                                  OUR COMPANY


    We are a rapidly growing integrated communications provider. We seek to
become the leading provider of telecommunications services for small and
mid-sized businesses in each of the cities we serve. We offer state-of-the-art
telecommunications services to our customers, who today are located throughout
Missouri, Kansas, Texas and Oklahoma. These voice and data service offerings
include local and long distance telephone service, Internet access, web hosting,
integrated voice and data transmission over broadband lines and customer
premises equipment sales and services. We offer these services to our customers
through a combination of leased and owned network facilities. We are currently
deploying collocations and transmission equipment throughout our markets to
deliver digital subscriber line service, which will support dedicated high-speed
Internet access and eventually voice services. We expect to have over 130
collocations operational by the end of this year. Our revenue for the year ended
December 31, 1999 was $60.5 million, a 132% increase over 1998 and was
$23.8 million for the quarter ended March 31, 2000, a 124% increase over the
equivalent period in 1999.



    We have increased our local access lines in service to over 168,000 and now
serve over 29,000 business customers, making us one of the largest integrated
communications providers in the territory served by Southwestern Bell. We intend
to continue to grow our customer base rapidly. We currently serve 23 markets
that have populations ranging in size from 95,000 to 4.5 million. We average
7,000 lines in each of those markets. We intend to offer our services in an
additional 35 markets before the end of 2001. We expect to commence service in
the regions served by Ameritech and BellSouth in 2001. We have developed systems
and network capabilities and have an experienced sales force and customer
service team that position us to rapidly penetrate new markets and serve a
growing number of customers. We believe that our success to date is largely
attributable to our customer-focused philosophy and our aggressive marketing
strategy.


    We have developed a capital-efficient network platform to deliver voice
services to our customers. In most of our markets, we lease substantially all of
the network elements from the incumbent telephone company and use our advanced
back-office systems to combine these elements into integrated Birch-branded
voice services. This network delivery method, which we call the unbundled
network element platform, or UNE-P, has allowed us to offer voice services to
customers located virtually anywhere in our markets and achieve high gross
margins and superior returns on incremental capital invested. UNE-P allows us to
minimize current capital expenditures and maintain design flexibility for the
next generation of telecommunications technology.


    We currently operate 29 data switches and a high-speed network
interconnecting these switches to carry data traffic across our region. We
intend to be one of the first carriers in our markets to deliver broadband
facilities directly to our small and mid-sized business customers. By
implementing digital subscriber line technology to transmit both data and voice
traffic over a single line, we expect to significantly reduce the per-line costs
of providing and leasing telephone lines. These savings should


                                       1
<PAGE>
allow us to offer a more attractive package of data and voice services to our
customers and improve our gross margins. We are beta-testing technologies
provided by third-party vendors that we expect will allow us to provide voice
services over digital subscriber lines.


    We offer our customers simplified packages of voice and high-speed data
services designed for small and mid-sized businesses, which are conveniently
billed on a single invoice. In each of our markets, we deploy a locally based
sales force that consults with our customers to assist them in selecting an
appropriate service package that will meet their needs. Our 196-person direct
sales force is supported by aggressive multi-media advertising campaigns
designed to enhance awareness of the Birch name. We believe that our
customer-oriented approach to small and mid-sized businesses provides us with an
advantage over incumbent telephone companies, who are not focused on these
customers.


                                  OUR STRATEGY

    We believe that our business is poised for rapid expansion and that our
experienced management team is well prepared to execute our focused business
strategy. The key elements of our strategy include:

    - FOCUSING ON SMALL AND MID-SIZED BUSINESS CUSTOMERS;

    - PROVIDING COMPLETE SERVICE PACKAGES THAT ARE TAILORED TO OUR CUSTOMERS;

    - CREATING A STRONG BRAND PRESENCE;

    - DEPLOYING A DIRECT SALES FORCE IN EACH OF OUR MARKETS;

    - INVESTING IN INDUSTRY-LEADING, SCALABLE BACK OFFICE SYSTEMS;

    - MAINTAINING MAXIMUM NETWORK FLEXIBILITY;

    - EXPANDING OUR GEOGRAPHIC REACH; AND

    - GROWING THROUGH ACQUISITIONS.

                                 RECENT EVENTS


    In August 1999, an affiliate of KKR purchased $60.0 million of our preferred
stock and, in April 2000, invested an additional $50.0 million in our company.
KKR's investment will be converted into common stock at the closing of the
offering. KKR is our largest stockholder and KKR's investment represents a 51.2%
equity interest as of June 23, 2000. Upon closing of the offering, KKR will
beneficially own approximately     % of our outstanding common stock.


    In December 1999, we obtained a $75.0 million senior credit facility, which
was increased to $125.0 million in February 2000. This credit facility provides
for a $25.0 million reducing revolver and $100.0 million in multi-draw term
loans. The revolver is available for general corporate purposes of our
subsidiaries, and the term loans are to be used to finance telecommunications
equipment, inventory, network assets and back office systems.

Use of proceeds..............................  We estimate that our net proceeds from the
                                               offering will be approximately $184.0
                                               million, based on an assumed initial public
                                               offering price of $     per share, or $211.9
                                               million if the underwriters exercise their
                                               over-allotment option. We plan to use the net
                                               proceeds from the offering to fund capital
                                               expenditures and operating losses and for
                                               general corporate purposes, including
                                               possible future investments, acquisitions or
                                               strategic alliances.

</TABLE>


    The calculation of the number of shares outstanding after the offering is
based on:


    - the number of shares outstanding on June 23, 2000, which reflects the
      1.795-for-1 split of our common stock that occurred on April 6, 2000; and



    - conversion of our preferred stock into 74,147,135 shares of common stock,
      which will occur automatically upon completion of the offering.



    This total does not reflect:


    - shares that may be issued upon the exercise of outstanding options and
      warrants; or

    - shares that are reserved for future issuance pursuant to our employee and
      director stock plans.

preferred stock into common stock, which will occur upon completion of the
offering, and give effect to the additional $50.0 million investment in our
company by an affiliate of KKR, as if these events had occurred on March 31,
2000. The pro forma as adjusted balance sheet data presented below give effect
to the pro forma items listed above and reflect the sale of         shares of
common stock in the offering at an assumed public offering price of $   per
share as if these events had occurred on March 31, 2000. The pro forma net loss
per share calculations give effect to all of the pro forma items listed above,

management and some investors as an indicator of a company's historical ability
to service debt. Management believes that an increase in EBITDA is an indicator
of improved ability to service existing debt, to sustain potential future
increases in debt and to satisfy capital requirements. We have presented EBITDA
to enhance your understanding of our operating results. You should not construe
it as an alternative to operating income, as an indicator of our operating
performance nor as an alternative to cash flows from operating activities as a
measure of liquidity determined in accordance with generally accepted accounting
principles, or GAAP. We may calculate EBITDA differently from other companies.
For further information, see our consolidated financial statements and the
related notes elsewhere in this prospectus.

    The predecessor company is Valu-Line Companies, Inc., which merged with us
in February 1998. Prior to February 1998, Birch had no revenues and was a
development stage company.

    We acquired Boulevard Phone Company, Telesource Communications, Inc. and
TFSnet, Inc. in 1998 and American Local Telecommunications, LLC and Capital
Communications Corporation in 1999. The statement of operations data, other
financial data and operating data in the table include the operations of these
companies beginning on the dates they were acquired. These acquisitions affect
the comparability of the financial data for the periods presented.

                                  RISK FACTORS

    YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISKS AS WELL AS THE OTHER
INFORMATION CONTAINED IN THIS PROSPECTUS BEFORE INVESTING IN SHARES OF OUR
COMMON STOCK. IF ANY OF THE FOLLOWING RISKS ACTUALLY OCCURS, OUR BUSINESS COULD
BE HARMED. IN THAT CASE, THE TRADING PRICE OF THE COMMON STOCK COULD DECLINE AND
YOU MIGHT LOSE ALL OR PART OF YOUR INVESTMENT. YOU SHOULD ALSO REFER TO THE
OTHER INFORMATION SET FORTH IN THIS PROSPECTUS, INCLUDING OUR FINANCIAL
STATEMENTS AND THE RELATED NOTES.

                         RISKS RELATED TO OUR BUSINESS

WE HAVE A LIMITED HISTORY UPON WHICH YOU CAN BASE YOUR INVESTMENT DECISION.

    We commenced operations in February 1998, and since that time we have grown
rapidly. As a result of our limited operating history, you have limited
operating and financial data about us upon which to base an evaluation of our
performance and an investment in our common stock. Our ability to provide an
integrated package of bundled telecommunications services on a widespread basis
and to generate operating profits and positive operating cash flow will depend
upon our ability, among other things, to:

    - develop our operational support and other back office systems;

    - obtain state authorizations to operate as a competitive local exchange
      carrier and any other required governmental authorizations;

    - increase awareness of our brand and attract and retain an adequate
      customer base;

    - raise additional capital;

    - attract and retain qualified personnel;

    - enter into and implement interconnection agreements with established
      telephone companies on satisfactory terms; and

    - enter into new markets and successfully compete for business in different
      environments.

    We cannot assure you that we will be able to achieve any of these
objectives, generate sufficient revenues to achieve or sustain profitability,
meet our working capital and debt service requirements or compete successfully
in the telecommunications industry.

WE HAVE A HISTORY OF OPERATING LOSSES, AND WE MAY NOT BE PROFITABLE IN THE
FUTURE.


    We have incurred significant losses since we began operations as a
competitive telecommunications provider and expect to continue to incur losses
in the future as we build our network. For the quarter ended March 31, 2000 we
had operating losses of $19.2 million, a net loss of $23.3 million and an
accumulated deficit of $103.1 million. For the year ended December 31, 1999, we
had operating losses of $49.7 million, a net loss of $61.8 million and an
accumulated deficit of $79.8 million. We expect to experience losses during our
network and service deployment, which will continue for the foreseeable future.
Prolonged effects of generating losses without additional funding may restrict
our ability to pursue our business strategy. Unless our business plan is
successful, your investment in our common stock may result in a complete loss of
your invested capital.


    If we cannot achieve profitability from operating activities, we may not be
able to meet:

    - our capital expenditure requirements;

    - our debt service obligations; or

    - our working capital needs.

                                       6
<PAGE>
OUR HIGHLY LEVERAGED CAPITAL STRUCTURE LIMITS OUR ABILITY TO OBTAIN ADDITIONAL
FINANCING AND COULD ADVERSELY AFFECT OUR BUSINESS IN SEVERAL OTHER WAYS.


    The level of our outstanding debt greatly exceeds the level of our revenue
and stockholders' equity. As of May 31, 2000, we had $166.1 million of long-term
indebtedness outstanding, including $50.0 million outstanding under our senior
credit facility and $114.7 million of senior notes outstanding. At May 31, 2000,
we had $75.0 million available for borrowing under our senior credit facility.
We may, and are also permitted under the terms of our debt instruments to, incur
substantial indebtedness in the future. We are currently renegotiating the terms
of the senior credit facility, including increasing the size of the facility.


    Our large amount of indebtedness could significantly impact our business for
the following reasons:

    - it limits our ability to obtain additional financing to complete our
      roll-out plan, to develop new services or to otherwise respond to
      unanticipated competitive pressures;

    - it means that we will need to dedicate a substantial portion of our
      operating cash flow to fund interest expense on our senior credit facility
      and our senior notes, thereby reducing funds available for working
      capital, capital expenditures or other purposes;

    - it makes us vulnerable to interest rate fluctuations because our senior
      credit facility loans bear interest at variable rates;

    - it limits our ability to compete with companies who are not as highly
      leveraged, especially those who may be able to price their service
      offerings at levels below those we can or are willing to match; and

    - it limits our ability to expand into new markets and to react to changing
      market conditions, changes in our industry and economic downturns.

OUR EXISTING DEBT INCLUDES RESTRICTIVE AND FINANCIAL COVENANTS THAT LIMIT OUR
OPERATING FLEXIBILITY.

    Our senior credit facility and the indenture relating to our senior notes
contain covenants that, among other things, restrict our ability to take
specific actions, even if we believe them to be in our best interest. These
include restrictions on our ability to:

    - incur additional debt;

    - pay dividends or distributions on, or redeem or repurchase, capital stock;

    - create liens or negative pledges with respect to our assets;

    - make investments, loans or advances;

    - issue, sell or allow distributions on capital stock of specified
      subsidiaries;

    - enter into sale and leaseback transactions;

    - prepay or defease specified indebtedness;

    - enter into transactions with affiliates;

    - enter into specified hedging arrangements;

    - merge, consolidate or sell our assets; or

    - engage in any business other than telecommunications.

    The senior notes also require us to offer to purchase these notes from the
holders at 101% if we undergo a change of control. In addition, the senior
credit facility imposes financial covenants that require us to comply with
specified financial ratios and tests, including minimum revenues, minimum

                                       7
<PAGE>
EBITDA/maximum EBITDA losses, minimum access lines, senior secured debt to total
capitalization, maximum capital expenditures, maximum leverage ratios, minimum
interest coverage ratios and pro forma debt service coverage ratios. We cannot
assure you that we will be able to meet these requirements or satisfy these
covenants in the future. If we fail to do so, our debts could become immediately
payable at a time when we are unable to pay them. This could adversely affect
our ability to carry out our business plan and would have a negative effect on
our financial condition.

WE EXPECT TO GROW AND CANNOT GUARANTEE THAT WE WILL BE ABLE TO EFFECTIVELY
MANAGE OUR FUTURE GROWTH.

    If we successfully implement our business plan, our operations will expand
rapidly, and we will be providing packaged telecommunications services on a
widespread basis. This could place a significant strain on our management,
operational, financial and other resources and increase demands on our systems
and controls. Failure to manage our future growth effectively could adversely
affect the expansion of our customer base and service offerings. We cannot
assure you that we will successfully implement and maintain efficient
operational and financial systems, procedures and controls or successfully
obtain, integrate and manage the employees and management, operational,
financial and other resources necessary to manage a developing and expanding
business in our evolving, highly regulated and increasingly competitive
industry.

TO EXPAND AND DEVELOP OUR BUSINESS WE WILL NEED A SIGNIFICANT AMOUNT OF CASH,
WHICH WE MAY BE UNABLE TO OBTAIN.

    The expansion and development of our business and the deployment of our
networks, services and systems will require significant capital expenditures,
working capital and debt service and generate negative operating cash flows.

    The actual amount and timing of our future capital requirements may differ
materially from our estimates as a result of, among other things, the demand for
our services and regulatory, technological and competitive developments,
including additional market developments and new opportunities, in our industry.
Our revenue and costs may also be dependent upon factors that are not within our
control, including regulatory and legislative developments, the response of our
competitors to their loss of customers to us and to changes in technology, the
nature and penetration of services that we may offer and the number of
subscribers and the services for which they subscribe. Due to the uncertainty of
these factors, actual revenues and costs may vary from expected amounts,
possibly to a material degree, and these variations are likely to affect our
future capital requirements.


    We also expect that we will require additional financing or may require
financing sooner than anticipated to complete our roll-out plan or if our
development plans change or prove to be inaccurate. We may also require
additional financing in order to develop new services or to otherwise respond to
changing business conditions or unanticipated competitive pressures. Sources of
additional financing may include commercial bank borrowings, vendor financing,
or the private or public sale of equity or debt securities. If we decide to
raise additional funds through the incurrence of debt, our interest obligations
will increase, and we may become subject to additional or more restrictive
financial covenants, which could impair our ability to develop our business. If
we decide to raise additional funds through the issuance of equity, the
ownership interests represented by the common stock will be diluted. Although we
are currently renegotiating the terms of our senior credit facility, including
increasing the size of the facility, we cannot assure you that we will be
successful in raising sufficient additional capital on favorable terms or at
all. Failure to raise sufficient funds may require us to modify, delay or
abandon some of our future expansion or expenditure plans.


                                       8
<PAGE>
RESISTANCE BY POTENTIAL CUSTOMERS TO ACCEPT US AS A NEW PROVIDER OF
TELECOMMUNICATIONS SERVICES MAY REDUCE OUR ABILITY TO INCREASE OUR REVENUE.

    The success of our service offerings will depend upon, among other things,
the willingness of additional customers to accept us as a new provider of
integrated communications services. We cannot assure you that we will be
successful in overcoming the resistance of potential customers to change their
service provider, particularly those that purchase services from the traditional
telephone companies, or that customers will buy our services. Any lack of
customer acceptance would reduce our ability to increase our revenue.

IF WE ARE UNABLE TO DEVELOP OR INTEGRATE OUR SYSTEMS OR PROPERLY MAINTAIN AND
UPGRADE THEM, WE MAY NOT BE ABLE TO BILL OUR CUSTOMERS EFFECTIVELY OR PROVIDE
ADEQUATE CUSTOMER SERVICE.

    Sophisticated back office information and processing systems are vital to
our growth and our ability to monitor costs, bill customers, provision customer
orders, achieve operating efficiencies and maintain our operating margins. Our
plans for the development and implementation of these systems rely, for the most
part, on choosing products and services offered by third party vendors and
integrating these products and services in-house to produce efficient
operational solutions. We cannot assure you that we will successfully implement
these systems on a timely basis or that we will implement them at all. We also
cannot assure you that, once implemented, these systems will perform as we
expect. Risks to our business associated with our systems include:

    - failure by these vendors to deliver their products and services in a
      timely and effective manner and at acceptable costs;

    - failure by us to identify all of our information and processing needs
      adequately;

    - failure of our related processing or information systems; or

    - failure by us to effectively integrate new products or services.

    Furthermore, as our suppliers revise and upgrade their hardware, software
and equipment technology, we could encounter difficulties in integrating this
new technology into our business or the new systems may not be appropriate for
our business. In addition, our right to use these systems depends upon license
agreements with third party vendors. Vendors may cancel or elect not to renew
some of these agreements, which may adversely affect us.

WE MAY NEED TO RELY ON THE ESTABLISHED LOCAL TELEPHONE COMPANIES TO IMPLEMENT
OUR SERVICES SUCCESSFULLY. THEIR FAILURE TO COOPERATE WITH US COULD ADVERSELY
AFFECT THE SERVICES WE OFFER.

    We are a recent entrant into the local telecommunications services industry.
The local exchange services market in most states was only recently opened to
competition. There are numerous operating complexities associated with providing
these services. We will be required to develop new products, services and
systems and will need to develop new marketing initiatives to sell these
services. We cannot assure you that we will be able to develop these products
and services.

    We plan to deploy high capacity voice and data switches in most of the
markets we serve. We initially intend to rely on the networks of established
telephone companies or those of new market entrants for some aspects of
transmission. Federal law requires most of the traditional local telephone
companies to lease or "unbundle" elements of their networks and permit us to
purchase the elements we need, thereby decreasing our operating expenses. We
cannot assure you that this unbundling will continue to occur in a timely manner
or that the prices for these elements will be favorable to us. Our current
strategy depends in large part on our ability to provide service to our
customers by leasing all of the network elements necessary to provide local
telephone service from the incumbent telephone company rather than through the
use of our own equipment and facilities. UNE-P allows us to

                                       9
<PAGE>
minimize capital expenditures and permits us to enter new markets quickly, while
allowing us to maintain significant gross margins. If the incumbent local
telephone companies do not cooperate in making UNE-P available, our ability to
provide service to customers could be materially adversely affected.


    In addition, our ability to implement successfully our services will require
the negotiation of interconnection and collocation agreements with established
telephone companies and other new market entrants, which can take considerable
time, effort and expense and which is subject to federal, state and local
regulation. Interconnection agreements are agreements between local
telecommunications services providers that set forth the terms and conditions
governing how those providers will interconnect their networks and/or purchase
or lease network facilities and services.


    Our interconnection agreements with Southwestern Bell provide that our
connection and maintenance orders will receive the same attention as
Southwestern Bell's end-user customers and that Southwestern Bell will provide
capacity at key telecommunications intersections to keep call blockage within
industry standards. Accordingly, we depend and will continue to depend on
Southwestern Bell and, as we expand our network, we will depend on other
traditional telephone companies to assure uninterrupted service and competitive
services. Blocked calls result in customer dissatisfaction and risk the loss of
business. Interconnection agreements, such as our agreements with Southwestern
Bell, typically have short terms, requiring us to renegotiate frequently. Some
of our agreements with Southwestern Bell have one year or less remaining before
we will have to renegotiate them. We cannot assure you that we will be able to
renegotiate these interconnection agreements in our existing markets, or
negotiate new interconnection agreements in new markets, on favorable terms. In
addition, the prices set forth in our interconnection agreements may be subject
to significant rate increases at the discretion of the regulatory authority in
each state in which we operate. Our profitability partially depends on these
state-regulated rate structures. We cannot assure you that the rates charged to
us under the interconnection agreements will allow us to offer low enough usage
rates to attract a sufficient number of customers and to operate our business
profitably or at favorable gross margins.

    Many new carriers have experienced difficulties in working with the
established telephone companies with respect to ordering, interconnecting,
leasing premises and implementing the systems used by these new carriers to
order and receive unbundled network elements and wholesale services. We cannot
assure you that established telephone companies will be accommodating to us. If
we are unable to obtain the cooperation of an established telephone company in a
region, our ability to offer local services in this region on a timely and
cost-effective basis would be adversely affected. In addition, both proposed and
recently completed mergers involving regional Bell operating companies and other
competitors could facilitate a combined entity's ability to provide many of the
services we offer, thereby making it more difficult to compete against them.

DIGITAL SUBSCRIBER LINE TECHNOLOGY MAY NOT OPERATE AS EXPECTED ON INCUMBENT
LOCAL CARRIER NETWORKS AND MAY INTERFERE WITH OR BE AFFECTED BY OTHER TRANSPORT
TECHNOLOGIES.

    Our ability to provide digital subscriber line services to potential
customers depends on the quality, physical condition, availability and
maintenance of telephone lines within the control of the incumbent carriers. If
the telephone lines are not adequate, we may not be able to provide digital
subscriber line services to many of our target customers, and this will diminish
our expected revenue. We believe the current condition of telephone lines in
many cases may be inadequate to permit us to fully implement these services. We
also believe that the incumbent carriers may not maintain or improve the
telephone lines in a condition that will allow us to implement our digital
subscriber line services effectively. Further, the incumbent carriers may claim
their lines are not of sufficient quality to allow us to fully implement or
operate our digital subscriber line services. In addition, some customers use
technologies other than copper lines to provide telephone services, and as a
result, digital subscriber line services might not be available to these
customers.

                                       10
<PAGE>
    All transport technologies using copper telephone lines have the potential
to interfere with, or to be interfered with by, other traffic on adjacent copper
telephone lines. This interference could degrade the performance of our services
or make us unable to provide service on selected lines. In addition, incumbent
carriers may claim that the potential for interference by digital subscriber
line technology permits them to restrict or delay our deployment of this
technology. The telecommunications industry and regulatory agencies are still
developing procedures to resolve interference issues between telecommunications
providers, and these procedures may not be effective. We may be unable to
successfully negotiate interference resolution procedures with incumbent
carriers. Interference, or claims of interference, if widespread, would
adversely affect our speed of deployment, reputation, brand image, service
quality and customer retention and satisfaction.

IF WE ARE UNABLE TO ATTRACT AND RETAIN KEY MANAGEMENT AND PERSONNEL, WE MAY NOT
BE ABLE TO IMPLEMENT OUR BUSINESS PLAN.

    We believe that our future success will be due, in part, to our experienced
management team, including Messrs. Scott, Goldman, Hollingsworth, Lawhon,
Moline, Shackelford and Vranicar, each of whom is party to an employment
agreement. Losing the services of one or more members of our management team
could adversely affect our business and our expansion efforts and possibly
prevent us from:

    - further deploying and improving our operational, financial and information
      systems and controls;

    - hiring and retaining qualified sales, marketing, administrative, operating
      and technical personnel; and

    - training and managing new personnel.

    In addition, competition for qualified employees has intensified in recent
years and may become even more intense in the future. Our ability to implement
our business plan depends on our ability to hire and retain a large number of
new employees each year. Inability to hire sufficient qualified personnel could
impair our ability to increase revenue, and customers could experience delays in
installation of service or experience lower levels of customer care.

WE MAY NOT HAVE THE ABILITY TO DEVELOP STRATEGIC ALLIANCES OR TO MAKE OR
SUCCESSFULLY INTEGRATE ACQUISITIONS NEEDED TO COMPLEMENT OUR EXISTING BUSINESS.

    As part of our growth strategy, we seek to develop strategic alliances and
to make investments or acquire assets or other businesses. We regularly engage
in discussions relating to potential acquisitions. We are unable to predict
whether or when any prospective acquisitions or strategic alliances will occur
or the likelihood of a material transaction being completed on favorable terms
and conditions. Our ability to finance acquisitions and strategic alliances may
be constrained by our degree of leverage at the time of the acquisition. In
addition, our senior credit facility and senior notes may significantly limit
our ability to make acquisitions or enter into strategic alliances and to incur
indebtedness in connection with acquisitions and strategic alliances.

    In addition, if we were to proceed with one or more significant strategic
alliances, acquisitions or investments in which the consideration consists of
cash, we could use a substantial portion of our available cash, including
proceeds of the offering, to consummate the strategic alliances, acquisitions or
investments. The financial impact of acquisitions, investments and strategic
alliances could cause substantial fluctuations in our quarterly and yearly
operating results. Furthermore, if we use our common stock as consideration for
acquisitions, our stockholders would experience dilution of their existing
shares.

                                       11
<PAGE>
    The integration of any future acquisitions or strategic alliances would be
accompanied by the risks commonly encountered in these transactions. These risks
include, among others:

    - the difficulty of assimilating the acquired operations and personnel;

    - the potential disruption of our ongoing business and diversion of
      resources and management time;

    - the inability of management to maximize our financial and strategic
      position by the successful incorporation of licensed or acquired
      technology and rights into our service offerings;

    - the possible inability of management to maintain uniform standards,
      controls, procedures and policies;

    - the risks of entering markets in which we have little or no direct prior
      experience; and

    - the potential impairment of relationships with employees or customers as a
      result of changes in management or otherwise arising out of these
      transactions.

We cannot assure you that we will be able to integrate acquired businesses or
assets successfully.

A SYSTEM FAILURE COULD CAUSE DELAYS OR INTERRUPTIONS OF SERVICE, WHICH COULD
CAUSE US TO LOSE CUSTOMERS.

    Our success will require that our networks provide competitive reliability,
capacity and security. Some of the risks to our networks and infrastructure
include:

    - physical damage to access lines;

    - power surges or outages;

    - capacity limitations;

    - software defects;

    - lack of redundancy; and

    - disruptions beyond our control.

    These disruptions may cause interruptions in service or reduced capacity for
customers, any of which could cause us to lose customers.

ALL YEAR 2000 PROBLEMS MAY NOT HAVE BEEN ADDRESSED BY OUR SUPPLIERS, AND ANY
SERVICE INTERRUPTION WE EXPERIENCE AS A RESULT OF THESE PROBLEMS MAY CAUSE US TO
LOSE CUSTOMERS.

    The Year 2000 issue generally describes the various problems that may result
from the improper processing of dates and date-sensitive transactions by
computers and other equipment as a result of computer hardware and software
using two digits, rather than four digits, to identify the year in a date. Any
computer programs or systems of our suppliers that have date-sensitive software
may recognize a date using "00" as the year 1900 rather than the year 2000.
While we have experienced no Year 2000 issues to date, and we are not aware of
any material issues for our suppliers, we are continuing to evaluate and
determine whether our significant suppliers are in compliance or have
appropriate plans to remedy Year 2000 issues when their systems interact with
our systems. We do not expect that this will have a material impact on our
operations. However, we cannot assure you that the systems of other companies on
which we rely are Year 2000 compliant, that another company's failure to
successfully convert, or that another company's conversion to a system
incompatible with our systems, would not have an impact on our operations. The
failure of our principal suppliers to be Year 2000 compliant could result in
delays in service deliveries from those suppliers and materially impact our
ability to do business.

                         RISKS RELATED TO OUR INDUSTRY

WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY AGAINST OTHER COMPANIES.

    The telecommunications industry is highly competitive and is affected by the
introduction of new services by, and the market activities of, major industry
participants. Several of our competitors are substantially larger and have
greater financial, technical and marketing resources than we do. We have not
achieved, and do not expect to achieve, a significant market share for any of
the broadband telecommunications services we offer in our target markets. In
particular, larger competitors have advantages over us that could cause us to
lose customers and impede our ability to attract new customers, including:

    - long-standing relationships and brand recognition with customers;

    - financial, technical, marketing, personnel and other resources
      substantially greater than ours;

    - more funds to deploy telecommunications services;

    - potential to lower prices of competitive telecommunications services; and

    - fully deployed networks.

    We face competition from other current and potential market entrants,
including:

    - domestic and international long distance providers seeking to enter,
      re-enter or expand entry into the local telecommunications marketplace;
      and

    - other domestic and international telecommunications providers, resellers,
      cable television companies, electric utilities and Internet companies.

    A continuing trend toward combinations and strategic alliances in the
telecommunications industry could give rise to significant new competitors. This
could cause us to lose customers and impede our ability to attract new
customers.

FEDERAL COMMUNICATIONS COMMISSION AND STATE REGULATIONS MAY LIMIT THE SERVICES
WE CAN OFFER OR IMPACT OUR ABILITY TO CONDUCT OUR BUSINESS.

    Our networks and the provision of telecommunications services are
extensively regulated at the federal, state and local levels. Existing and
future governmental regulations may greatly influence how we operate our
business, our business strategy and ultimately, our viability. The costs of
complying with federal, state and local regulations and the delays in receiving
required regulatory approvals or the enactment of new adverse regulation or
regulatory requirements may be greater than we anticipate and divert our
resources from implementing our business plan. We cannot predict the future
regulatory framework for our business.

    Our provision of telecommunications services may be subject to the
requirement that we obtain proper authorizations from the FCC or state
commissions. We cannot assure you that the FCC or state commissions will grant
the required authority or refrain from taking action against us if we are found
to have provided services without obtaining the necessary authorizations. If we
do not fully comply with the rules of the FCC or state regulatory agencies,
third parties or regulators could challenge our authority to do business. These
challenges could cause us to incur substantial legal and administrative
expenses.

    Federal law governing the telecommunications industry remains in a state of
flux. The Telecommunications Act remains subject to judicial review and
additional FCC rulemaking, and thus it is difficult to predict what effect the
legislation or these FCC rules will have on us and our operations. There are
currently many regulatory actions underway and being contemplated by federal and
state authorities regarding interconnection pricing, universal service support,
access charge reform, and other

                                       13
<PAGE>
issues that could result in significant changes to the business conditions in
the telecommunications industry.

    Our current business strategy depends in large part on our ability to
provide service to our customers through UNE-P. Our ability to provide service
to customers through UNE-P depends in turn on FCC and state commission rulings
requiring incumbent local telephone companies to lease us the necessary network
elements. If those rules are changed by the FCC or state commissions, or are
struck down by the courts, our ability to provide service to our customers
through UNE-P could be materially adversely affected. For example, the FCC could
remove one or more of the necessary elements from the list of elements that the
incumbent telephone companies are required to provide to us. The FCC could also
expand the scope of an existing exception in its rules that permits incumbent
telephone companies to opt not to make UNE-P available in the highest density
geographic areas within the largest 50 metropolitan statistical areas if they
meet certain conditions. If the FCC acts to expand the scope of the geographic
exception to include our target markets, our business could be materially
adversely affected. Some states in our current operating region, including Texas
and Missouri, have gone beyond the FCC's minimum requirements and independently
ordered Southwestern Bell to make UNE-P available throughout those states under
terms more favorable to new telecommunications service providers than those
required by the FCC. We cannot assure you that those favorable state rulings
will remain in place. If UNE-P does not continue to be available on the
favorable terms ordered by the states, our business could be materially
adversely affected.

    The United States Court of Appeals for the Eighth Circuit is currently
considering challenges to the pricing methodology established by the FCC for
setting the rates paid by telecommunications service providers to incumbent
telephone companies for access to network elements. If the court strikes down
some or all of the FCCs's pricing methodology and that methodology is ultimately
replaced with a methodology that imposes higher rates for network elements, we
could be materially adversely affected.


    Federal universal service support mechanisms could increase the costs of
providing service to our customers. We derive revenue from the provision of
interstate and international telecommunications services to end users that may
be subject to the requirement that we contribute to the FCC's Universal Service
Fund based on a percentage of this revenue. The assessment for the second
quarter of 2000 is 5.7101%, and the proposed assessment for the third quarter of
2000 is 5.5360% of interstate and international end user telecommunications
revenue. The contribution factor varies quarterly at a rate set by the FCC. To
the extent the contribution factor increases, our costs of providing service
will increase.


    Our Internet operations are not currently regulated directly by the FCC or
any other governmental agency, other than regulations applicable to businesses
generally. However, the FCC has recently indicated that the regulatory status of
some services offered over the Internet may have to be re-examined. New laws or
regulations relating to Internet services, or existing laws found to apply to
them, may adversely affect our Internet operations.

WE MAY BE UNABLE TO ADAPT TO TECHNOLOGICAL CHANGE.

    The telecommunications industry is subject to rapid and significant changes
in technology, including continuing developments in digital subscriber line
technology. This technology does not presently have widely accepted standards,
and alternative technologies for providing high speed data transport and
networking may develop. The absence of widely accepted standards may delay or
increase the cost of our market entry due to changes in equipment specifications
and customer needs and expectations. We may also rely on a third party for
access to new technologies. In addition, if we acquire new technologies, we may
not be able to implement them as effectively as other companies with more
experience with those technologies and in their markets.

                                       14
<PAGE>
WE MAY FAIL TO ACHIEVE ACCEPTABLE PROFITS ON OUR LONG DISTANCE BUSINESS DUE TO
DECLINING PRICES, LOW CUSTOMER RETENTION RATES AND OUR CONTRACTUAL OBLIGATIONS.

    Prices in the long distance business have declined substantially in recent
years and are expected to continue to decline. In addition, the long distance
industry has a low customer retention rate, as customers frequently change long
distance providers in response to the offering of lower rates or promotional
incentives by competitors. We will rely on other carriers to provide us with a
major portion of our long distance transmission network. Agreements with these
carriers typically provide for the resale of long distance services on a
per-minute basis and may contain minimum volume commitments. The negotiation of
these agreements involves estimates of future supply and demand for transmission
capacity, as well as estimates of the calling patterns and traffic levels of our
future customers. In the event that we fail to meet these minimum volume
commitments, we may have to pay underutilization charges, and, in the event we
underestimate our need for transmission capacity, we may have to obtain capacity
through more expensive means.

AS A NEW DATA TRANSMISSION ENTRANT IN A MARKET, WE MAY INITIALLY GENERATE LOW OR
NEGATIVE GROSS MARGINS.

    As a new entrant in the data transmission business, we expect to generate
low or negative gross margins and substantial start-up expenses as we begin to
offer data transmission services. The success of our data transmission business
will depend upon, among other things, the effectiveness of our sales personnel
in the promotion and sale of our data transmission services, the acceptance of
these services by potential customers, and our ability to hire and train
qualified personnel and further enhance our services in response to future
technological changes. We cannot assure you that we will be successful in these
endeavors.

                         RISKS RELATED TO THIS OFFERING

YOU MIGHT NOT BE ABLE TO SELL YOUR STOCK IF NO MARKET DEVELOPS FOR OUR STOCK.


    Prior to the offering, you could not buy or sell our common stock publicly.
Our application to have our common stock quoted on The Nasdaq National Market
has been approved. However, an active public market for our common stock may not
develop or be sustained after the offering. If a market does not develop or is
not sustained, it may be difficult for you to sell your shares of common stock
at a price that is attractive to you or at all. The initial public offering
price of the common stock will be determined through negotiations between the
representatives of the underwriters and us and may not be representative of the
price that will prevail in the open market.


PROVISIONS IN OUR CHARTER DOCUMENTS MIGHT DETER ACQUISITION BIDS FOR US.

    We intend to amend and restate our certificate of incorporation prior to the
closing of the offering. This amended and restated certificate of incorporation
will provide for, among other things:

    - a classified board of directors;

    - the inability of our stockholders to call special meetings of
      stockholders, to act by written consent unless the consent is unanimous,
      to remove any director or the entire board of directors without cause, or
      to fill any vacancy on the board of directors; and

    - advance notice requirements for stockholder proposals.

    Our board of directors will also be permitted to authorize the issuance of
preferred stock without any vote or further action by the stockholders. These
provisions and other provisions under Delaware law could make it more difficult
for a third party to acquire us, even if doing so would benefit our
stockholders.

                                       15
<PAGE>
KKR WILL BENEFICIALLY OWN A SIGNIFICANT INTEREST IN OUR VOTING SECURITIES AFTER
THE OFFERING.


    KKR will beneficially own     % of our outstanding shares of common stock
following the completion of the offering and     % if the underwriters'
overallotment option is exercised in full. As a result, KKR will exercise
significant control over all matters requiring stockholder approval. Under the
terms of a purchasers' rights agreement, KKR is currently entitled to designate
a total of five out of the eleven members of the board of directors and two
members of the compensation committee of the board. The concentrated holdings of
KKR and the presence of its designees on the board of directors may result in a
delay or the deterrence of possible changes in our control, which may reduce the
market price of our common stock. In addition, KKR and its affiliates have the
right to veto many actions that we may take, including any change in our capital
stock, any payments of dividends, any change in the composition of our board,
any affiliate transactions, any consolidation, reorganization, merger or similar
transaction, any change in our governing documents or any voting or similar
agreement concerning our capital stock, as well as specified operating decision,
including, but not limited to, incremental indebtedness, investments and our
business plan.


OUR MANAGEMENT WILL HAVE BROAD DISCRETION IN APPLYING THE NET PROCEEDS OF THIS
OFFERING.


    At an initial offering price of $    and after deducting the underwriting
discount and other expenses of the offering, we will receive net proceeds of
approximately $184.0 million. We have not yet determined the specific dollar
amount of net proceeds to be allocated to any of the possible uses indicated in
"Use of Proceeds." Accordingly, our management will have broad discretion in
applying the net proceeds of the offering. Management's allocation of the net
proceeds will affect how our business evolves. We cannot assure you that
management will choose to spend these proceeds in areas that benefit our
business. In addition, we cannot assure you that management will choose to
allocate proceeds to further our current business strategy.


FUTURE SALES OF SHARES BY EXISTING STOCKHOLDERS COULD AFFECT OUR STOCK PRICE.


    If our existing stockholders sell substantial amounts of our common stock in
the public market following the offering, the market price of our common stock
could decline. Based on shares outstanding as of June 23, 2000, upon completion
of the offering we will have outstanding         shares of common stock,
assuming no exercise of the underwriters' over-allotment option. Of these
shares, the         shares of common stock sold in the offering will be freely
tradeable, without restriction, in the public market, and        additional
shares (including shares issuable upon the exercise of outstanding warrants)
will be eligible for sale in the public market immediately upon completion of
the offering. After the lockup agreements pertaining to the offering expire
180 days from the date of this prospectus, subject to some exceptions, an
additional 79,912,477 shares will be eligible for sale in the public market. In
addition, the 14,021,201 shares subject to outstanding or early exercised
options and 12,565,000 shares reserved for future issuance under our stock
option and purchase plans will be available for sale after 180 days from the
date of this prospectus. Following the offering, we intend to file a
registration statement on Form S-8 under the Securities Act covering
approximately 27,700,000 shares of common stock issued or issuable upon the
exercise of stock options, subject to outstanding options or reserved for
issuance under our employee and director stock plans.


YOU WILL INCUR IMMEDIATE AND SUBSTANTIAL DILUTION.


    The initial public offering price is substantially higher than the pro forma
net book value per share of the outstanding common stock. As a result, investors
purchasing common stock in the offering will incur immediate substantial
dilution in the amount of $    per share. In addition, we have issued options
and warrants to acquire common stock at prices significantly below the initial
public offering price. To the extent these outstanding options and warrants are
exercised, there will be further dilution to investors in this offering.


                                       16
<PAGE>
OUR STOCK DOES NOT HAVE A TRADING HISTORY AND MAY BE EXTREMELY VOLATILE BECAUSE
WE OPERATE IN A RAPIDLY CHANGING INDUSTRY.

    The trading price of our common stock is likely to be volatile. The stock
market has experienced extreme volatility, and this volatility has often been
unrelated to the operating performance of particular companies. We cannot be
sure that an active public market for our common stock will develop or continue
after the offering. Investors may not be able to sell their common stock at or
above our initial public offering price or at all. Prices for the common stock
will be determined in the marketplace and may be influenced by many factors,
including variations in our financial results, changes in earnings estimates by
industry research analysts, investors' perceptions of us and general economic,
industry and market conditions.

OUR OFFICERS AND DIRECTORS EXERT SUBSTANTIAL INFLUENCE OVER US.

    Our executive officers, directors and entities affiliated with them together
beneficially own a substantial percentage of our outstanding common stock. As a
result, these stockholders are able to exercise substantial influence over all
matters requiring approval by our stockholders, including the election of
directors and approval of significant corporate transactions. This concentration
of ownership may also have the effect of delaying or preventing a change in our
control.

THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT MAY NOT BE ACCURATE
INDICATORS OF OUR FUTURE PERFORMANCE.

    This prospectus contains forward-looking statements within the meaning of

                                USE OF PROCEEDS


    We estimate that our net proceeds from the sale of the         shares of
common stock will be approximately $184.0 million, or $211.9 million if the
underwriters exercise their over-allotment option in full, after deducting the
estimated underwriting discount and estimated offering expenses payable by us.


    We expect to use the net proceeds from the offering and borrowings under our
senior credit facility to fund capital expenditures for network facilities and
back office systems, to fund operating losses and for general corporate
purposes, including possible future investments, acquisitions or strategic
alliances. Pending these uses, we plan to invest the net proceeds in investment
grade, interest-bearing securities.

                                DIVIDEND POLICY

    We have never paid or declared any cash dividends on our common stock and do
not anticipate paying cash dividends in the foreseeable future. We currently
intend to retain all future earnings, if any, for use in the operation of our
business and to fund future growth. The terms of our senior credit facility and
our senior notes indenture restrict our ability to declare and pay dividends on
our common stock.

                                 CAPITALIZATION


    The following table sets forth our capitalization as of March 31, 2000:



    - on an actual basis;



    - on a pro forma basis to give effect to (1) the conversion of all
      outstanding shares of our preferred stock into common stock, which will
      occur immediately upon completion of the offering and (2) the exercise by
      an affiliate of KKR of its options to invest an additional $50.0 million
      (net proceeds of $47.5 million) in our company; and



    - on a pro forma as adjusted basis to give effect to the pro forma items
      listed above and reflect the application of the net proceeds from the sale
      of       shares of common stock in the offering at an assumed price of
      $    per share.


    You should read this table in conjunction with our consolidated financial
statements and the related notes, "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Use of Proceeds" included
elsewhere in this prospectus.

    our senior notes through June 2001.



(2) The $125.0 million senior credit facility provides for a $25.0 million
    reducing revolver and $100.0 million in multi-draw term loans. As of
    May 31, 2000, we had borrowed $50.0 million under the senior credit facility
    and had $25.0 million available under the revolver and $50.0 million
    available under the term portion of the senior credit facility.

                                    DILUTION

    Dilution is the amount by which the offering price paid by the purchasers of
the common stock to be sold in the offering will exceed the net tangible book
value per share of common stock after the offering. Net tangible book value per
share is determined at any date by subtracting our total liabilities from the
total book value of our tangible assets and dividing the difference by the
number of shares of common stock deemed to be outstanding at that date.


    Our net tangible book value (deficit) as of March 31, 2000, after giving pro
forma effect to the conversion of all outstanding shares of our preferred stock
into common stock, which will occur automatically upon completion of the
offering, and the additional $50.0 million investment in our company by an
affiliate of KKR, would have been $    million or $    per share. After giving
effect to the receipt of approximately $184.0 million of estimated net proceeds
from the sale of           shares of common stock in the offering at an assumed
offering price of $     per share, our pro forma net tangible book value at
March 31, 2000 would have been approximately $    million or $    per share.
This represents an immediate increase in pro forma net tangible book value of
$    per share to existing stockholders and an immediate dilution of $     per
share to investors purchasing shares of common stock in the offering. The
following table illustrates the substantial and immediate per share dilution to
new investors:

    The table above assumes no exercise of stock options or warrants outstanding
as of March 31, 2000. As of March 31, 2000, there were options outstanding to
purchase a total of 6,266,727 shares of common stock at a weighted average
exercise price of $2.94 per share. We have granted 335,120 additional options
since that date and expect to grant approximately 1,700,000 options exercisable
at the offering price on the closing date of the offering. As of March 31, 2000,
there were warrants outstanding to purchase a total of 2,530,473 shares of
common stock at an exercise price of $0.006 per share. To the extent any of
these options and warrants are exercised, there may be further dilution to new
investors.

               SELECTED CONSOLIDATED FINANCIAL AND OPERATING DATA


    The following table sets forth our selected consolidated financial and
operating data for the periods indicated. Our statement of operations data and
other financial data for the years ended December 31, 1997, 1998 and 1999 and
our balance sheet data as of December 31, 1998 and 1999, as well as the
statement of operations data, other financial data and balance sheet data for
the predecessor company as of and for the year ended December 31, 1997, have
been derived from, and is qualified by reference to, consolidated financial
statements included elsewhere in this prospectus, which Ernst & Young LLP, our
independent auditors, have audited. Our statement of operations data and other
financial data for the three months ended March 31, 1999 and 2000 and our
balance sheet data as of March 31, 1999 and 2000 have been derived from our
unaudited interim condensed consolidated financial statements. The share and per
share data presented below give effect to the 1.795-for-1 split of our common
stock, which occurred on April 6, 2000.


    EBITDA consists of earnings before interest, income taxes, depreciation and
amortization. EBITDA is provided because it is a measure of financial
performance commonly used in the telecommunications industry. EBITDA is used by
management and some investors as an indicator of a company's historical ability
to service debt. Management believes that an increase in EBITDA is an indicator
of improved ability to service existing debt, to sustain potential future
increases in debt and to satisfy capital requirements. We have presented EBITDA
to enhance your understanding of our operating results. You should not construe
it as an alternative to operating income, as an indicator of our operating
performance nor as an alternative to cash flows from operating activities as a
measure of liquidity determined in accordance with GAAP. We may calculate EBITDA
differently from other companies. For further information, see our consolidated
financial statements and the related notes elsewhere in this prospectus.

    The predecessor company is Valu-Line, which merged with us in
February 1998. Prior to February 1998, Birch had no revenues and was a
development stage company.

    We acquired Boulevard, Telesource and TFSnet in 1998 and American Local and
Capital in 1999. The statement of operations data, other financial data and
operating data in the table include the operations of these companies beginning
on the dates they were acquired. These acquisitions affect the comparability of
the financial data for the periods presented.

OVERVIEW

    We were organized on December 23, 1996 to become a leading provider of
telecommunications services for small and mid-sized businesses in our target
markets. From that date until the February 1998 acquisition of Valu-Line, our
predecessor, we were a development stage company with no revenue and principal
activities consisting of procuring governmental authorizations, raising capital,
hiring management and other key personnel, designing and developing our
telephone networks, acquiring equipment and facilities, negotiating resale and
interconnection agreements and pursuing acquisition opportunities. We had no
assets, liabilities or financial activity prior to January 1, 1997.

    The following is a summary of our major transactions and events.

FACTORS AFFECTING OPERATIONS


    REVENUE.  We generate most of our revenue from the sale of our voice and
data products, including local and long distance telephone service, Internet
access and customer premises equipment to small and mid-sized business customers
in various markets in Missouri, Kansas, Texas and Oklahoma. Revenue from local
services consists of charges for basic local service and custom calling
features. We offer local telephone service at a discount to the competing
incumbent provider of telecommunications services and offer long distance
service at flat per-minute rates. We offer customer premises equipment and
related services at negotiated rates generally consistent with other
competitors. We also offer data services in select markets primarily at flat
monthly rates. We expect that over the near term these services will continue to
be the principal components of our revenue.



    Our revenue consists of monthly recurring charges, usage charges and access
charges. Monthly recurring charges include the fees paid by our customers for
lines in service, additional features on those lines and collocation space.
Usage charges consist of fees paid for each call made generally measured by the
minute. Access charge revenue is generated for originating and terminating long
distance calls on our network. Additionally, revenue from customer premises
equipment sales is recognized upon project completion.


    OPERATING EXPENSES.  Our primary operating expenses are cost of services and
selling, general and administrative expenses.

    COST OF SERVICES.  Our cost of services includes the cost of leasing
unbundled network elements from the incumbent telephone company for combination
into Birch-branded voice services and purchasing the complete "bundle" of
traditional incumbent telephone company services for resale to our local service
subscribers. We lease local telephone network components to provide service for
our customers under an interconnection agreement with the incumbent telephone
company in our target markets. In markets where we have a local circuit switch,
we can avoid leasing the switch and related features from the incumbent
telephone company, which improves our gross margins.

    Incumbent telephone companies typically charge both a start-up fee as well
as a monthly recurring fee for use of their central offices for collocation of
transmission equipment. Physically collocating our transmission equipment in or
near existing incumbent telephone company switching offices allows us to combine
leased digital subscriber lines with our data transmission switches to provide
high speed data services and, eventually, voice and data services over a single
digital subscriber line. We also invest in transmission and distribution
electronics equipment associated with our switches. All of these costs are
reflected in our cost of services.

    Our primary long distance expenses are expenses associated with network
access and our leased long distance network. We purchase long distance capacity
from third party providers for all calls terminating outside of our network.

    Our primary expense associated with providing data services to our customers
is the cost of leasing transmission facilities. Our primary expense associated
with customer premises equipment is the cost of purchasing equipment from
manufacturers and labor for service and equipment installation.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Our selling, general and
administrative expenses include selling and marketing costs and customer
service, billing, corporate administration, personnel and network maintenance
expenses.

    We employ a direct sales force in each of our target markets. To attract and
retain a highly qualified sales force, we offer our sales personnel a
compensation package that emphasizes commissions. We expect to incur significant
selling and marketing costs as we expand our operations.

                                       24
<PAGE>
    We have implemented and continue to refine tailored systems for operations
support systems and other back office systems that provision and track customer
orders from point of sale to the installation and testing of service. Along with
the development costs of these systems, we also incur ongoing expenses for
customer service and billing systems. As our strategy stresses the importance of
personalized customer service, we expect that our customer service department
will become a larger part of our ongoing administrative expenses. We also expect
billing costs to increase as the number of our customers and the call volume
increase. We incur other costs and expenses, including the costs associated with
maintenance of our network, administrative overhead, office leases and bad debt.
We expect that these costs will grow significantly as we expand our operations
and that administrative overhead will be a large portion of these expenses
during the expansion phase of our business. However, we expect these expenses to
become a smaller percentage of our revenue as we build our customer base.

    We have experienced operating losses since inception as a result of efforts
to build our customer base, develop and construct network infrastructure, build
internal staffing, develop systems and expand into new markets. We expect to
continue to focus on increasing our customer base and geographic coverage.
Accordingly, we expect that cost of services, selling, general and
administrative expenses, and capital expenditures will continue to increase
significantly, all of which may have a negative impact on operating results. The
projected increases in capital expenditures will continue to generate negative
cash flows for at least the next several years as we develop and construct our
voice and data networks. We may also be forced to change our pricing policies to
respond to a changing competitive environment, and we cannot assure you that we
will be able to maintain our gross and operating margins. We cannot assure you
that growth in our revenue or customer base will continue or that we will be
able to achieve or sustain profitability or positive cash flows.

RESULTS OF OPERATIONS

    BIRCH TELECOM, INC.


    THREE MONTHS ENDED MARCH 31, 2000 COMPARED TO THREE MONTHS ENDED MARCH 31,
     1999



    REVENUE.  Revenue increased 123.8% to $23.8 million for the 2000 period
compared to $10.6 million for the 1999 period. The increase in revenue was
principally a result of new customer sales in new and existing markets and
partially due to a full quarter of revenue for Capital Communications
Corporation (acquired in March 1999) in the 2000 period. As a percentage of
total revenue, communications services were 89.4% for the 2000 period and 87.5%
for the 1999 period, and equipment sales were 10.6% for the 2000 period and
12.5% for the 1999 period.



    COST OF SERVICES.  Cost of services increased 118.8% to $17.3 million for
the 2000 period compared to $7.9 million for the 1999 period. The increase in
cost of services was primarily the result of associated revenue increases. Gross
margins increased 138.7% to $6.5 million (27.2% of revenue) for 2000 compared to
$2.7 million (25.5% of revenue) for 1999. The increase in gross margin as a
percentage of revenue was primarily the result of a greater percentage of
revenue being derived from higher margin facility-based local services as
compared to resold services in the 1999 period.



    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 155.6% to $21.2 million for the 2000 period
compared to $8.3 million for the 1999 period. The increase in expense was
primarily a result of supporting and attracting customers in new and existing
markets, market launches in Texas and having a full quarter of expense in the
2000 period for Capital Communications Corporation, which affected wages, rent
and advertising expense. Additionally, we had 1,130 employees at March 31, 2000
compared to 506 employees at March 31, 1999. EBITDA, a commonly used measure by
securities analysts of earnings before deducting interest, taxes, depreciation
and amortization, decreased 163.8% to a loss of $14.7 million for the 2000
period compared to a loss of $5.6 million for the 1999 period.


                                       25
<PAGE>

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
189.0% to $4.5 million for the 2000 period compared to $1.5 million for the 1999
period. The increase in depreciation and amortization was primarily attributable
to the depreciation of a larger base of network assets, the amortization of
intangible assets related to acquisitions and the amortization of financing
costs related to our senior debt facility.



    INTEREST.  Interest expense increased 23.8% to $4.6 million for the 2000
period compared to $3.7 million for the 1999 period. The increase in interest
expense was primarily a result of borrowings on our senior credit facility,
which began December 1999. Interest income decreased 50.8% to $446,000 for the
2000 period compared to $907,000 for the 1999 period. The decrease in interest
income is primarily a result of the maturity and sale of $16.1 million of
pledged securities for the payment of interest on the 14% senior notes.



    NET LOSS.  Net loss increased 134.9% to $23.3 million for the 2000 period
compared to $9.9 million for the 1999 period.



    YEAR ENDED DECEMBER 31, 1999 COMPARED TO YEAR ENDED DECEMBER 31, 1998



    REVENUE.  Revenue increased 132.1% to $60.5 million for 1999 compared to
$26.1 million for 1998. The increase in revenue was principally a result of new
customer sales in new and existing markets and the acquisitions of Capital
Communications Corporation in March 1999 and American Local in February 1999. As
a percentage of total revenue, communications services were 87.5% for 1999 and
83.5% for 1998, and equipment sales were 12.5% for 1999 and 16.5% for 1998.



    COST OF SERVICES.  Cost of services increased 145.5% to $46.4 million for
1999 compared to $18.9 million for 1998. The increase in cost of services was
primarily the result of associated revenue increases. Gross margins increased
96.9% to $14.2 million (23.4% of revenue) for 1999 compared to $7.2 million
(27.6% of revenue) for 1998. The decline in gross margin as a percentage of
revenue was principally the result of a greater percentage of revenue being
derived from resold local service during 1999 compared to 1998. Additionally,
long distance margins declined as a result of competitive pricing pressures.



    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 236.4% to $53.0 million for 1999 compared to
$15.8 million for 1998. The increase in expense was primarily a result of
supporting and attracting customers in new and existing markets, market launches
in Texas and the acquisitions of Capital Communications Corporation and American
Local each of which affected wages, rent and advertising expense. Additionally,
we had 935 employees at December 31, 1999 compared to 345 employees at
December 31, 1998. EBITDA decreased 353.6% to a loss of $38.9 million for 1999
compared to a loss of $8.6 million for 1998.



    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
369.2% to $10.8 million for 1999 compared to $2.3 million for 1998. The increase
in depreciation and amortization was primarily attributable to the depreciation
of network assets added in our markets and the amortization of intangible assets
related to acquisitions.


    INTEREST.  Interest expense increased 82.2% to $15.0 million for 1999
compared to $8.3 million for 1998. The increase in interest expense was
primarily a result of a full year of interest charges on our senior notes sold
in June 1998. Interest income remained virtually unchanged at $2.9 million in
1999 and 1998. Interest income is primarily derived from pledged securities
purchased in connection with our senior notes.


    NET LOSS.  Net loss increased 281.3% to $61.8 million for 1999 compared to
$16.2 million for 1998.


                                       26
<PAGE>

    YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997


    REVENUE.  Revenue was $26.1 million for 1998, resulting from the
acquisitions of Valu-Line, Boulevard, Telesource and TFSnet and new customer
sales from new markets. There was no revenue for 1997 because we were in the
developmental stage. In addition to revenue generated as a result of
acquisitions in 1998, revenue was generated from the sale of local telephone
services to new customers.


    COST OF SERVICES.  Cost of services and gross margin totaled $18.9 million
and $7.2 million, respectively, for 1998 as a result of the associated revenue
increases.



    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased $14.0 million to $15.8 million for 1998
compared to $1.8 million for 1997. The increase in expense was primarily a
result of the Valu-Line, Boulevard, Telesource and TFSnet acquisitions and
opening five new markets in 1998. Additionally, we expanded our engineering and
operations staff in preparation for switch deployment. EBITDA decreased 382.4%
to a loss of $8.6 million for 1998 compared to a loss of $1.8 million for 1997.



    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased to
$2.3 million for 1998 compared to $27,000 for 1997, most of which was
attributable to the fixed and intangible assets acquired in the Valu-Line,
Boulevard, Telesource and TFSnet acquisitions.


    INTEREST.  Interest expense was $8.3 million for 1998 primarily from
interest charges on the senior notes. There was no interest expense in 1997.
Interest income was $2.9 million in 1998 compared to $14,000 for 1997 primarily
as a result of invested funds received from the senior notes.


    NET LOSS.  Net loss was $16.2 million for 1998 compared to $1.8 million for
1997.


    VALU-LINE COMPANIES, INC. (PREDECESSOR COMPANY)


    YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996


    REVENUE.  Revenue increased 27.1% to $16.8 million for 1997 compared to
$13.2 million for 1996. The increase was primarily a result of entering the
local service market in March 1997 and long distance volumes increasing faster
than the decline in long distance pricing. Customer premises equipment sales
were 18% of revenue, or $3.0 million, for 1997 compared to 19.1% of revenue, or
$2.5 million, for 1996.


    COST OF SERVICES.  Cost of services increased 35.4% to $11.8 million for
1997 compared to $8.7 million for 1996. The increase was primarily a result of
associated revenue increases. Gross margin increased 11.0% to $5.0 million, or
29.5% of revenue, for 1997 compared to $4.5 million, or 33.8% of revenue, for
1996. The decrease in gross margin as a percentage of revenue was primarily a
result of low margins on resold local service, which started in March 1997.



    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 14.2% to $4.1 million for 1997 compared to
$3.6 million for 1996. The increase in expense was primarily a result of sales
commissions related to increased business volumes and increased customer service
expenditures associated with the commencement of local service. EBITDA decreased
1.7% to $892,000 for 1997 compared to $907,000 for 1996. The decrease in EBITDA
was primarily a result of the start-up costs associated with offering local
service.



    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased 9.6%
to $341,000 for 1997 compared to $311,000 for 1996.

LIQUIDITY AND CAPITAL RESOURCES


    At December 31, 1999, our current assets of $40.1 million exceeded current
liabilities of $25.4 million, resulting in working capital of $14.7 million
which represented a decrease of $35.0 million compared to working capital of
$49.7 million at December 31, 1998. At December 31, 1998, our current assets of
$61.1 million exceeded current liabilities of $11.4 million. The decrease in
working capital was primarily attributable to the use of cash to fund operations
and capital outlays for expansion of our network, support systems and back
office systems. At March 31, 2000, our current assets of $44.0 million exceeded
current liabilities of $26.3 million, resulting in working capital of
$17.7 million which represented an increase of $3.0 million compared to working
capital of $14.7 million at December 31, 1999. The increase in working capital
was primarily attributable to proceeds received from borrowings on our senior
credit facility to fund capital purchases. Pledged securities to satisfy
interest payments on our senior notes amounted to $23.7 million at March 31,
2000, $23.4 million at December 31, 1999 and $37.8 million at December 31, 1998.
At December 31, 1999, our total assets increased to $147.0 million from
$134.1 million at December 31, 1998. Our total assets increased to $166.1
million at March 31, 2000 from $147.0 million at December 31, 1999. These
increases were primarily the result of capital outlays for expansion of our
local and data networks and development of operations support systems and
automated back office systems.

$53.2 million for the year ended December 31, 1999 compared to $10.6 million for
the year ended December 31, 1998. Net cash used in operating activities was
primarily used to fund our net losses of $23.3 million for the period ending
March 31, 2000, $9.9 million for the period ending March 31, 1999,
$61.8 million for the year ended December 31, 1999 and $16.2 million for the
year ended December 31, 1998.



    INVESTING ACTIVITIES.  Net cash used in investing activities was
$14.5 million for the period ending March 31, 2000 compared to $11.8 million for
the period ending March 31, 1999. Net cash used in investing activities was
primarily used for the purchase of property and equipment related to the
expansion of our networks, support systems and back office systems, totaling
$14.0 million in the period ending March 31, 2000 and $7.0 million in the period
ending March 31, 1999. Additionally, $4.4 million was spent on acquisitions in
the period ending March 31, 1999. Net cash used in investing activities was
$31.8 million for the year ended December 31, 1999 compared to $67.1 million for
the year ended December 31, 1998. For the year ended December 31, 1999, net cash
used in investing activities was primarily used for the purchase of property and
equipment related to the expansion of our networks, support systems and back
office systems of $41.4 million and acquisitions of $4.8 million, partially
offset by net proceeds from the sale of pledged securities of $16.1 million for
the semi-annual interest payments on the senior notes. For the year ended
December 31, 1998, net cash used in investing activities was primarily used for
the purchase of pledged securities related to our senior notes of
$44.2 million, acquisitions of $7.8 million and purchases of property and
equipment related to the expansion of the network, support systems and back
office systems of $21.6 million, partially offset by net proceeds from the sale
of pledged securities of $7.7 million.



    FINANCING ACTIVITIES.  Net cash provided by financing activities was
$38.3 million for the period ending March 31, 2000 compared to net cash used in
financing activities of $974,000 for the period ending March 31, 1999. In the
period ending March 31, 2000, net cash provided by financing activities was
primarily a result of $40.0 million in proceeds from borrowings on our senior
credit facility. In the period ending March 31, 1999, net cash used in financing
activities was used for the repayment of debt. Net cash provided by financing
activities was $50.3 million for the year ended December 31, 1999 compared to
$117.3 million for the year ended December 31, 1998. For the year ended
December 31, 1999, net cash provided by financing activities was primarily a
result of $70.0 million in proceeds from


                                       28
<PAGE>

the sale of series D and series F preferred stock and borrowings of
$10.0 million under our senior credit facility, partially offset by the
redemption of series C and series E preferred stock of $18.6 million and the
payment of financing costs related to the series D and series F preferred stock
and on our senior credit facility of $8.8 million. For the year ended
December 31, 1998, net cash provided by financing activities was primarily a
result of proceeds of $114.7 million from the private offering of our senior
notes. These senior notes bear interest at a fixed rate of 14% per annum and are
due in June 2008. Subject to limitations, we may redeem a portion of these
senior notes prior to their maturity date if we pay a designated premium. The
indenture with respect to the senior notes contains a number of restrictive
financial and operational covenants with which we must comply.



    In February 2000, we increased the capacity of our $75.0 million senior
credit facility to $125.0 million. This credit facility provides for a
$25.0 million reducing revolver and $100.0 million in multi-draw term loans. The
revolver is available for general corporate purposes of our subsidiaries and the
term loans are to be used to finance telecommunications equipment, inventory,
network assets and back office systems. The senior credit facility is secured by
a perfected first priority security interest in substantially all of our assets
and capital stock of our subsidiaries and contains a number of financial and
operational covenants with which we must comply. Among other things, the
covenants require us to maintain specified levels of revenue, EBITDA, ratio
levels and access lines and restrict our ability to incur additional
indebtedness, pay dividends, enter into related party transactions or sell our
assets. We were in compliance with all covenants at March 31, 2000.



    In March 2000, an affiliate of KKR exercised its options to purchase an
additional $50.0 million of our series F preferred stock. The transaction was
funded and the associated shares were issued in April 2000.


    The development and expansion of our business will continue to require
significant capital to fund capital expenditures, working capital and debt
service and will generate negative operating cash flows.

    Our principal capital expenditure requirements will include:

    - the purchase, installation, and expansion of switches and transmission
      equipment for our local and data networks; and

    - the further development of operations support systems and automated back
      office systems.

We do not believe that the growth of our long distance and customer premises
equipment business will require significant capital expenditures.


    Our business plan calls for us to offer our services in an additional 35
markets before the end of 2001. We expect to commence service in the regions
served by Ameritech and BellSouth in 2001. We currently estimate that the cash
required to fund these capital expenditures will be approximately
$255.0 million over the next two years. We will need additional cash to fund our
working capital needs, debt service requirements and operating losses. Until we
begin to generate positive cash flow from operations, these liquidity
requirements will need to be financed with additional debt and equity capital.



    We are currently renegotiating the terms of our existing senior credit
facility, including increasing the size of the facility and making corresponding
changes to the financial covenants. In the event that the terms are
renegotiated, we believe that our current resources, including current
availability under our senior credit facility, together with the net proceeds
from the offering, will be sufficient to satisfy our liquidity needs for at
least the next 12 months. If we fail to renegotiate the existing terms of our
senior credit facility, we believe our current resources will be sufficient to
satisfy our liquidity needs associated with our significant expansion plan for
the next nine months. In addition, depending on prevailing capital market
conditions, we may choose to repurchase all or a portion of our senior notes.


                                       29
<PAGE>
    Thereafter, we will need substantial additional capital to finance our
business plan. If our plans or assumptions change, if our assumptions prove to
be inaccurate, or if we experience unexpected costs or competitive pricing
pressures, we will be required to seek additional capital sooner than we
currently expect. In particular, if we elect to pursue acquisition opportunities
or open additional markets, our cash needs may increase substantially. We cannot
assure you that our current projection of cash flow and losses from operations,
which will depend upon numerous future factors and conditions, many of which are
outside of our control, will be accurate. Actual results will almost certainly
vary materially from our current projections. The cost of expanding our network
services and sales efforts, funding other strategic initiatives and operating
our business will depend on a variety of factors, including, among other things:

    - the number of subscribers and the services for which they subscribe;

    - the nature and penetration of services that we may offer;

    - regulatory and legislative developments; and

    - the response of our competitors to their loss of customers to us and to
      changes in technology.

    We intend to seek additional debt and equity financing to fund our future
liquidity needs. We cannot assure you that we will be able to raise additional
capital on satisfactory terms or at all. If we decide to raise additional funds
through the incurrence of debt, our interest obligations will increase and we
may become subject to additional or more restrictive financial covenants. In
addition, the terms of our senior credit facility and our senior notes each
restrict our ability to obtain additional debt financing. If we decide to raise
additional funds through the issuance of equity, the ownership interests
represented by the common stock will be diluted. In the event that we are unable
to obtain additional capital or to obtain it on acceptable terms or in
sufficient amounts, we may be required to delay the development of our network
and business plans or take other actions that could materially and adversely
affect our business, operating results and financial condition.

IMPACT OF THE YEAR 2000 ISSUE

    The Year 2000 issue results from computer programs being written using two
digits rather than four to define the year. Any of our computer programs or
systems, or those of our suppliers, that have date-sensitive software may
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in a system failure or miscalculation causing the disruption of
operations, including among other things:

    - a temporary inability to process transactions;

    - a temporary inability to send invoices;

    - a temporary inability to engage in normal business activities; and

    - interruptions of customer care.

    We did not experience any problems on January 1, 2000 and to date, we have
not experienced, nor are we aware of, any material Year 2000 issues with any of
our internal systems or our services, and we do not anticipate experiencing any
issues in the future. Further, we are unaware of any issues with our vendors,
suppliers or customers that will materially affect us.

    We believe that we have identified all major computers, software
applications and related equipment used in connection with our internal
operations that will need to be modified, upgraded or replaced to minimize the
possibility of a material disruption to our business. We have completed
assessing the potential impact of Year 2000 issues on these computers, equipment
and applications and have modified, upgraded and replaced major systems that we
believe have Year 2000 issues.

                                       30
<PAGE>
    In addition to computers and related information, operation, and network
systems, the operation of office systems, facilities and equipment, such as fax
machines, security systems and other common office devices, may have Year 2000
issues that have not yet surfaced. We will continue to monitor the performance
of these office systems, equipment and facilities.

    We expect that we will be able to resolve any significant Year 2000 issues
we have identified with third party suppliers of components of
telecommunications services and our key subcontractors. However, because we have
no control over the actions of these parties, they may not remediate any or all
of the Year 2000 issues identified. Any failure of any of these third parties to
timely resolve Year 2000 issues with either their products sold to us, or their
systems could have a material adverse effect on our business, operating results
and financial condition. In addition, the delivery of our services also depends
on the operation of the networks of many local exchange carriers and long
distance carriers with whom we must interact as part of our normal business
operations, but with whom we do not have formal contractual arrangements.
Consequently, failure of these carriers' networks to fully operate as a result
of Year 2000 issues could also affect our operations. To our knowledge, none of
these networks experienced any problems on or since January 1, 2000.

    Our total cost to date to proactively address our Year 2000 issues has not
been material. The cost of addressing Year 2000 issues is reported as a general
and administrative expense.

    We believe we identified and resolved all Year 2000 issues that could
materially and adversely affect our business operations. However, for the
reasons discussed above, we believe that it is not possible to determine with
complete certainty that all Year 2000 issues affecting us have been identified
or corrected and we may not know that this is true for several months. As a
result, we believe that the following consequences are possible:

    - operational inconveniences and inefficiencies for us that will divert our
      management's time and attention and our financial and human resources from
      ordinary business activities;

    - business disputes and claims for pricing adjustments or penalties by our
      customers due to Year 2000 issues, which we believe will be resolved in
      the ordinary course of business; and

    - business disputes alleging that we failed to comply with the terms and
      conditions of contracts or industry standards of performance that result
      in litigation or contract termination.

    We developed contingency plans to be implemented if our efforts to identify
and correct Year 2000 issues affecting our internal systems were ineffective. We
have adopted the Year 2000 contingency plans as our standard operational
contingency plans. Our contingency plans are designed to minimize the
disruptions or other adverse effects. Our plans include:

    - accelerated replacement of affected equipment or software;

    - short to medium-term use of backup equipment and software;

    - increased work hours for our personnel; and

    - use of contract personnel to correct on an accelerated schedule any Year
      2000 issues that arise or to provide manual workarounds for information
      systems.

    Our implementation of any of these contingency plans could require us to
expend additional funds and could have a material adverse effect on our
business, operating results and financial condition. Our efforts in this regard,
if necessary, will be to minimize expense associated with the implementation and
use of any contingency planning with our objective to employ the least costly
plan necessary to address the relevant operational issues.

                                       31

IMPACT OF INFLATION

    We do not believe that inflation has had a significant impact on our
consolidated operations.

SEASONALITY

    Our business is not considered to be seasonal.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK


    We do not have operations subject to risks of foreign currency fluctuations,
nor do we use derivative financial instruments in our operations or investment
portfolio. Our earnings are affected by changes in interest rates as our
long-term debt under our senior credit facility has variable interest rates
based on either the prime rate or LIBOR. Our exposure to variable interest rate
risk during 1999 was insignificant due to our level of floating rate borrowings.
However, if interest rates for our long-term debt under our senior credit
facility had averaged 10% more and the full amount available under our senior
credit facility had been outstanding for the entire year, our interest expense
would have increased, and loss before taxes would have increased by
$12.5 million for the year ended December 31, 1999. These amounts are determined
by considering the impact of the hypothetical interest rates on our borrowing
cost and outstanding debt balances. These analyses do not consider the effects
of the reduced level of overall economic activity that could existing in this
environment. Further, in the event of a change of this magnitude, management
would likely take actions to further mitigate our exposure to the change.
However, due to the uncertainty of the specific actions that would be taken and
their possible effects, the sensitivity analysis assumes no changes in our
financial structure. We had $114.7 million of senior notes outstanding as of
March 31, 2000. These notes bear interest at a fixed rate of 14% and are not
subject to risk from interest rate fluctuations.


RECENTLY ISSUED ACCOUNTING STANDARDS


    In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities," which supersedes SFAS No. 80,
"Accounting for Futures Contracts," SFAS No. 105, "Disclosure of Information
About Financial Instruments with Off-Balance-Sheet Risk and Financial
Instruments with Concentration of Credit Risk," and SFAS No. 119, "Disclosures
about Derivative Financial Instruments and Fair Value of Financial Instruments,"
and also amends some aspects of other SFAS's previously issued. SFAS No. 133
establishes accounting and reporting standards for derivative instruments and
hedging activities. It requires that an entity recognize all derivatives as
either assets or liabilities in the balance sheet and measure those instruments
at fair value. SFAS No. 133 is effective for our consolidated financial
statements for the year ending December 31, 2001. We do not expect the impact of
SFAS No. 133 to be material in relation to our consolidated financial
statements.



    In December 1999, the SEC issued Staff Accounting Bulletin (SAB) No. 101,
"Revenue Recognition in Financial Statements." SAB No. 101 provides guidance on
the recognition, presentation and disclosure of revenue in financial statements.
SAB No. 101 is effective for our consolidated financial statements beginning in
the second quarter of 2000. We do not expect the impact of SAB No. 101 to have a
material effect in relation to our consolidated financial statements.



    In March 2000, the FASB issued Interpretation No. 44, "Accounting for
Certain Transactions Involving Stock Compensation: An Interpretation of
Accounting Principles Board (APB) Opinion No. 25" (the FASB Interpretation). The
FASB Interpretation poses and answers 20 separate questions dealing with APB
No. 25, "Accounting for Stock Issued to Employees," implementation practice
issues. The FASB Interpretation will be effective beginning July 1, 2000, and we
are currently determining its impact in relation to our consolidated financial
statements.

                                    BUSINESS

OVERVIEW


    We are a rapidly growing integrated communications provider. We seek to
become the leading provider of telecommunications services for small and
mid-sized businesses in each of the cities we serve. We offer state-of-the-art
telecommunications services to our customers, who today are located throughout
Missouri, Kansas, Texas and Oklahoma. These voice and data service offerings
include local and long distance telephone service, Internet access, web hosting,
integrated voice and data transmission over broadband lines and customer
premises equipment sales and services. We offer these services to our customers
through a combination of leased and owned network facilities. We are currently
deploying collocations and transmission equipment throughout our markets to
deliver digital subscriber line service, which will support dedicated high-speed
Internet access and eventually voice services. We expect to have over 130
collocations operational by the end of this year. Our revenue for the year ended
December 31, 1999 was $60.5 million, a 132% increase over 1998 and was
$23.8 million for the quarter ended March 31, 2000, a 124% increase over the
equivalent period in 1999.


BUSINESS STRATEGY

    We believe that our business is poised for rapid expansion and that our
experienced management team is well prepared to execute our focused business
strategy. The key elements of our strategy include:

    FOCUSING ON SMALL AND MID-SIZED BUSINESS CUSTOMERS

    We focus on meeting the needs of small and mid-sized businesses in each of
    the cities we serve. Our tailored service offerings, direct sales model, and
    proactive customer service approach allow us to differentiate ourselves and
    achieve significant penetration into this very large, established customer
    base. We believe small and mid-sized businesses have not received a
    satisfying level of attention from the incumbent telephone companies, are
    unaware of their telecommunications network options and value our
    consultative, direct sales approach.

    PROVIDING COMPLETE SERVICE PACKAGES THAT ARE TAILORED TO OUR CUSTOMERS

    Our service offerings are specifically designed for the needs of our target
    customers. We provide simplified, feature-rich packages of services,
    superior value and a single source for all of our customers' networking
    requirements, all conveniently billed on a single invoice. Our service
    offerings include features offered in packages that we believe are not
    generally available from other providers. Our packages are priced to offer
    savings of 10% to 40% from comparable services provided by the incumbent
    telephone company. Our direct sales representatives consult with our
    customers in person and assist them in selecting service packages
    appropriate for their needs.

    CREATING A STRONG BRAND PRESENCE

    We have quickly achieved a high level of brand awareness in our markets
    through an aggressive multi-media advertising campaign targeted at the
    incumbent telephone company. Our marketing efforts include billboard, radio
    and print advertising, as well as sponsorship of major local events,
    affiliations with local organizations and direct mailings. We believe we
    have been able to achieve a higher level of brand awareness in our markets
    than any other new market entrants. We plan to use our proven marketing and
    advertising strategy to help us achieve rapid and deep penetration in each
    new market we enter.

    DEPLOYING A DIRECT SALES FORCE IN EACH OF OUR MARKETS


    We deploy a large locally-based sales force focused on achieving a
    significant market share in each of our markets. We believe that our
    extensively marketed brand name, visible local presence,


                                       33
<PAGE>

    readily available services and emphasis on personal customer service have
    enabled our 196-person sales force to achieve high levels of productivity
    and quickly penetrate new markets.


    INVESTING IN INDUSTRY-LEADING, SCALABLE BACK OFFICE SYSTEMS

    We believe our state-of-the-art billing and operating systems are capable of
    supporting a significant number of lines. These systems, which include
    Saville Convergent Billing Platform-TM-, MetaSolv Telecom Business
    Solution-TM- and Harris Network Management-TM-, have already withstood the
    test of high volumes and rapid growth within our operation. Over the past
    year, we have expanded our provisioning capacity from 3,000 lines per month
    to nearly 15,000 lines per month and believe that our existing
    infrastructure can support continued capacity increases.

    MAINTAINING MAXIMUM NETWORK FLEXIBILITY

    - INTEGRATING DATA AND VOICE NETWORK SERVICES. By integrating both data and
      voice services, we believe we will be able to deliver a broadband digital
      subscriber line connection to a significant percentage of our customers.
      We believe this integration will yield bandwidth flexibility to our
      customers and the strategic advantage of an improved product with reduced
      monthly costs.

    - CAPITALIZING ON OUR UNBUNDLED NETWORK ELEMENT PLATFORM. We provide service
      to a majority of our customers by leasing substantially all of the
      unbundled network elements from the incumbent telephone company and using
      our advanced back office systems to combine these elements into integrated
      Birch-branded voice services. This platform has allowed us to offer voice
      services to customers located virtually anywhere in our markets and
      achieve high gross margins and superior returns on incremental capital
      invested. UNE-P allows us to minimize current capital expenditures and
      maintain design flexibility for the next generation of telecommunications
      technology.

    - POSITIONING FOR MASS DEPLOYMENT OF BROADBAND. Our network objective is to
      mass-deploy broadband facilities (primarily digital subscriber lines) that
      support both voice and data over a single line. We are implementing
      collocations at central offices of the incumbent telephone company
      throughout our markets and intend to deploy packet switches that can
      handle voice and data over a single line as soon as they become available.

    EXPANDING OUR GEOGRAPHIC REACH


    We currently serve 23 markets that have populations ranging in size from
    95,000 to 4.5 million, and we intend to offer our services in 35 additional
    markets before the end of 2001. We expect to commence service in the regions
    served by Ameritech and BellSouth in 2001. We have developed systems,
    network capabilities and an experienced sales force and customer service
    team that position us to rapidly penetrate these new markets and regions.


    GROWING THROUGH ACQUISITIONS

    We have completed six acquisitions since our inception in December 1996 for
    total consideration of $27.7 million. From time to time, we consider making
    additional acquisitions to further complement our service capabilities or
    expand our geographic scope. We believe we have been highly successful in
    integrating our acquisitions. With our diverse sources of capital and highly
    sophisticated stockholders and board members, we believe we are well
    positioned to continue to evaluate a variety of these opportunities and make
    selected acquisitions where appropriate.

TELECOMMUNICATIONS SERVICES

    OFFERED SERVICES

    We design our voice and data services to appeal to small and mid-sized
businesses that value simple integrated communications service packages from a
single provider. We believe that the key to attracting and retaining our target
customers is to offer a comprehensive set of services. These services

                                       34
<PAGE>
include voice offerings of local lines, features and long distance at flat
per-minute rates, and data offerings including dedicated digital subscriber line
and dial-up Internet access, web hosting and other data services.

    We divide our service offerings generally into three broad categories:
voice, Internet and web hosting. The chart below sets forth the different
service packages and options provided within each of these categories.

    DELIVERY OF SERVICES

    UNE-P

    We lease all of the unbundled network elements necessary to provide service
from the incumbent local exchange carriers. We believe that our UNE-P strategy
allows us to enter into new markets more quickly than if we had initially
deployed our own network facilities. This strategy also reduces initial capital
requirements in each market, allowing us to focus our capital resources
initially on the critical areas of sales, marketing and operations support
systems. In addition, we believe UNE-P will allow us to avoid further deploying
circuit switches and maintain design flexibility for the next generation of
telecommunications technology.

    BROADBAND

    We intend to install digital subscriber line equipment at our collocation
sites, at our switch sites and at our customers' locations. We believe this
equipment will allow us to deliver multiple voice calls and data traffic over a
single, standard telephone line and is expected to provide us with substantial
cost savings. Using DSL technology, we believe we will increase the amount of
information we carry on a standard telephone line, which we refer to as
bandwidth, to up to 1.5 million bits per second. The bandwidth is the equivalent
of 24 regular voice telephone lines. Our digital subscriber line equipment will
be programmed to allocate the available bandwidth.

    We believe this technology will reduce our costs since we will lease a
reduced number of standard telephone lines per customer from the incumbent
carrier. For example, if a customer today has eight voice lines, we must order
from and provision through the incumbent carrier eight individual standard
telephone lines. If the same customer were to buy our service which uses digital
subscriber line technology, we would only order and provision one standard
telephone line from the incumbent carrier. Also, we expect that future products
and services designed to take advantage of the increased bandwidth provided by
digital subscriber line technology will allow us to generate incremental revenue
with attractive margins.

    CUSTOMER PREMISES EQUIPMENT

    We offer our customers equipment they need to run their internal phone
systems, including data routers and wiring, telephone equipment and integrated
access devices. We also sell and service standard key systems, private branch
exchanges and voice-mail systems, and provide inside-wire services for
commercial accounts, including wiring for data networking, in Kansas and
Missouri. We are an authorized equipment distributor for Northern
Telecom, Inc., Toshiba America Information Systems, Inc., NEC America, Inc.,
Executone Information Systems, Inc. and Tadiran Electronic Industries, Inc.

SALES AND MARKETING

    SALES


    As of May 31, 2000, we had a direct sales force of 196 representatives
operating from 23 offices throughout Missouri, Kansas and Texas. Of these
representatives, 26 were primarily selling customer premises equipment and the
remaining 170 were selling local, long-distance, data and Internet services. The
sales representatives are supported by sales managers. Over the next 12 months,
we plan to increase our sales staff in existing markets and open additional
sales offices in Ameritech's and BellSouth's regions. We supplement our sales
efforts through brand awareness efforts including local and regional
advertising, public relations and local sponsorships.


    We seek to convert small to mid-sized business customers from the incumbent
provider of telecommunications services in their market and to establish a
solid, long-term relationship with them.

                                       36
<PAGE>
Our sales representatives meet with prospective customers to gain a thorough
understanding of their business and telecommunications requirements. Sales
representatives then suggest alternatives for operation enhancements and cost
savings based on our service packages.

    We compensate our sales representatives with a competitive base salary,
stock options and commissions based on sales results. We use a revenue-based
commission structure that enables us to attract productive sales people
experienced in disciplined, activity-based sales. This commission structure is
based on incremental revenue and is not subject to a cap.

    We do not actively market to residential customers. Nonetheless, we have
found that our sales and promotional efforts attract residential customers, many
of whom are owners or employees of businesses using our telecommunication
services. Residential customers call our customer service center to receive
forms to apply for service. We do not pay sales commissions for residential
sales.

    ADVERTISING AND PROMOTION

    We conduct extensive marketing campaigns in our local markets. We make use
of advertising and public relations to attract small to mid-sized business
customers and contrast our service attributes with Southwestern Bell's. Our
marketing campaign includes billboard, radio and print advertising, as well as
sponsorship of major local events, affiliations with local organizations and
direct mailings focusing on public relations. We also believe that our
willingness to serve residential customers--unlike many other competitive local
exchange carriers--creates greater interest in our development among the news
media and general public. In the past, our market launches have attracted
extensive local media coverage.

    In keeping with our philosophy of being accessible to our customers, we
establish local sales and customer service offices in most of the cities and
towns that we serve. In many of these cities and towns, we are the only provider
of local telephone service that maintains an office. Our offices are open to
walk-in traffic and often are located in high-profile areas.

    Because we are able to deliver a comprehensive set of products to our target
customers, we believe we have strong customer loyalty. Our customer churn rates
have generally been less than 1.5% per month.

    PRICING


    We do not intend to position ourselves as the cheapest provider of services,
especially long distance services. We target customers who value the convenience
of our service offerings and personalized customer service. Customers who have
the highest price sensitivity are likely to move frequently among providers,
driving up churn rates. However, we do set our pricing so that our local
business customers can generally save from 10% to 40% as compared to the
incumbent provider's rates. Internet, long distance and customer premises
equipment are generally priced at rates competitive with that of other service
providers.

BACK OFFICE SYSTEMS

    Back office systems refer to the hardware and software systems that support
the primary functions of our operations, including:

    - order entry and provisioning;

    - billing;

    - data center;

    - trouble management; and

    - sales support.

                                       38
<PAGE>
    Our goal is to have a back office that allows us to convert our customers'
service from their current local providers to our networks easily and quickly.
Over time, we strive to have "flow through" provisioning capabilities, allowing
services to be implemented through a single systems interface that updates all
ordering, inventory, billing and monitoring systems.

    We have implemented the primary elements of our back office, including order
entry, provisioning, billing and network management. We believe we have selected
the best application for each function. The following table describes our key
back office systems that provide crucial operational functionality, their
purpose and timeline for implementation.

</TABLE>


    ORDER ENTRY AND PROVISIONING

    Order entry involves the initial loading of customer data into our
information systems. Currently, our sales executives take orders and our
customer care and provisioning representatives load the initial customer
information into our Saville billing system and our MetaSolv provisioning
system. We intend to increase the efficiency and data accuracy of these
provisioning activities by implementing a sales force automation system to be
combined with Saville CBP and MetaSolv TBS through application integration
middleware. This system will facilitate entry of sales orders from the sales
offices and transmit relevant account and order information to Saville CBP and
MetaSolv TBS. Implementing this system will eliminate several manual steps in
the provisioning process.

    We use the MetaSolv TBS system to manage and track the timely completion of
each step in the provisioning process. When MetaSolv is coupled with
capabilities of the DSET electronic bonding system, we believe we will be able
to submit orders to external business partners, including Southwestern Bell,
electronically, thereby minimizing implementation time, coordination
complexities and installation costs. Currently, we provision orders
electronically through Southwestern Bell's electronic provisioning system, or
Toolbar.

                                       39
<PAGE>
    In addition to the cost benefits associated with the electronic installation
of access lines and inventory management system, the MetaSolv system improves
our internal processes in various other ways, including:

    - directing electronic customer orders to the appropriate employee,
      prompting them to complete required provisioning tasks, including network
      component assignments and management of outside vendor activities; and

    - tracking order progress and alerting operations personnel of steps
      required to fulfill orders within standard work intervals.

    The MetaSolv TBS system enables a customer care coordinator to keep an
installation on schedule and notify the customer of any potential delays. Once
an order has been completed, we update our billing system to initiate billing of
installed services.

    BILLING

    The Saville billing system provides our customers with a consolidated
invoice for all of our services. Customer calls generate billing records that
are transmitted from the call records to the Saville billing system. These
records are then processed by the billing software, which calculates usage
costs, integrates fixed monthly charges, calculates taxation and provides the
data necessary to create a simple customer invoice. We provide invoice
information to a third party printer, which prepares and distributes bills to
our customers. Our customers pay us directly.

    This Saville system allows us to add advanced features such as special
discounts based on call volume, or number of services used, complex local
taxation and discrete billing options by type of service ordered. We believe
these features are exceptionally important given our sophisticated client base.

    TROUBLE MANAGEMENT

    We use MetaSolv TBS, a customer care and trouble management system, to
provide high quality customer service. Our trouble management system is
integrated into the operational support system. It enables our customer care
personnel to track customer problems proactively, assign repair work to the
appropriate technical teams and provide employees and management access to
comprehensive reports on the status of service activity.

    NETWORK MANAGEMENT

    We use the Harris Network Management system to continuously monitor and
operate our switch networks. The information provided by the Harris system
allows our network operations staff to quickly repair problems in the networks,
thereby eliminating or minimizing impacts to our customers.

    SOUTHWESTERN BELL TOOLBAR

    Toolbar is the Southwestern Bell end-user interface system that allows our
customer service, trouble management and service provisioning representatives to
access the Southwestern Bell operating systems. Toolbar allows us to send local
service requests to receive order commitments back from, reserve new telephone
numbers with, view an order's status at, and test or report customer problems to
Southwestern Bell.

    DATA CENTER


    During the second quarter 2000, we began operating an 8,000 square foot data
center in Kansas City, Missouri. We believe this center has sufficient space to
support significant increases in our access lines, customers and employees.


                                       40
<PAGE>
NETWORK FACILITIES

    LEASED FACILITIES

    During 1999, we began to lease substantially all of the network elements
from Southwestern Bell and combine these elements into integrated Birch-branded
voice services without deploying a switch. By using UNE-P, we are able to offer
our services to a broader geographical area than we can by using our own
switches. Many of our competitors are limited to serving customers that are
located near their facilities. UNE-P allows us to serve many customers in
disparate geographic areas.

    Where we have installed switches, we lease transmission facilities from
Southwestern Bell to connect our switches to our collocated equipment in
Southwestern Bell's central offices and to unbundled loops. Given the current
capacity of existing local networks, we do not anticipate having to build local
transmission facilities in the future. Similarly, we believe that the capacity
of existing long-distance networks renders direct ownership of long distance
transmission facilities unnecessary.

    Leasing, rather than building, facilities supports our strategy of rapid
local market development because our sales activity is not constrained by
network expenditures. Moreover, by leasing transmission facilities, we can offer
our services throughout a metropolitan area and we are not constrained by the
limited number of locations in which we could build transmission facilities.

    OWNED FACILITIES

    We deploy data transmission packet switches in most of our markets. We use
these packet switches to transmit data over our leased transmission lines and
plan to use these packet switches to transmit our long distance voice traffic
once our conversion plan is implemented.

    We currently operate local/long distance circuit switches in Kansas City and
St. Louis, Missouri and Wichita, Kansas. We do not intend to deploy more circuit
switches because we believe voice-capable packet switches will be more
economical to operate in the future. Additionally, we collocate our electronic
equipment at Southwestern Bell's central offices to support future digital
subscriber line services and existing circuit switches. Collocation allows us to
connect to transmission lines we lease from Southwestern Bell.

    At the customer's premises, we connect unbundled loops directly to
customer-owned equipment. We may also deploy electronic equipment (intelligent
channel banks or access servers) that concentrate data and voice traffic. This
enables us to obtain higher capacity from the transmission line of the incumbent
local exchange carrier.

OPERATIONS

    EMPORIA AND KANSAS CITY SERVICE CENTERS

    Our service centers in Emporia, Kansas and Kansas City, Missouri are
critical to our ability to offer excellent service and to support growth. These
service centers process orders, interface with Southwestern Bell's operational
support systems and provide customer service, trouble resolution, billing and
collection services for our customers. These service centers provide rapid,
human assistance rather than the automated, cumbersome customer interface
currently used by many telecommunications providers.

    FIELD TECHNICAL OPERATIONS

    Our field technicians service our facilities and customer-owned facilities.
These technicians install, repair and maintain digital switches, transmission
equipment, private branch exchanges, key systems, data equipment and inside
wiring, including wiring for data networking. We believe field technicians are
often the most respected source of telecommunications advice for small and
mid-sized business customers. We believe that having a skilled, in-demand group
of technicians supports our customer base, provides expertise for data
deployment and strengthens customer loyalty.

                                       41
<PAGE>
COMPETITION

    The telecommunications industry is highly competitive. We believe we compete
principally on the basis of customer service, accurate billing, variety of
services and, to a lesser extent, pricing levels and less complex pricing
structures. Our ability to compete effectively depends upon our continued
ability to maintain high quality, market-driven services at prices generally
equal to or below those charged by competitors. To maintain our competitive
posture, we believe that we must be able to provide high quality integrated
communications services and be positioned to reduce our prices in response to
potential competition. Any of these reductions could adversely affect us. Many
of our current and potential competitors have financial, technical, marketing,
personnel and other resources, including brand name recognition, substantially
greater than ours, as well as other competitive advantages over us.

    INCUMBENT TELEPHONE COMPANIES

    In our existing markets, we compete principally with Southwestern Bell. As a
recent entrant in the telecommunications services industry, we may not achieve a
significant market share for any of our services in our markets. In particular,
Southwestern Bell and other local telephone companies have long-standing
relationships with their customers, have financial, technical and marketing
resources substantially greater than ours, have the potential to subsidize
competitive services with revenue from a variety of businesses and currently
benefit from existing regulations that favor these incumbent local exchange
carriers over us in some respects. While recent regulatory initiatives, which
allow competitive local exchange carriers such as us to interconnect with
incumbent local exchange carrier facilities, provide increased business
opportunities for us, these interconnection opportunities have been, and likely
will continue to be, accompanied by increased pricing flexibility for and
relaxation of regulatory oversight of the incumbent local exchange carriers.
Future regulatory decisions could grant incumbent local exchange carriers
increased pricing flexibility or other regulatory relief. These initiatives
could also have a material adverse effect on us.

    COMPETITIVE LOCAL EXCHANGE CARRIERS/INTEREXCHANGE CARRIERS/OTHER MARKET
     ENTRANTS


    We also face competition from other current and potential market entrants.
These market entrants include long distance carriers that compete with our long
distance services and seek to enter, reenter or expand into the local exchange
market. AT&T, GTE, WorldCom and Sprint are among these carriers. Competitive
local exchange carriers, resellers of local exchange services, competitive
access providers, cable television companies, electric utilities, microwave
carriers, wireless telephone system operators and private networks built by
large end users also compete with us. In addition, consolidation and strategic
alliances within the telecommunications industry, or the development of new
technologies could put us at a competitive disadvantage. Not only does the
Telecommunications Act impose regulatory requirements on all local
telecomunications service providers, but it also grants the FCC expanded
authority to reduce the level of regulation applicable to any telecommunications
service provider, including any incumbent telecommunications service providers.
The manner in which these provisions of the Telecommunications Act are
implemented and enforced could have a material adverse effect on our ability to
compete successfully against incumbent local exchange carriers and other
telecommunications service providers.


    The changes in the Telecommunications Act radically altered the market
opportunity for new telecommunications service providers. Because the
Telecommunications Act requires local exchange carriers to unbundle their
networks, new telecommunications service providers are able to rapidly enter the
market by installing switches and leasing trunk and loop capacity. Newer
providers, like us and some competitors that we may encounter in some of our
markets, will not have to replicate existing facilities until traffic volume
justifies building them, and can be more opportunistic in designing and
implementing networks.

                                       42
<PAGE>
    In addition to the new telecommunications service providers, interexchange
carriers and other competitors listed above, we may face competition from other
market entrants such as electric utilities, cable television companies and
wireless companies. Electric utilities have existing assets and low cost access
to capital which could allow them to enter a market rapidly and accelerate
network development. Cable television companies are entering the
telecommunications market by upgrading their networks with fiber optics and
installing facilities to provide fully interactive transmission of broadband
voice, video and data communications. Finally, wireless companies intend to
develop wireless technology for deployment in the United States as a broadband
substitute for traditional wireline local telephones. Some Internet companies
are also developing applications to deliver switched voice communications over
the Internet.

    LONG DISTANCE SERVICES

    The long distance telecommunications industry has numerous entities
competing for the same customers and a high churn rate, as customers frequently
change long distance providers in response to offerings of lower rates or
promotional incentives. Prices in the long distance market have declined
significantly in recent years and are expected to continue to decline. Our
primary competitors are the major interexchange carriers and resellers of long
distance services. We believe that pricing levels are a principal competitive
factor in providing long distance service; however, we seek to avoid direct
price competition by packaging long distance service, local service, customer
premises equipment and Internet access service together with a simple pricing
plan.

    CUSTOMER PREMISES EQUIPMENT

    We compete with numerous equipment vendors and installers and
telecommunications management companies for the sale of customer premises
equipment and related services. We generally offer our products at prices
consistent with other providers and differentiate our service through our
product packages.

    DATA/INTERNET SERVICES

    The Internet services market is highly competitive, and we expect that
competition will continue to intensify. Internet service, meaning both Internet
access and on-line content services, is provided by Internet service providers,
satellite-based companies, long distance carriers and cable television
companies. Many of these companies provide direct access to the Internet and a
variety of supporting services to businesses and individuals. In addition, many
of these companies, such as America Online, Inc., MSN, Prodigy Services Company
and WebTV Networks, offer on-line content services consisting of access to
closed, proprietary information networks. Long distance companies, among others,
are aggressively entering the Internet access markets. Long distance carriers
have substantial transmission capabilities, traditionally carry data to large
numbers of customers and have an established billing system infrastructure that
permits them to add new services. Satellite companies are offering broadband
access to the Internet from desktop PCs. Cable companies are starting to provide
Internet services using cable modems to customers in major markets. Many of
these competitors have substantially greater financial, technological,
marketing, personnel, name-brand recognition and other resources than those
available to us.

EMPLOYEES


    At May 31, 2000, we employed 1,288 persons. Additionally, we occasionally
hire temporary employees. We are not party to any collective bargaining
arrangements and believe that our relationship with our employees is good.


                                       43
<PAGE>
PROPERTIES


    We lease 43,783 square feet in office space in Kansas City, Missouri for our
corporate headquarters. This lease expires December 2006. Recently, we leased an
additional 87,651 square feet of office space in Kansas City to expand our
corporate headquarters. This lease expires February 2008. In Emporia, Kansas, we
own two buildings totaling 58,500 square feet for our customer care center and
provisioning divisions. In addition, we lease an aggregate of 21,175 square feet
to house our four circuit switches in Kansas City and St. Louis, Missouri and
Wichita, Kansas. These leases expire March 2003, November 2008, August 2005 and
June 2008, respectively. We also lease space in 34 buildings, totaling
approximately 208,022 square feet, in Missouri, Kansas, Texas and Oklahoma for
our sales offices and customer premises equipment sites. These leases are
generally leased on a month-to-month or annual basis.


LEGAL PROCEEDINGS

    From time to time, we may be involved in claims or litigation that arise in
the normal course of business. We are not a party to any legal proceedings
which, if decided adversely, would have a material adverse effect on our
business or financial condition or results of operations.

                                   REGULATION

REGULATORY OVERVIEW

    We are subject to regulation by federal, state and local government
agencies. Historically, the FCC had jurisdiction over interstate long distance
services and international services, while state regulatory commissions had
jurisdiction over local and intrastate long distance services.

    In 1996, Congress passed the Telecommunications Act of 1996, opening the
local market to competition and allowing the Bell operating companies to compete
for the first time in the long distance market within their local service
regions once specified conditions were met. The Telecommunications Act
fundamentally changed the way telecommunications is regulated in this country.
The FCC was given a major role in writing and enforcing the rules under which
new competitors could compete in the local marketplace. Those rules, coupled
with additional rules and decisions promulgated by the various state regulatory
commissions, form the core of the regulatory framework under which we operate in
providing local exchange service.

    With a few limited exceptions, the FCC continues to retain exclusive
jurisdiction over our provision of interstate and international long distance
service, and the state regulatory commissions regulate our provision of
intrastate local and long distance service. Additionally, municipalities and
other local government agencies may regulate limited aspects of our business,
such as use of government-owned rights-of-way, and may require permits such as
zoning approvals and building permits.

    In the aftermath of the Telecommunications Act, the regulation of the
telecommunications industry has been in a state of flux. The FCC and state
regulatory commissions have adopted many new rules to implement this legislation
and encourage competition, but that implementation is ongoing. The following
summary of regulatory developments does not purport to describe all current and
proposed federal, state and local regulations and legislation affecting the
telecommunications industry. Many of these are currently the subject of judicial
proceedings, legislative hearings and administrative proposals, any of which
could change, in varying degrees, the manner in which this industry operates. We
cannot predict at this time the outcome of these proceedings or their impact
upon the telecommunications industry or on us.

THE TELECOMMUNICATIONS ACT

THE TELECOMMUNICATIONS ACT'S LOCAL COMPETITION FRAMEWORK

    One of the key goals of the Telecommunications Act is to encourage
competition in local telephone service. To do this, the Telecommunications Act
provides three means by which telecommunications service providers can enter the
local phone service marketplace. The three modes of entry are as follows:


    - RESALE.  Incumbent local telephone companies are required to permit new
      telecommunications service providers to purchase their services for resale
      to the public at a wholesale rate that is less than the rate charged by
      the incumbent local telephone companies to their retail customers.



    - ACCESS TO NETWORK ELEMENTS.  Incumbent local telephone companies are
      required to lease to new telecommunications service providers the various
      elements in their network that are used to provide local telephone
      service. The leased parts of the incumbent local telephone companies'
      networks are known as unbundled network elements. The incumbent local
      telephone companies must make unbundled network elements available at
      rates that are based on their forward-looking economic costs.



    - CONSTRUCTION OF NEW FACILITIES.  New telecommunications service providers
      may also enter the local phone service market by building entirely new
      facilities. The incumbent local telephone companies are required to allow
      new telecommunications service providers to interconnect their facilities
      with the incumbent's, so each carrier's customers can reach the other's.



    To facilitate new telecommunications service providers' entry into local
telephone markets using one or more or some combination of these three methods,
the Telecommunications Act imposes on incumbent local telephone companies the
obligation to open their networks and markets to competition. When requested by
competitors, incumbent local telephone companies are required to negotiate, in
good faith, agreements that lay out terms governing the interconnection of their
network, access to unbundled network elements and resale. Incumbent local
telephone companies must also allow competing carriers to "collocate," or place
their own equipment in incumbents' central offices.


    In addition, all local exchange carriers, including both incumbent and new
telecommunications service providers, are subject to the following requirements:

    - INTERCONNECTION.  All local telecommunications service providers must
      permit their competitors to interconnect with their facilities either
      directly or indirectly. Incumbent telephone companies are additionally
      obligated to permit interconnection at any technically feasible point
      within their networks, on nondiscriminatory terms, at prices based on cost
      (which may include a reasonable profit);

    - NUMBER PORTABILITY.  All local telecommunications service providers must
      implement number portability technology that allows a customer to retain
      its existing phone number if it switches from one local exchange carrier
      to a competitor. This technology primarily benefits new telecommunications
      service providers, which can gather market share more easily if customers
      can switch to these carriers without changing telephone numbers;


    - RECIPROCAL COMPENSATION.  All local telecommunications service providers
      must complete local calls originated by other telecommunications service
      providers under reciprocal compensation arrangements. That is, the local
      provider terminating a local call is entitled to payment from the local
      provider originating a call. Charges assessed by the incumbent telephone
      company for terminating calls originated on a new telecommunications
      service provider's network must be based on a reasonable approximation of
      additional cost. The FCC recently determined that Internet service
      provider-bound traffic is interstate in nature, not local, and is
      therefore outside the scope of the Telecommunications Act's reciprocal
      compensation provisions. The FCC has initiated a proceeding to determine
      appropriate carrier-to-carrier compensation for Internet service
      provider-bound traffic. At the same time, the FCC declined to overturn a
      multitude of


                                       45
<PAGE>

      state decisions requiring incumbent telephone companies to pay new
      telecommunications service providers compensation for delivering Internet
      traffic to Internet service providers that had selected a new
      telecommunications service provider as their local service provider. The
      United States Court of Appeals for the District of Columbia Circuit
      recently vacated the FCC's decision, and remanded the case to the FCC for
      further consideration of the jurisdictional nature of Internet service
      provider-bound traffic. The FCC has not yet acted on this remand. In
      addition, legislation recently was introduced in Congress that would
      eliminate the payment of reciprocal compensation for Internet service
      provider-bound calls.


    - DIALING PARITY.  Requires all local telecommunications service providers
      to provide nondiscriminatory access to telephone numbers, operator
      services, directory assistance and directory listing with no unreasonable
      dialing delays. Local dialing parity ensures that customers on one local
      exchange carrier do not have to dial extra digits to reach customers on a
      different local or toll carrier's network; and


    - ACCESS TO RIGHTS-OF-WAY.  Requires all local telecommunications service
      providers to permit competing providers access to poles, ducts, conduits
      and rights-of-way at reasonable and nondiscriminatory rates, terms and
      conditions. The FCC has opened a proceeding seeking to define in greater
      detail the scope of the incumbent local telephone company's obligation to
      provide access to rights-of-way that it owns or controls, including those
      within its own central offices and other buildings, and buildings owned by
      private third parties. The United States Court of Appeals for the Eleventh
      Circuit recently held that utilities, including local telecommunications
      providers, are not required to provide access to their poles, ducts,
      conduits, and rights-of-way, for use by companies that employ wireless
      telecommunications technology, or seek access to provide Internet
      services. The FCC has sought reconsideration of this decision.



    Executing an interconnection agreement does not guarantee a new
telecommunications service provider unfettered access to the incumbent local
telephone company's market. Interconnection agreements between incumbent local
telephone companies and new telecommunications service providers may have short
terms, requiring the new telecommunications service provider to renegotiate the
agreements on a regular basis. Incumbent local telephone companies may not
provide timely provisioning or adequate service quality, thereby impairing a new
telecommunications service provider's reputation with customers who can easily
switch back to the incumbent local telephone company. In addition, the prices
set in the agreements or through state regulatory commission arbitration
proceedings may be subject to changes mandated by state regulatory commissions
as they develop permanent rules governing interconnection and may not in all
instances be set at levels that allow new telecommunications service providers
to compete effectively.


THE FCC'S RULES IMPLEMENTING THE TELECOMMUNICATIONS ACT'S LOCAL COMPETITION
  PROVISIONS

    In August 1996, the FCC issued an order implementing the local competition
provisions of the Telecommunications Act. The FCC established rules about how
interconnection and collocation were to be provided, put forth a method that
state commissions should use to establish prices for interconnection and
unbundled network elements, and specified which parts of an incumbent's network
must be made available as unbundled network elements to competing carriers. The
FCC also held that incumbent telephone companies must provide new
telecommunications service providers with "combinations" of unbundled network
elements, making it possible for new telecommunications service providers, in
many instances, to provide service to customers by leasing all of the component
unbundled network elements from the incumbent telephone company. This method of
providing service is known as the unbundled network element platform, or UNE-P.
Specifically, among other rules, the FCC established a list of seven network
elements, comprising most of the significant facilities, features,
functionalities or capabilities of the network, that the incumbent telephone
companies must unbundle. In addition, the FCC mandated a particular
forward-looking pricing methodology for these network elements that produces
relatively low element prices that are favorable to competitors.

                                       46
<PAGE>
    After the FCC released its rules, numerous parties challenged the rules
before the United States Court of Appeals for the Eighth Circuit. The Eighth
Circuit overturned many of the FCC's rules on the grounds that the agency had
exceeded its authority and misinterpreted the law.

    On January 25, 1999, the United States Supreme Court largely reversed the
Eighth Circuit's decision, holding that the FCC has general jurisdiction to
implement the local competition provisions of the Telecommunications Act and
reestablishing the validity of many of the FCC's interconnection rules. In so
doing, the Supreme Court stated that the FCC has authority to set pricing
guidelines for unbundled network elements, to prevent incumbent telephone
companies from separating existing combinations of network elements, and to
establish "pick and choose" rules regarding interconnection agreements. "Pick
and choose" rules would permit a carrier seeking interconnection to pick and
choose among the terms of service from other interconnection agreements between
the incumbent and various new telecommunications service providers.


    Although it upheld the FCC's jurisdiction to establish unbundled network
element pricing guidelines, the Supreme Court did not evaluate the specific
"forward-looking" pricing methodology adopted by the FCC, and the case has been
remanded to the Eighth Circuit for further consideration of that specific
pricing methodology. Some incumbent telephone companies have argued that this
pricing methodology does not allow adequate compensation for the provision of
unbundled network elements. The Eighth Circuit heard oral arguments on this
pricing issue on September 16, 1999, but has not yet issued a ruling. We cannot
predict the outcome of this proceeding. If the Eighth Circuit fails to uphold
the FCC's forward-looking pricing methodology, it may materially adversely
affect our business. In addition to the Eighth Circuit, the Supreme Court
recently agreed to hear argument on the merits of the FCC's forward looking
pricing methodology in the separate context of the FCC's new universal service
support program. See Additional Federal Issues--Universal Service, below.


    Additionally, the Supreme Court vacated the FCC rules defining what network
elements must be unbundled and made available to the new telecommunications
service providers by the incumbents. The Supreme Court held that the FCC must
provide a stronger rationale to support the degree of unbundling ordered.

    On November 5, 1999, in response to the Supreme Court's ruling, the FCC
released new rules specifying which portions of the incumbent telephone
companies' networks must be made available as unbundled network elements. The
FCC reaffirmed that incumbent telephone companies must provide unbundled access
to the following six network elements:

    - loops, including loops used to provide high-capacity and advanced
      telecommunications services such as digital subscriber lines;

    - network interface devices;

    - local circuit switching;

    - dedicated and shared transport;

    - signaling and call-related databases; and

    - operations support systems.


    The FCC removed from the list of unbundled network elements operator service
and directory assistance. The FCC concluded that the market has developed
sufficiently that new telecommunications service providers can and do
self-provide these services, or acquire them from alternative sources. The FCC
also noted that incumbent telephone companies remain obligated under the
non-discrimination requirements of the Communications Act of 1934 to comply with
the reasonable request of a new telecommunications service provider that
purchases these services from the incumbent telephone companies to rebrand or
unbrand those services, and to provide directory assistance listings and updates
in daily electronic batch files. In addition, the competitive checklist
contained in Section 271 of the Communications Act of 1934 requires Bell
operating companies to provide nondiscriminatory


                                       47
<PAGE>

access to these services as a precondition to obtaining authority to offer long
distance services within their service territory.


    The FCC also modified the local switching unbundled network element,
concluding that incumbents need not provide access to unbundled local circuit
switching for customers with four or more lines that are located in the densest
parts of the top 50 metropolitan statistical areas so long as the incumbent
makes available an alternative arrangement for reaching customers, known as the
enhanced extended link. The enhanced extended link allows new telecommunications
service providers to gain access to customers without collocating in every
central office, because it combines the local loop with a multiplexer and
transport to the new telecommunications service provider's local existing
collocated facilities or switch. Notwithstanding the FCC's ruling, unrestricted
access to unbundled switching is available in Texas, where state rulings require
incumbent telephone companies to make switching available as an unbundled
network element.

    In addition to these changes, the FCC also:

    - Limited the scope of the shared transport unbundled network element,
      holding that the incumbent must only offer shared transport as a unbundled
      network element where unbundled local circuit switching is provided.

    - Held that incumbents are not required to offer packet switching as a
      unbundled network element in most cases.

    - Held that both the loop and transport unbundled network elements include
      access to "dark fiber." Dark fiber is distinguished from "lit fiber"
      transmission capacity in that dark fiber is sold independently from the
      electronics necessary to "light" the fiber and transmit information. The
      availability of dark fiber from incumbents as a unbundled network element
      could create an additional source of dark fiber in the market.

    - Ordered "sub-loop unbundling," which will allow new telecommunications
      service providers to connect at any feasible point along the local loop,
      and not just at the central office. In some incumbent networks, subloop
      unbundling will make it easier for new telecommunications service
      providers to use portions of the unbundled network element loop to offer
      advanced services, such as digital subscriber lines. In a separate order,
      the FCC also ordered the unbundling of the "high-frequency" portion of the
      loop, which also makes it easier and less expensive for new
      telecommunications service providers to use unbundled network elements to
      offer advanced services, such as digital subscriber lines.

    The FCC's decision regarding unbundled network elements is currently the
subject of petitions for reconsideration filed at the FCC by various parties,
including us. Some incumbent telephone companies have asked the FCC to expand
the limitation on switching by, among other things, extending its geographic
scope. We and other new telecommunications service providers have asked the FCC
to either do away with the limitation or make it applicable to only larger
customers. We cannot predict the outcome of this proceeding. If the FCC further
restricts the availability of unbundled switching, it could adversely affect our
ability to serve customers efficiently.

    Another open question is whether incumbent telephone companies are required
to combine network elements not currently combined in their networks for
requesting new telecommunications service providers. The FCC's rules requiring
the incumbent telephone companies to do so were vacated by the Eighth Circuit,
but the FCC and the new telecommunications service provider industry have asked
that court to reinstate the rules in the wake of the Supreme Court's decision.
If the rules are reinstated, it will significantly expand the ability of new
telecommunications service providers to provide service to customers using
network elements purchased from the incumbent telephone companies. Also
unsettled is the scope of the FCC's rule requiring incumbent telephone companies
to provide requesting new telecommunications service providers with combinations
of network elements that are "currently combined" in the incumbent telephone
company's network. The new telecommunications

                                       48
<PAGE>
service provider industry has taken a broad view of this requirement,
interpreting it to mean that new telecommunications service providers are
entitled to purchase network element combinations so long as they are combined
anywhere in the incumbent telephone company's network. The incumbent telephone
companies, by contrast, have taken a much narrower view, arguing that the rule
requires the incumbent telephone companies only to provide combinations of
network elements that are currently in service to a particular customer. The
ultimate resolution of this question could expand or restrict our ability to
provide service to our customers using network elements purchased from the
incumbent telephone company.

    The Eighth Circuit is expected to rule on the pricing issue in the next
several months and may also rule on the incumbent telephone companies'
obligation to provide new network element combinations in the same decision. It
is not clear when the FCC or the courts will act to define the scope of
"currently combined." The possible impact of the resolution of these open issues
on existing interconnection agreements between incumbent telephone companies and
new telecommunications service providers or on agreements that may be negotiated
in the future cannot be determined at this time.


    In addition to its rulings regarding interconnection and unbundled network
elements, the FCC has issued a series of orders on the ability of new
telecommunications service providers to provide digital subscriber lines and
other high-bandwidth services to their customers for, among other things,
Internet access. Those orders have made clear that incumbent local telephone
companies must, where technically feasible, provide new telecommunications
service providers with high-quality loops capable of supporting digital
subscriber lines and that the incumbent telephone companies must provide new
telecommunications service providers with information concerning the make-up of
their networks to allow the new telecommunications service provider to determine
if a particular customer can be served with digital subscriber line service.
However, many of the details of the orders' implementation are unsettled and we
cannot assure you that the rules are sufficient to ensure that the incumbent
telephone companies meet their obligations. In addition, the Telecommunications
Act and FCC rules permit us to "collocate" within incumbent local telephone
company central offices. In March 2000, in response to an appeal of these rules,
the United States Court of Appeals for the District of Columbia Circuit held
that the Telecommunications Act requires the incumbent to permit collocation of
only that equipment that is essential to permit interconnection with the
incumbent's local telephone network. The D.C. Circuit remanded the matter to the
FCC for further consideration. The D.C. Circuit's interpretation could
potentially limit our right to collocate equipment used to provide Internet
services, including packet switches, at incumbent local telephone company
central offices, raising our costs. The FCC has not yet taken any further
action, but GTE and all of the Bell operating companies have agreed to take
steps to minimize the disruption to collocation arrangements while the FCC
considers these issues on remand.


THE STATES' ROLE IN IMPLEMENTING THE LOCAL COMPETITION PROVISIONS

    Although the FCC establishes nationwide guidelines governing entry by new
telecommunications service providers under the Telecommunications Act, state
regulatory commissions also have major roles in implementing the local
competition provisions of the act. Among other things, state regulatory
commissions must approve or reject interconnection agreements, and they have
chief responsibility for arbitrating and mediating these agreements if the
negotiating carriers cannot reach an understanding on the agreement's terms.
State regulatory commissions are also charged with developing and implementing
cost-based prices for interconnection and unbundled network elements, in
accordance with the Telecommunications Act and the forward-looking pricing
guidelines set by the FCC. State regulatory commissions are also permitted to
establish additional unbundled network elements consistent with federal law and
policy.

                                       49
<PAGE>
BELL OPERATING COMPANIES ENTRY INTO LONG DISTANCE


    The Telecommunications Act also seeks to encourage local competition by
requiring the regional Bell operating companies to demonstrate on a
state-by-state basis that they have adequately opened their network and market
to competitors before they can provide long distance service to end users in
their own local service areas. Specifically, the Telecommunications Act lays out
a 14-point checklist which generally requires a regional Bell operating company
to prove to the FCC that it has complied with the interconnection and network
access obligations discussed above and that it faces effective competition in
the state where it seeks to provide long distance service. While the FCC has
ultimate responsibility for deciding whether the checklist conditions have been
met, the FCC is required first to consult with the appropriate state regulatory
commission.



    Southwestern Bell has also applied for authority to provide long distance
service in Texas and, on June 13, 2000, the United States Department of Justice
(DOJ) filed comments at the FCC supporting Southwestern Bell's Texas application
and indicating its opinion that Southwestern Bell's Texas local exchange markets
are open to competition. The FCC must give substantial weight to the DOJ's
evaluation, but is not required to reach the same conclusion, or to grant the
application based on the DOJ's support. The FCC is expected to rule on
Southwestern Bell's application in July, 2000. The FCC is expected to rule on
Southwestern Bell's application in July, 2000. Southwestern Bell has also begun
the process of applying for long distance authority in Kansas by making a
preliminary filing with the Kansas state regulatory commission. If Southwestern
Bell receives approval from the FCC as described above, Southwestern Bell will
be able to provide in-region long distance services, which will enable it to
provide customers with a full range of local and long distance
telecommunications services. The ability of Southwestern Bell to provide long
distance services is expected to be an additional source of competition for us.


OTHER FEDERAL REGULATION

    The FCC regulates our interstate and international service offerings. Those
services include our provision of interstate and international long distance
service and our provision of interstate access service. The FCC has established
different levels of regulation for dominant carriers and non-dominant carriers.
Incumbent telephone companies, such as the Bell operating companies and GTE, are
currently considered dominant carriers, and are subject to extensive rate and
operational regulation, while new telecommunications service providers such as
we are considered non-dominant carriers, and are subject to substantially less
regulation.

INTERSTATE AND INTERNATIONAL LONG DISTANCE SERVICES

    Interstate and international long distance services of non-dominant carriers
are subject to relatively little regulation by the FCC. Our provision of
international long distance services requires prior authorization by the FCC
under Section 214 of the Telecommunications Act, which we have obtained. We are
also required to file tariffs with the FCC for international long distance
service on an ongoing basis.

    Under the FCC's streamlined regulation of non-dominant carriers, we may
install and operate facilities for the transmission of domestic interstate
communications without prior FCC authorization.


    In addition, in October 1996, the FCC adopted an order in which it
eliminated the requirements that non-dominant interstate interexchange carriers
maintain tariffs on file with the FCC for domestic interstate services. The
order does not apply to the switched and special access services of the Bell
operating companies or other local exchange carriers. The FCC order was issued
under authority granted to the FCC in the 1996 Act to "forbear" from regulating
any telecommunications services provider under some circumstances. After a
nine-month transition period, relationships between interstate carriers and
their customers would be set by contract. At that point, long distance companies
would be prohibited from filing tariffs with the FCC for interstate, domestic,
interexchange services.


                                       50
<PAGE>

Several parties filed notices for reconsideration of the FCC order and other
parties appealed the decision. On February 13, 1997, the D.C. Circuit stayed the
effectiveness of the FCC's order, pending its review of the order on the merits.
After a lengthy appeal, on April 28, 2000, the D.C. Circuit affirmed the FCC's
decision to require mandatory detariffing of domestic interstate long distance
services.



    On May 9, 2000, the FCC issued a Public Notice establishing a nine-month
transition period, beginning on May 1, 2000, and ending January 31, 2001, during
which all interstate interexchange carrier tariffs will be cancelled. During
this transition, non-dominant interexchange carriers can no longer file new
contract tariffs or other long-term service arrangements with the FCC as a means
of providing notice to their customers of prices, terms, and conditions on which
they offer their interstate services.



    The FCC has required that non-dominant interexchange carriers post their
rates, terms and conditions for all their interstate, domestic services on their
Internet web sites if they have one; this rule is effective once these services
are detariffed. Detariffing may result in significant administrative expenses
for us. The obligation to provide non-discriminatory, just and reasonable prices
remains unchanged under the Communications Act of 1934. Tariffs also allow a
carrier to limit its liability to its customers, including in connection with
service interruptions. Without tariffs, we may become liable for costs that we
would have been able to limit through tariff filings, and we cannot assure you
that the potential liabilities will not have a material adverse effect on our
results of operations and financial condition.


ACCESS SERVICES

    Unlike dominant carriers, which are subject to extensive rate regulation, we
and other non-dominant carriers are subject to relatively little regulation of
our interstate access services. The FCC has eliminated the requirement that
non-dominant carriers must file tariffs for their access services. While no
longer mandatory, carriers may continue to file access tariffs. We have chosen
to continue to do so.


    In August 1999, the FCC granted incumbent local telephone companies subject
to price cap rate regulation, including the regional Bell operating companies,
substantial pricing flexibility with regard to some interstate access services.
Among other things, the FCC's new rules permit incumbent telephone companies,
upon a showing that the services in question are subject to sufficient levels of
competition, to offer volume and term discounts and contract tariffs for
particular access services. The new rules also allow incumbent telephone
companies, upon meeting a higher competitive standard, to file tariffs for their
access services free from many rate structure requirements. To the extent these
regulatory initiatives enable or require incumbent local telephone companies to
offer selectively reduced rates for some access services, the rates we may
charge for these access services will likely be constrained. In addition, the
FCC has recently initiated a proceeding to examine whether to regulate the rates
that new telecommunications service providers charge for their access services.
While the FCC has received considerable opposition from the new
telecommunications service provider industry and others to doing so, we cannot
assure you that the FCC will not adopt some form of regulation for new
telecommunications service provider access charges. The timing of the FCC's
decision is uncertain.



    In addition to the pricing flexibility described above, the FCC recently
adopted a joint proposal from AT&T, Bell Atlantic, BellSouth, GTE, SBC
Communications and Sprint to lower significantly and deaverage interstate access
charges for price cap local exchange carriers. These pricing reforms could
increase competition among carriers offering local exchange and exchange access
service in our operating area.

ADDITIONAL FEDERAL ISSUES


    ACCESS TO POLES, DUCTS, CONDUITS AND RIGHTS-OF-WAY.  An area of the law that
remains in flux concerns the extent of a carrier's obligations to provide access
to poles, ducts, conduits and rights-of-way. We are obligated under Section 224
of the Communications Act to permit other carriers reasonable access to our
poles, ducts, conduits and rights-of-way and the FCC has adopted comprehensive
rules governing how access is to be provided. The Eleventh Circuit Court of
Appeals recently held that these rules do not obligate us to provide access to
carriers using wireless telecommunications technology or to those seeking access
in order to provide Internet services. The FCC is also currently considering
additional rules, including whether access to rooftops and space inside
buildings, including buildings owned by utilities, should be mandated under the
Telecommunications Act.


    EEO REPORT.  The FCC requires us to file an annual employment report to
comply with the FCC's equal employment opportunity policies.

    TRUTH IN BILLING.  The FCC has adopted new rules designed to make it easier
for customers to understand the bills of telecommunications carriers. These new
rules establish requirements regarding the formatting of bills and the
information that must be included on bills. These rules have been appealed in
federal court.

    ANTI-SLAMMING RULES.  The FCC implemented the so-called "anti-slamming"
rules, which protect consumers whose pre-subscribed carriers have been switched
without their consent. Under the rules, a carrier found to have slammed a
customer is subject to substantial fines and must remove from the consumer's
bill all charges incurred within 30 days of the slamming. While we do not engage
in these practices, a slamming fine, if levied, could have a material impact on
our business in the future.

    CUSTOMER PROPRIETARY NETWORK INFORMATION.  In February 1998, the FCC adopted
rules implementing Section 222 of the Communications Act of 1934, which governs
the use of customer proprietary network information by telecommunications
carriers. Customer proprietary network information generally includes any
information regarding a subscriber's use of a telecommunications service, where
it is obtained by a carrier solely by virtue of the carrier-customer
relationship. The FCC has clarified that customer proprietary network
information does not include a subscriber's name, telephone number, and address,
as this information is generally not derived from the carrier's provision of a
telecommunications service to a customer. Under the FCC's rules, a carrier may
only use a customer's proprietary network information to market services that
are "necessary to, or used in," the provision of a service that the carrier
already provides to the customer, unless it receives the customer's prior oral
or written consent to use that information to market other services. In
December 1999, the United States Court of Appeals for the Tenth Circuit vacated
the FCC's original and modified customer proprietary network information rules
on the grounds that they violate the First Amendment. However, Section 222 of
the Communications Act remains the law and that section, in addition to the
FCC's now-vacated rules, provides some guidance on the use of customer
proprietary network information rules. Uncertainty regarding restrictions on the
use of customer proprietary network information rules may impede our ability to
market integrated packages of services effectively and to expand existing
customers' use of our services.

    UNIVERSAL SERVICE.  On May 8, 1997, the FCC released an order establishing a
significantly expanded federal universal service subsidy regime under the
Telecommunications Act. The universal service program provides support to
carriers serving low-income customers and customers who live in areas where the
cost of providing telecommunications services is high. In addition, the FCC
established new subsidies for telecommunications and some information services
provided to qualifying schools and libraries and for services provided to rural
health care providers. Providers of interstate telecommunications services, as
well as other entities, such as private carriers offering excess capacity to end
user customers, must pay for these programs. Our contribution to the federal
support funds would be calculated based on a percentage of our gross end-user
interstate and international

                                       52
<PAGE>
telecommunications revenues. The assessment rate for the second quarter of 2000
is 5.7101% of interstate and international end-user telecommunications revenues.
The contribution factor issued by the FCC varies quarterly. The amounts
contributed may be billed to customers. Currently, the FCC is calculating
assessments based on the prior year's revenues. Assuming that the FCC continues
to calculate contributions based on the prior year's revenues, we believe that
we will not be liable to contribute any material amount to these programs during
2000 because we had limited interstate and international end user revenues in
1999. The threshold before we are required to contribute is a $10,000
contribution, which translates into roughly $175,000 in interstate end user
telecommunications revenues. With respect to subsequent years, however, we are
currently unable to quantify the amount of any contributions that we will be
required to make or the effect that these required contributions will have on
our financial condition.


    The FCC has recently adopted the cost model which it will use to determine
the support needed in high-cost areas and the inputs for the model. The new
high-cost support mechanism, which went into effect on January 1, 2000 for
non-rural carriers, substantially increases the amount of high-cost support
provided to non-rural carriers. The United States Court of Appeals for the Fifth
Circuit recently issued an order upholding in part, and reversing in part, the
May 8(th) FCC order implementing these funds. The Supreme Court recently agreed
to decide the constitutionality of the FCC's "forward looking" pricing
methodology used to compute universal service support payments to local exchange
carriers, and will hear argument on this issue during the 2000-2001 term. In
addition, numerous FCC orders revising these funds are subject to petitions for
reconsideration and further petitions for appeal. The outcome of these
proceedings or their effect cannot be predicted.



    In addition to the universal service mechanisms described above, the FCC
recently adopted a joint proposal from Bell Atlantic, BellSouth, GTE, SBC
Communications, AT&T, and Sprint to create a $650 million fund to provide
universal service support for interstate access charges. This fund could
significantly increase the contribution obligations of other telecommunications
carriers.


    COMMUNICATIONS ASSISTANCE FOR LAW ENFORCEMENT ACT.  Under this act,
telecommunications carriers are required to: (1) provide law enforcement
officials with call content and call identifying information under a valid
electronic surveillance warrant, and (2) reserve a sufficient number of circuits
for use by law enforcement officials in executing court authorized electronic
surveillance. If we provide facilities-based services, we may incur costs in
meeting both of these requirements. In particular, regarding the requirements
related to call content and identification, except in very limited circumstances
the government is required to compensate carriers only for the costs of making
equipment installed or deployed before January 1, 1995 compliant with this act.
While the telecommunications industry is attempting to negotiate legislative and
administrative changes to this reimbursement cut-off date, as it stands today,
we will be financially responsible for ensuring that our post-1995 equipment is
in compliance. Regarding the circuit capacity requirements, the government will
finance any necessary increases in capacity for equipment that we have
specifically identified as installed or deployed prior to September 8, 1998, and
we are responsible for paying only for any necessary increases in capacity for
equipment installed or deployed after that date.

STATE AND LOCAL REGULATION

    In general, state regulatory commissions have regulatory jurisdiction over
us when our facilities and services are used to provide local and other
intrastate services. Under the Telecommunications Act, state commissions
continue to set the requirements for providers of local and intrastate services,
including quality of services criteria. State regulatory commissions also can
regulate the rates charged by new telecommunications service providers for
intrastate and local services and can set prices for interconnection by new
telecommunications service providers with the incumbent telephone company
networks, in accordance with guidelines set by the FCC. In addition, state
regulatory commissions in many instances have authority under state law to adopt
additional regulations governing local competition, so long as the state's
actions are not inconsistent with federal law or regulation.

                                       53

    Most state regulatory commissions require companies that wish to provide
intrastate common carrier services to register or be certified to provide these
services. These certifications generally require a showing that the carrier has
adequate financial, managerial and technical resources to offer the proposed
services in a manner consistent with the public interest. In most states, we are
also required to file tariffs setting forth the terms, conditions and prices for
services that are classified as intrastate, and to update or amend our tariffs
as rates change or new products are added. We may also be subject to various
reporting and record-keeping requirements.

    We are currently certified by the Missouri Public Service Commission, the
Kansas Corporation Commission, the Texas Public Utilities Commission and the
Oklahoma Corporation Commission to provide both local and intrastate long
distance service in those states. We have tariffs on file in each of these
states.

    If we choose to install our own transmission facilities, we may be required,
in some cities, to obtain street opening and construction permits, permission to
use rights-of-way, zoning variances and other approvals from municipal
authorities. We also may be required to obtain a franchise to place facilities
in public rights of way. In some areas, we may be required to pay license or
franchise fees for these approvals. We cannot assure you that fees will remain
at current levels, or that our competitors will face the same expenses, although
the Telecommunications Act requires that any fees charged by municipalities be
reasonable and non-discriminatory as among telecommunications carriers.

BOARD COMPOSITION

    The number of directors is set at 11. In accordance with the terms of our
certificate of incorporation, as amended and restated prior to the closing of
this offering, the terms of the office of the board of directors will be divided
into three classes, with each class holding office for staggered three year
terms:

    - Class I directors' terms will expire at the annual meeting of stockholders
      to be held in 2001;

    - Class II directors' term will expire at the annual meeting of stockholders
      to be held in 2002; and

    - Class III directors' term will expire at the annual meeting of
      stockholders to be held in 2003.

    The Class I directors will be Messrs. Clammer, Ejabat and Palmer. The
Class II directors will be Messrs. Bradley, Kravis and Roberts. The Class III
directors will be Messrs. Greene, Jalkut, Navab and Scott. Currently, there is
one vacancy on the board. When this vacancy is filled, we intend for the new
director to be a Class I director. At each annual meeting of stockholders after
the initial classification of the board of directors, the successors to
directors whose term will then expire will be elected to serve from the time of
election and qualification until the third annual meeting following election.
Any additional directorships resulting from an increase in the number of
directors will be distributed among the three classes so that, as nearly
possible, each class will consist of one-third of the directors. This
classification of the board of directors may have the effect of delaying or
preventing changes in our control or management. Directors may be removed for
cause by the affirmative vote of the holders of a majority of the common stock.

(1) Includes options to purchase shares of our common stock, which were issued
    under our 1998 employee stock option plan. Prior to the private placement of
    our series B preferred stock, we were a party to various stock option
    agreements with our employees, all of which were governed by our 1997 stock
    option plan. In connection with the 1998 private placement of series B
    preferred stock, the 1997 stock option plan was replaced with the 1998 stock
    option plan, and all stock option agreements governed by the 1997 stock
    option plan were terminated. Options issued to the members of management
    during 1998 were granted under our 1998 employee stock option plan and were
    exercisable immediately on grant at an exercise price of $0.001 per share.
    The shares issued under these options vest over a four-year period, at a
    rate of 6.25% per quarter. Options issued during 1999 were also granted
    under our 1998 stock option plan and vest 25% at the first anniversary of
    the grant, then 6.25% per quarter thereafter. All stock options have been
    adjusted to reflect a stock dividend made on June 23, 1998. Holders of
    exercised options have voting power with respect to all shares of common
    stock underlying the options. Upon termination of employment, we have the

------------------------

(1) Options granted to purchase shares of our common stock were made under our
    1998 employee stock option plan. In the event that a purchaser ceases to
    provide service to us and our affiliates, we have the right to repurchase
    any of that person's unvested shares of common stock at the original option
    exercise price. Generally, these options vest 25% on the first anniversary
    of the grant date and quarterly thereafter at a rate of 6.25%.

(2) The percentage of total options was calculated based on options to purchase
    an aggregate of 3,221,666 shares of common stock granted to employees under
    the 1998 stock option plan in 1999.

(3) The potential realizable value was calculated based on the ten-year term of
    the options and assumed rates of stock appreciation of 5% and 10%,
    compounded annually from the date the options were granted to their
    expiration date based on the fair market value of the common stock on the
    date of grant.

1998 EMPLOYEE STOCK OPTION PLAN

    Under our 1998 employee stock option plan, as amended, options to purchase
shares of our common stock in the form of both incentive stock options and
nonqualified stock options were granted to our employees or employees of certain
of our subsidiaries. A total of 13,858,916 shares of our common stock were
reserved for issuance under this option plan. As of December 31, 1999, options
to acquire 3,645,375 shares were issued and outstanding with a weighted average
exercise price of $2.00 per share. These options generally vest 25% per year
over four years from the date of grant. Under a resolution of our board of
directors, no new options may be granted under this option plan.

2000 EQUITY PARTICIPATION PLAN

    On March 30, 2000, we adopted the 2000 Equity Participation Plan, which we
also refer to as the Equity Plan. The principal purpose of the Equity Plan is to
attract, retain and motivate select officers, employees, consultants and
directors through the granting of stock-based compensation awards. The Equity
Plan will provide for a variety of these awards, including non-qualified stock
options, incentive stock options (within the meaning of Section 422 of the
Internal Revenue Code), stock appreciation rights, restricted stock, deferred
stock, dividend equivalents, performance awards, stock payments, and other
stock-related benefits. A total of 10,770,000 shares of common stock are
reserved for issuance

                                       61
<PAGE>
under the Equity Plan. The maximum number of shares that may be subject to
awards granted under the Equity Plan to any individual in any calendar year
cannot exceed 1,795,000.


    We expect to grant approximately 1,700,000 options exercisable at the
offering price under the Equity Plan on the closing date of the offering.


    The Equity Plan will provide that the committee has the authority to select
the employees and consultants to whom awards are to be made, to determine the
number of shares to be subject to the Equity Plan and the terms and conditions
of the awards and the Equity Plan, and to make all other determinations and to
take all other actions necessary or advisable for the administration of the
Equity Plan for employees or consultants.

    The Equity Plan also provides that at specified times our non-employee
directors will automatically be granted options to purchase shares of our common
stock. All options granted to our non-employee directors will have an exercise
price per share equal to the fair market value per share of our common stock as
of the date of grant and all of these options will become exercisable in equal
annual installments of 25% on each of the first four anniversaries of the date
of grant. Each individual who is a non-employee director at the time of the
offering will be granted an option to purchase 17,950 shares of our common stock
at the time of the offering. After the offering, each non-employee director who
becomes a member of the board will initially receive an option to purchase
17,950 shares of our common stock upon becoming a member. In addition, all
non-employee directors will be granted an option to purchase an additional 8,975
shares of our common stock at each annual meeting of our stockholders after the
offering at which he or she is reelected to our board of directors.

    Each of the committee and the board will be authorized to adopt, amend and
rescind rules relating to the administration of the Equity Plan, and to amend,
suspend and terminate the Equity Plan. We have attempted to structure the Equity
Plan in a manner such that remuneration attributable to stock options and other
awards will not be subject to the deduction limitation contained in
Section 162(m) of the Internal Revenue Code.

2000 EMPLOYEE STOCK PURCHASE PLAN

    On April 13, 2000, we adopted the 2000 Employee Stock Purchase Plan, as
amended, or the Purchase Plan. The Purchase Plan is intended to be an "employee
stock purchase plan" as described in Section 423 of the Code. The Purchase Plan
will be administered by the compensation committee of our board of directors.
Subject to the "evergreen" provision described below, a total of 1,795,000
shares of our common stock are reserved and available for purchase under the
Purchase Plan, plus an annual increase on the first day of each of our fiscal
years beginning in 2001 and ending in 2010, equal to the lesser of
(a) 1,795,000 shares, (b) 1.2% of the shares outstanding on the last day of the
immediately preceding fiscal year or (c) number of shares as is determined by
the board.

    The Purchase Plan will permit eligible employee participants to purchase our
common stock through payroll deductions at a price per share which is equal to
the lesser of 85% of the fair market value of the common stock on the first or
the last day of an offering period. The Purchase Plan will provide for two
offering periods beginning each calendar year. The first is April 15 through
April 14 of the following year, and the second is October 15 through October 14
of the following year, except that the first offering period under the Purchase
Plan will begin on the closing of the offering and will end on April 14, 2001.
On the last day of each offering period, each participant's accrued payroll
deductions will be automatically applied to the purchase of common stock.

    Employees eligible to participate in the Purchase Plan consist of all
persons employed by us or by the subsidiaries described in the Purchase Plan,
except that the Purchase Plan will exclude from participation any employee whose
customary employment is for less than 20 hours per week or who is employed for
less than five months during a calendar year and any employee who owns stock

                                       62
<PAGE>
representing 5% or more of the total combined voting power or value of all
classes of our stock or the stock of our subsidiaries. No participant will be
permitted to purchase shares of common stock in any calendar year under the
Purchase Plan with an aggregate fair market value (generally determined as of
the beginning of the plan year) in excess of $25,000.

401(K) PLAN

    We have adopted a tax-qualified employee savings and retirement plan, or
401(k) plan, covering all of our full-time employees. Under the 401(k) plan,
employees may elect to reduce their current compensation up to the statutorily
prescribed annual limit and have the amount of the reduction contributed to the
401(k) plan. The 401(k) plan is intended to qualify under Section 401 of the
Code so that contributions by employees to the 401(k) plan and income earned on
plan contributions are not taxable to employees until withdrawn from the 401(k)
plan. The trustees under the 401(k) plan, at the direction of each participant,
invest the participant's assets in the 401(k) plan in selected investment
options.

1999 OPTION VALUES

    The following table shows for the fiscal year ended December 31, 1999,
information regarding options granted to, exercised by, and held at year end by,
our chief executive officer and each of our four other most highly paid

(1) For purposes of this table alone, "exercise" means an employee's acquisition
    of shares of common stock which have already vested, "exercisable" means
    options to purchase shares of common stock which are subject to exercise and
    "unexercisable" means all other options to purchase shares of common stock.


(2) Amounts shown under the "Value Realized" and "Value of Unexercised
    In-the-Money Options" are based upon an assumed initial public offering
    price of $     per share minus the per share exercise price multiplied by
    the number of shares underlying the option.


(3) Includes options to purchase shares of common stock, which were issued under
    the 1998 employee stock option plan. Options issued during 1998 under the
    1998 employee stock option plan were granted at an exercise price of $0.001
    per share. Options issued during 1999 under the 1998 stock option plan were
    granted at an exercise price of $2.51 per share other than 50,000 options
    that were granted in 1999 to Mr. Goldman at an exercise price of $1.67 per
    share. All options vest 25% on the first anniversary of the grant date and
    quarterly thereafter at a rate of 6.25% other than 50,000 options that were

EMPLOYMENT AGREEMENTS

    Each of Messrs. Scott, Goldman, Lawhon, Moline, Shackelford and Vranicar
entered into an amended and restated employment agreement with us in October
1999. In addition, Mr. Sauder entered into an employment agreement with us in
February 1998, and Mr. Hollingsworth entered into an employment agreement with
us in February 2000.

    The base salary under each of these agreements is $200,000 per year, except
that Mr. Scott's base salary is $250,000 per year, Mr. Goldman's is $225,000 per
year and Mr. Sauder's is $213,000 per year. Each of the executives is eligible
for a bonus based on achievement of performance criteria established by the
board for that executive.

    Each of the employment agreements provides that upon termination of
employment by us, other than for cause, disability or death, or termination of
the employment by the executive for good reason, we will pay the executive the
following severance. We will pay the executive's salary for the remainder, if
any, of the calendar month in which the termination is effective and, in the
case of each of Messrs. Scott, Vranicar, Shackelford and Goldman, 24 calendar
months thereafter and, in the case of each of Messrs. Lawhon, Sauder,
Hollingsworth and Moline, 12 calendar months thereafter. In addition, we will
pay each executive his prorated targeted incentive compensation for the year
during which the termination is effective plus, in the case of each of
Messrs. Scott, Vranicar, Shackelford and Goldman, two times the executive's
targeted incentive compensation for that year, and, in the case of each of
Messrs. Lawhon, Hollingsworth and Moline, the full amount of the executive's
targeted incentive compensation for that year. Upon termination of employment
for disability, we will pay the employee's salary through the remainder of the
calendar month during which the termination is effective and for the lesser of
(1) six calendar months thereafter or (2) the period until disability insurance
benefits commence. Upon termination of employment from death, we will pay the
employee's salary through the end of the calendar month in which his death

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

SERIES D PREFERRED STOCK OFFERING

    In July 1999, we completed a private placement of 2,222,222 shares of
series D preferred stock at a purchase price of $4.50 per share for aggregate
proceeds of approximately $10.0 million. The transaction was consummated
pursuant to the purchasers rights agreement described below and the series D
preferred stock purchase agreement. Under the series D preferred stock purchase
agreement, NPG, a stockholder that owned in excess of 5% of our voting
securities at the time of the series D preferred stock offering, purchased
$1.0 million of series D preferred stock, and parties affiliated with NPG,
including Henry H. Bradley, chairman of our board of directors at that time and
of NPG, purchased $500,000 of series D preferred stock. Advantage Capital
Missouri Partners I, L.P., a stockholder that owned in excess of 5% of our

Mr. Palmer, one of our directors at the time of the series D preferred stock

SERIES F PREFERRED STOCK OFFERING


    In August 1999, we issued and sold 13,333,334 shares of our series F
preferred stock at a purchase price of $4.50 per share to BTI Ventures, L.L.C.,
an affiliate of KKR, for aggregate proceeds of $60.0 million. BTI received three
seats on our then seven-seat board of directors. Additionally, in March 2000,
BTI exercised its options to purchase 5,263,158 shares of series F preferred
stock at $4.75 per share and 5,000,000 shares of series F preferred stock at
$5.00 per share. These transactions were funded and the associated shares were
issued in April 2000. Giving effect to this exercise, BTI's investment would
have represented a 51.2% equity interest as of March 31, 2000. In connection
with their exercise of these options, BTI received two additional seats on our
eleven-seat board of directors.


    In connection with the series F preferred stock offering, we repurchased
2,222,222 shares of our series C preferred stock from Stephen L. Sauder, a
stockholder who owned more than 5% of our voting securities at the time of the
series F preferred stock offering, for $10.0 million.

    Also, in connection with the series F preferred stock offering, we converted
each outstanding share of our series B preferred stock into one share of amended
and restated series B preferred stock. In addition, the holders of series B
preferred stock surrendered their existing redemption and participating
liquidation preference in exchange for 0.2222 shares of our series E preferred
stock. We redeemed the series E preferred stock issued to the series B preferred
stock holders for a total of $8.6 million. The rights and preferences of the
series B preferred stock were amended and restated to remove mandatory
redemption rights and change the liquidation rights.

    In connection with the series F preferred stock offering, NPG, a stockholder
that owned in excess of 5% of our voting securities at the time of the series F
preferred stock offering, received 366,320 shares of series E preferred stock,
which were redeemed for an aggregate total of $1.6 million, and parties
affiliated with NPG, including Henry H. Bradley, chairman of our board of
directors at that time and of NPG, received 73,264 shares of series E preferred

stock, which were redeemed for an aggregate total of $85,718. KCEP I and KCEP
Ventures II together received an aggregate of 210,022 shares of series E
preferred stock, which were redeemed for an aggregate total of $945,099.

PURCHASERS RIGHTS AGREEMENT

    Our current stockholders are parties to the purchasers rights agreement,
which provides that they vote their respective shares in a manner as to elect
persons specified in the agreement to serve as directors. The holders of
series F preferred stock have agreed to vote their shares to elect
Messrs. Greene, Navab and Clammer. The two additional designees of the holders
of series F preferred stock are Messrs. Kravis and Roberts. In addition, the
holders of series B preferred stock, series C preferred stock and series D
preferred stock have agreed to vote their shares to elect Henry H. Bradley and
Thomas R. Palmer. The holders of common stock have agreed to vote their shares
for the election of David E. Scott. So long as the purchasers rights agreement
is in effect, these investors will effectively control the election of our board
of directors.

    REGISTRATION RIGHTS

    The parties to the purchasers rights agreement, subject to some conditions,
have registration rights with respect to shares of common stock, including
shares of common stock issuable upon conversion or redemption of shares of
series F preferred stock or upon conversion of shares of series B preferred
stock, series C preferred stock, or series D preferred stock. These purchasers
have, subject to some conditions, demand and "piggy-back" registration rights.
The purchasers rights agreement provides that each purchaser of stock is subject
to lock-up restrictions in the event of a public offering of our securities.

    RESTRICTIONS ON TRANSFER

    Our outstanding common stock (including shares issued pursuant to options)
and each series of preferred stock are subject to restrictions on transfer.
Holders of common stock and each series of preferred stock that are parties to
the purchasers rights agreement, subject to some exceptions, may not transfer
their shares without first giving us the opportunity to purchase the shares. In
addition, subject to some exceptions, the holders of common stock or any series
of preferred stock that are parties to the purchasers rights agreement may not
transfer their shares without first giving the other purchasers under the
purchasers rights agreement the opportunity to participate in the transfer.

    PRE-EMPTIVE RIGHTS

    Holders of our common stock and each series of preferred stock that are
parties to the purchasers rights agreement have the right to purchase a pro rata
portion of any common stock or preferred stock that we propose to sell and
issue, subject to some exceptions. These pre-emptive rights do not apply to the
offering and will terminate immediately upon completion of the offering.

    SIZE OF THE BOARD OF DIRECTORS

    The purchasers rights agreement provides that so long as at least 6,666,667
shares of series F preferred stock remain outstanding, the holders of series F
preferred stock are entitled to elect and remove directors in accordance with
our restated certificate of incorporation. In the event that less than 6,666,667
shares of series F preferred stock remain outstanding, but BTI Ventures L.L.C.
and its affiliates, which include KKR, beneficially own at least 10% of our
outstanding common stock, BTI has the right to nominate the number of persons to

    For so long as at least 8,532,394 shares of series B preferred stock,
series C preferred stock and series D preferred stock remain outstanding, the
holders of this stock, voting together as a class, are entitled to elect and
remove directors pursuant to our restated certificate of incorporation.

respect to all shares of common stock held by him. Shares of common stock
subject to options currently exercisable or exercisable within 60 days of

                      DESCRIPTION OF CERTAIN INDEBTEDNESS

SENIOR CREDIT FACILITY

    In December 1999, we entered into a credit agreement with a syndicate of
banks, financial institutions and other entities arranged by Lehman Commercial
Paper, Inc. The agreement includes a seven year, $50.0 million term loan
facility and a seven year $25.0 million revolving credit loan facility.

    In February 2000, we amended these term loan and revolving credit loan
facilities, resulting in a stated principal amount of $125.0 million, of which
$25.0 million is provided for a reducing revolver and $100.0 million for
multi-draw term loans. The revolver is available for general corporate purposes
of our subsidiaries and the term loans are to be used to finance
telecommunications equipment, inventory, network assets and back office systems.
These senior credit facilities are secured by a perfected first priority
security interest in substantially all of our assets and capital stock and
contain a number of financial and operational covenants with which we must
comply. Among other things, the covenants require us to comply with specified
financial ratios and tests, including minimum revenues, minimum EBITDA/maximum
EBITDA losses, minimum access lines, senior secured debt to total capitalization
ratio, maximum capital expenditures, maximum leverage ratios, minimum fixed
charge coverage ratios and pro forma debt service coverage ratios. The covenants
restrict our ability to incur additional debt, make distributions on or redeem
our capital stock, create liens or negative pledges with respect to our assets,
make investments, issue, sell or allow distributions on capital stock of our
subsidiaries, prepay or defease specified indebtedness, enter into transactions
with affiliates, enter into specified hedging arrangements, merge, consolidate
or sell our assets or engage in any business other than telecommunications.

    The loans must be repaid over a seven-year period commencing in
December 2003. Interest payments are due, at our option, either quarterly in the
case of base rate (prime based) draws or at the end of the relevant interest
period in the case of eurodollar draws. Interest will accrue at a lower rate if
we meet specified financial tests. In addition, we must pay a fee based on the
average daily unused committed portion of the credit facilities. This fee is
payable quarterly in arrears and is calculated at a rate of between 0.75% and
1.25% per annum depending upon the percentage of unused credit in the
facilities.


    We are currently renegotiating the terms of our existing senior credit
facility, including an increase in the size of the facility and making
corresponding changes to the financial covenants.


14% SENIOR NOTES DUE 2008

    In June 1998 we issued senior notes with a principal of $115 million along
with warrants to purchase 2,530,473 shares of common stock at $0.006 per share.
These notes, which are senior obligations, bear interest at the rate of 14% per
annum, payable semi-annually in arrears on June 15 and December 15. Payments on
these notes began on December 15, 1998.

    The senior notes are not redeemable at our option prior to June 15, 2003,
except that prior to June 15, 2003 we may redeem up to 35% of the originally
issued aggregate principal amount of the notes at a rate of 114% of the
principal amount thereof on the redemption date, plus accrued and unpaid
interest and liquidated damages, if any, with the net cash proceeds of one or
more public or private sales of common stock or preferred stock, provided that
at least 65% of the senior notes remain outstanding after the redemption. At any
time on or after June 15, 2003, the senior notes are redeemable at our option,
in whole or in part, at a premium declining ratably to par on June 15, 2006.

    The senior note indenture provides that, in the event of a change of control
of us, we will be required to make an offer to purchase in cash all or any part
of the outstanding senior notes at a price of 101% of the aggregate principal
amount thereof plus accrued and unpaid interest and liquidated damages, if any.

                                       70
<PAGE>
    The senior notes indenture contains restrictive covenants that, among other
things, impose on our ability and our restricted subsidiaries' ability to incur
additional indebtedness, merge, consolidate, sell or dispose of all or
substantially all of our assets, issue some kinds of preferred stock, pay cash
dividends or make other distributions on account of our equity interests,
repurchase equity interests or subordinated indebtedness and make other
restricted payments, create liens, enter into transactions with affiliates,
engage in any business other than telecommunications, enter into sale and
leaseback transactions and sell assets.

                          DESCRIPTION OF CAPITAL STOCK


    Upon completion of the offering, our authorized capital stock will consist
of 150,000,000 shares of common stock, $.001 par value per share, and 10,000,000
shares of preferred stock, $.001 par value per share.


COMMON STOCK


    As of March 31, 2000 without giving effect to the exercise by an affiliate
of KKR of its options to invest an additional $50.0 million in our company or to
the conversion of all outstanding shares of our preferred stock into shares of
common stock, there were 8,589,599 shares of common stock outstanding held of
record by 86 stockholders. After giving effect to the affiliate of KKR's
exercise of its options and the conversion of our preferred stock, as of
March 31, 2000, there were 82,736,734 shares of common stock held of record by
259 stockholders. The holders of common stock are entitled to one vote for each
share held of record on all matters submitted to a vote of the stockholders.
Subject to preferences that may be applicable to any outstanding shares of
preferred stock, the holders of common stock are entitled to receive ratably
those dividends as may be declared by the board of directors out of funds
legally available therefor. In the event of a liquidation, dissolution or
winding up, holders of the common stock are entitled to share ratably in all
assets remaining after payment of liabilities and the liquidation preferences of
any outstanding shares of preferred stock. Holders of common stock have no
preemptive rights and no right to convert their common stock into any other
securities. There are no redemption or sinking fund provisions applicable to the
common stock. All outstanding shares of common stock are, and all shares of
common stock to be outstanding upon completion of the offering will be,
fully-paid and nonassessable.


PREFERRED STOCK


    There will be no shares of preferred stock outstanding upon completion of
the offering. Our certificate of incorporation, as amended and restated prior to
the closing of the offering, will provide our board of directors with the
authority, without further action by the stockholders, to issue up to
10,000,000 shares of preferred stock, $.001 par value, in one or more series and
to fix the powers, preferences, privileges, rights and qualifications,
limitations or restrictions thereof, including dividend rights, conversion
rights, voting rights, terms of redemption, liquidation preferences, sinking
fund terms and the number of shares constituting any series or the designation
of the series, without any further vote or action by stockholders. We believe
that the board of directors' authority to set the terms of, and our ability to
issue, preferred stock will provide flexibility in connection with possible
financing transactions in the future. The issuance of preferred stock, however,
could adversely affect the voting power of holders of common stock, and the
likelihood that the holders will receive dividend payments and payments upon
liquidation and could have the effect of delaying, deferring or preventing a
change in control in us. We have no present plan to issue any shares of
preferred stock.


WARRANTS

    We have outstanding warrants to purchase up to 2,530,473 shares of common
stock at an exercise price of $0.006 per share. These warrants are currently
exercisable and expire on June 15, 2008. The warrant agreement governing these
warrants provides the holders of the warrants with customary

                                       71
<PAGE>
antidilution protections. In addition, holders of these warrants have demand and
piggyback registration rights with respect to the exercise of their warrants and
the resale of the underlying shares. Prior to exercising their warrants, the
warrant holders do not have any voting rights relating to our company.

ANTI-TAKEOVER EFFECTS OF OUR CERTIFICATE OF INCORPORATION AND BYLAWS AND
  DELAWARE GENERAL CORPORATION LAW

    OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION AND BYLAWS AND
DELAWARE GENERAL CORPORATION LAW.  Prior to the completion of the offering, we
will amend and restate our certificate of incorporation and bylaws. Certain
provisions of Delaware law and our amended and restated certificate of
incorporation and bylaws could make the following more difficult:

    - the acquisition of us by means of a tender offer;

    - acquisition of us by means of a proxy contest or otherwise; or

    - the removal of our incumbent officers and directors.

    These provisions, summarized below, are expected to discourage certain types
of coercive takeover practices and inadequate takeover bids. These provisions
are also designed to encourage persons seeking to acquire control of us to first
negotiate with our board. We believe that the benefits of increased protection
of the potential ability to negotiate with the proponent of an unfriendly or
unsolicited proposal to acquire or restructure us outweigh the disadvantages of
discouraging these proposals because negotiation of these proposals could result
in an improvement of their terms. Moreover, each of the provisions summarized
below cannot be amended or removed from our amended and restated certificate of
incorporation or our bylaws without the vote of a supermajority of our
stockholders.

    ELECTION AND REMOVAL OF DIRECTORS.  Our board of directors will be divided
into three classes. The directors in each class will serve for a three-year
term, one class being elected each year by our stockholders. This system of
electing and removing directors may tend to discourage a third party from making
a tender offer or otherwise attempting to obtain control of us because it
generally makes it more difficult for stockholders to replace a majority of the
directors.

    In addition, our bylaws will provide that, except as otherwise provided by
law or our certificate of incorporation, newly created directorships resulting
from an increase in the authorized number of directors or vacancies on the board
may be filled only by a majority of the directors then in office, though less
than a quorum is then in office. Our certificate of incorporation will also
provide that the authorized number of directors may be changed only by a
resolution of our board.

    STOCKHOLDER MEETINGS.  Under our certificate of incorporation and bylaws,
only the chairman of the board, the chief executive officer, the president or a
majority of the board of directors will be permitted to call special meetings of
stockholders.

    REQUIREMENTS FOR ADVANCE NOTIFICATION OF STOCKHOLDER NOMINATIONS AND
PROPOSALS.  Our bylaws will establish advance notice procedures with respect to
stockholder proposals and the nomination of candidates for election as
directors, other than nominations made by or at the direction of the board of
directors or a committee of the board.

    DELAWARE ANTI-TAKEOVER LAW.  We are subject to Section 203 of the Delaware
General Corporation Law, an anti-takeover law. In general, Section 203 prohibits
a publicly held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years following the date
the person became an interested stockholder, unless the "business combination"
or the transaction in which the person became an interested stockholder is
approved in a prescribed manner. Generally, a "business combination" includes a
merger, asset or stock sale, or other transaction resulting in a financial
benefit to the interested stockholder. Generally, an "interested stockholder" is
a person who, together with affiliates and associates, owns or within three
years prior to

                                       72
<PAGE>
the determination of interested stockholder status, did own, 15% or more of a
corporation's voting stock. The existence of this provision may have an
anti-takeover effect with respect to transactions not approved in advance by the
board of directors, including discouraging attempts that might result in a
premium over the market price for the shares of common stock held by
stockholders.

    ELIMINATION OF STOCKHOLDER ACTION BY WRITTEN CONSENT.  Upon the completion
of the offering, our certificate of incorporation will eliminate the right of
stockholders to act by written consent without a meeting, unless the consent is
unanimous. This provision may have the effect of discouraging, delaying or
making more difficult a change in control of our company or preventing the
removal of incumbent directors even if a majority of our stockholders were to
deem such an action to be in our best interests.

TRANSFER AGENT AND REGISTRAR

    UMB Bank, n.a. has been appointed as the transfer agent and registrar for
our common stock.

                        SHARES ELIGIBLE FOR FUTURE SALE

    If our stockholders sell substantial amounts of our common stock, including
shares issued upon the exercise of outstanding options or warrants, in the
public market following the offering, the market price of our common stock could
decline. These sales also might make it more difficult for us to sell equity or
equity-related securities in the future at a time and price that we deem
appropriate.


    Upon completion of the offering, we will have outstanding an aggregate of
          shares of our common stock, assuming no exercise of the underwriters'
over-allotment option and no exercise of outstanding options or warrants. Of
these shares, all of the shares sold in the offering will be freely tradeable
without restriction or further registration under the Securities Act, unless the
shares are purchased by "affiliates" as that term is defined in Rule 144 under
the Securities Act. This leaves           shares eligible for sale in the public
market as follows:

</TABLE>


    In addition, subject to volume limitations, 2,530,473 shares issuable upon
the exercise of our outstanding warrants, are currently eligible for sale in the
public market and are not subject to lock-ups.

RULE 144

    In general, under Rule 144 as currently in effect, a person who has
beneficially owned shares of our common stock for at least one year would be
entitled to sell within any three-month period a number of shares that does not
exceed the greater of:


    - 1% of the number of shares of our common stock then outstanding, which
      will equal approximately         shares immediately after the offering; or


    - the average weekly trading volume of our common stock on the Nasdaq
      National Market during the four calendar weeks preceding the filing of a

affiliates at any time during the three months preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an affiliate, is
entitled to sell those shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.

LOCK-UP AGREEMENTS

    All of our officers and directors and stockholders holding in aggregate more

have entered into lock-up agreements under which they agreed not to transfer or
dispose of, directly or indirectly, any shares of our common stock or any

common stock, for a period of 180 days after the date of this prospectus,
without the prior written consent of Lehman Brothers Inc. and Bear, Stearns &
Co. Inc. on behalf of the underwriters.


    In addition to the 180-day lock-up described above, all of our stockholders
with the exception of persons who became stockholders through the exercise of
employee stock options, all of whom held in the aggregate less than 2% of our
outstanding common stock as of March 31, 2000, have entered into the purchasers
rights agreement, which limits their ability to pledge or transfer their shares
of our common stock until August 5, 2002. In addition, Messrs. David E. Scott,
Jeffrey D. Shackelford, Gary L. Chesser, David W. Vranicar, Donald M. Goldman,
Bradley A. Moline and Gregory C. Lawhon, may not transfer shares issued or
issuable upon the exercise of stock options held by them for a period of five
years from the date their respective options were granted. These limitations are
subject to exceptions set forth in the purchasers rights agreement as exempt
transfers.



    In addition, 25 other key employees have each entered into a management
stockholders agreement, under which they have agreed not to transfer shares
received upon exercise of their respective options for a period of five years
from the date their respective options were granted. These limitations are
subject to exceptions set forth in their management stockholders agreements.


    All of our employees who have been granted stock options under our employee

transfer any shares of our common stock for a period of 180 days after our
completion of a public offering of our stock if we request. We intend to make
this request.

stock in connection with a compensatory stock or option plan or other written
agreement is eligible to resell those shares 90 days after we became a reporting
company under the Securities Exchange Act of 1934 in reliance on Rule 144, but
without compliance with some of the restrictions, including the holding period,
contained in Rule 144. We have been a reporting company under the Securities
Exchange Act since March 1999.

    Following the offering, we intend to file a registration statement on
Form S-8 under the Securities Act covering approximately 27,100,000 shares of
common stock issued or issuable upon the exercise of stock options, subject to
outstanding options or reserved for issuance under our employee and director
stock benefit plans. Accordingly, shares registered under the registration
statement will, subject to Rule 144 provisions applicable to affiliates, be
available for sale in the open market, except to the extent that the shares are
subject to vesting restrictions or the contractual restrictions described above.

              CERTAIN UNITED STATES FEDERAL TAX CONSIDERATIONS FOR
                           NON-UNITED STATES HOLDERS

    This is a general discussion of certain United States federal tax
consequences of the acquisition, ownership, and disposition of our common stock
by a holder that, for U.S. federal income tax purposes, is not a U.S. person as
we define that term below. A holder of our common stock who is not a U.S. person
is a non-U.S. holder. We assume in this discussion that you will hold our common
stock issued pursuant to the offering as a capital asset (generally, property
held for investment). We do not discuss all aspects of U.S. federal taxation
that may be important to you in light of your individual investment
circumstances, such as special tax rules that would apply to you, for example,
if you are a dealer in securities, financial institution, bank, insurance
company, tax-exempt organization, partnership or owner of more than 5% of our
common stock. Our discussion is based on current provisions of the Internal
Revenue Code of 1986, as amended, Treasury regulations, judicial opinions,
published positions of the U.S. Internal Revenue Service and other applicable
authorities, all as in effect on the date of this prospectus and all of which
are subject to differing interpretations or change, possibly with retroactive
effect. We have not sought, and will not seek, any ruling from the Internal
Revenue Service or opinion of counsel with respect to the tax consequences
discussed in this prospectus, and there can be no assurance that the Internal
Revenue Service will not take a position contrary to the tax consequences
discussed below or that any position taken by the Internal Revenue Service would
not be sustained. We urge you to consult your tax advisor about the U.S. federal
tax consequences of acquiring, holding, and disposing of our common stock, as
well as any tax consequences that may arise under the laws of any foreign,
state, local, or other taxing jurisdiction.

    For purposes of this discussion, a U.S. person means any one of the
following:

    - a citizen or resident of the U.S.

    - a corporation, partnership, or other entity created or organized in the
      U.S. or under the laws of the U.S. or of any political subdivision of the
      U.S.

    - an estate, the income of which is includible in gross income for U.S.
      federal income tax purposes regardless of its source.

    - a trust, the administration of which is subject to the primary supervision
      of a U.S. court and that has one or more U.S. persons who have the
      authority to control all substantial decisions of the trust.

DIVIDENDS

    Dividends paid to a non-U.S. holder will generally be subject to withholding
of U.S. federal income tax at the rate of 30%. If, however, the dividend is
effectively connected with the conduct of a trade or business of the U.S. by the
non-U.S. holder, the dividend will be subject to U.S. federal income tax imposed
on net income on the same basis that applies to U.S. persons generally, and, for
corporate holders under certain circumstances, the branch profits tax. Non-U.S.
holders should consult any applicable income tax treaties that may provide for a
reduction of, or exemption from, withholding taxes. For purposes of determining
whether tax is to be withheld at a reduced rate as specified by a treaty, we
generally will presume that dividends we pay on or before December 31, 2000, to
an address in a foreign country are paid to a resident of that country.

    Under recently finalized Treasury regulations, which in general apply to
dividends that we pay after December 31, 2000, to obtain a reduced rate of
withholding under a treaty, a non-U.S. holder generally will be required to
provide certification as to that non-U.S. holder's entitlement to treaty
benefits. These regulations also provide special rules to determine whether, for
purposes of applying a treaty, dividends that we pay a non-U.S. holder that is
an entity should be treated as paid to holders of interests in that entity.

                                       76
<PAGE>
GAIN ON DISPOSITION

    A non-U.S. holder will generally not be subject to United States federal
income tax, including by way of withholding, on gain recognized on a sale or
other disposition of our common stock unless any one of the following is true:

    - the gain is effectively connected with the conduct of a trade or business
      in the U.S. by the non-U.S. holder

    - the non-U.S. holder is a nonresident alien individual present in the U.S.
      for 183 or more days in the taxable year of the disposition and certain
      other requirements are met

    - the non-U.S. holder is subject to tax pursuant to provisions of the U.S.
      federal income tax law applicable to certain U.S. expatriates

    - we are or have been during certain periods a "United States real property
      holding corporation" for U.S. federal income tax purposes.

    We believe that we are not currently and will not become a United States
real property holding corporation.

    Gain that is effectively connected with the conduct of a trade or business
in the U.S. by the non-U.S. holder will be subject to the U.S. federal income
tax imposed on net income on the same basis that applies to U.S. persons
generally, and, for corporate holders under certain circumstances, the branch
profits tax, but will generally not be subject to withholding. Non-U.S. holders
should consult any applicable income tax treaties that may provide for different
rules.

UNITED STATES FEDERAL ESTATE TAXES

    Our common stock that is owned or treated as owned by an individual who is
not a citizen or resident of the U.S., as specially defined for U.S. federal
estate tax purposes, on the date of that person's death will be included in his
or her estate for U.S. federal estate tax purposes, unless an applicable estate
tax treaty provides otherwise.

INFORMATION REPORTING AND BACKUP WITHHOLDING

    Generally, we must report annually to the Internal Revenue Service and to
each non-U.S. holder the amount of dividends that we paid to a holder, and the
amount of tax that we withheld on those dividends. This information may also be
made available to the tax authorities of a county in which the non-U.S. holder
resides.

    Under current U.S. Treasury regulations, U.S. information reporting
requirements and backup withholding tax will generally not apply to dividends
that we pay on our common stock to a non-U.S. holder at an address outside the
U.S. Payments of the proceeds of a sale or other taxable disposition of our
common stock by a U.S. office of a broker are subject to both backup withholding
at a rate of 31% and information reporting, unless the holder certifies as to
its non-U.S. holder status under penalties of perjury or otherwise establishes
an exemption. Information reporting requirements, but not backup withholding
tax, will also apply to payments of the proceeds of a sale or other taxable
disposition of our common stock by foreign offices of U.S. brokers or foreign
brokers with certain types of relationships to the U.S. unless the broker has
documentary evidence in its records that the holder is a non-U.S. holder and
certain other conditions are met or the holder otherwise established an
exemption.

    Backup withholding is not an additional tax. Any amounts that we withhold
under the backup withholding rules will be refunded or credited against the
non-U.S. holder's U.S. federal income tax liability if certain required
information is furnished to the Internal Revenue Service.

    The U.S. Treasury Department has promulgated final regulations regarding the
withholding and information reporting rules discussed above. In general, those
regulations do not significantly alter the substantive withholding and
information reporting requirements but unify current certification procedures
and forms and clarify reliance standards. The final regulations are generally
effective for payments made after December 31, 2000, subject to transition
rules.

</TABLE>

    The underwriting agreement provides that the underwriters' obligations to
purchase shares of common stock depend on the satisfaction of the conditions
contained in the underwriting agreement, and that if any of the shares of common
stock are purchased by the underwriters under the underwriting agreement, then
all of the shares of common stock the underwriters have agreed to purchase under
the underwriting agreement must be purchased. The conditions contained in the
underwriting agreement include that:

    - the representations and warranties made by us to the underwriters are
      true;

    - there is no material change in the financial markets; and

    - we deliver customary closing documents to the underwriters.

    The representatives have advised us that the underwriters propose to offer
the shares of common stock directly to the public at the public offering price
set forth on the cover page of this prospectus, and to selected dealers, who may
include the underwriters, at such public offering price less a selling
concession not in excess of $  per share. The underwriters may allow, and the
selected dealers may reallow, a concession not in excess of $  per share to
brokers and dealers. After the offering, the underwriters may change the
offering price and other selling terms.


    We estimate that our share of the total expenses of the offering, including
the underwriting discount will be approximately $   million.



    We have granted to the underwriters an option to purchase up to an aggregate
of         additional shares of common stock, exercisable to cover any
over-allotments, if any, at the public offering price less the underwriting
discount shown on the cover page of this prospectus. The underwriters may
exercise this option at any time, and from time to time, until 30 days after the
date of the underwriting agreement. To the extent that the underwriters exercise
this option, each underwriter will be committed, so long as the conditions of
the underwriting agreement are satisfied, to purchase a number of additional
shares of common stock proportionate to that underwriter's initial commitment as
indicated in the preceding table, and we will be obligated, under such
over-allotment option, to sell the shares of common stock to the underwriters.


                                       78
<PAGE>
    We and our directors, officers, and all current stockholders have agreed not
to offer to sell, sell or otherwise dispose of, directly or indirectly, any
shares of capital stock or any securities that may be converted into or
exchanged for any shares of capital stock for a period of 180 days period from
the date of the prospectus without the prior written consent of Lehman
Brothers Inc. and Bear, Stearns & Co. Inc., except that we may issue, and grant
options to purchase, shares of common stock under our option plans.

    Before this offering, there has been no public market for the shares of
common stock. The initial public offering price will be negotiated between the
representatives and us. In determining the initial public offering price of the
common stock, the representatives will consider, among other things and in
addition to prevailing market conditions:

    - our historical performance and capital structure;

    - estimates of our business potential and earning prospects;

    - an overall assessment of our management; and

    - the consideration of the above factors in relation to market valuations of
      companies in related businesses.

    Thomas Weisel Partners LLC, one of the representatives, was organized and
registered as a broker/dealer in December 1998. Since December 1998, Thomas
Weisel Partners has acted as a lead or co-manager on numerous public offerings
of equity securities. Thomas Weisel Partners does not have any material
relationship with us or any of our officers, directors or other controlling
persons, except with respect to its contractual relationship with us under the
underwriting agreement entered into in connection with this offering.

    Fidelity Capital Markets, a division of National Financial Services
Corporation, is acting as an underwriter in this offering, and will be
facilitating electronic distribution of information through the Internet,
intranet and other proprietary technology.


    Our application to list our common stock on the Nasdaq National Market under
the trading symbol "BRCH" has been approved.


    We have agreed to indemnify the underwriters against liabilities related to
the offering, including liabilities under the Securities Act and liabilities
incurred in connection with the directed share program referred to below, and to
contribute to payments that the underwriters may be required to make for these
liabilities.

    Until the distribution of the common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters and
selling group members to bid for and purchase shares of common stock. As an
exception to these rules, the representatives are permitted to engage in
transactions that stabilize the price of common stock. These transactions may
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of the common stock.

    The underwriters may create a short position in the common stock in
connection with the offering. This means that they may sell more shares of
common stock than are shown on the cover page of this prospectus. If the
underwriters create a short position, then the representatives may reduce that
short position by purchasing common stock in the open market. The
representatives also may elect to reduce any short position by exercising all or
part of the over-allotment option. The underwriters have informed us that the
they do not intend to confirm sales to discretionary accounts that exceed 5% of
the total number of shares of common stock offered by them.

    The representatives also may impose a penalty bid on underwriters and
selling group members. This means that, if the representatives purchase shares
of common stock in the open market to reduce the underwriters' short position or
to stabilize the price of the common stock, they may reclaim the

                                       79
<PAGE>
amount of the selling concession from the underwriters and selling group members
who sold those shares as part of the offering.

    In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid could have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
an offering.

    Neither we nor any of the underwriters make any representation or prediction
as to the direction or magnitude of any effect that the transactions described
above may have on the price of the common stock. In addition, neither we nor any
of the underwriters makes any representation that the representatives will
engage in these stabilizing transactions or that any transaction, once
commenced, will not be discontinued without notice.


    At our request, Lehman Brothers Inc. has reserved up to 1,250,000 shares of
the common stock offered by this prospectus, for sale pursuant to a directed
share program to our employees, directors and friends at the initial public
offering price set forth on the cover page of this prospectus. These persons
must commit to purchase no later than the close of business on the day following
the date of this prospectus. The number of shares available for sale to the
general public will be reduced to the extent these persons purchase the reserved
shares.


    Certain of the representatives have from time to time provided investment
banking, financial advisory and other services to us for which these
representatives received customary fees and commissions. Lehman Brothers Inc.
acted as lead arranger of our senior credit facility and its affiliate, Lehman
Commercial Paper Inc., is the administrative agent of the senior credit
facility. In addition, First Union Securities, Inc. is a lender under our senior
credit facility. Lehman Brothers Inc. was an initial purchaser of our senior
notes. In addition, Lehman Brothers Inc. acted as placement agent in connection
with the private placement of shares of our series F preferred stock in
August 1999. Lehman Brothers Inc. has also served as the solicitation agent in
connection with the related solicitation of consents from holders of our senior
notes.

    The validity of the shares of common stock offered hereby will be passed
upon for us by our counsel, Latham & Watkins, 885 Third Avenue, New York, New
York 10022. At the time of completion of the offering, attorneys of Latham &
Watkins are expected to indirectly own in the aggregate less than 1% of our
common stock. Various regulatory matters in connection with the offering are
being passed upon for us by Dickstein Shapiro Morin & Oshinsky LLP, 2101 L
Street, NW, Washington, D.C. 20037. Various legal matters relating to the common
stock will be passed upon for the underwriters by Simpson Thacher & Bartlett 425
Lexington Avenue, New York, New York 10017. Certain partners of Simpson Thacher

indirect interest, through limited partnerships, through KKR 1996 Fund L.P., in
less than 1% of our common stock. In addition, Simpson Thacher & Bartlett has in
the past provided, and may continue to provide, legal services to KKR and its

                         REPORT OF INDEPENDENT AUDITORS

THE BOARD OF DIRECTORS AND STOCKHOLDERS
BIRCH TELECOM, INC.

    We have audited the accompanying consolidated balance sheets of Birch
Telecom, Inc. (Birch) as of December 31, 1998 and 1999, and the related
consolidated statements of operations, stockholders' equity (deficit) and cash
flows for each of the three years in the period ended December 31, 1999. These
financial statements are the responsibility of Birch's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Birch
Telecom, Inc. at December 31, 1998 and 1999, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1999, in conformity with accounting principles generally accepted
in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. THE COMPANY

    Birch Telecom, Inc. was incorporated on December 23, 1996, as a Delaware
corporation for the purpose of providing local, long distance, Internet access,
and other communications services to business and residential customers. The
consolidated financial statements of Birch Telecom, Inc. include the accounts of
Birch Telecom, Inc. and the accounts of its wholly-owned subsidiaries
(collectively, Birch). Birch currently serves certain markets in Missouri,
Kansas and Texas. Birch's business is highly competitive and is subject to
various federal, state and local regulations.

    Birch was in the development stage for the period from December 23, 1996
(date of inception) to February 10, 1998. Accordingly, Birch had no operating
revenue and incurred operating losses and operating cash flow deficits during
that period.


    INTERIM FINANCIAL STATEMENTS



    The accompanying interim unaudited financial statements as of March 31, 2000
and for the three-month periods ended March 31, 1999 and 2000 have been prepared
in accordance with generally accepted accounting principles for interim
financial information and the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the three months ended March 31, 2000 are
not necessarily indicative of the results that may be expected for the year
ended December 31, 2000.



2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


    CASH AND CASH EQUIVALENTS

    For purposes of reporting cash flows, Birch includes as cash and cash
equivalents highly liquid investments with original maturities of three months
or less.

    REVENUE RECOGNITION

    Revenue for communications services is recognized when customers use the
associated services. Equipment revenue is recognized when systems or services
are substantially complete. Revenue on billings to customers in advance of
providing services is deferred and recognized when earned. Customers are not
charged fees to activate initial service.

    COST OF SERVICES

    Cost of services includes local and long-distance services purchased from
incumbent local exchange carriers, interexchange carriers and certain providers
of fiber optic telephone networks. Cost of services also includes costs
associated with the sale and installation of telephone systems.

    INVENTORY

    Inventory is carried at the lower of average cost or market determined on a
first-in, first-out basis and consists primarily of parts and equipment used in
the maintenance and installation of telephone systems.

    ADVERTISING COSTS

    Advertising costs are expensed as incurred and totaled $895,000 in 1998 and
$3.0 million in 1999. There were no advertising costs in 1997.

    PROPERTY AND EQUIPMENT

    Property and equipment is stated at cost and depreciated using the
straight-line method over the following estimated useful lives of the assets:

<TABLE>
<CAPTION>
                                                               YEARS
                                                              --------
<S>                                                           <C>
Communications network......................................    2-10
Buildings, furniture, fixtures and equipment................    2-40
</TABLE>

    GOODWILL AND OTHER INTANGIBLES

    Goodwill represents the excess of the purchase price paid over the fair
value of the net assets acquired in Birch's acquisitions. Goodwill is being
amortized over 25 years using the straight-line method. Accumulated amortization
on goodwill totaled $599,000 at December 31, 1998 and $1.4 million at
December 31, 1999.

    Other intangibles consist primarily of customer lists related to Birch's
acquisitions, deferred financing costs and deferred line installation costs.
Customer lists are amortized over 5 years using the straight-line method. The
deferred financing costs are amortized over 5 to 10 years, the term of the
associated financing, using the straight-line method. Deferred line installation
costs are being amortized over 2 years, the approximate average life of customer
contracts, using the straight-line method (see Note 6).

    Birch reviews its long-lived assets in accordance with Statement of
Financial Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-lived Assets and Long-lived Assets to be Disposed of," for impairment
whenever events or changes in circumstances indicate that the carrying amount of
an asset may not be recoverable. If such events or changes in circumstances are
present, a loss is recognized if the carrying value of the asset is in excess of
the sum of the undiscounted cash flows expected to result from the use of the
asset and its eventual disposition. An impairment loss is measured as the amount
by which the carrying amount of the asset exceeds the fair value of the asset.

    INCOME TAXES

    Birch accounts for income taxes in accordance with SFAS No. 109, "Accounting
for Income Taxes." Birch recognizes deferred tax assets and liabilities for the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax assets and
liabilities are determined based on the differences between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse. Net
deferred tax assets are reduced by a valuation allowance when appropriate (see
Note 14). Deferred tax assets and liabilities are adjusted for the effects of
changes in tax laws and rates on the date of enactment.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    STOCK OPTIONS

    Birch has adopted the disclosure provisions of SFAS No. 123, "Accounting for
Stock-Based Compensation," which establishes a fair value based method for the
financial reporting of its stock-based employee compensation plans. However, as
allowed by SFAS No. 123, Birch has elected to continue to measure compensation
using the intrinsic value based method as prescribed by Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees." Under this
method, compensation is measured as the difference between the market value of
the stock on the grant date, less the amount required to be paid for the stock.
The difference, if any, is charged to expense over the vesting period of the
options. The estimated market value used for the stock options granted was
determined on a periodic basis by Birch's board of directors. In accordance with
APB No. 25, Birch has recorded no compensation expense related to options
granted because the exercise price is equal to the estimated market value of the
stock on the date of grant (see Note 15).

    FAIR VALUES OF FINANCIAL INSTRUMENTS

    The carrying amount of cash and cash equivalents approximates fair value due
to the short maturity of the instruments. The fair value of Birch's pledged
securities was $38 million at December 31, 1998 and $23.3 million at
December 31, 1999. The fair value of Birch's senior notes is estimated to be
$106 million at December 31, 1998 and $115 million at December 31, 1999 based on
the quoted market rates for the debt. The fair value of other long-term debt,
accounts receivable, accounts payable and accrued expenses approximates the
recorded value.

    USE OF ESTIMATES IN FINANCIAL STATEMENTS

    The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts in the consolidated financial
statements and accompanying notes. Actual results could differ from those
estimates.

    LOSS PER SHARE

    The net loss per share amount reflected on the consolidated statement of
operations is based on the weighted-average number of common shares outstanding.
Stock options and convertible preferred stock are anti-dilutive, and therefore
excluded from the computation of earnings per share. In the future, these stock
equivalents may become dilutive.

    RECLASSIFICATIONS


    Certain items in the 1997, 1998 and 1999 consolidated financial statements
have been reclassified to be consistent with the classification in the 2000
consolidated financial statements.


    NEW ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities," which
supersedes SFAS No. 80, "Accounting for Futures Contracts," SFAS No. 105,
"Disclosure of Information About Financial Instruments with Off-Balance-Sheet
Risk and Financial Instruments with Concentration of Credit

Risk," and SFAS No. 119, "Disclosures about Derivative Financial Instruments and
Fair Value of Financial Instruments," and also amends certain aspects of other
SFAS's previously issued. SFAS No. 133 establishes accounting and reporting
standards for derivative instruments and hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the balance
sheet and measure those instruments at fair value. SFAS No. 133 is effective for
our consolidated financial statements for the year ending December 31, 2001. We
do not expect the impact of SFAS No. 133 to be material in relation to our
consolidated financial statements.


    In December 1999, the Securities and Exchange Commission (SEC) issued Staff
Accounting Bulletin (SAB) No. 101, "Revenue Recognition in Financial
Statements." SAB No. 101 provides guidance on the recognition, presentation and
disclosure of revenue in financial statements. SAB No. 101 is effective for our
consolidated financial statements beginning in the second quarter 2000. We do
not expect the impact of SAB No. 101 to have a material effect in relation to
our consolidated financial statements.



    In March 2000, the FASB issued Interpretation No. 44, "Accounting for
Certain Transactions Involving Stock Compensation: An Interpretation of
Accounting Principles Board (APB) Opinion No. 25" (the FASB Interpretation). The
FASB Interpretation poses and answers 20 separate questions dealing with APB No.
25, "Accounting for Stock Issued to Employees," implementation practice issues.
The FASB Interpretation will be effective beginning July 1, 2000, and we are
currently determining its impact in relation to our consolidated financial
statements.


3. ACQUISITIONS

    In February 1998, Birch merged with Valu-Line Companies, Inc. (Valu-Line) in
a transaction valued at $19.5 million, consisting of $4.75 million in cash,
2,968,750 shares of series A preferred stock having an aggregate liquidation
preference of $4.75 million and 6,250,000 shares of series C preferred stock
having an aggregate liquidation preference of $10.0 million. Since 1982,
Valu-Line has been primarily providing switched long distance services, customer
premises equipment (CPE) sales and services and, since March 1997, local
service.

    In May 1998, Birch acquired Boulevard Phone Company (Boulevard), a shared
tenant service provider in the Kansas City metropolitan area, for $300,000 in
cash and Telesource Communications, Inc. (Telesource), a CPE provider in the
Kansas City metropolitan area, for $325,000 in cash.

    In September 1998, Birch acquired TFSnet, Inc. (TFSnet), an Internet service
provider based in the Kansas City metropolitan area, for $2.65 million.

    In February 1999, Birch acquired American Local Telecommunications, LLC
(ALT), a competitive local exchange carrier based in the Dallas, Texas
metropolitan area. The acquisition included substantially all assets of ALT. The
total purchase price was approximately $1.6 million in cash and $211,000 in
common stock.

    In March 1999, Birch acquired the stock of Capital Communications
Corporation (Capital), a telecommunications equipment provider based in the St.
Louis, Missouri metropolitan area. The total purchase price was approximately
$3.0 million plus additional cash consideration, recorded as additional

purchase price, based on local service lines converted to Birch's service from
Capital's existing customer base, which totaled approximately $161,000 through
December 31, 1999.

    All of the acquisitions referenced above were recorded using the purchase
method of accounting. Accordingly, the operations of each are included in the
consolidated statements of operations and cash flows from the date of
acquisition.

7. DEBT, PLEDGED SECURITIES AND WARRANTS

    During December 1999, Birch completed a $75 million senior credit facility
which increased to $125 million during syndication in February 2000. The
financing provides for a $25 million reducing revolver and $100 million in
multi-draw term loans. The revolver is available for general corporate purposes
of Birch's subsidiaries and the term loans are to be used to finance the
development, design, installation and acquisition of telecommunications
equipment, inventory network assets and back office systems. At Birch's
election, the borrowings bear interest at either the Prime Rate plus a margin
ranging from 1.50% to 2.50% or the London Interbank Offered Rate (LIBOR) plus a
margin ranging from 2.75% to 3.75%. The applicable margins are based upon
Birch's debt to EBITDA ratio, as defined by the senior credit facility. Interest
is paid quarterly in arrears for loans bearing interest based upon Prime and/or
on the last day of each relevant interest period, for periods not in excess of
three months, for LIBOR loans. For LIBOR loans with interest periods of longer
than three months, interest is paid each day which is three months after the
first day of such interest period and the last day of such interest period.
Commitment fees are paid quarterly in arrears on the average unused committed
portion of the senior credit facility, ranging from 0.75% to 1.25%. The
applicable percentages are based upon Birch's average borrowings in relation to
the average borrowing availability, as defined by the senior credit facility.
For the year ended December 31, 1999 commitment fees totaled $25,174. Principal
payments begin March 2003 and the credit facility matures December 30, 2006. The
senior credit facility is secured by a perfected first priority security
interest in substantially all of Birch's assets and capital stock. Deferred
financing costs incurred amounting to $1.5 million at December 31, 1999 are
being amortized over the life of the credit facility using the straight-line
method. Amortization for the year ended December 31, 1999 was not significant.

    During June 1998, Birch completed a $115 million private offering of 14%
senior notes due June 2008 and 115,000 warrants to purchase 2,530,473 shares of
common stock. Interest on the senior notes is payable semi-annually in arrears
on June 15 and December 15 of each year. Warrants are exercisable at $0.006 per
share and expire June 2008. Birch received net proceeds from the senior notes of
$110.2 million and concurrently purchased pledged securities of $44.2 million.
The pledged securities are restricted for interest payments on the senior notes
and, together with the interest accruing thereon, will be used to satisfy such
interest payments through June 2001. Birch classifies its pledged securities,
consisting of $37.8 million at December 31, 1998 and $23.4 million at
December 31, 1999 of

7. DEBT, PLEDGED SECURITIES AND WARRANTS (CONTINUED)
U.S. Treasury securities, as held to maturity recorded at amortized cost and
maturing between six and eighteen months. A portion of the proceeds from the
senior notes, $337,000, was allocated to the warrants, and the resulting debt
discount is being amortized over the life of the debt on the straight-line
method, which does not differ materially from the effective interest method.
Unamortized discount was $319,000 at December 31, 1998 and $285,000 at
December 31, 1999. The amount allocated to the warrants represents the estimated
fair value of the warrants at the date of issuance. Deferred financing costs
incurred amounting to $4.9 million at December 31, 1999 are being amortized over
the life of the senior notes using the straight-line method. Accumulated
amortization on the financing costs totaled $1.5 million at December 31, 1999.
The senior notes rank pari pasu in right of payment to all existing and future
senior indebtedness of Birch and rank senior in the right of payment to all
existing and future subordinated indebtedness of Birch.

    A Registration Statement on Form S-4, registering Birch's 14% senior notes
and exchanging the outstanding senior notes for exchange notes, was declared
effective by the Securities and Exchange Commission (SEC) in March 1999. The
terms and conditions of the exchange notes are identical to those of the senior
notes in all material respects.

    The senior credit facility and the senior notes indenture contain certain
covenants which, among other things, restrict the ability of Birch to incur
additional indebtedness, pay dividends or make distributions of Birch's or its
subsidiaries' stock, enter into sale and leaseback transactions, create liens,
enter into transactions with affiliates or related persons, consolidate, merge
or sell all of its assets. Birch was in compliance with these covenants at
December 31, 1999.

    Birch's debt consisted of the following at December 31, 1998 and 1999:

9. CAPITAL STRUCTURE

    During 1997, $1.8 million of common stock and $18,000 of warrants were sold
to management and equity investors for $1.00 and $0.01 per share, respectively.
The warrants entitled the holders to purchase an additional 1.8 million shares
of common stock at $1.00 per share.

preferred stock at $4.50 per share and $3.5 million of convertible notes
generating net proceeds of $12.4 million, converted all existing common stock to

stock and $10.0 million of series C preferred stock in connection with the
Valu-Line merger. Birch redeemed the series A preferred stock in June 1998. Also
in June 1998, the convertible notes were converted into series B preferred
stock.

    During July and August 1999, Birch issued $10 million of series D preferred
stock and $60 million of series F preferred stock at $4.50 per share. Options
were granted to purchase $25 million of series F preferred stock at $4.75 per
share and $25 million of series F preferred stock at $5.00 per share which
expire on April 13, 2000. Additionally, Birch repurchased $10 million of
series C preferred stock at $4.50 and recapitalized the series B preferred stock
converting it into a new series B preferred stock and a new series E preferred
stock. The series E preferred stock was then redeemed for $8.6 million. Net
proceeds generated from these transactions totaled $44.4 million.


    See note 19 for a description of certain equity transactions occurring
subsequent to year-end 1999.


    AUTHORIZED SHARES

    At December 31, 1999, Birch had shares authorized totaling 80 million shares
of common stock and 55 million shares of preferred stock. The preferred stock
has designations of 8.75 million shares of series B, 8.5 million shares of
series C, 2.2 million shares of series D, 1.9 million shares of series E and
30 million shares of series F.

    RIGHTS

    All shares of preferred stock are convertible into 1.795 shares of common
stock and contain certain voting rights. The common stock also has voting rights
similar to the series C preferred stock. The series B, series D and series F
preferred stock have additional voting rights in certain circumstances.
Additionally, the series F preferred stock contains mandatory redemption rights
based on certain senior management retention. In the event of mandatory
redemption, the shares are redeemable for amounts similar to the liquidation
preference discussed below.

    LIQUIDATION RIGHTS

    Birch's series D and series F preferred stock have a liquidation preference
over the series B and series C preferred stock and common stock at the greater
of (i) the purchase price plus accrued but unpaid dividends or (ii) the amount
the holders would have received upon liquidation if such shares of series D and
series F preferred stock had been converted to common stock immediately prior to
liquidation. Birch's series B preferred stock has a liquidation preference only
over series C preferred stock and common stock at an amount equal to the sum of
the purchase price plus accrued but unpaid dividends. series C preferred stock
has preference only over common stock at an amount equal to the sum of the
purchase price plus accrued but unpaid dividends.

    DIVIDENDS

    The series B preferred stock accrued cumulative compounding dividends at 15%
per annum until the series B was converted and restated into new series B. At
that time, the rights and preferences were amended and restated to remove the
mandatory dividend rights and now the series B cumulates cash dividends at 15%
per annum, amounting to $814,000 at December 31, 1999. The series C preferred
stock has a 10% non-cumulative cash dividend and the series D preferred stock
cumulates

cash dividends at a rate of 15% per annum, totaling $750,000 at December 31,
1999. Only the series F preferred stock contains mandatory dividend rights.
Accrued cash dividends on series F preferred stock totaled $3.6 million at
December 31, 1999, as reflected in stockholders' equity. Common stock dividends,
if any, will be declared at the discretion of Birch's board of directors. Birch
has not paid any cash dividends on common stock since inception and does not
intend to pay any in the foreseeable future. Restrictions contained in the
senior credit facility agreement and the senior notes indenture prohibit Birch
from paying certain dividends on its capital stock.

    On June 23, 1998, Birch paid a stock dividend, in the amount of 0.055 shares
per share, to the holders of Birch's series B preferred stock and series C
preferred stock and 0.031 shares to the holders of common stock as of June 15,

stockholder under a note payable. The note payable was fully repaid in
February 1998.

    Birch acquired notes payable to Valu-Line shareholders totaling $274,000 in
the Valu-Line merger. These notes were fully repaid during 1998.

    A broadcasting company owned by one of the Birch's shareholders rented
office space from Birch for $30,000 during 1998 and $29,187 during 1999. Birch
purchased advertising from the broadcasting company totaling $40,000 in 1998 and

    Total rent expense was $81,000 in 1997, $485,000 in 1998 and $1.5 million in
1999. Birch may renew leases on its corporate offices in terms ranging from
three to ten years at rates approximating the prevailing market. Renewal rentals
are excluded from the table.

    Various suits arising in the ordinary course of business are pending against
Birch. Management cannot predict the final outcome of the actions, but believes
they will not be material to Birch's financial statements.

</TABLE>

    Net income tax benefits of approximately $5.1 million in 1998 and $22.9 in
1999 have been offset by increases in the valuation allowance. At December 31,
1999, Birch had operating loss carryforwards for federal income tax purposes of
approximately $71.9 million, expiring in 2013 and 2014.

    The primary difference that caused the effective tax rate to vary from the
statutory federal income tax rate of 35% was the valuation allowance.

15. STOCK OPTION PLAN

    At December 31, 1997, Birch had granted options to purchase common stock
under the 1997 stock option plan. The options granted had a term of 10 years and
vested over a four-year period. This plan was terminated and superseded in 1998
by the 1998 employee stock option plan. No options were or ever will be
exercised and no shares were or will ever be issued under the terminated and
superseded 1997 stock option plan.

    At December 31, 1998, 9,627 options were exercisable with a weighted average
exercise price of $0.001. At December 31, 1999, 192,905 options were exercisable
with a weighted average exercise price of $1.212.

    The 1998 employee stock option plan authorized the grant of options for up
to 11,121,542 shares of Birch's common stock. The options have a term of
10 years and vest over a four-year period. All options exercised during 1998
were for options granted with an early exercise provision. The shares from
exercised options continue to be subject to the four-year vesting period. No
options expired during 1998 or 1999.

    Options granted in 1998 and 1999 had exercise prices approximating the
market value of the common stock. Exercise prices for options outstanding at
December 31, 1999 ranged from $0.001 to $2.507. The weighted-average remaining
contractual life of those options is 9.4 years. The weighted-average fair values
of options granted during the years ended December 31, 1998 and 1999 equaled
$0.028 and $0.407, respectively. At December 31, 1999, Birch has reserved
2,923,976 shares of common stock for issuance under the 1998 stock option plan.

15. STOCK OPTION PLAN (CONTINUED)
    Birch estimated the fair value of each option grant using the minimum value
method permitted by SFAS No. 123 for entities not publicly traded. Birch used
the following assumptions in the calculation: risk-free interest rate of 5.25%,
expected life of four years and no dividends being paid over the life of the
options. Under the minimum value method, the volatility factor is excluded. Had
compensation cost for the stock based compensation plan been determined as
prescribed by SFAS No. 123, the net loss and loss per common share would have
been as follows for the years ended December 31, 1997, 1998 and 1999:

16. SIGNIFICANT SUPPLIERS

    Birch purchased telephone services from Southwestern Bell Telephone
amounting to 35% of cost of services in 1998 and 65% in 1999. Birch is dependent
upon incumbent telephone companies, such as Southwestern Bell, for the supply of
fiber optic networks that we use. Birch purchased switches and other network
equipment and software from Lucent Technologies amounting to $12.9 million in
1998 and $9.9 million in 1999.

17. YEAR 2000 ISSUE--UNAUDITED

    The Year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of Birch's
computer programs that have date-sensitive software may recognize the date using
"00" as the year 1900 rather than the year 2000. Birch completed all Year 2000
readiness work and experienced no significant problems as a result of the new
year. Birch does not believe it has continued exposure to the Year 2000 problem
and does not expect further costs incurred in relation to the Year 2000 issue to
be substantial.

19. SUBSEQUENT EVENTS

    Since December 31, 1999, Birch has borrowed an additional $40 million
through March 31, 2000 under the term loan portion of the senior credit
facility.


    During March 2000, the following equity transactions occurred:



    - Birch filed a registration statement on Form S-1 with the SEC for an
      underwritten initial public offering of common stock. In connection with
      the filing, Birch's board of directors approved a 1.795-for-1 split of
      common stock. All prior period share and per share information has been
      restated to reflect the split. All outstanding shares of Birch's preferred
      stock will automatically convert into shares of common stock upon
      completion of the proposed offering. Additionally, the conversion ratio on
      the preferred stock has been adjusted in accordance with the 1.795-for-1
      common stock split.



    - BTI Ventures, L.L.C. (BTI), an affiliate of Kohlberg Kravis Roberts & Co.
      (KKR), Birch's largest stockholder, exercised its options to purchase an
      additional 5,263,158 shares of series F preferred stock at $4.75 per share
      and 5,000,000 shares of series F preferred stock at $5.00 per share,
      totaling $50.0 million (see note 9). The transaction was funded and the
      associated shares were issued in April 2000; and



    - Richard Jalkut, a member of Birch's board of directors, agreed to purchase
      47,867 shares of common stock for $200,000, and Mory Ejabat, a member of
      Birch's board of directors, agreed to purchase 119,667 shares of common
      stock for $500,000.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors
Valu-Line Companies, Inc.

    We have audited the accompanying consolidated balance sheet of the Valu-Line
Companies, Inc. (the Company) as of December 31, 1997, and the related
consolidated statements of income and retained earnings, and cash flows for the
year then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.

    We conducted our audit in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Valu-Line
Companies, Inc. at December 31, 1997 and the consolidated results of its
operations and its cash flows for the year then ended in conformity with
accounting principles generally accepted in the United States.

    Total rent expense for 1997 was $56,000.

10. SUBSEQUENT EVENT

    In February 1998, the Company was acquired by Birch Telecom, Inc. for
$19,500,000. Shareholders of the Company received $4,750,000 of cash and
$14,750,000 of preferred stock in Birch Telecom, Inc.

11. YEAR 2000 COMPLIANCE--UNAUDITED

    Year 2000 issues arise from computer programs written using two digits
rather than four to define the applicable year. Any of the Company's computer
programs that have time-sensitive software may recognize a date using 00 as the
year 1900 rather than the year 2000. This could result in a system failure or
miscalculation causing disruptions of operations, including, among other things,
a temporary inability to process transactions, send invoices or engage in
similar normal business activities.

    Based on ongoing assessments, the Company determined that it will be
required to modify or replace portions of its software so that its computer
systems will function properly with respect to dates in the year 2000 and
thereafter. The Company presently believes that with modifications to existing
software and conversions to new software, the year 2000 issue will not pose
significant operational problems for its computer systems. The Company estimates
it will incur minimal expenses to modify and convert its systems and anticipates
completing the year 2000 project by the year ending December 31, 1998.

                          YEAR ENDED DECEMBER 31, 1997

11. YEAR 2000 COMPLIANCE--UNAUDITED (CONTINUED)
    While the Company believes that its systems will be year 2000 compliant,
there can be no assurance until the year 2000 occurs that all systems will
function adequately. In addition, the Company interconnects and uses various
local exchange companies' facilities to service its customers, and such
facilities currently utilize numerous, date-sensitive computer applications. If
these facilities are not year 2000 compliant, or if the systems of other local
exchange companies, long distance carriers and others upon which the Company
relies are not year 2000 compliant, it could have a material effect on the
Company's business, operating results and financial condition.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    We are a Delaware corporation. Reference is made to Section 102(b)(7) of the
Delaware General Corporation Law (the "DGCL"), which enables a corporation in
its original certificate of incorporation or an amendment thereto to eliminate
or limit the personal liability of a director for violations of the director's
fiduciary duty, except (i) for any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) pursuant to Section 174 of the DGCL (providing for liability of directors
for unlawful payments of dividends of unlawful stock purchase or redemptions),
or (iv) for any transaction from which a director derived an improper personal
benefit.

    Reference is also made to Section 145 of the DGCL, which provides that a
corporation may indemnify any person, including an officer or director, who is,
or is threatened to be made, party to any threatened, pending or completed legal
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of such corporation), by
reason of the fact that such person was an officer, director, employee or agent
of such corporation or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, provided such officer,
director, employee or agent acted in good faith and in a manner he reasonably
believed to be in, or not opposed to, the corporation's best interest and, for
criminal proceedings, had no reasonable cause to believe that his conduct was
unlawful. A Delaware corporation may indemnify any officer or director in an
action by or in the right of the corporation under the same conditions, except
that no indemnification is permitted without judicial approval if the officer or
director is adjudged to be liable to the corporation. Where an officer or
director is successful on the merits or otherwise in the defense of any action
referred to above, the corporation must indemnify him against the expenses that
such officer or director actually and reasonably incurred.

                                      II-1
<PAGE>
    Article V of our amended and restated by-laws (filed as Exhibit 3.2)
provides for indemnification of the officers and directors to the full extent
permitted by applicable law.

    The underwriting agreement (Exhibit 1.1) provides for indemnification by the
underwriters of the registrant and its officers and directors for certain
liabilities arising under the Securities Act, or otherwise.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

    The following is a description of all securities that we have sold within
the past three years without registering the securities under the Securities
Act:

    On February 10, 1998, as part of the consideration for our acquisition of
Value-Line, we paid to the principal stockholder of Valu-Line, 2,968,750 shares
of our series A preferred stock and 5,982,746 shares of our series C preferred
stock. These issuances were exempt from registration pursuant to Section 4(2) of
the Securities Act. In June 1998, we repurchased all of the outstanding shares
of our Series A preferred held by Valu-Line's former principal stockholder.

    On March 13, 1998, we completed a private placement to approximately 70
accredited investors of 5,937,500 shares of our series B preferred stock
comprised of shares with an aggregate liquidation preference of $9.5 million and
convertible notes in the aggregate principal amount of $3.5 million. On
June 18, 1998, we converted those notes to 2,307,965 shares of series B
preferred stock. These issuances were exempt from registration pursuant to
Section 4(2) of the Securities Act.

    In connection with this series B preferred stock offering, one stockholder
surrendered 1,500,000 shares of common stock and 1,500,000 warrants exercisable
into shares of common stock in exchange for 1,582,500 shares of series C
preferred stock. One of our officers surrendered 180,000 shares of common stock
and 180,000 warrants exercisable into shares of common stock in exchange for
189,900 shares of series C preferred stock. Another of our officers surrendered
120,000 shares of common stock and 120,000 warrants exercisable into shares of
common stock in exchange for 126,600 shares of series C preferred stock. We then
cancelled the exchanged shares and warrants exercisable into shares of common
stock. These issuances were exempt from registration pursuant to Section 4(2) of
the Securities Act.

    In February 1999, we acquired American Local, a competitive local exchange
carrier based in the Dallas, Texas metropolitan area. The acquisition included
substantially all assets of American Local. The total purchase price was
approximately $1.6 million in cash and $211,000 in common stock, or 126,249
shares. This issuance was exempt from registration pursuant to Section 4(2) of
the Securities Act.

    On July 23, 1999, we completed a private placement to approximately 55 of
our existing investors in series B preferred stock of 2,222,222 shares of series
D preferred stock at a purchase price of $4.50 per share for aggregate proceeds
of approximately $10.0 million. This issuance was exempt from registration
pursuant to Section 4(2) of the Securities Act.


    On August 5, 1999, BTI Ventures, L.L.C. an affiliate of KKR, purchased
13,333,334 shares of our series F preferred stock at a purchase price of $4.50
per share for aggregate proceeds of $60.0 million. On March 23, 2000, KKR
exercised its options to purchase an additional 5,263,158 shares of series F
preferred stock at $4.75 per share and 5,000,000 shares of series F preferred
stock at $5.00 per share. The transaction was funded and the associated shares
were issued on April 25, 2000. In connection with the private placement of the
series F preferred stock to BTI Ventures, L.L.C., which closed on August 5,
1999, and the related exercise of the KKR options, Lehman Brothers Inc. earned
compensation which included 646,316 shares of our series D preferred stock.
These issuances were exempt from registration pursuant to Section 4(2) of the
Securities Act.


                                      II-2
<PAGE>
    On August 5, 1999, in connection with the series F preferred stock offering,
we repurchased 2,222,222 shares of our Series C preferred stock for $10.0
million from a board member. This issuance was exempt from registration pursuant
to Section 4(2) of the Securities Act.

    On August 5, 1999, in connection with the series F preferred stock offering,
we converted each outstanding share of series B preferred stock into one share
of amended and restated series B preferred stock. The holders of series B
preferred stock, approximately 70 accredited investors, surrendered their
existing redemption and participating liquidation preference in exchange for
0.2222 shares of our series E preferred stock. These issuances were exempt from
registration pursuant to Section 4(2) of the Securities Act. We redeemed the
series E preferred stock for a total of $8.6 million.


    From February 10, 1998 to June 23, 2000, we granted stock options to
purchase up to 9,686,422 shares of our common stock pursuant to our stock option
plans, with a weighted average exercise price of $2.30 per share. These
issuances were exempt from registration pursuant to Rule 701 under the
Securities Act.


    In connection with our sale of $115,000,000 of 14% senior notes due 2008 to
qualified institutional buyers, in June 1998 we granted warrants to purchase up
to 2,530,473 shares of our common stock at an exercise price of $0.006 per
share. These issuances were exempt from registration pursuant to Section 4(2) of
the Securities Act.

    In March 2000, Mr. Jalkut, a member of our board of directors, agreed to
purchase 47,867 shares of our common stock for $200,000, and Mr. Ejabat, a
member of our board of directors, agreed to purchase 119,667 shares of our
common stock for $500,000.
