     THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME ON
               , 1997 UNLESS EXTENDED.
 
     Brooks Fiber Properties, Inc., a Delaware corporation (the "Company"), is
hereby offering (the "Exchange Offer"), upon the terms and subject to the
conditions set forth in this Prospectus and the accompanying Letter of
Transmittal (the "Letter of Transmittal"), to exchange $1,000 principal amount
of its 11 7/8% Senior Discount Notes due November 1, 2006 (the "Exchange
Notes"), which exchange has been registered under the Securities Act of 1933, as
amended (the "Securities Act"), pursuant to a registration statement of which
this Prospectus is a part (the "Registration Statement"), for each $1,000
principal amount of its outstanding 11 7/8% Senior Discount Notes due November
1, 2006 (the "Private Notes"), of which $400,000,000 in aggregate principal
amount was issued on November 7, 1996 and is outstanding as of the date hereof.
The form and terms of the Exchange Notes are identical in all material respects
to those of the Private Notes, except for certain transfer restrictions and
registration rights relating to the Private Notes and except for certain
interest provisions related to such registration rights. The Exchange Notes will
evidence the same indebtedness as the Private Notes (which they replace) and
will be entitled to the benefits of an Indenture dated as of November 7, 1996
governing the Private Notes and the Exchange Notes (the "Indenture"). The
Private Notes and the Exchange Notes are sometimes referred to herein
collectively as the "Notes." See "The Exchange Offer" and "Description of the
Notes."
 
     The Exchange Notes will be redeemable at the option of the Company, in
whole or in part, at any time on or after November 1, 2001 at the redemption
prices set forth herein plus accrued and unpaid interest, if any, to the date of
redemption. In the event of a Strategic Equity Investment on or before November
1, 1999, up to a maximum of 33 1/3% of the aggregate principal amount of the
Notes originally issued will, at the option of the Company, be redeemable from
the net cash proceeds of such Strategic Equity Investment at a redemption price
equal to 111.875% of the Accreted Value thereof. See "Description of the Notes
- -- Optional Redemption." In the event of a Change of Control, holders of the
Exchange Notes will have the right to require the Company to purchase their
Exchange Notes, in whole or in part, at a price equal to 101% of their Accreted
Value on or before November 1, 2001 or 101% of their stated principal amount,
plus accrued and unpaid interest, if any, thereon to the date of purchase, after
November 1, 2001. See "Description of the Notes -- Covenants -- Change of
Control."
 
     The Exchange Notes will be senior unsecured obligations of the Company,
will rank pari passu in right of payment with the Private Notes and all other
existing and future senior unsecured obligations of the Company and will rank
senior in right of payment to any future subordinated obligations of the
Company. The Notes will be effectively subordinated to all obligations,
including trade payables, of the Company's subsidiaries. As of September 30,
1996, on a pro forma basis after giving effect to the offering of the Private
Notes (the "Private Note Offering") and the issuance of $50 million aggregate
principal amount of secured indebtedness on November 12, 1996, (i) the total
amount of outstanding liabilities of the Company (parent only), including trade
payables, would have been approximately $546.8 million, of which $50 million
would have been secured obligations, and (ii) the total amount of outstanding
liabilities of the Company's subsidiaries, including trade payables, would have
been $14.1 million, of which $0.1 million would have represented secured
obligations. See "Description of Other Credit Facilities."
 
     The Company will accept for exchange any and all validly tendered Private
Notes not withdrawn prior to 5:00 p.m., New York City time, on                ,
1997, unless the Exchange Offer is extended by the Company in its sole
discretion (the "Expiration Date"). Tenders of Private Notes may be withdrawn at
any time prior to the Expiration Date. Private Notes may be tendered only in
integral multiples of $1,000. The Exchange Offer is subject to certain customary
conditions. See "The Exchange Offer."

                              NOTICE TO INVESTORS
 
     Based on interpretations by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes that the Exchange Notes issued pursuant to the
Exchange Offer in exchange for Private Notes may be offered for resale, resold
and otherwise transferred by a holder thereof without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that the holder is acquiring the Exchange Notes in the ordinary course of its
business, is not participating and has no arrangement or understanding with any
person to participate in the distribution of the Exchange Notes and is not an
"affiliate" of the Company within the meaning of Rule 405 of the Securities Act.
Holders of Private Notes wishing to accept the Exchange Offer must represent to
the Company that such conditions have been met. Each broker-dealer who holds
Private Notes acquired for its own account as a result of market-making or other
trading activities and who receives Exchange Notes for its own account in
exchange for such Private Notes pursuant to the Exchange Offer must acknowledge
that it will deliver a prospectus in connection with any resale of such Exchange
Notes. The Company believes that none of the registered holders of the Private
Notes is an "affiliate" as such term is defined in Rule 405 under the Securities
Act) of the Company.
 
     This Prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of Exchange Notes
received in exchange for Private Notes acquired by such broker-dealer as a
result of market-making or other trading activities. The Letter of Transmittal
states that by acknowledging that it will deliver a prospectus in connection
with any resale of such Exchange Notes, and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. The Company has agreed to make this Prospectus
(as it may be amended or supplemented) available to any such broker-dealer that
requests copies of such Prospectus in the Letter of Transmittal for use in
connection with any such resale for a period of up to 90 days after the
Expiration Date. See "Plan of Distribution."
 
     Prior to the Exchange Offer, there has been no public market for the
Exchange Notes. There can be no assurance as to the liquidity of any markets
that may develop for the Exchange Notes, the ability of holders to sell the
Exchange Notes, or the price at which holders would be able to sell the Exchange
Notes. The Company does not intend to apply for listing of the Exchange Notes
for trading on any securities exchange or for inclusion of the Exchange Notes in
any automated quotation system. The National Association of Securities Dealers,
Inc. ("NASD") has designated the Private Notes as securities eligible for
trading in the Private Offerings, Resales and Trading through Automatic Linkages
("PORTAL") market of the NASD (see "Price Range of the Private Notes") and the
Company has been advised that Goldman, Sachs & Co. and Salomon Brothers Inc have
heretofore acted as market makers for the Private Notes. The Company has been
advised by each of the aforesaid market makers that it currently intends to make
a market in the Exchange Notes. Future trading prices of the Exchange Notes will
depend on many factors, including among other things, prevailing interest rates,
the Company's operating results and the market for similar securities.
Historically, the market for securities similar to the Exchange Notes, including
non-investment grade debt, has been subject to disruptions that have caused
substantial volatility in the prices of such securities. There can be no
assurance that any market for the Exchange Notes, if such market develops, will
not be subject to similar disruptions. See "Risk Factors -- No Prior Public
Market for Exchange Notes; Possible Volatility of Market Price of Exchange
Notes."
 
     The Company will not receive any proceeds from, and has agreed to bear the
expenses of, the Exchange Offer. No underwriter is being used in connection with
the Exchange Offer.
 
     THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT
SURRENDERS FOR EXCHANGE FROM, HOLDERS OF PRIVATE NOTES IN ANY JURISDICTION IN
WHICH THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE IN COMPLIANCE
WITH THE SECURITIES OR BLUE SKY LAWS OF SUCH JURISDICTION.

                               PROSPECTUS SUMMARY
 
     The following is a summary of certain information contained elsewhere in
this Prospectus. Reference is made to, and this Summary is qualified in its
entirety by, the more detailed information, including the Company's consolidated
financial statements and notes thereto, contained herein. Unless otherwise
noted, references to the "Company" are to Brooks Fiber Properties, Inc., a
Delaware corporation, and its consolidated subsidiaries. Capitalized terms used
in this Prospectus which are not otherwise defined herein have the respective
meanings ascribed to them in the Glossary included as Annex A hereto.
 
                                  THE COMPANY
 
     The Company is a leading full service provider of competitive local
telecommunications services, commonly referred to as a competitive local
exchange carrier ("CLEC"), in selected markets within the United States (see
"The Competitive Local Telecommunications Services Industry"). The Company
acquires and constructs its own state-of-the-art fiber optic networks and
facilities and leases network capacity from others to provide long distance
carriers ("IXCs"), Internet Service Providers ("ISPs"), wireless carriers and
business, government and institutional end users with an alternative to the
incumbent local exchange companies (the "ILECs") for a broad array of high
quality voice, data, video transport and other telecommunications services.
 
     The Company has completed the first year of its entry into the fully
competitive switched services or local exchange market. The initial performance
from the Company's entry into switched services has yielded results, both in
terms of lines connected and revenues received, that are substantially in excess
of the Company's expectations. As a result, the Company has revised its capital
deployment plans to allow for an increased level of demand-driven capital
spending necessary to take full advantage of the opportunities presented in the
switched services portion of the marketplace. The Company has revised its
network development plans to (i) increase the geographic reach and robustness of
its networks to allow the Company to serve a significantly higher percentage of
the market by extending its networks to serve most, if not all, of the ILECs'
central offices in its markets and (ii) more rapidly deploy switches with full
capabilities for local dial tone and switched access termination and origination
services. Through its equity and debt financings to date, the Company has raised
approximately $800 million to fund the Company's acquisition and development of
its initial 30 networks, including funds necessary for the expansion of such
networks in accordance with the Company's capital deployment plans described
above. The Company intends to use the net proceeds from the Depositary Shares
Offering (see "Financing Plan -- Equity Capital" below), along with additional
financing to be obtained in the future, to fund the Company's expansion from 30
to 40 networks by the end of 1997. See "Financing Plan" below.
 
     The Company currently has systems in 30 cities, consisting of systems in
operation in 22 cities and under construction in eight cities. The Company's
networks under construction are all expected to become operational by the end of
the second quarter of 1997. Networks are considered operational when they are
able to begin providing services to customers. The Company's networks are
located in three regions -- the Eastern Region, Central Region and Western
Region. See "Business of the Company -- Cities Served." The Company specifically
targets second and third tier markets (those with populations ranging from
250,000 to two million) with attractive demographic, economic, competitive and
telecommunications demand characteristics. The Company's networks are generally
designed to access at least 70% to 80% of the identified business, government
and institutional end user revenue base and the IXC facilities ("Points of
Presence" or "POPs") and substantially all of the central offices of the ILECs
within their markets. In accordance with the pro-competitive provisions of the
Telecommunications Act of 1996, the Company has established interconnection
agreements with ILECs for 26 of its 30 networks. The Company is also certified
as a CLEC in 26 of its 30 networks. At November 30, 1996, the Company had a
total of 20 digital telephone switches installed in its networks. Switches have
been deployed to serve substantially all of the Company's operating networks.
The Company has increased the number of networks
 
                                        3
<PAGE>   6
 
in operation or under construction from 11 at December 31, 1994 to 30 at
present. At November 30, 1996, the Company had a total of 931 route miles of
optical fiber cable installed, 454,815 voice grade equivalent (VGE) circuits in
service, 17,914 CLEC lines installed and 831 on-net and 1,273 off-net buildings
connected.
 
     The Company plans to have systems in operation or under construction in a
total of 40 cities by the end of 1997 and 50 cities by the end of 1998. The
Company expects its expansion into additional cities will be accomplished by the
acquisition of existing networks as well as the construction of new networks.
For a discussion of the steps the Company takes in acquiring and developing new
networks, see "Business of the Company -- Network Acquisition, Development and
Design" and "-- Network Construction." See also "Risk Factors -- Significant
Future Capital Requirements; Substantial Indebtedness," "-- Risks Associated
with Implementation of Growth Strategy" and "-- Risks Associated with Possible
Acquisitions."
 
     The Company believes that there are attractive return opportunities for
CLECs in second and third tier markets due to the combination of (i) continuing
pro-competitive regulatory changes that have increased the addressable market
for CLEC services and (ii) the competitive dynamics which, until 1994, focused
CLEC network development primarily in larger markets. See "Business of the
Company -- CLEC Market Potential," "The Competitive Local Telecommunications
Services Industry" and "Regulatory Overview."
 
     The Company's current annualized revenues, based on September 1996
revenues, are $60.1 million, as compared with total revenues in 1995 of $14.2
million ($23.1 million on a pro forma basis giving effect to the acquisition of
Brooks Telecommunications Corporation ("BTC") on January 2, 1996 and the
acquisition of City Signal, Inc. (the "City Signal Acquisition") on January 31,
1996) and total revenues of $2.8 million in 1994, the Company's first full year
of operation. Since inception, the Company's operations have resulted in
earnings (losses) before minority interests, interest, taxes, depreciation and
amortization (EBITDA) of ($204,000) for the period from November 10, 1993
through December 31, 1993, ($2.7) million for the year ended December 31, 1994,
($4.4) million for the year ended December 31, 1995 and ($9.9) million for the
nine months ended September 30, 1996. As of September 30, 1996, the Company had
an accumulated deficit of $40.4 million. As of September 30, 1996, on a pro
forma adjusted basis giving effect to (i) the receipt of $217.2 million pursuant
to the Company's Private Note Offering, (ii) the exchange of minority interests
in the Company's subsidiaries for an aggregate of 1,192,980 shares of Common
Stock since September 30, 1996 and (iii) the receipt of $7.7 million upon
exercises of warrants and options to purchase an aggregate of 1,427,269 shares
of Common Stock since September 30, 1996, the Company had cash, cash equivalents
and marketable securities of $554.5 million, total assets of $870.2 million,
long-term debt of $539.5 million and paid-in capital of $349.6 million. See
"Capitalization."
 
     Initially, the Company's revenues were derived primarily from end user to
end user private line connections and from a variety of access services
including: (i) access between IXCs, (ii) access between end users and IXCs,
(iii) collocated special access and (iv) collocated POP to ILEC switched access
transport. The Company is expanding its revenue base by entering new markets, by
continuing to develop and add to its existing systems and by continuing to add
capabilities to offer switched services and local dial tone, centrex, switched
access origination and termination services and desktop products. The Company is
also adding capabilities to provide other enhanced services, such as high speed
video conferencing, frame relay, ATM-based packet transport services and
Internet access products, in all of its operating networks by the end of 1997.
See "Business of the Company -- Current Products and Services" and "-- Planned
Products and Services."
 
     The Company has assembled an experienced management, sales and operations
team with extensive experience and strong contacts within the telecommunications
industry. See "Management."

                             CLEC MARKET POTENTIAL
 
     Industry sources have estimated that the 1995 aggregate revenues of all
ILECs approximated $102 billion of which approximately $89 billion was derived
from switched services. Initially, CLECs were able to compete for only the
non-switched special access/private line services portion of this market (which
accounted for an estimated $8.6 billion of ILEC revenues in 1995). Accordingly,
the development of competitive networks occurred initially in larger
metropolitan areas that have proportionately greater revenue potential for this
limited portion of the local exchange market. However, since February 1994, as a
result of actions by the FCC requiring ILECs to allow CLECs to connect their
networks to the ILECs' networks (the "Interconnection Decisions"), CLECs have
also been permitted to compete for the collocated special access and switched
access transport/termination services portion of this market (which together
accounted for an estimated $13.8 billion of ILEC revenues in 1995). This has
enhanced the opportunities for the development of competitive networks in second
and third tier cities, which constitute a significant portion of the local
exchange market. In addition, most states have taken regulatory and legislative
action to open their markets to local exchange competition. The Company expects
that continuing pro-competitive regulatory changes, including those mandated by
the Telecommunications Act of 1996, together with increasing customer demand,
will create more opportunities to introduce additional services, expand the
Company's networks and address a larger customer base. The Company also expects
that access revenues from IXCs will increase as the IXCs move their access
business away from the ILECs (which are seeking the regulatory approvals
necessary to compete with the IXCs in providing long distance service) to
competitive providers of local telecommunications services. On October 15, 1996,
the United States Court of Appeals for the Eighth Circuit issued a partial stay,
pending a hearing on the merits, of FCC rules that had been scheduled to come
into effect on October 1, 1996 that set forth the amounts that ILECs can charge
CLECs and other telecommunications providers for access to the ILEC's networks.
However, in this ruling, which applies solely to pricing issues and the
so-called "pick and choose" rules, the Court did not stay the effectiveness of
the FCC rules requiring interconnection. As a result, the stay is not expected
to have any material effect on the Company's existing interconnection agreements
with ILECs or the pricing provisions thereof. See "Regulatory Overview --
Federal Regulation."
 
                               CORPORATE STRATEGY
 
     The Company's goal is to become the primary full service provider of
competitive local telecommunications services to IXCs, ISPs, wireless carriers
and business, government and institutional end users in selected cities by
offering superior products with excellent customer service at prices below those
charged by the ILECs. The principal elements of the Company's strategy include:
 
          TARGET SECOND AND THIRD TIER MARKETS. The Company believes that
     continuing pro-competitive regulatory changes and the broadening range of
     services that can be offered by CLECs present attractive opportunities for
     new CLEC entrants in second and third tier markets where there are
     typically fewer CLEC competitors than in first tier markets and where the
     ILECs generally have placed a lower priority on installing fiber optic
     systems comparable to those being installed by the Company. As an early
     entrant in selected second and third tier markets, the Company believes it
     can attain a leadership position by securing needed franchises and
     rights-of-way, installing robust state-of-the-art CLEC networks and
     facilities (i.e., networks which are capable of reaching at least 70% to
     80% of identified business end-users in the market and most, if not all, of
     the ILEC's central offices) and establishing customer relationships with
     IXCs, ISPs, wireless carriers and business, government and institutional
     end users that will enable it to take advantage of the attractive potential
     growth rates for local exchange service revenues in those markets.
 
          AGGRESSIVELY PURSUE SWITCHED SERVICES OPPORTUNITY. The
     Telecommunications Act of 1996 mandates that ILECs throughout the U.S.
     enter into arrangements with competitors such as the Company for central
     office collocation and unbundling of local services. The Company believes
 
                                        5
<PAGE>   8
 
     that implementation of these and other pro-competitive policies creates
     favorable opportunities to pursue more aggressively the provision of local
     switched services. The Company has a total of 20 digital telephone switches
     installed in its operating networks and plans to leverage its networks and
     customer relationships by offering local dial tone, switched access
     termination and origination services, centrex and desktop products. The
     Company currently offers such services and products in substantially all of
     its operating networks and expects to offer such services and products in
     all of its operating networks by the end of the second quarter of 1997. The
     Company has increased the number of CLEC lines in service from 3,187 at
     December 31, 1995 (on a pro forma basis giving effect to the City Signal
     Acquisition) to 17,914 at November 30, 1996, with annualized CLEC revenues
     increasing from $2.5 million based on December 1995 revenues to $10.2
     million based on September 1996 revenues. See "Business of the Company --
     Current Products and Services."
 
          EXPAND ENHANCED SERVICE OFFERINGS. Consistent with its strategy of
     aggressively pursuing switched services opportunities, the Company is
     expanding its capabilities to provide flexible, enhanced services that
     complement its switch-based services. Such enhanced services include, among
     others, high speed video conferencing, frame relay and ATM-based packet
     transport services and Internet access products. The Company is currently
     offering such services in certain markets and expects to offer such
     services in all of its operating networks by the end of 1997. The Company
     also plans to continue to upgrade and add to its systems and services as
     technology and regulations permit. See "Business of the Company -- Planned
     Products and Services."
 
          CONTINUE TO BUILD OUT EXISTING SYSTEMS. The Company strives to build a
     sufficient revenue base in each of its systems to generate the cash flow
     necessary to enable it to devote more resources to developing and expanding
     its systems as opposed to funding initial operating losses. As a result of
     favorable regulatory developments and the Company's initial favorable
     experiences with the provision of local switched services, the Company has
     determined to more rapidly develop and expand its systems. Its plans
     include increasing the number of cities served, expansion of its existing
     networks and accelerating the deployment of switches and ILEC central
     office collocations. The Company believes that its access to significant
     capital and technical resources and its ongoing efforts to develop close
     working relationships with its IXC customers (see "--Build on strategic
     relationships" below) will enable it to more rapidly develop and expand its
     systems, add to its service offerings and establish the strong customer
     relationships necessary to solidify its competitive position in its
     selected markets.
 
          CONTINUE TO INCREASE THE NUMBER OF CITIES SERVED. The Company recently
     achieved its long-held strategic objective of having systems in operation
     or under construction in a total of 30 cities by the end of 1996. The
     Company plans to have systems in operation or under construction in a total
     of 40 cities by the end of 1997 and a total of 50 cities by the end of
     1998. The Company's expansion into additional cities is expected to be
     accomplished by the acquisition of existing networks as well as the
     development of new networks. See "Business of the Company -- Network
     Acquisition, Development and Design" and "-- Network Construction." By
     adding networks, the Company believes it can increase revenues and obtain
     economies of scale in its operating costs.
 
          BUILD ON STRATEGIC RELATIONSHIPS. In order to capitalize on the
     competitive dynamics of the changing IXC/ILEC relationships, the Company
     has established close business alliances with major IXCs, including joint
     ventures and preferred vendor relationships. In accordance with this
     strategy, (1) in September 1995, the Company and MCImetro Access
     Transmission Services, Inc. ("MCImetro"), a wholly-owned subsidiary of MCI
     Communications Corporation ("MCI"), formed a joint venture company to
     operate and expand the Company's existing networks in San Jose, California
     and its environs, and in May and June 1996, the Company and MCImetro
     entered into agreements which provide that, until September 30, 2001, the
     Company will be MCImetro's preferred provider of certain local access
     services in a number of the Company's
 
                                        6
<PAGE>   9
 
     markets and pursuant to which MCImetro acquired a minority investment in
     the Company's Sacramento, California network, and made an additional
     investment in the San Jose joint venture company (see "Recent Developments"
     below), and (2) in December 1995, the Company concluded a national
     preferred vendor agreement with AT&T Communications, Inc. ("AT&T
     Communications"), a wholly-owned subsidiary of AT&T Corp. ("AT&T"),
     pursuant to which the Company expects to become AT&T Communications'
     preferred supplier of local access services in most of the Company's
     markets. The Company believes preferred vendor relationships with IXCs
     provide opportunities to leverage its partners' sales channels and market
     support to sell the Company's products and services and expand the
     Company's potential revenue base. In addition, the Company believes that
     relationships with IXCs facilitate its entry into new markets by providing
     access between the IXCs and their customers. The Company has organized a
     national account marketing organization to manage such relationships. The
     Company believes this marketing effort, along with its number of cities
     served, financial resources and telecommunications expertise, position it
     well to develop and maintain these strategic relationships. See "Business
     of the Company -- Strategic Relationships."
 
          LEVERAGE UPON GLA'S SIGNIFICANT TELECOMMUNICATIONS INFRASTRUCTURE
     CAPABILITIES. GLA International, Inc. ("GLA"), a wholly-owned subsidiary of
     the Company, offers a full range of consulting, management, engineering and
     information system solutions for telecommunications companies. GLA provides
     a full range of network engineering, construction, design and strategic
     planning services, as well as financial and management software products,
     including specifically designed software for billing systems, toll rating,
     plant records and financial applications. GLA's capabilities also serve as
     an internal source for the telecommunications infrastructure support needed
     for the Company's CLEC business.
 
                              RECENT DEVELOPMENTS
 
     The Company has recently completed two acquisitions of long distance
service providers for small and medium-sized business customers in California to
complement its existing long distance and facilities management resale
businesses. Effective July 1, 1996, the Company acquired the stock of ALD
Communications, Inc. ("ALD"), a switchless reseller of long distance services
and a shared tenant service provider of telecommunications services primarily to
customers in the San Francisco, California area with aggregate annualized
revenues of approximately $6.4 million, based on August 1996 results. Effective
September 1, 1996, the Company also acquired Bittel Telecommunications
Corporation ("Bittel"), a switch-based long distance reseller serving the San
Francisco and Los Angeles markets with annualized revenues of approximately $9
million, based on July 1996 results. By acquiring ALD and Bittel, the Company
not only added businesses that complement its own long distance and facilities
management resale businesses but was also able to increase its end user sales
force.
 
     The Company believes that Internet and Intranet products and services
complement the Company's existing telecommunications services and present the
Company with potential revenue opportunities, through both the retention of
existing customers and the addition of new customers. To pursue such
opportunities, on June 25, 1996, the Company formed a strategic alliance with
World-Net Access, Inc. ("World-Net"), a privately-held development stage company
founded to form a national ISP network. The Company has invested a total of $20
million for a 25.5% fully-diluted interest in World-Net and it is possible that
the Company may commit additional funds in furtherance of this strategic
alliance. The Company intends that both companies will seek ways to work
together to provide customer oriented Internet and Intranet communications
solutions. The Company plans to develop and offer a wide range of
Internet-related services to users of World-Net's national ISP network,
including various dial-up and dedicated Internet access options.
 
     In accordance with the provisions of the agreements between the Company and
MCImetro (see "Corporate Strategy -- Build on strategic relationships" above),
on October 10, 1996, MCImetro
 
                                        7
<PAGE>   10
 
exchanged the agreed value of its investments in subsidiaries of the Company for
958,720 shares of the Company's Common Stock.
 
     On October 24, 1996, the Company and MaineCom Services, Inc. ("MaineCom"),
a subsidiary of Central Maine Power Company, entered into a letter of intent to
form a joint venture company, to be owned 60% by the Company and 40% by
MaineCom, for the purposes of constructing, owning, operating and developing
networks initially in Portland, Maine, and Nashua and Manchester, New Hampshire,
and other markets in Maine and New Hampshire as may be agreed upon by the
Company and MaineCom in the future. The proposal is subject to the negotiation
of definitive agreements approved by the respective Boards of Directors of the
Company and MaineCom.
 
     On November 7, 1996, the Company raised net proceeds of approximately
$217.2 million through the sale of $400.0 million aggregate principal amount of
the Private Notes. See "Financing Plan -- Debt Financing," below.
 
     On November 12, 1996, AT&T Credit Corporation ("AT&T Credit") exchanged the
agreed value of its investments in certain subsidiaries of the Company made in
connection with certain loans to the Company (see "Financing Plan -- Debt
Financing" below) for an aggregate of 234,260 shares of the Company's Common
Stock.
 
                                 FINANCING PLAN
 
     The Company believes its financing plan will enable it to implement the
pace and scope of its business strategy. To date, the Company has raised
financing primarily from the following sources:
 
          EQUITY CAPITAL. Through its May 1996 initial public offering (the
     "IPO") and two previous rounds of private equity financing, the Company
     raised approximately $292.3 million. Total pro forma contributed capital as
     of September 30, 1996 of $349.6 million reflects such public and private
     financing as well as equity capital received in connection with the City
     Signal Acquisition and the merger with BTC, and the issuance of 1,192,980
     shares in exchange for minority investments in the Company's subsidiaries
     and 1,569,599 shares upon exercise of warrants and options. On November 20,
     1996, the Company filed a Registration Statement on Form S-1 to register
     4,500,000 (assuming no exercise of any over-allotment options) of the
     Company's Depositary Shares, and the shares of preferred stock and common
     stock related thereto, to be offered to the public in a firm commitment
     underwritten public offering. See "Business of the Company -- Strategic
     Relationships," "Capitalization," "Certain Relationships and Related
     Transactions," and "Unaudited Pro Forma Combined Consolidated Financial
     Information."
 
          DEBT FINANCING. On November 7, 1996, the Company completed the
     issuance and sale of the Private Notes, for which the Company received
     proceeds net of underwriting discounts of approximately $217.2 million. On
     February 26, 1996, the Company completed the issuance and sale of $425.0
     million aggregate principal amount of 10 7/8% Senior Discount Notes due
     March 1, 2006 (the "10 7/8% Senior Discount Notes" and, together with the
     Private Notes, the "Senior Discount Notes"), for which the Company received
     proceeds net of underwriting discounts of approximately $241.0 million. The
     Company has also obtained secured financing under a line of credit from
     AT&T Credit, which totals $50.0 million (the "AT&T Credit Facility"), and a
     $10 million secured revolving line of credit for a subsidiary from Fleet
     National Bank (the "Bank Credit Facility"). See "Management's Discussion
     and Analysis of Financial Condition and Results of Operations -- Liquidity
     and Capital Resources."
 
     Historically, the Company has funded in advance its expected capital needs
for network construction and acquisition, as well as its needs for the
development and expansion of its networks. Following initial market entry, the
Company's capital deployment plans for the development and expansion of its
networks have been largely demand driven, including capital spending
 
                                        8
<PAGE>   11
 
necessary to take full advantage of the opportunities presented in the switched
services portion of the marketplace. The Company recently revised its network
development plans to provide for the Company to (i) increase the geographic
reach and robustness of its networks to allow the Company to serve a
significantly higher percentage of the market by extending its networks to serve
most, if not all, of the ILEC's central offices in its markets and (ii) more
rapidly deploy switches with full capabilities for local dial tone and switched
access termination and origination services. The Company's previous estimate of
capital spending during 1996 and 1997 to fund the development and expansion of
the Company's initial 30 networks was $290 million, of which $134.3 million was
spent through September 30, 1996. The Company now estimates that it will invest
an additional $200 million associated with its initial 30 networks to fund these
capital needs during 1997 and 1998. The Company currently intends to use the net
proceeds from the Depositary Shares Offering (see "Financing Plan -- Equity
Capital" above), along with additional financing to be obtained in the future,
to fund the Company's expansion from 30 to 40 networks by the end of 1997.
 
     The Company's longer-term strategy contemplates that the Company will have
networks serving a total of 50 cities in operation or under construction by the
end of 1998, which will require substantial additional capital. The Company's
expansion into additional cities is expected to be accomplished by the
acquisition of existing networks as well as the development of new networks. The
Company will continue to evaluate additional revenue opportunities in each of
its markets and other strategic initiatives, and, as attractive additional
opportunities may develop, the Company plans to make additional capital
investments in its networks that might be required to pursue such opportunities,
such as costs required to extend a network or install additional electronics to
meet specific customer requirements. The Company expects to meet its additional
capital needs with the proceeds from the sale of additional equity securities,
additional borrowings under existing and future credit facilities and joint
ventures. However, there can be no assurance that the Company will be able to
generate or raise sufficient capital to enable it to fully realize all of its
strategic objectives.
 
     The Company's expectations of required future capital expenditures are
based on the Company's current estimates. There can be no assurance that actual
expenditures will not be significantly higher or lower. See "Risk Factors --
Significant Future Capital Requirements; Substantial Indebtedness" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
                INFORMATION REGARDING FORWARD-LOOKING STATEMENTS
 
     The statements contained in this Prospectus which are not historical facts
are forward-looking statements that involve risks and uncertainties. Management
wishes to caution the reader that these forward-looking statements, such as the
Company's plans to have systems in operation or under construction in a total of
40 cities by the end of 1997 and 50 cities by the end of 1998 and its
expectations for the deployment of switches serving all of its operating
networks by the end of the second quarter of 1997, are only predictions; actual
events or results may differ materially as a result of risks facing the Company.
Such risks include, but are not limited to, the Company's ability to access
markets, identify, finance and complete suitable acquisitions, design fiber
optic backbone routes, install cable and facilities, including switching
electronics, and obtain rights-of-way, building access rights and any required
governmental authorizations, franchises and permits, all in a timely manner, at
reasonable costs and on satisfactory terms and conditions, as well as favorable
regulatory, legislative and judicial developments.

                               THE EXCHANGE OFFER
 
THE EXCHANGE OFFER............   The Company is hereby offering to exchange
                                 $1,000 principal amount of Exchange Notes for
                                 each $1,000 principal amount of Private Notes
                                 that are properly tendered and accepted. The
                                 Company will issue Exchange Notes on or as
                                 promptly as practicable after the Expiration
                                 Date. As of the date hereof, there is
                                 $400,000,000 aggregate principal amount of
                                 Private Notes outstanding. See "The Exchange
                                 Offer."
 
                                 Based on interpretations by the staff of the
                                 Commission set forth in no-action letters
                                 issued to third parties, the Company believes
                                 that the Exchange Notes issued pursuant to the
                                 Exchange Offer in exchange for Private Notes
                                 may be offered for resale, resold and otherwise
                                 transferred by a holder thereof without
                                 compliance with the registration and prospectus
                                 delivery provisions of the Securities Act,
                                 provided that the holder is acquiring Exchange
                                 Notes in the ordinary course of its business,
                                 is not participating and has no arrangement or
                                 understanding with any person to participate in
                                 the distribution of the Exchange Notes and is
                                 not an "affiliate" of the Company within the
                                 meaning of Rule 405 under the Securities Act.
                                 Each broker-dealer who holds Private Notes
                                 acquired for its own account as a result of
                                 market-making or other trading activities and
                                 who receives Exchange Notes pursuant to the

                                 therefor must acknowledge that it will deliver
                                 a prospectus in connection with any resale of
                                 such Exchange Notes.
 
                                 This Prospectus, as it may be amended or
                                 supplemented from time to time, may be used by
                                 a broker-dealer in connection with resales of
                                 Exchange Notes received in exchange for Private
                                 Notes acquired by such broker-dealer as a
                                 result of market-making activities or other
                                 trading activities. The Letter of Transmittal
                                 that accompanies this Prospectus states that by
                                 so acknowledging and by delivering a
                                 prospectus, a broker-dealer will not be deemed
                                 to admit that it is an "underwriter" within the
                                 meaning of the Securities Act. Any holder of
                                 Private Notes who tenders in the Exchange Offer
                                 with the intention to participate, or for the
                                 purpose of participating, in a distribution of
                                 the Exchange Notes could not rely on the
                                 above-referenced position of the staff of the
                                 commission and, in the absence of an exemption
                                 therefrom, would have to comply with the
                                 registration and prospectus delivery
                                 requirements of the Securities Act in
                                 connection with any resale transaction. Failure
                                 to comply with such requirements in such
                                 instance could result in such holder incurring

                                 acknowledge in the Letter of Transmittal that
                                 such holder will deliver a prospectus in
                                 connection with any resale of such Exchange

                                 delivering a prospectus, such holder will not
                                 be deemed to admit that it is an "underwriter"
                                 within the meaning of the Securities Act. See
                                 "The Exchange Offer -- Procedures for

BENEFICIAL OWNERS.............   Any beneficial owner whose Private Notes are
                                 registered in the name of a broker, dealer,
                                 commercial bank, trust company or other nominee
                                 and who wishes to tender such Private Notes in
                                 the Exchange Offer should contact such
                                 registered holder promptly and instruct such
                                 registered holder to tender on such beneficial
                                 owner's behalf. If such beneficial owner wishes
                                 to tender on such owner's own behalf, such
                                 owner must, prior to completing and executing
                                 the Letter of Transmittal and delivering such

                                 ownership may take considerable time and may
                                 not be able to be completed prior to the
                                 Expiration Date. See "The Exchange Offer --
                                 Procedures for Tendering."

     The Exchange Offer applies to $400,000,000 aggregate principal amount of
the Private Notes. The form and terms of the Exchange Notes are identical in all
material respects to the form and terms of the Private Notes except that the
exchange will have been registered under the Securities Act, and, therefore, the
Exchange Notes will not bear legends restricting the transfer thereof and
holders of the Exchange Notes will not be entitled to any of the registration
rights of holders of the Private Notes under the Registration Rights Agreement,
which rights will terminate upon consummation of the Exchange Offer. The
Exchange Notes will evidence the same indebtedness as the Private Notes (which
they replace) and will be issued under, and be entitled to the benefits of, the
Indenture. For further information and for definitions of certain capitalized
terms used below, see "Description of the Notes."
 
NOTES.........................   $400,000,000 principal amount of 11 7/8% Senior

INTEREST......................   The Notes accrete from November 7, 1996 at a
                                 rate of 11 7/8% compounded semi-annually, to an
                                 aggregate principal amount of $400,000,000 by
                                 November 1, 2001. No interest will be payable
                                 on the Notes prior to May 1, 2002. The Notes
                                 will accrue cash interest at the rate of
                                 11 7/8% per annum from November 1, 2001,
                                 payable semi-annually in arrears on November 1
                                 and May 1, commencing May 1, 2002.
 
YIELD.........................   11 7/8% per annum, computed on a semi-annual
                                 bond-equivalent basis and calculated from
                                 November 7, 1996.
 
RANKING.......................   The Notes are senior unsecured obligations of
                                 the Company, rank pari passu in right of
                                 payment with all existing and future senior
                                 unsecured obligations of the Company at the
                                 parent level and rank senior in right of
                                 payment to any future subordinated obligations
                                 of the Company at the parent level. However,
                                 holders of secured obligations of the Company
                                 (including obligations under the AT&T Credit

                                 to the assets securing such obligations. The
                                 Notes are effectively subordinated to all debt
                                 and other liabilities and commitments
                                 (including trade payables) of the Company's
                                 subsidiaries (including obligations under the
                                 Bank Credit Facility). As of September 30,

                                 secured indebtedness on November 12, 1996, (i)
                                 the total amount of outstanding liabilities of
                                 the Company (parent only), including trade
                                 payables, would have been approximately $546.8
                                 million, of which $50 million would have been
                                 secured obligations, and (ii) the total amount
                                 of outstanding liabilities of the Company's
                                 subsidiaries, including trade payables, would
                                 have been $14.1 million, of which $0.1 million
                                 would have represented secured obligations. See
                                 "--Covenants" below and "Description of Other
                                 Credit Facilities."

                                 Company, in whole or in part, at any time on or

                                 Equity Investment at a redemption price equal
                                 to 111.875% of the Accreted Value thereof.

                                 require the Company to purchase their Notes at
                                 a price equal to 101% of the Accreted Value
                                 thereof on or before November 1, 2001 or 101%
                                 of the stated principal amount thereof, plus
                                 accrued and unpaid interest, if any, thereon to
                                 the date of purchase, after November 1, 2001.
 
ORIGINAL ISSUE DISCOUNT.......   The issuance of the Private Notes resulted in
                                 original issue discount for United States
                                 federal income tax purposes. Thus, although
                                 interest will not accrue on the Notes prior to
                                 November 1, 2001, and there will be no periodic
                                 payments of interest on the Notes prior to May
                                 1, 2002, original issue discount (that is, the
                                 difference between the stated redemption price
                                 at maturity and the issue price of the Private
                                 Notes) will accrue from November 7, 1996 and
                                 will be includible as interest income
                                 periodically in a holder's gross income for
                                 United States federal income tax purposes in
                                 advance of receipt of the cash payments to
                                 which the income is attributable. See "Certain
                                 United States Federal Income Tax
                                 Considerations."
 
COVENANTS.....................   The indenture governing the Notes (the
                                 "Indenture") contains certain covenants that,
                                 among other things, limit 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. The Indenture permits the
                                 Company and its subsidiaries to incur, among
                                 other indebtedness, up to $160 million of
                                 secured indebtedness (including the AT&T Credit
                                 and Bank Facilities).
 
REPORTED PRICE RANGE..........   The Private Notes were designated for trading
                                 in the PORTAL market of the NASD effective
                                 November 7, 1996. During the period ended
                                 December 17, 1996, the range of reported high
                                 and low bid quotations for the Private Notes in
                                 the PORTAL market was $64.25 to $59.75,
                                 respectively. Such reported quotations may not
                                 reflect actual transactions. See "Price Range
                                 of the Private Notes."
 
BOOK-ENTRY, DELIVERY AND
FORMS.........................   It is expected that delivery of the Exchange
                                 Notes will be made in book-entry or
                                 certificated form. The Company expects that the
                                 Exchange Notes exchanged for Private Notes

      SUMMARY HISTORICAL AND PRO FORMA FINANCIAL AND OTHER OPERATING DATA
 
     The summary financial data presented below (other than the pro forma data)
as of and for the periods ended December 31, 1995, 1994 and 1993 are derived
from and qualified by reference to the audited consolidated financial statements
of the Company contained herein. The Company's consolidated financial statements
as of December 31, 1995, 1994 and 1993, and for the years ended December 31,
1995 and 1994, and for the period from inception to December 31, 1993, have been
audited by KPMG Peat Marwick LLP, independent auditors. The selected
consolidated financial data for the three months and nine months ended September
30, 1996 have been derived from the unaudited consolidated financial statements
of the Company, which have been prepared on the same basis as the audited
consolidated financial statements of the Company and, in the opinion of
management, reflect all normal recurring adjustments necessary for a fair
presentation of the financial position and results of operations as of the end
of and for such period. The results for the nine months ended September 30, 1996
are not necessarily indicative of the operating results to be expected for the
entire year. The unaudited pro forma statement of operations data for the year
ended December 31, 1995 gives effect to the merger with BTC and the City Signal
Acquisition using the purchase method of accounting and assuming that such
transactions were consummated on January 1, 1995. All of the summary financial
data should be read in conjunction with, and are qualified by reference to,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," the "Unaudited Pro Forma Combined Consolidated Financial
Information," and the Consolidated Financial Statements of the Company, BTC and
City Signal, Inc. and notes thereto contained elsewhere in this Prospectus.

</TABLE>
 
- ---------------
 (1) The Company was organized on November 10, 1993.
 (2) Minority interests represent the ownership interests of minority investors
     in certain of the Company's subsidiaries. Since September 30, 1996, the
     Company has issued an aggregate of 1,192,980 shares of Common Stock in
     exchange for all of the Company's then-existing minority interests.
 (3) Pro forma net loss per share has been computed using the number of shares
     of Common Stock and Common Stock equivalents outstanding. Pursuant to
     Securities and Exchange Commission Staff Accounting Bulletin No. 83, shares
     issued at prices below the May 1996 initial public offering price of $27.00
     per share, and stock options and warrants granted with exercise prices
     below the initial public offering price during the twelve-month period
     preceding the date of the initial filing of the Company's Registration
     Statement relating to the IPO have been included in the calculation of
     Common Stock equivalent shares for the nine months ended September 30,
     1996, using the treasury stock method, as if such shares, options and
     warrants were outstanding for all of 1995 and for the entire six-month
     period ended June 30, 1996. For the three months ended September 30, 1996,
     the weighted average number of shares was based on Common Stock outstanding
     and does not include common stock equivalents as their inclusion would be
     anti-dilutive.
 (4) EBITDA consists of net income (loss) before minority interests, interest,
     income taxes, depreciation and amortization. It is a measure commonly used
     in the telecommunications industry and is presented to assist in
     understanding the Company's operating results. However, it is not intended
     to represent cash flow in accordance with generally accepted accounting
     principles. See the Company's Consolidated Statements of Cash Flows
     appearing elsewhere in this Prospectus.
 (5) On a pro forma basis giving effect to (i) the sale of the Private Notes on
     November 7, 1996 and, (ii) the exchange of minority interests for shares of
     Common Stock and the exercise of warrants and options since September 30,
     1996. See "Capitalization."
 (6) Amount represents the total of Common Stock, additional paid-in capital,
     and Common Stock subject to redemption.
 (7) Amount represents paid-in capital less accumulated deficit. See note (6)
     above.
 (8) Voice grade equivalent circuits.
 (9) On a pro forma basis giving effect to the City Signal Acquisition.

                                  RISK FACTORS
 
     In addition to the other information contained in this Prospectus, the
following risk factors should be carefully considered in evaluating the Company
and its businesses before deciding to surrender Private Notes in exchange for
Exchange Notes pursuant to the Exchange Offer.
 
LIMITED HISTORY OF OPERATIONS; NEGATIVE CASH FLOW AND OPERATING LOSSES
 
     The Company was formed in November 1993. At January 1, 1996, only three of
the Company's networks that the Company acquired had been in operation for more
than 24 months. Prospective investors, therefore, have limited historical
financial information about the Company upon which to base an evaluation of the
Company's performance and an investment in shares of Common Stock of the
Company. Given the Company's limited operating history, there is no assurance
that it will be able to generate sufficient cash flow to service its debt and to
compete successfully in the telecommunications business.
 
     The development of the Company's businesses and the acquisition,
installation and expansion of its networks require significant expenditures, a
substantial portion of which are made before any revenues may be realized. Such
capital expenditures are expected to increase as the Company decides to pursue
opportunities created by the accelerated pace of regulatory changes designed to
open local exchange markets to CLEC competition. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources" and "Business of the Company -- CLEC Market Potential." These
expenditures, together with the associated early service costs, result in
negative cash flow and operating losses until an adequate revenue base may be
established. There can be no assurance that an adequate revenue base will be
established in each of the Company's systems. Since inception, the Company's
operations have resulted in earnings (losses) before minority interests,
interest, taxes, depreciation and amortization (EBITDA) of ($204,000) for the
period from November 10, 1993 through December 31, 1993, ($2.7) million for the
year ended December 31, 1994, ($4.4) million for the year ended December 31,
1995 and ($9.9) million for the nine months ended September 30, 1996. As of
September 30, 1996, the Company had an accumulated deficit of approximately
$40.4 million. On a pro forma basis, assuming the merger with BTC and the City
Signal Acquisition were completed on January 1, 1995, the Company would have had
EBITDA of ($8.5) million for the year ended December 31, 1995, and, assuming the
City Signal Acquisition was completed on January 1, 1996, the Company would have
had EBITDA of ($10.1) million on a pro forma basis for the nine months ended
September 30, 1996. EBITDA is a measure commonly used in the telecommunications
industry and is presented to assist in an understanding of the Company's
operating results. It is not intended to represent cash flow or results of
operations in accordance with generally accepted accounting principles. Certain
of the expenditures are expensed as incurred, while certain other expenditures
are capitalized. The Company will continue to incur expenditures in connection
with the acquisition, development and expansion of its networks, services and
customer base. There can be no assurance that the Company will achieve or
sustain profitability or generate sufficient positive cash flow to service its
debt.
 
SIGNIFICANT FUTURE CAPITAL REQUIREMENTS; SUBSTANTIAL INDEBTEDNESS
 
     Expansion of the Company's existing networks and services, the acquisition
and development of new networks and services and the funding of initial
operating losses will require significant capital expenditures. The Company
plans to have systems in operation or under construction in a total of 40 cities
by the end of 1997 and 50 cities by the end of 1998. The Company has deployed
switches serving substantially all of the Company's operating networks. The
Company is also adding capabilities to provide enhanced services such as high
speed video conferencing, frame relay and ATM-based packet transport services
and Internet access products and expects to offer such services in all of its
operating networks by the end of 1997. The Company currently intends to fund its
expansion from its initial 30 networks to 40 networks and the deployment of
switches in all of
 
                                       18
<PAGE>   21
 
such networks with full capabilities for local dial tone and switched access
termination and origination services, with the net proceeds from the Depositary
Shares Offering, together with additional financing to be obtained in the
future. The Company's growth into 50 cities and additional funds to support
other strategic initiatives will require substantial additional capital. The
Company will continue to evaluate additional revenue opportunities in each of
its markets and, as attractive additional opportunities may develop, the Company
plans to make additional capital investments in its networks that might be
required to pursue such opportunities. The Company expects to meet such
additional capital needs with additional borrowings under existing and future
credit facilities, proceeds from the sale of additional equity securities and
joint ventures. There can be no assurance, however, that the Company will be
successful in raising sufficient additional debt or equity capital on terms that
it will consider acceptable or that the Company's operations will produce
positive consolidated cash flow in sufficient amounts. 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.
 
     The Company's expectations of required future capital expenditures are
based on the Company's current estimates. There can be no assurance that actual
expenditures will not be significantly higher or lower.
 
     As of September 30, 1996, on a pro forma basis after giving effect to the
Private Note Offering and the conversion of $50 million aggregate principal
amount of subsidiary secured indebtedness to parent company secured indebtedness
on November 12, 1996, (i) the total amount of outstanding liabilities of the
Company (parent only), including trade payables, would have been approximately
$546.8 million, of which $50 million would have been secured obligations, and
(ii) the total amount of outstanding liabilities of the Company's subsidiaries,
including trade payables, would have been $14.1 million, of which $0.1 million
would have represented secured obligations. The Company expects to fund at least
a portion of its capital needs through additional borrowings, and there can be
no assurance as to the Company's ability to service its existing or future
indebtedness. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital Resources."
 
HOLDING COMPANY STRUCTURE; EFFECTIVE SUBORDINATION OF THE EXCHANGE NOTES
 
     The Company is a holding company which derives substantially all of its
revenues from its subsidiaries. The Exchange Notes are not secured by any of the
assets of the Company. The Indenture permits certain indebtedness of the Company
to be secured, including, among other things, purchase money indebtedness, which
the Indenture permits the Company to incur in unlimited amounts, and
indebtedness up to $160 million under secured credit facilities. Holders of any
secured indebtedness of the Company will have claims that are prior to the
claims of the holders of the Exchange Notes with respect to the assets securing
such other indebtedness. In addition, the Exchange Notes will be effectively
subordinated to indebtedness and other liabilities and commitments (including
trade payables) of the Company's subsidiaries. See "Description of the
Notes--Covenants--Limitation on Consolidated Debt" and "-- Limitation on Debt
and Preferred Stock of Subsidiaries."
 
     The Company will be dependent to some extent upon dividends and other
payments from its subsidiaries to generate the funds necessary to meet its
obligations, including the payment of principal of and interest on the Notes.
The ability of the Company's subsidiaries to make such payments will be subject
to, among other things, the availability of sufficient surplus funds and
restrictive covenants in subsidiary level and incurred debt covenants that may
restrict the ability of such subsidiaries to pay dividends to the Company.
However, the Company does not believe that such restrictions will have a
material impact on the Company's ability to meet its cash obligations. See
"-- No Dividends," "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital Resources" and "Description
of Other Credit Facilities."
 
                                       19
<PAGE>   22
 
RISKS ASSOCIATED WITH IMPLEMENTATION OF GROWTH STRATEGY
 
     The expansion and development of the Company's operations will depend,
among other things, on the Company's ability to assess markets, identify,
finance and complete suitable acquisitions, design fiber optic network backbone
routes, install cable and facilities, including switches, and obtain
rights-of-way, building access rights and any required government
authorizations, franchises and permits, all in a timely manner, at reasonable
costs and on satisfactory terms and conditions. As a result, there can be no
assurance that the Company will be able successfully to expand its existing
networks or acquire or develop new networks in a timely manner in accordance
with its strategic objectives.
 
     The Company expects to continue to enhance its systems in order to offer
its customers switched access termination and origination services and local
dial tone, centrex and desk top products, as well as other enhanced services in
all of its systems as quickly as practicable and as permitted by applicable
regulations. The Company believes its ability to offer, market and sell these
additional products and services will be important to the Company's ability to
meet its long term strategic growth objectives, but is dependent on the
Company's ability to obtain the needed capital, favorable regulatory,
legislative and judicial developments and the acceptance of such products and
services by the Company's customers. No assurance can be given that the Company
will be able to obtain such capital or that such developments or acceptance will
occur.
 
RISKS ASSOCIATED WITH POSSIBLE ACQUISITIONS
 
     The Company expects a substantial part of its future growth will come from
acquisitions. The acquisition of additional systems will depend on the Company's
ability to identify suitable acquisition candidates, to negotiate acceptable
terms for their acquisition and to finance any such acquisitions. The Company
will also be subject to competition for suitable acquisition candidates. Any
acquisitions, if made, could divert the resources and management time of the
Company and would require integration with the Company's existing networks and
services. As a result, there can be no assurance that any such acquisitions will
occur or that any such acquisitions, if made, would be made in a timely manner
or on terms favorable to the Company or would be successfully integrated into
the Company's operations.
 
COMPETITION
 
     In each of the cities served by the Company's networks, the services
offered by the Company compete principally with the services offered by the ILEC
serving that area. ILECs have long-standing relationships with their customers,
have the potential to subsidize competitive services from monopoly service
revenues, and benefit from favorable state and federal regulations. While the
FCC's Interconnection Decisions and the Telecommunications Act of 1996 provide
increased business opportunities to CLECs such as the Company, they also provide
the ILECs with increased pricing flexibility for their services and other
regulatory relief, which could also have a material adverse effect on CLECs,
including the Company. If the ILECs are allowed by regulators to lower their
rates for their services, engage in substantial volume and term discount pricing
practices for their customers, or seek to charge CLECs substantial fees for
interconnection to the ILECs' networks, the income of CLECs, including the
Company, could be materially adversely affected.
 
     The Company also faces, and expects to continue to face, competition from
other current and potential market entrants, including other CLECs, AT&T, MCI,
Sprint Corporation ("Sprint"), WorldCom, Inc. ("WorldCom") and other IXCs, cable
television companies, electric utilities, microwave carriers, wireless telephone
system operators and private networks built by large end users. In January 1994,
MCI announced that its MCImetro unit would invest more than $2.0 billion in
fiber optic rings and local switching equipment in major metropolitan markets in
the United States to provide direct connection to its customers and to provide
alternative local telephone services to other IXCs. The recently announced
acquisition of MCI by British Telecommunications could increase the resources
available to MCI for the above purposes. AT&T has also indicated its
 
                                       20
<PAGE>   23
 
intention to offer local telecommunications services in certain U.S. markets,
either directly or in conjunction with CLECs or cable operators, and WorldCom
and MFS Communications Company, Inc. ("MFS Communications"), a major CLEC, have
recently announced a merger. A continuing trend toward combinations and
strategic alliances in the telecommunications industry, including potential
consolidation among RBOCs, or among CLECs in second and third tier cities, or
transactions between telephone companies and cable companies outside of the
telephone company's service area, or between IXCs and CLECs, could give rise to
significant new competitors.
 
     The Company believes that various legislative initiatives, including the
Telecommunications Act of 1996, as well as a recent series of completed and
proposed transactions between ILECs, IXCs and cable companies, increase the
likelihood that barriers to local exchange competition will be removed more
quickly than had earlier been anticipated. The introduction of such competition,
however, also means that ILECs may be authorized to provide long distance
services under provisions of the Telecommunications Act of 1996 more quickly
than had earlier been anticipated. When ILECs are permitted to provide such
services, they will ultimately be in a position to offer single source service.
See "Regulatory Overview."
 
     The Company also competes with equipment vendors and installers, and
telecommunications management companies with respect to certain portions of its
business.
 
     Many of the Company's current and potential competitors have financial,
personnel and other resources substantially greater than those of the Company,
as well as other competitive advantages over the Company. See "Competition" for
more detailed information on the competitive environment faced by the Company.
 
DEPENDENCE ON BUSINESS FROM IXCS
 
     For the three months ended September 30, 1996, approximately 21% of the
Company's consolidated revenues were attributable to access services provided to
IXCs. Approximately 12% of such consolidated revenues were attributable to
services provided to MCI and its affiliates. The loss of access revenues from
IXCs in general or the loss of MCI as a customer could have a material adverse
effect on the Company's business. See "Business of the Company -- Strategic
Relationships" and "-- Sales and Marketing -- Wholesale Customers."
 
     In addition, the Company's growth strategy assumes increased revenues from
IXCs following the deployment of switches on its networks and the provision of
switched access origination and termination services. There is no assurance that
the IXCs will continue to increase their utilization of the Company's services,
or will not reduce or cease their utilization of the Company's services, which
could have a material adverse effect on the Company.
 
REGULATION
 
     The Company is subject to varying degrees of federal, state and local
regulation. The Company is not currently subject to price cap or rate of return
regulation, nor is it currently required to obtain FCC authorization for the
installation, acquisition or operation of its network facilities. However, the
FCC has determined that non-dominant carriers, such as the Company and its
subsidiaries, are required to file interstate tariffs on an ongoing basis. The
Company's subsidiaries that provide intrastate services are also generally
subject to certification and tariff filing requirements by state regulators.
Challenges to these tariffs by third parties could cause the Company to incur
substantial legal and administrative expenses. Although the trend in federal and
state regulation appears to favor increased competition, no assurance can be
given that changes in current or future regulations adopted by the FCC or state
regulators or other legislative or judicial initiatives relating to the
telecommunications industry would not have a material adverse effect on the
Company. In particular, the Company's belief that the entire $102 billion local
exchange market will open to CLEC competition depends upon continued favorable
pro-competitive regulatory changes, and the ability of the Company to compete in
these new market segments may be adversely affected by the greater
 
                                       21
<PAGE>   24
 
pricing flexibility and other regulatory relief granted to ILECs under the
Telecommunications Act of 1996. The partial stay of recent FCC rules that set
forth the amounts that ILECs can charge CLECs for access to the ILEC's networks
may slow the pace of open competition initiatives and result in individual
states having a more prominent role in the opening of local exchange markets to
competition. However, the Company believes that the partial stay will not have
any material adverse effect on the Company because the Company has in effect (or
expects to have in effect after state PUC arbitrations expected to be completed
by early 1997) interconnection agreements with the ILECs in all of its markets.
See "Regulatory Overview" for more detailed information on the regulatory
environment in which the Company operates.
 
NEED TO OBTAIN AND MAINTAIN PERMITS AND RIGHTS-OF-WAY
 
     In order to acquire and develop its networks, the Company must obtain local
franchises and other permits, as well as rights to utilize underground conduit
and pole space and other rights-of-way from entities such as ILECs and other
utilities, railroads, long distance providers, state highway authorities, local
governments and transit authorities. The Telecommunications Act of 1996 requires
that local governmental authorities treat telecommunications carriers in a
competitively neutral, non-discriminatory manner, and that most utilities,
including most ILECs and electric companies, afford CLECs access to their poles
and conduits and rights-of-way at reasonable rates on non-discriminatory terms
and conditions. There can be no assurance that the Company will be able to
maintain its existing franchises, permits and rights or to obtain and maintain
the other franchises, permits and rights needed to implement its business plan
on acceptable terms. Although the Company does not believe that any of the
existing arrangements will be cancelled, or will not be renewed, as needed,
cancellation or non-renewal of certain of such arrangements could materially
adversely affect the Company's business in the affected city. In addition, the
failure to enter into and maintain any such required arrangements for a
particular network, including a network which is already under construction, may
affect the Company's ability to develop that network. See "Business of the
Company -- Network Construction."
 
RAPID TECHNOLOGICAL CHANGES
 
     The telecommunications industry is subject to rapid and significant changes
in technology. While the Company believes that for the foreseeable future these
changes will neither materially affect the continued use of optical fiber
telecommunications networks nor materially hinder the Company's ability to
acquire necessary technologies, the effect of technological changes on the
businesses of the Company cannot be predicted. Thus, there can be no assurance
that technological developments will not have a material adverse effect on the
Company.
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's businesses are managed by a relatively small number of senior
management and operating personnel, the loss of certain of whom could have a
material adverse effect on the Company. See "Management." The Company believes
that its ability to manage its planned growth successfully will depend in large
part on its continued ability to attract and retain highly skilled and qualified
personnel. None of the Company's key executives has a written employment
agreement or non-compete agreement with the Company, nor does the Company
maintain key person life insurance on such persons. See "Management" for
detailed information on the Company's management and directors.
 
NO PRIOR PUBLIC MARKET FOR EXCHANGE NOTES; POSSIBLE VOLATILITY OF MARKET PRICE
OF EXCHANGE NOTES
 
     The NASD has designated the Private Notes as securities eligible for
trading in the PORTAL market of the NASD (see "Price Range of the Private
Notes"). However, the Exchange Notes are new securities for which there is
currently no market. The Company does not intend to apply for listing of the
Exchange Notes on any securities exchange or for inclusion of the Exchange Notes
in
 
                                       22
<PAGE>   25
 
any automated quotation system. The Company has been advised by each of the
Initial Purchasers that it currently intends to make a market in the Exchange
Notes. However, there can be no assurance as to the development or liquidity of
any market for the Exchange Notes. If a market for the Exchange Notes were to
develop, the Exchange Notes could trade at prices that may be higher or lower
than their Accreted Value depending upon many factors, including prevailing
interest rates, the Company's operating results and the markets for similar
securities. Historically, the market for non-investment grade debt has been
subject to disruptions that have caused substantial volatility in the prices of
securities similar to the Exchange Notes. There can be no assurance that, if a
market for the Exchange Notes were to develop, such a market would not be
subject to similar disruptions.
 
FAILURE TO EXCHANGE PRIVATE NOTES
 
     The Exchange Notes will be issued in exchange for Private Notes only after
timely receipt by the Exchange Agent of such Private Notes, a properly completed
and duly executed Letter of Transmittal and all other required documentation.
Therefore, holders of Private Notes desiring to tender such Private Notes in
exchange for Exchange Notes should allow sufficient time to ensure timely
delivery. Neither the Exchange Agent nor the Company is under any duty to give
notification of defects or irregularities with respect to tenders of Private
Notes for exchange. Private Notes that are not tendered or are tendered but not
accepted will, following consummation of the Exchange Offer, continue to be
subject to the existing restrictions upon transfer thereof. In addition, any
holder of Private Notes who tenders in the Exchange Offer for the purpose of
participating in a distribution of the Exchange Notes will be required to comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with any resale transaction. Each broker-dealer who holds Private
Notes acquired for its own account as a result of market-making or other trading
activities and who receives Exchange Notes for its own account in exchange for
such Private Notes pursuant to the Exchange Offer, must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. To
the extent that Private Notes are tendered and accepted in the Exchange Offer,
the trading market for untendered and tendered but unaccepted Private Notes
could be adversely affected due to the limited amount, or "float," of the
Private Notes that are expected to remain outstanding following the Exchange
Offer. Generally, a lower "float" of a security could result in less demand to
purchase such security and could, therefore, result in lower prices for such
security. For the same reason, to the extent that a large amount of Private
Notes are not tendered or are tendered and not accepted in the Exchange Offer,
the trading market for the Exchange Notes could be adversely affected. See "Plan
of Distribution" and "The Exchange Offer."
 
ORIGINAL ISSUE DISCOUNT; POSSIBLE UNFAVORABLE TAX AND OTHER LEGAL CONSEQUENCES
FOR HOLDERS OF THE EXCHANGE NOTES AND THE COMPANY
 
     The Private Notes were issued at a substantial discount from the stated
principal amount thereof. Consequently, purchasers of the Exchange Notes should
be aware that, although interest will not accrue on the Exchange Notes prior to
November 1, 2001, and there will be no periodic payments of cash interest on the
Exchange Notes prior to May 1, 2002, original issue discount (that is, the
difference between the stated redemption price at maturity and the issue price
of the Private Notes) will accrue from November 7, 1996 and will be includible
as interest income periodically (including for periods ending prior to November
1, 2001) in a holder's gross income for U.S. federal income tax purposes in
advance of receipt of the cash payments to which the income is attributable.
Similar results may apply under state and other tax laws.
 
     If a bankruptcy case is commenced by or against the Company under the U.S.
Bankruptcy Code after the issuance of the Exchange Notes, the claim of a holder
of Exchange Notes with respect to the principal amount thereof may be limited to
an amount equal to the sum of (i) the initial offering price of the Private
Notes and (ii) that portion of the original issue discount that is not deemed to
constitute "unmatured interest" for purposes of the U.S. Bankruptcy Code. Any
original issue
 
                                       23
<PAGE>   26
 
discount that was not amortized as of any such bankruptcy filing would
constitute "unmatured interest."
 
     See "Certain United States Federal Income Tax Consequences" for a more
detailed discussion of the federal income tax consequences to the holders
regarding the purchase, ownership and disposition of the Notes.
 
                        NO CASH PROCEEDS TO THE COMPANY
 
     This Exchange Offer is intended to satisfy certain obligations of the
Company under the Registration Rights Agreement. The Company will not receive
any proceeds from the issuance of the Exchange Notes offered hereby and has
agreed to pay the expenses of the Exchange Offer. In consideration for issuing
the Exchange Notes as contemplated in this Prospectus, the Company will receive,
in exchange, Private Notes in like principal amount. The form and terms of the
Exchange Notes are identical in all material respects to the form and terms of
the Private Notes, except as otherwise described herein under "The Exchange
Offer -- Terms of the Exchange Offer." The Private Notes surrendered in exchange
for the Exchange Notes will be retired and cancelled and cannot be reissued.
Accordingly, issuance of the Exchange Notes will not result in any increase in
the outstanding debt of the Company.

                               THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
     The Private Notes were sold by the Company on November 7, 1996 (the
"Closing Date") to the Initial Purchasers pursuant to the Purchase Agreement.
The Initial Purchasers subsequently sold the Private Notes to (i) "qualified
institutional buyers" ("QIBs"), as defined in Rule 144A under the Securities Act
("Rule 144A"), in reliance on Rule 144A and (ii) a limited number of
institutional "accredited investors" ("Accredited Institutions"), as defined in
Rule 501(a)(1), (2), (3) or (7) under the Securities Act. As a condition to the
sale of the Private Notes, the Company and the Initial Purchasers entered into
the Registration Rights Agreement on November 7, 1996. Pursuant to the
Registration Rights Agreement, the Company agreed that it would (i) use its best
efforts to file with the Commission within 60 days after the Closing Date a
registration statement under the Securities Act with respect to the Exchange
Notes and (ii) use its reasonable best efforts to cause such Registration
Statement to become effective under the Securities Act within 90 days after the
Closing Date. The Company agreed to issue and exchange Exchange Notes for all
Private Notes validly tendered and not withdrawn before the expiration of the
Exchange Offer. A copy of the Registration Rights Agreement has been filed as an
exhibit to the Registration Statement of which this Prospectus is a part. The
Registration Statement is intended to satisfy certain of the Company's
obligations under the Registration Rights Agreement and the Purchase Agreement.
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Private
Notes validly tendered and not withdrawn prior to the Expiration Date.
 
     The Company will issue $1,000 principal amount of Exchange Notes in
exchange for each $1,000 principal amount of outstanding Private Notes validly
tendered pursuant to the Exchange Offer and not withdrawn prior to the
Expiration Date. Private Notes may be tendered only in integral multiples of
$1,000.
 
     The form and terms of the Exchange Notes are the same as the form and terms
of the Private Notes except that (i) the exchange will be registered under the
Securities Act and, therefore, the Exchange Notes will not bear legends
restricting the transfer thereof and (ii) holders of the Exchange Notes will not
be entitled to any of the registration rights of holders of Private Notes under
the Registration Rights Agreement, which rights will terminate upon the
consummation of the Exchange Offer. The Exchange Notes will evidence the same
indebtedness as the Private Notes (which they replace) and will be issued under,
and be entitled to the benefits of, the Indenture, which also authorized the
issuance of the Private Notes, such that both series of Notes will be treated as
a single class of debt securities under the Indenture.
 
     As of the date of this Prospectus, $400,000,000 in aggregate principal
amount of the Private Notes is outstanding, all of which is registered in the
name of Cede & Co., as nominee for The Depository Trust Company (the
"Depository"). Only a registered holder of the Private Notes (or such holder's
legal representative or attorney-in-fact) as reflected on the records of the
Trustee under the Indenture may participate in the Exchange Offer. Solely for
reasons of administration, the Company has fixed the close of business on
December 20, 1996 as the record date for the Exchange Offer for purposes of
determining the persons to whom this Prospectus and the Letter of Transmittal
will be mailed initially. There will be no fixed record date for determining
registered holders of the Private Notes entitled to participate in the Exchange
Offer.
 
     Holders of the Private Notes do not have any appraisal or dissenters'
rights under the General Corporation Law of the State of Delaware or the
Indenture in connection with the Exchange Offer. The Company intends to conduct
the Exchange Offer in accordance with the provisions of the Registration Rights
Agreement and the applicable requirements of the Securities Act and the rules
and regulations of the Commission thereunder.
 
                                       26
<PAGE>   29
 
     The Company shall be deemed to have accepted validly tendered Private Notes
when, and if, the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
of Private Notes for the purposes of receiving the Exchange Notes from the
Company.
 
     Holders who tender Private Notes in the Exchange Offer will not be required
to pay brokerage commissions or fees or, subject to the instructions in the
Letter of Transmittal, transfer taxes with respect to the exchange of Private
Notes pursuant to the Exchange Offer. The Company will pay all charges and
expenses, other than certain applicable taxes described below, in connection
with the Exchange Offer. See " -- Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
     The term "Expiration Date" shall mean 5:00 p.m., New York City time on
            , 1997, unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended.
 
     In order to extend the Exchange Offer, the Company will (i) notify the
Exchange Agent of any extension by oral or written notice, (ii) mail to the
registered holders an announcement thereof and (iii) issue a press release or
other public announcement which shall include disclosure of the approximate
number of Private Notes deposited to date, each prior to 9:00 a.m., New York
City time, on the next business day after the previously scheduled Expiration
Date.
 
     The Company reserves the right, in its sole discretion, (i) to delay
accepting any Private Notes, (ii) to extend the Exchange Offer or (iii) if, in
the opinion of counsel for the Company, the consummation of the Exchange Offer
would violate any applicable law, rule or regulation or any applicable
interpretation of the staff of the Commission, to terminate or amend the
Exchange Offer by giving oral or written notice of such delay, extension,
termination or amendment to the Exchange Agent. Any such delay in acceptance,
extension, termination or amendment will be followed as promptly as practicable
by oral or written notice thereof to the registered holders. If the Exchange
Offer is amended in a manner determined by the Company to constitute a material
change, the Company will promptly disclose such amendment by means of a
prospectus supplement that will be distributed to the registered holders, and
the Company will extend the Exchange Offer for a period of five to ten business
days, depending upon the significance of the amendment and the manner of
disclosure to the registered holders, if the Exchange Offer would otherwise
expire during such five to ten business day period.
 
     Without limiting the manner in which the Company may choose to make a
public announcement of any delay, extension, amendment or termination of the
Exchange Offer, the Company shall have no obligation to publish, advertise, or
otherwise communicate any such public announcement, other than by making a
timely release to an appropriate news agency.
 
INTEREST ON THE EXCHANGE NOTES
 
     The Private Notes and the Exchange Notes accrete from November 7, 1996 at a
rate equal to 11 7/8% compounded semi-annually to an aggregate principal amount
of $400,000,000 by November 1, 2001. No interest will be payable on the Notes
prior to May 1, 2002. The Notes will accrue cash interest at the rate of 11 7/8%
per annum from November 1, 2001, payable semi-annually in arrears on May 1 and
November 1 of each year, commencing May 1, 2002.
 
RESALE OF THE EXCHANGE NOTES
 
     With respect to the Exchange Notes, based upon interpretations by the staff
of the Commission set forth in certain no-action letters issued to third
parties, the Company believes that a holder who exchanges Private Notes for
Exchange Notes in the ordinary course of business, who is not participating,
does not intend to participate, and has no arrangement with any person to
participate in a distribution of the Exchange Notes, and who is not an
"affiliate" of the Company within the meaning of Rule 405 of the Securities Act,
will be allowed to resell Exchange Notes to the public
 
                                       27
<PAGE>   30
 
without further registration under the Securities Act and without delivering to
the purchasers of the Exchange Notes a prospectus that satisfies the
requirements of Section 10 of the Securities Act. However, if any holder
acquires Exchange Notes in the Exchange Offer for the purpose of distributing or
participating in the distribution of the Exchange Notes, such holder cannot rely
on the position of the staff of the Commission enumerated in certain no-action
letters issued to third parties and must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale transaction, unless an exemption from registration is otherwise
available. Each broker-dealer that receives Exchange Notes for its own account
in exchange for Private Notes acquired by such broker-dealer as a result of
market-making or other trading activities must acknowledge that it will deliver
a prospectus in connection with any resale of such Exchange Notes. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of any Exchange Notes received in exchange for Private Notes
acquired by such broker-dealer as a result of market-making or other trading
activities. Pursuant to the Registration Rights Agreement, the Company has
agreed to make this Prospectus, as it may be amended or supplemented from time
to time, available to any such broker-dealer that requests copies of such
Prospectus in the Letter of Transmittal for use in connection with any such
resale for a period of up to 90 days after the Expiration Date. See "Plan of
Distribution."
 
PROCEDURES FOR TENDERING
 
     Only a registered holder of Private Notes may tender such Private Notes in
the Exchange Offer. To tender in the Exchange Offer, a holder of Private Notes
must complete, sign and date the Letter of Transmittal, or a facsimile thereof,
have the signatures thereon guaranteed if required by the Letter of Transmittal,
and mail or otherwise deliver such Letter of Transmittal or such facsimile to
the Exchange Agent at the address set forth below under "-- Exchange Agent" for
receipt prior to the Expiration Date. In addition, either (i) certificates for
such Private Notes must be received by the Exchange Agent along with the Letter
of Transmittal, (ii) a timely confirmation of a book-entry transfer (a
"Book-Entry Confirmation") of such Private Notes, if such procedure is
available, into the Exchange Agent's account at the Depository pursuant to the
procedure for book-entry transfer described below, must be received by the
Exchange Agent prior to the Expiration Date or (iii) the holder must comply with
the guaranteed delivery procedures described below.
 
     The tender by a holder that is not withdrawn prior to the Expiration Date
will constitute an agreement between such holder and the Company in accordance
with the terms and subject to the conditions set forth herein and in the Letter
of Transmittal.
 
     THE METHOD OF DELIVERY OF PRIVATE NOTES AND THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK
OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE
AN OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY INSURED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. DO NOT SEND THE LETTER OF TRANSMITTAL OR ANY PRIVATE
NOTES TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.
 
     Any beneficial owner(s) of the Private Notes whose Private Notes are
registered in the name of a broker, dealer, commercial bank, trust company or
other nominee and who wishes to tender should contact the registered holder
promptly and instruct such registered holder to tender on such beneficial
owner's behalf. If such beneficial owner wishes to tender on such owner's own
behalf, such owner must, prior to completing and executing the Letter of
Transmittal and delivering such owner's Private Notes, either make appropriate
arrangements to register ownership of the Private Notes in such owner's name or
obtain a properly completed bond power from the registered holder. The transfer
of registered ownership may take considerable time.
 
                                       28
<PAGE>   31
 
     Signatures on a Letter of Transmittal or a notice of withdrawal described
below (see "-- Withdrawal of Tenders"), as the case may be, must be guaranteed
by an Eligible Institution (as defined below) unless the Private Notes tendered
pursuant thereto are tendered (i) by a registered holder who has not completed
the box titled "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution. In the event that signatures on
a Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantee must be made by a member firm of a
registered national securities exchange or of the NASD, a commercial bank or
trust company having an office or correspondent in the United States or an
"eligible guarantor institution" within the meaning of Rule 17Ad-15 under the
Exchange Act which is a member of one of the recognized signature guarantee
programs identified in the Letter of Transmittal (an "Eligible Institution").
 
     If the Letter of Transmittal is signed by a person other than the
registered holder of any Private Notes listed therein, such Private Notes must
be endorsed or accompanied by a properly completed bond power, signed by such
registered holder exactly as such registered holder's name appears on such
Private Notes.
 
     If the Letter of Transmittal or any Private Notes or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and, unless waived by the Company,
evidence satisfactory to the Company of their authority to so act must be
submitted with the Letter of Transmittal.
 
     The Exchange Agent and the Depository have confirmed that any financial
institution that is a participant in the Depository's system may utilize the
Depository's Automated Tender Offer Program to tender Private Notes.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Private Notes will be determined
by the Company in its sole discretion, which determination will be final and
binding. The Company reserves the absolute right to reject any and all Private
Notes not properly tendered or any Private Notes the Company's acceptance of
which would, in the opinion of counsel for the Company, be unlawful. The Company
also reserves the right to waive any defects, irregularities or conditions of
tender as to particular Private Notes. The Company's interpretation of the terms
and conditions of the Exchange Offer (including the instructions in the Letter
of Transmittal) will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of Private Notes must be
cured within such time as the Company shall determine. Although the Company
intends to notify holders of defects or irregularities with respect to tenders
of Private Notes, neither the Company, the Exchange Agent nor any other person
shall incur any liability for failure to give such notification. Tenders of
Private Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived.
 
     While the Company has no present plan to acquire any Private Notes that are
not tendered in the Exchange Offer or to file a registration statement to permit
resales of any Private Notes that are not tendered pursuant to the Exchange
Offer, the Company reserves the right in its sole discretion to purchase or make
offers for any Private Notes that remain outstanding subsequent to the
Expiration Date and, to the extent permitted by applicable law, purchase Private
Notes in the open market, in privately negotiated transactions or otherwise. The
terms of any such purchases or offers could differ from the terms of the
Exchange Offer.
 
     By tendering Private Notes pursuant to the Exchange Offer, each holder of
Private Notes will represent to the Company that, among other things, (i) the
Exchange Notes to be acquired by such holder of Private Notes in connection with
the Exchange Offer are being acquired by such holder in the ordinary course of
business of such holder, (ii) such holder has no arrangement or understanding
with any person to participate in the distribution of the Exchange Notes, (iii)
such holder acknowledges and agrees that any person who is a broker-dealer
registered under the Exchange Act or is participating in the Exchange Offer for
the purposes of distributing the Exchange Notes must comply with the
registration and prospectus delivery requirements of the Securities Act in
 
                                       29
<PAGE>   32
 
connection with a secondary resale transaction of the Exchange Notes acquired by
such person and cannot rely on the position of the staff of the Commission set
forth in certain no-action letters, (iv) such holder understands that a
secondary resale transaction described in clause (iii) above and any resales of
Exchange Notes obtained by such holder in exchange for Private Notes acquired by
such holder directly from the Company should be covered by an effective
registration statement containing the selling security holder information
required by Item 507 or Item 508, as applicable, of Regulation S-K of the
Commission and (v) such holder is not an "affiliate," as defined in Rule 405
under the Securities Act, of the Company. If the holder is a broker-dealer that
will receive Exchange Notes for such holder's own account in exchange for
Private Notes that were acquired as a result of market-making activities or
other trading activities, such holder will be required to acknowledge in the
Letter of Transmittal that such holder will deliver a prospectus in connection
with any resale of such Exchange Notes; however, by so acknowledging and by
delivering a prospectus, such holder will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
 
RETURN OF PRIVATE NOTES
 
     If any tendered Private Notes are not accepted for any reason set forth in
the terms and conditions of the Exchange Offer or if Private Notes are withdrawn
or are submitted for a greater principal amount than the holders desire to
exchange, such unaccepted, withdrawn or non-exchanged Private Notes will be
returned without expense to the tendering holder thereof (or, in the case of
Private Notes tendered by book-entry transfer into the Exchange Agent's account
at the Depository pursuant to the book-entry transfer procedures described
below, such Private Notes will be credited to an account maintained with the
Depository) as promptly as practicable.
 
BOOK-ENTRY TRANSFER
 
     The Exchange Agent will make a request to establish an account with respect
to the Private Notes at the Depository for purposes of the Exchange Offer within
two business days after the date of this Prospectus, and any financial
institution that is a participant in the Depository's systems may make
book-entry delivery of Private Notes by causing the Depository to transfer such
Private Notes into the Exchange Agent's account at the Depository in accordance
with the Depository's procedures for transfer. However, although delivery of
Private Notes may be effected through book-entry transfer at the Depository, the
Letter of Transmittal or facsimile thereof, with any required signature
guarantees and any other required documents, must, in any case, be transmitted
to and received by the Exchange Agent at the address set forth below under
"-- Exchange Agent" on or prior to the Expiration Date or pursuant to the
guaranteed delivery procedures described below.
 
GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their Private Notes and (i) whose Private Notes
are not immediately available or (ii) who cannot deliver their Private Notes,
the Letter of Transmittal or any other required documents to the Exchange Agent
prior to the Expiration Date, may effect a tender if:
 
     (a) The tender is made through an Eligible Institution;
 
     (b) Prior to the Expiration Date, the Exchange Agent receives from such
Eligible Institution a properly completed and duly executed Notice of Guaranteed
Delivery substantially in the form provided by the Company (by facsimile
transmission, mail or hand delivery) setting forth the name and address of the
holder, the certificate number(s) of such Private Notes and the principal amount
of Private Notes tendered, stating that the tender is being made thereby and
guaranteeing that, within five New York Stock Exchange trading days after the
Expiration Date, the Letter of Transmittal (or a facsimile thereof), together
with the certificate(s) representing the Private Notes in proper form for
transfer or a Book-Entry Confirmation, as the case may be, and any other
documents required by the Letter of Transmittal, will be deposited by the
Eligible Institution with the Exchange Agent; and
 
     (c) Such properly executed Letter of Transmittal (or facsimile thereof), as
well as the certificate(s) representing all tendered Private Notes in proper
form for transfer and all other
 
                                       30
<PAGE>   33
 
documents required by the Letter of Transmittal are received by the Exchange
Agent within five New York Stock Exchange trading days after the Expiration
Date.
 
     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Private Notes according to the
guaranteed delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
     Except as otherwise provided herein, tenders of Private Notes may be
withdrawn at any time prior to the Expiration Date.
 
     To withdraw a tender of Private Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to the Expiration Date. Any such
notice of withdrawal must (i) specify the name of the person having deposited
the Private Notes to be withdrawn (the "Depositor"), (ii) identify the Private
Notes to be withdrawn (including the certificate number or numbers and principal
amount of such Private Notes) and (iii) be signed by the holder in the same
manner as the original signature on the Letter of Transmittal by which such
Private Notes were tendered (including any required signature guarantees). All
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by the Company, in its sole discretion, whose
determination shall be final and binding on all parties. Any Private Notes so
withdrawn will be deemed not to have been validly tendered for purposes of the
Exchange Offer, and no Exchange Notes will be issued with respect thereto unless
the Private Notes so withdrawn are validly retendered. Properly withdrawn
Private Notes may be retendered by following one of the procedures described
above under "The Exchange Offer -- Procedures for Tendering" at any time prior
to the Expiration Date.
 
TERMINATION OF CERTAIN RIGHTS
 
     All registration rights under the Registration Rights Agreement accorded to
holders of the Private Notes (and all rights to receive additional interest in
the event of a Registration Default as defined therein) will terminate upon
consummation of the Exchange Offer except with respect to the Company's
continuing obligation for a period of up to 90 days after the Expiration Date to
keep the Registration Statement effective and to provide copies of the latest
version of the Prospectus to any broker-dealer that requests copies of such
Prospectus in the Letter of Transmittal for use in connection with any resale by
such broker-dealer of Exchange Notes received for its own account pursuant to
the Exchange Offer in exchange for Private Notes acquired for its own account as
a result of market-making or other trading activities.

Offer. Questions and requests for assistance, requests for additional copies of

FEES AND EXPENSES
 
     The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, facsimile transmission, telephone or in person by
officers and regular employees of the Company and its affiliates.
 
     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable, out-of-pocket expenses in connection therewith.
 
     The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company and are estimated in the aggregate to be approximately
$125,000. Such expenses include registration fees, fees and expenses of the
Exchange Agent and the Trustee, accounting and legal fees, and printing costs,
among others.
 
     The Company will pay all transfer taxes, if any, applicable to the exchange
of Private Notes pursuant to the Exchange Offer. If, however, a transfer tax is
imposed for any reason other than the exchange of the Private Notes pursuant to
the Exchange Offer, then the amount of any such transfer taxes (whether imposed
on the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption therefrom
is not submitted with the Letter of Transmittal, the amount of such transfer
taxes will be billed directly to such tendering holder.
 
CONSEQUENCE OF FAILURE TO EXCHANGE
 
     Participation in the Exchange Offer is voluntary. Holders of the Private
Notes are urged to consult their financial and tax advisors in making their own
decisions on what action to take.
 
     Private Notes that are not exchanged for the Exchange Notes pursuant to the
Exchange Offer will remain "restricted securities" within the meaning of Rule
144(a)(3)(iv) of the Securities Act. Accordingly, such Private Notes may not be
offered, sold, pledged or otherwise transferred except (i) to a person whom the
seller reasonably believes is a "qualified institutional buyer" within the
meaning of Rule 144A under the Securities Act purchasing for its own account or
for the account of a qualified institutional buyer in a transaction meeting the
requirements of Rule 144A, (ii) in an offshore transaction complying with Rule
903 or Rule 904 of Regulation S under the Securities Act, (iii) pursuant to an
exemption from registration under the Securities Act provided by Rule 144
thereunder (if available), (iv) pursuant to an effective registration statement
under the Securities Act or (v) to institutional accredited investors in a
transaction exempt from the registration requirements of the Securities Act,
and, in each case, in accordance with all other applicable securities laws.
 
ACCOUNTING TREATMENT
 
     For accounting purposes, the Company will recognize no gain or loss as a
result of the Exchange Offer. The expenses of the Exchange Offer will be
amortized over the remaining term of the Notes.

                SELECTED HISTORICAL AND PRO FORMA FINANCIAL AND
                              OTHER OPERATING DATA
 
     The selected financial data presented below (other than the pro forma data)
as of and for the periods ended December 31, 1995, 1994 and 1993 are derived
from and qualified by reference to the audited consolidated financial statements
of the Company contained herein. The Company's consolidated financial statements
as of December 31, 1995, 1994 and 1993, and for the years ended December 31,
1995 and 1994, and for the period from inception to December 31, 1993, have been
audited by KPMG Peat Marwick LLP, independent auditors. The selected
consolidated financial data for the three months ended September 30, 1996 and
the nine months ended September 30, 1995 and 1996 have been derived from the
unaudited consolidated financial statements of the Company, which have been
prepared on the same basis as the audited consolidated financial statements of
the Company and, in the opinion of management, reflect all normal recurring
adjustments necessary for a fair presentation of the financial position and
results of operations as of the end of and for such period. The results for the
nine months ended September 30, 1996 are not necessarily indicative of the
operating results to be expected for the entire year. The unaudited pro forma
statement of operations data for the year ended December 31, 1995 gives effect
to the merger with BTC and the City Signal Acquisition using the purchase method
of accounting and assuming that such transactions were consummated on January 1,
1995. All of the selected financial data should be read in conjunction with, and
are qualified by reference to, "Management's Discussion and Analysis of
Financial Condition and Results of Operations," the "Unaudited Pro Forma
Combined Consolidated Financial Information," and the Consolidated Financial
Statements of the Company, BTC and City Signal, Inc. and notes thereto contained
elsewhere in this Prospectus.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
the Company's audited Consolidated Financial Statements and the notes thereto
appearing elsewhere in this Prospectus.
 
OVERVIEW
 
     The Company is a leading full service provider of competitive local
telecommunications services in selected markets in the United States. The
Company acquires and constructs its own state-of-the-art fiber optic networks
and facilities and leases network capacity from others to provide IXCs, ISPs,
wireless carriers and business, government and institutional end-users with an
alternative to the ILECs for a broad array of high quality voice, data, video
transport and other telecommunications services.
 
     The Company's goal is to become the primary full service provider of
competitive local telecommunications services to IXCs, ISPs, wireless carriers
and business, government and institutional end-users in selected cities by
offering superior products with excellent customer service at prices below those
charged by the ILECs. The Company currently has systems in 30 cities, consisting
of systems in operation in 22 cities and under construction in eight cities. The
Company plans to expand its network operations to have systems in operation or
under construction in a total of 50 cities by the end of 1998. The Company has a
total of 20 digital telephone switches installed in its networks. The Company
has deployed switches to offer local dial tone, switched access termination and
origination services, centrex, and desktop products in substantially all of its
operating networks, and expects to have switches installed in all of its
operating networks by the end of the second quarter of 1997. The Company is also
adding capabilities to provide enhanced services such as high speed video
conferencing, frame relay and ATM-based packet transport services and Internet
access products and expects to offer all of such services in all of its
operating networks by the end of 1997.
 
     On January 31, 1996, the Company completed the City Signal Acquisition
which included networks in operation or under construction in four cities in
Michigan and Ohio, including an installed switch in Grand Rapids, Michigan. At
the date of acquisition, the acquired networks had approximately 208 route miles
of fiber, 30,456 VGE circuits and 226 buildings connected. In addition,
effective January 2, 1996, BTC, a founding stockholder of the Company, was
merged into the Company. GLA, a wholly owned subsidiary of the Company, offers a
full range of consulting, management, engineering and information systems
solutions for telecommunications companies. GLA's capabilities also serve as an
internal source for the telecommunications infrastructure support needed to
facilitate the Company's network growth and penetration of the CLEC business.

Relationships and Related Transactions" and "Unaudited Pro Forma Combined
Consolidated Financial Information."

RESULTS OF OPERATIONS
 
THREE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 1995
 
     REVENUES
 
     The Company's revenues increased to $12.9 million for the three months
ended September 30, 1996 from $3.8 million for the three months ended September
30, 1995, an increase of 241%. Network capacity as reflected in VGEs in service
increased to 358,640 VGEs as of September 30, 1996 as compared with 108,841 VGEs
as of September 30, 1995. These increases reflect the impact of the Company's
acquisition and development activities, including an increase in the number of
networks in operation to 22 from 11 in the third quarter of 1995, as well as
increased utilization of the Company's network facilities arising from the sales
of additional services to current and new customers. A significant contributor
to the Company's revenue growth for the third quarter of 1996 relates to the
Company's entry into local exchange services in Grand Rapids, Michigan.
Annualized monthly local exchange services revenues increased from $6.4 million
based on June 1996 revenues to $10.2 million based on September 1996 revenues,
as a result of rapidly growing revenues in Grand Rapids. Local exchange services
revenues for the quarter ended September 30, 1996, totaled $2.2 million as
compared to $1.4 million for the quarter ended June 30, 1996.
 
     COSTS AND EXPENSES
 
     Service costs increased to $6.1 million for the three months ended
September 30, 1996 from $1.8 million for the three months ended September 30,
1995. The increase was due primarily to the increasing costs associated with the
Company's rapidly growing local exchange services in Grand Rapids and its
expanding resale operations. Service costs consist of costs associated directly
with the operation of the Company's networks, facilities management services,
and consulting and system support activities for third parties including local
and long distance service costs, technical salaries and benefits, and
rights-of-way fees.
 
     The Company's selling, general and administrative ("SG&A") expenses for the
three months ended September 30, 1996 were $10.2 million, as compared with SG&A
expenses of $3.0 million for the three months ended September 30, 1995. The
increase was principally due to the increasing number and continued expansion of
the Company's competitive access networks, including added personnel costs and
marketing activities related to the introduction of switched services. There is
typically a period of higher SG&A expenses and a lag time in the generation of
revenues following the acquisition and development of a competitive access
network. Management expects SG&A
 
                                       36
<PAGE>   39
 
expenses to continue to increase during the remainder of 1996 as the Company
continues to expand its networks, services and marketing activities.
 
     Depreciation and amortization expense increased to $4.3 million for the
three months ended September 30, 1996, from $1.1 million for the three months
ended September 30, 1995 as a result of the Company's acquisitions and the
continued expansion of the Company's networks.
 
     INTEREST INCOME (EXPENSE)
 
     Interest expense totaling $7.7 million was recorded during the three months
ended September 30, 1996, as compared to interest expense of $965,000 for the
three months ended September 30, 1995. The primary contributor to the
substantial increase in interest expense as compared to the comparable period in
the prior year is non-cash interest expense totaling $6.4 million attributable
to accretion of the 10 7/8% Senior Discount Notes (see "Liquidity and Capital
Resources") issued by the Company on February 26, 1996. In addition, capitalized
interest of $802,000 was recorded for the quarter ended September 30, 1996,
related to network construction projects. For the quarters ended September 30,
1996 and 1995, interest income totaling $4.8 million and $569,000, respectively,
was derived from the Company's available cash and cash equivalents and
marketable securities.
 
     NET LOSS
 
     For the reasons stated above, the Company's net loss before minority
interest increased to $10.4 million for the quarter ended September 30, 1996,
from $2.6 million for the quarter ended September 30, 1995. Minority interests
in net losses, representing minority investors' interests in certain of the
Company's subsidiaries, totaled $451,000 and $271,000 for the quarters ended
September 30, 1996 and 1995, respectively. As a result, the Company's net loss
for the quarter ended September 30, 1996 was $10.0 million as compared to a net
loss of $2.3 million for the quarter ended September 30, 1995.
 
     EBITDA
 
     EBITDA decreased to ($3.3) million for the three months ended September 30,
1996, from ($1.1) million for the three months ended September 30, 1995, a
decrease of $2.2 million. The decrease reflects the increasing operating and
SG&A expenses noted above resulting from the acquisition, development and
expansion of the Company's networks in order to pursue the opportunities
provided by offering a full array of local exchange services. EBITDA is a
measure commonly used in the telecommunications industry and is presented to
assist in an understanding of the Company's operating results and is not
intended to represent cash flow or results of operations in accordance with
generally accepted accounting principles.
 
NINE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1995
 
     REVENUES
 
     The Company's revenues increased to $28.1 million for the nine months ended
September 30, 1996 from $10.3 million for the nine months ended September 30,
1995, an increase of 173%. These increases reflect the impact of the Company's
acquisition and development activities as well as increased utilization of the
Company's network facilities arising from the sales of additional services to
current and new customers. A significant contributor to the Company's revenue
growth for the nine months ended September 30, 1996 relates to the Company's
entry into local exchange services in Grand Rapids, Michigan as a result of the
City Signal Acquisition. Local exchange services revenues for the nine months
ended September 30, 1996, totaled $4.4 million.
 
                                       37
<PAGE>   40
 
     COSTS AND EXPENSES
 
     Service costs increased to $12.6 million for the nine months ended
September 30, 1996 from $5.2 million for the nine months ended September 30,
1995. Service costs as a percentage of telecommunications services revenues
declined to approximately 45% for the nine months ended September 30, 1996 as
compared to approximately 51% for the nine months ended September 30, 1995.
 
     The Company's SG&A expenses for the nine months ended September 30, 1996
were $25.5 million, as compared with SG&A expenses of $7.8 million for the nine
months ended September 30, 1995. The increase was principally due to the
increasing number and continued expansion of the Company's competitive access
networks, including added personnel costs and marketing activities related to
the introduction of switched services.
 
     Depreciation and amortization expense increased to $9.9 million for the
nine months ended September 30, 1996, from $2.9 million for the nine months
ended September 30, 1995, as a result of the Company's acquisitions and the
continued expansion of the Company's networks.
 
     INTEREST INCOME (EXPENSE)
 
     Interest expense totaling $19.3 million was recorded during the nine months
ended September 30, 1996, as compared to interest expense of $2.8 million for
the nine months ended September 30, 1995. The primary contributor to the
substantial increase in interest expense as compared to the comparable period in
the prior year is non-cash interest expense totaling $15.6 million attributable
to accretion of the 10 7/8% Senior Discount Notes. In addition, capitalized
interest of $1.3 million was recorded for the nine months ended September 30,
1996 related to network construction projects. For the nine months ended
September 30, 1996 and 1995, interest income totaling $11.1 million and
$746,000, respectively, was derived from the Company's available cash and cash
equivalents and marketable securities.
 
     NET LOSS
 
     For the reasons stated above, the Company's net loss before minority
interest increased to $28.0 million for the nine months ended September 30,
1996, from $7.6 million for the nine months ended September 30, 1995. Minority
interests in net losses, representing minority investors' interests in certain
of the Company's subsidiaries, totaled $1.6 million and $589,000 for the nine
months ended September 30, 1996 and 1995, respectively. As a result, the
Company's net loss for the nine months ended September 30, 1996 was $26.4
million as compared to a net loss of $7.0 million for the nine months ended
September 30, 1995.
 
     EBITDA
 
     EBITDA decreased to ($9.9) million for the nine months ended September 30,
1996 from ($2.8) million for the nine months ended September 30, 1995, a
decrease of $7.1 million. The decrease reflects the increasing operating and
SG&A expenses noted above resulting from the acquisition, development and
expansion of the Company's networks in order to pursue the opportunities
provided by offering the full array of local exchange services.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     REVENUE
 
     Telecommunications services revenues grew from $2.8 million in the year
ended December 31, 1994 to $14.2 million ($23.1 million on a pro forma basis
after giving effect to the merger with BTC and the City Signal Acquisition) in
the year ended December 31, 1995. Network capacity as reflected in VGEs in
service increased from 59,208 VGEs as of December 31, 1994 to 122,617 VGEs
(153,073 VGEs on a pro forma basis) as of December 31, 1995. These increases
reflect the impact
 
                                       38
<PAGE>   41
 
of the Company's acquisition and development activities as well as increased
utilization of the Company's network facilities arising from the sales of
additional services to current and new customers.
 
     COSTS AND EXPENSES
 
     Service costs increased from $1.6 million for the year ended December 31,
1994 to $7.2 million for the year ended December 31, 1995. Service costs consist
of costs associated directly with the operation of the Company's competitive
access networks and facilities management services.
 
     Service costs for the year ended December 31, 1995 consist principally of
local and long distance service costs totaling $5.7 million, salaries and
benefits totaling $1.0 million and rights-of-way fees totaling $353,000. Service
costs as a percentage of telecommunications services revenues approximated 55%
for 1994 as compared to approximately 51% for 1995. Due to the fixed nature of
certain costs associated with the development of the Company's competitive
access networks, the Company expects that the ratio of service costs to network
revenues will decline as network usage increases.
 
     The Company's SG&A expenses for the year ended December 31, 1995 were $11.4
million, as compared with SG&A expenses of $4.0 million for 1994. The increase
was principally due to the increasing number and continued expansion of the
Company's competitive access networks and related marketing activities; however,
such costs did not increase to the same degree as the Company's revenues. There
is typically a period of higher SG&A expenses and a lag time in the generation
of revenues following the acquisition and development of a competitive access
network. Management expects SG&A expenses to continue to increase during 1996 as
the Company continues to expand its networks, services and marketing activities.
 
     Depreciation and amortization expense increased from $663,000 for the year
ended December 31, 1994 to $4.1 million for 1995 as a result of the Company's
acquisitions and the continued expansion of the Company's networks.
 
     INTEREST INCOME (EXPENSE)
 
     Interest expense totaling $3.7 million and $693,000 was recorded during
1995 and 1994, respectively, as a result of the incurrence of secured
indebtedness to finance the acquisition and development of certain of the
Company's operations. Under the AT&T Credit Facility, $3.8 million and $135,000
of the interest expense were added to the principal balance during 1995 and
1994, respectively. During the years ended December 31, 1995 and 1994, interest
income totaling $1.6 million and $95,000, respectively, was derived from the
Company's available cash balances.
 
     NET LOSS
 
     For the reasons stated above, the Company's net loss before minority
interest increased from $4.0 million in 1994 to $10.6 million in 1995. Minority
interests in net losses, representing minority investors' interests in certain
of the Company's subsidiaries, totaled $1.1 million and $78,000 for the years
ended December 31,1995 and 1994, respectively. As a result, the Company's net
loss for 1995 was $9.5 million as compared to a net loss of $3.9 million for
1994.
 
     EBITDA
 
     EBITDA decreased from ($2.7) million for the year ended December 31, 1994
to ($4.4) million for the year ended December 31, 1995, a decrease of $1.7
million. The decrease reflects the increasing operating and SG&A expenses noted
above resulting from the acquisition, development and expansion of the Company's
networks. On a pro forma basis, EBITDA for 1995 was ($8.5) million. EBITDA is a

YEAR ENDED DECEMBER 31, 1994 COMPARED TO THE PERIOD FROM NOVEMBER 10, 1993 TO
DECEMBER 31, 1993
 
     The Company commenced operations on November 10, 1993, and it does not
believe that a comparison of results for the period ended December 31, 1993 with
the year ended December 31, 1994 is meaningful.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's total assets increased from $146.6 million as of December 31,
1995 to $637.4 million at September 30, 1996. The Company's current assets of
$346.7 million at September 30, 1996, including cash and cash equivalents and
marketable securities of $329.7 million, exceeded current liabilities of $21.4
million, providing working capital of $325.3 million. Network and equipment
totaled $222.0 million at September 30, 1996 as compared to $53.2 million at
December 31, 1995. Other assets, principally goodwill, net of accumulated
amortization, increased to $74.8 million at September 30, 1996 from $33.5
million at December 31, 1995, primarily as a result of the Company's
acquisitions of both City Signal, Inc. and BTC, and debt issuance costs
associated with the 10 7/8% Senior Discount Note Offering.
 
     In connection with the City Signal Acquisition, the seller received an
option to require the Company to repurchase any or all of the 2,240,000 shares
of the Company's Common Stock issued in the City Signal Acquisition at a price
of $12.50 per share on or before February 1, 1998. In conjunction with the
Company's IPO (see below), ten percent (10%) of such shares were sold.
Accordingly, shares subject to redemption totalled 2,016,000 shares at September
30, 1996.
 
     On February 26, 1996, the Company sold $425.0 million aggregate principal
amount of its 10 7/8% Senior Discount Notes, providing gross proceeds of
approximately $250 million, and proceeds net of underwriting fees of
approximately $241 million. No cash payments of interest are required on the
10 7/8% Senior Discount Notes until September 1, 2001.
 
     On May 2, 1996, the Company sold 7,385,331 shares of the Company's Common
Stock in its IPO at a price of $27.00 per share. Gross proceeds from this
offering totaled approximately $199.4 million and proceeds net of underwriting
discounts and advisory fees and expenses totalled approximately $185.2 million.
 
     In June 1996, the Company and MCImetro entered into an agreement pursuant
to which MCImetro has acquired a minority interest in the Company's Sacramento,
California network and has made an additional investment in the San Jose joint
venture company. In connection with these agreements, MCImetro has made
additional cash investments totaling $8.0 million. In accordance with the
provisions of the agreements between the Company and MCImetro, on October 10,
1996 MCImetro exchanged the agreed value of its investments in subsidiaries of
the Company for 958,720 shares of the Company's Common Stock.
 
     The Company has formed a strategic alliance with World-Net and has invested
a total of $20 million for a 25.5% fully-diluted interest in World-Net, and it
is possible that the Company may commit additional funds in furtherance of this
strategic alliance. World-Net is a privately-held development stage company
founded to form a national ISP network. The Company intends for both companies
to seek ways to work together and provide customer-oriented Internet and
Intranet communications solutions.
 
     Effective in July 1996, the Company acquired 100% of the stock of ALD, a
switchless reseller of long distance services, and Tenant Network Services, Inc.
("TNS"), a wholly-owned subsidiary of ALD which acts as a shared tenant service
provider of telecommunications services, both of which provide their services
primarily to customers in the San Francisco, California area.
 
                                       40
<PAGE>   43
 
     Effective in September 1996, the Company acquired 100% of the stock of
Bittel, a switch-based reseller of long distance services, with such services
provided primarily to customers in the San Francisco and Los Angeles, California
areas.
 
     On October 24, 1996, the Company and MaineCom, a subsidiary of Central
Maine Power Company, entered into a letter of intent to form a joint venture
company, to be owned 60% by the Company and 40% by MaineCom, for the purposes of
constructing, owning, operating and developing networks initially in Portland,
Maine and Nashua and Manchester, New Hampshire, and other markets in Maine and
New Hampshire as may be agreed upon by the Company and MaineCom in the future.
The proposal is subject to the negotiation of definitive agreements approved by
the respective Boards of Directors of the Company and MaineCom.
 
     On November 12, 1996, AT&T Credit exchanged the agreed value of its
investments in certain subsidiaries of the Company made in connection with
certain loans to the Company for an aggregate of 234,260 shares of the Company's
Common Stock.
 
     On November 7, 1996, the Company completed the issuance and sale of $400.0
million aggregate principal amount of the Private Notes, for which the Company
received proceeds net of underwriting discounts of approximately $217.2 million.
The Private Notes rank pari passu with the 10 7/8% Senior Discount Notes and
contain certain covenants substantially the same as the covenants in the 10 7/8%
Senior Discount Notes.
 
     As of September 30, 1996, on a pro forma basis after giving effect to the
Private Note Offering and the conversion of $50 million aggregate principal a
mount of subsidiary secured indebtedness to parent company secured indebtedness
on November 12, 1996, (i) the total amount of outstanding liabilities of the
Company (parent only), including trade payables, would have been approximately
$546.8 million, of which $50 million would have been secured obligations, and
(ii) the total amount of outstanding liabilities of the Company's subsidiaries,
including trade payables, would have been $14.1 million, of which $0.1 million
would have represented secured obligations.
 
     The AT&T Credit Facility currently provides the Company a secured line of
credit totalling $50.0 million which has been used to provide financing for the
acquisition and construction of telecommunications networks and the purchase of
equipment related to the construction and operation of the Company's networks in
cities approved by AT&T Credit on a project basis. The terms of the AT&T Credit
Facility provide for two years of capitalized interest, one year of interest
only payments and a six-year principal and interest payout period thereafter.
Indebtedness under the AT&T Credit Facility is secured by the assets of certain
subsidiaries of the Company and is guaranteed by intermediate subsidiaries of
the Company. The facility is further secured by the stock of such subsidiaries
and such guarantors. The AT&T Credit Facility contains covenants substantially
the same as the covenants in the Senior Discount Notes and also contains
covenants applicable to such subsidiaries and such guarantors which place
certain additional limitations on the ability of such entities to incur
indebtedness, create liens, engage in new businesses, dispose of assets, issue
additional capital stock, and effect mergers and consolidations.
 
     The Bank Credit Facility provides the subsidiary operating the Company's
Tulsa, Oklahoma network the ability to borrow amounts up to $10 million from
time to time prior to June 30, 1997, with a final maturity of all loans no later
than June 30, 2002, with interest only payment through August 31, 1997 and a 4.5
year principal payout period thereafter. The Bank Credit Facility is secured by
the assets and stock of the subsidiary. The loan agreement contains certain
restrictive covenants, including limitations on the ability of the subsidiary to
declare and pay dividends to the Company, to incur additional indebtedness, to
make loans and advances and to engage in transactions with the Company (except
for reimbursement for services rendered on arms-length terms and repayment of up
to $10 million of subordinated debt prior to June 30, 1997 in the absence of a
default under the Bank Credit Facility). The Bank Credit Facility contains
financial covenants, including limitations on the ratios of the subsidiary's
annualized operating cash flow to its outstanding debt, interest expense and
debt service costs and requirements for the maintenance of a
 
                                       41
<PAGE>   44
 
minimum amount of annualized operating cash flow. At September 30, 1996, there
was $100,000 of outstanding indebtedness under the Bank Credit Facility.
 
     The competitive local telecommunications services business is a
capital-intensive business. The Company's operations have required and will
continue to require substantial capital investment for (i) the installation of
electronics for switched services in the Company's operating networks; (ii) the
expansion and improvement of the Company's operating systems, including the
installation of capabilities to provide other enhanced services; and (iii) the
acquisition, design, construction and development of additional networks. For
the nine months ended September 30, 1996 and 1995, the Company made expenditures
for the acquisition, design, construction and development of systems totaling
$137.1 million and $29.2 million, respectively.
 
     In response to the demand initially encountered for its services, the
Company will continue aggressive capital deployment plans for the development
and expansion of its networks to allow for an increased level of demand-driven
capital spending necessary to take full advantage of the opportunities presented
by offering a full array of local exchange services. The Company's revised
network development plans provide for the Company to (i) increase the geographic
reach and robustness of its networks to allow the Company to serve a
significantly higher percentage of the market by extending its networks to serve
most, if not all, of the ILEC's central offices in its markets and (ii) more
rapidly deploy switches with full capabilities for local dial tone and switched
access termination and origination services. The Company's previous estimate of
capital spending during 1996 and 1997 to fund the development and expansion of
the Company's initial 30 networks was $290 million, of which $134.3 million was
spent through September 30, 1996. The Company now estimates that it will invest
an additional $200 million associated with its initial 30 networks to fund these
capital needs during 1997 and 1998. The Company currently intends to use the net
proceeds from the Depositary Shares Offering, together with additional financing
to be obtained in the future, to fund the expansion from 30 to 40 networks by
the end of 1997 as well as to cover the related initial operating losses.
 
     The Company's strategic plan calls for having systems in operation or under
development in a total of 50 cities by the end of 1998, which will require
substantial additional capital. The Company expects its expansion into
additional cities will be accomplished by the acquisition of existing networks
as well as the development of new networks. The Company will continue to
evaluate additional revenue opportunities in its existing markets and, as such
opportunities may develop, the Company plans to make additional capital
investments in its networks that may be required to pursue such opportunities,
such as costs required to extend a network or install additional electronics to
meet specific customer requirements. Due to the number and variability of the
factors which could affect the amount of capital that will be required for such
purposes, the Company cannot provide a reasonable estimate of such additional
capital needs. For example, the size of a particular network to be developed or
acquired and the types of electronics installed can impact significantly the
amount of capital required. Similarly, the potential cost of acquiring
additional networks is not determinable, and it is possible that the Company
could acquire existing networks using a variety of financing alternatives. The
Company expects to meet such additional capital needs with the proceeds from
existing and future credit facilities and other borrowings, and the proceeds
from sales of additional equity securities and joint ventures. The Company's
expectations of required future capital expenditures are based on the Company's
current estimates and the current state and federal regulatory environment.
There can be no assurance that actual expenditures will not be significantly
higher or lower. In addition, there can be no assurance that the Company will be
able to raise or generate sufficient funds to enable it to meet its strategic
objectives or that such funds, if available at all, will be available on a
timely basis or on terms that are acceptable to the Company.

EFFECT OF NEW ACCOUNTING STANDARDS
 
     In March 1995, the Financial Accounting Standards Board (FASB) issued SFAS
No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed of, which will require the Company to review for the
impairment of long-lived assets and certain identifiable intangibles to be held
and used by the Company whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. As of the adoption
date of January 1, 1996, the Company had no long-lived assets considered
impaired and no identifiable intangibles or goodwill related to assets to be
disposed of.
 
     In October 1995, the FASB issued SFAS No. 123, Accounting for Stock-Based
Compensation, which establishes a fair value based method for financial
accounting and reporting for stock-based employee compensation plans. However,
the new standard allows compensation to continue to be measured by using the
intrinsic value based method of accounting prescribed by Accounting Principles
Board Opinion No. 25, Accounting for Stock Issued to Employees, but requires
expanded disclosures. SFAS No. 123 is effective in fiscal year 1996. The Company
has elected to continue to use the intrinsic value based method of accounting.
Accordingly, there will be no effect on the Company's consolidated financial
statements.
 
INFLATION
 
     The Company does not believe that inflation has had a significant impact on
the Company's consolidated operations.

                            BUSINESS OF THE COMPANY
 
OVERVIEW OF THE COMPANY
 
     The Company, founded in November 1993, is a leading full service provider
of competitive local telecommunications services to IXCs, ISPs, wireless
carriers and business, government and institutional end users in selected second
and third tier cities within the United States. The Company is organized as a
holding company with individual operating subsidiaries which focus on specific
market segments. Through its operating subsidiaries, the Company acquires and
constructs its own state-of-the-art digital optical fiber telecommunications
networks and facilities and leases network capacity from others to provide IXCs,
ISPs, wireless carriers and business, government and institutional end users
with an alternative source for a broad array of high quality voice, data and
other telecommunications services. Certain of the Company's subsidiaries located
in California currently provide single source integrated local and long distance
telecommunications services and facilities management for medium and small
businesses utilizing the facilities of other providers. GLA, acquired in the
merger with BTC on January 2, 1996, provides a full range of consulting, network
engineering and construction, strategic planning, infrastructure planning and
design and information system services and solutions for the Company and a wide
variety of other telecommunications providers. The Company believes that its
strategic alliance with World-Net Access, Inc., a company founded to form a
national Internet Service Provider network, will enable the Company to provide
its customers with solutions to their needs for Internet and Intranet
communications services.
 
     The Company's networks are organized to take advantage of ongoing
technological, competitive and regulatory changes. The Company sells its
services primarily to IXCs, ISPs, wireless carriers and business, government and
institutional customers who are high volume users of telecommunications
services. Expenditures by IXCs for access connections to their customers
represent their largest single expense and are estimated by industry sources to
represent as much as 45% of the revenues generated by long distance calls.
Through the deployment of state-of-the-art fiber optic networks and switches,
the Company is able to provide the IXCs served by its networks with high
quality, reliable services at prices less than those the regulated ILECs
currently charge. The Company can expand its capabilities to offer these
services beyond the locations served by its networks by interconnecting its
facilities with the facilities of the ILECs, IXCs and other providers of
telecommunications services.
 
     For financial information regarding the Company, see the financial
statements and related notes listed under "Index to Consolidated Financial
Statements."
 
CORPORATE STRATEGY
 
     The Company's goal is to become the primary full service provider of
competitive local telecommunications services to IXCs, ISPs, wireless carriers
and business, government and institutional end users in selected cities by
offering superior products with excellent customer service at prices below those
charged by the ILECs. The principal elements of the Company's strategy include:
 
          TARGET SECOND AND THIRD TIER MARKETS. The Company believes that
     continuing pro-competitive regulatory changes and the broadening range of
     services that can be offered by CLECs present attractive opportunities for
     new CLEC entrants in second and third tier cities where there are typically
     fewer CLEC competitors than in first tier markets and where the ILECs
     generally have placed a lower priority on installing fiber optic systems
     comparable to those being installed by the Company. As an early entrant in
     selected second and third tier cities, the Company believes it can attain a
     leadership position by securing needed franchises and rights-of-way,
     installing robust state-of-the-art CLEC networks and facilities (i.e.,
     networks which are capable of reaching at least 70% to 80% of identified
     business end users in the market and
 
                                       44
<PAGE>   47
 
     most, if not all, of the ILEC's central offices) and establishing customer
     relationships with IXCs, ISPs, wireless carriers and business, government
     and institutional end users that will enable it to take advantage of the
     attractive potential growth rates for local exchange service revenues in
     those markets.
 
          AGGRESSIVELY PURSUE SWITCHED SERVICES OPPORTUNITY. The
     Telecommunications Act of 1996 mandates that ILECs throughout the U.S.
     enter into arrangements with competitors such as the Company for central
     office collocation and unbundling of local services. The Company believes
     that implementation of these and other pro-competitive policies creates
     favorable opportunities to pursue more aggressively the provision of local
     switched services. The Company has a total of 20 digital telephone switches
     installed in its operating networks and plans to leverage its networks and
     customer relationships by offering local dial tone, switched access
     termination and origination services, centrex and desktop products. The
     Company currently offers such services and products in substantially all of
     its operating networks and expects to offer such services and products in
     all of its operating networks by the end of the second quarter of 1997. See
     "-- Current Products and Services."
 
          EXPAND ENHANCED SERVICE OFFERINGS. Consistent with its strategy of
     aggressively pursuing switched services opportunities, the Company is
     expanding its capabilities to provide enhanced services that complement its
     switch-based services. Such enhanced services include, among others, high
     speed video conferencing, frame relay and ATM-based packet transport
     services and Internet access products. The Company is currently offering
     such services in certain markets and expects to offer such services in all
     of its operating networks by the end of 1997. The Company also plans to
     continue to upgrade and add to its systems and services as technology and
     regulations permit. See "-- Planned Products and Services."
 
          CONTINUE TO BUILD OUT EXISTING SYSTEMS. The Company strives to build a
     sufficient revenue base in each of its systems to generate the cash flow
     necessary to enable it to devote more resources to developing and expanding
     its systems as opposed to funding initial operating losses. As a result of
     favorable regulatory developments and the Company's initial favorable
     experiences with the provision of local switched services, the Company has
     determined to more rapidly develop and expand its systems. Its plans
     include increasing the number of cities served, expansion of its existing
     networks and accelerating the deployment of switches and ILEC central
     office collocations. The Company believes that its access to significant
     capital and technical resources and its ongoing efforts to develop close
     working relationships with its IXC customers (see "-- Build on strategic
     relationships" below) will enable it to more rapidly develop and expand its
     systems, add to its service offerings and establish the strong customer
     relationships necessary to solidify its competitive position in its
     selected markets.
 
          CONTINUE TO INCREASE THE NUMBER OF CITIES SERVED. The Company recently
     achieved its long-stated goal of having systems in operation or under
     construction in a total of 30 cities by the end of 1996. The Company plans
     to have systems in operation or under construction in a total of 40 cities
     by the end of 1997 and a total of 50 cities by the end of 1998. The
     Company's expansion into additional cities is expected to be accomplished
     by the acquisition of existing networks as well as the development of new
     networks. See "Business of the Company -- Network Acquisition, Development
     and Design" and "-- Network Construction." By adding networks, the Company
     believes it can increase revenues and obtain economies of scale in its
     operating costs.
 
          BUILD ON STRATEGIC RELATIONSHIPS. In order to capitalize on the
     competitive dynamics of the changing IXC/ILEC relationships, the Company
     has established close business alliances with major IXCs, including joint
     ventures and preferred vendor relationships. In accordance with this
     strategy, (1) in September 1995, the Company and MCImetro formed a joint
     venture company to operate and expand the Company's existing networks in
     San Jose, California and its environs, and in May and June 1996, the
     Company and MCImetro entered into agreements
 
                                       45
<PAGE>   48
 
     which provide that, until September 30, 2001, the Company will be
     MCImetro's preferred provider of certain local access services in a number
     of the Company's markets and pursuant to which MCImetro acquired a 15%
     interest in the Company's Sacramento, California network for $4.5 million,
     and MCImetro invested an additional $3.5 million in the San Jose joint
     venture company (see "-- Strategic Relationships" below), and (2) in
     December 1995, the Company concluded a national preferred vendor agreement
     with AT&T Communications, pursuant to which the Company expects to become
     AT&T Communications' preferred supplier of local access services in most of
     the Company's markets. The Company believes preferred vendor relationships
     with IXCs provide opportunities to leverage its partners' sales channels
     and market support to sell the Company's products and services and expand
     the Company's potential revenue base. In addition, the Company believes
     that relationships with IXCs facilitate its entry into new markets by
     providing access between the IXCs and their customers. The Company has
     organized a national account marketing organization to manage such
     relationships. The Company believes this marketing effort, along with its
     number of cities served, financial resources and telecommunications
     expertise, position it well to develop and maintain these strategic
     relationships. See "-- Strategic Relationships."
 
          LEVERAGE UPON GLA'S SIGNIFICANT TELECOMMUNICATIONS INFRASTRUCTURE
     CAPABILITIES. GLA, a wholly-owned subsidiary of the Company, offers a full
     range of consulting, management, engineering and information system
     solutions for telecommunications companies. GLA provides a full range of
     network engineering, construction, design and strategic planning services,
     as well as financial and management software products, including
     specifically designed software for billing systems, toll rating, plant
     records and financial applications. GLA's capabilities also serve as an
     internal source for the telecommunications infrastructure support needed
     for the Company's CLEC business.
 
CLEC MARKET POTENTIAL
 
     DEVELOPMENT OF LOCAL EXCHANGE SERVICES. The first CAPs, which were the
predecessors of today's CLECs, were established in the mid-1980's to serve the
increasing demand for telecommunication services by the IXCs and business,
finance, government, education and healthcare entities by providing competitive
alternatives to the ILECs in non-switched special access and private line
services. The deregulation of the U.S. telecommunications industry, rapid
changes in technology and the increasingly information intensive nature of the
U.S. economy have significantly expanded the role of telecommunications for
these entities. Industry sources estimate that voice traffic of such end users
is growing at a rate of approximately seven percent per year, while data
communications are growing at three to five times this rate due to the increase
in computerized transactions processing and video applications, the movement to
distributed data processing, the rise of decentralized management structures and
the growing demand for Internet access services, which require the transmission
of large amounts of information with speed, accuracy and reliability.
 
     The present structure of the telecommunications industry has evolved
largely as a result of increased market demand, deregulation, the implementation
of new technologies and increased competition. The rapid development of fiber
optic and digital electronics technologies has encouraged the growth of cost
effective alternatives to the monopolistic position of the ILECs in many of the
local exchange markets. In particular, the IXCs, which industry sources estimate
may pay as much as 45% of their total revenues in local access charges, have
supported competition in the local exchange markets.
 
     Initially, CAPs were permitted to provide only non-switched special access
and private line services. The FCC's Interconnection Decisions in 1992 and 1993
granted CAPs the right to interconnect their private networks to the ILEC
networks to provide collocated special access and switched access transport
services, which enabled CAPs to access new customers and new markets without
physically expanding their networks.
 
                                       46
<PAGE>   49
 
     The pace of regulatory change in the telecommunications industry has
continued to accelerate with the adoption of the Telecommunications Act of 1996
which provides, among other things, for a national template under which, when
implemented, CLECs will be able to provide competitive services on a more equal
basis with the ILECs by further opening local exchange markets to competition
and pre-empting anti-competitive state laws. The Company believes the following
attributes of the Telecommunications Act of 1996 will have certain positive
effects on the Company's operations:
 
     - Market access. Opening all U.S. markets to local competition.
 
     - Network interconnections. Enabling the Company to more fully interconnect
      its networks with ILECs and other carriers to allow the Company to reach
      customers not physically connected to its own networks in a more cost
      effective manner.
 
     - Number portability. Enabling customers to retain their existing phone
      numbers in the event they choose to switch local service providers. The
      Company considers number portability to be a significant factor which can
      positively influence a customer's decision to purchase service from the
      Company.
 
     - Reciprocal compensation. Ensuring fair and reciprocal rates under which
      other carriers and the Company compensate one another for calls made to
      their customers or, in the alternative, not charge one another for calls
      made by customers from one network to the other. The Company expects such
      reciprocal compensation arrangements to improve its operating margins over
      time.
 
     ENTRY INTO SWITCHED SERVICES. The Company believes that the CLEC business
is positioned for dramatic growth. Of the $32 billion of access fees paid by
IXCs to the ILECs in 1994, CLECs accounted for only $294 million or less than
1%. The Company expects that the entry of the ILECs into the long distance
business will increase these penetration rates as IXCs may seek alternatives to
the ILECs as sources of access to their customers. Most states have taken
regulatory and legislative action to open local communications markets to local
exchange competition and co-carrier status. The Company also expects continuing
pro-competitive regulatory changes, including those mandated by the
Telecommunications Act of 1996, together with increasing customer demand, will
create more opportunities for CLECs to introduce additional services, expand
their networks and address a larger customer base. These changes permit CLECs to
offer local dial tone, centrex, desk top and other enhanced services. The
Company believes that these changes afford CLECs the potential to grow
significantly over the next several years. However, there is no assurance that
such regulatory and other industry trends will continue or that future
regulatory developments will be favorable to CLECs.
 
     Until recently, the Company's capital expenditure programs were directed
primarily toward the construction and acquisition of new networks and the
purchase of related equipment. While the Company intends to continue these
activities, it is also accelerating the expansion of its existing networks,
including more rapid deployment of switches and ILEC central office
interconnections, in order to take advantage of its developing demand-based
opportunities in those networks. Accordingly, the Company has increased the
number of CLEC lines in service from 3,187 at December 31, 1995 (on a pro forma
basis giving effect to the City Signal Acquisition) to 17,914 at November 30,
1996, with annualized CLEC revenues increasing from $2.5 million based on
December 1995 revenues to $10.2 million based on September 1996 revenues.

CURRENT PRODUCTS AND SERVICES
 
     SPECIAL AND SWITCHED ACCESS AND PRIVATE LINE SERVICES. The Company
currently provides several types of special and switched access and private line
services to its IXC and end-user
 
                                       47

customers. Historically, CAPs such as the Company were able to offer only
non-switched special access and private line services which involved the
installation of dedicated lines to provide the following types of communications
links:
 
     - POP-to-POP Special Access -- Telecommunications lines linking the POPs of
      one IXC or the POPs of different IXCs in a market, allowing these POPs to
      exchange transmissions for transport to their final destinations.
 
     - End-User/IXC Special Access -- Telecommunications lines between an end
      user, such as a large business, and the local POP of its selected IXC.
 
     - Private Line -- Telecommunications lines connecting various locations of
      one or more customers' operations, suitable for transmitting voice and
      data traffic internally.
 
     The Interconnection Decisions allowed CAPs to provide a broader range of
services by enabling them to access additional customers through connections
with the ILECs' networks. These services include:
 
     - Collocated Special Access -- A dedicated line carrying switched
      transmissions from the IXC POP, through the ILEC's central office to the
      end user.
 
     - Collocated POP-to-ILEC Switched Access Transport -- A dedicated line
      carrying switched transmissions from the ILEC's central office to an IXC's
      POP.
 
     To provide these services, the Company offers various types of highly
reliable, dedicated fiber optic lines that operate at different speeds and
handle varying amounts of traffic to provide tailor-made solutions to its
customers' needs.
 
     - DS-0 -- A dedicated line service that meets the requirements of everyday
      business communications, with transmission capacity of up to 64 kilobits
      of bandwidth per second (a voice grade equivalent circuit). This service
      offers a basic low capacity dedicated digital channel for connecting
      telephones, fax machines, personal computers and other telecommunications
      equipment.
 
     - DS-1 -- A high speed channel typically linking high volume customer
      locations to IXCs or other customer locations. Used for voice
      transmissions as well as the interconnection of Local Area Networks
      ("LANs"), DS-1 service accommodates transmission speeds of up to 1.544
      megabits per second, the equivalent of 24 voice-grade equivalent circuits.
      The Company offers this high-capacity service for customers who need a
      larger communications pipeline.
 
     - DS-3 -- This service provides a very high capacity digital channel with
      transmission capacity of 45 megabits per second, which is equivalent to 28
      DS-1 circuits or 672 voice grade equivalent circuits. This is a digital
      service used by IXCs for central office connections and by some large
      commercial users to link multiple sites.
 
     SWITCH-BASED SERVICES. The Company has added and is continuing to add
capabilities to provide local dial tone and switched access termination and
origination services to its networks. The Company has installed 20 advanced,
state-of-the-art switches. In addition, pursuant to the City Signal Acquisition
and its acquisition of Bittel, the Company acquired three installed
state-of-the-art switches.
 
     Most states have taken regulatory and legislative action to open local
communications markets to various degrees of local exchange competition and
co-carrier status. The Company has established interconnection arrangements with
ILECs for 26 of its 30 networks. The Company expects that continuing
pro-competitive regulatory changes, including those mandated by the
Telecommunications Act of 1996, together with increasing customer demand, will
create more opportunities to introduce additional services and expand the
Company's networks to address a
 
                                       48
<PAGE>   51
 
larger customer base. See "-- CLEC Market Potential," "-- Planned Products and
Services" and "Regulatory Overview."
 
     CENTREX AND LONG-DISTANCE RESALE. Retail business customers in LATAs served
by the Company's subsidiaries in California can acquire centrex and
long-distance services direct from the Company. The Company's subsidiaries
purchase those services in bulk from the ILEC and the IXCs and provide their
retail customers with a single source of integrated local and long distance
telecommunications services and facilities management at a discount from the
published retail ILEC tariff rates. By using centrex service instead of a
private branch exchange ("PBX") to direct their telecommunications traffic,
customers can avoid the large investment in equipment required and the fixed
costs associated with maintaining a PBX network infrastructure. The Company's
centrex service allows medium to small business customers who lack the size or
resources to support their own PBX to benefit from a sophisticated
telecommunications system. The Company's acquisitions of ALD, TNS and Bittel in
1996 have complemented its long-distance resale services directed to such
customers.
 
     CONSULTING SERVICES. Through GLA, the Company provides a full range of
consulting, management, engineering and information system solutions for
telephone, cable television and power companies, wireless providers and other
telecommunications infrastructure owners and operators in the United States and
elsewhere. GLA significantly expanded its capabilities through the acquisition
of Design Extenders, Inc. in January 1994 and its acquisition of Graphic Data
Solutions, a telecommunications software and mapping firm, in January 1995.
 
     Following is a brief description of the services offered by each of GLA's
divisions:
 
          CONSULTING SERVICES. Provides specialized consulting services to
     telephone, cable television and other telecommunications providers. GLA

PLANNED PRODUCTS AND SERVICES
 
     The Company is expanding its capabilities to provide enhanced services,
such as high speed video conferencing, Internet access, frame relay and
ATM-based packet transport services. The Company is currently offering such
services in certain markets and expects to have such capabilities in all of its
operating networks by the end of 1997. These capabilities will enable the
Company to offer a variety of enhanced services where the transport function is
combined with a specific
 
                                       49
<PAGE>   52
 
application to provide an integrated turnkey solution to its customer's voice,
data and video transmission requirements. These enhanced services include
applications such as LAN-to-LAN interconnect services, packet transport
services, high speed video conferencing, Internet access, frame relay, remote
database access and backup services, and fractional bandwidth services,
utilizing both the Company's networks and switching as well as facilities and
services provided by others. This will enable the Company to provide a customer
with all of its business lines and offer a wide range of switched-based
value-added services, such as directory and operator assistance, audio and video
conferencing, calling cards, 800-numbers, voice mail, Internet access and other
enhanced services.
 
STRATEGIC RELATIONSHIPS
 
     From time to time, the Company has held discussions with other
communications entities concerning the establishment of possible strategic
relationships, including transactions involving preferred vendor relationships
and equity investments in the Company and one or more of its subsidiaries.
 
     Effective September 1995, a subsidiary of the Company formed a
majority-owned joint venture with MCImetro to operate and significantly expand
the Company's existing network in San Jose, California and its environs. The
joint venture company operates the network and provides the Company and MCImetro
with the network services needed for their respective customers.
 
     On May 30, 1996, the Company and MCImetro entered into an amendment to the
Company's master service agreement with MCImetro which provides that, until
September 30, 2001, the Company will be MCImetro's preferred provider of certain
local access services in a number of the Company's markets at a discount to
prevailing optimized ILEC rates for comparable circuits. Under the amended
master service agreement, MCImetro has agreed to purchase from the Company, with
certain provisos, all of MCImetro's required local access in specified markets
for new end-user services (and, at MCImetro's election, existing end user
services), and has given the Company a right of first refusal on a
circuit-by-circuit basis to provide other access services required by MCImetro
in such markets. The Company and MCImetro also entered into a subscription
agreement on June 24, 1996 pursuant to which MCImetro has acquired a 15%
interest in the Company's Sacramento, California network for $4.5 million and
MCImetro has invested an additional $3.5 million in the San Jose joint venture
company. In accordance with the provisions of the agreements between the Company
and MCImetro, on October 10, 1996 MCImetro (i) exchanged the agreed value of its
September 1995 investment in the San Jose network and (ii) exchanged the agreed
value of its June 1996 investments in both networks for an aggregate of 958,720
shares of the Company's Common Stock.
 
     In December 1995, the Company and AT&T Communications signed a national
preferred vendor agreement pursuant to which the Company expects to become AT&T
Communications' preferred supplier of dedicated special access, switched access
transport and switched business and residential line services in most of the
Company's markets. The agreement provides that the Company will provide such
services to AT&T Communications at a discount to the tariffed or published ILEC
rates. The Company is currently providing certain services under the agreement
in 11 markets and expects to add additional services in these markets and to add
additional markets during the balance of 1996. Based on the plans currently
being implemented by the Company and AT&T Communications and the level of
services that the Company currently expects to provide in 1996 pursuant to this
agreement, the Company currently expects that its 1996 revenues from this
national vendor agreement will not exceed 10% of the Company's total revenues
for 1996. The Company's provision of services in any additional markets and
additional services is subject to the mutual agreement of the Company and AT&T
Communications with respect to each market, including satisfactory completion of
network validation tests. As a result, there is no assurance that the national
vendor agreement will be extended to cover additional markets and services. See
"Risk Factors -- Dependence on Business from IXCs."
 
                                       50

     The Company believes that Internet and Intranet products and services
complement the Company's existing telecommunications services and present the
Company with potential revenue opportunities, through both the retention of
existing customers and the addition of new customers. To pursue such
opportunities, on June 25, 1996, the Company formed a strategic alliance with
World-Net, a privately-held development stage company founded to form a national
Internet Service Provider network. The Company has invested a total of $20
million for a 25.5% fully-diluted interest in World-Net, and it is possible that
the Company will decide to commit additional funds in furtherance of this
strategic alliance. The Company intends that both companies will seek ways to
work together to provide customer-oriented Internet and Intranet communications
solutions. The Company plans to develop and offer a wide range of
Internet-related services to users of World-Net's national ISP network,
including various dial-up and dedicated Internet access options.
 
CITIES SERVED
 
     In January 1994, the Company completed its first acquisition, an operating
system in Springfield, Massachusetts and rights of way for the development of
networks in Hartford, Connecticut and Providence, Rhode Island, where networks
have been constructed by the Company and are operational. In October 1994, the
Company acquired an operating system serving Sacramento, a system under
construction in San Jose, and a local and long distance resale operation based
in San Francisco, California that serves small to medium sized businesses in the
San Francisco Bay area. The San Jose network was activated during December 1994
and has been expanded into Sunnyvale and Santa Clara, California. A 37-mile
expansion of the San Jose network is being completed, which will extend the
current 32-mile network into Milpitas and Palo Alto, California. See "--
Strategic Relationships" above.
 
     During 1994, the Company also developed business plans and obtained
right-of-way agreements and the necessary operating rights to construct networks
in Oklahoma City, Oklahoma, and Little Rock, Arkansas. These networks, which
added a total of 46 route miles to the Company's networks, became operational
during the first half of 1995.
 
     During March 1995, the Company acquired the assets of a 105-mile CAP
network in Tulsa, Oklahoma. Also during 1995, the Company commenced the
construction of networks in Bakersfield, Fresno and Stockton, California,
Albuquerque, New Mexico, Knoxville, Tennessee, Jackson, Mississippi, Reno,
Nevada and Tucson, Arizona, all of which are now operational.
 
     Effective January 31, 1996, the Company acquired the business of City
Signal, a CLEC with a 208 mile network in Grand Rapids, Michigan, an operating
network in Lansing, Michigan and networks under construction in Ann Arbor,
Michigan and Toledo, Ohio. Also during 1996, the Company commenced the
construction of networks in White Plains, New York, Stamford, Connecticut,
Kansas City, Missouri, Springfield, Missouri and San Mateo, California, all of
which are expected to be operational by the end of the second quarter of 1997.
 
     Subsidiaries of the Company currently have systems in operation or under
construction in the following cities:

     On October 24, 1996, the Company and MaineCom, a subsidiary of Central
Maine Power Company, entered into a letter of intent to form a joint venture
company, to be owned 60% by the Company and 40% by MaineCom, for the purposes of
constructing, operating and developing networks initially in Portland, Maine and
Nashua and Manchester, New Hampshire and other markets in Maine and New
Hampshire as may be agreed upon in the future. The proposal is subject to the
negotiation of definitive agreements approved by the respective Boards of
Directors of the Company and MaineCom.
 
     The Company believes its regional aggregation strategy will yield economies
of scale in service costs and allow service-affecting decisions to occur closer
to its customers.
 
NETWORK ACQUISITION, DEVELOPMENT AND DESIGN
 
     Before determining to acquire or construct a network in a particular city,
the Company's corporate development staff reviews the demographic, economic,
competitive and telecommunications demand characteristics of the city, including
its location, the concentration of potential business, government and
institutional end user customers, the economic prospects for the area, available
data regarding IXC and end user demand and actual and potential CLEC
competitors. Market demand is estimated on the basis of market research
performed by Company personnel and others, utilizing a variety of data including
estimates of the number of interstate access and intrastate private lines in the
city based primarily on FCC reports and commercial data bases.
 
                                       52
<PAGE>   55
 
     If a particular city targeted for development is deemed to have
sufficiently attractive demographic, economic, competitive and
telecommunications demand characteristics, the Company's network planning and
design personnel design a network targeted to provide access to 70% to 80% of
the identified business, government and institutional end user revenue base, to
the IXC POPs and the ILEC's principal central office(s) in the city, utilizing a
"self-healing" optical fiber ring architecture (build-out to 100% of the
identified end users is not considered to be cost-effective in most cases
because a portion of the demand is located in low density areas). Concurrently,
the Company's corporate development personnel visit the location of the proposed
network to begin discussions with city officials, right-of-way providers, IXCs
and potential end user customers.
 
     Based on the data developed during these preliminary studies and visits, in
connection with either an acquisition or the construction of a network,
including estimates of the costs for fiber optic cable, transmission and other
electronic equipment, engineering, distribution and construction, building
entrance requirements and right-of-way acquisition, the Company develops
detailed financial estimates based on the anticipated demand for the Company's
current services (at present, the financial estimates prepared by the Company
for this purpose generally do not include potential future revenues for certain
enhanced products and services, which the Company plans to offer in all of its
operating networks by the end of 1997; see "-- Planned Products and Services").
If the financial estimates meet or exceed the Company's minimum rate of return
thresholds using a discounted cash flow analysis, the Company's corporate
development personnel prepare a detailed business and financial plan for the
proposed network, including competitive, regulatory and right-of-way analyses.
 
     In the case of acquisitions, Company personnel perform due diligence in
order to determine if the city and network involved meet the foregoing
development and construction criteria. The ability of the Company to acquire
suitable additional systems will be subject to competition for acquisition
candidates.
 
NETWORK CONSTRUCTION
 
     When the Company decides to build a network, the Company's corporate
development staff obtains any needed city authorizations. In some cities, a
construction permit is all that is required. In other cities, a license
agreement or franchise may also be required. Such licenses and franchises are
generally for a term of limited duration. The Telecommunications Act of 1996
requires that local governmental authorities treat telecommunications carriers
in a competitively neutral, non-discriminatory manner. The Company's current
licenses and franchises expire in different years, ranging from 2000 to 2010.
City franchises often require payment of franchise taxes which in some cases can
be included as part of customer charges for use of the network. The Company's
corporate development staff also finalizes arrangements for needed
rights-of-way. The Company strives to obtain rights-of-way on favorable terms
that afford the opportunity to expand the networks as business develops.
Rights-of-way are typically leased under multi-year agreements with renewal
options and are generally non-exclusive. The Company leases underground conduit
and pole space and other rights-of-way from entities such as ILECs and other
utilities, railroads, long distance providers, state highway authorities, local
governments and transit authorities. The Telecommunications Act of 1996 requires
most utilities, including most ILECs and electric companies, to afford CLECs
access to their poles and conduits and rights-of-way at reasonable rates on
non-discriminatory terms and conditions.
 
     The Company's networks are constructed to cost-effectively access areas of
significant end user telecommunications traffic, as well as the POPs of most
IXCs and the principal ILEC central offices in the city. The Company establishes
general requirements for network design which are then provided to an
engineering firm that renders drawings of the contemplated network and the
required deployment. Construction and installation services are provided by
independent contractors selected through a competitive bidding process. Company
personnel provide project management services, including contract negotiation
and supervision of the construction, testing and
 
                                       53
<PAGE>   56
 
certification of all facilities. The construction period for a new network
varies depending upon the number of route miles to be installed, the initial
number of buildings targeted for connection to the network, the general
deployment of the network and other factors. Networks that the Company has
installed to date generally have become operational within four to six months
after the beginning of construction.
 
EQUIPMENT SUPPLY
 
     The Company purchases fiber optic cable and transmission and other
electronic equipment from Lucent Technologies, Inc. (formerly AT&T Network
Systems) and other suppliers at prevailing market prices. The Company expects
that fiber optic cable, equipment and supplies for the construction and
development of its networks will continue to be readily available from Lucent
Technologies, Inc. and other suppliers as required. In August 1995, the Company
entered into an agreement with Lucent Technologies, Inc. under which, as of
September 30, 1996, it has accepted delivery of 14 state-of-the-art 5ESS(@)-2000
switches.
 
CONNECTIONS TO CUSTOMER LOCATIONS
 
     Office buildings are connected by network backbone extensions to one of a
number of physical rings of fiber optic cable, which originate and terminate at
the Company's central node. Signals are sent through a network backbone to the
central node simultaneously on both primary and alternate protection paths. Most
buildings served have a discreet Company presence (referred to as a "remote
node") located in the building. Within each building, Company-owned internal
wiring connects the Company's remote node to the customer premises. Customer
equipment is connected to Company-provided electronic equipment generally
located in the remote node where customer transmissions are digitized, combined
and converted to an optical signal. The traffic is then transmitted through the
network backbone to the Company's central node where originating traffic can be
reconfigured for routing to its ultimate destination on the network.
 
     The Company locates its remote node electronic equipment either in a room
leased from the building owner or on a customer's premises. Leasing space from a
building owner enables the Company to share electronic equipment among multiple
customers, causes little interruption for customers during installation and
maintenance and allows the Company to introduce new services rapidly and at low
incremental cost. For these reasons, the Company believes that leasing or
otherwise controlling equipment rooms in buildings served is desirable and has
therefore chosen to establish such arrangements where possible. When the Company
is unable to lease space from the building owner, the Company generally utilizes
space provided by the customer at no cost to the Company.
 
SALES AND MARKETING
 
     The Company seeks to leverage its networks through sales and marketing
activities targeted at two separate customer groups: wholesale and retail.
Wholesale customers consist of IXCs and information service providers such as
commercial data processing service providers and ISPs. Retail customers are
composed primarily of businesses, government and institutional
telecommunications users that have high volume dedicated telecommunications
requirements and, to a lesser extent, include residential customers for switched
services. Services are offered in accordance with tariffs filed with the FCC for
interstate services and state regulatory authorities for intrastate services.
Since they are classified by the FCC as non-dominant carriers, the Company's
subsidiaries do not have to cost-justify their rates and in certain cases may
enter into customer and product specific arrangements.
 
     WHOLESALE CUSTOMERS. The Company currently targets the major IXCs, such as
AT&T, MCI, Sprint, WorldCom and Frontier, and major information service
providers on a national basis. The Company believes that it can effectively
compete to provide access products (i.e., DS-1, DS-3,
 
                                       54
<PAGE>   57
 
frame relay, ATM and Internet hub servers) to these target customers in the
cities in which it operates based on price, reliability, state-of-the-art
technology, route diversity, ease of ordering and customer service. The Company
provides POP-to-POP and POP-to-end user non-switched access services and
switched access termination and origination services at prices below those the
regulated ILECs currently charge. The Company strives to establish close working
relationships with its IXC customers through "electronic bonding" of its
operations with those of the IXCs. Electronic bonding provides a seamless
integration of the Company's networks with the IXC's network which enables the
IXC to access service, billing and other data direct from the Company's networks
and permits the IXC to enter automated service requests (ASRs) electronically
through the integrated network.
 
     Wholesale customers are currently marketed by national account
representatives since the major IXCs and information service providers have
established national or regional groups to manage and coordinate their
purchasing of access services. These groups assess CLECs not only upon price,
quality, service and ease of provisioning in a particular market, but also upon
size, scope of operations and financial stability in order to maximize the
leverage of their CLEC relationships. The Company focuses on serving its IXC
customers in all of the Company's cities with a view to establishing national
preferred vendor relationships.
 
     For the three months ended September 30, 1996, approximately 21% of the
Company's consolidated revenues were attributable to access services provided to
IXCs pursuant to numerous individual service orders. Approximately 12% of such
consolidated revenues were attributable to services provided to MCI and its
affiliates pursuant to more than 200 individual service orders. The loss of
access revenues from IXCs in general or the loss of MCI as a customer could have
a material adverse effect on the Company's business.
 
     IXC customers typically place individual service orders for specific
circuits for the Company to provide private line or local access services under
master service agreements which do not obligate the customer to any level of
business. Most of such current service orders can be terminated by the customer
on 60 days or less notice, subject, in certain cases, to specified termination
liabilities. However, as indicated above under "-- Strategic Relationships," the
Company has recently entered into a national preferred vendor agreement with
AT&T Communications under which, subject to mutual agreement, the Company
expects to become AT&T Communications' preferred supplier of certain specified
services in certain specified markets, and has recently entered into an
amendment to its master service agreement with MCImetro which provides that,
until September 30, 2001, the Company will be MCImetro's preferred supplier of
local access services in a number of the Company's markets. Information service
providers typically commit to a service agreement for a term of up to three to
five years which is either renegotiated or, with certain contracts,
automatically renewed for successive one-year periods or converted to a
month-to-month arrangement at the end of the contract term. The Company's
wholesale rates are sometimes based on published tariffs, which are subject to
revision from time to time, based upon changes in the published tariffs. The
Company believes that it is well positioned to serve the IXCs and information
service providers and generally has good relationships with its IXC and
information service provider customers.
 
     RETAIL CUSTOMERS. The Company primarily targets four retail customer
segments -- government, finance, health care and education -- all of which have
high volume telecommunications requirements. The Company is currently providing
these customers private line services such as point-to-point communications,
dedicated DS-Os, DS-1s and DS-3s, dedicated high-speed Internet access, local
dial tone and switched access termination and origination services. The Company
is currently introducing frame relay and ATM-based packet transport capabilities
and will have the capability to offer a wide range of switch-based, value added
services, such as directory and operator assistance, audio and video
conferencing, calling cards, 800-numbers, voice mail and enhanced fax, Internet
access and a variety of native speed LAN-to-LAN and FDDI transport services, as
well as high quality video transport. These services provide customers with cost
effective data transmission and access to services such as the Internet.
ATM-based packet
 
                                       55
<PAGE>   58
 
transport capabilities will also provide a vehicle for launching future services
such as ultra high speed data and compressed video transport.
 
     The Company believes that it can effectively compete for business,
government, institutional and other end user customers based upon price,
reliability, product diversity, service and custom solutions to the customer's
needs. The Company offers such services to retail customers at prices below
those currently offered by the regulated ILECs. In addition, the Company's
self-healing optical rings ("SONET") provide reliability which the Company
believes is generally superior to the reliability provided by many of the ILECs
in second and third tier cities.
 
     Retail customers are currently marketed through Company direct sales
representatives in each city. The national sales organization also provides
support for the local sales groups and develops new product offerings and
customized telecommunications applications and solutions which address the
specific requirements of particular customers. In addition, the Company markets
its products through advertisements, trade journals, media relations, direct
mail and participation in trade conferences.
 
     Retail customers typically commit to a service agreement for a term of
three to five years which is either renegotiated or automatically converted to a
month-to-month arrangement at the end of the contract term. Retail contracts are
generally at fixed rates. The Company believes that it has generally good
relationships with its retail customers.
 
     CONSULTING CUSTOMERS. GLA's sales and marketing efforts are directed
towards a wide variety of telephone, cable television and power companies,
wireless providers and other telecommunications infrastructure owners and
operators in the United States and elsewhere. GLA offers multi-faceted solutions
to customers' telecommunications infrastructure requirements utilizing its
varied technical and engineering expertise to offer a complete package of
consulting, field service and information systems support. GLA's engineering and
technical personnel include professionals who have significant technical and
engineering expertise in most of the critical voice, video, data and wireless
telecommunications technologies.
 
NETWORK OPERATIONS
 
     The Company's networks consist of fiber optic digitally-based
communications paths which allow for high-speed, high quality transmission of
voice, data and video communications. The Company typically installs backbone
fiber optic cables containing either 96 or 144 fiber strands, which have
significantly greater bandwidth carrying capacity than traditional analog copper
cables. Using current electronic transmitting devices, a single pair of glass
fibers on the Company's networks can transmit up to 32,256 simultaneous voice
conversations, whereas a typical pair of wires in a traditional analog copper
cable installed in many current ILEC networks can currently carry only a maximum
of 24 simultaneous voice conversations. The Company expects that continuing
developments in compression technology and multiplexing equipment will increase
the capacity of each fiber, thereby providing more bandwidth carrying capacity
at relatively low incremental cost.
 
     The Company offers end-to-end fully protected fiber services utilizing
SONET ring architecture which routes customer traffic simultaneously in both
directions around the ring to provide protection against fiber cuts. Back-up
electronics for high-speed circuits become operational in the event of failure
of the primary components adding further redundancy to the Company's systems.
 
     The Company's networks are monitored seven days per week, 24 hours per day
by the Company's NOC Centers (Network Operations Control Centers) in St. Louis,
Missouri and Grand Rapids, Michigan. The NOC Centers provide a single point of
contact for network monitoring, troubleshooting and dispatching, as well as
capabilities for "electronic bonding" with customers.
 
     With full time monitoring, service problems are detected, diagnosed and, in
most cases, repaired remotely from the NOC Centers, typically before they
adversely affect the Company's
 
                                       56
<PAGE>   59
 
customer and often before the customer even notices a problem. The NOC Centers
provide real-time alarm status and performance information for each of the
Company's networks around the country. They also afford improved disaster
recovery to customers through remote circuit provisioning and cross-connect
features.
 
CORPORATE OFFICE
 
     The Company's principal executive offices are located at 425 Woods Mill
Road South, Suite 300, Town & Country, Missouri 63017, and its telephone number
at those offices is (314) 878-1616.
 
NETWORK FACILITIES AND OFFICES
 
     The Company leases network hub sites and other facility locations and sales
and administrative offices in each of the cities in which it has operations.
During the nine months ended September 30, 1996, rental expense for such
locations and offices totaled $1.5 million. At September 30, 1996, minimum
future rental payments under noncancelable leases covering the Company's
locations and offices totaled $17.1 million. The Company owns a 23 acre parcel
of land in Town & Country, Missouri on which it is constructing its new
corporate headquarters building. A wholly-owned subsidiary of the Company owns a
42,000 square foot office building in Grand Rapids, Michigan that houses a
switch, NOC Center and office facilities.
 
EMPLOYEES
 
     At November 30, 1996, the Company had approximately 776 full-time
employees. None of the Company's employees is represented by a union or covered
by a collective bargaining agreement. The Company believes it has a highly
capable and motivated work force with whom relations are good. In connection
with the construction and maintenance of its fiber optic networks, the Company
uses third-party contractors, some of whose employees may be represented by
unions or covered by collective bargaining agreements.
 
LEGAL PROCEEDINGS
 
     On September 22, 1995, GST Tucson Lightwave, Inc. ("Lightwave") was
permitted to intervene in litigation originally filed by Brooks Fiber
Communications of Tucson, Inc., a wholly-owned subsidiary of the Company ("BFC
Tucson"), styled Brooks Fiber Communications of Tucson, Inc. v. City of Tucson,
cause No. CIV 95-655-TUC-RMB, U.S. District Court, District of Arizona. On
October 2, 1995, Lightwave filed a counterclaim against BFC Tucson, the Company
and Tucson Electric Power Company ("TEP"), charging BFC Tucson, the Company and
TEP with violations of antitrust laws, all of which alleged violations stem from
an agreement between BFC Tucson and TEP that allowed BFC Tucson exclusive
rights, for one year, to utilize certain of TEP's rights of way. The original
causes of action have been settled; however, the counterclaim by Lightwave is
currently still pending. The counterclaim seeks treble damages, attorneys' fees,
costs (all in an unspecified amount) and such other relief as the court deems
proper. The Company believes the claims are without merit and intends to defend
vigorously against this action. The Company believes that resolution of the
matter will not have a material adverse effect on the consolidated financial
condition or results of operations of the Company.
 
     From time to time the Company or a subsidiary of the Company is named as a
defendant in routine lawsuits incidental to its business. Based on the
information currently available, the Company believes that none of such current
proceedings, individually or in the aggregate, will have a material adverse
effect on the Company.

               THE COMPETITIVE LOCAL TELECOMMUNICATIONS INDUSTRY
 
LONG DISTANCE SERVICES
 
     The 1982 court-directed breakup of AT&T (the "Divestiture") specifically
provided for competition in the long distance segment of the market, but
prohibited the RBOCs from entering the inter-LATA long distance market.
Competitors in the long distance market now include AT&T, MCI, Sprint, WorldCom,
Frontier and numerous other smaller inter-exchange carriers. These long distance
carriers provide only the interconnection between local telephone networks and
pay access charges to the ILECs for originating and terminating the calls
carried by the IXC. By 1992, it is estimated that more than one-third of the
nation's long distance market was controlled by competitors of AT&T. Following
the Divestiture, service levels in the long distance market have improved,
product offerings have increased and prices for long distance service generally
have declined, all of which has resulted in increased consumer demand and
significant market growth for long distance services.
 
LOCAL EXCHANGE SERVICES
 
     In contrast to the long distance telecommunications inter-exchange market,
the local exchange market, until recently, has remained the domain of the ILECs
as the result of regulatory policy. ILECs include the seven RBOCs and their 22
Bell operating company subsidiaries ("BOCs"), the GTE operating companies,
United Telecom Corp. and approximately 1,000 other independent local exchange
carriers. It is estimated that 1995 ILEC revenues approximated $102 billion
nationally, including Local Exchange Services. In general, the ILECs connect end
users within a LATA and also provide the local portion of most long distance
calls. The ILECs are required to serve all residential and business users within
restricted geographic areas defined by the LATAs. The market for Local Exchange
Services consists of a number of distinct services and related charges that
include:
 
          1. Switched Local and Private Line Services -- The basic dial tone,
     centrex and private line services;
 
          2. Long Distance Access Services -- The access services provided by
     the ILECs to IXCs for the local origination or termination of long distance
     telephone calls; and
 
          3. Intra-LATA Long Distance Services -- Long distance calls
     originating and terminating within a LATA.
 
     Traditionally, the ILECs' costs of providing certain Switched Local
Services have been subsidized by Long Distance Access Services and Intra-LATA
Long Distance.
 
     The following schematics illustrate the general structure of a CLEC network
and an IXC long distance network.

COMPETITIVE PROVIDERS OF LOCAL EXCHANGE SERVICES
 
     Although the Divestiture did not mandate competition in the local exchange
market, the rapid development of fiber optic and digital electronic technologies
has encouraged the growth of cost effective alternatives to the monopolistic
position of the ILECs in many of the local exchange markets. In addition, the
IXCs have lobbied for competition in the local exchange markets due to the
significant fees paid by IXCs to the ILECs. Industry sources estimate that local
access charges paid by IXCs equal as much as 45% of the long distance industry's
total revenues.
 
     The first CAPs were established in the mid-1980s to provide nonswitched
special access and private line services in direct competition with the ILECs.
Initially, CAPs could compete effectively only for the $8.6 billion special
access and private line services portion of the local exchange market. These
services were provided to customers in buildings physically connected to
separate, privately-owned CAP networks. Within this framework, the CAPs offered
three types of special access and private line services:
 
          1. Special access long distance carrier connections. High capacity
     lines used to transmit telecommunications voice and data between the Points
     of Presence of an IXC or from one IXC to another ("POP to POP-Special
     Access");
 
          2. Special access, end user to IXC connections. Medium to high
     capacity lines to connect business, government and institutional end users
     to IXCs ("POP to End User-Special Access"); and
 
          3. Private line, end user to end user connections. Low to medium
     capacity lines used to interconnect multiple customer locations ("End User
     to End User Private Line").
 
     In September 1992, the FCC ordered the RBOCs and all but one of the larger
ILECs (those having in excess of $100 million in gross annual revenues) to
provide interconnection in the ILECs' central offices to any competitive access
provider seeking such interconnection for the provision of interstate special
access services. The FCC also ordered the ILECs to file interconnection tariffs
by February 1993; these tariffs became effective in June 1993. This decision
granted CLECs the right to interconnect their private networks to the networks
of the ILECs, thereby enabling the CLECs to access new customers and new markets
without physically expanding their networks ("Collocated Special Access").
Initially, the FCC's new rules were restricted to the provision of the $2.5
billion interstate collocated special access services portion of the local
exchange market.
 
     In August 1993, the FCC adopted rules for switched access transport
services, which largely mirror the FCC's special access rules. Switched access
transport is an identical service to special access except that it connects with
a ILEC central office at one end and carries traffic to an IXC POP that has been
switched by the ILEC at the central office. This represents a $4.3 billion
portion of the local exchange market. The FCC ordered the larger ILECs to file
new tariffs reflecting interconnection by CLECs by November 1993; these tariffs
became effective in February 1994 for switched access transport ("Collocated
Switched Access Transport").
 
     In the August 1993 decision, the FCC issued additional rulings concerning
expanded interconnection for competitive access services. First, the FCC
reaffirmed its Special Access Order adopted
 
                                       59
<PAGE>   62
 
in September 1992, in which the FCC ordered the larger ILECs to allow CLECs
interconnection with ILECs for special access. The FCC also reaffirmed its
"Fresh Look" policy which allows certain customers who have entered into
long-term contracts with ILECs for access services to terminate those agreements
with only limited termination charges. This policy is intended to allow local
competitive access providers to penetrate a market more quickly since it permits
end users to move their telecommunications traffic to the competitive provider
with minimal transfer costs.
 
     The FCC also granted ILECs additional pricing flexibility for switched
access services in the form of zone density pricing similar to zone density
pricing allowed for special access interconnection. In addition, the FCC allowed
the local exchange carriers to offer volume discounts and term discounts,
subject to certain limitations.
 
     In total, the FCC's Interconnection Decisions permitted CLECs to compete
for an additional $13.8 billion portion of the local exchange market (including
$7.0 million of switched access termination).
 
     The Telecommunications Act of 1996, which contains provisions that mandate
local and long distance telecommunications services competition, was enacted
into law on February 8, 1996 (see "Regulatory Overview"). The FCC has issued and
will issue further orders under the Telecommunications Act of 1996, many of
which, if not all, will likely be appealed by one or more affected parties to
the U.S. Court of Appeals and U.S. Supreme Court. In addition, the
Telecommunications Act of 1996 may be amended in 1997 or subsequent years.
Therefore, the Company is unable to determine the final form and impact of
existing and future legislation, and the regulatory and judicial actions under
such legislation.
 
     In addition to the federal initiatives and rulings, most states have now
taken regulatory and legislative action to open local telecommunications markets
to local exchange competition and co-carrier status. The Company is deploying
switches on its networks as rapidly as possible and plans to have switches
serving all of its operating networks by the end of the second quarter of 1997.
 
     When the first CAP networks were built in the 1980s, they could compete
effectively only for the approximately $8.6 billion special access and private
line services portion of the local exchange market (POP to POP Special Access,
POP to End User Special Access and End User to End User Private Line). Beginning
in 1994, after the FCC's Interconnection Decisions, which allowed CAPs to
provide Collocated Special Access, Collocated Switched Access Transport and,
with the installation of a switch, Switched Access Termination services, CAPs
were allowed to compete for an additional estimated $13.8 billion portion of the
market. If regulatory and other industry trends continue, the Company believes
that ultimately the entire approximately $102 billion total U.S. market may be
open to competition as CLECs deploy switches capable of providing the full array
of local exchange services and as state public utility commissions ("PUCs")
authorize CLECs to provide full local telecommunications services.

                                  COMPETITION
 
     As noted above, the regulatory environment continues to promote competition
as the FCC has set the industry on an open competition course with its
Interconnection Decisions. Most state regulatory authorities have followed the
FCC's lead by requiring co-carrier status for CLECs and ILEC open network
scenarios. In addition, the Company believes that the recently enacted
Telecommunications Act of 1996 and regulatory and court orders at the federal
level may further accelerate the open competition process.
 
ILECS
 
     In each city served by its networks, the Company faces, and expects to
continue to face, significant competition from the ILECs, which currently
dominate their local telecommunications markets. As competition in the local
exchange market proceeds, the Company believes that a fundamental division
between the needs of business/governmental/institutional end users and
residential end users will drive the creation of differentiated
telecommunications services and service providers. The Company believes that the
IXCs, ISPs, wireless carriers and business, governmental and institutional end
users on which it focuses will have distinct requirements including maximum
reliability, consistent high quality transmissions, capacity for high speed data
transmissions, diverse routing, responsive customer service and continuous
attention to service enhancement and new service development.
 
     The Company competes with the ILECs for these customers in its markets on
the basis of price, reliability, state-of-the-art technology, product offerings,
route diversity, ease of ordering and customer service. However, the ILECs have
long-standing relationships with their customers and provide those customers
with various transmission and switching services that the Company, in some
cases, is not currently allowed by regulators to offer. The Company has sought,
and will continue to seek, to achieve parity with the ILECs in order to become
able to provide a full range of local telecommunications services. The CLEC
industry continues to challenge, before federal and state regulators, many
advantages which exist because of the ILECs' historical status, but there can be
no assurance that the CLEC industry will succeed in these endeavors. See
"Regulatory Overview" for additional information concerning the regulatory
environment in which the Company operates.
 
     Existing competition for private line, special access and local exchange
services is based primarily on quality, capacity and reliability of network
facilities, customer service, response to customer needs, service features and
price, and is not based on any proprietary technology. As a result of the
comparatively recent installation of the Company's fiber optic networks, its
dual path architectures and the state-of-the-art technology used in its
networks, the Company may have cost and service quality advantages over some
currently available ILEC networks. Moreover, because of its customer service
orientation and its focus on business, governmental and institutional customers,
the Company believes that, in general, it provides more attention and
responsiveness to its customers than do its ILEC competitors. The Company also
believes it will be able to successfully compete with the ILECs in the cities
served by its networks because the Company believes the ILECs have generally
been less focused on competition in second and third tier cities and,
accordingly, place a lower priority on replacing their existing copper cable
systems in those cities.
 
     Although the ILECs generally are subject to greater pricing and regulatory
constraints than CLECs, ILECs are achieving increased pricing flexibility for
their services as a result of, among other things, the Interconnection
Decisions. The Telecommunications Act of 1996 also provides further regulatory
flexibility for ILECs to allow them to respond to competition. If the ILECs
continue to lower rates and/or engage in substantial volume and term discount
pricing practices for their customers, there would be downward pressure on
certain rates which the Company charges, which pressure could adversely affect
the Company's profitability. If regulatory decisions permit the ILECs to charge
CLECs substantial fees for interconnection to the ILECs' networks or afford
ILECs other
 
                                       62
<PAGE>   65
 
regulatory relief, such decisions could also have a material adverse effect on
CLECs, including the Company. However, the Company believes this effect will be
more than offset by the increased revenues available as a result of access to
off-net customers provided through interconnection with ILEC networks and the
continuing shift by IXCs to purchasing their access services from CLECs instead
of ILECs.
 
     The Company believes that various legislative initiatives, including the
recently enacted Telecommunications Act of 1996, as well as a recent series of
completed and proposed transactions between ILECs, IXCs and cable companies
increase the likelihood that barriers to local exchange competition will be
removed. The introduction of such competition, however, also means that ILECs
will be authorized to provide long distance services under the provisions of The
Telecommunications Act of 1996. When ILECs are permitted to provide such
services, they will ultimately be in a position to offer single source service.
 
     The entry of ILECs into the long distance business is expected to have a
profound impact on existing market relationships. The Company expects that this
will cause the existing long distance providers to increasingly turn to CLECs to
gain access to their customers.
 
CLECS AND OTHER COMPETITORS
 
     The Company also faces, and expects to continue to face, competition from
other CLECs and other potential competitors in certain of the cities in which
the Company offers its services, some of which competitors have financial,
personnel and other resources substantially greater than those of the Company,
as well as other competitive advantages over the Company. However the Company
believes that, as a result of its strategy to operate in second and third tier
cities, where there are generally fewer CLEC competitors, and to pursue the
establishment of strategic relationships with the major IXCs, combined with its
own capital, technical and management resources, these competitors will not pose
an untenable threat.
 
     In addition to the ILECs and other CLECs, potential competitors capable of
offering private line, special access and local exchange services include long
distance carriers, cable television companies, electric utilities, microwave
carriers, wireless telephone system operators, and private networks built by
large end users. Previous impediments to certain utility companies entering
telecommunications markets under the Public Utility Holding Company Act of 1935
were removed by the Telecommunications Act of 1996.
 
     A continuing trend toward business combinations and alliances in the
telecommunications industry may create significant new competitors to the
Company. MCI announced in January 1994 that its MCImetro unit would invest more
than $2 billion to build in fiber optic rings and local switching equipment in
major metropolitan markets to provide direct connection to its customers and to
provide alternative local telephone services to other IXCs. The recently
announced acquisition of MCI by British Telecommunications could increase the
resources available to MCI for the above purposes. The Company believes that
this affirms the opportunity in the CLEC industry and the Company's decision to
focus on lower tier cities. Since the Company is focusing on different markets,
it does not expect to compete directly against MCImetro in most of its markets,
and it may provide complementary markets to certain MCImetro markets. See
"Business of the Company-Strategic Relationships" for information concerning the
existing and proposed contractual relationships between the Company and
MCImetro. AT&T and Sprint have also indicated their intention to offer local
telecommunications services to certain U.S. markets, either directly or in
conjunction with CLECs or cable operators, and WorldCom and MFS Communications
have recently announced a merger which will enable WorldCom to offer a "one-stop
shopping" combination of long distance and local exchange services.
 
     Cable television companies are upgrading their networks with fiber optics
and installing facilities to provide fully interactive transmission of broadband
voice, video and data communications. Cable company-controlled CLECs, such as
Teleport and U.S. West/Time Warner, historically have
 
                                       63
<PAGE>   66
 
possessed certain advantages over other CLECs in the provision of competitive
access services resulting from certain rights in favor of the cable television
companies to use third-party rights-of-way and to obtain building access at
advantageous costs, and possible cost advantages as a result of
statutorily-prescribed limits on the amounts that electric utilities and ILECs
may charge cable companies for use of utility-owned poles and conduits. However,
the Telecommunications Act of 1996 contains provisions that require most
utilities, including most ILECs and electric companies, to afford CLECs access
to their poles and conduits and rights-of-way at reasonable rates on non-
discriminatory terms and conditions. Recent court decisions invalidating the
FCC's prohibition of cross-ownership of cable companies and telephone companies
in the same local service territory could permit ILECs to compete with cable
television companies in the provision of cable television service in residential
markets. However, the Company believes that the convergence of these industries
will not be a direct threat because their focus is oriented on residential
customers rather than the business customers which the Company targets.
 
     Electric utilities may install fiber optic telecommunications cable to
allow remote meter reading, peak load monitoring, customer service and
interactive billing. The Telecommunications Act of 1996 facilitates the
provision of telecommunications services by electric utilities over those
networks.
 
     Cellular and PCS providers may also be a source of competitive local
telephone service. However, the Company believes wireless operators will be
large users of CLEC access services to transport their calls among their radio
transmitter/receiver sites through networks that avoid the ILECs with whom they
compete.
 
     The Company also competes with equipment vendors and installers, and
telecommunications management companies, with respect to certain portions of its
business.
 
     Many of the Company's existing and potential competitors have financial,
personnel and other resources significantly greater than those of the Company.
However, the Company believes that its strategy of targeting second and third
tier cities, its capital, technical and management resources and its orientation
toward IXCs and other commercial telecommunications users will enable it to
achieve its strategic objectives.

                              REGULATORY OVERVIEW
 
OVERVIEW
 
     The Company's services are subject to varying degrees of federal, state and
local regulation. The FCC exercises jurisdiction over all facilities of, and
services offered by, telecommunications common carriers to the extent those
facilities are used to provide, originate or terminate interstate or
international communications. The state regulatory commissions retain
jurisdiction over the same facilities and services to the extent they are used
to originate or terminate intrastate communications. Local governments sometimes
impose franchise or licensing requirements on CLECs and regulate street opening
and construction activities. The Company actively supports additional regulatory
reform at all levels to further open telecommunications markets to competition.
 
THE TELECOMMUNICATIONS ACT OF 1996
 
     On February 8, 1996, President Clinton signed into law the
Telecommunications Act of 1996, which is comprehensive federal
telecommunications legislation affecting all aspects of the telecommunications
industry. The Telecommunications Act of 1996 establishes a national policy that
promotes local exchange competition. At the heart of the Telecommunications Act
of 1996 is the requirement that local and state barriers to entry into the local
exchange market be removed. The Telecommunications Act of 1996 establishes
uniform standards under which the FCC and state commissions are to implement
local competition and co-carrier arrangements in the local exchange market. The
Telecommunications Act of 1996 also imposes significant obligations on the RBOCs
and other ILECs, including the obligation to interconnect their networks with
the networks of competitors. Each ILEC would be required not only to open its
network but also to unbundle their network elements and services in order that
competitors may purchase only those elements and services that they require. The
pricing of these unbundled network elements and services, which is uncertain and
will depend, among other things, upon regulatory and judicial developments, will
determine whether it is economically attractive for CLECs, IXCs and others to
use these elements and services. ILECs will be required to make available for
resale to new entrants all services they offer end user customers on a retail
basis. The Telecommunications Act of 1996 also imposes requirements on ILECs to
provide reciprocal call termination and telephone number portability.
 
     The Telecommunications Act of 1996 also provides, among other things, that
the RBOCs and other ILECs satisfy a competitive checklist, providing the Company
and other competitors the services and facilities necessary to offer local
switched services. Under the Telecommunications Act of 1996, the FCC is directed
to interpret and clarify these terms. The FCC has engaged in rulemaking
proceedings to establish these arrangements, which will ultimately be
implemented by the state telecommunications or regulatory commissions (see
"State Regulation" below). The following table summarizes the key factors of the
legislatively mandated competitive checklist, often referred to as "co-carrier
status," being pursued by the Company with the FCC and with state regulators and
the anticipated effect of these factors on the Company's ability to provide
fully competitive services on an economically efficient and technically feasible
basis.

</TABLE>
 
     The RBOCs' incentive to comply with the opening under the
Telecommunications Act of 1996 of the local exchange market to competition
derives from the Act's provisions allowing the removal of the current ban on
RBOC provision of interLATA toll service and equipment manufacturing. This ban
will only be removed after the RBOC demonstrates to the FCC, in consultation
with the Department of Justice and the relevant state commissions, that the RBOC
has met the requirements of the competitive checklist, which details the basic
co-carrier requirements, and the FCC concludes that RBOC entry into long
distance is in the public interest. The RBOC must also generally show that it
has entered into an approved interconnection agreement with at least one
unaffiliated, facilities-based competitor in some portion of a state before
offering long distance service in that jurisdiction. In October 1996, Ameritech
filed information with state regulators on the checklist compliance necessary
for it to seek authority to provide inter-LATA long distance service in its
service areas, including Michigan and Ohio, under the Telecommunications Act of
1996.
 
     While state-by-state regulatory activity has to date brought co-carrier
arrangements or initiatives to various degrees of completion in most states, the
Telecommunications Act of 1996 is intended to accelerate the process and create
a competitive environment in all markets, eliminating state and local statutory
and regulatory barriers to entry. This preemption of state laws barring local
competition and the relaxation of regulatory restraints should enhance the
Company's ability to expand its service offerings nationwide.
 
     The Company, as a facilities-based, multi-market competitive provider
already active in emerging co-carrier environments, stands to benefit from the
Telecommunications Act of 1996. In addition to providing the Company with a
national framework to achieve co-carrier status in local exchange markets, the
Telecommunications Act of 1996 permits CLECs with less than 5% of nationwide
prescribed access lines to offer single source combined packages of local and
long distance services. AT&T, MCI and Sprint may not bundle in a RBOC's
territory their local services resold from a RBOC and long distance service
until the RBOC is authorized to enter the inter-LATA long distance market or for
three years, whichever event occurs earlier.
 
                                       66
<PAGE>   69
 
     The Telecommunications Act of 1996, by removing barriers to entry into the
local exchange market and at the same time enabling multiple carriers to compete
with the Company in the provision of telecommunications services, ultimately
allowing the RBOCs and large IXCs to offer their own packages of single source
local/long distance services, substantially increases the competition the
Company will face.
 
     The Telecommunications Act of 1996 also creates a new Federal-State Joint
Board for the purpose of making recommendations to the FCC regarding the
implementation of a largely revised universal service program. All
telecommunications carriers, including the Company, that provide interexchange
services are required to contribute, on an equitable and nondiscriminatory
basis, to the preservation and advancement of universal service pursuant to a
specific and predictable universal service mechanism to be established by the
FCC. The Company is unable to predict the final formulas for universal service
contributions or its own level of contribution.
 
     The Telecommunications Act of 1996 in some sections is self-executing, but
in most cases the FCC must issue regulations that identify specific requirements
before the Company and its competitors can proceed to implement the changes that
the Telecommunications Act of 1996 prescribes. The FCC already has commenced
several of these rulemaking proceedings. In addition, the Telecommunications Act
of 1996 retains for individual state utility commissions authority to impose
their own regulation of local exchange services so long as such regulation is
not inconsistent with the requirements of the Telecommunications Act of 1996.
The Company is unable to predict the final form of such regulation and its
potential impact on the market.
 
FEDERAL REGULATION
 
     The FCC has adopted a "forbearance" policy for non-dominant carriers, such
as the Company and its subsidiaries, under which no prior approval is needed for
network construction or acquisition, and only minimal tariff and reporting
requirements are in effect. In their provision of certain services, ILECs in
most markets are regulated by the FCC as dominant carriers.
 
     As a result of rulings announced in September 1992 and August 1993 (the
"Interconnection Decisions") by the FCC, the Company is able to offer interstate
special access and switched access transport services to virtually every
business and government end user in the metropolitan areas which the Company
elects without being directly connected to such customers. The Interconnection
Decisions enabled CLECs to compete for transport of switched long distance calls
between ILEC central offices and long distance carrier POPs. At the same time
the ILECs were granted greater pricing flexibility for those services. Portions
of the Interconnection Decisions are likely to be further reviewed and addressed
by the FCC as it construes the federal legislation.
 
     In March 1995, a major CLEC introduced an initiative before the FCC calling
for the nationwide unbundling of the "local loops" controlled by the ILECs in
order to make those facilities available on a cost-based basis to all eligible
local service providers, including the Company, following initiation of local
competition. The local loop is the part of the ILEC networks that physically
connects the customer's premises to the central office and is used to receive
and originate local and long distance calls. The Company has simultaneously
pursued similar initiatives before individual state regulatory commissions and
has obtained orders or entered into agreements with ILECs to obtain unbundled
loops in a number of states. The FCC has addressed local loop unbundling and
related unbundling issues in connection with its interpretation of the
Telecommunications Act of 1996.
 
     In July 1995, the FCC took two actions related to the assignment of
telephone numbers, first mandating that over the course of the one year
responsibility for administering and assigning local telephone numbers be
transferred from the RBOCs and a few other ILECs to a neutral entity, and
second, proposing a regulatory structure under which a wide range of number
portability issues would be resolved. The FCC is expected to address those and
other number portability issues in connection with its ongoing interpretation of
the Telecommunications Act of 1996. On July 2, 1996 the FCC issued an order
regarding interim and permanent number portability indicating that rates
 
                                       67
<PAGE>   70
 
charged by ILECs to CLECs for interim portability should be minimal and that
permanent number portability should be available in the top 100 U.S. markets by
the end of 1997. In September 1996, the FCC designated the members of the North
American Numbering Council, which will advise the FCC on numbering issues. On
November 18, 1996, one RBOC filed a complaint in the U.S. Court of Claims
requesting compensation for costs of interim portability that it claims were not
allowed by the FCC in violation of its rights under the Fifth Amendment of the
U.S. Constitution.
 
     In September 1995, the FCC issued a Notice of Proposed Rulemaking which
proposes rules that, among other things, would increase ILEC pricing flexibility
and deregulation as competition increases.
 
     During 1996 the FCC has taken several actions with respect to competitive
local telecommunications pursuant to the Telecommunications Act of 1996.
 
     On August 1, 1996, the FCC issued an order amending its pole attachment
rules to be pursuant to the Telecommunications Act of 1996 by requiring
utilities, including ILECs and most electric companies, to make poles, conduit
and rights-of-way available to telecommunications carriers, including CLECs, at
reasonable cost and on a nondiscriminatory basis. Several utilities have
appealed the FCC order to the U.S. Court of Appeals, which has not yet issued a
decision.
 
     On August 8, 1996, the FCC issued an order containing rules providing
guidance to the ILECs, CLECs, IXCs and state PUCs regarding several provisions
of the Telecommunications Act of 1996, to be applicable in the event that
parties to interconnection agreements cannot agree on certain terms and the
state PUCs issue orders containing arbitrated results.
 
     The rules include, among other things, FCC guidance on: (1) discounts for
end-to-end resale of ILEC local exchange services (which the FCC has suggested
should be in a range of 17% to 25%); (2) availability of unbundled local loops
and other unbundled ILEC network elements; (3) the use of "total element long
run incremental cost" (TELRIC) in the pricing of these unbundled network
elements; (4) average default proxy prices for unbundled local loops in each
state; (5) mutual compensation rates for termination of ILEC/CLEC local calls;
(6) an access charge transition plan that: (a) leaves access charges unchanged
with respect to situations involving resale of ILEC local exchange services; (b)
leaves all access charges in place with respect to situations involving use of
ILEC unbundled switching and other network elements to provide local exchange
services, except for 25% of the "transport interconnection charge" (TIC); and
(c) permits avoidance of access charges only when the ILEC switch is not
utilized; and (7) the ability of CLECs and other interconnectors to opt into
portions of interconnection agreements negotiated by ILECs with other parties on
a most favored nation (or "pick and choose") basis.
 
     The FCC is expected to issue in December 1996 a Notice of Proposed Rule
Making regarding future changes to access charges. In addition, the
Federal-State Joint Board on Universal Service consisting of FCC and state
commissioners made its recommendations on the implementation of the universal
service provisions of the Telecommunications Act of 1996 on November 7, 1996 and
on November 18, 1996 the FCC issued a public notice requesting comments on these
recommendations . Under the Telecommunications Act of 1996, the FCC must act on
these recommendations by May, 1997 and has stated that it intends to announce
new access charge rules within the same time frame.
 
     The Company envisions that the FCC will initiate many additional
proceedings, as a result of the enactment of federal legislation, defining and
construing the terms and conditions of the various components necessary for
local competition. Many, if not all, of the FCC orders under the federal
legislation will likely be appealed by one or more affected parties to the U.S.
Court of Appeals and U.S. Supreme Court. In addition, the Telecommunications Act
of 1996 may be amended in 1997 or subsequent years. Accordingly, the Company is
unable to determine the final form and impact of existing and future
legislation, and the regulatory and judicial actions under such legislation.

COURT APPEALS
 
     Various parties, including ILECs and state PUCs, filed appeals from the
FCC's August 8, 1996 order to various U.S. Courts of Appeal, and several parties
petitioned the FCC and the courts to stay the effectiveness of the FCC rules
included in the FCC's order, pending a ruling on the appeals. Many of the
appeals were transferred to the Eighth Circuit U.S. Court of Appeals. On
November 18, 1996, several members of Congress filed an amicus curiae brief in
support of the appeals of the FCC order.
 
     The FCC has not stayed its own order. However, on October 15, 1996, the
Eighth Circuit U.S. Court of Appeals issued an order containing a partial stay,
pending the court's ruling on the various appeals. The order imposed the partial
stay on: (1) the use of TELRIC in the pricing of unbundled ILEC network elements
and the resulting default proxy prices; and (2) the "pick and choose"
provisions. The remainder of the FCC's August 8, 1996 order remains in effect.
On November 12, 1996, the U.S. Supreme Court declined to overturn the stay. The
Eighth Circuit U.S. Court of Appeals is scheduled to hear arguments on the
various appeals in January 1997.
 
     The partial stay will not have any material adverse effect on the Company
because the Company already has in effect interconnection agreements with the
ILECs, or expects to have such agreements in effect after state PUC
arbitrations, in substantially all of its markets by year-end 1996, under the
provisions of The Telecommunications Act of 1996, which have not been stayed,
and which specifically require ILECs to enter into interconnection agreements
and require state PUCs to arbitrate such agreements within certain time frames.
The stay of the FCC rules does not delay the implementation of the Act by the
parties and by the state PUCs, but rather suspends the guidance that the FCC
sought to provide the parties and the state PUCs in the portions of the rules
that were stayed.
 
STATE REGULATION
 
     The Company's offering of switched local exchange services may be
classified as intrastate and therefore subject to state regulation. The Company
is certified as a CLEC in 26 of its 30 networks. State authorizations vary in
the scope of the intrastate services permitted. The Company is in the process of
seeking to expand the scope of its intrastate certification in various
jurisdictions, a process which will depend upon regulatory action in the
individual states. State laws and regulations that prohibit or have the effect
of prohibiting, local and long distance telecommunications competition are
preempted under the Telecommunications Act of 1996.
 
     In most states, the Company is required to file tariffs setting forth the
terms, conditions and prices for services which are classified as intrastate. In
some states, the Company's tariff can list a range of prices for particular
services, and in others, such prices can be set on an individual customer basis.
The Company is not subject to price cap or to rate of return regulation in any
state in which it currently provides services.
 
     Under the Telecommunications Act of 1996, implementation of the Company's
plans to compete in local markets is and will continue to be, to a certain
extent, controlled by the individual states. The Company continues to support
efforts at the state government level to more quickly implement competition in
their markets under the new federal law and to permit CLECs to operate on the
same basis and with the same rights as the ILECs, sometimes referred to as
"co-carrier status." As of September 30, 1996, most states have taken regulatory
and legislative action to open local communications markets to local exchange
competition and co-carrier status. The Company believes that most of the states
in which it operates will open all local exchange markets to competition in 1996
in accordance with the requirements of the new federal law. When co-carrier
status is granted in a particular state, CLECs would expect to realize lower
costs for providing intrastate switched local exchange services in that state.
 
                                       69
<PAGE>   72
 
     The Company has established interconnection agreements with ILECs for 26 of
its 30 networks. The Telecommunications Act of 1996 requires ILECs to enter into
interconnection agreements with CLECs and other competitors and requires state
PUCs to arbitrate such agreements within certain time frames. US West in New
Mexico is the only RBOC in the Company's operating markets with which the
Company does not have an interconnection agreement, and the Company is in
binding arbitration with US West in New Mexico which is scheduled to be
completed by early 1997. While the Telecommunications Act of 1996 mandates the
implementation of interconnection arrangements, there can be no assurance that
such negotiations will enable the Company to secure its desired co-carrier
arrangements in a timely fashion or for appropriate rates and terms.
 
LOCAL GOVERNMENT AUTHORIZATIONS
 
     In certain locations, the Company is required to obtain local franchises,
licenses or other operating rights and street opening and construction permits
to install and expand its fiber optic networks. In some of the areas where the
Company provides network services, the Company's subsidiaries pay license or
franchise fees based on a percent of gross revenues or on a per linear foot
basis. There is no assurance that certain cities that do not impose fees will
not seek to impose fees, nor is there any assurance that, following the
expiration of existing franchises, fees will remain at their current levels.
 
     The Telecommunications Act of 1996 prohibits local governmental authorities
from discriminating among telecommunications carriers and mandates competitively
neutral treatment.

terminated prior to its expiration date and the Company were forced to remove

     1996 EMPLOYEE STOCK PURCHASE PLAN. In February 1996, the Company
established an Employee Stock Purchase Plan (the "ESPP") to provide employees of
the Company with an opportunity to purchase Common Stock through payroll
deductions. Under the ESPP, up to 500,000 shares of Common Stock have been
reserved for issuance, subject to certain antidilution adjustments. The ESPP
became effective at the time of the Company's initial public offering of Common
Stock in May 1996. The ESPP is intended to qualify as an employee stock purchase
plan within the meaning of Section 423 of the Internal Revenue Code. The first
offering period under the ESPP is from May 1996 through April 30, 1997. The
Board of Directors will have authority to authorize up to four annual offering
periods thereafter. The ESPP terminates on April 30, 2001. Eligible employees
may participate in the ESPP by authorizing payroll deductions during an offering
period within a percentage range determined by the Board of Directors.
Initially, the amount of authorized payroll deductions will be not less than 1%
nor more than 10% of an employee's cash compensation during an offering period,
but not more than $25,000 per year. Amounts withheld from payroll are applied at
the end of each offering period to purchase shares of Common Stock. Participants
may withdraw their contributions at any time before stock is purchased, and in
the event of withdrawal such contributions will be returned to the participants
with interest. The purchase price of the Common Stock is equal to 85% of the
lower of (i) the market price of Common Stock immediately before the beginning
of the applicable offering period or (ii) the market price of Common Stock at
the end of each offering period. All expenses incurred in connection with the
implementation and administration of the ESPP will be paid by the Company.
 
     401(K) PLAN. The Company has a 401(k) savings and retirement plan (the
"401(k) Plan") which covers substantially all employees of the Company. All
employees of the Company who are 21 years of age or older are eligible to
participate in the 401(k) Plan upon completion of twelve months of service. The
401(k) Plan allows participants to agree to certain salary deferrals which the
Company allocates to the participant's plan account. These amounts may not
exceed statutorily mandated annual limits set forth in Sections 401(k), 404 and
415 of the Internal Revenue Code. Participants are also eligible to receive
Company matching contributions each year in an amount up to 50% of the
participant's contribution up to a maximum of 4% of such participant's annual
compensation. All contributions to a participant's plan account are subject to
limitations imposed on retirement plans generally and 401(k) plans in
particular. The Company's contributions will generally vest over a five-year
period. Distribution of a participant's account under the 401(k) Plan may be
made at retirement, death, permanent disability or other termination of
employment in a lump-sum form of payment. Participant's may withdraw amounts
from their plan accounts after attainment of age 59 1/2 or in the event of
proven financial hardship, and may also take loans against their plan account
balances.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     The Company was founded in November 1993 by BTC, executives and other
employees of BTC and the Company and a group of venture capital investors who
provided its initial $40.8 million of equity capital. As the Company's founding
shareholder, BTC received 1,162,800 founder's shares of the Company's Common
Stock and founder's warrants exercisable at $220.00 per share to purchase 81,600
shares of the Company's Series A-1 Convertible Preferred Stock (representing
1,632,000 shares of Common Stock on an as-converted basis at $11.00 per share).
BTC also invested $635,000 in the Company's first round financing to acquire
6,350 shares of the Company's Series A-1 Convertible Preferred Stock and
$1,000,065 in the Company's second round financing to acquire 6,061 shares of
Series A-2 Convertible Preferred Stock. On a fully diluted basis, these
securities represented a total of approximately 14.2% of the Company's capital
stock outstanding on January 2, 1996.
 
     Pursuant to an Agreement and Plan of Merger dated December 19, 1995 between
BTC and the Company, BTC was merged into the Company on January 2, 1996,
securities of the Company held by BTC were cancelled and the former holders of
BTC's Common Stock, BTC's Preferred Stock, Convertible Notes, and options and
warrants to purchase BTC Common Stock received shares of the Company's Common
Stock, warrants to purchase shares of the Company's Series A-1 Convertible
Preferred Stock ("Preferred Stock Warrants") and in-the-money options and
warrants to purchase shares of the Company's Common Stock which, at January 2,
1996, represented an aggregate of approximately 18.5% of the fully diluted
shares of Common Stock of the Company, and out-of-the-money warrants to acquire
an additional 3.3% of the Company's fully diluted Common Stock on such date.
Certain of the executive officers, directors and stockholders of the Company
named in tables under "Principal Stockholders" above were also executive
officers, directors and/or stockholders of BTC prior to the merger and received,
as a result of the merger, an aggregate of 690,720 shares of the Company's
Common Stock, Preferred Stock Warrants exercisable on an as converted basis for
520,100 shares of the Company's Common Stock, 164,760 in-the-money Common Stock
options, 55,540 in-the-money Common Stock warrants and 117,320 out-of-the-money
Common Stock warrants, including approximately 149,280 shares of the Company's
Common Stock and Preferred Stock Warrants exercisable on an as converted basis
for approximately 115,400 shares of the Company's Common Stock in exchange for
an aggregate of 94,106 shares of BTC Common Stock acquired since January 1, 1994
for a total of $2,579,261. See "Management" and "Principal Stockholders."
 
     The terms of the merger reflected an agreed value for the Company's Common
Stock of $12.50 per share (as adjusted for the 20 for 1 Common Stock split
effected concurrently with the merger). The transactional value was mutually
determined by the Company and BTC after consultation with their respective
financial advisors. At a valuation of $12.50 per share, BTC's holdings of the
Company's securities were valued at $22.6 million (accounting for approximately
60% of BTC's total value) and BTC's other assets, comprised primarily of the GLA
consulting business, were valued at approximately $13.8 million. At a price of
$12.50 per share, BTC's fully diluted equity was valued at approximately $36.4
million. In exchange for all of the outstanding securities of BTC, the Company
issued 2,167,360 shares of the Company's Common Stock (representing 756,340
incremental shares) valued at approximately $27.1 million, 81,597 Preferred
Stock Warrants valued at approximately $5.0 million, 375,860 in-the-money Common
Stock warrants and options, and 758,980 out-of-the-money Common Stock warrants.
 
     Pursuant to the terms of a Management and Services Agreement dated November
10, 1993 between the Company and BTC (which was cancelled upon effectiveness of
the merger), BTC had assigned and made available to the Company the services of
the Company's Chief Executive Officer on an as-needed basis and the services of
BTC's Chief Executive Officer to act as Chairman of the Board of the Company,
and had provided, at BTC's principal executive offices, sufficient office space
and support services for the Company's principal executive offices, for a fee of
$250,000 per annum, plus the Company's proportionate share of rent, utilities
and telephone expenses. Pursuant
 
                                       82
<PAGE>   85
 
to a Consulting Agreement, GLA provided network engineering, design and other
services to the Company. During the year ended December 31, 1995, the Company
paid BTC and GLA a total of $1,478,000 pursuant to such arrangements.
 
     Pursuant to the terms of a Management and Services Agreement dated as of
January 2, 1996 between the Company and Brooks Telecommunications International,
Inc. ("BTI", a company spun-off to the stockholders of BTC prior to its merger
with the Company), the Company had agreed to assign and make available to BTI,
on a part-time, as needed basis, the services of its Chairman to act as Chairman
and Chief Executive Officer of BTI and to provide to BTI sufficient office space
and support services to conduct its business, for a fee of $150,000 per annum
plus BTI's proportionate share of rent, utilities, telephone and other
out-of-pocket expenses. The agreement was terminated effective August 31, 1996.
 
     Centennial IV and CHI are investors in World-Net and have invested a total
of $13.3 million for a 20.1% fully diluted interest in World-Net. G. Jackson
Tankersley, Jr. is an individual General Partner of the sole General Partner of
Centennial IV and an executive officer and director of CHI.
 
     As a result of the City Signal Acquisition, Ronald H. Vander Pol received
2,240,000 shares of the Company's Common Stock. In connection with the Company's
IPO, 224,000 of such shares were sold. Mr. Vander Pol has the option to require
the Company to repurchase any or all of the remaining 2,016,000 shares at a
price of $12.50 per share on or before February 1, 1998.
 
     In March 1995, the Company paid to Whitko & Company, an investment banking
and management consulting firm of which Carol deB. Whitaker is chairman, a fee
of $292,000 for consulting services provided to the Company in connection with
the acquisition of certain assets by the Company. No continuing consulting
relationship exists between Whitko & Company and the Company. The Company
believes that the terms and conditions of such services were no less favorable
to the Company than those that would have been available to the Company in
comparable, arm's-length relationships with unaffiliated persons.

                            DESCRIPTION OF THE NOTES
 
     The Private Notes were, and the Exchange Notes will be, issued under that
certain indenture (the "Indenture") dated as of November 7, 1996 between the
Company and The Bank of New York, as Trustee (the "Trustee"). The following
summary of certain provisions of the Indenture does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, the Trust
Indenture Act of 1939, as amended (the "TIA"), and to all of the provisions of
the Indenture, including the definitions of certain terms therein and those
terms made a part of the Indenture by reference to the TIA as in effect on the
date of the Indenture. The Indenture is by its terms subject to and governed by
the TIA. Unless otherwise indicated, references under this caption to sections,
"sec." or articles are references to the Indenture. A copy of the form of
Indenture may be obtained from the Company or the Initial Purchasers. The
definitions of certain capitalized terms used in the following summary are set
forth below under "-- Certain Definitions".
 
GENERAL
 
     The Notes are senior unsecured obligations of the Company and are and will
be issued in fully registered form only, without coupons, in denominations of
$1,000 and integral multiples thereof and will mature on November 1, 2006.
Initially, the Trustee will act as paying agent and registrar for the Notes. The
Notes may be presented for registration of transfer and exchange at the offices
of the registrar, which initially will be the Trustee's corporate trust office.
The Company may change any paying agent and registrar without notice to the
holders of the Notes. The Company will pay principal (and premium, if any) on
the Notes at the Trustee's corporate office in New York, New York. At the
Company's option, interest may be paid at the Trustee's corporate trust office
or by check mailed to the registered addresses of holders of the Notes. Any
notes that remain outstanding after the completion of the Exchange Offer,
together with the Exchange Notes issued in connection with the Exchange Offer,
will be treated as a single class of securities under the Indenture. (sec.sec.
301, 307 and 310)
 
     Principal of and premium, if any, and interest on the Notes will be
payable, and the Notes may be presented for registration of transfer and
exchange, at the office or agency of the Company maintained for that purpose in
the Borough of Manhattan, the City of New York provided that at the option of
the Company, payment of interest on the Notes may be made by check mailed to the
address of the Person entitled thereto as it appears in the Note Register. Until
otherwise designated by the Company, such office or agency will be the corporate
trust office of the Trustee, as Paying Agent and Registrar. (sec.sec. 301, 305
and 1002)
 
     The Notes are issued only in fully registered form, without coupons, in
denominations of $250,000 and any integral multiples of $1,000 in excess
thereof. (sec. 302) No service charge will be made for any registration of
transfer or exchange of Notes, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. (sec. 305)
 
RANKING
 
     The Notes are senior unsecured obligations of the Company, rank pari passu
in right of payment with all existing and future senior unsecured obligations of
the Company at the parent level and rank senior in right of payment to all
future subordinated obligations of the Company at the parent level. Holders of
secured obligations of the Company, however, will have claims that are prior to
the claims of the holders of the Notes with respect to the assets securing such
other obligations.
 
     The Company's principal operations are conducted through its Subsidiaries
and, therefore, the Company is dependent upon the cash flow of its Subsidiaries
to meet its obligations. The Company's Subsidiaries will have no obligation to
guarantee or otherwise pay amounts due under the Notes. Therefore, the Notes
will be effectively subordinated to all indebtedness and other liabilities and
commitments (including trade payables) of the Company's Subsidiaries (including
 
                                       84
<PAGE>   87
 
obligations under the AT&T Credit Facility and the Bank Credit Facility). Any
right of the Company to receive assets of any of its Subsidiaries upon any
liquidation or reorganization of such Subsidiary (and the consequent right of
holders of the notes to participate in those assets) will be effectively
subordinated to the claims of the Subsidiary's creditors, except to the extent
that the Company is itself recognized as a creditor of the Subsidiary. Any
recognized claims of the Company as a creditor of the Subsidiary would be
subordinate to any prior security interest held by any other creditor of the
Subsidiary and obligations of the Subsidiary that are senior to those owing to
the Company.
 
     As of September 30, 1996, on a pro forma basis after giving effect to the
Private Note Offering and the conversion of $50 million aggregate principal
amount of subsidiary secured indebtedness to parent company secured indebtedness
on November 12, 1996, (i) the total amount of outstanding liabilities of the
Company (parent only), including trade payables, would have been approximately
$546.8 million, of which $50 million would have been secured obligations, and
(ii) the total amount of outstanding liabilities of the Company's subsidiaries
including trade payables, would have been $14.1 million, of which $0.1 million
would have represented secured obligations. See "Description of Other Credit
Facilities" and "Pro Forma Combined Consolidated Financial Information."
 
FORM, DENOMINATION AND BOOK-ENTRY PROCEDURES
 
     Exchange Notes issued in exchange for the Private Notes currently
represented by one or more fully registered global notes will be represented by
one or more fully registered global notes (collectively, the "Global Note"), and
will be deposited upon issuance with the Depository and registered in the name
of the Depository or a nominee of the Depository (the "Global Note Registered
Owner"). Except as set forth below, the Global Note may be transferred, in whole
and not in part, only to another nominee of the Depository or to a successor of
the Depository or its nominee.
 
     Exchange Notes issued in exchange for other Private Notes will be issued in
registered, certificated form without interest coupons.
 
     The Depository has advised the Company that the Depository is a
limited-purpose trust company created to hold securities for its participating
organizations (collectively, the "Participants") and to facilitate the clearance
and settlement of transactions in those securities between Participants through
electronic book-entry changes in the accounts of its Participants. The
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations. Access to the
Depository's system is also available to other entities such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly (collectively,
the "Indirect Participants"). Persons who are not Participants or Indirect
Participants may beneficially own securities held by or on behalf of the
Depository only through the Participants or the Indirect Participants. The
ownership interests and transfer of ownership interests of such persons held by
or on behalf of the Depository are recorded on the records of the Participants
and Indirect Participants.
 
     The Depository has also advised the Company that pursuant to procedures
established by it, (i) upon deposit of the Global Note, the Depository will
credit the accounts of its Participants with portions of the principal amount of
the Global Note representing the Exchange Notes issued in exchange for the
Private Notes which each such Participant has instructed the Depository to
surrender for exchange and (ii) ownership of such interests in the Global Note
will be shown on, and the transfer of ownership thereof will be effected only
through, records maintained by the Depository (with respect to the Participants)
or by the Participants and the Indirect Participants (with respect to other
owners of beneficial interests in the Global Note).
 
     Except as described below, owners of interests in the Global Note will not
have Notes registered in their names, will not receive physical delivery of
Notes in definitive form and will not be considered the registered owners or
holders thereof under the Indenture for any purpose.
 
                                       85
<PAGE>   88
 
     Under the terms of the Indenture, the Company and the Trustee will treat
the persons in whose names the Notes, including the Global Note, are registered
as the owners thereof for the purpose of receiving payments in respect of the
principal of and premium, if any, and interest on any Notes and for any and all
other purposes whatsoever. Payments on any Notes registered in the name of the
Global Note Registered Owner will be payable by the Trustee to the Global Note
Registered Owner in its capacity as the registered holder under the Indenture.
Consequently, neither the Company, the Trustee nor any agent of the Company or
the Trustee has or will have any responsibility or liability for (i) any aspect
of the Depository's records or the records of any Participant or Indirect
Participant relating to or payments made on account of beneficial ownership
interests in the Global Note, or for maintaining, supervising or reviewing any
of the Depository's records or records of any Participant or Indirect
Participant relating to the beneficial ownership interests in the Global Note or
(ii) any other matter relating to the actions and practices of the Depository or
any of its Participants or Indirect Participants. The Depository has advised the
Company that its current practice, upon receipt of any payment in respect of
securities such as the Notes (including principal and interest), is to credit
the accounts of the relevant Participants with the payment on the payment date,
in amounts proportionate to their respective holdings in principal amount of
beneficial interests in the relevant security as shown on the records of the
Depository unless the Depository has reason to believe it will not receive
payment on such payment date. Payments by the Participants and the Indirect
Participants to the beneficial owners of Notes will be governed by standing
instructions and customary practices and will be the responsibility of the
Participants or the Indirect Participants and will not be the responsibility of
the Depository, the Trustee or the Company. Neither the Company nor the Trustee
will be liable for any delay by the Depository or any of its Participants or
Indirect Participants in identifying the beneficial owners of the Notes, and the
Company and the Trustee may conclusively rely on and will be protected in
relying on instructions from the Global Note Registered Owner for all purposes.
 
     The Global Note is exchangeable for definitive Notes in registered
certificated form if (i) the Depository (x) notifies the Company that it is
unwilling or unable to continue as Depository for the Global Note and fails to
appoint a successor Depository or (y) has ceased to be a clearing agency
registered under the Exchange Act, (ii) the Company, at its option, notifies the
Trustee in writing that it elects to cause the issuance of the Notes in
definitive registered certificated form, (iii) there shall have occurred and be
continuing an Event of Default or any event which after notice or lapse of time
or both would be an Event of Default with respect to the Notes or (iv) as
provided in the following paragraph. Such definitive Notes shall be registered
in the names of the owners of the beneficial interests in the Global Note as
provided by the Participants. Notes issued in definitive registered certificated
form will be in fully registered form, without coupons, in minimum denominations
of $250,000 and integral multiples of $1,000 above that amount. Upon issuance of
Notes in definitive registered certificated form, the Trustee is required to
register the Notes in the name of, and cause the Notes to be delivered to, the
person or persons (or the nominee(s) thereof) identified as beneficial owners as
the Depository shall direct.
 
     A Note in definitive registered certificated form will be issued upon the
resale, pledge or other transfer of any Note or interest therein to any person
or entity that does not participate in the Depository.
 
     The information in this section concerning the Depository and the
Depository's book-entry system has been obtained from sources that the Company
believes to be reliable, but the Company takes no responsibility for the
accuracy thereof.
 
OPTIONAL REDEMPTION
 
     The Notes will be subject to redemption, at the option of the Company, in
whole or in part, at any time on or after November 1, 2001 and prior to
maturity, upon not less than 30 nor more than 60 days' notice mailed to each
holder of Notes to be redeemed at such holder's address appearing in the Note
Register, in amounts of $1,000 or an integral multiple of $1,000, at the

     The Notes are redeemable prior to November 1, 2001 only in the event that
the Company receives net proceeds from the sale of its Common Stock in a
Strategic Equity Investment on or before November 1, 1999, in which case the
Company may, at its option, use all or a portion of any such net proceeds to
redeem Notes in a principal amount of up to an aggregate amount equal to 33 1/3%
of the original principal amount of the Notes, provided, however, that Notes in
an amount equal to at least 66 2/3% of the original principal amount of the
Notes remain outstanding after such redemption. Such redemption must occur on a
Redemption Date within 75 days of such sale and upon not less than 30 nor more
than 60 days' notice mailed to each holder of Notes to be redeemed at such
holder's address appearing in the Note Register, in amounts of $1,000 or an
integral multiple of $1,000 at a redemption price of 111.875% of the Accreted
Value of the Notes to but excluding the Redemption Date.
 
     If less than all the Notes are to be redeemed, the Trustee shall select, in
such manner as it shall deem fair and appropriate, the particular Notes to be
redeemed or any portion thereof that is an integral multiple of $1,000. (sec.
1104)
 
     The Notes will not have the benefit of any sinking fund.
 
COVENANTS
 
     The Indenture contains, among others, the following covenants:
 
     LIMITATION ON CONSOLIDATED DEBT
 
     The Company may not, and may not permit any Subsidiary of the Company to,
incur any Debt unless either (a) the ratio of (i) the aggregate consolidated
principal amount of Debt of the Company outstanding as of the most recent
available quarterly or annual balance sheet, after giving pro forma effect to
the Incurrence of such Debt and any other Debt Incurred since such balance sheet
date and the receipt and application of the proceeds thereof, to (ii)
Consolidated Cash Flow Available for Fixed Charges for the four full fiscal
quarters next preceding the Incurrence of such Debt for which consolidated
financial statements are available, determined on a pro forma basis as if any
such Debt had been Incurred and the proceeds thereof had been applied at the
beginning of such four fiscal quarters, would be less than 5.5 to 1.0 for such
four-quarter periods ending on or prior to December 31, 1999 and 5.0 to 1.0 for
such periods ending thereafter, or (b) the Company's Consolidated Capital Ratio
as of the most recent available quarterly or annual balance sheet, after giving
pro forma effect to the Incurrence of such Debt and any other Debt Incurred
since such balance sheet date and the receipt and application of the proceeds
thereof, is less than 2.0 to 1.0.
 
                                       87
<PAGE>   90
 
     Notwithstanding the foregoing limitation, the Company and any Subsidiary
may Incur the following:
 
          (i) Debt under Secured Credit Facilities in an aggregate principal
     amount at any one time not to exceed $160 million, and any renewal,
     extension, refinancing or refunding thereof in an amount which, together
     with any principal amount remaining outstanding or available under all
     Secured Credit Facilities, does not exceed the aggregate principal amount
     outstanding or available under all Secured Credit Facilities immediately
     prior to such renewal, extension, refinancing or refunding;
 
          (ii) Purchase Money Debt, which is incurred for the construction,
     acquisition and improvement of Telecommunications Assets, provided that the
     amount of such Purchase Money Debt does not exceed 80% of the cost of the
     construction, acquisition or improvement of the applicable
     Telecommunications Assets;
 
          (iii) Debt owed by the Company to any Wholly-Owned Subsidiary of the
     Company or Debt owed by a Subsidiary of the Company to the Company or a
     Wholly-Owned Subsidiary of the Company; provided, however, that upon either
     (x) the transfer or other disposition by such Wholly-Owned Subsidiary or
     the Company of any Debt so permitted to a Person other than the Company or
     another Wholly-Owned Subsidiary of the Company or (y) the issuance (other
     than directors' qualifying shares), sale, lease, transfer or other
     disposition of shares of Capital Stock (including by consolidation or
     merger) of such Wholly-Owned Subsidiary to a Person other than the Company
     or another such Wholly-Owned Subsidiary, the provisions of this clause
     (iii) shall no longer be applicable to such Debt and such Debt shall be
     deemed to have been Incurred at the time of such transfer or other
     disposition;
 
          (iv) Debt Incurred to renew, extend, refinance or refund (each, a

     accrued interest on the Debt so refinanced plus the amount of any premium
     required to be paid in connection with such refinancing pursuant to the
     terms of the Debt so refinanced or the amount of any premium reasonably
     determined by the Company as necessary to accomplish such refinancing by
     means of a tender offer or privately negotiated repurchase, plus the
     expenses of the Company incurred in connection with such refinancing;
     provided, however, that Debt the proceeds of which are used to refinance
     the Notes or Debt which is pari passu to the Notes or Debt which is
     subordinate in right of payment to the Notes shall only be permitted if (A)
     in the case of any refinancing of the Notes or Debt which is pari passu to
     the Notes, the refinancing Debt is made pari passu to the Notes or
     constitutes Subordinated Debt, and, in the case of any refinancing of
     Subordinated Debt, the refinancing Debt constitutes Subordinated Debt and
     (B) in any case, the refinancing Debt by its terms, or by the terms of any
     agreement or instrument pursuant to which such Debt is issued, (x) does not
     provide for payments of principal of such Debt at stated maturity or by way
     of a sinking fund applicable thereto or by way of any mandatory redemption,
     defeasance, retirement or repurchase thereof by the Company (including any
     redemption, retirement or repurchase which is contingent upon events or
     circumstances, but excluding any retirement required by virtue of the
     acceleration of any payment with respect to such Debt upon any event of
     default thereunder), in each case prior to the time the same are required
     by the terms of the Debt being refinanced and (y) does not permit
     redemption or other retirement (including pursuant to an offer to purchase
     made by the Company) of such Debt at the option of the holder thereof prior
     to the time the same are required by the terms of the Debt being
     refinanced, other than a redemption or other retirement at the option of
     the holder of such Debt (including pursuant to an offer to purchase made by
     the Company) which is conditioned upon a change of control pursuant to
     provisions substantially similar to those described under "Change of
     Control";
 
          (v) Debt consisting of Permitted Interest Rate and Currency Protection
     Agreements; and
 
                                       88
<PAGE>   91
 
          (vi) Debt not otherwise permitted to be Incurred pursuant to clauses
     (i) through (v) above, which, together with any other outstanding Debt
     Incurred pursuant to this clause (vi), has an aggregate principal amount
     not in excess of $10 million at any time outstanding. (sec. 1008)
 
     LIMITATION ON DEBT AND PREFERRED STOCK OF SUBSIDIARIES
 
     The Company may not permit any Subsidiary of the Company that is not a
Guarantor to Incur or suffer to exist any Debt or issue any Preferred Stock
except:
 
          (i) Debt or Preferred Stock outstanding on the date of the Indenture
     after giving effect to the application of the proceeds of the Notes;

of such Person to such Person or a Wholly-Owned Subsidiary of such Person or by
such Person to a Wholly-Owned Subsidiary of such Person) of (i) shares of

rent required to be paid by such Person under such lease during the initial term
thereof as determined in accordance with generally accepted accounting
principles, discounted from the last date of such initial term to the date of
determination at a rate per annum equal to the discount rate which would be
applicable to a Capital Lease Obligation with like term in accordance with

EVENTS OF DEFAULT
 
     The following will be Events of Default under the Indenture: (a) failure to
pay principal of (or premium, if any, on) any Note when due; (b) failure to pay
any interest on any Note when due, continued for 30 days; (c) default in the
payment of principal and interest on Notes required to be purchased pursuant to
an Offer to Purchase as described under "Change of Control" when due and
payable; (d) failure to perform or comply with the provisions described under
"Merger, Consolidation and Sales of Assets" and "Limitation on Certain Asset
Dispositions"; (e) failure to perform any other covenant or agreement of the
Company under the Indenture or the Notes continued for 60 days after written
notice to the Company by the Trustee or holders of at least 25% in aggregate
principal amount of outstanding Notes; (f) default under the terms of any
instrument evidencing or securing Debt of the Company or any Subsidiary having
an outstanding principal amount of $5.0 million individually or in the aggregate
which default results in the acceleration of the payment of such indebtedness or
constitutes the failure to pay such indebtedness when due; (g) the rendering of
a final judgment or judgments (not subject to appeal) against the Company or any
Subsidiary an amount in excess of $5.0 million which remains undischarged or
unstayed for a period of 45 days after the date on which the right to appeal has
expired; and (h) certain events of bankruptcy, insolvency or reorganization
affecting the Company or any Subsidiary. (sec. 501) Subject to the provisions of
the Indenture relating to the duties of the Trustee in case an Event of Default
(as defined) shall occur and be continuing, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request or direction of any of the holders of Notes, unless such holders shall
have offered to the Trustee reasonable indemnity. (sec. 603) Subject to such
provisions for the indemnification of the Trustee, the holders of a majority in
aggregate principal amount of the outstanding Notes will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee. (sec. 512)
 
     If an Event of Default (other than an Event of Default described in Clause
(h) above) shall occur and be continuing, either the Trustee or the holders of
at least 25% in aggregate principal amount of the outstanding Notes may
accelerate the maturity of all Notes; provided, however, that after such
acceleration, but before a judgment or decree based on acceleration, the holders
of a majority in aggregate principal amount of outstanding Notes may, under
certain circumstances, rescind and annul such acceleration if all Events of
Default, other than the non-payment of accelerated principal, have been cured or
waived as provided in the Indenture. If an Event of Default specified in Clause
(h) above occurs, the outstanding Notes will ipso facto become immediately due
and payable without any declaration or other act on the part of the Trustee or
any holder. (sec. 502) For information as to waiver of defaults, see
"Modification and Waiver."
 
     Notwithstanding the foregoing, upon an acceleration of the Notes or an
Event of Default specified in Clause (h) above, in each case prior to November
1, 2001, the holders of Notes will be entitled to receive only a default amount
equal to the Accreted Value of the Notes, which until November 1, 2001 will be
less than the face amount of such Notes.
 
     No holder of any Note will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless such holder shall
have previously given to the Trustee written notice of a continuing Event of
Default (as defined) and unless also the holders of at least 25% in aggregate
principal amount of the outstanding Notes shall have made written request, and
offered reasonable indemnity, to the Trustee to institute such proceeding as
trustee, and the Trustee shall not have received from the holders of a majority
in aggregate principal amount of the outstanding Notes a direction inconsistent
with such request and shall have failed to institute such proceeding within 60
days. (sec. 507) However, such limitations do not apply to a suit instituted by
a holder of a Note for enforcement of payment of the principal of and premium,
if any, or interest on such Note on or after the respective due dates expressed
in such Note. (sec. 508)
 
                                       105
<PAGE>   108
 
     The Company will be required to furnish to the Trustee quarterly a
statement as to the performance by the Company of certain of its obligations
under the Indenture and as to any default in such performance. (sec. 1018)
 
SATISFACTION AND DISCHARGE OF THE INDENTURE
 
     The Indenture will cease to be of further effect as to all outstanding
Notes (except as to (i) rights of registration of transfer and exchange and the
Company's right of optional redemption, (ii) substitution of apparently
mutilated, defaced, destroyed, lost or stolen Notes, (iii) rights of holders of
Notes to receive payment of principal of and premium, if any, and interest on
the Notes, (iv) rights, obligations and immunities of the Trustee under the
Indenture and (v) rights of the holders of the Notes as beneficiaries of the
Indenture with respect to any property deposited with the Trustee payable to all
or any of them), if (x) the Company will have paid or caused to be paid the
principal of and premium, if any, and interest on the Notes as and when the same
will have become due and payable or (y) all outstanding Notes (except lost,
stolen or destroyed Notes which have been replaced or paid) have been delivered
to the Trustee for cancellation.
 
DEFEASANCE
 
     The Indenture will provide that, at the option of the Company, (a) if
applicable, the Company will be discharged from any and all obligations in
respect of the outstanding Notes or (b) if applicable, the Company may omit to
comply with certain restrictive covenants, that such omission shall not be
deemed to be an Event of Default under the Indenture and the Notes, in either
case (A) or (B) upon irrevocable deposit with the Trustee, in trust, of money
and/or U.S. government obligations which will provide money in an amount
sufficient in the opinion of a nationally recognized firm of independent
certified public accountants to pay the principal of and premium, if any, and
each installment of interest, if any, on the outstanding Notes. With respect to
clause (B), the obligations under the Indenture other than with respect to such
covenants and the Events of Default other than the Events of Default relating to
such covenants above shall remain in full force and effect. Such trust may only
be established if, among other things (i) with respect to clause (A), the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling or there has been a change in law, which in the Opinion of
Counsel provides that holders of the Notes will not recognize gain or loss for
Federal income tax purposes as a result of such deposit, defeasance and
discharge and will be subject to Federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such deposit,
defeasance and discharge had not occurred; or, with respect to clause (B), the
Company has delivered to the Trustee an Opinion of Counsel to the effect that
the holders of the Notes will not recognize gain or loss for Federal income tax
purposes as a result of such deposit and defeasance and will be subject to
Federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such deposit and defeasance had not occurred;
(ii) no Event of Default or event that with the passing of time or the giving of
notice, or both, shall constitute an Event of Default shall have occurred or be
continuing; (iii) the Company has delivered to the Trustee an Opinion of Counsel
to the effect that such deposit shall not cause the Trustee or the trust so
created to be subject to the Investment Company Act of 1940; and (iv) certain
other customary conditions precedent are satisfied. (sec. 1301)
 
MODIFICATION AND WAIVER
 
     Modifications and amendments of the Indenture may be made by the Company
and the Trustee with the consent of the holders of a majority in aggregate
principal amount of the outstanding Notes; provided, however, that no such
modification or amendment may, without the consent of the holder of each
outstanding Note affected thereby, (a) change the due date of any installment of
principal or interest on any Note, (b) reduce the principal amount of, (or the
premium) or interest on, any Note, (c) change the currency of payment of
principal of, (or premium) or interest on, any Note,
 
                                       106
<PAGE>   109
 
(d) impair the right to institute suit for the enforcement of any payment on or
with respect to any Note, (e) reduce the above-stated percentage of outstanding
Notes necessary to modify or amend the Indenture, (f) reduce the percentage of
aggregate principal amount of outstanding Notes necessary for waiver of
compliance with certain provisions of the Indenture or for waiver of certain
defaults, (g) modify any provisions of the Indenture relating to the
modification and amendment of the Indenture or the waiver of past defaults or
covenants, except as otherwise specified, or (h) following the mailing of any
Offer to Purchase, modify any Offer to Purchase for the Notes required under the
"Limitation on Asset Dispositions" and the "Change of Control" covenants
contained in the Indenture in a manner materially adverse to the holders
thereof. (sec. 902)
 
     The holders of a majority in aggregate principal amount of the outstanding
Notes, on behalf of all holders of Notes, may waive compliance by the Company
with certain restrictive provisions of the Indenture. (sec. 1020) Subject to
certain rights of the Trustee, as provided in the Indenture, the holders of a
majority in aggregate principal amount of the outstanding Notes, on behalf of
all holders of Notes, may waive any past default under the Indenture, except a
default in the payment of principal, premium or interest or a default arising
from failure to purchase any Note tendered pursuant to an Offer to Purchase.
(sec. 513)
 
     Notwithstanding the foregoing, without the consent of any holder of Notes,
the Company and the Trustee may amend or supplement the Indenture and the Notes:
 
          (a) to cure any ambiguity, defect or inconsistency;
 
          (b) to provide for uncertificated Notes in addition to or in place of
     certificated Notes;
 
          (c) to provide for the assumption of the Company's obligations to
     holders of the Notes in the case of a merger or consolidation or to secure
     the Notes;
 
          (d) to make any change that would provide any additional rights or
     benefits to the holders of the Notes or that does not adversely affect the
     legal rights under the Indenture of any such holder; or
 
          (e) to comply with requirements of the Commission in order to effect
     or maintain the qualification of the Indenture under the Trust Indenture
     Act. (sec. 901)
 
GOVERNING LAW
 
     The Indenture and the Notes will be governed by the laws of the State of
New York.
 
THE TRUSTEE
 
     The Indenture provides that, except during the continuance of an Event of
Default, the Trustee will perform only such duties as are specifically set forth
in the Indenture. During the existence of an Event of Default, the Trustee will
exercise such rights and powers vested in it under the Indenture and use the
same degree of care and skill in its exercise as a prudent person would exercise
under the circumstances in the conduct of such person's own affairs. (sec.sec.
601)
 
     The Indenture and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the Trustee, should it
become a creditor of the Company, to obtain payment of claims in certain cases
or to realize on certain property received by it in respect of any such claim as
security or otherwise. The Trustee is permitted to engage in other transactions
with the Company or any Affiliate, provided, however, that if it acquires any
conflicting interest (as defined in the Indenture or in the Trust Indenture
Act), it must eliminate such conflict or resign. (sec.sec. 608, 613)

                     DESCRIPTION OF OTHER CREDIT FACILITIES
 
AT&T CREDIT FACILITY
 
     The AT&T Credit Facility currently provides the Company a secured line of
credit totalling $50.0 million which has been used to provide financing for the
acquisition and construction of telecommunications networks and the purchase of
equipment related to the construction and operation of the Company's networks in
cities approved by AT&T Credit on a project basis. The terms of the AT&T Credit
Facility provide for two years of capitalized interest, one year of interest
only payments and a six-year principal and interest payout period thereafter.
Indebtedness under the AT&T Credit Facility is secured by the assets of certain
subsidiaries of the Company and is guaranteed by intermediate subsidiaries of
the Company. The facility is further secured by the stock of such subsidiaries
and such guarantors. The AT&T Credit Facility contains covenants substantially
the same as the covenants in the Notes and also contains covenants applicable to
such subsidiaries and such guarantors which place certain additional limitations
on the ability of such entities to incur indebtedness, create liens, engage in
new businesses, dispose of assets, issue additional capital stock and effect
mergers and consolidations.
 
BANK CREDIT FACILITY
 
     The Bank Credit Facility provides the subsidiary operating the Company's
Tulsa, Oklahoma network the ability to borrow amounts up to $10 million from
time to time prior to June 30, 1997, with a final maturity of all loans no later
than June 30, 2002, with interest only payment through August 31, 1997 and a 4.5
year principal payout period thereafter. The Bank Credit Facility is secured by
the assets and stock of the subsidiary. The loan agreement contains certain
restrictive covenants, including limitations on the ability of the subsidiary to
declare and pay dividends to the Company, to incur additional indebtedness, to
make loans and advances and to engage in transactions with the Company (except
for reimbursement for services rendered on arms-length terms and repayment of up
to $10 million of subordinated debt prior to June 30, 1997 in the absence of a
default under the Bank Credit Facility). The Bank Credit Facility contains
financial covenants, including limitations on the ratios of the subsidiary's
annualized operating cash flow to its outstanding debt, interest expense and
debt service costs and requirements for the maintenance of a minimum amount of
annualized operating cash flow. At September 30, 1996, there was $100,000 of
outstanding indebtedness under the Bank Credit Facility.
 
10 7/8% SENIOR DISCOUNT NOTES
 
     On February 26, 1996, the Company completed the issuance and sale of $425.0
million aggregate principal amount of the 10 7/8% Senior Discount Notes for
which the Company received proceeds net of underwriting discounts of
approximately $241.0 million. The 10 7/8% Senior Discount Notes rank pari passu
with the Notes and contain covenants substantially the same as the covenants in
the Notes.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
     The following is a summary of certain federal income tax consequences
associated with the exchange of the Private Notes for Exchange Notes and with
the ownership of the Notes. Except where noted, it deals only with Notes held as
capital assets by a United States holder (generally, a citizen or resident of
the United States, a corporation, a partnership or other entity created or
organized in or under the laws of the United States or any political subdivision
thereof, or an estate or trust the income of which is subject to United States
federal income taxation regardless of its source) and does not deal with special
situations, such as those of dealers in securities, financial institutions, life
insurance companies, or United States holders whose "functional currency" is not
the U.S. dollar. Furthermore, the discussion below is based upon the provisions
of the Internal Revenue Code of 1986, as amended (the "Code"), and regulations,
rulings and judicial decisions thereunder as of the date hereof, and, at any
time and without prior notice, such authorities may be repealed, revoked or
modified so as to result in federal income tax consequences different from those
discussed below.
 
     PERSONS CONSIDERING THE EXCHANGE OF THE PRIVATE NOTES FOR EXCHANGE NOTES
SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE FEDERAL INCOME TAX
CONSEQUENCES AND THE TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY OTHER TAXING
JURISDICTION OF SUCH AN EXCHANGE.
 
THE EXCHANGE
 
     The exchange of Private Notes for Exchange Notes should not be treated as a
taxable transaction for federal income tax purposes because the Exchange Notes
will not be considered to differ materially in kind or extent from the Private
Notes. Rather, the Exchange Notes received by a holder of Private Notes should
be treated as a continuation of the Private Notes in the hands of such holder.
As a result, there should be no material federal income tax consequences to
holders exchanging Private Notes for Exchange Notes.
 
ORIGINAL ISSUE DISCOUNT
 
     The issuance of the Private Notes resulted in original issue discount
("OID") in an amount equal to the excess of the stated redemption price at
maturity over the issue price of the Private Notes. The exchange of Private
Notes for Exchange Notes will not alter the application of the OID rules to
holders of the Private Notes.
 
     The "issue price" of a Note is equal to the first price at which a
substantial number of Notes were sold for money, excluding sales to
underwriters, placement agents or wholesalers. The "stated redemption price at
maturity" is the sum of all payments to be made on the Notes other than
"qualified stated interest". The term "qualified stated interest" means,
generally, stated interest that is unconditionally payable in cash or in
property (other than debt instruments of the issuer) at least annually at a
single fixed rate or, subject to certain conditions, based on one or more
interest indices. Interest is payable at a single fixed rate only if the rate
appropriately takes into account the length of the interval between payments.
 
     Holders of Notes who purchased such Notes in the Private Note Offering
must, in general, include in income OID calculated on a constant-yield method in
advance of the receipt of some or all of the related cash payments. The amount
of OID includible in income by an initial holder of Notes is the sum of the
"daily portions" of OID with respect to such Notes for each day during the
taxable year or portion of the taxable year in which such holder held such Notes
("Accrued OID"). The daily portion is determined by allocating to each day in
any "accrual period" a pro rata portion of the OID allocable to that accrual
period. The "accrual period" for the Notes may be of any length selected by the
holder and may vary in length over the term of the Notes, provided that each
accrual period is no longer than one year and each scheduled payment of
principal or interest occurs on the first day or the final day of an accrual
period. The amount of OID allocable to any accrual period is an amount equal to
the excess, if any, of (a) the product of the Note's adjusted issue price at the
beginning of
 
                                       109
<PAGE>   112
 
such accrual period and the yield to maturity of the Note (determined on the
basis of compounding at the close of each accrual period and properly adjusted
for the length of the accrual period) over (b) the sum of any qualified stated
interest allocable to the accrual period. OID allocable to the final accrual
period is the difference between the amount payable at maturity of the Note
(other than a payment of qualified stated interest) and the Note's adjusted
issue price at the beginning of the final accrual period. Special rules will
apply for calculating OID for an initial short accrual period. The "adjusted
issue price" of a Note at the beginning of any accrual period is equal to its
original issue price ($562.77 per $1,000 principal amount of Notes) increased by
the Accrued OID for each prior accrual period (determined without regard to the
amortization of any acquisition or bond premium, as described below) and reduced
by any payments made on such Notes (other than qualified stated interest) on or
before the first day of the accrual period. Under these rules, a holder will
have to include in income increasingly greater amounts of OID in successive
accrual periods. The Company is required to provide information returns stating
the amount of OID accrued on Notes held of record by persons other than
corporations and other exempt holders.
 
     Holders of any Notes may elect to treat all interest on the Notes as OID
and calculate the amount includible in gross income under the constant yield
method described above. For purposes of this election, interest includes stated
interest, acquisition discount, OID, de minimis OID, market discount, de minimis
market discount and unstated interest, as adjusted by any amortizable bond
premium or acquisition premium. The election is to be made for the taxable year
in which the holder acquired a Note, and may not be revoked without the consent
of the Internal Revenue Service (the "IRS"). Holders should consult with their
own tax advisors regarding this election. The exchange of Private Notes for
Exchange Notes will not extend or otherwise alter the period in which this
election may be made.
 
     If a bankruptcy case is commenced by or against the Company under the U.S.
Bankruptcy Code after the issuance of the Notes, the claim of a holder of a Note
with respect to the principal amount thereof may be limited to an amount equal
to the sum of (i) the initial offering price and (ii) that portion of the
original issue discount that is not deemed to constitute "unmatured interest"
for purposes of the U.S. Bankruptcy Code. Any OID that was not amortized as of
any such bankruptcy filing would constitute "unmatured interest."
 
MARKET DISCOUNT
 
     If a holder has purchased, or subsequently purchases, a Note for an amount
that is less than the "revised issue price" for such Note, the amount of the
difference will be treated as "market discount" for federal income tax purposes,
unless such difference is less than a specified de minimis amount. The Code
provides that, for these purposes, the "revised issue price" of a Note equals
the Note's original issue price ($562.77 per $1,000 principal amount of Notes)
increased by the amount of OID that has accrued on the Note. Under the market
discount rules, a holder will be required to treat any gain on the maturity,
sale, exchange, retirement or other disposition of, a Note as ordinary income to
the extent of the market discount which has not previously been included in
income and is treated as having accrued on such Note at the time of such payment
or disposition. In addition, a holder may be required to defer, until the
maturity of the Note or its earlier disposition in a taxable transaction, the
deduction of all or a portion of the interest expense on any indebtedness
incurred or continued to purchase or carry such Note.
 
     Any market discount will be considered to accrue ratably during the period
from the date of acquisition to the maturity date of the Note, unless the holder
elects to accrue on a constant yield method. A holder of a Note may elect to
include market discount in income currently as it accrues (on either a ratable
or constant yield method), in which case the rule described above regarding
deferral of interest deductions will not apply. This election to include market
discount in income currently, once made, applies to all market discount
obligations acquired on or after the first taxable year to which the election
applies and may not be revoked without the consent of the IRS. Holders should
consult with their own tax advisors regarding this election. The exchange of
Private Notes for
 
                                       110
<PAGE>   113
 
Exchange Notes should not be treated as a purchase of the Exchange Notes for
federal income tax purposes and will not cause any holder of the Notes not
currently subject to the market discount rules to become subject to them. Any
purchaser of the Private Notes that is subject to the market discount rules will
continue to be subject to the market discount rules to the same extent as prior
to the exchange.
 
PREMIUM
 
     A holder that has purchased, or subsequently purchases, a Note for an
amount that is greater than the adjusted issue price of the Note but equal to or
less than the sum of all amounts payable on the Note after the purchase date
other than payments of qualified stated interest will be considered to have
purchased such Note at an "acquisition premium." Under the acquisition premium
rules, the amount of OID which such holder must include in its gross income with
respect to such Note for any taxable year will be reduced by the portion of such
acquisition premium properly allocable to such year.
 
     A holder that has purchased, or subsequently purchases, a Note for an
amount greater than the sum of all amounts payable on the Note after the
purchase date, other than payments of qualified stated interest, will be
considered to have purchased such Note with a "bond premium." The holder may
elect, subject to certain limitations, to deduct the allowable amortizable bond
premium when computing such holder's taxable income. Holders should consult with
their tax advisors regarding this election. The exchange of the Private Notes
for the Exchange Notes will not be treated as a purchase of the Notes creating
amortizable bond premium.
 
SALE, EXCHANGE AND RETIREMENT OF NOTES
 
     A holder's adjusted tax basis in a Note will, in general, be the holder's
cost therefor, increased by OID or market discount included in the holder's
income and reduced by any amortized premium and any cash payments on the Notes
other than qualified stated interest. Upon the sale, exchange or retirement of a
Note, a holder will recognize gain or loss equal to the difference between the
amount realized upon the sale, exchange or retirement (less any accrued
qualified stated interest, which will be taxable as such) and the adjusted tax
basis of the Note. Except with respect to market discount (see above), such gain
or loss will be capital gain or loss and will be long-term capital gain or loss
if at the time of sale, exchange or retirement the Note has been held for more
than one year. Under current law, net capital gains of individuals are, under
certain circumstances, taxed at lower rates than items of ordinary income. The
deductibility of capital losses is subject to limitations.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
     In general, information reporting requirements will apply to certain
payments of principal, interest, and premium paid on Notes and to the proceeds
of sale of a Note made to United States holders other than certain exempt
recipients (such as corporations). A 31% backup withholding tax will apply to
such payments if the United States holder fails to provide a taxpayer
identification number or certification of foreign or other exempt status or
fails to report in full dividend and interest income.
 
                              PLAN OF DISTRIBUTION
 
     This Prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of any Exchange Notes
received in exchange for Private Notes acquired by such broker-dealer as a
result of market-making or other trading activities. Each broker-dealer that
receives Exchange Notes for its own account in exchange for such Private Notes
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. The Company has
agreed that for a period of up to 90 days after the Expiration Date, it will
make this Prospectus, as amended or supplemented, available to
 
                                       111
<PAGE>   114
 
any such broker-dealer that requests copies of this Prospectus in the Letter of
Transmittal for use in connection with any such resale.
 
     The Company will not receive any proceeds from any sale of Exchange Notes
by broker-dealers or any other persons. Exchange Notes received by
broker-dealers for their own account pursuant to the Exchange Offer may be sold
from time to time in one or more transactions in the over-the-counter market, in
negotiated transactions or through the writing of options on the Exchange Notes,
or a combination of such methods of resale, at market prices prevailing at the
time of resale or negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such broker-dealer and/or the
purchasers of any such Exchange Notes. Any broker-dealer that resells Exchange
Notes that were received by it for its own account pursuant to the Exchange
Offer in exchange for Private Notes acquired by such broker-dealer as a result
of market-making or other trading activities and any broker-dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of Exchange Notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. The Letter of Transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.
 
     The Company has agreed to pay all expenses incident to the Company's
performance of, or compliance with, the Registration Rights Agreement and will
indemnify the holders of Private Notes (including any broker-dealers), and
certain parties related to such holders, against certain liabilities, including
liabilities under the Securities Act.
 
                         VALIDITY OF THE EXCHANGE NOTES
 
     The validity of the Exchange Notes will be passed upon for the Company by

     The unaudited pro forma combined consolidated financial information is
intended for informational purposes only and is not necessarily indicative of
the future financial position or future results of operations of the combined

been in effect as of the date or for the periods presented.

accompanying notes should be read in conjunction with and are qualified in their

   NOTES TO PRO FORMA COMBINED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
 
STATEMENT OF OPERATIONS
 
     The following notes to the pro forma combined consolidated financial
statements represent the explanations related to the pro form adjustments to the
historical statements of operations of BFP, BTC and City Signal, Inc. (CSI), as
applicable.
 
 1. Represents elimination of revenues and expenses of BTC's subsidiary, Brooks
    Telecommunications International, Inc. (BTI) due to the distribution by BTC
    to its shareholders, prior to the merger with the Company, of its BTI
    subsidiary (the BTI Spin-off).
 
 2. Represents the elimination of management and consulting fee revenue charged
    by BTC to the Company associated with the development of networks and the
    elimination of expenses recorded by the Company for payments made to BTC.
    Certain costs were capitalized to the Company's networks at the time they
    were incurred.
 
 3. Amount represents the increase in annual amortization of the pro forma
    excess of the costs over the fair value of the net assets acquired
    (goodwill) in association with the BTC merger of approximately $6,550,000.
    The amortization reflects the establishment of additional goodwill of
    $4,470,000 in excess of the goodwill existing on the financial statements of
    BTC of $2,080,000 at December 31, 1995. The additional amount of $4,470,000
    is amortized over a period of 25 years.
 
 4. Represents the elimination of the management fee received by CSI from a
    related entity which is not part of the City Signal Acquisition.
 
 5. Amount represent the depreciation, over an average period of approximately
    12.5 years, of assets which aggregate $7,792,000 and were acquired by the
    Company from a related entity of CSI. Such assets represent buildings and
    equipment and are included in fixed assets within the pro forma combined
    consolidated balance sheet.
 
 6. Amount represents the annual amortization, over a period of 25 years, of the
    pro forma goodwill related to the CSI acquisition of approximately
    $15,773,000.
 
 7. The adjustment represents the elimination of the gain on the sale of CSI's
    Las Vegas, Nevada and Memphis, Tennessee systems. This gain is reflected in
    the statement of operations of CSI and is non-recurring in nature.
 
 8. The adjustment represents the elimination of interest expense on outstanding
    long-term debt of CSI. This interest is reflected in the statement of
    operations of CSI and is eliminated as it is non-recurring in nature due to
    the pro forma adjustment for the repayment of $8,804,000 of outstanding
    debt, and the adjustment of $3,783,000 of debt payable to a related party
    which was not assumed in the City Signal Acquisition.
 
 9. The adjustment represents the net effects of salaries and benefits expense
    for individuals who will become employees of the Company, additional
    property taxes which will be assumed by CSI in conjunction with the
    acquisition of certain properties from a related company of CSI, and the
    elimination of building rent paid by a related company to CSI.
 
10. Pro forma loss per share has been computed using the absolute number of
    shares of Common Stock and Common Stock equivalents outstanding after giving
    effect to the shares issued in connection with the BTC merger and the City
    Signal Acquisition. The number of shares used in computing pro forma loss
    per share was 20,951,862. Pursuant to Securities and Exchange Commission
    Staff Accounting Bulletin No. 83, shares issued during 1995 at prices below
    the initial public offering price per share and stock options and warrants
    granted with exercise prices below the initial public offering price of
    $27.00 during the twelve-month period preceding

   NOTES TO PRO FORMA COMBINED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                                  (CONTINUED)
 
    the date of the initial filing of the Registration Statement relating to the
    Company's May 1996 IPO have been included in the calculation of common stock
    equivalent shares, using the treasury stock method, as if such shares,
    options and warrants were outstanding for all of 1995.
 
11. Represents the CSI revenues, expenses and interest expense for January 1996.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION
 
     The consolidated balance sheet of Brooks Fiber Properties, Inc. ("BFP" or
the "Company") at December 31, 1995 was obtained from the Company's audited
balance sheet as of that date. All other financial statements contained herein
are unaudited and, in the opinion of management, contain all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation. Operating results for the three months and nine months ended
September 30, 1996 are not necessarily indicative of the results that may be
expected for the year ending December 31, 1996. The Company's accounting
policies and certain other disclosures are set forth in the notes to the
Company's audited consolidated financial statements as of and for the year ended
December 31, 1995.
 
2. CASH AND CASH EQUIVALENTS
 
     For the purpose of reporting cash flows, cash and cash equivalents consist
primarily of cash on hand and highly liquid securities with insignificant
interest-rate risk and original maturities of three months or less at date of
acquisition.
 
3. MARKETABLE SECURITIES
 
     Marketable securities consist of treasury bills, commercial paper, and
repurchase agreements with original maturities beyond three months but less than
twelve months. Marketable securities are stated at cost, adjusted for discount
accretion and premium amortization. The securities in the Company's portfolio
are classified as "held to maturity", as management has the intent and ability
to hold those securities to maturity.
 
4. ACQUISITIONS
 
     Pursuant to an Agreement and Plan of Merger between Brooks
Telecommunications Corporation (BTC) and the Company, BTC was merged into the
Company on January 2, 1996, and the securities of the Company held by BTC were
canceled. Following the merger, the former holders of BTC's common stock,
preferred stock, convertible notes, options and warrants received shares of the
Company's common stock, options, and warrants. After the consideration of the
shares of BFP held by BTC at the time of acquisition, the Company issued 756,340
shares of common stock valued at $12.50 per share and certain options and
warrants (see Note 8). Intangible assets of approximately $6.1 million were
recorded as a result of this acquisition.
 
     On January 31, 1996, the Company acquired City Signal, Inc., a provider of
competitive access and local exchange services in Michigan and Ohio, and certain
assets of a related entity, from an unrelated party. In connection with the
acquisition, the Company issued approximately 2.2 million shares of common stock
and assumed certain specified liabilities. Intangible assets of approximately
$13.1 million were recorded as a result of this acquisition. In addition, the
Company granted the seller the option to require the Company to repurchase any
or all shares at a price of $12.50 per share on or before February 1, 1998. In
conjunction with the Company's initial public offering (see Note 7), the holder
of such shares sold 10% of the shares. Accordingly, approximately 2.0 million
shares remain subject to redemption.
 
     Effective July 1, 1996, the Company acquired 100% of the stock of ALD
Communications, Inc. ("ALD"), a switchless reseller of long distance services,
and Tenant Network Services, Inc. ("TNS"), a wholly-owned subsidiary of ALD
which acts as a shared tenant service provider of telecommunications services,
both of which provide their services primarily to customers in the San
Francisco, California area.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     Effective September 1, 1996, the Company acquired 100% of the stock of
Bittel Telecommunications Corporation ("Bittel"), a switch-based reseller of
long distance services, with such services provided primarily to customers in
the San Francisco and Los Angeles, California area.
 
     The above acquisitions were accounted for using the purchase method of
accounting and, accordingly, the results of operations of the acquired companies
have been included in the Company's consolidated financial statements since the
effective dates of acquisition. The aggregate purchase price for these
acquisitions was allocated based on fair values as follows:

     In June 1996, the Company and MCImetro Access Transmission Services, Inc.
("MCImetro") entered into an agreement pursuant to which MCImetro has acquired a
15% interest in the Company's Sacramento, California network for $4.5 million,
and has invested an additional $3.5 million in the Company's San Jose joint
venture company. In accordance with the provisions of the agreements between the
Company and MCImetro, on October 10, 1996, MCImetro exchanged the agreed value
of these investments for approximately 3.2% of the Company's common stock.
 
     In June 1996, the Company formed a strategic alliance with World-Net
Access, Inc., ("World-Net") through a $5 million investment in exchange for a 20
percent fully-diluted interest in World-Net. The investment in World-Net is
classified as Investment in Minority-Owned Venture on the Company's consolidated
balance sheet. World-Net is a privately-held, development stage company founded
to form a national Internet Service Provider network. (See Note 11 for
discussion of an additional commitment to World-Net.)

7. SHAREHOLDERS' EQUITY
 
     Effective January 2, 1996, the Company's Board of Directors authorized a
20-for-1 split for each share of common stock and adjusted all outstanding
common stock options and warrants accordingly. All share data presented within
the consolidated financial statements have been revised to reflect the 20-for-1
stock split.
 
     On May 2, 1996, the Company completed its initial public offering of
7,385,331 shares of Common Stock at a price of $27.00 per share, for gross
proceeds of approximately $199.4 million and proceeds net of underwriting
discounts, advisory fees and expenses of approximately $185.2 million.
 
8. STOCK OPTIONS AND WARRANTS
 
     The Company's 1993 Stock Option Plan (the Plan) authorizes the granting of
options and stock appreciation rights covering up to 3,400,000 shares of common
stock. The options generally vest over a period of three years from the date of
grant.
 
     Stock option activity for the Plan for the nine months ended September 30,

9. LONG-TERM DEBT
 
     On February 26, 1996, the Company completed the issuance and sale of $425.0
million aggregate principal amount of 10 7/8% Senior Discount Notes due March 1,
2006, for which gross proceeds of approximately $250.0 million were received. No
cash payments of interest are required prior to September 1, 2001. Commencing at
such time, the Company will be required to make semi-annual interest payments on
the 10 7/8% Senior Discount Notes, totaling approximately $46.2 million
annually.
 
10. PRO FORMA LOSS PER SHARE
 
     Pro forma loss per share has been computed using the number of shares of
common stock and common stock equivalents outstanding. The weighted average
number of shares used in computing pro forma loss per share was 28,368,352 and
24,071,672 for the three and nine month periods ended September 30, 1996,
respectively, and 19,523,584 for the three and nine month periods ended
September 30, 1995. Pursuant to Securities and Exchange Commission Staff
Accounting Bulletin No. 83, shares issued and stock options and warrants granted
at prices below the initial public offering price of $27.00 per share during the
twelve-month period preceding the date of the Company's initial filing of the
Registration Statement related to such initial public offering have been
included in the calculation of common stock equivalent shares for the nine
months ended September 30, 1996, using the treasury stock method, as if they
were outstanding for all of 1995 and for the entire six-month period ended June
30, 1996. For the three months ended September 30, 1996, the weighted average
number of shares was based on common stock outstanding and does not include
common stock equivalents as their inclusion would be anti-dilutive.
 
11. COMMITMENTS AND CONTINGENCIES
 
     During September 1995, GST Tucson Lightwave, Inc. (Lightwave) was permitted
to intervene in litigation originally filed by Brooks Fiber Communications of
Tucson, Inc. a wholly-owned subsidiary of BFP (BFC Tucson). Lightwave filed a
counterclaim against BFC Tucson, BFP, and Tucson Electric Power Company (TEP)
charging BFC Tucson, BFP, and TEP with violations of antitrust laws, all of
which stem from an agreement between BFC Tucson and TEP that allowed BFC Tucson
exclusive rights, for one year, to utilize certain of TEP's rights-of-way. The
original causes of the action have been settled, however, the counterclaim by
Lightwave is currently still pending. The Company believes the claim to be
without merit and intends to vigorously defend against this action. The Company
believes that resolution of the matter will not have a material adverse effect
on the financial condition or results of operations of the Company.
 
     Subsequent to September 30, 1996, the Company committed an additional $15
million to World-Net (see Note 4), which would increase the Company's
fully-diluted interest to 25.5% from its present 20%. It is possible that the
Company may commit additional funds to World-Net in furtherance of this
strategic alliance.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1995 AND 1994
 
1. ORGANIZATION AND DESCRIPTION OF BUSINESS
 
     The consolidated financial statements include the accounts of Brooks Fiber
Properties, Inc. (BFP) and its majority-owned subsidiaries (the Company). The
Company, through its subsidiaries, is a leading provider of competitive local
telecommunications services in selected markets in the United States.
 
     The Company was founded on November 10, 1993 by Brooks Telecommunications
Corporation (BTC) and a group of venture capital investors who, along with BTC
and management of the Company, provided initial equity capital of $40.8 million.
As the Company's founding shareholder, BTC received 1,162,800 founder's shares
of the Company's common stock and founder's warrants to purchase an additional
81,600 shares of the Company's preferred stock (convertible into 1,632,000
shares of common stock).
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a) Principles of Consolidation
 
     The consolidated financial statements include the accounts of all
majority-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated in consolidation.
 
  (b) Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with original
maturities of three months or less at the time of purchase to be cash
equivalents.
 
  (c) Concentration of Credit Risk
 
     For purposes of segment reporting, management believes the Company operates
in the telecommunications industry. The Company's primary customers are long
distance carriers and businesses within the Company's markets. The Company has
no significant credit risk concentration. One long distance carrier accounted
for 24% of total revenues for the year ended December 31, 1995.
 
  (d) Networks and Equipment
 
     Networks and equipment are stated at cost. Costs of construction are
capitalized, including direct interest costs related to construction. Leasehold
improvements are amortized using the straight-line method over their useful life
or lease term, whichever is shorter. Depreciation is provided using the
straight-line method over the estimated useful lives of the assets as follows:

  (e) Other Assets
 
     Goodwill is being amortized using the straight-line method over 25 years
from the dates of acquisition. The Company reviews the carrying amount of
goodwill periodically to determine whether any impairment has occurred in the
value of such assets. Based upon the anticipated future income

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
and cash flows from operating activities, in the opinion of management no
impairment has occurred as of December 31, 1995.
 
     Direct incremental costs incurred in the organization and development of
new networks, including the costs associated with negotiating rights-of-way,
obtaining legal/regulatory authorizations, and developing network design, are
deferred and amortized over five years. Preoperating costs represent
substantially all direct incremental nondevelopment costs incurred during the
preoperating phase of a newly constructed network and are amortized over
five-year periods commencing with the start of operations.
 
     Costs of the Company's interest rate cap arrangements purchased under the
terms of debt facilities are deferred and amortized over the contractual period
of the underlying interest rate cap arrangements.
 
     Costs incurred in connection with securing the Company's debt facilities,
including commitment, legal, and other such costs, are deferred and amortized
over the term of the financing.
 
  (f) Revenue Recognition
 
     The Company recognizes revenue on local competitive access services in the
month such services are provided. Revenues and associated costs of facilities
management services are recognized as services are provided.
 
  (g) Income Taxes
 
     The Company accounts for income taxes in accordance with the provisions of
Statement of Financial Accounting Standards (SFAS) No. 109, Accounting for
Income Taxes. SFAS No. 109 utilizes the asset/liability method and deferred
taxes are determined based on the estimated future tax effects of differences
between the financial statement and tax bases of assets and liabilities given
the provisions of the enacted tax laws.
 
  (h) Reclassifications
 
     Certain 1994 amounts have been reclassified to conform with the 1995
presentation.
 
  (i) Fair Value of Financial Instruments
 
     The Company discloses estimated fair values for its financial instruments.
A financial instrument is defined as cash or a contract that both imposes on one
entity a contractual obligation to deliver cash or another financial instrument
to a second entity and conveys to that second entity a contractual right to
receive cash or another financial instrument from the first entity.
 
  (j) Use of Estimates
 
     Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities in the preparation of
financial statements. Actual results could differ from these estimates.
 
  (k) Effect of New Accounting Standards
 
     In March 1995, the Financial Accounting Standards Board (FASB) issued SFAS
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed of," which will require the Company to review for the
impairment of long-lived assets and certain identifiable intangibles to be held
and used by the Company whenever events or changes in

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
circumstances indicate that the carrying amount of an asset may not be
recoverable. Adoption of SFAS No. 121 is required in fiscal year 1996.
 
     In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation," which establishes a fair value based method for financial
accounting and reporting for stock-based employee compensation plans. However,
the new standard allows compensation to continue to be measured by using the
intrinsic value based method of accounting prescribed by Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees," but requires
expanded disclosures. SFAS No. 123 is effective in fiscal year 1996.
 
     While the Company does not know precisely the impact that will result from
adopting SFAS No. 121 and SFAS No. 123, the Company does not expect the adoption
of SFAS No. 121 or SFAS No. 123 to have a material effect on the Company's
consolidated financial position or results of operations.
 
  (l) Pro Forma Loss Per Share
 
     Pro forma loss per share has been computed using the number of shares of
Common Stock and Common Stock equivalents outstanding. The number of shares used
in computing pro forma loss per share was 19,532,584. Pursuant to Securities and
Exchange Commission Staff Accounting Bulletin No. 83, shares issued and stock
options and warrants granted at prices below the initial public offering price
of $27.00 per share during the twelve-month period preceding the date of the
initial filing of the Registration Statement have been included in the
calculation of common stock equivalent shares, using the treasury stock method,
as if they were outstanding for all of 1995.
 
3. ACQUISITIONS AND JOINT VENTURES
 
     On January 31, 1994, the Company acquired certain assets from an unrelated
party that included a telecommunications network in Massachusetts and
rights-of-way for development of networks in Connecticut and Rhode Island.
 
     On October 14, 1994, the Company acquired from an unrelated party 100% of
certain related companies (Phoenix) that included telecommunications networks in
California, a telemanagement services business, and a reseller of long distance
telecommunications services. The Company issued short-term notes of $24.5
million to the seller backed by a letter of credit. As of December 31, 1994, the
notes were repaid using the proceeds from long-term debt.
 
     On March 15, 1995, the Company acquired from an unrelated party 100% of the
assets of a 105-mile competitive access network in Tulsa, Oklahoma.
 
     The above acquisitions were accounted for using the purchase method of
accounting and, accordingly, the results of operations of the acquired companies
have been included in the Company's consolidated financial statements since the
effective dates of acquisition. The aggregate purchase price for the
acquisitions occurring in 1995 and 1994 were allocated based on fair values as
follows:

     In September 1995, the Company and MCI/Metro Access Transmission Services,
Inc. (MCI/Metro), a wholly-owned subsidiary of MCI Communications Corp. (MCI),
entered into agreements for the formation of a joint venture company, which is
majority owned by a subsidiary of the Company, to operate and significantly
expand the Company's existing CAP networks in San Jose, California, and its
environs. The Company transferred the net assets of its network in San Jose to
the joint venture.
 
     During 1995 and 1994, a third-party investor acquired a 6.5% interest in
certain subsidiaries of the Company. In connection with MCI/Metro's investment
in the Company's San Jose network and investments by the third-party investor,
minority investments in the Company's subsidiaries totaling $4.1 million and
$1.1 million were made during the years ended December 31, 1995 and 1994,
respectively.

     Amortization charged to expense for the years ended December 31, 1995 and
1994 and for the period ended December 31, 1993 was $1,356,000, $289,000, and
$3,000, respectively.
 
     The terms of the Company's Loan and Security Agreements (the Agreements)
with AT&T Credit Corporation entered into during 1995 and 1994 require the
purchase of interest rate cap arrangements under which, if the 90-day commercial
paper rate rises above 7.5%, the Company will receive payments to offset the
higher interest rates on long-term debt. These payments, if any, will be
recorded as reductions of interest expense. The contract period and notional
amounts of the interest rate caps as of December 31, 1995 are as follows:

6. LONG-TERM DEBT
 
     During 1995 and 1994, the Company entered into Agreements with AT&T Credit
Corporation to provide financing for the acquisition and construction of
telecommunications networks, the purchase of equipment related to the
construction and operation of the networks, and working capital. As of December
31, 1995, borrowings under the Agreements have a maximum capacity of $49.2
million, with outstanding indebtedness of $43.9 million. The notes bear interest
at the 90-day commercial paper rate plus 4.5% per annum (10.12% at December 31,
1995), payable quarterly beginning two years after the initial borrowing.
Interest not paid during the two-year period will be added to the principal
balance of the notes, not to exceed the maximum borrowing capacity.
 
     The Company is required to pay a commitment fee at the rate of .5% per
annum on the average unused portion of the maximum borrowing capacity of the
Agreements. The fee is payable quarterly and commences six months after the
initial borrowing. Borrowings are secured by the assets and

stock of certain of the Company's subsidiaries. Principal payments begin three
years after the initial borrowing.
 
     In August 1995, the Company entered into a credit agreement with Fleet
National Bank, N.A. (the Bank Credit Agreement) that provides a wholly-owned
subsidiary of the Company the ability to borrow amounts up to $10 million from
time to time prior to June 30, 1997 at an interest rate of 2% over the prime
rate of the bank. Terms of the Bank Credit Agreement further provide for final
maturity of all loans no later than June 30, 2002, interest-only payments
through August 31, 1997, and a 4.5-year principal payout period thereafter. As
of December 31, 1995, borrowings under this facility totaled $100,000 at a rate
of 10.25%.
 
     The aforementioned credit agreements contain certain restrictive and
financial covenants, including limitations on the ability of the subsidiaries to
declare and pay dividends, to incur additional indebtedness, to make loans and
advances, and the maintenance of certain financial ratios and minimum annualized
operating cash flow.
 
     Maturities of long-term debt at December 31, 1995 are as follows:

7. PREFERRED STOCK
 
     The Company's authorized preferred stock consists of 1,040,012 shares, of
which 489,600 shares are designated as Series A-1 Voting Convertible Preferred
Stock (Series A-1), 433,867 shares are designated as Series A-2 Non-Voting
Convertible Preferred Stock (Series A-2), 12,000 shares are designated as Series
B-1 Voting Convertible Preferred Stock (Series B-1), and 4,545 shares are
designated as Series B-2 Non-Voting Convertible Preferred Stock (Series B-2).
The Company has not designated approximately 100,000 shares of preferred stock.
 
     On November 10, 1993, the Company received stock subscriptions for 396,000
shares of Series A-1 and 12,000 shares of Series B-1 preferred stock for an
aggregate committed purchase price of $100 per share. The Company recorded $40.8
million of preferred stock and a subscriptions receivable (as a component of
shareholders' equity) of $40.2 million, net of $600,000 of cash received for the
initial issuance of 6,000 shares of preferred stock. In December 1993,
additional funds of $619,000 were received for the issuance of preferred shares.
During 1995 and 1994, the remaining funds under the subscriptions receivable
were requested and received by the Company. Accordingly, the subscriptions
receivable of $17.8 million as of December 31, 1994 was reclassified as an asset
of the Company, of which $7.75 million was designated to make an acquisition of
long-term assets and was classified as a noncurrent asset.
 
     In August 1995, the Company completed a private placement of 419,705 shares
of Series A-2 and 4,545 shares of Series B-2 preferred stock. Gross proceeds
from the offering totaled $70,001,000.

     Each share of preferred stock may be converted into 20 shares of common
stock at the option of the holder. In addition, Series B preferred stock may be
converted into shares of Series A preferred stock on a share-for-share basis.
The preferred shares automatically convert into common stock upon consummation
of a public offering of the Company's stock of at least $40.0 million and $15.00
per share.
 
     The holders of shares of the Series A and Series B preferred stock are not
entitled to receive cash dividends. No cash dividends may be declared and paid
to the holders of common stock as long as Series A or Series B preferred stock
is outstanding.
 
8. STOCK OPTIONS AND WARRANTS
 
     The Company's 1993 Stock Option Plan (the Plan) authorizes the granting of
options and stock appreciation rights covering up to 3,400,000 shares of common
stock. The options generally vest over a period of three years from the date of
grant.

     During September 1995, GST Tucson Lightwave, Inc. (Lightwave) was permitted
to intervene in litigation originally filed by Brooks Fiber Communications of
Tucson, Inc., a wholly-owned subsidiary of BFP (BFC Tucson). Lightwave filed a
counterclaim against BFC Tucson, BFP, and Tucson Electric Power Company (TEP)
charging BFC Tucson, BFP, and TEP with violations of antitrust laws, all of
which stem from an agreement between BFC Tucson and TEP that allowed BFC Tucson
exclusive rights, for one year, to utilize certain of TEP's rights-of-way. The

the action have been settled; however, the counterclaim by Lightwave is
currently still pending. The Company believes the claim to be without merit and
intends to vigorously defend against this action. The Company believes that
resolution of the matter will not have a material adverse effect on the
financial condition or results of operations of the Company.
 
12. SUBSEQUENT EVENTS
 
     Pursuant to an Agreement and Plan of Merger between BTC and the Company,
BTC was merged into the Company on January 2, 1996, and the securities of the
Company held by BTC were cancelled. Following the merger, the former holders of
BTC's common stock, preferred stock, convertible notes, and options and warrants
received shares of the Company's common stock, options, and warrants. After the
consideration of the shares of BFP held by BTC at the time of the acquisition,
the Company issued an additional 756,340 shares of Common Stock valued at $12.50
per share. Intangible assets of approximately $7 million are expected to be
recorded as a result of this acquisition. The Management Agreement between the
Company and BTC was cancelled.
 
     Also on January 2, 1996, the Company's Board of Directors authorized a
20-for-1 stock split for each share of common stock and adjusted all outstanding
common stock options and warrants accordingly. All share data presented within
the December 31, 1995 consolidated financial statements have been revised to
effect for the stock split.
 
     On January 17, 1996, the Company signed a definitive agreement with an
unrelated party to acquire City Signal, Inc., a provider of competitive access
and local exchange services in Michigan and Ohio, and certain assets of a
related entity. In connection with the acquisition, the Company has agreed to
issue approximately 2.2 million shares of common stock (subject to post-closing
adjustment) and to assume approximately $13.3 million of liabilities. In
addition, the Company has provided the seller with the option to require the
Company to purchase from the seller all or any part of the shares issued in
connection with the acquisition at a price of $12.50 per share on or prior to
the earlier of the first anniversary of the closing or the closing of an initial
public offering of the Company's common stock. The transaction is scheduled to
close into escrow on January 31, 1996. Intangible assets of approximately $15.8
million are expected to be recorded as a result of this acquisition.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES DESCRIPTION OF BUSINESS
 
     City Signal, Inc, (Company) is a provider of local access telecommunication
services. Its activities include construction of fiber optic networks for sale
or lease. Revenue is derived from commercial customers and governmental units
primarily within the state of Michigan for 1995 and the states of Michigan and
Tennessee for 1994.
 
     PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of all
majority-owned entities. All significant intercompany accounts and transactions
have been eliminated in consolidation. The financial statements as of and for
the year ended December 31, 1994, have been restated and reflect the
consolidation of a limited partnership investment which had previously been
accounted for under the equity method. This accounting change did not affect the
reported net assets or net loss for 1994.
 
     INVESTMENT IN LIMITED PARTNERSHIP
 
     The Company's five percent investment in a limited partnership is accounted
for using the cost method.
 
     PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. The cost of property and
equipment is depreciated using the straight-line method over the estimated
useful lives of the assets as follows:
 
<TABLE>
<CAPTION>
                                                                                YEARS
                                                                                -----
        <S>                                                                     <C>

        Fiber optic cable....................................................     15
        Furniture and office equipment.......................................    5-7
        Vehicles.............................................................      5
</TABLE>
 
     Leasehold improvements are amortized using the straight-line method over
their useful life or lease term, whichever is shorter. Uninstalled equipment is
not depreciated until placed into service.
 
     COLLOCATION COSTS
 
     Collocation costs, which primarily represent costs associated with
negotiating rights-of-way, are amortized over five years on a straightline
basis. Accumulated amortization at December 31, 1995 and 1994, was $67,881 and
$71,553, respectively.
 
     REVENUE RECOGNITION
 
     The Company recognizes revenue on its local access services in the month
such services are provided. Revenues associated with the construction of fiber
optic networks are recognized on the percentage of completion method.
 
     INCOME TAXES
 
     The Company, with the consent of its shareholder, has elected to be treated
as an S corporation, resulting in the Company's income being included in the
shareholder's personal income for federal income tax purposes.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     USE OF ESTIMATES
 
     The preparation of consolidated financial statements includes estimates and
assumptions made by management relating to the reporting of assets and
liabilities. Actual results could differ from those estimates.
 
     FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     In 1995, the Company adopted SFAS No. 107, Disclosures About Fair Value of
Financial Instruments, which requires disclosure of fair value information about
certain financial instruments. The carrying amounts of the Company's financial
instruments, which consist of cash, accounts receivable, notes receivable,
accounts payable and long term obligations approximate their fair values.
 
     RECLASSIFICATIONS
 
     Certain 1994 amounts have been reclassified to conform with the 1995
presentation.
 
2. BUILDING AND EQUIPMENT LEASES
 
     The Company leases certain network equipment under lease agreements that
have been classified as capital leases for financial reporting purposes. The
Company also leases office space and equipment under operating leases that
expire at various dates through 2000.
 
     Property and equipment include the following amounts for equipment under
capital leases:

     - The Company has an unsecured $12,000,000 revolving line of credit,
       bearing interest at prime (9.0% and 8.5% at December 31, 1995 and 1994,
       respectively), with an affiliated company controlled by the Company's
       shareholder, of which $2,010,242 and $10,624,744, including interest,
       were outstanding at December 31, 1995 and 1994, respectively. Amounts on

       (see Note 2) and long-term debt (see Note 4).

5. COMMITMENTS AND CONTINGENCIES
 
     The Company adopted both an Employee and an Executive Growth Sharing Plan
on July 1, 1994. Growth sharing units (units) are awarded to eligible
participants based on job classification and the discretion of the employer.
Participants in the Employee Plan vest in the units at a rate of 25% a year
until fully vested at four years. Participants in the Executive Plan are vested
at 33 1/3% a year until fully vested at three years. If a triggering event (as
defined in the plan) occurs, eligible employees will receive a distribution
equivalent to the number of units held times the increase in per unit value from
the date of issuance to the date of the event (as determined by a market
valuation of the Company).

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     A triggering event occurred on January 31, 1996, in connection with the
sale of the Company and a related entity. No liability is yet determinable under
the plan since the combined fair values of the Company and the affiliated
company cannot be computed due to an earn-out provision associated with the sale
of the affiliated company. Any potential liability is not expected to be
material.
 
6. SALE OF ASSETS
 
     - In January 1994, the Company sold customer contracts relating to its
       Detroit, Michigan fiber optic network and the related equipment and fiber
       optic cable comprising the network. A gain on the sale of approximately
       $1,552,000 is reflected in other income.
 
     - In October 1994, the Company sold substantially all of the assets
       comprising its Indianapolis, Indiana fiber optic network. A gain on the
       sale of approximately $1,243,000 is reflected in other income.
 
     - Effective January 31, 1995, the Company sold substantially all of its
       operating assets and related liabilities of its fiber optic networks
       located in Memphis and Nashville, Tennessee for $15,063,925. In addition,
       the Company received a 5% interest in the acquiring limited partnership
       in exchange for the remaining 5% of the net operating assets which had 
       a net book value of $410,000. A gain on the sale of approximately 
       $7,093,000 is reported in other income and represents the excess of the
       sale price over the net book value of assets sold less the $410,000 
       limited partnership interest.
 
       In connection with the sale, the Company provided billing, collecting and
       administrative services to the limited partnership under a management
       services agreement. The liability of $1,140,677 at December 31, 1995
       represents the excess of collections on customer accounts over expenses
       paid to vendors made by the Company on behalf of the limited partnership
       and management fees of $124,306 for the year 1995. The billing and
       collecting services are not reflected in the consolidated statement of
       operations.
 
     - In April 1995, the Company entered into an agreement to sell an
       irrevocable purchase option for its interest in a limited partnership
       (which was previously consolidated in the financial statements) for
       $2,992,114. A gain of approximately $803,000 has been recognized in other
       income, reflecting the amount received in excess of the net assets sold.
 
7. RETIREMENT PLAN
 
     The Company has an investment plan under section 401(k) of the Internal
Revenue Code covering substantially all employees. The Company contributed
$21,833 and $16,209 to the plan during 1995 and 1994, respectively. In
connection with the sale of the Company described in Note 9, the Company has
terminated the plan effective February 1, 1996.

The Board of Directors
Brooks Telecommunications Corporation:
 
     We have audited the accompanying consolidated balance sheet of Brooks
Telecommunications Corporation and subsidiaries as of December 31, 1995, and the
related consolidated statements of operations, changes in shareholders' equity,
and cash flows for the year then ended. These consolidated financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements based on our
audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Brooks
Telecommunications Corporation and subsidiaries as of December 31, 1995, and the
results of their operations and their cash flows for the year then ended in
conformity with generally accepted accounting principles.

             BROOKS TELECOMMUNICATIONS CORPORATION AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
1. ORGANIZATION AND DESCRIPTION OF BUSINESS
 
     The consolidated financial statements include the accounts of Brooks
Telecommunications Corporation (BTC) and its majority-owned subsidiaries (the
Company). All intercompany balances and transactions have been eliminated in
consolidation. The Company provides consulting services to the
telecommunications and cable industries and is engaged in the management and
development of telecommunications networks in the U.S. and China.
 
     The Company's investment in Brooks Fiber Properties, Inc. (BFP) represents
a 14% interest and is carried at cost in the consolidated financial statements.
 
     The Company's investment in SCM Brooks Telecommunications, L.P. (SBP) in
which BTC had a controlling interest, has been consolidated in the financial
statements of the Company.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a) Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents.
 
  (b) Furniture, Fixtures and Equipment
 
     Furniture, fixtures and equipment consist of office furnishings, leasehold
improvements, equipment, and a corporate aircraft which are recorded at cost.
Depreciation of property and equipment is recorded using the straight-line
method over estimated useful lives of the assets ranging from 5 to 15 years.
Leasehold improvements are amortized using the straight-line method over their
estimated useful lives or lease term whichever is shorter.
 
  (c) Other Assets
 
     Goodwill is being amortized using the straight-line method over 25 years
from the dates of acquisition. The Company reviews the carrying amount of
goodwill periodically to determine whether any impairment has occurred in the
value of such assets. Based upon the anticipated future income and cash flows
from operating activities, in the opinion of management no impairment has
occurred as of December 31, 1995.
 
  (d) Income Taxes
 
     The Company accounts for income taxes in accordance with the
asset/liability method whereby deferred taxes are determined based on the
estimated future tax effects of differences between the financial statement and
tax bases of assets and liabilities given the provisions of the enacted tax
laws.
 
  (e) Deferred Revenue
 
     Deferred revenue consists of advance billings for consulting services to be
performed by the Company.
 
  (f) Fair Value of Financial Instruments
 
     The Company discloses estimated fair value for its financial instruments. A
financial instrument is defined as cash or a contract that both imposes on one
entity a contractual obligation to deliver
 
                                      F-45
<PAGE>   161
 
             BROOKS TELECOMMUNICATIONS CORPORATION AND SUBSIDIARIES
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
cash or another financial instrument to a second entity and conveys to that
second entity a contractual right to receive cash or another financial
instrument from the first entity.
 
  (g) Use of Estimates
 
     Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities in the preparation of
financial statements. Actual results could differ from these estimates.
 
  (h) Effect of New Accounting Standards
 
     In March 1995, the Financial Accounting Standards Board (FASB) issued SFAS
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed of," which will require the Company to review for the
impairment of long-lived assets and certain identifiable intangibles to be held
and used by the Company whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. Adoption of SFAS
No. 121 is required in fiscal year 1996.
 
     In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation," which establishes a fair value based method for financial
accounting and reporting for stock-based employee compensation plans. However,
the new standard allows compensation to continue to be measured by using the
intrinsic value based method of accounting prescribed by Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees," but requires
expanded disclosures. SFAS No. 123 is effective in fiscal year 1996.
 
     While the Company does not know precisely the impact that will result from
adopting SFAS No. 121 and SFAS No. 123, the Company does not expect the adoption
of SFAS No. 121 or SFAS No. 123 to have a material effect on the Company's
consolidated financial position or results of operations.
 
3. ACQUISITION
 
     On January 1, 1995, the Company acquired the stock of GDS, a
telecommunications consulting firm. The Company issued 49,977 shares of the
Company's Series D convertible preferred stock at a value of $1,999,094 and
$308,000 in cash in exchange for all of the stock in GDS. The acquisition was
accounted for using the purchase method of accounting and, accordingly, the
results of operations of GDS have been included in the Company's consolidated
financial statements since the date of acquisition. The fair value of net assets
acquired was $213,000 resulting in $2,094,000 of goodwill being recorded at the
date of acquisition.
 
4. INVESTMENTS IN AND LOANS TO VENTURES
 
     Investments in and loans to ventures consist of the following:

     SBP was formed on February 10, 1993 to work with the Chinese government to
coordinate existing telecommunications systems and to design, install, and
operate advanced telecommunications networks in China. The general partner is
SCM Brooks Telecommunications, Inc. (SCM Brooks), which is owned by SCM and the
Company.
 
     On April 17, 1993, SBP entered into a joint venture agreement with Galaxy
New Technology Company (Galaxy) to design, develop, construct, promote, market,
install, and participate in the ownership and profits of a telecommunications
system as a prototype in Guangzhou, China. In connection with this joint
venture, SBP and Galaxy have formed Guangzhou HuaMei Communications Limited (the
HuaMei Interest). The operations of the HuaMei Interest through December 31,
1994 consisted principally of organizational and financing activities, and
construction of the prototype telecommunications network in Guangzhou, China.
SBP's investment in the HuaMei Interest represents a 50% interest and is
accounted for by the equity method.
 
     On December 19, 1994, the Company purchased 30 shares of SCM Brooks, 294
Class A limited partnership shares, and 120 Class B limited partnership shares
in SBP from SCM for $2,850,000, which was recorded as goodwill at the date of
purchase. As a result, the Company has a 53% equity interest in SCM Brooks, 53%
ownership of Class A limited partner shares, and 21% ownership of Class B
limited partner shares of SBP. Also, in conjunction with this transaction, the
Company purchased $150,000 of SCM's promissory notes receivable in SBP.
 
     The profits and losses of the HuaMei Interest will be shared equally by SBP
and Galaxy. As of December 31, 1995, SBP had invested $6,350,000 in the HuaMei
Interest.

8. LINE OF CREDIT
 
     The Company has a $750,000 line of credit from a bank, secured by assets of
the Company. Interest on any borrowings under the line of credit accrues at
prime plus 1% and is payable monthly. The line of credit expires on September 1,
1996. No amounts were advanced under the line of credit during the year ended
December 31, 1995.
 
9. INCOME TAXES
 
     The Company accounts for income taxes in accordance with the provisions of
SFAS No. 109. No provision for income taxes has been made due to the Company's
net operating losses. A valuation allowance is provided when it's more likely
than not some portion of the deferred tax asset will not be realized. The
Company has established a valuation allowance for the entire portion of the net
deferred income tax asset. The valuation allowance increased by $631,000 during
the year ended December 31, 1995.
 
     The actual income tax expense (benefit) differs from the "expected" income
tax expense (benefit), computed by applying the Statutory U.S. Federal corporate
income tax rate of 34% to earnings before income tax expense. The difference
results primarily from the nondeductibility of goodwill and a portion of meals
and entertainment expenses, and the increase in the valuation allowance.
 
     Temporary differences and carryforwards that give rise to deferred tax
assets and liabilities are as follows:

     At the option of the holder, the preferred stock is convertible into shares
of common stock. The preferred shares automatically convert into common stock
upon consummation of a public offering of the Company's common stock, as defined
in the Preferred Stock Purchase Agreement (the Agreement).
 
     If the Company declares or pays any dividend on its common stock, the
holders of the preferred stock are entitled to receive an equivalent dividend
based upon the conversion of the preferred stock into common stock.
 
     The holders of the preferred stock have voting rights equal to the number
of common shares issuable upon conversion and vote as a single class with the
holders of the Company's common stock. The Agreement contains various covenants
and restrictions on the Company, including certain restrictions of the issuance
of additional equity securities by the Company.
 
     The Company, at its option, had certain redemption rights on outstanding
preferred stock. In conjunction with the Agreement and Plan of Merger entered
into on January 2, 1996 (see note 14), the preferred shares were converted to
common stock and the redemption rights were eliminated.
 
13. RELATED-PARTY TRANSACTIONS
 
     During October 1993, the Company entered into a management agreement with
BFP (the Management Agreement). As part of the Management Agreement, the Company
provides certain services to BFP. The Management Agreement has a fee equal to
$250,000 per year adjusted in 1996 and subsequent years for inflation.
Furthermore, certain expenses are reimbursed to the Company as incurred.
Receivables from BFP totaled $152,000 as of December 31,1995. No management fees
were due from BFP as of December 31, 1995.
 
     BTC provides consulting services to the HuaMei Interest in connection with
the joint venture with Galaxy New Technology Company (see note 2). SBP has
agreed to pay for the services rendered by the Company's employees or
consultants. SBP also has agreed to pay for all

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
reasonable out-of-pocket costs incurred by the Company in the performance of the
services. All such services performed and expenses incurred by the Company
during 1995 have been recorded as consulting fee revenues in the accompanying
consolidated statement of operations and totaled $1,080,000 for 1995. Consulting
fee revenues charged to SBP generally are billable to the HuaMei Interest by SBP
in accordance with agreements among the parties.
 
     On January 1, 1995, the Company entered into a one-year consulting
arrangement with BFP. The arrangement is automatically extended for an
additional year if approved by the Board of Directors of BFP. Services under the
arrangement provide for competitive access studies, network design, engineering,
and project management. Consulting fees are based upon an hourly rate fee
schedule. The Company recorded $1,017,000 in revenue related to this arrangement
for 1995.
 
14. SUBSEQUENT EVENT
 
     Pursuant to an Agreement and Plan of Merger between BFP and the Company,
BTC was merged into BFP on January 2, 1996, and the securities of BFP held by
the Company were cancelled. Following the merger, the former holders of the
Company's common stock, preferred stock, convertible notes, and options and
warrants received shares of BFP's common stock, options, and warrants. After the
consideration of the shares of BFP held by the Company at the time of
acquisition, BFP issued an additional 756,340 shares of common stock valued at
$12.50 per share. The Management Agreement between BFP and the Company was
cancelled.
 
     On January 1, 1996, all of the outstanding Common Stock of Brooks
Telecommunications International, Inc. (BTI), a wholly-owned subsidiary of the
Company, was distributed to the shareholders. Prior to the distribution to the
shareholders, the Company transferred its interest in its investment in SBP to
BTI. In addition, a pro rata portion of the Company's cash and cash equivalents
was transferred to BTI prior to the distribution.

                                                                         ANNEX A
 
                                    GLOSSARY
 
     ACCESS CHARGES -- The fees paid by long distance carriers to ILECs or CLECs
for originating and terminating long distance calls on their local networks.
 
     AIN (ADVANCED INTELLIGENT NETWORK) -- A term indicating a network
architecture concept with three basic elements: (i) Signal Control Points
(SCPs)-computers that hold data bases in which customer-specific information is
used by the network to route calls stored; (ii) Signal Switching Points (SSPs)
digital telephone switches which can communicate with SCPs and ask them for
customer-specific instructions as to how the call should be completed; and (iii)
Signal Transfer Points (STPs)-packet switches that shuttle messages between SSPs
and SCPs.
 
     ATM (ASYNCHRONOUS TRANSFER MODE) -- A recently commercialized switching and
transmission technology that is one of a general class of packet technologies
that relay traffic by way of an address contained within the first five bits of
a standard fifty-three bit-long packet or cell. ATM-based packet transport was
specifically developed to allow switching and transmission of mixed voice, data
and video (sometimes referred to as "multi-media" information) at varying rates.
The ATM format can be used by many different information systems, including
LANs.
 
     BROADBAND -- Broadband communications systems can transmit large quantities
of voice, data and video by way of digital or analog signals. Examples of
broadband communication systems include DS-3 fiber optic systems, which can
transmit 672 simultaneous voice conversations, or a broadcast television station
signal that transmits high resolution audio and video signals into the home.
Broadband connectivity is also an essential element for interactive multimedia
applications.
 
     CAP (COMPETITIVE ACCESS PROVIDER) -- A company that provides its customers
with an alternative to the local telephone company for local transport of
private line, special access and interstate transport of switched access
telecommunications services. CAPs are also referred to in the industry as
alternative local telecommunications service providers (ALTs) and metropolitan
area network providers (MANs) and were formerly referred to as alternative
access vendors (AAVs).
 
     CENTRAL OFFICES -- The switching centers or central switching facilities of
the ILECs.
 
     CENTREX -- Centrex is a service that offers features similar to those of a
Private Branch Exchange (PBX), except the equipment is located at the carrier's
premises and not at the premises of the customer. These features include direct
dialing within a given phone system, direct dialing of incoming calls, and
automatic identification of outbound calls. This is a value-added service that
carriers can provide to a wide range of customers who don't have the size or the
funds to support their own on-site PBX.
 
     CLEC (COMPETITIVE LOCAL EXCHANGE CARRIER) -- A CAP that also provides
Switched Local Services, such as local dial tone and centrex.
 
     CO-CARRIER STATUS -- A relationship between a CLEC and an ILEC that affords
each entity the same access to and right on the other's network, and that
provides access and services on an equal basis.
 
     COLLOCATION -- The ability of a CLEC such as the Company to connect its
network to the ILEC's central offices. Physical collocation occurs when a CLEC
places its network connection equipment inside the ILEC's central offices.
Virtual collocation is an alternative to physical collocation pursuant to which
the ILEC permits a CLEC to connect its network to the ILEC's central offices on
comparable terms, even though the CLEC's network connection equipment is not
physically located inside the central offices.
 
                                       A-1
<PAGE>   169
 
     DEDICATED LINES -- Telecommunications lines dedicated or reserved for use
exclusively by particular customers along predetermined routes (in contrast to
telecommunications lines within the ILEC's public switched network).
 
     DESK TOP PRODUCTS -- Desk top products are the various types of
telecommunications equipment located in the offices of end user customers for
individual access to voice, data and video telecommunications services.
 
     DIALING PARITY -- Dialing Parity is among the many issues related to the
telecommunications industry that are being debated for federal legislation.
Essentially, customers should be able to have 1+ and O+ service no matter which
local or long distance carrier they choose. For example, when MCI first got into
the long distance business, customers had to dial a ten digit prefix before the
number they were calling. This was considered unacceptable to many in the
industry who favor "dialing parity."
 
     DIGITAL -- A method of storing, processing and transmitting information
through the use of distinct electronic or optical pulses that represent the
binary code digits 0 and 1. Digital transmission and switching technologies
employ a sequence of these pulses to represent information as opposed to the
continuously variable analog signal. Digital transmission and switching
technologies offer a significant improvement in speed and capacity over analog
techniques, allowing much more efficient and cost-effective transmission of
voice, video, and data.
 
     DIVERSE ROUTING -- A telecommunications network configuration in which
signals are transported simultaneously along two different paths so that if one
cable is cut, traffic can continue in the other direction without interruption
to its destination. The Company's networks generally provide diverse routing.
 
     DOMINANT CARRIER -- A carrier found by the FCC to have market power - i.e.,
the power to control prices for its services.
 
     DS-0, DS-1, DS-3 -- Standard telecommunications industry digital signal
formats, which are distinguishable by bit rate (the number of binary digits (0
and 1) transmitted per second). DS-0 service has a bit rate of 64 kilobits per
second. DS-1 service has a bit rate of 1.544 megabits per second and DS-3
service has a bit rate of 45 megabits per second.
 
     FACILITIES MANAGEMENT -- Management, operation, maintenance, staffing and
support of telecommunications networks or systems.
 
     FCC -- Federal Communications Commission
 
     FDDI (FIBER DISTRIBUTED DATA INTERFACE) -- Based on fiber optics, FDDI is a
100 megabit per second local area network technology used to connect computers,
printers, and workstations at very high speeds. FDDI is also used as backbone
technology to interconnect other LANs.
 
     FIBER MILE -- The number of route miles installed (excluding pending
installations) along a telecommunications path multiplied by the number of
fibers along that path. See the definition of "route miles" below.
 
     FIBER OPTICS -- Fiber optic cable is the medium of choice for the
telecommunications and cable industries. Fiber is immune to electrical
interference and environmental factors that affect copper wiring and satellite
transmission. Fiber optic technology involves sending laser light pulses across
glass strands in order to transmit digital information. A strand of fiber optic
cable is as thick as a human hair yet is said to have more bandwidth capacity
than copper cable the size of a telephone pole.
 
     FIBER OPTIC RING NETWORK -- Most CLECs have built their networks in ring
configurations in order to ensure that, if one segment of a network is damaged
or cut, the traffic is simply re-routed and sent to its destination in the
opposite direction. The Company uses a "self- healing" optical fiber ring
architecture known as SONET.
 
                                       A-2
<PAGE>   170
 
     FRAME RELAY -- Frame Relay is a high speed data packet switching service
used to transmit data between computers. Frame Relay supports data units of
variable lengths at access speeds ranging from 56kbs to 1.5 mbs. This service is
ideal for connecting LANS, but is not appropriate for voice and video
applications due to the variable delays which can occur. Frame Relay was
designed to operate at higher speeds on modern fiber optic networks.
 
     HUBS -- Collection centers located centrally in an area where
telecommunications traffic can be aggregated at a central point for transport
and distribution.
 
     ILEC -- (Incumbent Local Exchange Carrier) -- The incumbent carrier
providing Local Exchange Services.
 
     ISDN (INTEGRATED SERVICES DIGITAL NETWORK) -- A complex networking concept
designed to provide a variety of voice, data and digital interface standards.
Incorporated into ISDN are many new enhanced services, such as high speed data
file transfer, desk top videoconferencing, telepublishing, telecommuting,
telepresence learning (distance learning), remote collaboration (screened
sharing), data network linking and home information services.
 
     ISP -- Internet Service Provider
 
     INTERCONNECTION DECISIONS -- Rulings by the FCC announced in September 1992
and August 1993, which require the RBOCs and most other LECs to provide
interconnection in LEC central offices to any CAP, long distance carrier or end
user seeking such interconnection for the provision of interstate special access
and switched access transport services.
 
     INTER-LATA LONG DISTANCE -- Inter-LATA long distance calls are calls that
pass from one LATA to another. Typically, these calls are simply referred to as
"long distance" calls. At present, the RBOCs are prohibited from providing
Inter-LATA long distance service within their service areas.
 
     INTRA-LATA LONG DISTANCE -- lntra-LATA long distance calls, also known as
short haul calls, are those calls that originate and terminate within the same
LATA. Although most states allow some form of Intra-LATA competition, dialing
parity still does not exist, and very little ILEC intra-LATA revenue has been
won by competitors.
 
     IXC -- Inter-Exchange Carriers, usually referred to as long distance
providers. There are many facilities-based IXCs including AT&T, MCI, WorldCom,
Sprint and Frontier, as well as a select few CLECs that are authorized for IXC
service.
 
     KILOBIT -- One thousand bits of information. The information-carrying
capacity (i.e., bandwidth of a circuit may be measured in "kilobits per
second").
 
     LANS -- (Local Area Networks) -- The interconnection of computers for the
purpose of sharing files, programs and various devices such as work stations,
printers and high-speed modems. LANs may include dedicated computers or file
servers that provide a centralized source of shared files and programs.
 
     LATAS -- The geographically defined Local Access and Transport Areas in
which LECs are authorized by the MFJ to provide local exchange services. These
LATAs roughly reflect the population density of their respective states
(California has 11 LATAs while Wyoming has only one). There are 164 LATAs in the
United States.
 
     LOCAL COMPETITION -- The term "local competition" describes the events in
the local arena to afford true "co-carrier" status to CLECs. Specifically, the
ILECs, who once had a monopoly on local exchange telephone service, are
beginning to experience competition at the local level from CLECs and other
providers of local exchange services. Critical issues such as number
portability, dialing parity, reciprocal compensation arrangements, and number
assignments must be negotiated in order to ensure that true co-carrier status is
achieved for CLECs.
 
                                       A-3
<PAGE>   171
 
     LOCAL EXCHANGE AREAS -- A geographic area determined by the appropriate
state regulatory authority in which local calls generally are transmitted
without toll charges to the calling or called party.
 
     LOCAL EXCHANGE SERVICES -- Local Exchange Services generally refers to all
services provided by an ILEC or CLEC including local dial tone, centrex and Long
Distance Access Services. Sometimes also referred to as Local Telephone Services
and Local Telecommunications Services.
 
     LOCAL TELECOMMUNICATIONS OR LOCAL TELEPHONE SERVICES -- See Local Exchange
Services.
 
     LONG DISTANCE ACCESS SERVICES -- Long Distance Access Services are the
services provided by an ILEC or CLEC to a long distance company that connect the
IXC POP to end users, including Special Access Services and Switched Access
Services.
 
     LONG DISTANCE CARRIERS OR IXCS (INTEREXCHANGE CARRIERS) -- Long distance
carriers provide services between local exchanges on an interstate or intrastate
basis. A long distance carrier may offer services over its own or another
carrier's facilities. Major long distance carriers include AT&T, MCI, Sprint,
WorldCom and Frontier, but may also include resellers of long distance capacity.
 
     MEGABIT -- One million bits of information. The information-carrying
capacity (i.e., bandwidth) of a circuit may be measured in "megabits per
second."
 
     MFJ (MODIFIED FINAL JUDGMENT) -- The MFJ was an agreement made in 1982
between AT&T and the Department of Justice which forced the breakup of the old
Bell System. This judgment, also known as the Divestiture of AT&T, established
seven separate Regional Bell Operating Companies (RBOCs) and created two
distinct segments of telecommunications service: local and long distance. This
laid the groundwork for intense competition in the long distance industry, but
essentially created seven separate regionally-based local exchange service
monopolies. The MFJ has been superseded by The Telecommunications Act of 1996.
 
     MULTIPLEXING -- An electronic or optical process that combines a number of
lower speed transmission lines into one high-speed line by splitting the total
available bandwidth into narrower bands (frequency division) or by allotting a
common channel to several different transmitting devices one at a time in
sequence (time division). This is essentially a high-tech solution to a shortage
of capacity.
 
     NETWORK SYSTEMS INTEGRATION -- Involves the creation of a turnkey
telecommunications network including (i) route and site selection and obtaining
rights of way and legal authorizations to install the network; (ii) design and
engineering of the system, including technology and vendor assessment and
selection, determining fiber optic circuit capacity, and establishing
reliability/ flexibility standards; and (iii) project and construction
management, including contract negotiations, purchasing and logistics,
installation as well as testing and construction management.
 
     NODE -- An individual point of origination and termination of data on the
network transported using frame relay or similar technology.
 
     NUMBER PORTABILITY -- The ability of an end user to change local exchange
carriers while retaining the same telephone number. If number portability does
not exist, customers will have to change phone numbers when they change local
exchange carriers. This is considered to be anti-competitive because customers
are reluctant to change numbers, since they may lose business or confuse those
people trying to call them. It is currently being ascertained whether or not
number portability is technologically and economically feasible, and over what
time frame it can be implemented.
 
     OFF-NET -- a customer that is not physically connected to one of the
Company's networks but who is accessed through interconnection with an ILEC
network.
 
     ON-NET -- a customer that is physically connected to one of the Company's
networks.
 
                                       A-4
<PAGE>   172
 
     PBX -- A Private Branch Exchange is a switching system within an office
building which allows calls from outside to be routed directly to the individual
instead of through a central number. This PBX also allows for calling within an
office by way of four digit extensions. Centrex is a service which can simulate
this service from an outside switching source, thereby eliminating the need for
a large capital expenditure on a PBX.
 
     PCS -- Personal communications service. A type of wireless telephone system
that uses light, inexpensive handheld sets and communicates via low power
antennas.
 
     PHYSICAL COLLOCATION -- Physical Collocation occurs when a CLEC places its
own network connection equipment inside the ILEC central office. See Virtual
Collocation.
 
     POPS (POINTS OF PRESENCE) -- Locations where a long distance carrier has
installed transmission equipment in a service area that serves as, or relays
calls to, a network switching center of that long distance carrier.
 
     PUC (PUBLIC UTILITY COMMISSION) -- A state regulatory body, established in
most states, which regulates utilities, including telephone companies providing
intrastate services.
 
     PRIVATE LINE -- A private, dedicated telecommunications line connecting
different end user locations.
 
     PUBLIC SWITCHED NETWORK -- That portion of an ILEC's network available to
all users generally on a shared basis (i.e. not dedicated to a particular user).
Traffic along the public switched network is switched at the ILEC's central
offices.
 
     RBOCS -- Regional Bell Operating Companies. The seven local telephone
companies established by the MFJ. These RBOCs are prohibited from providing
inter-LATA services within their service areas and from manufacturing
telecommunications equipment.
 
     RECIPROCAL COMPENSATION -- The same compensation from an ILEC to a CLEC for
termination of a local call on the CLEC network, as the CLEC pays the ILEC for
termination of local calls on the ILEC network.
 
     REDUNDANT ELECTRONICS -- A telecommunications facility using two separate
electronic devices to transmit a telecommunications signal so that if one device
malfunctions, the signal may continue without interruption.
 
     ROBUST NETWORK -- High capacity networks which are capable of reaching a
significant portion of the identified business end users in the market and most,
if not all, of the ILEC's central offices.
 
     ROUTE MILES -- The number of miles of the telecommunications path in which
fiber optic cables are installed as it would appear on a network map.
 
     SECOND AND THIRD TIER MARKETS -- Metropolitan markets in the United States
with population bases ranging from 250,000 to two million.
 
     SPECIAL ACCESS SERVICES -- The lease of private, dedicated
telecommunications lines or "circuits" along the network of an ILEC or a CLEC
(such as the Company), which lines or circuits run to or from the long distance
carrier POPs. Examples of special access services are telecommunications lines
running between POPs of a single long distance carrier, from one long distance
carrier POP to the POP of another long distance carrier or from an end user to
its long distance carrier POP. Special access services do not require the use of
switches.
 
     SONET -- Synchronous Optical Network. SONET is the electronics and network
architecture which enables transmission of voice, video and data (multimedia) at
very high speeds. This state-of-the-art self-healing ring network offers
advantages over older linear networks in that a cut line or equipment failure
can be overcome by rerouting calls within the network. If the line is cut, the
traffic is simply reversed and sent to its destination around the other side of
the ring.
 
                                       A-5
<PAGE>   173
 
     SWITCH -- A sophisticated computer that accepts instructions from a caller
in the form of a telephone number. Like an address on an envelope, the numbers
tell the switch where to route the call. The switch opens or closes circuits or
selects the paths or circuits to be used for transmission of information.
Switching is a process of interconnecting circuits to form a transmission path
between users. Switches allow local telecommunications service providers to
connect calls directly to their destination, while providing advanced features
and recording connection information for future billing.
 
     SWITCHED ACCESS SERVICES -- Switched Access Services are the services
provided by an ILEC or CLEC to a long distance company that use one or more
Switches, in addition to Switched Access Transport, to connect the IXC POP to
end users.
 
     SWITCHED ACCESS ORIGINATION -- Switched Access Origination is that portion
of Switched Access Services relating to a long distance call originated by an
end user and carried over an ILEC or CLEC network to an IXC POP using a Switch.
 
     SWITCHED ACCESS TERMINATION -- Switched Access Termination is that portion
of Switched Access Services relating to a long distance call coming into an end
user over an ILEC or CLEC network from an IXC POP using a Switch.
 
     SWITCHED ACCESS TRANSPORT SERVICES -- Transportation of switched traffic
along dedicated lines between the ILEC central offices and long distance carrier
POPs.
 
     SWITCHED LOCAL SERVICES -- Switched Local Services are services provided by
an ILEC or CLEC using a Switch, including local dial tone and centrex, but not
including Intra-LATA Long Distance or Long Distance Access Services.
 
     SWITCHED TRAFFIC -- Telecommunications traffic along a switched network of
an ILEC, CLEC or IXC.
 
     VIRTUAL COLLOCATION -- Virtual Collocation is an alternative to Physical
Collocation in which CLECs connect their equipment to the ILECs facilities from
a remote location and request that the ILEC install the necessary electronics in
its central office which is then leased by the ILEC to the CLEC for charges
which are generally higher than the charges for physical collocation. However,
the CLEC avoids payment of the initial capital costs for the leased facilities
which the CLEC must incur under physical collocation.
 
     VOICE GRADE EQUIVALENT CIRCUIT (VGE) -- One DS-0. One voice grade
equivalent circuit is equal to 64 kilobits of bandwidth per second.

                                    PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The following is a summary of Section 145 of the General Corporation Law of
the State of Delaware.
 
     Subject to restrictions contained in the statute, a corporation may
indemnify any person, who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding by reason of
the fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorney's
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred in connection therewith if such person acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of the corporation, and, in connection with any criminal action or
proceeding, had no reasonable cause to believe that such person's conduct was
unlawful. A person who is successful on the merits or otherwise in any suit or
matter covered by the indemnification statute, shall be indemnified and
indemnification is otherwise authorized upon a determination that the person to
be indemnified has met the applicable standard of conduct required. Such
determination shall be made by a majority vote of the board of directors who
were not parties to such action, suit or proceeding, even though less than a
quorum, or if there are no such directors, or if such directors so direct, by
special independent counsel in a written opinion, or by the shareholders.
Expenses incurred in defense may be paid in advance upon receipt by the
corporation of written undertaking by or on behalf of the recipient to repay
such amount if it is ultimately determined that the recipient is not entitled to
indemnification under the statute. The indemnification provided by statute is
not exclusive of any other rights to which those seeking indemnification may be
entitled under any by-law, agreement, vote of shareholders or disinterested
directors or otherwise, and shall inure to the benefit of the heirs, executors
and administrators of such person. Insurance may be purchased on behalf of any
person entitled to indemnification by the corporation against any liability
asserted against him or her and incurred in an official capacity regardless of
whether the person could be indemnified under the statute. References to the
corporation include all constituent corporations absorbed in a consolidation or
merger as well as the resulting corporation and anyone seeking indemnification
by virtue of acting in some capacity with a constituent corporation would stand
in the same position as if such person had served the resulting or surviving
corporation in the same capacity.
 
     The Restated Certificate of Incorporation and By-Laws of the Company
provide for indemnification of directors and officers of the Company to the
maximum extent permitted by the General Corporation Law of the State of
Delaware.
 
     The directors and officers of the Company are insured under a policy of
directors' and officers' liability insurance.

     See Index to Exhibits.
 
ITEM 22. UNDERTAKINGS
 
     (a) The undersigned registrant hereby undertakes that insofar as
indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim of indemnification against
such liabilities (other than the payment by the registrant of
 
                                      II-1
<PAGE>   176
 
expenses incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
     (b) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
