                            ------------------------
 
    Logix Communications Enterprises, Inc., an Oklahoma corporation (the
"Company" or "Logix"), hereby offers (the "Exchange Offer"), upon the terms and
subject to the conditions set forth in this Prospectus and the accompanying
Letter of Transmittal to exchange $1,000 principal amount of its 12 1/4% Senior
Notes Due 2008 (the "New Notes"), which have been registered under the
Securities Act of 1933, as amended (the "Securities Act"), pursuant to a
Registration Statement of which this Prospectus is a part, for each $1,000
principal amount of its outstanding 12 1/4% Senior Notes Due 2008 (the "Old
Notes"), of which an aggregate of $350,000,000 in principal amount was
outstanding as of September 10, 1998.
                            ------------------------
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
   SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
     PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
                REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
                            ------------------------
 
    Interest on the New Notes will be paid in cash at a rate of 12 1/4% per
annum on each June 15 and December 15, commencing December 15, 1998. The New
Notes may be redeemed at the option of the Company, in whole or in part, at any
time on or after June 15, 2003 at 106.125% of their principal amount, plus
accrued interest, declining ratably to 100% of their principal amount, plus
accrued interest, on or after June 15, 2006. In addition, at any time prior to
June 15, 2001, the Company may redeem up to 35% of the aggregate principal
amount of the New Notes with the net proceeds of one or more sales of capital
stock of the Company, at 112.250% of their principal amount, plus accrued
interest; provided that after any such redemption at least $227.5 million
aggregate principal amount of Notes remains outstanding. See "Description of the
Notes."
 
   
    This Prospectus, together with the Letter of Transmittal, is being sent to
all registered holders of Old Notes as of November 6, 1998. As of such date, a
nominee for The Depository Trust Company was the only registered holder of the
Old Notes.
    
 
    The Company will not receive any proceeds from this Exchange offer. No
dealer-manager is being used in connection with this Exchange Offer. See "Use of
Proceeds" and "Plan of Distribution."
 
    WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED NOT TO SEND US A
PROXY.
 
                            ------------------------
 
   
                THE DATE OF THIS PROSPECTUS IS NOVEMBER 9, 1998.
    
<PAGE>
                          CERTAIN TENDER OFFER MATTERS
 
    The New Notes will be obligations of the Company entitled to the benefits of
the Indenture (as defined herein). The New Notes will be unsubordinated
indebtedness of the Company, ranking pari passu in right of payment with the Old
Notes and all other unsubordinated indebtedness of the Company and senior in
right of payment to all subordinated indebtedness of the Company. The Old Notes
and the New Notes (together, the "Notes") will be effectively subordinated to
all existing and future liabilities (including trade payables) of the Company's
subsidiaries. After giving effect to the offering and sale of the Old Notes (the
"Offering") and the American Telco Acquisition (as defined herein) (together,
the "Transactions"), on June 30, 1998, the Company had, on a consolidated basis,
$378.0 million of indebtedness outstanding and the Company's subsidiaries had
$43.4 million of liabilities in addition to the Notes (including $28.0 million
of indebtedness, all of which is secured), all of which effectively would rank
senior to the Notes, and the Company had no indebtedness ranking junior to the
Notes. The form and terms of the New Notes are identical in all material
respects to the form and terms of the Old Notes except that the New Notes have
been registered under the Securities Act. Any Old Notes not tendered and
accepted in the Exchange Offer will remain outstanding and will be entitled to
all the rights and preferences and will be subject to the limitations applicable
thereto under the Indenture. Following consummation of the Exchange Offer, the
holders of the Old Notes will continue to be subject to the existing
restrictions upon transfer thereof and the Company will have no further
obligation to such holders to provide for the registration under the Securities
Act of the Old Notes held by them. Following the completion of the Exchange
Offer, none of the Notes will be entitled to the contingent increase in interest
rate provided pursuant to the Old Notes. The Exchange Offer is being made
pursuant to the terms of the registration rights agreement (the "Registration
Rights Agreement") entered into between the Company and Morgan Stanley & Co.
Incorporated, and NationsBanc Montgomery Securities LLC (the "Placement Agents")
pursuant to the terms of the Placement Agreement dated June 10, 1998 between the
Company and the Placement Agents. See "The Exchange Offer--Purpose and Effect of
the Exchange Offer."
 
    Based on interpretations by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes the New Notes issued pursuant to the Exchange
Offer in exchange for Old Notes may be offered for resale, resold and otherwise
transferred by any holder thereof (other than broker-dealers, as set forth
below, and any holder that is an "affiliate" of the Company within the meaning
of Rule 405 under the Securities Act) without compliance with the registration
and prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such holder's business and that
such holder has no arrangement or understanding with any person to participate
in the distribution of such New Notes. Any holder who tenders in the Exchange
Offer with the intention to participate, or for the purpose of participating, in
a distribution of the New Notes or who is an affiliate of the Company may not
rely upon such interpretations by the staff of the Commission and, in the
absence of an exemption therefrom, must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
secondary resale transaction. Holders of Old Notes wishing to accept the
Exchange Offer must represent to the Company in the Letter of Transmittal that
such conditions have been met.
 
    Each broker-dealer (other than an affiliate of the Company) that receives
New Notes for its own account pursuant to the Exchange Offer must acknowledge
that it will deliver a prospectus meeting the requirements of the Securities Act
in connection with any resale of such New Notes. The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act. This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of New
Notes received in exchange for Old Notes where such Old Notes were acquired by
such broker-dealer as a result of market-making activities or other trading
activities. The Company has agreed that, for a period of 180 days after the last
date Old Notes are accepted for exchange pursuant to the Exchange Offer (the
"Exchange Date"), it will make this Prospectus available to any broker-dealer
for use in connection with any such resale. See "Plan of Distribution." Any
broker-dealer who is an affiliate of the Company may not rely on such no-action
letters and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction.

                                  THE COMPANY
 
    Logix Communications Enterprises, Inc. seeks to be the leading provider of
integrated local, long distance, data and other telecommunications services to
small and medium-sized business customers throughout the Southwest United
States. Since 1936, the Company, through its predecessors and subsidiaries, has
provided incumbent local exchange carrier ("ILEC") services in Oklahoma. In
addition, Logix Wireline operates long-haul fiber optic facilities in Oklahoma,
Texas and Colorado, providing wholesale long-haul services. Logix recently began
offering switch-based services as an integrated communications provider (an
"ICP") in Oklahoma City and Tulsa under its LOGIX-TM- brand name and expects to
commence offering these services in Amarillo in late 1998.
 
    In order to accelerate the expansion of its ICP business, on June 15, 1998,
Logix acquired Houston-based American Telco for $131.5 million. American Telco
provides long distance and local telecommunications services to approximately
22,400 customers in Houston, Dallas, Fort Worth, San Antonio and Austin, of
which approximately 16,400 are business customers.
 
    On June 12, 1998, the Company consummated the offering of the Old Notes (the
"Offering") and received net proceeds of approximately $338 million. Of these
proceeds approximately $122 million (including premiums of approximately $.8
million) were used to purchase securities which secure the first six interest
payments on the Notes, $126.5 million were used to finance the American Telco
Acquisition (together with a previous $5 million earnest money deposit) and the
balance will be used for general corporate purposes.
 
SERVICES STRATEGY
 
    The Company's objective is to be the dominant alternative provider of
integrated local, long distance and data services packaged with wireless
offerings to small and medium-sized business customers in the Southwest. The
Company has developed customer focused strategies to build market share in
existing and new markets while utilizing innovative and efficient network
deployment techniques to maximize customer satisfaction and financial returns.
The principal elements of the Company's services strategy include:
 
    DELIVERING INNOVATIVE TELECOMMUNICATIONS SOLUTIONS FOR BUSINESS
    CUSTOMERS.  The Company believes that there is substantial demand from small
    and medium-sized businesses for bundled telecommunications services provided
    on a single monthly bill and with a single point of contact for all sales
    and service. Under its LOGIX-TM- brand name, the Company offers local, long
    distance, enhanced data, Internet, wireless and systems integration services
    to customers with convenient integrated billing through its "DIRECT T-SM-"
    bundled service offering.
 
    FOCUSING ON THE SOUTHWEST.  In order to leverage its extensive
    telecommunications networks and long-standing customer and business
    relationships in the region, the Company intends to continue to focus on the
    Southwest, initially targeting Oklahoma and Texas. The Company believes that
    this regional
 
                                       1
<PAGE>
    focus will enable it to take advantage of economies of scale in management,
    network operations, sales and marketing.
 
    BUILDING MARKET SHARE THROUGH DIRECT SALES AND SUPERIOR CUSTOMER
    SERVICE.  The Company believes that the key to revenue growth in its target
    markets is to acquire customers through direct sales efforts and retain
    those customers by offering a high level of customer service. The Company
    believes that, in servicing the small and medium-sized business market,
    using a consultative, face-to-face sales and service strategy with a single
    point of contact is a highly effective method of acquiring customers and
    developing long-term customer relationships.
 
    INCREASING PRODUCTIVITY AND EFFICIENCY THROUGH CONTINUED ENHANCEMENT OF
    OSS.  The Company believes that fully integrated and scalable operations
    support systems ("OSS") will increase productivity and efficiency and
    provide a competitive advantage. The Company currently deploys tailored
    systems and procedures for its OSS and other back office systems and
    customer service, and intends to replace its existing OSS with a fully
    integrated, scalable system which can be expanded as the Company grows its
    customer base.
 
NETWORK STRATEGY
 
    The Company will seek to efficiently expand its network infrastructure to
offer facilities-based services in attractive markets while minimizing its up
front capital expenditures. The principal elements of the Company's network
strategy include:
 
    MAXIMIZING OPERATING MARGINS WITH A TARGETED SERVICE AREA.  The Company
    targets customers within a specified geographic zone surrounding its network
    infrastructure, thereby controlling the cost of services. By focusing its
    sales efforts on customers within these zones and bypassing the ILEC's, the
    Company believes it can generate higher gross margins than could be obtained
    by reselling ILEC services.
 
    EMPLOYING ADVANCED REMOTE SWITCHING TECHNOLOGY.  In entering new markets the
    Company intends to deploy an advanced network presence unit (an "ANP") which
    utilizes minaturized switching technology. As customer telecommunications
    traffic warrants, the Company will install a Class V switch and redeploy
    ANPs to a new market area. By using ANP units and Class V switches, the
    Company believes it will have lower operating costs than reselling.
 
    CONTROLLING SERVICE QUALITY.  The Company's strategy is to have direct
    control of the quality of service and responsiveness to its customers by
    utilizing the Company's own switches and providing a direct connection which
    eliminates the reliance on other switching providers, in contrast to
    reselling.
 
LEVERAGING EXISTING OPERATIONS AND PROVEN MANAGEMENT TEAM
 
    The Company believes that its ability to leverage its existing local
exchange and fiber operations and to draw upon its senior management's extensive
experience and expertise in facilities-based telecommunications services will
provide it with a competitive advantage. Collectively, the executives of the
Company have in excess of 125 years of telecommunications experience.
 
                                  RISK FACTORS
 
   
    An investment in the Notes involves a high degree of risk. The risks that a
potential investor should consider before making an investment in the Notes
include, but are not limited to, risks associated with: (i) the Company's
leverage and its ability to meet required debt service; (ii) the Company's
significant capital requirement associated with its operations; (iii) covenant
restrictions contained in instruments governing the Company's indebtedness,
including the Notes; (iv) the negative impact on Adjusted EBITDA from CLEC

rights-of-way and other third-party agreements; (xi) the Company's dependence
upon billing, customer service and information systems; (xii) the year 2000
issue; (xiii) competition; (xiv) rapid technological changes; (xv) the
dependence of the Company on its key personnel; (xvi) regulation; (xvii)
fraudulent conveyance statutes; (xviii) the absence of a public market for the
notes and restrictions on the transferability of the Old Notes; and (xix) the
control of the Company by Dobson Communications Corporation. See "Risk Factors."

(1) Extraordinary items reflect expense associated with early extinguishment of
    debt, net of income tax benefit.
 
(2) Cumulative effect of change in accounting principle reflects the charge
    taken, net of income tax benefit, as a result of the implementation of AICPA
    Statement of Position 98-5 "Reporting on the Costs of Start-up Activities,"
    effective January 1, 1998.
 
(3) ICP revenue includes network management services provided to affiliates of
    Logix. For 1995 and 1996 and the three months ended June 30, 1997, the
    network management services account for all of the ICP revenue and for 1997
    and the six months ended June, 1998, for $124,000 and $35,200 of the ICP
    revenue, respectively.
 
   
(4) Adjusted EBITDA represents earnings before interest expense, income taxes,
    depreciation and amortization, other income, extraordinary items, and
    changes in accounting principles. Adjusted EBITDA is provided because it is
    a measure commonly used in the industry and by the Company to assess a
    company's operating performance and its ability to incur or service debt. In
    addition, the Indenture governing the Notes contains certain covenant
    requirements that are based on Adjusted EBITDA. See "Description of the
    Notes--Covenants." Adjusted EBITDA is not derived pursuant to generally
    accepted accounting principles and should not be construed as an alternative
    to net income, as a measure of performance, or to cash flows, as a measure
    of liquidity. Adjusted EBITDA, as measured by the Company, may differ
    significantly from similarly named measurements of other companies and, as a
    consequence, may not provide any degree of reliable comparability. The
    calculation of Adjusted EBITDA does not include the Company's commitments
    for capital expenditures or payments of debts and should not be deemed to
    represent funds available to the Company.
    
 
(5) For the six months ended June 30, 1998, earnings were insufficient to cover
    fixed charges by $5.8 million. "Earnings" is defined as earnings before
    extraordinary items, accounting changes and fixed charges. Fixed charges
    consist of interest expense, amortization of deferred financing costs,
    income taxes and a portion of rent expense under operating leases
    representative of interest.
 
(6) Route miles refers to the number of miles over which fiber optic cables are
    installed.
 
(7) Fiber miles refers to the number of route miles multiplied by the number of
    fibers installed along that path.

<PAGE>
                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS, THE
FOLLOWING RISK FACTORS SHOULD BE CAREFULLY CONSIDERED BY PROSPECTIVE INVESTORS
IN EVALUATING THE COMPANY AND ITS BUSINESS.
 
LEVERAGE; ABILITY TO MEET REQUIRED DEBT SERVICE
 
   
    The Company is highly leveraged. At June 30, 1998, the Company had $378.0
million of indebtedness and stockholder's equity of $14.3 million. On a pro
forma basis, after giving effect to the American Telco Acquisition and the
Offering as if they had occurred on January 1, 1997, for the year ended December
31, 1997, and the six months ended June 30, 1998, the Company's Adjusted EBITDA
minus interest expense and capital expenditures other than acquisition costs
incurred in the American Telco Acquisition would have been $(43.8) million and
$(26.8) million, respectively. For the year ended December 31, 1997, and the six
months ended June 30, 1998, on a pro forma basis, after giving effect to the
American Telco Acquisition and the Offering, the Company's earnings would have
been insufficient to cover fixed charges by $51.2 million and $27.7 million,
respectively, and Adjusted EBITDA would have been insufficient to cover interest
expense by $34.3 million and $19.3 million, respectively. See Note 4 of the
Notes to Selected Consolidated Financial and Other Data and "Description of
Certain Indebtedness."
    
 
    The Company experienced a substantial increase in total indebtedness and
debt service requirements as a result of the American Telco Acquisition and the
Offering. The successful implementation of the Company's strategies, including
the expansion of its network, operations and systems, and sustained growth in
its cash flow will be necessary for the Company to meet its debt service
requirements, including those under the Notes. There can be no assurance that
the Company will successfully implement its strategies or that the Company will
be able to generate sufficient cash flow from operating activities to meet its
debt service and working capital requirements.
 
    If the Company is unable to generate sufficient cash flow or otherwise
obtain funds necessary to make required payments, or if the Company otherwise
fails to comply with the various covenants in its existing or future debt
obligations, it would be in default under the terms thereof, which would permit
the holders of such indebtedness to accelerate the maturity of such indebtedness
and could cause defaults under other indebtedness of the Company. Such defaults
could result in a default on the Notes and could delay or preclude payment of
interest on or principal of the Notes. The Company's ability to meet its
obligations will depend upon the future performance of the Company, which will
be subject to prevailing economic conditions and to financial, business and
other factors.
 
    The level of the Company's indebtedness could adversely affect the Company
in a number of ways. For example, (i) the ability of the Company to obtain any
necessary financing in the future for working capital, capital expenditures,
debt service requirements or other purposes may be limited; (ii) the level of
its indebtedness could limit the Company's flexibility in planning for, or
reacting to, changes in its business; (iii) the Company will be more highly
leveraged than some of its competitors, which may place it at a competitive
disadvantage; (iv) the Company's degree of indebtedness may make it more
vulnerable to a downturn in its business or the economy generally; (v) the debt
service requirements of any additional indebtedness could make it more difficult
for the Company to make payments required by the Notes; and (vi) a substantial
portion of the Company's cash flow from operations must be dedicated to the
payment of principal and interest on its indebtedness and will not be available
for other purposes.
 
SIGNIFICANT CAPITAL REQUIREMENTS
 
    Expansion of the Company's network, operations and services will require
significant capital. The Company has budgeted total capital expenditures,
excluding acquisitions, of approximately $58.1 million for 1998 and
approximately $23.5 million in 1999, and anticipates substantial capital
expenditures thereafter. Budgeted capital expenditures will be primarily for:
(i) the expansion of the Company's facilities-based ICP services including
acquisition and installation of switches; (ii) market expansion; and (iii)
infrastructure enhancements, principally for OSS. The Company believes that cash
on hand, cash flow
 
                                       11
<PAGE>
from operations and borrowings under the RUS/RTB Facility (as defined herein),
will provide sufficient funds to enable the Company to fund the replacement of
its OSS and the expansion of its business as currently planned, including its
negative cash flows from its ICP services. The actual amount and timing of the
Company's future capital requirements may differ materially from the Company's
estimate depending on the demand for the Company's services and as a result of
regulatory, technological and competitive developments (including new market
developments and new opportunities) in the Company's industry. The Company may
also require additional capital in the future (or sooner than currently
anticipated) for new business activities related to its current and planned
businesses, or in the event it decides to make additional acquisitions or enter
into joint ventures and strategic alliances. Sources of additional capital may
include cash flow from operations and public and private equity and debt
financings, including vendor financing. There can be no assurance, however, that
the Company will be successful in producing sufficient cash flows or raising
sufficient debt or equity capital to meet its strategic objectives or that such
funds, if available at all, will be available on a timely basis and within the
limitations contained in the Indenture and the terms of the Company's other
existing or future indebtedness or on terms that are acceptable to the Company.
Failure to generate or raise sufficient funds would require the Company to delay
or abandon some or all of its future expansion plans or expenditures, which
could limit the ability of the Company to meet its debt service obligations
(including obligations under the Notes) and could have a material adverse effect
on the Company. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources" and "Description of
Certain Indebtedness."
 
COVENANT RESTRICTIONS
 
    The existing and future instruments governing the indebtedness of the
Company and its subsidiaries impose or may impose significant operating and
financial restrictions on the Company and its subsidiaries. Such restrictions
will affect, and in many respects significantly limit or prohibit, among other
things, the ability of the Company and its 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 indebtedness of Dobson Telephone Company ("Dobson
Telephone") under the RUS/RTB Facility is secured by liens upon substantially
all of Dobson Telephone's assets, and requires the maintenance of certain
financial ratios. See "Description of Certain Indebtedness." These restrictions
could also limit the ability of the Company and its subsidiaries to effect
future financings. A failure by the Company or its subsidiaries to comply with
these restrictions could lead to a default under the terms of such indebtedness
notwithstanding the ability of the Company to meet its 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 together with
accrued and unpaid interest. In such event, a significant portion of the
Company's other indebtedness may become immediately due and payable and there
can be no assurance that the Company and its subsidiaries would be able to make
such payments or borrow sufficient funds from alternative sources to make any
such payment. Even if additional financing could be obtained, there can be no
assurance that it would be on terms that are acceptable to the Company.
 
NEGATIVE IMPACT ON EBITDA FROM ICP SERVICES
 
   
    On a pro forma basis, after giving effect to the American Telco Acquisition
and the Offering, the Company would have incurred operating losses of
approximately $5.0 million and $5.2 million and have had Adjusted EBITDA of
approximately $12.2 million and $3.7 million for the year ended December 31,
1997 and for the six months ended June 30, 1998, respectively. As a result of
the continued expansion of its ICP services, the Company has and will continue
to incur significant increases in expenses associated with these activities
which will significantly reduce its Adjusted EBITDA until it can develop and
expand its ICP service customer base. There can be no assurance that an adequate
customer base will be achieved or sustained or that the Company will be able to
achieve positive cash flow or positive Adjusted EBITDA with respect to its ICP
services. The Company does not expect to achieve a significant market share for
its services.

HOLDING COMPANY STRUCTURE; ABILITY TO INCUR ADDITIONAL SECURED INDEBTEDNESS
 
    Logix Communications Enterprises, Inc. is a holding company with no direct
operations and no significant assets other than the stock of its subsidiaries.
Logix is dependent on the cash flows of its subsidiaries to meet its
obligations, including the payment of interest on and principal of the Notes.
Receipt of funds from its subsidiaries will be restricted by the terms of
existing and future indebtedness including the loan agreements with the United
States of America--Rural Utilities Service ("RUS") and the Rural Telephone Bank
("RTB") (the "RUS/RTB Facility"). See "Description of Certain Indebtedness."
Logix's subsidiaries are separate legal entities that have no obligation to pay
any amounts due with respect to the Notes or to make any funds available
therefor, whether by dividends, loans or other payments. Because Logix's
subsidiaries have not guaranteed Logix's obligations on the Notes, any right of
Logix to receive assets of any of its subsidiaries upon its liquidation or
reorganization (and the right of the holders of the Notes 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), except if and to the
extent the Company is itself a creditor of such subsidiary, in which case the
claims of the Company would still be effectively subordinated to any security
interest in the assets of such subsidiary senior to that held by the Company.
The indebtedness of Dobson Telephone, the Company's subsidiary that conducts it
ILEC business, under the RUS/RTB Facility is secured by substantially all of
Dobson Telephone's assets. Accordingly, the Notes will be effectively
subordinated to the liabilities (including trade payables and indebtedness under
the RUS/RTB Facility) of the subsidiaries of the Company. See "Description of
Certain Indebtedness."
 
    The Notes will be general unsecured, unsubordinated indebtedness of the
Company. At June 30, 1998, the Company and its subsidiaries had outstanding
approximately $378.0 million aggregate principal amount of indebtedness. In the
event the Company obtains additional funds through the incurrence of secured
indebtedness and a default were to occur with respect to any such indebtedness,
the holders of such indebtedness would be entitled to payment out of the
proceeds of their collateral prior to the holders of general unsecured
indebtedness, including the Notes, notwithstanding the existence of an event of
default with respect to the Notes. In the event of a bankruptcy, liquidation or
reorganization of the Company, holders of secured indebtedness would have a
claim, prior to the holders of the Notes, on the assets of the Company securing
such indebtedness. In addition, to the extent that the value of the collateral
is insufficient to satisfy such secured indebtedness, holders of amounts
remaining outstanding on such secured indebtedness would be entitled to share
with respect to any other assets of the Company on a pro rata basis with the
Notes. Assets remaining after satisfaction of the claims of holders of secured
indebtedness may not be sufficient to pay amounts due on any or all of the Notes
then outstanding. The Indenture will permit the Company to incur additional
indebtedness and to secure such indebtedness.
 
RISKS ASSOCIATED WITH ACQUISITIONS; ABILITY TO MANAGE GROWTH
 
    The Company is subject to risks that acquired businesses, including American
Telco, will not perform as expected and that the returns from such acquisitions
will not support indebtedness incurred to effect such acquisition or the capital
expenditures needed to develop and expand the systems acquired in the
acquisitions. Expansion of the Company's operations may also place a significant
strain on the Company's management, financial and other resources, and in the
case of acquisitions, divert the resources and management time of the Company.
In addition, the integration of acquired systems with existing operations may
cause the Company to incur considerable expense in advance of anticipated
revenues and may cause substantial fluctuations in the Company's operating
results. This integration 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 the Company's existing systems. Other integration risks include the
difficulty in assimilating the acquired operations and personnel, the potential
disruption of the Company's ongoing business, the possible inability of
management to maintain uniform standards,
 
                                       13
<PAGE>
controls, procedures and policies and the potential impairment of relationships
with employees or customers as a result of changes in management.
 
    The expansion and development of the Company's business will depend on,
among other things, the Company's ability to successfully implement its sales
and marketing strategy, evaluate markets, secure financing, obtain required
government authorizations, implement interconnection to, and collocation with,
facilities owned by ILECs, obtain appropriately priced unbundled network
elements and wholesale services from the ILECs, purchase and install switches in
new markets, provision new customers, and implement efficient operating support
systems and other back office systems, all in a timely manner, at reasonable
cost, and on satisfactory terms and conditions. The Company's ability to
continue to successfully manage its growth will require the Company to enhance
its operational, management, financial and information systems and controls and
to hire and retain qualified sales, marketing, administrative, operating and
technical personnel, all of which will result in higher operating expenses. In
addition, as the Company increases its service offerings and expands its
targeted markets, there will be additional demands on customer support, sales
and marketing, administrative resources and network infrastructure. Any failure
to expand these areas and to implement and improve the acquired and existing
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. There
can be no assurance that the Company will be able to successfully integrate the
American Telco Acquisition or any other businesses it may acquire, that any
acquired business will perform as expected or that any such acquired business
will not experience high employee or customer turnover rates after the
acquisition. The Company's inability to manage its growth effectively or
implement its expansion and growth strategy successfully could have a material
adverse effect on the Company's business, results of operations and financial
condition.
 
DEPENDENCE ON ILECS
 
    The Company is dependent on ILECs to provide access service for the
origination and termination of its toll long distance traffic and interexchange
private lines. Historically, charges for such access service have represented a
significant percentage of the overall cost of providing long distance service.
In May 1997, the FCC adopted changes to its interstate access rules that, among
other things, will reduce per-minute access charges and substitute new per-line,
flat rate monthly charges. The FCC also approved reductions in overall access
rates, and established new rules to recover subsidies to support universal
service and other public policies. The impact of these changes on the Company or
its competitors is not yet clear. The Company could be adversely affected if it
does not experience access cost reductions or is not charged per-line monthly
charges in a manner proportionally equivalent to those of its competitors.
 
    The Company, generally, will be dependent on ILECs for provision of
competitive local telephone service through access to local loops and
origination and termination service and, in some markets, central office
switches of such carriers. Any successful effort by the ILECs to deny, delay or
substantially limit the Company's access to these unbundled network elements or
wholesale services would have a material adverse effect on the Company's ability
to provide local telephone services. Although the Telecommunications Act of 1996
(the "Telecommunications Act") imposes interconnection obligations on ILECs,
there can be no assurance that the Company will be able to obtain access to such
network elements or services at rates, and on terms and conditions, that permit
the Company to offer local services at rates that are both profitable and
competitive. The Eighth Circuit Court of Appeals recently struck down certain
FCC rules intended to govern such rates, terms and conditions. See
"--Regulation." One result of this decision is to give state utility commissions
a principal role in implementing ILEC's interconnection obligations under the
Telecommunications Act. It is uncertain whether such commissions will adopt and
enforce rules or take other actions that will permit new carriers to have
economical use of incumbent local exchange carrier networks and facilities. The
Company's interconnection agreements with SBC and GTE (the "Interconnection
Agreements") allow the Company to provide local service on a resale basis or by
purchasing all unbundled network elements required to provide local service on a
facilities basis. The terms of the
 
                                       14
<PAGE>
Interconnection Agreements, including interim pricing terms agreed to by the
Company and SBC and GTE, have been approved by state regulatory authorities in
Oklahoma and Texas, although they remain subject to review and modification by
such authorities. In addition, the Interconnection Agreements do not resolve all
operational issues which issues the Company and SBC and GTE continue to
negotiate to resolve. Also, many issues relevant to the terms and conditions by
which competitors may use the ILEC network and wholesale services remain to be
resolved. For example, SBC and certain other ILECs have taken the position that
when a carrier seeking to provide local service obtains all necessary elements
(loops and switches) from the ILEC, the ILEC retains the right to receive the
access revenues associated with the access service to the customers served on
that basis. Although the FCC has rejected this position, further legal
challenges are in progress and other important issues related to this form of
interconnection remain open. Many new carriers, including the Company, have
experienced problems with respect to provisioning, interconnection and the
operational support systems used by new carriers to order and receive network
elements and wholesale services from the ILECs. These systems are necessary for
new carriers like the Company to provide local service to customers on a timely
and competitive basis. The FCC has created a task force to examine problems that
have slowed the development of local telephone competition. The
Telecommunications Act creates incentives for the Regional Bell Operating
Companies ("RBOCs") such as SBC to permit access to their facilities by denying
such carriers the ability to provide long distance services until there is
adequate competition at the local level. However, the U.S. District Court for
the Northern District of Texas has found these provisions unconstitutional (the
"SBC Decision"), but this order has been stayed pending appeal. SBC is not yet
permitted to offer long distance services in any state in its region. There can
be no assurance, however, that SBC or other RBOCs will be accommodating to the
Company once they are permitted to offer in-region long distance service. Should
the Company be unable to obtain the cooperation of an ILEC in a region, whether
or not such ILEC has been authorized to offer long distance service, the
Company's ability to offer local services in such region on a timely and cost-
effective basis would be adversely affected. See "Business--Services" and
"--Regulation."
 
RISKS RELATED TO LOCAL SERVICES STRATEGY
 
    The Company has recently entered the competitive local telecommunications
services industry. The local telephone services market has only recently been
opened to competition through the passage of the Telecommunications Act and
subsequent state and federal regulatory actions designed to implement the
Telecommunications Act. Regulatory bodies, including state commissions and the
FCC, have not completed all actions needed to implement the local service
competition provisions of the Telecommunications Act, and there is little
experience under those decisions that have been made to date. The Company must
continue to make significant operating and capital investments and marketing and
advertising expenditures in order to implement its local exchange services
strategy. There are numerous operating complexities associated with providing
these services. The Company will be required to develop new products, services
and systems, and new marketing initiatives, and to train its sales force in
connection with selling these services. The Company is replacing its existing
OSS with a scalable OSS to manage the expanding business as well as to stay
competitive. The Company will face significant competition from ILECs, whose
core business is providing local dial tone service. The ILECs, who currently are
the dominant providers of services in their markets, are expected to mount a
significant competitive response to new entrants in their markets such as the
Company. The Company also will face significant competitive product and pricing
pressures from other ILECs and from other firms seeking to compete in the local
services market outside of their respective regions and historical markets.
 
    The Company expects that the continued roll-out of its ICP services will
have an adverse impact on its gross margin because the gross margin on its ICP
services is lower than the gross margin on its fiber and ILEC services. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Revenue."
 
                                       15
<PAGE>
PRICING PRESSURES AND RISKS RELATING TO LONG DISTANCE BUSINESS
 
    The long distance transmission industry has generally been characterized by
over-capacity and declining prices since shortly after the AT&T divestiture in
1984. The long distance business is extremely competitive, and prices have
declined substantially in recent years and are expected to continue to decline.
The Company is aware that certain long distance carriers are expanding their
capacity and believes that other long distance carriers, as well as potential
new entrants to the industry, are constructing new fiber optic and other long
distance transmission networks in the southern and southwestern United States.
In addition, the long distance industry has historically had a high average
churn rate, as customers frequently change long distance providers in response
to the offering of lower rates or promotional incentives by competitors. Since
the cost of the actual fiber (as opposed to construction costs) is a relatively
small portion of the cost of building new transmission lines, persons building
such lines are likely to install fiber that provides substantially more
transmission capacity than will be needed over the short or medium term.
Further, recent technological advances may greatly expand the capacity of
existing and new fiber optic cable. Although such technological advances may
enable the Company to increase its capacity, an increase in the capacity of the
Company's competitors could adversely affect the Company's long-haul fiber
business. If industry capacity expansion results in capacity that exceeds
overall demand along any of the Company's long-haul fiber routes, severe
additional pricing pressure could develop. In addition, strategic alliances or
similar transactions, such as the long distance capacity purchasing alliance
among certain RBOCs announced in the spring of 1996, could result in additional
pricing pressure on long distance carriers. Furthermore, the marginal cost of
carrying an additional call over existing fiber optic cable is extremely low. As
a result, within a few years, there may be dramatic and substantial price
reductions. See "--Competition."
 
    In addition to supplying long-haul fiber capacity, the Company relies on
other carriers to provide transmission and termination services for its long
distance traffic. The Company has resale agreements with long distance carriers
to provide it with transmission services. Such agreements typically provide for
the resale of long distance services on a per minute basis, with some agreements
containing minimum volume commitments. Negotiation of these agreements involves
estimates of future supply and demand for transmission capacity as well as
estimates of the calling pattern and traffic levels of the Company's future
customers. In the event the Company fails to meet its minimum volume
commitments, it may be obligated to pay underutilization charges, and in the
event it underestimates its need for transmission capacity, the Company may be
required to obtain capacity through more expensive means. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--Costs
and Expenses."
 
DEPENDENCE ON LEASED TRUNKING CAPACITY; FUTURE NEED TO OBTAIN PERMITS,
  RIGHTS-OF-WAY, AND OTHER THIRD-PARTY AGREEMENTS
 
    Under its competitive local services strategy, the Company will initially
lease from ILECs and other ICPs local fiber trunking capacity connecting the
Company switch to particular ILEC central offices. In some instances, the
Company may replace this leased trunk capacity in the future with its own fiber
if warranted by traffic volume growth. There can be no assurance that all such
required trunking capacity will be available to the Company on a timely basis or
on terms acceptable to the Company. The failure to obtain such leased fiber
could delay the Company's ability to penetrate certain market areas or require
it to make additional, unexpected up-front capital expenditures to install its
own fiber and could have a material adverse effect on the Company and its
ability to meet its obligations on the Notes. If and when the Company seeks to
install its own fiber, the Company must obtain local franchises and other
permits, as well as rights-of-way to utilize underground conduit and aerial pole
space and other rights-of-way from entities such as ILECs and other utilities,
railroads, long distance companies, state highway authorities, local government
and transit authorities. There can be no assurance that the Company will be able
to obtain and maintain the franchises, permits and rights needed to implement
its network buildout on acceptable terms. The failure to enter into and maintain
any such required arrangements for a particular network may affect the Company's
ability to develop that network and may have a material adverse effect on the
Company.
 
                                       16
<PAGE>
DEPENDENCE ON BILLING, CUSTOMER SERVICE AND INFORMATION SYSTEMS
 
    Sophisticated information and processing systems are vital to the Company's
growth and its ability to monitor costs, bill customers, provision customer
orders and achieve operating efficiencies. Billing and customer service and
information systems for Logix's ILEC and ICP services are provided by third
party vendors. The inability of the Company to obtain these services from third
parties or the failure of these third parties to provide adequate services could
have a material adverse effect on the Company. As the Company expands its ICP
operations and integrates the operations of American Telco with existing
operations, the need for enhanced billing, customer service and information
systems will increase significantly. The Company's plans for the replacement of
its OSS, for the most part, depend on the Company's retention of appropriate
third party vendors that can provide products and services that meet the
Company's needs and deliver such products and services. Integrating American
Telco's customers into a new billing system and implementing any new OSS
involves inherent risks and often there are delays and errors. For example, in
connection with the commencement of its ICP services, American Telco initially
experienced problems with its billing systems resulting in customer billings
which were less than 100% of charges. Errors or delays in integrating and
implementing a new billing program or OSS, failure of the Company's vendors to
deliver proposed products and services in a timely and effective manner and at
acceptable costs or the inability of the Company to identify adequately all of
its information and processing needs, or to upgrade systems as necessary, could
have a material adverse impact on the ability of the Company to reach its
objectives and on its financial condition and results of operations and on its
ability to pay interest and principal on the Notes.
 
RISKS ASSOCIATED WITH THE YEAR 2000 ISSUE
 
    The Year 2000 issue is the result of computer programs using two digits
rather than four to define the applicable year. Date-sensitive software may
recognize a date using "00" as the year 1900 rather than the Year 2000. This
could result in system failures or miscalculations causing disruptions of
operations, including, among others, a temporary inability to process
transactions, send invoices, or engage in similar normal business activities.
 
    To date, the Company has completed an inventory of its automated systems and
services and an analysis that identified significant risk areas by line of
business, identified specific compliance requirements, and identified costs and
estimated completion dates for affected systems. 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 acquired
companies. Management has determined that American Telco's OSS is not Year 2000
compliant; however, the Company believes its new OSS which will replace American
Telco's, will be Year 2000 compliant and will be in place by 2000. As a result,
the remediation approach is not focused on a large scale in-house effort, but on
identifying those systems and services that are not currently Year 2000
compliant and either upgrading to a compliant version or replacing with an
alternative compliant product or service. The Company's analysis revealed that
for most of the Company's information systems, services and telecommunications
infrastructure, Year 2000 compliant releases 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 by the second quarter of 1999. The total costs
identified to upgrade or replace those systems that are not Year 2000 compliant
and will not be upgraded through existing maintenance or service agreements are
approximately $.1 million. Additionally, such costs will be expensed as
incurred, which will have an adverse effect on the current operating results.
 
    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, customers and others with which it does business to coordinate Year
2000 compliance. To
 
                                       17
<PAGE>
further mitigate risks, the Company will conduct its own Year 2000 tests on
mission critical systems as their Year 2000 compliant versions are released by
vendors.
 
COMPETITION
 
    The Company operates in a highly competitive environment, and the level of
competition, particularly with respect to pricing, is increasing. Local
telephone and telecommunications services originating and terminating in the
same local access and transport area ("intraLATA") substantially similar to
those offered by the Company are also offered by the ILECs serving the markets
that the Company currently serves and plans to serve. SBC Communications, Inc.
("SBC") is the ILEC and a particularly strong competitor in most of the markets
currently served by the Company. SBC and other ILECs already have long standing
relationships with their customers and can marshall greater technical and
financial resources. SBC and other ILECs have the potential to subsidize
services of the type offered by the Company from service revenues not subject to
effective competition, which could result in even more intense price
competition. The Company also faces, and expects to continue to face,
competition from other current and potential market entrants, including long
distance carriers seeking to enter, reenter or expand entry into the local
exchange marketplace (such as AT&T, MCI, Sprint and WorldCom), from RBOCs
operating outside their current local service regions, other ICPs, resellers,
competitive access providers ("CAPs"), cable television companies, electric
utilities, microwave carriers, wireless telephone system operators and private
networks built by large end users. In addition, the development of new
technologies could give rise to significant new competitors to the Company. See
"--Dependence on ILECs."
 
    The Company competes with long distance carriers in the provision of
interLATA long distance retail and wholesale carriers' carrier services. The
long distance market for telecommunications services orginating in one local
access and transport area ("LATA") and ending in another LATA ("interLATA")
consists of numerous competitors including AT&T, Sprint Corporation ("Sprint"),
MCI WorldCom ("WorldCom"), IXC Communications, Inc., Qwest Communications
International Inc. ("Qwest") and Excel Communications, Inc. ("Excel"). Other
competitors of the Company in the retail and carrier services markets are likely
to include RBOCs providing out-of-region (and, with the future removal of
regulatory barriers, in-region) long distance services, other competitive local
exchange carriers, microwave and satellite carriers, and private networks owned
by large end-users. The Company also may increasingly face competition from
firms offering long distance data and voice services over the Internet. Such
firms could enjoy a significant cost advantage because at this time they are not
required to pay carrier access charges or universal service fees. In addition,
the Company competes with direct marketers, equipment vendors and installers,
and telecommunications management companies with respect to certain portions of
its business. Many of the Company's existing and potential competitors have
financial, technical and other resources and customer bases and name recognition
far greater than those of the Company. The long distance business is extremely
competitive and prices have declined substantially in recent years and are
expected to continue to decline, which will adversely affect the Company's gross
margins as a percentage of revenues. In 1997, the FCC announced changes to its
interstate access rules that will reduce per-minute access charges and
substitute new per-line flat-rate monthly charges. These actions are expected to
reduce access rates. AT&T has committed to reducing its long distance rates to
reflect access cost reductions, and other competitors of the Company are likely
to make similar reductions. In such event, the Company may need to reduce its
rates to respond to competitive pressures. See "Business--Regulation."
 
    The Telecommunications Act, other recent state legislative actions, and
current federal and state regulatory initiatives provide increased business
opportunities for the Company by removing or substantially reducing barriers to
local exchange competition. However, these new competitive opportunities are
expected to be accompanied by new competitive opportunities for the ILECs. It is
also expected that increased local competition will result in increased pricing
flexibility for, and relaxation of regulatory oversight of, the ILECs. If the
ILECs are permitted to engage in increased volume and discount pricing practices
or charge competitive local exchange carriers increased fees for interconnection
to their networks, or if the ILECs seek to delay implementation of
interconnection by competitors to their networks,
 
                                       18
<PAGE>
the Company's results of operations and financial condition could be adversely
affected. For example, the FCC recently provided that pre-subscribed interchange
carrier charges (or "PIC-C charges") would be required to be paid by long
distance carriers to the local exchange carriers which are intended to partially
offset lowered interstate access rates. There can be no assurance that the
Company will be able to achieve or maintain adequate market share or revenues,
or compete effectively in any of its markets.
 
    The Company believes that the principal competitive factors affecting its
business operations are price, quality, reliability, billing and customer
service and responsiveness, and service features. The ability of the Company to
compete effectively will depend upon its continued ability to maintain high
quality, market-driven services at prices generally equal to or below those
charged by its competitors. To maintain its competitive posture, the Company
believes that it must be in a position to reduce its prices in order to meet
reductions in rates, if any, offered by others. Any such reductions could
adversely affect the Company.
 
    In addition, the recent trend toward mergers and strategic alliances among
RBOCs and larger telecommunications carriers since passage of the
Telecommunications Act raises serious questions about the adverse effect of
these mergers and alliances upon the development of competition in the
telecommunications industry. On June 24, 1998, AT&T announced its proposed
acquisition of Tele-Communications, Inc. On May 11, 1998, SBC and Ameritech
announced their merger which, if approved, would reduce the seven original RBOCs
to four. If approved, this merger would leave one RBOC, SBC, with control of a
significant portion of local exchange and business access lines in the U.S. It
also will significantly reduce competition between RBOCs, such as Ameritech's
previously announced plans to launch local service in Texas and St. Louis,
Missouri in 1998 and in other markets within SBC's region. At the same time,
SBC's competitors have won less than two percent of SBC's market share in its
local markets as a whole. SBC already has merged with Pacific Bell, and a merger
with Southern New England Telecommunications in Connecticut is pending. Two
other RBOCs, Bell Atlantic and NYNEX, have also merged. Worldcom has acquired
MFS Communications Co., Inc., Brooks Fiber Properties, Inc. and MCI. In January
1998, AT&T announced plans to acquire another ICP, Teleport Communications Group
Inc. ("Teleport"). In June 1998, Qwest acquired LCI. On May 6, 1998 US WEST
Communications, Inc. ("US WEST") announced that it had entered into a marketing
arrangement with Qwest whereby US WEST would market Qwest long distance services
to US WEST's in-region customers. One week later, Ameritech announced a similar
marketing arrangement with Qwest to market long distance services to Ameritech's
in-region customers. On May 14 and 15, 1998 a coalition of ICPs and
interexchange carriers filed suits in federal district courts in Seattle and
Chicago seeking a declaratory ruling that US WEST and Ameritech are providing
long distance services in violation of the Telecommunications Act. The
plaintiffs are seeking a preliminary and final injunction prohibiting US WEST
and Ameritech from marketing in their regions the long distance services of
Qwest or any other long distance carrier. On June 4, 1998, the federal district
court in Seattle granted the coalition's request for a preliminary injunction
preventing US WEST from marketing to additional customers under its Qwest
teaming agreement. On June 10, 1998, the federal district court in Chicago
denied a preliminary injunction of the Ameritech/Qwest joint marketing
agreement; however, on June 30, 1998, the FCC ordered Ameritech to cease
marketing Qwest long distance service for 90 days while the FCC rules on the
legality of the joint marketing agreement. In March 1997 BellSouth and
International Business Machines Corporation ("IBM") also announced an alliance
to provide Internet and intranet services to businesses in the southern United
States.
 
    To complement its telecommunications services offerings, the Company offers
data transmission services. The data transmission business is extremely
competitive and prices have declined substantially in recent years and are
expected to continue to decline. The Company's competitors in this market
include Internet service providers ("ISPs"), other telecommunications companies,
online service providers and Internet software providers. Many of the Company's
competitors have greater financial, technological, marketing, personnel and
other resources than those available to the Company. The profitability of the
Company's Internet access services may be adversely affected by its ability to
obtain "peering" arrangements with ISPs. In recent years, major ISPs routinely
exchanged traffic with other ISPs that met certain
 
                                       19
<PAGE>
technical criteria on a "peering" basis, meaning that each ISP accepted traffic
routed to Internet addresses on its system from its "peers" on a reciprocal
basis, without payment of compensation. In 1997, however, UUNET Technologies,
Inc. ("UUNET"), the largest ISP, announced that it intends to greatly restrict
its use of peering arrangements with other providers, and would impose charges
for accepting traffic from providers other than its "peers." Other major ISPs
have reportedly adopted similar policies. There can be no assurance that the
Company will be able to negotiate "peer" status with any of the major nationwide
ISPs, or that it will be able to terminate traffic on ISPs' networks at
favorable prices. In addition, the merger between WorldCom (UUNET's parent) and
MCI (another major ISP) is expected to increase the concentration of market
power to ISP backbone services, and may adversely affect the Company's ability
to obtain favorable peering terms.
 
    In February 1998, US WEST, Bell Atlantic and Ameritech, petitioned the FCC
under Section 706 of the Telecommunications Act to allow them to build and
operate packet- and cell-switched data networks across LATA boundaries, to
permit them to carry interLATA data traffic incident to their provision of
digital subscriber line services, to not require them to make those data
services available on a discounted resale basis, and to not require them to make
the non-bottleneck elements of such services available on an unbundled basis.
The Company provides or may provide certain services with which these proposed
services (or similar services offered by other RBOCs) would compete if these
petitions are granted by the FCC.
 
    The recent World Trade Organization ("WTO") agreement on basic
telecommunications services could increase the level of competition faced by the
Company. Under this agreement, the United States and 72 other members of the WTO
committed themselves to opening their telecommunications markets to competition
and foreign ownership and to adopting regulatory measures to protect against
anticompetitive behavior by dominant telephone companies effective in some cases
as early as January 1, 1998.
 
    The Company also believes that providers of wireless services increasingly
will offer, in addition to products that supplement a customer's wireline
communications (similar to cellular telephone services in use today), wireline
replacement products that may result in wireless services becoming the
customer's primary mode of communications. Competition with providers of
wireless telecommunications services may be intense. Many of the Company's
potential wireless competitors have substantially greater financial, technical,
marketing, sales, manufacturing and distribution resources than those of the
Company. Furthermore, the FCC has made spectrum available through public auction
over the past several years and most recently in early 1998 for use in wireless
communications. This additional spectrum is intended by the FCC to be used for
broadband, data and video and transmission but its use in wireless local loop is
also possible.
 
    In connection with the Company's fiber business, its competitors may build
additional fiber capacity in the geographic areas served by the Company's fiber
optic operations. The Company believes that other companies are building new
nationwide long-haul fiber optic networks. In addition, many telecommunications
companies are acquiring switches, and users of switches will have an increasing
number of alternative providers of switched long-distance services. The Company
competes primarily on the basis of price, availability, transmission quality,
customer service and a variety of other services. The ability of the Company to
compete effectively in the fiber business will depend on its ability to maintain
high-quality services at prices generally equal to or below those charged by its
competitors.
 
RAPID TECHNOLOGICAL CHANGES
 
    The telecommunications industry is subject to rapid and significant changes
in technology. The effect of technological changes on the business of the
Company, such as changes relating to emerging wireline and wireless transmission
technologies and the use of the Internet for traditional voice, data or
broadband technology cannot be predicted, and there can be no assurance that
technological developments will not have a material adverse effect on the
Company. In addition, the Company may be required to select in advance one
technology over another, but it will be impossible to predict with any
certainty, at the time the Company is required to make its investment, which
technology will prove to be the most economic,
 
                                       20
<PAGE>
efficient or capable of attracting customer usage. There can be no assurance
that the Company will be able to obtain access to new technology on a timely
basis or on satisfactory terms. Any failure by the Company to obtain new
technology could have a material adverse effect on the Company.
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company's businesses are managed by a small number of management and
operating personnel, the loss of certain of whom could have a material adverse
effect on the Company. The Company believes that its ability to manage its
planned growth successfully will depend in large part on its continued ability
to attract and retain highly skilled and qualified operating, marketing,
financial, sales and technical personnel. The competition for qualified
personnel in the telecommunications industry is intense and there can be no
assurance that the Company will be able to hire or retain necessary personnel.
See "--Risks Associated with Acquisitions; Ability to Manage Growth."
 
REGULATION
 
    The Company is required to obtain certain authorizations from the FCC and
state public utility commissions ("PUCs") to offer certain of its
telecommunications services, as well as file tariffs for many of its services.
In October 1996, the FCC approved an order that eliminated the tariff filing
requirements for interstate domestic long distance provided by non-dominant
carriers, such as the Company. In February 1997, the U.S. Court of Appeals for
the District of Columbia Circuit stayed the FCC order pending appeal on the
merits. If the stay is lifted and the FCC order becomes effective,
telecommunications carriers such as the Company will no longer be able to rely
on the filing of tariffs with the FCC as a means of providing notice to
customers of prices, terms and conditions on which they offer interstate
services. To date the Company has not experienced significant difficulties in
receiving certification, maintaining tariffs or otherwise complying with its
regulatory obligations. The Company will face new regulatory obligations as it
enters new local telephone markets. It also is likely that state PUCs will
regulate the local telephone services offered by the Company and other
competitive local exchange carriers more heavily than competitive long distance
services have been regulated in the past. Because the FCC and the states have
yet to adopt many of the rules and policies necessary to fully implement local
telephone competition, or to respond to other related issues, it is uncertain
how burdensome these requirements will be for the Company. There can be no
assurance that the FCC or state commissions will continue to grant required
authority as the Company expands its business. If authority is not obtained or
if tariffs are not filed, or are not updated, or otherwise do not fully comply
with the tariff filing rules of the FCC or state regulatory agencies, third
parties or regulators could challenge these actions. Such challenges could cause
the Company to incur substantial legal and administrative expenses. In addition,
the Company must obtain prior FCC authorization for the provision of
international long distance services.
 
    In addition, the Company's ability to provide local telephone service is
heavily dependent upon implementation of the provisions of the
Telecommunications Act. The Telecommunications Act preempted state and local
laws to the extent that they prohibited local telephone competition, and imposed
a variety of new duties on ILECs intended to advance such competition, including
the duty to negotiate in good faith with competitors requesting interconnection
to the incumbent local exchange carrier's network. However, negotiations with
ILECs have sometimes involved considerable delays and the resulting negotiated
agreements may not necessarily be obtained on terms and conditions that are
acceptable to the Company. In such instances, the Company may petition the
proper state commission to arbitrate disputed issues. There can be no assurance
that the Company will be able to negotiate acceptable new interconnection
agreements with ILECs or that commission-arbitrated terms and conditions on the
parties in arbitration will be acceptable to the Company. Interconnection
agreements are also subject to approval by state commissions, often before the
Company can begin to utilize such agreements in that state. The Company also
faces issues related to implementation of the Interconnection Agreements.
 
    On August 8, 1996, the FCC adopted rules and policies implementing the local
competition provisions of the Telecommunications Act, including interconnection
obligations of all telecommunications carriers,
 
                                       21
<PAGE>
including obligations of ICPs and LECs, and ILEC pricing of interconnection,
unbundled elements and resold services ("Local Competition Order"). These rules,
in general, were considered favorable to new competitive entrants, but these
rules have not been fully implemented. The FCC's rules were challenged in the
federal courts by the RBOCs, GTE, large independent ILECs and state regulatory
commissions. In October 1996, the U.S. Court of Appeals for the Eighth Circuit
("Eighth Circuit") issued a stay of the implementation of certain of the FCC's
rules, and on July 18 and October 14, 1997, the Eighth Circuit issued decisions
finding that the FCC lacked statutory authority under the Telecommunications Act
for a major portion of its rules. In particular, the Eighth Circuit found that
the FCC was not empowered to establish national pricing standards governing
unbundled local network elements or wholesale local services of the ILECs, or to
require such carriers to provide network elements in a combined form. The Eighth
Circuit also struck down an FCC rule that would have enabled new entrants to
"pick and choose" from provisions of established interconnection agreements
between the ILECs and other carriers. The overall impact of the Eighth Circuit's
decision is to limit the obligations of ILECs as originally interpreted by the
FCC, materially reduce the jurisdictional role of the FCC in fostering local
competition, including its ability to take enforcement action if the
Telecommunications Act is violated, and increase the role of state utility
commissions. On January 26, 1998, the Supreme Court granted petitions by the FCC
and other parties to review the Eighth Circuit decisions. A decision from the
Supreme Court is not expected until early 1999. Meanwhile, certain state
commissions have asserted that they will be active in promoting local telephone
competition using the authority they have under the Eighth Circuit decisions,
lessening the significance of the reduced FCC role. At this time it is premature
to assess the impact of the Eighth Circuit decisions and there can be no
assurance that those decisions and related developments will not have a material
adverse effect on the Company. Indeed, a number of state commissions have set
prices for unbundled network elements that are substantially higher and
wholesale discount rates lower for resale services than the Local Competition
Orders provided on an interim basis. Furthermore, other FCC rules related to
local telephone competition remain the subject of legal challenges, and there
can be no assurance that decisions affecting those rules will not be adverse to
companies seeking to enter the local telephone market.
 
    In a related development, the FCC is considering proposed new policies and
rules that would grant the ILECs additional flexibility in the pricing of
interstate access services, and states are considering or are expected to
consider incumbent local exchange carrier requests for similar regulatory relief
with respect to intrastate services. Such flexibility is likely to come first
for services offered in the business market. Any pricing flexibility or other
significant deregulation of the ILECs could have a material adverse effect on
the Company. The Company also could be adversely affected by FCC or state
regulatory decisions affecting access charges and universal service. See
"Business--Regulation."
 
    On May 8, 1997, the FCC released an order establishing a significantly
expanded federal universal service subsidy regime (the "Universal Service
Order"). For example, the FCC established new subsidies for telecommunications
and information services provided to qualifying schools and libraries with an
annual cap of $2.3 billion and for services provided to rural health care
providers with an annual cap of $400.0 million. The FCC also expanded the
federal subsidies for local exchange telephone service provided to low-income
consumers. Providers of interstate telecommunications services, such as the
Company, as well as certain other entities, must pay for these programs. The
Company's share of these federal subsidy funds will be based on intrastate,
interstate and international "end user" gross telecommunications revenues
effective January 1, 1998. For the first two quarters of 1998, the assessment
for the rural, high cost and low income fund has been 3.19% and 3.14% of
interstate and international end user telecommunications revenues. For the same
period, the assessment for schools and libraries and rural health care funds
("S/L") was 0.76% of intrastate, interstate, and international end user
telecommunications services. However, while the FCC has proposed a slightly
lower assessment for the rural, high cost and low income fund for the third
quarter of 1998 (3.08%), the proposed S/L factor of 1.54% is more than double
the comparable rate for the second quarter. In the May 8th order, the FCC also
announced that it will soon revise its rules for subsidizing service provided to
consumers in high cost areas, which may result in further
 
                                       22
<PAGE>
substantial increases in the overall cost of the subsidy program. Several
parties have appealed the May 8th order. Such appeals have been consolidated and
transferred to the United States Court of Appeals for the Fifth Circuit where
they are currently pending. In addition, on July 3, 1997, several ILECs filed a
petition for a stay of the May 8th order with the FCC. That petition is pending,
as well as several other petitions for administrative reconsideration.
 
    On May 16, 1997, the FCC released an order revising its access charge rate
structure (the "Access Charge Reform Order"). The Access Charge Reform Order
substantially increases the costs that local exchange carriers which are subject
to the FCC's price cap rules ("price cap LECs"), recover through monthly,
non-traffic sensitive access charges and substantially decrease the costs that
price cap LECs recover through traffic sensitive access charges. In the order,
the FCC also announced its plan to bring interstate access rate levels more in
line with cost. The FCC has stated that this plan will grant price cap LECs
increased pricing flexibility upon demonstrations of increased competition (or
potential competition) in relevant markets. The manner in which the FCC further
implements this approach to the lowering access charge levels could have a
material effect on the Company's ability to compete in providing interstate
access services and on the Company's ILEC operations. An October 1997 FCC access
charge decision, for example, requires local exchange carriers to provide
interexchange carriers with certain information about the number and types of
charges they impose on interexchange carriers' presubscribed customers. Several
parties have appealed the Access Charge Reform Order. Those appeals have been
consolidated and transferred to the United States Court of Appeals for the
Eighth Circuit where they are currently pending.
 
    The Telecommunications Act potentially impacts the Company's ILEC
operations. Under previous regulations access charges contained implicit support
for high-cost areas. The FCC has initiated proceedings to overhaul the
contribution mechanism for federal support revenue. On May 16, 1997, the FCC
issued the Access Charge Reform Order that would remove implicit universal
service support from access revenues and place more emphasis for such support on
high cost support funds ("HCF") from state jurisdictions and federal universal
service funds ("USF"). To the extent reductions in access charges are not offset
by explicit universal service subsidies, this could have a material adverse
effect upon the Company's operations. Until such time as the appeals of the
Universal Service Order and/or Access Charge Reform Order are decided, there can
be no assurance of how either of these Orders will be implemented or enforced or
what effect the Orders will have on competition within the telecommunications
industry generally, or on the competitive position of the Company, in
particular.
 
    The Company's rural ILEC operations are regulated in large part by the
Oklahoma Corporation Commission (the "OCC"). The OCC sets rates, terms and
conditions of service and mandates minimum service and quality of service
requirements. Changes in the regulation of its rural local exchanges could have
a material adverse effect on the Company. Dobson Telephone, like other companies
which operate in areas where, due to factors such as geographical conditions or
subscriber density, the cost to provide service is higher than normal, receives
support revenue from federal and state agencies. For the years ended December
31, 1995, 1996 and 1997, and six months ended June 30, 1997 and 1998, support
revenue accounted for, $4.3 million (30.9%), $5.2 million (36.1%), $5.5 million
(35.6%), $2.7 million (35.7%) and $2.4 million (30.9%), respectively, of the
Company's ILEC revenue.
 
    In July 1997 the Oklahoma Telecommunications Act of 1997 (the "Oklahoma
Telecom Act") became effective. The Oklahoma Telecom Act created the Oklahoma
Universal Service Fund ("OUSF") with one of its stated purposes to promote and
ensure the availability of both primary universal services, at rates that are
reasonable and affordable, and special universal services, and to provide for
reasonably comparable services at affordable rates in rural areas as well as in
urban areas. The OUSF has been implemented so that funds can be made available
to eligible local exchange telecommunications service providers. The Company's
local exchange operations have been determined by the OCC to be eligible to
receive both federal universal funds and OUSF funds. The Oklahoma Telecom Act
specifically provides that eligible local exchange telecommunications service
providers are to receive OUSF funding to reimburse them for
 
                                       23
<PAGE>
their reasonable investment and expenses incurred in providing universal
services which are not recovered from the federal universal service fund or any
other state or federal fund, for infrastructure expenditures or costs incurred
in response to facility or service requirements established by governmental
mandate and for other purposes deemed necessary by the OCC to preserve and
advance universal service. The OCC is promulgating rules to implement the
Oklahoma Telecom Act. The interpretation of the Oklahoma Telecom Act and
application of the OCC rules implementing the OUSF could have a material effect
on Company's wireline operations. With respect to federal support revenue, the
FCC has adopted changes that may, over time, reduce or eliminate subsidies to
telephone companies in areas where the cost of connecting and maintaining phone
lines is higher than the norm. Such changes could have a material adverse effect
on the Company's rural local exchange operations.
 
FRAUDULENT CONVEYANCE STATUTES
 
    Various laws enacted for the protection of creditors may apply to the
Company's incurrence of indebtedness and other obligations in connection with
the American Telco Acquisition, including the issuance of the Notes. If a court
were to find in a lawsuit by an unpaid creditor or representative of creditors
of the Company that the Company did not receive fair consideration or reasonably
equivalent value for incurring such indebtedness or obligation and, at the time
of such incurrence, the Company: (i) was insolvent; (ii) was rendered insolvent
by reason of such incurrence; (iii) was engaged in a business or transaction for
which the assets remaining in the Company constituted unreasonably small
capital; or (iv) intended to incur or believed it would incur obligations beyond
its ability to pay such obligations as they mature, such court, subject to
applicable statutes of limitation, could determine to invalidate, in whole or in
part, such indebtedness and obligations as fraudulent conveyances or subordinate
such indebtedness and obligations to existing or future creditors of the
Company.
 
    The measure of insolvency for purposes of the foregoing will vary depending
on the law of the jurisdiction which is being applied. Generally, however, the
Company would be considered insolvent at a particular time if the sum of its
debts was then greater than all of its property at a fair valuation or if the
present fair saleable value of its assets was then less than the amount that
would be required to pay its probable liabilities on its existing debts as they
became absolute and matured. On the basis of its historical financial
information, its recent operating history and other factors, the Company's
management believes that, after giving effect to indebtedness incurred in
connection with the American Telco Acquisition, the Company was not be rendered
insolvent, will have sufficient capital for the business in which it will be
engaged and will be able to pay its debts as they mature; however, management
has not obtained any independent opinion regarding such issues. In addition,
there can be no assurance as to what standard a court would apply in making such
determination. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
LACK OF PUBLIC MARKET FOR THE NOTES; RESTRICTIONS ON TRANSFERABILITY OF OLD
  NOTES
 
    The Notes are a new issue of securities for which there is currently no
active trading market. The Notes may trade at a discount from their initial
offering price depending upon prevailing interest rates, the market for similar
securities, the financial condition and prospects of the Company and other
factors beyond the control of the Company, including general economic
conditions. The Company does not intend to apply for a listing or quotation of
the Notes. Although the Placement Agents have informed the Company that they
currently intend to make a market in the Notes, they are not obligated to do so,
and any such market making may be discontinued at any time without notice.
Accordingly, no assurance can be given as to the development or liquidity of any
trading market for the Notes.
 
    The Old Notes have not been registered under the Securities Act or any state
securities laws and may not be offered or sold, except pursuant to an exemption
from, or in a transaction not subject to, the registration requirements of the
Securities Act and applicable state securities laws, or pursuant to an effective
registration statement. The Company has registered the New Notes under the
Securities Act and is obligated to use its best efforts to complete an exchange
offer for the Old Notes, but no assurance can be
 
                                       24
<PAGE>
given as to the development of or liquidity of the trading market of the Notes
thereafter. See "Description of the Notes--Registration Rights."
 
CONTROL BY DOBSON COMMUNICATIONS CORPORATION
 
    Dobson Communications is the ultimate parent of the Company. Substantially
all of Dobson Communications' outstanding Class A Common Stock is beneficially
owned by Everett R. Dobson, Dobson Communications' Chairman of the Board,
President and Chief Executive Officer, and his affiliates. Certain decisions
concerning the operations and financial structure of the Company may present a
conflict of interest between the holders of the capital stock of Dobson
Communications and the holders of the Notes. For example, if the Company
encounters financial difficulty or is unable to pay its debts as they mature,
the interests of the holders of the capital stock of Dobson Communications might
conflict with those of holders of the Notes. In addition, equity investors may
have an interest in the Company pursuing acquisitions, divestitures, financings
or other transactions that, in their judgment, could enhance their equity
investment in the Company, even though such transactions might involve risk to
the holders of the Notes.
 
FORWARD-LOOKING STATEMENTS
 
    The description of the Company's plans set forth herein, including the
Company's plans and strategies, its anticipation of revenues from designated
markets, the markets for the Company's services and products, planned capital
expenditures and possible regulatory requirements, and other statements which
predict or forecast future events or which are dependent on future events for
their accuracy, are forward-looking statements. These plans involve a number of
risks and uncertainties. Important factors that could cause actual capital
expenditures, or the Company's performance to differ materially from such plans
include, without limitation, the Company's ability to satisfy the financial
covenants of its existing debt instruments and to raise additional capital; the
Company's ability to integrate acquired operations with existing operations, to
manage its rapid growth successfully and to compete effectively in its ILEC,
fiber and ICP businesses against competitors with greater financial, technical,
marketing and other resources; changes in end-user requirements and preferences;
the development of other technologies and products that may gain more commercial
acceptance than those of the Company; the Company's ability to successfully
market its services to current and new customers, interconnect with ILECs,
expand or replace its OSS and other back office systems, provision new
customers, access markets, install facilities, including switching electronics,
and obtain leased trunking capacity, rights-of-way, building access rights and
any required governmental authorizations, franchises and permits, all in a
timely manner, at reasonable costs and on satisfactory terms and conditions; as
well as unexpected regulatory, legislative and judicial developments. No
assurance can be given that the future results will be achieved; actual events
or results may differ materially as a result of risks facing the Company.
Readers are cautioned not to place undue reliance on these forward-looking
statements which speak only as of the date hereof. The Company undertakes no
obligation to update or revise these forward-looking statements to reflect
events or circumstances after the date hereof including, without limitation,

                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
    The Old Notes were sold by the Company on June 12, 1998 to Morgan Stanley &
Co. Incorporated and NationsBanc Montgomery Securities LLC (together, the
"Placement Agents") in reliance on Section 4(2) of the Securities Act. The
Placement Agents offered and sold the Old Notes only (i) to "qualified
institutional buyers" (as defined in Rule 144A) in compliance with Rule 144A and
(ii) outside the United States to persons other than U.S. Persons, which term
includes dealers or other professional fiduciaries in the United States acting
on a discretionary basis for foreign beneficial owners (other than an estate or
trust), in reliance upon Regulation S under the Securities Act.
 
    In connection with the sale of the Old Notes, the Company and the Placement
Agents entered into a Registration Rights Agreement dated as of June 12, 1998,
which required the Company to file with the Commission a registration statement
under the Securities Act with respect to the New Notes and use its best efforts
to cause such registration statement to become effective under the Securities
Act and, upon the effectiveness of that registration statement, to offer to the
holders of the Old Notes the opportunity to exchange their Old Notes for a like
principal amount of New Notes, which will be issued without a restrictive legend
and which may be reoffered and resold by the holder without restrictions or
limitations under the Securities Act. A copy of the Registration Rights
Agreement has been filed as an exhibit to the Registration Statement of which
this Prospectus is a part. The Exchange Offer is being made pursuant to the
Registration Rights Agreement to satisfy the Company's obligations thereunder.
The term "holder" with respect to the Exchange Offer means any person in whose
name Old Notes are registered on the Company's books or any other person who has
obtained a properly completed stock power from the registered holder, or any
person whose Old Notes are held of record by The Depository Trust Company
("DTC") who desires to deliver such Old Notes by book-entry transfer at DTC.
 
    The Company has not requested, and does not intend to request, an
interpretation by the staff of the Commission with respect to whether the New
Notes issued pursuant to the Exchange Offer in exchange for the Old Notes may be
offered for sale, resold or otherwise transferred by any holder without
compliance with the registration and prospectus delivery provisions of the
Securities Act. Based on interpretations by the staff of the Commission set
forth in no-action letters issued to third parties, the Company believes the New
Notes issued pursuant to the Exchange Offer in exchange for Old Notes may be
offered for resale, resold and otherwise transferred by any holder thereof
(other than broker-dealers, as set forth below, and any such holder that is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act) without compliance with the registration and prospectus delivery provisions
of the Securities Act, provided that such New Notes are acquired in the ordinary
course of such holder's business and that such holder has no arrangement or
understanding with any person to participate in the distribution of such New
Notes. Any holder who tenders in the Exchange Offer with the intention to
participate, or for the purpose of participating, in a distribution of the New
Notes or who is an affiliate of the Company may not rely upon such
interpretations by the staff of the Commission and, in the absence of an
exemption therefrom, must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any secondary resale
transaction. Failure to comply with such requirements in such instance may
result in such holder incurring liabilities under the Securities Act for which
the holder is not indemnified by the Company. Each broker-dealer (other than an
affiliate of the Company) that receives New Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus meeting
the requirements of the Securities Act in connection with any resale of such New
Notes. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. The Company has
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."
 
                                       26
<PAGE>
    The Exchange Offer is not being made to, nor will the Company accept
surrenders for exchange from, holders of Old Notes in any jurisdiction in which
this Exchange Offer or the acceptance thereof would not be in compliance with
the securities or blue sky laws of such jurisdiction.
 
    By tendering in the Exchange Offer, each holder of Old Notes will represent
to the Company that, among other things, (i) the New Notes acquired pursuant to
the Exchange Offer are being obtained in the ordinary course of business of the
person receiving such New Notes, whether or not such person is the holder, (ii)
neither the holder of Old Notes nor any such other person has an arrangement or
understanding with any person to participate in the distribution of such New
Notes, (iii) if the holder is not a broker-dealer, or is a broker-dealer but
will not receive New Notes for its own account in exchange for Old Notes,
neither the holder nor any such other person is engaged in or intends to
participate in the distribution of such New Notes, and (iv) neither the holder
nor any such other person is an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act or, if such holder is an "affiliate," that
such holder will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable.
 
    Following the completion of the Exchange Offer, none of the Old Notes will
be entitled to the contingent increase in interest rate applicable to the Old
Notes. Following the consummation of the Exchange Offer, holders of Old Notes
will not have any further registration rights, and the Old Notes will continue
to be subject to certain restrictions on transfer. See "--Consequences of
Failure to Exchange." Accordingly, the liquidity of the market for the Old Notes
could be adversely affected. See "Risk Factors-- Consequences of the Exchange
Offer on Non-Tendering holders of the Old Notes."
 
    Participation in the Exchange Offer is voluntary and holders should
carefully consider whether to accept. Holders of the Old Notes may wish to
consult their own financial advisors and tax advisors with respect to their
particular tax situation in making their own decisions on whether to participate
in the Exchange Offer.
 
TERMS OF THE EXCHANGE OFFER
 
    GENERAL.  Upon the terms and subject to the conditions set forth in this
Prospectus and in the Letter of Transmittal, the Company will accept any and all
Old Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City
time, on the Expiration Date. The Company will issue $1,000 principal amount of
New Notes in exchange for each $1,000 principal amount of Old Notes accepted in
the Exchange Offer. Holders may tender some or all of their Old Notes pursuant
to the Exchange Offer. However, Old Notes may be tendered only in amounts that
are integral multiples of $1,000 principal amount.
 
    The form and terms of the New Notes will be identical in all material
respects to the form and terms of the Old Notes except that the New Notes will
be registered under the Securities Act and, therefore, certificates representing
New Notes will not bear legends restricting the transfer thereof. The New Notes
will evidence the same debt as the Old Notes, will be entitled to the benefits
of the Indenture and will be treated as a single class thereunder with any Old
Notes that remain outstanding. The Exchange Offer is not conditioned upon any
minimum number of Old Notes being tendered for exchange.
 
   
    As of November 6, 1998, $350,000,000 aggregate principal amount of the Old
Notes were outstanding. This Prospectus, together with the Letter of
Transmittal, is being sent to all registered holders.
    
 
    Holders of Old Notes do not have any appraisal or dissenters' rights under
the Oklahoma General Corporation Act or the Indenture 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 Notes which are not tendered for exchange in the
Exchange Offer will remain outstanding and interest thereon will continue to
accrue, but such Old Notes will not be entitled to any rights or benefits under
the Registration Rights Agreement.
 
                                       27
<PAGE>
    The Company will be deemed to have accepted validly tendered Old Notes when,
as and if the Company has given oral or written notice thereof to the Exchange
Agent. The Exchange Agent will act as agent for the tendering holders for the
purposes of receiving the New Notes from the Company. If any tendered Old Notes
are not accepted for exchange because of an invalid tender, the occurrence of
certain other events set forth herein or otherwise, certificates for any such
unaccepted Old Notes will be returned, without expense, to the tendering holder
thereof as promptly as practicable after the Expiration Date.
 
    Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other than certain applicable taxes described below, in connection with the
Exchange Offer. See "--Fees and Expenses."
 
   
    EXPIRATION DATE; EXTENSIONS; AMENDMENTS.  The term "Expiration Date" shall
mean 5:00 p.m., New York City time, on December 10, 1998, unless the Company, in
its sole discretion, extends the Exchange Offer, in which case the term
"Expiration Date" shall mean the latest date and time to which the Exchange
Offer is extended. Although the Company has no current intention to extend the
Exchange Offer, the Company reserves the right to extend the Exchange Offer at
any time and from time to time by giving oral or written notice to the Exchange
Agent and by timely public announcement communicated, unless otherwise required
by applicable law or regulation, by making a release to the Dow Jones News
Service. During any extension of the Exchange Offer, all Old Notes previously
tendered pursuant to the Exchange Offer and not withdrawn will remain subject to
the Exchange Offer. The date of the exchange of the New Notes for Old Notes will
be as soon as practicable following the Expiration Date.
    
 
    The Company reserves the right, in its sole discretion, (i) to delay
accepting any Old Notes, to extend the Exchange Offer or to terminate the
Exchange Offer if any of the conditions set forth below under "--Conditions of
the Exchange Offer" shall not have been satisfied, by giving oral or written
notice of such delay, extension or termination to the Exchange Agent, or (ii) to
amend the terms of the Exchange Offer in any manner. Any such delay in
acceptance, extension, termination or amendment will be followed as promptly as
practicable by oral or written notice thereof to the registered holders. If the
Exchange Offer is amended in any manner determined by the Company to constitute
a material change, the Company will promptly disclose such amendment by means of
a prospectus supplement that will be distributed to the registered holders, and
the Company will extend the Exchange Offer for a period of time, depending upon
the significance of the amendment and the manner of disclosure to the registered
holders, if the Exchange Offer would otherwise expire during such period.
 
    In all cases, issuance of the New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of a properly completed and duly executed Letter of
Transmittal and all other required documents; provided, however, that the
Company reserves the absolute right to waive any conditions of the Exchange
Offer or defects or irregularities in the tender of Old Notes. If any tendered
Old Notes are not accepted for any reason set forth in the terms and conditions
of the Exchange Offer or if Old Notes are submitted for a greater principal
amount than the holder desires to exchange, such unaccepted or non-exchanged Old
Notes or substitute Old Notes evidencing the unaccepted portion, as appropriate,
will be returned without expense to the tendering holder, unless otherwise
provided in the Letter of Transmittal, as promptly as practicable after the
expiration or termination of the Exchange Offer.
 
    INTEREST ON THE NEW NOTES.  Holders of Old Notes that are accepted for
exchange will not receive accrued interest thereon at the time of exchange.
However, each New Note will bear interest from the most recent date to which
interest has been paid on the Old Notes or New Notes, or if no interest has been
paid on the Old Notes or the New Notes, from June 12, 1998.
 
                                       28
<PAGE>
    PROCEDURES FOR TENDERING OLD NOTES.  The tender to the Company of Old Notes
by a holder thereof pursuant to one of the procedures set forth below will
constitute an agreement between such holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal. A holder of the Old Notes may tender such Old Notes by (i) properly
completing and signing a Letter of Transmittal or a facsimile thereof (all
references in this Prospectus to a Letter of Transmittal shall be deemed to
include a facsimile thereof) and delivering the same, together with any
corresponding certificate or certificates representing the Old Notes being
tendered (if in certificated form) and any required signature guarantees, to the
Exchange Agent at its address set forth in the Letter of Transmittal on or prior
to the Expiration Date (or complying with the procedure for book-entry transfer
described below), or (ii) complying with the guaranteed delivery procedures
described below.
 
    If tendered Old Notes are registered in the name of the signer of the Letter
of Transmittal and the New Notes to be issued in exchange therefor are to be
issued (and any untendered Old Notes are to be reissued) in the name of the
registered holder (which term, for the purposes described herein, shall include
any participant in DTC (also referred to as a book-entry facility) whose name
appears on a security listing as the owner of Old Notes), the signature of such
signer need not be guaranteed. In any other case, the tendered Old Notes must be
endorsed or accompanied by written instruments of transfer in form satisfactory
to the Company and duly executed by the registered holder and the signature on
the endorsement or instrument of transfer must be guaranteed by an eligible
guarantor institution which is a member of one of the following recognized
signature guarantee programs (an "Eligible Institution"): (i) The Securities
Transfer Agents Medallion Program (STAMP), (ii) The New York Stock Exchange
Medallion Signature Program (MSF), or (iii) The Stock Exchange Medallion Program
(SEMP). If the New Notes or Old Notes not exchanged are to be delivered to an
address other than that of the registered holder appearing on the note register
for the Old Notes, the signature in the Letter of Transmittal must be guaranteed
by an Eligible Institution.
 
    THE METHOD OF DELIVERY OF OLD NOTES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
HOLDER. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT
TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.
 
    The Company understands that the Exchange Agent has confirmed with DTC that
any financial institution that is a participant in DTC's system may utilize
DTC's Automated Tender Offer Program ("ATOP") to tender Old Notes. The Company
further understands that the Exchange Agent will request, within two business
days after the date the Exchange Offer commences, that DTC establish an account
with respect to the Old Notes for the purpose of facilitating the Exchange
Offer, and any participant may make book-entry delivery of Old Notes by causing
DTC to transfer such Old Notes into the Exchange Agent's account in accordance
with DTC's ATOP procedures for transfer. However, the exchange of the Old Notes
so tendered will only be made after timely confirmation (a "Book-Entry
Confirmation") of such book-entry transfer and timely receipt by the Exchange
Agent of an Agent's Message (as defined in the next sentence), and any other
documents required by the Letter of Transmittal. The term "Agent's Message"
means a message, transmitted by DTC and received by the Exchange Agent and
forming part of Book-Entry Confirmation, which states that DTC has received an
express acknowledgment from a participant tendering Old Notes which are the
subject of such Book-Entry Confirmation and that such 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.
 
                                       29
<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 Notes (or a confirmation of book-entry transfer of such
Old Notes into the Exchange Agent's account at DTC), is received by the Exchange
Agent, or (ii) a Notice of Guaranteed Delivery or letter, telegram or facsimile
transmission to similar effect (as provided below) from an Eligible Institution
is received by the Exchange Agent. Issuances of New Notes in exchange for Old
Notes tendered pursuant to a Notice of Guaranteed Delivery or letter, telegram
or facsimile transmission to similar effect (as provided below) by an Eligible
Institution will be made only against submission of a duly signed Letter of
Transmittal (and any other required documents) and deposit of the tendered Old
Notes.
 
    All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of Old Notes will be
determined by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all tenders not in proper
form or the acceptance for exchange of which may, in the opinion of the
Company's counsel, be unlawful. The Company also reserves the absolute right to
waive any of the conditions of the Exchange Offer or any defect or irregularity
in the tender of any Old Notes. None of the Company, the Exchange Agent or any
other person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification. Any Old Notes received by the Exchange Agent that are not validly
tendered and as to which the defects or irregularities have not been cured or
waived, or if Old Notes are submitted in principal amount greater than the
principal amount of Old Notes being tendered by such tendering holder, such
unaccepted or non-exchanged Old Notes will be returned by the Exchange Agent to
the tendering holder, unless otherwise provided in the Letter of Transmittal, as
soon as practicable following the Expiration Date.
 
    In addition, the Company reserves the right in its sole discretion (a) to
purchase or make offers for any Old Notes that remain outstanding subsequent to
the Expiration Date, and (b) to the extent permitted by applicable law, to
purchase Old Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers will differ from the terms
of the Exchange Offer.
 
    GUARANTEED DELIVERY PROCEDURES.  If the holder desires to accept the
Exchange Offer and time will not permit a Letter of Transmittal or Old Notes to
reach the Exchange Agent before the Expiration Date or the procedure for
book-entry transfer cannot be completed on a timely basis, a tender may be
effected if the Exchange Agent has received at its office, on or prior to the
Expiration Date, a letter, telegram or facsimile transmission from an Eligible
Institution setting forth the name and address of the tendering holder, the
name(s) in which the Old Notes are registered and the certificate number(s) of
the Old Notes to be tendered, and stating that the tender is being made thereby
and guaranteeing that, within three New York Stock Exchange trading days after
the date of execution of such letter, telegram or facsimile transmission by the
Eligible Institution, such Old Notes, in proper form for transfer (or a
confirmation of book-entry transfer of such Old Notes into the Exchange Agent's
account at DTC), will be delivered by such Eligible Institution together with a
properly completed and duly executed Letter of Transmittal (and any other
required documents). Unless Old Notes being tendered by the above-described
method are deposited with the Exchange Agent within the time period set forth
above (accompanied or preceded by a properly competed Letter of Transmittal and
any other required documents), the Company may, at its option, reject the
tender. Copies of a Notice of Guaranteed Delivery which may be used by Eligible
Institutions for the purposes described in this paragraph are available from the
Exchange Agent.
 
    TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL.  The Letter of
Transmittal contains, among other things, the following terms and conditions,
which are part of the Exchange Offer.
 
    The party tendering Old Notes for exchange (the "Transferor") exchanges,
assigns and transfers the Old Notes to the Company and irrevocably constitutes
and appoints the Exchange Agent as the Transferor's agent and attorney-in-fact
to cause the Old Notes to be assigned, transferred and exchanged. The Transferor
represents and warrants that it has full power and authority to tender,
exchange, assign and
 
                                       30
<PAGE>
transfer the Old Notes and to acquire New Notes issuable upon the exchange of
such tendered Old Notes, and that, when the same are accepted for exchange, the
Company will acquire good and unencumbered title to the tendered Old Notes, free
and clear of all liens, restrictions, charges and encumbrances and not subject
to any adverse claim. The Transferor also warrants that it will, upon request,
execute and deliver any additional documents deemed by the Company to be
necessary or desirable to complete the exchange, assignment and transfer of
tendered Old Notes or to transfer ownership of such Old Notes on the account
books maintained by DTC. All authority conferred by the Transferor will survive
the death, bankruptcy or incapacity of the Transferor and every obligation of
the Transferor shall be binding upon the heirs, personal representatives,
executors, administrators, successors, assigns, trustees in bankruptcy and other
legal representatives of such Transferor.
 
    By executing a Letter of Transmittal, each holder will make to the Company
the representations set forth above under the heading "--Purpose and Effect of
the Exchange Offer."
 
    WITHDRAWAL OF TENDERS OF OLD NOTES.  Except as otherwise provided herein,
tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York
City time, on the Expiration Date.
 
    To withdraw a tender of Old Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to 5:00 p.m., New York City time, on
the Expiration Date. Any such notice of withdrawal must (i) specify the name of
the person having deposited the Old Notes to be withdrawn (the "Depositor"),
(ii) identify the Old Notes to be withdrawn (including the certificate number or
numbers and principal amount of such Old Notes), (iii) contain a statement that
such holder is withdrawing its election to have such Old Notes exchanged, (iv)
be signed by the holder in the same manner as the original signature on the
Letter of Transmittal by which such Old Notes were tendered (including any
required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the Old Notes register the
transfer of such Old Notes in the name of the person withdrawing the tender, and
(v) specify the name in which any such Old Notes are to be registered, if
different from that of the Depositor. If Old Notes have been tendered pursuant
to the procedure for book-entry transfer, any notice of withdrawal must specify
the name and number of the account at the book-entry transfer facility. All
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by the Company, whose determination shall be
final and binding on all parties. Any Old Notes so withdrawn will be deemed not
to have been validly tendered for purposes of the Exchange Offer and no New
Notes will be issued with respect thereto unless the Old Notes so withdrawn are
validly retendered. Any Old Notes which have been tendered but which are not
accepted for exchange will be returned to the holder thereof without cost to
such holder as soon as practicable after withdrawal, rejection of tender or
termination of the Exchange Offer. Properly withdrawn Old Notes may be
retendered by following one of the procedures described above under
"--Procedures for Tendering Old Notes" at any time prior to the Expiration Date.
 
CONDITIONS OF THE EXCHANGE OFFER
 
    Notwithstanding any other term of the Exchange Offer, or any extension of
the Exchange Offer, the Company shall not be required to accept for exchange, or
exchange New Notes for, any Old Notes, and may terminate the Exchange Offer as
provided herein on or before the Expiration Date, if:
 
        (a) any statute, rule or regulation shall have been enacted, or any
    action shall have been taken by any court or governmental authority which,
    in the reasonable judgment of the Company, would prohibit, restrict or
    otherwise render illegal consummation of the Exchange Offer; or
 
        (b) any change, or any development involving a prospective change, in
    the business or financial affairs of the Company or any of its subsidiaries
    has occurred which, in the reasonable judgment of the Company, might
    materially impair the ability of the Company to proceed with the Exchange
    Offer or materially impair the contemplated benefits of the Exchange Offer
    to the Company; or
 
                                       31
<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
 
and the Company does not wave such event or change.
 
    If the Company determines in its sole discretion that any of the above
conditions have not been satisfied on or prior to the Expiration Date, the
Company may (i) refuse to accept any Old Notes and return all tendered Old Notes
to the tendering holders, (ii) extend the Exchange Offer and retain all Old
Notes tendered prior to the Expiration Date, subject, however, to the right of
holders to withdraw such Old Notes (see "--Terms of the Exchange
Offer--Withdrawal of Tenders of Old Notes"), or (iii) waive such unsatisfied
conditions with respect to the Exchange Offer and accept all validly tendered
Old Notes which have not been withdrawn. If such waiver constitutes a material
change to the Exchange Offer, the Company will promptly disclose such waiver by
means of a prospectus supplement that will be distributed to the registered
holders, and the Company will extend the Exchange Offer for a period of time,
depending upon the significance of the waiver and the manner of disclosure to
the registered holders, if the Exchange Offer would otherwise expire during such
period.

FEES AND EXPENSES
 
    The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telecopy, telephone or in person by officers and regular
employees of the Company and its affiliates. No additional compensation will be
paid to any such officers and employees who engage in soliciting tenders.
 
    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
 
                                       32
<PAGE>
out-of-pocket expenses incurred by them in forwarding copies of this Prospectus,
the Letter of Transmittal and related documents to the beneficial owners of the
Old Notes and in handling or forwarding tenders for exchange.
 
    The expenses to be incurred in connection with the Exchange Offer will be
paid by the Company. Such expenses include fees and expenses of the Exchange
Agent and transfer agent and registrar, accounting and legal fees and printing
costs, among others.
 
    The Company will pay all transfer taxes, if any, applicable to the exchange
of the Old Notes pursuant to the Exchange Offer. If, however, New Notes, or Old
Notes for principal amounts not tendered or accepted for exchange, are to be
delivered to, or are to be issued in the name of, any person other than the
registered holder of the Old Notes tendered or if a transfer tax is imposed for
any reason other than the exchange of the Old Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
    The Old Notes that are not exchanged for New Notes pursuant to the Exchange
Offer will remain restricted securities within the meaning of Rule 144 of the
Securities Act. Accordingly, such Old Notes may be resold only (i) to the
Company or any subsidiary thereof, (ii) to a qualified institutional buyer in
compliance with Rule 144A, (iii) to an institutional accredited investor that,
prior to such transfer, furnishes to the Trustee a signed letter containing
certain representations and agreements relating to the restrictions on transfer
of the Old Notes (the form of which letter can be obtained from the Trustee)
and, if such transfer is in respect of an aggregate principal amount of Old
Notes at the time of transfer of less than $100,000, an opinion of counsel
acceptable to the Company that such transfer is in compliance with the
Securities Act, (iv) outside the United States in compliance with Rule 904 under
the Securities Act, (v) pursuant to the exemption from registration provided by
Section 4(2) of under the Securities Act, and Rule 144 adopted thereunder (if
available), or (vi) pursuant to an effective registration statement under the
Securities Act. The liquidity of the Old Notes could be adversely affected by
the Exchange Offer. Following the consummation of the Exchange Offer, holders of
the Senior Preferred Stock will have no further registration rights under the
Registration Rights Agreement and will not be entitled to the contingent
increase in the dividend rate applicable to the Old Notes.

    SELECTED HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL AND OTHER DATA
 
    The following table sets forth certain historical consolidated financial
data for Logix. The selected consolidated financial data as of and for the years
ended December 31, 1993, 1994, 1995, 1996 and 1997 were derived from the
Company's audited consolidated financial statements which have been audited by
Arthur Andersen LLP, independent public accountants. The selected consolidated
financial data as of and for the six months ended June 30, 1997 and 1998 were
derived from unaudited consolidated financial statements, 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 (consisting only
of normal recurring adjustments) necessary for a fair presentation of the
Company's result of operations and financial position for such periods and as of
such dates. Operating results for the six months ended June 30, 1998 are not
necessarily indicative of results that may be expected for the full year. The
pro forma consolidated statements of operations data give effect to the American
Telco Acquisition and the offering of the Old Notes as if they occurred on
January 1, 1997 and the pro forma consolidated balance sheet data give effect to
the American Telco Acquisition and the offering of the Old Notes as if they
occured on June 30, 1998. The unaudited selected pro forma consolidated
financial data are based on currently available information and certain
assumptions that management believes are reasonable. The pro forma consolidated
financial information does note purport to represent what the Company's results
of operations would have been if the American Telco acquisition and the offering
of the Old Notes had been completed on such dates, nor does it purport to
indicate the future financial position or results of future operations of the
Company. The information set forth below financial 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 financial statements and the related notes thereto
included elsewhere in this Prospectus.

- ------------------------
 
(1) Extraordinary items reflect expense associated with early extinguishment of
    debt, net of income tax benefit.
 
(2) Cumulative effect of change in accounting principle reflects the charge
    taken, net of income tax benefit, as a result of the implementation of AICPA
    Statement of Position 98-5 "Reporting on the Costs of Start-up Activities,"
    effective January 1, 1998, and the benefit, net of income tax expense, from
    implementation of Statement of Financial Accounting Standards No. 109
    "Accounting for Income Taxes," in 1993.
 
(3) ICP revenue includes network management services provided to affiliates of
    Logix. For 1994, 1995 and 1996 and the six months ended June, 1997, network
    management services account for all of the ICP revenue and for 1997 and the
    six months ended June 30, 1998, for $124,000 and $35,200 of ICP revenue,
    respectively.
 
   
(4) Adjusted EBITDA represents earnings before interest expense, income taxes,
    depreciation and amortization, other income, extraordinary items, and
    changes in accounting principles. Adjusted EBITDA is provided because it is
    a measure commonly used in the industry and by the Company to assess a
    company's operating performance and its ability to incur or service debt. In
    addition, the Indenture governing the Notes contains certain covenant
    requirements that are based on Adjusted EBITDA. See "Description of the
    Notes-- Covenants." Adjusted EBITDA is not derived pursuant to generally
    accepted accounting principles and should not be construed as an alternative
    to net income, as a measure of performance, or to cash flows, as a measure
    of liquidity. Adjusted EBITDA, as measured by the Company, may differ
    significantly from similarly named measurements of other companies and, as a
    consequence, may not provide any degree of reliable comparability. The
    calculation of Adjusted EBITDA does not include the Company's commitments
    for capital expenditures or payments of debts and should not be deemed to
    represent funds available to the Company.
    
 
(5) For the year ended December 31, 1994 and six months ended June 30, 1998,
    earnings were insufficient to cover fixed charges by $.2 million and $5.8
    million, respectively. On a pro forma basis for the year ended December 31,
    1997, and the six months ended June 30, 1998, earnings would have been
    insufficient to cover fixed charges by $51.2 million and $27.7 million,
    respectively. "Earnings" is defined as earnings before extraordinary items,
    accounting changes and fixed charges. Fixed charges consist of interest
    expense, amortization of deferred financing costs, income taxes and a
    portion of rent expense under operating leases representative of interest.
 
(6) Route miles refers to the number of miles over which fiber optic cables are
    installed.
 
(7) Fiber miles refers to the number of route miles multiplied by the number of
    fibers installed along that path.

                PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA
 
    The following unaudited pro forma condensed consolidated statements of
operations have been prepared to give effect to the American Telco Acquisition
and the Offering. The accompanying unaudited pro forma condensed consolidated
statements of operations of the Company for the year ended December 31, 1997 and
for the six months ended June 30, 1998 give effect to the American Telco
Acquisition and the Offering as if they occurred on January 1, 1997. The
American Telco Acquisition and the Offering occurred in the second quarter of
1998, and thus are reflected in the historical June 30, 1998 balance sheet. The
American Telco Acquisition has been accounted for using the purchase method of
accounting.
 
    The unaudited pro forma condensed consolidated statements of operations have
been prepared on the basis of certain assumptions that Logix believes are
reasonable. Management of the Company believes there will be no variations from
the information and assumptions applied which will have a material effect on the
pro forma financial statements presented, based on estimates of fair value using
available information provided by the management of American Telco.
 
    The unaudited pro forma condensed consolidated statements of of operations
and notes thereto are provided for informational purposes only and do not

(1) To reflect the results of operations for American Telco from January 1, 1998
    to the date of closing.
 
(2) To reflect the adjustment to depreciation and amortization resulting from
    the allocation of the purchase price to the fixed and intangible assets of
    American Telco. The amount of historical depreciation and amortization for
    American Telco was $1.3 million. The amount of depreciation and amortization
    resulting from the allocation of purchase price is $5.7 million, which
    increase is primarily the result of the amortization of goodwill. American
    Telco had historically depreciated fixed assets over periods from one to
    seven years. The Company has assessed the remaining useful lives of the
    fixed assets acquired from American Telco and will utilize lives similar to
    those utilized by American Telco. Goodwill will be amortized over a 15 year
    period.
 
(3) To reflect (i) the elimination of $.1 million of interest expense associated
    with indebtedness of American Telco, which was repaid by the sellers of
    American Telco upon consummation of the American Telco Acquisition, (ii)
    $19.7 million of interest expense relating to the Notes and (iii) $.6
    million of amortization expense relating to amortization of the deferred
    financing costs incurred in connection with the Offering.
 
(4) To reflect an adjustment to income tax expense for effects of the American
    Telco Acquisition. Net operating loss carryforwards generated have been
    recognized as an income tax benefit, assuming a 38% statutory tax rate.
    Recognition of tax benefit has been limited to the extent that the Company
    had a previously recorded deferred tax liability since it is more likely
    than not that any excess tax benefit would not be recognized. For the six
    months ended June 30, 1998, no benefit is recognized, as the previously
    recorded deferred tax liability is assumed to be fully utilized in 1997.

(1) To reflect the adjustment to depreciation and amortization resulting from
    the allocation of the purchase price to the fixed and intangible assets of
    American Telco. The amount of historical depreciation and amortization for
    American Telco was $2.6 million. The amount of depreciation and amortization
    resulting from the allocation of purchase price is $12.3 million, which
    increase is primarily the result of the amortization of goodwill. American
    Telco had historically depreciated fixed assets over periods from one to
    seven years. The Company has assessed the remaining useful lives of the
    fixed assets acquired from American Telco and will utilize lives similar to
    those utilized by American Telco. Goodwill will be amortized over a 15 year
    period.
 
(2) To reflect (i) the elimination of $.2 million of interest expense associated
    with indebtedness of American Telco, which was repaid by the sellers of
    American Telco upon consummation of the American Telco Acquisition, (ii)
    $42.9 million of interest expense relating to the Notes, and (iii) $1.2
    million of amortization expense relating to amortization of the deferred
    financing costs incurred in connection with the Offering.
 
(3) To reflect an adjustment to income tax expense for effects of the American
    Telco Acquisition. Net operating loss carryforwards generated have been
    recognized as an income tax benefit, assuming a 38% statutory tax rate.
    Recognition of tax benefit has been limited to the extent that the Company
    had a previously recorded deferred tax liability since it is more likely
    than not that any excess tax benefit would not be recognized.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
    Logix seeks to be the leading provider of integrated local, long distance,
data and other telecommunications services to small and medium-sized business
customers throughout the Southwest United States. Since 1936, the Company,
through its predecessor and subsidiaries, has provided ILEC services in Oklahoma
through its subsidiary Dobson Telephone Company. In addition, the Company
operates long-haul fiber optic facilities in Oklahoma, Texas and Colorado. In
1997, the Company began offering facilities-based ICP services in Oklahoma under
its LOGIX-TM- brand name, and commenced offering these services in several
markets in Texas in 1998. In June, 1998 the Company consummated its purchase of
American Telco, a Texas-based ICP with operations in Houston, Dallas, Fort
Worth, San Antonio and Austin.
 
REVENUE
 
LOGIX
 
    ILEC OPERATIONS.  The Company's predecessors began providing ILEC services
in 1936, and the Company currently owns and operates nine contiguous exchanges
in western Oklahoma and three contiguous exchanges adjacent to and east of the
Oklahoma City metropolitan area. Logix's local exchange revenues consist of (i)
end user revenue, which includes charges for local service and enhanced services
such as call waiting and call forwarding; (ii) access revenue, which is paid by
IXCs for providing access from the IXCs point of presence to the end user who
makes or receives a long distance call; and (iii) support revenue, which is paid
by federal and state agencies to companies, such as Logix, which operate in
areas where, due to factors such as geographic conditions or subscriber density,
the cost to provide service is higher than normal. As of December 31, 1995, 1996
and 1997 and June 30, 1997 and 1998, the ILEC operations served 11,806, 11,959,
12,633, 12,446 and 12,932 access lines, respectively.
 
    Support revenue, which consists of high cost funds ("HCF") from state
agencies and universal service funds ("USF") from federal and state agencies,
accounted for approximately 30.9%, 36.1%, 35.6%, 35.7% and 30.9% of Logix's
revenue from its ILEC operations, or $4.3 million, $5.2 million, $5.5 million,
$2.7 million and $2.4 million, for the years ended December 31, 1995, 1996 and
1997 and the six months ended June 30, 1997 and 1998, respectively.
 
    The Telecommunications Act potentially impacts the Company's sources of
support revenue. Under previous regulation, access charges contained implicit
support for high cost areas. Regulations adopted pursuant to the
Telecommunications Act would remove implicit support from access charges and
place more emphasis for such support on HCF/USF. In May 1997, the FCC adopted
changes that may, over time, reduce or eliminate subsidies to telephone
companies in areas where the cost of connecting and maintaining phone lines is
demonstrated to be above the industry or area norm. The Company will continue to
pursue its strategy to lessen the impact of any future regulatory changes by
reducing its operating costs through consolidation of operational functions at
the Company level in order to achieve economies of scale. See "Risk
Factors--Regulation."
 
    FIBER OPERATIONS.  Logix's revenues from its fiber services are generated
from three different sources of long-haul transport services: (1) as a
"carrier's carrier," (2) to private businesses and government agencies requiring
network services, and (3) for Dobson Communications' other subsidiaries. For the
year ended December 31, 1997 and the six months ended June 30, 1998,
approximately 41% and 46%, respectively, of Logix's gross fiber revenue was
attributable to NTS Communication, Inc. and Vyvx, Inc. and approximately 25% and
30%, respectively, of its fiber revenue was attributable to Dobson
Communications' other subsidiaries. The total number of DS3 equivalent fiber
lines leased as of December 31, 1995, 1996, and 1997 and as of June 30, 1997 and
1998 were 20, 46, 53, 48, and 73, respectively.
 
                                       42
<PAGE>
    Although the Company currently has excess capacity and does not currently
plan to add more fiber optic lines, the Company will seek to expand its network
through interconnect agreements to access other major population centers
(including routes which may be attractive to major carriers). The Company
believes that the pricing of fiber will remain relatively constant in the near
future. While the pricing of the Company's fiber services has remained
relatively constant, the Company is entering into more long term contracts which
give discounts to the customer and the Company may be required to give discounts
to high volume customers.
 
    ICP OPERATIONS.  The Company began offering facilities-based ICP services in
October 1997 and currently provides these services to customers in several major
markets in Oklahoma and Texas. ICP revenue includes network management services
provided to Company affiliates. For 1995 and 1996 and the six months ended June
30, 1997 network management services accounted for all ICP revenue and for 1997
and the six months ended June 30, 1998, for $124,000 and $35,200, respectively.
The Company's ICP services include local exchange, long distance, enhanced data,
Internet, intranet and extranet services, private line and integration services.
As of June 30, 1998, the Company's ICP operations served 22,735 access lines
(including those acquired in the American Telco Acquisition). The Company
typically obtains a one-year contract with minimum monthly usage from its
business ICP customers.
 
    On June 15, 1998, the Company purchased the outstanding common stock of
American Telco for $131.5 million. American Telco is based in Houston, Texas and
operates in five major Texas markets: Houston, Dallas, Fort Worth, San Antonio
and Austin. In addition, on June 22, 1998, Logix purchased certain long distance
customers and related assets of Zenex for approximately $4.7 million.
 
    Dobson Wireline incurred operating losses and negative cash flows from
operations and EBITDA related to its ICP services in 1997 and the six months
ended June 30, 1998. Such negative cash flows from operations and EBITDA are
expected to continue until Logix develops and expands its ICP operations and
subscriber base. These losses were primarily a result of selling, general and
administrative ("SG&A") expenses. As a result of the continued expansion of its
ICP operations the Company will continue to incur significant increases in
expenses associated with these activities. Also, the Company expects that the
addition of ICP services will have an adverse impact on its combined gross
margins, because the gross margins on the ICP services are expected to be lower
than the gross margins on its ILEC and fiber operations.
 
    The Company offers ICP services at prices that are competitive to the ILECs.
The Company believes that while pricing is an important element in the marketing
of their services, small and medium-sized businesses are also focused on the
benefits from customer care, bundled telecommunications services with one point
of contact for sales and service, and consistent quality of service when making
their purchase decisions.
 
    During the past several years the market prices for many telecommunications
services have been declining. The Company believes that this trend is likely to
continue and will have a negative effect on the Company's gross margins that may
not be offset completely by savings from the decrease in the Company's cost of
service.
 
    Current industry statistics demonstrate that there is a significant churn
for customers within the industry. The Company believes that the churn is
especially high when customers are buying resold services or only long distance
services. The Company believes that by offering an integrated package of
telecommunications services, and by providing superior customer care, it will be
able to minimize customer churn.
 
AMERICAN TELCO
 
    American Telco derived most of its revenue from the sale of long distance
service to small and medium-sized businesses and residential customers in Texas.
American Telco launched the sale of local service in March 1997, but only on a
limited basis until August 1997, while developing its back office
 
                                       43
<PAGE>
systems and infrastructure to support local service. As of March 31, 1998,
American Telco had approximately 16,400 business customers and approximately
6,000 residential customers and served 13,410 local access lines. Business
customers represented approximately 95% of revenues for the year ended December
31, 1997 and six months ended June 30, 1998. The business customers are
diversified and no one customer accounted for more than .7% of total revenues
and substantially all of American Telco's revenue is derived from providing long
distance services. In addition, the Company believes that American Telco's
average revenue per minute of use will continue to decline as the Company adds a
higher proportion of business customers who generally have a higher volume of
usage and are therefore charged lower rates per minute than residential
customers. American Telco's customer base has been shifting as American Telco
has deemphasized its residential services.
 
    American Telco's contracts for long distance services generally provide for
payment in arrears based on minutes of use. American Telco offers flat rate
plans with incentives for customers who commit to a term of one or two years.
Discounts are provided to customers based on the volume of usage.
 
COST AND EXPENSES
 
    The Company's primary expense categories include cost of service, SG&A, and
depreciation and amortization.
 
    Cost of service for Logix's ILEC and fiber operations consists primarily of
costs associated with operating and maintaining the Company's facilities and for
the fiber operations, costs associated with leasing lines from third party
providers.
 
    Cost of service for the ICP operations (including American Telco's) consists
of fixed costs for leased lines, the variable costs of origination, termination
and access services provided through ILECs and other telecommunications
companies, and internal costs associated with operating and maintaining the
Company's facilities. The Company intends to deploy digital switching platforms
with local and long distance capability and initially lease fiber trunking
capacity from ILECs and CLECs to connect the Company's switches with its
transmission equipment collocated in ILEC central offices. The Company will
lease unbundled loop and high capacity digital lines from the ILECs to connect
its customers and other carriers' networks to the Company's network. These
charges vary by ILEC and are regulated by state authorities pursuant to the
Telecommunications Act. ILECs typically charge both a startup fee as well as a
monthly recurring fee for use of their central offices for collocation. The
Company will use its own fiber network, where available, to carry long distance
traffic and will also enter into resale agreements with long distance carriers
for transmission services. Such agreements typically provide for the resale of
long distance services on a per-minute basis and may contain minimum volume
commitments. The Company may be obligated to pay underutilization charges in the
event it over-estimates its requirements; however, in the event it
underestimates its need for transmission capacity, the Company may be required
to obtain capacity through more expensive means. Also, the Company will need to
increase the capacity of its switches and add additional ANP devices and
switches as market demand warrants.
 
    SG&A includes all infrastructure costs such as selling, customer support,
corporate administration, personnel, and network maintenance. Selling expenses
include commissions for the Company's sales program. Commissions are paid to
direct sales persons for new business generated with additional incentives for
multiple service offerings and long-term contracts. Independent sales agents
receive commissions for generating new sales and ongoing sales to existing
customers. As the Company's customer base grows, and as the Company continues to
expand into new geographic markets, adds new sales offices and facilities and
enlarges its current product offerings, the cost of services and SG&A are
expected to increase substantially.
 
    Depreciation and amortization relates primarily to switching equipment,
facilities, computers and software, and is expected to increase as the Company
incurs significant capital expenditures to install
 
                                       44
<PAGE>
additional switches. Depreciation and amortization will include amortization of
goodwill acquired in the American Telco Acquisition.

million, or 8.4%, to $2.4 million in the six months ended June 30, 1998 from
$2.2 million in the first six months of 1997 due primarily to increased revenue
from new customers.
 
    ICP.  ICP revenue increased $4.3 million to $4.4 million for the six months
ended June 30, 1998 from $.1 million for the six months ended June 30, 1997. ICP
revenue in the first six months of 1998 consists primarily of charges for local
and long-distance service and equipment sales. ICP revenue includes network
management services provided to Company affiliates. For the six months ended

                                       45
<PAGE>
six months ended June 30, 1998 as a result of increased maintenance costs of
plant and costs associated with customer growth.
 
    FIBER.  Cost of fiber service increased $.3 million, or 121.1%, to $.6
million in the first six months of 1998 from $.3 million in the first six months
of 1997. The increase was primarily the result of service provided by certain
third party carriers incurred as a result of the addition of new customers.
 
    ICP.  Cost of ICP service increased $4.6 million to $4.7 million for the six
months ended June 30, 1998 from $.1 million for the first six months of 1997.
These costs primarily consisted of costs associated with the operations and
maintenance of Company facilities and wholesale charges from third party service
providers. Included in ICP cost of service for the six months ended June 30,
1998 is $.1 million of costs related to network management services provided to
affiliates of Dobson Communications.
 
    SELLING, GENERAL AND ADMINISTRATIVE.  For the six months ended June 30,
1998, SG&A costs increased $4.9 million, or 127.1%, to $8.7 million compared to
$3.8 million in the first six months of 1997. The increase was primarily due to
increased salary costs resulting from additional sales, administrative and
marketing personnel in the Company's ICP operations.
 
    DEPRECIATION AND AMORTIZATION EXPENSE.  For the six months ended June 30,
1998, depreciation and amortization expense increased $.8 million, or 33.4%, to
$3.1 million from $2.3 million in the first six months of 1997. The ILEC and
Fiber segments' depreciation and amortization expense remained consistent
between periods at $1.6 million and $.7 million, respectively. The ICP segment's
depreciation and amortization expense increased $.9 million, to $.9 million for
the six months ended June 30, 1998. This increase is primarily a result of
depreciation and amortization on assets purchase for its recently launched Logix
business and assets acquired in the American Telco Acquisition.
 
    OPERATING INCOME (LOSS).  As a result of the items discussed above,
operating income for the six months ended June 30, 1998, decreased $6.0 million
to a loss of $3.5 million from an income of $2.5 million in the first six months
of 1997.
 
    INTEREST EXPENSE.  Net interest expense for the six months ended June 30,
1998 increased $1.2 million, or 95.4%, to $2.4 million from $1.2 million for the
first six months of 1997. The ILEC segment's net interest expense decreased $.2
million, or 18.9%, to $.5 million in the first six months of 1998 from $.7
million in the first six months of 1997. The decrease is primarily the result of
paying off individual mortgage notes with higher interest rates. The Fiber
segment's net interest expense decreased $.6 million, or 100.0%, in the first
six months of 1998 from $.6 million in the first six months of 1997. The
decrease is a result of the December 31, 1997 Dobson Communications capital
contribution to the Company, which relieved the Fiber segment's outstanding
portion of the revolving credit facility and related interest expense payable to
Dobson Communications. The ICP segment's net interest expense increased $1.9
million, or 100.0%, to $1.9 million in the first six months of 1998. Of the
increase, $2.2 million related to increased interest expense as a result of the
issuance of the Notes in June, 1998. The increase in interest expense was offset
by $.3 million of interest income earned on the funds held in escrow and cash on
hand from the issuance of the Notes.
 
    OTHER INCOME.  For the six months ended June 30, 1998, total other income
(consisting of equity in income of unconsolidated partnership and other income
(expense)) remained consistent at $.1 million compared to the first six months
of 1997.
 
    INCOME BEFORE INCOME TAXES AND EXTRAORDINARY ITEMS.  As a result of the
items discussed above, income before income taxes and extraordinary items for
the six months ended June 30, 1998, income before income taxes and extraordinary

    ILEC.  Income before income taxes and extraordinary items from the Company's
ILEC operations increased $1.0 million to $2.2 million for the first six months
of 1998 from $1.2 million in the first six months of 1997. This is primarily due
to decreased SG&A costs applicable to the ILEC business, as a result of
increased management focus on the ICP operations.
 
    FIBER.  Income before income taxes and extraordinary items from the
Company's fiber operations increased $.5 million to $.8 million for the first
six months of 1998 from $.3 million in the first six months of 1997. This is
primarily due to a decrease in interest expense in 1988, as a result of the
extinguishment of debt on December 31, 1997.
 
    ICP.  Income before income taxes and extraordinary items from the Company's
ICP operations decreased $8.9 million to a loss of $8.8 million for the first
six months of 1998 from a loss of $.2 million in the first six months of 1997.
This is a result of increased SG&A from the start up of the ICP operations and
increased depreciation and interest expense from the American Telco Acquisition.
 
    EXTRAORDINARY EXPENSE.  Extraordinary expense in the first six months of
1997 of $.2 million is due to the write-off of deferred debt costs associated
with the the Company's fiber operations.
 
    CUMULATIVE EFFECT OF CHANGE IN ACCOUNTING PRINCIPLE.  Cumulative effect of
change in accounting principle in the six months ended June 30, 1998 reflects
the charge taken as a result of implementation of AICPA Statement of Position
98-5 "Reporting on the Costs of Start-up Activities" on January 1, 1998.

    ILEC.  ILEC revenue increased $1.0 million, or 6.9%, to $15.4 million for
1997 compared to $14.4 million for 1996 due primarily to a $.3 million increase
in support revenue, an increase in toll charges and an increase in the number of
access lines from 11,959 as of December 31, 1996 to 12,633 as of December 31,
1997.
 
    FIBER.  The Company's revenue from its fiber operations increased $1.2
million, or 33.8%, to $4.6 million in 1997 from $3.4 million in 1996 due

of 53 DS3s compared to 46 at December 31, 1996.
 
    ICP.  The Company launched its LOGIX operations in October 1997, generating
$.1 million of service revenue primarily related to equipment, local and long
distance sales. The remaining $.1 million in ICP revenue in 1997, relates to
network management services provided to affiliates of Dobson Communications.

result of fixed asset additions. The ICP segment's depreciation and amortization
expense increased $.2 million, to $.2 million as of December 31, 1997. This
increase was primarily a result of depreciation and amortization on assets
purchased for its recently launched Logix business.

    ILEC.  ILEC revenue increased $.7 million, or 4.9%, to $14.4 million for the
year ended December 31, 1996 from $13.7 million in 1995. The increase is
primarily due to reimbursement received from a new state fund created in 1996
designed to provide additional support revenue to high cost providers of local
telephone service.
 
    FIBER.  The Company's revenue from its fiber operations increased $.9
million, or 37.2%, to $3.4 million in 1996 from $2.5 million in 1995 primarily
as a result of additional revenue of $.8 million from an existing customer in

    ILEC.  Cost of ILEC service increased $.2 million, or 8.5%, to $1.9 million
in 1996 from $1.7 million in 1995. Cost of ILEC service in 1996 increased as a
percentage of ILEC revenue to 13.1% from 12.6% in 1995 as a result of increased
maintenance costs of plant and costs associated with customer growth.
 
    FIBER.  Cost of fiber service increased $.2 million, or 36.8%, to $.6
million in 1996, from $.4 million in 1995. The increase was the result of
increased costs for technical personnel for maintenance and operations of
Company facilities.
 
    ICP.  Cost of ICP service increased $.1 million, or 15.3%, to $.4 million in
1996 from $.3 million in 1995. The increase is primarily related to increased
personnel costs related to network management services.

SG&A costs increased $1.3 million, or 19.7%, to $7.8 million in 1996 from $6.5
million in 1995. As a percentage of total revenue, SG&A costs increased to 43.6%
in 1996 from 40.2% in 1995. The increase was primarily due to increased
personnel charges attributable to increased sales and administrative staff, as
well as additional corporate overhead expenses.
 
    DEPRECIATION AND AMORTIZATION EXPENSE.  For the year ended December 31,
1996, depreciation and amortization expense increased $.4 million, or 8.6%, to
$4.5 million compared to $4.1 million in 1995. The ILEC segment's depreciation
and amortization expense remained consistent between periods at $3.2 million.
The Fiber segment's depreciation and amortization expense increased $.3 million,
or 31.0%, to $1.2 million in 1996 compared to $.9 million in 1995. The increase
was primarily due to fixed asset additions. The ICP segment incurred minimal
amounts of depreciation and amortization expense in 1996 and 1995.
 
    OPERATING INCOME (LOSS).  As a result of the items discussed above,
operating income for the year ended December 31, 1996, decreased $.3 million to

    INTEREST EXPENSE.  Net interest expense for the year ended December 31, 1996
increased $.2 million, or 11.1%, to $2.2 million from $2.0 million for 1995. The
ILEC segment's net interest expense remained consistent between periods at $1.3
million. The Fiber segment's net interest expense increased $.3 million, or
40.4%, to $.9 million in 1996 from $.6 million in 1995. The increase was a
result of the increased outstanding portion of the revolving credit facility and
related interest expense payable to Dobson Communications. The ICP segment's did
not incur any net interest expense in 1996 or 1995.
 
    OTHER EXPENSE.  For the year ended December 31, 1996, total other expense
(consisting of equity in income (loss) of unconsolidated partnership and other
income (expense)) was $.1 million compared to $.3 million in 1995. The change
was primarily due to the unconsolidated subsidiary generating decreased losses
in 1996 compared to 1995 and an other expense of $.1 million in 1995 relating to
a one-time charge incurred by the ILEC segment.

    FIBER.  Income before income taxes and extraordinary items from the
Company's fiber operations decreased $.1 million to a loss of $.1 million for
the year ended December 31, 1996 from 1995. The decrease in income before taxes
and extraordinary items is a result of increased interest and depreciation due
the addition of fixed assets necessary to support the growth in the fiber
operations.
 
    ICP.  Loss before income taxes and extraordinary items from the Company's
ICP operations decreased $.3 million to $.3 million for the year ended December
31, 1996 from 1995. In 1995 and 1996 the ICP operations consisted of network
management services provided to Company affiliates. The decrease in income
before income taxes and extraordinary items is a result of increased cost of
service and related SG&A.
 
IMPACT OF YEAR 2000 ISSUE
 
    In April of 1998, the Company established a multi-disciplined team to
perform a Year 2000 Impact Analysis for the corporation. 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.
 
    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, identified specific compliance requirements, and estimated costs
and completion dates for affected systems.
 
    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 acquired companies. Management has determined that American Telco's OSS is
not Year 2000 compliant; however, the Company believes its new OSS which will
replace American Telco's, will be Year 2000 compliant and will be in place by
2000. As a result, the remediation approach is not focused on a large scale
in-house effort, but on identifying those systems and services that are not
currently Year 2000 compliant and either upgrading to a compliant version or
replacing with an alternative compliant product or service. The results of the
Impact Analysis revealed that for most of the Company's information systems,
services and telecommunications infrastructure, Year 2000 compliant releases
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 by the second quarter
of 1999. The total costs identified to upgrade or replace those systems that are
not Year 2000 compliant and will not be upgraded through existing maintenance or
service agreements are approximately $.1 million. Additionally, such costs will
be expensed as incurred, which will have an adverse effect on the current
operating results.
 
    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, customers and others with which it does business to coordinate Year
2000 compliance. To further mitigate risks, the Company will conduct its own
Year 2000 tests on mission critical systems as their Year 2000 compliant
versions are released by vendors.

LIQUIDITY AND CAPITAL RESOURCES
 
   
    The Company has historically generated positive cash flow and Adjusted
EBITDA from its ILEC and fiber businesses and historically financed its ILEC
business through government loans. The Company has experienced negative cash
flow from operations and Adjusted EBITDA in 1997 and through the first six
months of 1998 in its ICP business. The magnitude of these negative cash flows
from operations and Adjusted EBITDA in the ICP business will be mitigated with
the acquisition of American Telco which has historically generated positive cash
flow from operations and Adjusted EBITDA. The Company expects negative cash flow
and Adjusted EBITDA on a consolidated basis for the remainder of 1998 and to
continue as the Company expands its ICP operations.
    
 
   
    The Company has historically generated positive cash flow from operations
and Adjusted EBITDA in its ILEC and fiber businesses. The Company's ILEC
business has also historically generated income before income taxes,
extraordinary items and cumulative effect of change in accounting principle. The
Company's ILEC business receives support revenue from federal and state agencies
that accounted for approximately 30.9%, 36.1%, 35.6%, 35.7% and 30.9% of its
revenues for the years ended December 31, 1995, 1996 and 1997 and the six months
ended June 30, 1997 and 1998. This support revenue contributes significantly to
the ILEC's positive cash flow from operations, Adjusted EBITDA and income before
income taxes, extraordinary items and cumulative effect of change in accounting
principle. See "Risk Factors--Regulation." Positive cash flow, Adjusted EBITDA
and income before income taxes, extraordinary items and cumulative effect of
change in accounting principle generated by the Company's fiber business has
grown steadily over the past several years as the Company's fiber revenues have
grown. The Company expects that its fiber revenue level will continue to grow as
more customers are added and additional capacity is sold to existing customers.
The fiber businesses' income before income taxes, extraordinary items and
cumulative effect of change in accounting principle have also been favorably
impacted by the $11.5 million capital contribution made to it by Dobson
Communications in December, 1997. This capital contribution was made in the form
of assumption of the fiber business' debt, such that the fiber business
currently does not incur any interest expense. The Company has experienced
negative cash flow from operations and Adjusted EBITDA and loss before income
taxes, extraordinary items and cumulative effect of change in accounting
principle in 1997 and the first six months of 1998 in its ICP business. These
negative cash flows from operations and Adjusted EBITDA and loss before income
taxes, extraordinary items and cumulative effect of change in accounting
principle are primarily the result of selling, general and administrative
expenses incurred as the Company works to start and expand this business. The
magnitude of these negative cash flows from operations and Adjusted EBITDA in
the ICP business will be mitigated with the acquisition of American Telco which
has historically generated positive cash flow from operations and Adjusted
EBITDA. However, the positive impact on cash flow from operations and Adjusted
EBITDA will be offset by increased interest incurred as a result of the Notes.
The Company will continue to incur losses before income taxes, extraordinary
items and cumulative effect of change in accounting principle and will continue
to generate negative cash flow from operations and Adjusted EBITDA until it
develops and expands its ICP operations and customer base. The Company expects
negative cash flow and loss before income taxes, extraordinary items and
cumulative effect of change in accounting principle on a consolidated basis for
the remainder of 1998 and to continue as the Company expands its ICP operations.
    
 
    Continued expansion of the Company's ICP business will require substantial
capital to purchase and install switches and other transmission equipment, to
replace the Company's OSS and other back office systems and to fund operating
requirements. The successful implementation of the Company's strategy, including
the expansion of its networks and customer base, and significant and sustained
growth in the Company's cash flows is necessary for the Company to meet its debt
service requirements, including its obligations on the Notes.
 
    The Company's net cash provided by operating activities was $1.9 million,
$1.4 million, $3.7 million, $6.3 million and $3.7 million for the six months
ended June 30, 1997 and 1998, and the years ended December 31, 1995, 1996 and
1997, respectively. The Company's net cash used in investing activities was
 
                                       52
<PAGE>
$1.2 million, $136.9 million, $4.2 million, $5.5 million and $3.5 million for
the six months ended June 30, 1997 and 1998, and the years ended December 31,
1995, 1996 and 1997, respectively, primarily related to capital expenditures,
and more recently, the funding of American Telco Acquisition. Net cash provided
by (used in) financing activities was $(.8) million, $217.0 million, $(.2)
million, $(.6) million and $(.6) million for the six months ended June 30, 1997
and 1998, and the years ended December 31, 1995, 1996 and 1997, respectively.
The net cash provided by financing activities during the six months ended June
30, 1998 was primarily resulted from the issuance of the Notes. The net cash
used in financing activities during the six months ended June 30, 1997 and the
years ended December 31, 1995, 1996 and 1997 primarily resulted from repayments
of long-term debt.
 
    On December 31, 1997 Dobson Communications made a capital contribution to
the Company in the form of assumption of the Company's fiber subsidiary's
obligation under a Dobson Communication's credit facility. The amount of such
capital contribution was $11.5 million.
 
    Capital expenditures for the six months ended June 30, 1997 and 1998 and the
years ended December 31, 1996 and 1997 were $1 million, $6.1 million, $3.9
million and $5.4 million, respectively. The Company expects its capital
expenditures (excluding the purchase price and related costs incurred to
consummate the acquisitions) to total approximately $58.1 million for 1998 and
approximately $23.5 million for 1999, of which $48.8 million and $15.8 million,
respectively, relate to the ICP operations. The capital expenditures will be
primarily for the purchase of switches and related equipment and infrastructure
enhancements, including the replacement of its OSS and back office systems. The
Company currently does not plan to add additional fiber optic lines to its
long-haul network, although it will seek to expand to additional cities through
interconnection agreements with other carriers. Continued significant capital
expenditures for the ICP operations are expected to be made after 1999. The
amount and timing of capital expenditures may differ materially from the
foregoing estimate depending on numerous factors, including the rate at which
the Company expands and develops its networks and customer base, the Company's
ability to negotiate favorable prices for purchases of equipment and to acquire
and integrate necessary OSS and other back office systems, whether the Company
consummates additional acquisitions and factors beyond the Company's control,
such as economic conditions, competition, market and regulatory developments and
availability of capital. In May 1998 the Company entered into a two year carrier
service agreement with Sprint for long distance capacity which provides for a
minimum commitment of $9.75 million, subject to upward adjustment depending on
actual use. In connection with the Zenex Acquisition, the Company entered into a
an agreement with WorldCom whereby the Company will lease long distance capacity
for thirty-six months with an aggregate minimum commitment during the term of
the lease of $36 million. On June 30, 1998, the Company agreed to purchase $25.2
million of switching equipment prior to June 30, 2000 for the Company's recently
launched ICP operations. Also on June 30, 1998, agreed to purchase certain
customer support services over a 60 month period ending in July 2000 for $13.7
million.
 
    Upon consummation of the American Telco Acquisition, the Company purchased
$121 million of Pledged Securities, consisting of U.S. government securities,
that will be held as security for the payment of the first six scheduled
payments of interest on the Notes. The Pledged Securities will be held by the
Trustee as security for the benefit of the holders of the Notes. Upon
consummation of the Exchange Offer, the Company will withdraw $4.3 million of
the Pledged Securities from the escrow account. See "Description of the
Notes--Security." The Trustee will hold the Pledged Securities pursuant to an
escrow and security agreement pending disbursement.
 
    As of June 30, 1998, the Company had $378.0 million of indebtedness
(including $28.0 million of secured indebtedness under the RUS/RTB Facility) and
stockholder's equity of $14.3 million. See "Description of Certain
Indebtedness." The RUS/RTB loans have scheduled maturities between 1998 and
2028. Although there can be no assurance, management believes that cash flow
from operations and borrowings under the RUS/RTB Facility will be sufficient to
fund the replacement of its OSS and the expansion of its business as currently
planned, including its negative cash flow from its ICP operations. The Company
has and will continue to incur significant increases in expenses associated with
these activities
 
                                       53
<PAGE>
   
which will significantly reduce its Adjusted EBITDA until it can develop and
expand its ICP service customer base. Thereafter, the Company expects to require
additional financing. In the event that the Company's plans or assumptions
change or prove to be inaccurate, or its cash resources prove to be insufficient
to fund the Company's growth and operations, or if the Company consummates
additional acquisitions, the Company may be required to seek additional sources
of capital (or seek additional sources of capital sooner than currently
anticipated). The Company may also seek to raise additional capital to take
advantage of favorable conditions in the capital markets. Sources of additional
capital may include public or private debt or equity financings, including
vendor financing. Because of the restrictions in the lending agreements and note
indentures of Dobson Communications, capital contributions to the Company will
be essentially prohibited. There can be no assurance that any additional
financing will be available to the Company, or if available, that it can be
obtained on terms acceptable to the Company or within the limitations contained
within the Company's financing arrangements, including the Indenture. Failure to
obtain such financing could result in the delay or abandonment of some or all of
the Company's development or expansion plans and could have a material adverse
effect on the Company's business. Such failure could also limit the ability of
the Company to make principal and interest payments on its outstanding
indebtedness, including the Notes. The Company has no credit facility under
which it may borrow for working capital and other general corporate purposes.
There can be no assurance that such a facility will be available to the Company
in the future or that if such a facility were available, that it would be
available on terms and conditions acceptable to the Company. See "Risk
Factors--Leverage; Ability to Meet Required Debt Service."
    
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    In April 1998, the Accounting Standards Executive Committee ("AcSEC") issued
Statement of Position ("SOP") 98-5, "Reporting on the Costs of Start-Up
Activities," effective for fiscal years beginning after December 15, 1998. The
Company adopted this SOP as of January 1, 1998. SOP 98-5 requires costs of
start-up activities and organization costs to be expensed as incurred. The
Company recognized a pretax loss of approximately $1.1 million in the first
quarter of 1998 as cumulative effect of accounting change as a result of
adopting this SOP.
 
    In March, 1998, the AcSEC issued SOP 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use," effective for fiscal
years beginning after December 15, 1998. The Company adopted SOP 98-1 as of
January 1, 1998. It requires capitalization of the development costs of software
to be used internally (e.g. administrative processes). The Company does not
believe that the adoption of this SOP will materially impact its net income.

                                    BUSINESS
 
OVERVIEW
 
    Logix seeks to be the leading provider of integrated local, long distance,
data and other telecommunications services to small and medium-sized business
customers throughout the Southwest United States. Since 1936, the Company has
provided ILEC services in Oklahoma. In addition, Logix operates long-haul fiber
optic facilities in Oklahoma, Texas and Colorado, providing wholesale long-haul
services. Logix recently began offering switch-based ICP services in Oklahoma
City and Tulsa under its LOGIX-TM- brand name and expects to commence offering
these services in Amarillo in late 1998. Logix's management team is led by
Everett R. Dobson, the Chairman of the Board, President and Chief Executive
Officr of Dobson Communications.
 
    In order to accelerate the expansion of its ICP business, the Company
acquired Houston-based American Telco on June 15, 1998 for $131.5 million.
American Telco provides long distance and local telecommunications services to
approximately 22,400 customers in Houston, Dallas, Fort Worth, San Antonio and
Austin, of which approximately 16,400 are business customers. Management
believes there is a significant opportunity to market the Company's integrated
LOGIX-TM- product line to the existing American Telco customers and to other
small and medium-sized business customers in Texas. With over 100 direct sales
professionals, American Telco has one of the largest direct sales forces of
alternative communications services in Texas.
 
SERVICES STRATEGY
 
    The Company's objective is to be the dominant alternative provider of
integrated local, long distance and data services packaged with wireless
offerings to small and medium-sized business customers in the Southwest. The
Company has developed customer focused strategies to build market share in
existing and new markets while utilizing innovative and efficient network
deployment techniques to maximize customer satisfaction and financial returns.
The principal elements of the Company's services strategy include:
 
    DELIVERING INNOVATIVE TELECOMMUNICATIONS SOLUTIONS FOR BUSINESS
CUSTOMERS.  The Company believes that there is substantial demand from small and
medium-sized businesses for bundled telecommunications services provided on a
single monthly bill and with a single point of contact for all sales and
service. The Company offers under its LOGIX-TM- brand name local, long distance,
enhanced data, Internet, wireless and systems integration services to customers
with convenient integrated billing through its "DIRECT T-TM-" bundled service
offering. The Company believes that its DIRECT T-TM- products allow the Company
to improve customer retention, increase sales force productivity and rapidly
increase penetration in its target markets. The Company's sales professional are
trained to provide customers with sales and customer service relating to all of
the Company's DIRECT T-TM- products. Once a customer contracts with LOGIX-TM-
for services, the Company assigns a single account relations manager who has the
responsibility of proactively contacting the customer to confirm satisfaction
with existing products and to promote new services and programs.
 
    FOCUSING ON THE SOUTHWEST.  In order to leverage its extensive
telecommunications networks and long-standing customer and business
relationships in the region, the Company intends to continue to focus on the
Southwest, initially targeting Oklahoma and Texas. The Company believes that
this regional focus will enable it to take advantage of economies of scale in
management, network operations, sales and marketing. This regional concentration
of the Company's network is also expected to result in improved profit margins
based on management's belief that a significant percentage of the Company's
customers' telecommunications traffic will originate and terminate within the
region. The Company expects to expand primarily through internal growth, though
it will consider acquisitions to extend either its product line or geographic
footprint or expand its customer base. The Company recently acquired certain
long distance customers and related assets of Zenex, an Oklahoma City based
reseller of long distance and value added
 
                                       56
<PAGE>
services, for approximately $4.7 million. In connection with the Zenex
Acquisition, the Company entered into a long term contract with WorldCom for the
resale of long distance services. This contract with WorldCom provides for a
minimum volume commitment of $18.0 million over its 36 month term.
 
    BUILDING MARKET SHARE THROUGH DIRECT SALES AND SUPERIOR CUSTOMER
SERVICE.  The Company believes that the key to revenue growth in its target
markets is to acquire customers through direct sales efforts and retain those
customers by offering a high level of customer service. The Company believes
that, in servicing the small and medium-sized business market using, a
consultative, face-to-face sales and service strategy with a single point of
contact is a highly effective method of acquiring customers and developing
long-term customer relationships. The Company's branch offices provide
comprehensive support to the Company's customers. Following the American Telco
Acquisition, the Company has 18 branch offices with approximately 190 direct
sales professionals in markets in Oklahoma City, Tulsa, Houston, Dallas, Austin,
Ft. Worth and San Antonio, which will accelerate the Company's direct sales
strategy. In the future, the Company expects to significantly expand its direct
sales force and open additional branch offices in the Southwest. The Company
also seeks to build market share by installing its own telecommunications
networks in new real estate projects so that it can become the local phone
company for the tenants of that project.
 
    INCREASING PRODUCTIVITY AND EFFICIENCY THROUGH CONTINUED ENHANCEMENT OF
OSS.  The Company believes that fully integrated and scalable OSS will increase
productivity and efficiency and provide a competitive advantage. An integrated
approach to OSS will allow the Company to synchronize multiple tasks such as
provisioning, order taking, customer service and billing and provide management
with timely operating and financial data to allow it to efficiently direct
network, sales and customer service resources. The Company currently deploys
tailored systems and procedures for its OSS and other back office systems and
customer service, and intends to replace its existing OSS with a fully
integrated, scalable system which can be expanded as the Company grows its
customer base.
 
NETWORK STRATEGY
 
    The Company will seek to efficiently expand its network infrastructure to
offer facilities-based services in attractive markets while minimizing its up
front capital expenditures. The Company believes that its facilities-based
services will enable it to achieve higher gross network margins than could be
obtained by reselling such services, accelerate provisioning and to maintain
better control over the quality of the services provided to its customers. The
principal elements of the Company's network strategy include:
 
    MAXIMIZING OPERATING MARGINS WITH A TARGETED SERVICE AREA.  The Company
targets customers within a specified geographic zone surrounding its network
infrastructure, thereby controlling the cost of services. By focusing its sales
efforts on customers within these zones and bypassing the ILEC's switch and
directly connecting these customers to a LOGIX switch using unbundled loops or
high capacity circuits, the Company believes it can generate higher gross
margins than could be obtained by reselling ILEC services.
 
    EMPLOYING ADVANCED REMOTE SWITCHING TECHNOLOGY.  In entering new markets the
Company intends to deploy an ANP unit (i.e., a smaller switch) that is linked
via leased lines to the Company's switches. The ANP unit enables the Company to
provide digital local and long distance switched services and ATM-based data
services to customers in the market area at significantly lower initial capital
costs than is required for a Class V switch. As customer telecommunications
traffic warrants, the Company will install a Class V switch and redeploy the ANP
to a new market area. By using ANP units and Class V switches, the Company
believes it will have lower operating costs than reselling. This strategy
enables the Company to optimize its capital expenditure, rapidly expand into new
markets, and generate the operating margins and quality of service provided by
dedicated facilities.
 
                                       57
<PAGE>
    CONTROLLING SERVICE QUALITY.  The Company's strategy is to have direct
control of the quality of service and responsiveness to its customers by
utilizing the Company's own switches and providing a direct connection which
eliminates the reliance on other switching providers, in contrast to reselling.
 
LEVERAGING EXISTING OPERATIONS AND PROVEN MANAGEMENT TEAM
 
    The Company believes that its ability to leverage its existing local
exchange and fiber operations and to draw upon its senior management's extensive
experience and expertise in facilities-based telecommunications services will
provide it with a competitive advantage. Everett R. Dobson, the Company's
Chairman of the Board and Chief Executive Officer, and Chairman, President and
Chief Executive Officer of Dobson Communications, the Company's parent, directed
Dobson Communications' rural cellular expansion. Stephen T. Dobson, President of
Logix, has operated Logix's ILEC business since 1990 and initiated the Company's
expansion into ICP services. William J. Hoffman, Jr., the Company's Chief
Operating Officer, joined Dobson Communications in October 1997 from Intermedia
Communications, where he was Division Vice President of its Florida markets.
Collectively, the executives of the Company have in excess of 125 years of
telecommunications experience.
 
MARKET OPPORTUNITIES
 
    The Company seeks to be the leading provider of integrated local, long
distance, data and wireless telecommunications services to small and
medium-sized businesses in the Southwest United States, initially focusing on
Texas and Oklahoma. The FCC estimates that the total United States interstate
and intrastate telephone revenues (including wireless revenues) in 1996 were
over $220 billion, of which Texas and Oklahoma accounted for $15.1 billion and
$2.3 billion, respectively. Texas was the third highest state by total revenue,
behind California and New York. Texas' revenue was split $9.5 billion intrastate
and $5.6 billion interstate, while Oklahoma's revenue was split $1.3 billion
intrastate and $1.0 billion interstate.
 
    Historically, businesses throughout the United States have purchased their
telecommunication services from different vendors: local services from RBOCs,
long distance and wide area data services from IXCs, internet services from
internet service providers, and wireless services from a wireless service
providers. The use of multiple vendors and the lack of availability of bundled
services have resulted in customers receiving multiple invoices for these
services.
 
    The Company believes that small and medium-sized businesses desire a fully
integrated package of services, with one monthly invoice and a single point of
contact for all sales and service. The Company further believes that regulatory
changes introduced by the Telecommunications Act, advances in technology, and
its experience and expertise in providing facilities-based communications
services place it in a unique position to take advantage of the large
telecommunications market in the Southwest United States.
 
THE AMERICAN TELCO ACQUISITION
 
    Dobson Wireline currently provides ICP services in Oklahoma City and Tulsa,
Oklahoma and plans to expand these operations into the major markets in Texas,
including Amarillo in late 1998. The acquisition of American Telco will
significantly accelerate Logix's expansion into the Texas market. American Telco
provides telecommunications services, primarily to business customers, in the
five largest markets in Texas: Houston, Dallas, Austin, Fort Worth and San
Antonio. It provides a unique complement to the Company's Texas expansion
strategy with 11 sales offices, approximately 100 sales representatives, and
switches in Houston and Dallas. American Telco has approximately 22,400
customers to whom it sells primarily long distance services, of which
approximately 16,400 are business customers. The Company believes there is a
significant opportunity to market its integrated LOGIX-TM- product line to the
existing American Telco business customers and to other small and medium-sized
business customers in Texas.

SERVICES
 
ILEC
 
    Since 1936, the Company has provided ILEC services and currently owns and
operates nine contiguous local exchanges in western Oklahoma and three
contiguous local exchanges adjacent to and east of the Oklahoma City
metropolitan area. At June 30, 1998 the Company's local telephone exchanges
served approximately 12,932 access lines. The Company provides local and long
distance telecommunications services with enhanced and value-added calling and
billing features.
 
    The Company's ILEC operations receive HCF from state jurisdictions and the
federal USF due to factors such as the geographic conditions and subscriber
density in the areas in which it provides service. Approximately 35.6% and 30.9%
of the Company's ILEC revenues for the year ended December 31, 1997 and the six
months ended June 30, 1998, respectively, were from these two sources. The
Company's other primary sources of ILEC revenues consisted of end user and
access revenues. End user revenues consist of charges for local service and
enhanced services such as call waiting and call forwarding. Access revenue
represents amounts charged to IXCs for providing access from the IXC's point of
presence to the end user who makes or receives a long distance call.
 
FIBER
 
    The Company provides long-haul transport services in Texas, Oklahoma and
Colorado (i) on a wholesale basis as a "carriers' carrier", (ii) to private
business and government end-users, and (iii) for Dobson Communication's other
subsidiaries. The Company has long-haul service contracts with various
long-distance carriers, including AT&T, SWBT, Sprint and NTS. NTS, which, in
turn, resells to MCI and WorldCom, is the largest customer of the Company's
fiber services, accounting for approximately 49% and 41% of its gross fiber
revenue for the years ended December 31, 1996 and 1997, respectively, and
approximately 32% for the six months ended June 30, 1998. The Company also
provides services to the State of Oklahoma and Vyvx.
 
ICP
 
    Logix's ICP services include: (i) competitive local exchange services, (ii)
enhanced data services, (iii) Internet, intranet and extranet services, (iv)
interexchange (long distance) services, (v) private line services, and (vi)
integration services.
 
    LOCAL EXCHANGE SERVICES.  These include telephone services that connect a
customer's telephone or PBX to the public network and provide the customer with
access to long distance services, operator and directory assistance services,
911 service, integrated service digital network ("ISDN") services, voice mail
and other enhanced local features.
 
    ENTERPRISE NETWORK SERVICES.  These include the switching and transport of
digitized data (and voice) over a network designed to provide highly reliable,
flexible service and support of many data transmission protocols. The Company's
enterprise network services are provided over a network of frame relay and ATM
data switches owned and leased by the Company. The Company is also able to
provide remote access to businesses providing connectivity to corporate
networks.

    INTEREXCHANGE (LONG DISTANCE) SERVICES.  These services include the
origination and termination of telephone calls between users in different cities
or exchanges. The Company provides these services on a usage basis, utilizing
its local/long distance switches, its inter-city network and services provided
by other carriers. The Company also offers inbound "800" and "888" long distance
services and nationwide calling card services.
 
    PRIVATE LINE SERVICES.  The Company provides dedicated communications
channels connecting discreet end points. These non-switched services can be
provided to two locations within the same city, or between locations in
different cities (interexchange private lines). The Company also provides
special access services connecting a customer to an IXC for the purpose of
delivering long distance calls to the IXC. The Company provides "carriers'
carrier" wholesale long-haul services to other telecommunications companies.
 
    INTEGRATION SERVICES.  These services include initial evaluation of a
customer's needs, the provision and custom configuration of network devices,
normally located at the customer's premises, which may include any special
engineering, installation, or service functions provided by the Company and
ongoing maintenance and training.
 
NETWORK INFRASTRUCTURE
 
ICP
 
    The Company installed a Nortel DMS 500 supernode switch in Oklahoma City in
1997 for its ICP services in Oklahoma City and Tulsa. American Telco has a DSC
DEX-600 long distance switch and a Siemens-Stromberg Carlson DCO local switch in
Houston, and a Siemens-Stromberg Carlson DCO local switch in Dallas. The Company
will continue to utilize American Telco's switches for an interim period after
consummation of the American Telco Acquisition, but intends to replace such
switches with more efficient ones and redeploy the old switches to areas better
suited for their specifications. Some of American Telco's customers utilize call
processors which belong to the Company but are located at the customer premises.
These call processors have enhanced routing, disaster recovery and accounting
features and can be remotely managed by American Telco.
 
    The Company's Interconnection Agreements with SBC and GTE allow it to (i)
resell SBC's and GTE's local exchange services in Oklahoma and Texas and (ii)
interconnect the Company's network with SBC's and GTE's networks for the purpose
of immediately gaining access to all of SBC's and GTE's unbundled network
elements. Based on these agreements, the Company is able to deploy its network
to enter new markets and offer local exchange services.
 
                                       60
<PAGE>
    The Company has agreements with various long-haul transport carriers to
transport the data and voice signals of its customers through its switches. The
Company also enters into agreements with various carriers to provide
transmission and termination services for its long distance traffic. Such
agreements typically provide for the resale of long distance services on a per
minute basis, with some agreements containing minimum volume commitments.
 
    In entering new markets the Company intends to deploy an ANP unit that is
linked via leased lines to the Company's switches. As customer
telecommunications traffic warrants, the Company will install a Class V switch
and redeploy the ANP to a new market area. The Company will install its ANP unit
or switch and related equipment at a central location in each market and deploy
transmission equipment in ILEC central offices. The Company will initially lease
local network trunking facilities from the ILEC and/ or one or more ICPs in
order to connect the Company's ANP unit or switch to major ILEC central offices
serving the target market area. As each customer is obtained, service will be
provisioned by leasing unbundled loops from the ILEC.
 
    In connection with the Company's enterprise network services, the Company
will expand its ATM network by installing ATM data switches and related
equipment in the Southwest. This expanded network will enable the Company to
market its enterprise network services to businesses with branch offices
throughout the Southwest. The Company will lease additional fiber capacity to
connect these ATM switches.
 
ILEC
 
    Logix serves 12,932 access lines in western Oklahoma and east of the
Oklahoma City metropolitan area with 13 switches located in Oklahoma.
 
FIBER
 
    The Company operates over 545 miles of long-haul fiber optic facilities. The
Company entered the fiber business in 1990 when it joined with AT&T to place
fiber between Oklahoma City and Amarillo, which links the Company's local
exchanges. The Company and AT&T each has its own cable, sharing in all legal
rights to the private right-of-way where the cables are located. The Company's
cable covers approximately 360 route miles and consists of 36 strands of fiber.
In 1991, the Company acquired a 20% interest in Forte of Colorado Partnership
which has 24 strands of fiber from Springfield, Colorado, to Colorado Springs,
approximately 185 miles in length. One of the Company's partners in Forte of
Colorado is NTS. To enhance the revenue potential for the above segments, the
Company, Forte of Colorado and other segment providers have interconnected their
networks and currently offer fiber-based transport services among Albuquerque,
Amarillo, Cheyenne, Colorado Springs, Dallas, Denver, Des Moines, El Paso,
Kansas City, Las Cruces, Lubbock, Oklahoma City, Omaha, Midland, Wichita and
Wichita Falls. Other segment providers have expressed interest in
interconnecting to this network and expansion may occur north to Chicago, south
to Houston and San Antonio, and east toward Atlanta. There can be no assurance
that such expansion will occur to all or any of these cities, or if such
expansion does occur, when it may occur or on what terms and conditions. While
the Company currently has no plans to add additional fiber optic lines, it will
seek to expand its network to additional cities through new interconnection
agreements.
 
SALES AND MARKETING
 
    The Company believes there is substantial demand from small and medium-sized
business for bundled telecommunications services provided with a single monthly
bill and a single point of contact. While the Company's customer focus is on
small and medium-sized businesses, it also markets to large corporations,
financial services companies, government departments and agencies, and academic,
scientific and other major institutions. The Company also seeks to build market
share by installing its own telecommunications
 
                                       61
<PAGE>
networks in new real estate projects so that it can become the local phone
company for the tenants of that project. To date the Company has installed
telecommunication networks in 13 real estate projects.
 
    The Company's ICP services, are sold through the Company's existing sales
force supported by sales engineers, and often in cooperation with agents and
value added resellers (independent providers of communications hardware to
customers) and other business associates. This approach enables the Company to
emphasize the applications solutions aspects of its services and utilize the
expertise and resources of other vendors. The Company intends to continue
expanding its sales and engineering support staff and other technical
specialists in order to meet the expected demand for ICP services.
 
    The Company's sales force includes specialized professionals who focus on
sales to commercial and carrier consumers and alternate channels (agents and
value added resellers). The Company's sales staff works to gain a better
understanding of the customer's operations in order to develop innovative,
application-specific solutions to each customer's needs. Sales personnel locate
potential business customers by several methods, including customer referral,
market research, cold calling and other networking alliances. The Company's
sales group also seeks to obtain building entry agreements with owners of
multiple office building complexes.
 
    As a result of the acquisition of American Telco, the Company has 16 branch
offices with more than 120 sales professionals located in Oklahoma City, Tulsa,
Houston, Dallas, Austin, Fort Worth and San Antonio. Each branch office will be
staffed by personnel capable of marketing all of the Company's products and
providing comprehensive support to the Company's customers. Adding this number
of sales professionals located at various branch offices in target markets will
allow the Company to accelerate its strategy of face-to-face sales and a single
point of contact for all its customers. The Company believes there is a
significant opportunity to market its integrated LOGIX-TM- product line to the
existing American Telco business customers and to other small and medium-sized
business customers in Texas.
 
    The Company markets its fiber services through its direct and indirect sales
force. The Company intends to initiate additional marketing programs to increase
its customer base and the use of its fiber network by its existing customers.
 
    The Company believes that it has a competitive advantage in the market area
that it serves because it has the only long-haul fiber network between Oklahoma
City and Amarillo, other than AT&T. AT&T's network, however, does not branch off
to small communities between Oklahoma City and Amarillo. By expanding its
network through interconnect agreements to access other major population centers
(including routes which may be attractive to major carriers) and providing
high-quality, reliable transmission services on a fixed-cost basis at
competitive rates, the Company believes it can increase its fiber revenue.
 
CUSTOMER SERVICE
 
    The Company's sales and marketing approach is to build long-term business
relationships with its customers, with the intent of becoming the single source
provider of all of their telecommunications services. To this end, the Company
assigns a dedicated account relations manager to each business account who is
responsible for proactively contacting the customer on a monthly basis. These
managers ensure that customers are satisfied with their current services and
promote new services and programs. Management believes that this activity
improves customer retention, enhances penetration within the existing customer
base and provides the Company with qualified sales leads through referrals.
 
    The Company's service delivery staff is primarily responsible for
coordinating service and installation activities. Service delivery activities
include surveying the site to assess ambient conditions and power, and space
requirements, as well as coordinating installation dates and equipment delivery
and testing. The Company's customer service and technical staff plans,
engineers, monitors and maintains the integrity, quality and availability of the
Company's networks. The Company's customer service and technical staff are
available to customers 24 hours every day.

COMPETITION
 
    GENERAL.  The telecommunications industry is highly competitive and the
Company faces intense current and potential competition with respect to its
service offerings. Many of the Company's current and potential competitors have
financial, technical, personnel and other resources, including brand name
recognition, substantially greater than those of the Company. There has also
been, and the Company believes there will continue to be, significant merger and
joint venture activity and the creation of strategic alliances within the
telecommunications industry that will result in competitors with even greater
financial resources and other competitive advantages. In addition, rapidly
evolving technology, and new applications of existing technology, may also
provide competitors in the Company's markets with significant competitive
advantages over the Company. The Company believes that various legislative
initiatives, including the Telecommunications Act and certain state initiatives,
will facilitate the ability of RBOCs, other ILECs and IXCs to offer bundled
services, allowing such entities to leverage their extensive existing networks
and provide customers with single source telecommunications services similar to
the services provided by the Company. There can be no assurance that the Company
will be able to respond to such competitive pressures or that competition will
not have a material adverse effect on the Company. See "Risk Factors--
Competition."
 
    LOCAL SERVICES.  In each of its markets where the Company operates as a ICP,
the Company faces significant competition for the local services it offers from
RBOCs and other ILECs, which currently dominate their local telecommunications
markets. In particular, SBC is the ILEC and the dominant local services provider
in most of the markets currently served by the Company. These companies all have
long-standing relationships with their customers and have financial, personnel
and technical resources substantially greater than those of the Company. As a
recent ICP market entrant, the Company has not achieved, and does not expect to
achieve a significant market share for its services.
 
    In the Texas markets, the Company also faces competition in most markets in
which it operates from one or more ICPs, including GTE, ACSI, ICG, Allegiance
Telecom and Intermedia. Other local service providers have operations or are
initiating operations within one or more of the Company's service areas. The
Company expects long distance carriers, including AT&T, Sprint and WorldCom, to
offer local services together with their long distance services in certain
markets. At least two of these competitors, AT&T and WorldCom, have entered or
announced plans to enter a number of the Company's service areas.
 
    In addition, the recent trend toward mergers and strategic alliances among
RBOCs and larger telecommunications carriers since passage of the
Telecommunications Act raises serious questions about the adverse effect of
these mergers and alliances upon the development of competition in the
telecommunications industry. On June 24, 1998, AT&T announced its proposed
acquisition of Tele-Communications, Inc. On May 11, 1998, SBC and Ameritech
announced their merger which, if approved, would reduce the seven original RBOCs
to four. If approved, this merger would leave one RBOC, SBC, with control of a
significant portion of the local exchange and business access lines in the U.S.
It also will significantly reduce competition between RBOCs, such as Ameritech's
previously announced plans to launch local service in Texas and St. Louis,
Missouri in 1998 and in other markets within SBC's region. At the same time,
SBC's competitors have won less than two percent of SBC's market share in its
local markets as a whole. SBC already has merged with Pacific Bell, and a merger
with Southern New England Telecommunications in Connecticut is pending. Two
other RBOCs, Bell Atlantic and NYNEX have merged. WorldCom has acquired MFS
Communications Co., Inc., Brooks Fiber Properties, Inc. and MCI. In January
1998, AT&T announced plans to acquire another ICP, Teleport. In June 1998 Qwest
acquired LCI.
 
    On May 6, 1998, US WEST announced that it had entered into a marketing
arrangement with Qwest whereby US WEST would market Qwest long distance services
to US WEST's in-region customers. One week later, Ameritech announced a similar
marketing arrangement with Qwest to market long distance services to Ameritech's
in-region customers. On May 14 and 15, 1998 a coalition of ICPs and
interexchange
 
                                       63
<PAGE>
carriers filed suits in federal district courts in Seattle and Chicago seeking a
declaratory ruling that US WEST and Ameritech are providing long distance
services in violation of the Telecommunications Act. The plaintiffs are seeking
a preliminary and final injunction prohibiting US WEST and Ameritech from
marketing in their regions the long distance services of Qwest or any other long
distance carrier. On June 4, 1998, the federal district court in Seattle granted
the coalition's request for a preliminary injunction preventing US WEST from
marketing to additional customer under its Qwest teaming agreement. On June 10,
1998, the federal district court in Chicago denied a preliminary injunction of
the Ameritech/Qwest joint marketing agreement; however, on June 30, 1998, the
FCC ordered Ameritech to cease marketing Qwest long distance service for 90 days
while the FCC rules on the legality of the joint marketing agreement. In March
1997 BellSouth and IBM also announced an alliance to provide Internet and
intranet services to businesses in the southern United States.
 
    The Company also expects certain cable television providers to enter its
local service markets. Other potential competitors of the Company include
utility companies and wireless telephone systems operators and private networks
built by large end-users. The Company cannot predict the number of competitors
that will emerge as a result of existing or any new federal and state regulatory
or legislative actions.
 
    In the market areas where the Company operates as an ILEC, the Company is
the sole provider of local services. The Telecommunications Act requires the
Company to interconnect its ILEC networks with the networks of other ICPs at
rates that are reasonable and non-discriminatory. As a result, other ICPs,
including SBC, could negotiate interconnection agreements with the Company and
resell the Company's local exchange services in its market areas.
 
    Competition in all of the Company's geographic market areas is based on
price, quality, reliability, customer service and responsiveness and service
features. The Company has kept its prices at levels competitive with those of
the ILECs while providing, in the opinion of the Company, a higher level of
service and responsiveness to its customers.
 
    Although the ILECs are generally subject to greater pricing and regulatory
constraints than other local network service providers, ILECs are achieving
increasing pricing flexibility for their local services as a result of recent
legislative and regulatory developments. The ILECs have continued to lower
rates, resulting in downward pressure on certain dedicated and switched access
transport rates. This price erosion has decreased operating margins for these
services. However, the Company believes this effect will be more than offset by
the increased revenues available as a result of access to customers provided
through interconnection co-carrier agreements and the opening of local exchange
service to competition. In addition, the Company believes that lower rates for
dedicated access will benefit other services offered by the Company.
 
    ENHANCED DATA SERVICES.  The Company faces competition in its enhanced data
services business from ILECs, IXCs, very small aperture terminal ("VSAT")
providers, ISPs, Internet software providers and others. Many of the Company's
existing and potential competitors have financial and other resources
significantly greater than those of the Company.
 
    The Company competes with the larger IXCs on the basis of price, service
responsiveness and a rapid response to technology and service trends. All of the
major IXCs, including AT&T, Sprint and WorldCom offer frame relay services and
several of the major IXCs have announced plans to provide Internet services. The
Company believes it competes favorably with these providers in its markets,
based on the features and functions of its services and its experience and
in-house expertise. Continued aggressive pricing is expected to support
continued rapid growth, but will place increasing pressure on operating margins.
 
                                       64
<PAGE>
    The Company also competes with VSAT services on the basis of price and data
capacity. The Company believes that the relatively low bandwidth of each VSAT
terminal and the cost of purchasing and installing VSAT equipment limits the
ability of VSAT to compete with the frame relay services provided by the
Company.
 
    Many of the ILECs now offer services similar to the Company's enhanced data
services, but offer them only on an intraLATA basis. While the ILECs generally
cannot interconnect their frame relay networks with each other, the Company has
interconnected its frame relay network with those of various ILECs. As a result,
the Company can use certain ILEC services to keep its own costs down when
distributing into areas that cannot be more economically serviced on its own
network. The Company expects the ILECs to aggressively expand their enhanced
data services as regulatory developments permit them to deploy interLATA long
distance networks. When the ILECs are permitted to provide such services, they
will be in a position to offer single source service similar to that being
offered by the Company. In February 1998, the RBOCs, US WEST, Bell Atlantic and
Ameritech, petitioned the FCC under Section 706 of the Telecommunications Act to
allow them to build and operate packet- and cell-switched data networks across
LATA boundaries, to permit them to carry interLATA data traffic incident to
their provision of digital subscriber line services, to not require them to make
those data services available on a discounted resale basis, and to not require
them to make the non-bottleneck elements of such services available on an
unbundled basis. The Company provides or may provide certain services with which
these proposed services (or similar services offered by other RBOCs) would
compete if these petitions are granted by the FCC.
 
    LONG DISTANCE.  The long distance market has relatively insignificant
barriers to entry, high average churn rate, numerous entities competing for the
same customers and prices that have declined and are expected to continue to
decline. The Company believes that it competes on the basis of price, customer
service, accurate billing, clear pricing policies and, to a lesser extent,
variety of services. The numerous current and potential competitors in the
market include AT&T, Sprint, WorldCom, Excel, Qwest, other ICPs, microwave and
satellite carriers and private networks owned by large end-users. The Company
also may increasingly face competition from firms offering long distance data
and voice services over the Internet, which firms could enjoy a significant cost
advantage because they currently do not pay carrier access charges or universal
service fees.
 
    RBOCs, such as SBC, are currently allowed to provide interLATA long distance
services outside their regions, as well as interLATA mobile services within
their regions. Under the Telecommunications Act, the RBOCs will be allowed to
provide interLATA long distance services within their regions after meeting
certain requirements intended to foster opportunities for local telephone
competition. While some RBOCs have applied for in region, interLATA approval, no
such applications have been approved to date. If the SBC Decision, however,
which ruled that the provisions of the Telecommunications Act restricting
interLATA service by the RBOCs are unconstitutional is upheld, RBOCs, including
SBC, would be allowed immediately to enter the interLATA market on a region-wide
basis irrespective of the progress towards local telephone competition. See
"--Regulation."
 
    In providing interexchange services, the Company focuses on quality service
and economy to distinguish itself in a very competitive marketplace. The Company
has built a loyal customer base by emphasizing its customer service. The
additional new services that are offered as the Company implements its local
exchange services should further support this position by allowing the Company
to market a wide array of fully integrated telecommunications services. While
these services are subject to highly competitive pricing pressures, the
Company's cost to provide these services is decreasing as it deploys more
local/long distance voice switches and interexchange network facilities.
 
                                       65
<PAGE>
FIBER
 
    In providing bulk long-haul fiber capacity the Company's primary competitors
are IXC Communications, Inc., Qwest and AT&T. AT&T is the largest supplier of
long distance voice and data transmission services in the United States and has
a transmission line adjacent to the Company's between Oklahoma City and
Amarillo. The Company also competes with other facilities-based IXCs, such as
WorldCom and Sprint, all of which have substantially greater financial resources
than the Company and a far more extensive transmission network than the
Company's network. In Oklahoma, the Company's principal competitor is a
subsidiary of SBC. The Company may also face competition from the RBOCs, GTE and
others such as electric utilities and cable television companies, including both
wireless and satalite.
 
REGULATION
 
    OVERVIEW.  The Company's services are subject to federal, state and local
regulation. The Company, through its subsidiaries, holds various federal and
state regulatory authorizations. The FCC exercises jurisdiction over
telecommunications common carriers to the extent they provide, originate or
terminate interstate or international communications. The FCC also establishes
rules and has other authority over certain issues related to local telephone
competition. State regulatory commissions retain jurisdiction over
telecommunications carriers to the extent they provide, originate or terminate
intrastate communications. Local governments may require the Company to obtain
licenses, permits or franchises in order to use the public rights of way
necessary to install and operate its networks.
 
    FEDERAL REGULATION.  The Company is categorized as a non-dominant carrier by
the FCC, and as a result is subject to relatively limited regulation of its
interstate and international services. Certain general policies and rules apply,
as well as certain reporting requirements, but the Company's rates are not
subject to prior FCC Approval. The Company has all the operating authority
required by the FCC to conduct its long distance business at present. As a
non-dominant carrier, the Company may install and operate additional facilities
for the transmission of domestic and international interstate communications
without prior FCC authorization, except to the extent that radio licenses or
international authorizations are required.
 
    The FCC also imposes prior approval requirements on transfers of control and
assignments of radio and microwave licenses and operating authorizations for the
provision of international communications services. The FCC has the authority
generally to condition, modify, cancel, terminate or revoke licenses and
operating authority for failure to comply with federal laws and/or the rules,
regulations and policies of the FCC. Fines or other penalties also may be
imposed for such violations. There can be no assurance that the FCC or third
parties will not raise issues with regard to the Company's compliance with
applicable laws and regulations.
 
    The FCC also regulates the interstate access rates charged by ILECs for the
origination and termination of interstate long distance traffic. Those access
rates make up a significant portion of the cost of providing long distance
service. The FCC has recently implemented changes to its interstate access rules
that result in restructuring of the access charge system and changes in access
charge rate levels. These changes reduce per-minute access charges and
substitute new per-line flat-rate monthly charges. These actions, and additional
anticipated access charge reductions ordered by regulatory commissions in the
future, are expected to reduce access rates, and hence the cost of providing
long distance service, especially to business customers. However, the full
impact of the FCC's new decisions will not be known until those decisions are
implemented over the next several years, during which time those decisions may
be revised or subject to judicial review. In a related proceeding, the FCC has
adopted changes to the methodology by which access has been used in part to
subsidize universal telephone service and other public policy goals.
Telecommunications providers like the Company must pay a fee calculated as a
percentage of their end user gross revenues derived from telecommunication
services to support these goals. The full implications of this decision also
remain uncertain and subject to change. In addition, the FCC and the courts are
 
                                       66
<PAGE>
considering related questions regarding the applicability of access charge, and
universal service fees to Internet service providers. Currently such providers
are not subject to these expenses. ILECs and other parties argue that this
exemption unfairly advantages Internet service providers, particularly when they
provide data, voice or other services in direct competition with conventional
telecommunications. The Company is not in a position to determine how these
access and universal service matters will be resolved, and whether or not such
resolution will be harmful to its competitive position.
 
    In October 1996, the FCC adopted an order in which it eliminated the
requirement that non-dominant interstate carriers such as the Company maintain
tariffs on file with the FCC for domestic interstate services. This order
applies to all non-dominant interstate carriers, including AT&T. The order does
not apply to the switched and special access services of the RBOCs or other
local exchange providers. The FCC order was issued pursuant to authority granted
to the FCC in the Telecommunications Act to "forbear" from regulating any
telecommunications services provider if the FCC determines that the public
interest will be served. Several parties have filed notices for reconsideration
of the FCC order and other parties appealed the decision. On February 13, 1997,
the United States Court of Appeals for the District of Columbia Circuit stayed
the implementation of the FCC order pending its review of the order on the
merits. Currently, that temporary stay remains in effect.
 
    If the stay is lifted and the FCC order becomes effective,
telecommunications carriers such as the Company will no longer be able to rely
on the filing of tariffs with the FCC as a means of providing notice to
customers of prices, terms and conditions on which they offer their interstate
services. The obligation to provide non-discriminatory, just and reasonable
prices remains unchanged under the Communications Act of 1934, as amended by the
Telecommunications Act. While tariffs provided a means of providing notice of
prices, terms and conditions, the Company intends to rely primarily on its sales
force and direct marketing to provide such information to its customers.
 
    The Telecommunications Act also gives the FCC and state PUCs roles in
establishing rules for the implementation of local telephone competition. The
Telecommunications Act imposes a variety of new duties on ILECs in order to
promote competition in local exchange and access services, and the FCC has
authority to develop rules to implement these duties. Some smaller independent
ILECs may seek suspension or modification of these obligations, and some
companies serving rural areas are exempt from them.
 
    In that regard, on August 8, 1996, the FCC released the Local Competition
Order to implement the interconnection, network unbundling and resale provisions
of the Telecommunications Act. The Local Competition Order established rules
pursuant to which ILECs interconnect their networks with the networks of
competitive local exchange carriers at rates that are reasonable and
non-discriminatory. The Local Competition Order also established rules governing
the rights of ICPs to obtain and use elements of the ILECs' networks at
cost-based rates either to supplement or substitute for alternative local
network facilities that the ICP would otherwise be required to install. The
Local Competition Order set rules governing competitive local exchange carrier
access to wholesale versions of the ILECs' retail local services for resale. The
ILECs are required to establish administrative support systems so that these
services and functionalities can be made available to other carriers on a
nondiscriminatory basis. The Local Competition Order also created rules to deal
with reciprocal compensation for the transport and termination of local
telecommunications, non-discriminatory access to rights of way, and related
matters. A related FCC order adopted the same day established rules implementing
the Telecommunications Act with respect to local and toll dialing parity among
competitors; nondiscriminatory access to telephone numbers, operator services,
directory assistance and listings, and network information; and reform of
numbering administration.
 
    The Local Competition Order was challenged in the federal courts by GTE, the
RBOCs, large independent ILECs and state regulatory commissions. On October 15,
1996, the U.S. Court of Appeals for the Eighth Circuit issued a stay of the
implementation of certain of the FCC's rules and on July 18 and
 
                                       67
<PAGE>
October 14, 1997, the Eighth Circuit issued decisions finding that the FCC
lacked statutory authority under the Telecommunications Act for a major portion
of its rules. In particular, the Eighth Circuit found that the FCC was not
empowered to establish national pricing standards governing unbundled local
network elements or wholesale local services of the ILECs, or to require such
carriers to provide network elements in a combined form. The Eighth Circuit also
struck down other FCC rules, including one that would have enabled new entrants
to "pick and choose" from provisions of approved interconnection agreements
between the ILECs and other carriers. The Eighth Circuit, however, rejected
certain other objections to the FCC rules brought by the ILECs or the states,
including challenges to the FCC's definition of unbundled elements, and to the
FCC's rules allowing new competitors to create their own networks by combining
incumbent local exchange carrier network elements together without adding
additional facilities of their own. The overall impact of the Eighth Circuit's
decisions are to limit the obligations of ILECs as originally interpreted by the
FCC, materially reduce the role of the FCC in fostering local competition,
including its ability to take enforcement action if the Telecommunications Act
is violated, and increase the role of state utility commissions. On January 26,
1998, the Supreme Court granted a request by the FCC and other parties to review
the Eighth Circuit decisions. A decision from the Supreme Court is not expected
until early 1999. Meanwhile, certain state commissions have asserted that they
will be active in promoting local telephone competition under the authority of
the Eighth Circuit decisions, which have not been stayed, and this may minimize
some of the significance of the reduced FCC role. However, at this time, it is
premature to assess the impact of the Eighth Circuit's decisions and there can
be no assurance that these decisions and related developments will not have a
material adverse effect on the Company. Indeed, a number of state commissions
have set prices for unbundled network elements that are substantially higher and
wholesale discount rates lower for resold services than the Local Competition
Order provided on an interim basis. Furthermore, other FCC rules related to
local telephone competition remain the subject of legal challenges, and there
can be no assurance that decisions affecting those rules will not be adverse to
companies seeking to enter the local telephone market.
 
    There can be no assurance that the FCC's remaining rules (including such
rules that may be reinstated by the Supreme Court, if any), together with rules
adopted by state public utility commissions, will be implemented in a manner
that will permit local telephone competition to develop to a substantial extent
and without significant delays. For example, many new carriers, including the
Company, have experienced problems with respect to the operational support
systems used by new carriers to order and receive network elements and wholesale
services from the ILECs. These systems are necessary for new carriers like the
Company to provide local service to customers on a timely and competitive basis.
The FCC created a task force to examine problems that have slowed the
development of local telephone competition.
 
    In connection with offering local exchange services, the Company has entered
into approved interconnection agreements with SBC and GTE in Texas and Oklahoma
permitting the Company to (i) resell SBC's and GTE's local exchange services in
Oklahoma and Texas, (ii) interconnect the Company's network with SBC's and GTE's
networks for the purpose of exchanging local traffic with ILEC customers, and
(iii) immediately gain access to all of SBC's and GTE's unbundled network
elements. The Company is also negotiating interconnection agreements with SBC in
Arkansas, Kansas and Missouri, and with BellSouth in Louisiana and Tennessee.
 
    As a general matter, no assurance is possible regarding how quickly or how
adequately the Company will be able to take advantage of the opportunities
created by the Telecommunications Act. The Company could be adversely affected
if the Eighth Circuit's decisions reversing some of the FCC's local competition
rules, or problems in the related arbitration and negotiation process, result in
increasing the cost of using incumbent local exchange carrier network elements
or services, or if such actions otherwise result in delays in the implementation
of the Telecommunications Act or impediments to the development of local
telephone competition.

    The Telecommunications Act also imposes certain duties on non-ILECs, such as
the Company. These duties include the obligation to complete calls originated by
competing carriers under reciprocal arrangements or through mutual exchange of
traffic without explicit payment; the obligation to permit resale of their
telecommunications services without unreasonable restrictions or conditions; and
the duty to provide dialing parity, number portability, and access to rights of
way. The Company does not anticipate that these obligations will impose a
material burden on its operations. However, in view of the fact that local
telephone competition is still in its infancy and implementation of the
Telecommunications Act has just begun, there can be no assurance in this regard.
 
    The Telecommunications Act also establishes the foundation for substantial
new future competition for the Company's long distance operations through
elimination or modification of previous prohibitions on the provision of
interLATA long distance services by the RBOCs. The RBOCs are now permitted to
provide interLATA long distance service outside those states in which they offer
local exchange service ("out-of-region long distance service") upon receipt of
any necessary state and/or federal regulatory approvals. They also are allowed
to provide long distance services for their cellular and other mobile services
within the regions in which they also provide local exchange service ("in-region
service"). Under the Telecommunications Act, the RBOCs will be allowed to
provide wireline in-region services upon specific approval of the FCC and
satisfaction of other conditions, including a checklist intended to facilitate
competitive entry into local exchange markets. GTE is permitted to enter the
long distance market without regard to limitations by region. GTE is also
subject to the provisions of the Telecommunications Act that impose
interconnection and other requirements on local exchange carriers. SBC and other
RBOCs have begun to take actions directed towards obtaining authority from the
FCC to offer in-region long distance services in certain of the states in their
respective regions. The FCC forced the withdrawal of the first RBOC request for
in-region long distance authority, and rejected the next four applications.
However, there can be no assurance that the RBOC's will be prevented from
offering in-region long distance service until local competition is established.
The Eighth Circuit recently rejected the FCC's attempt to condition interLATA
entry on compliance with certain pricing principles that the Court had
previously found were outside the jurisdiction of the FCC to mandate as a
general matter. Other court actions are now pending challenging the terms under
which the FCC has denied an in-region application. Furthermore, on December 31,
1997, the U.S. District Court for the Northern District of Texas in the SBC
Decision ruled in favor of SBC that the Telecommunications Act provisions
restricting interLATA services by the RBOCs were unconstitutional. Although that
decision has been stayed pending appeal, it may, if sustained on appeal, allow
SBC to enter the interLATA market on a region-wide basis irrespective of the
state of local competition.
 
    If the RBOCs are allowed to enter the long distance market prior to
establishing local competition, absent additional safeguards it would remove the
incentive RBOCs have to cooperate with the Company's efforts to offer local
exchange services.
 
    The ability of the RBOCs to provide interLATA services will enable them to
provide customers with a full range of local and long distance
telecommunications services. The provision of interLATA services by RBOCs is
expected to reduce the market share of the major long distance carriers, which
are the Company's networks' primary customers. Consequently, the entry of the
RBOCs into the long distance market may have adverse consequences on the ability
of ICPs both to generate access revenues from the IXCs and to compete in
offering a package of local and long distance services. To date FCC authority to
provide in-region interLATA service has been sought by Ameritech in Michigan,
SBC in Oklahoma and BellSouth in South Carolina and Louisiana. In March 1998,
the U.S. Court of Appeals for the District of Columbia Circuit affirmed the
FCC's denial of SBC's application for long distance authority in Oklahoma. The
Department of Justice opposed each of these requests, and the FCC denied them.
More RBOC requests to provide in-region interLATA service are expected to be
filed with state commissions and the FCC in the near future. SBC has
applications pending with state commissions through its in-region states,
including Oklahoma. On June 3, 1998, the Texas PUC rejected SBC's application to
provide in-region
 
                                       69
<PAGE>
interLATA service. Although SBC can be expected to refile its application with
the Texas PUC, this is a significant short-term development for IXCs and ICPs
operating in Texas and in neighboring states in SBC's region.
 
    The FCC has granted ILECs certain flexibility in pricing their interstate
special and switched access services. Under this pricing scheme, local exchange
carriers may establish pricing zones based on access traffic density and charge
different prices for access provided in each zone. The Company anticipates that
the FCC will grant ILECs increasing pricing flexibility as the number of
interconnection agreements and competitors increases. In a pending rulemaking
proceeding scheduled for completion soon, the FCC is expected to announce new
and more specific policies regarding the conditions and timing under which ILECs
will be eligible for such increased pricing flexibility. There can be no
assurance that such pricing flexibility will not place the Company at a
competitive disadvantage, either as a purchaser of access for its long distance
operations, or as a vendor of access to other carriers or end user customers.
 
    The Telecommunications Act repeals the telco/cable cross-ownership
prohibition and permits ILECs to provide cable television service. Prior to the
Telecommunications Act repeal, some ILECs were investing in fiber optic networks
on a limited basis through the FCC's "video dialtone" regulatory regime. With
the telco/cable cross ownership prohibition removed, ILECs are more likely to
invest in fiber optic networks because those facilities will be able to generate
a revenue stream previously unavailable on a widespread basis to the ILECs.
While ILEC entry into the video market may be a motivating factor for
construction of new facilities, these facilities also can be used by an ILEC to
provide services that compete with the Company's networks.
 
    On May 8, 1997, the FCC released the Universal Service Order establishing a
significantly expanded federal telecommunications subsidy regime. For example,
the FCC established new subsidies for telecommunications and information
services provided to qualifying schools and libraries with an annual cap of $2.3
billion and for services provided to rural health care providers with an annual
cap of $400.0 million. The FCC also expanded the federal subsidies to low-income
consumers. Providers of interstate telecommunications service, such as the
Company, as well as certain other entities, must pay for these programs. The
Company's share of these federal subsidy funds will be based on intrastate,
interstate and international "end user" gross telecommunications revenues
effective January 1, 1998. For the first two quarters of 1998, the assessment
for the rural, high cost and low income fund has been 3.19% and 3.14% of
interstate and international end user telecommunications revenues. For the same
period, the assessment for schools and libraries and rural health care funds
("S/L") was 0.76% of intrastate, interstate, and international end user
telecommunications services. However, while the FCC has proposed a slightly
lower assessment for the rural, high cost and low income fund for the third
quarter of 1998 (3.08%), the proposed S/L factor of 1.54% is more than double
the comparable rate for the second quarter. In the May 8th order, the FCC also
announced that it will soon revise its rules for subsidizing service provided to
consumers in high cost areas, which may result in further substantial increases
in the overall cost of the subsidy program. Several parties have appealed the
May 8th order. Such appeals have been consolidated and transferred to the United
States Court of Appeals for the Fifth Circuit where they are currently pending.
In addition, on July 3, 1997, several ILECs filed a petition for stay of the May
8th order with the FCC. That petition is pending as well as several other
petitions for reconsideration.
 
    In addition, on May 16, 1997, the FCC released the Access Charge Reform
Order revising its access charge rate structure. The new rules substantially
increase the costs that local exchange carriers which are subject to the FCC's
price cap rules, recover through monthly, non-traffic sensitive access charges
and substantially decrease the costs that price cap LECs recover through traffic
sensitive access charges. In the order, the FCC also announced its plan to bring
interstate access rate levels more in line with cost. The FCC has stated that
this plan will grant price cap LECs increased pricing flexibility upon
demonstrations of increased competition (or potential competition) in relevant
markets. The manner in which the FCC further implements this approach to
lowering access charge levels could have a material effect on the Company's
ability to compete in providing interstate access services and on the Company's
ILEC
 
                                       70
<PAGE>
operations. An October 1997 FCC access charge decision, for example, requires
local exchange carriers to provide interexchange carriers with certain
information about the number and types of charges they impose on interexchange
carriers' presubscribed customers. Several parties have appealed the Access
Charge Reform Order. Those appeals have been consolidated and transferred to the
United States Court of Appeals for the Eighth Circuit where they are currently
pending.
 
    The Telecommunications Act potentially impacts the Company's ILEC
operations. Under previous regulations access charges contained implicit support
for high-cost areas. The FCC has initiated proceedings to overhaul the
contribution mechanism for federal support revenue. On May 16, 1997, the FCC
issued the Access Charge Reform Order that would remove implicit universal
service support from access revenues and place more emphasis for such support on
HCF/USF. To the extent reductions in access charges are not offset by explicit
universal service subsidies, this could have a materially adverse effect upon
the Company's operations. Until such time as the appeals of the Universal
Service Order and/or Access Charge Reform Order are decided, there can be no
assurance of how either of these Orders will be implemented or enforced or what
effect the Orders will have on competition within the telecommunications
industry generally, or on the competitive position of the Company, in
particular.
 
    A number of ILECs, including SBC and BellSouth, have been contesting whether
the obligation to pay reciprocal compensation to ICP's should apply to local
telephone calls terminating to Internet service providers ("ISPs"). The ILECs
claim that this traffic is interstate in nature and therefore should be exempt
from compensation arrangements applicable to local, intrastate calls. The FCC,
however, has determined on a number of occasions, most recently in its May 16,
1997, access charge reform order, that calls to ISPs should be exempt from
interstate access charges and should be governed by local exchange tariffs.
Currently, the commissions of nineteen states, including Maryland, Michigan, New
York, Oklahoma, Tennessee, Texas and Virginia, have ruled that reciprocal
compensation arrangements do apply to ISP traffic. On June 16, 1998, a federal
district court in Texas denied SBC's appeal of the Texas PUC's decision that
local calls to ISPs are entitled to payment of reciprocal compensation. Disputes
over the appropriate treatment of ISP traffic are pending in other states.
 
    STATE REGULATION.  The Company is also subject to various state laws and
regulations. Most public utility commissions require providers such as the
Company to obtain authority from the commission prior to the initiation of
intrastate service. The Company has been certified to provide intrastate
telecommunications services in Oklahoma and Texas. The certification permits the
Company to provide a range of local communications services, including basic
local exchange service, resold inter-exchange service, and competitive access
service. In most states, including Texas and Oklahoma, the Company also is
required to file tariffs setting forth the terms, conditions and prices for
services that are classified as intrastate. The Company also is required to
update or amend its tariffs when it adjusts its rates or adds new products, and
is subject to various reporting and record-keeping requirements.
 
    Dobson Telephone is subject to the regulatory authority of the OCC, which
sets rates, terms and conditions of service, and mandates minimum service and
quality of service requirements for telephone companies in Oklahoma. Telephone
companies in Oklahoma have elected to be access providers, providing long
distance service only between their own exchanges. Interexchange carriers,
including SBC, provide all other long distance services for other customers.
Logix has received authority to provide competitive local exchange
telecommunications services and to resell intrastate long distance services
within Oklahoma and has received authority to resell intrastate long distance
services within Texas. American Telco has received authority to provide
competitive local exchange telecommunication services and to resell intrastate
long distance services within Texas.
 
    Many states also require prior approval for transfers of control of
certified carriers, corporate reorganizations, acquisitions of
telecommunications operations, assignment of carrier assets, carrier stock
offerings and incurrence by carriers of significant debt obligations.
Certificates of authority can generally be conditioned, modified, canceled,
terminated or revoked by state regulatory authorities for failure to comply with
state law and/or the rules, regulations and policies of state regulatory
authorities. Fines or
 
                                       71
<PAGE>
other penalties also may be imposed for such violations. There can be no
assurance that state utilities commissions or third parties will not raise
issues with regard to the Company's compliance with applicable laws or
regulations.
 
    Many issues remain open regarding how new local telephone carriers will be
regulated at the state level. For example, although the Telecommunications Act
preempts the ability of states to forbid local service competition, the
Telecommunications Act preserves the ability of states to impose reasonable
terms and conditions of service and other regulatory requirements. However,
these statutes and related questions arising from the Telecommunications Act
will be elaborated further through rules and policy decisions made by the FCC,
courts and PUCs in the process of addressing local service competition issues.
 
    The Company also will be heavily affected by state commission decisions
related to the ILECs, particularly in view of the decisions of the Eighth
Circuit noted above which resulted in a larger role for state commissions and a
reduced role for the FCC. For example, state commissions have significant
responsibility under the Telecommunications Act to oversee relationships between
ILECs and ICPs with respect to use of the ILECs' network elements and wholesale
local services. State commissions arbitrate interconnection agreements between
the incumbent local exchange carrier pricing issues in major proceedings now
underway. They will also determine how competitors can take advantage of the
terms and conditions of interconnection agreements that ILECs reach with other
carriers. It is too early to evaluate how these matters will be resolved, or
their impact on the ability of the Company to pursue its business plan.
 
    States also regulate the intrastate carrier access services of the ILECs.
The Company is required to pay such access charges to originate and terminate
its intrastate long distance traffic. The Company could be adversely affected by
high access charges, particularly to the extent that the ILECs do not incur the
same level of costs with respect to their own intrastate long distance services.
In a related development, states also will be developing intrastate universal
service charges parallel to the interstate charges created by the FCC. For
example, ILECs such as SBC are proposing that states create funds that would be
supported by potentially large payments by firms such as the Company based on
their total intrastate revenues. Another issue is use by certain ILECs, with the
approval of PUCs, of extended local area calling that converts otherwise
competitive intrastate toll service to flat rate local service. States also are
or will be addressing various intraLATA dialing parity issues that may affect
competition. The Company's business could be adversely affected by these or
other developments.
 
    The Company's ILEC operations have been determined by the OCC to be eligible
to receive both federal universal funds and OUSF and HCF funds. The Oklahoma
Telecom Act specifically provides that eligible local exchange
telecommunications service providers are to receive OUSF funding to reimburse
them for their reasonable investment and expenses incurred in providing
universal services which are not recovered from the federal universal service
fund or any other state or federal fund, for infrastructure expenditures or
costs incurred in response to facility or service requirements established by
governmental mandate and for other purposes deemed necessary by the OCC to
preserve and advance universal service. The OCC is promulgating rules to
implement the Oklahoma Telecom Act. The interpretation of the Oklahoma Telecom
Act and application of the OCC rules implementing the OUSF could have a material
effect on Company's operations.
 
    The Company also will be affected by how states regulate the retail prices
of the ILECs with which it competes. The Company believes that, as the degree of
intrastate competition increases, the states will offer the ILECs increasing
pricing flexibility. This flexibility may present the ILECs with an opportunity
to subsidize services that compete with the Company's services with revenues
generated from non-competitive services, thereby allowing ILECs to offer
competitive services at lower prices than they otherwise could. In a related
development, certain RBOCs are seeking authority to create "ICP" affiliates that
would operate on a much less regulated basis and therefore could provide
significant competition in the business market whether or not the traditional
ILEC local business receives more pricing flexibility. The Company
 
                                       72
<PAGE>
cannot predict the extent to which these developments may occur or their impact
on the Company's business.
 
    LOCAL GOVERNMENT AUTHORIZATIONS AND RELATED RIGHTS OF WAY.  The Company is
required to obtain street use and construction permits and licenses and/or
franchises to install and expand its fiber optic networks using municipal rights
of way. In some municipalities where the Company has installed or anticipates
constructing networks, it will be required to pay license or franchise fees
based on a percentage of gross revenues or on a per linear foot basis. There can
be no assurance that, following the expiration of existing franchises, fees will
remain at their current levels. In many markets, the ILECs do not pay such
franchise fees or pay fees that are substantially less than those required to be
paid by the Company, although the Telecommunications Act requires that in the
future such fees be applied in a competitively neutral manner. To the extent
that, notwithstanding the Telecommunications Act, competitors do not pay the
same level of fees as the Company, the Company could be at a competitive
disadvantage. Termination of the existing franchise or license agreements prior
to their expiration dates or a failure to renew the franchise or license
agreements and a requirement that the Company remove its facilities or abandon
its network in place could have a material adverse effect on the Company. In
addition, the Company would be adversely affected if it is unable to obtain
additional authorization for new construction on reasonable terms. Furthermore,
open issues exist regarding the ability of new local service providers to gain
access to commercial office buildings to serve tenants. Two favorable federal
district court decisions interpreting the Telecommunications Act limit the
extent to which Texas localities may impose right-of-way regulations and fees on
the Company where the Company resells the services of ILECs and other
facilities-based carriers. However, no assurance can be given that these
decisions will not be subject to appeal or that future court decisions, either
in Texas or other states, will prove favorable to the Company.
 
    GENERAL.  The telecommunications market is in a period of substantial change
and uncertainty. As the Telecommunications Act and related FCC and state actions
are implemented, new issues are likely to arise that can affect the Company and
its business plan. No assurance can be given that future regulatory developments
will not have a materially adverse impact on the Company.
 
EMPLOYEES AND AGENTS
 
    As of June 30, 1998, the Company had approximately 490 employees. In
addition, the Company also enters into agreements with independent sales agents
to market its products. None of the Company's employees are represented by a
labor organization, and the Company considers its employee relations to be good.
 
PROPERTIES
 
    Dobson Communications maintains its corporate headquarters in Oklahoma City,
Oklahoma. The Company leases a portion of this space, which is approximately
6,025 square feet, from an affiliate of the Company at a monthly rental of
approximately $9,750. See "Management--Certain Transactions." The Company also
owns 12 switch sites and leases 19 sales and administrative offices and four
switch sites at aggregate annual rentals of approximately $1.5 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 and switch
sites in connection with the expansion of its business. The Company does not
anticipate that it will encounter any material difficulties in meeting its
future needs for any leased space.
 
LEGAL PROCEEDINGS
 
    The Company is not currently involved in any pending legal proceedings that
individually or in the aggregate are material to the Company. The Company is a
party to routine filings and customary regulatory proceedings with the FCC, OCC
and state PUCs relating to its operations.

(1) Everett R. Dobson and Stephen T. Dobson are sons of Russell L. Dobson.
 
    Logix was incorporated under the name "Dobson Wireline Company" in December
1997 in connection with a corporate reorganization (the "Reorganization")
pursuant to which Dobson Communications segregated its wireline and wireless
activities and became the holding company parent of Dobson Operating Company
("DOC"). In October 1998, the Company changed its name to "Logix Communications
Enterprises, Inc."
 
    EVERETT R. DOBSON has served as a Chairman and Chief Executive Officer of
the Company since its formation in December 1997 and as a director and officer
of Dobson Communications since 1982. From 1990 to 1996, he served as a director,
President and Chief Operating Officer of Dobson Communications and President of
Dobson Communications' cellular subsidiaries. He was elected Chairman of the
Board and Chief Executive Officer of Dobson Communications in April 1996. Mr.
Dobson devotes approximately 40% of his time to the Company. Mr. Dobson served
on the board of the Cellular Telecommunications Industry Association ("CTIA") in
1993 and 1994. He holds a B.A. in Economics from Southwestern Oklahoma State
University ("SWOSU") where he currently sits on the SWOSU Foundation Board and
chairs the investment committee.
 
    STEPHEN T. DOBSON has been President and a director of the Company since
March 1998, and has served as an officer of the Company since its incorporation
in 1997. He has been a director of Dobson
 
                                       74
<PAGE>
Communications since 1990. He has served as Treasurer and Secretary of Dobson
Communications since 1990 and General Manager and Secretary of Dobson Telephone
since 1994 and 1990, respectively. However, Mr. Dobson devotes substantially all
of his time to the Company. He became President of Logix Communications
Corporation ("LOGIX") in January 1997. Mr. Dobson is a member of the Western
Rural Telephone Association ("WRTA"), National Telephone Cooperative Association
and Telecommunications Resellers Association. He holds a B.S. in business
administration from the University of Central Oklahoma.
 
    WILLIAM J. HOFFMAN, JR. joined Dobson Communications as Vice President and
Chief Operating Officer and Vice President and Chief Operating Officer of the
Company in October 1997. Mr. Hoffman devotes substantially all of his time to
the Company. Prior to joining Dobson Communications, Mr. Hoffman was employed by
Intermedia Communications, Inc. as Division Vice President--Florida Division
from 1995 to 1997 and from 1987 to 1995 by Sprint Communications, serving as
Branch Manager, Senior National Account Manager, Product Marketing Manager and
National Account Consultant. He was a Captain in the U.S. Army in Europe working
in military intelligence from 1983 to 1987. Mr. Hoffman holds a B.S. in
electrical engineering from Auburn University.
 
    JAMES R. RUTHERFORD became President of Dobson Telephone Company in March
1998. Mr. Rutherford has been employed by Dobson Communications and its
subsidiaries since 1988 and has worked in various capacities, including manager
and coordinator of contract engineering and construction, outside plant manager,
general manager, and assisted in the start-up and development of the Logix's ICP
operations. Prior to joining Dobson Telephone, Mr. Rutherford was employed by
C.H. Guernsey & Co., a telecommunications engineering firm, for ten years
working in outside plant engineering and design, and project coordination. He
serves as a director of the Oklahoma High Cost Fund Board and is actively
involved in the Oklahoma Telephone Association ("OTA") and the WRTA industry
organizations. In addition, Mr. Rutherford serves on the Oklahoma Rural
Telephone Companies technical and regulatory committees.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    Logix does not have a separate compensation committee of its board of
directors. The board of directors sets the compensation for its executive
officers and Everett R. Dobson, Chairman of the Board, and Stephen T. Dobson,
President, are directors and participate in these deliberations concerning
executive officer compensation. Each of the directors of Logix also serve on the
board of directors of Dobson Communications and on the boards of directors of
various subsidiaries of Dobson Communications. As such, each of the directors
participates in the deliberations concerning executive officers' compensation
for Dobson Communications and its subsidiaries.
 
EMPLOYMENT AGREEMENTS
 
    In connection with the employment of William J. Hoffman, Jr. in 1997, Dobson
Communications agreed to provide compensation in the form of a combination of
some or all of the following: salary, bonus, stock options and/or other
benefits. The terms of Mr. Hoffman's employment are a $10,000 payment upon
 
                                       78
<PAGE>
acceptance of employment, an initial annual salary of $110,000, an annual bonus
ranging from 30% to 50% of his annual salary, country club initiation fees and
dues, a five-year option to purchase 664 shares of Dobson Communications' Class
B Common Stock at an exercise price equal to its fair market value at date of
grant, with 60% of the options vesting ratably over five years and 40% vesting
over five years based on the achievement of annual performance objectives. Mr.
Hoffman is also entitled to a severance payment equal to one year's salary in
the event of termination of employment of Mr. Hoffman without cause. The options
to purchase shares of Class B Common Stock held by Mr. Hoffman become fully
vested upon a change of control of Dobson Communications. Effective August 1,
1998, and pursuant to the Logix Stock Option Plan, the Company granted to Mr.
Hoffman options to purchase an aggregate of 1,042,500 shares of Common Stock
over a ten year term at an exercise price of $2.00 per share, which options vest
at the rate of 20% on each anniversary date of the grant. See "--Stock Option
Plan."
 
    Effective September 1, 1998, Dobson Communications entered into a consulting
agreement with Russell L. Dobson. Under the terms of the agreement, Mr. Dobson
will be 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 duties
consistent with the responsibilities of a former Chief Executive Officer of
Dobson Communication, including the development of goodwill for Dobson
Communications and the Company. During 1997, Mr. Dobson was paid $197,946 by
Dobson Communications.
 
STOCK OPTION PLANS
 
    Logix adopted a Stock Option Plan (the "Logix Plan") effective August 1,
1998. The purpose of the Logix Plan is be to encourage key employees of the
Company by providing opportunities to participate in the ownership of Logix and
its future growth through the grant of incentive stock options and nonqualified
stock options. The Logix Plan permits the grant of options to directors. The
Logix Plan is intended to be administered by the Board of Directors, but may be
administered by a committee of the Board (whether the Board or a committee, the
"Committee")
 
    The maximum number of shares of Logix Common Stock for which options may be
granted under the Plan is 3,750,000, 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 shares to be issued under the
Logix 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 Logix Common Stock at the
time of the 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
 
                                       79
<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 August 1, 2008.
 
    Effective August 1, 1998, the Company granted options to purchase an
aggregate of 1,417,500 shares at an exercise price of $2.00 share. Each option
agreement provides that the right to exercise becomes vested at the rate of 20%
on each anniversary date of the grant.
 
    Key employees of the Company may also participate in the Dobson
Communications 1996 Stock Option Plan (the "Dobson Communications Plan"). The
Dobson Communications Plan permits the grant of stock options to purchase Class
B Common Stock of Dobson Communications.
 
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 Dobson Communications be on terms no less favorable
to the Company than reasonably could have been obtained in an arm's length
transaction with independent third parties. Any other matters involving
potential conflicts of interests are to be resolved on a case-by-case basis.
 
    Dobson Communications leases its headquarters from WillRuss Limited
Liability Company ("WillRuss") pursuant to a 10-year lease expiring in 2005.
WillRuss is owned by Russell L. Dobson, a director of the Company, and his wife.
Monthly rent under the lease is approximately $23,000, or $.93 per square foot.
The Company utilizes a portion of the space leased by Dobson Communications, and
is allocated a portion of the rent. The amount allocated to the Company in 1997
was $194,000. The Company believes that the terms of this lease are no less
favorable to the Company than could be obtained in a lease from an unrelated
party.
 
    Dobson Communications owns approximately 15% of the outstanding common stock
of Zenex. Everett R. Dobson was a director of Zenex from August 1995 to
September 1997. On January 6, 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 Dobson Telephone for
$105,000. In addition, the Company recently purchased certain long distance
customers and related assets for approximately $4.5 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.
 
    Beginning in 1997 Dobson Communications began to provide certain
administrative services, including accounting, information systems management,
human resources management and marketing. Additionally, officers of Logix are
also officers of Dobson Communications and various of its other subsidiaries.
These officers perform functions for all of the Dobson Communications
subsidiaries, including Logix. Logix reimburses Dobson Communications based on
Dobson Communications' cost of providing the services. In 1997, the total amount
charged to Logix for these administrative services and officer compensation was
$1,448,000.
 
                                       80
<PAGE>
    Logix provides telephone services to Dobson Communications and its
subsidiaries. These services amounted to $338,000, $421,000 and $480,000 in
1995, 1996 and 1997, respectively.
 
    Logix, through its fiber optic network, provides long-haul transport
services to Dobson Communications' cellular subsidiaries. These services are
provided on a market rate basis. For each of 1995, 1996 and 1997, these services
amounted to $1.1 million.
 
    Logix is a party to a tax sharing agreement with Dobson Communications and
its other subsidiaries. Logix, as a member of the affiliated group with Dobson
Communications joins with Dobson Communications and its other subsidiaries in
filing a consolidated federal income tax return. Under the tax sharing
agreement, each subsidiary's contribution toward the group's consolidated
federal income tax liability is determined as if such party were at all times a
separate taxpayer not included in the group. Based on this determination of
separate tax liability, each subsidiary pays to Dobson Communications an amount
in lieu of taxes equal to the amount the subsidiary would be obligated to pay if
it filed returns as a separate taxpayer. If, but only to the extent that, the
group realizes a tax benefit for any taxable year as a result of the inclusion
of a subsidiary's tax items in the determination of tax liability of the group,
Dobson Communications will pay to the subsidiary an amount equal to such tax
benefits realized. As a result of the tax sharing agreement, Logix's liability
to Dobson Communications for income taxes $.4 million, $.4 million and $1.1
million in 1995, 1996 and 1997, respectively.
 
    As a result of various intercompany activities, Logix had receivables from
Dobson Communications and its subsidiaries totaling $11.5 million, $8.2 million
and $2.1 million at December 31, 1996, 1997 and June 30, 1998, respectively.
 
    On December 31, 1997 Dobson Communications made a capital contribution to
Logix in the form of assumption of Logix's fiber subsidiary's obligation under a
Dobson Communication's credit facility. The amount of such capital contribution
was $11.5 million.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
RUS/RTB FACILITY
 
    Dobson Telephone is a party to loan agreements with the United States of
America, Rural Utilities Services ("RUS") and the Rural Telephone Bank ("RTB")
pursuant to which the RUS and RTB have agreed to loan the Company an aggregate
maximum of $75 million at any time outstanding (the "RUS/ RTB Facility"). At
June 30, 1998, the aggregate outstanding principal balance of these loans was
$28.0 million. The loans bear interest at annual rates varying from 2% to
10 3/4% and with scheduled maturities until 2028.
 
    No loans under the RUS/RTB Facility may mature after May 2043. All advances
under the RUS/RTB Facility are secured by substantially all of Dobson
Telephone's assets, including its licenses and other intangible assets.
 
    The RUS/RTB Facility contains covenants which, among other things, require
prior approval of the applicable lending agencies before Dobson Telephone can
declare or pay dividends, make distributions to or investments in affiliates or
stockholders or redeem its capital stock, unless after such payments, Dobson
Telephone's current assets equal or exceed current liabilities and its adjusted
net worth meets specified requirements. In addition, the RUS/RTB Facility limits
Dobson Telephone's ability to merge or consolidate or sell its assets or enter
into any contracts for the operation or maintenance of its property for use by
others or for toll traffic, operator assistance, extended scope or switching
services to be furnished by or for connecting or other companies other than
contracts generally used in the telephone industry. Dobson Telephone is
restricted from advancing payments or loans to any stockholders or affiliates,
other than for certain wireline related investments unless if after such
investment, the aggregate of investments does not exceed one-third of Dobson
Telephone's net worth and its net worth is at least 20% of its total assets.
 
    The RUS/RTB Facility also provides that while Dobson Telephone's adjusted
net worth is less than 10% of its total assets, Dobson Telephone is restricted
from increasing salaries of officers or directors without the prior consent of
the majority of the noteholders. In addition, if retained earnings decrease as a
result of operations, Dobson Telephone must increase its charges for telephone
service or execute a plan for reducing expenses, each with the approval of the
noteholders. Dobson Telephone is also required to maintain a ratio of net income
or net margins plus interest expense of 1.50 to 1.
 
    Failure to satisfy any of the covenants constitutes an event of default
under the RUS/RTB Facility permitting the applicable lending agencies to
accelerate payment of the outstanding indebtedness or sell or take possession of
the mortgaged property notwithstanding Dobson Telephone's ability to meet its
debt obligations. In the event of a default in the payment of principal or
interest on the outstanding indebtedness, if in the opinion of the holders of a
majority of outstanding indebtedness, Dobson Telephone's operations are not
being efficiently operated, the Company may be required to terminate operating
contracts or the employment of certain managers. The RUS/RTB Facility also
contains certain other events of default, including forfeiture of permits or
licenses required to carry on a material portion of its business, and customary
events of default, including, without limitation, material undischarged
judgments and bankruptcy.

<PAGE>
                            DESCRIPTION OF THE NOTES
 
    The Old Notes were issued under an Indenture dated as of June 12, 1998
between the Company, as issuer, and United States Trust Company of New York (the
"Trustee"). A copy of the Indenture is available upon request from the Company.
The New Notes will be issued under the Indenture, which will be qualified under
the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), upon
effectiveness of the Registration Statement of which this Prospectus is a part.
The form and terms of the New Notes are identical in all material respects to
the form and terms of the Old Notes except that the New Notes will be registered
under the Securities Act and, therefore, will not bear legends restricting a
transfer thereof. Upon consummation of the Exchange Offer, holders of the Notes
will not be entitled to registration rights under, or the contingent increase in
interest rate provided pursuant to, the Old Notes. The New Notes will evidence
the same debt as the Old Notes and will be treated as a single class under the
Indenture with any Old Notes that remain outstanding.
 
    The terms of the Notes include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act as in effect on
the date of the Indenture. The Notes are subject to all such terms and
references made to the Indenture and the Trust Indenture Act for a statement
thereof. A copy of the Indenture has been filed with the Commission as an
exhibit to the Registration Statement of which this Prospectus is a part. The
following summary of the material provisions of the Indenture does not purport
to be complete and is subject to, and is qualified in its entirety by reference
to, all the provisions of the Indenture, including the definitions of certain
terms therein and those terms made a part thereof by reference to the Trust
Indenture Act. Whenever particular defined terms of the Indenture not otherwise
defined herein are referred to, such defined terms are incorporated herein by
reference. For definitions of certain capitalized terms used in the following
summary, see "--Certain Definitions."
 
GENERAL
 
    The Notes will be unsecured (except to the extent described under
"--Security") unsubordinated obligations of the Company, initially limited to
$350 million aggregate principal amount, and will mature on June 15, 2008. Each
Note will bear interest at the rate shown on the front cover of this Prospectus
from the Closing Date or from the most recent Interest Payment Date to which
interest has been paid or provided for, payable semiannually (to holders of
record at the close of business on the June 1 or December 1 immediately
preceding the Interest Payment Date) on June 15 and December 15 of each year,
commencing December 15, 1998. Interest will be computed on the basis of a
360-day year of twelve 30-day months.
 
    If by the date that is six months after the Closing Date, the Company has
not consummated a registered exchange offer for the Notes or caused a shelf
registration statement with respect to resales of the Notes to be declared
effective, the interest rate on the Notes shall be increased by .5% per annum
until the consummation of a registered exchange offer or the effectiveness of a
shelf registration statement. See "--Registration Rights."
 
    Principal of, premium, if any, and interest on the Notes will be payable,
and the Notes may be exchanged or transferred, at the office or agency of the
Company in the Borough of Manhattan, the City of New York (which initially will
be the corporate trust office of the Trustee at 114 W. 47th Street, New York,
New York 10036); provided that, at the option of the Company, payment of
interest may be made by check mailed to the holders at their addresses as they
appear in the Security Register.
 
    The Notes will be issued only in fully registered form, without coupons, in
denominations of $1,000 of principal amount and any integral multiple thereof.
See "--Book-Entry; Delivery and Form." No service charge will be made for any
registration of transfer or exchange of Notes, but the Company may require
payment of a sum sufficient to cover any transfer tax or other similar
governmental charge payable in connection therewith.
 
                                       84
<PAGE>
    Subject to the covenants described below under "Covenants" and applicable
law, the Company may issue additional Notes under the Indenture. The Notes
offered hereby and any additional Notes subsequently issued would be treated as
a single class for all purposes of the Indenture.
 
OPTIONAL REDEMPTION
 
    The Notes will be redeemable, at the Company's option, in whole or in part,
at any time or from time to time, on or after June 15, 2003 and prior to
maturity, upon not less than 30 nor more than 60 days' prior notice mailed by
first class mail to each holder's last address as it appears in the Security
Register, at the Redemption Prices (expressed in percentages of principal
amount) set forth below, plus accrued and unpaid interest to the Redemption Date
(subject to the right of holders of record on the relevant Regular Record Date
that is prior to the Redemption Date to receive interest due on an Interest
Payment Date), if redeemed during the 12-month period commencing June 15 of the
years set forth below:

2006 and thereafter.........................................................        100.000
</TABLE>
 
    In addition, at any time prior to June 15, 2001, the Company may redeem up
to 35% of the aggregate principal amount of the Notes with the Net Cash Proceeds
of one or more sales of Capital Stock of the Company (other than Disqualified
Stock), at any time as a whole or from time to time in part, at a Redemption
Price (expressed as a percentage of principal amount) of 112.250%, plus accrued
and unpaid interest; PROVIDED that at least 65% of the aggregate principal
amount of the Notes originally issued on the Closing Date remains outstanding
after each such redemption and notice of any such redemption is mailed within 60
days after the related sale of Capital Stock.
 
    In the case of any partial redemption, selection of the Notes for redemption
will be made by the Trustee in compliance with the requirements of the principal
national securities exchange, if any, on which the Notes are listed or, if the
Notes are not listed on a national securities exchange, by lot or by such other
method as the Trustee in its sole discretion shall deem to be fair and
appropriate; PROVIDED that no Note of $1,000 in principal amount or less shall
be redeemed in part. If any Note is to be redeemed in part only, the notice of
redemption relating to such Note shall state the portion of the principal amount
thereof to be redeemed. A new Note in principal amount equal to the unredeemed
portion thereof will be issued in the name of the holder thereof upon
cancellation of the original Note.
 
SECURITY
 
    Immediately prior to the closing of the Offering, the Company entered into
an escrow and security agreement (the "Escrow and Security Agreement") with the
Placement Agents and The United States Trust Company of New York, escrow agent
(in such capacity, the "Escrow Agent").
 
    Of the net proceeds from the Offering of the Old Notes, $121 million have
been invested in Pledged Securities held in a Pledge Account (excluding
approximately $.8 million paid as premiums). The Pledged Securities consist of
U.S. Government obligations having scheduled interest and principal payments
which exceed the amount sufficient, as estimated by Arthur Andersen LLP, to
provide for payment in full of the first six scheduled interest payments due on
all Notes then outstanding.
 
    Pursuant to the Escrow and Security Agreement, immediately prior to an
Interest Payment Date, the Company may either deposit with the Trustee from
funds otherwise available to the Company cash sufficient to pay the interest
scheduled to be paid on such date or the Company may direct the Trustee to
release from the Pledge Account proceeds sufficient to pay interest then due on
the Notes. In the event the
 
                                       85
<PAGE>
Company exercises the former option, the Company may direct the Trustee to
release a like amount of proceeds from the Pledge Account. A failure to pay
interest on the Notes in a timely manner through the first six scheduled
interest payment dates will constitute an immediate Event of Default under the
Indenture, with no grace or cure period. The Pledged Securities and Pledge
Account will also secure the repayments of the principal amount and premium on
the Notes.
 
    Under the Escrow and Security Agreement, once the Company makes the first
six scheduled interest payments on the Notes, all of the remaining Pledged
Securities, if any, will be released from the Pledge Account and thereafter the
Notes will be unsecured.
 
SINKING FUND
 
    There are no sinking fund payments for the Notes.
 
RANKING
 
    The Notes are unsubordinated indebtedness of Logix, and will rank PARI PASSU
in right of payment with all existing and future unsubordinated indebtedness of
Logix and senior in right of payment to all subordinated indebtedness of Logix.
As of June 30, 1998, the Company had (on an unconsolidated basis) no
indebtedness outstanding other than the Notes. In addition, Logix is a holding
company and the Notes will be effectively subordinated to all existing and
future liabilities (including trade payables) of the Company's subsidiaries. As
of June 30, 1998, the subsidiaries of the Company had approximately $43.4
million of liabilities (excluding intercompany payables), including
approximately $28.0 million of indebtedness, all of which indebtedness was
secured. See "Risk Factors--Leverage; Ability to Meet Required Debt Service."

is expressly made PARI PASSU with, or subordinate in right of payment to, the
remaining Notes, (B) in case the Indebtedness to be refinanced is subordinated
in right of payment to the Notes, such new Indebtedness, by its terms or by the

                                       98
<PAGE>
"Limitation on Indebtedness" covenant shall not be deemed to be exceeded, with

and delivers a supplemental indenture to the Indenture providing for a Guarantee
(a "Subsidiary Guarantee") of payment of the Notes 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
 
                                      102
<PAGE>
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
Notes, then the Guarantee of such Guaranteed Indebtedness shall be PARI PASSU
with, or subordinated to, the Subsidiary Guarantee or (B) subordinated to the
Notes, 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 Notes.
 
    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 Indenture) or (ii) the release or discharge of the Guarantee
which resulted in the creation of such Subsidiary Guarantee, except a discharge
or release by or as a result of payment under such Guarantee.
 
LIMITATION ON TRANSACTIONS WITH STOCKHOLDERS AND AFFILIATES
 
    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 or series of related transactions 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 $1 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 LIENS
 
    The Company will not, and will not permit any Restricted Subsidiary to,
create, incur, assume or suffer to exist any Lien on any of its assets or
properties of any character (including, without limitation, licenses), or any
shares of Capital Stock or Indebtedness of any Restricted Subsidiary, without
making effective provision for all of the Notes and all other amounts due under
the Indenture to be directly secured equally and ratably with (or, if the
obligation or liability to be secured by such Lien is subordinated in right of
payment to the Notes, prior to) the obligation or liability secured by such
Lien.
 
                                      103
<PAGE>
    The foregoing limitation does not apply to (i) Liens existing on the Closing
Date; (ii) Liens granted after the Closing Date on any assets or Capital Stock
of the Company or its Restricted Subsidiaries created in favor of the holders;
(iii) Liens with respect to the assets of a Restricted Subsidiary granted by
such Restricted Subsidiary to the Company or a Wholly Owned Restricted
Subsidiary to secure Indebtedness owing to the Company or such other Restricted
Subsidiary; (iv) Liens securing Indebtedness which is Incurred to refinance
secured Indebtedness which is permitted to be Incurred under clause (iii) of the
second paragraph of the "Limitation on Indebtedness" covenant; PROVIDED that
such Liens do not extend to or cover any property or assets of the Company or
any Restricted Subsidiary other than the property or assets securing the
Indebtedness being refinanced; (v) Liens on the Capital Stock of, or any
property or assets of, a Restricted Subsidiary securing Indebtedness of such
Restricted Subsidiary permitted under the "Limitation on Indebtedness" covenant;
(vi) Liens securing Indebtedness Incurred under clause (i) of the second
paragraph of the "Limitation on Indebtedness" covenant; or (vii) Permitted
Liens.
 
LIMITATION ON SALE-LEASEBACK TRANSACTIONS
 
    The Company will not, and will not permit any Restricted Subsidiary to,
enter into any sale-leaseback transaction involving any of its assets or
properties whether now owned or hereafter acquired, whereby the Company or a
Restricted Subsidiary sells or transfers such assets or properties and then or
thereafter leases such assets or properties or any part thereof or any other
assets or properties which the Company or such Restricted Subsidiary, as the
case may be, intends to use for substantially the same purpose or purposes as
the assets or properties sold or transferred.
 
    The foregoing restriction does not apply to any sale-leaseback transaction
if (i) the lease is for a period, including renewal rights, of not in excess of
three years; (ii) the lease secures or relates to industrial revenue or
pollution control bonds; (iii) the transaction is solely between the Company and
any Wholly Owned Restricted Subsidiary or solely between Wholly Owned Restricted
Subsidiaries; or (iv) the Company or such Restricted Subsidiary, within 12
months after the sale or transfer of any assets or properties is completed,
applies an amount not less than the net proceeds received from such sale in
accordance with clause (A) or (B) of the first paragraph of the "Limitation on
Asset Sales" covenant described below.
 
LIMITATION ON 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; PROVIDED, HOWEVER, that this
clause (ii) shall not apply to long-term assignments in capacity in a
telecommunications network. In the event and to the extent that the Net Cash
Proceeds received by the Company or any of its Restricted Subsidiaries from one
or more Asset Sales occurring on or after the Closing Date in any period of 12
consecutive months exceed 10% of Adjusted Consolidated Net Tangible Assets
(determined as of the date closest to the commencement of such 12-month period
for which a consolidated balance sheet of the Company and its Subsidiaries has
been filed with the Commission), then the Company shall or shall cause the
relevant Restricted Subsidiary to (i) within 12 months after the date Net Cash
Proceeds so received exceed 10% of Adjusted Consolidated Net Tangible Assets (A)
apply an amount equal to such excess Net Cash Proceeds to permanently repay
unsubordinated 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
 
                                      104
<PAGE>
engaged in a business) similar or related to the nature or type of the property
and assets of, or the business of, the Company and its Restricted Subsidiaries
existing on the date of such investment (as determined in good faith by the
Board of Directors, whose determination shall be conclusive and evidenced by a
Board Resolution) 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
12-month period as set forth in clause (i) of the preceding sentence and not
applied as so required by the end of such period shall constitute "Excess
Proceeds."
 
    If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
"Limitation on Asset Sales" covenant totals at least $5 million, the Company
must commence, not later than the fifteenth Business Day of such month, and
consummate an Offer to Purchase from the holders on a PRO RATA basis an
aggregate principal amount of Notes equal to the Excess Proceeds on such date,
at a purchase price equal to 100% of the principal amount of the Notes, plus, in
each case, accrued interest to the Payment Date.
 
REPURCHASE OF NOTES UPON A CHANGE OF CONTROL
 
    The Company must commence, within 30 days of the occurrence of a Change of
Control, and consummate an Offer to Purchase for all Notes then outstanding, at
a purchase price equal to 101% of the principal amount thereof, PLUS accrued
interest to the Payment Date.
 
    There can be no assurance that the Company will have sufficient funds
available at the time of any Change of Control to make any debt payment
(including repurchases of Notes) required by the foregoing covenant (as well as
may be contained in other securities of the Company which might be outstanding
at the time). The above covenant requiring the Company to repurchase the Notes
will, unless consents are obtained, require the Company to repay all
indebtedness then outstanding which by its terms would prohibit such Note
repurchase, either prior to or concurrently with such Note repurchase.
 
COMMISSION REPORTS AND REPORTS TO HOLDERS
 
    At all times from and after the earlier of (i) the date of the commencement
of an Exchange Offer or the effectiveness of a Shelf Registration Statement (the
"Registration") and (ii) the date that is six months after the Closing Date, in
either case, whether or not the Company is then required to file reports with
the Commission, the Company shall file with the Commission all such reports and
other information as it would be required to file with the Commission by
Sections 13(a) or 15(d) under the Exchange Act if it were subject thereto. The
Company shall supply the Trustee and each holder or shall supply to the Trustee
for forwarding to each such holder, without cost to such holder, copies of such
reports and other information. In addition, at all times prior to the earlier of
the date of the Registration and the date that is six months after the Closing
Date, the Company shall, at its cost, deliver to each holder of the Notes
quarterly and annual reports substantially equivalent to those which would be
required by the Exchange Act. In addition, at all times prior to the
Registration, upon the request of any holder or any prospective purchaser of the
Notes designated by a holder, the Company shall supply to such holder or such
prospective purchaser the information required under Rule 144A under the
Securities Act.
 
EVENTS OF DEFAULT
 
    The following events are defined as "Events of Default" in the Indenture:
(a) default in the payment of principal of (or premium, if any, on) any Note
when the same becomes due and payable, upon acceleration, redemption or
otherwise; (b) default in the payment of interest on any Note when the same
becomes due and payable, and such default continues for a period of 30 days;
provided that a failure to make any of the first six scheduled interest payments
on the Notes on the applicable Interest Payment Date
 
                                      105
<PAGE>
will constitute an Event of Default with no grace or cure period; (c) default in
the performance or breach of the provisions of the Indenture applicable to
mergers, consolidations and transfers of all or substantially all of the assets
of the Company or the failure to make or consummate an Offer to Purchase in
accordance with the "Limitation on Asset Sales" or "Repurchase of Notes upon a
Change of Control" covenant; (d) the Company defaults in the performance of or
breaches any other covenant or agreement of the Company in the Indenture or
under the Notes (other than a default specified in clause (a), (b) or (c) above)
and such default or breach continues for a period of 30 consecutive days after
written notice by the Trustee or the holders of 25% or more in aggregate
principal amount of the Notes; (e) there occurs with respect to any issue or
issues of Indebtedness of the Company or any Significant Subsidiary having an
outstanding principal amount of $5 million or more in the aggregate for all such
issues of all such Persons, whether such Indebtedness now exists or shall
hereafter be created, (I) an event of default that has caused the holder thereof
to declare such Indebtedness to be due and payable prior to its Stated Maturity
and such Indebtedness has not been discharged in full or such acceleration has
not been rescinded or annulled within 30 days of such acceleration and/or (II)
the failure to make a principal payment at the final (but not any interim) fixed
maturity and such defaulted payment shall not have been made, waived or extended
within 30 days of such payment default; (f) any final judgment or order (not
covered by insurance) for the payment of money in excess of $5 million in the
aggregate for all such final judgments or orders against all such Persons
(treating any deductibles, self-insurance or retention as not so covered) shall
be rendered against the Company or any Significant Subsidiary and shall not be
paid or discharged, and there shall be any period of 30 consecutive days
following entry of the final judgment or order that causes the aggregate amount
for all such final judgments or orders outstanding and not paid or discharged
against all such Persons to exceed $5 million during which a stay of enforcement
of such final judgment or order, by reason of a pending appeal or otherwise,
shall not be in effect; (g) a court having jurisdiction in the premises enters a
decree or order for (A) relief in respect of the Company or any Significant
Subsidiary in an involuntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect, (B) appointment of a receiver,
liquidator, assignee, custodian, trustee, sequestrator or similar official of
the Company or any Significant Subsidiary or for all or substantially all of the
property and assets of the Company or any Significant Subsidiary or (C) the
winding up or liquidation of the affairs of the Company or any Significant
Subsidiary and, in each case, such decree or order shall remain unstayed and in
effect for a period of 30 consecutive days; (h) the Company or any Significant
Subsidiary (A) commences a voluntary case under any applicable bankruptcy,
insolvency or other similar law now or hereafter in effect, or consents to the
entry of an order for relief in an involuntary case under any such law, (B)
consents to the appointment of or taking possession by a receiver, liquidator,
assignee, custodian, trustee, sequestrator or similar official of the Company or
any Significant Subsidiary or for all or substantially all of the property and
assets of the Company or any Significant Subsidiary or (C) effects any general
assignment for the benefit of creditors; or (i) the Escrow and Security
Agreement shall cease to be in full force and effect or enforceable in
accordance with its terms, other than in accordance with its terms.
 
    If an Event of Default (other than an Event of Default specified in clause
(g) or (h) above that occurs with respect to the Company) occurs and is
continuing under the Indenture, the Trustee or the holders of at least 25% in
aggregate principal amount of the Notes, then outstanding, by written notice to
the Company (and to the Trustee if such notice is given by the holders), may,
and the Trustee at the request of such holders shall, declare the principal of,
premium, if any, and accrued interest on the Notes to be immediately due and
payable. Upon a declaration of acceleration, such principal, premium, if any,
and accrued interest shall be immediately due and payable. In the event of a
declaration of acceleration because an Event of Default set forth in clause (e)
above has occurred and is continuing, such declaration of acceleration shall be
automatically rescinded and annulled if the event of default triggering such
Event of Default pursuant to clause (e) shall be remedied or cured by the
Company or the relevant Significant Subsidiary or waived by the holders of the
relevant Indebtedness within 60 days after the declaration of acceleration with
respect thereto. If an Event of Default specified in clause (g) or (h) above
occurs with respect to the Company, the principal of, premium, if any, and
accrued interest on the Notes then
 
                                      106
<PAGE>
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. The
holders of at least a majority in principal amount of the outstanding Notes 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 Notes that have become due solely by such
declaration of acceleration, have been cured or waived and (ii) the rescission
would not conflict with any judgment or decree of a court of competent
jurisdiction. For information as to the waiver of defaults, see "--Modification
and Waiver."
 
    The holders of at least a majority in aggregate principal amount of the
outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the Trustee
in personal liability, or that the Trustee determines in good faith may be
unduly prejudicial to the rights of holders of Notes not joining in the giving
of such direction and may take any other action it deems proper that is not
inconsistent with any such direction received from holders of Notes. A holder
may not pursue any remedy with respect to the Indenture or the Notes unless: (i)
the holder gives the Trustee written notice of a continuing Event of Default;
(ii) the holders of at least 25% in aggregate principal amount of outstanding
Notes make a written request to the Trustee to pursue the remedy; (iii) such
holder or holders offer the Trustee indemnity satisfactory to the Trustee
against any costs, liability or expense; (iv) the Trustee does not comply with
the request within 60 days after receipt of the request and the offer of
indemnity; and (v) during such 60-day period, the holders of a majority in
aggregate principal amount of the outstanding Notes do not give the Trustee a
direction that is inconsistent with the request. However, such limitations do
not apply to the right of any holder of a Note to receive payment of the
principal of, premium, if any, or interest on, such Note or to bring suit for
the enforcement of any such payment, on or after the due date expressed in the
Notes, which right shall not be impaired or affected without the consent of the
holder.
 
    The Indenture will require certain officers of the Company to certify, on or
before a date not more than 90 days after the end of each fiscal year, that a
review has been conducted of the activities of the Company and its Restricted
Subsidiaries and the Company's and its Restricted Subsidiaries' performance
under the Indenture and that the Company has fulfilled all obligations
thereunder, or, if there has been a default in the fulfillment of any such
obligation, specifying each such default and the nature and status thereof. The
Company will also be obligated to notify the Trustee of any default or defaults
in the performance of any covenants or agreements under the Indenture.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
    The Company will not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its property
and assets (as an entirety or substantially an entirety in one transaction or a
series of related transactions) to, any Person or permit any Person to merge
with or into the Company unless: (i) the Company shall be the continuing Person,
or the Person (if other than the Company) formed by such consolidation or into
which the Company is merged or that acquired or leased such property and assets
of the Company shall be a corporation organized and validly existing under the
laws of the United States of America or any jurisdiction thereof and shall
expressly assume, by a supplemental indenture, executed and delivered to the
Trustee, all of the obligations of the Company on all of the Notes and under the
Indenture; (ii) immediately after giving effect to such transaction, no Default
or Event of Default shall have occurred and be continuing; (iii) immediately
after giving effect to such transaction on a pro forma basis, the Company or any
Person becoming the successor obligor of the Notes shall have a Consolidated Net
Worth equal to or greater than the Consolidated Net Worth of the Company
immediately prior to such transaction; (iv) immediately after giving effect to
such transaction on a pro forma basis the Company, or any Person becoming the
successor obligor of the Notes, as the case may be, could Incur at least $1.00
of Indebtedness under the first paragraph of the "Limitation on Indebtedness"
 
                                      107
<PAGE>
covenant; PROVIDED that this clause (iv) shall not apply to a consolidation,
merger or sale of all (but not less than all) of the assets of the Company if
all Liens and Indebtedness of the Company or any Person becoming the successor
obligor on the Notes, as the case may be, and its Restricted Subsidiaries
outstanding immediately after such transaction would, if Incurred at such time,
have been permitted to be Incurred (and all such Liens and Indebtedness, other
than Liens and Indebtedness of the Company and its Restricted Subsidiaries
outstanding immediately prior to the transaction, shall be deemed to have been
Incurred) for all purposes of the Indenture; and (v) the Company delivers to the
Trustee an Officers' Certificate (attaching the arithmetic computations to
demonstrate compliance with clauses (iii) and (iv) above) and Opinion of
Counsel, in each case stating that such consolidation, merger or transfer and
such supplemental indenture complies with this provision and that all conditions
precedent provided for herein relating to such transaction have been complied
with; 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
PROVIDED FURTHER that any such transaction shall not have as one of its purposes
the evasion of the foregoing limitations.
 
DEFEASANCE
 
    DEFEASANCE AND DISCHARGE.  The Indenture provides that the Company will be
deemed to have paid and will be discharged from any and all obligations in
respect of the Notes on the 123rd day after the deposit referred to below, and
the provisions of the Indenture will no longer be in effect with respect to the
Notes (except for, among other matters, certain obligations to register the
transfer or exchange of the Notes, to replace stolen, lost or mutilated Notes,
to maintain paying agencies and to hold monies for payment in trust) if, among
other things, (A) the Company has deposited with the Trustee, in trust, money
and/or U.S. Government Obligations that through the payment of interest and
principal in respect thereof in accordance with their terms will provide money
in an amount sufficient to pay the principal of, premium, if any, and accrued
interest on the Notes on the Stated Maturity of such payments in accordance with
the terms of the Indenture and the Notes, (B) the Company has delivered to the
Trustee (i) either (x) an Opinion of Counsel to the effect that holders will not
recognize income, gain or loss for federal income tax purposes as a result of
the Company's exercise of its option under this "Defeasance" provision and will
be subject to federal income tax on the same amount and in the same manner and
at the same times as would have been the case if such deposit, defeasance and
discharge had not occurred, which Opinion of Counsel must be based upon (and
accompanied by a copy of) a ruling of the Internal Revenue Service to the same
effect unless there has been a change in applicable federal income tax law after
the Closing Date such that a ruling is no longer required or (y) a ruling
directed to the Trustee received from the Internal Revenue Service to the same
effect as the aforementioned Opinion of Counsel and (ii) an Opinion of Counsel
to the effect that the creation of the defeasance trust does not violate the
Investment Company Act of 1940 and after the passage of 123 days following the
deposit, the trust fund 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 Event of Default, or event that after the giving of notice or lapse of time
or both would become an Event of Default, shall have occurred and be continuing
on the date of such deposit or during the period ending on the 123rd day after
the date of such deposit, and such deposit shall not result in a breach or
violation of, or constitute a default under, any other agreement or instrument
to which the Company or any of its Subsidiaries is a party or by which the
Company or any of its Subsidiaries is bound and (D) if at such time the Notes
are listed on a national securities exchange, the Company has delivered to the
Trustee an Opinion of Counsel to the effect that the Notes will not be delisted
as a result of such deposit, defeasance and discharge.
 
    DEFEASANCE OF CERTAIN COVENANTS AND CERTAIN EVENTS OF DEFAULT.  The
Indenture further provides that the provisions of the Indenture will no longer
be in effect with respect to clauses (iii) and (iv) under "Consolidation, Merger
and Sale of Assets" and all the covenants described herein under "Covenants,"
clause (c) under "Events of Default" with respect to such clauses (iii) and (iv)
under "Consolidation,
 
                                      108
<PAGE>
Merger and Sale of Assets," clause (d) under "Events of Default" with respect to
such other covenants and clauses (e) and (f) under "Events of Default" shall be
deemed not to be Events of Default, upon, among other things, the deposit with
the Trustee, in trust, of money and/or U.S. Government Obligations that through
the payment of interest and principal in respect thereof in accordance with
their terms will provide money in an amount sufficient to pay the principal of,
premium, if any, and accrued interest on the Notes on the Stated Maturity of
such payments in accordance with the terms of the Indenture and the Notes, the
satisfaction of the provisions described in clauses (B)(ii), (C) and (D) of the
preceding paragraph and the delivery by the Company to the Trustee of an Opinion
of Counsel to the effect that, among other things, the holders will not
recognize income, gain or loss for federal income tax purposes as a result of
such deposit and defeasance of certain covenants and Events of Default and will
be subject to federal income tax on the same amount and in the same manner and
at the same times as would have been the case if such deposit and defeasance had
not occurred.
 
    DEFEASANCE AND CERTAIN OTHER EVENTS OF DEFAULT.  In the event the Company
exercises its option to omit compliance with certain covenants and provisions of
the Indenture with respect to the Notes as described in the immediately
preceding paragraph and the Notes are declared due and payable because of the
occurrence of an Event of Default that remains applicable, the amount of money
and/or U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on the Notes at the time of their Stated Maturity
but may not be sufficient to pay amounts due on the Notes at the time of the
acceleration resulting from such Event of Default. However, the Company will
remain liable for such payments.
 
MODIFICATION AND WAIVER
 
    Modifications and amendments of the Indenture may be made by the Company and
the Trustee with the consent of the holders of not less than a majority in
aggregate principal amount of the outstanding Notes; PROVIDED, HOWEVER, that no
such modification or amendment may, without the consent of each holder affected
thereby, (i) change the Stated Maturity of the principal of, or any installment
of interest on, any Note, (ii) reduce the principal of, or premium, if any, or
interest on, any Note, (iii) change the place or currency of payment of
principal of, or premium, if any, or interest on, any Note, (iv) impair the
right to institute suit for the enforcement of any payment on or after the
Stated Maturity (or, in the case of a redemption, on or after the Redemption
Date) of any Note, (v) reduce the above-stated percentage of outstanding Notes
the consent of whose holders is necessary to modify or amend the Indenture, (vi)
waive a default in the payment of principal of, premium, if any, or interest on
the Notes or (vii) reduce the percentage or aggregate principal amount of
outstanding Notes the consent of whose holders is necessary for waiver of
compliance with certain provisions of the Indenture or for waiver of certain
defaults.
 
NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS, OR
  EMPLOYEES
 
    The Indenture provides that no recourse for the payment of the principal of,
premium, if any, or interest on any of the Notes or for any claim based thereon
or otherwise in respect thereof, and no recourse under or upon any obligation,
covenant or agreement of the Company in the Escrow and Security Agreement, the
Indenture, or in any of the Notes or because of the creation of any Indebtedness
represented thereby, shall be had against any incorporator, stockholder,
officer, director, employee or controlling person of the Company or of any
successor Person thereof. Each holder, by accepting the Notes, waives and
releases all such liability.
 
CONCERNING THE TRUSTEE
 
    The Indenture provides that, except during the continuance of a Default, the
Trustee will not be liable, except for the performance of such duties as are
specifically set forth in such Indenture. If an Event of Default has occurred
and is continuing, the Trustee will use the same degree of care and skill in its
exercise

of the rights and powers vested in it under the Indenture as a prudent person
would exercise under the circumstances in the conduct of such person's own
affairs.
 
    The Indenture and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the Trustee, should it
become a creditor of the Company, to obtain payment of claims in certain cases
or to realize on certain property received by it in respect of any such claims,
as security or otherwise. The Trustee is permitted to engage in other
transactions; PROVIDED, HOWEVER, that if it acquires any conflicting interest,
it must eliminate such conflict or resign.
 
BOOK-ENTRY; DELIVERY AND FORM
 
    The certificates representing the New Notes will initially be represented by
one or more permanent global Notes in definitive, fully registered form without
interest coupons (each a "Restricted Global Note"; and together with the
Regulation S Global Note, the "Global Notes") and will be deposited with the
Trustee as custodian for, and registered in the name of a nominee of, DTC. Old
Notes sold in offshore transactions in reliance on Regulation S under the
Securities Act were initially represented by one or more temporary global Notes
in definitive, fully registered form without interest coupons (each a "Temporary
Regulation S Global Note") and were deposited with the Trustee as custodian for,
and registered in the name of a nominee of, DTC for the accounts of Euroclear
and Cedel Bank. The Temporary Regulation S Global Note is exchangeable for one
or more permanent global Notes (each a "Permanent Regulation S Global Note"; and
together with the Temporary Regulation S Global Notes, the "Regulation S Global
Note") on or after the 40th day following June 12, 1998 upon certification that
the beneficial interests in such global Note are owned by non-U.S. persons.
Prior to the 40th day after the Closing Date, beneficial interests in the
Temporary Regulation S Global Note may only be held through Euroclear or Cedel
Bank.
 
    Ownership of beneficial interests in a Global Note are limited to persons
who have accounts with DTC ("participants") or persons who hold interests
through participants. Ownership of beneficial interests in a Global Note 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 a Restricted Global Note directly through DTC if they are
participants in such system, or indirectly through organizations which are
participants in such system.
 
    Investors may hold their interests in a Regulation S Global Note directly
through Cedel Bank or Euroclear, if they are participants in such systems, or
indirectly through organizations that are participants in such systems. Cedel
Bank and Euroclear will hold interests in the Regulation S Global Notes on
behalf of their participants through DTC.
 
    So long as DTC, or its nominee, is the registered owner or holder of a
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Notes represented by such Global Note for all
purposes under the Indenture and the Notes. No beneficial owner of an interest
in a Global Note will be able to transfer that interest except in accordance
with DTC's applicable procedures, in addition to those provided for under the
Indenture and, if applicable, those of Euroclear and Cedel Bank.
 
    Payments of the principal of, and interest on, a Global Note will be made to
DTC or its nominee, as the case may be, as the registered owner thereof. Neither
the Company, the Trustee nor any Paying Agent will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in a Global Note 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 payment of
principal or interest in respect of a Global Note, will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Note as shown on the records of
 
                                      110
<PAGE>
DTC or its nominee. The Company also expects that payments by participants to
owners of beneficial interests in such Global Note 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. Transfers
between participants in Euroclear and Cedel Bank will be effected in the
ordinary way in accordance with their respective rules and operating procedures.
 
    The Company expects that DTC will take any action permitted to be taken by a
holder of Notes (including the presentation of Notes for exchange as described
below) only at the direction of one or more participants to whose account the
DTC interests in a Global Note are credited and only in respect of such portion
of the aggregate principal amount of Notes as to which such participant or
participants has or have given such direction. However, if there is an Event of
Default under the Notes, DTC will exchange the applicable Global Note for
Certificated Notes, which it will distribute to its participants and which may
be legended as set forth under the heading "Transfer Restrictions."
 
    The Company understands that DTC is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC was created to hold securities for its participants
and facilitate the clearance and settlement of securities transactions between
participants through electronic book-entry changes in accounts of its
participants, thereby eliminating the need for physical movement of certificates
and certain other organizations. 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, Euroclear and Cedel Bank are expected to follow the foregoing
procedures in order to facilitate transfers of interests in a Global Note among
participants of DTC, Euroclear and Cedel Bank, they are 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 Trustee will have any
responsibility for the performance by DTC, Euroclear or Cedel Bank or their
respective participants or indirect participants of their respective obligations
under the rules and procedures governing their operations.
 
    If DTC is at any time unwilling or unable to continue as a depositary for
the Global Notes and a successor depositary is not appointed by the Company
within 90 days, the Company will issue Certificated Notes, which may bear the
legend referred to under "Transfer Restrictions," in exchange for the Global
Notes. Holders of an interest in a Global Note may receive Certificated Notes,
which may bear the legend referred to under "Transfer Restrictions," in
accordance with DTC's rules and procedures in addition to those provided for
under the Indenture.

                     CERTAIN U.S. FEDERAL TAX CONSEQUENCES
 
    The following summary describes the material anticipated U.S. federal income
tax consequences of the purchase, ownership and disposition of the Notes. Except
where noted, it deals only with Notes held as capital assets within the meaning
of Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code"),
by U.S. holders and does not deal with special situations, such as those of
dealers in securities or currencies, financial institutions, life insurance
companies, tax exempt organizations, persons holding Notes 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 discussion below
is based upon the provisions of the Code and regulations, administrative and
judicial decisions thereunder as of the date hereof, and such authorities may be
repealed, revoked or modified with possible retroactive effect so as to result
in U.S. federal income tax consequences different from those discussed below.
 
    ALL PROSPECTIVE PURCHASERS MAY WISH TO CONSULT THEIR OWN TAX ADVISORS WITH
RESPECT TO THEIR PARTICULAR TAX SITUATION REGARDING THE FEDERAL, STATE, LOCAL
AND FOREIGN TAX CONSEQUENCES OF THE PURCHASE OWNERSHIP AND DISPOSITION OF THE
NOTES.
 
THE NEW NOTES
 
    EXCHANGE FOR REGISTERED SECURITIES.  The exchange by holder of and Old Note
for a New Note should not constitute a taxable exchange. Each New Note should be
treated as having been originally issued at the time the Old Note exchanged
therefor was originally issued.
 
    STATED INTEREST.  Each holder of Notes must include as ordinary interest
income the interest attributable to such Notes at the time it accrues or is
received, in accordance with the holder's accounting method for U.S. federal
income tax purposes.
 
    ORIGINAL ISSUE DISCOUNT.  The Notes were not issued with original issue
discount for federal income tax purposes.
 
TAX CONSEQUENCES TO U.S. HOLDERS
 
    As used herein, a "U.S. holder" means a beneficial owner that is a citizen
or resident of the U.S., a corporation, partnership or other entity created or
organized in or under the laws of 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 the administration of which is subject to
the primary supervision of a court within the U.S. and for which one or more
persons have the authority to control all substantial decisions. An individual
may, subject to certain exceptions, be deemed to be a resident (as opposed to a
non-resident alien) of the U.S. by virtue of being present in the U.S. on at
least 31 days in the calendar year and for an aggregate of at least 183 days
during a three-year period ending in the current calendar year (counting for
such purposes all of the days present in the current year, one-third of the days
present in the immediately preceding year, and one-sixth of the days present in
the second preceding year). A "Non-U.S. holder" is a holder that is not a U.S.
holder.
 
TAXATION OF INTEREST ON THE NOTES
 
    Interest paid on the Notes will be taxable to a U.S. holder as ordinary
interest income in accordance with such holder's method of tax accounting. The
Company expects that the Notes will not be issued with original issue discount
within the meaning of the Code.
 
MARKET DISCOUNT
 
    If a U.S. holder acquires a Note for an amount that is less than its
principal amount, the amount of the difference will be treated as "market
discount," unless such difference is less than a specified DE MINIMIS
 
                                      112
<PAGE>
amount. Under the market discount rules of the Code, a U.S. holder will be
required to treat any partial principal payment on, or any gain on the sale,
exchange, retirement or other disposition (including a gift) of, a Note as
ordinary income to the extent of any accrued market discount that has not
previously been included in income. Market discount generally accrues on a
straight-line basis over the remaining term of the Note, unless the U.S. holder
elects to accrue market discount on a constant interest method. A U.S. holder
may not be allowed to deduct immediately all or a portion of the interest
expense on any indebtedness incurred or continued to purchase or to carry such
Note.
 
    A U.S. holder may elect to include market discount in income currently as it
accrues (either on a straight-line basis or, if the U.S. holder so elects, on a
constant-yield basis), in which case the interest deduction deferral rule set
forth in the preceding paragraph will not apply. Such an election will apply to
all bonds acquired by the U.S. holder on or after the first day of the first
taxable year to which such election applies and may be revoked only with the
consent of the Internal Revenue Service ("IRS").
 
AMORTIZABLE BOND PREMIUM
 
    A U.S. holder that purchases a Note for an amount in excess of the principal
amount will be considered to have purchased the Note at a "premium." A U.S.
holder generally may elect to amortize such premium over the remaining term of
the Note on a constant yield method. The amount amortized in any year will be
treated as a reduction of the U.S. holder's interest income from the Note. Bond
premium on a Note 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 Note. 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 taxable year to which the
election applies and may not be revoked without the consent of the IRS.
 
SALE, EXCHANGE OR REDEMPTION OF NOTES
 
    Upon the sale, exchange or redemption or retirement of a Note, a U.S. holder
will recognize gain or loss equal to the difference between the amount realized
upon the redemption, sale, exchange or retirement and such U.S. holder's
adjusted tax basis of the Note. A U.S. holder's tax basis in a Note will, in
general, be the U.S. holder's cost therefor, increased by any market discount
previously included in income by the U.S. holder with respect to the Notes and
reduced by any principal payments on the Notes and by any amounts deducted with
respect to amortizable bond premium. Such gain or loss will be capital gain or
loss, except to the extent discussed above.
 
    The Taxpayer Relief Act of 1997 includes substantial changes to the federal
taxation of capital gains recognized by certain noncorporate taxpayers, such as
individuals, including a 20% maximum tax rate for certain gains from the sale of
capital assets held for more than 18 months. The deduction of capital losses is
subject to certain limitations.
 
    The exchange of a Note by a U.S. holder for an Exchange Note (as described
in "Description of the Notes-Registration Rights") should not constitute a
taxable exchange. A U.S. holder will have the same tax basis and holding period
in the Exchange Note as it did in the Note.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    In general, information reporting requirements will apply to certain
payments of principal and interest and to the proceeds of sales of Notes made to
U.S. holders other than certain exempt recipients (such as corporations). A 31%
backup withholding tax will apply to such payments if the U.S. holder fails (i)
to provide a taxpayer identification number ("TIN"), (ii) furnishes an incorrect
TIN, (iii) is notified by the IRS that it has failed to properly report payments
of interest and dividends or (iv) under certain circumstances, fails to certify,
under penalty of perjury, that it has furnished a correct TIN and has not been
notified by the IRS that it is subject to backup withholding. In the case of
interest paid after
 
                                      113
<PAGE>
December 31, 1999, a U.S. holder generally will be subject to backup withholding
at a 31% rate unless certain IRS certification procedures are complied with
directly or through an intermediary.
 
    The Company will furnish annually to the IRS and to record holders of the
Notes (other than with respect to certain exempt holders) information relating
to the stated interest paid or accrued during the calendar year.
 
    Any amounts withheld under the backup withholding rules generally will be
allowed as a refund or a credit against such U.S. holder's U.S. federal income
tax liability provided the required information is furnished to the IRS.
 
TAX CONSEQUENCES TO NON-U.S. HOLDERS
 
TAXATION OF INTEREST ON THE NOTES
 
    Subject to the discussion below concerning backup withholding, no
withholding of U.S. federal income tax will be required with respect to the
payment by the Company or any paying agent of principal or interest on a Note
owned by a Non-U.S. holder, provided that the beneficial owner (i) does not
actually or constructively own 10% or more of the total combined voting power of
all classes of stock of the Company entitled to vote within the meaning of
Section 871(h)(3) of the Code and the regulations thereunder, (ii) is not a
controlled foreign corporation related, directly or indirectly, to the Company
through stock ownership, (iii) is not a bank whose receipt of interest on a Note
is described in Section 881(c)(3)(A) of the Code and (iv) satisfies the
statement requirement (described generally below) set forth in Section 871(h)
and Section 881(c) of the Code and the regulations thereunder.
 
    To satisfy the requirement referred to in (iv) above, the beneficial owner
of such Note, or a financial institution holding the Note on behalf of such
owner, must provide, in accordance with specified procedures, the Company or its
paying agent with a statement to the effect that the beneficial owner is not a
U.S. person. These requirements will be met if (x) the beneficial owner provides
his name and address, and certifies, under penalties of perjury, that he is not
a U.S. person (which certification may be made on an IRS Form W-8 (or successor
form)) or (y) a financial institution holding the Note on behalf of the
beneficial owner certifies, under penalties of perjury, that such statement has
been received by it and furnishes a paying agent with a copy thereof.
 
    In the event that any of the above requirements are not satisfied, the
Company will nonetheless not withhold federal income tax on interest paid to a
Non-U.S. holder if it receives IRS Form 4224 (or, after December 31, 1999, a
Form W-8) from such Non-U.S. holder, establishing that such income is
effectively connected with the conduct of a trade or business in the U.S.,
unless the Company has knowledge to the contrary. Interest or redemption premium
paid to a Non-U.S. holder that is effectively connected with the conduct by the
holder of a trade or business in the U.S. is generally taxed at the graduated
rates that are applicable to U.S. holders. In the case of a Non-U.S. holder that
is a corporation, such effectively connected income may also be subject to the
U.S. federal branch profits tax (which is generally imposed on a foreign
corporation on the deemed repatriation from the U.S. of effectively connected
earnings and profits) at a 30% rate (unless the rate is reduced or eliminated by
an applicable income tax treaty and the holder is a qualified resident of the
treaty country).
 
SALE, EXCHANGE, OR REDEMPTION OF NOTES
 
    A Non-U.S. holder will generally not be subject to U.S. federal income tax
with respect to capital gain recognized on a sale, exchange, redemption or other
disposition of Notes unless (i) the gain is effectively connected with a trade
or business of the Non-U.S. holder in the U.S., (ii) in the case of a Non-U.S.
holder who is an individual, such holder is present in the U.S. for 183 or more
days in the taxable year of the sale or other disposition and certain other
conditions are met, or (iii) the Non-U.S. holder is subject to tax pursuant to
certain provisions of the Code applicable to U.S. expatriates.
 
                                      114
<PAGE>
    Gains derived by a Non-U.S. holder from the sale or other disposition of
Notes that are effectively connected with the conduct by the holder of a trade
or business in the U.S. are generally taxed at the graduated rates that are
applicable to U.S. holders. In the case of a Non-U.S. holder that is a
corporation, such effectively connected income may also be subject to the U.S.
branch profits tax (which is generally imposed on a foreign corporation on the
deemed repatriation from the United States of effectively connected earnings and
profits) at a 30% rate (unless the rate is reduced or eliminated by an
applicable income tax treaty and the holder is a qualified resident of the
treaty country).
 
FEDERAL ESTATE TAX
 
    A Note beneficially owned by an individual who at the time of death is a
Non-U.S. holder will not be subject to U.S. federal estate tax as a result of
such individual's death, provided that such individual does not actually or
constructively own 10% or more of the total combined voting power of all classes
of stock of the Company entitled to vote within the meaning of Section 871(h)(3)
of the Code and provided that the interest payments with respect to such Note
would not have been, if received at the time of such individual's death,
effectively connected with the conduct of a U.S. trade or business by such
individual.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    No information reporting or backup withholding will be required with respect
to payments made by the Company or any paying agent to Non-U.S. holders if a
statement described in (iv) under "Tax Consequences to Non-U.S.
Holders--Taxation of Interest on the Notes" has been received and the payor does
not have actual knowledge that the beneficial owner is a U.S. person.
 
    Information reporting and backup withholding will not apply if payments of
interest on a Note are made outside the U.S. to an account maintained at an
office or branch of a U.S. or foreign bank or other financial institution,
provided certain procedures are in place and are observed.
 
    Payments on the sale, exchange or other disposition of a Note made to or
through a foreign office of a broker generally will not be subject to backup
withholding. However, payments made by a broker that is a U.S. person, a
controlled foreign corporation for U.S. federal income tax purposes, a foreign
person 50% or more of whose gross income is effectively connected with a U.S.
trade or business for a specified three year period, or (with respect to
payments after December 31, 1999) a foreign partnership with certain connections
to the U.S., will be subject to information reporting unless the broker has in
its records documentary evidence that the beneficial owner is not a U.S. person
and certain other conditions are met, or the beneficial owner otherwise
establishes an exemption. Backup withholding may apply to any payment that such
broker is required to report if the broker has actual knowledge that the payee
is a U.S. person. Payments to or through the U.S. office of a broker will be
subject to information reporting and backup withholding unless the holder
certifies, under penalties of perjury, that it is not a U.S. person or otherwise
establishes an exemption.
 
    Non-U.S. holders should consult their tax advisors regarding the application
of information reporting and backup withholding in their particular situations,
the availability of an exemption therefrom, and the procedures for obtaining
such an exemption, if available. Any amounts withheld under the backup
withholding rules generally will be allowed as a refund or credit against the
Non-U.S. holder's U.S. federal income tax liability and may entitle such holder
to a refund, provided the required information is furnished to the IRS.
 
                                      115
<PAGE>
                              PLAN OF DISTRIBUTION
 
    There has previously been only a limited secondary market and no public
market for the Old Notes. The Company does not intend to apply for the listing
of the Notes on a national securities exchange or for their quotation through
The Nasdaq Stock Market. The Notes are eligible for trading in the PORTAL
market. The Company has been advised by the Placement Agents that the Placement
Agents currently intend to make a market in the Notes; however, no Placement
Agent is 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 Notes or the New Notes will develop. If a trading
market does not develop or is not maintained, holders of Notes may experience
difficulty in reselling Notes. If a trading market develops for the Notes,
future trading prices of such securities will depend on many factors, including,
among other things, prevailing interest rates, the Company's results of
operations and the market for similar securities. Depending on such factors,
such securities may trade at a discount from their offering price.
 
    BROKER-DEALERS WHO DID NOT ACQUIRE OLD NOTES AS A RESULT OF MARKET MAKING
ACTIVITIES OR TRADING ACTIVITIES MAY NOT PARTICIPATE IN THE EXCHANGE OFFER.
 
    With respect to resale of New Notes, based on an interpretation by the staff
of the Commission set forth in no-action letters issued to third parties, the
Company believes that a holder (other than a person that is an affiliate of the
Company within the meaning of Rule 405 under the Securities Act or a "broker" or
"dealer" registered under the Exchange Act) who exchanges Old Notes for New
Notes in the ordinary course of business and who is not participating, does not
intend to participate, and has no arrangement or understanding with any person
to participate, in the distribution of the New Notes, will be allowed to resell
the New Notes to the public without further registration under the Securities
Act and without delivering to the purchasers of the New Notes a prospectus that
satisfies the requirements of Section 10 thereof. However, if any holder
acquires New Notes in the Exchange Offer for the purpose of distributing or
participating in a distribution of the New Notes, such holder cannot rely on the
position of the staff of the Commission enunciated in EXXON CAPITAL HOLDINGS
CORPORATION (available May 13, 1988) or similar no-action letters or any similar
interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with a secondary
resale transaction, unless an exemption from registration is otherwise
available.
 
    As contemplated by the no-action letters mentioned above and the
Registration Rights Agreement, each holder accepting the Exchange Offer is
required to represent to the Company in the Letter of Transmittal that (i) the
New Notes are to be acquired by the holder in the ordinary course of business,
(ii) the holder is not engaging and does not intend to engage in the
distribution of the New Notes, and (iii) the holder acknowledges that, if such
holder participates in the Exchange Offer for the purpose of distributing the
New Notes, such holder must comply with the registration and prospectus delivery
requirements of the Securities Act and cannot rely on the above no-action
letters.
 
    Any broker or dealer registered under the Exchange Act (each a
"Broker-Dealer") who holds Old Notes that were acquired for its own account as a
result of market-making activities or other trading activities (other than Old
Notes acquired directly from the Company or an affiliate of the Company) may
exchange such Old Notes for New Notes pursuant to the Exchange Offer; however,
such Broker-Dealer may be deemed an underwriter within the meaning of the
Securities Act and, therefore, must deliver a prospectus meeting the
requirements of the Securities Act in connection with any resales of the New
Notes received by it in the Exchange Offer, which prospectus delivery
requirement may be satisfied by the delivery by such Broker-Dealer of this
Prospectus. The Company has agreed to cause the Exchange Offer Registration
Statement, of which this Prospectus is a part, to remain continuously effective
for a period of 180 days, if required, from the Exchange Date, and to make this
Prospectus, as amended or supplemented, available to any such Broker-Dealer for
use in connection with resales. Any Broker-Dealer participating in
 
                                      116
<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 Notes received by it in the Exchange Offer. The delivery by a
Broker-Dealer of a prospectus in connection with resales of New Notes shall not
be deemed to be an admission by such Broker-Dealer that it is an underwriter
within the meaning of the Securities Act. The Company will not receive any
proceeds from any sale of New Notes by a Broker-Dealer.
 
    New Notes received by Broker-Dealers for their own account pursuant to the
Exchange Offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the New Notes or a combination of such methods of resale, at market
prices prevailing at the time of resale, at prices related to such prevailing
market prices or negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such Broker-Dealer and/or the
purchasers of any such New Notes.
 
                                 LEGAL MATTERS
 
    Certain legal matters with respect to the validity of the Notes are being
passed upon for the Company by McAfee & Taft A Professional Corporation,
Oklahoma City, Oklahoma.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of
Logix Communications Enterprises, Inc.:
 
    We have audited the accompanying consolidated balance sheets of Logix
Communications Enterprises, Inc. (formerly named Dobson Wireline Company) (an
Oklahoma corporation) and subsidiaries as of December 31, 1996 and 1997, and the
related consolidated statements of operations, stockholder's equity 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 consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Logix Communications Enterprises, Inc. 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:
 
    Logix Communications Enterprises, Inc. (formerly named Dobson Wireline
Company) ("Logix") was incorporated as an Oklahoma corporation in December 1997
as part of a reorganization by its parent company, Dobson Communications
Corporation ("Dobson Communications"). Logix and its subsidiaries are referred
to herein as the "Company." Logix is a wholly owned subsidiary of Dobson
Communications that provides, through its subsidiaries, voice, data and Internet
services to residential, business, government and other institutional users in
Oklahoma, Texas and Colorado. The Company provides these services through three
business segments: incumbent local exchange carrier ("ILEC") operations, fiber
optic telecommunications and integrated communications provider ("ICP")
operations. The consolidated financial statements of the Company include the
accounts of Logix, Dobson Telephone Company, Inc. ("Dobson Telephone"), Dobson
Fiber Company, Inc. ("Dobson Fiber"), Dobson Fiber/FORTE of Colorado, Inc.,
Logix Communications Corporation ("LCC") and Dobson Network Management, Inc.
collectively referred to herein as the "Subsidiaries."
 
    REORGANIZATION OF DOBSON COMMUNICATIONS
 
    In January 1998, Dobson Communications transferred all of the common stock
of the Subsidiaries to . The transaction was considered a reorganization of
entities under common control under which the accounting treatment of the
reorganization is similar to a pooling-of-interests.
 
    Concurrent with the reorganization, the number of shares and par value of
the Company's authorized stock changed. All share and per share data are stated
to reflect the common stock changes.
 
    The effects of all intercompany transactions between the Company and its
subsidiaries prior to the reorganization have been eliminated.
 
    CAPITAL RESOURCES AND GROWTH
 
   
    The Company's total indebtedness and debt service requirements will
substantially increase as a result of the transactions described in Note 13, and
the Company will be subject to significant financial restrictions and
limitations. If the Company is unable to borrow sufficient funds through the
bridge facility or the senior notes described in Note 13, the Company may be
unable to borrow additional funds from other sources during such time period to
fund planned capital expenditures, its ongoing operations or other permissible
uses.
    
 
    The Company's ability to manage future growth will depend upon its ability
to monitor operations, control costs, maintain effective quality controls and
significantly expand the Company's internal management, technical and accounting
systems, all of which will result in higher operating expenses. Any failure to
expand these areas and to implement and improve such systems, procedures and
controls in an efficient manner at a pace consistent with the growth of the
Company's business could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
    ILEC
 
    The Company, through Dobson Telephone, provides wireline telephone service
to nine contiguous exchanges in western Oklahoma and three contiguous exchanges
adjacent to and east of the Oklahoma City metropolitan area. Dobson Telephone
operates under the authority of the Federal Communications Commission ("FCC").
Rates charged by Dobson Telephone are regulated by the FCC and the Oklahoma
Corporation Commission. Dobson Telephone, like other wireline companies that
operate in rural areas where the cost to provide service is higher than normal,
receives high cost support funds from state jurisdictions and the federal
universal service fund. Approximately 31%, 36% and 36% of the Company's
 
                                      F-7

1. ORGANIZATION: (CONTINUED)
revenue from its ILEC operations for the year ended December 31, 1995, 1996 and
1997, respectively, was from these two sources.
 
    FIBER OPTIC TELECOMMUNICATIONS
 
   
    The Company provides fiber optic telecommunications service between Oklahoma
City, Oklahoma and Amarillo, Texas through Dobson Fiber. In addition, the
Company has a 20% interest in and manages the FORTE of Colorado Partnership
which provides fiber optic telecommunication service between Springfield,
Colorado and Colorado Springs, Colorado (See Note 10).
    
 
    ICP
 
    The Company commenced its ICP operations in October 1997 through its
subsidiary, LCC. LCC provides facilities based and resells integrated services
including local exchange, long distance, data, wireless, paging and Internet in
Oklahoma City and Tulsa, Oklahoma. Until October 1997, LCC's principal
activities included developing its business plans, procuring governmental
authorizations, hiring management and other key personnel, working on the design
and development of its competitive local exchange telephone networks and
operations support systems ("OSS"), acquiring equipment and facilities and
negotiating interconnection agreements. Accordingly, Logix has incurred
operating losses and operating cash flow deficits.
 
    LCC's success will be affected by the problems, expenses, and delays
encountered in connection with the formation of a new business, and the
competitive environment in which LCC intends to operate. LCC's performance will
further be affected by its ability to assess potential markets, secure financing
or raise additional capital, implement expanded interconnection and collocation
with ILEC facilities, lease adequate trunking capacity from ILECs or other ICPs,
purchase and install switches in additional markets, expand or replace its OSS
and other back office systems, develop a sufficient customer base, and attract,
retain, and motivate qualified personnel. LCC's networks and telecommunications
services are subject to significant regulation at the federal, state and local
levels. Delays in receiving required regulatory approvals or the enactment of
new adverse regulation or regulatory requirements may have a material adverse
effect upon LCC. Although management believes that LCC will be able to
successfully mitigate these risks, there is no assurance that LCC will be able
to do so or that LCC will ever operate profitably. Expenses are expected to
exceed revenues in each location in which LCC offers service until sufficient
customer base is established.
 
   
    On March 26, 1998, Logix entered into a definitive agreement to purchase
substantially all of the assets of American Telco, Inc. and American Telco
Network Services, Inc. (collectively, "ATI") for $130 million, subject to
adjustment, as discussed in Note 13.
    
 
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
consolidates each subsidiary and partnership in which it has a controlling
interest. 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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents on the accompanying consolidated balance sheets
includes cash and short-term investments with original maturities of three
months or less.
 
    INVENTORY
 
    The Company values its inventory at the lower of cost or market on the
first-in, first-out method of accounting.
 
    IMPAIRMENT OF LONG-LIVED ASSETS
 
    The Company assesses potential impairments of long-lived assets, certain
identifiable intangibles and excess of cost over original cost of assets
acquired 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.
 
    DEFERRED COSTS
 
    Deferred costs consist primarily of fees incurred to secure long-term debt
and start-up 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 $8,694, $3,622 and $163,510 was recorded in
1995, 1996 and 1997, respectively. As discussed in Note 12, the Company wrote
off its deferred start-up costs effective January 1, 1998.
 
    EXCESS OF COST OVER ORIGINAL COST OF ASSETS ACQUIRED
 
   
    The excess of cost over the original cost of assets acquired relates to
Dobson Telephone's acquisition of McLoud Telephone Company in 1985 and is being
amortized using the straight-line method over 40 years. Amortization expense of
$95,240 was recorded in 1995, 1996 and 1997. As the excess cost over original
cost of assets acquired is a term defined and required by regulatory accounting
practices applicable to Dobson Telephone, such amounts are presented separately
from amounts included in the caption "Goodwill."
    
 
    ADVERTISING COSTS
 
    Advertising costs are expensed as incurred and are included as selling,
general and administrative expenses in the accompanying consolidated statements
of operations. Advertising expense of $3,866, $7,877 and $221,473 was incurred
in 1995, 1996 and 1997.
 
    INCOME TAXES
 
    The Company files a consolidated income tax return with its parent, Dobson
Communications. 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 temporary differences between
financial statement and tax bases of assets and liabilities at year-end. Amounts
owed to Dobson Communications for income taxes are reflected in
receivables-affiliates and deferred credits in the accompanying balance sheets.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    REVENUE RECOGNITION
 
    The Company records service revenues over the period they are earned. The
cost of providing service is recognized as incurred.
 
    Toll revenue is billed in arrears. The Company accrued estimated unbilled
revenues for services provided of approximately $277,000 and $271,000 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 in deferred revenue and customer
deposits on the accompanying consolidated balance sheets.
 
    EARNINGS PER SHARE
 
    Basic net income per common share is computed by using the weighted average
number of shares of common stock outstanding during the year. In 1997, the
Company adopted SFAS No. 128, "Earnings Per Share" which did not change the
Company's reported net income per common share for 1995 and 1996. The Company
has not presented diluted earnings per share as it has no potentially dilutive
securities.
 
    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.
 
    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 will 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, consisting of
both net income and those items that bypass the statement of operations and are
reported as a separate component of stockholder's equity, 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
through December 31, 1997 will differ materially from net income.
 
    At December 31, 1997, the Company adopted SFAS No. 131, "Disclosure about
Segments of an Enterprise and Related Information," which requires a new basis
of determining reportable segments (i.e., the management approach). This
approach (as contrasted with the prior requirement which utilized a specified
classification system for determining segments) designates the Company's
internal organization as used by management for making operating decisions and
assessing performance as the source of business segments. The Company is
organized into three business segments to facilitate the delivery of service to
customers: ILEC, Fiber and ICP. Segment results are presented on this new basis
in Note 9 at December 31, 1995, 1996 and 1997.
 
3. PROPERTY, PLANT AND EQUIPMENT:
 
    Property, plant and equipment are recorded at cost. Newly constructed
telephone systems and fiber optic cable 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 significant. 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 Dobson Communications' bank credit agreement was
amended and restated to provide Dobson Communications with a $200 million
revolving credit facility maturing in 2005. Interest on borrowings under this
credit agreement accrues at variable rates (weighted average rate of 8.43% at
December 31, 1997). The Company's portion of the initial proceeds were used to
refinance existing indebtedness, and for general corporate purposes. 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 $351,000 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.
 
    Effective December 31, 1997, Dobson Communications made a capital
contribution to the Company of approximately $11,447,000, which represented the
Company's outstanding portion of the revolving credit facility payable to Dobson
Communications.

    The mortgage notes payable to the United States of America, through the
Rural Utilities Service ("RUS") and the Rural Telephone Bank ("RTB") with
interest rates ranging from 2% to 10.75% due in quarterly or monthly
installments maturing at various dates from 1998 to 2028. The mortgage notes are
secured by substantially all the assets of Dobson Telephone and contain, among
other things, restrictions on the payment of dividends and redemption of capital
stock, as defined. Under the long-term debt agreements, Dobson Telephone is
restricted, without RUS approval for Dobson Telephone, from making any loans to,
or in any manner extending its credit to various affiliates. The agreements also
prohibit payment of dividends or distributions or new investments in affiliated
companies unless after such action Dobson Telephone's current assets exceed its
current liabilities and its adjusted net worth (as defined in the agreement) is
at least 40% of (i) its adjusted assets (as defined in the agreement), or, (ii)
if smaller, the sum of 10% of its adjusted assets, plus 30% of the excess of its
adjusted net worth over 10% of its adjusted assets, if any, plus 30% of the
amount of any reduction of its adjusted net worth resulting from the declaration
or payment of dividends or other distributions.

7. RELATED PARTY TRANSACTIONS:
 
   
    Beginning in 1997, Dobson Communications began to provide certain
administrative services, including accounting, information systems management,
human resource management and marketing. Additionally, officers of the Company
are also officers of Dobson Communications and various of its other
subsidiaries. These officers perform functions for all of Dobson Communications,
including the Company. The Company reimburses Dobson Communications based on
Dobson Communications' cost of providing the services. Dobson Communications
allocates these costs based on the subsidiaries' usage of corporate services.
Management of the Company believes this is the most reasonable method to
allocate such costs. The total amount charged to the Company for these
administrative services and officer compensation was $2,345,000, $3,245,000 and
$2,644,000 in 1995, 1996 and 1997, respectively. Management believes these costs
would not have been significantly different had the costs been incurred directly
by the Company.
    
 
    The Company had receivables from Dobson Communications and certain of its
subsidiaries totaling $11,514,356 and $8,206,935 at December 31, 1996 and 1997,
respectively. These receivables represent advances to these entities net of
repayments and intercompany allocations. The net receivables from these
affiliates have been reflected as receivables-affiliates in the accompanying
balance sheets.
 
    The Company carries telephone traffic and provides network monitoring for
affiliated companies of Dobson Communications. Fees of approximately $1,658,000
and $1,722,000 were earned from the affiliated companies for services provided
during 1996 and 1997, respectively, and are reflected in revenue in the
accompanying statements of operations.

9. REPORT OF BUSINESS SEGMENTS:
 
   
    The Company operates in three reportable segments: ILEC, Fiber and ICP.
These segments are strategic business units that offer different products and
services. The segments are managed separately because each business requires
different technology and marketing strategies. The accounting policies of the
segments are the same as those described in the summary of significant
accounting policies in Note 2. The Company evaluates and measures performance of
each segment based on Adjusted EBITDA, which is defined in Note (2) on p. F-16,
and income (loss) before income taxes, extraordinary items and cumulative effect
of changes in accounting principle. The Company accounts for intersegment sales
and transfers as if the sales or transfers were to third parties, that is, at
current market prices. The Company allocates corporate overhead, income taxes
and amortization of deferred financing cost to each segment. The segments do not
have significant noncash items other than depreciation and amortization in
reported profit or loss. A summary of the Company's operations by segment is as
follows:

13. SUBSEQUENT EVENTS:
    
 
    PENDING ACQUISITIONS
 
    On March 26, 1998, Logix entered into a definitive agreement to purchase the
stock of ATI for $130 million, subject to adjustment. ATI is based in Houston,
Texas and provides resale services primarily to business customers in five major
Texas markets, including Houston, Dallas, Ft. Worth, San Antonio and Austin. At
the time of the agreement, the Company placed $5 million into an escrow account
pending closing. Logix plans to finance the acquisition through the issuance of
senior notes.
 
    On January 6, 1998, a subsidiary of the Company purchased from previously
assigned Zenex Communications, Inc. ("Zenex") contractual rights, information,
data and other rights with respect to certain of Zenex's long distance customers
located in areas served by Dobson Telephone for $105,000.
 
    ZENEX
 
    On April 7, 1998, the Company entered into a non-binding letter of intent
with Zenex to purchase certain long distance customers and related assets of
Zenex, excluding Zenex's switch and the assets relating to Zenex's prepaid long
distance cards, for $500,000 and the assumption of certain liabilities of Zenex.
 
    ACCOUNTING PRONOUNCEMENTS
 
    In March, 1998, the Accounting Standards Executive Committee ("AcSEC")
issued Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use," effective for fiscal years
beginning after December 15, 1998. The Company adopted SOP 98-1 as of January 1,
1998. It requires capitalization of the development costs of software to be used
internally (e.g. administrative processes). The adoption of this SOP did not
materially impact the Company's net income.
 
    In April 1998, the AcSEC issued SOP 98-5, "Reporting on the Costs of
Start-Up Activities," effective for fiscal years beginning after December 15,
1998. The Company adopted this SOP as of January 1, 1998. SOP 98-5 requires
costs of start-up activities and organization costs to be expensed as incurred.
The Company will recognize a pretax loss of approximately $1,128,000 as
cumulative effect of accounting change as a result of adopting this SOP.
 
    RECAPITALIZATION
 
    On September 30, 1998, the Company approved its Amended and Restated
Certificate of Incorporation, which increased the number of authorized shares of
capital stock to 100,000,000. The Company also approved a stock split on the
same date increasing the number of outstanding shares of common stock to
71,250,000. The accompanying financial statements have been retroactively
restated to reflect this stock split. In addition, on September 30, 1998, the
Company approved a stock option plan covering 3,750,000 shares of common stock,
of which the Company granted options covering 1,417,500 shares of common stock
to employees at an option price of $2 per share.

was changed to Logix Communications Enterprises, Inc. in October 1998. is a
wholly owned subsidiary of Dobson Communications that provides, through its
subsidiaries, voice, data and Internet services to residential, business,
government and other institutional users in Oklahoma, Texas and Colorado. The
Company provides these services through three business segments: incumbent local
exchange carrier ("ILEC") operations, fiber optic telecommunications operations
and integrated communications provider ("ICP") operations. The consolidated
financial statements of the Company include the accounts of Logix Communications
Enterprises, Inc., Dobson Telephone Company, Inc. ("Dobson Telephone"), Dobson
Fiber Company, Inc. ("Dobson Fiber"), Dobson Fiber/ FORTE of Colorado, Inc.,
Logix Communications Corporation ("LCC"), American Telco, Inc. ("ATI") and
Dobson Network Management, Inc. collectively referred to herein as the
"Subsidiaries."
 
    REORGANIZATION OF DOBSON COMMUNICATIONS
 
    In January, 1998, Dobson Communications transferred all of the common stock
of the Subsidiaries, excluding ATI, to Logix. The transaction was considered a
reorganization of entities under common control under which the accounting
treatment of the reorganization is similar to a pooling-of-interests.
 
    Concurrent with the reorganization, the number of shares and par value of
the Company's authorized stock changed. All share and per share data are stated
to reflect the common stock changes.
 
    The effects of all intercompany transactions, including the transactions
prior to the reorganization, have been eliminated.
 
2. ACQUISITIONS
 
    On March 26, 1998, the Company entered into a definitive agreement to
purchase the common stock of ATI for $131.5 million. ATI is based in Houston, TX
and provides telecommunications services to customers in five major Texas
markets, including Houston, Dallas, Fort Worth, San Antonio and Austin. The
Company closed this acquisition on June 15, 1998, using the proceeds from the
debt offering described in Note 6.

3. RESTRICTED CASH AND INVESTMENTS
 
    Restricted cash and investments consist of an interest pledge deposit, net
of premium, of approximately $121 million to fund the first six semi-annual
interest payments which begin on December 15, 1998.
 
    Investments that will mature within the next year and will be used to
satisfy interest payments then due, have been classified as a current asset on
the accompanying condensed consolidated balance sheet at June 30, 1998.
 
4. EARNINGS PER COMMON SHARE
 
    Basic income (loss) per common share is computed by using the weighted
average number of shares of common stock outstanding during the year. Diluted
net loss per common share has been omitted because the Company has no
potentially dilutive securities.
 
5. RECENT PRONOUNCEMENTS
 
    In March, 1998, the Accounting Standards Executive Committee ("AcSEC")
issued Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use," effective for fiscal years
beginning after December 15, 1998. The Company adopted SOP 98-1 as of January 1,
1998. It requires capitalization of the development costs of software to be used
internally (e.g. administrative processes). The adoption of this SOP did not
materially impact the Company's net income.
 
    In April, 1998, the AcSEC issued SOP 98-5, "Reporting on the Costs of
Start-Up Activities," effective for fiscal years beginning after December 15,
1998. 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.
The Company has recognized a pretax loss of approximately $1.1 million as a
result of adopting this SOP. This loss has been reflected as a cumulative effect
of change in accounting principle, net of tax, in the accompanying condensed
consolidated statement of operations.
 
6. SENIOR NOTES
 
    On June 12, 1998, the Company sold $350 million of 12 1/4% senior notes due
2008. A portion of the proceeds were used to close the ATI Acquisition and
purchase approximately $121 million of securities to be held in escrow to pay
the first six scheduled semi-annual interest payments on the Company's Senior
Notes. See Note (3).

7. REPORT OF BUSINESS SEGMENTS
 
   
    The Company operates in three reportable segments: ILEC, Fiber and ICP.
These segments are strategic business units that offer different products and
services. They are managed separately because each business requires different
technology and marketing strategies. The accounting policies of the segments are
the same as those of the Company. The Company evaluates and measures performance
of each segment based on Adjusted EBITDA, which is defined in Note (2) on page
F-25, and income (loss) before income taxes, extraordinary items and cumulative
effect of change in accounting principles. The Company accounts for intersegment
sales and transfers as if the sales or transfers were to third parties, that is,
at current market prices. The Company allocates corporate overhead, income taxes
and amortization of deferred financing cost to each segment. The segments do not
have significant non-cash items other than depreciation and amortization in
reported profit or loss. A summary of the Company's operations by segment is as
follows:

To the Board of Directors and Shareholders of
American Telco, Inc. and American Telco Network Services, Inc.
 
    In our opinion, the accompanying combined balance sheets and the related
combined statements of income, of shareholders' equity and of cash flows present
fairly, in all material respects, the financial position of American Telco, Inc.
and American Telco Network Services, Inc. (the Companies) at December 31, 1996
and 1997, and the results of their operations and their cash flows for each of
the three years ended December 31, 1997 in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Companies' management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BUSINESS COMBINATION
 
    The companies included in the accompanying combined financial statements,
American Telco, Inc. (ATI) and American Telco Network Services, Inc. (ATNSI)
(collectively, the Companies), are under common control. All material
intercompany transactions and profits or losses have been eliminated in these
combined financial statements.
 
    ATI and ATNSI were incorporated in Texas on May 12, 1983 and December 29,
1986, respectively. ATI is a provider of local and long distance telephone
services and ATNSI provides related telecommunication services. In 1997, ATI
began to provide local telephone service to commercial customers in certain
major Texas cities. Local service revenues were less than 10% of total revenues
during 1997.
 
    REVENUE RECOGNITION
 
    The Companies use the accrual method in recognizing telephone service income
when service is provided. Expenses associated with the cost of
telecommunications are accrued when service is used. Management believes the
Companies are not subject to significant concentrations of credit risk due to
the diverse nature of their customer base.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost and depreciated using the
straight-line method over their estimated useful lives; leasehold improvements
are amortized using the straight-line method over the lease term or the
estimated useful life of the related assets, whichever is shorter.
 
    LONG-LIVED ASSETS
 
    In accordance with Statement of Financial Accounting Standards No. 121 (FAS
121) "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of," the Companies review for the impairment of long-lived
assets and certain identifiable intangibles on a periodic basis and whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. Under FAS 121, an impairment loss would be recognized
when estimated future cash flows expected to result from the use of the asset
and its eventual disposition is less than its carrying amount. No such
impairment losses have been identified by the Companies through December 31,
1997.
 
    INCOME TAXES
 
    The Companies have elected to be treated as S Corporations for federal
income tax purposes. As such, no provision for federal income taxes has been
presented in these combined financial statements since taxes are to be paid by
the shareholders individually. In 1997 certain costs amounting to approximately
$1,000,000 have been capitalized for financial reporting purposes that will be
expensed as incurred for tax purposes.
 
    CASH EQUIVALENTS
 
    The Companies consider all temporary cash investments purchased with an
original maturity of three months or less to be cash equivalents.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    CAPITALIZED COSTS
 
    Effective January 1, 1997, the Companies adopted the policy of capitalizing
costs incurred to increase the capacity of their telecommunications network.
Such costs were previously expensed as incurred. During 1997, the Companies
incurred and capitalized $257,000 related to network capacity upgrades. These
costs are included in other assets and are amortized using the straight-line
method over a period of four years. Management believes the impact on the
Companies' financial position and results of operations resulting from this
change in accounting principles is not material.
 
    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 reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements, as well as the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. Management
believes the estimates and assumptions used in the preparation of these
financial statements are reasonable.

    The Companies have capitalized $760,003 during 1997 of internal costs
related to the development of new customer service, local service, line charge
reconciliation and billing softwares developed during the year. This amount is
included in furniture and equipment at December 31, 1997.
 
3. INDEBTEDNESS
 
    In September 1996, ATI entered into a credit agreement with a financial
institution. The credit agreement provides for an aggregate of $3,500,000 in
borrowings under a line of credit and under letters of credit. Borrowings under
the line of credit may not exceed 80% of eligible accounts receivable, and
letters of credit outstanding may not exceed $1,000,000. Advances bear interest
at prime, with an adjusted LIBOR rate option, and are secured by accounts
receivable, contract rights, deposit accounts and general intangibles. At
December 31, 1997, the outstanding balance under this facility was $853,000.
Maximum borrowings outstanding under the line of credit were $3,426,000 during
1997.

               NOTES TO CONDENSED COMBINED FINANCIAL INFORMATION
 
                                 MARCH 31, 1998
 
                                  (UNAUDITED)
 
    The condensed combined balance sheets of American Telco, Inc. and American
Telco Network Services, Inc. as of December 31, 1997 and March 31, 1998, the
condensed combined statements of operations for the three months ended March 31,
1997 and 1998, the combined statement of shareholders equity for the year ended
December 31, 1997 and the three months ended March 31, 1998, and the condensed
combined statements of cash flows for the three months ended March 31, 1997 and
1998 are unaudited. They do not include all information and notes required by
generally accepted accounting principles for complete financial statements. In
the opinion of management, such financial statements include all adjustments,
consisting only of normal recurring adjustments necessary for a fair
presentation of financial position, results of operations, and cash flows for
the periods presented.
 
    The condensed combined 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 Companies' December 31, 1997
combined financial statements.
 
1. BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
    The companies included in the accompanying combined financial statements,
American Telco, Inc. (ATI) and American Telco Network Services, Inc. (ATNSI)
(collectively, the Companies), are under common control. All material
intercompany transactions and profits and losses have been eliminated in these
combined financial statements.
 
    ATI and ATNSI were incorporated in Texas on May 12, 1983 and December 29,
1986, respectively. ATI is a provider of local and long distance telephone
services and ATNSI provides related telecommunication services. In 1997, ATI
began to provide local telephone service to commercial customers in certain
major Texas cities. Local service revenues were less than 1% and approximately
10% of total revenues during the three months ended March 31, 1997 and 1998,
respectively.
 
    REVENUE RECOGNITION
 
    The Companies use the full accrual method in recognizing telephone service
income when service is provided. Expenses associated with the cost of
telecommunications are accrued when service is used. Management believes the
Companies are not subject to significant concentrations of credit risk due to
the diverse nature of their customer base.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost and depreciated using the
straight-line method over their estimated useful lives; leasehold improvements
are amortized using the straight-line method over the lease term or the
estimated useful life of the related assets, whichever is shorter.
 
    INCOME TAXES
 
    The Companies have elected to be treated as S Corporations for federal
income tax purposes. As such, no provision for federal income taxes has been
presented in those combined financial statements since income taxes are to be
paid by the shareholders individually.

                                  (UNAUDITED)
 
2. INDEBTEDNESS
 
    In September 1996, ATI entered into a credit agreement with a financial
institution. The credit agreement provided for an aggregate of $3,500,000 in
borrowings under a line of credit and under letters of credit. During the three
months ended March 31, 1998, the line of credit was increased to $7,000,000.
Borrowings under the line of credit may not exceed 80% of eligible accounts
receivable and letters of credit outstanding may not exceed $1,000,000. Advances
bear interest at prime, with an adjusted LIBOR rate option, and are secured by
accounts receivable, contract rights, deposit accounts and general intangibles.
At March 31, 1998, the outstanding balance under this facility was $878,000.
 
    At March 31, 1998, ATI had a long-term loan amounting to $393,589. The loan
bears interest at prime. Payments are made monthly and include $8,731 in
principal and related interest accruing during the month. The term of the loan
is 60 months starting in December 1997.
 
    These agreements require that certain restrictive and minimum financial
covenants be maintained.
 
    The Company also have received advances from certain officers/shareholders.

                     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, 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 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.
