                               THE EXCHANGE OFFER
 
    We completed on December 23, 1998 the private offering of $50.0 million of
12 1/4% Senior Exchangeable Preferred Stock. We entered into a registration
rights agreement with the initial purchaser 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
Exchangeable Preferred Stock. You are entitled to exchange in the exchange offer
your outstanding shares of 12 1/4% Senior Exchangeable Preferred Stock for
registered shares of 12 1/4% Senior Preferred Stock with substantially identical
terms. If the Exchange Offer is not completed by June 21, 1999, then the
dividend rate on the 12 1/4% Senior Exchangeable Preferred Stock will be
increased to 12 3/4% per year. You should read the discussion under the heading
"Summary Description of the Preferred Stock" and "Description of the Preferred
Stock" for further information regarding the registered 12 1/4% Senior
Exchangeable Preferred Stock.
 
    We believe that the shares of 12 1/4% Senior Exchangeable Preferred Stock
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 shares of 12 1/4%
Senior Exchangeable Preferred Stock.
 
                                   WHO WE ARE
 
   
    We are a leading provider of rural and suburban cellular telephone services.
Since we began providing our cellular service in 1990 in Oklahoma and the Texas
Panhandle, we have rapidly expanded our cellular operations with an acquisition
strategy targeting rural and suburban areas which have a significant number of
potential customers with substantial needs for cellular communications. At
December 31, 1998, our cellular systems covered a population of 5.7 million in
Arizona, California, Kansas, Maryland, Missouri, Ohio, Oklahoma, New York,
Pennsylvania and Texas. The Federal Communications Commission has divided the
United States into rural service areas ("RSAs") and metropolitan service areas
("MSAs"), and has issued separate licenses to conduct cellular telephone
operations in each RSA and MSA.
    
 
   
    We believe that our mix of rural and suburban cellular systems generally
provides strong growth opportunities due to lower penetration rates, higher
subscriber growth rates and a higher proportion of roaming revenue compared to
cellular systems located in larger MSAs. We focus on systems that are adjacent
to major metropolitan areas and include a high concentration of expressway
corridors that tend to have a significant amount of roaming activity in which
customers of a cellular provider in a distant area use the cellular system of
the provider in the current area while the customer is located in or roaming in
the current area.
    
 
   
    The following table sets forth certain data as of December 31, 1998 with
respect to our existing cellular markets. We determine market penetration by
dividing our total subscribers by the total population covered by the applicable
cellular license or authorizations that either we or our subsidiaries hold. In
September 1998, we closed into escrow our acquisition of the FCC license for,
and certain assets related to, Ohio 2 RSA for $39.3 million. In December 1998,
we closed into escrow our acquisition of the FCC license
    
 
                                       1
<PAGE>
   
for, and certain assets related to Texas 10 RSA. On March 16, 1999 we purchased
13,611 subscribers in Ohio 2 RSA from the previous operator, which we have not
included in the following table. The previous operator of Texas 10 RSA estimates
the number of subscribers in that market at 1,400, which we have not included in
the following table. We are negotiating for the purchase of subscribers in Texas
10 RSA. We recently entered into an agreement for the purchase of the FCC
licenses for, and certain assets related to, Maryland 1 RSA for $9.1 million,
subject to adjustment. Maryland 1 covers a population of 29,800 and the present
operator has 400 subscribers. For a description of the markets, see
"Business--Markets and Systems."

BUSINESS STRATEGY
 
    Our business strategy is to focus on the development and acquisition of
rural and suburban cellular systems. The principal elements of our strategy
include:
 
    - integrating the operations of systems we acquire with our existing
      cellular operations to achieve economies of scale.
 
   
    - continuing to maintain and expand strategic relationships with operators
      of cellular systems in major MSAs near our systems, including roaming
      agreements which allow our subscribers to use the system in the
      neighboring MSAs and RSAs at favorable rates.
    
 
   
    - distinguishing ourself as the local market's leading cellular services
      provider, stressing our service quality, local sales offices and
      commitment to the community.
    
 
                                       2

    - attracting subscribers who are likely to generate high monthly revenue and
      low churn rates.
 
    - maintaining high levels of customer satisfaction through a variety of
      techniques, including maintaining 24-hour customer service.
 
    - increasing capacity and upgrading our systems to attract additional
      subscribers, enhancing the use of our systems by existing subscribers,
      increasing roaming activity and further enhancing the overall efficiency
      of the network.
 
    - continually evaluating opportunities to acquire additional rural and
      suburban cellular systems.
 
OPERATIONS EXPECTED TO BE DISCONTINUED
 
    Through our wholly owned subsidiary, Logix Communications Enterprises, Inc.
("Logix,"), we provide integrated local, long distance, data and other
telecommunications services, and long-haul fiber optic facilities to business
customers throughout the Southwest United States.
 
   
    We have designated Logix an unrestricted subsidiary with the result that
Logix is not subject to certain covenant and similar restrictions which apply to
the rest of our operations. We intend to distribute the stock of Logix to
certain of our shareholders, subject to receipt of a favorable tax ruling from
the Internal Revenue Service or a favorable tax opinion acceptable to us and our
shareholders and to the receipt of consents from a majority of the principal
amount of our outstanding 11 3/4% Senior Notes due 2007. Holders of our
Preferred Stock will not participate in our distribution of Logix stock. Logix
is accounted for as a discontinued operation in our consolidated financial
statements.
    
 
   
RECENT EVENTS
    
 
   
    On December 23, 1998, our subsidiary, Dobson/Sygnet Communications Company,
acquired Sygnet for $337.5 million in cash.
    
 
   
    Effective January 16, 1999, we amended our operating agreement with AT&T
Wireless to modify the roaming airtime rates we will charge each other through
June 30, 2004. We believe the new rates will increase the total airtime used by
our customers which will increase our gross revenues.
    
 
   
    Effective April 13, 1999, AT&T Wireless entered into an agreement to
purchase certain shares of our Class D Preferred Stock and common stock from one
of our existing shareholders for $20 million. AT&T Wireless' purchase is subject
to compliance with the Hart-Scott-Rodino Act and other customary closing
conditions. Following the consummation of its stock purchase, AT&T Wireless will
have the right to appoint one member of our Board of Directors and to jointly
appoint an additional Board member.
    
 
   
    Our first quarter total operating revenues were approximately $68 million.
Our first quarter results do not include any operating revenue from the Ohio 2
RSA and Texas 10 RSA. Our subscriber count at March 31, 1999 was approximately
381,000, including 13,611 subscribers in Ohio 2 RSA that we purchased late in
the first quarter. This is an increase from 352,000 subscribers at December 31,
1998. Net subscriber additions for the quarter, not including subscribers
purchased in Ohio 2 RSA, were approximately 16,000.
    
 
   
    On May 5, 1999, we expect to conclude a private offering of $170 million of
another class of our preferred stock. We will use the net proceeds of that
offering to redeem all outstanding shares of our Class F Preferred Stock and
Class G Preferred Stock, to reduce our bank debt and for general corporate
purposes.

                   SUMMARY OF THE TERMS OF THE EXCHANGE OFFER
    
 
   
    In the exchange we are offering to exchange up to 67,146 outstanding shares
of our 12 1/4% Senior Exchangeable Preferred Stock including 64,646 shares
initially issued on December 23, 1998 together with additional shares issued in
the payment of dividends thereon (the "old shares"), for an equal number of
shares of our 12 1/4% Senior Exchangeable Preferred Stock ("new shares," and,
together with old shares the "Preferred Stock"). The form and terms of the new
shares are identical in all material respects to the form and terms of the
outstanding old shares except that the new shares 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 old shares.

Registration rights agreement.....  You are entitled to exchange your old shares for
                                    registered new shares 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 Preferred Stock.
The exchange offer................  We are offering to exchange one new share for each old
                                    share. We will accept for exchange all outstanding old
                                    shares that are validly tendered and not validly
                                    withdrawn. In order to be accepted, an outstanding old
                                    share must be properly tendered and accepted. After
                                    consummation of the exchange offer, holders of old
                                    shares which are not exchanged will continue to be
                                    subject to the existing restrictions upon the transfer
                                    of old shares and we will have no further obligation to
                                    such holders to provide for the registration of the old
                                    shares under the Securities Act.
Shelf registration................  We may be required to file a shelf registration
                                    statement with respect to our outstanding old shares if:
                                        - the Securities and Exchange Commission issues an
                                          interpretation that we are not permitted to effect
                                          the exchange offer,
                                        - we do not conclude the exchange offer by June 23,
                                          1999,
                                        - an initial purchaser of the old shares requests
                                        that we file a shelf registration statement with
                                          respect to notes held by the initial purchaser,
                                        - a holder of old notes
                                            (a) is not eligible to participate in the
                                            exchange offer, or
                                            (b) has participated in the exchange offer but
                                            does not receive freely tradeable new shares,
                                        - the initial purchaser has received new shares in
                                        the exchange offer or has otherwise been issued new
                                          shares in exchange for old shares constituting a
                                          portion of an unsold allotment, which new shares
                                          are not freely tradeable.
Resale of new shares..............  Based on interpretations by the staff of the Securities
                                    and Exchange Commission set forth in no-action letters
                                    issued to third parties, including "Exxon Holdings
                                    Corporation" (available May 13, 1998) and "Morgan
                                    Stanley & Co. Incorporated" (available June 5, 1991), we
                                    believe that you may offer the new shares for resale,
                                    resell the new shares and otherwise transfer the new
                                    shares without compliance with the registration and

                                    provided that:
                                        - you acquire the new shares in the exchange offer
                                        in the ordinary course of business;
                                        - you have no arrangement or understanding with any
                                          person to participate in the distribution of the
                                          new shares that you obtain in the exchange offer;
                                        - you are not a broker-dealer who purchased such
                                          outstanding Preferred Stock directly from us for
                                          resale pursuant to Rule 144A or any other
                                          available exemption under the Securities Act; and
                                        - you are not an "affiliate".
                                    We intend to rely on the existing no-action letters and
                                    we do not intend to seek a no-action letter from the
                                    Securities and Exchange Commission with respect to the
                                    resale of the new shares.
The 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 dividends on the new
  shares and the outstanding old
  shares..........................  Dividends on the new shares will accrue from January 15,
                                    1999. If we accept your old shares you will not receive
                                    any payment in respect of dividends on such outstanding
                                    old shares accrued from January 15, 1999 to the date of
                                    the issuance of the new shares. Consequently, holders
                                    who exchange their outstanding old shares for new shares
                                    will receive the same dividend payment on April 15,
                                    1999, which is the first dividend payment date with
                                    respect to the outstanding old shares and the new shares
                                    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 at any time prior to
                                    the expiration date 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 Securities and Exchange Commission
                                    of any existing law, statute, rule or regulation. We do
                                    not expect any of the foregoing conditions to occur,
                                    although there can be no assurance that such conditions
                                    will not occur. Holders of outstanding old shares will
                                    have certain rights against under the registration
                                    rights agreement executed as part of the offering of the
                                    outstanding old shares should we fail to consummate the
                                    exchange offer.
Conditions to the exchange
  offer...........................  The exchange offer is subject to certain conditions,
                                    which may be waived by us. See "The Exchange
                                    Offer--Conditions of the exchange offer." The exchange
                                    offer is not conditioned upon any minimum number of old
                                    shares being tendered.
Special procedures for beneficial
  owners..........................  If you are the beneficial owner of old shares and your
                                    name does not appear on a security position listing of

                                    take considerable time.

                                    outstanding old shares which are properly tendered in

<TABLE>
<S>                                 <C>
Securities offered................  Shares of our 12 1/4% Senior Exchangeable Preferred
                                    Stock.
 
Dividends.........................  Dividends on the Preferred Stock are payable in cash or,
                                    on or before January 15, 2003, at our option, in
                                    additional shares of Preferred Stock, on each January
                                    15, April 15, July 15 and October 15, beginning April
                                    15, 1999. For federal income tax purposes, we do not
                                    expect these distributions with respect to the Preferred
                                    Stock to qualify as dividends. Instead, we expect these
                                    distributions to be treated as a return of capital until
                                    we have earnings and profits as determined under
                                    applicable federal income tax principles. See "Federal
                                    Income Tax Considerations to U.S. Holders--Purchase,
                                    Ownership and Disposition of the Preferred
                                    Stock--Distributions on the Preferred Stock."
 
Liquidation preference............  $1,000 per share, plus accrued dividends.
 
Voting............................  Holders of the Preferred Stock will have no voting
                                    rights except as provided by law and as provided in the
                                    certificate of designation for the Preferred Stock. If
                                    we fail to pay dividends for any four quarters, whether
                                    or not consecutive, or upon certain other events
                                    including our failure to comply with covenants and to
                                    pay the mandatory redemption price when due, then the
                                    number of directors that make up our Board of Directors
                                    will be increased to permit the holders of the majority
                                    of the then outstanding shares of Preferred Stock,
                                    voting separately as a class, to elect two directors.
 
Mandatory redemption..............  We must redeem the Preferred Stock on January 15, 2008
                                    (subject to the legal availability of funds) at a
                                    redemption price equal to the liquidation preference,
                                    plus accrued dividends to the redemption date.
 
Optional redemption...............  We may redeem any of the Preferred Stock beginning
                                    January 15, 2003 at the redemption prices set forth in
                                    this Prospectus.
 
Public equity offering optional
  redemption......................  Before January 15, 2001, we may redeem up to 35% of the
                                    aggregate liquidation preference amount of the Preferred
                                    Stock at a redemption price equal to 112.250% of its
                                    liquidation preference amount, plus unpaid dividends,
                                    with net proceeds from a public offering of our common
                                    stock if at least 65% of the aggregate liquidation
                                    preference amount of Preferred Stock originally issued
                                    remains outstanding.
 
Ranking...........................  The Preferred Stock ranks:
 
                                        - equally with our Senior Preferred Stock;
 
                                        - senior to all other classes of our outstanding
                                        preferred stock and to all of our other capital
                                          stock;
 
                                        - equally with any capital stock we may issue in the
                                        future the terms of which expressly provide that it
                                          will rank equally with the Preferred Stock; and
 
                                        - junior to all of our capital stock we may issue in
                                        the future

                                          the terms of which expressly provide that such
                                          stock will rank senior to the Preferred Stock. As
                                          of the date of this prospectus, all of our
                                          outstanding of our capital stock, other than
                                          Senior Preferred Stock, would rank junior to the
                                          Preferred Stock. At December 31, 1998, we had
                                          $241.3 million liquidation preference of Senior
                                          Preferred Stock outstanding.
 
Optional exchange feature.........  We may exchange the Preferred Stock in whole but not in
                                    part into exchange debentures if the conditions
                                    described in the certificate of designation for the
                                    Preferred Stock are satisfied.
 
Certain covenants.................  The certificate of designation for the Preferred Stock
                                    contains certain covenants that restrict our ability and
                                    the ability of certain of our subsidiaries to:
 
                                        - incur additional indebtedness and issue certain
                                        capital stock,
 
                                        - create liens,
 
                                        - pay dividends on or make distributions in respect
                                        of capital stock,
 
                                        - redeem or repurchase our capital stock,
 
                                        - make investments or certain other restricted
                                          payments,
 
                                        - sell assets,
 
                                        - create restrictions on the ability of our
                                        restricted subsidiaries to make certain payments,
 
                                        - issue or sell stock of restricted subsidiaries,
 
                                        - enter into transactions with our stockholders or
                                          affiliates,
 
                                        - incur senior subordinated indebtedness, or
 
                                        - effect a consolidation or merger.
 
                                    However, these covenants are subject to a number of
                                    important qualifications and exceptions, which are
                                    described elsewhere in this prospectus under the heading
                                    "Description of the Preferred Stock--Covenants."
 
                                    We have designated our subsidiaries, Logix,
                                    Dobson/Sygnet and Sygnet and each of their subsidiaries
                                    as unrestricted subsidiaries. As a result, Logix,
                                    Dobson/Sygnet and Sygnet and each of their subsidiaries
                                    are not subject to the covenants contained in the
                                    certificate of designation governing the Preferred
                                    Stock.
 
Change of control.................  Upon change of control events, we must make an offer to
                                    purchase the Preferred Stock at a purchase price equal
                                    to 101% of the liquidation preference of the Preferred
                                    Stock, plus unpaid dividends. See "Description of the
                                    Preferred Stock."

                                    under "Description of the Exchange Debentures".
 
Maturity..........................  January 15, 2008.
 
Interest payment dates............  January 15 and July 15 of each year, beginning with the
                                    first of such dates to occur after the exchange date.
                                    Before January 15, 2003, we may pay interest on the
                                    Exchange Debentures by issuing additional Exchange
                                    Debentures.
 
Optional redemption...............  We may redeem any of the Exchange Debentures beginning
                                    January 15, 2003 at the redemption prices set forth in
                                    this Prospectus.
 
                                    Before January 15, 2001, we may redeem Exchange
                                    Debentures having an aggregate principal amount of up to
                                    35% of the principal amount of all Exchange Debentures
                                    we may have issued, at a redemption price equal to
                                    112.250% of the principal amount of the Exchange
                                    Debentures being redeemed, plus accrued and unpaid
                                    interest, with the proceeds of one or more sales of our
                                    common stock. We may make such redemption only if such
                                    redemption occurs within 180 days after completion of
                                    such sale and after any such redemption at least 65% of
                                    the aggregate principal amount of Exchange Debentures
                                    originally issued remains outstanding.
 
                                    Any optional redemption of Exchange Debentures must be
                                    pro rata with the optional redemption of our outstanding
                                    Senior Exchange Debentures that we may issue with
                                    respect to our Senior Preferred Stock.
 
Ranking...........................  Our Exchange Debentures will be senior subordinated
                                    indebtedness, ranking junior to all of our existing and
                                    future Senior Indebtedness as that term is defined under
                                    "Description of the Exchange Debentures", and senior to
                                    all of our subordinated indebtedness. Our Exchange
                                    Debentures will rank equally with any Senior Exchange
                                    Debentures that may be issued. At December 31, 1998, we
                                    had $1,121.6 million of consolidated indebtedness
                                    outstanding, and our subsidiaries had $961.6 million of
                                    indebtedness outstanding, all of which would have been
                                    effectively senior to the Exchange Debentures.
 
Certain covenants.................  The indenture under which our Exchange Debentures would
                                    be issued will contain certain covenants that restrict

                 SUMMARY PRO FORMA CONSOLIDATED FINANCIAL DATA
    
 
   
    The following summary unaudited pro forma consolidated financial data were
derived from the pro forma condensed consolidated financial data included
elsewhere in this prospectus. The pro forma statement of operations data for the
year ended December 31, 1998 give effect to the consummation of our acquisitions
of California 4 and Sygnet and the related financing, as if they occurred on
January 1, 1998. The summary unaudited pro forma consolidated financial data are
based on currently available information and certain assumptions that we believe
are reasonable. The pro forma financial information does not purport to
represent what our results of operations would have been if these transactions
had been completed on the dates indicated, nor does it purport to indicate our
future financial position or results of our future operations. You should read
the pro forma consolidated financial data in conjunction with "Selected
Consolidated Financial and Other Data," "Pro Forma Condensed Consolidated
Financial Data," "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the financial statements and related notes that
we include elsewhere in this prospectus.
    
 
   
    On a pro forma basis, our earnings would have been insufficient to cover
combined fixed charges and preferred stock dividends by $179.6 million for the
year ended December 31, 1998. We define "earnings" as earnings before
extraordinary items and accounting changes, interest expense, amortization of
deferred financing costs, taxes and a 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.
    
 
    The average monthly revenue per cellular subscriber excludes roaming revenue
and equipment revenue.

                 SUMMARY HISTORICAL CONSOLIDATED FINANCIAL DATA
    
 
   
    The following table set forth certain of our historical financial data. Our
summary historical financial data as of and for each of the three years ended
December 31, 1998 were derived from our audited consolidated financial
statements. You should read the historical consolidated financial data in
conjunction with "Selected Consolidated Financial and Other Data," "Pro Forma
Condensed Consolidated Financial Data," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and our financial statements, and
the related notes that we include elsewhere in this prospectus.
    
 
   
    Our earnings were insufficient to cover combined fixed charges and preferred
stock dividends by $2.3 million for the year ended December 31, 1996, by $21.6
million for the year ended December 31, 1997 and by $85.8 million for the year
ended December 31, 1998. We define "earnings" as earnings before extraordinary
items and accounting changes, interest expense, amortization of deferred
financing costs, taxes and a 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.
    
 
    We determine cellular penetration by dividing our total ending cellular
subscribers for the period by the estimated total population covered by
applicable FCC cellular licenses or authorizations that we hold.
 
    The average monthly revenue per cellular subscriber excludes roaming revenue
and equipment revenue.

                                  RISK FACTORS
    
 
    IN ADDITION TO THE INFORMATION CONTAINED IN THIS PROSPECTUS, YOU SHOULD
CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS IN EVALUATING WHETHER OR NOT YOU
SHOULD PARTICIPATE IN THE EXCHANGE OFFER. CERTAIN CAPITALIZED TERMS ARE DEFINED
IN "CERTAIN TERMS."
 
   
WE HAVE A SIGNIFICANT AMOUNT OF INDEBTEDNESS WHICH MAY LIMIT OUR ABILITY TO MEET
  OUR DEBT SERVICE AND DIVIDEND OBLIGATIONS, TO BORROW ADDITIONAL MONEYS AND TO
  SURVIVE A DOWNTURN IN OUR BUSINESS.
    
 
    At December 31, 1998, we had approximately $1,121.6 million of consolidated
indebtedness, all of which would rank senior to the Preferred Stock, $381.3
million aggregate liquidation preference of Senior Preferred Stock, a deficit in
consolidated stockholders' equity of $(156.8) million and $140.0 million of
availability under our credit facilities. The terms of the Preferred Stock also
allow us to incur additional indebtedness in the future. At December 31, 1998,
assuming that our acquisitions of California 4 and Sygnet, and the related
financing were completed at that time, our earnings would have been insufficient
to cover our fixed charges and preferred stock dividends by $179.6 million. See
"Description of the Preferred Stock," "Description of the Exchange Debentures,"
"Description of Certain Indebtedness" and "Description of Capital Stock."
 
   
    We have designated our subsidiaries, Logix, Dobson Tower Company,
Dobson/Sygnet and each of their subsidiaries as unrestricted subsidiaries and
they will not be subject to the covenants contained in the certificate of
designation that governs the Preferred Stock. There will be no limit under the
certificate of designation on the amount of debt that Logix, Dobson Tower
Company, Dobson/Sygnet and each of their subsidiaries will be able to incur, or
on their ability to create liens.
    
 
    Our level of indebtedness could have important consequences, including:
 
    - the debt service requirements could make it more difficult for us to pay
      cash dividends on the Preferred Stock or pay cash interest on the Exchange
      Debentures, if issued;
 
    - our ability to borrow additional money for working capital, capital
      expenditures, debt service or dividend payment requirements or other
      purposes is limited;
 
    - a substantial portion of our future cash flow from operations, if any,
      will be required to pay principal and interest payments on our
      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.
 
   
WE EXPECT TO REQUIRE SUBSTANTIAL AMOUNTS OF CAPITAL IN THE FUTURE.
    
 
   
    We have required, and will likely continue to require, substantial capital
to further develop and expand our cellular systems. We have budgeted $45 to $50
million for capital expenditures in 1999, approximately $32 million of which is
for the purchase of cell site and switching equipment. These amounts include
expenditures related to the Texas 10, Ohio 2 and Maryland 1 systems that we will
acquire. We have not budgeted any amounts to be expended in 1999 with respect to
the buildout of our PCS systems. We may require additional financing for future
acquisitions and for buildout requirements related to our PCS licenses.
    
 
    Sources of additional capital for us may include public and private equity
and debt financings, including vendor financing. The extent of additional
financing that we will require will depend on the success of our operations. We
may not be able to obtain any additional financing on terms acceptable to us
 
                                       16
<PAGE>
and within the limitations contained in the certificate of designation for the
Preferred Stock and the Senior Preferred Stock, the indenture relating to our
11 3/4% Senior Notes due 2007, the certificates of designation for each of our
other series of preferred stock, the terms of our credit facilities, our other
indebtedness or any future financing arrangements. See "Description of the
Preferred Stock," "Description of the Exchange Debentures," "Description of
Certain Indebtedness" and "Description of Capital Stock."
 
   
WE MAY BE UNABLE TO MEET OUR DEBT SERVICE REQUIREMENTS AND DIVIDEND OBLIGATIONS.
    
 
   
    We have experienced and will experience a substantial increase in total
indebtedness and in debt service and dividend requirements, and we and our
subsidiaries are, and will continue to be, subject to significant financial
restrictions and limitations. To be able to meet debt service and dividend
requirements, including obligations under our 11 3/4% Senior Notes due 2007, the
Senior Preferred Stock, the Preferred Stock, the Dobson/Sygnet 12 1/4% Senior
Notes due 2008 and our credit facilities, we must successfully implement our
business strategy of increasing market penetration, integrating the operations
of acquired systems 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 sufficient cash flow from operating activities to meet debt
service and dividend obligations, as well as other cash requirements, including
for working capital and capital expenditures.
    
 
   
    If we are unable to satisfy any of the covenants under our credit
facilities, including financial covenants, we will be unable to borrow under
these facilities during that time. Our inability to access such financing could
result in the delay or abandonment of some or all of our plans, which could
limit our ability to meet debt service and dividend obligations 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 instruments governing certain of our indebtedness, including our
credit facilities, contain provisions making it an event of default if we or
certain of our subsidiaries fail to pay or perform certain obligations under
other indebtedness. See "--Restrictions imposed in our governing instruments may
adversely affect our operations." Our ability to borrow under our credit
facilities will be limited by the requirement that, on a quarterly basis
beginning June 30, 2000, the amount available under our credit facilities will
reduce until the facilities terminate in June 2006, and beginning December 2000,
the amount available under Dobson/Sygnet's credit facilities will reduce until
the facilities terminate in December 2007. The reduction in availability may
require us to make significant principal payments thereunder. See "Description
of Certain Indebtedness."
    
 
   
WE WILL NEED TO REFINANCE OUR INDEBTEDNESS AT MATURITY OR WE WILL NEED TO SELL
  ASSETS TO MEET OUR FINANCIAL OBLIGATIONS.
    
 
   
    We will need to refinance our indebtedness under our credit facilities,
11 3/4% Senior Notes due 2007 and Dobson/Sygnet's 12 1/4% Senior Notes due 2008
at their respective maturities. We will also need to refinance our mandatory
redemption obligations under the Preferred Stock, the Senior Preferred Stock and
our other preferred stock. In addition, in the event implementation of our
strategy to develop and expand our systems is delayed or we do not generate
sufficient cash flow to meet our debt service requirements or obligations with
respect to our preferred stock, we may need to seek additional financing. Our
ability and that of our subsidiaries to do so will depend on, among other
things, our financial condition at the time, the restrictions in the instruments
governing our indebtedness and other factors, including market conditions,
beyond our control.
    
 
   
    Two of our credit facilities mature in 2006 and the Dobson/Sygnet credit
facilities mature in 2007. These credit facilities require substantial mandatory
prepayments prior to such dates. Our outstanding 11 3/4% Senior Notes due 2007
($160.0 million principal amount) mature April 15, 2007; and the Dobson/ Sygnet
12 1/4% Senior Notes due 2008 ($200.0 million principal amount) mature December
15, 2008. We must redeem the Senior Preferred Stock and the Preferred Stock on
January 15, 2008 at a redemption price of 100% of their liquidation preference
plus unpaid dividends. See "--We may be unable to pay cash dividends on the
Preferred Stock or interest on the Exchange Debentures." We must redeem
outstanding
    
 
                                       17
<PAGE>
shares of our Class D Preferred Stock and Class E Preferred Stock at a
redemption price of 100% of their liquidation preference (an aggregate of $85.0
million) plus accrued and unpaid dividends upon vote of the holders of a
majority of the outstanding shares of each class, after December 31, 2013, or
upon our completion of an initial public offering of our common stock. We must
redeem outstanding shares of our Class F Preferred Stock at a redemption price
of 130% of the liquidation preference plus unpaid dividends at December 31,
2013. We must redeem outstanding shares of our Class G Preferred Stock and Class
H Preferred Stock at a redemption price of 100% of their liquidation preference
(an aggregate of $25.0 million) plus unpaid dividends, upon the vote of the
holders of a majority of the outstanding shares of each class, after December
31, 2013, or upon our completion of an initial public offering of our common
stock.
 
    The following table reflects our mandatory redemption obligations with
respect to our outstanding shares of preferred stock of all classes, assuming
that:
 
    - no shares are redeemed or converted prior to the mandatory redemption
      date,
 
    - we are required to redeem at the earliest time provided for mandatory
      redemption, and
 
    - all dividends payable in kind are so paid:

(2) We have not issued any shares of our Class H Preferred Stock. We expect to
    redeem all of our Class F and Class G Preferred Stock with the proceeds of
    our private offering of $170 million of another class of preferred stock.
    Following such redemption, we expect to retire all of our Class F, Class G
    and Class H Preferred Stock.
    
 
    See "Description of the Preferred Stock," "Description of the Exchange
Debentures," and "Description of Capital Stock."
 
    Our failure to refinance any of our indebtedness or our preferred stock
redemption obligations may cause a default thereunder and under other of our
obligations and those of our subsidiaries. If we cannot obtain such financing or
refinancing, we could be forced to dispose of assets in order to make up for any
shortfall. At December 31, 1998, approximately 80.4% of our total assets
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 cellular business and the wireless telecommunications
industry in general. In addition, transfers of interests in such licenses are
subject to FCC approval. As a result, we cannot assure you that our assets could
be sold quickly enough, or for sufficient amounts, to enable us to meet our
obligations, including our obligations with respect to the Senior Preferred
Stock and Preferred Stock.
 
THE PREFERRED STOCK AND EXCHANGE DEBENTURES RANK JUNIOR IN RIGHT OF PAYMENT TO
  ALL OUR INDEBTEDNESS
 
    The Preferred Stock ranks junior to all of our present and future
indebtedness and other liabilities, equally with the Senior Preferred Stock, and
senior to all classes of our common stock and all classes of our other preferred
stock. In the event of our bankruptcy, liquidation or reorganization, our assets
will be available to pay obligations on the Preferred Stock only after all of
our outstanding indebtedness and other liabilities have been paid in full, and
there may not be sufficient assets remaining to pay amounts payable
 
                                       18
<PAGE>
on the Senior Preferred Stock and the Preferred Stock. The Preferred Stock also
effectively ranks junior in right of payment to all liabilities, including
indebtedness, of our subsidiaries. At December 31, 1998, we had approximately
$1,233.3 million of consolidated indebtedness and other liabilities, excluding
deferred credits for income taxes, outstanding ranking senior to the Preferred
Stock, and our subsidiaries had $1,073.3 million of liabilities, excluding
deferred credits for income taxes. See "Description of the Preferred
Stock--Ranking."
 
   
    If we issue Exchange Debentures in exchange for the Preferred Stock, the
Exchange Debentures will rank junior to all of our Senior Indebtedness, as such
term is defined under "Description of the Exchange Debentures", including
indebtedness under our 11 3/4% Senior Notes due 2007 and our credit facilities.
Our Exchange Debentures will also rank effectively junior to all liabilities,
including indebtedness, of our subsidiaries. In the event of our bankruptcy,
liquidation or reorganization, we will be able to pay obligations on the
Exchange Debentures only after all of our outstanding Senior Indebtedness has
been paid in full, and there may not be sufficient assets remaining to pay
amounts payable on the Exchange Debentures.
    
 
   
    The Preferred Stock permits us to issue as dividends additional shares of
preferred stock which rank equally with the Preferred Stock. The Exchange
Debentures permit us to issue as interest additional exchange debentures which
rank equally with the Exchange Debentures. The terms of the Preferred Stock and
the Exchange Debenture also permit us and our subsidiaries to incur additional
indebtedness and issue additional preferred stock, subject to certain
limitations. Such additional indebtedness may rank senior to, equally with or
junior to the Exchange Debentures, while additional indebtedness of our
subsidiaries will effectively rank senior to the Exchange Debentures. Such
additional preferred stock may rank senior (subject to a majority vote of the
Preferred Stock), equally or junior to the Preferred Stock, and will vote as
separate classes in most circumstances relating to the issuance of future senior
preferred stock.
    
 
   
WE ARE A HOLDING COMPANY AND DEPEND ON DISTRIBUTIONS FROM OUR SUBSIDIARIES TO
  MEET OUR OBLIGATIONS INCLUDING DIVIDENDS ON THE PREFERRED STOCK. THE PREFERRED
  STOCK IS EFFECTIVELY SUBORDINATED TO OUTSTANDING OBLIGATIONS OF OUR
  SUBSIDIARIES.
    
 
    We are a holding company with no direct operations and no significant assets
other than the stock of our subsidiaries. We depend on the cash flows of our
subsidiaries to meet our obligations, including our obligations to pay interest
and principal on our 11 3/4% Senior Notes due 2007, and dividends on the Senior
Preferred Stock and Preferred Stock. The ability of our subsidiaries to
distribute funds to us are and will be restricted by the terms of existing and
future indebtedness including our credit facilities. See "Description of Certain
Indebtedness--The Credit Facilities."
 
   
    Our subsidiaries are separate legal entities that have no obligation to pay
any amounts due with respect to the Preferred Stock and, if issued, the Exchange
Debentures or to make any funds available to us. As a result, if any of our
subsidiaries liquidate their assets, our right to any of the proceeds and the
consequent right of the holders of the Preferred Stock and, if issued, the
Exchange Debentures to participate in the distribution or realize proceeds from
those assets will be effectively subordinated to the claims of the creditors of
such subsidiary, including trade creditors and holders of indebtedness of such
subsidiary, including the Dobson/Sygnet 12 1/4% Senior Notes due 2008 and the
credit facilities. Unless a bankruptcy court were to subordinate our claim, we
will not be subordinated to such creditors if we are a creditor of such
subsidiary, although our claims would still be effectively subordinated to any
security interest in the assets of such subsidiary senior to any security
interest held by us.
    
 
WE MAY BE UNABLE TO PAY CASH DIVIDENDS ON THE PREFERRED STOCK OR INTEREST ON THE
  EXCHANGE DEBENTURES
 
    We must begin paying cash dividends on the Preferred Stock on January 15,
2003. Under the indenture governing our 11 3/4% Senior Notes due 2007, we may
pay cash dividends and make other distributions on or in respect of our capital
stock, including the Senior Preferred Stock and Preferred
 
                                       19
<PAGE>
   
Stock, only if certain financial tests are met. In addition, our credit
facilities limit the amount of cash available for dividends, loans and cash
distributions to us from our subsidiaries. Currently, the restrictions contained
in the indenture governing our 11 3/4% Senior Notes due 2007 and in our credit
facilities would prohibit us from paying cash dividends and would also prohibit
us from issuing Exchange Debentures in exchange for Preferred Stock. We cannot
assure you that our existing or future financing arrangements will permit us to
pay cash dividends on the Preferred Stock beginning January 15, 2003. In the
event that any of our financing agreements limit our ability to pay cash
dividends on the Preferred Stock when required, we will need to obtain waivers
of the limitation or refinance amounts outstanding under such agreements to make
such dividend payments. We cannot assure you that we would be able to obtain
waivers or refinance amounts outstanding under such agreements. Moreover, we
will not be able to pay cash dividends on the Preferred Stock, unless we first
have paid accrued and unpaid dividends on the Senior Preferred Stock. Our
failure to pay cash dividends on the Preferred Stock could result in a Voting
Rights Triggering Event as defined under "Description of the Preferred Stock".
    
 
   
RESTRICTIONS IMPOSED IN OUR GOVERNING INSTRUMENTS MAY ADVERSELY AFFECT OUR
  OPERATIONS.
    
 
    The instruments governing our indebtedness and that of our subsidiaries, the
certificates of designation with respect to the Senior Preferred Stock, the
Preferred Stock and our other preferred stock, and the terms of our credit
facilities impose significant operating and financial restrictions on us and on
our subsidiaries. Such restrictions significantly restrict, among other things,
our ability and that of our subsidiaries to incur additional indebtedness, pay
dividends, repay indebtedness prior to stated maturities, sell assets, make
investments, engage in transactions with stockholders and affiliates, issue
capital stock, create liens or engage in mergers or acquisitions. In addition,
the credit facilities require us to maintain certain financial ratios. These
restrictions could also limit our ability and that of our subsidiaries to obtain
future financings, make needed capital expenditures, withstand a future downturn
in our business or the economy in general, or otherwise conduct necessary
corporate activities. Our failure or that of our subsidiaries to comply with
these restrictions could lead to a default under the terms of such indebtedness
even though we are able to meet debt service and dividend obligations. In the
event of a default, the holders of such indebtedness could elect to declare all
such indebtedness to be due and payable and the holders of Preferred Stock could
obtain representation on our board of directors. We cannot assure you that we
and our subsidiaries would be able to make such payments or borrow sufficient
funds from alternative sources to make any such payment. Even if we could obtain
additional financing, we cannot assure you that we could obtain financing on
terms that are acceptable to us. In addition, indebtedness under each of the
credit facilities is secured by liens on assets. The pledge of our assets to
existing lenders could impair our ability to obtain favorable financing. See
"Description of Certain Indebtedness" and "Description of Capital Stock."
 
   
WE MAY BE UNABLE TO REPURCHASE OUR PREFERRED STOCK OR EXCHANGE DEBENTURES UPON A
  CHANGE OF CONTROL.
    
 
   
    We must offer to purchase the Preferred Stock or Exchange Debentures upon
the occurrence of a change of control at a purchase price equal to 101% of their
liquidation preference plus accrued and unpaid dividends or the principal amount
plus accrued and unpaid interest, as the case may be. See "Description of the
Preferred Stock--Change of Control" and "Description of the Exchange
Debentures--Change of Control."
    
 
   
    The terms of our credit facilities, the indenture governing our 11 3/4%
Senior Notes due 2007 and the certificate of designation for the Senior
Preferred Stock limit our ability to prepay the Preferred Stock or the Exchange
Debentures, including required prepayments following a change of control. Prior
to commencing an offer to purchase, we would be required to:
    
 
    - repay in full all indebtedness, including indebtedness under our credit
      facilities and the indenture governing our 11 3/4% Senior Notes due 2007
      and purchase all of our Senior Preferred Stock and other preferred stock
      and that of our subsidiaries that would prohibit the repurchase of the
      Preferred Stock or the Exchange Debentures, as the case may be, or
 
                                       20
<PAGE>
    - obtain any consents required to permit the repurchase.
 
   
    If we are unable to repay all of such indebtedness or are unable to obtain
the necessary consents, then we will be unable to offer to purchase the
Preferred Stock or the Exchange Debentures, resulting in a Voting Rights
Triggering Event under the Preferred Stock or an event of default under the
indenture governing the Exchange Debentures, if issued. We cannot assure you
that we will have enough funds available at the time of any change of control
offer to repurchase the Preferred Stock or the Exchange Debentures, as described
above.
    
 
   
    The events that constitute a change of control under the certificates of
designation for our Preferred Stock may also be events of default under the
credit 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 that we or our subsidiaries
sell assets that secure such debt in order to repay the lenders. In any such
case, our ability to raise cash to repurchase the Preferred Stock or the
Exchange Debentures, as the case may be, would be limited and would reduce the
practical benefit of the offer to purchase provisions to the holders of the
Preferred Stock or the Exchange Debentures. See "Description of Certain
Indebtedness."
    
 
   
THE SYSTEMS WE ACQUIRE MAY BE UNSUCCESSFUL AND MAY STRAIN OUR MANAGEMENT AND
  FINANCIAL RESOURCES.
    
 
    We are subject to risks that cellular systems that we acquire will not
perform as expected and that the returns from such systems will not support the
indebtedness we incur or equity we issue to acquire, or the capital expenditures
needed to develop, the systems. In addition, expansion of our operations may
place a significant strain on our management, financial and other resources. Our
ability to manage future growth will depend upon our ability to monitor
operations, control costs, maintain effective quality controls and significantly
expand our 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 efficiently at a
pace consistent with the growth of our business could have a material adverse
effect on our business, financial condition and results of operations. In
addition, the integration of acquired systems with existing operations will
require us to incur considerable expenses in advance of anticipated revenues and
may cause substantial fluctuations in our operating results. This will involve,
among other things, integration of switching, transmission, technical, sales,
marketing, billing, accounting, quality control, management, personnel, payroll,
regulatory compliance and other systems and operating hardware and software,
some of which may be incompatible with our existing systems. In addition,
telecommunications providers generally experience higher customer and employee
turnover rates during and after an acquisition. We cannot assure you that we
will be able to successfully integrate the systems acquired or any other
businesses we may acquire.
 
   
    We recently closed into escrow for our acquisitions of the FCC licenses for
Ohio 2 RSA and Texas 10 RSA. The purchase price of each of these acquisitions is
being held in escrow pending resolution of claims made against each seller's
title to the FCC license. We cannot assure you that these claims will be
resolved in favor of the respective sellers. If the claims are ultimately
resolved in a manner adverse to either seller, we could lose our license for the
affected RSA, although we would receive back our purchase price held in escrow.
However, if this occurred, we would need to either dispose of any improvements
we had made, redeploy them in another system to be operated by us or abandon the
assets. We could incur costs and expenses in connection with such disposal,
redeployment or abandonment. In addition, we would lose the benefit of owning
these properties and the future cash flows from the properties. Depending upon
how much we had invested in the affected RSA, how much of that investment could
sell or salvage and the potential future benefit therefrom, a loss of either of
these licenses could have an adverse effect on our operations and the loss of
revenues from either such system could have an adverse effect on our financial
condition.
    
 
                                       21

WE MAY NEED TO BUILDOUT PCS LICENSED AREAS.
    
 
   
    In April 1997, we obtained PCS licenses for nine markets as part of the FCC
"F" Block auction. Our right to hold and use each license depends on the
buildout of the PCS system to cover at least 25% of the population covered by
the license by April 2002. See "Business--Cellular Operations." We have
estimated that the capital expenditures relating to such a buildout would range
from $10.0 million to $30.0 million. The actual amount of the expenditures,
however, will depend in part on the PCS technology we select, the extent of our
buildout, costs at the time of buildout and the extent we, at our expense, must
relocate existing incumbent microwave licensees or compensate other PCS
licensees for their relocation costs. We will need additional financing for the
buildout of our PCS system. We cannot assure you that we will be able to obtain
such financing or, if such financing is available, that we can obtain it on
terms acceptable to us and within the limitations contained in the indenture
governing our 11 3/4% Senior Notes, the credit facilities, the certificates of
designation for the Preferred Stock, the Senior Preferred Stock and our other
preferred stock. If our subsidiary which holds the PCS licenses fails to satisfy
its installment financing obligations to the FCC, then the FCC may cancel our
PCS licenses. In addition, we would forfeit our investment in such PCS licenses,
and the FCC could sue the subsidiary for collection of any unpaid sums due to
the FCC plus forfeiture penalties. As of December 31, 1998, we had paid $1.0
million for such PCS licenses and owed the FCC an additional $4.1 million. We
cannot assure you that our PCS system will be profitable. The extent of
potential demand for PCS in our markets cannot be estimated with any degree of
certainty. We have no experience operating PCS systems. Sygnet holds no PCS
licenses.
    
 
   
    When the FCC first licensed cellular systems in the United States, it
specified the technical standards of systems operations to insure nationwide
compatibility between all cellular carriers. In contrast, the FCC has not
mandated the technology standard for PCS operations, leaving each licensee free
to select among several competing technologies, some of which are not compatible
with each other. We cannot assure you that the technical standards selected by
us will be the most widely used, or technologically sound. Also, because
handsets that use one PCS technology may not be operable on other systems, the
ability to offer PCS roamer service will be affected. To the extent most
competitors in the PCS industry select a competing technology that is not
compatible to the system selected by us, our PCS business may be adversely
affected. We have not yet finalized our plans with respect to the buildout of
our PCS licensed systems, nor have we selected the digital technology to be used
in such systems.
    
 
   
WE FACE INTENSE COMPETITION IN OUR BUSINESS AND MANY OF OUR COMPETITORS HAVE
  GREATER RESOURCES THAN DO WE.
    
 
   
    We face intense competition in many of the areas in which we operate.
Currently, the FCC authorizes only two cellular licensees to operate in each
license area. We compete in each of our markets with one other cellular licensee
for subscribers 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. Many of
our existing and potential competitors have greater financial, personnel,
technical, marketing and other resources than do we.
    
 
   
    Our cellular operations may face increased competition from entities that
use other communications technologies or other radio frequency spectrum such as
broadband PCS licensees and enhanced specialized mobile radio licensees. We may
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 and General Wireless Communications
Services. See "Business-- Competition."
    
 
                                       22
<PAGE>
   
OUR BUSINESS IS AFFECTED BY FREQUENT AND SIGNIFICANT TECHNOLOGICAL CHANGES WHICH
  MAY REQUIRE US TO SELECT NEW TECHNOLOGY BEFORE WE CAN ACCURATELY PREDICT ITS
  EFFECT ON OUR OPERATIONS.
    
 
    The telecommunications industry is subject to rapid and significant changes
in technology, including advancements protected by intellectual property laws.
Rapid and 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.
 
    We may be required to select in advance one technology over another. At the
time we must make our investment, it will be impossible to accurately predict
which technology may prove to be the most economic, efficient or capable of
attracting customer usage. There is also uncertainty as to the extent of
customer demand as well as the extent to which airtime and monthly access rates
may continue to decline.
 
   
OUR BUSINESS DEPENDS ON A LIMITED NUMBER OF KEY PERSONNEL.
    
 
    We are managed by a small number of management and operating personnel. The
loss of certain of these individuals could have a material adverse effect on us.
We believe that our ability to manage our planned growth successfully will
depend in large part on our continued ability to attract and retain highly
skilled and qualified personnel. See "--The systems we acquire may be
unsuccessful and may strain our management and financial resources" and
"Management."
 
WE DEPEND ON THIRD-PARTY SERVICE MARKS TO MARKET OUR PRODUCTS AND SERVICES. THE
  LOSS OF THE RIGHT TO USE THE SERVICE MARKS COULD ADVERSELY AFFECT OUR
  BUSINESS.
 
   
    We use the registered service marks CELLULAR ONE-Registered Trademark- and
AIRTOUCH-TM- CELLULAR-Registered Trademark- to promote the services we offer in
certain of our license areas. We have contracts with Cellular One Group, the
owner of the service mark, that govern our use of the CELLULAR
ONE-Registered Trademark- service mark. These contracts, which have five-year
terms, begin to expire in 2001. We have the option to renew these contracts for
two additional five-year terms. Our contract to use the AIRTOUCH-TM- CELLULAR
service mark is for an initial term of 20 years with provisions to extend the
term for successive five-year periods. See "Business--Service Marks." Under
these agreements, we must meet specified operating and service quality standards
for our systems. If these agreements are not renewed upon expiration or if we
fail to meet the applicable operating or service quality standards, our ability
both to attract new subscribers and retain existing subscribers could be
impaired. In addition, AT&T Wireless, which had been the single largest user of
the CELLULAR ONE-Registered Trademark- name, significantly reduced its use of
the brand name as a primary service mark. If for any reason beyond our control,
the names CELLULAR ONE-Registered Trademark- or AIRTOUCH-TM- CELLULAR were to
suffer diminished marketing appeal, our ability both to attract new subscribers
and retain existing subscribers could be materially impaired in the applicable
markets.
    
 
   
OUR BUSINESS IS REGULATED AND THERE IS POTENTIAL FOR ADVERSE REGULATORY CHANGE.
  WE MAY BE UNABLE TO OBTAIN REGULATORY APPROVALS.
    
 
   
    The FCC regulates the licensing, construction, operation, acquisition and
sale of our cellular systems, as well as the number of cellular and other
wireless licensees permitted in each of our markets. 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, some aspects of the Telecommunications Act
    
 
                                       23
<PAGE>
may place additional burdens upon us or subject us to increased competition and
increase our costs of doing business.
 
   
    Moreover, all cellular and PCS licenses are subject to renewal upon
expiration of each license's initial ten-year term. Grant of a cellular or PCS
renewal application is based upon FCC rules establishing a presumption in favor
of licensees that have complied with their regulatory obligations during the
ten-year license period. We have already received license renewals for several
of our cellular licenses and we are not aware of any circumstances that would
prevent the grant of any future renewal applications; however, we cannot assure
you that the FCC will grant any future renewal applications or that such
applications will be free of challenge. See "Business--Regulation."
    
   
EQUIPMENT FAILURE AND NATURAL DISASTERS MAY ADVERSELY AFFECT OUR OPERATIONS.
    
 
    We carry business interruption, casualty and property insurance in amounts
we believe adequate to cover the financial risks associated with any major
equipment failure or natural disaster. However, a major equipment failure or a
natural disaster affecting our central switching offices, our microwave links or
certain of our cell sites could have a material adverse effect on our
operations.
 
   
OUR RELIANCE ON ONE VENDOR FOR OUR CUSTOMER BILLING MAY ADVERSELY AFFECT THE
  TIMING OF OUR RECEIPT OF FUNDS.
    
 
   
    We rely primarily on one vendor to produce our customer billings. We are in
the process of implementing a new version of billing software throughout our
markets. If we are unable to implement this new software or if this or our
present billing vendor for any reason were to encounter significant problems in
the performance of its billing functions for us, our ability to generate
billings to our customers would be materially impaired, until we could establish
a new arrangement.
    
 
   
CONFLICTS OF INTEREST MAY EXIST WITH OUR CONTROLLING STOCKHOLDERS.
    
 
   
    Everett R. Dobson, our Chairman of the Board, President and Chief Executive
Officer, and his affiliates beneficially own approximately 80% of the combined
voting power of all classes of our outstanding voting stock on a fully diluted
basis. Certain decisions concerning our operations or financial structure may
present conflicts of interest between the holders of our voting stock and the
holders of the Preferred Stock and, if issued, the Exchange Debentures. In
addition, holders of voting stock may have an interest in pursuing acquisitions,
divestitures, financings or other transactions that, in their judgment, could
enhance their equity investment, even though such transactions might involve
risk to the holders of the Preferred Stock and, if issued, the Exchange
Debentures.
    
 
   
THERE ARE CERTAIN FEDERAL INCOME TAX CONSEQUENCES WHICH WILL AFFECT HOLDERS OF
  PREFERRED STOCK AND EXCHANGE DEBENTURES.
    
 
    Because we may pay dividends on the Preferred Stock by distributing
additional shares of Preferred Stock, compliance with U.S. federal withholding
tax rules would be difficult with respect to investors who are not U.S. persons.
Accordingly, we consider the Preferred Stock to be an inappropriate investment
for any person who or which is not a U.S. person.
 
    Distributions of cash or, to the extent of their fair market value,
distributions of additional shares of Preferred Stock will generally be treated
as dividends, taxable as ordinary income to the extent of our current and
accumulated earnings and profits, as determined under U.S. federal income tax
principles. However, we presently do not have any current or accumulated
earnings and profits as determined under U.S. federal income tax principles and
it is unlikely to have current or accumulated earnings and profits in the
foreseeable future. As a result, until such time as we have earnings and
profits, distributions of cash or additional shares of Preferred Stock on the
Preferred Stock will be treated as a nontaxable return of capital and will be
applied against and reduce the adjusted tax basis, but not below zero, in the
hands of each holder of the shares of Preferred Stock on which such distribution
is made, thus increasing the amount of any gain or reducing the amount of any
loss which would otherwise be realized by such holder upon the
 
                                       24
<PAGE>
sale or other disposition of those shares of Preferred Stock. In the case of
distributions of additional shares of Preferred Stock, however, such basis
reduction largely should be offset from an overall standpoint by a corresponding
amount of tax basis for a holder in the additional shares of Preferred Stock. A
holder would recognize gain to the extent any distributions were to exceed our
current or accumulated earnings and profits and the adjusted tax basis of the
holder in the Preferred Stock.
 
    As we expect the redemption price of the Preferred Stock to exceed its issue
price by more than a minimum amount, the difference or the "redemption premium"
generally will be taxable as a constructive distribution of additional Preferred
Stock to a holder over a certain period under a constant interest rate method
similar to that described below for accruing original issue discount on the
Exchange Debentures. However, to the extent we lack current or accumulated
earnings and profits for a taxable year to which a constructive distribution
relates
 
    - a holder should not recognize taxable income or gain as a result of the
      constructive distribution,
 
    - there should be no net effect on the holder's adjusted tax basis of the
      Preferred Stock as a result of the constructive distribution.
 
    To the extent we have current or accumulated earnings and profits for a
taxable year to which a constructive distribution relates, the distribution will
be taxable currently to the holder as a dividend even though the holder does not
receive any actual distribution and will produce a corresponding increase in the
adjusted tax basis of the Preferred Stock with respect to which the distribution
is deemed to have been made. See "Federal Income Tax Considerations--Redemption
Premium."
 
   
    Additional shares of Preferred Stock that we distribute as a dividend on our
previously issued Preferred Stock will also have redemption premium if the
redemption price of such Preferred Stock exceeds the fair market value of the
additional shares of Preferred Stock when distributed by more than a minimum
amount. Such redemption premium may differ from that attributable to the shares
of Preferred Stock that we have previously issued. Therefore, any such
additional shares of the Preferred Stock we distribute may not be fungible with
the shares of the Preferred Stock previously issued.
    
 
    Further, if holders of Preferred Stock receive additional shares of
Preferred Stock as a distribution on previously issued Preferred Stock, such
holders would, to the extent we have earnings and profits for U.S. federal
income tax purposes, be required to include currently in gross income for U.S.
federal income tax purposes the fair market value of such additional shares,
even though such holders have not received any cash with respect to such
distribution.
 
    Upon a redemption of Preferred Stock in exchange for Exchange Debentures,
the holder generally will have a capital gain or loss equal to the difference
between the issue price of the Exchange Debentures received and the holder's
adjusted tax basis in the Preferred Stock redeemed, except to the extent all or
a portion of the Exchange Debentures received is treated as a dividend payment.
Because we have the option through January 15, 2003 to pay interest on the
Exchange Debentures by issuing additional Exchange Debentures, any Exchange
Debentures issued prior to that date will be treated as issued with original
issue discount, or "OID" for U.S. federal income tax purposes, unless under
special rules for interest holidays the amount of OID is treated as minimum. If
the Exchange Debenture has OID in excess of the minimum amount, holders would
have to accrue all such OID into income over the entire term of the Exchange
Debentures, but would not treat the receipt of stated interest on the Exchange
Debentures as interest for U.S. federal income tax purposes. The Exchange
Debentures may also be subject to the rules for "applicable high yield discount
obligations," in which case our deduction for OID on the Exchange Debentures
will be substantially deferred, and a portion of such deduction may be
disallowed.
 
    For a discussion of these and other relevant tax issues, see "Federal Income
Tax Considerations."

POTENTIAL FAILURE OF COMPUTER SYSTEMS TO BECOME YEAR 2000 COMPLIANT MAY
  ADVERSELY AFFECT OUR OPERATIONS.
    
 
    The Year 2000 issue exists because many computer systems and applications,
including those embedded in equipment and facilities, use two digit rather than
four digit date fields to designate an applicable year. As a result, the systems
and applications may not properly recognize the year 2000 or process data that
includes it, potentially causing data miscalculations, inaccuracies, operational
malfunctions or failures.
 
    In April 1998, we established a multi-disciplined team to perform a Year
2000 impact analysis. The team consists of representatives from each of our
lines of business, as well as representatives from key corporate departments,
and is headed by a full-time Year 2000 compliance manager. The team created a
Year 2000 assessment methodology which brought a structured approach to the
assessment and management reporting process, as well as disaster recovery
approach.
 
   
    To date, we have completed an inventory of our automated systems and
services and an impact analysis that identified significant risk areas by line
of business, specific compliance requirements and costs and estimated completion
dates for affected systems. We have been in contact with all of the vendors of
products and services that we believe are critical to our operations. The
representation from our vendors pertaining to Year 2000 compliance has come in
writing directly to us, in contracts, and by accessing Year 2000 information
available at their Web sites. While all of the vendors have provided some type
of assurance that their products will be Year 2000 compliant, not all have
provided us expressly with a "Year 2000 Compliance Statement" and/or a "Year
2000 Warranty." If our automated systems and those of our vendors are not year
2000 compliant, we could experience interruptions in services provided by and to
us, which could materially reduce our operating cash flow. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" for
further discussion of the Year 2000 issue and the potential impact on our
business.
    
 
   
THERE IS NO PUBLIC MARKET FOR THE PREFERRED STOCK AND THE OLD SHARES HAVE
  RESTRICTIONS ON TRANSFERABILITY.
    
 
   
    There has not been an established trading market for the Preferred Stock.
The initial purchaser has informed us that it does not currently intend to make
a market in the Preferred Stock. Accordingly, we cannot assure you as to the
development or liquidity of any market for the Preferred Stock. If a market for
the Preferred Stock were to develop, the Preferred Stock could trade for less
than the initial offering price, depending upon many factors, including
prevailing interest rates, our operating results and the markets for similar
securities, and such market may cease to continue at any time.
    
 
   
    Your old shares were not 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 effective
registration statement. We have registered the new shares under the Securities
Act and are obligated to use our best efforts to complete an exchange offer for
the old shares or register resales of the old shares under the Securities Act,
but we cannot assure you that a trading market for the Preferred Stock will be
liquid or will develop at all.
    
 
   
THERE MAY BE ADVERSE CONSEQUENCES OF A FAILURE TO EXCHANGE.
    
 
   
    Untendered outstanding old shares that are not exchanged for new shares
pursuant to the exchange offer will remain restricted securities. Outstanding
old shares will continue to be subject to the following restrictions on
transfer:
    
 
   
    - outstanding old shares may be resold only if registered pursuant to the
      Securities Act, if an exemption from registration is available thereunder,
      or if neither such registration nor such exemption is required by law,
    
 
   
    - outstanding old shares shall bear a legend restricting transfer in the
      absence of registration or an exemption therefrom and
    
 
                                       26
<PAGE>
   
    - a holder of outstanding old shares who desires to sell or otherwise
      dispose of all or any part of its outstanding old shares under an
      exemption from registration under the Securities Act, if requested by us,
      must deliver to us an opinion of independent counsel experienced in
      Securities Act matters, reasonably satisfactory in form and substance to
      us, that such exemption is available.
    
 
FORWARD-LOOKING STATEMENTS
 
   
    The statements, other than statements of historical facts included in this
prospectus, including the description of our plans, our strategies, planned
capital expenditures, Year 2000 preparedness, acquisitions and related
financing, and anticipated cost savings, are forward-looking statements made
pursuant to the safe harbor provisions of the Private Securities Litigation
Reform Act of 1995. You can generally identify forward-looking statements
generally by the use of forward-looking terminology such as "may," "will,"
"expect," "intend," "estimate," "anticipate" or "believe." We believe that the
expectations reflected in such forward-looking statements are accurate. However,
our actual future performance will differ materially from such statements. These
plans involve a number of risks and uncertainties. Important factors that could
cause actual capital expenditures, acquisitions activity, or our performance to
differ materially from its plans include, without limitation:
    
 
    - our ability to satisfy the financial covenants of our existing and future
      debt instruments and to raise additional capital;
 
    - our ability to integrate acquired systems with our 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. We caution you 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.
    
 
   
                                USE OF PROCEEDS
    
 
   
    This exchange offer is intended to satisfy our obligations under our
Registration Rights Agreement dated as of December 25, 1998 with NationsBanc
Montgomery Securities LLC, as the initial purchaser of the old shares. We will
not receive any cash proceeds from the issuance of the new shares. We will only
receive old shares equal in number to the number of new shares that we issue in
the exchange offer.

                               THE EXCHANGE OFFER
    
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
   
    We initially issued an aggregate of 64,646 old shares on December 23, 1998
to NationsBanc Montgomery Securities LLC (the "Initial Purchaser") in reliance
on Section 4(2) of the Securities Act. The Initial Purchaser subsequently
offered and sold a portion of the old shares only to "qualified institutional
buyers" as defined in and in compliance with Rule 144A. Subsequently and through
April 15, 1999, we have issued 2,500 additional old shares as the payment of
dividends on the outstanding Preferred Stock.
    
 
   
    In connection with the sale of the old shares, we entered into a
registration rights agreement, which requires us
    
 
   
    - to cause the old shares to be registered under the Securities Act, or
    
 
   
    - to file with the Securities and Exchange Commission ("SEC") a registration
      statement under the Securities Act with respect to an issue of new shares
      identical in all material respects to the Old Shares, and
    
 
    - use our 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 shares the opportunity to exchange their old shares for
      a like principal amount of new shares, 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.
    
 
   
    We have filed a copy of the registration rights agreement as an exhibit to
the registration statement of which this prospectus is a part. We are making the
exchange offer to satisfy our obligations under the registration rights
agreement. The term "holder" with respect to the exchange offer means any person
in whose name old shares are registered on our books or any other person who has
obtained a properly completed stock power from the registered holder, or any
person whose old shares are held of record by The Depository Trust Company
("DTC") who desires to deliver such old shares by book-entry transfer at DTC.
    
 
   
    We have not requested, and do not intend to request, an interpretation by
the staff of the SEC with respect to whether the new shares issued in the
exchange offer in exchange for the old shares 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. Based on interpretations
by the staff of the SEC set forth in no-action letters issued to third parties,
we believe the new shares issued in exchange for old shares may be offered for
resale, resold and otherwise transferred by any holder without compliance with
the registration and prospectus delivery provisions of the Securities Act
provided that:
    
 
    - you are not a broker-dealer,
 
    - you are not our "affiliate" within the meaning of Rule 405 under the
      Securities Act
 
   
    - you acquire the new shares in the ordinary course of your business and
      that you have no arrangement or understanding with any person to
      participate in the distribution of the new shares.
    
 
   
    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
shares or who is our affiliate may not rely upon such interpretations by the
staff of the SEC and, in the absence of an exemption, must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any secondary resale transaction. Any holder to comply with such
requirements may incur liabilities under the Securities Act for which the holder
is not indemnified by us. Each broker-dealer (other than an affiliate of ours)
that receives new shares for its own account in the exchange offer must
acknowledge that it will deliver a
    
 
                                       28
<PAGE>
   
prospectus meeting the requirements of the Securities Act in connection with any
resale of new shares. 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. We have agreed
that, for a period of 180 days after the exchange date, we will make the
prospectus available to any broker-dealer for use in connection with any such
resale. See "Plan of Distribution."
    
 
   
    We are not making the exchange offer to, nor will we accept surrenders for
exchange from, holders of old shares in any jurisdiction in which this exchange
offer or its acceptance would not comply with the securities or blue sky laws.
    
 
    By tendering in the exchange offer, you will represent to us that, among
other things:
 
   
    - you are acquiring the new shares in the exchange offer in the ordinary
      course of your business, whether or not you are a holder,
    
 
   
    - you do not have an arrangement or understanding with any person to
      participate in the distribution of the new shares,
    
 
   
    - you are not a broker-dealer, or you are a broker-dealer but will not
      receive new shares for your own account in exchange for old shares,
      neither you nor any other person is engaged in or intends to participate
      in the distribution of the new shares, and
    
 
   
    - you are not our "affiliate" within the meaning of Rule 405 under the
      Securities Act or, if you are our "affiliate," you will comply with the
      registration and prospectus delivery requirements of the Securities Act to
      the extent applicable.
    
 
   
    Following the completion of the exchange offer, no shares of Preferred Stock
will be entitled to the contingent increase in dividend rate applicable to the
old shares. Nor will holders of Preferred Stock have any further registration
rights, and the old shares 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 shares could be adversely affected. See
"Risk Factors--There may be adverse consequences of a failure to exchange."
    
 
    Participation in the exchange offer is voluntary and you should carefully
consider whether to accept. We urge you to consult your financial and tax
advisors in making your 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, we will accept for exchange any and
all old shares validly tendered and not withdrawn prior to 5:00 p.m., New York
City time, on the expiration date. We will issue one new share in exchange for
each old share accepted in the exchange offer. You may tender some or all of
your old shares in the exchange offer.
    
 
   
    The form and terms of the new shares will be identical in all material
respects to the form and terms of the old shares except that the new shares will
be registered under the Securities Act and, therefore, certificates representing
new shares will not bear legends restricting their transfer. The new shares will
be treated as a single class with any old shares that remain outstanding. We are
not conditioning the exchange offer upon any minimum number of old shares being
tendered for exchange.
    
 
   
    As of March 31, 1999, 65,151 old shares were outstanding.
    
 
   
    You do not have any appraisal or dissenters' rights under the Oklahoma
General Corporation Act or the certificate of designation in connection with the
exchange offer. We are sending this prospectus, together with the letter of
transmittal, to all registered holders of old shares. We have not fixed any
record date for determining record holders of old shares entitled to participate
in the exchange offer. We intend
    
 
                                       29
<PAGE>
   
to conduct the exchange offer in accordance with the provisions of the
registration rights agreement and the applicable requirements of the Exchange
Act, and the rules and regulations of the SEC. Old shares which are not tendered
for exchange in the exchange offer will remain outstanding and dividends will
continue to accrue, but such old shares will not be entitled to any rights or
benefits under the registration rights agreement.
    
 
   
    We will be deemed to have accepted validly tendered old shares when, as and
if we have given oral or written notice to the exchange agent. The exchange
agent will act as agent for the tendering holders for the purposes of receiving
the New Shares from us. If we do not accept any tendered old shares for exchange
because of an invalid tender or the occurrence of certain other events
identified in this prospectus, we will return the certificates for the
unaccepted old shares, without expense, to the tendering holder as promptly as
practicable after the expiration date.
    
 
   
    You will not be required to pay brokerage commissions or fees or, subject to
the instructions in the letter of transmittal, transfer taxes if you tender old
shares in the exchange offer. We 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 exchange offer expires at 5:00
p.m., New York City time, on         , 1999, unless we, in our sole discretion,
extend the exchange offer, in which case the expiration date will be the latest
date and time to which the exchange offer is extended. Although we do not intend
to extend the exchange offer at this time, we reserve the right to extend the
exchange offer at any 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 shares 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 shares for old shares
will be as soon as practicable following the expiration date.
    
 
    We reserve the right, in our sole discretion,
 
   
    - to delay accepting any old shares, 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" have not been satisfied, by
      giving oral or written notice of such delay, extension or termination to
      the exchange agent, or
    
 
    - to amend the terms of the exchange offer in any manner.
 
    We will, as promptly as practicable, notify you orally or in writing if
there is any delay in acceptance, extension, termination or amendment. If we
amend the exchange offer in any manner determined by us to constitute a material
change, we will promptly disclose the amendment by means of a prospectus
supplement that we will distribute to you. We will also 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 that period.
 
   
    In all cases we will issue new shares for old shares accepted for exchange
in the exchange offer only after the exchange agent timely receives a properly
completed and duly executed letter of transmittal and all other required
documents. We reserve the right to waive any conditions of the exchange offer or
defects or irregularities in the tender of old shares. If any tendered old
shares are not accepted for any reason set forth in the terms and conditions of
the exchange offer or if old shares are submitted for a greater number of shares
than the holder desires to exchange, such unaccepted or non-exchanged old shares
or substitute old shares 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.
    
 
                                       30
<PAGE>
   
    DIVIDENDS ON THE NEW SHARES.  You will not receive accrued dividends on old
shares that are accepted for exchange at the time of exchange. However, we will
pay accrued but unpaid dividends on exchanged old shares, rounded to the nearest
whole share, in new shares on the first dividend payment date following
consummation of the exchange offer.
    
 
   
    PROCEDURES FOR TENDERING OLD SHARES.  Your tender of old shares through one
of the procedures set forth below will constitute an agreement between you and
us in accordance with the terms and subject to the conditions set forth in this
prospectus and in the letter of transmittal. In order to tender old shares, you
must
    
 
   
    - properly complete and sign a letter of transmittal or a facsimile thereof
      and deliver the same, together with any corresponding certificate or
      certificates representing the old shares being tendered 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,
    
 
    - comply with the procedure for book-entry transfer described below, or
 
    - comply with the guaranteed delivery procedures described below.
 
   
    You do not need to have our signature guaranteed if the tendered old shares
are registered in the name of the signer of the letter of transmittal and the
new shares to be issued in exchange are to be issued and any untendered old
shares are to be reissued in the name of the registered holder, including any
participant in DTC (also referred to as a book-entry facility) whose name
appears on a security listing as the owner of old shares. In any other case you
must be endorse the tendered old shares or accompany them with written
instruments of transfer in form satisfactory to us and duly executed by the
registered holder. In addition, 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:
    
 
    - The Securities Transfer Agents Medallion Program (STAMP),
 
    - The New York Stock Exchange Medallion Signature Program (MSF), or
 
    - The Stock Exchange Medallion Program (SEMP).
 
   
    If the new shares or old shares not exchanged are to be delivered to an
address other than that of the registered holder appearing on the note register
for the old shares, the signature in the letter of transmittal must be
guaranteed by an eligible institution.
    
 
   
    YOU MUST ELECT, AND ACCEPT THE RISK OF, THE METHOD OF DELIVERY OF OLD
SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE
EXCHANGE AGENT. IF SUCH DELIVERY IS BY MAIL, WE RECOMMEND THAT REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES, YOU
SHOULD ALLOW SUFFICIENT TIME TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE
EXPIRATION DATE. DO NOT SEND ANY LETTER OF TRANSMITTAL OR OLD SHARES TO US. YOU
MAY REQUEST YOUR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES
OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR YOU.
    
 
   
    We understand 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 shares. We further
understand 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 shares for the purpose of facilitating the exchange offer,
and any participant may make book-entry delivery of old shares by causing DTC to
transfer such old shares into the exchange agent's account in accordance with
DTC's ATOP procedures for transfer. However, the exchange of the old shares 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, and any other documents required by the letter of
transmittal.
    
 
                                       31
<PAGE>
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 shares which are the subject of such Book-Entry Confirmation,
    
 
    - the participant has received and agrees to be bound by the terms of the
      letter of transmittal, and
 
    - we may enforce such agreement against such participant.
 
    A tender will be deemed to have been received as of the date when
 
   
    - the tendering holder's properly completed and duly signed letter of
      transmittal accompanied by the old shares or a confirmation of book-entry
      transfer of such old shares into the exchange agent's account at DTC, is
      received by the exchange agent, or
    
 
    - a notice of guaranteed delivery or letter, telegram or facsimile
      transmission to similar effect from an eligible institution is received by
      the exchange agent.
 
   
    Issuances of new shares in exchange for old shares tendered pursuant to a
notice of guaranteed delivery or letter, telegram or facsimile transmission to
similar effect 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 shares.
    
 
   
    We will determine all questions as to the validity, form, eligibility
including time of receipt, and acceptance for exchange of any tender of old
shares in our reasonable judgment. Our determination will be final and binding.
We reserve 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 our counsel, be
unlawful. We also reserve the absolute right to waive any of the conditions of
the exchange offer or any defect or irregularity in the tender of any old
shares. Neither we, 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 shares 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 shares are submitted
in principal amount greater than the principal amount of old shares being
tendered by such tendering holder, such unaccepted or non-exchanged old shares
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, we reserve the right in our sole discretion
 
   
    - to purchase or make offers for any old shares that remain outstanding
      subsequent to the expiration date, and
    
 
   
    - to the extent permitted by applicable law, to purchase old shares 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 you desire to accept the exchange offer
and time will not permit a letter of transmittal or old shares to reach the
exchange agent before the expiration date or the procedure for book-entry
transfer cannot be completed on a timely basis, you may effect a tender 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,
 
   
    - setting forth the name(s) in which the old shares are registered and the
      certificate number(s) of the old shares to be tendered,
    
 
    - stating that the tender is being made thereby, and
 
                                       32
<PAGE>
   
    - 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 shares, in proper form for transfer
      or a confirmation of book-entry transfer of such old shares 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 shares 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, we may, at our 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.
 
   
    The party tendering old shares for exchange (the "transferor") exchanges,
assigns and transfers the old shares to us and irrevocably constitutes and
appoints the exchange agent as the transferor's agent and attorney-in-fact to
cause the old shares 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 shares and to acquire new shares issuable
upon the exchange of such tendered old shares, and that, when the same are
accepted for exchange, we will acquire good and unencumbered title to the
tendered old shares, 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 us to be necessary or desirable to complete the exchange, assignment and
transfer of tendered old shares or to transfer ownership of such old shares 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 us the
representations set forth above under the heading "--Purpose and Effect of the
Exchange Offer."
 
   
    WITHDRAWAL OF TENDERS OF OLD SHARES.  Except as otherwise provided herein,
tenders of old shares 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 shares 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
    
 
   
    - specify the name of the person having deposited the old shares to be
      withdrawn (the "depositor"),
    
 
   
    - identify the old shares to be withdrawn, including the certificate number
      or numbers and principal amount of such old shares,
    
 
   
    - contain a statement that the holder is withdrawing its election to have
      such old shares exchanged,
    
 
   
    - be signed by the holder in the same manner as the original signature on
      the letter of transmittal by which such old shares were tendered,
      including any required signature guarantees, or be accompanied by
      documents of transfer sufficient to have the Trustee with respect to the
      old shares register the transfer of such old shares in the name of the
      person withdrawing the tender, and
    
 
   
    - specify the name in which any such old shares are to be registered, if
      different from that of the depositor.
    
 
   
    If old shares 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
    
 
                                       33
<PAGE>
   
questions as to the validity, form and eligibility, including time of receipt,
of such notices will be determined by us, and our determination shall be final
and binding on all parties. Any old shares so withdrawn will be deemed not to
have been validly tendered for purposes of the exchange offer and no new shares
will be issued with respect thereto unless the old shares so withdrawn are
validly retendered. Any old shares 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 shares may be
retendered by following one of the procedures described above under
"--Procedures for Tendering Old Shares" 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, we are not required to accept for exchange, or exchange new
shares for, any old shares, and may terminate the exchange offer as provided
herein before the acceptance of such old shares, if:
    
 
    - any statute, rule or regulation shall have been enacted, or any action
      shall have been taken by any court or governmental authority which, in our
      reasonable judgment, would prohibit, restrict or otherwise render illegal
      consummation of the exchange offer; or
 
    - any change, or any development involving a prospective change, in our
      business or financial affairs or any of our subsidiaries has occurred
      which, in our sole judgment, might materially impair our ability to
      proceed with the exchange offer or materially impair the contemplated
      benefits of the exchange offer to us; or
 
    - there shall occur a change in the current interpretations by the staff of
      the SEC which, in our reasonable judgment, might materially impair our
      ability to proceed with the exchange offer.
 
    If we determine in our reasonable judgment that any of the above conditions
are not satisfied, we may
 
   
    - refuse to accept any old shares and return all tendered old shares to the
      tendering holders,
    
 
   
    - extend the exchange offer and retain all old shares tendered prior to the
      expiration date, subject, however, to the right of holders to withdraw
      such old shares, or
    
 
   
    - waive such unsatisfied conditions with respect to the exchange offer and
      accept all validly tendered old shares which have not been withdrawn.
    
 
    If such waiver constitutes a material change to the exchange offer, we will
promptly disclose such waiver by means of a prospectus supplement that will be
distributed to the registered holders, and we 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.
 
EXCHANGE AGENT
 
    We have appointed United States Trust Company of New York as exchange agent

FEES AND EXPENSES
 
    We will bear all fees and the expenses of soliciting tenders. The principal
solicitation is being made by mail; however, additional solicitation may be made
by telecopy, telephone or in person by our officers and regular employees and
those of affiliates. No additional compensation will be paid to any such
officers and employees who engage in soliciting tenders.
 
   
    We have 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. However, we 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.
We 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 shares and in handling or forwarding tenders for
exchange.
    
 
    The cash expenses to be incurred in connection with the exchange offer will
be paid by us and are estimated in the aggregate to be approximately $100,000.
These expenses include fees and expenses of the exchange agent and transfer
agent and registrar, accounting and legal fees and printing costs, among others.
 
   
    We will pay all transfer taxes, if any, applicable to the exchange of the
old shares for new shares in the exchange offer. If, however, new shares, or old
shares 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 shares tendered or if a transfer tax is imposed for
any reason other than the exchange of the old shares 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 shares that are not exchanged for new shares in the exchange offer
will remain restricted securities within the meaning of Rule 144 of the
Securities Act. Accordingly, such old shares may be resold only
    
 
                                       35
<PAGE>
    - to us or any of our subsidiaries,
 
    - to a qualified institutional buyer in compliance with Rule 144A,
 
   
    - 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 shares and, if such transfer is in respect of an aggregate
      principal amount of old shares at the time of transfer of less than
      $100,000, an opinion of counsel acceptable to us that such transfer is in
      compliance with the Securities Act,
    
 
    - outside the United States in compliance with Rule 904 under the Securities
      Act,
 
    - pursuant to the exemption from registration provided by Rule 144 under the
      Securities Act, if available, or
 
    - pursuant to an effective registration statement under the Securities Act.
 
   
    The liquidity of the old shares could be adversely affected by the exchange
offer. Following the consummation of the exchange offer, holders of the
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 shares.
    
 
    FIRPTA TREATMENT
 
    At present, we believe that we are not a U.S. real property holding company
within the meaning of Section 897(c)(2) of the Code, and that we do not expect
to become a U.S. real property holding company in the forseeable future. No
assurance can be given, however, that the IRS will not reach a different
conclusion or that our expectation for the future will not change. If we are
found to be a U.S. real property holding company, then a Non-United States
holder of Preferred Stock may be subject to U.S. federal income tax in respect
of gain realized on the sale or other disposition of the Preferred Stock,
including an exchange for Exchange Debentures or a redemption, as if the gain
represented income effectively connected with a U.S. trade or business. A
Non-United States holder will not be subject to such tax, however, if the
Preferred Stock is regularly traded on an established securities market at the
time of a sale or other disposition, and the holder has not owned more than 5%
of the Preferred Stock at any time during the five-year period, or shorter
holding period for the Preferred Stock, ending on the sale or disposition date.
 
    INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    In general, information reporting requirements will apply to certain
payments of dividends, interest, OID and premium and to the proceeds of sales of
Exchange Debentures and Preferred Stock made to Non-United States holders, other
than certain exempt recipients (such as corporations). In addition, a backup
withholding tax of 31% may apply to such payments unless the Non-United States
Holder provides appropriate certification of foreign status. Prospective
Non-United States holders should consult their own tax advisors regarding the
application of the new Treasury regulations to an investment in the Preferred
Stock and Exchange Debentures.
 
   
    THE FOREGOING SUMMARY DOES NOT DISCUSS ALL ASPECTS OF U.S. FEDERAL INCOME
TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR PARTICULAR CIRCUMSTANCES
AND INCOME TAX SITUATION. YOU SHOULD CONSULT YOUR OWN TAX ADVISOR AS TO THE
SPECIFIC TAX CONSEQUENCES THAT WOULD RESULT FROM YOUR PURCHASE, OWNERSHIP AND
DISPOSITION OF THE PREFERRED STOCK AND THE EXCHANGE DEBENTURES, INCLUDING THE
APPLICATION AND EFFECT OF STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE
POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.

                 SELECTED CONSOLIDATED FINANCIAL AND OTHER DATA
    
 
    The following table sets forth certain of our historical consolidated
financial data as of and for each of the five years ended December 31, 1998. Our
consolidated financial data as of and for each of the years in the period 1994
to 1998 have been derived from our consolidated financial statements which have
been audited by Arthur Andersen LLP. Acquisitions we made during 1996, 1997 and
1998 materially affect the comparability of data from one period to another. You
should read the data in conjunction with "Pro Forma Condensed Consolidated
Financial Data," "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and our financial statements and the related notes
included elsewhere in this prospectus.
 
    The historical data we present for each of the years ended December 31,
1996, 1997 and 1998 include the operations of acquisitions we made, as
applicable during those years, from the date of each acquisition.
 
    Our earnings were insufficient to cover combined fixed charges and preferred
stock dividends by $2.3 million for the year ended December 31, 1996, by $21.6
million for the year ended December 31, 1997 and by $85.8 million for the year
ended December 31, 1998. We define "earnings" 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.
 
    We determine cellular penetration by dividing our total ending cellular
subscribers for the period by the estimated total population covered by
applicable FCC cellular licenses or authorizations that we hold.
 
    The average monthly revenue per cellular subscriber excluded roaming revenue
and equipment revenue.

                        NOTES TO THE UNAUDITED PRO FORMA
                      CONSOLIDATED STATEMENT OF OPERATIONS
                          YEAR ENDED DECEMBER 31, 1998
    
 
(1) This reflects the results of operations for California 4 for the three month
    period in 1998 during which we did not own the property.
 
(2) This reclassifies certain operating expenses to conform with our historical
    presentation.
 
(3) This eliminates costs that Sygnet incurred related to the consummation of
    our acquisition of the Sygnet.
 
(4) This reflects the additional depreciation and amortization resulting from
    the allocation of purchase price to property and equipment, cellular license
    acquisition costs and intangible assets. We depreciate property and
    equipment over two to ten years, cellular license acquisition costs over 15
    years and intangible assets over five to ten years. The 15 year period we
    use for cellular license acquisition costs is based primarily on our
    internal analysis of the recovery period for our cellular investments, which
    indicates that we will recover such costs through operations over a period
    of not more than 15 years. Other factors that we consider 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--Our business is subject to intense
    competition" and "--Our business is affected by frequent and significant
    technological changes."
 
(5) This reflects:
 
   
    - the $.7 million of interest expense relating to the $28.4 million of
      indebtedness that we incurred under the DCOC Facility in connection with
      our acquisition of California 4 (assuming an interest rate of 9.0% per
      annum),
    
 
   
    - the elimination of $.3 million of interest expense associated with the
      indebtedness of California 4 which we did not assume,
    
 
    - the elimination of $27.9 million of interest expense associated with the
      Sygnet notes and Sygnet's existing bank facility which we repaid as part
      of the Sygnet acquisition,
 
    - $24.0 million of interest expense relating to the $200.0 million of the
      Dobson/Sygnet notes,
 
    - $33.4 million of interest expense relating to the borrowings under our new
      credit facilities (assuming a weighted average rate of 8.38%),
 
    - $.1 million of interest expense relating to the unused principal amounts
      of our new credit facilities (assuming a commitment fee of .5%),
 
    - $3.8 million of amortization of deferred financing costs relating to the
      estimated $38.7 million of debt issuance costs we incurred in connection
      with our offering of the Dobson/Sygnet notes,
 
    - $1.2 million of amortization of deferred financing costs relating to the
      estimated $10.8 million of debt issuance costs we incurred in connection
      with our new credit facilities,
 
    - $1.4 million of interest relating to the $17.5 million of borrowings under
      the Dobson Tower Company credit facility,
 
    - the elimination of $.3 million of interest related to the $25.0 million
      borrowed under the DOC Facility to pay the initial deposit for our
      acquisition of Sygnet and
 
    - $1.0 million of interest expense related to the $15.0 million of
      borrowings under existing credit facilities.
 
                                       43
<PAGE>
   
(6) This reflects an adjustment to income tax expense for the effects of our
    acquisitions of Sygnet and California 4, and the related financing, assuming
    a 38% effective tax rate.
    
 
   
(7) This reflects dividends on the Preferred Stock, including the amortization
    of the issuance costs and discounts with respect thereto as follows:
    
 
   
    - $10.1 million for the Senior Preferred Stock that we sold in December
      1998,
    
 
   
    - $12.8 million for the Class D Preferred Stock that we sold in December
      1998,
    
 
   
    - $4.8 million for the Class F Preferred Stock that we sold in December
      1998,
    
 
   
    - $4.0 million for the Class G Preferred Stock that we sold in December
      1998,
    
 
   
    - $.9 million for the Senior Preferred Stock that we sold in January 1998
      and
    
 
   
    - the elimination of $.9 million of dividends on the Class B and C Preferred
      Stock that we redeemed in December 1998.
    
 
   
    This does not reflect dividends on the preferred stock issued by Dobson
Tower.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
    
 
OVERVIEW
 
   
    We are a leading provider of rural cellular telephone services. Since we
commenced providing cellular services in 1990 in Oklahoma and the Texas
Panhandle, we have rapidly expanded our cellular operations with an acquisition
strategy targeting underdeveloped rural and suburban areas that have a
significant number of potential customers with substantial needs for cellular
communications. At December 31, 1998, our cellular systems covered a population
of 5.7 million in Arizona, California, Kansas, Maryland, Missouri, New York,
Ohio, Oklahoma, Pennsylvania and Texas.
    
 
    You should read the following discussion and analysis of our historical
financial condition and results of operation in conjunction with our
consolidated financial statements and the related notes that appear elsewhere in
this prospectus.
 
ACQUISITIONS
 
    We continually evaluate opportunities to acquire additional cellular
systems. The following table sets forth the cellular markets and systems we have
acquired since 1995 (ownership in parentheses if we own less than 100%):

    On March 16, 1999 we purchased 13,611 cellular subscribers from the previous
operator of Ohio 2. In conjunction with our acquisition of Texas 10, we are
negotiating with AT&T Wireless for the purchase of subscribers in Texas 10.
 
REVENUE
 
    Our cellular revenues consist of service, roaming and equipment sales
revenues. 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. We believe 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 cellular telecommunications
industry of declining average revenue per subscriber. We believe that the
downward trend results primarily from the the addition of new lower usage
customers who utilize cellular services for personal convenience, security or as
a backup for their traditional landline telephone.
 
   
    Roaming accounted for 29.1%, 39.4% and 47.5% of our cellular revenue for the
years ended December 31, 1996, 1997 and 1998, respectively. While the industry
trend is to reduce roaming rates, we believe that our roaming rates are
generally lower than rates offered by others in or near our system and that such
lower roaming rates mitigate against this trend, however, we cannot assure you
that such trend
    
 
                                       45
<PAGE>
   
will not materially impact us in the future. Our roaming yield (roamer service
revenue, which includes airtime, toll charges and surcharges, divided by roaming
minutes of use) was $.70, $.72 and $.61 per minute (excludes Arizona 5 for 1997,
for which the roaming minutes of use were not available) for the years ended
December 31, 1996, 1997 and 1998.
    
 
    Our overall cellular penetration rates increased in 1998 and 1997 compared
to 1996 due to the incremental penetration gains in existing markets. We believe
that as our cellular penetration rates increase, the increase in new subscriber
revenue will exceed the loss of revenue attributable to the cellular churn rate.
 
    In recent years, we and other cellular providers, have increased the use of
discounts on phone equipment and free phone promotions, as competition between
service providers has intensified. As a result, we have incurred, and expect to
continue to incur, losses on equipment sales, which have resulted in increased
marketing and selling costs per gross additional subscriber. While we expect to
continue these discounts and promotions, we believe that the use of such
promotions will result in increased revenue from increases in the number of
cellular subscribers.
 
COSTS AND EXPENSES
 
    Our primary operating expense categories include cost of service, cost of
equipment, marketing and selling, general and administrative and depreciation
and amortization.
 
    Our cost of service consists primarily of costs to operate and maintain our
facilities utilized in providing service to customers and amounts paid to
third-party cellular providers for providing service to our subscribers.
 
    Our cost of equipment represents the cost associated with telephone
equipment and accessories sold to customers.
 
    Our marketing and selling costs include advertising, compensation paid to
sales personnel and independent agents and all other costs to market and sell
cellular products and services and costs related to customer retention.
Commissions are paid to direct sales personnel for new business generated.
Independent sales agents receive commissions for generating new sales and
ongoing sales to existing customers.
 
    Our general and administrative costs include all infrastructure costs such
as customer support, billing, collections, and corporate administration.
 
   
    The size and scope of our cellular operations increased substantially as as
a result of acquisitions in 1996, 1997 and 1998, and increased further as a
result of our acquisition of Sygnet. See "Pro Forma Condensed Consolidated
Financial Data." Although our cash flow from operations has increased as a
result of acquisitions made to date, the increased amortization and interest
expense and dividends associated with our outstanding senior notes, additional
bank borrowings and Senior Preferred Stock resulted in increased losses in 1997
and 1998. We expect these losses to increase as a result of the Dobson/ Sygnet
notes, our offering of the Preferred Stock and our new credit facilities, and to
continue until we expand our acquired systems and increase our subscriber base.
Our recent acquisitions have affected the comparability of our historical
results of operations for the periods discussed and these results may not be
indicative of future performance.
    
 
DISCONTINUED OPERATIONS
 
    Through our wholly-owned subsidiary, Logix, we provide integrated local,
long distance, data and other telecommunications services to small and
medium-sized business customers throughout the Southwest United States. Logix
operates long-haul fiber optic facilities in Oklahoma, Texas and Colorado. Logix
offers switch-based integrated communications provider services in Oklahoma
City, Tulsa, Amarillo, Houston, Austin, Dallas, Fort Worth and San Antonio.
 
                                       46

    We intend to distribute the stock of Logix to certain of our shareholders in
a tax-free spin-off. The timing of the spin-off is subject to receipt of a
favorable tax ruling or favorable tax opinion acceptable to us and our
shareholders.
 
RESULTS OF OPERATIONS
 
    YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997
 
    OPERATING REVENUE.  For the year ended December 31, 1998, our total
operating revenue increased $73.3 million, or 109.9%, to $140.0 million from
$66.7 million for the comparable period in 1997. Total service, roaming and
equipment revenue represented 49.6%, 47.5% and 2.9%, respectively, of our total
operating revenue during the year ended December 31, 1998 and 57.6%, 39.4% and
2.2%, respectively, of our total operating revenue during the year ended
December 31, 1997.

</TABLE>
 
    Service revenue increased $31.0 million, or 80.7%, to $69.4 million in the
year ended 1998 from $38.4 million in the same period of 1997. Of the increase,
$15.8 million was attributable to acquisitions. The remaining $15.2 million was
primarily attributable to increased penetration and usage in our Central and
Eastern Regions. Our subscriber base increased 251.7% to 352,005 at December 31,
1998 from 100,093 at December 31, 1997. Approximately 220,626 subscribers were
added since December 31, 1997 as a result of acquisitions. Our average monthly
service revenue per subscriber decreased 2.5% to $40 for the year ended December
31, 1998 from $41 for the comparable period in 1997. This decrease resulted from
the addition of new lower rate subscribers in the Eastern Region and competitive
market pressures.
 
    Roaming revenue increased $40.2 million, or 153.1%, to $66.5 million in the
year of 1998 from $26.3 million for the comparable period of 1997. Of the
increase, $25.0 million was attributable to our acquisitions. The remaining
$15.2 million was primarily attributable to increased roaming minutes in our
Central and Eastern Regions due to expanded coverage areas and increased usage
in these markets.
 
    Equipment sales of $4.1 million in the year of 1998 represented an increase
of $2.7 million, or 183.8%, from $1.5 million in the same period of 1997, as we
sold more equipment during the year of 1998 as a result of growth in
subscribers.
 
    COST OF SERVICE.  For the year ended December 31, 1998, our total cost of
service increased $16.8 million, or 102.5%, to $33.3 million from $16.4 million
for the comparable period in 1997. Of the increase, $9.0 million was
attributable to acquisitions. The remaining $7.8 million was primarily
attributable to increased subscribers and minutes of use in our Central and
Eastern Regions and expanded use of rerating agreements with providers adjacent
to our markets. As a percentage of service and roaming revenue, cost of cellular
service remained constant at 24.5% in 1998 compared to 1997.
 
                                       47
<PAGE>
    COST OF EQUIPMENT.  For the year ended December 31, 1998, our cost of
equipment increased $4.3 million, or 106.6%, to $8.4 million during 1998 from
$4.0 million in 1997, primarily from increases in the volume of equipment sold
due to the growth in subscribers.
 
   
    MARKETING AND SELLING COSTS.  Marketing and selling costs increased $11.7
million, or 109.9%, to $22.4 million in 1998 from $10.7 million in 1997. As a
percentage of our total operating revenue, marketing and selling costs remained
constant at 16.0% in 1998 and 1997. We added 66,665 gross subscribers in 1998
and 33,354 gross subscribers in 1997.
    
 
    GENERAL AND ADMINISTRATIVE COSTS.  Our general and administrative costs
increased $14.5 million, or 125.5%, to $26.1 million in 1998 from $11.6 million
for the same period in 1997. As a percentage of our total operating revenue,
general and administrative costs increased to 18.6% in 1998 from 17.3% in the
comparable period of 1997. The increase year over year is a result of our
increased infrastructure costs such as customer service, billing, collections
and administrative costs as a result of overall growth. The increase as a
percentage of total operating revenue resulted from inefficiencies created in
our administrative areas impacted by the fourth quarter operational split of our
wireless and wireline business segments. In addition, we experienced higher than
expected levels of bad debt expenses in certain markets in the fourth quarter.
 
    DEPRECIATION AND AMORTIZATION EXPENSE.  For the year ended December 31,
1998, our depreciation and amortization expense increased $30.3 million, or
180.5% to $47.1 million in 1998 from $16.8 million in 1997. Depreciation and
amortization of assets acquired in acquisitions accounted for $21.1 million of
the increase in 1998 compared to 1997. Our acquisition of Sygnet and California
4 will materially impact depreciation and amortization expense. When giving
effect to our acquisition of Sygnet and related financing, the pro forma
depreciation and amortization expense for 1998 is approximately $121.0 million.
The additional pro forma depreciation and amortization over our historical
depreciation and amortization results primarily from the amortization of
cellular licenses.
 
    INTEREST EXPENSE.  For the year ended December 31, 1998, our interest
expense increased $11.3 million, or 41.0%, to $39.0 million in 1998 from $27.6
million in 1997. The increase resulted primarily from our increased borrowings
in 1998 to finance acquisitions. Our acquisitions of Sygnet and California 4
will materially impact interest expense. When giving effect to these
acquisitions and the related financing, the pro forma interest expense for 1998
is approximately $103.0 million. The additional pro forma interest expense over
our historical interest expense results from the additional debt incurred as a
result of the acquisitions.
 
   
    OTHER INCOME (EXPENSE), NET.  For the year ended December 31, 1998, our
other income increased $1.1 million, or 38.9%, to $3.9 million in 1998 from $2.8
million in 1997. Of the increase, $.9 million was attributable to increased
interest income in 1998. In 1998, we had higher investment balances related to
proceeds from the Senior Preferred Stock and escrow deposits relating to the
Ohio 2 and Sygnet acquisitions.
    
 
    EXTRAORDINARY EXPENSE.  In 1998 and 1997, we incurred an extraordinary
pretax loss of approximately $3.3 million and $2.2 million, respectively, as a
result of writing off previously capitalized financing costs associated with
revolving credit facilities that were refinanced in March 1998 and February
1997.
 
    YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
    OPERATING REVENUE.  For the year ended December 31, 1997, our total
operating revenue increased $39.8 million, or 147.6%, to $66.7 million from
$26.9 million in 1996. Our total service, roaming and equipment revenue
represented 57.6%, 39.4% and 2.2% of our total operating revenue, respectively,
in 1997 and 65.3%, 29.1% and 2.5% of our total operating revenue, respectively,
in 1996.

    Our service revenue increased $20.8 million, or 118.3%, to $38.4 million for
the year ended December 31, 1997 from $17.6 million in 1996. Of the increase,
$15.0 million was attributable to our acquisitions of the Maryland and Arizona
properties in 1997 and the inclusion of the operations of the Kansas/Missouri
properties for all of 1997. The remaining increase resulted primarily from
increased penetration and usage in our Central Region. Our subscriber base
increased 194.8% to 100,093 at December 31, 1997 from 33,955 at December 31,
1996. 42,608 subscribers were added as a result of our acquisitions of the East
Maryland and West Maryland markets. Our average monthly service revenue per
subscriber decreased 15.0% to $41.05 for the year ended December 31, 1997 from
$48.31 for 1996 due to the addition of new lower rate subscribers in the Eastern
Region and competitive market pressures.
    
 
    Our roaming revenue increased $18.4 million, or 234.4%, to $26.3 million for
the year ended December 31, 1997 from $7.9 million in 1996. Of the increase,
$15.6 million was attributable to our acquisitions of the Maryland and Arizona
properties in 1997 and the inclusion of the operations of the Kansas/Missouri
markets for all of 1997. The remaining increase was primarily attributable to
increased roaming minutes in the Central Region due to expanded coverage areas
in these markets and an increase in minutes of use. Equipment sales of $1.5
million in 1997 represented an increase of $0.8 million, or 119.9%, from $0.7
million in 1996, as we sold more equipment in 1997.
 
    COST OF SERVICE.  For the year ended December 31, 1997, our total cost of
service increased $10.3 million, or 168.5%, to $16.4 million from $6.1 million
in 1996. Of the increase, $8.4 million was attributable to our acquisitions of
the Maryland and Arizona properties in 1997 and the inclusion of the operations
of the Kansas/Missouri markets for all of 1997. The remaining increase was
primarily attributable to increased subscribers and minutes of use in the
Central Region and expanded use of rerating agreements with providers adjacent
to the Company's markets. As a percentage of service and roaming revenue, cost
of service increased to 25.4% in 1997 from 24.0% in 1996. This is primarily due
to the expanded use of rerating agreements noted above, as well as additional
facility lease costs in East Maryland.
 
    COST OF EQUIPMENT.  For the year ended December 31, 1997, our total cost of
equipment increased $1.4 million, or 57.3% to $4.0 million from $2.6 million in
1996, primarily from increases in the volume of equipment we sold due to the
growth in subscribers.
 
    MARKETING AND SELLING COSTS.  Our marketing and selling costs increased $6.2
million, or 139.1%, to $10.7 million in 1997 from $4.5 million in 1996. The
increase was primarily due to the higher level of subscribers added period to
period. We added 33,354 gross subscribers in 1997 with subscribers added in our
Eastern Region and in Arizona 5 since their acquisitions making up 16,469 and
1,307, respectively, of the gross subscribers added. We added 11,970 gross
subscribers in 1996. As a percentage of our total operating revenue, marketing
and selling costs decreased to 16.0% in 1997 from 16.6% in 1996.
 
    GENERAL AND ADMINISTRATIVE COSTS.  For the year ended December 31, 1997, our
general and administrative costs increased $7.7 million, or 196.2%, to $11.6
million from $3.9 million for the same period of 1996.
 
                                       49
<PAGE>
   
The increase was primarily due to our increased billing costs as a result of the
growth in wireless subscribers, the 1997 Acquisitions, the inclusion of our
Kansas/Missouri markets for all of 1997, and increased salary costs resulting
from additional personnel. As a percentage of total operating revenue, general
and administrative costs increased from 14.5% in 1996 to 17.3% in 1997. This
increase resulted from the addition of personnel necessary to support expanded
operations.
    
 
   
    DEPRECIATION AND AMORTIZATION EXPENSE.  For the year ended December 31,
1997, our depreciation and amortization expense increased $11.6 million, or
220.5%, to $16.8 million from $5.2 million in 1996. There was a $12.1 million
increase that resulted from the amortization of assets acquired in our
acquisitions of the Maryland and Arizona properties in 1997 and the
Kansas/Missouri Acquisition in 1996 offset by a slight decrease related to
assets in the Central Region.
    
 
   
    INTEREST EXPENSE.  For the year ended December 31, 1997, interest expense
increased $23.3 million to $27.6 million from $4.3 million in 1996. The increase
resulted primarily from our increased borrowings to finance the acquisitions of
the Maryland and Arizona properties.
    
 
   
    OTHER INCOME (EXPENSE), NET.  For the year ended December 31, 1997, our
total other income expense (net) (consisting of interest income, and other
income/expense) increased $4.3 million to $2.8 million from $(1.5) million in
1996. The increase resulted primarily from interest earned on securities we
purchased and pledged to secure payment of the first four semi-annual interest
payments on the Senior Notes.
    
 
    EXTRAORDINARY EXPENSE.  In 1997 and 1996, we incurred an extraordinary
pretax loss of approximately $2.2 million and $0.9 million, respectively, as a
result of writing off previously capitalized financing costs associated with a
revolving credit facility that we refinanced in February 1997 and March 1996.
 
IMPACT OF YEAR 2000 ISSUE
 
    The Year 2000 issue exists because many computer systems and applications,
including those embedded in equipment and facilities, use two digit rather than
four digit date fields to designate an applicable year. As a result, the systems
and applications may not properly recognize the year 2000 or process data that
includes it, potentially causing data miscalculations, inaccuracies, operational
malfunctions or failures.
 
    In April 1998, we established a multi-disciplined team to perform a Year
2000 impact analysis. The team consists of representatives from each of the
lines of business, as well as representatives from key corporate departments,
and is headed by a full-time Year 2000 compliance manager. The team created a
Year 2000 assessment methodology which brought a structured approach to the
assessment and management reporting process, as well as disaster recovery
approach.
 
   
    To date, we have completed an inventory of our automated systems and
services and an impact analysis that identified significant risk areas by line
of business, specific compliance requirements and costs and estimated completion
dates for affected systems. The services we provide are based on the systems of
RBOCs and other systems outside our control. We have been in contact with all of
the vendors of products and services that we believe are critical to our
operations. The representation from our vendors pertaining to Year 2000
compliance has come in writing directly to us, in contracts, and by accessing
Year 2000 information available at their Web sites. While all of the vendors
have provided some type of assurance that their products will be Year 2000
compliant, not all have provided us expressly with a "Year 2000 Compliance
Statement" and/or a "Year 2000 Warranty." Our focus with our vendors has been
directed toward what assurances of Year 2000 compliance they can provide in the
form of documented Year 2000 planning and testing and third party audits.
    
 
   
    We do not have large scale legacy applications used by many
telecommunications providers. From an information systems standpoint, we have
historically relied on outsourcing relationships for most of our business and
operational support applications. Those applications that have not been
outsourced to service providers have been deployed using packaged software from
outside vendors. As a result, the remediation
    
 
                                       50
<PAGE>
phase is not focused on a large scale in-house effort, but on identification of
third party systems and services that are not currently Year 2000 compliant and
oversight of third party compliance efforts.
 
    The results of the impact analysis revealed that for most of our information
systems, services and telecommunications infrastructure, Year 2000 compliant
versions will be included as a part of existing maintenance and/or service
agreements at no additional cost to us and should be in place and tested by the
second quarter of 1999. However, there are two critical systems that will not be
replaced until third quarter 1999. Those systems are one Ericsson cellular
switching system in New York and portions of our ITDS billing system,
principally in the Eastern Region. The Ericsson switching equipment will be
replaced with Year 2000 compliant Nortel equipment. We expect to complete this
replacement in the third quarter of 1999. In the first quarter of 1999, we
decided to replace our current billing system vendor, ITDS, with a new vendor,
H.O. Systems, which is Year 2000 compliant. The H.O. Systems software is in
place and functioning in our Western Region markets. We are in the process of
implementing the H.O. Systems software throughout our other markets and expect
to complete the implementation in the third quarter of 1999. We estimate total
costs of approximately $.75 million to upgrade or replace those systems that are
not Year 2000 compliant and will not be upgraded through existing maintenance or
service agreements. The estimated costs for Year 2000 compliance do not include
the costs of upgrading our New York system or replacing the billing vendor, as
those decisions were made for business reasons outside of the Year 2000 issue
and would have been made regardless of whether the systems currently in place
were Year 2000 compliant. All of our automated systems and services are or will
be Year 2000 compliant by the end of the third quarter of 1999.
 
    Our contingency planning is being addressed in two parts. First, in the
event that a product or service is not compliant by the end of the second
quarter of 1999, where feasible, we have identified alternate compliant products
or services that can replace them. Second, possible disruptions to operations
after the rollover to the Year 2000 are being addressed as a part of our overall
disaster recovery plan, which will be completed by the end of 1999.
 
    We will continue to analyze systems and services that utilize date-embedded
codes that may experience operational problems when the Year 2000 is reached. We
will continue communicating with third party vendors of systems software and
equipment, suppliers of telecommunications capacity and equipment, roaming
partners customers and others with which it does business to coordinate Year
2000 compliance. To further mitigate risks, if a critical vendor does not
provide adequate assurance that its product is Year 2000 compliant through test
plans, test results or third party audit results, we will either replace the
product with one that has provided proof of compliance or will conduct our own
Year 2000 tests.
 
   
    In the event any of our vendors has represented that it is Year 2000
compliant and, in fact, it is not, we would have no recourse against this vendor
other than an action for damages for either breach of contract or, in the
absence of a contractual obligation, for negligence if we could establish that
the vendor had a legal duty to us to be Year 2000 compliant. If we are unable to
provide systems and services to our customers, because either our own systems or
those of our vendors are not Year 2000 compliant, our reasonably likely worst
case scenario is that we would experience a reduction in our operating revenues
which could adversely affect our ability to meet our operating and financial
obligations.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
    We are a holding company with no direct operations and no significant assets
other than the stock of our subsidiaries. We depend on the cash flows of our
subsidiaries to meet our obligations, including our obligations to pay interest
and principal on our indebtedness, and dividends on the Senior Preferred Stock
and Preferred Stock. Our subsidiaries are separate legal entities that have no
obligation to pay any amounts owed by us or to make any funds available to us.
The ability of our subsidiaries to distribute funds
 
                                       51
<PAGE>
to us are and will be restricted by the terms of existing and future
indebtedness including our credit facilities. See "Risk Factors--We are
dependent on cash flows from our subsidiaries."
 
    Our cellular operations require substantial capital to acquire, construct
and expand wireless telephone systems and to fund operating requirements. We
have financed our operations through bank debt and the sale of debt and equity.
 
    At December 31, 1998, we had working capital of $13.5 million (a ratio of
current assets to current liabilities of 1.1:1) and an unrestricted cash balance
of $22.3 million. At December 31, 1997, we had working capital of $15.9 million
(a ratio of current assets to current liabilities of 1.7:1) and an unrestricted
cash balance of $2.8 million, which compares to working capital of $10.6 million
(a ratio of current assets to current liabilities of 2.9:1) and an unrestricted
cash balance of $1.0 million at December 31, 1996.
 
    Our net cash provided by operating activities totaled $28.0 million for 1998
compared to $6.9 million for 1997 and $5.2 for 1996. The increase of $1.7
million from 1996 to 1997 was primarily due to net changes in current assets and
liabilities, depreciation and amortization and deferred income taxes, offset by
our net loss for the period. The increase of $21.1 million from 1997 to 1998 was
primarily due to depreciation and amortization and the change in current assets
and liabilities offset by our net loss for the period.
 
    Net cash used in investing activities, which totaled $43.9 million, $217.6
million and $999.1 million for the years ended December 31, 1996, 1997 and 1998,
respectively, principally related to acquisitions and capital expenditures in
all periods. Acquisitions accounted for $30.0 million, $190.7 million and $945.4
million in 1996, 1997 and 1998, respectively, and capital expenditures were
$13.5 million, $17.8 million and $55.3 million in 1996, 1997 and 1998,
respectively.
 
   
    Net cash provided by financing activities was $990.6 million for 1998
compared to $212.5 million for 1997 and $38.9 million for 1996, respectively.
Financing activity sources for the year ended December 31, 1998 consisted
primarily of $740.0 million of proceeds from bank borrowings, the issuance of
$200.0 million of Dobson/Sygnet Notes, the issuance of $225.0 million of Senior
Preferred Stock, net and the issuance of $115.0 million of other preferred
stock. These activities were offset by financing activity uses, including the
purchase of $67.7 million of restricted investments to be used to fund the first
six semi-annual interest payments on the Dobson/Sygnet Notes and $62.0 million
of deferred financing costs relating to the new credit facilities and financing
our acquisition of Sygnet. Proceeds from long-term debt exceeded repayment
thereof by $39.4 million, $256.3 million and $768.5 million in 1996, 1997, and
1998, respectively.
    
 
    In April 1997, we entered into an interest rate hedge agreement terminating
on April 24, 2002 to hedge our interest expense on $160.0 million of
indebtedness under its revolving credit facilities. In 1998, the counterparty
exercised its rights under the swap agreement, fixing the interest rate at 6.13%
plus a factor used on our leverage. We account for this as a hedge. Subsequent
to December 31, 1998, we entered into an interest rate swap that effectively
fixed the interest rate on $110.0 million of the principal outstanding on the
Dobson/Sygnet Credit Facilities at 8.9%. The term of this interest rate swap is
24 months.
 
    The minority partners in our partnerships that own certain of our cellular
operations receive distributions equal to their share of the profit multiplied
by estimated income tax rates. Under our bank credit agreements, our minority
partners are not entitled to receive any cash distributions in excess of amounts
required to meet income tax obligations until all indebtedness of their
respective partnerships to us is paid or extinguished.
 
    Our capital expenditures (excluding cost of acquisitions and discontinued
operations) were $55.3 million for the year ended December 31, 1998 and we
expect our capital expenditures (excluding cost of acquisitions) to be
approximately $45 million to $50 million for 1999. We have not budgeted any
amounts to be expended in 1999 with respect to the systems which may be acquired
in other acquisitions or our PCS system. The amount and timing of capital
expenditures may vary depending on the rate at which we expand and develop our
cellular systems and whether we consummate additional acquisitions.
 
                                       52
<PAGE>
    On December 23, 1998, our subsidiary acquired all of the outstanding capital
stock of Sygnet for $337.5 million. The Sygnet Acquisition was financed through
borrowings under the Dobson/Sygnet Credit Facilities, the net proceeds of
offering the Additional Preferred Stock, the Equity Investments and the Tower
Sale Leaseback ("Sygnet Financing").
 
    We have agreed to purchase approximately $65 million of cell site and
switching equipment between June 1997 and November 2001. Of this commitment,
approximately $32.3 million remained at December 31, 1998. Under another
equipment supply agreement, we agreed to purchase approximately $81.0 million of
cell site and switching equipment by January 13, 2002. Of this commitment, $58.4
million remained at December 31, 1998.
 
    In April 1997, we were granted PCS licenses in nine markets in Oklahoma,
Kansas and Missouri. We financed $4.1 million of the $5.1 million purchase price
with government loans secured by liens on the PCS licenses at an annual interest
rate of 6.25%, amortizing quarterly over eight years beginning in 1999. We are
required to build out systems covering 25% of the population covered by each of
the PCS licenses by 2002. We currently anticipate that the cost to build out the
minimum PCS system will be $10.0 million to $30.0 million. The actual amount of
the expenditures will depend on the PCS technology we select, the extent of our
buildout, the costs at the time of buildout and the extent we must bear the
expense of relocating incumbent microwave licensees, as mandated by FCC rules.
We have not budgeted any amounts for capital expenditures in 1999 with respect
to the buildout of a PCS system.
 
    In March 1998, our subsidiary, Dobson Cellular Operations Company ("DCOC"),
established a $200.0 million senior secured credit facility (the "DCOC Credit
Facility"). Under the terms of the DCOC Credit Facility, an additional $75.0
million revolving credit facility may be established for acquisitions. This
uncommitted facility requires that we have borrowings outstanding of at least
two-thirds of the committed amount under the DCOC Credit Facility. DCOC's
obligations under the DCOC Credit Facility are secured by all existing and
future assets of DCOC, and are guaranteed by DCOC's subsidiaries. In addition,
our subsidiary, Dobson Operating Company ("DOC"), established a $250.0 million
senior secured credit facility (the "DOC Credit Facility") to replace a prior
bank facility. The DOC Credit Facility is secured by all of DOC's stock and the
stock or partnership interests of its subsidiaries and all assets of DOC and its
restricted subsidiaries. We and DOC's subsidiaries, other than Logix and the
Arizona 5 Partnership, have guaranteed DOC's obligations under the DOC Credit
Facility. The DCOC Credit Facility and the DOC Credit Facility requires us to
maintain certain financial ratios. The failure to maintain such ratios would
constitute an event of default, notwithstanding our ability to meet its debt
service obligations. To date, we have met the required financial ratios. The DOC
Credit Facility and DCOC Credit Facility each amortize quarterly beginning June
30, 2000 and terminate on June 30, 2006. At December 31, 1998, we had credit
available of $117.0 million under the DOC Credit Facility, subject to covenant
limitations and no availability under the DCOC Credit Facility. We expect to
borrow $9.1 million under the DOC Credit Facility to close the Maryland 1
Acquisition and $6.0 million under the Dobson/Sygnet Credit Facilities to close
the Pennsylvania 2 Acquisition.
 
    Dobson/Sygnet is a party to a credit agreement with NationsBank for an
aggregate $430.0 million, consisting of a $50.0 million revolving credit
facility and $380.0 million of term loan facilities. As of December 31, 1998, we
had $407.0 million outstanding under the Dobson/Sygnet Credit Facilities at a
weighted average interest rate of 8.9%. No principal amounts are due under the
facilities until 1999. The obligations under the Dobson/Sygnet Credit Facilities
are secured by a pledge of the capital stock of Dobson/Sygnet's operating
subsidiary as well as a lien on substantially all of the assets of Dobson/Sygnet
and its operating subsidiary. The Dobson/Sygnet Credit Facilities require
Dobson/Sygnet and us to maintain certain financial ratios. The failure to
maintain such ratios would constitute an event of default, notwithstanding
Dobson/Sygnet's ability to meet its debt service obligations. To date, we
believe we have maintained all required ratios. The ability of Dobson/Sygnet to
borrow under the Dobson/Sygnet Credit Facilities will be limited by the
requirement that, on a quarterly basis beginning December 31, 2000, the
 
                                       53
<PAGE>
amount available under the Dobson/Sygnet Credit Facilities will reduce until
they terminate. At December 31, 1998, the Company had credit available of $23.0
million under the Dobson/Sygnet Credit Facilities, subject to covenant
limitations.
 
    The Dobson/Sygnet Notes bear interest at an annual rate of 12.25% and mature
in 2008. Of the net proceeds, $67.7 were used to purchase securities pledged to
secure the first six semi-annual interest payments, which begin June 15, 1999.
 
    As part of our acquisition of Sygnet and the related financing, Sygnet sold
to Dobson Tower, a wholly owned subsidiary of the Company, substantially all of
the towers it owned for $25.0 million. Dobson Tower then leased these towers
back to Sygnet under an operating lease, with net annual lease payments of
approximately $1.4 million. Dobson Tower obtained the funds for such purchase
from borrowings under a new credit facility of $17.5 million and the sale of
$7.7 million of preferred stock of Dobson Tower to our affiliate.
 
    Through Sygnet, we are a party to an agreement to purchase the FCC license
for, and certain assets related to, Pennsylvania 2 RSA for $6.0 million (the
"Pennsylvania 2 Acquisition"). Because the seller's title to the license remains
subject to administrative and judicial review, the closing of such acquisition
has been delayed. Pending such closing, Dobson/Sygnet is managing the operation
of the cellular system in the market under the supervision and control of the
seller. Recently we entered into an agreement for the purchase of the FCC
license for, and certain assets related to, Maryland 1 RSA and an unserved
portion of Cumberland, Maryland MSA for $9.1 million in cash (the "Maryland 1
Acquisition"), subject to adjustment. We have no agreements with respect to any
acquisitions other than the Pennsylvania 2 Acquisition and the Maryland 1
Acquisition.
 
    Although we cannot provide any assurance, we believe that, assuming
successful implementation of our strategy, including the further development of
our cellular systems and significant and sustained growth in our cash flow,
borrowings under the Dobson/Sygnet Credit Facilities, the DOC Credit Facility,
the Tower Sale Leaseback, the DCOC Credit Facility and cash flow from
operations, will be sufficient to consummate the Maryland 1 Acquisition and the
Pennsylvania 2 Acquisition and are expected to be sufficient to satisfy our
currently expected capital expenditure, working capital and debt service
obligations. However, we will need to refinance the Dobson/Sygnet Credit
Facilities, the DOC Credit Facility, the DCOC Credit Facility, the DCC Senior
Notes and the Dobson/Sygnet Notes at their maturities and refinance our
mandatory redemption obligations with respect to our preferred stock, including
the Additional Preferred Stock and Senior Exchangeable Preferred Stock. Our
ability to do so will depend on, among other things, our financial condition at
the time, the restrictions in the instruments governing our indebtedness and
other factors, including market conditions beyond our control. The actual amount
and timing of our future capital requirements may differ materially from our
estimates as a result of, among other things, the demand for our services and
regulatory, technological and competitive developments. Sources of additional
financing may include commercial bank borrowings, vendor financing and the sale
of equity or debt securities. We cannot assure you that any such financing will
be available on acceptable terms or at all.
 
EFFECT OF NEW ACCOUNTING STANDARDS
 
    In July 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Derivatives and Hedging ("SFAS 133").
SFAS 133 establishes uniform hedge accounting criteria for all derivatives
requiring companies to formally document, designate and assess the effectiveness
of transactions that receive hedge accounting. Under SFAS 133, derivatives will
be recorded in the balance sheet as either an asset or liability measured at its
fair value, with changes in the fair value recognized in current earnings. SFAS
133 will be effective for fiscal years beginning after June 15, 1999. Under SFAS
133, we would record a liability of $5.4 million relating to an interest rate
hedge valuation at December 31, 1998. We have not determined the timing or
method of adoption of SFAS 133.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
    
 
   
    Our primary market risk relates to changes in interest rates. Market risk is
the potential loss arising from adverse changes in market prices and rates,
including interest rates. The objective of our financial risk management is to
minimize the negative impact of interest rate fluctuations on our earnings and
equity. During 1998, we had an interest rate hedge on $160.0 million of our
outstanding indebtedness under the DOC Credit Facility. The hedge counterparty
is a major financial institution. Losses on the interest rate hedge in 1998 were
reflected in income and were immaterial. We did not recognize any gains or
losses in 1997 or 1996 from such interest rate hedging. We do not enter into
derivatives or other financial instruments for trading or speculative purposes.
    
 
   
    The fair market value of long-term fixed interest rate debt is subject to
interest rate risk. Generally, the fair market value of fixed interest rate debt
will increase as interest rates fall and decrease as interest rates rise. The
estimated fair values of our total long-term fixed rate and our variable-rate
debt are shown in Note 15 to our consolidated financial statements. Based on our
market risk sensitive instruments outstanding at December 31, 1998, we have
determined that there was no material market risk exposure to our consolidated
financial position, results of operations or cash flows as of such date.
    
 
                                       55

                                    BUSINESS
    
 
   
    We are a leading provider of rural and suburban cellular telephone services.
Since we began providing cellular service in 1990 in Oklahoma and the Texas
Panhandle, we have rapidly expanded our cellular operations with an acquisition
strategy targeting rural and suburban areas which have a significant number of
potential customers with substantial needs for cellular communications. At
December 31, 1998, our cellular systems covered a population of 5.7 million in
Arizona, California, Kansas, Maryland, Missouri, New York, Ohio, Oklahoma,
Pennsylvania and Texas.
    
 
    We believe that our mix of rural and suburban cellular systems generally
provides strong growth opportunities due to lower penetration rates, higher
subscriber growth rates and a higher proportion of roaming revenue compared to
cellular systems located in larger MSAs. We focus on systems that are adjacent
to major metropolitan areas and include a high concentration of expressway
corridors that tend to have a significant amount of roaming activity. We believe
these areas are not as fully developed as large MSAs, which were licensed
earlier by the FCC, and have the potential for increased cellular usage and
superior financial performance. We have entered into roaming agreements with
operators of cellular systems in neighboring MSAs and RSAs and other MSAs and
RSAs that allow customers to roam at competitive prices that, in certain
instances, are comparable to our home area rates.
 
    We seek to establish and maintain a strong and visible local presence while
achieving economies of scale and synergies through centralization of certain
functions. Our local management teams 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. In addition, we believe
that our marketing and customer service functions are more effective when
tailored to the local market population. The regional presence of our call
centers enhances our knowledge of local markets, which improves our ability to
provide customer service, credit and collection and order activation. However,
we retain centralized control of marketing, pricing, system design, engineering,
purchasing, financial and administrative functions to maximize operating
leverage and continuity over our cellular systems.
 
   
    We have developed organizational, marketing and operational programs
designed to increase the number and retention of subscribers, promote superior
customer service, control subscriber acquisition costs and enhance operating
cash flow. We intend to apply these programs to the properties we acquire. We
recently closed into escrow our acquisitions of the FCC licenses for, and
certain assets related to, Texas 10 RSA for $55.0 million in cash, and Ohio 2
RSA for $39.3 million in cash. In addition, we recently entered into an
agreement for the purchase of the FCC licenses for, and certain assets related
to, Maryland 1 RSA for $9.1 million in cash, subject to adjustment.
    
 
STRATEGY
 
    Our business strategy is to focus on the development and acquisition of
rural and suburban cellular systems. The principal elements of our strategy
include:
 
   
    - INTEGRATE ACQUIRED OPERATIONS. We intend to integrate the operations of
      systems we acquire with our 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.
      We expect to consolidate Sygnet's three call service centers and one of
      our call centers. We intend to use our increased leverage in negotiating
      prices and services from third party service providers and equipment
      vendors.
    
 
    - EXPAND STRATEGIC RELATIONSHIPS. We intend to continue to maintain and
      expand strategic relationships with operators of cellular systems in major
      MSAs near our systems. These relationships include
 
                                       56
<PAGE>
   
      roaming agreements which allow our subscribers to use the system in the
      neighboring MSA at favorable rates. Under these agreements, similar
      benefits are available to the MSA operator's subscribers roaming in our
      areas. In addition, we will deploy digital technology in its system area
      which is the same as that selected by our roaming partner in the
      neighboring MSA. We also market our cellular products and services under
      the predominant brand name in the neighboring MSA. These brand names
      include CELLULAR ONE-Registered Trademark- and AIRTOUCH-SM- CELLULAR.
      These strategic relationships and agreements enable us to increase our
      roaming revenue, offer its subscribers larger home rate areas and leverage
      the recognized brand names of its roaming partners and their extensive
      marketing efforts. See "Risk Factors--We depend on third party service
      marks to market our products area services. The loss of the right to use
      the service marks could adversely affect our business."
    
 
   
    - AGGRESSIVE LOCAL MARKETING AND PROMOTION OF CELLULAR SERVICES. Our
      marketing objective is to continue to distinguish ourself as the local
      market's leading cellular services provider, stressing our service
      quality, local sales offices and commitment to the community. Our sales
      efforts are conducted primarily through our retail outlets and our direct
      sales force and, to a lesser extent, through independent agents.
    
 
    - TARGETED SALES EFFORTS. We seek to attract subscribers who are likely to
      generate high monthly revenue and low churn rates. Local management
      conducts 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 our cellular
      service.
 
    - SUPERIOR CUSTOMER SERVICE. We intend to maintain a high level of customer
      satisfaction through a variety of techniques, including maintaining
      24-hour customer service. We support local customer service through our
      direct sales force and our retail stores, and through regional customer
      service centers.
 
    - CONTINUED SYSTEM DEVELOPMENT. We believe that increasing capacity and
      upgrading our systems will attract additional subscribers, enhance the use
      of our systems by existing subscribers, increase roaming activity and
      further enhance the overall efficiency of the network. We intend to
      continue to upgrade our systems with digital technology to enable us 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.
 
   
    - DISCIPLINED EXPANSION THROUGH ACQUISITIONS. We continually evaluate
      opportunities to acquire additional rural and suburban cellular systems.
      In evaluating acquisitions, we target RSAs and small MSAs that have some
      or all of the following characteristics in addition to others:
    
 
           - are adjacent to major metropolitan areas;
 
           - have positive population growth trends;
 
           - include a high concentration of expressway corridors that have a
             significant amount of roaming activity; and
 
           - have the potential to develop strategic relationships with
             operators of neighboring wireless systems and the ability to offer
             service under a leading brand name.
 
We currently have two pending acquisitions. Sygnet is party to an agreement to
purchase the FCC license for, and certain assets related to, Pennsylvania 2 RSA
for $6.0 million. Because the seller's title to the license remains subject to
administrative and judicial review, the closing of such acquisition has been
delayed. Pending such closing, Sygnet is managing the operation of the cellular
system in the market under the supervision and control of the seller. In
addition, we recently entered into an agreement to purchase
 
                                       57
<PAGE>
the FCC license for, and certain assets related to, Maryland 1 RSA and the
unserved portion of Cumberland, Maryland MSA for $9.1 million, subject to
adjustment. We have no agreements with respect to any acquisitions other the
acquisitions of Maryland 1 RSA and the Pennsylvania 2 RSA.
 
DISCONTINUED OPERATIONS
 
    Through our wholly owned subsidiary, Logix, we provide integrated local,
long distance, data and other telecommunications services and long-haul fiber
optic services to business customers in the Southwest United States.
 
   
    We have designated Logix an unrestricted subsidiary with the result that
Logix is not be subject to certain covenant and similar restrictions which apply
to the rest of our operations. We intend to distribute the stock of Logix to
certain of our shareholders, subject to receipt of a favorable tax ruling from
the Internal Revenue Service or a favorable tax opinion acceptable to us and our
shareholders and subject to the receipt of consents from a majority of the
principal amount of our outstanding 11 3/4% Senior Notes due 2007. Holders of
our Preferred Stock will not participate in our distribution of Logix stock.
Logix is accounted for as a discontinued operation in our consolidated financial
statements.
    
 
   
RECENT EVENTS
    
 
   
    On December 23, 1998, our subsidiary, Dobson/Sygnet Communications Company,
acquired Sygnet for $337.5 million in cash.
    
 
   
    Effective January 16, 1999, we amended our operating agreement with AT&T
Wireless to modify the roaming airtime rates we will charge each other through
June 30, 2004. We believe the new rates will increase the total airtime used by
our customers which will increase our gross revenues.
    
 
   
    Effective April 13, 1999, AT&T Wireless entered into an agreement to
purchase certain shares of our Class D Preferred Stock and common stock from one
of our existing shareholders for $20.0 million. AT&T Wireless' purchase is
subject to compliance with Hart-Scott-Rodino Act and other customary closing
conditions. Following the consummation of it stock purchase, AT&T Wireless will

    Our first quarter total operating revenues were approximately $68 million.
Our first quarter results do not include any operating revenue from the Ohio 2
RSA and Texas 10 RSA. Our subscriber count at March 31, 1999 was approximately
381,000, including 13,611 subscribers in Ohio 2 RSA that we purchased late in
the first quarter. This is an increase from 352,000 subscribers at December 31,
1998. Net subscriber additions for the quarter, not including subscribers
purchased in Ohio 2 RSA, were approximately 16,000.
    
 
   
    On May 5, 1999, we expect to conclude a private offering of $170.0 million
of another class of our preferred stock. We will use the net proceeds of that
offering to redeem all outstanding shares of our Class F Preferred Stock and
Class G Preferred Stock, to reduce our bank debt and for general corporate
purposes.
    
 
MARKETS AND SYSTEMS
 
    The following table sets forth certain data as of December 31, 1998 with
respect to our existing cellular markets. We determine our market penetration by
dividing total subscribers by the total population covered by the applicable FCC
cellular license or authorizations that we or our subsidiaries hold. We recently
closed into escrow our acquisitions of the FCC licenses for, and certain assets
related to, Texas 10 RSA for $55.0 million and Ohio 2 RSA for $39.3 million. The
previous operator of Texas 10 RSA estimates the number of subscribers at 1,400.
On March 16, 1999, we purchased 13,611 subscribers in Ohio 2 RSA from the
previous operator. We are negotiating to purchase the subscribers in Texas 10
RSA.

    OHIO 2
 
    GENERAL.  On September 2, 1998, we purchased the FCC license for, and
related assets of, Ohio 2 RSA for $39.3 million, subject to resolutions of
certain matters regarding the seller's title to the FCC licenses. Ohio 2 is
located in north-central Ohio bordered by Lake Erie on the north and Cleveland
on the east, and includes a population of 262,100. On March 16, 1999, we
purchased 13,611 subscribers and certain assets in Ohio 2 from AirTouch for $3.9
million. We expect to assume all operations of Ohio 2 in the second quarter of
1999. Until then, AirTouch will provide certain services to us that are
necessary to operate the system.
 
   
    DEMOGRAPHICS.  Ohio 2 covers an area of approximately 1,700 square miles in
north central Ohio in which the principal industries are manufacturing and
agriculture. The Ohio 2 market includes 54 miles of I-80, linking Sandusky to
Toledo, Akron, and Cleveland, 56 miles of US-224 and 35 miles of State Highway

CELLULAR OPERATIONS
 
    PRODUCTS AND SERVICES
 
    We provide a variety of cellular services and products designed to address a
range of consumer, business and personal needs. In addition to mobile voice and
data transmission, we offer 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 we offer varies depending upon
the market area. We
 
                                       65
<PAGE>
also sell cellular equipment at discount prices and uses free phone promotions
as a way to encourage use of its mobile services. We offer cellular service for
a fixed monthly access fee (accompanied by varying allotments of unbilled or
"free" minutes), plus additional variable charges per minute of use and for
custom calling features. Various pricing programs (which include single year
and, to a lesser extent, multi-year service contracts) are utilized. Unlike some
of our competitors, we design rate plans on a market-by-market basis. Our local
general managers generally have the authority to initiate and modify rate plans,
depending upon market and competitive conditions. Generally, these rate plans
include a high-volume user plan, a medium-volume user plan, a basic plan and an
economy plan. In general, our rate plans which include a higher monthly access
fee typically include a lower usage rate per minute. We maintain an ongoing
review of equipment and service plan pricing and, as appropriate, we revise
pricing to meet the demands of the local marketplace.
 
    CUSTOMER SERVICE
 
    Customer service is an essential element of our marketing and operating
philosophies. We are committed to attracting new subscribers and retaining
existing subscribers by providing consistently high-quality customer service. In
each of our cellular service areas, we maintain installation and repair
facilities and a local staff, including a market manager, customer service
representatives, technical and sales representatives. In each of our cellular
service areas, we handle our own customer-related functions such as customer
activations, account adjustments and rate plan changes. Our local offices and
installation and repair facilities enable us to service customers better,
schedule installations and make repairs. Through the use of sophisticated,
centralized monitoring equipment, we are able to centrally monitor the technical
performance of its cellular service areas.
 
    In addition, our customers generally are able to report cellular telephone
service or account problems 24-hours a day to our regional customer service
centers located in Oklahoma City, OK and Frederick, MD on a toll-free access
number with no airtime charge. We believe that our emphasis on customer service
affords us a competitive advantage over our large competitors. We contact our
subscribers at frequent intervals in order to evaluate and measure, on an
ongoing basis, the quality and competitiveness of our services.
 
    SALES, MARKETING AND DISTRIBUTION
 
    We focus our marketing program on attracting subscribers who are likely to
generate high monthly revenue and low churn rates. We 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 our cellular service. We have established marketing
alliances with neighboring cellular systems to create larger home rate areas and
to effectively expand our home rate area in order to increase our roaming
revenue and to attract new subscribers. We market our service offerings
primarily through our direct sales force and Company-owned retail stores. We
also use a network of dealers and other agents, such as electronics stores, car
dealerships and department stores. In addition to these traditional channels,
our marketing team continuously evaluates other, less traditional, methods of
distributing the Company's services and products, such as targeted telemarketing
and direct mail programs.
 
    We market our cellular products and services under both national brand names
and our own brand name. See "--Service Marks." The service mark we select for
use in each of our markets depends, to a large extent, upon the service mark
used in neighboring MSAs. We market our cellular products and services under the
name Dobson Cellular-TM- in portions of Oklahoma 5 and 7 and the Texas
Panhandle. In its Northwest Oklahoma, Kansas and Missouri, Central Texas and
Eastern Region markets, we market our cellular service under the name 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 our advertising exposure at a fraction of the cost of what
could be achieved by us alone. We use the service mark AIRTOUCH-TM- CELLULAR in
our southern California and Arizona properties and in our Ohio 2
 
                                       66
<PAGE>
market, and expect to use a national brand name in central Texas and the name
CELLULAR ONE-Registered Trademark- in northern California. In our Northern
Region, we expect to continue Sygnet's use of the CELLULAR
ONE-Registered Trademark- brand name in all of Sygnet's areas other than the
Youngstown and Sharon MSAs in which the name Wilcom Cellular will continue to be
utilized. See "--Service Marks."
 
    We train and compensate our sales force in a manner designed to stress the
importance of customer service, high penetration levels and minimum acquisition
costs per subscriber. We believe that our 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, we
motivate our direct sales force to sell appropriate rate plans to subscribers,
thereby reducing churn, by linking payment of commissions to subscriber
retention. As a result, our 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. We
currently have 97 direct sales agents.
 
    We believe that the after-sale telemarketing program conducted by our sales
force and customer service personnel helps to reduce our churn rate. This
program enhances customer loyalty and allows our sales staff to check customer
satisfaction as well as to offer additional calling features, such as voicemail,
call waiting and call forwarding.
 
    We operated 67 retail outlets as of December 31, 1998. Our retail stores
range in size from 420 square feet to 6,400 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.
Our 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.
 
    ROAMING
 
    We believe that regional roaming is an important service component for many
subscribers. Accordingly, where possible, we attempt to arrange reciprocal
roaming agreements that allow customers to roam at competitive prices. We
believe this increases usage on all cellular systems, including our own. Roaming
is a substantial source of our revenue. We focus on systems that are adjacent to
major metropolitan areas and include a high concentration of expressway
corridors that tend to result in a significant amount of roaming activity. We
have entered into roaming agreements with operators of cellular systems in
adjoining MSAs and others which provide for reciprocal roaming rates that allow
area customers to roam at competitive
 
                                       67
<PAGE>
prices which, in certain instances, are comparable to their home area rates. The
following table lists our principal roaming partners in each of our cellular
markets:

    We have 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.
 
    PCS
 
    In April 1997, we were granted PCS licenses in nine markets in Oklahoma,
Kansas and Missouri that are adjacent to or overlap the Company's existing
cellular markets. The PCS licenses obligate us to construct network facilities
that cover at least 25% of the population in each market within five years from
the grant of the license. The licenses cover an aggregate of approximately 4.2
million total Pops. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
    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
 
                                       68
<PAGE>
single number (or "find me") service, and more complex data transmission
features, such as "mobile office" applications (including facsimile, electronic
mail and connecting notebook computers with computer/data networks).
 
    While digital technology generally serves 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 developed by vendors for digital cellular
systems became available in late 1997. These new handsets offer transmission
quality comparable to current analog cellular handsets.
 
    SYSTEM DEVELOPMENT.  We develop or build out our 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 capacity and to improve coverage for
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. Historically we have met such demand through a combination of augmenting
channel capacity in existing cell sites and building new cell sites. In January
1998, we entered into an agreement with Lucent to purchase, over a four year
period, 300 cell sites, two switches and certain related hardware and software.
The aggregate net cost to us under this agreement is estimated to be $81.0
million. We are also a party to another equipment supply agreement, with Nortel,
to purchase approximately $65.0 million of cell site and switching equipment
over the period June 1997 to November 2001.
 
    We expect our cell site expansion to enable us 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. We believe that the increased
cellular coverage will have a positive impact on market penetration and
subscriber usage.
 
    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. We use two basic protocols in our digital networks. Our
primary digital technology or "protocol" is TDMA (Time Division Multiple Access)
which is a satellite and cellular phone technology that interleaves multiple
digital signals onto a single high-speed channel. For cellular, it divides each
channel into three subchannels providing service to three users instead of one.
Our other digital technology or "protocol" is CDMA (Code Division Multiple
Access) that converts analog signals into digital for transmission over our
cellular network. It provides up to 35 times the capacity of the analog network.
 
    While the FCC has mandated that licensed cellular systems in the United
States 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 able to use a handset in an area served by a
system using CDMA only if it is a dual-mode handset that permits the subscriber
to use the digital cellular system in that area. Dual-mode handsets for
TDMA/CDMA are not yet available and analog/TDMA handsets have only recently
become available. However, the FCC or industry organizations may decide to move
toward a universal digital switching protocol in the future.
 
   
    We believe that the primary advantages and disadvantages of TDMA and CDMA
are that CDMA generally provides a greater capacity than TDMA so that more calls
can be handled at one time, while TDMA is less difficult and, therefore, less
expensive to maintain. We believe that it is highly unlikely that CDMA would
become the accepted standard in the cellular telephone industry. However, if
such should occur, we expect that we would replace our TDMA with CDMA
technology, which would require us to
    
 
                                       69
<PAGE>
   
make significant capital expenditures. Because we believe it is so unlikely that
CDMA will become the accepted standard, we have not estimated the cost we would
incur in such event.
    
 
    Over the next decade, we expect 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, it may not be
possible to complete certain calls, 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. We expect the conversion from analog to
digital technology to be an industry-wide process that will take a number of
years to complete. We have completed the conversion of many of our systems to
digital technology and expects to convert the remainder of our systems (except
for Kansas/ Missouri) by the end of 1999.
 
    The technology which we utilize will be governed, to a large extent, by the
technology used by the large, dominant carriers in MSAs near our systems. The
timing of the conversions will be governed by the conversion rate of larger,
neighboring MSAs, market conditions and financial considerations.
 
    The following table reflects the digital technology currently used or
expected to be selected by us in each of its cellular markets.

    INFORMATION SYSTEMS.  Billing functions for most of our cellular operations
are provided by International Telecommunications Data Service ("ITDS").
Proprietary software furnished by ITDS serves all functions of billing for
corporate and retail locations. All administrative and customer maintenance
functions are handled in-house with invoice processing and printing handled by
ITDS. In the first quarter of 1999, we began replacing ITDS with another billing
vendor, H.O. Systems, Inc. The H.O. Systems'
 
                                       70

software is in place and functioning in our Western Region markets and we intend
to implement the H.O. Systems' software throughout our remaining regions by the
end of the third quarter of 1999. We use complementing software to the billing
system allowing the use of credit, collection and switch interfaces.
 
    We operate a Nortel Meridian phone system with voice mail features. In
addition, our customer service and collections groups extensively utilize the
automatic call distribution queues and traffic and productivity reporting
capacities of the system.
 
    SERVICE MARKS
 
    We own the service mark Dobson Cellular-TM- which we use in our cellular
telephone systems in western Oklahoma. While we have not attempted to federally
register the brand name "Dobson Cellular," we believe that our prior use of this
brand name in the limited areas where it is used will enable us to effectively
police against any infringing uses of such brand name.
 
    The following table sets forth the brand names used, or intended to be used,
by us for products and services in each of our cellular markets:

    The telecommunications industry is experiencing significant technological
changes, 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, we expect
competition in the wireless telecommunications industry 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 we compete are served by other two-way wireless
service providers, including licensed cellular and PCS operators and resellers.
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 us. Some competitors are expected to
market other services, such as long distance, landline local exchange and
internet access service, with their cellular telecommunication service
offerings. Several of our competitors are operating, or planning to operate,
through joint ventures and affiliation arrangements, wireless telecommunications
systems that encompass most of the United States.
 
    We compete primarily against one other facilities-based cellular carrier in
each of our cellular markets. We compete for customers based principally upon
price, the services and enhancements offered, the quality of the cellular
system, customer service, system coverage and capacity. This 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.
 
                                       72
<PAGE>
    We also face to a lesser extent competition from PCS, ESMR and mobile
satellite service ("MSS") providers, as well as from resellers of these services
and cellular service. In the future, we 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. Recently, the FCC
has created potential sources of new competition by auctioning additional PCS
licenses, as well as licenses for Wireless Communications Services, local
multipoint Distribution Service and 220-222Mhz service. Further, the FCC has
announced plans to auction licenses in the General Wireless Communications
Services.
 
    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 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 of the PCS licensees that compete, or will compete, with us
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 Communications, Inc., 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 we may experience increased
competition from low earth-orbit satellite-based systems in the future, to date,
such systems have not affected our operations.
 
    The commercial development and deployment of most of these new technologies
remain in an early phase. We expect 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. We believe that we can
effectively face this competition from our position as an incumbent in the
cellular industry with
 
    - a high quality network,
 
                                       73
<PAGE>
    - extensive home rate areas that are not capacity constrained,
 
    - strong distribution channels,
 
    - superior customer service capabilities, and
 
    - an experienced management team.
 
    Since we operate in medium to small markets, new entrants in those markets
may be unable to offer wireless service at competitive rates markets in the near
term. The extensive capital 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 we operate.
 
REGULATION
 
   
    OVERVIEW.  The wireless telecommunications industry is subject to extensive
governmental regulation on the federal level and to varying degrees on the state
level. The enactment of the Telecommunications Act has impacted many aspects of
this regulation. In addition, this regulation is currently the subject of
administrative rulemakings and judicial proceedings that are significant to us.
The following is a summary of the federal laws and regulations that materially
affect the wireless telecommunications industry, in general, and us, in
particular, and a description of applicable 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 wireless telecommunications
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 comprised of 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 or entity may
have an attributable interest, as defined in FCC rules, in a total of more than
45 MHz of licensed broadband PCS, cellular and ESMR spectrum, regulated as CMRS,
with significant overlap in any geographic area. Significant overlap will occur
when at least 10% of the 1990 census population of the PCS licensed service area
is within the CGSA, as defined below, and/or the ESMR service area. The FCC is
currently considering whether it should modify this 45 MHz spectrum cap.
    
 
    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 smaller if a licensee has chosen not to provide
services to certain areas. 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, other entities may apply to serve portions
of the MSA or RSA, of at least 50 square miles in areas outside the licensee's
then designated CGSA. The five year build-out period has expired for most
licensees and the FCC has granted several "unserved area" applications filed by
parties other than the original MSA or RSA licensee. Sygnet's five year buildout
 
                                       74
<PAGE>
   
period has expired in all its markets, except Pennsylvania 2 RSA. Our buildout
has been substantially completed in all of our markets except Ohio RSA 2, Texas
10 RSA and 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. We are obligated to pay annual regulatory fees and assessments to
support the FCC's regulation of its cellular operations, as well as fees
necessary to support centralized administration of telephone numbering,
telecommunications relay service ("TRS") for the hearing-impaired and
application filing fees.
 
   
    The Communications Act requires prior FCC approval for substantive,
non-proforma transfers or assignments to or from us of a controlling interest in
any license or construction permit, or any rights thereunder. Although we cannot
assure you that the FCC will approve or timely act upon any future requests for
approval of applications that we file, we have no reason to believe that the FCC
would not approve or grant such requests or applications 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. Moreover, federal legislation enacted in 1993 requires the
FCC to reduce the disparities in the regulatory treatment of similar mobile
services, such as cellular, PCS and ESMR. Under this new regulatory structure,
all of our cellular licenses are classified as CMRS. As a CMRS provider, the FCC
regulates us as a common carrier. The FCC, however, has exempted cellular
services from some typical common carrier regulations, such as tariff filings.
The FCC has also adopted requirements for cellular and other CMRS providers 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. Our obligations to implement these services is scheduled to occur in
several stages ending in October 2001. Federal regulations also require cellular
and PCS carriers 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 us 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
November 24, 2002. These requirements may result in added capital expenditures
for us to make necessary system changes, although we currently have no plans for
any such expenditures.
    
 
   
    The FCC generally grants cellular and PCS licenses for terms of ten years
that are renewable upon application to the FCC. Near the conclusion of the
license term, we must file applications for renewal of licenses to obtain
authority to operate for an additional 10-year term. The FCC may revoke our
licenses and may deny our license renewal applications for cause after
appropriate notice and hearing. The FCC
    
 
                                       75
<PAGE>
   
will award a renewal expectancy to us if we meet certain standards of past
performance. If we receive a renewal expectancy, it is very likely that the FCC
will renew the area existing cellular license without becoming subject to
competing applications. To receive a renewal expectancy, we must show that we
have provided "substantial" service during our past license term, and have
substantially complied with applicable FCC rules and policies and the
Communications Act. The FCC defines "substantial" service as service which is
sound, favorable and substantially above a level of mediocre service that might
only minimally warrant renewal. If a licensee does not receive a renewal
expectancy, then the FCC will accept competing applications for the license,
subject to a comparative hearing, and the FCC may award the license to another
entity. The initial term for three of our existing licenses, apart from those we
acquired from Sygnet, expired in October 1998. The FCC has renewed each license
for a new ten year term expiring in 2008. The balance of our existing licenses
begin to expire in October 2000. The FCC has renewed three of the licenses we
acquired from Sygnet for a new ten year term, and the initial terms on the
balance of these licenses will expire beginning in 2006.
    
 
   
    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 possessions and territories into PCS markets based upon Rand McNally's 493
BTAs, all of which are included in the 51 MTAs. 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, 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. In 1998,
the FCC afforded financially-troubled C Block licensees the option of returning
all or half of their spectrum to the FCC for reauction. On April 15, 1999, the
FCC completed a reauction of PCS licenses in the C, E and F Blocks. A total of
302 licenses will be awarded (179 30 MHz C Block, 115 15 MHz C Block, 6 E Block
and 2 F Block), assuming full payment by all winning bidders.
    
 
   
    The FCC has adopted standards to apply to PCS renewals under which the FCC
will award a renewal expectancy using standards similar to those applied to
cellular licensees. Additionally, all 30 MHz broadband PCS licensees must
construct facilities that offer coverage to one-third of the population of their
service area within five years, and two-thirds of the population within ten
years, of their initial license grants. All 10 MHz and 15 MHz licensees must
provide service to at least 25% of the service area or make a showing of
"substantial service" within five years of their initial license. Licensees that
fail to meet the coverage requirements may be subject to forfeiture of the
license.
    
 
   
    FCC rules restrict the voluntary assignments or transfers of control of
certain licenses awarded to "small businesses" with bidding enhancements in the
C Block and F Block auctions. During the first five years of the license term,
assignments or transfers affecting control are permitted only to assignees or
transferees that meet the eligibility criteria for participation in the
entrepreneur block auction at the time the application for assignment or
transfer of control is filed or, if the proposed assignee or transferee holds
other licenses for C Block and F Block, met the same eligibility criteria at the
time of receipt of such licenses. Any transfers or assignments by licensees that
qualified for installment payments during the entire ten-year initial license
terms are subject to unjust enrichment penalties; i.e., acceleration of any
installment payment plans should the assignee or transferee not qualify for the
same benefits. Any transfers or assignments by licensees that qualified for
bidding credits during the first five years of the license term are subject to
unjust enrichment penalties; i.e., forfeiture of any bidding credit based upon
the amount of time the initial license has been held should the assignee or
transferee not qualify for these same benefits. In the case of the C Block and F
Block, the FCC will conduct random audits to ensure that licensees are in
compliance with the FCC's eligibility rules. Violations of the Communications
Act or the FCC's rules could result in license revocations, forfeitures or
fines. We were qualified to hold C and F licenses at the time such licenses were
awarded, and we anticipate remaining so qualified throughout the term of the PCS
licenses awarded to us.
    
 
                                       76
<PAGE>
   
    For a period of up to five years after the grant of a PCS license (subject
to extension), the FCC prohibits a PCS licensee from interfering with existing
licensees that operate certain fixed microwave systems within its license area.
To secure a sufficient amount of unencumbered spectrum to operate our PCS
systems efficiently and with adequate population coverage, we may need to
relocate many of these incumbent licensees, at our expense, to other frequencies
or to reimburse other previously-licensed PCS licensees for expenses they have
incurred in relocating incumbent licensees that we might otherwise have been
required to relocate. In an effort to balance the competing interests of
existing microwave users and newly authorized PCS licensees, the FCC has adopted
a transition plan to relocate such microwave operators to other spectrum blocks
and a cost sharing plan so that if the relocation of an incumbent benefits more
than one PCS licensee, the benefitting PCS licensees will share the cost of the
relocation. This transition plan allows most microwave users to operate in the
PCS spectrum for a one-year voluntary negotiation period and an additional
one-year mandatory negotiation period. For public safety entities dedicating a
majority of their system communications for police, fire or emergency medical
services operations, the voluntary negotiation period is three years, with an
additional two-year mandatory negotiation period. After the voluntary and
mandatory negotiation periods expire, the microwave user continues to hold
primary status until April 4, 2005, but may be involuntarily relocated, albeit
at the PCS licensee's expense. Parties unable to reach agreement within these
time periods may refer the matter to the FCC for resolution, but the incumbent
microwave user is permitted to continue its operations until final FCC
resolution of the matter. The transition and cost sharing plans expire on April
4, 2005, at which time remaining incumbents in the PCS spectrum will be
responsible for their costs to relocate to alternate spectrum locations. We have
not yet determined the extent, if any, of expenses we may need to incur for the
relocation of microwave incumbents in order to provide PCS services using our
the PCS licenses.
    
 
   
    The FCC may deny applications for FCC authority, and in extreme case revoke
licenses, if it 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. Moreover, if
foreign nationals or their representatives, a foreign government or its
representative or any corporation organized under the laws of a foreign country
own of record or vote greater than 25 percent of our equity and the FCC
determines that the public interest would be so served, it may revoke our
cellular licenses or require an ownership restructuring. However, 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 our ability to attract
additional equity financing. We have no knowledge that any foreign national owns
any of our capital stock.
    
 
   
    The Telecommunications Act, which made 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. In a rulemaking proceeding pertaining to interconnection
between local exchange carriers ("LECs") and CMRS providers such as us, the FCC
concluded that LECs are required to compensate CMRS providers for the reasonable
costs incurred by such providers in terminating traffic that originates on LEC
facilities,
    
 
                                       77
<PAGE>
   
and vice versa. Consistent with this ruling, the FCC has determined that LECs
may not charge a CMRS provider or other carrier for terminating LEC-originated
traffic. Nor may LECs charge CMRS providers for number activation and use fees.
Depending on further FCC disposition of these issues, we may or may not be
successful in securing refunds, future relief or both, with respect to charges
for termination of LEC-originated local traffic. If these issues are ultimately
resolved by the FCC in favor of CMRS providers, then we will pursue relief
through settlement negotiations, administrative complaint procedures or both. If
these issues are ultimately decided in favor of the LECs, we likely would be
required to pay all past due contested charges and may also be assessed interest
and late charges for the withhold amounts. These requirements could in the
future have a material effect on us.
    
 
   
    The Telecommunications Act requires, and the FCC has adopted, 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 our cellular operations. The Telecommunications
Act also eases the restrictions on the provision of interexchange telephone
services by wireless carriers affiliated with RBOCs. RBOC-affiliated wireless
carriers have interpreted the legislation to permit immediate provision of in
region long distance call delivery for their cellular customers.
    
 
   
    Additionally, 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. We currently provide "dial around" equal access to all of
our customers.
    
 
   
    The Telecommunications Act also imposes restrictions on a telecommunications
carrier's use of customer proprietary network information without prior customer
approval. FCC rules implementing these restrictions are being reviewed but have
the potential to impose upon us new costly obligations and impose burdens on our
current marketing activities.
    
 
   
    The overall impact of the Telecommunications Act on our business is unclear
and will likely remain so for the foreseeable future. New limitations on local
zoning requirements may facilitate the construction of new cell sites and
related facilities. See "--State, Local and Other Regulation." However, these
restrictions on zoning authority may provide only limited assistance to cellular
carriers, and other provisions of the new statute relating to interconnection,
telephone number portability, universal service, equal access, use of customer
proprietary network information and resale could subject us 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 CMRS or any
private mobile service provider, which includes cellular telephone service
providers. The FCC has denied the petitions of eight states to continue their
rate regulation authority, including authority over cellular operators. As a
practical matter, we are free to establish rates and offer new products and
service with a minimum of regulatory requirements. The states in which we
operate maintain nominal oversight jurisdiction, primarily focusing upon prior
approval of acquisitions and transfers and resolution of customer complaints.
    
 
   
    The location and construction of our cellular transmitter towers and
antennas are subject to FCC and Federal Aviation Administration ("FAA")
regulations and are subject to federal, state and local environmental
regulation, as well as state or local zoning, land use and other regulation.
Before we can put a system into commercial operation, we must obtain all
necessary zoning and building permit approvals for the cell site microwave tower
locations. 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. Additionally, any proposed site must comply
with the FCC's environmental rules.
    
 
                                       78
<PAGE>
   
    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 may provide facilities some relief from state and local
laws that arbitrarily restrict the construction of personal wireless services,
which include cellular, PCS and ESMR systems. For example the Telecommunications
Act precludes localities from denying zoning approval for cell sites based upon
electromagnetic emission concerns, if the personal wireless service operator's
system complies with FCC emissions standards. In addition, the
Telecommunications Act prohibits localities from adopting zoning requirements
that simply 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.
    
 
   
    We cannot assure you that any state or local regulatory requirements
currently applicable to our 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, federal or state legislators propose
legislation that could affect us, either beneficially or adversely. We cannot
assure you that federal or state 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 our business. Changes such as the
allocation by the FCC of radio spectrum for services that compete with our
business could adversely affect our operating results.
    
 
EMPLOYEES AND AGENTS
 
    As of December 31, 1998, we had approximately 980 employees. In addition, as
of such date, we had agreements with 339 independent sales agents, including car
dealerships, electronics stores, paging service companies and independent
contractors. None of our employees are represented by a labor organization, and
we consider our employee relations to be good.
 
PROPERTIES
 
    We maintain our corporate headquarters in Oklahoma City, Oklahoma. We lease
approximately 24,600 square feet at a monthly rental of approximately $19,000.
See "Management--Certain Transactions." As of December 31, 1998, our cellular
operations leased 67 and owned five sales and administrative offices, at
aggregate annual rentals of approximately $1.6 million. We anticipate that we
will review these leases from time to time and may, in the future, lease or
acquire new facilities as needed. We expect to lease or purchase additional
sales and administrative office spaces in connection with the pending
acquisitions. We do not anticipate that it will encounter any material
difficulties in meeting our future needs for any leased space. We also owned and
leased 414 cell sites as of December 31, 1998.
 
LEGAL PROCEEDINGS
 
    We are not currently involved in any pending legal proceedings that
individually or in the aggregate are material to us. We are a party to routine
filings and customary regulatory proceedings with the FCC and the state public
utility commissions relating to our operations.

    option exercise price and (ii) number of underlying securities at December
    31, 1998.
 
EMPLOYMENT AGREEMENTS
 
    In connection with the employment of Bruce R. Knooihuizen in 1996 and G.
Edward Evans in 1997, we agreed to provide them compensation in the form of

employment are an initial annual salary of $150,000, an annual bonus ranging
from 30% to 50% of his annual salary, and a 10-year option to purchase 7,541
shares of our Class B Common Stock at $100 per share vesting at the rate of 20%
per year. The terms of Mr. Evans'
 
                                       83
<PAGE>
employment are an initial annual salary of $120,000, an annual bonus ranging
from 30% to 50% of his annual salary, a five-year home mortgage loan of $300,000
at an annual interest rate of 4%, and a ten-year option to purchase 6,033 shares
of our Class B Common Stock at $100 per share, with 60% of the option vesting
ratably over five years and 40% vesting over five years based on the achievement
of annual performance objectives. We also agreed to a severance payment equal to
one year's salary in the event of termination of employment of Messrs.
Knooihuizen or Evans without cause. The options to purchase shares of our Class
B Common Stock held by these officers become fully vested upon a change of
control.
 
   
    Effective September 1, 1998, we entered into a consulting agreement with
Russell L. Dobson. Under the terms of the agreement, Mr. Dobson has been
retained by us from September 1, 1998 through August 31, 2008. In exchange for
Mr. Dobson's services, we will provide monthly compensation of $15,000 and
insurance benefits commensurate with our employee plan. Mr. Dobson's
responsibilities include representing us at various functions, assisting with
regulatory matters and assisting executive officers in strategic planning and
forecasting. In addition, Mr. Dobson has agreed not to compete with us. During
1998, we paid Mr. Dobson approximately $195,000 under the consulting agreement.
    
 
   
    Effective December 23, 1998, Albert H. Pharis, Jr. became a consultant to
us, to assist us on an as-needed basis, for term of five years. Mr. Pharis will
receive a fee of $40,000 for the first 90 days of such consulting period and an
annual fee of $60,000 thereafter. In addition, Mr. Pharis received options to
purchase 833 shares of our Class B Common Stock at an exercise price of $665 per
share. Mr. Pharis's option vests ratably over a five-year period and fully vests
upon a change of control.
    
 
DIRECTOR COMPENSATION
 
    We reimburse directors for out-of-pocket expenses incurred in attending
board meetings. Justin L. Jaschke, in connection with his election as a director
in October 1996, was granted an option to acquire 833 shares of our Class B
Common Stock at an exercise price of $100 per share. Mr. Jaschke's option vests
ratably over a five-year period and fully vests upon a change of control.
Directors who are our officers or our consultants receive no additional
compensation for services rendered as directors.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
   
    The Compensation Committee of the Board of Directors determines the
compensation of our executive officers. During fiscal year 1998, the members of
the Compensation Committee were Russell L. Dobson, Justin L. Jaschke and Thadeus
J. Mocarski, a former director. Russell L. Dobson previously served as Chairman
of the Board and Chief Executive Officer from 1990 to 1996. Commencing in
February 1999, the members of our Compensation Committee are Russell L. Dobson
and Dana L. Schmaltz. For a description of certain transactions between Mr.
Dobson and us, see "--Certain Transactions."
    
 
STOCK OPTION PLAN
 
   
    We adopted our 1996 Stock Option Plan, as amended (the "Plan") to encourage
our key employees by providing opportunities to participate in ownership and our
future growth through the grant of incentive stock options and nonqualified
stock options. The Plan also permits the grant of options to our directors. The
Plan is presently administered by our Board of Directors, but in the future may
be administered by a committee of the Board (whether the Board or a committee,
the "Committee"). As of March 31, 1999 we had granted options to purchase an
aggregate of 29,767 shares of Class B Common Stock and 3,622 shares of Class C
Common Stock under the Plan.
    
 
   
    The maximum number of shares for which we may grant options under the Plan
is 30,166 shares of Class B Common Stock and 30,166 shares of Class C Common
Stock, subject to adjustment in the event of any stock dividend, stock split,
recapitalization, reorganization or certain defined change of control events.
Shares subject to previously expired or terminated options become available
again for grants of options. The shares that we will issue under the Plan will
be newly issued shares.
    
 
                                       84
<PAGE>
    The Compensation Committee determines the number of shares and other terms
of each grant. The price payable upon the exercise of an incentive stock option
may not be less than 100% of the fair market value of our Class B Common Stock
and the Class C Common Stock at the time of grant, or in the case of an
incentive stock option granted to an employee owning stock possessing more than
10% of the total combined voting power of all classes of our stock (a "10%
Shareholder"), 110% of the fair market value on the date of grant. We may grant
incentive stock options to an employee only to the extent that the aggregate
exercise price of all such options under all of our plans becoming exercisable
for the first time by the employee during any calendar year does not exceed
$100,000. The price payable upon the exercise of a nonqualified stock option
must be at least the minimum legal consideration required under the laws of
Oklahoma.
 
   
    Each option that we have granted or will grant under the Plan will expire on
the date specified by the Committee, but not more than ten years from the date
of grant or, in the case of a 10% Shareholder, not more than five years from the
date of grant. Unless otherwise agreed, an incentive stock option will terminate
not more than 90 days (or twelve months in the event of death or disability)
after the optionee's termination of employment.
    
 
    An optionee may exercise an option by giving notice to us, accompanied by
full payment of the purchase price in cash or, at the discretion of the
Committee,
 
   
    - common stock having a fair market value equal to the exercise price,
    
 
    - the optionee's personal recourse note bearing interest payable not less
      than annually at no less than 100% of the lowest applicable federal rate
      (as defined in Section 1274(d) of the Internal Revenue Code),
 
    - an assignment of proceeds from the sale of a portion of the stock subject
      to the option being exercised, or
 
    - a combination of the foregoing.
 
    Outstanding options become nonforfeitable and exercisable in full
immediately prior to certain defined change of control events. Unless otherwise
determined by the Committee, outstanding options will terminate immediately
prior to the consummation of our dissolution or liquidation.
 
    The Plan may be terminated or amended by the Board of Directors at any time
subject, in the case of certain amendments, to shareholder approval. If not
earlier terminated, the Plan expires on June 1, 2006.
 
CERTAIN TRANSACTIONS
 
    We have adopted a policy requiring that any material transaction between us
and persons or entities affiliated with our officers, directors or principal
stockholders be on terms no less favorable to us than reasonably could have been
obtained in an arms' length transaction with independent third parties. Any
other matters involving potential conflicts of interests are to be resolved on a
case-by-case basis.
 
    The Everett R. Dobson Irrevocable Family Trust, Steven T. Dobson Irrevocable
Family Trust and Robbin L. Dobson Irrevocable Family Trust, (collectively, the
"Dobson Trusts") are the limited partners of the Dobson Partnership, which holds
95.8% of the our Class A Common Stock.
 
    Prior to November 1, 1998, we leased our headquarters from WillRuss Limited
Liability Company ("WillRuss") pursuant to a 10-year lease expiring in 2005.
WillRuss is owned by Russell L. Dobson and his wife. Monthly rent under the
lease was approximately $23,000, or $.93 per square foot. In October 1998,
WillRuss sold this building to an unrelated third party. As part of the sale
transaction, we entered into an agreement with the buyer to lease the building
for a one-year term at a monthly rent of approximately $19,000. In August 1995,
we loaned WillRuss $60,000, which was paid in full in September 1995, together
with interest at an annual rate of 10%.
 
                                       85
<PAGE>
    We made a $300,000 home mortgage loan to G. Edward Evans in February 1997 in
connection with his employment. See "--Employment Agreements." The loan is
payable in 60 monthly installments of $1,400, including interest at the annual
rate of 4%, with the balance due at maturity in February 2002.
 
    In the Reorganization in February 1997, the shareholders of DOC exchanged
their DOC stock for our stock, and we assumed outstanding DOC stock options,
substituting shares of our Class B Common Stock for the DOC stock subject to
options. Also, in February 1997, we issued 100,000 shares of our Class C
Preferred Stock. See "Description of the Preferred Stock."
 
    Transactions with us described below refer to DOC if they occurred prior to
February 1997.
 
    In March 1996, the Fleet Investors purchased 100,000 shares of our Class B
Preferred Stock for $10.0 million. In connection with this transaction, we
entered into a Shareholders' Agreement providing for, among other matters,
registration rights, restrictions on the transfer of our stock, put and call
rights with respect to the Class B Preferred Stock, and the issuance of
additional stock upon the happening of certain events. The Fleet Investors also
granted us a stock option. In connection with the Reorganization, we entered
into a new Shareholders' Agreement having substantially the same terms and
conditions. In January 1998, we issued the Fleet Investors 100,000 shares of our
Class C Preferred Stock. In connection with the Sygnet acquisition, the Fleet
Investors converted their Class B Preferred Stock into Class A Common Stock and
disposed of all their Class A Common Stock and Class C Preferred Stock. In
addition, the Shareholders' Agreement was terminated.
 
   
    The Dobson Trusts, were co-borrowers with us and certain of our subsidiaries
under a prior bank facility, which was first entered into in 1994. We
guaranteed, and pledged the equity securities of certain of our subsidiaries as
security for, the obligations of the Dobson Trusts under a $6.0 million
promissory note maturing in 2004 (the "Trust Loan"), and the Dobson Partnership
guaranteed our loan obligations and those of our subsidiaries under the prior
bank facility. All borrowings were secured by shares of our Class A Common
Stock. We paid dividends on the Class A Common Stock in amounts sufficient to
permit the Dobson Trusts to service the Trust Loan. The Dobson Trusts incurred
legal fees totaling approximately $.5 million in connection with the negotiation
and closing of the credit agreement for the prior bank facility in 1994 and an
amendment effected in 1996. Such fees were paid by us. We used $7.5 million of
bank borrowings to pay a dividend to holders of our Class A Common Stock, of
which $6.0 million was used to fully pay the Trust Loan and $.5 million was used
to pay indebtedness owed to us by the Dobson Trusts with respect to the legal
fees described above.
    
 
   
    Everett R. Dobson and Russell L. Dobson beneficially owned 67% of the
capital stock of ATTI. In December 1996, we consolidated $263,000 of ATTI's
outstanding indebtedness to us in an unsecured promissory note which provided
for interest at an annual rate of 10%. The consolidation refinanced earlier
loans made prior to 1994. At September 30, 1997, National Telecommunications
Technologies, Inc. ("Natelco"), a wholly-owned subsidiary of ATTI, was indebted
to us in the aggregate principal amount of $307,000, representing funds we
advanced during 1992, 1993 and 1995. The indebtedness was evidenced by an
unsecured promissory note which provided for interest at an annual rate of 10%.
The ATTI and Natelco loans (combined principal amount of $570,000) were paid in
full on October 1, 1997 in connection with the closing of our acquisition of the
Arizona 5. We loaned another subsidiary of ATTI $21,000 in 1994 and $32,000 in
1995, at annual interest rates of 12% and 14%, respectively. These loans were
paid in full in October 1995 and January 1996.
    
 
    Through September 30, 1997, we performed certain management services for
ATTI and its subsidiaries, including accounting, plant and central office
management and engineering. Billings for the services were based on the time
spent by, and hourly rates of, our personnel and expenses incurred. During 1995,
1996, and the nine months ended September 30, 1997, the aggregate amounts billed
for management fees and expenses to ATTI and its subsidiaries were approximately
$210,000, $333,000 and $110,000, respectively. The amounts owed by these
entities to us for management fees at December 31, 1995 and 1996 and September
30, 1997 were $1.0 million, $1.2 million and $1.3 million, respectively. All
amounts owed by
 
                                       86
<PAGE>
ATTI and it subsidiaries for management services rendered prior to September 30,
1997 were paid in October 1997 in connection with the closing of our acquisition
of Arizona 5. In connection with our Arizona 5 acquisition, ATTI became our
wholly owned subsidiary, and a new company, NATELCO, LLC (an affiliate of
Everett R. Dobson and Russell L. Dobson), was created. For the years ended
December 31, 1997 and 1998 the amounts billed for management fees and expenses
to NATELCO, LLC were $21,000 and $47,466, respectively. The amounts owed by
NATELCO, LLC to us for management fees at December 31, 1997 and 1998 were $8,900
and $0, respectively.
 
   
    ATTI beneficially owned a 20.55% partnership interest in the Arizona 5
Partnership. In connection with the Arizona 5 Acquisition, we purchased all of
the outstanding capital stock of ATTI for $14.2 million, of which Everett R.
Dobson and Russell L. Dobson, together, received $9.5 million. The purchase
price for the ATTI stock was based on ATTI's beneficial ownership in the Arizona
5 Partnership and our negotiations with the other partner of the Arizona 5
Partnership.
    
 
    In March 1996, we made a $1.4 million unsecured loan to Everett R. Dobson.
The loan was repaid on October 1, 1997 in connection with our Arizona 5
Acquisition. Interest on the amount borrowed was payable quarterly at the same
annual rate as that payable under our prior bank facility. The loan consolidated
amounts borrowed prior to 1994, together with accrued interest.
 
    In June 1997, Everett R. Dobson executed a promissory note in our favor for
approximately $354,000, which refinanced loans made to him during 1996, together
with accrued interest. The loan was repaid on October 1, 1997 in connection with
our Arizona 5 acquisition. The loan bore interest at 8% per annum. In December
1996, we made a one-year loan in the amount of $12,900 to Russell L. Dobson
which bore interest at 9% per annum. In June 1997, we made an additional loan to
Russell L. Dobson in the principal amount of $423,000, of which $304,000
consolidated amounts owed to us since prior to 1994, and $119,000 refinanced a
loan made to him in November 1996, in each case together with accrued interest.
This loan bore interest at an annual rate of 9.07%. Both loans to Russell L.
Dobson were paid in full on October 1, 1997 in connection with our Arizona 5
Acquisition. The interest rate charged on our loan to Everett R. Dobson
represented our costs of borrowed funds. The interest rate on the loans to
Russell L. Dobson approximated the prevailing market rates at the time the loans
were first made.
 
   
    In 1995, we bought 75,000 shares of common stock of Zenex for $75,000 and
400,000 shares of Zenex preferred stock for $400,000, and received an option to
purchase additional shares of Zenex common stock. In early 1996, we purchased an
additional 275,000 shares of Zenex preferred stock for $275,000. In October
1996, Zenex redeemed all shares of Zenex preferred stock held by us and
purchased our option for an aggregate of $825,000. At the same time, the Company
sold 30,000 shares of Zenex common stock to an unrelated party for $142,000. In
July 1997, we purchased 30,000 shares of Zenex common stock for $150,000 and
resold the shares in November 1997 to Everett R. Dobson at a price equal to our
cost. In September 1997, we purchased a loan for $263,882 made by a bank to
Zenex and resold such loan to Everett R. Dobson in November 1997 at a price
equal to our cost plus accrued interest. Everett R. Dobson was director of Zenex
from August 1995 to September 1997.
    
 
    In November 1997, Everett R. Dobson purchased an interest in our loan to
Gila River Telecommunications Subsidiary, Inc., a wholly owned subsidiary of the
Gila River Indian Community. We repurchased this interest in June 1998.
 
    In January 1998, our subsidiary purchased contractual rights, information
data and other rights with respect to certain of Zenex's long distance customers
located in areas served by Logix for $105,000. In addition, in June, 1998, Logix
purchased certain long distance customers and related assets for approximately
$4.7 million. In connection with the purchase of these assets of Zenex, a note
payable in the amount of $284,765, including accrued interest, from Zenex to
Everett R. Dobson was paid in full.
 
    In connection with the Sygnet acquisition, we purchased for $1.9 million all
of our outstanding shares (100,000 shares) of Class C Preferred Stock held by
the Fleet Investors and also purchased 43,348 shares of
 
                                       87
<PAGE>
our Class A Common Stock from Fleet Investors for $31.1 million. Thadeus J.
Mocarski, a principal of the Fleet Investors, was one of our directors and
resigned as a director upon consummation of the Sygnet acquisition. As part of
the Sygnet acquisition, the Dobson Partnership acquired 37,630 shares of Class G
Preferred Stock from us in exchange for 37,630 shares of Class A Common Stock.
See "Description of Capital Stock--Other Preferred Stock" for a description of
the Class D Purchase Agreement and Investors Agreement which we entered into in
connection with the Sygnet acquisition.
 
   
    In the Tower Sale Leaseback, Dobson Tower Company purchased cellular towers
from Sygnet for $25.0 million and leased the towers back to Sygnet. Everett R.
Dobson, one of our directors, executive officers and principal shareholders,
owns preferred stock issued by Dobson Tower Company. All of Dobson Tower
Company's common stock is owned by us.
    
 
   
    On May 5, 1999 we expect to redeem all outstanding shares of our Class G
Preferred Stock for $25 million plus accrued dividends of $1,000,000. All of the
Class G Preferred Stock was initially acquired by the Dobson Partnership in
December 1998 as part of the financing of our acquisition of Sygnet and in
exchange for shares of our outstanding common stock valued at $25.0 million.
    
 
    In connection with our acquisition of Sygnet and the related financing, we
engaged in a number of transactions with the Dobson Partnership and with Childs.
See "Description of Capital Stock--Other Preferred Stock."

                       DESCRIPTION OF THE PREFERRED STOCK
 
    The following summary of certain provisions of the Preferred Stock is not
complete and is qualified in its entirety by reference to the provisions of the
certificate of designation for the Preferred Stock (the "Certificate of
Designation"), a copy of the form of which we will make available upon request.
The definitions of certain terms used in the Certificate of Designation and in
the following summary are set forth under "--Certain Definitions." In this
description, "Dobson" or "Dobson Communications" refers only to Dobson
Communications and not to any of our subsidiaries.
 
GENERAL
 
   
    Our Certificate of Incorporation authorizes the Board of Directors to issue
classes of preferred stock from time to time in one or more series, with such
designations, voting powers, preferences and relative, participating, optional
or other special rights, qualifications, limitations or restrictions as may be
determined by the Board of Directors. We have authorized 3,000,000 shares of
preferred stock, par value $1.00, including 184,000 shares of Preferred Stock,
with a liquidation preference of $1,000 per share. These shares include the
65,152 shares of Preferred Stock issued in Old Shares and additional shares of
Preferred Stock which may be used to pay dividends on the Preferred Stock if we
elect to pay dividends in additional Preferred Stock. We filed a Certificate of
Designation with respect thereto with the Secretary of State of Oklahoma as
required by Oklahoma law. The Preferred Stock is exchangeable, at our option,
into the Exchange Debentures, at any time. See "--Exchange." The outstanding
Preferred Stock is fully paid and nonassessable and the holders thereof have no
subscription or preemptive rights related thereto. United States Trust Company
of New York will be the transfer agent and registrar for the Preferred Stock
(the "Transfer Agent" and "Registrar").
    
 
RANKING
 
    The Preferred Stock, with respect to dividend distributions and
distributions upon the liquidation, winding-up and dissolution of Dobson, ranks
 
    - senior to all classes of our Common Stock, our Class A Preferred Stock,
      the Class D Preferred Stock, Class E Preferred Stock, Class F Preferred
      Stock, Class G Preferred Stock, Class H Preferred Stock and to each other
      class of capital stock or series of preferred stock established in the
      future by the Board of Directors, the terms of which do not expressly
      provide that it ranks senior to or on a parity with the Preferred Stock as
      to dividend distributions and distributions upon our liquidation,
      winding-up and dissolution (collectively referred to, together with all
      classes of our common stock, as our "Junior Securities");
 
    - equal with the Senior Preferred Stock and, subject to certain conditions,
      with any class of capital stock or series of preferred stock which we may
      issue in the future, the terms of which expressly provide that such class
      or series will rank on a parity with the Preferred Stock as to dividend
      distributions and distributions upon our liquidation, winding-up and
      dissolution (collectively referred to as "Parity Securities"); and
 
    - subject to certain conditions, junior to each class of capital stock or
      series of preferred stock which we may issue in the future, the terms of
      which expressly provide that such class or series will rank senior to the
      Preferred Stock as to dividend distributions and distributions upon our
      liquidation, winding-up and dissolution (collectively referred to as
      "Senior Securities").
 
    The Preferred Stock is subject to the issuance of series of Junior
Securities, Parity Securities and Senior Securities, PROVIDED that we may not
issue any new class of Senior Securities without the approval of the holders of
at least a majority of the shares of Preferred Stock then outstanding, voting or
consenting, as the case may be, separately as one class, except that, without
the approval of holders of the Preferred
 
                                       90
<PAGE>
Stock, we may issue shares of Senior Securities in exchange for, or the proceeds
of which are used to redeem or repurchase, all shares of Preferred Stock then
outstanding or our indebtedness.
 
DIVIDENDS
 
    Holders of Preferred Stock are entitled to receive, when, as and if declared
by our Board of Directors, out of funds legally available therefor, dividends on
the Preferred Stock at a rate per annum equal to 12.25% of the liquidation
preference per share, payable quarterly. All dividends will be cumulative,
whether or not earned or declared, on a daily basis from the Issue Date and will
be payable quarterly in arrears on January 15, April 15, July 15 and October 15
of each year, commencing January 15, 1999. On and before January 15, 2003, we
may pay dividends, at our option, in cash or in additional fully paid and
nonassessable shares of Preferred Stock having an aggregate liquidation
preference equal to the amount of such dividends. Dividends paid in additional
shares of Preferred Stock will be calculated and paid to registered holders to
the nearest whole share. We may pay dividends in cash during the period on or
before January 15, 2003 on the Senior Preferred Stock only if we also pays
dividends in cash on the Preferred Stock during such period.
 
    The Depository Trust Company ("DTC") will not permit the allocation of
fractional shares. Consequently, payments made to Cede & Co. (as nominee for
DTC) will include cash in lieu of fractional shares based on the liquidation
preference of the Preferred Stock. Registered holders other than Cede & Co., if
any, will continue to receive fractional shares of Preferred Stock calculated to
the fifth decimal place.
 
    After January 15, 2003, we must pay only cash dividends. However, the Senior
Note Indenture, the certificate of designation for the Senior Preferred Stock
and the credit facilities restrict our payment of cash dividends, and future
agreements may provide the same. If any dividend, or portion thereof, payable on
any dividend payment date is not declared or paid in full in cash or, on or
prior to January 15, 2003, in cash or Preferred Stock on such dividend payment
date, the amount of accrued and unpaid dividends will bear interest at the
dividend rate on the Preferred Stock, compounding quarterly, until declared and
paid in full.
 
    No full dividends may be declared or paid or funds set apart for the payment
of dividends on any Parity Securities for any period unless full cumulative
dividends shall have been or contemporaneously shall be declared and paid in
full or declared and, if payable in cash, a sum in cash shall be set apart for
such payments on the Preferred Stock. If full dividends are not so paid, the
Preferred Stock will share dividends on a pro rata basis with the Parity
Securities. No dividends may be paid or set apart for such payment on Junior
Securities (except dividends on Junior Securities in additional shares of Junior
Securities) and no Junior Securities or Parity Securities may be repurchased,
redeemed or otherwise retired nor may funds be set apart for payment with
respect thereto if full cumulative dividends shall not have been paid on the
Preferred Stock.
 
OPTIONAL REDEMPTION
 
    We may redeem the Preferred Stock (subject to contractual and other
restrictions and to the legal availability of funds) at any time on or after
January 15, 2003, at our option, in whole or in part, at the redemption prices
(expressed as a percentage of the liquidation preference thereof) set forth
below, plus an amount in cash equal to all accumulated and unpaid dividends
(including an amount in cash equal to a prorated dividend for the period from
the dividend payment date immediately prior to the redemption date to the
redemption date, but subject to the right of holders of Preferred Stock on a
record date to
 
                                       91
<PAGE>
receive dividends on a dividend payment date), if redeemed during the 12-month
period beginning January 15 of each of the years set forth below.

</TABLE>
 
    In addition, on or prior to January 15, 2001, we may redeem Preferred Stock
at a redemption price equal to 112.250% of the liquidation preference, plus an
amount in cash equal to all accumulated and unpaid dividends (including an
amount in cash equal to a prorated dividend for the period from the dividend
payment date immediately prior to the redemption date to the redemption date,
but subject to the right of holders of Preferred Stock on a record date to
receive dividends due on a dividend payment date), with the proceeds of any sale
of our common stock, but only if such redemption date occurs within 180 days
after consummation of such sale and at least 65% aggregate liquidation
preference of Preferred Stock originally issued remains outstanding after each
such redemption.
 
    We will not exercise our optional redemption rights provided in the
certificate of designation with respect to our Senior Preferred Stock unless we
contemporaneously redeems the Preferred Stock pro rata.
 
    We may not effect an optional redemption of the Preferred Stock unless prior
thereto full unpaid cumulative dividends are set apart for such payment.
 
    In the event we effect a partial redemption of Preferred Stock, we will
select the shares to be redeemed PRO RATA or by lot, as we determine, except
that we may redeem shares held by any holder of fewer than 100 shares without
regard to such pro rata redemption requirement. The Senior Note Indenture and
the credit facilities restrict our ability to redeem the Preferred Stock and
future agreements may contain similar provisions. See "Description of Certain
Indebtedness--The Senior Notes," "--The DOC Facility" and "--The DCOC Facility."
We will provide notice of redemption first-class mail to each holder's
registered address at least 30 but no more than 60 days prior to the redemption
date. If we redeem any Preferred Stock in part, the notice of redemption that
related to such Preferred Stock shall state the portion of the liquidation
preference to be redeemed. We will issue new shares of Preferred Stock having an
aggregate liquidation preference equal to the unredeemed portion in the name of
the holder thereof upon cancellation of the original Preferred Stock and, unless
we fail to pay the redemption price on the redemption date, after the redemption
date, dividends will cease to accrue on the Preferred Stock called for
redemption.
 
MANDATORY REDEMPTION
 
    We must redeem the Preferred Stock (subject to the legal availability of
funds therefor but without regard to any contractual or other restrictions with
respect thereto) in whole on January 15, 2008 (the "Mandatory Redemption Date")
at a price, payable in cash, equal to the liquidation preference thereof plus
all accumulated and unpaid dividends to the date of redemption.
 
CHANGE OF CONTROL
 
    Upon the occurrence of a Change of Control, we will be required, subject to
any contractual and other restrictions and the legal availability of funds
therefor, to make an offer (the "Change of Control Offer") to each holder of
Preferred Stock to repurchase all or any part of such holder's Preferred Stock
at a cash purchase price equal to 101% of the liquidation preference thereof,
plus an amount in cash equal to all accumulated and unpaid dividends (including
an amount in cash equal to a prorated dividend for the period from the dividend
payment date immediately prior to the date of purchase to the date of purchase)
(the "Change of Control Payment"). The Change of Control Offer must be made
within 30 days following
 
                                       92
<PAGE>
a Change of Control, must remain open for at least 30 and not more than 40 days
and must comply with the requirements of Rule 14e-1 under the Exchange Act and
any other applicable securities laws and regulations. Notwithstanding the
foregoing, we are not required to make a Change of Control Offer if any
indebtedness that was outstanding on the Closing Date would prohibit such Change
of Control Offer or any Indebtedness under the DOC Facility or the DCOC Facility
is outstanding upon the occurrence of a Change of Control until such
Indebtedness is repaid, redeemed or repurchased in full, in which case the date
on which all such Indebtedness is so repaid, redeemed or repurchased will, under
the Certificate of Designation, be deemed to be the date on which such Change of
Control shall have occurred.
 
    Our Board of Directors cannot waive any of the provisions in the Certificate
of Designation relating to a purchase upon a Change of Control. We could, in the
future, enter into certain transactions, including certain recapitalizations,
that would not constitute a Change of Control, but would increase the amount of
indebtedness outstanding at such time. If a Change of Control were to occur, we
would be obligated to offer to repurchase all Indebtedness outstanding on the
Closing Date which would prohibit a Change of Control Offer prior to making an
offer to repurchase Preferred Stock, and there can be no assurance that we would
have sufficient funds to pay the purchase price for all Preferred Stock that we
would be required to purchase. In the event that we were required to purchase
outstanding Preferred Stock pursuant to a Change of Control Offer, we expect
that we would need to seek third-party financing to the extent we do not have
available funds to meet our purchase obligations. However, there can be no
assurance that we would be able to obtain such financing. In addition, our
ability to purchase the Preferred Stock may be limited by other then-existing
agreements and by restrictions imposed by Oklahoma law.
 
LIQUIDATION PREFERENCE
 
    Upon our voluntary or involuntary liquidation, dissolution or winding-up,
holders of Preferred Stock will be entitled to be paid, out of our assets
available for distribution, $1,000 per share, plus an amount in cash equal to
accumulated and unpaid dividends thereon to the date fixed for liquidation,
dissolution or winding-up (including an amount equal to a prorated dividend for
the period from the last dividend payment date to the date fixed for
liquidation, dissolution or winding-up), before any distribution is made on any
Junior Securities, including, without limitation, our Class A Preferred Stock,
Class D Preferred Stock, Class E Preferred Stock, Class F Preferred Stock, Class
G Preferred Stock, Class H Preferred Stock and our Common Stock. However, in a
bankruptcy proceeding commenced by or against us under the U.S. Bankruptcy Code,
the claim of a holder of Preferred Stock may be limited to the sum of
 
    - the initial offering price, and
 
    - that portion of the difference between the liquidation preference and the
      initial offering price not held to be the equivalent of "unmatured
      interest" for purposes of the U.S. Bankruptcy Code.
 
    If, upon our voluntary or involuntary liquidation, dissolution or
winding-up, the amounts payable with respect to the Preferred Stock and all
other Parity Securities are not paid in full, holders of the Preferred Stock and
the Parity Securities will share equally and ratably in any distribution of our
assets in proportion to the full liquidation preference and accumulated and
unpaid dividends to which each is entitled. After payment of the full amount of
the liquidation preferences and accumulated and unpaid dividends to which they
are entitled, the holders of Preferred Stock will not be entitled to any further
participation in any distribution of our assets. However, a merger,
consolidation or sale of all or substantially all of our assets that complies
with the provisions described below under "--Consolidation, Merger and Sale of
Assets" will not be deemed to be a liquidation, dissolution or winding-up of us.
 
    The Certificate of Designation does not contain any provision requiring that
we set aside funds to protect the liquidation preference of the Preferred Stock,
although such liquidation preference will be substantially in excess of the par
value of such Preferred Stock. In addition, we are not aware of any provision of
Oklahoma law or any controlling decision of the courts of the State of Oklahoma
(our state of incorporation) that requires a restriction upon our surplus solely
because the liquidation preference of the
 
                                       93
<PAGE>
Preferred Stock will exceed its par value. Consequently, there will be no
restriction upon or surplus solely because the liquidation preference of the
Preferred Stock will exceed the par value and there will be no remedies
available to holders of the Preferred Stock before or after the payment of any
dividend, other than in connection with our liquidation, solely by reason of the
fact that such dividend would reduce our surplus to an amount less than the
difference between the liquidation preference of the Preferred Stock and its par
value.
 
VOTING RIGHTS
 
    The holders of Preferred Stock have no voting rights with respect to general
corporate matters except as provided by law or as set forth in the Certificate
of Designation. The Certificate of Designation provides that if
 
    (a) dividends on the Preferred Stock are in arrears and unpaid (and, with
respect to dividends that become payable after January 15, 2003, are not paid in
cash) for four quarterly periods (whether or not consecutive),
 
    (b) we fail to discharge any redemption obligation with respect to the
Preferred Stock,
 
    (c) we fail to make an offer to purchase (and complete such purchase of) all
of the outstanding shares of Preferred Stock following a Change of Control, if
such offer to purchase is required by the provisions set forth above under the
caption "--Change of Control,"
 
    (d) a breach or violation of the provisions described under the caption
"--Covenants" occurs and such breach or violation continues for a period of 30
consecutive days or more after we receive notice thereof by holders of 25% or
more of the shares of Preferred Stock then outstanding,
 
    (e) there occurs with respect to any issue or issues of our indebtedness
and/or any significant subsidiary having an outstanding principal amount of $10
million or more in the aggregate for all such issues of ours and/or any
Significant Subsidiary, whether such Indebtedness now exists or shall hereafter
be created,
 
    (f) an event of default that has caused the holder thereof to declare such
Indebtedness to be 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
 
    (g) 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,
 
then the number of directors constituting the Board of Directors will be
adjusted to permit the holders of the majority of the then outstanding shares of
Preferred Stock, voting separately as a class, to elect two directors. Such
voting rights and the term of office of such elected directors will continue
until such time as all dividends in arrears on the Preferred Stock are paid in
full (and, in the case of dividends payable after January 15, 2003, paid in
cash) and any failure, breach or default referred to in clause (b), (c), (d) or
(e) is remedied, at which time the term of any directors elected pursuant to the
provisions of this paragraph shall terminate. For the purpose of determining the
number of quarterly periods for which accrued dividends have not been paid, any
accrued and unpaid dividend that is subsequently paid shall not be treated as
unpaid. Each such event described in clauses (a) through (e) above is referred
to herein as a "Voting Rights Triggering Event." Within 15 days of the time we
become aware of the occurrence of any default referred to in clause (d) or (e)
above, we shall give written notice thereof to holders of the Preferred Stock.
 
    The Certificate of Designation provides that, upon the occurrence of a
Voting Rights Triggering Event, the number of directors constituting the Board
of Directors will be increased by two directors, whom the holders of Preferred
Stock are entitled to elect. Whenever the right of the holders of Preferred
Stock to elect directors shall cease, the number of directors constituting the
Board of Directors will be
 
                                       94
<PAGE>
restored to the number of directors constituting the Board of Directors prior to
the time or event that entitled the holders of Preferred Stock to elect
directors.
 
    Any vacancy occurring in the office of a director elected by the holders of
Preferred Stock may be filled by the remaining director elected by such holders
unless and until such vacancy shall be filled by such holders.
 
    The Certificate of Designation provides that, except as stated above under
"--Ranking," we will not authorize any class of Senior Securities without the
affirmative vote or consent of the holders of at least a majority of the shares
of Preferred Stock then outstanding, voting or consenting, as the case may be,
separately as one class. The Certificate of Designation also provides that we
may not amend the Certificate of Designation so as to affect adversely the
specific rights, preferences, privileges or voting rights of holders of the
Preferred Stock, or authorize the issuance of any additional shares of Preferred
Stock, other than to pay dividends in kind, without the affirmative vote or
consent of the holders of at least a majority of the outstanding shares of
Preferred Stock, voting or consenting, as the case may be, separately as one
class. The holders of at least a majority of the outstanding shares of Preferred
Stock, voting or consenting, as the case may be, separately as one class, may
also waive compliance with any provision of the Certificate of Designation. The
Certificate of Designation also provides that, except as set forth above,
 
    - the creation, authorization or issuance of any shares of Junior
      Securities, Parity Securities or Senior Securities, or
 
    - the increase or decrease in the amount of authorized capital stock of any
      class, including any preferred stock
 
shall not require the consent of the holders of Preferred Stock and shall not be
deemed to affect adversely the rights, preferences, privileges or voting rights
of the holders of Preferred Stock.
 
    Under Oklahoma law, the holders of Preferred Stock will be entitled to vote
as a class upon a proposed amendment to the Certificate of Incorporation,
whether or not entitled to vote thereon by the Certificate of Incorporation, if
the amendment would increase or decrease the par value of the shares of such
class, or alter or change the powers, preferences or special rights of the
shares of such class so as to affect them adversely.

           any Disqualified Stock or any options, warrants or other rights that
           are redeemable at the option of the holder, or are required to be
           redeemed, prior to the Mandatory Redemption Date), plus

           Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each
           case as provided in the definition of "Investment"). Not to exceed,

    - after giving pro forma effect to any such purchase the Consolidated
      Leverage Ratio would be less than 7.5 to 1, and
 
    - if the event triggering the exercisability of the put rights constitutes a

terms of any agreement under which such shares of Junior Securities or options
were issued, but only if the aggregate consideration paid for such purchase,

    LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
  SUBSIDIARIES
 
    Dobson and its Restricted Subsidiaries will not, create or otherwise cause
or permit to exist or become effective any consensual encumbrance or restriction
of any kind on the ability of any Restricted Subsidiary to:
 
    - pay dividends or make any other distributions permitted by applicable law
      on any Capital Stock of such Restricted Subsidiary owned by Dobson or any
      other Restricted Subsidiary,
 
    - pay any Indebtedness owed to Dobson or any other Restricted Subsidiary,
 
    - make loans or advances to Dobson or any other Restricted Subsidiary or
 
    - transfer any of its property or assets to Dobson or any other Restricted
      Subsidiary.
 
However, the prohibition does not apply to any encumbrances or restrictions:
 
    (1) existing on the Closing Date in the certificate of designation for the
       Senior Preferred Stock, the Bank Facility Agreement, the Senior Note
       Indenture or any other agreements in effect on the Closing Date or in the
       Certificate of Designation, and any amendments, extensions, refinancings,
       renewals or replacements of such agreements; on the condition that, other
       than as contemplated in clause (4) below, the encumbrances and
       restrictions in any such amendments, extensions, refinancings, renewals
       or replacements are no less favorable in any material respect to the
       Holders than those encumbrances or restrictions that are then in effect
       and that are being extended, refinanced, renewed or replaced;
 
    (2) existing under or by reason of applicable law;
 
    (3) existing with respect to any Person or the property or assets of such
       Person acquired by Dobson or any Restricted Subsidiary, existing at the
       time of such acquisition and not incurred in contemplation thereof, which
       encumbrances or restrictions are not applicable to any Person or the
       property or assets of any Person other than such Person or the property
       or assets of such Person so acquired;
 
    (4) in the case of restrictions relating to the transfers of property,
       restrictions that;
 
           - restrict in a customary manner the subletting, assignment or
             transfer of any property or asset that is a lease, license,
             conveyance or contract or similar property or asset,
 
           - exist by virtue of any transfer of, agreement to transfer, option
             or right with respect to, or Lien on, any property or assets of
             Dobson or any Restricted Subsidiary not otherwise prohibited by the
             Certificate of Designation or
 
           - arise or in the ordinary course of business, not relating to any
             Indebtedness, and that do not, individually or in the aggregate,
             detract from the value of property or assets of Dobson or any
             Restricted Subsidiary in any manner material to Dobson or any
             Restricted Subsidiary;
 
    (5) with respect to a Restricted Subsidiary and imposed pursuant to an
       agreement that has been entered into for the sale or disposition of all
       or substantially all of the Capital Stock of, or property and assets of,
       such Restricted Subsidiary; or
 
    (6) contained in the terms of:
 
       (a) the DOC Facility Agreement or the DCOC Facility Agreement if the
           encumbrances and restrictions that would prevent dividends or
           distributions to Dobson to permit it to pay
 
                                      114
<PAGE>
           dividends on the Preferred Stock or Exchange Debentures apply only
           prior to January 15, 2003 or upon a default other than a breach of
           warranty but only if:
 
           - the event of default is not a payment default, bankruptcy default
             or loss of a material license or cellular system, and
 
           - restriction will terminate 180 days after the occurrence of the
             event of default, and
 
           - the financial covenants which create the encumbrance or restriction
             are no less favorable to Dobson or the Subsidiaries than the
             covenants contained in the committment letter for the DOC Facility
             and the DCOC Facility, or
 
       (b) any Indebtedness, or any agreement creating Indebtedness, of a
           Restricted Subsidiary if:
 
           - the indebtedness or restriction applies only if there is a payment
             default with respect to a financial covenant, and
 
           - the indebtedness or restriction is not materially more
             disadvantageous to holders of Preferred Stock than is customary in
             comparable financings, and
 
           - Dobson determines that the encumbrance or restriction will not
             materially affect the ability to pay dividends on the Preferred
             Stock or interest on the Exchange Debentures.
 
    Dobson and its Restricted Subsidiaries are not precluded from:
 
           - creating, incurring, assuming or permitting to exist any Liens
             otherwise permitted under the "Limitation on Liens" covenant, or
 
           - restricting the sale of their assets that secure Indebtedness of
             Dobson or its Restricted Subsidiaries.
 
    LIMITATION ON THE ISSUANCE AND SALE OF CAPITAL STOCK OF RESTRICTED
  SUBSIDIARIES
 
    Dobson and its Restricted Subsidiaries will not sell, directly or
indirectly, any shares of Capital Stock of a Restricted Subsidiary, including
options, warrants or other rights to purchase shares of such Capital Stock,
except:
 
    (1) to Dobson or a Wholly Owned Restricted Subsidiary;
 
    (2) issuances of director's qualifying shares or sales to foreign nationals
       of shares of Capital Stock of foreign Restricted Subsidiaries, to the
       extent required by applicable law;
 
    (3) if, immediately after giving effect to such issuance or sale, such
       Restricted Subsidiary would no longer constitute a Restricted Subsidiary.
       However, any remaining Investment in such Person after giving effect to
       the issuance or sale would have been permitted to be made under the
       "Limitation on Restricted Payments" covenant, if made on the date of such
       issuance or sale; and
 
    (4) sales of Common Stock of a Restricted Subsidiary but only if the assets
       of such Restricted Subsidiary consist solely of assets relating to the
       Dobson's PCS or resale business.
 
    LIMITATION ON TRANSACTIONS WITH STOCKHOLDERS AND AFFILIATES
 
    Dobson and its Restricted Subsidiaries will not, directly or indirectly,
engage in 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 Dobson or any Affiliate of Dobson or any Restricted Subsidiary,
except upon fair and reasonable terms no less favorable to Dobson or such
Restricted Subsidiary than could be obtained in a comparable arm's-length
transaction with a Person that is not such a holder or an Affiliate.
 
                                      115
<PAGE>
    The above limitation does not not apply to:
 
    (1) transactions
 
       (a) approved by a majority of the disinterested members of the Board of
           Directors, or
 
       (b) for which Dobson or a Restricted Subsidiary delivers to the Transfer
           Agent a written opinion of a nationally recognized investment banking
           firm stating that the transaction is fair to Dobson or such
           Restricted Subsidiary from a financial point of view;
 
    (2) any transaction solely between Dobson and any of its Wholly Owned
       Restricted Subsidiaries or solely between Wholly Owned Restricted
       Subsidiaries;
 
    (3) the payment of reasonable and customary regular fees to directors of
       Dobson who are not employees of Dobson;
 
    (4) any payments or other transactions pursuant to any tax-sharing agreement
       between Dobson and any other Person with which Dobson files a
       consolidated tax return or with which Dobson is part of a consolidated
       group for tax purposes; or
 
    (5) any Restricted Payments not prohibited by the "Limitation on Restricted
       Payments" covenant.
 
Any transaction covered by the first paragraph of this "Limitation on
Transactions with Stockholders and Affiliates" covenant and not covered by
clauses (2) through (5) of this paragraph, the aggregate amount of which exceeds
$2 million in value, must be approved or determined to be fair by a majority of
the disinterested members of the Board of Directors.
 
    LIMITATIONS ON SENIOR PREFERRED STOCK
 
    Dobson will not
 
    - exchange any Preferred Stock for Senior Exchange Debentures unless it will
      have previously exchanged, or will contemporaneously exchange, all of the
      Preferred Stock for Exchange Debentures, or
 
    - redeem any Preferred Stock unless it will contemporaneously redeem a pro
      rata portion of the Preferred Stock.
 
SEC REPORTS AND REPORTS TO HOLDERS
 
    Whether or not we are required to file reports with the SEC, for so long as
any Preferred Stock is outstanding, we will file with the SEC all reports and
other information as it would be required to file with the SEC by Section 13(a)
or 15(d) under the Exchange Act if it were subject thereto. We shall supply the
Transfer Agent and each Holder or shall supply to the Transfer Agent for
forwarding to each such Holder, without cost to such Holder, copies of such
reports and other information.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
    We will not consolidate or merge with, or sell, lease or otherwise dispose
of all or substantially all of our property and assets in one transaction or a
series of related transactions to any Person or permit any Person to merge with
or into us unless:
 
    (1) the resulting, surviving or transferee Person ("the Successor Company")
       will be a person organized and existing under the laws of the United
       States of America, or, any state or jurisdiction thereof and the
       Preferred Stock shall be converted into or exchanged for and shall become
       shares of the Successor Company having substantially the same powers,
       preferences and relative participating, optional or other special rights
       and the qualifications, limitations or restrictions that the Preferred
       Stock had immediately prior to such transaction;
 
                                      116
<PAGE>
    (2) immediately after giving effect to such transaction, no Voting Rights
       Triggering Event, or an event which with the giving of notice or the
       passage of time, or both, would become a Voting Rights Triggering Event,
       shall have occurred and be continuing;
 
    (3) immediately after giving effect to such transaction on a pro forma
       basis, we, or the Successor Company or resulting company, as the case may
       be, shall have a Consolidated Net Worth equal to or greater than our
       Consolidated Net Worth immediately prior to such transaction;
 
    (4) immediately after giving effect to such transaction on a pro forma basis
       we, or the Successor Company or resulting company, as the case may be,
       could Incur at least $1.00 of Indebtedness under the first paragraph of
       the "Limitation on Indebtedness" covenant. However, this clause (4) shall
       not apply to a consolidation or merger with or into a Wholly Owned
       Restricted Subsidiary with a positive net worth. In connection with any
       such merger or consolidation, no consideration other than common stock in
       the surviving Person or our Common Stock shall be issued or distributed
       to our stockholders; and
 
    (5) We deliver to the Transfer Agent an Officers' Certificate, attaching the
       arithmetic computations to demonstrate compliance with clauses (3) and
       (4), and Opinion of Counsel, in each case stating that such
       consolidation, merger or transfer complies with this provision and that
       all conditions precedent provided for herein relating to such transaction
       have been complied with. Clauses (3) and (4) above will not apply if, in
       the good faith determination of our Board of Directors, the principal
       purpose of the transaction is to change our state of incorporation and
       the transaction does not have as one of its purposes the evasion of the
       foregoing limitations.
 
EXCHANGE
 
    Subject to the "Limitations on Senior Preferred Stock" covenant and, the
legal availability of funds, we may exchange all of the outstanding Preferred
Stock, including any Preferred Stock issued as payment for dividends, for
Exchange Debentures, subject to the conditions set forth below. Presently, the
exchange of the Preferred Stock for Exchange Debentures would be restricted by
covenants in the Senior Note Indenture, the DOC Facility Agreement and the DCOC
Facility Agreement. We can give you no assurance that the conditions in such
covenants for the exchange of Preferred Stock for Exchange Debentures will be
satisfied or that the exchange will occur or that future Indebtedness of the
Company would not also restrict an exchange. See "Description of Certain
Indebtedness--The Senior Notes," "--The DOC Facility" and "--The DCOC Facility."
 
    In order to effect such exchange, we shall
 
    - if necessary to satisfy the condition set forth in clause (b) in the
      following paragraph based upon the written advice of our counsel, file a
      registration statement with the SEC relating to the exchange, and
 
    - if a registration statement is filed with the SEC, use its best efforts to
      cause such registration statement to be declared effective as soon as
      practicable by the SEC unless the opinion referred to in clause (b) in the
      following paragraph shall have been subsequently delivered.
 
    In order to effectuate the exchange, we shall send a written notice of
exchange by mail to each holder of record of Preferred Stock. This notice shall
state:
 
    (1) that we are exchanging the Preferred Stock into Exchange Debentures
       pursuant to the Certificate of Designation, and
 
    (2) on the date fixed for exchange (the "Exchange Date"), if the conditions
       set forth in clauses (a) through (e) below are satisfied and the exchange
       is permitted under our then outstanding
 
                                      117
<PAGE>
       indebtedness, we shall issue Exchange Debentures in exchange for the
       Preferred Stock as provided in the next paragraph. However, on the
       Exchange Date:
 
       (a) we shall have legally available funds sufficient for the exchange
           including under Oklahoma law;
 
       (b) a registration statement relating to the Exchange Debentures shall
           have been declared effective under the Securities Act prior to such
           exchange and shall continue to be effective on the Exchange Date or
           we shall have obtained a written opinion of counsel that an exemption
           from the registration requirements of the Securities Act is available
           for such exchange and that upon receipt of such Exchange Debentures
           each holder of an Exchange Debenture that is not our Affiliate will
           not be subject to any restrictions imposed by the Securities Act upon
           the resale of such Exchange Debenture, and we have relied upon such
           exemption for such exchange;
 
       (c) the Exchange Debenture Indenture and the trustee thereunder shall
           have been qualified under the Trust Indenture Act
 
       (d) immediately after giving effect to such exchange, no Default or Event
           of Default would exist under the Exchange Debenture Indenture; and
 
       (e) we shall have delivered to the Trustee under the Exchange Debenture
           Indenture a written opinion of counsel regarding the satisfaction of
           the conditions set forth in clauses (a), (b) and (c).
 
    If the issuance of the Exchange Debentures is not permitted on the Exchange
Date or any of the conditions set forth in clauses (a) through (e) of the
preceding sentence are not satisfied on the Exchange Date, we shall use its best
efforts to satisfy such conditions and effect such exchange as soon as
practicable.
 
    Upon any exchange, holders of outstanding Preferred Stock will be entitled
to receive a principal amount of Exchange Debentures for Preferred Stock, the
liquidation preference of which, plus the amount of accumulated and unpaid
dividends, including a prorated dividend for the period from the immediately
preceding dividend payment date to the Exchange Date, with respect to which,
equals such principal amount. However, we may pay cash for any or all accrued
and unpaid dividends in lieu of issuing Exchange Debentures in respect of such
dividends. The Exchange Debentures will be issued in registered form, without
coupons, in principal amounts of $1,000 and integral multiples thereof to the
extent practicable, and will also be issued in principal amounts less than
$1,000 so that each holder of Preferred Stock will receive certificates
representing the entire principal amount of Exchange Debentures to which its
Preferred Stock entitle it. Subject to restrictions in the Senior Note
Indenture, the DOC Facility Agreement, the DCOC Facility Agreement and any of
its other then-existing Indebtedness, we may pay cash in lieu of issuing an
Exchange Debenture in a principal amount less than $1,000. On and after the date
of exchange, dividends will cease to accrue on the outstanding Preferred Stock,
and all rights of the holders of Preferred Stock, except the right to receive
the Exchange Debentures, cash equal to the accrued and unpaid dividends to the
Exchange Date, and, if we so elect, cash in lieu of any Exchange Debenture which
is in an amount that is less than $1,000, will terminate. The person entitled to
receive the Exchange Debentures issuable upon such exchange will be treated for
all purposes as the registered holder of such Exchange Debentures.
 
    We will comply with the provisions of Rule 13e-4 promulgated pursuant to the
Exchange Act in connection with any exchange, to the extent applicable.
 
PREFERRED STOCK EXCHANGE OFFER REGISTRATION
 
    We have agreed to use our best efforts, at our cost, to file and cause to
become effective a registration statement with respect to a registered offer to
exchange the Old Shares for the New Shares in the exchange
 
                                      118
<PAGE>
offer. When that registration statement is declared effective, we will offer the
New Shares in return for surrender of the Old Shares. The exchange offer must
remain open for not less than 20 business days after the date that notice of the
exchange offer is mailed to holders of the Old Shares. In the event that
applicable interpretations of the staff of the SEC do not permit us to effect
such an exchange offer, or under certain other circumstances, we shall, at our
cost, use our best efforts to cause to become effective a shelf registration
statement with respect to resales of the Old Shares and to keep such
registration statement effective until the expiration of the time period
referred to in Rule 144(k) under the Securities Act after the Issue Date. In the
event of such shelf registration, we shall provide to each holder of Preferred
Stock copies of the prospectus, notify each holder of Preferred Stock when a
registration statement for the Preferred Stock has become effective and take
certain other actions as are required to permit resales of the Preferred Stock.
 
    If the exchange offer is not consummated and a shelf registration statement
is not declared effective on or prior to 180 days after the Issue Date,
additional dividends will accrue, at an annual rate of .5% of the liquidation
preference thereof, on the Old Shares from the date that is 180 days after the
Issue Date, payable in additional shares of Preferred Stock quarterly in arrears
on each January 15, April 15, July 15 and October 15, commencing July 15, 1999,
until the exchange offer is consummated or such shelf registration statement is
declared effective. Holders of Old Shares who do not participate in the exchange
offer may thereafter hold a less liquid security. Holders of Old Shares will not
be named as selling securityholders in a exchange offer registration statement.
 
PREFERRED STOCK BOOK-ENTRY; DELIVERY AND FORM
 
    Preferred Stock will be represented by a single, permanent global Preferred
Stock certificate, in definitive, fully registered form (the "Restricted Global
Preferred Stock Certificate") and will be deposited with a custodian for DTC and
registered in the name of a nominee of DTC. The Restricted Global Preferred
Stock Certificate (and any Preferred Stock issued in exchange therefor) will be
subject to certain restrictions on transfer set forth therein and will bear the
legend regarding such restrictions set forth under "Notice to Investors." The
Preferred Stock is not issuable in bearer form.
 
THE GLOBAL PREFERRED STOCK CERTIFICATE
 
    Upon the issuance of the Restricted Global Preferred Stock Certificate, DTC
or its custodian will credit, on its internal system, the respective liquidation
preference of the individual beneficial interests represented by such Restricted
Global Preferred Stock Certificate, to the accounts of persons who have accounts
with such depositary. Such accounts initially will be designated by or on behalf
of the Placement Agents. Ownership of beneficial interests in a Restricted
Global Preferred Stock Certificate will be limited to persons who have accounts
with DTC ("participants") or persons who hold interests through participants.
Ownership of beneficial interests in the Restricted Global Preferred Stock
Certificate will be shown on, and the transfer of that ownership will be
effected only through, records maintained by DTC or its nominee (with respect to
interests of participants) and the records of participants (with respect to
interests of persons other than participants). Qualified Institutional Buyers
may hold their interests in the Restricted Global Preferred Stock Certificate
directly through DTC if they are participants in such system, or indirectly
through organizations that are participants in such system.
 
    So long as DTC, or its nominee, is the registered owner or holder of a
Restricted Global Preferred Stock Certificate, DTC or such nominee, as the case
may be, will be considered the sole owner or holder of the Preferred Stock
represented by such Restricted Global Preferred Stock Certificate for all
purposes under the Certificate of Designation and the Preferred Stock. No
beneficial owner of an interest in a Restricted Global Preferred Stock
Certificate will be able to transfer that interest except in accordance with
DTC's applicable procedures, in addition to those provided for under the
Certificate of Designation.
 
                                      119
<PAGE>
    Payments made with respect to a Restricted Global Preferred Stock
Certificate will be made to DTC or its nominee, as the case may be, as the
registered owner thereof. Neither the Company nor the Placement Agents will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Restricted
Global Preferred Stock Certificate or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.
 
    We expect that DTC or its nominee, upon receipt of any payments made with
respect to the Restricted Global Preferred Stock Certificate, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the amount of such Restricted Global
Preferred Stock Certificate as shown on the records of DTC or its nominee. We
also expect that payments by participants to owners of beneficial interests in
such Restricted Global Preferred Stock Certificates held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in the names of nominees for such customers. Such payments will be the
responsibility of such participants.
 
    Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds.
 
    We understand that DTC will take any action permitted to be taken by a
holder of Preferred Stock (including the presentation of Preferred Stock for
exchange as described below) only at the direction of one or more participants
to whose account the interests in the Restricted Global Preferred Stock
Certificate are credited and only in respect of such portion of the aggregate
liquidation preference of Preferred Stock as to which such participant or
participants has or have given such direction.
 
    We understand that DTC is a limited purpose trust company organized under
the laws of the State of New York, a "banking organization" within the meaning
of New York Banking Law, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the Uniform Commercial Code and a "Clearing
Agency" registered pursuant to the provisions of Section 17A of the Exchange
Act. DTC was created to hold securities for its participants and facilitate the
clearance and settlement of securities transactions between participants through
electronic book-entry changes in accounts of its participants. Indirect access
to the DTC system is available to others such as banks, brokers, dealers and
trust companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly ("indirect participants").
 
    Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in the Restricted Global Preferred Stock
Certificate among participants of DTC, it is under no obligation to perform or
continue to perform such procedures, and such procedures may be discontinued at
any time. Neither the Initial Purchaser nor we will have any responsibility for

                     DESCRIPTION OF THE EXCHANGE DEBENTURES
 
    In the event we issue the Exchange Debentures, we will issue them under the
Exchange Debenture Indenture between the United States Trust Company of New
York, as trustee (the "Trustee") and ourselves, a copy of the form of which we
make available upon request. The terms of the Exchange Debentures include those
stated in the Exchange Debenture Indenture and those made part of the Exchange
Debenture Indenture by reference to the Trust Indenture Act.
 
    The following summary of certain provisions of the Exchange Debenture
Indenture does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, the Trust Indenture Act and to all of the
provisions of the Exchange Debenture Indenture, including the definitions of
certain terms therein and those terms made a part of the Exchange Debenture
Indenture by reference to the Trust Indenture Act. The definitions of certain
terms used in the Exchange Debentures and the Exchange Debenture Indenture and
in the following summary are set forth below under "--Certain Definitions." In
this description, "Dobson" or "Dobson Communications" refers only to Dobson
Communications Corporation and not to any of our subsidiaries.
 
GENERAL
 
    The Exchange Debentures will be our unsecured obligations and, will be
initially limited in aggregate principal amount to the aggregate liquidation
preference of the Preferred Stock (including any Preferred Stock issued in
payment of dividends), plus accrued and unpaid dividends, on the date of
exchange of the Preferred Stock into Exchange Debentures (plus any additional
Exchange Debentures issued in lieu of cash interest as described herein). We
will issue the Exchange Debentures in fully registered form only in
denominations of $1,000 and integral multiples thereof (other than as described
in "Description of Preferred Stock--Exchange" or with respect to additional
Exchange Debentures issued in lieu of cash interest as described herein). The
Exchange Debentures will be our senior subordinated obligations, subordinated to
all of our existing and future Senior Indebtedness and senior to all of our
subordinated obligations.
 
    Principal of, premium, if any, and interest on the Exchange Debentures will
be payable, and the Exchange Debentures may be presented for registration of
transfer or exchange, at the office of the Paying Agent and Registrar. At our
option, interest, to the extent paid in cash, may be paid by check mailed to the
registered address of holders of the Exchange Debentures as shown on the
register for the Exchange Debentures. The Trustee will initially act as Paying
Agent and Registrar. We may change any Paying Agent and Registrar without prior
notice to Holders of the Exchange Debentures. Holders of the Exchange Debentures
must surrender Exchange Debentures to the Paying Agent to collect principal
payments.
 
    The Exchange Debentures will mature on January 15, 2008. Each Exchange
Debenture will bear interest at the same rate in effect with respect to the
Preferred Stock on the date we issue the Exchange Debentures from the Exchange
Debenture Issue Date or from the most recent interest payment date to which
interest has been paid or provided for. Interest will be payable semi-annually
in cash, or, on or prior to January 15, 2003, at our option, in additional
Exchange Debentures, in arrears on each of January 15 and July 15 commencing
with the first such date after the issue date of the Exchange Debentures. We may
pay dividends in cash during the period on or before January 15, 2003 on the
exchange debentures which may be issued upon exchange of the Senior Preferred
Stock only if it also pays interest in cash on the Exchange Debentures during
such period. Interest on the Exchange Debentures will be computed on the basis
of a 360-day year of twelve 30-day months and the actual number of days elapsed.
 
    Because of our option through January 15, 2003 to pay interest on the
Exchange Debentures by issuing additional Exchange Debentures, any Exchange
Debentures we issue prior to that date will be treated as issued with original
issue discount unless under special rules for interest holidays the amount of
original issue discount is treated as minimal. See "Federal Income Tax
Considerations."
 
                                      121
<PAGE>
    We may, subject to the covenants described below under "Covenants" and
applicable law, issue additional Exchange Debentures under the Exchange
Debenture Indenture. Those Exchange Debentures we issue in exchange for
Preferred Stock and any additional Exchange Debentures we issue subsequently
would be treated as a single class for all purposes under the Exchange Debenture
Indenture.
 
SUBORDINATION
 
    The Exchange Debentures will be our senior subordinated Indebtedness of the
Company, subordinated to the prior payment when due of the principal of, and
premium, if any, and accrued and unpaid interest on, all of our existing and
future Senior Indebtedness and senior to the prior payment when due of the
principal of, and premium, if any, and accrued and unpaid interest on, all of
our subordinated Indebtedness.
 
    Upon
 
    (a) any distribution to our creditors in the event of our liquidation or
       dissolution or in a bankruptcy, reorganization, insolvency, receivership
       or similar proceeding relating to us or our property or
 
    (b) an assignment for the benefit of creditors or any marshalling of our
       assets and liabilities, the holders of Senior Indebtedness will be
       entitled to receive payment in full of all obligations due in respect of
       such Senior Indebtedness (including interest after the commencement of
       any such proceeding at the rate specified in the applicable Senior
       Indebtedness) before holders of the Exchange Debentures will be entitled
       to receive any payment with respect to the Exchange Debentures. Until all
       obligations with respect to Senior Indebtedness are paid in full, any
       distribution to which holders of the Exchange Debentures would be
       entitled will be made to holders of Senior Indebtedness. Notwithstanding
       the foregoing, holders of the Exchange Debentures may receive securities
       that are subordinated, at least to the same extent as the Exchange
       Debentures, to Senior Indebtedness and any securities issued in exchange
       for Senior Indebtedness.
 
    In addition, we may not make any payment upon or in respect of the Exchange
Debentures (except in such subordinated securities) if
 
    (a) a default in the payment of any principal, premium, if any, interest or
       other obligations with respect to any Designated Senior Indebtedness
       occurs and is continuing beyond any applicable grace period (whether upon
       maturity, as a result of acceleration or otherwise) or
 
    (b) any other default occurs and is continuing with respect to any
       Designated Senior Indebtedness that permits holders of such Designated
       Senior Indebtedness to accelerate its maturity, and the Company and the
       Trustee receive a notice of such default (a "Payment Blockage Notice")
       from the holders, or from the trustee, agent or other representative of
       the holders, of any such Designated Senior Indebtedness. Payments on the
       Exchange Debentures may and shall be resumed upon the earlier of
 
       (1) the date upon which the default is cured or waived or
 
       (2) in the case of a default referred to in clause (b) above, 179 days
           after the date on which the applicable Payment Blockage Notice is
           received, unless the maturity of any Designated Senior Indebtedness
           has been accelerated. No new period of payment blockage may be
           commenced within 360 days after the receipt by the Trustee of any
           prior Payment Blockage Notice. No nonpayment default that existed or
           was continuing on the date of delivery of any Payment Blockage Notice
           to the Trustee shall be, or be made, the basis for a subsequent
           Payment Blockage Notice unless such default shall have been cured or
           waived for a period of not less than 180 days.
 
                                      122
<PAGE>
    The Exchange Debenture Indenture will further require that we promptly
notify holders of Senior Indebtedness if payment on the Exchange Debentures is
accelerated because of an Event of Default.
 
    As a result of the subordination provisions described above, in the event of
a liquidation or insolvency, Holders of the Exchange Debentures may recover less
ratably than other creditors of ours. We are expected to incur substantial
amounts of additional indebtedness in the future.
 
OPTIONAL REDEMPTION
 
    We may redeem the Exchange Debentures at any time on or after January 15,
2003, at our option, in whole or in part, upon not less than 30 nor more than 60
days' prior written notice mailed by first-class mail to each holder's last
address as it appears in the Security Register, at the redemption prices
(expressed as a percentage of the principal amount thereof) set forth below,
plus accrued and unpaid interest thereon to the redemption date (subject to the
right of holders of record on the relevant Regular Record Date to receive
interest due on an Interest Payment Date that is on or prior to the redemption
date), if redeemed during the 12-month period beginning January 15 of each of
the years set forth below.

</TABLE>
 
    In addition, on or prior to January 15, 2001, we may redeem Exchange
Debentures having an aggregate principal amount of up to 35% of the aggregate
liquidation preference of the Preferred Stock originally issued at a redemption
price equal to 112.250% of the principal amount thereof, plus accrued and unpaid
interest to the redemption date, with the proceeds of any sale of our common
stock, but only if such redemption occurs within 180 days after consummation of
such sale and at least 65% aggregate principal amount of Exchange Debentures
originally issued remains outstanding after each such redemption.
 
    We will agree it will not exercise its optional redemption rights with
respect to the Senior Exchange Debentures unless it contemporaneously redeems
the Exchange Debentures pro rata.
 
    In the case of any partial redemption, the Trustee will select the Exchange
Debentures for redemption in compliance with the requirements of the principal
national securities exchange, if any, on which the Exchange Debentures are
listed or, if the Exchange Debentures are not listed on a national securities
exchange, on a proportional basis, by lot or by such other method as the Trustee
in its sole discretion shall deem to be fair and appropriate; but only if no
Exchange Debenture of $1,000 in principal amount or less shall be redeemed in
part. If we redeem any Exchange Debenture in part only, the notice of redemption
relating to such Exchange Debenture shall state the portion of the principal
amount thereof to be redeemed. We will issue a new Exchange Debenture in
principal amount equal to the unredeemed portion thereof in the name of the
holder thereof upon cancellation of the original Exchange Debenture.

       constitute an Incurrence of such Indebtedness not permitted by this
       clause (2);
 
    (3) Indebtedness issued in exchange for, or the net proceeds of which are
       used to refinance or refund, then outstanding Indebtedness, other than

       (a) in case the Exchange Debentures are refinanced in part or the
           Indebtedness to be refinanced ranks equally with the Exchange
           Debentures, such new Indebtedness, by its terms or by the terms of
           any agreement or instrument pursuant to which such new Indebtedness
           is outstanding, is expressly made to rank equally with, or
           subordinate in right of payment to, the remaining Exchange
           Debentures,
 
       (b) in case the Indebtedness to be refinanced is subordinated in right of
           payment to the Exchange Debentures, such new Indebtedness, by its
           terms or by the terms of any agreement or instrument pursuant to
           which such new Indebtedness is issued or remains outstanding, is
 
                                      137
<PAGE>
           expressly made subordinate in right of payment to the Exchange
           Debentures at least to the extent that the Indebtedness to be
           refinanced is subordinated to the Exchange Debentures and
 
       (c) such new Indebtedness, determined as of the date of Incurrence of
           such new Indebtedness, does not mature prior to the Stated Maturity

             and compensation payable thereunder, or
 
       (c) arising from agreements providing for indemnification, adjustment of
           purchase price or similar obligations, or from Guarantees or letters

    exceed $30 million plus an amount not to exceed the Net Cash Proceeds
    received by Dobson after the Closing Date from the issuance and sale of its
    Capital Stock other than Disqualified Stock to a Person that is not a
    Subsidiary of Dobson, except to the extent such Net Cash Proceeds are used
    to Incur Indebtedness outstanding pursuant to clause (8) of the "Limitation
    on Indebtedness" covenant or to make Restricted Payments pursuant to clause
    (C)(2) of the first paragraph, or clause (2) or (3) of this paragraph, of
    the "Limitation on Restricted Payments" covenant; or (12) the distribution
    on or with respect to the holders of Dobson's Capital Stock of the Capital
    Stock of Logix; on the condition that, except in the case of clauses (1) and
    (3), no Default or Event of Default shall have occurred and be continuing or
    occur as a consequence of the actions or payments set forth therein.
 
    Each Restricted Payment that is permitted pursuant to as provided in the
preceding paragraph (other than the Restricted Payment referred to in clause (2)
thereof and an exchange of Capital Stock for Capital Stock or Indebtedness
referred to in clause (3) or (4) thereof), and the Net Cash Proceeds from any
issuance of Capital Stock referred to in clauses (3), (4), and (11) shall be
included in calculating whether the conditions of clause (C) of the first
paragraph of this "Limitation on Restricted Payments" covenant have been met
with respect to any subsequent Restricted Payments. In the event the proceeds of
an issuance of Capital Stock of Dobson are used for the redemption, repurchase
or other acquisition of the Exchange Debentures, or Indebtedness that is PARI
PASSU with the Exchange Debentures, then the Net Cash Proceeds of such issuance
shall be included in clause (C) of the first paragraph of this "Limitation on
Restricted Payments" covenant only to the extent such proceeds are not used for
such redemption, repurchase or other acquisition of Indebtedness.
 
    LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
     SUBSIDIARIES
 
    Dobson and its Restricted Subsidiaries will not create or otherwise cause or
permit to exist or become effective any consensual encumbrance or restriction of
any kind on the ability of any Restricted Subsidiary to
 
    (1) pay dividends or make any other distributions permitted by applicable
       law on any Capital Stock of such Restricted Subsidiary owned by Dobson or
       any other Restricted Subsidiary,
 
    (2) pay any Indebtedness owed to Dobson or any other Restricted Subsidiary,
 
    (3) make loans or advances to Dobson or any other Restricted Subsidiary, or
 
    (4) transfer any of its property or assets to Dobson or any other Restricted
       Subsidiary.
 
    However, the prohibition does not apply to any encumbrances or restrictions:
 
    (1) existing on the Closing Date in the Bank Facility Agreement, the Senior
       Note Indenture, or any other agreements in effect on the Closing Date,
       and any amendments, extensions, refinancings, renewals or replacements of
       such agreements; provided that, other than as contemplated in clause (4)
       below, the encumbrances and restrictions in any such amendments,
       extensions,
 
                                      142
<PAGE>
       refinancings, renewals or replacements are no less favorable in any
       material respect to the Holders than those encumbrances or restrictions
       that are then in effect and that are being extended, refinanced, renewed
       or replaced;
 
    (2) existing under or by reason of applicable law;
 
    (3) existing with respect to any Person or the property or assets of such
       Person acquired by Dobson or any Restricted Subsidiary, existing at the
       time of such acquisition and not incurred in contemplation thereof, which
       encumbrances or restrictions are not applicable to any Person or the
       property or assets of any Person other than such Person or the property
       or assets of such Person so acquired;
 
    (4) in the case of clause (4) of the first paragraph of this "Limitation on
       Dividend and Other Payment Restrictions Affecting Restricted
       Subsidiaries" covenant,
 
       (a) that restrict in a customary manner the subletting, assignment or
           transfer of any property or asset that is a lease, license,
           conveyance or contract or similar property or asset,
 
       (b) existing by virtue of any transfer of, agreement to transfer, option
           or right with respect to, or Lien on, any property or assets of
           Dobson or any Restricted Subsidiary not otherwise prohibited by the
           Indenture or
 
       (c) arising or agreed to in the ordinary course of business, not relating
           to any Indebtedness, and that do not, individually or in the
           aggregate, detract from the value of property or assets of the
           Company or any Restricted Subsidiary in any manner material to Dobson
           or any Restricted Subsidiary;
 
    (5) with respect to a Restricted Subsidiary and imposed pursuant to an
       agreement that has been entered into for the sale or disposition of all
       or substantially all of the Capital Stock of, or property and assets of,
       such Restricted Subsidiary; or
 
    (6) contained in the terms of
 
       (a) the DOC Facility Agreement or the DCOC Facility Agreement, if the
           encumbrances or restrictions that would prevent payments of dividends
           or other distributions to Dobson to pay cash interest on the Exchange
           Debentures applies on or prior to January 15, 2003, or applies
           thereafter only in the event of an event of default (other than a
           breach of a representation or warranty, but only if
 
           - event of default is not a payment default, bankruptcy default or a
             loss of a material license or cellular system,
 
           - such restriction will terminate 180 days after the occurrence of
             such event of default, and
 
           - the financial covenants which create such encumbrance or
             restriction on dividends or other distributions in the DOC Facility
             Agreement or the DCOC Facility Agreement are no less favorable to
             Dobson or its Subsidiaries than the financial covenants set forth
             in the New DOC Facility Commitment Letter or the New DCOC Facility
             Commitment Letter, respectively; or
 
       (b) any Indebtedness or any agreement creating Indebtedness of a
           Restricted Subsidiary, if:
 
           - the encumbrance or restriction applies only in the event of a
             payment default or a default with respect to a financial covenant
 
           - Dobson determines the encumbrance or restriction is not materially
             more disadvantageous to the Holders of the Exchange Debentures than
             is customary in comparable financings, and
 
                                      143
<PAGE>
           - Dobson determines that any such encumbrance or restriction will not
             materially affect the Company's ability to make principal or
             interest payments on the Exchange Debentures. Dobson and its
             Restricted Subsidiaries are not precluded from
 
           - creating, incurring, assuming or suffering to exist any Liens
             otherwise permitted in the "Limitation on Liens" covenant, or
 
           - restricting the sale or other disposition of property or assets of
             Dobson or any of its Restricted Subsidiaries that secure
             Indebtedness of Dobson or any of its Restricted Subsidiaries.
 
    LIMITATION ON THE ISSUANCE AND SALE OF CAPITAL STOCK OF RESTRICTED
     SUBSIDIARIES
 
    Dobson and its Restricted Subsidiaries will not sell, directly or
indirectly, any shares of Capital Stock of a Restricted Subsidiary including
options, warrants or other rights to purchase shares of such Capital Stock
except
 
    (1) to Dobson or a Wholly Owned Restricted Subsidiary;
 
    (2) issuances of director's qualifying shares or sales to foreign nationals
       of shares of Capital Stock of foreign Restricted Subsidiaries, to the
       extent required by applicable law;
 
    (3) if, immediately after giving effect to such issuance or sale, such
       Restricted Subsidiary would no longer constitute a Restricted Subsidiary,
       but only if any Investment in such Person remaining after giving effect
       to such issuance or sale would have been permitted to be made under the
       "Limitation on Restricted Payments" covenant, if made on the date of such
       issuance or sale; and
 
    (4) sales of Common Stock of a Restricted Subsidiary but only if the assets
       of such Restricted Subsidiary consist solely of assets relating to
       Dobson's PCS or resale business and the Net Cash Proceeds, if any, of
       such sale are applied in accordance with clause (A) or (B) of the
       "Limitation on Asset Sales" covenant described below.
 
    LIMITATION ON ISSUANCES OF GUARANTEES BY RESTRICTED SUBSIDIARIES
 
    Dobson and its Restricted Subsidiaries will not guarantee, directly or
indirectly, any Indebtedness of Dobson which ranks equally with or subordinate
in right of payment to the Exchange Debentures ("Guaranteed Indebtedness"),
unless
 
    (1) such Restricted Subsidiary simultaneously executes and delivers a
       supplemental indenture to the Exchange Debenture Indenture providing for
       a Guarantee (a "Subsidiary Guarantee") of payment of the Exchange
       Debentures by such Restricted Subsidiary, and
 
    (2) such Restricted Subsidiary waives, and will not in any manner whatsoever
       claim or take the benefit or advantage of, any rights of reimbursement,
       indemnity or subrogation or any other rights against the Company or any
       other Restricted Subsidiary as a result of any payment by such Restricted
       Subsidiary under its Subsidiary Guarantee. However, that this paragraph
       shall not be applicable to any Guarantee of any Restricted Subsidiary
       that existed at the time such Person became a Restricted Subsidiary and
       was not Incurred in connection with, or in contemplation of, such Person
       becoming a Restricted Subsidiary. If the Guaranteed Indebtedness
 
       (a) ranks equally with the Exchange Debentures, then the Guarantee of
           such Guaranteed Indebtedness shall rank equally with, or be
           subordinated to, the Subsidiary Guarantee, or
 
       (b) is subordinated to the Exchange Debentures, then the Guarantee of
           such Guaranteed Indebtedness shall be subordinated to the Subsidiary
           Guarantee at least to the extent that the Guaranteed Indebtedness is
           subordinated to the Exchange Debentures.
 
                                      144
<PAGE>
    Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary may provide by its terms that it shall be automatically and
unconditionally released and discharged upon
 
    (1) any sale, exchange or transfer, to any Person not an Affiliate of
       Dobson, of all of Dobson's and each Restricted Subsidiary's Capital Stock
       in, or all or substantially all the assets of, such Restricted
       Subsidiary, which sale, exchange or transfer is not prohibited by the
       Exchange Debenture Indenture, or
 
    (2) the release or discharge of the Guarantee which resulted in the creation
       of such Subsidiary Guarantee, except a discharge or release by or as a
       result of payment under such Guarantee.
 
    LIMITATION ON TRANSACTIONS WITH STOCKHOLDERS AND AFFILIATES
 
    Dobson and its Restricted Subsidiaries will not, directly or indirectly,
engage in 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 Dobson or with any Affiliate of Dobson or any Restricted
Subsidiary, except upon fair and reasonable terms no less favorable to Dobson or
such Restricted Subsidiary than could be obtained, in a comparable arm's-length
transaction with a Person that is not such a holder or an Affiliate.
 
    The above limitation does not limit, and shall not apply to:
 
    (1) transactions
 
       (a) approved by a majority of the disinterested members of the Board of
           Directors, or
 
       (b) for which Dobson 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 Dobson or such Restricted
           Subsidiary from a financial point of view;
 
    (2) any transaction solely between Dobson and any of its Wholly Owned
       Restricted Subsidiaries or solely between Wholly Owned Restricted
       Subsidiaries;
 
    (3) the payment of reasonable and customary regular fees to directors of
       Dobson who are not employees of Dobson;
 
    (4) any payments or other transactions pursuant to any tax-sharing agreement
       between Dobson and any other Person with which Dobson files a
       consolidated tax return or with which Dobson is part of a consolidated
       group for tax purposes; or
 
    (5) 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 (2)
       through (5) of this paragraph, the aggregate amount of which exceeds $2
       million in value, must be approved or determined to be fair by a majority
       of the disinterested members of the Board of Directors.
 
    LIMITATION ON ASSET SALES
 
    Dobson and its Restricted Subsidiaries will not consummate any Asset Sale,
unless
 
    (1) the consideration received by Dobson or such Restricted Subsidiary is at
       least equal to the fair market value of the assets sold or disposed of
       and
 
    (2) 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 Dobson
or any of its Restricted Subsidiaries from one or more Asset Sales occurring on
or after the Closing Date in any period of 12
 
                                      145
<PAGE>
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 Dobson and its subsidiaries has been
filed pursuant to the "Commission Reports and Reports to Holders" covenant),
then Dobson shall or shall cause the relevant Restricted Subsidiary to
 
    (1) 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 Dobson 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 Dobson 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, Dobson and its Restricted Subsidiaries existing on the
           date of such investment, and
 
    (2) apply, no later than the end of the 12-month period referred to in
       clause (1), such excess Net Cash Proceeds, (to the extent not applied
       pursuant to clause (1)), 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 (1) 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, Dobson 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 Exchange Debentures equal to the Excess Proceeds
on such date, at a purchase price equal to 101% of the principal amount thereof,
plus, in each case, accrued interest, if any, to the Payment Date.
 
    LIMITATIONS ON SENIOR EXCHANGE DEBENTURES
 
    We will not
 
       - pay interest in cash on the Senior Exchange Debentures unless it will
         contemporaneously pay interest in cash on the Exchange Debentures or
 
       - redeem any Senior Exchange Debentures unless it will contemporaneously
         redeem a pro rata portion of the Exchange Debentures.
 
REPURCHASE OF EXCHANGE DEBENTURES UPON A CHANGE OF CONTROL
 
    We must commence, within 30 days of the occurrence of a Change of Control,
and consummate an Offer to Purchase for all Exchange Debentures 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 we will have sufficient funds available at
the time of any Change of Control to make any debt payment (including
repurchases of Exchange Debentures) required by the foregoing covenant (as well
as may be contained in other securities of ours which might be outstanding at
the time). The above covenant requiring us to repurchase the Exchange Debentures
will, unless consents are obtained, require the Company to repay all
indebtedness then outstanding which by its terms would
 
                                      146
<PAGE>
prohibit such Exchange Debenture repurchase, either prior to or concurrently
with such Exchange Debenture repurchase.
 
COMMISSION REPORTS AND REPORTS TO HOLDERS
 
    Whether or not we are required to file reports with the Commission, for so
long as any Exchange Debentures are outstanding, we will 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 Exchange Act if it
were subject thereto. We 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.
 
EVENTS OF DEFAULT
 
    The following events will be defined as "Events of Default" in the Exchange
Debenture Indenture:
 
    (1) default in the payment of principal of (or premium, if any, on) any
       Exchange Debenture when the same becomes due and payable at maturity,

       is prohibited by the provisions described above under "--Ranking";
 
    (2) default in the payment of interest on any Exchange Debenture when the

             such Indebtedness to be 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

             default;
 
    (6) any final judgment or order (not covered by insurance) for the payment
       of money in excess of $10 million in the aggregate for all such final

           - appointment of a receiver, liquidator, assignee, custodian,
             trustee, sequestrator or similar official of Dobson or any

    If an Event of Default, other than an Event of Default specified in clause
(7) or (8) above that occurs with respect to Dobson, occurs and is continuing
under the Exchange Debenture Indenture, the Trustee or the Holders of at least
25% in aggregate principal amount of the Exchange Debentures, then outstanding,
by written notice to Dobson (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 Exchange Debentures
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 on the condition that so long as the DOC Facility Agreement and the DCOC
Facility Agreement are in effect, such declaration shall not become effective
until the earlier of
 
    (1) five Business Days after the receipt of the acceleration notice by the
       agents thereunder and Dobson, and
 
    (2) acceleration of the Indebtedness under either the DOC Facility Agreement
       or the DCOC Facility Agreement. In the event of a declaration of
       acceleration because an Event of Default set forth in clause (5) 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 (5) shall be remedied or cured
       by Dobson 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 (7) or (8) above occurs with
respect to Dobson, the principal of, premium, if any, and accrued interest on
the Exchange Debentures then outstanding shall automatically 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 Exchange Debentures by written notice to Dobson and to the Trustee,
may waive all past defaults and rescind and annul a declaration of acceleration
and its consequences if
 
    (1) all existing Events of Default, other than the nonpayment of the
       principal of, premium, if any, and interest on the Exchange Debentures
       that have become due solely by such declaration of acceleration, have
       been cured or waived and
 
                                      148
<PAGE>
    (2) 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 Exchange Debentures 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 Exchange Debenture
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 Exchange Debentures 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 Exchange Debentures. A Holder may not pursue
any remedy with respect to the Exchange Debenture Indenture or the Exchange
Debentures unless:
 
    (1) the Holder gives the Trustee written notice of a continuing Event of
       Default;
 
    (2) the Holders of at least 25% in aggregate principal amount of outstanding
       Exchange Debentures make a written request to the Trustee to pursue the
       remedy;
 
    (3) such Holder or Holders offer the Trustee indemnity satisfactory to the
       Trustee against any costs, liability or expense;
 
    (4) the Trustee does not comply with the request within 60 days after
       receipt of the request and the offer of indemnity; and
 
    (5) during such 60-day period, the Holders of a majority in aggregate
       principal amount of the outstanding Exchange Debentures 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 Exchange
       Debenture to receive payment of the principal of, premium, if any, or
       interest on, such Exchange Debenture or to bring suit for the enforcement
       of any such payment, on or after the due date expressed in the Exchange
       Debentures, which right shall not be impaired or affected without the
       consent of the Holder.
 
    If a bankruptcy case is commenced by or against Dobson under the U.S.
Bankruptcy Code after the issuance of the Exchange Debentures, the claim of a
holder with respect to the principal amount thereof may be limited to an amount
equal to the sum of
 
    (1) the initial price of the Exchange Debentures and
 
    (2) that portion of the original issue discount that is not deemed to
       constitute "unmatured interest" for purposes of the U.S. Bankruptcy Code.
       Any original issue discount that was not amortized as of any such
       bankruptcy filing would constitute "unmatured interest."
 
    The Exchange Debenture Indenture requires certain officers of Dobson 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 Dobson and its
Restricted Subsidiaries and Dobson's and its Restricted Subsidiaries'
performance under the Exchange Debenture Indenture and that Dobson 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. Dobson will also be obligated to notify the Trustee of any default or
defaults in the performance of any covenants or agreements under the Exchange
Debenture Indenture.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
    Dobson will not consolidate or merge with, or sell, convey, transfer, lease
or otherwise dispose of all or substantially all of its property and assets in
one transaction or a series of related transactions to any Person or permit any
Person to merge with or into Dobson unless:
 
    (1) Dobson shall be the continuing Person, or the Person (if other than the
       Company) formed by such consolidation or into which Dobson is merged or
       that acquired or leased such property and
 
                                      149
<PAGE>
       assets of Dobson 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 Dobson on all of
       the Exchange Debentures and under the Exchange Debenture Indenture;
 
    (2) immediately after giving effect to such transaction, no Default or Event
       of Default shall have occurred and be continuing;
 
    (3) immediately after giving effect to such transaction on a pro forma
       basis, Dobson or any Person becoming the successor obligor of the
       Exchange Debentures shall have a Consolidated Net Worth equal to or
       greater than the Consolidated Net Worth of Dobson immediately prior to
       such transaction;
 
    (4) immediately after giving effect to such transaction on a pro forma basis
       Dobson, or any Person becoming the successor obligor of the Exchange
       Debentures, as the case may be, could Incur at least $1.00 of
       Indebtedness under the first paragraph of the "Limitation on
       Indebtedness" covenant; on the condition that this clause (4) shall not
       apply to a consolidation or merger with or into a Wholly Owned Restricted
       Subsidiary with a positive net worth. However, in connection with any
       such merger or consolidation, no consideration, other than Common Stock
       in the surviving Person or Dobson, shall be issued or distributed to the
       stockholders of Dobson; and
 
    (5) Dobson delivers to the Trustee an Officers' Certificate (attaching the
       arithmetic computations to demonstrate compliance with clauses (3) and
       (4) above) 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. However
       clauses (3) and (4) above will not apply if, in the good faith
       determination of the Board of Directors of Dobson, whose determination
       shall be evidenced by a Board Resolution, the principal purpose of the
       transaction is to change the state of incorporation of Dobson and the
       transaction shall not have as one of its purposes the evasion of the
       foregoing limitations.
 
DEFEASANCE
 
    DEFEASANCE AND DISCHARGE.  The Exchange Debenture Indenture provides that
Dobson will be deemed to have paid and will be discharged from any and all
obligations in respect of the Exchange Debentures on the 123rd day after the
deposit referred to below, and the provisions of the Exchange Debenture
Indenture will no longer be in effect with respect to the Exchange Debentures
(except for, among other matters, certain obligations to register the transfer
or exchange of the Exchange Debentures, to replace stolen, lost or mutilated
Exchange Debentures, to maintain paying agencies and to hold monies for payment
in trust) if, among other things,
 
    (1) Dobson 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 Exchange Debentures on the Stated Maturity of
       such payments in accordance with the terms of the Exchange Debenture
       Indenture and the Exchange Debentures,
 
    (2) Dobson has delivered to the Trustee
 
       (a) either
 
           - 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
             Dobson'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
 
                                      150
<PAGE>
             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
 
           - a ruling directed to the Trustee received from the Internal Revenue
             Service to the same effect as the aforementioned Opinion of Counsel
             and
 
       (b) 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,
 
(3) 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 Dobson or any of its Subsidiaries is a party or by which
    Dobson or any of its Subsidiaries is bound,
 
(4) Dobson is not prohibited from making payments in respect of the Exchange
    Debentures by the provisions described above under "--Ranking" and
 
(5) if at such time the Exchange Debentures are listed on a national securities
    exchange, the Company has delivered to the Trustee an Opinion of Counsel to
    the effect that the Exchange Debentures will not be delisted as a result of
    such deposit, defeasance and discharge.
 
    DEFEASANCE OF CERTAIN COVENANTS AND CERTAIN EVENTS OF DEFAULT.  The Exchange
Debenture Indenture further provides that the provisions of the Exchange
Debenture Indenture will no longer be in effect with respect to clauses (3) and
(4) under "Consolidation, Merger and Sale of Assets" and all the covenants
described herein under "Covenants," clauses (3) and (4) under "Events of
Default" with respect to such clauses (3) and (4) under "Consolidation, Merger
and Sale of Assets" and such covenants and clauses (5) and (6) 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
Exchange Debentures on the Stated Maturity of such payments in accordance with
the terms of the Exchange Debenture Indenture and the Exchange Debentures, the
satisfaction of the provisions described in clauses (B)(2), (C), (D) and (E) of
the preceding paragraph and the delivery by Dobson 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 Dobson
exercises its option to omit compliance with certain covenants and provisions of
the Exchange Debenture Indenture with respect to the Exchange Debentures as
described in the immediately preceding paragraphs and the Exchange Debentures
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
Exchange Debentures at the time of their Stated Maturity but may not be
sufficient to pay amounts due on the Exchange Debentures at the time of the
acceleration resulting from such Event of Default. However, Dobson will remain
liable for such payments.
 
                                      151
<PAGE>
MODIFICATION AND WAIVER
 
    Modifications and amendments of the Exchange Debenture Indenture may be made
by Dobson and the Trustee with the consent of the holders of not less than a
majority in aggregate principal amount of the outstanding Exchange Debentures.
However, no such modification or amendment may, without the consent of each
holder affected thereby,
 
    (1) change the Stated Maturity of the principal of, or any installment of
       interest on, any Exchange Debenture,
 
    (2) reduce the principal amount of, premium, if any, or interest on, any
       Exchange Debenture,
 
    (3) change the place or currency of payment of principal of premium, if any,
       or interest on, any Exchange Debenture,
 
    (4) 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 Exchange Debenture,
 
    (5) modify the subordination provisions in a manner adverse to the holders
       in any material respect,
 
    (6) reduce the above-stated percentage of outstanding Exchange Debentures
       the consent of whose holders is necessary to modify or amend the Exchange
       Debenture Indenture,
 
    (7) waive a default in the payment of principal of, premium, if any, or
       interest on, the Exchange Debentures,
 
    (8) modify any of the provisions of the Exchange Debenture Indenture
       described under "--Ranking" in a manner adverse to the Holders, or
 
    (9) reduce the percentage of aggregate principal amount of outstanding
       Exchange Debentures the consent of whose holders is necessary for waiver
       of compliance with certain provisions of the Exchange Debenture Indenture
       or for waiver of certain defaults.
 
NO PERSONAL LIABILITY OF INCORPORATORS, SHAREHOLDERS, OFFICERS, DIRECTORS OR
  EMPLOYEES
 
    The Exchange Debenture Indenture will provide that no recourse for the
payment of the principal of, premium, if any, or interest on, any of the
Exchange Debentures, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
Dobson contained in the exchange Indenture or in any of the Exchange Debentures,
or because of the creation of any Indebtedness represented thereby, shall be had
against any incorporator or past, present or future shareholder, officer,
director, employee or controlling person of Dobson. Each holder, by accepting
such Exchange Debenture, waives and releases all such liability.
 
CONCERNING THE TRUSTEE
 
    The Exchange Debenture Indenture provides that, except during the
continuance of an Event of Default, the Trustee will perform only such duties as
are specifically set forth in the Exchange Debenture Indenture. If an Event of
Default has occurred and is continuing, the Trustee will exercise those rights
and powers vested in it under such Exchange Debenture Indenture and use the same
degree of care and skill in its exercise of such rights and powers as a prudent
person would exercise under the circumstances in the conduct of such person's
own affairs.
 
    The Exchange Debenture Indenture and provisions of the Trust Indenture Act
of 1939, as amended, incorporated by reference in the Exchange Debenture
Indenture, contain limitations on the rights of the Trustee thereunder, should
it become a creditor of Dobson, 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 engaged in other
transactions. However, if the Trustee acquires any conflicting interest, it must
eliminate such conflict or resign.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
   
DOBSON/SYGNET CREDIT FACILITIES
    
 
   
    The Dobson/Sygnet Credit 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 by Dobson/Sygnet 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 Dobson/Sygnet Credit
Facilities does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, the definitive loan documentation. Capitalized
terms that are used but not defined in this section have the meanings that are
given such terms in the Commitment Letter.
    
 
   
    The Dobson/Sygnet Credit Facilities aggregate $430.0 million and include
    
 
    - a $50.0 million, 7 3/4 year reducing revolving credit facility,
 
    - a $125.0 million, 7 3/4 year term loan ("Term Loan A"),
 
    - a $155.0 million, 8 1/4 year term loan ("Term Loan B"), and
 
    - a $100.0 million, 9 year term loan ("Term Loan C").
 
    Borrowings under the Revolving Credit Facility and Term Loans A and B bear
interest payable at least quarterly, at Sygnet's option, at
 
    (1) the "Applicable Margin" plus the greater of
 
       - the Federal Funds Effective Rate plus 0.5%, and
 
       - the prime rate (the "Base Rate"), or
 
    (2) 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 bears 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:

    The commitments under the Dobson/Sygnet Credit Facilities will be
permanently reduced by:
    
 
    - 100% of the net cash proceeds from sales of assets in excess of $5.0
      million to the extent not reinvested within 12 months,
 
    - an amount equal to 100% of the net cash proceeds received from certain
      equity or debt issuances, and
 
    - 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.
 
    We 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 Dobson/Sygnet Credit 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 Dobson/Sygnet Credit
Facilities contain other usual and customary negative and affirmative covenants,
including Year 2000 compliance.
    
 
   
    The Dobson/Sygnet Credit Facilities restrict Sygnet from declaring and
paying distributions or making restrictive payments. However, Sygnet will be
permitted to pay dividends to pay
    
 
    - scheduled interest on the Dobson/Sygnet Notes commencing after the first
      six interest payments on the Dobson/Sygnet Notes, and
 
    - regularly scheduled payments on up to $120,000,000 in liquidation
      preference value of our 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
 
                                      154
<PAGE>
dividend or distribution. However, with respect to any event of default other
than a payment default, a bankruptcy event with respect to Sygnet or us or any
of our respective restricted subsidiaries or the loss of a material license or
cellular system, Sygnet's subsidiary will not be prohibited from paying
dividends to Dobson/Sygnet to pay scheduled interest on the Dobson/Sygnet Notes
for more than 180 days.

       - 1.50 to 1 from January 1, 2000 to December 31, 2000

    must be greater than 1.00 to 1
 
   
    In addition, the Dobson/Sygnet Credit Facilities require both Sygnet and us
to maintain a ratio of debt to operating cash flow. We and Sygnet believe that
we have maintained all of the above required ratios.
    
 
   
    Failure to satisfy any of the financial covenants will constitute an Event
of Default under the Dobson/ Sygnet Credit 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 Dobson/Sygnet Credit 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 us or
      any of our subsidiaries;
 
    - cross default to other material indebtedness, leases, contracts of Sygnet,
      its subsidiaries, or of us and our subsidiaries (excluding Logix);
 
    - any material adverse change; dissolution or termination of Sygnet or any
      of its subsidiaries or of us;
 
    - if we fail to maintain direct voting and economic control of Sygnet and
      its subsidiaries; and
 
    - if less than two-thirds of our existing executive management team
      continues to hold executive positions with us.

    Sygnet's obligations under the Dobson/Sygnet Credit Facilities are
guaranteed by its subsidiary. Borrowings under the Dobson/Sygnet Credit
Facilities are 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.
    
 
TOWER CREDIT FACILITY
 
    Dobson Tower obtained a $17.5 million term loan (the "Tower Credit
Facility"), which is secured by all assets of Dobson Tower. The Tower Credit
Facility matures on December 22, 1999 and bears interest at a fixed rate of 8.0%
per annum. The terms of the Tower Credit Facility require, among other things,
that Dobson Tower provide to the lender an executed contract with a third party
acceptable to the lenders providing for the sale of the towers by June 23, 1999.
 
   
THE DOC CREDIT FACILITY
    
 
   
    Our DOC Credit Facility is a $250.0 million senior secured revolving credit
facility with NationsBank and certain other lenders. The following summary of
the material provisions of the DOC Credit Facility does not purport to be
complete and is subject to, and is qualified in its entirety by reference to,
the DOC Credit Facility. Capitalized terms that are used but not defined in this
section have the meanings that are given such terms in the DOC loan agreement.
    
 
   
    The DOC Credit Facility matures on June 30, 2006. Borrowings under the DOC
Credit Facility bear interest, payable at least quarterly, at DOC's option, at
an annual rate equal to either
    
 
    (1) the greater of
 
       - the federal funds rate plus 1/2% and
 
       - the prime rate of NationsBank, plus in each case a percentage per annum
         ranging from 0% to 1(1)%, or
 
    (2) a LIBOR-based rate plus a percentage per annum ranging from 1% to
2 1/4%. The amount of additional interest applicable to either option is based
on Dobson's quarterly Total Leverage Ratio.
 
    In the event DOC's Senior Leverage Ratio is greater than 5.0 to 1, the
additional interest applicable to either option will be increased by .125%. We
believe we have maintained the required Senior Leverage Ratio.
 
   
    Commencing with the quarter ending June 30, 2000, the borrowing commitment
under the DOC Credit Facility will reduce quarterly in percentage increments of
3.33% for the three quarters ending December 31, 2000,
    
 
    - 3.75% for the eight quarters ending December 31, 2002,
 
    - 4.375% for the eight quarters ending December 31, 2004,
 
    - 3.75% for the four quarters ending December 31, 2005, and
 
    - 5% for the two quarters ending June 30, 2006.
 
   
    A mandatory prepayment and reduction of the borrowing commitment will be
required at the time of, and in an amount equal to 100% of the net proceeds
from, certain sales of material assets of DOC and its Restricted Subsidiaries
and in connection with the incurrence of certain indebtedness by DOC. In
addition, if DOC's Senior Leverage Ratio is greater than 5.5 to 1, the proceeds
from any issuance of unsecured indebtedness by us must be used to repay
borrowings under the DOC Credit Facility and reduce the borrowing commitment
thereunder.
    
 
   
    The DOC Credit Facility contains a number of covenants including, among
others, covenants limiting the ability of DOC and DOC's Restricted Subsidiaries
and us to incur debt, make loans or guarantees,
    
 
                                      156
<PAGE>
   
create liens, pay dividends, make distributions or stock repurchases, make
investments, enter into sale and lease-back transactions, change their business,
sell assets, engage in mergers and acquisitions and enter into transactions with
affiliates. Acquisitions must be limited to the domestic cellular industry and
approval of the lenders is required for any acquisition in excess of $75.0
million, if our Total Leverage Ratio (including all of our Subsidiaries) is
greater than 8.5 to 1 (giving pro forma effect to the acquisition). The DOC
Credit Facility contains other customary affirmative covenants.
    
 
   
    The DOC Credit Facility restricts DOC from declaring and paying dividends or
distributions, including dividends to pay cash dividends on the Senior Preferred
Stock and the Preferred Stock and to pay scheduled interest on the Senior Notes
and, if issued, the Exchange Debentures and the Senior Exchange Debentures.
However, DOC is permitted to pay dividends or distributions to us to pay cash
dividends on the Senior Preferred Stock (or interest on the Senior Exchange
Debentures and the Exchange Debentures, if issued) after January 15, 2003, and
scheduled interest on the Senior Notes commencing after the first four interest
payments on the Senior Notes, unless 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. However, with respect to any event of
default (other than a payment default (including by way of acceleration), a
bankruptcy event with respect to DOC or us, or the loss of a material license or
cellular system), DOC will not be prohibited from paying dividends to us to pay
scheduled interest on the Senior Notes or Senior Exchange Debentures if issued,
or dividends on the Senior Preferred Stock for more than 180 days. In addition,
DOC may pay dividends to us up to $7.5 million per year, not to exceed $25.0
million in the aggregate when DOC's Senior Leverage Ratio is less than 6.5 to 1
(giving pro forma effect to the payment). However, to the extent funds are
contributed to DOC in the form of equity or unsecured subordinated loans, the
amount of dividends DOC may pay to us may be increased by the amount so
contributed, but in no event not to exceed $25 million per year and $50 million
in the aggregate, without regard to DOC's Senior Leverage Ratio.
    
 
    We are required to comply with certain financial tests and maintain certain
financial ratios, including, among others, a requirement that
 
    (1) DOC's Senior Leverage Ratio not exceed
 
       - 6.5 to 1 from July 1 to December 31, 1998,
 
       - 6.25 to 1 from January 1 to June 30, 1999,
 
       - 6.0 to 1 from July 1 to December 31, 1999,
 
       - 5.5 to 1 from January 1 to June 30, 2000,
 
       - 5.0 to 1 from July 1 to December 31, 2000, and
 
       - 4.5 to 1 from January 1, 2001 and thereafter,
 
    (2) the ratio of DOC's Operating Cash Flow to its Pro Forma Debt Service
       exceed 1.15 to 1;
 
    (3) the ratio of DOC's Operating Cash Flow to its Cash Interest Expense
       (with an add-back for escrowed interest payments on the Senior Notes) for
       the most recently ended four quarters exceed 2.0 to 1;
 
    (4) DOC's Fixed Charge Coverage Ratio be greater than 1.0 to 1;
 
    (5) the Company's Total Leverage Ratio not exceed
 
       - 9.5 to 1 through June 30, 1998,
 
       - 9.0 to 1 from July 1 to December 31, 1998,
 
       - 8.5 to 1 from January 1 to June 30, 1999,
 
                                      157
<PAGE>
       - 8.0 to 1 from July 1 to December 31, 1999,
 
       - 7.0 to 1 from January 1 to June 30, 2000,
 
       - 6.0 to 1 from July 1 to December 31, 2000, and
 
       - 5.0 to 1 from January 1, 2001 and thereafter; and
 
    (6) Dobson's Consolidated Operating Cash Flow to its Consolidated Interest
       Expense for the most recently ended four quarters exceed 1.25 to 1.
 
    We believe we have complied with all required financial tests and we believe
that we have maintained all required financial ratios.
 
    For purposes of the financial covenants, "Operating Cash Flow" for DOC is
 
    - Operating Cash Flow of DOC and its Restricted Subsidiaries, including
      certain cash flows of the "Cellular Operating Partnerships" which are
      Oklahoma RSA 5 Limited Partnership, Oklahoma RSA 7 Limited Partnership,
      Texas RSA No. 2 Limited Partnership, Gila River Cellular General
      Partnership and any other entity in which DOC or one of its Restricted
      Subsidiaries owns a partnership interest and serves as the managing
      general partner, multiplied by
 
    - DOC's ownership interest in the partnerships,
 
except if DOC provides financing to any of the Cellular Operating Partnerships
that are not 100% owned by DOC, 100% of the Operating Cash Flow of the
partnership will be included in the definition of DOC's Operating Cash Flow, and
for us is defined as our Operating Cash Flow together with that of our
Restricted Subsidiaries, in each case for the four most recently completed
quarters. "Operating Cash Flow" for any period is
 
    - the sum of pre-tax income, without giving effect to extraordinary losses
      or gains, interest, depreciation and amortization expenses and non-cash
      charges, minus
 
    - interest and dividend income, reductions in deferred taxes and other
      non-cash components of income.
 
    "Total Debt" of DOC and its Restricted Subsidiaries is the sum of all
obligations for borrowed money, all payments required under non-compete
agreements, capital lease obligations, amounts required under installment sale
purchases, all financial obligations of others guaranteed by DOC, and any
amounts for which DOC is contingently liable to provide as equity or debt
advances to other parties, but does not include intercompany subordinated debt
owed by DOC to us or to any of our subsidiaries not owned by DOC. "Total Debt"
of our Restricted Subsidiaries and us is the sum of
 
    - all obligations for borrowed money (less the amount escrowed for interest
      payments on the Senior Notes),
 
    - all payments required under noncompete agreements,
 
    - capital lease obligations,
 
    - amounts required under installment sale purchases,
 
    - all financial obligations of others guaranteed, and
 
    - any amounts for which we and any of our Restricted Subsidiaries are
      contingently liable to provide as equity or debt advances to other
      parties.
 
At such time as the Senior Preferred Stock is exchanged for Senior Exchange
Debentures, the obligations under the Senior Exchange Debentures will be
included in the calculation of Total Debt.
 
                                      158
<PAGE>
    "Pro Forma Debt Service" is the sum of Pro Forma Interest Expense and
payments scheduled to be made on Total Debt for the succeeding twelve months.
 
    "Pro Forma Interest Expense" is the result obtained by multiplying the
average debt outstanding during the period by the interest rate in effect at the
time of calculation.
 
    "Fixed Charge Coverage Ratio" is defined as the ratio of
 
    - the Operating Cash Flow of DOC for the most recently ended four quarters
      to
 
    - the sum of all payments of DOC's Total Debt required to be paid, cash
      interest expense and capital expenditures of DOC, cash taxes, and
      distributions and dividends paid by DOC, in each case for the most
      recently ended four quarters.
 
    DOC's "Senior Leverage Ratio" is defined as the ratio of Total Debt of DOC
and its Restricted Subsidiaries to Operating Cash Flow of DOC and its Restricted
Subsidiaries.
 
    Our "Total Leverage Ratio" is the ratio of our Total Debt to our Operating
Cash Flow.
 
    "Restricted Subsidiaries" include Dobson Cellular of Arizona, Inc., Dobson
Cellular of Enid, Inc., Dobson Cellular of Kansas/Missouri, Inc., Dobson
Cellular of Maryland, Inc., Dobson Cellular of Woodward, Inc. and Dobson
Cellular Systems, Inc. and its subsidiaries.
 
   
    Failure to satisfy any of the financial covenants will constitute an Event
of Default under the DOC Credit Facility, permitting the lenders, after notice,
to terminate this commitment and/or accelerate payment of outstanding
indebtedness notwithstanding our ability to meet our debt service obligations.
The DOC Credit Facility also includes other customary events of default,
including, without limitation, a cross-default to other indebtedness, loss of
any material license, material adverse change, bankruptcy and change of control.
In addition, the definition of events of default includes the loss of Everett R.
Dobson as part of the senior management team.
    
 
   
    We have guaranteed DOC's obligations under the DOC Credit Facility as have
DOC's Restricted Subsidiaries. Borrowings under the DOC Facility are secured by
all assets of DOC and its present and future subsidiaries, and by a pledge of
the stock of DOC and the stock of and partnership interests in its Restricted
Subsidiaries.
    
 
   
THE DCOC CREDIT FACILITY
    
 
   
    The DCOC Credit Facility is a $200.0 million senior secured revolving credit
facility with NationsBank and certain other lenders, under which such lenders
provided funds to DCOC to finance the Texas 16 and California 4 Acquisitions and
have agreed to provide additional funds to finance other acquisitions, capital
expenditures, permitted investments and restricted payments and for general
corporate purposes of DCOC and its subsidiaries. The following summary of the
material provisions of the DCOC Credit Facility does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, the DCOC
Credit Facility loan agreement. Capitalized terms that are used but not defined
in this section have the meanings that are given such terms in the DCOC Credit
Facility loan agreement.
    
 
   
    The DCOC Credit Facility includes
    
 
    - a $120 million, eight and one-half year reducing revolving credit
      facility, and
 
    - an $80 million 364-day revolving credit facility which, at DCOC's option,
      may be converted into a term loan maturing no later than eight and
      one-half years from the closing date of the New Credit Facilities or, with
      the consent of the lenders, may be renewed for an additional 364-day
      period.
 
   
    In addition, the DCOC Credit Facility loan agreement contemplates an
additional $75 million revolving credit facility may be established in the
future, although the lenders will have no obligation to
    
 
                                      159
<PAGE>
provide such additional financing. The uncommitted acquisition revolver facility
may not be established unless two-thirds of the commitment amount under the
committed facilities is outstanding.
 
   
    The facilities comprising the DCOC Credit Facility will mature on June 30,
2006. Borrowings under the DCOC Credit Facility bear interest, payable at least
quarterly, at DCOC's option, at an annual rate equal to either
    
 
    (1) the greater of
 
       - the federal funds rate plus 1/2%, and
 
       - the prime rate of NationsBank,
 
plus in each case a percentage per annum ranging from 1/8% to 1 3/8%, or
 
    (2) a LIBOR-based rate plus a percentage per annum ranging from 1 1/8% to
2 3/8%.
 
The amount of additional interest applicable to either option is based on DCOC's
Leverage Ratio.
 
   
    Commencing with the quarter ending June 30, 2000, we must reduce the
borrowing commitment under the DCOC Credit Facility in percentage increments of
    
 
    - 3.33% for the three quarters ending December 31, 2000,
 
    - 3.75% for the eight quarters ending December 31, 2002,
 
    - 4.375% for the eight quarters ending December 31, 2004,
 
    - 3.75% for the four quarters ending December 31, 2005 and
 
    - 5% for the two quarters ending June 30, 2006.
 
    A mandatory prepayment and reduction of the borrowing commitment will be
required at the time, and in an amount equal to 100% of the net proceeds from
certain sales of material assets of DCOC and its subsidiaries and the issuance
of certain indebtedness by DCOC.
 
   
    The DCOC Credit Facility contains a number of covenants including, among
others, covenants limiting the ability of DCOC and its subsidiaries to incur
debt, make loans or guarantees, create liens, pay dividends, make distributions
or stock repurchases, make investments, enter into sale and lease-back
transactions, change their business, sell, exchange, lease or otherwise dispose
of assets, engage in mergers, make acquisitions and enter into transactions with
affiliates. Approval of the lenders is required for any acquisition in excess of
$75 million when our Total Leverage Ratio (including Restricted and Unrestricted
Subsidiaries) is greater than 8.5 to 1 (giving pro forma effect to the
acquisition). For 1998, DCOC's capital expenditures will be limited to 110% of
its capital expenditures budget for such period. The DCOC Credit Facility
contains other covenants customary for similar credit facilities.
    
 
   
    The DCOC Credit Facility prohibits distributions or restricted payments,
except that, after giving pro forma effect to any such distribution or payment,
when DCOC's Leverage Ratio is less than 5.0 to 1, payments may be made with up
to 100% of Free Cash Flow and when DCOC's Leverage Ratio is greater than or
equal to 5.0 to 1, payments may be made with up to 50% of Free Cash Flow. In
addition, the DCOC Facility restricts DCOC from declaring and paying dividends
or distributions, including dividends to pay cash dividends on the Senior
Preferred Stock and the Preferred Stock and to pay scheduled interest on the
Senior Notes and, if issued, the Senior Exchange Debentures and the Exchange
Debentures. However, after January 15, 2003 DCOC will be permitted to pay
dividends or distributions to us to pay cash dividends on the Senior Preferred
Stock and the Preferred Stock and scheduled interest on the Senior Exchange
Debentures and the Exchange Debentures, if issued, unless 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. However, with respect to any
event of default, other than a payment default, a bankruptcy event with respect
to the
    
 
                                      160
<PAGE>
Company or DCOC or the loss of a material license or cellular system, DCOC will
not be prohibited from paying dividends to us to pay dividends on the Senior
Preferred Stock and the Preferred Stock or scheduled interest on the Senior
Exchange Debentures and the Exchange Debentures, if issued, for more than 180
days.
 
    DCOC is required to comply with certain financial tests and maintain certain
financial ratios, including, among others, a requirement that
 
    (1) DCOC's Leverage Ratio not exceed
 
       - 7.5 to 1 through September 30, 1998,
 
       - 7.0 to 1 from October 1, 1998 to June 30, 1999,
 
       - 6.5 to 1 from July 1 to December 31, 1999,
 
       - 5.5 to 1 from January 1 to December 31, 2000, and
 
       - 4.5 to 1 from January 1, 2001 and thereafter.
 
When Operating Cash Flow for the most recently ended four quarters exceeds $20.0
million, the applicable ratios range from 8.0 to 1 for the first period to 5.0
to 1 for the last period and when Operating Cash Flow for the most recently
ended four quarters exceeds $25 million, the applicable ratios range from 8.5 to
1 for the first period to 5.5 to 1 for the last period;
 
    (2) the ratio of DCOC's Operating Cash Flow to its Pro Forma Debt Service
shall exceed 1.25 to 1;
 
    (3) the ratio of DCOC's Operating Cash Flow to its Cash Interest Expense for
the most recently ended four quarters exceed 1.75 to 1 until December 31, 1998
and 2.0 to 1 thereafter; and
 
    (4) the Fixed Charge Coverage Ratio be greater than 1.0 to 1.
 
    We believe that DCOC has complied with all financial tests and has
maintained all required financial ratios.
 
    For purposes of the financial covenants, "Operating Cash Flow" for DCOC
includes the Operating Cash Flow of any "Cellular Operating Partnership" which
includes any entity in which DCOC or one of its subsidiaries owns a partnership
interest or serves as the managing general partner multiplied by DCOC's
ownership interest in the partnership. If DCOC provides financing to any of the
Cellular Operating Partnerships that are not 100% owned by DCOC, 100% of the
Operating Cash Flow of the partnership will be included in DCOC's Operating Cash
Flow.
 
    Our "Operating Cash Flow" includes the Operating Cash Flow of our Restricted
Subsidiaries and us.
 
    "Operating Cash Flow" for any period is defined as
 
    (1) the sum of pre-tax income, without giving effect to any extraordinary
       losses or gains, interest, depreciation and amortization expenses and
       non-cash charges, minus
 
    (2) interest and dividend income, reductions in deferred taxes and other
       non-cash components of income.
 
    "Total Debt" of DCOC is the sum of
 
    - all obligations of DCOC and its subsidiaries for borrowed money,
 
    - all payments required under non-compete agreements, capital lease
      obligations,
 
    - amounts required under installment sale purchases,
 
    - all financial obligations of others guaranteed by DCOC, and
 
                                      161
<PAGE>
    - any amounts for which DCOC is contingently liable to provide as equity or
      debt advances to other parties.
 
    "Total Debt" does not include intercompany subordinated debt owed by DCOC to
us.
 
    "Total Debt" of our Restricted Subsidiaries and us is the sum of
 
    - all obligations for borrowed money (less the amount escrowed for interest
      payments on the Senior Notes),
 
    - all payments required under noncompete agreements,
 
    - capital lease obligations,
 
    - amounts required under installment sale purchases,
 
    - all financial obligations of others guaranteed, and,
 
    - any amounts for which we and any of our Restricted Subsidiaries are
      contingently liable to provide as equity or debt advances to other
      parties.
 
At such time as the Senior Preferred Stock and the Preferred Stock are exchanged
for the Senior Exchange Debentures and the Exchange Debentures, the obligations
under the Exchange Debentures will be included in the calculation of Total Debt.
 
    "Pro Forma Debt Service" is the sum of Pro Forma Interest Expense and
payments scheduled to be made on DCOC's Total Debt for the succeeding twelve
months.
 
    "Pro Forma Interest Expense" is the result obtained by multiplying
 
    - the sum of (a) DCOC's Total Debt at the beginning of the period plus (b)
      such Total Debt minus payments scheduled to be made thereon during the
      period, divided by two by
 
    - the interest rate in effect at the time of calculation.
 
    "Fixed Charge Coverage Ratio" is the ratio of
 
    - DCOC's Operating Cash Flow for the most recently ended four quarters to
 
    - the sum of all payments on DCOC's Total Debt required to be paid, its cash
      interest expense, capital expenditures, and cash taxes, and distributions
      and dividends paid by DCOC, in each case for the most recently ended four
      quarters.
 
    "Free Cash Flow" is the Operating Cash Flow for any fiscal year less
 
    - cash taxes,
 
    - required principal and interest payments on all debt for such fiscal year,
 
    - capital expenditures, and
 
    - $2.5 million.
 
    DCOC's "Leverage Ratio" is the ratio of its Total Debt to its Operating Cash
Flow. Dobson's "Total Leverage Ratio" is defined as the ratio of its Total Debt
to its Operating Cash Flow.
 
   
    Failure to satisfy any of the financial covenants will constitute an Event
of Default under the DCOC Credit Facility, permitting the lenders, after notice,
to terminate the commitment and/or accelerate payment of outstanding
indebtedness notwithstanding our ability to meet our debt service obligations.
The DCOC Credit Facility includes other customary events of default, including,
without limitation, a cross-default to other material indebtedness, loss of any
material license, material adverse change, bankruptcy,
    
 
                                      162
<PAGE>
change of control and a change of management resulting in less than two-thirds
of existing management being in control of DCOC.
 
   
    DCOC's obligations under the DCOC Credit Facility will be guaranteed by all
of DCOC's subsidiaries. Borrowings under the New Credit Facilities are secured
by all assets of DCOC and its present and future subsidiaries, and by a pledge
of the stock of and partnership interests in DCOC's subsidiaries.
    
 
THE SENIOR NOTES
 
    GENERAL.  We have outstanding $160.0 million in aggregate principal amount
of Senior Notes which mature in April 2007. The Senior Notes were issued under
the Senior Note Indenture with United States Trust Company of New York, as
Trustee. The Senior Notes bear interest at an annual rate of 11 3/4%, payable
semi-annually on each April 15 and October 15. Capitalized terms hereafter used
in this summary have the meanings set forth in the Senior Note Indenture.
 
    RANKING.  The Senior Notes are our unsubordinated indebtedness, ranking
equal in right of payment with all other unsubordinated indebtedness and senior
in right of payment to all of our existing and future subordinated indebtedness.
 
   
    OPTIONAL REDEMPTION.  We may, at our option, redeem all or any portion of
the Senior Notes at the redemption prices, expressed as percentages of the
principal amount of the Senior Notes set forth below, plus, in each case,
accrued interest thereon to the applicable redemption date, if redeemed during
the 12-month period beginning April 15 of the years indicated:

is a summary and is qualified in its entirety by the provisions of our
Certificate of Incorporation ("Certificate of Incorporation") and Bylaws.

have cumulative voting rights or preemptive or other rights to acquire or
subscribe for additional, unissued or treasury shares.

Stock, equally with the Class A Preferred Stock and, except with respect to
liquidation, the Class G and Class H Preferred Stock, and senior to the Class G
and Class H Preferred Stock as to liquidation. The Class G and Class H Preferred
Stock rank junior to the Class A Preferred Stock and Class F Preferred Stock

as to liquidation.
 
    CLASS A PREFERRED STOCK

    CONVERSION.  The Class A Preferred Stock is not convertible.

<PAGE>
    CLASS B AND CLASS C PREFERRED STOCK
 
   
    As part of the Sygnet acquisition, all of the outstanding shares of Class B
Preferred Stock were converted to Class A Common Stock and we purchased all of
the outstanding shares of Class C Preferred Stock. We have since retired our
Class B Preferred Stock and our Class C Preferred Stock.
    
 
    CLASS D PREFERRED STOCK AND CLASS E PREFERRED STOCK
 
    On December 23, 1998, Childs and the Dobson Partnership purchased 75,094
shares of Class D Preferred Stock from us for $85.0 million pursuant to an
investment and transaction agreement (the "Class D Purchase Agreement") and
entered into a stockholder and investor rights agreement (the "Investors
Agreement") with certain other of our shareholders, excluding the holders of the
Class F Preferred Stock (collectively, the "Shareholders"), DOC and us. The
Dobson Partnership purchased $4.0 million of Class D Preferred Stock and Childs
purchased substantially all of the remaining $81.0 million of Class D Preferred
Stock. Each share of Class D Preferred Stock is convertible into one share of
Class A Common Stock and one share of Class E Preferred Stock. The following
summary of the Class D Preferred Stock, the Class E Preferred Stock, the Class D
Purchase Agreement and the Investors Agreement does not purport to be complete
and is qualified in its entirety by reference to the applicable certificates of
designation and such agreements.
 
    CLASS D PURCHASE AGREEMENT.  The Class D Purchase Agreement contains various
covenants which, among other things, give the holders of Class D Preferred Stock
certain preemptive rights with respect to our issuance of equity securities
(including rights, options or warrants with respect to such securities and other
securities convertible into equity securities), restrict our ability and that of
our subsidiaries to pay dividends, purchase their outstanding equity securities,
make investments, acquire or dispose of material amounts of assets, engage in
sale and leaseback transactions, or merge, consolidate or dispose of all or
substantially all of their assets. In addition, holders of Class D Preferred
Stock will be entitled to participate in the spin-off of Logix.
 
    CLASS D PREFERRED STOCK CERTIFICATE OF DESIGNATION.  The certificate of
designation for the Class D Preferred Stock (the "Class D Preferred Stock
Certificate of Designation") provides for the following rights, including voting
rights, preferences and powers:
 
    VOTING RIGHTS.  Except as otherwise provided by law, the shares of Class A
Common Stock and Class D Preferred Stock vote together on all matters submitted
to a vote of the shareholders. Each share of Class D Preferred Stock, which is
initially convertible into one share of Class A Common Stock and one share of
Class E Preferred Stock, is entitled to the number of votes that the shares of
Class A Common Stock issuable upon conversion of the Class D Preferred Stock
would have on the record date fixed for any meeting, or the effective date of
action taken by written consent, of shareholders.
 
    Approval of the holders of a majority of the outstanding Class D Preferred
Stock is necessary to
 
    - authorize or increase the authorized number of shares of, or issue, any
      class or a series of capital stock ranking prior to, or on a parity with,
      the Class D Preferred Stock other than preferred stock issued to finance
      acquisitions and capital projects,
 
    - make any change in the Certificate of Incorporation which would adversely
      affect the powers, preferences or rights, including voting rights, of the
      Class D Preferred Stock,
 
    - authorize or effect the sale of all or substantially all of our assets,
      our merger or consolidation resulting in a change of control, or our
      liquidation, dissolution or winding up,
 
    - amend our Certificate of Incorporation or Bylaws to change the authorized
      number of directors or
 
                                      167
<PAGE>
    - authorize redemption, repurchase or payment of dividends on any junior or
      parity stock, except for scheduled or mandatory redemptions thereof and
      repurchases of management stock pursuant to contractual rights.
 
    DIVIDENDS.  Cumulative dividends on each share of Class D Preferred Stock
accrue daily at the annual rate of 15% on the sum of the $1,131.92 per share
liquidation value. In addition, a holder of Class D Preferred Stock is entitled
to receive additional dividends thereon in the same amounts as such holder would
have received if such shares of Class D Preferred Stock had been fully converted
into Class A Common Stock. All accumulated and unpaid dividends on the Class D
Preferred Stock ("Class D Accrued Dividends") from the date of issuance,
compounded annually, are payable in cash on the liquidation, dissolution or
winding up of the Company, or any redemption of Class D Preferred Stock or the
exercise of any put or call rights in respect thereof. Upon conversion of Class
D Preferred Stock into shares of Class A Common Stock and Class E Preferred
Stock, holders of Class D Preferred Stock will receive Class D Accrued Dividends
in additional shares of Class E Preferred Stock.
 
    The Financing Agreements limit and, if exchange debentures are issued for
the Senior Preferred Stock or the Preferred Stock, each exchange debenture
indenture will limit, and for the foreseeable future effectively prohibit, the
payment of cash dividends on the Class D Preferred Stock.
 
    The Class D Preferred Stock Certificate of Designation prohibits the
declaration or payment of dividends on or redemption or purchase of any junior
securities by us, our subsidiaries and our affiliates.
 
   
    On April 13, 1999, Childs agreed to sell 15,474 shares of Class D Preferred
Stock and certain shares of our common stock to AT&T Wireless. The transaction
is subject to compliance with the Hart-Scott-Rodino Act and other customary
closing conditions.
    
 
    CONVERSION.  At any time and from time to time, any holder of Class D
Preferred Stock may convert each share of Class D Preferred Stock held into one
share of Class A Common Stock, subject to adjustment to prevent dilution, and
one share of Class E Preferred Stock.
 
    REDEMPTION.  All of the Class D Preferred Stock must be redeemed for its
liquidation preference plus Class D Accrued Dividends, subject to the legal
availability of funds therefor, following the vote of the holders of a majority
of the outstanding shares of Class D Preferred Stock and Class E Preferred
Stock, voting together as a single class, at any time after December 23, 2010.
Our obligation to redeem the Class D Preferred Stock is subject to the terms of
the Financing Agreements.
 
    CLASS E PREFERRED STOCK CERTIFICATE OF DESIGNATION.  The certificate of
designation for the Class E Preferred Stock provides for the following rights,
preferences and powers:
 
    VOTING RIGHTS.  Except as otherwise required by law and as authorized to
vote with the holders of Class D Preferred Stock for redemption, the holders of
shares of Class E Preferred Stock have no voting rights.
 
    DIVIDENDS.  Cumulative dividends on each share of Class E Preferred Stock
accrue daily at the annual rate of 15% on the sum of the $1,131.92 per share
liquidation value. All accumulated and unpaid dividends on the Class E Preferred
Stock ("Class E Accrued Dividends") from the date of issuance, compounded
annually, are payable in cash only upon our liquidation, dissolution or winding
up or on redemption of or exercise of the put and call rights with respect to
the Class E Preferred Stock. The Financing Agreements limit, and, if exchange
debentures are issued for either the Senior Preferred Stock or the Preferred
Stock, each exchange debenture indenture will limit, and for the foreseeable
future effectively prohibit, the payment of cash dividends on the Class E
Preferred Stock.
 
    CONVERSION.  The Class E Preferred Stock is not convertible.
 
                                      168
<PAGE>
    REDEMPTION.  We are obligated to redeem all of the Class D and Class E
Preferred Stock for its liquidation preference plus Class E Accrued Dividends,
subject to legal availability of funds therefor, following the vote of the
holders of a majority of the outstanding shares of Class D Preferred Stock and
the Class E Preferred Stock, voting together as a single class, at any time
after December 23, 2010, or, with respect to Class E Preferred Stock only, upon
completion of an initial public offering of our common stock resulting in gross
proceeds of at least $50.0 million. Our obligation to redeem our Class D and
Class E Preferred Stock is subject to the terms of the Financing Agreements.
 
    PUT AND CALL OPTIONS.  Upon the earliest to occur of December 23, 2005, a
"Change of Control," as defined below, or the consummation of an initial public
offering of our common stock, and if the holders of a majority of Class E
Preferred Stock vote to require the purchase of their stock, each holder will
have the right to require us to purchase the Class E Preferred Stock for its per
share liquidation preference plus Class E Accrued Dividends, subject to the
terms of the Financing Agreements. A "Change of Control" means any transaction
that results in the voting power of our voting stock controlled by Everett R.
Dobson and his affiliates being less than 50.1% and the sale of all or
substantially all our capital stock, business or assets, but does not include
the sale or redemption by the Dobson Partnership of up to $25.0 million of our
capital stock or our initial public offering of our common stock. To the extent
of cash available, we must pay cash to purchase the Class E Preferred Stock. To
the extent we do not have available cash, we are obligated to issue one or more
junior subordinated promissory notes ranking senior to all preferred stock
existing on the Closing Date other than Class F Preferred Stock and bearing
interest at an initial annual rate of 17%, payable quarterly, subject to the
terms of the Financing Agreements. If any quarterly interest payment is not
made, the annual rate increases by 0.5%, up to a maximum annual rate of 20%.
Quarterly payments of interest and principal on the notes are required to the
extent the Company has available cash and subject to the additional condition
that we have a ratio of cash flow to interest expense of at least 1 to 1 for
such quarter, after giving effect to the payment of interest and principal. To
the extent unpaid, obligations under these notes will mature upon the last to
occur of
 
    - termination of the Credit Facilities,
 
    - termination of the Senior Note Indenture,
 
    - the repurchase, payment or defeasance of the Senior Notes and
 
    - the redemption of all outstanding Senior Preferred Stock and Preferred
      Stock or the elimination of the financial covenants contained in the
      certificates of designation for the Senior Preferred Stock and the
      Preferred Stock.
 
    In connection with our initial public offering of our common stock, we will
have the option to purchase all or any outstanding shares of Class E Preferred
Stock for the liquidation preference thereof, plus Class E Dividends, payable in
cash. Notwithstanding the foregoing, we may not pay the holders subordinated
notes in lieu of cash in the case of a Change of Control in which
 
    - prior to an initial public offering, Everett R. Dobson and his affiliates
      cease to control at least 50.1% of the Company's voting stock, or
 
    - following an initial public offering, Everett R. Dobson and his affiliates
      cease to control at least 35% of the Company's voting stock.
 
   
    INVESTORS AGREEMENT.  Under the Investors Agreement, Childs and the Dobson
Partnership shall have certain demand rights for their shares of Class A Common
Stock issuable upon conversion of the Class D Preferred Stock or otherwise held
and all Shareholders shall have "piggy-back" registration rights for their Class
A Common Stock. The Investors Agreement provides that seven directors will
constitute our Board, one designated by Childs, four designated by the Dobson
Partnership, and two selected jointly by Childs and the Dobson Partnership. So
long as Childs beneficially owns at least 35% of our securities held by it on
December 23, 1998, in addition to the director it may designate, Childs may also
designate an observer to
    
 
                                      169
<PAGE>
   
attend each meeting of the Board and each meeting of any committee of the Board.
Notwithstanding the foregoing, an additional two directors may be designated by
the holders of Senior Preferred Stock, an additional two directors may be
designated by the holders of the Preferred Stock and one additional director by
the holders of the Class F Preferred Stock in the event of the non-payment of
dividends for certain periods (a voting rights triggering event). AT&T Wireless
has executed an agreement to acquire $20 million of Class D Preferred Stock and
Class A Common Stock from Childs. Concurrent with the closing of AT&T Wireless'
stock acquisition, the Investors Agreement will be amended to include AT&T
Wireless as a party. AT&T Wireless will have substantially the same rights under
the Investors Agreement as Childs, including the ability to designate one
director and to jointly designate an additional director with Childs and the
Dobson Partnership. Childs will only have the right to jointly elect one
director with the Dobson Partnership.
    
 
    The Shareholders will have preemptive rights with respect to new common
stock or securities convertible into common stock issued by us, excluding
securities issued in a public offering, upon the exercise of employee stock
options, warrants or conversion rights, or in connection with acquisitions,
financing capital projects or the incurrence of indebtedness, and rights to
participate with the Shareholders in a sale of their shares. Childs generally
may not sell its shares except to its affiliates, another of our shareholders or
in a public sale. The transfer restrictions in the Investors Agreement will
terminate upon the earliest of our initial public offering, a Change of Control
or December 23, 2003.
 
    The Shareholders are obligated to sell their shares of our common stock,
Class D Preferred Stock and Class E Preferred Stock to any unaffiliated party
pursuant to an agreement which
 
    - treats equally, on an "as-if-converted" basis, the common value of all
      holders of our common stock, Class D Preferred Stock and Class E Preferred
      Stock,
 
    - is approved by our board of directors as fair to all stockholders, and
 
    - is approved by our stockholders holding 50.1% of its outstanding common
      stock, calculated on an "as-if-converted" basis.
 
    Notwithstanding the foregoing, the Shareholders will not be obligated to
sell any shares of Class D Preferred Stock or Class E Preferred Stock unless
such holder receives cash consideration at least equal to the liquidation
preference of such Class D or Class E Preferred Stock, and will not be obligated
to sell any shares of our common stock unless all shares of Class D Preferred
Stock and Class E Preferred Stock then held by Childs are also sold in the
transaction.
 
    The Shareholders will have the right to participate pro rata in certain
sales of our outstanding common stock, Class D Preferred Stock and Class E
Preferred Stock by any other stockholder, except in the case of
 
    - the Dobson Partnership's sale of our capital stock for $25.0 million or
      less, together with accrued but unpaid dividends thereon,
 
    - the sale of any capital stock issued by us in connection with the Sygnet
      acquisition, or
 
    - transfers made after an initial public offering.
 
    The right to participate in such sale is pro rata based upon a fraction, the
numerator of which is the value of such shareholder's Class A Common Stock and
Class E Preferred Stock (valued at its liquidation preference), and the
denominator of which is the value of all outstanding Class A Common Stock.
 
CLASS F PREFERRED STOCK
 
    As part of the Sygnet Financing, certain former shareholders of Sygnet
purchased 30,000 shares of the Company's Class F Preferred Stock. The following
summary of the Class F Preferred Stock does not purport to be complete and is
qualified in its entirety by reference to the certificate of designation.
 
                                      170
<PAGE>
    CLASS F PREFERRED STOCK CERTIFICATE OF DESIGNATION.  The certificate of
designation for the Class F Preferred Stock (the "Class F Preferred Stock
Certificate of Designation") provides for the following rights, including voting
rights, preferences and powers:
 
    VOTING RIGHTS.  Except as otherwise provided by law, the shares of Class F
Preferred Stock have no voting rights except to elect one person to our Board of
Directors if a voting rights triggering event occurs with respect to the Class F
Preferred Stock.
 
    DIVIDENDS.  Dividends on the Class F Preferred Stock are payable in cash or,
at our option, in additional shares of Class F Preferred Stock. Cumulative
dividends on each share of Class F Preferred Stock accrue at the annual rate of
16% on the sum of the $1,000 per share liquidation value, and all accumulated
and unpaid dividends ("Class F Accrued Dividends") from the date of issuance,
compounded annually, are payable in cash out of funds legally available therefor
on January 15, April 15, July 15 and October 15, commencing January 15, 1999.
 
    The Financing Agreements limit, and if the exchange debentures are issued
for the Senior Preferred Stock and if Exchange Debentures are issued for the
Preferred Stock, the respective exchange debenture indentures will limit, and
for the foreseeable future effectively prohibit, the payment of cash dividends
on the Class F Preferred Stock.
 
    The Class F Preferred Stock Certificate of Designation prohibits the

SENIOR EXCHANGEABLE PREFERRED STOCK DUE 2009
    
 
   
    We expect to issue 170,000 shares of our 13% Senior Exchangeable Preferred
Stock due 2009 that will have an aggregate liquidation preference of $170.0
million. The terms of our Senior Exchangeable Preferred Stock due 2009 are
expected to be substantially similar to the terms of our Senior Preferred Stock
and Preferred Stock, as are the terms of the exchange debentures issuable, at
our option, in exchange for our Senior Exchangeable Preferred Stock due 2009.

due 2009 is expected to provide for the following rights, including voting
rights, preferences and powers:
    
 
   
    RANKING.  The Senior Exchangeable Preferred Stock due 2009 will rank senior
to the Other Preferred Stock, equal with the Senior Preferred Stock and
Preferred Stock, and junior to our capital stock we may issue in the future, the
terms of which expressly provide that such stock will rank senior to the Senior
Exchangeable Preferred Stock due 2009.
    
 
   
    VOTING RIGHTS.  The holder of Senior Exchangeable Preferred Stock due 2009
will have voting rights substantially similar to the voting rights provided to
the Senior Preferred Stock and Preferred Stock. See "Description of the
Preferred Stock--Voting Rights."
    
 
   
    DIVIDENDS.  The holders of Senior Exchangeable Preferred Stock due 2009 will
be entitled to receive cumulative dividends at the annual rate of 13% of the
$1,000 per share liquidation preference, as and when declared by the Board of
Directors. We may pay dividends in cash or in additional fully paid and
nonassessable shares of Senior Preferred Stock having a liquidation preference
equal to the amount of such dividends. After May 1, 2004, we must pay only cash
dividends. We may cash dividends on our Senior Exchangeable Preferred Stock due
2009 only if we contemporaneously declare and pay dividends on the Senior
Preferred Stock and Preferred stock.
    
 
   
    REDEMPTION.  We must redeem the Senior Exchangeable Preferred Stock due 2009
on May 1, 2009, subject to the legal availability of funds therefor, at 100% of

accrued and unpaid dividends, with net proceeds from a sale of our common stock
if at least 65% of the aggregate liquidation preference amount of the Senior
Exchangeable Preferred Stock due 2009 originally issued remain outstanding.
    
 
   
    OPTIONAL EXCHANGE.  We way exchange the Senior Exchangeable Preferred Stock
due 2009 in whole, but not in part, into our exchange debentures. Our exchange
rights are substantially similar to our exchange rights with respect to the

Stock--Exchange."
    
 
   
    CHANGE OF CONTROL.  Upon a change of control, we will be required to make an
offer to purchase our outstanding Senior Exchangeable Preferred Stock due 2009
at a purchase price equal to 100% of its liquidation preference plus unpaid
dividends. Change of control means, with respect to the Senior Exchangeable
Preferred Stock due 2009, such time as:
    
 
   
    - a shareholder becomes the beneficial owner of more than 35% of the total
      voting power of our stock, on a fully diluted basis, and such ownership
      represents a greater percentage of the total voting power of our voting
      stock, on a fully diluted basis, than is held by Everett Dobson and his
      affiliates on such date.
    
 
   
    - individuals who on the issue date of such Senior Exchangeable Preferred
      Stock due 2009 constituted the Board of Directors, together with any new
      directors whose election by the Board of Directors or whose nomination for
      election by our stockholders was approved by a vote of at least a majority
      of the members of the Board of Directors then in office who either were
      members of the Board of Directors on the issue date or whose election or
      nomination for election was previously so approved, cease for any reason
      to constitute a majority of the members of the Board of Directors then in
      office.
    
 
   
    RESTRICTED SUBSIDIARIES.  All of our subsidiaries are restricted
subsidiaries under the Senior Exchangeable Preferred Stock due 2009, except for
Logix and Dobson Tower, and their subsidiaries, which have been designated as
unrestricted.
    
 
   
    REGISTRATION REQUIREMENTS.  We will be required to file and cause to become
effective a registration statement with respect to a registered offer to
exchange the Senior Exchangeable Preferred Stock due 2009 for an issue of our
Senior Exchangeable Preferred Stock due 2009 with identical terms. If we do not
complete the exchange offer within 180 days after its issue date, the dividend
rate on our Senior Exchangeable Preferred Stock due 2009 will be increased by
 .5% per annum until we complete the offering. Under certain circumstances, we
may be required to effect a shelf registration statement with respect to the
resale of the Senior Exchangeable Preferred Stock due 2009.

                       FEDERAL INCOME TAX CONSIDERATIONS
    
 
   
    The following summary describes the anticipated material U.S. federal income
tax consequences of the purchase, ownership and disposition of the Preferred
Stock and the Exchange Debentures. Except where we note otherwise, the following
discussion deals only with Preferred Stock and Exchange Debentures held as
capital assets by United States Holders and does not deal with special
situations, such as those of dealers in securities or currencies, financial
institutions, life insurance companies, persons holding Preferred Stock or
Exchange Debentures as a part of a hedging or conversion transaction or a
straddle or United States Holders whose "functional currency" is not the U.S.
dollar. Furthermore, the discussion below is based upon the provisions of the
U.S. Internal Revenue Code of 1986, as amended (the "Code"), and regulations,
including final Treasury regulations addressing debt instruments issued with OID
(the "OID Regulations"), rulings and judicial decisions under these regulations
to the date. We also note that such authorities may be repealed, revoked or
modified, possibly with retroactive effect, so as to result in U.S. federal
income tax consequences different from those discussed below. 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 PREFERRED STOCK OR THE EXCHANGE DEBENTURES.
    
 
   
TAX CONSEQUENCES TO UNITED STATES HOLDERS
    
 
   
    We define the term "United States Holder" to mean a beneficial owner that is
a citizen or resident of the United States, a corporation, partnership (unless
Treasury regulations provide otherwise) or other entity that was created or
organized in or under the laws of the United States or any political subdivision
thereof, an estate the income of which is subject to U.S. federal income
taxation regardless of its source or a trust if both
    
 
   
    - a court within the United States is able to exercise primary supervision
      over the administration of such trust, and
    
 
   
    - one or more United States persons have the authority to control all
      substantial decisions of such trust.
    
 
   
    An individual may, subject to certain exceptions, be deemed to be a
resident, as opposed to a non-resident alien, of the United States by virtue of
being present in the United States on at least 31 days in the calendar year and
for an aggregate of at least 183 days during a three-year period ending in the
current calendar year. A "Non-United States Holder" is a holder that is not a
United States Holder.
    
 
   
DISTRIBUTIONS ON THE PREFERRED STOCK
    
 
   
    Distributions of cash or of additional Preferred Stock on the Preferred
Stock will be treated as dividends to United States Holders to the extent of our
current and accumulated earnings and profits as determined under U.S. federal
income tax principles. The amount of our earnings and profits at any time will
depend upon our future actions and financial performance. The amount of a
distribution of additional Preferred Stock will equal the fair market value of
the Preferred Stock that we distribute on the date of the distribution. To the
extent that the amount of a distribution on the Preferred Stock exceeds our
current and accumulated earnings and profits, such distributions will be treated
as a nontaxable return of capital and will be applied against and reduce the
adjusted tax basis of the Preferred Stock in the hands of each United States
Holder, but not below zero, thus increasing the amount of any gain or reducing
the amount of any loss which would otherwise be recognized by such United States
Holder upon the sale or other taxable disposition of such Preferred Stock. The
amount of any distribution that exceeds the adjusted tax basis of the Preferred
Stock in the hands of the United States Holder will be treated as capital gain
and will be either long-term or short-term capital gain depending on the United
States Holder's holding period for the Preferred Stock. The initial tax basis of
additional Preferred Stock in the hands of a holder who received such additional
Preferred Stock as a distribution on Preferred Stock will equal the fair market
value of such additional Preferred Stock at the time of distribution.
    
 
                                      175
<PAGE>
   
    We presently do not have any current or accumulated earnings and profits as
determined under U.S. federal income tax principles and we are unlikely to have
current or accumulated earnings and profits in the foreseeable future. As a
result, until such time as we do have earnings and profits, distributions of
cash and additional Preferred Stock on the Preferred Stock will not be treated
as dividends, and instead will constitute a nontaxable return of capital that
reduces a holder's adjusted tax basis in the Preferred Stock. In the case of
distributions of additional Preferred Stock, such basis reduction should be
offset on an overall standpoint by a corresponding amount of tax basis for a
holder in the additional Preferred Stock. A United States Holder would recognize
gain to the extent that any distribution were to exceed current or accumulated
earnings and profits and the adjusted tax basis of the holder in the Preferred
Stock.
    
 
   
    Under Section 243 of the Code, corporate United States Holders generally
will be able to deduct 70% of the amount of any distribution qualifying as a
dividend. There are, however, many exceptions and restrictions relating to the
availability of such dividends-received deduction. Section 246A of the Code
reduces the dividends-received deduction allowed to a corporate United States
Holder that has indebtedness "directly attributable" to its investment in
portfolio stock. Section 246(c) of the Code requires that in order to be
eligible for the dividends-received deduction, a corporate United States Holder
generally must hold the shares of Preferred Stock for a 46-day minimum holding
period or a 91-day period in certain circumstances. A taxpayer's holding period
for these purposes is suspended during any period in which a United States
Holder has certain options or contractual obligations with respect to
substantially identical stock or holds one or more other positions with respect
to substantially identical stock that diminishes the risk of loss from holding
the Preferred Stock. A recent legislative enactment modified the manner in which
the 46- or 91-day minimum holding period is determined, and requires that the
applicable holding period be determined with respect to each dividend payment
date on an "unhedged" basis.
    
 
   
    Under Section 1059 of the Code, a corporate United States Holder is required
to reduce its tax basis (but not below zero) in the Preferred Stock by the
nontaxed portion of any "extraordinary dividend" if such stock has not been held
for more than two years before the earliest of the date such dividend is
declared, announced or agreed to. Generally, the nontaxed portion of an
extraordinary dividend is the amount excluded from income by operation of the
dividends-received deduction provisions of Section 243 of the Code. An
extraordinary dividend on the Preferred Stock generally would be a dividend that
    
 
   
    - equals or exceeds 5% of the corporate United States Holder's adjusted tax
      basis in the Preferred Stock, generally treating all dividends received by
      the United States Holder and having ex-dividend dates within an 85 day
      period as one dividend, or
    
 
   
    - exceeds 20% of the corporate United States Holder's adjusted tax basis in
      such Preferred Stock; generally treating all dividends received by the
      United States Holder having ex-dividend dates within a 365-day period as
      one dividend.
    
 
   
    In determining whether a dividend paid on the Preferred Stock is an
extraordinary dividend, a corporate United States Holder may elect to substitute
the fair market value of the Preferred Stock for such United States Holder's tax
basis for purposes of applying these tests, provided such fair market value is
established to the satisfaction of the Secretary of Treasury as of the day
before the ex-dividend date. An extraordinary dividend also includes any amount
treated as a dividend in the case of a redemption that is either non-pro rata as
to all stockholders or in connection with our partial liquidation, regardless of
the stockholder's holding period and regardless of the size of the dividend. If
any part of the nontaxed portion of an extraordinary dividend is not applied to
reduce the corporate United States Holder's tax basis as a result of the
limitation on reducing such basis below zero, such part will be treated as gain
from the sale or exchange of the Preferred Stock, which must be recognized at
the time when the extraordinary dividend is paid. Special rules exist with
respect to "qualified preferred dividends." A qualified preferred dividend is
any fixed dividend payable with respect to any share of stock which
    
 
   
    - provides for fixed preferred dividends payable not less frequently than
      annually, and
    
 
                                      176
<PAGE>
   
    - is not in arrears as to dividends at the time the United States Holder
      acquires such stock.
    
 
   
    A qualified preferred dividend does not include any dividend payable with
respect to any share of stock if the actual rate of return of such stock exceeds
15%. Section 1059 does not apply to qualified preferred dividends if the
corporate United States Holder holds such stock for more than five years. If the
United States Holder disposes of such stock before it has been held for more
than five years, the amount subject to extraordinary dividend treatment with
respect to qualified preferred dividends is limited to the excess of the actual
rate of return over the stated rate of return. Actual or stated rates of return
are the actual or stated dividends expressed as a percentage of the lesser of
    
 
   
    - the United States Holder's tax basis in such stock, or
    
 
   
    - the liquidation preference of such stock. Corporate United States Holders
      are urged to consult their tax advisors with respect to the possible
      application of Section 1059 to their ownership and disposition of the
      Preferred Stock.
    
 
   
    The portion of the dividends received that a corporate United States Holder
deducts in computing taxable income may affect a corporate United States
Holder's liability for alternative minimum tax. This results from the fact that
corporate stockholders are required to increase alternative minimum taxable
income by 75% of the excess of current earnings (with certain adjustments) over
alternative minimum taxable income (determined without regard to earnings and
profit adjustments or the alternative tax net operating loss deduction).
Prospective corporate investors should be aware that distributions we pay in
respect of the Preferred Stock (whether payable in cash or additional shares of
Preferred Stock) will not be eligible for the dividends-received deduction under
Section 243 of the Code until such time as Dobson has current or accumulated
earnings and profits.
    
 
   
REDEMPTION PREMIUM
    
 
   
    Under Section 305 of the Code and the applicable Treasury regulations, if
the redemption price of Preferred Stock exceeds its issue price, the difference
("redemption premium") may be taxable as a constructive distribution of
additional Preferred Stock to the United States Holder and treated as a dividend
to the extent of our current and accumulated earnings and profits and otherwise
subject to the treatment described above for distributions, over a certain
period. Because the Preferred Stock provides for our optional right of
redemption at prices in excess of the issue price, United States Holders could
be required to recognize such redemption premium under a constant interest rate
method similar to that described below for accruing OID (see "--Original Issue
Discount") if, based on all of the facts and circumstances, the optional
redemption is more likely than not to occur. If stock may be redeemed at more
than one time, the time and price at which such redemption is most likely to
occur must be determined based on all of the facts and circumstances. Applicable
Treasury regulations provide a "safe harbor" under which a right to redeem will
not be treated as more likely than not to occur if
    
 
   
    - the issuer and the holder are not related within the meaning of the
      Treasury regulations,
    
 
   
    - there are no plans, arrangements or agreements that effectively require or
      are intended to compel the issuer to redeem the stock (disregarding, for
      this purpose, a separate mandatory redemption) and
    
 
   
    - exercise of the right to redeem would not reduce the yield of the stock,
      as determined under the Treasury regulations.
    
 
   
    Further, the Treasury regulations provide that such redemption premium is
not taxable as a constructive distribution if it is solely in the nature of a
penalty for premature redemption. A redemption premium is solely in the nature
of a penalty for premature redemption if it is paid as a result of changes in
economic or market conditions over which neither the issuer nor the holder have
control. Regardless of whether the optional redemption is more likely than not
to occur or whether the redemption premium is solely in the
    
 
                                      177
<PAGE>
   
nature of a penalty for premature redemption, constructive dividend treatment
will not result if the redemption premium does not exceed a de minimis amount.
Based on the Treasury regulations, we intend to take the position that the
existence of our optional redemption right does not result in a constructive
distribution to the United States Holders.
    
 
   
    Further, because the Preferred Stock provides for an optional right of the
United States Holders to require us to acquire the Preferred Stock at a price
equal to 101% of the liquidation value upon a Change of Control, United States
Holders could be required to recognize such redemption premium under the
constant yield method discussed above unless, very generally, the likelihood of
redemption is remote. Here, too, regardless of whether the likelihood of
redemption is remote, constructive dividend treatment will not result if the
redemption premium does not exceed a de minimis amount of 1/4 of 1% of the
stated redemption price at maturity multiplied by the number of complete years
to maturity. We intend to take the position that the existence of United States
Holders' optional redemption right does not result in a constructive
distribution to the Holders.
    
 
   
    Moreover, the Preferred Stock provides for a mandatory redemption at a
redemption price equal to the liquidation value of the Preferred Stock, plus
accrued and unpaid dividends. If at the time of issuance of Preferred Stock,
there is no intention for dividends to be paid currently, the IRS may treat the
payment of such dividends on redemption as disguised redemption premium subject
to the constant yield rules discussed above. Dividends on the Preferred Stock
are payable in cash or, on or prior to January 15, 2003, in additional shares of
Preferred Stock. We intend to pay all such dividends currently. Thus, while the
appropriate treatment of unpaid cumulative dividends has not yet been addressed
in Treasury regulations and no assurance can be given as to the outcome of such
guidance, we intend to take the position that the terms of the mandatory
redemption should not result in a constructive distribution to the United States
Holders.
    
 
   
    Finally, in the event that additional Preferred Stock is distributed on the
Preferred Stock and such additional Preferred Stock has a fair market value at
the time of distribution that is less than its redemption price, such additional
Preferred Stock would have a redemption premium that may be taxable as a
constructive distribution of additional stock to a United States Holder, treated
as a dividend to the extent of our current and accumulated earnings and profits,
under the constant yield method over the term of such additional Preferred
Stock.
    
 
   
REDEMPTION AND EXCHANGE FOR EXCHANGE DEBENTURES
    
 
   
    A redemption of shares of the Preferred Stock for cash or an exchange of the
Preferred Stock for Exchange Debentures will be a taxable transaction on which a
United States Holder generally will recognize capital gain or loss (except to
the extent of amounts received on the exchange that are attributable to declared
dividends, which will be treated in the same manner as distributions described
above) provided that the redemption
    
 
   
    - results in complete termination of the holder's stock interest in us or
    
 
   
    - results in a "meaningful reduction" in a United States Holder's stock
      interest in us. Whether a redemption will result in a meaningful reduction
      depends on the particular holder's facts and circumstances. In determining
      whether a United States Holder's interest in us has been reduced or
      terminated, the holder is deemed, under the constructive ownership rules
      of Section 302(c) of the Code, to own any shares of our stock that are
      owned, or deemed owned, by certain related persons and entities and any
      shares that such holder, or related person or entity, has the right to
      acquire by exercise of an option. If the redemption of the Preferred Stock
      does not result in a complete termination or meaningful reduction, as
      described above, the transaction will be treated as a distribution of cash
      or Exchange Debentures, as the case may be. The amount of such
      distribution will be measured by the amount of cash received by the United
      States Holder or the "issue price," as defined below, of the Exchange
      Debentures received by the United States Holder, and such
    
 
                                      178
<PAGE>
   
      distribution will be treated in the same manner as distributions described
      above. However, corporate holders should be aware that to the extent such
      distribution is treated as a dividend it may be an extraordinary dividend
      under Section 1059 of the Code. If the redemption of the Preferred Stock
      does result in a complete termination or meaningful reduction, the gain or
      loss recognized on such exchange will generally be equal to the difference
      between the amount realized by the United States Holder of the Preferred
      Stock and such United States Holder's adjusted tax basis in the Preferred
      Stock surrendered in the redemption.
    
 
   
    In the case of a redemption for cash, the amount realized will be the cash
received on the redemption. In the case of an exchange of Preferred Stock for
Exchange Debentures, the amount realized on receipt of the Exchange Debentures
will be equal to the "issue price" of the Exchange Debentures. Thus, the amount
realized on the exchange will be equal to the issue price of the Exchange
Debentures plus any cash received on the exchange (other than cash received with
respect to declared dividends). If, as of the exchange date, either the Exchange
Debentures or the Preferred Stock are traded on an established securities market
on or at any time during the 60 day period ending 30 days after the exchange
date, then the issue price of the Exchange Debentures would equal the fair
market value of the property so traded. If neither the Preferred Stock nor the
Exchange Debentures are so traded, the issue price of the Exchange Debentures
would be the stated principal amount of the Exchange Debentures provided that
the yield on the Exchange Debentures is equal to or greater than the "applicable
federal rate" in effect at the time the Exchange Debenture is issued. If the
yield on the Exchange Debentures is less than such applicable federal rate, its
issue price under Section 1274 of the Code would be equal to the present value
as of the issue date of all payments to be made on the Exchange Debentures,
discounted at the applicable federal rate. It cannot be determined at the
present time whether the Preferred Stock or the Exchange Debentures will be, at
the relevant time, traded on an established securities market within the meaning
of the OID Regulations or whether the yield on the Exchange Debentures will
equal or exceed the applicable federal rate.
    
 
   
SALE OR OTHER DISPOSITION OF PREFERRED STOCK
    
 
   
    A United States Holder's adjusted tax basis in the Preferred Stock will
equal the amount paid for such stock plus the fair market value of any
distributions of additional Preferred Stock and any amount included in gross
income as a constructive distribution of redemption premium, in each case under
Section 305 of the Code, as described in "--Distributions on the Preferred
Stock" and "--Redemption Premium," and reduced by the amount of any distribution
treated as a nontaxable return of capital that reduced the adjusted tax basis of
the Preferred Stock, as described in "--Distributions on the Preferred Stock."
In general, a United States Holder will recognize capital gain or loss upon the
sale or other taxable disposition of Preferred Stock based upon the difference
between the amount realized in such sale or other disposition, and the holder's
adjusted tax basis in the Preferred Stock. Such gain or loss will be either
long-term or short-term capital gain depending on the United States Holder's
holding period for the Preferred Stock at the time of redemption, sale, exchange
or retirement of the Preferred Stock. In the case of an individual United States
Holder, any such capital gain will be taxable at various preferential rates
depending on the extent to which such United States Holder's holding period for
the Preferred Stock exceeds one year. The deduction of capital losses is subject
to certain limitations. Prospective investors should consult their own tax
advisors in this regard.
    
 
   
    Depending upon a United States Holder's particular circumstances, the tax
consequences of holding Exchange Debentures may be less advantageous than the
tax consequences of holding Preferred Stock because, for example, payments of
interest on the Exchange Debentures will not be eligible for any
dividends-received deduction that may be available to corporate United States
Holders, subject to our having earnings and profits, and because, as discussed
below, the Exchange Debentures will be issued with OID.
    
 
                                      179
<PAGE>
   
PAYMENTS OF INTEREST AND OID ON THE EXCHANGE DEBENTURES
    
 
   
    The tax treatment of the Exchange Debentures will turn on whether or not
they are issued with OID. Exchange Debentures issued on or before January 15,
2003 likely will be treated as having been issued with OID. Exchange Debentures
issued after January 15, 2003 will not be issued with OID unless, generally,
their stated redemption price at maturity, as defined below, exceeds their issue
price, as defined above.
    
 
   
    Because we have the option through January 15, 2003 to pay interest on the
Exchange Debentures by issuing additional Exchange Debentures, Exchange
Debentures (including Exchange Debentures issued in exchange for Preferred
Stock) issued prior to that date likely will be treated as issued with OID.
Accordingly, the stated interest on an Exchange Debenture would not be treated
as interest for U.S. federal income tax purposes, but instead will be subject to
the OID rules described below. In the case of Exchange Debentures that are not
issued with OID, payments of stated interest generally will be includible in a
United States Holder's income as ordinary income under the holder's regular
method of accounting.
    
 
   
ORIGINAL ISSUE DISCOUNT
    
 
   
    The Exchange Debentures, if issued in exchange for Preferred Stock, may be
issued with OID, as further discussed below. Holders of such Exchange Debentures
should be aware that they generally must include OID in gross income for U.S.
federal income tax purposes on an annual basis under a constant yield accrual
method. As a result, Holders will include OID in income in advance of the
receipt of cash attributable to that income. However, United States Holders of
Exchange Debentures issued with OID generally will not be required to include
separately in income cash payments received on such Exchange Debentures, even if
denominated as interest, to the extent such payments do not constitute qualified
stated interest (as defined below). The Exchange Debentures issued with OID will
be referred to as "OID Debentures." We will report to United States Holders of
any Exchange Debentures which are issued with OID, on a timely basis the
reportable amount of OID and interest income based on its understanding of
applicable law.
    
 
   
    The amount of OID, if any, on a debt instrument is the excess of its "stated
redemption price at maturity" over its "issue price" subject to a statutorily
defined de minimis exception. The issue price of a debt instrument issued for
cash is equal to the first price, excluding sales to bond houses and brokers, at
which a substantial amount of such debt instruments were sold. The "stated
redemption price at maturity" of a debt instrument is the sum of its principal
amount plus all other payments required thereunder, other than payments of
"qualified stated interest" (defined generally as stated interest that is
unconditionally payable in cash or in property (other than the debt instruments
of the issuer), at least annually at a single fixed rate that appropriately
takes into account the length of intervals between payments).
    
 
   
    Because we have the option through January 15, 2003 to pay interest on the
Exchange Debentures by issuing additional Exchange Debentures, with respect to
any Exchange Debentures issued on or prior to that date, none of the stated
interest would be treated as qualified stated interest unless under special
rules for interest holidays the amount of OID is treated as de minimis. Any
Exchange Debentures so issued would be treated as having been issued with OID
equal to the excess of their stated redemption price at maturity, which will be
equal to the sum of the principal amount plus all payments of stated interest,
over their issue price, which will be as described under "--Redemption and
Exchange for Exchange Debentures" above. Any additional Exchange Debentures
issued in lieu of cash would not be treated as debt instruments separate from
the Exchange Debentures upon which they were issued, but instead are aggregated
with such Exchange Debentures for OID purposes.
    
 
   
    The right to issue additional Exchange Debentures in lieu of paying cash
interest through January 15, 2003 is treated for purposes of the OID provisions
of the Code as an option to defer the interest payments on the Exchange
Debentures. The OID regulations provide that in the case of a debt instrument
that provides the issuer with an unconditional option or options exercisable
during the term of the debt instrument that, if exercised, require payments to
be made on the debt instrument under an alternative
    
 
                                      180
<PAGE>
   
payment schedule, the yield and maturity of such debt instrument for purposes of
calculating OID are determined by assuming the issuer exercises or does not
exercise the option in a manner that minimizes the yield on the debt instrument.
    
 
   
    If the issue price of the Exchange Debentures is equal to their principal
amount, the yield to maturity of the Exchange Debentures, if the option to pay
interest with additional Exchange Debentures is exercised, will be no less than
the yield to maturity would be if the option is not exercised. Accordingly, for
purposes of calculating OID, it would be assumed that we will not exercise the
option because exercise of the option will not minimize the yield. If the option
were in fact subsequently exercised and additional Exchange Debentures were
issued by us in lieu of cash, such additional Exchange Debentures would be
aggregated with the Exchange Debentures upon which they were issued, and OID
would be recalculated for the remainder of the term of the Exchange Debentures
based upon a stated redemption price at maturity which includes the amount of
all payments due under the additional Exchange Debentures. As a result of such
exercise, United States Holders of Exchange Debentures would include OID in
income in advance of the receipt of cash, regardless of such United States
Holders' regular methods of accounting.
    
 
   
    If the issue price of the Exchange Debentures is less than their principal
amount, the yield to maturity of the Exchange Debentures, if the option to pay
interest with additional Exchange Debentures is exercised, will be less than the
yield to maturity if the option is not exercised. Accordingly, for purposes of
calculating OID, it would be assumed that we will exercise the option because to
do so will minimize the yield. If we subsequently makes a cash payment instead
of exercising its option to issue an additional Exchange Debenture, the cash
payment made will be treated as a prepayment of the Exchange Debentures,
partially retiring such Exchange Debentures on a pro rata basis on the date of
such payment. Such retirement would be a taxable exchange to the Holder of the
Exchange Debenture.
    
 
   
    If the Exchange Debentures are issued after January 15, 2003, we would not
have the option to pay interest with additional Exchange Debentures. In such
event,
    
 
   
    - all interest payments on any Exchange Debenture issued will be qualified
      stated interest,
    
 
   
    - the stated redemption price at maturity of any Exchange Debenture will be
      equal to its principal amount, and
    
 
   
    - any Exchange Debenture will therefore be issued with OID only to the
      extent its principal amount exceeds its issue price by more than a de
      minimis amount.
    
 
   
    The amount of OID includible in income by the initial United States Holder
of an OID Debenture is the sum of the "daily portions" of OID with respect to
the OID Debenture for each day during the taxable year or portion of the taxable
year in which such United States Holder held such OID Debenture ("accrued OID").
The daily portion is determined by allocating to each day in any "accrual
period" a pro rata portion of the OID allocable to that accrual period. The
"accrual period" for an OID Debenture may be of any length and may vary in
length over the term of the OID Debenture, provided that each accrual period is
no longer than one year and each scheduled payment of principal or interest
occurs on the first day or the final day of an accrual period. The amount of OID
allocable to any accrual period is an amount equal to the excess, if any, of
    
 
   
    - the product of the OID Debenture's adjusted issue price at the beginning
      of such accrual period and its yield to maturity (determined on the basis
      of compounding at the close of each accrual period and properly adjusted
      for the length of the accrual period, over
    
 
   
    - the sum of any qualified stated interest allocable to the accrual period.
    
 
   
    OID allocable to a final accrual period is the difference between the amount
payable at maturity (other than a payment of qualified stated interest) and the
adjusted issue price at the beginning of the final accrual period. The
calculation of OID for an initial short accrual period may be determined using
any reasonable method. The "adjusted issue price" of an OID Debenture at the
beginning of any accrual
    
 
                                      181
<PAGE>
   
period is equal to its issue price increased by the accrued OID for each prior
accrual period (determined without regard to the amortization of any acquisition
or bond premium, as described below) and reduced by any payment made on such OID
Debenture, other than qualified stated interest, on or before the first day of
the accrual period.
    
 
   
    Exchange Debentures may be redeemed prior to their stated maturity at our
option. For purposes of computing the yield of such instrument, we will be
deemed to exercise or not exercise its option to redeem the OID Debentures in a
manner that minimizes the yield on the OID Debentures. It is not anticipated
that our ability to redeem prior to stated maturity would affect the yield of
such instrument.
    
 
   
    In the event of a change of control, we will be required to offer to
repurchase all of the Exchange Debentures. The right of holders to require
repurchase upon a change of control will not affect the yield or maturity date
of the Exchange Debentures unless, based on all the facts and circumstances as
of the issue date, it is more likely than not that such an event giving rise to
the repurchase will occur. We do not intend to treat the change of control
provisions of the Exchange Debentures as affecting the computation of the yield
to maturity of any Exchange Debentures.
    
 
   
    United States Holders may elect to treat all interest on any Exchange
Debenture as OID and calculate the amount to be included in gross income under
the constant yield method described above. For the purposes of this election,
interest includes stated interest, acquisition discount, OID, de minimis OID,
market discount, de minimis market discount and unstated interest, as adjusted
by any amortizable bond premium or acquisition premium. The election is to be
made for the taxable year in which the United States Holder acquired the
Exchange Debenture, and may not be revoked without the consent of the U.S.
Internal Revenue Service. United States Holders should consult with their own
tax advisors about this election.
    
 
   
MARKET DISCOUNT ON RESALE OF EXCHANGE DEBENTURES
    
 
   
    If a United States Holder acquires an Exchange Debenture, other than an OID
Debenture, for an amount less than its stated redemption price at maturity or,
in the case of an OID Debenture, for an amount that is less than its adjusted
issue price, the amount of the difference will be treated as "market discount"
for U.S. federal income tax purposes, unless such difference is less than a
specified de minimis amount. Under the market discount rules, a United States
Holder will be required to treat any principal payment on an Exchange Debenture,
or any gain on the sale, exchange, retirement or other disposition of an
Exchange Debenture as ordinary income to the extent of the market discount which
has not previously been included in income and is treated as having accrued on
such Exchange Debenture at the time of such payment or disposition. In addition,
the United States Holder may be required to defer, until the maturity of the
Exchange Debenture or its earlier disposition in a taxable transaction, the
deduction of all or a portion of the interest expense on any indebtedness
incurred or continued to purchase or carry such Exchange Debenture.
    
 
   
    Any market discount will be considered to accrue ratably during the period
from the date of acquisition to the maturity date of the Exchange Debenture,
unless the United States Holder elects to accrue on a constant interest method.
A United States Holder of an Exchange Debenture may elect to include market
discount in income currently as it accrues (on either a ratable or constant
interest method), in which case the rule described above regarding deferral of
interest deductions will not apply. This election to include market discount in
income currently, once made, applies to all market discount obligations acquired
on or after the first taxable year to which the election applies and may not be
revoked without the consent of the Internal Revenue Service.
    
 
   
    ACQUISITION PREMIUM; AMORTIZABLE BOND PREMIUM
    
 
   
    A United States Holder that purchases an Exchange Debenture for an amount
that is greater than its adjusted issue price but equal to or less than the sum
of all amounts payable on the Exchange Debenture
    
 
                                      182
<PAGE>
   
after the purchase date, other than qualified stated interest, will be
considered to have purchased such Exchange Debenture at an "acquisition
premium." Under the acquisition premium rules, the amount of OID, if any, which
such United States Holder must include in its gross income with respect to such
Exchange Debenture for any taxable year will be reduced by the portion of such
acquisition premium properly allocable to such year.
    
 
   
    If immediately after the time the Preferred Stock is exchanged for Exchange
Debentures or immediately after the time a subsequent United States Holder
acquires Exchange Debentures, the United States Holder's tax basis in any such
Exchange Debenture exceeds the sum of all amounts payable on the Exchange
Debenture after the exchange date or purchase date, other than qualified stated
interest, such excess may constitute "premium" and such United States Holder
will not be required to include any OID in income. A United States Holder
generally may elect to amortize bond premium over the remaining term of the
Exchange Debenture on a constant yield method. The amount amortized in any year
will be treated as a reduction of the United States Holder's interest income
from the Exchange Debenture. Bond premium on an Exchange Debenture held by a
United States Holder that does not make such an election will decrease the gain
or increase the loss otherwise recognized on disposition of the Exchange
Debenture. The election to amortize bond premium on a constant yield method once
made applies to all debt obligations held or subsequently acquired by the
electing United States Holder on or after the first day of the first taxable
year to which the election applies and may not be revoked without the consent of
the Internal Revenue Service.
    
 
   
    REDEMPTION, SALE OR EXCHANGE OF EXCHANGE DEBENTURES
    
 
   
    The adjusted tax basis of a United States Holder who receives Exchange
Debentures in exchange for Preferred Stock will, in general, be equal to the
issue price of such Exchange Debentures, increased by OID and market discount
previously included in income by the United States Holder and reduced by any
amortized premium and any cash payments on the Exchange Debentures other than
qualified stated interest. Upon the redemption, sale, exchange or retirement of
an Exchange Debenture, a United States Holder will recognize gain or loss equal
to the difference between the amount realized upon the redemption, sale,
exchange or retirement (less any accrued qualified stated interest, not
previously taken into account, which will be taxable as such) and the adjusted
tax basis of the Exchange Debenture. Such gain or loss will be capital gain or
loss and will be long-term capital gain or loss if at the time of redemption,
sale, exchange or retirement the Exchange Debenture has been held for more than
one year. In the case of an individual United States Holder, any such capital
gain will be taxable at various preferential rates depending on the extent to
which such United States Holder's holding period for the Exchange Debenture
exceeds one year. The deduction of capital losses is subject to certain
limitations. Prospective investors should consult their own tax advisors in this
regard.
    
 
   
    APPLICABLE HIGH YIELD DISCOUNT OBLIGATIONS
    
 
   
    If the yield-to-maturity on OID Debentures equals or exceeds the sum of
    
 
   
    - the "applicable federal rate" (as determined under Section 1274(d) of the
      Code) in effect for the month in which the OID Debentures are issued (the
      "AFR") and
    
 
   
    - 5% and the OID on such OID Debentures is "significant",
    
 
   
    the OID Debentures will be considered "applicable high yield discount
obligations" ("AHYDOs") under Section 163(i) of the Code. OID is significant if
the aggregate amount includible in gross income for periods before the close of
any accrual period ending more than five years after the issue date exceeds the
sum of the aggregate amount of interest to be paid before the close of such
accrual period plus the product of the issue price and the yield to maturity. If
the OID Debentures are AHYDOs, Dobson will not be allowed to take a deduction
for OID accrued on the OID Debentures for U.S. federal income tax purposes
    
 
                                      183
<PAGE>
   
until such time as we actually pay such OID in cash or in other property, other
than our stock or debt or of a person deemed to be related to us under Section
453(f)(1) of the Code.
    
 
   
    Moreover, if the yield-to-maturity on the OID Debenture exceeds the sum of
    
 
   
    - the AFR and
    
 
   
    - 6%, such excess being referred to hereinafter as the "Disqualified Yield",
      the deduction for OID accrued on the OID Debentures will be permanently
      disallowed, regardless of whether we actually pay such OID in cash or in
      other property, for U.S. federal income tax purposes to the extent such
      OID is attributable to the Disqualified Yield on the OID Debentures
      ("Dividend-Equivalent Interest"). For purposes of the dividends received
      deduction, such Dividend-Equivalent Interest will be treated as a dividend
      to the extent it is deemed to have been paid out of Dobson's current or
      accumulated earnings and profits.
    
 
   
    Because the amount of OID, if any, attributable to the Exchange Debentures
will be determined at the time such Exchange Debentures are issued, and the AFR
at such time is not predictable, it is impossible to determine at the present
time whether an OID Debenture will be treated as an AHYDO.
    
 
   
    INFORMATION REPORTING AND BACKUP WITHHOLDING
    
 
   
    In general, information reporting requirements will apply to certain
payments of dividends, principal, interest, OID, and premium and to the proceeds
of sales of Exchange Debentures and Preferred Stock made to United States
Holders other than certain exempt recipients (such as corporations). A 31%
backup withholding tax will apply to such payments if the United States Holder
fails to provide a taxpayer identification number or certification of foreign or
other exempt status or fails to report in full dividend and interest income.
    
 
   
    Any amounts withheld under the backup withholding rules will be allowed as a
refund or a credit against such United States Holder's U.S. federal income tax
liability provided the required information is timely furnished to the IRS.
    
 
   
TAX CONSEQUENCES TO NON-UNITED STATES HOLDERS
    
 
   
    DISTRIBUTIONS ON THE PREFERRED STOCK
    
 
   
    Distributions received by a Non-United States Holder in respect of the
Preferred Stock, whether in cash or additional shares of Preferred Stock, to the
extent considered dividends for U.S. federal income tax purposes, generally will
be subject to U.S. federal withholding tax at a 30% rate, or a lower rate
prescribed by an applicable income tax treaty, unless such distributions are
effectively connected with a trade or business carried on by the Non-United
States Holder within the United States and, if an income tax treaty applies, are
attributable to a permanent establishment maintained by the Non-United States
Holder within the United States. For purposes of obtaining a reduced rate of
withholding under an income tax treaty, a Non-United States Holder will be
required to provide certain information concerning such holder's country of
residence and entitlement to income tax treaty benefits. A Non-United States
Holder that is eligible for a reduced rate of U.S. federal withholding tax
pursuant to an income tax treaty may obtain a refund of any excess amounts
currently withheld by timely filing an appropriate claim for refund.
    
 
   
    Dividends effectively connected with a U.S. trade or business and, if a
treaty applies, attributable to a U.S. permanent establishment generally will
not be subject to the 30% U.S. withholding tax provided that the Non-United
States Holder provides appropriate certifications (currently IRS Form W-8) to us
or our paying agent. Such effectively connected income instead will be subject
to U.S. federal income tax on a net income basis in the same manner as if the
Non-United States Holder were a resident of the United States. In addition, if
such holder is a foreign corporation, such effectively connected income may be
subject to a
    
 
                                      184
<PAGE>
   
branch profits tax equal to 30% (or such lower rate as specified by an
applicable income tax treaty) of its effectively connected earnings and profits
for the taxable year, subject to certain adjustments.
    
 
   
    Constructive distributions on the Preferred Stock may be subject to the 30%
U.S. withholding tax in the year in which the distributions are deemed to have
occurred. Prospective investors are urged to consult their own tax advisors with
respect to the application of the withholding tax rules to constructive
distributions on the Preferred Stock. See "--Tax Consequences to United States
Holders--Redemption Premium."
    
 
   
    PAYMENTS OF INTEREST AND OID ON THE EXCHANGE DEBENTURES
    
 
   
    A Non-United States Holder generally will not be subject to the 30% U.S.
federal withholding tax with respect to the payment of interest (including OID)
on an Exchange Debenture owned by a Non-United States Holder (the "Portfolio
Interest Exception"), provided that such Non-United States Holder
    
 
   
    - does not actually or constructively own 10% or more of the total combined
      voting power of all of our classes of stock entitled to vote,
    
 
   
    - is not a controlled foreign corporation that is related, directly or
      indirectly, to us through stock ownership,
    
 
   
    - is not a bank receiving OID or interest pursuant to a loan agreement
      entered into in the ordinary course of its trade or business, and
    
 
   
    - satisfies certain certification requirements (described generally below)
      designed to enable us or other withholding agent to verify that a holder
      is in fact a Non-United States Holder.
    
 
   
    To satisfy the certification requirement referred to above, the beneficial
owner of such Exchange Debenture or a financial institution that holds
customers' securities in the ordinary course of its trade or business must
provide us or our paying agent with a statement to the effect that the
beneficial owner is not a United States Holder. These requirements generally
will be met if
    
 
   
    - the beneficial owner provides his name, address and certain other
      information, and certifies under penalties of perjury that he is not a
      United States Holder (which certification may be made on an IRS Form W-8)
      or
    
 
   
    - a financial institution that holds customers' securities in the ordinary
      course of its trade or business certifies under penalties of perjury that
      such statement has been received by it and furnishes Dobson or its paying
      agent with a copy thereof.
    
 
   
    If a Non-United States Holder is engaged in a trade or business within the
United States, and interest (including OID) on an Exchange Debenture is
effectively connected with the conduct of such trade or business and, if a
treaty applies, is attributable to a permanent establishment maintained by such
Non-United States Holder in the United States, such holder will be subject to
U.S. federal income tax on such payment on a net income basis in the same manner
as if it were a United States Holder. In addition, if such holder is a foreign
corporation, it may be subject to a branch profits tax equal to 30%, or such
lower rate as specified by an applicable income tax treaty, of its effectively
connected earnings and profits for the taxable year, subject to certain
adjustments.
    
 
   
    A Non-United States Holder that is not eligible for the Portfolio Interest
Exception instead may be eligible to secure a reduced rate of withholding under
a valid income tax treaty entered into between the United States and such
Non-United States Holder's country of residence. Such a Non-United States Holder
generally will be required to provide certain certifications to us or our paying
agent in order to claim entitlement to the benefits of the applicable income tax
treaty.

    SALE OR DISPOSITION OF THE PREFERRED STOCK OR THE EXCHANGE DEBENTURES
    
 
   
    Subject to the discussion below in "--Consequences to Non-United States
Holders--FIRPTA Treatment," any gain or income realized upon the sale, exchange,
retirement or other disposition of the Preferred Stock or the Exchange
Debentures generally will not be subject to U.S. federal income tax unless
    
 
   
    - such gain or income is effectively connected with a trade or business in
      the United States of the Non-United States Holder and, if a treaty
      applies, attributable to a U.S. permanent establishment maintained by the
      Non-United States Holder, or
    
 
   
    - in the case of an individual who is a Non-United States Holder, such
      individual is present in the United States for 183 days or more in the
      taxable year of such sale, exchange, retirement or other disposition, and
      certain other conditions are met.
    
 
   
FIRPTA TREATMENT
    
 
   
    At present, we believe that we are not a U.S. real property holding company
within the meaning of Section 897(c)(2) of the Code, and that it does not expect
to become a U.S. real property holding company in the forseeable future. No
assurance can be given, however, that the IRS will not reach a different
conclusion or that our expectation for the future will not change. If we are
found to be a U.S. real property holding company, then a Non-United States
Holder of Preferred Stock may be subject to U.S. federal income tax in respect
of gain realized on the sale or other disposition of the Preferred Stock
(including an exchange for Exchange Debentures or a redemption) as if the gain
represented income effectively connected with a U.S. trade or business. A
Non-United States Holder will not be subject to such tax, however, if the
Preferred Stock is regularly traded on an established securities market at the
time of a sale or other disposition, and the holder has not owned more than 5%
of the Preferred Stock at any time during the five-year period, or shorter
holding period for the Preferred Stock, ending on the sale or disposition date.
    
 
   
    INFORMATION REPORTING AND BACKUP WITHHOLDING
    
 
   
    In general, information reporting requirements will apply to certain
payments of dividends, interest, OID and premium and to the proceeds of sales of
Exchange Debentures and Preferred Stock made to Non-United States Holders, other
than certain exempt recipients. In addition, a backup withholding tax of 31% may
apply to such payments unless the Non-United States Holder provides appropriate
certification of foreign status. Prospective Non-United States Holders should
consult their own tax advisors regarding the application of the new Treasury
regulations to an investment in the Preferred Stock and Exchange Debentures.
    
 
   
    THE FOREGOING SUMMARY DOES NOT DISCUSS ALL ASPECTS OF U.S. FEDERAL INCOME
TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR PARTICULAR CIRCUMSTANCES
AND INCOME TAX SITUATION. YOU SHOULD CONSULT YOUR OWN TAX ADVISOR AS TO THE
SPECIFIC TAX CONSEQUENCES THAT WOULD RESULT FROM THEIR PURCHASE, OWNERSHIP AND
DISPOSITION OF THE PREFERRED STOCK AND THE EXCHANGE DEBENTURES, INCLUDING THE
APPLICATION AND EFFECT OF STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE
POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.

                              PLAN OF DISTRIBUTION
 
   
    There has previously been only a limited secondary market and no public
market for the old shares. We do not intend to apply for the listing of the
Preferred Stock on a national securities exchange or for their quotation through
The Nasdaq Stock Market. The Preferred Stock is eligible for trading in the
PORTAL market. We have been advised by the Initial Purchaser that the Initial
Purchaser currently intends to make a market in the Preferred Stock; however,
the Initial Purchaser is not obligated to do so and any market making may be
discontinued by the 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 shares or the new shares will
develop. If a trading market does not develop or is not maintained, holders of
Preferred Stock may experience difficulty in reselling Preferred Stock. If a
trading market develops for the Preferred Stock, future trading prices of such
securities will depend on many factors, including, among other things,
prevailing interest rates, our 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 SHARES AS A RESULT OF MARKET MAKING
ACTIVITIES OR TRADING ACTIVITIES MAY NOT PARTICIPATE IN THE EXCHANGE OFFER.
    
 
   
    With respect to resale of new shares, based on an interpretation by the
staff of the SEC set forth in no-action letters issued to third parties, we
believe that a holder (other than a person that is our affiliate within the
meaning of Rule 405 under the Securities Act or a "broker" or "dealer"
registered under the Exchange Act) who exchanges old shares for new shares 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 shares, will be allowed to resell
the new shares to the public without further registration under the Securities
Act and without delivering to the purchasers of the new shares a prospectus that
satisfies the requirements of Section 10 thereof. However, if any holder
acquires new shares in the exchange offer for the purpose of distributing or
participating in a distribution of the new shares, such holder cannot rely on
the position of the staff of the SEC 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 us in the letter of transmittal that
 
   
    - the new shares are to be acquired by the holder in the ordinary course of
      business
    
 
   
    - the holder is not engaging and does not intend to engage in the
      distribution of the new shares, and
    
 
   
    - the holder acknowledges that, if such holder participates in the exchange
      offer for the purpose of distributing the new shares, 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 shares that were acquired for its own account as
a result of market-making activities or other trading activities (other than old
shares acquired directly from us or our affiliate) may exchange such old shares
for new shares 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 shares received by it in the
exchange offer, which prospectus delivery requirement may be satisfied by the
delivery by such Broker-Dealer of this prospectus. We have 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
    
 
                                      187
<PAGE>
   
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 shares
received by it in the exchange offer. The delivery by a Broker-Dealer of a
prospectus in connection with resales of new shares shall not be deemed to be an
admission by such Broker-Dealer that it is an underwriter within the meaning of
the Securities Act. We will not receive any proceeds from any sale of new shares
by a Broker-Dealer.
    
 
   
    New shares 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 shares 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 shares.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of
Dobson Communications Corporation:
 
    We have audited the accompanying consolidated balance sheets of Dobson
Communications Corporation (an Oklahoma corporation) and subsidiaries as of
December 31, 1997 and 1998, and the related consolidated statements of
operations, stockholders' deficit and cash flows for each of the three years in
the period ended December 31, 1998. These consolidated financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated 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 consolidated financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Dobson Communications Corporation and subsidiaries as of December 31, 1997 and
1998, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1998, in conformity with generally
accepted accounting principles.

               DOBSON COMMUNICATIONS CORPORATION AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION:
 
    Dobson Communications Corporation ("DCC" or the "Company"), through its
predecessors, was organized in 1936 as Dobson Telephone Company and adopted its
current organizational structure in 1998. The Company is a provider of rural and
suburban cellular telephone services.
 
1997 REORGANIZATION
 
    DCC was incorporated as an Oklahoma corporation in February 1997. Under an
Agreement and Plan of Reorganization effective February 28, 1997 ("1997
Reorganization"), DCC acquired all of the outstanding Class A Common Stock,
Class C Common Stock and Class B Convertible Preferred Stock of Dobson Operating
Company ("DOC"). In exchange, the holders of the Class A Common Stock and Class
B Convertible Preferred Stock of DOC received equivalent shares of stock of DCC.
The holders of Class C Common Stock received 100,000 shares of Class A Preferred
Stock of DCC. In addition, DCC assumed all DOC outstanding stock options,
substituting shares of DCC Class B Common Stock for the DOC stock subject to
options. As a result of the 1997 Reorganization, DCC became the parent company
of DOC and the stock of certain subsidiaries of DOC was distributed to DCC.
 
1998 REORGANIZATIONS
 
    In conjunction with the January 1998 issuance of 175,000 shares of 12.25%
Senior Exchangeable Preferred Stock mandatorily redeemable in 2008 (see Note 6),
the Company formed three new subsidiaries: Dobson Cellular Operating Company
("DCOC"), DOC Cellular Subsidiary Company ("DOC Cellular Subsidiary") and Logix
Communications Enterprises, Inc. ("Logix"), formerly named Dobson Wireline
Company (collectively, the "January 1998 Reorganization"). DCOC was created as
the holding company for subsidiaries formed to effect certain cellular
acquisitions. DCOC has been designated an unrestricted subsidiary under the
Senior Note Indenture which covers the DCC Senior Notes discussed in Note 6. DOC
Cellular Subsidiary was created as the holding company for the then existing
cellular subsidiaries. Logix was created as the holding company for the
Company's incumbent local exchange carrier ("ILEC"), fiber and integrated
communications provider ("ICP") operations. Logix was designated an unrestricted
subsidiary under the Senior Note Indenture and the Certificate of Designation
establishing the Senior Exchangeable Preferred Stock.
 
    On September 30, 1998, the Company adopted a plan to spin off Logix as
discussed in Note 3 (the "September 1998 Reorganization").
 
    In conjunction with the December 1998 acquisition of Sygnet Wireless, Inc.
("Sygnet Acquisition"), the Company formed a new subsidiary, Dobson/Sygnet
Communications Company ("Dobson/Sygnet") (the "December 1998 Reorganization").
Dobson/Sygnet was created as the holding company for the subsidiaries acquired
in the Sygnet Acquisition. Collectively, the January 1998 Reorganization, the
September 1998 Reorganization and the December 1998 Reorganization are known as
the "1998 Reorganizations."
 
CAPITAL RESOURCES AND GROWTH
 
    The Company's total indebtedness and debt service requirements have
substantially increased as a result of the transactions described in Note 9 and
the Company will be subject to significant financial restrictions and
limitations. If the Company is unable to satisfy any of the covenants under the
credit facilities described in Note 6, including financial covenants, the
Company will be unable to borrow under

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. ORGANIZATION: (CONTINUED)
the credit facilities 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.
 
2. SIGNIFICANT ACCOUNTING POLICIES:
 
PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements of the Company include the accounts of
all majority owned subsidiaries. For financial reporting purposes, the Company
reports 100% of revenues and expenses for the markets for which it provides
cellular telecommunications service. However, in several of its markets, the
Company holds less than 100% of the equity ownership. The minority stockholders'
and partners' shares of income or losses in those markets are reflected in the
consolidated statements of operations as minority interests in income of
subsidiaries. For financial reporting purposes, the Company consolidates each
subsidiary and partnership in which it has a controlling interest (greater than
50%). Significant intercompany accounts and transactions have been eliminated.
Investments in unconsolidated partnerships where the Company does not have a
controlling interest are accounted for under the equity method.
 
    The Company is responsible for managing and providing administrative
services for certain partnerships of which the Company is the majority partner.
The Company is accountable to the partners and shareholders for the execution
and compliance with contracts and agreements and for filing of instruments
required by law which are made on behalf of these partnerships and corporation.
The books and records of these partnerships and corporation are also maintained
by the Company.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents on the accompanying consolidated balance sheets
includes cash and short-term investments with original maturities of three
months or less.
 
INVENTORY
 
    The Company values its inventory at the lower of cost or market on the
first-in, first-out method of accounting.
 
   
IMPAIRMENT OF LONG-LIVED ASSETS
    
 
   
    The Company assesses potential impairments of long-lived assets, certain
identifiable intangibles and goodwill 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, including
intangible assets. The amount of any recognized impairment would be based on the
estimated fair value of the asset subject to impairment compared to the carrying
amount of such asset. The fair value of intangible assets will be determined
based

on the discounted cash flows of the market or markets to which the intangible
assets relate. No such losses have been identified by the Company.
    
 
    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.
 
CELLULAR LICENSE ACQUISITION COSTS
 
    Cellular license acquisition costs consist of amounts paid to acquire FCC
licenses to provide cellular services. Cellular license acquisition costs are
being amortized on a straight-line basis over fifteen years. Amortization
expense of $1,596,794, $10,528,125 and $30,064,955 was recorded in 1996, 1997
and 1998, 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.
 
DEFERRED COSTS
 
    Deferred costs consist primarily of fees incurred to secure long-term debt.
Deferred financing costs are being amortized on a straight-line basis over the
term of the debt of eight to ten years. Amortization expense related to these
costs of $401,871, $1,074,845 and $1,965,461 was recorded in 1996, 1997 and
1998, respectively.
 
OTHER INTANGIBLES
 
    Other intangibles consist of amounts paid to acquire FCC licenses to provide
PCS service and amounts paid to acquire cellular customer lists. PCS license
acquisition costs are not being amortized until the Company's PCS service
becomes operational. Customer list acquisition costs are being amortized on a
straight-line basis over five years. Amortization expense of $0, $851,107 and
$1,219,940 was recorded in 1996, 1997 and 1998, respectively.
 
ADVERTISING COSTS
 
    Advertising costs are expensed as incurred and are included as marketing and
selling expenses in the accompanying consolidated statements of operations.
 
INCOME TAXES
 
    The Company files a consolidated income tax return. Income taxes are
allocated among the various entities included in the consolidated tax return, as
agreed, based on the ratio of each entity's taxable income (loss) to
consolidated taxable income (loss). Deferred income taxes reflect the estimated
future tax effects of differences between financial statement and tax bases of
assets and liabilities at year end.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
REVENUE RECOGNITION
 
    The Company records service revenues over the period they are earned. The
cost of providing service is recognized as incurred. Airtime and toll revenue is
billed in arrears. The Company accrued estimated unbilled revenues for services
provided of approximately $1,209,000 and $3,445,000 as of December 31, 1997 and
1998, respectively, which are included in accounts receivable in the
accompanying consolidated balance sheets. Monthly access charges are billed in
advance and are reflected as deferred revenue on the accompanying consolidated
balance sheets. Cellular equipment sales are recognized when the cellular
equipment is delivered to the customer. Subscriber acquisition costs (primarily
commissions and loss on equipment sales) are expensed as incurred.
 
EARNINGS PER SHARE
 
    In 1997, the Company adopted SFAS No. 128, "Earnings Per Share." As a
result, the Company's reported net loss per common share for 1996 was restated.
Basic loss per common share is computed by the weighted average number of shares
of common stock outstanding during the year. Diluted net loss per common share
has been omitted because the impact of stock options and convertible preferred
stock on the Company's net loss per common share is anti-dilutive.
 
USE OF ESTIMATES
 
    The preparation of these consolidated financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the consolidated
financial statements and accompanying notes. Actual results could 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
56% of the Company's cellular roaming revenue was earned from two cellular
carriers during the year ended December 31, 1996. Approximately 45% and 59% of
the Company's cellular roaming revenue was earned from three cellular carriers
during the years ended December 31, 1997 and 1998, respectively.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
    In July 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Derivatives and Hedging ("SFAS 133").
SFAS 133 establishes uniform hedge accounting criteria for all derivatives
requiring companies to formally document, designate and assess the effectiveness
of transactions that receive hedge accounting. Under SFAS 133, derivatives will
be recorded in the balance sheet as either an asset or liability measured at its
fair value, with changes in the fair value recognized as a component of
comprehensive income or in current earnings. SFAS 133 will be effective for
fiscal years beginning after June 15, 1999. Under SFAS 133, the Company would
record a liability of $5.4 million relating to its interest rate hedge valuation
at December 31, 1998. The Company has not determined the timing or method of
adoption of SFAS 133.

3. DISCONTINUED OPERATIONS
 
    The Company intends to distribute the stock of Logix to certain of the
Company's shareholders in a tax-free spin-off. The timing of the spin-off is
subject to receipt of a favorable tax ruling or favorable tax opinion acceptable
to the Company and its shareholders. The wireline segment, or Logix and its
subsidiaries, operates as an integrated communications provider under the
LOGIXSM brand name in Oklahoma and Texas, owns local telephone exchanges in
Oklahoma and operates regional fiber optic transmission networks in Oklahoma,
Texas and Colorado. Pursuant to Accounting Principles Board Opinion ("APB") No.
30, "Reporting the Results of Operations-Reporting the Effects of Disposal of a
Segment of a Business, and Extraordinary, Unusual, and Infrequently Occurring
Events and Transactions," the consolidated financial statements have been
restated for all periods presented to reflect the wireline operations, assets
and liabilities as discontinued operations. The assets and liabilities of such
operations have been classified as "Net assets (liabilities) of discontinued
operations" on the consolidated balance sheets and consist of the following:

    On March 25, 1998, the Company's subsidiary DCOC established a $200 million
senior secured credit facility (the "DCOC Credit Facility"). DCOC's obligations
under the DCOC Credit Facility are secured by all current and future assets of
DCOC. At the same time, the Company's subsidiary DOC established a $250 million
senior secured credit facility (the "DOC Credit Facility") to replace its
existing revolving credit facility established on February 28, 1997 ("1997
Credit Facility") and discussed below. The DOC Credit Facility is secured by all
of DOC's stock and the stock or partnership interests of its restricted
subsidiaries and all assets of DOC and its restricted subsidiaries. DCOC is
designated an unrestricted subsidiary with regard to the DOC Facility. The
Company and DOC's wholly owned subsidiaries other than Logix and the Arizona 5
Partnership have guaranteed DOC's obligations under the DOC Credit Facility.
Initial proceeds from the DCOC Credit Facility and DOC Credit Facility were used
primarily to refinance existing indebtedness and finance the 1998 acquisitions
described above. The Company expects to use the remaining availability under the

capital expenditures, consummate future acquisitions and fund general corporate
operations. The facilities will terminate in 2006.
 
    The Dobson/Sygnet Credit Facilities, the DCOC Credit Facility and the DOC
Credit Facility require the Company to maintain certain financial ratios. The
failure to maintain such ratios would constitute an event of default,
notwithstanding the Company's ability to meet its debt service obligations.
 
    In connection with the closing of the DOC Credit Facility, the Company
extinguished its 1997 Credit Facility and recognized a pretax loss of
approximately $3.3 million as a result of writing off previously capitalized
financing costs associated with the revolving credit facility. Such amount is
included in the Company's consolidated statement of operations, net of tax, for
the year ended December 31, 1998 as an extraordinary expense.
 
    On February 28, 1997, the Company amended and restated its existing bank
credit agreement ("1996 Credit Facility") and established the 1997 Credit
Facility. In connection with the closing of the 1997 Credit Facility, the
Company extinguished its 1996 Credit Facility and recognized a pretax loss of
approximately $2.5 million as a result of writing off previously capitalized
financing costs associated with the 1996 Credit Facility. This loss has been
reflected as an extraordinary item, net of tax, in the Company's consolidated
statement of operations for the year ended December 31, 1997.
 
    On March 19, 1996, the Company amended and restated its existing bank credit
agreement ("Old Credit Facility") and established the 1996 Credit Facility. In
connection with this amendment, the Company extinguished its Old Credit Facility
and recognized a pretax loss of approximately $.8 million as a result of writing
off previously capitalized financing costs. This loss has been reflected as an
extraordinary item, net of tax, in the accompanying consolidated statement of
operations for the year ended December 31, 1996.
 
SENIOR NOTES
 
    On December 23, 1998, the Company's subsidiary issued $200 million of 12.25%

    On February 28, 1997, the Company issued $160 million of 11.75% Senior Notes
maturing in 2007 ("DCC Senior Notes"). The net proceeds were used to finance the

INTEREST RATE HEDGES
 
    In April 1997, the Company entered into an interest rate hedge agreement
terminating on April 24, 2002 to hedge the Company's interest expense on $160
million of its indebtedness under the DOC Credit Facility. In 1998, the
counterparty exercised its rights under the swap agreement, fixing the interest
rate at 6.13% plus a factor based on the Company's leverage. The Company
accounts for this as a hedge.
 
    The Company is currently negotiating an interest rate swap agreement to
establish a fixed interest rate on $75 million of its indebtedness under the
Dobson/Sygnet Credit Facilities.
 
7. RESTRICTED CASH AND INVESTMENTS:
 
    Restricted cash and investments consist of interest pledge deposits for the
Dobson/Sygnet Senior Notes and the DCC Senior Notes. The Dobson/Sygnet Senior
Notes interest pledge deposit includes the initial deposit of $67.7 million (as
discussed in Note 6), plus interest earned. The DCC Senior Notes interest pledge
deposit of approximately $9.3 million includes an initial deposit of $38.4
million (as discussed in Note 6), net of interest earned and payments issued to
bondholders. Amortization expense of $322,850 and $269,101 was recorded in 1997
and 1998, respectively, for bond premiums recorded with the purchase of the
restricted investments. At December 31, 1998, the carrying value of these
investments exceeded the market value by approximately $326,000.

of the Class C common stock received 100,000 shares of Class A preferred stock
of Dobson Holdings. In addition, Dobson Holdings assumed all DCC outstanding
stock options, substituting shares of Dobson Holdings Class B common stock for
the stock subject to options. As a result, Dobson Holdings is the parent company
of DCC.
 
    As part of the reorganization, the stock of certain subsidiaries was
distributed to Dobson Holdings so that DCC is the holding company for the
wireline and cellular subsidiaries. Additionally, DCC changed its corporate name
to DOC and Dobson Holdings changed its corporate name to DCC.
 
    On March 19, 1996, the Company redeemed all of the shares of the Class A
Preferred for $5,913,000, which is reflected in the accompanying consolidated
statement of cash flows for the year ended December 31, 1996.
 
    In conjunction with the execution of the amended and restated revolving
credit facility on March 19, 1996, as described in Note 6, the Company canceled
its then outstanding Class A and Class B common stock and authorized the capital
structure of the Company to consist of 1,000,000 shares of Class A voting common
stock, $1 par value per share, 31,000 shares of Class B common stock, $1 par
value per share, 59,130 shares of 10% cumulative, compounded, convertible,
redeemable Class A preferred stock, $100 par value per share, and 100,000 shares
of Class B convertible preferred stock ("Class B Preferred"), $1 par value per
share, 8% dividend that accrues on a daily basis. On the same date, the Company
issued 100,000 shares of Class B Preferred. The net proceeds from the issuance
of the Class B Preferred was approximately $9,400,000. In addition, the Company
issued 473,152 shares of Class A voting common stock to the holders of the
original Class A common stock. On November 15, 1996, the Company amended its
certificate of incorporation to eliminate Class A Preferred from its authorized
capital stock.
 
    Holders of Class B Preferred are entitled to cumulative dividends as and
when declared by the board of directors of the Company and a liquidation
preference over the other classes of capital stock. The Class B Preferred
stockholders are also entitled to a dividend equal to the amount they would have
received had the Preferred Stock been converted into Class A common stock. Each
share of Class B Preferred is convertible into Class A common stock initially at
a ratio of one to one. Each share of Class B Preferred has voting rights
equivalent to Class A common stock, at a rate equal to the number of Class A
common shares into which the share of Class B Preferred is convertible at the
record date of such vote. In addition, the Class B Preferred stockholders have
the right, as a class, to elect two members of the board of directors of the
Company.
 
    In February 1997, a $7.5 million dividend was paid on the Class A Common
Stock. As a result of the $7.5 million dividend, holders of Class B Preferred
were entitled to a "Make-Whole Dividend" of approximately $1.6 million. In lieu
of such Make-Whole Dividend, the holders of Class B Preferred received 100,000
shares of Class C Preferred Stock having a liquidation preference of $1,623,329.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Horizon, G.P., Inc.
 
    We have audited the accompanying combined statements of assets and
liabilities of The Cellular Telephone Business of Selected Systems of Horizon
Cellular Telephone Company, L.P. as of December 31, 1995 and 1996, and the
related combined statements of operations and net assets and of cash flows for
each of the three years in the period ended December 31, 1996. These financial
statements are the responsibility of Horizon Cellular Telephone Company, L.P.'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 assets and liabilities of The Cellular Telephone
Business of Selected Systems of Horizon Cellular Telephone Company, L.P. at

             THE CELLULAR TELEPHONE BUSINESS OF SELECTED SYSTEMS OF
                    HORIZON CELLULAR TELEPHONE COMPANY, L.P.
 
                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1996
 
1. BASIS OF PRESENTATION AND DESCRIPTION OF BUSINESS
 
    The accompanying audited combined financial statements of The Cellular
Telephone Business of Selected Systems of Horizon Cellular Telephone Company,
L.P. (HCTC) reflect the combined assets and liabilities, combined results of
operations, and combined cash flows of the cellular telephone business of
Horizon Cellular Telephone Company of Frederick ("Frederick"), Horizon Cellular
Telephone Company of Bedford ("Bedford"), Horizon Cellular Telephone Company of
Hagerstown, L.P. ("Hagerstown"), and the Cumberland Cellular Partnership
("Cumberland") (collectively referred to as "the Selected Systems," "the
Systems," or "the Company") as of December 31, 1995 and 1996, and for each of
the three years in the period ended December 31, 1996. The accompanying
financial statements are presented on HCTC's historical cost basis and are
intended to reflect only the assets, liabilities, operations, and cash flows
relating to the cellular telephone business of the named legal entities, which
are majority-owned subsidiary partnerships of HCTC, and do not represent the
financial statements of the named legal entities. The combined financial
statements include only the operating results since the Systems were acquired by
HCTC.
 
    The Company owns, designs, develops, and operates cellular communications
systems. With the exception of Cumberland, KCCGP, L.P. (KCCGP) is the managing
and sole general partner of the subsidiary partnerships that own directly the
aforesaid cellular telephone businesses at December 31, 1996. With respect to
Cumberland, KCCGP is the managing and sole general partner of Horizon Cellular
Telephone Company of Cumberland, L.P., a 90.55% general partner in Cumberland.
KCCGP performs certain administrative functions for the Systems and,
accordingly, certain expenses of KCCGP (see Note 5) have been allocated to the
Systems on a basis which, in the opinion of management, is reasonable. However,
such expenditures are not necessarily indicative of, and it is not practicable
for management to estimate, the nature and level of expenses which might have
been incurred had the Systems been operating as separate independent companies.
 
2. ACQUISITIONS
 
    In April 1994, HCTC simultaneously closed on various purchase, sale and
exchange agreements which ultimately resulted in HCTC (i) acquiring a majority
interest (90.55%) in the non-wireline FCC Operating License of the Cumberland
MSA, (ii) acquiring the non-wireline FCC Operating License of the Hagerstown MSA
together with certain operating assets, in exchange for substantially all of the
assets of the eastern portion of Bedford, and (iii) making a net payment of $4.2
million in cash. Simultaneously, HCTC contributed the Operating License to
Cumberland and contributed the Operating License to Hagerstown in exchange for a
99.0% interest in Hagerstown and KCCGP obtained a 1.0% interest in Hagerstown.
 
    Effective January 1, 1995, the operations of Frederick and Bedford were
merged into Hagerstown. As part of the market consolidation, the general partner
interests were reorganized. KCCGP acquired an additional .9% interest in
Frederick (resulting in a 1% general partner ownership), reducing HCTC's Limited
Partnership interest to 99%. The additional partner contribution was based on
the estimated fair market value of the Frederick System.
 
    All of the Company's acquisitions were accounted for under the purchase
method of accounting; accordingly, assets acquired and liabilities assumed have
been recorded at their estimated fair market values at the dates of acquisition
and their results of operations are included in the accompanying combined
statements of operations since the date of acquisition. The accompanying
financial statements

exclude the results of operations of the eastern portion of Bedford. The excess
of purchase price over the fair market value of identifiable net tangible assets
acquired has been allocated to customer lists and licenses. Pro forma results of
operations for 1994, assuming the acquisitions of Hagerstown and Cumberland
occurred on January 1, 1994, would not differ materially from reported results.
 
3. ACCOUNTING POLICIES
 
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 and
accompanying notes. Actual results could differ from those estimates.
 
INVENTORIES
 
    Inventories are carried at the lower of cost (using the first-in, first-out
method) or market.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost and are depreciated over their
estimated useful lives (three to twelve years) using the straight-line method.
 
    Depreciation expense amounted to approximately $1,143,000 in 1994,
$1,237,000 in 1995, and $1,405,000 in 1996.
 
LICENSES
 
    Licenses primarily represent the acquisition costs of the Operating
Licenses. Such costs are being amortized over a period of 40 years using the
straight-line method.
 
    The Systems periodically review the carrying value of their licenses to
determine whether such amounts are recoverable based on undiscounted future cash
flows and whether a reduction to fair value is necessary. There have been no
such reductions through December 31, 1996.
 
ADVANCES FROM AFFILIATES
 
    Advances from affiliates primarily represent cash advances from HCTC and
KCCGP which provided funds for investing and operating activities, and have no
specific repayment terms. Interest expense is charged monthly at a rate of
11 3/8% of the ending balances payable to HCTC.
 
REVENUE AND EXPENSE RECOGNITION
 
    Cellular airtime revenue and access charges are recognized as service is
provided. Cellular airtime is billed in arrears and access charges are billed in
advance. Subscriber acquisition costs (mainly commissions and loss on equipment
sales) are expensed when incurred. Accounts receivable consist mainly of amounts
due from subscribers and other cellular companies whose subscribers use the
Systems' cellular service.

3. ACCOUNTING POLICIES (CONTINUED)
    Approximately 40% of the 1996 roaming revenues were generated from
subscribers of a cellular company serving an adjacent market when such
subscribers place or receive calls on the Company's system.
 
ADVERTISING EXPENSES
 
    Advertising expenses are charged to operations as incurred and amounted to
approximately $256,100 in 1994, $394,400 in 1995, and $512,000 in 1996.
 
ACCRUED EXPENSES
 
    Accrued expenses consist of the following at December 31:

INCOME TAXES
 
    The legal entities under which the Systems operate are partnerships
organized under the laws of Delaware. Accordingly, federal and state income
taxes are not paid at the partnership level but by the ultimate partners. The
tax basis of the Systems' assets amounted to approximately $28.8 million and $30
million at December 31, 1995 and 1996, respectively.
 
NEW ACCOUNTING STANDARDS
 
    In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to be Disposed of," which
requires impairment losses to be recorded on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. The impact of adopting this Statement in 1996 was not material
to the financial statements.
 
    SFAS No. 123, "Accounting for Stock-Based Compensation," is effective for
fiscal years beginning after December 15, 1995. SFAS 123 provides companies with
a choice to follow the provisions of SFAS 123 in determining stock-based
compensation expense or to continue with the provisions of APB 25, "Accounting
for Stock Issued to Employees." Although the Selected Systems expect to continue
to follow APB 25, Statement 123 would have no effect on the combined financial
statements for the periods indicated (see Note 6).

4. COMMITMENTS AND CONTINGENCIES
 
    The Systems lease office space, office equipment, and cellular sites and
facilities under operating leases with initial terms ranging from 1 to 20 years.
Most cellular sites contain renewal options ranging up to 25 years.
 
    Future minimum payments under noncancelable operating leases with initial
terms of one year or more consisted of the following amounts as of December 31,
1996:

    Rental expense amounted to approximately $251,100 in 1994, $336,500 in 1995,
and $389,800 in 1996.
 
5. RELATED PARTY TRANSACTIONS
 
    KCCGP provides various administrative services to the Systems, including
accounting, engineering, and marketing and advertising services, in addition to
funding working capital requirements and capital expenditures as necessary.
These expenses are charged, first on the basis of direct usage when
identifiable, with the remainder allocated equally among its operating systems.
Allocated expenses amounted to $107,000 for the year ended December 31, 1994,
and $50,000 for each of the years ended December 31, 1995 and 1996.
 
6. BENEFIT PLANS
 
    HCTC has granted certain officers of the Selected Systems limited
partnership appreciation rights in HCTC pursuant to a Limited Partnership Unit
Appreciation Rights Plan ("LPAR Plan"), as amended, that was adopted September
1, 1994 to be effective January 1, 1993. Upon the occurrence of certain events
as specified therein ("Termination Events"), participants are entitled to share
in the amounts, if any, of distributions to HCTC's partners after all capital
contributions made by HCTC's partners have been repaid, together with a fixed
return on such contributions. Such rights vest over a period of five years;
however, vesting is automatically accelerated upon the occurrence of a
Termination Event. LPAR Plan compensation expense of $275,000 has been
recognized and included in accrued expenses as of December 31, 1996, which is
the LPAR Plan amount attributable to participants who are employees of the
Selected Systems.
 
    Effective July 1, 1994, KCCGP established an employee savings plan (the
"Plan") that qualifies as a deferred salary arrangement under Section 401(k) of
the Internal Revenue Code. Under the Plan, which covers employees of the
Selected Systems who have met certain eligibility requirements, participating
employees may defer up to 15% of their pretax earnings, up to the Internal
Revenue Service annual

contribution limit ($9,500 for calendar year 1996). The Company matches up to
50% of the employee's contributions, up to a maximum of 3% of the employee's
earnings. Employees who participate in the LPAR Plan are excluded from matching
contributions. Matching Plan contributions, which vest equally over five years,
amounted to approximately $7,600 in 1994, $10,100 in 1995, and $17,600 in 1996.
 
7. SUBSEQUENT EVENTS
 
    On November 19, 1996, the Company entered into a definitive agreement to
sell the FCC Operating Licenses of the Selected Systems, together with certain
operating assets and liabilities, to Dobson Cellular of Maryland, Inc. for
approximately $75 million, subject to adjustment. The combined financial
statements do not reflect either the estimated gain, or any expenses incurred or
expected to be incurred related to the sale of the systems. The sale is expected
to close in February of 1997, and is subject to certain regulatory and other
approvals.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Partners of
 
Gila River Cellular General Partnership:
 
    We have audited the accompanying balance sheets of Gila River Cellular
General Partnership (an Arizona general partnership) as of December 31, 1996 and
1995, and the related statements of operations, changes in partners' capital and
cash flows for each of the three years in the period ended December 31, 1996.
These financial statements are the responsibility of the Partnership'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 financial position of Gila River Cellular General
Partnership as of December 31, 1996 and 1995, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1996, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                        DECEMBER 31, 1994, 1995 AND 1996
 
1. ORGANIZATION
 
    Gila River Cellular General Partnership (an Arizona general partnership) was
formed on September 1, 1990, to fund, establish and provide cellular
telecommunication services to customers within the geographical area between the
cities of Phoenix and Tucson, Arizona known as the Gila Rural Service Area
("RSA") Number 5 (corridor). Gila River Telecommunications, Inc., Tohono O'odham
Utility Authority (a subsidiary organization of the Tohono O'odham Nation), and
Aztel, Inc. participate as general partners. U S WEST NewVector Group, Inc.
participates as the managing general partner.
 
    Effective December 31, 1994, the partners of Gila River Cellular General
Partnership entered into a definitive agreement to amend the Partnership
Agreement to incorporate the geographical service area of Arizona RSA Number 5
(non-corridor) served by a separate partnership of Gila River
Telecommunications, Inc., Tohono O'odham Utility Authority and Aztel, Inc. As a
result of this transaction, the ownership interest of the general partners of
Gila River Cellular General Partnership has been revised as reflected in the
accompanying financial statements.
 
    In late 1996, Dobson Communications Corporation ("Dobson") and the general
partners signed a letter of intent wherein Dobson agreed to purchase the
interests of the general partners. Upon completion of the transaction, which is
expected to occur in the first half of 1997, Dobson and the Gila River Indian
Community will have a 100% interest in Arizona RSA Number 5. At Dobson's option,
during the sales transition and post-transition periods, Dobson may purchase
services from the managing general partner similar to those discussed in Note 4.
 
2. SIGNIFICANT ACCOUNTING POLICIES:
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents include amounts which are readily convertible into
cash and which are not subject to significant risk from fluctuations in interest
rates.
 
INVENTORIES
 
    Inventories are stated at the lower of cost or market on a first-in,
first-out (FIFO) basis. Inventories consist of cellular mobile telephone
equipment that is purchased by the Partnership primarily for sale to customers.
 
PROPERTY, EQUIPMENT AND DEPRECIATION
 
    The Partnership's investment in property and equipment is stated at cost
less accumulated depreciation. Interest incurred during construction is
capitalized and amortized over the life of the underlying asset. Interest of
$2,404, $163,427 and $9,216 was capitalized during the year ended December 31,
1994, 1995 and 1996, respectively. The cost of these assets includes purchased
materials, contracted services, internal labor and applicable overhead.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    Depreciation is calculated on a straight-line basis over the following
estimated economic life of the assets:
 
<TABLE>
<S>                                             <C>
                                                     3 to 20
Cellular systems..............................         years
Furniture and equipment.......................  3 to 5 years
</TABLE>
 
INCOME TAXES
 
    Under provisions of the Internal Revenue Code, the partners include their
respective share of Partnership income or loss in their individual tax returns.
Accordingly, no provision for income taxes has been made in the accompanying
financial statements.
 
MANAGING GENERAL PARTNER FINANCING
 
    The managing general partner advances funds to the Partnership as necessary
to finance operations and network construction. Interest is charged to the
Partnership on these advances at a rate equivalent with U S WEST NewVector
Group, Inc.'s borrowing rate which averaged 7.5% for the years ended December
31, 1994 and 1995 and 8.1% for the year ended December 31, 1996, respectively.
Interest expense incurred and paid, net of amounts capitalized for the years
ended December 31, 1994, 1995 and 1996 was $0, $50,024 $50,098, respectively.
 
REVENUES
 
    The Partnership earns cellular service revenue by providing access to the
cellular network (access revenue) and for use of the network (airtime revenue).
Access revenue is billed one month in advance. Airtime and access revenues are
recognized when the service is provided.
 
ADVERTISING COSTS
 
    Costs incurred for advertising are expensed as incurred.
 
ACCOUNTING ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
RECLASSIFICATION
 
    Certain reclassifications have been made to the prior year's financial
statements in order to present them on a basis consistent with that of the
current year.

5. UPGRADE OF CELLULAR SYSTEM
 
    During 1993, the Partnership decided to replace substantially all of its
cellular network equipment consisting primarily of cell site electronics. The
Partnership recorded a reserve of $460,000 in connection with this transaction
in order to reduce the cellular equipment to its net realizable value. During
the fourth quarter of 1995, assets with a book value of $1,132,394 and
accumulated depreciation of $200,153 were replaced in connection with the
upgrade. As part of this transaction, the Partnership's displaced cellular
equipment was transferred to the managing general partner at its fair market
value of $525,000.

                           DECEMBER 31, 1996 AND 1997
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    DESCRIPTION OF BUSINESS
 
    The Partnership is the owner of a license issued by the Federal
Communications Commission (FCC) to provide non-wireline cellular
telecommunications service to the California 4 Rural Service Area. California 4
Rural Service Area includes Merced, Madera and San Benito counties in central
California. The Partnership has a large customer base within this area that
includes individuals, businesses and governments. The Partnership is not
dependent on any single or major group of customers for its sales. Approximately
54% of Partnership revenue is derived from providing cellular service to
customers of other cellular companies 'roaming' through the Company's service
area. Approximately 43% of revenue is derived from providing cellular service to
its own subscriber customers. As more fully described in Note 9 to the financial
statements, in late 1997 the partner which owns the controlling interest in the
Partnership and Dobson Cellular of California, Inc. (Dobson) signed an agreement
in which the Partner agreed to sell their interest in the Partnership and to
transfer the FCC license of the Partnership to Dobson.
 
    PERVASIVENESS OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
    CASH AND CASH EQUIVALENTS
 
    Cash equivalents consist of highly liquid unrestricted cash instruments with
original maturities of three months or less. The Partnership places its
temporary cash investments with high credit quality financial institutions. At
times such investments may be in excess of the FDIC insurance limit. The
Partnership has not experienced any losses in such accounts.
 
    REVENUE RECOGNITION
 
    Cellular air time is recorded as revenue as earned. Subscriber acquisition
costs (mainly commissions and loss on equipment sales) are expensed when
incurred. Sales of equipment are recorded at the point of sale. Cellular access
charges generally are billed in advance and recognized as revenue when the
services are provided.
 
    INVENTORIES
 
    Inventories are valued at the lower of cost or market. Cost is determined
under the specific identification method.

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    PROPERTY, PLANT AND EQUIPMENT
 
    Property, plant and equipment are stated at cost. Depreciation is computed
using the straight-line method over the following estimated useful lives of the
assets:
 
<TABLE>
<S>                                                               <C>
                                                                       15-20
Buildings and towers............................................       years
Cellular and switching equipment................................    10 years
Autos and trucks................................................     5 years
Furniture, fixtures and office equipment........................   5-7 years
Leasehold Improvements..........................................     5 years
</TABLE>
 
    Expenditures for repairs and maintenance are charged to operating expense as
incurred. Betterments, replacement equipment and additions are capitalized.
 
    CONSTRUCTION IN PROGRESS
 
    The Partnership's cellular communications system expenditures are recorded
as construction in progress until the system or assets are placed in service.
When the assets are placed in service, they are transferred to the appropriate
property and equipment category and depreciated. All direct, administrative and
interest costs related to the construction are capitalized to construction in
progress during the construction period.
 
    START UP COSTS
 
    Start up costs are administrative costs incurred related to the construction
of the cellular mobile communications system. Such amounts are being amortized
over five years beginning June 1, 1992. Accumulated amortization of start up
costs at December 31, 1996 and 1997 was $625,105 and $681,933, respectively. At
December 31, 1997 the start up costs were fully amortized.
 
    LOAN COSTS
 
    Costs associated with the financing of the Partnership's debt have been
capitalized and are amortized on a straight line basis over the life of the
note. Additional costs incurred with the loan in June 1997 have been capitalized
and amortized over the remaining life of the loan. Accumulated amortization of
loan costs at December 31, 1996 and 1997 was $114,387 and $173,103,
respectively.
 
    LICENSING COSTS
 
    Licensing costs primarily represent costs incurred to acquire the Federal
Communications Commission License. Amortization of these costs began in May,
1992, using the straight-line method over a period of 40 years. In March 1997,
the Partnership entered into an agreement to use licensed software to process
billing information for its cellular communications system. In consideration of
this agreement, the Partnership paid a one-time license fee which is being
amortized using the straight-line method over a three-year period. Accumulated
amortization of licensing costs at December 31, 1997 and 1996 was $15,213 and
$3,367, respectively.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                           DECEMBER 31, 1996 AND 1997
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    INCOME TAXES
 
    The Partnership's legal form of organization is that of a partnership. A
partnership as such is not taxed under the Internal Revenue Code, rather the
income or loss of the partnership is required to be reported by each respective
partner on their appropriate tax return.
 
    ADVERTISING EXPENSES
 
    Advertising costs are expensed as incurred and amounted to approximately
$122,808 in 1996 and $183,690 in 1997. The expenses are included as marketing
and selling expenses in the statement of income.
 
    CONCENTRATIONS OF CREDIT RISK
 
    Financial instruments which potentially expose the Partnership to
concentrations of credit risk, as defined by FASB Statement No. 105 consist
primarily of trade accounts receivable and cash equivalents.
 
    At December 31, 1997 approximately 54% of trade accounts receivable were
attributable to cellular companies which subscribe to the clearinghouse network.
Of this amount, approximately 72% of these receivables were from AT&T Wireless
Services of California, Inc. (AWS-CA) companies and approximately 19% of these
receivables were from Bay Area Cellular Telephone Company, of which the parent
company of AWS-CA owns an interest. Concentrations of credit risk from these
receivables is limited due to the large number of subscribers, none of which
individually comprise a significant amount of the accounts receivable balance at
December 31, 1997. The Partnership establishes an allowance for doubtful
accounts based upon factors surrounding the credit risk of specific customers,
historical trends and other information. Receivables are not collateralized. The
Partnership is directly affected by the well being of the California economic
climate and the effects of any changes in the cellular telecommunications act.
However, management does not believe significant credit risk exists at December
31, 1997.
 
    RECLASSIFICATIONS
 
    Certain accounts relating to the prior year have been reclassified to
conform to the current year presentation. The reclassifications have no effect
on previously reported net earnings.
 
NOTE 2--SUPPLEMENTAL DISCLOSURES OF CASH FLOW INFORMATION

increases to construction in progress and notes payable-related party of
$1,253,381.

</TABLE>
 
    On December 31, 1996, the Partnership entered into an agreement which allows
the Partnership to request AT&T Wireless Services, Inc. (AWS) to place orders
for certain equipment, software, materials and services (hereinafter equipment)
intended to be used by the Partnership in the ordinary course of business for
the operation, modification, improvement or expansion of its system. Although it
is under no obligation to do so, if AWS chooses to honor in its sole discretion
any such request from the Partnership, such orders for equipment will be charged
on AWS' account and the dollar amount of such charges shall be deemed for all
purposes as loans or advances from AWS to the Partnership. The unpaid balance of
all loans or advances shall not exceed $750,000. The payment of the loans and
advances is secured by the equipment purchased and all of the Partnership's
outcollect revenues, as they are commonly defined in the cellular telephone
industry. The purchasing agreement contains a provision which allows AWS to
offset roaming revenues owed to the Partnership against amounts owed under this
purchasing agreement if the Partnership defaults in its obligation. Interest is
payable at one and one-half percent per month on the outstanding balance after
specified time intervals have elapsed. No interest cost was incurred on this
loan during 1997.

NOTE 3--NOTES PAYABLE (CONTINUED)
    On October 14, 1994, the Partnership arranged financing with a financial
institution for a $10,000,000 term loan and a $2,500,000 revolving credit loan.
On September 29, 1996, the Partnership increased the commitment on the revolving
credit loan to $4,500,000. The increased financing was obtained to satisfy a
portion of the termination fee due on the settlement of the management agreement
with RCM. On June 11, 1997, the term loan and the revolving credit loan were
combined and the total commitment on the loan was increased to $16,000,000. The
increased financing was obtained to upgrade equipment and increase the capacity
of the cellular communications system. The credit agreement associated with the
loan contains, among other covenants, provisions which limit capital
expenditures. For the year ended December 31, 1997, capital expenditures cannot
exceed $7,100,000. As of December 31, 1997, the Partnership was not in
compliance with the capital expenditures covenant. This noncompliance would, by
the terms of the loan agreement, constitute an event of default. The agreement
provides that in an event of default the bank may by notice in writing declare
all amounts owing with respect to these agreements immediately due and payable.
Due to the pending sale as discussed in Note 9, management does not expect to
receive such notice. The credit agreement also contains provisions which limit
distributions to partners to no more than $500,000 during any fiscal quarter
except distributions to the partners to pay Federal and State income taxes on
the taxable income allocated by the Borrowers to its partners. Distributions
totaling $3,219,566 and $4,769,775 were made in 1997 and 1996, respectively.
 
    At December 31, 1997, these borrowings bear interest at 2.25% above the
LIBOR rate established for the period. Total interest incurred during the years
ended December 31, 1997 and 1996 was $933,766 and $784,477, respectively. Of
this, $117,216 was capitalized in 1997 as construction costs. No interest
capitalization was required during 1996.
 
    Annual maturities of noncurrent notes payable are as follows:

NOTE 5--OBLIGATION FOR EQUIPMENT
 
    In 1995, the Partnership negotiated a contract with Ericsson Inc. for an
upgrade to the switch. The contract price for this upgrade totaled $1,782,525.
The upgrade was completed and became fully operational in January 1996. By the
terms of the contract, payment of $284,909 was made during 1995 leaving a
balance due Ericsson, Inc. of $1,497,616. The original contract for the
equipment has been adjusted to include sales tax of $123,553 for a total balance
due to Ericsson, Inc. of $1,621,169. This obligation will become due in full if
one of the following conditions are met: when the system reaches 25,000
subscribers; or if the switch is moved from its present location; or if the
switch is taken out of service; or prior to or as an item of closing of the sale
of the system to another business entity. Due to the pending sale of the system
as discussed in Note 9, management expects the obligation for the upgrade to the
switch to become due in full during 1998, therefore this obligation is
classified as a current liability at December 31, 1997 on the balance sheet.

    The Partnership had a management agreement with Rural Cellular Management
(RCM) which terminated on September 1, 1995. Prior to termination, the monthly
management fee was based upon the most current population of the Rural Service
Area (RSA) multiplied by $.1042. In 1996, the Partnership paid $45,350 to RCM
which represented a correction in the calculation of the prior year's management
fee paid. On August 24, 1996, the Partnership and RCM agreed upon a termination
fee of $4,000,000 in settlement of the management agreement. As of December 31,
1996, the partnership had paid $2,500,000 to RCM. The balance of the termination
fee, $1,500,000, was paid during the year ended December 31, 1997.

                         NOTES TO FINANCIAL STATEMENTS
 
                   DECEMBER 31, 1997, MARCH 31, 1997 AND 1998
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    DESCRIPTION OF BUSINESS
 
    The Partnership is the owner of a license issued by the Federal
Communications Commission (FCC) to provide non-wireline cellular
telecommunications service to the California 4 Rural Service Area. California 4
Rural Service Area includes Merced, Madera and San Benito counties in central
California. The Partnership has a large customer base within this area that
includes individuals, businesses and governments. The Partnership is not
dependent on any single or major group of customers for its sales. Approximately
54% of Partnership revenue is derived from providing cellular service to
customers of other cellular companies 'roaming' through the Company's service
area. Approximately 43% of revenue is derived from providing cellular service to
its own subscriber customers. As more fully described in Note 9 to the financial
statements, in late 1997 the partner which owns the controlling interest in the
Partnership and Dobson Cellular of California, Inc. (Dobson) signed an agreement
in which the Partner agreed to sell their interest in the Partnership and to
transfer the FCC license of the Partnership to Dobson.
 
    PERVASIVENESS OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
    CASH AND CASH EQUIVALENTS
 
    Cash equivalents consist of highly liquid unrestricted cash instruments with
original maturities of three months or less. The Partnership places its
temporary cash investments with high credit quality financial institutions. At
times such investments may be in excess of the FDIC insurance limit. The
Partnership has not experienced any losses in such accounts.
 
    REVENUE RECOGNITION
 
    Cellular air time is recorded as revenue as earned. Subscriber acquisition
costs (mainly commissions and loss on equipment sales) are expensed when
incurred. Sales of equipment are recorded at the point of sale. Cellular access
charges generally are billed in advance and recognized as revenue when the
services are provided.
 
    INVENTORIES
 
    Inventories are valued at the lower of cost or market. Cost is determined
under the specific identification method.

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    PROPERTY, PLANT AND EQUIPMENT
 
    Property, plant and equipment are stated at cost. Depreciation is computed
using the straight-line method over the following estimated useful lives of the
assets:

                                                                       15-20
Buildings and towers............................................       years
Cellular and switching equipment................................    10 years
Autos and trucks................................................     5 years
Furniture, fixtures and office equipment........................   5-7 years
Leasehold Improvements..........................................     5 years
</TABLE>
 
    Expenditures for repairs and maintenance are charged to operating expense as
incurred. Betterments, replacement equipment and additions are capitalized.
 
    CONSTRUCTION IN PROGRESS
 
    The Partnership's cellular communications system expenditures are recorded
as construction in progress until the system or assets are placed in service.
When the assets are placed in service, they are transferred to the appropriate
property and equipment category and depreciated. All direct, administrative and
interest costs related to the construction are capitalized to construction in
progress during the construction period.
 
    START UP COSTS
 
    Start up costs are administrative costs incurred related to the construction
of the cellular mobile communications system. Such amounts are being amortized
over five years beginning June 1, 1992. Accumulated amortization of start up
costs at December 31, 1997 and March 31, 1998 was $681,933 and $681,933,
respectively. At December 31, 1997 the start up costs were fully amortized.
 
    LOAN COSTS
 
    Costs associated with the financing of the Partnership's debt have been
capitalized and are amortized on a straight line basis over the life of the
note. Additional costs incurred with the loan in June 1997 have been capitalized
and amortized over the remaining life of the loan. Accumulated amortization of
loan costs at December 31, 1997 and March 31, 1998 was $173,103 and $188,907,
respectively.
 
    LICENSING COSTS
 
    Licensing costs primarily represent costs incurred to acquire the Federal
Communications Commission License. Amortization of these costs began in May,
1992, using the straight-line method over a period of 40 years. In March, 1997,
the Partnership entered into an agreement to use licensed software to process
billing information for its cellular communications system. In consideration of
this agreement, the Partnership paid a one-time license fee which is being
amortized using the straight-line method over a three-year period. Accumulated
amortization of licensing costs at December 31, 1997 and March 31, 1998 was
$15,213 and $18,730, respectively.

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    INCOME TAXES
 
    The Partnership's legal form of organization is that of a partnership. A
partnership as such is not taxed under the Internal Revenue Code, rather the
income or loss of the partnership is required to be reported by each respective
partner on their appropriate tax return.
 
    ADVERTISING EXPENSES
 
    Advertising costs are expensed as incurred and amounted to approximately
$42,535 and $85,778 for the three months ended March 31, 1997 and 1998,
respectively. The expenses are included as marketing and selling expenses in the
statement of income.
 
    CONCENTRATIONS OF CREDIT RISK
 
    Financial instruments which potentially expose the Partnership to
concentrations of credit risk, as defined by FASB Statement No. 105 consist
primarily of trade accounts receivable and cash equivalents.
 
    At March 31, 1998, approximately 48% of trade accounts receivable were
attributable to cellular companies which subscribe to the clearinghouse network.
Of this amount, approximately 72% of these receivables were from AT&T Wireless
Services of California, Inc. (AWS-CA) companies and approximately 19% of these
receivables were from Bay Area Cellular Telephone Company, of which the parent
company of AWS-CA owns an interest. Concentrations of credit risk from these
receivables is limited due to the large number of subscribers, none of which
individually comprise a significant amount of the accounts receivable balance at
March 31, 1998. The Partnership establishes an allowance for doubtful accounts
based upon factors surrounding the credit risk of specific customers, historical
trends and other information. Receivables are not collateralized. The
Partnership is directly affected by the well being of the California economic
climate and the effects of any changes in the cellular telecommunications act.
However, management does not believe significant credit risk exists at March 31,
1998.
 
    RECLASSIFICATIONS
 
    Certain accounts relating to the prior year have been reclassified to
conform to the current year presentation. The reclassifications have no effect
on previously reported net earnings.

    On December 31, 1996, the Partnership entered into an agreement which allows
the Partnership to request AT&T Wireless Services, Inc. (AWS) to place orders
for certain equipment, software, materials and services (hereinafter equipment)
intended to be used by the Partnership in the ordinary course of business for
the operation, modification, improvement or expansion of its system. Although it
is under no obligation to do so, if AWS chooses to honor in its sole discretion
any such request from the Partnership, such orders for equipment will be charged
on AWS' account and the dollar amount of such charges shall be deemed for all
purposes as loans or advances from AWS to the Partnership. The unpaid balance of
all loans or advances shall not exceed $750,000. The payment of the loans and
advances is secured by the equipment purchased and all of the Partnership's
outcollect revenues, as they are commonly defined in the cellular telephone
industry. The purchasing agreement contains a provision which allows AWS to
offset roaming revenues owed to the Partnership against amounts owed under this
purchasing agreement if the Partnership defaults in its obligation. Interest is
payable at one and one-half percent per month on the outstanding balance after
specified time intervals have elapsed. No interest cost was incurred on this
loan during 1998.
 
    On October 14, 1994, the Partnership arranged financing with a financial
institution for a $10,000,000 term loan and a $2,500,000 revolving credit loan.
On September 29, 1996, the Partnership increased the commitment on the revolving
credit loan to $4,500,000. The increased financing was obtained to satisfy a
portion of the termination fee due on the settlement of the management agreement
with RCM. On June 11, 1997, the term loan and the revolving credit loan were
combined and the total commitment on the loan was increased to $16,000,000. The
increased financing was obtained to upgrade equipment and increase the capacity
of the cellular communications system. The credit agreement associated with the
loan contains, among other covenants, provisions which limit capital
expenditures. For the year ended December 31, 1997, capital expenditures cannot
exceed $7,100,000. As of December 31, 1997, the Partnership was not in
compliance with the capital expenditures covenant. This noncompliance would, by
the terms of the loan agreement, constitute an event of default. The agreement
provides that in an event of default the bank may by notice in writing declare
all amounts owing with respect to these agreements immediately due and payable.
Due to the pending sale as discussed in Note 9, management does not expect to
receive such

notice. The credit agreement also contains provisions which limit distributions
to partners to no more than $500,000 during any fiscal quarter except
distributions to the partners to pay Federal and State income taxes on the
taxable income allocated by the Borrowers to its partners. Distributions
totaling $3,219,566 and $1,000,000 were made during the period ended December
31, 1997 and March 31, 1998, respectively.
 
    At March 31, 1998, these borrowings bear interest at 2.25% above the LIBOR
rate established for the period. Total interest incurred during the three month
period ended March 31, 1997 and 1998 was $204,367 and $168,442, respectively. Of
this, $30,316 and $24,238 were capitalized in 1997 and 1998, respectively, as
construction costs.

NOTE 5--OBLIGATION FOR EQUIPMENT
 
    In 1995, the Partnership negotiated a contract with Ericsson, Inc. for an
upgrade to the switch. The contract price for this upgrade totaled $1,782,525.
The upgrade was completed and became fully operational in January, 1996. By the
terms of the contract, payment of $284,909 was made during 1995 leaving a

balance due Ericsson, Inc. of $1,497,616. The original contract for the
equipment has been adjusted to include sales tax of $123,553 for a total balance
due to Ericsson, Inc. of $1,621,169. This obligation will become due in full if
one of the following conditions are met: when the system reaches 25,000
subscribers; or if the switch is moved from its present location; or if the
switch is taken out of service; or prior to or as an item of closing of the sale
of the system to another business entity. Due to the subsequent sale of the
system as discussed in Note 9, management fulfilled the obligation for the
upgrade to the switch in April, 1998, therefore this obligation is classified as
a current liability at March 31, 1998 on the balance sheet.

    The Partnership had a management agreement with Rural Cellular Management
(RCM) which terminated on September 1, 1995. Prior to termination, the monthly
management fee was based upon the most current population of the Rural Service
Area (RSA) multiplied by $.1042. In 1996, the Partnership paid $45,350 to RCM
which represented a correction in the calculation of the prior year's management
fee paid. On August 24, 1996, the Partnership and RCM agreed upon a termination
fee of $4,000,000 in settlement of the management agreement. As of December 31,
1996, the partnership had paid $2,500,000 to RCM. The balance of the termination
fee, $1,500,000, was paid in August, 1997.
 
NOTE 9--SUBSEQUENT EVENT
 
    On November 17, 1997, the shareholders of Cellular 2000 Telephone Co.
entered into a definitive agreement to sell their stock in Cellular 2000
Telephone Co. and to transfer the Federal Communications Commission (FCC)
Operating Licenses to Dobson Cellular of California, Inc. (Dobson). Cellular
2000 Telephone Co. owns 75.018 percent of the outstanding partnership interests
of Cellular 2000 (A Partnership), and thereby owns a controlling interest in the
Partnership. The financial statements do not reflect any expenses incurred or
expected to be incurred related to the sale. The FCC has consented to the
transfer of control of the Partnership's FCC licenses to Dobson and has granted
authorization to Dobson to operate the cellular telephone system. The sale
closed in April, 1998.
 
    On March 19, 1998, RSA 339, Inc. entered into a definitive agreement to sell
their minority interest in the Partnership to Dobson. RSA 339, Inc. owns the
remaining 24.982 percent of the outstanding partnership interests of the
Partnership. The sale closed in April, 1998.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
Sygnet Wireless, Inc.
 
    We have audited the accompanying consolidated statements of operations,
shareholders' equity (deficit), and cash flows of Sygnet Wireless, Inc. for the
years ended December 31, 1996 and 1997, and for the period from January 1, 1998
through December 23, 1998 (the date of the sale of the Company). 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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated results of operations
and cash flows of Sygnet Wireless, Inc. for the years ended December 31, 1996
and 1997, and for the period from January 1, 1998 through December 23, 1998, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
            FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1997, AND THE
             PERIOD FROM JANUARY 1, 1998 THROUGH DECEMBER 23, 1998
 
1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
 
    These financial statements include the combined financial statements of
Sygnet Communications, Inc. (SYGNET) and Wilcom Corporation (Wilcom) through
August 31, 1996, the effective date of the merger described below and the
accounts of Sygnet Wireless, Inc. and its wholly-owned subsidiary Sygnet
Communications, Inc. (Sygnet) (hereinafter collectively referred to as the
"Company"). Intercompany balances and transactions have been eliminated in the
consolidated financial statements. The Company owns and operates in one segment,
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.
Immediately prior to the merger, 90% of SYGNET's voting interests were owned by
the same individuals as 100% of Wilcom's voting interests. 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-interests 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. SUBSEQUENT EVENT
 
    On December 23, 1998, a wholly-owned subsidiary of Dobson Communications
Corp. (Dobson), acquired all outstanding shares of Class A and B common stock
(including the granted options of the Company as described in Note 11) of the
Company for $337.5 million in cash. In connection with the purchase, the Notes
(as described in Note 5) were tendered for a total price of $1,181.61 for each
$1,000 in principal. The Bank Credit Facility (as described in Note 5) was
repaid and terminated. The Company incurred $7.1 million in merger costs
associated with this business combination. The merger costs included
approximately $4.8 million for an advisory fee and $0.4 million in legal and
accounting fees which are recorded as other non-operating expenses. In addition,
the Company incurred $1.9 million for related employee severance, retention and
stock option plans which are included in costs and expenses.
 
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.

3. ACQUISITIONS (CONTINUED)
    On September 30, 1995, SYGNET, as a general partner, purchased 95.46% of
Erie for cash of $40.53 million. On November 30, 1995, Sharon purchased 4.54% of
Erie for $1.92 million, which was paid on February 12, 1996.
 
    The above transactions were accounted for as purchases and, accordingly, the
results of operations of the companies acquired have been included in the
consolidated financial statements since the date of acquisition.
 
    Cash paid for the acquisitions in 1996 is summarized below:

4. SIGNIFICANT ACCOUNTING POLICIES
 
CASH EQUIVALENTS
 
    The Company considers all liquid investments with a maturity of three months
or less when purchased to be cash equivalents.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are recorded at cost and are depreciated over their
estimated useful lives (ranging from 2.5 to 19 years) calculated under the
straight-line or double declining balance methods.
 
INTANGIBLE ASSETS
 
CELLULAR LICENSES AND CUSTOMER LISTS
 
    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.

4. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Amortization expense was $3,652,470 and $11,559,031 in 1996 and 1997,
respectively, and $11,295,083 for the period from January 1 through December 23,
1998.
 
    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. Measurement of the amount of the
impairment may be based on appraisal, market values of similar assets, or
estimated discounted cash flows reflecting the use and ultimate disposition of
the assets.
 
DEFERRED FINANCING COSTS
 
    Deferred financing costs are being amortized over the terms of the bank
credit facility and senior notes. Amortization expense was $437,276 and
$1,141,065 in 1996 and 1997, respectively, and $1,116,963 for the period from
January 1, 1998 through December 23, 1998. 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 5.
 
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.
 
ADVERTISING COSTS
 
    Advertising costs are recorded as expense when incurred. Advertising expense
was $1,225,151 and $1,841,138 in 1996 and 1997, respectively, and $1,851,047 for
the period from January 1, 1998 through December 23, 1998.
 
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, and related
interpretations.
 
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
48%, 43% and 43% of the Company's Roamer Revenue was earned from two cellular

carriers in 1996 and 1997, and for the period from January 1, 1998 through
December 23, 1998, respectively.
 
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 their obligations under the
agreements.
 
    In June 1998, the Financial Accounting Standards Board issued Statement No.
133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES, which is
required to be adopted in years beginning after June 15, 1999. Because of the
Company's minimal use of derivatives, management does not anticipate that the
adoption of the new Statement will have a significant effect on earnings or the
financial position of the Company.
 
RECLASSIFICATION
 
    Certain 1996 and 1997 amounts have been reclassified to conform with 1998
presentation.
 
5. 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 paid interest
semiannually on April 1 and October 1 of each year commencing April 1, 1997. The
Notes were 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 limited 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. The notes were retired in connection with the sale of the Company
described in Note 2.
 
    On October 9, 1996, Sygnet entered into a new financing agreement (the Bank
Credit Facility) with a commercial bank group. The Bank Credit Facility was a
senior secured reducing revolver that provided Sygnet the ability to borrow up
to $300 million through June 30, 1999. Mandatory reductions in the revolver were
to occur quarterly thereafter through June 30, 2005, when the Bank Credit
Facility was to terminate. The Bank Credit Facility was secured by certain
assets and the stock of Sygnet. The Bank Credit Facility provided for various
borrowing rate options based on either a fixed spread over the London

5. LONG-TERM DEBT (CONTINUED)
Interbank Offered Rate (LIBOR) or the prime rate. Interest payments were made
quarterly. The Bank Credit Facility was retired in connection with the sale of
the Company described in Note 2.
 
    Among other things, the Bank Credit Facility contained financial covenants
which required the maintenance of debt service ratios and the hedging of
interest rate risk and limited 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 agreement converted the interest rate on $80 million notional amount of the
credit facility from a variable rate based upon a three month LIBOR (5.25% at
December 23, 1998) to fixed rates ranging from 5.79% to 6.03%. Amounts paid or
received under these agreements are recognized as adjustments to interest
expense.
 
    Interest paid was $4,691,776 and $30,076,031 in 1996 and 1997, respectively,
and $31,294,880 for the period from January 1, 1998 through December 23, 1998.
 
6. LEASES
 
    The Company has entered into various operating leases for land and office
facilities. Leases for tower sites provide for periodic extensions of lease
periods with future lease payments indexed to the consumer price index.
 
    Rent expense was $906,042 and $2,077,644 in 1996 and 1997, respectively, and
$2,411,310 for the period from January 1, 1998 through December 23, 1998.
 
7. 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. In connection with the
sale of Company described in Note 2, the Plan will be merged with the Dobson
401(k) plan. Total pension expense was $181,000 and $293,000 in 1996 and 1997,
respectively, and $356,747 for the period from January 1, 1998 through December
23, 1998.
 
8. 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 9.
 
    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. No warrants were issued.
For financial reporting purposes, 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.

8. REDEEMABLE PREFERRED STOCK AND WARRANTS (CONTINUED)
 
    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.
 
9. SHAREHOLDERS' EQUITY
 
    On June 20, 1997, the Company issued and sold 3,000,000 shares of Class A
Common Stock, $0.01 par value, to Boston Ventures Limited Partnership V (Boston
Ventures) at a price of $15 per share (Common Stock Sale). The proceeds of $43.6
million, net of issuance fees of $1.4 million, were used to redeem the remaining
outstanding Preferred Stock as described in Note 8 and to reduce amounts
outstanding under the Bank Credit Facility. As a condition of the Common Stock
Sale, 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 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 September 20, 1996. These shares are
entitled to ten votes per share.
 
    Under the most restrictive of the covenants discussed in Note 5, the Company
could not declare any dividends on its common stock through December 23, 1998.
 
    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 required annual payment of interest at 8.23% with
principal repayment commencing on December 31, 1998 through December 31, 2001.
The officer/shareholder repaid 100% of the note and interest accrued on December
29, 1998.
 
10. 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 23, 1998, the Company has net
deferred tax assets of $37.0 million which includes net operating loss
carryforwards of $45.2 million that expire in 2012 and 2013. For financial
reporting purposes, a valuation allowance of $12.6 million has been recognized
to offset the net deferred tax assets related primarily to the net operating
loss carryforwards.

11. 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 APB Opinion 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 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 stock
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 would have
increased by $24,000 and $625,000 from the amounts reported in 1996 and 1997,
respectively, and $419,000 from the amounts reported for the period from January
1, 1998 through December 23, 1998.
 
    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 1996, 1997 and 1998:
risk-free interest rates ranging from 6.9% to 5.9% and average expected lives
ranging from 5.0 to 7.5 years for issued options.

                     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 VII of the Company's Amended and Restated 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:
 
        (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-8
    
<PAGE>
            (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.

behalf by the undersigned, thereunto duly authorized, in the City of Oklahoma

Dobson Communications Corporation
13439 N. Broadway Extension, Suite 200
Oklahoma City, OK

    Re:  12 1/4% Senior Exchangeable Preferred Stock

    Ladies and Gentlemen:

    We have acted as special counsel to Dobson Communications Corporation
("Dobson" or the "Company") in connection with the issuance and sale of 64,646
shares of the Company's 12 1/4% Senior Exchangeable Preferred Stock (which,
together with all accrued and paid dividends in kind are referred to herein as
the "Old Shares") and the registration under the Securities Act of 1933 of up to
67,146 shares of the Company's 12 1/4% Senior Exchangeable Preferred Stock (the
"New Shares"). The New Shares are to be offered in exchange for all outstanding
Old Shares (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, as
amended (Registration No. 333-71633); (the "Registration Statement").

    In this connection we have examined the Company's Amended and Restated
Certificate of Incorporation (including the Certificate of Designation creating
the 12 1/4% Senior Exchangeable Preferred Stock) and Amended and Restated
Bylaws, minutes of certain meetings of the Company's Board of Directors 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 Shares to be
exchanged for the Old Shares in the Exchange Offer, when issued in accordance
therewith, will be validly issued, fully paid and non-assessable.

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

                                          Very truly yours,

                                          /S/ MCAFEE & TAFT

Notice pursuant to Section 12.2(c), in the event that the shares of Class A
Common Stock are not listed or admitted for trading on any national securities
exchange and are not quoted on NASDAQ or any similar service:

              (i)   The Company and the holders of a majority of the outstanding
                    shares of stock being appraised, or any investment bank
                    appointed by them, shall each determine, and attempt to
                    mutually agree upon, the Market Price.

              (ii)  In the event that the parties fail to agree on the Market
                    Price or to mutually agree on an investment bank within 30
                    days then two independent accounting or investment banking
                    firms of nationally recognized standing (each, an
                    "Appraiser"), one chosen by the Company and one by the
                    holders of a majority of the outstanding shares of stock
                    being appraised, shall each determine and attempt to
                    mutually agree upon, the Market Price. Each party shall
                    deliver a notice to the other appointing its Appraiser
                    within 15 days after the expiration of the 30-day period
                    referred to in the prior sentence. If either the Company or
                    such holders fail to appoint an Appraiser within such 15-day
                    period, the Market Price shall be determined by the
                    Appraiser that has been so appointed.

              (iii) If within 30 days after appointment of the two Appraisers
                    they are unable to agree upon the Market Price, an
                    independent accounting or investment banking firm of
                    nationally recognized standing shall within 10 days
                    thereafter be chosen to serve as a third Appraiser by the
                    mutual consent of such first two Appraisers. The
                    determination of the Market Price by the third Appraiser so
                    appointed and chosen shall be made within 30 days after the
                    selection of such third Appraiser.

<PAGE>

              (iv)  If three Appraisers shall be appointed and the determination
                    of one Appraiser is disparate from the middle determination
                    by more than twice the amount by which the other
                    determination is disparate from the middle determination,
                    then the determination of such Appraiser shall be excluded,
                    the remaining two determinations shall be averaged, and such
                    average shall be binding and conclusive on the Company and
                    such holders; otherwise the average of all three
                    determinations shall be binding and conclusive on the
                    Company and such holders.

              (v)   In connection with any appraisal conducted pursuant to this
                    Appraisal Procedure, the Appraisers shall adhere to the
                    guidelines provided in the definition of "Market Price" set
                    forth below, including the proviso thereto.

              (vi)  The fees and expenses of each Appraiser shall be borne
                    one-half by the Company and one-half by such holders.

                            MANAGEMENT OF THE COMPANY

     3.1      BOARD OF DIRECTORS. (a) The Board of Directors shall, subject to
the other 

<PAGE>

provisions hereof, consist of seven (7) directors; PROVIDED, HOWEVER, that the
number of directors constituting the Board of Directors shall be reduced in the
circumstances set forth in this Section 3.1. Each of the Stockholders hereby
agrees that it will vote all of the shares of its Common Stock and Preferred
Stock (to the extent entitled to vote) owned or held of record by it (whether
now owned or hereafter acquired), in person or by proxy, to cause the election
of directors and thereafter the continuation in office of such directors as
follows:

              (i)   one director selected by JWC, in its sole discretion, so 
long as it Beneficially Owns at least 35% of the Class D Preferred Stock (or the
Class A Common Stock or Class E Preferred Stock acquired upon conversion
thereof) it holds as of the Amendment and Restatement Date;

              (ii)  one director selected by AT&T, in its sole discretion, so
long as it Beneficially Owns at least 50% of the Class D Preferred Stock (or the
Class A Common Stock or Class E Preferred Stock acquired upon conversion
thereof) it holds as of the Amendment and Restatement Date, subject to section
3.1(b);

              (iii)  four directors selected by the Dobson Partnership, in its
sole discretion; and

              (iv)   one director jointly selected by JWC, AT&T (in the event 
its designee is a member of the current Board of Directors) and the Dobson
Partnership, subject to Section 3.1(b). In the event that AT&T shall have
relinquished, and shall continue to relinquish, its right to designate a
director under Section 3.1(a)(ii) in accordance with Section 3.1(b), then the
director jointly selected by JWC and the Dobson Partnership pursuant to this
Section 3.1(a)(iv) shall be reasonably acceptable to AT&T, which consent shall
not be unreasonably withheld.

              Each of JWC and AT&T (in the event its designee is a member of the
current Board of Directors) shall have the right to, so long as they hold their
respective Relevant Percentage Interest, designate one director for the Board of
Directors of each Subsidiary of the Company.

              If, for any reason, any director to be designated pursuant to
clause (iv) hereof is not designated within 45 days of the time when such
designation right arises, then (x) such director will be jointly selected by JWC
and AT&T (in the event its designee is a member of the current Board of
Directors), and (y) if any such director is not designated pursuant to clause
(x) within 90 days of such time, then such director will be selected by the
Dobson Partnership. In the event that any Class D Preferred Stock is converted
into Class A Common Stock and Class E Preferred Stock in accordance with the
terms thereof, the rights of the holders of such Preferred Stock to vote to
appoint directors in accordance with the terms hereof shall survive such
conversion.

<PAGE>

              Any nomination or designation of directors and the acceptance
thereof pursuant to Section 3.1 shall be evidenced in writing.

              (b) If, for any reason, AT&T's director selected pursuant to
clause (a)(ii) above resigns or AT&T determines that it no longer desires to
have director designation rights, including as a result of a Conflict and the
related provisions herein, then AT&T may, at its option, relinquish such
director designation rights, in which case, an additional director will be
designated pursuant to Section 3.1(a)(iv) above and AT&T will be entitled to
observer rights as provided in Section 3.1(d) below, PROVIDED, that if AT&T
subsequently determines to reinstate such director designation rights, it may do
so by notifying the parties hereto, in which case, such observer rights will
terminate, AT&T's director designation rights in Section 3.1(a)(ii) will be
reinstated, and the additional director designated pursuant to this Section
3.1(b) and 3.1(a)(iv) will concurrently resign or be removed.

              (c) The Stockholders acknowledge the rights of the holders of
Senior PIK Preferred Stock to designate an additional 2 directors, the right of
the holders of Sygnet PIK Preferred Stock to designate an additional 2 directors
and the right of the holders of the Class F Preferred Stock to designate one
additional director, in the event that the triggering events described in
paragraph (iii) of the Senior PIK Preferred Stock Certificate of Designation,
paragraph (iii) of the Sygnet PIK Preferred Stock Certificate of Designation,
and subparagraph (c)(iii) of the Class F Preferred Stock Certificate of
Designation, respectively occur.

              (d) If AT&T relinquishes its director designation rights pursuant
to Section 3.1(b), then AT&T will be entitled to designate an observer in
addition to its observer appointed under Section 3.4, who will be entitled to
attend all meetings of the Board of Directors and receive the same notice and
information provided to members of the Board of Directors. The Company will
reimburse the observer appointed pursuant to this Section in connection with
such person's role as observer for the reasonable and documented out-of-pocket
expenses and costs (including travel expenses), incurred by such observer in
connection with the performance of his service as an observer of the Board of
Directors.

     3.2      REMOVAL; FILLING OF VACANCIES. Except as set forth in Section 3.1,
each Stockholder agrees it will not vote any shares of Company Stock
Beneficially Owned by such Stockholder, and shall not permit any Affiliated
Successor of such Stockholder holding any Company Stock, to vote for the removal
without cause of any director designated by any other Stockholder in accordance
with Section 3.1. Any Stockholder or group of Stockholders who has the right to
designate any member(s) of the Board of Directors shall have the right to
replace any member(s) so designated by it (whether or

<PAGE>

not such member is removed from the Board of Directors with or without cause or
ceases to be a member of the Board of Directors by reason of death, disability
or for any other reason) upon written notice to the other Stockholders, the
Company and the members of the Board of Directors which notice shall set forth
the name of the member(s) being replaced and the name of the new member(s). Each
of the Stockholders agrees to vote, and to cause its Affiliated Successors to
vote, its shares of Preferred Stock and Common Stock, or shall otherwise take
any action as is necessary to cause the election of any successor director
designated by any Stockholder pursuant to this Section 3.2.

     3.3      DIRECTORS. In accordance with the Oklahoma General Corporation Law
and pursuant to the provisions of Section 3.1 of this Agreement, the
Stockholders hereby consent to the election of and do hereby elect in accordance

are duly elected and qualified, except as otherwise provided in this Agreement,

     3.4      COMPENSATION AND REIMBURSEMENT. The members of the Board of
Directors (other than the director selected pursuant to Section 3.1(a)(iv))
shall not be compensated for their services as a director or as a member of any
committee of the Board of Directors. For so long as JWC Beneficially Owns at
least 35% and AT&T Beneficially Owns at least 50%, respectively, of the number
of shares of Class D Preferred Stock (or any Class A Common Stock or Class E
Preferred Stock into which it may have been converted) which JWC or AT&T, as the
case may be, owns as of the Amendment and Restatement Date (the "Relevant
Percentage Interests"), JWC and AT&T shall each have the right to have an
observer present at all meetings of the Board of Directors and any committees
thereof (in addition to any directors appointed pursuant to Sections 3.1(a)(i)
and (ii) above). The Company will reimburse the observers appointed pursuant to
this Section and each member of the Board of Directors for the reasonable and
documented out-of-pocket expenses and costs (including travel expenses) incurred
by such observers or such directors in connection with the performance by each
such person of his service as an observer or as a director or as a member of any

in the Tag-Along Notice for up to such number of shares of Tag-Along Stock as is
determined in accordance with this Section 4.2, by furnishing written notice of
such acceptance to each Selling Stockholder, and delivering, to an escrow agent
(which shall be a bank or a law or accounting firm designated by the Company),
on behalf of the Selling Stockholders, the certificate or certificates
representing the shares of Tag-Along Stock to be sold pursuant to such offer by
each Stockholder, duly endorsed in blank, together with a limited power-of-
attorney authorizing the escrow agent, on behalf of the Stockholder, to sell the
shares to be sold pursuant to the terms of such Tag-Along Event Purchaser's
offer.

         If any Stockholder desires to sell less than its proportionate amount
of shares of Tag-Along Stock that it is entitled to sell pursuant to this
Section 4.2, then each of the other Stockholders shall have the right to sell to
the Tag-Along Event Purchaser an additional amount of shares of Tag-Along Stock
as shall be calculated in accordance with the allocations and procedures set
forth in the immediately preceding paragraph. Such process shall be repeated in
series until all of the remaining Stockholders agree to sell their remaining
proportionate number of shares of Tag-Along Stock.

         Schedule IV sets forth an illustrative example for this Section 4.2(a),
PROVIDED, HOWEVER, that in the event of any conflict between such illustration
and this Section 4.2, Section 4.2 shall govern.

<PAGE>

              (b) The purchase from each Tag-Along Event Offeree pursuant to
this Section 4.2 shall be on the same terms and conditions, including the price
per share received by the Selling Stockholders and stated in the Tag-Along
Notice provided to each Stockholder. In the event that the Tag-Along Stock is
Common Stock, all Stockholders shall be required, as a condition of 
participating in such transaction (in cases where the Preferred Stock is 
convertible into Common Stock), to convert the required amount of its Preferred
Stock into Common Stock and Transfer Common Stock to the Tag-Along Event
Purchaser.

               (c) Simultaneously with the consummation of the sale of the
shares of Tag-Along Stock to the Tag-Along Event Purchaser pursuant to the
Tag-Along Event Purchaser's offer, the Selling Stockholders shall notify each
Stockholder and shall cause the Tag-Along Event Purchaser to remit to each
Stockholder the total sales price of the shares of Tag-Along Stock held by each
Stockholder sold pursuant thereto and shall furnish such other evidence of the
completion and time of completion of such sale and the terms thereof as may be
reasonably requested by each Stockholder.

               (d) If within thirty (30) days after receipt of the Tag-Along
Notice, a Stockholder has not accepted the offer contained in the Tag-Along
Notice, such Stockholder shall be deemed to have waived any and all rights with
respect to the sale described in the Tag-Along Notice (but not with respect to
any subsequent sale, to the extent this Section 4.2 is applicable to such
subsequent sale) and the Selling Stockholders shall have sixty (60) days from
the initial delivery of the last Tag-Along Notice in which to sell not more than
the number of shares of Tag-Along Stock described in the Tag-Along Notice, on
terms not more favorable to the Selling Stockholders than were set forth in the
Tag-Along Notice; PROVIDED, HOWEVER, that if such purchase is subject to the
consent of the FCC or any public service or public utilities commission, the
purchase of such shares shall be closed on the first business day after all such
consents shall have been obtained by Final Order.

               (e) Without limiting Section 4.1(a), Section 4.2 will not apply
to (i) Transfers of Company Stock made after the IPO Date in a public offering
in accordance with Section 5 or pursuant to Rule 144, (ii) subject to Section
6.12.8, the sale or redemption of up to $25.0 million in aggregate principal
amount by the Dobson Partnership of Company Stock, together with any dividends
thereon, in one transaction or a series of transactions, (iii) the sale of any
Class F Preferred Stock; (iv) any transfer pursuant to Section 4.1(a)(i), (ii),
(iii) or (v) hereof (and similar Transfers of Fleet Buyout Stock); and (v)
transfers by any JWC Group Stockholder or AT&T after the earliest to occur of
(A) the IPO Date, (B) December 23, 2003 or (C) a Change of Control.

     4.3      ADDITIONAL CONDITIONS TO PERMITTED TRANSFERS.

              (a) As a condition to any Transfer to an Affiliated Successor
permitted pursuant to Section 4.1, or any Transfer pursuant to Section 4.2, each
transferee that is not a party hereto shall, prior to such Transfer, agree in
writing to be bound by all of the provisions of this Agreement applicable to the
Stockholders (and shall thereby become a Stockholder for all purposes of this
Agreement). Any Transfer without compliance with such provisions of this
Agreement shall be null and void and such transferee shall have no rights as a
Stockholder of the Company.

               (b) Notwithstanding anything to the contrary contained in this
Agreement (other than the next sentence) each Stockholder agrees that it will
not effect a Transfer of shares of Company Stock to a Prohibited Transferee. In
the event that the Dobson Partnership Transfers any Preferred Stock or Common
Stock to a Prohibited Transferee, JWC and AT&T shall equally be entitled to
transfer such securities to such Person pursuant to Section 4.2. It shall be
deemed a breach of this Section 4.3(b) by a Stockholder Beneficially Owning more
than 10% of the Common Stock outstanding if any Prohibited Transferee shall
acquire, directly or indirectly, in a private sale Beneficial Ownership of more
than 331/3% of any class of equity securities or equity interest in, such
Stockholder and the Dobson Partnership shall not have Transferred any shares of
Company Stock to such Prohibited Transferee.

               (c) Notwithstanding anything to the contrary contained in this
Agreement, the Dobson Partnership shall not, nor shall it permit any of its
Affiliates (other than the Company) to, sell any shares of Company Stock to a
Major Telecom Competitor, unless such Major Telecom Competitor makes an
irrevocable offer to AT&T and its Affiliates to purchase from them, at the same
price and otherwise on the same terms and conditions as the sale to such Major
Telecom Competitor by the Dobson Partnership or such Affiliate, up to all of the
shares of Company Stock Beneficially Owned by AT&T and its Affiliates. At any
time within 14 days after receipt by AT&T of the Tag-Along Notice with respect
to such sale, AT&T may accept such offer and, to the extent AT&T and its
Affiliates elect to accept such offer, concurrently with the consummation of any
such sale by the Dobson Partnership or such Affiliate, the sale of all of At&T's
shares of Tag-Along Stock in respect of which it accepted such offer shall be
consummated. The provisions of this Section 4.3(c) shall not apply to any
transferees or assigns of AT&T.

     4.4      STOP-TRANSFER. The Company agrees not to effect any Transfer of
shares of Company Stock by any Stockholder whose proposed Transfer is subject to
Section 4.2 until it has received evidence reasonably satisfactory to it that
the rights provided to any other Stockholders pursuant to such Section, if
applicable to such Transfer, have been complied with and satisfied in all
respects. No Transfer of any shares of Preferred Stock and/or Common Stock shall
be made except in compliance with all applicable securities laws. Any Transfer
made in violation of this Agreement shall be null and void.

<PAGE>

     4.5      DRAG ALONG RIGHTS. If at any time the Board of Directors shall
approve the sale or exchange (in a business combination or otherwise) by
Stockholders of Common Stock and Class D Preferred Stock and Class E Preferred
Stock of the Company in a bona fide arm's-length transaction to a third party
pursuant to an agreement that (i) treats equally, on an "as-if-converted basis,"
the value of all holders of Common Stock, Class D Preferred Stock and Class E
Preferred Stock, except as provided in the Restated Certificate of
Incorporation, (ii) is approved by the Board of Directors as fair to all
Stockholders, and (iii) which shall have been approved by Stockholders holding
50.1% of the outstanding Common Stock of the Company on an as-if-converted
basis, then, upon the written request of the Company, each Stockholder shall be
obligated to, and shall, if so requested by such third party, (a) sell, transfer
and deliver or cause to be sold, transferred and delivered to such third party,
shares of Common Stock and Preferred Stock owned by such Stockholder, and (b) if
Stockholder approval of the transaction is required, vote his, her or its shares
of Company Stock in favor thereof. Notwithstanding the previous sentence, a Cash
Equity Investor may not be obligated to sell any shares of Class D Preferred
Stock or Class E Preferred Stock unless it receives as consideration for such
shares at least their Liquidation Preference and it may not be obligated to sell
any shares of Common Stock unless all of the shares of Class D Preferred Stock
or Class E Preferred Stock then held by such Cash Equity Investors are to be
sold for cash in such transaction.

     4.6      REDEMPTION RIGHTS. Subject to the terms of the Financing 
Agreements and not giving rise to either a default or an event of default
thereunder, the Class D Preferred Stock (or Class E Preferred Stock) will be
redeemed within 90 days following the vote of holders of a majority of the
outstanding shares of the Class D Preferred Stock (or Class E Preferred Stock as
the case may be), at any time (a) after twelve years from the date of this
Agreement or (b) upon the completion of an IPO by the Company of Common Stock.
Upon redemption of Class D Preferred Stock, the holders of Class D Preferred
Stock so redeemed will receive a cash payment equivalent to the then current
Liquidation Preference per share plus the number of shares of Class A Common
Stock such holders would have received had they converted such Class D Preferred
Stock into shares of Class E Preferred Stock and Class A Common Stock
immediately prior to such redemption.

     4.7      RIGHT OF FIRST REFUSAL FOR NEW SECURITIES; CAPITAL RAISING.

              (a) The Company hereby grants to each of JWC and AT&T, on the
same terms and conditions, a right of first refusal, to the extent necessary to
maintain their ownership in the Company on a Fully Diluted Basis, to purchase
shares of any New Securities (as defined below) which the Company may, from time
to time, propose to issue and sell to private equity investors (and not through
a public offering or a private 

<PAGE>

placement (which provides for registration within one year of issuance)/Rule
144A offering, which, together with any supplemental or additional offerings,
results in gross proceeds in excess of $50.0 million). Such right of first
refusal shall allow each of JWC and AT&T to purchase a pro rata portion
necessary to maintain such ownership on a Fully Diluted Basis of the New
Securities proposed to be issued, determined with reference to the aggregate
number of outstanding shares of Common Stock (on an as-if-converted basis) held
by JWC and AT&T as the case may be, before the proposed issuance of New
Securities. The right of first refusal granted hereunder may be exercised by
either of JWC or AT&T as to themselves and shall terminate if unexercised within
30 calendar days after receipt of notice from the Company to the Cash Equity
Investors.

               (b) "New Securities" shall mean any authorized but unissued
shares, and any treasury shares, of preferred stock or common stock of the
Company and all rights, options or warrants to purchase common stock, and
securities of any type whatsoever that are, or may become, convertible into
common stock; PROVIDED, HOWEVER, that the term "New Securities" does not include
(i) shares of Common Stock or stock options issued to officers, employees,
directors, consultants of the Company or others in connection with their
services pursuant to a plan or plans approved by the Board of Directors; (ii)
securities issued upon conversion of shares of Class D Preferred Stock to Class
A Common Stock and Class E Preferred Stock or shares issued upon the conversion
of any Class G Preferred Stock for Class H Preferred Stock; (iii) securities
issued by the Company pursuant to the acquisition of another corporation by the
Company by merger, purchase of all or substantially all of the assets or other
reorganization whereby the Company shall become the owner of more than 50% of
the voting power of such corporation; (iv) shares of Common Stock issued in
connection with any stock split or stock dividend of the Company; (v) capital
stock (including warrants, options or other rights to purchase capital stock, or
that are convertible into or exchangeable for capital stock of the Company)
issued directly in connection with any borrowings or the incurrence of any
indebtedness by the Company or its Subsidiaries in connection with acquisitions
or capital projects; (vi) shares of Class A Common Stock issued pursuant to any
IPO in excess of $50.0 million (taken together with any supplemental or
additional offerings) or Rule 144A promulgated thereunder which provide for
registration of such Capital Stock within one year of their issuance; or (vii)
shares issuable upon exercise of the Sygnet PIK Preferred Stock Warrants.

               (c) If the Company or any Subsidiary in the future proposes to
raise private equity capital it shall provide JWC with the terms of such
proposal prior to approaching other potential investors and shall grant JWC the
initial opportunity to make any such investment, PROVIDED that nothing herein
shall require the Company to enter into any agreement or sale with the Company
as to such private equity capital on terms less favorable than the prevailing
market terms and rates offered to comparable companies to the Company. If JWC
determines to provide such private equity capital,

<PAGE>

then JWC will make available to AT&T its pro rata portion thereof, determined by
reference to their respective holdings of Company Stock on a Fully Diluted Basis
in the Company at the Amendment and Restatement Date, on similar terms and
conditions as provided by JWC.


                                   ARTICLE 5.

                               REGISTRATION RIGHTS

     The Company will not grant registration rights for Company capital stock to
a Person other than the Cash Equity Investors on terms pari passu with or senior
to or more favorable than those granted to the Cash Equity Investors.

     (a) DEMAND REGISTRATION RIGHTS.

           (i) RIGHT TO DEMAND REGISTRATION.  At any time following 180 days 
after the IPO Date (or such longer period as may be reasonably required by the
managing underwriters of the Company's IPO) and (A) the Dobson Partnership
shall have the right to make one written request, and (B) JWC shall have the
right to make two written requests, and (C) AT&T shall have the right to make
one written request (each, a "Demanding Stockholder" and, collectively, the
"Demanding Stockholders") to the Company for registration with the Commission,
under and in accordance with the provisions of the Securities Act, of all or
part of their Registrable Securities pursuant to an underwritten offering (a
"Demand Registration"), which request shall specify the number of Registrable
Securities proposed to be sold in the offering; PROVIDED, HOWEVER, that (x) the
Company need not effect a Demand Registration unless the sale of the Registrable
Securities proposed to be sold by the Demanding Stockholder shall reasonably be
expected to result in aggregate gross proceeds of at least $25.0 million, and
(y) if the Board of Directors determines that a Demand Registration would
interfere with any pending or contemplated material acquisition, disposition,
financing or other material transaction, the Company may defer a Demand
Registration (including by withdrawing any Registration Statement filed in
connection with a Demand Registration); so long as that the aggregate of all
such deferrals shall not exceed ninety (90) days in any 360-day period. A Demand
Registration shall not be deemed a Demand Registration hereunder until such
Demand Registration has been declared effective by the Commission (without
interference by any stop order, injunction or other order or requirement of the
Commission or other governmental agency, for any reason), and maintained
continuously effective for a period of at least six (6) months or such shorter
period when all Registrable Securities included therein have been sold in
accordance with such Demand Registration. A Demanding Stockholder may make a
written request for a Demand Registration in accordance with the foregoing in
respect of Company Stock that it intends to convert into shares of Common Stock
upon the 

<PAGE>

effectiveness of the Registration Statement prepared in connection with such
demand, and the Company shall fulfill its obligations under this Article 5 in a
manner that permits such Demanding Stockholder to exercise its conversion rights
in respect of such Company Stock and substantially contemporaneously sell the
shares of Common Stock issuable upon such conversion under such Registration
Statement.

     In addition to the rights set forth above, each of the Demanding 
Stockholders shall have the right to demand that the Company file a registration
statement on Form S-3 (or any successor form to Form S-3) for an offering of
Registrable Securities in which at least $15.0 million of gross proceeds are
reasonably expected therefrom, PROVIDED that the Company is not obligated to
participate in any "road-show" or exceptional marketing, diligence or other
efforts in connection with such offering. This additional demand registration
may be a one year "shelf-registration." The procedures and limitations for
effecting the registration of the Registrable Securities on Form S-3 (or any
successor form to Form S-3), including the procedure used for any underwriting
limitation, shall be as set forth in this Article 5.

              Within ten (10) days after receipt of the request for a Demand
Registration, the Company will send written notice (the "Demand Notice") of such
Registration request and its intention to comply therewith to all Stockholders
who are holders of Registrable Securities and, subject to Section 5(a)(ii), the
Company will include in such Demand Registration all Registrable Securities of
such Stockholders with respect to which the Company has received written
requests for inclusion therein within twenty (20) days after the last date such
Demand Notice was deemed to have been given pursuant to Section 14.1.

              (ii) PRIORITY ON REGISTRATION. If the managing underwriter or
underwriters advise the Company and the holders of the Registrable Securities to
be registered in writing that in its or their opinion the number of Registrable
Securities proposed to be sold in any Registration (including, without
limitation, a Piggyback Registration) and any other securities of the Company
requested or proposed to be included in such Registration exceeds the number
that can be sold in such offering without (A) creating a substantial risk that
the proceeds or price per share that will be derived from such Registration will
be materially reduced or that the number of Registrable Securities to be
registered is too large a number to be reasonably sold, or (B) materially and
adversely affecting such Registration in any other respect, the Company will (x)
include in such Registration the aggregate number of Registrable Securities
recommended by the managing underwriter (the number of Registrable Securities to
be registered for each Stockholder to be reduced FIRSTLY, against the Dobson
Partnership, SECONDLY, against the other Stockholders (other than JWC and AT&T)
and LASTLY, against JWC and AT&T; in each case PRO RATA based on the amount of
Registrable Securities of the Stockholders in the applicable class requested to
be included in such Registration), and (y) not allow any securities other than
Registrable Securities to be included in such 

<PAGE>

Registration unless all Registrable Securities requested to be included shall
have been included therein, and then only to the extent recommended by the
managing underwriter or determined by the Company after consultation with an
investment banker of nationally recognized standing (notification of which
number shall be given by the Company to the holders of Registrable Securities).

              (iii) SELECTION OF UNDERWRITERS. The offering of such
Registrable Securities pursuant to such Demand Registration shall be in the form
of an underwritten offering. The Demanding Stockholder that initiated such
Demand Registration will select a managing underwriter or underwriters of
recognized national standing to administer the offering, which managing
underwriter or underwriters shall be reasonably acceptable to the Company.

     (b) PIGGYBACK REGISTRATION RIGHTS.

              RIGHT TO PIGGYBACK. If the Company proposes to register any
shares of Common Stock (or securities convertible into or exchangeable for
Common Stock) with the Commission under the Securities Act (other than a
Registration on Form S-4 or Form S-8, or any successor forms), and the
Registration form to be used may be used for the Registration of the Registrable
Securities (a "Piggyback Registration"), the Company will give written notice (a
"Piggyback Notice") to all Stockholders, at least thirty (30) days prior to the
anticipated filing date, of its intention to effect such a Registration, which
notice will specify the proposed offering price (if determined at that time),
the kind and number of securities proposed to be registered, the distribution
arrangements and will, subject to Section 5(a)(ii), include in such Piggyback
Registration all Registrable Securities with respect to which the Company has
received written requests (which requests have not been withdrawn) for inclusion
therein within twenty (20) days after the last date such Piggyback Notice was
deemed to have been given pursuant to Section 15.1. If at any time after giving
the Piggyback Notice and prior to the effective date of the Registration
Statement filed in connection with such Registration, the Company determines for
any reason not to register or to delay Registration, the Company may, at its
election, give written notice of such determination to each holder of
Registrable Securities that has requested inclusion of Registrable Securities in
such Registration and (A) in the case of a determination not to register, shall
be relieved of its obligation to register any Registrable Securities in
connection with such Registration, and (B) in the case of a determination to
delay registering, shall be permitted to delay registering any Registrable
Securities for the same period as the delay in registering such other
securities.

              No Stockholder may obtain a Piggyback Registration on a Demand
Registration initiated by JWC or AT&T except that each of AT&T and JWC may
Piggyback on the Demand Registrations of the other; PROVIDED that, in such
circumstances, any reduction requested by the managing underwriter(s) in such

<PAGE>

registration in the number of Registrable Securities to be registered shall
first be applied to the party seeking to Piggyback on the Demand Registration.

     (c) SELECTION OF UNDERWRITERS. Except as set forth in Section 5.1(a)(iii),
the Company (by action of the Board of Directors) will select the managing
underwriter or underwriters to administer offerings of its capital stock, which
managing underwriter or underwriters will be of nationally recognized standing.

     (d) REGISTRATION PROCEDURES. With respect to any Demand Registration or 
Piggyback Registration (each, a "Registration"), the Company shall, subject to
Sections 5(a)(i) and (5)(a)(ii) and Section 5(b)(i), as expeditiously as
practicable:

              (i)   prepare and file with the Commission, as promptly as
reasonably practicable (but in no event more than forty-five (45) days) after
the receipt of the Registration requests under Sections 5(a) or 5(b), a
registration statement or registration statements (each, a "Registration
Statement") relating to the applicable Registration on any appropriate form
under the Securities Act, which form shall be available for the sale of the
Registrable Securities in accordance with the intended method or methods of
distribution thereof; cooperate and assist in any filings required to be made
with the NASD; and use its reasonable best efforts to cause such Registration
Statement to become and (to the extent provided herein) remain effective;
PROVIDED, HOWEVER, that before filing a Registration Statement or prospectus
related thereto (a "Prospectus") or any amendments or supplements thereto, the
Company shall furnish to the holders of the Registrable Securities covered by
such Registration Statement and the underwriters, if any, copies of all such
documents proposed to be filed, which documents will be subject to the
reasonable review of such holders and underwriters and their respective counsel,
and the Company shall not file any Registration Statement or amendment thereto
or any Prospectus or any supplement thereto to which the holders of a majority
of the Registrable Securities covered by such Registration Statement or the
underwriters, if any, shall reasonably object;

              (ii)  prepare and file with the Commission such amendments and
supplements to the Registration Statement as may be necessary to keep each
Registration Statement effective for six (6) months (nine (9) months in the case
of any shelf registration requested by a Qualified Holder pursuant to this
Section 5) or such shorter period that will terminate when all Registrable
Securities covered by such Registration Statement have been sold; cause each
Prospectus to be supplemented by any required Prospectus supplement, and as so
supplemented to be filed pursuant to Rule 424 under the Securities Act; and
comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such Registration Statement during the applicable
period in accordance with the intended method or methods of distribution by the
sellers thereof set forth in such Registration Statement or supplement to the
Prospectus;

<PAGE>

              (iii) promptly notify the selling holders of Registrable
Securities and the managing underwriters, if any (and, if requested by any such
Person or entity, confirm such advice in writing), (A) when the Prospectus or
any Prospectus supplement or post-effective amendment has been filed, and, with
respect to the Registration Statement or any post-effective amendment, when the
same has become effective; (B) of any request by the Commission for amendments
or supplements to the Registration Statement or the Prospectus or for additional
information; (C) of the issuance by the Commission of any stop order suspending
the effectiveness of the Registration Statement or the initiation of any
proceedings for that purpose; (D) if at any time the representations and
warranties of the Company contemplated by subsection (xiv) of this subsection
(d) below cease to be true and correct; (E) of the receipt by the Company of any
notification with respect to the suspension of the qualification of the
Registrable Securities for sale under the securities or blue sky laws of any
jurisdiction or the initiation or threatening of any proceeding for such
purpose; and (F) of the happening of any event which makes any statement made in
the Registration Statement, the Prospectus or any document incorporated therein
by reference untrue or which requires the making of any changes in the
Registration Statement, the Prospectus or any document incorporated therein by
reference in order to make the statements therein not misleading;

              (iv)  use its reasonable best efforts to obtain the withdrawal of
any order suspending the effectiveness of (I) the Registration Statement, or
(II) the qualification of the Registrable Securities for sale under the
securities or blue sky laws of any jurisdiction at the earliest possible time;

              (v)   if requested by the managing underwriter or underwriters or 
a holder of Registrable Securities being sold in connection with an underwritten
offering, promptly incorporate in a Prospectus supplement or post-effective
amendment such information as the managing underwriters and the holders of a
majority of the Registrable Securities being sold agree should be included
therein relating to the plan of distribution with respect to such Registrable
Securities, including, without limitation, information with respect to the
number of Registrable Securities being sold to such underwriters, the purchase
price being paid therefor by such underwriters and any other terms of the
underwritten (or best efforts underwritten) offering of the Registrable
Securities to be sold in such offering; and make all required filings of such
Prospectus supplement or post-effective amendment as soon as notified of the
matters to be incorporated in such Prospectus supplement or post-effective
amendment;

              (vi)  furnish to each selling holder of Registrable Securities and
each managing underwriter, without charge, at least one signed copy of the
Registration Statement and any amendment thereto, including financial statements
and schedules, all documents incorporated therein by reference and all exhibits
(including those incorporated by reference);

<PAGE>

              (vii) deliver to each selling holder of Registrable Securities 
and the underwriters, if any, without charge, as many copies of the Prospectus
(including each preliminary prospectus) and any amendment or supplement thereto
as such selling holder of Registrable Securities underwriters may reasonably
request in order to facilitate the public sale or other disposition of the
securities owned by such selling holder;

              (viii) prior to any public offering of Registrable Securities,
use its reasonable best efforts to register or qualify or cooperate with the
selling holders of Registrable Securities, the underwriters, if any, and their
respective counsel in connection with the Registration or qualification of such
Registrable Securities for offer and sale under the securities or "blue sky"
laws of such jurisdictions in the United States as any seller or underwriter
reasonably requests in writing, use its reasonable best efforts to obtain all
appropriate registrations, permits and consents required in connection
therewith, and do any and all other acts or things reasonably necessary or
advisable to enable the disposition in such jurisdictions of the Registrable
Securities covered by the Registration Statement; PROVIDED, HOWEVER, that the
Company will not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified or to take any action that would
subject it to taxation or general service of process in any such jurisdiction
where it is not then so subject;

              (ix)  cooperate with the selling holders of Registrable Securities
and the managing underwriters, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and not
bearing any restrictive legends and to be in such denominations and registered
in such names as the managing underwriters may request at least two (2) business
days prior to any sale of Registrable Securities to the underwriters;

              (x)   use its reasonable best efforts to cooperate with any 
selling holder to cause the Registrable Securities covered by the applicable
Registration Statement to be registered with or approved by such other
governmental agencies or authorities in the United States as may be necessary to
enable the seller or sellers thereof or the underwriters, if any, to consummate
the disposition of such Registrable Securities;

              (xi)  upon the occurrence of any event contemplated by subsection
(iii)(F) above, promptly prepare a supplement or post-effective amendment to the
Registration Statement or the related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to the purchasers of the Registrable Securities, the Prospectus will
not contain an untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein not misleading;



<PAGE>

              (xii) cause all Registrable Securities covered by any Registration
Statement to be listed on each securities exchange on which similar securities 
issued by the Company are then listed, or, if not so listed, cause such
Registrable Securities to be authorized for trading on the NASDAQ National
Market System if any similar securities issued by the Company are then so
authorized, if requested by the holders of a majority of such Registrable
Securities or the managing underwriters, if any;

              (xiii) not later than the effective date of the applicable
Registration, provide a CUSIP number for all Registrable Securities;

              (xiv) enter into such customary agreements (including in the case
of a Demand Registration that is an underwritten offering, an underwriting
agreement in customary form) and take all such other actions reasonably required
in connection therewith in order to expedite or facilitate the disposition of
such Registrable Securities and in such connection, whether or not an
underwriting agreement is entered into and whether or not the Registration is an
underwritten Registration, (A) make such representations and warranties to the
holders of such Registrable Securities and the underwriters, if any, in form,
substance and scope as are customarily made by issuers to underwriters in
primary underwritten offerings; (B) use reasonable best efforts to obtain
opinions of counsel to the Company and updates thereof (which opinions of
counsel shall be in form, scope and substance reasonably satisfactory to the
managing underwriters, if any, and to the holders of a majority of the
Registrable Securities being sold), addressed to each selling holder and the
underwriters, if any, covering the matters customarily covered in opinions
requested in underwritten offerings and such other matters as may be reasonably
requested by such holders and underwriters; (C) use reasonable best efforts to
obtain "cold comfort" letters and updates thereof from the Company's independent
certified public accountants addressed to the selling holders of Registrable
Securities and the underwriters, if any, such letters to be in customary form
and covering matters of the type customarily covered in "cold comfort" letters
by underwriters in connection with primary underwritten offerings; and (D)
deliver such documents and certificates as may be reasonably requested by the
holders of a majority of the Registrable Securities being sold and the managing
underwriters, if any, to evidence compliance with subsection (xi) above and with
any customary conditions contained in the underwriting agreement or other
agreement entered into by the Company. All the above in this Section 5(d)(xiv)
shall be done at each closing under each underwriting or similar agreement or as
and to the extent required thereunder;

              (xv)  make available for inspection by a representative of each
Demanding Stockholder or selling holder, any underwriter participating in any
disposition pursuant to such Registration, and any attorney or accountant
retained by the sellers or underwriter, copies or extracts of all financial and
other records, pertinent 

<PAGE>

corporate documents and properties of the Company as shall be reasonably
necessary, in the opinion of the holders' or underwriter's counsel, to enable
them to fulfill their due diligence responsibilities; and cause the Company's
officers, directors and employees to supply all information reasonably requested
by any such representative, underwriter, attorney or accountant in connection
with such Registration Statement; PROVIDED, HOWEVER, that the Company shall not
be required to comply with this paragraph (xv) unless such Person executes
confidentiality agreements whereby such person agrees that any records,
information or documents that are designated by the Company in writing as
confidential shall be kept confidential by such Persons and used only in
connection with the proposed Registration unless disclosure of such records,
information or documents is required by court or administrative order or any
regulatory body having jurisdiction; and each seller of Registrable Securities
agrees that it will, upon learning that disclosure of such records, information
or documents is sought in a court of competent jurisdiction or by a governmental
agency, give notice to the Company and allow the Company, at the Company's
expense, to undertake appropriate action to prevent disclosure of any records,
information or documents deemed confidential; PROVIDED FURTHER, HOWEVER,
notwithstanding any designation of confidentiality by the Company, confidential
information shall not include information which (i) becomes generally available
to the public other than as a result of a disclosure by or on behalf of any such
Person, or (ii) becomes available to any such Person on a non-confidential basis
from a source other than the Company or its advisors, PROVIDED that such source
is not to such Person's knowledge bound by a confidentiality agreement with or
other obligations of secrecy to the Company or another party with respect to
such information;

              (xvi) otherwise use its reasonable best efforts to comply with
all applicable rules and regulations of the Commission, and make generally
available to its security holders, earnings statements satisfying the provisions
of Section 11(a) of the Securities Act, no later than forty-five (45) days after
the end of any twelve (12)-month period (or ninety (90) days, if such period is
a fiscal year) (A) commencing at the end of any fiscal quarter in which
Registrable Securities are sold to underwriters in a firm or best efforts
underwritten offering, or (B) if not sold to underwriters in such an offering,
beginning with the first month of the Company's first fiscal quarter commencing
after the effective date of the Registration Statement, which statements shall
cover said twelve (12)-month periods; and

              (xvii) promptly prior to the filing of any document that is to be
incorporated by reference into any Registration Statement or Prospectus (after
initial filing of the Registration Statement), provide copies of such document
to counsel to the selling holders of Registrable Securities and to the managing
underwriters, if any, make the Company's executive officers and other
representatives available for discussion of such document and make such changes
in such document prior to the filing thereof as counsel for such selling holders
or underwriters may reasonably request.

<PAGE>

              The Company may require each seller of Registrable Securities
as to which any Registration is being effected to furnish to the Company such
information regarding the proposed distribution of such securities as the
Company may from time to time reasonably request in writing. Each holder of
Registrable Securities agrees by acquisition of such Registrable Securities
that, upon receipt of any notice from the Company of the happening of any event
of the kind described in Section 5(d)(xi), such holder shall forthwith
discontinue disposition of Registrable Securities until such holder's receipt of
the copies of the supplemented or amended prospectus contemplated by Section
5(d)(xi), or until it is advised in writing (the "Advice") by the Company that
the use of the Prospectus may be resumed, and has received copies of any
additional or supplemental filings that are incorporated by reference in the
Prospectus; and, if so directed by the Company, such holder shall deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in such seller's possession, of the Prospectus covering such Registrable
Securities current at the time of receipt of such notice. In the event the
Company gives any such notice, the time periods regarding the maintenance of the
effectiveness of any Registration Statement in Section 5(d)(ii) shall be
extended by the number of days during the period from and including the date of
the receipt of such notice pursuant to Section 5(d)(iii)(F) hereof to and
including the date when each seller of Registrable Securities covered by such
Registration Statement shall have received the copies of the supplemented or
amended prospectuses contemplated by Section 5(d)(xi) or the Advice.

     (e) INDEMNIFICATION.

              (i)   In the event of the Registration or qualification of any
Registrable Securities under the Securities Act or any other applicable
securities laws pursuant to the provisions of this Section 5, the Company agrees
to indemnify and hold harmless each Stockholder thereby offering such
Registrable Securities for sale (an "Indemnified Stockholder"), underwriter,
broker or dealer, if any, of such Registrable Securities, and each other person,
if any, who controls any such Indemnified Stockholder, underwriter, broker or
dealer within the meaning of the Securities Act or any other applicable
securities laws, from and against any and all losses, claims, damages, expenses
or liabilities (or actions in respect thereof), joint or several, to which such
Indemnified Stockholder, underwriter, broker or dealer or controlling person may
become subject under the Securities Act or any other applicable federal or state
securities laws or otherwise, insofar as such losses, claims, damages, expenses
or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of any material fact contained
in any Registration Statement under which such Registrable Securities were
registered or qualified under the Securities Act or any other applicable
securities laws, any preliminary prospectus or final prospectus relating to such
Registrable Securities, or any amendment or supplement thereto, or 

<PAGE>

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 not misleading, or any violation by the Company of any rule
or regulation under the Securities Act or any other applicable federal or state
securities laws applicable to the Company or relating to any action or inaction
required by the Company in connection with any such Registration or
qualification, and will reimburse each such Indemnified Stockholder,
underwriter, broker or dealer and each such controlling person for any legal or
other expenses reasonably incurred by such Indemnified Stockholder, underwriter,
broker or dealer or controlling person in connection with investigating or
defending any such loss, claim, damage, expense, liability or action; PROVIDED,
HOWEVER, that the Company will not be liable in any such case to the extent that
any such loss, claim, damage, expense or liability arises out of or is based
upon an untrue statement or omission contained in such Registration Statement,
such preliminary prospectus, such final prospectus or such amendment or
supplement thereto, made in reliance upon and in conformity with written
information furnished to the Company by such Indemnified Stockholder,
underwriter, broker, dealer or controlling person specifically and expressly for
use in the preparation thereof or by the failure of such Indemnified
Stockholder, underwriter, broker or dealer, or controlling person to deliver a
copy of the Registration Statement, such preliminary prospectus, such final
prospectus or such amendment or supplement thereto after the Company has
furnished such party with a sufficient number of copies of the same and such
party failed to deliver or otherwise provide a copy of the final prospectus to
the person asserting an untrue statement or omission or alleged untrue statement
or omission at or prior to the written confirmation of the sale of securities to
such person, if such statement or omission was in fact corrected in such final
prospectus.

              (ii)  In the case of an underwritten offering in which the
Registration Statement covers Registrable Securities, the Company agrees to
enter into an underwriting agreement in customary form and substance with such
underwriters and to indemnify the underwriters, their officers and directors, if
any, and each person, if any, who controls such underwriters within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act, to the
same extent as provided in the preceding paragraph with respect to the
indemnification of the holders of Registrable Securities; PROVIDED, HOWEVER, the
Company shall not be required to indemnify any such underwriter, or any officer
or director of such underwriter or any person who controls such underwriter
within the meaning of Section 15 of the Securities Act and Section 20 of the
Exchange Act, to the extent that the loss, claim, damage, expense or liability
(or actions in respect thereof) for which indemnification is sought results from
such underwriter's failure to deliver or otherwise provide a copy of the final
prospectus to the person asserting an untrue statement or omission or alleged
untrue statement or omission at or prior to the written confirmation of the sale
of securities to such person, if such statement or omission was in fact
corrected in such final prospectus.

<PAGE>

              (iii) In the event of the Registration or qualification of any
Registrable Securities of the Stockholders under the Securities Act or any other
applicable federal or state securities laws for sale pursuant to the provisions
hereof, each Indemnified Stockholder agrees severally, and not jointly, to
indemnify and hold harmless the Company, each person who controls the Company
within the meaning of the Securities Act, and each officer and director of the
Company from and against any losses, claims, damages, expenses or liabilities
(or actions in respect thereof), joint or several, to which the Company, such
controlling person or any such officer or director may become subject under the
Securities Act or any other applicable securities laws or otherwise, insofar as
such losses, claims, damages, expenses or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement of any material
fact contained in any Registration Statement under which such Registrable
Securities were registered or qualified under the Securities Act or any other
applicable securities laws, any preliminary prospectus or final prospectus
relating to such Registrable Securities, or any amendment or supplement thereto,
or arise out of or are based upon an untrue statement therein or the omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, which untrue statement or omission was
made therein in reliance upon and in conformity with written information
furnished to the Company by such Indemnified Stockholder specifically and
expressly for use in connection with the preparation thereof, and will reimburse
the Company, such controlling person and each such officer or director for any
legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, expense, liability or
action; PROVIDED, HOWEVER, an Indemnified Stockholder's liability under this
Section 5(e)(iii) shall not exceed the net proceeds received by such Indemnified
Stockholder with respect to the sale of any Registrable Securities.

              (iv)  In the case of an underwritten offering of Registrable
Securities, each holder of a Registrable Security included in a Registration
Statement shall agree to enter into an underwriting agreement in customary form
and substance with such underwriters, and to indemnify such underwriters, their
officers and directors, if any, and each person, if any, who controls such
underwriters within the meaning of Section 15 of the Securities Act and Section
20 of the Exchange Act, to the same extent as provided in the preceding
paragraph with respect to indemnification by such holder of the Company, but
subject to the same limitation as provided in Section 5(e)(ii) with respect to
indemnification by the Company of such underwriters, officers, directors and
control persons.

              (v)   Promptly after receipt by a person entitled to
indemnification under this Section 5(e) (an "Indemnified Party") of notice of
the commencement of any action or claim relating to any Registration Statement
filed under this Section 5 as to which indemnity may be sought hereunder, such
Indemnified Party will, if a claim for indemnification hereunder in respect
thereof is to be made against any other party 

<PAGE>

hereto (an "Indemnifying Party"), give written notice to each such Indemnifying
Party of the commencement of such action or claim, but the omission to so notify
each such Indemnifying Party will not relieve any such Indemnifying Party from
any liability which it may have to any Indemnified Party otherwise than pursuant
to the provisions of this Section 5(e) and shall also not relieve any such
Indemnifying Party of its obligations under this Section 5(e) except to the
extent that any such Indemnifying Party is actually prejudiced thereby. In case
any such action is brought against an Indemnified Party, and such Indemnified
Party notifies an Indemnifying Party of the commencement thereof, such
Indemnifying Party will be entitled (at its own expense) to participate in and,
to the extent that it may wish, jointly with any other Indemnifying Party
similarly notified, to assume the defense, with counsel reasonably satisfactory
to such Indemnified Party, of such action and/or to settle such action and,
after notice from the Indemnifying Party to such Indemnified Party of its
election so to assume the defense thereof, the Indemnifying Party will not be
liable to such Indemnified Party for any legal or other expenses subsequently
incurred by such Indemnified Party in connection with the defense thereof, other
than the reasonable cost of investigation; PROVIDED, HOWEVER, that no
Indemnifying Party shall consent to the entry of any judgment or enter into any
settlement agreement without the prior written consent of the Indemnified Party
unless such Indemnified Party is fully released and discharged from any such
liability, and no Indemnified Party shall consent to the entry of any judgment
or enter into any settlement of any such action the defense of which has been
assumed by an Indemnifying Party without the consent of each Indemnifying Party.
Notwithstanding the foregoing, the Indemnified Party shall have the right to
employ its own counsel in any such case, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Party unless (a) the
employment of such counsel shall have been authorized in writing by the
Indemnifying Party in connection with the defense of such suit, action, claim or
proceeding; (b) the Indemnifying Party shall not have employed counsel
(reasonably satisfactory to the Indemnified Party) to take charge of the defense
of such action, suit, claim or proceeding; or (c) such Indemnified Party shall
have reasonably concluded, based upon the advice of counsel, that there may be
defenses available to it which are different from or additional to those
available to the Indemnifying Party which, if the Indemnifying Party and the
Indemnified Party were to be represented by the same counsel, could result in a
conflict of interest for such counsel or materially prejudice the prosecution of
the defenses available to such Indemnified Party. If any of the events specified
in clause (a), (b) or (c) of the preceding sentence shall have occurred or shall
otherwise be applicable, then the fees and expenses of one counsel or firm of
counsel selected by a majority in interest of the Indemnified Parties (and
reasonably acceptable to the Indemnifying Party) shall be borne by the
Indemnifying Party. If, in any such case, the Indemnified Party employs separate
counsel, the Indemnifying Party shall not have the right to direct the defense
of such action, suit, claim or proceeding on behalf of the Indemnified Party and
the Indemnified Party shall assume such defense and/or settle such action;
PROVIDED, HOWEVER, that an Indemnifying Party shall not be liable for the
settlement of any action,

<PAGE>

suit, claim or proceeding effected without its prior written consent, which
consent shall not be unreasonably withheld.

              The provisions of this Section 5(e) shall be in addition to
any liability which any party may have to any other party and shall survive any
termination of this Agreement.

              (f) CONTRIBUTION. If for any reason the indemnification provided 
for in Section 5(e)(i) or 5(e)(iii) is unavailable to an Indemnified Party as
contemplated therein, then the Indemnifying Party, in lieu of indemnification
shall contribute to the amount paid or payable by the Indemnified Party as a
result of such loss, claim, damage, expense or liability (or action in respect
thereof) in such proportion as is appropriate to reflect not only the relative
benefits received by the Indemnified Party and the Indemnifying Party, but also
the relative fault of the Indemnified Party and the Indemnifying Party, as well
as any other relevant equitable considerations, PROVIDED that no Stockholder
shall be required to contribute in an amount greater than the net proceeds
received by such Stockholder with respect to the sale of any Registrable
Securities less all amounts already contributed by such Stockholder with respect
to such claims, including amounts paid for any legal or other fees or expenses
incurred by such Stockholder. No person guilty of a 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 any such fraudulent
misrepresentation. The relative fault of such Indemnifying Party and Indemnified
Party shall be determined by reference to, among other things, whether any
action in question, including any untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact, has been
made by, or relates to information supplied by, such Indemnifying Party or
Indemnified Party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action.

              (g) REGISTRATION EXPENSES. Except as hereinafter provided, all
expenses incident to the Company's performance of or compliance with this
Section 5 will be borne by the Company, including, without limitation, all
Registration and filing fees under the Securities Act and the Exchange Act, the
fees and expenses of the counsel and accountants for the Company (including the
expenses of any "cold comfort" letters and special audits required by or
incident to the performance of such persons), all other costs and expenses of
the Company incident to the preparation, printing and filing under the
Securities Act of the Registration Statement (and all amendments and supplements
thereto), and furnishing copies thereof and of the Prospectus included therein,
all out-of-pocket expenses of underwriters customarily paid for by issuers to
the extent provided for in any underwriting agreement, the costs and expenses
incurred by the Company in connection with the qualification of the Registrable
Securities under the state securities or "blue sky" laws of various
jurisdictions, the costs and expenses associated with filings required to be
made with the NASD, the costs and expenses of 

<PAGE>

listing the Registrable Securities for trading on a national securities exchange
or authorizing them for trading on NASDAQ and all other costs and expenses
incurred by the Company in connection with any Registration hereunder. In
addition, the Company shall pay or reimburse the sellers of Registrable
Securities the reasonable fees and expenses of one law firm to such sellers
incurred in connection with a registration (collectively, with the expenses
referred to in the immediately preceding sentence, the "Registration Expenses").
Except as provided in the immediately preceding sentence, each Stockholder shall
bear the costs and expenses of any underwriters' discounts and commissions,
brokerage fees or transfer taxes relating to the Registrable Securities sold by
such Stockholder and the fees and expenses of any attorneys, accountants or
other representatives retained by the Stockholder.

              (h) PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Stockholder
may participate in any underwritten Registration hereunder unless such
Stockholder (i) agrees to sell its Registrable Securities on the basis provided
in any customary and reasonable underwriting arrangements approved by the
persons entitled hereunder to select the underwriter, and (ii) accurately
completes in a timely manner and executes all questionnaires, powers of
attorney, underwriting agreements, indemnities and other documents customarily
required under the terms of such underwriting arrangements.

              (i) HOLDBACK AGREEMENTS.

                    (i) Each holder of Registrable Securities whose securities 
are included in a Registration Statement agrees not to effect any sale, transfer
or other disposition of Company Stock or any securities convertible into Company
Stock or other interest in the Company, including through any hedging or
derivative transaction or to effect any distribution of the issue being
registered or a similar security of the Company, or any securities convertible
into or exchangeable or exercisable for such securities, including a sale
pursuant to Rule 144 or Rule 144A under the Securities Act, during the fifteen
(15) days prior to, and during the one hundred eighty (180)-day period (or such
longer period as reasonably requested by the managing underwriter or
underwriters in the case of an underwritten public offering) beginning on, the
effective date of such Registration Statement (except as part of such
Registration), if and to the extent requested by the managing underwriter or
underwriters in an underwritten public offering.

                    (ii) The Company agrees not to effect any public sale or 
distribution of the issue being registered or a similar security of the Company,
or any securities convertible into or exchangeable or exercisable for such
securities (other than any such sale or distribution of such securities in
connection with any merger or consolidation by the Company or any Subsidiary or
the acquisition by the Company or any Subsidiary of the capital stock or
substantially all of the assets of any other Person), during the fifteen (15)
days prior to, and during the ninety (90)-day period beginning on, the effective
date of each Demand Registration.

<PAGE>

              (j) PUBLIC INFORMATION REPORTING. (i) The Company hereby covenants
and agrees to and with the Stockholders that at all times following the IPO Date
it shall provide and file such financial and other information concerning the
Company as may from time to time be required by the Commission and any other
governmental authority having jurisdiction, so as to comply with all reporting
requirements under the Exchange Act, and shall, upon request, state in writing
that it has complied with all such requirements, and further agrees that, for so
long as (following the IPO Date) the Company is not subject to Section 13 or
15(d) of the Exchange Act, the Company shall comply in all respects with
paragraph (c)(2) of Rule 144.

                    (ii) If the Company shall have filed a registration 
statement pursuant to the requirements of Section 12 of the Exchange Act or a
registration statement pursuant to the requirements of the Securities Act, the
Company covenants that it will file the reports required to be filed by it under
the Securities Act and the Exchange Act and the rules and regulations adopted by
the Commission thereunder (or, if the Company is not required to file such
reports, it will, upon the request of any holder of Registrable Securities, make
publicly available other information), and it will take such further action as
any holder of Registrable Securities may reasonably request, all to the extent
required from time to time to enable such holder to sell shares of Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by (i) Rule 144 under the Securities Act, as such
Rule may be amended from time to time, or (ii) any similar rule or regulation
hereafter adopted by the Commission. Upon the request of any holder of
Registrable Securities, the Company will deliver to such holder a written
statement as to whether it has complied with such requirements. Upon the request
of a holder of Registrable Securities, the Company covenants and agrees to
provide the information required by Rule 144A(d)(4) under the Securities Act.


                                   ARTICLE 6.

encumber or otherwise dispose of any shares of capital stock of any of the
Company's Subsidiaries to any Person other than the Company and its direct or
indirect wholly owned Subsidiaries, except for a pledge of any such shares in
connection with the incurrence of indebtedness.

<PAGE>

     6.2      AMENDMENTS OF THE RESTATED CERTIFICATE AND BY-LAWS. Prior to the
IPO Date, the Company shall not authorize or adopt any amendment, modification
or repeal of any provision of the Restated Certificate or the Restated By-Laws,
unless such amendment is consistent with the terms of this Agreement, and the
Restated Certificate and has been approved by a majority of directors of the
Board of Directors.

     6.3      CONFIDENTIALITY.

              (a) Each party shall, and shall cause each of its Affiliates, and
its and their respective stockholders, members, managers, directors, officers, 
employees and agents (collectively, "Representatives") to, keep secret and 
retain in strictest confidence any and all information relating to the Company 
or any other party that is either a trade secret or material, non-public 
information or is designated in writing by the party providing such information
or the Company as confidential (other than, in each case, such information as is
otherwise or becomes publicly available (other than in violation of this
Agreement or other applicable confidentiality agreements among the parties), or
has been or is independently developed or obtained from a person in a manner not
in violation of this Agreement or, to its knowledge, any other confidentiality
agreement) ("Confidential Information") and shall not disclose such information,
and shall cause its Representatives not to disclose such information, to anyone
except such Affiliates, Representatives or any other Person that agrees in
writing to keep in confidence all such information in accordance with the terms
of this Section 6.3. Each party agrees to use such information received from
another party or the Company only in connection with its ownership interest in
the Company but not for any other purpose. All such information furnished
pursuant to this Agreement shall be returned promptly to the party to whom it
belongs upon request by such party.

              (b) To the fullest extent permitted by law, if a party or any of
its Affiliates or Representatives breaches, or threatens to commit a breach of,
this Section 6.3, the party whose Confidential Information shall be disclosed,
or threatened to be disclosed, shall have the right and remedy to have this
Section 6.3 specifically enforced by any court having jurisdiction, it being
acknowledged and agreed that money damages will not provide an adequate remedy
to such party. Nothing in this Section 6.3 shall be construed to limit the right
of any party to collect money damages in the event of breach of this Section
6.3.

              (c) Anything else in this Agreement notwithstanding, each party
shall have the right to disclose any information, including Confidential
Information of the other party or such other party's Affiliates, in any filing
with any regulatory agency, court or other authority or any disclosure to a
trustee of public debt of a party to the extent that the disclosing party
determines in good faith that it is required by Law, regulation or the terms of
such debt to do so; PROVIDED, HOWEVER, that any such disclosure shall be as
limited in scope as possible and shall be made only after giving

<PAGE>

the other party as much notice as practicable of such required disclosure and an
opportunity to contest such disclosure if possible.

     6.4      SALE OF LOGIX COMMUNICATIONS STOCK. If JWC or AT&T proposes to 
sell any number of shares of Logix Communications Common Stock which sale would
result in a reduction in the ownership interest of JWC or AT&T in Logix
Communications below 35% of the JWC or AT&T Logix Communications ownership
interest, as the case may be, on the Logix Communications Spin-Off (calculated
with reference only to shares of Logix Communications issued with respect to the
Class D Preferred Stock (or any Class A Common Stock or other capital stock
issued with respect thereto other than the JWC Common Stock held as of the
Amendment and Restatement Date), JWC or AT&T, as the case may be, shall give 10
Business Days' written notice thereof to the Company (the "Section 6.4 Notice
Period") and during such Section 6.4 Notice Period the Company may elect to
purchase such Logix Communications Common Stock at a price which is the Market
Price thereof. In the event the Company elects to purchase such Logix
Communications Common Stock, it shall have 30 days (or such longer period as may
be necessary under the Appraisal Procedure) from the date of receipt of the
written notice from JWC or AT&T, as the case may be, in which to purchase such
Logix Communications Common Stock. This purchase right shall terminate upon the
earliest to occur of (i) the consummation by Logix Communication of an initial
public offering of its common stock with aggregate gross proceeds of at least
$50 million, (ii) December 23, 2003, (iii) the exercise by the Stockholders of
the call right pursuant to the terms of Article 11, or (iv) the expiration of
the call right pursuant to the terms of Article 11.

     6.5      CLASS PROTECTION. The Company shall not, without first obtaining
consent or approval of the holders of at least a majority of the holders of each
affected class of Company Stock (including each of JWC and AT&T, if they are
holders of such class of Company Stock), voting as a separate class: (i)
adversely amend or alter any preferences, rights or powers of any such class of
Company Stock; or (ii) redeem, repurchase or pay any dividends on any junior
stock or parity stock, except for repurchases of stock or stock options issued
to management, employees or consultants which do not exceed $500,000 in any
fiscal year of the Company or in any event $1,500,000 in the aggregate.

     6.6      NEW SECURITIES. (a) Subject to the terms of the Class D Preferred
Stock Certificate of Designation, any Common Stock (other than JWC Common Stock)
and any Logix Communications Common Stock issued to holders of Class D Preferred
Stock shall receive anti-dilution protection, as determined reasonably in good
faith by the Board of Directors to protect the holders thereof in connection
with (i) dilution from the issuance or the exercise of warrants issued in
connection with the Sygnet Acquisition, (ii) any dilution relating to options
then issued or committed as of the Closing Date under the New Company Stock
Option Plan, (iii) any dilution resulting

<PAGE>

from the issuance of options with respect to an aggregate maximum of 5% of the
Logix Communications Stock, (iv) the redemption of all shares of Class B
Preferred Stock and Class C Preferred Stock pursuant to the terms of the
Investment and Transaction Agreement and (v) dilution relating to the conversion
of the Class G Preferred Stock into Class H Preferred Stock and Class A Common
Stock.

     (b) Without the prior written consent of JWC (except where any such
issuance would not have a dilutive effect on JWC's Beneficial Ownership interest
in either the Common Stock (including Common Stock issuable upon conversion of
Class D Preferred Stock) or the Logix Communications Common Stock, or both) (as

the original purchase price of the Class D Preferred Stock, plus (y) one times
such original purchase price multiplied by a fraction, the numerator of which
is the number of quarterly periods elapsed after such twenty-fourth month
anniversary of their date of issuance (measured from the commencement of such
twenty-fifth month anniversary), up to 12 quarterly periods, and the denominator
of which is 12. Schedule V set forth an illustrative example for this Article
11, PROVIDED, HOWEVER, that in the case of any conflict between such
illustration and this Article 11, this Article 11 shall govern. In the event of
a sale or sales by JWC or AT&T of any portion of the final 35% of their
respective investment in Logix Communications Common Stock as of the date of the
Logix Communications Spin-off

<PAGE>

(calculated with reference only to shares of Logix Communications issued with
respect to the Class D Preferred Stock (or any Class A Common Stock or other
capital stock issued in respect thereto other than the JWC Common Stock) held
as of the Amendment and Restatement Date), then the Clawback Exercise Price
with respect to such selling stockholder's Company Stock shall, if applicable,
be reduced by the aggregate amount of the net proceeds of such sales, PROVIDED
that proceeds received by JWC or AT&T, as the case may be, from the exercise by
the Company of its purchase right under Section 6.4 shall not so reduce the
Clawback Exercise Price.

              This call right may only be exercised in respect of the entire
part of the Equity Investor Package subject thereto and the initial
determination whether to exercise this call right will be made by the Dobson
Partnership on behalf of all the Stockholders, PROVIDED that after such
determination, each Stockholder will make its own determination whether to
consummate the call right. This call right shall terminate upon the earlier of
the occurrence of (A) the IPO Date, (B) the fifth anniversary of issuance of
the Class D Preferred Stock, (C) a Change of Control or (D) the exercise in
full of this call right, PROVIDED, that this call right may be exercised in
connection and concurrently with an IPO and the proceeds resulting from such
public offering may be applied by the Company in payment of the Clawback
Exercise Price. Except pursuant to Sections 4.2, 4.5 and Article 12 of
this Agreement, each Cash Equity Investor will agree not to sell or transfer the
securities included in their Equity Investor Package (excluding Logix
Communications Common Stock) until the call right expires if, after such sale or
transfer, such Cash Equity Investor would hold less than 35% of (x) the Class D
Preferred Stock it held as of the Amendment and Restatement Date, (y) any class
of securities issued in respect of the Class D Preferred Stock (other than Logix
Communication Stock), or (z) each class of securities included in the Equity
Investor Package (excluding Logix Communications Common Stock).


                                   ARTICLE 12.

                                   PUT RIGHTS

     12.1     CLASS D AND CLASS E PREFERRED STOCK PUT RIGHT. At any time after
the earliest to occur of (i) December 23, 2005, (ii) a Change of Control, or
(iii) the consummation of an IPO, each of JWC and AT&T shall have the right to
sell all of the Class D Preferred Stock or Class E Preferred Stock held by such
party to the Company (the "Preferred Stock Put Right") and the Company shall
have the obligation to purchase the shares as to which the Preferred Stock Put
Rights are exercised. Subject to Section 12.3, the Company shall, within 120
days of the exercise by JWC or AT&T of its Preferred Stock Put Right (or
immediately in the case of a Change of Control) pay (A) in the case of a put of
Class D Preferred Stock a cash amount per share equal to the then current
Liquidation Preference thereon plus the number of shares of Class A

<PAGE>

Common Stock that the holder of such Class D Preferred Stock would have
received upon conversion immediately prior to such put and (B) in the case of
Class E Preferred Stock a cash amount per share held by such Stockholder equal
to its Liquidation Preference. Notwithstanding the foregoing, the Company shall
not redeem any shares pursuant to this Section 12.1 unless such redemption is
made pro-rata amongst all the parties who have exercised their Preferred Stock
Put Rights pursuant to this Section 12.1 on the date of any redemption. The
closing of any redemption pursuant to this Section 12.1 shall take place at the
Company's offices or at such reasonable other location as the Company may notify
the other parties in writing. Notwithstanding anything in this section to the
contrary, neither AT&T nor JWC shall be bound to transfer its Preferred Stock
upon the exercise by the other party of its Preferred Stock Put Right and in the
event that AT&T or JWC elects not to so transfer its Preferred Stock, such party
shall retain the right to exercise the Preferred Stock Put Right with respect to
its Preferred Stock. In the event that AT&T or JWC exercises its Preferred Stock
Put Right and the other party does not elect to exercise its Preferred Stock Put
Right within 20 days of such exercise, then such other party may not exercise
its Preferred Stock Put Right until 120 days following such initial exercise.

     12.2     CONFLICT EVENTS. (a) (i) Either AT&T or the Company may give
notice (a "Conflict Notice") to the other parties hereto, if it becomes aware of
the existence of a Conflict or enters into an agreement that would give rise to
a Conflict, or reasonably believes that a Conflict is likely to occur as a
result of pending transactions or other proposed actions, which notice shall
describe the Conflict in reasonable detail.

     (ii)     In the event that a party gives a Conflict Notice, the Company and
AT&T shall use their commercially reasonable best efforts to determine whether a
Conflict exists (or will exist after giving effect to pending transactions or
other proposed actions) and, if so, will use their commercially reasonable
efforts to agree in principle, within 60 days of receipt of such Conflict Notice
by the recipient thereof, as to a course of action (including a framework of
time within which to execute binding definitive agreements or to consummate and
complete the transaction contemplated by such agreements) to cure such Conflict
to the reasonable satisfaction of each of the Company and AT&T (an "Agreement in
Principle"). In the event the parties fail to (x) agree in principle as to such
course of action within such 60-day period, or (y) execute such binding
definitive agreements or consummate and complete the transactions contemplated
by such binding definitive agreements, in each case in accordance with the
Agreement in Principle then the provisions of Section 12.2(b) shall be
applicable.

     (b)      In the event that a Conflict Notice is given with respect to
either a Competitive Conflict or a Regulatory Conflict, and the provisions of
Section 12.2(b) are applicable pursuant to Section 12.2(a), then:

              (i)   In the case of the occurrence (without the prior written
consent of

<PAGE>

 AT&T) of a Company Competitive Conflict or a Company Regulatory
Conflict, AT&T shall have the right to send a notice (a "Conflict Put Notice")
to the other parties hereto, which notice triggers the terms of Section 12.2(c).

              (ii)  In the case of the occurrence (without the prior written
consent of the Company) of an AT&T Competitive Conflict or an AT&T Regulatory
Conflict, the Company shall have the right to send a notice (a "Conflict
Non-Voting Notice") to AT&T, which notice triggers the terms of Section 12.2(d).

              (iii) In the case of a Conflict resulting solely from a Change
of Law, then the parties agree to address such Conflict and the remedies
appropriate to resolve such conflict in good faith and a reasonable manner, at
the time such Conflict occurs.

     (c)      If AT&T sends a Conflict Put Notice in accordance with
Section 12.2(b)(i), the Company shall have the obligation to purchase all of the
shares of Company Stock (other than any stock of Logix Communications from and
after the Logix Communications Spin-Off) then held by AT&T or its Affiliates.
Subject to Section 12.3, the purchase price therefor shall be payable in cash
and shall equal: (i) in the case of Class D Preferred Stock, an amount per share
equal to the then-current Liquidation Preference thereof, plus the Market Price
of the number of shares of Class A Common Stock that would have been received
upon conversion thereof on the date of the purchase; (ii) in the case of Class E
Preferred Stock, an amount per share equal to the then current Liquidation
Preference thereof; and (iii) in the case of any other class of Common Stock, an
amount per share equal to the Market Price thereof. The closing of any purchase
pursuant to this Section 12.2(c) shall take place within 120 business days after
the date of the Conflict Put Notice (or such longer period as may be necessary
under the Appraisal Procedure) at the Company's offices or such other location
or time as to which AT&T and the Company agree.

         (d) If the Company sends a Conflict Non-Voting Notice to AT&T in
accordance with Section 12.2(b)(ii) or AT&T sends a Conflict Non-Voting Notice,
in its sole discretion at any time, then (i) AT&T shall cause the director
designated by it pursuant to Section 3.1(a)(ii) to resign (or the parties shall
cause the removal of such director) from the Company's Board of Directors,
within 10 business days of the date of the Conflict Non-Voting Notice and AT&T
will relinquish its director designation right in accordance with Section
3.1(b), (ii) the parties shall negotiate in good faith, and promptly implement,
steps appropriate to eliminate the voting rights of any Company Stock then owned
by AT&T or its Affiliates (E.G., by AT&T exchanging its shares of Class D
Preferred Stock for an equal number of shares of a new class of preferred stock
having no voting rights and convertible into common stock having no voting
rights, except in each case to the extent required by law, or AT&T agreeing to
vote all of its shares in the same proportion as all other shares of Company
Stock are voted) and, to the extent necessary to eliminate a Regulatory
Conflict, to eliminate any

<PAGE>

consent, approval, veto or similar rights AT&T enjoys pursuant to the terms of
this Agreement and (iii) the parties will otherwise proceed reasonably and in
good faith to resolve the circumstances giving rise to the Conflict Non-Voting
Notice; PROVIDED that and except as set forth in this Agreement no party shall
be required to agree to any change, modification or supplement that adversely
affects such party in any material respect, and nothing in this Agreement shall
be construed to require any party to agree to divest or hold separate any of
its assets or otherwise take or commit to take any action that limits its
freedom of action in any material respect with respect to any of its
businesses, product lines or assets. Notwithstanding the foregoing, if a
Conflict Non-Voting Notice shall be sent, and AT&T shall subsequently Transfer
any Company Stock, then the voting rights of such Company Stock to be
transferred shall be immediately reinstated and the transferee shall be
transferred Company Stock with full voting rights. The parties hereby
acknowledge and agree that any procedures effected pursuant to this Section
12.2(d) shall remain in effect until the Conflict giving rise to the Conflict
Non-Voting Notice no longer exists.

     (e)      The parties agree that Section 12.2(b) will be inapplicable to any
Regulatory Conflict existing on the date hereof, and that the parties will
proceed in good faith to resolve or cure such Conflicts; AT&T further agrees
that it will not exercise its right to select a director pursuant to Section
3.1(a)(ii) until each of the Company and AT&T are satisfied that no Regulatory
Conflict exists as of the date hereof or any such Regulatory Conflict has been
cured or the appropriate Governmental Authorities have furnished a waiver with
respect thereto.

     (f)      Notwithstanding anything in this Agreement to the contrary
(including, without limitation, Section 12.2(a)) AT&T shall have 30 days from
the date of receipt of a Conflict Notice within which to either confirm or deny
that a Conflict may exist upon consummation of the transactions referred to in
the Conflict Notice. If AT&T either fails to respond to such Conflict Notice or
informs the Company that no Conflict may exist upon consummation of the
transactions referred to in the Conflict Notice and the parties subsequently
learn that a Conflict did in fact arise, AT&T shall be precluded from asserting
its rights under Section 12.2(b)(i) in respect of such Conflict.

     (g)      Nothing in this Agreement shall be construed to require AT&T or
any of its Subsidiaries to take any action, including without limitation
divesting any of their respective properties or other assets, other than in
respect of shares of Company Stock Beneficially Owned by them or their rights
under this Agreement or other rights arising from ownership of such Company
Stock or agreements with the Company.

     (h)      The Company may deliver a notice to AT&T requesting that AT&T
confirm or deny that a Conflict exists, or may exist upon completion of a
transaction or transactions that have been publicly announced by AT&T, (i) at
any time the Company reasonably believes that AT&T has engaged in a transaction
or transactions that may

<PAGE>

create a Conflict, and (ii) once during any calendar year (without regard to any
notices given pursuant to clause (i) of this sentence). Such notice shall
include a list of the Licenses held by the Company and its Subsidiaries. AT&T
shall respond to such notice within 15 days stating whether or not it is aware,
to the best of its knowledge, that a Conflict exists. Any such notice or
information given by AT&T will be deemed to be Confidential Information subject
to Section 6.3 of this Agreement.

     12.3     PAYMENT; RESTRICTIONS ON PAYMENT. Upon the surrender of the
certificate or certificates evidencing the shares of stock to be repurchased by
the Company pursuant to the Put Rights in Section 12.1 or 12.2(c), the
repurchase price in respect of such shares shall be paid to the order of the
Person whose name appears on such certificate or certificates in cash by wire
transfer of immediately available funds, PROVIDED, that if there is no Available
Cash under the Financing Agreements and consistent with the limitations set
forth in Section 12.4, the Company shall arrange additional credit facilities or
borrowing availability to obtain cash to meet its obligations upon the exercise
of the Put Right. If the Company cannot, within the time periods stated in
Sections 12.1 and 12.2(c), obtain cash to meet its obligations upon the exercise
of the Put Right, then the Company shall issue to the Cash Equity Investor
exercising the Put Right a Subordinated Put Note, dated as of the date of
exercise of the Put Right, which shall rank senior to each class of Preferred
Stock existing on the date hereof other than the Senior PIK Preferred Stock and
the Sygnet PIK Preferred Stock. Each surrendered certificate shall be canceled
and/or retired. In the event that a Cash Equity Investor receives a Subordinated
Put Note, such Cash Equity Investors shall be entitled to all of the rights of
the holders of Class D Preferred Stock hereunder as if such Cash Equity
Investors were holders of Class D Preferred Stock until the Subordinated Put
Notes are paid in full. In the event that Subordinated Put Notes are issued, all
such Subordinated Put Notes will rank pari passu and shall share pro rata in any
Available Cash, PROVIDED, HOWEVER, that in the event that any Subordinated Put
Note shall have matured, such Subordinated Put Note shall rank senior to any
Subordinated Put Note which has not yet matured.

     12.4     RESTRICTIONS ON PAYMENTS BY THE COMPANY. Notwithstanding anything
to the contrary contained in this Agreement, the payment of cash upon exercise
of a Put Right and pursuant to any Subordinated Put Notes pursuant to this
Article shall be subject to (i) applicable restrictions contained in any
applicable law, including the availability of adequate capital and surplus for
corporate law purposes and (ii) restrictions contained in the Financing
Agreements (other than the Class F Preferred Stock Documents) each as refinanced
or amended and in effect from time to time in accordance with Section 12.6, and
restrictions contained in any Senior Indebtedness. If any such restrictions or
unavailability prohibit the repurchase of Securities or other capital stock of
the Company hereunder which the Company is otherwise entitled or required to
make, the Company shall make such repurchases as soon as it is permitted to do
so under such restrictions.

<PAGE>

     12.5     PAYMENT OF CASH.  Notwithstanding anything else in this
Article 12 to the contrary (including Sections 12.3 and 12.4), in the event of a
Change of Control, and in each case in which Stockholders receive cash, cash
equivalents or marketable securities for the sale or transfer of the Company's
Voting Securities, then the holders of the Class D Preferred Stock and Class E
Preferred Stock shall be paid cash upon exercise of a Put Right and shall not be
issued Subordinated Put Notes in lieu of cash.

     12.6     FINANCING AGREEMENTS; INDEBTEDNESS. The Class D Preferred Stock
and Class E Preferred Stock, including any redemptions (except as set forth
below), puts and calls and any Subordinated Put Notes issued pursuant to such
puts, are subject to the terms and restrictions contained in the Financing
Agreements. The Company will be permitted to refinance or replace (whether or
not with new lenders) any Financing Agreement and/or incur additional
indebtedness in connection with acquisitions and capital projects at any time
prior to the issuance of any Subordinated Put Note issued in connection with a
Put Right, so long as the Company has used commercially reasonable efforts to
negotiate standard covenant flexibility with regard to permitting payment of the
Put Right and such refinancing, replacement or additional indebtedness (i) is
not more restrictive with respect to the Preferred Stock than the Financing
Agreements and (ii) specifically permits the payment of amounts owing by the
Company upon exercise of such Preferred Stock Put Right or to the holder of any
such Subordinated Put Note if after giving pro forma effect to any such payment,
the Consolidated Leverage Ratio would be less than 8 to 1. Following the
issuance of any Subordinated Put Note issued in connection with a Put Right, the
Company may not undertake any refinancing or replacement (but shall be free to
obtain waivers from the holders of existing indebtedness) or incur additional
financing indebtedness in excess of $1,000,000, in the aggregate, without the
prior written consent of the holder of such Subordinated Put Note. Nothing
herein shall limit the right of the Company to incur indebtedness in order to
discharge all amounts owing under any such outstanding Subordinated Put Notes.
No refinancing replacement or additional financing indebtedness shall adversely
affect, and shall be expressly subordinate to, the redemption rights of the
Class D Preferred Stock and Class E Preferred Stock set forth in the
Certificates of Designation of the Class D Preferred Stock and Class E Preferred
Stock. The Cash Equity Investors shall deliver acknowledgments of the foregoing
to the Company's creditors under the Financing Agreements upon the request of
the Company.


                                   ARTICLE 13.

                               COMPANY CALL RIGHT

     13.1     COMPANY RIGHT TO CALL AGAINST CASH EQUITY INVESTORS. On or
immediately prior to an IPO, the Company or its assignees shall have the right
to purchase on a pro rata basis from the holders thereof all or any portion of
the outstanding shares of Class

<PAGE>

D Preferred Stock held by a Cash Equity Investor and upon the exercise of such
right, each Cash Equity Investor shall have the obligation to sell such shares
of Class D Preferred Stock held by such Cash Equity Investor to the Company. 
The call purchase price for each share of Class D Preferred Stock shall be the
Liquidation Preference thereof plus the number of shares of Class A Common
Stock that would have been received by the holder of such Class D Preferred
Stock had such Class D Preferred Stock been converted immediately prior to the
exercise of the call. Notwithstanding anything herein to the contrary, a holder
of Class D Preferred Stock may upon receiving a Call Notice (as defined below)
elect to convert his Class D Preferred Stock into Class E Preferred Stock and
Class A Common Stock, in which event the Company's right pursuant to this
Article 13 will apply to such Class E Preferred Stock.  The call purchase price
of any such Class E Preferred Stock shall be the Liquidation Preference thereof.

     13.2     PROCEDURE. The Company may exercise the Call Rights by providing
to the Cash Equity Investors a written notice (a "Call Notice") that the Company
will repurchase the shares of Company Stock described in Section 13.1. The
Company shall within thirty (30) days after the determination of the relevant
call price, and the notification of the Cash Equity Investors and in any event
no later than the receipt by the Company of the proceeds of the IPO, redeem the
shares held by the Stockholders to whom the Company provided a Call Notice by
paying to such Stockholders an amount for each share held by such Stockholder
equal to the relevant call price by wire transfer of immediately available
funds. The closing of the repurchase of the shares pursuant to this Article 13
shall take place at the office of the Company, or at such other reasonable
location, as it shall notify the relevant party to whom the Call Notice was
sent.

     13.3     PAYMENT. Upon the surrender of the certificate or certificates
evidencing the shares of Class D Preferred Stock or Class E Preferred Stock to
be repurchased by the Company pursuant to this Article 13, the applicable call
price in respect of such shares shall be paid by wire transfer of immediately
available funds to the order of the Person whose name appears on such
certificate or certificates in cash in immediately available funds (which shall
include any accrued and unpaid dividends to the date of repurchase of such
shares of Class D Preferred Stock or Class E Preferred Stock). Each surrendered
certificate evidencing the shares of Class D Preferred Stock or Class E
Preferred Stock being repurchased shall be canceled and/or retired.


                                   ARTICLE 14.

                                  MISCELLANEOUS

     14.1     JWC GROUP STOCKHOLDER REPRESENTATIVE. (a) Each JWC Group

<PAGE>

Stockholder hereby designates and irrevocably appoints Dana L. Schmaltz, as his
attorney-in-fact with full power of substitution (the "JWC Group Stockholder
Representative"), to serve as the representative of each such JWC Group
Stockholder to (i) perform all such acts as are required, authorized or
contemplated by this Agreement to be performed by such JWC Group Stockholder
(other than AT&T) and (ii) exercise such rights, power and authority as are
incidental to this Agreement and hereby acknowledges that the JWC Group
Stockholder Representative shall be the only person authorized to take any
action so required, authorized or contemplated by this Agreement by each such
person. Any such actions taken, exercises of rights, power or authority and any
decision or determination made by the JWC Group Stockholder Representative
consistent therewith, shall be absolutely and irrevocably binding on each JWC
Group Stockholder (other than AT&T) as if such JWC Group Stockholder (other than
AT&T) personally had taken such action, exercised such rights, power or
authority or made such decision or determination in such Stockholder's
individual capacity. Each such JWC Group Stockholder (other than AT&T) further
acknowledges that the foregoing appointment and designation shall be deemed to
be coupled with an interest and shall survive the death or incapacity of such
JWC Group Stockholder (other than AT&T). The other parties hereto are and will
be entitled to rely on any action taken or any notice given by the JWC Group
Stockholder Representative and are and will be entitled and authorized to give
notices only to the JWC Group Stockholder Representative for any notice
contemplated by this Agreement to be given to any such person. A successor to
the JWC Group Stockholder Representative may be chosen by a majority in interest
of the JWC Group Stockholders (other than AT&T), PROVIDED that notice thereof is
given by the new JWC Group Stockholder Representative to the Company.

              (b) The JWC Group Stockholder Representative shall not be
liable to the JWC Group Stockholders for the performance of any act or the
failure to act under or in connection with this Agreement so long as he acted or
failed to act in good faith in what he believed to be the scope of his authority
and for a purpose which he believed to be in the best interests of the JWC Group
Stockholders (other than AT&T). Each of the JWC Group Stockholders (other than
AT&T) will indemnify the JWC Group Stockholder Representative, from and against
any loss, liability, damage, deficiency, cost and expense (including without
limitation reasonable expenses of investigation and reasonable attorney's fees
incurred in connection with any claim, suit or proceeding brought against him)
incurred or sustained by him as a result of his individual acts or omissions in
connection with this Agreement, so long as he acted or failed to act in good
faith.

     14.2     NOTICES. All notices or other communications hereunder shall be in

     14.3     ENTIRE AGREEMENT; AMENDMENT; CONSENTS.

              (a) This Agreement constitutes the entire agreement among the
parties with respect to the subject matter hereof and supersedes all other prior
agreements and understandings, both written and oral, among the parties or any
of them with respect to the subject matter hereof, including, without
limitation, the Former Shareholders' Agreement.

              (b) No change or modification of this Agreement shall be

the Company, the Dobson Partnership, the holders of a majority of the shares of
each class of Common

<PAGE>

Stock and Preferred Stock and each of JWC and AT&T so long as they hold their
respective Relevant Percentage Interests; PROVIDED, HOWEVER, that in the event
any party hereto shall cease to own any shares of Company Stock such party
hereto shall cease to be a party to this Agreement and the rights and
obligations of such party hereunder shall terminate.

              (c) Whenever in this Agreement the consent or approval of a
Stockholder is required, except as expressly provided herein, such consent or
approval may be given or withheld in the sole and absolute discretion of each
Stockholder.

     14.4     TERM.

              (a) This Agreement shall terminate upon the earliest to occur
of any of the following events and PROVIDED that no Subordinated Put Notes are
outstanding:

                  (i)   The consent in writing of all of the parties hereto; or

                  (ii)  December 23, 2010; or

                  (iii) One Stockholder shall Beneficially Own all of the

              (b) In the event that JWC shall Beneficially Own less than 35%
of shares of Common Stock or Class E Preferred Stock received from conversion of
the original Class D Preferred Stock investment (in each case on an
"as-if-converted" basis) Beneficially Owned by JWC on the Amendment and
Restatement Date, the provisions of Section 3.1(a)(i) shall terminate. In the
event the provisions of Section 3.1(a)(i) are terminated pursuant to this
Section 14.3(b), the director designated by JWC pursuant to Section 3.1(a)(i),
shall resign (or the other directors or Stockholders shall remove such director
from the Board of Directors) and the remaining directors shall take such action
so that the number of directors constituting the entire Board of Directors is
accordingly reduced.

              (c) In the event that AT&T shall Beneficially Own less than
50% of shares of Common Stock or Class E Preferred Stock received from
conversion of the original Class D Preferred Stock investment (in each case on
an "as-if-converted" basis) Beneficially Owned by AT&T on the Amendment and

shall resign (or the other directors or Stockholders shall remove such director
from the Board of Directors) and the remaining directors shall take such action
so that the number of directors constituting the entire Board of Directors is
accordingly reduced.

<PAGE>

              Notwithstanding anything in this Agreement to the contrary,
the holder of any Subordinated Put Note shall be entitled to all of the rights
and benefits of the Cash Equity Investors hereunder and under the Certificate of
Designations for the Class D Preferred Stock and the Investment and Transaction
Agreement, as if such holder still held the shares of Class D Preferred Stock
for which such Subordinated Put Note was issued until such Subordinated Put Note
has been paid in full.

     14.5    SURVIVAL. Nothing contained in Section 14.5 shall impair any
rights or obligations of any party hereto arising prior to the time of the
termination of this Agreement, or which may arise by an event causing the
termination of this Agreement. The provisions of Article 5 shall survive any
termination of this Agreement and shall continue in full force and effect until
December 23, 2018. The provisions of Section 6.3 and Section 14 shall survive
the termination of this Agreement.

     14.6     WAIVER. No failure or delay on the part of any Stockholder in
exercising any right, power or privilege hereunder, nor any course of dealing
between the Company and any Stockholder shall operate as a waiver thereof nor
shall any single or partial exercise of any right, power or privilege hereunder
preclude the simultaneous or later exercise of any other right, power or
privilege. The rights and remedies herein expressly provided are cumulative and
not exclusive of any rights and remedies which any Stockholder would otherwise
have. No notice to or demand on the Company in any case shall entitle the
Company to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Stockholders or any of
them to take any other or further action in any circumstances without notice or
demand.

     14.7     OBLIGATIONS SEVERAL. The obligations of each Stockholder under
this Agreement shall be several with respect to each such Stockholder.

     14.8     GOVERNING LAW. This Agreement shall be governed and construed in
accordance with the law of the State of New York without reference to the
conflicts of law principles thereof.

     14.9     DISPUTE RESOLUTION; WAIVER OF JURY TRIAL.

              (a) The parties shall use and strictly adhere to the following
dispute resolution processes, except as otherwise expressly provided in this
Section 14.9, to resolve any and all disputes, controversies or claims, whether
based on contract, tort, statute, fraud, misrepresentation or any other legal or
equitable theory (hereinafter, "Dispute(s)"), arising out of or relating to this
Agreement (and any prior agreement this Agreement supersedes), including without
limitation, its making, termination, non-renewal, its alleged breach and the
subject matter of this Agreement (E.G., products or services furnished hereunder
or those related to those furnished):

<PAGE>

              (b) The parties shall first attempt to settle each Dispute
through good faith negotiations. The aggrieved party shall initiate such
negotiations by giving the other party(ies) written notice of the existence and
nature of the Dispute. The other party(ies) shall in a writing to the aggrieved
party acknowledge such notice of Dispute within ten (10) business days. Such
acknowledgment may also set forth any Dispute that the acknowledging party
desires to have resolved in accordance with this Section.

              (c) Thereafter, if any Dispute is not resolved by the parties
through negotiation within thirty (30) calendar days of the date of the notice
of acknowledgment, either party may terminate informal negotiations with respect
to that Dispute and have the right, by delivery of written notice thereof (the
"Arbitration Notice") to the other party, to submit the matter to be finally
settled by arbitration in accordance with the Commercial Arbitration Rules then
in effect of the American Arbitration Association, as modified herein (the "AAA
Rules"). The place of arbitration shall be Oklahoma City, Oklahoma. All matters
so submitted to arbitration shall be settled by three arbitrators. The disputing
party and the Company shall each designate one arbitrator within 20 days of the
delivery of the Arbitration Notice. If either the disputing party or the Company
fails so to timely designate an arbitrator, the matter shall be resolved by the
one arbitrator timely designated. The disputing party and the Company shall
cause the designated arbitrators to mutually agree upon and to designate a third
arbitrator, PROVIDED, HOWEVER, that failing such agreement within 45 days of
delivery of the Arbitration Notice, the third arbitrator shall be appointed in
accordance with the AAA Rules. The disputing party and the Company, shall be
responsible for the payment of the fees and expenses of their respectively
designated arbitrators and shall bear equally the fees and expenses of the third
arbitrator. The disputing party and the Company, shall cause the arbitrators to
decide the matter to be arbitrated pursuant hereto within 60 days after the
appointment of the last arbitrator. The arbitral tribunal is not empowered to
award damages in excess of compensatory damages and each party hereby
irrevocably waives any right to recover punitive, exemplary or similar damages
with respect to any Dispute. The final decision of the majority of the
arbitrators shall be furnished to the disputing party and the Company and each
of the Stockholders in writing and shall constitute a conclusive determination
of the matter in question, binding upon JWC, the Company and the Stockholders
and shall not be contested by any of them. Such decision may be used in a
court of law only for the purpose of seeking enforcement of the arbitrators'
award. Any arbitration proceeding, decision or award rendered hereunder and the
validity, effect and interpretation of this arbitration agreement shall be
governed by the Federal Arbitration Act, 9 U.S.C. Sections 1-16, and judgment
upon any award may be entered in any court of competent jurisdiction.

              (d) The Company and each of the Stockholders hereby
irrevocably consents to the exclusive jurisdiction of the state or federal
courts in the State of New York, and all state or federal courts competent to
hear appeals therefrom, over any

<PAGE>

actions which may be commenced against any of them under or in connection with
this Agreement. The Company and each Stockholder hereby irrevocably waive, to
the fullest extent permitted by applicable law, any objection which any of them
may now or hereafter have to the laying of venue of any such dispute brought in
such court or any defense of inconvenient forum for the maintenance of such
dispute in the Southern District of New York and New York County. The Company
and each Stockholder hereby agree that a judgment in any such dispute may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. The Company and each Stockholder hereby consent to process
being served by any party to this Agreement in any actions by the transmittal of
a copy thereof in accordance with the provisions of Section 14.2.

              (e)EACH OF THE PARTIES HERETO, AFTER CONSULTING WITH COUNSEL
WAIVE THEIR RIGHTS, IF ANY, TO JURY TRIAL IN RESPECT TO ANY DISPUTE OR CLAIMS
BETWEEN OR AMONG THE PARTIES TO THIS AGREEMENT RELATING TO OR IN RESPECT OF THIS
AGREEMENT, ITS NEGOTIATION, EXECUTION, PERFORMANCE, SUBJECT MATTER, OR ANY
COURSE OF CONDUCT OR DEALING OR ACTIONS UNDER OR IN RESPECT OF THIS AGREEMENT,
INCLUDING, WITHOUT LIMITATION ANY CLAIM UNDER THE SECURITIES ACT, THE SECURITIES
EXCHANGE ACT OF 1934, AS AMENDED, ANY OTHER STATE OR FEDERAL LAW RELATING TO
SECURITIES OR FRAUD OR BOTH, THE RACKETEER INFLUENCED AND CORRUPT ORGANIZATIONS
ACT, AS AMENDED, OR FEDERAL OR STATE COMMON LAW.

     14.10    BENEFIT AND BINDING EFFECT; SEVERABILITY.  This Agreement shall 
be binding upon and shall inure to the benefit of the Company, its successors 
and assigns, and each of the Stockholders and their respective executors, 
administrators and personal representatives and heirs and permitted assigns.  
If any term or other provision of this Agreement is invalid, illegal or 
incapable of being enforced by any law or public policy or any listing 
requirement applicable to the Common Stock, all other terms and provisions of 
this Agreement shall nevertheless remain in full force and effect. Upon such 
determination that any term or other provision is invalid, illegal or 
incapable of being enforced, the parties hereto affected by such 
determination in any material respect shall negotiate in good faith to modify 
this Agreement so as to effect the original intent of the parties as closely 
as possible in an acceptable manner in order that the provisions hereof are 
given effect as originally contemplated to the greatest extent possible.

     14.11    AMENDMENT OF BY-LAWS. The Stockholders agree that the terms of
this Agreement shall supersede any inconsistent provision that is contained in
the Restated By-Laws and, to the extent required by Oklahoma law or the Restated
By-Laws, this Agreement shall be deemed to constitute a written action taken by
the Stockholders of the Company and shall be deemed an amendment of the Restated
By-Laws.

<PAGE>

     14.12    FCC AND REGULATORY APPROVALS. Notwithstanding anything contained
in this Agreement to the contrary, no transaction or action contemplated herein
shall be consummated and no interests or rights transferred, converted or
exchanged prior to receiving FCC approvals with respect thereto to the extent
such FCC approvals are necessary.

     14.13    EXPENSES. All attorneys' fees incurred by the Stockholders in
connection with this Agreement (including, without limitation, in the
preparation of notices (and responses thereto) and consents) shall be borne by
the Stockholder(s) incurring such fees.

     14.14    ATTORNEYS' FEES. In any action or proceeding brought to enforce
any provision of this Agreement, or where any provision hereof is validly
asserted as a defense, the successful party shall be entitled to recover
reasonable attorneys' fees in addition to any other available remedy.

     14.15    HEADINGS. The captions in this Agreement are for convenience only
and shall not be considered a part of or affect the construction or
interpretation of any provision of this Agreement.

     14.16    COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument.

<PAGE>

     IN WITNESS WHEREOF, each of the parties has executed or consent this
Agreement to be executed by its duly authorized officers as of the date first
written above.
