnight delivery service following receipt of a signature 
from the receiver, and shall be deemed given when so mailed or sent.

                    13439 N. Broadway Extension, Suite 200
                    Oklahoma City, OK 73114

     14.  QUIET ENJOYMENT.  Licensor covenants and agrees that upon Tenant's 
paying the rent and other applicable charges and performing in accord with 
the terms and conditions stated herein, Tenant may peacefully and quietly 
enjoy the Premises, subject to the terms and conditions of this Agreement and 
the Site License.

     15.  COMPLIANCE WITH STATUTES AND REGULATIONS.  Antennas, wires and 
appliances of Tenant shall be erected and maintained in accord with the 
requirements and specifications of the safety codes of the State where the 
Premises are located or any applicable jurisdiction or any amendments or 
revisions thereof, and in compliance with any rules or orders now in effect, 
or that hereafter may be issued by the Federal Communications Commission.

     16.  AUTOMATIC TERMINATION.  Licensor may terminate this Agreement 
immediately and the parties shall deem Tenant to be in default if any of the 
following occurs:  (i) Tenant is declared bankrupt or files for bankruptcy 
protection; (ii) Tenant is adjudged insolvent, and such judgment is not 
reversed within thirty (30) days of entry; (iii) a receiver is appointed to 
manage Tenant and/or its assets, and such appointment is not overturned 
within thirty (30) days; or, (iv) Tenant is found by a court of competent 
jurisdiction to have engaged in felonious activity in the operation of 
equipment at the Premises. Termination by Licensor for the causes listed 
above shall not create a reduction, offset, or relief from liability of all 
charges due and owing Licensor which have accrued up to the time when 
termination is elected.

     17.  PASS THROUGHS.  In addition to the annual rental payments to be 
made by Tenant, Tenant agrees to pay its reasonable pro rata or 
representative portion of any increase in taxes, excluding income taxes; any 
road assessments levied for the provision of ingress and egress to the 
Premises; or increase in per unit rate of necessary utilities which occur 
following the commencement of the site License and which are billed to either 
party for operation of the Premises.  Charges for increased utility rates 
will not be passed through to tenants which are billed separately by the 
utility company for power and/or telephone service and Tenant agrees to 
separate metering of its electrical power at Tenant's sole expense.  Charges 
to Tenant for such increases may be commenced immediately following 
Licensor's receipt of a demand for higher costs from the applicable 
government agency, supplier, utility company or road maintenance company, 
without prior notification to or approval from tenant, however, Licensor 
shall provide to Tenant all documentation necessary to demonstrate the source 
and amount of any increase directly attributable to Tenant's equipment on the 
Premises.  Under no circumstances shall 

                                       13

<PAGE>

Licensor charge Tenant for such increases in a manner that might result in a 
profit to Licensor. Tenant's failure to pay any such charges upon demand by 
Licensor shall be deemed to be a failure to pay rents as required herein.

     18.  COMPLIANCE WITH LAW REGARDING AUTHORITY TO OPERATE.  Except as 
specifically provided herein, the parties shall be responsible for compliance 
with all laws, statutes and regulations for which their authority to operate 
radio equipment, or operate the Premises or Property as the case may be, is 
dependent.  No party shall indemnify the other or be made liable in any way 
for any other party's failure to act in compliance  with any rule or law, 
including violations which result in criminal prosecution or punitive action 
against a party, no matter what the source or cause of the violation of law 
might be except as provided for in Paragraph 6(D) above.  Accordingly, each 
party shall be solely responsible for its actions and its defense of such 
actions before any official agency or relevant court, with the sole 
responsibility party(ies) being those named in such action.

     19.  INTERFERENCE.  Tenant shall have full and complete responsibility 
to correct, within seventy-two (72) hours, any electrical interference caused 
to other communications equipment at the Property by operation of Tenant's 
equipment, which cause is a result of a defect in Tenant's equipment.  The 
term "defect" shall include any operating of Tenant's equipment which is not 
in accord with the technical parameters of any license issued by the Federal 
Communications Commission for operation of Tenant's facilities; any operation 
in variance with any equipment authorization granted by the Federal 
Communications Commission for operation of Tenant's facilities; any operation 
in variance with any equipment authorization granted by the Federal 
Communications Commission for sale, marketing and use of Tenant's equipment; 
any circumstance or condition which causes Tenant's equipment to operate in 
variance with any Exhibit attached to the subject Site License hereto; and 
any operation of tenant's equipment which does not conform with generally 
accepted practices of telecommunications engineering, including, but not 
limited to, applicable ANSI standards which exist or come to exist.  Licensor 
warrants that the terms contained within this Paragraph 19 are substantially 
similar to and reflected within all other licenses entered into by Licensor 
for third parties' occupation and use of all or part of the Property and 
shall be included in substantially similar form within future licenses 
entered into by Licensor for future tenants' use of all or part of the 
Property.

     (A)  Licensor hereby agrees to cooperate reasonably with Tenant in 
relieving any harmful electrical interference to Tenant's equipment caused by 
the operation of other telecommunications facilities on the Premises, 
including directing the interfering operator to discontinue the creation of 
such harmful interference 

                                       14

<PAGE>

or exercising Licensor's right to disconnect the operation of offending 
facilities until such time as the harmful interference can be resolved.  In 
the event that the parties' cooperation cannot relieve the receipt of harmful 
electrical interference to Tenant's equipment within thirty (30) days 
following Tenant's providing to Licensor notification of the existence of the 
harmful interference, and said interference is not caused by any defect or 
unreasonable condition in Tenant's equipment or operation, Tenant may 
terminate this License and/or seek any other remedies available to Tenant at 
law or in equity, including an injunction against the interfering party; 
providing, however, such termination or remedies shall be without liability 
to Licensor, except for acts or omissions of Licensor in violation of this 
Agreement.

     20.  SUITABILITY.  Tenant warrants that prior to the Commencement Date, 
it will examine the Premises to its satisfaction and that if Tenant does not 
send Licensor written notification to the contrary, Tenant's election not to 
notify Licensor otherwise shall be deemed to be Tenant's acceptance of the 
Premises as suitable for occupation by Tenant for the purposes described 
herein.  In the event that Tenant determines that the Premises are unsuitable 
for Tenant's occupation and use, Tenant may terminate the Site License for 
said Premises without further liability to either party.  Tenant further 
acknowledges that Licensor does not warrant, in any way, the quality, range, 
or propagation characteristics of any radio signal to be transmitted by 
operation of Tenant's equipment.

     21.  ENVIRONMENTAL LAWS.  Tenant represents, warrants and agrees that it 
will conduct its activities on the Premises in compliance with all applicable 
Environmental Laws.  Licensor represents, warrants and agrees that it has in 
the past and will in the future, conduct its activities on the Property in 
compliance with all applicable Environmental Laws and that the Property is 
free of hazardous substances as of the date of this License.

     Licensor shall be responsible for, and promptly cause to be performed, 
any investigation and remediation as required by any environmental laws or 
common law, of all spills or other release of hazardous substances, not 
caused solely by Tenant, that have occurred or which may occur on the 
Property.

     Tenant agrees to defend, indemnify and hold Licensor harmless from and 
against any and all claims, causes of action, demands, and liability 
including, but not limited to, damages, costs, expenses, assessments, 
penalties, fines, losses, judgments and attorney's fees that Licensor may 
suffer due to the existence or discovery of any hazardous substance on the 
Premises or the migration of any hazardous substance to other properties or 
release into the environment, arising solely from Tenant's activities on the 
Premises.

                                       15

     Licensor agrees to defend, indemnify and hold Tenant harmless from and 
against any and all claims, causes of action, demands and liability 
including, but not limited to, damages, costs, expenses, assessments, 
penalties, fines, losses, judgments and attorney's fees that Tenant may 
suffer due to the existence or discovery of any hazardous substance, except 
radio frequency emissions on the Property, or the migration of any hazardous 
substance to other properties or released into the environment, that relate 
to or arise from Licensor's activities during the term of this License (or 
the activities of third parties acting under the authority of Licensor) and 
from all conditions and activities on the Property prior to the commencement 
of this License.

     The indemnification in this Paragraph specifically includes costs 
incurred in connection with any investigation of site conditions or any 
cleanup, remedial, removal or restoration work required by any governmental 
authority.

     Notwithstanding the foregoing, Tenant agrees to cooperate with Licensor 
and other users of the Property to resolve any violations of RF emission 
standards created by the operation, collocation, and use of the Property by 
Tenant and all other users, which standards are promulgated by the FCC, 
including, if necessary, the provision of shielding devices or hardware or 
other such remedies which are reasonably required to assure compliance with 
all such regulations. Licensor agrees to cooperate with Tenant to assist in 
assuring compliance with all FCC promulgated RF exposure limitations, 
including providing to Tenant upon request, all relevant information which 
Licensor has in its possession regarding the equipment employed by collocated 
systems operating upon the Property.

     Each party warrants that they shall provide immediate notification to 
the other party of any investigation or lawsuit commenced by any agency, 
governmental body, person, or forum regarding any alleged violation of any 
environmental protection law.  A party's failure to provide such notification 
will not, however, be deemed a waiver of a party's obligation to provide 
indemnification required hereunder.

     This Paragraph 21 shall survive the expiration or earlier termination of 
this Agreement or the Site License.

     22.  CONDEMNATION.  In the event that the Premises or any portion 
thereof are taken pursuant to a condemnation proceeding or by eminent domain, 
such that Tenant can no longer operate its telecommunications equipment on 
the premises, the Site License shall terminate without liability to either 
party and Tenant shall not only be entitled to any portion of any award 
arising out of such proceedings which are attributable to any of Tenant's 

                                       16

Albert H. Pharis, Jr., an individual (the "Consultant"), dated as of the 21st
day of December, 1998 (the "Effective Date").

service mobile telecommunications including cellular telecommunications (the 
"Business"); and

     WHEREAS, pursuant to an Agreement and Plan of Merger dated as of July 
28, 1998, the Company, through an indirect subsidiary, has agreed to acquire 
Sygnet (the "Sygnet Acquisition"); and 

     WHEREAS, Consultant is a director and is President and Chief Executive 
Officer of Sygnet; and

     WHEREAS, Consultant, in his capacity as President and Chief Executive 
Officer of Sygnet, has been instrumental in developing the goodwill of the 
Business by virtue of his intimate knowledge of all aspects of the Business 
and his personal relationships with the employees and certain customers of 
the Business; and 

     WHEREAS, the Company desires to preserve and protect the value of the 
Business and goodwill to be acquired by the Company, and the value of any 
goodwill developed following the Company's acquisition of Sygnet as a result 
of Consultant's services rendered pursuant to this Agreement; and

     WHEREAS, the Consultant has agreed to assist the Company in the 
transition of ownership, and the operation, of the Business, to maintain the 
confidentiality of certain information concerning the Business, and to 
refrain from competing with the Company and Sygnet for a reasonable period of 
time; 

     NOW, THEREFORE, in consideration of the covenants and agreements herein 
contained, the parties agree as follows:

     1.   ENGAGEMENT.  The Company hereby engages the Consultant as a

of the Company or its subsidiaries or his duties and responsibilities under 
this Agreement.

regard, Consultant will (i) use his best efforts (which shall not require an

Company in maintaining good business relations with the principal suppliers 
to and customers of the Business, and (ii) not take any action that would 
detract from or impair the business relationship of those parties.  
Consultant agrees that he will be available for advice and counsel to the

may reasonably request.

     3.   INDEPENDENT CONTRACTOR.  During the term of this Agreement,

               5.2.   CONSULTING FEE.  Commencing on the first day next 
following the expiration of the Transition Period and for the remainder of

the Consultant of a felony.  Further, for purposes of this paragraph 6.2: 

                      (a)     No act, or failure to act, on the Consultant's 
part shall be deemed "willful" unless done, or omitted to be done, by the 
Consultant not in good faith and without reasonable belief that the 
Consultant's action or omission was in the best interest of the Company.

                      (b)     The Consultant shall not be deemed to have been 
terminated for Cause unless and until there shall have been delivered to the 
Consultant a copy of a resolution duly adopted by the affirmative vote of a 
majority of the entire membership of the Board of Directors of the Company 
(excluding the Consultant) at a meeting of the Board called and held for such 
purpose (after reasonable notice to the Consultant and an opportunity for the 
Consultant, together with the Consultant's counsel, to be heard before the 
Board), finding that in the good faith opinion of the Board the Consultant 
was guilty of conduct set forth in clauses (i), (ii) or (iii) above and 
specifying the particulars thereof in reasonable detail.  The determination 
of the Board shall be binding upon the Company and the Consultant.

               6.3.   VOLUNTARY TERMINATION.  The Consultant may voluntarily 
terminate this Agreement ("Voluntary Termination") at any time during the 
Consulting Period.  A Voluntary Termination is any termination of this 
Agreement by the Consultant during the Consulting Period other than 
termination due to death, Cause or Disability.

               6.4.   NOTICE OF TERMINATION.  Any termination by the Company 
for Cause or Disability or by the Consultant by reason of his death or 
Voluntary Termination shall be communicated a 

                                       -4-

<PAGE>

Notice of Termination to the other party hereto in accordance with the terms 
of this Agreement.  For purposes of this Agreement, a "Notice of Termination" 
means a written notice which (i) indicates the specific termination provision 
in this Agreement relied upon, (ii) sets forth in reasonable detail the facts 
and circumstances claimed to provide a basis for termination of the 
Consultant's engagement under the provisions so indicated, (iii) if 
applicable, a copy of the resolution of the Board required by paragraph 6.2  
hereof, and (iv) specifies a date of termination, which date shall be the 
last day of the month of such notice.

          7.   OBLIGATIONS OF THE COMPANY UPON TERMINATION.

               7.1.   DEATH OR DISABILITY.  If this Agreement is terminated 
by reason of the Consultant's death or Disability, it shall terminate without 
further obligations of the Consultant or his legal representative, as the 
case may be, or the Company; provided, however, (i) in the event of the death 
of the Consultant, the Company shall continue to pay the Consulting Fee 
during the Consulting Period to the legal representative of Consultant or 
Consultant's designee or (ii) in the event of the Disability of the 
Consultant, the Company shall continue to pay the Consulting Fee during the 
Consulting Period to the Consultant or his legal representative, as the case 
may be, and (iii) in either event, any approved sums due under paragraphs 5.3 
and 5.4 which have been accrued and have been expended by the Consultant and 
which have not been reimbursed by the Company shall be paid to the Consultant 
or his legal representative, as the case may be.  In either of such events, 
with the exception of the Consulting Fee the Company shall have no further 
obligations to Consultant, Consultant's designee or his legal representative 
under or pursuant to this Agreement.

               7.2.   CAUSE OR VOLUNTARY TERMINATION.  If this Agreement is 
terminated for Cause or by reason of a Voluntary Termination, the Company 
shall have no further obligations to the Consultant from and after the 
termination date and Consultant shall not be entitled to any severance 
payment.  If on the date of termination for cause, Consultant holds any 
unexercised options to purchase capital stock of the Company, such options 
shall be deemed surrendered and cancelled as of the date of termination, 
without exercise.

               7.3.   INVOLUNTARY TERMINATION.  If this Agreement is 
terminated by the Company without cause and not by reason of the Consultant's 
death or Disability, the Company shall be obligated to pay to Consultant an 
amount equal to two monthly installments of the Consulting Fee described in 
Section 5.2 hereof for the two calendar months next following the date of 
such termination. In addition, in the event of an Involuntary Termination by 
the Company, and if at the date of such termination 

                                       -5-

<PAGE>

the Consultant shall hold unexercised options to purchase capital stock of 
the Company, the Consultant shall be entitled to exercise any and all options 
to purchase stock which, in accordance with the terms of such options, could 
be exercised within 12 months next following the date of termination.  Any 
additional unexercised options then held by Consultant shall be deemed 
surrendered and canceled as of the date of termination, without exercise. 

          8.   FULL SETTLEMENT.  Except for termination of this Agreement by 
the Company for Cause or as provided for in paragraph 10, the Company's 
obligations to make the payments provided for in this Agreement and otherwise 
to perform its obligations hereunder shall not be affected by any set-off, 
counterclaim, recoupment, defense or other claim, right or action which the 
Company may have against the Consultant or others.  In no event shall the 
Consultant be obligated to seek employment or take any other action by way of 
mitigation of the amounts payable to the Consultant under any of the 
provisions of this Agreement.

          9.   INDEMNIFICATION.  During the Consulting Period, the Company 
shall indemnify the Consultant for his acts under this Agreement to the same 
extent and manner it provides indemnification for its officers and directors.

          10.  CERTAIN REDUCTIONS OF PAYMENTS BY THE COMPANY.  In the event 
that any payment made by the Company to the Consultant pursuant to the terms 
of this Agreement shall be determined by the Internal Revenue Service as 
nondeductible for federal income tax purposes by the Company, such amount 
shall be repaid by the Consultant to the Company within 45 days after 
notification by the Company. In the event at the end of said period, 
Consultant has not reimbursed the Company for such sum, the Company shall 
have the right of offset as against the Consulting Fee with respect to any 
payments then due and owing, together with interest at the applicable federal 
rates provided for in Section 7872(f)(2) of the Code.

          11.  DISCLOSURE OF INFORMATION.  Consultant agrees that during the 
term of this Agreement and for a period of three (3) years next following the 
termination hereof, Consultant will not, without the prior written consent of 
the Board of Directors of the Company, directly or indirectly, in any 
individual, corporate or representative capacity whatsoever, reveal, divulge, 
disclose or communicate to any person, firm, association, corporation or 
other entity in any manner whatsoever information of any kind, nature or 
description concerning any matters affecting or relating to the Business

Business, (iv) the Company's financial affairs as they relate to the 
Business, (v) the Company's or Sygnet's methods and manner of operating the 
Business or (vi) the Company's plans, trade secrets, or other data of any 
kind, nature or description whatsoever relating to the Business.  Without

confidential, material or important, the parties hereto stipulate that as 
between them, the same are important, material and confidential and 
materially affect Buyer's effective and successful conduct of the Business 
and its goodwill.

          12.  COVENANT NOT TO COMPETE.  Consultant agrees that during the 
term of this Agreement and for a period of three (3) years next following the 
termination hereof, without the prior written consent of the Board of

Business, or any portion thereof or the Buyer in connection with such 
customers, suppliers, businesses, and accounts in the Restricted States;

               12.2.  Knowingly hire, attempt to hire, contact or solicit 
with respect to hiring any present employee or future employee or consultant 
of the Business or any portion thereof, or of Sygnet or the Company; 
provided, that the foregoing prohibition shall not extend to (a) a former 
employee of Sygnet whose employment by Sygnet or the Company was not 
continued following consummation of the Merger, or (b) a former employee of 
Sygnet or the Company whose employment by Sygnet or the Company, as the case 
may be, ceased more than twelve (12) months prior to contact by Consultant;

               12.3.  Knowingly engage in, or give any advice to, any person, 
firm, partnership, association, corporation or other entity engaged in a 
business competitive with the Business or any 

                                       -7-

portion thereof in the Restricted States;

               12.4.  Lend credit, money or reputation for the purpose of 
establishing or operating a business competitive with the Business or any 
portion thereof in the Restricted States; or provided, however, that the 
foregoing provisions of this Section 12 shall not apply to the Consultant's 
investment in or employment by the communications tower business controlled 
by Gregory T. Pauley, nor employment by or the ownership of less than a 5% 
investment interest in a significantly active regional wireless provider who 
may be in competition with Sygnet, such as Western Wireless or Nextel, or a 
nationally active wireless provider who may be in competition with Sygnet, 
such as AT&T Wireless.

          These covenants are intended to restrict Consultant and his 
Affiliates, agents and representatives from competing in any manner with the 
Business, any portion thereof or Sygnet or the Company in the activities 
which have heretofore been carried on by Sygnet or the Company in connection 
with the Business or any portion thereof.  The parties hereto agree that 
prohibitions set forth in this Section 12 shall be liberally interpreted in 
order to carry out the intents and purposes of this Agreement.  As used in 
this Agreement, the term "Affiliate" shall mean a person that directly, or 
indirectly through one or more intermediaries, controls or is controlled by, 
or is under common control with, the person specified; and, when used to 
indicate a relationship with any person, shall include (i) a corporation or 
organization of which such person is an officer or partner or is, directly or 
indirectly, the beneficial owner of 10 percent or more of any class of equity 
securities, (ii) any trust or other estate in which such person has a 
substantial beneficial interest or as to which such person serves as trustee 
or in a similar capacity, and (iii) any relative or spouse of such person, or 
any relative of such spouse, who has the same home as such person or who is a 
director or officer of the person or any of its parents or subsidiaries.

          13.  ENFORCEMENT OF COVENANTS.  Consultant acknowledges that a 
violation or attempted violation on its part of any agreement in Sections 11 
or 12 above will cause such damage to the Company and the Business which will 
be irreparable, and accordingly, Consultant agrees that the Company shall be 
entitled as a matter of right to an injunction from any court of competent 
jurisdiction, restraining any further violation of such agreements by 
Consultant and his Affiliates, their respective employees, agents or 
representatives, either individually or collectively.  Consultant further 
agrees that the three (3) year period of restriction set forth in Sections 11 
and 12 above shall be tolled during any period of violation thereof by 
Consultant or any of his Affiliates.  Any exercise by the Company of its 
rights pursuant to this Section 13 shall be cumulative and in addition to any 
other 

                                       -8-

<PAGE>

remedies to which the Company may be entitled.

          14.  BOARD OF DIRECTORS.  Upon (a) execution of this Agreement by 
Consultant, and (b) consummation of the Sygnet Acquisition, it is intended 
that Consultant will be elected to the office of, and become a director of 
the Company.  Consultant agrees that so long as he is a member of the 
Company's Board of Directors, Consultant will attend all meetings of the 
Board of Directors and, on an annual basis, at least two (2) company strategy 
sessions, wherever held, unless Consultant is unable to attend by reason of 
illness, physical infirmity or family emergency.  Upon Consultant becoming a 
member of the Company's Board of Directors, the Company agrees that it will 
grant to Consultant options, under the Company's 1996 Stock Option Plan, as 
amended (the "Plan"), options to purchase an aggregate of 833 shares of the 
Company's Class B Common Stock at an option exercise price per share equal to 
the fair market value of the Company's Class B Common Stock as determined by 
a majority of the members of the Company's Board of Directors, subject to the 
terms of such Plan and the other provisions contained in this Agreement.

          15.  ASSIGNMENT, BINDING EFFECT AND SUCCESSORS.

               15.1.  ASSIGNMENT.  This Agreement is personal to the

    The undersigned acknowledges receipt of the Prospectus dated            ,
1997 (the "Prospectus") of Dobson/Sygnet Communications Company
("Dobson/Sygnet") which, together with this Letter of Transmittal (the "Letter
of Transmittal"), constitutes Dobson's offer (the "Exchange Offer") to exchange
$1,000 in principal amount of a new series of 12 1/4% Senior Notes Due 2008 (the
"New Notes") of Dobson for each $1,000 in principal amount of outstanding
12 1/4% Senior Notes Due 2008 (the "Old Notes") of Dobson. The terms of the New
Notes are identical in all material respects (including principal amount,
interest rate and maturity) to the terms of the Old Notes for which they may be
exchanged pursuant to the Exchange Offer, except that the New Notes will have
been registered under the Securities Act of 1933, as amended, and, therefore,
will not bear legends restricting the transfer thereof.
 
    The Exchange Offer is being made pursuant to the Registration Rights
Agreement dated as of December 23, 1998 (the "Registration Rights Agreement"),
and all Old Notes validly tendered will be accepted for exchange. Any Old Notes
not tendered will remain outstanding and continue to accrue interest, but will
not retain any rights under the Registration Rights Agreement. Holders electing
to have Old Notes exchanged pursuant to the Exchange Offer will be required to
surrender such Old Notes, together with the Letter of Transmittal, to the
Exchange Agent at the address specified herein prior to the close of business on
the Expiration Date. Holders will be entitled to withdraw their election, at any
time prior to 5:00 p.m., New York City time on the Expiration Date, by sending
to the Exchange Agent at the address specified herein a facsimile transmission
or letter setting forth the name of such Holder, the principal amount of Old
Notes delivered for exchange and a statement that such Holder is withdrawing
this election to have such Old Notes exchanged.

Letter of Transmittal to indicate the action the undersigned desires to take
with respect to the Exchange Offer.

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY
 
LADIES AND GENTLEMEN:
 
    Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to Dobson/ Sygnet the above-described principal
amount of Old Notes. Subject to, and effective upon, the acceptance for exchange
of the Old Notes tendered herewith, the undersigned hereby exchanges, assigns
and transfers to, or upon the order of, Dobson/Sygnet all right, title and
interest in and to such Old Notes. The undersigned hereby irrevocably
constitutes and appoints the Exchange Agent as the true and lawful agent and
attorney-in-fact of the undersigned (with full knowledge that said Exchange
Agent acts as the agent of the undersigned in connection with the Exchange
Offer) to cause the Old Notes to be assigned, transferred and exchanged. The
undersigned represents and warrants that it has full power and authority to
tender, exchange, assign and transfer the Old Notes and to acquire New Notes
issuable upon the exchange of such tendered Old Notes, and that, when the same
are accepted for exchange, Dobson/ Sygnet will acquire good and unencumbered
title to the tendered Old Notes, free and clear of all liens, restrictions,
charges and encumbrances and not subject to any adverse claim. The undersigned
also warrants that it will, upon request, execute and deliver any additional
documents deemed by Dobson to be necessary or desirable to complete the
exchange, assignment and transfer of tendered Old Notes or to transfer ownership
of such Old Notes on the account books maintained by The Depository Trust
Company.
 
    The Exchange Offer is subject to certain conditions as set forth in the
Prospectus under the caption "The Exchange Offer--Conditions of the Exchange
Offer." The undersigned recognizes that as a result of these conditions (which
may be waived, in whole or in part, by Dobson/Sygnet) as more particularly set
forth in the Prospectus, Dobson/Sygnet may not be required to exchange any of
the Old Notes tendered hereby and, in such event, the Old Notes not exchanged
will be returned to the undersigned at the address shown below the signature of
the undersigned.
 
    By tendering, each Holder of Old Notes represents to Dobson/Sygnet that (i)
the New Notes acquired pursuant to the Exchange Offer are being obtained in the
ordinary course of business of the person receiving such New Notes, whether or
not such person is such Holder, (ii) neither the Holder of Old Notes nor any
such other person has an arrangement or understanding with any person to
participate in the distribution of such New Notes, (iii) if the Holder is not a
broker-dealer or is a broker-dealer but will not receive New Notes for its own
account in exchange for Old Notes, neither the Holder nor any such other person
is engaged in or intends to participate in a distribution of the New Notes and
(iv) neither the Holder nor any such other person is an "affiliate" of
Dobson/Sygnet within the meaning of Rule 405 under the Securities Act of 1933,
as amended (the "Securities Act") or, if such Holder is an "affiliate," that
such Holder will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable. If the tendering
Holder is a bro-ker-dealer (whether or not it is also an "affiliate" of
Dobson/Sygnet within the meaning of Rule 405 under the Securities Act) that will
receive New Notes for its own account in exchange for Old Notes, it acknowledges
that it will deliver a prospectus meeting the requirements of the Securities Act
in connection with any resale of such New Notes. By acknowledging that it will
deliver and by delivering a prospectus meeting the requirements of the
Securities Act in connection with any resale of such New Notes, the undersigned
is not deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.
<PAGE>
    All authority herein conferred or agreed to be conferred shall survive the
death, bankruptcy or incapacity of the undersigned and every obligation of the
undersigned hereunder shall be binding upon the heirs, personal representatives,
executors, administrators, successors, assigns, trustees in bankruptcy and other
legal representatives of the undersigned. Tendered Old Notes may be withdrawn at
any time prior to 5:00 p.m., New York City Time on the Expiration Date.

and any Old Notes delivered herewith but not exchanged, in each case registered
in the name of the undersigned, shall be delivered to the undersigned at the

                       FORMING PART OF THE TERMS AND CONDITIONS
                                OF THE EXCHANGE OFFER
 
    1.  DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES.  Certificates
for all physically delivered Old Notes, as well as a properly completed and duly
executed copy of this Letter of Transmittal or facsimile thereof, and any other
documents required by this Letter of Transmittal, must be received by the
Exchange Agent at any of its addresses set forth herein on or prior to the
Expiration Date.
 
    THE METHOD OF DELIVERY OF OLD NOTES, THIS LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF
THE HOLDER AND, EXCEPT AS OTHERWISE PROVIDED BELOW, THE DELIVERY WILL BE DEEMED
MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. INSTEAD OF DELIVERY BY
MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE.
 
    Holders whose Old Notes are not immediately available or who cannot deliver
their Old Notes and all other required documents to the Exchange Agent on or
prior to the Expiration Date may tender their Old Notes pursuant to the
guaranteed delivery procedure set forth in the Prospectus under "The Exchange
Offer--Terms of the Exchange Offer--Guaranteed Delivery Procedures." Pursuant to
such procedure: (i) such tender must be made by or through an Eligible
Institution (as defined in the Prospectus); (ii) on or prior to the Expiration
Date, the Exchange Agent must have received from such Eligible Institution a
letter, telegram or facsimile transmission setting forth the name and address of
the tendering Holder, the name(s) in which such Old Notes are registered, and
the certificate number(s) of the Old Notes to be tendered; and (iii) all
tendered Old Notes as well as this Letter of Transmittal and all other documents
required by this Letter of Transmittal must be received by the Exchange Agent
within three New York Stock Exchange trading days after the date of execution of
such letter, telex, telegram or facsimile transmission, all as provided in the
Prospectus under the caption "The Exchange Offer--Terms of the Exchange
Offer--Guaranteed Delivery Procedures."
 
    No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering Holders, by execution of this Letter of Transmittal (or
facsimile thereof), shall waive any right to receive notice of the acceptance of
the Old Notes for exchange.
 
    2.  PARTIAL TENDERS; WITHDRAWALS.  Tenders of Old Notes will be accepted in
denominations of $1,000 and integral multiples in excess thereof. If less than
the entire principal amount of Old Notes evidenced by a submitted certificate is
tendered, the tendering Holder must fill in the principal amount tendered in the
column entitled "Principal Amount Tendered." A newly issued certificate for the
principal amount of Old Notes submitted but not tendered will be sent to such
Holder as soon as practicable after the Expiration Date. All Old Notes delivered
to the Exchange Agent will be deemed to have been tendered unless otherwise
indicated. To withdraw a tender of Old Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to 5:00 p.m., New York City time, on
the Expiration Date. Any such notice of withdrawal must (i) specify the name of
the person having deposited the Old Notes to be withdrawn (the "Depositor"),
(ii) identify the Old Notes to be withdrawn (including the certificate number or
numbers and principal amount of such Old Notes), (iii) contain a statement that
such holder is withdrawing its election to have such Old Notes exchanged, (iv)
be signed by the Holder in the same manner as the original signature on the
Letter of Transmittal by which such Old Notes were tendered (including any
required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the Old Notes register the
transfer of such Old Notes in the name of the person withdrawing the tender and
(v) specify the name in which any such Old Notes are to be registered, if
different from that of the Depositor. If Old Notes have been tendered pursuant
to the procedure for book-entry transfer, any notice of withdrawal must specify
the name and number of the account at the book-entry transfer facility. All
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by Dobson, whose determination shall be final
and binding on all parties. Any Old Notes so withdrawn will be deemed not to
have been validly tendered for purposes of the Exchange Offer and no New Notes
will be issued with respect thereto unless the Old Notes so withdrawn are
validly retendered. Any Old Notes which have been tendered but which are not
accepted for exchange will be returned to the Holder thereof without cost to
such Holder as soon as practicable after withdrawal, rejection of tender or
termination of the Exchange Offer. Properly withdrawn Old Notes may be
retendered by following one of the procedures described herein at any time prior
to the business day prior to the Expiration Date.
<PAGE>
    3.  SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND
ENDORSEMENTS; GUARANTEE OF SIGNATURES.  If this Letter of Transmittal is signed
by the registered Holder(s) of the Old Notes tendered hereby, the signature must
correspond with the name(s) as written on the face of certificates without
alteration, enlargement or any change whatsoever.
 
    If tendered Old Notes are registered in the name of the signer of the Letter
of Transmittal and the New Notes to be issued in exchange therefor are to be
issued (and any untendered Old Notes are to be reissued) in the name of the
registered holder (including any participant in The Depository Trust Company
(also referred to as a book-entry facility) whose name appears on a security
listing as the owner of Old Notes), the signature of such signer need not be
guaranteed. In any other case, the tendered Old Notes must be endorsed or
accompanied by written instruments of transfer in form satisfactory to
Dobson/Sygnet and duly executed by the registered holder and the signature on
the endorsement or instrument of transfer must be guaranteed by an eligible
guarantor institution which is a member of one of the following recognized
signature guarantee programs (an "Eligible Institution"): (i) The Securities
Transfer Agents Medallion Program (STAMP), (ii) The New York Stock Exchange
Medallion Signature Program (MSF), or (iii) The Stock Exchange Medallion Program
(SEMP).
 
    If the New Notes or Old Notes not exchanged are to be delivered to an
address other than that of the registered holder appearing on the note register
for the Old Notes, the signature in the Letter of Transmittal must be guaranteed
by an Eligible Institution.
 
    Endorsements on certificates or signatures on separate written instruments
of transfer or exchange required by this Instruction 3 must be guaranteed by an
Eligible Institution.
 
    If any of the Old Notes tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.
 
    If a number of Old Notes registered in different names are tendered, it will
be necessary to complete, sign and submit as many separate copies of this Letter
of Transmittal as there are different registrations of Old Notes.
 
    When this Letter of Transmittal is signed by the registered Holder or
Holders of Old Notes listed and tendered hereby, no endorsements of certificates
or separate written instruments of transfer or exchange are required.
 
    If this Letter of Transmittal is signed by a person other than the
registered Holder or Holders of the Old Notes listed, such Old Notes must be
endorsed or accompanied by separate written instruments of transfer or exchange
in form satisfactory to Dobson/Sygnet and duly executed by the registered Holder
or Holders, in either case signed exactly as the name or names of the registered
Holder or Holders appear(s) on the Old Notes.
 
    If this Letter of Transmittal, any certificates or separate written
instruments of transfer or exchange are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others
acting in a fiduciary or representative capacity, such persons should so
indicate when signing, and, unless waived by Dobson, proper evidence
satisfactory to Dobson/Sygnet of their authority so to act must be submitted.
 
    4.  TRANSFER TAXES.  Dobson/Sygnet shall pay all transfer taxes, if any,
applicable to the exchange of Old Notes pursuant to the Exchange Offer. If,
however, certificates representing New Notes, or Old Notes for principal amounts
not tendered or accepted for exchange, are to be delivered to, or are to be
issued in the name of, any person other than the registered Holder of the Old
Notes tendered hereby, or if a transfer tax is imposed for any reason other than
the exchange of Old Notes pursuant to the Exchange Offer, then the amount of any
such transfer taxes (whether imposed on the registered Holder or any other
person) will be payable by the tendering Holder. If satisfactory evidence of
payment of such taxes or exemption therefrom is not submitted herewith, the
amount of such transfer taxes will be billed directly to such tendering Holder.
 
    Except as provided in this Instruction 4, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes listed in this Letter of
Transmittal.
 
    5.  WAIVER OF CONDITIONS.  Dobson/Sygnet reserves the absolute right to
waive, in whole or in part, any of the conditions to the Exchange Offer set
forth in the Prospectus.
 
    6.  MUTILATED, LOST, STOLEN OR DESTROYED NOTES.  Any Holder whose Old Notes
have been mutilated, lost, stolen or destroyed should contact the Exchange Agent
at the address indicated above for further instructions.
 
    7.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions relating to the
procedure for tendering and other questions relating to the Exchange Offer, as
well as requests for assistance or additional copies of the Prospectus and this
Letter of Transmittal, may be directed to the Exchange Agent at the address and
telephone number set forth above and in the Prospectus.
<PAGE>
    8.  IRREGULARITIES.  All questions as to the validity, form, eligibility
(including time of receipt), and acceptance of Letters of Transmittal or Old
Notes will be resolved by Dobson/Sygnet, whose determination will be final and
binding. Dobson/Sygnet reserves the absolute right to reject any or all Letters
of Transmittal or tenders that are not in proper form or the acceptance of which
would, in the opinion of Dobson/Sygnet's counsel, be unlawful. Dobson/Sygnet
also reserves the right to waive any irregularities or conditions of tender as
to the particular Old Notes covered by any Letter of Transmittal or tendered
pursuant to such Letter of Transmittal. None of Dobson/Sygnet, the Exchange
Agent or any other person will be under any duty to give notification of any
defects or irregularities in tenders or incur any liability for failure to give
any such notification. Dobson/Sygnet's interpretation of the terms and
conditions of the Exchange Offer shall be final and binding.
 
    9.  DEFINITIONS.  Capitalized terms used in this Letter of Transmittal and
not otherwise defined have the meanings given in the Prospectus.
 
    10.  TAX IDENTIFICATION NUMBER.  Federal income tax law requires that a
holder of any Old Notes which are accepted for exchange must provide
Dobson/Sygnet (as payor) with its correct taxpayer identification number
("TIN"), which, in the case of a holder who is an individual, is his or her
social security number. If Dobson/Sygnet is not provided with the correct TIN,
the holder may be subject to a $50 penalty imposed by the Internal Revenue
Service. (If withholding results in an over-payment of taxes, a refund may be
obtained.) Certain holders (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements; however, these holders still must submit the Substitute
Form W-9. See the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional instructions.
 
    To prevent backup withholding, each tendering holder must provide such
holder's correct TIN by completing the Substitute Form W-9 set forth herein,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN), and that (i) the holder has not been notified by the Internal Revenue
Service that such holder is subject to backup withholding as a result of failure
to report all interest or dividends or (ii) the Internal Revenue Service has
notified the holder that such holder is no longer subject to backup withholding.
The Form must be signed, even if the holder is exempt from backup withholding.
If the Old Notes are registered in more than one name or are not in the name of
the actual owner, consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for information on which TIN to
report.
 
    Dobson/Sygnet reserves the right in its sole discretion to take whatever
steps are necessary to comply with its obligation regarding backup withholding.
 
    IMPORTANT: THIS LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF (TOGETHER WITH
CERTIFICATES FOR OLD NOTES AND ALL OTHER REQUIRED DOCUMENTS) OR A NOTICE OF
GUARANTEED DELIVERY MUST BE RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR TO THE
EXPIRATION DATE.

DIVIDENDS, OR PATRONAGE DIVIDENDS, ALSO SIGN AND DATE THE FORM.

who must report the payments to IRS. IRS uses the numbers for identification
purposes and to help verify the accuracy of the recipient's tax return. Payers
must be given the numbers whether or not recipients are required to file tax
returns. Payers must generally withhold 31% of taxable interest, dividend, and
certain other payments to a payee who does not furnish a taxpayer identification
number to a payer. Certain penalties may also apply.
 
PENALTIES
 
    (1)  PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you
fail to furnish your taxpayer identification number to a payer, you are subject
to a penalty of $50 for each such failure which is due to reasonable cause and
not to willful neglect.
 
    (2)  CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If
you make a false statement with no reasonable basis which results in no
imposition of backup withholding, you are subject to a penalty of $500.
 
    (3)  CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Falsifying certifications
or affirmations may subject you to criminal penalties including fines and/or
imprisonment.
 
    FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL
REVENUE SERVICE.

    Enclosed for your consideration are the Prospectus, dated          , 1999
(the "Prospectus") and the related Letter of Transmittal (which together with
the Prospectus constitute the "Exchange Offer") in connection with the offer by
Dobson/Sygnet Communications Company, an Oklahoma corporation (the "Company"),
to exchange its 12 1/4% Senior Notes due 2008 (the "New Notes") for any and all
of its outstanding 12 1/4% Senior Notes due 2008 (the "Old Notes"), upon the
terms and subject to the conditions set forth in the Exchange offer.
 
    We are the Registered Holder of Old Notes held for your account. An exchange
of the Old Notes can be made only by us as the Registered Holder and pursuant to
your instructions. The Letter of Transmittal is furnished to you for your
information only and cannot be used by you to exchange the Old Notes held by us
for your account. The Exchange Offer provides a procedure for holders to tender
by means of guaranteed delivery.
 
    We request information as to whether you wish us to exchange any or all of
the Old Notes held by us for your account upon the terms and subject to the
conditions of the Exchange Offer.
 
    Your attention is directed to the following:
 
        1. The New Notes will be exchanged for the Old Notes at the rate of
    $1,000 principal amount of New Notes for each $1,000 principal amount of Old
    Notes. The New Notes will bear interest (as do the Old Notes) at a rate
    equal to 12 1/4% per annum from their date of issuance. Interest on the New
    Notes is payable semi-annually on June 15 and December 15, commencing June
    15, 1999. Holders of Old Notes that are accepted for exchange will receive,
    in cash, accrued interest thereon to, but not including, the date of
    issuance of the New Notes. Such interest will be paid with the first
    interest payment on the New Notes. Interest on the Old Notes accepted for
    exchange will cease to accrue on the day prior to the issuance of the New
    Notes. The form and terms of the New Notes are the same in all material
    respects as the form and terms of the Old Notes (which they replace) except
    that the New Notes have been registered under the Securities Act of 1933, as
    amended (the "Securities Act").
 
        2. Based on the interpretation by the staff of the Securities and
    Exchange Commission (the "SEC"), New Notes issued pursuant to the Exchange
    Offer in exchange for Old Notes may be offered for resale, resold and
    otherwise transferred by holders thereof (other than any such holder which
    is an "affiliate" of the Company within the meaning of Rule 405 under the
    Securities Act or a "broker" or "dealer" registered under the Securities
    Exchange Act of 1934, as amended (the "Exchange Act")) without compliance
    with the registration and prospectus delivery provisions of the Securities
    Act provided that such New Notes are acquired in the ordinary course of such
    holders' business and such holders have no arrangement with any person to
    participate in the distribution of such New Notes.
