                          NEXTLINK COMMUNICATIONS, INC.
               NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1.  BASIS OF PRESENTATION

    The consolidated financial statements include the accounts of NEXTLINK
Communications, Inc., a Washington corporation, and its majority-owned
subsidiaries (collectively referred to as the Company). The Company, through
predecessor entities, was formed on September 16, 1994 and, through its
subsidiaries, provides competitive local telecommunications services in selected
markets in the United States. The Company is a majority-owned subsidiary of
Eagle River Investments, L.L.C. (Eagle River).

    The Company's financial statements include 100% of the assets, liabilities
and results of operations of subsidiaries in which the Company has a controlling
interest of greater than 50%. The Company's investment in Telecommunications of
Nevada, L.L.C. (Nevada L.L.C.), a limited liability company in which the Company
has a 40% interest and which operates a network that is managed by the Company
in Las Vegas, Nevada, is accounted for on the equity method. All operational
statistics of the Company included in this Report include 100% of the
operational statistics of Nevada L.L.C. Investments in entities in which the
Company has voting interests of not more than 20% are accounted for on the cost
method. All significant intercompany accounts and transactions have been
eliminated.

    The interim financial statements are unaudited and have been prepared
pursuant to the rules and regulations of the Securities and Exchange Commission.
Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted pursuant to such rules and regulations. These
condensed consolidated financial statements should be read in conjunction with
the audited consolidated financial statements and notes thereto included in the
Company's Form 10-KSB as filed with the Securities and Exchange Commission on
March 25, 1998.

    The financial information included herein reflects all adjustments
(consisting only of normal recurring adjustments) which are, in the opinion of
management, necessary to a fair presentation of the results for interim periods.
The results of operations for the three-month period ended March 31, 1998 are
not necessarily indicative of the results to be expected for the full year.

2.   FINANCINGS

    Debt

    On March 3, 1998, the Company completed the sale of $335.0 million in
aggregate principal amount of 9% Senior Notes due March 15, 2008. Proceeds from
the sale net of discounts, underwriting commissions, advisory fees and expenses
totaled approximately $326.5 million. The 9% Senior Notes are redeemable at the
option of the Company, in whole or in part, beginning March 15, 2003.

    The indenture pursuant to which the 9% Senior Notes are issued contains
certain covenants that, among other things, limits the ability of the Company
and its subsidiaries to incur additional indebtedness, issue stock in
subsidiaries, pay dividends or make other distributions, repurchase equity
interests or subordinated indebtedness, engage in sale and leaseback
transactions, create certain liens, enter into certain transactions with
affiliates, sell assets of the Company and its subsidiaries, and enter into
certain mergers and consolidations.

    In the event of a change in control of the Company as defined in the
indenture, holders of the 9% Senior Notes will have the right to require the
Company to purchase their 9% Senior Notes, in whole or in part, at a price equal
to 101% of the stated principal amount thereof, plus accrued and unpaid
interest, if any, thereon to the date of purchase. The 9% Senior Notes are
senior unsecured obligations of the Company, and are subordinated to all current
and future indebtedness of the Company's subsidiaries, including trade payables.



   8

    Redeemable Preferred Stock

    On March 31, 1998, the Company completed the sale of 4,000,000 shares of
6 1/2% cumulative convertible preferred stock (6 1/2% Preferred Stock) with a
liquidation preference of $50 per share. The sale generated gross proceeds to
the Company of $200.0 million, and proceeds net of underwriting discounts,
advisory fees and expenses of $193.9 million. Each share of 6 1/2% Preferred
Stock is convertible, at the option of the holder, into 1.145 shares of the
Company's Class A common stock (subject to customary adjustments). The Company
may cause such conversion rights to expire if the closing price of the Class A
common stock exceeds 120% of an implied conversion price (as defined) for 20
days in a 30 consecutive day trading period after April 15, 2001 and through
April 15, 2006. Dividends on the 6 1/2% Preferred Stock accrue from March 31,
1998 and are payable in cash quarterly, beginning on June 30, 1998, at an 
annual rate of 6 1/2% of the liquidation preference thereof. The Company is 
required to redeem all of the 6 1/2% Preferred Stock outstanding on March 31, 
2010 at a redemption price equal to 100% of the liquidation preference thereof,
plus accumulated and unpaid dividends to the date of redemption.

3.  NETWORK LEASE

    In February 1998, the Company entered into a 20-year capital lease for
exclusive rights to multiple fibers and innerducts throughout New York, New
Jersey, Connecticut, Pennsylvania, Delaware, Maryland and Washington D.C. The
Company paid $92.0 million in the transaction, of which $80.3 million was placed
into escrow pending completion and delivery of segments of the network route to
the Company. The payment was recorded as a long-term asset, and will be
reclassified as property and equipment as portions of the network are completed.
The Company has the option to renew the lease for two additional 10-year terms.

4.  JOINT VENTURE

    In January 1998, the Company and Nextel Communications, Inc. (Nextel), a
nationwide provider of wireless telephone services, formed a joint venture
called NEXTBAND Communications, L.L.C. (NEXTBAND), which is owned 50% each by
the Company and Nextel. NEXTBAND was the successful bidder in 42 markets
covering approximately 105 million POPs, or persons located within the licensed
areas owned, in the FCC's recently concluded local multipoint distribution
service (LMDS) auctions. NEXTBAND's total bid in the LMDS auctions was $134.7
million. NEXTLINK and Nextel have each contributed $25.0 million to fund the
license payment, and the balance is expected to be payable in the second
quarter of 1998. NEXTLINK and Nextel are developing a strategy to implement LMDS
technology as a cost-effective enhancement to their respective businesses.

5.  RECLASSIFICATIONS

    Certain reclassifications have been made to prior period amounts in order to
conform to the current presentation.

6.  SUBSEQUENT EVENT

    On April 1, 1998, the Company completed the sale of 9.45% Senior Discount
Notes (9.45% Notes), due April 15, 2008. The 9.45% Notes were issued at a
discount from their principal amount to generate aggregate gross proceeds to the
Company of approximately $400.0 million. Proceeds net of underwriting
commissions, advisory fees and expenses totaled $390.9 million. The 9.45% Notes
will accrete at a rate of 9.45% compounded semi-annually, to an aggregate
principal amount of approximately $637.0 million by April 15, 2003. No cash
interest will accrue on the 9.45% Notes until April 15, 2003. Interest will
become payable in cash semi-annually beginning on October 15, 2003. The 9.45%
Notes are redeemable at the option of the Company, in whole or in part, at any
time after April 15, 2003.

    The indenture pursuant to which the 9.45% Notes are issued contains certain
covenants that, among other things, limits the ability of the Company and its
subsidiaries to incur additional indebtedness, issue stock in subsidiaries, pay
dividends or make other distributions, repurchase equity interests or
subordinated indebtedness, engage in sale and leaseback transactions, create
certain liens, enter into certain transactions with affiliates, sell assets of
the Company and its subsidiaries, and enter into certain mergers and
consolidations.



   9

    In the event of a change in control of the Company as defined in the
indenture, holders of the 9.45% Notes will have the right to require the Company
to purchase their 9.45% Notes, in whole or in part, at a price equal to 101% of
the accreted value thereof, plus accrued and unpaid interest, if any, thereon to
the date of purchase. The 9.45% Notes are senior unsecured obligations of the
Company, and are subordinated to all current and future indebtedness of the
Company's subsidiaries, including trade payables.

PART I.      FINANCIAL INFORMATION

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations
     
OVERVIEW

    Since its inception in 1994, the Company has executed a strategy of
constructing and acquiring fiber optic networks and acquiring related
telecommunications businesses. Over this period, the Company has pursued this
strategy by constructing, acquiring, leasing fibers or capacity on, and entering
into agreements to acquire local telecommunications networks.

    The Company's primary focus is providing switched local and long distance
and enhanced communications services to small and medium sized commercial
end-user customers. The Company plans to acquire, build or develop networks in
new areas, expand its current networks, and also explore the acquisition or
licensing of additional enhanced communications services and other
telecommunications service providers. These efforts should allow the Company to
increase its presence in the marketplace, and facilitate providing a single
source solution for the telecommunications needs of its customers.

    The Company currently operates 16 facilities-based networks providing
switched local and long distance services in 26 markets in eight states. The
Company anticipates developing additional new markets during 1998 which,
together with its existing markets, are expected to have a total of
approximately 15 million addressable business lines by the end of 1998. The
Company's goal is to add or expand markets to increase its addressable business
lines for markets in service or under development to approximately 21 million by
the end of 1999.

    The table below provides selected key financial and operating data (dollars
are in thousands):

 (1)    EBITDA represents net loss before interest expense, interest income,
        depreciation, amortization and deferred compensation expense. EBITDA 
        is commonly used to analyze companies on the basis of operating 
        performance, leverage and liquidity. While EBITDA should not be 
        construed as a substitute for operating income or a better measure of
        liquidity than cash flow from operating activities, which are determined
        in accordance with generally accepted accounting principles, it is
        included herein to provide additional information with respect to the
        ability of the Company to meet future debt service, capital expenditure
        and working capital requirements.
 (2)    The operating data includes 100% of the statistics of the Las Vegas
        network, which the Company manages and in which the Company has a 40%
        membership interest.
 (3)    Route miles refers to the number of miles of the telecommunications path
        in which the Company-owned or leased fiber optic cables are installed.
 (4)    Fiber miles refers to the number of route miles installed along a
        telecommunications path, multiplied by the Company's estimate of the
        number of fibers along that path.

 (5)    Represents buildings physically connected to the Company's networks,
        excluding those connected by unbundled incumbent local exchange carrier
        (ILEC) facilities.
 (6)    Represents buildings connected to the Company's networks through leased
        or unbundled ILEC facilities.
 (7)    Represents the number of access lines in service, including those lines
        that are provided through resale of Centrex services, for which the
        Company is billing services. Access lines in service as of March 31,
        1998 includes 1,811 access lines acquired with the Company's shared
        tenant services business.

    The Company builds its networks to encompass the significant business
concentrations in each area it serves, focusing on direct connections to
end-user locations and ILEC central offices. The Company employs a uniform
technology platform for each of its local exchange networks that is based on the
Nortel DMS 500 digital local and long distance combination switching platform
and associated distribution technology. As of March 31, 1998, the Company had 12
operational Nortel DMS 500 switches, including one switch in its NEXTLAB
facility, and currently plans to install three additional switches by the end of
the second quarter of 1998. NEXTLAB is a fully functional model of one of the
Company's networks, which serves as a testing facility for switch software and
the Company's products and services and will serve as the Company's network
operations control center.

    The Company also provides enhanced communications services including
interactive voice response (IVR) services, which provide an interface between
the Company's clients and their customers for a variety of applications.
Historically, the Company has derived a substantial portion of its revenues from
its IVR services. As local and long distance revenues are expected to grow more
rapidly than revenues from the Company's enhanced communications services, the
Company anticipates that, over the next five years, local and long distance
revenues will account for a significantly higher percentage of total revenues.

    The development of the Company's businesses and the construction,
acquisition and expansion of its networks require significant expenditures,
substantial portions of which are incurred before the realization of revenues.
These expenditures, together with the associated early operating expenses,
result in negative cash flow until an adequate customer base is established.
However, as the customer base grows, the Company expects that incremental
revenues can be generated with decreasing incremental operating expenses, which
may provide positive contributions to cash flow. The Company has made the
strategic decision to build high capacity networks with broad market coverage,
which initially increases its level of capital expenditures and operating
losses. The Company believes that over the long term this will enhance the
Company's financial performance by increasing the traffic flow over the
Company's networks. The Company has recently entered into leased dark fiber and
fiber capacity arrangements which allow the Company, by installing one or more
switches and related electronics, to enter a market prior to completing
construction of its own fiber optic network.


RESULTS OF OPERATIONS

    Revenue increased 164% to $26.5 million during the first quarter of 1998,
from $10.1 million in the same period in 1997. The increase was driven by 239%
growth in revenues from bundled local and long distance services and dedicated
services, as well as by the acquisitions of Start Technologies Corporation
(Start) and Chadwick Telecommunications Corporation (Chadwick) in the fourth
quarter of 1997. Revenues reported in the first quarter of 1998 included $21.3
million derived from local and long distance, competitive access, dedicated line
services and shared tenant services and $5.2 million derived from enhanced
communications services, primarily IVR. The Company's IVR revenue comprised 18%
and 30% of the Company's total revenues during the first quarter of 1998 and
1997, respectively. The revenues generated by this subsidiary have tended to
fluctuate from quarter to quarter, as the revenues are generally event driven
and seasonal in nature.

    The Company began offering switched local and long distance services in
seven of its markets in July 1996, and in 18 additional markets during 1997.
Most recently, the Company began offering such services in Chicago, Illinois in
February 1998. In addition, the Company has offered dedicated line services
since January 1995 and has resold Centrex access lines since April 1995. The
Company increased the number of customer access lines added during the quarter
from 19,187 in the fourth quarter of 1997 to 22,703 during the first quarter of
1998. As of March 31, 1998, the Company had 72,834 access lines in service,
compared to 11,256 as of March 31, 1997, and 50,131 as 



   13

of December 31, 1997. Revenues from the provision of such services are expected
to continue to increase as a component of total revenues over future periods.
Access lines in service includes those lines which are provided through resale
of Centrex services, the number of which is decreasing over time as the Company
converts those customers to its own network.

    Operating expenses consist of costs directly related to providing
facilities-based network and enhanced communications services and also include
salaries and benefits and related costs of operations and engineering personnel.
Operating expenses increased 148% in the first quarter of 1998 to $24.6 million,
an increase of $14.6 million over the first quarter of 1997. This increase was
attributed to increased network costs related to provisioning higher volumes of
local, long distance and enhanced communications services, an increase in
employees and an increase in other related costs primarily to expand the
Company's switched local and long distance service businesses in its existing
and planned markets. To a lesser extent, the acquisitions of Start and Chadwick
in the fourth quarter of 1997 also contributed to the increase in operating
costs over those in the first quarter of 1997.

    Selling, general and administrative (SG&A) expenses include salaries and
related personnel costs, facilities expenses, sales and marketing, systems
development costs, consulting and legal fees and equity in loss of affiliates.
SG&A increased 141% in the three month period ended March 31, 1998, as compared
to the corresponding period in 1997. The increase was due to the Company's
increase in employees, as well as other costs associated with the expansion of
the Company's switched local and long distance service businesses in its
existing and planned markets.

    Deferred compensation expense was recorded in connection with the Company's
Equity Option Plan until April 1997, and in connection with the Company's Stock
Option Plan, which replaced the Equity Option Plan, subsequent to April 1997.
The stock options granted under the Equity Option Plan were considered
compensatory and were accounted for on a basis similar to that for stock
appreciation rights. All options outstanding under the Equity Option Plan were
regranted under the new Plan with terms and conditions substantially the same as
under the Equity Option Plan. As such, the Company continues to record deferred
compensation expense for those compensatory stock options issued, as well as for
compensatory stock options issued subsequent to the Plan conversion date.
Compensation expense is recognized over the vesting periods based on the excess
of the fair value of the stock options at the date of grant over the exercise
price.

    Depreciation expense increased primarily due to placement in service of
additional telecommunications network assets, including switches, fiber optic
cable, network electronics and related equipment. Amortization of intangible
assets increased primarily as a result of the Start and Chadwick acquisitions in
the fourth quarter of 1997.

    Interest expense increased 109% in the first quarter of 1998 over the
comparable period in the prior year due to an increase in the Company's average
outstanding indebtedness over the respective periods, primarily relating to the
9 5/8% Senior Notes issued in October 1997. See "--Liquidity and Capital
Resources." Pursuant to Statement of Financial Accounting Standards No. 34, the
Company capitalizes a portion of its interest costs as part of the construction
cost of its communications networks. Capitalized interest during the first
quarter of 1998 totaled $0.5 million. Interest expense will increase in future
periods in conjunction with the sale of $335.0 million in aggregate principal
amount of 9% Senior Notes on March 3, 1998, and the 9.45% Senior Discount Notes
on April 1, 1998. Interest income results from investment of excess cash and
certain securities that have been pledged as collateral for interest payments on
the 12 1/2% Senior Notes. The 133% increase in interest income in the first
quarter of 1997 over the same period in 1996 corresponded to the increase in the
Company's average outstanding cash balances.


LIQUIDITY AND CAPITAL RESOURCES

    The competitive local telecommunications service business is a
capital-intensive business. The Company's existing operations have required and
will continue to require substantial capital investment for the acquisition and
installation of fiber, electronics and related equipment in order to provide
switched services in the Company's networks and the funding of operating losses
during the start-up phase of each market. In addition, the Company's strategic
plan calls for expansion into additional market areas. Such expansion will
require significant additional capital for: potential acquisitions of businesses
or assets; design, development and construction of new networks;



   14

and the funding of operating losses during the start-up phase of each market.
During the first three months of 1998, the Company used $24.2 million in cash
for operating activities, compared to $14.1 million for the same period in the
prior year. The increase was primarily due to a substantial increase in the
Company's activities associated with the continued development and expansion of
switched local and long distance service operations. During the first three
months of 1998, the Company invested an additional $44.5 million in property and
equipment. During the same period in 1997, the Company invested $17.6 million in
property and equipment, and $37.0 million in acquisitions of telecommunications
assets and businesses and equity investments in telecommunications businesses.

    In February 1998, the Company signed a definitive agreement with Metromedia
Fiber Network for exclusive rights to multiple fibers and innerducts for 20
years, with two 10-year renewals. The route covered by the agreement extends
from Manhattan to White Plains (NY), to Stamford (CT), to Newark (NJ) and south
from Manhattan through Philadelphia, Wilmington (DE), Baltimore, and to
Washington (DC). The route will offer frequent splice points within metropolitan
areas and on routes between metropolitan areas, as well as provide access to
ILEC central and tandem switching offices. The Company paid $92.0 million in
cash for this transaction, $80.3 million of which was placed into escrow, to be
released as segments of the route are constructed and delivered to the Company.

    In January 1998, the Company and Nextel Communications, Inc. (Nextel) formed
NEXTBAND, a joint venture that is owned 50% each by the Company and Nextel.
NEXTBAND was the successful bidder in 42 markets in the FCC's recently-concluded
local multipoint distribution service (LMDS) auctions. NEXTBAND's total bid in
the LMDS auctions was $134.7 million. NEXTLINK and Nextel have each contributed
$25.0 million to fund the license payment, and the balance is expected to be 
payable in the second quarter of 1998. The Company is in process of defining 
its operational and financial relationships with NEXTBAND and Nextel, as well 
as its plans for implementation of an LMDS strategy, which could involve 
substantial additional capital expenditures.

    On March 3, 1998, the Company completed the sale of $335.0 million in
aggregate principal amount of 9% Senior Notes due March 15, 2008. Proceeds from
the sale net of discounts, underwriting commissions, advisory fees and expenses
totaled approximately $326.5 million. Interest payments on the 9% Senior Notes
are due semi-annually, beginning September 1998.

    On March 31, 1998, the Company completed the sale of 4,000,000 shares of
6 1/2% cumulative convertible preferred stock (6 1/2% Preferred Stock) with a
liquidation preference of $50 per share. The sale generated gross proceeds to
the Company of $200.0 million, and proceeds net of underwriting discounts,
advisory fees and expenses of $193.9 million. Each share of 6 1/2% Preferred 
Stock is convertible, at the option of the holder, into 1.145 shares of the 
Company's Class A common stock (subject to customary adjustments). Dividends
on the 6 1/2% Preferred Stock accrue from March 31, 1998 and are payable 
quarterly in cash, beginning on June 30, 1998.

     On April 1, 1998, the Company completed the sale of 9.45% Senior Discount
Notes (9.45% Notes), due April 15, 2008. The 9.45% Notes were issued at a
discount from their principal amount to generate aggregate gross proceeds to the
Company of approximately $400.0 million. Proceeds net of underwriting
commissions, advisory fees and expenses totaled $390.9 million. The 9.45% Notes
will accrete at a rate of 9.45% compounded semi-annually, to an aggregate
principal amount of approximately $637.0 million by April 15, 2003. No cash
interest will accrue on the Notes until April 15, 2003. Interest will become
payable in cash semi-annually beginning on October 15, 2003.

    The Company will use the net proceeds from the sale of the 9% Senior Notes,
the 6 1/2% Preferred Stock and the 9.45% Notes and existing unrestricted cash
balances for expenditures relating to the development, construction, acquisition
and operation of telecommunications networks and service providers and the
offering of telecommunications services in those areas where the Company
currently operates or intends to operate. Expenditures for the construction and
operation of networks include (i) the purchase and installation of switches and
related electronics in existing networks and in networks to be constructed or
acquired in new or adjacent markets, (ii) the purchase and installation of fiber
optic cable and electronics to expand existing networks and develop new
networks, including the connection of new buildings, (iii) the development of
its comprehensive information technology platform, (iv) the acquisition of LMDS
spectrum purchased in the FCC's auction and the construction 



   15

and deployment of associated facilities and (v) the funding of operating losses
and working capital. The Company may also acquire or invest in businesses that
consist of existing networks or companies engaged in businesses similar to those
engaged in by the Company and its subsidiaries or other complementary
businesses.

    As of March 31, 1998, the Company had unrestricted cash and investments of
$1,070.7 million and $1,461.6 million on a pro forma basis after giving effect
to the April 1, 1998 sale of the 9.45% Notes. The Company's current plan
contemplates an aggressive expansion into a number of new markets. The Company
may pursue various alternatives for achieving its growth strategy, including:
additional network construction; additional leases of network capacity from
third party providers; acquisitions of existing networks; and spectrum that was
purchased during the LMDS auctions and associated facilities construction and
deployment. The Company also anticipates that a substantial amount of additional
capital expenditures will be made in 1999 and beyond. The funding of these
capital expenditures is expected to be provided by existing cash balances,
future vendor and/or credit facilities, future public or private sales of debt
securities, future sales of public or private capital stock and joint ventures.
There can be no assurance, however, that the Company will be successful in
raising sufficient additional capital on terms that it will consider acceptable
or that the Company's operations will produce positive consolidated cash flow in
sufficient amounts to meet its interest and dividend obligations on its
outstanding securities. Failure to raise and generate sufficient funds may
require the Company to delay or abandon some of its planned future expansion or
expenditures, which could have a material adverse effect on the Company's growth
and its ability to compete in the telecommunications services industry.

    In addition, the Company's operating flexibility with respect to certain
business matters is, and will continue to be, limited by covenants associated
with the 12 1/2% Senior Notes, the 9 5/8% Senior Notes, the 9% Senior Notes and
the 9.45% Notes (collectively referred to as the Senior Notes). Among other
things, these covenants limit the ability of the Company and its subsidiaries to
incur additional indebtedness, create liens upon assets, apply the proceeds from
the disposal of assets, make dividend payments and other distributions on
capital stock and redeem capital stock. In addition, the terms of the 14% Senior
Exchangeable Redeemable Preferred Shares and 6 1/2% Preferred Stock
(collectively referred to as the Preferred Shares) contain certain covenants
that may limit the Company's operating flexibility with respect to the
incurrence of indebtedness and/or issuance of additional preferred shares. There
can be no assurance that such covenants will not adversely affect the Company's
ability to finance its future operations or capital needs or to engage in other
business activities that may be in the interest of the Company. The Company was
in compliance with all covenants associated with the Senior Notes and Preferred
Shares as of March 31, 1998.


INFORMATION REGARDING FORWARD LOOKING STATEMENTS

    The statements contained in this report and in associated prior filings by
the Company with the Securities and Exchange Commission which are not historical
facts are "forward-looking statements" (as such term is defined in the Private
Securities Litigation Reform Act of 1995), which can be identified by the use of
forward-looking terminology such as "believes", "expects", "may", "will",
"should", or "anticipates" or the negative thereof or other variations thereon
or comparable terminology, or by discussions of strategy that involve risks and
uncertainties. Such forward-looking statements include: the Company's plans to
build and acquire networks and offer services in new areas, expand its current
networks and explore the acquisition or licensing of additional enhanced
communications services and other telecommunications service providers; the
Company's presence in the marketplace and its ability to provide a single source
solution for the telecommunications needs of its customers; the Company's
anticipated development of new markets; its expected number of addressable
business lines by the end of 1998 and 1999; its plans to install additional
switches by the end of the second quarter of 1998; its anticipation regarding
the percentage of revenues accounted for by local and long distance services;
its expectation regarding incremental revenues, incremental operating expenses
and contributions to cash flow; the Company's belief regarding its financial
performance and traffic flow over its networks; its use of proceeds from various
financings; its anticipated capital expenditures; and other statements contained
herein regarding matters that are not historical facts. Management wishes to
caution the reader that these forward-looking statements are only predictions.
These statements are based on a number of assumptions that ultimately could
prove inaccurate and, therefore, no assurance can be given that the future
results will be achieved. Actual events or results may differ materially as a
result of a 



   16

number of factors, including those identified in the Company's annual report on
Form 10-KSB (File No. 333-04603). Factors that could affect performance include:
the level of the Company's future negative cash flows and operating losses
incurred by the Company until it establishes an adequate revenue base and
generates substantial revenues from the provision of switched local and long
distance services; successfully generating or raising on terms that the Company
will consider acceptable sufficient capital to accommodate planned future
expansion and expenditures; continued attraction and retention of qualified
managerial, professional and technical personnel; timely installation of the
required switches, fiber optic cable and associated electronics necessary to
provide switched local service in a manner that will permit the resolution of
technical problems; successfully negotiating new and, to the extent necessary,
renegotiating existing interconnection agreements; successfully developing
effective systems relating to ordering, provisioning and billing for
telecommunications services; successfully offering, marketing and selling
switched local services and other enhanced products and services in all of the
Company's networks as quickly as practicable; sufficient access to the ILEC's
networks and adequate cooperation therefrom to connect new customers to the
Company's network on a timely basis; identifying, financing and completing
suitable acquisitions; maintaining existing, and obtaining and maintaining new,
franchises, permits and rights-of-way and any required governmental
authorizations, franchises and permits on a timely basis; competition from
incumbent providers and new entrants; the nature of regulatory, legislative and
judicial developments; and rapid and significant changes in technology. These
are representative of factors that could affect the outcome of the
forward-looking statements. In addition, such statements could be affected by
general industry and market conditions and economic conditions including
interest rate fluctuations.

NEW ACCOUNTING STANDARD

        On April 9, 1998, the AICPA released Statement of Position 98-5,
"Reporting on the Costs of Start-Up Activities" (SOP 98-5). The new standard
requires that all entities expense costs of start-up activities as those costs
are incurred. SOP 98-5 defines "start-up costs" as those costs directly related
to pre-operating, pre-opening, and organization activities. This standard must
be adopted in fiscal years beginning after December 15, 1998. The Company does
not capitalize start-up costs as defined by SOP 98-5; as such, adoption of SOP
98-5 will not have a material impact on the Company's financial position.

PART II.       OTHER INFORMATION

Item 1.    Legal Proceedings

             The Company is not currently a party to any legal proceedings,
             other than regulatory and other proceedings that are in the normal
             course of its business.

Item 2.    Changes in Securities and Use of Proceeds

             On March 31, 1998, the Company issued and sold 4,000,000 shares of
             6 1/2% cumulative convertible preferred stock (6 1/2% Preferred
             Stock) with a liquidation preference of $50 per share. Of the 
             total shares sold, 3,980,000 were issued in reliance upon an 
             exemption from registration contained in Section 4(2) of the 
             Securities Act of 1933, as amended (the Act), and 20,000 shares 
             were sold outside of the United States pursuant to Regulation S 
             of the Act. The sale generated gross proceeds to the Company of 
             $200.0 million, and proceeds net of underwriting discounts, 
             advisory fees and expenses were $193.9 million. The initial 
             purchases of the 6 1/2% Preferred Stock were Solomon Smith Barney 
             and Goldman, Sachs & Co. Each share of 6 1/2% Preferred Stock is 
             convertible, at the option of the holder, into 1.145 shares of the
             Company's Class A common stock (subject to customary adjustments).
             The Company may cause such conversion rights to expire if the 
             closing price of the Class A common stock exceeds 120% of an 
             implied conversion price (as defined) for 20 days in a 30 
             consecutive day trading period after April 15, 2001 and through 
             April 15, 2006. The Company is required to redeem all of the 
             6 1/2% Preferred Stock outstanding on March 31, 2010 at a 
             redemption price equal to 100% of the liquidation preference 
             thereof, plus accumulated and unpaid dividends to the date of 
             redemption.

             The Company filed a registration statement on Form S-1 (File No.
             333-32001) which became effective on September 26, 1997, whereby
             15,200,000 shares of Class A common stock, $.02 par value per
             share, were sold in an initial public offering at a price of $17
             per share. Of the 15,200,000 shares of Class A common stock sold,
             12,000,000 were sold by the Company and 3,200,000 were sold by a
             selling shareholder. The Company did not receive any of the
             proceeds from the sale of shares by the selling shareholder. In
             addition, the underwriters of the IPO, led by Salomon Brothers Inc,
             exercised an option to purchase 2,280,000 additional shares of
             Class A common stock at the same price per share. Net proceeds to
             the Company from the initial public offering totaled approximately
             $226.8 million, after deducting underwriting discounts, advisory
             fees and expenses aggregating approximately $16.0 million. The
             Company intends to use substantially all of the net proceeds from
             the initial public offering for expenditures relating to the
             expansion of existing networks and services, the development and
             acquisition of new networks and services and the funding of
             operating losses and working capital. Approximately $65.0 million
             of the total proceeds from this offering had been used as of March
             31, 1998, $44.5 million of which was used for the purchase of
             property and equipment, and the remainder for the network lease
             agreement entered into in February 1998.

             The Company filed a registration statement on Form S-1 (File No.
             333-32003) which became effective on September 26, 1997, whereby
             the Company sold $400.0 million aggregate principal amount of 9
             5/8% Senior Notes. The offering was led by Salomon Brothers Inc.
             Net proceeds from the sale of the 9 5/8% Senior Notes totaled
             approximately $388.5 million, after deducting issuance costs
             aggregating approximately $11.5 million, relating to underwriting
             discounts, advisory fees and expenses. The use of proceeds from the
             debt offering are substantially the same as the Company's initial
             public offering. None of the proceeds from this offering had been
             used as of March 31, 1998.
