                               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.
 
                                  THE COMPANY
 
   
    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
September 30, 1998, our cellular systems covered a population of 2.8 million in
Arizona, California, Kansas, Maryland, Missouri, Oklahoma, Pennsylvania and
Texas. On December 23, 1998, we acquired Sygnet for $337.5 million in cash.
Sygnet and its subsidiary own and operate cellular telephone systems covering a
population of 2.4 million in northeastern Ohio, western Pennsylvania and western
New York. For the nine months ended September 30, 1998, after giving pro forma
effect to our April 1, 1998 acquisition of California 4 RSA and to the Sygnet
acquisition as if each acquisition had occurred on January 1, 1997, we would
have had revenue of $176.5 million, an operating loss of $13.7 million and
Adjusted EBITDA of $75.9 million.
    
 
    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
 
                                       1
<PAGE>
systems in neighboring MSAs and other MSAs that allow customers to roam at
competitive prices that, in certain instances, are comparable to our home area
rates.
 
    We are organized to establish and maintain a strong and visible local
presence while achieving economies of scale and synergies through regional and
centralized functions. 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. In addition to our acquisition of Sygnet, 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. Recently, we 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.
 
    The following table sets forth certain data with respect to our existing
cellular systems and the systems which have been or will be acquired in our
acquisitions of Sygnet, Texas 10 RSA, Ohio 2 RSA and Maryland 1 RSA
(collectively, the "Recent and Pending Acquisitions"):

(1) As of September 30, 1998.
 
(2) Determined by dividing total subscribers by the total Pops covered by the
    applicable FCC cellular license or authorizations held by us or our
    subsidiaries.
 
(3) The Central Region consists of Oklahoma 5 RSA and Oklahoma 7 RSA, Texas 2
    RSA, Enid, Oklahoma MSA, Oklahoma 2 RSA, Texas 16 RSA, Kansas 5 RSA,
    Missouri 1 RSA, Missouri 4 RSA and Missouri 5 RSA. Our FCC licenses for
    Oklahoma 5 RSA and Oklahoma 7 RSA do not include Kingfisher and Blaine
    Counties, approximately one-half of Dewey County (total Pops
 
                                       2

    estimated by us to be 3,000 for the area in Dewey County not covered by our
    FCC license), Harmon and Greer Counties. We also own a 5% interest in a
    partnership which owns the cellular system in Oklahoma 3 RSA which has total
    Pops of 205,600. Information regarding Oklahoma 3 RSA is excluded because we
    do not manage the system. Our license for Missouri 5 RSA covers only the
    Linn County portion of the RSA.
 
(4) East Maryland consists of Maryland 2 RSA. West Maryland includes Cumberland,
    Maryland MSA, Hagerstown, Maryland MSA, Maryland 3 RSA and Pennsylvania 10
    West RSA. The FCC license for the Pennsylvania 10 West RSA covers only
    Bedford County. Information for this RSA relates only to the area covered by
    our FCC licenses. Upon the closing of the Maryland 1 Acquisition, Maryland 1
    will become part of our West Maryland market area.
 
(5) We completed the acquisitions of the FCC licenses for Ohio 2 RSA on
    September 2, 1998 and Texas 10 RSA on December 2, 1998. We are negotiating
    with AirTouch in Ohio 2 RSA and with AT&T Wireless in Texas 10 RSA for the
    purchase of subscribers and the lease of certain equipment necessary to
    operate systems in each area. The purchase price for each of Ohio 2 RSA and
    Texas 10 RSA is being held in escrow pending resolution of claims made
    against the titles to the FCC licenses of our respective sellers. See "Risk
    Factors--Recent Acquisitions."

    Erie, Pennsylvania MSA, New York 3 RSA, Pennsylvania 1 RSA, Pennsylvania 2
    RSA, Pennsylvania 6 RSA and Pennsylvania 7 RSA. Sygnet had previously
    operated Pennsylvania 2 RSA under an interim operating authority which was
    terminated on June 3, 1997 when the FCC awarded a permanent license to
    Pinellas Communications. On June 8, 1998, Sygnet entered into an agreement
    to purchase Pennsylvania 2 RSA for $6.0 million in cash (the "Pennsylvania 2
    Acquisition"). Since then, Sygnet has been operating Pennsylvania 2 RSA
    under a management and lease agreement with the present owner of
    Pennsylvania 2, which will continue in effect until the FCC's grant of the
    license to the present owner is no longer subject to reconsideration or
    judicial review.
 
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 MSA at favorable rates.
 
    - to distinguish ourself as the local market's leading cellular services
      provider, stressing our service quality, local sales offices and
      commitment to the community.
 
    - 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 its 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
 
    Our wholly owned subsidiary, Logix Communications Enterprises, Inc.
("Logix,"), provides 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 and incumbent local exchange services
in Oklahoma. Logix recently began offering switch-based integrated carrier
provider services in Oklahoma City, Tulsa and Amarillo. In
 
                                       3
<PAGE>
addition, since our acquisition of American Telco, Inc. and its affiliate,
American Telco Network Services, Inc. on June 15, 1998, Logix has offered these
services in Houston, Austin, Dallas, Fort Worth and San Antonio.
 
    We have designated Logix an unrestricted subsidiary with respect to the
12 1/4% Senior Exchangeable Preferred Stock. As an unrestricted subsidiary,
Logix is not subject to certain covenant 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. Holders of our 12 1/4% Senior Exchangeable Preferred Stock will
not participate in our distribution of Logix stock. Logix is accounted for as a
discontinued operation in our consolidated financial statements.

    - Sygnet repurchased (the "Sygnet Note Repurchase") all of its outstanding
      11 1/2% Senior Notes due 2006 (the "Sygnet Notes") pursuant to Sygnet's
      offer to purchase the Sygnet Notes;
 
    - we repurchased certain shares of our outstanding common and preferred
      stock with a portion of the net proceeds of the Equity Investments and
      borrowings under one of our existing bank facilities; and

      cellular towers owned by Sygnet for $25.0 million in cash using funds

                   SUMMARY OF THE TERMS OF THE EXCHANGE OFFER
 
   
    The Exchange Offer relates to the exchange of up to 67,148 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 of
our 12 1/4% Senior Exchangeable Preferred Stock 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, as amended (the "Securities Act") 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, dated
December 23, 1998 between the Company and NationsBanc Montgomery Securities LLC,
the Initial Purchaser in the private offering.
    
 
   
<TABLE>
<S>                                 <C>
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 Shares.
The Exchange Offer................  We are offering to exchange one New Share for each Old
                                    Share. All outstanding Old Shares that are validly
                                    tendered and not validly withdrawn will be exchanged. 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.
Resale of New Shares..............  Based on interpretations by the staff of the 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 prospectus delivery provisions
                                    of the Securities Act, 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 Shares directly from us for resale
                                          pursuant to Rule 144A or any other available
                                          exemption under the Securities Act of 1933; and
                                        - you are not an "affiliate".
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
                                    (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 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 notes will have certain rights against
                                    our Company under the registration rights agreement
                                    executed as part of the offering of the outstanding
                                    notes should we fail to consummate the Exchange Offer.
Conditions to the Exchange
  Offer...........................  The Exchange Offer is subject to certain conditions,
                                    which may be waived by the Company. See "The Exchange

                                    of Transmittal as though you had executed our Letter of
                                    Transmittal.
Special Procedures for Beneficial

                                    name does not appear on a security position listing of
                                    the Depository Trust Company as the holder of such Old
                                    Shares or if you are a beneficial owner of Old Shares
                                    that are registered in the name of a broker, dealer,
                                    commercial bank, trust company or other nominee and you
                                    wish to tender such Old Shares or registered Old Shares

                                    such beneficial holder must, prior to completing and

Acceptance of Outstanding Old
  Shares and Delivery of New
  Shares..........................  Subject to certain conditions (as summarized above in
                                    "Termination of the Exchange Offer" and described more
                                    fully under "The Exchange Offer--Conditions of the
                                    Exchange Offer"), we will accept for exchange any and
                                    all outstanding Old Shares notes which are properly
                                    tendered in the Exchange Offer prior to 5:00 p.m., New
                                    York City time, on the Expiration Date. The New Shares

Certain U.S. Federal Income Tax
  Consequences....................  The exchange of the Old Shares will generally not be a
                                    taxable exchange for United States federal income tax
                                    purposes. We believe you will not recognize any taxable
                                    gain or loss or any income as a result of such exchange.
Use of Proceeds...................  We will not receive any proceeds from the issuance of
                                    New Shares pursuant to the Exchange Offer. We will pay
                                    all expenses incident to the Exchange Offer.

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 January
                                    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 (the
                                    "Certificate of Designation"). 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.

                                    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.

                                          senior to the Preferred Stock. As of the date of
                                          this Prospectus, all outstanding of our capital
                                          stock, other than outstanding Senior Preferred
                                          Stock, would rank junior to the Preferred Stock.
                                          At September 30, 1998, the Company had $185.5
                                          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 are
                                    satisfied.
 
Certain Covenants.................  The Certificate of Designation 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

                                    We have designated our subsidiaries, Logix,
                                    Dobson/Sygnet Communications Company and Sygnet as
                                    unrestricted subsidiaries. As a result, Logix,
                                    Dobson/Sygnet Communications Company and Sygnet are not
                                    subject to the covenants contained in the Certificate of
                                    Designation.
 
Change of Control.................  Upon certain 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."

                                    Stock outstanding on the Exchange Date (as defined 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 a principal amount of up to 35% of the
                                    principal amount of the Exchange Debentures, at a
                                    redemption price equal to 112.250% of the principal
                                    amount of the Exchange Debentures, plus accrued
                                    interest, with the proceeds of one or more sales of its
                                    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 the Senior
                                    Exchange Debentures that may be issued with respect to
                                    the Senior Preferred Stock.
 
Ranking...........................  The Exchange Debentures will be senior subordinated
                                    indebtedness, ranking junior to all of our existing and
                                    future Senior Indebtedness (as defined under
                                    "Description of the Exchange Debentures") and senior to
                                    all of our subordinated indebtedness. The Exchange
                                    Debentures will rank equally with any Senior Exchange
                                    Debentures that may be issued. At September 30, 1998,
                                    assuming the Sygnet acquisition and its related
                                    financing had been completed at that time, we would have
                                    had $1,054.9 million of consolidated indebtedness
                                    outstanding, and our subsidiaries would have had $894.9
                                    million of indebtedness outstanding, all of which would
                                    have been effectively senior to the Exchange Debentures.
 
Certain Covenants.................  The indenture under which the Exchange Debentures would
                                    be issued will contain certain covenants that restrict
                                    our ability and the ability of certain of our
                                    subsidiaries to:
 
                                        - incur additional indebtedness,
 
                                        - 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,

                                    unrestricted subsidiaries. As a result, Logix,
                                    Dobson/Sygnet Communications Company and Sygnet are not
                                    subject to the covenants contained in the Exchange
                                    Debenture indenture.
 
Registration Requirements.........  The Exchange Debentures may not be issued unless such
                                    issuance is registered under the Securities Act or is
                                    exempt from registration.
 
Change of Control.................  Upon certain change of control events, we must make an

                 SUMMARY PRO FORMA CONSOLIDATED FINANCIAL DATA
 
    The following summary unaudited pro forma consolidated financial data were
derived from the pro forma condensed consolidated financial statements included
elsewhere in this Prospectus. The pro forma statement of operations data for the
year ended December 31, 1997 give effect to the consummation of the West
Maryland Acquisition and the Arizona 5 Acquisition and related financing and the
1998 Transactions (as such terms are defined under "Certain Terms"), including
the Sygnet acquisition and its related financing, as if they occurred on January
1, 1997. The pro forma statement of operations data for the nine months ended
September 30, 1998 give effect to the 1998 Transactions, including the Sygnet
acquisition and its related financing, as if they occurred on January 1, 1997.
The pro forma balance sheet data give effect to the Sygnet acquisition and its
related financing as if they occurred on September 30, 1998. The summary
unaudited pro forma consolidated financial data are based on currently available
information and certain assumptions that management believes are reasonable. The
pro forma financial information does not purport to represent what our results
of operations would have been if the Sygnet acquisition, the Sygnet Financing
and the other Transactions had been completed on the dates indicated, nor does
it purport to indicate the future financial position or results of our future
operations. The pro forma consolidated financial data should be read in
conjunction with "Use of Proceeds," "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 thereto included elsewhere in this

- ------------------------------
 (1) Reflects minority interests in partnerships in which we own the majority
    interests.
 
 (2) Extraordinary items reflect gain or (loss) related to early extinguishment
    of debt.
 
   
 (3) Adjusted EBITDA represents earnings before interest expense, income taxes,
    depreciation, amortization, extraordinary items and changes in accounting
    principles. Adjusted EBITDA is provided because it is a measure commonly
    used in the telecommunications industry to determine a company's ability to
    incur or service debt. Adjusted EBITDA is not derived pursuant to generally
    accepted accounting principles and should not be construed as an alternative
    to net income, as a measure of performance, or to cash flows, as a measure
    of liquidity. The calculation of Adjusted EBITDA does not include our
    commitments for capital expenditures or payments of debts and should not be
    deemed to represent funds available to us.
    
 
   
 (4) Includes Adjusted EBITDA attributable to minority interests in subsidiaries
    in which we own a majority interest. The portion of Adjusted EBITDA
    attributable to minority interests was $2.9 million for the year ended
    December 31, 1997 and $3.7 million for the nine months ended September 30,
    1998.
    
 
   
 (5) On a pro forma basis, our earnings would have been insufficient to cover
    combined fixed charges and preferred stock dividends by $172.0 million for
    the year ended December 31, 1997 and by $129.3 million for the nine months
    ended September 30, 1998. "Earnings" is defined as earnings before
    extraordinary items and accounting changes, interest expense, amortization
    of deferred financing costs, taxes and the portion of rent expense under
    operating leases representative of interest. Fixed charges consist of
    interest expense, amortization of deferred financing costs and a portion of
    rent expense under operating leases representative of interest.
    
 
 (6) Determined by dividing our total ending cellular subscribers for the period
    by the estimated total Pops covered by applicable FCC cellular licenses or
    authorizations held by us.
 
 (7) Churn means the number of cellular subscriber cancellations per period as a
    percentage of the weighted average total cellular subscribers during such
    period. Churn is stated as the average monthly churn rate for the period.
 
 (8) Excludes roaming revenue and equipment revenue.
 
 (9) Determined by dividing cellular marketing and selling costs by the gross
    cellular subscribers added during each period. Cellular marketing and
    selling costs represent selling expenses and losses incurred on equipment
    sales.

 (1) Includes the operations of our Kansas/Missouri properties from March 19,
     1996, the date we acquired them.
 
 (2) Includes the operations of West Maryland, East Maryland and Arizona 5 from
     the dates they were acquired by the Company. West Maryland was acquired on
     February 28, 1997, East Maryland on March 3, 1997 and Arizona 5 on October
     1, 1997.
 
 (3) Includes the operations of West Maryland and East Maryland from the dates
     we acquired them.
 
 (4) Includes the operations of Texas 16, California 4, Santa Cruz and
     California 7 from the dates we acquired them. Texas 16 was acquired on
     January 26, 1998; California 4 on April 1, 1998, Santa Cruz on June 16,
     1998; and California 7 on July 29, 1998.
 
 (5) Reflects minority interests in partnerships in which we own the majority
     interests.
 
 (6) Extraordinary items reflect gain or (loss) related to early extinguishment
     of debt.
 
 (7) Adjusted EBITDA represents earnings before interest expense, income taxes,
     depreciation, amortization, extraordinary items and changes in accounting
     principles. Adjusted EBITDA is provided because it is a measure commonly
     used in the telecommunications industry to determine a company's ability to
     incur or service debt. Adjusted EBITDA is not derived pursuant to generally
     accepted accounting principles and should not be construed as an
     alternative to net income, as a measure of performance, or to cash flows,
     as a measure of liquidity. The calculation of Adjusted EBITDA does not
     include our commitments for capital expenditures or payments of debts and
     should not be deemed to represent funds available to us.
 
 (8) Includes Adjusted EBITDA attributable to minority interests in subsidiaries
     in which we own a majority interest. The portion of Adjusted EBITDA
     attributable to minority interests was $2.0 million, $2.3 million, $2.9
     million, $2.0 million and $3.7 million for the years ended December 31,
     1995, 1996 and 1997 and for the nine months ended September 30, 1997 and
     1998, respectively.
 
   
 (9) 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, by $11.2
     million for the nine months ended September 30, 1997 and by $49.8 million
     for the nine months ended September 30, 1998. "Earnings" is defined as
     earnings before extraordinary items and accounting changes, interest
     expense, amortization of deferred financing costs, taxes and the portion of
     rent expense under operating leases representative of interest. Fixed
     charges consist of interest expense, amortization of deferred financing
     costs and a portion of rent expense under operating leases representative
     of interest.
    
 
 (10) Determined by dividing our total ending cellular subscribers for the
      period by the estimated total Pops covered by applicable FCC cellular
      licenses.
 
 (11) Churn means the number of cellular subscriber cancellations per period as
      a percentage of the weighted average total cellular subscribers during
      such period. Churn is stated as the average monthly churn rate for the
      period.
 
 (12) Excludes roaming and equipment revenue.
 
 (13) Determined by dividing cellular marketing and selling costs by the gross
      cellular subscribers added during each period. Cellular marketing and
      selling costs represent selling expenses and losses incurred on equipment
      sales.

    accounting principles. Adjusted EBITDA is provided because it is a measure
    commonly used in the telecommunications industry to determine a company's
    ability to incur or service debt. Adjusted EBITDA is not derived according
    to generally accepted accounting principles and should not be considered as
    an alternative to net income, as a measure of performance, or to cash flows,
    as a measure of liquidity. The calculation of Adjusted EBITDA does not
    include Sygnet's commitments for capital expenditures or payments of debts
    and should not be deemed to represent funds available to Sygnet.
    
 
   
(4) Sygnet's earnings were insufficient to cover combined fixed charges and
    preferred stock dividends by $4.6 million for the year ended December 31,
    1996, by $22.7 million for the year ended December 31, 1997, by $16.2
    million for the nine months ended September 30, 1997 and by $6.6 million for
    the nine months ended September 30, 1998. "Earnings" is defined as earnings
    before extraordinary items and accounting changes, interest expense,
    amortization of deferred financing costs, taxes and the portion of rent
    expense under operating leases representative of interest. Fixed charges
    consist of interest expense, amortization of deferred financing costs and a
    portion of rent expense under operating leases representative of interest.
    
 
(5) Determined by dividing Sygnet's total ending cellular subscribers for the

                                  RISK FACTORS
 
    YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING FACTORS, AS WELL AS THE OTHER
INFORMATION CONTAINED IN THIS PROSPECTUS, IN EVALUATING US AND OUR BUSINESS.
 
   
WE HAVE A SIGNIFICANT AMOUNT OF INDEBTEDNESS
    
 
   
    At September 30, 1998, assuming that our acquisition of Sygnet and the
related financing were completed at that time, we would have had approximately
$1,054.9 million of consolidated indebtedness, all of which would rank senior to
the Preferred Stock, $375.5 million aggregate liquidation preference of
mandatorily redeemable preferred stock, a deficit in consolidated stockholders'
equity of $128.2 million and $206.6 million of availability (subsequent to which
$55.0 million was borrowed to fund our acquisition of Texas 10 RSA on December
2, 1998) under the New Credit Facilities and the Existing Credit Facilities. The
terms of the Preferred Stock also allow us to incur additional indebtedness in
the future. At December 31, 1997, assuming that the West Maryland Acquisition,
the Arizona 5 Acquisition and its related financing, and the 1998 Transactions,
including our acquisition of Sygnet and the related financing were completed at
that time, our Adjusted EBITDA minus interest expense, preferred stock dividends
and capital expenditures (excluding acquisition costs) would have been $(116.9)
million, and our earnings would have been insufficient to cover our fixed
charges and preferred stock dividends by $172.0 million. For the nine months
ended September 30, 1998, under the same assumptions, our Adjusted EBITDA minus
interest expense, preferred stock dividends and capital expenditures (excluding
acquisition costs) would have been $(76.2) million, and our earnings would have
been insufficient to cover our fixed charges and preferred stock dividends by
$129.3 million. See "Description of the Preferred Stock," "Description of the
Exchange Debentures," "Description of Certain Indebtedness" and "Description of
Capital Stock."
    
 
    In addition, we have designated our subsidiaries, Logix, Dobson/Sygnet
Communications Company ("Dobson/Sygnet") and Sygnet as unrestricted subsidiaries
and they will not be subject to the covenants contained in the Certificate of
Designation. There will be no limit under the Certificate of Designation on the
amount of debt that Logix, Dobson/Sygnet and Sygnet 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 make
      cash dividend payments on the Preferred Stock or cash interest payments 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 will be limited;
 
    - a substantial portion of our future cash flow from operations, if any,
      will be required to pay principal and interest payments on its
      indebtedness and will not be available for our business;
 
    - our flexibility in planning for, or reacting to changes in, our business
      and our ability to take advantage of future business opportunities may be
      restricted;
 
    - we may be more highly leveraged than certain of our competitors, which may
      place us at a competitive disadvantage; and
 
    - our high degree of leverage could make us more vulnerable in the event of
      a downturn in our business.
 
   
WE EXPECT TO REQUIRE SUBSTANTIAL AMOUNTS OF CAPITAL
    
 
    We have required, and will likely continue to require, substantial capital
to further develop and expand our cellular systems. We have budgeted $30.2
million for capital expenditures in 1998, of which we have expended $23.7
million as of September 30, 1998. We have budgeted $50.2 million for capital
 
                                       22
<PAGE>
   
expenditures in 1999, approximately $40.0 million of which is for the purchase
of cell site and switching equipment. These amounts include expenditures related
to the systems that we will acquire in the Recent and Pending Acquisitions other
than acquisition costs. 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 and
within the limitations contained in the Certificate of Designation, the
certificate of designation for the Senior Preferred Stock, the indenture
relating to our 11 3/4% Senior Notes due 2007 (the "Senior Notes Indenture"),
the certificates of designation for each of our other series of preferred stock,
the terms of the Existing Credit Facilities and New 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 as a result of the
Transactions, and we and our subsidiaries are, and will continue to be, subject
to significant financial restrictions and limitations. In order for us to be
able to meet debt service and dividend requirements, including obligations under
the Senior Notes, the Senior Preferred Stock, the Preferred Stock, the
Dobson/Sygnet Notes and the Credit Facilities, we must successfully implement
our strategy. Our business strategy is to focus on 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.
 
   
    Furthermore, if we are unable to satisfy any of the covenants under the
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 the
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, including the Logix Notes. See "--Restrictions Imposed in
our Governing Instruments May Adversely Affect our Operations." Our ability to
borrow under the Credit Facilities will be limited by the requirement that, on a
quarterly basis beginning June 30, 2000, the amount available under the Existing
Credit Facilities will reduce until the facilities terminate in June 2006, and
beginning December 2000, the amount available under the New Credit Facilities
will reduce until the facility terminates in December 2007. The reduction in
availability may require that we make significant principal payments thereunder.
See "Description of the Preferred Stock," "Description of the Exchange
Debentures" and "Description of Certain Indebtedness."
    
 
   
WE MAY BE UNABLE TO REFINANCE OUR INDEBTEDNESS
    
 
   
    We will need to refinance our indebtedness under the Credit Facilities, the
Senior Notes and the Dobson/Sygnet Notes at their respective maturities. We will
also need to refinance our mandatory redemption obligations under our preferred
stock. 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 the indebtedness and other factors, including market
conditions, beyond our control. The Existing Credit Facilities mature in 2006
and the New Credit Facilities mature in 2007. The Credit Facilities
    
 
                                       23
<PAGE>
   
require substantial mandatory prepayments prior to such dates. Our outstanding
Senior Notes ($160.0 million principal amount) mature April 15, 2007; and the
Dobson/Sygnet Notes ($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." We must redeem outstanding 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. See "Description of the Preferred Stock,"
"Description of the Exchange Debentures," "Description of Certain Indebtedness"
and "Description of Capital Stock."
    
 
   
    If any of this indebtedness or preferred stock cannot be refinanced, it may
cause a default thereunder and under other of our obligations and those of our
subsidiaries. In addition, in the event the 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. We cannot assure you
that we could obtain any such financing or refinancing on terms that are
acceptable to us, if at all. 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 September 30, 1998, approximately 69.3% of our total assets consisted of
intangible assets, principally licenses granted by the FCC (80.3% on a pro forma
basis, after giving effect to the Sygnet Acquisition and the related financing).
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 ARE JUNIOR SECURITIES
    
 
   
    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 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 on the Senior
Preferred Stock and the Preferred Stock. The Preferred Stock also effectively
ranks junior to all liabilities, including indebtedness, of our subsidiaries. At
September 30, 1998, assuming that the Sygnet acquisition and the related
financing were completed at that time, we would have had approximately $1,151.7
million of consolidated indebtedness and other liabilities, excluding deferred
credits for income taxes, outstanding ranking senior to the Preferred Stock and
our subsidiaries would have had $976.7 million of liabilities, excluding
deferred credits for income taxes. See "--We Have a Significant Amount of
Indebtedness," "--We May Be Unable to Meet Our Debt Service Requirements and
Dividend Obligations" and "Description of the Preferred Stock--Ranking."
    
 
    If the Preferred Stock is exchanged for Exchange Debentures, 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 the Senior Notes and the Existing Credit Facilities. The Exchange
Debentures will also rank effectively junior to all liablities, including
indebtedness, of our
 
                                       24
<PAGE>
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 preferred
stock which ranks 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 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 the 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.
 
   
WE ARE DEPENDENT ON CASH FLOWS FROM 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 the Senior Notes, 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 the 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 Notes and the Credit Facilities). We
will not be subordinated to such creditors if we are a creditor of such
subsidiary, in which case our claims would still be effectively subordinated to
any security interest in the assets of such subsidiary senior to that held by
us.
 
   
WE MAY BE UNABLE TO PAY CASH DIVIDENDS ON THE PREFERRED STOCK
    
 
   
    Dividends on the Preferred Stock must be paid in cash commencing January 15,
2003. Under the Senior Note Indenture, we may pay cash dividends and make other
distributions on or in respect of our capital stock, including the Senior
Preferred Stock and Preferred Stock, only if certain financial tests are met. In
addition, the 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 Senior Note Indenture and the 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. 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").
    
 
                                       25
<PAGE>
   
RESTRICTIONS IMPOSED IN OUR GOVERNING INSTRUMENTS MAY ADVERSELY AFFECT OUR
  OPERATIONS
    
 
   
    The instruments governing our indebtedness and that of our subsidiaries, the
Certificate of Designation and the certificates of designation with respect to
the Senior Preferred Stock and the Other Preferred Stock impose significant
operating and financial restrictions on us and 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 Existing 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."
    
 
POSSIBLE INABILITY TO REPURCHASE OF 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 dividends or principal amount plus accrued
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 Credit Facilities, the Senior Note indenture and the certificate of
designation for the Senior Preferred Stock will prohibit us from prepaying 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 and purchase all of our 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, including
      indebtedness under the Credit Facilities, the Senior Note Indenture and
      the certificate of designation for the Senior Preferred Stock, or
    
 
    - 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 our
Senior Note Indenture. We cannot assure you that we will have enough funds
available at the time of any Change of Control offer to make any debt payment
(including repurchases of Preferred Stock or the Exchange Debentures) as
described above.
    
 
   
    The events that constitute a Change of Control under the Certificate of
Designation or our Senior Note Indenture, as the case may be, may also be events
of default under the Credit Facilities, the Senior Note Indenture and the
certificate of designation for the Senior Preferred Stock 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
    
 
                                       26
<PAGE>
debt in order to repay the lenders. Similarly, a default under the Senior
Preferred Stock could entitle the holders thereof to obtain representation on
our board of directors. 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."
 
   
WE NEED TO INTEGRATE OUR ACQUISITIONS AND MANAGE OUR GROWTH
    
 
   
    We are subject to risks that acquired systems (including those acquired in
the Sygnet acquisition) will not perform as expected and that the returns from
such systems will not support the indebtedness incurred or equity issued 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 our acquisition of the FCC license for each of 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 the seller's title to the
FCC licenses. 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 such properties
and the future cash flows therefrom. Depending upon how much we had invested in
the affected RSA, how much of that investment could be sold or salvaged 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.
    
 
   
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 Pops 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 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
its PCS system. We cannot assure you that we will be able to obtain such
financing or, if such financing is available, that it can be obtained on terms
acceptable to us and within the limitations contained in the Senior Note
Indenture, the Credit Facilities, the Certificate of Designation and the
certificates of designation for the Senior Preferred Stock and the Other
Preferred Stock. If our subsidiary which holds the PCS licenses fails to satisfy
its installment financing obligations to the FCC, the
 
                                       27
<PAGE>
PCS licenses may be canceled, 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 September 30, 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 which 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.
 
   
OUR BUSINESS IS SUBJECT TO INTENSE COMPETITION
    
 
    The telecommunications industry is highly competitive. Many of our existing
and potential competitors have substantially greater financial, personnel,
technical, marketing and other resources than do we as well as other competitive
advantages. Currently the FCC authorizes only two cellular licensees to operate
in each license area and we compete in each of our markets with one other
cellular licensee. Competition for subscribers between cellular licensees in a
given license area is based principally upon price, the services and
enhancements offered, the technical quality of the cellular system, customer
service, system coverage and capacity. We also compete, although to a lesser
extent, with resellers, paging companies and landline telephone service
providers.
 
    As a result of recent regulatory and legislative initiatives, our cellular
operations may face increased competition from entities which use other
communications technologies or other radio frequency spectrum such as broadband
PCS licensees and enhanced specialized mobile radio licensees. The FCC has
authorized as many as six broadband PCS licensees to provide services in each of
our markets, although not all of these licensees have begun servicing those
markets. Our operations may also face competition from other technologies
developed in the future including, but not limited to, satellite systems and
services provided over spectrum allocated to the Wireless Communications
Services and General Wireless Communications Services. While mobile services are
not currently feasible on Wireless Communications Services spectrum, and General
Wireless Communications Services spectrum has not been licensed, mobile
operations are not prohibited on such spectrum and may emerge at a future date.
We believe the likelihood of near-term competition from such services is reduced
because the areas in which we operate are less densely populated. We cannot
assure you, however, that one or more of the technologies currently used by us
in our business will not become inferior or obsolete at some time in the future.
See "Business-- Competition."
 
    We may not be able to continue to compete successfully and new technologies
and products that are more commercially accepted than ours may be developed.
Some competitors may market other services such as long distance services, cable
television access or landline local exchange services with their wireless
offerings. There has been a cellular industry trend of declining average revenue
per minute, as competition between service providers has led to reductions in
rates for airtime and subscriptions and other charges. We expect that this trend
will continue. See "Business--Competition" for more detailed information on our
competitive environment.
 
                                       28
<PAGE>
   
OUR BUSINESS IS AFFECTED BY FREQUENT AND SIGNIFICANT TECHNOLOGICAL CHANGES
    
 
    The telecommunications industry is subject to rapid and significant changes
in technology, including advancements protected by intellectual property laws.
Significant changes can be seen in the increasing pace of digital upgrades in
existing analog wireless systems, evolving industry standards, the availability
of new radio frequency spectrum allocations for wireless services, ongoing
improvements in the capacity and quality of digital technology, shorter
development cycles for new products and enhancements, developments in emerging
wireless transmission technologies and changes in end-user requirements and
preferences. International standards bodies and national regulators will
consider technology standards for new third-generation wireless technologies in
coming years, and we cannot assure you that its current technologies will be
compatible with such technologies. In addition, we may be required to select in
advance one technology over another. However, at the time we must make our
investment, 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.
The effect of technological changes on our business cannot be predicted, and we
cannot assure you that technological developments will not have a material
adverse effect on us.
 
   
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 "--Risks Associated with Acquisitions;
Ability to Manage Growth" and "Management."
    
 
   
WE RELY ON THE USE OF THIRD-PARTY SERVICE MARKS TO MARKET OUR PRODUCTS AND
  SERVICES
    
 
    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. Our use of the CELLULAR ONE-Registered Trademark-
service mark is governed by five-year contracts with Cellular One Group, the
owner of the service mark. These contracts begin to expire in 2001 and 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 its 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. Recently, 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 licensing, construction, operation, acquisition and sale of wireless
systems, as well as the number of cellular and other wireless licensees
permitted in each market, are regulated by the FCC. Changes in the regulation of
wireless activities and wireless carriers or the loss of any license or licensed
area could have a material adverse effect on our operations. In addition, all
cellular and PCS licenses in the United States are subject to renewal upon
expiration of their initial ten-year term. Our cellular licenses will expire at
varying dates beginning in October 2000. We believe that each of these licenses
will be renewed based upon FCC rules establishing a presumption in favor of
licensees that have complied with their regulatory
 
                                       29
<PAGE>
obligations during the initial license period. We cannot assure you, however,
that our licenses will be renewed. See "Business--Regulation."
 
   
EQUIPMENT FAILURE AND NATURAL DISASTERS MAY ADVERSELY AFFECT OUR BUSINESS
    
 
    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 BILLING VENDOR MAY AFFECT THE TIMING OF OUR RECEIPT OF FUNDS
    
 
   
    We rely primarily on one vendor to produce all of our customer billings. If
this billing vendor for any reason were to encounter significant problems
affecting its ability to perform its billing functions for us, our ability to
generate billings to our customers would be materially impaired, until a new
arrangement could be established.
    
 
   
THE CONCERN OVER RADIO FREQUENCY EMISSIONS MAY AFFECT USE OF CELLULAR TELEPHONES
    
 
   
    Media reports have suggested that certain radio frequency emissions from
portable cellular telephones may be linked to cancer, and may interfere with
pacemakers and other medical devices. Concerns over radio frequency emissions
may have the effect of discouraging the use of cellular telephones, which could
have a material adverse effect on our business. On August 1, 1996, the FCC
released a report and order, which became effective in August 1996 as to mobile
and portable devices and in October 1997 for cellular transmitters, that updates
the guidelines and methods it uses for evaluating radio frequency emissions from
radio equipment, including cellular and PCS telephones and transmitting
facilities. We do not believe these guidelines will have a material impact on
its operations. While the FCC's rules impose more restrictive standards on radio
frequency emissions from lower power devices such as portable cellular
telephones, we believe, based on manufacturers' certifications, that all
cellular telephones currently provided by us to our customers, as well as our
transmitting facilities, comply with the FCC's standards. See
"Business--Regulation."
    
 
   
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 the operations or financial structure of the
Company 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.
 
                                       30
<PAGE>
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 sale or other
disposition of such shares of Preferred Stock. In the case of distributions of
additional 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 Preferred Stock. A holder would recognize gain to the
extent that 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 de minimis amount, the difference ("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 ("OID") 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. Moreover, there should be no net effect on the
holder's adjusted tax basis of the Preferred Stock as a result of the
constructive distribution if we have no current or accumulated earnings and
profits. 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 as to which the distribution is deemed
to have been made. See "Federal Income Tax Considerations to U.S.
Holders--Redemption Premium."
 
    Additional shares of Preferred Stock distributed on the 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 de minimis amount. Such redemption premium may differ
from that attributable to the shares of Preferred Stock. Therefore, any such
additional shares of the Preferred Stock distributed 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 the 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 distributed, 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 OID for U.S.
federal income tax purposes, unless under special rules for interest holidays
the amount of OID is treated as de minimis. If the Exchange Debenture has OID in
excess of the de minimis 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
 
                                       31
<PAGE>
discount obligations," in which case the Company's 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 to U.S. Holders."
 
   
POTENTIAL FAILURE OF COMPUTER SYSTEMS TO RECOGNIZE YEAR 2000 MAY ADVERSELY
  AFFECT OUR OPERATIONS
    
 
    The "Year 2000 Issue" is the result of the inability of some computer
programs to distinguish the year 1900 from the year 2000. Most computer programs
and operating systems were written using two digits to define the applicable
year rather than four digits. This means that any equipment containing computer
programs with time-sensitive software may recognize a date using "00" as the
year 1900 rather than the year 2000. In some instances this could result in
system failures, disruption in operations and possible inaccuracies of data.
 
    In April 1998, we established a multi-disciplined team to perform a Year
2000 impact analysis for us. 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 its 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. By the end of 1999, all of our automated systems and
services and those of Sygnet will be Year 2000 compliant.
 
    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 its business and
operational support applications. Those applications that have not been
outsourced to service providers have been deployed using packaged software from
outside vendors. We have also focused on evaluating software systems of pending
acquisitions. As a result, the remediation 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 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. We estimate total costs of approximately $0.8 million to
upgrade or replace those systems that are not Year 2000 compliant and will not
be upgraded through existing maintenance or service agreements. In addition, our
contingency plan for the Year 2000 is encompassed by a disaster recovery plan
for the business which will be in place by the end of the second quarter 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, we will conduct our own Year 2000
tests on mission critical systems as Year 2000 compliant versions are released
by vendors.
 
   
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
 
                                       32
<PAGE>
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
    
 
   
    - 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 description of our plans set forth herein, including our strategies,
planned capital expenditures, acquisitions and related financing, are
forward-looking statements made pursuant to the safe harbor provisions of the
Private Securities Litigation Reform Act of 1995. 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. Readers are cautioned not to place undue
 
                                       33
<PAGE>
reliance on these forward-looking statements which speak only as of the date
hereof. We do not intend to update or revise these forward-looking statements to
reflect events or circumstances after the date hereof including, without
limitation, changes in our business strategy or planned capital expenditures, or
to reflect the occurrence of unanticipated events.
 
                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
    An aggregate of 64,646 Old Shares were initially sold by Dobson 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 offered
and sold the Old Shares only to "qualified institutional buyers" (as defined in
Rule 144A) in compliance with Rule 144A. Subsequently and through January 15,
1999, 506 additional Old Shares have been issued as the payment of dividends on
the outstanding Preferred Stock.
 
   
    In connection with the sale of the Old Shares, the Company and the Initial
Purchaser entered into a Registration Rights Agreement dated as of December 23,
1998 (the "Registration Rights Agreement"), which requires the Company (i) to
cause the Old Shares to be registered under the Securities Act, or (ii) to file
with the Commission a registration statement under the Securities Act with
respect to an issue of New Shares of the Company identical in all material
respects to the Old Shares and use its best efforts to cause such registration
statement to become effective under the Securities Act and, upon the
effectiveness of that registration statement, to offer to the holders of the Old
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. A copy of the Registration Rights Agreement has been filed
as an exhibit to the Registration Statement of which this Prospectus is a part.
The Exchange Offer is being made pursuant to the Registration Rights Agreement
to satisfy the Company's obligations thereunder. The term "holder" with respect
to the Exchange Offer means any person in whose name Old Shares are registered
on the Company's books or any other person who has obtained a properly completed
stock power from the registered holder, or any person whose Old Shares are held
of record by The Depository Trust Company ("DTC") who desires to deliver such
Old Share by book-entry transfer at DTC.
    
 
    The Company has not requested, and does not intend to request, an
interpretation by the staff of the Commission with respect to whether the New
Shares issued pursuant to 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 Commission set
forth in no-action letters issued to third parties, the Company believes the New
Shares issued pursuant to the Exchange Offer in exchange for Old Shares may be
offered for resale, resold and otherwise transferred by any holder thereof
(other than broker-dealers, as set forth below, and any such holder that is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act) without compliance with the registration and prospectus delivery provisions
of the Securities Act, provided that such New Shares are acquired in the
ordinary course of such holder's business and that such holder has no
arrangement or understanding with any person to participate in the distribution
of such New 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 an affiliate of the Company may not rely upon such
interpretations by the staff of the Commission and, in the absence of an
exemption therefrom, must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any secondary resale
transaction. Failure to comply with such requirements in such instance may
result in such holder incurring liabilities under the Securities Act for which
the holder is not indemnified by the Company. Each broker-dealer (other than an
affiliate of the Company) that receives New Shares for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus meeting
the requirements of the Securities Act in connection with any resale of such New
Shares. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a
 
                                       34
<PAGE>
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. The Company has agreed that, for a period of 180
days after the Exchange Date, it will make the Prospectus available to any
broker-dealer for use in connection with any such resale. See "Plan of
Distribution."
 
    The Exchange Offer is not being made to, nor will the Company accept
surrenders for exchange from, holders of Old Shares in any jurisdiction in which
this Exchange Offer or the acceptance thereof would not be in compliance with
the securities or blue sky laws of such jurisdiction.
 
    By tendering in the Exchange Offer, each holder of Old Shares will represent
to the Company that, among other things, (i) the New Shares acquired pursuant to
the Exchange Offer are being obtained in the ordinary course of business of the
person receiving such New Shares, whether or not such person is the holder, (ii)
neither the holder of Old Shares nor any such other person has an arrangement or
understanding with any person to participate in the distribution of such New
Shares, (iii) if the holder is not a broker-dealer, or is a broker-dealer but
will not receive New Shares for its own account in exchange for Old Shares,
neither the holder nor any such other person is engaged in or intends to
participate in the distribution of such New Shares, and (iv) neither the holder
nor any such other person is an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act or, if such holder is an "affiliate," that
such holder will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable.
 
    Following the completion of the Exchange Offer, none of the shares of Senior
Preferred Stock will be entitled to the contingent increase in dividend rate
applicable to the Old Shares. Following the consummation of the Exchange Offer,
holders of Senior Preferred Stock will not 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--Consequences of the Exchange Offer on Non-Tendering Holders of
the Old Shares."
 
    Participation in the Exchange Offer is voluntary and holders should
carefully consider whether to accept. Holders of the Old Shares are urged to
consult their financial and tax advisors in making their own decisions on
whether to participate in the Exchange Offer.
 
TERMS OF THE EXCHANGE OFFER
 
    GENERAL.  Upon the terms and subject to the conditions set forth in this
Prospectus and in the Letter of Transmittal, the Company will accept any and all
Old Shares validly tendered and not withdrawn prior to 5:00 p.m., New York City
time, on the Expiration Date. The Company will issue one New Share in exchange
for each Old Share accepted in the Exchange Offer. Holders may tender some or
all of their Old Shares pursuant to 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 the transfer thereof. The New
Shares will be treated as a single class with any Old Shares that remain
outstanding. The Exchange Offer is not conditioned upon any minimum number of
Old Shares being tendered for exchange.
 
   
    As of February 12, 1999, 65,152 Old Shares were outstanding. This
Prospectus, together with the Letter of Transmittal, is being sent to all
registered holders.
    
 
    Holders of Old Shares 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. The Company intends 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 Commission thereunder. Old Shares which are not tendered for exchange in
the Exchange Offer will
 
                                       35
<PAGE>
remain outstanding and dividends thereon will continue to accrue, but such Old
Shares will not be entitled to any rights or benefits under the Registration
Rights Agreement.
 
    The Company will be deemed to have accepted validly tendered Old Shares
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
for the purposes of receiving the New Shares from the Company. If any tendered
Old Shares are not accepted for exchange because of an invalid tender, the
occurrence of certain other events set forth herein or otherwise, certificates
for any such unaccepted Old Shares will be returned, without expense, to the
tendering holder thereof as promptly as practicable after the Expiration Date.
 
    Holders who tender Old Shares in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Shares
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other than certain applicable taxes described below, in connection with the
Exchange Offer. See "--Fees and Expenses."
 
    EXPIRATION DATE; EXTENSIONS; AMENDMENTS.  The term "Expiration Date" shall
mean 5:00 p.m., New York City time, on         , 1999, unless the Company, in
its sole discretion, extends the Exchange Offer, in which case the term
"Expiration Date" shall mean the latest date and time to which the Exchange
Offer is extended. Although the Company has no current intention to extend the
Exchange Offer, the Company reserves the right to extend the Exchange Offer at
any time and from time to time by giving oral or written notice to the Exchange
Agent and by timely public announcement communicated, unless otherwise required
by applicable law or regulation, by making a release to the Dow Jones News
Service. During any extension of the Exchange Offer, all Old 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.
 
    The Company reserves the right, in its sole discretion, (i) 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" shall not have been satisfied, by giving oral or written
notice of such delay, extension or termination to the Exchange Agent, or (ii) to
amend the terms of the Exchange Offer in any manner. Any such delay in
acceptance, extension, termination or amendment will be followed as promptly as
practicable by oral or written notice thereof to the registered holders. If the
Exchange Offer is amended in any manner determined by the Company to constitute
a material change, the Company will promptly disclose such amendment by means of
a prospectus supplement that will be distributed to the registered holders, and
the Company will extend the Exchange Offer for a period of time, depending upon
the significance of the amendment and the manner of disclosure to the registered
holders, if the Exchange Offer would otherwise expire during such period.
 
    In all cases, issuance of the New Shares for Old Shares that are accepted
for exchange pursuant to the Exchange Offer will be made only after timely
receipt by the Exchange Agent of a properly completed and duly executed Letter
of Transmittal and all other required documents; provided, however, that the
Company reserves the absolute right to waive any conditions of the Exchange
Offer or defects or irregularities in the tender of Old 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 principal
amount 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.
 
    DIVIDENDS ON THE NEW SHARES.  Holders of Old Shares that are accepted for
exchange will not receive accrued dividends thereon at the time of exchange.
However, accrued but unpaid dividends on exchanged Old Shares (rounded to the
nearest whole share) will be paid in New Shares on the first dividend payment
date following consummation of the Exchange Offer.
 
                                       36
<PAGE>
    PROCEDURES FOR TENDERING OLD SHARES.  The tender to the Company of Old
Shares by a holder thereof pursuant to one of the procedures set forth below
will constitute an agreement between such holder and the Company in accordance
with the terms and subject to the conditions set forth herein and in the Letter
of Transmittal. A holder of the Old Shares may tender such Old Shares by (i)
properly completing and signing a Letter of Transmittal or a facsimile thereof
(all references in this Prospectus to a Letter of Transmittal shall be deemed to
include a facsimile thereof) and delivering the same, together with any
corresponding certificate or certificates representing the Old Shares being
tendered (if in certificated form) and any required signature guarantees, to the
Exchange Agent at its address set forth in the Letter of Transmittal on or prior
to the Expiration Date (or complying with the procedure for book-entry transfer
described below), or (ii) complying with the guaranteed delivery procedures
described below.
 
    If tendered Old Shares are registered in the name of the signer of the
Letter of Transmittal and the New Shares to be issued in exchange therefor are
to be issued (and any untendered Old Shares are to be reissued) in the name of
the registered holder (which term, for the purposes described herein, shall
include any participant in DTC (also referred to as a book-entry facility) whose
name appears on a security listing as the owner of Old Shares), the signature of
such signer need not be guaranteed. In any other case, the tendered Old Shares
must be endorsed or accompanied by written instruments of transfer in form
satisfactory to the Company and duly executed by the registered holder and the
signature on the endorsement or instrument of transfer must be guaranteed by an
eligible guarantor institution which is a member of one of the following
recognized signature guarantee programs (an "Eligible Institution"): (i) The
Securities Transfer Agents Medallion Program (STAMP), (ii) The New York Stock
Exchange Medallion Signature Program (MSF), or (iii) The Stock Exchange
Medallion Program (SEMP). If the New 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.
 
    THE METHOD OF DELIVERY OF OLD SHARES, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF
THE HOLDER. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OLD SHARES SHOULD BE
SENT TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.
 
    The Company understands that the Exchange Agent has confirmed with DTC that
any financial institution that is a participant in DTC's system may utilize
DTC's Automated Tender Offer Program ("ATOP") to tender Old Shares. The Company
further understands that the Exchange Agent will request, within two business
days after the date the Exchange Offer commences, that DTC establish an account
with respect to the Old 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 (as defined in the next sentence), and any other
documents required by the Letter of Transmittal. The term "Agent's Message"
means a message, transmitted by DTC and received by the Exchange Agent and
forming part of Book-Entry Confirmation, which states that DTC has received an
express acknowledgment from a participant tendering Old Shares which are the
subject of such Book-Entry Confirmation and that such participant has received
and agrees to be bound by the terms of the Letter of Transmittal and that the
Company may enforce such agreement against such participant.
 
                                       37
<PAGE>
    A tender will be deemed to have been received as of the date when (i) the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old 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 (ii) a Notice of Guaranteed Delivery or letter, telegram or
facsimile transmission to similar effect (as provided below) from an Eligible
Institution is received by the Exchange Agent. Issuances of New Shares in
exchange for Old Shares tendered pursuant to a Notice of Guaranteed Delivery or
letter, telegram or facsimile transmission to similar effect (as provided below)
by an Eligible Institution will be made only against submission of a duly signed
Letter of Transmittal (and any other required documents) and deposit of the
tendered Old Shares.
 
    All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of Old Shares will be
determined by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all tenders not in proper
form or the acceptance for exchange of which may, in the opinion of the
Company's counsel, be unlawful. The Company also reserves the absolute right to
waive any of the conditions of the Exchange Offer or any defect or irregularity
in the tender of any Old Shares. None of the Company, the Exchange Agent or any
other person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification. Any Old 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, the Company reserves the right in its sole discretion (a) to
purchase or make offers for any Old Shares that remain outstanding subsequent to
the Expiration Date, and (b) 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 the holder desires 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, a tender may be
effected if the Exchange Agent has received at its office, on or prior to the
Expiration Date, a letter, telegram or facsimile transmission from an Eligible
Institution setting forth the name and address of the tendering holder, the
name(s) in which the Old Shares are registered and the certificate number(s) of
the Old Shares to be tendered, and stating that the tender is being made thereby
and guaranteeing that, within three New York Stock Exchange trading days after
the date of execution of such letter, telegram or facsimile transmission by the
Eligible Institution, such Old 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), the Company may, at its option, reject the
tender. Copies of a Notice of Guaranteed Delivery which may be used by Eligible
Institutions for the purposes described in this paragraph are available from the
Exchange Agent.
 
    TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL.  The Letter of
Transmittal contains, among other things, the following terms and conditions,
which are part of the Exchange Offer.
 
    The party tendering Old Shares for exchange (the "Transferor") exchanges,
assigns and transfers the Old Shares to the Company 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
 
                                       38
<PAGE>
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, the
Company 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 the Company 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 the Company
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 (i) specify the name of
the person having deposited the Old Shares to be withdrawn (the "Depositor"),
(ii) identify the Old Shares to be withdrawn (including the certificate number
or numbers and principal amount of such Old Shares), (iii) contain a statement
that such holder is withdrawing its election to have such Old Shares exchanged,
(iv) 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 (v) 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
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by the Company, whose determination shall be
final and binding on all parties. Any Old 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, the Company shall not be 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:
 
        (a) any statute, rule or regulation shall have been enacted, or any
    action shall have been taken by any court or governmental authority which,
    in the reasonable judgment of the Company, would prohibit, restrict or
    otherwise render illegal consummation of the Exchange Offer; or
 
        (b) any change, or any development involving a prospective change, in
    the business or financial affairs of the Company or any of its subsidiaries
    has occurred which, in the sole judgment of the Company, might materially
    impair the ability of the Company to proceed with the Exchange Offer or
    materially impair the contemplated benefits of the Exchange Offer to the
    Company; or
 
                                       39
<PAGE>
        (c) there shall occur a change in the current interpretations by the
    staff of the Commission which, in the Company's reasonable judgment, might
    materially impair the Company's ability to proceed with the Exchange Offer.
 
    If the Company determines in its sole discretion that any of the above
conditions are not satisfied, the Company may (i) refuse to accept any Old
Shares and return all tendered Old Shares to the tendering holders, (ii) 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 (see
"--Terms of the Exchange Offer--Withdrawal of Tenders of Old Shares"), or (iii)
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, the Company will promptly
disclose such waiver by means of a prospectus supplement that will be
distributed to the registered holders, and the Company will extend the Exchange
Offer for a period of time, depending upon the significance of the waiver and
the manner of disclosure to the registered holders, if the Exchange Offer would
otherwise expire during such period.

FEES AND EXPENSES
 
    The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telecopy, telephone or in person by officers and regular
employees of the Company and its affiliates. No additional compensation will be
paid to any such officers and employees who engage in soliciting tenders.
 
    The Company has not retained any dealer-manager or other soliciting agent in
connection with the Exchange Offer and will not make any payments to brokers,
dealers or others soliciting acceptance of the Exchange Offer. The Company,
however, will pay the Exchange Agent reasonable and customary fees for its
services and will reimburse it for its reasonable out-of-pocket expenses in
connection therewith. The Company may also pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding copies of this Prospectus, the Letter of
Transmittal and related documents to the beneficial owners of the Old Shares and
in handling or forwarding tenders for exchange.
 
                                       40
<PAGE>
    The expenses to be incurred in connection with the Exchange Offer will be
paid by the Company. Such expenses include fees and expenses of the Exchange
Agent and transfer agent and registrar, accounting and legal fees and printing
costs, among others.
 
    The Company will pay all transfer taxes, if any, applicable to the exchange
of the Old Shares pursuant to 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 pursuant to 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 (i) to
the Company or any subsidiary thereof, (ii) to a qualified institutional buyer
in compliance with Rule 144A, (iii) to an institutional accredited investor
that, prior to such transfer, furnishes to the Trustee a signed letter
containing certain representations and agreements relating to the restrictions
on transfer of the Old Shares (the form of which letter can be obtained from the
Trustee) and, if such transfer is in respect of an aggregate principal amount of
Old Shares at the time of transfer of less than $100,000, an opinion of counsel
acceptable to the Company that such transfer is in compliance with the
Securities Act, (iv) outside the United States in compliance with Rule 904 under
the Securities Act, (v) pursuant to the exemption from registration provided by
Rule 144 under the Securities Act (if available), or (vi) 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 Senior Preferred Stock will
have no further registration rights under the Registration Rights Agreement and
will not be entitled to the contingent increase in the dividend rate applicable
to the Old Shares.
 
    FIRPTA TREATMENT
 
    At present, the Company believes that it is 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 the Company's expectation for the future will not
change. If the Company is found to be a U.S. real property holding company, then
a Non-United States Holder of Senior Preferred Stock may be subject to U.S.
federal income tax in respect of gain realized on the sale or other disposition
of the Senior 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 Senior 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 Senior Preferred Stock at any time
during the five-year period (or shorter holding period for the Senior 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 Senior 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.
Under recently-finalized Treasury regulations, the certification
 
                                       41
<PAGE>
requirements were modified in certain respects for payments made on or after
January 1, 1999. Prospective Non-United States Holders should consult their own
tax advisors regarding the application of the new Treasury regulations to an
investment in the Senior Preferred Stock and Exchange Debentures.
 
    THE FOREGOING SUMMARY DOES NOT DISCUSS ALL ASPECTS OF U.S. FEDERAL INCOME
TAXATION THAT MAY BE RELEVANT TO A PARTICULAR HOLDER OF SENIOR PREFERRED STOCK
AND EXCHANGE DEBENTURES IN LIGHT OF ITS PARTICULAR CIRCUMSTANCES AND INCOME TAX
SITUATION. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISOR AS TO THE SPECIFIC TAX
CONSEQUENCES THAT WOULD RESULT FROM THEIR PURCHASE, OWNERSHIP AND DISPOSITION OF
THE SENIOR 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 historical consolidated financial
data of Dobson Communications Corporation as of and for each of the five years
ended December 31, 1997 and as of and for the nine months ended September 30,
1997 and 1998. The consolidated financial data as of and for each of the years
in the period 1993 to 1997 have been derived from the Company's consolidated
financial statements which have been audited by Arthur Andersen LLP. The
consolidated financial data as of and for the nine months ended September 30,
1997 and 1998 have been derived from the unaudited financial statements of the
Company which, in the opinion of management have been prepared on the same basis
as the Company's audited consolidated financial statements and include all
adjustments (which consist only of normal recurring adjustments) necessary for a
fair presentation of the information set forth therein. Operating results for
the nine months ended September 30, 1998 are not necessarily indicative of the
results that may be expected for the full year. Acquisitions made by the Company
during 1996, 1997 and 1998 materially affect the comparability of data from one
period to another. The data should be read in conjunction with "Use of
Proceeds," "Pro Forma Condensed Consolidated Financial Data," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
the Company's financial statements and the related notes thereto included
elsewhere in this Prospectus.

 (5) Reflects minority interests in partnerships in which the Company owns the
     majority interests.
 
 (6) Extraordinary items reflect gain or (loss) related to early extinguishment
     of debt.
 
 (7) Adjusted EBITDA represents earnings before interest expense, income taxes,
     depreciation, amortization, extraordinary items and changes in accounting
     principles. Adjusted EBITDA is provided because it is a measure commonly
     used in the telecommunications industry to determine a company's ability to
     incur or service debt. Adjusted EBITDA is not derived pursuant to generally
     accepted accounting principles and should not be construed as an
     alternative to net income, as a measure of performance, or to cash flows,
     as a measure of liquidity. The calculation of Adjusted EBITDA does not
     include the Company's commitments for capital expenditures or payments of
     debts and should not be deemed to represent funds available to the Company.
 
 (8) Includes Adjusted EBITDA attributable to minority interests in subsidiaries
     in which the Company owns a majority interest. The portion of Adjusted
     EBITDA attributable to minority interests was $.9 million, $1.5 million,
     $2.0 million, $2.3 million, $2.9 million, $2.0 million and $3.7 million for
     the years ended December 31, 1993, 1994, 1995, 1996 and 1997 and for the
     nine months ended September 30, 1997 and 1998, respectively.
 
 (9) 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, by $11.2 million for
     the nine months ended September 30, 1997 and by $49.8 million for the nine
     months ended September 30, 1998. "Earnings" is defined as earnings from
     continuing operations 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.
 
 (10) Determined by dividing the Company's total ending cellular subscribers for
      the period by the estimated total Pops covered by applicable FCC cellular
      licenses.
 
 (11) Churn means the number of cellular subscriber cancellations per period as
      a percentage of the weighted average total cellular subscribers during
      such period. Churn is stated as the average monthly churn rate for the
      period.
 
 (12) Excludes roaming and equipment revenue.
 
 (13) Determined by dividing cellular marketing and selling costs by the gross
      cellular subscribers added during each period. Cellular marketing and
      selling costs represent selling expenses and losses incurred on equipment
      sales.

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

1997 Acquisitions, the 1998 Acquisition and the Sygnet Acquisition have been
accounted for using the purchase method of accounting.
 
    The unaudited pro forma condensed consolidated financial statements have
been prepared on the basis of certain assumptions that the Company believes are

thereto should be read in conjunction with "Selected Consolidated Financial and

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
                      CONSOLIDATED STATEMENT OF OPERATIONS
                      NINE MONTHS ENDED SEPTEMBER 30, 1998
 
(1) To reflect the results of operations for California 4 for the three month
    period in 1998 during which the property was not owned by the Company.
 
(2) To reclassify certain operating revenues and expenses to conform with the
    Company's historical presentation.
 
(3) To reflect the additional depreciation and amortization resulting from the
    allocation of purchase price to property and equipment, cellular license
    acquisition costs and intangible assets. Property and equipment is being
    depreciated over two to ten years, cellular license acquisition costs over
    15 years and intangible assets over five to ten years. The 15 year period
    used for cellular license acquisition costs is based primarily on the
    Company's internal analysis of the recovery period for its cellular
    investments, which indicates that such costs will be recovered through
    operations over a period of not more than 15 years. Other factors considered
    include the competitive nature of the cellular industry, the rate of
    technological change and risk of obsolescence, and the specific terms and
    characteristics of the licenses. See "Risk Factors--Competition" and
    "--Rapid Technological Changes."
 
(4) To reflect (i) the $.7 million of interest expense relating to the $28.4
    million of indebtedness incurred under the DCOC Facility in connection with
    the California 4 Acquisition (assuming an interest rate of 9.0% per annum)
    and (ii) the elimination of $.3 million of interest expense associated with
    the indebtedness of California 4 which was not assumed by the Company.
 
(5) To reflect (i) the elimination of $21.6 million of interest expense
    associated with the Sygnet Notes and Sygnet's existing bank facility which
    will be repaid by the Company as part of the Sygnet Acquisition, (ii) $18.4
    million of interest expense relating to the $200.0 million of the
    Dobson/Sygnet Notes, (iii) $25.0 million of interest expense relating to the
    borrowings under the New Credit Facilities (assuming a weighted average rate
    of 8.38%), (iv) $.1 million of interest expense relating to the unused
    principal amounts of the New Credit Facilities (assuming a commitment fee of
    .5%), (v) $.6 million of amortization of deferred financing costs relating
    to the estimated $8.2 million of debt issuance costs incurred in connection
    with the offering of the Dobson/Sygnet Notes, (vi) $1.1 million of
    amortization of deferred financing costs relating to the estimated $12.6
    million of debt issuance costs incurred in connection with the New Credit
    Facilities, (vii) $1.1 million of interest relating to the $17.5 million of
    borrowings under the Dobson Tower Facility, (viii) the elimination of $.3
    million of interest related to the $25.0 million borrowed under the DOC
    Facility to pay the initial deposit for the Sygnet Acquisition and (ix) $1.1
    million of interest expense related to the $16.2 million of borrowings under
    existing credit facilities.
 
(6) To reflect an adjustment to income tax expense for the effects of the 1998
    Transactions, assuming a 38% effective tax rate.
 
(7) To reflect dividends on the Senior Preferred Stock, including, the
    amortization of the issuance costs with respect thereto.
 
(8) To reflect dividends on the Preferred Stock, including the amortization of
    the issuance costs and discount with respect thereto and to reflect the
    dividends on the Class D, Class F and Class G Preferred Stock, assuming
    dividend rates of 15%, 16% and 16%, respectively, and does not reflect
    dividends on the preferred stock to be issued by Dobson Tower or any
    amortization of discount on the Class F Preferred Stock resulting from any
    value that may be attributed to the warrants granted to the purchasers of
    the Class F Preferred Stock.

    investments, which indicates that such costs will be recovered through
    operations over a period of not more than 15 years. Other factors considered
    include the competitive nature of the cellular industry, the rate of

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    The Company is a leading provider of rural cellular telephone services.
Since it commenced providing cellular services in 1990 in Oklahoma and the Texas
Panhandle, the Company has rapidly expanded its cellular operations with an
acquisition strategy targeting underdeveloped rural and suburban areas which
have a significant number of potential customers with substantial needs for
cellular communications. At September 30, 1998, the Company's cellular systems
covered 2.8 million Pops in Arizona, California, Kansas, Maryland, Missouri,
Oklahoma, Pennsylvania and Texas. On December 23, 1998 the Company acquired
Sygnet for $337.5 million in cash. The Company recently entered into an
agreement to acquire the FCC license for, and certain assets related to,
Maryland 1 RSA for $9.1 million in cash, subject to adjustment.
 
    Sygnet owns and operates cellular telephone systems serving a large cluster
of properties with approximately 2.4 million Pops and 166,886 subscribers
located in northeastern Ohio, western Pennsylvania and western New York.
Sygnet's cellular systems are located in Youngstown, Ohio and Erie,
Pennsylvania, and in primarily rural and suburban areas between the Cleveland,
Akron-Canton, Pittsburgh, Buffalo and Rochester metropolitan areas.
 
   
    The following discussion and analysis is of the historical financial
condition and results of operation of the Company and Sygnet and should be read
in conjunction with the Company's and Sygnet's consolidated financial statements
and the notes thereto appearing elsewhere in this Prospectus.
    
 
ACQUISITIONS
 
    The Company continually evaluates opportunities to acquire additional
wireless systems. The following table sets forth the cellular markets and
systems acquired and to be acquired by the Company since 1995 (ownership in
parentheses if not 100% owned by the Company):

REVENUE
 
    The cellular revenues of the Company and Sygnet 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. The Company
believes that the impact of this trend will be mitigated by increases in the
number of cellular telecommunications subscribers and the number of minutes of
usage per subscriber. There has also been a broad trend in the cellular
telecommunications industry of declining average revenue per subscriber. The
Company believes that the downward trend is primarily the result of the addition
of new lower usage customers who utilize cellular services for personal
convenience, security or as a backup for their traditional landline telephone.
Although the Company has experienced a decline in average revenue per
subscriber, the Company has introduced new services, such as voice mail and call
forwarding. In addition, Sygnet has introduced new pricing plans which have
increased revenue and encouraged additional usage to a limited extent.
 
    Roaming accounted for 39.4% and 47.7% of the Company's cellular revenue and
31.5% and 32.2% of Sygnet's revenues for the year ended December 31, 1997 and
the nine months ended September 30, 1998. On a pro forma basis after giving
effect to the Sygnet Acquisition, for the year ended December 31, 1997 and for
the nine months ended September 30, 1998 roaming would have accounted for 36.7%
and 39.1%, respectively, of the Company's revenue from its cellular operations.
While the industry trend is to reduce roaming rates, the Company believes that
its roaming rates and those of Sygnet are generally lower than rates offered by
others in or near the Company's or Sygnet's systems and that such lower roaming
rates mitigate against this trend; however, there can be no assurance that such
trend will not materially impact it in the future. The Company's roaming yield
(roamer service revenue, which includes airtime, toll charges and surcharges,
divided by roaming minutes of use) was $.70, $.75, $.70 and $.72 per minute
(excludes Arizona 5 for 1997, for which the roaming minutes of use were not
available) for the years ended December 31, 1995, 1996 and 1997 and for the nine
months ended September 30, 1998, respectively. Sygnet's roaming yield for the
same periods was $.57, $.55, $.58 and $.57, respectively.
 
    Included in the Sygnet roaming revenue for the years ended December 31,
1995, 1996 and 1997 and for the nine months ended September 30, 1997 and
September 30, 1998, respectively, was $.1 million, $.9 million, $3.6 million,
$2.5 million and $4.0 million attributable to Sygnet customers roaming out of
their home areas but in other Sygnet markets.
 
    The Company's overall cellular penetration rates decreased in 1996 and 1997
compared to 1995 due to the 1996 acquisition of Kansas/Missouri and the 1997
acquisitions of the Maryland properties, which operations, when acquired, had
lower overall penetration rates than the Company's existing properties. However,
penetration rates increased in the nine months ended September 30, 1998 compared
to the nine months ended September 30, 1997 as a result of acquisitions and
incremental penetration gain in existing markets. Sygnet's overall cellular
penetration rates increased in 1997 compared to 1996 and in the nine months
ended September 30, 1998 compared to the nine months ended September 30, 1997 as
a result of internal growth. The Company believes that as its 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, the Company 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, the Company
has incurred, and expects to continue to incur, losses on equipment sales, which
have resulted in increased marketing and selling costs per gross additional
subscriber. While the Company expects to continue these discounts and
promotions, the Company believes that the use of such promotions will result in
increased revenue from increases in the number of wireless subscribers.

COSTS AND EXPENSES
 
    The Company's and Sygnet's primary operating expense categories include cost
of service, cost of equipment, marketing and selling, general and administrative
and depreciation and amortization.
 
    The Company's cost of service consists primarily of costs to operate and
maintain the Company's facilities utilized in providing service to customers and
amounts paid to third-party cellular providers for providing service to the
Company's subscribers.
 
    Sygnet's cost of service consists primarily of costs associated with
billing, amounts paid for interconnection and call delivery and amounts paid to
third-party cellular providers for providing service to Sygnet's subscribers
when roaming, offset by the amount billed to Sygnet's subscribers.
 
    The Company's and Sygnet's cost of equipment represents the cost associated
with telephone equipment and accessories sold to customers. In recent years, the
Company and Sygnet, as well as other cellular companies, have increased the use
of discounts on phone equipment and free phone promotions, as competition
between service providers has intensified. As a result, the Company and Sygnet
have incurred, and the Company expects to continue to incur, losses on equipment
sales, which have affected marketing and selling costs per gross additional
cellular subscriber. While the Company expects to continue these discounts and
promotions, the Company believes that the use of such promotions will lead to
increased revenue from increases in the number of cellular subscribers.
 
    The Company's 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.
 
    Sygnet's marketing and selling costs primarily consist of advertising costs
and compensation paid to sales personnel and independent agents and retail store
operations' costs. Commissions are paid to direct sales personnel primarily for
the amount of new business generated. Independent sales agents receive
commissions for generating new sales and ongoing sales to existing customers.
 
    The Company's general and administrative costs include all infrastructure
costs such as customer support, billing, collections, and corporate
administration.
 
    Sygnet's general and administrative costs include all infrastructure costs
such as customer support, collections, corporate administration, costs to
maintain and operate cell sites and customer retention costs.
 
   
    The size and scope of the Company's cellular operations increased
substantially as a result of acquisitions in 1996, 1997 and 1998, and will
increase further upon consummation of the Sygnet Acquisition. See "Pro Forma
Condensed Consolidated Financial Data." On a pro forma basis after giving effect
to the Sygnet Acquisition, the Texas 10 Acquisition and the Maryland 1
Acquisition, the Company would have had 347,306 subscribers at September 30,
1998. Although the Company's Adjusted EBITDA has increased as a result of
acquisitions made to date and will increase as a result of the Sygnet
Acquisition, the increased amortization and interest expense and dividends
associated with the Senior Notes, additional bank borrowings and Senior
Preferred Stock resulted in increased losses in 1997 and the first nine months
of 1998, which are expected to increase as a result of the Dobson/Sygnet Notes,
the offering of the Preferred Stock and the New Credit Facilities and continue
until the Company expands the acquired systems and increases its subscriber
base. As a result of the recent acquisitions, the comparability of the
historical results of operations have been affected for the periods discussed
and such results may not be indicative of future performance.

    Service revenue increased $21.3 million, or 80.3%, to $47.8 million in the
first nine months of 1998 from $26.5 million in the same period of 1997. Of the
increase, $16.4 million was attributable to the acquisitions. The remaining $4.9
million was primarily attributable to increased penetration and usage in the
Central and Eastern Regions. The Company's subscriber base increased 91.4% to
163,020 at September 30, 1998 from 85,185 at September 30, 1997. Approximately
54,417 subscribers were added since September 30, 1997 as a result of the
acquisitions of Arizona 5 and the 1998 Acquisitions. The Company's average
monthly service revenue per subscriber decreased 3.7% to $39.58 for the nine
months ended September 30, 1998 from $41.08 for the comparable period in 1997
due to the addition of new lower rate subscribers in the East Region and
competitive market pressures.
 
    Roaming revenue increased $28.1 million, or 158.2%, to $45.9 million in the
first nine months of 1998 from $17.8 million for the comparable period of 1997.
Of the increase, $24.1 million was attributable to the 1997 and 1998
acquisitions. The remaining $4.0 million was primarily attributable to increased
roaming minutes in the Central and Eastern Regions due to expanded coverage
areas and increased usage in these markets.
 
    Equipment sales of $2.5 million in the first nine months of 1998 represented
an increase of $1.8 million, or 238%, from $0.7 million in the same period of
1997, as the Company sold more equipment during the first nine months of 1998.

    COST OF SERVICE.  For the nine month period ended September 30, 1998, the
total cost of service increased $11.7 million, or 106.8%, to $22.6 million from
$10.9 million for the comparable period in 1997. Of the increase, $10.0 million
was attributable to 1997 and 1998 Acquisitions. The remaining $1.7 million was
primarily attributable to increased subscribers and minutes of use in the
Central and Eastern Regions and expanded use of rerating agreements with
providers adjacent to the Company's markets. As a percentage of service and
roaming revenue, cost of wireless service decreased slightly to 24.1% in the
first nine months of 1998 from 24.7% in the comparable period of 1997.
 
    COST OF EQUIPMENT.  For the nine month period ended September 30, 1998, cost
of equipment increased $2.4 million, or 82.3%, to $5.2 million during the first
nine months of 1998 from $2.8 million in the first nine months of 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 $8.0
million, or 114.9%, to $14.9 million in the first nine months of 1998 from $6.9
million in the comparable period of 1997. As a percentage of total operating
revenue, marketing and selling costs increased to 15.4% in the first nine months
of 1998 from 15.1% in the same period of 1997. The increase was primarily due to
the higher level of subscribers added period to period. Gross subscribers added
in the first nine months of 1998 was 48,882. The number of gross subscribers
added in the first nine months of 1997 was 22,273.
 
    GENERAL AND ADMINISTRATIVE COSTS.  For the nine month period ended September
30, 1998, general and administrative costs increased $8.1 million, or 99.3%, to
$16.2 million from $8.1 million for the same period in 1997. As a percentage of
total operating revenue, general and administrative costs decreased to 16.8% in
the first nine months of 1998 from 17.8% in the comparable period of 1997. The
increase was primarily due to increased billing costs as a result of the growth
in subscribers, the 1997 and 1998 Acquisitions and increased salary costs
resulting from additional personnel. The decrease as a percentage of total
operating revenue is a result of the Company's strategy to integrate new
operations in its existing management structure and a reduction in the Company's
uncollectible rate.
 
    DEPRECIATION AND AMORTIZATION EXPENSE.  For the nine month period ended
September 30, 1998, depreciation and amortization expense increased $17.8
million, or 148.8% to $29.7 million in the first nine months of 1998 from $11.9
million in the same period of 1997. Depreciation and amortization of assets
acquired in acquisitions accounted for $17.7 million of the increase in the
first nine months of 1998 compared to the same period of 1997.
 
    INTEREST EXPENSE.  For the first nine months of 1998, interest expense
increased $7.3 million, or 41.9%, to $25.0 million from $17.7 million in the
comparable period of 1997. The increase was primarily a result of increased
borrowings in the first nine months of 1998 to finance the Company's
acquisitions.
 
    OTHER INCOME (EXPENSE), NET.  For the nine months ended September 30, 1998,
other income increased $1.4 million, or 78.1%, to $3.3 million from $1.9 million
in the first nine months of 1997. Of the increase, $1.2 million was attributable
to increased interest income in 1998. In 1998, the Company 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 1997 and 1998, the Company incurred an
extraordinary pretax loss of approximately $2.3 million and $3.3 million,
respectively, as a result of writing off previously capitalized financing costs
associated with revolving credit facilities that were refinanced in February
1997 and March 1998.
 
    YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
    OPERATING REVENUE.  For the year ended December 31, 1997, total operating

    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 the acquisition 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 was primarily attributable to
increased penetration and usage in the Central Region. The Company's 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 the acquisition of the
East Maryland and West Maryland markets. The Company's 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.
 
    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 the acquisition 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 the Company sold more equipment in 1997.
 
    COST OF SERVICE.  For the year ended December 31, 1997, the 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 the acquisition 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, the 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 sold due to the growth
in subscribers.
 
    MARKETING AND SELLING COSTS.  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. Gross subscribers added in 1997 was 33,354 with subscribers added in the
Eastern Region and in Arizona 5 since their acquisitions making up 16,469 and
1,307, respectively, of the gross subscribers added. The number of gross
subscribers added in 1996 was 11,970. As a percentage of 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,
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. The increase was
primarily due to increased billing costs as a result of the growth in wireless
subscribers, the 1997 Acquisitions, the inclusion of the 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 is a result of
additional personnel necessary to support the Company's expanded operations.
 
    DEPRECIATION AND AMORTIZATION EXPENSE.  For the year ended December 31,
1997, 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
as a result of the amortization of assets acquired in the acquisition 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
was primarily the result of increased borrowings to finance the acquisitions of
the Maryland and Arizona properties.
 
    OTHER INCOME (EXPENSE), NET.  For the year ended December 31, 1997, 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 was primarily a result of interest earned on securities
purchased which were pledged to secure payment of the first four semi-annual
interest payments on the Senior Notes.
 
    EXTRAORDINARY EXPENSE.  In 1997 and 1996, the Company 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 was refinanced in February 1997
and March 1996.
 
    YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
    OPERATING REVENUE.  For the year ended December 31, 1996, total operating
revenue increased $7.2 million, or 36.9%, to $26.9 million from $19.7 million in
1995. Total service, roaming and equipment revenue represented 65.3%, 29.1% and
2.5% of total operating revenue, respectively, in 1996 and 70.9%, 22.2% and 3.4%
of total operating revenue, respectively, in 1995.
 
    The following table sets forth the components of the Company's revenue for
the periods indicated:

</TABLE>
 
    Service revenue increased $3.6 million, or 26.1%, to $17.6 million in 1996
from $14.0 million in 1995. Of the $3.6 million increase, $2.5 million was
attributable to increased penetration and usage in Oklahoma and in the Texas
Panhandle and $1.1 million was attributable to the acquisition of the
Kansas/Missouri markets in March 1996. The Company's subscriber base increased
27.6% to 33,955 at December 31, 1996, from 26,614 at December 31, 1995, of which
58.6% (4,301 subscribers) of the increase was attributable to
 
                                       63
<PAGE>
increased penetration in Oklahoma and the Texas Panhandle. However, the
Company's average monthly service revenue per subscriber decreased 3.4% to
$48.31 for the year ended December 31, 1996 from $50.00 for the year ended
December 31, 1995 due to competitive market pressures and the addition of new
lower usage subscribers.
 
    Roaming revenue increased $3.5 million, or 79.7%, to $7.9 million in 1996
from $4.4 million in 1995. Of the $3.5 million increase, $1.9 million, or 54.3%,
was the result of the inclusion of the Kansas/Missouri markets with roaming
minutes of use totaling 1.3 million from the acquisition date in March 1996 to
December 31, 1996. The remaining $1.6 million of the increase, or 45.7%,
resulted from a 44.9% increase in roaming minutes of use in 1996 in Oklahoma and
the Texas Panhandle due to improved coverage areas and an increase in minutes of
use.
 
    Equipment sales of $0.7 million in 1996 represented a slight decrease over
1995. Although the Company sold more equipment during the year ended December
31, 1996, the Company increased its use of discounted equipment and free phone
promotions with the signing of one-year service contracts.
 
    COST OF SERVICE.  For the year ended December 31, 1996, the total cost of
service increased $1.4 million, or 31.5%, to $6.1 million from $4.7 million in
1995. Of the increase, $1.0 million was attributable to the inclusion of the
Kansas and Missouri properties from March 1996. The remaining increase primarily
was the result of roaming agreements entered into by the Company in 1995 with
eleven other carriers in Texas and Oklahoma to expand its home rate coverage.
Cost of wireless service decreased as a percentage of service and roaming
revenue to 24.0% for the year ended December 31, 1996 from 25.4% for 1995.
 
    COST OF EQUIPMENT.  For the year ended December 31, 1996, the total cost of
equipment increased $0.6 million, or 27.8%, to 2.6 million from $2.0 million in
1995. The increase resulted primarily from increases in the volume of equipment
sales due to the growth of subscribers during 1996, partially offset by a
decrease in equipment costs.
 
    MARKETING AND SELLING COSTS.  Marketing and selling costs increased $1.4
million, or 43.8%, to $4.5 million in 1996 from $3.1 million in 1995. The
increase was primarily due to the higher level of wireless subscribers added
period to period. Gross subscribers added for the year ended December 31, 1996
was 11,970 with the Kansas/Missouri markets making up 1,511 of the gross
subscribers added. The gross number of subscribers added in 1995 was 9,653. As a
percentage of total operating revenue, marketing and selling costs increased to
16.6% in 1996 from 15.8% in 1995.
 
    GENERAL AND ADMINISTRATIVE COSTS.  For the year ended December 31, 1996,
general and administrative costs increased $0.9 million, or 28.5%, to $3.9
million from $3.0 million for 1995. The increase was primarily due to increased
billing costs as a result of the growth in subscribers, the inclusion of the
Kansas/ Missouri markets from March 1996 and increased salary costs resulting
from additional personnel in its wireless and fiber operations. General and
administrative costs decreased as a percentage of the Company's total revenues
to 14.5% in 1996 from 15.4% in 1995.
 
    DEPRECIATION AND AMORTIZATION EXPENSE.  For the year ended December 31,
1996, depreciation and amortization expense increased $2.7 million to $5.2
million from $2.5 million in 1995. Approximately $1.2 million of the increase
was the result of the amortization of the licenses acquired in the Kansas/
Missouri markets, with the remainder due primarily to the increase in equipment
in the Company's business.
 
    INTEREST EXPENSE.  For the year ended December 31, 1996, interest expense
increased $2.4 million to $4.3 million from $1.9 million in 1995. The increase
was primarily a result of increased borrowings to finance the Kansas/Missouri
acquisition.
 
    OTHER INCOME (EXPENSE), NET.  For the year ended December 31, 1996, other
income (expense), net decreased $1.3 million to $(1.5) million from $(0.2)
million in 1995 primarily as a result of a $1.7 million
 
                                       64
<PAGE>
loss on the disposal of two mobile telecommunications switching offices made in
connection with system upgrades in Oklahoma and the Texas Panhandle.
 
    EXTRAORDINARY EXPENSE.  For the year ended December 31, 1996, the Company
incurred a pretax loss of approximately $.9 million as a result of writing off
previously capitalized financing costs associated with a revolving credit
facility that was refinanced in March 1996.
 
RESULTS OF OPERATIONS--SYGNET
 
    Sygnet's operating results have been significantly affected as a result of
the Horizon Acquisition in October 1996 and the Erie Acquisition in September
1995. The systems acquired for $252.9 million in the Horizon Acquisition serve
contiguous markets representing approximately 1.4 million Pops in western
Pennsylvania and New York. The systems acquired in the Erie Acquisition for
$42.5 million represent approximately 282,300 Pops.
 
    NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO NINE MONTHS ENDED SEPTEMBER
     30, 1997
 
    REVENUE.  For the nine months ended September 30, 1998, Sygnet's total
revenue increased 22.6% to $76.9 million, from $62.8 million in the first nine
months of 1997. The growth in revenue was the result of continued growth of the
subscriber base and increased roaming revenue generated by additional usage.
 
    Subscriber revenue grew 21.3% to $46.7 million for the nine months ended
September 30, 1998 from $38.5 million in the comparable period in 1997 mainly as
a result of continued subscriber growth, despite a decline in average revenue
per subscriber. Sygnet's number of subscribers increased by 28.2% to 166,886 at
September 30, 1998 from 130,146 at September 30, 1997 due to internal growth. On
a per subscriber basis, average monthly subscriber revenue per subscriber
declined by 6.8% to $33.85 for the nine months ended September 30, 1998 from
$36.33 during the comparable period in 1997. This was due to competitive market
pressures, continuing promotional activity and the changing mix of subscribers
reflecting increasing levels of subscribers who purchase less expensive rate
plans that include packaged minutes of use.
 
    Roamer revenue grew 24.6% to $24.8 million during the nine months ended
September 30, 1998 compared to $19.9 million in the comparable period in 1997.
This increase was mainly a result of increased roaming traffic throughout all of
Sygnet's systems which more than offset the decline in roaming revenue per
minute of use. Roaming minutes of use increased by 30.5% to 43.6 million for the
nine months ended September 30, 1998 from 33.4 million for the comparable period
in 1997. Roaming revenue per minute, including toll, for the nine months ended
September 30, 1998 decreased to $0.57 from $0.59 for the comparable period in
1997. This decrease was mainly a result of increased intrasystem roaming traffic
that is priced lower than other roaming traffic.
 
    Equipment sales revenue increased 39.4% to $4.3 million for the nine months
ended September 30, 1998 from $3.1 million in the comparable period in 1997.
This increase was due mainly to an increased number of telephones and
accessories sold to new customers as well as from additional sales of equipment
to existing customers for retention purposes for which credits are given on the
sales price and reflected in general and administrative costs.
 
    COST OF SERVICES.  Cost of services increased 25.5% to $9.0 million for the
nine months ended September 30, 1998 from $7.2 million for the comparable period
in 1997. This increase was mainly a result of an increase in home subscriber net
roaming costs as well as increased billing and call delivery expenses associated
with the growth in the subscriber base. The increase in net roaming costs is
attributed mostly to increased levels of intrasystem roaming for which rates to
customers are lower than other roaming traffic which has stimulated usage.
Partially offsetting this increase are lower costs to Sygnet for long distance
charges and the elimination of costs associated with a terminated switching
agreement. As a percentage of total revenue, cost of services was 11.7% for the
nine months ended September 30, 1998 compared to 11.4% for the same period in
1997.
 
                                       65
<PAGE>
    COST OF EQUIPMENT SALES.  Cost of equipment sales increased 14.5% to $7.8
million for the nine months ended September 30, 1998 from $6.8 million in the
comparable 1997 period. This increase was due mainly to an increased number of
telephones and accessories sold to existing subscribers, as well as equipment
subsidies and sales to new subscribers, offset by a reduction in the average
cost of telephones and accessories.
 
    GENERAL AND ADMINISTRATIVE COSTS.  General and administrative costs
increased 25.7% to $14.7 million for the nine months ended September 30, 1998
from $11.7 million for the comparable period in 1997. This increase was mainly a
result of the growth in the subscriber base which caused an increase in
compensation and increased customer retention costs due to competitive
pressures. As a percentage of total revenues, general and administrative expense
was 19.1% for the nine months ended September 30, 1998 compared to 18.6% for the
same period in 1997.
 
    SELLING AND MARKETING COSTS.  Selling and marketing costs increased 21.3% to
$9.1 million for the nine months ended September 30, 1998 from $7.5 million for
the comparable period in 1997. This increase is mainly due to an increase in new
subscribers added period to period which caused higher compensation and
commission expenses as well as an increase in advertising and promotional
expenses. Selling and marketing cost per gross new subscriber, including
equipment subsidies, decreased by 6.2% to $287 for the nine months ended
September 30, 1998 from $306 for the comparable period in 1997. This was
primarily a result of an improvement in the margin on telephone and accessory
subsidies and sales.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased 1.0%
to $21.3 million for the nine months ended September 30, 1998 from $21.1 million
for the comparable period in 1997 due primarily to the depreciation on higher
levels of fixed assets resulting from capital expenditures for system growth.
This increase more than offset the decrease in depreciation due to certain cell
site equipment obtained in the Horizon Acquisition which become fully
depreciated in April 1998. For the nine months ended September 30, 1998, Sygnet
incurred $11.5 million in capital expenditures, primarily for cell site and
system enhancements.
 
    INTEREST EXPENSE, NET.  Interest expense decreased 4.2% to $21.6 million for
the nine months ended September 30, 1998 from $22.6 million for the comparable
period in 1997. This decrease was primarily a result of a lower level of
borrowing due to the repayment of certain indebtedness with the proceeds from
the sale of common stock.
 
    YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
    REVENUE.  For 1997, Sygnet's total revenue increased 91.2% to $85.6 million
from $44.8 million for 1996. The growth in revenue was the result of the Horizon
Acquisition, which occurred on October 9, 1996, and continued growth of the
subscriber base.
 
    Subscriber revenue grew by 69.3% to $52.6 million for 1997 from $31.1
million for 1996 mainly as a result of the Horizon Acquisition and continued
subscriber growth. Subscriber revenue, on a pro forma basis giving effect to the
Horizon Acquisition, would have grown by 22.7% due to growth in the subscriber
base, offset by a decline in average revenue per subscriber. Sygnet's
subscribers grew by 34.1% to 142,934 at December 31, 1997 from 106,574 at
December 31, 1996 due mainly to internal growth. On a pro forma basis giving
effect to the Horizon Acquisition, average monthly subscriber revenue per
subscriber would have declined by 7.3% to $35.91 during 1997 from $38.75 in
1996. This was due to the changing mix of subscribers reflecting increasing
levels of subscribers purchasing less expensive rate plans that include limited
free minutes of use, increased promotional activity and competitive market
pressures.
 
    Roamer revenue increased 178.6% to $27.0 million during 1997 from $9.7
million for 1996. This increase was mainly a result of the Horizon Acquisition
as well as increased roaming traffic throughout all of Sygnet's systems. On a
pro forma basis giving effect to the Horizon Acquisition, roamer revenue would
have grown by 21.5% due to a greater volume of roaming traffic offset by a
reduction in roaming revenue
 
                                       66
<PAGE>
per minute. Roaming revenue per minute for 1997 would have decreased to $0.58
from $0.59 for 1996 on a pro forma basis giving effect to the Horizon
Acquisition mainly as a result of reductions in roaming rates with roaming
partners.
 
    Equipment sales increased 78.9% to $4.3 million for 1997 compared to $2.4
million for 1996. This increase was due mainly to the Horizon Acquisition, an
increased number of telephones and accessories distributed as new subscriber
acquisitions increased, as well as from additional sales of equipment to
existing customers. On a pro forma basis giving effect to the Horizon
Acquisition, equipment sales for 1997 would have increased 12.4% over 1996.
 
    COST OF SERVICES.  Cost of services increased 82.4% to $10.0 million during
1997 from $5.5 million for 1996 due mainly to the Horizon Acquisition. On a pro
forma basis giving effect to the Horizon Acquisition, cost of services for 1997
would have increased by 12.0% from 1996. This increase was mainly a result of an
increase in billing, call delivery and roaming costs associated with the growth
in the subscriber base, partially offset by lower rates for interconnection and
long distance charges. As a percentage of total revenues, on a pro forma basis
giving effect to the Horizon Acquisition, cost of services was 11.7% in 1997
compared to 12.7% in 1996.
 
    COST OF EQUIPMENT SALES.  Cost of equipment sales increased 66.2% to $9.7
million for 1997 from $5.8 million in 1996. This increase was due mainly to the
Horizon Acquisition and to an increased number of telephones and accessories
distributed as new subscriber acquisitions increased. Sales of equipment to
existing subscribers were also responsible for a portion of this increase. On a
pro forma basis giving effect to the Horizon Acquisition, cost of equipment
sales for 1997 would have increased 18.6% over 1996.
 
    GENERAL AND ADMINISTRATIVE COSTS.  General and administrative costs grew
72.3% to $17.0 million in 1997 from $9.9 million in 1996. This increase was due
primarily to the Horizon Acquisition and an increase in costs due to internal
growth. On a pro forma basis giving effect to the Horizon Acquisition, general
and administrative expenses for 1997 would have increased 19.8% over 1996. This
increase was mainly a result of an increase in compensation, customer retention,
occupancy and maintenance expenses associated with the growth in the subscriber
base as well as the additional cell sites added during 1997. As a percentage of
total revenues, on a pro forma basis giving effect to the Horizon Acquisition,
general and administrative expense would have been 19.8% in 1997 compared to
20.0% in 1996.
 
    SELLING AND MARKETING COSTS.  Selling and marketing costs grew 78.3% to
$10.8 million for 1997 from $6.1 million in 1996. This increase is due to the
Horizon Acquisition and a higher level of new subscribers added period to
period. On a pro forma basis giving effect to the Horizon Acquisition, selling
and marketing costs grew by 12.3% and selling and marketing cost per gross new
subscriber decreased to $291 in 1997 from $324 in 1996 reflecting a decrease in
cost of telephone and accessories in addition to improved operating
efficiencies.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased to
$28.7 million for 1997 from $10.0 million in 1996 due to depreciation on higher
levels of fixed assets resulting from the Horizon Acquisition and purchases of
equipment to enhance systems in existing markets, and amortization of the
license acquired in the Horizon Acquisition. The amortization of the acquired
cellular licenses and subscriber lists contributed $10.3 million to this
increased amortization. For 1997, Sygnet spent $25.6 million in capital
expenditures, primarily for new cell sites, cell site conversions, and system
growth.
 
    INTEREST EXPENSE, NET.  Interest expense increased to $29.9 million in 1997
from $11.2 million in 1996. This increase was primarily a result of increased
borrowings associated with the Horizon Acquisition.
 
    NET OPERATING LOSSES.  At December 1997, Sygnet had a net operating loss
carryforward of $28.7 million. No benefit of the loss carryforward has been
recorded in 1997. If, in the future, this loss carryforward is utilized, the
related benefits will be recorded.

    YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
    REVENUE.  For 1996, Sygnet's total revenue increased 82.3% to $44.8 million
from $24.6 million for 1995. The growth in revenue was the result of the Horizon
and Erie Acquisitions and continued growth of the subscriber base.
 
    Subscriber revenue grew 80.8% to $31.0 million for 1996 compared to $17.2
million for 1995 mainly as a result of the Horizon and Erie Acquisitions and
continued subscriber growth. Sygnet's subscribers increased to 106,574 at
December 31, 1996 from 44,665 at December 31, 1995 due mainly to the Horizon
Acquisition as well as internal growth. On a pro forma basis giving effect to
the Horizon Acquisition, the subscriber base increased by 36.8% to 106,574 at
December 31, 1996 from 77,891 at December 31, 1995. On a per subscriber basis
giving effect to the Horizon Acquisition, average monthly subscriber revenue
would have declined to $38.75 during 1996 from $41.66 in 1995 due in part to the
changing mix of subscribers reflecting increasing levels of subscribers
purchasing less expensive rate plans that include limited free minutes of use as
well as competitive market pressures.
 
    Roamer revenue increased 132.0% to $9.7 million during 1996 compared to $4.2
million in 1995. This increase was mainly a result of the Horizon and Erie
Acquisitions as well as increased roaming traffic throughout all of Sygnet's
systems. Roamer revenue per minute during 1996 decreased to $.55 from $.57 in
1995. This decrease was due mainly to reductions made to roaming rates received
from other cellular carriers in the first quarter of 1995 which were in effect
for the full year in 1996, mitigated by the effects of the Horizon Acquisition.
 
    Equipment sales increased 58.0% to $2.4 million in 1996 compared to $1.5
million in 1995. This increase was due mainly to the Horizon and Erie
Acquisitions and an increased number of telephones and accessories distributed
as new subscriber acquisitions increased, as well as from additional sales of
equipment to existing customers. Other revenue declined 4.4% to $1.6 million in
1996 from $1.7 million in 1995 as equipment rental revenue continued to decrease
due to the continued phase out of rental programs.
 
    COST OF SERVICES.  Cost of services increased 63.7% to $5.5 million in 1996
from $3.4 million in 1995 due mainly to the Horizon and Erie Acquisitions. Cost
of services decreased to 12.3% of total revenues in 1996 from 13.7% in 1995, as
a result of operating efficiencies gained from the Horizon and Erie
Acquisitions.
 
    COST OF EQUIPMENT SALES.  Cost of equipment sales increased 39.7% to $5.8
million in 1996 from $4.2 million in 1995. This increase was due mainly to the
Horizon and Erie Acquisitions and to an increased number of telephones and
accessories distributed as new subscriber acquisitions increased. The increased
cost of equipment sold resulting from the increase in gross activations was
mitigated by the declining cost to acquire new telephones.
 
    GENERAL AND ADMINISTRATIVE COSTS.  General and administrative costs
increased 77.1% to $9.9 million in 1996 from $5.6 million in 1995. This increase
is due primarily to the Horizon and Erie Acquisitions and the effects of a third
quarter 1995 one time adjustment to the personal property tax accrual resulting
from a substantial decrease in tax rates.
 
    SELLING AND MARKETING COSTS.  Selling and marketing costs increased 97.3% to
$6.1 million in 1996 from $3.1 million in 1995. This increase is due to the
Horizon and Erie Acquisitions and a higher level of new subscribers added period
to period. Selling and marketing cost per gross new subscriber, including
equipment subsidies, decreased 10.1% to $310.0 in 1996 from $345.0 for 1995 as a
result of a decrease in cost of telephones and accessories in addition to
improved efficiencies.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
187.9% to $10.0 million in 1996 from $3.5 million in 1995 due to depreciation on
higher levels of fixed assets resulting from the Horizon and Erie Acquisitions
and purchases for system growth, and amortization of the licenses acquired in
the Horizon and Erie Acquisitions. The amortization of the acquired cellular
licenses and subscriber
 
                                       68
<PAGE>
lists contributed $3.4 million to this increased amortization. For 1996, Sygnet
spent $10.0 million in capital expenditures, primarily for new cell sites, cell
site conversions, and system growth.
 
    INTEREST EXPENSE, NET.  Interest expense increased to $11.2 million in 1996
from $2.7 million in 1995. This increase was primarily a result of increased
borrowings associated with the Horizon and Erie Acquisitions.
 
    EXTRAORDINARY LOSS.  In October 1996, Sygnet incurred an extraordinary loss
of $1.4 million to write off unamortized financing costs associated with an
extinguished bank credit agreement.
 
IMPACT OF YEAR 2000 ISSUE
 
    DOBSON
 
    The Year 2000 issue is the result of computer programming being written
using two digits rather than four to define the applicable year. Any of the
Company's systems, as well as those of key suppliers and customers, that have
date sensitive logic may interpret a date using "00" as the year 1900 rather
than 2000. This may result in inaccurate processing or possible system failure
causing potential disruption of operations, including, among other things, a
temporary inability to process transactions, send invoices, supply services or
engage in similar normal business activities.
 
    In April 1998, the Company established a multi-disciplined team to perform a
Year 2000 impact analysis for the Company. 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, the Company has completed an inventory of its 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. All of the Company's automated systems and services
are or will be Year 2000 compliant by the end of the second quarter of 1999.
 
    The Company does not have large scale legacy applications used by many
telecommunications providers. From an information systems standpoint, the
Company has historically relied on outsourcing relationships for most of its
business and operational support applications. Those applications that have not
been outsourced to service providers have been deployed using packaged software
from outside vendors. Management has also focused on evaluating software systems
of pending acquisitions. As a result, the remediation 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 the Company's
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 the Company and should be in place
and tested by the second quarter of 1999. The Company estimates total costs of
approximately $.5 million to upgrade or replace those systems that are not Year
2000 compliant and will not be upgraded through existing maintenance or service
agreements. In addition, the Company's contingency plan for the Year 2000 is
encompassed by a disaster recovery plan for the business which will be in place
by the end of the second quarter of 1999.
 
    The Company will continue to analyze systems and services that utilize
date-embedded codes that may experience operational problems when the Year 2000
is reached. The Company 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
 
                                       69
<PAGE>
2000 compliance. To further mitigate risks, the Company will conduct its own
Year 2000 tests on mission critical systems as Year 2000 compliant versions are
released by vendors.
 
    SYGNET
 
    Sygnet has substantially completed an inventory of all its systems and
equipment in each market to determine the impact of the Year 2000 Issue. Based
on this inventory, Sygnet has contacted its significant vendors to determine how
their products and services might be affected by the Year 2000 Issue. Generally,
Sygnet is relying upon representations made by the vendors as to their state of
readiness for the Year 2000 Issue. Based on internal evaluations and on
information provided by these vendors certain systems have been upgraded and
tested for Year 2000 compliance. Sygnet estimates that it is 60% complete with
this phase of the project.
 
    Sygnet is placing special emphasis on areas that present a risk of
materially interrupting its revenue stream in the event of a Year 2000 problem.
Presently, it appears three main systems have the potential to materially
interrupt the revenue stream due to the Year 2000 Issue. They are the two
cellular switches, which could prevent calls from being made, and the billing
system, which could prevent Sygnet from billing and subsequently receiving
revenue from its customers. To address this risk, the Northern Telecom switch,
which serves Ohio and Pennsylvania, has recently undergone a software upgrade to
a Year 2000 compliant version. Sygnet has monitored testing of this software in
a Year 2000 situation with commonly known critical dates and has encountered no
problems. Accordingly, Sygnet has deemed this system to have a minimal risk of
failure regarding the Year 2000 Issue and will not develop contingency plans for
the Northern Telecom switch unless new information becomes available that
suggests a contingency plan is warranted. The Ericsson switch, which serves New
York, is expected to have its software upgraded to a Year 2000 compliant version
in the first quarter of 1999. It is expected that like Northern Telecom,
Ericsson will provide sufficient testing prior to installation. In connection
with the planned upgrade of the New York system, Sygnet plans to replace the
Ericsson switching equipment with Northern Telecom equipment that is believed to
be year 2000 compliant. In addition, the upgrade of the billing system software
to a Year 2000 compliant version is expected to be completed in the first
quarter of 1999. The vendor that provides this system has indicated that Year
2000 compliance testing will be completed by June of 1999. Sygnet has deemed
this system to have a moderate risk of not being able to handle the Year 2000
requirements and a contingency plan is being prepared that may include selecting
a new billing vendor in mid 1999.
 
    The cost of testing and upgrading these systems can not be determined at
this time. Management's current estimate is that the cost of becoming year 2000
compliant is not expected to exceed $250,000. This estimate may change
significantly downward or upward as the process continues or if problems arise
with either a switch or billing system. Additionally, this estimate may change
substantially if other systems or vendors are unable to become Year 2000
compliant causing a material interruption of the revenue stream.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    SYGNET
 
    Sygnet has historically relied on internally generated funds to fund debt
service and a substantial portion of its capital expenditures. Bank credit
facilities and equity issuances have been used for additional support of capital
expenditure programs and to fund acquisitions.
 
    Sygnet's net cash provided by operating activities was $13.5 million for the
nine months ended September 30, 1998 compared to $7.1 million for the comparable
period in 1997. The increase was primarily the result of the increase in
operating income, offset somewhat by a decrease in net working capital. Net cash
provided by operating activities was $9.4 million for 1997 compared to $14.8
million for 1996 and $2.4 million in 1995. This decrease from 1996 to 1997 was
primarily due to interest paid of $30.0 million in 1997 compared to $4.7 million
in 1996, which was offset significantly by the increase in revenue
 
                                       70
<PAGE>
due to growth in subscribers. The increase from 1995 to 1996 was primarily the
result of the increase in the number of subscribers and their related growth in
revenue.
 
    Sygnet's net cash used in investing activities was $11.1 million for the
nine months ended September 30, 1998 compared to $17.6 million for the
comparable period in 1997. In 1998, this activity reflects decreased levels of
purchases of property and equipment primarily for system buildout in addition to
proceeds of $300,000 associated with the sale of an undeveloped patent to an
officer/shareholder of Sygnet. In 1997, this activity reflects final payments
made in connection with the Horizon Acquisition and the completion of the
buildout of the system acquired in the Horizon Acquisition. Net cash used in
investing activities, which totaled $25.8 million, $264.2 million and $49.1
million for the years ended December 31, 1997, 1996 and 1995, respectively,
principally related to the system buildout in 1997, the Horizon Acquisition in
1996 and the Erie Acquisition in 1995 and capital expenditures required to
support the growth of the business.
 
    Sygnet's net cash used in financing activities was $2.9 million for the nine
months ended September 30, 1998 compared to $10.0 million provided by financing
activities for the comparable period in 1997 as the combination of reduced
capital expenditures and increased cash flow from operating activities reduced
the need for outside financing. In 1997, this activity included $43.6 million in
net proceeds from the sale of Sygnet's common stock which were used primarily to
redeem the remaining outstanding preferred stock and to reduce amounts
outstanding under the Sygnet Bank Facility and fund capital expenditures. Net
cash provided by financing activities was $15.0 million for 1997 compared to
$251.2 million for 1996 and $46.6 million in 1995. The 1996 amount includes
primarily funds received, net of financing cost, from the issuance of the Sygnet
Notes and preferred stock and borrowings under the Sygnet Bank Facility to fund
acquisitions. Dividends of $.3 million and $1.2 million were paid in 1996 and
1995, respectively.
 
    DOBSON
 
    The Company's cellular operations require substantial capital to acquire,
construct and expand wireless telephone systems and to fund operating
requirements. Dobson has financed its operations through bank debt and the sale
of debt and equity.
 
    At December 31, 1996, the Company had working capital of $10.6 million (a
ratio of current assets to current liabilities of 2.9:1) and a cash balance $1.0
million. At December 31, 1997, the Company had working capital of $15.9 million
(a ratio of current assets to current liabilities of 1.7:1) and a cash balance
of $2.8 million, which compares to working capital of $10.9 million (a ratio of
current assets to current liabilities of 1.2:1) and an unrestricted cash balance
of $5.0 million at September 30, 1998.
 
    The Company's net cash provided by operating activities totaled $20.7
million for the nine-month period ended September 30, 1997 compared to $10.4
million for the nine months ended September 30, 1998. The decrease of $10.3
million was primarily due to the Company's net loss for the 1998 period, of
which $17.2 million related to discontinued operations, offset by net changes in
current assets and liabilities, depreciation and amortization, and deferred
income taxes and investment tax credits.
 
    The Company's net cash provided by operating activities totaled $8.6 million
for 1995 compared to $11.6 million for 1996 and $12.3 million for 1997. The
increase of $3.0 million from 1995 to 1996 was primarily due to depreciation and
amortization and a loss on the disposition of assets offset by the Company's net
loss for the period. The increase of $.7 million from 1996 to 1997 was primarily
due to net changes in current assets and liabilities, depreciation and
amortization and deferred income taxes and investment tax credits, offset by the
Company's net loss for the period.
 
    Net cash used in investing activities totaled $189.1 million and $440.3
million for the nine months ended September 30, 1997 and 1998, respectively. In
1997, investing activities consisted primarily of acquisitions of systems in the
Eastern Region, as well as capital expenditures. The 1998 investing activities
 
                                       71
<PAGE>
principally related to acquisitions, escrow deposits and capital expenditures.
Of the 1998 investing activities, discontinued operations accounted for
approximately $17.8 million of capital expenditures and $131.5 million of
acquisition expenditures.
 
    Net cash used in investing activities, which totaled $11.1 million, $49.4
million and $221.1 million for the years ended December 31, 1995, 1996 and 1997,
respectively, principally related to deposits made in 1995 related to the
Maryland acquisitions and PCS license acquisitions, the Kansas/Missouri
acquisition in 1996 and the Maryland and Arizona acquisitions in 1997, as well
as capital expenditures in all periods. Acquisitions accounted for $30.0 million
and $190.7 million in 1996 and 1997, respectively, and capital expenditures were
$3.9 million, $17.4 million and $23.2 million in 1995, 1996 and 1997,
respectively.
 
    Net cash provided by financing activities was $168.5 million for the nine
months ended September 30, 1997 compared to $498.1 million for the nine months
ended September 30, 1998. Financing activities for the nine months ended
September 30, 1998 consisted primarily of $284.0 million of proceeds from
long-term debt and $175.0 million of proceeds from the issuance of Senior
Preferred Stock, offset by the repayment of $171.5 million of bank debt and
approximately $12.7 million of deferred financing costs in connection with the
issuance of Senior Preferred Stock and the March 1998 credit facilities
discussed below. In 1998, financing activities of the discontinued operations
provided proceeds of $350.0 million from the issuance of 12 1/4% Senior Notes.
Approximately $11.2 million of deferred financing costs were incurred in
connection with such Senior Notes offering.
 
    Net cash provided by financing activities was $1.8 million for 1995 compared
to $38.3 million for 1996 and $210.2 million for 1997, respectively. Financing
activities for the year ended December 31, 1997 consisted primarily of $343.5
million of proceeds from long-term debt, including the issuance of $160.0
million principal amount of Senior Notes and bank borrowings. Proceeds from
long-term debt exceeded repayment thereof by $2.7 million, $39.8 million and
$254.7 million in 1995, 1996, and 1997, respectively.
 
    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 $160.0
million of indebtedness under its revolving credit facilities. Subsequent to
September 30, 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 minority partners in the Company's partnerships that own certain of its
wireless operations receive distributions equal to their share of the profit
multiplied by estimated income tax rates. Under the Company's bank credit
agreements, the Company's 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 the Company is paid or
extinguished.
 
    The Company's capital expenditures (excluding cost of acquisitions and
discontinued operations) were $23.7 million for the nine months ended September
30, 1998 and the Company expects its capital expenditures (excluding cost of
acquisitions) to be approximately $30.2 million for all of 1998, exclusive of
acquisition costs, and $50.2 million for 1999. Of such capital expenditures for
1999, approximately $16.0 million is expected to relate to Sygnet and
approximately $4.0 million to Maryland 1. The Company has not budgeted any
amounts to be expended in 1998 or 1999 with respect to the systems which may be
acquired in other acquisitions or the Company's PCS system. The amount and
timing of capital expenditures may vary depending on the rate at which the
Company expands and develops its wireless systems and whether the Company
consummates additional acquisitions.
 
    On December 23, 1998, a subsidiary of the Company acquired all of the
outstanding capital stock of Sygnet for $337.5 million in cash. The Sygnet
Acquisition was financed through borrowings under the Credit Facilities, the net
proceeds of offering of the Preferred Stock, the Equity Investments and the
Tower Sale Leaseback. In addition, the Company expects to borrow $9.1 million
under the DOC Facility to close
 
                                       72
<PAGE>
the Maryland 1 Acquisition and $6.0 million under the New Credit Facilities to
close the Pennsylvania 2 Acquisition.
 
    The Company has agreed to purchase approximately $65 million of cell site
and switching equipment between June 1997 and November 2001. Of this commitment,
approximately $34.6 million remained at September 30, 1998. Under another
equipment supply agreement, the Company agreed to purchase approximately $81.0
million of cell site and switching equipment by January 13, 2002. Of this
commitment, $67 million remained at September 30, 1998.
 
    In April 1997, the Company was granted PCS licenses in nine markets in
Oklahoma, Kansas and Missouri. The Company 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. The Company is required to build out systems covering
25% of the population covered by each of the PCS licenses by 2002. The Company
currently anticipates 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 selected by the Company, the extent of the
Company's buildout, the costs at the time of buildout and the extent the Company
must bear the expense of relocating incumbent microwave licensees, as mandated
by FCC rules. The Company has not budgeted any amounts for capital expenditures
in 1998 or 1999 with respect to the buildout of a PCS system.
 
    In March 1998, the Company's subsidiary, Dobson Cellular Operations Company
("DCOC"), established a $200.0 million senior secured credit facility (the "DCOC
Facility"). Under the terms of the DCOC Facility, an additional $75.0 million
revolving credit facility may be established for acquisitions. This uncommitted
facility requires that the Company have borrowings outstanding of at least
two-thirds of the committed amount under the $200.0 million facility. DCOC's
obligations under the DCOC Facility are secured by all existing and future
assets of DCOC, and are guaranteed by DCOC' subsidiaries. In addition, the
Company's subsidiary, Dobson Operating Company ("DOC"), established a $250.0
million senior secured credit facility (the "DOC Facility") to replace a prior
bank facility. The DOC 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. The Company and DOC's subsidiaries, other than Logix
and the Arizona 5 Partnership, have guaranteed DOC's obligations under the DOC
Facility. The DCOC Facility and the DOC 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. The DOC Facility and DCOC Facility each amortize quarterly
beginning June 30, 2000 and terminate on June 30, 2006. At September 30, 1998,
the Company had credit available of $109.0 million under the DOC Facility and
$57.0 million under the DCOC Facility, subject to covenant limitations. See
"Description of Certain Indebtedness."
 
    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. The obligations under the New Credit
Facilities are secured by a pledge of the capital stock of Sygnet's operating
subsidiary as well as a lien on substantially all of the assets of Sygnet and
its operating subsidiary. The New Credit Facilities require Sygnet and the
Company to maintain certain financial ratios. The failure to maintain such
ratios would constitute an event of default, notwithstanding Sygnet's ability to
meet its debt service obligations. See "Description of Certain Indebtedness."
The ability of Sygnet to borrow under the New Credit Facilities will be limited
by the requirement that, on a quarterly basis beginning December 31, 2000, the
amount available under the New Credit Facilities will reduce until they
terminate.
 
    As part of the Sygnet Financing, Sygnet sold to Dobson Tower, a wholly owned
subsidiary of the Company, substantially all of the towers it owns for $25.0
million. Dobson Tower then leased these towers back to Sygnet under an operating
lease, with annual lease payments of approximately $1.6 million. Dobson Tower
obtained the funds for such purchase from borrowings under a new credit facility
of
 
                                       73
<PAGE>
$17.5 million and the sale of $7.5 million of preferred stock of Dobson Tower to
an affiliate of the Company.
 
    On September 30, 1998, after giving pro forma effect to the Sygnet
Acquisition and Sygnet Financing, the Company and its subsidiaries would have
had approximately $1,054.9 million of indebtedness outstanding.
 
    Although the Company cannot provide you any assurance, the Company believes
that, assuming successful implementation of the Company's strategy, including
the further development of its cellular systems and significant and sustained
growth in its cash flow, the net proceeds from the offering of the Old Shares,
together with the Equity Investments, borrowings under the New Credit
Facilities, the DOC Facility, the Tower Sale Leaseback, the DCOC Facility and
cash flow from operations, were sufficient to consummate the Sygnet Acquisition,
the Maryland 1 Acquisition and the Pennsylvania 2 Acquisition, to repay the
$25.0 million loan from Dobson to fund the earnest money deposit in connection
with the Sygnet Acquisition, to repay all outstanding indebtedness under the
Sygnet Bank Facility, to repurchase all of the Sygnet Notes in the Sygnet Note
Repurchase, to pay fees and expenses incurred in connection with the Sygnet
Acquisition and Sygnet Financing, and are expected to be sufficient to satisfy
the Company's currently expected capital expenditure, working capital and debt
service obligations. However, the Company will need to refinance the Credit
Facilities, the Senior Notes and the Dobson/Sygnet Notes at their maturities and
refinance its mandatory redemption obligations with respect to its preferred
stock, including the Preferred Stock and Senior Preferred Stock. The Company's
ability to do so will depend on, among other things, its financial condition at
the time, the restrictions in the instruments governing its indebtedness and
other factors, including market conditions beyond the control of the Company.
See "Risk Factors--Refinancing Risk." The actual amount and timing of the
Company's future capital requirements may differ materially from the Company's
estimates as a result of, among other things, the demand for the Company's
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. The Company 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. The
Company has not yet evaluated the impact of adopting SFAS 133 and has not
determined the timing or method of adoption of SFAS 133.
 
    In April 1998, the Accounting Standards Executive Committee issued Statement
of Position ("SOP") 98-5, "Reporting on the Costs of Start-Up Activities,"
effective for fiscal years beginning after December 15, 1998, with earlier
application encouraged. The Company adopted SOP 98-5 as of January 1, 1998. SOP
98-5 requires costs of start-up activities and organization costs to be expensed
as incurred. Logix recognized a pretax loss of approximately $1.2 million in the
first quarter of 1998 as a result of adopting this SOP. This loss has been
reflected in income (loss) from discontinued operations in the accompanying
consolidated statement of operations for the nine months ended September 30,
1998.

    The Company is a leading provider of rural and suburban cellular telephone
services. Since it began providing cellular service in 1990 in Oklahoma and the
Texas Panhandle, the Company has rapidly expanded its 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 September 30, 1998, the Company's cellular systems covered
2.8 million total Pops in Arizona, California, Kansas, Maryland, Missouri,
Oklahoma, Pennsylvania and Texas. On July 28, 1998, a subsidiary of the Company
entered into an agreement to acquire all of the outstanding capital stock of
Sygnet for $337.5 million in cash. Sygnet owns and operates cellular telephone
systems covering 2.4 million Pops in northeastern Ohio, western Pennsylvania and
western New York. For the nine months ended September 30, 1998, after giving
effect to the California 4 Acquisition and the Sygnet Acquisition as if each
acquisition had occurred on January 1, 1997, the Company would have had revenue
of $176.5 million, an operating loss of $13.7 million and Adjusted EBITDA of
$75.9 million.
 
    The Company believes that its 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. The Company focuses 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. Management believes 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. The Company has
entered into roaming agreements with operators of cellular systems in
neighboring MSAs and other MSAs that allow customers to roam at competitive
prices that, in certain instances, are comparable to the Company's home area
rates.
 
    The Company was organized to establish and maintain a strong and visible
local presence while achieving economies of scale and synergies through regional
and centralized functions. The Company's 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, the Company believes that its marketing and customer
service functions are more effective when tailored to the local market
population. The regional presence of Dobson's call centers enhances its
knowledge of local markets, which improves the Company's ability to provide
customer service, credit and collection and order activation. However, the
Company retains centralized control of marketing, customer service, pricing,
system design, engineering, purchasing, financial and administrative functions
to maximize operating leverage and continuity over its cellular systems.
 
    The Company has 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. The Company intends to apply these programs to the properties it
acquires. In addition to the Sygnet Acquisition, the Company recently closed
into escrow its 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. Recently, the Company 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
 
    The Company's business strategy is to focus on the development and
acquisition of rural and suburban cellular systems. The principal elements of
the Company's strategy include:
 
    INTEGRATE ACQUIRED OPERATIONS.  The Company intends to integrate the
operations of systems it acquires, including Sygnet, with the Company's existing
cellular operations to achieve economies of scale.
 
                                       75
<PAGE>
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. The Company expects to consolidate Sygnet's
three call service centers and one of the Company's call centers. Following
completion of the Maryland 1 Acquisition, the Company's subscribers and total
Pops will approximately double to 347,306 and 5.8 million, respectively. The
Company intends to use its increased leverage in negotiating prices and services
from third party service providers and equipment vendors.
 
    EXPAND STRATEGIC RELATIONSHIPS.  The Company intends to continue to maintain
and expand strategic relationships with operators of cellular systems in major
MSAs near the Company's systems. These relationships include roaming agreements
which allow the Company's subscribers to use the system in the neighboring MSA
at favorable rates. Under these agreements, similar benefits are available to
the MSA operator's subscribers roaming in the Company's areas. In addition, the
Company will deploy digital technology in its system area which is the same as
that selected by the Company's roaming partner in the neighboring MSA. The
Company also markets its cellular products and services under the predominant
brand name in the neighboring MSA. Such brand names include CELLULAR
ONE-Registered Trademark-, AIRTOUCH-SM- CELLULAR and AT&T Wireless
Services-Registered Trademark-. These strategic relationships and agreements
enable the Company to increase its 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-- Reliance on Use of
Third Party Service Marks."
 
    AGGRESSIVE LOCAL MARKETING AND PROMOTION OF CELLULAR SERVICES.  The
Company's marketing objective is to continue to distinguish itself as the local
market's leading cellular services provider, stressing its service quality,
local sales offices and commitment to the community. The Company's sales efforts
are conducted primarily through its retail outlets and its direct sales force
and, to a lesser extent, through independent agents.
 
    TARGETED SALES EFFORTS.  The Company seeks 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 the Company's cellular service.
 
    SUPERIOR CUSTOMER SERVICE.  The Company intends to maintain a high level of
customer satisfaction through a variety of techniques, including maintaining
24-hour customer service. The Company supports local customer service through
the Company's direct sales force and its retail stores, and through regional
customer service centers.
 
    CONTINUED SYSTEM DEVELOPMENT.  The Company believes that increasing capacity
and upgrading its systems will attract additional subscribers, enhance the use
of its systems by existing subscribers, increase roaming activity and further
enhance the overall efficiency of the network. The Company intends to continue
to upgrade its systems with digital technology to enable it to increase roaming
(by servicing the increasing number of digital cellular subscribers and PCS
subscribers with dual mode phones) and provide enhanced capabilities, including
caller ID, longer battery life and zone billing. From January 1, 1997 through
September 30, 1998, the Company installed digital technology in its Eastern and
Central Regions, with the exception of the Kansas/Missouri RSAs, and expects to
complete the installation of digital technology in its Western Region in 1999.
Sygnet's digital systems covered approximately 84% of the total Pops in its
market areas at September 30, 1998. The remaining Sygnet systems are expected to
be upgraded to digital during 1999. Substantially all of the Company's and
Sygnet's systems are or will be serviced by digital technology by the end of
1999.
 
                                       76
<PAGE>
    DISCIPLINED EXPANSION THROUGH ACQUISITIONS.  The Company continually
evaluates opportunities to acquire additional rural and suburban cellular
systems. In evaluating acquisitions, the Company targets 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.
 
The Company is presently evaluating, and is in discussions with, a number of
potential acquisition candidates. 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. The
Company has no agreements with respect to any acquisitions other the Maryland 1
Acquisition and the Pennsylvania 2 Acquisition.
 
DISCONTINUED OPERATIONS
 
    The Company, through its wholly owned subsidiary, Logix, provides 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
recently began offering switch-based integrated communications provider services
in Oklahoma City, Tulsa and Amarillo. In addition, since the consummation of the
American Telco Acquisition on June 15, 1998, it has offered these services in
Houston, Austin, Dallas, Fort Worth and San Antonio. For the year ended December
31, 1997 and the nine months ended September 30, 1998, Logix had revenues of
$20.2 million and $40.2 million, respectively, operating income (loss) of $3.2
million and $(10.6) million, respectively, and Adjusted EBITDA of $8.2 million
and $(2.9) million, respectively. At September 30, 1998, Logix had total assets
of $402.8 million, total debt of $377.9 million and shareholder's deficit of $.6
million.
 
    Logix has been designated an Unrestricted Subsidiary with respect to the
Preferred Stock and will not be subject to certain covenant restrictions which
apply to the rest of the Company's operations. The Company intends to distribute
the stock of Logix to certain of the Company's shareholders, subject to receipt
of a favorable tax ruling from the Internal Revenue Service. Logix is accounted
for as a discontinued operation in the Company's consolidated financial
statements.

CELLULAR OPERATIONS
 
    PRODUCTS AND SERVICES
 
    The Company provides 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, the Company offers ancillary services such as call
forwarding, call waiting, three-party conference calling, voice message storage
and retrieval and no-answer transfer. The nature of the services offered by the
Company varies depending upon the market area. The Company also sells cellular
equipment at discount prices and uses free phone promotions as a way to
encourage use of its mobile services. The Company offers 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 its competitors, the Company designs rate plans on a market-by-market basis.
The Company's 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, rate plans which
include a higher monthly access fee typically include a lower usage rate per
minute. An ongoing review of equipment and service plan pricing is maintained
and, as appropriate, revisions to pricing are made to meet the demands of the
local marketplace.
 
                                       84
<PAGE>
    CUSTOMER SERVICE
 
    Customer service is an essential element of the marketing and operating
philosophies of the Company. The Company is committed to attracting new
subscribers and retaining existing subscribers by providing consistently
high-quality customer service. In each of its cellular service areas, the
Company maintains installation and repair facilities and a local staff,
including a market manager, customer service representatives, technical and
sales representatives. Each cellular service area handles its own customer-
related functions such as customer activations, account adjustments and rate
plan changes. Local offices and installation and repair facilities enable the
Company to service customers better, schedule installations and make repairs.
Through the use of sophisticated, centralized monitoring equipment, the Company
will be able to centrally monitor the technical performance of its cellular
service areas.
 
    In addition, the Company's customers generally are able to report cellular
telephone service or account problems 24-hours a day to the Company's regional
customer service centers located in Oklahoma City, OK and Frederick, MD on a
toll-free access number (with no airtime charge). Upon consummation of the
Sygnet Acquisition, the Company intends to provide customer service for Sygnet's
markets through its Frederick, MD service center. The Company recently opened a
regional customer service center in California 4. Management believes its
emphasis on customer service affords it a competitive advantage over its large
competitors. The Company contacts its subscribers at frequent intervals in order
to evaluate and measure, on an ongoing basis, the quality and competitiveness of
its services.
 
    SALES, MARKETING AND DISTRIBUTION
 
    The Company focuses its marketing program on attracting subscribers who are
likely to generate high monthly revenue and low churn rates. The Company
undertakes extensive market research to identify and design marketing programs
to attract these subscribers and tailor distinctive rate plans and roaming rates
to emphasize the quality, value and advantage of the Company's cellular service.
The Company has established marketing alliances with neighboring cellular
systems to create larger home rate areas and to effectively expand the Company's
footprint in order to increase its roaming revenue and to attract new
subscribers. The Company markets its service offerings primarily through its
direct sales force and Company-owned retail stores. The Company also uses a
network of dealers and other agents, such as electronics stores, car dealerships
and department stores. In addition to these traditional channels, the Company's
marketing team continuously evaluates other, less traditional, methods of
distributing the Company's services and products, such as targeted telemarketing
and direct mail programs.
 
    The Company markets its cellular products and services under both national
brand names and a Company brand name. See "--Service Marks." The service mark
selected for use by the Company in each of its markets depends, to a large
extent, upon the service mark used in neighboring MSAs. The Company markets its
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, and Eastern Region markets, the Company markets its 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 the Company's advertising exposure
at a fraction of the cost of what could be achieved by the Company alone. The
Company uses the service mark AIRTOUCH-TM- CELLULAR in its southern California
and Arizona properties and expects to use a national brand name in central Texas
and the name CELLULAR ONE-Registered Trademark- in northern California. In its
Northern Region, the Company expects 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. In Ohio 2, the Company intends to use the service mark AIRTOUCH-TM-
CELLULAR. The service mark selected for use by the Company in each of its
clusters depends, to a large extent, upon the service mark used in neighboring
MSAs. See "--Service Marks."
 
    Management trains and compensates its sales force in a manner designed to
stress the importance of customer service, high penetration levels and minimum
acquisition costs per subscriber. The Company believes that its direct sales
force is better able to select and screen new subscribers and select pricing
plans
 
                                       85
<PAGE>
that realistically match subscriber means and needs than are independent agents.
In addition, the Company motivates its direct sales force to sell appropriate
rate plans to subscribers, thereby reducing churn, by linking payment of
commissions to subscriber retention. As a result, the Company's use of a direct
sales force keeps marketing costs low both directly, because commissions are
lower, and indirectly, because subscriber retention is higher than when
independent agents are used. The Company currently has 167 and Sygnet has over
60 direct sales agents.
 
    The Company believes that the after-sale telemarketing program conducted by
its sales force and customer service personnel helps to reduce its churn rate.
This program enhances customer loyalty and allows the sales staff to check
customer satisfaction as well as to offer additional calling features, such as
voicemail, call waiting and call forwarding.
 
    The Company operated 58 retail outlets and Sygnet operated 51 retail outlets
as of September 30, 1998. The Company's 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. The Company's stores
provide subscriber-friendly retail environments (extended hours, large
selection, an expert sales staff and convenient locations) which make the sales
process quick and easy for the subscriber.
 
    ROAMING
 
    The Company believes that regional roaming is an important service component
for many subscribers. Accordingly, where possible, the Company attempts to
arrange reciprocal roaming agreements that allow customers to roam at
competitive prices. The Company believes this increases usage on all cellular
systems, including the Company's. Roaming is a substantial source of revenue for
the Company. The Company focuses 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. The Company has
entered into roaming agreements with operators of cellular systems in adjoining
MSAs and others which provide for reciprocal roaming rates that allow customers
to roam at competitive prices which, in certain instances, are comparable to
home area rates. The following table lists the Company's principal roaming
partners in each of its cellular markets and in the markets to be acquired:

    The Company and Sygnet 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, the Company was 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 the Company 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. The Company has an agreement with AT&T
Wireless (PCS) under which the Company is a preferred roaming partner. See "Risk
Factors--PCS Risks," and "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 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.  The Company develops or builds out its cellular service
areas by adding channels to existing cell sites and by building new cell sites
with an emphasis on improving coverage for hand-held phones in
heavily-trafficked areas. Such development is designed to increase 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. The Company has historically met such
demand through a combination of augmenting channel capacity in existing cell
sites and building new cell sites. In January 1998, the Company 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
the Company under this agreement is estimated to be $81.0 million. The Company
is also 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.
 
    Cell site expansion is expected to enable the Company to continue to add and
retain subscribers, enhance subscriber use of the systems, increase roamer
traffic due to the larger geographic area covered by
 
                                       87
<PAGE>
the cellular network and further enhance the overall efficiency of the network.
The Company believes that the increased cellular coverage will have a positive
impact on market penetration and subscriber usage.
 
    The Company also continues to evaluate expansion through acquisitions of
other cellular properties that will further enhance its network. In evaluating
acquisition targets, the Company considers, among other things, demographic
factors, including population size and density, traffic patterns, cell site
coverage and required capital expenditures. See "--Strategy."
 
    DIGITAL TECHNOLOGY.  Digital signal transmission is accomplished through the
use of frequency management technologies, or "protocols." These protocols
"manage" the radio channel either by dividing it into distinct time slots (TDMA)
or by assigning specific coding instructions to each packet of digitized data
that comprises a signal (CDMA). While the FCC has mandated that licensed
cellular systems in the 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.
 
    Over the next decade, it is expected that many cellular systems will convert
from analog to digital technology. This conversion is due in part to capacity
constraints in many of the largest cellular markets, such as New York, Los
Angeles and Chicago. As carriers reach limited capacity levels, 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. The conversion from analog to digital
technology is expected to be an industry-wide process that will take a number of
years to complete. The Company has completed the conversion of many of its
systems to digital technology and expects to convert the remainder of its
systems (except for Kansas/ Missouri) by the end of 1999.
 
    The technology utilized by the Company will be governed, to a large extent,
by the technology used by the large, dominant carriers in MSAs near the
Company's systems. The timing of the conversions will be governed by the
conversion rate of larger, neighboring MSAs, market conditions and financial
considerations.

    SERVICE MARKS
 
    The Company owns the service mark Dobson Cellular-TM- which it uses in its
cellular telephone systems in western Oklahoma. While the Company has not
attempted to federally register the brand name "Dobson Cellular," the Company
believes that its prior use of this brand name in the limited areas where it is
used will enable the Company to effectively police against any infringing uses
of such brand name.

    CELLULAR ONE-Registered Trademark- is a registered service mark with the
U.S. Patent and Trademark Office. The service mark is owned by Cellular One
Group, a Delaware general partnership of Cellular One Marketing, Inc., a
subsidiary of SWBM, Cellular One Development, Inc., a subsidiary of AT&T
Wireless, and Vanguard. The Company uses the CELLULAR ONE-Registered Trademark-
service mark to identify and promote its cellular telephone service pursuant to
licensing agreements with Cellular One Group. Licensing and advertising fees are
determined based upon the population of the licensed areas. The licensing
agreements require the Company to provide high-quality cellular telephone
service to its customers and to maintain a certain minimum overall customer
satisfaction rating in surveys commissioned by the licensor. The licensing
agreements have original five-year terms that begin expiring in 2000 and may be
renewed at the Company's option, subject to the satisfaction of certain
operating standards, for two additional five-year terms.
 
    AIRTOUCH-TM- CELLULAR is a registered service mark licensed by AirTouch. In
connection with the Arizona 5 Acquisition, the Company entered into a licensing
agreement which permits the Company to use the AIRTOUCH-TM- CELLULAR service
mark to identify and promote its cellular telephone service in Arizona 5. The
Company's right to use the service mark in the territory is non-exclusive and
non-transferrable. The licensing agreement for the AIRTOUCH-TM- CELLULAR mark
requires the Company to provide high-quality cellular telephone services to its
customers and to otherwise maintain reasonable standards set by AirTouch. The
licensing agreement is for an initial term of 20 years with automatic extensions
for additional five-year periods.
 
    The Company intends to market its services using CELLULAR
ONE-Registered Trademark- in the Sygnet properties, except in the Youngstown
market where it will continue to market its services under the name "Wilcom
Cellular." The Company intends to market its services using the name
AIRTOUCH-TM- CELLULAR in Ohio 2 and CELLULAR ONE-Registered Trademark- in Texas
10. However, the Company has not yet entered into any license agreements with
respect to Ohio 2 and Texas 10, and the Company cannot assure you that it will
be able to do so.

    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, the Company
expects 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 the Company competes will be 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
the Company. 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 the Company's
competitors are operating, or planning to operate, through joint ventures and
affiliation arrangements, wireless telecommunications systems that encompass
most of the United States.
 
    The Company competes primarily against one other facilities-based cellular
carrier in each of its RSA and MSA markets. Competition for customers between
cellular licensees is based principally upon price, the services and
enhancements offered, the quality of the cellular system, customer service,
system coverage and capacity. Such competition may increase to the extent that
licenses are transferred from smaller, stand-alone operators to larger, better
capitalized and more experienced cellular operators that may be able to offer
consumers certain network advantages.
 
    Cellular carriers 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, cellular operators may also
compete more directly with traditional landline telephone service providers.
Continuing technological advances in telecommunications make it impossible to
predict the extent of future competition. However, due to the depth and breadth
of these competitive services offered by operators
 
                                       91
<PAGE>
using these other technologies, such competition could be significant and is
expected to become more intense.
 
    The FCC requires that all cellular system operators provide service to
resellers on a nondiscriminatory basis. A reseller provides cellular service to
customers but does not hold an FCC license or own cellular facilities. Instead,
the reseller buys blocks of cellular telephone numbers from a licensed carrier
and resells service through its own distribution network to the public.
Therefore, a reseller may be both a customer of a cellular licensee's services
and a competitor of that licensee. Several well-known telecommunications
companies resell cellular service as a complement to their long distance, local
telephone, paging, cable television or internet offerings.
 
    The most likely 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
the Company have access to substantial capital resources. In addition, many of
these companies or their predecessors and affiliates already operate large
cellular telephone systems and thus bring significant wireless experience.
 
    ESMR is a wireless communications service supplied by converting analog SMR
services into an integrated, digital transmission system. The ESMR system
incorporates characteristics of cellular technology, including multiple low
power transmitters and interconnection with the landline telephone network. ESMR
service providers such as Nextel 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 the Company may experience increased
competition from low earth-orbit satellite-based systems in the future, to date,
such systems have not affected the Company's operations.
 
    The commercial development and deployment of most of these new technologies
remain in an early phase. The Company expects this activity to be focused
initially in relatively large markets in view of the substantial costs involved
in building and launching systems using these technologies. The Company believes
that it can effectively face this competition from its position as an incumbent
in the cellular industry with a high quality network, an extensive footprint
that is not capacity constrained, strong distribution channels, superior
customer service capabilities and an experienced management team. Since the
Company operates in medium to small markets, the new entrants may be unable to
offer wireless service at competitive rates in many of the Company's markets in
the near term. The extensive capital expenditures required to deploy
infrastructure are more readily justifiable from an economic standpoint in
larger, more densely populated urban areas, than in the rural areas in which the
Company operates.

REGULATION
 
    OVERVIEW.  The wireless telecommunications industry is subject to extensive
governmental regulation on the federal level and to varying degrees on the state
level. Many aspects of such regulation have recently been impacted by the
enactment of the Telecommunications Act and are currently the subject of
administrative rulemakings and judicial proceedings that are significant to the
Company. The following is a summary of the federal laws and regulations that
materially affect the wireless telecommunications industry and a description of
certain state laws. This section does not purport to be a summary of all present
and proposed federal, state and local regulations and legislation relating to
the 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 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).
 
    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 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 period has expired in all its markets. The
Company's buildout has been substantially completed in all of its markets.
 
    Cellular service providers also must satisfy a variety of FCC requirements
relating to technical and reporting matters. One such requirement is the
coordination of proposed frequency usage with adjacent cellular users,
permittees and licensees in order to avoid interference between adjacent
systems. In addition, the height and power of base station transmitting
facilities and the type of signals they emit must fall within specified
parameters. The Company is obligated to pay 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 the Company of a controlling
interest in any license or construction permit, or any
 
                                       93
<PAGE>
rights thereunder, including the Sygnet Acquisition. All applications for FCC
approval filed in connection with the Sygnet Acquisition have been granted by
the FCC and became final on December 8, 1998. Although there can be no assurance
that any future requests for approval of applications filed will be approved or
acted upon in a timely manner by the FCC, the Company has no reason to believe
such requests or applications would not be approved or granted in due course.
 
    The FCC also regulates a number of other aspects of the cellular business.
For example, the FCC regulates cellular resale practices and recently extended
the resale requirement to broadband PCS and ESMR licensees. Cellular, PCS and
ESMR providers may not restrict any customer's resale of their services or
unreasonably discriminate against resellers of their services. All resale
obligations for cellular, broadband PCS and ESMR operators will terminate on
November 24, 2002. The FCC has also adopted requirements for cellular and other
providers of two-way voice services to implement basic and enhanced 911
services. These services provide emergency service providers with the ability to
better identify and locate callers using wireless services, including callers
using special devices for the hearing impaired. The Company's obligations to
implement these services is scheduled to occur in several stages ending in
October 2001. Cellular and PCS carriers are also required to provide law
enforcement agencies with capacity to support lawful wiretaps by March 12, 2001
and technical assistance for wiretaps by June 30, 2000. These wireless 911 and
law enforcement requirements may create additional capital obligations for the
Company to make necessary system changes.
 
    In addition, the FCC regulates the ancillary service offerings that cellular
and PCS licensees can provide and recently revised its rules to permit cellular,
broadband PCS, paging and ESMR licensees to offer fixed services on a co-primary
basis along with mobile services. This rule change may facilitate the provision
of wireless local loop service, which involves the use of wireless links to
provide local telephone service by cellular licensees, as well as broadband PCS
and ESMR licensees. In this regard, the FCC also recently adopted telephone
number portability rules for local exchange carriers, as well as cellular,
broadband PCS and ESMR licensees, that could facilitate the development of local
exchange competition, including wireless local loop service. The new number
portability rules generally require cellular, broadband PCS and ESMR licensees
to have the capability to deliver calls from their systems to ported numbers by
December 31, 1998 and offer number portability and roaming to ported numbers by
March 31, 2000. These requirements may result in added capital expenditures for
the Company to make necessary system changes, although the Company currently has
no plans for any such expenditures.
 
    Initial cellular and PCS licenses are generally granted for terms of ten
years, beginning on the date of the grant of the initial operating authority,
and are renewable upon application to the FCC. The initial term for three of the
Company's existing licenses expired in October 1998. Each license was renewed
for a new ten year term expiring in 2008. The balance of the Company's existing
licenses begin to expire in October 2000. Three of Sygnet's licenses have
already been renewed for a new ten year term, and the initial terms on the
balance of its licenses will expire over the next three years. Licenses may be
revoked and license renewal applications denied for cause after appropriate
notice and hearing. Near the conclusion of the license term, licensees must file
applications for renewal of licenses to obtain authority to operate for up to an
additional 10-year term. The FCC will award a renewal expectancy to a cellular
licensee that meets certain standards of past performance. If the existing
licensee receives a renewal expectancy, it is very likely that the existing
licensee's cellular license will be renewed without becoming subject to
competing applications. To receive a renewal expectancy, a licensee must show
that it has provided "substantial" service during its past license term, and has
substantially complied with applicable FCC rules and policies and the
Communications Act. "Substantial" service is defined as service which is sound,
favorable and substantially above a level of mediocre service that might only
minimally warrant renewal. If the existing licensee does not receive a renewal
expectancy, competing applications for the license will be accepted by the FCC.
The parties will be subject to a comparative hearing and the license may be
awarded to another entity.
 
                                       94
<PAGE>
    In order to increase competition in wireless communications, promote
improved quality and service and make available the widest possible range of
wireless services, federal legislation was enacted authorizing the FCC to
license radio frequency spectrum for all CMRS licensees, including PCS, by
competitive bidding. A PCS system operates under a protected geographic service
area license granted by the FCC for either an MTA or BTA on one of six frequency
blocks allocated for broadband PCS service. The FCC has divided the United
States and its 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.
 
    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. 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 licensees must provide service to at least 25% of the
service area 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. The Company was qualified to hold C and F licenses at the time such
licenses were awarded, and anticipates remaining so qualified throughout the
term of the PCS licenses awarded to it.
 
    For a period of up to five years after the grant of a PCS license (subject
to extension), a PCS licensee will be prohibited 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 its PCS
systems efficiently and with adequate population coverage, the Company may
therefore need to relocate many of these incumbent licensees, at the Company's
expense, to other frequencies or to reimburse other previously-licensed PCS
licensees for expenses they have incurred in relocating incumbent licensees that
the Company might have otherwise 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 (i) a transition plan to relocate such
microwave operators to other spectrum blocks and (ii) 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
 
                                       95
<PAGE>
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. The Company has not yet determined the
extent, if any, of expenses it may need to incur for the relocation of microwave
incumbents in order to provide PCS services using the PCS licenses it has been
awarded.
 
    Applications for FCC authority may be denied and in extreme cases licenses
may be revoked if the FCC finds that an entity lacks the requisite "character"
qualifications to be a licensee. In making the determination, the FCC considers
whether an applicant or licensee has been the subject of adverse findings in a
judicial or administrative proceeding involving felonies, the possession or sale
of unlawful drugs, fraud, antitrust violations or unfair competition, employment
discrimination, misrepresentations to the FCC or other government agencies, or
serious violations of the Communications Act or FCC regulations. If greater than
25 percent of the Company's equity is owned of record or voted by aliens or
their representatives, a foreign government or its representative, or any
corporation organized under the laws of a foreign country and the FCC determines
that the public interest would be so served, it may revoke the Company's
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 the Company's ability to
attract additional equity financing.
 
    Interconnection charges paid to local exchange carriers are a major
component of the cost structure of the Company and Sygnet. Changes in the
interconnection charge rate structure imposed by the FCC or mandated by the
Telecommunications Act may have a material impact on the Company.
 
    The Telecommunications Act, which makes significant changes to the
Communications Act and terminated the antitrust consent decree applicable to the
Regional Bell Operating Companies ("RBOCs"), affects the telecommunications
industry. This legislation, among other things, affects competition for local
telecommunications services, interconnection arrangements for carriers,
universal service funding and the provision of interexchange services.
 
    The Telecommunications Act requires state public utilities commissions
and/or the FCC to implement policies that mandate reciprocal compensation
between local exchange carriers, a category that will, for these purposes,
include cellular carriers, for interconnection services at rates more closely
related to cost. On August 1, 1996, the FCC adopted rules implementing the
interconnection policies imposed by the Telecommunications Act. Various aspects
of the order not directly related to interconnection between wireless carriers
and local exchange carriers are currently being reviewed by the U.S. Supreme
Court and the FCC's orders are currently subject to a federal appellate court
stay. If the FCC's rules are upheld on appeal, such action could result in
further reductions of the Company's interconnection expenses.
 
    The Telecommunications Act requires, 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 the Company's cellular operations. The
Telecommunications Act also eases the restrictions on the provision of
interexchange telephone services by wireless carriers affiliated with RBOCs.
RBOC-affiliated wireless carriers have interpreted the legislation to permit
immediate provision of in region long distance call delivery for their cellular
customers.
 
                                       96
<PAGE>
    The Telecommunications Act specifically exempts all cellular carriers from
the obligation to provide equal access to interstate long distance carriers.
However, the Telecommunications Act gives the FCC the authority to impose rules
to require unblocked access through carrier identification codes or 800/888
numbers, so that cellular subscribers are not denied access to the long distance
carrier of their choosing, if the FCC determines that the public interest so
requires. The Company currently provides "dial around" equal access to all of
its customers.
 
    The Telecommunications Act also imposes restrictions on a telecommunications
carrier's use of customer proprietary network information. FCC rules
implementing these restrictions could impose new costly obligations on the
Company and impose burdens on its current marketing activities.
 
    The overall impact of the Telecommunications Act on the business of the
Company is unclear and will likely remain so for the foreseeable future. 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 the Company to additional costs and increased competition.
 
    STATE, LOCAL AND OTHER REGULATION.  The Communications Act preempts state or
local regulation of the entry of, or the rates charged by, any commercial mobile
service or any private mobile service provider, which includes cellular
telephone service providers. The FCC has denied the petitions of eight states to
continue their rate regulation authority, including authority over cellular
operators. As a practical matter, the Company is free to establish rates and
offer new products and service with a minimum of regulatory requirements. The
states in which the Company operates, and in which it will operate upon
completion of the proposed wireless acquisitions, maintain nominal oversight
jurisdiction, primarily focusing upon prior approval of acquisitions and
transfers and resolution of customer complaints.
 
    The location and construction of cellular transmitter towers and antennas
are subject to FCC and Federal Aviation Administration ("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 a system can be put
into commercial operation, the grantee of a construction permit must obtain all
necessary zoning and building permit approvals for the cell 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.
 
    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, under the
Telecommunications Act, localities are now precluded 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, localities are prohibited 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.
 
    The Company cannot assure you that any state or local regulatory
requirements currently applicable to the Company's systems will not be changed
in the future or that regulatory requirements will not be adopted in those
states and localities which currently have none.
 
                                       97
<PAGE>
    FUTURE REGULATION.  From time to time, legislation that could affect the
Company, either beneficially or adversely, is proposed by federal or state
legislators. The Company 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 the
business of the Company. Changes such as the allocation by the FCC of radio
spectrum for services that compete with the Company's business could adversely
affect the Company's operating results.
 
EMPLOYEES AND AGENTS
 
    As of September 30, 1998, the Company had approximately 470 employees. In
addition, as of such date, the Company had agreements with 167 independent sales
agents, including car dealerships, electronics stores, paging service companies
and independent contractors. None of the Company's employees are represented by
a labor organization, and the Company considers its employee relations to be
good.
 
PROPERTIES
 
    The Company maintains its corporate headquarters in Oklahoma City, Oklahoma.
The Company leases this space, which is approximately 24,600 square feet, at a
monthly rental of approximately $19,000. See "Management--Certain Transactions."
As of September 30, 1998, the Company's cellular operations leased 30 and owned
three sales and administrative offices, at aggregate annual rentals of
approximately $.7 million. The Company anticipates that it will review these
leases from time to time and may, in the future, lease or acquire new facilities
as needed. The Company expects to lease or purchase additional sales and
administrative office spaces in connection with the Pending Acquisitions. The
Company does not anticipate that it will encounter any material difficulties in
meeting its future needs for any leased space. The Company also owned and leased
210 cell sites as of September 30, 1998.
 
    Sygnet owns office buildings in Youngstown and Warren, Ohio and land for a
proposed office site in Boardman, Ohio. As of September 30, 1998, Sygnet's
cellular operations leased 55 and owned two retail sales and administrative
offices. Sygnet anticipates that it will review these leases from time to time
and may, in the future, lease or acquire new facilities as needed. Sygnet does
not anticipate that it will encounter any material difficulties in meeting its
future needs for any leased space. Sygnet owned four cell sites and 124 towers
and leased 177 cell sites and ten towers as of September 30, 1998. Substantially
all of Sygnet's owned towers will be included in the Tower Sale Leaseback.
 
LEGAL PROCEEDINGS
 
    Neither the Company nor Sygnet is currently involved in any pending legal
proceedings that individually or in the aggregate are material to the Company.
Each of the Company and Sygnet is a party to routine filings and customary
regulatory proceedings with the FCC and the state public utility commissions
relating to its operations.

EMPLOYMENT AGREEMENTS
 
    In connection with the employment of Bruce R. Knooihuizen in 1996 and G.
Edward Evans in 1997, the Company agreed to provide them compensation in the
form of salary, bonus, stock options and other benefits. The terms of Mr.
Knooihuizen's 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 Class B Common Stock at $100 per share vesting at the
rate of 20% per year. The terms of Mr. Evans' 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 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. The Company 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 Class B Common Stock held by
these officers become fully vested upon a change of control of the Company.
 
    Effective September 1, 1998, the Company entered into a consulting agreement
with Russell L. Dobson. Under the terms of the agreeement, Mr. Dobson has been
retained by Dobson Communications from September 1, 1998 through August 31,
2008. In exchange for Mr. Dobson's services, the Company will provide monthly
compensation of $15,000 and insurance benefits commensurate with the Company's
employee plan. Mr. Dobson's responsibilities will include representing the
Company at various functions, assisting with regulatory matters and assisting
executive officers of the Company in strategic planning and forecasting. In
addition, Mr. Dobson has agreed not to compete with the Company. During 1998,
Mr. Dobson was paid approximately $195,000 by the Company under the consulting
agreement.
 
    Effective December 23, 1998 Albert H. Pharis, Jr. became a consultant to the
Company, to assist the Company 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 the Company's Class B Common
Stock at an exercise price of $665 per
 
                                      103
<PAGE>
share. Mr. Pharis's option vests ratably over a five-year period and fully vests
upon a change of control of the Company.
 
DIRECTOR COMPENSATION
 
    The Company reimburses directors for out-of-pocket expenses incurred in
attending board meetings. Justin L. Jaschke, in connection with his election as
a director by the Fleet Investors in October 1996, was granted an option to
acquire 833 shares of 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 of the Company. Directors who are officers or
consultants to the Company receive no additional compensation for services
rendered as directors.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The Compensation Committee of the Board of Directors of the Company
determines the compensation of the Company's 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. For a description of certain transactions between Mr. Dobson and the
Company, see "--Certain Transactions."
 
STOCK OPTION PLAN
 
    The Company's 1996 Stock Option Plan, as amended (the "Plan") was adopted to
encourage key employees of the Company (including Dobson and any present or
future parent or subsidiary of Dobson) by providing opportunities to participate
in the ownership of Dobson and its future growth through the grant of incentive
stock options and nonqualified stock options. The Plan also permits the grant of
options to directors. The Plan is presently administered by the 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 December 31, 1998
options to purchase an aggregate of 29,767 shares of Class B Common Stock and
2,414 shares of Class C Common Stock had been granted under the Plan.
 
    The maximum number of shares for which options may be granted 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 in control events.
Shares subject to previously expired or terminated options become available
again for grants of options. The shares to be issued under the Plan will be
newly issued shares.
 
    The number of shares and other terms of each grant are determined by the
Committee. The price payable upon the exercise of an incentive stock option may
not be less than 100% of the fair market value of the Class B Common Stock of
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 stock of the Company (a "10%
Shareholder"), 110% of the fair market value on the date of grant. Incentive
stock options may be granted to an employee only to the extent that the
aggregate exercise price of all such options under all Company 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 granted 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 the Company,
accompanied by an instrument of accession providing that the optionee agrees to
be bound by the terms applicable to shareholders under the Shareholders'
Agreement and full payment of the purchase price in cash or, at the discretion
of the
 
                                      104
<PAGE>
Committee, (i) Common Stock having a fair market value equal to the exercise
price, (ii) 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), (iii) an
assignment of proceeds from the sale of a portion of the stock subject to the
option being exercised, or (iv) 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 the dissolution or liquidation of Dobson.
 
    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
 
    The Company has adopted a policy requiring that any material transaction
between the Company and persons or entities affiliated with officers, directors
or principal stockholders of the Company be on terms no less favorable to the
Company than reasonably could have been obtained in an 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.
 
    In the Reorganization in February 1997, the shareholders of DOC exchanged
their DOC stock for Dobson stock, and Dobson assumed outstanding DOC stock
options, substituting shares of Dobson's Class B Common Stock for the DOC stock
subject to options. Also, in February 1997, Dobson issued 100,000 shares of its
Class C Preferred Stock to the Fleet Investors (each holding the same number of
shares as it holds of Class B Preferred Stock). See "Description of the
Preferred Stock."
 
    Transactions with the Company described below refer to DOC if they occurred
prior to February 1997.
 
    In March 1996, the Fleet Investors purchased 100,000 shares of Class B
Preferred Stock from the Company for $10.0 million. In connection with this
transaction, the Company and its shareholders entered into a Shareholders'
Agreement providing for, among other matters, registration rights, restrictions
on the transfer of Company 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 the Company a stock option. In
connection with the Reorganization, Dobson and its shareholders entered into a
new Shareholders' Agreement having substantially the same terms and conditions.
In January 1998, the Company issued the Fleet Investors 100,000 shares of Class
C Preferred Stock. In connection with the Sygnet Financing, 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 replaced with a new shareholders' agreement and the
option granted to the Company by the Fleet Investors will terminated.
 
    The Everett R. Dobson Irrevocable Family Trust, Steven T. Dobson Irrevocable
Family Trust and Robbin L. Dobson Irrevocable Family Trust (collectively, the
"Dobson Trusts") were co-borrowers with the Company and certain of its
subsidiaries under a prior bank facility, which was first entered into in 1994.
The Dobson Trusts are the limited partners of the Dobson Partnership, which
holds more than 99% of Dobson's Class A Common Stock and, prior to the
Reorganization, held more than 99% of DOC's Class A Common Stock. See "Principal
Shareholders." The Company and its borrower subsidiaries guaranteed, and the
Company pledged the equity securities of certain of its 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 the
loan obligations of the Company and its subsidiaries under the prior bank
facility. All borrowings were secured by the Class A Common Stock. In accordance
with the terms of the Fleet Investors Purchase Agreement and the prior bank
facility, the Company 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 the Company.
In connection with the Reorganization, the Company used $7.5 million of
 
                                      105
<PAGE>
bank borrowings to pay a dividend to holders of its 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 the Company 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, the Company consolidated $263,000 of
ATTI's outstanding indebtedness to the Company 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 the Company in the aggregate principal amount of $307,000,
representing funds advanced by the Company 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 the Arizona 5 Acquisition. The Company 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, the Company 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, Company 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 the Company 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 ATTI and its subsidiaries for
management services rendered prior to September 30, 1997 were paid in October
1997 in connection with the closing of the Arizona 5 Acquisition. In connection
with the Arizona 5 Acquisition, ATTI became a wholly owned subsidiary of the
Company, and a new company, NATELCO, LLC (an affiliate of Everett R. Dobson and
Russell L. Dobson), was created. For the year ended December 31, 1997 and the
nine months ended September 30, 1998 the amounts billed for management fees and
expenses to NATELCO, LLC were $21,000 and $47,700, respectively. The amounts
owed by NATELCO, LLC to the Company for management fees at December 31, 1997 and
September 30, 1998 were $8,900 and $8,200, respectively.
 
    ATTI beneficially owned a 20.55% partnership interest in the Arizona 5
Partnership. In connection with the Arizona 5 Acquisition, the Company 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 negotiations between the Company and the other partner of the
Arizona 5 Partnership.
 
    In March 1996, the Company made a $1.4 million unsecured loan to Everett R.
Dobson. The loan was repaid on October 1, 1997 in connection with the Arizona 5
Acquisition. Interest on the amount borrowed was payable quarterly at the same
annual rate as that payable under the Company's 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 favor of the
Company in the amount of approximately $354,000, which refinanced loans made to
him by the Company during 1996, together with accrued interest. The loan was
repaid on October 1, 1997 in connection with the Arizona 5 Acquisition. The loan
bore interest at 8% per annum. In December 1996, the Company 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, the Company made an additional loan to Russell L. Dobson in
the principal amount of $423,000, of which $304,000 consolidated amounts owed to
the Company 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 the Arizona 5 Acquisition. The
interest rate charged on the loan to Everett R. Dobson represented the Company's
costs of borrowed funds. The interest rate on the loans to Russell L. Dobson
approximated
 
                                      106
<PAGE>
the prevailing market rates at the time the loans were first made. In 1993,
Steven T. Dobson was indebted to the Company in the principal amount of $7,500,
which loan was paid in full in March 1995.
 
    Prior to November 1, 1998, the Company leased its 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, the Company 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, the Company loaned WillRuss $60,000, which was paid in full in
September 1995, together with interest at an annual rate of 10%.
 
    The Company 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 1995, the Company 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,
the Company 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 the Company and purchased the Company's 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, the Company 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 the Company's cost. In September 1997,
the Company 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 the
Company's cost plus accrued interest. Everett R. Dobson, an executive officer,
director and principal shareholder of the Company, was a director of Zenex from
August 1995 to September 1997.
 
    In November 1997, Everett R. Dobson purchased an interest in the Company's
loan to Gila River Telecommunications Subsidiary, Inc., a wholly owned
subsidiary of the Gila River Indian Community. The Company repurchased this
interest in June 1998.
 
    In January 1998, a subsidiary of the Company 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 Financing, the Company purchased for $1.9
million all of its outstanding shares (100,000 shares) of Class C Preferred
Stock held by the Fleet Investors and also purchased 43,348 shares of its Class
A Common Stock from Fleet Investors for $31.1 million. Thadeus J. Mocarski, a
principal of the Fleet Investors, was a director of the Company and resigned as
a director upon consummation of the Sygnet Acquisition. As part of the Sygnet
Financing, the Dobson Partnership acquired 37,630 shares of Class G Preferred
Stock from the Company 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 entered into by the
Company in connection with the Sygnet Financing.
 
    In the Tower Sale Leaseback, Dobson Tower Company purchased cellular towers
from Sygnet for $25.0 million and lease the towers back to Sygnet. Everett R.

                       DESCRIPTION OF THE PREFERRED STOCK
 
    The summary contained herein of certain provisions of the Preferred Stock
does not purport to be complete and is qualified in its entirety by reference to
the provisions of the Certificate of Designation, the form of which will be made
available from the Company upon request. The definitions of certain terms used
in the Certificate of Designation and in the following summary are set forth
under "--Certain Definitions."
 
GENERAL
 
    The Certificate of Incorporation of the Company 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. The Company has
authorized 2,500,000 shares of preferred stock, par value $1.00, including
184,000 shares of Preferred Stock, with a liquidation preference of $1,000 per
share. Such shares include the 64,646 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 the Company elects to pay dividends in
additional Preferred Stock. The Company filed a Certificate of Designation with
respect thereto with the Secretary of State of Oklahoma as required by Oklahoma
law. The Preferred Stock will be exchangeable, at the option of the Company,
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 the Company,
ranks (i) senior to all classes of Common Stock of the Company, Class A
Preferred Stock, the Class D Preferred Stock, the Class E Preferred Stock, the
Class F Preferred Stock, the Class G Preferred Stock, the Class H Preferred
Stock and to each other class of capital stock or series of preferred stock
established after the date of this Memorandum 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 the
liquidation, winding-up and dissolution of the Company (collectively referred
to, together with all classes of Common Stock of the Company, as the "Junior
Securities"); (ii) on a parity with the Senior Preferred Stock and, subject to
certain conditions, with any class of capital stock or series of preferred stock
issued by the Company established after the date of this Memorandum by the Board
of Directors, 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 the liquidation, winding-up and dissolution of the Company
(collectively referred to as "Parity Securities"); and (iii) subject to certain
conditions, junior to each class of capital stock or series of preferred stock
issued by the Company established after the date of this Memorandum by the Board
of Directors, 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 liquidation, winding-up and dissolution of the Company
(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 the Company 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 Stock, the Company may issue shares of Senior
Securities in exchange for, or the proceeds of which are used to redeem or
repurchase, (1) all (but not less than all) shares of Preferred Stock then
outstanding or (2) indebtedness of the Company.
 
                                      109
<PAGE>
DIVIDENDS
 
    Holders of Preferred Stock are entitled to receive, when, as and if declared
by the 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, the
Company may pay dividends, at its option, in cash or in additional fully paid
and nonassessable 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. The Company may pay dividends in cash during the period on or
before January 15, 2003 on the Senior Preferred Stock only if it 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, dividends may be paid only in cash. However, the
Senior Note Indenture, the certificate of designation for the Senior Preferred
Stock and the Credit Facilities restrict the payment of cash dividends by the
Company, 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 shall share dividends PRO RATA 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
 
    The Preferred Stock may be redeemed (subject to contractual and other
restrictions with respect thereto and to the legal availability of funds
therefor) at any time on or after January 15, 2003, at the Company's 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 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.

<PAGE>
    In addition, on or prior to January 15, 2001, the Company 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 its Common Stock, PROVIDED that 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.
 
    The Company will not exercise its optional redemption rights provided in the
certificate of designation with respect to the Senior Preferred Stock unless it
contemporaneously redeems the Preferred Stock pro rata.
 
    No optional redemption may be authorized or made unless prior thereto full
unpaid cumulative dividends shall have been paid or a sum set apart for such
payment on the Preferred Stock.
 
    In the event of partial redemptions of Preferred Stock, the shares to be
redeemed will be determined PRO RATA or by lot, as determined by the Company,
except that the Company may redeem such 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 the Company's 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." Notice of redemption will be mailed by
first-class mail to each holder's registered address at least 30 but no more
than 60 days prior to the redemption date. If any Preferred Stock is to be
redeemed in part, the notice of redemption that related to such Preferred Stock
shall state the portion of the liquidation preference to be redeemed. New shares
of Preferred Stock having an aggregate liquidation preference equal to the
unredeemed portion will be issued in the name of the holder thereof upon
cancellation of the original Preferred Stock and, unless the Company fails 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
 
    The Preferred Stock is subject to mandatory redemption (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, the Company will be required
(subject to any contractual and other restrictions with respect thereto existing
on the Closing Date and the legal availability of funds therefor) to make an
Offer to Purchase (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 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, the Company shall not be required to make a
Change of Control Offer if any Indebtedness outstanding on the Closing Date
which 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
 
                                      111
<PAGE>
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.
 
    None of the provisions in the Certificate of Designation relating to a
purchase upon a Change of Control are waivable by the Board of Directors. The
Company could, in the future, enter into certain transactions, including certain
recapitalizations of the Company, 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, the Company 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 the Company would have sufficient
funds to pay the purchase price for all Preferred Stock that the Company would
be required to purchase. In the event that the Company were required to purchase
outstanding Preferred Stock pursuant to a Change of Control Offer, the Company
expects that it would need to seek third-party financing to the extent it does
not have available funds to meet its purchase obligations. However, there can be
no assurance that the Company would be able to obtain such financing. In
addition, the Company's ability to purchase the Preferred Stock may be limited
by other then-existing agreements and by restrictions imposed by Oklahoma law.
 
LIQUIDATION PREFERENCE
 
    Upon any voluntary or involuntary liquidation, dissolution or winding-up of
the Company, holders of Preferred Stock will be entitled to be paid, out of the
assets of the Company 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, the Class A
Preferred Stock, the Class D Preferred Stock, the Class E Preferred Stock, the
Class F Preferred Stock, the Class G Preferred Stock, the Class H Preferred
Stock and the Common Stock of the Company. However, in a bankruptcy proceeding
commenced by or against the Company under the U.S. Bankruptcy Code, the claim of
a holder of Preferred Stock may be limited to the sum of (i) the initial
offering price and (ii) 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 any
voluntary or involuntary liquidation, dissolution or winding-up of the Company,
the amounts payable with respect to the Preferred Stock and all other Parity
Securities are not paid in full, the holders of the Preferred Stock and the
Parity Securities will share equally and ratably in any distribution of assets
of the Company 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 assets of the Company. However, a
merger, consolidation or sale of all or substantially all of the assets of the
Company that complies with the provisions described below under
"--Consolidation, Merger and Sale of Assets" shall not be deemed to be a
liquidation, dissolution or winding-up of the Company.
 
    The Certificate of Designation does not contain any provision requiring
funds to be set aside 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, the Company is not aware of
any provision of Oklahoma law or any controlling decision of the courts of the
State of Oklahoma (the state of incorporation of the Company) that requires a
restriction upon the surplus of the Company solely because the liquidation
preference of the Preferred Stock will exceed its par value. Consequently, there
will be no restriction upon the surplus of the Company 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 the liquidation
of the Company, solely by reason of the fact that such dividend would reduce the
surplus of the Company 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) the Company fails to
discharge any redemption obligation with respect to the Preferred Stock, (c) the
Company fails 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 notice thereof to
the Company by holders of 25% or more of the shares of Preferred Stock then
outstanding or (e) there occurs with respect to any issue or issues of
Indebtedness of the Company and/or any Significant Subsidiary having an
outstanding principal amount of $10 million or more in the aggregate for all
such issues of the Company and/or any Significant Subsidiary, whether such
Indebtedness now exists or shall hereafter be created, (i) an event of default
that has caused the holder thereof to declare such Indebtedness to be due and
payable prior to its Stated Maturity and such Indebtedness has not been
discharged in full or such acceleration has not been rescinded or annulled
within 30 days of such acceleration and/or (ii) the failure to make a principal
payment at the final (but not any interim) fixed maturity and such defaulted
payment shall not have been made, waived or extended within 30 days of such
payment default, 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 the Company becomes aware of the
occurrence of any default referred to in clause (d) or (e) above, the Company
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 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," the Company 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 the Company 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
 
                                      113
<PAGE>
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, (a)
the creation, authorization or issuance of any shares of Junior Securities,
Parity Securities or Senior Securities or (b) 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.
 
CERTAIN DEFINITIONS
 
    Set forth below is a summary of certain of the defined terms used in the

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 the Company or any Restricted Subsidiary; (v) 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 (vi)
contained in the terms of (A) the DOC Facility Agreement or the DCOC Facility
Agreement, PROVIDED any encumbrance or restriction that would prevent payments
of dividends or other distributions to the Company to pay cash interest on the
Exchange Debentures or cash dividends on the Preferred Stock applies on or prior
to January 15, 2003, or applies thereafter only in the event of an event of
default (other than an event of default resulting solely from a breach of a
representation or warranty) under the DOC Facility Agreement or the DCOC
Facility Agreement; PROVIDED (x) with respect to any event of default (other
than a payment default (including by way of acceleration), 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 (y) 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 the Company 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 of a
Restricted Subsidiary, or any agreement pursuant to which such Indebtedness was
issued, if the encumbrance or restriction applies only in the event of a payment
default or a default with respect to a financial covenant contained in such
Indebtedness or agreement, if the encumbrance or restriction is not materially
more disadvantageous to the Holders of the Preferred Stock than is customary in
comparable financings (as determined by the Company) and if the Company
determines that any such encumbrance or restriction will not materially affect
the Company's ability to make dividend payments on the Preferred Stock or
principal or interest payments on the Exchange Debentures. Nothing contained in
this "Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries" covenant shall prevent the Company or any Restricted Subsidiary
from (1) creating, incurring, assuming or suffering to exist any Liens otherwise
permitted in the "Limitation on Liens" covenant or (2) restricting the sale or
other disposition of property or assets of the Company or any of its Restricted
Subsidiaries that secure Indebtedness of the Company or any of its Restricted
Subsidiaries.
 
    LIMITATION ON THE ISSUANCE AND SALE OF CAPITAL STOCK OF RESTRICTED
  SUBSIDIARIES
 
    The Company will not sell, and will not permit any Restricted Subsidiary,
directly or indirectly, to issue or sell, any shares of Capital Stock of a
Restricted Subsidiary (including options, warrants or other rights to purchase
shares of such Capital Stock) except (i) to the Company or a Wholly Owned
Restricted Subsidiary; (ii) issuances of director's qualifying shares or sales
to foreign nationals of shares of Capital
 
                                      129
<PAGE>
Stock of foreign Restricted Subsidiaries, to the extent required by applicable
law; (iii) if, immediately after giving effect to such issuance or sale, such
Restricted Subsidiary would no longer constitute a Restricted Subsidiary,
PROVIDED 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
(iv) sales of Common Stock of a Restricted Subsidiary; PROVIDED that the assets
of such Restricted Subsidiary consist solely of assets relating to the Company's
PCS or resale business.
 
    LIMITATION ON TRANSACTIONS WITH STOCKHOLDERS AND AFFILIATES
 
    The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into, renew or extend any transaction (including,
without limitation, the purchase, sale, lease or exchange of property or assets,
or the rendering of any service) with any holder (or any Affiliate of such
holder) of 5% or more of any class of Capital Stock of the Company or with any
Affiliate of the Company or any Restricted Subsidiary, except upon fair and
reasonable terms no less favorable to the Company or such Restricted Subsidiary
than could be obtained, at the time of such transaction or, if such transaction
is pursuant to a written agreement, at the time of the execution of the
agreement providing therefor, in a comparable arm's-length transaction with a
Person that is not such a holder or an Affiliate.
 
    The foregoing limitation does not limit, and shall not apply to (i)
transactions (A) approved by a majority of the disinterested members of the
Board of Directors or (B) for which the Company 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 the Company or
such Restricted Subsidiary from a financial point of view; (ii) any transaction
solely between the Company and any of its Wholly Owned Restricted Subsidiaries
or solely between Wholly Owned Restricted Subsidiaries; (iii) the payment of
reasonable and customary regular fees to directors of the Company who are not
employees of the Company; (iv) any payments or other transactions pursuant to
any tax-sharing agreement between the Company and any other Person with which
the Company files a consolidated tax return or with which the Company is part of
a consolidated group for tax purposes; or (v) any Restricted Payments not
prohibited by the "Limitation on Restricted Payments" covenant. Notwithstanding
the foregoing, any transaction covered by the first paragraph of this
"Limitation on Transactions with Stockholders and Affiliates" covenant and not
covered by clauses (ii) through (v) of this paragraph, the aggregate amount of
which exceeds $2 million in value, must be approved or determined to be fair in
the manner provided for in clause (i)(A) or (B) above.
 
    LIMITATIONS ON SENIOR PREFERRED STOCK
 
    The Company will not (a) exchange any Senior 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 (b) redeem any Senior Preferred Stock unless it will contemporaneously redeem
a pro rata portion of the Preferred Stock.
 
COMMISSION REPORTS AND REPORTS TO HOLDERS
 
    Whether or not the Company is required to file reports with the Commission,
for so long as any Preferred Stock is outstanding, the Company will file with
the Commission all such reports and other information as it would be required to
file with the Commission by Section 13(a) or 15(d) under the Securities Exchange
Act of 1934 if it were subject thereto. The Company 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
 
    The Company will not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its property
and assets (as an entirety or substantially an entirety in one transaction or a
series of related transactions) to any Person or permit any Person to merge with
or into the
 
                                      130
<PAGE>
Company unless: (i) the Company shall be the continuing Person, or the Person
(if other than the Company) formed by such consolidation or into which the
Company is merged or that acquired or leased such property and assets of the
Company shall be a corporation organized and validly existing under the laws of
the United States of America or any jurisdiction thereof and the Preferred Stock
shall be converted into or exchanged for and shall become shares of such
successor company, having in respect of such successor company or resulting
company substantially the same powers, preferences and relative participating,
optional or other special rights and the qualifications, limitations or
restrictions thereon that the Preferred Stock had immediately prior to such
transaction; (ii) 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; (iii) immediately after giving effect to such
transaction on a pro forma basis, the Company, or, if other than the Company,
the successor company or resulting company, as the case may be, shall have a
Consolidated Net Worth equal to or greater than the Consolidated Net Worth of
the Company immediately prior to such transaction; (iv) immediately after giving
effect to such transaction on a pro forma basis the Company, or, if other than
the Company, 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; PROVIDED that this clause (iv) shall not
apply to a consolidation or merger with or into a Wholly Owned Restricted
Subsidiary with a positive net worth; PROVIDED that, in connection with any such
merger or consolidation, no consideration (other than Common Stock in the
surviving Person or the Company) shall be issued or distributed to the
stockholders of the Company; and (v) the Company delivers to the Transfer Agent
an Officers' Certificate (attaching the arithmetic computations to demonstrate
compliance with clauses (iii) and (iv)) and Opinion of Counsel, in each case
stating that such consolidation, merger or transfer complies with this provision
and that all conditions precedent provided for herein relating to such
transaction have been complied with; PROVIDED, HOWEVER, that clauses (iii) and
(iv) above do not apply if, in the good faith determination of the Board of
Directors of the Company, whose determination shall be evidenced by a Board
Resolution, the principal purpose of such transaction is to change the state of
incorporation of the Company and any such transaction shall not have as one of
its purposes the evasion of the foregoing limitations.
 
EXCHANGE
 
    Subject to the "Limitations on Senior Preferred Stock" covenant, the Company
may, at the sole option of the Board of Directors (subject to the legal
availability of funds therefor), exchange all, but not less than all, of the
outstanding Preferred Stock, including any Preferred Stock issued as payment for
dividends, for Exchange Debentures, subject to the conditions set forth in the
next succeeding paragraph. 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. There can
be 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, the
Company shall (a) if necessary to satisfy the condition set forth in clause (B)
in the following paragraph based upon the written advice of counsel to the
Company, file a registration statement with the Commission relating to the
exchange, and (b) if a registration statement is filed with the Commission
pursuant to clause (a), use its best efforts to cause such registration
statement to be declared effective as soon as practicable by the Commission
unless the opinion referred to in clause (B) in the following paragraph shall
have been subsequently delivered.
 
    In order to effectuate such exchange, the Company shall send a written
notice of exchange by mail to each holder of record of Preferred Stock, which
notice shall state (i) that the Company is exchanging the Preferred Stock into
Exchange Debentures pursuant to the Certificate of Designation and (ii) the date
fixed for exchange (the "Exchange Date"), which date shall not be less than 15
days nor more than 60 days following the date on which such notice is mailed
(except as provided in the last sentence of this
 
                                      131
<PAGE>
paragraph). On the Exchange Date, if the conditions set forth in clauses (A)
through (E) below are satisfied and the exchange is permitted under the
Company's then outstanding indebtedness, the Company shall issue Exchange
Debentures in exchange for the Preferred Stock as provided in the next
paragraph, PROVIDED that on the Exchange Date: (A) there shall be legally
available funds sufficient therefor (including, without limitation, legally
available funds sufficient therefor 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 the Company 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 pursuant to such exchange made in accordance with such
exemption, each holder of an Exchange Debenture that is not an Affiliate of the
Company will not be subject to any restrictions imposed by the Securities Act
upon the resale of such Exchange Debenture, and such exemption is relied upon by
the Company for such exchange; (C) the Exchange Debenture Indenture and the
trustee thereunder shall have been qualified under the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act"); (D) immediately after giving
effect to such exchange, no Default or Event of Default (each as defined in the
Exchange Debenture Indenture) would exist under the Exchange Debenture
Indenture; and (E) the Company shall have delivered to the Trustee under the
Exchange Debenture Indenture a written opinion of counsel, dated the date of
exchange, regarding the satisfaction of the conditions set forth in clauses (A),
(B) and (C). In the event that (i) the issuance of the Exchange Debentures is
not permitted on the Exchange Date or (ii) any of the conditions set forth in
clauses (A) through (E) of the preceding sentence are not satisfied on the
Exchange Date, the Company shall use its best efforts to satisfy such conditions
and effect such exchange as soon as practicable.
 
    Upon any exchange pursuant to the preceding paragraph, the 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; PROVIDED
that the Company at its option 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.
Exchange Debentures issued in exchange for Preferred Stock will be 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, PROVIDED
that the Company may, at the sole option of the Board of Directors, subject to
the restrictions in the Senior Note Indenture, the DOC Facility Agreement, the
DCOC Facility Agreement and any of its other then-existing Indebtedness, 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, an amount in cash, to the
extent applicable, equal to the accrued and unpaid dividends to the Exchange
Date, and, if the Company so elects, 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.
 
    The Company 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
 
    The Company has agreed with the Initial Purchaser, for the benefit of the
holders of Old Shares, that the Company will use its best efforts, at its cost,
to file and cause to become effective a registration statement with respect to a
registered offer to exchange the Old Shares for an issue of preferred stock of
the Company (the "New Shares") with terms identical to the Old Shares (the
"Preferred Stock Exchange Offer"). Upon such registration statement being
declared effective, the Company shall offer the New
 
                                      132
<PAGE>
Shares in return for surrender of the Old Shares. Such offer shall 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 Commission do not permit the Company to
effect such an exchange offer, or under certain other circumstances, the Company
shall, at its cost, use its 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. The
Company shall, in the event of such shelf registration, 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. In the event that the Preferred Stock 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 Preferred Stock Exchange Offer
is consummated or such shelf registration statement is declared effective. The
Company anticipates that it will consummate the Preferred Stock Exchange Offer
and that a shelf registration statement will not be required. Holders of Old
Shares who do not participate in the Preferred Stock Exchange Offer may
thereafter hold a less liquid security. Holders of Old Shares will not be named
as selling securityholders in a Preferred Stock 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.
 
    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
 
                                      133
<PAGE>
Certificate or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.
 
    The Company expects 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. The
Company also expects 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.
 
    The Company understands 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.
 
    The Company understands: 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 Company nor the Initial Purchaser will have any
responsibility for the performance by DTC or its respective participants or
indirect participants of its or their respective obligations under the rules and
procedures governing their operations.
 
CERTIFICATED PREFERRED STOCK
 
    If DTC is at any time unwilling or unable to continue as a depositary for
the Restricted Global Preferred Stock Certificate and a successor depositary is
not appointed by the Company within 90 days, the Company will issue certificated
Preferred Stock in exchange for the Restricted Global Preferred Stock
Certificate, which will bear the legend referred to under the heading "Notice to
Investors."

<PAGE>
                     DESCRIPTION OF THE EXCHANGE DEBENTURES
 
    The Exchange Debentures, if issued, will be issued under the Exchange
Debenture Indenture between the Company and United States Trust Company of New
York, as trustee (the "Trustee"), the form of which is available from the
Company 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 Exchange
Debentures will be subject to all such terms, and prospective holders of the
Exchange Debentures are referred to the Exchange Debenture Indenture and the
Trust Indenture Act for a statement of such terms. 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."
 
GENERAL
 
    The Exchange Debentures will be unsecured obligations of the Company, 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). The
Exchange Debentures will be issued 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 senior subordinated obligations of the Company,
subordinated to all existing and future Senior Indebtedness of the Company and
senior to all subordinated obligations of the Company.
 
    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 the
Company's 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. The Company 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 the Exchange Debentures are issued 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 the option of the Company, 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. The Company 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 the Company's 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 unless under special rules for interest holidays the
 
                                      135
<PAGE>
amount of original issue discount is treated as DE MINIMIS. See "Federal Income
Tax Considerations to U.S. Holders."
 
    The Company may, subject to the covenants described below under "Covenants"
and applicable law, issue additional Exchange Debentures under the Exchange
Debenture Indenture. Exchange Debentures issued in exchange for Preferred Stock
and any additional Exchange Debentures subsequently issued would be treated as a
single class for all purposes under the Exchange Debenture Indenture.
 
SUBORDINATION
 
    The Exchange Debentures will be 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 existing and future
Senior Indebtedness of the Company and senior to the prior payment when due of
the principal of, and premium, if any, and accrued and unpaid interest on, all
subordinated Indebtedness of the Company.
 
    Upon (a) any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property or
(b) an assignment for the benefit of creditors or any marshalling of the
Company's 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, the Company 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 (i) the date upon which the default
is cured or waived or (ii) 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.
 
    The Exchange Debenture Indenture will further require that the Company
promptly notify holders of Senior Indebtedness if payment on the Exchange

    LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
     SUBSIDIARIES
 
    The Company will not, and will not permit any Restricted Subsidiary to,
create or otherwise cause or suffer to exist or become effective any consensual
encumbrance or restriction of any kind on the ability of any Restricted
Subsidiary to (i) pay dividends or make any other distributions permitted by
applicable law on any Capital Stock of such Restricted Subsidiary owned by the
Company or any other Restricted Subsidiary, (ii) pay any Indebtedness owed to
the Company or any other Restricted Subsidiary, (iii) make loans or advances to
the Company or any other Restricted Subsidiary or (iv) transfer any of its
property or assets to the Company or any other Restricted Subsidiary.
 
    The foregoing provisions shall not restrict any encumbrances or
restrictions: (i) 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 (vi) 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; (ii)
existing under or by reason of applicable law; (iii) existing with respect to
any Person or the property or assets of such Person acquired by the Company 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; (iv) in the case of
clause (iv) 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
the Company 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 the Company or any Restricted Subsidiary;
(v) 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 (vi) contained in the terms of (A) the DOC Facility Agreement or
the DCOC Facility Agreement, PROVIDED any encumbrance or restriction that would
prevent payments of dividends or other distributions to the Company 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 an event
of default resulting solely from a breach of a representation or warranty) under
the DOC Facility Agreement or the DCOC Facility Agreement, respectively;
PROVIDED (x) with respect to any event of default (other than a payment default
(including by way of acceleration), 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 (y) 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 the
Company 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 of a Restricted Subsidiary, or any
agreement pursuant to
 
                                      153
<PAGE>
which such Indebtedness was issued, if the encumbrance or restriction applies
only in the event of a payment default or a default with respect to a financial
covenant contained in such Indebtedness or agreement, if the encumbrance or
restriction is not materially more disadvantageous to the Holders of the
Exchange Debentures than is customary in comparable financings (as determined by
the Company) and if the Company 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. Nothing contained in this
"Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries" covenant shall prevent the Company or any Restricted Subsidiary
from (1) creating, incurring, assuming or suffering to exist any Liens otherwise
permitted in the "Limitation on Liens" covenant or (2) restricting the sale or
other disposition of property or assets of the Company or any of its Restricted
Subsidiaries that secure Indebtedness of the Company or any of its Restricted
Subsidiaries.
 
    LIMITATION ON THE ISSUANCE AND SALE OF CAPITAL STOCK OF RESTRICTED
     SUBSIDIARIES
 
    The Company will not sell, and will not permit any Restricted Subsidiary,
directly or indirectly, to issue or sell, any shares of Capital Stock of a
Restricted Subsidiary (including options, warrants or other rights to purchase
shares of such Capital Stock) except (i) to the Company or a Wholly Owned
Restricted Subsidiary; (ii) 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; (iii) if, immediately
after giving effect to such issuance or sale, such Restricted Subsidiary would
no longer constitute a Restricted Subsidiary, PROVIDED 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 (iv) sales of Common Stock of a
Restricted Subsidiary; PROVIDED that the assets of such Restricted Subsidiary
consist solely of assets relating to the Company'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
 
    The Company will not permit any Restricted Subsidiary, directly or
indirectly, to Guarantee any Indebtedness of the Company which is PARI PASSU
with or subordinate in right of payment to the Exchange Debentures ("Guaranteed
Indebtedness"), unless (i) 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 (ii) 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; PROVIDED
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 is (A) PARI
PASSU with the Exchange Debentures, then the Guarantee of such Guaranteed
Indebtedness shall be PARI PASSU with, or subordinated to, the Subsidiary
Guarantee or (B) 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.
 
    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 (i) any sale, exchange or transfer,
to any Person not an Affiliate of the Company, of all of the Company'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 (ii) the
 
                                      154
<PAGE>
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
 
    The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into, renew or extend any transaction (including,
without limitation, the purchase, sale, lease or exchange of property or assets,
or the rendering of any service) with any holder (or any Affiliate of such
holder) of 5% or more of any class of Capital Stock of the Company or with any
Affiliate of the Company or any Restricted Subsidiary, except upon fair and
reasonable terms no less favorable to the Company or such Restricted Subsidiary
than could be obtained, at the time of such transaction or, if such transaction
is pursuant to a written agreement, at the time of the execution of the
agreement providing therefor, in a comparable arm's-length transaction with a
Person that is not such a holder or an Affiliate.
 
    The foregoing limitation does not limit, and shall not apply to (i)
transactions (A) approved by a majority of the disinterested members of the
Board of Directors or (B) for which the Company or a Restricted Subsidiary
delivers to the Trustee a written opinion of a nationally recognized investment
banking firm stating that the transaction is fair to the Company or such
Restricted Subsidiary from a financial point of view; (ii) any transaction
solely between the Company and any of its Wholly Owned Restricted Subsidiaries
or solely between Wholly Owned Restricted Subsidiaries; (iii) the payment of
reasonable and customary regular fees to directors of the Company who are not
employees of the Company; (iv) any payments or other transactions pursuant to
any tax-sharing agreement between the Company and any other Person with which
the Company files a consolidated tax return or with which the Company is part of
a consolidated group for tax purposes; or (v) any Restricted Payments not
prohibited by the "Limitation on Restricted Payments" covenant. Notwithstanding
the foregoing, any transaction covered by the first paragraph of this
"Limitation on Transactions with Stockholders and Affiliates" covenant and not
covered by clauses (ii) through (v) of this paragraph, the aggregate amount of
which exceeds $2 million in value, must be approved or determined to be fair in
the manner provided for in clause (i)(A) or (B) above.
 
    LIMITATION ON ASSET SALES
 
    The Company will not, and will not permit any Restricted Subsidiary to,
consummate any Asset Sale, unless (i) the consideration received by the Company
or such Restricted Subsidiary is at least equal to the fair market value of the
assets sold or disposed of and (ii) at least 85% of the consideration received
consists of cash or Temporary Cash Investments. In the event and to the extent
that the Net Cash Proceeds received by the Company or any of its Restricted
Subsidiaries from one or more Asset Sales occurring on or after the Closing Date
in any period of 12 consecutive months exceed 10% of Adjusted Consolidated Net
Tangible Assets (determined as of the date closest to the commencement of such
12-month period for which a consolidated balance sheet of the Company and its
subsidiaries has been filed pursuant to the "Commission Reports and Reports to
Holders" covenant), then the Company shall or shall cause the relevant
Restricted Subsidiary to (i) within 12 months after the date Net Cash Proceeds
so received exceed 10% of Adjusted Consolidated Net Tangible Assets (A) apply an
amount equal to such excess Net Cash Proceeds to permanently repay Senior
Indebtedness of the Company or any Restricted Subsidiary providing a Subsidiary
Guarantee pursuant to the "Limitation on Issuances of Guarantees by Restricted
Subsidiaries" covenant described above or Indebtedness of any other Restricted
Subsidiary, in each case owing to a Person other than the Company or any of its
Restricted Subsidiaries or (B) invest an equal amount, or the amount not so
applied pursuant to clause (A) (or enter into a definitive agreement committing
to so invest within 12 months after the date of such agreement), in property or
assets (other than current assets) of a nature or type or that are used in a
business (or in a company having property and assets of a nature or type, or
engaged in a business) similar or related to the nature or type of the property
 
                                      155
<PAGE>
and assets of, or the business of, the Company and its Restricted Subsidiaries
existing on the date of such investment and (ii) apply (no later than the end of
the 12-month period referred to in clause (i)) such excess Net Cash Proceeds (to
the extent not applied pursuant to clause (i)) as provided in the following
paragraph of this "Limitation on Asset Sales" covenant. The amount of such
excess Net Cash Proceeds required to be applied (or to be committed to be
applied) during such twelve-month period as set forth in clause (i) of the
preceding sentence and not applied as so required by the end of such period
shall constitute "Excess Proceeds."
 
    If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
"Limitation on Asset Sales" covenant totals at least $5 million, the Company
must commence, not later than the fifteenth Business Day of such month, and
consummate an Offer to Purchase from the Holders on a pro rata basis an
aggregate principal amount of 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
 
    The Company will not (a) pay interest in cash on the Senior Exchange
Debentures unless it will contemporaneously pay interest in cash on the Exchange
Debentures or (b) 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
 
    The Company 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 the Company 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 the Company which
might be outstanding at the time). The above covenant requiring the Company to
repurchase the Exchange Debentures will, unless consents are obtained, require
the Company to repay all indebtedness then outstanding which by its terms would
prohibit such Exchange Debenture repurchase, either prior to or concurrently
with such Exchange Debenture repurchase.
 
COMMISSION REPORTS AND REPORTS TO HOLDERS
 
    Whether or not the Company is required to file reports with the Commission,
for so long as any Exchange Debentures are outstanding, the Company 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
Securities Exchange Act of 1934 if it were subject thereto. The Company shall
supply the Trustee and each Holder or shall supply to the Trustee for forwarding
to each such Holder, without cost to such Holder, copies of such reports and
other information.
 
EVENTS OF DEFAULT
 
    The following events will be defined as "Events of Default" in the Exchange
Debenture Indenture: (a) default in the payment of principal of (or premium, if
any, on) any Exchange Debenture when the same becomes due and payable at
maturity, upon acceleration, redemption or otherwise, whether or not such
payment is prohibited by the provisions described above under "--Ranking"; (b)
default in the payment of interest on any Exchange Debenture when the same
becomes due and payable, and such default continues for a period of 30 days,
whether or not such payment is prohibited by the provisions described above
under
 
                                      156
<PAGE>
"--Ranking"; (c) default in the performance or breach of the provisions of the
Exchange Debenture Indenture applicable to mergers, consolidations and transfers
of all or substantially all of the assets of the Company or the failure to make
or consummate an Offer to Purchase in accordance with the "Limitation on Asset
Sales" or "Repurchase of Exchange Debentures upon a Change of Control" covenant;
(d) the Company defaults in the performance of or breaches any other covenant or
agreement of the Company in the Exchange Debenture Indenture or under the
Exchange Debentures (other than a default specified in clause (a), (b) or (c)
above) and such default or breach continues for a period of 30 consecutive days
after written notice by the Trustee or the Holders of 25% or more in aggregate
principal amount of the Exchange Debentures; (e) there occurs with respect to
any issue or issues of Indebtedness of the Company or any Significant Subsidiary
having an outstanding principal amount of $10 million or more in the aggregate
for all such issues of all such Persons, whether such Indebtedness now exists or
shall hereafter be created, (I) an event of default that has caused the holder
thereof to declare such Indebtedness to be due and payable prior to its Stated
Maturity and such Indebtedness has not been discharged in full or such
acceleration has not been rescinded or annulled within 30 days of such
acceleration and/or (II) the failure to make a principal payment at the final
(but not any interim) fixed maturity and such defaulted payment shall not have
been made, waived or extended within 30 days of such payment default; (f) any
final judgment or order (not covered by insurance) for the payment of money in
excess of $10 million in the aggregate for all such final judgments or orders
against all such Persons (treating any deductibles, self-insurance or retention
as not so covered) shall be rendered against the Company or any Significant
Subsidiary and shall not be paid or discharged, and there shall be any period of
30 consecutive days following entry of the final judgment or order that causes
the aggregate amount for all such final judgments or orders outstanding and not
paid or discharged against all such Persons to exceed $10 million during which a
stay of enforcement of such final judgment or order, by reason of a pending
appeal or otherwise, shall not be in effect; (g) a court having jurisdiction in
the premises enters a decree or order for (A) relief in respect of the Company
or any Significant Subsidiary in an involuntary case under any applicable
bankruptcy, insolvency or other similar law now or hereafter in effect, (B)
appointment of a receiver, liquidator, assignee, custodian, trustee,
sequestrator or similar official of the Company or any Significant Subsidiary or
for all or substantially all of the property and assets of the Company or any
Significant Subsidiary or (C) the winding up or liquidation of the affairs of
the Company or any Significant Subsidiary and, in each case, such decree or
order shall remain unstayed and in effect for a period of 30 consecutive days;
or (h) the Company or any Significant Subsidiary (A) commences a voluntary case
under any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect, or consents to the entry of an order for relief in an
involuntary case under any such law, (B) consents to the appointment of or
taking possession by a receiver, liquidator, assignee, custodian, trustee,
sequestrator or similar official of the Company or any Significant Subsidiary or
for all or substantially all of the property and assets of the Company or any
Significant Subsidiary or (C) effects any general assignment for the benefit of
creditors.
 
    If an Event of Default (other than an Event of Default specified in clause
(g) or (h) above that occurs with respect to the Company) occurs and is
continuing under the 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 the Company (and to the Trustee if such notice
is given by the Holders), may, and the Trustee at the request of such Holders
shall, declare the principal of, premium, if any, and accrued interest on the
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 PROVIDED 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 (i) five Business Days after the receipt of the
acceleration notice by the agents thereunder and the Company and (ii)
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 (e) above has occurred and is
continuing,
 
                                      157
<PAGE>
such declaration of acceleration shall be automatically rescinded and annulled
if the event of default triggering such Event of Default pursuant to clause (e)
shall be remedied or cured by the Company or the relevant Significant Subsidiary
or waived by the holders of the relevant Indebtedness within 60 days after the
declaration of acceleration with respect thereto. If an Event of Default
specified in clause (g) or (h) above occurs with respect to the Company, the
principal of, premium, if any, and accrued interest on the Exchange Debentures
then outstanding shall IPSO FACTO become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder.
At any time after declaration of acceleration, but before a judgment or decree
for the payment of the money due has been obtained by the Trustee, the Holders
of at least a majority in principal amount of the outstanding Exchange
Debentures by written notice to the Company and to the Trustee, may waive all
past defaults and rescind and annul a declaration of acceleration and its
consequences if (i) all existing Events of Default, other than the nonpayment of
the principal of, premium, if any, and interest on the Exchange Debentures that
have become due solely by such declaration of acceleration, have been cured or
waived and (ii) the rescission would not conflict with any judgment or decree of
a court of competent jurisdiction. For information as to the waiver of defaults,
see "--Modification and Waiver."
 
    The Holders of at least a majority in aggregate principal amount of the
outstanding 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: (i) the Holder gives the Trustee written notice of a
continuing Event of Default; (ii) the Holders of at least 25% in aggregate
principal amount of outstanding Exchange Debentures make a written request to
the Trustee to pursue the remedy; (iii) such Holder or Holders offer the Trustee
indemnity satisfactory to the Trustee against any costs, liability or expense;
(iv) the Trustee does not comply with the request within 60 days after receipt
of the request and the offer of indemnity; and (v) during such 60-day period,
the Holders of a majority in aggregate principal amount of the outstanding
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 the Company 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 (i) the initial price of the Exchange Debentures and (ii)
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 the Company to
certify, on or before a date not more than 90 days after the end of each fiscal
year, that a review has been conducted of the activities of the Company and its
Restricted Subsidiaries and the Company's and its Restricted Subsidiaries'
performance under the Exchange Debenture Indenture and that the Company has
fulfilled all obligations thereunder, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default and the nature
and status thereof. The Company will also be obligated to notify the Trustee of
any default or defaults in the performance of any covenants or agreements under
the Exchange Debenture Indenture.

which the Company is merged or that acquired or leased such property and assets
of the Company shall be a corporation organized and validly existing under the

continuing; (iii) immediately after giving effect to such transaction on a pro
forma basis, the Company or any Person becoming the successor obligor of the
Exchange Debentures shall have a Consolidated Net Worth equal to or greater than
the Consolidated Net Worth of the Company immediately prior to such transaction;
(iv) immediately after giving effect to such transaction on a pro forma basis
the Company, 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; PROVIDED that
this clause (iv) shall not apply to a consolidation or merger with or into a
Wholly Owned Restricted Subsidiary with a positive net worth; PROVIDED that, in
connection with any such merger or consolidation, no consideration (other than
Common Stock in the surviving Person or the Company) shall be issued or
distributed to the stockholders of the Company; and (v) the Company delivers to
the Trustee an Officers' Certificate (attaching the arithmetic computations to

the good faith determination of the Board of Directors of the Company, whose
determination shall be evidenced by a Board Resolution, the principal purpose of
such transaction is to change the state of incorporation of the Company and any
such transaction shall not have as one of its purposes the evasion of the
foregoing limitations.

Indenture and the Exchange Debentures, (B) the Company has delivered to the
Trustee (i) either (x) an Opinion of Counsel to the effect that Holders will not
recognize income, gain or loss for federal income tax purposes as a result of
the Company's exercise of its option under this "Defeasance" provision and will
be subject to federal income tax on the same amount and in the same manner and
at the same times as would have been the case if such deposit, defeasance and
discharge had not occurred, which Opinion of Counsel must be based upon (and
accompanied by a copy of) a ruling of the Internal Revenue Service to the same
effect unless there has been a change in applicable federal income tax law after
the Closing Date such that a ruling is no longer required or (y) a ruling
directed to the Trustee received from the Internal Revenue Service to the same
 
                                      159
<PAGE>
effect as the aforementioned Opinion of Counsel and (ii) an Opinion of Counsel
to the effect that the creation of the defeasance trust does not violate the
Investment Company Act of 1940 and after the passage of 123 days following the
deposit (except with respect to any trust funds for the account of any Holder
who may be deemed an "insider" for purposes of the United States Bankruptcy
Code, after one year following the deposit); the trust funds will not be subject
to the effect of Section 547 of the United States Bankruptcy Code or Section 15
of the New York Debtor and Creditor Law, (C) immediately after giving effect to
such deposit on a pro forma basis, no Default or Event of Default shall have
occurred and be continuing on the date of such deposit or during the period
ending on the 123rd day after the date of such deposit, and such deposit shall
not result in a breach or violation of, or constitute a default under, any other
agreement or instrument to which the Company or any of its Subsidiaries is a
party or by which the Company or any of its Subsidiaries is bound, (D) the
Company is not prohibited from making payments in respect of the Exchange
Debentures by the provisions described above under "--Ranking" and (E) 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 (iii)
and (iv) under "Consolidation, Merger and Sale of Assets" and all the covenants
described herein under "Covenants," clauses (c) and (d) under "Events of
Default" with respect to such clauses (iii) and (iv) under "Consolidation,
Merger and Sale of Assets" and such covenants and clauses (e) and (f) under
"Events of Default" shall be deemed not to be Events of Default, upon, among
other things, the deposit with the Trustee, in trust, of money and/or U.S.
Government Obligations that through the payment of interest and principal in
respect thereof in accordance with their terms will provide money in an amount
sufficient to pay the principal of, premium, if any, and accrued interest on the
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)(ii), (C), (D) and (E) of

Opinion of Counsel to the effect that, among other things, the Holders will not
recognize income, gain or loss for federal income tax purposes as a result of
such deposit and defeasance of certain covenants and Events of Default and will
be subject to federal income tax on the same amount and in the same manner and
at the same times as would have been the case if such deposit and defeasance had
not occurred.
 
    DEFEASANCE AND CERTAIN OTHER EVENTS OF DEFAULT.  In the event the Company
exercises its option to omit compliance with certain covenants and provisions of
the 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, the Company will
remain liable for such payments.
 
MODIFICATION AND WAIVER
 
    Modifications and amendments of the Exchange Debenture Indenture may be made
by the Company and the Trustee with the consent of the holders of not less than
a majority in aggregate principal amount of the outstanding Exchange Debentures;
PROVIDED, HOWEVER, that no such modification or amendment may, without the
consent of each holder affected thereby, (i) change the Stated Maturity of the
principal of, or any installment of interest on, any Exchange Debenture, (ii)
reduce the principal amount of, premium, if any, or interest on, any Exchange
Debenture, (iii) change the place or currency of payment of principal of
premium, if any, or interest on, any Exchange Debenture, (iv) impair the right
to institute suit for the enforcement of any payment on or after the Stated
Maturity (or, in the case of a redemption, on or after
 
                                      160
<PAGE>
the Redemption Date) of any Exchange Debenture, (v) modify the subordination
provisions in a manner adverse to the holders in any material respect, (vi)
reduce the above-stated percentage of outstanding Exchange Debentures the
consent of whose holders is necessary to modify or amend the Exchange Debenture
Indenture, (vii) waive a default in the payment of principal of, premium, if
any, or interest on, the Exchange Debentures, (viii) modify any of the
provisions of the Exchange Debenture Indenture described under "--Ranking" in a
manner adverse to the Holders, or (ix) 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
the Company 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 the Company. 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 the Company, to obtain payment of claims in certain
cases or to realize on certain property received by it in respect of any such
claims, as security or otherwise. The Trustee is permitted to engaged in other
transactions; PROVIDED, HOWEVER, that if it acquires any conflicting interest,
it must eliminate such conflict or resign.

NEW CREDIT FACILITIES
 
    The New 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 $400.0 million
("Term Loan Facilities") to be used for permitted acquisitions, restricted
payments, the Sygnet Acquisition, to refinance Sygnet's existing indebtedness
and to fund, capital expenditures, permitted investments, working capital and
other corporate purposes.
 
    The following summary of the material provisions of the New 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 New Credit Facilities aggregate $430.0 million and include (a) a $50.0
million, 7 3/4 year reducing revolving credit facility, (b) a $125.0 million,
7 3/4 year term loan ("Term Loan A"), (c) a $155.0 million, 8 1/4 year term loan
("Term Loan B"), and (d) a $100.0 million, 9 year term loan ("Term Loan C").
 
    Borrowings under the Revolving Credit Facility and Term Loans A and B bear
interest payable at least quarterly, at Sygnet's option, at (a) the "Applicable
Margin" plus the greater of (i) the Federal Funds Effective Rate plus 0.5% and
(ii) the prime rate (the "Base Rate"), or (b) the "Applicable Margin" plus
Reserve Adjusted LIBOR ("LIBOR") for interest periods of 1, 2, 3 or 6 months.
The "Applicable Margin" for the Revolving Credit Facility and Term Loan A
fluctuates based on Sygnet's leverage and is the Base Rate plus 0.75% to 2.00%
or LIBOR plus 1.75% to 3.00%. For Term Loan B, the "Applicable Margin"
fluctuates based on Sygnet's leverage and is the Base Rate plus 1.75% to 2.25%
or LIBOR plus 2.75% to 3.25%. Term Loan C 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 New Credit Facilities will be permanently reduced
by an amount equal to 100% of the net cash proceeds from sales of assets in
excess of $5.0 million, to the extent not reinvested within 12 months, by an
amount equal to 100% of the net cash proceeds received from certain equity or
debt issuances and by 75% or 50% of excess cash flow, depending on Sygnet's
leverage. In addition, to the extent amounts have been borrowed in respect of
the Tower Sale Leaseback, such amounts shall be repaid with the net proceeds
therefrom and the commitments under each of Term Loan A and Term Loan B will
decrease by $10.0 million.
 
    Sygnet may, without premium or penalty, prepay advances bearing interest
based on the Base Rate at any time and may, without premium or penalty, prepay
advances bearing interest based on the LIBOR rate at the end of an applicable
interest period. Term Loan C may be redeemed in whole or in part at 102% of the
principal amount through December 31, 1999, 101% of the principal amount through
December 31, 2001 and thereafter at 100%.
 
    The New 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 New Credit Facilities will contain
other usual and customary negative and affirmative covenants, including Year
2000 compliance.
 
    The New Credit Facilities restrict Sygnet and Sygnet Communications from
declaring and paying distributions or making restrictive payments. However,
Sygnet will be permitted to pay dividends to pay (i) scheduled interest on the
Dobson/Sygnet Notes commencing after the first six interest payments on the
Dobson/Sygnet Notes and (ii) regularly scheduled payments on up to $120,000,000
in liquidation preference value of Dobson's preferred stock, commencing January
15, 2003, in each case unless if at the time of such dividend or distribution an
event of default (other than an event of default resulting solely from the
breach of a representation or warranty) exists or would be caused by such
dividend or distribution; provided that, with respect to any event of default
(other than a payment default (including by way of acceleration), a bankruptcy
event with respect to Sygnet or Sygnet Communications or the Company or any of
its restricted subsidiaries or the loss of a material license or cellular
system), Sygnet Communications will not be prohibited from paying dividends to
Sygnet to pay scheduled interest on the Dobson/ Sygnet Notes for more than 180
days.
 
    Sygnet will be required to maintain certain financial ratios, including,
among others, a ratio of total debt to cash flow, a ratio of operating cash flow
to pro forma debt service, a ratio of operating cash flow to cash interest
expense and a fixed charge coverage ratio. In addition, the Company and Sygnet
will be required to maintain a ratio of debt to operating cash flow.
 
    Failure to satisfy any of the financial covenants will constitute an Event
of Default under the New 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 New Credit Facilities will 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 the Company or any of its
subsidiaries; cross default to other material indebtedness, leases, contracts of
Sygnet, its subsidiaries, or of the Company and its subsidiaries (excluding
Logix); any material adverse change; dissolution or termination of Sygnet or any
of its subsidiaries or of the Company; if the Company fails to maintain direct
voting and economic

control of Sygnet and its subsidiaries; and if less than two-thirds of the
existing executive management team of the Company continue to hold executive
positions with the Company.
 
    Sygnet's obligations under the New Credit Facilities will be guaranteed by
its subsidiaries. Borrowings under the New Credit Facilities will be secured by
a first perfected security interest in all assets of Sygnet and its present and
future subsidiaries including a pledge of all intercompany notes.
 
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, mature on December
22, 1999 364 days after closing and bears interest at a fixed rate of 8.0% per
annum.
 
    The credit agreement governing the Tower Credit Facility requires, 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 FACILITY
 
    The Company's DOC 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 Facility does not purport to be
complete and is subject to, and is qualified in its entirety by reference to,
the DOC 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 Facility matures on June 30, 2006. Borrowings under the DOC Facility
bear interest, payable at least quarterly, at DOC's option, at an annual rate
equal to either (i) the greater of (x) the federal funds rate plus 1/2% and (y)
the prime rate of NationsBank, plus in each case a percentage per annum ranging
from 0% to 1(1)%, or (ii) 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 the Company'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%
 
    Commencing with the quarter ending June 30, 2000, the borrowing commitment
under the DOC 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 the
Company must be used to repay borrowings under the DOC Facility and reduce the
borrowing commitment thereunder.
 
    The DOC Facility contains a number of covenants including, among others,
covenants limiting the ability of the Company, DOC and DOC's Restricted
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 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 the
Total Leverage Ratio of the Company (including Restricted and Unrestricted
Subsidiaries) is greater than 8.5 to 1 (giving pro forma effect to the
acquisition). The DOC Facility contains other customary affirmative covenants.
 
    The DOC 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
 
                                      164
<PAGE>
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 the Company 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; PROVIDED that, with respect to any event of default (other than a
payment default (including by way of acceleration), a bankruptcy event with
respect to the Company or DOC or the loss of a material license or cellular
system), DOC will not be prohibited from paying dividends to the Company 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 the Company of 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); PROVIDED, 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 the Company 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.
 
    The Company is required to comply with certain financial tests and maintain
certain financial ratios, including, among others, a requirement that (i) 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, (ii) the ratio of DOC's
Operating Cash Flow to its Pro Forma Debt Service exceed 1.15 to 1; (iii) the

Company's Consolidated Operating Cash Flow to its Consolidated Interest Expense
for the most recently ended four quarters exceed 1.25 to 1.
 
    For purposes of the financial covenants, "Operating Cash Flow" for DOC is
defined as Operating Cash Flow of DOC and its Restricted Subsidiaries, including
certain cash flow of the "Cellular Operating Partnerships" (defined as 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 the Company is defined as Operating Cash Flow
of the Company and its Restricted Subsidiaries, in each case for the four most
recently completed quarters. "Operating Cash Flow" for any period is defined as
the (i) sum of pre-tax income, without giving effect to extraordinary losses or
gains, interest, depreciation and amortization expenses and non-cash charges,
minus (ii) interest and dividend income, reductions in deferred taxes and other
non-cash components of income. "Total Debt" of DOC and its Restricted
Subsidiaries is defined as 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 the Company or any subsidiary of
the Company not owned by DOC. "Total Debt" of the Company and its Restricted
Subsidiaries is defined as the sum of all obligations for borrowed money (less
the amount escrowed for interest payments on the Senior Notes), all payments
required under
 
                                      165
<PAGE>
noncompete agreements, capital lease obligations, amounts required under
installment sale purchases, all financial obligations of others guaranteed and
any amounts for which the Company and any of its direct or indirect 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. "Pro Forma Debt Service" is
defined as 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 (the sum of (a) Total Debt at the beginning of the period plus
(b) such Total Debt minus payments scheduled to be made during the period,
divided by two) by the interest rate in effect at the time of calculation.
"Fixed Charge Coverage Ratio" is defined as the ratio of (i) the Operating Cash
Flow of DOC for the most recently ended four quarters to (ii) 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. The
Company's "Total Leverage Ratio" is defined as the ratio of its Total Debt to
its Operating Cash Flow. "Restricted Subsidiaries" is defined as 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 Facility, permitting the lenders, after notice, to
terminate this commitment and/or accelerate payment of outstanding indebtedness
notwithstanding the ability of the Company to meet its debt service obligations.
The DOC 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 Dobson as part
of the senior management team.
 
    DOC's obligations under the DOC Facility are guaranteed by the Company and
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 FACILITY
 
    The DCOC 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 Facility does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, the DCOC 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 Facility loan agreement.
 
    The DCOC Facility includes (a) a $120 million eight and one-half year
reducing revolving credit facility and (b) 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 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
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.
 
                                      166
<PAGE>
    The facilities comprising the DCOC Facility will mature on June 30, 2006.
Borrowings under the DCOC Facility bear interest, payable at least quarterly, at
DCOC's option, at an annual rate equal to either (i) the greater of (x) the
federal funds rate plus 1/2% and (y) the prime rate of NationsBank, plus in each
case a percentage per annum ranging from 1/8% to 1 3/8%, or (ii) 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, the borrowing commitment
under the DCOC 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, 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 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 the Company's 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 Facility contains
other covenants customary for similar credit facilities.
 
    The DCOC 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 the Company 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; PROVIDED that, with respect to any
event of default (other than a payment default (including by way of
acceleration), a bankruptcy event with respect to the Company or DCOC or the
loss of a material license or cellular system), DCOC will not be prohibited from
paying dividends to the Company 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 (i) 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, PROVIDED that 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; (ii) the ratio of DCOC's Operating Cash Flow to its Pro Forma Debt
Service shall exceed 1.25 to 1; (iii) 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
 
                                      167
<PAGE>
December 31, 1998 and 2.0 to 1 thereafter; and (iv) the Fixed Charge Coverage
Ratio be greater than 1.0 to 1.
 
    For purposes of the financial covenants, "Operating Cash Flow" for DCOC
includes the Operating Cash Flow of any "Cellular Operating Partnership"
(defined as 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, except 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 the
definition of DCOC's Operating Cash Flow. Operating Cash Flow for the Company
includes the Operating Cash Flow of the Company and its Restricted Subsidiaries.
"Operating Cash Flow" for any period is defined as the (i) sum of pre-tax
income, without giving effect to any extraordinary losses or gains, interest,
depreciation and amortization expenses and non-cash charges, minus (ii) interest
and dividend income, reductions in deferred taxes and other non-cash components
of income. "Total Debt" of DCOC is defined as 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 any
amounts for which DCOC is contingently liable to provide as equity or debt
advances to other parties, but does not include intercompany subordinated debt
owed by DCOC to the Company. "Total Debt" of the Company and its Restricted
Subsidiaries is defined as 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 the Company and any of its direct or
indirect 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 is 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 defined
as 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 (x) 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 (y) the interest rate in
effect at the time of calculation. "Fixed Charge Coverage Ratio" is defined as
the ratio of (i) DCOC's Operating Cash Flow for the most recently ended four
quarters to (ii) 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 defined as 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 defined as the ratio of its Total Debt to its Operating Cash
Flow. The Company'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 Facility, permitting the lenders, after notice, to
terminate the commitment and/or accelerate payment of outstanding indebtedness
notwithstanding the ability of the Company to meet its debt service obligations.
The DCOC 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, 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 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.

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 the Company's issuance of equity
securities (including rights, options or warrants with respect to such
securities and other securities convertible into equity securities), restrict
the ability of the Company and its 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
 
                                      171
<PAGE>
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 (i) 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, (ii) make any change in the Company's
Certificate of Incorporation which would adversely affect the powers,
preferences or rights, including voting rights, of the Class D Preferred Stock,
(iii) authorize or effect the sale of all or substantially all of the assets of
the Company, any merger or consolidation of the Company resulting in the change
of control, or the liquidation, dissolution or winding up of the Company, (iv)
amend the Company's Certificate of Incorporation or Bylaws to change the
authorized number of directors or (v) 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 will be
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

    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 the liquidation, dissolution or winding
up of the Company 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.
 
    REDEMPTION.  All of the Class D and Class E Preferred Stock must be redeemed
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 by the Company
of an initial public offering of its common stock resulting in gross proceeds of
at least $50.0 million. The obligation of the Company to redeem its 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 by the Company of an
initial public offering of its 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 the Company to purchase its 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 the Company's voting stock
controlled by Everett R. Dobson and his affiliates being less than 50.1% and the
sale of all or substantially all of the Company's capital stock, business or
assets, but shall not include the sale or redemption by the Dobson Partnership
of up to $25.0 million of the Company's capital stock or an initial public
offering by the Company of its common stock. To the extent the Company has cash
available, the Company must pay cash to purchase the Class E Preferred Stock. To
the extent the Company does not have available cash, the Company is 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 the Company has 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 the notes
will mature upon the last to occur of (i) termination of the Credit Facilities,
(ii) termination of the Senior Note Indenture, (iii) the repurchase, payment or
defeasance of the Senior Notes and (iv) 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 an initial public offering of its common stock, the
Company 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. Nothwithstanding the foregoing, in the case of a
Change of
 
                                      173
<PAGE>
Control in which (i) 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
(ii) following an initial public offering, Everett R. Dobson and his affiliates
cease to control at least 35% of the Company's voting stock, the Company may not
pay the holders subordinated notes in lieu of cash.
 
    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 the Company's 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 the Company
securities held by it upon completion of the Equity Investments, in addition to
the director it may designate, Childs may also designate an observer to 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).
 
    The Shareholders will have preemptive rights with respect to new common
stock or securities convertible into common stock issued by the Company
(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 shareholder
of the Company or in a public sale. The transfer restrictions in the Investors
Agreement will terminate upon the earliest of an initial public offering by the
Company, a Change of Control or December 23, 2003.
 
    The Shareholders are obligated to sell their shares of the Company's common
stock, Class D Preferred Stock and Class E Preferred Stock to any unaffiliated
party pursuant to an agreement which (i) treats equally, on an "as-if-converted"
basis, the common value of all holders of the Company's common stock, Class D
Preferred Stock and Class E Preferred Stock, (ii) is approved by the board of
directors of the Company as fair to all stockholders and (iii) is approved by
stockholders of the Company holding 50.1% of the Company's 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 the Company's
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 the Company's outstanding common stock, Class D Preferred Stock and
Class E Preferred Stock by any other stockholder, except in the case of (i) the
sale by the Dobson Partnership of the Company's capital stock for $25.0 million
or less, together with accrued but unpaid dividends thereon, (ii) the sale of
any capital stock issued by the Company in connection with the Sygnet Financing,
or (iii) 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.

Cumulative dividends on each share of Class G Preferred Stock accrue at the
annual rate of 16% on the sum of the $660.40 per share liquidation value, and
all accumulated and unpaid dividends ("Class G Accrued Dividends") from the date
of issuance, compounded annually, are payable out of funds legally available
therefor in cash on the liquidation, dissolution or winding up of the Company or
on redemption.
 
    The Financing Agreements limit, and if exchange debentures are issued for

time, or from time to time, after the Closing Date until the third anniversary
of the Closing Date. On the third anniversary of the Closing Date, any
outstanding shares of Class G Preferred Stock will automatically be converted.
Each share of Class G Preferred Stock is convertible into one share of Class H
Preferred Stock and shares of Class A Common Stock which, if all shares of Class
G Preferred Stock were fully converted, would represent approximately 1.87% of
the Company's then outstanding common stock, on a fully diluted basis.
 
    REDEMPTION.  The Class G Preferred Stock must be redeemed for its
liquidation value, plus Class G Accrued Dividends, within 90 days following the

annually, are payable only upon the liquidation, dissolution or winding up of
the Company or on redemption. Dividends on the Class H Preferred Stock will
cease to accrue, and will not be payable, with respect to any period commencing

               FEDERAL INCOME TAX CONSIDERATIONS TO U.S. HOLDERS
 
    The following summary describes the anticipated material U.S. federal income
tax consequences of the purchase, ownership and disposition of the Preferred
Stock and Exchange Debentures by U.S. Holders (as defined below). Except where
noted, it deals only with Preferred Stock and Exchange Debentures held as
capital assets within the meaning of Section 1221 of the Code and does not
address all aspects of the U.S. federal income tax consequences that may be
relevant to a particular investor or holders subject to special tax rules, such
as dealers in securities or currencies, financial institutions, tax-exempt
organizations, life insurance companies, persons holding Preferred Stock or
Exchange Debentures as a part of a hedging or conversion transaction or a
straddle, or U.S. Holders whose "functional currency" is not the U.S. dollar.
Furthermore, the summary is based upon the provisions of the Code and Treasury
Regulations, including the OID Regulations, rulings and judicial decisions
thereunder as of the date hereof. 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.
 
    Because the Company 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. Holders.
Accordingly, the Company will offer the Preferred Stock only to investors who
are U.S. Holders and the summary does not address the U.S. federal income tax
consequences to investors who are not U.S. Holders. THE COMPANY CONSIDERS THE
PREFERRED STOCK TO BE AN INAPPROPRIATE INVESTMENT FOR ANY PERSON WHO OR WHICH IS
NOT A U.S. HOLDER.
 
   
    PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE
FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP
AND DISPOSITION OF THE PREFERRED STOCK AND EXCHANGE DEBENTURES.

    "Code" means the U.S. Internal Revenue Code of 1986, as amended and in
effect as of the date hereof.

the U.S. 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 (i) a court within the U.S. is able to exercise primary supervision over
the administration of such trust and (ii) one or more U.S. persons have the

PURCHASE, OWNERSHIP AND DISPOSITION OF THE PREFERRED STOCK
 
    DISTRIBUTIONS ON THE PREFERRED STOCK
 
    GENERAL.  Distributions of cash or of additional shares of Preferred Stock
on the Preferred Stock will generally be treated as dividends to U.S. Holders,
taxable as ordinary income to the extent of the Company's current and
accumulated earnings and profits as determined under U.S. federal income tax
principles. The amount of a distribution will be either the amount of cash
distributed or, in the case of additional shares of Preferred Stock, the fair
market value of the Preferred Stock distributed on the date of the distribution.
Accordingly, with respect to a distribution of additional shares of Preferred
Stock that is treated as a dividend, the fair market value of the distributed
shares would be taxable currently as ordinary income to a U.S. Holder even
though the U.S. Holder has not received any cash with respect to such
distribution.
 
    However, management of the Company has determined that the Company does not
presently have any current or accumulated earnings and profits and is unlikely
to have current or accumulated earnings and profits in the foreseeable future.
The actual amount of the Company's earnings and profits at any future time will
of course depend upon the actions and financial performance of the Company.
 
    Therefore, assuming the Company will not have any current or accumulated
earnings and profits, a distribution on the Preferred Stock 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 U.S. 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 the U.S. Holder upon the sale or
other taxable disposition of the Preferred Stock. The amount of any such
distribution which exceeds the adjusted tax basis of the Preferred Stock in the
hands of the U.S. Holder will be treated as capital gain and will be either
long-term or short-term capital gain depending on the U.S. Holder's holding
period for the Preferred Stock. The initial tax basis of additional Preferred
Stock distributed to a U.S. Holder will equal the fair market value of such
additional Preferred Stock at the time of distribution. Accordingly, in the case
of distributions of additional Preferred Stock on the Preferred Stock, any basis
reduction or gain recognition will be offset from an overall standpoint by a
corresponding amount of tax basis in the additional Preferred Stock distributed
to the U.S. Holder.
 
    REDEMPTION PREMIUM.  The Preferred Stock provides for both a mandatory and
an optional right of redemption by the Company. As the redemption price of the
Preferred Stock is expected to exceed its issue price (by more than a de minimis
amount), the excess, referred to as the "redemption premium," may be taxable as
a constructive distribution of additional Preferred Stock to the U.S. Holder on
the Preferred Stock over a certain period under a constant interest rate method
similar to that applicable to recognizing OID on the Exchange Debentures. See
the discussion of "--Original Issue Discount" under "Ownership and Disposition
of the Exchange Debentures." To the extent the Company has current or
accumulated earnings and profits for a taxable year so that the constructive
distribution attributable to such year is treated as a dividend, the amount of
the constructive distribution will generally be taxable currently as ordinary
income even though the U.S. Holder does not receive any actual distribution and
will increase the U.S. Holder's adjusted tax basis in the Preferred Stock. See
the above discussion of "--Distributions on the Preferred Stock."
 
    Determined with reference to the OID Regulations, the issue price of the
Preferred Stock is equal to the first price to the public (excluding bond
houses, brokers, or similar persons or organizations acting in the capacity of
underwriters, placement agents, or wholesalers) at which a substantial amount of
the Preferred Stock is sold for money, even if part of the issue is subsequently
sold at a different price. Similarly, the difference between redemption price
and issue price is considered de minimis if such amount is less than the product
of (i) one-quarter of one percent of the redemption price and (ii) the number of
complete years to maturity.
 
                                      179
<PAGE>
    To the extent the Company lacks 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. Moreover, there should be no net effect on the holder's adjusted
tax basis of the Preferred Stock as a result of the constructive distribution if
the Company has no current or accumulated earnings and profits.
 
    For purposes of determining the amount of the redemption premium, redemption
of the Preferred Stock will be deemed to occur at the mandatory redemption price
unless, based on all of the facts and circumstances, the optional redemption is
more likely than not to occur. Under a Regulatory "safe harbor" rule, the
Company's optional right to redeem the Preferred Stock will not be treated as
more likely than not to occur if (i) the Company and the U.S. Holder are not
related, (ii) there are no plans, arrangements or agreements that effectively
require or are intended to compel the Company to exercise the optional right to
redeem the Preferred Stock (disregarding, for this purpose, a separate mandatory
redemption) and (iii) exercise of the right to redeem will not reduce the yield
of the Preferred Stock. Based on the Treasury Regulations, the Company intends
to take the position that the existence of the Company's optional redemption
right does not result in a constructive distribution to the U.S. Holders, but
that the mandatory redemption obligation of the Company will control the timing
and the amount of the income a U.S. Holder of Preferred Stock will be required
to include in gross income as redemption premium.
 
    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 the Preferred Stock,
there were no intention for dividends to be paid currently, the IRS could treat
the payment of such dividends on redemption as disguised additional redemption
premium subject to the constant yield rules discussed above. However, the
Company intends to pay all dividends currently on the Preferred Stock, either in
cash or, on or prior to January 15, 2003, in additional shares of Preferred
Stock. 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, the Company intends to take the position that
the terms of the mandatory redemption should not include any accrued and unpaid
dividends in the stated redemption price nor should any such accrued and unpaid
dividends be treated as a constructive distribution to the U.S. Holders prior to
actually being paid.
 
    Finally, in the event that additional Preferred Stock is distributed on the
Preferred Stock issued in this Offering and such additional Preferred Stock has
a fair market value at the time of distribution that is less than its redemption
price, the additional Preferred Stock will have a redemption premium that may be
taxable as a constructive distribution of additional stock to a U.S. Holder
(treated as a dividend to the extent of the Company's current and accumulated
earnings and profits) under the constant yield method over a period of time
commencing with the issuance of such additional Preferred Stock and ending with
the date on which the mandatory redemption is to occur. Such redemption premium
on the additional shares of Preferred Stock may differ from that attributable to
the Preferred Stock issued in this Offering. Therefore, any such additional
shares of Preferred Stock distributed may not be fungible with the shares issued
in this Offering.
 
    DIVIDENDS-RECEIVED DEDUCTION.  Subject to certain exceptions and
restrictions, corporate U.S. Holders generally will be entitled to a
dividends-received deduction equal to 70 percent of the amount of any
distribution on the Preferred Stock (whether payable in cash or additional
Preferred Stock) that is treated as a dividend. Distributions on the Preferred
Stock will not be eligible for the dividends-received deduction unless and until
the Company has current or accumulated earnings and profits at the time of the
distribution (i.e., the distribution is treated as a dividend).
 
    In the event a distribution on the Preferred Stock is treated as a dividend,
application of the dividends-received deduction to the distribution nonetheless
may be restricted or may result in other U.S. federal tax consequences to the
corporate U.S. Holder. First, the dividends-received deduction is reduced or
eliminated for a corporate U.S. Holder which has indebtedness "directly
attributable" to its investment in the Preferred Stock or fails to meet special
holding period requirements. Second, if a distribution equals
 
                                      180
<PAGE>
or exceeds five percent of a corporate U.S. Holder's adjusted tax basis in the
Preferred Stock, the distribution may constitute an "extraordinary dividend,"
requiring the corporate U.S. Holder to reduce its adjusted tax basis in the
Preferred Stock by the amount excluded from income as a result of the dividends-
received deduction. Finally, 70 percent of the amount excluded from income as a
result of the dividends-received deduction will be included in the computation
of "adjusted current earnings," potentially affecting a corporate U.S. Holder's
liability for alternative minimum tax.
 
    SALE OR OTHER DISPOSITION OF THE PREFERRED STOCK
 
    GENERAL.  A U.S. Holder will generally 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. A U.S. 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 or 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.
See the above discussion of "--Redemption Premium" and "--Distributions on the
Preferred Stock."
 
    The capital gain or loss will be either long-term or short-term capital gain
depending on the U.S. Holder's holding period for the Preferred Stock at the
time of the sale or other disposition of the Preferred Stock. In the case of a
noncorporate U.S. Holder (including an individual), any capital gain will be
taxable at a preferential rate if the U.S. Holder's holding period for the
Preferred Stock exceeds one year. The deductibility of capital losses is subject
to limitations. Prospective investors should consult their own tax advisors
regarding the taxation of capital gains and capital losses recognized upon a
sale or other disposition of the Preferred Stock.
 
    REDEMPTION OR EXCHANGE OF PREFERRED STOCK FOR EXCHANGE DEBENTURES
 
    GENERAL.  A redemption of the Preferred Stock for cash or an exchange of the
Preferred Stock for the Exchange Debentures will be treated, depending on the
facts and circumstances, as (i) a distribution on the Preferred Stock, or (ii) a
taxable exchange of the Preferred Stock. At the outset, any cash paid or
Exchange Debentures issued that are attributable to declared dividends will be
treated in the same manner as a distribution on the Preferred Stock. See the
above discussion of "--Distributions on the Preferred Stock."
 
    A redemption or exchange of the Preferred Stock will be treated as a taxable
exchange of the Preferred Stock if the redemption or exchange results in either
(i) a complete termination, or (ii) a "meaningful reduction" of the U.S.
Holder's stock interest in the Company. For these purposes, a U.S. Holder is
deemed to own any shares of Company stock that are owned, or deemed owned, by
certain related persons and entities, as well as any shares that the Holder, or
a related person or entity, has the right to acquire by exercise of option. If
the redemption or exchange of the Preferred Stock does not result in a complete
termination or meaningful reduction of the U.S. Holder's stock interest in the
Company, the transaction will be treated as a distribution on the Preferred
Stock. See the above discussion of "--Distributions on the Preferred Stock." The
amount of the distribution will be measured by the amount of cash or the "issue
price" of the Exchange Debentures received by the U.S. Holder in consideration
for the Preferred Stock. To the extent the distribution is treated as a
dividend, it will be taxable as ordinary income and may have dividends-received
deduction, extraordinary dividend and/or alternative minimum tax consequences to
a corporate U.S. Holder. See the above discussion in "--Distributions on the
Preferred Stock."
 
    If the redemption or exchange of the Preferred Stock results in a complete
termination or meaningful reduction of the U.S. Holder's stock interest in the
Company, the U.S. Holder will generally recognize capital gain or loss equal to
the difference between the amount realized by the U.S. Holder and the U.S.
Holder's adjusted tax basis in the Preferred Stock surrendered in the
transaction. The capital gain or
 
                                      181
<PAGE>
loss will be either long-term or short-term capital gain depending on the U.S.
Holder's holding period for the Preferred Stock at the time of the sale or other
disposition of the Preferred Stock.
 
    In the case of a noncorporate U.S. Holder (including an individual), any
capital gain will be taxable at a preferential rate if the U.S. Holder's holding
period for the Preferred Stock exceeds one year. The deductibility of capital
losses is subject to limitations.
 
    The amount realized by a U.S. Holder will be (i) the amount of cash received
in redemption of the Preferred Stock (other than cash received with respect to
declared dividends), and (ii) an amount equal to the "issue price" of the
Exchange Debentures issued in exchange for the Preferred Stock (other than
Exchange Debentures issued with respect to declared dividends). Determination of
the "issue price" of the Exchange Debentures issued in exchange for the
Preferred Stock will depend on (i) whether the Preferred Stock or the Exchange
Debentures are traded on an established securities market within the meaning of
the OID Regulations during the 60 day period ending 30 days after the exchange
date, or (ii) if they are not so traded, the yield on the Exchange Debentures,
as of the exchange date, equals or exceeds the AFR. See the discussion of
"--Original Issue Discount" under "--Ownership and Disposition of the Exchange
Debentures." 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 AFR.
 
OWNERSHIP AND DISPOSITION OF THE EXCHANGE DEBENTURES
 
    Depending upon a U.S. 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 the
dividends-received deduction that may be available to corporate U.S. Holders
(subject to the Company having earnings and profits) and because, as discussed
below, the Exchange Debentures may be issued with OID.
 
    The tax consequences of holding the Exchange Debentures will generally turn
on whether the Exchange Debentures are issued with OID. Exchange Debentures
issued within five years after issuance of the Preferred Stock in this Offering
likely will be OID Debentures, i.e., Exchange Debentures treated as having been
issued with OID. Exchange Debentures issued more than five years after issuance
of the Preferred Stock will not be issued with OID unless, as discussed below,
their stated redemption price at maturity exceeds their issue price.
 
    ORIGINAL ISSUE DISCOUNT
 
    GENERAL.  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).
 
    Determination of the "issue price" of the Exchange Debentures issued in
exchange for the Preferred Stock will depend on whether, as of the exchange date
(i) the Preferred Stock or the Exchange Debentures are traded on an established
securities market within the meaning of the OID Regulations, or (ii) if they are
not so traded, the yield on the Exchange Debentures equals or exceeds the AFR.
If either the Exchange Debentures or the Preferred Stock are traded on an
established securities market during the 60 day period ending 30 days after the
exchange date, the issue price of the Exchange Debentures will equal the fair
market value of the traded property. If neither the Preferred Stock nor the
Exchange Debentures
 
                                      182
<PAGE>
are traded on an established securities market, the issue price of the Exchange
Debentures will be the stated principal amount of the Exchange debentures if the
yield on the Exchange Debentures is equal to or greater that the AFR in effect
at the time the Exchange Debentures are issued. If the yield on the Exchange
Debentures is less than the AFR, their issue price will be equal to the present
value as of the issue date of all payments to be made on the Exchange
Debentures, discounted at the AFR. 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 AFR.
 
    PAYMENT OF INTEREST BY ISSUANCE OF ADDITIONAL EXCHANGE DEBENTURES.
 
    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. Accordingly, none of the stated interest will be treated as
qualified stated interest unless under special rules for interest holidays the
amount of OID is treated as de minimis. Any additional Exchange Debentures
issued in lieu of cash will not be treated as debt instruments separate from the
Exchange Debentures upon which they were issued, but instead will be aggregated
with such Exchange Debentures for OID purposes.
 
    The OID Regulations provide that in the case of a debt instrument which
provides the issuer with an unconditional option or options exercisable during
the term of the debt instrument which, if exercised, require payments to be made
on the debt instrument under an alternate payment schedule, the yield and
maturity of such debt instrument for purposes of calculating OID will be
determined by assuming the issuer will exercise, or will 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 were not exercised. Accordingly,
for purposes of calculating OID, it will be assumed that the Company 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 the Company 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, U.S. Holders of Exchange Debentures
would include OID in income in advance of the receipt of cash, regardless of
such U.S. 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 the Company will exercise the option
because to do so will minimize the yield. If the Company 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, the Company
will not have the option to pay interest with additional Exchange Debentures. In
such event, any Exchange Debenture will be issued with OID only to the extent
its principal amount exceeds its issue price by more than a de minimis amount
because (i) all interest payments on any Exchange Debenture issued will be
qualified stated interest, and (ii) the stated redemption price at maturity of
any Exchange Debenture will be equal to its principal amount.
 
                                      183
<PAGE>
    REPORTING PAYMENTS OF INTEREST AND OID ON THE EXCHANGE DEBENTURES
 
    NON-OID EXCHANGE DEBENTURES.  U.S. Holders of Exchange Debentures that are
not issued with OID will generally report the stated interest under the Exchange
Debentures as ordinary income under their regular method of tax accounting.
 
    OID DEBENTURES.  U.S. Holders of OID Debentures must include OID in gross
income for U.S. federal income tax purposes on an annual basis under a constant
yield accrual method, regardless of their method of accounting. As a result,
U.S. Holders will include OID in income in advance of the receipt of cash
attributable to that income. However, U.S. Holders of OID Debentures generally
will not be required to include separately in income cash payments received on
the OID Debentures, even if denominated as interest, to the extent such payments
do not constitute qualified stated interest (as defined above). The Company will
report to U.S. Holders of OID Debentures, on a timely basis, the reportable
amount of OID and interest income based on its understanding of applicable law.
 
    The amount of OID includible in income by the initial U.S. 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 U.S. 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 (a) the product of
the OID Debenture's adjusted issue price at the beginning of such accrual period
and its yield to maturity (the discount rate which, when used in computing the
present value of all principal and interest payments to be made under the OID
Debenture, produces an amount equal to the OID Debenture's issue price) over (b)
the amount 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 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 premium 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 the
option of the Company. For purposes of computing the yield of OID Debentures,
the Company 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 the Company's ability to redeem prior to stated maturity
will affect the yield to maturity of such instrument.
 
    In the event of a Change of Control, the Company 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. The Company does 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.
 
    ELECTION TO REPORT INTEREST AS OID.  U.S. 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 accrual method. 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
 
                                      184
<PAGE>
any amortizable bond premium or acquisition premium. The election must be made
for the taxable year in which the U.S. Holder acquired the Exchange Debenture,
and may not be revoked without the consent of the IRS. U.S. Holders should
consult with their own tax advisors about the election to report interest on the
Exchange Debentures as OID using the constant yield method.
 
    MARKET DISCOUNT ON RESALE OF EXCHANGE DEBENTURES
 
    If a U.S. 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 U.S. 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 U.S.
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 U.S. Holder elects to accrue on a constant yield method. A U.S.
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 day of the first taxable year to which the election applies and may not be
revoked without the consent of the IRS.
 
    ACQUISITION PREMIUM
 
    A U.S. 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 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 U.S. 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.
 
    AMORTIZABLE BOND PREMIUM
 
    If immediately after the time the Preferred Stock is exchanged for Exchange
Debentures or immediately after the time a subsequent U.S. Holder acquires
Exchange Debentures, the U.S. 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 "amortizable bond premium" and such U.S. Holder will not
be required to include any OID in income.
 
    A U.S. Holder generally may elect to amortize bond premium over the
remaining term of the Exchange Debenture on a constant yield method (subject to
special rules concerning early call provisions). The amount amortized in any
year will be treated as a reduction of the U.S. Holder's interest income from
the Exchange Debenture. Bond premium on an Exchange Debenture held by a U.S.
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 U.S.
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 IRS.
 
                                      185
<PAGE>
    REDEMPTION, SALE OR DISPOSITION OF EXCHANGE DEBENTURES
 
    Upon the redemption, sale, exchange or retirement of an Exchange Debenture,
a U.S. 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. The
adjusted tax basis of a U.S 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 U.S. Holder and reduced by any amortized premium and any cash
payments on the Exchange Debentures other than qualified stated interest.
 
    Such gain or loss will be capital gain or loss and will be long-term capital
gain of loss if at the time or redemption, sale, exchange or retirement the
Exchange Debenture has been held for more than one year. The deduction of
capital losses is subject to certain limitations. Prospective investors should
consult their own tax advisors regarding the taxation consequences of capital
gains and losses recognized upon a disposition of the Exchange Debentures.
 
    APPLICABLE HIGH YIELD DISCOUNT OBLIGATIONS
 
    If the yield-to-maturity on OID Debentures equals or exceeds the sum of (i)
the AFR in effect for the month in which the OID Debentures are issued, and (ii)
five percent, 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, the Company will not be allowed to take a deduction for
OID accrued on the OID Debentures for U.S. federal income tax purposes until
such time as the Company actually pays such OID in cash or in other property
(other than stock or debt of the Company or certain related parties).
 
    Moreover, if the yield-to-maturity on the OID Debenture exceeds the sum of
(i) the AFR, and (ii) six percent (such excess shall be referred to hereinafter
as the "Disqualified Yield"), the deduction for OID accrued on the OID
Debentures will be permanently disallowed (regardless of whether the Company
actually pays 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 the Company'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 U.S. Holders other
than certain exempt recipients (such as corporations). A 31 percent backup
withholding tax will apply to such payments if the U.S. 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 the U.S. Holder's U.S. federal income tax liability
provided the required information is timely furnished to the IRS.

    THE FOREGOING SUMMARY DOES NOT DISCUSS ALL ASPECTS OF U.S. FEDERAL INCOME

                              PLAN OF DISTRIBUTION
 
    There has previously been only a limited secondary market and no public
market for the Old Shares. The Company does not intend to apply for the listing
of the Shares 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. The Company has 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 any Placement Agent 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
Shares may experience difficulty in reselling Shares. 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, the Company's results of operations and the market for similar
securities. Depending on such factors, such securities may trade at a discount
from their offering price.
 
   
    BROKER-DEALERS WHO DID NOT ACQUIRE OLD 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 Commission set forth in no-action letters issued to third parties,
the Company believes that a holder (other than a person that is an affiliate of
the Company within the meaning of Rule 405 under the Securities Act or a
"broker" or "dealer" registered under the Exchange Act) who exchanges Old 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 Commission enunciated in EXXON
CAPITAL HOLDINGS CORPORATION (available May 13, 1988) or similar no-action
letters or any similar interpretive letters and must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with a secondary resale transaction, unless an exemption from
registration is otherwise available.
 
    As contemplated by the no-action letters mentioned above and the
Registration Rights Agreement, each holder accepting the Exchange Offer is
required to represent to the Company in the Letter of Transmittal that (i) the
New Shares are to be acquired by the holder in the ordinary course of business,
(ii) the holder is not engaging and does not intend to engage in the
distribution of the New Shares, and (iii) 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 the Company or an affiliate of the Company) 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. The Company has agreed to cause the Exchange Offer Registration
Statement, of which this Prospectus is a part, to remain continuously effective
for a period of 180 days, if required, from the Exchange Date, and to make this
Prospectus, as amended or supplemented, available to any such Broker-Dealer for
use in connection with resales. Any Broker-Dealer participating in
 
                                      188
<PAGE>
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. The Company will not receive any
proceeds from any sale of New Shares by a Broker-Dealer.

                    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, 1996 and 1997, and the related consolidated statements of
operations, stockholders' deficit and cash flows for each of the three years in
the period ended December 31, 1997. 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 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 financial position of Dobson
Communications Corporation and subsidiaries as of December 31, 1996 and 1997,
and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION:
 
    Dobson Communications Corporation ("DCC" or the "Company") was incorporated
as an Oklahoma corporation in February 1997, under an Agreement and Plan of
Reorganization effective February 28, 1997. Under this plan, 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
reorganization, DCC is the parent company of DOC.
 
    As part of the reorganization, the stock of certain subsidiaries of DOC was
distributed to DCC. DOC continues to be the holding company for the Company's
cellular, local exchange and wholly-owned fiber subsidiaries. See Note 15 for
discussion of the Company's reorganization subsequent to December 31, 1997.
 
CAPITAL RESOURCES AND GROWTH
 
    The Company's total indebtedness and debt service requirements will
substantially increase as a result of the transactions described in Notes 7 and
15 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 15, including financial covenants, the
Company will be unable to borrow under 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.
 
WIRELESS ENTITIES
 
    The Company is comprised of the cellular entities listed below, which
operate cellular telephone systems servicing areas in Oklahoma, Texas, Kansas,
Missouri, Maryland, Pennsylvania and Arizona. The

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
wireless 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.
 
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.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
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. 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. No
such losses have been identified by the Company.
 
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 ten to fifteen years. Amortization
expense of $413,486, $1,596,794 and $10,528,125 was recorded in 1995, 1996 and
1997, respectively.
 
    The ongoing value and remaining useful lives of intangible and other
long-term assets are subject to periodic evaluation and the Company currently
expects the carrying amounts to be fully recoverable. When events and
circumstances indicate that intangible and other long-term assets might be
impaired, an undiscounted cash flow methodology would be used to determine
whether an impairment loss would be recognized.
 
DEFERRED COSTS
 
    Deferred costs consist primarily of fees incurred to secure long-term debt,
start-up costs and organizational costs. Deferred start-up costs are amortized
on a straight-line basis over three years. Deferred financing costs are being
amortized on a straight-line basis over the term of the debt of eight years.
Amortization expense related to these costs of $403,690, $401,871 and $1,074,845
was recorded in 1995, 1996 and 1997, 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 in 1997. 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 $851,107 was
recorded in 1997.
 
ADVERTISING COSTS
 
    Advertising costs are expensed as incurred and are included as marketing and
selling expenses in the accompanying consolidated statements of operations.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
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.
 
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 $858,000 and $1,209,000
as of December 31, 1996 and 1997, 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
 
    Basic income (loss) per common share is computed by the weighted average
number of shares of common stock outstanding during the year. Primary loss per
common share for 1996 was determined on the assumption that shares of Class B
convertible preferred stock were common stock from the date of their issuance as
each share of Class B convertible preferred stock is entitled to participate in
common stock dividends on a basis equivalent to shares of common stock, in
addition to the stated preferred stock dividend. In 1997, the Company adopted
SFAS No. 128, "Earnings Per Share." As a result, the Company's reported net
income (loss) per common share for 1995 and 1996 were restated.
 
    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
45% of the Company's cellular roaming revenue was earned from three cellular
carriers during the year ended December 31, 1997, while 54% and 56% of the
Company's cellular roaming revenue was earned from two cellular carriers during
the years ended December 31, 1995 and 1996, respectively.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
    In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income," effective for fiscal years beginning after December 15,
1997. Management of the Company plans to adopt this accounting standard as of
January 1, 1998. SFAS No. 130 requires that all items required to be recognized
under accounting standards as components of comprehensive income (loss),
consisting of both net income (loss) and those items that bypass the statement
of operations and are reported as a separate component of stockholders' deficit,
be reported in a financial statement that is displayed with the same prominence
as other financial statements. The Company does not believe that its
comprehensive income (loss) through December 31, 1997, will differ materially
from net income (loss).
 
3. PROPERTY, PLANT AND EQUIPMENT:
 
    Property, plant and equipment are recorded at cost. Newly constructed
cellular systems are added to property, plant and equipment at cost which
includes contracted services, direct labor, materials overhead and capitalized
interest. For the years ended December 31, 1995, 1996 and 1997, interest
capitalized was not material. Existing property, plant and equipment purchased
through acquisitions is recorded at its fair value at the date of the purchase.
Repairs, minor replacements and maintenance are charged to operations as
incurred. The provisions for depreciation are provided using the straight-line
method based on the estimated useful lives of the various classes of depreciable
property.
 
    Listed below are the major classes of property, plant and equipment and
their estimated useful lives, in years, as of December 31, 1996 and 1997:

REVOLVING CREDIT FACILITY
 
    On February 28, 1997, the Company's bank credit agreement was amended and
restated to provide the Company with a $200 million revolving credit facility
maturing in 2005. Interest on borrowings under the new credit agreement accrues
at variable rates (weighted average rate of 8.43% at December 31, 1997). Initial
proceeds were used to refinance existing indebtedness, finance the
Maryland/Pennsylvania Acquisition described in Note 7 and for general corporate
purposes, including $7.5 million to pay a dividend to holders of its Class A
Common stock. In connection with the closing of the revolving credit facility,
the Company extinguished its then existing 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 old revolving 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 the old revolving credit
agreement. In connection with this amendment, the Company recorded 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.
 
    In April 1997, the Company entered into an interest rate hedge agreement to
hedge the Company's interest expense on its indebtedness under the revolving
credit facility. The agreement provides for a rate cap of 8% plus a factor,
based on the Company's leverage ratio (cap at December 31, 1997, was 10.5%),
terminating on the earlier of April 24, 2000, or the date an option to enter
into an interest rate swap transaction is exercised by the counterparty. Under
the swap agreement, the interest rate would be fixed at 6.13% plus the factor
used to determine the rate cap or a floating LIBOR rate, terminating on April
24, 2002. The Company accounts for this instrument as a hedge.
 
SENIOR NOTES
 
    On February 28, 1997, the Company issued $160 million principal amount of
11.75% senior notes maturing in 2007. The net proceeds were used to finance the
Maryland/Pennsylvania Acquisition described in Note 7 and to purchase securities
pledged to secure payment of the first four semi-annual interest payments on the
notes, which began on October 15, 1997. The pledged securities are reflected as
"restricted investments" in the Company's consolidated balance sheet. The senior
notes are redeemable at the option of the Company in whole or in part, on or
after April 15, 2002, initially at 105.875%. Prior to April 15, 2000, the
Company may redeem up to 35% of the principal amount of the senior notes at
111.750% with proceeds from sales of stock, provided that after any such
redemption at least $104 million remains outstanding.

5. RESTRICTED CASH AND INVESTMENTS:
 
    Restricted cash and investments consist of an interest pledge deposit of
approximately $26.8 million which includes an initial deposit of $38.4 million
(as discussed in Note 4), net of interest earned and payments issued to
bondholders. Amortization expense of $322,850 was recorded in 1997 for bond
premiums recorded with the purchase of the restricted investments. At December
31, 1997, the carrying value of these investments exceeded the market value by
approximately $404,000.
 
6. STOCKHOLDERS' DEFICIT:
 
    Effective February 28, 1997, the stockholders of DCC and Dobson Holdings
Corporation ("Dobson Holdings"), a new corporation, entered into an agreement
and plan of reorganization. Under the reorganization, Dobson Holdings acquired
all of the outstanding Class A common stock, Class C common stock and Class B
Preferred of DCC. In exchange, the holders of the Class A common stock and Class
B Preferred of DCC received equivalent shares of stock of Dobson Holdings. The
holders 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 wireless 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 4, the Company canceled
its then outstanding Class A and Class B common stock, thereby cancelling its
treasury 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.
 
    As part of this recapitalization of the Company, Dobson Telephone was
entitled to receive shares of Class C common stock in exchange for its shares of
Class B common stock. In 1997, the Company issued these shares of Class C Common
Stock to Dobson Telephone.
 
    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.
 
    Holders of Class B Preferred have the right to sell up to 50% and 100% of
their stock to the Company after March 19, 2001 and 2002, respectively, or upon
the occurrence of certain events, at the then fair market value. After March 19,
2003, the Company has the right to call all of the outstanding shares of Class B
Preferred at the then fair market value.
 
    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.
 
    Holders of Class C Preferred are entitled to 8% cumulative dividends as and
when declared by the board of directors of the Company and a liquidation
preference over the other classes of common stock and equity securities. The
Class C Preferred is not convertible and has no voting rights.
 
    The Company may redeem, by vote of the board of directors, the Class C
Preferred at any time and from time to time, in whole or in part. Upon the
earlier of the occurrence of certain events or February 28, 2002, the Company
must redeem all the outstanding shares of Class C Preferred at the liquidation
value thereof plus accrued dividends.

metropolitan area. This acquisition and the one completed on February 28, 1997,
are referred to together as the "Maryland/Pennsylvania Acquisition."
 
    On October 1, 1997, the Company purchased a 75% interest in the Gila River
Cellular General Partnership (the "Arizona 5 Partnership"), which owns the
cellular license for Arizona RSA 5, as well as the associated tangible operating
assets, and Gila River Telecommunications Subsidiary, Inc. ("GRTSI") purchased a
25% interest in the Arizona 5 Partnership. As part of this transaction, the
Company purchased the stock of Associated Telecommunications and Technologies,
Inc. ("ATTI"), which owned 49% of one of the partners of the Arizona 5
Partnership (with a 41.95% interest). Of the $14.2 million purchase price for
ATTI, $9.5 million was paid to a director and the chief executive officer and
the chairman of the board of the Company, who together owned two-thirds of the
ATTI stock. Contemporaneously, the Company received the following payments on
outstanding loans from affiliates: $1.9 million from the chairman of the board
of directors, president and chief executive officer of the Company, $446,000
from a director and $1.9 million from an affiliate. Upon completion of these
transactions, the Company paid a net purchase price of $39.8 million for its 75%
interest in the Arizona 5 Partnership. In addition, the Company financed
approximately $5.2 million of the $13.3 million purchase price paid by GRTSI for
its 25% interest in the Arizona 5 Partnership. The $5.2 million note receivable
bears interest at the Company's available rate under its revolving credit
facility. Principal and interest will be paid from 60% of partnership
distributions beginning after September 30, 1998. Any unpaid amounts of
principal and interest are due on December 31, 2013.
 
    The acquisition transactions were accounted for as purchases and,
accordingly, their results of operations have been included in the accompanying
consolidated statements of operations from the respective dates of acquisition.
The unaudited pro forma information set forth below includes all acquisitions
for the years ended 1997 and 1996, respectively, as if the purchases occurred at
the beginning of 1996. The unaudited pro forma information is presented for
informational purposes only and is not necessarily indicative of the results of
operations that actually would have been achieved had the acquisitions been
consummated at that time:

States Government at an annual interest rate of 6.25% (see Note 4). This
represented a non-cash financing activity, and accordingly, is not reflected in
the accompanying consolidated statement of cash flows. Interest payments are due
quarterly beginning no earlier than April 30, 1998. The obligations will be
amortized quarterly over an eight-year period beginning in 1999.
 
8. EMPLOYEE BENEFIT PLANS:
 
401(k) PLAN
 
    The Company maintains a 401(k) plan (the "Plan") in which substantially all
employees of the Company are eligible to participate. The Plan requires the
Company to match 100% of employees' contributions up to 4% of their salary.
Contributions to the Plan charged to the Company's operations were approximately
$105,000, $109,000 and $179,000 during the years ended December 31, 1995, 1996
and 1997, respectively.
 
STOCK OPTION PLAN
 
    The Company has adopted a stock option plan, the 1996 Stock Option Plan
("1996 Plan"). The Company accounts for this plan under APB Opinion 25, under
which no compensation cost is recognized in the accompanying consolidated
financial statements if the option price is equal to or greater than the fair
market value of the stock at the time the option is granted.
 
    Under the Company's 1996 Plan, the Board of Directors may grant both
incentive and non-incentive stock options for employees, officers and directors
to acquire Class B Common Stock. Since the 1996 Plan's adoption, stock options
have been issued at the market price on the date of grant with an expiration of
ten years from the grant date. Options granted to one employee during 1997
representing 42.9% of total options granted in 1997 vest as follows: options to
purchase 12% of such shares first become exercisable on each of the first five
anniversaries of the grant date; options to purchase an additional 8% of such
shares first become exercisable on the same dates if annual performance
objectives are achieved. The remaining options issued in 1997 and all of the
options issued in 1996 vest at a rate of 20% per year. The Company has reserved
30,166 shares of authorized but unissued Class B Common Stock for issuance under
the 1996 Plan.

13. LITIGATION SETTLEMENT:
 
    On February 16, 1994, a judgment was entered against Dobson Cellular
Systems, Inc. ("Dobson Cellular") in a lawsuit initiated by a competitor for
violation of the Federal Communications Act in connection with pricing of
various services in the Texas RSA 2 market area in the amount of $742,318, and
post-judgment interest at a rate of 3.74% from the date of the judgment until
the amount was to be paid in full.
 
    Management of the Texas Partnership agreed to reimburse Dobson Cellular for
any and all costs related to these actions. A provision of $150,000 was charged
to the Texas Partnership's operations in 1993, for anticipated costs of
appealing the judgment. During 1995, this case was settled at a total cost to
the Texas Partnership of approximately $430,000, net of insurance proceeds. A

15. SUBSEQUENT EVENTS:
 
PREFERRED STOCK
 
    In January 1998, the Company issued 175,000 shares of 12.25% senior
exchangeable preferred stock mandatorily redeemable in 2008 for $1,000 per
share. Holders of the preferred stock are entitled to cumulative dividends from
the date of issuance and a liquidation preference over the other classes of
capital stock. Additionally, the preferred stock is redeemable at the option of
the Company on or after January 15, 2003. Holders of the preferred stock have no
voting rights. The preferred stock is not registered under the Securities Act of
1933 and may not be offered or sold in the United States without registration or
absent an applicable exemption from registration requirements. The Company must
make an offer to exchange substantially identical shares registered under the
Securities Act of 1933 for the shares outstanding within six months of the
issuance, or the stated dividend rate will increase by .5%.
 
REORGANIZATION
 
    In conjunction with the issuance of the preferred stock discussed above, the
Company formed three new subsidiaries: Dobson Cellular Operating Company
("DCOC"), DOC Cellular Subsidiary Company ("DOC Cellular Subsidiary") and Dobson
Wireline Company ("DWC"). DCOC was created as the holding company for
subsidiaries formed to effect cellular acquisitions. DCOC has been designated an
unrestricted subsidiary under the senior note indenture which covers the senior
notes discussed in Note 4. DOC Cellular Subsidiary was created as the holding
company for the then existing cellular subsidiaries. DWC was created as the
holding company for the Company's wireline, fiber and resale operations. DWC was
designated an unrestricted subsidiary under the senior note indenture and the
certificate of designation establishing the preferred stock. On September 30,
1998, the Company adopted a plan to spin off DWC, as discussed below.
 
CREDIT FACILITY
 
    In March 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, including the Texas 16 assets and assets acquired in future wireless
acquisitions. The Company's subsidiary DOC also established a $250 million
senior secured credit facility (the "Amended Bank Facility") to replace the
existing revolving credit facility discussed in Note 4. The Amended Bank
Facility continues to be 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. The DCOC Credit Facility and the Amended Bank
Facility requires 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. The credit
facilities will be used primarily to refinance existing indebtedness, finance
capital expenditures, consummate acquisitions, finance interest payments on the
Company's 11.75% senior notes, and fund general corporate operations. The
facilities will terminate in 2006.
 
    In connection with the closing of the Amended Bank Facility, the Company
extinguished its then existing 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 in March 1998.
Such amount is included in deferred costs in the accompanying consolidated
balance sheets at December 31, 1997.

DISCONTINUED OPERATIONS
 
    On September 30, 1998, the Company's Board of Directors authorized the
distribution of the wireline segment to the holders of the Company's common
stock on a tax-free basis, subject to the receipt of a private letter ruling
from the Internal Revenue Service ("IRS") under Internal Revenue Code 355(e).
The request was filed with the IRS on October 6, 1998, and a ruling is expected
in the second quarter of 1999. The wireline segment, which consists of Logix and
its subsidiaries, operates as an integrated communications provider under the
LOGIX-SM- 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 of discontinued operations" on the consolidated balance sheets and

statements of operations for the nine months ended September 30, 1998 and 1997
and the condensed consolidated statements of cash flows for the nine months

    The condensed balance sheet data at December 31, 1997 was derived from
audited financial statements, but does not include all disclosures required by
generally accepted accounting principles. The financial statements presented
herein should be read in connection with the Company's December 31, 1997
consolidated financial statements included in the Company's Annual Report on
Form 10-K for the fiscal year ended December 31, 1997.
 
1. ORGANIZATION
 
    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 wireless 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 5),
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. DCOC was created as the holding company for subsidiaries formed to
effect certain wireless acquisitions. DCOC has been designated an unrestricted
subsidiary under the Senior Note Indenture which covers the Senior Notes
discussed in Note 4. DOC Cellular Subsidiary was created as the holding company
for the then existing wireless 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.

4. LONG-TERM DEBT (CONTINUED)
REVOLVING CREDIT FACILITIES
 
    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. As of September 30, 1998, $143 million was outstanding under the DCOC
Credit Facility. At the same time, the Company's subsidiary DOC established a
$250 million senior secured credit facility (the "DOC Bank Facility") to replace
its existing revolving credit facility established on February 28, 1997 and
discussed below. The DOC Bank 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 Bank Facility. As of September 30, 1998, $141
million was outstanding under the DOC Bank Facility. The DCOC Credit Facility
and the DOC Bank 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. Interest on borrowings under the new credit agreements accrue at
variable rates (weighted average rate of approximately 6.9% at September 30,
1998). Initial proceeds were used primarily to refinance existing indebtedness
and finance the 1998 acquisitions described above. The Company expects to use
the remaining availability to finance capital expenditures, consummate future
acquisitions and fund general corporate operations. The facilities will
terminate in 2006.
 
    In connection with the closing of the DOC Bank Facility, the Company
extinguished its then existing 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 condensed consolidated statement of operations, net of
tax, for the nine months ended September 30, 1998 as an extraordinary expense.
 
    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 revolving credit facilities. Subsequent to
September 30, 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.
 
    On February 28, 1997, the Company's bank credit agreement was amended and
restated to provide the Company with a $200 million revolving credit agreement
facility maturing in 2005 ("1997 Credit Facility"). Interest on borrowings under
the credit agreement accrued at a variable rate. Initial proceeds were used to
refinance existing indebtedness, finance the Maryland/Pennsylvania Acquisition
described in Note 2 and for general corporate purposes, including $7.5 million
to pay a dividend to holders of its Class A Common Stock. In connection with the
closing of the revolving credit facility, the Company extinguished its then
existing 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 old revolving credit facility. This loss has been reflected
as an extraordinary item, net of tax, in the Company's condensed consolidated
statement of operations for the nine months ended September 30, 1997.

4. LONG-TERM DEBT (CONTINUED)
SENIOR NOTES
 
    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
Maryland/Pennsylvania Acquisition described above and to purchase securities
pledged to secure payment of the first four semi-annual interest payments on the
notes, which began on October 15, 1997. The pledged securities are reflected as
restricted cash and investments in the Company's condensed consolidated balance
sheets. The DCC Senior Notes are redeemable at the option of the Company in
whole or in part, on or after April 15, 2002, initially at 105.875%. Prior to
April 15, 2000, the Company may redeem up to 35% of the principal amount of the
DCC Senior Notes at 111.750% with proceeds from sales of stock, provided that
after any such redemption at least $104 million remains outstanding.
 
SYGNET FINANCING
 
    On July 20, 1998, in connection with the pending Sygnet Acquisition, the
Company received commitments for a new $450 million credit facility to be
secured by the assets acquired in the Sygnet Acquisition. The Company also
obtained commitments for bridge financing, which expired subsequent to September
20, 1998.
 
5. PREFERRED STOCK
 
    In January 1998, the Company issued 175,000 shares of 12.25% Senior
Exchangeable Preferred Stock mandatorily redeemable in 2008 for $1,000 per
share. Holders of the preferred stock are entitled to cumulative quarterly
dividends from the date of issuance and a liquidation preference of $1,000 per
share with rights over the other classes of capital stock. In 1998, the Company
has issued cumulative quarterly dividends in the form of 10,513 additional
shares of preferred stock (having a liquidation preference of $10.5 milion)
which represented non-cash financing activity, and thus are not included in the
accompanying condensed consolidated statement of cash flows. On and before
January 15, 2003, the Company may pay dividends, at its option, in cash or in
additional shares having an aggregate liquidation preference equal to the amount
of such dividends. Additionally, the preferred stock is redeemable at the option
of the Company on or after January 15, 2003. Holders of the preferred stock have
no voting rights.
 
6. RESTRICTED CASH AND INVESTMENTS
 
    Restricted cash and investments consist of securities pledged to secure
payment of interest on the DCC Senior Notes through April 1999.
 
7. TAXES
 
    The income tax benefit amounts for the nine months ended September 30, 1997
and 1998 differ from amounts computed at the statutory rate due primarily to net
operating losses for which no benefit has been recognized.
 
8. EARNINGS PER COMMON SHARE
 
    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.

9. RECENT 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. The Company has not yet evaluated
the impact of adopting SFAS 133 and has not determined the timing or method of
adoption of SFAS 133.
 
10. COMMITMENTS
 
    Effective December 6, 1995 (amended December 20, 1995, June 24, 1997 and
September 30, 1998), the Company entered into an equipment supply agreement in
which the Company agreed to purchase approximately $65 million of cell site and
switching equipment between June 24, 1997 and November 23, 2001 to update the
cellular systems for newly acquired and existing MSAs and RSAs. Of this
commitment, approximately $34.6 million remained at September 30, 1998.
 
    The Company entered into an additional equipment supply agreement with a
second vendor on January 13, 1998. The Company agreed to purchase approximately
$81 million of cell site and switching equipment between January 13, 1998 and
January 12, 2002 to update the cellular systems for newly acquired and existing
MSAs and RSAs. Of this commitment, $67 million remained at September 30, 1998.

                         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
December 31, 1995 and 1996, and the combined results of their operations and
their cash flows for each of the three years in the period ended December 31,
1996, in conformity with generally accepted accounting principles.

             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

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
                               DECEMBER 31, 1996
 
2. ACQUISITIONS (CONTINUED)
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.

                               DECEMBER 31, 1996
 
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:

                                                                        ----------  ----------
</TABLE>
 
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).

    Rental expense amounted to approximately $251,100 in 1994, $336,500 in 1995,

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

6. BENEFIT PLANS (CONTINUED)
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, 1996, 1995 AND 1994
 
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.

</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 8.1% for the year ended December 31,
1996 and 7.5% for the years ended December 31, 1995 and 1994. Interest expense
incurred and paid, net of amounts capitalized for the years ended December 31,
1996, 1995 and 1994 was $50,098, $50,024 and $0, 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

To the Partners
Cellular 2000 (A Partnership)
 
    We have audited the accompanying balance sheet of Cellular 2000 (A
Partnership) as of December 31, 1996 and 1997 and the related statements of
income, changes in partners' equity and cash flows for the years then ended.
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 audit.
 
    We conducted our audit 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 audit provides 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 Cellular 2000 (A
Partnership) as of December 31, 1996 and 1997 and the results of its operations
and its cash flows for the years then ended in conformity with generally
accepted accounting principles.

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

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.

                           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.

</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.

                         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:
 
<TABLE>
<S>                                                               <C>
                                                                       15-20

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.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                   DECEMBER 31, 1997, MARCH 31, 1997 AND 1998
 
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.
 
NOTE 2--SUPPLEMENTAL DISCLOSURES OF CASH FLOW INFORMATION
 
    Cash and cash equivalents at March 31, 1997 and 1998 for the statement of

    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

    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.

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.

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

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
              FOR THE YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
 
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
consolidated accounts of Sygnet Wireless, Inc. and its wholly-owned subsidiary
Sygnet Communications, Inc. ("Sygnet") (hereinafter collectively referred to as
the "Company") thereafter. The Company owns and operates cellular telephone
systems serving one large cluster with an approximate population of 2.4 million
in Northeastern Ohio, Western Pennsylvania and Western New York.
 
    On August 19, 1996, the shareholders of Sygnet and Wilcom effected a
corporate restructuring whereby Wilcom was merged into Sygnet and shareholders
of Wilcom received 8.72 shares of Sygnet common stock for each share of Wilcom
common stock held as of August 31, 1996, the effective date of the merger. This
merger was a business combination between entities under common control whereby
the assets and liabilities so transferred were accounted for at historical cost
in a manner similar to that in pooling-of-interest accounting. Also, in
conjunction with this merger, the shareholders of Sygnet amended the articles of
incorporation to change Sygnet's name to Sygnet Wireless, Inc.
 
    Prior to the restructuring, Sygnet and Wilcom had been operating their
cellular business through three partnerships (Youngstown Cellular Telephone
Company ("YCTC")), Erie Cellular Telephone Company ("Erie"), and Wilcom
Cellular) and Sharon--Youngstown Cellular, Inc. ("Sharon"). As a result of the
restructuring and merger, Sharon was renamed Sygnet and is the wholly-owned
subsidiary and operating company of Sygnet Wireless, Inc. The existence of YCTC,
Erie, and Wilcom Cellular terminated on October 1, 1996 when all partnership
interests transferred to Sygnet.
 
2. RECENTLY ISSUED ACCOUNTING STANDARDS
 
    In June 1997, the FASB issued Statement No. 130, REPORTING COMPREHENSIVE
INCOME, which is required to be adopted effective January 1, 1998. This
Statement establishes standards for the reporting and display of comprehensive
income and its components in a full set of general purpose financial statements.
Reclassification of financial statements for earlier periods presented is
required. The impact of Statement No. 130 on the Company's financial statements
is not expected to be material.
 
    In June 1997, the FASB also issued Statement No. 131, DISCLOSURES ABOUT
SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION, which is required to be
adopted effective January 1, 1998. This Statement changes the way companies
report selected segment information in annual financial statements and also
requires those companies to report selected segment information in interim
financial reports to shareholders. The impact of Statement No. 131 on the
Company's financial statement disclosures is not expected to be material.
 
3. ACQUISITIONS
 
    On October 9, 1996, the Company acquired certain cellular licenses,
property, equipment, customer lists, current assets and current liabilities of
Horizon Cellular Telephone Company of Chautauqua L.P., Horizon Cellular
Telephone Company of Crawford L.P., and Horizon Cellular Telephone Company of
Indiana L.P. (hereinafter collectively referred to as "Horizon") for cash of
$252.9 million. The acquired systems provide cellular service to an estimated
population of 1.4 million in contiguous markets in Western Pennsylvania and
Western New York.

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.

4. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    INVENTORY
 
    Inventory consisting of merchandise purchased for resale is stated at the
lower of cost or market determined by the first-in, first-out (FIFO) method.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are recorded at cost and are depreciated over their
estimated useful lives calculated under the straight-line or double-declining
balance methods.
 
    INTANGIBLE ASSETS
 
    The FCC issues licenses that enable cellular carriers to provide cellular
service in specific geographic areas. The FCC grants licenses for a term of up
to 10 years and generally grants renewals if the licensee has complied with its
obligations under the Communications Act of 1934. In 1993, the FCC adopted
specific standards to apply to cellular renewals, concluding it will award a
renewal to a cellular licensee that meets certain standards of past performance.
Historically, the FCC has granted license renewals routinely. The Company
believes that it has met, and will continue to meet all requirements necessary
to secure renewal of its cellular licenses.
 
    The Company has acquired cellular licenses and customer lists through its
acquisition of interests in various cellular systems. The cost of licenses and
customer lists acquired was $231,003,426 in 1996. The Company uses a 40 year
useful life to amortize its licenses under the straight-line method. Purchased
cellular and paging customer lists are being amortized over 5 years under the
straight-line method. The components of intangible assets at December 31 are
summarized below:

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

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

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

6. LONG-TERM DEBT
 
    On September 19, 1996, the Company issued $110,000,000 11 1/2% unsecured
Senior Notes due October 1, 2006 (the Notes). The Notes pay interest
semiannually on April 1 and October 1 of each year commencing April 1, 1997. The
Notes are redeemable at the option of the Company at redemption prices
(expressed as a percentage of principal amount) ranging from 105.75% in 2001 to
100.00% in 2005 and thereafter. Among other things, the Notes contain certain
covenants which limit additional indebtedness, payment of dividends, sale of
assets or stock, changes in control and transactions with related parties. The
proceeds from the Notes were used to repay amounts borrowed under a $75 million
bank credit agreement and to finance the acquisition of Horizon described in
Note 3.
 
    On October 9, 1996, Sygnet entered into a new financing agreement (the Bank
Credit Facility) with a commercial bank group. The Bank Credit Facility is a
senior secured reducing revolver that provides Sygnet the ability to borrow up
to $300.0 million through June 30, 1999. Mandatory reductions in the revolver
occur quarterly thereafter through June 30, 2005, when the Bank Credit Facility
terminates. The Bank Credit Facility is secured by certain assets and the stock
of Sygnet. The Bank Credit Facility provides for various borrowing rate options
based on either a fixed spread over the London Interbank Offered Rate (LIBOR) or
the prime rate. Interest payments are made quarterly. As of December 31, 1997,
$195.5 million was outstanding under the Bank Credit Facility.
 
    Among other things, the Bank Credit Facility contains financial covenants
which require the maintenance of debt service ratios and the hedging of interest
rate risk and limit distributions to shareholders and sales of assets. In
connection with these covenants, the Company has a three year interest rate swap
with a total underlying notional amount of $80 million. The swap agreements
converted the interest rate on $80 million notional amount of the credit
facility from a variable rate based upon a three month LIBOR (5.81% at December
31, 1997) to fixed rates ranging from 5.79% to 6.03%. Amounts paid or received
under these agreements are recognized as adjustments to interest expense.
 
    There are no future minimum payments based upon the borrowing levels at
December 31, 1997 for the next five years.
 
    Interest paid was $2,202,345, 4,691,776 and $30,076,031 in 1995, 1996 and
1997 respectively.
 
7. 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 approximately $460,800, $906,042 and $2,077,644 in 1995,
1996 and 1997, respectively.
 
8. RETIREMENT PLAN
 
    The Company sponsors a 401(k) retirement and profit sharing plan which
covers substantially all its employees. Eligible employees can contribute from
1% to 15% of their compensation. The Company, at its discretion, may match a
portion of the employee's contribution. The Company may also, at its discretion,
make additional profit sharing contributions to the plan. Total pension expense
was $114,000, $181,000 and $293,000 in 1995, 1996 and 1997, respectively.
 
9. REDEEMABLE PREFERRED STOCK AND WARRANTS
 
    On April 3, 1997, 100,000 shares of Series A Senior Cumulative Nonvoting
Preferred Stock (Preferred Stock) were redeemed by the Company at a cost of
$10,000,000 which was funded by the Bank Credit Facility. On June 20, 1997, the
remaining 118,394.51 shares of Preferred Stock were redeemed by the Company at a
cost of $11,839,451. This redemption was funded by the Common Stock Sale
described in Note 10.
 
    The Preferred Stock had a redemption value of $100 per share and was
recorded at fair value on the date of issuance less issuance costs. Dividends
were cumulative from the date of issuance, accrued quarterly in arrears and were
payable in shares of Preferred Stock. The dividend rates increased annually from
15% in 1997 to 21% in 2000 and thereafter. As of December 31, 1996, the Company
accrued stock dividends in the amount of $690,411 (which represented 6,904
shares). The Preferred Stock included the potential issuance of warrants to
purchase shares of the Company's Class A Common Stock. For financial reporting
purposes, the estimated fair value of the warrants was included with the
Preferred Stock in the accompanying balance sheet and the excess of the
redemption value of the Preferred Stock over the carrying value was accreted by
periodic charges to additional paid-in capital over the life of the issue. No
warrants were issued.
 
    The Company has authorized 5 million shares of Nonvoting Preferred Stock,
par value $.01 per share, of which 500,000 are designated as Series A Senior
Cumulative Nonvoting Preferred Stock.

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

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

12. STOCK OPTION PLAN (CONTINUED)
    For pro forma calculations the fair value of each option is estimated on the
date of grant using the Minimum Value option-pricing model with the following
weighted-average assumptions used for grants in both 1996 and 1997: risk-free
interest rates ranging from 5.9% to 6.9% and average expected lives ranging from
5.25 to 7.5 years for issued options.
 
    A summary of the status of the company's stock option plan as of December
31, 1996 and 1997 and changes during the years then ended is presented below:

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

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                                  (UNAUDITED)
 
4. REDEEMABLE PREFERRED STOCK AND WARRANTS (CONTINUED)
the Company at a cost of $11,839,451. This redemption was funded by the Common
Stock Sale described in Note 5.
 
    The Preferred Stock had a redemption value of $100 per share and was
recorded at fair value on the date of issuance less issuance costs. Dividends
were cumulative from the date of issuance, accrued quarterly in arrears and were
payable in shares of Preferred Stock. The dividend rates increased annually from
15% in 1997 to 21% in 2000 and thereafter. The Preferred Stock included the
potential issuance of warrants to purchase shares of the Company's Class A
Common Stock. For financial reporting purposes, the estimated fair value of the
warrants was included with the Preferred Stock in the accompanying balance sheet
and the excess of the redemption value of the Preferred Stock over the carrying
value was accreted by periodic charges to additional paid-in capital over the
life of the issue. No warrants were issued.
 
    The Company has authorized 5 million shares of Nonvoting Preferred Stock,
par value $.01 per share, of which 500,000 are designated as Series A Senior
Cumulative Nonvoting Preferred Stock.
 
5. SHAREHOLDERS EQUITY
 
    On June 20, 1997, the Company issued and sold 3,000,000 shares of Class A
Common Stock, $.01 par value, to Boston Ventures Limited Partnership V ("Boston
Ventures") at a price of $15 per share ("Common Stock Sale"). The proceeds of
$43.9 million, net of issuance fees, were used to redeem the remaining
outstanding Preferred Stock as described in Note 4, and to reduce amounts
outstanding under the Bank Credit Facility. As a condition of the Common Stock
Sale, Boston Ventures has two representatives on the Company's eleven member
board of directors.
 
    In August 1997, Boston Ventures purchased 1,000,000 shares of Class B Common
Stock from shareholders pursuant to a tender offer which, upon purchase, became
Class A Common Stock.
 
6. COMMITMENTS AND CONTINGENCIES
 
    In accordance with the Merger (see Note 2), the Company may be liable to pay
severance benefits and incentive compensation for an approximate amount of $1.9
million to certain employees if the Merger occurs and certain other conditions
are met before December 31, 1998.
 
    On June 8, 1998, the Company entered into an agreement with Pinellas
Communications to purchase the license to operate a cellular telephone system in
the Rural Service Area PA-2. The purchase price is $6.0 million and the
transaction is expected to close in the fourth quarter of 1998.

                                    PART II
                     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) 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
 
                                      II-8
<PAGE>
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.

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
67,148 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
                                          A Professional Corporation

<PAGE>
                                       
                       DOBSON COMMUNICATIONS CORPORATION 
                             1996 STOCK OPTION PLAN      

1.   PURPOSE.  The purpose of the Dobson Communications Corporation 1996 
     Stock Option Plan (the "Plan") is to encourage key employees of Dobson 
     Communications Corporation (the "Company") and of any present or future 
     parent or subsidiary of the Company (collectively, "Related 
     Corporations"), by providing opportunities to participate in the 
     ownership of the Company and its future growth through (a) the grant of 
     options which qualify as "incentive stock option" ("ISO") under Section 
     422(b) of the Internal Revenue Code of 1986, as amended (the "Code"); 
     and (b) the grant of options which do not qualify as ISOs 
     ("Non-Qualified Options").  Both ISOs and Non-Qualified Options are 
     referred to hereafter individually as an "Option" and collectively as 
     "Options." As used herein, the terms "parent" and "subsidiary" mean 
     "parent corporation" and "subsidiary corporation," respectively, as 
     those terms are defined in Section 424 of the Code.

2.   ADMINISTRATION OF THE PLAN    

     A.  BOARD OR COMMITTEE ADMINISTRATION.  The Plan shall be administered 
         by the Board of Directors of the Company (the "Board") or by a 
         committee appointed by the Board (the "Committee").  Hereinafter, 
         all references in this Plan to the "Committee" shall mean the Board 
         if no Committee has been appointed.  Subject to ratification of the 
         grant or authorization of each Option by the Board (if so required 
         by applicable state law), and subject to the terms of the Plan, the 
         Committee shall have the authority to (i) determine to whom (from 
         among the class of employees eligible under paragraph 3 to receive 
         ISOs) ISOs shall be granted, and to whom (from among the class of 
         individuals and entities eligible under paragraph 3 to receive 
         Non-Qualified Options) Non-Qualified Options shall be granted; (ii) 
         determine the time or times at which Options shall be granted; (iii) 
         determine the purchase price of shares subject to each Option, which 
         prices shall not be less than the minimum price specified in 
         paragraph 6; (iv) determine whether each Option granted shall be an 
         ISO or a Non-Qualified Option; (v) determine (subject to paragraph 
         7) the time or times when each Option shall become exercisable and 
         the duration of the exercise period; (vi) determine whether 
         restrictions such as repurchase options are to be imposed on shares 
         subject to Options and the nature of such restrictions, if any, and 
         (vii) interpret the Plan and prescribe and rescind rules and 
         regulations relating to it.  If the Committee determines to issue 
         Non-Qualified Option, it shall take 

<PAGE>

         whatever actions it deems necessary, under Section 422 of the Code 
         and the regulations promulgated thereunder, to ensure that such 
         Option is not treated as an ISO.  The interpretation and 
         construction by the Committee of any provisions of the Plan or of 
         any Option granted under it shall be final unless otherwise 
         determined by the Board.  The Committee may from time to time adopt 
         such rules and regulations for carrying out the Plan as it may deem 
         advisable. No member of the Board or the Committee shall be liable 
         for any action or determination made in good faith with respect to 
         the Plan or any Option granted under it.

     B.  COMMITTEE ACTIONS.  The Committee may select one of its members as 
         its chairman, and shall hold meetings at such time and places as it 
         may determine.  A majority of the Committee shall constitute a 
         quorum and acts of a majority of the members of the Committee at a 
         meeting at which a quorum is present, or acts reduced to or approved 
         in writing by all the members of the Committee, shall be the valid 
         acts of the Committee.  From time to time the Board may increase the 
         size of the Committee and appoint additional members thereof, remove 
         members (with or without cause) and appoint new members in 
         substitution therefor, fill vacancies however caused, or remove all 
         members of the Committee and thereafter directly administer the Plan.

3.   ELIGIBLE EMPLOYEES.  Options may be granted only to employees and 
     Directors of the Company or any Related Corporation.  The Committee may 
     take into consideration a recipient's individual circumstances in 
     determining whether to grant an Option.  The granting of any Option to 
     any individual shall neither entitle that individual to, nor disqualify 
     him from, participating in any other grant of Options.

4.   STOCK.  The stock subject to Options shall be authorized but unissued 
     shares of Class B Non-Voting Common Stock of the Company, par value 
     $1.00 per share (the "common Stock").  The aggregate number of shares 
     which may be issued pursuant to the Plan is 30,166, subject to 
     adjustment as provided in paragraph 13.  If any Option granted under the 
     Plan shall expire or terminate for any reason without having been 
     exercised in full or shall cease for any reason to be exercisable in 
     whole or in part, the unpurchased shares subject to such Option shall 
     again be available for grants of Options under the Plan.

5.   GRANTING OF OPTIONS.  Options may be granted under the Plan at any time 
     after June 1, 1996, and prior to June 1, 2006.  The date of grant of an 
     Option under the Plan will be the date specified by the Committee at the 
     time it grants the 

<PAGE>

     Option; provided, however, that such date shall not be prior to the date 
     on which the Committee acts to approve the grant.

6.   MINIMUM OPTION PRICE: ISO LIMITATIONS.

     A.  PRICE FOR NON-QUALIFIED OPTIONS.  The exercise price per share 
         specified in the agreement relating to each Non-Qualified Option 
         granted under the Plan shall in no event be less than the minimum 
         legal consideration required therefore under the laws of Oklahoma or 
         the laws of any jurisdiction in which the Company or its successors 
         in interest may be organized.

     B.  PRICE FOR ISOS.  The exercise price per share specified in the 
         agreement relating to each ISO granted under the Plan shall not be 
         less than the fair market value per share of Common Stock on the 
         date of such grant.  In the case of an ISO to be granted to an 
         employee owning stock possessing more than 10 percent (10%) of the 
         total combined voting power of all classes of stock of the Company 
         or any Related Corporation, the price per share specified in the 
         agreement relating to such ISO shall not be less than one hundred 
         ten percent (110%) of the fair market value per share of Common 
         Stock on the date of grant.  For purposes of determining stock 
         ownership under this paragraph, the rules of Section 424(d) of the 
         Code shall apply.

     C.  $100,000 ANNUAL LIMITATION ON ISO VESTING.  Each eligible employee 
         may be granted Options treated as ISOs only to the extent that, in 
         the aggregate under this Plan and all incentive stock option plans 
         of the Company and any Related Corporation, ISOs do not become 
         exercisable for the first time by such employee during any calendar 
         year with respect to stock having a fair market value (determined at 
         the time the ISOs were granted) in excess of $100,000.  The Company 
         intends to designate any Options granted in excess of such 
         limitation as Non-Qualified Options.

     D.  DETERMINATION OF FAIR MARKET VALUE.  If, at the time an Option is 
         granted under the Plan, the Company's Common Stock is publicly 
         traded, "fair market value" shall be determined as of the last 
         business day for which the prices or quotes discussed in this 
         sentence are available prior to the date such Option is granted and 
         shall mean (i) the average (on that date) of the high and low prices 
         of the Common Stock on the principal national securities exchange on 
         which the Common Stock is traded, if the Common Stock is then traded 
         on a national securities exchange; or (ii) the last reported sale 
         price (on that date) of the Common Stock on the 

<PAGE>

         NASDAQ National Market, if the Common Stock is not then traded on a 
         national securities exchange; or (iii) the closing bid price (or 
         average of bid prices) last quoted (on that date) by an established 
         quotation service for over-the-counter securities, if the Common 
         Stock is not reported on the NASDAQ National Market.  If the Common 
         Stock is not publicly traded at the time an Option is granted under 
         the Plan, "fair market value" shall mean the fair value of the 
         Common Stock as determined by the Committee after taking into 
         consideration all factors which it deems appropriate, including, 
         without limitation, recent sale and offer prices of the Common Stock 
         in private transactions negotiated at arm's length

7.   OPTION DURATION.  Subject to earlier termination as provided in 
     paragraphs 9 and 10 or in the agreement relating to such Option, each 
     Option shall expire on the date specified by the Committee, but not more 
     than (i) ten years from the date of grant in the case of Options 
     generally and (ii) five years from the date of grant in the case of ISOs 
     granted to an employee owning stock possessing more than ten percent 
     (10%) of the total combined voting power of all classes of stock of the 
     Company or any Related Corporation, as determined under paragraph 6(B).  
     Subject to earlier termination as provided in paragraphs 9 and 10, the 
     term of each ISO shall be the term set forth in the original instrument 
     granting such ISO, except with respect to any part of such ISO that is 
     converted into a Non-Qualified Option pursuant to paragraph 16.

8.   EXERCISE OF OPTION.  Subject to the provisions of paragraphs 9 through 
     12, each Option granted under the Plan shall be exercisable as follows:

     A.  VESTING.  The Option shall either be fully exercisable on the date 
         of grant or shall become exercisable thereafter in such installments 
         as the Committee may specify.

     B.  FULL VESTING OF INSTALLMENTS.  Once an installment becomes 
         exercisable it shall remain exercisable until expiration or 
         termination of the Option, unless otherwise specified by the 
         Committee.

     C.  PARTIAL EXERCISE.  Each Option or installment may be exercised at 
         any time or from time to time, in whole or in part, for up to the 
         total number of shares with respect to which it is then exercisable.

     D.  ACCELERATION OF VESTING.  The Committee shall have the right to 
         accelerate the date that any installment of any Option becomes 
         exercisable; provided that the 

<PAGE>

         Committee shall not, without the consent of an optionee, accelerate 
         the permitted exercise date of any installment of any Option granted 
         to any employee as an ISO (and not previously converted into a 
         Non-Qualified Option pursuant to paragraph 16) if such acceleration 
         would violate the annual vesting limitation contained in Section 
         422(d) of the Code, as described in paragraph 6(c).

     E.  EARLY EXERCISE.  An Option may, but need not, include a provision 
         whereby the optionee may elect at any time while an employee or 
         Director to exercise all or any of the installments included in the 
         grant of an Option prior to full vesting.  Any unvested shares 
         received pursuant to such early exercise may be subject to a 
         repurchase right in favor of the Company or to any other restriction 
         the Committee determines to be appropriate.

9.   TERMINATION OF EMPLOYMENT.  Unless otherwise specified in the agreement 
     relating to such ISO, if an ISO optionee ceases to be employed by the 
     Company and all Related Corporations other than by reason of death or 
     disability as defined in paragraph 10, no further installments of his or 
     her ISOs shall become exercisable, and his or her ISOs shall terminate 
     on the earlier of (a) ninety (90) days after the date of termination of 
     his or her employment, or (b) their specified expiration dates, except 
     to the extent that such ISOs (or unexercised installments thereof) have 
     been converted into Non-Qualified Options pursuant to paragraph 16.  For 
     purposes of this paragraph 9, employment shall be considered as 
     continuing uninterrupted during any bona fide leave of absence (such as 
     those attributable to illness, military obligations or governmental 
     service) provided that the period of such leave does not exceed 90 days 
     or, if longer, any period during which such optionee's right to 
     reemployment is guaranteed by statute.  A bona fide leave of absence 
     with the written approval of the Committee shall not be considered an 
     interruption of employment under this paragraph 9, provided that such 
     written approval contractually obligates the Company or any Related 
     Corporation to continue the employment of the optionee after the 
     approved period of absence.  ISOs granted under the Plan shall not be 
     affected by any change of employment within or among the Company and 
     Related Corporations, so long as the optionee continues to be an 
     employee of the Company or any Related Corporation.  Nothing in the Plan 
     shall be deemed to give any grantee of any Option the right to be 
     retained in employment by the Company or any Related Corporation for any 
     period of time.

10.  DEATH; DISABILITY

<PAGE>

     A.  DEATH.  If an ISO optionee ceases to be employed by the Company and 
         all Related Corporations by reason of his or her death, any ISO 
         owned by such optionee may be exercised, to the extent otherwise 
         exercisable on the date of his death, by his estate, personal 
         representative or beneficiary who has acquired the ISO by will or by 
         the laws of descent and distribution, until the earlier of (i) the 
         specified expiration date of the ISO or (ii) twelve months from the 
         date of the optionee's death.

     B.  DISABILITY.  If an ISO optionee ceases to be employed by the Company 
         and all Related Corporations by reason of his or her disability, 
         such optionee shall have the right to exercise any ISO held by him 
         or her on the date of termination of employment, for the number of 
         shares for which he or she could have exercised it on that date, 
         until the earlier of the specified expiration date of the ISO or 
         twelve months from the date of the termination of the optionee's 
         employment.  For the purposes of the Plan, the term "disability" 
         shall mean "permanent and total disability" as defined in Section 
         22(e)(3) of the Code or any successor statute.

11.  ASSIGNABILITY.  No Option shall be assignable or transferable by the 
     grantee except by will, by the laws of descent and distribution or, in 
     the case of Non-Qualified Options only, pursuant to a valid domestic 
     relations order.  Except as set forth in the previous sentence, during 
     the lifetime of a grantee each Option shall be exercisable only by such 
     grantee.

12.  TERMS AND CONDITIONS OF OPTIONS.  Options shall be evidenced by 
     instruments (which need not be identical) in such forms as the Committee 
     may from time to time approve.  Such instruments shall conform to the 
     terms and conditions set forth in paragraphs 6 through 11 hereof and may 
     contain such other provisions as the Committee deems advisable which are 
     not inconsistent with the Plan, including restrictions applicable to 
     shares of Common Stock issuable upon exercise of Options.  The Committee 
     may specify that any Non-Qualified Option shall be subject to the 
     restrictions set forth herein with respect to ISOs, or to such other 
     termination and cancellation provisions as the Committee may determine.  
     The Committee may from time to time confer authority and responsibility 
     on one or more of its own members and/or one or more officers of the 
     Company to execute and deliver such instruments.  The proper officers of 
     the Company are authorized and directed to take any and all action 
     necessary or advisable from time to time to carry out the terms of such 
     instruments.

<PAGE>

13.  ADJUSTMENTS.  Upon the occurrence of any of the following events, an 
     optionee's rights with respect to Options granted to such optionee 
     hereunder shall be adjusted as hereinafter provided, unless otherwise 
     specifically provided in the written agreement between the optionee and 
     the Company relating to such Option:

     A.  STOCK DIVIDENDS AND STOCK SPLITS.  If the shares of common stock of 
         the Company shall be subdivided or combined into a greater or 
         smaller number or shares or if the Company shall issue any shares of 
         its common stock as a stock dividend on its outstanding Common 
         Stock, the number of shares of Common Stock deliverable upon the 
         exercise of Options shall be appropriately increased or decreased 
         proportionately, and appropriate adjustments shall be made in the 
         purchase price per share to reflect such subdivision, combination or 
         stock dividend.

     B.  RECAPITALIZATION OR REORGANIZATION.  In the event of a 
         recapitalization or reorganization of the Company (other than in 
         connection with a transaction described in subparagraph C below) 
         pursuant to which securities of the Company or of another 
         corporation are issued with respect to the outstanding shares of 
         Common Stock, an optionee upon exercising an Option shall be 
         entitled to receive for the purchase price paid upon such exercise 
         the securities he would have received if he had exercised his Option 
         prior to such recapitalization or reorganization.

     C.  CHANGE IN CONTROL EVENTS.  In the event any Change in Control Event 
         (as defined below) occurs, each Option then outstanding shall, 
         immediately prior to such Change in Control Event (except as set 
         forth in subparagraph E below), be nonforfeitable and exercisable in 
         full.  A Change in Control Event shall mean any of the following:

         1.  Any transaction in which shares of voting securities of the 
             Company are sold or transferred by the Company or shareholders 
             of the Company as a result of which those persons and entities 
             who own voting securities of the Company prior to such 
             transaction own less than fifty percent (50%) of the outstanding 
             voting securities of the Company after such transaction;

         2.  The merger or consolidation of the Company with or into another 
             entity as a result of which less than fifty percent (50%) of the 
             outstanding voting securities of the surviving or resulting 
             entity are owned by those persons and entities who own 

<PAGE>

             voting securities of the Company prior to such merger or 
             consolidation; or

         3.  The sale of all or substantially all of the Company's assets to 
             an entity of which less than fifty percent (50%) of the 
             outstanding voting securities of such entity are owned by those 
             persons and entities who own voting securities of the Company at 
             the time of such asset sale.

The existence of any Option shall not in any way prevent any Related 
Corporation from engaging in any of the transactions described in this 
subparagraph C, nor shall it confer any rights upon the holder of any such 
Option to participate in any such transaction, except those expressly 
conferred by the Plan and the agreement pursuant to which such Option shall 
have been granted. Nothing contained in this Plan shall prevent the 
assumption of an Option, or the substitution of a new option for an Option, 
by any corporation, or the parent or subsidiary of any corporation, that 
becomes the employer of an optionee by reason of a merger, consolidation or 
acquisition; provided, however, that with respect to an ISO, the following 
additional conditions are applicable:

         1.  the excess of the aggregate fair market value of the shares 
             subject to the Option immediately after the substitution or 
             assumption over the aggregate option price of such shares is not 
             more than the excess of the aggregate fair market value of the 
             shares subject to the Option immediately before such 
             substitution or assumption over the aggregate option price of 
             such shares; and

         2.  the new option or the assumption of the old Option does not give 
             the optionee additional benefits that the optionee did not have 
             under the old Option.

     D.  MODIFICATION OF ISOs.  Notwithstanding the foregoing, any 
         adjustments made pursuant to subparagraphs A, B, or C with respect 
         to ISOs shall be made only after the Committee, after consulting 
         with counsel for the Company, determines whether such adjustments 
         would constitute a "modification" of such ISOs (as that term is 
         defined in Section 424 of the Code) or would cause any adverse tax 
         consequences for the holders of such ISOs.  If the Committee 
         determines that such adjustments made with respect to ISOs would 
         constitute a modification of such ISOs or would cause adverse tax 
         consequences to the holders, it may refrain from making such 
         adjustments.

     E.  DISSOLUTION OR LIQUIDATION.  In the event of the proposed 
         dissolution or liquidation of the Company,

<PAGE>

         each Option will terminate immediately prior to the consummation of 
         such proposed action or at such other time and subject to such other 
         conditions as shall be determined by the Committee.

     F.  ISSUANCES OF SECURITIES.  Except as expressly provided herein, no 
         issuance by the Company of shares of stock of any class, or 
         securities convertible into shares of stock of any class, shall 
         affect, and no adjustment by reason thereof shall be made with 
         respect to, the number or price of shares subject to Options.  No 
         adjustments shall be made for dividends paid in cash or in property 
         other than securities of the Company.

     G.  FRACTIONAL SHARES.  No fractional shares shall be issued under the 
         Plan and the optionee shall receive from the Company cash in lieu of 
         such fractional shares.

     H.  ADJUSTMENTS.  Upon the happening of any of the events described in 
         subparagraphs A, B, or C above, the class and aggregate number of 
         shares set forth in paragraph 4 hereof that are subject to Options 
         which previously have been or subsequently may be granted under the 
         Plan shall also be appropriately adjusted to reflect the events 
         described in such subparagraphs.  The Committee or the Successor 
         Board shall determine the specific adjustments to be made under this 
         paragraph 13 and, subject to paragraph 2, its determination shall be 
         conclusive.

14.  MEANS OF EXERCISING OPTIONS.  An Option (or any part of installment 
     thereof) shall be exercised by giving written notice to the Company at 
     its principal office address, or to such transfer agent as the Company 
     shall designate.  Such notice shall identify the Option being exercised 
     and specify the number of shares as to which such Option is being 
     exercised, accompanied by (i) an instrument of accession providing that 
     the optionee agrees to be bound by the terms, rights and obligations 
     applicable to "Shareholders" under that certain Shareholders' Agreement 
     dated as of March 19, 1996, by and among the Company and its 
     stockholders signatory thereto, as amended from time to time, and (ii) 
     full payment of the purchase price therefor either (a) in United States 
     dollars in cash or by check, (b) at the discretion of the Committee, 
     through delivery of shares of Common Stock having a fair market value 
     equal as of the date of the exercise to the cash exercise price of the 
     Option including withholding of shares of Common Stock otherwise 
     deliverable upon exercise of an Option, but only to the extent such 
     exercise of an Option would not result in an accounting compensation 
     charge with respect to the shares used to pay the exercise price unless 
     otherwise determined 

<PAGE>

     by the Committee, (c) at the discretion of the Committee, by delivery of 
     the grantee'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 Code, (d) at the discretion 
     of the Committee and consistent with applicable law, through the 
     delivery of an assignment to the Company of a sufficient amount of the 
     proceeds from the sale of the Common Stock acquired upon exercise of the 
     Option and an authorization to the broker or selling agent to pay that 
     amount to the Company, which sale shall be at the participant's 
     direction at the time of exercise, or (e) at the discretion of the 
     Committee, by any combination of (a), (b), (c) and (d) above.  If the 
     Committee exercises its discretion to permit payment of the exercise 
     price of an ISO by means of the methods set forth in clauses (b), (c), 
     (d) or (e) of the preceding sentence, such discretion shall be exercised 
     in writing at the time of the grant of the ISO in questions.  The holder 
     of an Option shall not have the rights of a shareholder with respect to 
     the shares covered by such Option until the date of issuance of a stock 
     certificate to such holder for such shares.  Except as expressly 
     provided above in paragraph 13 with respect to changes in capitalization 
     and stock dividends, no adjustment shall be made for dividends or 
     similar rights for which the record date is before the date such stock 
     certificate is issued.

15.  TERM AND AMENDMENT OF PLAN.  This Plan was adopted by the Board on June 
     1, 1996, subject, with respect to the validation of ISOs granted under 
     the Plan, to approval of the Plan by the stockholders of the Company at 
     the next meeting of Stockholders or, in lieu thereof, by written 
     consent.  If the approval of stockholders is not obtained prior to June 
     1, 1997, any grants of ISOs under the Plan made prior to that date will 
     be rescinded.  The Plan shall expire at the end of the day on June 1, 
     2006 (except as to Options outstanding on that date).  Subject to the 
     provisions of paragraph 5 above, Options may be granted under the Plan 
     prior to the date of stockholder approval of the Plan.  The Board may 
     terminate or amend the Plan in any respect at any time, except that, 
     without the approval of the stockholders obtained within 12 months 
     before or after the Board adopts a resolution authorizing any of the 
     following actions: (a) the total number of shares that may be issued 
     under the Plan may not be increased (except by adjustment 
     pursuant to paragraph 13); (b) the benefits accruing to participants 
     under the Plan may not be materially increased; (c) the requirements as 
     to eligibility for grants of ISOs may not be modified; (d) the 
     provisions of paragraph 3 regarding eligibility for grants of ISOs may 
     not be modified; (e) the provisions of paragraph 6(B) regarding the 
     exercise price at which shares may be offered pursuant to ISOs may not 
     be modified (except by adjustment 

<PAGE>

     pursuant to paragraph 13); (f) the expiration date of the Plan may not 
     be extended; and (g) the Board may not take any action which would cause 
     the Plan to fail to comply with Rule 16b-3.  Except as otherwise 
     provided in this paragraph 15, in no event may action of the Board or 
     stockholders alter or impair the rights of a grantee, without such 
     grantee's consent, under any Option previously granted to such grantee.

16.  CONVERSION OF ISOs INTO NON-QUALIFIED OPTIONS.  The Committee, at the 
     written request or with the written consent of any optionee, may in its 
     discretion take such actions as may be necessary to convert such 
     optionee's ISOs (or any installments or portions of installments 
     thereof) that have not been exercised on the date of conversion into 
     Non-Qualified Options at any time prior to the expiration of such ISOs, 
     regardless of whether the optionee is an employee of the Company or a 
     Related Corporation at the time of such conversion.  Such actions may 
     include, but shall not be limited to, extending the exercise period or 
     reducing the exercise price of the appropriate installments of such 
     ISOs.  At the time of such conversion, the Committee (with the consent 
     of the optionee) may impose such conditions on the exercise of the 
     resulting Non-Qualified Options as the Committee in its discretion may 
     determine, provided that such conditions shall not be inconsistent with 
     this Plan.  Nothing in the Plan shall be deemed to give any optionee the 
     right to have such optionee's ISOs converted into Non-Qualified Options, 
     and no such conversion shall occur until and unless the Committee takes 
     appropriate action.

17.  CANCELLATION OF OPTIONS.  The Board may, in its sole discretion, in 
     cases involving a serious breach of conduct by an employee or former 
     employee, or activity of a former employee in competition with the 
     business of the Company or a Related Corporation, cancel any Option, 
     whether vested or not, in whole or in part.  Such cancellation shall be 
     effective as of the date specified by the Board.  Without limitation, 
     activities which shall constitute a serious breach of conduct include: 
     (i) the disclosure or misuse of confidential information or trade 
     secrets; (ii) activities in violation of the policies of the Company or 
     any Related Corporation, including without limitation, the Company's 
     insider trading policy; (iii) the violation or breach of any material 
     provision in any employment contract or agreement among the employee and 
     any Related Corporation; (iv) engaging in conduct relating to the 
     optionee's employment with the Company or any Related Corporation for 
     which either criminal or civil penalties may be sought; and (v) engaging 
     in activities which adversely affects or which are contrary or harmful 
     to the interest of the Company, any Related Corporation or its business 
     operations.  The determination of whether an employee or former employee 
     has engaged in a 

<PAGE>

     serious breach of conduct or activity in competition with the business 
     of a Related Corporation shall be determined by the Board in good faith 
     and in its sole discretion.

18.  APPLICATION OF FUNDS.  The proceeds received by the Company from the 
     sale of shares pursuant to Options granted under the Plan shall be used 
     for general corporate purposes.

19.  NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION.  By accepting an ISO 
     granted under the Plan, each optionee agrees to notify the Company in 
     writing immediately after he makes a Disqualifying Disposition (as 
     described in Sections 421, 422, and 424 of the Code and regulations 
     thereunder) of any stock acquired pursuant to the exercise of ISOs 
     granted under the Plan.  A Disqualifying Disposition is generally any 
     disposition occurring on or before the later of (a) the date two years 
     following the date the ISO was granted or (b) the date one year 
     following the date the ISO was exercised.

20.  WITHHOLDING OF ADDITIONAL INCOME TAXES.  Upon the exercise of a 
     Non-Qualified Option, the making of a Disqualifying Disposition (as 
     defined in paragraph 19), the vesting or transfer of restricted stock or 
     securities acquired on the exercise of an Option hereunder, or the 
     making of a distribution or their payment with respect to such stock or 
     securities, the Company may withhold taxes in respect of amounts that 
     constitute compensation includible in gross income.  The Committee in 
     its discretion may condition the exercise of an Option, the vesting or 
     transferability of restricted stock or securities acquired by exercising 
     an Option, on the grantee's making satisfactory arrangement for such 
     withholding.  Such arrangement may include payment by the grantee's 
     delivery of previously held shares of Common Stock or the withholding 
     from the shares of Common Stock otherwise deliverable upon exercise of 
     an Option shares having an aggregate fair market value equal to the 
     amount of such withholding taxes.

21.  GOVERNMENTAL REGULATION.  The Company's obligation to sell and deliver 
     shares of the Common Stock under this Plan is subject to the approval of 
     any governmental authority required in connection with the 
     authorization, issuance or sale of such shares.

     Government regulations may impose reporting or other obligations on the 
     Company with respect to the Plan.  For example, the Company may be 
     required to send tax information statements to employees and former 
     employees that exercise Options under the Plan, and the Company may be 
     required to file tax information returns reporting the income received 
     by grantees of Options in connection with the Plan.

22.  GOVERNING LAW.  The validity and construction of the Plan 

<PAGE>

     and the instruments evidencing Options shall be governed by the laws of 
     Oklahoma, or the laws of any jurisdiction in which the Company or its 
     successors in interest may be organized.

The undersigned hereby certify that they are all the Directors of Dobson 
Communications Corporation entitled to vote on the foregoing matters and 
hereby consent to the foregoing Stock Option Plan of 1996.

     1998-1 AMENDMENT TO THE DOBSON COMMUNICATIONS CORPORATION
                      1996 STOCK OPTION PLAN


          A.   Section 4 of the Dobson Communications Corporation 1996 Stock 
Option Plan (the "Plan") is hereby amended to read as follows:

     "4.  STOCK.  The stock subject to Options and which may be issued
     pursuant to the Plan shall be (i) 30,166 authorized but unissued
     shares of Class B Non-Voting Common Stock of the Company, par value
     $.001 per share (the 'Class B Stock'), and (ii) 30,166 authorized but
     unissued shares of Class C Non-Voting Common Stock, par value $.001
     per share (the 'Class C Stock') (the Class B Stock and the Class C
     Stock are sometimes together referred to herein as the 'Common
     Stock').  The number of such shares is subject to adjustment as
     provided in paragraph 13.  If any Option granted under the Plan shall
     expire or terminate for any reason without having been exercised in
     full or shall cease for any reason to be exercisable in whole or in
     part, the unpurchased shares subject to such Option shall again be
     available for grants of Options under the Plan."

          B.   Section 14 of the Dobson Communications Corporation 1996 Stock
     Option Plan (the "Plan") is hereby amended to read as follows:

     "14. MEANS OF EXERCISING OPTIONS.  An Option (or any part of
          installment thereof) shall be exercised by giving written notice
          to the Company at its principal office address, or to such
          transfer agent as the Company shall designate.  Such notice shall
          identify the Option being exercised and specify the number of
          shares as to which such Option is being exercised, accompanied by
          (i) an instrument of accession providing that the optionee agrees
          to be bound by the terms, rights and obligations applicable to
          'Shareholders' under that certain Shareholders' Agreement dated
          as of March 19, 1996, by and among the Company and its
          stockholders signatory thereto, as amended from time to time, and
          (ii) full payment of the purchase price therefor either (a) in
          United States dollars in cash or by check, (b) at the discretion
          of the Committee, through delivery of shares of Common Stock
          having a fair market value equal as of the date of the exercise
          to the cash exercise price of the Option including 


                                      
<PAGE>

          withholding of shares of Common Stock otherwise deliverable upon 
          exercise of an Option, but only to the extent such exercise of an 
          Option would not result in an accounting compensation charge with 
          respect to the shares used to pay the exercise price unless 
          otherwise determined by the Committee, (c) at the discretion of the 
          Committee, by delivery of the grantee'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 Code, (d) at the discretion of the Committee and consistent 
          with applicable law, through the delivery of an assignment to the 
          Company of a sufficient amount of the proceeds from the sale of the 
          Common Stock acquired upon exercise of the Option and an 
          authorization to the broker or selling agent to pay that amount to 
          the Company, which sale shall be at the participant's direction at 
          the time of exercise, or (e) at the discretion of the Committee, by 
          any combination of (a), (b), (c) and (d) above.  If the Committee 
          exercises its discretion to permit payment of the exercise price of 
          an ISO by means of the methods set forth in clauses (b), (c), (d) or 
          (e) of the preceding sentence, such discretion shall be exercised in 
          writing at the time of the grant of the ISO in questions.  The 
          holder of an Option shall not have the rights of a shareholder with 
          respect to the shares covered by such Option until the date of 
          issuance of a stock certificate to such holder for such shares.  
          Except as expressly provided above in paragraph 13 with respect to 
          changes in capitalization and stock dividends, no adjustment shall 
          be made for dividends or similar rights for which the record date is 
          before the date such stock certificate is issued."

          Except as otherwise provided in this 1998-1 Amendment to the Dobson 
Communications Corporation 1996 Stock Option Plan ("Amendment"), the Plan is 
hereby ratified and confirmed in all respects.  This Amendment shall be 
effective as of December 21, 1998.
